技术领域technical field

本文描述的实施方案整体涉及用于电子设备的支架和支撑件。更具体地，这些实施方案涉及用于计算机显示器的平衡臂支撑件。Embodiments described herein relate generally to brackets and supports for electronic devices. More specifically, these embodiments relate to balance arm supports for computer monitors.

背景技术Background technique

计算机设备设计者通常期望控制计算机监视器或类似显示器在最适合于用户需要的任何高度和取向下的定位。支撑架用于定位显示器以适应不同高度、尺寸和姿势的用户和桌面表面。支撑架还可允许用户不太费力地调整监视器的定位。Computer equipment designers often desire to control the positioning of a computer monitor or similar display at any height and orientation that best suits the user's needs. The stand is used to position the monitor to accommodate users and desktop surfaces of varying heights, sizes and postures. The stand also allows the user to adjust the positioning of the monitor with less effort.

虽然各种现有的显示器支架为监视器提供倾斜、旋转和竖直高度调节，但这些特征通常以牺牲方便且自然使用为代价。许多特征要求用户处理显著的摩擦或滞后，这使得调节困难、麻烦且耗时。此类问题阻碍了支架具有高质量，并且使得支架更难以提供令人满意的用户体验。因此，不断需要对电子设备的支架和支撑件进行改进。While various existing monitor mounts provide tilt, swivel, and vertical height adjustment for monitors, these features often come at the expense of convenience and natural use. Many features require the user to deal with significant friction or lag, which makes adjustment difficult, cumbersome, and time-consuming. Such problems prevent the stand from being of high quality and make it more difficult for the stand to provide a satisfactory user experience. Accordingly, there is a continuing need for improvements in brackets and supports for electronic devices.

具体实施方式Detailed ways

现在将具体地参考在附图中示出的代表性实施方案。应当理解，以下描述不旨在将实施方案限制于任何优选实施方案。相反，其旨在涵盖可被包括在由所附权利要求书限定的所述实施方案的实质和范围内的另选形式、修改形式和等同形式。Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit embodiments to any preferred embodiments. On the contrary, it is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the described embodiments as defined by the appended claims.

以下公开涉及平衡的支撑臂设备，该平衡的支撑臂设备使用止转轭来调节至少一个偏置构件平衡件中的势能，该偏置构件平衡件具有恒定的弹性比率。系统的能量可始终平衡，使得当显示器向下移动并因此失去势能时，附加的相等能量存储在偏置构件的势能中。当显示器的势能改变时，偏置构件可被压缩或扩展，并且压缩或扩展可通过偏置构件与可平移轭或块结构之间的接触来提供，该可平移轭或块结构的平移由止转轭中的旋转轴驱动。The following disclosure relates to a balanced support arm apparatus that uses a yoke to accommodate potential energy in at least one biasing member balance having a constant spring ratio. The energy of the system can always be balanced so that when the display moves down and thus loses potential energy, additional equal energy is stored in the potential energy of the biasing member. When the potential energy of the display changes, the biasing member can be compressed or expanded, and the compression or expansion can be provided by contact between the biasing member and a translatable yoke or block whose translation is stopped by Driven by a rotating shaft in the yoke.

在一些实施方案中，止转轭的移动角速率是显示器支撑臂的旋转的两倍。因此，当臂处于完全竖直向上延伸的取向时，轭连杆也竖直向上延伸，并且当臂向下移动到竖直向下延伸的取向(例如，相对于向上延伸的取向旋转180度)时，止转轭行进90度，同时将能量存储在偏置构件(例如，压缩弹簧)中。偏置构件的压缩速率可与显示器的质量块的简单谐波运动匹配。参见图21。在一些实施方案中，支撑臂可具有约80度(即，相对于水平构型向上约40度并且相对于水平构型向下约40度)、约60度、约90度、约120度、约150度、约180度的总运动范围，或介于任何这些运动范围之间的拟合范围。In some embodiments, the angular rate of movement of the yoke is twice the rotation of the display support arm. Thus, when the arm is in the fully vertically upwardly extending orientation, the yoke link also extends vertically upwardly, and when the arm is moved down to the vertically downwardly extending orientation (eg, rotated 180 degrees relative to the upwardly extending orientation) , the yoke travels 90 degrees while storing energy in a biasing member (eg, a compression spring). The compression rate of the biasing member can be matched to the simple harmonic motion of the mass of the display. See Figure 21. In some embodiments, the support arm can have about 80 degrees (ie, about 40 degrees upward relative to the horizontal configuration and about 40 degrees downward relative to the horizontal configuration), about 60 degrees, about 90 degrees, about 120 degrees, A total range of motion of about 150 degrees, about 180 degrees, or a fitted range in between any of these ranges of motion.

在各种实施方案中，止转轭可由齿轮表面之间的2:1齿轮齿数比驱动，或者由支撑臂的四杆连杆布置中的连杆臂与作为止转轭的一部分的连杆臂之间的2:1角旋转速率驱动。当支撑臂处于水平构型时，止转轭可提供最大扭矩，并且可在升高构型和降低构型两者中提供减小的扭矩(即，相对于水平构型处的扭矩存在扭矩下降)。In various embodiments, the yoke may be driven by a 2:1 gear ratio between the gear surfaces, or by a link arm in a four-bar linkage arrangement that supports the arm and a link arm that is part of the yoke between 2:1 angular rotation rate drives. The yoke can provide maximum torque when the support arm is in the horizontal configuration, and can provide reduced torque in both the raised and lowered configurations (ie, there is a torque drop relative to the torque at the horizontal configuration ).

当支撑臂旋转时，支撑臂可相对于支架的支撑表面或基座以恒定的倾斜角保持显示器。例如，四杆连杆能够以保持第一竖直平面通过四杆连杆的一端(例如，通过一个端部支撑结构中的四杆连杆中的杆的一对枢转点)以及第二竖直平面通过四杆连杆的相对端(例如，通过第二端部支撑结构中的杆的一对枢转点)的平行运动的方式而被集成到臂中。因此，支撑臂可具有由四杆连杆或类似的平行运动设备参考的轭式平衡件。在一些实施方案中，支撑臂的端部还可向附接的显示器提供倾斜(即，显示器围绕连接到显示器的支撑臂的端部的旋转)。When the support arm is rotated, the support arm can hold the display at a constant angle of inclination relative to the support surface or base of the stand. For example, the four-bar linkage can pass through one end of the four-bar linkage (eg, through a pair of pivot points of the rods in the four-bar linkage in one end support structure) and the second vertical while maintaining the first vertical plane. The straight plane is integrated into the arm by means of parallel movement of opposite ends of the four-bar linkage (eg, by means of a pair of pivot points of the bars in the second end support structure). Thus, the support arm may have a yoke-type counterweight referenced by a four-bar linkage or similar parallel motion device. In some embodiments, the end of the support arm may also provide tilt (ie, rotation of the display about the end of the support arm attached to the display) to the attached display.

在一些实施方案中，平衡机构定位在支撑表面和电子显示器之间的支撑臂中的外壳中。平衡机构还可定位在显示器和支撑臂外部的支撑结构中，诸如通过定位在支撑支撑臂的与电子显示器相对定位的端部的支架结构中。In some embodiments, the balance mechanism is positioned in the housing in the support arm between the support surface and the electronic display. The balance mechanism may also be positioned in a support structure external to the display and support arm, such as by being positioned in a stand structure supporting the end of the support arm positioned opposite the electronic display.

具有1:1势能转换的平衡件与支撑臂的端部的平行移动的组合可提供电子显示器在竖直位置之间的经改善的平滑且精确的调节运动。调节显示器所需的输入力也可被约束到期望的水平，因为平衡件不一定使用摩擦来存储能量或防止支撑臂的移动。因此，支撑臂的可枢转部分中的摩擦(例如，四杆连杆中的摩擦盘)可被设计成提供所需的阻力量以进行调节。这样，支撑臂的运动可以是平滑的并且具有最小化的滞后。另外，支撑臂的显示器耦接端部可以附接到枢转构件，该枢转构件被配置为允许显示器相对于支撑臂的显示器耦接端部倾斜，而不会导致显示器耦接端部自身移动或旋转。The combination of the balance with 1:1 potential energy conversion and the parallel movement of the end of the support arm can provide improved smooth and precise adjustment movement of the electronic display between vertical positions. The input force required to adjust the display can also be constrained to a desired level since the balance does not necessarily use friction to store energy or prevent movement of the support arm. Thus, the friction in the pivotable portion of the support arm (eg, the friction disc in the four-bar linkage) can be designed to provide the desired amount of resistance to adjust. In this way, the movement of the support arm can be smooth and with minimal hysteresis. Additionally, the display-coupling end of the support arm may be attached to a pivot member configured to allow the display to tilt relative to the display-coupling end of the support arm without causing the display-coupling end to move itself or rotate.

以下参考附图讨论这些和其他实施方案。然而，本领域的技术人员将容易地理解，本文相对于这些附图所给出的详细描述仅出于说明性目的，而不应被理解为是限制性的。These and other embodiments are discussed below with reference to the figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these drawings is for illustrative purposes only and should not be construed in a limiting sense.

在外壳118内，支撑臂104可包括定位在第一端部120中的第一端部支撑件124和定位在第二端部122中的第二端部支撑件126。参见图5-7。第一端部支撑件124可耦接到支架106或支撑臂104外部的另一个支撑表面。第二端部支撑件126可耦接到显示器102或耦接到定位在外壳118的第二端部122处的显示器安装装置128。显示器安装装置128可附接到中间显示器连接器130。中间显示器连接器130可以是被配置为附接到显示器102的元件，诸如被磁性吸引到显示器102的磁性元件或被配置为与显示器102的一部分机械性互锁的联锁元件。外壳118能够相对于第一端部支撑件124和第二端部支撑件126绕图5,6和8所示的一对枢转轴线132,134旋转。Within thehousing 118 , thesupport arm 104 may include afirst end support 124 positioned in thefirst end 120 and asecond end support 126 positioned in thesecond end 122 . See Figures 5-7. Thefirst end support 124 may be coupled to thebracket 106 or another support surface external to thesupport arm 104 . Thesecond end support 126 may be coupled to thedisplay 102 or to adisplay mounting device 128 positioned at thesecond end 122 of thehousing 118 .Display mount 128 may be attached tointermediate display connector 130 . Theintermediate display connector 130 may be an element configured to attach to thedisplay 102 , such as a magnetic element that is magnetically attracted to thedisplay 102 or an interlocking element that is configured to mechanically interlock with a portion of thedisplay 102 . Thehousing 118 is rotatable relative to thefirst end support 124 and thesecond end support 126 about a pair of pivot axes 132 , 134 shown in FIGS. 5 , 6 and 8 .

第一杆136和第二杆138可附接到第一端部支撑件124上的枢转点140,142，并且可附接到第二端部支撑件126上的枢转点144,146。第一杆136和第二杆138可相对于其相应的连接的枢转点140,142,144,146枢转。第一杆136和第二杆138可在枢转点之间具有相等的长度。例如，第一杆136在枢转点140和144之间的长度可等于第二杆138在枢转点142,146之间的长度。第一杆136和第二杆138可平行于彼此布置在降低位置、水平位置和升高位置(即，分别为图10,12和14的位置)。因此，第一端部支撑件124上的枢转点140,142之间的距离可等于第二端部支撑件126上的枢转点144,146之间的距离。因此，这四个枢转点140,142可限定四边形平行四边形148的拐角，如图10,12和14所示。Thefirst rod 136 and thesecond rod 138 are attachable to pivotpoints 140 , 142 on thefirst end support 124 and to pivotpoints 144 , 146 on thesecond end support 126 . Thefirst lever 136 and thesecond lever 138 are pivotable relative to their respective connected pivot points 140 , 142 , 144 , 146 . Thefirst rod 136 and thesecond rod 138 may have equal lengths between the pivot points. For example, the length of thefirst rod 136 between the pivot points 140 and 144 may be equal to the length of thesecond rod 138 between the pivot points 142 , 146 . Thefirst rod 136 and thesecond rod 138 may be arranged parallel to each other in a lowered position, a horizontal position and a raised position (ie, the positions of FIGS. 10 , 12 and 14 , respectively). Thus, the distance between the pivot points 140 , 142 on thefirst end support 124 may be equal to the distance between the pivot points 144 , 146 on thesecond end support 126 . Thus, the fourpivot points 140 , 142 may define the corners of thequadrilateral parallelogram 148 , as shown in FIGS. 10 , 12 and 14 .

施加到显示器102(例如，F₁或F₂)或施加到支撑臂104的输入力可以使第一杆136和第二杆138相对于第一端部支撑件124旋转，旋转轴穿过枢转点140,142。第一杆136和第二杆138也可旋转地附接到第二端部支撑件126，因此杆136,138在第一端部支撑件124处的旋转也引起第二端部支撑件126处围绕其相关联的枢转点144,146的相等量值的旋转。为此，延伸穿过第一端部支撑件枢转点140,142的线总是平行于延伸穿过第二端部支撑件枢转点144,146的线。附近成对的枢转点140/142,144/146的平行移动确保当支撑臂104围绕枢转轴线132在图10,12和14所示的位置之间移动时，显示器102不相对于显示器安装装置128或显示器连接器130旋转。当杆136,138旋转时，第一端部枢转点140,142可相对于彼此静止，并且当杆136,138旋转时，第二端部枢转点144,146也可相对于彼此静止。在一些实施方案中，显示器安装装置128能够以允许显示器102倾斜而不移动支撑臂104的方式围绕第二枢转轴线134独立于外壳118并且独立于第二端部支撑件126旋转。An input force applied to the display 102 (eg, F₁ or F₂ ) or to thesupport arm 104 may cause the first andsecond levers 136 and 138 to rotate relative to thefirst end support 124 with the axis of rotation passing through the pivot Points 140,142. Thefirst rod 136 and thesecond rod 138 are also rotatably attached to thesecond end support 126, so rotation of therods 136, 138 at thefirst end support 124 also causes thesecond end support 126 to wrap around them Equal magnitude rotation of the associated pivot points 144 , 146 . To this end, the line extending through the first end support pivot points 140 , 142 is always parallel to the line extending through the second end support pivot points 144 , 146 . Parallel movement of the nearby pair of pivot points 140/142, 144/146 ensures that thedisplay 102 is not relative to thedisplay mounting device 128 as thesupport arm 104 moves about thepivot axis 132 between the positions shown in FIGS. 10, 12 and 14 Or thedisplay connector 130 rotates. The first end pivot points 140, 142 may be stationary relative to each other as therods 136, 138 rotate, and the second end pivot points 144, 146 may also be stationary relative to each other as therods 136, 138 rotate. In some embodiments, thedisplay mount 128 is rotatable about thesecond pivot axis 134 independently of thehousing 118 and independently of thesecond end support 126 in a manner that allows thedisplay 102 to be tilted without moving thesupport arm 104 .

第一杆136和第二杆138可被称为四杆连杆或四连接件、四接头、闭环连杆的一部分。第一杆136和第二杆138可以是四杆连杆中的两个连接件，并且第一端部支撑件124和第二端部支撑件126可以是剩余的两个连接件。第一杆136和第二杆138可旋转而不相对于彼此平移，并且第一端部支撑件124和第二端部支撑件126可相对于彼此平移而不相对于彼此旋转。Thefirst rod 136 and thesecond rod 138 may be referred to as a four-bar linkage or part of a four-link, four-joint, closed-loop linkage. Thefirst rod 136 and thesecond rod 138 may be the two links in the four-bar linkage, and thefirst end support 124 and thesecond end support 126 may be the remaining two links. Thefirst rod 136 and thesecond rod 138 can rotate relative to each other without translating relative to each other, and thefirst end support 124 and thesecond end support 126 can translate relative to each other without rotating relative to each other.

支撑臂104可包括至少一个四杆连杆。在一些实施方案中，四杆连杆定位在外壳118内的不同点处。例如，如图4,5和7所示，第三杆150和第四杆152可设置在外壳118中与第一杆136和第二杆138相对的一侧上。在一些实施方案中，多个四杆连杆可用完全分开的连接件或杆构造。在一些情况下，四杆连杆可共用连接件或杆，诸如第三杆150和第四杆152如何枢转地连接到与第一杆136和第二杆138相同的第一端部支撑件124和第二端部支撑件126。参见图5和7。Thesupport arm 104 may include at least one four-bar linkage. In some embodiments, the four-bar linkages are positioned at various points within thehousing 118 . For example, as shown in FIGS. 4 , 5 and 7 , thethird rod 150 and thefourth rod 152 may be disposed on the opposite side of thehousing 118 from thefirst rod 136 and thesecond rod 138 . In some embodiments, multiple four-bar linkages may be constructed with completely separate links or rods. In some cases, the four-bar linkage may share a connection or rod, such as how thethird rod 150 and thefourth rod 152 are pivotally connected to the same first end support as thefirst rod 136 and thesecond rod 138 124 andsecond end support 126 . See Figures 5 and 7.

外壳118的内部还可包括平衡机构154(即，平衡组件或储能结构)。平衡机构154可包括至少一个储能设备156和至少一个轭158。平衡机构154可被配置为当显示器102的势能响应于向上或向下移动而改变时在内部存储或释放势能。The interior of thehousing 118 may also include a balance mechanism 154 (ie, a balance assembly or energy storage structure).Balance mechanism 154 may include at least oneenergy storage device 156 and at least oneyoke 158 .Balance mechanism 154 may be configured to internally store or release potential energy as the potential energy ofdisplay 102 changes in response to moving up or down.

储能设备156可包括一个或多个弹簧(例如，可弹性压缩的线圈、气弹簧、弹性体材料、可弹性延伸的线圈、可重力位移的配重、缆线和滑轮、类似的设备以及它们的组合)。在一些实施方案中，弹簧以并列构型定位，这可减小支撑臂104的竖直厚度，同时仍然提供显著的弹簧力和储能容量。参见图7中的储能设备160。Theenergy storage device 156 may include one or more springs (eg, elastically compressible coils, gas springs, elastomeric materials, elastically extensible coils, gravitationally displaceable weights, cables and pulleys, similar devices, and the like) The combination). In some embodiments, the springs are positioned in a side-by-side configuration, which can reduce the vertical thickness of thesupport arms 104 while still providing significant spring force and energy storage capacity. Seeenergy storage device 160 in FIG. 7 .

储能设备156可定位在支撑臂104中或支撑臂的外部(参见图20)。储能设备156可通过被压缩(例如，就压缩弹簧而言)来储能，可通过膨胀(例如，就拉伸弹簧而言)来储能，或可通过移动(例如，就可移动配重而言)来储能。平衡机构154可被配置为确保储能设备156中存储的能量等于通过向下移动显示器102而损失的能量，并且确保从储能设备156损失的能量等于通过向上移动显示器102而获得的能量。Theenergy storage device 156 may be positioned in thesupport arm 104 or external to the support arm (see Figure 20). Theenergy storage device 156 may store energy by being compressed (eg, in the case of a compression spring), may be charged by expanding (eg, in the case of an extension spring), or may be charged by moving (eg, in the case of a movable counterweight) ) to store energy.Balance mechanism 154 may be configured to ensure that the energy stored inenergy storage device 156 is equal to the energy lost by movingdisplay 102 downward, and to ensure that energy lost fromenergy storage device 156 is equal to the energy gained by movingdisplay 102 upward.

压缩弹簧被示出为图5-15的储能设备156，并且弹簧被示出为在图11所示的降低位置具有最大压缩(即，沿着支撑臂104的长度尺寸的最小长度)。弹簧在图13所示的水平位置具有较小的压缩，并且在图15所示的升高位置具有最小压缩。因此，压缩弹簧在最小高度降低位置中存储最多的能量，并且在最大高度升高位置中存储最少的能量。The compression spring is shown as theenergy storage device 156 of FIGS. 5-15 , and the spring is shown with maximum compression (ie, the minimum length along the length dimension of the support arm 104 ) in the lowered position shown in FIG. 11 . The spring has less compression in the horizontal position shown in FIG. 13 and minimal compression in the raised position shown in FIG. 15 . Therefore, the compression spring stores the most energy in the minimum height lowered position and the least energy in the maximum height raised position.

储能设备156的压缩或扩展速率可与显示器102的质量的简单谐波运动相匹配。储能设备156可包括具有恒定弹性比率的线性弹簧以提供此行为。还可参见图21和下文的相关说明。The rate of compression or expansion of theenergy storage device 156 may be matched to the simple harmonic motion of the mass of thedisplay 102 . Theenergy storage device 156 may include a linear spring with a constant spring ratio to provide this behavior. See also Figure 21 and the related description below.

储能设备156可通过轭158的操作来调节其势能。轭158可包括接合储能设备156的可平移块162和用于调节块162的位置的平衡臂164。平衡臂164可在平衡枢转点166处安装到外壳118，并且可具有接触所述块162的表面170(参见图8)的从动件168。从动件168可为辊或圆形表面诸如凸轮从动件，并且可被配置为保持与表面170恒定接触。平衡臂164还可包括臂齿轮表面172，该臂齿轮表面被配置为接合第一端部支撑件124的端部支撑齿轮表面174。轭158可被称为止转轭或轭机构，其被配置为能够将平衡臂164的旋转运动转换为块162的平移运动。Theenergy storage device 156 may adjust its potential energy through the operation of theyoke 158 . Theyoke 158 may include atranslatable mass 162 that engages theenergy storage device 156 and abalance arm 164 for adjusting the position of themass 162 . Thebalance arm 164 may be mounted to thehousing 118 at thebalance pivot point 166 and may have afollower 168 that contacts the surface 170 (see FIG. 8 ) of theblock 162 .Follower 168 may be a roller or a circular surface such as a cam follower, and may be configured to maintain constant contact withsurface 170 . Thebalance arm 164 may also include anarm gear surface 172 configured to engage the endsupport gear surface 174 of thefirst end support 124 . Theyoke 158 may be referred to as a swivel yoke or a yoke mechanism that is configured to convert rotational motion of thebalance arm 164 to translational motion of themass 162 .

当支撑臂104移动时，外壳118旋转，从而相对于延伸穿过第一端部支撑件124的枢转轴线132移动平衡枢转点166。参见图8。齿轮表面172,174的接合使得平衡臂164围绕枢转点166旋转，从而驱动从动件168通过围绕枢转点166的弧形路径。从动件168的纵向位置(即从动件沿着外壳118的纵向轴线L(参见图11)的位置)因此随着外壳118的旋转而改变。在支撑臂104的最小降低位置处，从动件168处于远离枢转轴线132的最大纵向位移处，如图11所示。在支撑臂104的最大升高位置处，从动件168处于距枢转轴线132的最小纵向位移处，如图15所示。由于从动件168的弧形路径围绕枢转点166移动，与在支撑臂104处于升高位置时从动件168与枢转轴线132之间的纵向距离根据支撑臂104的旋转度的变化率相比，在支撑臂104处于降低位置时从动件168与枢转轴线132之间的纵向距离根据支撑臂104的旋转度的变化率较低。该变化率反映在图21的弹簧势能曲线2104的周期性正弦波状曲率中。As thesupport arm 104 moves, thehousing 118 rotates, thereby moving thebalance pivot point 166 relative to thepivot axis 132 extending through thefirst end support 124 . See Figure 8. Engagement of the gear surfaces 172 , 174 causes thebalance arm 164 to rotate about thepivot point 166 , thereby driving thefollower 168 through an arcuate path about thepivot point 166 . The longitudinal position of the follower 168 (ie the position of the follower along the longitudinal axis L (see FIG. 11 ) of the housing 118 ) thus changes as thehousing 118 is rotated. At the minimum lowered position of thesupport arm 104 , thefollower 168 is at its maximum longitudinal displacement away from thepivot axis 132 , as shown in FIG. 11 . At the maximum raised position of thesupport arm 104 , thefollower 168 is at a minimum longitudinal displacement from thepivot axis 132 , as shown in FIG. 15 . As the arcuate path of thefollower 168 moves about thepivot point 166 , the rate of change of the longitudinal distance between thefollower 168 and thepivot axis 132 when thesupport arm 104 is in the raised position as a function of the degree of rotation of thesupport arm 104 In contrast, the rate of change of the longitudinal distance between thefollower 168 and thepivot axis 132 as a function of the degree of rotation of thesupport arm 104 is lower when thesupport arm 104 is in the lowered position. This rate of change is reflected in the periodic sinusoidal curvature of the springpotential energy curve 2104 of FIG. 21 .

储能设备156可将可平移块162朝向枢转轴线132偏置。因此，从动件168沿着外壳118的纵向轴线朝向枢转轴线132的移动允许储能设备156扩展，并且从动件168朝向枢转轴线134的移动可压缩储能设备156。储能设备156的扩展可释放其势能，并且其压缩可存储势能。储能设备156的弹性特征可被设计成确保由支撑臂104的旋转引起的储能设备156的势能的变化精确地抵消由显示器102的质量块(以及附接到其的同样竖直移动的任何其他部件)的竖直移动引起的势能的变化。还参见图21及其在本文中的相关描述。Theenergy storage device 156 may bias thetranslatable mass 162 toward thepivot axis 132 . Accordingly, movement of thefollower 168 along the longitudinal axis of thehousing 118 toward thepivot axis 132 allows theenergy storage device 156 to expand, and movement of thefollower 168 toward thepivot axis 134 may compress theenergy storage device 156 . The expansion of theenergy storage device 156 can release its potential energy, and its compression can store the potential energy. The elastic characteristics of theenergy storage device 156 may be designed to ensure that changes in the potential energy of theenergy storage device 156 caused by rotation of thesupport arm 104 accurately counteract any similarly vertically moving mass by thedisplay 102 mass (and any attached thereto). change in potential energy caused by vertical movement of other components). See also Figure 21 and its related description herein.

臂齿轮表面172和支撑齿轮表面174之间的齿轮齿数比可被设计成提供支撑臂104围绕枢转轴线132的角位移与平衡臂164围绕平衡枢转点166的角位移的2:1比率。例如，如图11所示，支撑臂104可具有相对于水平轴线X成角度A₁定位的纵向轴线L，并且平衡臂164可具有的轴线P，该轴线P穿过平衡枢转点166以及相对于平行于纵向轴线L的轴线以角度B₁取向的从动件168的中心。在各种实施方案中，轴线P可延伸穿过枢转点166并且穿过平衡臂164中的另一个单个点。角度A₁指示支撑臂104在水平轴线X下方约45度角处，并且角度B₁指示从动件168在相对于水平轴线X约30度角处。The gear ratio betweenarm gear surface 172 andsupport gear surface 174 may be designed to provide a 2:1 ratio of the angular displacement ofsupport arm 104 aboutpivot axis 132 to the angular displacement ofbalance arm 164 aboutbalance pivot point 166 . For example, as shown in FIG. 11, thesupport arm 104 may have a longitudinal axis L positioned at_an angle A1 relative to the horizontal axis X, and thebalance arm 164 may have an axis P that passes through thebalance pivot point 166 and is relatively The center of thefollower 168 oriented at an angle B1 to_an axis parallel to the longitudinal axis L. In various embodiments, axis P may extend throughpivot point 166 and through another single point inbalance arm 164 . Angle A₁ indicates that thesupport arm 104 is at an angle of about 45 degrees below the horizontal axis X, and angle B₁ indicates that thefollower 168 is at an angle of about 30 degrees relative to the horizontal axis X. FIG.

在图13的水平构型中，支撑臂104已将其纵向轴线L旋转到从水平轴线X偏移约零度，并且角度B₂的量值相对于纵向轴线L已增加至约52.5度。因此，作为响应，角度A₁已从约负45度增加至约零度，并且角度B₁已增加约22.5度。到B₂的约22.5度变化为纵向轴线L的角位移量的约二分之一。In the horizontal configuration of Figure₁₃ , thesupport arm 104 has rotated its longitudinal axis L to approximately zero degrees offset from the horizontal axis X, and the magnitude of the angle B2 has increased relative to the longitudinal axis L to approximately 52.5 degrees. Thus, in response, angle A₁ has increased from about minus 45 degrees to about zero degrees, and angle B₁ has increased by about 22.5 degrees._The about 22.5 degree change to B2 is about one-half the amount of angular displacement of the longitudinal axis L.

在图15的升高构型中，支撑臂104已将其纵向轴线L旋转至水平轴线X上方约45度角A₂，并且角B₃已增加至约75度。因此，支撑臂104的纵向轴线L的每个角位移度与延伸穿过平衡枢转点166和平衡臂164上的另一个固定点的轴线P的角位移的约二分之一相关联。支撑臂104的旋转速率可以是轴P的旋转速率的两倍。In the raised configuration of Figure₁₅ , thesupport arm 104 has rotated its longitudinal axis L to an angle A2 of about 45 degrees above the horizontal axis X, and the angle_B3 has increased to about 75 degrees. Thus, each degree of angular displacement of the longitudinal axis L of thesupport arm 104 is associated with approximately one-half the angular displacement of the axis P extending through thebalance pivot point 166 and another fixed point on thebalance arm 164 . The rotation rate of thesupport arm 104 may be twice the rotation rate of the shaft P.

轭158的块162可在由储能设备156或平衡臂164驱动时在外壳118内平移。如图5,7,8和9所示，块162可包括装配到纵向细长狭槽178中的侧向延伸的轴176。纵向取向的狭槽178可形成于作为外壳118的一部分并且相对于该外壳静止的块中。因此，当支撑臂104如图10-15所示旋转时，可沿狭槽178引导轴176以限制块162相对于外壳118或储能设备156的旋转。轴176可约束块162沿着延伸穿过枢转轴线132,134的纵向轴线L平移。在一些实施方案中，轴176可包括轮、辊或类似设备以减小轴176和狭槽178之间的摩擦。在一些实施方案中，轴176从块162沿相反方向侧向延伸并进入定位在块162的相对侧上的两个狭槽178中。Mass 162 ofyoke 158 may translate withinhousing 118 when driven byenergy storage device 156 orbalance arm 164 . As shown in FIGS. 5 , 7 , 8 and 9 , theblock 162 may include a laterally extendingshaft 176 that fits into a longitudinallyelongated slot 178 . The longitudinally orientedslot 178 may be formed in a block that is part of thehousing 118 and is stationary relative to the housing. Accordingly, when thesupport arm 104 is rotated as shown in FIGS. 10-15 , theshaft 176 may be guided along theslot 178 to limit rotation of theblock 162 relative to thehousing 118 or theenergy storage device 156 . Theshaft 176 may constrain translation of theblock 162 along a longitudinal axis L extending through the pivot axes 132 , 134 . In some embodiments, theshaft 176 may include wheels, rollers, or similar devices to reduce friction between theshaft 176 and theslot 178 . In some embodiments, theshaft 176 extends laterally from theblock 162 in opposite directions and into twoslots 178 positioned on opposite sides of theblock 162 .

支撑臂104的角位移范围可通过外壳118与外壳118外部的表面之间的接触来限制，诸如通过外壳118与支架106之间或外壳118与显示器连接器130或显示器102之间的接触。在一些实施方案中，角位移的范围可通过在支撑臂104内移动的部件之间的接触来限制。例如，如图9所示，支撑臂104可包括角限制块180，该角限制块被配置为与外壳118一起围绕第一枢转轴线132旋转并且相对于第一端部支撑件124旋转。角限制块180可具有第一侧表面182和第二侧表面184，所述第一侧表面和第二侧表面被配置为当角限制块180相对于水平轴线X旋转到相应的预定最大角度和最小角度时与第一端部支撑件124的对应表面接触。The range of angular displacement ofsupport arm 104 may be limited by contact betweenhousing 118 and a surface external tohousing 118 , such as by contact betweenhousing 118 and stand 106 or betweenhousing 118 anddisplay connector 130 ordisplay 102 . In some embodiments, the range of angular displacement may be limited by contact between components moving withinsupport arm 104 . For example, as shown in FIG. 9 , thesupport arm 104 may include acorner limit block 180 configured to rotate with thehousing 118 about thefirst pivot axis 132 and relative to thefirst end support 124 . Thecorner stop 180 may have afirst side surface 182 and asecond side surface 184 that are configured to be rotated when thecorner stop 180 is rotated relative to the horizontal axis X to a corresponding predetermined maximum angle and The minimum angle is in contact with the corresponding surface of thefirst end support 124 .

角度C示出了第二侧表面184如何相对于水平轴线X以一定角度取向。当支撑臂104向下旋转(例如，旋转到图10的位置)时，第二侧表面184相对于枢转轴线132旋转，直到其接触第一端部支撑件124，从而防止外壳118相对于第一端部支撑件124进一步向下旋转。第一侧表面182执行用于向上旋转的类似功能。角度C以及第二侧表面184与第一端部支撑件124之间的距离可被设计成限定向下角位移的期望范围，并且类似的角度和距离可被设计成限定向上角位移的范围。两个侧表面182,184之间的角度可限定支撑臂104的角位移的总范围。Angle C shows how thesecond side surface 184 is oriented at an angle relative to the horizontal axis X. When thesupport arm 104 is rotated downward (eg, to the position of FIG. 10), thesecond side surface 184 rotates relative to thepivot axis 132 until it contacts thefirst end support 124, thereby preventing thehousing 118 from relative to thefirst end support 124. The oneend support 124 is further rotated downward. Thefirst side surface 182 performs a similar function for upward rotation. The angle C and the distance between thesecond side surface 184 and thefirst end support 124 can be designed to define a desired range of downward angular displacement, and similar angles and distances can be designed to define a range of upward angular displacement. The angle between the twoside surfaces 182 , 184 may define the overall range of angular displacement of thesupport arm 104 .

使用角限制块180限制角位移可防止外壳118与支架106或显示器102之间的接触，从而减少它们将彼此划伤或凹陷的可能性。其还可在支架106和显示器102之间提供预定量的间隙空间或偏移，这可有利地改善通过间隙或偏移的空气循环和线缆布线。Limiting the angular displacement using thecorner limiters 180 can prevent contact between thehousing 118 and thestand 106 or thedisplay 102, thereby reducing the likelihood that they will scratch or dent each other. It can also provide a predetermined amount of clearance space or offset between thestand 106 and thedisplay 102, which can advantageously improve air circulation and cable routing through the gap or offset.

图16-19示出了可以与支撑臂104类似的方式使用的支撑臂1604的另一个实施方案。在这些图中，具有类似编号的元件可起到与图1-15的实施方案的元件类似的功能。图16是处于降低位置的具有外壳1618的侧面板的支撑臂1604的侧视剖视图，其中顶部侧杆1636和底部侧杆1638被移除以露出内部部件(图18中示出了一个相对的顶部侧杆1686)。图17是处于水平位置的支撑臂1604的侧视图，并且图19是处于升高位置的支撑臂1604的侧视图。图18示出了处于水平位置的支撑臂1604的等轴视图，其中省略了外壳1618的侧部和顶部以及侧杆1636,1638。16-19 illustrate another embodiment of asupport arm 1604 that may be used in a similar manner to thesupport arm 104 . In these figures, like-numbered elements may serve similar functions as elements of the embodiments of FIGS. 1-15. 16 is a side cross-sectional view of thesupport arm 1604 with the side panel of thehousing 1618 in a lowered position with the top side bar 1636 and bottom side bar 1638 removed to reveal internal components (an opposite top is shown in FIG. 18 ). side bar 1686). Figure 17 is a side view of thesupport arm 1604 in a horizontal position, and Figure 19 is a side view of thesupport arm 1604 in a raised position. Figure 18 shows an isometric view of thesupport arm 1604 in a horizontal position with the sides and top of thehousing 1618 and the side bars 1636, 1638 omitted.

支撑臂1604可包括至少一个四杆连杆以控制显示器102相对于支架106的平行运动。因此，支撑臂1604可以与支撑臂104类似的方式操作，如图10,12和14所示。因此，图16-19示出了支撑臂1604内的平衡机构1658的特征。平衡机构1658可包括在引导显示器102的运动的四杆连杆内的四杆连杆。至少一个储能设备1656可定位在外壳1618中并且可与平衡块1662和第二端部支撑件1626耦接。块1662可响应于由储能设备1656和包括平衡臂1664和转换臂1688的平衡连杆施加的力而在外壳1618内平移。平衡臂1664可在平衡枢转点1666处枢转地连接到外壳1618，并且可在从动件1668处接触块1662。转换臂1688可在端部支撑件枢转点1690处枢转地连接到第一端部支撑件1624，并且在臂枢转点1692处枢转地连接到平衡臂1664。枢转点1666,1690,1692和外壳1618相对于第一端部支撑件1624的枢转轴线可在支撑臂1604内形成四杆连杆的接头。外壳1618、第一端部支撑件1624、平衡臂1664和转换臂1688可为平衡机构的四杆连杆中的连接件。Thesupport arm 1604 may include at least one four-bar linkage to control the parallel movement of thedisplay 102 relative to thestand 106 . Accordingly, thesupport arm 1604 may operate in a similar manner to thesupport arm 104, as shown in Figures 10, 12 and 14. Accordingly, Figures 16-19 illustrate features of thebalance mechanism 1658 within thesupport arm 1604.Balance mechanism 1658 may include a four-bar linkage within a four-bar linkage that directs movement ofdisplay 102 . At least oneenergy storage device 1656 can be positioned in thehousing 1618 and can be coupled with thecounterweight 1662 and thesecond end support 1626 .Mass 1662 can translate withinhousing 1618 in response to forces applied byenergy storage device 1656 and a balance link includingbalance arm 1664 andtransition arm 1688 .Balance arm 1664 can be pivotally connected tohousing 1618 atbalance pivot point 1666 and can contact block 1662 atfollower 1668 . Thetransition arm 1688 is pivotally connected to thefirst end support 1624 at an endsupport pivot point 1690 and to thebalance arm 1664 at anarm pivot point 1692 . The pivot points 1666 , 1690 , 1692 and the pivot axis of thehousing 1618 relative to thefirst end support 1624 may form a four-bar linkage joint within thesupport arm 1604 .Housing 1618,first end support 1624,balance arm 1664, andtransition arm 1688 may be connections in a four-bar linkage of a balance mechanism.

当块1662沿着支撑臂1604的纵向轴线平移时，储能设备1656可存储或释放势能。平衡臂1664的旋转可由转换臂1688驱动，而不是由诸如上文相对于其他实施方案所述的齿轮相互作用驱动。如图16-19所示，当支撑臂1604旋转时，外壳1618相对于第一端部支撑件1624旋转。因为平衡臂1664在枢转点1666处附接到外壳1618，所以平衡臂1664与外壳1618一起相对于第一端部支撑件1624移动。平衡枢转点1666和端部支撑件枢转点1690之间的距离随着外壳1618的移动而改变，因此转换臂1688相对于第一端部支撑件1624旋转。由于臂枢转点1692处的附接，平衡臂1664也同时围绕平衡枢转点1666旋转。各个枢转点1666,1690,1692与从动件1668之间的距离可提供外壳1618的角位移与通过平衡枢转点1666和平衡臂1664上的另一个点(例如，从动件1668)或通过平衡臂1664上的另两个一致点的轴线的角位移的2:1比率。Theenergy storage device 1656 may store or release potential energy as themass 1662 is translated along the longitudinal axis of thesupport arm 1604. Rotation ofbalance arm 1664 may be driven by switchingarm 1688 rather than by gear interaction such as described above with respect to other embodiments. As shown in Figures 16-19, when thesupport arm 1604 is rotated, thehousing 1618 is rotated relative to thefirst end support 1624. Because thebalance arm 1664 is attached to thehousing 1618 at thepivot point 1666, thebalance arm 1664 moves with thehousing 1618 relative to thefirst end support 1624. The distance between thebalance pivot point 1666 and the endsupport pivot point 1690 changes as thehousing 1618 moves, so that theswitch arm 1688 rotates relative to thefirst end support 1624 . Due to the attachment atarm pivot point 1692,balance arm 1664 also rotates aboutbalance pivot point 1666 at the same time. The distance between eachpivot point 1666 , 1690 , 1692 and thefollower 1668 may provide the angular displacement of thehousing 1618 relative to the difference between the angular displacement of thehousing 1618 through thebalance pivot point 1666 and another point on the balance arm 1664 (eg, the follower 1668 ) or A 2:1 ratio of the angular displacement of the axis through the other two coincident points on thebalance arm 1664.

例如，如图16所示，穿过臂枢转点1692和从动件1668的轴线大致平行于外壳1618的纵向轴线。在外壳1618向上旋转约90度之后，如图19所示，穿过元件1668和1692的相同轴线相对于外壳1618的纵向轴线成约45度角。该转换比率可控制块1662沿外壳1618的纵向轴线的平移量，并且因此可根据需要控制储能设备1656的势能的变化，以抵消连接的显示器102的质量块的势能的变化。还参见图21和本文的相关说明。For example, as shown in FIG. 16 , the axis passing through thearm pivot point 1692 and thefollower 1668 is generally parallel to the longitudinal axis of thehousing 1618 . After thehousing 1618 has been rotated upward about 90 degrees, as shown in FIG. This conversion ratio can control the amount of translation of themass 1662 along the longitudinal axis of thehousing 1618 , and thus can control changes in the potential energy of theenergy storage device 1656 as needed to counteract changes in the potential energy of the masses of the attacheddisplay 102 . See also Figure 21 and related descriptions herein.

在一些实施方案中，第一端部支撑件1624可包括角位移限制特征部。转换臂1688可定位在具有下侧表面1696和上侧表面1698的第一端部支撑件1624中的凹槽1694内。下侧表面1696和上侧表面1698可在外壳1618的相应最小旋转位置和最大旋转位置处接触转换臂1688，如图16和19所示。因此，由下侧表面1696和上侧表面1698形成的角度可限定转换臂1688的运动范围并且因此可限定整个支撑臂1604的运动范围。转换臂1688与侧表面1696,1698之间的干涉可防止平衡臂1664及其附接的外壳1618移动。In some embodiments, thefirst end support 1624 can include angular displacement limiting features. Thetransition arm 1688 can be positioned within agroove 1694 in thefirst end support 1624 having alower side surface 1696 and anupper side surface 1698 . Thelower side surface 1696 and theupper side surface 1698 may contact thetransition arm 1688 at respective minimum and maximum rotational positions of thehousing 1618 as shown in FIGS. 16 and 19 . Accordingly, the angle formed by thelower side surface 1696 and theupper side surface 1698 may define the range of motion of thetransition arm 1688 and thus may define the range of motion of theentire support arm 1604 . Interference between thetransition arm 1688 and the side surfaces 1696, 1698 may prevent movement of thebalance arm 1664 and its attachedhousing 1618.

图20示出了支撑系统2000的另一个实施方案，其中显示器2002通过连杆2004安装到支架2006，该连杆具有连杆2004外部和支架2006内的平衡机构2008。在该实施方案中具有类似名称的元件可起到与本文所述的其他实施方案类似的功能。FIG. 20 shows another embodiment of thesupport system 2000 in which thedisplay 2002 is mounted to thestand 2006 by alink 2004 having abalance mechanism 2008 outside thelink 2004 and within thestand 2006. Similar-named elements in this embodiment may serve similar functions as other embodiments described herein.

连杆2004可为具有四个枢转点2010,2012,2014,2016的四杆平行四边形连杆。在该实施方案中，显示器2002的外壳提供联接枢转点2010和2012的四杆构型的一部分。支架2006的外壳提供联接枢转点2014和2016的四杆构型的一部分。在一些实施方案中，单独的杆可分别联接点2010/2012和2014/2016，并且那些单独的杆可安装到显示器2002或支架2006(例如，类似于第一端部支撑件124和第二端部支撑件126)。因此，当连杆2004的第一杆2020和第二杆2022旋转时，由于穿过点2010和2012的线平行于穿过点2014和2016的线，因此显示器2002可平行于支架2006的竖直轴线移动。Link 2004 may be a four-bar parallelogram link with fourpivot points 2010, 2012, 2014, 2016. In this embodiment, the housing ofdisplay 2002 provides part of a four-bar configuration linkingpivot points 2010 and 2012. The housing ofbracket 2006 provides part of a four-bar configuration that couplespivot points 2014 and 2016 . In some embodiments, separate rods can be coupled topoints 2010/2012 and 2014/2016, respectively, and those separate rods can be mounted to display 2002 or stand 2006 (eg, similar tofirst end support 124 and second end part support 126). Thus, as thefirst rod 2020 and thesecond rod 2022 of thelink 2004 rotate, thedisplay 2002 can be parallel to the vertical of thestand 2006 since the line passing through thepoints 2010 and 2012 is parallel to the line passing through thepoints 2014 and 2016 Axis moves.

平衡机构2008可具有转换臂2023，所述转换臂在第一杆2020和第二杆2022中的至少一者上的枢转点2024处联接到杆中的一者。转换臂2023可在臂枢转点2025处枢转地附接到平衡臂2026。平衡臂2026可在平衡枢转点2028处枢转地附接到支架2006的外壳，并且可具有从动件2030部分，该从动件部分接合定位在支架2006内的可平移块2032。块2032与储能设备2034接触，并且储能设备2034在一端2036处被约束。Thebalance mechanism 2008 may have atransition arm 2023 coupled to one of the levers at apivot point 2024 on at least one of thefirst lever 2020 and thesecond lever 2022 . Theconversion arm 2023 is pivotally attached to thebalance arm 2026 at thearm pivot point 2025 . Thebalance arm 2026 can be pivotally attached to the housing of thebracket 2006 at abalance pivot point 2028 and can have afollower 2030 portion that engages atranslatable block 2032 positioned within thebracket 2006 .Block 2032 is in contact withenergy storage device 2034 , andenergy storage device 2034 is restrained at oneend 2036 .

当连杆2004使杆2020,2022旋转时，枢转点2024可沿着弧形路径围绕枢转点2014移动。枢转点2024的移动驱动臂枢转点2025和平衡臂2026围绕平衡枢转点2028的旋转。平衡臂2026的旋转引起从动件2030的竖直运动，从而压缩或扩展储能设备2034，同时底端2036相对于支架2006保持静止。因此，该实施方案示出了四杆连杆2004可如何支持和引导显示器2002的运动，并且止转轭式平衡件可被定位在连杆2004的外部。When thelink 2004 rotates therods 2020, 2022, thepivot point 2024 can move around thepivot point 2014 along an arcuate path. Movement ofpivot point 2024 drives rotation ofarm pivot point 2025 andbalance arm 2026 aboutbalance pivot point 2028 . Rotation ofbalance arm 2026 causes vertical movement offollower 2030 , thereby compressing or expandingenergy storage device 2034 , whilebottom end 2036 remains stationary relative tobracket 2006 . Thus, this embodiment shows how the four-bar linkage 2004 can support and guide the movement of thedisplay 2002 , and the yoke-type counterweight can be positioned outside thelinkage 2004 .

图21提供了根据本公开的实施方案的能量与臂角度的曲线图2100。臂角度可被定义为支撑臂(例如，104或1604)相对于水平方向(例如，水平轴线X)的角度。重力势能2102可被定义为显示器的质量块和支撑组件的任何其他连接部件的随支撑臂的移动而变化的势能。如本文所定义，当支撑臂水平时，重力势能2102为零。重力势能随着支撑臂升高而增加，并且其随着支撑臂降低而降低。21 provides agraph 2100 of energy versus arm angle in accordance with an embodiment of the present disclosure. The arm angle may be defined as the angle of the support arm (eg, 104 or 1604 ) relative to the horizontal (eg, horizontal axis X). Gravitationalpotential energy 2102 may be defined as the potential energy of the mass of the display and any other connecting components of the support assembly as a function of movement of the support arm. As defined herein, when the support arm is horizontal, the gravitationalpotential energy 2102 is zero. The gravitational potential energy increases as the support arm is raised, and it decreases as the support arm is lowered.

为了确保支撑臂的平滑和不费力的操作，可经由平衡机构控制系统中的弹簧或其他储能设备的势能2104，以具有以与重力势能2102大小相同方向相反的速率变化的量值。因此，系统能量2106(其表示所有臂角度下的重力势能2102和弹簧势能2104的总和)可在臂旋转时保持恒定。因此，需要非常小的输入力来改变显示器的势能(即，竖直位置)，因为弹簧势能提供补充能量以在显示器移动时帮助支撑臂的旋转。重力和弹簧势能的变化可在量值上与显示器和所连接的移动部件的质量的简单谐波运动相关联。To ensure smooth and effortless operation of the support arm, thepotential energy 2104 of a spring or other energy storage device in the system can be controlled via a balance mechanism to have a magnitude that changes at a rate that is opposite in the same direction as the gravitationalpotential energy 2102. Thus, thesystem energy 2106, which represents the sum of the gravitationalpotential energy 2102 and the springpotential energy 2104 at all arm angles, may remain constant as the arm rotates. Therefore, very little input force is required to change the potential energy (ie, vertical position) of the display, as the spring potential energy provides supplemental energy to assist the rotation of the support arm as the display moves. Changes in gravity and spring potential energy can be correlated in magnitude to simple harmonic motion of the mass of the display and connected moving parts.

Therefore, different privacy practices should be maintained in each country for different types of personal data.

不管前述情况如何，本公开还预期用户选择性地阻止使用或访问个人信息数据的实施方案。即本公开预期可提供硬件元件和/或软件元件，以防止或阻止对此类个人信息数据的访问。例如，就广告递送服务而言，本发明技术可被配置为在注册服务期间或之后任何时候允许用户选择“选择加入”或“选择退出”参与对个人信息数据的收集。在另一示例中，用户可以选择不为目标内容递送服务提供情绪相关数据。在另一个示例中，用户可选择限制情绪相关数据被保持的时间长度，或完全禁止基础情绪状况的开发。除了提供“选择加入”和“选择退出”选项外，本公开设想提供与访问或使用个人信息相关的通知。例如，可在下载应用时向用户通知其个人信息数据将被访问，然后就在个人信息数据被应用访问之前再次提醒用户。Regardless of the foregoing, the present disclosure also contemplates implementations in which users selectively block the use or access to personal information data. That is, the present disclosure contemplates that hardware elements and/or software elements may be provided to prevent or prevent access to such personal information data. For example, with respect to advertising delivery services, the present technology may be configured to allow users to "opt-in" or "opt-out" to the collection of personal information data during registration for the service or at any time thereafter. In another example, the user may choose not to provide sentiment-related data for the targeted content delivery service. In another example, the user may choose to limit the length of time that mood-related data is retained, or to disable the development of the underlying mood condition altogether. In addition to providing "opt-in" and "opt-out" options, this disclosure contemplates providing notices related to access or use of personal information. For example, the user can be notified when the application is downloaded that their personal information data will be accessed, and then the user is reminded again just before the personal information data is accessed by the application.

此外，本公开的目的是应管理和处理个人信息数据以最小化无意或未经授权访问或使用的风险。一旦不再需要数据，通过限制数据收集和删除数据可最小化风险。此外，并且当适用时，包括在某些健康相关应用程序中，数据去标识可用于保护用户的隐私。可在适当时通过移除具体标识符(例如，出生日期等)、控制所存储数据的量或特异性(例如，在城市级别而不是在地址级别收集位置数据)、控制数据如何被存储(例如，在用户上聚集数据)、和/或其他方法来促进去标识。Furthermore, the purpose of this disclosure is that personal information data should be managed and processed to minimize the risk of unintentional or unauthorized access or use. Risk is minimized by limiting data collection and deleting data once it is no longer needed. Additionally, and when applicable, including in certain health-related applications, data de-identification may be used to protect the privacy of users. This can be done by removing specific identifiers (eg, date of birth, etc.), controlling the amount or specificity of the data stored (eg, collecting location data at the city level instead of the address level), controlling how the data is stored (eg, , aggregate data on users), and/or other methods to facilitate de-identification.

因此，虽然本公开广泛地覆盖了使用个人信息数据来实现一个或多个各种所公开的实施方案，但本公开还预期各种实施方案也可在无需访问此类个人信息数据的情况下被实现。即，本发明技术的各种实施方案不会由于缺少此类个人信息数据的全部或一部分而无法正常进行。例如，可通过基于非个人信息数据或绝对最低数量的个人信息诸如与用户相关联的设备所请求的内容、对内容递送服务可用的其他非个人信息或公开可用的信息来推断偏好，从而选择内容并将该内容递送至用户。Thus, while this disclosure broadly covers the use of personal information data to implement one or more of the various disclosed embodiments, this disclosure also contemplates that the various embodiments may also be used without access to such personal information data. accomplish. That is, various implementations of the present technology will not fail due to lack of all or a portion of such personal information data.
