The steps are cumbersome and the user experience is poor.

In addition, when the user stops using it, the fixed relationship with the user can be automatically released, reducing the manual adjustment process of the user.
根据本实用新型的一个方面，提供一种头戴显示设备，如图2-4所示，包括设备主体1和与设备主体1连接围合成佩戴部的绑带2，还包括接近传感器3、压力传感器4、传动组件5和电机6。接近传感器3和压力传感器4设置在设备主体1或绑带2上，压力传感器4朝向绑带2与设备主体1围合成的佩戴部内侧，感应佩戴部内侧设备主体1或绑带2所受到的压力。接近传感器3和压力传感器4分别与电机6电连接，能够发送电信号，用于控制电机6的运转或停止。电机6为双向电机，能够正向转动和反向转动，即相对于电机6，其传动轴能够顺时针转动或逆时针转动。电机6通过传动组件5与绑带2传动连接，绑带2在电机6的驱动下能够相对于设备主体1收缩或扩张；例如，在其他的实施方式中，传动组件5可以是一个圆柱销，电机6驱动圆柱销自转，圆柱销的侧面设置有贯穿的开口，绑带2穿过贯穿的开口，随着圆柱销的自转，绑带2会被缠绕在圆柱销上，实现相对于设备主体1收缩或扩张，本实用新型对传动组件5的传动方式并不限制，能够带动绑带2相对于设备主体1收缩或扩张即可。According to one aspect of the present invention, a head-mounted display device is provided, as shown in Figure 2-4, including a device main body 1 and a strap 2 connected to the device main body 1 to form a wearing part, and also includes a proximity sensor 3, a pressure Sensor 4, transmission assembly 5 and motor 6. The proximity sensor 3 and the pressure sensor 4 are arranged on the device main body 1 or the strap 2. The pressure sensor 4 faces the inner side of the wearing part surrounded by the strap 2 and the device main body 1, and senses the impact on the device main body 1 or the strap 2 inside the wearing part. pressure. The proximity sensor 3 and the pressure sensor 4 are electrically connected to the motor 6 respectively, and can send electrical signals to control the operation or stop of the motor 6 . The motor 6 is a bidirectional motor, capable of forward rotation and reverse rotation, that is, relative to the motor 6, its transmission shaft can rotate clockwise or counterclockwise. The motor 6 is connected to the strap 2 through the transmission assembly 5, and the strap 2 can shrink or expand relative to the device main body 1 under the drive of the motor 6; for example, in other embodiments, the transmission assembly 5 can be a cylindrical pin, The motor 6 drives the cylindrical pin to rotate. The side of the cylindrical pin is provided with a through opening, and the strap 2 passes through the through opening. With the rotation of the cylindrical pin, the strap 2 will be wound on the cylindrical pin to realize relative to the equipment body 1 Contraction or expansion, the utility model does not limit the transmission mode of the transmission assembly 5, as long as it can drive the strap 2 to contract or expand relative to the main body 1 of the device.
接近传感器3感应与物体之间的距离，设定有第一预设值。压力传感器4感应压力，设定有第二预设值，第二预设值的设定值大于压力传感器4不受外力时的初始值，可以理解为，在自然状态下，因为不受外力，初始值假设为0，那么设定值就大于0。The proximity sensor 3 senses the distance to the object and is set with a first preset value. The pressure sensor 4 senses the pressure and is set with a second preset value. The set value of the second preset value is greater than the initial value when the pressure sensor 4 is not subjected to external force. It can be understood that in a natural state, because it is not subject to external force, The initial value is assumed to be 0, then the set value is greater than 0.
在使用时，接近传感器3打开处于探测状态，当接近传感器3探测到物体或者探测到与物体之间的距离小或等于第一预设值时，电机6正向转动，驱动绑带2相对于设备主体1收缩，不需要使用者手动调节。接近传感器3探测到的可以是使用者进入佩戴部的身体部分，也可以是使用者进入佩戴部的身体部分触发的一些其他机构遮挡住接近传感器3，本实用新型对此并不限制。本领域技术人员可以理解，此处所说的正向转动是一个相对概念，指的是能够驱动绑带2相对于设备主体1收缩的转动方向，后文中所述的正向转动，正转均是相对概念，在此不再赘述。When in use, the proximity sensor 3 is turned on and is in the detection state. When the proximity sensor 3 detects an object or detects that the distance between the object and the object is small or equal to the first preset value, the motor 6 rotates forward to drive the strap 2 relative to the first preset value. The main body 1 of the device is retracted without manual adjustment by the user. What the proximity sensor 3 detects may be the body part of the user entering the wearing part, or some other mechanism triggered by the user entering the body part of the wearing part blocks the proximity sensor 3, which is not limited by the present invention. Those skilled in the art can understand that the positive rotation mentioned here is a relative concept, which refers to the direction of rotation that can drive the strap 2 to shrink relative to the main body 1 of the device. The relative concept will not be repeated here.
压力传感器4感应绑带2或设备主体1与使用者之间的压力变化，当压力传感器4感应到的压力值等于设定的第二预设值时，电机6停止工作。第二预设值是一个预先设定的能够使使用者感到舒适，并能将头戴显示设备与使用者之间保持固定的数值，可以是一个固定值，也可以是一个区间范围值，本领域技术人员可以根据需要进行选择，本申请对此并不限制。The pressure sensor 4 senses the pressure change between the strap 2 or the device main body 1 and the user, and when the pressure value sensed by the pressure sensor 4 is equal to the set second preset value, the motor 6 stops working. The second preset value is a preset value that can make the user feel comfortable and keep the head-mounted display device and the user fixed. It can be a fixed value or an interval value. Those skilled in the art can make selections as needed, which is not limited in the present application.
关于第一预设值和第二预设值的设定，可以是产品生产时设定调节完成，也可以是使用者自己设定调节；第二预设值的大小可以通过人机系统模拟，综合实际测量所得，也可以是用户根据自己的喜好进行自定义调节，调节成固定值或调节区间范围，本实用新型对此均并不限制。Regarding the setting of the first preset value and the second preset value, it can be set and adjusted during product production, or it can be set and adjusted by the user himself; the size of the second preset value can be simulated by the man-machine system, Based on the actual measurement results, the user can also perform self-defined adjustment according to his own preferences, and adjust it to a fixed value or an adjustment range, which is not limited by the present invention.
本实用新型的头戴显示设备能够实现头戴显示设备与使用者自动固定，减少了使用者手动调节的麻烦，能有效提高使用者的使用体验；对于产品来说，提高了产品的档次感。The head-mounted display device of the utility model can automatically fix the head-mounted display device and the user, reduces the trouble of manual adjustment by the user, and can effectively improve the user experience; for the product, the sense of grade of the product is improved.
本领域技术人员可以根据控制逻辑关系来进行相应的控制电路设计。Those skilled in the art can design corresponding control circuits according to the control logic relationship.
可选地，当压力传感器4感应到的压力值大于第二预设值时，电机6反向转动，驱动绑带2相对于设备主体1扩张。由于在电机6转动的驱动过程中，感应到的压力值的变化是非常快速的，容易造成电机停止转动后，实际压力大于设定的第二预设值，造成配戴不适，通过电机6反向转动，能够使得头戴显示设备自动的不断调节，直至达到压力传感器4感应到的压力为设定的第二预设值。本领域技术人员可以理解，在此基础上，可以在出厂设定时，在第二预设值的基础上始终增加一个提前量，使得电机在停止转动后，就能达到所需要的设定值，不需要往复自动调节。另一方面，在需要取下头戴显示设备时，通过改变第二预设值，就能实现头戴显示设备自动松脱，解除与使用者的固定。Optionally, when the pressure value sensed by the pressure sensor 4 is greater than the second preset value, the motor 6 rotates in reverse to drive the strap 2 to expand relative to the device main body 1 . Since the change of the sensed pressure value is very fast during the driving process of the motor 6, it is easy to cause the actual pressure to be greater than the second preset value after the motor stops rotating, resulting in discomfort when wearing. Rotating in the opposite direction can make the head-mounted display device automatically and continuously adjust until the pressure sensed by the pressure sensor 4 reaches the set second preset value. Those skilled in the art can understand that on this basis, an advance amount can always be added on the basis of the second preset value at the factory setting, so that the motor can reach the required set value after it stops rotating. , no reciprocating automatic adjustment is required. On the other hand, when it is necessary to take off the head-mounted display device, by changing the second preset value, the head-mounted display device can be automatically loosened and fixed to the user.
可选地，接近传感器3和压力传感器4分别与电机6电连接，压力传感器4的优先级高于接近传感器3的优先级。Optionally, the proximity sensor 3 and the pressure sensor 4 are electrically connected to the motor 6 respectively, and the priority of the pressure sensor 4 is higher than that of the proximity sensor 3 .

As shown in FIG. 3 , the proximity sensor 3 can be arranged on the device main body 1. In other specific embodiments, the proximity sensor 3 can also be arranged on the strap 2 or respectively arranged on the device body 1 and the strap 2. Above, this application is not limited to this. As shown in Figure 3, the proximity sensor 3 can be directed towards the inner side of the wearing part formed by the strap 2 and the device main body 1. When the user is wearing it, it can directly detect whether the user is wearing it, and send an electrical signal, reducing the risk of misuse. In other embodiments, the proximity sensor 3 may not face the inside of the wearing part, but after the user wears it, use the hand to block the proximity sensor 3 and make it send an electrical signal for control. limit.
可选地，如图2和图3中所示的，头戴显示设备包括有若干个压力传感器4，间隔设置在绑带2的内表面上，感应绑带2上所受到的压力，用于全面的感应使用者与绑带2之间的压力，提高感应的准确定，保证佩戴的牢固性和舒适性。同时，在他的具体实施方式中，所述压力传感器4也可以是设置在设备主体1，朝向绑带2与设备主体1围合成的佩戴部内侧，感应压力，本申请对此并不限制。在图2和图3中所示的实施方式中，通过绑带2的收缩与扩张实现固定，感应绑带2上所受到的压力最为直接，也更接准确。在使用是，控制电机的第二预设值的设定值可以是若干个压力传感器4感应到的平均值，也可以是设定值为区间范围值，若干个压力传感器4感应到的压力均落入设定值的范围内或者是若干个压力传感器4感应到的平均值落入设定值的范围内，本申请对此并不限制。Optionally, as shown in FIG. 2 and FIG. 3 , the head-mounted display device includes several pressure sensors 4 arranged at intervals on the inner surface of the strap 2 to sense the pressure on the strap 2 for Comprehensively sense the pressure between the user and the strap 2, improve the accuracy of the sensing, and ensure the firmness and comfort of wearing. Meanwhile, in his specific embodiment, the pressure sensor 4 can also be arranged on the device main body 1 toward the inner side of the wearing part surrounded by the strap 2 and the device main body 1 to sense pressure, which is not limited in the present application. In the embodiments shown in FIG. 2 and FIG. 3 , the fixation is realized through the contraction and expansion of the strap 2 , and the pressure on the strap 2 is most directly sensed and more accurate. When in use, the set value of the second preset value of the control motor can be the average value sensed by several pressure sensors 4, or the set value can be an interval range value, and the pressure sensed by several pressure sensors 4 is averaged.

可选地，头戴显示设备还包括控制开关，控制开关分别与接近传感器3和压力传感器4电连接，控制接近传感器3和压力传感器4。本领域技术人员可以理解，头戴显示设备内通常是具有处理模块的，用于处理电连接的逻辑关系，控制开关也是和该处理模块进行电连接的。控制开关通常可以采用按钮形式，可以设置在设备主体1上。按压控制开关，激活控制开关，可以是调整压力传感器4上的第二预设值的设定，由设定值变更为初始值或小于初始值的数值，那么电机6就会被控制反向转动，驱动绑带2相对于设备主体1扩张，使得头戴显示设备松脱使用者，解除头戴显示设备与使用者的固定关系。还可以是使得接近传感器3被关闭，例如给接近传感器3断电，停止其工作，降低逻辑混乱的风险。Optionally, the head-mounted display device further includes a control switch, which is electrically connected to the proximity sensor 3 and the pressure sensor 4 respectively, and controls the proximity sensor 3 and the pressure sensor 4 . Those skilled in the art can understand that the head-mounted display device usually has a processing module for processing the logic relationship of the electrical connection, and the control switch is also electrically connected with the processing module. The control switch can usually be in the form of a button and can be arranged on the main body 1 of the device. Press the control switch to activate the control switch, which can be to adjust the setting of the second preset value on the pressure sensor 4. If the set value is changed to the initial value or a value smaller than the initial value, then the motor 6 will be controlled to rotate in reverse , the strap 2 is driven to expand relative to the device main body 1, so that the head-mounted display device is released from the user, and the fixed relationship between the head-mounted display device and the user is released.

可选地，头戴显示设备上还包括第一传感器。所述第一传感器与所述电机6电连接。所述第一传感器用于感应绑带的位置和/或状态，绑带2相对于设备主体1的收缩和扩张不可能是无限制的，必然会存在绑带2相对于设备主体1的最小状态和最大状态，当第一传感器感应到绑带2相对于设备主体1收缩至最小状态时，电机6停止转动，或反向转动驱动绑带2相对于设备主体1扩张，直至脱离最小状态，防止堵转的情况发生，脱离最小状态后，电机6是继续转动还是停止转动，本领域技术人员可以实际控制的需要进行设定，本申请对此并不限制；进一步地，当第一传感器感应到绑带2相对于设备主体1扩张至最大状态时，电机6停止转动，或正向转动驱动绑带2相对于设备主体1收缩，直至脱离最大状态，也是可以的。通过第一传感器感应绑带的位置和/或状态，并对电机6加以控制，能够保障设备的良好运行，防止电机6堵转，发生损坏故障。另一方面，能够使得头戴显示设备的绑带调节更加自动化，完善控制逻辑。Optionally, the head-mounted display device further includes a first sensor. The first sensor is electrically connected with the motor 6 . The first sensor is used to sense the position and/or state of the strap. The contraction and expansion of the strap 2 relative to the device body 1 cannot be unlimited, and there must be a minimum state of the strap 2 relative to the device body 1 and the maximum state, when the first sensor senses that the strap 2 shrinks to the minimum state relative to the device body 1, the motor 6 stops rotating, or reversely rotates to drive the strap 2 to expand relative to the device body 1 until it leaves the minimum state, preventing In the case of a stalled rotor, after leaving the minimum state, whether the motor 6 continues to rotate or stops, those skilled in the art can set it according to the needs of actual control, and the present application does not limit this; further, when the first sensor senses When the strap 2 expands to the maximum state relative to the device body 1, the motor 6 stops rotating, or drives the strap 2 to shrink relative to the device body 1 by forward rotation until it leaves the maximum state. Sensing the position and/or state of the strap through the first sensor and controlling the motor 6 can ensure the good operation of the equipment and prevent the motor 6 from being blocked and damaged. On the other hand, it can make the strap adjustment of the head-mounted display device more automatic and improve the control logic.
例如，在发生误操作时，意外触发接近传感器3，电机6开始正向转动，但此时使用者并未佩戴设备，压力传感器4感应到的压力值始终为0，电机6也就不会停止转动，那么当绑带2相对于设备主体1收缩至最小状态时，触发第一传感器，电机6停止转动，就能防止电机6继续正向转动发生堵转；或者是触发第一传感器后，设备判定此时为误操作，切断接近传感器3和压力传感器4分别与电机6的连锁关系，即电连接关系，控制电机6反向转动，脱离最小状态，解除对第一传感器的触发后停止，直至接近传感器3解除感应后再重新恢复其对电机6的联锁控制；还可以进一步的控制电机6继续反向转动，使得绑带2处于最大状态后停止，便于下一次佩戴者能够直接使用，不需要在对绑带2进行调节。For example, when a misoperation occurs, the proximity sensor 3 is accidentally triggered, and the motor 6 starts to rotate forward, but at this time the user is not wearing the device, the pressure value sensed by the pressure sensor 4 is always 0, and the motor 6 will not stop Rotate, then when the strap 2 shrinks to the minimum state relative to the device main body 1, the first sensor is triggered, and the motor 6 stops rotating, which can prevent the motor 6 from continuing to rotate forward and stall; or after the first sensor is triggered, the device Judging that this is a misoperation, cut off the interlocking relationship between the proximity sensor 3 and the pressure sensor 4 and the motor 6 respectively, that is, the electrical connection relationship, control the motor 6 to rotate in the opposite direction, break away from the minimum state, and stop after triggering the first sensor until After the proximity sensor 3 releases the induction, it resumes its interlock control to the motor 6 again; the motor 6 can also be further controlled to continue to rotate in the opposite direction, so that the strap 2 stops after being in the maximum state, so that the wearer can use it directly next time. Strap 2 needs to be adjusted.
进一步地，还可以使得控制开关与第一传感器电连接。例如，当激活控制开关后，第二预设值变更为小于初始值的数值，就能够控制绑带2相对于设备主体1扩张至最大状态时停止，便于不同的使用者使用，当然，本领域将技术人员可以理解，这只是本实用新型的一种使用方法，并不是对其的具体限定。Further, the control switch may also be electrically connected to the first sensor. For example, when the control switch is activated and the second preset value is changed to a value smaller than the initial value, it can be controlled to stop when the strap 2 expands to the maximum state relative to the device main body 1, which is convenient for different users. Those skilled in the art can understand that this is only a method of using the utility model, not a specific limitation thereof.

根据本实用新型的另一个方面，还提供一种新的头戴显示设备的绑带调节方法，包括以下步骤：According to another aspect of the present invention, a new method for adjusting the strap of a head-mounted display device is provided, including the following steps:
使用上述的头戴显示设备；use of the head-mounted display device described above;
在使用时，当接近传感器3探测到与物体之间的距离小或等于第一预设值时，电机6正向转动，驱动绑带2相对于设备主体1收缩。When in use, when the proximity sensor 3 detects that the distance between the object and the object is small or equal to the first preset value, the motor 6 rotates forward to drive the strap 2 to shrink relative to the device main body 1 .
当压力传感器4感应到的压力值等于设定的第二预设值时，电机6停止工作，完成佩戴。When the pressure value sensed by the pressure sensor 4 is equal to the set second preset value, the motor 6 stops working, and the wearing is completed.
进一步地，当压力传感器4感应到的压力值大于第二预设值时，电机6反向转动，驱动绑带2相对于设备主体1扩张。绑带2的扩张直至压力传感器4感应到的压力值等于第二预设值或扩张至绑带2的最大状态时停止。使得在使用者不使用时，通过调整第二预设值的大小来扩张绑带2解除头戴显示设备与使用者之间的固定关系。Further, when the pressure value sensed by the pressure sensor 4 is greater than the second preset value, the motor 6 rotates in reverse to drive the strap 2 to expand relative to the device main body 1 . The expansion of the bandage 2 stops until the pressure value sensed by the pressure sensor 4 is equal to the second preset value or expands to the maximum state of the bandage 2 . So that when the user is not in use, the fixed relationship between the head-mounted display device and the user is released by adjusting the size of the second preset value to expand the strap 2 .
可选地，使用的头戴显示设备还包括分别与接近传感器3和压力传感器4电连接的控制开关，能够控制接近传感器3和压力传感器4。头戴显示设备的绑带调节方法还包括以下步骤：Optionally, the head-mounted display device used further includes control switches electrically connected to the proximity sensor 3 and the pressure sensor 4 , capable of controlling the proximity sensor 3 and the pressure sensor 4 . The method for adjusting the straps of the head-mounted display device also includes the following steps:
激活控制开关，调整压力传感器4上的第二预设值的设定，由设定值变更为初始值或小于初始值，使得使用者能够解除佩戴。Activate the control switch, adjust the setting of the second preset value on the pressure sensor 4, change from the set value to the initial value or less than the initial value, so that the user can release the wearing.
在解除佩戴后，可以通过关闭控制开关，再次调整压力传感器4上的第二预设值的设定，由初始值或小于初始值的数值变更为设定值，为下一次的使用做准备。或者是延迟自定义时间，这个时间可以进行自行设定，例如使用者解除佩戴需要30s，那么就可以自定义45s后压力传感器4上的第二预设值自动由初始值或小于初始值的数值变更为设定值，自动为下一次的使用做准备也是可以的，本申请对此并不限制，能够实现调整控制第二预设值的变化即可。进一步地，为了减少出现控制逻辑混乱及自动控制误操作的可能，我们可以在激活控制开关后，控制接近传感器3关闭；而在控制开关关闭后，控制接近传感器3被重新打开。After unwearing, the setting of the second preset value on the pressure sensor 4 can be adjusted again by turning off the control switch, and the initial value or a value smaller than the initial value can be changed to the set value to prepare for the next use. Or delay the custom time, this time can be set by yourself, for example, it takes 30s for the user to unwear, then you can customize the second preset value on the pressure sensor 4 after 45s to automatically change from the initial value or a value smaller than the initial value It is also possible to change to a set value and automatically prepare for the next use. This application is not limited to this, as long as the change of the second preset value can be adjusted and controlled. Further, in order to reduce the possibility of control logic confusion and automatic control misoperation, we can control the proximity sensor 3 to turn off after the control switch is activated; and control the proximity sensor 3 to be turned on again after the control switch is turned off.
可选地，在发生误操作，不需要佩戴使用的情况下，意外触发接近感应器3，还包括以下步骤：Optionally, accidentally triggering the proximity sensor 3 in the event of a misoperation that does not need to be worn and used may also include the following steps:
压力传感器4感应到的压力值在预设时间内始终未发生变化或变化速率小于第三预设值(正常的经过有限次实验确定的变化速率范围值)时，电机6反向转动驱动绑带2相对于设备主体1扩张至最大状态或触发接近感应器3时绑带2所处的位置时停止，等待下一次操作。When the pressure value sensed by the pressure sensor 4 has not changed within the preset time or the rate of change is less than the third preset value (the normal range value of the rate of change determined after a limited number of experiments), the motor 6 reversely rotates to drive the strap 2 Stop when expanding to the maximum state relative to the main body 1 of the device or the position where the strap 2 is when the proximity sensor 3 is triggered, and wait for the next operation.
或电机6停止转动，等待使用者的进一步操作。例如，激活控制开关(确定是人为操作)，第二预设值变更为小于初始值的数值，电机6反向转动驱动绑带2相对于设备主体1扩张至最大状态或触发接近感应器3时绑带2所处的位置时停止，等待关闭控制开关。Or the motor 6 stops rotating, waiting for further operation of the user. For example, when the control switch is activated (it is determined to be a human operation), the second preset value is changed to a value smaller than the initial value, and the motor 6 rotates in reverse to drive the strap 2 to expand to the maximum state relative to the device main body 1 or trigger the proximity sensor 3 Stop when strap 2 is at the position, waiting to close the control switch.
可选地，接近传感器3和压力传感器4分别与电机6电连接，压力传感器4的优先级高于接近传感器3的优先级。Optionally, the proximity sensor 3 and the pressure sensor 4 are electrically connected to the motor 6 respectively, and the priority of the pressure sensor 4 is higher than that of the proximity sensor 3 .
通过本实用新型提供的头戴显示设备的绑带调节方法，能够使得本实用新型的头戴显示设备的佩戴与解除完全实现自动化，简化操作固定步骤，提高用户体验。Through the strap adjustment method of the head-mounted display device provided by the present invention, the wearing and releasing of the head-mounted display device of the present invention can be fully automated, the operation and fixing steps can be simplified, and user experience can be improved.
