本申请属于通信技术领域，具体涉及一种电子设备。The present application belongs to the technical field of communication, and specifically relates to an electronic device.
背景技术Background technique
目前，为了实现更大区域的显示、更广的视角、更高的握持贴合度，曲面屏越来越广泛地应用于手机产品之中。但是由于曲面屏屏幕存在较大弧度，非常不利于贴保护膜。为了使保护膜更容易附着在曲面之上，现在的曲面屏保护膜多使用UV胶固化粘接。在使用过程中，UV胶(紫外光固化胶)会顺着主板上盖和侧按键之间的间隙进去手机内部。At present, in order to achieve larger area display, wider viewing angle, and higher grip fit, curved screens are more and more widely used in mobile phone products. However, due to the large curvature of the curved screen, it is very unfavorable to attach a protective film. In order to make the protective film easier to attach to the curved surface, the current curved screen protective film mostly uses UV glue to cure and bond. During use, UV glue (ultraviolet light curing glue) will enter the interior of the phone along the gap between the motherboard cover and the side buttons.
TPU(热塑性聚氨酯弹性体橡胶)弹性较强可大幅度变形，能有效容差结构件装配公差，同时TPU在受到冲击后不会产生塑性变形，能保证按键手感不会因为跌落冲击而减弱，其作为一种超弹性材料，按键凸台广泛采用TPU材料。但是UV胶以及其他许多有机溶剂均可腐蚀TPU，导致曲面屏手机的按键失效率急剧上升。如何解决在贴曲面屏保护膜时，UV胶及其他有机溶剂腐蚀按键凸台是急需解决的问题。TPU (thermoplastic polyurethane elastomer rubber) has strong elasticity and can be greatly deformed, which can effectively tolerate the assembly tolerance of structural parts. At the same time, TPU will not produce plastic deformation after being impacted, which can ensure that the button feel will not be weakened by the impact of falling. As a super-elastic material, TPU material is widely used in button bosses. However, UV glue and many other organic solvents can corrode TPU, resulting in a sharp increase in the key failure rate of curved screen phones. How to solve the problem that UV glue and other organic solvents corrode the button bosses when attaching the curved screen protective film is an urgent problem to be solved.
此外，由于按键高出整机侧面，当手机按键所在侧面受到冲击时，整个手机的冲击力会直接作用于侧按键，侧按键所受的力又直接传递给按键凸台和锅仔片，导致按键凸台产生形变，如果按键凸台产生不可恢复的变形，按键凸台将和锅仔片脱离接触，导致按压手感减弱，反应不够灵敏。In addition, because the buttons are higher than the side of the whole machine, when the side where the buttons of the mobile phone are located is impacted, the impact force of the entire phone will directly act on the side buttons, and the force on the side buttons will be directly transmitted to the button bosses and metal domes, resulting in The button boss is deformed. If the button boss produces irreversible deformation, the button boss will be out of contact with the dome, resulting in weakened pressing feel and insufficient responsiveness.

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的电子设备进行详细地说明。The electronic device provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.
请参考图1和图2，图1为现有技术中的按键凸台与锅仔片的位置关系示意图，图2为现有技术中按键与曲面屏的位置关系示意图。如图1和图2所示，锅仔片11设置在主板上，主板上盖12覆盖主板，按键14上的按键凸台13与锅仔片11正对设置，按键凸台13采用TPU制作。由于按键14高出整机侧面，当按键14所在的手机侧面受到冲击时，整个手机的冲击力会直接作用于按键14，按键14所受的力又直接传递给按键凸台13和锅仔片11，导致按键凸台13产生形变。如果按键凸台13产生不可恢复的变形，按键凸台13和锅仔片14之间就会脱离接触，导致手感减弱，严重时甚至会导致按键功能失灵。如图2所示，在手机采用曲面屏15时，主板上盖12与曲面屏15之间圆滑过渡，但是为了能把按键14按压下去，按键14在侧面要高处于曲面屏，不可避免的，主板上盖12与按键14之间会存在缝隙16，当采用UV胶涂覆保护膜时，UV胶将会沿着曲面屏15的曲面以及主板上盖12的侧面流到按键14上被其阻挡，并沿着按键14的轮廓进入到内部，最终导致按键凸台13被腐蚀，导致按键失效率显著提升。Please refer to FIG. 1 and FIG. 2 , FIG. 1 is a schematic diagram of the positional relationship between the button boss and the dome in the prior art, and FIG. 2 is a schematic diagram of the positional relationship between the button and the curved screen in the prior art.

FIG. 3 is a schematic diagram of the button structure of an electronic device provided by the embodiment of the present application. FIG. 4 is a schematic structural diagram of the button boss provided by the embodiment of the present application. FIG.

本申请实施例中，顾名思义，PEI凸台33即采用PEI(聚醚酰亚胺)材料制作，从而PEI凸台33可以不被UV胶和大部分有机溶剂腐蚀溶解，可以有效降低按键的失效率。In the embodiment of the present application, as the name suggests, the
本申请的一些实施例中，按键凸台32的材质为铝合金材质，采用铝合金制成的按键凸台32可以防止被UV胶等有机溶剂腐蚀，强度较高，由于在按键凸台32外套设有PEI凸台33，虽然PEI凸台33回弹性能差，但是在按键主体31受到外力冲击时，铝合金的按键凸台32可以承受大部分的力，从而减少PEI凸台33的塑形变形，从而确保按键的手感，而由于按键凸台32仅有圆柱凸台323会与按键触点接触，接触面为平面且面积较小，并且在按键主体31受到外力冲击时，PEI凸台33也会与按键触点接触，PEI凸台33材质较软，可以起到一定的缓冲作用，不会破坏按键触点；由此可知，按键凸台32与PEI凸台33两者相辅相成，既具有良好的耐有机腐蚀的性能，在承受冲击力时也可以减少PEI凸台和按键凸台的变形，从而保证按压手感，延长按键使用寿命。In some embodiments of the present application, the material of the
请参考图8，为本申请实施例提供的PEI凸台的俯视图。如图6至图8所示，PEI凸台33包括第一部331和第二部332，第一部331和第二部332呈一体设置，第一部331固定设置于按键主体31上，第二部332位于第一部331的远离按键主体31的一侧，第一部331和第二部332的内部共同形成用于容置按键凸台32的空腔，PEI凸台33的内壁面与按键凸台32的侧面紧密贴合。其中，第二部332的相对的两个外侧壁3321均向内凹陷，形成月牙形的反补偿形状，在PEI凸台33受到的冲击力过大，按键凸台32受损后，两个外侧壁3321可以补偿PEI凸台33的形变，确保其不会发生过大的形变而导致按键卡死，从而延长了按键的使用寿命。在一些可选的实施方式中，第一部331可以呈椭圆柱状，第二部可以呈长方体状。Please refer to FIG. 8 , which is a top view of the PEI boss provided by the embodiment of the present application. As shown in Figures 6 to 8, the
本申请的一些实施例中，按键凸台32还包括基体，所述基体包括依次设置于按键主体31上的第一基体321和第二基体322，也即第一基体321固定设置在按键主体31上，第二基体322则固定设置在第一基体321的远离按键主体31的一侧，圆柱凸台323则设置于第二基体322的远离第一基体321的一侧，第一基体321和第二基体322均呈长方体状。其中，第二基体322的宽度大于第一基体321的宽度，以形成第一台阶，第二基体322的长度小于第一基体321的长度，以形成第二台阶，通过所述第一台阶和所述第二台阶实现PEI凸台33在圆柱凸台323的轴线上的限位，也就是说，第一台阶可以限制PEI凸台33朝向按键主体31方向移动，第二台阶可以限制PEI凸台33向远离按键主体31的方向移动，从而使按键凸台32和套设在其外的PEI凸台33保持相对位置不变，确保圆柱凸台323一直露出PEI凸台33的远离按键主体31的一侧表面，以实现圆柱凸台323与按键触点的接触，同时也使得圆柱凸台323不会突出于PEI凸台33的远离按键主体31的一侧表面过大，导致受外力冲击时只有圆柱凸台323与按键触点接触，因缺少PEI凸台33的缓冲作用而导致圆柱凸台323和按键触点均受到较大的破坏。In some embodiments of the present application, the
本申请的一些实施例中，第一基体321和第二基体322的中心位于圆柱凸台323的轴线上，从而确保按键主体31受外力使可以径直地使按键凸台32与按键触点接触，避免力矩偏差而导致按键手感不佳，同时保证了按键的寿命。In some embodiments of the present application, the centers of the
本申请的另一些实施例中，第一基体321、第二基体322和圆柱凸台323为一体结构，具体可以是一体成型的铝合金结构件，方便大批量的生产制造。In other embodiments of the present application, the
本申请的一些实施例中，PEI凸台33通过模内注塑工艺形成于按键凸台32外，模内注塑工艺可以使PEI凸台33与按键凸台32之间紧密贴合，确保两者相对位置固定。In some embodiments of the present application, the
如图3所示，在本申请的一些实施例中，按键主体31包括主体部311和凸起部312，凸起部312设置于主体部311的中部区域，按键凸台32即设置于凸起部312的远离主体部311的一侧表面，凸起部312可以缩短按键凸台32与按键触点之间的距离，以减小按键凸台32的厚度。As shown in FIG. 3 , in some embodiments of the present application, the
在本申请的另一些实施例中，按键主体31还包括两个卡扣部313，卡扣部313设置于凸起部312的两侧，同样固定设置在主体部311上，例如主体部311呈长条状，卡扣部313即可以设置在主体部311的两端，卡扣部313用于与所述电子设备的外壳固定连接。In other embodiments of the present application, the
本申请实施例中，所述电子设备还包括主板，所述按键触点与所述主板连接，所述按键触点具体为锅仔片按键，其具有更好的手感、更长的寿命。In the embodiment of the present application, the electronic device further includes a main board, the key contact is connected to the main board, and the key contact is specifically a dome key, which has a better feel and a longer life.
在本申请实施例中，通过将PEI凸台套设在按键凸台外，两者既具有良好的耐有机腐蚀的性能，在承受冲击力时也可以减少PEI凸台和按键凸台的变形，从而保证按压手感，延长按键使用寿命。In the embodiment of the present application, by setting the PEI bosses outside the button bosses, both have good organic corrosion resistance, and can also reduce the deformation of the PEI bosses and the button bosses when subjected to impact force. So as to ensure the pressing feel and prolong the service life of the keys.
