Description

带有平衡杆的按键及手控器 【技术领域】
本发明涉及按键装置技术领域，具体涉及带有平衡杆的按键及手控器。
【背景技术】
以往的带有平衡杆的按键直按式键帽均比较小，限位大都依靠外形，并且为了满足轻薄化要求，整体厚度比较薄，使得键帽导向较短，操作起来键帽四向晃动，手感差，同时部分偏大键帽只有在按压中间区域才能触发功能，按压边缘区域手感较差，且功能触发不良，更有甚者，按压边缘区域还会出现卡滞现象，导致整体操作体验感不佳。
【发明内容】
本发明的目的在于公开带有平衡杆的按键，以至少部分地解决上述问题。
为解决上述技术问题，本发明采用如下技术方案：
带有平衡杆的按键，包括壳体、设于所述壳体上的键帽，所述键帽下方设有至少两组安装筋位，安装筋位上设有安装孔，所述键帽上设有平衡杆，所述平衡杆包括杆部、末端部和连接所述杆部与末端部的连接部，所述杆部穿入所述安装孔并能在安装孔中转动和在键帽按压方向移动，所述壳体上设有定位件，用于定位所述末端部。
采用本方案的有益效果：
本方案中在键帽下方设置平衡杆，平衡杆的刚性特征，使其传力过程更加直接，可以将力传送至整个键帽，因此按压键帽的任意位置，整个键帽都会同步运动，并很好地触发弹性轻触开关，即便触发键帽边缘位置，也会轻盈顺畅，不会出现晦涩或卡滞现象，极大减小了键帽晃动量，并且对于键帽外形尺寸的局限性大大减小，可满足工业设计对于造型的多样性设计。
本方案中键帽与平衡杆杆部轴孔配合，且杆部能在安装孔中转动，按压键帽时，键帽受力向下运动，平衡杆杆部跟随键帽向下运动，末端部被定位件定 位，当平衡杆杆部随着键帽动作时可以保持末端部在键帽按压方向的位置不变，由于末端部无法跟随杆部一起向下运动，因此杆部向下运动的同时，还以自身的轴心线为转动中心转动；杆部贯穿安装孔，在安装孔内壁的作用下杆部不容易出现弯曲，因此按压键帽的任意位置，都可以通过杆部的带动下使整个键帽平稳活动，不会出现晃动或一侧高一侧低的情况，提高了键帽的稳定性；同时，由于定位件、安装孔对平衡杆具有支撑作用，键帽回弹时需要的弹力更小，弹性轻触开关更容易带动键帽回弹。
键帽运动过程中，平衡杆杆部与安装孔孔壁之间的接触为弧面接触，平衡杆末端部与滑槽为线面接触，运动过程中接触面少，滑动摩擦小，按压及回弹时不会因为摩擦而产生阻尼感，按压更加顺畅，提升用户手感。
作为优选，所述安装筋位包括第一安装筋位和第二安装筋位，所述第一安装筋位和第二安装筋位上分别开设开口相对的U形槽和L形槽，所述U形槽和L形槽围成安装孔，所述安装孔的轴向尺寸大于所述杆部的杆径。
作为优选，所述定位件包括滑槽，所述末端部位于所述滑槽中并能在所述滑槽中平移。
作为优选，所述壳体上设有成对径向筋位，成对径向筋位之间形成所述滑槽，所述滑槽宽度大于末端部的杆径。
作为优选，所述定位件包括成对设置的弹片，所述末端部被夹持在两片弹片之间。
作为优选，所述上壳体与所述键帽之间设有导向结构。
作为优选，所述导向结构包括配合设置的导向柱和导向槽，所述壳体和键帽其中之一设有所述导向柱，另一个设有所述导向槽。
作为优选，所述导向柱为十字型导向柱，所述导向槽为十字型导向槽。
作为优选，所述上壳体与所述键帽之间设有限位结构，以在所述弹性轻触开关回弹时止挡所述键帽。
作为优选，所述限位结构包括卡槽和插入卡槽且能相对卡槽滑动的卡扣，所述壳体与所述键帽其中之一设有卡槽，另一个设有卡扣，所述卡槽的槽壁与 所述卡扣抵接以止挡键帽。
作为优选，所述壳体包括固定连接的上壳体和下壳体，所述上壳体与所述下壳体插装或通过紧固件连接。

下面结合附图与具体实施方式对本发明的带有平衡杆的按键作进一步详细描述：
参照图1和图2，带有平衡杆的按键，包括：
壳体1，包括固定连接的上壳体101和下壳体102；
键帽6，设在上壳体101上并能相对上壳体101轴向移动；
键帽6具体包括分别设置的第一键帽601、第二键帽602和第三键帽603，第一键帽601位于第二键帽602和第三键帽603外周，第一键帽601的长度等于第二键帽602和第三键帽603长度之和。
为了对第一键帽601的运动进行导向，第二键帽602和第三键帽603向下延伸出导向支架6021，导向支架6021沿第二键帽602和第三键帽603边缘内侧延伸并围成封闭的内腔，内腔中设有按压弹性轻触开关201的柱形结构6015，导向支架6021外壁上设有轴向凹槽60211，上壳体101上设有供导向支架6021穿过的通孔1011，通孔1011周边处延伸出筒状结构1012，筒状结构1012内侧壁上设有与轴向凹槽60211配合的凸块10121，第二键帽602和第三键帽603运动时，凸块10121在轴向凹槽60211中滑动，导向支架6021与筒状结构1012之间设有限制第二键帽602和第三键帽603运行行程的限位结构，具体的，限位结构 包括设在筒状结构1012上的凸起10122和设在导向支架6021上的插槽60212，第二键帽602和第三键帽603运动时，凸起10122在插槽60212中轴向运动，凸起10122下侧面抵接在插槽60212的下槽壁上以形成限制第二键帽602和第三键帽603回弹行程的限位结构。
由于第一键帽601长度大，按压时有效长度短，若采用上述导向槽，导向效果差，晃动量增大，且第一键帽601边缘容易出现卡滞，导致操作体验感不佳。
如图5所示，针对第一键帽601长度大，容易出现卡滞和操作体验感不佳的情况，如图2～图4所示，本方案中在第一键帽601下方设置平衡杆7，具体的，第一键帽601下方设有至少两组安装筋位，至少两组安装筋位位于第一键帽601长度方向的两端，安装筋位上设有安装孔，至少两组安装筋位上的安装孔尺寸相同，且孔中心连线与第一键帽601平行。
如图8所示，平衡杆7具体包括杆部701、两个末端部703和两个连接杆部701与末端部703的连接部702，如图4所示，杆部701穿入安装孔并能在安装孔中转动，上壳体101上设有定位件，用于定位末端部703，以保持末端部703在第一键帽601按压方向上的位置不发生变化。
作为优选的，如图6所示，定位件包括滑槽1018，滑槽1018至少为两个，两个滑槽1018的高度相同，且两个滑槽1018的上槽壁的连线与第一键帽601平行，两个滑槽1018的下槽壁的连线也与第一键帽601平行。如图4所示，安装筋位与滑槽1018在第一键帽601上的投影位于第一键帽601宽度方向的两侧。
在第一键帽601下方设置平衡杆7，平衡杆7的刚性特征，使其传力过程更加直接，可以将力传送至整个第一键帽601，因此按压第一键帽601的任意位置，整个第一键帽601都会同步运动，即便按压第一键帽601边缘位置，也不会出现晦涩或卡滞现象。
本方案中第一键帽601与平衡杆7杆部701轴孔配合，且杆部701能在安装孔中转动，末端部703位于滑槽1018中，滑槽1018的上壁和下壁能止挡末端部703在第一键帽601按压方向上运动，只能在滑槽1018中平移，按压第一键帽601时，第一键帽601受力向下运动，平衡杆7杆部701跟随第一键帽601向下运动，由于末端部703无法跟随杆部701一起向下运动，因此杆部701向下运动 的同时，还以杆部701自身的轴心线为转动中心转动，杆部701贯穿安装孔，在安装孔内壁的作用下杆部701不容易出现弯曲，因此按压第一键帽601的任意位置，都可以通过杆部701带动下使整个第一键帽601平稳活动，不会出现晃动或一侧高一侧低的情况，提高了稳定性；同时，由于滑槽1018、安装孔对平衡杆具有支撑作用，第一键帽601回弹时需要的弹力更小，弹性轻触开关更容易带动第一键帽601回弹。
此外如图7所示，定位件还可以为成对设置的弹片1019，上壳体101上设有两组弹片1019，每组弹片1019都包括两片，平衡杆7的末端部703被夹持在两片弹片1019之间，以保持末端部703在第一键帽601按压方向的位置不变，且不会影响到末端部703的转动。
第一键帽601运动过程中，平衡杆7杆部701与安装孔孔壁之间为弧面接触，平衡杆7末端部703与滑槽1018为线面接触，运动过程中接触面少，滑动摩擦小，按压及回弹时不会因为摩擦而产生阻尼感，按压更加顺畅，提升用户手感。
为了便于平衡杆7杆部701的安装，如图4和图5所示，安装筋位包括间隔设置的第一安装筋位6011和第二安装筋位6012，第一安装筋位6011和第二安装筋位6012穿入上壳体101的下方，第一安装筋位6011和第二安装筋位6012位于上壳体101下方的部分上分别开设开口相对的U形槽60121和L形槽60111，具体的，U形槽60121由第一安装筋位6011侧面向内延伸开设，L形槽60111由第二安装筋位6012底端向内延伸开设，U形槽60121和L形槽60111围成安装孔，安装孔的轴向尺寸略大于杆部701的杆径，安装时，杆部701顺着L形槽60111滑动并慢慢卡入U形槽60121中，L形槽60111对U形槽60121槽口起到阻挡作用，防止杆部701转动时从U形槽60121中脱出。
上壳体101上设有至少两组成对径向筋位，如图3、图4和图6所示，成对径向筋位包括设在上壳体101上的第一径向筋位1013和由位于上壳体101下方的筒状结构1012外侧壁向外延伸出的第二径向筋位1014，第一径向筋位1013和第二径向筋位1014沿轴向设置，其之间形成滑槽1018，滑槽1018宽度略大于末端部703的杆径，通过第一径向筋位1013和第二径向筋位1014的限位，末端部703只能在滑槽1018中径向左右滑动，不能轴向上下移动，至少两组成对径向筋位的第一径向筋位1013的下侧面的连线与上壳体101平行，至少两组成对 径向筋位的第二径向筋位1014的上侧面的连线与上壳体101平行，从而至少两组成对径向筋位形成的滑槽1018的高度相同，滑槽1018中心轴线的连线与上壳体101平行。
上述安装孔和滑槽1018的设置，使平衡杆7的两个末端部703的轴线位于同一水平面，杆部701的两侧也位于同一水平面，且由于平衡杆7的刚性属性，平衡杆7的中心对称面两侧的各对称点的运动始终保持同步，即当按压第一键帽601任意边缘时，第一键帽601带动按压侧的平衡杆7向下运动，此时由于平衡杆7的刚性，按压侧的平衡杆7带动另一侧的平衡杆7同步运动，另一侧的平衡杆7又带动同侧的第一键帽601向下运动，使得整个第一键帽601均可同步运动。
为了对第一键帽601的运动进行导向，如图4～图6所示，上壳体101与第一键帽601之间设有导向结构，导向结构包括配合设置的导向柱和导向槽，第一键帽601上设有导向柱，上壳体101上设有与导向柱间隙配合的导向槽，导向柱在导向槽中轴向移动，优选地，导向柱为十字型导向柱6013，导向槽为十字型导向槽1015，上述十字型导向柱6013和十字型导向槽1015的配合结构，在导向的同时，对第一键帽601还起到周向和径向限位作用，防止第一键帽601转动或偏移。
为了进一步提高导向和限位效果，第一键帽601下方设有至少两个导向结构，至少两个导向结构沿第一键帽601长度方向间隔分布。
当然，在其他实施例中，也可以在第一键帽601上设置导向槽，上壳体101上设置与导向槽配合的导向柱。
平衡杆7的设置使第一键帽601整体可以同步运动，同时由于安装孔的轴向尺寸略大于杆部701的杆径，滑槽1018宽度略大于末端部703的杆径，平衡杆7与第一键帽601和上壳体101的装配间隙极小，结合十字型导向柱6013和十字型导向槽1015的小间隙的导向配合结构，使第一键帽601运动过程中，对第一键帽601的轴向和周向限位比较充分，配合平衡杆7的平衡稳定性，第一键帽601按压时不会侧翻，极大程度上保证了第一键帽601及稳定性，降低了晃动量。
进一步的，平衡杆7的末端部703与连接部702的夹角α设计为直角或钝角， 优选90°≤α≤120°，使得在按压第一键帽601时，末端部703始终处于第一径向筋位1013和第二径向筋位1014之间，且保持与其中一条筋位接触，可防止平衡杆7与壳体1脱离或回弹时引起的震动，也可避免平衡杆7与壳体1之间的碰撞而产生噪音，从而有效提升使用体验。
第一键帽601下方设有按压轻触开关的柱形结构6015，按压第一键帽601，第一键帽601带动柱形结构6015向下挤压弹性轻触开关201，弹性轻触开关201接通，松手后，弹性轻触开关201回弹，向上顶起柱形结构6015，柱形结构6015带动第一键帽601向上回弹，为了限制第一键帽601的回弹行程，如图4～图6所示，上壳体101与第一键帽601之间设有限位结构，具体的，上壳体101的十字型导向槽1015上设有卡扣10151，第一键帽601下方向下延伸出卡接件6014，卡接件6014上开设卡槽60141，卡槽60141较大，卡扣10151能在卡槽60141中轴向移动，第一键帽601向上回弹至最大位移处，卡槽60141的槽壁与卡扣10151抵接形成限位结构。
本实施例中上壳体101和下壳体102的固定连接方式包括插装和/或紧固件连接，两种方式可以单独使用，也可以同时使用，具体的，插装方式为，如图2和图4所示，下壳体102包括侧壁，侧壁上设有卡块1021，上壳体101设有安装耳1016，安装耳1016上设有安装槽10161，装配时，用力推上壳体101和下壳体102，使其产生相对运动，从而将卡块1021卡入安装槽10161中实现上壳体101与下壳体102的插装；紧固件连接方式为，如图3所示，紧固件包括自攻螺钉8，下壳体102上设有螺纹穿孔1022，上壳体101上设有螺纹固定孔1017，自攻螺钉8螺动穿过螺纹穿孔1022后固定在螺纹固定孔1017中。
参照图1至图8，本发明还公开了手控器，手控器包括上述中公开的带有平衡杆的按键，其中手控器包括外壳和键帽，外壳为带有平衡杆的按键的壳体1，键帽为带有平衡杆的按键的键帽6，以实现手控器的功能，控制物体的运动状态和运动模式，手控器中设置了带有弹性轻触开关201的电路板2，按压键帽6接通弹性轻触开关201，电路板2设在上壳体101和下壳体102之间，电路板2上设有用于连接电源线的线卡3，上壳体101上还设有面镜4，第二键帽602和第三键帽603位于面镜4外周并沿面镜4外周并列排布，上壳体101上设有两组键帽6，两组键帽6相对面镜4对称设置。
手控器的装配过程如下：
(1)先将线卡3接插在PCB组件上，组成PCB总成；
(2)将PCB总成装入下壳体102；
(3)将面镜4贴在支架上，然后将支架安装在上壳体101；
(4)将第一键帽601、第二键帽602及第三键帽603分别安装在上壳体101；
(5)将平衡杆7与第一键帽601及上壳连接，然后将上壳与下壳装配好，最后用螺钉将上壳体101及下壳体102固定。
以上实施例仅作为实例，不对本发明的范围起到限定作用。本领域技术人员在此基础上，可以在本发明权利要求的保护范围内，预想到能实现相同功能的其他实施方式。
