下面结合附图并通过具体实施方式来说明本申请的技术方案。
如图1结合图2和图5所示，本实施例提供了一种按键操作装置，其包括底座1、弹性连接件2和两个按压罩3，底座1上设置有两个沿操作轴线a相互独立的电气开关7；弹性连接件2设置在底座1上，且弹性连接件2包括固定部22和分别与固定部22连接的两个弹性臂21，固定部22设置在弹性臂21的朝向电气开关7的一侧；弹性臂21与电气开关7一一对应，且弹性臂21被配置为对按压罩3提供背向电气开关7的弹力；两个按压罩3分别设置在两个弹性臂21上，且两个按压罩3能分别沿操作轴线a独立摆动，以带动弹性连接件2形变并启动对应的电气开关7。
本申请提供了一种按键操作装置，使用时，只需根据需要对相应的按压罩3施加外力以使其摆动进而启动相对的电气开关7即可，取消施加的外力后，弹 性连接件2的弹性臂21自动复原并带动按压罩3反向摆动远离电气开关7。此外，由于两个按压罩3能独立摆动，故该按键操作装置即可实现对单一电气开关7的启动，也可实现同时对两个电气开关7的启动。该按键操作装置结构简单，能满足单独启动一个电气开关7和同时按动两个电气开关7的需求。
示例性地，电气开关7可为轻触开关，也可为锅仔片或薄膜开关。
本实施例中，为了方便使用者操作，电气开关7、弹性臂21和按压罩3均沿操作轴线a对称设置，即当分别对两个按压罩3施加外力时能使两个按压罩3带动两个弹性臂21分别以操作轴线a为中心逆时针和顺时针摆动，从而启动相对的电气开关7；取消施加的外力时，两个弹性臂21因自身的弹性分别顺时针和逆时针摆动复原，进而使两个相对应的按压罩3也能分别顺时针和逆时针摆动还原以离开电气开关7。当然，在其它实施例，两个电气开关7、弹性臂21和按压罩3也可是非对称设置，本实施例不做限制。
示例性地，为了方便加工，弹性臂21和固定部22为一体成型结构，即弹性连接件2整体为弹片。当然，在其它实施例中，只要能使弹性臂21具有弹力即可，本实施例不做限制。
可选地，固定部22上开设有安装圆柱孔221，且安装圆柱孔22的轴向与操作轴线a重合，以实现弹性连接件2设置在底座1上且保证两个按压罩3能沿操作轴线a分别独立摆动，紧固件11穿设于安装圆柱孔22且紧固件11的两端分别与底座1连接以对弹性连接件2形成定位支承作用。
可以理解的是，由于固定部22设置在弹性臂21的朝向电气开关7的一侧，能提供一定的活动空间以便按压罩3摆动。
示例性地，紧固件11为固定销。
其中，结合图3所示，按压罩3上设置有与电气开关7相对应的凸起31，当按压罩3摆动时凸起31能率先与电气开关7抵接并施加按压力，即通过凸起31实现对电气开关7的准确按压，进而减少按压罩3的摆动幅度，从而提高按键操作装置整体结构的紧凑性。
其中，结合图4所示，按压罩3包括顶板和两个侧板，顶板的顶面和底面分别为操作面301和接触面302，本实施例中凸起31设置在接触面302上。
示例性地，结合图4和图5所示，为了维护方便，按压罩3和弹性臂21其中一个上设置有卡扣32，另一个上设置有能与卡扣32相配合的卡槽211，以使按压罩3与弹性连接件2可拆卸连接。本实施例中，卡扣32设置在接触面302上，卡槽211设置在弹性臂21上。当然，在其它实施例，也可采用其它的可拆卸结构实现按压罩3与弹性连接件2的连接，本实施例不做限制。
可选地，卡扣32设置有导向斜面，以便在拆装按压罩3时能起到导向作用，提高拆装效率。
本实施例中，为了避免仅使用卡扣32与卡槽211配合时弹性连接件2在受压后自身回弹力过大，进而导致按压罩3脱离弹性连接件2，弹性臂21还包括两个沿操作轴线a方向间隔设置的支撑条212，且按压罩3与支撑条212插接，从而对按压罩3起到支撑和固定的作用。当然，在其它实施例中，也可仅使用支撑条212与按压罩3插接，只要能保证弹性连接件2与按压罩3连接稳定即可，本实施例不做限制。
示例性地，为了实现支撑条212与按压罩3插接，两个侧板相对的内壁上设置有凸块33，且凸块33与按压罩3的接触面302之间存在间隙(即凸块33与顶板之间存在间隙)，支撑条212能插接在间隙内。
可选地，按压罩3两个相对的内侧壁上均可间隔设置多个凸块33，以保证保护罩与支撑条212插接稳定。可以理解的是，凸块33的数量和形状可根据按压罩3的内壁形状和实际需求进行设计，本实施例不做限制。
可选地，按压罩3的操作面301为凹面，适配于使用者的手指，符合人体工程学，以便使用者能快速准确地对按压罩3施加外力。
其中，按键操作装置还包括安装件4和两个密封件5，安装件4设置在底座1上，安装件4上设置有两个与电气开关7一一对应的定位槽41；密封件5与电气开关7一一对应，且密封件5罩设在电气开关7外并能封堵定位槽41，按 压罩3摆动时能下压密封件5以启动电气开关7
此外，通过安装件4和密封件5能使电气开关7密封安装在底座1上，尽可能降低外界环境对电气开关7的影响，延长其使用寿命。
可选地，为了使密封件5能与电气开关连接更为紧密，电气开关7的顶端伸出于定位槽41外。
其中，密封件5由弹性材料制成，以保证保护罩向靠近电气开关7方向摆动时凸起31部与密封件5抵接进而使密封件5变形以按压电气开关7，当保护罩反方向摆动远离密封件5后密封件5在自身的回弹力下停止按压电气开关7。
此外，通过在电气开关7外上设置内部中空的密封件5能增强两者安装在一起后的整体弹性，在按压罩3在外力下按压电气开关7时，密封件5受力将发生形变并且为电气开关7提供更有效的缓冲保护。
可选地，按键操作装置还包括两个与电气开关7一一对应的增强件6，增强件6设置在密封件5和电气开关7之间，按压罩3摆动时能下压密封件5并带动增强件6启动电气开关7，即通过增强件6提高按压电气开关7的稳定性，提高了由电气开关7控制的相关电控命令的反馈响应度。
本实施例中，增强件6套设在电气开关7外，密封件5套设在增强件6外，以提供更好地支撑作用。
其中，增强件6的硬度大于电气开关7的硬度，以实现提高反馈响应度。
本实施例还提供了一种电动辅助自行车，其包括车管部和上述的按键操作装置，按键操作装置通过底座1的夹紧部安装在车管部上。
本申请提出一种电动辅助自行车，该电动辅助自行车中的按键操作装置结构简单，能满足单独启动一个电气开关和同时按动两个电气开关的需求。
