 本发明的实施方式
为了更清楚地表述本发明，下面结合附图对本发明作进一步地描述。
请参阅图1-图4，本发明的具有信号屏蔽功能的被动式遥控钥匙包，包括用于容纳被动式遥控钥匙的屏蔽壳体1，屏蔽壳体1的内壁设有金属电镀层，使得被动式遥控钥匙的信号与外界进行屏蔽，将被动式遥控钥匙保护起来，而在现有技术中，使用时，需要将屏蔽壳体1打开或者需要将被动式钥匙取出，这样使用不便，且屏蔽壳体1可打开的位置存在一定的泄露信号的风险，因此在屏蔽壳体1的一内壁上设有接收天线2，与内壁相对的外壁上设有发射天线4，发射天线4上具有连续且不在一条直线上的镂空部，且发射天线4由镂空部围合而成的部分为弹片部41，弹片部4悬空的一端设有弹簧探在针3，而屏蔽壳体1设有供弹簧弹针3穿过的通孔，在接收天线2对应该弹簧探针3的位置上镀有触点；发射天线2的上方设有沿弹片部41滑动的推动部5，推动部5上设有抵压在弹片部41上的凸块51；由于弹片部41的一端与发射天线4连接，而另一端悬空，因此弹片部41的不同位置承受压力的能力是不同的，也就是抗变形的能力是不同的，靠近连接发射天线4的一端承受压力的能力最强，而悬空的的一端承受压力的能力最弱，因此，当推动部5的凸块51抵压弹片部41靠近连接发射天线4的一端时，弹片部41发生的变形很小，此时弹簧探针3与接收天线2的触点分离，且正好位于接收天线3的触点上空，而推动推动部5沿靠近弹片5部悬空的一端运动时，凸块51随推动部5抵压在弹片部4沿靠近悬空的一端的的位置上，弹簧部41承受压力的能力越来越弱，当凸块51滑动到正好抵压在弹簧部41悬空的一端时，弹片部41的变形程度达到最大，同时弹簧弹针3正好顶在接收天线2的触点上，实现信号的导通，使得汽车的信号通过接收天线2进行接收，然后通过发射天线4发出启动信号到汽车上，实现对汽车的遥控控制；完成后，而只需要反推推动部5沿弹片部41远离悬空一端的方向运动，弹片部41承受压力的能力越来越强并逐渐恢复原形，当凸块51滑动到正好抵压在弹簧部41连接发射天线2的一端时，弹片部41的完全恢复原形，同时弹簧弹针3完全远离接收天线2的触点上信号的阻断，将信号进行屏蔽，使用方便，且良好了避免钥匙内的信息被盗取及误开启汽车。
在本实施例中，而为了保证弹片部41具有足够的变形空间，将镂空部设置为U字型，且镂空部的沿着发射天线4的长度方向设置，这样弹片部41具有一定的长度，使得用户在使用时，可以保证推动部5运动的距离，而令用户可以准确地判断屏蔽信号和接通信号的位置；且凸块51为斜梯型，且凸块51的顶部正好抵压在弹片部41上。
在本实施例中，参阅图2-图3，为了方便被动式钥匙的放置，屏蔽壳体1包括上壳体12和下壳体13，上壳体12和下壳体13的外壁也设有金属电镀层11，即上壳体12和下壳体13的所有表面都设有金属电镀层，当上壳体12和下壳体13接触时，上壳体12的两侧设有卡槽121，下壳体的两侧设有与卡槽121适配卡扣131，这样在将被动式遥控钥匙放置在上壳体12上，且将下壳体13通过卡扣131卡入卡槽121中，即可实现上壳体12和下壳体13的相互固定，且将被动式遥控钥匙的信号完全屏蔽，而需要使用时，只需推动推动部5至凸块51抵压在弹片部41的悬空部的一端上即可，使用方便，且良好了避免钥匙内的信息被盗取及误开启汽车。
在本实施例中，继续参阅图2-图4，为了保证上壳体12和下壳体13连接的严密性，上壳体12可以设置为上壳体12的开口直径大于下壳体13的开口直径，且上壳体12的内设有凸台122，而下壳体13的边缘正好抵持在凸台122上，这样只要将下壳体13通过卡扣131卡入卡槽121中，下壳体13的边缘完全与上壳体12的内壁接触，良好地保证上壳体12和下壳体13之间连接的严密性；上壳体12还可以设置为上壳体12的开口边缘设有唇部123，且卡槽121设在唇部123对称的两侧上，而下壳体正好卡入唇部123内，将下壳体13通过卡扣131卡入卡槽121中，不仅下壳体13的开口边缘与上壳体12接触，下壳体13位于唇部123内的部分均与上壳体12接触，大大增大了下壳体13与上壳体12的接触面积，两者完全闭合，且下壳体13与上壳体12接触的部分始终为金属电镀层，良好地避免了信号的泄露；而为了防止在使用过程中，上壳体12和下壳体13的金属电镀层11容易受到外界的摩擦或割划，导致金属电镀层11掉落或者缺失，因此还设置有硅胶套6，由于硅胶具有一定的可变性，只需要在将上壳体12和下壳体13相互闭合后，从屏蔽壳体的一端套入即可，起到保护上壳体12和下壳体13的金属电镀层11的作用，保证该被动式遥控钥匙包的使用寿命。
在本实施例中，参阅图3-图7，为了方便发射天线4的固定，还包括固定在与屏蔽壳体1设有接收天线2的内壁相对的外壁上的固定部7，固定部7远离屏蔽壳体1的一面设有容置发射天线4的容置部，且容置部的两端设有用于卡住发射天线4的突出部71，容置部的中部为镂空，使得发射天线4上的弹簧探针3可以穿过屏蔽壳体1的通孔，从而进入屏蔽壳体1内，同时又可以将发射天线4进行良好的固定，而为了保证屏蔽壳体1的屏蔽能力，固定部7的对称的两端上设有固定孔72，而在屏蔽壳体1对应的位置上设有供固定孔72穿过的固定柱14，进而将发射天线4固定在屏蔽壳体1上，同时又保留了屏蔽壳体1的屏蔽能力；还可以在固定部7远离屏蔽壳体1的一面边缘设有凸缘74，推动部5的两侧向同一方向延伸设有正好滑动卡合在凸缘74上的第二回勾部52，进而将推动部5滑动固定在固定部7上，同时推动部正好抵持在固定柱73，进一步加强发射天线4固定在屏蔽壳体1上的稳定性；而接收天线2固定在屏蔽壳体1上的方式可以为，在下壳体13的内壁上设有延伸块132，通过延伸块132将接收天线2夹持固定在屏蔽壳体1上。
 工业实用性
本发明的优势在于：
（1）设有屏蔽壳体，且在屏蔽壳体上滑动设有推动部，在推动部设有凸块，且在发射天线的部分设有一端悬空的弹片部，使得推动推动部沿靠近或远离弹片部悬空的一端运动，控制凸块抵压在弹片部的不同位置上，改变弹片部的变形程度，进而弹簧弹针正好与接收天线的触点接触或分离，进而选择是否发射信号或接收外界信号，使用方便，且良好了避免钥匙内的信息被盗取及误开启汽车；
（2）将下壳体的开口直径小于上壳体的开口直径，且上壳体和下壳体的所有表面均设有金属电镀层，且下壳体的开口边缘抵持在上壳体的内壁凸缘上，使得下壳体与上壳体接触的部分始终有金属电镀层，防止信号的泄露。
