Description

遥控器 技术领域
本发明涉及一种遥控器。
背景技术
在现有的无人机遥控中，为了使得遥控的维度更多、遥控的精度更高和提高遥控时的操作手感，一般会采用遥控器进行遥控，通过摇杆来控制遥控器内的电位器。
遥控器的摇杆突出于遥控器面板，这就造成一个问题：当遥控器不慎跌落，且落地时是摇杆首先着地的话，冲击力会通过摇杆传递到电位器，这容易对电位器、电路板或电路板上的电子元件造成损坏，导致遥控器无法正常使用。
发明内容
(一)要解决的技术问题
本发明的目的在于提供一种遥控器，其能够解决在遥控器落地且摇杆首先着地的情况下，电位器、电路板或电路板上电子元件因摇杆所传递的冲击力而容易受损的问题。
(二)技术方案
为了达到上述目的，本发明提供了一种遥控器，包括遥控器本体、设置在遥控器本体内的电位器、以及与电位器相连接的摇杆，摇杆包括供使用者接触的控制端和与控制端相对的连接端，电位器包括电位器本体和从电位器本体突出设置的控制柄，摇杆的连接端与电位器的控制柄连接，在摇杆的连接端与电位器的控制柄之间设置有缓冲结构。
其中，摇杆的连接端的端面设置有容置腔，容置腔从摇杆的连接端的端面朝摇杆的控制端的方向内凹，电位器的控制柄伸入容置腔使电位 器的控制柄至少在周面上受限于摇杆，缓冲结构设置在容置腔之内。该容置腔不但用于放置缓冲结构，同时其还用于使电位器的控制柄在周面上受限于摇杆。
进一步的，摇杆的连接端与电位器的控制柄可拆卸连接。使得摇杆与电位器便于组装，易于生产，制造成本低。
更进一步的，缓冲结构为柱状结构，该柱状结构包括相对的上表面和下表面，上表面抵顶容置腔的顶壁，下表面抵顶控制柄的顶端。在该种结构中，缓冲结构能够吸收从摇杆的轴向方向往控制柄的轴向方向传递的冲击力。
更进一步的，缓冲结构为帽状结构，该帽状结构包裹控制柄的顶端，该帽状结构的顶端和四周均抵顶容置腔的壁面，该帽状结构的顶端和四周具有相同或不同的厚度。在该种结构中，缓冲结构能够吸收从摇杆往控制柄的多个方向传递的冲击力。
其中，摇杆外壁固定地或可拆卸地连接有遮蔽罩，遮蔽罩具有朝向连接端开放的穹顶结构，穹顶结构的开口边缘超过连接端的末端或至少与之平齐，穹顶结构包括与电位器的控制柄配合的内表面，电位器的控制柄伸入穹顶结构，缓冲结构设置在穹顶结构之内。遮蔽罩用于封闭遥控器的壳体与摇杆之间的缝隙，防止外部干扰物进入遥控器的内部，同时也使得遥控器更美观。
其中，缓冲结构的上半部分与摇杆的连接端连接，缓冲结构的下半部分与电位器的控制柄连接，在摇杆的连接端与电位器的控制柄之间设置有用于使摇杆的连接端相对于电位器的控制柄周向固定的固定结构。
其中，摇杆的控制端的外圆周表面包裹有摇杆外圈。该摇杆外圈用于增加使用者的操作手感。
进一步的，摇杆的控制端的外圆周表面设置有凹槽，摇杆外圈的内圆周表面设置有凸起，凸起嵌入凹槽使摇杆外圈相对于摇杆轴向固定。该凸起与凹槽用于防止摇杆外圈在使用一段时间后往上或者往下滑离原位。
更进一步的，所述缓冲结构和所述摇杆和/或所述电位器一体成型， 所述缓冲结构由柔性材料制成。该柔性材料也可部分吸收冲击力。
进一步地，所述缓冲结构的材料为TPU(Thermoplastic Urethane，热塑性聚氨酯弹性体)、TPE(Thermoplastic Elastomer，热塑性弹性体)、硅胶及硅橡胶中的任意一种；或者，所述缓冲结构的硬度为大于或等于邵氏硬度的20度且小于或等于邵氏硬度的90度。采用上述材料，可以实现较好的缓冲效果。
(三)有益效果
与现有技术相比，本发明具有以下有益效果：本发明的遥控器，其在摇杆的连接端与电位器的控制柄之间设置缓冲结构，相对于现有技术的遥控器中摇杆的连接端与电位器的控制柄为硬性连接，本发明中增设的缓冲结构能够大部分吸收从摇杆向电位器的控制柄传递的冲击力，使得即使在遥控器落地且摇杆首先着地的情况下，遥控器内的电位器、电路板和电路板上电子元件也不容易受损。

具体实施方式
以下将参考附图详细说明本发明的示例性实施方式、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施方式的各种方面，但是除非特别指出，不必按比例绘制附图。
本发明中所使用的方向性指示(如上、下、顶、底等)是为用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应随之改变。
由于本发明所作出的主要改进集中在遥控器的摇杆和电位器的结构及摇杆与电位器之间的连接关系上，因此以下的实施方式及附图中所公开的内容主要集中在遥控器的摇杆和电位器上，遥控器的其他结构不做限制，可以与现有技术相同，因此不再在本发明中进行描述。另外，在图2所示的剖视图中，仅在摇杆、电位器的控制柄和减震硅胶上增加了剖面线，这样的处理是为了更清楚地表示重要部件的结构及这些重要部件之间的连接关系。
实施方式1
如图1所示，本发明提供的一种遥控器100，所述遥控器100包括遥控器本体10及摇杆1。请一并参阅图2和图3，所述遥控器100还包括设置在遥控器本体10内的电位器3。摇杆1包括供使用者接触的控制端11和与控制端11相对的连接端12，摇杆1的控制端11突出于遥控器的壳体，电位器3包括电位器本体32和从电位器本体32突出设置的控制柄31，摇杆1的连接端12与电位器3的控制柄31连接，使得手控摇动摇杆1的控制端11时能同时带动电位器3的控制柄31，即控制柄31能够与摇杆1保持同步动作。
本发明在摇杆1的连接端12与电位器3的控制柄31之间设置有用于吸收从摇杆1向电位器3的控制柄31传递的冲击力的缓冲结构4。相对于现有技术的遥控器中摇杆的连接端与电位器的控制柄为刚性连接， 例如一体成型或借助于刚性的连接件或连接结构连接，本发明中增设的缓冲结构能够大部分吸收从摇杆1向电位器3的控制柄31传递的冲击力，使得即使在遥控器落地且摇杆1首先着地的情况下，遥控器内的电位器、电路板和电路板上电子元件也不容易受损。
所述缓冲结构4可以为减震垫、减震块、减震球、减震支架、弹簧等柔性件。以硅胶减震垫为例进行说明。所述缓冲结构4的材料可以为TPU(Thermoplastic Urethane，热塑性聚氨酯弹性体)、TPE(Thermoplastic Elastomer，热塑性弹性体)、硅胶及硅橡胶中的任意一种；或者，所述缓冲结构4的硬度为大于或等于邵氏硬度的20度且小于或等于邵氏硬度的90度。可以理解，所述缓冲结构4的材料也可以是以上各种材料的任意组合。
本实施方式中，缓冲结构4可选地采用减震硅胶垫，当然，也可采用如减震垫、减震块、减震球、减震支架、海绵垫片、弹簧或多个弹簧组合等带有弹性和/或能够吸收冲击力的物质或结构，在本实施方式中将采用减震硅胶进行描述，但其他替换也均落入本发明的保护范围之内。
在本实施方式中，如图3和图4所示，摇杆1的连接端12的端面设置有容置腔13，容置腔13从摇杆1的连接端12的端面朝摇杆1的控制端11的方向内凹，电位器3的控制柄31伸入容置腔13使电位器3的控制柄31至少在周面上受限于摇杆1，缓冲结构4设置在容置腔13之内。这种把电位器3的控制柄31插入容置腔13的连接方式能够简化连接结构，在制造时可以把容置腔13的横截面的形状和大小制成与控制柄31的横截面的形状和大小一致，以增强摇杆1的连接端12与电位器3的控制柄31之间的连接的稳定性，摇杆1与控制柄31的连接之间只能发生沿摇杆1的轴向方向的相对运动，而不会发生沿控制柄31的径向方向的相对运动，摇杆1的摇动会准确地传递给电位器3的控制柄31，不会因为缓冲结构4的存在使得控制不准确，同时这样也不易发生松动。控制柄31伸入容置腔13后便与部分的容置腔13形成一个容置空间，缓冲结构4就被限制在该容置空间内，无需外加固定结构对缓冲结构4进行固定。上述结构使得摇杆1与电位器3便于组装，易于生产， 制造成本低。
在本实施方式中，如图3所示，摇杆1的连接端12与电位器3的控制柄31可拆卸地连接，缓冲结构4可移除地设置在摇杆1的连接端12与电位器3的控制柄31之间。摇杆1的连接端12与电位器3的控制柄31之间采用可分离的结构，使得后期维修及更换缓冲结构4时更方便，降低维修及更换成本。
在本实施方式中，如图3所示，缓冲结构4为柱状结构，该柱状结构的缓冲结构4包括相对的上表面和下表面，缓冲结构4放置在容置空间后，其上表面抵顶容置腔13的顶壁，其下表面抵顶控制柄31的顶端，上表面和下表面限定出一厚度，该具有一定厚度的减震材料用于吸收冲击力。在该种结构中，柱状结构的缓冲结构4能够吸收从摇杆1的轴向方向往控制柄31的轴向方向传递的冲击力。
可以理解，所述缓冲结构4至少与所述摇杆1的连接端12及电位器3的控制柄13中的一个为一体成型，即缓冲结构4与摇杆2的连接端12一体成型或缓冲结构4与电位器3的控制柄13一体成型或缓冲结构4与摇杆1的连接端12及电位器3的控制柄13一体成型，从而省去一体成型的元件之间的连接结构或连接辅助元件。一体成型可通过注射成型或注塑成型等方式完成。
在本实施方式中，如图2和图3所示，摇杆1的控制端11的外圆周表面包裹有摇杆外圈14，用于增加使用者操作摇杆1时的舒适感和增加摩擦力。摇杆1的控制端11的外圆周表面设置有凹槽，摇杆外圈14的内圆周表面设置有凸起，凸起嵌入凹槽使摇杆外圈14相对于摇杆1的轴向固定，防止摇杆外圈14在使用一段时间后往上或者往下滑离原位。摇杆外圈14也可以局部或全部采用缓冲材料如减震硅胶制成，从而使得摇杆外圈14也可部分吸收冲击力。
在本实施方式中，如图2、图3和图4所示，摇杆1外壁成形有遮蔽罩2，遮蔽罩2具有朝向连接端12开放的穹顶结构，穹顶结构的开口边缘超过连接端12的末端或至少与之平齐，穹顶结构包括与电位器的控制柄31配合的内表面，电位器的控制柄31伸入穹顶结构而使电位器 的控制柄31至少在周面上受限于摇杆1的穹顶结构的内表面，缓冲结构4设置在穹顶结构之内、摇杆1的连接端12与控制柄31之间。遮蔽罩2用于封闭遥控器的壳体与摇杆1之间的缝隙，防止外部干扰物进入遥控器的内部，同时也使得遥控器更美观。
实施方式2
在本实施方式中，除了摇杆1与遮蔽罩2的连接方式不同于实施方式1，其他同实施方式1。如图5所示，摇杆1的连接端12与遮蔽罩2可拆卸连接，遮蔽罩2跟随摇杆1运动。遮蔽罩2与摇杆1采用可分离的结构，使得遮蔽罩2和摇杆1可分开进行生产，简化模具，便于注塑。
实施方式3
在本实施方式中，除了缓冲结构4的形状结构不同于实施方式1，其他同实施方式1。如图6所示，缓冲结构4为帽状结构，该帽状结构的缓冲结构4包裹控制柄31的顶端，该帽状结构的缓冲结构4的顶端和四周均抵顶容置腔13的壁面，该帽状结构的缓冲结构4的顶端和四周具有相同或不同的厚度，该有具一定厚度的减震材料用于吸收冲击力。在实际中，遥控器落地且摇杆1首先着地时，摇杆1可能会向电位器3的控制柄31传递多个方向的冲击力，因此在本实施方式中采用帽状结构的缓冲结构4，帽状结构的缓冲结构4能吸收多个方向的冲击力，更周全地保护电位器3、电路板和电路板上电子元件免受冲击力的损坏。
在本实施方式中，如图6所示的帽状结构也可以由多个弹簧元件组合而成，例如设置在控制柄31和连接端12之间的片簧或螺旋弹簧和均匀分布设置在控制柄31周围和容置腔侧壁之间的片簧或螺旋弹簧的组合。
实施方式4
在本实施方式中，除了摇杆1的连接端12与电位器3的控制柄31之间的连接结构不同于实施方式1，其他同实施方式1。如图7所示，可在缓冲结构4的上下两端均设置用于与摇杆1的连接端12和电位器3 的控制柄31连接的连接结构，该连接结构包括用于使摇杆1的连接端12相对于电位器3的控制柄31周向固定的套筒5，还包括至少位于连接端12和控制柄31之间的缓冲结构4。缓冲结构4的上半部分与摇杆1的连接端12连接，该缓冲结构4的下半部分与电位器3的控制柄31连接。图7中，缓冲结构4包括向上包围连接端12的上半部分、向下包围控制柄31的下半部分。可选地，缓冲结构4也可以仅包括将连接端12和控制柄31间隔开的片状结构。套筒5是为了使摇杆1与控制柄31的连接之间只能发生沿摇杆1的轴向方向的运动，而不会发生沿控制柄31的径向方向的运动而设置。该套筒5的上端的横截面的形状和大小与摇杆1的连接端12的横截面的形状和大小一致，该套筒5的下端的横截面的形状和大小与电位器3的控制柄31的横截面的形状和大小一致，缓冲结构4放置在套筒5内。同理，本领域的技术人员还可以改变减震硅胶或连接端或控制柄的结构使上述三者相连接，但只要是在摇杆的连接端与电位器的控制柄之间设置有用于吸收从摇杆向电位器传递的冲击力的缓冲结构即可，类似的替换也落入本发明的保护范围之内。
在不冲突的情况下，上述的实施方式及实施方式中的特征可以相互组合。
最后应说明的是：以上所述的各实施方式仅用于说明本发明的技术方案，而非对其限制；尽管参照前述实施方式对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述实施方式所记载的技术方案进行修改，或者对其中部分或全部技术特征进行等同替换；而这些修改或替换，并不使相应技术方案的本质脱离本发明各实施方式技术方案的范围。
