Description

一种电动平衡车 【技术领域】
本发明涉及平衡车领域，更具体的说，涉及一种电动平衡车。
【背景技术】
电动平衡车，又叫体感车、思维车，其运作原理主要是建立在一种被称为“动态稳定”的基本原理上，利用车体内部的陀螺仪和加速度传感器，来检测车体姿态的变化，并利用伺服控制系统，精确地驱动电机进行相应的调整，以保持系统的平衡。
现有的电动平衡车一般有两种，一种是车体上具有一个操作杆，使用者站在电动平衡车的脚踏平台上对操作杆进行操作，从而前进、后退及停止，这样的控制也称“手控”。另一种是车体由两部分组成，左部分和右部分之间通过转动机构实现相互转动，从而实现“脚控”。参见中国发明专利公布号为CN104029769A(公布日：20140910)的电动平衡扭扭车，其仅仅用于用户代步，功能单一。
【发明内容】
本发明所要解决的技术问题是提供一种多功能的电动平衡车。
本发明的目的是通过以下技术方案来实现的：
根据本发明的一个方面，本发明公开了一种电动平衡车，包括车体和固定在所述车体上的车轮，所述电动平衡车还包括：
放置板，所述放置板可活动的固定在所述车体上；
伸缩装置，所述伸缩装置固定在所述车体端部，当所述伸缩装置固定在所述车体上时，所述伸缩装置位于车体外部，所述放置板可放置于所述伸缩装置上；所述伸缩装置包括有至少四个横杆，所述至少四个横杆相互铰接、且可相互转动，其中所述至少四个横杆中的两个铰接到所述车体上；
支撑轮，所述支撑轮设置在所述至少四个横杆上，当所述电动平衡车运动时可带动所述支撑轮转动。
与现有技术相比，本发明的技术效果是：本发明的伸缩装置包括有至少四个横杆，所述至少四个横杆相互铰接、且可相互转动，这样各个横杆相互之间就可以在同一平面上进行转动，使得各个横杆产生的平面大小产生变化，当各个横杆处于拉伸状态时，各个横杆形成的面积大，比如形成平行四边形结构、或矩形结构等等。而且其中有两个横杆铰接到车体上，以及所述至少四个横杆上设置有支撑轮，从而，就可以在相互连接的横杆上放置物品，尤其是当各个横杆处于拉伸状态，各个横杆形成的面积较大，又位于车体外部，且有支撑轮承载重量，这样就可以在横杆上放置较多的物品，以便用户使用电动平衡车运输货物。比如：当用户在商场购物时，可以将所购物品直接置于翻转板上，或者将物品先放置到篮子内或背包内，然后再将篮子或背包放置到横杆上，横杆的个数至少为四个，这样至少四个横杆对物品、篮子或背包的支撑效果好，防止其掉落，从而就无需用户亲自拿物品。
本发明的电动平衡车不仅方便使用者代步，而且方便使用者运输物品，实现了多功能。
另外，本发明在车体上设置放置板，且放置板可在车体上活动，在放置板活动过程中可以将放置板放置到伸缩装置上，用户在使用电动平衡车运输物品时就可以将物品放置到放置板上，而无需放置篮子中、或背包中。本发明通过设置放置板用户可以在放置板上放置更加细小的物品，更加方便用户运输物品。

其中，图6至图12示出了本实施例对本发明实施例做出进一步改进的示意图，图6至图8示出了各个横杆处于收缩状态、且放置板放置在车体上的示意图，图9至图12示出了各个横杆处于拉伸状态、且放置板放置在所述横杆上的示意图。
在本实施例中，如图1至图5所示，本实施例公开一种电动平衡车100，电动平衡车100包括车体110和固定在所述车体110上的车轮120，所述电动平衡车100还包括固定在所述车体110端部的伸缩装置200和支撑轮220，当所述伸 缩装置200固定在所述车体110上时，所述伸缩装置200位于车体110外部，所述伸缩装置200包括有至少四个横杆210，所述至少四个横杆210相互铰接、且可相互转动，其中所述至少四个横杆210中的两个铰接到所述车体110上，所述支撑轮220设置在所述至少四个横杆210上，当所述电动平衡车100运动时可带动所述支撑轮220转动。
本实施例的伸缩装置包括有至少四个横杆，所述至少四个横杆相互铰接、且可相互转动，这样各个横杆相互之间就可以在同一平面上进行转动，使得各个横杆产生的平面大小产生变化，当各个横杆处于拉伸状态时，各个横杆形成的面积大，比如形成平行四边形结构、或矩形结构等等。而且其中有两个横杆铰接到车体上，以及所述至少四个横杆上设置有支撑轮，从而，就可以在相互连接的横杆上放置物品，尤其是当各个横杆处于拉伸状态，各个横杆形成的面积较大，又位于车体外部，且有支撑轮承载重量，这样就可以在横杆上放置较多的物品，以便用户使用电动平衡车运输货物。
比如：当用户在商场购物时，可以将所购物品直接置于翻转板上，或者将物品先放置到篮子内或背包内，然后再将篮子或背包放置到横杆上，横杆的个数至少为四个，这样至少四个横杆对物品、篮子或背包的支撑效果好，防止其掉落，从而就无需用户亲自拿物品。
本实施例的电动平衡车不仅方便使用者代步，而且方便使用者运输物品，实现了多功能。
在本实施例中，各个横杆在铰接在同一平面上，从而使得各个横杆可以在同一平面上相互转动。
在本实施例中，作为本实施例的一种优选选择，所述横杆的个数设定为四个，四个横杆相互之间铰接，铰接容易转动，就使得四个横杆相互之间可以进行转动，这样四个横杆就可以在同一平面上随意拉伸或收缩，使得四个横杆可以形成不同的形状结构，这样就方便在四个横杆上放置不同种类的物品，极大的方便用户使用四个横杆相互转动产生的变化来运输物品。当然，本实施例也 可以设置五个横杆、六个横杆或更多个横杆，需要说明的是，对于本领域技术人员而言，本实施例对横杆个数的限定并不限于此。
具体的，所述四个横杆210包括第一横杆211、第二横杆212、第三横杆213及第四横杆214，其大小相同，四个结构、形状相同的横杆相互之间可以转动，四个横杆在转动、过程中形成拉伸或收缩动作，从而使得四个横杆形成不同形状，这样就方便放置不同的物品，用户可以根据物品的大小、结构来控制四个横杆形成的形状，以使得物品放置到横杆上更加稳定。
在本实施例中，作为本实施例的另一种优选选择，本实施例的支撑轮设定为两个，两个支撑轮同时对多个横杆进行支撑，具体是两个支撑轮支撑四个横杆，这样支撑力更好，更加方便用户在横杆上放置物品。当然，需要说明的是，本实施例对支撑杆的个数的限定并不限于此，比如：所述支撑轮的个数为一个，其中，在设置一个支撑轮时，所述第一横杆和第二横杆铰接到所述车体上，所述支撑轮固定连接到所述第三杆和第四杆的铰接位置处。这是设置一个支撑轮的一种具体方式，当然，设置一个支撑轮还可以有其他方式，比如：将一个支撑轮设置到四个横杆的其中一个上，或者将一个支撑轮设置到其他横杆的铰接处。另外，本实施例支撑杆的个数还可以设置三个、甚至设置更多个。
在本实施例中，本实施例的支撑轮220包括第一支撑轮221和第二支撑轮222。
具体的，所述第一横杆211和第二横杆212铰接到所述车体110上，所述第一支撑轮221固定连接到所述第一横杆211和第三横杆213铰接的位置处，所述第二支撑轮222固定连接到所述第二横杆212和第四横杆214铰接的位置处。这是本实施例固定连接两个支撑轮的一种优选方式。当然，本实施例也可以将两个支撑轮固定连接到其他位置处，比如：将第一支撑轮固定连接到第三横杆上，将第二支撑轮固定连接到第四横杆上。需要说明的是，本实施例对支撑轮固定连接的方式并不限于此。
进一步的，两个支撑轮220通过支撑杆230固定连接到横杆的连接位置处。
具体的，所述第一支撑轮221通过第一支撑杆231固定连接到所述第一横杆211和第三横杆213的铰接处；所述第二支撑轮222通过第二支撑杆232固定连接到所述第二横杆212和第四横杆214的铰接处，所述第一支撑杆231和第二支撑杆232通过转轴233固定连接，所述第一支撑杆231和第二支撑杆232通过所述转轴233可相互转动，当四个所述横杆伸缩时驱动所述第一支撑杆和第二支撑杆转动。或者，当第一支撑杆和第二支撑杆围绕转轴进行转动时，第一支撑杆和第二支撑杆驱动四个横杆运动，使得四个横杆进行拉伸或收缩。
更进一步的，所述第一横杆211和第三横杆213之间通过第一伸缩轴216固定连接，所述第二横杆212和第四横杆214通过第二伸缩轴217固定连接，所述第一支撑杆231固定连接到所述第一伸缩轴216上，所述第二支撑杆232固定连接所述第二伸缩轴217上。
在本实施例中，横杆210和车体110可拆卸固定连接，在不使用伸缩装置时，可以将伸缩装置及支撑轮从车体上拆卸下来，这样就方便用户使用电动平衡车代步。而当用户需要使用电动平衡车运输物品时，可以将伸缩装置安装固定在车体的端部，并拉伸伸缩装置的横杆，使得各个横杆处于拉伸状态，以便在各个横杆上放置物品。
具体的，所述第一横杆211和第二横杆212通过连接杆215固定连接，且所述车体110设置有用于放置所述连接杆215的连接孔。连接杆插入到连接孔内实现伸缩装置和车体之间的固定连接。容易安装固定和拆卸。
进一步的，连接杆上设置有销孔，对应的，伸缩装置还包括用于插入到销孔内的限位销，这样就可以将连接杆限位在连接孔内，以防止其任意晃动。
在本实施例中，所述车体110在所述连接孔两侧设置有用于放置所述伸缩装置及支撑轮的放置空间111，如图1至图4所示。
在本实施例中，所述电动平衡车还包括定位件，当所述至少四个横杆处于拉伸状态时，所述定位件定位于所述至少四个横杆的铰接处，使所述至少四个横杆保持拉伸状态。定位件起到定位作用，以防止横杆任意转动。本实施例定 位件具体是杆状结构，其两端分别具有卡点，对应的，横杆在铰接附近位置设置有用于放置卡点的凹点，当卡点放置到凹点内时定位将各个横杆定位。这样本实施例设置定位件的一种具体方式，当然，本实施例的定位件还可以设置成其他结构，需要说明的是，本实施例对定位件的限定并不限于此。
在本实施例中，所示支撑轮包括有万向轮。
作为对本实施例的进一步改进，如图6至图12所示，所述电动平衡车还包括有放置板300，所述放置板300可活动的固定在所述车体110上；当所述伸缩装置固定在所述车体上时，所述伸缩装置位于车体外部，所述放置板300可放置于所述伸缩装置上，具体是放置在横杆上。
本实施例在车体上设置放置板，且放置板可在车体上活动，在放置板活动过程中可以将放置板放置到伸缩装置上，用户在使用电动平衡车运输物品时就可以将物品放置到放置板上，而无需放置篮子中、或背包中。本实施例通过设置放置板用户可以在放置板上放置更加细小的物品，更加方便用户运输物品。
其中，所述放置板300一端通过翻转销400固定在所述车体的顶部边沿位置，且靠近所述伸缩装置，所述放置板可沿所述翻转销在所述车体进行翻转转动，当所述放置板沿其固定端在所述车体上翻转时，所述放置板的部分突出于所述车体外，并放置于所述横杆上。
在本实施例中，所述放置板300包括第一放置板310和第二放置板320，所述第一放置板和第二放置板通过连接件330可折叠固定连接，所述车体110设置有用于放置所述第一放置板和第二放置板的放置槽112；所述第一放置板上设置有定位孔，所述伸缩装置上设置有用于插入到所述定位孔340内的定位销。其中，定位销为设置第三横杆和第四横杆连接处的第三伸缩销。本实施例设置两个放置板，就可以大大增加放置板的大小，这样可以在放置板上放置更多的物品。而且由于横杆在拉伸时可以形变成平行四边形结构，其占用面积大，因此，其承载放置板的面积也大，这样就可以承载起增加面积的放置板。
这是本实施例设置放置板的一种更优选择，当然，本实施例放置板的安装 固定结构还可以设置成其他方式：
例如1：所述放置板通过一个转动销固定连接在所述车体的顶部边沿位置，且靠近所述伸缩装置，所述放置板可通过所述转动销在所述车体上转动，当所述放置板沿所述转动销在所述车体上转动时，所述放置板的部分突出于所述车体外，并放置于所述横杆上。
例如2：所述车体设置有用于收纳所述放置板的收纳腔，所述放置板可在所述收纳腔内伸缩运动，当所述放置板从所述收纳腔内向外伸出时，所述放置板部分位于所述车体外，所述电动平衡车还包括用于将所述放置板定位于所述车体上的定位机构，所述定位机构包括设置在所述车体上的定位件，所述伸缩板上设置有用于放置所述定位件的定位孔，所述车体设置有用于放置所述定位件的通孔，所述定位件包括定位圈、定位块、用于放置到所述通孔内的本体和用于放置到所述定位孔内的定位柱，所述定位柱位于所述定位件一端的端部，所述定位块位于所述定位件的另一端的端部，所述定位圈位于所述定位柱和本体之间，当所述定位柱放置到所述定位孔内时终止于所述定位圈，所述定位圈大于所述通孔大小，所述定位块大于所述通孔大小，所述本体的高度大于所述通孔的长度，当所述本体放置于所述通孔内时，所述本体可在所述通孔内沿所述通孔长度方向运动，并终止于定位块和定位圈，所述车体在所述通孔的一端设置有与所述定位块相配合的第一端面，所述车体在所述通孔的另一端设置有第二端面，所述定位机构还包括有弹性件，当所述本体放置在所述通孔内时，所述弹性件设置在所述定位圈和第二端面之间，所述弹性件包括有用于套接到所述本体上的弹簧，所述通孔设置在所述伸缩腔的开口位置，所述伸缩板上设置有滑槽，所述定位孔设置在所述滑槽内，当所述伸缩板在所述伸缩腔内进行伸缩运动时，所述滑槽沿所述定位柱运动；所述伸缩板设置有与所述伸缩腔配合的限位板，所述限位板位于所述滑槽内侧。
需要说明的是，以上几种放置板的具体结构及其固定方式，仅仅是本实施例对放置板的举例说明，而对于本领域技术人员而言，本实施例对放置板的限 定并不限于。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
