Description

一种电动平衡车 【技术领域】
本发明涉及一种代步工具，特别是涉及一种电动平衡车。
【背景技术】
随着科技的进步和发展，代步工具的类似也越发多样，近年来，市场上出现了电动平衡车这一小型代步工具；
现有的电动平衡车一般都具有一个操作杆，使用者站在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，这样的控制也称为“手控”。目前平衡车一般是一块板状的平板，其在使用过程中始终是保持水平状态，无法相对转动，所以使用者无法仅仅通过利用脚部即可对平衡车进行操作。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
【发明内容】
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供能够“脚控”的电动平衡车。
为实现上述目的，本发明提供了一种电动平衡车，包括：支撑轴，可绕所述支撑轴转动的左车轮和右车轮；所述支撑轴包括左轴和右轴，所述左轴和右轴通过连接机构可转动的配合连接；
所述电动平衡车还包括左踏板和右踏板，所述左踏板和右踏板分别固定在所述左轴和右轴上；
轮毂电机，用于驱动两个左车轮和右车轮转动；
平衡控制系统，连接于所述轮毂电机，并用于控制所述轮毂电机驱动所述 左车轮和右车轮转动。
本发明的有益效果是：本发明由于设置了左轴和右轴，以及左踏板和右踏板，这使得左踏板和右踏板可以相对转动，配合平衡控制系统等其他部件，让使用者可以通过脚部运动，而控制左踏板或右踏板中的一个或两个进行一定角度的扭转，如此便可以让使用者仅仅通过脚部活动即可对平衡车进行加减速和转向等操作，给使用者提供一种有别于“脚控”的驱动控制方式；而且，由于减少了操作杆等结构，使得平衡车的重量有所减少，更方便用户的使用，比如：上下车时可以较为轻松的抓拿；由于转动杆贯穿踏板而过，在使用者踩在踏板时，下方的转动杆起到了相当的支撑作用，如此，可以避免现有结构中，由于转轴是设置在固定板的两侧边，在踏板受到按压时，踏板下陷，而转轴与踏板配合处变形较大，而容易损坏的问题发生；而由于在左轴和右轴的配合部，有连接机构的存在，保证配合部能够具备足够的力学强度，避免配合部损坏的情况发生，从而更有力的支撑使用者的重量。
参照后文的说明和附图，详细公开了本申请的特定实施方式，指明了本申请的原理可以被采用的方式。应该理解，本申请的实施方式在范围上并不因而受到限制。在所附权利要求的精神和条款的范围内，本申请的实施方式包括许多改变、修改和等同。
针对一种实施方式描述和/或示出的特征可以以相同或类似的方式在一个或更多个其它实施方式中使用，与其它实施方式中的特征相组合，或替代其它实施方式中的特征。
应该强调，术语“包括/包含”在本文使用时指特征、整件、步骤或组件的存在，但并不排除一个或更多个其它特征、整件、步骤或组件的存在或附加。
【附图说明】
所包括的附图用来提供对本申请实施例的进一步的理解，其构成了说明书的一部分，用于例示本申请的实施方式，并与文字描述一起来阐释本申请的原 理。显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。在附图中：

图2是本发明一种电动平衡车的整体示意图；
图3是本发明一种电动平衡车中间箱体的部分爆炸图。
【具体实施方式】
为了使本技术领域的人员更好地理解本申请中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都应当属于本申请保护的范围。

本发明的有益效果是：本发明由于设置了左轴和右轴，以及左踏板和右踏板，这使得左踏板和右踏板可以相对转动，配合平衡控制系统等其他部件，让使用者可以通过脚部运动，而控制左踏板或右踏板中的一个或两个进行一定角度的扭转，如此便可以让使用者仅仅通过脚部活动即可对平衡车进行加减速和转向等操作，给使用者提供一种有别于“脚控”的驱动控制方式；而且，由于减少了操作杆等结构，使得平衡车的重量有所减少，更方便用户的使用，比如：上下车时可以较为轻松的抓拿；由于转动杆贯穿踏板而过，在使用者踩在踏板时，下方的转动杆起到了相当的支撑作用，如此，可以避免现有结构中，由于转轴是设置在固定板的两侧边，在踏板受到按压时，踏板下陷，而转轴与踏板配合处变形较大，而容易损坏的问题发生；而由于在左轴和右轴的配合部，有连接机构的存在，保证配合部能够具备足够的力学强度，避免配合部损坏的情况发生，从而更有力的支撑使用者的重量。
而若是连接机构处再加上加强筋，则进一步提高了支撑强度。
本实施例优选的，左踏板1包括第一压块11，右踏板3包括第二压块31；
左踏板1通过第一压块11固定连接于左轴8；右踏板3通过第二压块31固定连接于右轴9。左踏板和右踏板分别通过第一压块和第二压块稳固的安装在左轴和右轴上。

本实施例优选的，第一压块11的上表面设置有四个固定柱(图中未示出)，左踏板1通过固定柱固定在第一压块11的上表面；
第二压块的上表面设置有四个固定柱(图中未示出)，右踏板通过固定柱固定在第二压块的上表面；
电动平衡车还包括第一顶盖(图中未示出)、第一底盖(图中未示出)、第二顶盖(图中未示出)和第二底盖(图中未示出)，左踏板1配合设置在第一顶盖和第一底盖之间；右踏板3配合设置在第二顶盖和第二底盖之间。固定柱可以保证踏板牢固的固定在压块上，从而保证踏板不会与左轴或右轴相对转动，进而保证左踏板和右踏板进行更精密的相互转动；顶盖和底盖可以保证其内的部件不至于裸露在外，而发生不避免的损伤。
本实施例优选的，连接机构7还包括限位件(图中未示出)，用于限制左轴和右轴之间的转动角度。限位件的设置，可以避免左轴和右轴过度转动，不仅可以避免左轴和右轴扭转过度而损坏，还能够保证平衡车的踏板在进行扭转控制时，不至于失控。
本实施例优选的，电动平衡车还包括设置在左踏板1和右踏板3之间，固定连接于支撑轴的中间箱体2；中间箱体2的下部设置有避让缺口(图中未示出)；

本实施例优选的，动力结构22包括电机组25，电机组25通过固定件26固定于中间箱体2的内部上表面；
电机组25通过转轴连接于传动齿轮23，支撑脚21包括一长方形主体24，长方形主体24与传动齿轮23配合的侧面设置有传动涡轮201，传动齿轮23转动时，通过传动涡轮201控制支撑脚21向上或者向下运动；
长方形主体24的外侧均设置有加强筋202，加强筋202上设置有螺丝口(图中未示出)，固定板203通过螺丝口分别固定于加强筋202。当平衡车需要停放时，电机组通过转轴控制传动齿轮转动，继而带动传动涡轮向下运动，长方形主体即向下运动至预设位置，无需手动拉出支撑脚，给用户以操作便利；固定板和加强筋可以提高支撑脚的强度。
本实施例优选的，支撑脚21有两组，每组两个，均匀设置在中间箱体2靠近前后两侧边的位置。两组支撑脚配合轮子，保证整个平衡车停放的稳定性，避免两支撑点或三支撑点固定时，平衡车有一面不够稳固，容易前或者后侧翻 的问题发生。
本实施例优选的，中加箱体2内还设置有用于给轮毂电机、平衡控制系统和支撑脚供电的电源组；中间箱体2的左右两侧面设置有用于与左踏板及右踏板配合固定的配合件29；配合件29的中心有通孔(图中未示出)；
电源组延伸出的电源线通过该通孔连接于轮毂电机和平衡控制系统两侧的左车轮和右车轮。电源组一物多用。
