优选的，所述伸缩件包括伸缩杆、驱动杆和连接杆，所述伸缩杆为两个，所述连接杆也为两个，两个所述伸缩杆的一端和两个所述连接杆的一端固定连接，所述伸缩杆可在所述连接杆内伸缩运动，两个所述连接杆的另一端置于所述伸缩腔内，两个所述连接杆可在所述伸缩腔内伸缩运动，两个所述伸缩杆的另一端固定连接到所述驱动杆上。这是本发明设置伸缩件的一种具体方式，两个伸缩杆连接到驱动杆上，其中一个伸缩杆插入到其中一个连接杆内，其中另一个伸缩杆插入到另一个连接杆内，两个伸缩杆都可以在连接杆内伸缩运动，且两个连接杆都可以在伸缩腔内进行伸缩运动，这样不仅可以伸缩运动连接杆，还可以伸缩运动伸缩杆，可以增加伸缩件的长度，方便承载折叠板或方便直接放置物品。而且两个伸缩杆和两个连接杆承载折叠板的效果更好或者更加方便放置物品。在具体伸缩运动时，使用者可以用手控制驱动杆来控制伸缩杆和连接杆的伸缩运动。当然，本发明还可以再在连接杆和伸缩杆之间设置其他可伸缩运动的杆。
优选的，所述伸缩杆上设置有第一固定孔，所述连接杆上设置有第二固定孔，所述车体上设置有第三固定孔，当所述伸缩杆收缩到所述连接杆内，且所述连接杆收缩到所述伸缩腔内时，所述电动平衡车还包括有用于分别插入到所述第一固定孔、第二固定孔及第三固定孔内的伸缩销，将所述伸缩杆和连接杆定位于所述伸缩腔内。将第一固定孔、第二固定孔及第三固定孔三者相对应时，通过伸缩销分别插入到第一固定孔、第二固定孔及第三固定孔三者内，从而将伸缩杆和连接杆定位在伸缩腔内，防止伸缩杆和连接杆运动，这样就方便用户使用电动平衡车代步。而当使用者需要电动平衡车拉货时，可以将伸缩销取下，使用者拉动驱动杆就可以将伸缩杆及连接杆从伸缩腔内拉出，这样就方便使用者在伸缩杆及连接杆上放置折叠板或物品。或者，使用者可以仅将伸缩杆拉出，而将连接杆定位在伸缩腔内，这样也方便用户放置折叠板或物品。使用者可以根据折叠板大小或物品大小、多少来控制伸缩杆和连接杆。
优选的，所述电动平衡车还包括设置在所述车体上的把手，当所述折叠板 转动至所述把手位置时，所述折叠板固定于所述把手上。设置把手，当用户使用电动平衡车代步时，方便用户用手抓住把手，这样增加用户使用电动平衡车的稳定性，当将折叠板转动至伸缩件上时，这样就可以在折叠板放置物品，以便用户使用电动平衡车运输货物，尤其是当使用者使用电动平衡车在商场购物时，可以将所购物品直接置于转动板上，而无需额外使用篮子或背包等来盛放物品。而当用户仅需使用电动平衡车代步时，就可以将折叠板转动至把手的位置，并将折叠板安装固定在把手上，将折叠板收容到把手上，这样就大大减小了电动平衡车的整体面积，进而用户就方便使用电动平衡车代步。

优选的，所述伸缩件上设置有支撑轮，当所述电动平衡车运动时可带动所述支撑轮转动。当伸缩件上未设置支撑轮时，拉伸伸缩件，伸缩件部分位于车体外，还有一部分位于车体的伸缩腔内，在伸缩件上放置物品时，伸缩件将承载力作用到车体的伸缩腔位置，从而给伸缩腔的周围结构造成较大的作用力，这样就容易损坏伸缩腔。而本发明在伸缩件上设置支撑轮，当电动平衡车运动时带动支撑轮转动，从而支撑轮起到支撑伸缩件的作用，大大分担了伸缩腔位置的承载力，就防止伸缩腔受力过大而损坏。而且支撑轮还能够转动，可以当做辅助轮使用，从而增加电动平衡车的稳定性。
优选的，所述支撑轮包括万向轮。
优选的，当所述伸缩件收缩到所述伸缩腔内时，所述支撑轮可收缩到所述车体上。当使用者无需运输或携带物品时，可以将伸缩件收缩到车体的伸缩腔 内，这样支撑轮仍然位于车体外部，且能够随着电动平衡车的运动而转动，由于支撑轮的作用，增加了电动平衡车的摩擦力和阻力。而本发明可以将支撑轮收缩到车体上，这样支撑轮就不会跟随着电动平衡车的运动而转动，方便使用者使用电动平衡车代步。
优选的，所述支撑轮通过支撑杆和伸缩件固定连接，所述支撑杆和伸缩件通过支撑销固定连接，所述支撑杆可沿所述支撑销转动，所述车体底部设置有卡槽，所述支撑轮上设置有用于放置到所述卡槽内的卡柱，当卡柱放置到所述卡槽内时，所述支撑轮被收缩到所述车体底部；

与现有技术相比，本发明的技术效果是：本发明电动平衡车上的伸缩装置可以在车体上实现伸缩，当伸缩件从伸缩腔内伸出时，伸缩件部分位于车体外，且当折叠板转动时可以将折叠板放置到伸缩件上，这样就可以在折叠板上放置物品，尤其是当使用者使用电动平衡车在商场购物时，可以将所购物品直接置于折叠板上，而无需额外使用篮子或背包等来盛放物品。伸缩件和折叠板共同承载位于折叠板上的物品，承载效果好。
而当伸缩件位于车体外，且折叠板转动至其他位置时，这样就方便在伸缩件上放置物品，尤其是当使用者使用电动平衡车在商场购物时，可以将所购物品直接置于伸缩件上，而无需额外使用篮子或背包等来盛放物品。
另外，本发明的电动平衡车，当伸缩件从伸缩腔内伸出时，还可以将伸缩件连接到运输装置上，比如运输车，这样就更加方便在运输车上放置物品，大 大的方便使用者运输货物。或者，可以将折叠板连接到运输装置上，再或者将折叠板和伸缩件一起连接到运输装置。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。

下面结合附图和较佳的实施例对本发明作进一步详细说明。
下面参考图1至图3描述本发明实施例的电动平衡车。
如图1至图3所示，本实施例的电动平衡车100包括车体110和设置在所述车体110上的车轮120，所述电动平衡车还包括：
伸缩装置200，所述伸缩装置包括设置在所述车体上的伸缩腔111和可在所述伸缩腔111内伸缩运动的伸缩件210，当所述伸缩件从所述伸缩腔内向外伸出时，所述伸缩件部分位于所述车体外；
折叠板400，所述折叠板和车体通过销轴410固定连接，所述折叠板可通过所述销轴转动，当所述折叠板转动时，且当所述伸缩件位于所述车体外时，所述折叠板可放置于所述伸缩件上。
本实施例电动平衡车上的伸缩装置可以在车体上实现伸缩，当伸缩件从伸缩腔内伸出时，伸缩件部分位于车体外，且当折叠板转动时可以将折叠板放置到伸缩件上，这样就可以在折叠板上放置物品，尤其是当使用者使用电动平衡车在商场购物时，可以将所购物品直接置于折叠板上，而无需额外使用篮子或背包等来盛放物品。伸缩件和折叠板共同承载位于折叠板上的物品，承载效果好。
而当伸缩件位于车体外，且折叠板转动至其他位置时，这样就方便在伸缩件上放置物品，尤其是当使用者使用电动平衡车在商场购物时，可以将所购物品直接置于伸缩件上，而无需额外使用篮子或背包等来盛放物品。
另外，本实施例的电动平衡车，当伸缩件从伸缩腔内伸出时，还可以将伸 缩件连接到运输装置上，比如运输车，这样就更加方便在运输车上放置物品，大大的方便使用者运输货物。或者，可以将折叠板连接到运输装置上，再或者将折叠板和伸缩件一起连接到运输装置。
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。
作为本发明实施例的优选选择，所述伸缩件210包括伸缩杆211、驱动杆212和连接杆213，所述伸缩杆为两个，所述连接杆也为两个，两个所述伸缩杆的一端和两个所述连接杆的一端固定连接，所述伸缩杆可在所述连接杆内伸缩运动，两个所述连接杆的另一端置于所述伸缩腔内，两个所述连接杆可在所述伸缩腔内伸缩运动，两个所述伸缩杆的另一端固定连接到所述驱动杆上。这是实施例设置伸缩件的一种具体方式，两个伸缩杆连接到驱动杆上，其中一个伸缩杆插入到其中一个连接杆内，其中另一个伸缩杆插入到另一个连接杆内，两个伸缩杆都可以在连接杆内伸缩运动，且两个连接杆都可以在伸缩腔内进行伸缩运动，这样不仅可以伸缩运动连接杆，还可以伸缩运动伸缩杆，可以增加伸缩件的长度，方便承载折叠板或方便直接放置物品。而且两个伸缩杆和两个连接杆承载折叠板的效果更好或者更加方便放置物品。在具体伸缩运动时，使用者可以用手控制驱动杆来控制伸缩杆和连接杆的伸缩运动。当然，本发明还可以再在连接杆和伸缩杆之间设置其他可伸缩运动的杆。
具体的，所述伸缩杆上设置有第一固定孔，所述连接杆上设置有第二固定孔，所述车体上设置有第三固定孔，当所述伸缩杆收缩到所述连接杆内，且所述连接杆收缩到所述伸缩腔内时，所述电动平衡车还包括有用于分别插入到所述第一固定孔、第二固定孔及第三固定孔内的伸缩销220，将所述伸缩杆和连接杆定位于所述伸缩腔内。将第一固定孔、第二固定孔及第三固定孔三者相对应时，通过伸缩销分别插入到第一固定孔、第二固定孔及第三固定孔三者内，从而将伸缩杆和连接杆定位在伸缩腔内，防止伸缩杆和连接杆运动，这样就方便用户使用电动平衡车代步。而当使用者需要电动平衡车拉货时，可以将伸缩销 取下，使用者拉动驱动杆就可以将伸缩杆及连接杆从伸缩腔内拉出，这样就方便使用者在伸缩杆及连接杆上放置折叠板或物品。或者，使用者可以仅将伸缩杆拉出，而将连接杆定位在伸缩腔内，这样也方便用户放置折叠板或物品。使用者可以根据折叠板大小或物品大小、多少来控制伸缩杆和连接杆。在将伸缩杆和连接杆从伸缩腔内拉出时，伸缩杆和连接杆之间也通过伸缩销固定连接。
在本实施例中，所述车轮120为两个，分别固定在所述车体110的两侧，所述伸缩件210为一个，一个所述伸缩件可朝向所述车体的一端伸缩运动。这是设置伸缩件的一种方式，这样方便通过伸缩件放置物品，或者通过伸缩件连接运输车来运输货物。对应的，折叠板400也为一个。
以上为本实施例设置伸缩件的一种具体的方式，当然伸缩件还可以设置成其他结构，例如：
例如1：所述伸缩件包括伸缩杆和驱动杆，所述伸缩杆为两个，两个所述伸缩杆的一端置于所述伸缩腔内，两个所述伸缩杆可在所述伸缩腔内伸缩运动，两个所述伸缩杆的另一端固定连接到所述驱动杆上。这是本实施例设置伸缩件的另一种具体方式，这样设置伸缩杆强度大，方便通过驱动杆进行拉伸和收缩；而且两个伸缩杆配合驱动杆方便放置折叠板或物品，防止物品从伸缩杆及驱动杆上掉落。
例如2：所述伸缩件包括至少一个伸缩杆，所述伸缩杆的一端置于所述伸缩腔内，所述伸缩杆可在所述伸缩腔内伸缩运动。这是设置伸缩件的又一种具体方式，当设置一个伸缩杆时，就方便将伸缩杆连接到运输车上，以便通过电动平衡车驱动运输车来运输货物。当设置两个或多个伸缩杆时就方便直接在伸缩杆上放置物品或方便放置折叠板，两个或多个伸缩杆相互间隔开，对折叠板的支撑效果好，或防止物品掉落。当然，通过两个或多个伸缩杆连接运输车也是可以的。
例如3：所述车轮为两个，分别固定在所述车体的两侧，所述伸缩件为两个，两个所述伸缩件可分别朝向所述车体的两端伸缩运动。这是设置伸缩件的另一 种方式，两个伸缩件可以在车体的两端进行伸缩运动，当需要放置折叠板或物品时，一个伸缩件从车体的一端伸出，另一个伸缩件从车体的另一端伸出，这样就可以在两个伸缩件上放置物品，大大增加了放置空间，更加方便使用者携带物品。当然，此方式中可以设置一个折叠板，也可以设置两个折叠板。
以上仅是对伸缩件的几种结构的举例说明，需要说明的是，本实施例对伸缩件的结构并不限于此。
在本实施例中，所述电动平衡车100还包括设置在所述车体110上的把手500，当所述折叠板400转动至所述把手500位置时，所述折叠板400固定于所述把手500上。设置把手，当用户使用电动平衡车代步时，方便用户用手抓住把手，这样增加用户使用电动平衡车的稳定性，当将折叠板转动至伸缩件上时，这样就可以在折叠板放置物品，以便用户使用电动平衡车运输货物，尤其是当使用者使用电动平衡车在商场购物时，可以将所购物品直接置于转动板上，而无需额外使用篮子或背包等来盛放物品。而当用户仅需使用电动平衡车代步时，就可以将折叠板转动至把手的位置，并将折叠板安装固定在把手上，将折叠板收容到把手上，这样就大大减小了电动平衡车的整体面积，进而用户就方便使用电动平衡车代步。
具体的，所述把手和折叠板通过螺丝固定连接。螺丝固定方便安装和拆卸，且螺丝固定牢固、容易实现。
在本实施例中，所述折叠板400通过所述销轴410可拆卸的固定在所述车体110上。折叠板通过销轴可拆卸的固定在车体上，从而就方便将折叠板从车体上拆卸下来，这样当无需运输或携带物品时，用户就可以将折叠板拆卸下来，以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，就可以将折叠板安装固定在车体上。
作为本实施例更优选的选择，如图4所示，本实施例的电动平衡车100还包括支撑轮300，所述支撑轮300设置在伸缩件210上，具体是设置在驱动杆212的中部位置。当伸缩件上未设置支撑轮时，拉伸伸缩件，伸缩件部分位于车 体外，还有一部分位于车体的伸缩腔内，在伸缩件上放置物品时，或伸缩件承载折叠板时，伸缩件将承载力作用到车体的伸缩腔位置，从而给伸缩腔的周围结构造成较大的作用力，这样就容易损坏伸缩腔。而本实施例在伸缩件上设置支撑轮，当电动平衡车运动时带动支撑轮转动，从而支撑轮起到支撑伸缩件的作用，大大分担了伸缩腔位置的承载力，就防止伸缩腔受力过大而损坏。而且支撑轮还能够转动，可以当做辅助轮使用，从而增加电动平衡车的稳定性。
其中，本实施例的支撑轮为万向轮。
其中，本实施例的支撑轮可以固定连接在驱动杆上。
其中，本实施例的支撑轮也可以收缩到车体上，例如：
如图5和图6所示，当所述伸缩件收缩到所述伸缩腔内时，所述支撑轮可收缩到所述车体上。当使用者无需运输或携带物品时，可以将伸缩件收缩到车体的伸缩腔内，以及将折叠板转动至把手位置，并固定，这样支撑轮仍然位于车体外部，且能够随着电动平衡车的运动而转动，由于支撑轮的作用，增加了电动平衡车的摩擦力和阻力。而本实施例可以将支撑轮收缩到车体上，这样支撑轮就不会跟随着电动平衡车的运动而转动，方便使用者使用电动平衡车代步。
具体的，所述支撑轮300通过支撑杆310和伸缩件210的驱动杆212固定连接，所述支撑杆和驱动杆通过支撑销固定连接，所述支撑杆可沿所述支撑销转动，所述车体110底部设置有卡槽112，所述支撑轮300上设置有用于放置到所述卡槽112内的卡柱320，当卡柱放置到所述卡槽内时，所述支撑轮被收缩到所述车体底部。
更具体的，支撑轮上设置有轮轴，所述卡柱为轮轴的端部向外延伸的部分，卡柱为两个分别通过轮轴的两端向外延伸形成。对应的卡槽112也设置有两个，具体的，车体底部设置有片状的卡板，卡板为两个，相邻设置，卡槽设置在卡板上。
所述支撑杆两侧分别固定连接有第一连杆330，所述第一连杆一端可转动连接在所述支撑杆上，所述第一连杆另一端可转动连接有第二连杆340，所述第二 连杆可转动连接到所述伸缩件上，具体是，第二连杆340可转动的连接到连片113上，连片设置在伸缩件的驱动杆上。
在收缩支撑轮时，作用力到第一连杆和第二连杆的连接部位，从而使得第一连杆和第二连杆相互转动，从而驱动支撑杆沿支撑销转动，且将伸缩件收缩至伸缩腔内，这样就可以将支撑轮上的卡柱放置到卡槽内，从而实现将支撑轮收纳到车体底部，防止支撑轮转动，以便用户使用电动平衡车代步。
当拉伸伸缩件时，伸缩件从伸缩腔内拉出，支撑轮随着被拉出，使得第一连杆和第二连杆相互转动，且使得第一连杆和第二连杆逐渐被拉直，从而第一连杆和第二连杆的相互作用对支撑轮起到支撑、定位的作用，防止支撑轮任意随支撑销转动。
在本实施例中，该支撑轮上还设置有刹车片。
在本实施例中，所述折叠板的边沿设置有挡板。设置挡板对放置于折叠板上的物品起到限位的作用，防止位于折叠板上的物品掉落。其中，挡板可以沿折叠板的边沿设置一圈，也可以设置成其他结构，比如：设置两个相对的条形结构。
在本实施例中，所述折叠板上设置有通孔。设置通孔，以便通气或漏水，这样当下雨天或者折叠板上放置的物品有水流出，就可以通过通孔流出，而防止有水停留于折叠板上，或通过折叠板流到电动平衡车上。而且，设置通孔，使用者还可以通过通孔对放置于折叠板上的物品进行定位。
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。
