Description

电动车
本申请要求了申请日为2019年10月24日，申请号为201911017140.9的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电动车领域，特别涉及一种采用电动工具电池包的电动车。
背景技术
电动车作为一种绿色环保的交通工具，越来越被广泛使用。现有技术中，两轮的电动自行车都需要使用到电池。一般而言，大多数情况下电池都采用固定式安装的方式安装在电池盒中，由于电池盒结构防水能力不强，为了避免容易发生短路或者腐蚀等现象，对电池造成损坏，电池盒中的电池一般都不易进行安装和拆卸。电池盒则嵌入固定设置在电动自行车的某处，例如踏板护板上、鞍座的下方等。当需要充电时，将充电器直接***到电池盒上的接口处，以对其内部的电池进行充电。上述情况中，电池盒中的电池不方便进行更换，当电池电量不足时，只能进行充电，无法通过立马快捷的更换电池的方式使得人们能够继续使用电动车。

本发明的技术方案具有以下显著有益效果：
1、本申请中电动车的电池盒的盒体通过转动的方式实现底座和盖体之间的开启和关闭，因此，当盖体转动开启后，可以方便的对盒体中的电池包进行更换。通过底座和盖体将电池包相对密封的设置在盒体的容纳腔室中，在电池包使用产生热量后，外部的气流能够通过相对的第一气流通道和第二气流通道形成散热流道与盒体内的容纳腔室的气体进行交换，从而可以有效降低盒体1中电池包的温度。其次，第一通风格栅和第二通风格栅相对应的盒体内分别设置有第一挡水件和第二挡水件，第一挡水件的两侧和下侧与第一通风格栅相连接，仅上端与第一侧面之间形成第一气流通道，第二挡水件的两侧和下侧与第二通风格栅相连接，仅上端与第二侧面之间形成第二气流通道，因此，外界的雨水等分别通过第一通风格栅和第二通风格栅后无法流入至盒体内部与电池包相接触，第一腔室和第二腔室中积攒的雨水会从第一通风格栅、第二通风格栅的下端排出，在上述结构下，又能保证外界的气流从第一腔室和第二腔室的上端流入至盒体内部。所以说，本申请中的电池盒在保证电池包方便更换以及实现电池盒内部散热的前提下有效避免了雨水进入电池盒而对电池包造成影响。
2、本申请中的电池盒在第一端面和第二端面之间设置有密封机构，使得第一端面和第二端面之间紧密密封，如此可以有效避免外部的雨水进入电池盒而对电池包造成影响。当外部的雨水突破密封机构以后进入电池盒内部后，导水机构能承接自所述密封机构处泄露至所述盒体中的水，对该部分水进行收集，避免水进一步进入电池盒而对电池包造成影响。

在保证电池包方便更换的前提下，为了能够在常规的电瓶车上方便的加装能够更换电动工具用的电池包的电池盒，在本申请中提出了一种电动车，图6为电池盒安装在电瓶车上的第一种实施方式，图7为电池盒安装在电瓶车上的第二种实施方式，图8为电池盒安装在电瓶车上的第三种实施方式，图9为电池盒安装在电瓶车上的第四种实施方式，图10为电池盒安装在电瓶车上的第五种实 施方式，图11为电池盒安装在电瓶车上的第六种实施方式，图12为电池盒安装在电瓶车上的第七种实施方式，图13为电池盒安装在电瓶车上的第八种实施方式，图14为电池盒安装在电瓶车上的第九种实施方式，如图6至图14所示，该电动车可以包括电池盒70，电池盒70具有容纳腔室的盒体1，电池盒中能够容纳至少一个电动工具用的电池包7，电池包7与盒体1之间可拆卸连接。
本申请中电瓶车能够在不影响用户正常使用的情况下，在合适的位置上加装电池盒，该种电池盒中能够安装可拆卸更换的电动工具用的电池包7，如此，可以使得电瓶车的电池包与电动工具的电池包具有通用性。当电瓶车的电池包7的电量用完时，可以随便将盒体拆开以对电池包进行更换，避免了充电等待的时间，方便用户长时间使用电瓶车。
在保证电池包方便更换以及实现电池盒内部散热的前提下，为了能够有效避免雨水进入电池盒而对电池包造成影响，在本申请中提出了一种电动车，图1为本发明实施例中带有电池盒的电动车的整体示意图，图2为本发明实施例中电池盒的结构示意图，如图1和图2所示，本申请中的电动车，包括车体和安装在车体上的电池盒。其中，电池盒可以包括：具有容纳腔室的盒体1，容纳腔室用于容纳至少一个电动工具用的电池包，电池包7与盒体1之间可拆卸连接。盒体1包括底座3和盖体2，盖体2能与底座3实现开启和关闭；盒体1具有第一侧面11和第二侧面12，第一侧面11上具有第一通风格栅13，第二侧面12上具有第二通风格栅14，盒体1内设置有第一挡水件5和第二挡水件6，第一挡水件5与第一通风格栅13的两侧和下侧相连接，第一挡水件5的上端与第一侧面11之间形成有与盒体1内部、第一通风格栅13相连通的第一气流通道，第二挡水件6与第二通风格栅14的两侧和下侧相连接，第二挡水件6的上端与第二侧面12之间形成有与盒体1内部、第二通风格栅14相连通的第二气流通道。
本申请中电动车中的电池盒的盒体1通过转动的方式实现底座3和盖体2之间的开启和关闭，因此，当盖体2转动开启后，可以方便的对盒体1中的电池包7进行更换。通过底座3和盖体2将电池包7相对密封的设置在盒体1的容纳腔室中， 在电池包7使用产生热量后，外部的气流能够通过相对的第一气流通道和第二气流通道形成散热流道与盒体1内的容纳腔室的气体进行交换，从而可以有效降低盒体1中电池包7的温度。其次，第一通风格栅13和第二通风格栅14相对应的盒体1内分别设置有第一挡水件5和第二挡水件6，第一挡水件5的两侧和下侧与第一通风格栅13相连接，仅上端与第一侧面11之间形成第一气流通道，第二挡水件6的两侧和下侧与第二通风格栅14相连接，仅上端与第二侧面12之间形成第二气流通道，因此，外界的雨水等分别通过第一通风格栅13和第二通风格栅14后无法流入至盒体1内部与电池包7相接触，第一腔室和第二腔室中积攒的雨水会从第一通风格栅13、第二通风格栅14的下端排出，在上述结构下，又能保证外界的气流从第一腔室和第二腔室的上端流入至盒体1内部。所以说，本申请中的电池盒70在保证电池包7方便更换以及实现电池盒70内部散热的前提下有效避免了雨水进入电池盒70而对电池包7造成影响。
为了能够有效避免雨水进入电池盒而对电池包造成影响，在本申请中提出了一种电动车，图4为本发明实施例中电池盒的剖面图，图5为图4中A处的局部放大图，如图4和图5所示，包括车体和安装在车体上的电池盒。其中，电池盒可以包括：具有容纳腔室的盒体1，容纳腔室用于容纳至少一个电动工具用的电池包7，电池包7与盒体1之间可拆卸连接。盒体1包括底座3和盖体2，盖体2能与底座3实现开启和关闭；在盖体2与底座3处于关闭时，底座3具有与盖体2相贴的第一端面31，盖体2具有与底座3相贴的第二端面21，第一端面31和第二端面21处设置有密封机构；盒体1还包括设置在密封机构的内侧的导水机构，导水机构能承接自密封机构处泄露至盒体1中的水。
本申请中的电池盒在第一端面31和第二端面21之间设置有密封机构，使得第一端面31和第二端面21之间紧密密封，如此可以有效避免外部的雨水进入电池盒70而对电池包7造成影响。当外部的雨水突破密封机构以后进入电池盒70内部后，导水机构能承接自密封机构处泄露至盒体1中的水，对该部分水进行收集，避免水进一步进入电池盒70而对电池包7造成影响。
为了能够更好的了解本申请中的电动车，下面将对其做进一步解释和说明。如图1和图2所示，电动车包括车体和安装在车体上的电池盒。电池盒70可以包括具有容纳腔室的盒体1，盒体1可以大体呈长方体状、正方体状或多边体等等，其只需要与电池盒70内部的电池包7所需的体积相匹配即可。
在一种具体的实施方式中，底座3可以包括下端面、后端面、上端面、左端面、右端面和前端面，其中，上端面、左端面、右端面和前端面为不完整的盒体1端面，其需要与盖体2相配合，从而形成整个完整的盒体1。盖体2可以包括上端面、前端面、左端面和右端面，其中，盖体2的上端面与底座3的上端面相配合，盖体2的左端面与底座3的左端面相配合，盖体2的右端面与底座3的右端面相配合，盖体2的前端面与底座3的前端面相配合，从而形成盒体1的上端面、前端面、左端面和右端面。底座3可以通过转动的方式能与底座3实现开启和关闭，例如，盖体2的下端与底座3之间通过铰链连接方式连接，以使底座3和盖体2之间实现转动。在一种具体的实施方式中，底座3的前端面和盖体2的前端面之间可以插设有销，如此以实现铰链连接方式。在上述结构中，当盖体2绕铰链转动打开后，盒体1内的电池包7可以直接在上方取出或者放入。当然的，底座3可以通过卡扣方式等其它方式与底座3实现开启和关闭。
如图1和图2所示，底座3或盖体2上安装有锁机构4，通过锁机构4实现盖体2和底座3之间的锁定和解锁。例如，锁机构4可以安装在盖体2上，底座3上具有一限位钩，当底座3和盖体2关闭时，通过将钥匙***锁机构4并进行转动，从而使得锁机构4中的卡勾转动与限位钩相勾出，此时便无法打开盖体2。当然，锁机构4也可以安装在底座3上，在此并不做任何限制。
如图1和图2所示，盒体1具有第一侧面11和第二侧面12，作为优选的，第一侧面11和第二侧面12尽可能处于相对的位置上。例如，第一侧面11可以是盒体1的左端面，第二侧面12可以是盒体1的右端面；又例如，第一侧面11可以是盒体1的前端面，第二侧面12可以是盒体1的后端面。第一侧面11和第二侧面12相对时，如此，能够便于将盒体1内的气体与外界气体的交换，以有利于对电池包7 进行降温。
如图1和图2所示，第一侧面11上可以具有第一通风格栅13，该第一通风格栅13可以位于底座3上，也可以位于盖体2上。第二侧面12上可以具有第二通风格栅14，同样的，该第二通风格栅14可以位于底座3上，也可以位于盖体2上。
如图1和图2所示，盒体1内可以设置有第一挡水件5和第二挡水件6。第一挡水件5的位置与第一通风格栅13相对。第一挡水件5的两侧、下端分别与第一通风格栅13的两侧、下端相连接。第一挡水件5的上端与第一侧面11之间形成与盒体1内部、第一通风格栅13相连通的第一气流通道。具体而言，第一挡水件5的上端与盒体1之间形成有第一间隙，第一间隙分别与盒体1内部、第一通风格栅13相连通，从而形成第一气流通道，盒体1外部的气流能够通过第一气流通道流入盒体1内部，或盒体1内部的气流能够通过第一气流通道流至盒体1外部。第一挡水件5的左侧、右侧和下端与盒体1之间为密封连接，第一挡水件5只有上端与盒体1之间形成第一间隙，以使第一通风格栅13通过第一间隙与容纳腔室相连通。当然，第一挡水件5在垂直于第一通风格栅13方向的投影需要覆盖第一通风格栅13。在该结构下，雨水通过第一通风格栅13到达第一通风格栅13与第一挡水件5之间后，无法从第一挡水件5的左右侧或者下端流入至盒体1内部，进而影响电池包7的安全性，而外界的流体能通过第一挡水件5上端的第一间隙流入至盒体1内，盒体1内的气体也能够从第一间隙流出至盒体1外，如此在实现电池盒70内部散热的前提下，又能够有效避免雨水进入电池盒70而对电池包7造成影响。
在一种可行的实施方式中，当第一通风格栅13位于盖体1上时，第一挡水件5与盖体1一体成型。在另一种可行的实施方式中，当第一通风格栅13位于底座3上时，第一挡水件5与底座3一体成型。
如图1和图2所示，第二挡水件6的位置与第二通风格栅14相对。第二挡水件6的的两侧、下端分别与第二通风格栅14的两侧、下端相连接。第二挡水件6的上端与第一侧面12之间形成与盒体1内部、第二通风格栅14相连通的第二气流通 道。具体而言，第二挡水件6的上端与盒体1之间形成有第二间隙15，第二间隙15分别与盒体1内部、第二通风格栅14相连通，从而形成第二气流通道，盒体1外部的气流能够通过第二气流通道流入盒体1内部，或盒体1内部的气流能够通过第二气流通道流至盒体1外部。第二挡水件6的左侧、右侧和下端与盒体1之间为密封连接，第二挡水件6只有上端与盒体1之间形成第二间隙15，以使第二通风格栅14通过第二间隙15与容纳腔室相连通。当然，第二挡水件6在垂直于第二通风格栅14方向的投影需要覆盖第二通风格栅14。第一通风格栅13、第一间隙、容纳腔室、第二间隙15和第二通风格栅14可以形成散热流道，当风吹向第一通风格栅13或第二通风格栅14时，其中一个通风格栅作为进气口，另一个相对侧面上的通风格栅作为出气口，如此外界与盒体1内的气体形成高效的对流，有处于提高对电池包7的降温效率。
在一种可行的实施方式中，当第二通风格栅14位于盖体1上时，第二挡水件6与盖体1一体成型。在另一种可行的实施方式中，当第二通风格栅14位于底座3上时，第二挡水件6与底座3一体成型。
在上述实施方式中，第一通风格栅13上的格栅条可以朝向第一腔室的下端，第二通风格栅14上的格栅条可以朝向第二腔室的下端，如此，当雨水留在，第一通风格栅13或第二通风格栅14上时，雨水能够沿着格栅条向下滑落，从而滑落至第一通风格栅13和第一挡水件5之间或第二通风格栅14和第二挡水件6之间中，第一通风格栅13和第一挡水件5之间的底部与第一通风格栅13的下端相连通，第二通风格栅14和第二挡水件6之间的底部与第二通风格栅14的下端相连通，在第一通风格栅13和第一挡水件5之间或第二通风格栅14和第二挡水件6之间中残留的雨水会从第一通风格栅13的下端或第二通风格栅14的下端排出。
在一种可行的实施方式中，图3为本发明实施例中电池盒的透视图，图4为本发明实施例中电池盒的剖面图，图5为图4中A处的局部放大图，如图3至图5所示，在盖体2与底座3处于关闭时，底座3具有与盖体2相贴的第一端面31，例如，第一端面31可以位于底座3的上端面、左端面、左端面和前端面处。盖体2 具有与底座3相贴的第二端面21，例如，第一端面31可以位于盖体2的上端面、左端面、左端面和前端面处。第一端面31和第二端面21处设置有密封机构。密封机构包括：开设在第一端面31和第二端面21的其中一者上的凹槽32、开设在其中另一者上具有能嵌入凹槽32的凸起部、设置在凹槽32中的密封件33。
在一种可行的实施方式中，第一端面31上开设有凹槽32，凹槽32可以沿着第一端面31延伸，可以延伸至整个第一端面31，也可以仅延伸至部分第一端面31上。第二端面21上具有能嵌入凹槽32的凸起部22，凸起部22与凹槽32的长度相匹配。凹槽32中设置有密封件33。当盖体2与底座3处于关闭时，第二端面21上的凸起部22可以嵌入第一端面31的凹槽32中并压紧设置在凹槽32中的密封件33，如此可以实现底座3和盖体2之间的高效密封。在另一种可行的实施方式中，第二端面31上开设有凹槽32，第一端面21上具有能嵌入凹槽32的凸起部22。
在一种可行的实施方式中，如图3所示，底座3上可以具有排水孔34，排水孔34可以位于底座3的侧边附近，排水孔34具有向下倾斜的趋势，当然也可以是完全的竖直状态。排水孔34与凹槽32的最低处相连通。当底座3的凹槽32中有残留的水时，水会沿着凹槽32向下流动，最后流至凹槽32的最低处，通过排水孔34将凹槽32最低处的水直接向外排出，如此，避免了凹槽32中水满溢出时，水可能会向盒体1内部溢出的现象，这样有效降低了雨水进入电池盒70对电池包7造成影响的可能。
在一种可行的实施方式中，如图5所示，盒体1可以包括设置在密封机构的内侧的导水机构，导水机构能承接自密封机构处泄露至盒体1中的水。所述导水机构可以包括：设置在盖体2的内壁与底座3相闭合处的具有沟槽81的导水件8。导水件8的沟槽81能承接自第一端面31和第二端面21相贴处泄露至盒体1中的水。导水件8位于第一端面31和第二端面21相贴处附近。具体而言，导水件8的一侧可以与盖体2内壁相固定连接，导水件8的另一侧位于底座3一侧并能与底座的内壁相抵，导水件8的沟槽81位于导水件8朝向底座3或盖体2的一侧，以使导水件8两侧之间形成的沟槽81能承接自第一端面31和第二端面21相贴处泄露至 盒体1中的水。导水件8可以由橡胶、塑料等材料制成，其具有一定的韧性和弹性。在一种可行的实施方式中，导水件与盖体之间可以一体成型。当盖体2进行开启或关闭时，不会对盖体2与底座3之间的配合造成影响。导水件8的另一侧位于底座3一侧，且不与底座3相连接，如此，盖体2与底座3之间能够实现自由开启或关闭。当盖体2开启时，若底座3的凹槽32中残留有水，水在盖体2的带动下会被带出凹槽32，此时，由于下方具有导水件8，水会掉落至导水件8中，不会直接掉落至盒体1内部的电池包7上，如此也可以在一定程度上避免雨水等进入盒体1内部对电池包7造成短路影响。另外，当雨水从第一端面31和第二端面21相贴处泄露至盒体1中时，雨水都会掉落至导水件8中，不会直接掉落至盒体1内部的电池包7上。
如图3所示，为了排出导水件8沟槽81中承接的自第一端面31和第二端面21相贴处泄露至盒体1中的水，底座3上的排水孔34也可以与导水件8的最低处的沟槽81相连通，沟槽81中积攒的水会沿着沟槽81向低处流动，从而流至排水孔34中排出，如此可以避免导水件8沟槽81中的水过多后溢出进入盒体1内部。
如图1至图3所示，盒体1的底座3中可以具有用于对电池包7起到支撑和限位作用的支撑限位部。在一种可行的实施方式中，支撑限位部可以位于盒体1的中部，沿竖直方向延伸，从而将盒体1隔开形成两个区域，每个区域可以安装一个电池包7，每一个电池包7都紧靠着支撑限位部，同时，部分盒体1的端面与电池包7之间的间隙较小，也可以对电池包7进行限位，如此可以保证安装后的电池包7的稳定性。例如，底座3的后端面和盖体2的前端面均与电池包7之间的间隙较小，进而对电池包7进行限位。同时，第一挡水件5和第二挡水件6的内侧壁与电池包7之间的间隙较小，也可以对电池包7进行限位。在上述实施方式中，电池包7可以呈水平方向的左右并列设置，当然，支撑限位部的数量可以更多，以使可容纳电池包7的数量更多，电池包7依旧可以呈水平方向并列设置。
图7为电池盒安装在电瓶车上的第二种实施方式，如图7所示，在一种可行的实施方式中，支撑限位部可以位于盒体1的中部，沿水平方向延伸，从而将盒 体1隔开形成上下两个区域，每个区域可以安装一个电池包7。在上述实施方式中，电池包7可以沿竖直方向上下设置。在其它实施方式中，例如电池包7为四个时，电池包7可以同时呈水平方向的左右并列设置和沿竖直方向上下设置，即水平方向并列设置两个，竖直方向上设置两个。
如图1至图5所示，电池包7设置在盒体1的容纳腔室内，电池包7与盒体1之间可拆卸连接。盒体1的底座3上可以安装有插接件，当电池包7***至底座3中时，电池包7与插接件相对接，以实现将电池包7的电流通过插接件向外输出。电池包7可以为多个，多个电池包7之间可以以并联或串联方式相连接。
如图4所示，底座3内部的底部形成有凹陷部35，凹陷部35围绕在电池包7四周，凹陷部35的最低处低于电池包7的底部。当雨水等万一进入至盒体1中时，雨水先会积攒在底座3的凹陷部35中，短时间内其不会接触到电池包7，如此在一定程度上可以提高电池包7的安全性。
在本申请中还提出了一种电动车，电动车包括如上述任一的电池盒70。电池盒70可以固定安装在电动车的某些不碍事的位置或部件上。该电池盒70用于给电动车进行供电，电池盒70中的插接件通过导线连接与电动车的耗电部件相电性连接。当电池盒70中电池包7电量耗尽时，可以将盖体2打开，从而方便的将电量耗尽的电池包7取出，再安装入准备好的电量满的电池包7，如此，电动车就能够继续使用行使，避免了电瓶车在没电时，必须停下来来充电的问题。
图6为电池盒安装在电瓶车上的第一种实施方式，如图6所示，电池盒70安装在电动车的立管10上，其可以安装在靠近骑行者一侧，也可以安装在远离骑行者一侧，在该实施方式中，电池盒70内的电池包7为两个左右并列设置的。如图7所示，电池盒70安装在立管10上，在该实施方式中，电池盒70内的电池包7为两个沿竖直方向上下设置的，同样的，其可以安装在靠近骑行者一侧，也可以安装在远离骑行者一侧。图8为电池盒安装在电瓶车上的第三种实施方式，图9为电池盒安装在电瓶车上的第四种实施方式，如图8和图9所示，电池盒70安装 在电动车的斜管20上，电池盒70内的电池包7可以为两个左右并列设置的，也可以为两个沿竖直方向上下设置的。图10为电池盒安装在电瓶车上的第五种实施方式，如图10所示，电池盒70安装在电动车的车架30上方，在该实施方式中，电池盒70可以为两个，每一个电池盒70中安装一个电池包7，电池盒70分别位于斜管20的左侧和右侧。图11为电池盒安装在电瓶车上的第六种实施方式，如图11所示，电池盒70安装在电动车的车架30下方，电池盒70中的电池包7可以沿竖直方向上下设置，但整个电池盒70水平后安装到电动车的车架30下方。图12为电池盒安装在电瓶车上的第七种实施方式，图13为电池盒安装在电瓶车上的第八种实施方式，图14为电池盒安装在电瓶车上的第九种实施方式，如图12至图4所示，该电瓶车可以是E-bike类型，电池盒70可以安装在电动车车架的上管40或车架的下管50或车架的立管60上。
在一种可行的实施方式中，电池包可以沿水平方向或沿垂直方向或沿与垂直方向呈0至60度夹角的方向***至电池盒中，如此，可以便于电池包更换时***至电池盒中。
