Description

一种电动平衡车 技术领域
本发明涉及便携交通工具领域，特别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、摄位车等；
市场上主要有独轮和双轮两类，其运作原理主要是建立在一种被称为“动态稳定”(Dynamic Stabilization)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；是现代人用来作为代步工具、休闲娱乐的一种新型的绿色环保的产物；
而其驾驶方法如下：
类似人体自身的平衡系统，当身体重心前倾时，为了保证平衡，需要往前走，重心后倾时同理，转向时，如果平衡车有类似把手的结构，则控制把手即可，类似汽车的方向盘，如果只是独轮的电动平衡车，则根据需求像两侧不同程度地倾斜身体即可；
如此优秀的产品，如今为何普及率不高，除了学习成本太高以外，还有就是电动平衡车的安全性很差，实际使用中很可能会摔伤甚至有生命危险；
比如，驾驶者驾驶平衡车途中，遇到一个小坑，轮子在行驶过程中瞬间被卡入了坑中，按照原理来说，驱动轮子转动的电机还在工作的情况下，轮子相对于平衡车主体车架(和支撑驾驶者的部分一体的，比如脚踏板)还是会相对 转动，理论上是可以把车架往后旋转带动驾驶后反弹回正常位置的，但是实际上没有这么大驱动力的电机，现在的工业水平这种产品还做不出来，其次，这个反向旋转的“反应时间”也是一个很现实的问题，这两个原因决定了现在的电动平衡车驾驶实际上是非常危险的。
发明内容
本发明的目的在于克服现有技术中所存在的上述不足，提供一种提高驾驶安全性的电动平衡车。
为了实现上述发明目的，本发明提供了以下技术方案：
一种电动平衡车，其包括：
主体架；
车轮，所述车轮可转动地与所述主体架相配接，并由动力源驱动转动；
支撑装置，所述支撑装置用于支撑驾驶者，所述支撑装置安装于所述主体架上；
(到这里为止，基本是现有的电动平衡车所包含的结构，包括双轮的、单轮的电动平衡车)；
其还包括连接装置、蓄能轮；
所述支撑装置通过所述连接装置和所述主体架连接，所述支撑装置和所述主体架分别与所述连接装置上的两个错开布置的连接点连接，形成两个转动副，所述主体架与所述连接装置连接形成的转动副的公共轴线与所述车轮的中心轴线重合，所述支撑装置和所述连接装置连接形成的转动副被构造为满足所述支 撑装置能够朝向所述车轮的前方或后方转动；
所述蓄能轮安装于所述支撑装置上，由动力源驱动转动，并在所述电动平衡车行驶过程中保持转动，所述蓄能轮被构造为满足当所述支撑装置相对竖直方向倾斜一定角度后，所述蓄能轮能够与所述车轮或所述主体架接触，通过所述蓄能轮的转动动能使所述支撑装置往所述竖直方向回转。
和现有技术相比，采用了一种新的结构：蓄能轮；
基本原理就是运用蓄能轮的转动提前储存当出现背景技术中的情况时那一瞬间所需的使支撑装置回转的能量，从而保护驾驶者的安全；
由于这个特殊的设定，所以配套设定了新的连接方式，加入了所述连接装置，连接处为2个转动副，且使支撑装置的转动和车轮(或主体架)的转动不同心，提前设定好蓄能轮的位置，那么支撑装置转动到一定角度时，必然接触所述车轮或所述主体架，这时蓄能轮的转动动能在一瞬间被释放，带动支撑装置回转，从而带动驾驶者回转，避免驾驶者飞出的情况出现，提高驾驶安全性。
作为本发明的优选方案，所述两个转动副具体为：
所述连接装置的一端与所述支撑装置铰接，形成第一铰接点，即形成一个所述转动副，所述连接装置的另一端与所述主体架铰接，形成第二铰接点，即形成第二个转动副，所述第二铰接点中心位于所述车轮的中心轴线上；在转动副的选择中，铰接算是比较稳定的一种方案。
作为本发明的优选方案，所述连接装置安装在所述主体架两侧，均为一单个的连接件，结构比较简单，优化更好，但是当两个所述转动副出现问题的时候，比如生锈卡住的时候，比较危险。
作为本发明的优选方案，所述连接装置安装在所述主体架两侧，所述连接装置由若干个连接件转动连接构成，结构相对一个连接件的形式更复杂，但是当两个所述转动副出现问题的时候，比如生锈卡住的时候，可以有效的把转动副的转动中心转到最近的连接件和连接件的转动连接处，防止卡死的情况。
作为本发明的优选方案，所述车轮数量为1个，所述支撑装置向上延伸，具备用于挡在驾驶者前方的挡块，车轮数量为1个情况下，为独轮的电动平衡车，挡块的设置可以更好地帮助支撑装置往竖直方向回转时把驾驶者带回。
作为本发明的优选方案，所述车轮数量为2个，所述支撑装置向上延伸，具备用于挡在驾驶者前方的挡块，车轮数量为2个的情况下，为双轮的电动平衡车。
作为本发明的优选方案，所述支撑装置包括：
主支撑架，所述连接装置和所述主支撑架形成所述转动副；
踏板，所述踏板设置在所述主支撑架上，位于所述主体架的两侧。
作为本发明的优选方案，单个的所述踏板和所述连接装置之间连接有弹性构件，所述弹性构件分别位于所述主支撑架的两侧，用于提供使所述支撑装置往所述竖直方向回转的阻尼，在本申请技术方案中，电动平衡车使用时，还是需要驾驶者自身尽量保证支撑装置的平衡，实际使用中，道路也不可能完全的平整，再加上本身主体架和车轮间存在的摩擦，所以支撑装置会在一定程度上受到影响产生偏转，而所述弹性构件提供的所述阻尼(弹性构件的弹力所产生)可以起到修正作用，减小驾驶者的驾驶难度，提高驾驶体验。
作为本发明的优选方案，驱动所述车轮转动的动力源为转子电机，相对于 其他电机来说，在电动平衡车中更普遍，使电动平衡车的重心也更好控制。
作为本发明的优选方案，所述蓄能轮具备加速旋转的功能，加速旋转时，蓄能轮就具备了陀螺仪的进动性，该性能可以帮助电动平衡车具备更好的平衡性能，使驾驶者能够更稳定地且更容易地驾驶电动平衡车，一定程度上提高驾驶安全性能以及降低学习成本。
作为本发明的优选方案，所述连接装置为T型结构，所述第一铰接点和第二铰接点均位于所述T型结构中间的长条形结构上，采用对称结构的连接件，可以进一步提高电动平衡车的稳定性，同时T型结构中向两侧支出的长条形结构上也方便对称安装其他部件(如所述弹性构件)，最大限度的保证电动平衡车整体的中心位置最优，提高电动平衡车的稳定性，同时也间接地提高了驾驶安全性。
作为本发明的优选方案，所述弹性构件的一端连接在所述踏板上，另一端连接在所述T型结构向两侧支出的长条形结构上，所述主支撑架竖直状态下，所述弹性构件对称布置在所述主支撑架的两侧，弹性构件的设置和T型结构的结合，在保证对支撑装置前后倾斜的一定修正效果的情况下，也尽量的满足了电动平衡车整体的对称型，保证其重心位置最优，提高电动平衡车的稳定性，同时也间接地提高了驾驶安全性。
与现有技术相比，本发明的有益效果：
提高电动平衡车的驾驶安全性。

所述连接装置9安装在所述主体架2两侧，均为一单个的连接件(在本实施例的结构中，所述连接装置9还可由若干个连接件转动连接构成，是一种更复杂但是有一定有益效果的技术方案)；所述连接装置9为T型结构，所述第一铰接点和第二铰接点均位于所述T型结构中间的长条形结构上，所述第二铰接点高于所述第一铰接点，其实，由于重力原因，当整个结构装配完毕以后，所述连接装置9必然会自然旋转，第一铰接点和第二铰接点同时位于一个竖直直线上，第一铰接点在最低处；
所述支撑装置8包括：
主支撑架7，所述连接装置9和所述主支撑架7形成所述转动副；
踏板6，所述踏板6设置在所述主支撑架7上，位于所述主体架2的两侧；
本实施例中，所述主支撑架7侧面固定连接有一个用于安装所述蓄能轮4的安装架3，所述蓄能轮4安装在所述安装架3的端部，本实施例中，所述安装架3支出所述主支撑架7的长度被构造为使所述蓄能轮4接触所述主体架2而产生作用(本实施例中，所述安装架3也能够设置为往车轮10的前后两个方向支出，对应2个蓄能轮4，如图6，按照前面的说法，靠电动平衡车后方的轮子 逆时针旋转，靠电动平衡车前方的轮子顺时针旋转，这种结构下，则不需要把结构设计成使蓄能轮4接触车轮10了，遇到有坑的情况，通过靠后的蓄能轮4和主体架2接触即可，遇到刹车的往后仰的情况，通过靠前的蓄能轮4和主体架2接触即可)。
单个的所述踏板6和所述连接装置9之间连接有弹性构件5，所述弹性构件5分别位于所述主支撑架7的两侧，用于提供使所述支撑装置8往所述竖直方向回转的阻尼。
具体的，所述弹性构件5的一端连接在所述踏板6上，另一端连接在所述T型结构向两侧支出的长条形结构上，所述主支撑架7竖直状态下，所述弹性构件5对称布置在所述主支撑架7的两侧，本实施例中，所述弹性构件5为弹簧；
在行驶过程中，当遇到坑时，如背景技术中所述的情况，车轮10卡入坑中，如图3，此时，图中竖直的点画线表示竖直方向，遇到坑时，整个支撑装置8往前倾斜，倾斜到图中角度时，旋转的蓄能轮4接触到主体架2(按照本实施例图中的设置方式，以图3作为参考，蓄能轮4是逆时针方向旋转)，然后在一瞬间释放旋转的动能，带动整个支撑装置8往竖直方向回转，从而保护驾驶者不甩出去；
同样的，以图3作为参考，蓄能轮4逆时针方向旋转，在需要刹车的时候，比如急刹，如图4，在往后倾斜后，电动平衡车识别进行减速后，当速度减下来时，现有的电动平衡车是不会给予支撑装置8一个使其回转的力的，那么在倾斜到一定角度后，驾驶者就有可能往后摔倒，造成伤害，如图4，本实施例的蓄能轮4的设置，在往后倾斜到一定角度时，旋转的蓄能轮4接触到停止的车轮10，然后在一瞬间释放旋转的动能，带动整个支撑装置8往竖直方向回转，从 而保护驾驶者不往后摔倒。
实施例2
如图7，本实施例中，除了和实施例1中的结构相同的技术方案以外，所述车轮10数量为2个，为双轮的电动平衡车，包含2个主体架2，两个主体架2对称设置，通过所述支撑装置8连接，而所述支撑装置8分别与所述主体架2通过所述连接装置9连接，和实施例1一样，单侧的连接均形成2个所述转动副，这种设置的话，实施例1中的踏板6则为一个了，设置在两个车轮10之间。
实施例3
如图8，本实施例中，除了和实施例1中的结构相同的技术方案以外，所述安装架3支出所述主支撑架7的长度被构造为使所述蓄能轮4接触所述车轮10外圈而产生作用，具体的是直接从踏板6向外延伸，构成所述安装架3(本方案中蓄能轮4设置在后方，蓄能轮4的旋转方向就是以图8为标准，顺时针转动了)，所述蓄能轮4到车轮10中心的距离在未接触情况下大于车轮10的半径，(本实施例中，所述安装架3也能够设置为往车轮10的前后两个方向支出，对应2个蓄能轮4，如图9，靠前的蓄能轮4则逆时针转动)。
实施例4
如图10，本实施例中，除了和实施例3中的结构相同的技术方案以外，所述车轮10数量为2个，为双轮的电动平衡车，包含2个主体架2，两个主体架2对称设置，通过所述支撑装置8连接，而所述支撑装置8分别与所述主体架2通过所述连接装置9连接，和实施例3一样，单侧的连接均形成2个所述转动副，这种设置的话，实施例3中的踏板6则为一个了，设置在两个车轮10之间。
实施例5
如图11、12，本实施例中，除了和实施例1中的结构相同的技术方案以外，所述安装架3则设置在所述连接装置9顶部的挡块1的相对于电动平衡车的前后两侧，对应的前后均安装有蓄能轮4，该实施例的技术方案和实施例3中的图9中的情况类似，只是把蓄能轮4设置在了车轮10的上方，主支撑架7上的挡块1则被设置为了一个座位，而两个蓄能轮4则设置在座位上，后方的蓄能轮4则逆时针转动，前方的蓄能轮4则顺时针转动；
如图13，遇到坑时，支撑装置8向前倾斜，则相对的位于电动平衡车后方的蓄能轮4接触到车轮10的外沿，带动支撑装置8往竖直方向回转，刹车情况如图14，撑装置向后倾斜，则相对的位于电动平衡车前方的蓄能轮4接触到车轮10的外沿，带动支撑装置8往竖直方向回转。
实施例6
如图15，本实施例中，除了和实施例5中的结构相同的技术方案以外，所述车轮10数量为2个，为双轮的电动平衡车，包含2个主体架2，两个主体架2对称设置，通过所述支撑装置8连接，而所述支撑装置8分别与所述主体架2通过所述连接装置9连接，和实施例5一样，单侧的连接均形成2个所述转动副，这种设置的话，实施例5中的踏板6则为一个了，设置在两个车轮10之间。
