该新型车头摇摆机构，由一主轴和一摇摆壳体以及设置在摇摆壳体内部的摇摆锁止机构和摇摆限位结构，主轴的后端固定在车后体上，主轴的前端设置在摇摆壳体内部并且与摇摆壳体转动连接，而摇摆壳体可以绕主轴往复摆动，摆动角度可达到±18°，也就是摇摆壳体可以绕主轴正反方向摆动18度，而摆动范围的限位和锁止是通过摇摆锁止机构和摇摆限位结构配合实现的。将该新型车头摇摆机构连接在车头与车后体之间，当车头转弯时，车头在摇摆壳体的带动下进行摇摆，辅助转向，减小转弯半径，避免转弯时车身倾斜或倾倒，增加了车体的平稳性和安全性。而当此时摇摆锁止机构处于非工作状态，即处于打开状态，保证三轮车的正常行驶，行驶结束需要驻车时，启动摇摆锁止机构，此时摇摆锁止机构与摇摆限位结构配合锁紧，摇摆锁止机构处于工作状态，固定车头位置，达到驻车状态。该新型车头摇摆机构，在行驶或原地转弯过程中，车头可以摇摆倾斜，车头摇摆角度目前可达±18°，实现了辅助车头转向的目 的，使车头的转弯半径减小，增加了车头的摇摆性能，从而提高了三轮车使用的安全性。
作为优选，所述的摇摆壳体通过设置在其内部的轴承件与主轴转动连接。车头摇摆是通过摇摆壳体带动实现的，为了保证摇摆壳体以主轴为中心顺利实现左右转动摇摆，摇摆壳体和主轴通过轴承件连接，摇摆效果好，结构简单。

作为优选，所述的摇摆限位件为一扇形板件，所述的摇摆限位件固定在主轴上并且摇摆限位件的扇面垂直于主轴的轴线设置；所述的摇摆限位件的扇面上沿弧长方向均布有多个限位卡槽。摇摆限位件设置呈一扇形板件，扇形板件套设固定在主轴上，摇摆壳体的摇摆角度由扇形的大小决定，扇形板件两侧的边缘在摇摆壳体往复摆动时会与摇摆壳体内侧设置的摇摆限位结构接触，实现限位，扇形越大摇摆角度越小，扇形越小则摇摆角度越大，本申请中摇摆壳体的角度设计为±18°。限位卡槽设置有多个，这样的结构是为了保证锁止件可以与其中任意一个进行卡接限位，保证了驻车时车头可以朝向任意方向或位置驻车，能够保证无论车头处于哪个位置都会有一个限位卡槽与锁止件配合限位。

摇摆壳体2，与整车中的车头软连接实现车头摇摆的摆动载体；
摇摆壳体2与主轴1密封转动连接，并且所述的摇摆壳体2以主轴1为中心绕主轴1往复摆动；摇摆壳体2内部设置有实现行车状态下车头摇摆和驻车状态下车头锁止的摇摆锁止机构3；摇摆壳体2上配合摇摆锁止机构3设置限制车头摇摆范围的摇摆限位结构4。摇摆限位结构4为设置在摇摆壳体2内壁上的两限位槽。
摇摆壳体2通过设置在其内部的轴承件5与主轴1转动连接。
摇摆锁止机构3包括摇摆限位件6、锁止件7和锁止件驱动机构8。
摇摆限位件6为一扇形板件，摇摆限位件6固定在主轴1上并且摇摆限位件6的扇面垂直于主轴1的轴线设置；摇摆限位件6的扇面上沿弧长方向均布有多个限位卡槽9。
锁止件7包括一转轴10和一转动臂11，转轴10的一端固定在摇摆壳体2上，转轴的另一端固定在锁止件驱动机构8上，转动臂11的一端与转轴10转动连接，转动臂11另一端为自由端，转动臂11的自由端上呈相反方向设置有一弧形凸台12和一限位卡齿13，限位卡齿13朝向摇摆限位件6设置。
锁止件驱动机构8包括驱动复位机构14、转动件15和摆压臂16，驱动复位机构14包括驱动件30和复位机构29，驱动件30和复位机构29分别与转动件15连接，所述的转动件15与摆压臂16的一端固定连接，摆压臂16的另一为自由端，摆压臂16的自由端呈弧形结构设置，摆压臂16的自由端朝向锁止件7设置并驱动锁止件7实现转动；复位机构29为弹簧复位组件；驱动件30为一驱动电机或驱动拉线。
本实施例中，驱动件为一驱动拉线，配合驱动件，本实施例中，锁止件驱动机构8包括驱动复位机构14、转动件15和摆压臂16(见图4)，驱动复位机构14包括驱动件30、驱动臂27、固定凸轮28和复位机构29，驱动臂的一端与 转动件15固定连接，驱动臂27的另一端设置有呈Y型结构设置有两夹紧体，夹紧体上设置有连接孔，驱动件30(本实施例中为一驱动拉线)与连接孔连接，夹紧体与复位机构29夹紧连接，转动件15穿过固定凸轮28与摆压臂16的一端固定连接，摆压臂16的另一为自由端，摆压臂16的自由端呈弧形结构设置，摆压臂16的自由端朝向锁止件7设置并驱动锁止件7实现转动；锁止件7与固定凸轮连接；复位机构29为弹簧复位组件；驱动件30为一驱动电机或驱动拉线。
在主轴上固定一扇形摇摆限位件6，在摇摆限位件6上设置多个限位卡槽，在限位卡槽的上方设置一带有限位卡齿13的转动臂11，限位卡齿朝向限位卡槽设置，在限位卡齿的另一侧的转动臂上设置弧形凸台，而转动臂通过一转轴分别与摇摆壳体和固定凸轮的下部连接，而转动件垂直穿设在固定凸轮的上部，转动件朝向转动臂的一侧连接有摆压臂，摆压臂的自由端与转动臂上的弧形凸台配合驱动转动臂上下运动；而复位机构与驱动臂连接，同时驱动臂与驱动件连接，当驱动件动作，驱动拉线拉紧或者驱动电机转动时，带动驱动臂向上(拉线拉紧的方向)转动，驱动臂带动转动件转动，同时带动复位机构向上拉紧，转动件的转动带动摆压臂向下运动，向下压下转动臂，使限位卡齿与限位卡槽啮合卡接，实现驻车锁紧。而当需要行车时，驱动件驱动电机反转或者驱动拉线松开，此时复位机构在弹簧的作用下复位，带动驱动臂向下运动复位，摆压臂向上运动，弧形凸台带动限位卡齿与限位卡槽脱开解锁，车辆可以正常行驶。
摇摆壳体2内部设置有含油橡胶阻尼件17。主轴1与摇摆壳体2之间通过一组密封件18密封连接。摇摆壳体2包括上壳体19和下壳体20，上壳体19和下壳体20内部形成密封腔21，摇摆锁止机构3设置在密封腔21内部，上壳体19外部的中部位置设置有带有橡胶衬套的中部软连接件结构22，下壳体20外 部的前端呈Y型对称设置有两个带有橡胶衬套的前端软连接结构23；主轴1上设置有后车体连接结构24，后车体连接结构24为一组连接轴销。
实施例2：
实施例2中的技术方案与实施例1中的技术方案基本相同，不同之处在于：驱动件采用的是驱动电机，配合驱动电机，锁止件驱动机构8包括驱动复位机构14、转动件15和摆压臂16，驱动复位机构14包括驱动件30和复位机构29，驱动件30和复位机构29分别与转动件15连接，所述的转动件15与摆压臂16的一端固定连接，摆压臂16的另一为自由端，摆压臂16的自由端呈弧形结构设置，摆压臂16的自由端朝向锁止件7设置并驱动锁止件7实现转动；复位机构29为弹簧复位组件。驱动电机正转带动转动件转动，转动件转动的同时带动复位机构动作，转动件带动摆压臂下压使限位卡齿与限位卡槽啮合卡紧。当驱动电机反转时，转动件带动摆压臂向上抬起限位卡齿与限位卡槽脱开，此时，复位机构复位使摆压臂处于抬起状态，可以安全行车。
上述实施例所述的新型车头摇摆机构，主要由一主轴1和一摇摆壳体2以及设置在摇摆壳体2内部的摇摆锁止机构3和摇摆限位结构4来实现，主轴1的后端固定在车后体26上，主轴1的前端设置有轴承件5，轴承件5固定在摇摆壳体2的密封腔21内部。摇摆壳体设置有上壳体和下壳体，上下壳体上设置有与车头25软连接的中部软连接件结构22和前端软连接结构23，通过三点连接的方式实现与车头的连接，保证摇摆的稳定性。而设置在摇摆壳体内部的摇摆锁止机构3包括有摇摆限位件6、锁止件7和锁止件驱动机构8，锁止件驱动机构8包括驱动件14、转动件15和摆压臂16，摇摆限位结构4为设置在摇摆壳体2内壁上的两限位槽。
摇摆限位件6为一扇形板件，扇形板件套设固定在主轴1的端部，扇形板 件的扇形边缘设置有扇边，扇边的厚度大于扇体的厚度，扇边的扇形面上设置有多个限位卡槽，扇边的扇形宽度决定了摇摆壳体的摇摆角度的大小，在摇摆壳体正反(左右)往复摇摆时，两边分别受限于摇摆壳体内部的摇摆限位结构4，即摇摆壳体内壁上的限位槽，实现对摇摆角度的限位。扇形越大摇摆角度越小，扇形越小则摇摆角度越大，本实施例中摇摆壳体的摇摆角度为±18°。为了保证锁止件上的限位卡齿13可以随车头驻车方向任意实现锁上定位，在摇摆限位件上的限位止槽设置有多个，保证了驻车时车头可以朝向任意方向或位置驻车，能够保证无论车头处于哪个位置都会有一个限位卡槽与锁止件配合限位。
锁止件驱动机构8中的驱动件可以是电机驱动，也可以是拉线驱动，本实施例中采用的是拉线驱动。驱动件动作，带动与之连接的转动件转动，转动件转动带动其上的摆压臂转动，摆动壁向下摆动时其上的弧形结构与锁止件的弧形凸台配合，通过弧形凸台带动转动臂向下运动，此时限位卡齿与摇摆限位件扇面上的限位卡槽卡接限位，实现锁止的功能。
如图5、图6所示，将该新型车头摇摆机构连接在车头25与车后体26之间，当车头转弯时，车头在摇摆壳体的带动下进行摇摆，辅助转向，减小转弯半径，避免转弯时车身倾斜或倾倒，增加了车体的平稳性和安全性。而当此时摇摆锁止机构处于非工作状态，即处于打开状态，保证三轮车的正常行驶，行驶结束需要驻车时，启动摇摆锁止机构，此时摇摆锁止机构与摇摆限位结构配合锁紧，摇摆锁止机构处于工作状态，固定车头位置，达到驻车状态。该新型车头摇摆机构，在行驶或原地转弯过程中，车头可以摇摆倾斜，车头摇摆角度目前可达±18°，实现了辅助车头转向的目的，使车头的转弯半径减小，增加了车头的摇摆性能，从而提高了三轮车使用的安全性。
该新型车头摇摆机构，在转弯时车头可以通过结合常规的转向和垂直于水 平面上的摇摆操作，在两种方式的协同作用下，达到灵活转向，即使大角度转弯也能应付自如，提高驾驶灵活度和便捷性，还能减少车体在转弯时的倾斜角度，特别是快递员驾驶的车上装有带汤汁的外卖时，能有效避免汤汁撒洒出，提高快递员的服务水平。此外，不同于常规的车头操作方式，在水平旋转基础上增加摇摆功能，能增加驾驶员的操作复杂度，提高驾驶员的注意力，有助于提升驾驶安全性，且车头摇摆角度设置有合理的最大角度可以避免操作复杂带来的危险。
