Description

一种电动车一体式后悬挂支承定位结构 技术领域
本发明涉及定位结构技术领域，尤其涉及一种电动车一体式后悬挂支承定位结构。
背景技术
电动车后桥，就是指车辆动力传递的后驱动轴组成部分。它是由两个半桥组成，可实施半桥差速运动。同时，也是用来支撑车轮和连接后轮的装置。
众所周知，电动车作为一种交通代步工具，在日常生活中被广泛应用，其中后桥总成在电动车中承担支撑车轮和连接后轮的任务，同时还起到驱动和减速的作用。在后桥组成的焊接组装过程中，通过将钢板弹簧座焊接在后桥总成上，用于支撑钢板弹簧。通过钢板弹簧来消减电动车行驶时的剧烈振动，使车辆在行驶时能够保持平稳。
为加强电动车行驶过程中的平稳性，一般电动车后桥总成上按照对称的形式安装钢板弹簧，这样就会需要钢板弹簧座对称焊接在后桥总成上。由于钢板弹簧座是焊接在后桥桥管上，在焊接时经常会出其中一个钢板弹簧座或两个钢板弹簧座同时出现焊接倾斜的情况，便会导致桥管上焊接的钢板弹簧座不处于同一水平线上，从而影响钢板弹簧的安装。

本申请实施例中提供的一个或多个技术方案，至少具有如下技术效果或优点：
1、先将定位块之间的距离调整到最大，再将固定框套在支承件上，转动转杆，将推板向支承件的方向推动，推板紧贴支承件后，停止转动转盘，接着转动螺纹杆，定位块向相对方向移动，将支承件固定；固定框发生移动时，将支撑板卡合在安装座上，然后向下拽动伸缩杆，使安装座底端面和支撑板底端面同时与加工平面接触，将伸缩杆的位置固定，然后保持连接件左端的固定框不动，向相反方向拉动连接件右端的固定框，连接绳端头受到拉力使连接绳被拉出，从而实现固定框之间的距离调整；通过该定位结构将后悬挂支承件对称焊接在后桥桥管上时，确保两组所述固定框能够在同一水平线上进行移动，使得两组所述固定框相对于加工平面平行，保证后桥桥管上焊接的后悬挂支承件 能够处于同一水平线上，避免后悬挂支承件在焊接定位时其中一个后悬挂支承件或两个后悬挂支承件同时出现倾斜，从而造成中心偏移的情况出现。
2、安装轴插入卷筒上的轴孔内，然后转动弧形固定板使安装孔二的位置与连接件上的连接孔对应，接着插入插销使其贯穿连接孔插入卷筒上，从而限制卷筒的转动，实现固定框之间的距离固定；使该连接件在连接绳拉出后实现限位，使调整距离后的固定框位置能够固定，不会出现突然复位的情况。

实施例一
请参阅图1-5，一种电动车一体式后悬挂支承定位结构，包括后悬挂支承件10、定位结构20、连接件30和后桥桥管40；
所述后桥桥管40可拆卸安装于电动车车体上，用于后桥总成的组成部件；
所述后悬挂支承件10焊接固定于后桥桥管40上，且后悬挂支承件10成对使用，分别焊接在后桥桥管40左右两侧上，用于实现钢板弹簧和后桥调节拉杆吊耳一体式支承；
所述定位结构20可拆卸连接于后悬挂支承件10上，用于后悬挂支承件10 的焊接定位，确保后桥桥管40上焊接的后悬挂支承件10处于同一水平线上，避免后悬挂支承件10在焊接定位时出现倾斜，从而造成中心偏移的情况出现；
所述定位结构20包括固定框220、推板210、调节件230、定位块240、螺纹杆250、限位块260和把手270；
所述固定框220设有两组，分别用来固定后悬挂支承件10，确保后悬挂支承件10焊接在后桥桥管40上的稳定性，焊接时避免倾斜的情况出现；
所述推板210滑动连接于固定框220内部左右两端；
所述调节件230转动连接于左侧的推板210左端，且调节件230相对于固定框220对称转动连接于右侧的推板210右端，用于调节推板210在固定框220内的位置，使推板210实现位置移动；
所述定位块240滑动套接于推板210上下两侧上；
所述螺纹杆250转动连接于定位块240之间，且螺纹杆250位于推板210上方，用于调节定位块240在推板210上的位置，使定位块240实现位置移动；
所述限位块260固定套接于螺纹杆250的中间位置上；
所述把手270固定连接于螺纹杆250上端，且把手270位于固定框220上端外部，用于实现螺纹杆250转动；
所述连接件30固定连接于两组固定框220之间，用于调整两组固定框220之间的距离，以便后悬挂支承件10在焊接时能够位于同一水平线上。
所述调节件230包括转杆231和转盘232；
所述转杆231转动连接于推板210左端，且转杆231贯穿固定框220并延伸至固定框220左端外部，用于推动推板210在固定框220内滑动；

所述固定框220左右两侧的外壁上开设螺纹孔，且该螺纹孔的深度贯穿固定框220的外壁，呈通孔设计，用于实现与转杆231之间的转动连接。
所述螺纹杆250上设有两种螺纹方向，由于限位块260固定套接于螺纹杆250上，由此以限位块260为界限，所述限位块260左端的螺纹杆250上螺纹 方向顺时针设置，所述限位块260右端的螺纹杆250上螺纹的方向逆时针设置，当顺时针转动把手270时，推板210上的定位块240顺着螺纹杆250向相对方向转动，逆时针转动把手270时，推板210上的定位块240顺着螺纹杆250向相反方向转动。
所述推板210上定位块240之间的最大尺寸距离(也就是定位块240分别同时位于推板210的上下两端)比后悬挂支承件10的横向长度距离大1-2cm，在将固定框220固定在后悬挂支承件10上时，先将定位块240之间的距离调整到最大，其次调整推板210的位置，使其向后悬挂支承件10的方向靠近，使推板210紧贴支承件，最后转动把手270，使定位块240向相对方向移动，将支承件固定即可。
本申请实施例实际运行时，当后悬挂支承件10需要焊接在后桥桥管40上时，由于后悬挂支承件10需要对称焊接，将固定框220安装在后悬挂支承件10之前，先将定位块240之间的距离调整到最大(也就是定位块240分别同时位于推板210的上下两端)，然后将固定框220分别套在后悬挂支承件10上，顺时针转动转盘232，使转杆231转动，由此将推板210向后悬挂支承件10的方向推动，当推板210紧贴支承件外表面时，停止转动转盘232，紧接着顺时针转动把手270带动螺纹杆250发生转动，使定位块240顺着推板210向相对方向移动，将后悬挂支承件10固定在定位块240之间，停止转动把手270，保持连接件30左端的固定框220位置不动，这时只需拉动连接件30右端的固定框220，使其顺着后桥桥管40移动，将其拉到合适的位置即可停止，然后将后悬挂支承件10焊接在后桥桥管40左右两侧上即可。
上述本申请实施例中的技术方案，至少具有如下的技术效果或优点：
通过该定位结构将后悬挂支承件对称焊接在后桥桥管上时，确保后桥桥管上对称焊接的后悬挂支承件能够处于同一水平线上，避免后悬挂支承件在焊接定位时其中一个后悬挂支承件或两个后悬挂支承件同时出现倾斜，从而造成中心偏移的情况出现。
实施例二

所述操作杆320可拆卸连接于连接件30前表面上，用于限制卷筒330的转动；
所述连接绳端头310固定连接于安装底座300上，且连接绳端头310与卷筒330之间通过连接绳转动连接。
所述连接绳端头310的上端延伸至连接件30的上表面上侧，且连接绳端头310上端与右侧的固定框220左端外壁焊接固定，用于实现两组所述固定框220之间的连接。
所述卷筒330的工作原理同卷尺类似，具有能够自动回位的回复力，且卷筒330上卷绕连接绳，连接绳的长度可以根据需求自己裁定。
所述操作杆320包括手柄321、安装头322、连接部323、安装轴324、弧形固定板325和安装孔二326；

当连接绳拽出后，两组所述固定框220之间的距离逐渐增加，将固定框220之间的距离调整到合适的位置，为了防止连接绳自动收缩回去，通过操作杆320限制卷筒330转动，从而将固定框之220间的距离固定。
本申请实施例实际运行时，当固定框220固定在后悬挂支承件10上后，如果需要调整固定框220之间的距离，这时，保持连接件30左端或右端的固定框220位置固定，拉动另一端的固定框220使其向相反方向移动，连接绳端头310受到拉力使连接绳被拉出，从而实现固定框220之间的距离调整，为了防止连接绳自动收缩回去，通过手柄321将安装轴324插入卷筒330上的轴孔内，然后转动弧形固定板325使安装孔二326的位置与连接件30上的连接孔对应，接着插入插销使其贯穿连接孔插入卷筒330上，从而限制卷筒330的转动，实现固定框220之间的距离固定。
上述本申请实施例中的技术方案，至少具有如下的技术效果或优点：
通过该连接方式不仅实现固定框之间的距离调整，更是增加了该连接方式的调整距离，提高连接件的适配性；同时具备限位的作用，使调整距离后的固定框位置能够固定，不会出现突然复位的情况。

本申请实施例实际运行时，当固定套接在后悬挂支承件10上的固定框220发生移动时，通过连接件30虽然实现了固定框220之间的连接，但固定框220移动时难保不会出现倾斜的问题，这时，就需要调整调节柱280的长度，首先，将支撑板284卡合在安装座283上，然后向下拽动伸缩杆281，使安装座283底端面和支撑板284底端面同时与加工平面相接触后，插销插入固定孔二282内，将伸缩杆281的位置即可，特别要注意的是，两组所述固定框220的调节柱280上下调整的距离一样(也就是说伸缩杆281伸出或缩短的长度是一样的)。
上述本申请实施例中的技术方案，至少具有如下的技术效果或优点：
通过该调节柱，确保两组所述固定框是在同一水平位置高度上，使得两组所述固定框相对于加工平面平行，实现了两组所述固定框能够在同一水平线上进行移动，从而确保后悬挂支承件在焊接时是处于同一水平线上的。
