技术领域technical field

背景技术Background technique
编码器是设置在驱动轮轴上，用于检测驱动轮的转动，记录驱动轮转动的圈数，可以用来计算智能割草机行走的里程，编码器的固定安装方式，通常有以下两种方式：螺钉连接或粘胶连接。The encoder is set on the drive wheel shaft to detect the rotation of the drive wheel and record the number of turns of the drive wheel, which can be used to calculate the mileage of the smart lawn mower. The fixed installation method of the encoder usually has the following two methods. : Screw connection or glue connection.
但螺钉连接会增加零件(增加螺钉和连接套)，成本提高，连接套会增大轴向厚度，导致轮毂电机较厚，径向上，由于需要做螺钉定位孔，编码器需要向外延展，径向尺寸增大，从而需要选择更大尺寸的支撑轴承，导致体积大且成本高；组装工序较多，装配及返修工时长；粘胶连接是使用胶水将编码器PCB粘接在钢片或者线包上，而胶水的固化需要一定的时间，工时成本高，且PCB粘在钢片或者线包上，PCB的平整度及位置精度比较低，维修更换麻烦，胶水可靠性及工艺的稳定性不一致。However, the screw connection will increase the number of parts (adding screws and connecting sleeves), and the cost will increase. The connecting sleeve will increase the axial thickness, resulting in a thicker hub motor. In the radial direction, due to the need to make screw positioning holes, the encoder needs to be extended outwards. As the size increases, it is necessary to choose a larger size support bearing, resulting in large volume and high cost; more assembly processes, long assembly and rework time; glue connection is to use glue to bond the encoder PCB to the steel sheet or wire However, the curing of the glue takes a certain amount of time, the labor cost is high, and the PCB is glued to the steel sheet or the wire package, the flatness and position accuracy of the PCB are relatively low, the maintenance and replacement are troublesome, and the reliability of the glue and the process stability are inconsistent. .
