Since the connection method is point contact, poor contact is prone to occur. In addition, when the PCB board is in contact with the motor, the heat dissipated by the motor will cause the electronic components of the PCB board to age and fail, resulting in a reduction in the service life of the PCB board. The PCB board needs to be disassembled and replaced frequently. Utility Model Content

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figures 1 to 5As shown, the utility model can be implemented through the following embodiments: a motor with an electric control board includes a motor body 1 and a mounting shell 2, the mounting shell 2 is installed on the rear end surface of the motor body 1, a mounting plate 21 is arranged in the mounting shell 2, a PCB board 3 is installed on the mounting plate 21, a wiring port 31 is arranged on the PCB board 3, a connecting wire 4 is connected to the wiring port 31, a connecting end 11 is arranged on the rear end surface of the motor body 1, a connecting groove 22 matching the connecting end 11 is arranged on the mounting shell 2, a terminal 111 is arranged in the connecting end 11, an end 41 of the connecting wire 4 is connected to the terminal 111, and the mounting shell 2 and the motor body 1 are fixedly connected by bolts 5.

[0022] By setting the PCB board 3 on the mounting plate 21 of the mounting shell 2, the PCB board 3 is prevented from being subjected to the high temperature conducted by the motor, which may cause failure of the electronic components on the PCB board 3, and a wiring port 31 is set on the PCB board 3, and a connecting terminal 11 is set on the motor body 1 for connecting the wiring port 31 and the connecting terminal 11 through a connecting line 4.

[0023] like Figure 1 to Figure 2 As shown, the mounting shell 2 is made of plastic, and the mounting plate 21 is made of metal. The mounting shell 2 made of plastic has low thermal conductivity, which prevents the heat of the motor from being transferred to the PCB board 3 through the mounting shell 2. The mounting plate 21 is made of metal so that the PCB board 3 can dissipate its own heat through the mounting plate 21.

[0024] like Figure 1 and Figure 2 As shown, a plurality of ventilation slots 231 are provided on the first shell wall 23. The ventilation slots 231 are provided to allow external air to enter the mounting shell 2 for heat dissipation.

[0025] like Figure 2 As shown, the shell wall of the mounting shell 2 is divided into a first shell wall 23 and a second shell wall 24, and a ventilation layer 25 is provided between the first shell wall 23 and the second shell wall 24. The first shell wall 23 is used to connect with the motor, and the second shell wall 24 is provided with a mounting plate 21. The ventilation layer 25 is provided to dissipate the heat in the mounting shell 2.

[0026] like Figure 2 As shown, the first shell wall 23 and the second shell wall 24 are combined at the mounting plate 21, and the mounting plate 21 is provided with a heat sink 211 that penetrates the first shell wall 23 and the second shell wall 24. The combination of the first shell wall 23 and the second shell wall 24 at the mounting plate 21 facilitates the installation of the mounting plate 21 and enhances the strength of the mounting shell 2. The heat sink 211 is provided to contact the mounting plate 21 with the outside air and improve the heat dissipation efficiency of the mounting plate 21.

[0027] like Figure 2 and Figure 4As shown, the connection end 11 is plugged with a fixing plate 6, and a through hole 61 is provided on the fixing plate 6, through which the terminal 111 passes. The through hole 61 on the fixing plate 6 is used to limit the insertion position of the terminal 41 to improve the installation efficiency. The fixing plate 6 fixes the terminal 41 on the fixing plate 6 to improve the connection stability between the connecting wire 4 and the connection end 11.

[0028] like Figure 4 and Figure 5 As shown, a buckle 611 is provided at the through hole 61, and a corresponding slot 411 is provided at the terminal 41. The buckle 611 and the slot 411 are provided to enhance the connection stability between the terminal 111 and the terminal 41, and prevent the terminal 41 and the terminal 111 from having poor contact due to vibration when the motor is working.

[0029] like Figure 3 and Figure 5 As shown, the terminal 111 and the end 41 are configured as a cuboid, and the end 41 is provided with an interface 412 corresponding to the shape of the terminal 111. The cuboid design enables the contact between the terminal 111 and the end 41 to be in surface contact, greatly improving the connection stability between the terminal 111 and the end 41.

[0030] The working principle of the utility model is as follows: the PCB board 3 is installed on the mounting plate 21, the connecting wire 4 is connected to the wiring port 31 through the second shell wall 24, and then the end 41 of the connecting wire 4 is connected to the terminal 111 of the motor body 1, the buckle 611 on the fixing plate 6 fixes the end 41 through the slot 411 on the end 41, and finally the mounting shell 2 and the motor body 1 are fixedly connected by the bolt 5.

[0031] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0032] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
