[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0035] In the present embodiment, a signal line connection structure of a motor 600 of an automotive actuator is provided. By changing the original hard connection method between the motor 600 and the circuit board, an electrical wiring harness 100 is selected to connect the motor 600 and the circuit board, and a stable plug-in assembly is provided to ensure that the motor 600 can obtain a stable power supply.

[0036] See also Figures 1 to 5 In this embodiment, a signal line connection structure of a motor 600 of an automobile actuator includes: an electrical wiring harness 100, a socket assembly 200 and a plug assembly 300.

[0037] One end of the electrical harness 100 is electrically connected to the motor 600. With the help of the electrical harness, the motor 600 can be flexibly connected to the power supply, which can resist bumps, vibrations and interference, and ensure the stability of the power supply of the motor 600.

[0038] The socket assembly 200 includes a harness socket 210 and a mounting seat 220. The mounting seat 220 is connected to the rear cover 400. The harness socket 210 is detachably connected to the mounting seat 220, and the harness socket 210 can be disassembled and replaced as needed. The two harness sockets 210 are electrically connected to the other end of the electrical harness 100, respectively. The two ends of the electrical harness 100 are connected to the motor 600 and the harness socket 210, respectively. The harness socket 210 is provided with a retractable elastic plug port 211. The harness socket 210 and the elastic plug port 211 can be used to control the on and off of the electrical harness 100.

[0039] The plug assembly 300 includes a plug-in terminal 310 connected to the front shell 500. The plug-in terminal 310 is arranged relative to the elastic plug-in interface 211. When the front shell 500 is docked with the rear cover 400, the plug-in terminal 310 can be just inserted into the elastic plug-in interface 211 of the harness socket 210, so as to realize the electrical connection between the plug-in terminal 310 and the harness socket 210 and provide electric energy for the motor 600. The plug-in terminal 310 and the harness socket 210 are connected to the front shell 500 and the rear cover 400 respectively. The fixed connection between the front shell 500 and the rear cover 400 can prevent the plug-in terminal 310 from being disengaged from the harness socket 210, and always maintain the electrical connection between the plug-in terminal 310 and the harness socket 210, so that the plug-in terminal 310 and the harness socket 210 have strong electrical stability and anti-interference.

[0040] During use: When the actuator is assembled, when the rear cover 400 is installed on the front shell 500, the plug-in terminal 310 is docked with the elastic plug interface 211 of the wiring harness socket 210 to complete the electrical connection, and the motor 600 is connected to the wiring harness socket 210 through the electrical wiring harness 100, which can resist bumps, vibrations and interference, and ensure the stability of the power supply of the motor 600.

[0041] In some embodiments, see 1 to Figure 3 The electrical harness 100 is a loose and flexible electrical harness 100. The electrical harness 100 is specifically a flexible cable. The cable includes two independent wires and an insulating skin. The wires can be connected to the positive and negative electrodes to supply power to the motor 600. The cable is loose and can be bent at will. Under the bumps and vibrations of the car itself, the motor 600 is driven to vibrate. The cable can absorb the vibration of the motor 600, so that the motor 600 can always get a stable power supply and maintain a continuous working and running state.

[0042] In some embodiments, see Figure 4 and Figure 5 The wiring harness socket 210 includes a connecting piece 212 connected to the electrical wiring harness 100, a baffle 213 and a spring 214 arranged on both sides of the connecting piece 212. The baffle 213 is integrally connected to the connecting piece 212 and arranged perpendicular to the connecting piece 212. The baffle 213 and the connecting piece 212 form a U-shaped structure. The spring 214 is arranged between the two baffles 213. The two springs 214 are respectively connected to the two baffles 213. The elastic plug-in port 211 is formed between the two springs 214. The plug-in terminal 310 is inserted into the elastic plug-in port 211. The two springs 214 are squeezed to both sides by the plug-in terminal 310. The spring 214 rebounds and presses against the plug-in terminal 310, realizing a stable electrical connection with the plug-in terminal 310. This makes the plug-in terminal 310 and the wiring harness socket 210 have strong electrical stability and anti-interference.

[0043] As a further implementation, the spring piece 214 is arc-shaped, and the opening directions of the two spring pieces 214 are arranged in opposite directions. The arc portions of the two spring pieces 214 are arranged relatively relatively to form an elastic plug interface 211. The arc portions are relatively smooth, which can reduce the friction between the spring piece 214 and the plug-in terminal 310, which is conducive to inserting the plug-in terminal 310 between the two spring pieces 214.

[0044] In some embodiments, please refer to Figure 4 and Figure 5 The mounting seat 220 includes a seat body 221 and a clamping plate 222 protruding from the seat body 221. The three clamping plates 222 are arranged at intervals to form two gaps for clamping the two wiring harness sockets 210. The connecting piece 212 abuts against the seat body 221 and is arranged between the two clamping plates 222. Two adjacent blocking plates 213 are clamped between the two clamping plates 222. The clamping plates 222 can limit the movement of the wiring harness socket 210 relative to the blocking plate 213.

[0045] As a further embodiment, a positioning hole 212a is provided on the connecting piece 212, and a positioning pin 221a is provided on the seat body 221, and the positioning pin 221a is inserted into the positioning hole 212a. The positioning pin 221a can position and fix the connecting piece 212 as a whole, and limit the freedom of movement of the connecting piece 212. The positioning pin 221a can cooperate with the clamping plate 222 to further limit the movement of the wiring harness socket 210, ensure that the mounting seat 220 and the wiring harness socket 210 maintain relatively accurate and stable positioning, and improve the connection accuracy with the plug terminal 310.

[0046] As a further embodiment, a first mounting hole 212b is provided on the connecting piece 212, a second mounting hole 221b is provided on the seat body 221, the first mounting hole 212b and the second mounting hole 221b are coaxially arranged, and screws pass through the first mounting hole 212b and the second mounting hole 221b to connect with the rear cover 400. The coordinated arrangement of the first mounting hole 212b and the second mounting hole and the screw can further strengthen the connection strength between the mounting seat 220 and the wiring harness socket 210 and enhance the structural stability.

[0047] In some embodiments, see Figure 5 The connecting piece 212 is provided with a restraining portion 212c for fixing the electrical wiring harness 100. The restraining portion 212c is provided with a plurality of fixing plates extending outward. The fixing plates can be bent relative to the electrical wiring harness 100 and fix the electrical wiring harness 100 on the connecting piece 212 to achieve electrical connection between the electrical wiring harness 100 and the connecting piece 212.

[0048] In some embodiments, see Figure 1The plug assembly 300 also includes an electrical board 320, which is specifically a printed circuit board. The electrical board 320 is connected to the front shell 500 by bolts. The plug-in terminal 310 is welded to the electrical board 320 and electrically connected to the electrical board 320. The plug-in terminal 310 can conduct electrical energy from the circuit board to the socket assembly 200 to drive the motor 600 to rotate.

[0049] Workflow: First, the motor 600 is fixedly mounted on the rear cover 400, and the electrical board 320 is mounted in the front shell 500. Then, the harness socket 210 is inserted into the mounting seat 220, the baffle 213 is abutted against the clamping plate 222, the positioning pin 221a is inserted into the positioning hole 212a, and the screw is connected to the rear cover 400 through the first mounting hole 212b and the second mounting hole 221b, and the harness socket 210 and the mounting seat 220 are fixed together on the rear cover 400. Next, the rear cover 400 is mounted on the front shell 500, the plug-in terminal 310 is docked with the elastic plug interface 211 of the harness socket 210 to complete the electrical connection, and the two ends of the electrical harness 100 are electrically connected to the motor 600 and the harness socket 210 respectively.
