[0002] In automotive applications, EPB mainly uses electronic control to replace the original mechanical manual operation parts such as parking brake handles and cables. In order to ensure the stability of the EPB system, the motor at the caliper end will have a specific connector to ensure the stability of the connection between the motor and the line; the current EPB motor connectors are all matched with the EPB motor. Due to the different designs of various motor manufacturers, the connector interfaces of the motors are different in shape, and the motor interfaces of different manufacturers are not universal, which is very inconvenient in the functional debugging stage. Therefore, it is necessary to design a new connection method to increase adaptability while abandoning sealing, so as to adapt to the EPB motor interfaces of different manufacturers in the functional debugging stage, thereby improving the debugging efficiency.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figures 1 to 4 The utility model provides a universal EPB motor connector: including an EPB motor, a power supply, an upper clamping plate 2, a lower clamping plate 1, two sets of insulating seats 8 and two sets of power lines 7, the upper clamping plate 2 and the lower clamping plate 1 are opposite to each other, and the inner wall of the upper clamping plate 2 is provided with two sets of guide holes 13 that penetrate vertically, and the two sets of guide holes 13 are distributed front and back;

[0025] like Figure 1 , Figure 3As shown, in order to keep the upper clamping plate 2 and the lower clamping plate 1 in a smooth movement when clamping and releasing, a guide structure for guiding the lower clamping plate 1 and the upper clamping plate 2 when they move relative to each other is provided between the two groups of guide holes 13 and the lower clamping plate 1, and the guide structure includes two groups of guide blocks 3, the two groups of guide blocks 3 are fixedly connected to the upper wall of the lower clamping plate 1 and are respectively opposite to the two groups of guide holes 13 in the upper and lower directions, and the outer walls of the two groups of guide blocks 3 are respectively slidably connected to the inner walls of the two groups of guide holes 13, and through the sliding connection between the guide blocks 3 and the guide holes 13, the upper clamping plate 2 can move back and forth and relative to the lower clamping plate 1, thereby forming a release and clamping action;

[0026] like Figure 1 As shown, in order to drive the upper clamping plate 2 and the lower clamping plate 1 to move in opposite directions and relative to each other, a clamping driving structure for driving the upper clamping plate 2 and the lower clamping plate 1 to move along the guide structure is provided between the upper clamping plate 2 and the lower clamping plate 1. The clamping driving structure is a pen-type linear actuator 5. The pen-type linear actuator 5 is fixedly connected to the upper wall of the upper clamping plate 2 and is located between the two groups of guide holes 13. The extension shaft of the pen-type linear actuator 5 passes through the upper clamping plate 2 and extends to between the upper clamping plate 2 and the lower clamping plate 1. The end of the extension shaft of the pen-type linear actuator 5 is fixedly connected to the upper wall of the lower clamping plate 1. The pen-type linear actuator 5 can be a common cylinder or electric telescopic rod on the market. Through the extension and retraction of the extension shaft of the pen-type linear actuator 5, the upper clamping plate 2 and the lower clamping plate 1 are driven to move in opposite directions and relative to each other.

[0027] like Figure 1 As shown, in order to enable the upper clamping plate 2 and the lower clamping plate 1 to separate more quickly when the pen-type linear actuator 5 drives the upper clamping plate 2 and the lower clamping plate 1 to move away from each other, a spring 4 for assisting the upper clamping plate 2 to separate from the lower clamping plate 1 is provided between the upper clamping plate 2 and the lower clamping plate 1 and between the two groups of guide holes 13, and the elastic force of the spring 4 assists the upper clamping plate 2 to separate from the lower clamping plate 1;

[0028] An anti-skid structure for preventing slipping after clamping is also provided between the upper clamping plate 2 and the lower clamping plate 1. The anti-skid structure includes two sets of anti-skid pads 6. The two sets of anti-skid pads 6 are respectively fixedly connected between the upper clamping plate 2 and the lower clamping plate 1 and are respectively close to the front ends of the upper clamping plate 2 and the lower clamping plate 1. When the upper clamping plate 2, the lower clamping plate 1 and the edge of the EPB motor socket are clamped and fixed, the friction force is increased by the two sets of anti-skid pads 6 to avoid slipping.

[0029] like Figure 4As shown, in order to fix the power cord 7 to the lower clamping plate 1, one end of the two groups of power cords 7 is fixedly connected to the two groups of insulating seats 8 respectively, and the ends of the two groups of power cords 7 away from the insulating seats 8 are electrically connected to the power supply, and the outer walls of the two groups of power cords 7 between the insulating seats 8 and the power supply are connected to the lower wall of the lower clamping plate 1 through a pipeline fixing structure, and the pipeline fixing structure includes two groups of fixing tubes 14, and the two groups of fixing tubes 14 are distributed left and right and fixedly connected to the lower wall of the lower clamping plate 1 in sequence, and the outer walls of the two groups of power cords 7 between the power supply and the insulating seat 8 are slidingly connected to the inner side walls of the two groups of fixing tubes 14 respectively, and the power cord 7 is locked with the fixing tube 14 by a locking screw 15, and the end of the power cord 7 away from the insulating seat 8 penetrates the inner wall of the fixing tube 14 and then extends out, and then is electrically connected to the power supply, because the upper clamping plate 2, the lower clamping plate 1 and the EPB motor socket are clamped and fixed together, so that the power cord 7 between the fixing tube 14 and the PIN pin of the EPB motor remains fixed and will not be pulled when the power end moves, thereby avoiding the terminal structure and the PIN pin from being separated;

[0030] like Figure 1 , Figure 2 As shown, in order to form an electrical connection, an end of the insulating seat 8 away from the power cord 7 is fixedly connected to an insulating shell 9, and an inner wall of the insulating shell 9 is provided with a terminal structure for electrically connecting to the EPB motor PIN pin. The terminal structure is electrically connected to the power cord 7. The terminal structure includes a rubber layer 10 and two groups of conductive blocks 11. The rubber layer 10 is arranged on the inner wall of the insulating shell 9. The two groups of conductive blocks 11 are distributed up and down and are arranged in sequence on the inner wall of the rubber layer 10. The two groups of conductive blocks 11 are squeezed by the rubber layer 10 to form abutment. A connecting groove 12 is provided between the opposite sides of the two groups of conductive blocks 11. The two groups of connecting grooves 12 jointly form a plugging hole for plugging with the EPB motor PIN pin. The two groups of conductive blocks 11 are both electrically connected to the power cord 7. The terminal structure is plugged toward the outer wall of the EPB motor PIN pin. The EPB motor PIN pin squeezes the two groups of conductive blocks 11 into the plugging hole and is kept clamped by the squeezing of the rubber layer 10.

[0031] Working principle: Plug the terminal structure toward the outer wall of the EPB motor PIN pin, the EPB motor PIN pin squeezes the two groups of conductive blocks 11 into the plug-in hole, and is kept clamped by the extrusion of the rubber layer 10. The extension and retraction of the extension shaft of the pen-type linear actuator 5 drives the upper clamping plate 2 and the lower clamping plate 1 to move back and forth and relative to each other. The two groups of anti-slip pads 6 can increase the friction force to avoid slipping. The two groups of guide blocks 3 keep the upper clamping plate 2 and the lower clamping plate 1 clamped and released for smooth movement. The elastic force of the spring 4 can assist the upper clamping plate 2 to separate from the lower clamping plate 1. Since the upper clamping plate 2, the lower clamping plate 1 and the EPB motor socket are clamped and fixed together, the power line 7 between the fixed tube 14 and the EPB motor PIN pin remains fixed and will not be pulled when the power end moves, thereby avoiding the terminal structure and the PIN pin from separating.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
