[0001] The utility model relates to the technical field of wire-controlled brake systems, in particular to a wheel side connector structure of an electric control brake. Background Art

[0002] In recent years, the commercial application and development of EMB brakes has matured. Because these brake actuators are located entirely within the vehicle's wheel, the compactness of existing wheel-side structures has limited the design and layout of EMB brakes' wheel-side electronic control cable wiring. This has become increasingly important for EMB suppliers during product development and design, facilitating their successful industrialization.

[0003] Patent CN116767160A schematic diagram discloses a wiring arrangement for the electronic control cable of an EMB brake, but this arrangement poses a risk of water ingress into the wheel-side brake connector, making it unsuitable for industrial application. Patent CN221097269U discloses a wiring arrangement for the electronic control cable of an EMB brake, but this arrangement requires the entire vehicle's cables to be wound around the inside of the rim, leading to the risk of interference between the wiring harness arrangement and the rim when arranged in some smaller rims.

[0023] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0024] like Figure 1-Figure 3 As shown, a wheel side connector structure of an electronically controlled brake includes a caliper body assembly 1 and an MGU assembly 2. The caliper body assembly 1 includes a cylinder hole 11. The MGU assembly 2 is mounted on the caliper body assembly 1 with the cylinder hole 11 as a reference. The MGU assembly 2 includes a motor 21, a housing 22, and a plug-in portion 23. The motor 21 and the plug-in portion 23 are both mounted on the housing 22. The motor 21 and the plug-in portion 23 are respectively located at both ends of the housing 22 and on both sides of the cylinder hole 11. The motor 21 and the plug-in portion 23 are respectively located at both ends of the housing 22, making the entire structure more convenient. It is more compact, which is conducive to saving space, and the motor 21 and the connector 23 are located on both sides of the cylinder hole 11, avoiding crossing or overlapping in the wiring harness arrangement, further improving space utilization, and making the direction of the wiring harness clearer, which is conducive to reducing line confusion and the occurrence of faults. At the same time, it also reduces the impact of electromagnetic interference and mechanical vibration on the connector 23, improves the stability and reliability of the system, and after the brake is installed, compared with the traditional outlet structure placed in the axial direction of the cylinder hole, it has better adaptability and application effect in different suspension structures.

[0025] To further explain, Figure 2 As shown, the motor 21 is located at one end of the shell 22, and the plug-in portion 23 is located at the other end opposite to the end. When the motor 21 is located on the left side of the shell 22, the plug-in portion 23 is located at the upper right side opposite thereto. When the motor 21 is located on the right side of the shell 22, the plug-in portion 23 is located at the upper left side opposite thereto. Preferably, the motor 21 is located on the left side of the shell 22, and the plug-in portion 23 is located on the right side of the shell 22, which is conducive to the arrangement of electronic components on the PCB board, so as to reduce the risk of non-compliance with design requirements during EMC testing. At the same time, the motor 21 and the plug-in portion 23 are respectively located at the upper left and right sides of the shell 23, which can maximize the use of the space in the shell, provide a more spacious arrangement channel for the wiring harness, and reduce the squeezing and bending of the wiring harness in a small space.

[0026] Among them, the plug-in part 23 is an integral injection molding, which is conducive to the integrated structural design of the MGU assembly 2. At the same time, it can effectively reduce production costs, improve the waterproof sealing performance of the product, and is more conducive to industrial production and improve product quality stability. The plug-in part 23 is made of PBT-GF30 or plastic material, which has the characteristics of high strength and light weight, and can ensure the stability and durability of the connection.

[0027] In this embodiment, Figure 2As shown, the connector 23 includes a first connector 231 and a second connector 232, and the first connector 231 and the second connector 232 are located on the same side of the housing 22, which helps to optimize the layout of the connector in a limited space and ensure that the relative positions and spacings between the components meet the design requirements. There is a gap between the first connector 231 and the second connector 232, so that the wiring harness can be more flexible in selecting paths when arranging, avoiding crossing and congestion, thereby optimizing the spatial layout, and also providing sufficient space for the wiring harness, making the wiring process smoother, reducing the wiring difficulty caused by space limitations, and reducing friction and interference between wiring harnesses, reducing the risk of system failures caused by wiring harness problems, improving system reliability, and facilitating air circulation, reducing heat accumulation around the wiring harness, thereby enhancing heat dissipation performance.

[0028] Furthermore, the plug-in portion 23 is away from the motor 21 and is located on the outside of the end of the shell 22, so that there is a gap between the plug-in portion 23 and the shell 22, so that the plug-in portion 23 can make full use of the space outside the shell 22 and avoid competing for space with internal components such as the motor 21, thereby providing a more spacious and flexible layout space for the wiring harness. Setting the plug-in portion 23 away from the motor 21 can reduce the impact of vibration, heat and electromagnetic interference generated by the operation of the motor 21 on the wiring harness, ensuring the stability and reliability of the wiring harness. At the same time, the gap between the plug-in portion 23 and the shell 22 can serve as a protective layer for the wiring harness, reducing the risk of the wiring harness being subjected to external impact and extrusion, and improving the service life of the wiring harness.

[0029] In order to avoid the problem of insufficient clearance with various moving parts, there is a height difference between the plug-in part 23 and the surface of the shell 22, so that the plug-in part 23 is located at the highest point of the caliper body assembly 1. The plug-in part 23 is located at the highest point of the caliper body assembly 1, which can ensure that the wiring harness will not interfere with the caliper body assembly 1 or other components during layout, avoiding wire harness wear caused by friction or extrusion, and providing a more flexible and spacious routing path for the wire harness, so that the wire harness can be more smoothly connected to the plug-in part 23, reducing the wiring difficulty caused by space limitations, and allowing the wire harness to be arranged more compactly around the caliper body assembly 1.

[0030] Furthermore, the first connector 231 and the second connector 232 are symmetrical along the center of the shell 22, and the projection of the cylinder hole 11 on the shell 22 is close to the long side of the shell 22, which can more effectively utilize the wheel side space, avoid interference between the wiring harness and other components, and help reduce the bending and twisting of the wiring harness, thereby reducing the stress on the wiring harness during assembly and use. The relative positional relationship between the cylinder hole 11 and the connector provides a relatively stable support point for the wiring harness, reducing the risk of movement and damage of the wiring harness under vibration and impact; the first connector 231 and the second connector 232 are arranged with the same power line and signal line. When the wiring harness on one of the connectors fails, the wiring harness on the other connector can achieve effective safety backup.

[0031] Preferably, the first connector 231 and the second connector 232 are slot-type. The design of slot-type connectors is usually more compact, which can more effectively utilize the limited space on the wheel edge, help reduce the bending and twisting of the wiring harness, and reduce the stress on the wiring harness during assembly and use, thereby improving the stability and durability of the wiring harness.
