[0002] The brushed controller is the brain of an electric vehicle, enabling all its functions, such as speed regulation, brake power cut-off, undervoltage protection, and internal controls such as overheat protection, overcurrent protection, and phase loss protection. EPS, or electric power steering system, refers to a power steering system that relies on an electric motor to provide auxiliary torque.

[0003] When a vehicle is traveling on bumpy roads, the interface is easily subjected to repeated external impacts due to the continuous vibration of the vehicle body, leading to loosening of the connection. Once the interface becomes loose, signal transmission will be severely interfered with, or even interrupted. This will not only prevent the EPS system from accurately sensing the driver's steering intentions and thus fail to provide timely and precise assistance, but will also seriously affect driving control and comfort, easily leading to sudden power steering failure and greatly increasing driving safety hazards. Therefore, a brushed EPS controller with a fixed interface is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a brushed EPS controller for easy interface fixing, comprising a base 1 and a housing 2. A heat sink 15 is fixedly connected to the top of the housing 2, and a fixing component and a connecting component are installed in the middle of the housing 2. The fixing component includes two fixing blocks 3, which are fixedly connected to the outside of the housing 2. A threaded rod 16 is threadedly connected to the middle of the fixing block 3. A clamp 4 is threadedly connected to the outside of one end of the threaded rod 16, and a handle 6 is fixedly connected to the outside of the other end of the threaded rod 16. Two connecting rods 7 are fixedly connected to the outside of the clamp 4, and a spring 8 is sleeved on the outside of the connecting rod 7. By rotating the handle 6, the threaded rod 16 is rotated, and the clamp 4 moves along the connecting rod 7 towards the connector 17 through threaded transmission, thereby fixing the wire harness interface. The spring 8 is sleeved on the connecting rod 7 and provides elastic preload during clamping, which can automatically compensate for gap changes caused by vibration, wear, or thermal expansion and contraction. A slot 18 is opened in the middle of the fixing block 3, and the connecting rod 7 is slidably connected inside the slot 18. A fixing bolt 5 is provided in the middle of the fixing block 3, and the fixing bolt 5 is threaded to the middle of the housing 2. The fixing block 3 is detachably connected to the housing 2 via the fixing bolt 5, which supports the replacement of clamps 4 of different specifications and is compatible with various vehicle interfaces. The connecting rod 7 slides in the slot 18 of the fixing block 3 to ensure the linear movement of the clamp 4 and improve clamping stability. A connector 17 is fixedly connected to the outside of the housing 2, and the connector 17 is installed between the two fixing blocks 3.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The connecting assembly includes a housing 9, which is fixedly connected to the outside of the housing 2. A locking post 13 is slidably connected to the middle of the housing 9, and a locking groove 11 is provided in the middle of the base 1, which engages with the locking post 13. A pull ring 10 is provided in the middle of the locking post 13, and a second spring 12 is sleeved on the outside of the locking post 13. A limiting block 14 is fixedly connected to the outside of the locking post 13, located in the middle of the housing 9. The limiting block 14 contacts the second spring 12. The locking post 13 engages with the locking groove 11, and after the spring returns, the locking post 13 locks with the locking groove 11, realizing the quick docking of the housing 2 and the base 1. The second spring 12 continuously provides elastic force, making the locking post 13 and the locking groove 11 fit tightly, ensuring a stable connection. The locking post 13 can be manually pulled by the pull ring 10 to overcome the spring force and release the lock, realizing the quick installation of the housing 2 and the base 1, and facilitating disassembly.

[0034] Working principle: Rotating the handle 6 drives the threaded rod 16 to rotate, causing the clamp 4 to move along the connecting rod 7 towards the connector 17, thus clamping the wire harness interface. A spring 8, sleeved on the connecting rod 7, provides cushioning force after the clamp 4 contacts the connector 17. The spring 8 automatically compensates for gap changes caused by vibration, wear, or thermal expansion and contraction, improving clamping stability. The fixing block 3 is detachably connected to the housing 2 via fixing bolts 5, facilitating the replacement of the clamp 4 according to different vehicle interface specifications, thus achieving the device's versatility.

[0035] During installation, pulling the pull ring 10 causes the locking post 13 to compress the second spring 12, aligning the housing 2 with the locking groove 11 for engagement. Then, releasing the second spring 12 allows the spring force to push the locking post 13 tightly into the locking groove 11, achieving quick locking of the housing 2 and the base 1. Assembly can be completed without tools. During disassembly, pulling the pull ring 10 in the middle of the locking post 13 overcomes the spring force of the second spring 12, pulling the locking post 13 out of the locking groove 11, releasing the locking state, and facilitating quick separation of the housing 2 and the base 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
