[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following is for reference. Figures 1-3 According to an embodiment of the present invention, a support ring device 100 for a steering gear is described. The steering gear may include a housing 200, a rack 201, a steering tie rod 202, and a ball pin 203. The rack 201 passes through the housing 200, and the ball pin 203 connects the steering tie rod 202 and the rack 201. The support ring device 100 is fixed inside the housing 200 and sleeved on the rack 201.

[0022] like Figures 1-3 As shown, the support ring device 100 for a steering gear according to an embodiment of the present invention includes: a device frame 10, which is annular; a support structure 20, which is annular to define a mounting through hole 23 for the adapter (i.e., the rack 201 in the above embodiment) to pass through; the device frame 10 is sleeved on the outside of the support structure 20, and the support structure 20 and the device frame 10 are fixedly connected, wherein the support structure 20 is an elastic structure.

[0023] Among them, by Figure 2 As can be seen, the support ring device 100 includes a device frame 10 and a support structure 20. The device frame 10 can be a circular ring structure, made of high-strength metal material. The device frame 10 provides a basic support framework for the entire support ring device 100. For example, the device frame 10 can be made of steel, iron, or other metal materials, giving it sufficient strength and rigidity so that the support ring device 100 does not deform significantly after impact. The support ring device 100 can be press-fitted into the housing 200, with the device frame 10 and housing 200 having an interference fit, thus fixing the support ring device 100 within the housing 200. The outer surface of the device frame 10 can be precision ground, thereby improving the dimensional accuracy of the device frame 10 and thus improving the assembly accuracy of the support ring device 100.

[0024] The support structure 20 is also a ring structure, which can be a circular ring structure. The support structure 20 defines a mounting through hole 23 for the adapter to pass through. The size of the mounting through hole 23 is precisely designed according to the actual application requirements to meet the assembly requirements of the support structure 20 and the adapter. Figure 2As shown, the support structure 20 can be a plastic part, a rubber part, or a nylon part, but this utility model is not limited to these. The support structure 20 can also be made of other materials, as long as it is an elastic part. This application uses a plastic support structure 20 as an example for illustration. The device skeleton 10 is sleeved on the outside of the support structure 20, and the device skeleton 10 and the support structure 20 are in close contact. As an example, the device skeleton 10 and the support structure 20 can be integrally injection molded, thereby fixing the device skeleton 10 and the support structure 20 together. As another example, the device skeleton 10 and the support structure 20 are snap-fitted together. As another example, the device skeleton 10 and the support structure 20 are bonded together. By fixing the device skeleton 10 and the support structure 20 together, the device skeleton 10 and the support structure 20 can be reliably fixed, which helps to improve the overall structure of the support ring device 100, thereby reducing the risk of separation between the device skeleton 10 and the support structure 20.

[0025] The support structure 20 is an elastic structure, which may be made of a polymer material with good elasticity. When the accessory impacts the support structure 20, the support structure 20 can effectively absorb and buffer the vibration and impact generated by the rack 201, which helps to reduce vehicle noise, thereby improving the vehicle's NVH performance and thus improving the vehicle's driving comfort.

[0026] Therefore, by setting the support structure 20 as an elastic structure, the abnormal noise generated by the impact of the adapter on the support structure 20 can be reduced, which is beneficial to reducing vehicle noise, thereby improving the vehicle's NVH performance and thus improving the vehicle's driving comfort. By setting the device frame 10, which is sleeved on the outside of the support structure 20 and keeps in close contact with the support structure 20, the device frame 10 can keep the support ring device 100 with sufficient strength and rigidity, so that the support ring device 100 meets the requirements of support performance. After the adapter impacts the support structure 20, the support ring device 100 can be made to have no obvious deformation.

[0027] According to one embodiment of the present invention, such as Figure 3 As shown, the outer wall of the support structure 20 has a mounting groove 21, and at least a portion of the device frame 10 is located within the mounting groove 21.

[0028] Among them, by Figure 3As can be seen, the outer wall of the support structure 20 has a mounting groove 21, which can be annular and is arranged around the support structure 20 circumferentially. The shape of the mounting groove 21 matches the shape of the device frame 10, so that at least a portion of the device frame 10 can be securely embedded in the mounting groove 21. For example, a portion of the device frame 10 is embedded in the mounting groove 21, or the entire structure of the device frame 10 is embedded in the mounting groove 21. By placing at least a portion of the device frame 10 within the mounting groove 21, the sidewall of the mounting groove 21 can limit the support structure 20 along the axial direction of the support structure 20, reducing the risk of movement of the support structure 20 relative to the device frame 10. This ensures a firm and reliable assembly of the device frame 10 and the support structure 20, which is beneficial to improving the overall structural stability of the support ring device 100. It should be noted that the axial direction of the support structure 20 is... Figure 3 The X direction in the equation.

[0029] According to one embodiment of the present invention, at least one end of the support structure 20 is formed with a bent flange 24 that bends toward the device frame 10 along the axial direction of the support structure 20, and the bent flange 24 and the device frame 10 are opposite to each other along the axial direction of the support structure 20.

[0030] Along the axial direction of the support structure 20, at least one end of the support structure 20 has a bent flange 24 that bends toward the device frame 10. As an example, one end of the support structure 20 has a bent flange 24 that bends toward the device frame 10. As another example, both ends of the support structure 20 have bent flanges 24 that bend toward the device frame 10. This application describes the support structure 20 with bent flanges 24 at both ends as an example. The support structure 20 has a structural body 25, and the structural body 25 and the bent flanges 24 are connected. The structural body 25 and the bent flanges 24 can be integrally formed. Exemplarily, the structural body 25 and the two bent flanges 24 together define a mounting groove 21, or the outer wall of the structural body 25 has a mounting groove 21. The bent flange 24 can be formed by processes such as stamping and bending. The bent flange 24 and the device frame 10 are arranged opposite each other along the axial direction of the support structure 20. In other words, the orthographic projections of the bent flange 24 and the device frame 10 overlap along the axial direction of the support structure 20. By providing the bent flange 24, when the bent flange 24 is in contact with the device frame 10, the bent flange 24 can limit the device frame 10, reducing the risk of the device frame 10 moving along the axial direction of the support structure 20. Furthermore, as... Figure 1As shown, when the ball pin 203 impacts the support ring device 100 along the axial direction, the ball pin 203 can impact the bent flange 24, causing the ball pin 203 and the bent flange 24 to come into contact. While maintaining the support performance, it can reduce the abnormal noise generated by the ball pin 203 impacting the support ring device 100, which is conducive to further reducing vehicle noise, thereby further improving the vehicle's NVH performance and further enhancing the vehicle's driving comfort.

[0031] According to one embodiment of the present invention, such as Figure 2 As shown, the bent flange 24 is annular and extends circumferentially along the support structure 20.

[0032] The bent flange 24 can be a circular structure, extending circumferentially along the support structure 20. It can also surround the circumferential edge of the structure body 25. By setting the bent flange 24 as a ring structure, the entire circumference of the device frame 10 facing the ball pin 203 is covered by the bent flange 24. When the ball pin 203 impacts the support ring device 100 axially, it ensures that the ball pin 203 impacts the bent flange 24, making contact between them. This further reduces the abnormal noise generated by the ball pin 203 impacting the support ring device 100, which helps to further reduce vehicle noise, thereby improving the vehicle's NVH performance and ultimately enhancing driving comfort.

[0033] According to one embodiment of the present invention, the structural strength of the device frame 10 is greater than the structural strength of the support structure 20.

[0034] As one example, the device frame 10 is made of metal, while the support structure 20 is made of plastic. As another example, the device frame 10 is made of metal, while the support structure 20 is made of rubber. This design makes the structural strength of the device frame 10 significantly greater than that of the support structure 20. This allows the device frame 10 to bear critical loads as the main load-bearing component, reducing the risk of the support ring device 100 being damaged by impact. The support structure 20 focuses on mitigating impact crushing, thereby ensuring the overall stability and reliability of the support ring device 100.

[0035] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the inner wall of the support structure 20 is formed with a relief groove 22, which extends along the axial direction of the support structure 20 to the end edge of the support structure 20.

[0036] The inner wall of the structural body 25 may have a clearance groove 22, which is recessed towards the device frame 10. The clearance groove 22 extends continuously along the axial direction of the support structure 20 to the end edge of the structural body 25, thus penetrating the structural body 25 along the axial direction of the support structure 20. After the rack 201 passes through the support ring device 100, the clearance groove 22 can provide sufficient clearance space for the rack 201, reducing the risk of interference between the rack 201 and the support ring device 100.

[0037] According to one embodiment of the present invention, a positioning groove is formed on the inner sidewall of the device frame 10, and a positioning boss is formed on the outer sidewall of the support structure 20, and the positioning boss is assembled into the positioning groove.

[0038] The device frame 10 has a positioning groove formed on its inner wall facing the structural body 25, and the structural body 25 has a positioning boss formed on its outer wall facing the device frame 10. The shape and size of the positioning groove match the shape and size of the positioning boss. The positioning grooves and positioning bosses are assembled in a one-to-one correspondence, with at least a portion of the positioning boss embedded in the positioning groove. There are multiple positioning grooves and positioning bosses, which are arranged in a parallel, spaced-apart pattern along the circumference of the support ring device 100. By assembling the positioning bosses into the positioning grooves, the device frame 10 and the support structure 20 can be positioned, reducing the risk of relative movement between them and making the assembly of the device frame 10 and the support structure 20 more reliable, thereby further improving the structural stability of the support ring device 100.

[0039] According to one embodiment of the present invention, there are multiple positioning grooves and multiple positioning bosses, and the multiple positioning grooves and multiple positioning bosses correspond one-to-one.

[0040] The positioning groove and positioning boss can be set to multiple, and multiple positioning grooves and multiple positioning bosses are assembled one-to-one. The concave-convex mating structure realizes precise positioning and rapid assembly, ensuring that the device frame 10 and the support structure 20 can be tightly engaged, thereby enhancing the overall stability and reliability of the support ring device 100.

The support ring device 100 is disposed on the steering gear, which is beneficial to improving the NVH performance of the steering gear system.
