For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Reference Figures 1 to 6 , shows a structural schematic diagram of a spring retaining structure described in an embodiment of the present application, which may specifically include: the spring retaining structure 42 includes a spring retaining body 10 and a clamping portion, the clamping portion includes an elastic return segment 30 and a first connecting segment, the elastic return segment 30 is connected to the spring retaining body 10 through the first connecting segment, the first connecting segment includes at least a first arc-shaped sub-segment 31, and the center of the circle where the first arc-shaped sub-segment 31 is located is located on the side of the first arc-shaped sub-segment 31 close to the elastic return segment 30.

[0038] In the embodiment of the present application, the clamp body 10 can be used to fix the clamp structure 42, so that the clamp structure 42 has good stability. The connection between the elastic return segment 30 and the clamp body 10 is achieved through the first connecting segment, so that the two have good connection reliability, and the center of the circle where the first arc sub-segment 31 is located is located on the side of the first arc sub-segment 31 close to the elastic return segment 30, so that there is a relatively stable stress transfer effect between the first arc sub-segment 31 and the elastic return segment 30, so that the clamping part has a good elastic return force through the elastic return segment 30 and the first arc sub-segment 31.

[0039] When the vehicle is braked, the brake pad is clamped to the clamping part under pressure, so that the brake pad abuts against the brake disc to achieve braking effect; when the vehicle completes braking, the pressure on the brake pad is released, and the elastic return segment 30 and the first arc-shaped sub-segment 31 of the first connecting segment provide a rebound force for the clamping part. Specifically, the first arc-shaped sub-segment 31 and the elastic return segment 30 can disperse the return force into component forces transmitted in multiple directions through the arc-shaped curved surface structure, so that the clamping part is not easy to deform and has a relatively stable return effect. It avoids the bending part 163 of the connecting clamping plate from being easily deformed due to the relatively concentrated stress when the clamping part is separated from the brake pad, and avoids the poor return stability of the clamping part, which makes the retaining spring structure 42 and the brake pad easy to get stuck, thereby improving the driving stability of the vehicle.

[0040] Specifically, in the embodiments of the present application, Figure 3 and Figure 4 As shown, the elastic return segment 30 is an arc segment with a larger curvature, and the position and bending direction of the first arc sub-segment 31, as well as the positions and bending directions of the following other arc segments such as the second arc sub-segment 32, the third arc sub-segment 33, the fourth arc sub-segment 34 and the fifth arc sub-segment 35 can be defined based on the center of the elastic return segment 30. For example, the center of the elastic return segment 30 can be the midpoint of the line connecting the two ends of the elastic return segment 30, and the center of the circle where the first arc sub-segment 31 is located is located on the side of the first arc sub-segment 31 close to the elastic return segment 30, that is, the bending direction of the first arc sub-segment 31 or the direction of the opening 121 is toward the elastic return segment 30.

[0041] For example, in the embodiment of the present application, the retaining spring body 10 can be a rectangular structure with an opening, or a U-shaped retaining plate, or a C-shaped structure, etc., and can be set according to the specific structure of its installation position. The embodiment of the present application does not limit the specific shape structure of the retaining spring body 10.

[0042] In the embodiment of the present application, for example, the number of elastic return segments 30 can be 2, and the two elastic return segments 30 are nested with each other and connected end to end. In addition, the number of elastic return segments 30 can also be 3 or 4, etc., and can be set according to actual needs based on the size of the brake disc, stress requirements, etc. The embodiment of the present application does not limit the specific number of elastic return segments 30.

[0043] Optionally, in the embodiment of the present application, the first connecting section further includes a second arc-shaped sub-segment 32, and the second arc-shaped sub-segment 32 is connected between the first arc-shaped sub-segment 31 and the clamp body 10. In this way, the first connecting section can realize stress transmission with the elastic return section 30 through the first arc-shaped sub-segment 31 and the second arc-shaped sub-segment 32, and under the action of multiple curved surface structures of the first arc-shaped sub-segment 31 and the second arc-shaped sub-segment 32, the return force can be further dispersed in multiple different directions, thereby improving the improvement effect on stress concentration, making the clamping part less likely to deform and stable in return. Therefore, the clamping part can realize more stable and reliable stress transmission, further improving the stability of force transmission.

[0044] In the embodiment of the present application, optionally, the center of the circle where the second arc sub-segment 32 is located is located on the side of the second arc sub-segment 32 away from the elastic return segment 30. That is, the bending direction or the opening 121 direction of the second arc sub-segment 32 is arranged away from the elastic return segment 30. In this way, the transmission of the return force between the second arc sub-segment 32 and the first arc sub-segment 31 and the clamping spring body 10 can achieve a relatively smooth transition, reduce the risk of stress concentration, and improve the return effect of the elastic return segment 30 on the brake pad.

[0045] Optionally, in the embodiment of the present application, the first connecting section further includes a third arc-shaped sub-segment 33, and the third arc-shaped sub-segment 33 is connected between the first arc-shaped sub-segment 31 and the elastic return segment 30. In this way, the first connecting section can realize stress transmission with the elastic return segment 30 through the first arc-shaped sub-segment 31 and the third arc-shaped sub-segment 33, and under the action of multiple curved surface structures of the first arc-shaped sub-segment 31 and the third arc-shaped sub-segment 33, the return force can be further dispersed in multiple different directions, thereby improving the improvement effect on stress concentration, making the clamping portion less likely to deform and stable in return. Therefore, the clamping portion can realize more stable and reliable stress transmission, further improving the stability of force transmission.

[0046] In the embodiment of the present application, optionally, the center of the circle where the third arc sub-segment 33 is located is located on the side of the third arc sub-segment 33 away from the elastic return segment 30. That is, the bending direction or the opening 121 direction of the third arc sub-segment 33 is arranged away from the elastic return segment 30. In this way, the transmission of the return force between the third arc sub-segment 33 and the first arc sub-segment 31 and the elastic return segment 30 can achieve a relatively smooth transition, reduce the risk of stress concentration, and further improve the return effect of the elastic return segment 30 on the brake pad.

[0047] Optionally, in the embodiment of the present application, the clamping portion includes a limiting section 20, the limiting section 20 is connected to the elastic return section 30, and the limiting section 20 is used to clamp the brake pad. In this way, the limiting section 20 can achieve a relatively stable limiting effect on the brake pad, preventing the brake pad from shaking and deflecting easily.

[0048] For example, in the embodiment of the present application, the limiting section 20 may include a bonding plate 21 and a hook 22, wherein the bonding plate 21 is connected to the elastic return section 30, and the hook 22 is connected to one end of the bonding plate 21 away from the elastic return section 30. Specifically, when the vehicle is braked, the brake pad is bonded to the bonding plate 21, and the edge of the brake pad abuts against the hook 22, so that the limiting section 20 can achieve a relatively stable and reliable clamping effect on the brake pad.

[0049] In some optional embodiments of the present application, a gap is provided between the bonding plate 21 and the circlip body 10, specifically, the above-mentioned gap is provided between the bonding plate 21 and the third connecting surface 13 of the circlip body 10. When the vehicle is braked, the brake pad abuts against the circlip structure 42, and the gap can make the brake pad and the bracket 41 of the brake caliper have a better tangential matching effect, clamp the brake pad and prevent abnormal noise, and avoid the brake pad and brake disc from producing abnormal noise due to the excessive tangential gap between the brake pad and the bracket 41 of the brake caliper.

In this way, the elastic return section 30 can provide a rebound force for the clamping portion together with the first arc-shaped sub-segment 31 of the first connecting section and the fourth arc-shaped sub-segment 34 of the second connecting section. The first arc-shaped sub-segment 31 and the fourth arc-shaped sub-segment 34 can jointly achieve stress transmission with the elastic return section 30, and under the action of multiple curved surface structures of the first arc-shaped sub-segment 31 and the fourth arc-shaped sub-segment 34, the return force can be further dispersed in multiple different directions, thereby improving the improvement effect on stress concentration, making the clamping portion less likely to deform and stable in return. Thus, the clamping portion can achieve more stable and reliable stress transmission, further improving the force transmission stability and return stability.

[0051] In the embodiment of the present application, optionally, the center of the circle where the fourth arc sub-segment 34 is located is located on the side of the fourth arc sub-segment 34 close to the elastic return segment 30. That is, the bending direction or the opening 121 direction of the fourth arc sub-segment 34 is arranged toward the elastic return segment 30. In this way, the transmission of the return force between the fourth arc sub-segment 34 and the limiting segment 20 and the elastic return segment 30 can achieve a relatively smooth transition, reduce the risk of stress concentration, and further improve the return effect of the elastic return segment 30 on the brake pad.

[0052] Optionally, in the embodiment of the present application, the second connecting section further includes a fifth arc-shaped sub-segment 35, and the fifth arc-shaped sub-segment 35 is connected between the fourth arc-shaped sub-segment 34 and the limiting section 20.

The first arc-shaped sub-segment 31, the fourth arc-shaped sub-segment 34 and the fifth arc-shaped sub-segment 35 can jointly realize stress transmission with the elastic return section 30, and under the action of multiple curved surface structures of the first arc-shaped sub-segment 31, the fourth arc-shaped sub-segment 34 and the fifth arc-shaped sub-segment 35, the return force can be further dispersed in multiple different directions, thereby improving the improvement effect on stress concentration, making the clamping portion less likely to deform and stable in return. Thus, the clamping portion can realize more stable and reliable stress transmission, further improving the force transmission stability and return stability.

[0053] In the embodiment of the present application, optionally, the center of the circle where the fifth arc sub-segment 35 is located is located on the side of the fifth arc sub-segment 35 away from the elastic return segment 30. That is, the bending direction or the opening 121 direction of the fifth arc sub-segment 35 is arranged away from the elastic return segment 30. In this way, the transmission of the return force between the fifth arc sub-segment 35 and the fourth arc sub-segment 34 and the limiting segment 20 can achieve a relatively smooth transition, reduce the risk of stress concentration, and further improve the return effect of the elastic return segment 30 on the brake pad.

[0054] Optionally, in the embodiment of the present application, the second connecting segment further includes a straight segment 36, and the straight segment 36 is connected between the fourth arcuate sub-segment 34 and the fifth arcuate sub-segment 35. In this way, the fourth arcuate sub-segment 34 and the fifth arcuate sub-segment 35 are more reliably connected through the straight segment 36, so that the fourth arcuate sub-segment 34 is transitionally connected to the fifth arcuate sub-segment 35 along the straight direction of the straight segment 36, the structure is simple and easy to process, and the transmission of the return force has good stability.

[0069] In an embodiment of the present application, the retaining spring structure includes a retaining spring body and a clamping portion, the clamping portion includes an elastic return segment and a first connecting segment, the elastic return segment is connected to the retaining spring body through the first connecting segment, the first connecting segment includes at least a first arcuate sub-segment, the center of the circle where the first arcuate sub-segment is located on the side of the first arcuate sub-segment close to the elastic return segment. Specifically, the retaining spring body can be used to fix the retaining spring structure, so that the retaining spring structure has better stability. The connection between the elastic return segment and the retaining spring body is achieved through the first connecting segment, so that the two have better connection reliability, and the center of the circle where the first arcuate sub-segment is located on the side of the first arcuate sub-segment close to the elastic return segment, so that there is a relatively smooth stress transfer effect between the first arcuate sub-segment and the elastic return segment, so that the clamping portion has a better elastic return force through the elastic return segment and the first arcuate sub-segment. After the vehicle has finished braking and the clamping part is separated from the brake pad, the first arc-shaped sub-segment and the elastic return segment can disperse the return force into component forces transmitted in multiple directions through the arc-shaped curved surface structure, so that the clamping part is not easy to deform and has a relatively stable return effect. This avoids the bending part of the connecting clamping plate from being easily deformed due to the relatively concentrated stress when the clamping part is separated from the brake pad, avoids the clamping part from being easily stuck between the clamping spring structure and the brake pad due to the poor return stability of the clamping part, and improves the driving stability of the vehicle.
