Description

Technical Field

[0001] This utility model relates to the field of automotive foot pedal bracket technology, specifically to an elastic return spring fixing device for automotive foot pedal brackets. Background Technology

[0002] In automotive braking systems, the brake pedal bracket return spring plays a crucial role, ensuring the brake pedal quickly returns to its initial position after the driver releases it, guaranteeing normal braking system operation and driver convenience. However, existing return spring fixing devices have several drawbacks. Currently, in the long-term use of automotive brake pedals, the return spring is simply held in place by its end in the pedal bracket's groove. Exposed to vibrations during vehicle operation, changes in the spring's own elastic stress, and the frequent reciprocating motion of the brake pedal, the return spring can easily become loose, displace, detach, bend, or break, posing a significant safety hazard. Therefore, this paper proposes an elastic return spring fixing device for automotive brake pedal brackets to solve these problems. Utility Model Content

[0003] To solve the problems mentioned above, the technical solution adopted by this utility model is: an elastic return spring fixing device for an automobile pedal bracket, comprising: a pedal mounting plate, a limiting seat provided on one side of the pedal mounting plate, a shaft connected to the limiting seat, a limiting ring fixedly connected to the outer side of one end of the shaft, a pedal bracket body movably sleeved on one end of the shaft that fits against the limiting ring, a first abutment block provided on one end of the pedal bracket body near the limiting ring, a return torsion spring sleeved on the other end of the shaft that fits against the limiting ring, a first bending head provided on one end of the return torsion spring, a second bending head provided on the other end of the return torsion spring, a limiting hole provided on the first abutment block, a U-shaped clip inserted into the limiting hole from below, a fixing ring welded to one end of the pedal mounting plate facing the second bending head, a limiting bearing provided on the inner ring of the fixing ring, and a second abutment block welded to one side of the pedal mounting plate that fits against the fixing ring.

[0004] As a preferred technical solution of this utility model, the U-shaped clip has a fixing hole at one end inside the limiting hole, and the U-shaped clip is clamped to the outside of the bending end of the first bending head.

[0005] As a preferred technical solution of this utility model, the first supporting block has a threaded hole on the side facing the limiting hole, and a screw is threaded inside the threaded hole, the screw extending into the threaded hole and into the fixing hole.

[0006] As a preferred embodiment of this utility model, the bending end of the second bending head is fitted inside the limiting bearing of the fixing ring, and one side of the second bending head abuts against the lower part of the second abutting block.

[0007] As a preferred embodiment of this utility model, one side of the second bending head abuts against the bottom of the first abutting block, and the second abutting block has a right-angled triangular structure.

[0008] As a preferred technical solution of this utility model, the pedal mounting plate is welded to a support plate on one side above the pedal bracket body, and a limit bolt is provided on one end of the support plate facing the side of the pedal bracket body.

[0009] This utility model has the following advantages: The main body of the pedal bracket can stably support the first bent head of the reset torsion spring by pressing down the first abutment block, effectively avoiding bending and breakage caused by uneven force on the first bent head. The U-shaped clamp on the first bent head can effectively prevent the first bent head from detaching from the first abutment block and limit and fix it. The second bent head is supported on the second abutment block as a whole, which can ensure that the second bent head will not bend and break. The rotation of the limit bearing can not only reduce the wear of the second bent head during use, but also prevent the second bent head from falling out and shifting. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figures 1-4 This utility model discloses an elastic return spring fixing device for an automobile foot pedal bracket, comprising: a pedal mounting plate 1, a limiting seat 2 provided on one side of the pedal mounting plate 1, a shaft 3 connected to the limiting seat 2, a limiting ring 4 fixedly connected to the outer side of one end of the shaft 3, a pedal bracket body 5 movably sleeved at one end of the shaft 3 that fits against the limiting ring 4, a first abutment block 6 provided at one end of the pedal bracket body 5 near the limiting ring 4, a return torsion spring 7 sleeved at the other end of the shaft 3 that fits against the limiting ring 4, a first bending head 8 provided at one end of the return torsion spring 7, a second bending head 9 provided at the other end of the return torsion spring 7, a limiting hole 10 provided in the first abutment block 6, a U-shaped clip 11 inserted into the limiting hole 10 from bottom to top, a fixing ring 15 welded to one end of the pedal mounting plate 1 facing the second bending head 9, a limiting bearing 16 provided in the inner ring of the fixing ring 15, and a second abutment block 17 welded to one side of the pedal mounting plate 1 that fits against the fixing ring 15.

[0016] Among them, the U-shaped clip 11 has a fixing hole 12 at one end inside the limiting hole 10. The U-shaped clip 11 is clamped to the outside of the bent end of the first bending head 8. The fixing hole 12 matches the U-shaped clip 11. The first abutment block 6 has a threaded hole 13 on the side facing the limiting hole 10. A screw 14 is threaded into the threaded hole 13. The screw 14 extends into the threaded hole 13 and into the fixing hole 12. Thus, by passing through the fixing hole 12, the screw 14 can effectively limit the U-shaped clip 11. The bending end of the bending head 9 is fitted inside the limiting bearing 16 of the fixing ring 15. One side of the second bending head 9 abuts against the bottom of the second supporting block 17, and the other side of the second bending head 9 abuts against the bottom of the first supporting block 6. The second supporting block 17 has a right-angled triangular structure. The pedal mounting plate 1 is located on the side above the pedal bracket body 5 and a support plate 18 is welded thereon. One end of the support plate 18 is provided with a limiting bolt 19 facing the side of the pedal bracket body 5. The limiting bolt 19 can limit the highest position of the pedal bracket body 5 to return to its original position.

[0017] Specifically, when this utility model is in use, when the pedal support body 5 rotates around the shaft 3, the first abutment block 6 on the pedal support body 5 presses down on the first bent head 8 of the reset torsion spring 7, and the first bent head 8 is subjected to force at the bottom of the first abutment block 6, which can stably support the first bent head 8 and prevent the first bent head 8 from bending and breaking due to uneven force. The first bent head 8 is also clamped on the first bent head 8 by the U-shaped clip 11, which can effectively prevent the first bent head 8 from detaching from the first abutment block 6 and perform limiting fixation. When the reset torsion spring 7 is subjected to external force, the second bent head 9 is similarly supported on the second abutment block 17, which can ensure that the second bent head 9 will not bend and break. The second bent head 9 can rotate through the limiting bearing 16, which not only reduces the wear of the second bent head 9 during use, but also prevents the second bent head 9 from dislodging through the limiting bearing 16, thus achieving the function of limiting.

[0018] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0019] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
