Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a vehicle-mounted steel pedal with cushioning and shock absorption function. Background Technology

[0002] Vehicle running boards are an important component for vehicles with high chassis. Their core function is to provide stable support for drivers and passengers getting in and out of the vehicle, reducing the inconvenience caused by the height difference. Currently, most vehicle running boards on the market are made of steel to meet the strength requirements of human stepping. However, traditional steel running boards generally adopt a structure of direct rigid connection between the "board body and bracket", lacking targeted cushioning and shock absorption design.

[0003] In practical use, when people step on the pedals to get in and out of the vehicle, their feet generate an instantaneous impact. Without a cushioning and shock-absorbing structure, this impact is directly transmitted to the vehicle door sill and connecting parts. Over time, this can lead to loosening of the bolts connecting the bracket to the vehicle body, pedal deformation, and a shortened lifespan. Furthermore, while some pedals have simple rubber pads, these only provide slight cushioning and cannot effectively absorb the impact of people of different weights. They also lack a stabilizing and guiding structure, making them prone to shifting when stepped on, posing a safety hazard. Therefore, designing a high-strength, effectively cushioned, and slip-resistant steel vehicle pedal is essential for this purpose. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle-mounted steel pedal with cushioning and shock absorption functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted steel pedal with buffer and shock absorption function, comprising a main support rod, a connecting elbow fixed to one side of the main support rod, a fixed mounting seat fixed to the connecting elbow, and the fixed mounting seat being fixedly connected to the longitudinal beam of the vehicle frame at the door sill by bolts; a sliding connecting seat is sleeved on the main support rod, and a mounting bracket is integrally fixed on the sliding connecting seat; a locking bolt is threaded through the sliding connecting seat, the front end of the locking bolt abutting against the outside of the main support rod; and a pedal body is provided on the mounting bracket. A buffer and shock-absorbing assembly is provided between the pedal body and the mounting bracket. The buffer and shock-absorbing assembly includes a guide hole, a guide post, a buffer spring, and a rubber shock-absorbing pad. The guide post is vertically fixed to the upper surface of the mounting bracket. The bottom of the pedal body is provided with a cylindrical guide hole that matches the guide post. The top end of the guide post is inserted into the guide hole and slides in cooperation with the guide hole. The buffer spring is sleeved on the outside of the guide post. One end of the buffer spring is connected to the bottom of the pedal body, and the other end is connected to the upper surface of the mounting bracket. The rubber shock-absorbing pad is located between the mounting bracket and the pedal body.

[0006] Preferably, the main support rod, connecting elbow, and fixed mounting base are integrated into one unit.

[0007] Preferably, the sliding connecting seat is a sliding structure on the main support rod, and the outer side of the main support rod is symmetrically provided with planar structures. The connection between the sliding connecting seat and the main support rod is adapted to each other, and the sliding connecting seat is fixed at the position of the main support rod by locking bolts.

[0008] Preferably, the lower side of the pedal body is sleeved on the outside of the mounting bracket, and a wear-resistant nylon sleeve is sleeved on the outside of the mounting bracket by an interference fit, with the outer side of the wear-resistant nylon sleeve in contact with the inner side of the lower side of the pedal body.

[0009] Preferably, the upper and lower sides of the rubber shock-absorbing pad abut against the lower side of the pedal body and the upper side of the mounting bracket, respectively, and the rubber shock-absorbing pad has honeycomb-shaped shock-absorbing holes inside.

[0011] Preferably, the upper side of the pedal body is provided with anti-slip texture, which is a cross-shaped stripe, and the anti-slip texture is integrally formed with the pedal body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) In view of the force characteristics of people stepping on the vehicle when getting on and off the vehicle, the shock-absorbing spring and the honeycomb rubber shock-absorbing pad can greatly buffer the impact force of stepping, significantly reduce the intensity of vibration transmitted to the vehicle body, reduce the risk of loosening of the connection parts, and cover the guide column and guide hole with polytetrafluoroethylene coating. The mounting bracket and the main body of the pedal are directly in contact through the wear-resistant nylon sleeve, which effectively reduces noise and improves the comfort of getting on and off the vehicle.

[0014] (2) The main support rod, connecting elbow and fixed mounting base are integrally formed to enhance its load-bearing capacity; the matching structure of the guide column and guide hole, as well as the matching of the mounting base and the pedal body, ensure that the pedal body moves only in the vertical direction when under force, avoids lateral displacement, and improves the stability of stepping.

[0015] (3) The anti-slip texture improves the anti-slip performance of the pedal body in wet and slippery environments. The shape of the main support rod matches the connection of the mounting bracket, effectively ensuring the stability of the mounting bracket and preventing rotation. Multiple safety designs comprehensively protect the safety of personnel during the process of getting on and off the vehicle.

[0016] (4) The position of the mounting bracket on the main support rod can be adjusted according to different vehicle models by tightening the bolts to adapt to the getting on and off positions of different vehicle models and increase its usability. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides a technical solution: a vehicle steel pedal with buffer and shock absorption function, including a main support rod 1, a connecting elbow 2 fixed on one side of the main support rod 1, a fixed mounting seat 3 fixed on the connecting elbow 2, and the fixed mounting seat 3 being fixedly connected to the longitudinal beam of the vehicle frame at the door sill of the vehicle body by bolts.

[0025] Furthermore, the main support rod 1, connecting elbow 2, and fixed mounting base 3 are integrated into one unit to ensure the overall strength of the vehicle-mounted steel pedal installation structure and improve the load-bearing performance of the vehicle-mounted steel pedal.

[0026] A sliding connecting seat 4 is sleeved on the main support rod 1. An installation support 6 is integrally fixed on the sliding connecting seat 4. A locking bolt 5 is threaded through the sliding connecting seat 4. The front end of the locking bolt 5 abuts against the outside of the main support rod 1. A pedal body 7 is provided on the installation support 6. A buffer and shock absorption component is provided between the pedal body 7 and the installation support 6.

[0027] Furthermore, the sliding connecting seat 4 has a sliding structure on the main support rod 1, which can change the position of the mounting bracket 6 on the main support rod 1 to make it suitable for different vehicle models' entry and exit positions. The main support rod 1 has symmetrical planar structures on its outer side, and the connection between the sliding connecting seat 4 and the main support rod 1 is adapted to each other. This allows the mounting bracket 6 to slide back and forth on the main support rod 1 without rotating, ensuring the safety and stability of the mounting bracket 6 under foot pressure. The sliding connecting seat 4 is fixed to the position of the main support rod 1 by the locking bolt 5, which facilitates the adjustment of the mounting bracket 6 and also ensures its positional stability.

[0028] Furthermore, the pedal body 7 is fitted onto the outer side of the mounting bracket 6, allowing the pedal body 7 to move only up and down on the mounting bracket 6. A wear-resistant nylon sleeve is fitted onto the outer side of the mounting bracket 6 through an interference fit. The outer side of the wear-resistant nylon sleeve is in contact with the inner side of the lower side of the pedal body 7, effectively reducing friction noise generated by direct contact between the pedal body 7 and the mounting bracket 6.

[0029] Furthermore, the upper side of the pedal body 7 is provided with anti-slip texture. The anti-slip texture is a cross-shaped stripe and is integrally formed with the pedal body 7, which increases the anti-slip effect of the pedal body 7 and ensures the safety of using the pedal body 7.

[0030] The shock absorption assembly includes a guide hole 8, a guide post 9, a buffer spring 10, and a rubber shock-absorbing pad 11. The guide post 9 is vertically fixed to the upper surface of the mounting bracket 6. The bottom of the pedal body 7 has a cylindrical guide hole 8 that matches the guide post 9. The top of the guide post 9 is inserted into the guide hole 8 and slides in cooperation with it, ensuring that the pedal body 7 moves smoothly in the vertical direction when stepped on, avoiding instability caused by lateral deviation. The buffer spring 10 is sleeved on the outside of the guide post 9. One end of the buffer spring 10 is connected to the bottom of the pedal body 7, and the other end is connected to the upper surface of the mounting bracket 6. Its elastic parameters have been optimized to accommodate the stepping force of people weighing 40-100kg. It can effectively absorb impact force and ensure that the pedal body 7 returns to its original position quickly, preventing the pedal from sinking too much and affecting the smoothness of getting on and off the vehicle. The rubber shock-absorbing pad 11 is located between the mounting bracket 6 and the pedal body 7.

[0031] Furthermore, the upper and lower sides of the rubber damping pad 11 abut against the lower side of the pedal body 7 and the upper side of the mounting bracket 6, respectively, and the rubber damping pad 11 has honeycomb-shaped damping holes inside. Through the dual action of rubber deformation and honeycomb hole compression, the residual vibration not completely eliminated by the buffer spring 10 is further absorbed, while reducing the impact noise between the mounting bracket 6 and the pedal body 7.

[0032] Furthermore, the inner side of the guide hole 8 and the outer side of the guide post 9 are coated with polytetrafluoroethylene (PTFE) using a spraying process. This reduces the coefficient of friction between the guide hole 8 and the guide post 9, effectively reducing noise generated by sliding friction. It is then fixedly connected to the frame longitudinal beam at the vehicle body sill using bolts.

[0033] Working principle: During installation, the mounting bracket 3 is placed against the lower part of the frame longitudinal beam at the door sill of the car body. The bolts in the mounting holes on the mounting bracket 3 pass through the anti-slip washers and are fixed to the longitudinal beam of the car body, thus completing the installation of the main support rod 1.

[0034] Based on the boarding position at the door, adjust the position of the sliding connecting seat 4 on the main support rod 1 left and right to place the pedal body 7 on the mounting bracket 6 in the most suitable boarding and alighting position, and tighten the locking bolt 5 to fix the position of the mounting bracket 6 on the main support rod 1, so that the pedal body 7 is stable and ensures safe boarding and alighting.

[0035] When a person steps on the pedal body 7 to get on or off the vehicle, the pedal body 7 slides downward along the guide post 9, and the buffer spring 10 compresses to absorb most of the impact force. At the same time, the pedal body 7 compresses the rubber shock-absorbing pad 11. The rubber shock-absorbing pad 11, through deformation and compression of the honeycomb shock-absorbing holes, further absorbs residual vibration and impact force, achieving a dual buffering and shock absorption effect. The anti-slip texture prevents the foot from slipping. When the stepping force disappears, the buffer spring 10 drives the pedal body 7 to return to its original position, and the rubber shock-absorbing pad 11 returns to its original shape, ready for the next use.

[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
