Description

Technical Field

[0001] This application relates to the technical field of shock-absorbing pedals, and particularly to a shock-absorbing pedal structure for industrial vehicles. Background Art

[0002] In the prior art, the shock-absorbing pedal structures of industrial vehicles mostly adopt single or simple shock-absorbing designs, such as achieving shock-absorbing effects only through springs or rubber pads. These design solutions can relieve the vibration impact on operators to a certain extent during vehicle operation, but there are obvious drawbacks. First, since the shock-absorbing effect is greatly affected by the driver's weight, drivers of different weights experience significantly different shock-absorbing effects under the same conditions, resulting in uneven overall comfort. Second, the reliability of the existing shock-absorbing structures is poor, and they are prone to wear and failure after long-term use, requiring frequent replacement, which increases the maintenance cost and difficulty. Finally, some shock-absorbing devices are complex to install, not convenient for quick installation and disassembly, and affect the maintenance efficiency and flexibility of the vehicle.

Detailed Embodiment

[0017] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0018] An embodiment of the present application discloses a shock-absorbing pedal structure for an industrial vehicle. Refer to Figure 1, including a pedal base 1. A set of activity areas 3 are provided inside the pedal base 1. A support frame 2 is fixed outside the activity area 3. One end of the support frame 2 is internally connected with a first support rod 4. A set of support pressure rods 9 are rotatably arranged on the first support rod 4. The support pressure rods 9 can move within the activity area 3 and allow swinging within a certain range to adapt to different operating postures. A pedal 5 is installed on the outer wall of the support pressure rods 9. The pedal 5 is made of high-strength and wear-resistant materials to ensure load-bearing capacity and service life. A pedal pad 6 is connected to the surface of the pedal 5. First-stage shock-absorbing structures 12 are provided on both sides of the back wall of the pedal 5. The inner parts of the two support frames 2 away from one end of the first support rod 4 are connected with a second support rod 8. The top ends of the inner walls of the two support pressure rods 9 are both connected with a second connecting shaft 11. The two ends of the first-stage shock-absorbing structure 12 are respectively connected with the second support rod 8 and the second connecting shaft 11. The first-stage shock-absorbing structure 12 uses high-strength springs or elastic elements as a preliminary shock-absorbing layer to directly absorb most of the low-frequency vibrations.

[0019] As Figure 2 shown, a second-stage shock-absorbing structure 13 is provided between the two first-stage shock-absorbing structures 12. The second-stage shock-absorbing structure 13 is a more precise shock-absorbing device, such as a gas spring or a hydraulic shock absorber, to further attenuate the remaining vibration energy and improve the shock-absorbing effect. A first connecting shaft 10 is fixed between the two support pressure rods 9. A support seat 7 is fixed in the middle of the back wall of the pedal base 1. The two ends of the second-stage shock-absorbing structure 13 are respectively connected with the first connecting shaft 10 and the support seat 7 to support the back wall of the pedal 5.

[0020] Combined with Figure 3 shown, a third-stage shock-absorbing structure 14 is provided at the bottom of the first-stage shock-absorbing structure 12. A positioning member 15 is connected to the inner wall of the activity area 3 by screws. The bottom ends of the inner walls of the two support pressure rods 9 are both installed with a third connecting shaft 16. The two ends of the third-stage shock-absorbing structure 14 are respectively connected with the positioning member 15 and the third connecting shaft 16. The third-stage shock-absorbing structure 14 uses a damping mechanism or energy-absorbing material to ensure a stable shock-absorbing effect even under high-intensity vibrations. The overall structure is simple and ingenious, forming an integral structure, thus simplifying the installation process and improving the installation efficiency.

[0021] The implementation principle of a shock-absorbing pedal structure for an industrial vehicle in an embodiment of the present application is as follows: By fixing the pedal seat 1, the overall positioning can be formed, providing a stable installation foundation for the pedal 5. It is connected to the vehicle chassis through bolts or other fasteners. During use, the operator steps on the pedal 5. At this time, the support pressure rod 9 is stressed to squeeze the primary shock-absorbing structure 12 and the secondary shock-absorbing structure 13. The primary shock-absorbing structure 12 serves as a preliminary shock-absorbing layer, supporting between the connecting shaft II 11 and the support rod II 8, directly absorbing most of the low-frequency vibrations. The secondary shock-absorbing structure 13 further absorbs and disperses the vibration energy, improving the shock-absorbing effect. At this time, the support pressure rod 9 is stressed to adapt to different operating postures and rotates and adapts outside the support rod I 4 accordingly. At the same time, the tertiary shock-absorbing structure 14 supports the bottom end of the support pressure rod 9 by the positioning member 15 and the connecting shaft III 16, further attenuating the remaining vibration energy. By adopting the primary, secondary, and tertiary shock-absorbing structures, multi-level attenuation of the vibration energy is achieved, significantly improving the shock-absorbing effect, enabling operators of different weights to obtain a good comfort experience.
