Description

Technical Field

[0001] This utility model belongs to the field of engineering vehicle technology, and in particular relates to a shock absorption device for the foot pedal of a transport vehicle. Background Technology

[0002] In modern industrial production, logistics and warehousing, high-speed pallet trucks or other fixed manned platforms (such as forklifts and electric pallet trucks) are essential equipment. Drivers or operators need to stand on the foot pedals of the pallet truck for long periods of time to operate it. Therefore, the comfort of the foot pedals, especially their shock absorption performance, is directly related to the operator's fatigue and working experience.

[0003] Currently, most pallet truck foot pedals on the market have a very simple structural design. To reduce costs, most pallet truck foot pedals completely omit dedicated shock absorption structures. These types of pedals almost directly transmit the impact from the road surface and the vibration of the vehicle body to the driver, with negligible shock absorption. Drivers will experience severe discomfort when driving on bumpy roads or at high speeds, easily leading to fatigue and potentially adverse health effects in the long run. They also reduce the stability and precision of operation.

[0004] While some pallet trucks on the market do have shock-absorbing mechanisms in their foot pedals, these mechanisms often employ floating mechanisms. These solutions typically involve multiple linkages, springs, hydraulic or pneumatic damping elements, resulting in a complex structure and numerous parts. This not only significantly increases manufacturing costs but also makes installation, debugging, and subsequent maintenance and disassembly extremely inconvenient. For space-constrained and cost-sensitive pallet trucks, such overly complex shock-absorbing structures are poorly suited.

[0005] In summary, existing pallet truck foot pedals struggle to achieve a good balance between shock absorption and structural complexity and cost. Therefore, there is a need in this field for a novel foot pedal shock absorption device that can simultaneously provide good shock absorption, has a simple and compact structure, is inexpensive, and is easy to install and maintain. Utility Model Content

[0006] This utility model provides a shock-absorbing device for the foot pedal of a transport vehicle, which has the advantages of good shock absorption effect, simple structure and low cost.

[0007] Other objects and advantages of this utility model can be further understood from the technical features disclosed herein.

[0008] To achieve one or more of the above objectives or other objectives, the present invention provides a shock-absorbing device for a transport vehicle foot pedal, comprising a pedal base connected to the vehicle body of the transport vehicle, a pedal body placed on the pedal base; a plurality of shock-absorbing rubber seats correspondingly provided on the pedal body and the pedal base; a plurality of shock-absorbing rubbers provided between the pedal body and the pedal base, the two ends of the shock-absorbing rubbers being engaged in the shock-absorbing rubber seats.

[0009] The pedal body is provided with a plurality of positioning pins, and the pedal base is provided with pin holes corresponding to the positions of the positioning pins; when the pedal body is installed on the pedal base, the positioning pins are inserted into the pin holes.

[0010] A limit switch is provided on the pedal base; the upper end of the shock-absorbing rubber deforms when squeezed, and the limit switch is not squeezed by the pedal body before the shock-absorbing rubber deforms.

[0011] The height of the limit switch is less than the height of the damping rubber body; the height of the damping rubber under maximum deformation is less than the height of the limit switch.

[0012] The damping adhesive has a tapered vertical cross-section and a circular horizontal cross-section. The diameters of the upper and lower ends of the damping adhesive are larger than the diameter of the middle part, and the upper and lower ends of the damping adhesive transition evenly towards the middle position.

[0013] A pin hole is provided on one side of the limit switch, close to the pedal base, and a positioning pin is provided on the pedal body corresponding to the position of the pin hole.

[0014] The pedal base is provided with a square pedal placement slot; the pedal body is placed in the pedal placement slot.

[0015] The pedal body is provided with flanges on both sides. When the pedal body is placed in the pedal placement slot, the flanges fit against the side wall of the pedal placement slot.

[0016] A pedal pad is also provided above the pedal body, and the pedal body is provided with a plurality of mounting holes; the pedal pad is provided with mounting pins corresponding to the positions of the mounting holes.

[0017] The surface of the pedal pad is uniformly provided with anti-slip texture.

[0018] Compared with existing technologies, the beneficial effects of this utility model mainly include: 1. By setting multiple shock-absorbing rubbers between the pedal body and the pedal base, this application effectively absorbs and buffers vibrations and impacts from the vehicle body and floor using the elastic deformation of the shock-absorbing rubbers, significantly improving the driver's standing and operating comfort and reducing fatigue during long-term operation. 2. The core shock-absorbing element of the pedal shock-absorbing device of this application is a simple shock-absorbing rubber and a shock-absorbing rubber seat that cooperates with the shock-absorbing rubber. This shock-absorbing element simplifies the device, reduces the number of parts and processing difficulty, and significantly reduces manufacturing costs and subsequent maintenance costs. At the same time, the shock-absorbing rubber uses an insert-type snap-fit ​​assembly method, which does not require complicated installation tools, making disassembly and installation convenient and facilitating subsequent maintenance. 3. This application sets a limit switch on the pedal base. The triggering of this limit switch is related to the deformation of the shock-absorbing rubber. When no one is standing, the shock-absorbing rubber does not deform, so the limit switch is not triggered, which can effectively prevent the vehicle from starting accidentally. When the driver stands, the limit switch is triggered to allow the vehicle to run. This design ensures operational safety. 4. This application, through the cooperation of positioning pins and pin holes, not only facilitates the installation of the pedal body, but also restricts the movement direction of the pedal body, which can effectively prevent slippage or misalignment when subjected to force, ensuring the stability and structural integrity of the pedal body during use. At the same time, the design of the pedal placement groove and the pedal body flange further enhances the lateral stability of the pedal body in the base.

[0024] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the scope of this utility model.

[0025] Example 1 Embodiment 1 provides a foot pedal shock absorption device for a transport vehicle. The foot pedal shock absorption device includes a foot pedal base 7 connected to the body of the transport vehicle, and a foot pedal body 2 placed on the foot pedal base 7. A plurality of shock-absorbing rubber seats 3 are correspondingly provided on the foot pedal body 2 and the foot pedal base 7. A plurality of shock-absorbing rubbers 5 are provided between the foot pedal body 2 and the foot pedal base 7, and the two ends of the shock-absorbing rubbers 5 are engaged in the shock-absorbing rubber seats 3.

[0026] This application utilizes multiple damping rubbers 5 between the pedal body 2 and the pedal base 7 to effectively absorb and buffer vibrations and impacts from the vehicle body and floor by means of the elastic deformation of the damping rubbers 5. This application uses the simple damping rubbers 5 and damping rubber base 3 as the core components for damping, resulting in a simple structure that, while providing good damping performance, reduces device complexity and lowers manufacturing and maintenance costs.

[0027] The following text, in conjunction with the appendix Figure 1 and appendix Figure 2 A detailed explanation is provided for the shock absorption device for the foot pedal of the transport vehicle provided in Embodiment 1.

[0028] like Figure 1 The illustrated pallet pedal shock absorber includes a pedal base 7 and a pedal body 2, wherein the pedal base 7 is connected to the vehicle body, and the pedal body 2 is placed vertically on the pedal base 7. Personnel stand on the pedal body 2 to operate the vehicle.

[0029] A shock-absorbing device is installed between the pedal body 2 and the pedal base 7. This shock-absorbing device includes multiple shock-absorbing rubbers 5, which can be symmetrically placed at the four corners of the pedal base 7 and the pedal body 2. A shock-absorbing rubber seat 3 is provided at the location where the shock-absorbing rubbers 5 are placed on the pedal body 2 and the pedal base 7. The shock-absorbing rubber seat 3 is a round cover, and the upper and lower ends of the shock-absorbing rubbers 5 are locked in the shock-absorbing rubber seat 3.

[0030] The damping rubber 5 is conical in shape and symmetrically arranged at the top and bottom. The vertical cross-section of the damping rubber 5 is conical, and the horizontal cross-section is circular. The diameter of the top and bottom ends of the damping rubber 5 is larger than the diameter of the middle part, and the top and bottom ends of the damping rubber 5 transition evenly towards the middle position.

[0031] The damping rubber 5 is made of resin. In the initial stage of extrusion, the damping rubber 5 has low hardness and deforms to provide energy absorption (i.e., the upper and lower ends of the damping rubber 5 deform under pressure). At the end of the extrusion, the hardness is high, providing support (i.e., the middle part of the damping rubber 5 does not deform under pressure, providing support).

[0032] The pedal body 2 and the pedal base 7 are connected by a flexible connection through shock-absorbing rubber 5 and shock-absorbing rubber seat 3. Due to this flexible connection, lateral displacement can occur between the pedal body 2 and the pedal base 7. To ensure that the pedal body 2 only moves up and down, the direction of movement of the pedal body 2 needs to be limited. This application provides multiple positioning pins 4 on the pedal body 2, and pin holes 8 corresponding to the positions of the positioning pins 4 on the pedal base 7. When the pedal body 2 is installed on the pedal base 7, the positioning pins 4 are inserted into the pin holes 8. Therefore, when the pedal body 2 moves up and down, it will move up and down according to the direction of movement of the positioning pins 4 within the pin holes 8.

[0033] In Example 1, to ensure operational safety, a limit switch 9 is installed on the pedal base 7. The height of the limit switch 9 is less than the height of the shock-absorbing rubber 5 body; the height of the shock-absorbing rubber 5 under maximum deformation is less than the height of the limit switch 9 (e.g., Figure 2 As shown, the height of the trigger mechanism on the limit switch 9 is greater than the height of the shock-absorbing rubber 5 under maximum deformation. The trigger mechanism will be compressed before the maximum deformation is reached. Before the shock-absorbing rubber 5 deforms, the limit switch 9 is not compressed by the pedal body 2. When a person stands on the pedal body 2, the pedal body 2 moves downwards and compresses the trigger mechanism of the limit switch 9. At this time, the limit switch 9 controls the power supply of the transport vehicle, allowing the person to operate the transport vehicle. When the person is not on the pedal body 2, because the height of the shock-absorbing rubber 5 is greater than the trigger mechanism of the limit switch 9, the limit switch 9 is not triggered, and the power supply to the transport vehicle remains disconnected. By setting the limit switch 9, it is ensured that the transport vehicle will operate normally only when the person is in the correct operating position (for example, the limit switch 9 will only be triggered when the shock-absorbing rubber 5 is close to its maximum deformation or when the trigger mechanism of the limit switch 9 is under stable compression).

[0034] A pin hole 8 is provided on the pedal base 7 that is close to the limit switch 9 on one side. A positioning pin 4 corresponding to the position of the pin hole 8 is provided on the pedal body 2. The positioning pin 4 and the pin hole 8 are provided on one side of the limit switch 9 to ensure that the pressing direction of the limit switch 9 remains vertical and does not cause lateral displacement. Figure 1 Only two positioning pins 4 and pin holes 8 are set in the middle. In actual installation, more positioning pins 4 and pin holes 8 can be set to increase the stability of movement.

[0035] The pedal base 7 is provided with a square pedal placement groove 6; the pedal body 2 is placed in the pedal placement groove 6. Flanged plates 11 are provided on both sides of the pedal body 2. When the pedal body 2 is placed in the pedal placement groove, the flanged plates 11 fit against the side wall of the pedal placement groove. The design of the pedal placement groove 6 and the flanged plates 11 of the pedal body 2 provides displacement restriction for the movement of the pedal body 2. Combined with the positioning pin 4 and pin hole 8, this further improves the stability of the movement of the pedal body 2.

[0036] A pedal pad 1 is also provided above the pedal body 2. The pedal body 2 has several mounting holes 10. The pedal pad 1 has mounting pins corresponding to the positions of the mounting holes 10. The pedal pad 1 is assembled and disassembled through the mounting pins and mounting holes 10, which has the advantages of convenient and efficient disassembly. In order to improve the anti-slip effect, the surface of the pedal pad 1 is uniformly provided with anti-slip textures. The anti-slip textures can be of any shape, and the anti-slip textures can be provided in the form of upward convex anti-slip textures or grooves with corresponding textures opened on the pedal pad 1.

Specific examples have been used to illustrate the structure and working principle of this utility model. The descriptions of the embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
