Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle pedal technology, and in particular to an interlocking dual accelerator pedal device. Background Technology
[0002] Most electric forklifts on the market are currently controlled by a manual direction switch and an accelerator pedal. The direction switch determines forward and reverse movement, while the accelerator pedal determines acceleration and speed. A small number of electric forklifts also exist with dual accelerator pedals, eliminating the manual direction switch and using two separate pedals to control forward, reverse, and speed. These two pedals are typically positioned left and right and linked by a mechanism. For example, when the forward accelerator pedal is depressed, the reverse accelerator pedal is raised, and vice versa. The linkage mechanism for the two pedals often uses a spatial linkage mechanism, but this has drawbacks such as large space requirements and complex structure. It often needs to be considered in sync with other moving parts to avoid interference, such as the braking system, resulting in poor versatility. Therefore, for electric forklifts with dual accelerator pedals, the primary challenge is to construct a simple, reliable, and widely applicable linkage mechanism. Utility Model Content

[0016] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0017] Traditional linkage mechanisms between the left and right accelerator pedals use linkage mechanisms, but linkage mechanisms need to be arranged along a straight line or at a specific angle, occupying a large amount of three-dimensional space. Especially in space-constrained areas such as electric forklift chassis, they are prone to motion interference with components such as the vehicle's braking system and steering mechanism.
[0018] Therefore, see Figure 1-2 As shown, this embodiment provides an interlocking dual accelerator pedal device, including a fixed plate 10. The upper surface of the fixed plate 10 is provided with a left accelerator pedal 20 and a right accelerator pedal 21. The right accelerator pedal 21 and the left accelerator pedal 20 have the same structure. The lower surface of the fixed plate 10 is movably connected to a drive cable 30. The drive cable 30 includes a sleeve 31 and a spindle 32. The spindle 32 is movably disposed in the sleeve 31, and the two ends of the spindle 32 extending out of the sleeve 31 are respectively provided with connectors for connecting the left accelerator pedal 20 and the right accelerator pedal 21. The bottom of the fixed plate 10 is provided with a fixing bracket 40 for fixing the sleeve 31.
[0019] In this embodiment, the sleeve 31 can be bent according to the spatial orientation, such as along the edge of the fixed plate 10 or the gap between equipment, without the need to reserve additional space for the linkage movement, which greatly reduces the space occupied. The spindle 32 is a flexible structure that can move within the sleeve 31. When one accelerator pedal 23 is pressed, the other accelerator pedal 23 is pulled up. In addition, the wiring of the drive cable 30 can be flexibly adjusted, without rigid interference with the braking system, steering mechanism, etc., without the need for additional avoidance structure design, and has high versatility.
[0020] See Figure 4As shown, the left accelerator pedal 20 includes a base plate 22 and a pedal 23. The base plate 22 is fixedly connected to the top of the fixing plate 10. One end of the base plate 22 is rotatably connected to the pedal 23, and a pedal return torsion spring 24 is provided around its rotational joint. A swing arm 25 is rotatably connected to the bottom of the pedal 23, and a swing arm return torsion spring 26 is provided around its rotational joint. A roller 27 is provided at the end of the swing arm 25. A linkage plate 28 penetrating the base plate 22 is fixed to the bottom of the pedal 23. In this embodiment, the two ends of the pedal return torsion spring 24 are fixed to the base plate 22 and the linkage plate 28, respectively, to ensure that the left accelerator pedal 20 returns to its original position after release. Under the action of the swing arm return torsion spring 26, the roller 27 can continuously contact the base plate 22 and roll on the base plate 22. When the pedal 23 is pressed, the pedal 23 can rotate around its axis, and the swing arm 25 can also rotate around its axis. The roller 27 at the end continues to contact the base plate 22 and can roll on the base plate 22. When no force is applied to the pedal 23, the pedal 23 returns to its initial state under the action of the pedal return torsion spring 24. In this embodiment, the linkage plate 28 is arc-shaped.
[0021] See Figure 2 As shown, in this embodiment, both ends of the sleeve 31 are provided with threaded sleeves 310, which are connected to the fixed bracket 40. Multiple nuts and washers 311 are provided on the threaded sleeves 310. These are used to fasten the sleeves 31 to the fixed bracket 40 and allow for appropriate adjustment of their position as needed.
[0022] See Figure 3 As shown, in one feasible embodiment, the fixed bracket 40 has a bent portion 41 on the side facing the sleeve 31, and a strip groove 42 is formed on the bent portion 41. The fixed bracket 40 is connected to the fixed plate 10, the bent portion 41 is connected to the threaded sleeve 310, and the two end mandrels 32 extend to the rear of the strip groove 42 and are connected to the linkage plates 28 of the left accelerator pedal 20 and the right accelerator pedal 21, respectively. The bending angle of the bent portion 41 is 90° to 135°, which is used to guide the direction of the mandrel 32 and adjust the position of the mandrel 32.
[0023] See Figure 2-4 As shown, the fixed plate 10 has through holes 11 for the left accelerator pedal 20 and the right accelerator pedal 21 to extend to the lower surface of the fixed plate 10 and connect with the spindle 32. In this embodiment, the through holes 11 are used for the linkage plate 28 to pass through the fixed plate 10 and connect with the spindle 32. In addition, the fixed plate 10, the base plate 22 and the fixed bracket 40 are also provided with mounting holes 43 corresponding to the hole positions, which can be used to fix the fixed plate 10, the base plate 22 and the fixed bracket 40 together.
[0024] See Figure 2 As shown, in this embodiment, the connector includes a fork-shaped member 33, which is connected to the linkage plate 28. The fork-shaped member 33 includes two symmetrical support arms, and the linkage plate 28 is located between the two support arms and fixed by a pin.
[0025] In this embodiment, a sensor 29 is provided on the side wall of the pedal 23 to detect the relative rotation angle between the swing arm 25 and the pedal 23. The output of the sensor 29 is connected to the automatic control system of the forklift. The sensor 29 can detect the rotation angle between the swing arm 25 and the pedal 23, and then transmit the analog signal to the vehicle controller to determine the vehicle's direction of travel and speed.
[0026] Based on the above embodiments, the interlocking dual accelerator pedal device of this utility model, taking the right accelerator pedal 23 being depressed as an example, operates as follows: When the right accelerator pedal 21 is pressed, under the action of the pedal return spring 24 and the swing arm return spring 26, the roller 27 continues to be in contact with the base plate 22. While the pedal 23 rotates around the axis, it drives the linkage plate 23 to move, causing the spindle 32 to move inside the sleeve 31. Since the spindle 32 makes the left pedal 23 and the right pedal 23 linked, the pedal 23 of the left accelerator pedal 20 will rotate and lift upward under the driving force of the spindle 32. Correspondingly, when the left accelerator pedal 20 is pressed, the process is similar to the above, and will not be described in detail here.
[0027] When the left and right accelerator pedals are pressed simultaneously, the sensors 29 of both accelerator pedals are disconnected due to the constraint of the spindle 32, and will not be triggered at the same time, ensuring the safe and reliable operation of the vehicle.
[0028] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
[0029] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
