Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically a mechanically interlocked double pedal mechanism. Background Technology

[0002] In the industrial material handling sector, forklifts are widely used as essential logistics equipment, and their direction of travel is directly affected by the control method, impacting operational efficiency and safety. Currently, traditional forklifts generally employ a control mode combining an accelerator pedal and a forward / reverse shift lever. Specifically, the driver controls the forklift's direction of travel by switching the shift lever to forward or reverse gear and simultaneously pressing the accelerator pedal.

[0003] However, this control method has several shortcomings. First, the driver needs to simultaneously monitor the position of the reversing lever and the accelerator pedal, making the operation cumbersome. Especially in high-intensity, high-frequency work environments, this can easily lead to distraction, operational errors, and reduced work efficiency. For example, when frequently loading and unloading in a narrow warehouse, the driver needs to frequently switch levers and precisely control the accelerator pedal, significantly increasing the difficulty and the probability of error. Second, from a safety perspective, since the reversing lever and accelerator pedal are two independent operating components, the lack of an effective interlocking mechanism makes them prone to misoperation. In emergencies, the driver may accidentally press the accelerator pedal without confirming the lever's position, causing the forklift to travel in the opposite direction to the intended direction, potentially leading to collisions and other safety accidents, seriously threatening the safety of personnel and goods. Therefore, a mechanically interlocked dual-pedal mechanism is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a mechanically interlocked double pedal mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanically interlocked double pedal mechanism, including a panel connected to the vehicle body, a toothed plate rotatably connected to the panel, and a forward pedal and a reverse pedal respectively engaged with the toothed plate on both sides. When one of the pedals is pressed, the pedal will drive the toothed plate engaged with it to rotate, and then the rotating toothed plate will drive the other pedal to be raised.

[0006] As a further embodiment of this utility model: an upper cover plate and a lower cover plate are respectively provided above and below the forward pedal and the reverse pedal. A guide rod is provided on the upper cover plate. One end of the guide rod passes through the upper cover plate, the lower cover plate and the guide sleeve in sequence. A nut is provided at one end of the guide rod to keep in contact with the guide sleeve. A spring is provided on the outer circumference of the guide sleeve, with its end connected to the lower cover plate.

[0007] As a further embodiment of this utility model: a connecting shaft is horizontally arranged on the enclosure, and a forward pedal, a brake pedal and a reverse pedal are respectively installed on the connecting shaft, with the brake pedal located between the forward pedal and the reverse pedal.

[0008] As a further embodiment of this utility model: the end face of the toothed plate is provided with a rotating shaft, and the end of the rotating shaft passes through the surrounding plate and is connected to the angle sensor.

[0009] As a further embodiment of this utility model: the number of guide rods is four, and the four guide rods are respectively set at the four corners of the upper cover plate.

[0010] As a further embodiment of this utility model: each of the four corners of the lower cover plate forms a bracket that bends toward the upper cover plate, and each of the brackets is provided with a through hole for the guide rod to pass through, the inner diameter of the through hole being smaller than the outer diameter of the guide sleeve.

[0011] As a further embodiment of this utility model: the end of the guide rod near the guide sleeve is provided with an external thread, and the inner diameter of the guide sleeve is larger than the outer diameter of the guide rod.

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

[0013] This application utilizes a mechanical interlocking mechanism between the toothed plate and the pedal coupling transmission to achieve physical restriction between the pedals. When the forward pedal is operated, the reverse pedal is forcibly raised by the mechanical structure, and vice versa. This completely eliminates the risk of forklift misdirection due to misoperation, effectively avoiding safety accidents such as collisions, providing reliable safety protection for operators and goods, and reducing enterprise safety accident losses and potential risks. In addition, it abandons the complex operation method of traditional forklifts that requires coordination of a reversing lever and accelerator pedal for forward and reverse movement. Forward and reverse functions are directly achieved through dual pedals, eliminating the need for drivers to frequently switch gears. The operation steps are more intuitive and simple, significantly reducing the difficulty of operation. It is especially suitable for high-frequency and high-intensity operation scenarios, greatly improving work efficiency. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-6 In this embodiment of the utility model, a mechanically interlocked double pedal mechanism includes a side panel 1 connected to the vehicle body. A toothed plate 2 is rotatably connected to the side panel 1. A forward pedal 3 and a backward pedal 5 are respectively provided on both sides of the toothed plate 2 and mesh with it. When one of the pedals is pressed, the pedal will drive the toothed plate 2 to rotate, and then the rotating toothed plate 2 will drive the other pedal to be raised.

[0023] Specifically, the side panel 1 is fixed to the vehicle body, providing stable support for other components. The side panel 1 has an overall U-shaped structure. The toothed plate 2 is fixed inside the side panel 1 and is parallel to the opening direction of the side panel 1. The toothed plate 2 can rotate inside the side panel 1. A connecting shaft 12 is horizontally arranged on the side panel 1. The forward pedal 3, brake pedal 4, and reverse pedal 5 are respectively mounted on the connecting shaft 12 and can rotate around the shaft. The forward pedal 3 and reverse pedal 5 are symmetrically arranged on both sides inside the side panel 1, and both have teeth at their ends. The gear structure meshes with the toothed plate 2. When the forward pedal 3 is pressed, it rotates around the connecting shaft 12, causing the gear structure at the end of the pedal to move upward. This drives the toothed plate 2 to rotate from above towards the reverse pedal 5 (clockwise). The rotation of the toothed plate 2 further drives the reverse pedal 5, which meshes with it, causing the end of the reverse pedal 5 that is closer to the toothed plate 2 to move downward and the end that is farther away from the toothed plate 2 to lift upward. Conversely, when the reverse pedal 5 is pressed, the action is the opposite of pressing the forward pedal 3, achieving the corresponding reverse linkage effect.

[0024] The above technical solution can achieve interlocking between the two pedals. When the forward pedal 3 is pressed down, the reverse pedal 5 is raised, and the reverse pedal 5 cannot be pressed down, thus achieving the interlocking effect between the forward pedal 3 and the reverse pedal 5.

[0025] Please see Figure 4 In one embodiment, preferably, an upper cover plate 6 and a lower cover plate 7 are respectively provided above and below the forward pedal 3 and the reverse pedal 5. A guide rod 8 is provided on the upper cover plate 6. One end of the guide rod 8 passes through the upper cover plate 6, the lower cover plate 7 and the guide sleeve 9 in sequence. One end of the guide rod 8 is provided with a nut 10 that keeps in contact with the guide sleeve 9. The outer circumferential surface of the guide sleeve 9 is provided with a spring 11 whose end is connected to the lower cover plate 7.

[0026] Specifically, there are four guide rods 8, which are respectively located at the four corners of the upper cover plate 6. Each of the four corners of the lower cover plate 7 forms a bracket that bends towards the upper cover plate 6. Multiple brackets have through holes for the guide rods 8 to pass through. The inner diameter of the through holes is smaller than the outer diameter of the guide sleeve 9, allowing the upper cover plate 6 and lower cover plate 7 to be fitted above and below the toothed plate 2. A guide sleeve 9 is fitted at the position of the guide rod 8 below the lower cover plate 7 to limit the range of motion of the lower cover plate 7. Simultaneously, a nut 10 is tightened onto the end of the guide rod 8 to fix the position of the guide sleeve 9 on the guide rod. The guide sleeve 9 consists of two cylindrical structures with different diameters: the smaller diameter part is used to install the spring 11, and the larger diameter part is used to abut one end of the spring 11; the spring 1... The other end of 1 is connected to the lower cover plate 7. When the pedal (forward pedal 3 or backward pedal 5) is pressed down, the surfaces of the forward pedal 3, the backward pedal 5, and the toothed plate 2 that meshes with them will push up the upper cover plate 6 and the lower cover plate 7, causing the spring 11 on the guide rod 8 to be compressed, thereby causing the upper and lower cover plates to move downward relative to each other. When the pedal is released, under the restoring force of the spring 11, the upper cover plate 6 and the lower cover plate 7 return to their original position and press the surfaces of the forward pedal 3, the backward pedal 5, and the toothed plate 2 to return them to their initial position. Through the coordinated action of the guide rod 8, the guide sleeve 9, the spring 11, and the upper and lower cover plates, the guiding, supporting, and automatic reset functions of the pedal assembly are realized. The structure is compact, the action is reliable, and the stability and responsiveness of the overall operation are improved.

[0027] Please see Figure 1-2 In one embodiment, preferably, the end face of the toothed plate 2 is provided with a rotating shaft 13, and the end of the rotating shaft 13 passes through the enclosure plate 1 and is connected to the angle sensor 14.

[0028] Specifically, angle sensor 14 is in the neutral position when the pedal is not pressed. When the forward pedal 3 is pressed, it will drive the toothed plate 2 to rotate clockwise. The toothed plate 2 will drive the angle sensor 14 to rotate clockwise through the rotating shaft 13. The angle sensor 14 sends an analog voltage signal to the controller, and the controller controls the forklift to move forward. When the reverse pedal 5 is pressed, it will drive the toothed plate 2 to rotate counterclockwise. The toothed plate 2 will drive the angle sensor 14 to rotate counterclockwise. The angle sensor 14 sends an analog voltage signal to the controller, and the controller controls the forklift to move backward.

[0029] Please see Figure 4 In one embodiment, preferably, the guide rod 8 has an external thread at one end near the guide sleeve 9, and the inner diameter of the guide sleeve 9 is larger than the outer diameter of the guide rod 8 so that it can be sleeved on the guide rod 8. By tightening the nut 10 on the end of the guide rod 8 with the external thread, the position of the guide sleeve 9 can be restricted, thereby achieving the purpose of axially fixing the guide sleeve 9.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
