Description

Technical Field

[0001] This invention relates to the field of pedal control devices, specifically to a standing-mounted suspended pedal control device and its usage method. Background Technology

[0002] Standing-on forklifts typically use foot pedals. The operator stands on the pedals with both feet, using one foot to control the brake and the other to control the pedal switch. By raising and lowering their feet, the operator controls the forklift's forward and stop movements. When a standing-on forklift encounters potholes or speed bumps, the impact can cause the operator to lose their balance and fall, posing a safety hazard and providing a poor driving experience. Currently, standing-on forklifts do not have brake potentiometers and rely mainly on programming to achieve braking, resulting in poor braking control. Summary of the Invention

[0003] The purpose of this invention is to provide a standing-ride type suspended pedal control device and its usage method to solve the problem that when a standing-ride forklift encounters potholes or speed bumps during operation, the impact may cause the operator to fall due to instability, which poses certain safety hazards and a poor driving experience. In addition, the current standing-ride forklifts rely on programs to achieve deceleration, resulting in poor braking control.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a stand-up forklift suspension pedal control device, installed inside the frame of a stand-up forklift, including a fixed slide, a pedal mounting bracket, and a base plate for the driver to stand on. The fixed slide is fixed to the inner side of the frame of the stand-up forklift, and the base plate is mounted on the pedal mounting bracket. The device is characterized by including a suspension block and a suspension cover. The lower end of the suspension cover is fixedly connected to the pedal mounting bracket. The inner side walls of the suspension cover form a left slide rail and a right slide rail between the suspension block and the fixed slide. The distance between the inner two side walls of the cover matches the length of the suspension block. Floating bearings are provided in both the left and right slides, and the outer diameter of the floating bearings matches the width of the left and right slides. The suspension block is located inside the suspension cover. First spring lugs are provided on the outer two side walls of the suspension cover. Second spring lugs are provided on the left and right side walls of the top of the fixed slide. A tension spring is provided between the first and second spring lugs. An upper limit is provided at the top of the fixed slide, and a lower limit is provided at the bottom of the pedal mounting bracket.

[0005] The lower end face of the base plate is provided with a right pedal mounting bracket, a left pedal mounting bracket, and a pedal spring seat. The right pedal...

[0006] A pedal control box is provided between the mounting bracket and the lower end face of the base plate. A cover is provided on the upper end face of the pedal control box. A K3 pedal switch and a reset spring seat are installed inside the pedal control box. One end of the pedal spring seat is connected to the left pedal mounting bracket, and the other end is connected to the left pedal. A spring is installed on the pedal spring seat. A first movable arm and a second movable arm are provided on the lower end face of the left pedal. The second movable arm has a fixed shaft and also includes a potentiometer bracket and a switch bracket. A potentiometer is installed on one side of the potentiometer bracket. The rotating shaft of the potentiometer is rotatably connected to the fixed shaft via a shift fork plate. The first movable arm is connected to a rotating roller and also includes a baffle and a support. The device includes an ear, a K1 micro switch, and a K2 micro switch. The ear is fixed to the base plate and located on the left and right sides of the first movable arm. The baffle is divided into a side plate and a limiting plate. The left and right baffles are installed on the left and right sides of the first movable arm through the side plate. The limiting plate of the left baffle is located above the side plate, and the limiting plate of the right baffle is located below the side plate. The K1 micro switch and the K2 micro switch are respectively installed on the ear on the left and right sides. The foot of the K1 micro switch is located below the left baffle, and the foot of the K2 micro switch is located above the right baffle. The potentiometer, the K1 micro switch, the K2 micro switch, and the K3 pedal switch are connected to the controller signal. The controller is connected to the brake signal.

[0007] Furthermore, a buffer pad is provided on the first movable arm, and the buffer pad is located between the base plate and the first movable arm, which can play a certain role in shock absorption.

[0008] Further specifying, the potentiometer is installed on one side of the potentiometer bracket, the rotation shaft of the potentiometer passes through the potentiometer bracket, the shift fork is Y-shaped, one end is snapped onto the fixed shaft, and the other end is rotatably connected to the rotation shaft of the potentiometer, one end of the second movable arm is connected to the left pedal, and the other end is connected to the shift fork via the fixed shaft. When the left pedal is released, the potentiometer will output an analog signal according to the rotation angle, which is input to the controller, which controls the output of a corresponding signal to the brake to brake and stop.

[0009] Further defined, the suspended block is convex in shape, and the suspended sliding cover is a channel steel structure with one side open and three sides closed. The inner two side walls of the suspended sliding cover form a left slide and a right slide between the left and right side walls of the suspended block and the fixed slide seat, respectively. Support rods are provided in the left and right slides, and floating bearings are provided on the support rods. The suspended block is located inside the suspended sliding cover and can move up and down under the action of the floating bearings.

[0010] Further, the suspension block has a central slide with openings at the top and bottom. A limiting bearing is provided on the inner side of the front wall of the suspension cover. A centering rod is provided between the central slide and the suspension cover. The limiting bearing is installed on the centering rod. The size of the limiting bearing matches the size of the central slide. The limiting bearing is located inside the central slide, which can effectively prevent the suspension block from sliding left and right when it moves up and down inside the suspension cover.

[0011] Furthermore, both the upper and lower limit positions are equipped with polyurethane springs. The lower limit position acts as a lower limit when it contacts the bottom of the frame, and the polyurethane springs serve as shock absorbers.

[0012] Further specifying, a standing-mounted suspension pedal control device and its usage method include the following steps:

[0013] S1: The left foot controls the brake pedal and the right foot controls the enable pedal. The brake pedal contains a K1 micro switch and a K2 micro switch, and the enable pedal contains a K3 pedal switch. When the brake pedal and enable pedal are pressed by the two feet respectively, the K1 micro switch is closed and the K2 micro switch is open, and the stand-on forklift moves normally.

[0014] S2: When the right foot is lifted, the pedal control box cover is reset by the reset spring seat, disconnecting from the K3 pedal switch, and the brake is applied quickly to stop the vehicle.

[0015] S3: If both feet press the brake pedal and the enable pedal respectively, and both micro switches K1 and K2 close, then the vehicle must be stopped immediately and a fault report must be submitted.

[0016] S4: When the stand-on forklift is in normal operation, lightly lift the brake pedal. At this time, the first and second movable arms move upward as the brake pedal is lifted. The second movable arm will drive the shift fork plate to rotate, and both the left and right baffles will move upward. Keep the left and right baffles from contacting the K1 and K2 microswitches. At this time, the K1 and K2 microswitches are open, and the K3 pedal switch is closed. The potentiometer will output an analog signal according to the rotation angle of the shift fork plate, which is input to the controller. The controller outputs a corresponding signal to the brake to brake and stop. By analyzing the road conditions, the braking distance and speed can be freely controlled according to the depth of the brake pedal.

[0017] S5: In case of an emergency requiring immediate braking, lift your left foot immediately. At this time, both the left and right brake pads will move upwards. The left brake pad will move away from the K1 microswitch, disengaging it. The right brake pad will then contact the support leg of the K2 microswitch, closing it and immediately applying the brakes.

[0018] The advantages of this invention over the current technology are as follows:

[0019] 1. Currently, when a stand-on forklift encounters potholes or speed bumps during operation, the impact can cause the operator to lose their balance and fall, posing a safety hazard and a poor driving experience. This problem is now being addressed by using suspension blocks, floating bearings, limit bearings, and tension springs. The driver stands on the base plate, and with the help of tension springs and floating bearings, the base plate will move up and down when encountering speed bumps or potholes. At the same time, polyurethane springs are installed on the upper and lower limits to absorb shocks.

[0020] 2. At present, deceleration is mostly achieved through programs, resulting in poor braking control. Potentiometers are now used to control the braking deceleration rate and improve driving safety. Attached Figure Description

The limiting bearing 10 is mounted on the centering rod, and its size matches that of the middle slide rail 8. The limiting bearing 10 is located inside the middle slide rail 8, which can effectively prevent the floating block 4 from sliding left and right when it moves up and down inside the floating slide cover 5. First spring lugs 11 are provided on the outer side walls of the floating slide cover 5, and second spring lugs 12 are provided on the left and right side walls of the top of the fixed slide block 2. A space is provided between the first spring lugs 11 and the second spring lugs 12. There is a tension spring 13. One end of the tension spring 13 is fixed to the hook point of the first spring support 11, and the other end is fixed to the hook point of the second spring support 12. When the driver stands on the base plate 1, the base plate 1 will float up and down under the action of the tension spring 13 and the floating bearing 9. An upper limit position 14 is provided at the top of the fixed slide 2, and a lower limit position 15 is provided at the lower end of the pedal mounting bracket 3.

[0032] A right pedal mounting bracket 17 is provided on the lower right side of the base plate 1. The right pedal mounting bracket 17 and the lower right side of the base plate 1 form a cavity. A pedal control box 18 is provided in the cavity. A cover 19 is provided on the upper end of the pedal control box 18. A K3 pedal switch 20 and a reset spring seat 21 are installed in the pedal control box. The setting and connection relationship of the K3 pedal switch 20 and the reset spring seat 21 in the pedal control box 18 are prior art and will not be described in detail here. A left pedal mounting bracket 22 is provided on the lower left side of the base plate 1. A through groove is opened on the left side of the base plate 1, and a pedal spring seat 23 is also included. One end of the pedal spring seat 23 is connected to the left pedal mounting bracket 22, and the other end is connected to the left pedal 24. A reset spring is installed on the pedal spring seat 23. The left pedal 24 is located in a through groove in the base plate 1. A first movable arm 25 is provided at the front end of the lower end face of the left pedal 24, and a second movable arm 26 is provided at the rear end. A fixed shaft 27 is provided on the second movable arm 26. It also includes a potentiometer bracket 28 and a switch bracket 29. The switch bracket 29 includes a rotating roller 30. One end of the first movable arm 25 is connected to the left pedal 24, and the other end is connected to the rotating roller 30. The potentiometer bracket 28 and the switch bracket 29 are both installed on the lower end face of the base plate 1. The potentiometer bracket 28 is located behind the left pedal 24, and the switch bracket 29 is located in front of the left pedal 24. A potentiometer 31 is installed on one side of the potentiometer bracket 28. The rotation shaft of the potentiometer 31 passes through the potentiometer bracket 28 and includes a shift fork plate 32. The shift fork plate 32 is Y-shaped. One end is snapped onto the fixed shaft 27, and the other end is rotatably connected to the rotating shaft of the potentiometer 31. One end of the second movable arm 26 is connected to the left pedal 24, and the other end is connected to the shift fork plate 32 through the fixed shaft 27. When the left pedal 24 is released, the potentiometer 31 will output an analog signal according to the rotation angle, which is input to the controller, which controls the output of a corresponding signal to the brake to brake and stop. The first movable arm 25 is connected to the rotating roller 30. A buffer pad 33 is provided on the first movable arm 25. The buffer pad 33 is located between the base plate 1 and the first movable arm 25 and includes a baffle, a support lug 35, a K1 micro switch and a K2 micro switch. The support lug 35 is fixed on the base plate 1 and located on the left and right sides of the first movable arm 25. The baffle is L-shaped and is divided into a side plate 37 and a limit plate. Left baffle 38, left baffle 34, and right baffle 36 are all mounted on the left and right sides of the first movable arm 25 via side plates. The limiting plate 38 of the left baffle 34 is located above the side plate 37, and the limiting plate 38 of the right baffle 36 is located below the side plate 37. Microswitches K1 39 and K2 40 are respectively mounted on the left and right side lugs 35, located between the lugs 35 and the first movable arm 25. The baffles are located between the lugs 35 and the switch bracket 29. The support foot 41 of K1 microswitch 39 is located below the left baffle 34, and the support foot 41 of K2 microswitch 40 is located above the right baffle 36. When the left foot presses down on the left pedal 24, the first movable arm 25 moves downward, moving the baffles along with it. The left baffle 34 presses down on the support foot 41 of K1 microswitch 39.When micro switch K1 39 closes, it begins to operate. The right stop 36 moves downwards, away from the support foot 41 of micro switch K2 40. Micro switch K2 40 then opens, the brake is released, and the forklift can move.

[0033] The method of using a standing-mounted suspension pedal control device is as follows: the left foot controls the brake pedal, and the right foot controls the enable pedal. The brake pedal includes a K1 microswitch 39 and a K2 microswitch 40. The enable pedal includes a K3 pedal switch 20. The stand-on forklift can only move normally when both feet press the brake pedal and the enable pedal respectively. At this time, the K3 pedal switch 20 is closed, the left baffle 34 presses down on the support leg 41 of the K1 microswitch 39, closing the K1 microswitch 39. The right baffle 36 moves downwards, away from the support leg 41 of the K2 microswitch 40, disengaging the K2 microswitch 40. When the stand-on forklift is in normal operation, a slight release of the brake pedal causes the first movable arm 25 and the second movable arm 26 to move upwards. The second movable arm 26 rotates the shift fork plate 32, causing both the left and right baffles 34 and 36 to move upwards, keeping them from contacting the K1 microswitch 39 and the K2 microswitch 40. At this time, the K1 microswitch 39 and the K2 microswitch 40 are disengaged. When pedal switch 20 is closed, potentiometer 31 outputs an analog signal based on the rotation angle of shift fork 32 (i.e., the depth of the brake pedal). This signal is input to the controller, which then outputs a corresponding signal to the brake to stop the brake. The braking distance can be freely controlled based on the depth of the brake pedal. In case of an emergency requiring immediate braking, the left foot can be lifted immediately. At this time, both the left and right baffles 34 and 36 move upward. The left baffle 34 moves away from the K1 microswitch 39, disengaging the K1 microswitch 39. The right baffle 36 contacts the support leg 41 of the K2 microswitch 40, closing the K2 microswitch and immediately applying the brake. When the right foot is lifted and the enable pedal is released, the cover 19 of the pedal control box 18 lifts upward, no longer contacting the K3 pedal switch 20 inside the pedal control box 18. The K3 pedal switch 20 then disengages, allowing for rapid braking as well.

[0034] The above provides a detailed description of a standing-mounted suspension pedal control device and its usage method provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its scope, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
