Description

Technical Field

[0001] This invention relates to the automotive field, and more particularly to an automotive pedal limiting device. Background Technology

[0002] With the rapid development of new energy vehicles in my country, the regulation and requirements for the automotive industry are becoming increasingly stringent, and vehicles must undergo rigorous testing before leaving the factory. The moose test, as an important test for assessing vehicle chassis stability, is gradually gaining importance among major automakers.

[0003] Then, most new energy vehicles on the market have kinetic energy recovery systems, and some vehicles cannot turn them off. When conducting the moose test, the vehicle needs to perform slalom maneuvers at a constant preset speed. However, the inability to turn off the kinetic energy recovery system causes the vehicle speed to drop during slalom maneuvers, affecting the test results. Furthermore, in such extreme driving conditions as slalom maneuvers, the driver cannot maintain the throttle opening. Therefore, a kind of automotive pedal limiter device is needed in Yuyao.

[0004] Existing pedal limiting devices lack a release mechanism in emergency situations, which can easily lead to accidents if the rider operates them improperly. Furthermore, changes in throttle opening are often achieved through the interaction of a lever and a slot, which depends entirely on the spacing between the limiting slots, resulting in insufficient precision. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide an automotive pedal limiting device with a release device under extreme conditions; an electronically controlled screw replaces the traditional limiting device, making the adjustment of the throttle opening more linear.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vehicle pedal limiting device includes a fixed rod located in the driver's cabin, with both ends of the fixed rod abutting against the driver's cabin floor and upper plate, respectively, and further includes:

[0008] A horizontal limiting frame is vertically inserted into the fixed rod and extends to one side, and a track is provided inside the horizontal limiting frame;

[0009] The power rod includes an electrically controlled screw, a T-shaped slider, and a first rotating column. The T-shaped slider is connected to the track, and the lower end of the electrically controlled screw is axially fixedly connected to the first rotating column.

[0010] The power plate has a second rotating column fixedly connected to its lower end and is rotatably connected to the fixed rod through the second rotating column. Its upper end is rotatably connected to the electric control screw through the first rotating column.

[0011] Preferably, a gear is fixedly connected to one end of the horizontal limiting frame located inside the fixed rod, and the axis of the gear is rotatably connected to the inner sidewall of the fixed rod.

[0012] Preferably, it also includes a positioning pin and a through hole, wherein the positioning pin enters from the outside of the fixing rod through the through hole and engages with the tooth gap of the gear.

[0013] Preferably, the positioning pin includes a snap-fit ​​member and an extension member, the snap-fit ​​member being located on one side of the extension member and forming an axe-shaped structure.

[0014] Preferably, the surface of the power plate is provided with an anti-slip rubber pad.

[0015] Preferably, in the initial state, the power plate is placed at an angle.

[0016] The present invention has the following beneficial effects:

[0017] 1. The gears and axe-shaped locating pins work together to achieve rapid release, reducing the accident rate during testing;

[0018] 2. The electronically controlled screw replaces the traditional limit device, making the adjustment of the throttle opening more linear. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] A vehicle pedal limiting device includes a fixed rod 1 located in the driver's cabin, with both ends of the fixed rod 1 abutting against the driver's cabin floor and upper plate, respectively, and further includes:

[0026] A horizontal limiting frame 2 is vertically inserted into the fixed rod 1 and extends to one side. A track 21 is provided inside the horizontal limiting frame 2.

[0027] The power rod 3 includes an electrically controlled screw 31, a T-shaped slider 32, and a first rotating column 33. The T-shaped slider 32 is connected to the track 21, and the lower end of the electrically controlled screw 31 is axially fixedly connected to the first rotating column 33.

[0028] The power plate 4 has a second rotating column 41 fixedly connected to its lower end and is rotatably connected to the fixed rod 1 through the second rotating column 41. Its upper end is rotatably connected to the electric control screw 31 through the first rotating column 33.

[0029] Preferably, a gear 5 is fixedly connected to one end of the horizontal limiting frame 2 located inside the fixing rod 1, and the axis of the gear 5 is rotatably connected to the inner sidewall of the fixing rod 1.

[0030] Preferably, it also includes a positioning pin 6 and a through hole, wherein the positioning pin 6 enters from the outside of the fixing rod 1 through the through hole and engages with the tooth gap of the gear 5.

[0031] Preferably, the positioning pin 6 includes a snap-fit ​​member 61 and an extension member 62. The snap-fit ​​member 61 is located on one side of the extension member 62 and forms an axe-shaped structure. The snap-fit ​​member 61 engages with the tooth gap of the gear 5.

[0032] Preferably, the surface of the power plate 4 is provided with an anti-slip rubber pad 42.

[0033] Preferably, in the initial state, the power plate 4 is placed at an angle.

[0034] Preparation: First, align the power plate 4 with the accelerator pedal and place it on the accelerator pedal. Then, the two ends of the fixing rod 1 abut against the bottom plate and the top plate of the cockpit, respectively.

[0035] During the test, the tester drove the electronically controlled screw 31, which rotated and extended downward, reducing the angle between the power plate 4 and the cockpit floor. The electronically controlled screw 31, along with the T-shaped slider 32, moved to the left along the track 21 under the force, simulating the action of pressing the accelerator.

[0036] Once the preset speed is reached, the electronically controlled screw 31 stops rotating, thus maintaining the vehicle's current speed.

[0037] In case of an emergency, quickly strike the positioning pin 6 inside the fixed rod 1. The locking part 61 moves into the box until it disengages from the gear 5, causing the horizontal limit frame 2 to lose its limit and its left end to rise, thus removing the pressure on the accelerator pedal.

[0038] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
