[0021] Figure 1 FIG is a schematic diagram of the three-dimensional structure of the accelerator pedal limiting and positioning device according to one embodiment of the present invention. Figure 1 As shown, a throttle pedal limiting and positioning device according to a preferred embodiment of the present invention is used to limit and position the throttle pedal. The throttle pedal includes a base, a connecting rod and a pedal, and the pedal is fixed to the base by the connecting rod. The throttle pedal limiting and positioning device includes: a base plate 1, a lifting screw 2, a support slide 3, an internal threaded sleeve 4, a sleeve 5, a first support rod 6 and a limiting rod 7. One end of the base plate 1 is used to be fixedly connected to the bottom of the base of the throttle pedal. The lifting screw 2 is vertically arranged on the other end of the base plate 1. The support slide 3 is vertically fixed on the other end of the base plate 1 and is located on one side of the lifting screw 2. The internal threaded sleeve 4 is threadedly sleeved on the lifting screw 2 so as to be movable longitudinally. The sleeve 5 is sleeved on the support slide 3. The two ends of the first support rod 6 are respectively fixedly connected to the opposite ends of the internal threaded sleeve 4 and the sleeve 5 in a transverse direction. One end of the limiting rod 7 is laterally fixedly connected to the end of the inner thread sleeve 4 away from the first support rod 6, and the limiting rod 7 is located at the bottom of the connecting rod of the accelerator pedal. Wherein, the limiting rod 7 is used to limit the pedal of the accelerator pedal.

[0022] In one embodiment of the present invention, a plurality of fixing holes 8 are formed on one end of the bottom plate 1 , and the bottom plate 1 is fixedly connected to the bottom of the base by a plurality of bolts passing through the plurality of fixing holes 8 .

[0023] In one embodiment of the present invention, a screw seat hole 9 is formed on the other end of the base plate 1 , and the lifting screw 2 is vertically fixed in the screw seat hole 9 .

[0024] In one embodiment of the present invention, the accelerator pedal limiting and positioning device further includes a limiting nut 10 , which is screwed onto the lifting screw 2 and located above the internal threaded sleeve 4 .

[0025] In one embodiment of the present invention, the accelerator pedal limiting and positioning device further includes a limiting stopper sleeve 11 , which is sleeved on the lifting screw 2 and located above the limiting nut 10 .

[0026] In one embodiment of the present invention, the accelerator pedal limiting and positioning device further includes a second support rod 12 , and both ends of the second support rod 12 are transversely fixedly connected to the supporting slide rod 3 and the limiting stopper sleeve 11 .

[0027] In one embodiment of the present invention, the throttle pedal limiting and positioning device also includes a knob 13, which is fixed on the top of the lifting screw 2. By rotating the knob 13, the internal threaded sleeve 4 and the lifting screw 2 can be displaced, thereby driving the sliding sleeve 5 and the limiting rod 7 to rise and fall together.

[0028] In one embodiment of the present invention, the accelerator pedal limiting and positioning device further includes a third support rod 14 , one end of the third support rod 14 is vertically fixedly connected to the other end of the limiting rod 7 .

[0029] In one embodiment of the present invention, the accelerator pedal limiting and positioning device further includes a spring shaft 15 fixed to the other end of the third support rod 14. Two positioning slots 17 are defined in the spring shaft 15, and the two positioning slots 17 are arranged at 90°.

[0030] In one embodiment of the present invention, the accelerator pedal limiting and positioning device further includes a positioning rod 16, which is connected to the spring shaft 15 and can be pulled out and rebounded. The rod 16 is located in one of the two positioning slots 17. When the rod 16 is located in one of the positioning slots 17, the rod 16 is located above the pedal, thereby maintaining the pedal in a fixed position. When the rod 16 is located in the other positioning slot 17, the rod 16 is located on one side of the pedal.

[0031] In practical applications, the accelerator pedal limiting and positioning device of the present invention can limit the accelerator pedal of the entire vehicle, and is used to allow the driver to quickly and accurately step on the specified throttle opening when performing a vehicle acceleration test. It can also be used to prevent over-acceleration. The accelerator pedal of the entire vehicle can be positioned to maintain the accelerator pedal at a certain opening when performing a vehicle constant speed test. The knob 13 is used to adjust the height of the limit rod 7, which is convenient and fast. The lifting rod uses threads to ensure smooth and accurate height adjustment. The positioning rod 16 is connected to the rotating shaft with a spring and can be rotated by pulling it out horizontally. After being inserted into the positioning slot 17, it automatically returns to its original position and locks to prevent loosening. Two positioning slots 17 are used for positioning at 90 degrees, and positioning and resetting are performed in one step, which is convenient and fast and does not affect normal driving.

[0032] The accelerator pedal limiting and positioning device of the present invention is used to be installed on the whole vehicle together with the accelerator pedal. The lifting screw rod 2 and the internal threaded sleeve 4 are threadedly matched. The lifting screw rod 2 is limited by the top device and the bottom seat hole. By rotating the knob 13, the internal threaded sleeve 4 and the screw rod produce relative displacement, driving the sliding sleeve 5 and the limiting rod 7 to rise and fall together. The limiting rod 7 is below the connecting rod of the accelerator pedal. When the accelerator pedal is stepped on, the connecting rod of the accelerator pedal is blocked by the limiting rod 7, thereby achieving throttle limiting. Because when performing a whole vehicle acceleration test, the driver is required to quickly step on the specified accelerator position, there is no need to adjust it slowly by stepping on it bit by bit, and it can be easily adjusted to various positions. In addition, it can also be used in training vehicles to prevent trainees from stepping on the accelerator too hard and stepping on it all the way to the bottom.

[0033] Positioning rod 16, located above the accelerator pedal's connecting rod, serves to free the driver's foot from pressing the pedal constantly during a constant-speed test, maintaining the accelerator in a fixed position and saving effort. Positioning rod 16 is pulled out and snapped into its vertical slot when not in use, ensuring normal accelerator operation. To position the accelerator, simply pull positioning rod 16 out and snap it into its horizontal slot. The accelerator pedal's connecting rod is then clamped between stop rod 7 and positioning rod 16, effectively positioning the accelerator pedal. Once positioned, knob 13 can be rotated to fine-tune the accelerator's position for accurate throttle opening.

[0034] In summary, the accelerator pedal limiting and positioning device of the present invention has a simple and reasonable structure, can limit and position the accelerator pedal, is easy to install and adjust, has low cost, and high testing efficiency.
