AI Technical Summary
The existing car speed limit controllers cannot adapt to slope changes. When the vehicle speed drops when going uphill, the driver needs to increase the accelerator, but it may cause the vehicle to be too fast and the safety depends on the driver's control. Some vehicles are prone to slip on the slope, resulting in collisions or safety accidents.
A speed limit controller for automobiles is designed, including a power compensation mechanism and a restriction mechanism. The power compensation mechanism automatically increases the throttle slightly when going uphill through the energy-consuming pulling structure and oil replenishing structure to avoid slope slipping; the restriction mechanism uses electronic level and electronic control box to monitor the vehicle's attitude in real time, triggers the air rod body to shrink, drive the limit stop to exit, allow the counterweight block to pull down the pedal body, and increase the throttle.
It effectively improves driving safety and reliability, avoids the situation where the vehicle slips when going uphill, and prevents the driver from increasing the throttle in a targeted manner to ensure driving safety.

[0030] The limiting mechanism 5 includes a limiting groove 501, a gas rod body 502 and a limiting block 503. The limiting groove 501 is arranged on the right side of the wire groove 402, and the gas rod body 502 is fixedly installed inside the limiting groove 501. The transmission end of the gas rod body 502 is fixedly connected to the limiting block 503. The limiting mechanism 5 also includes a mounting groove 504 and an electric control box 505.

[0031] See also Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 Initially, the power compensation mechanism 4 adopts a non-energy-consuming pulling structure and an oil replenishing structure, the pulling structure is a counterweight slide 403, a counterweight block 404, a connecting steel wire 405 and a connecting block 408, the oil replenishing structure is an oil replenishing pipeline 407, and the limiting mechanism 5 adopts an electric control structure and a limit structure, the electric control structure is an electric control box 505, a backup battery 506 and an electronic level 508, and the limit structure is a gas rod body 502 and a limit block 503. Before activation, it is necessary to determine the installation method of the speed limit controller for the vehicle. For the traditional throttle cable structure , the connecting wire 405 can be connected to the throttle cable. The speed limit controller for automobiles is an electronic throttle for conventional automobiles, so the connecting wire 405 is connected to the pedal body 3, and the installation and adjustment operation can be performed according to the specific situation. After the installation operation is completed, when the vehicle is in an uphill state, the electronic level 508 in the limiting mechanism 5 detects the level change and transmits the information to the electric control box 505, and the electric control box 505 brakes the gas rod body 502, and the gas rod body 502 is pulled upward to the limit block 503, so that The limit stopper 503 no longer limits the position of the counterweight 404. At this time, the counterweight 404 will pull the connecting wire 405 downward under the action of gravity, thereby causing the connecting wire 405 to pull down the pedal body 3, exerting a downward pulling force on the pedal body 3. The magnitude of this downward pulling force depends on the gravity of the counterweight 404. This downward pulling force will cause the pedal body 3 to slightly increase the throttle, thereby putting the car engine in a refueling state, thereby providing power compensation for the car speed reduction caused by going uphill, so that the driver does not need to increase the throttle specifically. When the engine is in the refueling state, the car is prevented from sliding down the slope; the gravity of the counterweight 404 is limited in range: through searching, it is known that the force required to pull down the accelerator pedal is about 2.0±0.5 kg-force, assuming that the required force is 3 kg-force (this force can effectively pull the pedal body 3 without excessively increasing the throttle), the counterweight 404 is made of iron, which is low in cost and environmentally friendly. The density of iron is about 7900 kg / m3. Substituting it into the volume formula, it can be obtained that the volume of the counterweight 404 is about: 380 cubic centimeters;
[0032] The power compensation mechanism 4 adopts an energy-free pulling structure and an oil replenishing structure. During the uphill process, the power compensation mechanism 4 can exert a downward pulling force on the pedal body 3 through the energy-free pulling structure, slightly increase the throttle, and perform power compensation for the slowdown of the car caused by the uphill, so that the driver does not need to increase the throttle specifically, and avoids the car from sliding down the slope, effectively improving driving safety and reliability; the oil replenishing structure can replenish lubricating oil for the counterweight block 404, and the sliding stability of the counterweight block 404 can be ensured by replenishing the lubricating oil;
[0033] The working principle of the utility model is as follows: when the vehicle is traveling, the electronic level 508 in the limiting mechanism 5 monitors the vehicle posture in real time. When a change in the uphill angle is detected, the gas rod body 502 is triggered to contract through the electric control box 505, driving the limit block 503 to withdraw from the top layer of the counterweight slide 403. At this time, the counterweight block 404 of the power compensation mechanism 4 moves down along the counterweight slide 403 under the action of gravity, and the connecting block 408 is pulled by the connecting wire 405 to drive the pedal body 3 to move slightly downward. The downward pulling force is accurately calculated to reach 3 kg (based on the accelerator pedal 2.0 ± 0.5 kg). Jinli standard design), transmits linear oil replenishment instructions to the engine through the pedal transmission component 2; the oil replenishment pipeline 407 is used to inject lubricating oil into the counterweight slide 403 at a later stage to ensure that the counterweight block 404 slides smoothly. When the slope disappears, the electronic level 508 triggers the gas rod body 502 to reset, and the limit block 503 returns to the top layer of the counterweight slide 403, restraining the counterweight block 404 from returning to its position. The backup battery 506 of the limiting mechanism 5 ensures the emergency response when the electronic control system is powered off, and the ventilation groove 507 maintains the heat dissipation balance inside the installation groove 504, forming a complete closed-loop control system.
