Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly to a brake and accelerator control system. Background Art

[0002] Traditional automobile brakes and accelerators respectively adopt two independent pedals. When it is necessary to switch from the accelerator to the brake, the right foot must first be lifted to release the accelerator, then the right foot is moved to the brake pedal, and finally the brake pedal is depressed. All kinds of automobiles have an accelerator pedal and a brake pedal. If the accelerator is mistakenly depressed as the brake, it is very easy to cause traffic accidents. Most novices who have just obtained a motor vehicle driver's license are relatively unfamiliar with vehicle control. Sometimes they don't know whether their feet are on the accelerator or the brake, and they don't even know if they have stepped on the wrong pedal. In case of emergencies, their eyes and hands are often too tense, dispersing most of their energy. Coupled with the dull feeling in their feet, it is easy to step on the wrong accelerator and brake. The media often reports cases of traffic accidents caused by stepping on the accelerator as the brake. In addition to novices on the road being prone to such accidents, people who are fatigued while driving, driving under the influence of alcohol, or absent-minded are also likely to step on the wrong accelerator and brake, causing traffic accidents. Since automatic transmission vehicles do not have the control of a clutch, mistakenly stepping on the accelerator as the brake is more likely to cause a tragedy of vehicle damage and human death.

[0003] There is a need for a safer brake and accelerator control system that can solve the above problems. Summary of the Invention

[0004] The present invention provides a brake and accelerator control system, which solves the problem of the weak safety of the existing brake system by technically transforming the existing brake system.

[0005] To solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0006] A brake and accelerator control system includes a brake lever, a lever assembly, a brake module, a first rotation adjustment mechanism, a lower mounting bracket, a pin, a foot pedal, and an electronic throttle module. The brake lever is hinged and installed in the vehicle body through the lever assembly, and the brake lever can rotate around the lever assembly. A brake module is arranged at the lower end position of the lever assembly. When the brake lever rotates downward around the lever assembly, it can press down the brake module to activate the brake. The lower end of the brake lever is connected to the lower mounting bracket through the first rotation adjustment mechanism, and the first rotation adjustment mechanism can adjust the angle of the lower mounting bracket. A pin is installed at the lower end of the lower mounting bracket, and the foot pedal is sleeved on the pin through a torsion spring and the foot pedal can rotate around the pin by a certain angle. An electronic throttle module is also arranged on the bottom surface of the foot pedal.

[0007] Preferably, the first rotation adjustment mechanism includes a first horizontal shaft, a first external gear, a first internal gear, and a first spring. The first horizontal shaft is horizontally and fixedly arranged at the lower end of the brake lever. A first external gear is fixedly arranged on the first horizontal shaft. The first internal gear is fixedly arranged at the upper end of the lower mounting frame. The first internal gear can mesh with the first external gear. The side end of the first internal gear is also connected to the first horizontal shaft through the first spring. The first spring can tighten and lock the first internal gear at the first external gear.

[0008] Preferably, an electronic automatic braking system is further arranged at the upper end of the brake lever. The electronic braking control system includes a control system, a push rod structure, and a collision sensor. The collision sensor is arranged at the bumper and corresponding positions. The collision sensor is electrically connected to the control system. The push rod structure is installed at the upper end position of the lever assembly. The push rod structure can push the brake lever downward to activate the brake module to start braking under the control of the control system.

[0009] Preferably, a pressure switch is further arranged at the upper end of the brake lever. Brake lights are arranged at the front and rear ends of the vehicle. The pressure switch is electrically connected to the control system and the brake lights. The control system is also electrically connected to the electronic throttle module. When the brake lever touches the pressure switch, the circuit of the brake lights is broken, and the circuit of the electronic throttle module is connected. When the brake lever separates from the pressure switch, the circuit of the brake lights is connected, and the circuit of the electronic throttle module is broken.

[0010] Preferably, the electronic throttle module includes a throttle controller and an adjusting rod. The throttle controller is installed on the bottom surface of the foot pedal. The adjusting rod is fixedly arranged at the lower mounting frame. The lower mounting frame is arranged opposite to the throttle controller. When the foot pedal rotates around the pivot pin, the adjusting rod can push the throttle controller to increase the fuel supply and speed up.

[0011] Preferably, a second rotation adjustment mechanism is further arranged between the pivot pin and the lower mounting frame. The second rotation adjustment mechanism includes a second external gear, a second internal gear, and a second spring. The second external gear is fixedly arranged at one end of the pivot pin. The second internal gear is fixedly arranged at the lower end of the lower mounting frame. The second external gear can mesh with the second internal gear. The side end of the second internal gear is also connected to the pivot pin through the second spring. The second spring can tighten and lock the second internal gear at the second external gear.

[0012] Preferably, a chute is formed on the upper surface of the foot pedal. An upper panel is further arranged above the foot pedal. The upper panel can slide up and down on the bottom plate for adjustment. An auxiliary baffle for blocking the heel is arranged on the upper surface of the upper panel.

[0013] Preferably, the lower mounting frame includes an upper rod and a lower hanging frame part. The upper rod is connected to the brake lever through the first rotation adjustment mechanism. The pivot pin is installed between the lower hanging frame parts.

[0014] Preferably, the lower mounting bracket can also be a lower rod, the upper edge of the lower rod is connected to the brake rod through a first rotation adjustment mechanism, and the lower edge of the lower rod is connected to a shaft pin.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the vehicle has an emergency collision, the collision sensor on the bumper is turned on, and the electronic brake system is activated to quickly push the brake rod to the braking point (electric, hydraulic cylinder, pneumatic cylinder, etc. are all acceptable), with stronger safety.

[0017] Brake light switch: When the brake is lightly stepped on and the brake rod leaves the pressure switch, the brake light is on. When not stepping on the brake, when the brake switch is pressed, the brake light is open circuit and the brake light is off. When the brake light is on, the pressure switch can disconnect the fuel supply circuit through the control system. At this time, no matter how the foot pedal is stepped on, the vehicle will not move, avoiding the simultaneous activation of the brake and the accelerator.

[0018] The brake rod and the lower mounting bracket are connected and installed through a first rotation adjustment mechanism. The first rotation adjustment mechanism can adjust the angle of the lower mounting bracket, facilitating people with different leg lengths to adjust and use, and the design is more user-friendly.

[0019] The shaft pin between the lower mounting bracket and the foot pedal is also connected and installed through a second rotation adjustment mechanism. The second rotation adjustment mechanism can adjust the angle of the foot pedal (adjustable within a certain range), facilitating the angle habits of different people when stepping on the accelerator.

[0020] An electronic throttle module is installed behind the foot pedal. The foot pedal is rotatably sleeved on the shaft pin through a torsion spring. The adjustment rod of the electronic throttle module is fixedly installed at the shaft pin. When stepping down, the throttle controller approaches the adjustment rod to control the throttle controller to accelerate. When the foot pedal rotates around the shaft pin, the shaft pin remains stationary.

[0021] The upper panel of the foot pedal can be adjusted up and down, facilitating people with different foot sizes to use.

[0022] Using the foot to pedal the foot pedal drives the brake rod to move forward, then brakes, and at this time the brake light is on. When not pedaling the foot pedal and stepping on the foot pedal to rotate around the shaft pin, it can accelerate through the electronic throttle. A single foot pedal realizes the control of the brake and the throttle through different actions, which is convenient to use and has stronger safety. BRIEF DESCRIPTION OF THE DRAWINGS

As Figure 5 shown.

[0040] The first rotation adjustment mechanism and the second rotation adjustment mechanism of the present invention are not limited to the adjustment form using springs and gear sets, and other rotation adjustment structures can also be used.

[0041] The foot pedal is located at 3 / 4 of the upper end of the axle pin and 1 / 4 of the lower end, which is convenient for stepping on.

[0042] The present invention has the following characteristics:

[0043] When the vehicle has an emergency collision, the collision sensor on the bumper is turned on, and the electronic brake system is activated to quickly push the brake lever to the braking point (electric, hydraulic cylinder, pneumatic cylinder, etc. are all acceptable), with stronger safety.

[0044] Brake light switch: When the brake is lightly stepped on and the brake lever leaves the pressure switch, the brake light is on. When not stepped on and the brake switch is pressed, the brake light is open circuit and the brake light is off. When the brake light is on, the pressure switch can disconnect the fuel supply circuit through the control system. At this time, no matter how the foot pedal is stepped on, the vehicle will not move, avoiding the simultaneous activation of the brake and the accelerator.

[0045] The brake lever and the lower mounting bracket are connected and installed through a first rotation adjustment mechanism. The first rotation adjustment mechanism can adjust the angle of the lower mounting bracket, which is convenient for people with different leg lengths to adjust and use, and the design is more user-friendly.

[0046] The axle pin between the lower mounting bracket and the foot pedal is also connected and installed through a second rotation adjustment mechanism. The second rotation adjustment mechanism can adjust the angle of the foot pedal (adjustable within a certain range), which is convenient for different people's angle habits when stepping on the accelerator.

[0047] An electronic throttle module is installed behind the foot pedal. The foot pedal is rotatably sleeved on the axle pin through a torsion spring. The adjustment rod of the electronic throttle module is fixedly installed at the lower mounting bracket. When stepping down, the throttle controller approaches the adjustment rod to control the throttle controller to accelerate. When the foot pedal rotates around the axle pin, the axle pin remains stationary.

[0048] The upper panel of the foot pedal can be adjusted up and down, which is convenient for people with different foot sizes to use.

[0049] When pedaling the foot pedal to drive the brake lever to move forward, it brakes, and at this time the brake light is on. When not pedaling the foot pedal and stepping on the foot pedal to rotate around the axle pin, it can accelerate through the electronic throttle. The single foot pedal realizes the control of the brake and the throttle through different actions, which is convenient to use and has stronger safety.
