Problems solved by technology

The existing accelerator pedal and brake pedal linkage devices are mainly solenoid valve control type and lever control type. The solenoid valve control type uses more electrical components, consumes a lot of power, and absorbs the force of the brake pedal when the accelerator is stepped on by mistake. Very large, it is difficult to realize the brake linkage action, and the reliability is poor; the lever control type is large in size, inconvenient to arrange and install in the car, not only the cost is high, but also easy to interfere with peripheral parts, the reliability is not guaranteed

Embodiment 1

[0030] Such as figure 1 As shown, the brake pedal 1 is located on the left side of the accelerator pedal 2, and a brake linkage plate 7 is arranged on the right side of the brake pedal 1. The brake linkage plate 7 is in a "Z" shape with a high left end and a low right end. The top surface fits with the bottom surface of the brake pedal 1 and is fixed by vertical bolts. The holes for the vertical bolts to pass through on the brake linkage plate 7 are elongated holes extending horizontally. By changing the position of the vertical bolt in the elongated hole, the lateral position of the brake linkage plate 7 can be changed.

[0031] Such as figure 1 As shown, an accelerator linkage plate 3 is provided on the left side of the accelerator pedal 2. The accelerator linkage plate 3 is in the shape of a “Z” with a high left end and a low right end. The right end of the accelerator linkage plate 3 is connected to the accelerator pedal 2 through horizontal bolts, and the accelerator lin...

Embodiment 2

[0041] Such as figure 2 , image 3 As shown, the present embodiment does not have an accelerator linkage plate, and the accelerator limit warning switch 8 is installed on the accelerator warning switch bracket 8 ', and the contact of the accelerator limit warning switch 8 is close to the corner of the front part of the accelerator pedal 2 connecting rods. The throttle alarm switch bracket 8' is installed on the cab base plate or the throttle controller base, the throttle alarm switch bracket 8' can be connected with the cab base plate or the throttle controller base through a torsion spring, and the throttle alarm switch bracket 8' can also be formed by Spring steel sheets are bent.

[0042] Such as figure 2 , image 3As shown, the engine flameout switch 10 is installed on the transverse section of the "L" shaped brake linkage plate 7, and the contact of the engine flameout switch 10 is higher than the top surface of the brake linkage plate 7 transverse sections. Also ha...

Embodiment 3

[0050] Such as Figure 4 as shown,

[0051] In the present embodiment, the accelerator limit warning switch 8 is installed on the bottom of the rotating link plate 13, which is inclined to be high at the front and low at the rear. The upper end of the rotating link plate 13 is hinged with the top of the brake link plate 7 by rotating the positioning pin shaft 14, and a torsion spring 15 is set on the rotating positioning pin shaft 14. Another leg of spring 15 is connected with brake linkage plate 7. Described brake linkage plate 7 is fan-shaped, and the top of brake linkage plate 7 is fixed with brake pedal 1, and engine flameout switch 10 is installed at the lower end of brake linkage plate 7, and is provided with and rotates linkage plate 13 next to engine flameout switch 10 Matching force-bearing boss 7b. A plurality of limit holes are arranged at the lower end of the brake linkage plate 7 close to the arc edge, and a throttle maximum position adjustment pin 16 is insert...

Abstract

The invention discloses a safety protection device for preventing from mistakenly stepping on an accelerator of a car. According to the safety protection device, an accelerator limit early-warning switch (8) and an engine stalling switch (10) are arranged in a rotating range of an accelerator pedal (2); the accelerator limit early-warning switch (8) is connected with an accelerator limit warning lamp or a voice prompter (9) by a lead wire; the engine stalling switch (10) is mounted on a brake linkage plate (7) and is connected with an engine stalling relay (11) by a lead wire; the engine stalling relay (11) is connected into a control circuit of an engine in series. According to the safety protection device for preventing from mistakenly stepping on the accelerator of the car, a caution and reminding effect is realized when a pre-set speed is exceeded under the precondition of not influencing the normal manipulation of the car, and then a driver can lower the car speed in time; when the driver violently steps on the accelerator pedal by mistake, the safety protection device can timely control the engine to be stalled and emergently brake for stopping the car, so that major traffic accidents or casualty accidents are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of motor vehicles, and in particular relates to a safety protection device for accidentally stepping on the gas pedal of an automobile. Background technique [0002] The operation control device of accelerator and brake is the most important safety control device in auto parts. For novices who are just learning how to drive a car, because they are extremely unskilled in the coordinated operation and control of the accelerator pedal and the brake pedal, what beginners are most afraid of is accidentally stepping on the accelerator pedal as a brake, which will cause safety accidents; When the driver is nervous or tired and encounters abnormal situations such as emergency emergencies, he can't guarantee that the accelerator pedal will not be accidentally stepped on as a brake. According to the statistics of the transportation department, a large number of such accidents occur every year in the country. Drivers ...
