DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 4 As shown, a mechanical automobile accelerator anti-misstepping safety auxiliary device comprises a vehicle body connecting plate 1, on which an accelerator pedal rotating rod 2 is movably provided, and the accelerator pedal rotating rod 2 can rotate relative to the vehicle body connecting plate 1, one end of the accelerator pedal rotating rod 2 is connected to an accelerator pedal body 3, and the other end is connected to a vehicle acceleration component, when a user steps on the accelerator pedal body 3 with his foot, the accelerator pedal rotating rod 2 rotates downward to perform acceleration feedback;

[0027] A clamping block 5 is provided on the vehicle body connecting plate 1. There are two clamping blocks 5, which are distributed on both sides of the accelerator pedal rotating rod 2. A plurality of slots 8 are longitudinally opened on the clamping block 5. A strip slide groove 9 is horizontally opened on the vehicle body connecting plate 1. The two clamping blocks 5 are slidably connected to the strip slide groove 9. An electric telescopic rod 6 is vertically connected to the vehicle body connecting plate 1. The top of the electric telescopic rod 6 is a telescopic end, and the two sides of the telescopic end are respectively movably connected with linkage rods 7 through hinges. The ends of the linkage rods 7 are movably connected to the corresponding clamping blocks 5 through hinges. When the electric telescopic rod 6 is retracted, the telescopic end of the electric telescopic rod 6 pulls the linkage rods 7 on both sides, so that the linkage rod 7 drives the clamping blocks 5 on both sides of the accelerator pedal rotating rod 2 to slide closer to the middle along the strip slide groove 9, so that the two clamping blocks 5 clamp the accelerator pedal rotating rod 2 to prevent it from rotating.

[0028] The two clamps 5 are adjusted to have a good spacing with the accelerator pedal rotating rod 2 according to the running speed of the electric telescopic rod 6. At the same time, an electric telescopic rod 6 capable of high-speed operation is selected, and the model is TYSC065. When it is necessary to prevent the accelerator from being stepped on, the electric telescopic rod 6 is quickly retracted, so that the two clamps 5 quickly clamp the accelerator pedal rotating rod 2.

[0029] The accelerator pedal body 3 is provided with a pressure sensing switch 12 electrically connected to the electric telescopic rod 6. The circuit between the pressure sensing switch 12 and the electric telescopic rod 6 is connected with a circuit breaker key switch 4. The circuit breaker key switch 4 can be installed in a position in the car that is convenient for the driver to operate. When the driver needs to step on the accelerator to accelerate, the circuit breaker key switch 4 can be pressed to disconnect the circuit between the pressure sensing switch 12 and the electric telescopic rod 6 to avoid affecting the acceleration. The pressure sensing switch 12 is also connected to the automobile CPU processor. When the driver encounters an emergency and needs to brake suddenly, the accelerator is pressed due to tension. The door pedal body 3 is stepped on hard as a brake. At this time, the pressure sensing switch 12 on the accelerator pedal body 3 is subjected to an instantaneous impact force exceeding the set value, and the pressure sensing switch 12 generates feedback, causing the electric telescopic rod 6 to contract. In this way, the electric telescopic rod 6 pulls the clamping blocks 5 distributed on both sides of the accelerator pedal rotating rod 2 through the linkage rod 7 to slide together quickly, thereby fixing the accelerator pedal rotating rod 2 to prevent the throttle from increasing instantly. At the same time, the automobile CPU processor compares the value of the pressure sensing switch 12 with the preset value to determine whether it is an emergency brake signal. If so, the automobile brakes;

[0030] The clamp block 5, the electric telescopic rod 6 and other moving components have no direct contact with the accelerator pedal rotating rod 2 and the accelerator pedal body 3 under normal conditions, so interference can be avoided, and some mechanical components can be prevented from getting stuck over time, resulting in the accelerator pedal body 3 being unable to be stepped on;

[0031] A mounting groove 10 is provided on the accelerator pedal body 3, and a pressure sensing switch 12 is fixedly installed in the mounting groove 10. A pressure plate 11 covers the pressure sensing switch 12, and the pressure plate 11 cooperates with the mounting groove 10. A rubber ring 13 is connected between the pressure plate 11 and the inner wall of the mounting groove 10, and the rubber ring 13 can be stretched and deformed. An anti-skid groove 14 is provided on the pressure plate 11. The pressure plate 11 covers the pressure sensing switch 12 to prevent it from being directly stepped on by the driver's feet and easily adhered to dirt. At the same time, when the pressure plate 11 is stepped on, since the pressure plate 11 is connected to the mounting groove 10 through the rubber ring 13, the rubber ring 13 can be stretched when the pressure plate 11 is subjected to a large impact force, so that the pressure plate 11 acts on the pressure sensing switch 12 conveniently, and the anti-skid grooves 14 distributed on the pressure plate 11 prevent the foot from slipping on it.

[0032] The working principle of the utility model is as follows: when the driver needs to brake suddenly in an emergency, due to nervousness, the accelerator pedal body 3 is stepped on as a brake, and the pressure plate 11 on the accelerator pedal body 3 is subjected to a large impact force, and the impact force is transmitted to the pressure sensing switch 12, and then the pressure sensing switch 12 is subjected to an instantaneous impact force exceeding a set value, and the pressure sensing switch 12 generates feedback, so that the electric telescopic rod 6 is contracted, so that the electric telescopic rod 6 pulls the clamping blocks 5 distributed on both sides of the accelerator pedal rotating rod 2 to slide together quickly through the linkage rod 7, thereby fixing and clamping the accelerator pedal rotating rod 2 to avoid the throttle being increased instantly and causing a dangerous accident. At the same time, the automobile CPU processor compares the value of the pressure sensing switch 12 with the preset value to determine whether it is an emergency brake signal. If so, the automobile brakes;

[0033] When the driver needs to step on the accelerator to accelerate under special circumstances, he can press the circuit breaker button switch 4 to disconnect the circuit between the pressure sensing switch 12 and the electric telescopic rod 6 to avoid feedback and affect acceleration;

[0034] Furthermore, the clamp block 5, the electric telescopic rod 6 and other moving components have no direct contact with the accelerator pedal rotating rod 2 and the accelerator pedal body 3 under normal conditions, thereby avoiding interference and preventing some mechanical components from getting stuck over time, resulting in the accelerator pedal body 3 being unable to be stepped on.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
