Automobile accelerator pedal assembly preventing mistaken pressing

Abstract

The invention provides an automobile accelerator pedal assembly preventing mistaken pressing and belongs to the technical field of automobile parts. The upper end of an auxiliary rod is hinged with afoundation column through a sleeve and the lower end of the auxiliary rod is hinged with a linkage mechanism through a second shaft pin; a linkage part is arranged at the middle of the auxiliary rod;one end of the linkage part is fixed to the inner side of the auxiliary rod and a clamping groove at the other end of the linkage part is matched with a brake rod; a base shaft equipped with a first roller is longitudinally arranged at the bottom of a base of an accelerator pedal; the linkage mechanism is arranged at the front end of the plane of the base; a linkage mechanism bracket comprises twosymmetrical vertical side plates provided with through grooves; the bottom of the linkage mechanism bracket is fixed to the base; a second roller is arranged at the middle of the second shaft pin; both ends of the second shaft pin are matched with the through grooves; the second shaft pin runs through the through grooves and is hinged with the auxiliary rod; a displacement sensor is arranged at the middle of the back of the accelerator pedal; a guide rod seat is arranged at the upper part of the back of the accelerator pedal; one end of a guide rod is matched with the guide rod seat and the other end of the guide rod is provided with a guide wheel matched with a groove channel; and the side wall, on the right side of the accelerator pedal, of the automobile is provided with a position-limiting mechanism. The automobile accelerator pedal assembly preventing the mistaken pressing is mainly used for automobile active safety.

Description

technical field [0001] The invention belongs to the technical field of auto parts. Background technique [0002] The research on anti-accelerator pedal misoperation is to avoid accidents caused by the driver's misoperation of the accelerator pedal, that is, stepping on the accelerator by mistake, which is of great significance to road traffic safety. During the driving process of the car, the driver needs to switch frequently between the accelerator pedal and the brake pedal, the feet are prone to fatigue, and it is easy to confuse the accelerator pedal and the brake pedal. During the driving process, the driver missteps the accelerator pedal as the brake pedal due to fatigue, nervousness, lack of concentration, etc., causing serious traffic accidents from time to time. Novice drivers who have not developed driving habits are more likely to make mistakes. Generally, when the driver is about to take emergency braking measures, the distance between the car and the obstacle i...

Problems solved by technology

For example, the anti-misstepping accelerator device disclosed in Chinese Patent Application No. 2016108021452, the anti-misstepping accelerator device described in this patent, relies on identifying the magnitude of the stepping on the accelerator to make misoperation judgments, and can realize alarming and timely braking in case of misstepping, but A large number of sensors are installed on the accelerator pedal, the electrical components are complicated, and the system reliability is low

Another example is the automobile driver’s mistaken stepping on t
