Automotive brake away system {BREAK AWAY SYSTEM FOR VEHICLE}

The present invention relates to a vehicle brake away system, and more particularly, to a vehicle brake away system capable of improving productivity and quality while being configured in a relatively simple configuration.

Generally, a braking device is configured to decelerate or stop a vehicle or maintain a certain position. Such a braking device is largely a component for generating a force required for braking by a driver, such as a brake pedal, and by this force, a hydraulic element (for example, a master bag) or a mechanical configuration (for example, a drum) is used. It consists of a component for obtaining a stopping force through, and an auxiliary device used for the purpose of braking transmission between these components.

Among these, the brake pedal, which is braked by the driver, is mounted inside the vehicle and repeatedly used so that no accident occurs by the driver. However, such brake pedal may cause injury to the driver's leg when the dash panel is deformed into the interior while the engine is pushed backward due to an accident such as a frontal collision of the vehicle.

Thus, even if the dash panel is pushed into the interior due to a crash accident, the brake away system is provided to separate the brake pedal from the dash panel by the collision load to prevent injury to the driver.

Patent document 1 relates to a brake away system for a vehicle disclosed in Korean Patent No. 10-0298053, and the collision load does not act on the pedal arm through the resonance action. When the vehicle brake away system of the patent document 1 detects the front collision of the vehicle by the collision detection mechanism 27, the pedal arm (a) is connected to the push rod lever 15 connecting the push rod 14 of the master bag 13. The clutch mechanism 18 which integrally connects 2) is separated. Therefore, even if the push rod 14 is moved rearward together with the master bag 13, the push rod lever 14 makes a resonant operation in which it is idle, so that a collision load is applied to the pedal arm 2. It will not work. Accordingly, by preventing the collision load from acting on the pedal arm through the push rod of the master bag during the front collision of the vehicle, the stepped position of the brake pedal is displaced rearward, thereby preventing the occurrence of discomfort.

The vehicle brake pedal device includes a pedal bracket having a pivot shaft, a pivot bracket having a pedal shaft, a pedal arm, a slide plate fixed between the body structural member and the pedal bracket, a shock absorbing portion, and a rotational movement. Auxiliaries are provided. The shock absorbing is such that when the pedal bracket receives an external force directed to the rear of the vehicle to a level exceeding a predetermined load, the pivot bracket is disengaged from the slide plate, so that the pivot bracket rotates about the pivot shaft, Allows the relative movement of the pivot bracket and the body structural member in the longitudinal direction of the vehicle to rotate the pedal shaft rearward. With this structure, the pressurizable position of the brake pedal can be generally in a position comfortable to the driver, which effectively avoids the discomfort imposed on the driver.

Patent document 3 relates to a vehicle brake away system disclosed in Korean Patent Registration No. 10-0852428. The vehicle brake away system relates to a vehicle brake away system, the front end of which is attached to a dash panel and has an opening surrounded by an upper fastening surface and a side fastening surface on both sides at a rear end thereof, and a tube bearing in the opening. A brace provided with a shaft coupled with the shaft, the both ends of which are fixed to the side fastening surface; A brake pedal arm assay provided with a pedal arm having an upper end thereof rotatably fixed to the tube bearing; And an upper mount bracket having a part of the front end inserted into the opening of the brace and fixed to the instrument panel of the driver's seat, the guide hole penetrating up and down on the upper surface of the upper mount bracket, the guide being bolted.
