An improved unmanned formula car brake mechanism

Abstract

The invention discloses an improved unmanned formula car brake mechanism comprising a bottom plate, sliding rails installed on the bottom plate, a push rod, a brake plate, a hinged support plate, a pin, a connecting rod, a rocker, a motor, a controller, a pressure sensor, a brake pedal, a brake pedal arm, pulleys, a first return spring for rail reset and a second return spring for brake plate reset. The mechanism of the invention is advantaged in that: 1, the design adopts a rigid rod with large bearing capacity, small deflection and high reliability to replace a steel wire rope; 2, a motor main shaft and a rocker are connected by a spline shaft, and the forward rotation of the motor directly drives the rocker to rotate, thereby driving the connecting rod to perform translational movementso as to drive the brake plate arm to rotate for a corresponding angle, which compensates for the defects of unsatisfactory response and inaccurate trajectories in conventional winders; and 3, four pulleys are added to the bottom of the slide rails to cooperate with two sliding grooves in the frame to enable movement, thus solving the problem of mechanism offset due that mechanisms are not compact.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to an improved driverless formula car braking mechanism. Background technique [0002] Today, the development of intelligent control and interconnection technology is changing rapidly, and unmanned driving has also emerged in this environment. In order to promote the development of talents in my country's auto industry, colleges and universities encourage students to refit the original gasoline racing cars into electric racing cars, research driverless technology, and participate in the Chinese College Student Formula Electric Car Competition (FSEC). According to the requirements of the competition, the racing car should realize driverless driving on the basis that the driver can drive safely. Among them, the control-by-wire modification of the braking system is a particularly important part. [0003] In order to solve the above problems, the author Fu Yunfei and others on...

AI Technical Summary

Problems solved by technology

However, in the process of practical application, it is found that this solution still has the following deficiencies: 1) The steel wire rope has poor reliability, which is inherently unsafe and unstable; 2) The elastic deformation of the steel wire rope and the winding deviation of the winder easily lead to braking The response is not timely; 3) The mechanism is not compact, and the movement track of the mechanism is prone to deviation during the braking process
