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

Embodiment 1

[0030] Such as Figure 1 to Figure 5 As shown, this embodiment discloses an improved driverless formula car brake mechanism, which mainly includes a base plate, a slide rail 1 installed on the base plate, a push rod 2, a brake plate 5, a hinge Plate 6, pin 7, connecting rod 8, rocker 9, motor 11, controller 13, pressure sensor 14, brake pedal, brake pedal arm, pulley 22, first return spring 17 for slide rail 1 reset and The second return spring 18 for the return of the brake plate 5.

[0031]Specifically, the bottom plate is fixedly installed on the vehicle frame 23 through bolts 24, or is designed integrally with the vehicle frame 23; the slide rail 1 is arranged on the bottom plate, and pulleys 22 are installed on both sides thereof. The bottom plate is provided with chute 21 on both sides of the slide rail 1 , and the pulley 22 is embedded in the chute 21 to realize the sliding of the slide rail 1 on the chute 21 . One end of the push rod 2 is hinged to one end of the bra...

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...
