Abstract

An ergonomics optimization-based parking brake control system comprises a handle assembly (7) and a pull rope (3) connected to a brake system. A hand brake plate (2) is provided at one side of the handle assembly (7) close to the body of a driver. One end of the hand brake plate (2) is rotatably connected to a handle portion (72) by means of a rotary shaft (75). One end of the pull rope (3) is connected to the hand brake plate (2) at a position away from the rotary shaft (75). In contrast to existing parking brake switches that are turned on or off by pulling a brake lever located beside the driver's foot up or down, the present invention employs eccentric rotation of the pull rope at the hand brake plate so as to drive the pull rope to move. The hand brake plate in an unlocked state is arranged at the handle assembly, and such utilization of the space at the handle assembly provides an evident indication to the driver. Since the handle assembly is provided at a position in which the driver inserts or removes a key, the hand brake plate is easily visible to the driver, thereby reducing the likelihood that a driver will forget to perform a parking brake operation before getting out of a car.

Example three:

The difference between Embodiment 3 and Embodiment 2 is that, as shown in FIG. 11, a pull cord 82 is fixed between the outer wall of the handbrake 2 and the stop 78, and the stop 78 can move back and forth in the direction of the rotating shaft 75.

As shown in FIGS. 12 and 13, a slide 81 is provided in the convex block of the connecting block 74, and a long insulating sheet 8 is fixed on the upper end of the stopper 78. The insulating sheet 8 moves inside the slide 81 and blocks The block 78 moves under the slideway 81; the inner wall of the slideway 81 is provided with a concave slide slot 91, and a slider 92 sliding along the slide slot 91 is fixed on the insulating sheet 8; due to the slide slot 91 and the slide slot 91 In the vertical partition relationship of the inner wall, the insulating sheet 8 will not directly slide off the slideway 81 vertically. Therefore, the insulating sheet 8 can move freely in the slideway 81 when the stopper 78 drives back and forth.

A circular hole is opened on the side wall of the slideway 81, and a starting wire 83 is placed in the round hole, the starting wire 83 is cut off at the position of the slideway 81, and both ends of the cutoff position are provided with the elasticity of the same structure as described below switch:

The elastic switch is: the end of the starting wire 83 is fixed with an elastic member 85, and the elastic member 85 is a spring. The circular hole is fixed with a plunger. The plunger is inserted into the spring laterally to fix the spring in the circular hole, and the other end of the spring is fixed with a metal sheet 84; under the elastic force of the spring, the two metal sheets 84 at the position where the wire 83 is cut off are activated Fit each other and have a tendency to move toward each other.

When the insulating sheet 8 is moved between the two metal sheets 84, the two metal sheets 84 will be separated, so that the starting wire 83 is disconnected.

The working principle is explained. When parking is required, when the handbrake plate 22 rotates clockwise as shown in FIG. 5, the short side of the handbrake plate 2 will hit the stopper 78. At this time, the stopper 78 is pushed toward the two by the pusher The metal sheet 84 moves in the direction so that the insulating sheet 8 is inserted between the two metal sheets 84 to realize the disconnection of the starting wire 83, that is, the completion of the parking operation and the disconnection of the starting power supply of the vehicle body.

When you need to drive, turn the handbrake 2 counterclockwise. At this time, the pull cord 82 pulls the push block to move, so that the insulating sheet 8 is separated from the two metal sheets 84, and the wire 83 is activated to achieve the path. Start action. The two handbrake plates 2 each control the passage of the starting wire 83 for a period of time. This design makes it difficult to start the car body before the car body is cancelled and reduce the damage of the car body.
