Regarding the working principle of the electric control jumper bar type brake system of the automobile, taking the positive button to trigger the brake control as an example, the working principle can be understood as follows:

1) brake control

When a driver presses a positive button 16-1 on a steering wheel, the positive button 16-1 triggers the first electromagnetic valve 15 and the second electromagnetic valve 55 to perform corresponding actions, the second electromagnetic valve 55 pushes a rack 57 to move outwards, and the first electromagnetic valve 15 pushes the holder 17 to move towards the direction of the tray 43, so that the holder 17 is connected with the tray 43, thereby closing the clutch balls 45, and then the holder 17 pushes the second connecting rod 40 to move towards the direction of the driving mechanism 2 through the tray 43, so that the first clutch rubber block 39 is in sealing connection with the second clutch rubber block 42, thereby realizing the movable connection between the first connecting rod 37 and the second connecting rod 40, while the second connecting rod 40 moves, the mounting flange 47 on the second connecting rod 40 moves along with the second connecting rod 40, thereby compressing the second return spring 46;

after the first clutch rubber block 39 and the second clutch rubber block 42 are hermetically connected, the transmission shaft 34 driven by the motor to rotate axially drives the first connecting rod 37 to rotate axially through the driving gear 35 and the driven gear 38, the first connecting rod 37 drives the second connecting rod 40 to axially rotate through the first clutch rubber block 39 and the second clutch rubber block 42, thereby driving the first gear 48 fixedly connected to the second link 40 to rotate, and at this time, although the holder 17 is connected to the tray 43, since the engaging and disengaging balls are installed in the tray 43, the second connecting rod 40 transmits the acting force which rotates axially to the clutch ball 45 through the tray 43, and the clutch ball 45 consumes and counteracts the acting force by performing non-directional autorotation, so that the holder 17 cannot rotate axially along with the tray 43;

the first gear 48 drives the rack 50 engaged with the first gear to move backwards until the first gear 48 is separated from the rack 50, and during the process that the rack 50 moves backwards, the third return spring 56 is pulled open by the connecting convex nail 58, the second gear 53 is also pushed to rotate, and the spool 52 is pushed to rotate by the second gear 53, so that the spool 52 can pull and tighten the brake cable 12 by rotating, thereby pulling down the brake rod 4, so that the brake rubber block 11 is in friction contact with the ground, thereby realizing the braking of the automobile, and during the braking, the inertia acting force of the automobile is transmitted to the first buffer mechanism 5 through the bottom beam 6, and is consumed by the first buffer mechanism 5, thereby reducing the impact of the acting force inertia of the automobile on the brake rod 4, while the brake rod 4 is pulled down, the first return spring 14 is pulled to be opened through the return steel wire rope 13;

after the rack 50 is separated from the first gear 48, the rack still continues to move backwards under the influence of self inertia until one end of the rack 50 abuts against the abutting screw 54 to be in toothed connection, and at the moment, the rack 57 connected with the second electromagnetic valve 55 is just in toothed connection with the rack 50, so that the rack 50 is clamped, and the rack 50 is prevented from moving reversely.

2) Brake release

The driver presses the negative button 16-2 to trigger the second electromagnetic valve 55 to perform a corresponding action, and pulls the rack 57 back, so that the rack 57 is separated from the rack 50 and reset, and triggers the first electromagnetic valve 15 to release the holder 17, because the external thrust applied to the holder 17 disappears, the thrust applied to the second connecting rod 40 by the holder 17 also disappears, at this time, the originally compressed second reset spring 46 is released by itself to restore the original shape, and in the process of relaxation, the mounting flange 47 drives the second connecting rod 40 to move towards the direction of the first electromagnetic valve 15, so that the second clutch rubber 42 is separated from the first clutch rubber 39, and pushes the holder 17 to move towards the first electromagnetic valve 15, and when the second reset spring 46 restores the original shape and stops deforming, the second connecting rod 40 also stops moving along with the second connecting rod, and the supporting arm 17 pushed by the tray 43 continues moving under the influence of the inertia of the second connecting rod, so that the second connecting rod is separated from the tray 43 and is reset;

after the rack 50 is separated from the rack bar 57, at this time, the rack 50 is in a free state, the third return spring 56, which is originally pulled open, automatically contracts to restore the original shape, and the connecting stud 58 drives the rack 50 to move toward the direction of the first gear 48; the rack 50 pushes the spool 52 to rotate through the second gear 53 while moving, so that the brake cable 12 is in a release state, and thus, the pulling force of the brake cable 12 on the brake lever 4 disappears, and the first return spring 14, which is originally released, contracts by itself, and pulls the brake lever 4 to return through the return cable 13.

It is to be understood that the foregoing examples, while indicating the preferred embodiments of the utility model, are given by way of illustration and description, and are not to be construed as limiting the scope of the utility model; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several changes and modifications can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all equivalent changes and modifications made within the spirit and scope of the present invention should be covered by the appended claims.
