Example 1

Please refer to fig. 1 and 2, a low noise brake pedal 1 for a new energy automobile in the figure, including pedal 1, frame 2 and vacuum booster 3, pedal 1 outer end is connected with frame 2, and frame 2 is fixed with 3 shells of vacuum booster, booster push rod 4 is inserted in vacuum booster 3, and be connected with pedal 1 through booster push rod 4, and the booster outside cover has return spring 5, still include low noise gum cover 6, the low noise gum cover 6 of cover in the return spring 5 outside is installed between pedal 1 and vacuum booster 3, booster push rod 4 is close to pedal 1 one end and is fixed with mounting panel 7 fixed mutually with low noise gum cover 6.

It should be noted that: in this scheme, footboard 1, frame 2 and vacuum booster 3 are current structure, and low noise gum cover 6 replaces current protection gum cover position to install.

In this embodiment, please refer to fig. 3 and 4, the illustrated low-noise rubber sleeve 6 includes a track ring 8 fixed on the outer side of the housing of the vacuum booster 3, a plurality of track grooves 9 are formed on the outer side of the track ring 8 at equal intervals, steering grooves 10 are communicated between the track grooves 9, a guide block 11 is fixed in the track grooves 9 at a position corresponding to the steering grooves 10, a rotating member 12 is slidably sleeved on the outer side of the track ring 8, a telescopic sleeve 13 is fixed at the outer end of the rotating member 12, a connecting table 14 fixed to the mounting plate 7 is fixed at the outer end of the telescopic sleeve 13, and a limit housing 15 for limiting the rotating member 12 is fixed on the outer side of the housing of the vacuum booster 3;

in order to facilitate subsequent movement and rotation, the guide block 11 is designed to be of a triangular structure, the inclined end of the guide block 11 is consistent with the inclination of the steering groove 10, and an inclined chamfer is formed at one end, close to the vacuum booster 3, of the guide block 11.

Referring to fig. 8 and 9, the rotating member 12 shown in the figure includes a contact ring 16 and an i-shaped ring 17, the contact ring 16 contacts with the housing of the vacuum booster 3, a plurality of connecting rods 18 inserted into the i-shaped ring 17 are fixed on the outer side of the contact ring 16, the i-shaped ring 17 abuts against the limiting housing 15, the outer end of the i-shaped ring 17 is fixed with one end of the telescopic sleeve 13, and a plurality of contact members 19 contacting with the track grooves 9 are installed in the i-shaped ring 17.

It should be noted that, when a person steps on the pedal 1, the booster push rod 4 is squeezed, and at this time, the telescopic sleeve 13 is contracted to push the i-shaped ring 17 to move inwards, so that the contact piece 19 moves a distance along the track groove 9, and then the contact piece contacts the guide block 11 to move into the steering groove 10, thereby achieving steering of the telescopic sleeve 13.

Referring to fig. 9, the contact member 19 shown in the figure includes a slide rod 20 slidably inserted into the i-shaped ring 17, a connection ball 21 contacting with the track groove 9 is fixed at the outer end of the slide rod 20, and an extrusion spring 22 abutting against the i-shaped ring 17 and the connection ball 21 is sleeved outside the slide rod 20;
