Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and particularly refers to a structure of a foot brake. Background Art

[0002] During the process of driving a vehicle, the brake pedal is an important component that reflects the driver's driving intention. The traditional brake pedal is formed by metal stamping and consists of a lever mechanism through welding and assembly. The driver steps on the brake pedal, and with the assistance of a booster, the piston in the hydraulic brake cylinder is pushed to build pressure. Under the action of hydraulic pressure, the brake realizes frictional braking at the wheel.

[0003] Under the general trend of carbon neutrality, energy conservation, emission reduction, and lightweight are major trends in vehicle development. However, the brake pedal in the prior art is made of metal structure and formed by metal stamping and welding, resulting in a relatively large weight of the entire brake pedal, being rather bulky to use, and not conforming to the lightweight trend. Content of the Utility Model

[0004] The purpose of the utility model is to provide a foot brake structure with a simple and reasonable structure, the overall weight of the brake pedal and the pedal piece being relatively light, and having good strength and toughness, which conforms to the lightweight trend.

[0005] The purpose of the utility model is achieved as follows:

[0006] A foot brake structure includes a brake swing arm and a pedal piece that are integrally formed of peek plastic material. One end of the brake swing arm is provided with a rotating cylinder for connecting to a base, the pedal piece is arranged at the other end of the brake swing arm, and the brake swing arm is further provided with a driving hole for connecting to a vacuum booster and a limit contact piece for the brake light switch push rod, and both the driving hole and the limit contact piece for the brake light switch push rod are arranged away from the pedal piece.

[0007] In the above foot brake structure, the cross-section of the brake swing arm is in a checkmark-shaped structure.

[0008] In the above foot brake structure, a first reinforcing rib is arranged on the circumferential side of the rotating cylinder.

[0009] In the above foot brake structure, a second reinforcing rib is arranged on the side of the limit contact piece for the brake light switch push rod away from the rotating cylinder.

[0010] In the above foot brake structure, third reinforcing ribs are protrudingly formed on the edges of both side surfaces of the brake swing arm.

[0011] In the above foot brake structure, fourth reinforcing ribs are arranged on both side surfaces of the brake swing arm, and the fourth reinforcing ribs are arranged in a staggered manner.

[0012] In the above-mentioned foot brake structure, the reinforcing rib four is connected to the reinforcing rib three.

[0013] The prominent and beneficial technical effects of the present utility model compared with the prior art are as follows:

[0014] The brake swing arm and the pedal piece of the present utility model are injection molded by a mold and made of PEEK plastic. Specifically, the brake pedal and the pedal piece are relatively light as a whole, and have good strength and toughness, meeting the lightweight trend. At the same time, the designed rotating cylinder is connected to the connecting base. After stepping on the pedal piece, the brake light switch push rod limit contact piece on the brake swing arm will control the brake light to light up, playing a reminder role.
