Description

Technical Field

[0001] This utility model belongs to the field of automotive brake pedals, specifically, it relates to a pedal damping structure. Background Technology

[0002] In new energy vehicles using Onebox brake-by-wire, when adjusting the brake pedal feel, to ensure good pedal force and pedal travel linearity, especially considering the initial pedal force and pedal return support, the spring force is slightly too large when selecting the Onebox simulator. This causes the pedal to impact and produce abnormal noise when returning to the initial position, resulting in a brake switch malfunction, the brake light remaining on, and the vehicle becoming inoperable. Usually, the pedal arm sleeve is interfered with, resulting in poor pedal feel linearity, or a counterweight is added to the pedal arm to reduce pedal return impact. However, both of these methods affect the pedal feel during the braking process.

[0003] To address the aforementioned issues, patent document 212890287U discloses a connection structure for a brake pedal return spring, comprising a return spring, one end of which is detachably connected to a first mounting bracket fixedly connected to the brake pedal arm, and the other end of which is detachably connected to a second mounting bracket fixedly connected to the pedal assembly bracket body; spring bushings are snapped into the mounting bracket holes of both the first and second mounting brackets, and the two ends of the return spring are respectively connected to the two spring bushings, but this does not solve the aforementioned problems.

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0022] Figure 1 This is a schematic diagram of the pedal damping structure in an embodiment of this utility model; Figure 2 This is a schematic diagram of the structure in an embodiment of the present invention, showing the damping component mounted on the pedal body.

[0023] like Figure 1 and Figure 2 As shown, the pedal damping structure provided by this utility model is installed on a car pedal. The car pedal includes a pedal body 1 and a pedal arm intermediate shaft 2 movably connected to the pedal body 1. The pedal arm intermediate shaft 2 passes through the pedal arm on the pedal body 1. During the braking process and the return process, the pedal arm intermediate shaft 2 can rotate with the pedal body 1. The pedal damping structure includes a damping component 10 and a rebound trigger structure 20. The rebound trigger structure 20 is installed on the pedal arm intermediate shaft 2, and the damping component 10 is installed on the pedal body 1, located on one side of the rebound trigger structure 20. The rebound trigger structure 20 can trigger the damping component 10 during the return process of the pedal body 1, thereby buffering the return process of the pedal body 1 and effectively reducing the return impact of the pedal body 1. The damping component 10 also improves the pedal feel of stepping on the body 1 during the braking process and avoids the problem of the brake switch and brake light remaining on due to the return impact of stepping on the body 1.

[0024] The rebound trigger structure 20 includes a sleeve 21, which is sleeved on one end of the pedal arm intermediate shaft 2. The sleeve 21 is set on the pedal arm intermediate shaft 2 by a key connection, so that the pedal arm intermediate shaft 2 can drive the sleeve 21 to rotate. The sleeve 21 is provided with a boss 22, which is located on the side of the sleeve 21 near the damping component 10. During the braking process and the return process, the pedal arm intermediate shaft 2 can drive the sleeve 21 to rotate, and the boss 22 can abut against the damping component 20, thereby buffering the return process of the pedal body 1, effectively reducing the return impact of the pedal body 1, and avoiding the problem of the brake switch and brake light remaining on due to the return impact of stepping on the pedal body 1.

[0025] Figure 3 This is a schematic diagram of the damping component in an embodiment of this utility model.

[0026] The damping assembly 10 includes a base 11, a housing 12, and a push rod 13. The base 11 is located at the bottom of the pedal body 1, on the side of the pedal body 1 near the intermediate shaft 2 of the pedal arm. The housing 12 is mounted on the base 11 and is hollow cylindrical. One end of the push rod 13 is movably disposed within the housing 12, and is adapted to fit the housing 12. The other end of the push rod 13 is telescopically disposed within the housing 12. The end of the push rod 13 away from the housing 12 abuts against the boss 22. The base 11, housing 12, and push rod 13 form a... A cavity 14 is formed, and a spring 15 is installed inside the cavity 14. One end of the spring 15 is connected to the base 11, and the other end is connected to the end of the push rod 13 located inside the housing 12. The spring 15 is in a compressed state, so that the push rod 13 can always abut against the boss 22 during the braking process and the return process, thereby buffering the return process of the pedal body 1, effectively reducing the return impact of the pedal body 1, and avoiding the problem that the brake switch and brake light will remain on due to the impact of stepping on the return of the pedal body 1. The damping component 10 also improves the pedal feel of stepping on the pedal body 1 during the braking process.

[0027] A limiting flange 121 is provided on the edge of the housing 12 away from the base 11. The limiting flange 121 is annular. A limiting protrusion 131 is provided at one end of the push rod 13 located inside the housing 12. The limiting protrusion 131 abuts against the limiting flange 121, thereby limiting the push rod 13 and preventing the push rod 13 from slipping out of the housing 12, thus improving the reliability of the structure.

[0028] The end of the push rod 13 near the boss 22 is hemispherical, which can reduce friction noise and wear when the push rod 13 abuts the boss 22 during braking and return processes, further improving the reliability of the structure and extending the service life of the damping assembly 10 and the pedal damping structure.

[0029] The side of the boss 22 closest to the push rod 13 is arc-shaped. During the braking and return processes, one end of the push rod 13 is always in contact with the arc-shaped surface of the boss 22. By simulating and analyzing the braking and return processes, the shape of the arc-shaped surface of the boss 22 can be optimized, further avoiding abruptness and nonlinearity when stepping on the pedal during the braking and return processes, and further improving the structural reliability of the pedal damping structure.

[0030] The pedal damping structure provided by this utility model is set at both ends of the pedal arm intermediate shaft 2. Both ends of the pedal arm intermediate shaft 2 are fitted with sleeves 21. Two damping components 10 are respectively set on the pedal body 1, corresponding to the positions of the two sleeves 21. This allows for further buffering of the return process of the pedal body 1, further effectively reducing the return impact of the pedal body 1, and further avoiding the problem of the brake switch and brake light remaining on due to the return impact of stepping on the pedal body 1.
