Description

Technical Field

[0001] This utility model relates to the field of brake pedal technology, specifically a car brake pedal with adjustable travel. Background Technology

[0002] The brake pedal, commonly known as the brake pedal, is the operating device of the vehicle's brake system. It is a key operating component in the vehicle's braking system, used to control the vehicle's deceleration and stopping. It is used very frequently and has a significant impact on driving safety. Brake pedals are mainly divided into two types: mechanical brake pedals and electronic brake pedals. Mechanical brake pedals control the operation of the brakes by pressing or releasing the pedal, while electronic brake pedals use electronic signals for control and are usually used in advanced driver assistance systems.

[0003] The existing brake pedal mainly consists of a pedal, a linkage, and a rubber pad. The linkage connects the pedal to the braking system and transmits the pedal travel. The existing car brake pedal cannot adjust the travel of the pedal, which affects the comfort of pedal operation. After the vehicle has been used for a long time, the travel of the brake pedal becomes longer and affects the handling of the car when braking. Utility Model Content

[0025] The mounting plate 8 has a limiting plate 14. A connecting plate 9 is vertically arranged at the bottom of the mounting plate 8. A mounting bracket 11 is arranged between the two connecting plates 9. A connecting block 16 is arranged on the mounting bracket 11. A rotating plate 17 is rotatably arranged on the connecting block 16. A positioning block 12 is arranged between the two rotating plates 17. A fixing cylinder 18 is arranged on the positioning block 12. An adjusting rod 13 is arranged inside the fixing cylinder 18. The adjusting rod 13 is fixed by a fixing screw 19. A limiting plate 14 is provided at one end of the adjusting rod 13.

[0026] An adjustment mechanism is provided on the mounting bracket 11, which can adjust the position of the positioning block 12 and the limiting plate 14.

[0027] The car brake pedal, which facilitates stroke adjustment, adjusts the distance between two sets of connecting blocks 16 through an adjustment mechanism. The adjustment block 16 drives the positioning block 12 to move via the rotating plate 17, and the positioning block 12 drives the limiting plate 14 to move, thereby adjusting the distance between the limiting plate 14 and the mounting bracket 11. When the brake pedal 3 is pressed down, the brake pedal 3 drives the pedal arm 2 to rotate downward. The pedal arm 2 stops moving after contacting the limiting plate 14, thus realizing the stroke adjustment of the brake pedal and making stroke adjustment more convenient. As an embodiment, the left, right, up, and down positions of the various components shown in the attached drawings are only one arrangement method, and the specific positions are set according to specific needs.

[0028] In one embodiment, such as Figure 1-4 As shown, the adjustment mechanism includes a fixed groove 113, a sliding groove 112, and a positioning pin 15. The mounting bracket 11 has a sliding groove 112 and a fixed groove 113. Multiple fixed grooves 113 are connected to the sliding grooves 112. The connecting block 16 is disposed inside the fixed groove 113. The connecting block 16 can move along the sliding groove 112 into different fixed grooves 113 to adjust its position. The mounting bracket 11 has a fixing pin 15 at its top. The bottom end of the fixing pin 15 contacts the connecting block 16 and can limit the position of the connecting block 16. One end of the rotating plate 17 has a rotating shaft 20. The rotating plate 17 is rotatably connected to the positioning block 12 through the rotating shaft.

[0029] In one embodiment, such as Figure 3 As shown, the mounting bracket 11 has multiple threaded holes 114 on its top, and the fixing pin 15 has external threads that mate with the threaded holes 114.

[0030] In one embodiment, such as Figure 1-3 As shown, the connecting plate 9 has multiple screw holes 901, and the mounting bracket 11 has a groove 111. A bolt 10 is provided inside the groove 111, and one end of the bolt 10 is inserted into the screw hole 901. The mounting bracket 11 is fixedly installed by the bolt 10.

One end of the push rod 7 on the vacuum booster is provided with a threaded fork 5. A connecting pin 6 is provided on the threaded fork 5. A fixing hole 17 that cooperates with the connecting pin 6 is opened on the pedal arm 2. The threaded fork 5 is connected to the pedal arm 2 through the connecting pin 6.

[0032] The above embodiments of this utility model provide a car brake pedal with easy-to-adjust stroke. The pedal bracket 1 is installed by the mounting plate 8, and the pedal arm 2 is rotatably mounted on the pedal bracket 1. When it is necessary to adjust the stroke of the brake pedal 3, the fixing pin 15 at the top of the mounting bracket 11 is unscrewed, and the two sets of connecting blocks 16 move along the sliding groove 112 into different fixing grooves 113. The connecting blocks 16 drive the positioning block 12 to move through the rotating plate 17, and the positioning block 12 drives the limiting plate 14 to move. The distance between the limiting plate 14 and the mounting bracket 11 is adjusted. After the position of the limiting plate 14 is appropriate, the fixing pin 15 is screwed down. When the brake pedal 3 is pressed down, the pedal arm 2 stops moving after contacting the limiting plate 14, thus realizing the adjustment of the brake pedal stroke.

[0033] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
