Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a brake pedal mounting structure. Background Technology

[0002] Existing automotive brake pedal mounting structures typically employ a fixed-angle design, which is difficult to adapt to different driver heights, foot postures, and operating habits, easily leading to pedal fatigue or insufficient control precision. While some adjustable structures achieve angle adjustment through simple bolt fixing, they suffer from unreliable locking, cumbersome disassembly and assembly, and are prone to component loosening due to vibration after prolonged use, affecting the stability and safety of the braking system. Furthermore, traditional structures have low modularity, requiring complete disassembly of the brake pedal for maintenance, increasing repair costs and time. Therefore, a brake pedal mounting structure that combines angle adjustability, stable connection, and convenient maintenance is proposed. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] See Figure 1-3 As shown in the figure, a brake pedal mounting structure in this embodiment includes a brake pedal arm 1. A connecting mounting structure 2 is welded and fixedly mounted on the front end of the brake pedal arm 1. A brake pedal body 3 is welded and fixedly mounted on the upper end of the connecting mounting structure 2. The connecting mounting structure 2 includes a hollow base 201, a toothed sleeve 202, a rubber sleeve 203, a hexagonal screw 204, a hexagonal nut 205, a limiting clamp 206, and a curved panel 207.

[0016] Specifically, the brake pedal arm 1, as the basic support component of the entire brake pedal mounting structure, connects the pedal operating mechanism in the cockpit to the lower connecting mounting structure 2, transmitting the force of the driver pressing the brake pedal to the braking system; the connecting mounting structure 2, through the meshing structure of the toothed sleeve 202 with the hollow base 201 and the limiting clamp 206, realizes multi-level adjustment of the tilt angle of the brake pedal body 3, improving the ergonomic experience; the combination of the rubber sleeve 203, hexagonal screw 204 and nut 205 ensures reliable locking of the adjusted angle and avoids loosening; the detachable modular design facilitates disassembly and replacement of parts, reducing maintenance costs; the brake pedal body 3 is the component that the driver directly presses.

[0017] See appendix Figure 1-3 As shown, the connection and installation structure 2 includes a hollow base 201 welded and fixed to the front end of the brake pedal arm 1, a toothed sleeve 202 inserted into the through hole of the hollow base 201, a rubber sleeve 203 glued and fixed to the inside of the toothed sleeve 202, a hexagonal screw 204 inserted into the rubber sleeve 203, a hexagonal nut 205 rotated and fitted onto the front end of the hexagonal screw 204, a limiting clamp 206 nested at both ends of the toothed sleeve 202, and a curved panel 207 welded and fixed to the upper end of the limiting clamp 206.

[0018] Specifically, the hollow base 201 serves as the base for the connecting installation structure, welded and fixed to the front end of the brake pedal arm 1, providing a through hole for mounting the gear sleeve 202; the rubber sleeve 203 buffers the rigid contact between the hexagonal screw 204 and the gear sleeve 202, reducing vibration and noise, while the elastic material enhances the impact resistance of the connecting structure and extends the component's lifespan; the hexagonal screw 204 passes through the rubber sleeve 203 and the gear sleeve 202, serving as the central axis of the connecting installation structure 2, fixing the limiting clamp 206, the curved panel 207, and the brake pedal body 3, and tightening it with the hexagonal nut 205 to lock the angular position of the gear sleeve 202 within the hollow base 201; the hexagonal nut 205 rotates and fits onto the front end of the hexagonal screw 204, clamping the limiting clamp 206, the gear sleeve 202, and the hollow base 201 with tightening force, fixing the tilt angle of the brake pedal body 3; the limiting clamp 206 serves as the mounting base for the curved panel 207, supporting the weight of the brake pedal body 3.

[0019] See appendix Figure 1-2 As shown, the upper surface of the curved panel 207 is welded to the lower surface of the brake pedal body 3.

[0020] Specifically, the curved panel 207 is welded and fixed to the upper end of the limiting clamp 206. The curved surface design adapts to the bottom contour of the brake pedal body 3, increasing the welding contact area, ensuring a firm connection, and transmitting the force of the brake pedal body 3 to the limiting clamp 206 and the toothed sleeve 202, thus realizing the transmission of force.

[0021] See appendix Figure 2As shown, the hollow base 201 has multiple toothed grooves evenly distributed in the through hole, the limiting clamp 206 has multiple toothed grooves evenly distributed in the through hole, and the toothed sleeve 202 has multiple toothed strips evenly distributed and fixed on the outer side. The toothed strips of the toothed sleeve 202 are engaged in the toothed grooves of the hollow base 201 and the limiting clamp 206.

[0022] Specifically, by inserting the toothed sleeve 202 into the through hole of the hollow base 201, the outer toothed rack engages with the toothed groove of the hollow base 201 and the limiting clamp 206 to achieve graded adjustment and locking of the tilt angle of the brake pedal body 3, realize the toothed positioning during angle adjustment, and fix the tilt angle of the brake pedal body 3.

[0023] See appendix Figure 2 As shown, the rubber sleeve 203 has multiple transverse grooves evenly distributed on its inner side.

[0024] Specifically, the rubber sleeve 203 is attached to the inside of the toothed sleeve 202, and the horizontal groove on the inner wall increases the friction with the hexagonal screw 204 to prevent the screw from loosening.

[0025] During operation of this utility model: When adjusting the angle, use a tool to remove the hexagonal nut 205 from the hexagonal screw 204, causing the toothed sleeve 202 to exit the hollow base 201. Take care not to damage the retaining tooth structure during operation to avoid affecting the accuracy of subsequent angle adjustments. According to driving needs, manually rotate the brake pedal body 3, causing the toothed sleeve 202 to rotate. After adjusting to a suitable tilt angle, press the toothed sleeve 202 and gently shake the brake pedal body 3 back and forth until the toothed sleeve 202 is inserted into the hollow base 201, and the retaining toothed strip outside the toothed sleeve 202 engages with the hollow base 201. The retaining groove of the limiting clamp 206 prevents the hollow base 201 from rotating with the limiting clamp 206, and allows for graded adjustment and initial locking of the angle. After determining the appropriate tilt angle, the hexagonal nut 205 is rotated onto the front end of the hexagonal screw 204. The hexagonal nut 205 is tightened with a tool. Through the cooperation of the hexagonal nut 205 and the hexagonal screw 204, the limiting clamp 206, the toothed sleeve 202 and the hollow base 201 are clamped together, fixing the tilt angle of the brake pedal body 3. At this time, the rubber sleeve 203 will also further prevent the hexagonal screw 204 from loosening through friction.

[0026] During disassembly and maintenance, use tools to unscrew the hex nut 205 and pull out the hex screw 204 to separate the limiting clamp 206 from the hollow base 201. Record the installation direction and position of each component during disassembly for accurate installation during reassembly. At this time, the brake pedal body 3 can be cleaned, inspected, or replaced. Remove the limiting clamp 206 in sequence and pull out the toothed sleeve 202. If the rubber sleeve 203 is aged or damaged, it can be directly torn off from the inside of the toothed sleeve 202 for replacement. Since the hollow base 201 is welded and fixed to the brake pedal arm 1, it does not need to be disassembled if there is no damage. Only its retaining groove needs to be inspected and cleaned. During reassembly, install the new or cleaned components in sequence to ensure that each component is installed in place, the retaining structure is tightly engaged, and the screws and nuts are tightened to complete the reassembly after maintenance.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
