Description

Technical Field

[0001] This utility model relates to the field of pedal technology, and in particular to a plastic pedal assembly with a damping structure. Background Technology

[0002] In traditional automotive hydraulic braking systems, the performance of the brake pedal plays a crucial role in vehicle safety and the driver's experience. However, the all-metal structure used in traditional automotive brake pedals has several drawbacks in practical applications. First, all-metal brake pedals typically employ a stamping and welding process. During welding, the high temperatures can easily cause deformation of the bracket. This deformation makes it extremely difficult to control the product's assembly dimensions, increasing the difficulty of quality control during production and potentially leading to misalignment between the brake pedal and other components after installation, thus affecting the performance and stability of the entire braking system. Second, the pedal operation generates significant noise, which can irritate the driver, distract their attention, and pose a potential threat to driving safety. Furthermore, the existing sheet metal stamping structure of the pedal arm, due to excessive twisting, makes it difficult to meet the requirements for return damping. Inadequate return damping leads to excessive pedal return, making it difficult for the driver to precisely control the position and force of the pedal, thus affecting the driving experience and reducing driving precision and comfort.

[0030] The main spindle bushing 3 has both ends passing through the bushing mounting hole, and the main spindle bushing 3 is welded to the inner wall of the bushing mounting hole.

[0031] There are two main shaft bushings 4, which are symmetrically arranged at both ends of the main shaft bushing 3. The main shaft bushings 4 can prevent the main shaft 7 from directly contacting the main shaft bushing 3, which helps to reduce the noise generated when stepping on the pedal.

[0032] Spring bushing 5 is located at one end of main shaft bushing 3. Spring bushing 5 can prevent damping spring 6 from directly contacting main shaft bushing 3, which helps to reduce noise generated when pedaling and improve driving comfort.

[0033] The damping spring 6 is sleeved on the outer wall of the spring bushing 5. One end of the damping spring 6 is connected to the inner wall of the mounting groove, and the other end of the damping spring 6 is connected to the brake arm 2. During the rotation of the brake arm 2, the damping spring 6 will be stretched or compressed, thereby providing buffer and damping force for the brake arm 2, making the movement of the brake arm 2 more stable and gentle, which is conducive to optimizing the pedal return effect.

[0034] The main spindle 7 has one end passing through the brake base 1, the two main spindle bushings 4 and the main spindle bushing 3 and extending out of the brake base 1.

[0035] Furthermore, as a preferred embodiment, spindle mounting holes 18 are provided through the inner walls on both sides of the mounting groove 17. The two spindle mounting holes 18 are arranged opposite each other. The brake arm 2, the spindle bushing 3 and the spring bushing 5 are all arranged between the two spindle mounting holes 18. One end of the spindle 7 passes through the two spindle mounting holes 18.

[0036] Furthermore, as a preferred embodiment, the ends of the two spindle bushings 4 that are far apart from each other have a limiting disk 21, and the inner walls of the two sides of the mounting groove 17 are provided with limiting grooves 22. The limiting grooves 22 are located in the outer peripheral direction of the spindle mounting hole 18, and the limiting disk 21 is rotatably disposed in the limiting groove 22.

[0037] Furthermore, as a preferred embodiment, it also includes: a retaining ring 8, an annular groove that mates with the retaining ring 8 is provided on one end of the main shaft 7, the retaining ring 8 is disposed in the annular groove, the retaining ring 8 abuts against the outer wall of the brake base 1, and the retaining ring 8 is used to ensure that the main shaft 7 will not come out of the brake base 1.

[0038] Furthermore, as a preferred embodiment, the other end of the spindle 7 has a limiting block 15, which is used to limit the axial movement of the spindle 7.

[0039] Furthermore, as a preferred embodiment, a spring mounting hole 19 is provided on the inner wall of the mounting groove. The spring mounting hole 19 is located between the two spindle mounting holes 18, and one end of the damping spring 6 is engaged with the spring mounting hole 19.

[0040] Furthermore, as a preferred embodiment, it also includes: a brake switch mounting bracket 9 and rivets 10. The brake base 1 has a plurality of bracket mounting holes 20, and each bracket mounting hole 20 is provided with a rivet 10. The brake switch mounting bracket 9 is connected to the brake base 1 through the rivets 10, and a brake switch is provided on the brake switch mounting bracket 9.

[0041] Furthermore, as a preferred embodiment, it also includes: a pedal cover 11, which covers the periphery of the pedal plate 16, and the pedal cover 11 is provided with anti-slip texture. Furthermore, the pedal cover 11 not only protects the pedal plate 16, but the anti-slip texture on the pedal cover 11 also increases the friction between the driver's foot and the pedal cover 11, preventing the foot from slipping during pedaling and improving operational safety.

[0042] Furthermore, as a preferred embodiment, it also includes: a quick-connect bracket 12, with a mounting base 13 provided on one side of the brake wall, the quick-connect bracket 12 being disposed on the mounting base 13, and the quick-connect bracket 12 being connected to the ball joint of the push rod of the external power booster via a ball hinge. Furthermore, when the driver depresses the pedal cover 11, the power booster's assistance can be transmitted to the braking system through the quick-connect bracket 12, thereby optimizing the braking effect.

[0043] Furthermore, as a preferred embodiment, the quick-connect bracket 12 has a slot, and the mounting base 13 is snapped into the slot. After the quick-connect bracket 12 and the mounting base 13 are initially snapped together, the quick-connect bracket 12 and the mounting base 13 can be connected by bolts to increase the connection strength.

[0044] Furthermore, as a preferred embodiment, a switch contact 14 is provided on the other side of the brake arm 2, and the switch contact 14 is operablely in contact with or away from the brake switch.

[0045] Furthermore, as a preferred embodiment, the brake base 1 is made of plastic and is injection molded. Moreover, plastic is not only lightweight, which is beneficial for vehicle weight reduction, but the injection molding process also ensures dimensional accuracy, thereby effectively avoiding the deformation problems associated with traditional metal welding.

[0046] Furthermore, as a preferred embodiment, the brake arm 2 is preferably configured as a hollow structure, and the brake arm 2 is formed by stamping and welding, thereby enabling the brake arm 2 to further reduce its weight while ensuring structural strength.

[0047] Furthermore, as a preferred embodiment, the spindle bushing 4 is made of plastic, which helps to reduce the overall weight of the pedal.

[0048] The working principle of this utility model is as follows: When the driver presses the pedal plate 16 covered by the pedal cover 11, the brake arm 2 will rotate around the main shaft 7. When the brake arm 2 rotates, the switch contact plate 14 on the other side of the brake arm 2 will contact the brake switch on the brake switch mounting bracket 9, thereby realizing the transmission of the brake signal. When the driver releases the pedal cover 11, the elastic force of the damping spring 6 can reset the brake arm 2, causing the switch contact plate 14 to separate from the brake switch.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
