Description

Technical Field

[0001] This utility model relates to the field of passenger vehicle pedal technology, and in particular to a suspended accelerator pedal for passenger vehicles. Background Technology

[0002] Passenger vehicles encompass sedans, minibuses, and light passenger vehicles with no more than nine seats. They are primarily used to transport passengers and personal belongings or temporary items. The accelerator pedal's main function is to control the opening of the engine throttle valve, thereby controlling the engine's power output. Passenger vehicles typically use a suspended accelerator pedal.

[0003] Existing suspended accelerator pedals have many structures that control the feel of the pedal, which are costly and cannot produce variable friction damping, resulting in a poor pedal feel.

[0004] Therefore, we propose a suspended accelerator pedal for passenger vehicles. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a passenger car suspended accelerator pedal, which can generate variable frictional lag through two parts, a friction block and a third spring, thereby improving the driving feel of the pedal arm. It uses fewer and simpler structures, which can reduce production costs.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A passenger vehicle suspended accelerator pedal, comprising:

[0008] The base and the pedal arm rotatably connected to the base;

[0009] The lower cover is located at the bottom of the base;

[0010] Among them, a first spring and a second spring are provided between the lower cover and the pedal arm;

[0011] The top of the lower cover has a placement groove below the pedal arm, and a friction block is placed in the placement groove. Below the friction block is a fifth spring groove, and a third spring is placed in the fifth spring groove. The friction block is located between the pedal arm and the placement groove, and the third spring is in a compressed state. When the pedal arm is stepped on, the friction between the pedal arm and the friction block generates variable frictional force.

[0012] Its further features are:

[0013] The base is rotatably connected to the pedal arm via a rotating shaft.

[0014] A circuit board is provided on one side of the base, and the circuit board is disposed in a circuit board cover plate on the other side. The circuit board cover plate is disposed on the base.

[0015] The bottom of the pedal arm is provided with a first spring groove and a second spring groove, the top of the lower cover is provided with a third spring groove below the first spring groove, and the top of the lower cover is provided with a fourth spring groove below the second spring groove.

[0016] The second spring groove is located outside the first spring groove.

[0017] One end of the first spring is disposed in the first spring groove, and the other end of the first spring is disposed in the third spring groove. One end of the second spring is disposed in the second spring groove, and the other end of the second spring is disposed in the fourth spring groove. The second spring is disposed outside the first spring.

[0018] The first spring is provided with sound-absorbing cotton.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model features a compact and reasonable structure. When the driver brakes, they depress the pedal arm, which rotates along its axis. Friction occurs between the pedal arm and the friction block. Influenced by a third spring, this friction generates variable frictional lag, resulting in damping and improving the driving feel of the pedal arm. The variable frictional lag is achieved by placing a third spring at the bottom of the friction block. Furthermore, it can be adjusted to match different customers' varying lag requirements, thus achieving the desired damping feel. Variable frictional lag is generated using only two components: the friction block and the third spring, improving the driving feel of the pedal arm. This design uses fewer components and is simpler in structure, reducing production costs. Attached Figure Description

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, a passenger car suspended accelerator pedal includes a pedal arm 1 and a base 2. The base 2 is rotatably connected to the pedal arm 1 via a pivot 11. A circuit board 4 is provided on one side of the base 2, and another side of the circuit board 4 is disposed in a circuit board cover 5. The circuit board cover 5 is disposed on the base 2.

[0028] The base 2 has a lower cover 3 at its bottom. The pedal arm 1 has a first spring groove 101 and a second spring groove 102 at its bottom. The second spring groove 102 is located outside the first spring groove 101. The lower cover 3 has a third spring groove 302 below the first spring groove 101 at its top. The lower cover 3 has a fourth spring groove 303 below the second spring groove 102 at its top. The fourth spring groove 303 is located outside the third spring groove 302. A first spring 6 and a second spring 7 are provided between the pedal arm 1 and the lower cover 3. One end of the first spring 6 is located in the first spring groove 101, and the other end of the first spring 6 is located in the third spring groove 302. One end of the second spring 7 is located in the second spring groove 102, and the other end of the second spring 7 is located in the fourth spring groove 303. The second spring 7 is located outside the first spring 6. Sound insulation cotton 10 is provided on the first spring 6.

[0029] On the other side of the top of the top cover 3, below the pivot 11 and the pedal arm 1, there is a placement groove 301. A movable friction block 9 is provided in the placement groove 301. A fifth spring groove 901 is provided at the bottom of the friction block 9. A third spring 8 is provided in the fifth spring groove 901. The bottom of the third spring 8 is in contact with the fifth spring groove 901.

[0030] In one specific embodiment, a limiting groove is provided on both sides of the fifth spring groove 901, and a limiting block is provided at both ends of the friction block 9. The limiting block of the friction block 9 is located in the limiting groove of the fifth spring groove 901. The friction block 9 is restricted by the cooperation of the limiting block and the limiting groove, so that the friction block 9 can move up and down and will not move completely to the outside of the fifth spring groove 901.

[0031] The third spring 8 is in a compressed state, and the elastic force of the third spring 8 supports the friction block upward.

[0032] When the driver brakes, they depress the pedal arm 1. The pedal arm 1 rotates along the pivot 11, and friction occurs between the pedal arm 1 and the friction block 9. Influenced by the third spring 8, this friction generates variable frictional lag, thus producing damping and improving the driving feel of the pedal arm 1. Variable frictional lag can be generated by placing the third spring 8 at the bottom of the friction block 9. Furthermore, it can be adjusted and matched according to different customers' varying lag requirements, thereby achieving the desired damping feel.

[0033] This application achieves variable frictional lag by using only two parts, friction block 9 and third spring 8, thereby improving the driving feel of pedal arm 1. It uses fewer components and has a simple structure, which can reduce production costs.

[0034] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
