Description

Technical Field

[0001] The utility model relates to the technical field of accelerator pedals, in particular to a floor type accelerator pedal. Background Art

[0002] The main function of the accelerator pedal is to control the opening of the engine throttle, thereby controlling the power output of the engine. The traditional accelerator pedal is connected to the throttle through a throttle cable or a pull rod. With the continuous development of automotive electronic technology, the application of electronic throttle is becoming more and more extensive. When the driver steps on the accelerator pedal of the electronic throttle, it actually transmits a throttle pedal position sensor signal to the engine ECU.

[0003] The existing floor-type accelerator pedal cannot produce a variable friction hysteresis damping feeling when the accelerator is stepped on, thereby making the driver's driving feeling poor.

[0004] For this purpose, we propose a floor-mounted accelerator pedal. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a floor-type accelerator pedal, so that the friction between the roller bracket and the friction block produces force hysteresis, thereby producing a damping foot feel, and because a first spring is arranged above the friction block, a variable friction force hysteresis damping feel design can be achieved through the first spring, thereby improving the driver's driving foot feel.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A floor-type accelerator pedal, comprising:

[0008] Base plate;

[0009] A pedal, rotatably connected to the base plate;

[0010] The pedal is provided with a connecting frame, the connecting frame is rotatably connected to a roller bracket, a roller capable of rolling is provided at the bottom of the roller bracket, and the roller is arranged on the bottom plate;

[0011] A first placement groove is arranged at the bottom of the pedal in the connecting frame, a movable friction block is arranged in the first placement groove, the bottom of the friction block is arc-shaped and contacts with the top of the roller bracket, and a first spring is arranged between the top of the friction block and the first placement groove.

[0012] It is further characterized by:

[0013] A second placement groove is also provided at the bottom of the pedal, and a return shock-absorbing pad is provided in the second placement groove to reduce the vibration generated when the pedal is released.

[0014] One end of the bottom plate is in a stepped shape, and a dead-point shock-absorbing pad is provided at the bottom plate at the step to reduce vibration.

[0015] The base plate and the pedal are rotatably connected via a rotating shaft, and a third spring is sleeved on the rotating shaft, one end of the third spring abuts against the base plate, and the other end of the third spring abuts against the pedal.

[0016] The connecting frame is connected to the roller bracket via a rotating shaft, and the roller and the roller bracket are rotatably arranged.

[0017] The roller bracket is sleeved with a second spring.

[0018] A sensor assembly is arranged outside the connecting frame.

[0019] The pedal and the roller bracket are made of plastic to reduce the weight of the entire vehicle.

[0020] The beneficial effects of the utility model are as follows:

[0021] The utility model has a compact and reasonable structure and is easy to operate. The friction between the roller bracket and the friction block generates force hysteresis, thereby generating a damping foot feeling. Moreover, because a first spring is arranged above the friction block, a variable friction force hysteresis damping feeling design can be achieved through the first spring, thereby improving the driver's driving foot feeling. Moreover, it can be adjusted and matched according to different force hysteresis requirements of different customers, thereby achieving the damping foot feeling desired by the customer.

[0022] At the same time, the utility model also has the following advantages:

[0023] (1) The impact noise of the pedal is reduced by the stop-point shock absorber, which improves the NVH performance and enhances the driving comfort.

[0024] (2) When the pedal is released, the roller bracket moves to the initial position and can contact the return shock pad, reducing the noise of pedal rebound, improving NVH performance, and enhancing driving comfort.

[0025] (3) The pedals and roller brackets are made of plastic, replacing the original metal materials, which reduces the weight of the vehicle, improves the endurance of new energy vehicles, and also reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The specific implementation of the utility model is described below in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 6 As shown, a floor-type accelerator pedal comprises a base plate 1 and a pedal 2, the base plate 1 and the pedal 2 are rotatably connected via a rotating shaft 101, and a third spring 103 is sleeved on the rotating shaft 101, one end of the third spring 103 abuts against the base plate 1, and the other end of the third spring 103 abuts against the pedal 2, one end of the base plate 1 is stepped, and a dead-point shock-absorbing pad 102 is provided at the step of the base plate 1 for reducing vibration.

[0035] Two stop point damping pads 102 may be provided, and the two stop point damping pads 102 are respectively provided on both sides of the bottom plate 1. The material of the stop point damping pad 102 may be rubber, which reduces the impact noise of stepping on the pedal 2, improves NVH performance, and improves driving comfort.

[0036] The pedal 2 is provided with a connecting frame 201, and a first placement groove 203 and a second placement groove 204 are provided at the bottom of the pedal 2 in the connecting frame 201, a friction block 205 is placed in the first placement groove 203, and the friction block 205 can move in the first placement groove 203, and a first spring 207 is provided between the friction block 205 and the top of the first placement groove 203, and a return shock-absorbing pad 206 is provided in the second placement groove 204 to reduce the vibration generated when the pedal 2 is released. A sensor assembly 208 is provided outside the connecting frame 201.

[0037] The connecting frame 201 is connected to the roller bracket 301 through the rotating shaft 202. The roller bracket 301 and the connecting frame 201 are rotatably connected, and the roller bracket 301 is sleeved with a second spring 302. Two second springs 302 can be provided, and the two second springs 302 are respectively sleeved on both sides of the roller bracket 301. The bottom of the roller bracket 301 is provided with a roller 3. The roller 3 and the roller bracket 301 are rotatably provided, and the roller 3 can roll, and the roller 3 is provided on the bottom plate 1. The bottom of the friction block 205 is arc-shaped and contacts the top of the roller bracket 301.

[0038] The pedal 2 and the roller bracket 301 are made of plastic, replacing the original metal material, reducing the weight of the entire vehicle, improving the endurance of the new energy vehicle, and also reducing costs.

[0039] When the pedal 2 is stepped on, the roller bracket 301 rotates along the rotating shaft 202, and the roller bracket 301 drives the roller 3 to roll on the bottom plate 1. The friction between the roller bracket 301 and the friction block 205 generates force hysteresis, thereby generating a damping foot feeling. Because a first spring 207 is arranged above the friction block 205, the first spring 207 can be used to design a variable friction force hysteresis damping feeling, thereby improving the driver's driving foot feeling. Moreover, it can be adjusted and matched according to different force hysteresis requirements of different customers, so as to achieve the damping foot feeling desired by the customer.

[0040] When the pedal 2 is released, the roller bracket 301 moves to the initial position and can contact the return shock-absorbing pad 206, thereby reducing the rebound noise of the pedal 2, improving the NVH performance, and improving the driving comfort.
