Vehicle, pedal structure, and elastic mechanism for pedal

Abstract

The invention discloses a vehicle, a pedal structure and an elastic mechanism for a pedal. The elastic mechanism comprises a frame, and an elastic piece arranged on the frame, wherein one end of the elastic piece can be fixed, and the other end can be in moving fit with a pedal arm of the pedal; when the pedal arm is suffered from external force to enable the other end of the elastic piece to rotate by surrounding the frame so as to store energy, return force provided by the elastic piece in a rotation tangential direction of the other end of the elastic piece is increased in a monotone manner, and a force arm of the return force is increased in a monotone manner, that is, the force and the force arm are synchronously increased in a monotone manner without being counteracted, so that the torque of the pedal arm of the product of the force and the force arm is increased in a monotone manner, and an excellent pedal feeling can be provided under an effect of applying less force to users, that is, an excellent brake feeling is provided to drivers.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to an elastic mechanism for a pedal, a pedal structure with the elastic mechanism, and a vehicle provided with the pedal structure. Background technique [0002] In the brake pedal of the vehicle, its existing elastic mechanism mainly plays the role of reset and resistance adjustment during the working process of the brake pedal. The elastic mechanism of existing brake pedal is usually as figure 1 As shown, wherein, the pedal arm 11 is rotatably connected to the bracket 10 of the pedal, one end of the tension spring 13 is connected to the pedal arm, and the other end is fixedly connected to the bracket 10, and the pedal arm moves from figure 1 The shown initial state moves to the braking state and acts on the extension spring, and the force generated by the extension and contraction of the extension spring realizes the resistance adjustment and reset of the pedal.

AI Technical Summary

Problems solved by technology

[0003] However, there are certain deficiencies in the existing elastic mechanism

The way in which the pedal arm directly stretches the extension spring cannot provide the driver with a good braking feeling. During the braking action of the driver, the extension spring is stretched so that the contraction force of the extension spring increases monotonously, but the pedal arm rotates The moment arm of point motion decreases monotonously with the rotation of the pedal arm, and the torque is the product of the force and the moment arm. Since the change trend of the force and the moment arm is opposite, the two are offset to a certain extent, and the obtained torque The curve approximates a straight line with a small slope rising, so that a large force is required to act on the pedal arm to pull the extension spring, making it impossible to provide a good braking feeling for the driver
