The base 100 is connected with a vehicle body, the pedal arm 200 is installed on the base 100 and can be stepped on, due to the linkage connection of the rocker arm 300 and the pedal arm 200, the rocker arm 300 can be driven to rotate downwards when the pedal arm 200 is stepped on, and the rocker arm 300 can transmit pressure to the hysteresis assembly 400 when rotating downwards, so that the second friction surface 411 of the hysteresis assembly 400 abuts against the first friction surface 311 with certain pressure, and due to the fact that the hinged part 310 of the rocker arm 300 can rotate in the process that the pedal arm 200 is stepped on downwards, the friction force generated between the first friction surface 311 and the second friction surface 411 hinders the rotation of the rocker arm 300 through the hinged part 310, and then hysteresis force for hindering the rotation of the pedal arm 200 is formed.

In the above process, since the hysteresis unit 400 is coupled to the rocker arm 300 in an interlocking manner, the rocker arm 300 is coupled to the pedal arm 200 in an interlocking manner, the pedal arm 200 transmits the pressure to the second friction surface 411 of the hysteresis unit 400 through the rocker arm 300, and the first friction surface 311 moves relative to the second friction surface 411 as the hinge portion 310 rotates in the process, the hysteresis effect is provided very smoothly and stably

As shown in fig. 1 to 4, the hysteresis module 400 includes a rocker 410, the rocker 410 is swingably connected to the base 100, and when one end of the rocker 410 is pressed, the other end is tilted, the rocker 300 is connected to one end of the rocker 410 in a linkage manner to transmit pressure, the second friction surface 411 is located at the other end of the rocker 410, and when the rocker 300 presses one end of the rocker 410, the other end of the rocker 410 is tilted and applies pressure to the second friction surface 411.

The elastic member 420 is preferably a spring, and when the pedal arm 200 is depressed to a small extent during the actual depression of the pedal, the elastic member 420 is relatively easily compressed, so that the pressure transmitted to the rocker 410 is relatively small, and the friction force between the first friction surface 311 and the second friction surface 411 is relatively small, so that the hysteresis effect is relatively weak, and as the depression of the pedal arm 200 is increased, the elastic member 420 is substantially no longer compressed, and at this stage, the pressure of the rocker arm 300 is completely transmitted to the rocker 410, and at this time, the friction force between the first friction surface 311 and the second friction surface 411 is relatively large, so that the hysteresis effect is relatively strong, and when the pedal arm 200 is depressed to a maximum extent, the friction force between the first friction surface 311 and the second friction surface 411 is maximum, and the hysteresis effect is strongest.

Through the elastic piece 420, the hysteresis force of the pedal can be increased along with the increase of the stepping amplitude of the pedal arm 200, the hysteresis effect received at the initial stage of the pedal arm 200 being stepped is smaller, and the pedal arm 200 is more suitable for practical operation habits, in addition, the elastic piece 420 can also reset the pedal arm 200, after a driver loosens the pedal arm 200, the elastic piece 420 extends and pushes the rocker arm 300 to reset, and the rocker arm 300 can push the pedal arm 200 to reset in the resetting process.

The linkage portion 210 is hinged to the rocker arm 300, so that the pedal arm 200 can be linked with the rocker arm 300, and the pedal arm 200 and the rocker arm 300 can rotate relative to each other during the rotation of the pedal arm 200, thereby ensuring the smooth movement of the pedal arm 200 and the rocker arm 300.

As shown in fig. 1, 4 and 5, the hinge 310 is a wheel-shaped structure, the base 100 is provided with a support shaft 110, the support shaft 110 is inserted into the center of the hinge 310, and the hinge 310 can rotate around the support shaft 110. During the rotation of the rocker arm 300, the hinge portion 310 rotates around the support shaft 110, and since the hinge portion 310 is in a wheel-shaped structure, the first friction surface 311 is an arc surface, and the second friction surface 411 is configured corresponding to the first friction surface 311, such that the first friction surface 311 and the second friction surface 411 are complementary, and the first friction surface 311 and the second friction surface 411 can be kept in contact at all times during the rotation of the hinge portion 310 through the arc surface design of the wheel-shaped structure.

In brief, the larger the stepping range of pedal arm 200 is, the larger the hysteresis force received by pedal arm 200 is, and since pedal has elastic member 420, the magnitude of the stepping range of pedal arm 200 is related to the stepping force received, the hysteresis force is positively related to the stepping range and the stepping force, pedal arm 200 is located in the first stroke section just before stepping, and enters the second stroke section as pedal arm 200 continues stepping, in order to meet the operating habit of the driver, hysteresis force can be made to show a tendency of first small and then large as the stepping stroke increases by hysteresis component 400 of this pedal, the hysteresis force received by pedal arm 200 is very small when pedal arm 200 is in the first stroke section, and the hysteresis force received by pedal arm 200 is increased when pedal arm 200 is in the second stroke section, and stop when pedal arm 200 reaches the limit position.

For example, when the treading force F1 applied to the pedal arm 200 is 15.5N ± 3N, the rotation range of the pedal arm 200 is 1 ° or less and is located in the first stroke, and the hysteresis force H1 applied at this time is 25% or more of F1; when the pedal arm 200 is subjected to the treading force F2 of 35N ± 5N, the rotation amplitude of the pedal arm 200 is about 14.9 ± 0.5 ° and is located in the second stroke section, and the hysteresis force H2 applied at this time is equal to or greater than 25% of F2.
