Specifically, an installation space can be defined in the housing 1, and both the first magnetic attraction piece 2 and the second magnetic attraction piece 3 can be arranged in the installation space. Wherein, the one end at installation space is fixed to first magnetism piece 2 of inhaling, and second magnetism piece 3 can be inhaled towards the direction removal that is close to or keeps away from first magnetism piece 2.

Wherein, the first magnetic part 2 is a magnet, and the second magnetic part 3 is an electromagnet. When the pedal 200 needs a power assisting force in a right direction, a current in a certain direction can be applied to the second magnetic attraction piece 3, so that a magnetic force for mutual attraction is generated between the first magnetic attraction piece 2 and the second magnetic attraction piece 3, and the magnetic force can drive the second magnetic attraction piece 3 to move in the right direction. When the pedal 200 needs the assisting force in the left direction, the direction of the current flowing into the second magnetic attraction member 3 can be changed, so that the first magnetic attraction member 2 and the second magnetic attraction member 3 generate a magnetic force repelling each other, and the magnetic force can drive the second magnetic attraction member 3 to move left. It can be understood that, also can inhale a 2 to set to the electro-magnet with first magnetism, inhale a 3 to set to magnet with the second, can also inhale a 2 and a 3 sets to the electro-magnet simultaneously is inhaled to the second magnetism with first magnetism, can select to set up according to the in-service use demand.

Specifically, the moving push rod 4 can move relative to the housing 1. The movable push rod 4 can play a role in transferring the treading force of the pedal 200, and when the driver treads the pedal 200, the treading force can be transferred to the second magnetic attraction piece 3 through the movable push rod 4, so that the second magnetic attraction piece 3 can be driven to move. In the example shown in fig. 1, the moving push rod 4 is provided on the left side of the housing 1, the left end of the moving push rod 4 is connected to the pedal 200, and the right end of the moving push rod 4 protrudes into the housing 1. When the driver steps on the pedal 200, the moving push rod 4 can transmit the stepping force to the second magnetic attraction piece 3, and thus the moving push rod 4 can drive the second magnetic attraction piece 3 to move rightwards.
As shown in fig. 1, the first elastic member 5 can be disposed in the housing 1, and two ends of the first elastic member 5 are respectively connected to the first magnetic attraction member 2 and the second magnetic attraction member 3, the second elastic member 6 can also be disposed in the housing 1, one end of the second elastic member 6 is disposed on the housing 1, the length of the second elastic member 6 is smaller than that of the first elastic member 5, and the second elastic member 6 is compressed after the second magnetic attraction member 3 moves a set distance. Specifically, the first elastic member 5 and the second elastic member 6 may be disposed together in a manner of being superimposed on each other. The second elastic element 6 can be sleeved on the first elastic element 5, and an assembly gap is arranged between the first elastic element 5 and the second elastic element 6, so that the first elastic element 5 and the second elastic element 6 can work independently and do not influence each other.

When the pedal feeling simulator 100 works, the moving push rod 4 can transmit the pedaling force to the second magnetic attraction piece 3, and the second magnetic attraction piece 3 moves and cooperates with the inner wall of the housing 1 to compress the first elastic piece 5. When the second magnetic attraction piece 3 moves a set distance, the second elastic piece 6 starts to be compressed. The first elastic member 5 and the second elastic member 6 may transmit their elastic forces to the pedal 200 by moving the push rod 4, thereby providing the pedal 200 with a pedal feel preset force, which may allow the driver to perceive the pedal feel. It is understood that the overlapping arrangement of the first elastic member 5 and the second elastic member 6 can improve the operational reliability of the pedal feel simulator 100. For example, when at least one of the second elastic member 6, the first magnetic member 2 and the second magnetic member 3 is broken down, the pedal feel simulator 100 can still work normally without affecting the actual use of the driver.

The operation of the pedal feel simulator 100 according to the embodiment of the present invention will be described in detail with reference to the drawings.
When the pedal feeling simulator 100 works, the pedal 200 can transmit the treading force to the second magnetic attraction piece 3 through the moving push rod 4, and the second magnetic attraction piece 3 is matched with the inner wall of the shell 1 to compress the first elastic piece 5. When the second magnetic attraction piece 3 moves a set distance, the second elastic piece 6 starts to be compressed. The first elastic member 5 and the second elastic member 6 may transmit their elastic forces to the pedal 200 by moving the push rod 4, whereby the pedal-feel preset force may be provided. If the pedal feel preset force provided by the first elastic member 5 and the second elastic member 6 is larger than the pedal braking force required in the running state of the real vehicle, the pedal feel simulator 100 provides the assist force in the right direction. The magnitude and direction of the current introduced into the first magnetic attraction piece 2 and/or the second magnetic attraction piece 3 are adjusted, so that the first magnetic attraction piece 2 and the second magnetic attraction piece 3 generate a magnetic force of mutual attraction. If the pedal feeling preset force provided by the first elastic member 5 and the second elastic member 6 is smaller than the pedal braking force required by the running state of the real vehicle, the pedal feeling simulator 100 provides an assisting force in the left direction, and adjusts the magnitude and the direction of the current introduced into the first magnetic attraction member 2 and/or the second magnetic attraction member 3, so that the first magnetic attraction member 2 and the second magnetic attraction member 3 generate a magnetic force repelling each other. When the pedal feel simulator 100 stops working, the magnetic force generated between the first magnetic attraction piece 2 and the second magnetic attraction piece 3 disappears, and the first elastic piece 5 and the second elastic piece 6 can drive the second magnetic attraction piece 3 to move to the initial position by means of the elastic force. Through the design, the pedal braking force acting on the movable push rod 4 can be matched with the running state of the real vehicle, so that the pedal feeling effect when the driver steps on the pedal 200 can be improved, and the operation comfort of the driver is improved.
According to the pedal feeling simulator 100 of the embodiment of the invention, by arranging the first magnetic attraction piece 2 and the second magnetic attraction piece 3, the direction and the magnitude of the force acting on the movable push rod 4 can be adjusted by changing the direction and the magnitude of the current introduced into the first magnetic attraction piece 2 and/or the second magnetic attraction piece 3, so that the pedal braking force is matched with the running state of the real vehicle, and the pedal feeling effect and the braking performance of the pedal feeling simulator 100 can be improved.

Specifically, the first mounting seat 31 can move relative to the housing 1, and the first mounting seat 31 can play a role of fixing the second magnetic attraction piece 3. When the movable push rod 4 transmits the treading force to the first mounting seat 31, the first mounting seat 31 can drive the second magnetic attraction piece 3 to move. For example, as shown in fig. 1, the first mounting seat 31 is disposed at the left end of the housing 1, and the right end of the first mounting seat 31 extends into the housing 1 and is connected to the second magnetic attraction piece 3 by means of screws.

Alternatively, the second mounting seat 21 may be connected with the housing 1 by means of a screw connection.
Alternatively, the first elastic member 5 and the second elastic member 6 may be fixed to the second mounting seat 21, respectively, whereby the internal structure of the pedal feel simulator 100 may be more compact. Specifically, the second mounting seat 21 can also play a role of supporting the first elastic element 5 and the second elastic element 6, so that the first elastic element 5 and the second elastic element 6 which are placed in an overlapping manner can be ensured to work independently and not to influence each other. In the specific example shown in fig. 1, the pedal feel simulator 100 further includes a second spring seat 22, the second spring seat 22 is disposed at the left end of the second mounting seat 21, and the second mounting seat 21 and the second spring seat 22 are connected together by means of a screw connection.

Specifically, the transmission lever 42 can function to transmit the pedaling force. When the pedal 200 is stepped on, the transmission rod 42 may transmit the stepping force to the brake push rod 41, and thus, the brake push rod 41 may push the second magnetic attracting member 3 to move.

When the pedal feel simulator 100 operates, the transmission ball 42a can convert the pedaling force of the pedal 200 into a rightward thrust by rotating itself and transmit the rightward thrust to the brake push rod 41. Therefore, the force transmission between the pedal 200 and the pedal feel simulator 100 can be smoother, a better pedal feel effect can be achieved, and the service life of the pedal feel simulator 100 can be prolonged.

Specifically, the through hole may be formed in an end of the housing 1 away from the first magnetic element 2, and the moving push rod 4 may be connected to the housing 1 through the anti-separation portion. It can be understood that, when the removal push rod 4 resets, first elastic component 5 and second elastic component 6 can rely on its self elastic force to promote the removal push rod 4 and resume to initial position, and anticreep portion can prevent to remove push rod 4 and the second magnetism and inhale 3 complex tip roll-off from the through-hole to can play fine connection effect.

It can be understood that, when the first magnetic attraction element 2 and/or the second magnetic attraction element 3 are energized, a magnetic field is generated between the first magnetic attraction element 2 and the second magnetic attraction element 3, and the magnetic isolation element 7 can prevent the magnetic field from spreading to the surroundings, so as to prevent the parts around the first magnetic attraction element 2 and the second magnetic attraction element 3 from being magnetized, and ensure the normal operation of the pedal feeling simulator 100.
According to some embodiments of the present invention, the first magnetic attracting element 2 and the second magnetic attracting element 3 are electromagnets respectively, so as to facilitate the operation and improve the pedal feeling effect of the pedal feeling simulator 100.
