Referring to fig. 1, the disclosed embodiment provides a brake pedal simulator including a first support 100, a second support 200, a foot pedal 300, a guide rod 400, and an elastic member 500. The first support frame 100 can be used as a bottom support for each component of the brake pedal simulator to support the brake pedal simulator, so that the stability of the brake pedal simulator is ensured, and the first support frame 100 can be placed on a horizontal working surface; the second support frame 200 is rotatably connected to the first support frame 100 to be capable of rotating downward relative to the first support frame 100; the pedal 300 is fixedly installed on the second support frame 200, so that the pedaling force of the driver can be transmitted to the second support frame 200 to rotate; two ends of the guide rod 400 are respectively rotatably connected with the first support frame 100 and the second support frame 200, and the guide rod 400 can axially move when the second support frame 200 rotates downwards relative to the first support frame 100, that is, the guide member 400 can be driven to simultaneously axially move when the second support frame 200 rotates downwards, and the guide rod 400 can rotate relative to the first support frame 100 and the second support frame 200, so that the rotating realizability of the second support frame 200 can be ensured; the elastic member 500 is used for providing resilience when the second support frame 200 rotates downwards and drives the guide rod 400 to move axially, that is, the guide rod 400 moves axially, so that the elastic member 500 is compressed to generate resilience, thereby providing a braking feeling for a driver, the elastic member 500 may include a first spring 510 and a second spring 520 which are serially connected and sleeved on the guide rod 400, and the first spring 510 and the second spring 520 have different rigidities, so that different braking states of the vehicle can be simulated by providing resilience with different sizes.

It should be noted that in the embodiments provided in the present disclosure, the "axially movable" of the guide rod 400 refers to the change of the connection length between the first support frame 100 and the second support frame 200, that is, at least one end of the guide rod 400 can move axially relative to the corresponding connection point in addition to the rotatable connection with the first support frame 100 and the second support frame 200, so that the length of the guide rod 400 between the two connection points formed by the first support frame 100 and the second support frame 200 can be changed to realize the relative rotation of the second support frame 200. The elastic member 500 is sleeved on the guide rod 400, that is, the elastic member 500 is sleeved on the portion of the guide rod 400 between the first support frame 100 and the second support frame 200, that is, the elastic member 500 is always located between two connection points formed by the guide rod 400 and the first support frame 100 and the second support frame 200, so that when the second support frame 200 rotates downwards relative to the first support frame 100 and drives the guide rod 400 to move axially, the connection length of the guide rod 400 between the first support frame 100 and the second support frame 200 is reduced, and the elastic member 500 can be compressed therewith to adapt to the change of the length of the guide rod 400. The elastic member 500 has a resilient force in an initial state, which can provide an initial pedal force, and can enable two ends of the elastic member 500 to elastically abut against two ends of the guide rod 400, thereby indirectly fixing the elastic member 500 on the guide rod 400. For the first spring 510 and the second spring 520 connected in series, the spring with lower rigidity is compressed first during the generation of the rebound force due to the difference in rigidity between the two springs, and the spring with higher rigidity starts to be compressed when the compression stroke reaches the limit, so that the driver can be provided with two different rebound force feelings to simulate, for example, mild braking and emergency braking of the vehicle. The number of the elastic members 500 is not limited in the present disclosure, and for example, it may further include more than two springs, and the stiffness of each spring may be set to be different, so that a plurality of different braking states of the vehicle may be simulated. In addition, the stiffness, the pitch, the initial length and other parameters of the first spring 510 and the second spring 520 can be calculated in advance according to the relation between the actual vehicle pedal force and the pedal angle, so that the actual driving experience can be further provided for the driver.

Further, referring to fig. 1 to 3, the first support frame 100 may include two first mounting plates 110 disposed opposite to each other, and the second support frame 200 may also include two second mounting plates 210 disposed opposite to each other, and the two second mounting plates 210 may be located between the two first mounting plates 110 and hinged by a third pin 600. The third pin 600 may include a cylindrical pin having an internal thread abutting between the two first mounting plates 110, and a threaded fastener such as a bolt may pass through the first mounting plates 110 from a side of the two first mounting plates 110 facing away from each other and be threadedly coupled with the cylindrical pin, so that the two first mounting plates 110 may be fixedly coupled. The second mounting plates 210 are rotatably sleeved outside the cylindrical pins, and shaft sleeves can be further sleeved on the cylindrical pins between the two second mounting plates 210, so that the third pin 600 can be protected, and the axial movement of the second mounting plates 210 can be limited. A gasket may also be disposed between the first mounting plate 110 and the second mounting plate 210 to reduce wear and noise therebetween. The hinge points of the first and second mounting plates 110 and 210 may be disposed at the respective end positions thereof so that a large mounting space may be provided for the guide bar 400, and the second mounting plate 210 may be formed with an inclination angle of less than 90 ° with the first mounting plate 110 in an initial mounting state to accommodate a pedaling direction of a driver. In addition, the first mounting plate 110 may be configured as a vertical plate extending in a horizontal direction, and a horizontal plate may be further connected to a bottom end thereof to be stably supported on the working surface.

According to some embodiments, referring to fig. 1, a first end of the guide rod 400 may be rotatably connected to the second support frame 200 through the connection block 410, and a second end may be rotatably connected to the first support frame 100 through the support plate 420, that is, the connection block 410 may be rotatable with respect to the second support frame 200, and the support plate 420 may be rotatable with respect to the first support frame 100. Wherein, the elastic member 500 may be located between the connecting block 410 and one side of the supporting plate 420 facing the connecting block 410, a fastening hole for fixedly connecting with the first end of the guide rod 400 may be formed on the connecting block 410, a through hole for the guide rod 400 to pass through may be correspondingly formed on the supporting plate 420, and the diameter of the second end of the guide rod 400 is greater than the diameter of the through hole so as to be able to abut against one side of the supporting plate 420 facing away from the connecting block 410. That is, in this embodiment, the first end of the guide rod 400 may be formed as a fixed end fixed with respect to the connection block 410, which may be rotated in synchronization with the connection block 410, and the second end of the guide rod 400 may be correspondingly formed as a free end axially movable with respect to the support plate 420, which may also be axially movable with respect to the support plate 420 while being rotated in synchronization with the support plate 420. During installation, the first end of the guide rod 400 passes through the through hole and is fixedly connected with the connecting block 410, and the second end of the guide rod 400 is propped against one side of the supporting plate 420 departing from the connecting block 410 by means of the elastic force of the elastic member 500, so that the initial fixation of the guide rod 400 is realized. When the second support frame 200 rotates downward, it drives the connecting block 410 and the guide rod 400 to move downward synchronously, the guide rod 400 moves axially along the through hole, and the second end of the guide rod gradually moves away from the support plate 420. The guide rod 400 may be configured as a bolt having a partial external thread, for example, the external thread may be formed at a position near the first end, and the fastening hole of the connecting block 410 may be a threaded hole, so that the first end of the guide rod 400 and the connecting block 410 are relatively fixed by a threaded connection, and the head of the bolt is just against and fixed on the supporting plate 420. In other embodiments, the first end of the guide rod 400 may be axially movable, and the second end may be relatively fixed, which is not limited in this disclosure.

Further, referring to fig. 1, a first spring 510 may be disposed near the connection block 410, a second spring 520 may be disposed near the support plate 420, and a spring bushing 430 for radially limiting the elastic member 500 may be coaxially sleeved outside the guide rod 400 to prevent the elastic member 500 from moving in a radial direction during the compression process. The spring bushing 430 may be clearance fit with the guide rod 400 to avoid obstructing axial movement of the guide rod 400. The number of the spring bushings 430 may be multiple, for example, three, and the three spring bushings 430 are respectively located between the connecting block 410 and the first spring 510, between the first spring 510 and the second spring 520, and between the second spring 520 and the supporting plate 420, so that both ends of the first spring 510 and the second spring 520 may be limited by the spring bushings 430, axial compression of the elastic member 500 is sufficiently ensured, and the spring bushings 430 between the first spring 510 and the second spring 520 may also serve to connect the first spring 510 and the second spring 520.

Still further, referring to fig. 2, the spring bushing 430 may include a first section 431 and a second section 432 arranged in an axial direction, and an outer diameter of the first section 431 is larger than an outer diameter of the second section 432, i.e., the first section 431 and the second section 432 have a stepped structure. Wherein, the inner diameter of the elastic member 500 is larger than the outer diameter of the second section 432 so as to fix the elastic member 500 configured as a spring on the second section 432, and the outer diameter of the elastic member 500 is smaller than the outer diameter of the first section 431 so as to enable the end of the elastic member 500 configured as a spring to abut against the corresponding spring bushing 430. The outer diameter of the second section 432 may be adaptively designed according to the inner diameters of the first spring 510 and the second spring 520, for example, the spring bushing 430 between the first spring 510 and the second spring 520 may include two second sections 432 located at both sides of the first section 431, and the outer diameters of the two second sections 432 are respectively matched with the inner diameters of the first spring 510 and the second spring 520. Thus, when the second support frame 200 rotates downward, the force applied by the connecting block 410 is sequentially transmitted to the spring bushing 430 adjacent thereto, the first spring 510, the spring bushing 430 between the first spring 510 and the second spring 520, and the spring bushing 430 adjacent to the support plate 420, thereby completing the compression of the first spring 510 or the second spring 520.

In an embodiment provided by the present disclosure, referring to fig. 1, the stiffness of the first spring 510 may be set to be greater than the stiffness of the second spring 520. Thus, when the vehicle is braked gently, the second spring 520 is compressed to provide resilience, and the first spring 510 moves downwards synchronously, namely, the process only needs the second spring 520 to provide resilience; when vehicle emergency braking, second spring 520 first produces the compression and provides the resilience force, and first spring 510 moves downwards in step, and when the compression stroke of second spring 520 reached the limit, first spring 510 began the compression and provides the resilience force to can provide the resilience force that the size is different from second spring 520, feel for the dynamics that the driver is different.

According to some embodiments, referring to fig. 2, the support plate 420 may include a first plate 421 formed with the through hole and two second plates 422 extending in the same direction from both ends of the first plate 421, i.e., the support plate 420 may be configured as a U-shaped plate, and the second plates 422 extend in a direction away from the guide bar 400 so as to be able to provide a certain movement space to the guide bar 400. The first support frame 100 may be mounted with the support block 120, the support block 120 may be formed with a U-shaped groove having an upward opening, and two side walls of the U-shaped groove may be hinged to the two second plates 422, respectively, so as to rotatably connect the guide rod 400 to the first support frame 100. The second plate 422 may be hinged with each side wall of the U-shaped groove by a separate rotation shaft to reserve a sufficient space for the axial movement of the guide bar 400.

The head diameter of the bolt is larger than the bore diameter of the kidney hole 111 to abut against the outer side of the first mounting plate 110 facing away from the support block 120. Through the waist-shaped hole 111, the position of the supporting block 120 can be adjusted along the horizontal direction, so that the initial angle of the second supporting frame 200 relative to the first supporting frame 100, namely the initial angle of the pedal plate 300, can be adjusted, and the simulation device is suitable for simulation of different vehicles.

Further, referring to fig. 3, in order to firmly fix the supporting block 120 on the first mounting plates 110 and prevent the supporting block from rotating, the first supporting frame 100 may further include a first pin 140 fixed between the two first mounting plates 110, and a horizontally extending first link 150 connected to the first pin 140 and the supporting block 120, one end of the first link 150 may be sleeved on the first pin 140, and the other end may penetrate through the supporting block 120 and be fixedly connected to the supporting block 120.
