Increased, so that when the mounting seat 2 moves toward the supporting assembly 1, the outer diameter of the pressing fit section 211 cooperating with the damping assembly 3 gradually increases, so that when the supporting assembly 1 moves toward the mounting seat 2, the damping assembly 3 can gradually press the pressing fit section 211, and in the gradual pressing process, the friction between the inner circumferential wall of the damping assembly 3 and the outer circumferential wall of the pressing fit section 211 gradually increases, ensuring the reliability of the simulator assembly 100 of the brake pedal, and the damping assembly 3 is sleeved on the outside of the pressing fit section 211, which can reduce the requirements for dimensional accuracy during production, thereby reducing production costs, and is less affected by environmental factors such as external temperature, which can improve reliability in use.

[0038] According to the brake pedal simulator assembly 100 of the embodiment of the utility model, the outer diameter of the press-fit section 211 of the mounting column 21 is constructed to gradually decrease in the direction approaching the support assembly 1, so that the damping assembly 3 can gradually press the press-fit section 211 to generate friction between the damping assembly 3 and the press-fit section 211, which can reduce the dimensional accuracy requirements during production and thus reduce production costs. It is less affected by environmental factors such as external temperature, which can improve reliability of use, achieve better use effects, and have a wider range of applications.

[0039] In some embodiments, the damping assembly 3 includes a first elastic member 31 and a first damping member 32, which are radially arranged in sequence outside the press-fit section 211, and the outer peripheral wall of the first elastic member 31 is suitable for pressing against the inner wall of the support assembly 1, and the inner peripheral wall of the first damping member 32 is suitable for pressing against the outer peripheral wall of the press-fit section 211.

[0041] Furthermore, the first damping member 32 is sleeved outside the press-fit section 211, that is, the inner peripheral wall of the first damping member 32 can contact the outer peripheral wall of the press-fit section 211, and when the first elastic member 31 applies elastic force to the first damping member 32, the inner peripheral wall of the first damping member 32 can press against the outer peripheral wall of the press-fit section 211 to generate friction, and the first elastic member 31 is sleeved outside the first damping member 32, and when the first elastic member 31 is expanded by external force, the outer peripheral wall of the first elastic member 31 can press against the inner wall of the support assembly 1 , so that when the press-fit section 211 moves toward the direction close to the support assembly 1, the press-fit section 211 can apply a radially outward supporting force to the first damping member 32, and the first elastic member 31 can be expanded under the force to press against the inner wall of the support assembly 1. At this time, the first elastic member 31 can apply a radially inward elastic force to the first damping member 32 to press the first damping member 32 against the outer peripheral wall of the press-fit section 211. The structure is simple and the reliability of the fit between the first damping member 32 and the press-fit section 211 can be ensured.

[0042] In some embodiments, the first elastic member 31 is configured as a wavy ring spring; and / or, the first damping member 32 is configured as a damping ring; and / or, a mounting groove 131 is formed on the inner wall of the hollow mounting cavity 13, and the first elastic member 31 and the first damping member 32 are both installed in the mounting groove 131, and in the axial direction of the mounting column 21, the first elastic member 31 and the first damping member 32 are both limitedly engaged with the inner end surface of the mounting groove 131.

When the second buffer member 6 is arranged on the intermediate support seat 12, the end surface of the intermediate support seat 12 facing the end support seat 11 may be provided with a groove-like structure open toward the end support seat 11, and the second buffer member 6 may be installed in the groove-like structure and protrude at least partially toward the end support seat 11.

[0061] Furthermore, the second buffer member 6 can be configured as a rubber member, and the second buffer member 6 can be configured as an annular structure or a plurality of buffer protrusions, etc. When the second buffer member 6 is configured as a plurality of buffer protrusions, the plurality of buffer protrusions can be distributed circumferentially between the end support seat 11 and the middle support seat 12, and when the end support seat 11 moves toward the middle support seat 12 to the extreme position, the second buffer member 6 can buffer the end support seat 11 to avoid a sense of frustration during use, thereby improving the user experience.

[0062] In some embodiments, the intermediate support seat 12 includes a first seat body 121 and a second seat body 122 connected axially, one end of the second elastic member 4 is pressed against the first seat body 121, and one end of the third elastic member 5 is pressed against the second seat body 122, and an installation groove 131 for accommodating the damping assembly 3 is defined between the first seat body 121 and the second seat body 122.

[0063] Specifically, the support assembly 1 is provided with an end support seat 11 and an intermediate support seat 12, and the intermediate support seat 12 is connected to a side of the end support seat 11 close to the mounting seat 2, and Figure 1-Figure 2 as well as Figure 4 As shown, the middle support seat 12 is provided with a first seat body 121 and a second seat body 122, and the first seat body 121 and the second seat body 122 can be connected by means of snap connection, etc., the first seat body 121 is arranged on a side close to the mounting seat 2, and the second seat body 122 is arranged on a side close to the end support seat 11, and one end of the second elastic member 4 can be pressed against the first seat body 121, and the other end can be pressed against the mounting seat 2, one end of the third elastic member 5 can be pressed against the second seat body 122, and the other end can be pressed against the end support seat 11, and an installation groove 131 is defined between the first seat body 121 and the second seat body 122, and the damping assembly 3 is arranged in the installation groove 131, that is, the damping assembly 3 is located between the second elastic member 4 and the third elastic member 5, so that the damping assembly 3 can be pressed against the press-fit section 211 after the second elastic member 4 is compressed, thereby ensuring the user experience.

[0064] And when the brake pedal simulator assembly 100 is actually used, it can be divided into three operating stages. In the first operating stage, the driver can step on the brake pedal, so that the end support seat 11 can move toward the middle support seat 12 to compress the second elastic member 4. At this time, the second elastic member 4 can transmit the force to the third elastic member 5 through the middle support seat 12, and as the second elastic member 4 is continuously compressed, the end support seat 11 can contact the second buffer member 6 and compress the second buffer member 6 until the stroke of the second elastic member 4 ends. During this process, the push rod 14 can drive the second damping member 15 to move with the end support seat 11 in the direction close to the mounting seat 2, and friction can be generated between the second damping member 15 and the inner wall of the damping chamber 212.

[0065] Furthermore, as the support assembly 1 moves, the inner circumferential wall of the first damping member 32 can move along the outer circumferential wall of the end of the mounting column 21. At this time, the first damping member 32 is basically non-deformed, so that the first elastic member 31 is also non-deformed, and the friction force between the inner circumferential wall of the first damping member 32 and the outer circumferential wall of the end of the mounting column 21 can be ignored.

[0066] The second operation stage is when the stroke of the second elastic member 4 ends, and the force applied by the driver acts on the support assembly 1, so that the force can compress the third elastic member 5. During this process, the second damping member 15 still generates friction with the damping chamber 212, and the first damping member 32 continues to move relative to the mounting column 21, so that the first damping member 32 can be pressed against the press-fit section 211, so that the first damping member 32 expands radially outward, so that the first elastic member 31 is deformed by force, and thus generates a radially inward elastic force, which generates friction between the first damping member 32 and the press-fit section 211, and as the support assembly 1 continues to move, the elastic force generated by the first elastic member 31 also increases, thereby increasing the friction.

[0067] In the third stage of operation, the push rod 14 is pressed against the first buffer member 22, and as the support assembly 1 continues to move, the first buffer member 22 is compressed until the end of the stroke. During this process, the friction force generated between the first damping member 32 and the press-fit section 211 and the friction force generated between the second damping member 15 and the damping chamber 212 are consistent with the form of the second stage of operation, and after the driver removes the force, the first buffer member 22, the second elastic member 4 and the third elastic member 5 recover to reset the first damping member 32 and the second damping member 15. At this time, friction forces in opposite directions can be generated between the first damping member 32 and the press-fit section 211 and between the second damping member 15 and the damping chamber 212. This friction force can slow down the reset speed of the support assembly 1, etc., avoid problems such as the brake pedal hitting the foot, and improve the user experience.

[0070] According to the vehicle of the embodiment of the utility model, the outer diameter of the press-fit section 211 of the mounting column 21 is constructed to gradually decrease in the direction approaching the support assembly 1, so that the damping assembly 3 can gradually press the press-fit section 211 to generate friction between the damping assembly 3 and the press-fit section 211, which can reduce the requirements for dimensional accuracy during production, thereby reducing production costs, and is less affected by environmental factors such as external temperature, thereby improving reliability of use, achieving better use effects, and having a wider range of applications.
