[0026] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] Reference below Figure 1 and Figure 2 The electronic booster 100 according to an embodiment of the present invention is described. The electronic booster 100 can reduce noise and vibration when the piston 2 returns.

[0028] refer to Figure 1 As shown, the electronic booster 100 according to an embodiment of the present utility model includes: a housing 1, a piston 2 and a shock absorber 3. The piston 2 is movably arranged in the housing 1. Along the moving direction of the piston 2, the housing 1 has a mounting wall 12 opposite to the piston 2. The shock absorber 3 is fixed to the mounting wall 12. Along the moving direction of the piston 2, at least part of the shock absorber 3 is located on the side of the mounting wall 12 facing the piston 2. The shock absorber 3 is suitable for abutting against the piston 2.

[0029] In which, the shell 1 can be constructed with a accommodating space 11, and at least part of the structure of the shock absorber 3 and the piston 2 are located in the accommodating space 11. The piston 2 can move relative to the shell 1 along a first direction. When the driver steps on the brake pedal, the piston 2 moves in a direction away from the shock absorber 3. When the driver releases the brake pedal, the piston 2 moves in a direction close to the shock absorber 3 and abuts against the shock absorber 3. That is, the piston 2 returns to its original position at this time.

[0030] As some embodiments of the present invention, the shock absorbing member 3 may be fixed to the mounting wall 12 of the housing 1 by means of bolt connection, snap connection or threaded connection.

[0031] The shock absorber 3 is elastic and can be made of rubber material. The shock absorber 3 can be elastically deformed under the action of external force. The shock absorber 3 can collide with the returning piston 2. The shock absorber 3 has a buffering effect. The shock absorber 3 will elastically deform when colliding with the piston 2. The elastic deformation of the shock absorber 3 can absorb the impact energy of the piston 2 when it returns, so as to reduce the vibration and noise when the shock absorber 3 collides with the piston 2. In addition, the shock absorber 3 can reduce the probability of wear caused by multiple return impacts of the piston 2.

[0032] As some embodiments of the present invention, the shock absorber 3 can be made of other non-metallic materials, as long as the non-metallic material can undergo elastic deformation to absorb impact energy, thereby having the effect of shock absorption and noise reduction.

[0033] In the above embodiment, by installing the shock absorber 3 on the mounting wall 12 of the housing 1, the returning piston 2 can collide with the shock absorber 3. The shock absorber 3 has a buffering effect to reduce the vibration and noise when the piston 2 returns, thereby improving the user's car experience and improving the vehicle's NVH (noise, vibration and acoustic roughness - Noise, Vibration, Harshness) performance.

[0034] In some embodiments of the present invention, Figure 1 As shown, the shock absorbing member 3 is detachably mounted on the mounting wall 12 .

[0035] Among them, the shock absorber 3 can be fixed to the mounting wall 12 by means of bolt connection, clip connection or threaded connection, so that the shock absorber 3 can be easily removed from the mounting wall 12, thereby reducing the difficulty of replacing the shock absorber 3, reducing the work difficulty of maintenance personnel, and saving maintenance costs.

[0036] In some embodiments of the present invention, the mounting wall 12 is formed with a mounting hole 14 , and the shock absorbing member 3 is assembled in the mounting hole 14 .

[0037] The shock absorber 3 can be fixedly assembled in the mounting hole 14. The shock absorber 3 can be fixed to the mounting wall 12 by bolting, snapping, or threaded connection, thereby securing the shock absorber 3 to the mounting hole 14. The shock absorber 3 can also be fixedly connected to the mounting hole 14 of the mounting wall 12 via an intermediate connecting member to secure the shock absorber 3 to the mounting hole 14. By assembling the shock absorber 3 in the mounting hole 14, the shock absorber 3 is easily fixedly connected to the mounting wall 12, facilitating installation and replacement of the shock absorber 3.

[0038] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the electronic booster 100 may further include: a connecting member 4 , the connecting member 4 and the shock absorbing member 3 are fixedly connected, and the connecting member 4 and the mounting wall 12 are fixedly connected.

[0039] Among them, the connecting member 4 is used to fix the shock absorber 3 to the mounting wall 12. The connecting member 4 can be made of materials such as stainless steel or aluminum alloy. The connecting member 4 can be constructed as an annular structure. The connecting member 4 can be connected to the shock absorber 3 by interference fit connection, adhesive connection, etc. The connecting member 4 can be connected to the mounting wall 12 by threaded fit connection, snap connection or bolt connection. The connecting member 4 is easy to disassemble from the mounting wall 12, so that the electronic booster 100 can easily replace the shock absorber 3 to reduce the difficulty of the maintenance personnel's work.

[0040] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the connecting member 4 is arranged on the side wall of the shock absorber 3 and is arranged around the shock absorber 3 along the circumference of the shock absorber 3. The inner wall of the mounting hole 14 is formed with a first threaded portion, and the outer side wall of the connecting member 4 facing away from the shock absorber 3 is formed with a second threaded portion that cooperates with the first threaded portion.

[0041] Among them, the shock absorber 3 can be constructed into a cylindrical shape, and the outer peripheral wall of the cylinder is the side wall of the shock absorber 3. The connecting member 4 can be arranged on the side wall of the shock absorber 3. The connecting member 4 can be sleeved on the shock absorber 3. The inner wall of the mounting hole 14 is formed with a first threaded portion, and the outer side wall of the connecting member 4 away from the shock absorber 3 can be formed with a second threaded portion. The first threaded portion can be matched with the second threaded portion to make the connecting member 4 threadedly connected to the mounting wall 12. The threaded connection installation method is simple and easy to disassemble, which can reduce the difficulty of replacing the connecting member 4 and the shock absorber 3.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a mounting groove 31 may be formed on the side wall of the shock absorber 3 . The mounting groove 31 is arranged around the shock absorber 3 along the circumference of the shock absorber 3 , and a portion of the connecting member 4 is mounted in the mounting groove 31 .

[0043] Among them, part of the structure of the connecting member 4 can be located in the mounting groove 31, and the size of the connecting member 4 along the first direction can be slightly larger than the size of the mounting groove 31 along the first direction, so that the connecting member 4 and the mounting groove 31 can be connected by interference fit, so that the connecting member 4 can be more tightly fixed in the mounting groove 31, so that the connecting member 4 and the shock absorber 3 can be more stably and reliably connected, which can reduce the probability of the shock absorber 3 being out of the preset position, which is conducive to improving the structural stability of the electronic booster 100.

[0044] In some embodiments of the present invention, Figure 1 As shown, a limiting boss 13 is further formed on the inner wall of the mounting hole 14 . The limiting boss 13 is located on the side of the connecting member 4 facing the piston 2 . The limiting boss 13 is suitable for abutting against the connecting member 4 for limiting position.

[0045] Among them, the limiting boss 13 is located between the connecting member 4 and the piston 2, and the end surface of the limiting boss 13 facing the connecting member 4 can abut against the connecting member 4 to limit the movement of the connecting member 4 along the first direction toward the piston 2, so that the connecting member 4 and the shock absorber 3 can be in the correct position. When the connecting member 4 is installed on the mounting wall 12, the connecting member 4 can be screwed in until the connecting member 4 abuts against the limiting boss 13. At this time, the installation of the connecting member 4 is completed, which can avoid excessive installation of the connecting member 4. By setting the limiting boss 13, it is beneficial to install the connecting member 4 and the shock absorber 3 in the correct position, which can further reduce the difficulty of fixing the connecting member 4 on the mounting wall 12.

[0046] As some embodiments of the present invention, the limiting boss 13 can be constructed as an annular structure, and the limiting boss 13 can be arranged circumferentially along the mounting hole 14, so that the connecting member 4 and the limiting boss 13 can be more fully abutted and matched to avoid installation position deviation. At the same time, the annular limiting boss 13 can further limit the movement of the connecting member 4 along the first direction toward the piston 2.

[0047] In some embodiments of the present invention, Figure 1 As shown, a boss structure 32 is formed on the end surface of the shock absorber 3 facing the piston 2 .

[0048] Among them, the boss structure 32 is located on the end face of the shock absorber 3 facing the piston 2. The boss structure 32 is used to abut against the end of the piston 2 facing the shock absorber 3. The boss structure 32 can collide with the returning piston 2. The boss structure 32 can first undergo elastic deformation when colliding with the returning piston 2, which is beneficial to reducing the main deformation of the shock absorber 3.

[0049] As some embodiments of the present application, the boss structure 32 can be constructed as a continuous circular ring structure, which can increase the abutment area between the boss structure 32 and the piston 2, and is more conducive to reducing the main body deformation of the shock absorber 3.

[0050] In some embodiments of the present invention, Figure 1 As shown, the electronic booster 100 further includes a push rod 5 , which passes through the mounting wall 12 and the shock absorber 3 , and is fixedly connected to the piston 2 .

[0051] Among them, the push rod 5 has two opposite ends, one end of the push rod 5 is connected to the brake pedal, and the other end of the push rod 5 is fixedly connected to the piston 2. When the driver steps on the brake pedal, the push rod 5 moves along the first direction toward the piston 2 to push the piston 2 to move along the first direction away from the shock absorber 3. When the driver releases the pedal, the push rod 5 and the piston 2 both move in the direction opposite to the direction of movement when the driver steps on the brake pedal.

[0052] In some embodiments of the present invention, the shock absorber 3 may be formed with a hole, and the push rod 5 may be inserted through the hole formed in the shock absorber 3. Furthermore, the push rod 5 is inserted through the mounting hole 14 of the mounting wall 12. By inserting the push rod 5 through the mounting wall 12 and the shock absorber 3, the electronic booster 100 can be made more compact, reducing the space occupied by the electronic booster 100 in the vehicle and improving the space utilization of the vehicle.

[0053] A vehicle according to an embodiment of the present invention includes the electronic booster 100 of the above-described embodiment. By installing a shock absorber 3 on the mounting wall 12 of the housing 1, the returning piston 2 collides with the shock absorber 3. The shock absorber 3 provides a buffering effect, reducing vibration and noise during the return of the piston 2. This improves the user experience and enhances the vehicle's NVH (Noise, Vibration, and Harshness) performance.
