Description

Technical Field

[0001] The utility model relates to the technical field of electronic braking, in particular to a sheath shock pad for electronic braking. Background Art

[0002] The braking system is an important guarantee for the safe driving of automobiles. Compared with the traditional hydraulic braking system, the electronically controlled braking system has many advantages such as simple structure, fast braking response, high control precision, flexible layout, and consistent pedal characteristics; and it is easy to integrate with the vehicle dynamic control system, can meet the requirements of the regenerative braking system of electric vehicles and hybrid vehicles, and has good development prospects.

[0003] With the research and development of electronic braking, the vacuum booster is replaced and optimized compared with the traditional braking, and the direct connection between the brake pedal and the brake wheel cylinder is cancelled in the control braking system. When the pedal link moves, it drives the metal parts to collide with the metal shell, resulting in abnormal noise and impact force, which makes the driver unable to experience a good driving environment. In order to consider the comfort of the driver, a sheath shock pad is added at the connection to ensure good use by the driver. Therefore, the sheath shock pad comes into being. Content of the Utility Model

[0004] To solve the technical problems in the background art, the utility model proposes a sheath shock pad for electronic braking.

[0005] A sheath shock pad for electronic braking proposed by the utility model includes a connecting part, the connecting part is an annular rubber body, the two end faces of the connecting part are respectively a first end face and a second end face, the first end face is provided with a first annular protrusion, the second end face is provided with a second annular protrusion, the first annular protrusion and the second annular protrusion are opposite to each other, and an annular groove is formed on the outer side surface of the connecting part.

[0006] Preferably, the side surface of the first annular protrusion is an arc surface protruding in the direction away from the first end face.

[0007] Preferably, the side surface of the second annular protrusion is an arc surface protruding in the direction away from the second end face.

[0008] Preferably, the axes of the first annular protrusion and the second annular protrusion coincide with the axis of the connecting part.

[0009] Preferably, the annular groove is formed at the middle position of the outer side surface of the connecting part.

[0010] Preferably, the cross-section of the annular groove is U-shaped, and the opening faces the outer side wall of the connecting part.

[0011] Preferably, the sheath shock pad is integrally vulcanized and formed of rubber.

[0012] In the present utility model, a sheath shock pad for electronic braking is proposed, which facilitates a good driving experience for the driver. When used with a traditional brake pedal, since a feedback disc is installed at the front end of the brake pedal to isolate it from the metal part, it avoids abnormal noises caused by the collision of metal with metal during braking and the impact force that prevents the driver from experiencing a good driving environment. Therefore, by adding a sheath shock pad pedal on the metal in electronic braking, when the driver steps on the brake pedal, the basic performance of the rubber part can be used to eliminate the abnormal noise of metal collision during braking and achieve the effect of buffering and shock absorption;

[0013] The end face is designed with a convex part so that it can match the grooves of the corresponding metal parts in both positive and negative directions, thereby reducing the risk of assembly errors caused by the need to identify the positive and negative directions;

[0014] The U-shaped annular groove enables the product to be better stuck in the metal cylinder during assembly with the metal cylinder to prevent use defects such as abnormal braking noises caused by falling off.

[0015] The additional aspects and advantages of the present utility model will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present utility model. Description of the Drawings

[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0021] Such as Figures 1 - 3An electronic braking sheath shock pad shown in the figure includes a connecting part 1. The connecting part 1 is an annular rubber body. The two end faces of the connecting part 1 are respectively a first end face and a second end face. The first end face is provided with a first annular protrusion 2, and the second end face is provided with a second annular protrusion 3. The first annular protrusion 2 and the second annular protrusion 3 face each other. The end faces are designed with protruding parts so that they can match the grooves of the corresponding metal parts in both positive and negative directions, thereby reducing the risk of assembly errors caused by the need to identify the positive and negative directions.

[0022] An annular groove 4 is formed on the outer side surface of the connecting part 1.

[0023] Preferably, the side surface of the first annular protrusion 2 is an arc surface protruding away from the first end face.

[0024] Preferably, the side surface of the second annular protrusion 3 is an arc surface protruding away from the second end face.

[0025] Preferably, the axes of the first annular protrusion 2 and the second annular protrusion 3 coincide with the axis of the connecting part 1.

[0026] The arc surface increases the thickness of the sheath shock pad, and the design of the arc surface is more likely to undergo elastic deformation, thereby absorbing external forces and achieving the effect of buffering and shock absorption.

[0027] Preferably, the annular groove 4 is formed at the central position of the outer side surface of the connecting part 1.

[0028] Preferably, the cross-section of the annular groove 4 is U-shaped, and the opening faces the outer side wall of the connecting part 1.

[0029] The buffer shock pad is located between the metal cylinder block 5 and the metal connecting sleeve 6. A sheath shock pad is installed at the through hole where the brake pedal rod 7 is connected to the metal cylinder block 5. The edge of the through hole is clamped in the annular groove 4. A part of the sheath shock pad is located inside the metal cylinder block 5, and a part is located outside the metal cylinder block 5. The annular groove 4 enables this product to be better stuck in the through hole of the metal cylinder block 5 during assembly with the metal sleeve to prevent use defects such as abnormal braking noises caused by falling off. The sheath shock pad is sleeved on the outside of the brake pedal rod 7. The first annular protrusion 2 of the part of the sheath shock pad located inside the metal cylinder block 5 contacts the metal connecting sleeve 6. When the brake pedal rod 7 moves, it drives the metal connecting sleeve 6 to move. When the brake pedal rod 7 moves, it drives the metal connecting sleeve 6 to collide with the outer shell of the metal cylinder block 5. During braking, the abnormal noise and impact force caused by the collision between metal and metal. Now, a sheath shock pad is added at the connection between the metal connecting sleeve 6 and the metal cylinder block 5. The basic performance of the rubber part is used to eliminate the abnormal noise of metal collision caused during braking and achieve the effect of buffering and shock absorption, ensuring good use by the driver. The dust cover 8 is used to isolate external dust.

[0030] Preferably, the sheath shock pad is integrally vulcanized from rubber.
