Description
A rubber shock absorber for engines with good heat dissipation Technical Field
[0001] This utility model relates to the field of rubber vibration dampers, specifically an engine rubber vibration damper with good heat dissipation. Background Technology
[0002] Engine rubber shock absorbers are devices that utilize the elastic properties of rubber to reduce mechanical vibration, impact, and noise. They absorb and reflect vibration energy, preventing the propagation of vibration waves, thereby achieving the effects of shock absorption, noise reduction, and minimizing the damage caused by impacts.
[0003] Existing engine rubber shock absorbers absorb mechanical vibration energy through their elastic properties and dissipate it as heat, thus achieving a damping effect. If this heat cannot be dissipated in time, it may cause the shock absorber to overheat, affecting its performance and lifespan. Therefore, a new technical solution is needed to address this issue. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an engine rubber shock absorber with good heat dissipation effect. This solves the technical problem that when the current engine rubber shock absorber is used, it absorbs mechanical vibration energy through its elastic properties and converts it into heat energy for dissipation, thereby achieving the effect of shock absorption. However, if this heat cannot be dissipated in time, it may cause the shock absorber to overheat, affecting its performance and lifespan.
[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: designing an engine rubber vibration damper with good heat dissipation effect, including a metal part and a rubber body, the rubber body completely covering the outside of the metal part, a frustum groove is opened in the middle of the bottom end of the rubber body, a damping cavity is opened in the inner cavity of the rubber body, a damping fluid is provided in the damping cavity, the damping fluid is dimethyl silicone oil, and multiple rectangular holes are opened at the bottom end of the rubber body, and multiple rectangular holes are connected to the frustum groove.
[0006] Preferably, the metal part is a steel plate, and a rectangular frame is provided on the surface of the metal part, and the rectangular frame is placed inside the rubber body.
[0007] Preferably, the bottom of the metal part is provided with multiple support plates, and the multiple support plates are respectively distributed in a staggered manner with multiple rectangular holes in the rubber body.
[0008] Preferably, a reinforcing plate is provided on the upper side of the inner cavity of the rubber body, and both the reinforcing plate and the rubber body are provided with threaded connection holes.
[0009] Preferably, the rubber body has four first fixing holes and the metal part has four second fixing holes, with the four first fixing holes corresponding to and adapted to the four second fixing holes respectively.
[0010] Preferably, the metal part, the rectangular frame, and the support plate are integrally die-cast.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model combines a rubber body, metal parts, a damping cavity, a damping fluid, a frustum groove, and a rectangular hole. When the engine is running, it drives the rubber damper to vibrate, thereby absorbing part of the engine vibration energy. At the same time, the damping fluid vibrates in the damping cavity, generating intense shear motion and absorbing part of the engine vibration energy. Thus, the cooperation between the damping fluid and the rubber damper can improve the vibration damping performance of the rubber damper, further enhancing its vibration damping effect. After the energy of the engine vibration is converted into heat energy by the rubber body and the damping fluid, the excellent heat absorption properties of the damping fluid (dimethyl silicone oil) can absorb the heat from the rubber damper. Meanwhile, the rectangular hole improves the airflow inside the frustum groove, thereby accelerating the heat dissipation effect inside the rubber body, further improving the heat dissipation effect of the rubber damper, and further enhancing its performance and service life.
[0013] 2. By setting up a support plate, this utility model can support the rubber body during installation, preventing the rubber body from being stressed and deformed at the bottom, which would reduce or block the opening of the rectangular hole and affect the heat dissipation effect of the rubber body.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0020] Example 1: An engine rubber vibration damper with good heat dissipation effect, as shown in Figures 1 to 4, includes a metal part 3 and a rubber body 1. The rubber body 1 completely covers the outside of the metal part 3. A frustum groove 13 is formed in the middle of the bottom end of the rubber body 1. A damping cavity 2 is formed in the inner cavity of the rubber body 1. A damping fluid 21 is provided in the damping cavity 2. The damping fluid 21 is dimethyl silicone oil. A plurality of rectangular holes 12 are formed at the bottom end of the rubber body 1, and the plurality of rectangular holes 12 are connected to the frustum groove 13.
[0021] During operation, when the engine runs, it drives the rubber vibration damper to vibrate, thus absorbing some of the energy from the engine vibration. Simultaneously, the damping fluid 21 vibrates within the damping chamber 2, generating intense shear motion and absorbing some of the engine vibration energy. Therefore, the combination of the damping fluid 21 and the rubber vibration damper improves the damping performance of the rubber vibration damper, further enhancing its damping effect. The energy from the engine vibration is converted into heat energy in the rubber body 1 and the damping fluid 21. Due to the excellent heat absorption properties of the damping fluid 21 (dimethyl silicone oil), it absorbs heat from the rubber vibration damper. At the same time, the airflow inside the frustum-shaped groove 13 is improved through the rectangular hole 12, thereby accelerating the heat dissipation effect inside the rubber body 1, further improving the heat dissipation effect of the rubber vibration damper, and ultimately enhancing its performance and service life.
[0022] Specifically, referring to Figure 2, the metal part 3 is a steel plate, and a rectangular frame 31 is provided on the surface of the metal part 3. The rectangular frame 31 is placed inside the rubber body 1. The rectangular frame 31 can increase the shear force of the rubber body 1 and further improve the strength of the rubber body 1.
[0023] Furthermore, referring to Figure 4, the bottom of the metal part 3 is provided with multiple support plates 33, and the multiple support plates 33 are respectively staggered with multiple rectangular holes 12 and placed inside the rubber body 1. Through the setting of the support plates 33, the support plates 33 can support the rubber body 1 during installation, so as to avoid the rubber body 1 being stressed, deforming at the bottom and reducing or blocking the opening of the rectangular holes 12, thus affecting the heat dissipation effect of the rubber body 1.
[0024] It is worth noting that, referring to Figure 2, a reinforcing plate 4 is provided on the upper side of the inner cavity of the rubber body 1. Both the reinforcing plate 4 and the rubber body 1 are provided with threaded connection holes 41. The rubber body 1 is provided with four first fixing holes 11, and the metal part 3 is provided with four second fixing holes 32. The four first fixing holes 11 correspond to and are adapted to the four second fixing holes 32 respectively. The threaded connection holes 41 facilitate the connection of the rubber body 1 to the engine. The first fixing holes 11 and the second fixing holes 32 facilitate the passage of bolts to fix the rubber body 1 to the frame. At the same time, the reinforcing plate 4 can increase the strength of the connection between the engine and the rubber body 1, further improving the firmness of the rubber body 1 fixed to the engine.
[0025] It is worth noting that, referring to Figures 3 and 4, the metal part 3, the rectangular frame 31, and the support plate 33 are integrally die-cast. This integral molding is used to improve the connection strength between the metal part 3 and the rectangular frame 31 and the support plate 33, and further improve the overall strength of the rubber body 1.
