Specific embodiments

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please refer to Figures 1 to 6 , to achieve the above object, the present utility model provides the following technical solutions:

[0022] An automotive engine end cover includes an end cover body 1, wherein a plurality of heat dissipation fins 2 are provided on the outer side of the end cover body 1, and the heat dissipation fins 2 are integrally provided with the end cover body 1; a mounting table 3 is provided inside the end cover body 1, wherein the mounting table 3 is fixedly connected to the end cover body 1 by bolts; a fixing plate 4 is provided on one side of the mounting table 3, and a bearing fixing hole 5 is provided at one end of the mounting table 3 away from the fixing plate 4; an accommodating groove 6 is provided inside the mounting table 3, and the accommodating groove 6 communicates with the bearing fixing hole 5; a mounting groove 7 is provided inside the end cover body 1, and the fixing plate 4 is arranged in the mounting groove 7; a buffer sleeve 8 is provided in the accommodating groove 6, and a through hole 9 corresponding to the bearing fixing hole 5 is provided at the central position of the buffer sleeve 8.

[0023] The end cover body 1 is the main structure of the engine end cover and is usually made of a metal material with high strength and high heat resistance (such as aluminum alloy) to ensure that it can withstand the high temperature and mechanical stress generated during engine operation; the heat dissipation fins 2 are closely and evenly distributed on the outer side of the end cover body 1, and the heat dissipation fins 2 and the end cover body 1 are made by a casting integral molding process to form an integral structure; the main function of the heat dissipation fins 2 is to increase the surface area, thereby improving the heat exchange efficiency, helping the engine to dissipate heat quickly and preventing overheating; the mounting platform 3 is a platform provided inside the end cover body 1 for supporting and fixing other components, and the mounting platform 3 is connected to the end cover body 1 by bolts, which not only ensures the firmness of the installation but also facilitates subsequent disassembly and maintenance; the fixing plate 4 is a flat plate structure for fixing the mounting platform 3, and the fixing plate 4 is firmly installed in the mounting groove 7, and the presence of the fixing plate 4 ensures the stability and reliability of the mounting platform 3; the bearing fixing hole 5 is a round hole located at one end of the mounting platform 3 away from the fixing plate 4 for installing a bearing. The bearing is a crucial component in the engine. It supports the rotation of the shaft and reduces friction and wear. The size and shape of the bearing fixing hole 5 need to match the selected bearing; the accommodating groove 6 is a space opened inside the mounting platform 3 for accommodating the buffer sleeve 8, and the design and size of the accommodating groove 6 need to match the buffer sleeve 8 to ensure that the buffer sleeve 8 can be stably installed in the accommodating groove 6; the buffer sleeve 8 is an elastic sleeve structure. It is installed in the accommodating groove 6 and surrounds the bearing fixing hole 5. A through hole 9 corresponding to the bearing fixing hole 5 is opened at the center position of the buffer sleeve 8 to allow the installation of the bearing. The main function of the buffer sleeve 8 is to absorb and disperse the vibration and impact generated during engine operation, thereby protecting the bearing and the end cover from damage, realizing the functions of efficient heat dissipation, stable support, and buffer shock absorption, and providing a strong guarantee for the stable operation of the engine.

[0024] Please refer to Figure 3 、 Figure 5 As an embodiment of the present utility model, one end of the buffer sleeve 8 is fixedly connected to the bottom of the mounting groove 7, and the other end of the buffer sleeve 8 abuts against the inner wall of the accommodating groove 6.

[0025] In the above-mentioned solution, one end of the buffer sleeve 8 is closely connected to the bottom of the mounting groove 7 inside the end cover body 1 by welding, bolt connection or other reliable fixing methods. This fixed connection ensures the stability of the buffer sleeve 8 on the end cover and the reliability of long-term use; the other end of the buffer sleeve 8 tightly abuts against the inner wall of the accommodating groove 6. This abutment not only provides additional support for the buffer sleeve 8 but also ensures its correct position in the accommodating groove 6, preventing movement or misalignment during engine operation.

[0026] When the engine is running, vibrations and shocks are generated. If these vibrations and shocks are not controlled, they can cause damage to the engine and its components. The design of the buffer sleeve 8 is precisely to absorb these vibrations and shocks, convert them into heat energy or other forms of energy, and disperse them into the surrounding structure. Since the buffer sleeve 8 closely surrounds the bearing fixing hole 5, it can also provide additional protection for the bearing. When the bearing is subjected to vibrations or shocks, the buffer sleeve 8 can reduce the direct action of these forces on the bearing, thereby reducing the wear and failure risk of the bearing. By absorbing vibrations and shocks, the buffer sleeve 8 can effectively extend the service life of the engine end cover, bearing, and other related components, which reduces the maintenance and replacement costs and improves the reliability and economy of the whole vehicle. In some designs, the fixed connection and abutting method of the buffer sleeve 8 can have a certain degree of adjustability, allowing for fine-tuning according to needs during the installation process to ensure the best buffer effect and support stability.

[0027] Through its unique installation method and functional design, the buffer sleeve 8 plays a crucial buffering and shock-absorbing role on the engine end cover, not only protecting the bearing and other components from damage caused by vibrations and shocks, but also extending the service life and reliability of the entire engine system.

[0028] Please refer to Figure 5 , as an embodiment of the present utility model, a rubber gasket 10 is provided on one side of the buffer sleeve 8 close to the installation groove 7, and the periphery of the rubber gasket 10 is an arc transition surface.

[0029] In the above-described solution, the rubber gasket 10 serves as the interface material between the buffer sleeve 8 and the bottom of the mounting groove 7. Its primary function is to provide an additional sealing effect. By closely fitting to the bottom of the mounting groove 7, the rubber gasket 10 can prevent dust, moisture, or other contaminants from entering the gap between the buffer sleeve 8 and the mounting groove 7, thereby protecting the internal structure and bearings from contamination and corrosion. Due to its inherent elastic properties, the rubber gasket 10 can further absorb and disperse vibration energy during engine operation. When vibration is transmitted to the buffer sleeve 8, the rubber gasket 10 can act as an additional shock-absorbing layer, reducing the direct impact of vibration on the end cover and bearings and improving the overall shock-absorbing effect. The softness and elasticity of the rubber gasket 10 can also protect the bottom of the mounting groove 7 from scratches or damage that may be caused by the direct pressure of the buffer sleeve 8. This protective effect ensures the integrity of the end cover structure and the reliability of long-term use. The arc transition surface design around the rubber gasket 10 can significantly reduce the risk of stress concentration. When subjected to pressure or vibration, the arc shape can distribute stress more evenly, avoiding excessive local stress at the edges, thereby extending the service life of the rubber gasket 10 and the entire end cover. The arc transition surface also makes it easier for the rubber gasket 10 to align with the bottom of the mounting groove 7 and the buffer sleeve 8 during installation. This design reduces friction and resistance during installation, improving the installation efficiency and accuracy.

[0030] Please refer to Figure 3 , as an embodiment of the present utility model, a plurality of buffer and shock-absorbing blocks 11 are provided on the side of the buffer sleeve 8 close to the accommodating groove 6. One end of the buffer and shock-absorbing block 11 is fixedly connected to the buffer sleeve 8, and the other end of the buffer and shock-absorbing block 11 abuts against the bottom of the inner cavity of the accommodating groove 6.

[0031] In the above-mentioned scheme, the main function of the buffer shock-absorbing block 11 is to further enhance the shock-absorbing ability of the buffer sleeve 8, wherein the buffer shock-absorbing block 11, as an additional shock-absorbing layer, can absorb and disperse more vibration energy when the engine is running, thereby more effectively reducing the impact of vibration on the end cover, bearings and other related components; the buffer shock-absorbing block 11 is usually optimized according to the shape and size of the accommodating groove 6 to ensure that they can be evenly distributed between the buffer sleeve 8 and the bottom of the inner cavity of the accommodating groove 6. This layout helps to achieve a more balanced shock-absorbing effect and prevent excessive vibration or stress concentration in certain areas; one end of the buffer shock-absorbing block 11 is tightly connected to the buffer sleeve 8 by bolt connection, adhesive or other reliable fixing methods. This fixed connection ensures the stability of the buffer shock-absorbing block 11 on the end cover and the reliability of long-term use; the other end of the buffer shock-absorbing block 11 is tightly abutted against the bottom of the inner cavity of the accommodating groove 6 This abutment not only provides additional support for the buffer shock-absorbing block 11, but also ensures its correct position in the accommodating groove 6, preventing movement or dislocation during engine operation; the buffer shock-absorbing block 11 is usually made of materials with high elasticity, high wear resistance and high fatigue resistance, such as rubber, polyurethane or other synthetic elastomers, which can maintain stable performance when subjected to repeated vibration and impact, and are not easy to deform or damage; the combination of the buffer sleeve 8 and multiple buffer shock-absorbing blocks 11 forms a multi-level shock-absorbing system, which can more effectively absorb and disperse vibration energy, improve the overall shock-absorbing effect, and protect the engine and its components from damage by vibration and impact; by enhancing the shock-absorbing effect and optimizing the layout design, the combination of the buffer sleeve 8 and the buffer shock-absorbing block 11 also improves the reliability and durability of the engine end cover, helps to reduce the cost of maintenance and replacement, and improves the economy and reliability of the vehicle.

[0032] Please refer to Figures 2 to 4 As an embodiment of the present utility model, the shape of the fixing plate 4 is matched with the notch of the mounting groove 7, and the thickness of the fixing plate 4 is equivalent to the depth of the mounting groove 7.

[0033] In the above-described solution, the shape of the fixing plate 4 is designed to precisely match the notch of the mounting groove 7. This design ensures that the fixing plate 4 can be accurately inserted and fixed within the mounting groove 7, avoiding misalignment or wobbling that may occur during installation. Since the shape of the fixing plate 4 is adapted to the notch of the mounting groove 7 and its thickness is equivalent to the depth of the mounting groove 7, this tight fit enhances the stability of the fixing plate 4 within the mounting groove 7. The fixing plate 4 is typically made of materials with high strength, high wear resistance, and high fatigue resistance to ensure that it can withstand the high temperature and mechanical stress generated during engine operation. Common materials include high-strength steel, stainless steel, or aluminum alloy, etc. The tight fit between the fixing plate 4 and the mounting groove 7 and the optimized material selection together improve the overall performance of the engine end cover. This design not only enhances the rigidity and durability of the end cover but also improves the operating efficiency and reliability of the bearings and other components.

[0034] Please refer to Figure 3 , Figure 4 and Figure 6 , as an embodiment of the present utility model, mounting holes 12 are respectively provided at the four corners of the fixing plate 4, and threaded holes 13 adapted to the mounting holes 12 are provided at the four corners of the mounting groove 7.

[0035] In the above-described solution, the mounting holes 12 provided at the four corners of the fixing plate 4 and the threaded holes 13 at the four corners of the mounting groove 7 are precisely corresponding in position and size. This design ensures that the fixing plate 4 can be accurately mounted on the mounting groove 7 without misalignment or deviation during installation. The design of the mounting holes 12 and the threaded holes 13 is mainly to firmly connect the fixing plate 4 to the mounting groove 7 through bolts or other fasteners. After the bolt passes through the mounting hole 12 of the fixing plate 4, it is screwed into the threaded hole 13 of the mounting groove 7, thereby achieving the stable fixation of the fixing plate 4. By firmly connecting the fixing plate 4 to the mounting groove 7, the stable installation and long-term use effect of the fixing plate 4 are ensured, which can significantly improve the stability of the engine end cover or related components.
