Description

TECHNICAL FIELD

[0001] The utility model relates to a support technical field of automobile engine, more specifically, it relates to a side-mounted damping support of engine. BACKGROUND

[0002] In the early engine mounting design, the engine usually adopts a relatively simple and direct mounting mode, for example, rigid connection, which directly fixes the engine on the frame or the vehicle body structure, although the structure is simple and the cost is low, but there are obvious disadvantages. Since the engine will produce a lot of vibration and noise during operation, rigid connection will make these vibrations and noises pass to the frame and the vehicle body without buffering, thereby affecting the comfort and stability of the whole vehicle. The driver and passenger can obviously feel strong vibration and noise, and long-term stay in such an environment will greatly reduce the driving experience, and even may cause physical fatigue and discomfort. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims at providing a side-mounted damping support of engine with good damping effect, good durability and strong versatility.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a side-mounted damping support of engine, comprising a base, a damping module is arranged in the base, the damping module comprises a hydraulic damper arranged in the base and an elastic rubber embedded in the base in a cross layout, and a fixing assembly is further arranged on the base for stably mounting the base in the vehicle.

[0005] The utility model is further provided as follows: the fixing assembly comprises a connecting part extending from one end of the base and provided with a plurality of mounting holes, and a mounting sheet connected with the damping module.

[0006] The utility model is further provided as follows: the mounting sheet is an ear-shaped structure with a hole position, which can be fixed by additional bolts or screws to increase the mounting stability of the support.

[0007] The utility model is further provided as follows: the length of the short side of the mounting sheet is 1 / 4-1 / 3 times the length of the long side.

[0008] The utility model is further provided as follows: the base is further provided with a reinforcing rib for reinforcing the structure.

[0009] The utility model has the beneficial effects that:

[0010] 1. The engine side-mounted damping support adopts a damping module with a cross layout of hydraulic dampers and elastic rubber. The hydraulic dampers can generate damping force through the flow of internal liquid when the engine vibrates, effectively absorbing and dissipating vibration energy, especially for high-frequency vibrations. The elastic rubber has good elastic deformation ability, which can buffer and disperse vibrations, and has a significant damping effect on low-frequency vibrations. The cross layout of the two complements each other, forming a comprehensive and multi-level damping system, which can more efficiently reduce the vibration and noise transmitted from the engine to the vehicle body, greatly improving the comfort of driving and riding. The fixing assembly provided on the base can stably install the base in the vehicle, ensuring the reliable connection between the damping support and the vehicle structure, preventing the damping support from loosening or shifting due to vibration, bumping, and other factors during vehicle driving.

[0011] 2. The connecting part in the fixing assembly extends from one end of the base and is provided with several mounting holes, making the damping support have high flexibility during installation. Through these mounting holes, connecting parts can be connected with specific parts of the vehicle using bolts and other connecting parts. The installation method is simple and direct, and the installation position and requirements of different vehicle models may differ. The provision of multiple mounting holes can adapt to the adjustment of various installation angles and positions, facilitating the installation and adaptation on different vehicles, greatly shortening the installation time and improving the assembly efficiency on the production line. The mounting piece connected with the damping module provides precise positioning and support for the installation of the damping module. The mounting piece can stably fix the damping module in the appropriate position, ensuring the accurate relative position between the damping module and the engine and the vehicle structure, which helps to ensure that the damping module can fully play its damping role and avoid a decrease in damping effect due to inaccurate installation position.

[0012] 3. The mounting piece is an ear-shaped structure with a hole position, which greatly enhances the stability of the support installation. The ear-shaped structure can provide a larger contact area and mounting force point, so that the bolt or screw can more evenly distribute stress when fastened. Under the strong vibration generated by the engine operation and the bumping impact during vehicle driving, this multi-directional fixing method can effectively prevent the support from loosening and shifting, ensuring that the engine side-mounted damping support is always stably installed on the vehicle and ensuring the continuous and effective play of the damping function. The length of the short side of the mounting piece is 1 / 4-1 / 3 times the length of the long side, which has enough strength to withstand tension and pressure, and also maintains a certain flexibility to adapt to different installation angles and slight deformation. The long side provides a larger installation span, facilitating connection and fixation with the vehicle structure, while the short side enhances the overall stability and torsional resistance of the mounting piece while ensuring compact structure, further improving the firmness of the entire support installation.

[0013] 4. The reinforcing ribs provided on the base can significantly enhance the structural strength and rigidity of the entire damping support. During the operation of the engine, the damping support needs to withstand a large vibration load and various forces from the engine. The reinforcing ribs, like bones, provide additional support and reinforcement for the support, enabling it to better resist deformation and damage, and helping to ensure that the damping support maintains a stable structural form during long-term use, thereby continuously and effectively playing a damping role.

[0017] Reference Figs. 1 to 2 Further description of the embodiments of the utility model.

[0018] For ease of description, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to describe the relationship of one element or feature to another element or feature shown in the drawings. It should be understood that, in addition to the orientation shown in the drawings, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the drawing is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "below" can include both upward and downward orientations. The device can be positioned in other ways (rotated 90 degrees or positioned in other orientations), and the spatial relative description used herein can be interpreted accordingly.

[0019] Moreover, relational terms such as "first" and "second" and the like are used only to distinguish one from another of a same name, and do not necessarily require or imply any such actual relationship or order between the parts.

[0020] Figs. 1 to 2The engine side mounting shock absorber shown comprises a base 1, a damping module is arranged in the base 1, the damping module comprises a hydraulic damper 2 arranged in the base 1 and an elastic rubber arranged in the base 1 in a cross layout and embedded in the base 1, the hydraulic damper 2 can generate damping force through the flow of internal liquid when the engine vibrates, effectively absorbing and dissipating vibration energy, especially having excellent suppression effect on high-frequency vibration. The elastic rubber has good elastic deformation capacity and can buffer and disperse vibration, and has significant damping effect on low-frequency vibration. The cross layout of the two can complement each other to form a comprehensive and multi-level damping system, which can more efficiently reduce the vibration and noise transmitted from the engine to the vehicle body and greatly improve the comfort of driving and riding. The elastic rubber can first play a preliminary buffering role in the strong impact vibration generated at the moment of engine starting, and then the hydraulic damper further absorbs and stabilizes the vibration; the hydraulic damper can accurately suppress the high-frequency micro-vibration during stable operation of the engine to ensure the stability of the damping effect during the whole process. The base 1 is further provided with a fixing assembly, which can stably install the base 1 in the vehicle to ensure the reliable connection between the damping bracket and the vehicle structure and prevent the damping bracket from loosening or shifting due to vibration, bumping and other factors during vehicle driving.

[0021] The fixing assembly comprises a connecting part 4 extending from one end of the base 1 and provided with a plurality of mounting holes 3, and a mounting sheet 5 connected with the damping module, the connecting part 4 extends from one end of the base 1 and is provided with a plurality of mounting holes 3, so that the damping bracket has high flexibility during installation. Through the mounting holes 3, the connecting part 4 can be connected with a specific part of the vehicle using bolts and other connecting parts, and the installation method is simple and direct. The installation position and requirement of different vehicle models may be different, and the plurality of mounting holes 3 can adapt to the adjustment of various installation angles and positions, facilitating the adaptive installation on different vehicles, greatly shortening the installation time and improving the assembly efficiency on the production line. The mounting sheet 5 connected with the damping module provides precise positioning and support for the installation of the damping module, the mounting sheet 5 can stably fix the damping module at the appropriate position, ensuring the accurate relative position between the damping module and the engine and the vehicle structure, which helps to ensure that the damping module can fully play its damping effect and avoid the decrease of damping effect due to inaccurate installation position.

[0022] The mounting holes 3 can also have a hexagonal structure to form a hexagonal hole array, which has excellent stress dispersion capacity. When the vibration of the engine is transmitted to the base 1, the hexagonal hole array can uniformly disperse the stress to the entire connecting surface, avoiding stress concentration in a certain point or area. This not only can reduce the deformation and damage of the base 1 due to excessive local stress, but also can improve the stability of the connection between the base 1 and the engine, ensuring that the damping bracket can better play the damping effect.

[0023] The mounting piece 5 is an ear-shaped structure with a hole position, which greatly enhances the stability of the bracket installation through additional bolts or screws, and the ear-shaped structure can provide a larger contact area and mounting force point, so that the bolts or screws can be more evenly dispersed when fastened. Under the strong vibration generated by the engine operation and the bumping impact during vehicle driving, this multi-directional fixing method can effectively prevent the bracket from loosening and shifting, ensuring that the engine side-mounted shock-absorbing bracket is always stably installed on the vehicle, and ensuring the continuous and effective play of the shock-absorbing function.

[0024] Further, when the length of the short side of the mounting piece 5 is less than 1 / 4 of the length of the long side, the overall structural strength is greatly reduced, and the mounting piece 5 is prone to deformation or even breakage under stress, especially at the bolt or screw fixing position, the stress concentration phenomenon is more obvious, thereby affecting the installation stability of the entire shock-absorbing bracket, which may cause the shock-absorbing bracket to loosen, thereby greatly reducing the shock-absorbing effect of the engine, and even threatening the safety of the vehicle; when the length of the short side of the mounting piece 5 is greater than 1 / 3 of the length of the long side, it occupies too much space, which may interfere with other components in the engine compartment, and also increases the material usage of the mounting piece 5, thereby increasing the weight of the entire shock-absorbing bracket, and the long short side may cause some parts of the mounting piece 5 to bear excessive stress, while other parts bear less stress; therefore, the length of the short side of the mounting piece 5 is 1 / 4-1 / 3 of the length of the long side, which has sufficient strength to withstand tension and pressure, and also has a certain flexibility to adapt to different installation angles and slight deformation. The long side provides a larger installation span, facilitating connection and fixation with the vehicle structure, and the short side enhances the overall stability and torsional resistance of the mounting piece 5 while ensuring compact structure, further improving the firmness of the entire bracket installation.

[0025] The base is also provided with a reinforcing rib 6 for strengthening the structure, which can significantly enhance the structural strength and rigidity of the entire shock-absorbing bracket. During engine operation, the shock-absorbing bracket needs to withstand large vibration loads and various forces from the engine. The reinforcing rib 6 provides additional support and reinforcement for the bracket, enabling it to better resist deformation and damage, and helping to ensure that the shock-absorbing bracket maintains a stable structural form during long-term use, thereby continuously and effectively playing a shock-absorbing role.

Any changes and substitutions within the technical scheme of the present application made by those skilled in the art should be included within the protection scope of the present application.
