Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a shock-absorbing mounting bracket for an automotive engine mount. Background Technology

[0002] Automotive parts technology is a technical field that revolves around the design, manufacturing, and adaptation of various automotive components. It covers structural optimization, material selection, and performance improvement, aiming to ensure that parts are well-matched with the overall vehicle, thereby enhancing vehicle reliability, safety, and comfort. It is an important support for the development of the automotive industry.

[0003] A type of car engine mount shock absorber mounting bracket falls under the category of automotive parts technology. It achieves shock absorption through high-performance rubber materials, reducing the impact on the vehicle body. It is a specific application of automotive parts technology in the field of shock absorption, demonstrating the technology's role in improving vehicle performance.

[0004] However, in the existing technology, some engine mounts rely on a single rubber component for shock absorption, lacking dual synergistic effect. As a result, the force is concentrated when vibration is transmitted, making it difficult to effectively disperse and absorb energy. Consequently, the vibration has a greater impact on the vehicle body, resulting in poor driving comfort.

[0005] Therefore, a vibration damping mounting bracket for automotive engine mounts is proposed to address the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a car engine mount shock absorption mounting bracket, which aims to improve the problem that some existing engine mounts rely solely on a single rubber component for shock absorption, lacking dual synergistic effects. This results in concentrated force during vibration transmission, making it difficult to effectively disperse and absorb energy, leading to significant impact on the vehicle body and poor driving comfort.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A shock-absorbing mounting bracket for an automobile engine mount includes a base, a fixing ring fixedly connected to the inner wall of the base, a rubber ring fixedly connected to the inner wall of the fixing ring, an inner ring slidably connected to the inner wall of the rubber ring, a plurality of balls movably connected to one side of the inner wall of the rubber ring and the outer side of the inner ring, a connector fixedly connected to the outside of the balls, and a spring fixedly connected to the adjacent side of every two connectors. As a further description of the above technical solution: The inner wall of the inner ring is fixedly connected to a mounting post, and the mounting post is installed on the engine by screws. As a further description of the above technical solution: Bolts are provided on both sides of the bottom of the machine feet; As a further description of the above technical solution: The contact surfaces of the rubber ring with the fixing ring and the inner ring are all provided with anti-slip textures, which are distributed in a ring array. As a further description of the above technical solution: A buffer pad is provided at the connection between the bolt and the machine foot, and the buffer pad is a nitrile rubber buffer pad. As a further description of the above technical solution: The balls are arranged in a ring around the center of the inner ring, and the central angles between adjacent balls are equal. As a further description of the above technical solution: A damping rubber layer is filled between the inner wall of the foot and the outer wall of the fixing ring. As a further description of the above technical solution: The outer wall of the machine foot is provided with a protective coating, which is an epoxy resin protective coating.

[0008] This utility model has the following beneficial effects: In this invention, excellent vibration reduction is achieved through the dual action of "spring buffering + rubber energy absorption". Engine vibration is transmitted to the inner ring through the mounting post, causing the ball bearings to roll and compress and stretch the spring. The reverse force restricts the absorption of energy; the deformation of the rubber ring further absorbs energy, reducing the impact on the vehicle body and improving driving comfort.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 4 This utility model provides an embodiment of a car engine mount shock absorber mounting bracket, including a mount 1. The mount 1 provides the mounting base and support frame for the overall structure. A fixing ring 2 is fixedly connected to the inner wall of the mount 1. The fixing ring 2 provides a stable mounting carrier for the rubber ring 3, enhancing the connection strength of the overall structure. A damping rubber layer is filled between the inner side wall of the mount 1 and the outer side wall of the fixing ring 2. The damping rubber layer consumes vibration energy through its own viscoelastic properties, further improving the shock absorption effect. A protective coating is provided on the outer side wall of the mount 1. The protective coating is an epoxy resin protective coating. The protective coating resists the corrosion of oil and water vapor in the engine compartment, preventing the structural strength of the mount 1 from decreasing due to corrosion or wear.

[0013] A rubber ring 3 is fixedly connected to the inner wall of the fixed ring 2. The rubber ring 3 is elastic and deforms under force to absorb vibration energy and reduce vibration transmission efficiency. An inner ring 4 is slidably connected to the inner wall of the rubber ring 3. The inner ring 4 transmits the vibration of the engine to the balls 6 and the spring 8, serving as an intermediate carrier for vibration transmission. Anti-slip textures are provided on the contact surfaces of the rubber ring 3 with the fixed ring 2 and the inner ring 4. The anti-slip textures are distributed in a ring array. The anti-slip textures enhance the friction between the rubber ring 3 and the fixed ring 2 and the inner ring 4, preventing relative slippage and separation. A mounting post 5 is fixedly connected to the inner wall of the inner ring 4 and is installed on the engine by screws. The mounting post 5 transmits the vibration generated by the engine to the inner ring 4, realizing effective vibration transmission. Multiple balls 6 are movably connected to one side of the inner wall of the rubber ring 3 and the outer wall of the inner ring 4. The balls 6 are distributed in a ring along the center of the inner ring 4, and the central angle between adjacent balls 6 is equal. The ring-shaped distribution of balls 6 ensures that the inner ring 4 is subjected to balanced force when vibrating in any direction, avoiding excessive force on local structures.

[0014] The ball bearing 6 is externally fixedly connected to a connector 7, which connects the ball bearing 6 to the spring 8 to achieve force transmission. A spring 8 is fixedly connected to the adjacent side of every two connectors 7. When the spring 8 is subjected to external force, it undergoes compression or tension deformation, generating a reverse elastic force to absorb vibration energy. Bolts 9 are provided on both sides of the bottom end of the machine foot 1. The bolts 9 fix the machine foot 1 to the crossbeam of the vehicle body to ensure the installation stability of the overall structure. A buffer pad is provided at the connection between the bolt 9 and the machine foot 1. The buffer pad is a nitrile rubber buffer pad. The buffer pad buffers the vibration transmitted from the machine foot 1 to the vehicle body through its own elastic deformation, while preventing the bolt 9 from loosening.

[0015] Working principle: When the engine vibrates during operation, the vibration is transmitted to the inner ring 4 through the mounting post 5, causing the inner ring 4 to sway in multiple directions. Since the inner ring 4 is slidably connected to the inner wall of the rubber ring 3 through a ring array of balls 6, the balls 6 can roll along the inner wall of the rubber ring 3 as the inner ring 4 sways. At this time, the connecting piece 7, which is fixedly connected to the balls 6, moves synchronously.

[0016] During the movement of connector 7, the spring 8 in the corresponding direction is compressed as connector 7 moves closer, generating a reverse elastic force. Conversely, the spring 8 in the diagonal direction is stretched as connector 7 moves further away, also generating a reverse force. These two forces restrain each other, and the elastic deformation of spring 8 absorbs some vibration energy, initially buffering the swaying amplitude of inner ring 4. Meanwhile, the rubber ring 3 itself is elastic and deforms under the rolling action of ball 6 and the compression of inner ring 4, further absorbing vibration energy and reducing vibration transmission efficiency.

[0017] Although the epoxy resin protective coating on the outer wall of the engine mount 1 does not directly participate in the shock absorption process, it can resist the corrosion of oil and water vapor in the engine compartment, prevent the engine mount 1 from losing structural strength due to corrosion or wear, and indirectly ensure the long-term stable operation of the overall shock absorption system.

[0018] Ultimately, through the elastic buffering of spring 8, the deformation energy absorption of rubber ring 3, and the stable cooperation of various components, most of the vibration energy generated by the engine is consumed, and the vibration transmitted to the vehicle body is greatly reduced, achieving the shock absorption effect.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
