Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology for new energy vehicles, specifically a vibration reduction bracket for electric scroll compressors in new energy vehicles. Background Technology

[0002] During use, electric scroll compressors in new energy vehicles will generate low-frequency vibrations and noise. To improve passenger comfort, vibration damping pads are usually installed on the bracket of the electric scroll compressor to reduce noise and vibration.

[0003] However, in practice, the vibration damping pads bear the weight of the support and the pump. Long-term heavy pressure reduces the elasticity of the damping pads. When the elasticity decreases, the pads' ability to absorb and disperse vibration energy weakens, leading to a reduction in vibration damping effect. Therefore, we propose a vibration damping support for electric scroll compressors in new energy vehicles. Utility Model Content

[0005] In view of the problems existing in the above and / or existing vibration damping brackets for electric scroll compressors in new energy vehicles, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A vibration damping bracket for an electric scroll compressor in a new energy vehicle includes a damping plate, a fixed base, and a buffer connection mechanism, wherein the damping plate and the fixed base are connected by the buffer connection mechanism.

[0020] Example

[0021] Please refer to the following: Figures 1 to 4 This embodiment provides a vibration damping bracket for electric scroll compressors in new energy vehicles. Applied to the installation and fixing of electric scroll compressors in new energy vehicles, it solves the problem that existing vibration damping brackets rely on a single damping pad to bear weight, leading to decreased elasticity and weakened vibration damping effect due to long-term heavy pressure. Through distributed support and multiple buffer designs, the bracket extends the service life of the vibration damping components while ensuring a continuous and stable vibration damping and noise reduction effect. The bracket includes a damping plate 1, a fixing base 2, and a buffer connection mechanism 3. The damping plate 1 supports the electric scroll compressor, the fixing base 2 connects to the vehicle body to provide an installation foundation, and the buffer connection mechanism 3 achieves elastic connection and vibration buffering between the two.

[0022] Specifically, the mounting base 2 includes a mounting plate 6 and a support frame 7. The mounting plate 6 is used to fix and connect to the car body. The support frame 7 is fixedly installed at both ends of the mounting plate 6 and extends vertically to provide installation support for the buffer connection mechanism 3. The buffer connection mechanism 3 includes a constraint frame 8 fixedly installed on the support frame 7. The constraint frame 8 has a frame structure and a shock-absorbing pad 9 is installed inside. The shock-absorbing pad 9 can be made of elastic material such as rubber or silicone and has good vibration absorption capacity.

[0023] The damping plate 1 includes a plate body 4 and an end plate 10. The plate body 4 is used to place and fix the electric scroll compressor. The end plate 10 is fixedly set at both ends of the plate body 4, corresponding to the position of the constraint frame 8. The bottom surface of the end plate 10 is in close contact with the top surface of the damping pad 9. The damping pad 9 forms an elastic support for the damping plate 1, which initially absorbs the low-frequency vibration generated by the electric scroll compressor during operation. It can reduce the vibration force transmitted to the vehicle body to a certain extent and reduce noise at the same time.

[0024] A plurality of support rods 5 are fixedly installed on the bottom surface of the end plate 10 of the damping plate 1. The support rods 5 extend vertically, are inserted into and pass through the constraint frame 8, and extend to the bottom of the constraint frame 8. A plurality of sleeves 12 corresponding to the support rods 5 are fixedly installed on the bottom surface of the constraint frame 8. The sleeves 12 extend vertically, and the support rods 5 are inserted into the sleeves 12 and slide to fit the sleeves 12. The sleeves 12 provide guidance for the vertical movement of the support rods 5 and prevent the support rods 5 from shifting during vibration. A first clamp 13 is fitted on the outer wall of the support rod 5. The first clamp 13 is located inside the sleeve 12 and adopts an elastic structure. Its inner wall fits against the outer wall of the support rod 5, and its outer wall fits against the inner wall of the sleeve 12. When the support rod 5 moves up and down due to vibration, the first clamp 13 absorbs part of the vibration energy through elastic deformation, while limiting the radial sway of the support rod 5 and improving the structural stability.

[0025] On both sides of the top of the mounting plate 6 of the fixed base 2, several connecting rods 11 corresponding to the support rod 5 are fixedly installed. The connecting rods 11 extend vertically, and their top ends are inserted into the interior of the support rod 5 and slidably fitted with the support rod 5. A second sleeve 14 is fixedly installed inside the support rod 5. The second sleeve 14 adopts an elastic structure, and its inner wall is tightly fitted with the outer wall of the connecting rod 11, while its outer wall is fixedly connected to the inner wall of the support rod 5. The cooperation between the connecting rod 11 and the support rod 5 forms an auxiliary support, distributing part of the weight of the electric scroll compressor to the connecting rod 11 and the fixed base 2, preventing the shock-absorbing pad 9 from bearing the entire weight alone, reducing the long-term pressure loss of the shock-absorbing pad 9, and extending its service life. At the same time, the second sleeve 14 buffers the vibration transmission between the support rod 5 and the connecting rod 11 through elastic deformation, avoiding the direct transmission of vibration through rigid contact, and further improving the vibration reduction effect.

[0026] The opening edge of the second sleeve 14 is provided with a flange 15, which extends outward in the horizontal direction and fits against the bottom end face of the support rod 5, enhancing the connection stability between the second sleeve 14 and the support rod 5 and preventing the second sleeve 14 from falling out of the support rod 5 during vibration. The inner wall of the constraint frame 8 abuts against the side of the end plate 10 through the shock-absorbing pad 9, and the contact between the two is tighter, making the shock absorption and support effects more prominent.

[0027] In practical applications, the electric scroll compressor is fixedly mounted on the body 4 of the damping plate 1, and the mounting plate 6 is fixedly connected to the car body. When the compressor generates low-frequency vibrations during operation, the vibrations are first transmitted to the damping plate 1. The end plate 10 of the damping plate 1 compresses the damping pad 9, and the damping pad 9 absorbs some of the vibration energy through elastic deformation. At the same time, the damping plate 1 drives the support rod 5 to move up and down. The first sleeve 13 on the outer wall of the support rod 5 undergoes elastic deformation within the sleeve 12, further buffering the vibration. The second sleeve 14 inside the support rod 5 cooperates with the connecting rod 11 to absorb the vibration transmitted along the axial direction of the support rod 5 through elastic deformation, preventing the vibration from being directly transmitted to the fixed seat 2 and the car body. This effectively weakens the vibration transmission and reduces noise. At the same time, the auxiliary support of the connecting rod 11 and the support rod 5 disperses the gravity, reduces the compressive load on the damping pad 9, and prevents its elasticity from decreasing due to long-term heavy pressure, ensuring the continuity of the vibration reduction effect.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
