Description

Technical Field

[0001] This utility model belongs to the field of compressor mounting brackets, specifically relating to a double-layer vibration damping bracket structure for an electric compressor. Background Technology

[0002] Automotive electric compressors are typically mounted on the vehicle's base. However, the vibrations from vehicle movement can affect the compressor's operation, or the vibrations generated by the compressor can be transmitted to the vehicle, causing noise. Therefore, the compressor needs to be mounted to the base using a vibration damping device.

[0003] Common vibration damping devices typically involve placing a support frame between the compressor and the base, with rubber damping pads between the support frame and the base, and then tightening them with bolts. This method of vibration damping can only achieve vertical vibration damping through the rubber damping pads, and it has shortcomings in both the damping dimension and the damping effect. Utility Model Content

[0004] The purpose of this utility model is to provide a double-layer vibration damping support structure for an electric compressor in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A double-layer vibration damping bracket structure for an electric compressor includes a first bracket and a second bracket. The first bracket is provided with a plurality of first vibration damping parts that dampen vibration in the vertical direction. A plurality of second vibration damping parts that dampen vibration in the inclined direction are provided between the first bracket and the second bracket. The second vibration damping part includes a dumbbell-shaped second vibration damping pad. The second bracket has an inclined through hole that mates with the second vibration damping pad. The through hole has a side opening for the narrow middle portion of the second vibration damping pad to enter. The second vibration damping pad is pressed between the first bracket and the second bracket by a fixing member.

[0007] As a further optimization of this utility model, the first vibration damping part is used to connect the base. The first vibration damping part includes a first vibration damping pad and a fixing bolt. The fixing bolt passes through the first vibration damping pad to press the first support and the base together with the first vibration damping pad. This solution specifically proposes a first vibration damping part for the vertical direction. Since the vertical direction is the most frequent during vehicle operation, the first vibration damping part is in the vertical direction.

[0008] As a further optimization of this utility model, the second bracket is provided with a plurality of connecting ears for connecting the compressor body.

[0009] As a further optimization of this utility model, the second bracket is provided with a first bending part and a second bending part, and through holes are opened on the first bending part and the second bending part. There are two first bending parts, which face the first direction and the second direction respectively, and one second bending part, which faces the third direction. In this solution, the first, second and third directions are different and are all non-vertical inclined directions, which can absorb horizontal vibrations.

[0010] As a further optimization of this utility model, the first bracket is provided with connecting ends that are respectively parallel to the first bend and the second bend, so as to facilitate the fixation of the second vibration damping part on the second bracket.

[0011] As a further optimization of this utility model, the fixing component includes a nut, a washer, and a bolt. The bolt passes through the connection end between the second vibration damping pad and the first bracket. The bolt is pressed against one end of the second vibration damping pad by the washer, and the nut is pressed against the connection end of the first bracket. In this solution, the second vibration damping pad is fixed between the first bracket and the second bracket by a specifically designed fixing component.

[0012] As a further optimization of this utility model, an annular groove is provided in the middle of the outer surface of the second vibration damping pad, so that the second vibration damping pad is dumbbell-shaped. The width of the annular groove along the axial direction of the second vibration damping pad is greater than the thickness of the through hole. The second vibration damping pad is set in this shape so that when the fixing member presses the second vibration damping pad, the wide ends of the second vibration damping pad are squeezed towards the middle, and the diameter of the second vibration damping pad at the annular groove expands and presses against the inner wall of the through hole to prevent random shaking.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a double-layer vibration damping bracket. The first bracket and the first damping part absorb vertical vibrations, while the inclined second damping part absorbs horizontal vibrations. The second bracket has buffer space in any horizontal direction by using a through hole with side openings to cooperate with a dumbbell-shaped second damping pad. Furthermore, the two ends of the second damping pad press against the inclined surface outside the through hole, which helps to deform and absorb vibrations. Attached Figure Description

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-6 As shown, a double-layer vibration damping bracket structure for an electric compressor includes a first bracket 1 and a second bracket 2. The first bracket 1 is provided with a plurality of first vibration damping parts 3 that dampen vibration in the vertical direction. A plurality of second vibration damping parts 4 that dampen vibration in the inclined direction are provided between the first bracket 1 and the second bracket 2. The second vibration damping part 4 includes a dumbbell-shaped second vibration damping pad 41. The second bracket 2 is provided with an inclined through hole 204 that cooperates with the second vibration damping pad 41. The through hole 204 has a side opening for the narrow middle part of the second vibration damping pad 41 to enter. The second vibration damping pad 41 is pressed between the first bracket 1 and the second bracket 2 by a fixing member.

[0025] This solution uses a double-layer vibration damping bracket. The first bracket 1 and the first damping part 3 absorb vertical vibrations, while the inclined second damping part 4 absorbs horizontal vibrations. The second bracket 2 has buffer space in any horizontal direction, and the two ends of the second damping pad 41 press against the inclined surface outside the through hole, which helps to deform and absorb vibrations.

[0026] It should be noted that the vibration damping pad is made of rubber material, which has viscoelasticity. When subjected to force, it undergoes both elastic deformation and viscous flow. When the rubber deforms, the friction between the molecular chains causes some mechanical energy to be converted into heat energy, absorbing vibration energy and producing a damping effect.

[0027] The first vibration damping part 3 is used to connect to the base 6. The first vibration damping part 3 includes a first vibration damping pad 31 and a fixing bolt 32. The fixing bolt 32 passes through the first vibration damping pad 31, causing the first bracket 1 and the base 6 to press the first vibration damping pad 31 tightly. This solution specifically proposes a first vibration damping part 3 for the vertical direction, since vertical vibrations are most frequent during vehicle operation; therefore, the first vibration damping part 3 is vertical. The second bracket 2 is provided with several connecting ears 203 for connecting to the compressor body 5.

[0028] The second support 2 is provided with a first bending portion 201 and a second bending portion 202. A through hole 204 is formed in the first bending portion 201 and the second bending portion 202. There are two first bending portions 201, facing the first and second directions respectively, and one second bending portion 202, facing the third direction. In this design, the first, second, and third directions are all different and are all non-vertical inclined directions, capable of absorbing horizontal vibrations. The specific details of these three directions are as follows: Figure 5 As shown, the two first bending portions 201 bend towards each other, that is, bend towards the center, forming the first direction and the second direction, while the second bending portion 202 bends towards the direction of the first bending portion 201.

[0029] The first bracket 1 is provided with connecting ends that are respectively parallel to the first bend 201 and the second bend 202, which are used to facilitate the fixing of the fasteners on the second bracket 2.

[0030] The fasteners include a nut 44, a washer 45, and a bolt 43. The bolt 43 passes through the connection end between the second damping pad 41 and the first bracket 1. The bolt 43 is pressed against one end of the second damping pad 41 by the washer 45, and the nut 44 is pressed against the connection end of the first bracket 1. In this solution, the second damping pad 41 is fixed between the first bracket 1 and the second bracket 2 by the specially designed fasteners.

[0031] A ring groove 42 is provided in the middle of the outer surface of the second vibration damping pad 41, so that the second vibration damping pad 41 is dumbbell-shaped. The width of the ring groove 42 along the axial direction of the second vibration damping pad 41 is greater than the thickness of the through hole 204. The second vibration damping pad 41 is set in this shape so that when the fixing member presses the second vibration damping pad 41, the wide parts at both ends of the second vibration damping pad 41 are squeezed towards the middle, and the diameter of the second vibration damping pad 41 at the ring groove 42 expands and presses against the inner wall of the through hole 204 to prevent it from shaking randomly.

[0032] The specific implementation method is as follows: when vertical vibration occurs, the first damping part 3 performs vibration damping;

[0033] When horizontal vibration occurs, Figure 4Taking the left-right direction from a top-down view (let's call it the X direction), since the narrow middle section of the second damping pad 41 is fixed by the through hole 204, there is a horizontal buffer space between the first bracket 2 and the fixing member. During vibration, the second bracket 2 and the second damping pad 41 undergo relative displacement in the X direction. This displacement causes the second bent portion 202 to press against the wide sections at both ends of the second damping pad 41 for buffering and vibration reduction. Similarly, in Figure 4 In the top-down direction (set as Y direction), the first bend 202 presses the wide sections at both ends of the second damping pad 41 to buffer and dampen vibration.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
