TECHNICAL FIELD

[0001] The utility model relates to the field of compressor installation, specifically relates to a car electric compressor mounting bracket. BACKGROUND

[0002] The electric compressor of the new energy commercial vehicle air conditioner is arranged in the front compartment to reduce the air conditioner pipeline, reduce the cost and reduce the pipeline heat loss, but the problem is that: the front compartment space of the commercial vehicle rear drive vehicle is small, if the mounting mode similar to the patent with the announcement number CN214788812U is adopted, the damping pad is vertically arranged, and the arrangement space of the electric compressor and the electric compressor mounting bracket will be limited, that is, the electric compressor mounting bracket needs to occupy more space in the vertical direction. SUMMARY

[0003] The utility model intends to provide a car electric compressor mounting bracket to meet the arrangement of the electric compressor mounting bracket in a small space.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme: a car electric compressor mounting bracket, comprising an upper support, a lower support and a damping assembly, the damping assembly is inclinedly arranged, and the upper support and the lower support are connected through the damping assembly.

[0005] The technical effect of the scheme is that the damping assembly is inclinedly arranged, the height of the mounting bracket in the vertical direction is reduced, and the arrangement of the electric compressor mounting bracket in a small space can be met.

[0006] Preferably, as an improvement, the upper support and the lower support each comprise a bending part bent towards each other, and the upper support and the lower support are connected through the bending part and the damping assembly.

[0007] The technical effect of the scheme is that the bending part is conducive to improving the strength of the upper support and the lower support, and the bent profile also plays a buffering role to a certain extent during the operation of the electric compressor.

[0008] Preferably, the damping assembly comprises a nut, a damping rubber pad and a screw rod vulcanized with the damping rubber pad, and the damping rubber pad is connected with the bending part through the screw rod and the nut.

[0009] Preferably, the free end of the bending part is provided with a U-shaped groove, and the screw rod is connected with the nut through the U-shaped groove.

[0010] The technical effect of the scheme is that the U-shaped groove is convenient for assembling the damping rubber pad and the screw rod.

[0011] Preferably, a limiting block is fixed on the screw rod and clamped in the U-shaped groove.

[0012] The technical effect of this solution is that the U-shaped groove setting also helps to limit the limit block on the screw, preventing the shock-absorbing pad from becoming twisted and weakening the shock absorption effect when the bracket is assembled without limit. The shock-absorbing pad performs the first stage of shock absorption after the electric compressor is started.

[0013] Preferably, the size of the upper support is smaller than the size of the lower support.

[0014] Preferably, the shock-absorbing pad is a waist-shaped pad.

[0015] Preferably, tubular rubber pads are provided around the lower support.

[0016] The technical advantages of this solution are: the electric compressor mounting bracket with primary vibration damping cannot effectively solve the NVH problem; the tubular rubber pad provides secondary vibration damping after the electric compressor starts; and the entire electric compressor mounting bracket does not require more space.

[0017] Preferably, the tubular rubber pad is provided with a bushing.

[0018] Preferably, the middle of both the upper and lower supports is hollowed out. Attached Figure Description

[0022] The following detailed description illustrates the specific implementation method:

[0023] The reference numerals in the accompanying drawings include: upper bracket 1, lower bracket 2, bending part 3, U-shaped groove 4, shock-absorbing pad 5, screw 6, limiting block 7, tubular pad 8, electric compressor 9.

[0024] Example 1

[0025] Example 1 is basically as shown in the appendix. Figures 1-3 As shown: Figure 2 The illustrated automotive electric compressor mounting bracket includes an upper bracket 1, a lower bracket 2, and four shock-absorbing components, such as... Figure 1 The electric compressor 9 shown is fixedly connected to the upper bracket 1 by bolts.

[0026] The upper bracket 1 and the lower bracket 2 can be made of aluminum alloy. The size of the upper bracket 1 is smaller than that of the lower bracket 2. The middle of the upper bracket 1 and the lower bracket 2 are hollow. The four edges of the upper bracket 1 are bent downward to form a bent part 3. The inner edge of the lower bracket 2 is bent upward to form a bent part 3. The bent parts 3 of the upper bracket 1 and the lower bracket 2 are arranged in parallel. The free end of the bent part 3 has a U-shaped groove 4.

[0027] The damping components include nuts and such as Figure 3 The shock-absorbing pad 5 and screw 6 are shown. The shock-absorbing pad 5 is a waist-shaped rubber pad, which is a shape that is large at both ends and small in the middle. The screw 6 is vulcanized with the shock-absorbing pad 5, and a limit block 7 is welded on the screw 6.

[0028] like Figure 2 As shown, the shock-absorbing assembly is inclined. The upper bracket 1 and the lower bracket 2 are connected to the shock-absorbing assembly through the bending part 3. Specifically, the shock-absorbing pad 5 is located between the bending parts 3, and the screw 6 passes through the U-shaped groove 4 and is threadedly connected to the nut, thereby integrating the upper bracket 1, the shock-absorbing pad 5, and the lower bracket 2 into a whole. Figure 3 The limit block 7 shown is engaged with the following: Figure 2 Inside the U-shaped groove 4 shown.

[0029] like Figure 1 , 2 As shown, tubular rubber pads 8 are provided around the lower bracket 2. Bushings are fitted on the outside of the tubular rubber pads 8. Bolts pass through the bushings to fix the lower bracket 2 and the vehicle body.

[0030] Example 2

[0031] This embodiment describes a two-stage damping structure. Since existing patents only include the upper bracket 1 and the damping component, and the upper bracket 1 is directly connected to the vehicle body through the damping component, there is only one-stage damping structure, which cannot effectively solve the problem of abnormal noise.

[0032] This solution provides a two-stage vibration damping bracket for an electric compressor, including an upper bracket 1, a lower bracket 2, and a vibration damping assembly. The upper bracket 1 and the lower bracket 2 are connected by the vibration damping assembly, and the lower bracket 2 is equipped with a rubber pad. This solution utilizes the vibration damping assembly for first-stage vibration damping after the electric compressor 9 starts, and the rubber pads for second-stage vibration damping after the electric compressor 9 starts, effectively solving the problem of abnormal noise.

[0033] Furthermore, the shock-absorbing assembly includes a nut, a shock-absorbing pad 5, and a screw 6 vulcanized with the shock-absorbing pad 5. The shock-absorbing pad 5 is connected to the upper bracket 1 and the lower bracket 2 via the screw 6 and the nut.

[0034] Furthermore, the rubber pads are located around the lower support 2, and the rubber pads are tubular rubber pads 8.

[0035] Furthermore, the tubular rubber pad 8 is provided with a bushing.

[0036] Further, the upper support 1 and the lower support 2 each comprise a bending portion 3 bent towards each other, and the damping assembly is arranged obliquely and connected with the upper support 1 and the lower support 2 through the bending portion 3.

[0037] Or further, the damping assembly is arranged vertically and directly connected with the upper support 1 and the lower support 2.

[0038] Embodiment 3

[0039] The damping support for preventing the damping rubber pad 5 from being twisted is described in the embodiment. Since the damping rubber pad 5 of the prior art is directly connected with the upper support 1 and the vehicle body through the screw rod 6, the damping rubber pad 5 is twisted in the process of tightening the nut, thereby affecting the damping effect.

[0040] The damping support provided by the scheme comprises an upper support 1 and a damping assembly, the damping assembly comprises a nut, a damping rubber pad 5 and a screw rod 6 vulcanized with the damping rubber pad 5, a limiting block 7 is fixed on the screw rod 6, the upper support 1 is provided with a U-shaped groove 4, and the limiting block 7 is clamped in the U-shaped groove 4. The U-shaped groove 4 limits the limiting block 7 on the screw rod 6, so that the damping rubber pad 5 is not limited during assembly of the support, thereby preventing the damping rubber pad 5 from being twisted and weakening the damping effect.

[0041] Further, the nut comprises a nut body and a pressing portion, and the pressing portion abuts against the upper support 1.

[0042] Further, the lower support 2 is also provided with the U-shaped groove 4 for accommodating and clamping the limiting block 7.

[0043] Further, the damping rubber pad 5 is a waist-shaped rubber pad.

[0044] Further, the upper support 1 and the lower support 2 each comprise a bending portion 3 bent towards each other, and the U-shaped groove 4 is arranged on the bending portion 3, the damping assembly is arranged obliquely and connected with the upper support 1 and the lower support 2 through the bending portion 3.

[0045] Or further, the damping assembly is arranged vertically and directly connected with the upper support 1 and the lower support 2.

[0046] The above-mentioned is only an embodiment of the utility model, and the well-known specific technical solutions and / or common knowledge in the scheme are not described in detail. It should be noted that, for those skilled in the art, without departing from the technical scheme of the utility model, a number of deformations and improvements can be made, which should also be regarded as the protection range of the utility model, and these will not affect the effect and practicability of the utility model.
