As a preferred scheme, the high-density reinforcing ribs are in a shape like a Chinese character 'mi'.

As a preferable scheme, the hollow area in the middle of the bracket body is 1/3-1/5 of the area of the bracket body for installing the high-density reinforcing ribs.

Preferably, the height of the mounting column is not less than the thickness of the bracket body.

As a preferred scheme, be equipped with four connecting seats on the support body, every connecting seat all corresponds the corner of support body.

As a preferable scheme, the number of the mounting columns is at least three, and the mounting columns are respectively adjacent to the positions of different connecting seats.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model has the advantages of simple overall structure, reasonable in design, light in weight and intensity are high, and the practicality is strong, and the NVH performance is high.

Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

The purpose of this embodiment is in order to solve among the prior art the lower, relatively poor problem of whole car NVH effect of electric compressor support universalization rate, provides a novel electric compressor support.

Specifically, referring to fig. 1 to 4, the bracket of the present embodiment may be pre-assembled on the electric vehicle and then the electric compressor may be fixed to the bracket. The whole aluminum alloy structure that is of support of this embodiment, including support body, connecting seat 1 and erection column. Wherein, the support body is unique sets up to the font of returning, and the structure of the font of returning can ensure self stability on the one hand, can also ensure its and the installation stability of corresponding spare part device etc. on the other hand can also alleviate the weight of whole support, and the design is very ingenious. The frame of support body mainly is two inside and outside mouth shape frames, is vacant fretwork 5 in the inside mouth shape frame promptly, for guaranteeing that it does not influence support stability to, also in order to reduce the manufacturing and use degree of difficulty, support body middle part fretwork area is 1/3 ~ 1/5 for support body installation high density strengthening rib area is the best. A plurality of high-density reinforcing ribs 6 in a shape like a Chinese character 'mi' are arranged between the two square-shaped frames, the high-density reinforcing ribs 6 can be made of high-strength polymer nano materials or aluminum alloy materials directly to ensure the strength of the bracket, and the specific arrangement mode of the high-density reinforcing ribs can be that single-layer reinforcing ribs are directly filled between the two square-shaped frames or multi-layer reinforcing ribs are filled between the two square-shaped frames in a staggered and superposed mode; in addition, a fixing plate may be disposed between the two frame members, and then the fixing plate may be disposed between the two frame members on both sides of the fixing plate. Of course, when the whole bracket has larger volume, the high-density reinforcing ribs 6 can be adjusted according to the requirement.

Four corners of the support body are respectively provided with a connecting seat 1, the outer side of the connecting seat is fixed on the mouth-shaped frame, and the high-density reinforcing ribs 6 adjacent to the connecting seat are fixed on the connecting seat 1, so that the stability of the connecting seat on the support body can be ensured. Connecting seat 1 mainly used and electric automobile power spare part (electric automobile's kit, this application does not improve it, and it is unnecessary to give redundant details here) meet mutually, and is great in order to prevent the motor compressor rotational speed, causes whole car NVH effect relatively poor, be equipped with the shock attenuation vulcanized rubber 3 that encircles connecting seat 1 on the support body, after on this embodiment support pre-installation electric automobile power spare part, shock attenuation vulcanized rubber 3 pastes with electric automobile power spare part mutually, so, can play the cushioning effect. Be equipped with bush 4 between shock attenuation vulcanized rubber 3 and the connecting seat, so multiplicable shock attenuation vulcanized rubber 3's installation stability to play the effect that protection shock attenuation vulcanized rubber 3 reduces wearing and tearing. Here, the structure of the fretwork and the strengthening rib of support body because its non-solid structural design can also effectively avoid high frequency resonance, can further play certain cushioning effect.

In particular, the present embodiment is provided with three mounting posts 2, each of which is adjacent to a different connecting seat 1, so that the mounting stability of the electric compressor can be increased, and more types of electric compressors can be adapted (for example, the electric compressor with a three-point mounting structure, and the conventional brackets at two mounting points on the market cannot be adapted). The height of the mounting column 2 is not less than the thickness of the bracket body, and the mounting stability of the electric compressor can be further ensured. Be equipped with the internal thread hole on the erection column 2, be used for with electric compressor bolted connection to ensure can fix electric compressor.

The electric compressor support of this embodiment is through improving its structure, the material is optimized, and each part sees the improvement point alone less, nevertheless discovers after probating, because each part structure synergism, installation stability, the promotion NVH performance that can effectual increase electric compressor to still can increase its suitability, the practicality is strong.
