Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and in particular to a compressor bracket structure for a new energy light truck. Background Art

[0002] The pure electrification of the automotive industry is an irreversible trend, and commercial vehicles such as light trucks are also gradually electrified. As light trucks have strict requirements for motor and electronic control, the use of electric compressors is inevitable, and lightweighting of automobiles has become the goal pursued by major automakers. Due to different power forms or arrangements, the compressor affects the design and development of the mounting bracket, and the bracket strength needs to meet the requirements. According to the layout position of the electric compressor on the chassis crossbeam, the mounting bracket is matched. Since the current market compressor is installed laterally according to the VDA point installation angle, the mounting bracket cannot be universal. It is necessary to design a bracket structure that can adapt to the lateral installation of the compressor. However, the current bracket structure is mainly a sheet metal bracket. However, since the compressor needs to be installed laterally, the strength requirements of the bracket structure are relatively high. When the cantilever of the sheet metal bracket is too long, it cannot meet the use requirements. In order to ensure the support strength, a casting bracket is currently used, but the casting bracket cannot meet the lightweight design requirements of the automobile due to its large weight. Therefore, this application urgently needs to provide a compressor bracket structure that is light in weight, high in strength, and can be adapted to the lateral installation of the compressor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a new energy light truck compressor bracket structure which is light in weight, high in strength and adaptable to lateral installation of the compressor.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a new energy light truck compressor bracket structure, including a bracket bottom plate and a bracket side arc plate formed by injection molding at one time,

[0005] The bracket bottom plate is used to be fixedly connected to the chassis crossbeam, and the surface of the bracket bottom plate is provided with bracket mounting holes;

[0006] The bracket side arc plate is used for lateral installation of the compressor, and the bracket side arc plate is arranged at one end of the bracket bottom plate, and a compressor installation space is formed on the inner side of the bracket side arc plate and above the bracket bottom plate; the bracket side arc plate is bent from one side end of the bracket bottom plate toward the upper side away from the bracket bottom plate, and then bent toward the upper side close to the bracket bottom plate, and the inner arc surface of the bracket side arc plate is arranged with a plurality of bolt mounting feet for mounting the compressor, and the bolt mounting feet are provided with threaded mounting holes, and the thickness of the bracket side arc plate gradually decreases from bottom to top.

[0007] As a preferred technical solution, there are three threaded mounting holes, and the axes thereof are all arranged horizontally, so as to be respectively adapted to be connected with the upper part, the lower part and the side part of the compressor.

[0008] As a preferred technical solution, a reinforcement groove is provided on the outer surface of the bracket side arc plate, and the reinforcement groove extends downward from the top end of the bracket side arc plate to the bracket bottom plate.

[0009] As a preferred technical solution, the bracket mounting hole is connected to the chassis crossbeam through a shock absorbing structure.

[0010] As a preferred technical solution, the shock-absorbing structure includes a rubber outer sleeve installed in the bracket mounting hole, a metal inner sleeve installed in the rubber outer sleeve, retaining rings are respectively fixed at the top and bottom ends of the metal inner sleeve, and a mounting hole for installing screws is provided in the metal inner sleeve.

[0011] Due to the adoption of the above technical scheme, the beneficial effects of the utility model are as follows: the utility model adopts a plastic one-piece molding design, the compressor is rigidly connected to the bracket by bolts, and then the bracket is connected to the chassis crossbeam, and its structure is reliable and effectively solves the NVH problem; due to the three-point VDA point arrangement of the electric compressor, its upper mounting point is far away from the chassis crossbeam, and the ordinary sheet metal bracket cantilever is too long, which will cause the bracket to be insufficient in strength, so a new structure is adopted and the material is replaced with plastic to achieve weight reduction, ensure the strength of the bracket, and optimize the rigid body mode of the bracket.

[0021] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0022] like Figures 1 to 4 As shown, a new energy light truck compressor bracket structure includes a bracket bottom plate 10 and a bracket side arc plate 20 formed by injection molding at one time. The bracket bottom plate 10 is used to be fixedly connected to the chassis crossbeam, and the bracket side arc plate 20 is used for the lateral installation of the compressor. The bracket side arc plate 20 is arranged at one end of the bracket bottom plate 10. The bracket bottom plate 10 and the bracket side guard plate form a similar L-shaped structure. A compressor installation space is formed on the inner side of the bracket side arc plate 20 and above the bracket bottom plate 10. This bracket structure is formed by injection molding of plastic material at one time. Compared with the split splicing structure, it has a simple structure, convenient processing, high strength, and because it is made of plastic material, it is light in weight and can meet the lightweight requirements of light trucks.

[0023] See also Figure 3 In this embodiment, the bracket side arc plate 20 is a curved design, specifically: the bracket side arc plate 20 is bent from one side end of the bracket bottom plate 10 toward the upper side away from the bracket bottom plate 10, and then bent toward the upper side close to the bracket bottom plate 10. The curvature of the inner surface of the curve is adapted to the curvature of the outer surface of the compressor, see Figure 7 . The inner arc surface of the bracket side arc plate 20 is arranged with a plurality of bolt mounting feet 21 for mounting the compressor, and the bolt mounting feet 21 are provided with threaded mounting holes 22. This bending design has the following characteristics: 1. It effectively ensures the gap between the compressor body and the bracket side arc plate 20, and the width of the gap formed between the two is basically the same, which reserves space for the design of the compressor acoustic package; 2. The bending design can ensure the thread depth of the bolt mounting foot 21 within the limited boundary space, which is used to improve the installation stability of the compressor; 3. When the compressor vibrates, the matching design of the arc structure and the plastic material makes this structure have a certain buffering effect, which has a significant advantage in optimizing the rigid body mode compared to the long cantilever sheet metal structure.

[0024] In order to balance strength and lightness, the thickness of the bracket side arc plate 20 gradually decreases from bottom to top. Figure 3 Since the lower side of the bracket side guard plate is a stress concentration point, the thick lower and thin upper structure can increase the strength of the bending part while reducing the weight.

[0025] See also Figure 1 The threaded mounting holes 22 are provided with three holes and their axes are all arranged horizontally, and are used to be adapted and connected with the upper part, the lower part and the side part of the compressor respectively. Figure 6 During installation, the outer peripheral surface of the compressor corresponds to the inner arc surface of the bracket side arc plate 20, and the three screw mounting feet form a triangular support to ensure the stable installation of the compressor.

[0026] See also Figure 2 The outer surface of the bracket side arc plate 20 is provided with a reinforcing groove 23, and the reinforcing groove 23 extends downward from the top of the bracket side arc plate 20 to the bracket bottom plate 10, which reduces the weight while increasing the strength and optimizing the rigid body mode. Adding a groove on the outside can avoid adding a reinforcing structure inside, which may cause water accumulation and rust in the compressor bracket.

[0027] See also Figure 5 The surface of the bracket bottom plate 10 is provided with a bracket mounting hole 11, and the bracket mounting hole 11 is connected to the chassis cross beam through a shock absorbing structure 30. The shock absorbing structure 30 includes a rubber jacket 31 installed in the bracket mounting hole 11, and a metal inner sleeve 32 is fixedly installed in the rubber jacket 31. The top and bottom ends of the metal inner sleeve 32 are respectively fixed with retaining rings 33, and the metal inner sleeve 32 is provided with mounting holes for mounting screws. The metal inner sleeve 32 and the retaining ring 33 are used to ensure the installation and positioning between the bracket structure and the chassis cross beam. The rubber jacket 31 prevents the bracket body from directly contacting the metal structure, thereby reducing the vibration generated during the operation of the compressor from being transmitted from the compressor body to the chassis cross beam. The coordinated design of the shock absorbing structure 30, the plastic material, and the arc structure makes the present bracket structure have a better shock absorbing effect, and has a significant advantage in optimizing the rigid body mode compared with the sheet metal structure with a long cantilever.
