Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts technology, and in particular to a compressor bracket assembly. Background Technology
[0002] The automotive air conditioning compressor is the core component of the air conditioning refrigeration system, and it is fixed in the engine compartment by a compressor bracket assembly. Due to the compact space and complex layout of the engine compartment, the design of the compressor bracket has a significant impact on space utilization, assembly efficiency, and the overall NVH performance of the vehicle.
[0003] Relevant prior art, such as the Chinese patent application "Automotive Air Conditioner Compressor Bracket", application number: CN201210471566.3, discloses a bracket body, the bottom of which is provided with four protrusions, namely protrusion one, protrusion two, protrusion three, and protrusion four, each of which has a through compressor mounting hole; the front of the bracket body is also provided with four protrusions, namely protrusion five, protrusion six, protrusion seven, and protrusion eight, and each of which has a generator connection hole; all protrusions, compressor mounting holes, and generator connection holes are integrally formed and are made of cast aluminum.
[0004] In existing technology, the compressor bracket and the air conditioner compressor are usually connected vertically, meaning the compressor axis is perpendicular to the bracket mounting surface, and the bottom of the compressor is rigidly connected to the bracket using bolts. This structure has the following drawbacks:
[0005] Firstly, the vertical connection method requires sufficient operating space between the bottom of the compressor and the bracket to accommodate bolts, washers, and installation tools, resulting in an excessively large overall assembly height, which is difficult to meet the layout requirements of a miniaturized and lightweight engine compartment. Secondly, traditional brackets lack effective limiting design, and during compressor operation, vibration may cause excessive displacement of the rubber bushing, which in turn affects the parallelism between the pulley and the engine crankshaft, producing abnormal noise or even damage. Therefore, this application proposes a compressor bracket assembly to solve the above problems. Utility Model Content
[0006] The technical problem to be solved by this application is to provide a compressor bracket assembly, which adopts a triangular side-mounted bracket to achieve lightweight and flexible compressor fixation in a compact space.
[0007] The technical solution adopted in this application is as follows: a compressor bracket assembly, including a bracket, the bracket being generally in the shape of a triangular plate, with mounting holes provided at each of the three corners of the bracket, into which a first bushing or a second bushing is installed. The bracket also has multiple assembly holes, with a gap between adjacent assembly holes. The two sides of the bracket are designated as a first side and a second side. An elastic gasket is installed on the second side of the bracket, and the second side of the bracket is connected to the compressor. An elastic gasket is provided between the second side of the bracket and the compressor.
[0008] Compared with the prior art, the advantages of this application are as follows: First, this application adopts a triangular plate-shaped bracket with mounting holes at the three corners. Combined with the first bushing or the second assembly, it forms a stable support. The structure is simple and has few parts, which is beneficial for achieving lightweight and compact layout. Second, the bracket and the compressor are connected by elastic gaskets, forming a flexible side-mounted installation. This occupies less space and can absorb compressor vibration without adding additional damping components, reducing the excitation force transmitted to the vehicle body.
[0009] In some embodiments of this application, the bracket is further provided with three assembly holes, which are arranged in a triangle and located close to the three mounting holes. These assembly holes are stepped holes. The triangular arrangement of the assembly holes preserves the overall triangular rigidity of the bracket while allowing for countersunk bolts through the stepped holes, reducing exposed bolts and further compressing the installation space.
[0010] In some embodiments of this application, the second side of the bracket has an inwardly concave curved surface at its center, and the elastic gasket is fitted onto the curved surface. The structural design of the bracket allows it to fit well against one side of the compressor, increasing the effective contact area and improving load distribution and vibration damping uniformity during side-mounted installation.
[0011] In some embodiments of this application, the surface of the elastic gasket is provided with several protruding ridges. The ridges are locally raised and can be compressed during assembly to generate additional elastic deformation, thereby enhancing the tightness of the fit between the gasket and the compressor housing and reducing the risk of fretting wear.
[0012] In some embodiments of this application, the second side of the bracket is provided with multiple reinforcing ribs, which connect to the outer periphery of the mounting hole. The reinforcing ribs directly surround the mounting hole, rigidly connecting the bolt preload path with the bracket body, improving the periphery strength of the hole, and preventing cracking of the hole edge when subjected to lateral load.
[0013] In some embodiments of this application, a first bushing is installed in one of the three mounting holes, and a second bushing is installed in the other two mounting holes. This mixed installation of two types of bushings on the same bracket allows for differentiated stiffness / damping to be provided according to different positional requirements, enabling three-dimensional vibration isolation tuning.
[0014] In some embodiments of this application, the first bushing includes a first inner core, a first outer shell, and a first rubber component. The first rubber component includes multiple support strips that connect the first outer shell and the first inner core. The multiple support strips are arranged in a cross-shaped structure. The cross-shaped support strips provide stiffness in all four radial quadrants simultaneously, maximizing strength while ensuring NHV (Noise, Vibration, and Voltage).
[0015] In some embodiments of this application, the second bushing includes a second inner core, a second outer shell, and a second rubber component. Both ends of the second inner core extend beyond the rubber component, and are respectively connected to a first limiting plate and a second limiting plate. The limiting plates are arranged on both axial sides, directly constraining the extreme displacement of the rubber component and greatly improving the durability of the part.
[0016] In some embodiments of this application, the second inner core and the second outer shell are coaxially arranged, and the second rubber component connects the second outer shell and the second inner core. The side of the second outer shell near the first limiting plate is folded outward and the surface is provided with the second rubber component. There is a gap between the second rubber component located on the end face of the second outer shell and the first limiting plate. The gap provides a certain distance of free travel. During assembly, the rubber is first compressed to fill the gap before contacting the limiting plate, which ensures initial flexibility and avoids overpressure failure, thereby improving durability margin.
[0017] In some embodiments of this application, a buffer pad is provided on the side of the second limiting plate near the second outer shell, and there is a distance between the buffer pad and the second outer shell. The buffer pad only contacts the end face of the outer shell during extreme displacement, forming a secondary buffer to absorb sudden impacts, reduce direct impact noise, and extend the bushing life.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0027] Compressor bracket assembly, as in embodiment one Figures 1-2 As shown: The bracket 1 is a triangular plate-shaped structure with mounting holes at each of its three corners. A first bushing 3 or a second bushing 4 is installed in each mounting hole to form a stable support. The structure is simple, with few parts, which is beneficial for lightweight design and compact size. The bracket 1 also has multiple assembly holes 5, with a gap between adjacent holes 5. The two sides of the bracket 1 are designated as the first side and the second side. An elastic gasket 8 is installed on the second side of the bracket 1, which connects to the compressor. An elastic gasket 8 is placed between the second side of the bracket 1 and the compressor. The bracket 1 and the compressor are connected via the elastic gasket 8, forming a flexible side-mounted installation. This design occupies less space and can absorb compressor vibration without adding additional damping components, reducing the excitation force transmitted to the vehicle body.
[0028] Example 2, as Figures 1-5 As shown, the bracket 1 is also provided with three assembly holes 5, which are distributed in a triangle and are respectively located close to the three mounting holes. The assembly holes 5 are stepped holes. The assembly holes 5 are arranged in a triangular structure to maintain the overall triangular rigidity of the bracket 1, and the stepped holes allow the bolts to be countersunk, reducing exposure and further compressing the installation space.
[0029] The second side of the bracket 1 has an inwardly concave curved surface in the middle, and the elastic gasket 8 is fitted onto the curved surface. The structural design of the bracket 1 allows it to fit well against one side of the compressor, increasing the effective contact area and improving load distribution and vibration damping uniformity during side-mounted installation.
[0030] The elastic gasket has several protruding ridges 11 on its surface. The ridges 11 are locally raised and can be compressed during assembly to generate additional elastic deformation, thereby enhancing the tightness of the fit between the gasket and the compressor housing and reducing the risk of fretting wear.
[0031] The second side of the bracket 1 is provided with multiple reinforcing ribs 12, which are connected to the outer periphery of the mounting hole 5. The reinforcing ribs 12 directly surround the mounting hole 5, rigidly connecting the bolt preload path with the main body of the bracket 1, improving the periphery strength of the hole and preventing cracking of the hole edge when subjected to side hanging force.
[0032] The first bushing 3 is installed in one of the three mounting holes, and the second bushing 4 is installed in the other two mounting holes. The two types of bushings can be mixed and matched on the same bracket 1, which can provide differentiated stiffness / damping according to different position requirements and achieve three-dimensional vibration isolation tuning.
[0033] The first bushing 3 includes a first inner core 13, a first outer shell 14, and a first rubber component 15. The first rubber component 15 includes multiple support strips 16, which connect the first outer shell 14 and the first inner core 13. The multiple support strips 16 are arranged in a cross-shaped structure. The cross-shaped support strips 16 provide stiffness in all four radial quadrants simultaneously, maximizing strength while ensuring NHV (Noise, Vibration, and Temperature).
[0034] The second bushing 4 includes a second inner core 17, a second outer shell 18, and a second rubber component 19. Both ends of the second inner core 17 extend outside the rubber component, and both ends of the second inner core 17 are respectively connected to a first limiting plate 20 and a second limiting plate 21. The limiting plates are provided on both axial sides with the first limiting plate 20 and the second limiting plate 21, which directly constrain the extreme displacement of the rubber and greatly improve the durability of the parts.
[0035] The second inner core 17 is coaxially arranged with the second outer shell 18. The second rubber component 19 connects the second outer shell 18 and the second inner core 17. The side of the second outer shell 18 closest to the first limiting plate 20 is folded outward and the surface is provided with the second rubber component 19. There is a gap between the second rubber component 19 located on the end face of the second outer shell 18 and the first limiting plate 20. The gap provides a certain distance of free travel. During assembly, the rubber is first compressed to fill the gap before contacting the limiting plate, which ensures initial flexibility and avoids overpressure failure, thereby improving durability margin.
[0036] A buffer pad 22 is provided on the side of the second limiting plate 21 near the second outer shell 18, and there is a distance between the buffer pad 22 and the second outer shell 18. The buffer pad 22 only contacts the end face of the outer shell during extreme displacement, forming a secondary buffer, absorbing sudden impact, reducing direct impact noise, and extending the bushing life.
[0037] The rest of the contents of Example 2 are the same as those of Example 1.
[0038] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
