Abstract
Description
Technical Field
[0001] This utility model belongs to the field of engine technology, specifically a novel air conditioning compressor bracket. Background Technology
[0002] During the operation of the engine system, the air conditioning compressor, as an important collaborative accessory, directly affects the overall performance of the engine through its stable installation and efficient operation. However, different customers in the market have different requirements for the same model of air conditioning compressor in terms of displacement and status based on factors such as usage scenarios and cost budgets, resulting in diverse system configurations. The current industry-standard solution is to design and manufacture a custom air conditioning compressor bracket to meet different needs, and then disassemble and install it during use to switch the air conditioning compressor status. This approach not only significantly increases the cost investment of enterprises in R&D, production, and warehousing, but also causes great inconvenience to users and reduces usage efficiency due to the frequent disassembly and installation operations.
[0003] Meanwhile, the installation of the existing air conditioning compressor bracket requires a large number of mounting holes to be made in different parts of the engine block, which not only damages the integrity of the cylinder block structure, but also increases the processing complexity and manufacturing cost. In addition, when the engine wheel system is running, the vibration generated by various accessories, including the air conditioning compressor, will be transmitted through the bracket, causing obvious noise. More seriously, long-term vibration can easily lead to fatigue fracture of the bracket, accessory parts or fixing bolts, posing a serious safety hazard.
[0004] With the improvement of engine performance and the popularization of compact engine bay layout, the weight and size of accessories are constantly increasing, which puts forward higher requirements for air conditioning compressor brackets: they must have stronger load-bearing capacity to ensure stable support under complex working conditions; and they must achieve lightweight and miniaturized design to accurately avoid the air conditioning compressor and other components and avoid spatial interference. Summary of the Invention
[0005] To address the problems existing in the background technology, this utility model provides a novel air conditioner compressor bracket.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel air conditioner compressor bracket, comprising a bracket body, mounting hole one, mounting hole two, mounting hole three, mounting hole four, mounting hole five, mounting hole six, mounting hole seven, mounting hole eight, mounting hole nine, mounting hole ten, mounting hole eleven, mounting hole twelve, three weight-reducing structures, and multiple reinforcing ribs;
[0007] The bracket body has a C-shaped structure with a concave inner wall to avoid the air conditioning compressor. The bracket body has a mounting hole 1 that mates with the synchronous chain cover, mounting holes 2 and 3 that mate with the oil pan, mounting holes 4 and 5 that mate with the cylinder block, mounting holes 6, 7, 8 and 9 that mate with compressor 1, and mounting holes 10, 11 and 12 that mate with compressor 2. The bracket body has three weight-reducing structures and multiple reinforcing ribs.
[0008] Each of the reinforcing ribs is distributed around the edge of the support body and the compressor mounting hole to enhance the rigidity of the support and suppress deformation caused by operating vibration.
[0009] Each of the aforementioned weight-reduction structures is a hollow groove or through-hole structure located in a non-critical stress-bearing part of the support body, thereby minimizing the weight of the support while ensuring structural strength.
[0010] The bracket body is made of cast aluminum and has a wall thickness of 8mm to improve the strength of the installation area.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. Stable support and load distribution: The bracket body is fixed to the synchronous chain cover, oil pan and engine block through mounting holes one, two, three, four and five, forming a three-point joint support structure of "cylinder block-oil pan-synchronous chain cover", which effectively distributes the load generated during operation, greatly improves the overall stability, reduces the risk of bracket damage caused by uneven stress, and ensures the long-term stable operation of the air conditioning compressor.
[0013] 2. Space optimization and structural avoidance: The bracket body adopts a C-shaped structure and an inner wall concave design, which provides ample installation space for the air conditioning compressor, precisely avoids compressor components, avoids interference during assembly and operation, ensures the installation compatibility and smooth operation of the compressor and bracket, and improves overall assembly efficiency and equipment reliability.
[0014] 3. Versatility and strong compatibility: The bracket body is equipped with two sets of compressor mounting holes, which can be adapted to compressor one with four mounting points and compressor two with three mounting points through different combinations of hole positions, realizing the "one bracket for multiple purposes" function. This design effectively reduces the need for replacement of special parts, reduces production costs and inventory management pressure, improves product versatility and market adaptability, and brings significant economic benefits to enterprises.
[0015] 4. Vibration suppression and reliability improvement: Multiple reinforcing ribs are reasonably distributed around the edge of the support body and the compressor mounting hole. By increasing local rigidity, the support deformation caused by compressor operation vibration is effectively suppressed, preventing failures such as bolt breakage caused by vibration, extending the service life of the support and related components, improving the reliability and safety of the entire system, and reducing equipment maintenance costs and downtime.
[0016] 5. Lightweight and Layout Adaptation: The three weight-reducing structures adopt a hollowed-out groove or through-hole design and are located in non-critical load-bearing parts of the bracket body. While ensuring structural strength, the weight of the bracket is reduced to the minimum, meeting the strict requirements of lightweighting for compact engine compartment layout. At the same time, the selection of cast aluminum material has both high strength and lightweight characteristics, further reducing the overall weight of the engine and optimizing vehicle power performance and fuel economy.
[0017] 6. Strength Guarantee and Load-Bearing Optimization: The bracket body is made of cast aluminum material with a wall thickness of 8mm. Through local reinforcement design, the strength of the installation part is significantly improved, which can effectively withstand the dynamic load generated by the compressor during operation. This ensures that the bracket maintains good structural performance under complex working conditions, providing a solid and reliable support foundation for the stable operation of the air conditioning compressor.
[0018] In summary, this utility model achieves breakthroughs in stability, compatibility, lightweighting, and strength through innovative structural design, reasonable material application, and ingenious functional layout, effectively improving product performance and corporate competitiveness, and possessing outstanding practical value and market promotion potential.

[0019] Figure 1 This is a schematic diagram of the overall structure of this utility model;
[0020] Figure 2 This is the front view of this utility model. Detailed Implementation
[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0022] This embodiment describes a novel air conditioner compressor bracket, including a bracket body 1, mounting hole one 2, mounting hole two 3, mounting hole three 4, mounting hole four 5, mounting hole five 6, mounting hole six 7, mounting hole seven 8, mounting hole eight 9, mounting hole nine 10, mounting hole ten 11, mounting hole eleven 12, mounting hole twelve 13, three weight-reducing structures 15, and multiple reinforcing ribs 14.
[0023] The bracket body 1 has a C-shaped structure with a concave inner wall to avoid the air conditioning compressor. The bracket body 1 has mounting holes 1-2 that mate with the synchronous chain cover, mounting holes 2-3 and 3-4 that mate with the oil pan, mounting holes 4-5 and 5-6 that mate with the cylinder block, mounting holes 6-7, 7-8, 8-9 and 9-10 that mate with compressor 1, mounting holes 11-11, 11-12 and 12-13 that mate with compressor 2, and three weight-reducing structures 15 and multiple reinforcing ribs 14.
[0024] Each of the reinforcing ribs 14 is distributed around the edge of the support body 1 and the compressor mounting hole to enhance the rigidity of the support and suppress deformation caused by operating vibration.
[0025] Each of the weight-reducing structures 15 is a hollow groove or through hole structure, located in a non-critical stress part of the support body 1, so as to reduce the weight of the support to the maximum extent while ensuring structural strength.
[0026] The bracket body 1 is made of cast aluminum and has a wall thickness of 8mm to improve the strength of the installation area.
[0027] When using this utility model, the bracket body 1 is fixed to the synchronous chain cover through mounting hole 1 2 (preferably by bolt connection), fixed to the oil pan through mounting hole 2 3 and mounting hole 3 4, and fixed to the engine block through mounting hole 4 5 and mounting hole 5 6, forming a three-point joint support structure of "cylinder block-oil pan-synchronous chain cover", which distributes the load and improves the overall stability. The concave design of the C-shaped structure reserves space for the air conditioning compressor to avoid interference.
[0028] The bracket body 1 is provided with two sets of compressor mounting holes:
[0029] The compressor is a compressor with four mounting points, which is fixed by mounting holes 6.7, 7.8, 8.9, and 9.10 (preferably by bolt connection).
[0030] Compressor 2 is a compressor with three mounting points, which is fixed by mounting hole 11, mounting hole 12, and mounting hole 13;
[0031] By selecting different combinations of holes, the same bracket can be compatible with air conditioning compressors of two different displacements and states, achieving "one bracket for multiple purposes" and reducing the need for replacement of special parts.
[0032] Multiple reinforcing ribs 14 are distributed on the front edge of the bracket and key connection parts such as around the compressor mounting hole. By increasing local stiffness, vibration is suppressed, and bracket deformation or bolt breakage caused by compressor operation vibration is avoided. Three weight-reducing structures 15 are hollow grooves or through holes, which are set in non-stressed areas of the bracket (such as non-load-bearing parts on the edge of the bracket body). They reduce weight without affecting strength and are suitable for compact cabin layout.
[0033] The bracket is made of cast aluminum material (preferably aluminum alloy ZL101A, etc.), which has both high strength and lightweight characteristics, reducing the overall weight of the engine. The bracket body has a wall thickness of 8mm, and the load-bearing capacity of this area is improved through local reinforcement to adapt to the dynamic load during compressor operation.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
