Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically a plastic mounting bracket for an automotive air conditioning compressor and its processing equipment. Background Technology

[0002] The automotive air conditioning compressor is the core operating component of the entire vehicle's air conditioning system. The periodic vibrations it generates during operation are transmitted to the vehicle's frame through the mounting structure and ultimately into the passenger compartment, directly affecting the vehicle's NVH (noise, vibration, and harshness) performance. The compressor mounting system not only supports and fixes the compressor, but more importantly, it must effectively isolate vibration energy and suppress structural sound transmission, thereby reducing cabin noise and improving ride comfort.

[0003] Currently, traditional automotive air conditioning compressor mounts mostly use a structure of metal materials (such as cast iron or aluminum alloy) combined with a single-stage rubber vibration damping bushing. This type of design has several obvious drawbacks: First, the metal mount itself is relatively heavy, which is not conducive to achieving the goal of vehicle lightweighting; second, the single-stage vibration isolation structure has limited ability to attenuate the wide-frequency vibration energy of the compressor, especially under idling or high-speed conditions, the vibration can easily be transmitted to the crossbeam and body through the mounting point, causing resonance and abnormal noise in the cabin; in addition, metal materials are prone to corrosion in high temperature and high humidity environments, affecting their service life, while rubber bushings will age and harden over time, leading to a gradual decline in vibration isolation performance. In terms of manufacturing process, in order to facilitate compressor installation, existing mounts usually require welding installation nuts at specific positions. The commonly used method is to select a bolt that matches the nut, pass it through the through hole on the mount base and screw it into the nut, use the bolt to tighten it to make the nut fit against the mount, and then weld it in place. Although this method can achieve accurate positioning of the nut, after welding, each bolt must be unscrewed, which is cumbersome and time-consuming, seriously restricting the production cycle and processing efficiency. Utility Model Content

[0004] This utility model provides a plastic mount for an automotive air conditioning compressor and its processing equipment, which can solve the problems of heavy metal mounts, insufficient vibration isolation performance, and cumbersome nut welding and positioning process and low processing efficiency in the existing technology.

A first negative pressure member is installed at the bottom end of the first positioning member. A second positioning member is provided above the processing table, passing through a fourth through hole and extending into the welding nut. A second negative pressure member is installed at the end of the second positioning member. A pressurizing mechanism is installed between the first and second positioning members. The pressurizing mechanism is used to control the expansion of the first and second positioning members, thereby causing them to press against the inner ring of the welding nut. An air extraction assembly connected to the first and second negative pressure members is installed on the processing table.

[0009] As a further embodiment of this utility model: the first positioning component and the second positioning component have the same structure, and the first positioning component includes a positioning tube, a limiting ring, a limiting disc, an inflation tube, and an annular airbag. The inflation tube is coaxially connected to the positioning tube. The limiting disc is connected to the end of the positioning tube. The limiting disc is fitted onto the inflation tube near the positioning tube. The limiting disc, the inflation tube, and the limiting ring are all located inside the welded nut. The annular airbag is fitted onto the outside of the inflation tube between the limiting disc and the limiting ring. The annular airbag is connected to the inflation tube.

[0010] As a further embodiment of this utility model: the pressurizing mechanism includes an inflation ring, a pressurizing pump, a pressurizing pipe, a first exhaust valve, a first hose, and a second hose.

[0015] The beneficial effects of this utility model are: 1. In this utility model, the first suspension bracket is made of plastic, which effectively reduces weight compared to metal brackets, achieving lightweight design. Furthermore, the plastic bracket requires almost no consideration of corrosion resistance, reducing corrosion-related costs. By setting an inclined section with a first suspension vibration isolation pad and a main body with a second suspension vibration isolation pad, combined with the second suspension bracket, a two-stage vibration isolation system is formed, effectively attenuating the multi-directional vibration transmitted by the compressor and significantly improving NVH performance. Its structural design is reasonable; the symmetrical arrangement of the inclined section enhances stability, and the horizontal connection ensures overall rigidity. The vibration isolation pad is press-fitted into the second through hole and connected by locking bolts, ensuring reliable fastening and providing excellent vibration isolation. Simultaneously, the innovative design of pre-welding nuts to the second suspension bracket completely avoids the cumbersome operation of temporarily using positioning bolts in traditional processes, greatly simplifying the compressor assembly process and significantly improving production efficiency and assembly consistency.

[0016] 2. In this utility model, the first and second positioning components are precisely inserted into the welding nut, and the expansion of the first and second positioning components is controlled by the pressure boosting mechanism to make them tightly press against the inner wall of the welding nut, greatly increasing the friction between them and the welding nut. On this basis, the first and second negative pressure components simultaneously apply axial tension, which can firmly pull the welding nut tight and fit it against the U-shaped part and the mounting part of the second suspension bracket, completely eliminating the assembly gap, ensuring the accuracy of the welding position and the reliability of the connection, and effectively improving the welding quality. After welding, the pressure is quickly released to restore the first and second positioning components to their original state, and the welded second suspension bracket can be directly removed, realizing quick installation and removal. This completely eliminates the screw-in and screw-out process required for traditional bolt positioning, significantly improving production efficiency, reducing labor intensity, and ensuring product consistency.

Detailed Implementation

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1-5As shown, this utility model is a plastic suspension for an automotive air conditioning compressor, including a first suspension bracket 100 made of plastic. In this embodiment, the first suspension bracket 100 is specifically made of PA6-GF50 material. The first suspension bracket 100 includes an inclined portion 102 with a first through hole 101, a main body portion 104 with a second through hole 103, and a horizontal portion 105. The inclined portion 102 is symmetrically arranged at both ends of the main body portion 104. The first through hole 101 vertically penetrates the inclined portion 102, and a first suspension vibration damping pad 200 is press-fitted into the first through hole 101. The horizontal portion 105 is connected to... Between two symmetrical inclined portions 102, a second through hole 103 is provided at the four corners of the main body portion 104, and a second suspension vibration isolation pad 300 is press-fitted into the second through hole 103. A second suspension bracket 400 for mounting the compressor is symmetrically provided above the main body portion 104. In this embodiment, the second suspension bracket 400 is made of sheet metal. A locking bolt 301 connected to the second suspension bracket 400 is passed through the second suspension vibration isolation pad 300. A welding nut 302 is welded on the second suspension bracket 400 to provide a connection point for the locking bolt 301 and the compressor installation.

[0022] It should be noted that during use, the vibration generated by the compressor is first transmitted to the second suspension bracket 400 through the welding nut 302, and then the vibration energy is transmitted to the second suspension vibration isolation pad 300 pressed into the second through hole 103 through the locking bolt 301. The vibration is absorbed and attenuated by its elastic deformation, forming the first level of vibration isolation. The vibration energy after initial attenuation is transmitted to the main body 104 of the first suspension bracket 100. The vibration is transmitted to the inclined parts 102 symmetrically distributed at both ends through the main body 104, and finally introduced into the first suspension vibration isolation pad 200 in the first through hole 101. The remaining low-frequency vibration is isolated and dissipated by its elastic deformation, completing the second level of vibration isolation. Only the small residual vibration after being fully attenuated by the two-stage vibration isolation system is transmitted to the vehicle body mounting point through the first suspension vibration isolation pad 200, thereby significantly blocking the transmission path of vibration to the cabin and comprehensively improving the NVH performance of the vehicle.

[0023] like Figure 1 and Figures 3-4As shown, the first suspension vibration isolation pad 200 and the second suspension vibration isolation pad 300 have the same structure. The first suspension vibration isolation pad 200 includes an inner core 201, a main spring rubber 202 and an outer ring 203 connected sequentially from the inside to the outside. The inner core 201, the main spring rubber 202 and the outer ring 203 are vulcanized together by a rubber injection vulcanization process. The main spring rubber 202 includes an outer ring portion 2021, an inner ring portion 2022, a connecting portion 2023 and anti-collision blocks 2024. The outer ring portion 2021 and the inner connecting portion 2023 are connected by the connecting portion 2023. Multiple anti-collision blocks 2024 are distributed circumferentially along both ends of the outer ring portion 2021. The inner core 201 is located inside the inner ring portion 2022 and the outer ring 203 is located outside the outer ring portion 2021. The two ends of the outer ring 203 are in contact with the anti-collision blocks 2024 distributed vertically.

[0024] It should be noted that in this embodiment, the first suspension vibration isolation pad 200 is inclined, so that the main spring rubber 202 of the first suspension vibration isolation pad 200 is inclined at an angle. This allows for a lower radial stiffness while increasing the axial stiffness, thus enabling it to support the weight of the compressor. When vibration is transmitted to the second suspension vibration isolation pad 300 through the locking bolt 301, it first acts on the inner core 201. The inner core 201 radially transmits the force to the inner annular portion 2022 of the main spring rubber 202 that is tightly connected to it. The vibration energy is transmitted through the connecting portion 2023 between the outer annular portion 2021 and the inner annular portion 2022. The vibrations are transmitted between parts 2022. The connecting part 2023 effectively absorbs and attenuates most of the high-frequency vibrations through its elastic shear deformation. The outer ring part 2021 transmits the pre-filtered vibrations to the outer ring 203, and finally to the mounting base. The circumferentially distributed anti-collision blocks 2024 can play a role in axial limiting, which can ensure the good fatigue durability of the first suspension vibration isolation pad 200 and the second suspension vibration isolation pad 300. At the same time, by limiting the movement of the first suspension vibration isolation pad 200 and the second suspension vibration isolation pad 300, the movement of the entire compressor module is limited, preventing interference with other module components.

[0025] like Figure 1 and Figure 5 As shown, the second suspension bracket 400 includes a U-shaped portion 401, a mounting portion 402, a third through hole 403, and a fourth through hole 404. The two mounting portions 402 are connected to the opposite sides of the U-shaped portion 401 near the end, and the mounting portions 402 extend upward. The third through hole 403 is symmetrically disposed through the corner of the U-shaped portion 401, and the fourth through hole 404 is disposed through the mounting portion 402. Both the fourth through hole 404 and the third through hole 403 are coaxially disposed with the welding nut 302.

[0026] It should be noted that the U-shaped part 401 is connected and fixed to the first suspension bracket 100 below through the third through hole 403 by the locking bolt 301, forming the main load-bearing structure; the two upwardly extending mounting parts 402 provide mounting points for the compressor through the fourth through hole 404 on them; the coaxial arrangement of the welding nut 302 with the third through hole 403 and the fourth through hole 404 ensures that the locking bolt 301 can pass through vertically and apply a uniform preload, thereby reliably connecting the compressor, the second suspension bracket 400 and the first suspension bracket 100 into a whole.

[0027] like Figures 6-11 This utility model embodiment provides a processing device for a plastic suspension mount of an automotive air conditioning compressor, including a processing table 700 supporting a second suspension bracket 400. A first positioning member 500 is provided through the processing table 700, passing through a third through hole 403 and extending into a welding nut 302. A first negative pressure member 600 is installed at the bottom end of the first positioning member 500. A second positioning member 1000 is provided above the processing table 700, passing through a fourth through hole 404 and extending into the welding nut 302. A second negative pressure member 1100 is installed at the end of the second positioning member 1000. A pressurizing mechanism 900 is installed between the first positioning member 500 and the second positioning member 1000. The pressurizing mechanism 900 is used to control the expansion of the first positioning member 500 and the second positioning member 1000, thereby pressing them against the inner ring of the welding nut 302. An air extraction assembly connected to the first negative pressure member 600 and the second negative pressure member 1100 is installed on the processing table 700.

[0028] It should be noted that during use, the second suspension bracket 400 to be welded is placed on the processing table 700, so that the first positioning member 500 passes through the third through hole 403 to position the second suspension bracket 400. Then, the second positioning member 1000 is controlled to translate so that it passes through the fourth through hole 404 and extends into the welding nut 302. The pressurization mechanism 900 is then activated to fill the first positioning member 500 and the second positioning member 1000 with high-pressure gas, causing them to expand radially and tightly press against the inner ring of the welding nut 302. Then, the extraction is started. The air assembly applies a downward pulling force to the first positioning component 500 through the first negative pressure component 600, and a lateral pulling force to the second positioning component 1000 through the second negative pressure component 1100. At this time, the welding nut 302 is firmly pressed onto the corresponding surfaces of the U-shaped part 401 and the mounting part 402 of the second suspension bracket 400, eliminating all assembly gaps. After welding is completed, the pressurization mechanism 900 releases pressure to restore the positioning component to its original state, and the air extraction assembly releases its adsorption, allowing the weldment to be removed. The entire process achieves fast, accurate, and automated welding positioning.

[0029] like Figure 6 and Figure 9As shown, the first positioning component 500 and the second positioning component 1000 have the same structure. The first positioning component 500 includes a positioning tube 501, a limiting ring 502, a limiting disc 503, an inflation tube 504, and an annular airbag 505. The inflation tube 504 is coaxially connected to the positioning tube 501. The limiting disc 503 is connected to the end of the positioning tube 501 and is fitted onto the inflation tube 504 near the positioning tube 501. The limiting disc 503, the inflation tube 504, and the limiting ring 502 are all located inside the welding nut 302. The annular airbag 505 is fitted onto the outside of the inflation tube 504 between the limiting disc 503 and the limiting ring 502, and the annular airbag 505 is connected to the inflation tube 504.

[0030] It should be noted that in this embodiment, the annular airbag 505 is made of high-temperature resistant silicone. When the positioning tube 501 carrying the inflation tube 504 is inserted into the welding nut 302, the limiting plate 503 and the limiting ring 502 together limit the axial position of the annular airbag 505 inside the nut. The pressurizing mechanism 900 injects high-pressure gas into the annular airbag 505 through the inflation tube 504, causing it to expand radially and press tightly against the inner wall of the welding nut 302. The huge friction force generated is used to achieve precise positioning and rigid fixation. After welding is completed, the pressurizing mechanism 900 depressurizes, the gas in the annular airbag 505 is discharged and returns to its original state, the friction force disappears, and the positioning tube 501 together with the inflation tube 504 can be smoothly pulled out from the welding nut 302 to prepare for the next welding operation.

[0031] like Figure 6 , Figure 8 and Figure 10 As shown, the pressurization mechanism 900 includes an inflation ring 901, a booster pump 902, a booster pipe 903, a first exhaust valve 904, a first hose 905, and a second hose 906. The inflation ring 901 is fixedly fitted onto the edge of the processing table 700. The positioning pipe 501 of the first positioning member 500 is connected to the inflation ring 901 through the first hose 905. The positioning pipe 501 of the second positioning member 1000 is connected to the inflation ring 901 through the second hose 906. The booster pump 902 is installed on the top of the processing table 700, and the air outlet of the booster pump 902 is connected to the inflation ring 901 through the booster pipe 903. The exhaust valve is installed on the inflation ring 901.

[0032] It should be noted that when the booster pump 902 is started, the high-pressure gas generated is delivered to the inflation ring 901 through the booster pipe 903. The high-pressure gas then enters the inflation pipes 504 of the first positioning member 500 and the second positioning member 1000 through the first hose 905 and the second hose 906 respectively, and finally inflates the annular airbag 505 to press against the inner wall of the welding nut 302. After the welding is completed, the first exhaust valve 904 is opened to discharge the gas in the inflation ring 901 and the connected pipes. The pressure in the annular airbag 505 is released and returns to its original state, thereby releasing the lock on the welding nut 302.

[0033] like Figure 6 and Figure 9 As shown, the first negative pressure component 600 and the second negative pressure component 1100 have the same structure. The first negative pressure component 600 includes a cylinder 601, a piston 602 and a spring 603. The piston 602 is installed at the end of the positioning tube 501 away from the inflation tube 504. The piston 602 is slidably arranged along the cylinder 601. The spring 603 is installed between the piston 602 and the inner end of the cylinder 601.

[0034] It should be noted that when the vacuum assembly is started, a negative pressure is formed inside the cylinder 601. Under the action of the pressure difference, the piston 602 is pushed to slide towards the inner end of the cylinder 601 against the elastic force of the spring 603. The movement of the piston 602 generates an axial pulling force through the positioning tube 501 connected to it, thereby pulling the first positioning member 500 and the second positioning member 1000 that have been expanded and positioned, ensuring that the welding nut 302 is tightly attached to the corresponding mounting surface of the second suspension bracket 400. After the welding is completed, the vacuum assembly stops working, the pressure inside the cylinder 601 is restored, and at this time the restoring force of the spring 603 pushes the piston 602 to reset, releasing the axial pulling force and preparing for the next operation.

[0035] like Figures 6-7 and Figure 11 As shown, the air extraction assembly includes a cavity 701, an air pump 702, an air inlet valve 703, an L-shaped pipe 704, and a third flexible hose 705. The cavity 701 is disposed inside the processing table 700. The air pump 702 is installed at the bottom of the processing table 700, and the air inlet pipe of the air pump 702 is connected to the cavity 701. The cylinder 601 of the first negative pressure component 600 is connected to the cavity 701 near the bottom end through the symmetrically arranged L-shaped pipes 704. The cylinder 601 of the second negative pressure component 1100 is connected to the cavity 701 near the end end through the third flexible hose 705. The air inlet valve 703 is installed on the processing table 700.

[0036] It should be noted that the vacuum pump 702 draws air from the cavity 701 to create a negative pressure. This negative pressure is transmitted to the cylinder 601 of the first negative pressure component 600 through the symmetrically arranged L-shaped pipes 704, and simultaneously to the cylinder 601 of the second negative pressure component 1100 through the third hose 705. The negative pressure generated in each cylinder 601 drives the piston 602 inside to move and generate a pulling force. When it is necessary to release the adsorption, the vacuum pump 702 is turned off and the air inlet valve 703 is opened to allow external air to enter the cavity 701, thereby balancing the system pressure and completing one working cycle.

[0037] like Figure 6 and Figure 9 As shown, a fixing plate 1200 is installed on the top of the processing table 700, and a cylinder 1201 is installed on one side of the fixing plate 1200. The piston rod of the cylinder 1201 is connected to the end of the cylinder 601 of the second negative pressure component 1100.

[0038] It should be noted that the cylinder 1201 pushes the cylinder 601 of the second negative pressure component 1100 to move horizontally, causing the second positioning component 1000 to be vertically inserted into the fourth through hole 404 and penetrate into the welding nut 302; after the welding is completed, the cylinder 1201 drives the second negative pressure component 1100 and the second positioning component 1000 to reset, so that they are removed from the welding nut 302 and the fourth through hole 404, thereby facilitating the removal of the welded second suspension bracket 400 from the processing table 700.

[0039] like Figure 6 , Figure 9 and Figure 11 As shown, a positioning hole 706 corresponding to the third through hole 403 is provided through the processing table 700. The positioning tube 501 of the first positioning member 500 is provided through the positioning hole 706, and the diameter of the positioning hole 706 is equal to the outer diameter of the positioning tube 501.
