Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, specifically to compressors and new energy vehicles. Background Technology

[0002] During compressor assembly, the intake and exhaust port pressure plates, as key airtight sealing and structural fixing components, are typically rigidly connected to the compressor housing via double-ended studs. The reliability of this connection point directly determines whether the compressor can operate stably for a long period.

[0003] However, during operation, the compressor experiences multiple complex and alternating operating conditions:

[0004] First, the mechanical vibrations generated by the motor and moving parts (such as pistons or scroll plates) are continuous. These high-frequency, low-amplitude or low-frequency, high-amplitude vibrations are transmitted to the connecting studs, generating periodic alternating stresses on them. This can easily lead to small relative slippage between the threaded pairs, i.e., "creep," which causes the preload to gradually decrease.

[0005] Secondly, during the intake and exhaust processes, the internal gas pressure of the compressor is not constant but fluctuates dramatically over time. This pressure fluctuation, acting on the pressure plate, translates into pulsating tensile loads on the studs, further exacerbating fatigue damage to the threaded connections. An even more severe challenge arises from temperature variations—during startup, operation, and shutdown, the compressor casing and internal components experience significant temperature changes, leading to differences in the thermal expansion coefficients of different materials (such as studs, pressure plates, and the casing), thus inducing uneven thermal stress. This thermal stress, combined with mechanical stress, can cause the studs to gradually loosen through repeated cycles of thermal expansion and contraction.

[0006] The combined effects of vibration, pressure fluctuations, and temperature changes create a typical dynamic load environment, which can easily lead to a decrease in the preload of the studs, i.e., loosening. Once the studs loosen, a series of chain failure reactions will be triggered: the most direct manifestation is the destruction of the seal at the suction and discharge ports, leading to leakage of high-pressure refrigerant or air, causing a sharp drop in compressor efficiency and an increase in energy consumption; if the loosening progresses further, it may cause displacement or deflection of the pressure plate, disrupting its parallel compression with the housing, not only exacerbating leakage but also potentially causing severe wear or even jamming due to interference with moving parts, ultimately resulting in the functional failure of the entire compressor.

[0007] This problem is particularly prominent and severe in the field of new energy vehicles. Compared with traditional vehicles, new energy vehicles (especially pure electric vehicles) often have faster acceleration and higher speeds, which means that the vehicles themselves are subjected to more frequent and severe road impacts and body vibrations. As part of the vehicle system, the vibration load on the air conditioning compressor or air suspension compressor is thus amplified. Under these harsh conditions, the risk of loosening at the intake and exhaust port connection points increases significantly. Once the studs become loose or the pressure plate shifts during high-speed driving, it will not only cause an immediate loss of the system's cooling or air supply function, affecting driving comfort and battery thermal management efficiency, but more dangerously, the loosened parts may become potential flying objects in the cabin, or in extreme cases, cause serious safety accidents such as instantaneous refrigerant leakage and pipe rupture, posing a direct threat to vehicle driving safety. Therefore, for the compressors of new energy vehicles, the anti-loosening design, process control, and reliability verification of the intake and exhaust port stud connections have become one of the key technical links concerning the safety and performance of the entire vehicle, and must be given extremely high attention.

[0008] In existing technologies, common techniques for preventing studs from loosening include:

[0009] Anti-loosening washers, such as spring washers and toothed washers, are used to prevent nuts from loosening through elastic deformation or mechanical engagement. However, this method requires additional parts, increasing assembly complexity and cost.

[0010] Pre-applied threadlocker: An adhesive such as anaerobic adhesive is applied to the threaded area, which forms a mechanical lock after curing. However, this method has problems such as complex process, adhesive layer aging, and difficulty in disassembly.

[0011] Using anti-loosening nuts: For example, by setting a high-precision flat surface on the end face of the nut, and cooperating with the upper and lower workpieces to achieve anti-loosening. However, this solution can only prevent the nut from loosening, but cannot prevent the stud itself from loosening from the mounting base under vibration.

[0012] However, the existing technology still lacks a stud structure that is simple in structure, requires no additional parts, and can prevent both the stud itself and the nut from loosening.

[0013] In view of this, the present invention provides a compressor and a new energy vehicle. Utility Model Content

Figure 6 This is a partially enlarged view of the anti-slip double-ended stud of the compressor of this utility model. Figures 1 to 6As shown, the compressor of this utility model includes: a housing 1, two anti-slip double-ended studs 5, an exhaust seat 3, and an intake seat 8. The housing 1 includes an exhaust port 2 and an intake port 7, with a threaded hole 10 having an annular anti-slip shoulder 11 on the periphery of each of the exhaust port 2 and intake port 7. Each anti-slip double-ended stud 5 includes a first stud 51, an annular anti-slip flange 53, and a second stud 52 arranged sequentially along the axial direction. The first stud 51 is screwed into the threaded hole 10, and the annular anti-slip flange 53 engages with the annular anti-slip shoulder 11 to prevent rotation. The exhaust seat 3 has an exhaust pipe 6 that connects to the exhaust port 2. A corresponding second stud 52 is sleeved in the through hole 31 of the exhaust seat 3 and tightened by a nut 4. The intake seat 8 has an intake pipe 9 that connects to the intake port 7. A corresponding second stud 52 is sleeved in the through hole 31 of the intake seat 8 and pressed by a nut 4 (in this utility model, the screw hole structure of the exhaust port 2 and the intake port 7 are the same, so they are both referred to as screw hole 10; the two anti-slip double-ended studs connecting the exhaust port 2 and the intake port 7 have the same structure, so they are both referred to as two anti-slip double-ended studs 5; the nut structure that presses the exhaust seat 3 and the intake seat 8 is the same, so they are both referred to as nut 4). The compressor of this utility model includes a compressor suction and exhaust port pressure plate fixing stud with an anti-loosening structure. By adding an anti-loosening flange plane and a plane wedge structure to the stud itself, it is ensured that the stud itself will not loosen without adding parts or thread sealant. Since the stud body structure in this utility model can achieve the anti-loosening function, no additional parts or thread sealant are required, simplifying the assembly process and improving reliability.

[0068] In a preferred embodiment, the annular anti-slip flange 53 has a first surface opposite to the second stud 52 with a continuous annular structure or a plurality of first wedge blocks 54 distributed intermittently.

[0069] In a preferred embodiment, the distance H between the intersection of the outer surfaces of the edges of the wedge structure of the first wedge block 54 and / or the second wedge block 12 and the first surface of the annular anti-slip flange 53 is 0.1 to 0.2 times the thickness T of the annular anti-slip flange 53, but is not limited thereto.

[0071] In a preferred embodiment, the annular anti-slip flange 53 has a first anti-loosening wedge thread on its first surface away from the second stud 52, and the annular anti-slip shoulder 11 has a second anti-loosening wedge thread. The first anti-loosening wedge thread and the second anti-loosening wedge thread engage in one direction, but this is not a limitation.

[0072] In a preferred embodiment, the bottom surface of the air intake seat 8 presses against the upper surface of the air intake 7 and the second surface of the corresponding annular anti-slip shoulder 11. The second surface is opposite to the first surface, but this is not a limitation.

[0073] In a preferred embodiment, the bottom surface of the exhaust seat 3 presses against the upper surface of the exhaust port 2 and the second surface of the corresponding annular anti-slip shoulder 11. The second surface is opposite to the first surface, but this is not a limitation.

[0078] In a preferred embodiment, nut 4 is a non-slip nut, but is not limited thereto.

[0079] The specific embodiments of this utility model include:

[0080] like Figures 1 to 6As shown, this utility model provides a split-type swing sleeve structure for a scroll compressor, mainly comprising: a housing 1, two anti-slip double-ended studs 5, an exhaust seat 3, and an intake seat 8. The housing 1 includes an exhaust port 2 and an intake port 7, with a screw hole 10 having a concave annular anti-slip shoulder 11 on the periphery of both the exhaust port 2 and the intake port 7. Each anti-slip double-ended stud 5 includes a first stud 51, an annular anti-slip flange 53, and a second stud 52 arranged sequentially along the axial direction. The first stud 51 is screwed into the screw hole 10, and the annular anti-slip flange 53 engages with the annular anti-slip shoulder 11 to prevent rotation. The exhaust seat 3 has an exhaust pipe 6 that connects to the exhaust port 2. A corresponding second stud 52 is sleeved in the through hole 31 of the exhaust seat 3 and pressed by a nut 4. The intake seat 8 has an intake pipe 9 that connects to the intake port 7. A corresponding second stud 52 is sleeved in the through hole 31 of the intake seat 8 and pressed by a nut 4. The annular anti-slip flange 53 has a continuous annular structure or a plurality of intermittently distributed first wedge blocks 54 on its first surface opposite to the second stud 52. When the first wedge blocks 54 are tightened onto the concave annular anti-slip shoulder 11, the upper surface of the annular anti-slip shoulder 11 undergoes elastic or plastic deformation to form an engagement. Since the annular anti-slip shoulder 11 is concave, even if the annular anti-slip shoulder 11 deforms, it effectively prevents the deformation from being transmitted to the surface of the exhaust port 2. Therefore, the deformation of the annular anti-slip shoulder 11 in this invention will not affect the flatness of the surface of the exhaust port 2. The above structural combination enables the pipeline connection of the compressor of this invention to simultaneously possess the connection strength of deformation engagement and the tight mating effect brought by the smooth mounting surface. The bottom surface of the air inlet seat 8 presses against the upper surface of the air inlet 7 and the corresponding second surface of the annular anti-slip shoulder 11, the second surface being opposite to the first surface. The bottom surface of the vent seat 3 presses against the upper surface of the vent port 2 and the second surface of the corresponding annular anti-slip shoulder 11. The second surface is opposite to the first surface, so that the bottom surface of the vent seat 3 simultaneously presses against the upper surface of the vent port 2 and the second surface of the corresponding annular anti-slip shoulder 11, with the second surface opposite to the first surface. A guide post 55 is provided on the side of the second stud 52 of the anti-slip double-ended stud 5 facing away from the annular anti-slip flange 53. The distance H from the intersection point of the outer surfaces of the wedge-shaped structures of the first wedge block 54 and / or the second wedge block 12 to the first surface of the annular anti-slip flange 53 is 0.1 to 0.2 times the thickness T of the annular anti-slip flange 53. The diameter D of the annular anti-slip flange 53 is 1.2 to 2 times the thread diameter d. The thickness T of the annular anti-slip flange 53 is 0.8 to 2 times the thread pitch P. These dimensional ranges ensure the anti-loosening effect while also considering the strength and assembly feasibility of the stud.

[0081] During assembly, when the guide post 55 is used to screw the first stud 51 into the screw hole 10 next to the compressor's suction and discharge ports, the annular anti-slip flange 53 contacts the concave annular anti-slip shoulder 11 next to the suction and discharge ports. As the first stud 51 is tightened further, the inclined surface of the first wedge block 54 of the annular anti-slip flange 53 tightens, causing elastic or plastic deformation of the upper surface of the annular anti-slip shoulder 11 to form a meshing (partial engagement) to prevent the stud from rotating in the opposite direction and loosening under vibration. The bottom surface of the exhaust seat 3 presses against the upper surface of the exhaust port 2 and the corresponding second surface of the annular anti-slip shoulder 11. The second stud 52 of the anti-slip double-ended stud 5 passes through the through hole 31 of the exhaust seat 3 and protrudes. Finally, the nut 4 (anti-slip nut) is tightened along the second stud 52, pressing the upper surfaces of the exhaust seat 3 and the exhaust port 2 together. This invention utilizes the reverse resistance generated on the mounting end face by the anti-loosening wedge structure formed between the annular anti-slip flange 53 and the annular anti-slip shoulder 11 to prevent the first stud 51 from loosening itself when the nut is screwed into or out of the second stud 52. Furthermore, the second stud 52 is used to install the exhaust seat 3 (similar to a pressure plate structure) and is tightened by the nut 4. Since the first stud 51 itself has anti-loosening capabilities, it will not rotate even when the nut 4 is removed, improving maintenance convenience. Similarly, even under other forms of shaking, the first stud 51 will not rotate, ensuring the connection strength between the exhaust port and the exhaust pipe.

[0082] Compared with the prior art, the present invention has the following beneficial effects:

[0083] Integrated anti-loosening structure: By setting a mounting flange with a wedge structure on the stud body, the stud itself is anti-loosening, eliminating the need for additional anti-loosening parts;

[0084] Simplified process: Eliminates the steps of pre-applying thread-locking adhesive or installing anti-loosening washers, reducing assembly complexity;

[0085] High reliability: The wedge-shaped structure forms a mechanical engagement with the mounting surface, effectively resisting loosening caused by vibration;

[0086] High compatibility: The assembly method is the same as that of ordinary double-ended studs, without the need to change the existing assembly process;

[0087] Low cost: The structure is simple and the manufacturing process is similar to that of ordinary studs, with no additional parts cost.

[0088] This utility model also provides a new energy vehicle, including the compressor described above. Specifically, the air conditioning system in the new energy vehicle of this utility model uses the above-described compressor structure, and the relevant technical features are as described above, and will not be repeated here. Because the new energy vehicle of this utility model uses the above-described compressor, it can avoid the loosening of studs due to bumps and vibrations during vehicle operation, thus improving vehicle driving safety.

[0089] In summary, the purpose of this utility model is to provide compressors and new energy vehicles that can achieve anti-loosening function through the stud body structure design, without the need for additional parts or thread glue, simplifying the assembly process and improving reliability.

[0090] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
