[0036] Compressors, such as electric compressors, integrate electronic control components. The cover is part of the compressor and fits with the compressor housing to define a chamber for housing the electronic control components, thus protecting the electronic components. The cover has certain corrosion resistance and sealing properties. In related technologies, a sealing gasket is usually used to seal the cover and the housing. A sealing gasket is a material used to fill and seal the gap between two surfaces, preventing substances such as gases, liquids, or dust from leaking or seeping between the two surfaces.
[0037] However, with the use of the compressor, the chemicals in the salt spray environment corrode the gaskets, causing them to age and leading to a decrease in sealing performance or even failure. Since the cover typically has a short sealing distance and the gaskets rely on pre-tightening force for sealing, chemicals in the salt spray environment can penetrate into the gaps between the gasket and the substrate, causing corrosion and damage to the substrate. This is especially true as the pre-tightening force weakens, making it even harder to protect the integrity of the substrate. Chemicals in the salt spray environment can also enter the interior through tiny defects or cracks in the gaskets, leading to corrosion and damage to internal components and compromising their normal operation.
[0038] Therefore, although gaskets can prevent salt spray from entering the interior to some extent, they cannot completely solve the problem of salt spray corrosion. More suitable sealing designs and materials are needed to effectively reduce the risk of salt spray entering the interior and maintain good sealing performance.
[0039] Based on this, this application proposes a compressor 100 for a vehicle 200, in which the cover 20 and the housing 10 are bonded and sealed by an adhesive layer 30, so that chemicals in the salt spray environment are not easily corroded by the adhesive layer 30, the cover 20 and the housing 10, nor are they easily allowed to enter the receiving cavity 202 and corrode the electronic control structure. Furthermore, by setting an adhesive groove 203, the adhesive layer 30 is not easily overflowed or incompletely coated during the assembly process, thereby improving the sealing effect.
[0040] The following description, with reference to the accompanying drawings, describes a compressor 100 for a vehicle 200 according to an embodiment of the present invention. In this embodiment, the compressor 100 may be a horizontal compressor or a vertical compressor, and may be a single-cylinder single-exhaust compressor, a single-cylinder double-exhaust compressor, a twin-cylinder compressor, etc.
[0041] Reference Figures 1-3 As shown, the compressor 100 for a vehicle 200 according to an embodiment of the present invention may include: a housing 10 and a cover 20.
[0042] Specifically, the housing 10 has a mounting cavity 102 for mounting a motor and a compression mechanism, and a cover 20 is provided on one end of the housing 10 and cooperates with the housing 10 to define a receiving cavity 202 for accommodating an electronic control structure.
[0043] An electric motor can drive a compression mechanism to compress refrigerant; an electronic control system can be connected to the motor to control its operating state, thereby controlling the operation of the compression mechanism. For example, the compression mechanism may include a cylinder with a cylinder chamber and a vane slot. An eccentrically rotating piston is located within the cylinder chamber, and a reciprocating vane is located within the vane slot. One end of the vane abuts against the outer peripheral wall of the piston. The vane is movably positioned in the vane slot, and its tip (the end closest to the cylinder center) abuts against the outer peripheral wall of the piston. The piston can roll along the inner wall of the corresponding cylinder chamber. Under the action of spring force or gas force, the tip of the sliding vane can always stop against the outer peripheral wall of the piston. When the piston rotates in the cylinder chamber, the sliding vane moves in the sliding vane groove, so that the piston and the sliding vane cooperate to divide the cylinder chamber into an intake chamber and an exhaust chamber. The cylinder has an intake port communicating with the intake chamber and an exhaust port communicating with the exhaust chamber. In the compressor 100, the piston can be sleeved on the eccentric part of the crankshaft of the compressor 100. The motor drives the crankshaft to rotate, and the piston, driven by the crankshaft, is close to the inner wall of the cylinder chamber and rolls along the inner wall of the cylinder chamber to compress the refrigerant, so that the refrigerant enters the intake chamber through the intake port. The piston rolls along the inner wall of the cylinder chamber to compress the refrigerant. The refrigerant continuously heats up and pressurizes, and enters the exhaust chamber, and then is discharged from the cylinder chamber through the exhaust port.
[0044] The electrical control structure is located in the receiving cavity 202 and is electrically connected to the motor. Thus, while ensuring a reliable connection between the electrical control structure and the motor for reliable motor control, the electrical control structure is isolated from and does not come into contact with the refrigerant, making it less likely to affect the operation of the electrical control structure. The cover 20 and the shell 10 can provide a certain degree of shielding and protection for the electrical control structure.
[0045] In addition, such as Figure 1 and Figure 2 As shown, one end of the housing 10 has a first sealing surface 101, and the cover 20 has a second sealing surface 201. The second sealing surface 201 surrounds the receiving cavity 202, and the second sealing surface 201 and the first sealing surface 101 are bonded and sealed together by an adhesive layer 30. At least one of the first sealing surface 101 and the second sealing surface 201 is provided with an adhesive groove 203, which extends circumferentially along the receiving cavity 202. The adhesive layer 30 includes a first sealing portion 31 and a second sealing portion 32. The first sealing portion 31 is located within the adhesive groove 203, and the second sealing portion 32 is bonded to the first sealing surface 101 and the second sealing surface 201.
[0046] Compared to a sealing gasket, the adhesive layer 30 can form an adhesive bond with the cover 20 and the housing 10, thus reducing the likelihood of gaps between them. The adhesive layer 30 has a certain degree of viscosity and fluidity, and its structure is less prone to micro-defects or cracks. This improves the effectiveness of preventing chemicals from gaseous, liquid, dusty, or salt spray environments from entering the cavity 202 through gaps, and reduces the risk of corrosion damage to the sealing surface caused by chemicals. Furthermore, the adhesive layer 30 is not easily corroded or penetrated by chemicals in salt spray environments, and its sealing performance is less likely to deteriorate or fail, which helps protect the normal operation of the cover 20, the housing 10, and the electrical control structure within the cavity 202.
[0047] Furthermore, by setting the glue groove 203, at least one side of the bonding surface of the formed glue layer 30 is made into a tortuous surface, which increases the bonding area, improves the bonding and sealing effect, and makes it less prone to sealing failure. During the assembly process, the glue groove 203 can also play a certain positioning and limiting role. Specifically, glue can be applied into the glue groove 203 and made to extend a certain distance above the groove opening of the glue groove 203. Then, the cover 20 is connected to the housing 10 and the extended part of the glue is squeezed to make the glue flow between the first sealing surface 101 and the second sealing surface 201, thereby forming the connected first sealing part 31 and second sealing part 32. The continuity of the glue layer 30 and the connection effect between different parts are better, which helps to reduce sealing defects. Moreover, the size and position control of the glue layer 30 are better, and the problem of glue overflow or incomplete coating is less likely to occur.
[0048] According to the present invention, the compressor 100 for vehicle 200 uses an adhesive layer 30 to bond the cover 20 and the housing 10, making it difficult for chemicals in the salt spray environment to corrode the adhesive layer 30, the cover 20 and the housing 10, and also making it difficult for them to enter the receiving cavity 202 and corrode the electrical control structure. This effectively solves the problem of salt spray corrosion and penetration. Furthermore, by setting an adhesive groove 203, the adhesive layer 30 is less likely to overflow or be incompletely coated during the assembly process, thus improving the sealing effect.
[0049] In some embodiments, such as Figure 5 As shown, the depth of the glue groove 203 is greater than or equal to 0.3 mm and less than or equal to 2 mm, for example... Figure 5 As shown, 0.3mm≤H1≤2mm.
[0050] Within the aforementioned value range, the depth of the glue tank 203 is sufficiently large to improve the anti-overflow effect of glue; and the amount of glue that the glue tank 203 can hold is not too large, thus avoiding material waste. In some specific embodiments, the depth of the glue tank 203 can be 0.3mm, 0.5mm, 1mm, 1.5mm, and 2mm, etc.
[0051] In some embodiments of this utility model, the glue groove 203 is spaced apart from the inner edge of the first sealing surface 101, and the glue groove 203 is spaced apart from the outer edge of the first sealing surface 101; the glue groove 203 is spaced apart from the inner edge of the second sealing surface 201, and the glue groove 203 is spaced apart from the outer edge of the first sealing surface 101.
[0052] Therefore, the glue tank 203 has only one side opening. Before the cover 20 is connected to the housing 10, the glue in the glue tank 203 is not likely to overflow from the inside or outside of the glue tank 203, thus preventing glue overflow. This allows the glue to flow along the required path during the connection of the cover 20 and the housing 10 to form the first sealing part 31 and the second sealing part 32, improving the continuity and bonding effectiveness of the glue layer 30.
[0053] In some embodiments, the distance between the glue groove 203 and the inner edge of the first sealing surface 101 is greater than or equal to 1 mm; the distance between the glue groove 203 and the outer edge of the first sealing surface 101 is greater than or equal to 1 mm; and the distance between the glue groove 203 and the inner edge of the second sealing surface 201 is greater than or equal to 1 mm, for example... Figure 5 As shown, H2 ≥ 1mm; the distance between the glue groove 203 and the outer edge of the second sealing surface 201 is greater than or equal to 1mm. In other words, the distance between the glue groove 203 and the edge (inner edge or outer edge) of the sealing surface (first sealing surface 101 or second sealing surface 201) is greater than or equal to 1mm.
[0054] In the description of this application, the inner and outer directions refer to the directions closer to the receiving cavity 202 and away from the receiving cavity 202 in a plane parallel to the first sealing surface 101 and the second sealing surface 201. For example, the inner edge of the first sealing surface 101 refers to the edge of the first sealing surface 101 that is closer to the receiving cavity 202, and the outer edge of the first sealing surface 101 refers to the edge of the first sealing surface 101 that is away from the receiving cavity 202.
[0055] If the distance between the glue groove 203 and the edge of the sealing surface is too small, it will not only result in an insufficient sealing dimension in both the inner and outer directions, affecting sealing reliability and lifespan, but also cause glue to easily overflow from the edge of the sealing surface during the connection of the cover 20 and the housing 10 and the pressing of the glue. For example, overflow from the inner edge into the receiving cavity 202 may interfere with the electrical control structure, while overflow from the outer edge into the outer surface of the compressor 100 may cause irregularities in the appearance of the compressor 100, increasing the need for shaping processes. Within the above-mentioned range, it is beneficial for the sealing dimension of the formed glue layer 30 to be large enough to improve the sealing effect and to solve the glue overflow problem.
[0056] In some specific embodiments, the distance between the glue groove 203 and the edge of the sealing surface can be 1mm, 2mm, and 3mm, etc.
[0057] According to some embodiments of this utility model, such as Figures 3-5 As shown, the housing 10 is provided with a first connecting hole, and the cover 20 is provided with a second connecting hole 204. Fasteners are inserted through the first connecting hole and the second connecting hole 204 to connect the housing 10 and the cover 20. The first connecting hole and the second connecting hole 204 are located outside the area enclosed by the glue groove 203.
[0058] Fasteners can be bolts, screws, clips, etc. By passing fasteners through the first and second connecting holes 204, the fasteners can provide a certain preload force to the housing 10 and the cover 20, thereby providing a moving pressing force to the first sealing surface 101 and the second sealing surface 201. This allows the first sealing surface 101 and the second sealing surface 201 to press the adhesive layer 30, thereby improving the sealing effect and sealing life of the adhesive layer 30 on the first sealing surface 101 and the second sealing surface 201, and improving the connection strength between the housing 10 and the cover 20.
[0059] In addition, the first connecting hole and the second connecting hole 204 are located within the area enclosed by the adhesive groove 203, so that the adhesive layer 30 is at least partially located on the side of the first connecting hole and the second connecting hole 204 near the receiving cavity 202, thereby separating the first connecting hole and the second connecting hole 204 from the receiving cavity 202 and improving the sealing effect of the receiving cavity 202.
[0060] In some embodiments, the distance between the glue groove 203 and the first connecting hole is greater than or equal to 1 mm; the distance between the glue groove 203 and the second connecting hole 204 is greater than or equal to 1 mm, for example... Figure 5 As shown, H3 ≥ 1 mm.
[0061] If the distance between the connecting hole (first connecting hole or second connecting hole 204) and the glue groove 203 is too small, the glue in the glue groove 203 will easily flow into the connecting hole during the assembly process. This will not only affect the size of the formed glue layer 30 and the bonding and sealing area, but the glue flowing into the connecting hole will also have an adverse effect on the subsequent assembly of fasteners.
[0062] Within the aforementioned value range, the effective size of the adhesive seal is increased, improving the sealing effect and salt spray resistance, and making fastener assembly easier and improving the assembly effect. In some specific embodiments, the distance between the adhesive groove 203 and the first connecting hole can be 1mm, 1.2mm, 1.5mm, and 2mm, etc.; the distance between the adhesive groove 203 and the second connecting hole 204 can be 1mm, 1.2mm, 1.5mm, and 2mm, etc.
[0063] In some embodiments of this utility model, the distance between the second sealing part 32 and the inner edge of the first sealing surface 101 is less than or equal to 1 mm, and the distance between the second sealing part 32 and the outer edge of the first sealing surface 101 is less than or equal to 1 mm.
[0064] In this configuration, the inner edge of the second sealing part 32 can be located outside the inner edge of the first sealing surface 101, so that the second sealing part 32 will not enter the receiving cavity 202 and interfere with the electrical control structure. Furthermore, if the distance between the second sealing part 32 and the inner edge of the first sealing surface 101 is too small, the bonding sealing distance between the second sealing part 32 and the first sealing surface 101 and the second sealing surface 201 will be too short. A distance of less than or equal to 1 mm can improve the sealing effect and better solve the salt spray corrosion problem. Alternatively, the inner edge of the second sealing part 32 can be flush with the inner edge of the first sealing surface 101, in which case the distance is zero, and both the sealing and anti-interference effects are good. Or, the inner edge of the second sealing part 32 can be located inside the inner edge of the first sealing surface 101, in which case the distance is less than or equal to 1 mm, improving the sealing effect while minimizing interference between the second sealing part 32 and the electrical control structure.
[0065] Furthermore, the outer edge of the second sealing part 32 can be located inside the outer edge of the first sealing surface 101, so that the second sealing part 32 is not exposed, and the appearance of the compressor 100 is more regular; and a spacing of less than or equal to 1 mm can improve the sealing effect and better solve the salt spray corrosion problem. Alternatively, the outer edge of the second sealing part 32 can be flush with the outer edge of the first sealing surface 101, in which case the spacing is zero, and both the sealing effect and regularity are good. Or, the outer edge of the second sealing part 32 can be located outside the outer edge of the first sealing surface 101, in which case the spacing is less than or equal to 1 mm, which improves the sealing effect while minimizing the impact of the second sealing part 32 on the appearance regularity of the compressor 100.
[0066] In some specific embodiments, the distance between the second sealing part 32 and the inner edge of the first sealing surface 101 can be 1 mm, 0.8 mm, 0.5 mm and 0.3 mm, etc.; the distance between the second sealing part 32 and the outer edge of the first sealing surface 101 can be 1 mm, 0.8 mm, 0.5 mm and 0.3 mm, etc.
[0067] It is worth noting that during assembly, adhesive can be applied first to the glue groove 203, with the adhesive portion extending above the groove opening. Then, the cover 20 is connected to the housing 10, and the extended portion of the adhesive is squeezed to allow it to flow between the first sealing surface 101 and the second sealing surface 201, forming a second sealing portion 32 for large-area bonding. The relative position and size of the final second sealing portion 32 and the first sealing surface 101 can be adjusted by adjusting the height of the adhesive above the glue groove 203 after application, resulting in better bonding and sealing performance and improved appearance regularity. In some embodiments, after the cover 20 is connected to the housing 10, the portion of the second sealing portion 32 extending beyond the outer edge of the first sealing surface 101 can be shaped to ensure that the final distance between the second sealing portion 32 and the outer edge of the first sealing surface 101 is less than or equal to 1 mm.
[0068] In some embodiments of this utility model, such as Figures 3-5 As shown, the distance between the second sealing part 32 and the inner edge of the second sealing surface 201 is less than or equal to 1 mm; the distance between the second sealing part 32 and the outer edge of the second sealing surface 201 is less than or equal to 1 mm.
[0069] Similarly, the inner edge of the second sealing part 32 can be located outside the inner edge of the second sealing surface 201, or the inner edge of the second sealing part 32 can be flush with the inner edge of the second sealing surface 201, or the inner edge of the second sealing part 32 can be located inside the inner edge of the second sealing surface 201. The outer edge of the second sealing part 32 can be located inside the outer edge of the second sealing surface 201, or the outer edge of the second sealing part 32 can be flush with the outer edge of the second sealing surface 201, or the outer edge of the second sealing part 32 can be located outside the outer edge of the second sealing surface 201.
[0070] Within the above-mentioned range of values, the area of the second sealing part 32 that adheres to the first sealing surface 101 and the second sealing surface 201 is large enough to improve the sealing effect and the anti-salt spray penetration effect, and is also conducive to improving the appearance regularity of the compressor 100, so that the second sealing part 32 is less likely to interfere with the electronic control structure.
[0071] In some specific embodiments, the distance between the second sealing part 32 and the inner edge of the second sealing surface 201 can be 1 mm, 0.8 mm, 0.5 mm and 0.3 mm, etc.; the distance between the second sealing part 32 and the outer edge of the second sealing surface 201 can be 1 mm, 0.8 mm, 0.5 mm and 0.3 mm, etc.
[0072] For example Figure 2 As shown, the distance between the second sealing part 32 and the inner edge of the first sealing surface 101 is zero, and the distance between the second sealing part 32 and the outer edge of the first sealing surface 101 is zero; and the distance between the second sealing part 32 and the inner edge of the second sealing surface 201 is zero, and the distance between the second sealing part 32 and the outer edge of the second sealing surface 201 is zero.
[0073] In some embodiments of this utility model, such as Figure 2 As shown, there is only one adhesive groove 203, which simplifies the structure while improving the bonding and sealing effect. In some other embodiments of this utility model, there can be multiple adhesive grooves 203, which is more conducive to solving the problems of overflowing adhesive and incomplete coating.
[0074] In some embodiments, a plurality of adhesive grooves 203 may be arranged at intervals along a direction away from the receiving cavity 202. That is, in any two adjacent adhesive grooves 203, one adhesive groove 203 is located within the area enclosed by the other adhesive groove 203. Thus, a multi-layered nested adhesive groove 203 is formed in the inward and outward directions to further improve the anti-overflow effect of adhesive, and adhesive can be applied at multiple locations, making the dimensions of the second sealing part 32 formed more flexible and the continuity better in the inward and outward directions.
[0075] In embodiments where there are multiple glue grooves 203, the multiple glue grooves 203 may be evenly disposed on the first sealing surface 101, or evenly disposed on the second sealing surface 201, or partially disposed on the first sealing surface 101 and partially disposed on the second sealing surface 201.
[0076] In some specific embodiments, the plurality of adhesive grooves 203 include a first adhesive groove 203 and a second adhesive groove 203. The first adhesive groove 203 is disposed on the first sealing surface 101, and the second adhesive groove 203 is disposed on the second sealing surface 201. The projections of the first adhesive groove 203 and the second adhesive groove 203 on the first sealing surface 101 are at least partially offset. In other words, the first adhesive groove 203 and the second adhesive groove 203 are at least partially offset in the inward and outward directions. As a result, the adhesive in the first adhesive groove 203 and the second adhesive groove 203 can form a coating at multiple locations in the inward and outward directions. During the connection between the cover 20 and the housing 10, the area of adhesive flowing in the inward and outward directions is larger, and there is sufficient adhesive in both the area near the receiving cavity 202 and the area away from the receiving cavity 202, thereby improving the continuity of the second sealing part 32.
[0077] In some embodiments, the adhesive layer 30 is epoxy resin adhesive. Epoxy resin adhesive has good adhesion and corrosion resistance, and is not easily corroded by chemicals in a salt spray environment, thus affecting the sealing effect. Furthermore, epoxy resin adhesive has more suitable flowability during assembly, allowing the epoxy resin adhesive applied in the adhesive groove 203 to flow fully and continuously between the first sealing surface 101 and the second sealing surface 201 under the extrusion pressure of the cover 20 and the housing 10, forming a continuous adhesive layer 30. The first sealing part 31 and the second sealing part 32 are less likely to have breaks or gaps that affect the sealing effect, and the effect of preventing salt spray from entering the receiving cavity 202 is good.
[0078] In some embodiments of this utility model, such as Figure 1 As shown, the housing 10 includes a high-pressure housing, a low-pressure housing 11 and a support. The support is located between the high-pressure housing and the low-pressure housing 11. The support and the low-pressure housing 11 cooperate to define a low-pressure chamber, and the support and the high-pressure housing cooperate to define a high-pressure chamber.
[0079] The motor can be used to drive the compressor mechanism to compress the refrigerant. At this time, the low-pressure chamber provides space for the motor. In this way, the bracket can isolate the high temperature and high pressure gas inside the housing 10 from the thermal impact on the motor, reduce the risk of motor performance degradation or even damage due to overheating, thereby helping to reduce the operating temperature of the motor and reduce the heat dissipation burden. This not only extends the service life of the motor, but also improves the working stability and reliability of the compressor 100, and reduces the risk of compressor 100 shutdown caused by motor failure.
[0080] Furthermore, the cover 20 is located on the side of the low-pressure housing 11 facing away from the support, and the cover 20 and the low-pressure housing 11 cooperate to define the receiving cavity 202. Thus, the receiving cavity 202 is adjacent to the low-pressure cavity and relatively far from the high-pressure cavity. When the refrigerant flows through the low-pressure cavity of the low-pressure housing 11, the temperature of the low-pressure housing 11 is relatively low. Since the receiving cavity 202 is adjacent to the low-pressure cavity, its temperature is also relatively low, which facilitates cooling of the electronic control structure and is beneficial for heat dissipation.
[0081] In some embodiments, the compressor 100 uses carbon dioxide as the refrigerant, thus the compressor 100 can be a carbon dioxide compressor. For example, carbon dioxide has relatively high suction and discharge pressures when used as a refrigerant, and it also has good thermodynamic properties. Therefore, when the same cooling capacity is required, using carbon dioxide as the refrigerant reduces the volume required for the compression chamber of the compressor 100, allowing for a smaller volume and thus reducing the overall size and weight of the compressor 100. Furthermore, the compressor 100 using carbon dioxide can operate over a wider pressure range, exhibiting stable performance whether performing initial compression under low pressure or deep compression under high pressure. Therefore, the compressor 100 of this embodiment facilitates obtaining an optimized compression ratio, provides efficient cooling performance in refrigeration systems, reduces energy consumption, and improves energy utilization.
[0082] While achieving a high compression ratio using a carbon dioxide compressor, the compressor 100 may experience abnormal phenomena such as surge and vibration, affecting the normal operation of the system. Furthermore, a high compression ratio can also lead to increased pressure fluctuations in the system, impacting the normal operation of other equipment. Therefore, this application improves the sealing structure of the compressor 100's receiving cavity 202 to mitigate the impact of vibration caused by using carbon dioxide as the refrigerant to achieve a high compression ratio on the seal.
[0083] like Figure 6As shown, the vehicle 200 according to an embodiment of the present invention includes a compressor 100 for the vehicle 200 according to an embodiment of the present invention. Since the compressor 100 for the vehicle 200 has the aforementioned beneficial technical effects, the vehicle 200 according to an embodiment of the present invention, by bonding the cover 20 and the housing 10 with an adhesive layer 30, prevents chemicals in the salt spray environment from easily corroding the adhesive layer 30, the cover 20, and the housing 10, and also prevents them from easily entering the receiving cavity 202 and corroding the electrical control structure, effectively solving the problem of salt spray corrosion and penetration. Furthermore, by providing an adhesive groove 203, the adhesive layer 30 is less likely to overflow or be incompletely coated during assembly, improving the sealing effect.
[0084] It is worth noting that the specific type of vehicle 200 referred to in this application is not limited. For example, vehicle 200 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, range-extended electric vehicles, solar electric vehicles, gas fuel vehicles (such as hydrogen engine vehicles), or biofuel vehicles (such as vehicles powered by ethanol, biodiesel, etc.).
