Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a compressor, an air conditioner and a vehicle. Background Art

[0002] When the compressor is running, the power module in the compressor will generate heat, and there is a risk of the power module burning out due to poor heat dissipation. Summary of the invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, in the first aspect, the present invention proposes a compressor, comprising: the compressor includes a shell with a built-in motor and a controller for supplying power to the motor, the controller is connected to the shell; the controller includes a control substrate with a control circuit installed, a support and a power module, the power module includes a main body and pins; the control substrate and the power module clamp the main body, the pins are connected to the control substrate, and the control substrate, the support and the power module are formed as a whole.

[0005] The main body in the power module is electrically connected to the control substrate through pins, so that the control substrate can obtain the operating parameters of the power module and realize the control function of the power module.

[0006] When the power module is running, the power module will generate heat. Since the shell of the compressor is usually a metal shell, the heat of the power module can be transferred to the shell, and the heat of the power module can be exported through the shell to ensure the stable operation of the power module. Due to the limitation of the installation accuracy of the power module, the power module may not be in effective contact with the shell. Therefore, in the present invention, the main body is supported by a support member so that the main body can stably exchange heat with the shell.

[0007] Specifically, in one possible application, a support member can be disposed between the main body and the control substrate, and the support member supports the main body so that the support member can press the main body against the shell, thereby making the main body in close contact with the shell. When the power module is running, the heat on the main body is dissipated through the shell.

[0008] By supporting the main body with the support member, the heat dissipation stability of the power module can be improved, the power module can be prevented from burning due to poor heat dissipation, and the operation stability of the power module can be ensured.

[0009] Moreover, the main body is supported by the supporting member, so that the main body is not easy to shake, which can improve the installation stability of the power module, thereby ensuring that the pins are stably connected to the control substrate.

[0010] In addition, the compressor in the above technical solution provided by the present invention may also have the following additional technical features:

[0011] In the above technical solution, a first mounting hole is provided on the control substrate, a second mounting hole is provided on the support member, and a third mounting hole is provided on the main body; the compressor also includes: a locking member, which passes through the first mounting hole, the second mounting hole and the third mounting hole, and installs the controller in the storage cavity of the shell.

[0012] In this technical solution, the control substrate and the support member are locked on the housing by a locking member, so the position of the support member is not easily changed, so that the support member can stably support the main body, thereby ensuring the heat dissipation effect of the power module.

[0013] Specifically, a first mounting hole is formed on the control substrate, a second mounting hole is formed on the support member, and a third mounting hole is formed on the main body. After the locking member passes through the first mounting hole, the second mounting hole and the third mounting hole, the relative positions of the support member, the control substrate and the power module are fixed, thereby ensuring the stability of the relative positions of the support member, the control substrate and the power module. The locking member is locked to the shell, thereby locking the support member, the control substrate and the power module to the shell through the locking member.

[0014] Exemplarily, the locking member is a screw, and a threaded hole is provided on the housing so as to connect the screw with the threaded hole. Alternatively, the locking member is a pin, and a pin hole is provided on the housing so that the pin can be inserted into the pin hole.

[0015] In any of the above technical solutions, the supporting member includes an elastic member, and when the elastic member is located between the main body and the control substrate, the elastic member is in an elastically deformed state.

[0016] In this technical solution, the support member can be made of an elastic material. The support member made of the elastic material is softer in texture. Therefore, when the support member is located between the main body and the control substrate, the elastic support member is not easy to cause damage to the main body and the control substrate, thereby reducing the damage rate of the main body and the control substrate.

[0017] When the elastic member is located between the main body and the control substrate, the elastic member is compressed, so the elastic member is in an elastic deformation state. At this time, the elastic member has a tendency to push the main body, so that the main body is pushed toward the shell, ensuring the contact stability between the main body and the shell, thereby improving the heat dissipation stability of the main body.

[0018] Exemplarily, the elastic member is a rubber part or a silicone part, and the elastic member may also be a compression spring.

[0019] In any of the above technical solutions, a portion of the elastic member passes through the first mounting hole, and a portion of the elastic member that passes through the first mounting hole is located between the locking member and the control substrate.

[0020] In this technical solution, a part of the elastic member is located between the end of the locking member and the control substrate, and another part of the elastic member is located between the control substrate and the main body. The part of the elastic member located between the control substrate and the main body pushes the main body so that the main body and the shell are stably fitted. The part of the elastic member located between the end of the locking member and the control substrate protects the control substrate. Since the elastic member is soft, when the locking member is tightened, the elastic member buffers the end of the locking member and the control substrate, so that the end of the locking member is not easy to damage the control substrate, thereby reducing the damage rate of the control substrate.

[0021] The elastic member is relatively soft, and a portion of the elastic member can be passed through the first mounting hole, so that the elastic member can be arranged on both sides of the control substrate. There is no need to arrange two independent elastic members, which can reduce the number of parts and components and avoid separation of the elastic member and the control substrate.

[0022] In any of the above technical solutions, the support member includes: a copper support member or a copper alloy support member, and the support member is welded to the control substrate.

[0023] In any of the above technical solutions, the support member includes: an aluminum support member or an aluminum alloy support member, and the support member is welded to the control substrate; the compressor also includes: a tin plating layer, which is arranged on the surface of the aluminum support member or the aluminum alloy support member.

[0024] In any of the above technical solutions, a welding part is provided on the control substrate, the welding part includes a copper welding part or a copper-plated welding part, and the welding part is used to weld with the support. In any of the above technical solutions, the support is annular, and the pin is located in the annular area surrounded by the support.

[0025] The support is located between the control substrate and the main body, and the support is annular, so the support can enclose the pin inside, and the support plays a protective role for the pin. Since there is a gap between the main body and the control substrate, the support protects the pin and can prevent the pin from being bumped by other components, thereby ensuring the connection stability between the pin and the control substrate. The support can realize both the supporting function and the protective function, thereby realizing the function of one object with multiple uses.

[0026] In any of the above technical solutions, the support member includes a plurality of stacked support parts, and among two adjacent support parts, one support part is provided with a protrusion, and the other support part is provided with a groove, and the protrusion is inserted into the groove.

[0027] In this technical solution, the support member has a multi-layer structure, and the number of support parts used can be determined according to the length of the gap between the main body and the control substrate. For different gap conditions, changing the number of support parts used can meet the support requirements of the main body, and there is no need to process support members of specific thickness, which can improve the versatility of the support member.

[0028] The adjacent two side support parts can be connected to each other to prevent the two adjacent layers of support parts from sliding relative to each other. For example, a protrusion is provided on one side of the support part, and a groove is provided on the other side of the support part, and the protrusion on one support part can be inserted into the groove of the adjacent support part.

[0029] In a second aspect, the present invention proposes an air conditioner, comprising: a compressor as in any of the above technical solutions.

[0030] In a third aspect, the present invention proposes a vehicle, comprising: a compressor as in any of the above technical solutions; or an air conditioner as in the above technical solutions.

DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] Refer to the following Figures 1 to 12 A compressor, an air conditioner, and a vehicle provided according to some embodiments of the present invention are described.

[0050] Combination Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of the present invention, a compressor is proposed, including: a housing 100 and a controller 600, the controller 600 is connected to the housing 100, the housing 100 has a motor built therein, and the controller 600 is used to supply power to the motor. The controller 600 includes: a control substrate 200, a power module 300 and a support 400. A control circuit is mounted on the control substrate 200, and the power module 300 includes a main body 310 and a pin 320. The control substrate 200 and the power module 300 clamp the main body 310, and the pin 320 is connected to the control substrate 200, and the control substrate 200, the support 400 and the power module 300 are formed as a whole.

[0051] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the main body 310 in the power module 300 is electrically connected to the control substrate 200 through the pins 320 , so that the control substrate 200 can obtain the operating parameters of the power module 300 and realize the control function of the power module 300 .

[0052] When the power module 300 is running, the power module 300 generates heat. Since the housing 100 of the compressor is usually a metal housing 100, the heat of the power module 300 can be transferred to the housing 100, and the heat of the power module 300 is extracted through the housing 100 to ensure the stable operation of the power module 300. Due to the limitation of the installation accuracy of the power module 300, the power module 300 may not be in effective contact with the housing 100. Therefore, in the present invention, the main body 310 is supported by the support member 400 so that the main body 310 can stably exchange heat with the housing 100.

[0053] Specifically, in a possible application, the support member 400 can be disposed between the main body 310 and the control substrate 200, and the support member 400 supports the main body 310, so that the support member 400 can press the main body 310 against the shell 100, thereby making the main body 310 in close contact with the shell 100, and when the power module 300 is running, the heat on the main body 310 is discharged through the shell 100.

[0054] In a possible application, the support member 400 can be set between the main body 310 and the shell 100, and the support member 400 supports the main body 310. The main body 310 is not easy to shake relative to the support member 400. At this time, the support member 400 is in close contact with the shell 100, and the main body 310 is in close contact with the support member 400. In this case, the support member 400 made of heat-conductive material can be selected to make the main body 310, and the heat of the main body 310 can be conducted to the shell 100 through the support member 400, thereby achieving heat dissipation of the main body 310.

[0055] In a possible application, a portion of the support member 400 can be set between the main body 310 and the control substrate 200, and another portion of the support member 400 can be set between the main body 310 and the shell 100. The support member 400 can also support the main body 310 to prevent the main body 310 from shaking, thereby stably dissipating heat for the main body 310.

[0056] By supporting the main body 310 with the support member 400 , the heat dissipation stability of the power module 300 can be improved, the power module 300 can be prevented from being burned due to poor heat dissipation, and the operation stability of the power module 300 can be ensured.

[0057] Furthermore, the main body 310 is supported by the support member 400 , so that the main body 310 is not prone to shaking, and the installation stability of the power module 300 can be improved, thereby ensuring that the pins 320 are stably connected to the control substrate 200 .

[0058] In a possible application, the housing 100 is provided with an electric control cavity, and the control substrate 200 is fixed in the electric control cavity by screws. The control substrate 200 is provided with welding holes corresponding to the pins 320, and the pins 320 are fixed to the welding holes on the control substrate 200 by welding.

[0059] like Figure 2 As shown, in the above embodiment, the control substrate 200 is provided with a first mounting hole 210, the support member 400 is provided with a second mounting hole 430, and the main body 310 is provided with a third mounting hole 311. The compressor further includes: a locking member 500, which passes through the first mounting hole 210, the second mounting hole 430 and the third mounting hole 311, and mounts the controller 600 in the receiving cavity of the housing 100.

[0060] In this embodiment, the control substrate 200 and the support member 400 are locked on the housing 100 by the locking member 500. Therefore, the position of the support member 400 is not easy to change, so that the support member 400 can stably support the main body 310, thereby ensuring the heat dissipation effect of the power module 300.

[0061] Specifically, a first mounting hole 210 is formed on the control substrate 200, a second mounting hole 430 is formed on the support member 400, and a third mounting hole 311 is formed on the main body 310. After the locking member 500 passes through the first mounting hole 210, the second mounting hole 430 and the third mounting hole 311, the relative positions of the support member 400, the control substrate 200 and the power module 300 are fixed, thereby ensuring the stability of the relative positions of the support member 400, the control substrate 200 and the power module 300. The locking member 500 is locked to the housing 100, thereby locking the support member 400, the control substrate 200 and the power module 300 to the housing 100 through the locking member 500.

[0062] For example, the locking member 500 is a screw, and a threaded hole is provided on the housing 100, so that the screw is connected to the threaded hole. Alternatively, the locking member 500 is a pin, and a pin hole is provided on the housing 100, and the pin can be inserted into the pin hole.

[0063] Combination Figure 8 , Fig. 9 and Fig.10 As shown, the support member 400 may be a columnar structure.

[0064] Combination Figure 3 and Fig.11As shown, in any of the above embodiments, the support member 400 includes an elastic member 411. When the elastic member 411 is located between the main body 310 and the control substrate 200, the elastic member 411 is in an elastically deformed state.

[0065] In this embodiment, the support member 400 can be made of an elastic material. The support member 400 made of the elastic material is softer. Therefore, when the support member 400 is located between the main body 310 and the control substrate 200, the elastic support member 400 is not easy to cause damage to the main body 310 and the control substrate 200, thereby reducing the damage rate of the main body 310 and the control substrate 200.

[0066] When the elastic member 411 is located between the main body 310 and the control substrate 200, the elastic member 411 is compressed, so the elastic member 411 is in an elastic deformation state. At this time, the elastic member 411 has a tendency to push the main body 310, so that the main body 310 is pushed toward the shell 100, ensuring the contact stability between the main body 310 and the shell 100, thereby improving the heat dissipation stability of the main body 310.

[0067] Exemplarily, the elastic member 411 is a rubber portion or a silicone portion, and the elastic member 411 may also be a compression spring.

[0068] Combination Figure 3 and Fig.11 As shown, in any of the above embodiments, a portion of the elastic member 411 passes through the first mounting hole 210 , and a portion of the elastic member 411 passing through the first mounting hole 210 is located between the locking member 500 and the control substrate 200 .

[0069] In this embodiment, a portion of the elastic member 411 is located between the end of the locking member 500 and the control substrate 200, and another portion of the elastic member 411 is located between the control substrate 200 and the main body 310. The portion of the elastic member 411 located between the control substrate 200 and the main body 310 pushes the main body 310, so that the main body 310 and the housing 100 are stably fitted. The portion of the elastic member 411 located between the end of the locking member 500 and the control substrate 200 protects the control substrate 200. Since the elastic member 411 is soft, when the locking member 500 is tightened, the elastic member 411 buffers the end of the locking member 500 and the control substrate 200, so that the end of the locking member 500 is not easy to damage the control substrate 200, thereby reducing the damage rate of the control substrate 200.

[0070] The elastic member 411 is relatively soft in texture, and a portion of the elastic member 411 can be passed through the first mounting hole 210, so that the elastic member 411 can be arranged on both sides of the control substrate 200. There is no need to arrange two independent elastic members 411, which can reduce the number of parts and components and avoid separation of the elastic member 411 and the control substrate 200.

[0071] In a possible embodiment, the support member 400 includes: a copper support member or a copper alloy support member.

[0072] The support member 400 is made of copper or copper alloy, which can facilitate stable welding of the control substrate 200 and the support member 400 .

[0073] In a possible embodiment, the support member 400 includes: an aluminum support member or an aluminum alloy support member, the support member 400 is welded to the control substrate 200, and the compressor further includes: a tin plating layer, the tin plating layer is arranged on the surface of the aluminum support member or the aluminum alloy member.

[0074] By providing a tin-plated layer on the surface of the aluminum support member or the aluminum alloy member, the connection stability between the support member 400 and the control substrate 200 is improved.

[0075] In a possible application, the support member 400 is made of aluminum or aluminum alloy, and the surface of the aluminum alloy has a tin-plated layer, which can also improve the welding stability of the support member 400 .

[0076] The first end of the support member 400 may be fixed to the control substrate 200 by welding or bonding, and the second end of the support member 400 is in contact with the main body 310 .

[0077] In a possible embodiment, a welding portion 220 is provided on the control substrate 200 . The welding portion 220 includes a copper welding portion or a copper-plated welding portion. The welding portion 220 is used to be welded to the support member 400 .

[0078] A copper alloy or copper-plated pad is disposed at a position on the control substrate 200 corresponding to the support member 400 to ensure welding stability between the control substrate 200 and the support member 400 .

[0079] In any of the above embodiments, the support member 400 is annular, and the pins 320 are located in the annular area surrounded by the support member 400 .

[0080] The support member 400 is located between the control substrate 200 and the main body 310, and the support member 400 is annular, so the support member 400 can enclose the pin 320 inside, and the support member 400 plays a protective role on the pin 320. Since there is a gap between the main body 310 and the control substrate 200, the support member 400 protects the pin 320, which can prevent the pin 320 from being bumped by other components, thereby ensuring the connection stability between the pin 320 and the control substrate 200. The support member 400 can realize both the supporting function and the protective function, thereby realizing the function of one object with multiple uses.

[0081] like Fig.12As shown, in any of the above embodiments, the support member 400 includes a plurality of stacked support portions 440 , and in two adjacent support portions 440 , a protrusion 450 is provided on one support portion 440 , and a groove 460 is provided on the other support portion 440 , and the protrusion 450 is inserted into the groove 460 .

[0082] The support member 400 has a multi-layer structure, and the number of support parts 440 used can be determined according to the length of the gap between the main body 310 and the control substrate 200. For different gap conditions, changing the number of support parts 440 used can meet the support requirements of the main body 310. There is no need to process the support member 400 of a specific thickness, which can improve the versatility of the support member 400.

[0083] The adjacent two side support parts 440 can be connected to each other to prevent the two adjacent layers of support parts 440 from sliding relative to each other. For example, a protrusion 450 is provided on one side of the support part 440, and a groove 460 is provided on the other side of the support part 440, and the protrusion 450 on one support part 440 can be inserted into the groove 460 of the adjacent support part 440.
