Description

[0001] This application is a divisional application of Chinese patent application filed on May 17, 2021, with application number “202110536073.2” and invention title “Cover assembly, stator, motor, compressor and vehicle”. Technical Field

[0002] This invention relates to the field of motor technology, and more specifically, to a cover plate assembly, a stator, a motor, a compressor, and a vehicle. Background Technology

[0003] In related technologies, the motor leads are electrically connected to the wiring terminals of other components. Due to the lack of a device to seal the connection between the leads and the wiring terminals, media such as oil and refrigerant can easily enter the connection between the leads and the wiring terminals, causing a sharp drop in the insulation resistance of the motor stator and affecting the performance of the product. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, a first aspect of the present invention provides a cover plate assembly.

[0006] A second aspect of the invention provides a stator.

[0007] A third aspect of the present invention provides an electric motor.

[0008] A fourth aspect of the present invention provides a compressor.

[0009] The fifth aspect of the present invention provides a vehicle.

[0010] In view of this, a first aspect of the present invention provides a cover plate assembly for a motor, the motor including lead wires, the cover plate assembly including: a first housing having a first communicating portion; a second housing being detachably connected to the first housing, the first housing and the second housing enclosing a sealing cavity and a second communicating portion, both the first communicating portion and the second communicating portion communicating with the sealing cavity; wherein the second communicating portion is used for the lead wires to extend into the sealing cavity.

[0011] The present invention provides a cover plate assembly comprising a first housing and a second housing, wherein a sealing cavity and a second communicating portion are formed between the first housing and the second housing, and the first housing is provided with a first communicating portion, both of which communicate with the sealing cavity. A motor lead wire extends into the sealing cavity through the second communicating portion, and a wiring portion of a device that mates with the motor is inserted into the sealing cavity through the first communicating portion to electrically connect with the lead wire. Specifically, the first housing is a socket, and the second housing is an insulating end plate.

[0012] Since the connection between the lead wire and the terminal is located in the sealed cavity, the sealed cavity can effectively prevent external media such as oil and refrigerant from seeping into the connection between the lead wire and the terminal, thus providing a good sealing effect. This avoids the situation where the insulation resistance of the motor stator drops sharply due to the seepage of media such as oil and refrigerant into the connection between the lead wire and the terminal, which helps to ensure the performance and reliability of the motor.

[0013] Understandably, the cover plate assembly works in conjunction with the motor's insulating support. The cover plate assembly serves to fix and limit the lead wire, ensuring the proper fit between the lead wire and the motor's connection device. This prevents the lead wire from shifting and causing a break in the connection between the lead wire and the wiring terminal, providing effective structural support for the product's stability and reliability. Furthermore, the first and second housings cooperate to ensure the connection between the lead wire and the wiring terminal is located within a sealed cavity. This design prevents external forces from directly acting on the lead wire and wiring terminal, providing protection and extending the product's lifespan.

[0014] Furthermore, the first and second housings are detachably connected, facilitating the assembly and disassembly of the lead wire relative to the cover assembly, resulting in low production costs, and this arrangement also facilitates the cleaning and maintenance of the cover assembly.

[0015] The cover plate assembly according to the present invention may also have the following additional technical features:

[0016] In the above technical solution, a portion of the first housing protrudes to form a first mounting groove; a portion of the second housing protrudes to form a second mounting groove, the first mounting groove extends into the second mounting groove, and the inner wall surface of the second mounting groove and the inner wall surface of the first mounting groove enclose a sealing cavity; wherein, the protrusion direction of the first mounting groove is opposite to the protrusion direction of the second mounting groove.

[0017] In this technical solution, the first housing has a first mounting groove and the second housing has a second mounting groove. When the first housing and the second housing are connected, the first mounting groove of the first housing extends into the second mounting groove, so that the inner wall surface of the first mounting groove and the inner wall surface of the second mounting groove together form a sealing cavity for accommodating the lead wire.

[0018] The protrusion direction of the first mounting groove is opposite to that of the second mounting groove. That is, the first mounting groove and the second mounting groove are fastened together. The inner wall surface of the first mounting groove and the inner wall surface of the second mounting groove cooperate to achieve effective protection. Even if media such as oil and refrigerant seep into the cover plate assembly, the outer wall surface of the second mounting groove will also block the medium to ensure the sealing effect of the sealing cavity.

[0019] Specifically, the outer wall of the first mounting groove abuts against the inner wall of the second mounting groove to improve the sealing performance of the sealing cavity.

[0020] In any of the above technical solutions, the first housing further includes a mounting plate, a first mounting groove is located on one side of the mounting plate, a portion of the mounting plate protrudes from the side of the first mounting groove, and the top wall of the second mounting groove abuts against the portion of the mounting plate protruding from the side of the first mounting groove.

[0021] In this technical solution, by rationally designing the mating structure of the first and second housings, the first housing includes a mounting plate, and a first mounting groove is located on one side of the mounting plate. After the first and second housings are assembled, the top wall of the second mounting groove abuts against the portion of the mounting plate protruding from the side of the first mounting groove. The mating connection between the top wall of the second mounting groove and the mounting plate serves as a seal. Thus, even if media such as oil or refrigerant seep into the cover plate assembly and the accumulated height of the media is high, the media will be blocked outside the sealing cavity by the abutting top wall of the second mounting groove and the mounting plate, resulting in a good sealing effect.

[0022] Specifically, the top wall of the second mounting groove and the portion of the mounting plate protruding from the side of the first mounting groove are in surface contact. This arrangement increases the mating area and mating angle of the first and second housings, enabling sealing at multiple angles and improving the effectiveness and feasibility of the cover plate assembly's sealing.

[0023] Specifically, the top wall of the second mounting slot includes any one or a combination of the following: a plane, a curved surface, and a folded surface.

[0024] Specifically, the wall of the first recess is in contact with the peripheral wall of the lead wire.

[0025] In any of the above technical solutions, the first housing is further provided with a first baffle, the first baffle and the first mounting groove are located on the same side of the mounting plate, the first baffle is provided with a first recess, and the first recess is connected to the first mounting groove; the second housing is provided with a second baffle, the part of the second baffle corresponding to the first recess is provided with a second recess, the second recess is connected to the second mounting groove, the recesses of the first recess and the second recess are in opposite directions, and the first recess and the second recess together enclose a second connecting part.

[0026] In this technical solution, the first housing is provided with a first baffle, and the second housing is provided with a second baffle. The first baffle is provided with a first recess, and the second baffle is provided with a second recess. The recesses of the first and second recesses are in opposite directions, and the wall surfaces of both the first and second recesses are engaged with the outer peripheral wall of the lead wire. That is, the first and second recesses engage to allow the lead wire to extend into the sealed cavity.

[0027] The first and second baffles work together to achieve multiple sealing effects, which helps to improve the sealing effect of the cover assembly on the lead wire. In addition, the first and second recesses are recessed in opposite directions, that is, the first and second recesses work together to support and fix the lead wire.

[0028] In any of the above technical solutions, the first recess and the second recess cooperate to compress the lead wire located in the second connecting portion.

[0029] In this technical solution, the lead wire includes a conductor, a sleeve, and a terminal. The conductor is electrically connected to the terminal, and the sleeve is fitted over the outside of the conductor and located on one side of the terminal. A first recess and a second recess engage to compress the lead wire located within the connecting portion. The sleeve deforms under pressure, thus ensuring a tight seal between the outer wall of the sleeve and the first and second recesses. In other words, the second connecting portion has an interference fit with the lead wire.

[0030] Furthermore, since the first and second recesses are recessed in opposite directions, the lead wires can be squeezed from multiple directions and angles simultaneously to effectively prevent media such as oil and refrigerant from seeping into the cover plate assembly.

[0031] The second connecting part cooperates with the sealing cavity to achieve multiple sealing functions, which helps to improve the sealing effect of the cover plate assembly at the connection between the lead wire and the wiring part.

[0032] In any of the above technical solutions, the number of second baffles is further multiplied; wherein, along the direction from the second baffle to the first baffle, the multiple second baffles are arranged at intervals.

[0033] In this technical solution, there are multiple second baffles. By reasonably setting the cooperation structure of multiple second baffles, multiple second baffles are arranged at intervals along the direction from the second baffle to the first baffle. This setting increases the cooperation area between the second connecting part and the lead wire, so as to ensure the support and fixing effect of the second connecting part on the lead wire.

[0034] In addition, multiple second baffles are arranged at intervals, which is equivalent to defining multiple groove structures. If media such as oil and refrigerant seep into the cover plate assembly, they must pass through multiple groove structures one by one. In other words, this setting achieves multiple seals.

[0035] Specifically, the second mounting groove includes a third wall and a fourth wall, which are arranged opposite to each other and spaced apart. The outermost second baffle is connected to both the third wall and the fourth wall. In other words, the outermost second baffle forms one side wall of the second mounting groove, and the remaining second baffles are all located inside the second mounting groove.

[0036] In any of the above technical solutions, the number of first baffles is two, and multiple second baffles are located between the two first baffles.

[0037] In this technical solution, there are two first baffles. One of the two first baffles is located on one side of the multiple second baffles, and the other of the two first baffles is located on the other side of the multiple second baffles. The two first baffles and the multiple second baffles cooperate to define multiple groove structures. If media such as oil and refrigerant seep into the cover plate assembly, they must pass through the multiple groove structures one by one. In other words, this setting achieves multiple seals.

[0038] Specifically, one of the two first baffles extends into the second mounting groove, and the other of the two first baffles is located outside the second mounting groove.

[0039] In any of the above technical solutions, the first housing further includes a protrusion connected to the mounting plate. The protrusion and the first mounting groove are located on opposite sides of the mounting plate. The first connecting part is a through hole that penetrates the bottom wall of the protrusion and the first mounting groove.

[0040] In this technical solution, the first housing also includes a protrusion located on one side of the mounting plate, and a first mounting groove located on the other side of the mounting plate. The first connecting portion is a through hole that penetrates the bottom wall of the protrusion and the first mounting groove. That is, the first connecting portion extends from the sealing cavity in a direction away from the sealing cavity. In this way, media such as oil and refrigerant outside the cover plate assembly need to pass over the protrusion to enter the first connecting portion. This arrangement helps to improve the sealing effect of the cover plate assembly.

[0041] Furthermore, the first connecting part is a through hole, which can penetrate the bottom wall of the protrusion and the first mounting groove. Therefore, the wiring part of the device that is electrically connected to the motor is inserted into the through hole from top to bottom and enters the sealing cavity to be electrically connected to the lead wire in the sealing cavity.

[0042] In any of the above technical solutions, further, from the protrusion to the edge of the first housing, the mounting plate includes a first plate and a second plate; along the direction from the first housing to the second housing, the first plate is located above the second plate; wherein, the protrusion is connected to the first plate.

[0043] In this technical solution, the mounting plate includes a first plate and a second plate. The second plate is located on one side of the first plate. Along the direction from the first housing to the second housing, the first plate is located above the second plate, and the protrusion is connected to the higher first plate. In this way, media such as oil and refrigerant outside the cover assembly need to pass through the first plate and the protrusion in sequence before entering the first connecting part. This arrangement helps to improve the sealing effect of the cover assembly.

[0044] In any of the above technical solutions, further, along the direction from the first housing to the second housing, the portion of the bottom wall of the second mounting groove corresponding to the through hole is located above the portion of the bottom wall of the second mounting groove corresponding to the second connecting portion.

[0045] In this technical solution, by rationally designing the structure of the second mounting groove, the bottom wall of the second mounting groove includes a portion corresponding to the through hole and a portion corresponding to the second connecting part. The portion of the bottom wall of the second mounting groove corresponding to the through hole is located above the portion corresponding to the second connecting part. That is, the part of the lead wire used for electrical connection with the wiring part is positioned higher. Thus, even if oil or refrigerant seeps into the cover plate assembly, it will only flow to the connection point between the lead wire and the wiring part when the accumulated height of the oil or refrigerant reaches a certain value. This design effectively prevents a sharp drop in the insulation resistance of the motor stator, thus helping to ensure the performance and reliability of the motor.

[0046] In any of the above technical solutions, the cover plate assembly further includes: a first connecting part disposed on the first housing; and a second connecting part disposed on the second housing, wherein the first housing and the second housing are detachably connected through the first connecting part and the second connecting part.

[0047] In this technical solution, the cover plate assembly further includes a first connecting part and a second connecting part. The first connecting part is located in the first housing, and the second connecting part is located in the second housing. The first connecting part and the second connecting part are detachably connected, thereby achieving the purpose of detachably connecting the first housing and the second housing. This arrangement ensures the mating dimensions of the first housing and the second housing, providing effective structural support for the effectiveness and feasibility of forming a sealing cavity between the first housing and the second housing.

[0048] It is understood that the first housing and the second housing are detachably connected via a first connecting part and a second connecting part to create a sealed cavity between the first housing and the second housing. When it is necessary to disassemble the cover plate assembly, external force can be applied to the first housing and / or the second housing to overcome the bonding force between the first housing and the second housing, thereby achieving the separation of the first housing and the second housing. This structural design provides assembly reliability, facilitates installation and subsequent disassembly and maintenance, and also facilitates the adjustment and calibration of the first housing relative to the second housing during the assembly process.

[0049] In any of the above technical solutions, one of the first connecting part and the second connecting part is a snap fastener and the other is a locking part, and the snap fastener and the locking part engage with each other.

[0050] This technical solution specifically defines another connection method for the first housing and the second housing: a snap-fit ​​connection, wherein one of the first connecting part and the second connecting part is a snap-fit ​​and the other is a locking part. Specifically, the locking part is provided on the first housing and the snap-fit ​​is provided on the second housing, or the locking part is provided on the second housing and the snap-fit ​​is provided on the first housing. This facilitates quick assembly and disassembly of the first housing and the second housing.

[0051] In any of the above technical solutions, the first connecting part and the second connecting part are both threaded holes, and the cover plate assembly also includes a threaded component, which is screwed into the threaded hole.

[0052] This technical solution specifically defines another connection method for the first and second housings. The first and second housings are connected via threaded connections. This ensures a stable connection between the first and second housings while facilitating quick disassembly of both housings.

[0053] Specifically, the threaded components include screws, and both the first and second housings are provided with threaded holes, with the screws threaded into these holes. Using screw connections facilitates installation, saves costs, simplifies the production process, improves production efficiency, and also facilitates subsequent disassembly and maintenance.

[0054] In any of the above technical solutions, one of the first connecting part and the second connecting part is a limiting rib, and the other is a limiting socket, and the limiting rib can be inserted into the limiting socket.

[0055] In this technical solution, the first and second housings are designed to be connected via a matching limiting socket and a limiting rib. Specifically, matching limiting ribs and limiting sockets are provided to allow the first and second housings to be plugged together. This facilitates assembly, allows for quick disassembly and assembly of the first and second housings, and enables the first housing to be quickly positioned on the second housing by accurately locating the limiting socket.

[0056] In any of the above technical solutions, a second connecting portion is provided on the outer wall of the second mounting groove, and a first connecting portion is provided on the part of the first housing corresponding to the second connecting portion.

[0057] In this technical solution, by rationally setting the positional relationship between the first connecting part and the second connecting part, the second connecting part is provided on the outer wall of the second mounting groove, and the first housing is provided with the first connecting part, with the first connecting part and the second connecting part correspondingly arranged. Thus, after the first housing and the second housing are assembled, the first connecting part on the first housing mates with the second connecting part provided on the outer wall of the second mounting groove.

[0058] Specifically, there are multiple sealing cavities, first connecting parts, and second connecting parts. Each second mounting groove has at least one second connecting part on its outer wall, and each second connecting part is detachably connected to one first connecting part. That is, there are N sealing cavities, and consequently, there are N mating connections between the first housing and the second housing.

[0059] In any of the above technical solutions, the first housing is provided with a first guide portion, the second housing is provided with a second guide portion, and the first guide portion and the second guide portion are connected in cooperation.

[0060] In this technical solution, by rationally designing the mating structure of the first and second housings, the first housing is provided with a first guide portion, and the second housing is provided with a second guide portion. The first and second guide portions serve to guide the mating connection of the first and second housings, effectively ensuring the mating dimensions between them, thereby guaranteeing the effectiveness of the formed sealing cavity. This design simplifies the assembly process of the first and second housings, reduces the assembly difficulty, and facilitates rapid assembly and disassembly of the first and second housings.

[0061] In any of the above technical solutions, one of the first guide portion and the second guide portion is a guide post and the other is a guide hole, and the guide post can extend into the guide hole.

[0062] In this technical solution, by rationally setting the cooperative structure of the first guide part and the second guide part, the first guide part can be a guide post and the second guide part a guide hole, or the first guide part can be a guide hole and the second guide part a guide post. The guide post can extend into the guide hole. That is to say, when the first housing and the second housing are assembled, the guide post extends into the guide hole to guide the assembly of the first housing and the second housing, avoiding misalignment of the first housing and the second housing, and providing effective and reliable structural support for the effectiveness and feasibility of enclosing the sealing cavity.

[0063] In any of the above technical solutions, the cover plate assembly is further provided with a limiting part, which is located inside the sealing cavity and is used to limit the displacement of the lead wire inside the sealing cavity.

[0064] In this technical solution, the cover plate assembly is also provided with a limiting part, which is located in the sealing cavity. The limiting part is used to limit the displacement of the lead wire in the sealing cavity, so as to avoid the lead wire from shifting. This ensures the relative positional relationship between the lead wire and the first connecting part, thereby providing effective and reliable structural support for the subsequent wiring part to extend into the sealing cavity to make electrical connection with the lead wire.

[0065] In any of the above technical solutions, the limiting part further includes: a limiting groove and / or a limiting hole.

[0066] In this technical solution, the limiting part includes a limiting groove and / or a limiting hole, which can limit the displacement of the lead wire in the sealed cavity.

[0067] Specifically, the outer wall surface of the lead wire is provided with limiting protrusions, which can be inserted into limiting grooves or limiting holes. There are multiple limiting protrusions, some of which are connected to the limiting grooves and others are connected to the limiting holes.

[0068] In any of the above technical solutions, the number of limiting parts is further multiplied.

[0069] In this technical solution, there are multiple limiting parts. The multiple limiting parts increase the limiting area of ​​the cover plate assembly for restricting the movement of the lead wire, which is beneficial to improving the stability and feasibility of the cover plate assembly in fixing and limiting the lead wire.

[0070] In any of the above technical solutions, there are multiple sealing cavities, first connecting parts, and second connecting parts, with each sealing cavity connected to a first connecting part and a second connecting part.

[0071] In this technical solution, by rationally arranging a cooperative structure of multiple sealing cavities, multiple first connecting parts, and multiple second connecting parts, each sealing cavity is connected to one first connecting part and one second connecting part. The motor has multiple leads, each of which extends into a sealing cavity through a second connecting part. This arrangement ensures the relative independence of the multiple leads.

[0072] In any of the above technical solutions, the cover plate assembly is further provided with an identification part, which is located at the second connecting part.

[0073] In this technical solution, by setting an identification part, which is located at the second connecting part, the identification part has the function of indicating the type of lead wire in the sealed cavity, thus facilitating the operator to assemble and disassemble the motor.

[0074] Specifically, there are three leads, three sealing cavities, and three marking sections, with the marking sections labeled “U”, “V”, and “W” respectively.

[0075] In any of the above technical solutions, the cover plate assembly is further defined as an insulating cover plate assembly.

[0076] A second aspect of the invention provides a stator comprising a cover plate assembly as described in any of the technical solutions in the first aspect.

[0078] In the above technical solution, the stator further includes lead wires, a portion of which extends into the sealed cavity through the second connecting portion.

[0079] In this technical solution, the stator includes lead wires. The lead wires of the stator extend into the sealed cavity through the second connecting part.

[0080] In any of the above technical solutions, the lead wire further includes: a conductor; a sleeve surrounding the outside of the conductor; a terminal located on one side of the sleeve and connected to the conductor, the terminal being provided with a protrusion, the protrusion being engaged with the limiting part of the cover plate assembly.

[0081] In this technical solution, the lead wire includes a conductor, a sleeve, and a terminal. The sleeve surrounds the outside of the conductor, the terminal is located on one side of the sleeve, and the terminal is electrically connected to the conductor. The lead wire is electrically connected to the wiring part of other devices through the terminal.

[0082] Furthermore, the terminal is provided with a protrusion, and the limiting part is connected to the protrusion to restrict the displacement of the lead wire in the sealed cavity, so as to avoid the lead wire from shifting. This ensures the relative positional relationship between the lead wire and the first connecting part, thereby providing effective and reliable structural support for the subsequent wiring part to extend into the sealed cavity to make electrical connection with the lead wire.

[0124] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 23 As shown, an embodiment of the first aspect of the present invention provides a cover plate assembly 100 for a motor, the motor including lead wires 200, and the cover plate assembly 100 including a first housing 110 and a second housing 130.

[0125] The first housing 110 is provided with a first connecting portion 112, and the second housing 130 is detachably connected to the first housing 110. The first housing 110 and the second housing 130 enclose a sealing cavity and a second connecting portion 190.

[0126] Both the first connecting part 112 and the second connecting part 190 are connected to the sealing cavity, and the second connecting part 190 is used to allow the lead wire 200 to extend into the sealing cavity.

[0127] In detail, the cover assembly 100 includes a first housing 110 and a second housing 130, wherein a sealing cavity and a second communicating portion 190 are enclosed between the first housing 110 and the second housing 130, and the first housing 110 is provided with a first communicating portion 112, both of which communicate with the sealing cavity. The motor lead wire 200 extends into the sealing cavity through the second communicating portion 190, and the wiring portion 302 of the device that mates with the motor is inserted into the sealing cavity through the first communicating portion 112 to electrically connect with the lead wire 200. Specifically, the first housing 110 is a socket, and the second housing 130 is an insulating end plate.

[0128] Since the connection between the lead wire 200 and the terminal 302 is located inside the sealed cavity, the sealed cavity can effectively prevent external media such as oil and refrigerant from seeping into the connection between the lead wire 200 and the terminal 302. It has a good sealing effect and avoids the situation where the insulation resistance of the motor stator drops sharply due to the seepage of media such as oil and refrigerant into the connection between the lead wire 200 and the terminal 302. This helps to ensure the performance and reliability of the motor.

[0129] Understandably, the cover plate assembly 100 is used in conjunction with the motor's insulating bracket. The cover plate assembly 100 serves to fix and limit the lead wire 200, ensuring the proper fit between the lead wire 200 and the motor connection device. This prevents the lead wire 200 from shifting, thus avoiding disconnection between the lead wire 200 and the wiring portion 302, providing effective structural support for the product's stability and reliability. Furthermore, the first housing 110 and the second housing 130 cooperate to ensure the connection between the lead wire 200 and the wiring portion 302 is located within a sealed cavity. This design prevents external forces from directly acting on the lead wire 200 and the wiring portion 302, providing protection and extending the product's service life.

[0130] Furthermore, the first housing 110 and the second housing 130 are detachably connected, which facilitates the assembly and disassembly of the lead wire 200 relative to the cover assembly 100, resulting in low production costs. This arrangement also facilitates the cleaning and maintenance of the cover assembly 100.

[0131] Specifically, the cover assembly 100 is an insulating cover assembly.

[0132] Example 2:

[0133] like Figures 1 to 8 , Figure 23 As shown, based on Embodiment 1, Embodiment 2 provides a cover plate assembly 100 for a motor, the motor including lead wires 200, and the cover plate assembly 100 including a first housing 110 and a second housing 130.

[0134] The first housing 110 is provided with a first connecting portion 112, and the second housing 130 is detachably connected to the first housing 110. The first housing 110 and the second housing 130 enclose a sealing cavity and a second connecting portion 190.

[0135] Both the first connecting part 112 and the second connecting part 190 are connected to the sealing cavity, and the second connecting part 190 is used to allow the lead wire 200 to extend into the sealing cavity.

[0136] Furthermore, such as Figure 8 , Figure 9 , Figure 10 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, a portion of the first housing 110 protrudes to form a first mounting groove 114; a portion of the second housing 130 protrudes to form a second mounting groove 132; the first mounting groove 114 extends into the second mounting groove 132; the inner wall surface of the second mounting groove 132 and the inner wall surface of the first mounting groove 114 enclose a sealing cavity; the protrusion direction of the first mounting groove 114 is opposite to the protrusion direction of the second mounting groove 132.

[0137] In detail, the first housing 110 has a first mounting groove 114 and the second housing 130 has a second mounting groove 132. When the first housing 110 and the second housing 130 are connected, the first mounting groove 114 of the first housing 110 extends into the second mounting groove 132, so that the inner wall surface of the first mounting groove 114 and the inner wall surface of the second mounting groove 132 form a sealed cavity for accommodating the lead wire 200.

[0138] The protrusion direction of the first mounting groove 114 is opposite to that of the second mounting groove 132. That is, the first mounting groove 114 and the second mounting groove 132 are fastened together. The inner wall surface of the first mounting groove 114 and the inner wall surface of the second mounting groove 132 cooperate to achieve effective protection. Even if media such as oil and refrigerant seep into the cover plate assembly 100, the outer wall surface of the second mounting groove 132 will also block the medium to ensure the sealing effect of the sealing cavity.

[0139] Specifically, the outer wall surface of the first mounting groove 114 abuts against the inner wall surface of the second mounting groove 132 to improve the sealing performance of the sealing cavity.

[0140] Example 3:

[0141] like Figures 1 to 8 , Figure 23 As shown, based on Embodiment 2, Embodiment 3 provides a cover plate assembly 100 for a motor, the motor including lead wires 200, and the cover plate assembly 100 including a first housing 110 and a second housing 130.

[0142] The first housing 110 is provided with a first connecting portion 112, and the second housing 130 is detachably connected to the first housing 110. The first housing 110 and the second housing 130 enclose a sealing cavity and a second connecting portion 190.

[0143] Both the first connecting part 112 and the second connecting part 190 are connected to the sealing cavity, and the second connecting part 190 is used to allow the lead wire 200 to extend into the sealing cavity.

[0144] A portion of the first housing 110 protrudes to form a first mounting groove 114; a portion of the second housing 130 protrudes to form a second mounting groove 132, the first mounting groove 114 extends into the second mounting groove 132, and the inner wall surface of the second mounting groove 132 and the inner wall surface of the first mounting groove 114 enclose a sealing cavity; the protrusion direction of the first mounting groove 114 is opposite to the protrusion direction of the second mounting groove 132.

[0145] Furthermore, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 14 As shown, the first housing 110 includes a mounting plate 116, a first mounting groove 114 located on one side of the mounting plate 116, a portion of the mounting plate 116 protruding from the side of the first mounting groove 114, and the top wall of the second mounting groove 132 abutting against the portion of the mounting plate 116 protruding from the side of the first mounting groove 114.

[0146] In detail, by rationally configuring the mating structure of the first housing 110 and the second housing 130, the first housing 110 includes a mounting plate 116, and the first mounting groove 114 is located on one side of the mounting plate 116. After the first housing 110 and the second housing 130 are assembled, the top wall of the second mounting groove 132 abuts against the portion of the mounting plate 116 that protrudes from the side of the first mounting groove 114. The top wall of the second mounting groove 132 and the mounting plate 116 are connected to achieve a sealing effect. Thus, even if media such as oil or refrigerant seep into the cover plate assembly 100 and the accumulated height of the media is high, the media will be blocked outside the sealing cavity by the abutting top wall of the second mounting groove 132 and the mounting plate 116, resulting in a good sealing effect.

[0147] Specifically, the top wall of the second mounting groove 132 and the portion of the mounting plate 116 protruding from the side of the first mounting groove 114 are in surface contact. This arrangement increases the mating area and mating angle of the first housing 110 and the second housing 130, achieving sealing at multiple angles, which is beneficial to improving the effectiveness and feasibility of sealing the cover assembly 100.

[0148] Specifically, the top wall of the second mounting groove 132 includes any one or a combination of the following: a plane, a curved surface, and a folded surface.

[0149] Example 4:

[0150] like Figures 1 to 8 , Figure 23 As shown, based on Embodiment 3, Embodiment 4 provides a cover plate assembly 100 for a motor, the motor including lead wires 200, and the cover plate assembly 100 including a first housing 110 and a second housing 130.

[0151] The first housing 110 is provided with a first connecting portion 112, and the second housing 130 is detachably connected to the first housing 110. The first housing 110 and the second housing 130 enclose a sealing cavity and a second connecting portion 190.

[0152] Both the first connecting part 112 and the second connecting part 190 are connected to the sealing cavity, and the second connecting part 190 is used to allow the lead wire 200 to extend into the sealing cavity.

[0153] A portion of the first housing 110 protrudes to form a first mounting groove 114; a portion of the second housing 130 protrudes to form a second mounting groove 132, the first mounting groove 114 extends into the second mounting groove 132, and the inner wall surface of the second mounting groove 132 and the inner wall surface of the first mounting groove 114 enclose a sealing cavity; the protrusion direction of the first mounting groove 114 is opposite to the protrusion direction of the second mounting groove 132.

[0154] The first housing 110 includes a mounting plate 116, a first mounting groove 114 located on one side of the mounting plate 116, a portion of the mounting plate 116 protruding from the side of the first mounting groove 114, and the top wall of the second mounting groove 132 abutting against the portion of the mounting plate 116 protruding from the side of the first mounting groove 114.

[0155] Furthermore, such as Figure 9 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, the first housing 110 is provided with a first baffle 118, the first baffle 118 and the first mounting groove 114 are located on the same side of the mounting plate 116, the first baffle 118 is provided with a first recess 120, and the first recess 120 is connected to the first mounting groove 114.

[0156] The second housing 130 is provided with a second baffle 134, and the portion of the second baffle 134 corresponding to the first recess 120 is provided with a second recess 136, which is connected to the second mounting groove 132.

[0157] The first concave portion 120 and the second concave portion 136 have opposite concave directions, and the first concave portion 120 and the second concave portion 136 surround the second communication portion 190 .

[0158] In detail, the first housing 110 is provided with a first baffle 118, and the second housing 130 is provided with a second baffle 134. The first baffle 118 is provided with a first recess 120, and the second baffle 134 is provided with a second recess 136. The recesses of the first recess 120 and the second recess 136 are in opposite directions, and the wall surfaces of both the first recess 120 and the second recess 136 are engaged with the outer peripheral wall of the lead wire 200. That is, the first recess 120 and the second recess 136 cooperate to allow the lead wire 200 to extend into the sealed cavity.

[0159] The first baffle 118 and the second baffle 134 cooperate to achieve a multiple sealing effect, which helps to improve the sealing effect of the cover assembly 100 on the lead wire 200. In addition, the first recess 120 and the second recess 136 have opposite recess directions, that is, the first recess 120 and the second recess 136 cooperate to support and fix the lead wire 200.

[0160] Specifically, the mounting plate 116 forms the bottom wall of the first mounting groove 114. The first mounting groove 114 includes a first wall and a second wall. Both the first wall and the second wall are located on one side of the mounting plate 116 and are connected to the mounting plate 116.

[0161] Furthermore, the first recess 120 and the second recess 136 cooperate to compress the lead wire 200 located in the second connecting portion 190.

[0162] The lead wire 200 includes a conductor 202, a sleeve 204, and a terminal 206. The conductor 202 is electrically connected to the terminal 206. The sleeve 204 is fitted over the outside of the conductor 202 and is located on one side of the terminal 206. The first recess 120 and the second recess 136 cooperate to compress the lead wire 200 located within the connecting portion. The sleeve 204 deforms under pressure, thus the outer wall surface of the sleeve 204 is tightly fitted with the first recess 120 and the second recess 136 to achieve a sealing effect. In other words, the second connecting portion 190 is interference-fitted with the lead wire 200.

[0163] Since the first recess 120 and the second recess 136 are recessed in opposite directions, the lead wire 200 can be squeezed from multiple directions and multiple angles at the same time, so as to effectively prevent media such as oil and refrigerant from seeping into the cover plate assembly 100.

[0164] The second connecting part 190 cooperates with the sealing cavity to achieve a multiple sealing effect, which helps to improve the sealing effect of the cover plate assembly 100 at the connection between the lead wire 200 and the wiring part 302.

[0165] Example 5:

[0166] like Figures 1 to 8 , Figure 23As shown, based on Embodiment 4, Embodiment 5 provides a cover plate assembly 100 for a motor, the motor including lead wires 200, and the cover plate assembly 100 including a first housing 110 and a second housing 130.

[0167] The first housing 110 is provided with a first connecting portion 112, and the second housing 130 is detachably connected to the first housing 110. The first housing 110 and the second housing 130 enclose a sealing cavity and a second connecting portion 190.

[0168] Both the first connecting part 112 and the second connecting part 190 are connected to the sealing cavity, and the second connecting part 190 is used to allow the lead wire 200 to extend into the sealing cavity.

[0169] A portion of the first housing 110 protrudes to form a first mounting groove 114; a portion of the second housing 130 protrudes to form a second mounting groove 132, the first mounting groove 114 extends into the second mounting groove 132, and the inner wall surface of the second mounting groove 132 and the inner wall surface of the first mounting groove 114 enclose a sealing cavity; the protrusion direction of the first mounting groove 114 is opposite to the protrusion direction of the second mounting groove 132.

[0170] The first housing 110 includes a mounting plate 116, a first mounting groove 114 located on one side of the mounting plate 116, a portion of the mounting plate 116 protruding from the side of the first mounting groove 114, and the top wall of the second mounting groove 132 abutting against the portion of the mounting plate 116 protruding from the side of the first mounting groove 114.

[0171] The first housing 110 is provided with a first baffle 118, which is located on the same side of the mounting plate 116 as the first mounting groove 114. The first baffle 118 is provided with a first recess 120, which is connected to the first mounting groove 114.

[0172] The second housing 130 is provided with a second baffle 134, and the portion of the second baffle 134 corresponding to the first recess 120 is provided with a second recess 136, which is connected to the second mounting groove 132.

[0173] The first concave portion 120 and the second concave portion 136 have opposite concave directions, and the first concave portion 120 and the second concave portion 136 surround the second communication portion 190 .

[0174] Furthermore, there are multiple second baffles 134; multiple second baffles 134 are arranged at intervals along the direction from the second baffle 134 to the first baffle 118.

[0175] In detail, there are multiple second baffles 134. By reasonably setting the cooperation structure of multiple second baffles 134, multiple second baffles 134 are arranged at intervals along the direction from the second baffle 134 to the first baffle 118. This arrangement increases the cooperation area between the second connecting part 190 and the lead wire 200, so as to ensure the support and fixing effect of the second connecting part 190 on the lead wire 200.

[0176] In addition, multiple second baffles 134 are arranged at intervals, which is equivalent to defining multiple groove structures. If media such as oil and refrigerant seep into the cover plate assembly 100, they must pass through multiple groove structures one by one. In other words, this setting achieves multiple seals.

[0177] Specifically, the second mounting groove 132 includes a third wall and a fourth wall, which are arranged opposite to each other and spaced apart. The outermost second baffle 134 is connected to both the third wall and the fourth wall. That is, the outermost second baffle 134 constitutes one side wall of the second mounting groove 132, and the remaining second baffles 134 are all located inside the second mounting groove 132.

[0178] Furthermore, there are two first baffles 118, and multiple second baffles 134 are located between the two first baffles 118.

[0179] There are two first baffles 118. One of the two first baffles 118 is located on one side of the multiple second baffles 134, and the other of the two first baffles 118 is located on the other side of the multiple second baffles 134. The two first baffles 118 and the multiple second baffles 134 cooperate with each other. This arrangement is equivalent to defining multiple groove structures. If media such as oil and refrigerant seep into the cover plate assembly 100, they must pass through multiple groove structures one by one. In other words, this arrangement achieves multiple seals.

[0180] Specifically, one of the two first baffles 118 extends into the second mounting groove 132, and the other of the two first baffles 118 is located outside the second mounting groove 132.

[0181] Example 6:

[0182] like Figures 1 to 8 , Figure 23 As shown, based on any of the embodiments in Embodiments 3 to 5, Embodiment 6 provides a cover plate assembly 100 for a motor, the motor including lead wires 200, and the cover plate assembly 100 including a first housing 110 and a second housing 130.

[0183] The first housing 110 is provided with a first connecting portion 112, and the second housing 130 is detachably connected to the first housing 110. The first housing 110 and the second housing 130 enclose a sealing cavity and a second connecting portion 190.

[0184] Both the first connecting part 112 and the second connecting part 190 are connected to the sealing cavity, and the second connecting part 190 is used to allow the lead wire 200 to extend into the sealing cavity.

[0185] A portion of the first housing 110 protrudes to form a first mounting groove 114; a portion of the second housing 130 protrudes to form a second mounting groove 132, the first mounting groove 114 extends into the second mounting groove 132, and the inner wall surface of the second mounting groove 132 and the inner wall surface of the first mounting groove 114 enclose a sealing cavity; the protrusion direction of the first mounting groove 114 is opposite to the protrusion direction of the second mounting groove 132.

[0186] The first housing 110 includes a mounting plate 116, a first mounting groove 114 located on one side of the mounting plate 116, a portion of the mounting plate 116 protruding from the side of the first mounting groove 114, and the top wall of the second mounting groove 132 abutting against the portion of the mounting plate 116 protruding from the side of the first mounting groove 114.

[0187] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the first housing 110 also includes a protrusion 122, which is connected to the mounting plate 116. The protrusion 122 and the first mounting groove 114 are located on opposite sides of the mounting plate 116. The first connecting part 112 is a through hole that penetrates the bottom wall of the protrusion 122 and the first mounting groove 114.

[0188] In detail, the first housing 110 also includes a protrusion 122 located on one side of the mounting plate 116, and a first mounting groove 114 located on the other side of the mounting plate 116. The first connecting portion 112 is a through hole that penetrates the bottom wall of the protrusion 122 and the first mounting groove 114. That is, the first connecting portion 112 extends from the sealing cavity in a direction away from the sealing cavity. In this way, media such as oil and refrigerant outside the cover plate assembly 100 need to pass over the protrusion 122 to enter the first connecting portion 112. This arrangement helps to improve the sealing effect of the cover plate assembly 100.

[0189] The first connecting part 112 is a through hole, which can penetrate the bottom wall of the protrusion 122 and the first mounting groove 114. Therefore, the wiring part 302 of the device that is electrically connected to the motor is inserted into the through hole from top to bottom and enters the sealing cavity to be electrically connected to the lead wire 200 in the sealing cavity.

[0190] Specifically, the lead wire 200 has a mating surface that corresponds to the through hole, so that the wiring part 302 is inserted into the through hole and electrically connected to the mating surface of the lead wire 200.

[0191] Furthermore, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 14 As shown, from the protrusion 122 toward the edge of the first housing 110, the mounting plate 116 includes a first plate 1162 and a second plate 1164; along the direction from the first housing 110 to the second housing 130, the first plate 1162 is located above the second plate 1164; wherein, the protrusion 122 is connected to the first plate 1162.

[0192] The mounting plate 116 includes a first plate 1162 and a second plate 1164. The second plate 1164 is located on one side of the first plate 1162. Along the direction from the first housing 110 to the second housing 130, the first plate 1162 is located above the second plate 1164, and the protrusion 122 is connected to the higher first plate 1162. In this way, media such as oil and refrigerant outside the cover plate assembly 100 need to pass through the first plate 1162 and the protrusion 122 in sequence before entering the first connecting part 112. This arrangement helps to improve the sealing effect of the cover plate assembly 100.

[0193] Furthermore, along the direction from the first housing 110 to the second housing 130, the portion of the bottom wall of the second mounting groove 132 corresponding to the through hole is located above the portion of the bottom wall of the second mounting groove 132 corresponding to the second connecting portion 190.

[0194] By rationally designing the structure of the second mounting groove 132, the bottom wall of the second mounting groove 132 includes a portion corresponding to the through hole and a portion corresponding to the second connecting portion 190. The portion of the bottom wall of the second mounting groove 132 corresponding to the through hole is located above the portion of the bottom wall of the second mounting groove 132 corresponding to the second connecting portion 190. This means the portion of the lead wire 200 used for electrical connection with the wiring portion 302 is positioned higher. Thus, even if oil or refrigerant seeps into the cover plate assembly 100, it will only flow to the connection point between the lead wire 200 and the wiring portion 302 when the accumulated height of the oil or refrigerant reaches a certain value. This design effectively prevents a sharp drop in the insulation resistance of the motor stator, thus ensuring the performance and reliability of the motor.

[0195] Example 7:

[0196] like Figures 1 to 8 , Figure 23As shown, based on any of the embodiments in Embodiments 2 to 6, Embodiment 7 provides a cover plate assembly 100 for a motor, the motor including lead wires 200, and the cover plate assembly 100 including a first housing 110 and a second housing 130.

[0197] The first housing 110 is provided with a first connecting portion 112, and the second housing 130 is detachably connected to the first housing 110. The first housing 110 and the second housing 130 enclose a sealing cavity and a second connecting portion 190.

[0198] Both the first connecting part 112 and the second connecting part 190 are connected to the sealing cavity, and the second connecting part 190 is used to allow the lead wire 200 to extend into the sealing cavity.

[0199] A portion of the first housing 110 protrudes to form a first mounting groove 114; a portion of the second housing 130 protrudes to form a second mounting groove 132, the first mounting groove 114 extends into the second mounting groove 132, and the inner wall surface of the second mounting groove 132 and the inner wall surface of the first mounting groove 114 enclose a sealing cavity; the protrusion direction of the first mounting groove 114 is opposite to the protrusion direction of the second mounting groove 132.

[0200] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the cover plate assembly 100 also includes a first connecting part 140 and a second connecting part 150. The first connecting part 140 is disposed in the first housing 110, and the second connecting part 150 is disposed in the second housing 130. The first housing 110 and the second housing 130 are detachably connected through the first connecting part 140 and the second connecting part 150.

[0201] In detail, the cover plate assembly 100 further includes a first connecting portion 140 and a second connecting portion 150. The first connecting portion 140 is disposed on the first housing 110, and the second connecting portion 150 is disposed on the second housing 130. The first connecting portion 140 and the second connecting portion 150 are detachably connected, thereby achieving the purpose of detachably connecting the first housing 110 and the second housing 130. This arrangement ensures the mating dimensions of the first housing 110 and the second housing 130, providing effective structural support for the effectiveness and feasibility of forming a sealing cavity between the first housing 110 and the second housing 130.

[0202] It is understood that the first housing 110 and the second housing 130 are detachably connected via the first connecting portion 140 and the second connecting portion 150 to create a sealed cavity between the first housing 110 and the second housing 130. When it is necessary to disassemble the cover plate assembly 100, external force can be applied to the first housing 110 and / or the second housing 130 to overcome the bonding force between the first housing 110 and the second housing 130, thereby achieving the separation of the first housing 110 and the second housing 130. This structural design provides assembly reliability, facilitates installation and subsequent disassembly and maintenance, and also facilitates the adjustment and calibration of the first housing 110 relative to the second housing 130 during the assembly process.

[0203] In this embodiment, one of the first connecting part 140 and the second connecting part 150 is a snap fastener and the other is a latching part, and the snap fastener and the latching part engage with each other.

[0204] Specifically, another connection method is defined for the first housing 110 and the second housing 130: the first housing 110 and the second housing 130 are snap-fit ​​connected.

At least one second connecting portion 150 is provided on the outer wall of each second mounting groove 132, and each second connecting portion 150 is detachably connected to one first connecting portion 140. That is, there are N sealing cavities, and consequently, there are N mating connections between the first housing 110 and the second housing 130.

[0213] Example 8:

The cover plate assembly 100 serves to fix and limit the lead wire 200, ensuring the proper fit between the lead wire 200 and the motor connection device. This prevents the lead wire 200 from shifting, thus avoiding disconnection between the lead wire 200 and the wiring portion 302, providing effective structural support for the product's stability and reliability. Furthermore, the first housing 110 and the second housing 130 cooperate to ensure the connection between the lead wire 200 and the wiring portion 302 is located within a sealed cavity.
