[0037] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] The present invention proposes a compressor that aims to reduce the impact noise between the pump body and the housing when a collision occurs between the pump body and the housing inside the compressor, thereby improving the performance of the compressor while ensuring the comfort of the application environment. It can be understood that the compressor proposed by the present invention can be applied to any application where shaking and vibration may occur, such as household refrigerators, commercial refrigerators or car refrigerators, etc., and is not limited to a specific application. The following description takes the application of the compressor in a car refrigerator as an example.

[0042] In the embodiment of the present invention, Figures 1 to 5 As shown, the compressor includes a shell 1 and a pump body (not marked in the figure).

[0043] The pump body is arranged in the shell 1, and the pump body includes a stator component. The stator component includes a stator core 200 and an insulating frame 300 installed on the stator core 200. The insulating frame 300 is provided with a buffer component 400. The buffer component 400 is located between the stator component and the shell 1, and the buffer component 400 is made of non-metallic material.

[0044] It can be understood that the pump body includes a crankshaft, a crankcase and a motor. The motor includes a stator component and a rotor component that cooperates with the stator component. The rotor component is fixedly matched with the crankshaft so that when the rotor component rotates, it can drive the crankshaft to rotate, thereby achieving the purpose of compressing the refrigerant medium in the crankcase. In actual application, the rotor component is built into the middle of the stator component. The stator component and the crankcase are fixedly assembled to form a pump body of an integral structure, which is installed in the inner cavity of the housing 1. In this embodiment, the stator component includes a stator core 200 and an insulating frame 300. The insulating frame 300 is installed at the end of the stator core 200 to support and fix the stator core 200, and at the same time to insulate the stator core 200 from the coil winding. Based on this, it can be seen that the insulating frame 300 is an insulating material. By arranging a buffer component 400 on the insulating skeleton 300, the buffer component 400 is protruded toward the shell 1. It can be understood that the buffer component 400 is protruded toward the shell 1 relative to the pump body of the overall structure, so that when the compressor is subjected to a large shake or bump, and relative shaking occurs between the pump body and the shell 1, the buffer component 400 can contact the shell 1 to avoid direct contact between the pump body and the shell 1, thereby playing a buffering role for the pump body and the shell 1. At the same time, the buffer component 400 is made of non-metallic material, and the collision between the buffer component 400 and the shell 1 is a non-metal-metal collision, avoiding the generation of metal collision sound, thereby achieving the purpose of reducing the impact noise of the compressor, making the compressor sound low, and meeting the NVH (Noise, Vibration, Harshness) requirements of the whole machine.

[0045] In actual application, the shape and structure of the buffer component 400 can be determined according to actual conditions. For example, it can be a block structure, a plate structure, a strip structure or other special-shaped structures. As long as it is ensured that when the pump body shakes relative to the shell 1, the buffer component 400 can avoid direct contact between the pump body and the shell 1 to reduce the metal impact noise, its specific shape and structure do not need to be limited here.

[0046] The position distribution of the buffer assembly 400 can be determined according to actual conditions. For example, it can be set on the side or top of the stator component. When it is located on the side of the stator component, since the shell 1 is wrapped around the outside of the stator component, the buffer assembly 4 can be distributed around the periphery of the stator component at intervals. Then, when the compressor shakes in multiple directions, the buffer assembly 4 can play a limiting and buffering role, so that the pump body will not directly contact and collide with the shell 1 in multiple directions, thereby reducing the noise of the compressor. When the buffer assembly 400 is located at the top of the stator component, this method is suitable for when the compressor is bumped and the pump body may move upward. At this time, the buffer assembly 400 on the top can limit the pump body to prevent the pump body from directly colliding with the shell 1.

[0047] Based on the above distribution method, in order to achieve better buffering and anti-collision effect of the buffer component 400, the buffer component 400 can be set around the stator component, and the insulating frame 300 is set at the end of the stator core 200. The buffer component 400 can be set around the outer periphery of the insulating frame 300, and it can be protruded toward the peripheral wall of the shell 1, or protruded toward the top wall of the shell 1, so as to protect the pump body in multiple directions and prevent the pump body from colliding with the shell 1.

[0048] It should be noted that, in actual use, the pump body is installed inside the housing 1, with a certain gap between the two to prevent collision and friction during normal operation of the compressor. Based on this, in order to avoid wear during normal operation, a gap is set between the buffer assembly 400 and the housing 1 to prevent internal components of the compressor from colliding and wearing when the compressor is not shaken or bumped. This ensures that the buffer assembly 400 only contacts the housing 1 when it shakes or bumps, thereby preventing the pump body from hitting the housing 1 and reducing noise.

[0049] It is understandable that the material selection of the buffer component 400 can be the same as or different from the material of the insulating frame 300. The buffer component 400 plays the role of limiting and protecting the pump body, while taking into account the impact effect with the shell 1, so the buffer component 400 can be made of a plastic material with a certain strength, such as HIPS (high impact polystyrene), PBT (polybutylene terephthalate), GPPS (general-purpose polystyrene) or PET (polyethylene terephthalate). The insulating frame 300 plays the role of supporting insulation in the stator component 2, so the insulating frame 300 can also be made of a plastic material with a certain strength, such as HIPS (high impact polystyrene), PBT (polybutylene terephthalate), GPPS (general-purpose polystyrene) or PET (polyethylene terephthalate). The connection between the buffer component 400 and the insulating frame 300 can be one-piece molding fixation or adhesive fixation.

[0050] In the compressor of the technical solution of the present invention, the pump body is arranged in the shell 1, and the pump body includes a stator component, and the stator component includes a stator core 200 and an insulating frame 300 installed on the stator core 200. The buffer component 400 is arranged through the insulating frame 300, so that when the compressor is shaken or bumped and the pump body shakes relative to the shell 1, the buffer component 400 can contact the shell 1 and avoid direct contact between the pump body and the shell 1, thereby playing a buffering role for the pump body and the shell 1. At the same time, the buffer component 400 is made of non-metallic material, so the collision between the buffer component 400 and the shell 1 is a non-metal-metal collision, avoiding the generation of metal collision sound, thereby achieving the purpose of reducing the impact noise of the compressor, making the compressor sound low, and meeting the NVH (Noise, Vibration, Harshness) requirements of the whole machine.

[0051] In order to improve assembly efficiency, refer to Figures 1 to 5 In one embodiment of the present invention, the buffer assembly 400 and the insulating frame 300 are an integrally formed structure.

[0052] In this embodiment, by integrally forming the insulating frame 300 and the buffer assembly 400, the insulating frame 300 and the buffer assembly 400 can be manufactured using only injection molding, without the need to set up multiple different molding molds, thereby reducing the assembly process and lowering the process cost.

[0053] It is understandable that the insulating frame 300 and the buffer assembly 400 can be integrally formed of the same material or of different materials. To further improve molding efficiency, in this embodiment, the insulating frame 300 and the buffer assembly 400 are integrally injection molded using PBT material. This ensures the strength and insulation performance of the insulating frame 300 while also ensuring the impact resistance and non-metallic properties of the buffer assembly 400. In actual application, the insulating frame 300 and the buffer assembly 400 can be equivalent to an integral structure, which can not only provide support and insulation for the stator core 200, but also provide anti-collision and buffering effects for the pump body.

[0054] In one embodiment of the present invention, referring to Figures 1 to 5 The insulating frame 300 includes a bracket 310 installed at the end of the stator core 200, and the bracket 310 is configured as a ring structure;

[0055] The buffer assembly 400 includes at least two first position-limiting members 410 . The at least two first position-limiting members 410 are spaced apart from each other on the outer wall of the bracket 310 .

[0056] As will be understood, the motor within the pump body consists of a stator component 2 and a rotor component. A mounting hole for accommodating the rotor component is provided within the stator core 200. Furthermore, the bracket 310 is annular and mounted at the end of the stator core 200 to provide sufficient rotational space for the rotor component. The buffer assembly 400 includes at least two first stoppers 410, which are spaced apart from each other on the outer circumferential wall of the bracket 310 to provide collision protection for the pump body in different directions.

[0057] During actual application, the at least two first limit members 410 are evenly spaced around the central axis of the bracket 310, so that the first limit members 410 are provided at different positions of the periphery of the pump body, so that when the pump body shakes in different directions, there will be a first limit member 410 blocking between the pump body and the shell 1 to prevent the pump body from colliding with the shell 1, thereby achieving the purpose of protecting the pump body in all directions.

[0058] Optionally, the number of the first limit members 410 can be determined according to actual conditions, such as two, three, four, etc. In this embodiment, considering the layout of the internal structure of the compressor and factors such as cost, two first limit members 410 are set on the outer peripheral wall of the bracket 310. The two first limit members 410 can be symmetrically distributed to limit the shaking of the pump body in the left and right directions. At the same time, different limiting surfaces can also be set on the first limit member 410 to limit the shaking of the pump body in different directions.

[0059] In one embodiment of the present invention, referring to Figures 1 to 5The first limiting member 410 includes a first connecting plate 411 and a first buffer block 412; the first connecting plate 411 is connected to the bracket 310 and extends outward from the bracket 310 along the radial direction of the bracket 310; the plate surface of the first connecting plate 411 abuts against the end face of the stator core 200; the first buffer block 412 is connected to the first connecting plate 411 and is located between the stator core 200 and the housing 1.

[0060] It can be understood that, based on the aforementioned embodiment in which the bracket 310 is an annular structure, the first connecting plate 411 extends radially outward from the bracket 310, and the plate surface of the first connecting plate 411 abuts against the end face of the stator core 200. The first connecting plate 411 and the bracket 310 form a limiting support for the stator core 200 to further improve the stability of the connection structure of the buffer assembly 400, the insulating frame 300 and the stator core 200. At the same time, the first connecting plate 411 extends along the end face of the stator core 200, and the overall structural layout is more compact.

[0061] A first buffer block 412 is provided at the end of the first connecting plate 411 facing away from the bracket 310. The first buffer block 412 is located between the stator core 200 and the housing 1 to provide a barrier and prevent collision between the stator core 200 and the housing 1. It is understood that the first buffer block 412 can have either a contact fit or a clearance fit with the stator core 200. When in contact fit, the first buffer block 412 can both secure the stator core 200 and provide a buffer. When in clearance fit, an air-insulated area is formed between the first buffer block 412 and the stator core 200, providing a better buffer and collision prevention effect.

[0062] In one embodiment of the present invention, referring to Figures 1 to 5 A first abutting surface 413 is formed on one side of the first buffer block 412, which abuts against the outer wall of the stator core 200. A plurality of limiting surfaces (401 / 402 / 403) with different directions are formed on the side of the first buffer block 412 facing away from the stator core 200. The plurality of limiting surfaces (401 / 402 / 403) are enclosed to form a limiting groove 412d.

[0063] In this embodiment, a first abutting surface 413 is formed on the surface of one end of the first buffer block 412 connected to the first connecting plate 411, which abuts against the outer wall of the stator core 200. The first abutting surface 413 is connected to the plate surface of the first connecting plate 411 to form a space for clamping and fitting the stator core 200. The first connecting plate 411 abuts against the end face of the stator core 200, and the first buffer block 412 abuts against the outer wall of the stator core 200, further improving the assembly strength of the first limit member 410, the insulating frame 300 and the stator core 200.

[0064] At the same time, the first buffer block 412 forms a plurality of limiting surfaces (401 / 402 / 403) in different directions on the side facing away from the stator core 200, and the plurality of limiting surfaces enclose a limiting groove 412d. It can be understood that in actual application, a corresponding shell limiting member can be provided on the shell 1, so as to utilize the cooperation between the shell limiting member and the limiting groove 412d to realize the limiting cooperation between the plurality of limiting surfaces and the shell limiting member, thereby realizing the limiting and anti-collision function of the pump body in different directions.

[0065] In actual application, the relationship between the multiple limiting surfaces can be determined according to actual conditions. For example, they can intersect with each other or with each other, as long as the limiting directions of different limiting surfaces are different.

[0066] In one embodiment, the plurality of limiting surfaces are configured as a first limiting surface 401 , a second limiting surface 402 , and a third limiting surface 403 that are perpendicular to each other.

[0067] In this embodiment, the first buffer block 412 is formed with a first limiting surface 401, a second limiting surface 402 and a third limiting surface 403 that are perpendicular to each other on the side away from the first abutting surface 413. The three limiting surfaces can respectively limit the shaking and collision prevention of the pump body in three directions, such as limiting the forward, rightward or upward movement of the pump body. Of course, when the setting position of the first buffer block 412 changes, the limiting direction of the three limiting surfaces will also change. At the same time, based on the aforementioned embodiment in which the buffer assembly 400 includes at least two first limiting members 410, symmetrical first limiting members 410 can be respectively set on the opposite sides of the bracket 310, and then the first buffer blocks 412 with three limiting surfaces are respectively provided on the opposite sides of the stator core 200, so that the pump body can be limited in multiple directions such as forward, backward, left, right or upward.

[0068] In one embodiment of the present invention, referring to Figures 1 to 5 The first buffer block 412 includes a first limiting plate 412a, a second limiting plate 412b and a third limiting plate 412c which are vertically connected to each other;

[0069] The first limiting plate 412a is connected to the first connecting plate 411, and the first abutting surface 412 and the first limiting surface 401 are respectively provided on two opposite surfaces of the first limiting plate 412a;

[0070] The second limiting plate 412b is connected to the first connecting plate 411 and the first limiting plate 412a. The second limiting plate 412b extends from the first limiting plate 412a in a direction away from the bracket 310. The second limiting surface 402 is provided on the second limiting plate 412b.

[0071] The third limiting plate 412 c is arranged parallel to the first connecting plate 411 and extends from the first limiting plate 412 a in a direction away from the bracket 310 . The third limiting surface 403 is provided on the third limiting plate 412 c .

[0072] It can be understood that the first limiting plate 412a, the second limiting plate 412b and the third limiting plate 412c are vertically connected to each other, the first limiting surface 401 is set on the first limiting plate 412a, the second limiting surface 402 is set on the second limiting plate 412b, and the third limiting surface 403 is set on the third limiting plate 412c. The first limiting plate 412a, the second limiting plate 412b and the third limiting plate 412c are enclosed to form a limiting groove 412d.

[0073] The first limiting plate 412a has a first abutting surface 413 and a first limiting surface 401 on opposite sides thereof, and the first limiting plate 412a is vertically connected to the first connecting plate 411. The first limiting plate 412a extends downwardly from the first connecting plate 411 along the axial direction of the stator core 200, so that the first limiting plate 412a and the outer wall of the stator core 200 have sufficient abutting area, thereby better limiting the installation of the stator core 200. At the same time, the side of the first limiting plate 412a facing away from the stator core 200 is the first limiting surface 401. One surface of the first limiting plate 412a abuts against the stator core 200, while the other side is used to limit collision with the housing 1 or a limiting member of the housing, thereby ensuring that the first limiting plate 412a has sufficient impact resistance and improving structural reliability.

[0074] The second limiting plate 412b and the third limiting plate 412c are vertically connected and are both connected to the first limiting plate 412a, wherein the second limiting plate 412b extends from the first limiting plate 412a in a direction away from the bracket 310, and the third limiting plate 412c extends from the first limiting plate 412a in a direction away from the bracket 310, and the third limiting plate 412c is arranged parallel to the first connecting plate 411. The limiting groove 412d formed by the first limiting plate 412a, the second limiting plate 412b and the third limiting plate 412c is a three-dimensional right-angle groove, which can be used to install the shell limiting part on the shell, and at the same time can be opposite to the shell limiting part gap from three different limiting surfaces, so that when the compressor is shaken or bumped, the limiting surface will be against the shell limiting part for limitation.

[0075] In this embodiment, by setting a first limiting plate 412a, a second limiting plate 412b and a third limiting plate 412c that are perpendicular to each other, the structural strength of the first buffer block 412 is further increased compared to a single plate structure or block structure, ensuring better anti-impact effect.

[0076] In order to further improve the anti-collision effect between the pump body and the housing 1, refer to Figures 1 to 5 In one embodiment of the present invention, the buffer assembly 400 further includes a second limiting member 420 , which is disposed on the outer peripheral wall of the bracket 310 ; the second limiting member 420 is spaced apart from the first limiting member 410 .

[0077] It can be understood that the buffer assembly 400 also includes a second limit member 420, which has a different limiting direction from the first limit member 410. The second limit member 420 is arranged on the outer wall of the bracket 310 and is spaced apart from the first limit member 410, which is equivalent to compensating for the limiting directions of at least two first limit members 410, so that on the basis of the limiting direction of the pump body by the first limit member 410, the limiting direction of the pump body is further increased, thereby achieving the purpose of further improving the limiting anti-collision.

[0078] In actual application, at least two first limiting members 410 and second limiting members 420 are evenly distributed on the outer wall of the annular bracket 310. Optionally, the first limiting member 410 limits the pump body forward, left, right and upward, and the second limiting member 420 limits the pump body upward and backward.

[0079] In one embodiment of the present invention, the second limiting member 420 includes a second connecting plate 421 and a second buffer block 422. One end of the second connecting plate 421 is connected to the bracket 310, and the other end extends outward in the radial direction of the bracket 310; the plate surface of the second connecting plate 421 abuts against the end surface of the stator core 200; the second buffer block 422 is connected to the second connecting plate 421 and is located between the stator core 200 and the housing 310.

[0080] It can be understood that, based on the aforementioned embodiment in which the bracket 310 is an annular structure, the second connecting plate 421 extends radially outward from the bracket 310, and the plate surface of the second connecting plate 421 abuts against the end face of the stator core 200. The second connecting plate 421 and the bracket 310 form a limiting support for the stator core 200 to further improve the stability of the connection structure of the buffer assembly 400, the insulating frame 300 and the stator core 200. At the same time, the second connecting plate 421 extends along the end face of the stator core 200, and the overall structural layout is more compact.

[0081] A second buffer block 422 is provided at the end of the second connecting plate 421 facing away from the bracket 310. The second buffer block 422 is located between the stator core 200 and the housing 1 to provide a barrier and prevent collision between the stator core 200 and the housing 1. It is understood that the second buffer block 422 can have either a contact fit or a clearance fit with the stator core 200. When in contact fit, the second buffer block 422 can both secure the stator core 200 and provide a buffer. When in clearance fit, an air-insulated area is formed between the second buffer block 422 and the stator core 200, providing a better buffer and collision prevention effect.

[0082] In one embodiment of the present invention, referring to Figures 1 to 5 A second abutting surface 423 abutting against the outer wall of the stator core 200 is formed on one side of the second buffer block 422, and a fourth limiting surface 404, a fifth limiting surface 405 and a sixth limiting surface 406 perpendicular to each other are formed on the side of the second buffer block 422 away from the stator core 200.

[0083] In this embodiment, the surface of one end of the second buffer block 422 connected to the second connecting plate 421 is formed with a second abutting surface 423 that abuts against the outer wall of the stator core 200. The second abutting surface 423 is connected to the plate surface of the second connecting plate 421 to form a space for clamping and fitting the stator core 200, so that the end face of the stator core 200 is abutted and fitted by the second connecting plate 421, and the second buffer block 422 is abutted and fitted against the outer wall of the stator core 200, thereby further improving the assembly strength of the second limit member 420, the insulating frame 300 and the stator core 200.

[0084] At the same time, the second buffer block 422 is formed with a fourth limiting surface 404, a fifth limiting surface 405, and a sixth limiting surface 406, which are perpendicular to each other, on the side facing away from the stator core 200. These three limiting surfaces can respectively limit the pump body from shaking in multiple directions and prevent collisions, such as limiting the pump body from moving backward, leftward, forward, or upward. Of course, when the setting position of the second buffer block 422 changes, the limiting directions of the three limiting surfaces will also change.

[0085] On the basis that the buffer assembly 400 of the aforementioned embodiment includes at least two first limiting members 410, symmetrical first limiting members 410 can be respectively arranged on the opposite sides of the bracket 310, and a second limiting member 420 can be arranged in the middle of the two first limiting members 410. The first buffer block 412 of the first limiting member 410 is formed with a first limiting surface 401, a second limiting surface 402 and a third limiting surface 403, and the second buffer block 422 of the second limiting member 420 is formed with a fourth limiting surface 404, a fifth limiting surface 405 and a sixth limiting surface 406. The pump body can be limited in multiple directions such as forward, backward, left, right or upward through multiple different limiting surfaces.

[0086] In one embodiment of the present invention, referring to Figures 1 to 5 The second buffer block 422 includes a fourth limiting block 422a and a fifth limiting block 422b; the fourth limiting block 422a is provided on the second connecting plate 421 and extends along the axial direction of the bracket 310 in a direction away from the stator core 200; the fourth limiting surface 404 and the fifth limiting surface 405 are both provided on the fourth limiting block 422a, and the fourth limiting surface 404 and the second abutting surface 423 are respectively provided on two opposite surfaces of the fourth limiting block 422a;

[0087] The fifth limiting block 422b is provided on the second connecting plate 421 and forms a stepped structure with the fourth limiting block 422a; the sixth limiting surface 406 is provided on the top of the fifth limiting block 422b.

[0088] It can be understood that the fourth limit block 422a and the fifth limit block 422b form a stepped structure, the fourth limit block 422a is higher than the fifth limit block 422b, the fourth limit surface 404 is provided on the side of the fourth limit block 422a facing away from the stator core 200, the fifth limit surface 405 is provided on the side where the fourth limit block 422a and the fifth limit block 422b are connected, and the sixth limit surface 406 is provided on the top of the fifth limit block 422b. The fourth limit surface 404, the fifth limit surface 405 and the sixth limit surface 406 correspond to the limit of the pump body in the backward, left (right) and upward directions respectively.

[0089] The fourth limiting block 422a has two opposing sides, namely the second abutting surface 423 and the fourth limiting surface 404. The fourth limiting block 422a is perpendicularly connected to the second connecting plate 421. The fourth limiting block 422a extends from the second connecting plate 421 along the axial direction of the stator core 200, so that the fourth limiting block 422a has a sufficient abutting area with the outer wall of the stator core 200, thereby better limiting the installation of the stator core 200. At the same time, the side of the fourth limiting block 422a facing away from the stator core 200 is the fourth limiting surface 404. One plate surface of the fourth limiting block 422a abuts against the stator core 200, while the other side is used to limit collision with the housing 1 or a limiting member of the housing. This ensures that the fourth limiting block 422a has sufficient impact resistance and improves structural reliability.

[0090] The fifth limiting block 422b extends upward from the second connecting plate 421, and its top surface forms a sixth limiting surface 406 for limiting collision with the shell or the limiting member of the shell to limit the upward movement of the pump body and prevent the pump body from colliding upward with the shell.

[0091] In this embodiment, by providing the fourth limiting block 422a and the fifth limiting block 422b in a stepped shape, the structural strength of the second buffer block 422 is further increased compared to a single plate structure or block structure, thereby ensuring a better anti-impact effect.

[0092] In order to further improve the anti-collision effect between the pump body and the shell, refer to Figures 1 to 5 In one embodiment of the present invention, the shell 1 is provided with a first shell limiter 110 at a position corresponding to the first buffer block 412. The first shell limiter 110 is arranged in the limit groove 412d and is gap-removed from the plurality of limit surfaces (401 / 402 / 403).

[0093] In this embodiment, the shell 1 is provided with at least two first shell limit members 110, and one first shell limit member 110 corresponds to one first buffer block 412. The first shell limit member 110 is protruded from the inner wall of the shell 1 to cooperate with the first buffer block 412 protruding from the pump body. Through the joint action of the first shell limit member 110 and the first buffer block 412, the anti-collision effect between the pump body and the shell 1 is guaranteed.

[0094] It can be understood that one end of the first shell limiter 110 is fixedly connected to the shell 1, and the other end extends into the limit groove 412d of the first buffer block 412, and is arranged relative to the gaps of multiple limit surfaces (401 / 402 / 403), so that when the compressor is in normal operation, the first shell limiter 110 does not contact the first buffer block 412, avoiding contact wear. When the compressor is shaken or bumped, and the pump body shakes relative to the shell, under the shaking of the pump body, the limit surface (401 / 402 / 403) in the first buffer block 412 and the first shell limiter 110 are pressed against each other to achieve an anti-collision buffering effect.

[0095] In actual application, when the first limiting members 410 are respectively provided on the left and right sides of the pump body, the first shell limiting members 110 are correspondingly provided on the opposite sides of the shell 1. At this time, the first limiting surfaces 401 of the first buffer blocks 412 of the first limiting members 410 on the left and right sides respectively abut against the first shell limiting member 110 to the left or right to limit the left or right movement of the pump body, the second limiting surface 402 abuts against the first shell limiting member 110 forward to limit the forward movement of the pump body, and the third limiting surface 403 abuts against the first shell limiting member 110 upward to limit the upward movement of the pump body. In this way, the shaking and impact of the pump body in the forward, left, right and upward directions is achieved.

[0096] In order to further improve the anti-collision effect between the pump body and the shell, refer to Figures 1 to 5In one embodiment of the present invention, the shell 1 is provided with a second shell limiter 120 corresponding to the second buffer block 422, and the second shell limiter 120 is gap-removed from the fourth limiter surface 404, the fifth limiter surface 405 and the sixth limiter surface 406.

[0097] In this embodiment, the second shell limiter 120 of the shell 1 protrudes from the inner wall of the shell 1 to cooperate with the second buffer block 422 protruding from the pump body. Through the joint action of the second shell limiter 120 and the second buffer block 422, the anti-collision effect between the pump body and the shell 1 is ensured.

[0098] It can be understood that the second housing limiter 120 and the second buffer block 422 limit the pump body from rocking backward, upward, left, and right. The second buffer block 422 includes a fourth limiter 422a and a fifth limiter 422b in a stepped shape. The second housing limiter 120 includes a fixing member 121 fixedly connected to the housing 1 and a supporting member 122 perpendicularly connected to the fixing member 121. The fixing member 121 protrudes from the housing 1 toward the pump body to cooperate with the fifth limiting surface 405 and the sixth limiting surface 406 to limit the pump body's movement to the left, right, and upward. The supporting member 122 extends perpendicularly from the fixing member 121 to cooperate with the fourth limiting surface 404 to limit the pump body's movement backward. In this way, the pump body is restricted from rocking backward, upward, left, and right.

[0099] It should be noted that when the compressor is operating normally, the second shell limit member 120 does not contact the second buffer block 422 to avoid contact wear. When the compressor is shaken or bumped and the pump body shakes relative to the shell, under the shaking of the pump body, the fourth limit surface 404, the fifth limit surface 405 and the sixth limit surface 406 in the second buffer block 422 are pressed against the second shell limit member 120 to achieve an anti-collision buffering effect.

[0100] In actual application, the shell 1 can be set as an upper shell and a lower shell, the first shell limiter 110 is set in the lower shell, and the second shell limiter 120 is set in the upper shell. During installation, the stator component is installed in the lower shell so that the first limiter 410 cooperates with the first shell limiter 110 in the lower shell, and then the upper shell is covered so that the second shell limiter 120 cooperates with the second limiter 420, and the upper shell and the lower shell are fixed and installed by welding.

[0101] In one embodiment of the present invention, referring to Figures 1 to 5 The stator core 200 is provided with a plurality of core slots; the insulating frame 300 further includes a plurality of slot insulators 320 provided on the inner side of the bracket 310, and one slot insulator 320 is correspondingly inserted into one core slot.

[0102] In this embodiment, slot insulators 320 are inserted into the corresponding core slots, isolating the winding coils from the stator core 200 and providing insulation between them, preventing short circuits or electric shocks between the winding coils and the stator core 200. In conjunction with the aforementioned embodiment, the buffer assembly 400 is provided on the insulating frame 300, enabling the insulating frame 300 to not only support the stator core 200 but also provide insulation through the slot insulators 320 and, through the buffer assembly 400, provide impact protection.

[0103] In one embodiment of the present invention, referring to Figures 1 to 5 An annular wiring groove 311 is formed on the bracket 310, and the bracket 310 is provided with a plurality of wire blocking portions 312 on the inner side of the annular wiring groove 311. The plurality of wire blocking portions 312 are arranged at intervals around the central axis of the bracket 310; the wire blocking portion 312 is provided with a protrusion 312a on the side facing the annular wiring groove 311.

[0104] As can be understood, after the winding coil is wound, it needs to be led out of the stator component for external connection. Based on this, an annular wiring groove 311 is formed on the bracket 310 to be used for leading out the lead wires of the winding coil. A plurality of wire blocking portions 312 are provided inside the annular wiring groove 311 to play a role in limiting the lead wires.

[0105] In order to better limit the position of the wire body, in one embodiment of the present invention, a protrusion 312a is provided on the side of the wire blocking portion 312 facing the annular wire routing groove 311. Optionally, the protrusion 312a is a triangular structure to protect the winding routing.

[0106] The present invention also proposes a car refrigerator, which includes a compressor. The specific structure of the compressor refers to the above embodiment. Since this car refrigerator adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
