In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the scope of the present utility model is not limited to the specific embodiments disclosed below.

A compressor 100, an air conditioner, and a vehicle provided according to some embodiments of the present utility model are described below with reference to fig. 1 to 12.

In one embodiment according to the present utility model, as shown in fig. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12, a compressor 100 is proposed, the compressor 100 comprising: a housing 110; a compression assembly 120 coupled to the housing 110; a driving part 130 provided in the housing 110 and connected to the compression assembly 120; an electric control part 140 electrically connected to the driving part 130; the cover plate 150 is connected with the shell 110 and forms a mounting cavity 170 with the shell 110 in a surrounding manner, and the electric control part 140 is arranged in the mounting cavity 170; the weight 160 is provided on the cover plate 150.

The compressor 100 provided in the embodiment of the present utility model includes a casing 110, a compression assembly 120, a driving portion 130, an electric control portion 140, a cover plate 150, and a counterweight 160, specifically, the compression assembly 120 is connected to the casing 110, it can be understood that the compression assembly 120 includes a movable disc 121 and a static disc 122, the movable disc 121 and the static disc 122 enclose a compression chamber 123, the driving portion 130 is connected to the compression assembly 120, and the driving portion 130 is connected to the movable disc 121. Specifically, under the control of the electronic control unit 140, the driving unit 130 drives the movable disk 121 to rotate relative to the stationary disk 122, so as to compress the gas in the compression chamber 123, and the compressed high-pressure gas is discharged through the gas outlet 111 on the housing 110.

The cover plate 150 and the housing 110 enclose a mounting cavity 170, and the electric control part 140 is located in the mounting cavity 170, so that the electric control part 140 can be prevented from being corroded due to exposure to the external environment, the service life of the electric control part 140 is prolonged, and stable operation of the compressor 100 is ensured.

It can be appreciated that vibration, that is, vibration noise is generated during the operation of the compressor 100, and the vibration and noise easily excite the resonance noise of the cover plate 150, resulting in a larger operation noise of the compressor 100, so that the air conditioner with the compressor 100 and the vehicle with the air conditioner have larger noise during the driving process, and the use experience of the user is affected.

Through set up the counterweight 160 on apron 150 to adjust the weight distribution on the apron 150, and then adjust the natural frequency of apron 150, reduce the resonance frequency of apron 150 promptly, the transmission of inside vibration noise to casing 110 surface when reducing compressor 100 operation, improve noise radiation, the whole noise when reducing compressor 100 operation, and then reduce the complete machine noise of the air conditioner that has this compressor 100, and reduce the noise of the car that has this air conditioner in the driving process, promote user's use experience.

In practice, the weight 160 may be disposed on a side of the cover plate 150 adjacent to the housing 110, that is, the weight 160 is located in the mounting cavity 170. In addition, the weight 160 may be disposed on a side of the cover plate 150 facing away from the housing 110, i.e., the weight 160 is located outside the installation cavity 170, so as to avoid occupying space of the installation cavity 170. In addition, the weight 160 may include a plurality of weight portions 161, at least one weight portion 161 is disposed on a side of the cover 150 near the housing 110, and at least one weight portion 161 is disposed on a side of the cover 150 facing away from the housing 110. The setting can be specifically performed according to actual needs.

In addition, the weight 160 and the cover plate 150 are integrally formed, and it can be understood that the integral structure has good mechanical properties, so that the connection strength between the weight 160 and the cover plate 150 can be improved, and the weight 160 is prevented from falling off from the cover plate 150. In addition, since the weight 160 is integrally formed with the cover 150, that is, there is no gap between the weight 160 and the cover 150, noise generated due to the relative movement between the weight 160 and the cover 150 can be prevented. Moreover, the integrated structure also facilitates mass production of the cover plate 150, so that the production efficiency of the cover plate 150 can be improved and the production cost of the compressor 100 can be reduced.

Further, the weight 160 is disposed away from the outer edge of the cover plate 150, based on the above embodiment.

In this embodiment, the weight 160 is disposed away from the outer edge of the cover plate 150, that is, the weight 160 is disposed near the central region of the cover plate 150, since the cover plate 150 is coupled with the housing 110 to form the mounting cavity 170, that is, the outer edge of the cover plate 150 is coupled with the housing 110.

It can be understood that the central area of the cover plate 150 has weaker rigidity than the outer edge of the cover plate 150, that is, the weight of the cover plate 150 in the weak rigid area is increased by providing the weight member 160 on the cover plate 150, so as to adjust the weight distribution on the cover plate 150, and further adjust the natural frequency of the cover plate 150, that is, reduce the resonance frequency of the cover plate 150, reduce the transmission of the internal vibration noise to the surface of the housing 110 when the compressor 100 is operated, improve the noise radiation, reduce the overall noise when the compressor 100 is operated, further reduce the overall noise of the air conditioner having the compressor 100, and reduce the noise of the automobile having the air conditioner during the driving process, thereby improving the user experience.

It will be appreciated that the location of the weight 160 is dependent upon the particular shape of the cover plate 150.

As shown in fig. 1, 4, 6, 8 and 10, further, on the basis of any of the above embodiments, the cover plate 150 includes a cover body 151 and a connection portion 152, wherein the connection portion 152 is connected with the cover body 151 and the case 110; the weight 160 is provided on the cover body 151.

In this embodiment, it is defined that the cover plate 150 includes the cover body 151 and the connection portion 152, specifically, the cover body 151 is connected to the connection portion 152, and the cover plate 150 is connected to the housing 110 through the connection portion 152, it can be understood that the connection portion 152 is disposed near the outer edge of the cover body 151, so that the volume of the mounting cavity 170 can be increased, and interference between the cover plate 150 and the electric control portion 140, or between various electric components of the electric control portion 140, can be prevented.

It can be understood that, because the connecting portion 152 is connected with the housing 110, the rigidity of the position where the connecting portion 152 is located is stronger, and the weight 160 is arranged on the cover body 151, that is, the weight 160 is arranged in the weaker rigidity area of the cover plate 150, so that the weight of the weaker rigidity area of the cover plate 150 is increased, the weight distribution on the cover plate 150 is adjusted, the natural frequency of the cover plate 150 is adjusted, that is, the resonance frequency of the cover plate 150 is reduced, the transmission of the internal vibration noise to the surface of the housing 110 during the operation of the compressor 100 is reduced, the noise radiation is improved, the overall noise during the operation of the compressor 100 is reduced, the overall noise of an air conditioner with the compressor 100 is reduced, the noise of an automobile with the air conditioner during the running process is reduced, and the use experience of a user is improved.

In practical application, the cover body 151 and the connecting portion 152 are integrally formed, and it can be understood that the integral structure has good mechanical properties, so that the connection strength between the cover body 151 and the connecting portion 152 can be improved, and the mounting stability of the cover plate 150 can be further improved. In addition, the integrated structure is also convenient for the mass production of the cover plate 150, so that the production efficiency of the cover plate 150 can be improved, the production difficulty of the cover plate 150 can be reduced, and the production cost of the compressor 100 can be further reduced.

As shown in fig. 1, 4, 6, 8 and 10, further, on the basis of the above-described embodiment, the connection portion 152 is disposed near the outer edge of the cap body 151 and the weight 160 is disposed near the center of the cap body 151 in the axial direction of the compression assembly 120.

In this embodiment, the weight 160 is disposed near the center of the cover body 151 along the axial direction of the compression assembly 120, and it can be understood that, since the connecting portion 152 is disposed near the outer edge of the cover body 151 and the connecting portion 152 is connected with the housing 110, the central area of the cover body 151 is weaker than the position of the cover body 151 near the connecting portion 152, that is, the weight of the weak rigid area on the cover body 151 is increased by disposing the weight 160 on the cover body 151, so as to adjust the weight distribution on the cover 150, and thus adjust the natural frequency of the cover 150, that is, reduce the resonant frequency of the cover 150, reduce the transmission of internal vibration noise to the surface of the housing 110 when the compressor 100 is operated, improve the noise radiation, reduce the overall noise when the compressor 100 is operated, and thus reduce the overall noise of the air conditioner with the compressor 100, and reduce the noise of the vehicle with the air conditioner in the driving process, and improve the use experience of the user.

In addition, the connection portion 152 is disposed near the outer edge of the cover body 151, and also increases the volume of the installation cavity 170, preventing interference between the cover plate 150 and the electric control portion 140, or between the electric components of the electric control portion 140.

As shown in fig. 2, 3, 5, 7, 9 and 11, further, on the basis of the above-described embodiment, in the axial direction of the compression assembly 120, the average thickness T1 of the cover body 151 and the maximum value T2 of the thickness of the weight 160 are satisfied, with T1 < T2.

In this embodiment, in the axial direction of the compression assembly 120, the average thickness of the cover body 151 is smaller than the thickness of the weight 160, and in particular, the average thickness of the cover body 151 is much smaller than the thickness of the weight 160. That is, the thickness of the cover body 151 is set to be thinner, and the thickness of the weight 160 is set to be thicker, so that the weight distribution on the cover plate 150 can be effectively adjusted, and then the natural frequency of the cover plate 150 is adjusted, that is, the resonance frequency of the cover plate 150 is reduced, the transmission of internal vibration noise to the surface of the shell 110 when the compressor 100 operates is reduced, the noise radiation is improved, the overall noise when the compressor 100 operates is reduced, and then the overall noise of an air conditioner with the compressor 100 is reduced, and the noise of an automobile with the air conditioner in the driving process is reduced, so that the use experience of a user is improved.

It can be understood that if the weight 160 includes one weight portion 161, T2 is the thickness of one weight portion 161 in the axial direction, and if the weight 160 includes a plurality of weight portions 161 in the axial direction, T2 is the sum of the thicknesses of the plurality of weight portions 161, and as shown in fig. 3, T2 is the sum of T21 and T22. If the thicknesses of the weight 160 are not equal in the axial direction, T2 is the maximum value of the thickness of the weight 160.

As shown in fig. 3 and 9, further, the weight 160 includes a plurality of weight portions 161 on the basis of any of the above embodiments; the plurality of weight parts 161 are arranged on one side of the cover plate 150 facing the compression assembly 120; or a plurality of weight portions 161 are provided on a side of the cover plate 150 facing away from the compression assembly 120; or at least one weight 161 is provided on a side of the cover plate 150 facing the compression assembly 120, and at least one weight 161 is provided on a side of the cover plate 150 facing away from the compression assembly 120.
