[0051] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0052] Reference is made below to Figures 1 - 3 Describe the reciprocating compressor 100 according to the embodiments of the present application, which is applied to a vehicle-mounted refrigerator.

[0053] The reciprocating compressor 100 includes a shell 110, a pump body 120, a drive motor 130 and a wiring part 140.

[0054] In this embodiment, the shell 110 may include a detachable upper shell 111 and a lower shell 112 to facilitate the assembly of the compressor. The upper shell 111 and the lower shell 112 define an installation cavity. The pump body 120 and the drive motor 130 are fixedly installed in the lower shell 112, and the upper shell 111 covers the open end of the lower shell 112 to seal the installation cavity.

[0055] Among them, the lower shell 112 is provided with mounting feet 113 at least at the bottom. The mounting feet 113 may be provided with mounting holes, and the reciprocating compressor 100 may be fixedly installed on the vehicle body through the mounting holes on the mounting feet 113 and bolts.

[0056] The pump body 120 is installed in the shell 110. The pump body 120 includes a pump main body 121 and a crankcase 122 arranged along the first direction. A crankshaft 123 is provided in the crankcase 122. The drive motor 130 is installed on the lower side of the crankcase 122 and is power-coupled to the crankshaft 123.

[0057] In this embodiment, a piston slidable along a first direction may be provided inside the pump body 121. An opening may be provided on the lower side of the crankcase 122 so that one end of the crankshaft 123 can extend out from the opening. The other end of the crankshaft 123 may be connected to the piston through a connecting rod. The output end of the drive motor 130 may be connected to one end of the crankshaft 123 to drive the crankshaft 123 to rotate, and the piston is driven by the crankshaft 123 to perform a reciprocating motion along the first direction, so as to realize the operation of the compressor.

[0058] The wiring part 140 is installed on the first side wall of the housing 110 in a second direction and is electrically connected to the drive motor 130, and the first direction intersects with the second direction.

[0059] The wiring part 140 is installed on the housing 110 and is electrically connected to the drive motor 130. Among them, the part of the wiring part 140 located outside the housing 110 is provided with wiring pins for connecting to an external power supply, so that the external power supply supplies power to the drive motor 130 through the wiring part 140.

[0060] Due to the structural characteristics of the reciprocating compressor 100, the occupied space along the arrangement direction of the pump body 121 and the crankcase 122 is relatively large. Therefore, in the related art, generally, the arrangement direction of the pump body and the crankcase is taken as the length direction of the compressor. When the vehicle-mounted refrigerator is of a long shape, in order to reduce the impact on the volume ratio, generally, the length direction of the compressor is arranged along the width direction of the vehicle-mounted refrigerator to meet the volume ratio requirement. However, in actual assembly, the influence of the control components of the compressor on the assembly space also needs to be considered. Generally, the control components need to be connected to the wiring part. In order to avoid the influence of the control components on the volume ratio of the vehicle-mounted refrigerator, the wiring part is also arranged in the length direction of the housing, resulting in a further increase in the size of the reciprocating compressor in the length direction. Eventually, when the width dimension of the vehicle-mounted refrigerator in some vehicle models is limited, the compressor cannot be installed in the original installation method. If the length direction of the compressor is arranged along the length direction of the vehicle-mounted refrigerator, more of the limited volume of the vehicle-mounted refrigerator will be occupied, further reducing the volume ratio of the vehicle-mounted refrigerator.

[0061] In this embodiment, the wiring portion 140 is installed on the first side wall of the housing 110 in the second direction, and the first direction intersects with the second direction, so that the installation position of the wiring portion 140 is staggered from the arrangement directions of the pump main body 121 and the crankcase 122, thereby reducing the length of the reciprocating compressor 100 in the first direction. In assembly and design, the assembly of the wiring portion 140 in the second direction is more compact, the size increase of the reciprocating compressor 100 in the second direction is small, thus reducing the overall volume, and the sizes of the reciprocating compressor 100 in all directions are closer, which can effectively increase the volume utilization rate of the vehicle-mounted refrigerator. In addition, for various different vehicle models, the wiring methods of the circuit and pipeline are more flexible and the adaptation rate is higher.

[0062] According to the reciprocating compressor 100 provided by the embodiment of the present application, by arranging the wiring portion 140 in the second direction, the length of the reciprocating compressor 100 in the arrangement directions of the pump main body 121 and the crankcase 122 is reduced, the overall structure of the reciprocating compressor 100 is more compact, the volume utilization rate of the vehicle-mounted refrigerator is improved, the size of the vehicle-mounted refrigerator can be better adapted, and the applicable usage scenarios can be increased.

[0063] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, the drive motor 130 may include a stator 131 fixedly installed in the housing 110. The stator 131 may be connected with a connecting component 132. The connecting component 132 may be installed in the first side wall and electrically connected to the wiring portion 140. The rotor 133 is rotatably installed in the stator 131 and may be power-coupled to the crankshaft 123.

[0064] In this embodiment, the stator 131 may be fixedly installed on the lower housing 112 to ensure sufficient stability of the stator 131 during operation. In one example, the lower housing 112 may be provided with positioning posts extending in the up-down direction. The positioning posts penetrate through the stator 131 to position and fix the stator 131. Wherein, the crankcase 122 may also be fixedly connected to the stator 131 to ensure sufficient stability of the crankcase 122 during operation. The rotor 133 is rotatably installed in the stator 131. After the stator 131 is powered on, the rotor 133 is driven to rotate. The rotor 133 may be power-coupled to a part of the crankshaft 123 extending out of the crankcase 123 to drive the crankshaft 123 to rotate through the rotor 133.

[0065] The stator 131 is connected with a connecting component 132, and the connecting component 132 is installed on the inner side of the first side wall and is electrically connected to the wiring part 140. Among them, the coil in the stator 131 is connected to the connecting component 132 through a wire, and then connected to the wiring part 140 through the connecting component 132, and further connected to an external power supply. By arranging the connecting component 132 in the housing 110, the stability of the circuit connection is improved. When the compressor is working, high-frequency vibration will be generated, and the connecting component 132 is not easy to fall off.

[0066] In some embodiments, the first side wall of the housing 110 may be provided with a through hole, at least part of the wiring part 140 penetrates through the through hole into the housing 110, the wiring part 140 is provided with wiring pins corresponding to the outside of the housing 110 in the housing 110, the connecting component 132 is provided with wiring holes, and the wiring pins can extend into the wiring holes so that the connecting component 132 is cooperatively connected with the wiring part 140. It should be noted that the number of wiring pins may be multiple, specifically three, four, five or more, which are not limited herein. Exemplarily, in this embodiment, three wiring pins are provided, and three wiring holes corresponding to the wiring pins are provided on the connecting component 132.

[0067] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, the connecting component 132 may be arranged between the stator 131 and the first side wall, and may be spaced apart from the crankcase 122.

[0068] In this embodiment, a support portion is formed on the circumferential side of the crankcase 122, so the occupied space is relatively large. The outer peripheral wall of the stator 131 is arranged in a plane. By arranging the connecting component 132 between the stator 131 and the first side wall, the assembly space inside the housing 110 is optimized, the size of the reciprocating compressor 100 in the second direction is reduced, and it is possible to avoid that the circumferential vibration of the crankcase 122 during operation is likely to interfere with the connecting component 132.

[0069] Among them, the connecting component 132 may be spaced apart from the stator 131. Since the crankcase 122 is connected to the stator 131, the vibration generated when the crankcase 122 works may drive the stator 131 to vibrate. To reduce the influence of the vibration on the connecting component 132, the connecting component 132 may be spaced apart from the stator 131 to improve the stability of the overall structure.

[0070] According to some embodiments of the present application, the spacing distance M between the connecting component 132 and the crankcase 122 may satisfy:

[0071] 4mm < M ≤ 8mm.

[0072] In this embodiment, the connecting component 132 can be arranged at an interval from the crankcase 122. Since during the operation of the compressor, the main components generating vibration are the pump main body 121 of the pump body 120 and the crankcase 122, by defining the interval distance between the connecting component 132 and the crankcase 122, there is a sufficient safety distance between the connecting component 132 and the crankcase 122 or between the connecting component 132 and the pump main body 121 during the operation of the compressor. Moreover, the distance between the connecting component 132 and the crankcase 122 is not too large to increase the size of the reciprocating compressor 100 in the second direction.

[0073] Among them, the value range of the interval distance M between the connecting component 132 and the crankcase 122 is (4 mm, 8 mm]. Specifically, the interval distance M between the connecting component 132 and the crankcase 122 can take values of 4.5 mm, 5 mm, 6 mm, 7 mm, 8 mm or other values greater than 4 mm and less than or equal to 8 mm, which are not limited herein.

[0074] According to some embodiments of the present application, the height H1 of the connecting component 132 can satisfy: 20 mm ≤ H1 ≤ 32 mm; and / or,

[0075] the length L1 of the connecting component 132 in the first direction can satisfy: 12 mm ≤ L1 ≤ 20 mm; and / or,

[0076] the thickness W1 of the connecting component 132 in the second direction can satisfy: 5 mm ≤ W1 ≤ 10 mm.

[0077] In this embodiment, through the special design of the size of the connecting component 132, the volume of the connecting component 132 is reduced, thereby optimizing the internal space of the housing 110 and reducing the influence on the size in the second direction due to the arrangement of the wiring part 140 in the second direction. While ensuring that the connecting component 132 has sufficient structural strength, the size of the reciprocating compressor 100 in the second direction is reduced, thereby assisting in increasing the volume ratio of the vehicle-mounted refrigerator and the application scenarios of the reciprocating compressor 100.

[0078] Among them, the value range of the height H1 of the connecting component 132 is [20 mm, 30 mm]. Specifically, the height H1 of the connecting component 132 can take values of 20 mm, 21 mm, 23 mm, 25 mm, 26 mm, 27 mm, 28 mm, 30 mm or other values between 20 mm and 30 mm, which are not limited herein.

[0079] Among them, the value range of the length L1 of the connecting component 132 in the first direction is [12 mm, 20 mm]. Specifically, the length L1 in the first direction can take values of 12 mm, 13 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm or other values between 12 mm and 20 mm, which are not limited herein.

[0080] Among them, the value range of the thickness W1 of the connecting component 132 in the second direction is [5 mm, 10 mm]. Specifically, the thickness W1 in the second direction can take values of 5 mm, 6 mm, 6.9 mm, 7.4 mm, 7.9 mm, 8.5 mm, 9 mm, 10 mm or other values between 5 mm and 10 mm, which are not limited herein.

[0081] As Figure 3 shown, according to some embodiments of the present application, the rotor 133 may include a plurality of magnetic parts 134 arranged circumferentially, and the magnetic parts 134 may be made of rare earth materials.

[0082] In this embodiment, the rotor 133 may include a plurality of magnetic parts 134 arranged along its circumference. Specifically, the plurality of magnetic parts 134 are evenly arranged along its circumference to ensure the stability of magnetism. The number of the magnetic parts 134 is not limited herein. Exemplarily, 6 magnetic parts 134 may be provided.

[0083] The magnetic part 134 may be made of rare earth material. The rare earth material has a stronger magnetic field compared with ordinary ferrite, and can reduce the volume of the rotor 133 under the same efficiency, thereby realizing the miniaturization of the drive motor 130, further optimizing the installation space inside the housing 110, and thus reducing the overall volume of the reciprocating compressor 100.

[0084] According to some embodiments of the present application, the outer diameter D of the rotor 133 may satisfy:

[0085] 25 mm ≤ D ≤ 35 mm.

[0086] In this embodiment, by downsizing the outer diameter of the rotor 133 to reduce the size of the drive motor 130, and by limiting the size range of the outer diameter of the rotor 133, while reducing the volume of the rotor 133, the drive motor 130 has sufficient driving force.

[0087] Among them, the value range of the outer diameter D of the rotor 133 is [25 mm, 35 mm]. Among them, the outer diameter D of the rotor 133 can take values of 25 mm, 27 mm, 29 mm, 31 mm, 33 mm, 34 mm, 35 mm or other values between 25 mm and 35 mm, which are not limited herein.

[0088] AsFigure 1 and Figure 2 As shown in Figure 1 and Figure 2 , according to some embodiments of the present application, the reciprocating compressor 100 may further include a limiting component 150, which is provided on the side of the pump body 121 close to the housing 110. The distance S between the limiting component 150 and the housing 110 may satisfy: 2mm ≤ S ≤ 4mm.

[0089] In this embodiment, the limiting component 150 may be made of plastic material, so that when the limiting component 150 collides with the metal housing 110 during the vibration of the pump body 120, the generated noise is small, improving the customer experience.

[0090] By arranging the limiting component 150 on the side of the pump body 121 close to the housing 110, it can play a certain protective role for the pump body 121. Moreover, during the operation of the pump body 120, large vibrations will be generated. By arranging the limiting component 150 between the pump body 121 and the housing 110 and limiting the distance between the limiting component 150 and the housing 110, the vibration amplitude of the pump body 121 can be restricted to a certain extent, and it can further play a certain protective role for the connecting component 132, so as to prevent the large vibration amplitude of the pump body 121 from hitting the connecting component 132, improving the use stability.

[0091] Among them, the value range of the distance S between the limiting component 150 and the housing 110 is [2mm, 4mm]. Among them, the distance S between the limiting component 150 and the housing 110 can take values of 2mm, 2.2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm or other values between 2mm - 4mm, which are not limited herein.

[0092] In some embodiments, as Figure 1 shown, a limiting component 150 may also be provided on the surface of the crankcase 122 close to the housing 110. By arranging the limiting component 150, it can play a certain protective role for the crankcase 122, and at the same time, the vibration amplitude on one side of the crankcase 122 can be limited, further reducing the overall vibration amplitude of the pump body 120 and improving the working stability. Among them, the setting parameters of the limiting component 150 can refer to the foregoing embodiments, which are not limited herein.

[0093] According to the embodiment of the present application, limiting the distance range between the limiting component 150 and the housing 110 can restrict the vibration amplitude of the pump body 121, improve the overall working stability, and can further optimize the internal installation space and reduce the volume.

[0094] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, the wiring part 140 may include a mounting bracket 141, and the mounting bracket 141 is mounted outside the first side wall.

[0095] In this embodiment, an installation bracket 141 may be provided on the outer side of the first side wall. The installation bracket 141 is used to fixedly install a control component. The control component may be a control board, which may be electrically connected to the wiring pins. A power supply may be connected to the control board, and the operation of the motor is controlled by the control board.

[0096] According to some embodiments of the present application, the first direction is the length direction of the housing 110, and the second direction is the width direction of the housing 110.

[0097] In this embodiment, by setting the length direction of the housing 110 as the first direction, the width direction of the housing 110 as the second direction, and arranging the wiring portion 140 on the first side wall in the second direction, the size of the reciprocating compressor 100 in the length direction is reduced, which facilitates the installation of the control component on the wiring portion 140, and also makes the installation method of the reciprocating compressor 100 in the vehicle-mounted refrigerator more flexible. Even if the length direction of the reciprocating compressor 100 is arranged along the length direction of the vehicle-mounted refrigerator, it will not occupy too much space, improving the volume utilization rate of the vehicle-mounted refrigerator.

[0098] According to some embodiments of the present application, the length L2 of the housing 110 satisfies: 100 mm ≤ L2 ≤ 109 mm; and / or, the width W2 of the housing 110 satisfies: 88 mm ≤ W2 ≤ 97 mm; and / or, the height H2 of the housing 110 satisfies: 90 mm ≤ H2 ≤ 100 mm.

[0099] In this embodiment, through the miniaturization design of internal structural components such as the drive motor 130 and the connecting member 132, and by arranging the wiring portion 140 in the width direction of the housing 110 and optimizing the installation space inside the housing 110, while the length of the housing 110 is reduced, the increase in width is not large, the overall volume is smaller, and the application range is wider.

[0100] Among them, the value range of the length L2 of the housing 110 is [100 mm, 109 mm]. Specifically, the length L2 of the housing 110 may take values of 100 mm, 101 mm, 102 mm, 103 mm, 104 mm, 106 mm, 108 mm, 109 mm or other values between 100 mm and 109 mm, which are not limited herein.

[0101] Among them, the value range of the width W2 of the housing 110 is [88 mm, 97 mm]. Specifically, the width W2 of the housing 110 may take values of 88 mm, 89 mm, 90 mm, 91 mm, 93 mm, 95 mm, 96 mm, 97 mm or other values between 88 mm and 97 mm, which are not limited herein.

[0102] Among them, the value range of the height H2 of the housing 110 is [90 mm, 100 mm]. Specifically, the height H2 of the housing 110 can take values such as 90 mm, 91 mm, 93 mm, 95 mm, 96 mm, 97 mm, 98 mm, 100 mm or other values between 90 mm and 100 mm, which are not limited herein.

[0103] The embodiment of the present application also provides a vehicle refrigerator, which includes the reciprocating compressor 100 in any of the foregoing embodiments, and is used to provide power for the refrigerant of the vehicle refrigerator.

[0104] It should be noted that since the vehicle refrigerator in the embodiment of the present application includes the reciprocating compressor 100 in any of the foregoing embodiments, the technical features and technical effects of including the reciprocating compressor 100 in any of the foregoing embodiments will not be elaborated herein.

[0105] In this embodiment, the reciprocating compressor 100 has a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet are connected to the refrigeration circuit of the vehicle refrigerator to provide power for the refrigerant of the vehicle refrigerator and drive the refrigerant in the refrigeration circuit to circulate and refrigerate.

[0106] According to the vehicle refrigerator provided by the embodiment of the present application, by arranging the wiring part 140 of the reciprocating compressor 100 in the second direction, the length of the reciprocating compressor 100 in the arrangement direction of the pump body 121 and the crankcase 122 is reduced, so that the overall structure of the reciprocating compressor 100 is more compact, the volume ratio of the vehicle refrigerator is increased, the size of the vehicle refrigerator can be better adapted, and the applicable usage scenarios can be increased.

[0107] The embodiment of the present application also provides a vehicle, which includes a vehicle body and the vehicle refrigerator in the foregoing embodiment, and the vehicle refrigerator is installed in the vehicle body.

[0108] According to the vehicle of the embodiment of the present application, by reducing the volume of the reciprocating compressor 100 in the vehicle refrigerator, the volume of the vehicle refrigerator can be made smaller, and thus more vehicle models can be adapted, and the application scenarios are more extensive.

[0109] According to some embodiments of the present application, the vehicle refrigerator is arranged between the front seats of the vehicle, the first direction is arranged along the longitudinal direction of the vehicle, and the second direction is arranged along the transverse direction of the vehicle.

[0110] In this embodiment, the vehicle refrigerator can be a front-mounted refrigerator in the vehicle, which can be arranged between the front seats, generally located in the glove box. By arranging the first direction along the longitudinal direction of the vehicle and the second direction along the transverse direction of the vehicle, the length direction of the reciprocating compressor 100 is arranged along the longitudinal direction of the vehicle, and the width direction of the reciprocating compressor 100 is arranged along the transverse direction of the vehicle.

[0111] With the setting of shortening the length direction of the reciprocating compressor 100, the volume occupation of the in-vehicle refrigerator is relatively small, meeting the volume ratio requirement. Moreover, the control component is installed in the width direction of the reciprocating compressor 100, with sufficient installation space, which is convenient for assembly. At the same time, the occupation of the width direction of the in-vehicle refrigerator is also relatively small, enabling it to adapt to a smaller installation space, and it can be adapted to a variety of vehicle models, with a wider application range.
