[0051] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0052] Reference below Figure 1-Figure 3 A reciprocating compressor 100 according to an embodiment of the present application is described as being applied to a vehicle refrigerator.

[0053] The reciprocating compressor 100 includes a housing 110 , a pump body 120 , a driving motor 130 , and a connecting portion 140 .

[0054] In this embodiment, the housing 110 may include a detachably connected upper housing 111 and a lower housing 112 to facilitate assembly of the compressor. The upper housing 111 and the lower housing 112 define an installation cavity, the pump body 120 and the drive motor 130 are fixedly installed on the lower housing 112, and the upper housing 111 is covered at the open portion of the lower housing 112 to seal the installation cavity.

[0055] The lower shell 112 is provided with a mounting foot 113 at least at the bottom, and the mounting foot 113 may be provided with a mounting hole. The reciprocating compressor 100 may be fixedly mounted on the vehicle body through the mounting hole on the mounting foot 113 and bolts.

[0056] The pump body 120 is installed in the housing 110 , and the pump body 120 includes a pump main body 121 and a crankcase 122 arranged along a 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 slidably arranged along a first direction may be provided in the pump body 121, and an opening may be provided on the lower side of the crankcase 122 so that one end of the crankshaft 123 can extend from the opening, and the other end of the crankshaft 123 can be connected to the piston through a connecting rod. The output end of the drive motor 130 can be connected to one end of the crankshaft 123 to drive the crankshaft 123 to rotate, and the piston is driven to perform reciprocating motion along the first direction through the crankshaft 123 to realize the operation of the compressor.

[0058] The wiring portion 140 is installed on the first side wall of the housing 110 in the second direction and is electrically connected to the driving motor 130 . The first direction and the second direction are intersecting.

[0059] The wiring portion 140 is installed on the shell 110 and electrically connected to the drive motor 130 , wherein the portion of the wiring portion 140 located outside the shell 110 is provided with wiring pins, which are used to connect to an external power source so that the external power source can supply power to the drive motor 130 through the wiring portion 140 .

[0060] The reciprocating compressor 100 is limited by its structural characteristics, and the space occupied along the arrangement direction of the pump body 121 and the crankcase 122 is relatively large. Therefore, in the relevant technology, the arrangement direction of the pump body and the crankcase is generally taken as the length direction of the compressor. When the vehicle refrigerator is long, in order to reduce the impact on the volume ratio, it is generally chosen to arrange the length direction of the compressor along the width direction of the vehicle refrigerator to meet the volume ratio requirements. However, in actual assembly, it is also necessary to consider the impact of the control component of the compressor on the assembly space. Generally, the control component needs to be connected to the wiring part. In order to avoid the impact of the control component on the volume ratio of the vehicle refrigerator, the wiring part is also arranged in the length direction of the shell, resulting in further increase in the length direction of the reciprocating compressor. Ultimately, when the width of the vehicle refrigerator of some models is limited, the compressor cannot be installed according to the original installation method. If the length direction of the compressor is arranged along the length direction of the vehicle refrigerator, the already limited volume of the vehicle refrigerator is occupied more, further reducing the volume ratio of the vehicle refrigerator.

[0061] In this embodiment, the wiring portion 140 is installed on the first side wall of the shell 110 in the second direction, and the first direction is intersected with the second direction so that the setting position of the wiring portion 140 is staggered with the arrangement direction of the pump body 121 and the crankcase 122, thereby reducing the length of the reciprocating compressor 100 in the first direction, and in assembly and design, the assembly of the wiring portion 140 in the second direction is made more compact, and the increase in the size of the reciprocating compressor 100 in the second direction is small, thereby reducing the overall volume, and making the sizes of the reciprocating compressor 100 in all directions closer, which can effectively increase the volume ratio of the vehicle refrigerator, and in corresponding to a variety of different vehicle models, the circuit and pipeline wiring methods are more flexible and have a higher adaptability.

[0062] According to the reciprocating compressor 100 provided in the embodiment of the present application, by setting the wiring portion 140 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 improved, the size of the vehicle refrigerator can be better adapted, and the adaptable usage scenarios are increased.

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

[0064] In this embodiment, the stator 131 can be fixedly mounted on the lower housing 112 so that the stator 131 has sufficient stability during operation. In one example, the lower housing 112 can be provided with a positioning column extending in the up-down direction, and the positioning column penetrates the stator 131 to position and fix the stator 131. Among them, the crankcase 122 can also be fixedly connected to the stator 131 so that the crankcase 122 has sufficient stability during operation. The rotor 133 is rotatably mounted in the stator 131. After the stator 131 is powered, the rotor 133 is driven to rotate. The rotor 133 can be coupled to the crankshaft 123 and the part of the crankcase 123 that extends out of the power coupling connection, so that the crankshaft 123 is driven to rotate through the rotor 133.

[0065] The stator 131 is connected to a connecting component 132, which is installed on the inner side of the first side wall and electrically connected to the wiring portion 140. The coil in the stator 131 is connected to the connecting component 132 through a wire, and then connected to the wiring portion 140 through the connecting component 132, and then connected to an external power supply. By arranging the connecting component 132 in the housing 110, the stability of the circuit connection is improved, and high-frequency vibration is generated when the compressor is working, 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 portion 140 passes through the through hole into the housing 110, the wiring portion 140 is provided with wiring pins corresponding to the outside of the housing 110 in the housing 110, and the connecting component 132 is provided with a wiring hole, and the wiring pins can be inserted into the wiring hole so that the connecting component 132 and the wiring portion 140 are matched and connected. It should be noted that the number of wiring pins can be multiple, specifically three, four, five or more, which is not limited here. For example, in this embodiment, three wiring pins are provided, and three wiring holes on the connecting component 132 are provided corresponding to the wiring pins.

[0067] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the connecting component 132 may be disposed 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 peripheral side of the crankcase 122, so that it occupies a larger space. 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 shell 110 is optimized, the size of the reciprocating compressor 100 in the second direction is reduced, and the circumferential vibration of the crankcase 122 during operation can be avoided from interfering with the connecting component 132.

[0069] Among them, the connecting component 132 can be spaced apart from the stator 131. Since the crankcase 122 is connected to the stator 131, the vibration generated when the crankcase 122 is working may drive the stator 131 to vibrate. In order to reduce the impact of the vibration on the connecting component 132, the connecting component 132 can 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 spaced apart from the crankcase 122, because during the operation of the compressor, the main components that generate vibration are the pump body 121 of the pump body 120 and the crankcase 122. By limiting the spacing between the connecting component 132 and the crankcase 122, during the operation of the compressor, there is a sufficient safety distance between the connecting component 132 and the crankcase 122 or the pump body 121. In addition, the distance between the connecting component 132 and the crankcase 122 is not too large, so as to increase the size of the reciprocating compressor 100 in the second direction.

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

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

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

[0076] The thickness W1 of the connection member 132 in the second direction may satisfy: 5 mm ≤ W1 ≤ 10 mm.

[0077] In this embodiment, the size of the connecting component 132 is specially designed to reduce the volume of the connecting component 132, thereby optimizing the internal space of the housing 110 and reducing the influence of the connection portion 140 disposed in the second direction on the size 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 helping to increase the volumetric ratio of the vehicle refrigerator and the application scenarios of the reciprocating compressor 100.

[0078] Among them, the value range of the height H1 of the connecting part 132 is [20mm, 30mm]. Specifically, the height H1 of the connecting part 132 can be 20mm, 21mm, 23mm, 25mm, 26mm, 27mm, 28mm, 30mm or other values ​​between 20mm-30mm, which is not limited here.

[0079] Among them, the length L1 of the connecting part 132 in the first direction ranges from [12mm, 20mm]. Specifically, the length L1 in the first direction can be 12mm, 13mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm or other values ​​between 12mm and 20mm, which are not limited here.

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

[0081] like Figure 3 As shown, according to some embodiments of the present application, the rotor 133 may include a plurality of magnetic portions 134 arranged along the circumferential direction, and the magnetic portions 134 may be made of rare earth material.

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

[0083] The magnetic part 134 can be made of rare earth material. Rare earth material has a stronger magnetic field than ordinary ferrite, which can reduce the volume of the rotor 133 at the same efficiency, thereby realizing the miniaturization of the drive motor 130 and further optimizing the installation space inside the shell 110, thereby 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] 25mm≤D≤35mm.

[0086] In this embodiment, the outer diameter of the rotor 133 is reduced to reduce the size of the drive motor 130, and the size range of the outer diameter of the rotor 133 is limited to reduce the volume of the rotor 133 while ensuring that the drive motor 130 has sufficient driving force.

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

[0088] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the reciprocating compressor 100 may further include a limit assembly 150, which is disposed on the side of the pump body 121 close to the shell 110, and the distance S between the limit assembly 150 and the shell 110 may satisfy: 2mm≤S≤4mm.

[0089] In this embodiment, the limiting component 150 can be made of plastic material, so that when the pump body 120 vibrates and the limiting component 150 collides with the metal shell 110, less noise is generated, thereby improving the customer experience.

[0090] By arranging the limiting assembly 150 on the side of the pump body 121 close to the housing 110, the pump body 121 can be protected to a certain extent. In addition, during the operation of the pump body 120, a large vibration will be generated. By arranging the limiting assembly 150 between the pump body 121 and the housing 110 and limiting the spacing between the limiting assembly 150 and the housing 110, the vibration amplitude of the pump body 121 can be limited to a certain extent, and the connecting component 132 can be further protected to a certain extent, so as to prevent the vibration amplitude of the pump body 121 from being too large and causing impact on the connecting component 132, thereby improving the stability of use.

[0091] Among them, the range of values ​​of the distance S between the limit component 150 and the shell 110 is [2mm, 4mm], among which, the distance S between the limit component 150 and the shell 110 can be 2mm, 2.2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm or other values ​​between 2mm-4mm, which are not limited here.

[0092] In some embodiments, Figure 1 As shown, the surface of the crankcase 122 close to the housing 110 may also be provided with a limit assembly 150. By providing the limit assembly 150, the crankcase 122 is protected to a certain extent, and the vibration amplitude of one side of the crankcase 122 can be limited, thereby further reducing the overall vibration amplitude of the pump body 120 and improving the working stability. The setting parameters of the limit assembly 150 can refer to the aforementioned embodiment and are not limited here.

[0093] According to the embodiment of the present application, the spacing range between the limit assembly 150 and the housing 110 is limited, so that the vibration amplitude of the pump body 121 can be limited, the stability of the overall operation can be improved, and the internal installation space can be further optimized to reduce the volume.

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

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

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

[0097] In this embodiment, the length direction of the shell 110 is set as the first direction, the width direction of the shell 110 is set as the second direction, and the wiring portion 140 is set on the first side wall in the second direction to reduce the size of the reciprocating compressor 100 in the length direction, facilitate the installation of the control component on the wiring portion 140, and make the installation method of the reciprocating compressor 100 in the vehicle refrigerator more flexible. Even if the length direction of the reciprocating compressor 100 is arranged along the length direction of the vehicle refrigerator, it will not take up too much space, thereby improving the volume ratio of the vehicle refrigerator.

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

[0099] In this embodiment, by miniaturizing the internal structural parts such as the drive motor 130 and the connecting component 132, arranging the wiring portion 140 in the width direction of the shell 110, and optimizing the installation space inside the shell 110, the length of the shell 110 is reduced while the width is not increased much, the overall volume is smaller, and the application range is wider.

[0100] Among them, the length L2 of the shell 110 has a value range of [100mm, 109mm]. Specifically, the length L2 of the shell 110 can be 100mm, 101mm, 102mm, 103mm, 104mm, 106mm, 108mm, 109mm or other values ​​between 100mm and 109mm, which are not limited here.

[0101] Among them, the value range of the width W2 of the shell 110 is [88mm, 97mm]. Specifically, the width W2 of the shell 110 can be 88mm, 89mm, 90mm, 91mm, 93mm, 95mm, 96mm, 97mm or other values ​​between 88mm-97mm, which is not limited here.

[0102] Among them, the value range of the height H2 of the shell 110 is [90mm, 100mm]. Specifically, the height H2 of the shell 110 can be 90mm, 91mm, 93mm, 95mm, 96mm, 97mm, 98mm, 100mm or other values ​​between 90mm-100mm, which is not limited here.

[0103] An embodiment of the present application further provides a vehicle refrigerator, which includes a reciprocating compressor 100 as described in any of the aforementioned embodiments, and is used to provide power for a refrigerant in the vehicle refrigerator.

[0104] It should be noted that, because the vehicle refrigerator in the embodiment of the present application includes a reciprocating compressor 100 as in any of the aforementioned embodiments, the technical features and technical effects of the reciprocating compressor 100 as in any of the aforementioned embodiments are not elaborated here.

[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 to the refrigerant of the vehicle refrigerator to drive the refrigerant in the refrigeration circuit to circulate and refrigerate.

[0106] According to the vehicle refrigerator provided by the embodiment itself, by setting the connection part 140 of the reciprocating compressor 100 in the second direction, thereby reducing the length of the reciprocating compressor 100 in the arrangement direction of the pump body 121 and the crankcase 122, the overall structure of the reciprocating compressor 100 is made more compact, and the volume ratio of the vehicle refrigerator is improved. It can better adapt to the size of the vehicle refrigerator and increase the adaptable usage scenarios.

[0107] An embodiment of the present application also provides a vehicle, including a vehicle body and a vehicle refrigerator as described in the above embodiment, wherein 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 smaller, and thus can be adapted to more models of vehicles and have a wider range of application scenarios.

[0109] According to some embodiments of the present application, the vehicle refrigerator is arranged between the front seats of the vehicle, and 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 refrigerator in the vehicle, which can be set between the front seats, generally located in the glove box, by setting the first direction along the longitudinal direction of the vehicle and the second direction along the transverse direction of the vehicle, so that the length direction of the reciprocating compressor 100 is set along the longitudinal direction of the vehicle, and the width direction of the reciprocating compressor 100 is set along the transverse direction of the vehicle.

[0111] By shortening the length direction of the reciprocating compressor 100, the volume of the vehicle refrigerator is less occupied, meeting the volume ratio requirement. In addition, the control component is installed in the width direction of the reciprocating compressor 100, which provides sufficient installation space and facilitates assembly. At the same time, the volume of the vehicle refrigerator is less occupied in the width direction, so it can adapt to a smaller installation space and can be adapted to a variety of vehicle models, with a wider range of applications.
