[0073] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 this utility model, and should not be construed as limiting this utility model.

[0074] The following description, with reference to the accompanying drawings, describes a vehicle-mounted refrigerator according to an embodiment of the present invention.

[0075] like Figures 1-3 As shown, the vehicle refrigerator according to an embodiment of the present invention includes a storage box 20 with a heat preservation module.

[0076] The storage compartment 20 is detachably connected to the refrigerant subsystem, which includes a compressor connected to the vehicle’s in-vehicle heat exchanger 11 or independent of the vehicle’s thermal management system.

[0077] The compressor is used to compress the refrigerant, turning it into a high-temperature, high-pressure refrigerant, and it also drives the flow of the refrigerant.

[0078] The storage box 20 is equipped with an insulation module, which enhances the insulation function of the storage box 20. After the storage box 20 is removed from the refrigerant subsystem, the insulation module can isolate the storage box 20 from the external heat to a certain extent, thereby improving the insulation performance of the storage box 20.

[0079] Specifically, after the storage box 20 is separated from the refrigerant subsystem, it can be used as an insulated box. At this time, the storage box 20 can be conveniently taken to various scenarios, such as when users go on a road trip or have a picnic outdoors, so as to make full use of the storage box.

[0080] In some embodiments, such as Figure 1 As shown, the refrigerant subsystem is the refrigerant subsystem in the vehicle's thermal management system. This refrigerant subsystem can regulate the cabin temperature through the in-vehicle heat exchanger 11 on the one hand, and cool the storage box 20 on the other hand. At this time, the vehicle refrigerator and the vehicle's thermal management system share a compressor 12.

[0081] In other embodiments, the refrigerant subsystem is independent of the vehicle's thermal management system; that is, the refrigerant subsystem and the vehicle's thermal management system are two different systems.

[0082] For example, the vehicle includes a first refrigerant subsystem and a second refrigerant subsystem. The first refrigerant subsystem includes a first compressor and is detachably connected to the storage box 20. The first refrigerant subsystem is used to cool the storage box 20.

[0083] The second refrigerant subsystem belongs to the vehicle's thermal management system. The second refrigerant subsystem includes a second compressor. The second refrigerant subsystem regulates the cabin temperature through the in-vehicle heat exchanger 11. At this time, the vehicle refrigerator and the vehicle's thermal management system use different compressors.

[0084] According to the embodiments of the present invention, the vehicle refrigerator allows the storage box 20 to be separated from the refrigerant subsystem and used as an insulated box, making it convenient to take the storage box 20 to various scenarios, suitable for users to take on road trips, have picnics outdoors, etc., so as to make full use of the storage box 20 and improve the utilization rate of resources.

[0085] The following description, with reference to the accompanying drawings, describes a vehicle-mounted refrigerator according to a specific embodiment of the present invention.

[0086] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the vehicle refrigerator includes a storage box 20 with an insulation module.

[0087] In some embodiments of this utility model, the storage box 20 includes a first connector 201 and a second connector 202. The first connector 201 is detachably connected to the refrigerant subsystem, and the second connector 202 is detachably connected to the refrigerant subsystem. After the first connector 201 is detached from the refrigerant subsystem and the second connector 202 is detached from the refrigerant subsystem, the storage box 20 and the refrigerant subsystem can be separated. At this time, the storage box 20 can be used as an insulated box, making it convenient to take the storage box to various scenarios.

[0088] In some optional embodiments of this utility model, a switch valve is provided at both the first connector 201 and the second connector 202 to control their opening and closing. The opening and closing valve can control the on / off of the storage box 20 and the refrigerant subsystem, and can also open or close the first connector 201 and the second connector 202.

[0089] Specifically, after the storage box 20 is separated from the refrigerant subsystem, the switching valve can be closed to shut off the first connector 201 and the second connector 202 to prevent dust and other contaminants from entering the storage box 20 through the first connector 201 and the second connector 202.

[0090] In some embodiments of this utility model, the insulation module is an insulation layer that covers at least a portion of the body 26 of the storage box 20.

[0091] The box 26 defines the storage space, where food, beverages, etc. can be placed. The insulation layer can isolate the storage box 20 from the outside heat to a certain extent, prolonging the insulation time of the storage box 20 and improving the insulation performance of the storage box 20.

[0092] The thermal management system 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0093] like Figure 1 As shown, the thermal management system 1 according to an embodiment of the present invention includes a refrigerant subsystem and a storage tank 20.

[0094] The refrigerant subsystem includes a compressor 12, which is used to compress the refrigerant to turn it into a high-temperature and high-pressure refrigerant. At the same time, the compressor can drive the refrigerant to flow, so that the refrigerant flows in the refrigerant subsystem. During the circulation of the refrigerant, the refrigerant will release and absorb heat.

[0095] The storage box 20 is detachably connected to the refrigerant subsystem so that the refrigerant in the refrigerant subsystem can be used to cool the storage box 20. In other words, in this embodiment, the compressor 12 in the vehicle's thermal management system is used to cool the storage box 20. There is no need to set up a separate compressor for the cooling of the storage box 20, which makes it easier to make full use of the refrigerant and improve the utilization rate of resources.

[0096] The storage box 20 has an insulation module, which enhances the insulation function of the storage box 20. After the storage box 20 is removed from the refrigerant subsystem, the insulation module can isolate the storage box 20 from the external heat to a certain extent, thereby improving the insulation performance of the storage box 20.

[0097] Specifically, after separating the storage box 20 from the refrigerant subsystem, the storage box 20 can be used as an insulated box, and at the same time, it is convenient to carry the storage box 20 to the required scenario.

[0098] In some embodiments, a storage box 20 is provided in the vehicle. However, as a refrigeration device, the storage box 20 needs to refrigerate for a certain period of time to meet the user's needs. But the mobility of the vehicle and the limited energy resources mean that the storage box 20 cannot be kept in continuous operation. After the driver parks, the storage box 20 is often powered on and off along with the vehicle's power cycle. For users traveling short distances, the storage box 20 often finishes its refrigeration task just before the user has to lock the car to do other things, which is a huge waste of energy, making the storage box 20 seem rather useless.

[0099] To address this issue, this embodiment allows the storage box 20 to be separated from the refrigerant subsystem and used as an insulated box, suitable for users to use during road trips, outdoor picnics, etc., so as to make full use of the storage box 20 and improve resource utilization.

[0100] Therefore, the thermal management system 1 according to the present utility model allows the storage box 20 to be separated from the refrigerant subsystem and used as an insulated box, which is suitable for users to go on road trips, have picnics outdoors, etc., so as to make full use of the storage box 20 and improve the utilization rate of resources.

[0101] The thermal management system 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0102] In some specific embodiments of this utility model, such as Figure 1 As shown, the thermal management system 1 includes a refrigerant subsystem and a storage tank 20.

[0103] In some embodiments of this utility model, when the storage box 20 is separated from the refrigerant subsystem, the refrigerant subsystem circulates independently to ensure the integrity of the refrigerant during circulation within the refrigerant subsystem.

[0104] In some embodiments, the refrigerant subsystem includes an in-vehicle heat exchanger 11, which is used to regulate the temperature of the vehicle cabin. When the storage box 20 is separated from the refrigerant subsystem, the refrigerant subsystem can still use the in-vehicle heat exchanger 11 to cool or heat the vehicle cabin 801.

[0105] Specifically, when the refrigerant flows through the in-vehicle heat exchanger 11 and becomes hot at the heat exchanger 11, it can release heat into the vehicle compartment 801, thereby heating the vehicle compartment 801. When the refrigerant flows through the in-vehicle heat exchanger 11 and absorbs heat at the heat exchanger 11, the refrigerant can absorb heat from the vehicle compartment 801, thereby cooling the vehicle compartment 801.

[0106] In some embodiments of this utility model, such as Figures 2-6 As shown, the refrigerant subsystem includes a first connecting pipe 101 and a second connecting pipe 102, and the storage box 20 includes a first connector 201 and a second connector 202. The first connecting pipe 101 and the first connector 201 are detachably connected, and the second connecting pipe 102 is detachably connected to the second connector 202, so as to realize the detachable connection between the storage box 20 and the refrigerant subsystem.

[0107] Specifically, when the first connecting pipe 101 is connected to the first connector 201 and the second connecting pipe 102 is connected to the second connector 202, the refrigerant in the refrigerant subsystem can flow through the storage box 20, thereby cooling the storage box 20. When the first connecting pipe 101 is separated from the first connector 201 and the second connecting pipe 102 is separated from the second connector 202, the storage box 20 can be separated from the refrigerant subsystem. At this time, the storage box 20 can be flexibly placed in the required scenario and used as an insulated box.

[0108] In some optional embodiments of this utility model, a switch valve is provided at both the first connector 201 and the second connector 202 to control their opening and closing, thereby controlling the opening and closing of the first connector 201 and the second connector 202, and controlling the connection and disconnection between the first connector 201 and the first connecting pipe 101, and between the second connector 202 and the second connecting pipe 102.

[0109] In some optional embodiments of this utility model, the first connecting pipe 101 and the second connecting pipe 102 are both provided with control valves to control their on / off state, so as to avoid refrigerant leakage in the refrigerant subsystem, enable the refrigerant subsystem to circulate independently, and thus regulate the temperature inside the vehicle cabin 801 when the refrigerant flows through the vehicle heat exchanger 11 of the refrigerant subsystem.

[0110] In some embodiments, the control valve may be a solenoid valve, an expansion valve, or a check valve, without further restrictions.

[0111] In some optional embodiments of this utility model, such as Figure 1 As shown, the refrigerant subsystem also includes a storage module. The first connecting pipe 101 is connected to the first port of the compressor 12, the second port of the compressor 12 is connected to the storage module, and the second connecting pipe 102 is connected to the storage module. One of the first port and the second port of the compressor 12 is an intake port, and the other is an exhaust port.

[0112] When the first connecting pipe 101 is connected to the first connector 101 and is conductive, and the second connecting pipe 102 is connected to the second connector 102 and is conductive, the refrigerant is suitable for circulating in the compressor, storage module, and storage box 20, thereby enabling the refrigeration of the storage box 20.

[0113] In some specific embodiments of this utility model, the thermal management system 1 includes an extraction mode. In the extraction mode, the second connecting pipe 102 is disconnected from the second connector 202, and the compressor 12 is operated to store the refrigerant in the storage box 20 into the storage module. This is to store the refrigerant in the storage box 20 in the storage module before separating the storage box 20 from the refrigerant subsystem, thereby preventing refrigerant leakage from the first connector 201 and / or the second connector 202.

[0114] Specifically, in the extraction mode, the control valve closes the second connecting pipe 102, at which time the second connecting pipe 102 is disconnected from the second connector 202. At the same time, the compressor 12 drives the refrigerant in the storage box 20 to flow along the first connecting pipe 101 through the compressor 12 to the storage module, thereby storing the refrigerant originally located in the storage box 20 in the storage module. After all the refrigerant in the storage box 20 has flowed out, the on / off valve closes the first connecting pipe 101, at which time the first connecting pipe 101 and the first connector 201 are disconnected.

[0115] Then, the first connector 201 can be separated from the first connecting pipe 101, and the second connector 202 can be separated from the second connecting pipe 102, thus separating the storage box 20 from the refrigerant subsystem. Specifically, since the on-off valve closes the first connecting pipe 101 and the second connecting pipe 102 before separating the storage box 20 from the refrigerant subsystem, leakage of refrigerant from the ends of the first connecting pipe 101 and the second connecting pipe 102 in the refrigerant subsystem can be prevented.

[0116] In some embodiments, such as Figure 1 As shown, the first connecting pipe 101 is equipped with a first control valve 71 at its end. The first connecting pipe 101 and the first connector 201 are detachably connected. When the first control valve 71 is opened, the first connecting pipe 101 and the first connector 201 are connected. The second connecting pipe 102 is equipped with a second control valve 72 at its end. The second connecting pipe 102 and the second connector 202 are detachably connected. When the second control valve 72 is opened, the second connecting pipe 102 and the second connector 202 are connected.

[0117] When the storage box 20 is used in a vehicle, when the user signals that the storage box 20 needs to be removed from the vehicle, if the vehicle is stopped at this time, the thermal management system 1 switches to the extraction mode. At this time, the second control valve 72 closes the second connecting pipe 102, and the compressor 12 drives the refrigerant in the storage box 20 to flow through the first connecting pipe 101 and into the storage module. After the compressor 12 extracts the refrigerant from the storage box 20, the first control valve 71 closes the first connecting pipe 101. At this time, the first connecting pipe 101 can be separated from the first connector 201, and the second connecting pipe 102 can be separated from the second connector 202, so that the storage box 20 is separated from the refrigerant subsystem, and then the storage box 20 can be removed from the vehicle.

[0118] In some examples, the refrigerant subsystem also includes an external heat exchanger 14 and an internal heat exchanger 11. The internal heat exchanger 11 is used to regulate the temperature of the vehicle compartment 801 so as to cool or heat the vehicle compartment 801. The external heat exchanger 14 is connected between the compressor 12 and the storage module. One end of the second connecting pipe 102 is connected to the storage module, and the other end is connected to the storage box 20 through the first expansion valve and the second connector 202. One end of the first connecting pipe 101 is connected to the compressor 12, and the other end is connected to the storage box 20 through the first control valve 71 and the first connector 201.

[0119] Wherein, the first connecting pipe 101 is connected to and conducts through the first connector 201, and the second connecting pipe 102 is connected to and conducts through the second connector 202. When the storage box 20 needs to be refrigerated, the refrigerant is suitable to circulate in the compressor 12-external heat exchanger 14-first expansion valve-storage box 20-compressor 12.

[0120] The compressor 12 is used to compress gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the external heat exchanger 14, it releases heat and becomes high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows through the first expansion valve, and is throttled and depressurized by the first expansion valve to become low-temperature and low-pressure liquid refrigerant. When the low-temperature and low-pressure liquid refrigerant flows through the storage tank 20, it absorbs heat from the storage tank 20 and becomes low-temperature gaseous refrigerant. The low-temperature gaseous refrigerant flows to the compressor 12, and the compressor 12 compresses the low-temperature gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, thereby realizing the circulation of refrigerant.

[0121] The refrigerant absorbs heat from the storage box 20 as it flows through it, thereby cooling the storage box 20.

[0122] Furthermore, the first expansion valve defines the second control valve 72, meaning that the first expansion valve can not only be used to throttle and reduce the pressure of the refrigerant, but also control the opening or closing of the second connecting pipe 102.

[0123] When it is necessary to separate the storage box 20 from the refrigerant subsystem, the first expansion valve closes the second connecting pipe 102, disconnecting the second connecting pipe 102 from the second connector 202. At this time, the compressor 12 is driven, driving the refrigerant in the storage box 20 to flow along the first connecting pipe 101 through the compressor 12 and then into the storage module. After the compressor 12 extracts the refrigerant from the storage box 20, the second control valve 72 closes the first connecting pipe 101. At this time, the first connecting pipe 101 can be separated from the first connector 201, and the second connecting pipe 102 can be separated from the second connector 202, so that the storage box 20 can be separated from the refrigerant subsystem, and then the storage box 20 can be removed from the vehicle.

[0124] In some specific embodiments of this utility model, the storage box 20 further includes a first heat exchanger, a first pipe 91 and a second pipe 92 connected to the first heat exchanger.

[0125] The first pipe 91 is connected to the first connecting pipe 101 through the first connector 201, and the second pipe 92 is connected to the second connecting pipe 102 through the second connector 202. The refrigerant in the refrigerant subsystem can enter the first heat exchanger through the second pipe 92, and after flowing through the first heat exchanger, it flows to the compressor 12 through the first pipe 91.

[0126] When the refrigerant flows through the first heat exchanger, it can absorb heat from the vicinity of the first heat exchanger, thereby cooling the air near the first heat exchanger and achieving cooling of the storage box 20.

[0127] In some specific embodiments of this utility model, the storage module is a liquid storage tank 13, which can store refrigerant in the liquid storage tank 13. At the same time, the first connecting pipe 101 is reconnected to the first connector 201, the second connecting pipe 102 is reconnected to the second connector 202, the first control valve 71 opens the first connecting pipe 101, and the second control valve 72 opens the second connecting pipe 102. When these conditions are met, the compressor 12 can drive the refrigerant in the liquid storage tank 13 to flow to the storage box 20, so that the storage box 20 can be cooled again.

[0128] In some embodiments, the refrigerant subsystem includes an external heat exchanger 14 connected between the second port of the compressor 12 and the liquid receiver 13, and an internal heat exchanger 11 connected between the first port of the compressor 12 and the storage module, so that the refrigerant stored in the liquid receiver 13 can flow to the internal heat exchanger 11 or the external heat exchanger 14. In this way, after the storage box 20 is separated from the refrigerant subsystem, the refrigerant stored in the liquid receiver 13 can still participate in the independent circulation of the refrigerant subsystem to improve the utilization rate of the refrigerant.

[0129] In some embodiments, such as Figure 1 As shown, a fan 63 is provided at the corresponding position of the external heat exchanger 14, which facilitates the improvement of the heat dissipation efficiency of the external heat exchanger 14.

[0130] In some embodiments, a throttling control valve 73 is provided between the external heat exchanger 14 and the internal heat exchanger 11.

[0131] When it is necessary to raise the temperature of the cabin 801, the first port of the compressor 12 is the exhaust port, the second port of the compressor 12 is the intake port, and the refrigerant is suitable for circulating in the compressor 12-in-cabin heat exchanger 11-throttle control valve 73-out-of-cabin heat exchanger 14-compressor 12.

[0132] The compressor 12 is used to compress gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the in-vehicle heat exchanger 11, it releases heat and becomes high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows through the throttling control valve 73, and the pressure is reduced by the throttling control valve 73 to become low-temperature and low-pressure liquid refrigerant. When the low-temperature and low-pressure liquid refrigerant flows through the outside heat exchanger 14, it absorbs heat from the outside of the vehicle and becomes low-temperature gaseous refrigerant. The low-temperature gaseous refrigerant flows to the compressor 12, and the compressor 12 compresses the low-temperature gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, thereby realizing the circulation of refrigerant.

[0133] When the refrigerant flows through the vehicle heat exchanger 11, it can release heat into the vehicle compartment 801, thereby heating the vehicle compartment 801 and raising the temperature inside the vehicle compartment 801.

[0134] When it is necessary to reduce the temperature of the cabin 801, the second port of the compressor 12 is the exhaust port, the first port of the compressor 12 is the intake port, and the refrigerant is suitable for circulating in the compressor 12-external heat exchanger 14-throttle control valve 73-internal heat exchanger 11-compressor 12.

[0135] The compressor 12 is used to compress gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the external heat exchanger 14, it releases heat and becomes high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows through the throttling control valve 73, and the pressure is reduced by the throttling control valve 73 to become low-temperature and low-pressure liquid refrigerant. When the low-temperature and low-pressure liquid refrigerant flows through the internal heat exchanger 11, it absorbs heat from the vehicle compartment 801 and becomes low-temperature gaseous refrigerant. The low-temperature gaseous refrigerant flows to the compressor 12, and the compressor 12 compresses the low-temperature gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, thereby realizing the circulation of refrigerant.

[0136] The refrigerant absorbs heat from the vehicle compartment 801 when it flows through the heat exchanger 11, thereby cooling the vehicle compartment 801 and reducing the temperature inside the vehicle compartment 801.

[0137] In some examples, the refrigerant subsystem includes a first refrigerant flow path and a second refrigerant flow path, the first refrigerant flow path including a first connecting pipe 101 and a second connecting pipe 102.

[0138] When the storage box 20 needs to be refrigerated, the refrigerant is suitable to flow in the first refrigerant flow path. At this time, the first connecting pipe 101 is connected to the first connector 201 and is conductive, and the second connecting pipe 102 is connected to the second connector 202 and is conductive. The flow path of the refrigerant is compressor 12-external heat exchanger 14-first expansion valve-storage box 20-compressor 12.

[0139] When it is necessary to adjust the temperature of the vehicle compartment 801, the refrigerant flows in the second refrigerant flow path. The flow path of the refrigerant in the second refrigerant flow path includes compressor 12 - external heat exchanger 14 - throttling control valve 73 - internal heat exchanger 11. The flow path of the refrigerant in the second refrigerant flow path also includes compressor 12 - internal heat exchanger 11 - throttling control valve 73 - external heat exchanger 14.

[0140] In some specific embodiments of the present invention, such as Figure 1 As shown, the thermal management system 1 also includes a flow detector, which is used to detect the amount of refrigerant in the storage tank 20. When the thermal management system 1 is in the extraction mode, after the refrigerant in the storage tank 20 is completely extracted, the information is fed back to the user, reminding the user that the first connector 201 can be separated from the first connecting pipe 101 and the second connector 202 can be separated from the second connecting pipe 102.

[0141] When the flow detector detects that the amount of refrigerant in the storage box 20 is lower than a first preset value, the compressor 12 is adapted to stop running after a predetermined time, and the first connecting pipe 101 and the first connector 201 are adapted to disconnect after the compressor stops running.

[0142] Specifically, in the extraction mode, the control valve closes the second connecting pipe 102, at which time the second connecting pipe 102 is disconnected from the second connector 202. At the same time, the compressor 12 drives the refrigerant in the storage box 20 to flow along the first connecting pipe 101 through the compressor 12 to the storage module, thereby storing the refrigerant originally located in the storage box 20 in the storage module. When the flow detector detects that the refrigerant in the storage box 20 is lower than the preset value, the compressor 12 is adapted to stop running after a predetermined time. The on-off valve is disconnected after the compressor stops running to close the first connecting pipe 101.

[0143] Then, the first connector 201 can be separated from the first connecting pipe 101, and the second connector 202 can be separated from the second connecting pipe 102, thus separating the storage box 20 from the refrigerant subsystem. Specifically, since the on-off valve closes the first connecting pipe 101 and the second connecting pipe 102 before separating the storage box 20 from the refrigerant subsystem, leakage of refrigerant from the ends of the first connecting pipe 101 and the second connecting pipe 102 in the refrigerant subsystem can be prevented.

[0144] In some embodiments, when the flow detector detects that the amount of refrigerant in the storage box 20 is a preset value, the compressor 12 and the fan 63 are turned off after 3 seconds.

[0145] The preset value can be 0 or close to 0.

[0146] In some embodiments, the flow detector is a pressure sensor 30 located at the first connector 201.

[0147] When the pressure sensor 30 detects that the pressure at the first connector 201 is 0 or infinitely close to 0, the amount of refrigerant in the storage box 20 is a preset value, reminding the user that the first connector 201 can be separated from the first connecting pipe 101 and the second connector 202 can be separated from the second connecting pipe 102.

[0148] In some specific embodiments of the present invention, the external heat exchanger 14, the liquid storage tank 13 and the compressor 12 are located in the front compartment 802 of the vehicle.

[0149] The following describes a vehicle according to some embodiments of the present invention. The vehicle according to embodiments of the present invention includes a vehicle body and a vehicle-mounted refrigerator according to the above embodiments of the present invention.

[0150] The vehicle body is equipped with a cabin 801, and a storage box 20 is located in the cabin 801 for use by the driver and passengers. The storage box 20 can be used as an insulated box after being separated from the refrigerant subsystem, and it is also convenient for users to take the portable storage box 20 to the required location.

[0151] According to the vehicle of the present invention, by utilizing the vehicle refrigerator of the above embodiment of the present invention, the storage box 20 can be separated from the refrigerant subsystem and used as an insulated box, making it convenient to take the storage box 20 to various scenarios, suitable for users to take on road trips, picnics outdoors, etc., so as to make full use of the storage box 20 and improve the utilization rate of resources.

[0152] The following describes a vehicle according to some other embodiments of the present invention. The vehicle according to an embodiment of the present invention includes a body and a thermal management system 1 according to the above embodiments of the present invention.

[0153] The vehicle body is equipped with a cabin 801, and an in-vehicle heat exchanger 11 is used to regulate the temperature of the cabin 801 to bring the temperature inside the cabin 801 to a suitable range, thereby improving the comfort of the driver and passengers. A storage box 20 is located inside the cabin 801 for the use of the driver and passengers.

[0154] When the storage box 20 is separated from the refrigerant subsystem, it can be used as an insulated box, and it is also convenient for users to take the portable storage box 20 to the required location.

[0155] The vehicle according to the present invention utilizes the thermal management system 1 according to the above embodiment of the present invention, which allows the storage box 20 to be separated from the refrigerant subsystem and used as an insulated box, making it suitable for users to take self-driving tours, have outdoor picnics, etc., so as to make full use of the storage box 20 and improve the utilization rate of resources.

[0156] In some embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the vehicle also includes a housing 40 fixed to the vehicle body. The storage box 20 is detachably disposed in the receiving cavity 401 of the housing 40. The housing 40 is used to limit the position of the storage box 20 so as to reduce the probability of displacement of the storage box 20 during vehicle movement, reduce the amplitude of shaking of the storage box 20, and thus ensure a stable connection between the storage box 20 and the refrigerant subsystem.

[0157] In some optional embodiments of this utility model, the housing 40 is provided with a first positioning part, and the storage box 20 is provided with a second positioning part. The first positioning part and the second positioning part can be separated and cooperated to position the storage box 20, so as to limit the position of the storage box 20 and thus ensure the stable connection between the storage box 20 and the refrigerant subsystem.

[0158] In some specific embodiments of this utility model, such as Figure 10 , Figure 12 As shown, the first positioning part includes a reciprocating slider 411, and the second positioning part includes a groove 211. The slider 411 can extend into the groove 211 to position the storage box 20, thereby limiting the position of the storage box 20.

[0159] like Figure 10 As shown, the storage box 20 is detachably disposed in the receiving cavity 401 along the first direction, and the slider 411 is movable along the second direction. The storage box 20 has a groove 211 on the side wall in the second direction. When the slider 411 moves toward the storage box 20 along the second direction, it is suitable to extend into the groove 211 and abut against the two groove side walls of the groove 211 in the first direction, thereby limiting the position of the storage box 20 in the first direction and reducing the possibility that the storage box 20 may accidentally slide out of the receiving cavity 401.

[0160] When it is necessary to remove the storage box 20 from the receiving cavity 401, the slider 411 is moved away from the storage box 20 in the second direction, and the slider 411 is removed from the groove 211, thereby disengaging the slider 411 from the groove 211.

[0161] In some examples, the first direction extends along the front-back direction and the second direction extends along the left-right direction. The slider 411 is adapted to move in the left-right direction. When the slider 411 engages with the groove 211, the slider 411 extends into the groove 211 and abuts against the front and rear groove walls of the groove 211, thereby limiting the position of the storage box 20 in the front-back direction.

[0162] Furthermore, such as Figure 10 As shown, at least one groove 211 is provided on both the left and right side walls of the storage box 20. The first positioning part includes at least two sliders 411. The two sliders 411 are located on the left and right sides of the storage box 20. When the sliders 411 are matched with the grooves 211 one by one, the storage box 20 is clamped between the two sliders 411, thereby limiting the position of the storage box 20 in the left and right directions.

[0163] In some embodiments, such as Figure 9 , Figure 12 As shown, the first positioning part also includes a positioning groove 412, and the second positioning part also includes a positioning protrusion 212. The positioning protrusion 212 is adapted to cooperate with the positioning groove 412 to position the storage box 20. The moving direction of the slider 411 is intersected with the protruding direction of the positioning protrusion 212, so as to limit the position of the storage box 20 by the cooperation of the slider 411 and the groove 211, and guide the installation direction of the storage box 20 by the cooperation of the positioning protrusion 212 and the positioning groove 412, and at the same time determine whether the storage box 20 is installed in place in the receiving cavity 401.

[0164] In some embodiments, such as Figure 9 As shown, the positioning protrusion 212 protrudes in the vertical direction, the positioning groove 412 extends in the front-back direction, and the storage box 20 is detachably disposed in the receiving cavity 401 in the front-back direction. The cooperation of the positioning protrusion 212 and the positioning groove 412 is suitable for guiding the disassembly and installation direction of the storage box 20, so as to smoothly install the storage box 20 into the receiving cavity 401 or remove the storage box 20 from the receiving cavity 401.

[0165] The positioning groove 412 has an open opening, and the positioning protrusion 212 is adapted to enter the positioning groove 412 through the open opening. The positioning groove 412 has a stop on the side away from the open opening. When the storage box 20 is installed into the receiving cavity 401 in the front-to-back direction, the positioning protrusion 212 enters the positioning groove 412 from the open opening. The cooperation between the positioning protrusion 212 and the positioning groove 412 can guide the installation direction of the storage box 20. When the positioning protrusion 212 abuts against the stop, the storage box 20 is installed in place.

[0166] At the same time, when the positioning protrusion 212 abuts against the stop, the slider 411 and the groove 211 correspond in the left and right direction. When the slider 411 moves in the left and right direction, it can extend into the groove 211 to abut against the front and rear groove walls of the groove 211, thereby limiting the position of the storage box 20 in the front and rear direction.

[0167] In some optional embodiments of this utility model, such as Figure 6 , Figure 7 As shown, the refrigerant subsystem includes a first connecting pipe 101 and a second connecting pipe 102, and the storage box 20 includes a first connector 201 and a second connector 202. The first connecting pipe 101 and the first connector 201 are detachably connected, and the second connecting pipe 102 and the second connector 202 are detachably connected, so as to realize the separation of the storage box 20 from the refrigerant subsystem and facilitate the portable transport of the storage box 20 to the required location.

[0168] The vehicle also includes a first connector 51, which is used to fix the first connecting pipe 101 to the first connector 201 and the second connecting pipe 102 to the second connector 202, so that the first connecting pipe 101 and the first connector 201 are connected, and the second connecting pipe 102 and the second connector 202 are connected, thereby allowing the refrigerant to flow through the storage box 20 and cool the storage box 20.

[0169] Specifically, since the vehicle may experience bumps and jolting during movement, the first connecting pipe 101 and the first connector 201 can be detached and connected separately. Therefore, the first connecting piece 51 is used to fix the first connecting pipe 101 and the first connector 201 together, reducing the possibility of accidental detachment. The second connecting pipe 102 and the second connector 202 can be detached and connected separately. Therefore, the first connecting piece 51 is used to fix the second connecting pipe 102 and the second connector 202 together, reducing the possibility of accidental detachment and improving the stability of the connection between the storage box 20 and the refrigerant subsystem.

[0170] In some optional embodiments of this utility model, such as Figure 6 , Figure 7 As shown, the first connecting pipe 101 is connected to the first connector 201 through the first mating part 15. The first connector 51 is used to connect the first mating part 15 and the first connector 201 to fix the first mating part 15 and the first connector 201 together, ensuring stable connection between the first connecting pipe 101 and the first connector 201 and reducing the possibility of accidental detachment of the first mating part 15 and the first connector 201.

[0172] When it is necessary to separate the first connecting pipe 101 from the first connector 201, the first connecting member 51 should be operated to loosen the connection between the first mating part 15 and the first connector 201, so that the first mating part 15 can be separated from the first connector 201, and the first connecting pipe 101 can be separated from the first connector 201.

[0173] In some specific embodiments of the present invention, the first connector 51 includes a connecting part 511 and a handle part 512. The connecting part 511 is adapted to thread the first connector 201 and the first mating part 15 together to connect the first connector 201 and the first mating part 15 together, thereby achieving stable docking of the first connector 201 and the first mating part 15, and thus realizing the conduction between the first connector 201 and the first connecting pipe 101.

[0174] The handle 512 is located on the side of the connecting part 511 facing away from the first connector 201. The extension direction of the handle 512 intersects the extension direction of the connecting part 511. The first connecting member 51 can be rotated by the handle 512, thereby enabling the connecting part 511 to engage with the first connector 201 and the first mating part 15, or disengaging the connecting part 511 from the first connector 201 and the first mating part 15, thus fixing or loosening the first connector 201 and the first mating part 15.

[0175] The first connector 51 is equipped with an operable handle 512. When the user needs to separate the first connector 201 from the first connecting pipe 101 or connect the first connector 201 to the first connecting pipe 101, he / she only needs to rotate the first connector 51 through the handle 512 without the need for other tools, which is convenient to operate.

[0176] In some embodiments, the first connector 51 further includes a clamping portion 513, which is located between the connecting portion 511 and the handle portion 512, and the diameter of the clamping portion 513 is larger than the diameter of the connecting portion 511.

[0177] The connecting part 511 is adapted to be threaded into the first connector 201, and the clamping part 513 clamps the first mating part 15 to fix the first connector 201 and the first mating part 15 together.

[0178] In some optional embodiments of this utility model, such as Figure 6 , Figure 7As shown, the second connecting pipe 102 is connected to the second connector 202 through the second mating part 16. The first connecting member 51 is used to connect the second mating part 16 and the second connector 202 to fix the second mating part 16 and the second connector 202 together, ensuring stable connection between the second connecting pipe 102 and the second connector 202, and reducing the possibility of accidental detachment of the second mating part 16 and the second connector 202.

[0179] In some examples, the second connecting pipe 102 is fixedly connected to the second mating part 16, the second mating part 16 is mated to the second connector 202, and the first connecting piece 51 connects the second mating part 16 and the second connector 202.

[0180] When it is necessary to separate the second connecting pipe 102 from the second connector 202, the first connecting member 51 should be operated to loosen the connection between the second mating part 16 and the second connector 202, so that the second mating part 16 can be separated from the second connector 202, and the second connecting pipe 102 can be separated from the second connector 202.

[0181] In some specific embodiments of the present invention, the first connector 51 includes a connecting part 511 and a handle part 512. The connecting part 511 is adapted to thread the second connector 202 and the second mating part 16 together to fix the second connector 202 and the second mating part 16 together, thereby achieving stable docking of the second connector 202 and the second mating part 16, and thus realizing the conduction between the second connector 202 and the second connecting pipe 102.

[0182] The handle 512 is located on the side of the connecting part 511 facing away from the second connector 202. The extension direction of the handle 512 intersects the extension direction of the connecting part 511. The first connecting member 51 can be rotated by the handle 512, thereby enabling the connecting part 511 to engage with the second connector 202 and the second mating part 16, or disengaging the connecting part 511 from the second connector 202 and the second mating part 16, thus fixing or loosening the second connector 202 and the second mating part 16.

[0183] The first connector 51 has an operable handle 512. When the user needs to separate the second connector 202 from the second connecting pipe 102 or connect the second connector 202 to the second connecting pipe 102, he / she only needs to rotate the first connector 51 through the handle 512 without the need for other tools, which is convenient to operate.

[0184] In some embodiments, the first connector 51 further includes a clamping portion 513, which is located between the connecting portion 511 and the handle portion 512, and the diameter of the clamping portion 513 is larger than the diameter of the connecting portion 511.

[0185] The connecting part 511 is adapted to be threaded into the second connector 202, and the clamping part 513 clamps the second mating part 16 to fix the second connector 202 and the second mating part 16 together.

The first operating port is located near the first connector 51 so that the first connector 51 can be operated through the first operating port, thereby fixing or separating the first connector 201 from the first connecting tube 101, and connecting or separating the second connector 202 from the second connecting tube 102.

[0187] In some specific embodiments of this utility model, such as Figure 3 , Figure 8 As shown, the vehicle also includes a first decorative panel 61, which is detachably disposed at the first operating port to hide the position of the first operating port. On the one hand, this can improve the overall appearance of the vehicle interior, and on the other hand, it can prevent water, dust and other contaminants from polluting the first operating port.

[0188] In some embodiments of this utility model, such as Figure 9 , Figure 13 As shown, the first side plate 23 of the storage box 20 has a threaded hole 27, and the housing 40 is adapted to be fixedly connected to the first side plate 23 by a detachable second connector 52 to fix the position of the storage box 20 in the receiving cavity 401.

[0189] In some optional embodiments of this utility model, such as Figure 9 As shown, the housing 40 has a second operating port 45 that communicates with the receiving cavity 401. The second operating port 45 is located above the first side plate 23. The user can rotate the second connector 52 through the second operating port 45 to fix the housing 40 and the first side plate 23 together or loosen the housing 40 and the first side plate 23.

[0190] In some embodiments, the structure of the second connector 52 is the same as that of the first connector 51. The second connector 52 includes a connecting portion 511 and a handle portion 512. The connecting portion 511 is adapted to be threadedly connected to the housing 40 and the first side plate 23 to thread the housing 40 and the storage box 20 together.

[0191] The handle 512 is located on the side of the connecting part 511 facing away from the first side plate 23. The extension direction of the handle 512 intersects the extension direction of the connecting part 511. The second connecting member 52 can be rotated by the handle 512, thereby enabling the connecting part 511 to be connected with the housing 40 and the first side plate 23, or to disengage the connecting part 511 from the housing 40 and the first side plate 23, thereby fixing or loosening the housing 40 and the storage box 20.

[0192] The second connector 52 has an operable handle 512. When the user needs to separate the housing 40 from the first side plate 23 or needs to fix the housing 40 and the first side plate 23 together, he / she only needs to rotate the second connector 52 by the handle 512. No other tools are required, making it convenient to operate.

[0193] In some examples, the second connector 52 further includes a clamping portion 513 located between the connector 511 and the handle portion 512, the diameter of the clamping portion 513 being larger than the diameter of the connector 511.
