It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figures 1 to 3 As shown, in one embodiment, the vehicle refrigerator 10 includes an inner liner 1 and a cooling device 2; the inner liner 1 has a storage cavity 11 for storing a target object; the cooling device 2 is connected to the inner liner 1 for cooling the inner liner 1; wherein, the cooling device 2 has a fluid channel 21, which is used to connect between the output end and the input end of the refrigerant supply system of the vehicle air conditioning assembly, that is, the two ends of the fluid channel 21 are respectively used to connect the output end and the input end of the refrigerant supply system of the vehicle air conditioning assembly, so that the refrigerant supply system can input refrigerant into the fluid channel 21 and recover the refrigerant flowing out of the fluid channel 21.

[0037] When refrigerant is introduced into fluid channel 21, it absorbs heat, thereby cooling the inner liner 1 and lowering the temperature inside storage cavity 11. The fluid channel 21 has an input end and an output end, respectively. After assembly, the input end of fluid channel 21 is connected to the output end of the refrigerant supply system, and the output end is connected to the input end of the refrigerant supply system. During operation, refrigerant flows out of the refrigerant supply system from its output end, flows into fluid channel 21 from its input end, flows out of fluid channel 21 from its output end, and then enters the refrigerant supply system from its input end.

[0038] In addition, the cooling device 2 can be an evaporator, and the refrigerant can be Freon or the like. The refrigerant can be made using existing technology.

[0039] Furthermore, the refrigerant supply system can include devices such as a compressor and a condenser. The refrigerant supply system is part of the vehicle's air conditioning assembly. The air conditioning assembly can supply refrigerant to the cooling device 2 of the vehicle refrigerator 10 and can recover the refrigerant flowing out of the cooling device 2. In this way, the vehicle refrigerator 10 does not need to have an additional refrigerant supply system, thereby reducing the size of the vehicle refrigerator 10.

[0040] Compared to refrigerators in existing vehicles (which have a refrigerant supply system that enables refrigerant supply and recovery, such as a compressor and condenser), this embodiment allows for a larger storage cavity 11 while maintaining the same refrigerator volume, thereby increasing the capacity of the vehicle-mounted refrigerator 10.

[0041] Moreover, compared with refrigerators in existing vehicles, given a fixed space in the vehicle for installing a refrigerator, the configuration of this embodiment allows for a larger size of the cooling device 2, which in turn allows for a larger cross-sectional size of the fluid channel 21, thereby improving the cooling effect.

[0042] It should be understood that introducing refrigerant into the fluid channel 21 is equivalent to introducing refrigerant into the cooling device 2, and refrigerant flowing out of the fluid channel 21 is equivalent to refrigerant flowing out of the cooling device 2.

[0043] like Figure 1 and Figure 3 As shown, in one embodiment, the cooling device 2 is disposed on the inner liner 1 and located outside the storage cavity 11; this can prevent the cooling device 2 from occupying the space of the storage cavity 11 and can prevent target objects placed in the storage space from colliding with the cooling device 2.

[0044] like Figure 2 and Figure 3As shown, in one embodiment, in order to arrange the cooling device 2 on the outside of the storage cavity 11, the cooling device 2 may be disposed on the outer surface of the inner liner 1.

[0045] In one embodiment, at least a portion of the fluid channel 21 and the storage cavity 11 are arranged at intervals along a first direction; and / or, at least a portion of the fluid channel 21 and the storage cavity 11 are arranged at intervals along a second direction; and / or, at least a portion of the cooling device 2 and the storage cavity 11 are arranged along a third direction; the first direction, the second direction, and the third direction are perpendicular to each other.

[0046] Wherein, at least a portion of the fluid channel 21 and the storage cavity 11 are arranged at intervals along the first direction, which means that at least a portion of the cooling device 2 and the storage cavity 11 are arranged at intervals along the first direction.

[0047] At least a portion of the fluid channel 21 and the storage cavity 11 are arranged at intervals along the second direction, which means that at least a portion of the cooling device 2 and the storage cavity 11 are arranged at intervals along the second direction.

[0048] At least a portion of the fluid channel 21 and the storage cavity 11 are arranged at intervals along a third direction, which means that at least a portion of the cooling device 2 and the storage cavity 11 are arranged at intervals along a third direction.

[0049] Preferably, the cooling device 2 and the storage cavity 11 can be arranged at intervals in at least two of the first, second and third directions, which can improve the cooling effect of the cooling device 2 on the storage cavity 11.

[0050] exist Figures 1 to 3 Of the directions shown, the first direction is parallel to the X-axis, the second direction is parallel to the Y-axis, and the third direction is parallel to the Z-axis.

[0051] In one embodiment, the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0052] When the vehicle refrigerator 10 is applied to a vehicle, the front-to-back direction is the same as the front-to-back direction of the vehicle, the left-to-right direction is the same as the left-to-right direction of the vehicle, and the up-and-down direction is the same as the up-and-down direction of the vehicle.

[0053] In one embodiment, the storage cavity 11 has an opening on the front surface of the inner liner 1, and / or, the storage cavity 11 has an opening on the rear surface of the inner liner 1. In use, the target object can be removed from the storage cavity 11 through the opening, or the target object can be placed into the storage cavity 11 through the opening.

[0054] Normally, the storage cavity 11 forms an opening on only one of the front and rear surfaces. Of course, in some scenarios, the storage cavity 11 forms an opening on both the front and rear surfaces.

[0055] As Figure 2 and Figure 3 shown, in an embodiment, the cooling device 2 comprises a first evaporation part 22, a second evaporation part 23 and a third evaporation part 24; the first evaporation part 22 is arranged on the left surface of the inner container 1, the second evaporation part 23 is arranged on the upper surface of the inner container 1, and the third evaporation part 24 is arranged on the right surface of the inner container 1; the fluid passage 21 comprises a first passage 211, a second passage 212 and a third passage 213 which are connected in series, the first passage 211 is located in the first evaporation part 22, the second passage 212 is located in the second evaporation part 23, and the third passage 213 is located in the third evaporation part 24; the first passage 211 and the third passage 213 are respectively connected to the output end and the input end of the refrigerant supply system.

[0056] The first passage 211, the second passage 212 and the third passage 213 are connected in series. The cross-sectional radii of the first passage 211, the second passage 212 and the third passage 213 can be the same, or the cross-sectional radii of at least two of them can be different.

[0057] When the first passage 211 is connected to the output end of the refrigerant supply system and the third passage 213 is connected to the input end of the refrigerant supply system, the refrigerant first enters the first passage 211, then flows to the second passage 212, then flows to the third passage 213, and finally flows out of the third passage 213 and returns to the refrigerant supply system. At this time, the end of the first passage 211 connected to the output end of the refrigerant supply system can be the input end of the fluid passage 21; the end of the third passage 213 connected to the input end of the refrigerant supply system can be the output end of the fluid passage 21.

[0058] When the first passage 211 is connected to the input end of the refrigerant supply system and the third passage 213 is connected to the output end of the refrigerant supply system, the refrigerant first enters the third passage 213, then flows to the second passage 212, then flows to the first passage 211, and finally flows out of the first passage 211 and returns to the refrigerant supply system. At this time, the end of the first passage 211 connected to the input end of the refrigerant supply system can be the output end of the fluid passage 21; the end of the third passage 213 connected to the output end of the refrigerant supply system can be the input end of the fluid passage 21.

[0059] In addition, in the present embodiment, the cooling device 2 can cool the upper part of the inner container 1, so that the air above the storage cavity 11 is first cooled, and the cooled gas can sink, thereby accelerating the flow field movement of the gas in the storage cavity 11, and further improving the refrigeration effect.

[0060] As Figure 1 and Figure 3As shown, in one embodiment, the vehicle refrigerator 10 further includes a heat insulation plate 3, which is disposed on the side of the cooling device 2 away from the storage cavity 11.

[0061] The heat exchange rate between the storage cavity 11 and the side of the heat insulation plate 3 away from the storage cavity 11 can be reduced by using the heat insulation plate 3. This allows the temperature inside the storage cavity 11 to be maintained for a longer period of time, thereby reducing the start-stop frequency of the refrigerant supply system, extending its service life, and reducing energy consumption. For example, this can reduce the start-stop frequency of the compressor in the refrigerant supply system, thus extending the compressor's service life.

[0062] Furthermore, the heat exchange rate between the cooling device 2 and the side of the heat insulation plate 3 away from the storage cavity 11 can be reduced by setting the heat insulation plate 3, thereby improving the cooling effect of the cooling device 2 on the storage space.

[0063] In one embodiment, the insulation panel 3 may be a VIP panel (i.e., a vacuum insulation panel) or the like.

[0064] In one embodiment, the heat insulation plate 3 may be located on the outside of the inner liner 1. Moreover, when the cooling device 2 is located on the outside of the inner liner 1, at least a portion of the cooling device 2 may be located between the heat insulation plate 3 and the inner liner 1.

[0065] like Figure 3 As shown, in one embodiment, the heat insulation plate 3 includes a first plate 31, a second plate 32, and a third plate 33. The first plate 31 is disposed on the left side of the inner liner 1, the second plate 32 is disposed above the inner liner 1, and the third plate 33 is disposed on the right side of the inner liner 1. In this case, if the cooling device 2 includes the aforementioned first evaporation section 22 and third evaporation section 24, then the first evaporation section 22 is located between the first plate 31 and the inner liner 1, the second evaporation section 23 is located between the second plate 32 and the inner liner 1, and the third evaporation section 24 is located between the third plate 33 and the inner liner 1. That is, the first plate 31 is located to the left of the first evaporation section 22, the second evaporation section 23 is located above the second plate 32, and the third plate 33 is located to the right of the third evaporation section 24.

[0066] In addition, the first plate 31 and the third plate 33 are both connected to the second plate 32. At this time, the heat insulation plate 3 has a U-shaped structure.

[0067] like Figure 1 and Figure 3 As shown, in one embodiment, the vehicle refrigerator 10 further includes a heater 4, which is disposed on the inner liner 1 for heating the inner liner 1. This allows the storage cavity 11 to have a higher temperature, thereby enabling the heating of the target object within the storage cavity 11, or maintaining a higher temperature for the target object within the storage cavity 11.

[0068] It should be understood that when heater 4 is heating, the refrigerant supply system does not supply refrigerant to cooling device 2; when the refrigerant supply system supplies refrigerant to cooling device 2, heater 4 does not heat.

[0069] In one embodiment, the heater 4 is energized to generate heat, thereby heating the inner liner 1. The heater 4 may be a thin film with a heating wire that generates heat when energized. Of course, the heater 4 may also employ other existing designs.

[0070] In one embodiment, the heater 4 covers the outer surface of the inner liner 1. This facilitates the installation and maintenance of the heater 4.

[0071] When the heater 4 and the evaporator have overlapping areas, the area where the heater 4 is stacked on the evaporator (defined as the first area) can be located on the side of the evaporator away from the inner tank 1. That is, the first area is located on the outside of the evaporator. During operation, the heat generated in the first area can be transferred to the evaporator first and then to the inner tank 1.

[0072] In addition, when the vehicle refrigerator 10 has a heat insulation plate 3, the heater 4 is located between the heat insulation plate 3 and the receiving cavity 53.

[0073] like Figure 3 As shown, in one embodiment, the heater 4 includes a first heating part 41, a second heating part 42, and a third heating part 43. The first heating part 41 is located on the left side of the inner liner 1, the second heating part 42 is located below the inner liner 1, and the third heating part 43 is located on the right side of the inner liner 1. All three heating parts (41, 42, and 43) are capable of generating heat after being energized. In this configuration, the first heating part 41 is located between the first plate 31 and the inner liner 1, i.e., the first plate 31 is located to the left of the first heating part 41; the second heating part 42 is located below the inner liner 1; and the third heating part 43 is located between the third plate 33 and the inner liner 1, i.e., the third plate 33 is located to the right of the third heating part 43.

[0074] In addition, the first plate 31, the first heating part 41, the first evaporation part 22, the third evaporation part 24, the third heating part 43 and the third plate 33 are arranged in sequence from left to right.

[0075] In addition, the left and right sides of the first heating part 41 are in contact with the first evaporation part 22 and the first plate 31, respectively, and the left and right sides of the third heating part 43 are in contact with the third evaporation part 24 and the third plate 33, respectively.

[0076] In one embodiment, the first heating part 41, the second heating part 42 and the third heating part 43 can be connected in series, and in this case, the three can be connected to form a U-shaped structure.

[0077] like Figure 1 As shown, in one embodiment, the storage cavity 11 forms an opening on the outer surface of the inner liner 1; the vehicle refrigerator 10 also includes a drawer 5, which includes a storage section 51 and a sealing section 52 connected to each other; the storage section 51 is located inside the storage cavity 11 and has a receiving cavity 53 for placing a target object; the sealing section 52 is located outside the storage cavity 11 and can be close to or away from the inner liner 1; when the sealing section 52 is away from the inner liner 1, it can drive the storage section 51 so that at least a part of the storage section 51 extends out of the storage cavity 11 from the opening, so that the receiving cavity 53 is exposed in the storage cavity 11; when the sealing section 52 is close to the inner liner 1, it can drive the storage section 51 into the storage cavity 11, and the sealing section 52 can abut against the inner liner 1 to close the opening.

[0078] The target object placed in the storage cavity 11 is actually placed in the receiving cavity 53.

[0079] In use, force can be applied to the sealing part 52 to move the sealing part 52 away from the inner liner 1, thereby moving the storage part 51 out of the storage cavity 11. This allows at least a portion of the receiving cavity 53 to be exposed in the storage cavity 11, thus enabling the opening operation of the car refrigerator 10. At this time, at least a portion of the receiving cavity 53 is exposed from the inner liner 1, that is, at least a portion of the receiving cavity 53 is located outside the inner liner 1. This allows the target object to be removed from the receiving cavity 53 or placed into the receiving cavity 53.

[0080] After the target object is picked up or placed, force can be applied to the sealing part 52 in the opposite direction to bring the sealing part 52 closer to the inner liner 1, thereby pushing the storage part 51 into the storage cavity 11. When the sealing part 52 touches the inner liner 1, the closing operation of the car refrigerator 10 can be completed. At this time, the receiving cavity 53 can be completely located in the storage cavity 11, and the sealing part 52 seals the opening.

[0081] In addition, the receiving cavity 53 has a pick-and-place opening on the outer surface of the storage section 51. A target object can be placed into the receiving cavity 53 from the pick-and-place opening, and a target object can also be removed from the receiving cavity 53 from the pick-and-place opening.

[0082] The fact that at least a portion of the receiving cavity 53 is exposed in the storage cavity 11 actually means that at least a portion of the pick-and-place port is exposed in the storage cavity 11. The fact that the receiving cavity 53 is completely located within the storage cavity 11 actually means that the pick-and-place port is completely located within the storage cavity 11.

[0083] In one embodiment, the access port is located on the upper surface of the storage section 51. Alternatively, the opening of the storage cavity 11 may be located on the rear surface of the inner liner 1.

[0084] Furthermore, when the storage cavity 11 forms openings on both the front and rear surfaces of the inner liner 1, the number of drawers 5 can be two. The opening on the front surface of the inner liner 1 is called the front opening, and the opening on the rear surface of the inner liner 1 is called the rear opening. The two drawers 5 are respectively the first drawer and the second drawer. Additionally, the storage portions 51 of both drawers 5 are located within the storage cavity 11; the sealing portion 52 of the first drawer is located at the front of the inner liner 1 to seal the front opening; the sealing portion 52 of the second drawer is located at the rear of the inner liner 1 to seal the rear opening.

[0085] like Figure 2 As shown, in one embodiment, the vehicle refrigerator 10 further includes an expansion valve 6. The output end of the expansion valve 6 is connected to the cooling device 2, and the input end of the expansion valve 6 is used to connect to the output end of the refrigerant supply system, so that the refrigerant supply system can deliver refrigerant into the fluid channel 21 through the expansion valve 6. This can improve the cooling effect on the inner liner 1.

[0086] In addition, expansion valve 6 is a thermostatic expansion valve. This reduces the noise during operation of expansion valve 6 and improves the user experience.

[0087] Of course, the expansion valve can also be an electronic expansion valve 6. It should be understood that the expansion valve 6 is an existing design.

[0088] like Figure 2 As shown, in one embodiment, the vehicle refrigerator 10 further includes an input pipe 7 and an output pipe 8. The input pipe 7 connects the expansion valve 6 and the cooling device 2, wherein the output end of the expansion valve 6 is connected to the fluid channel 21 through the input pipe 7, so that after the condensate flows through the expansion valve 6, it first enters the input pipe 7 and then enters the fluid channel 21.

[0089] The output pipe 8 connects the cooling device 2 and the refrigerant supply system. After the refrigerant flows out of the fluid channel 21, it first enters the output pipe 8 and then enters the refrigerant supply system.

[0090] When expansion valve 6 is a thermostatic expansion valve, the temperature detection end of the thermostatic expansion valve can detect the temperature of the output pipe 8 in order to control the opening degree of expansion valve 6.

[0091] Alternatively, the output pipe 8 can also be connected to the refrigerant supply system via the expansion valve 6. In this case, in addition to the pipe connecting the input pipe 7 and the refrigerant supply system (defined as the first pipe), the expansion valve 6 also has a pipe connecting the output pipe 8 and the refrigerant supply system (defined as the second pipe). The diameter of the second pipe can be larger than that of the first pipe.

[0092] In an embodiment, the vehicle-mounted refrigerator 10 further comprises a stop valve for controlling the connection and disconnection between the refrigerant supply system and the fluid channel 21. When the stop valve controls the connection between the refrigerant supply system and the fluid channel 21, the refrigerant supply system can input refrigerant into the fluid channel 21; when the stop valve controls the disconnection between the refrigerant supply system and the fluid channel 21, the refrigerant supply system cannot input refrigerant into the fluid channel 21.

[0093] The stop valve can be connected in series between the output end of the refrigerant supply system and the expansion valve 6, or the stop valve can be connected in series between the output end of the expansion valve 6 and the fluid channel 21.
