[0030] Reference Figures 1 to 5 This utility model discloses a foldable car refrigerator, comprising: a rectangular box body 100, the box body 100 including a fixed box 110 and a retractable movable box 120 connected to one side of the fixed box 110, the fixed box 110 having a refrigeration unit 200 for heat exchange with the movable box 120, the side wall of the movable box 120 having at least two folded portions 124 spaced apart along the length direction of the box body 100, the folded portions 124 being close to each other to make the movable box 120 in a shortened size state, and the folded portions 124 being far apart to make the movable box 120 in an extended size state.

[0031] The above-mentioned vehicle refrigerator's body 100 consists of a fixed box 110 and a movable box 120. The movable box 120 is stretched along the length of the body 100 to move the folded portions 124 away from each other, thereby increasing the volume of the body 100 to refrigerate more items. Conversely, the movable box 120 is contracted along the length of the body 100 to bring the folded portions 124 closer together, reducing the volume of the body 100 for easier storage or transportation. The fixed box 110 can accommodate the refrigeration unit 200, and the movable box 120's switching between its shortened and extended states does not affect or damage the refrigeration unit 200.

[0032] See Figure 1 , Figure 3 and Figure 5 In some embodiments of this utility model, the movable box 120 includes a first box segment 121, a flexible box segment 122, and a second box segment 123 connected in sequence. The first box segment 121 is connected to one side of the fixed box 110 along the length direction of the box body 100. The pleated folding portions 124 are all provided on the flexible box segment 122. When the movable box 120 is in the shortened size state, at least a portion of the first box segment 121 and the second box segment 123 overlap in the width direction of the box body 100. It can be understood that when the movable box 120 is in the extended size state, the length of the movable box 120 is equal to the sum of the lengths of the first box segment 121, the flexible box segment 122, and the second box segment 123. When the movable box 120 is in the shortened size state, the length of the movable box 120 is less than the sum of the lengths of the first box segment 121 and the second box segment 123, thereby realizing a wide range of adjustment of the size of the box body 100.

[0033] In some embodiments of this utility model, to simplify the manufacturing process and reduce costs, the first box segment 121, the flexible box segment 122, and the second box segment 123 are an integral structure made of flexible material, and the pleated folded portion 124 is directly formed on the flexible box segment 122. Preferably, the flexible material is silicone or aluminum foil. To improve thermal insulation performance, the outer wall of the movable box 120 can also be covered with thermal insulation cotton without affecting the expansion and contraction deformation of the movable box 120.

[0034] It is conceivable that in some other embodiments, the first box segment 121 and the second box segment 123 can be constructed of metal sheets, which helps the movable box 120 maintain its shape stability after multiple folding and unfolding, thus extending its service life. Additionally, in some other embodiments, the flexible box segment 122 can be replaced by a folding hinge structure, but a sealing treatment is required at the pivot point of the folding hinge to limit cold air leakage.

[0035] See Figure 3 and Figure 5In some embodiments of this utility model, the width of the first box segment 121 is greater than the width of the second box segment 123. When the movable box 120 is in the shortened size state, the first box segment 121, the flexible box segment 122, and the second box segment 123 are stacked sequentially from the outside to the inside. It can be understood that the width of the first box segment 121 being greater than the width of the second box segment 123 provides space for the flexible box segment 122 to be stored after folding, and also allows the first box segment 121 and the second box segment 123 to at least partially overlap in the width direction.

[0036] See Figure 1 and Figure 5 In some embodiments of this utility model, the fixed box 110 is provided with a first handle 130 on its side wall away from the movable box 120, and the second box segment 123 is provided with a second handle 140 on its side wall away from the fixed box 110, opposite to the first handle 130. It is understood that when a user grasps the first handle 130 and the second handle 140 with both hands, and then drags the second handle 140 away from the first handle 130, the folded portion 124 on the movable box 120 can extend to lengthen the movable box 120, thereby increasing the volume of the box 100; pushing the second handle 140 closer to the first handle 130 folds the folded portion 124 on the movable box 120 to shorten its length, thereby reducing the volume of the box 100. This structure is user-friendly and convenient.

[0037] In this embodiment, the second handle 140 is fixedly mounted on a side plate, which is adhesively fixed to the side wall of the second box section 123 away from the fixed box 110. It is conceivable that, in order to keep the movable box 120 in a shortened state, a magnetic attraction structure or a clamping structure, etc., could be configured between the side plate and the fixed box 110.

[0038] See Figure 1 and Figure 4In some embodiments of this utility model, the movable box 120 has a first cavity 125 with an upward opening. The movable box 120 is movably provided with a first cover plate 300 for opening and closing the opening of the first cavity 125. The first cover plate 300 has a first state of extending along the length direction of the box body 100 and a second state of contracting along the length direction of the box body 100. The first cover plate 300 in the first state is used to close the opening of the first cavity 125 in the extended state, and the first cover plate 300 in the second state is used to close the opening of the first cavity 125 in the shortened state. It should be noted that when the movable box 120 is in its extended state, the opening of the first cavity 125 also increases accordingly. At this time, the first cover 300 needs to switch to the first state to completely cover the opening of the first cavity 125. When the movable box 120 is in its shortened state, the opening of the first cavity 125 also decreases accordingly. At this time, the first cover 300 can switch to the second state to cover the opening of the first cavity 125, while preventing the first cover 300 from protruding significantly beyond the edge of the opening of the first cavity 125, thereby reducing the volume of the box 100 for easy storage, carrying, and transportation.

[0039] See Figure 1 and Figure 4 In some embodiments of this utility model, the first cover plate 300 includes a first plate 310 and a second plate 320 rotatably connected to the first plate 310 via a horizontal pivot. The first plate 310 and the second plate 320 rotate relative to each other until they are level to form a long flat plate, which corresponds to the first state of the first cover plate 300. The first plate 310 and the second plate 320 rotate relative to each other until they are stacked vertically to form a short flat plate, which corresponds to the second state of the first cover plate 300. The first cover plate 300 with the above structure has a simple construction, low cost, and is easy to use. Of course, in other embodiments, the first plate 310 and the second plate 320 can also be configured to slide and fit together to achieve telescopic adjustment.

[0040] See Figure 2 and Figure 3 In some embodiments of this utility model, in order to improve the utilization rate of the internal space of the housing 100, the upper part of the fixed housing 110 is provided with a second cavity 111, and the lower part of the fixed housing 110 has an installation cavity 112 separated from the first cavity 125 and the second cavity 111. The refrigeration unit 200 is disposed in the installation cavity 112. The opening of the second cavity 111 is also upward, and correspondingly, a second cover plate 400 is provided to open and close the opening of the second cavity 111.

[0041] See Figure 2In some embodiments of this utility model, the refrigeration unit 200 includes a compressor 210, a throttling element 220, a first evaporator 230, and a second evaporator 240 disposed within the mounting cavity 112. A condenser is provided on the outer wall of the housing 100. The input and output ends of the condenser are respectively connected to the compressor 210 and the throttling element 220. The first cavity 125 and the second cavity 111 are independent of each other. The first evaporator 230 abuts against the side wall of the movable housing 120 near the fixed housing 110, and the second evaporator 240 abuts against the outer bottom wall of the second cavity 111. It is understood that using the first evaporator 230 and the second evaporator 240 to exchange heat between the first cavity 125 and the second cavity 111 respectively is beneficial for a more uniform internal temperature and better cooling effect in the first cavity 125 and the second cavity 111. Using an air conditioning system as the refrigeration unit 200 results in a greater cooling capacity compared to traditional refrigeration chips.

[0042] It should be noted that the compressor 210 can be powered by connecting to the car's cigarette lighter socket or by a built-in battery. Furthermore, in some embodiments, the second cavity 111 can also be connected to the first cavity 125. In this case, a step is formed between the bottom wall of the second cavity 111 and the adjacent side wall of the first cavity 125, which facilitates further expansion of the volume.

[0043] In some embodiments of this utility model, in order to further improve the heat exchange efficiency, the interior of the housing 100 is provided with a fan that drives air to circulate through the cold end of the refrigeration unit 200, the side wall of the second cavity 111 and the side wall of the first cavity 125.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
