Technical Field

[0001] The present invention relates to the field of portable refrigerators, and more specifically, to a vehicle-mounted refrigerator with expandable capacity. Background Art

[0002] A vehicle-mounted refrigerator is a portable refrigeration device designed specifically for the automotive environment. Its refrigeration principle is the same as that of a traditional household refrigerator, that is, it uses a compressor to drive the refrigerant cycle to achieve refrigeration, and can meet the needs of users to refrigerate food, beverages or medicines during travel, camping or daily commuting.

[0003] However, the internal space size of existing vehicle-mounted refrigerators is fixed. Sometimes there are more items to be carried during travel and sometimes less. If the internal space is too small, all items cannot be carried completely, while if the internal space is too large, it is easy to cause a large amount of power waste, which is not conducive to the rational use of the device by users. Summary of the Invention

[0004] The purpose of the present invention is to provide a vehicle-mounted refrigerator to solve the above problems.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A vehicle-mounted refrigerator, comprising: a main box body, a first installation groove is recessed inward at the bottom of one side of the main box body, and a side box body for placing a compressor is detachably installed in the first installation groove; a stabilizing plate horizontally arranged and a partition vertically arranged are fixedly connected to the inner wall of the main box body above the side box body; a box frame is arranged above the main box body, a box door that can be opened and closed is installed on the box frame, and a stabilizing member is installed between the box frame and the main box body; an expansion box is detachably installed between the main box body and the box frame, a first snap structure is arranged between the expansion box and the main box body, and a second snap structure is arranged between the expansion box and the box frame.

[0006] By setting an expansion box and the first snap structure and the second snap structure designed to cooperate with it, when there are fewer items to be refrigerated, the box frame can be directly installed on the main box body, making the internal space size relatively small, and thus the power consumption can be greatly reduced while maintaining the same temperature. When there are more items to be refrigerated, the main box body and the box frame can be separated first, then the expansion box is installed on the main box body and sealed and clamped using the first snap structure, then the box frame is installed on the expansion box and sealed and clamped using the second snap structure, and finally the stabilizing member is fixed with screws. Therefore, under the action of the stabilizing member, the main box body, the expansion box and the box frame are clamped with each other to achieve a sealing effect, thereby expanding the internal space of the device, facilitating the refrigeration of more items, and achieving the purpose of rational use.

[0007] Preferably, the first snap structure includes a first side groove provided at the top of the outer side of the main box body for the lower end of the expansion box to enter, and a plurality of first limiting blocks fixedly connected to the lower part of the inner wall of the expansion box. A first limiting groove for the upper end of the main box body to be snapped into is formed between the first limiting blocks and the expansion box.

[0008] By providing the first side groove, the main box body and the expansion box can be mutually attached and tightened, and the first limiting groove is used to increase the contact area between the two, which can improve the clamping stability and sealing performance between the two while facilitating assembly.

[0009] Preferably, the second snap structure includes a second side groove provided at the top of the outer side of the expansion box for the lower end of the box frame to enter, and a plurality of second limiting blocks fixedly connected to the lower part of the inner wall of the box frame. A second limiting groove for the upper end of the expansion box or the main box body to be snapped into is formed between the second limiting blocks and the box frame.

[0010] By providing the second side groove, the box frame and the expansion box can be mutually attached and tightened, and the second limiting groove is used to increase the contact area between the two, which can improve the clamping stability and sealing performance between the two while facilitating assembly.

[0011] Preferably, the stabilizing member includes a first tube body and a second tube body slidably connected inside the first tube body. A positioning hole is provided on the side wall of the first tube body. A positioning block is fixedly installed at the lower end inside the second tube body. Installation grooves II are provided at both ends of the positioning block. A positioning column is slidably connected in the installation groove II. A spring for pushing the positioning column to pass through the side wall of the second tube body and snap into the positioning hole is installed between the positioning column and the installation groove II.

[0012] By setting the stabilizing member to be in a retractable state, at least one set of positioning holes is provided at the upper and lower positions respectively. That is, when the expansion box needs to be used, the stabilizing member can be extended, so that the first tube body moves upward until the positioning column snaps into the upper positioning hole under the action of the spring, so as to achieve the appropriate length for the main box body, the expansion box and the box frame to be mutually attached and pressed tightly. When the expansion box is not used, the stabilizing member can be retracted, so that the first tube body moves downward until the positioning column snaps into the lower positioning hole under the action of the spring, so as to achieve the appropriate length for the main box body and the box frame to be mutually attached and pressed tightly, realizing the purpose of stable adjustment.

[0013] Preferably, handles are formed by protruding outward on both sides of the main box body.

[0014] By providing handles on the main box body, it is convenient to pick up and place the device.

[0015] Preferably, one end of the box door is rotatably connected to the box frame, and a locking component is arranged between the other end of the box door and the box frame. The locking component includes: a hand-reaching groove arranged on the box frame, and a buckling groove is arranged on the inner wall of the hand-reaching groove; a pin shaft fixedly connected to the box door, a fastener is rotatably connected to the pin shaft, a pressing part and a hook part are arranged on the fastener, and a torsion spring for driving the fastener to rotate so that the hook part is stuck into the buckling groove is installed between the pin shaft and the fastener.

[0016] By arranging the locking component, when the pressing part is pressed, the hook part can be disengaged from the buckling groove, so that the box door can be rotated and opened around the hinge position. When the box door is closed, the hook part can be driven to be stuck into the buckling groove under the action of the torsion spring, realizing the locking function and improving the sealing performance of the box door.

[0017] Preferably, a bottom frame is installed in the main box body, and a separating component for partially separating the internal space of the main box body is arranged between the bottom frame and the main box body.

[0018] By arranging the separating component, part of the space of the main box body can be separated, so that it is convenient to separately place items such as medicines that need to be placed separately, avoiding cross-contamination and affecting their use effects.

[0019] Preferably, the separating component includes a placing groove arranged in the middle of the bottom frame, two inserting plates with notches are placed in the placing groove, and horizontal slots and vertical slots for inserting the inserting plates are arranged on the inner wall of the main box body.

[0020] Since the length of the vertical slot is twice the length of the horizontal slot, by inserting the inserting plates into the vertical slot and the horizontal slot, a relatively independent space can be isolated to place items such as medicines, and the operation is simple and convenient.

[0021] Preferably, a row of arc-shaped grooves for placing canned beverage bottles are arranged on one side of the bottom frame, and a cover plate for covering the arc-shaped grooves is rotatably connected to the bottom frame.

[0022] By arranging the arc-shaped grooves, it is convenient to stack various canned beverage bottles, reducing problems such as mutual collision. Moreover, by setting a flip-up cover plate, when it is necessary to stack canned beverage bottles, the cover plate is turned up to play a role in isolation and preventing excessive movement of the beverage bottles, improving the use safety.

[0023] Preferably, when the inserting plates are placed in the placing groove and the cover plate is in the closed state, the upper surface of the bottom frame, the upper surface of one of the inserting plates, and the upper surface of the cover plate are on the same plane.

[0024] In summary, the present invention has the following beneficial effects: The present invention is provided with an expansion box and a first snap structure and a second snap structure designed to cooperate with it. When there are fewer items to be refrigerated, the box frame can be directly installed on the main box body, making the internal space relatively small, and thus significantly reducing power consumption while maintaining the same temperature. When there are more items to be refrigerated, the main box body and the box frame can be separated first, then the expansion box is installed on the main box body and sealed and clamped using the first snap structure, and then the box frame is installed on the expansion box and sealed and clamped using the second snap structure. Finally, the stabilizing member is fixed with screws. Therefore, under the action of the stabilizing member, the main box body, the expansion box, and the box frame are clamped together to achieve a sealing effect, thereby expanding the internal space of the device, facilitating the refrigeration of more items, and achieving the purpose of reasonable use.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1-3 shown, a vehicle-mounted refrigerator includes a main box body 1. A first installation groove is recessed inwardly at the bottom of one side of the main box body 1. A side box body 2 for placing a compressor is detachably installed in the first installation groove. A horizontally arranged stabilizing plate 11 and a vertically arranged partition plate 12 are fixedly connected to the inner wall of the main box body 1 above the side box body 2. A box frame 3 is arranged above the main box body 1. An openable and closable box door 31 is installed on the box frame 3. A stabilizing member 4 is installed between the box frame 3 and the main box body 1. An expansion box 5 is detachably installed between the main box body 1 and the box frame 3. A first snap structure is arranged between the expansion box 5 and the main box body 1, and a second snap structure is arranged between the expansion box 5 and the box frame 3.

[0029] It can be understood that when there are fewer items to be refrigerated, the box frame 3 can be directly installed on the main box body 1 and positioned and fixed by using the second snap structure and the stabilizing member 4, that is, only the internal space of the main box body 1 is used. At this time, the internal space size of the vehicle-mounted refrigerator is relatively small, and thus the refrigeration temperature can be reached after using less power, greatly reducing the power consumption. When there are more items to be refrigerated, the main box body 1 and the box frame 3 can be separated first, then the expansion box 5 is installed on the main box body 1 and tightly sealed by using the first snap structure, then the box frame 3 is installed on the expansion box 5 and tightly sealed by using the second snap structure, and finally the stabilizing member 4 is fixed with screws. Under the action of the stabilizing member 4, the main box body 1, the expansion box 5 and the box frame 3 are clamped with each other to achieve a sealing effect. At this time, the internal space of the vehicle-mounted refrigerator is equivalent to the sum of the internal space of the main box body 1 and the internal space of the expansion box 5, that is, the internal space of the device is expanded, which is convenient for refrigerating more items and achieves the purpose of reasonable use.

[0030] Furthermore, as Figure 2 and Figure 3 shown, the first snap structure includes a first side groove 13 arranged at the top of the outer side surface of the main box body 1 for the lower end of the expansion box 5 to enter, and a plurality of first limiting blocks 52 fixedly connected to the lower part of the inner wall of the expansion box 5. A first limiting groove for the upper end of the main box body 1 to be snapped into is formed between the first limiting blocks 52 and the expansion box 5.

[0031] It is worth mentioning that, as Figure 3 shown, the plurality of first limiting blocks 52 are evenly distributed along the edge of the expansion box 5.

[0032] It can be understood that, due to the provision of the first side groove 13, it is convenient for the lower end of the expansion box 5 to be snapped in and the sides of the two to be flush, enabling the contact between the main box body 1 and the expansion box 5 to fit and abut against each other tightly, and increasing the contact area between the two by using the first limiting groove, which can improve the clamping stability and sealing performance between the two while facilitating assembly.

[0033] Further, as Figures 2-4 shown, the second snap-fastening structure includes a second side groove 51 provided at the top of the outer side of the expansion box 5 for the lower end of the box frame 3 to enter, and a plurality of second limiting blocks 35 fixedly connected to the lower part of the inner wall of the box frame 3. A second limiting groove for the upper end of the expansion box 5 or the main box body 1 to be snapped into is formed between the second limiting blocks 35 and the box frame 3.

[0034] It is worth mentioning that, as Figure 3 and Figure 4 shown, a plurality of second limiting blocks 35 are evenly distributed along the edge of the box frame 3.

[0035] It can be understood that, due to the provision of the second side groove 51, it is convenient for the lower end of the box frame 3 to be snapped in and the sides of the two to be flush, enabling the contact between the box frame 3 and the expansion box 5 to fit and abut against each other tightly, and increasing the contact area between the two by using the second limiting groove, which can improve the clamping stability and sealing performance between the two while facilitating assembly.

[0036] Further, as Figure 3 、 Figure 7 and Figure 8 shown, the stabilizing member 4 includes a first tube body 41 and a second tube body 42 slidably connected inside the first tube body 41. A positioning hole is provided on the side wall of the first tube body 41. A positioning block 43 is fixedly installed at the lower end inside the second tube body 42. Installation grooves two are provided at both ends of the positioning block 43. A positioning column 44 is slidably connected inside the installation groove two. A spring 45 for pushing the positioning column 44 to pass through the side wall of the second tube body 42 and snap into the positioning hole is installed between the positioning column 44 and the installation groove two.

[0037] It is worth mentioning that, as Figure 7 and Figure 8 shown, the stabilizing member 4 is set to be in a retractable state, and a set of positioning holes is provided above and below the positioning hole on the first tube body 41, that is, the stabilizing member 4 has two use lengths.

[0038] It can be understood that when the expansion box 5 needs to be used, the stabilizing member 4 can be extended, so that the first tube body 41 moves upward until the positioning post 44 is snapped into the upper positioning hole under the action of the spring 45, so as to achieve the appropriate length for the main box body 1, the expansion box 5 and the box frame 3 to fit and press against each other. When the expansion box 5 is not used, the stabilizing member 4 can be retracted, so that the first tube body 41 moves downward until the positioning post 44 is snapped into the lower positioning hole under the action of the spring 45, so as to achieve the appropriate length for the main box body 1 and the box frame 3 to fit and press against each other, realizing the purpose of stable adjustment.

[0039] Further, as Figure 1 shown, handles 14 protrude outward from both sides of the main box body 1, which is convenient for picking up and placing the device.

[0040] Further, as Figure 2 、 Figure 5 and Figure 6 shown, one end of the box door 31 is rotatably connected to the box frame 3, and a locking assembly is provided between the other end of the box door 31 and the box frame 3. The locking assembly includes a reach-through groove 32 provided on the box frame 3 and a pin shaft fixedly connected to the box door 31. A buckle groove 33 is provided on the inner wall of the reach-through groove 32. A fastener 34 is rotatably connected to the pin shaft. A pressing portion 341 and a hook portion 342 are provided on the fastener 34. A torsion spring for driving the fastener 34 to rotate so that the hook portion 342 snaps into the buckle groove 33 is installed between the pin shaft and the fastener 34.

[0041] It can be understood that when the box door 31 needs to be opened, a force is applied to the pressing portion 341 to drive the pressing portion 341 to rotate and compress the torsion spring, and then synchronously drive the hook portion 342 to rotate and disengage from the buckle groove 33. At this time, the box door 31 can be rotated and opened around the hinge position. When the box door 31 needs to be closed, the above process can be repeated until the box door 31 is in full contact with the box frame 3 and then released or the box door 31 is directly pressed down. Under the action of the torsion spring, the hook portion 342 can be driven to snap into the buckle groove 33, realizing the locking function, which is simple and convenient to operate and improves the sealing performance of the box door 31.

[0042] Further, as Figure 3 shown, a bottom frame 6 is installed in the main box body 1, and a separating assembly for partially separating the internal space of the main box body 1 is provided between the bottom frame 6 and the main box body 1.

[0043] It can be understood that the separating assembly can separate part of the space of the main box body 1, so as to facilitate the separate placement of items such as medicines that need to be placed separately, and avoid cross-contamination and affect their use effects.

[0044] Further, as Figure 3As shown in the figure, the separating component includes a storage groove arranged in the middle of the bottom frame 6. Two inserted plates 61 with notches are placed in the storage groove. The inner wall of the main box body 1 is provided with a horizontal slot 15 and a vertical slot 16 for the inserted plate 61 to be inserted into.

[0045] It is worth mentioning that, as Figure 3 shown in the figure, the length of the vertical slot 16 is twice the length of the horizontal slot 15.

[0046] It can be understood that when it is necessary to place items such as medicines, take out the inserted plate 61 from the storage groove. First, insert one of the inserted plates 61 into the vertical slot 16 until it contacts the bottom frame 6. Then, items such as medicines can be placed within the range inserted by the inserted plate 61. After placing, insert the other inserted plate 61 into the horizontal slot 15 to achieve the relative independence of this area and avoid cross - contamination with other items.

[0047] Furthermore, as Figure 3 shown in the figure, one side of the bottom frame 6 is provided with a row of arc - shaped grooves for placing canned beverage bottles, and the bottom frame 6 is also rotatably connected with a cover plate 62 for covering the arc - shaped grooves.

[0048] It can be understood that the arc - shaped grooves can facilitate the stacking of various canned beverage bottles, reduce problems such as mutual collision, and a rotatable cover plate 62 is provided. When it is necessary to stack canned beverage bottles, turn up the cover plate 62, which plays a role in isolation and preventing excessive movement of the beverage bottles, improving the use safety. When the beverage bottles are not placed, it can be turned down to make the surface of the bottom frame 6 relatively flat, facilitating the placement of various items.

[0049] Furthermore, as Figure 3 shown in the figure, when the inserted plate 61 is placed in the storage groove and the cover plate 62 is in the closed state, the upper surface of the bottom frame 6, the upper surface of one of the inserted plates 61, and the upper surface of the cover plate 62 are in the same plane.

[0050] The above - mentioned is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above - mentioned embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention.
