[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0036] As Figure 1-17 shown, the present utility model provides a flip-down type vehicle-mounted refrigerator for a motorhome with a storage bin cover, including a refrigerator body 1. A door 2 that can be opened to both left and right sides or set to be opened to either of the left and right sides is provided on the front side of the refrigerator body 1. The interior of the refrigerator body 1 has a storage bin 3. A bottom plate 6 is fixedly installed at the bottom of the storage bin 3 through the side wall of the storage bin 3. A rotating shaft seat 5 is installed on the inner side wall of the refrigerator body 1 in front of the bottom plate 6. The front end of the storage bin 3 is provided with a storage bin cover 4. The lower ends of both sides of the storage bin cover 4 are clamped with the convex seats 9 on the rotating shaft seat 5.

[0037] Specifically, the rotating shaft seat 5 is fixedly connected to the inner side wall of the refrigerator body 1 through two screws, and the convex seat 9 can be inserted into the card slots at both ends of the storage bin cover 4, and the openings of the card slots are arranged outward, so that the convex seat 9 and the card slot will not be separated when the storage bin cover 4 is turned outwards.

[0038] The bottom plate 6 can be fixed to the bottom of the storage bin 3 through various connection methods, so that the storage bin 3 can form an independent space, such as interference fit, snap connection and other methods. And the rotating shaft seat 5 is just arranged at the position of the bottom plate 6, so that the bottom plate 6 can also be locked and limited. At the same time, in order to prevent the storage bin cover 4 from turning down by itself, a magnetic attraction part 7 is arranged on the inner side of the upper end of the storage bin cover 4, which is adsorbed to the front side of the upper end of the storage bin 3.

[0039] For the convenience of installation, disassembly and structural adjustment of the door 2, as Figure 1-3 shown, an upper door installation beam 15 is provided at the upper end of the front side of the refrigerator body 1, a door installation bottom plate 37 is provided at the lower end of the front side of the refrigerator body 1, and the door 2 is connected to the upper door installation beam 15 and the door installation bottom plate 37 through a door rotating shaft 17.

[0040] In order to make the vehicle-mounted refrigerator for a motorhome in this patent meet the usage needs of various motorhomes, its appearance can be set in multiple series. For example, Figure 1-14 the ones in Figure 15 are all vehicle-mounted refrigerators of series one, Figure 16 the ones shown in Figure 17 are multiple vehicle-mounted refrigerators of series two,

[0041] the ones shown in

[0042] are multiple vehicle-mounted refrigerators of series three, Figure 1-5As shown in the figure, for the door connection and opening structure of the first embodiment of Series 1, at least one limiting protrusion 16 is provided on both sides of the lower end surface of the upper beam 15 for door installation. At a position corresponding to the limiting protrusion 16 on any side of the upper end of the door 2, a handle base 13 is installed. On the upper side of the handle base 13, a first door opening handle 10 is connected through a flipping rotating shaft 11. A first spring 12 is provided between the first door opening handle 10 and the handle base 13. A limiting groove 14 corresponding to the limiting protrusion 16 is provided on the first door opening handle 10. The first door opening handle 10 can be installed on the left or right side of the upper end of the door 2. For example, when the first door opening handle 10 is installed on the left side of the upper end of the door 2, a replacement plate 8 is provided on the right side of the lower end surface of the upper beam 15 for door installation. A hollow groove corresponding to the limiting protrusion 16 is provided on the replacement plate 8. The replacement plate 8 can block the limiting protrusion 16 to avoid affecting the use after the door 2 is opened. As the principle of opening the door, when the first door opening handle 10 is not pulled up from the outside, the first door opening handle 10 is in a horizontal state under the action of the first spring 12, and the limiting protrusion 16 is embedded in the limiting groove 14, so that the door 2 cannot be opened. When the first door opening handle 10 is pulled up and flipped outward, the limiting protrusion 16 is separated from the limiting groove 14, and then the door 2 can be opened.

[0043] If it is necessary to change the opening direction of the door 2, only the positions of the replacement plate 8, the handle base 13, and the first door opening handle 10 need to be changed, and at the same time, the position of the door rotating shaft 17 is changed.

[0044] Such as Figures 6-8As shown in the figure, for the door connection and opening structure of the second embodiment of Series 1, the door hinge 17 is installed on either the left or right side of the door 2. At the upper end of the door 2, a second door handle 18 is installed. The second door handle 18 is connected to the door 2 through a flipping hinge 11. At the center of the upper end of the door 2, a vertically movable lock block 20 is installed. Between the lower end of the lock block 20 and the door 2, a second spring 38 is installed. At the center of the lower end of the upper beam 15 of the door installation, a buckle hole 19 is provided corresponding to the lock block 20. When the inner side of the second door handle 18 is flipped downward, it presses down the lock block 20 so that the upper end of the lock block 20 is disengaged from the buckle hole 19. In this structure, if it is necessary to change the opening direction of the door 2, only the position of the door hinge 17 on the side of the door 2 needs to be changed, and no adjustment is required for other components. As the principle of opening the door, when the second door handle 18 is not pulled, the lock block 20 is not under downward pressure. Therefore, the lock block 20 is in a high position under the action of the second spring 38 and is embedded in the buckle hole 19, and the door 2 cannot be opened. When the second door handle 18 is pulled and flipped, the lock block 20 can be pressed down so that the upper end of the lock block 20 is disengaged from the buckle hole 19, and then the door 2 can be opened. To facilitate the automatic rebound and flipping reset of the second door handle 18, a number of third springs 21 are installed between the inner side of the second door handle 18 and the door 2.

[0045] As Figures 9-10 shown in the figure, for the door connection and opening structure of the third embodiment of Series 1, on both sides of the upper end of the door 2, opening grooves 39 are provided. In the opening grooves 39, a third door handle 23 and a cover plate 22 covering the opening grooves 39 are respectively installed. The third door handle 23 is connected to the opening groove 39 through a flipping hinge 11. On the lower side of the upper beam 15 of the door installation, a buckle protrusion 25 is provided corresponding to the opening groove 39. At the top of the inner side of the third door handle 23, a hook portion 24 engaged with the buckle protrusion 25 is provided. Between the lower end of the inner side of the third door handle 23 and the opening groove 39, a fourth spring 40 is installed. In this embodiment, if it is necessary to change the opening direction of the door 2, only the positions of the third door handle 23 and the cover plate 22 need to be changed, and at the same time, the position of the corresponding door hinge 17 needs to be adjusted. As the principle of opening the door, when the third door handle 23 is not subjected to an external flipping force, the third door handle 23 is in a horizontal state, and the buckle protrusion 25 is engaged with the hook portion 24, so that the door 2 cannot be opened. When the third door handle 23 is subjected to an outward flipping force, the buckle protrusion 25 is disengaged from the hook portion 24, and then the door 2 can be opened.

[0046] As Figures 11-14As shown in the figure, it is the door connection and opening structure of the fourth embodiment of Series 1. At the upper end of the front side of the refrigerator body 1, there is an upper door mounting beam 15, and at the lower end of the front side of the refrigerator body 1, there is a lower door mounting base plate 37. On both left and right side edge positions of the door 2, there are fourth door handles 26 installed. Both ends of the fourth door handle 26 are connected to the door 2 through vertically arranged turning shafts 11. On both upper sides of the upper end of the door 2, there are retractable upper bolts 28 installed, and on both lower sides of the lower end of the door 2, there are retractable lower bolts 32 installed. The lower end of the upper bolt 28 is connected to an upper driving block 29 that can move up and down, and the upper end of the lower bolt 32 is connected to a lower driving block 30. Inside the fourth door handle 26, there is a push block 35 that matches the inclined surfaces of the upper driving block 29 and the lower driving block 30. When the fourth door handle 26 rotates, the push block 35 drives the upper driving block 29 and the lower driving block 30 to move towards each other synchronously to drive the upper bolt 28 and the lower bolt 32 to extend. The extended upper bolt 28 is inserted into the corresponding socket on the upper door mounting beam 15, and the extended lower bolt 32 is inserted into the corresponding socket on the lower door mounting base plate 37. Springs connected to the door 2 are installed on both the upper bolt 28 and the lower bolt 32.

[0047] When choosing the opening direction in the door 2 installation structure of this embodiment, there is no need to adjust the position of the door handle and the position of the door rotation shaft 17. Just choose the fourth door handle 26 on the corresponding side to smoothly open the door on the corresponding side.

[0048] Specifically, when choosing the fourth door handle 26 on the left to open the door, by rotating the fourth door handle 26, the push block 35 can be moved. In this way, the push block 35 acts on the upper driving block 29 and the lower driving block 30 through the inclined surface, causing the upper driving block 29 to move downward and the lower driving block 30 to move upward. In this way, the upper bolt 28 and the lower bolt 32 can be disengaged from the corresponding sockets, and the side of the door 2 where the fourth door handle 26 is located can be opened. The fourth door handle 26 on the right does not move, and the upper bolt 28 and the lower bolt 32 on the right still remain inserted into the corresponding sockets and can be used as the door rotation shaft 17.

[0049] In order to facilitate the disengagement of the upper bolt 28 and the lower bolt 32 from the sockets and their entry into the sockets, on the front sides of both the upper door mounting beam 15 and the lower door mounting base plate 37, there are guiding grooves 27 connected to the sockets.

[0050] As Figures 15-17 shown, it can be seen that for the other three series of this patent, the installation and opening methods of the door 2 can refer to the structures of the first to fourth embodiments above. These three series only have different outer shapes, and their internal structures are also the same as those of Series 1.

[0051] In this embodiment, as Figure 18 shown, both ends of the lower side of the bottom plate 6 are connected to the inner side wall of the refrigerator cabinet 1 through L-shaped brackets 41, which improves the installation firmness.

[0052] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indication will also change accordingly.

[0053] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0054] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0055] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
