[0002] Car refrigerators are used in RVs to preserve food and other items at low temperatures. Car refrigerators are the continuation of home refrigerators. Because their usage scenarios are completely different from those of home refrigerators, the following technical problems may arise. For example, car refrigerators have higher energy-saving requirements due to limited outdoor power supply, and car refrigerators have high stability requirements as the RV bumps. Existing car refrigerators achieve energy saving by setting inner doors inside the outer doors to better seal the freezer and / or refrigerator compartment. However, what kind of connection structure is simple, reliable and stable to fix the inner door, and how to facilitate the opening and closing of the inner door are technical problems that need to be solved urgently, which is of great significance to the field of car refrigerator technology. Utility Model Content

[0003] In order to solve the problems in the prior art of how to simply and reliably fix the inner door of a vehicle refrigerator and facilitate its opening and closing, the utility model provides a vehicle refrigerator inner door assembly, a vehicle refrigerator and a motorhome.

[0031] Specifically, in this embodiment, Figure 4 As shown, the second connecting member 22 also includes a spring 223 and a spring cavity 224, and the spring cavity 224 is connected to the receiving groove 221 through a through hole 225. The spring 223 and the locking element 222 are both arranged in the spring cavity 224, and one end of the locking element 222 slides through the through hole 225 and extends into the receiving groove 221. When the first connecting member 21 enters the receiving groove 221, the locking element 222 is pushed into the spring cavity 224. When the first connecting member 21 is engaged with the receiving groove 221, one end of the locking element 222 is re-entered into the receiving groove 221 under the action of the spring 223 to limit the first connecting member 21 in the receiving groove 221, so as to ensure that the locking element 222 is movably arranged in the receiving groove 221. When the first connecting member 21 is engaged with the receiving groove 221, When engaging with the receiving groove 221, the first connecting member 21 is limited in the receiving groove 221 by the locking element 222, that is, the locking element 222 engages and disengages with the first connecting member 21 and the receiving groove 221; further, in the present embodiment, the locking element 222 is provided with a groove for accommodating the spring 223 at one end away from the first connecting member 21, and the locking element 222 is spherical at one end close to the first connecting member 21, so as to reduce the friction between the first connecting member 21 and the locking element 222, and facilitate the smooth engagement and disengagement of the first connecting member 21 and the receiving groove 221; further, in the present embodiment, the shell of the spring cavity 224 is an injection molded part, the locking element 222 is an injection molded part, and the first connecting member 21 is an injection molded part, which is easy to process and manufacture and has a low cost.

[0032] A vehicle refrigerator comprises the above-mentioned vehicle refrigerator inner door assembly, wherein the inner door 1 is used to close the compartment of the vehicle refrigerator, a sealing ring 3 is provided between the inner door 1 and the compartment of the present embodiment, the compartment of the present embodiment is a refrigerator compartment or a freezer compartment, and an outer door is also provided outside the inner door 1.

[0033] A recreational vehicle comprises the above-mentioned on-vehicle refrigerator.

[0034] The working principle of a vehicle refrigerator inner door assembly is as follows:

[0035] The process of opening the door to the left is as follows: first, hold the door handle 11 on the left side and pull the inner door 1 outwards. When the inner door 1 drives the second connecting member 22 to move outwards, the pin shaft 211 pushes the locking element 222 of the second connecting member 22 into the spring cavity 224 to unlock it. At this time, the inner door 1 is continuously pulled outwards to disengage the pin shaft 211 from the receiving groove 221. At the same time, the locking element 222 is reset to the locked state under the action of the spring 223. Then, a smaller force is used to continue to pull the inner door 1 outwards to complete the left opening of the inner door 1.

[0036] The process of closing the door to the left is as follows: first, the inner door 1 is rotated toward the refrigerator housing, and the inner door 1 drives the second connecting member 22 on the left side to move inward until the pin shaft 211 pushes the locking element 222 of the second connecting member 22 into the spring cavity 224 to unlock it. When the pin shaft 211 enters the receiving groove 221 and is in place, the locking element 222 is reset to the locked state under the action of the spring 223, and the inner door 1 is closed to the left. Figure 1 and Figure 2 shown.

[0037] The process of opening the door to the right is as follows: The process is the same as the process of opening the door to the left, except that the left side becomes the right side, so I will not repeat it;

[0038] The process of closing the door to the right is as follows: The process is the same as the process of closing the door to the left, except that the left side becomes the right side. Figure 1 and Figure 2 As shown, no further details are given.

[0039] Example 2.

[0040] like Figure 5 and Figure 6 As shown, in this embodiment, the difference from embodiment 1 is that the locking element 222 is a magnet, the material of the first connecting member 21 is a ferromagnetic metal, and the ferromagnetic metal of this embodiment is iron, and the first connecting member 21 is fixedly installed on the inner door, and the coupling member is located on the side of the receiving groove 221. In the closed state, the locking element 222 and the first connecting member 21 are attracted to ensure that the inner door is firm and does not shake; during the door opening process, there is a certain attraction between the first connecting member 21 as the door axis and the corresponding magnet, so that there is a certain damping during the door opening process, improving the door opening feel to optimize the user experience.

[0041] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
