[0007] The locking components are provided in four groups; the four groups of locking components are respectively arranged at the upper and lower ends of the left and right sides of the inner door panel, the small balls at the upper and lower ends of the left side are coaxially arranged, and the small balls at the upper and lower ends of the right side are also coaxially arranged.

[0008] Preferably, handles are provided on both the left and right sides of the inner door panel, so that the inner door panel can be opened by pulling the handles.

[0009] Furthermore, the handle is a hidden recessed handle, which saves space and avoids interference with the outer door panel of the refrigerator.

[0010] Preferably, the diameter of the opening of the accommodating cavity for exposing the ball is smaller than the diameter of the ball, so as to ensure that the exposed part of the ball abuts against the pit and prevent the ball from completely popping out of the accommodating cavity, thereby ensuring the stability and reliability of the ball popping out and retracting.

[0011] Preferably, the elastic member is a spring, which has stable and reliable elastic function, is easy to assemble, and has low cost, and ensures the stability and reliability of the ball popping out and retracting.

[0012] A vehicle-mounted refrigerator comprises any one of the above-mentioned double-door refrigerator inner door mechanisms, wherein the second shell is fixedly arranged on the box body of the vehicle-mounted refrigerator.

[0013] Preferably, the vehicle refrigerator is a vertical vehicle refrigerator, and the inner door panel is configured to open left and right. When the inner door panel is opened from the left, the small balls at the upper and lower ends of the left side are separated from the pits, and the small balls at the upper and lower ends of the right side are pressed against the pits and serve as rotation axes; when the inner door panel is opened from the right, the small balls at the upper and lower ends of the right side are separated from the pits, and the small balls at the upper and lower ends of the left side are pressed against the pits and serve as rotation axes, which is beneficial to the overall support of the inner door panel, conforms to ergonomics, and improves user experience.

[0014] Beneficial effect: The double-door refrigerator inner door mechanism and the car refrigerator of the utility model, when the inner door panel is opened from the left, the small balls at the upper and lower ends of the left side are separated from their pits, and the small balls at the upper and lower ends of the right side are against their pits and serve as rotating shafts; when the inner door panel is opened from the right, the small balls at the upper and lower ends of the right side are separated from their pits, and the small balls at the upper and lower ends of the left side are against their pits and serve as rotating shafts, thereby realizing the left and right opening of the inner door panel, better adapting to the limited space of RVs, and matching different car models; and the setting of the locking assembly ensures that the inner door panel can be closed or opened stably, reliably and conveniently, effectively avoiding the inner door panel from shaking or making abnormal noises, which is beneficial to extending the life of the inner door mechanism of the double-door refrigerator, conforming to ergonomics, and greatly improving user experience; and the design of the locking assembly is simple and ingenious, the operation is stable and reliable, it is easy to implement, and the cost is low.

[0023] Example

[0024] like Figures 1 to 5 As shown, a double-door refrigerator inner door mechanism includes an inner door panel 1 and a locking assembly 2, wherein the locking assembly 2 includes a first shell 21, a second shell 22, an elastic member and a small ball 24, wherein the first shell 21 is provided with an accommodating cavity 211, wherein the elastic member and the small ball 24 are both arranged in the accommodating cavity 211, wherein the elastic member of the present embodiment is a spring 23, wherein the part of the small ball 24 away from the elastic member is exposed in the accommodating cavity 211, and a concave pit 221 is provided on the surface of the second shell 22; wherein the first shell 21 is fixedly arranged in the inner door panel 1 and the second shell 22 is provided with a concave pit 221 ... On the door panel 1, the second shell 22 is arranged on the side of the inner door panel 1, and the part of the ball 24 exposed in the accommodating cavity 211 can be combined with or disengaged from the pit 221 under the action of the elastic member. In this embodiment, the opening diameter of the accommodating cavity 211 for exposing the ball 24 is smaller than the diameter of the ball 24; the locking assembly 2 is provided in four groups; the four groups of locking assemblies 2 are respectively arranged at the upper and lower ends on the left and right sides of the inner door panel 1, and the balls 24 at the upper and lower ends of the left side are coaxially arranged, and the balls 24 at the upper and lower ends of the right side are also coaxially arranged.

[0025] In order to open and close the inner door panel 1 more conveniently, in this embodiment, Figures 1 to 3 As shown, handles 11 are provided on both sides of the inner door panel 1; specifically, in this embodiment, the handles 11 are hidden recessed handles 11, which save space and avoid interference with the outer door panel of the refrigerator.

[0026] A car refrigerator, such as Figures 1 to 3 As shown, it includes the double-door refrigerator inner door mechanism mentioned above in this embodiment, and the second shell 22 is fixedly arranged on the box body 3 of the vehicle refrigerator; specifically, in this embodiment, the vehicle refrigerator is a vertical vehicle refrigerator, and the inner door panel 1 is arranged to open left and right.

[0027] The installation process of the inner door mechanism of the double-door refrigerator is as follows:

[0028] First, push the left side of the inner door panel 1 toward the corresponding second housing 22. During the pushing process, the second housing 22 first squeezes the ball 24, and the ball 24 then squeezes the spring 23 until the ball 24 reaches the corresponding pit 221. The ball 24 is inserted into the pit 221 under the action of the spring 23. At this time, the balls 24 at the upper and lower ends of the left side of the inner door panel 1 press against the pit 221 and serve as a rotating shaft, completing the installation of the inner door panel 1. Similarly, the installation can also be completed from the right side of the inner door panel 1. The process is the same as above and will not be repeated.

[0029] The use process of the inner door mechanism of the double-door refrigerator is as follows:

[0030] When the inner door panel 1 is opened from the left, the balls 24 at the upper and lower ends of the left side are separated from the pits 221, and the balls 24 at the upper and lower ends of the right side are against the pits 221 and serve as rotation axes. Figure 1 As shown; when the inner door panel 1 is opened from the right, the small balls 24 at the upper and lower ends of the right side are separated from their pits 221, and the small balls 24 at the upper and lower ends of the left side are against their pits 221 and serve as rotation axes; when the small balls 24 at the upper and lower ends of the left side and the small balls 24 at the upper and lower ends of the right side are all located in the pits 221, the inner wall of the inner door panel 1 fits with the box body 3, and the inner door panel 1 is in a closed state, as shown in FIG.
