DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be described below through specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present utility model.

[0020] Here, it should also be noted that in order to avoid obscuring the present utility model with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.

[0021] Refer to Figures 1-4 As shown, the following technical solutions are adopted in this specific embodiment: It includes a vehicle-mounted refrigerator 1 and a sliding door assembly 2; among them, the sliding door assembly 2 includes a port frame 21, a sliding lifting guide rail 22, a lock tongue slide rail 23, a fixing bolt 24, and a sliding sealing door 25; the upper port of the vehicle-mounted refrigerator 1 is clamped and fixed with a sliding door assembly 2, and the sliding lifting guide rails 22 are integrally arranged on the left and right sides of the port frame 21, and a lock tongue slide rail 23 is fixed at the upper end of the sliding lifting guide rail 22 through a fixing bolt 24; the four-corner sliding rollers of the sliding sealing door 25 are clamped inside the sliding lifting guide rail 22, and the lock tongues on both sides of the sliding sealing door 25 are kept clamped with the lock tongue slide rail 23.

[0022] Among them, the sliding lifting guide rail 22 is composed of a front-wheel guide rail 221 and a rear-wheel guide rail 222. The front-wheel guide rail 221 and the rear-wheel guide rail 222 are arranged front and rear, and inclined lifting slopes 223 are provided at the front ends of the front-wheel guide rail 221 and the rear-wheel guide rail 222; the inclined lifting slopes 223 cooperate with the four-corner guide wheels of the sliding sealing door 25 to realize the downward pressure when the sliding sealing door 25 is closed with the surface of the port frame 21 and the backward movement and lifting when it is opened.

[0023] In addition, a sealing strip is inlaid on the lower surface of the sliding sealing door 25, and the specification and size of the sealing strip correspond to the open opening at the front end of the port frame 21; the sliding sealing door 25 internally includes an unlocking pressing member 251, a compression return spring 252, a rotating shaft 253, a linkage rotating member 254, and a telescopic spring lock tongue 255; the unlocking pressing member 251 is fixed in the middle inside the sliding sealing door 25 through a fixing member, and the tail of the unlocking pressing member 251 is connected with a compression return spring 252. The left and right sides of the unlocking pressing member 251 are movably connected with a linkage rotating member 254 through a rotating shaft 253. A telescopic spring lock tongue 255 is arranged on the outer side of the linkage rotating member 254. The two bifurcated arms of the linkage rotating member 254 are respectively connected to the middle of the unlocking pressing member 251 and the tail of the telescopic spring lock tongue 255 to realize the linkage between the unlocking pressing member 251 and the telescopic spring lock tongue 255 to complete unlocking.

[0024] The working principle of this specific embodiment is as follows: When sliding the door open, manually press the unlocking pressing member 251 backward. The unlocking pressing member 251 drives the linkage rotating member 254 to rotate inwardly by pressing, and pulls the telescopic spring lock tongue 255 backward to realize the retraction of the lock tongue to complete unlocking, so that the sliding sealing door 25 moves backward. During this process, the pulleys at the four corners of the sliding sealing door 25 are affected by the inclined lifting slope 223 to lift the sliding sealing door 25 upward, so that the sealing strip is separated from the window to reduce the friction during backward movement; when closing the door, only need to push the sliding sealing door 25 forward. The telescopic spring lock tongue 255 automatically retracts inward when being squeezed by the limit stop member to complete locking. At the same time, the sliding sealing door 25 is pressed on the port under the action of the inclined lifting slope 223 to form a squeezing seal.

[0025] After adopting the above structure, the beneficial effects of this specific embodiment are as follows: It uses a backward sliding door structure to replace the flip door and drawer structure of the traditional vehicle-mounted refrigerator. The backward sliding structure reduces the space occupied after the vehicle-mounted refrigerator is opened, and improves the convenience of opening the door; in addition, the sliding door is increased with a lifting structure, which can greatly improve the closing sealing performance and is more safe and reliable.
