[0029] The following is further described in detail through specific implementation methods:

[0030] The figure marks in the drawings of the specification include: drawer pocket 1, lock hook fixing cover 2, torsion spring 3, lock hook 4, mounting base 5, sleeve 6, rotating shaft 7, driving member 8, lock buckle 9, action plate 10, accommodating chamber 11, cylindrical portion 12, hook body 13, rotating drum 14.

[0031] As attached Figure 1-6 As shown, this embodiment shows a drawer-type vehicle refrigerator door unlocking device, and the vehicle refrigerator includes a drawer pocket 1. Food, drinks, etc. can be placed in the drawer pocket 1.

[0032] The unlocking device includes a driving member 8, a rotating shaft 7, a lock hook 4, a torsion spring 3, a lock hook fixing cover 2, a mounting base 5 and a lock buckle 9. The lock buckle 9 is arranged on the drawer pocket 1, and the lock hook 4 is rotatably arranged on the lock hook fixing cover 2. The torsion spring 3 is arranged in the lock hook 4, and the lock hook 4 is buckled with the lock buckle 9 under the action of the torsion spring 3. One end of the rotating shaft 7 is connected to the lock hook 4, and the other end is located at one side of the output end of the driving member 8. The output end of the driving member 8 extends out to drive the rotating shaft 7 to rotate to drive the lock hook 4 to disengage from the lock buckle 9.

[0033] Specifically, the driving member 8 is an electronic push rod.

[0034] The working principle of the unlocking device is as follows: the electronic push rod is pushed out 10 mm, pushing the rotating shaft 7 to rotate clockwise, and the rotating shaft 7 drives the lock hook 4 to rotate clockwise together, and the lock hook 4 rotates and disengages from the lock buckle 9. After the lock hook 4 is separated from the lock buckle 9, the drawer pocket 1 can be pulled away from the lock buckle 9.

[0035] Among them, an action plate 10 is arranged at one end of the rotating shaft 7 close to the driving member 8, and the output end of the driving member 8 drives the rotating shaft 7 to rotate by driving the action plate 10, that is, the electronic push rod drives the rotating shaft 7 to rotate clockwise by pushing the action plate 10.

[0036] The mounting base 5 is arranged on a side of the drawer pocket 1 where the lock hook fixing cover 2 is arranged, and the mounting base 5 is provided with a receiving cavity 11 corresponding to the lock hook 4, the lock hook fixing cover 2 and the lock buckle 9. The receiving cavity 11 of the mounting base 5 is arranged to ensure that the lock hook 4, the lock hook fixing cover 2 and the lock buckle 9 have space for installation and movement.

[0037] Specifically, the lock hook 4 includes a cylindrical portion 12 and a hook body 13 disposed on the outer wall of the cylindrical portion 12. The lock hook fixing cover 2 is disposed on the side of the mounting base 5 close to the drawer pocket 1. A rotating cylinder 14 is disposed on the lock hook fixing cover 2. The cylindrical portion 12 is rotatably connected to the rotating cylinder 14. The lock hook 4 is rotatably connected to the lock hook fixing cover 2 through the cooperation between the cylindrical portion 12 and the rotating cylinder 14.

[0038] The torsion spring 3 is specifically configured as follows: one end of the torsion spring 3 is fixed on the mounting base 5, and the other end of the torsion spring 3 is fixed on the cylindrical portion 12. The torsion spring 3 is used to keep the lock hook 4 in a counterclockwise rotating motion state, so that the lock hook 4 can maintain a buckled state with the lock buckle 9.

[0039] In some embodiments, a sleeve 6 is provided on one side of the mounting base 5 close to the driving member 8, and the rotating shaft 7 passes through the sleeve 6 and is connected to the cylindrical portion 12. The sleeve 6 is provided to support the rotating shaft 7 to ensure that the rotating shaft 7 rotates normally. The sleeve 6 is fixedly connected to the mounting base 5 by screws.
