[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0018] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0019] See as Figures 1-5As shown, the specific implementation adopts the following technical solution:

[0020] It includes a car refrigerator door 1, a sealing strip 2, a concealed hinge 3, a locking assembly 4, and an opening button 5;

[0021] A sealing strip 2 is provided in the middle of the inner side of the vehicle refrigerator door 1. Hidden hinges 3 are provided at the upper and lower ends of the right side of the vehicle refrigerator door 1. A latch assembly 4 is provided inside the left side of the vehicle refrigerator door 1. The latch assembly 4 is connected to the side opening button 5. The latch assembly 4 consists of a drive arm 41, a connecting front axle 42, a drive rear axle 43, a movable locking tongue 44, a first return spring 45, and a second return spring 46. The inner side of the opening button 5 is connected to the connecting front axle 42 at the upper end of the drive arm 41 through a connector 51. The drive rear axle 43 at the lower end of the drive arm 41 is connected to the middle of the inner side of the movable locking tongue 44.

[0022] The drive arm 41 has a rotating shaft fixing hole 47 in the middle. The drive arm 41 is movably connected to the inside of the vehicle refrigerator door 1 through the cooperation of the fixed shaft and the rotating shaft fixing hole 47, so that the drive arm 41 swings around the rotating shaft fixing hole 47 as the axis.

[0023] In addition, the movable locking tongue 44 is located in the middle section of the left side of the vehicle refrigerator door 1. The movable locking tongue 44 is movably connected to the inner wall bracket of the vehicle refrigerator door 1 through an outwardly expanding connecting shaft, realizing the left and right swinging structure of the movable locking tongue 44. A second return spring 46 is connected to the middle of the outer side of the movable locking tongue 44, and a first return spring 45 is connected to the middle of the inner side of the front axle 42. The first return spring 45 and the second return spring 46 work synchronously to realize the reset of the drive arm 41 and the movable locking tongue 44. The installation position of the second return spring 46 corresponds to the contact point of the drive rear axle 43 and the movable locking tongue 44.

[0024] The working principle of this specific implementation method is as follows:

[0025] Pressing the open button 5 inward causes the connecting front axle 42 to move inward. Since the drive arm 41 is fixed in the middle by a rotating shaft, when the connecting front axle 42 moves inward, the drive arm 41 and the rotating shaft form a lever that pushes the drive rear axle 43 outward. The drive rear axle 43 then pushes the movable locking tongue 44 outward to unlock. When the open button 5 is released, all components automatically reset under the action of the first reset spring 45 and the second reset spring 46. The length of the drive arm 41 is maintained according to the distance between the open button 5 and the movable locking tongue 44.
