Description

Technical Field

[0001] The invention relates to the field of vehicle refrigerator parts, in particular to a vehicle refrigerator door locking mechanism. Background Art

[0002] With the continuous development of the automobile industry and the improvement of consumer demand, car refrigerators have become an important part of the interior configuration of vehicles. However, the existing car refrigerator handle unlocking mechanism has several significant shortcomings. First of all, the humanization of operation and compliance with ergonomic principles are a major problem. Users usually need to give the refrigerator handle multiple forces and steps to successfully unlock the refrigerator and open the refrigerator door. This is very inconvenient for users to operate during the refrigerator door opening process. Secondly, the traditional unlocking mechanism mainly relies on the spring shaft to be pressed and installed in the door body. The assembly process is cumbersome and the assembly process is complicated. Against this background, it was decided to conduct in-depth research on the improvement of the refrigerator unlocking mechanism. Design a simple, efficient and easy-to-operate unlocking mechanism to improve user experience and meet market needs. Summary of the invention

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0027] like Figures 1 to 8 As shown, a door locking mechanism for a vehicle refrigerator comprises a box body 1, a door body 2 mounted on the box body 1, and a door locking device 8 arranged on the top of the door body 2, wherein the door locking device 8 comprises a door lock handle 3 arranged on the top of the door body 2 and a locking mechanism 4 rotatably mounted in the door body 2 to form a locking structure with the box body 1; an escape area 7 for escaping finger space is provided on the door body 2;

[0028] A rotating pair 5 is rotatably installed in the door body 2, one end of the rotating pair 5 is fixedly connected to the door lock handle 3, and the other end is clamped with the locking mechanism 4;

[0029] Pull the door lock handle 3 upward to rotate the rotating pair 5, and drive the locking mechanism 4 to rotate and open the door body 2 through the locking end of the rotating pair 5 and the locking mechanism 4;

[0030] The engaging part of the rotating pair 5 and the locking mechanism 4 rotates relative to the locking mechanism 4 during the swinging process to prevent motion interference. Figures 7 and 8 As shown, this is the structure of a traditional car refrigerator door lock, which is a side unlocking structure. After the handle is turned outward, it is opened from the side with a small opening range, and requires secondary auxiliary opening.

[0031] The door body 2 includes a body 21, the upper and lower end surfaces of the body 21 are provided with a panel 22 and a door liner 23, respectively, the rotation pair 5 is arranged in the body 21, and the locking mechanism 4 is arranged in the door liner 23. Figure 2As shown, a circuit board 6 for controlling the vehicle refrigerator is distributed between the panel 22 and the body 21 .

[0032] The revolving pair 5 includes a connecting portion 51 fixedly connected to the door lock catch 3 , and also includes an abutting portion 52 engaged with the locking mechanism 4 . A first rotating shaft 53 cooperating with the revolving pair 5 is disposed in the body 21 .

[0033] The connecting portion 51 has an arc-shaped cross section and extends from the door lock handle 3 to one side of the door body 2 . The abutting portion 52 is vertically distributed and the portion engaged with the locking mechanism 4 is columnar.

[0034] The locking mechanism 4 includes a lock hook 41 rotatably mounted in the door liner 23, one end of the lock hook 41 is provided with a hook portion 42 engaged with the box body 1, and the side of the hook portion 42 away from the hook portion 42 is provided with a U-shaped groove 43 engaged with the rotating pair 5, and the side of the lock hook 41 close to the U-shaped groove 43 is equipped with a reset component 44 for driving the lock hook 41 to reset, and the door liner 23 is provided with a second rotating shaft 9 that cooperates with the lock hook 41; Figure 3 As shown, the abutment 52 is clamped in the U-shaped groove 43. When the rotating pair 5 rotates around the first rotating axis 53, the abutment 52 pushes the lock hook 41 to rotate around the second rotating axis 9, so that the hook 42 is disengaged from the box body 1. During the rotation of the lock hook 41, the abutment 52 and the U-shaped groove 43 rotate relative to each other. The opening of the U-shaped groove 43 is provided with a chamfer 48 to avoid the abutment 52.

[0035] The reset component 44 is a compression spring 45, one end of which is in contact with the door liner 23 and the other end is inserted into the lock hook 41; the lock hook 41 is provided with a slot 49 that cooperates with the compression spring 45; the compression spring 45 is pressed in after the lock hook 41 is installed, replacing the traditional lock core spring that is installed first, avoiding the problem of repeated positioning when the lock hook is installed later, greatly simplifying the assembly process, improving the assembly process of the door lock, and reducing the production cost of the refrigerator; the compression spring 45 provides an extrusion force to ensure that the hook 42 cooperates with the box body 1 to prevent the door body 2 from being accidentally opened.

[0036] The door liner 23 is provided with a door liner sealing rib 46 which fits with the compression spring 45 and isolates the compression spring 45 from the box body 1 area. The door liner 23 is also provided with a box body sealing rib 47 which fits with the lock hook 41 .

[0037] The space between the inner liner sealing rib 46 and the box body sealing rib 47 is filled with a sponge strip 10; the gap between the box body 1 and the door body 2 is filled with foamed tissue. In order to ensure the rationality of assembly and the sealing effect, the box body sealing rib 47 and the door inner liner sealing rib 46 are designed.

[0038] In the present invention, when the movable door lock catch handle 3 is pulled upward by a person's hand, the door lock catch handle 3 turns upward, the rotating pair 5 rotates around the first rotating shaft 53 to overcome the spring force of the compression spring 45 and turns upward, and the lock hook 41 turns downward around the second rotating shaft 9 to complete unlocking. When the unlocking force of the door lock catch handle 3 continues to be pulled upward, the unlocking force is converted into a door opening force, and the person can pull up the door body by hand to complete the door opening action; this structure combines the unlocking force and the door opening force, and the force direction and position are consistent, which meets the basic design concept of ergonomics.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
