Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerators, and in particular to a vehicle refrigerator with a locking structure. Background Technology

[0002] Chinese Patent Publication No. CN217357702U discloses a car refrigerator equipped with a locking mechanism, including a cabinet assembly, an inner liner, a driver, a push rod, a drawer, a hook platform located at the bottom of the drawer, and a swing hook. The swing hook includes a first hook body and a second hook body. When the drawer is pushed into the inner liner, it is fixed by the abutting action of the end of the second hook body against the abutting surface of the front end of the hook platform. At this time, the drawer cannot move outward toward the inner liner. When unlocking is required, the user controls the driver to start, and the driver pushes the push rod forward in the inner liner, thereby pushing the first hook body to swing forward. The forward swing of the first hook body in turn causes the end of the second hook body to swing forward, thereby causing the end of the second hook body to disengage from the abutting surface. At this time, the drawer is no longer restricted by the second hook body, and can thus move outward toward the inner liner.

[0003] The problem with the existing technology is that when the swing hook is used to cooperate with the drawer, the torsion spring will cause the swing hook to collide with the drawer when the drawer is locked. The position of the hook is only temporarily fixed after the hook body collides with the drawer, and the collision will generate noise. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a vehicle refrigerator with a locking structure, which has the advantage of good noise reduction.

[0005] The technical solution adopted by this utility model to solve the problem is:

[0006] A vehicle-mounted refrigerator with a locking structure is characterized by comprising: a front-opening body, on which a power block arranged in a front-rear direction is mounted, and the front end of the power block has a first inclined surface; a locking block is vertically slidably mounted on the bottom of the body, and the locking block has a second inclined surface slidably connected to the first inclined surface, and a return spring is connected to the locking block; a power mechanism is mounted on the body, and the power mechanism is drively connected to the power block; a drawer, and a limiting part is provided at the rear bottom end of the drawer; a first guide surface is provided on the front side of the upper end of the locking block, and a second guide surface is provided on the rear side of the lower end of the limiting part, the first guide surface and the second guide surface being able to fit together; the vehicle-mounted refrigerator has a locked state and an unlocked state; in the locked state, the locking block abuts against the front side of the limiting part; in the unlocked state, the power block moves forward and presses the locking block downward, thereby causing the locking block to disengage from the limiting part.

[0007] As a further improvement to the above technical solution, the power mechanism is an electric motor, which is installed on the outer wall of the rear end of the housing, and the rear end of the power block is installed at the output end of the electric motor.

The rear end of the mounting bracket is provided with a clearance through hole, the power block is disposed in the clearance through hole, and the locking block is disposed on the mounting bracket.

[0009] As a further improvement to the above technical solution, a slider is slidably connected to the mounting bracket, a coil spring is installed on the mounting bracket, the rear end of the coil spring is fixedly connected to the slider, an elastic body is provided on the top of the slider, and a contact protrusion is provided on the bottom of the drawer, with the elastic body abutting against the rear end of the contact protrusion.

[0010] As a further improvement to the above technical solution, the bottom of the mounting bracket is provided with a slide rail pair, which is used to connect the drawer and the mounting bracket. There are two slide rail pairs, which are respectively located on the left and right sides of the locking block.

[0011] The beneficial effects of this utility model are: even when the return spring is not compressed, the drawer can still be pushed backward, and the first guide surface is pressed down by the second guide surface to compress the return spring until the limiting part moves to the rear of the locking block, the return spring is reset, and the drawer is locked. During the locking process, no collision occurs, and the noise reduction effect is good. Attached Figure Description

[0022] Reference Figures 1 to 4 A vehicle-mounted refrigerator with a locking structure includes: a front-end open body 1, on which a power block 4 is mounted along the front-rear direction, and the front end of the power block 4 has a first inclined surface 41; a locking block 5 is vertically slidably mounted on the bottom of the body 1, and the locking block 5 has a second inclined surface 51 slidably connected to the first inclined surface 41, and a return spring 6 is connected to the locking block 5; a power mechanism (not shown) is mounted on the body 1, and the power mechanism is drivenly connected to the power block 4; a drawer 2, and a limiting part 21 is provided at the rear of the bottom end of the drawer 2; the vehicle-mounted refrigerator has a locked state and an unlocked state; in the locked state, the locking block 5 abuts against the front side of the limiting part 21; in the unlocked state, the power block 4 moves forward and presses the locking block 5 downward, thereby disengaging the locking block 5 from the limiting part 21.

[0023] Reference Figure 2The locking block 5 abuts against the front side of the limiting part 21, and the power block 4 is driven to move forward by the power mechanism. The first inclined surface 41 and the second inclined surface 51 interact, causing the locking block 5 to move downward and compress the return spring 6, thereby disengaging the locking block 5 from the limiting part 21. At this time, the user can freely pull the drawer 2.

[0024] The locking block 5 has a first guide surface 52 on its upper front side and a second guide surface 211 on its lower rear side. The first guide surface 52 and the second guide surface 211 can fit together. In the unlocked state, that is, after the second inclined surface 51 is pressed down by the first inclined surface 41, the return spring 6 is compressed, and the drawer 2 can be pulled freely. In the uncompressed state, the drawer 2 can also be pushed backward, and the return spring 6 is compressed by pressing down the first guide surface 52 by the second guide surface 211.

[0025] In a preferred embodiment, the power mechanism is a motor, which is mounted on the outer wall of the rear end of the housing 1, and the rear end of the power block 4 is mounted on the output end of the motor.

[0026] In a preferred embodiment, the housing 1 includes a mounting bracket 13, which is L-shaped and fixedly disposed inside the housing 1. The rear end of the mounting bracket 13 is provided with a clearance through hole 31, the power block 4 is disposed in the clearance through hole 31, and the locking block 5 is disposed on the mounting bracket 13.

[0027] Furthermore, a slider 9 is slidably connected to the mounting bracket 13, and a coil spring 8 is mounted on the mounting bracket 3. The rear end of the coil spring 8 is fixedly connected to the slider 9. An elastic body 91 is provided on the top of the slider 9, and a contact protrusion 22 is provided on the bottom of the drawer 2. The elastic body 91 abuts against the rear end of the contact protrusion 22. When the drawer 2 is in the unlocked state, the coil spring 8 pulls the slider 9, which pushes the contact protrusion 22 through the elastic body 91, thereby pushing the drawer 2 forward. When the drawer 2 is pushed in, the elastic force of the coil spring 8 needs to be overcome, thus playing a buffering role and preventing the limiting part 21 from impacting the locking block 5 at the moment of contact, further playing a silent role.

[0028] In a preferred embodiment, the bottom of the mounting bracket 13 is provided with a slide rail pair 7, which is used to connect the drawer 2 and the mounting bracket 13. There are two slide rail pairs 7, which are respectively located on the left and right sides of the locking block 5.

[0029] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
