Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted refrigerators, and in particular relates to a locking structure of a vehicle-mounted refrigerator. Background Art

[0002] There are two types of car refrigerators. One is a refrigerator fixed on the car, and the other is a refrigerator that is easy to carry to the car so that it can move with the car and is convenient for users to use outdoors. Traditional car refrigerators mostly use a magnetic locking structure, but the existing locking structure has the following disadvantages:

[0003] 1. Under harsh and bumpy driving conditions, there is a risk of locking failure due to the small amount of locking between the lock hook and the drawer (3-6mm); there is a risk of the drawer being pulled open under external force;

[0004] 2. The unlocking motor needs to directly push the lock hook when unlocking, so the motor is generally placed in the direction from the front to the rear of the vehicle, occupying a part of the space and limiting the capacity inside the refrigerator;

[0005] 3. When locking, there will be sliding friction between the locking structure and the drawer, resulting in greater resistance. Utility Model Content

[0006] In order to solve the defects and shortcomings of the prior art, the purpose of the utility model is to provide a locking structure for a vehicle refrigerator which has a simple structure, a reasonable design and is easy to use. It improves the locking structure and effectively ensures that the drawer will not fail to lock and be ejected under external forces and harsh road conditions such as bumps during driving. At the same time, it reduces the space occupied by the lock so that the space for the refrigerator is more ample, increases the capacity of the refrigerator, reduces wear and improves safety.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: it includes a vehicle refrigerator drawer, a lock hook, and a locking assembly; the inner top end of the vehicle refrigerator drawer is connected to the locking assembly through the lock hook for locking and fixing; wherein the locking assembly includes an outer shell, a shock-absorbing pad, a telescopic drive motor, a movable slider, a sliding pin, a compression spring, and a locking piece; the telescopic drive motor is fixed to the upper inner half of the outer shell through the shock-absorbing pad, the telescopic shaft of the telescopic drive motor is connected to the top end of the movable slider in the lower inner half of the outer shell, the movable slider is limited and fixed by sliding pins inserted on the left and right sides, and the lower end of the sliding pin is sleeved with a compression spring, and the locking piece is movably fixed inside the reserved groove in the middle of the movable slider through a pin shaft.

[0008] Preferably, the lock hook passes through a reserved hole on the surface of the outer shell and cooperates with the locking member to hook and lock the drawer of the vehicle refrigerator.

[0009] Preferably, the locking member is of a cylindrical structure and rotates around the fixing pin as the axis.

[0010] Preferably, the locking hook is in the shape of a sideways "7".

[0011] Preferably, the telescopic drive motor drives the movable slider to move up and down along the sliding pin, realizing the separation of the locking member and the locking hook.

[0012] After adopting the above structure, the beneficial effects of the present utility model are as follows:

[0013] 1. It changes the traditional locking structure of the in-vehicle refrigerator, effectively ensuring that the drawer will not be unlocked and ejected under external forces and bumpy driving conditions.

[0014] 2. The unlocking mechanism is vertically fixed at the tail, thus releasing the space from the front of the vehicle to the rear, making the space for arranging the refrigerator more abundant and increasing the capacity of the refrigerator. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be described by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are exemplary and 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 concepts of the present utility model.

[0023] Here, it should also be noted that in order to avoid obscuring the present utility model due to 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.

[0024] See, for example Figures 1 - 4 As shown, this specific embodiment adopts the following technical solution: It includes a vehicle-mounted refrigerator drawer 1, a locking hook 2, and a locking component 3; the top end inside the vehicle-mounted refrigerator drawer 1 is connected to the locking component 3 through the locking hook 2 for locking and fixing; among them, the locking component 3 includes a housing 4, a shock pad 5, a telescopic driving motor 6, a movable slider 7, a sliding pin 8, a compression spring 9, and a locking member 10; the upper half inside the housing 4 is fixed with the telescopic driving motor 6 through the shock pad 5, the telescopic shaft of the telescopic driving motor 6 is connected to the top end of the movable slider 7 in the lower half inside the housing 4, the movable slider 7 is limited and fixed by the sliding pins 8 inserted on the left and right sides, and the lower end of the sliding pin 8 is sleeved with the compression spring 9, and the locking member 10 is movably fixed inside the reserved slot in the middle of the movable slider 7 through a pin shaft.

[0025] Among them, the locking hook 2 passes through the reserved hole on the surface of the housing 4 and cooperates with the locking member 10 for hooking to lock the pulling of the vehicle-mounted refrigerator drawer 1; the locking member 10 is a cylindrical structure and rotates around a fixed pin as the axis; the locking hook 2 is a side-down "7" - shaped structure; the telescopic driving motor 6 drives the movable slider 7 to move up and down along the sliding pin 8 to realize the separation of the locking member 10 and the locking hook 2.

[0026] The working principle of this specific embodiment is as follows: When the drawer is closed, the locking of the drawer from sliding out is restricted by the limiting effect of the locking member 10 on the locking hook 2; when opening, the telescopic driving motor 6 pushes the movable slider 7, and since the locking member 10 is fixed on the movable slider 7, it drives the locking member 10 to move downward, so that the drawer is unlocked; after the drawer is unlocked and ejected, the whole movable slider 7 is reset by the elastic force of the compression spring 9.

[0027] The present utility model changes the traditional locking structure of the vehicle-mounted refrigerator, effectively ensuring that the drawer will not be unlocked and ejected under external forces and in harsh road conditions such as driving bumps; the unlocking mechanism is vertically fixed at the tail, thereby releasing the space from the front of the vehicle to the rear, making the space for the refrigerator layout more abundant and increasing the refrigerator capacity.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.

[0029] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
