[0002] To ensure the doors remain locked during RV travel and prevent accidental opening due to vehicle vibrations, a locking mechanism is used to secure the doors. Currently used locking mechanisms can only lock a single door, and these mechanisms must be pre-installed on the door or enclosure, making installation quite complex. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic door locking mechanism to overcome the above-mentioned defects in the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An automatic door locking mechanism is provided, comprising a housing, a button on the housing, a transmission block inside the housing, a latch on the transmission block, a latch groove on the housing, and the latch being disposed in the latch groove. Pressing the button causes the latch to move inside the housing, and the latch moves further into the housing.

[0006] Preferably, the transmission block is provided with a guide member, the guide member is provided with a guide surface that is inclined away from the side where the button is located, the latch presses against the guide surface, and a reset spring is provided inside the housing, one end of the reset spring is fixedly connected to the latch, and the other end of the reset spring is fixedly connected inside the housing.

[0007] Preferably, the housing is provided with a limiting block, one side of the latch abuts against the guide surface, the other side of the latch abuts against the limiting block, and the latch slides along the extending direction of the limiting block.

[0008] Preferably, the latch has a sliding surface on the side near the button, and the sliding surface is parallel to the guide surface.

[0009] Preferably, a pressing spring is provided inside the housing, and the pressing spring and the button are arranged opposite to each other on both sides of the transmission block. One end of the pressing spring presses against the inside of the housing, and the other end of the pressing spring presses against the transmission component.

[0010] Preferably, the housing is provided with latches on both sides.

[0011] The beneficial effects of this utility model are as follows: by using a latch, it is possible to achieve automatic locking of one or more refrigerator doors. By pressing the button, the door can be opened. At the same time, after releasing the button, the door can be automatically locked after closing, ensuring the stability of the door during driving and preventing the door from opening due to vehicle vibration. The opening method is convenient, enabling the door to open and close quickly. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0020] like Figure 1-3 As shown, this utility model discloses an automatic door locking mechanism. It includes a housing 1 with a button 5, a transmission block 2 inside the housing 1, a latch 3 on the transmission block 2, and a latch groove 11 on the housing 1. The latch 3 is located within the latch groove 11. Pressing the button 5 causes the latch 3 to move within the housing 1. The lock body contains the housing 1, and the latch 3 is inserted into the lock body to connect the lock body to the door. The button 5 on the housing 1 drives the transmission block 2 to move within the housing 1, and during the movement of the transmission block 2, it drives the latch 3 to move into the housing 1, causing the latch 3 to disengage from the latch groove 11, thus separating the lock body from the door and opening the door.

[0021] A guide member 21 is provided on the transmission block 2. The guide member 21 has a guide surface 22 that is inclined away from the side where the button 5 is located. The latch 3 presses against the guide surface 22. A return spring 31 is provided inside the housing 1. One end of the return spring 31 is fixedly connected to the latch 3, and the other end of the return spring 31 is fixedly connected to the housing 1. The guide member 21 is provided on the transmission block. When the transmission block 2 moves into the housing 1, it drives the guide member 21 to move. The guide member 21 moves away from the side where the button 5 is located. During the movement of the guide member 21, the guide surface 22 on the guide member 21 moves accordingly, thereby driving the latch 3 to move into the housing 1, thereby compressing the return spring 31. At the same time, after the button 5 is released, the latch 3 can be reset under the action of the return spring 31, thereby relocking the door and preventing the door from opening due to forgetting to close it during use.

[0022] A limiting block 4 is provided on the housing 1. One side of the latch 3 presses against the guide surface 22, and the other side of the latch 3 presses against the limiting block 4. The latch 3 slides along the extension direction of the limiting block 4. The limiting block 4 is provided on the housing 1. By utilizing the interaction between the limiting block 4 and the guide surface 22, the latch 3 is prevented from disengaging during its up and down movement, thus ensuring the normal use of the latch 3.

[0023] A sliding surface 32 is provided on the side of the latch 3 near the button 5. The sliding surface 32 is parallel to the guide surface 22. The sliding surface 32 on one side of the latch 3 can guide the door to compress the latch 3 to achieve smooth closing. After the door is closed, the latch 3 slides out along the sliding surface to lock the door.

[0024] A pressing spring 12 is provided inside the housing 1. The pressing spring 12 and the button 5 are arranged opposite each other on both sides of the transmission block 2. One end of the pressing spring 12 presses against the inside of the housing 1, and the other end of the pressing spring 12 presses against the transmission component. When the button 5 is pressed, the transmission block 2 moves and compresses the pressing spring 12. When the button 5 is released, the transmission block 2 returns to its original position under the action of the pressing spring 12, realizing automatic locking and facilitating the reuse of the lock body.

[0025] Locks 3 are provided on both sides of the housing 1. The locks 3 on both sides of the housing 1 ensure greater stability during use.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
