[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may be an intervening component. 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. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application.

[0023] like Figures 1-3 As shown, a magnetic unlocking device for mounting on a panel 10 includes a latch 21, a latching plate 22, a spring 24, a first pin 26, a push block 27, a second pin 28, and a suction cup 25, wherein:

[0024] The latch plate 22 is connected to the panel 10 to form a groove. The panel 10 has a limiting block built into the groove. The latch 21 is slidably disposed in the groove. The two ends of the spring 24 abut against the latch 21 and the limiting block, respectively. The first pin 26 is vertically connected to the latch plate 22. The push block 27 is slidably connected to the first pin 26 and is located between the latch plate 22 and the panel 10. The push block 27 has a first inclined platform on the side away from the latch 21. The second pin 28 is horizontally connected to the latch 21 and abuts against the inclined surface of the first inclined platform. The suction cup 25 is vertically connected to the end of the push block 27 near the panel 10 and has magnetic force. When the suction cup 25 is magnetically attracted, it drives the push block 27 to move toward the panel 10, so that the latch of the latch 21 retracts into the groove to unlock. When the magnetic force is released, the suction cup 25 achieves the latch of the latch 21 extending out of the groove to lock through the elastic reset of the spring 24.

[0025] like Figure 1 , 2 As shown, the latch plate 22 is mounted on the panel 10, which can be of any shape. The latch 21 is slidably disposed in the groove formed between the latch plate 22 and the panel 10, and moves horizontally through the adsorption of the suction cup 25 in conjunction with the spring 24 and the push block 27. The spring 24 is horizontally positioned, and the push block 27 can slide up and down along the first pin 26. The suction cup 25 is connected and fixed to the push block 27. When unlocking, the magnet is placed on the underside of the panel 10. Under the magnetic adsorption, the suction cup 25 drives the push block 27 to move downward towards the panel, thereby pushing the latch 21 to the right, causing the latch 21's latch tongue to retract into the groove and complete the unlocking. When locking, the suction cup 25 moves upward under the elastic force of the spring 24, thereby automatically resetting the latch 21 and causing the latch 21's latch tongue to extend out of the groove and complete the locking.

[0026] The magnetic unlocking device 20 can be installed individually on the panel 10, or multiple devices can be installed simultaneously (preferably symmetrically) on the panel 10 to achieve locking and unlocking functions by engaging with the latch of the latch 21.

[0027] In an embodiment, the panel 10 is further provided with a clearance groove 11 for avoiding the suction cup 25. By directly arranging the clearance space on the panel 10, the volume and weight are reduced.

[0028] In an embodiment, the magnetic unlocking device further comprises a magnet 30, which is arranged on the two sides of the panel 10 opposite to the suction cup 25.

[0029] In an embodiment, the magnet 30 is a strong magnet or an electromagnet. When the magnet 30 is a strong magnet, the strong magnet can be removed after being locked, and the unlocking is realized by adsorption when needed. When the magnet 30 is an electromagnet, the unlocking or locking can be realized by controlling the power-on state of the switch.

[0030] In an embodiment, the magnetic unlocking device further comprises a bearing 29, which is coaxially arranged on the second pin 28, and the second pin 28 abuts against the inclined surface of the first inclined table through the bearing 29. This helps to reduce the resistance when unlocking.

[0031] In an embodiment, the lock catch pressing plate 22 is fixedly connected with the panel 10 through a plurality of screws 23. Alternatively, other connection manners in the prior art, such as clamping, can also be used.

[0032] In an embodiment, the lock catch 21 is provided with a through groove, and the push block 27 is arranged in the through groove. The second pin 28 is horizontally arranged in the through groove, and the push block 27 can be limited by the through groove and abut against the second pin 28 or the bearing 29, which helps to ensure the stability of the structure.

[0033] In an embodiment, the inclined surface of the first inclined table and the inclined surface of the lock tongue have the same inclination direction.

[0034] In an embodiment, the panel 10 is a door panel. It is easily understood that the panel 10 can also be any structure.

[0035] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0036] The above embodiments only express the specific and detailed embodiments described in the application, but should not be considered as the limitation of the scope of the application. It should be noted that for ordinary skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are within the scope of the application. Therefore, the protection scope of the application should be subject to the appended claims.
