[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] Example 1

[0027] like Figure 1-6 As shown, the utility model provides a refrigerator lock bracket device and a refrigerator, comprising a refrigerator body 1, a refrigerator upper door 2 is movably installed on the upper side of the front of the refrigerator body 1, a refrigerator lower door 4 is movably installed on the lower side of the front of the refrigerator body 1, an unlocking device 3 is fixedly installed on the front of the refrigerator upper door 2, a lock bracket 5 is fixedly installed on the front of the refrigerator body 1, the lock bracket 5 comprises a lock bracket box 51, a screw hole 52 is opened on the upper surface of the lock bracket box 51, the back of the lock bracket box 51 is threadedly connected to the front of the refrigerator body 1, a spring 55 is fixedly installed on the inner wall of the refrigerator body 1, and a lock tongue 53 is fixedly installed on the other side of the spring 55. The unlocking device 3 comprises a shell 38, a password display screen 31 is fixedly installed on the top of the front of the shell 38, a numeric keypad 32 is fixedly installed on the front of the shell 38 and at the bottom near the password display screen 31, and a fingerprint sensor 33 is fixedly installed on the bottom of the front of the shell 38.

[0028] In this embodiment, the refrigerator lock bracket device can unlock the refrigerator by password, fingerprint, finger vein, and multiple unlocking methods, which can make it more convenient to unlock the refrigerator. After the refrigerator door is closed, the lock bracket 5 will automatically lock to prevent the refrigerator door from being opened at will. After the refrigerator door is closed, the refrigerator lock bracket device is inside the refrigerator, which will not affect the overall structure of the product, maintain the beauty of the refrigerator, and make it convenient for users to use the refrigerator.

[0029] Example 2

[0030] like Figure 1-6 As shown, based on Example 1, the utility model provides a technical solution: preferably, second racks 57 are fixedly installed at both ends of the left side of the lock tongue 53, one side of the second rack 57 is engaged with a gear 58, and the other side of the gear 58 is engaged with a first rack 56, the bottom of the first rack 56 is fixedly installed on the inner wall of the refrigerator body 1, and a motor 54 is fixedly installed at the axis of the gear 58, and the motor 54 is connected to the unlocking device 3 through a signal line.

[0031] In this embodiment, the lock bracket box 51 can be fixed to the refrigerator body 1 by screws through the screw hole 52 opened on the lock bracket box 51, thereby hiding the lock body structure. The motor 54 is started to drive the gear 58 to rotate. The first rack 56 and the second rack 57 are engaged on both sides of the gear 58. The gear 58 drives the first rack 56 and the second rack 57 to move relative to each other, pulling the lock tongue 53 to move to the right, and the lock tongue 53 is pulled out from the lock hole 35, so that the protrusion 36 can be pulled out, thereby opening the refrigerator door 2.

[0032] Example 3

[0033] like Figure 1-6As shown, based on Example 1, the present invention provides a technical solution: preferably, a near-infrared lamp 34 is fixedly installed on the left side of the shell 38, a finger vein sensor 37 is fixedly installed on the inner wall of the near-infrared lamp 34 and on the left side of the shell 38, and a protrusion 36 is fixedly installed on the back side of the shell 38, and a lock hole 35 is provided on the upper surface of the protrusion 36.

[0034] In this embodiment, a password is entered through the numeric keypad 32, and the entered password can be seen on the password display screen 31. If the password entered on the numeric keypad 32 is correct, a signal will be sent to start the motor 54, thereby unlocking the refrigerator. By pressing the fingerprint of the finger on the fingerprint sensor 33, if the fingerprint matches, a signal will also be sent to start the motor 54, thereby unlocking the refrigerator. By placing the finger on the finger vein sensor 37, infrared is emitted by the near-infrared lamp 34 to eliminate epidermal interference, and the finger vein sensor 37 receives the infrared information of the blood vessels. After comparison, if it matches, a signal will be sent to start the motor 54, thereby unlocking the refrigerator. Multiple unlocking methods can meet the unlocking needs of all age groups. Biometric recognition can achieve senseless unlocking, which is convenient for daily use of the refrigerator. Finger vein recognition can be used to unlock with wet hands, which is convenient for unlocking the refrigerator when cooking.

[0035] The working principle of the refrigerator lock bracket device and the refrigerator will be specifically described below.

[0036] like Figure 1-6As shown, when the refrigerator lock bracket is used for the first time, a password, fingerprint and finger vein need to be set. After the setting is completed, the password is entered through the numeric keypad 32, and the entered password can be seen on the password display screen 31. If the password entered on the numeric keypad 32 is correct, a signal will be sent to start the motor 54, thereby unlocking the refrigerator. The fingerprint is pressed on the fingerprint sensor 33 with a finger. If the fingerprint matches, a signal will also be sent to start the motor 54, driving the gear 58 to rotate. The first rack 56 and the second rack 57 are engaged on both sides of the gear 58. The gear 58 drives the first rack 56 and the second rack 57 to move relative to each other, pulling the lock tongue 53 to move to the right, and the lock tongue 53 is pulled out from the lock hole 35, so that the protrusion 36 can be pulled out, thereby opening the refrigerator door 2, thereby unlocking the refrigerator. By placing the finger on the finger vein sensor 37, the near-infrared lamp 34 emits Infrared discharge eliminates epidermal interference, and the finger vein sensor 37 receives the infrared information of the blood vessels. If it matches after comparison, it will send a signal to start the motor 54, thereby unlocking the refrigerator. There are multiple unlocking methods to meet the unlocking needs of all age groups. Biometric recognition can achieve senseless unlocking, which is convenient for daily use of the refrigerator. The refrigerator can be unlocked with wet hands through the finger vein, which is convenient for unlocking the refrigerator when cooking. After opening the refrigerator, the motor 54 will be turned off, and the lock tongue 53 will bounce back to its original position under the action of the spring 55. When the refrigerator door is closed, the protrusion 36 will be driven by the refrigerator upper door 2 to insert into the lock bracket 5. The movement of the protrusion 36 will squeeze the lock tongue 53 and move it to the right. The spring 55 contracts. After the refrigerator upper door 2 is closed, the elastic potential energy of the spring 55 will do work on the lock tongue 53, causing the lock tongue 53 to move back to its original position through the lock hole 35, thereby jamming the protrusion 36 so that it cannot move, and locking the refrigerator upper door 2.

[0037] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
