[0036] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] like Figures 1-9As shown, this embodiment provides an unmanned vending device, which includes a cabinet body 1, a cabinet door 2, a locking component 3, and an electronic lock 4. The cabinet body 1 includes a first side wall 11 and a second side wall 12 spaced apart along the width direction of the cabinet door 2, and has an opening 13 located between the first side wall 11 and the second side wall 12. The cabinet door 2 includes a first side 21 and a second side 22, with the first side 21 pivotally connected to the first side wall 11. The cabinet door 2 is rotatable about the pivot axis and has an open position for opening the opening 13 and a closed position for closing the opening 13. The locking component 3 is fixed to the second side 22 and located at the center along the height direction of the cabinet door 2. The electronic lock... 4. Installed on the second side wall 12, the electric lock 4 includes a first housing 41, a second housing 42, and a lock body 43. The first housing 41 is fixed to the second side wall 12 and includes a receiving cavity 412 with a mounting opening facing the first side wall 11. The second housing 42 is fastened to the mounting opening. The lock body 43 is installed in the receiving cavity 412 through the mounting opening and includes a locking tongue 431 that can extend or retract from the receiving cavity 412. When the cabinet door 2 is in the closed position and the locking tongue 431 is extended, the locking tongue 431 engages with the locking member 3 to lock the position of the cabinet door 2. When the locking tongue 431 is retracted, the cabinet door 2 can be rotated to the open position.

[0038] In this embodiment, the unmanned vending device has a locking component 3 located at the center of the cabinet door 2 along its height, and an electronic lock 4 located on the cabinet body 1. When the cabinet door 2 is in the closed position and the latch 431 of the electronic lock 4 is engaged with the locking component 3, if someone pulls on the top or bottom of the cabinet door 2, the door 2 will not deform significantly due to the engagement of the latch 431 and the locking component 3. Therefore, a large gap will not be created between the cabinet door 2 and the cabinet body 1, preventing theft of goods and improving the anti-theft performance of the unmanned vending device. Furthermore, the locking component 3 is located in the center of the cabinet door 2, making it easily noticeable to users. This avoids damage to the cabinet door 2 caused by excessive force when opening or closing it, thus preventing damage and improving its durability. In this embodiment, the electronic lock 4 of the unmanned vending device is assembled by first installing the lock body 43 into the receiving cavity 412 through the installation port, and then fastening the second housing 42 with the first housing 41. The installation is simple and convenient. In addition, the locking member 3 is located in the middle of the cabinet door 2. Even if the cabinet door 2 deforms or sinks after long-term use, the gap between the lock body 43 and the locking member 3 will not be too large, which would cause the lock to fail and ensure the reliability of the unmanned vending device.

[0039] Optionally, in this embodiment, as Figure 1 As shown, a handle 24 is provided on the second side 22 of the cabinet door 2, so that the cabinet door 2 can be opened and closed by holding the handle 24, so that the cabinet door 2 is in the open or closed position.

[0040] In this embodiment, as Figure 3 and Figure 4 As shown, the first housing 41 and the second housing 42 together form a slot 44. When the cabinet door 2 is in the closed position, the locking member 3 extends into the slot 44, and when the locking tongue 431 extends out, it engages with the locking member 3 within the slot 44. This arrangement ensures that when the cabinet door 2 is in the closed position, the locking member 3 extends into the slot 44, preventing interference between the locking member 3 and the cabinet body 1, and ensuring the normal operation of the entire unmanned vending machine.

[0041] Optionally, such as Figure 4 As shown, one of the first housing 41 and the second housing 42 is provided with a claw 421, and the other of the first housing 41 and the second housing 42 is provided with a slot 411. The claw 421 and the slot 411 engage with each other. The first housing 41 and the second housing 42 are positioned together by the claw 421 and the slot 411, making it easy to install and remove the first housing 41 and the second housing 42. In this embodiment, the first housing 41 is provided with a slot 411, and the second housing 42 is provided with a claw 421. In other embodiments, the first housing 41 is provided with a claw 421, and the second housing 42 is provided with a slot 411.

[0042] In this embodiment, as Figure 4 As shown, the second sidewall 12 includes an outer wall 121, an inner wall 122, a cabinet opening strip 123, and a foam layer (not shown in the figure). The foam layer fills the space between the outer wall 121 and the inner wall 122, and the cabinet opening strip 123 connects the ends of both the inner wall 122 and the outer wall 121. The second sidewall 12 has a groove 124 that penetrates the inner wall 122, the cabinet opening strip 123, and the foam layer. The first housing 41 is embedded in the groove 124, and the second housing 42 is fixedly connected to the first housing 41 through the inner wall 122 by a first fastener 45. By embedding the first housing 41 in the groove 124, the edge of the first housing 41 is pressed against the inner wall 122 by the foam material, stabilizing the position of the first housing 41 relative to the second sidewall 12. Furthermore, since the second housing 42 is fixedly connected to the first housing 41 through the inner wall 122 by the first fastener 45, the connection between the electric lock 4 and the cabinet 1 is more reliable. Optionally, the first fastener 45 is a bolt.

[0043] In this embodiment, as Figure 3 , Figure 4As shown, the lock body 43 is fixedly connected to the first housing 41; the second housing 42 is fixedly connected to the lock body 43 via a second fastener 46. When the cabinet door 2 is closed, the door exerts a certain impact force on the first housing 41 and the second housing 42. By fixing the second housing 42 to the lock body 43, this impact force can be prevented from detaching the second housing 42 from the first housing 41, ensuring the overall stability of the electronic lock 4. Optionally, multiple third fasteners 5 pass through through holes in the inner wall 122 and are fixedly connected to the edge of the first housing 41. Optionally, both the second fastener 46 and the third fasteners 5 are bolts.

[0044] In this embodiment, as Figures 5-7 As shown, the cabinet door 2 is equipped with a signal transmitter 23; the electronic lock 4 also includes a signal sensor 47 and a drive unit. When the cabinet door 2 is in the closed position, the signal sensor 47 corresponds to the position of the signal transmitter 23; the drive unit is connected to the latch 431 and is configured to drive the latch 431 to extend when the signal sensor 47 receives the signal emitted by the signal transmitter 23. The signal transmitter 23 emits a magnetic signal or a radio frequency signal. Specifically, when the cabinet door 2 is in the closed position, the signal transmitter 23 emits a magnetic signal or a radio frequency signal. The signal sensor 47 corresponding to the signal transmitter 23 senses the magnetic signal or radio frequency signal and generates a corresponding signal. The drive unit drives the latch 431 to extend according to the signal, so that the latch 431 engages with the locking member 3, locking the cabinet door 2 in the closed position, so that the unmanned vending device can automatically lock the position of the cabinet door 2 when it is closed. Specifically, a mounting plate 25 is fixed to the cabinet door 2, and a U-shaped locking member 3 is fixedly connected to the mounting plate 25 perpendicularly at both ends. An clearance opening 251 is provided on the mounting plate 25. A signal transmitter 23 is fixed to the side of the mounting plate 25 away from the locking member 3 and opposite to the clearance opening 251. When the cabinet door 2 is in the closed position, the signal transmitter 23 cooperates with the signal sensor 47 on the cabinet body 1. Optionally, in other embodiments, the mounting plate 25 is a magnetic plate, so that the mounting plate 25 itself forms a signal transmitter 23 that emits magnetic signals. Optionally, in this embodiment, the driving component is an electromagnet 432; in other embodiments, the driving component is a motor.

[0045] In this embodiment, as Figures 7-9As shown, the lock body 43 of the electric lock 4 includes an electromagnet 432, which includes a solenoid 401, an armature 402, and a compression spring 403. The armature 402 is inserted into the solenoid 401 and is throttle-connected to the bolt 431. The armature 402 has an extended position and a retracted position relative to the solenoid 401. When the armature 402 is in the extended position, it drives the bolt 431 to extend. When the armature 402 is in the retracted position, it drives the bolt 431 to extend. Armature 402 drives the latch 431 to retract; a compression spring 403 is fitted onto armature 402 to ensure that armature 402 always tends to move towards the extended position. When solenoid 401 is energized, it attracts armature 402, causing armature 402 to move to the retracted position against the pressure of spring 403; when solenoid 401 is de-energized, armature 402 moves to the extended position under the pressure of spring 403. The direction of movement of armature 402 is parallel to the extension and retraction direction of latch 431. By making the direction of movement of armature 402 parallel to the extension and retraction direction of latch 431, the size of lock body 43 is smaller in the direction perpendicular to the movement of latch 431, reducing the space occupied by the electronic lock 4. In this embodiment, when the cabinet door 2 is in the open position, the solenoid 401 of the electromagnet 432 is energized, causing the armature 402 to be in the retracted position, driving the latch 431 to retract. When the cabinet door 2 is in the closed position, the solenoid 401 is de-energized, and under the pressure of the compression spring 403, the armature 402 moves to the extended position, driving the latch 431 to extend and engage with the locking member 3 to lock the position of the cabinet door 2.

[0046] In this embodiment, as Figure 7 and Figure 8As shown, the lock body 43 also includes a mounting bracket 433 and an end cap 434. The length of the mounting bracket 433 extends along the extension and retraction direction of the bolt 431, and one end of the mounting bracket 433 in the length direction is provided with a first opening 406. The mounting bracket 433 is also provided with a limiting groove 407 extending along the extension and retraction direction of the bolt 431. The end cap 434 blocks the first opening 406 and is provided with a hole 408. The solenoid 401 is mounted on the mounting bracket 433. The bolt 431 is slidably inserted into the hole 408. The bolt 431 is provided with a limiting post 436, which is inserted into the limiting groove 407. When the bolt 431 extends and retracts, the limiting post 436 slides along the limiting groove 407. By engaging the bolt 431 with the hole 408 and the limiting post 436 with the limiting groove 407, the extension and retraction direction of the bolt 431 is jointly limited, ensuring that the bolt 431 reliably engages with the locking member 3 when extended. Optionally, the mounting bracket 433 includes a U-shaped frame 60 and a cover plate 50. The length of the U-shaped frame 60 extends along the extension and retraction direction of the bolt 431. The U-shaped frame 60 has a side opening, and the cover plate 50 blocks the side opening, forming a cylindrical structure together with the U-shaped frame 60 and first openings 406 at both ends of the length of the cylindrical structure. Optionally, the lock body 43 also includes a plug 437, which blocks the first opening 406 at the other end of the length of the mounting bracket 433.

[0047] In this embodiment, as Figures 7-9 As shown, the lock body 43 also includes a linkage assembly 435. The armature 402 is connected to the bolt 431 via the linkage assembly 435. The linkage assembly 435 includes a first linkage 404 and a second linkage 405. The first end of the first linkage 404 is hinged to the armature 402 via a first shaft 439. The second end of the first linkage 404 is hinged to the second linkage 405 via a second shaft 440. The second linkage 405 is rotatably mounted on the mounting bracket 433 via a pivot 438, and the pivot 438 and the second shaft 440 are parallel and spaced apart. The second linkage 405 is also connected to the bolt 431. When the armature 402 extends or retracts, the first linkage 404 drives the second linkage 405 to rotate around the axis of the pivot 438, causing the second linkage 405 to drive the bolt 431 to extend or retract. In this embodiment, by setting the linkage assembly 435, the extension stroke of the locking tongue 431 can be changed, and it can play a buffering role when the locking tongue 431 is subjected to external force impact, so as to avoid affecting the electromagnet 432.

[0048] In this embodiment, as Figure 9As shown, the latch 431 is cylindrical, and a drive groove 430 is provided on the cylinder, which runs radially through the cylinder and is connected to the circumferential surface of the cylinder. The second link 405 includes a roller 40 and a first plate 10, a second plate 20 and a third plate 30 connected in a U-shape. The roller 40 is supported by the first plate 10 and the third plate 30. The roller 40 is inserted into the drive groove 430 and can roll around its own axis. When the second link 405 rotates around the axis of the pivot 438, the roller 40 drives the latch 431 to extend and retract through the drive groove 430. By configuring the second connecting rod 405 as a U-shape to sequentially connect the first plate 10, the second plate 20, and the third plate 30, the second connecting rod 405 has high structural strength and provides reliable support for the roller 40. The insertion of the roller 40 into the drive groove 430 facilitates easy assembly and disassembly between the second connecting rod 405 and the locking tongue 431. Furthermore, when the locking tongue 431 is moved, the roller 40 can rotate around its own axis within the drive groove 430 to reduce resistance. It should be noted that in this embodiment, the limiting post 436 is perpendicularly connected to the cylinder and spaced apart from the drive groove 430. Additionally, it should be noted that both the pivot 438 and the second shaft 440 are simultaneously inserted into the first plate 10 and the third plate 30.

[0049] Optionally, such as Figures 7-9As shown, the electric lock 4 also includes a PCB board 48, a sensor 49, and a detection element 490. The PCB board 48 is installed inside the cylindrical structure and is arranged parallel to the cover plate 50. The sensor 49 is soldered to the PCB board 48. The detection element 490 is fixedly connected to one of the first connecting rod 404 and the second connecting rod 405. The detection element 490 cooperates with the sensor 49 to detect whether the latch 431 is extended. By cooperating with the sensor 49 and the detection element 490, the latch 431 is detected to retract when the cabinet door 2 is in the open position, ensuring that the locking element 3 does not collide with the latch 431 when the cabinet door 2 is closed. Optionally, an indicator light 409 is also soldered onto the PCB board 48. The indicator light 409 protrudes through a through hole in the cover plate 50 to indicate the status of the latch 431. Specifically, when the latch 431 is retracted, the indicator light 409 lights up green; when the latch 431 is extended, the indicator light 409 lights up red. Optionally, the electronic lock 4 also includes a protective cover 491. The signal sensor 47 is soldered to the PCB board 48, and the protective cover 491 covers the signal sensor 47 and is opposite to the clearance opening 501 on the cover plate 50. Optionally, a microprocessor is also soldered on the PCB board 48. The microprocessor is electrically connected to the sensor 49, the signal sensor 47, the indicator light 409, and the electromagnet 432. When the cabinet door 2 is in the open position, the microprocessor detects the signal output by the sensor 49. When it detects that the latch 431 is extended, the microprocessor controls the electromagnet 432 to drive the latch 431 to retract, and the indicator light 409 lights up green. After the cabinet door 2 is in the closed position, the signal sensor 47 cooperates with the signal transmitter 23 and sends a corresponding signal to the microprocessor. The microprocessor controls the electromagnet 432 to drive the latch 431 to extend, and the latch 431 is inserted into the locking member 3 to lock the position of the cabinet door 2.
