[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] The terms "first", "second", "third", etc. in the specification and claims of this application and the drawings are only used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. Reference to "embodiments" herein means that the specific features, structures or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0030] Reference Figure 1 The embodiment of the present invention provides a magnetically coded encrypted electric bolt lock, comprising: a lock body 1, a lock plate 2 and a control module A.

[0031] Reference Figure 1In the embodiment of the present application, the lock body 1 is installed on the cabinet door (not shown), and the lock plate 2 is installed on the cabinet (not shown). It can be understood that the lock body 1 can be installed on the cabinet, and the lock plate 2 can be installed on the cabinet door. In the embodiment of the present application, the lock plate 2 has a base 21, and the base 21 is provided with N (N≥2) induction magnets 22 and a first matching structure 23. The induction magnet 22 is used to generate a magnetic code. In this embodiment, four induction magnets 22 are taken as an example, and a set of 4-bit magnetic codes can be generated. Optionally, the induction magnets 22 include but are not limited to neodymium magnets, and each induction magnet has a south pole and a north pole.

[0032] Reference Figure 1 In the embodiment of the present application, the lock body 1 has a main body 11 and a second matching structure 12 disposed on the main body 11, and the first matching structure 23 cooperates with the second matching structure 12 to achieve locking. Optionally, in the embodiment of the present application, the first matching structure 23 is a through hole, the second matching structure 12 is a lock tongue, and the second matching structure 12 extends from the main body 11 to the second matching structure 12. It is understandable that the first matching structure 23 can also be a lock tongue, and the second matching structure 12 can also be a through hole. Among them, the second matching structure 12 is located on the side of the main body 11 close to the second matching structure 12.

[0033] Reference Figure 1 In the embodiment of the present application, the control module A is disposed in the lock body 1, connected to the lock body 1 (specifically connected to the second matching structure 12), and is used to control the second matching structure 12 of the lock body 1 to achieve locking of the first matching structure 23 and the second matching structure 12. It is understandable that the control module A can also be connected to the lock plate 2 (specifically connected to the first matching structure 23), and the first matching structure 23 is controlled to achieve locking of the first matching structure 23 and the second matching structure 12.

[0034] Reference Figure 1 In the embodiment of the present application, the control module A includes a controller 3 and N (N≥2) Hall sensors 4, wherein the controller 3 is electrically connected to the Hall sensors 4.

[0035] Reference Figure 1 In the embodiment of the present application, the Hall sensor 4 is used to detect the magnetic signal generated by the induction magnet 22. The number of the Hall sensors 4 is the same as the number of the induction magnets 22, and each Hall sensor 4 is arranged corresponding to one induction magnet 22 in the mechanical structure to ensure a one-to-one correspondence between the induction magnet 22 and the Hall sensor 4, that is, the Hall sensor 4 at each position is aligned with the lock induction magnet 22 to ensure the correct transmission of data (signals). In the embodiment of the present application, the Hall sensor 4 is installed on the controller 3, and the controller 3 is located on the side of the main body 11 away from the first matching structure 23.

[0036] In the embodiment of the present application, the controller 3 stores a preset magnetic code, which is pre-stored and uniquely set, and is the same as the magnetic code that can be generated by the induction magnet 22. The controller 3 includes but is not limited to any one or more processor chips including MCU, FPGA, CPLD, DSP, ARM, etc.

[0037] Reference Figure 1 , the specific working process of the present invention is described in detail below:

[0038] The Hall sensor 4 detects the surrounding magnetic field strength. When it detects that the cabinet and the cabinet door are close, the Hall sensor 4 senses the magnetic code of the induction magnet 22 and transmits it to the controller 3 (when the electrical signal exceeds the set threshold, the north (south) pole is output, and when the electrical signal is less than the set threshold, the south (north) pole is output). The controller 3 compares the magnetic codes transmitted by the four Hall sensors 4 with the data stored in the controller 3 (preset magnetic codes). When the comparison results are the same, the controller 3 will generate a lock signal to control the lock body 1 to perform the lock operation (lock), and when the comparison results are different, the lock body 1 does not perform the lock operation and remains unlocked. When locking, the lock tongue extends to the through hole to lock the door.

[0039] The embodiment of the present application further provides an automatic vending device, comprising the above-mentioned magnetically coded encrypted electric bolt lock, and the above-mentioned cabinet body and cabinet door.

[0040] The specific application scenario is as follows: a QR code is attached to one side of the cabinet of the vending machine. When the user pays by scanning the QR code, the background server of the vending machine can uniquely determine the user information and control the vending machine to unlock. At this time, the controller 3 performs the unlocking operation. When the user opens the door, selects the product, and closes the door to settle the bill, the magnetic code is generated by the induction magnet 22 due to the setting of the above-mentioned magnetic code encrypted electric bolt lock. The Hall sensor 4 transmits it to the controller 3 and compares it with the stored preset magnetic code. Only when it is correct will the lock signal be generated. The controller 3 will feedback the door state according to whether there is an unlock signal, so as to determine whether the magnetic code is correct, effectively preventing users from taking advantage of the loopholes of the existing locks to cause false door closing, improving safety, and effectively avoiding economic losses to merchants.

[0041] like Figure 2 As shown, the embodiment of the present application also provides a control method, which is applied to the above-mentioned magnetically coded encrypted electric lock, comprising:

[0042] When the lock plate is close to the lock body, the magnetic code is obtained;

[0043] According to the comparison result between the magnetic code and the preset magnetic code, one of the lock plate and the lock body is controlled to achieve locking between the lock plate and the lock body.

[0044] Optionally, when the magnetic code is the same as the preset magnetic code, one of the lock plate and the lock body is controlled.

[0045] The present application also provides a device, including:

[0046] at least one processor;

[0047] At least one memory for storing at least one program;
