Technical Field
[0001] The utility model relates to the field of automatic vending machines, in particular to a door lock linkage structure of an automatic vending machine. Background Art
[0002] With the development of technology and the internet, the devices around us are becoming increasingly intelligent. Currently, vending machines on the market generally have electromagnetic locks installed on their doors. When restocking a vending machine, staff can use their mobile devices to open designated software or system programs, scan the code on the vending machine, and obtain verification and permission from the vending machine's backend. The electromagnetic lock on the vending machine's door will then automatically unlock under control of the backend. At this point, staff can open the vending machine's door and restock it.
[0003] Currently, most vending machines on the market sell beverages or simply packaged food. Therefore, they are typically located in crowded places like subway stations, high-speed rail stations, train stations, airports, schools, and amusement parks, where network connectivity is generally good. However, with the increasing popularity of vending machines, the variety of goods they sell has expanded, such as books, medicines, and daily necessities. Consequently, the number of practical applications for vending machines carrying these items has also increased. In addition to these locations, they are also placed in areas with poor network conditions, often resulting in the vending machine door being unable to open due to network connectivity issues.
[0004] Therefore, how to avoid the failure to open the cabinet door in time due to poor signal, which affects the user's use and the staff's replenishment work, has become an urgent problem to be solved. Utility Model Content
