Description

Technical Field

[0001] The utility model relates to an unmanned vending machine delivery door based on Internet of Things control, belonging to the technical field of unmanned vending machines. Background Art

[0002] With the current convergence of smart retail and IoT technologies, it is essential to leverage IoT technology to achieve remote monitoring, intelligent control, data analysis, and security protection for vending machine doors. By combining wireless communication technologies (such as Wi-Fi, Bluetooth, and LoRa), sensor technologies (such as photoelectric sensors and distance sensors), cloud computing and big data analysis, as well as advanced encryption algorithms and authentication mechanisms, an efficient, secure, and intelligent vending machine management system can be constructed.

[0003] Currently, the delivery door of an unmanned vending machine is opened and closed using an electromagnetic lock. Once the customer completes payment, the system automatically unlocks the door, allowing the customer to open and remove the item. Traditional technologies use an electric motor and gear drive system to control the opening and closing of the delivery door. Other technologies utilize deadweight combined with a magnetic lock to magnetically close the pickup door, while others utilize deadweight to close the door, allowing it to be opened freely without a lock.

[0032] In this embodiment, a protrusion 11 is formed on one side of the door opening 10 of the fixed mounting plate 1, and one side of the door body 2 is hinged through the damping hinge 3 and the position of the protrusion 11 on the fixed mounting plate 1; a sealing strip 12 is provided on the edge of the door opening 10, and the sealing strip 12 is fixed to the side of the fixed mounting plate 1.

[0033] See also Figure 1 Specifically, the raised portion 11 can raise the installation position of the damping hinge 3 by a certain distance, thereby facilitating the installation of the sealing strip 12 between the door body 2 and the door opening 10, thereby improving the sealing effect of the door body 2 when it is closed.

[0034] Among them, the damping hinge 3 enables the door body 2 to slowly close by relying on its own weight and built-in mechanical structure without the need for any external force to directly drive it, effectively reducing energy consumption and enhancing the smoothness of the user experience.

[0035] In this embodiment, both the first and second sensors 7, 9 are through-beam photoelectric sensors. When the second sensor 9 senses the sensor paddle 8 for a specified period of time, for example, two minutes, it controls the hook drive assembly 4 to close the lock. The hook body 5 rotates in the opposite direction until the first sensor 7 senses the hook body 5, stopping rotation. At this point, the door body 2 returns to its initial state.

[0036] In this embodiment, the lock hook drive assembly 4 includes a drive motor 13 and a motor mounting plate 14; the motor mounting plate 14 is fixedly connected to the door body 2, the drive motor 13 is connected to the motor mounting plate 14, and the lock hook body 5 is connected to the driving end of the drive motor 13; the lock hook body 5 includes an eccentric mounting portion 15, a lock hook portion 16 is formed on one side of the eccentric mounting portion 15, and a sensing portion 17 is formed on the other side of the eccentric mounting portion 15; the second sensing sensor 9 is used to control the operating state of the drive motor 13 by sensing the sensing portion 17.

When the lock hook portion 16 of the lock hook body 5 and the lock buckle body 6 are locked in a locked state, the sensing portion 17 of the lock hook body 5 can be sensed by the second sensing sensor 9. At this time, the driving motor 13 is controlled to stop running and the lock hook portion 16 of the lock hook body 5 stops rotating.

[0038] In this embodiment, the lock hook portion 16 is formed with a slope 18 to engage with the lock body 6.
