Description
Technical Field
[0001] The utility model relates to the technical field of intelligent vending cabinets, and specifically, to a special intelligent lock and a vending cabinet. Background Technique
[0002] At present, intelligent locks have been widely used in vending cabinets. The intelligent lock receives the lock control signal generated by the industrial control computer to assist the vending cabinet to complete the vending task. In this process, the intelligent lock needs to feedback the state of the lock itself and the state of the cabinet door of the vending cabinet, and the industrial control computer judges the vending link to send out the correct lock control signal. The accuracy of its feedback signal and its stability and reliability under complex working conditions determine its use cost and the safety of the goods for sale.
[0003] Traditional intelligent locks applied to vending cabinets often use optical sensors to feedback the position information of the lock tongue, and use reed switches or tactile switches to feedback the open or closed state of the cabinet door. Since the optical sensor indirectly detects the position of the lock tongue, the detection device occupies more space, thus increasing the volume of the intelligent lock. In addition, in an environment with high humidity, there are certain problems with both the optical sensor and the tactile switch: the optical sensor is easily affected by water mist and obscures the optical signal; the tactile switch is easily affected by liquefied water droplets and causes false triggering. The reed switch also has problems of poor anti-interference ability and easy aging and failure during long-term use. Therefore, the traditional intelligent lock has a large volume, and its application potential is limited under complex and harsh working conditions, such as a humid environment, and it can often only detect a single state, which increases the control difficulty of the lock. During long-term use, the lock's detection of the cabinet door has the problem of sensor aging and failure, which reduces the safety and reliability of the lock.
[0004] In view of the above-mentioned status quo in the existing technology that the intelligent lock has a large volume, can only feedback the single states of the lock tongue and the cabinet door, the cabinet door detection is easily interfered, it is difficult to work in complex environments such as humidity, and its stability decreases during long-term use, we propose a special intelligent lock and a vending cabinet.

On one side of the lock body 11 away from the lock piece 12, there is an electromagnet 112 connected to the sliding rod assembly 111. Inside the lock body 11 on one side of the sliding rod assembly 111, there is a main board 113 embedded. At a position corresponding to the main board 113 on one side of the lock body 11 close to the lock piece 12, there is an RFID window cover 114;
[0051] On the lock piece 12, there is an RFID sensing array 121 and a lock tongue hole position 122, and the lock tongue hole position 122 corresponds to the position of the sliding rod assembly 111.

[0063] On the basis of the above embodiments, in order to further isolate the interference magnetic field generated by the remaining magnetic materials, the thickness and quantity of the magnetic isolation sheet 1113 are increased according to different external environments. Exemplarily, when there are many interference magnets in the cabinet body 22 of the vending cabinet main body 2, magnetic isolation sheets 1113 are arranged on both sides of the ring magnet 1112, and the magnetic isolation sheets 1113 will be thickened.
[0064] It is understandable that Figure 8 and Figure 9 only schematically shows some components included in the slide bar assembly 111, and the actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 8 and Figure 9 . In some embodiments, the annular magnet 1112 in the slide bar assembly 111 can also be fan-shaped or semi-circular, etc.

[0068] Specifically, the joints of the main board 113, the electromagnet 112 and the lock body 11 are all treated with potting process, and no specific limitation is made here. The potting process is used to enhance the waterproof and dustproof capabilities and ensure its stable operation in various complex environments
[0069] In this embodiment, the RFID sensing array 121 is composed of multiple RFID cards 1211, the number of RFID cards 1211 is greater than or equal to two, the RFID cards 1211 are located on the side of the lock piece 12 close to the lock body 11, and the multiple RFID cards 1211 are arranged at equal intervals
[0070] The RFID card 1211 is arranged in a staggered manner with the lock tongue hole position 122 and they do not contact each other
[0071] The aperture of the lock tongue hole position 122 is larger than the outer diameter of the lock head 1111

At this time, the RFID sensing area 1132 can detect the signal of the RFID card 1211 at the open position of the cabinet door. And so on, when the cabinet door 21 is in the intermediate position, the RFID sensing area 1132 can detect the signal of the RFID card 1211 at the intermediate position of the cabinet door. In this way, multiple position detections of the cabinet door 21 are realized. In other embodiments, the RFID sensing array 121 may be composed of two or more RFID cards 1211.

In the unlocked state, the sliding rod assembly 111 retracts, and the sliding rod assembly 111 retracts into the lock body 11, realizing the release of the cabinet door 21. At this time, the sliding rod assembly 111 is away from the Hall sensor 1131. Through the above operations, the Hall sensor 1131 can confirm the state of the sliding rod assembly 111 through the strength of the magnetic signal and can feedback the signal to the main board 113 for further processing.
