[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 2 , Figure 3 , Figure 4 This utility model provides an embodiment of a smart vending machine with a motor lock that can be manually and automatically controlled to open and close the door. It includes a cabinet body 1, with cabinet doors 2 slidably connected to the upper inner side of the cabinet body 1 on both the left and right sides. A mounting bracket 3 is fixedly connected to the upper rear side of the cabinet body 1. A stepper motor driver 8 is fixedly connected to the upper middle rear side of the mounting bracket 3. A switch contactor 17 is fixedly connected to the upper rear side of the cabinet doors 2. A door-closing position sensor 12 is fixedly connected to the upper front left and right sides of the mounting bracket 3. A door-closing position sensor 2 is fixedly connected to the opposite side of the door-closing position sensor 12. An open-door position sensor 14 is fixedly connected to the upper middle front left and right sides of the mounting bracket 3. An open-door position sensor 2 is fixedly connected to the opposite side of the door-opening position sensor 14. 15. The cabinet 1 is equipped with a main control system, a remote server, and a temperature detection and control system. The cabinet 1 contains several trays, and each tray has a gravity sensor at its bottom. The upper left side of the mounting frame 3 has a motor relay 16. The upper left and right sides of the mounting frame 3 have door opening and closing assemblies for controlling the cabinet door 2. The door opening and closing assemblies include a stepper motor 4, which is fixedly connected to the upper left and right sides of the mounting frame 3. The upper output end of the stepper motor 4 is fixedly connected to a ratchet 5, and the lower output end of the stepper motor 4 is fixedly connected to a gear 6. A conveyor belt 7 is located outside the gear 6. A running sensor 9 is fixedly connected to the opposite side of the upper part of the stepper motor 4. The conveyor belt 7 is fixedly connected to the cabinet door 2, and the ratchet 5 is engaged with a pawl.

[0028] The stepper motor 4 is started by controlling the gear 6 and ratchet 5 to rotate. The status change of the pawl on the ratchet 5 is detected in real time by the operation sensor 9. If no change in the pawl status is detected within a certain period of time, the status is notified to the operator's mobile phone through the main control system, so that the operator can monitor the equipment status in real time and perform maintenance in a timely manner. The gear 6 drives the conveyor belt 7 to move, and the conveyor belt 7 drives the cabinet door 2 to move horizontally to open and close the door. During the operation of the stepper motor 4, the slow running time and fast running time are preset. After the slow running time is reached, it switches to fast running. When the switch contactor 17 presses the door position sensor 15 and the door position sensor 13, the stepper motor 4 stops rotating. At the same time, during the movement of the cabinet door 2, when the right door stop plate 18 of the cabinet door 2 contacts the other cabinet door 2, the stepper motor 4 stops rotating. This realizes the sensor sensing. The dual control system, including the baffle plate, ensures the safety of cabinet door 2 during operation and reduces equipment energy consumption. When a user selects goods, the gravity sensor under the corresponding tray detects weight changes in real time and reports them to the main control system. After selecting goods, the user can control the system to automatically close the door by clicking the close button on a mobile app; alternatively, the user can manually pull cabinet door 2 to move it in the closing direction. As cabinet door 2 moves, when the switch contactor 17 on cabinet door 2 moves away from the door position sensor 14 and the door opening position sensor 2, the power to the motor relay 16 is turned on, controlling the stepper motor 4 to move in the closing direction, thus realizing the manual triggering of the closing system. During the closing process, if the consumer wants to continue selecting goods, they only need to push cabinet door 2 in the opening direction. The cabinet door 2 encounters resistance, controlling the stepper motor 4 to rotate in the opening direction, and cabinet door 2 opens again. This prevents hand pinching and assists the consumer in opening the door to select goods again.

[0029] Reference Figure 1 , Figure 2 , Figure 4 The upper part of the cabinet door 2 is provided with a locking component for locking the cabinet door 2. The locking component includes an electromagnetic lock groove 11, which is opened on the upper part of the cabinet door 2. An angled electromagnetic lock 10 is fixedly connected to the upper part of the mounting bracket 3. A cabinet door positioning baffle 18 is fixedly connected to the rear side of the upper part of the cabinet door 2.

[0030] When the door is closed, the stepper motor 4 runs at low speed. After the low-speed operation time is reached, it switches to high speed. When the cabinet door 2 moves, the door closing position sensor 12 is pressed by the switch contactor 17 and switches to low speed until the door closing position 2 is pressed by the switch contactor 17, disconnecting the power supply to the motor relay 16 and stopping the stepper motor 4. At this time, as the door moves, the electromagnetic lock groove 11 pushes the inclined surface of the inclined electromagnetic lock 10. After the lock tongue is squeezed, it retracts briefly. After the door is closed, the spring pops the lock tongue out again and locks it into the lock groove to complete the locking, so that the cabinet door 2 is locked again. The main control system reports the door closing signal to the remote server. The remote server realizes the deduction through video and weight changes.

[0031] Working principle: The stepper motor 4 is controlled to drive the gear 6 and ratchet 5 to rotate. The status change of the pawl on the ratchet 5 is detected in real time by the operation sensor 9. If no change in the pawl status is detected within a certain period of time, the status is notified to the operator's mobile phone through the main control system, so that the operator can monitor the equipment status in real time and perform maintenance in a timely manner. The gear 6 drives the conveyor belt 7 to move, and the conveyor belt 7 drives the cabinet door 2 to move horizontally to realize the opening and closing of the door. During the operation of the stepper motor 4, the slow running time and fast running time are preset. After the slow running time is reached, it switches to fast running. When the switch contactor 17 presses the door position sensor 15 and the door position sensor 13, the stepper motor 4 stops rotating. At the same time, during the movement of the cabinet door 2, when the right door stop plate 18 of the cabinet door 2 contacts the other cabinet door 2, the stepper motor 4 stops rotating. This realizes dual control of sensor sensing and stop plate, ensuring the safety of the cabinet door 2 operation and reducing equipment energy consumption.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
