Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example:

Please refer to FIG. 1 to FIG. 4, the present utility model provides a technical solution:

An anti-theft takeaway box, comprising a box body 1, a cover plate 2, a lock tongue 3, a lock buckle 4, a contact switch 5, a locking mechanism 6, a control system 7 and a power supply 8, wherein:

The cover plate 2 is hinged on the box body 1, the outer cornice of the cover plate 2 is provided with a lock tongue 3, and the inner cornice of the box body 1 is provided with a lock buckle 4, wherein the middle parts of the lock tongue 3 and the lock buckle 4 are provided with the same size through holes. The contact switch 5 is arranged on the side of the lock 4. The locking mechanism 6 includes a guide rail 61, a slider 62, a screw rod 63 and a steering gear 64. The guide rail 61 is fixedly installed in the box 1 by bolts, and the slider 62 It is movably installed in the guide rail 61, the screw rod 63 is rotated and installed in the guide rail 61 through the bearing and passes through the slider 62, and a thread transmission is formed between the screw rod 63 and the slider 62, so when the screw rod 63 rotates, the slider 62 is It will move linearly along the guide rail 61, the side of the slider 62 is provided with a lock rod 621, and there is a gap between the lock rod 621 and the screw rod 63, so there will be no movement interference between the lock rod 621 and the screw rod 63, and the rudder The motor 64 is installed on the side of the guide rail 61 by bolts, the power output end of the steering gear 64 is fixedly connected with the screw rod 63, and the steering gear 64 is electrically connected with the power supply 8 to supply power for the rotation of the steering gear 64. When the box body 1 is installed, the centers of the lock tongue 3, the lock buckle 4 and the lock rod 621 are on the same straight line, so the lock rod 621 can enter the through hole in the middle of the lock tongue 3 and the lock buckle 4 to realize the locking of the cover plate 2;

The control system 7 includes a microcontroller, a photoelectric sensor, a wireless module, an electromagnetic relay, and a buzzer, and the microcontroller, the photoelectric sensor, the wireless module, the electromagnetic relay, and the buzzer are electrically connected to the power supply 8 respectively, so the power supply 8 is: The components in the control system 7 are independently powered, wherein the photoelectric sensor, the wireless module, the electromagnetic relay and the buzzer are respectively electrically connected with the microcontroller. The microcontroller is the control unit with the ATmega328 as the main control chip, and then the microcontroller The device is used to process the received electrical signals and send control signals. The wireless module is the ESP8266 wireless signal transmission component, and the ESP8266 wireless signal transmission component can form a wireless connection with the deliveryman's mobile terminal, but the ESP8266 wireless signal transmission component cannot be received at the mobile terminal. When the WIFI signal is transmitted, the wireless connection between the two is disconnected, the contact switch 5 is electrically connected with the microcontroller, and the steering gear 64 is electrically connected with the electromagnetic relay. The photoelectric sensor is arranged at the bottom of the box 1, and the photoelectric sensor There is also a matching refractive plate, then when the photoelectric sensor starts and emits light, the refractive plate refracts the light back, and the photoelectric sensor realizes the effect of detecting the position.

The use principle of the utility model: firstly, the ESP8266 wireless signal transmission component forms a WIFI wireless connection with the mobile phone terminal of the takeaway, and when the ESP8266 wireless signal transmission component maintains the wireless connection with the mobile phone terminal, the microcontroller will receive the connection information transmitted by the terminal;

The terminal will be far away from the ESP8266 wireless signal transmission component when the food is delivered by the takeaway, then the WIFI connection between the two is disconnected when the range of the wireless connection between the ESP8266 wireless signal transmission component and the terminal is exceeded. At this time, the microcontroller receives the disconnection The connected signal, the microcontroller sends the start signal and transmits it to the electromagnetic relay, then after the electromagnetic relay is energized, it will be energized synchronously with the steering gear 64 that is electrically connected to it. At this time, the steering gear 64 starts and drives the screw 63 to rotate. At this time, the slider 62 will move linearly along the guide rail 61, and the lock rod 621 enters the through hole in the middle of the lock tongue 3 and the lock buckle 4 to lock the cover plate 2. When the lock rod 621 contacts the contact switch 5 At this time, the steering gear 64 stops outputting power. At this time, the contact switch 5 transmits the connection signal to the microcontroller. At this time, the microcontroller sends an electrical signal to control the activation of the photoelectric sensor. Then the light emitted by the photoelectric sensor plays the role of the refractor. If the photoelectric sensor can detect the photoelectric signal, and then achieve the effect of detecting the box 1, if someone removes the box 1 from the vehicle, the photoelectric sensor can not detect the photoelectric signal, then the photoelectric sensor will The signal that the photoelectric sensor is disconnected will be transmitted to the microcontroller. At this time, the microcontroller will issue an electrical signal to control the opening of the buzzer, then the box 1 will alarm to achieve the effect of anti-theft;

When the ESP8266 wireless signal transmission component and the mobile phone terminal re-establish a wireless connection, the microcontroller sends a start signal and transmits it to the electromagnetic relay. After the electromagnetic relay is energized, it will synchronously energize the steering gear 64 that is electrically connected to it, thereby driving the slider. The block 62 moves in the direction away from the lock tongue 3 and the lock catch 4, thereby completing the effect of automatic unlocking;

If the ESP8266 wireless signal transmission component keeps the wireless connection with the mobile phone terminal when the deliveryman is not far from the box 1, and the lock lever 621 is in the state of being separated from the lock tongue 3 and the lock buckle 4, then the lock lever 621 will not touch the contact. type switch 5, so the photoelectric sensor does not work, so the buzzer alarm will not occur when it is moved to the box 1 at this time.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
