Description

Technical Field

[0001] This utility model relates to the field of supermarket monitoring equipment, and in particular to a monitoring structure for unmanned supermarkets. Background Technology

[0002] Unmanned supermarkets are intelligent retail stores that utilize advanced technologies such as the Internet of Things and artificial intelligence to enable self-service shopping and automatic checkout, aiming to improve shopping efficiency and reduce labor costs.

[0003] In unmanned supermarkets, surveillance devices are crucial for reducing theft and assisting with checkout. Most existing surveillance devices are installed directly inside the supermarket or outside the entrances and exits. Over time, they may be subject to various unexpected situations such as wind and rain, collisions with foreign objects, or even human damage. If the surveillance device is damaged or malfunctions, the safety of the goods in the supermarket cannot be guaranteed. Furthermore, if the surveillance device itself is damaged, the staff will not be able to know immediately, which can easily lead to theft in the supermarket due to information gaps. Utility Model Content

[0004] The purpose of this utility model is to provide a monitoring structure for unmanned supermarkets, which solves the problem that the monitoring devices in unmanned supermarkets lack effective protection. If they encounter emergencies such as damage or changes in orientation, they will not be able to monitor effectively. Furthermore, if the monitoring device is damaged, the staff will not know in time, which may easily lead to theft.

[0005] To address the existing technical problems, the technical solution of this utility model is as follows: A monitoring structure for an unmanned supermarket includes a monitor and a placement slot for holding the monitor. The opening end of the placement slot is covered with a partition, and a sleeve is provided on the inner wall of the placement slot. A mounting plate with the monitor mounted on its surface is provided at the end of the sleeve. A spring is provided between the mounting plate and the placement slot. An annular magnetic sheet is provided on the surface of the mounting plate near the spring. An electromagnet is provided on the inner wall of the placement slot. A contact switch is provided on the side of the mounting plate near the spring. The contact switch, the monitor, and the electromagnet are all electrically connected to an electronic control component.

[0006] Furthermore, the partition consists of a frame and a closing plate. The frame is set along the edge of the placement slot, and the closing plate is set inside the frame. The closing plate has a perforation on the side near the monitor, and the edge of the placement slot has an inclined chamfer. This ensures that the monitor can protrude outward through the perforation while the rest of the monitor does not come into contact with the outside world, reducing the impact of the external environment on the monitor. In addition, when the monitor enters the placement slot, the inclined chamfer will not block the monitoring area of ​​the monitor, ensuring that the monitoring effect of the monitor is not affected by its location.

[0007] Furthermore, the monitor is a spherical monitoring device, with its monitoring part protruding outward through a perforation in the partition's sealing plate. The sealing plate is made of transparent tempered glass, ensuring that the monitor can monitor from the inside of the placement slot outward through the partition.

[0008] Furthermore, the spring is always in a relaxed state and is located at the center of the mounting plate. The annular magnetic sheet is sleeved on the outside of the spring, and the spring can always push the mounting plate to make the monitor protrude out of the partition.

[0009] Furthermore, the electromagnet is a ring magnet, which is adapted to the ring magnetic sheet, and the electromagnet is always kept in a normally closed state. Under normal conditions, the electromagnet will not generate an attractive force with the ring magnetic sheet.

[0010] Furthermore, the sensing end of the contact switch faces the placement groove, and the contact switch is located inside the spring. The distance between the contact switch and the placement groove is the same as the distance between the annular magnetic sheet and the electromagnet. The inner wall of the placement groove is provided with a soft rubber seat aligned with the contact switch to ensure that the contact switch does not block the annular magnetic sheet from contacting the electromagnet after contacting the inner wall of the placement groove, and to buffer the contact between the contact switch and the placement groove to avoid damage to the contact switch.

[0011] Furthermore, the electronic control component is an electronic control processing device with an interconnected delay circuit, a processor, and a signal transceiver. The delay circuit is connected to the electromagnet, and the signal transceiver is connected to the contact switch through a monitor. The delay circuit in the electronic control component can change the switch state of the electromagnet and restore it within a finite time. The contact switch can send signals to the outside through the signal transceiver.

[0012] Furthermore, the maximum contraction length of the spring is greater than the length of the part of the monitor that protrudes through the hole, ensuring that the monitor will not be blocked by the contraction length of the spring during the retraction process.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. A mounting slot on the wall surface provides an installation space for the main unit of the monitor, so that only the monitoring part of the monitor is exposed on the outside. In case of emergencies, this ensures that the monitor is not easily damaged and improves its service life under various conditions. A contact switch is installed between the monitor and the mounting structure. When the contact switch is activated, it can send a signal to the sales staff through the electrical control components to alert them to the emergency and handle it as soon as possible.

[0015] 2. When the monitor is damaged by human intervention, it will retract into the placement slot under the pressure. During the movement, the contact switch contacts the inner wall of the placement slot and sends an electrical signal to activate the electromagnet. The electromagnet can fix the mounting plate of the monitor in place and release it again after a certain period of time, allowing the monitor to be temporarily stored in the placement slot to avoid continuous acts of vandalism. While inside the placement slot, it can still monitor the outside through the partition, ensuring that the monitor can continue to monitor without being damaged. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-4 As shown, an unmanned supermarket monitoring structure includes a monitor 1 and a placement slot 2 for housing the monitor 1. The opening end of the placement slot 2 is covered by a partition 3. The partition 3 consists of a frame and a closing plate. The frame is set along the edge of the placement slot 2, and the closing plate is set inside the frame. A perforation is opened on the side of the closing plate near the monitor 1, and the edge of the placement slot 2 is provided with an inclined chamfer to ensure that the monitor 1 can protrude outward through the perforation while the rest of the monitor 1 does not come into contact with the outside world, reducing the impact of the external environment on the monitor 1. Furthermore, when the monitor 1 enters the placement slot 2, the inclined chamfer will not block the monitoring area of ​​the monitor 1, ensuring that the monitoring effect of the monitor 1 is not affected by its location. The monitor 1 is a spherical monitoring device, and its monitoring part protrudes outward along the perforation of the closing plate of the partition 3. The closing plate is made of transparent tempered glass, ensuring that the monitor 1 can monitor from the inside of the placement slot 2 through the partition 3.

[0023] A sleeve 4 is provided on the inner wall of the placement groove 2. A mounting plate 5 with a monitor 1 mounted on its surface is provided at the end of the sleeve 4. A spring 6 is provided between the mounting plate 5 and the placement groove 2. The maximum contraction length of the spring 6 is greater than the length of the monitor 1 protruding through the hole, ensuring that the monitor 1 will not be blocked by the contraction length of the spring 6 during the retraction process. An annular magnetic sheet 7 is provided on the side of the mounting plate 5 near the spring 6. The spring 6 is always in a relaxed state and is located at the center of the mounting plate 5. The annular magnetic sheet 7 is sleeved on the outside of the spring 6. The spring 6 can always push the mounting plate 5 to make the monitor 1 protrude through the partition 3.

[0024] An electromagnet 8 is installed on the inner wall of the placement slot 2. The electromagnet 8 is a ring magnet and is adapted to the ring magnetic sheet 7. The electromagnet 8 is always kept in a normally closed state. Under normal conditions, the electromagnet 8 will not generate an attraction between it and the ring magnetic sheet 7. A contact switch 9 is installed on the side of the mounting plate 5 near the spring 6. The sensing end of the contact switch 9 faces the placement slot 2 and the contact switch 9 is located inside the spring 6. The distance between the contact switch 9 and the placement slot 2 is the same as the distance between the ring magnetic sheet 7 and the electromagnet 8. A soft rubber seat is installed on the inner wall of the placement slot 2, which is aligned with the contact switch 9. This ensures that the contact switch 9 will not block the ring magnetic sheet 7 from contacting the electromagnet 8 after it comes into contact with the inner wall of the placement slot 2, and also buffers the contact between the contact switch 9 and the placement slot 2 to prevent damage to the contact switch 9.

[0025] Contact switch 9, monitor 1, and electromagnet 8 are all electrically connected to an electronic control component 10. The electronic control component 10 is an electronic control processing device with an interconnected delay circuit, a processor, and a signal transceiver. The delay circuit is connected to electromagnet 8, and the signal transceiver is connected to contact switch 9 through monitor 1. The delay circuit in electronic control component 10 can change the switching state of electromagnet 8 and restore it within a limited time. Contact switch 9 can send signals to the outside through the signal transceiver.

[0026] Working principle description: First, under normal use, the monitoring part of the monitor 1 protrudes outward through the perforations on the surface of the partition 3 to monitor the supermarket. Only the spherical part of the monitor 1 is exposed to the outside, and it is only affected by the outside environment.

[0027] When a man-made damage incident occurs, the monitor 1 is hit and pushed by the force to push the mounting plate 5 to compress the spring 6 and retract it to buffer the force during the impact. At the same time, during the movement of the mounting plate 5, the contact switch 9 moves along with it and contacts the inner wall of the placement slot 2 and opens. The contact switch 9 sends a signal to the electronic control component 10 to alert the sales staff that there is an unexpected situation.

[0028] When the contact switch 9 is turned on, the electromagnet 8 contacts the annular magnetic sheet 7. At this time, the contact switch 9 sends an electrical signal to the electronic control component 10, which causes the electronic control component 10 to start the electromagnet 8. The electromagnet 8 remains turned on for a certain period of time and is attracted to the mounting plate 5 by the annular magnetic sheet 7. When the position of the mounting plate 5 is fixed, the monitor 1 enters the partition 3 and observes the outside through the partition 3. After a certain period of time, the electromagnet 8 is turned off, the annular magnetic sheet 7 loses its attraction, and the mounting plate 5 is pushed back to its original position under the action of the spring 6. The monitor 1 then protrudes out of the partition 3 to monitor the outside again.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
