[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] The existing electrically adjustable electric desks and chairs need to be powered by electricity when in use. The through slots are powered by power lines. However, this method requires pre-buried cable ducts during renovation, which makes the renovation of some older classrooms more complicated. Therefore, in order to solve the above problems, this case proposes the following technical solutions:

[0041] See also Figures 1 to 9 The present invention provides a technical solution for a smart lunch break table and chair control system: the structure includes: a podium 1, a desk 5, and a seat 6. The surface of the podium 1 is installed with a controller 2 and a display 3. The desk 5 and the seat 6 are installed in a set at the adjacent part of the podium 1. The desk 5 includes a desktop 51 and an identifier 52. The side of the bracket of the desktop 51 is provided with a power supply device 53 for shell rotation, and the bracket of the desktop 51 is nested with the table leg 54 at the bottom. The table leg 54 is provided with a motor for driving the desktop 51 bracket to rise and fall. The table leg 54 is connected to the chair frame 61 through a wire groove 55.

[0042] The seat 6 includes a chair frame 61, a liftable seat cushion 62 is arranged on the top of the chair frame 61, a backrest 64 and a leg rest 65 are respectively installed on both sides of the seat cushion 62, and a driving rod 63 is arranged between the seat cushion 62 and the backrest 64, and the angle between the backrest 64 and the seat cushion 62 is controlled by the driving rod 63.

[0043] The structure of the intelligent desk and chair includes a platform 1, and a controller 2 and a display 3 are provided on the surface of the platform 1. The controller 2 can transmit a signal to control the desk 5 and the chair 6 to rise and fall and enter a lunch break mode. The specific desk 5 is composed of a desktop 51 and a table leg 54. The table leg 54 is equipped with a motor, and the motor drives the screw rod to push the desktop 51 to rise and fall. The power supply device 53 supplies power to the motor inside the table leg 54 and the chair frame 61. The surface of the desktop 51 is also provided with an identifier 52, which uses a camera to detect the sitting posture and can remind students to make timely corrections.

[0044] The seat 6 includes a chair frame 61, a seat cushion 62 is provided on the top of the chair frame 61, a driving rod 63 is installed at the rear end of the seat cushion 62, and the driving rod 63 is used to control the angle of the backrest 64. A leg rest 65 is installed at the front end of the seat cushion 62. When the backrest 64 is leaning against the leg rest 65 and unfolded, the backrest 64 can be laid flat.

[0045] In order to solve the problem of difficult wiring, the present application adopts a power supply device 53 for power supply, wherein the desk 5 and the seat 6 are connected by a wire trough 55, and the power supply device 53 is installed on the side of the desktop 51 and is powered by a battery pack 531. The specific wire trough 55 is a metal wire trough, and the bottom can be fixed by gluing or punching. The arc-shaped structure can avoid hindering students' daily activities.

[0046] In order to protect the battery pack 531 and facilitate unified management, the limiting shell 532 is controlled by the first driver 534, and when it is rotated to the bracket groove of the desktop 51, the battery pack 531 is engaged in the bracket to prevent students from disassembling it at will.

[0047] The battery pack 531 contacts the contact 533 inside the limiting shell 532, and the contact 533 is connected to the wire through the guide plate 335 welded to the sheet 331. Then the wire passes through the axial wire groove 535 and the through groove in the center of the first driver 534 to supply power to the table legs 54 and the chair frame 61.

[0048] The battery 315 is installed inside the shell 312 of the battery pack 531. There are two batteries 315. A middle hole is provided in the middle of the shell 312 for the side plate 316 to move. The middle hole not only facilitates the horizontal movement of the side plate 316 when the control rod 318 is rotated, but also improves the heat dissipation of the battery 315 and increases the service life. The control rod 318 is controlled by a second driver 314 installed in the middle of the driving board 313. Specifically, the driving board 313 includes a power management chip for managing charging and discharging protection, and a wireless receiving and transmitting chip, which is mainly used to transmit the information detected by the identifier 52 to the display 3 on the surface of the podium 1 for convenient management, and at the same time, when the controller 2 issues instructions, it can receive them uniformly.

[0049] Since the battery 315 needs to be charged regularly, this solution adopts a manual disassembly method, and the battery pack 531 is placed on the storage tank 4 on the surface of the podium 1 for centralized charging. Specifically, when the battery pack 531 is disassembled for easy management on Friday, the controller 2 sends a signal to rotate the first driver 534 to rotate to the position as shown in the figure. Figure 7 After the state is reached, the second driver 314 rotates the control rod 318 to unlock it. While unlocking, the control rod 318 drives the side panels 316 on both sides to retract inward, reducing the friction between the contactor 317 and the contact 533, and protecting the contact. It is also convenient for disassembly to avoid students having to pull it hard to take it out. The battery packs 531 after being taken out are sequentially inserted into the storage slots 4 on the surface of the podium 1 for centralized charging. This management method can not only manage the charging of the battery pack 531, but also avoid excessive power consumption of the battery pack 531 and increase its service life.

[0050] Due to the need for regular disassembly, it is inevitable that the surfaces of the contacts 533 and the contactor 317 are oxidized, which in turn affects the power supply state. The most direct cause is that the conductivity between the contact points is reduced, causing the contacts to heat up and easily cause failures.

[0051] The device is optimized in this regard. One is to improve the structure of the side plate 316. The side plate 316 is provided with a plate body 161. The plate body 161 is U-shaped and has horizontal plates on the top and bottom, which can be embedded in the groove of the shell 312. A push rod 162 extends inward from the plate body 161. An inner hole is provided at the end of the push rod 162. The inner hole is divided into a straight hole that passes through the rod body of the control rod 318, and a horizontal hole that cooperates with the horizontal bar on the rod body of the control rod 318. When rotating, the cross bar interferes with the horizontal hole, thereby pushing the push rod 162 to move, squeezing the plate body 161 and the buffer rod 164 inward, so that the contactor 317 and the contact 533 are quickly separated. This method can be used for regular disassembly operations.

[0052] When the contacts need to be cleaned regularly, the control rod 318 does not rotate, and the spring force of the buffer rod 164 causes the contactor 317 on the surface of the side plate 316 to be aligned with the contact 533. The sheet 331 of the side plate 316 is provided with a protrusion 334, which contacts the contactor 317 through the protrusion 334. In order to increase the contact pressure, a support rod 332 and a reset spring 333 are provided inside the protrusion 334, and the extrusion force is further increased by the reset spring 333. The surface of the protrusion 334 is a plane, and the bottom plate 171 of the contactor 317 serves as a plane contact in contact with the protrusion 334. The main material is copper sheet, which can improve conductivity. The surface of the bottom plate 171 is provided with a slide rail 172, which is used to contact the guide ring 173 through the slide rail 172. The rows are nested and matched. When disengaging, the protrusion 334 is first located in the frame in the middle of the guide ring 173, and the guide ring 173 is driven to slide as it is dragged. During the sliding process, the guide ring 173 scrapes and cleans the surface of the bottom plate 171, and when the protrusion 334 is separated from the bottom plate 171 by the scraping, the pressure plate 174 installed on the guide ring 173 will cover the scraped surface to reduce oxidation. When reinstalling, the protrusion 334 will contact the pressure plate 174, and the surfaces of the pressure plate 174 and the protrusion 334 will be cleaned. After cleaning, the protrusion 334 slides and buckles into the frame of the guide ring 173. Since the stroke has not yet been reached, the guide ring 173 will be further pushed to move, and the part blocked by the pressure plate 174 for cleaning will contact the protrusion 334 when the layer thickness is reached.

[0053] The improved device sends a signal to the power supply device 53 through the controller 2 on the surface of the podium 1 to control the desk 5 to rise. The backrest 64 of the seat 6 tilts backward under the action of the driving rod 63, and the leg rest 65 is lifted forward, so that the student's lunch break table and chair enter the sleep mode, making the student's nap more comfortable. In addition, the surface of the desktop 51 is provided with an identifier 52 for sitting posture monitoring. Abnormal sitting posture will send a signal to the display 3, which will prompt the teacher to supervise and facilitate management through the display 3.

[0054] The internally powered battery pack 531 is protected by a rotating limit shell 532 to prevent students from disassembling the battery pack 531 for playing during use. The contacts are in sliding cooperation with the bottom plate 171 and the guide ring 173. After the inner frame of the guide ring 173 slides away, the pressure plate 174 covers it to reduce oxidation and provide covering protection. During installation, the guide ring 173 moves in the opposite direction, and the protrusion 334 fits with the protection area covered by the pressure plate 174 to improve the conductivity of the contact surface. A second driver 314 is provided inside the outer shell 312 to control the rotation and locking of the control rod 318 to improve the overall safety.

[0055] The above only describes the basic principles and preferred embodiments of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present invention.

[0056] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
