[0002] With the popularization of information technology in teaching, teachers are using electronic devices (such as smartphones, tablets, and laptops) more frequently in the classroom. To meet the charging needs of these devices, many classrooms are equipped with charging cabinets or charging stations. However, traditional charging solutions have the following problems: 1) Charging cabinets are set up independently, requiring additional classroom space and affecting the overall classroom layout. This can cause poor circulation or overcrowding, especially in classrooms with limited space. Moreover, charging cabinets are usually separated from the podium, requiring teachers to frequently travel between the podium and the charging cabinet during class, affecting teaching efficiency. 2) If a traditional podium is equipped with charging functionality, it usually uses an external socket or fixed wiring, resulting in charging cables being exposed for long periods, easily becoming tangled, knotted, or even damaged by pulling. Furthermore, when multiple devices are charging simultaneously, the cables become tangled and messy, affecting aesthetics. Therefore, there is an urgent need for a charging cabinet solution that can optimize cable management and improve ease of use. Utility Model Content

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment provides an intelligent lectern charging cabinet, including a lectern body 1, with the top surface of the lectern body 1 serving as a lectern, and a charging cavity 100 provided below.

[0030] A power supply box 200 is located inside the charging cavity 100, at the top of the charging cavity 100. The power supply box 200 contains a power supply unit, which is connected to an external power source (such as AC power) to provide power for charging electronic devices. The power supply unit includes, but is not limited to, circuit boards, energy storage power supplies, power filters, DC-DC modules, charging ICs, and current sensors.

[0031] The front of the power supply box 200 is equipped with several charging ports 210, which are electrically connected to the power supply unit. These ports include, but are not limited to, USB ports and Type-C ports. Each charging port 210 is also equipped with an LED indicator.

[0032] A power switch is also provided on the front of the power supply box 200 to control the on / off state of the power supply box 200 circuit.

[0033] Inside the charging chamber 100 and below the power supply box 200, there is a first charging area 110 and a second charging area 120. The first charging area 110 is located above the second charging area 120, and the two are separated by a support plate 300. The top of the support plate 300 is provided with several partitions 400 that are spaced apart from each other.

[0034] The first charging area 110 is used to charge lightweight electronic products such as mobile phones and tablets. The space created by the partitions 400 on the tray 300 is used to place these electronic products, which facilitates neat placement of these products and saves storage space.

[0035] The second charging area 120 can be used to house heavy electronic products such as computer mainframes and servers. A power outlet can be installed in the second charging area 120, which is electrically connected to the charging unit, providing power and charging functionality for these products.

[0036] The second charging area 120 is equipped with an intelligent control box 500, which is connected in series in the power supply circuit of the power supply box 200. The intelligent control box 500 is equipped with a microcomputer time control switch. The microcomputer time control switch can wirelessly connect to a mobile terminal (such as a mobile phone or tablet) to intelligently control the on / off state of the power supply circuit. Circuit breakers and relays can also be installed on the intelligent control box 500.

[0037] A cooling fan 600 is provided on the left and / or right sidewalls of the lectern body 1. The upper half of the cooling fan 600 corresponds to the power supply box 200, and the lower half corresponds to the first charging area 110, so as to dissipate heat from the electronic devices being charged in both the power supply box 200 and the first charging area 110 simultaneously. The cooling fan 600 is electrically connected to the power supply unit inside the power supply box 200.

[0038] Furthermore, at least the left and right side walls of the charging cavity 100 are provided with several columns 700. The side of the power supply box 200 and the side of the support plate 300 are connected to the columns 700, and gaps are left between them and the side walls of the charging cavity 100. The cooling fan 600 is located on the inner side of the side wall of the podium body 1. By setting the columns 700, not only can the podium body 1 be supported and its structural strength strengthened, but the power supply box 200, the first charging area 110 and the second charging area 120 can also be connected at the side wall of the charging cavity 100, which facilitates airflow and heat dissipation.

[0039] The left and / or right sidewalls of the lectern body 1 are preferably provided with heat dissipation holes 800 corresponding to the first charging area 110, so as to provide convection and heat dissipation openings for airflow in the charging cavity 100 and enhance the heat dissipation effect.

[0040] The front of the lectern body 1 is provided with a double door 900, and an observation window 910 is provided at the position of the charging interface 210 on the power supply box 200 corresponding to the double door 900.

[0041] The bottom wall of the power supply chamber has a through hole for connecting the mains power line.

[0042] The charging cabinet provided in this embodiment integrates with the podium, eliminating the need for a separate charging cabinet and saving classroom space. Furthermore, teachers can directly access and charge their devices during class, reducing walking time and improving teaching efficiency. Charging within the cabinet also prevents tripping hazards and maintains a neat and aesthetically pleasing appearance.

[0043] Example 2

[0044] like Figure 2 As shown, the intelligent lectern charging cabinet provided in this embodiment is basically the same as that in Embodiment 1. The difference is that the partition 400 is a cavity structure, and a cable receiving cavity 410 is formed inside it. A charging cable 420 is provided in the cable receiving cavity 410. One end of the charging cable 420 extends from the rear of the partition 400 and is electrically connected to the power supply unit of the power supply box 200. The other end extends from the front of the partition 400 and is connected to a charging plug 421.

[0045] A portion of the charging cable 420 near its rear end is fixed to the partition 400.

[0046] The cable retraction cavity 410 is also equipped with an automatic cable retraction mechanism 430, and the charging cable 420 is configured to be pulled out to the use position or automatically retracted back to the original position.

[0047] The charging plug 421 with multiple partitions 400 covers, but is not limited to, Micro-USB, Type-C, and Lightning plugs.

[0048] Compared to Embodiment 1, this embodiment further enables charging of electronic products that do not have a built-in charging cable 420 and charging plug 421. Moreover, the charging cable 420 adopts a hidden, automatically retractable structure, achieving automatic cable retraction and preventing exposed cables. This keeps the wiring inside the charging cabinet neater and avoids tangling or incorrect cable removal when charging multiple electronic devices. When there are only a few electronic devices, prioritizing the use of the charging cables 420 on the partition 400 will make charging more convenient.

[0049] In detail, the automatic take-up mechanism 430 includes a pair of winding shafts 431, which are distributed front to back and staggered vertically. The two ends of the winding shafts 431 are connected to the left and right sidewalls of the take-up cavity 410, with one winding shaft 431 fixedly connected to the sidewall of the take-up cavity 410 and the other slidably connected. The charging cable 420 is wound in an S-shape around the winding shaft 431. A spring 432 connects the slidably connected winding shaft 431 to the sidewall of the take-up cavity 410, and is configured to stretch the spring 432 when the charging cable 420 is pulled forward.

[0050] In this embodiment, the slidably connected winding shaft 431 is located below and behind another winding shaft 431. The rear end of the charging cable 420 bends and extends backward after passing over the fixed winding shaft 431, and the front end of the charging cable 420 bends and extends forward after passing over the sliding winding shaft 431.

[0051] When the charging plug 421 is pulled, the charging cable 420 is pulled forward. The winding shaft 431, which slides under the action of the charging cable 420, slides forward to provide the length for the charging cable 420 to be pulled out. At this time, the spring 432 is stretched.

[0052] Both winding shafts 431 can be equipped with pulleys 433 to change the sliding friction between the charging cable 420 and the winding shaft 431 to rolling friction, thereby reducing the wear of the charging cable 420.

[0053] The diameter of pulley 433 is preferably 30-50mm. If pulley 433 is not provided, the diameter of winding shaft 431 is preferably 30-50mm to avoid excessive bending of charging cable 420 and damage to the cable.

[0054] Furthermore, the left and right sidewalls of the partition plate 400 are provided with horizontal slots 434 corresponding to the sliding positions of the winding shaft 431. The two ends of the winding shaft 431 slide in the slots 434, and the spring 432 is also located in the slots 434. One end of the spring 432 is connected to the winding shaft 431, and the other end is connected to one end of the slots 434.

[0055] The slot 434 not only guides the sliding of the winding shaft 431, but also serves as a heat dissipation hole during charging of the electronic device. In addition, the slot 434 reduces the thickness of the take-up cavity 410, making it similar in thickness to the charging cable 420, thereby reducing the thickness of the separator 400.

[0056] In this embodiment, the partition 400 has a cable slot 440 on the front side. When charging is required, the charging cable 420 is pulled out and the cable is locked in the cable slot 440 to prevent the charging cable 420 from retracting, thus clamping and locking the charging cable 420.

[0057] Specifically, the front of the partition 400 is provided with a pick-and-place slot 450, with its opening facing the left or right side of the partition 400, for accommodating the charging plug 421. The rear side of the pick-and-place slot 450 is provided with a cable outlet 460 communicating with the cable take-up cavity 410, and the front side is provided with an Ω-shaped cable retaining groove 440. The opening direction of the cable retaining groove 440 is the same as that of the pick-and-place slot 450, the cable retaining groove 440 is aligned front-to-back with the cable outlet 460, and the cable retaining groove 440 extends through the pick-and-place slot 450 and the front side of the partition 400.

[0058] Preferably, elastic anti-abrasion pads can be fixedly connected to the inner surfaces of both the wire outlet 460 and the wire clamping groove 440.

[0059] In addition, a first magnet (not shown in the figure) may be provided in the pick-and-place slot 450. A second magnet (not shown in the figure) that cooperates with the first magnet is provided on the charging plug 421. When the charging cable 420 is retracted, the charging plug 421 is positioned in the pick-and-place slot 450 by the attraction of the first magnet to the second magnet.

[0060] In this embodiment, a power supply bus 470 extending laterally and electrically connected to the power supply unit is provided on the inner side of the rear wall of the cabinet. A male connector 422 is provided at one end of the charging cable 420 extending from the rear of the partition 400. Female connectors 471 branch off from the power supply cable at the corresponding positions of each partition 400, connecting with the male connector 422. This simplifies and organizes the wiring in the first charging area 110, and also facilitates the individual disassembly of the partition 400 for replacement or rational spatial layout.

[0061] In addition, in this embodiment, a current detection module 480 is also provided in the take-up cavity 410, which is connected in series with the charging cable 420 and located near the rear end of the charging cable 420. The current detection module 480 includes a Hall sensor and an overload protector.

[0062] Example 4

[0063] like Figure 3 As shown, the charging cabinet provided in this embodiment is basically the same as that in embodiment three. The difference is that the two winding shafts 431 are slidably connected to the side wall of the take-up cavity 410, and springs 432 are connected to both ends of each winding shaft 431.

[0064] When the charging cable 420 is pulled outward, the two winding shafts 431 slide towards each other, and the springs 432 connected to the two winding shafts 431 are stretched.

[0065] The partition 400 is provided with a slot 434 at each of the two winding shafts 431. For the specific structure and connection method, please refer to the description of Embodiment 3, which will not be repeated here.

[0066] By making both winding shafts 431 slidable, the elongation of the spring 432 when a single winding shaft 431 slides can be reduced, the stress level of the spring 432 is reduced by about 50%, effectively delaying material fatigue of the spring 432 and extending its overall service life.
