Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging laptop expansion devices, and specifically relates to a wireless charging laptop expansion device. Background Technique

[0002] Wireless charging technology originates from wireless power transmission technology. Its principle is that energy is transmitted between the charger and the electrical device by means of a magnetic field. It can be divided into two types: low-power wireless charging and high-power wireless charging. Low-power wireless charging often adopts electromagnetic induction; high-power wireless charging often adopts resonance, and the power supply device transmits energy to the electrical device.

[0003] During the charging process of existing wireless charging laptops, the heat dissipated is more than that during non-charging use. Because the computer's heat dissipation ports are located on the bottom surface of the laptop, and the computer is placed on the desktop, the laptop cannot be effectively cooled during the wireless charging process.

[0004] Existing laptop wireless charging cannot lift the laptop away from the desktop to enable the cooling fan to dissipate heat effectively, which easily causes the laptop hardware to malfunction due to overheating. Prolonged abnormal operation can easily lead to damage to the laptop.

[0005] Therefore, a new solution is needed to solve this problem. Content of the Utility Model

[0006] Aiming at the problem in the above background technique that the existing technology cannot lift and enhance heat dissipation when wirelessly charging a laptop.

[0007] A wireless charging laptop expansion device disclosed by the utility model includes a charging rack. Two screw rods are rotatably connected to the inner wall of the charging rack. A pulley is fixedly connected to the top end of each screw rod. A transmission belt is arranged above the charging rack. The inner wall of the transmission belt is drivingly connected to both pulleys. A connecting piece is threadedly connected to the outer surface of each screw rod. The outer surface of each connecting piece is slidably connected to the charging rack. A connecting block is rotatably connected to the outer surface of each connecting piece. A support plate is slidably connected to the inner wall of the charging rack. The outer surface of the support plate is fixedly connected to both connecting blocks.

[0008] Furthermore, a placement box is fixedly connected to the upper surface of the charging rack. The inner wall of the placement box is rotatably connected to both pulleys. Fixing bolts are threadedly connected to both sides of the charging rack.

[0009] Furthermore, a rotating wheel is rotatably connected to the inner wall of the placement box. The bottom surface of the rotating wheel is fixedly connected to one of the pulleys.

[0010] Further, a wireless charging board and a baffle are fixedly installed on the upper surface of the support plate. A laptop body is arranged above the support plate. A wireless charging groove is formed in the bottom surface of the laptop body. The outer surface of the wireless charging board is inserted into the wireless charging groove. A cooling fan is fixedly installed on the bottom surface of the laptop body.

[0011] Further, two springs are arranged inside the support plate. One ends of the two springs close to each other are fixedly connected to the support plate.

[0012] Further, two clamping plates are slidably connected to the inner wall of the support plate. One ends of the two clamping plates close to each other are fixedly connected to the corresponding springs.

[0013] Further, the outer surface of each clamping plate is slidably connected to the laptop body, and the outer surface of the baffle is slidably connected to the laptop body.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By arranging components such as a charging rack, a screw rod, a pulley, a transmission belt, a connecting piece, a connecting block, and a support plate, when the screw rod is rotated, the corresponding connecting piece moves vertically along the screw rod. At this time, the connecting piece drives the support plate to move vertically on the charging rack. The two pulleys are connected by the transmission belt, so that the two screw rods rotate synchronously, making the vertical movement of the support plate more stable. Thus, the device can lift the height of the laptop during charging through the vertical movement of the support plate, improving the heat dissipation efficiency.

[0016] 2. By arranging components such as a baffle, a laptop body, a clamping plate, a spring, and a support plate, the laptop body is slid down along the baffle, and then the two clamping plates are pulled. The clamping plates clamp the laptop body. At this time, the spring is stretched, and under the action of its own resilience, the clamping plate has resilience and presses and fixes the laptop body. Thus, the device can fix the position of the laptop body through the mutual cooperation of the clamping plate and the baffle. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figure 1 - Figure 5 , a wireless charging notebook computer expansion device of the present utility model, includes a charging stand 1. The charging stand 1 serves as the assembly for wireless charging of the notebook computer. Two screws 2 are rotatably connected to the inner wall of the charging stand 1. A pulley 3 is fixedly connected to the top end of each screw 2. Each pulley 3 is rotatably connected to the upper surface of the charging stand 1. A transmission belt 4 is provided above the charging stand 1. The inner wall of the transmission belt 4 is in transmission connection with both pulleys 3. The two pulleys 3 are connected by the transmission belt 4. When one of the screws 2 rotates, the other screw 2 will rotate synchronously through the corresponding pulley 3 and the transmission belt 4.

[0026] In this embodiment, a connecting member 5 is threadedly connected to the outer surface of each screw 2, and the outer surface of each connecting member 5 is slidably connected to the charging rack 1. The connecting member 5 is an L-shaped plate, and a connecting block 7 is rotatably connected to the outer surface of each connecting member 5. A support plate 8 is slidably connected to the inner wall of the charging rack 1, and the outer surface of the support plate 8 is fixedly connected to both connecting blocks 7. Specifically, the synchronous rotation of the two screws 2 will drive the corresponding connecting members 5 to move vertically along the corresponding screws 2. At this time, the connecting member 5 can drive the support plate 8 to move vertically along the charging rack 1. By rotating the support plate 8, the support plate 8 can rotate around the central axis where the connecting block 7 is connected to the corresponding connecting member 5, so as to store the support plate 8. When the support plate 8 is unfolded, the bottom surface of the support plate 8 will squeeze the connecting member 5 and support it.

[0027] As Figure 1 , Figure 2 , Figure 3 shown, a placement box 10 is fixedly connected to the upper surface of the charging rack 1. The placement box 10 serves as a protection box for the pulley 3 and can also prevent fingers from being inserted and causing damage. The inner wall of the placement box 10 is rotatably connected to both pulleys 3. Fixing bolts 11 are threadedly connected to both sides of the charging rack 1. Specifically, the charging rack 1 can be fixed to the desktop through the fixing bolts 11 to prevent it from tipping over during the charging process of the laptop and causing damage to the laptop.

[0028] In this embodiment, a runner 6 is rotatably connected to the inner wall of the placement box 10, and the bottom surface of the runner 6 is fixedly connected to one of the pulleys 3. Specifically, by rotating the runner 6, the runner 6 will drive the pulley 3 fixedly connected to it to rotate, thereby serving as a control mechanism for the vertical movement of the support plate 8.

[0029] As Figure 1 , Figure 2 , Figure 5 shown, a wireless charging board 9 and a baffle 16 are fixedly installed on the upper surface of the support plate 8. The wireless charging board 9 can output current. When it is not in contact with the wireless charging slot 17, no current is generated. The baffle 16 can block the laptop body 14 to prevent the laptop body 14 from falling during charging. Above the support plate 8 is provided with a laptop body 14, and a wireless charging slot 17 is opened on the bottom surface of the laptop body 14. The wireless charging slot 17 can perfectly fit with the wireless charging board 9. When the two fit, there is magnetic adsorption between them. The outer surface of the wireless charging board 9 is inserted into the wireless charging slot 17. A heat dissipation fan 15 is fixedly installed on the bottom surface of the laptop body 14. Specifically, first slide the laptop body 14 vertically along the baffle 16. At this time, the wireless charging slot 17 will fit and adsorb with the wireless charging board 9. During the startup process of the heat dissipation fan 15, the support plate 8 will not affect heat dissipation.

[0030] As Figure 2As shown, there are two springs 12 inside the support plate 8. One end of each of the two springs 12 close to each other is fixedly connected to the support plate 8. Specifically, the springs 12 are fixed in the middle of the support plate 8. Connecting columns are fixedly connected to both sides of the support plate 8. A chute is provided inside each connecting column, and the springs 12 are respectively located in the corresponding chutes.

[0031] As Figure 1 , Figure 2 shown, two clamping plates 13 are slidably connected to the inner wall of the support plate 8. One end of each of the two clamping plates 13 close to each other is fixedly connected to the corresponding spring 12. Specifically, when the clamping plate 13 is pulled, the clamping plate 13 will drive the corresponding spring 12 to stretch it. The clamping plate 13 will slide horizontally along the corresponding chute until the clamping plate 13 presses and clamps the notebook body 14. At this time, the spring 12 will act on the clamping plate 13 through its own elastic force and stably clamp the notebook body 14.

[0032] In this embodiment, the outer surface of each clamping plate 13 is slidably connected to the notebook body 14, and the outer surface of the baffle 16 is slidably connected to the notebook body 14. Specifically, when one of the clamping plates 13 is pulled, and then the notebook body 14 is slid down along the outer surfaces of the baffle 16 and one of the clamping plates 13, and then the clamping plate 13 is released. At this time, the clamping plate 13 will push the notebook body 14 to slide horizontally under the action of the restoring force of the spring 12 fixedly connected thereto until the wireless charging slot 17 fits with the wireless charging board 9.
