Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging PCBA, and in particular to an embedded wireless charging PCBA with an efficient heat dissipation structure. Background Art

[0002] A wireless charging transmitter circuit board (PCBA) refers to an electronic assembly used to implement wireless charging functionality. It primarily includes a circuit board (PCB) and various electronic components mounted on it. These components together form part of a complete wireless power transmission system, responsible for converting electrical energy into wireless signals and transmitting them to a receiving device. Wireless charging technology typically operates based on the principles of electromagnetic induction or magnetic resonance. At the transmitter, an alternating current passes through a coil to generate a varying magnetic field. This magnetic field can induce current in another coil near it (located in the receiving device), thereby charging the device. In existing technologies, wireless charging PCBAs are increasingly being applied. For example, embedding them in a desktop can give the table wireless charging functionality. While embedding them in a desktop can do the job, their heat dissipation performance is significantly reduced, which in turn reduces their service life when the temperature is too high. Therefore, an embedded wireless charging PCBA with an efficient heat dissipation structure is proposed to address the above issues. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] As a further improvement of the present invention, a filter is provided at the top of the fan, and the filter is fixedly connected to the bellows.

[0007] As a further improvement of the present invention, a spring is fixedly connected to the top inner side of the positioning plate, a card block is fixedly connected to the other end of the spring, and the card block is engaged with the wireless charging PCBA, the card block is slidably connected to the positioning plate, and the card block is spirally connected to the fixed plate.

[0008] As a further improvement of the present invention, an inclined fin is provided on the inner side of the transfer tube, and the fin is distributed in a ring shape. A rotating ring is fixedly connected to the top end of the fin, and the rotating ring is rotatably connected to the fixed plate.

[0009] As a further improvement of the present invention, a fixed box is provided at the bottom end of the inner side of the positioning plate, and the bottom end of the fixed box is rotatably connected to a handle that passes through the fixed box. The top of the handle is fixedly connected to a driving bevel gear, and the outer side of the driving bevel gear is meshedly connected to a driven bevel gear.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. An embedded wireless charging PCBA with an efficient heat dissipation structure. By installing a fan, filter, adapter tube, fins, rotating ring, and temperature sensor, the device is embedded in a desktop for use. When the temperature sensor detects that the device is at a high temperature during use, the fan draws external air through the filter for filtration. The air is then discharged through the air holes on the outside of the fixed tube and adapter tube, blowing toward the inclined fins. The rotating ring further drives the fins to rotate continuously, disturbing the heat dissipation gas. The disturbed heat dissipation air is then blown toward the wireless charging PCBA for heat dissipation before being discharged, achieving efficient heat dissipation for the device, thereby ensuring the service life of the device.

[0012] 2. An embedded wireless charging PCBA with an efficient heat dissipation structure. Through the provision of a driving bevel gear, a driven bevel gear, a threaded shaft, and a clamping rod, when the device is used, after the device is embedded in the desktop, the driving bevel gear is rotated by the handle to engage the driven bevel gear, further driving the threaded shaft to be spirally connected with the clamping rod. When the clamping rod is clamped into the slot provided on the desktop, the device embedded in the desktop is positioned, thereby ensuring the stability of the device when embedded in the desktop.

[0024] Example 3

[0025] like Figure 2 and Figure 4 As shown, in order to solve the problem of inconvenience in positioning the wireless charging PCBA1 on the top of the positioning plate 8, a spring 9 is fixedly connected to the top inner side of the positioning plate 8, and a clamping block 10 is fixedly connected to the other end of the spring 9, and the clamping block 10 is clamped and connected with the wireless charging PCBA1. The clamping block 10 is slidably connected to the positioning plate 8, and the clamping block 10 is spirally connected to the fixed plate 2. By making the clamping block 10 stuck on the outside of the wireless charging PCBA1 under the elastic force of the spring 9, it is convenient to position the wireless charging PCBA1 on the top of the positioning plate 8.

[0026] Example 4

[0027] like Figure 2-3 As shown, in order to solve the problem of poor heat dissipation effect of the device, an inclined fin 18 is provided on the inner side of the transfer tube 7, and the fin 18 is distributed in a ring shape. The top of the fin 18 is fixedly connected to a rotating ring 11, and the rotating ring 11 is rotatably connected to the fixed plate 2.

[0028] Example 5

[0029] like Figure 1 、 Figure 2 and Figure 4 As shown, in order to solve the problem that it is inconvenient to embed the device stably into the desktop, a fixed box 12 is provided at the bottom inner end of the positioning plate 8, and the bottom end of the fixed box 12 is rotatably connected to a handle 13 that passes through the fixed box 12, and the top of the handle 13 is fixedly connected to a driving bevel gear 14, and the outer side of the driving bevel gear 14 is meshed with a driven bevel gear 15, and the outer side of the driven bevel gear 15 is fixedly connected to a threaded shaft 16 that passes through the fixed box 12, and the threaded shaft 16 is rotatably connected to the fixed box 12 and the positioning plate 8, and the outer side of the threaded shaft 16 is spirally connected to a clamping rod 17, and the clamping rod 17 is slidably connected to the positioning plate 8.

When the clamping rod 17 is stuck in the slot opened on the desktop, the device is stably embedded in the desktop.

[0030] In this embodiment, when the device is embedded in the desktop for use, first control the card block 10 to clamp the wireless charging PCBA1 on the top of the positioning plate 8 under the elastic force of the spring 9, and then rotate the fixing plate 2 to screw the card block 10 on the outside of the wireless charging PCBA1 to stably position the wireless charging PCBA1, then embed the device into the desktop from the bottom of the desktop, and finally rotate the active bevel gear 14 through the handle 13 to engage the driven bevel gear 15, further driving the threaded shaft 16 to screw the card rod 17. When the card rod 17 is inserted into the card slot provided on the desktop, the device embedded in the desktop is stably positioned. After completing the above operations, when using the device, first set the temperature through the controller 20 after connecting to the external power supply. The sensing range of the temperature sensor 19. At this time, during the use of the device, when the temperature sensor 19 detects that the temperature of the device is higher than the set range during use, the controller 20 will control the fan 4 to pull the external wind through the filter 5 for filtration, and then discharge it through the air holes on the outside of the fixed tube 6 and the adapter tube 7, so as to blow it to the inclined fins 18. At this time, the rotating ring 11 will continuously drive the annularly distributed fins 18 to rotate to disturb the heat dissipation gas, and then the heat dissipation wind after disturbance is blown to the wireless charging PCBA1 for heat dissipation. Finally, when it is discharged, efficient heat dissipation of the device is achieved, thereby ensuring the service life of the device.
