[0090] The thermal conductivity of the graphite heat-spreading film is greater than 7 W / m·K. One side of the second heat dissipation structure 9 is bonded to the surface of the high-power device by GD-414 adhesive.

[0091] Example 2

[0092] A structural design method for a wireless energy transmission device capable of withstanding high atmospheric pressure, such as Figures 1-2 As shown, this method utilizes sealing rings, limiting bosses, limiting grooves, limiting pins, limiting screws, graphite heat-dissipating films, carbon plates and other measures to complete the high atmospheric pressure resistance and thermal design of the wireless energy transmission and communication device, ensuring that the equipment can still work normally at high atmospheric pressure.

[0093] Step 1: Use sealing ring to ensure the sealing between modules

[0094] Sealing ring 42 Figure 4 As shown, according to the shape and weight of the primary and secondary devices, a sealing ring 42 with a diameter of 3.55mm is designed, and the rubber material is selected as damping rubber 6103-1. In order to ensure the sealing effect of the sealing ring 42, the compression rate of the sealing ring 42 needs to be between 17.5% and 18.5%, so the size of the sealing ring installation groove 41 is as follows: Figure 3 As shown, the depth is 2.75 (0, +0.05) mm, the groove width is 5 (0, +0.15) mm, the roughness of the sealing ring mounting groove 41 and the mating surface is 1.6 mm, the groove bottom radius is R0.5 mm, and the groove edge radius is R0.2 mm.

[0095] Step 2: Design the limiting boss and limiting groove

[0096] On the basis of placing the sealing ring, a limiting boss 51 and a limiting groove 52 are designed between the upper cover plate and each module, such as Figure 5 As shown, a sealing ring is placed in the groove 52, the limiting groove 52 has a width of 5 (0, +0.15) mm and a depth of 5.35 (0, +0.05) mm, and the limiting boss 51 has a width of 4.6±0.05 mm and a height of 2.6±0.05 mm, which ensures the sealing and atmospheric pressure resistance between the modules of the primary side device and the secondary side device.

[0097] A limiting boss 51 and a limiting groove 52 are also designed between the primary side device, the secondary side device and the mounting plate. The size is consistent with the primary side and the secondary side device itself to ensure the sealing and atmospheric pressure resistance between the primary side device, the secondary side device and the mounting plate. Figure 6 shown.

[0098] Step 3: Design the limit pins and limit holes

[0099] This wireless energy transmission and communication device requires that the primary and secondary devices have a positional offset adaptability of ±2mm and an angular tolerance range of ≥±2°, ensuring that the primary and secondary devices are properly aligned. If the primary and secondary devices are fixed separately to the mounting plate, installation tolerances can make it difficult to align them perfectly after installation, impacting wireless signal transmission. Therefore, a stop pin 61 and a stop hole 62 are designed on the primary and secondary devices, respectively, and the pin and hole are aligned in the hollow space of the mounting plate, ensuring installation accuracy and smooth wireless transmission.

[0100] A limit pin 61 is designed at the bottom of the primary device, and a limit hole 62 is designed at the bottom of the secondary device. During installation, the secondary device is first installed on the mounting plate, and then the primary device is installed. When installing the primary device, the limit pin 61 and the limit hole 62 can be used to ensure that the primary and secondary devices are aligned, thereby improving the ability to resist atmospheric pressure and ensuring the wireless energy transmission effect. Figure 7a 、 7b shown.

[0101] Step 4: Design the limit screws

[0102] The primary and secondary side devices of this wireless energy transmission and communication device have three layers of printed circuit boards, and the electrical performance is transmitted between the printed circuit boards through the RM342 series electrical connector. Due to the processing tolerances of the shell and printed circuit boards, the RM342 may not be aligned when plugged in. The misalignment of the socket will cause the RM342 pins to be stressed, resulting in signal instability when subjected to external force. Figure 8 The design of the upper limit screw 71 and the lower limit screw 72 can solve this problem. Figures 9a-9c , 10a~10c design, the middle section of the limit screw is a 2.1mm×2.1mm square area, which is used to limit the inner wall of the RM342 socket to prevent the screw from rotating. There is a second cylindrical section 715 with a diameter of 1.2 below the upper limit screw 71, which is used to position it with the mounting hole 725 with a diameter of 1.2 of the lower limit screw 72 during installation. The limit screw positioning ensures that the RM342 pin is not subjected to force.

[0103] Step 5 Design high thermal conductivity carbon plate thermal boss

[0104] The primary and secondary side devices of the wireless energy transmission and communication device have high-power devices in the uppermost layer. In order to ensure that the heat of the high-power devices is quickly conducted out, the upper cover plate is made of high-thermal-conductivity carbon plate (the thermal conductivity coefficient is 3 times that of aluminum), and a heat-conducting boss 82 is designed on the upper cover plate 81. See Figure 11 , and the heat dissipation of the high-power devices is completed by cooperating with the flexible heat-conducting pad 83. The heat dissipation path is shown in Figure 12 . The flexible heat-conducting pad 83 is 1mm above the high-power devices, the heat-conducting boss 82 is above the flexible heat-conducting pad 83, the heat of the high-power devices is conducted to the heat-conducting boss 82 through the flexible heat-conducting pad 83, and then is conducted to the device shell through the heat-conducting boss 82.

[0105] Step 6: Designing a graphite heat film

[0106] The primary and secondary side devices of the wireless energy transmission and communication device also have high-power devices in the middle layer and the lower layer, but the middle layer and the lower layer do not have cover plates, so they cannot be cooled by designing heat-conducting bosses, but they can be cooled by designing a second heat dissipation structure 9. As shown in Figure 13 , the second heat dissipation structure 9 has a thermal conductivity greater than 7W / m.k and can be folded into an L shape. One end of the second heat dissipation structure 9 is glued to the top of the high-power device by GD-414, the other end is fixed to the nearby metal shell by a pressing plate after being folded into an L shape, and the heat of the high-power device can be conducted to the device shell through the second heat dissipation structure 9, preventing the temperature of the high-power device from being too high to affect use and ensuring the normal operation of the device.

Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
