[0030] In the prior art, after the wireless charging transmitting device is installed, the top thereof is exposed outside, and the remaining part is buried underground. After a rainy day, water may enter the shell 1 of the wireless charging transmitting device, and when the water entering the shell 1 contacts the circuit board 2, the water may form a conductive path between the lines or pins of the circuit, thereby causing a short circuit, thereby affecting the normal work of the wireless charging transmitting device.

[0031] In order to solve the above problems, the utility model provides a kind of wireless charging transmitting device, including shell 1, circuit board 2 and potting glue 3;The inside of the shell 1 is equipped with accommodating cavity 13;Accommodating cavity 13 is equipped with the first slot structure 14 of one end opening;The circuit board 2 is located in the first slot structure 14;The potting glue 3 is filled in the first slot structure 14, and after solidification, the circuit board 2 is wrapped.

[0032] Specifically, as shown in Figures 1 to 4 The shell 1 can be cylindrical, square or other irregular shape, which is not limited here and is determined according to actual needs. As shown in Figure 1 The shell 1 is similar to a cylinder as a whole, and is provided with an accommodating cavity 13 inside, and the depth of the accommodating cavity 13 is generally between 10 cm and 18 cm. The center of the accommodating cavity 13 is provided with a first slot structure 14 of one end opening, and the depth of the first slot structure 14 is generally between 6 cm and 14 cm. The depth of the accommodating cavity 13 is deeper, and the depth of the first slot structure 14 is deeper. The circuit board 2 is located at the bottom of the first slot structure 14, and the potting glue 3 is filled in the first slot structure 14 and wrapped around the circuit board 2 after solidification.

[0033] In this embodiment, the circuit board 2 is first placed in the first groove structure 14, and then an appropriate amount of potting compound 3 is poured into the first groove structure 14 until the potting compound 3 immerses the circuit board 2. After the potting compound 3 solidifies, it can wrap the circuit board 2, thereby isolating the circuit board 2 from the outside world, thus improving the problem that the circuit board 2 is affected by water and thus affects the normal operation of the wireless charging transmitter.

[0034] Optionally, the wireless charging transmitter further includes a cylindrical member 4, one end of which is connected to the inner wall of the accommodating cavity 13 along the through direction; the inner wall of the cylindrical member 4 and the inner wall of the accommodating cavity 13 together form the first groove structure 14.

[0035] Specifically, the cross-sectional shape of the cylindrical component 4 can be a circular ring or a square ring. For example... Figure 3 , 4 As shown, the cross-sectional shape of the cylindrical member 4 can be a square ring. One end of the cylindrical member 4 along the through direction (that is, the bottom end) is connected to the bottom wall of the accommodating cavity 13. The connection method between the two includes, but is not limited to, bonding, screw connection or welding. After the cylindrical member 4 is installed, the inner wall of the cylindrical member 4 and the bottom wall of the accommodating cavity 13 together form the first groove structure 14.

[0036] In this embodiment, the first groove structure 14 is formed by the inner wall of the cylindrical part 4 and the inner wall of the accommodating cavity 13. Therefore, during the production process, without significantly changing the inner wall of the accommodating cavity 13, the depth of the first groove structure 14 can be customized by selecting the thickness of the cylindrical part 4. At the same time, the cylindrical part 4 can be produced as a separate part first and then assembled, which can reduce the complexity of the mold.

[0037] Furthermore, in order to reduce the risk of injury to the human body due to the sharp edges of the cylindrical component 4 during processing or installation, the edges of the cylindrical component 4 are provided with a rounded corner structure, the diameter of which ranges from 1cm to 2cm.

[0038] Optionally, the first groove structure 14 is formed by the inner surface of the accommodating cavity 13 being recessed towards the outer side of the housing 1.

[0039] Specifically, the first groove structure 14 is formed by the inner bottom surface of the accommodating cavity 13 recessed towards the outer side of the shell 1. Therefore, the bottom of the accommodating cavity 13 needs to have a certain thickness in order to provide space for processing the first groove structure 14. In this way, the first groove structure 14 can be integrally manufactured when processing the shell 1, which can effectively reduce processing time.

[0040] Furthermore, after the first groove structure 14 is processed, in order to disperse the stress at the junction of the bottom wall of the accommodating cavity 13 and the first groove structure 14, a rounded corner structure is provided at the junction of the bottom wall of the accommodating cavity 13 and the first groove structure 14, and the diameter of the rounded corner structure ranges from 1cm to 2cm.

[0041] Optionally, one end of the cured potting glue 3 is flush with the opening of the first groove structure 14.

[0042] Specifically, as shown in Figure 3 、 5 , after the potting glue 3 is cured, the upper end surface of the potting glue 3 is flush with the opening of the first groove structure 14, that is, the upper end surface of the potting glue 3 is at the same horizontal plane as the opening of the first groove structure 14. In this way, when water enters the accommodation cavity 13, since the upper end surface of the potting glue 3 is flush with the opening of the first groove structure 14, there is no space between the two to accommodate moisture, which can reduce the probability of moisture entering the first groove structure 14 through the gap between the two.

[0043] It should be noted that although the above embodiment provides a way in which one end of the cured potting glue 3 is flush with the opening of the first groove structure 14, it does not exclude an embodiment in which one end of the cured potting glue 3 is located inside the first groove structure 14.

[0044] Optionally, the material of the potting glue 3 includes silicone or epoxy resin.

[0047] Specifically, the shell 1 includes two parts, as shown in Figure 1 、 3 , the shell 1 includes a mounting seat 12 and a cover plate 11, wherein the cover plate 11 is disc-shaped and is used to cooperate with the wireless receiving module of the electric bicycle; the mounting seat 12 is cylindrical as a whole and is provided with a second groove structure 121 with an upper end open; the first groove structure 14 is arranged in the first groove structure 14; the cover plate 11 is arranged at the opening of the second groove structure 121 to open or close the opening of the second groove structure 121; when the cover plate 11 closes the opening of the second groove structure 121, the cover plate 11 and the second groove structure 121 form the accommodation cavity 13.

[0048] In this optional embodiment, when assembling the wireless charging transmitting device, the shell 1 is divided into two parts, which facilitates the pouring of glue in the first groove structure 14, thereby achieving waterproofing of the circuit board 2.

[0049] Optionally, the wireless charging transmitting device further comprises a waterproof member 5, and the connecting portion of the mounting seat 12 and the cover plate 11 is provided with the waterproof member 5.
