[0035] The embodiment of the present utility model provides a wireless charging device, as Figures 1 to 5 shown, the wireless charging device includes a body 1, a first wireless charging board 2, a damping connection piece 3 and a wire 4; a main control circuit board 19 is arranged in the body 1, and a first wireless charging module is arranged in the first wireless charging board 2; the first wireless charging board 2 is rotatably mounted on one side of the top of the body 1 through the damping connection piece 3, and the first wireless charging board 2 can cover the top of the body 1 and stand up from the top of the body 1. A wiring groove opening 31 is formed in the damping connection piece 3, the wire 4 is electrically connected to the first wireless charging module, and after being led out from the first wireless charging board 2, it is introduced into the body 1 from the position of the damping connection piece 3 and electrically connected to the main control circuit board 19; a part of the wire 4 is embedded in the wiring groove opening 31.

[0036] The first wireless charging board 2 of the wireless charging device of the present utility model is rotatably mounted on the top of the body 1 through the damping connection piece 3. Among them, a wiring groove opening 31 is formed in the damping connection piece 3. When the wire 4 for connecting the first wireless charging board 2 is routed from the first wireless charging board 2 to the inside of the body 1 and electrically connected to the main control circuit board 19, it can pass through the wiring groove opening 31, that is, a wiring position for the wire 4 is provided at the connection between the first wireless charging board 2 and the body 1. A part of the wire 4 is embedded in the wiring groove opening 31 to realize its routing, and the damping connection piece 3 can also hide the wire 4 to a certain extent, facilitating the routing of the wire 4 from the first wireless charging board 2 to the inside of the body 1 and reducing the difficulty of routing the wire 4.

[0037] Specifically, the first wireless charging board 2 can charge electronic devices such as mobile phones. After the wireless charging device is connected to the power supply through the power interface 191, the first wireless charging board 2 stands up from the top of the main body 1, and the mobile phone can be abutted against the side of the first wireless charging board 2 facing away from the top of the main body 1 for wireless charging. The power interface 191 is arranged on the side of the main body 1 and can be a Type-c port. An expansion interface 192 can be further arranged on the side of the main body 1. The expansion interface 192 can be connected to a charging cable or other wireless charging devices for wireless charging. The expansion interface can be a Type-c port. The first wireless charging module can be a magnetic wireless charging module, which can adopt a conventional magnetic wireless charging module and will not be elaborated here. When not in use, the first wireless charging board 2 can be rotated and closed on the top of the main body 1 to achieve folding storage. Of course, in the folded storage state, the first wireless charging board 2 can also perform wireless charging.

[0038] As Figure 6 shown, an installation shaft 11 is installed near the top of the main body 1. The damping connection piece 3 includes two damping connection arms 32 arranged side by side. The two damping connection arms 32 are sleeved on the installation shaft 11 in a damping manner; the two damping connection arms 32 are arranged at intervals to form a wire routing slot 31. In this solution, the damping connection with the installation shaft 11 is realized by arranging two side-by-side damping connection arms 32, and at the same time, the wire routing slot 31 is formed by the interval arrangement of the two damping connection arms 32. The two damping connection arms 32 are sleeved on the installation shaft 11 and are pre-tightened to a certain extent, so that there is a certain damping between the connection of the installation shaft 11 and the damping connection arms 32. After the first wireless charging board 2 stands up, it can be maintained at the erected angle under the action of the damping force. The installation shaft 11 can be fixedly installed on the following first partition 14 by screws 5.

[0039] Furthermore, the damping connection piece 3 further includes an installation sub-piece 33. The installation sub-piece 33 is connected to the two damping connection arms 32, and the installation sub-piece 33 is installed on the side of the first wireless charging board 2 facing the top of the main body 1; the connection between the installation sub-piece 33 and the two damping connection arms 32 is bent so that the installation sub-piece 33 and the two damping connection arms 32 are staggered from each other. The connection between the installation sub-piece 33 and the two damping connection arms 32 is staggered by bending, which can increase the rotation opening angle of the first wireless charging board 2.

[0040] On one side of the first wireless charging board 2 facing the top of the main body 1, there is an installation groove 21. A threaded hole and a limiting convex post 211 are arranged in the installation groove 21; corresponding to the threaded hole and the limiting convex post 211 on the installation sub-piece 33, there are respectively a fixing hole 331 and a limiting hole 332. The installation sub-piece 33 is embedded in the installation groove 21, the limiting convex post 211 is inserted into the limiting hole 332, and a screw 5 is threadedly installed in the threaded hole and the fixing hole 331. The installation groove 21 can limit the installation sub-piece 33, and the cooperation between the limiting convex post 211 and the limiting hole 332 can play a role in preliminary positioning during installation and limiting after installation. On this basis, the installation sub-piece 33 is finally fixed by further installing the screw 5 in the fixing hole 331 and the threaded hole. The installation sub-piece 33 and the installation groove 21 can be covered by a rubber pad 24.

[0041] Specifically, there are three limiting convex posts 211 and limiting holes 332. The three limiting convex posts 211 and limiting holes 332 are respectively arranged in an isosceles triangle to form a first isosceles triangle array; there are three threaded holes and fixing holes 331. The three threaded holes and fixing holes 331 are respectively arranged in an isosceles triangle to form a second isosceles triangle array; the first isosceles triangle array and the second isosceles triangle array are inverted with respect to each other and are arranged in an interlaced manner with each other. In this solution, the limiting convex posts 211, the limiting holes 332 are staggered with the threaded holes and the fixing holes 331. As Figure 5 and Figure 6 shown, one of the screws 5 is located between two limiting convex posts 211 and limiting holes 332, and the remaining one limiting convex post 211 and limiting hole 332 are located between the other two screws 5. In this way, on the one hand, the space of the installation sub-piece 33 and the installation groove 21 can be fully utilized, and on the other hand, the fixing effect of the installation sub-piece can be improved.

[0042] On the other hand, on one side of the first wireless charging board 2 facing the top of the main body 1, a first avoidance groove 22 is opened near the side where it is rotatably connected to the main body 1. The first avoidance groove 22 can avoid the edge of the top of the main body 1 during the rotation process, facilitating the rotation of the first wireless charging board 2. A first storage groove 12 is arranged on the top of the main body 1, and a first coordination convex surface 23 adapted to the first storage groove 12 is arranged on one side of the first wireless charging board 2 facing the top of the main body 1; when the first wireless charging board 2 covers the top of the main body 1, the first coordination convex surface 23 is embedded in the first storage groove 12. The cooperation between the first coordination convex surface 23 and the first storage groove 12 can improve the storage stability of the first wireless charging board 2. A second wireless charging module 13 is further arranged in the main body 1 near its top, and the second wireless charging module 13 is electrically connected to the main control circuit board 19. The second wireless charging module 13 can wirelessly charge electronic devices such as earphones. During charging, the earphone can be directly placed in the first storage groove 12. A charging recess 120 can be further arranged on the first storage groove 12 to facilitate the placement of the earphone.

[0043] As shown Figures 6 to 8 in FIG. 1, a first partition plate 14 is provided at the top of the main body 1. The first partition plate 14 divides the space inside the main body 1 into an upper installation cavity 15 and a lower cavity 16. The second wireless charging module 13 is installed in the upper installation cavity 15. The lower cavity 16 can increase the overall height of the main body 1 to ensure that the height of the first wireless charging board 2 is suitable for mobile phone charging. The upper installation cavity 15 provides an installation space for the second wireless charging cavity. The main control circuit board 19 is installed on one side of the lower cavity 16 close to the bottom of the main body 1, and a counterweight 17 is provided below the main control circuit board 19. The counterweight 17 can play a role in stabilizing the wireless charging device. The counterweight 17 can be an iron block.

[0044] As shown Figure 9 in FIG. 2, a first circuit board 18 electrically connected to the main control circuit board 19 is provided inside the main body 1. A status indicator light 181 is provided on the first circuit board 18; a window 110 is provided on the side surface of the main body 1 corresponding to the status indicator light 181, and the status indicator light 181 is exposed through the window 110. The status indicator light 181 has a first lighting prompt state and a second lighting prompt state; when the wireless charging device is connected to a power supply, the status indicator light 181 is in the first lighting prompt state; when the first wireless charging module or the second wireless charging module 13 performs wireless charging, the status indicator light 181 is in the second lighting prompt state. By respectively displaying the first lighting prompt state and the second lighting prompt state, the user can conveniently know the current state of the wireless charging device. Combining Figure 9 FIG. 3, the status indicator light 181 is a plurality of lamp beads, and the lamp beads respectively form two eye shapes located above and a mouth shape below. When the wireless charging device is connected to the power supply, the lamp beads in the two eye parts light up, and this is the first lighting prompt state of the status indicator light 181 at this time. The user can know from this that the wireless charging device has been connected to the power supply. When the mobile phone or the earphone is charging, while the lamp beads in the two eye parts light up, the lamp beads in the mouth part also light up. At this time, it is the second lighting prompt state of the status indicator light 181, and the user can know from this that the wireless charging device is already performing wireless charging. Specifically, a light-transmitting protection panel 130 can be installed at the window 110 for masking, and the first circuit board 18 is vertically inserted on the main control circuit board 19.
