[0023] See also Figure 1 , shown is a wireless rechargeable underwater camera assembly according to an embodiment of the utility model, comprising a wireless rechargeable underwater camera 1 and a charging base 2, wherein the charging base 2 is used to charge the wireless rechargeable underwater camera 1.

[0024] Combination Figure 2 and Figure 3 As shown, the wireless charging underwater camera 1 includes a camera housing 11, and a bracket 16, a lens assembly 12, a first control circuit board 13 and a battery assembly contained in the housing 11. The bracket 16 includes a first bracket portion 161 and a second bracket portion 162 that overlap each other to form a receiving cavity. The lens assembly 12, the first control circuit board 13 and the battery assembly are sequentially installed in the receiving cavity along the axial direction of the bracket 16 to form a pre-assembled whole with the bracket 16, making the overall structure more compact and saving space.

[0025] The camera housing 11 is a semi-enclosed cavity structure with an opening 116. The camera housing 11 is in the shape of a bullet. Preferably, fins are provided on both sides of the camera housing 11. This streamlined design can reduce the resistance encountered by the wireless rechargeable underwater camera 1 when it moves underwater, and prevent the device from shaking left and right due to the impact of water flow during fishing, thereby improving the stability of fishing. When the wireless rechargeable underwater camera 1 moves in the water, the fins can ensure the stability of the wireless rechargeable underwater camera 1, and prevent the image from shaking violently during mobile shooting.

[0026] Preferably, the camera housing 11 of the wireless charging underwater camera 1 is an integrated structure. The camera housing 11 defines a receiving cavity and has a first end and a second end opposite to each other, the first end is sealed, and the second end has an opening 116. The preassembled whole is installed in the camera housing 11 through the opening 116, and is threadedly connected to the bracket through a screw (preferably an exhaust screw 17) passing through the first end of the camera housing 11; wherein, the lens assembly 12 is arranged adjacent to the opening 116 of the second end, and a lens 111 is sealed at the opening 116 of the second end to seal the receiving cavity. The lens 111 is sealedly connected to the camera housing 11, and the wireless charging method omits the charging interface or slot, avoiding the possibility of water seepage. The only screw hole is locked and sealed by the exhaust screw 17, so that a water vapor sealed space is formed in the camera housing 11. When the ambient temperature is high, the air in the camera housing 11 expands, and the exhaust screw 17 can be used to exhaust air to balance the internal and external air pressures to avoid the lens 111 being flushed due to air expansion.

[0027] Preferably, the lens 111 is connected with the bracket 16 by snapping, and the lens 111 is provided with a plurality of snappings 117 along the circumferential direction, and the bracket 16 is correspondingly provided with snapping holes 163, and the snappings 117 are correspondingly snapped into the snapping holes 163. After assembly, the lens 111 and the bracket 16 are connected as an integral structure, and the lens 111 cannot be removed without loosening the exhaust screw 17. If the whole machine needs to be disassembled for maintenance, the lens 111 can only be pulled out by unscrewing the exhaust screw 17, and the bracket 16 and the lens assembly 12, the first control circuit board 13 and the battery assembly installed therein can be pulled out.

[0028] As an alternative, the lens 111 and the bracket 16 can be connected by threaded connection or other detachable methods. Similarly, the lens 111 can also be detachably connected to the camera housing 11 (rather than the bracket 16), so that the installation of the lens 111 and the sealing of the receiving cavity can also be achieved.

[0029] A magnetic switch 18 is slidably disposed on the outer side of the camera housing 11, and a Hall element 133 and a switch circuit are disposed on the first control circuit board 13. The magnetic switch 18 can be slidably switched between an open position and a closed position, and the Hall element 133 is used to sense the position change of the magnetic switch 18. The switch circuit is turned on or off according to the position change of the magnetic switch 18 sensed by the Hall element 133.

[0030] The first control circuit board 13 includes a main control circuit board 131 and an auxiliary circuit board 132 which are arranged in parallel and spaced apart along the radial direction of the bracket. The lens assembly 12 and the Hall element 133 are electrically connected to the main control circuit board 131, and the battery assembly is electrically connected to the auxiliary circuit board 132. The main control circuit board 131 and the auxiliary circuit board 132 are arranged in parallel and spaced apart along the radial direction, which can reduce space and make the product more compact and small.

[0031] Preferably, a wireless communication module is integrated on the auxiliary circuit board 132, and the wireless communication module is one of Bluetooth, WiFi, and GPRS. The wireless communication module is used to realize operations such as recording and taking pictures of the wireless rechargeable underwater camera 1; the battery assembly includes a charging receiving coil 14 and a battery 15, and the battery 15 and the charging receiving coil 14 are electrically connected to the auxiliary circuit board 132 respectively, so that the charging receiving coil 14 can charge the battery 15.

[0032] In order to prevent water seepage between the camera housing 11 and the lens 111, and between the camera housing 11 and the exhaust screw 17, and to improve the waterproof performance of the integrated housing, a first sealing member 112 is provided between the inner wall of the first end of the camera housing 11 and the bracket 16, and the exhaust screw 17 sequentially penetrates the camera housing 11 and the first sealing member 112 and is then screwed to the bracket; multiple circles of sealing rings 114 are also sleeved around the exhaust screw 17; and a second sealing member 113 is provided between the lens 111 and the camera housing 11. The first sealing member 112 and the second sealing member 113 can be sealing rings 114, sealing pads, etc. of different shapes and specifications.

[0033] The outer wall of the camera housing 11 is also provided with a connecting piece 115, which is a threading plate for connecting with a fishing line to realize monitoring of the underwater environment when fishing.
