[0032] An integrated underwater electric propulsion device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 An integrated underwater electric propulsion device according to an embodiment of the utility model includes an electric propeller and a control box.

[0034] The electric propeller includes a housing 100 and a motor body 110 disposed on the housing 100 , and the motor body 110 is used to output rotational power.

[0035] It should be noted that the motor body 110 has an output shaft, and the output shaft is provided with a propeller, so that the electric propulsion device can propel the surfboard to travel.

[0036] The electric propeller is a prior art. Please refer to the patent named "A propeller-shaft integrated propulsion device" and the patent number 2022227482597, which will not be described here.

[0037] The control box includes a box body 120 and an end cover 130 connected to the box body 120. Figure 1 and Figure 2 A control circuit board 140 is installed in the box body 120 , and the end cover 130 is sealed and connected to the housing 100 .

[0038] Therefore, the end cover 130 is sealed and connected to the outer shell 100, so that the electric propulsion device has a waterproof function, which prevents water from entering the inner part of the outer shell 100 and damaging the motor body 110. At the same time, the electric propulsion device and the control box are connected to form a whole by the end cover 130, which makes the structure of the electric propulsion device more compact, greatly reduces the volume of the electric propulsion device, and makes it convenient to store and carry.

[0039] Furthermore, the end cover 130 is provided with a wiring channel 150 connecting the inner cavity of the shell 100 and the inner cavity of the box body 120. The wiring channel 150 is used to arrange connecting wires connecting the control circuit board 140 and the motor body 110. Sealant is injected into the box body 120 to encapsulate the control circuit board 140.

[0040] Therefore, the wiring channel 150 connects the inner cavity of the shell 100 and the inner cavity of the box body 120, and the connecting wires between the control circuit board 140 and the motor body 110 can be arranged in the wiring channel 150 to avoid the connecting wires being exposed to the outside in a messy manner, so that the electric propulsion device and the control box can be set as one piece, and the electric propulsion device is more convenient to install on the surfboard. In addition, sealant is injected into the box body 120. The sealant can be epoxy resin glue to encapsulate the control circuit board 140. The components of the control circuit board 140 are not easy to loosen, which avoids water loss at the control circuit board 140 and the wiring points, making the control box effectively waterproof.

[0041] In some embodiments of the present invention, the end cover 130 has a support seat 290 , and the support seat 290 is provided with a support hole. The support seat 290 is rotatably connected to the output shaft of the motor body 110 through the support hole.

[0042] Therefore, there is no need to separately provide the support seat 290, which is conducive to making the electric propeller structure more compact.

[0043] In some embodiments of the present invention, the end cover 130 has a circular plate 270 , the outer circumference of the circular plate 270 is matched with the inner side of the housing 100 , and a sealing ring 280 is provided between the outer circumference of the circular plate 270 and the inner side of the housing 100 .

[0044] Therefore, water is prevented from entering the interior of the housing 100 from between the housing 100 and the end cover 130 , so that the motor body 110 has good sealing performance.

[0045] In some embodiments of the present invention, the box body 120 is formed with a receiving cavity 160 and a glue injection cavity 170 that are interconnected. The receiving cavity 160 is used to receive the control circuit board 140, and the glue injection cavity 170 is used to inject sealant.

[0046] By providing the storage cavity 160 and the injection cavity 170 , the installation position of the control circuit board 140 and the position for injecting the sealant can be defined, so that the installation of the control circuit board 140 is convenient and there is enough space for injecting the sealant.

[0047] In a further embodiment of the present invention, referring to Figure 2 and Figure 3 A mounting hole 180 is provided on the side wall of the box body 120. The mounting hole 180 is located on the side of the storage cavity 160 away from the injection cavity 170. The mounting hole 180 is used to accommodate the control circuit board 140 to pass through. The control circuit board 140 is provided with a connecting plate 190. The box body 120 is connected to a substrate 200 that covers the mounting hole 180, and the connecting plate 190 is arranged on the substrate 200.

[0048] It can be understood that the control circuit board 140 is first installed on the substrate 200 through the connecting plate 190, and then the control circuit board 140 is allowed to enter the storage cavity 160 through the mounting hole 180. Then, the substrate 200 and the box body 120 are connected and fixed, and the substrate 200 can cover the mounting hole 180 to prevent the sealant from flowing out.

[0049] In a further embodiment of the present invention, a connecting frame 220 is formed inside the box body 120 , and the connecting frame 220 is provided with a glue flow channel 300 connecting the storage cavity 160 and the glue injection cavity 170 .

[0050] Therefore, the connecting frame 220 can improve the internal structural strength of the box body 120 and prevent the box body 120 from being deformed. At the same time, the sealant is injected from the injection cavity 170 and enters the storage cavity 160 through the glue flow channel 300, so that the sealant seals the control circuit board 140.

[0051] In a further embodiment of the present invention, a wire outlet through hole 230 is disposed on the side wall of the box body 120 , and the wire outlet through hole 230 is located on a side of the glue injection cavity 170 away from the storage cavity 160 .

[0052] Therefore, the sealant can quickly flow to the wire outlet hole to seal the wires led out of the control circuit board 140, so that the wire outlet hole is well sealed and the sealing performance is improved.

[0053] In a further embodiment of the present invention, referring to Figure 4The control circuit board 140 is provided with a connecting column 240, and the connecting frame 220 is provided with a connecting hole 250 through which the connecting column 240 extends.

[0054] It is understandable that the connection column 240 extends into the glue injection cavity 170 so that the sealant can connect and fix the connection column 240 and the connection frame 220, so that the control circuit board 140 is not easy to loosen.

[0055] In a further embodiment of the present invention, referring to Figure 5 The connecting frame 220 is provided with a U-shaped connecting rib 260, and the connecting rib 260 extends along the outer side of the connecting column 240, thereby further improving the strength of the connecting frame 220, so that the connecting frame 220 is tightly connected with the sealant.

[0056] In a further embodiment of the present invention, the box body 120 is provided with a detachable cover plate 210, which is located on the side of the injection cavity 170 away from the storage cavity 160 and is used to form an inner wall of the injection cavity 170, thereby preventing the sealant from being exposed to the outside.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0058] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
