[0030] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0031] like Figures 1 to 3As shown, an underwater thruster 10 includes a bottom shell 100, a snap-fit ​​shell 200, and a snap-fit ​​component 300. The bottom shell 100 has a first shell groove 110, and a propeller 400 is provided at one end of the first shell groove 110. The snap-fit ​​shell 200 has a second shell groove 210, and one end of the snap-fit ​​shell 200 is rotatably mounted on the bottom shell 100. The snap-fit ​​component 300 is provided on one of the bottom shell 100 and the snap-fit ​​shell 200. When the snap-fit ​​shell 200 is engaged with the bottom shell 100, the snap-fit ​​component 300 engages with the other of the bottom shell 100 and the snap-fit ​​shell 200. The first shell groove 110 and the second shell groove 210 together form a battery compartment for accommodating a battery.

[0032] It should be noted that both the bottom shell 100 and the snap-fit ​​shell 200 are semi-cylindrical thin-shell structures, and both the first shell groove 110 and the second shell groove 210 are semi-cylindrical recess structures. The propeller 400 is fixedly installed in the first shell groove 110. The propeller 400 is a motor-driven blade structure. Since the propeller 400 is a common structure in the prior art, it will not be described in detail here. Furthermore, one end of the snap-fit ​​shell 200 is rotatably connected to the end of the bottom shell 100 near the propeller 400, so that the snap-fit ​​shell 200 can be snapped or opened relative to the bottom shell 100. When the snap-fit ​​shell 200 is snapped relative to the bottom shell 100, under the action of the snap fastener 300, the snap-fit ​​shell 200 and the bottom shell 100 are stably snapped and fixed together. At this time, the second shell groove 210 and the first shell groove 110 will close together to form a battery compartment. It should be noted that the snap fastener 300 can be installed on either the bottom shell 100 or the snap-fit ​​shell 200. When the latching member 300 is installed on the bottom shell 100, it is used to engage and fix with the casing 200. For ease of description, this application uses the latching member 300 installed on the casing 200 and engaged and fixed with the bottom shell 100 as a specific embodiment for illustration. Thus, the casing 200 can be quickly opened using the latching member 300, and the battery can be installed in or removed from the battery compartment. The latching member 300 can then be used to secure the casing 200 to the bottom shell 100, thereby enabling quick battery replacement.

[0033] like Figure 3 and Figure 4 As shown, in one embodiment, the fastener 300 includes a fastener base 310, a fastener block 320, and an elastic member 330. The fastener base 310 is disposed on one of the bottom shell 100 and the fastener shell 200. The fastener block 320 is slidably disposed on the fastener base 310. The elastic member 330 abuts against the fastener base 310 and the fastener block 320 respectively. The elastic member 330 is used to push the fastener block 320 so that a part of the structure of the fastener block 320 extends out from the fastener base 310 to engage with the other of the bottom shell 100 and the fastener shell 200.

[0034] It should be noted that the locking block 320 can slide relative to the locking seat 310. The two ends of the elastic member 330 abut against the locking block 320 and the locking seat 310 respectively. The elastic member 330 is used to push the locking block 320, allowing a portion of the structure of the locking block 320 to extend from one side of the locking seat 310. Furthermore, when the locking seat 310 is mounted on the bottom shell 100, the locking block 320 is used to engage with the snap-fit ​​shell 200; when the locking seat 310 is mounted on the snap-fit ​​shell 200, the locking block 320 is used to engage with the bottom shell 100. Thus, when the snap-fit ​​shell 200 and the bottom shell 100 are engaged, they can be secured by the snap-fit ​​member 300.

[0035] like Figure 2 and Figure 4 As shown, in one embodiment, the locking block 320 includes a base block 321, a pressing block 322, and a locking post 323. The pressing block 322 and the locking post 323 are both disposed on the base block 321. The locking post 323 passes through the locking seat 310. The elastic member 330 abuts against the base block 321. The bottom shell 100 / fastening shell 200 is provided with a locking hole 220. When the fastening shell 200 and the bottom shell 100 are fastened together, the elastic member 330 pushes the locking post 323 to insert into the locking hole 220.

[0036] It should be noted that the pressing block 322 and the locking pin 323 are both located on the same side of the bottom block 321, and there is a gap between the locking pin 323 and the pressing block 322. In one embodiment, there are two locking pins 323, which are located on both sides of the pressing block 322. Both locking pins 323 pass through the locking seat 310, so that the locking block 320 is slidably installed relative to the locking seat 310. The elastic member 330 pushes the bottom block 321, so that the locking pin 323 maintains the tendency to extend from one side of the locking seat 310. Thus, when the locking seat 310 is installed on the bottom shell 100, the snap-fit ​​shell 200 has a locking hole 220 so that the locking pin 323 can be inserted into the locking hole 220, so that the snap-fit ​​shell 200 is snapped and fixed to the bottom shell 100. When the card holder 310 is installed on the snap-fit ​​housing 200, a snap-fit ​​hole 220 is provided on the bottom housing 100 so that the snap-fit ​​post 323 can be inserted into the snap-fit ​​hole 220, thereby snapping and fixing the snap-fit ​​housing 200 and the bottom housing 100 together. This application illustrates an embodiment where the card holder 310 is installed on the snap-fit ​​housing 200, and a snap-fit ​​hole 220 is provided on the bottom housing 100.

[0037] like Figure 4 As shown, in one embodiment, the card holder 310 includes a base plate 311 and a buckle 312. The buckle 312 is fastened to the base plate 311, the card block 320 is slidably disposed on the buckle 312, and the elastic member 330 abuts against the base plate 311.

[0038] It should be noted that the seat plate 311 is fixedly installed to the buckle 312 by screws, so that the locking block 320 and the elastic element 330 are both located inside the buckle 312. The elastic element 330 abuts against the seat plate 311, so that the elastic element 330 pushes the bottom block 321, and the locking post 323 extends out from the side of the buckle 312 away from the seat plate 311.

[0039] In one embodiment, two fasteners 300 are provided, and the two fasteners 300 are respectively located on opposite sides of the bottom shell 100 or the snap-fit ​​shell 200. Specifically, when the two fasteners 300 are installed on the bottom shell 100, the two fasteners 300 are located on opposite sides of the inner sidewall of the first shell groove 110 of the bottom shell 100. When the two fasteners 300 are installed on the snap-fit ​​shell 200, the two fasteners 300 are located on opposite sides of the second shell groove 210 of the snap-fit ​​shell 200.

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, the underwater thruster 10 further includes an end cap 500, which is fastened to the end of the bottom shell 100 and the end cap 200 away from the propeller 400.

[0041] It should be noted that, to further improve the reliability of the connection between the snap-fit ​​shell 200 and the bottom shell 100, after the snap-fit ​​shell 200 and the bottom shell 100 are snapped together, the ends of the snap-fit ​​shell 200 away from the propeller 400 and the ends of the bottom shell 100 away from the propeller 400 are flush to form a conical structure. Then, the end cap 500 is snapped onto the flush end faces of the snap-fit ​​shell 200 and the bottom shell 100. This further secures the snap-fit ​​shell 200 and the bottom shell 100. In one embodiment, the end cap 500 is screwed to the snap-fit ​​shell 200 and the bottom shell 100. For example, an internal thread is provided on the inner wall of the end cap 500, and an external thread is provided on the outer wall of the end of the snap-fit ​​shell 200 and the bottom shell 100 away from the propeller 400, so that the end cap 500 can be screwed and fixed to the snap-fit ​​shell 200 and the bottom shell 100.

[0042] like Figure 5 As shown, in one embodiment, a first magnetic block 600 is provided on the end of the snap shell 200 and the bottom shell 100 away from the propeller 400, and a second magnetic block 700 is provided on the end cover 500. The first magnetic block 600 is used to magnetically attract the second magnetic block 700 so that the end cover 500 is snapped onto the end of the bottom shell 100 and the snap shell 200 away from the propeller 400.

[0043] It should be noted that this embodiment shows another fixing structure for the end cap 500. Specifically, a first magnetic block 600 is installed on the end of the bottom shell 100 and the snap shell 200 away from the propeller 400, and a second magnetic block 700 is installed on the end cap 500. The first magnetic block 600 is used to magnetically fix the second magnetic block 700, so that the end cap 500 is snapped onto the end position of the snap shell 200 and the bottom shell 100. In this way, the fastening reliability between the snap shell 200 and the bottom shell 100 is enhanced.

[0044] In one embodiment, multiple first magnetic blocks 600 are provided, each first magnetic block 600 is circumferentially arranged on the end of the bottom shell 100 and the buckle shell 200 away from the propeller 400, and multiple second magnetic blocks 700 are provided, each second magnetic block 700 is circumferentially arranged on the end cover 500, and each first magnetic block 600 is used to magnetically attract each second magnetic block 700 in a one-to-one correspondence.

[0045] It should be noted that, in order to improve the reliability of the fastening between the end cap 500 and the snap shell 200 and the bottom shell 100, multiple first magnetic blocks 600 are installed to magnetically fix multiple second magnetic blocks 700 respectively, so that the end cap 500 is reliably magnetically fixed at the end position of the bottom shell 100 and the snap shell 200.

[0046] like Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, the bottom shell 100 is further provided with two buoyancy parts 800, which are located on opposite sides of the bottom shell 100.

[0047] It should be noted that, since the underwater thruster 10 has a certain weight, in order to improve the buoyancy of the underwater thruster 10 underwater, a buoyancy section 800 is provided on each of the opposite sides of the outer wall of the bottom shell 100. Specifically, the buoyancy section 800 and the bottom shell 100 are integrally formed.

[0048] Furthermore, such as Figure 6 As shown, in one embodiment, a buoyancy groove 810 is provided in the buoyancy part 800, and a buoyancy block 900 is provided in the buoyancy groove 810.

[0049] It should be noted that the buoyancy tank 810 and the first shell tank 110 are independent spaces. A buoyancy block 900, for example made of foam board, is installed inside the buoyancy tank 810, thus effectively increasing the buoyancy of the underwater thruster 10.

[0050] like Figure 1 As shown, in one embodiment, a pressure strip 1100 is provided on one end of the second shell groove 210 near the propeller 400. When the snap shell 200 is snapped into the bottom shell 100, the pressure strip 1100 presses against the propeller 400.

[0051] It should be noted that, for example, the pressure strip 1100 is made of soft rubber. In this way, after the propeller 400 is installed inside the bottom shell 100, when the buckle 200 is fastened and fixed to the bottom shell 100, the pressure strip 1100 is pressed against the propeller 400, which can reliably fix the buckle 200 relative to the bottom shell 100 without the problem of loosening.

[0052] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
