Description

A quick-detachable underwater booster device with adjustable power-assistance direction Technical Field

[0001] The present invention relates to the field of underwater equipment, and in particular to a quick-detachable underwater boosting device with adjustable power-assisting direction. Background Art

[0002] An underwater waist booster is a tool that provides auxiliary propulsion power for underwater workers to improve their underwater movement speed and work efficiency. Among them, the waist booster is usually composed of a waist belt and a booster, and when in use, the two need to be assembled and fixed. In the prior art, the waist belt and the booster are usually locked and fixed by parts such as bolts. The use of such parts for connection requires the use of auxiliary tools such as screwdrivers during assembly and disassembly, which is particularly inconvenient for underwater equipment that needs to be disassembled and inspected regularly. In addition, the installation direction of the existing booster is fixed, and it can only adjust the direction of underwater movement, but it will affect the movement of the arms when the human body is walking or sitting on the shore, thus causing inconvenience. Summary of the Invention

[0003] In view of this, the present invention provides a quick-detachable underwater boosting device with adjustable power-assisting direction.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A quick-detachable underwater thrust-assisting device with adjustable power-assisting direction comprises a waist belt and thrust-assisting devices arranged on opposite sides of the waist belt, wherein the thrust-assisting devices are detachably connected to the waist belt via a connecting mechanism; the thrust-assisting device comprises an electrically connected power module and a power supply module, wherein the power module and the power supply module are detachably connected via a snap assembly, and there is no wiring connection between the power module and the power supply module; the connecting mechanism comprises a connecting plate, a cover plate and an adapter bracket, wherein a hollow cavity is formed between the cover plate and the connecting plate, and the adapter bracket is mounted on the hollow cavity and can rotate relative to the hollow cavity; wherein the thrust-assisting device is detachably mounted on the adapter bracket via a mounting seat.

[0006] In the above technical solution, the booster device and the belt are connected by a connecting mechanism, and the adapter bracket on the connecting mechanism is rotatable, so that the booster device can be rotated, thereby allowing the user to adjust the direction of the booster device to meet the needs of different scenarios such as underwater operations or walking on shore, thereby improving the comfort of use. In addition, the booster device and the belt, as well as the power module and the power supply module, adopt a quick-release connection method, allowing the user to quickly and easily install and remove the booster device without the need for auxiliary tools. This not only improves the convenience of use, but also helps save time and improve efficiency. At the same time, the power module and the power supply module adopt a non-wiring connection, which effectively avoids the safety hazards caused by wiring problems in the underwater environment, and also improves the waterproof performance and stability of the entire device.

[0007] Optionally, in a possible implementation, the connecting mechanism further includes a pressing piece, which is elastically and slidably installed in the hollow cavity, and a pressure rod and a limiting column are provided on the pressing piece, and the pressure rod extends to the outside of the hollow cavity, and the limiting column is located in the hollow cavity, and at least two limiting grooves are provided on the adapter bracket, and the limiting column can be inserted in different limiting grooves and can be detached from the limiting groove by sliding.

[0008] In the above technical solution, the connecting plate and adapter bracket can be connected to the waist belt and the booster device respectively. The adapter bracket can rotate freely relative to the hollow cavity, so its angle and position can be easily adjusted according to actual needs, thereby providing greater operational flexibility. In addition, the cooperation between the limit column on the pressing member and the limit slot on the adapter bracket can achieve stable locking of the mechanism at different angles. This locking mechanism is both simple and reliable, effectively preventing accidental rotation or loosening. By sliding the pressing member, the limit column can be easily disengaged from the limit slot, thereby unlocking the adapter bracket and allowing it to rotate again. This unlocking method is intuitive and easy to operate, greatly improving the user experience.

[0009] Optionally, in a possible implementation, a socket is provided in the hollow cavity, a positioning hole is provided on the socket, and the limiting column can be inserted into the limiting groove after passing through the positioning hole; the adapter bracket includes a connecting seat and an adapter plate, the adapter plate is located outside the hollow cavity, the connecting seat is provided in the socket, and the limiting groove is located on the connecting seat, and at least two of the limiting grooves are arranged at intervals along the rotation direction of the adapter bracket.

[0010] In the above technical solution, the base serves as the installation base of the adapter bracket, providing additional support and stability for the installation of the adapter bracket, effectively reducing the shaking or deformation of the adapter bracket when rotating or subjected to force; in addition, the base is provided with a positioning hole, and when the adapter bracket is installed on the base, the limiting column can pass through the limiting slot of the positioning hole in turn, so that the limiting column can always remain in the correct position without offset, so that it can be accurately inserted into the limiting slot, thereby improving the accuracy of positioning.

[0011] The adapter bracket is divided into two parts: a connecting base and an adapter plate. The connecting base is rotatably connected to the card base, so that the connecting base can rotate within the card base, and the adapter plate can be connected to the booster device, which can greatly facilitate the assembly and use of the adapter bracket; and at least two limit grooves are arranged at intervals along the rotation direction of the adapter bracket, so that when rotating the adapter bracket, you can choose to lock it at different angles, thereby meeting the flexibility in different scenarios and usage requirements.

[0012] Optionally, in a possible implementation, an arc-shaped positioning groove is provided in the card seat, and a positioning block is provided on the connecting seat, and the positioning block can abut against both ends of the arc-shaped positioning groove.

[0013] In the above technical solution, the combined use of the arc-shaped positioning groove and the positioning block allows for more precise rotation of the adapter bracket. When the adapter bracket is rotated to the desired angle, the positioning block abuts against the end of the arc-shaped positioning groove, ensuring the stability and accuracy of the adapter bracket. Furthermore, the ends of the arc-shaped positioning groove serve as the limit positions for the adapter bracket's rotation, effectively preventing excessive rotation. They also serve as signals of full rotation, ensuring accurate alignment between the limit post and the groove.

[0014] Optionally, in a possible implementation, the snap button assembly includes an inner key, an outer key and a self-locking key, the inner key rotates and is spaced apart with a first pin and a second pin, the outer key is rotatably connected to the first pin, one end of the outer key is close to the first pin, and the other end is provided with a hook; the self-locking key is elastically clamped on the inner key and is located between the first pin and the second pin, and a lock hole is also provided on the self-locking key; the inner key is rotatably installed on the power module through the second pin, the power module is provided with a card block matching the hook, the power module is provided with a hook matching the lock hole, the inner key can be locked by the hook, and the hook can be locked by the card block.

[0015] In the above technical solution, the setting of the internal key, external key and self-locking key in the snap assembly enables the power module and the power module to form a stable structure when connected; the self-locking key also enables the device to automatically lock after connection, preventing the module from being separated due to unexpected situations during use, and effectively improving the stability of the connection between modules.

[0016] To unlock the snap assembly, the self-locking key is pressed to disengage it from the lock hole. The inner key is then rotatable. The inner key is then moved closer to the first pin, causing the entire snap assembly to rotate around the second pin. This frees the hook on the outer key and allows the outer key to rotate around the first pin to unlock. Similarly, to lock the snap assembly, the outer key is first connected to the block, and then the inner key is connected to the hook.

[0017] Optionally, in a possible implementation, a slot is provided on the inner key, and the self-locking key includes a press plate, a lock plate and a limit member, the press plate is located on one side of the inner key, the lock plate is slidably clamped in the slot, the limit member is provided on the lock plate and can abut against the side wall of the slot, and the lock hole is located on the lock plate.

[0018] In the above technical solution, by providing a slot on the inner key, the self-locking key can be securely inserted and slide within the slot, thereby enhancing the stability of the connection between the self-locking key and the inner key. The locking plate can be moved within the slot by pressing the push button, making operation simple and convenient. Furthermore, a limiter is provided on the locking plate. When the locking plate is locked, the limiter effectively prevents the locking plate from sliding within the slot, thereby ensuring the locking function of the snap assembly and effectively preventing the locking plate from disengaging from the slot.

[0019] Optionally, in a possible implementation, a positioning post is further provided on the lock plate, a positioning hole matching the positioning post is provided in the slot, an elastic member is sleeved on the positioning post, and the elastic member is located between the lock plate and the inner side wall of the slot.

[0020] In the above technical solution, the positioning post and positioning hole serve to guide and limit the sliding of the lock plate, so that the lock plate can only slide back and forth in one direction. That is, when the button is pressed, the lock plate will slide and simultaneously drive the positioning post to slide in the positioning hole. This can ensure the accuracy and stability of the lock plate during the sliding process, thereby improving the unlocking or locking operation experience. The provision of the elastic member can serve as a reset function. When the lock plate moves under the action of external force and allows the lock hole to disengage from the locking member such as the hook, the elastic member can reset the lock plate to its original position, making it easier to relock the snap assembly.

[0021] Optionally, in a possible implementation, the power module includes a drive component and an electric control cabin component, and the drive component is connected to the power module via the electric control cabin component without wiring.

[0022] In the above technical solution, the setting of the electric control cabin assembly eliminates the need for cables to connect the drive assembly and the power module, making assembly simpler and faster, reducing the size and weight of the equipment, reducing electrical failures and safety hazards, and eliminating problems such as entanglement, wear and corrosion caused by cable connections, allowing the device to better adapt to various complex underwater environments.

[0023] Optionally, in a possible implementation, the driving assembly includes a duct, a driving member arranged in the duct, and a propeller connected to the output end of the driving member, the electric adjustment cabin assembly includes a cabin body, an electric adjustment board, and an adapter, the electric adjustment board is arranged in the cabin body, the driving member is provided with multiple connection ends, the cabin body is provided with multiple through holes, the through holes are nested with sealing rings, the connection ends pass through the through holes and are connected to the electric adjustment board, multiple pins are provided at both ends of the adapter, one end of the adapter is connected to the electric adjustment board, and the other end is connected to the power module.

[0024] In the above technical solution, the arrangement of the connection end, adapter, and electric adjustment board 22 allows the driver to connect to the battery without the use of cables or wires, thus avoiding problems such as cable damage and poor contact. Furthermore, a sealing ring is provided in the through-hole of the cabin, achieving a static connection between the sealing ring and the driver, reducing the chance of water seepage and improving the sealing effect of the underwater propulsion device.

[0025] Optionally, in a possible implementation, a water inlet shield is provided at the end of the duct, a water inlet grid is provided on the side of the duct, and the water inlet shield is detachably connected to the duct.

[0026] In the above technical solution, the water inlet shield protects the duct, preventing underwater impurities from entering the duct and affecting the performance of the underwater booster. Furthermore, the detachable connection between the water inlet shield and the duct allows the power module to replace only the damaged components, such as the duct, propeller, drive element, and water inlet shield, without having to discard the entire booster, significantly reducing operating costs. Furthermore, the water inlet grille on the side of the duct effectively increases the water intake of the underwater booster, facilitating propeller operation and enhancing the boosting effect.

DETAILED DESCRIPTION

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0052] Please refer to Figures 1 and 2. This embodiment provides a quick-detachable underwater thrust-boosting device with adjustable thrust direction, including a waist belt 1 and thrust-boosting devices arranged on opposite sides of the waist belt 1, the thrust-boosting devices are detachably connected to the waist belt 1 through a connecting mechanism 6; the thrust-boosting device includes an electrically connected power module and a power supply module 4, the power module and the power supply module 4 are detachably connected through a snap assembly 5, and there is no wiring connection between the power module and the power supply module 4; the connecting mechanism 6 includes a connecting plate 61, a cover plate 62 and an adapter bracket 63, the cover plate 62 is installed on the connecting plate 61, a hollow cavity is formed between the cover plate 62 and the connecting plate 61, the adapter bracket 63 is installed on the hollow cavity and can rotate relative to the hollow cavity; wherein, the thrust-boosting device is detachably mounted on the adapter bracket 63 through the mounting seat 41.

[0053] In this embodiment, the booster device and the waist belt 1 are connected via a connecting mechanism 6, and the adapter bracket 63 on the connecting mechanism 6 is rotatable. This allows the booster device to rotate, allowing the user to adjust the direction of the booster device to meet the needs of different scenarios such as underwater operations or walking on shore, thereby improving user comfort. In addition, quick-release connections are used between the booster device and the waist belt 1, as well as between the power module and the power supply module 4. This allows the user to quickly and easily install and remove the booster device without the need for auxiliary tools. This not only improves ease of use, but also helps save time and improve efficiency. At the same time, the power module and the power supply module 4 use a non-wired connection, effectively avoiding safety hazards caused by wiring problems in underwater environments, and also improving the waterproof performance and operational stability of the entire device.

[0054] Please refer to Figures 3 to 6. In this embodiment, the connecting mechanism 6 also includes a pressing member 64, which is elastically and slidably installed in the hollow cavity. The pressing member 64 is provided with a pressure rod 641 and a limiting column 642. The pressure rod 641 extends to the outside of the hollow cavity, and the limiting column 642 is located in the hollow cavity. The adapter bracket 63 is provided with at least two limiting grooves 6321. The limiting column 642 can be inserted into different limiting grooves 6321 and can be disengaged from the limiting groove 6321 by sliding. Specifically, the pressing member 64 is a frame-like structure, and the adapter bracket 63 is arranged in the frame. The pressure rod 641 and the limiting column 642 provided on the frame are spaced apart along the same straight line, and the frame can move back and forth along the direction of the straight line. In this way, when the frame moves, the limiting column 642 can be disengaged from or inserted into the limiting groove 6321.

[0055] The connecting plate 61 and the adapter bracket 63 of this embodiment can be connected to the waist belt 1 and the booster device respectively. The adapter bracket 63 can rotate freely relative to the hollow cavity, so its angle and position can be easily adjusted according to actual needs, thereby providing greater operational flexibility. In addition, the cooperation between the limiting column 642 on the pressing member 64 and the limiting groove 6321 on the adapter bracket 63 can achieve stable locking of the mechanism at different angles. This locking mechanism is both simple and reliable, effectively preventing accidental rotation or loosening. By sliding the pressing member 64, the limiting column 642 can be easily disengaged from the limiting groove 6321, thereby unlocking the adapter bracket 63 and allowing it to rotate again. This unlocking method is intuitive and easy to operate, greatly improving the user experience.

[0056] Referring to Figures 3 and 4, in this embodiment, a holder 65 is provided within the hollow cavity, and a positioning hole 651 is provided on the holder 65. The limiting post 642 can be inserted into the limiting groove 6321 after passing through the positioning hole 651. The adapter bracket 63 includes a connecting seat 632 and an adapter plate 631. The adapter plate 631 is located outside the hollow cavity, the connecting seat 632 is provided within the holder 65, and the limiting groove 6321 is located on the connecting seat 632. At least two limiting grooves 6321 are spaced apart along the rotation direction of the adapter bracket 63. Specifically, the holder 65 has a cylindrical structure, and the adapter bracket 63 can be inserted into the holder 65, that is, it can rotate within the holder 65 to reduce the movable space of the adapter bracket 63 and make it more stable. The positioning hole 651 is located on one side of the holder 65 and is aligned with the pressure rod 641 and the limiting post 642. The connecting base 632 matches the clamping base 65 and is also cylindrical. The outer wall of the connecting base 632 can fit the inner wall of the clamping base 65, allowing the connecting base 632 to rotate along the inner wall of the clamping base 65. In this embodiment, two limiting grooves 6321 are used as an example. The two limiting grooves 6321 are arranged at a 90-degree interval, corresponding to the vertical and horizontal states of the adapter plate 631 respectively.

[0057] The holder 65 of this embodiment serves as the installation base of the adapter bracket 63, providing additional support and stability for the installation of the adapter bracket 63, and effectively reducing the shaking or deformation of the adapter bracket 63 when rotating or subjected to force; in addition, the holder 65 is provided with a positioning hole 651. When the adapter bracket 63 is installed on the holder 65, the limiting column 642 can pass through the limiting groove 6321 of the positioning hole 651 in turn, so that the limiting column 642 can always remain in the correct position without deviation, so that it can be accurately inserted into the limiting groove 6321, thereby improving the accuracy of positioning.

[0058] The adapter bracket 63 is divided into two parts: a connecting base 632 and an adapter plate 631. The connecting base 632 is rotatably connected to the card base 65, so that the connecting base 632 can rotate in the card base 65, and the adapter plate 631 can be connected to the booster device, which can greatly facilitate the assembly and use of the adapter bracket 63; and at least two limit grooves 6321 are arranged at intervals along the rotation direction of the adapter bracket 63, so that when the adapter bracket 63 is rotated, it can be selected to lock at different angles, thereby meeting the flexibility in different scenarios and usage requirements.

[0059] Please refer to Figures 4 and 5. In this embodiment, an arc-shaped positioning groove 652 is provided in the base 65, and a positioning block 6322 is provided on the connecting base 632. The positioning block 6322 can abut against both ends of the arc-shaped positioning groove 652. The arc-shaped positioning groove 652 can be set at the center position in the base 65, that is, around the rotation center of the adapter bracket 63. The arc-shaped positioning groove 652 and the positioning block 6322 cooperate with each other, and the rotation range of the adapter bracket 63 can be limited by flexibly setting the structural dimensions of the two. For example, the rotation range of the adapter bracket 63 can be limited to 0-90 degrees. When the positioning block 6322 abuts against the two ends of the arc-shaped positioning groove 652, they correspond to the positions of 0 degrees and 90 degrees respectively.

[0060] The combined use of the arcuate positioning groove 652 and the positioning block 6322 of this embodiment allows for more precise rotation of the adapter bracket 63. When the adapter bracket 63 is rotated to the desired angle, the positioning block 6322 abuts against the end of the arcuate positioning groove 652, thereby ensuring the stability and accuracy of the adapter bracket 63. Furthermore, the ends of the arcuate positioning groove 652 serve as the rotation limits of the adapter bracket 63, effectively preventing excessive rotation of the adapter bracket 63. They also serve as signals indicating that the adapter bracket 63 has reached its full rotation position, ensuring accurate alignment between the limit post 642 and the limit groove 6321.

[0061] Referring to Figure 3, in this embodiment, the adapter bracket 63 is connected to the connecting plate 61 via a tapping screw 66. The tapping screw 66 can be used to connect the adapter bracket 63 to the connecting frame, maintaining a fixed spacing between the adapter bracket 63 and the connecting frame, and ensuring that the adapter bracket 63 can rotate, which is simple and effective. During installation, the tapping screw 66 can be passed through the rotation center of the adapter bracket 63. One end of the tapping screw 66 is clamped to the outside of the connecting plate 61, and the other end is threadedly connected to the adapter bracket 63. At this time, the tapping screw 66 is fixedly connected to the adapter bracket 63, that is, it can rotate relative to the connecting plate 61. In this way, the adapter bracket 63 can be connected without affecting the rotation of the adapter bracket 63.

[0062] Referring to Figures 2 and 3 , in this embodiment, a locking bracket 67 is provided on the adapter bracket 63, and the locking bracket 67 is elastically connected to the adapter bracket 63 via a locking torsion spring 68. The locking bracket 67 is provided to facilitate the connection between the adapter bracket 63 and the mounting base 41. Specifically, the locking bracket 67 can be used to lock the mounting base 41 to the adapter bracket 63, thereby facilitating the synchronous rotation of the adapter bracket 63 and the mounting base 41. This also makes locking the mounting base 41 easier, making the operation process simple and quick, and further improving the user experience.

[0063] It should be noted that the adapter plate 631 is provided with a vertical locking slot, and the locking frame 67 is arranged at the edge of the locking slot. The mounting base 41 can be inserted into the locking slot, and the mounting base 41 is also provided with a plurality of locking notches that cooperate with the locking frame 67. The locking frame 67 can adjust the position of the booster device by cooperating with different locking notches.

[0064] Referring to Figure 4 , in this embodiment, the pressing member 64 is elastically connected to the hollow cavity via an elastic member 69. A top plate 610 is provided in the hollow cavity, and the elastic member 69 is located between the top plate 610 and the pressing member 64. Because the elastic member 69 is located between the top plate 610 and the pressing member 64, when the pressing member 64 is operated, that is, when the pressing rod 641 is pressed, the elastic member 69 can provide stable elastic feedback, and when the pressing rod 641 is released, the pressing member 64 can automatically reset. This allows for quick unlocking and locking of the adapter bracket 63.

[0065] Continuing with Figure 4, in this embodiment, a slot 611 is provided within the hollow cavity, and a pressing member 64 is movably engaged within the slot 611. The slot 611 serves to limit the pressing member 64, limiting its movement to one direction. This ensures the stability and accuracy of the movement of the pressing member 64, and ensures that the adapter bracket 63 can be effectively unlocked and locked, thereby allowing the device to operate smoothly.

[0066] Please refer to Figures 7, 8 and 9. In this embodiment, the snap button assembly 5 includes an inner key 51, an outer key 52 and a self-locking key 53. The inner key 51 rotates and is spaced apart with a first pin 54 and a second pin 55. The outer key 52 is rotatably connected to the first pin 54. One end of the outer key 52 is close to the first pin 54 and the other end is provided with a hook 521; the self-locking key 53 is elastically clamped on the inner key 51 and is located between the first pin 54 and the second pin 55. A lock hole 534 is also provided on the self-locking key 53; the inner key 51 is rotatably installed on the power module through the second pin 55, and a card block 40 is provided on the power module 4 to match the hook 521. The power module is provided with a hook 30 that matches the lock hole 534. The inner key 51 can be locked by the hook 30, and the hook 30 can be locked by the card block 40.

[0067] The arrangement of the inner key 51, outer key 52 and self-locking key 53 in the snap assembly 5 of this embodiment enables the power module and the power supply module 4 to form a stable structure when connected; the self-locking key 53 also enables the device to automatically lock after connection, preventing module separation due to unexpected circumstances during use, and effectively improving the stability of the connection between modules.

[0068] To unlock the snap assembly 5, the self-locking key 53 is pressed to disengage the self-locking key 53 from the lock hole 534. At this time, the inner key 51 is in a rotatable state. Then, the end of the inner key 51 close to the first pin 54 is moved, causing the entire snap assembly 5 to rotate around the second pin 55. This allows the hook 521 on the outer key 52 to be disengaged and free. At this time, the outer key 52 is moved again to rotate around the first pin 54 to complete the unlocking. Similarly, when locking is required, the outer key 52 is first fastened to the clamping block 40, and then the inner key 51 is fastened to the hook 30.

[0069] Referring to Figure 8 , in this embodiment, a slotted hole 511 is provided on the inner key 51. The self-locking key 53 includes a pressing plate 531, a locking plate 532, and a stopper 533. The pressing plate 531 is located on one side of the inner key 51. The locking plate 532 slides and engages within the slotted hole 511. The stopper 533 is located on the locking plate 532 and can abut against the sidewall of the slotted hole 511. The locking hole 534 is located on the locking plate 532. Specifically, the slotted hole 511 is square and located between a first pin 54 and a second pin 55. The first and second pins 54 and 55 are arranged parallel to each other. The self-locking key 53 can slide within the slotted hole 511 along the axial direction of the first pin 54 or the second pin 55. The stopper 533 is removable to facilitate assembly of the locking plate 532. In this embodiment, the stopper 533 is a screw that is directly threadedly connected to the locking plate 532 to form the stopper 533.

[0070] This embodiment provides a slot 511 on the inner key 51, allowing the self-locking key 53 to be securely inserted and slide within the slot 511, thereby enhancing the stability of the connection between the self-locking key 53 and the inner key 51. By pressing the pressing plate 531, the locking plate 532 can be moved within the slot 511, making operation simple and convenient. Furthermore, a limiter 533 is provided on the locking plate 532. When the locking plate 532 is locked, the limiter 533 effectively prevents the locking plate 532 from sliding within the slot 511, thereby ensuring the locking function of the snap assembly 5 and effectively preventing the locking plate 532 from disengaging from the slot 511.

[0071] Continuing with Figure 8 , in this embodiment, the lock plate 532 is further provided with a positioning post 5321. A positioning hole 651 matching the positioning post 5321 is provided within the slot 511. An elastic member 56 is sleeved over the positioning post 5321 and positioned between the lock plate 532 and the inner sidewall of the slot 511. Specifically, the pressing plate 531 and the positioning post 5321 are located on opposite sides of the lock plate 532, and the positioning post 5321 is located on one side of the sliding direction of the lock plate 532. That is, the positioning post 5321 and the lock plate 532 always slide in the same direction.

[0072] The positioning post 5321 and positioning hole 651 of this embodiment serve to guide and limit the sliding of the lock plate 532, allowing the lock plate 532 to slide back and forth in only one direction. That is, when the pressing plate 531 is pressed, the lock plate 532 slides, simultaneously driving the positioning post 5321 to slide within the positioning hole 651. This ensures the accuracy and stability of the lock plate 532 during the sliding process, thereby improving the unlocking or locking operation experience. The provision of the elastic member 56 can serve as a reset function. When the lock plate 532 moves under the action of an external force and allows the lock hole 534 to disengage from the locking member such as the hook 30, the elastic member 56 can reset the lock plate 532 to its original position, facilitating operations such as relocking the snap assembly 5.

[0073] Please continue to refer to Figure 8. In this embodiment, the outer key 52 is rotatably connected to the first pin 54 through a connecting block 57. The connecting block 57 is close to one end of the outer key 52, and the end of the outer key 52 close to the first pin 54 can abut on the inner key 51.

[0074] The connection block 57 of this embodiment is provided to facilitate the connection between the outer key 52 and the first pin 54. On the other hand, it also allows a certain amount of space between the outer key 52 and the inner key 51, thereby facilitating the rotation of the outer key 52. ​​In addition, when the outer key 52 is rotated to a certain angle, one end of the outer key 52 can abut against the inner key 51. In other words, the inner key 51 also acts as a limiter for the outer key 52, preventing the outer key 52 from rotating too far and affecting the user experience.

[0075] Continuing with Figure 8 , in this embodiment, the inner key 51 is provided with a plurality of stoppers 512 at one end proximal to the second pin 55. The stoppers 512 have inclined surfaces on the side facing away from the outer key 52. ​​The stoppers 512 are provided to prevent excessive rotation of the snap mechanism. When the inner key 51 is rotated to a certain angle, the inclined surfaces of the stoppers 512 abut against the electrical control cabin assembly 3, preventing further rotation of the inner key 51. This prevents excessive rotation of the inner key 51 and compromises the user experience.

[0076] Continuing with reference to FIG8 , in this embodiment, a first torsion spring 58 is provided on the first pin 54, and a second torsion spring 59 is provided on the second pin 55. One end of the first torsion spring 58 and one end of the second torsion spring 59 can both abut against the outer key 52. ​​Specifically, the function of the first torsion spring 58 is to automatically push open the inner key 51 when the snap assembly 5 is in the unlocked state, allowing the inner key 51 to automatically rotate to the maximum limit position; the function of the second torsion spring 59 is to automatically push open the outer key 52 when the snap assembly 5 is in the unlocked state, allowing the outer key 52 to automatically rotate to the maximum limit position. In this way, the user does not need to manually move the outer key 52 or the inner key 51, thereby further improving the user experience.

[0077] 7 or 11 , in this embodiment, the power module includes a drive assembly 2 and an electric control cabin assembly 3 , wherein the drive assembly 2 is wirelessly connected to the power module 4 via the electric control cabin assembly 3 . The hook 30 is located outside the electric control cabin assembly 3 .

[0078] The setting of the electric control cabin component 3 eliminates the need for cables to connect the drive component 2 and the power module 4, making assembly simpler and faster, reducing the size and weight of the equipment, reducing electrical failures and safety hazards, and eliminating problems such as entanglement, wear and corrosion caused by cable connections, allowing the device to better adapt to various complex underwater environments.

[0079] Referring to Figures 12, 13, and 14, in this embodiment, the drive assembly 2 includes a duct 21, a drive member 22 disposed within the duct 21, and a propeller 23 connected to the output end of the drive member 22. The electrically adjustable cabin assembly 3 includes a cabin body 31, an electrically adjustable board 32, and an adapter 33. The electrically adjustable board 32 is disposed within the cabin body 31. The drive member 22 has a plurality of connection ends 221. The cabin body 31 has a plurality of through-holes 311, each of which is embedded with a sealing ring 34. The connection ends 221 pass through the through-holes 311 to connect to the electrically adjustable board 32. The adapter 33 has a plurality of pins 331 at each end. One end of the adapter 33 is connected to the electrically adjustable board 32, and the other end is connected to the power module 4. The number and arrangement of the through-holes 311 correspond to the number of the connection ends 221, and each connection end 221 can pass through a corresponding through-hole 311. Of course, as another implementation, the number of the through holes 311 may be greater than the number of the connecting ends 221 , but cannot be less than the number of the connecting ends 221 .

[0080] This embodiment, through the provision of the connection end 221, adapter 33, and electrical adjustment plate 32, allows the driver 22 to connect to the battery without the use of cables or wires, thus avoiding problems such as cable damage and poor contact. Furthermore, a sealing ring 34 is provided in the through hole 311 of the cabin 31, creating a static connection between the sealing ring 34 and the driver 22, reducing the risk of water seepage and improving the sealing effect of the underwater propulsion device.

[0081] Referring to Figure 12, in this embodiment, the driver 22 is provided with a mounting hole 222, and the cabin 31 is provided with a mounting post 312 corresponding to the mounting hole 222. The depth of the mounting hole 222 matches the height of the mounting post 312. The mounting post 312 is connected to the mounting hole 222, ensuring a stable connection between the driver 22 and the cabin 31, and further ensuring a stable connection between the connection end 221 and the electric adjustment board 32, thereby preventing poor contact between the driver 22 and the electric adjustment board 32. In this embodiment, two mounting holes 222 and two mounting posts 312 are provided. During installation, the two mounting posts 312 are aligned with the two mounting holes 222, respectively, so that the driver assembly 2 and the electric adjustment cabin assembly 3 are plugged together. Furthermore, the depth of the mounting hole 222 matches the height of the mounting post 312, allowing the mounting post 312 to seamlessly extend into the mounting hole 222, ensuring a seamless connection between the driver 22 and the cabin 31, and further reducing the risk of water leakage in the underwater booster.

[0082] Continuing with Figure 12, in this embodiment, the driver 22 is connected to a mounting plate 24. Mounting plate 24 is sleeved around the periphery of the driver 22, blocking the gap between the driver 22 and the duct 21. This prevents water from entering the cabin 31 through the gap, further improving the sealing of the booster. The diameter of the driver 22 is smaller than that of the duct 21, allowing the driver 22 to be positioned unobstructed within the duct 21. Furthermore, a gap exists between the entrance of the duct 21 and the driver 22. Mounting plate 24 is provided around the periphery of the driver 22 to block this gap. It should be noted that the driver 22 in this embodiment is a motor.

[0083] At the same time, the duct 21 is provided with a positioning boss 211, and the cabin body 31 is provided with a positioning groove 313 corresponding to the positioning boss 211. The positioning boss 211 and the positioning groove 313 enable the installation staff to quickly and accurately install the drive assembly 2 and the electric control cabin assembly 3 during installation, thereby improving assembly efficiency.

[0084] 7 and 11 , in this embodiment, a water inlet shield 25 is provided at the end of the duct 21 , a water inlet grille 212 is provided on the side of the duct 21 , and the water inlet shield 25 is detachably connected to the duct 21 .

[0085] The water inlet shield 25 protects the duct 21, preventing underwater debris from entering and affecting the underwater booster's performance. Furthermore, the detachable connection between the water inlet shield 25 and the duct 21 allows the power module to be replaced with only the damaged components, such as the duct 21, propeller 23, drive element 22, and water inlet shield 25, if damaged, without having to discard the entire booster, significantly reducing operational costs. Furthermore, the water inlet grille 212 on the side of the duct 21 effectively increases the amount of water entering the underwater booster, facilitating the operation of the propeller 23 and enhancing the booster's effectiveness.

[0086] Referring to Figure 15 , in this embodiment, propeller 23 comprises a propeller cap 231 and three spiral blades 232 evenly distributed around the outer periphery of propeller cap 231. Blades 232 are arranged in a spiral pattern around the outer periphery of propeller cap 231. The arrangement of three spiral blades 232 around the outer periphery of propeller cap 231 helps improve the thrust and efficiency of propeller 23.
