Detailed Implementation

[0010] The embodiments of this application are described in detail below. These embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0011] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0012] In the application scenarios of water propulsion devices, batteries need to adapt to frequent replacements and require convenient user operation. The battery removal method directly affects the user experience. Traditional battery removal methods have obvious limitations. For example, traditional latching mechanisms require disengaging the physical latch before disconnecting the power interface, resulting in a long battery replacement time. The latch design relies on manual alignment, and the latch is easily affected by the water environment. In a turbulent environment, positioning deviations can easily lead to battery removal failures. Vibrations of the water propulsion device may also cause the latch to accidentally disengage, causing the battery to fall out and threatening user safety. To solve the above technical problems, this application provides a water propulsion device 100 ( Figure 1 ) and 1000 mobile watercraft ( Figure 17 ).

[0013] Please see Figure 1 and Figure 17 The water-based mobile device 1000 includes a water-based propulsion unit 100 and a water-based carrier 300. The water-based propulsion unit 100 is a detachable power unit. When in use, the water-based propulsion unit 100 is connected to the water-based carrier 300, providing power and propelling the water-based carrier 300 in the water. When not in use, the water-based propulsion unit 100 can be detached from the water-based carrier 300 for maintenance and repair. For example, the water-based mobile device 1000 in this embodiment can be a passenger ship, yacht, or other type of vessel; correspondingly, the water-based carrier 300 can be a hull, and the water-based propulsion unit 100 can be an outboard motor. For example, the water-based mobile device 1000 can also be a fishing boat, sailboat, or other vessel, without limitation. For example, the water-based propulsion unit 100 can also be a stern motor or a trolley motor, without limitation. The water-based carrier 300 can also be a buoy or a rubber float, without limitation.

[0014] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8The water propulsion device 100 is configured to propel the water carrier 300 in water. The water propulsion device 100 includes a main body 10, a battery 30, and a connecting assembly 50. The main body 10 includes a fuselage 11 and a battery holder 13 disposed on top of the fuselage 11. The fuselage 11 is connected to the water carrier 300. The battery holder 13 has a first electrical contact 131. The battery 30 is pluggable into the battery holder 13, and the battery 30 has a second electrical contact 31 and a connector 33. The connecting assembly 50 is rotatably connected to the battery holder 13. The connecting assembly 50 is configured to rotate about a rotation axis 51 to switch between a locked state and an unlocked state, and allows the connector 33 to switch between a locked position 501 and an unlocked position 503 of the connecting assembly 50. In the locked state, the connector 33 is located in the locked position 501, the first electrical connector 131 and the second electrical connector 31 are engaged and electrically connected along the insertion direction S, and the battery 30 is prohibited from disengaging from the battery holder 13 along the insertion direction S; in the unlocked state, the connector 33 is located in the unlocked position 503, the first electrical connector 131 and the second electrical connector 31 are separated along the insertion direction S, and the insertion direction S intersects with the rotation shaft 51.

[0015] Specifically, the main body 11 provides a mounting location for other structures of the water thruster 100. A battery holder 13 is mounted on top of the main body 11. The battery holder 13 carries and connects to the battery 30. A first electrical connector 131 and a second electrical connector 31 electrically connect the battery holder 13 and the battery 30. With the first electrical connector 131 and the second electrical connector 31 electrically connected, the battery 30 can output electrical energy to the main body 10, thereby establishing an electrical energy transmission channel between the battery 30 and the main body 10, ensuring that the water thruster 100 can receive a power supply for normal operation. A connector 33 and a connecting assembly 50 detachably connect the battery 30 and the battery holder 13, ensuring that the battery 30 can be removed from the battery holder 13 and that the battery 30 can be installed and secured to the battery holder 13.

[0016] The connecting component 50 is rotatably connected to the battery holder 13. The connecting component 50 can rotate around the rotation axis 51 to switch between locked and unlocked states. In the locked state ( Figure 1 , Figure 3 and Figure 7 When the connector 33 is in the locked position 501, the first electrical connector 131 and the second electrical connector 31 are tightly fitted together along the insertion direction S and electrically connected, so that the battery 30 can stably provide power to the water propulsion device 100, ensuring that the water propulsion device 100 propels the water carrier 300 to move normally in the water. In the unlocked state ( Figure 2 , Figure 6 and Figure 9When the connector 33 is in the unlocked position 503, the first electrical connector 131 and the second electrical connector 31 are separated along the insertion direction S. The insertion direction S refers to the direction in which the battery 30 is inserted or removed relative to the battery holder 13 when the battery 30 is plugged into and engaged with the battery holder 13. Specifically, when the battery 30 is installed on the battery holder 13, the battery 30 moves along the insertion direction S, and the second electrical connector 31 aligns and engages with the first electrical connector 131 on the battery holder 13, thereby achieving electrical connection. Conversely, when it is necessary to remove the battery 30, the battery 30 moves in the opposite direction along the insertion direction S, causing the second electrical connector 31 to separate from the first electrical connector 131. The locked position and unlocked position are the relative positions of the connector 33 and the connecting assembly 50.

[0017] In the water propulsion device 100 of this application, the connecting component 50 can rotate around the rotation axis 51, and the insertion direction S intersects the rotation axis 51. The circular motion generated by the rotation can be converted into linear motion of the connecting member 33 along the insertion direction S. The connecting component 50 can drive the connecting member 33 to switch between the locked position 501 and the unlocked position 503, thereby realizing the electrical connection or separation of the first electrical connector 131 and the second electrical connector 31 along the insertion direction S. This allows for quick installation and removal of the battery 30, improving the convenience and reliability of battery installation and removal, facilitating users to quickly replace the battery 30 according to different needs, and improving the flexibility of the water propulsion device 100. For example, the insertion direction S is perpendicular to the rotation axis 51.

[0018] Please see Figures 7 to 9 In any of the figures, in some embodiments, the rotation area of ​​the connecting component 50 is located on the side of the rotation shaft 51 away from the insertion position of the first electrical connector 131 and the second electrical connector 31, and the locked position 501 is closer to the rotation shaft 51 than the unlocked position 503.

[0019] Specifically, the locking position 501 is closer to the rotation axis 51 than the unlocking position 503. That is, with the rotation axis 51 as the center, the locking position 501 and the unlocking position 503 are eccentric. When the connecting component 50 switches from the locked state to the unlocked state, the connecting component 50 will generate an upward force during rotation. The force acts on the battery 30 and can push the battery 30 out in the height direction Z. After being pushed out, the first electrical connector 131 and the second electrical connector 31 are separated, which makes it convenient for the user to take out the battery 30 after unlocking. This reduces the collision between the first electrical connector 131 and the second electrical connector 31, reduces the difficulty for the user to manually pull out the battery 30, and improves the convenience and efficiency of battery 30 disassembly.

[0020] Please see Figures 7 to 11In any of the figures, in some embodiments, the connecting assembly 50 is provided with a cam arc surface 53 arranged about a rotation axis 51. A locking position 501 and an unlocking position 503 are located at both ends of the cam arc surface 53, which is configured to slide in engagement with the connecting member 33.

[0021] Specifically, the cam arc surface 53 is used to support the connector 33. When the connecting assembly 50 rotates around the rotation axis 51, the connector 33 slides along the cam arc surface 53, thereby switching from the locked position 501 to the unlocked position 503, or from the unlocked position 503 to the locked position 501. There can be one or more cam arc surfaces 53. This application includes two cam arc surfaces 53, respectively disposed on opposite sides along the extension direction X of the rotation axis 51. The cam arc surface 53 is a continuous curve or arc shape, which can guide the connector 33 to move smoothly. The sliding fit also helps to reduce friction between the connector 33 and the cam arc surface 53, reducing jamming during the movement of the connector 33.

[0022] Please see Figures 7 to 11 In any of the figures, in some embodiments, the connecting assembly 50 is provided with a mating groove 54 that accommodates a portion of the connecting member 33. The cam arc surface 53 is arranged as the side of the mating groove 54 near the rotating shaft 51.

[0023] Specifically, the mating groove 54 is recessed in the extension direction X of the rotating shaft 51, and the mating groove 54 includes two opposing side surfaces. The cam arc surface 53 is one of the side surfaces of the mating groove 54. There are two mating grooves 54, and the connector 33 is inserted into the two mating grooves 54 at opposite ends in the X direction. The mating groove 54 provides a receiving space for the end of the connector 33, so that the connector 33 can be kept within a predetermined trajectory during the rotation of the connecting assembly 50. The two side surfaces of the mating groove 54 can limit the displacement of the connector 33 along the insertion direction, preventing the connector 33 from shaking or disengaging from the mating groove 54. When the connecting assembly 50 switches between a locked state and an unlocked state, the connector 33 slides along the cam arc surface 53 within the mating groove 54. When the connector 33 is displaced relative to the connecting assembly to the locked position 501, the connector 33 slides to one end of the cam arc surface 53, connecting the battery 30 to the battery holder 13. At this time, the connector 33 is stably housed in the mating groove 54, and the mating groove 54 prevents the connector 33 from moving along the insertion direction. When the connector 33 is displaced relative to the connecting assembly to the unlocked position 503, the connector 33 slides to the other end of the cam arc surface 53, separating the battery 30 from the battery holder 13, facilitating the removal of the battery 30.

[0024] Please see Figures 7 to 9 In any of the figures, in some embodiments, the mating groove 54 is provided with a loading / unloading opening 541. The loading / unloading opening 541 allows the connector 33 to disengage from the mating groove 54 from the unlocked position 503 and allows the battery 30 to be removed from the battery holder 13.

[0025] Specifically, the loading / unloading opening 541 is located on the side of the mating groove 54 away from the rotation axis 51. The connector 33 can enter or exit the mating groove 54 through the loading / unloading opening 541. There can be one or more loading / unloading openings 541. At least in the unlocked state, the loading / unloading opening 541 allows the connector 33 to disengage from the mating groove 54. The user can move the battery 30 along the insertion direction S, causing the connector 33 to disengage from the mating groove 54 through the loading / unloading opening 541, thereby achieving quick disassembly of the battery 30.

[0026] Please see Figure 2 or Figure 3 ,as well as Figure 15 In some embodiments, the battery holder 13 is provided with a pre-guide 133. The pre-guide 133 is configured to pre-guide the battery 30 during assembly of the battery holder 13. When the connection assembly 50 is in the unlocked state, the pre-guide 133 pre-guides the battery 30 to guide the connection 33 to align with the loading / unloading opening 541.

[0027] Specifically, when the connecting assembly 50 is in the unlocked state, the pre-guide 133 guides the connecting member 33 to align with the loading / unloading opening 541. Exemplarily, the pre-guide 133 includes a pre-guide block 1331, the protrusion of which is oriented in the extension direction X of the rotation shaft 51. During the process of the connecting assembly 50 switching from the unlocked state to the locked state, i.e. Figure 15 (a) to Figure 15 (b) The battery 30 contacts the preguide block 1331, which guides the battery 30 downward along the insertion direction S. Exemplarily, the preguide member 133 includes a preguide groove 1333, which is disposed on the battery holder and located at the end of the connecting assembly 50 away from the battery. The preguide groove 1333 prevents the battery 30 from tilting towards the preguide groove 1333, and also visually aids in identifying the installation position and orientation of the battery 30.

[0028] Please see Figures 7 to 9 In any of the figures, in some embodiments, the battery holder 13 is provided with an unlock limit 134. The unlock limit 134 restricts the connection component 50 to be in the unlocked state at the first extreme position 505. When the connection component 50 is in the first extreme position 505, the loading and unloading opening 541 is located on the connector 33 along the parallel insertion direction S between the first electrical connector 131 and the second electrical connector 31.

[0029] Specifically, the first extreme position 505 is the extreme position that the connecting component 50 can reach in the unlocked state. When the connecting component 50 is in the unlocked state and is driven to the first extreme position 505, the loading / unloading opening 541 is located in the insertion direction S. The unlocking limit 134 is used to limit the excessive rotation of the connecting component 50 in the unlocked state. That is, the unlocking limit 134 can limit the orientation of the first extreme position 505. The unlocking limit 134 can be a protrusion, a stop, a stop pin, etc., which are not limited here. For example, the unlocking limit 134 includes a protrusion provided on the battery holder 13. When the connecting component 50 is in the unlocked state and is driven to the first extreme position 505, the unlocking limit 134 can abut against at least a part of the outer side wall of the connecting component 50, limiting the connecting component 50 from continuing to rotate. The loading / unloading opening 541 is located in the insertion direction S, and the connector 33 can enter and exit the loading / unloading opening 541 along the insertion direction S. In this way, the battery 30 can be quickly loaded and unloaded along the insertion direction S.

[0030] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the battery holder 13 is provided with an elastic element 135 for connecting the connection assembly 50. The elastic force of the elastic element 135 drives the connection assembly 50 to resist the unlocking limit 134.

[0031] Specifically, exemplarily, the elastic element 135 of this application is a tension spring. In the unlocked state, the elastic element 135 is in a stretched state. The elastic force of the elastic element 135 pulls the connecting component 50 against the unlock limit 134, thereby keeping the connecting component 50 in the first limit position 505, which can prevent the connecting component 50 from being displaced unnecessarily due to external interference in the unlocked state.

[0032] Please see Figures 5 to 9 In some embodiments, the locking position 501 is located at the end of the mating groove 54. The connector 33 is in the locking position 501, and the elastic member 135 drives the connecting assembly 50 to rotate relative to the connector 33 to the second limit position 507.

[0033] Specifically, in the locked state ( Figure 5 and Figure 7 The elastic element 135 is also in a stretched state. When the connecting component switches from the locked state to the unlocked state, the elastic element... Figure 5 The state changed to Figure 6 In this state, it can be understood that one end of the elastic element 135 is connected to the battery holder 13, and the other end is connected to the connecting assembly 50. The position where it is connected to the connecting assembly 50 is eccentric relative to the extension direction X of the rotation axis 51. Therefore, the elastic element is formed by... Figure 5 The state changed to Figure 6 In this state, the elastic element 135 first stretches and then shortens; here, the shortening is relative to the elastic element. Figure 5 The state changed to Figure 6 The maximum length under the condition of elastic member 135 is not limited to when elastic member 135 is in a compressed state. During the process of elastic member 135 first being stretched and then shortened, it can always be in a stretched state. In this way, elastic member 135 can drive connecting assembly 50 to rotate relative to connecting member 33 to the second limit position 507 through elastic force.

[0034] Please see Figure 7 In some embodiments, the battery holder 13 is provided with a locking limit 138. The locking limit 138 restricts the connection assembly 50 to a locked state at a second extreme position 507.

[0035] The locking limit 138 is used to limit excessive rotation of the connecting assembly 50 in the locked state. That is, the locking limit 138 can limit the orientation of the second extreme position 507. The locking limit 138 can be a protrusion or a retaining spring, etc., and is not limited here. For example, the locking limit 138 includes a protrusion provided on the battery holder 13. When the connecting assembly 50 is in the locked state and driven to the second extreme position 507, the locking limit 138 can abut against at least a portion of the outer side wall of the connecting assembly 50, limiting the connecting assembly 50 from continuing to rotate. For example, the locking limit 138 can also be a portion of the side wall of the mating groove 54. When the connecting assembly 50 is in the locked state at the second extreme position 507, the connector 33 abuts against the locking limit 138, limiting the connector 33 from continuing to rotate.

[0036] Please see Figures 7 to 9 In some embodiments, the mating groove 54 is provided with a limiting arc surface 543 opposite to the cam arc surface 53. The limiting arc surface 543 prevents the connector 33 from disengaging from the mating groove 54 outside the unlocked position 503.

[0037] Specifically, the limiting arc surface 543 refers to the two opposite sides of the mating groove 54 in the height direction Z. One is the cam arc surface 53 close to the rotating shaft 51, and the other is the limiting arc surface 543 away from the rotating shaft 51. The cam arc surface 53 and the limiting arc surface 543 can limit the displacement of the connecting member 33 in the height direction Z, preventing the connecting member 33 from shaking or disengaging from the mating groove 54.

[0038] Please see Figures 7 to 9 In some embodiments, the cam arc surface 53 has an unlocking groove 531 at the unlocking position 503. The connector 33 engages with the unlocking groove 531 to be positioned at the unlocking position 503.

[0039] Specifically, when the connecting component 50 is rotated to the unlock position 503, the connector 33 can be embedded in the unlock groove 531. On the one hand, it can position the unlock position 503 so that the user can perceive that the connector 33 is in the unlock position 503. On the other hand, it can improve the stability of the connector 33 in the unlock position 503 and prevent the connector 33 from being displaced in the unlock position 503.

[0040] Please see Figures 7 to 9 In some embodiments, the cam arc surface 53 is provided with a locking groove 533 in the locking position 501. The connector 33 engages with the locking groove 533 to be positioned in the locking position 501.

[0041] Specifically, when the connecting component 50 is rotated to the locking position 501, the connector 33 can be embedded in the locking groove 533. On the one hand, the locking position 501 can be positioned so that the user can perceive that the connector 33 is in the locking position 501. On the other hand, the stability of the connector 33 in the locking position 501 can be improved to prevent the connector 33 from being displaced in the locking position 501.

[0042] Please see Figure 11 In some embodiments, the mating groove 54 is provided with an auxiliary opening 545. The connector 33 slides into the mating groove 54 through the auxiliary opening 545, and the gravity of the battery 30 drives the connector 33 to move toward the locking position 501.

[0043] Specifically, the auxiliary opening 545 allows the connector 33 to slide into the mating groove 54, and the connector 33 can also exit the mating groove 54 from the auxiliary opening 545. During the installation of the battery 30 into the battery holder 13, the connector 33, driven by the weight of the battery, slides from the auxiliary opening 545 into the mating groove 54, reducing the difficulty of alignment between the connector 33 and the mating groove 54. Under the weight of the battery 30, the connector slides along the cam arc surface 53 towards the locking position 501, eliminating the need for excessive force from the user to push the connector 33. This improves the convenience and efficiency of battery installation and reduces the risk of component damage due to improper manual operation. During the removal of the battery 30 from the battery holder 13, the user can lift the battery 30 along the insertion direction S, causing the connector 33 to disengage from the mating groove 54 from the auxiliary opening 545, thus achieving quick removal of the battery 30.

[0044] Please see Figures 1 to 4 In some embodiments, the connecting assembly 50 is provided with a cover plate 55. The connecting assembly 50 has a closed state, and when the connecting assembly 50 is rotated to the closed state, the cover plate 55 closes with the first electrical contact 131. The unlocked state, locked state, and closed state are configured to be sequentially presented by the connecting assembly 50 rotating along a first rotation direction R1.

[0045] Specifically, the first electrical connector 131 includes an insulating base portion 1311 and a conductive terminal portion 1313. The insulating base portion 1311 has a cavity. The insulating base portion 1311 is supported by the battery holder 13, and the conductive terminal portion 1313 is housed within the cavity. The conductive terminal portion 1313 is used for electrical connection with the second electrical connector 31. When the connecting assembly 50 continues to rotate along the first rotation direction R1 from a locked state or an unlocked state to a closed state, the cover plate 55 gradually rotates from top to bottom and approaches the insulating base portion 1311. In the closed state ( Figure 4 The battery 30 is detached from the battery holder 13, and the cover plate 55 is fastened to the outer periphery of the insulating base 1311, so that the lower surface of the cover plate 55 is in contact with the top surface of the insulating base 1311, thereby covering the cavity and preventing external moisture and foreign objects from directly contacting the conductive terminal portion 1313. The cover plate 55 is used to physically protect the first electrical contact 131, preventing external foreign objects from entering or contacting the first electrical contact 131, thereby avoiding short circuits, corrosion or other damage. In addition, the cover plate 55 can also play a role in dustproofing and waterproofing. The unlocked state, locked state and closed state are configured to be presented by the connection assembly 50 rotating in a first rotation direction R1 in sequence. Specifically, when the connection assembly 50 rotates in the first rotation direction R1, it passes through the unlocked state, locked state and closed state in sequence. The user can complete the entire process from battery 30 removal preparation (unlocked state) to battery 30 fixing (locked state) and then to the protection of the first electrical contact 131 (closed state) by rotating the connection assembly 50 in a single rotation direction in sequence, which improves the continuity of user operation. In the embodiments of this application, when the connecting component 50 is in the unlocked state, the cover plate 55 abuts against the protrusion of the battery holder 13, thereby enabling the connecting component 50 to be located in the first extreme position 505, so that the loading and unloading opening 541 is located in the insertion direction S.

[0046] Please see Figures 1 to 4 In some embodiments, the connecting assembly 50 includes a control member 56 and a rotating member 57. The control member 56 is configured for user operation. The rotating member 57 is connected to the control member 56, and the control member 56 is configured to drive the rotating member 57 to rotate about a rotation axis 51, in a locked state ( Figure 1 , Figure 3 and Figure 7 The rotating part 57 is connected to the connecting part 33.

[0047] Specifically, the control element 56 is for the user to hold, and the user can operate the control element 56 to drive the rotating element 57 to rotate around the rotation axis 51, thereby realizing the switching of the connecting component 50 between different states. The control element 56 can be a lever, a knob, etc., as long as it allows the user to apply force to rotate it. The control element 56 and the rotating element 57 can be one or more. In this application, there is one control element 56 for easy one-handed operation, and there are two rotating elements 57. Each rotating element 57 is provided with a cam arc surface 53 and / or a mating groove 54. The cover plate 55 is connected between the two rotating elements 57, so that a single control element 56 can drive the two rotating elements 57 to rotate. In the locked state ( Figure 1 , Figure 3 and Figure 7 The rotating part 57 is connected to the connecting part 33. Both ends of the rotating part 57 are respectively supported by the cam arc surfaces 53 and / or mating grooves 54 of the two connecting parts 33. When the operating part 56 rotates, the operating part 56 drives the cam arc surfaces 53 in the mating grooves 54 to slide and engage with the connecting parts 33, causing the connecting parts 33 to switch between the locked position 501 and the unlocked position 503, i.e., gradually moving from... Figure 7 Switch to Figure 8 ,to Figure 9 .

[0048] Please see Figures 3 to 4 In some embodiments, the control member 56 is provided with a lever 561. The end of the lever 561 away from the rotating member 57 is configured to manually drive the rotating member 57 to rotate.

[0049] Specifically, lever 561 includes a rotating component 57 connected at one end and a part for the user to grip and apply force at the other end. When the user grips lever 561 and applies force, the force is transmitted to the rotating component 57 through lever 561, thereby causing the rotating component 57 to rotate around the rotation axis 51, realizing the switching of the connecting component 50 between different states. Lever 561 utilizes the lever principle to amplify the force applied by the user, making the rotation of the rotating component 57 more effortless and convenient. On the other hand, the shape of lever 561 is easy for the user to grip and operate, which helps the user control the rotation angle.

[0050] Please see Figures 3 to 4 , Figures 7 to 9 In some embodiments, the end of lever 561 away from rotating member 57 is configured to receive driving force for rotation toward the bottom of battery holder 13. Lever 561 drives rotating member 57 to overcome the gravity of battery 30 to lift connector 33 and drive connector 33 to move from locked position 501 to unlocked position 503.

[0051] Specifically, when the user applies a force to the lever 561 toward the bottom of the battery holder 13, the user's force is transmitted to the rotating member 57 through the lever 561. The force-applying end of the lever 561 receives the user's driving force, while the other end drives the rotating member 57 to rotate around the rotating shaft 51. The rotation of the rotating member 57 overcomes the downward force of the battery 30's gravity on the connecting member 33, causing the connecting member 33 to move upward under the guidance of the cam arc surface 53 of the mating groove 54. Figures 7 to 9 This allows the battery to slide from the locked position 501 to the unlocked position 503, separating the first electrical connector 131 and the second electrical connector 31, making it convenient for the user to remove the battery 30.

[0052] Please see Figures 2 to 4 In some embodiments, the battery holder 13 includes an inner cavity 136, a control member 56 is disposed on the outside of the inner cavity 136, and a rotating member 57 is housed inside the inner cavity 136.

[0053] Specifically, the control component 56 is located on the outside of the inner cavity 136, allowing the user to easily operate the control component 56 from the outside. The rotating component 57 is located inside the inner cavity 136, which not only protects the rotating component 57 from the influence of the external environment, but also prevents the user from directly contacting the rotating component 57 during operation, thereby improving the safety of using the water-based mobile equipment 1000.

[0054] Please see Figures 3 to 4 In some embodiments, the rotating shaft 51 connects the control member 56 and the rotating member 57.

[0055] Specifically, the rotating shaft 51 connects the control component 56 and the rotating component 57, so that the force of the control component 56 can be directly transmitted to the rotating component 57, reducing energy loss and ensuring synchronous movement of the two.

[0056] Please see Figures 2 to 4 In some embodiments, the control member 56 and the rotating member 57 are driven by a transmission mechanism to drive the rotating member 57 to rotate around the rotating shaft 51.

[0057] Specifically, the transmission mechanism is used to drive the rotating component 57 to rotate around the rotating shaft 51. The transmission mechanism can adjust the transmission ratio as needed to achieve effortless operation of the control component 56 or change the speed of movement.

[0058] Please see Figure 4 In some embodiments, the control member 56 includes a first helical tooth surface 563, and the rotating member 57 includes a second helical tooth surface 571, with the first helical tooth surface 563 and the second helical tooth surface 571 meshing.

[0059] Specifically, the first helical tooth surface 563 and the second helical tooth surface 571 mesh with each other, which can prevent the control member 56 and the rotating member 57 from slipping during transmission, and the control member 56 and the rotating member 57 can rotate synchronously. The meshing of the first helical tooth surface 563 and the second helical tooth surface 571 can also increase the meshing contact area, thereby dispersing stress and enhancing the load-bearing capacity and durability of the control member 56 and the rotating member 57.

[0060] Please see Figures 3 to 4 In some embodiments, the connecting assembly 50 is provided with a cover plate 55. The battery holder 13 is provided with an elastic member 135 for connecting the connecting assembly 50. When the connecting member 33 is disengaged from the connecting assembly 50, the elastic member 135 drives the connecting assembly 50 to move from the unlocked state along the first rotation direction R1. Figure 2 After being locked ( Figure 3 Turn to the closed position. Figure 4 When the connecting component 50 is rotated to the closed state, the cover plate 55 covers the first electrical connector 131, and the connecting component 50 rotates from the unlocked state to the closed state along the first rotation direction R1 and then to the locked state.

[0061] Specifically, the function and position of the cover plate 55 are consistent with the previous description and will not be repeated. When the connector 33 disengages from the connecting assembly 50, the elastic element 135 drives the connecting assembly 50 to rotate along the first rotation direction R1 from the unlocked state through the locked state to the closed state. In the unlocked state, the elastic element 135 is in a stretched state and is relatively long; as the connecting assembly 50 rotates along the first rotation direction R1, the elastic element 135 gradually contracts and its length shortens; when the connecting assembly 50 rotates to the closed state, the elastic element 135 contracts to its shortest length, and its elastic force causes the cover plate 55 to close onto the first electrical connector 131. Thus, through the natural contraction of the elastic element 135, the connecting assembly 50 can automatically rotate and automatically close the cover plate 55, improving the convenience of operation and reducing the manual operation steps of the user.

[0062] Please see Figures 5 to 9 In some embodiments, the connecting component 50 has a first rotation angle a1 and a second rotation angle a2 adjacent to the first rotation angle a1. When the connecting component 50 is within the first rotation angle a1, the elastic force of the elastic member 135 drives the connecting component 50 to rotate toward the unlocked state. When the connecting component 50 is within the second rotation angle a2, the elastic force of the elastic member 135 drives the connecting component 50 to rotate toward the locked state or the closed state.

[0063] Specifically, within the first rotation angle a1, the elastic element 135 is in a stretched state. The elastic force of the elastic element 135 can pull the connecting assembly 50 to rotate towards the unlocked state. The elastic force is transmitted to the rotating element 57 through the transmission mechanism of the connecting assembly 50, such as a lever 561 or a gear, causing the rotating element 57 to rotate in the unlocking direction. The stretching length of the elastic element 135 along the second direction L2 is greater than the stretching length along the first direction L1, and the stretching length of the elastic element 135 along the second direction L2 is greater than the stretching length along the third direction L3. Therefore, within the second rotation angle a2, the elastic element 135 gradually shortens, changing from the stretching length in the first direction L1 to the stretching length in the third direction L3, and the elastic element 135 pulls the connecting assembly 50 to rotate towards the locked and closed states.

[0064] Please see Figure 10 In some embodiments, the connecting assembly 50 is provided with a guide ramp 58 adjacent to the unlock position 503. The guide ramp 58 is configured to guide the connector 33 away from the unlock position 503 from the connecting assembly 50 and drive the connecting assembly 50 to rotate from a first rotation angle a1 to a second rotation angle a2.

[0065] Specifically, the guide ramp 58 can be part of the connecting assembly 50. For example, the guide ramp 58 can be adjacent to the loading / unloading opening 541. The guide ramp 58 and the insertion direction S have a certain angle. The guide ramp 58 has a guiding function. When it is necessary to remove the battery 30 from the battery holder 13, when the connector 33 approaches the unlock position 503, the guide ramp 58 abuts against the connector 33. During the upward lifting of the battery 30 along the insertion direction S, the connector 33 presses down on the guide ramp 58, causing the connecting assembly 50 to rotate along the first rotation direction R1. The elastic member 135 is in a stretched state, pulling the connecting assembly 50 from the first rotation angle a1 to the second rotation angle a2. Thus, the connecting assembly 50 can automatically reset to the closed state after the connector 33 is disengaged.

[0066] Please see Figure 11 In some embodiments, the connecting assembly 50 has an insertion guide surface 59 adjacent to the unlock position 503. The insertion guide surface 59 is configured to guide the connector 33 to slide toward the unlock position 503 and drive the connecting assembly 50 to rotate from the closed state to the locked state. The rotation of the connecting assembly 50 from the closed state to the locked state is configured to drive the cover plate 55 to open the first electrical connector 131, allowing the second electrical connector 31 to be inserted into the first electrical connector 131.

[0067] Specifically, the insertion guide surface 59 guides the connector 33 to slide towards the unlocked position 503 and drives the connecting assembly 50 to rotate from the closed state to the locked state. When the connecting assembly 50 is in the closed state, the cover 55 is in the closed state to protect the first electrical connector 131. When the user needs to insert the battery 30 into the battery holder 13, the connector 33 slides along the insertion guide surface 59 and presses down on the connecting assembly 50, causing the connecting assembly 50 to rotate in the opposite direction of the first rotation direction R1, driving the cover to open. When the connecting assembly 50 rotates to the unlocked position 503, the connector 33 on the battery 30 contacts the insertion guide surface 59, and the inclined surface of the insertion guide surface 59 guides the connector 33 to slide downwards along the inclined surface, gradually moving towards the unlocked position 503. At the same time, this process drives the connecting assembly 50 to start rotating, switching from the closed state to the locked state. During the rotation, the elastic element 135 may be compressed or stretched, storing elastic potential energy. When the connecting assembly 50 rotates to the locked position 501, the elastic force of the elastic member 135 drives the connecting assembly 50 to rotate further to the locked state. At this time, the cover plate 55 opens, exposing the first electrical connector 131, so that the second electrical connector 31 can be smoothly inserted into the first electrical connector 131 to complete the electrical connection.

[0068] Please see Figure 14 In some embodiments, the connecting component 50 is rotatably configured on the side of the rotating shaft 51 near the insertion position of the first electrical connector 131 and the second electrical connector 31, and the locked position 501 is further away from the rotating shaft 51 than the unlocked position 503.

[0069] Specifically, when the connecting component 50 switches from the locked state to the unlocked state, it rotates around the rotation axis 51 towards the direction closer to the rotation axis 51 to the unlocked position 503. During the rotation, the motion trajectory and force application of the connecting component 50 change, causing the direction of the force exerted by the connecting component 50 on the battery 30 to change in the unlocked position 503, generating an upward component force. This pushes the battery 30 out in the height direction Z, making it easier for the user to remove the battery 30 after unlocking. This reduces the friction and adsorption between the battery 30 and the battery holder 13, lowers the difficulty for the user to manually remove the battery 30, and improves the convenience and efficiency of battery 30 removal.

[0070] Please see Figure 12 and Figure 13 In some embodiments, the battery holder 13 is provided with a spring member 132. The spring member 132 elastically abuts against the battery 30, the connecting assembly 50 is in the unlocked position 503, and the elastic force of the spring member 132 drives the second electrical connector 31 of the battery 30 to separate from the first electrical connector 131.

[0071] Specifically, the elastic member 132 provides an elastic force to separate the second electrical connector 31 from the first electrical connector 131. When the second electrical connector 31 and the first electrical connector 131 are inserted, i.e., when the connecting assembly 50 is in the locked state, the elastic member 132 is in a compressed state, accumulating elastic potential energy. When the connecting assembly 50 switches from the locked state to the unlocked state, the battery 30 rises along the insertion direction S, and the elastic member 132 releases its elastic potential energy to drive the second electrical connector 31 of the battery 30 to separate from the first electrical connector 131 of the battery holder 13. This allows the battery 30 to move in the opposite direction of the insertion direction S under the push of the elastic member 132, thereby achieving the separation of the second electrical connector 31 from the first electrical connector 131 and ejecting the battery 30 after unlocking, improving the convenience of battery 30 removal.

[0072] Please see Figure 2 , Figure 15 and Figure 16 In some embodiments, the battery holder 13 further includes a first guide 137 extending along the mounting direction of the battery 30, and the battery 30 further includes a second guide 35. The first guide 137 and the second guide 35 cooperate to limit the mounting direction of the battery 30.

[0073] Specifically, in one example, the first guide 137 is a guide rib that extends along the mounting direction of the battery 30 (i.e., the insertion direction S), while the second guide 35 is a groove 139 (i.e., a guide slot) disposed on the battery 30. The groove 139 of the second guide 35 can further reduce the weight of the battery 30. When the battery 30 is inserted into the battery holder 13, i.e. from... Figure 16 (a) to Figure 16 (b) The first guide 137 and the second guide 35 slide into each other under the action of gravity and gradually tighten the gap. Thus, on the one hand, the battery 30 is guided to be inserted in the insertion direction S, and on the other hand, it also has a limiting function. The second guide 35 is housed in the first guide 137, which can limit the relative positional relationship between the battery 30 and the battery holder 13, and can also enhance the connection stability between the battery 30 and the battery holder 13, preventing unnecessary displacement or loosening of the battery 30 during use.

[0074] Please see Figure 17 In some embodiments, the main body 10 includes a head section 101, a shaft 103, and an underwater section 105. The head section 101 includes a battery holder 13 and a battery 30 mounted on the battery holder 13. The shaft 103 connects the head section 101 and the underwater section 105. The underwater section 105 includes an underwater housing 70, a motor 80 mounted on the underwater housing 70, and a propeller 90 connected to the motor 80.

[0075] Specifically, a motor 80 is mounted on the main body 11, and a battery 30 is configured to supply power to the motor 80. A propeller 90 is mounted on the main body 11 and connected to the motor 80, which drives the propeller 90 to rotate and generate propulsion. When the battery 30 is mounted on the battery holder 13, electrical energy is transmitted to the motor 80 through the connection of the first electrical connector 131 and the second electrical connector 31. The motor 80 converts the electrical energy into mechanical energy, driving the propeller 90 to rotate. The rotation of the propeller 90 generates propulsion in the water, thereby propelling the water carrier 300 to move in the water.

[0076] Please see Figure 17 In some embodiments, the water propulsion device 100 further includes a clamp 60, which includes a fixed bracket 61 and a rotating bracket 63. The fixed bracket 61 is fixed to the stern plate of the water carrier 300 by a fixing clamp. The main body 10 is rotatably connected to the rotating bracket 63 via a steering shaft 67, so that the main body 10 can be steered. The shaft 103 is provided with a steering bracket 40, which is rotatably connected to the steering shaft 67 on the rotating bracket 63.

[0077] Specifically, by adjusting the rotating bracket 63, the user can change the propulsion direction of the water propulsion unit 100, thereby controlling the course of the water carrier 300 to adapt to different navigation needs.

[0078] Please see Figure 17 In some embodiments, the rotating bracket 63 is rotatably connected to the fixed bracket 61 via the lifting shaft 65, and the rotating bracket 63 can be tilted and rotated relative to the fixed bracket 61 around the lifting shaft 65.

[0079] When it is necessary to adjust the angle of the water thruster 100 to adapt to different water depths or navigation conditions, the rotating bracket 63 can tilt relative to the fixed bracket 61 around the tilting shaft 65, thereby improving the adaptability and safety of the water thruster 100.

[0080] Please see Figure 2 In some embodiments, the end of the battery 30 away from the battery holder 13 is provided with a handle 37, which is configured to allow the battery 30 to be lifted manually.

[0081] Specifically, in the height direction Z, a handle 37 is provided at the end of the battery 30 away from the battery holder 13. The handle 37 makes it easier for the user to manually lift the battery 30, making the installation and removal of the battery 30 more convenient. When it is necessary to replace the battery 30 or perform maintenance, the user can use the handle 37 to lift the battery 30 without additional tools or complicated operations.

[0082] Please see Figure 2In some embodiments, the battery surface is provided with a boss 39, the battery holder 13 is provided with a groove 139 that mates with the boss 39, the first electrical connector 131 is disposed in the groove 139, and the second electrical connector 31 is disposed in the boss 39.

[0083] Specifically, in some embodiments, the battery surface is the surface of the battery 30. This design ensures that when the battery 30 is inserted into the battery holder 13, the boss 39 engages with the groove 139, guaranteeing a secure connection between the battery 30 and the battery holder 13. The first electrical connector 131 and the second electrical connector 31 are respectively disposed on the groove 139 and the boss 39. The engagement of the boss 39 with the groove 139 helps guide the correct installation direction of the first electrical connector 131 and the second electrical connector 31, making it easy to align the first electrical connector 131 and the second electrical connector 31 during battery 30 insertion, thereby ensuring stable power transmission.

[0084] Please see Figure 2 In some embodiments, the boss 39 is disposed on one side of the battery 30 in the insertion direction S, and the second electrical connector 31 is disposed on the side of the boss 39 parallel to the bottom surface of the battery 30.

[0085] Specifically, the second electrical connector 31 is disposed on the side of the boss 39 parallel to the bottom surface of the battery 30, which can ensure that the boss 39 can support the second electrical connector 31 during the insertion of the battery 30 and prevent the second electrical connector 31 from sliding.

[0086] Please see Figure 3 or Figure 4 In some embodiments, the first electrical connector 131 and the second electrical connector 31 are pluggable. At least one of the first electrical connector 131 and the second electrical connector 31 is provided with a first damping member 1315, which provides pluggable damping for the first electrical connector 131 and the second electrical connector 31.

[0087] Specifically, the first damping element 1315 provides appropriate damping force during the insertion of the battery 30. This damping force helps ensure a more stable and reliable connection between the electrical connectors 33, preventing loosening due to vibration or other external factors. Simultaneously, the presence of the first damping element 1315 also buffers the impact force during battery insertion to a certain extent, protecting the first and second electrical connectors 131 from bumps and damage, and extending their service life. Furthermore, the resistance provided by the first damping element 1315 also provides users with a better operating feel, making the insertion operation smoother and more precise, further improving the reliability and overall performance of the electrical connection. For example, Figure 3 or Figure 4 In this embodiment, the first damping element 1315 is disposed at the periphery of the insulating base portion 1311 of the first electrical contact 131. In other embodiments, the first damping element 1315 may be of other numbers or in other locations.

[0088] Please see Figure 3 or Figure 4 In some embodiments, the first damping element 1315 is configured as an elastic sealing ring.

[0089] Specifically, the elastic sealing ring prevents external water, dust, and other impurities from entering the gap between the first electrical connector 131 and the second electrical connector 31, improving the reliability and service life of the connection. The elastic sealing ring is low in cost and easy to install and maintain.

[0090] Please see Figure 2 In some embodiments, the outer casing of the battery 30 and the housing of the battery holder 13 are pluggable. At least one of the outer casing of the battery 30 and the housing of the battery holder 13 is provided with a second damping member 36, which provides damping for the pluggable connection between the outer casing of the battery 30 and the housing of the battery holder 13.

[0091] Specifically, the outer casing of the battery 30 and the casing of the battery holder 13 are designed for plug-in mating, meaning that the battery 30 and the battery holder 13 can be plugged in and out through mutually matching structures. Plug-in mating includes, but is not limited to, snap-fit ​​connections, slide rail connections, and plug-and-socket connections, etc. At least one of the outer casing of the battery 30 and the casing of the battery holder 13 is provided with a second damping member 36. Exemplarily, the second damping member 36 of this application is disposed on the side wall of the second guide member 35 of the battery 30. In other embodiments, the second damping member 36 may be of other numbers or in other locations. The second damping member 36 provides plug-in damping, giving appropriate resistance during the insertion or removal of the battery 30, ensuring smooth plugging and removing the battery and preventing unreliable connections. The second damping member 36 also enhances connection stability, preventing the battery 30 from accidentally loosening or falling off due to vibration or other external forces, ensuring a secure connection. The second damping member 36 also buffers and absorbs shocks, reducing mechanical damage and extending the service life of the battery 30.

[0092] Please see Figure 2 In some embodiments, the first electrical connector 131 is provided with a first DC positive terminal and a first DC negative terminal, and the second electrical connector 31 is provided with a second DC positive terminal and a second DC negative terminal. When the first electrical connector 131 and the second electrical connector 31 are electrically connected, the first DC positive terminal is connected to the second DC negative terminal, and the first DC negative terminal is connected to the second DC positive terminal.

[0093] Specifically, the first DC positive terminal is connected to the second DC negative terminal, and the first DC negative terminal is connected to the second DC positive terminal, thus forming a complete electrical circuit. Electrical energy can flow from the battery 30 to the motor 80, thereby providing power to the motor 80 of the water propulsion device 100.

[0094] Please see Figure 2 In some embodiments, the first electrical connector 131 is provided with a first communication line. The second electrical connector 31 is provided with a second communication line, and when the first electrical connector 131 and the second electrical connector 31 are electrically connected, the first communication line and the second communication line are electrically connected.

[0095] Specifically, the first communication line is electrically connected to the second communication line, so that the battery 30 and the motor 80 can not only transmit electrical energy, but also communicate data. The battery 30 can also feed back operating information, such as the remaining power and temperature of the battery 30, to the motor 80 or other components of the water propulsion unit 100 (such as the controller) through the communication line, so as to manage the battery 30.

[0096] Please see Figure 2 In some embodiments, the insertion direction S of the battery 30 is inclined to the length direction of the main body 11.
