Description

Technical Field

[0001] This invention relates to the field of water equipment technology, and in particular to a water propulsion device and a water mobile device. Background Technology

[0002] In the application scenarios of electric outboard motors, the battery system needs to adapt to frequent replacements and convenient user operation, and the battery removal method directly affects the user experience. Traditional battery installation methods have obvious limitations. Some battery installation and removal methods are inefficient, such as threaded fastening methods, which use screws for fixing, rely on tools, and involve many steps, making installation and removal cumbersome and time-consuming. Another example is the traditional snap-on method, which uses a snap-on structure, requiring the physical snap-on to be released before disconnecting the power interface, thus lengthying the battery replacement time. Some battery installation and removal methods have poor reliability. For example, manual locking designs rely on manual alignment and are easily affected by the water environment. In the turbulent environment of the water, positioning deviations can easily lead to installation and removal failures. Long-term vibration may also cause the mounting mechanism to accidentally disengage, and there is even a risk that the battery may fall off, threatening user safety. Some battery installation and removal methods offer a poor user experience. For example, the sliding rail snap-on design requires precise alignment with the rail groove, and the rails are prone to jamming due to seawater corrosion. Furthermore, both hands are needed for disassembly, resulting in a poor user experience. Other electric outboard motors require tools for quick-release battery installation and removal, leading to lengthy installation and removal times. Ordinary users sometimes lack the necessary tools, making battery installation and removal impossible, further negatively impacting the user experience. These shortcomings highlight the difficulty of balancing reliability, environmental adaptability, and ease of operation with current technologies. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In this application, the water-based mobile device 1000 may include various water transportation vehicles such as passenger ships, yachts, cruise ships, sailboats, ships, unmanned patrol boats, and waterborne drones. The water-based mobile device 1000 may include a water-based carrier 1100 and a water-based propulsion device 100. The water-based carrier 1100 may be a hull, and the water-based propulsion device 100 may be, for example, an outboard motor, and the water-based propulsion device 100 is mounted on the water-based carrier.

[0024] Please see Figure 1 , Figure 1 This is a partial structural diagram of a water propulsion device provided in an embodiment of the present invention. The water propulsion device 100 includes: a battery 10, a mounting base 20, and a snap-fit ​​connection structure 30. The battery 10 is pluggable into the mounting base 20, allowing the battery 10 to be charged and discharged through the mounting base 20. The snap-fit ​​connection structure 30 includes an operating member 310, a swing rod 320, and a stop structure 330. The operating member 310 is rotatably connected to the battery 10, the swing rod 320 is rotatably connected to the operating member 310, and the stop structure 330 is fixed on the mounting base 20. The stop structure 330 is provided with a slot 331, and the operating member 310 is provided with a hook 311 that can be engaged with the slot 331. The operating member 310 can be rotated relative to the battery 10 to a first position S1, a second position S2, and a third position S3 in sequence. like Figure 10 As shown, when the operating member 310 is rotated to the first position S1, the hook 311 engages with the slot 331, the battery 10 is inserted into the mounting base 20, the swing rod 320 rotates relative to the operating member 310 to the middle position and separates from the stop structure 330, and is allowed to rotate to the first extreme position.

[0025] Figure 10 The image shows the battery in the installed state, which can be locked by the hook 311 engaging with the slot 331.

[0026] like Figure 11 As shown, when the operating member 310 is rotated to the second position S2, the hook 311 separates from the slot 331, the battery 10 is inserted into the mounting base 20, and the swing rod 320 rotates relative to the operating member 310 to the first limit position and abuts against the first fulcrum of the stop block structure 330.

[0027] In this process, the user can push the operating component, and the hook 311 of the operating component gradually disengages from the slot 331 until the swing rod 320 contacts the top of the stop structure 330. At this time, a lever structure is formed between the stop structure 330, the operating component 310, and the swing rod 320.

[0028] like Figure 12 As shown, when the operating member 310 is rotated to the third position S3, the battery 10 is disengaged from the mounting base 20, the swing rod 320 is held in the first limit position relative to the operating member 310, and the swing rod 320 abuts against the second fulcrum of the stop block structure 330. The second fulcrum is closer to the battery 10 relative to the first fulcrum.

[0029] Wherein, battery 10 detaching from mounting base 20 means that battery 10 and mounting base 20 are completely separated, or at least partially separated, such as... Figure 12 As shown, the battery 10 is partially separated from the mounting base 20, for example, the first connector 110 of the battery 10 and the second connector 220 of the mounting base 20 are separated; then the user can lift the battery 10 by the handle to completely separate the battery 10 from the mounting base 20.

[0030] Specifically, after the stop structure 330, the operating member 310, and the swing rod 320 form a lever structure, with the assistance of the lever structure, the user can continue to push the operating member 310 to pry the battery 10, causing the first connector 110 of the battery 10 to separate from the second connector 220 of the mounting base 20; after the first connector 110 and the second connector 220 are separated, the user can continue to lift the battery 10 to safely remove the battery 10.

[0031] like Figure 2 As shown, the stop structure 330 is fixedly connected to the mounting base 20, the operating member 310 is rotatably connected to the swing rod 320, and the operating member 310 is rotatably connected to the battery 10. The user can hold the battery 10 and move the operating member 310 to install the battery 10 to the mounting base 20. When removing the battery 10, the user can move the operating member 310, and through the cooperation of the operating member 310 and the swing rod 320, the battery 10 can be detached from the mounting base 20.

[0032] When the user removes the battery 10, the operating component 310 can be moved. The hook 311 of the operating component 310 gradually disengages from the slot 331 until the swing rod 320 contacts the top of the stop structure 330, thereby forming a lever structure between the swing rod 320 and the operating component 310. The user can continue to push the operating component 310 to pry the battery 10, thereby separating the first connector 110 from the second connector 220 and safely removing the battery 10. Since the swing rod 320 and the operating component 310 form a lever structure, the user saves effort in removing the battery 10 and can easily overcome the damping force of the insertion of the first connector 110 and the second connector 220, thus facilitating the removal and disassembly of the battery 10.

[0033] Optionally, such as Figure 2 As shown, the stop block structure 330 is provided with a reset groove 332, which is located on the side of the second fulcrum away from the first fulcrum. The operating member 310 can also be rotated to the fourth position S4 relative to the battery 10. The fourth position S4 is located on the side of the third position S3 away from the second position S2. like Figure 14 As shown, when the operating member 310 is rotated to the fourth position, the swing arm 320 rotates to the middle position relative to the operating member 310, and the swing arm 320 is aligned with the reset groove 332. The reset groove 332 allows the swing arm 320 to move and be inserted into the mounting base 20 along with the battery 10.

[0034] like Figure 13 As shown, this is the state where the user is preparing to install the battery. The user can rotate the operating component 310 to align the swing rod 320 with the reset groove 332, allowing the swing rod 320 to enter the reset groove 332. The reset groove 332 is inclined, which guides the swing rod 320 to move towards the abutment wall 333 connected to the reset groove 332, until the swing rod 320 gradually moves towards the battery 10 and retracts, and can move downward along the abutment wall 335, so that the battery 10 can move downward and be inserted into the mounting base 20. When the battery 10 is inserted into the mounting base 20, that is, when the first connector of the battery 10 is in place... After the second connector 220 of the mounting base 20 is inserted into the position, the user releases the operating member 310. Under the reset action of the elastic member, the operating member 310 will rotate to the first position S1, thereby driving the swing rod 320 to move upward along the reset groove until the swing rod 320 moves to the position of returning to the reset groove 332. Since the swing rod 320 loses the limit of the blocking wall 335, the swing rod 320 resets under the elastic force of the elastic member until the swing rod 320 disengages from the reset groove 332. At this time, the latch of the operating member and the latch of the stop block structure engage, so that the battery enters the locked state.

[0035] Optionally, such as Figures 3-7As shown, the snap-fit ​​connection structure 30 also includes a first elastic member 301, a first connecting member 302, and a second connecting member 303. The operating member 310 includes a first connecting portion 312 and a second connecting portion 313. The swing rod 320 includes a third connecting portion 321. The first end of the first elastic member 301 is connected to the first connecting portion 312 and the third connecting portion 321 through the first connecting member 302, that is, one end of the first elastic member 301 is connected to the operating member 310. The second end of the first elastic member 301 is connected to the second connecting portion 313 through the second connecting member 303, that is, the other end of the first elastic member 301 is connected to the swing rod 320.

[0036] The operating member 310 and the swing rod 320 can be connected to the first elastic member 301, the first connecting member 302, and the second connecting member 303, so that the operating member can drive the swing rod 320 to rotate.

[0037] The first elastic element 301 can be, for example, a tension spring. When the external force is removed from the swing arm 320, the elastic element of the first elastic element 301 can drive the swing arm to return to its original position and maintain the angle defined with the operating member 310. When the angle between the swing arm 320 and the operating member 310 opens, the first elastic element 301 is stretched; when the angle between the swing arm 320 and the operating member 310 contracts, the first elastic element 301 is compressed.

[0038] Optionally, the first connecting portion 312 is a first connecting hole, the second connecting portion 313 includes two spaced second connecting holes 313a, the third connecting portion 321 is a third connecting hole, the first connecting member 302 is a first pin, the second connecting member 303 is a second pin, the first pin passes through the first connecting hole and the third connecting hole, the second pin passes through the two spaced second connecting holes 313a, the first end of the first elastic member 301 is sleeved on the first pin, and the second end of the first elastic member 301 is sleeved on the second pin.

[0039] like Figure 6 As shown, the second connecting part 313 includes two spaced second connecting holes 313a. The first pin passes through the two second connecting holes 313a in sequence. The first end of the first elastic member 301 is sleeved on the first pin and is located in the space between the two second connecting holes 313a.

[0040] In addition to being pins, the first connector 302 and the second connector 303 can also be other fasteners.

[0041] Optionally, the operating member 310 includes two parallel levers 314 and an operating part 315 disposed between the two levers, wherein the free end of the lever 314 is provided with a hook 311.

[0042] Optionally, the operating part 315 is a rotary handle or a toggle handle.

[0043] like Figure 3 As shown, the operating part 315 is a toggle handle. The user can toggle the operating part 315 to rotate the operating member 310, thereby driving the swing arm 320 to rotate.

[0044] Optionally, such as Figure 2 As shown, the reset groove 332 of the stop block structure 330 includes a vertical groove wall 333 and a stop wall 334 on both sides of the groove wall. The stop wall 334 is inclined downward from the upper end of the stop block structure 330. The slot 331 includes two slots, which are located near the stop walls 334 on both sides of the reset groove 332.

[0045] By setting two slots 331, they can engage with the two hooks 311 of the operating component 310, so that the battery is kept stable after it is inserted, thereby making the first connector 110 and the second connector 220 firmly connected.

[0046] Optionally, a clearance space 335 is formed in the middle of the stop structure 330, the battery 10 includes a first connector 110, and the mounting base 20 is provided with a second connector 220. The first connector 110 and the second connector 220 are used to insert when the battery 10 is installed, and the second connector 220 is located in the clearance space 335.

[0047] By forming a clearance space 335 in the middle of the stop structure 330 to accommodate the second connector 220, the stop structure 330 and the second connector 220 are made compact, which also facilitates the tight insertion of the first connector 110 and the second connector 220 after the battery is inserted.

[0048] When the battery 10 is installed, after the battery 10 is locked to the mounting base 20, the first connector 110 and the second connector 220 are aligned and inserted. When the battery is removed, as the battery 10 is removed from the mounting base 20, the first connector 110 and the second connector 220 can be disengaged.

[0049] Optionally, such as Figure 1 , Figure 3 and Figure 5As shown, the battery 10 includes a battery head block 120 and a battery body 130, which are fixedly connected. The snap-fit ​​connection structure 30 further includes a second elastic member 304, a third connecting member 305, and a fourth connecting member 306. The operating member 310 includes a fourth connecting portion 316, and the battery head block 120 includes a fifth connecting portion 121 and a sixth connecting portion 122. The first end of the second elastic member 304 is connected to the fourth connecting portion 316 and the fifth connecting portion 121 through the third connecting member 305, that is, one end of the second elastic member 304 is connected to the operating member 310; the second end of the second elastic member 304 is connected to the sixth connecting portion 122 through the fourth connecting member 306, that is, the other end of the second elastic member 304 is connected to the battery head block 120.

[0050] The operating member 310 is rotatably connected to the battery head block 120. The second elastic member 304 can be, for example, a tension spring. By providing the second elastic member 304, the operating member 310 and the battery head block 120 are connected through the second elastic member 304, the third connecting member 305, and the fourth connecting member 306. Thus, when the battery 10 is installed or removed, the battery head block 120 can drive the operating member 310 to rotate, thereby driving the swing rod 320 to rotate. When the operating member 310 is away from the first position S1, if the external force is removed, the second elastic member 304 can drive the operating member 310 to return to the first position S1, so that the hook 311 can quickly engage with the slot 332.

[0051] When installing battery 10, by moving the operating member 310, the swing rod 320 is aligned with the reset groove 332, and the swing rod 320 can enter the reset groove 332. After the user releases the operating member 310, the operating member 310 is subjected to the force of the second elastic member, and the operating member 310 resets to the first position S1. The operating member 310 drives the swing rod 320 to move upward along the reset groove 332 until the swing rod 320 disengages from the reset groove 332. At this time, the operating member 310 is subjected to the force of the first elastic member, so that the hook 311 of the operating member 310 engages with the slot 331 of the stop structure 330, thereby locking the battery 10. At the same time, the first connector 110 and the second connector 220 are connected.

[0052] When removing the battery 10, the user pushes the operating component 310, and the hook 311 of the operating component 310 gradually disengages from the slot 331. The swing rod 320 rotates with the operating component 310 until the swing rod 320 contacts the top of the stop structure 330. At this time, the swing rod 320 and the operating component 310 form a lever structure, and the operating component 310 no longer rotates relative to the battery head block 120. The user continues to push the operating component 310, and the torque force of the operating component 310 is converted into the upward linear motion force of the battery head block 120, that is, the battery 10 can drive the first connector 110 to separate from the second connector 220.

[0053] Optionally, the fourth connecting part 316 is a fourth connecting hole, the fifth connecting part 121 is a fifth connecting hole, the sixth connecting part 122 is a sixth connecting hole, the third connecting member 305 is a first plug screw, the fourth connecting member is a third pin, the first plug screw passes through the fourth connecting hole and the fifth connecting hole, the third pin passes through the sixth connecting hole, the first end of the second elastic member 304 is sleeved on the first plug screw, and the second end of the second elastic member 304 is sleeved on the third pin.

[0054] The third connector can be a screw or other fastener; the fourth connector can be a pin or other fastener.
