Description

Technical Field

[0001] This utility model relates to the field of water transportation equipment technology, and in particular to a water vehicle and its overturning mechanism. Background Technology

[0002] Water vehicles are indispensable tools in water recreation, rescue, and fishing operations. Common water vehicles are mainly divided into two categories: hard-bottomed structures and inflatable structures.

[0003] Rigid-bottomed watercraft, such as traditional inflatable boats, offer strong impact resistance and load-bearing capacity thanks to their robust materials and stable structure, ensuring safety during use. However, this design also presents significant drawbacks. Due to their rigidity, they cannot be folded and stored when not in use, resulting in them occupying a considerable amount of space. For home users, finding suitable storage space within their residences is difficult; for surfers, fishing enthusiasts, and other users who need to carry these vehicles for outdoor activities, their excessive size makes transportation extremely difficult. Ordinary family vehicles simply cannot accommodate them, requiring specialized transport, which not only increases transportation costs but also significantly reduces ease of use.

[0004] Inflatable watercraft, such as the common inflatable boat, effectively solve the storage and transportation problems of rigid-bottomed vehicles. When not in use, they can be deflated and folded, resulting in a compact size that is easy to carry and store, greatly improving transportation convenience. However, these vehicles also have their limitations. Because their main structure is inflatable, they lack a solid deck, which significantly restricts personnel standing and the placement of items during use. Their stability is also relatively poor, making it difficult to meet the needs of some scenarios requiring operation on the vehicle, such as placing fishing gear during fishing operations or ensuring stable standing for personnel during rescue operations, thus affecting their performance to some extent.

[0005] In view of the inconvenience of storing and transporting fully rigid structure vehicles, and the problem that the lack of a deck for inflatable structure vehicles restricts their use, this application provides a structurally stable and easy-to-store water vehicle and its overturning mechanism.

[0006] Therefore, the existing technology still needs to be improved and enhanced. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a water vehicle with a stable structure and convenient storage, and its flipping mechanism.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A tilting mechanism for a watercraft includes: a fixed base fixedly connected to the main body of the watercraft; an adjusting rod disposed on the fixed base and capable of axial position adjustment along its own setting direction; and a tilting component connected to a side deck of the watercraft and disposed on the fixed base via a spindle, the spindle being parallel to the adjusting rod. The adjusting rod is adjusted axially, and the tilting component drives the side deck to rotate around the spindle, thereby unfolding the side deck to be flush with the main body or folding the side deck to the side of the main body.

[0009] The adjusting rod is arranged longitudinally relative to the water vehicle, and the adjusting rod has a clearance part arranged along its circumference. The clearance part corresponds to the flipping member, and the flipping member can rotate around the spindle.

[0010] The flipping component is provided with at least one abutting surface, the avoidance part is offset from the flipping component along the axial direction, and the outer periphery of the adjusting rod is adapted to the abutting surface to restrict the flipping component from rotating around the spindle.

[0011] The adjusting rod is threaded into the fixed seat to allow the adjusting rod to be axially adjusted along its own setting direction; the first connecting rod and the second connecting rod are not on the same plane.

[0012] The overturning mechanism of the watercraft also includes an adjustment assembly, which is mounted on the main body via a mounting base. The adjustment assembly includes a wrench and a connecting rod. The wrench is hinged to the mounting base, one end of the connecting rod is connected to the wrench, and the other end of the connecting rod is connected to the adjustment rod. The adjustment rod is slidably engaged with the fixed base. When the wrench is rotated, the connecting rod drives the adjustment rod to adjust its axial position along its own setting direction.

[0013] A watercraft includes: a main body, the main body comprising a first part located at the front end of the watercraft and a second part located at the rear end of the watercraft, the first part and the second part being capable of flipping relative to each other along the thickness direction of the main body; side decks located on both sides of the first part and the second part, and a flipping mechanism of the watercraft is provided below the side decks for the side decks to flip on the sides of the first part and the second part; and an inflation module located below the side decks.

[0014] The first part and the second part are hinged by a linkage assembly to limit the flipping of the first part and the second part.

[0015] The linkage assembly includes a first linkage and a second linkage. The motion planes of the first linkage and the second linkage are parallel to the sides of the main body, and the motion planes of the first linkage and the second linkage do not coincide. The axes of the hinged portions at both ends of the first linkage and the hinged portions at both ends of the second linkage do not coincide.

[0016] The main body is provided with a locking assembly to limit the unfolded state of the first part and the second part when they are flush; the locking assembly includes a base, a handle, a latch, and a locking element. The base is disposed on the second part and is hinged to the handle. One end of the latch is hinged to the handle, and the other end of the latch is used to engage with the locking element on the first part.

[0017] When the side deck of the first part is flipped to the side of the first part and the side deck of the second part is flipped to the side of the second part, a gap space is defined between the side deck of the first part and the side deck of the second part to accommodate the deflated inflation module.

[0018] Compared to existing technologies, this utility model provides a watercraft and its overturning mechanism. The overturning mechanism of the watercraft includes: a fixed base, which is fixedly connected to the main body of the watercraft; an adjusting rod, which is disposed on the fixed base and can be axially adjusted along its own setting direction; and an overturning component, which is connected to the side deck of the watercraft and is disposed on the fixed base via a spindle, the spindle being parallel to the adjusting rod. The adjusting rod is axially adjusted, and the overturning component drives the side deck to rotate around the spindle, thereby unfolding the side deck to be flush with the main body or folding the side deck to the side of the main body. The overturning mechanism of this application allows the adjusting rod to be axially adjusted along its own setting direction, so that while the overturning component rotates around the spindle, it simultaneously drives the side deck to flip on the side of the main body, thereby unfolding the side deck to be flush with the main body or folding the side deck to the side of the main body. In this application, the axial position of the adjusting rod is controlled to limit or release the tilting component, thereby quickly adjusting the tilting of the side deck. The structure is simple and the operation is convenient. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0033] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0034] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0035] This utility model provides a tipping mechanism for a watercraft. Please refer to [link / reference]. Figures 1-7The device includes: a fixed base 11, which is fixedly connected to the main body 21 of the watercraft; an adjusting rod 12, which is disposed on the fixed base 11 and can be axially adjusted along its own setting direction; and a flipping member 13, which is connected to the side deck 22 of the watercraft and is disposed on the fixed base 11 via a spindle 14, which is parallel to the adjusting rod 12. The adjusting rod 12 is axially adjusted, and the flipping member 13 drives the side deck 22 to rotate around the spindle 14, so as to unfold the side deck 22 to be flush with the main body 21 or fold the side deck 22 to the side of the main body 21.

[0036] The tilting mechanism of this application for a watercraft involves axially adjusting the adjusting rod 12 along its own setting direction. This allows the tilting component 13 to rotate around the spindle 14 while simultaneously tilting the side deck 22 to the side of the main body 21. This unfolds the side deck 22 to be flush with the main body 21 or folds it to the side of the main body 21. In this application, the axial position of the adjusting rod 12 is controlled to limit or release the tilting component 13, thereby enabling rapid tilting adjustment of the side deck 22. The structure is simple and the operation is convenient.

[0037] Specifically, when the adjusting rod 12 is axially adjusted along the first direction of movement, the flipping member 13 can rotate around the spindle 14 in the first flipping direction to flip the side deck 22 to a state flush with the main body 21; or, the flipping member 13 can rotate around the spindle 14 in the second flipping direction to fold the side deck 22 to the side of the main body 21. When the adjusting rod 12 is axially adjusted along the second direction of movement, the adjusting rod 12 limits the angle of the flipping member 13 so that the flipping member 13 cannot rotate around the spindle 14, thereby ensuring the stability of the side deck 22 after flipping in the first or second flipping direction. The first and second directions of movement are opposite and both are along the setting direction of the adjusting rod 12 itself. The first and second flipping directions are opposite and both are circumferential along the spindle 14, with the spindle 14 as the reference axis.

[0038] In this embodiment, the fixing seat 11 is fastened to the side of the main body 21 of the watercraft by screws. When the side deck 22 is unfolded to be flush with the main body 21, the fixing seat 11 is located below the side deck 22. The side deck 22 and the flipping member 13 are two relatively independent components. One end of the flipping member 13 is hinged to the spindle 14, and the other end of the flipping member 13 is fixedly connected to the lower end of the side deck 22. The adjusting rod 12 and the spindle 14 are installed in the mounting holes on the fixing seat 11. Both the adjusting rod 12 and the spindle 14 are cylindrical. The plane formed by the central axis of the adjusting rod 12 and the central axis of the spindle 14 is parallel to the end face of the main body 21. Since the fixed seat 11 is fixedly connected to the main body 21, the side plate 22 is set on the fixed seat 11 through the flipping part 13 and the spindle 14. Therefore, the flipping part 13 will synchronously drive the side plate 22 to rotate during the rotation around the spindle 14, so that the side plate 22 unfolds to be flush with the main body 21 or the side plate 22 flips to the side of the main body 21. The side plate 22 and the flipping part 13 are two relatively independent components, and the materials can be selected according to their differentiated functional requirements. For example, the side plate 22 can be made of aluminum alloy sheet, which is low in cost and easy to process. The flipping part 13 can be made of stainless steel, high-strength engineering plastics, etc., to ensure structural strength. This can meet their respective functional requirements and avoid excessive cost due to the use of expensive materials as a whole. In addition, damaged parts can be disassembled and replaced separately during later maintenance, reducing costs.

[0039] It should be noted that the side deck 22 folding to the side of the main body 21 is relative to the side deck 22 being unfolded to be flush with the main body 21. The side deck 22 folding to the side of the main body 21 refers to the position of the side deck 22 after it has been rotated 90° around the spindle 14 from the position flush with the main body 21. The purpose is to fold and store the side deck 22 of the water vehicle when it is not in use, reduce the space occupied by the side deck 22 during transportation and storage, and improve the portability and storage convenience of the water vehicle.

[0040] In addition, in some embodiments, the side deck 22 may also be integrally formed with the flipping member 13. When the flipping member 13 rotates around the spindle 14, it can synchronously drive the side deck 22 to flip, so that the side deck 22 unfolds to be flush with the main body 21 or flips the side deck 22 to the side of the main body 21. The integrally formed structure does not require additional fixed connection between the side deck 22 and the flipping member 13, resulting in higher structural strength and stability.

[0041] Furthermore, the adjusting rod 12 is arranged longitudinally relative to the water vehicle, and the adjusting rod 12 is provided with a clearance part 121 along its circumference. The clearance part 121 corresponds to the flipping member 13, and the flipping member 13 can rotate around the spindle 14.

[0042] In this embodiment, a receiving portion is provided on the side of the watercraft along its length (longitudinal direction). The receiving portion is formed by the inward indentation of the side of the watercraft. A fixing seat 11 is installed in the receiving portion and screwed to the watercraft. An adjusting rod 12 is installed on the fixing seat 11 along the setting direction of the receiving portion. The flipping mechanism is installed in the space defined by the receiving portion, which avoids the flipping mechanism occupying the core bearing area of ​​the watercraft. The longitudinal layout makes the axial adjustment path of the adjusting rod 12 consistent with the length direction of the watercraft. The operator can easily apply force along the length direction on the side of the watercraft (such as rotating the adjusting rod 12 or pushing the wrench part 152) without having to reach into the watercraft to operate, which improves the convenience of adjustment. In addition, the flipping mechanism is installed in the receiving portion to connect the main body 21 and the side deck 22. When the side deck 22 is unfolded to be flush with the main body 21 or when the side deck 22 is folded to the side of the main body 21, the structure of the two is more compact. This does not destroy the overall shape of the watercraft and ensures that the adjustment stroke meets the functional requirements. In this application, one side deck 22 corresponds to one adjusting rod 12, and a single adjusting rod 12 corresponds to at least two fixed seats 11. The fixed seats 11 provide stable support for the longitudinally arranged adjusting rod 12, preventing the adjusting rod 12 from bending and deforming when it moves axially or is subjected to the limiting reaction force of the flipping part 13, further ensuring the matching accuracy between the avoidance part 121 and the flipping part 13, and improving the operational stability of the entire flipping mechanism.

[0043] Furthermore, the adjusting rod 12 is provided with a clearance part 121 on its circumferential side facing the flipping member 13. The clearance part 121 is essentially a slot opened on the adjusting rod 12 in its circumferential direction. The opening width of the slot along the axial direction is adapted to the thickness of the flipping member 13, and the depth of the slot is sufficient to accommodate the rotation trajectory of the flipping member 13, avoiding the problem of interference caused by insufficient clearance. By adjusting the axial position of the adjusting rod 12 along its own direction, the relative position of the clearance part 121 and the flipping member 13 in the axial direction can be adjusted simultaneously. When the position of the clearance part 121 on the adjusting rod 12 corresponds to the position of the flipping member 13, the adjusting rod 12 cannot limit the flipping member 13 on its circumference. At this time, the flipping member 13 can rotate around the spindle 14. At the same time, the side deck 22 can be simultaneously unfolded to be flush with the main body or the side deck 22 can be folded to the side of the main body 21.

[0044] Furthermore, the flipping member 13 is provided with at least one abutting surface 131, the avoidance part 121 is axially misaligned with the flipping member 13, and the outer periphery of the adjusting rod 12 is adapted to the abutting surface 131 to restrict the flipping member 13 from rotating around the spindle 14.

[0045] In this embodiment, the adjusting rod 12 is axially adjusted along its own setting direction so that the clearance portion 121 of the adjusting rod 12 is opposite to the position of the flipping member 13. At this time, the deck and the flipping member 13 can rotate synchronously around the spindle 14. When the side deck 22 is unfolded to be flush with the main body 21, in order to maintain the stability of the unfolded state of the side deck 22, an abutment surface 131 is provided on the flipping member 13 so that the abutment surface 131 cooperates with the adjusting rod 12, thereby limiting the rotation of the flipping member 13 and the side deck 22 around the spindle 14. In this application, the adjusting rod 12 is cylindrical, and the abutment surface 131 is an arc surface to adapt to the outer periphery of the adjusting rod 12, and the arc corresponding to the arc surface is a minor arc.

[0046] In this application, the adjustment power (axial displacement of the adjustment rod 12) and the limiting function (the outer periphery of the adjustment rod 12 abutting against the flipping part 13) are integrated into the same component, avoiding the accumulation of errors caused by the linkage of multiple components. At the same time, after axial misalignment, the adjustment rod 12 and the abutting surface 131 are in surface contact, with a large contact area and more uniform limiting force, which can effectively disperse the external force on the flipping part 13, reduce component wear caused by local stress concentration (such as deformation of the flipping part 13 and the abutting surface 131), and extend the service life of the flipping mechanism. Preferably, in this embodiment, the flipping part 13 is provided with two abutting surfaces 131. The provision of two abutting surfaces 131 ensures that there is an abutting surface 131 that can cooperate with the adjustment rod 12 whether the side deck 22 is unfolded to be flush with the main body 21 or when the side deck 22 is flipped to the side of the main body 21, thereby ensuring the stability of the side deck 22 in two different structural states.

[0047] Furthermore, the adjusting rod 12 is threadedly engaged with the fixed base 11 so that the adjusting rod 12 can be axially adjusted along its own setting direction.

[0048] In one embodiment of this application, the adjusting rod 12 has an external thread on its outer periphery, and the mounting hole of the fixing seat 11 has a thread on its inner wall. The adjusting rod 12 is installed in the mounting hole of the fixing seat 11 by means of a threaded connection. By rotating the adjusting component, the axial position can be adjusted along the direction set by the adjusting rod 12 itself. In this embodiment, by utilizing the self-locking property of the threaded transmission, not only can the precise fine adjustment of the axial position of the adjusting rod 12 be achieved, but it can also automatically maintain its position after adjustment without the need for additional locking components, simplifying the structure while improving the convenience of operation.

[0049] The overturning mechanism of the watercraft also includes an adjustment assembly 15, which is mounted on the main body 21 via a mounting base 151. The adjustment assembly 15 includes a wrench part 152 and a connecting rod 153. The wrench part 152 is hinged to the mounting base 151. One end of the connecting rod 153 is connected to the wrench part 152, and the other end of the connecting rod 153 is connected to the adjustment rod 12. The adjustment rod 12 is slidably engaged with the fixed base 11. When the wrench part 152 is rotated, the connecting rod 153 drives the adjustment rod 12 to adjust its axial position along its own setting direction.

[0050] In another embodiment of this application, the mounting base 151 is fixed to the side of the main body 21 and close to the front or rear end of the watercraft to facilitate the user's adjustment of the wrench 152. The wrench 152 is hinged to the mounting base 151 to provide a fulcrum for the rotation of the wrench 152. One end of the wrench 152 is hinged to one end of the connecting rod 153, and the other end of the connecting rod 153 is hinged to the adjusting rod 12. The connecting rod 153 is slidably disposed in the mounting hole of the fixed base 11. When the wrench 152 is rotated, under the connecting action of the connecting rod 153 and the guiding action of the mounting hole, the force of rotating the wrench 152 will be transmitted to the adjusting rod 12 through the connecting rod 153 to push or pull the adjusting rod 12 to adjust its axial position along its own setting direction. The wrench part 152 and the mounting base 151, one end of the connecting rod 153 and the wrench part 152, and the other end of the connecting rod 153 and the adjusting rod 12 are all hinged by a pin connection; the rotation of the wrench part 152 is converted into the axial movement of the adjusting rod 12, and the operation difficulty is reduced by lever principle. Even in situations where the space of the water vehicle is limited or the operator's hands are inconvenient to apply force, the adjustment can be easily completed; the adjusting component 15 has a simple structure and is easy to operate. The axial position adjustment of the adjusting rod 12 can be quickly achieved by turning the wrench part 152, which improves the practicality of the flipping mechanism.

[0051] This utility model also provides a waterborne vehicle; please refer to [link / reference]. Figures 1-12 The system includes: a main body 21, which includes a first part 211 located at the front end of the watercraft and a second part 212 located at the rear end of the watercraft, wherein the first part 211 and the second part 212 are capable of flipping relative to each other along the thickness direction of the main body 21; a side deck 22, which is located on both sides of the first part 211 and the second part 212, and a flipping mechanism of the watercraft is provided below the side deck 22 to allow the side deck 22 to flip on the sides of the first part 211 and the second part 212; and an inflation module 23, which is located below the side deck 22.

[0052] This application is based on a reversible hard-bottom main body 21, combined with an adjustable side deck 22 and an inflatable module 23 located below the side deck 22 to form a water vehicle, which solves the problem that existing water vehicles cannot simultaneously meet the requirements of stable use and flexible folding.

[0053] Specifically, the main body 21 of the watercraft includes a first part 211 and a second part 212 that can be flipped relative to each other. The side decks 22 include a left deck and a right deck. Both sides of the first part 211 and the second part 212 are provided with left and right decks, which are connected to the first part 211 and the second part 212 via a flipping mechanism. The second part 212 can be folded 180° downwards towards the first part 211 to achieve folding and storage of the main body 21. The left and right decks of the first part 211 can be folded 90° downwards towards the first part 211 to achieve folding and storage. The left and right decks of the second part 212 can be folded 90° downwards towards the second part 212 to achieve folding and storage. The watercraft structure of this application allows for quick folding and storage, is simple to operate, reduces space occupation during transportation or storage, and improves portability.

[0054] Furthermore, the first part 211 and the second part 212 are hinged by a link assembly 213 to limit the flipping of the first part 211 and the second part 212.

[0055] In this embodiment, the linkage assembly 213 is disposed on the lower side of the main body 21. One end of the linkage assembly 213 is hinged to the first part 211, and the other end is hinged to the second part 212. The first part 211 and the second part 212 are connected by the linkage assembly 213 instead of a traditional hinge structure, so that the first part 211 and the second part 212 can be flipped relative to each other. The reason is that the axis of a traditional hinge must be located on the right-angled side below the first part 211 and the second part 212. When the first part 211 and the second part 212 are flush, half of the traditional hinge structure will protrude beyond the bottom surface of the first part 211 and the second part 212. This protruding structure will cause additional fluid resistance and is also at risk of being damaged by impact from the bottom of the water or foreign objects in the hand. In comparison, the connecting rod assembly 213 can position the hinged ends at a position higher than the bottom surface of the first part 211 and the bottom surface of the second part 212. When the first part 211 and the second part 212 are flush, the connecting rod assembly 213 is accommodated within the thickness of the first part 211 and the second part 212. When the first part 211 and the second part 212 are flipped and folded along the thickness direction, the conventional hinge will cause the bottom surfaces of the first part 211 and the second part 212 to be in close contact with each other. However, the connecting rod assembly 213 can separate the bottom surfaces of the first part 211 and the second part 212 by the length of the connecting rod assembly 213 itself, which makes it easier to design an outwardly protruding spray pump structure below the bottom surface of the second part 212, further pressing down the water inlet of the spray pump and reducing the proportion of air mixed in the water inlet when the water vehicle is in use.

[0056] Furthermore, the linkage assembly 213 includes a first linkage 2131 and a second linkage 2132. The motion planes of the first linkage 2131 and the second linkage 2132 are parallel to the side of the main body 21, and the motion planes of the first linkage 2131 and the second linkage 2132 do not coincide. The axes of the hinged portions at both ends of the first linkage 2131 and the hinged portions at both ends of the second linkage 2132 do not coincide.

[0057] In this embodiment, the forward and backward direction is defined by the direction of travel of the water vehicle. The first part 211 is located in front of the second part 212, and the second part 212 is located behind the first part 211. When the first part 211 and the second part 212 are aligned, the first connecting rod 2131 and the second connecting rod 2132 are located below the main body 21. The first connecting rod 2131 and the second connecting rod 2132 are plate-shaped structures. The first connecting rod 2131 and the second connecting rod 2132 are offset along the forward and backward direction and are arranged parallel to the side of the main body 21. The first connecting rod 2131 is biased towards the outside of the main body 21 relative to the second connecting rod 2132. The first part 211 and the second part 212 are provided with hinge seats that are hinged to the hinged parts at both ends of the first connecting rod 2131 and the second connecting rod 2132. The reason why a double-link structure is used instead of a single-link structure as the link assembly 213 in this application is that the single-link structure has too much freedom and poor stability of the flipping path. When the second part 212 flips relative to the first part 211, the two ends of the single-link structure are hinged to the first part 211 and the second part 212, so the single-link structure itself will also rotate relative to the first part 211 and the second part 212. As a result, the flipping path of the second part 212 relative to the first part 211 is not fixed, and multiple flipping adjustments are required to flip the second part 212 relative to the first part 211 into place. In the double-link structure, when the second part 212 flips relative to the first part 211, the first link 2131 and the second link 2132 are misaligned and set in parallel. The first link 2131 and the second link 2132 will form a reverse balance constraint force during the flipping process (of the second part 212 relative to the first part 211), ensuring that the flipping process is precise and controllable. After the flipping, the first part 211 and the second part 212 are in relative positions.

[0058] Furthermore, a locking assembly 3 is provided on the main body 21 to limit the unfolded state of the first part 211 and the second part 212 when they are flush; the locking assembly 3 includes a base 31, a handle 32, a latch 33 and a locking member 34. The base 31 is disposed on the second part 212 and is hinged to the handle 32. One end of the latch 33 is hinged to the handle 32, and the other end of the latch 33 is used to engage with the locking member 34 on the first part 211.

[0059] In this embodiment, the first part 211 and the second part 212 are flipped to be flush with the pivot point of the linkage assembly 213. However, since the linkage assembly 213 cannot limit the position of the first part 211 and the second part 212 after they are flipped to be flush, the first part 211 and the second part 212 cannot maintain their relative position in a flush state. Therefore, this application uses the locking assembly 3 to lock and fasten the first part 211 and the second part 212 when they are flush, limiting their relative flipping, so that the first part 211 and the second part 212 are in a stable flush state, so that the operator can carry out water activities on the vehicle. Furthermore, the first part 211 and the second part 212 are provided with receiving grooves. When the first part 211 and the second part 212 are flipped to be flush, the receiving grooves of the first part 211 and the second part 212 are arranged opposite to each other and cooperate with each other so that the locking assembly 3 is located in the receiving groove when the main body 21 is unfolded. When the main body 21 is unfolded, the setting of the receiving groove makes the locking assembly 3 and the surface of the main body 21 form the same plane, eliminating the interference of the protrusion of the exposed parts. From the perspective of spatial layout, the functional parts do not affect the use space, retaining the locking function of the locking assembly 3 without compromising the ease of use and folding safety of the main body 21. In addition, the state of the groove opening can help determine the locking status. By observing the position of the handle 32 and the buckle 33 in the groove, the user can intuitively confirm the locking status of the locking assembly, further enhancing the advantage of visual feedback. The locking fastener 34 is disposed on the first part 211. When the latch 33 is sleeved on the locking fastener 34, the locking fastener 34 will restrict the latch 33 from moving backward and flipping. Since one end of the latch 33 is hinged to the handle 32, and the handle 32 is disposed on the second part 212 through the base 31, the second part 212 is indirectly limited to flipping relative to the first part 211, thus realizing the locking state of the first part 211 and the second part 212.

[0060] Specifically, the base component 31 is fixedly disposed in the receiving groove of the second part 212 by screwing. The two sides of the open end of the handle component 32 are hinged to the two sides of the open end of the base component 31. The middle of the two sides of the handle component 32 is hinged to one end of the fastener 33 by a pin. When the handle component 32 rotates on the base component 31, it can synchronously drive the fastener 33 to move. The other end of the fastener 33 is used to fasten with the locking component 34 on the first part 211. The handle component 32 drives the fastener 33 to move, so as to adjust the cooperation relationship between the fastener 33 and the locking component 34. The locking component 34 is disposed in the receiving groove of the first part 211. The locking component 34 can be integrally formed with the first part 211 or the locking component 34 can be fixed in the receiving groove of the first part 211 by screwing. In this embodiment, the locking component 34 includes at least a locking part 341. The locking part 341 is a sheet structure. The main body 21 is inclined forward and disposed in the receiving groove of the first part 211. The other end of the fastener 33 is sleeved on the locking part 341. The locking part 341 forms a mechanical constraint on the fastener 33, so that the first part 211 and the second part 212 can be locked in a flush state by the locking assembly 3. When the fastener 33 is sleeved on the inclined locking part 341, the plane of the fastener 33 will form a non-perpendicular contact relationship with the inclined surface of the locking part 341. When the fastener 33 is subjected to external force and attempts to detach backward (such as the first part 211 and the second part 212 being accidentally pulled, causing the fastener 33 to have a tendency to loosen backward), the rear end of the inclined locking part 341 will form a stop structure. The sleeved end of the fastener 33 will be firmly locked by the inclined limiting surface of the locking part 341. The greater the external force, the stronger the locking effect, thereby preventing the fastener 33 from accidentally detaching when not in operation and ensuring the reliability of the locked state. Furthermore, because the locking part 341 is tilted forward, its front end (the end furthest from the bottom of the receiving groove of the first part 211) will be closer to the movement path of the fastener 33. When the handle 32 moves the fastener 33 closer to the locking part 341, the fastener 33 does not need to be completely aligned with the top of the locking part 341. It only needs to contact the inclined guide surface of the locking part 341, and under the guidance of the inclined surface, it can automatically slide into the fitting position, greatly improving the assembly tolerance. Further, when the side plate 22 of the first part 211 is flipped to the side of the first part 211 and the side plate 22 of the second part 212 is flipped to the side of the second part 212, a gap space is defined between the side plate 22 of the first part 211 and the side plate 22 of the second part 212 to accommodate the deflated inflation module 23.

[0061] In the embodiments of this application, to avoid relative interference between the side decks 22 of the first part 211 and the side decks 22 of the second part 212 when the first part 211 and the second part 212 are flipped relative to each other, the side decks 22 of the first part 211 extend at a certain angle on the side close to the first part 211 to form a spacer 2111. The spacer 2111 is fixedly connected to the flipping member 13 of the flipping mechanism. When the side decks 22 of the first part 211 are unfolded, the spacer 2111 is in contact with or approximately in contact with the side of the first part 211. When the side decks 22 of the first part 211 are flipped to the side of the first part 211, the spacer 2111 is in contact with or approximately in contact with the side of the first part 211. When the side is folded, it defines a gap space between the side deck 22 of the first part 211 and the side of the first part 211 in the horizontal direction, so as to accommodate the side deck 22 of the second part 212 after folding. By setting the gap 2111, the distance between the side deck 22 of the first part 211 and the side of the first part 211 after folding is increased. The side deck 22 of the second part 212 is staggered between the side deck 22 of the first part 211 and the side of the first part 211, which makes the structure of the folded water vehicle more compact and greatly reduces the space occupation rate of the water vehicle after folding and storage. Furthermore, based on the thickness direction of the main body 21, by setting intervals 2111 of different sizes (heights), the gap width between the side deck 22 of the first part 211 and the side of the first part 211 when the first part 211 is folded from a position flush with the main body 21 to the side position of the first part 211 can be adjusted (that is, the size of the gap space can be controlled); when the first part 211 and the second part 212 are flipped to be flush with each other, the inflation module 23 is located below the side deck 22 of the first part 211 and the side deck 22 of the second part 212, and the inflation module 23 is detachably connected to the side deck 22 of the second part 212. When the inflation module 23 is deflated, it can also be folded and placed in the gap space to achieve effective utilization of the gap space.

[0062] In this application, the watercraft also includes a folding mechanism 4 (i.e., a control lever) disposed on the main body 21 to provide the operator with stable grip support during the use of the watercraft; specifically, the folding mechanism 4 includes: a grip component 41, on which a first connecting part 4112 is provided; a support member 42, on which the grip component 41 is mounted, and on which a second connecting part 422 is provided that cooperates with the first connecting part 4112 to limit the installation angle of the grip component 41 on the support member 42; and a locking component, which is used to lock the grip component 41 on the support member 42, and by rotating the locking component, the installation angle of the grip component 41 on the support member 42 is locked, or the locked state of the installation angle is released; When the locking assembly rotates in the first direction, it presses against the support member 42, causing the support member 42 to abut against the gripping assembly 41, thereby locking the engagement relationship between the first connecting part 4112 and the second connecting part 422. When the locking assembly rotates in the second direction, the support member 42 and the gripping assembly 41 are released from their abutment relationship, and the first connecting part 4112 and the second connecting part 422 can move relative to each other.

[0063] In existing technologies, the control levers of most watercraft are fixed, rigidly connected to the watercraft body through welding, bolting, or other methods, making them impossible to fold. During transportation, the control levers are highly susceptible to collisions with other objects, causing damage to the control levers or the watercraft body. When storing the watercraft, fixed control levers also make it difficult to neatly arrange the watercraft in limited spaces such as warehouses or home storage rooms, resulting in wasted space. In the folding mechanism of the watercraft in this application, the first connecting part 4112 on the grip component 41 cooperates with the second connecting part 422 on the support member 42 to limit the installation angle of the grip component 41 on the support member 42. By rotating the locking component, the relative relationship between the support member 42 and the grip component 41 is changed to lock or engage the locked state of the installation angle, enabling the grip component 41 to fold. This solves the problems of large space occupation and easy collision during transportation and storage of traditional fixed control levers, significantly reducing the space occupied when not in use and improving portability.

[0064] In one embodiment of this application, the locking assembly includes a pivot member 431, a fastener 433, and a locking member 432. One end of the pivot member 431 passes through the support member 42 and the gripping assembly 41 and is fixedly connected to the fastener 433. The other end of the pivot member 431 is hinged to the cam portion 4321 of the locking member 432. The cam portion 4321 includes a first abutment surface 4322 and a second abutment surface 4323. The distance from the first abutment surface 4322 to the rotation axis of the cam portion 4321 is greater than the distance from the second abutment surface 4323 to the rotation axis of the cam portion 4321. When the locking member 432 rotates in a first direction, the cam portion 4321... The first abutment surface 4322 presses against the support member 42, causing the support member 42 to abut against the gripping component 41, thereby locking the engagement relationship between the first joint 4112 and the second joint 422; when the locking member 432 rotates in a second direction opposite to the first direction, there is no relative compression between the second abutment surface 4323 and the support member 42, the support member 42 and the gripping component 41 are released from the abutment relationship, and the first joint 4112 and the second joint 422 can move relative to each other; by rotating the locking member 432, the installation angle of the gripping component 41 on the support member 42 is locked, or the locked state of the installation angle is released.

[0065] Specifically, fastener 433 and locking member 432 are located on opposite sides of support member 42. Pivot member 431 includes pivot portion 4313 and limiting portion 4314, which are located at both ends of pivot member 431. Pivot portion 4313 is hinged to cam portion 4321 of locking member 432. Limiting portion 4314 passes through support member 42 and grip assembly 41 from the side where locking member 432 is located and is fixedly connected to fastener 433 to limit pivot member 431 to support member 42. Locking member 432 includes cam portion 4321 and grip portion 4324 extending along the periphery of cam portion 4321. Cam portion 4321 is hinged to pivot portion 4313 by pin. Grip portion 4324 allows user to rotate locking member 432 in a first direction or a second direction.

[0066] When the user rotates the locking member 432 in the first direction, the cam portion 4321 rotates synchronously and exerts pressure on one side of the support member 42 through the first abutment surface 4322 of the cam portion 4321. The other side of the support member 42 will exert pressure on the fastener 433. In this case, the support member 42 will abut against the gripping component 41, and the engagement relationship between the first coupling portion 4112 and the second coupling portion 422 will be locked, thereby locking the installation angle of the gripping component 41 on the support member 42. When the user rotates in the second direction (i.e., the opposite direction to the first direction), the user will rotate in the second direction (i.e., the opposite direction to the first direction). When the locking member 432 is rotated, the cam portion 4321 rotates synchronously, and the first abutment surface 4322 of the cam portion 4321 disengages from the support member 42. The pressing force of the cam portion 4321 on the support member 42 disappears in the direction of the pivot member 431. In this situation, the support member 42 and the gripping assembly 41 are released from their abutment relationship, and the first connecting portion 4112 and the second connecting portion 422 can move relative to each other. At this time, the user can adjust the mounting angle of the gripping assembly 41 on the support member 42 (that is, rotate the gripping assembly 41 along the axis of the pivot member 431). Furthermore, in this embodiment, the first direction refers to the direction in which the locking member 432 rotates towards the side closer to the gripping assembly, and the second direction refers to the direction of rotation opposite to the first direction. Figure 12 As shown, the arc surface corresponding to F of the cam portion 4321 is the first abutment surface 4322, and the arc surface corresponding to G of the cam portion 4321 is the second abutment surface 4323. Of course, alternatively, the relative positions of the first abutment surface 4322 and the second abutment surface 4323 on the cam portion 4321 can be changed to alter the relative rotation direction of the aforementioned locking member.

[0067] Furthermore, the fastener 433 is a nut, and the outer periphery of the limiting part 4314 is threaded. The limiting part 4314 passes through the support member 42 and the gripping assembly 41 from the locking member 432 side and is screwed and fixed to the nut to ensure the stability of the pivot member 431 installation. The nut, through the threaded connection, cooperates with the pivot member 431 to provide a continuous and adjustable preload, tightly pressing the support member 42 and the gripping assembly 41 together, effectively eliminating the gap between the two supports. The nut can provide additional preload, which makes the pivot member 431 more stably installed on the support member 42, enhancing the stability of the entire folding mechanism 4, reducing the deformation of the folding mechanism 4 under stress, reducing the additional stress caused by structural shaking, and preventing premature fatigue damage of components. When adjusting the installation angle of the gripping assembly 41 on the support member 42, the basic preload can also be adjusted by appropriately loosening the nut to avoid adjustment jamming due to excessive tightness or inaccurate angle positioning due to excessive looseness, thus ensuring the reliability of parallel locking and the flexibility of adjustment. Furthermore, when it is necessary to repair or replace the grip assembly 41, support 42 or pivot 431, the pivot 431 can be easily removed from the support 42 and grip assembly 41 by simply unscrewing the nut, thus facilitating the separation of the various components.

[0068] Furthermore, an abutment 44 is provided on one side of the support member 42, and the abutment 44 is provided with a contact surface 441 for adapting to the cam portion 4321.

[0069] A contact member 44 is provided on one side of the support member 42 to contact the cam portion 4321. A through hole is provided in the middle of the contact member 44. One end of the pivot member 431 passes through the contact member 44, then through the support member 42 and the gripping assembly 41, and is screwed to the fastener 433. The surface of the contact member 44 forms a contact surface 441 for the cam portion 4321 to abut. The first contact surface 4322 of the cam portion 4321 transmits force by contacting the contact surface 441. Compared to directly setting the contact surface 441 on the support member 42, indirectly transmitting the pressing force of the cam portion 4321 to the support member 42 or the gripping component 41 through the abutment member 44 has the following advantages: the abutment member 44 can be processed as an independent component, and the flatness, curvature, and other precision requirements of its contact surface 441 are easier to achieve, which can more accurately adapt to the abutment requirements of the cam portion 4321 on the locking member 432, improving the stability of locking and unlocking; the abutment member 44 needs to be in frequent contact with the cam portion 4321 (enduring compression and friction), so wear-resistant and high-strength materials can be selected separately. The material can be either rigid or has appropriate elasticity, while the support component 42 can be made of other materials according to structural strength, lightweight requirements, etc., so as to reduce the overall cost while ensuring contact reliability. If the contact surface 441 is worn or deformed due to long-term use, only the independent abutment component 44 needs to be replaced, without replacing the entire support component 42, thus reducing maintenance costs. The cam part 4321 presses the support component 42 through the abutment component 44, which increases the pressing area, making the transmission of pressing force more uniform and stable, and improving the stability of the angle of the grip component 41 when in use (standing and operating the water vehicle).

[0070] Preferably, the contact surface 441 is an arc-shaped surface. The arc-shaped surface reduces the frictional resistance when the cam part 4321 rotates, making the locking and unlocking operations smoother and less strenuous; compared with planar contact, the arc-shaped surface can disperse contact stress, reduce local wear, and extend the service life of the component; the arc-shaped surface has a higher fit with the cam part 4321, increasing the contact area between the first and second abutment surfaces 4323 and the contact surface 441, and improving locking stability.

[0071] Furthermore, the support member 42 includes a support body 421 connected to the water vehicle, with both ends of the support body 421 bent toward the gripping assembly 41 to form two opposing second joint portions 422; the support body 421 and the second joint portions 422 define an accommodating space for one end of the gripping assembly 41 to extend into, and the locking assembly presses the first joint portion 4112 through the second joint portion 422 to lock the mounting angle of the gripping assembly 41 on the support member 42.

[0072] Specifically, the first connecting portion 4112 is a sheet-like structure extending from the lower end of the gripping component 41, and at least two of them are provided, with the two first connecting portions 4112 being arranged opposite each other. The second connecting portion 422 is two sheet-like structures formed by bending the two ends of the supporting body 421 respectively. When the gripping component 41 is mounted on the support member 42, the first connecting portion 4112 and the second connecting portion 422 on the same side are arranged opposite each other. In this embodiment, the first connecting portion 4112 and the second connecting portion 422 are planar sheet-like structures, and the supporting body 421 and the two oppositely arranged second connecting portions 422 form a U-shaped structure. The lower end of the gripping component 41... When the locking member 432 is inserted into the U-shaped structure, the second connecting part 422 is located outside the first connecting part 4112. When the locking member 432 rotates in the first direction, the first abutting surface 4322 of the cam part 4321 presses against the second connecting part 422 on the side close to the locking member 432, and the fastener 433 abuts against the second connecting part 422 on the other side, so as to cause the second connecting part 422 to be pressed against the first connecting part 4112 to form an abutment. The first connecting part 4112 and the second connecting part 422 are in planar contact. At this time, the cooperation relationship between the two is fixed under the action of the relative friction between the first connecting part 4112 and the second connecting part 422. The symmetrical design of the double-sided compression ensures that the grip component 41 is subjected to uniform force, avoiding tilting or loosening caused by unilateral compression and improving the structural stability of the grip component 41 during use; the U-shaped structure forms a wrap-around limit on the grip component 41, reducing lateral swaying during use and enhancing operational safety; the integrated structure of the support body 421 and the second joint 422 has high strength, further improving the stability of the contact between the grip component 41 and the support member 42.

[0073] Furthermore, the first connecting portion 4112 is provided with a first limiting portion 4113, and the second connecting portion 422 is provided with a second limiting portion 424 that cooperates with the first limiting portion 4113, so as to limit the installation angle of the gripping component 41 on the support member 42 when the first connecting portion 4112 and the second connecting portion 422 cooperate.

[0074] The second connecting portion 422 is located outside the first connecting portion 4112. The first limiting portion 4113 is a protrusion provided on the outer wall of the first connecting portion 4112, and the second limiting portion 424 is a snap-fit ​​hole provided on the second connecting portion 422. The hard limiting structure formed by the cooperation of the protrusion and the snap-fit ​​hole can limit the installation angle of the gripping component 41 on the support member 42. In this embodiment, there is one first limiting portion 4113 and two second limiting portions 424. One protrusion matches two snap-fit ​​holes to lock the position of the gripping component 41 when it is in the supporting and retracted positions. It should be noted that the installation angle of the gripping component 41 on the support member 42 can be determined by the position of the first limiting portion 4113 on the first connecting portion 4112 and the position of the second limiting portion 424 on the second connecting portion 422. In addition, multiple snap-fit ​​holes can be preset to match a single protrusion, providing discrete and clear positioning positions for the installation angle of the grip component 41 (such as a position where a protrusion and snap-fit ​​hole are matched for every 15° or 30° rotation), so that the installation angle of the grip component 41 can be adapted to different users (such as operators of different heights) and their operating habits (such as operating the water vehicle while standing or sitting).

[0075] When a watercraft is subjected to dynamic loads such as water flow impact and engine vibration, without the abutting pressure of the first joint 4112 and the second joint 422, the protrusion and the locking hole are prone to relative wobbling due to the gap. Over time, this may lead to wear of the protrusion and deformation of the locking hole (especially in a saltwater corrosive environment), eventually resulting in the loss of the limiting function. The locking constraint formed by the abutting pressure can ensure that the protrusion is always tightly fitted with the hole wall of the locking hole, eliminating the fit gap between the two. The lateral support of the hole wall on the protrusion resists the shear force generated by vibration, thus preventing the limiting structure from loosening at the source and solving the problem of limiting failure under dynamic loads. The engagement between the protrusion and the snap-fit ​​hole is a form lock, while the abutment of the first and second joints 422 is a force lock, forming a double constraint. The form lock (the protrusion snaps into the snap-fit ​​hole) directly restricts the relative rotation of the two through the mechanical structure, which is the core guarantee for limiting the installation angle of the grip component 41 on the support member 42. The force lock strengthens the stability of the form lock through friction and pressure, preventing the form lock from failing due to local wear (such as the protrusion becoming round). This double-safety design can significantly improve the fault tolerance of the structure compared to a single form lock or force lock.

[0076] Furthermore, the pivot member 431 is provided with a flat portion 4315, and the gripping assembly 41 is provided with an installation channel 414 for one end of the pivot member 431 to pass through. The installation channel 414 is provided with a flat segment 4141 to fit the flat portion 4315.

[0077] In this application, the mounting channel 414 has a flat section 4141 at one end near the locking member 432. When the pivot member 431 passes through the mounting channel 414, the flat section 4315 tightly engages with the flat end within the mounting channel 414, rigidly restricting the circumferential rotation of the pivot member 431 within the mounting channel 414 (i.e., restricting the relative rotation between the pivot member 431 and the gripping assembly 41). This avoids relative wear between the pivot member 431 and the gripping assembly 41 after long-term use, preventing the gripping assembly 41 from becoming loose. It also avoids... When the gripping component 41 rotates, the pivot 431 slips in the mounting channel 414, affecting the rotation effect of the gripping component 41; the flat fit also prevents the pivot 431 from sliding axially in the mounting channel 414, ensuring that when the locking part 432 rotates, the squeezing force of the cam part 4321 can be accurately transmitted to the support part 42 or the gripping component 41, preventing the loss or displacement of the squeezing force; the flat part 4315 and the flat part shape match the directional assembly characteristics, which can quickly achieve the axial positioning of the pivot 431 and the gripping component 41 during the installation process.

[0078] Furthermore, the gripping assembly 41 includes a rotating member 411, a gripping member 412, and a clamping structure 413. One end of the rotating member 411 is pivotally connected to the support member 42, and the other end of the rotating member 411 is provided with an opening. The mounting end of the gripping member 412 extends into the cavity of the rotating member 411 through the opening. The length of the gripping member 412 within the cavity of the rotating member 411 can be adjusted along the direction of the opening. The clamping structure 413 is used to fix the relative position of the gripping member 412 on the rotating member 411.

[0079] In this embodiment, the rotating component 411 is a hollow cavity. The lower end of the rotating component 411 is pivotally connected to the support component 42, and the upper end of the rotating component 411 is provided with an opening. The gripping component 412 extends into the rotating component 411 through the upper opening of the rotating component 411. The clamp structure 413 can fix the relative position of the gripping component 412 on the rotating component 411. The clamp assembly fixes the adjusted length of the gripping component 412, so that the gripping component 41 can adapt to the gripping habits of users of different heights (such as children and adults, standing and sitting postures), improving the comfort and practicality of use. The clamp structure 413 has a simple and reliable fixing method, and there is no loosening after adjustment, ensuring the stability of the gripping component 41 during operation. While the gripping component 41 is telescopically adjustable, it can also be folded and rotated around the pivot component 431 as an axis, enhancing the portability of the water vehicle and making it easy to store the water vehicle during transportation or when not in use.

[0080] Furthermore, the rotating member 411 extends outward from one end of the opening to form a pipe opening 4111, and the clamping structure 413 is sleeved on the outer periphery of the pipe opening 4111, with the lower end of the clamping structure 413 contacting the upper end face of the rotating member 411; a sleeve member 45 is also provided between the pipe opening 4111 and the gripping member 412, and the end of the sleeve member 45 extends outward to form a support portion 451 to support the sleeve member 45 on the pipe opening 4111.

[0081] In this application, the upper opening of the rotating member 411 extends outward to form a nozzle 4111. The rod of the gripping member 412 enters the hollow cavity of the rotating member 411 through the nozzle 4111. The clamping structure 413 includes a base 4131 and an adjusting part 4132 connected to the base 4131. The base 4131 is circular or elliptical. Preferably, in this embodiment, the base 4131 is elliptical, and the radial cross-sectional shape of the rod of the gripping member 412 is the same as the radial cross-sectional shape of the nozzle 4111. The base 4131 and the adjusting part 4132 are connected together. The shape of the section 4132 is adapted to the radial cross section of the nozzle 4111. The adjusting section 4132 is provided with a notch. The end face of the notch extends along the major axis of the elliptical ring to form two oppositely arranged connecting ears. The two connecting ears are tightened circumferentially by bolts and nuts (which is a common clamp locking method, which is the prior art) or by using a locking assembly similar to that in this application to drive the deformation of the adjusting section 4132. The base 4131 and the adjusting section 4132 are connected by an arc surface to avoid the deformation of the adjusting section 4132 from affecting the structure of the base 4131. The lower end of the base 4131 contacts the end face of the rotating part 411. On the one hand, it provides a horizontal reference for the clamp structure 413, ensuring that the central axis 14 of the clamp structure 413 is coaxial with the axis of the pipe opening 4111 and the gripper 412. This avoids uneven distribution of the squeezing force on the pipe opening 4111 due to installation deviation, which affects the reliability of the clamp structure 413 locking. On the other hand, it can accurately limit the lowest position of the clamp structure 413 in the axial direction, ensuring that the squeezing action of the clamp structure 413 is concentrated in the effective mating section between the pipe opening 4111 and the sleeve 45 (i.e., the key area where the pipe opening 4111 needs to be tightened to clamp the gripper 412). If the axial position of the clamp structure 413 cannot be calibrated, it may exceed the effective length range of the pipe opening 4111, resulting in the inability to effectively clamp the gripper 412. Meanwhile, this axial reference ensures the consistency of the axial position of the clamp structure 413 during each installation or adjustment, allowing the operator to determine that the clamp structure 413 is in an effective working position simply by feeling the lower end of the clamp structure 413 against the upper end surface of the rotating part 411, without the need for additional positioning marks, thus improving the ease of operation.

[0082] Furthermore, the radial cross-section of the rod portion and the nozzle portion 4111 of the gripper 412 is set to be elliptical rather than circular, which avoids the gripper 412 rotating axially on the rotating part 411 when it is assembled on the rotating part 411, which is conducive to the quick installation and adjustment of the gripper 412 on the rotating part 411; the connecting ear of the adjustment part 4132 is set on one side of the long axis end of the elliptical ring, which can increase the adjustment lever arm and make the locking operation of the adjustment part 4132 easier.

[0083] In this embodiment, a plastic sleeve 45 is further provided between the nozzle 4111 and the gripper 412. The upper end of the sleeve 45 extends outward to form an annular flange (i.e., a support 451), and the lower end of the sleeve 45 extends into the nozzle 4111. The support 451 is placed on the end face of the nozzle 4111, stably supporting the sleeve 45 on the nozzle 4111. The inner diameter of the sleeve 45 is adapted to the outer diameter of the gripper 412, and the outer diameter of the sleeve 45 is adapted to the inner diameter of the nozzle 4111. In this application, the rod of the gripper 412 is made of carbon fiber, while the rotating part 411 and the nozzle 4111 are made of metal. The sleeve 45 prevents direct contact between the nozzle 4111 and the rod of the gripper 412, reducing wear between them. At the same time, the sleeve 45 indirectly increases the relative friction between the nozzle 4111 and the rod of the gripper 412, improving the locking effect of the clamp structure 413 on the nozzle 4111 and the gripper 412. The support part 451 ensures that the sleeve 45 will not slide axially during use, ensuring assembly accuracy. In addition, the versatility of the components can be improved by replacing the sleeve 45 with different thicknesses to adapt to grippers 412 of different sizes.

[0084] In summary, this utility model provides a watercraft and its overturning mechanism. The overturning mechanism of the watercraft includes: a fixed base, which is fixedly connected to the main body of the watercraft; an adjusting rod, which is disposed on the fixed base and can be axially adjusted along its own setting direction; and an overturning component, which is connected to the side deck of the watercraft and is disposed on the fixed base via a spindle, the spindle being parallel to the adjusting rod. The adjusting rod is adjusted axially, and the overturning component drives the side deck to rotate around the spindle, so as to unfold the side deck to be flush with the main body or fold the side deck to the side of the main body.

[0085] The tilting mechanism of this application for a watercraft allows for axial adjustment of an adjusting rod along its designated direction. This causes the tilting component to rotate around a central axis while simultaneously tilting the side deck against the side of the main body, thereby unfolding the side deck to be flush with the main body or folding it to the side of the main body. In this application, the axial position of the adjusting rod is controlled to limit or release the tilting component, enabling rapid tilting and adjustment of the side deck. The structure is simple and the operation is convenient.

[0086] It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of this utility model, and all such substitutions or modifications should fall within the protection scope of the appended claims.
