[0028] See also Figure 1 The surfing device 100 includes a surfboard body (not shown), a mast 10, a driving assembly 20, a propeller 30 and a connecting rod mechanism 40. The first end of the mast 10 is fixedly connected to the bottom of the surfboard body. The driving assembly 20 is fixedly connected to the second end of the mast 10.

[0029] See also Figure 1 , Figure 2 and Figure 3The propeller 30 includes the hub 31 and the blade assembly 32, and the hub 31 is fixedly connected to the output shaft of the driving assembly 20. The blade assembly 32 includes the first blade 321 and the second blade 322, and the hub 31 is provided with the receiving groove 311. The first blade 321 and the second blade 322 are rotatably connected to the hub 31, and the first blade 321 and the second blade 322 are arranged on opposite sides of the hub 31. The connecting rod mechanism 40 is accommodated in the receiving groove 311, and the connecting rod mechanism 40 includes a first connecting arm 41, a second connecting arm 42 and the first mounting member 43. The first connecting arm 41 is fixed to the first blade 321, and the second connecting arm 42 is fixed to the second blade 322. The first connecting arm 41 and the second connecting arm 42 are slidably connected through the first mounting member 43 to drive the first blade 321 and the second blade 322 to move in linkage. By setting the connecting rod mechanism 40, the first blade 321 and the second blade 322 can be synchronously unfolded and folded, so that the water resistance can be reduced by folding the blade assembly 32 when there are waves, and power can be provided by unfolding the blade assembly 32 when there are no waves.

[0030] In the embodiment of the present application, the mast 10 is a long strip structure, and its cross section is designed to be teardrop-shaped to reduce its resistance in water. The mast 10 adopts a hollow structure, which is convenient for arranging the power cable and the signal cable inside.

[0031] For details, please refer to Figure 3 The first connecting arm 41 is provided with the first sliding groove 401, the second connecting arm 42 is provided with the second sliding groove 402, the first mounting member 43 is sequentially inserted into the first sliding groove 401 and the second sliding groove 402, and the first mounting member 43 can slide along the first sliding groove 401 and the second sliding groove 402.

[0032] The first mounting member 43 slides in the first sliding groove 401 and the second sliding groove 402, which can drive the first connecting arm 41 and the second connecting arm 42 to move, thereby realizing the synchronous rotation of the first paddle blade 321 and the second paddle blade 322. When there are waves, the first paddle blade 321 and the second paddle blade 322 can be automatically retracted to reduce the water resistance of the surfing device 100, so that the surfer can have a better gliding experience; when there are no waves, the first paddle blade 321 and the second paddle blade 322 can be automatically unfolded under the action of centrifugal force to provide power for the surfing device 100. This automatic adjustment feature enables the surfing device 100 to adapt to different water conditions and enhance the surfing experience.

[0033] For further information, see Figure 4The connecting rod mechanism 40 further includes a third connecting arm 44, a fourth connecting arm 45, and a second mounting member 46. The first connecting arm 41 is fixed to the first blade 321, the second connecting arm 42 is fixed to the second blade 322, and the first connecting arm 41 and the second connecting arm 42 are slidably connected through the first mounting member 43 to drive the first blade 321 and the second blade 322 to move in a coordinated manner. The third connecting arm 44 is fixed to the first blade 321, the fourth connecting arm 45 is fixed to the second blade 322, and the third connecting arm 44 and the fourth connecting arm 45 are slidably connected through the second mounting member 46 to drive the first blade 321 and the second blade 322 to move in a coordinated manner. The first connecting arm 41 and the third connecting arm 44 are arranged opposite to each other, and the second connecting arm 42 and the fourth connecting arm 45 are arranged opposite to each other.

[0034] The first connecting arm 41 is provided with the first sliding groove 401, the second connecting arm 42 is provided with the second sliding groove 402, the first mounting member 43 is sequentially inserted into the first sliding groove 401 and the second sliding groove 402, and the first mounting member 43 can slide along the first sliding groove 401 and the second sliding groove 402. The third connecting arm 44 is provided with the third sliding groove 404, the fourth connecting arm 45 is provided with the fourth sliding groove 405, the second mounting member 46 is sequentially inserted into the third sliding groove 404 and the fourth sliding groove 405, and the second mounting member 46 can slide along the third sliding groove 404 and the fourth sliding groove 405.

[0035] By providing the first mounting member 43, the second mounting member 46 and their corresponding sliding grooves, a double linkage mechanism is formed. The sliding of the first mounting member 43 in the first sliding groove 401 and the second sliding groove 402, and the sliding of the second mounting member 46 in the third sliding groove 404 and the fourth sliding groove 405, work together to drive the first blade 321 and the second blade 322 to move. This double linkage structure improves the stability and reliability of the movement of the blade assembly 32, making the deployment and folding actions of the first blade 321 and the second blade 322 smoother and more synchronous, thereby improving the adaptability and use experience of the surfing device 100 in different water conditions.

[0036] In the embodiment of the present application, the structures of the first blade 321 and the second blade 322 are completely identical, and are centrally symmetrically distributed after installation. The rotation of the first connecting arm 41 and the second connecting arm 42 can synchronously drive the first mounting member 43 to slide in the first sliding groove 401 and the second sliding groove 402 in the runway shape, thereby realizing the synchronous folding and unfolding function of the blades. This structural design enables the propeller 30 to automatically adjust its state according to actual use requirements, thereby improving the adaptability and use experience of the surfing device 100.

[0037] Please refer to 5 , the surfing device 100 further includes a limiting mechanism 50 , and the limiting mechanism 50 includes the first limiting member 51 and the second limiting member (not shown).

[0038] The inner wall of the installation groove is provided with the first limiting groove 52 and the second limiting groove 53, and the second limiting groove 53 is arranged opposite to the first limiting groove 52. One end of the first limiting member 51 is slidably arranged in the first limiting groove 52, and one end of the first mounting member 43 passes through the first guide hole and the second guide hole and is connected to the other end of the first limiting member 51, so that the first mounting member 43 can slide upward or downward along the first limiting groove 52. One end of the second limiting member is slidably arranged in the second limiting groove 53, and one end of the second mounting member 46 is connected to the other end of the second limiting member, so that the second mounting member 46 can slide upward or downward along the second limiting groove 53.

[0039] The setting of the limiting mechanism 50 can effectively constrain the movement trajectory of the first mounting member 43 and the second mounting member 46. The setting of the first limiting groove 52 and the second limiting groove 53 allows the first limiting member 51 and the second limiting member to move only in the vertical direction, thereby ensuring that the first mounting member 43 and the second mounting member 46 drive the blade assembly 32 to expand and retract along a predetermined path. This limiting structure further improves the accuracy and reliability of the movement of the blade assembly 32, avoids the deviation or jamming of the first blade 321 and the second blade 322 during the movement, and makes the performance of the surfing device 100 more stable and reliable.

[0040] In the embodiment of the present application, the limiting mechanism 50 cooperates with the aforementioned double linkage structure to form a complete blade control system. When the water flow impacts the blade assembly, the first limiting member 51 and the second limiting member slide in their respective limiting grooves, driving the mounting member to move in the corresponding sliding groove, and finally achieving the synchronous retraction of the first blade 321 and the second blade 322; when the driving assembly 20 starts to work, under the action of centrifugal force, the entire mechanism moves in the opposite direction, so that the blade assembly 32 automatically unfolds and maintains a stable working state.

[0041] See also Figure 6 , the surfing device 100 further includes the first fixing member 60, the second fixing member (not shown), the first anti-collision block 70 and the second anti-collision block (not shown). The first blade 321 includes the first blade body 301 and the first mounting portion 302, the first blade body 301 and the first mounting portion 302 are connected, and the first connecting arm 41 and the third connecting arm 44 are arranged on the first mounting portion 302. The first connecting arm 41 is provided with the first fixing hole 47, the third connecting arm 44 is provided with the second fixing hole 48, and the hub 31 is provided with the first mounting hole 61 and the second mounting hole 62. The first fixing member 60 passes through the first mounting hole 61, the first fixing hole 62, and the second fixing hole 61 in sequence and is fixed to the second mounting hole 62, so that the first blade 321 is rotatably connected to the hub 31.

[0042] The second blade 322 includes the second blade body (not shown) and the second mounting portion (not shown), the second blade body is connected to the second mounting portion, and the second connecting arm 42 and the fourth connecting arm 45 are arranged on the second mounting portion. The second connecting arm 42 is provided with the third fixing hole (not shown), the fourth connecting arm 45 is provided with the fourth fixing hole (not shown), and the hub 31 is provided with the third mounting hole (not shown) and the fourth mounting hole (not shown). The second fixing member passes through the third mounting hole, the third fixing hole, and the fourth fixing hole in sequence, and is fixed to the fourth mounting hole, so that the second blade 322 is rotatably connected to the hub 31.

[0043] The side wall of the hub 31 is symmetrically provided with the first mounting groove 304 and the second mounting groove (not shown), the first anti-collision block 70 is provided in the first mounting groove 304, and the second anti-collision block is provided in the second mounting groove. One end of the first mounting portion 302 abuts against the first anti-collision block 70, and one end of the second mounting portion abuts against the second anti-collision block.

[0044] The first fixing member 60 and the second fixing member adopt a pin structure, one end of the pin is provided with the pin head, the other end is provided with the pin tail, the diameter of the pin head is larger than the diameter of the middle part of the pin, and the pin tail is provided with the thin-walled hole for riveting and fixing. The structural design of the pin head can prevent the fixing member from completely passing through the mounting hole.

[0045] This improved fixing structure design, through a fixing member penetrating two fixing holes on the connecting arm at the same time, enhances the stability and reliability of the connection between the blade assembly 32 and the hub 31. The symmetrical arrangement of the first fixing member 60 and the second fixing member ensures the balance of the movement of the blade assembly 32 and improves the operation effect of the entire mechanism.

[0046] The first anti-collision block 70 and the second anti-collision block are made of flexible materials, such as resin, plastic or silicone rubber. The upper and lower surfaces of the anti-collision block are parallel structures, and the shape matches the shape of the receiving groove 311 to ensure that they will not be easily loosened after installation.

[0047] In the embodiment of the present application, the upper and lower surfaces of the first anti-collision block 70 and the second anti-collision block are designed in parallel structure, and their outer shapes are not limited, but need to match the shape of the anti-collision block receiving groove 311 on the hub 31 to ensure that the anti-collision block will not be easily loosened after being placed in the groove. The material of the anti-collision block can be selected from various resins, plastics, silicone rubber and other relatively flexible materials.

[0048] The provision of the fixing member realizes a rotatable connection between the blade and the hub 31, so that the blade can be unfolded and retracted around the fixing member. The provision of the anti-collision block plays a buffering and protective role when the blade moves to the extreme position, avoiding a rigid collision between the blade and the hub 31, thereby extending the service life of the components.

[0049] The symmetrical arrangement of the first fixing member 60 and the second fixing member, and the symmetrical setting of the first anti-collision block 70 and the second anti-collision block, make the whole mechanism have good balance, and ensure the stability and reliability of the movement of the blade assembly 32. This structural design not only ensures the smoothness of the movement of the blade assembly 32, but also improves the service life and safety of the whole surfing device 100.

[0050] See also Figure 7 The driving assembly 20 includes a driving motor 201 , a front wing 202 and a rear wing 203 .

[0051] The housing of the driving motor 201 is fixedly connected to the second end of the mast 10, and the driving motor 201 includes the stator part and the rotor part. The stator part is fixed in the motor housing, and the rotor part is connected to the propeller 30. The rotation of the motor drives the propeller 30 to rotate, thereby pushing the surfing device 100 forward.

[0052] The front wing 202 is fixed to the housing of the driving motor 201. The overall shape of the front wing 202 is designed to be spread out like a wing, and Bernoulli's theorem is used to provide lift for the surfing device 100 when it moves forward. The provision of the front wing 202 can gradually lift the surfboard body during the moving process and leave the water surface, thereby effectively reducing the resistance of the surfing device 100 in the water.

[0053] The rear wing 203 is fixedly connected to the housing of the driving motor 201 through the connecting rod. The main function of the rear wing 203 is to provide a downward pulling force for the tail of the surfing device 100, and this force can help balance the entire surfing device 100 and keep it stable during travel.

[0054] This structural design of the driving component 20 organically combines the power system with the water power system. The driving motor 201 provides basic power, the front wing 202 provides lift through the principle of fluid dynamics, and the rear wing 203 provides stability. The three work together to enable the surfing device 100 to operate smoothly and efficiently on the water surface. When there are waves, the driving motor 201 is turned off, and the propeller 30 can be automatically retracted to reduce resistance; when there are no waves, the driving motor 201 is started, and the propeller 30 automatically unfolds under the action of centrifugal force to provide power for the surfing device 100. This intelligent driving method enables the surfing device 100 to adapt to different usage environments and provide users with a better surfing experience.

[0055] The embodiment of the present application provides a surfing device 100, including a surfboard body, a mast 10, a driving assembly 20, a propeller 30 and a connecting rod mechanism 40; the first end of the mast 10 is fixedly connected to the bottom of the surfboard body, the driving assembly 20 is fixedly connected to the second end of the mast 10, the propeller 30 includes a hub 31 and a blade assembly 32, the hub 31 is fixedly connected to the output shaft of the driving assembly 20, the blade assembly 32 includes a first blade 321 and a second blade 322, the hub 31 is provided with a receiving groove 311, the first blade 321 and the second blade 322 2 is rotatably connected to the hub 31, wherein the first blade 321 and the second blade 322 are arranged on opposite sides of the hub 31; the connecting rod mechanism 40 is received in the receiving groove 311, and the connecting rod mechanism 40 comprises a first connecting arm 41, a second connecting arm 42 and a first mounting member 43, the first connecting arm 41 is fixed to the first blade 321, the second connecting arm 42 is fixed to the second blade 322, and the first connecting arm 41 and the second connecting arm 42 are slidably connected through the first mounting member 43 to drive the first blade 321 and the second blade 322 to move in conjunction. By setting a connecting rod mechanism 40, when the first paddle 321 rotates, the second paddle 322 is driven to move synchronously through the connecting rod mechanism 40, so that the paddle assembly 32 can be automatically adjusted in different situations. When surfing in a wave area, the drive assembly 20 is turned off, and the impact of the water flow causes the paddle assembly 32 to automatically retract and reduce resistance, thereby reducing the resistance in the water, extending the gliding distance, and increasing the gliding speed; when the drive assembly 20 is required to drive, the paddle automatically unfolds under the action of centrifugal force to provide propulsion power. The above arrangement not only extends the battery life of the surfing device 100, but also improves the user's surfing experience, so that surfers can obtain good use results both in the wave and no wave state.

[0056] The present application also provides an electric surfboard, comprising the surfing device 100 as described in any one of claims 1 to 9. The electric surfboard can be used in both windy and waveless conditions, and can provide a good surfing experience for the user.

[0057] When there is no wind or waves, the electric surfboard completely relies on the thrust of the drive motor 201 and the propeller 30 to surf on the water surface. At this time, the blades of the propeller 30 are automatically unfolded under the action of centrifugal force, and driven by the drive motor 201, they rotate at high speed to provide forward power for the electric surfboard. The front wing 202 provides lift when the surfboard moves forward, so that the board rises out of the water to reduce resistance, while the rear wing 203 maintains overall balance during driving.

[0058] When surfing in a windy and wavey area, the user can glide with the help of the power of the waves. At this time, the drive motor 201 can be turned off, and the blades of the propeller 30 will automatically and synchronously retract under the impact of the water, significantly reducing the resistance of the underwater part of the electric surfboard in the water, so that the surfer can get a higher-speed surfing experience. When the waves disappear and you need to continue moving forward, you only need to restart the drive motor 201, and the blades of the propeller 30 will automatically unfold under the action of centrifugal force and continue to provide power for the electric surfboard. This intelligent driving method can not only effectively save the battery energy of the electric surfboard and extend the continuous working time, but also reduce the resistance of the surfboard in the water by folding the propeller 30, so that it can obtain a longer gliding distance and a faster gliding speed when there are waves, so that the user can get a better surfing experience.

[0059] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
