[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, a water power mechanism 100 is provided, comprising a driving assembly 110, a front wing plate 120 and a rear wing plate 130. The driving assembly 110 comprises a driver 111, a propeller blade 112 and a slide rail 113. The driver 111 is drivingly connected to the propeller blade 112, and the driver 111 is used to drive the propeller blade 112 to rotate. The slide rail 113 is arranged on the outer surface of the driver 111, and the slide rail 113 is provided with a slide groove 113a. The front wing plate 120 is connected to an end of the driver 111 away from the propeller blade 112. The rear wing plate 130 is slidably connected to the inner side wall of the slide groove 113a, and the rear wing plate 130 and the front wing plate 120 are arranged at a distance from each other.

[0029] It should be noted that the driver 111 is a driving source. In this embodiment, the driver 111 adopts a motor, and a submersible motor that can be used in water is adopted to ensure the normal driving function in the water body. The driver 111 can also adopt other driving devices that can realize rotational drive, which will not be described in detail in this embodiment. The output end of the driver 111 is connected to the propeller blade 112 for driving, so as to drive the propeller blade 112 to rotate in a directional manner to generate a spiral thrust, thereby serving as a driving source to provide driving force for the movement of the surfboard body. The front wing plate 120 and the rear wing plate 130 are respectively installed on the driver 111 at intervals from each other. The front wing plate 120 and the rear wing plate 130 are respectively installed on the driver 111. 130 are used to adjust the lifting force and the downward pulling force respectively. Specifically, the overall shape of the front wing panel 120 is set to be a wing shape that is spread downward. By forming different pressure differences between the upper and lower surfaces of the front wing panel 120 in the water body, lift is obtained using Bernoulli's theorem. The rear wing panel 130 is opposite to the front wing panel 120. The overall shape is set to be a wing shape that is spread upward. Similarly, by forming different pressure differences in the water body, the rear wing panel 130 obtains downward pulling force. According to the flow conditions of the water body and the water surface conditions, the user can timely adjust the balance of the surfboard body on the water surface by applying different forces to the front wing panel 120 and the rear wing panel 130.

[0030] Furthermore, by providing a slide rail 113, the slide rail 113 is installed on the outer shell of the driver 111, and the slide rail 113 is arranged along the length direction of the driver 111, and the slide rail 113 is provided with a slide groove 113a arranged along the length direction of the driver 111, so that a sliding track moving along the length direction of the driver 111 can be provided, and the front wing plate 120 is fixedly installed on the end of the driver 111 away from the propeller blade 112, and the rear wing plate 130 is slidably installed on the slide rail 113, and can be moved along the slide groove 113a of the driver 111. The rear wing 130 can slide along the slide rail 113 to adjust the position of the rear wing 130 according to the weight and body shape of the user, thereby adjusting the distance between the front and rear wings 120 and the front wing 120, so as to adjust the position and distance between the front and rear wings 120 and the rear wing 130 when the front and rear wings 120 are installed on the surfboard body, so that the user can adjust the position and distance between the front and rear wings 120 and the rear wing 130 when the front and rear wings 120 are installed on the surfboard body. The positions and intervals at which the user applies forces to the front wing panel 120 and the rear wing panel 130 are different, so that it can be adapted to users of different weights and body shapes. For example, when the user's weight and body shape are small, the interval between the forces applied by the user is small, and the rear wing panel 130 can be moved closer to the front wing panel 120 by sliding the rear wing panel 130 to reduce the interval between the front wing panel 120 and the rear wing panel 130, so that the user can more easily apply forces to the front wing panel 120 and the rear wing panel 130, and adjust them more easily, thereby reducing the difficulty of surfing and improving the surfing experience. On the contrary, When the user's weight and body size are larger, the distance between the forces applied by the user becomes larger, and the distance between the front wing board 120 and the rear wing board 130 can be correspondingly increased, so that the user can also control the surfboard body more easily and improve the surfing experience. In other words, the distance and position between the front wing board 120 and the rear wing board 130 can be adjusted according to users of different weights and body sizes to adapt to different users, so that the user can more easily adjust the front wing board 120 and the rear wing board 130 in time, and the adjustability is convenient for users to select and use.

[0031] See also Figure 3 and Figure 4In one embodiment, a slider 140 is further included, and the slider 140 is slidably disposed in the slide groove 113a, and the rear wing plate 130 is connected to the slider 140. It can be understood that by providing the slider 140, the slider 140 is adapted to the shape of the slide groove 113a, the slider 140 is slidably installed in the slide groove 113a, and the slide groove 113a can prevent the slider 140 from escaping from the slide groove 113a, thereby preventing the rear wing plate 130 from escaping from the slide groove 113a, and the rear wing plate 130 is slidably installed in the slide groove 113a through the slider 140, so as to realize the sliding connection between the rear wing plate 130 and the slide rail 113, thereby realizing the adjustment of the distance between the rear wing plate 130 and the front wing plate 120.

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, a connecting rod 150 is further included, wherein a first end of the connecting rod 150 is connected to the slider 140, and a second end of the connecting rod 150 is connected to the rear wing 130. It can be understood that since the rear wing 130 is a wing-shaped structure, the connecting rod 150 is provided, and the connecting rod 150 is a long rod-shaped structure, and the two ends of the connecting rod 150 are respectively connected to the slider 140 and the rear wing 130, thereby realizing the connection between the rear wing 130 and the slider 140, and the rear wing 130 is more stably and firmly installed on the slider 140, with a better installation effect and easy processing and forming.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4In one embodiment, the first end of the connecting rod 150 is provided with a first guide portion 151, and the cross-sectional area of ​​the first guide portion 151 gradually decreases from the end close to the rear wing plate 130 to the end away from the rear wing plate 130. The second end of the connecting rod 150 is provided with a second guide portion 152, and the cross-sectional area of ​​the second guide portion 152 gradually decreases from the end close to the slider 140 to the end away from the slider 140. It can be understood that in this embodiment, by providing the first guide portion 151 and the second guide portion 152 at the first end and the second end of the connecting rod 150 respectively, and the first guide portion 151 and the second guide portion 152 are both configured in a cone shape, specifically, the first guide portion 151 is an end portion of the connecting rod 150 close to the front wing plate 120, and the front wing plate 120 is in the forward direction. At this time, the first guide portion 151 moves forward against the water flow. At this time, the first guide portion 151 is configured in a cone shape, which can greatly reduce the resistance and play a good backward guiding role for the water flow. When the water flows to the second guide part 152, the second guide part 152 further reduces the resistance and guides the water, thereby reducing the loss of the driving force of the driver 111, and ensuring that the water power mechanism provides sufficient driving force, thereby enhancing the excitement of the user when surfing. Moreover, under the synchronous guidance of the first guide part 151 and the second guide part 152, the water flows smoothly, minimizes the occurrence of water turbulence, reduces the fluctuation of the surfboard body, and is conducive to the user to control the surfboard body more easily, further reduces the difficulty of surfing, and enhances the surfing experience.

[0034] See also Figure 3 and Figure 4 In one embodiment, a locking piece is further included. The slider 140 is provided with a through hole 101. The locking piece passes through the through hole 101 and is movably connected to the inner wall of the slide groove 113a. The slider 140 is provided with through holes 101 that pass through the two side surfaces of the slider 140. At the same time, a locking piece is provided. After the locking piece passes through the through holes 101, it is inserted into the slide groove 113a and movably connected with the inner side wall of the slide groove 113a. Specifically, when it is necessary to adjust the position of the rear wing plate 130, the locking piece is moved away from the inner side wall of the slide groove 113a and disconnected from the inner side wall. Then, the position of the rear wing plate 130 is adjusted by sliding the slider 140, thereby adjusting the distance between the rear wing plate 130 and the front wing plate 120. After the position of the rear wing plate 130 is adjusted, the locking piece is inserted into the slide groove 113a and connected with the inner side wall of the slide groove 113a to lock the position of the slider 140, thereby locking the position of the rear wing plate 130, preventing the rear wing plate 130 from sliding during surfing, and ensuring the normal use of the water power mechanism. The structure is simple and convenient for users to adjust.

[0035] See also Figure 3 and Figure 4 In one embodiment, the locking member includes a bolt 160, an inner wall of the through hole 101 is provided with an internal thread, and the bolt 160 is threadedly connected to the internal thread. It can be understood that in this embodiment, the locking member adopts a bolt 160, and the matching through hole 101 is set to a threaded hole structure with an internal thread. The bolt 160 is threadedly connected with the threaded hole on the inner wall of the through hole 101 and can be detachably installed on the slider 140. By further twisting the bolt 160, the bolt 160 is directed to enter the slide groove 113a. By further twisting the bolt 160, the bolt 160 is abutted and connected with the inner wall of the slide groove 113a, and a resisting force is generated on the inner wall of the slide groove 113a to prevent the slider 140 from sliding further, thereby locking and fixing the slider 140. The bolt 160 is twisted in the reverse direction to disconnect the bolt 160 from the inner wall of the slide groove 113a, so that the slider 140 can be slid again and the position of the slider 140 can be readjusted, thereby adjusting the position of the rear fender 130. The structure is simple and the adjustment is easy.

[0036] See also Figure 3 , Figure 4 and Figure 6 In one embodiment, the inner wall of the chute 113a is provided with a wear-resistant layer 102, and the locking piece is movably connected to the wear-resistant layer 102. It can be understood that by providing the wear-resistant layer 102 on the inner wall of the chute 113a, for example, a hard sheet metal is inlaid on the inner wall of the chute 113a as the wear-resistant layer 102, which can be used to connect with the locking piece, avoiding the friction caused by the direct connection between the locking piece and the inner wall of the chute 113a, thereby protecting the inner wall of the chute 113a, effectively improving the service life of the chute 113a, and improving the overall structural stability and service life of the water power mechanism.

[0037] See also Figure 3 , Figure 4 and Figure 6In one embodiment, a protrusion 113b is provided on the inner side wall of the slide groove 113a, and the protrusion 113b is inclined gradually from one end close to the inner side wall of the slide groove 113a to the other end toward a direction away from the connecting rod 150. The slider 140 is provided with a locking groove 141, and the inner side wall of the locking groove 141 is slidably connected to the protrusion 113b. It can be understood that by providing the protrusion 113b, the protrusion 113b is arranged obliquely upward, and correspondingly, the shape and position of the engaging groove 141 are adapted to the protrusion 113b. On the one hand, the protrusion 113b can play an anti-escape effect to prevent the slider 140 from escaping from the slide groove 113a. On the other hand, the protrusion 113b is arranged obliquely upward, which can play a certain supporting role on the slider 140, so that the slider 140 is more firmly and stably installed on the slide rail 113, so that the rear wing plate 130 is more stably installed on the slide rail 113, which is beneficial to improve the overall structural stability of the water power mechanism. Specifically, two protrusions 113b can be provided, and two engaging grooves 141 are also provided accordingly, which support and prevent the slider 140 from falling out from the left and right sides respectively.

[0038] See also Figure 3 , Figure 4 and Figure 6 In one embodiment, the protrusion 113b is provided with a first arc surface 113c, and the engaging groove 141 is provided with a second arc surface 141a, and the first arc surface 113c is in contact with the second arc surface 141a. It can be understood that the protrusion 113b and the engaging groove 141 are respectively provided with a first arc surface 113c and a second arc surface 141a, so that the surfaces of the protrusion 113b and the engaging groove 141 have a smooth arc surface structure. Since the water power mechanism will be subjected to the impact force of the water body when used in the water body, under the action of the impact force of the water body, a certain friction will be generated between the protrusion 113b and the inner wall of the engaging groove 141. The arc surface structure can convert the friction between the protrusion 113b and the inner wall of the engaging groove 141 into rolling friction, which is beneficial to greatly reduce the friction force between the protrusion 113b and the inner wall of the engaging groove 141, reduce the wear between the protrusion 113b and the inner wall of the engaging groove 141, and help to increase the service life of the slider 140 and the slide rail 113, thereby increasing the overall service life of the water power mechanism.

[0039] See also Figure 1 , Figure 2 and Figure 3In one embodiment, the electric power source 111 further includes a support rod 170, which is connected to the outer surface of the driver 111. It can be understood that in this embodiment, the support rod 170 is a hollow rod-shaped structure, which is conducive to reducing the weight of the support rod 170 and reducing the loss of the driving force of the driver 111. At the same time, the electric wire connecting the driver 111 and the external power supply device can be installed inside the support rod 170, which plays a certain protective role on the electric wire. By providing the support rod 170, the support rod 170 is vertically installed on the driver 111, and the support rod 170 can be installed on one end of the driver 111 close to the front wing 120. The support rod 170 is a long rod-shaped structure, and the other end of the support rod 170 is used to connect with the surfboard body, so as to realize the connection and installation of the surfboard body and the water power mechanism, and realize the normal driving of the surfboard body by the water power mechanism, so as to realize the surfing function of the electric surfboard.

[0040] In one embodiment, the cross section of the support rod 170 is in the shape of a water drop. It is understandable that the support rod 170 is set in the shape of a water drop so that the surface of the support rod 170 has a smooth arc, which avoids causing resistance to the water flow, greatly reduces the resistance of the water power mechanism when in use, avoids power loss, and is conducive to enhancing the excitement of surfing.

[0041] See also Figure 4 and Figure 5 In one embodiment, the duct assembly 180 is further included, and the duct assembly 180 includes an inner guide duct body 181, an outer ring guide duct body 182 and a connecting rib 183. The inner guide duct body 181 is connected to the driver 111, and the two ends of the connecting rib 183 are respectively connected to the inner guide duct body 181 and the outer ring guide duct body 182. The outer ring guide duct body 182 covers the outer side of the propeller blade 112. It can be understood that by providing an inner guide channel body 181, the inner guide channel body 181 is connected to one end of the driver 111 provided with an output end, and is covered on the outer side of the output end of the driver 111. The inner guide channel body 181 is provided with a movable through-hole so that the output end of the driver 111 passes through the movable through-hole. The outer ring guide channel body 182 is fixedly mounted on the inner guide channel body 181 through the connecting ribs 183 to form a hollow ring structure. The outer ring guide channel body 182 at least partially covers the outer side of the propeller blade 112, which can provide a certain covering and protection effect on the propeller blade 112, preventing the propeller blade 112 from being directly impacted by the water body, which is beneficial to improving the service life of the water power mechanism. At the same time, by providing the inner guide channel body 181 and the outer ring guide channel body 182 structure, the water swept backward by the propeller blade 112 can be gathered, so that the swept water flows as consistently as possible backward to obtain the maximum kinetic energy to push the surfboard body forward, thereby further improving the surfing experience.

[0042] In one embodiment, the cross-sectional area of ​​the connecting rib 183 gradually decreases from one end close to the inner guide channel body 181 to one end away from the inner guide channel body 181. It can be understood that the connecting rib 183 is used to connect the inner guide channel body 181 and the outer ring guide channel body 182, and the stress of the connecting rib 183 at the connection point of the inner guide channel body 181 is the largest. At this time, the connection point between the connecting rib 183 and the inner guide channel body 181 is set to have the largest cross-sectional area, which can ensure that the connecting rib 183 is firmly installed on the inner guide channel body 181. At the same time, in order to minimize the resistance to the water flow, by setting the cross-sectional area of ​​the connecting rib 183 to gradually decrease from one end close to the inner guide channel body 181 to one end away from the inner guide channel body 181, it is beneficial to reduce the volume and surface area of ​​the connecting rib 183, and can also play a certain role in diversion, greatly reducing the resistance to the water flow, and further improving the surfing experience.

[0043] In one embodiment, an electric surfboard is further provided, comprising a surfboard body, and also comprising: the water power mechanism described in any of the above embodiments, wherein the water power mechanism is connected to the surfboard body.

[0044] It should be noted that the surfboard body is installed on the water power mechanism by connecting to the end of the support rod away from the driver. The driver drives the propeller blades to rotate to provide driving force for the surfboard body. By adjusting the position of the rear wing, the distance between the rear wing and the front wing is adjusted, thereby adjusting the position and distance between the front wing and the rear wing in the vertical direction corresponding to the surfboard body, which is conducive to adapting to users of different weights and body shapes. The electric surfboard is adjustable, which is convenient for users to select and use, and greatly reduces the difficulty of surfing for users and improves the user's experience.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] The present invention provides a driver for driving the propeller blades to rotate and generate a spiral driving force as a driving source to provide driving force for the movement of the surfboard body. The present invention also provides a slide rail, which can provide a sliding track. The front wing plate and the rear wing plate are respectively installed on the driver at intervals from each other. The front wing plate and the rear wing plate are respectively used to adjust the lifting force and the downward pulling force, so as to facilitate timely adjustment of the balance of the surfboard body on the water surface. The rear wing plate is installed on the slide rail by sliding. In this way, the rear wing plate can be slid on the slide rail according to users of different weights and body shapes, so as to adjust the rear wing plate according to users of different weights and body shapes. The position of the board can be adjusted to adjust the front-to-back distance between the rear wing and the front wing, thereby adjusting the front-to-back position and distance between the front wing and the rear wing when they are installed on the surfboard body, so that the position and distance at which the user applies force to the front wing and the rear wing are different, so that it can be adapted to users of different weights and body shapes. In other words, the distance and position between the front wing and the rear wing can be adjusted according to users of different weights and body shapes to adapt to different users, making it easier for users to adjust the front wing and the rear wing in time, and the board is adjustable to facilitate user selection and use.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
