Examples

Electric surfboards are usually provided with a propeller to provide power for accelerating surfing, but a hydrofoil is generally required to be arranged on the basis of the propeller to fly off the water surface.

However, the use of hydrofoils to raise the board and maintain a constant flight height after raising (flight here means that the board for the standing person leaves the water surface and remains there for a period of time) requires skilled operating skills. For example, the posture of the board body is adjusted by adjusting the posture of the body, and the posture of the hydrofoil connected to the board body is adjusted, so that the operation is difficult for a general user, a large amount of training is required for realizing the operation, and the door threshold is high.

The application provides an electronic surfboard for solve the problem of the electronic surfboard of the operation of not being convenient for in order to fly away from the surface of water.

As shown in fig. 1, the electric surfboard includes a surfboard body 100, a mounting base 200, a propeller 300, and an adjustment device 400.

The lower surface of the surfboard body 100 is used to contact the water surface, and the upper surface of the surfboard body 100 is used to stand a person.

The mounting base 200 is attached to the bottom of the surfboard body 100 and extends downward from the lower surface of the surfboard body 100.

The propeller 300 is provided to the mounting base 200 for providing a propelling force, and the propeller 300 can swing with respect to the mounting base 200, and the direction of the propelling force is different when the propeller 300 swings to different angles with respect to the mounting base 200.

The adjusting device 400 is provided to the mounting base 200 for driving the propeller 300 to swing, thereby adjusting the direction of the propulsion force.

Generally, the surfboard body 100 floats on the water surface, the mounting base 200, the propeller 300 and the adjustment device 400 are located under the water, the propeller 300 is horizontally drained backwards, and the water body provides a forward reaction force, i.e., a propelling force, to the whole surfboard body, so that the surfboard body 100 moves forwards.

When the rising is needed, as shown in fig. 2, the adjusting device 400 drives the propeller 300 to swing downwards, and when the propeller 300 swings downwards, the propeller 300 does not swing to be completely vertical downwards, but swings downwards at a certain angle relative to the horizontal plane, and at the moment, the propeller 300 drains towards the oblique lower direction, so that the water body provides a propelling force towards the oblique upper direction to the whole surfboard, the propelling force has a forward component and an upward component, and the surfboard body 100 is accelerated to rise to be away from the water surface under the action of the propelling force and moves forwards.

When the surfboard rises to a certain height, the adjusting device 400 drives the propeller 300 to swing upwards and backwards for a certain angle, at the moment, the propeller 300 still faces obliquely below for draining water, the direction of the propulsion force still faces obliquely above, but the vertical component force of the propulsion force is reduced, and when the vertical component force of the propulsion force is reduced to be balanced with the gravity of the whole surfboard and the buoyancy of the whole surfboard, the surfboard body 100 is kept at a certain height.

Therefore, the electric surfboard provided by the embodiment adjusts the direction of the propelling force of the propeller 300 through the adjusting device 400, so that the surfboard body 100 flies away from the water surface, a certain height can be kept on the water surface, the operation is simple and convenient, and the problem that the electric surfboard is not convenient to operate so as to fly away from the water surface is solved.

When the surfboard body 100 needs to be returned to the water surface, the adjustment device 400 drives the propeller 300 to swing back upward.

For example, the propeller 300 swings back to the horizontal to provide only a propulsive force backward, thereby breaking the force balance state and allowing the surfboard body 100 to fall.

If the propeller 300 swings back to the horizontal and continues to swing upward, as shown in fig. 3, the upward swing of the propeller 300 does not mean swinging to a completely vertical direction, but swings upward at a certain angle with respect to the horizontal plane, and at this time, the propeller 300 drains water obliquely upward, so that the water body provides an obliquely downward propelling force to the entire surfboard, the propelling force has a forward component and a downward component, and the surfboard body 100 moves forward while accelerating back to the water surface under the action of the reaction force.

When the surfboard has returned or is about to return to the water surface, the adjustment means 400 drives the propeller 300 to be kept horizontal, only the backward propulsive force is provided, both the gravity of the surfboard as a whole and the buoyancy of the surfboard as a whole are balanced, and the surfboard body 100 floats on the water surface.

The aforementioned mounting substrate 200 includes a first portion 210 and a second portion 220.

The upper end of the first portion 210 is connected to the surfboard body 100, and the lower end of the first portion 210 is connected to the second portion 220.

The second portion 220 extends rearward from the lower end of the first portion 210 to form a mounting location.

The pusher 300 is mounted to the first part 210 and the adjustment device 400 is mounted to the second part 220 at a mounting location.

In some embodiments, the first portion 210 extends downward from the bottom of the surfboard body 100 a distance such that the propeller 300 can penetrate into the water when the surfboard body 100 is floating on the water surface, thereby enabling the surfboard body 100 to reach a higher flying height.

The arrangement of the first portion 210 extending a distance downward from the bottom of the surfboard body 100 also provides the surfboard body 100 with more adjustable height to prevent the propeller 300 from being too quickly out of the water, which would result in too short an operational time for the propeller 300 to be out of the water, and an extended operational time that would allow the operator to have enough reaction time to further solve the problem of inconvenient operation.

The aforementioned propeller 300 includes a motor 310, a flexible coupling 320, and a propeller assembly 330.

A motor 310 is provided to the mounting base 200, and an output shaft of the motor 310 is connected to a propeller assembly 330 by a flexible coupling 320.

When the propulsion force is adjusted, the motor 310 is fixed, the flexible coupling 320 is deformed, and the propeller assembly 330 is integrally swung to change the drainage direction thereof, thereby changing the direction of the propulsion force.

The propeller assembly 330 includes a propeller 331 and a propeller mount 332.

The propeller mounting seat 332 is provided with a bearing, and the rotating shaft of the propeller 331 penetrates through the bearing and is connected with the flexible coupling 320.

To improve stability, propeller mount 332 is connected to mounting base 200 by flexible rod 340. As shown in fig. 4, one end of the flexible rod 340 is connected to the mounting substrate 200, or to the surface of the motor 310, i.e., one end of the flexible rod 340 is fixed with respect to the mounting substrate 200; the other end of the flexible rod 340 is fixedly connected with the propeller mounting base 332.

The flexible rod 340 includes a plurality of flexible rods 340, and the plurality of flexible rods 340 are arranged along the circumference of the propeller mounting base 332.

Further, a plurality of flexible rods 340 are uniformly distributed along the circumference of the propeller mounting base 332.

The output of the adjustment device 400 is connected to the propeller mount 332.

The adjusting device 400 includes a linear driving module 410 and a link 420.

Referring to fig. 4 and 5, the linear driving module 410 is disposed in the second portion 220.

The second portion 220 is provided with a strip-shaped groove, and the extension direction of the strip-shaped groove is the same as the driving direction of the linear driving module 410.

One end of the link 420 is connected to the output end of the linear driving module 410, and the other end of the link 420 is hinged to the propeller mounting base 332.

In order to improve the force balance of the propeller mounting base 332, a pair of clipping arms 421 are formed at the other end of the connecting rod 420, the pair of clipping arms 421 are respectively arranged at both sides of the propeller mounting base 332, and the pair of clipping arms 421 are respectively rotatably connected to the propeller mounting base 332.

The hinge can be a rotating shaft connection, and can also be other hinge modes with certain degrees of freedom. The rotatable connection can be a rotating shaft connection, and can also be other rotatable connection modes.

Under the combined action of the pair of clamp arms 421, the propeller mounting base 332 is stressed in a balanced manner, can swing up and down stably, and can avoid deflection to the left and right sides due to uneven stress, so that the phenomenon that the surfboard turns on one side due to the disordered propelling force is avoided.

In some embodiments, the linear drive module 410 includes a lead screw nut assembly.

As shown in fig. 6, the screw shaft 411 is disposed in the cavity of the second portion 220 and extends along the second portion 220, the nut 412 is screw-coupled to the screw shaft 411 so as to move back and forth along the screw shaft, and the link 420 is coupled to the nut 412.

The linear driving module 410 further includes a step motor (not shown), and an output end of the step motor is connected to the lead screw 411 for driving the lead screw 411 to rotate so as to drive the nut 412 and one end of the connecting rod 420 to move.

When the nut 412 is directly under the propeller assembly 330, the link 420 is vertical, the propeller assembly 330 is horizontally drained backwards, and the propulsive force is horizontally forward.

When the nut 412 moves forward from the right below of the propeller assembly 330, the connecting rod 420 drives the propeller assembly 330 to swing downward, the propeller assembly 330 discharges water obliquely downward, and the propelling force is directed obliquely upward.

When the nut 412 moves from the right below of the propeller assembly 330 to the rear, the connecting rod 420 drives the propeller assembly 330 to swing upwards, the propeller assembly 330 discharges water towards the oblique upper direction, and the propelling force faces the oblique lower direction.

In other embodiments, the linear driving module 410 may also be a pneumatic cylinder, an electric cylinder, or the like. The piston rod of the cylinder or the electric cylinder is connected to one end of the connecting rod 420.

When the first sensor 510 is close to or exposed out of the water, the height of the surfboard body 100 is high, and the propeller 300 is easily separated from the water, so that the surfboard body 100 is suitable to descend by a certain height.

The height of the surfboard body 100 is moderate when the second sensor 520 is near or out of the water, and can be maintained at that height if the surfboard body needs to continuously fly off the water.

When the third sensor 530 approaches or is exposed out of the water, the height of the surfboard body 100 is low, and the surfboard body 100 is in a floating state on the water.

If the working mode of the electric surfboard is a mode of flying off the water surface:
