As preferable, the inside of the first connector 6 is hollow, and the first connector 6 is the part of inner hollow, so The buoyancy of electronic surfboard can be increased and reduce the total quality of electronic surfboard.The inside of mounting cylinder 7 is hollow, peace Fitted tube 7 is the part of inner hollow, so can equally increase the buoyancy of electronic surfboard and reduce the whole of electronic surfboard Weight.
As shown in Figures 1 to 5, drive device also includes the second connector 5 being connected with the first connector 6 and is arranged at Preceding fin 3 and tail fin 4 on second connector 5, mounting cylinder 7 is parallel with the second connector 5 and mounting cylinder 7 is located at the second connector Between 5 and surfboard body, preceding fin 3 and tail fin 4 are respectively arranged at one end of the second connector 5.As preferable, the second connection Part 5 is cylinder, and the axial direction of the second connector 5 is parallel with the axial direction (i.e. the length direction of mounting cylinder 7) of mounting cylinder 7.First One end of connector 6 is fixedly connected with surfboard body, the opposite side of the first connector 6 be the both ends of the second connector 5 it Between opening position be fixedly connected with the second connector 5, the length direction of the length direction of the first connector 6 and the second connector 5 (i.e. the axial direction of the second connector 5) is perpendicular.Mounting cylinder 7 is that the opening position between the both ends of the first connector 6 connects with first Fitting 6 is fixedly connected, and the second connector 5 is located at the lower section of mounting cylinder 7, and vertical between mounting cylinder 7 and the second connector 5 Distance is less than the vertical range between mounting cylinder 7 and surfboard body, so that and the resistance to overturning of electronic surfboard is more preferable, Better reliability.
As preferable, the inside of the second connector 5 is hollow, and the second connector 5 is the part of inner hollow, so The buoyancy of electronic surfboard can be increased and reduce the overall weight of electronic surfboard.
As shown in Figures 1 to 6, to accommodate the hollow cavity of battery, battery is used for electricity for the inside of surfboard body Motivation 13 provides electric energy.Battery case 11 is provided with the hollow cavity of surfboard body, battery is arranged in battery case 11.It is electronic Machine 13 realizes and electrically connected that wire 14 simultaneously passes through from the inner chamber of the connector 6 of mounting cylinder 7 and first by wire 14 with battery, It is powered by wire 14 to motor 13, the rotation of motor 13 is provided the driving force power of electronic surfboard, make water electric Surfboard can travel on no unrestrained calm water surface, so that surfing fan person enjoys ubiquitous surfing fortune It is dynamic.
As shown in Figures 1 to 7, surfboard body includes the upper plate lid 1 and lower plate lid 2 for being oppositely arranged and being connected, lower plate Lid 2 is fixedly connected with the first connector 6.Upper plate lid 1 is located at the top of lower plate lid 2, and upper plate lid 1 is that clamping is connected with lower plate lid 2, Upper plate lid 1 is parallel with lower plate lid 2, needs to seal between upper plate lid 1 and lower plate lid 2, reaches the effect of waterproof.Upper plate lid 1 is with The hollow cavity of surfboard body is formed between plate lid 2, surfboard can be made by the effect of the buoyancy of water static when Float on the surface, be unlikely to sink under water.
As shown in Figures 1 to 5, preceding fin 3 is fixedly connected with one end of the second connector 5 and preceding fin 3 is located at surfboard body Lower section, tail fin 4 is fixedly connected with the other end of the second connector 5 and tail fin 4 is located at the lower section of protective cover 8.Preceding fin 3 is arranged on The front end of second connector 5 and preceding fin 3 is parallel with upper plate lid 1 and lower plate lid 2, tail fin 4 be arranged on the rear end of the second connector 5 and Tail fin 4 is parallel with upper plate lid 1 and lower plate lid 2, and preceding fin 3 and tail fin 4 are in same horizontal line.As preferable, such as Fig. 9 institutes Show, the upper surface of preceding fin 3 and the surface area of lower surface differ, and the upper surface of preceding fin 3 is in the shape that raises up, preceding fin 3 The area of upper surface be more than lower surface area, when motor 13 operates, preceding fin 3 advances in water, due to preceding fin 3 it is upper, Following table area difference cause water flow through before the upper surface of fin 3 speed is different with the speed for flowing through lower surface and water flows through preceding fin 3 Speed during upper surface is more than speed when flowing through lower surface, because the flow velocity of the preceding upper surface of fin 3 is more than the flow velocity of lower surface, makes Fin 3 produces upward buoyancy in water before obtaining.As shown in Figure 10, the upper surface of tail fin 4 and the surface area of lower surface are to differ , the upper surface of tail fin 4 is in the shape that raises up, and the area of the upper surface of tail fin 4 is more than the area of lower surface, when motor 13 is transported When turning, tail fin 4 advances in water, due to tail fin 4 upper and lower surface product difference cause water flow through tail fin 4 upper surfaces speed and The speed for flowing through the upper surface that speed is different and water flows through tail fin 4 of lower surface is more than the speed for flowing through lower surface, due to tail fin 4 Upper surface flow velocity be more than lower surface flow velocity so that tail fin 4 produces upward buoyancy in water.
As shown in Figure 12 to Figure 13, when motor 13 is static, surfer can be static by the buoyancy of surfboard itself Swim on the water surface;When motor 13 is powered, because motor 13 drives the rotary speed of propeller 10 different so that preceding The gait of march of fin 3 and tail fin 4 in water is different, and the gait of march of preceding fin 3 and tail fin 4 in water is different so that the preceding He of fin 3 The caused buoyancy in water of tail fin 4 is different, and buoyancy with preceding fin 3 and tail fin 4 in water the increase of pace and become big;When When the drive propeller 10 of motor 13 reaches certain rotating speed, surfboard is being floated by preceding fin 3 and tail fin 4 caused by underwater exercise Power is enough the weight for bearing surfer, and at this moment lower plate lid 2 departs from the water surface, that is, is higher by the water surface, and the high highland of surfer can be made to jump out The water surface, as shown in figure 13.Motor 13 can be arranged to utilize controlled in wireless, and the controller held by surfer controls, control Device controlled motor ground rotating speed, driving surfboard travels forward, and turns then by surfer by adjusting body gesture control.
The present invention is exemplarily described above in association with accompanying drawing.Obviously, present invention specific implementation is not by above-mentioned side The limitation of formula.As long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress;Or not It is improved, the above-mentioned design of the present invention and technical scheme are directly applied into other occasions, in protection scope of the present invention Within.
