The utility model relates to a water sports equipment technical field especially relates to a bionical type water sports device.

Background

With the improvement of living standard, the water recreation and entertainment are more popular with the public, and correspondingly, a plurality of water recreation facilities including water walking shoes appear. Walking shoes on water are simple recreational apparatus suitable for single person. The people can freely walk on the water for thousands of years, the water advancing mode is mainly carried out in an integral sliding mode such as a manned boat raft and the like since ancient times, an innovative water walking mode in a double-foot discrete sliding mode such as buoyancy shoes, water walkers and the like appears in the current market, and the novel water walking mode is applied to the field of travel and leisure. The existing water walking mode realized by the drainage container modes of 'buoyancy shoes, water walkers' and the like is to essentially disassemble a ship into two ships, stand two feet of a human body in large shoes like the two ships respectively, and slide on water through the shoes to realize the walking of the human body. The shoes are bulky and hard to carry, the control of human body is difficult, the action is passively restricted, and the use effects of 'floating on water', body-building, leisure, pleasure, water operation, security, rescue and the like are difficult to realize.

Therefore, there is a need to design a water sports device with simple structure, portability and higher degree of freedom.

In order to solve the technical problem, the utility model provides a bionical type sport device on water, its simple structure, light in weight, the motion is nimble, and the operator can make the action of multiple land motion, has high sight.

The utility model provides a technical scheme as follows:

a biomimetic water sports device comprising:

a socket for securing a leg of a wearer;

the elastic support component is arranged on the lower side of the receiving cavity and is connected with the receiving cavity, and the elastic support component has elasticity and is used for supporting the weight of a wearer;

the flipper component is arranged on one side, away from the receiving cavity, of the elastic supporting component and comprises a drainage plate and movable wings, and the drainage plate is connected with one end, away from the receiving cavity, of the elastic supporting component; the movable wing is rotatably arranged on the side edge of the drainage plate, inclines towards one side of the receiving cavity and is used for swinging towards the upstream surface of the flipper component to generate buoyancy and impact force.

In this technical scheme, when using this equipment, the motion state is relevant with the head direction of activity wing, and the head direction of activity wing and user's face syntropy, then the shank drive the device and kick forward and step on water and just can produce ascending lift, otherwise then the shank drive the device and kick backward and step on water and produce ascending lift. Take the direction of the head of the movable wing opposite to the direction of the face of the user as an example: when the legs of the human body enter the socket, the legs can be moved in a running mode on land to obtain enough upward force to support the gravity of the body so as to be capable of doing sports on water. The first step on the legs and the water: when the leg stretching action is carried out, the movable wings on the drainage plate have certain upward inclination, and when the movable wings start to be in a folded state and contact the water surface, the movable wings extend quickly due to the fact that the movable wings have certain upward inclination, so that the drainage plate moves downwards. The legs are pedaled backwards, the web surface in the vertical direction interacts with water to generate buoyancy and impact force, the movable wings and the water move relatively in the horizontal direction, the water flow which moves backwards flows forwards, the water flow forms pressure difference through the flipper components to generate lift force, and when the lift force is enough, the gravity of the human body can be supported. The human body has a vertical downward motion state under the action of gravity, so that the receiving cavity is close to the drainage plate, and the elastic supporting component stretches and stores certain gravitational potential energy to provide certain power for the next leg pedaling. When the leg is folded, the movable wings are quickly folded when the movable wings have certain upward inclination and the water discharging plate moves upwards under the elastic action of the elastic parts on the movable wings, the elastic supporting assembly is changed from a stretching state to a contracting state, and the receiving cavity is far away from the water discharging plate. The first step of pedaling and water treading is finished and the second step of pedaling is carried out, so that the human body can dynamically stay on the water surface repeatedly. Because the movable wings incline upwards, the stability of the rolling is improved, the user can be ensured to turn sharply when the user leans on his side, the movable wings cannot roll immediately when the gravity center moves laterally, the user falls into water, the operability of the user is improved, and the sport is more ornamental.

It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort.

As a specific embodiment, as shown in fig. 1 and 2, the present embodiment provides a bionic water sports device, including: a receiving cavity 1, an elastic supporting component 2 and a flipper component 3. Wherein the receiving cavity 1 is used for fixing the leg of the wearer, the receiving cavity 1 can be in a contractible structure. The elastic support component 2 is arranged on the lower side of the receiving cavity 1, and the elastic support component 2 is arranged on the lower side of the receiving cavity 1 and is fixedly connected with the receiving cavity 1. The elastic support component 2 is of an arc-shaped structure and has elasticity, is used for supporting the weight of a wearer and can be made of carbon fiber materials. The flipper component 3 is arranged on one side of the elastic supporting component 2 far away from the receiving cavity 1, the flipper component 3 comprises a drain board 31 and a movable wing 32, and the drain board 31 is connected with one end of the elastic supporting component 2 far away from the receiving cavity 1. The movable wing 32 is rotatably provided at a side of the drain plate 31 and is inclined toward a side of the socket 1, and may be inclined in a radian or an inclined plane, for generating buoyancy and impact force toward the upstream face of the flipper assembly. The upstream surface of the fin assembly refers to a surface of one side of the fin assembly which is subjected to water flow impact during water flapping. Meanwhile, the movable wing 32 can reduce the water-facing area and further reduce the resistance when the leg is folded, thereby achieving the purpose of saving labor.

In practical application, when the device is used, the motion state is related to the head direction of the movable wing 32, the head direction of the movable wing 32 is the same as the face of a user, the legs drive the device to kick forward and tread on water to generate upward lift force, otherwise, the legs drive the device to kick backward and tread on water to generate upward lift force. Taking the direction of the head of the movable wing 32 opposite to the face of the user as an example: when the legs of the human body enter the socket 1, the legs are moved by running on the land so that the legs themselves obtain a force upward enough to support the weight of the body to enable the sport of work on water. The first step on the legs and the water: in the leg stretching action, the movable wing 32 on the drain board 31 has a directional inclination, and when the drain board 31 is in the folded state and contacts the water surface, the movable wing 32 is rapidly extended when the movable wing 32 moves downwards due to a certain upward inclination. The legs are pedaled backwards, the web surface in the vertical direction interacts with water to generate buoyancy and impact force, the movable wing 32 and the water move relatively in the horizontal direction, the movable wing 32 moves backwards, water flows forwards, the water flows through the fin assembly 3 to form pressure difference to generate lift force, and when the lift force is enough, the gravity of the human body can be supported. The human body has a vertical downward motion state under the action of gravity, so that the receiving cavity 1 approaches to the drainage plate 31, and the elastic part is stretched to store certain gravitational potential energy to provide certain power for the next leg pedaling. In the leg-folding action, once again, because the movable wing 32 has a certain upward inclination and the elastic action of the elastic part on the movable wing 32 makes the drain board 31 move upward, the movable wing 32 is quickly folded, the elastic support assembly 2 is changed from the stretching state to the shrinking state, and the receiving cavity 1 is far away from the drain board 31. The first step of pedaling and water treading is finished and the second step of pedaling is carried out, so that the human body can dynamically stay on the water surface repeatedly. Because the movable wings 32 incline upwards, the rolling stability is improved, the user can be ensured to turn sharply when the user leans on one side, the movable wings 32 cannot roll immediately when the gravity center moves laterally, the user falls into water, the operability of the user is improved, and the sport is more ornamental.
