Description

Technical Field

[0001] The invention relates to the technical field of water skis, and in particular to a multi-control type electric water ski and a forming process thereof. Background Art

[0002] As a water sports equipment, water skis have always been loved by sports enthusiasts. Traditional water skis usually rely on human power or the traction of external boats to achieve sliding, which to a certain extent limits the autonomy and flexibility of water skiing. With the continuous development of science and technology, electric drive technology has gradually been applied to the field of water skis, bringing new experience to water skiing.

[0003] Most of the existing water skis are fuel-powered, which have the following deficiencies or disadvantages: 1) Burning fuel will emit exhaust gas, which contains pollutants such as carbon monoxide, hydrocarbons, nitrogen oxides and particulate matter. These exhaust gases will have a negative impact on air quality, especially in open spaces around water bodies, which may affect the health of nearby residents and tourists. 2) Fuel leakage is a potential problem. If the fuel system of the water ski fails or is improperly operated during the refueling process, fuel may leak into the water. Fuel leakage will pollute the water body and cause danger to aquatic life. In addition, the leaked fuel will form an oil film on the water surface, preventing oxygen from dissolving into the water and affecting the breathing of aquatic life. In addition, harmful substances in the fuel may be absorbed by aquatic life and transferred through the food chain, which will have a long-term negative impact on the entire ecosystem. 3) Fuel-powered water skis usually produce loud noises, especially when running at high speeds. This noise will disturb the surrounding environment and affect the tranquility of nearby residents, wildlife and other water activities.

[0004] It can be seen that most of the existing powered water skis are fuel-powered water skis, which have the problems of poor environmental protection and noise pollution. Summary of the invention

[0005] The purpose of the present invention is to provide a multi-control type electric water ski and a forming process thereof, which solves the problems of poor environmental protection and noise pollution of the existing power water ski.

[0012] Preferably, the water ski body is made of high-strength lightweight material, and the angle between the seesaw and the water ski body is 15-25°.

[0013] A forming process of a multi-control type electric water ski comprises the following steps: S1. Use mold forming technology to process high-strength lightweight materials into the required shape; during the manufacturing process, ensure that the surface of the board is smooth, free of bubbles and cracks to improve the buoyancy and strength of the board; S2.

[0019] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0021] Example like Figure 1-6 As shown, the present invention provides a multi-control type electric water ski, including a water ski body 1, a seesaw 11 is installed at the front end of the water ski body 1, a handle 2 and an anti-skid pad 7 are installed on the upper surface of the water ski body 1, a control button is arranged on the handle 2, and a standing pull rope 3 is also installed on the handle, a waterproof cylinder 8 is fixedly installed at the center of the bottom surface of the water ski body 1, and the waterproof cylinder 8 is electrically connected to two propellers 10 embedded at the tail of the bottom surface of the water ski body 1 through a waterproof line, and a tail fin 9 is fixedly arranged between the two propellers 10. The two propellers 10 control the forward and reverse directions respectively, that is, one of them is a propeller (forward) and the other is a propeller (reverse). The propeller 10 includes a motor, a propeller and a transmission device. The motor drives the propeller to rotate through the transmission device to provide the water ski as a whole with forward power. The control module is used to control the speed and direction of the motor to realize the forward, backward and steering operations of the water ski, and has the function of setting the regional navigation electronic fence and returning to the home by the control key. The battery pack provides electrical energy for the power system and the control system, and the waterproof cylinder 8 is used to protect the internal battery pack and the circuit components of the electric control module from being corroded by water.

[0022] The motor drives the propeller through the transmission device. The magnetic coupling transmission technology of the propeller is a new technology that relies on the magnet array in the propeller housing 10 to drive the magnet array in the propeller hub to achieve contactless and leakage-free transmission of torque (power). Compared with the traditional rigid coupling, the magnetic coupling structure does not have components such as rotating shafts and shaft seals, which solves the problem of easy leakage of underwater rotating sealing mechanisms in principle. In addition, when overloaded, the magnetic coupling mechanism will play a role similar to a ratchet to prevent damage caused by the propeller being blocked by objects when the propeller is working.

[0023] The motor is a special motor designed for underwater environment, which has the characteristics of small size, light weight, high power and high torque. This motor, combined with a small and high-precision reducer, can more effectively reduce the weight of the propeller and improve the overall performance of the propeller.

[0024] The motor in the propeller 10 drives the propeller to rotate, sucking water from the suction surface of the blade and discharging it from the discharge surface, and using the reaction force of the water to propel the boat forward. Adding a deflector to the outer edge of the propeller of the propeller can increase the thrust by 30-35% to meet the needs of navigation. The propeller of the propeller is made of one-piece stainless steel material with high hardness and stronger corrosion resistance.

[0025] The propeller 10 in the present invention is an all-metal underwater propeller, which uses advanced magnetic coupling drive technology, which greatly reduces the impact and vibration during the operation of the propeller and extends the service life of the propeller. All electrical components are absolutely sealed in a sealed cabin to reduce the risk of seal leakage. The integrated design of mechanical, electrical and propeller and the precision process have brought the product efficiency, noise, power density and other parameters to the extreme. Excellent overheating protection, overcurrent protection and other functions ensure the reliability of product operation. Special metal surface treatment technology ensures the mechanical strength and salt spray corrosion resistance of the product.

[0026] The handle 2 includes a left handle 21 and a right handle 22, and the left handle 21 and the right handle 22 are respectively provided with a standing pull rope 3. Therefore, the present invention can realize two operation modes, one is handle control, and the other is standing pull rope control. The water ski operator sends instructions to the control through the control button. Both operation modes are simple, intuitive, easy to operate, and waterproof.

[0027] The control buttons include a backward control button 5 , a forward control button 4 and a standing control button 6 . The backward control button 5 and the forward control button 4 are respectively arranged on the left handle 21 and the right handle 22 , and the standing control button 6 is arranged on the standing pull rope 3 .

[0028] The waterproof cylinder 8 is made of high-strength waterproof plastic or composite material, and has good waterproof performance and corrosion resistance. A battery pack and a control module are arranged inside the waterproof cylinder 8, and the battery pack is electrically connected to the control module. The waterproof cylinder 8 adopts a sealed cylindrical cylinder structure design to ensure that the internal battery pack and electronic control components are completely isolated from water. The head of the waterproof cylinder 8 adopts a parabolic streamline design to reduce underwater resistance. The waterproof cylinder 8 also has good heat dissipation performance to prevent the performance of the system from being affected by excessive temperature during operation.

[0029] The battery pack is a 24V / 48V lithium battery pack. It has high energy density, long cycle life and good charge and discharge performance. The lithium battery protection board protects the battery from over-discharge, over-charge and over-current and has output short-circuit protection. The capacity of the battery pack is selected according to the range requirements of the water ski, and there is a power display screen and low-power sound alarm on the water ski.

[0030] It supports both fast charging and slow charging. Users can choose the appropriate charging method according to actual conditions. The charging port is waterproof to prevent water from entering during the use of the water ski.

[0031] The control module includes a main control board, which is connected to the battery pack and switch through a 24V / 48V to 5V voltage module, and is connected to the control button through a three-core watertight plug. The main control board is also connected to the propeller through electronic speed regulator 1 and electronic speed regulator 2 and a six-core watertight plug. A controller is set on the main control board. The controller uses a high-performance microcontroller and is responsible for receiving the operating instructions for the water ski control and controlling the speed and direction of the motor according to the instructions. The controller has functions such as overcurrent protection, overvoltage protection, and undervoltage protection. It has regional navigation electronic fence settings and control key return functions to ensure the safe operation of the system.

[0032] The water ski body 1 is made of high-strength lightweight material, and the angle between the seesaw 11 and the water ski body 1 is 15-25°. The angle between the seesaw 11 and the water ski body 1 with a larger angle is more inclined to maintain a smooth slide and master the balance, which is suitable for learning basic water skiing movements and improving the ability to control the water ski. The smaller tilt angle can reduce the resistance of the water and increase the sliding speed; when turning and performing tricks, it can provide greater flexibility and responsiveness, allowing the water skier to change direction and perform various movements more quickly. The 15-25° angle adopted by the present invention can provide a better operating experience for the water ski user under the premise of stability.

[0033] A forming process of a multi-control type electric water ski comprises the following steps: S1. Use mold forming technology to process high-strength lightweight materials into the required shape; during the manufacturing process, ensure that the surface of the board is smooth, free of bubbles and cracks to improve the buoyancy and strength of the board; S2. Assemble the motor, propeller and transmission device into a propeller according to the design requirements, and conduct commissioning and testing to ensure that the performance of the power system meets the requirements; S3. Integrate the battery pack and control module into a waterproof casing, connect and debug the lines, and consider the center of gravity balance for line layout and waterproofing.

[0034] The electric water ski control system uses a high-performance microcontroller, which is responsible for receiving the operating instructions of the water ski and controlling the speed and direction of the motor according to the instructions. The controller has functions such as overcurrent protection, overvoltage protection, and undervoltage protection to ensure the safe operation of the system. Regional traffic restrictions are controlled through GPS / BDS positioning and electronic map technology, with regional navigation electronic fence settings and control key return functions. The water ski operator sends instructions to the controller through the operating handle. The operating handle is installed in two ways: one is the water ski handle operation; the other is the standing pull rope operation. Both operation methods are simple, intuitive, easy to operate, and waterproof.

[0035] Install electronic components such as controllers, sensors and operating handles in a waterproof housing, and connect and debug the lines.

[0036] Its usage is as follows: Charging: Before use, connect the water ski to the charger to charge. After charging is complete, disconnect the charger.

[0037] Start: The user climbs on the water ski, holds the operating handle, presses the start button, the motor starts to run, and the propeller pushes the water ski forward.

[0038] Forward and backward: By operating the forward and backward buttons on the handle, you can control the forward and reverse rotation of the motor to move the water ski forward and backward.

[0039] Steering: Control the direction of the motor by operating the steering button on the handle to achieve the steering operation of the water ski.

[0040] Maintenance Regular inspection: Regularly check the various components of the water ski, including the board body, power system, control system and battery pack, to ensure their normal operation.

[0041] Cleaning and maintenance: After use, the surface and inside of the water ski should be cleaned in time to remove dirt and salt to prevent corrosion and damage.

[0042] Battery maintenance: Regularly charge and discharge the battery pack to extend its service life.
