Abstract
Description
I. Technical Field
[0001] This invention is specifically designed for the needs of amphibious users and is a fast and practical means of transportation. This amphibious electric motorcycle invention fills a gap in the domestic and international electric motorcycle market and belongs to the field of intelligent transportation. II. Background Technology
[0002] There have been many attempts at amphibious electric motorcycles, some using airbags, others foam boards, and still others plastic bottles, among others. Generally speaking, these worthwhile attempts all revolve around the study of buoyancy. However, success has been difficult to achieve. It's worth mentioning that a foreign company launched an amphibious motorcycle called "Gibbs-Biski," touted as the world's most advanced motorcycle. While the advantages of amphibious operation are undeniable, the disadvantages are also very obvious. Aside from the price and the environmental impact of fuel consumption, the motorcycle's width alone is nearly one meter, much wider than the handlebars, which is hard to accept. In China, amphibious electric motorcycles are currently rarely seen on the market. As we all know, isn't an amphibious electric motorcycle simply a combination of a motorcycle and a boat? Couldn't we just turn a motorcycle into a boat, or vice versa? Yes. Now the problem arises: according to the principles of mechanics, a car can carry a boat, but the boat must be small enough, otherwise the road will be impassable; similarly, a boat can carry a car, but the boat must have sufficient buoyancy to lift the car. These are the basic requirements for amphibious electric motorcycles. Therefore, is it possible to make a boat as wide as a car, and a car float on water like a boat? It turns out that this is feasible. This requires amphibious electric motorcycles to overcome two major technical challenges: first, solving the buoyancy problem for amphibious compatibility; and second, solving the resistance problem of the front and rear wheels when traveling on water. III. Summary of the Invention
[0003] The invention of the hovering amphibious electric motorcycle can be divided into four main parts:
[0004] (I) Floating box assembly (see...) Figure 1 ).
[0005] 1. The floating body frame is similar to a boat shape on the side and has a trapezoidal cross-section. It is about 20 cm wide at the top, 60 cm wide at the bottom, and about 40 cm high. The two sides are floating movable boxes, and the buoyancy space of the whole vehicle is H-shaped. Water propulsion devices are installed on both sides of the rear wheels. The overall length of the vehicle is about 220 cm and the width is about 65 cm.
[0006] 2. The entire vehicle is waterproofed. The entire electric vehicle (except for the front and rear wheels) is waterproofed. The left and right sides are floating and variable movement spaces. The height of the box is about 45 cm. When closed, the width of the vehicle is only 65 cm, and when opened, the width of the vehicle is about 120 cm.
[0007] 3. The side-mounted, suspended movable boxes have an overlapping, interlocking shape with the vehicle body, wider on the outside and narrower on the inside. When unfolded, the boxes provide sufficient buoyancy for the vehicle to float on the water. The suspended boxes are connected to the frame on both sides by three hinges and two electrically operated telescopic devices, ensuring the boxes are as sturdy and stable as a boat when unfolded (see...). Figure 4 ).
[0008] 4. Flexible material connection: The suspended box has a rigid structure, with the bottom width of both sides of the box being approximately 15 cm. The bottom cross-section is similar to a Z-shape. High-energy rubber material is used to connect the movable box to the vehicle body, achieving waterproofing, pressure resistance, and free extension (see...). Figure 5 ).
[0009] 5. The electric telescopic device controls the closure of the box. The two sides of the floating movable box are fixed by hinges on the top and rely on 4 electric telescopic rods to control the extension of the box. The extension range is about 30 cm. Water and land riding can be switched with one button. On land, the two sides of the box are closed, and it is an electric motorcycle. On water, the two sides of the box are opened, and it is an electric jet ski.
[0010] (II) Rod-type electric lifting assembly for front wheels (see...) Figure 2 ).
[0011] 1. Front Fork Telescopic Rods. Extend the telescopic rods of the shock absorbers on both sides of the front fork by approximately 30 cm, allowing the rods to move up and down like pistons within the sleeves. The top of the front fork telescopic rods connects to a drop plate. The drop plate has two downward-pointing rods that align with a double-hole mounting plate on the steering shaft. This creates a docking device between the two top rods of the front fork telescopic rods and the double-hole mounting plate, achieving effective control of the steering.
[0012] 2. Front fork sleeves. Two fixed sleeves are made at the upper and lower ends of the steering shaft sleeve at the front of the frame, corresponding to the front fork. The sleeves are fixed to two iron plates. The upper and lower ends of the iron plates are connected to the steering shaft through bearings, so that the front fork and the front axle form a misaligned connection. The front fork moves up and down inside the sleeve, forming a lever-type front wheel lifting device.
[0013] 3. Electric lifting device. An electric telescopic rod is used to control the raising and lowering of the front wheel at the middle position between the two plates on the upper part of the front fork. When the front wheel rises, the top sleeve of the telescopic rod leaves the steering shaft sleeve, locking the land direction and connecting the water direction control, thus entering the water mode; when the front wheel lowers, the top sleeve of the telescopic rod re-enters the steering shaft sleeve, disconnecting the water direction control, locking the water direction again, and entering the land mode.
[0014] (III) Track-type electric rear wheel lifting assembly (see...) Figure 1 ).
[0015] 1. Movable Shock Absorber. Bearings are installed at both ends of the shock absorber on the rear wheel. The lower part connects to the rear swingarm at an angle of approximately 50 degrees, and the upper part connects to a track-mounted electric telescopic device. The movable shock absorber is mainly used to solve the problem of rear wheel resistance when moving forward on water. It retracts on land and extends on water.
[0016] 2. Rail-mounted rear wheel lifting device. This electric lifting device is installed under the seat in the middle of the frame. When the telescopic link is pulled forward, the top of the shock absorber moves forward, thereby raising the rear wheel; when the telescopic link is pushed backward, the top of the shock absorber moves backward, thereby lowering the rear wheel. In this way, the rear wheel can be effectively switched between amphibious and land-based operation modes.
[0017] (iv) Concealed electric injection device (see) Figure 5 ).
[0018] Electric jets, approximately 80-100 mm in diameter and equipped with steering, are installed at the bottom of the boxes on both sides of the rear wheels, effectively solving the problem of power and directional control for forward movement on water. The electric jets utilize a water-land switch to achieve separate control on water and land. In water mode, the direction and speed of movement can be controlled, while in land mode, these controls are locked; similarly, in land mode, the direction and speed of movement can be controlled, while in water mode, these controls are locked. This electric jet is a concealed device; it is hidden from view on land by the retractable electric telescopic mechanism and is only visible when the telescopic mechanism is extended. This design protects the electric jet system and ensures safe operation on water.
[0019] The operating principle of the hovering amphibious electric motorcycle: A hovering, variable-sized sealed casing, a water propulsion system, and front and rear wheel lifting devices are installed on the electric motorcycle, allowing for rapid switching between land and water travel. On land, it is an electric motorcycle; on water, it is an electric jet ski. Riding on land is similar to riding a regular motorcycle, with minimal speed impact; the only difference is its dimensions. When moving in water, simply switch to water mode to move freely. Upon reaching the shore, exit water mode and re-enter land mode to disembark.
[0020] Installation of the hovering amphibious electric motorcycle: 1. Weld the electric motorcycle frame according to the specifications of the hovering box; 2. Install the electric lifting devices for the front and rear wheels; 3. Install the electric jets on both sides of the rear wheel; 4. Install the electric telescopic device for the hovering box; 5. Assemble the hovering box with the frame; 6. Install the amphibious operation mode switch, box closure switch, and front and rear wheel lifting switches on the electric motorcycle handlebars; 7. Integrate the newly added circuit with the electric motorcycle's wiring system; 8. Install the rubber of the flexible connections according to waterproof requirements. IV.

[0033] The embodiments of the present invention will be further described below with reference to the accompanying drawings:
[0034] In this embodiment, the specifications and performance of this amphibious electric motorcycle are described. Based on buoyancy calculations and relevant data from existing motorcycles and motorboats, we used a fully functional electric motorcycle as a sample for modification testing. The basic data is roughly as follows: body length approximately 2.2 meters, body width approximately 65 centimeters, extended body width approximately 120 centimeters, body box weight approximately 30 kilograms, motorcycle weight approximately 100 kilograms, weight of the electric jet, wheel lift, and battery approximately 30 kilograms, total vehicle weight approximately 160 kilograms, load capacity 300 kilograms, handlebar height approximately 0.96 meters, handlebar width approximately 0.71 meters, wheelbase approximately 1.60 meters, land speed approximately 60-80 MPH, water speed approximately 50-60 MPH.
[0035] This amphibious electric motorcycle has the following features:
[0036] 1. Maximizing ground clearance by using the bottom of the frame as the bottom of a boat to construct a movable box body, eliminating the support frame, resulting in strong off-road performance.
[0037] 2. To minimize air resistance, the floating box, similar to a ship's hull structure, has a streamlined shape when closed, in order to reduce resistance during land riding as much as possible (see...). Figure 5 ).
[0038] 3. The suspended movable box is connected to the vehicle body with high-energy rubber to achieve waterproof and pressure-resistant properties. The footrest recess forms a peninsula shape with the movable box to facilitate the extension and retraction of the box.
[0039] 4. The stability of the suspended movable box relative to the vehicle body is ensured by connecting the left and right sides to the frame via three hinges and two electric telescopic devices, guaranteeing the box's structural balance (see...). Figure 4 ).
[0040] 5. The front and rear wheel lifting devices effectively solve the resistance problem when traveling on water, allowing the amphibious motorcycle to travel faster on water and also solving the parking problem on land (see...). Figure 1 ).
[0041] 6. The concealed electric jet system employs dual drive, enabling water speeds similar to those of a motorboat. Water movement direction is controlled by the front wheel handle and synchronized with land-water transitions (see...). Figure 5 ).
[0042] 7. It has a large cargo space; the suspended enclosure has a large volume and can hold essential water sports items such as life jackets, paddles, repair tools, and various personal belongings (see...). Figure 3 ).
[0043] 8. Extended range: The cargo box has a volume large enough to accommodate a battery more than twice the size of a typical electric vehicle, thus significantly increasing the range and reducing travel worries (see...). Figure 3 ).
[0044] 9. The enclosure is sealed and waterproof, and a movable ventilation cover is installed under the seat for easy closure. The enclosure has a water immersion alarm device, and the entire enclosure is waterproof and pressure-resistant (see...). Figure 6 ).
[0045] This amphibious electric motorcycle is rationally designed, easy to use, and boasts an ultra-long battery life, making it suitable for all enthusiasts of amphibious sports. It's worth mentioning that this type of amphibious electric motorcycle has even greater practical significance for water rescue and flood relief. Amphibious electric motorcycles allow for safe and free travel on land and water without altering traditional riding methods, greatly facilitating people's travel, saving energy and reducing emissions, and benefiting the country and its people.
