AI Technical Summary

Benefits of technology

This new design allows for better performance on both types of flight without burning up any parts or causing damage due to high pressure levels from atmospheric conditions such as rain or snow. It also improves safety by reducing vibrations caused by turbulence and noise generated while navigating through rough waters compared to traditional designs where multiple separate motors are needed. Additionally, there's no heavier load placed upon the vehicle itself but instead only its own wheels. Overall, these technical features improve efficiency, mobility, stability, and ease of operation over existing systems.

Problems solved by technology

The technical problem addressed in this patented text relating to how to design an autopilot system for water or land vehicles (such as drones) without adding too much weight and complexity due to their high rotational speeds.

Embodiment 1

[0026] Such as figure 1 and figure 2 As shown, a power propulsion device suitable for sea and air amphibiousness includes a frame-type cage 5, a power motor 6 fixedly arranged in the middle of the cage 5, a propeller shaft 7 rotatably installed on the cage 5, and the power motor 6 power is transmitted to the transmission gear set 4 and the tilting motor 12 of the propeller shaft 7, one end of the propeller shaft 7 is connected with the propeller 1 for space through a one-way bearing, and the other end is fixedly provided with the propeller 9 for water, and the single The rotating mechanism is a one-way bearing, the bearing inner ring of the one-way bearing 3 is fixedly connected with the propeller shaft 7, and the bearing outer ring of the one-way bearing 3 is fixedly connected with the empty propeller 1, wherein the empty propeller 1 is The propeller made of nylon has a radius of 11 inches and a propeller angle of 45 degrees; the water propeller 9 is a fully immersed prope...

Embodiment 2

[0032] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the power motor 6 is a biaxial motor, and the two output shafts pass through the cage 5, and the empty propeller 1 is connected to one of the output shafts through a one-way rotation mechanism. Connected, the water propeller 9 is connected with another output shaft. A deep groove ball bearing 13 is arranged between the output shaft of the power motor 6 and the cage 5 . This embodiment has simple structure and reduces dead weight.

Embodiment 3

[0034] Such as Figure 3 to Figure 4 As shown, a multi-axis aircraft suitable for sea and air amphibious, including a fuselage 15, the fuselage is a waterproof cylindrical structure, can be suspended in water, two sides of the fuselage are respectively symmetrically provided with two parallel The connecting rod 14 also includes four power propulsion devices as described in the first embodiment, of course, the power propulsion device as described in the second embodiment can also be used as required. The free end of the connecting rod 14 is fixedly connected to the housing of the tilting motor 12 of the power propulsion device suitable for sea and air amphibiousness, and the four power propulsion devices are installed symmetrically, and the central axis distances of two adjacent propellers are equal.

[0035] The multi-rotor aircraft of this embodiment includes the flight work process of the air environment and the submerged work process of the underwater environment. in:

Abstract

The invention discloses an amphibious power propulsion device suitable for sea and air, comprising a frame type retainer, a tilting motor, a power motor fixedly arranged at the middle part of the retainer, as well as propellers for air and propellers for sea, which are coaxially and rotatably arranged at a certain interval, wherein the propellers for air are in driving connection with the power motor through a unidirectional rotation mechanism, the propellers for sea are in driving connection with the power motor, a rotating shaft of the tilting motor is fixed at the outer side of the retainer through a connecting plate, and the rotating axis of the tilting motor is perpendicular to the rotating axis of the propellers for air and the propellers for sea. The invention also provides an amphibious multi-axis aircraft suitable for sea and air. According to the amphibious power propulsion device and the amphibious multi-axis aircraft, the same motor is adopted to simultaneously adapt to two different working environments, namely in the air and under the water, thereby reducing the weight of the amphibious aircraft for sea and air and simplifying the structure of the aircraft; and meanwhile, the tilting motor is used for controlling the direction of power output, thereby increasing the maneuverability of the amphibious aircraft and strengthening the capability of the amphibious aircraft for finishing complex tasks.
