The specific structure of the land-air dual-purpose unmanned aerial vehicle according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 2.

The land-air dual-purpose unmanned aerial vehicle of the present invention includes a fuselage 1, an arm group 2, a flight assembly 3 and a walking assembly 4. There are two arm assemblies 2 and the two arm assemblies 2 are arranged opposite to the fuselage 1. On the two side walls, each arm set 2 includes a plurality of arms 21, each arm 21 is rotatably arranged on the fuselage 1, and the flight assembly 3 is arranged on the end of the arm 21 away from the fuselage 1. The flight assembly 3 is configured to drive the fuselage 1 to fly, the walking assembly 4 is provided at an end of the arm 21 away from the fuselage 1, and the walking assembly 4 is configured to drive the fuselage 1 to travel. The land-air dual-purpose UAV has a flying form and a walking form. In the flying form, a plurality of arms 21 are arranged horizontally, and in a walking form, the plurality of arms 21 have an angle with the horizontal plane.

It is understandable that, in the present invention, the flight assembly 3 and the walking assembly 4 are both arranged on the end of the arm 21 away from the fuselage 1, which simplifies the structure of the entire land-air dual-purpose drone to a certain extent. Compared with the existing land-air dual-purpose unmanned aerial vehicle, the land-air dual-purpose unmanned aerial vehicle of the present invention has a smaller mass, thereby prolonging the endurance time of the land-air dual-purpose unmanned aerial vehicle of the present invention.

At the same time, due to the walking mode, the multiple arms 21 have an angle with the horizontal plane, that is to say, in the walking mode, the fuselage 1 has a certain distance from the ground, which makes the land-air dual-purpose drone in the walking mode It can easily traverse small obstacles on the ground and traverse obstacles of low height. As a result, the land-air dual-purpose drone of the present invention can better adapt to road conditions with many obstacles, thereby expanding the scope of application of the land-air dual-purpose drone and improving user satisfaction.

For the land-air dual-purpose UAV of the present invention, since the flight assembly 3 and the walking assembly 4 are both arranged on the end of the arm 21 away from the fuselage 1, the structure of the land-air dual-purpose UAV is simplified, and the land-air dual-use With the weight of the drone, the endurance of the land-air dual-purpose drone is extended. In addition, since in the walking mode, the multiple arms 21 have an angle with the horizontal plane, so that there is a certain distance between the body 1 in the walking mode and the ground, so that the land-air dual-purpose drone can easily overcome small obstacles on the ground. Objects and crossing obstacles with a low height, so that the land-air dual-purpose UAV can better adapt to road conditions with more obstacles, and expand the scope of application of the land-air dual-purpose UAV.

In some embodiments, the flight assembly 3 includes a flight motor and a propeller, the flight motor is arranged on the upper side of the end of the arm 21 away from the fuselage 1, and the propeller is connected to the motor shaft of the flight motor. As a result, the structure of the flight assembly 3 is very simple, thereby further reducing the weight of the entire land-air dual-purpose UAV, thereby prolonging the endurance time of the land-air dual-purpose UAV.

In some specific embodiments, the flying motor is a brushless motor. It is understandable that the brushless motor has less abrasion and less operating noise. The use of a brushless motor for the flight motor can extend the service life of the flight component 3 and reduce the flight noise of the entire land-air dual-purpose UAV, thereby improving user satisfaction. Of course, in other embodiments of the present invention, the flying motors can also be other types of motors, that is, the types of flying motors are not limited to brushless motors, but can be selected according to actual needs.

In some embodiments, the walking assembly 4 includes a walking motor and a walking wheel. The walking motor is provided on the lower side of the end of the arm 21 away from the fuselage 1, and the walking wheel is connected to the motor shaft of the walking motor. Therefore, the structure of the walking assembly 4 is very simple, thereby further reducing the weight of the entire land-air dual-purpose UAV, thereby prolonging the endurance time of the Lulong dual-purpose UAV.

In some specific embodiments, the walking motor is a brushless motor. It is understandable that the brushless motor has less abrasion and less operating noise. The use of a brushless motor for the walking motor can prolong the service life of the walking component 4, and can also reduce the walking noise of the entire land-air dual-purpose drone, thereby improving user satisfaction. Of course, in other embodiments of the present invention, the walking motor can also be other types of motors, that is to say, the type of walking motor is not limited to brushless motors, but can be selected according to actual needs.

In some embodiments, the land-air dual-purpose drone further includes a lock assembly (not shown in the figure), the lock assembly is arranged between the arm 21 and the fuselage 1, and the lock assembly has a locked state and a released state. In the locked state, the locking assembly locks the arm 21 on the fuselage 1, so that the arm 21 is fixed relative to the fuselage 1. In the released state, the locking assembly releases the arm 21 to make the arm 21 Can be rotated relative to the body 1. It is understandable that the existence of the locking component ensures the stability of the arm 21 in the flight and walking modes, and avoids the rotation of the arm 21 in the flight and walking modes, which may cause the unmanned aerial vehicle to move. The phenomenon of stability occurs.

In some embodiments, the locking component is a steering gear. It can be understood that the use of the steering gear as the locking component can better realize the switching back and forth of the locking component between the locked state and the released state. For example, a switch is added to the control panel of a land-air dual-purpose drone. When the user triggers the switch, the lock assembly can be switched between the locked state and the released state. This facilitates user operations and improves user satisfaction.

In some embodiments, each arm group 2 includes two arms 21, and the two arms 21 are spaced apart along the length of the fuselage 1. As a result, the flight and walking stability of the land-air dual-purpose UAV can be ensured, and the user's satisfaction degree is improved. Of course, in other embodiments of the present invention, the number of arms 21 included in each arm group 2 and the distribution manner of the plurality of arms 21 can be selected according to actual conditions, and are not limited to the above manner.

In some embodiments, in the walking configuration, the angle between the arm 21 and the horizontal plane is 45°-90°. It is understandable that too small an angle between the arm 21 and the horizontal plane will cause the fuselage 1 to be closer to the ground, thereby reducing the obstacle avoidance function of the land-air dual-purpose UAV. However, if the angle between the arm 21 and the horizontal plane is too large, the two arms 21 located on the opposite sides of the fuselage 1 will be closer together, which will also reduce the obstacle avoidance function of the land-air dual-purpose UAV. The angle between the arm 21 and the horizontal plane is controlled between 45° and 90°, which can not only ensure the distance between the fuselage 1 and the ground, but also ensure the distance between the two arms 21 on the opposite sides of the fuselage 1. It is far away, which better guarantees the obstacle avoidance function of the land-air dual-purpose UAV. Of course, in other embodiments of the present invention, in the walking mode, the angle between the arm 21 and the horizontal plane is not limited to 45-90°, and the angle between the arm 21 and the horizontal plane can be selected according to actual needs.
