Description

Many rotor unmanned aerial vehicle's battery fixing device

Technical Field

The utility model relates to an unmanned aerial vehicle accessories field, in particular to many rotor unmanned aerial vehicle's battery fixing device.

Background

Present many rotor unmanned aerial vehicle can set up fuselage and battery separation in order to simplify structural design sometimes. When the unmanned aerial vehicle needs to be used, the battery and the body are connected in a matching manner; when no unmanned aerial vehicle is needed, the battery is detached and placed.

When the battery is mounted, the battery is usually fixed by bonding or binding with a special adhesive. In the process of bonding or binding, more materials and time are consumed, the fixing effect is not ideal, batteries fall off due to vibration of a machine body or unstable airflow in the flying process, and the flying stability is influenced and certain danger is generated.

Therefore, in order to solve the above problems, it is a common practice in the industry to place the battery in the central shell structure of the fuselage, but this requires a large space in the shell to place the battery, which wastes materials and increases the volume of the fuselage, and brings burden to the flight of the unmanned aerial vehicle.

And many rotor unmanned aerial vehicle's rotor arm adopts hollow structure usually in the design process, can lighten unmanned aerial vehicle's weight and conveniently walk the line in its inside again, the motor of connection control system and rotor support. In order to help the flight, the rotor arms of some multi-rotor unmanned aerial vehicles are designed into a streamline structure, the area of the bottom end port of the multi-rotor unmanned aerial vehicle is large, enough space is arranged in the thick rotor arms for accommodating an unmanned aerial vehicle battery, and the space is not fully utilized at present.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of installing the battery in many rotor unmanned aerial vehicle, the utility model discloses a many rotor unmanned aerial vehicle's battery fixing device, including rotor arm and battery fixation clamp, the rotor arm includes first body and second body, the diameter of first body is greater than the diameter of second body, and the one end of first body and second body is with toper transitional coupling, the battery fixation clamp is disc structure, the battery fixation clamp intermediate position is equipped with the opening that matches with the battery appearance, battery fixation clamp and first body inner wall fixed connection.

As a further improvement of the technical scheme, a plurality of wiring holes are formed in the battery fixing clamp.

As a further improvement of the above technical solution, the battery fixing clip is a lightweight plastic fixing clip.

As a further improvement of the above technical solution, the rotor arm is a carbon fiber tube.

As a further improvement of the above technical solution, the inner diameter of the second tube is smaller than the width of the battery.

The utility model has the advantages that:

through the utility model discloses a battery is installed to battery fixing device, can conveniently dismantle fast, and the inner space of rational utilization rotor arm again has avoided arranging great space in the fuselage casing and has laid the battery, has saved fuselage shell material, has reduced unmanned aerial vehicle's cost, has reduced unmanned aerial vehicle's volume and weight to the battery is difficult for droing, helps unmanned aerial vehicle's safe flight.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

As shown in fig. 1-3, the battery fixing device of the multi-rotor unmanned aerial vehicle of the present embodiment includes a rotor arm 1 and a battery fixing clip 2, and a battery 3 is disposed in the rotor arm 1 through the battery fixing clip 2.

The rotor arm 1 includes a first tube 11 and a second tube 12, the diameter of the first tube 11 is larger than the diameter of the second tube 12, the first tube 11 is in transition connection with the second tube 12, and the inner diameter of the second tube 12 is smaller than the width of the battery 3, so as to prevent the battery 3 from slipping into the second tube 12.
