Description

TECHNICAL FIELD

[0001] The utility model relates to the field of unmanned plane, more particularly, relate to a kind of unmanned plane with multiple antennas. BACKGROUND

[0002] The unmanned plane antenna is installed on unmanned plane for receiving and transmitting radio waves, mainly responsible for receiving the signal of ground control station or satellite, and the state information, image data etc. of unmanned plane are returned to control center. The setting of unmanned plane antenna is crucial to ensure the communication quality, stability and overall performance of unmanned plane, not only related to the communication quality and stability of unmanned plane, also relates to the safety and functionality of unmanned plane. The existing unmanned plane is usually provided with only one antenna, and the antenna is arranged on the fuselage, but in the case of strong wind or electromagnetic interference, single antenna design can not effectively guarantee the stable transmission of signal, increase the risk of flight out of control, in addition, the antenna is too close to the fuselage, the fuselage will cause the antenna to be shielded, and the electronic components in the fuselage will also interfere with the antenna, thereby affecting the strength and stability of antenna signal. SUMMARY

[0003] The utility model aims at overcoming the defects of the prior art, provide a kind of unmanned plane with multiple antennas, to solve the defect that the single antenna design of existing unmanned plane can not effectively guarantee the stable transmission of signal, and antenna is too close to the fuselage, the fuselage will cause the antenna to be shielded, and the electronic components in the fuselage will also interfere with the antenna, thereby affecting the strength and stability of antenna signal.

[0004] The utility model takes the technical scheme, a kind of unmanned plane with multiple antennas, including fuselage, multiple rotor assemblies, foot stool and holder assembly, control module and battery are arranged in the fuselage;The multiple rotor assemblies are respectively arranged in the both sides of fuselage;The foot stool and holder assembly are arranged below the fuselage;Further include antenna, the antenna at least has two, is respectively arranged in the distal end of different rotor assemblies.

[0005] Setting at least two antennas can increase the strength of signal, improve the communication quality and reliability of unmanned plane in different environments. At least two antennas are respectively arranged on different rotor assemblies, the distance between antennas is increased, to avoid mutual interference. The antenna is arranged at the distal end of rotor assembly, can reduce the shielding of fuselage to antenna, also can reduce the interference of electronic components in fuselage to antenna, simultaneously, antenna is arranged on rotor assembly, can more conveniently carry out routine maintenance and replacement work. When needing to maintain or replace antenna, only need to simply disassemble relevant parts on rotor assembly, without needing to disassemble unmanned plane as a whole, greatly simplify maintenance process, shorten maintenance time.

[0006] Further, the antenna is vertically arranged on the rotor assembly.

[0007] When the antenna of the UAV is in a vertical state, especially at a high flight altitude or a long distance, this placement helps better receive the signal from the remote controller. This is because the vertical antenna can more effectively capture the electromagnetic waves from the remote controller, thereby reducing signal attenuation and interference.

[0008] Further, the antenna is arranged below the rotor assembly.

[0009] Arranging the antenna below the rotor assembly can reduce the interference of the rotor with the antenna signal during movement, thereby improving the stability and reception quality of the signal. In addition, arranging the antenna below the rotor assembly does not increase the height of the UAV, as the rotor assembly is arranged on the upper part of the fuselage.

[0010] Further, the antenna has two, respectively arranged on the two rotor assemblies in front of the fuselage.

[0011] Arranging the antenna on the two rotor assemblies in front of the fuselage can ensure the balance of the left and right sides of the UAV. Moreover, the horizontal height of the two rotor assemblies in front of the fuselage is higher than that of the two rotor assemblies at the back of the fuselage. Arranging the antenna on the two rotor assemblies in front of the fuselage, the bottom of the antenna will be higher than the feet of the UAV, thereby ensuring that the antenna will not be damaged when the UAV lands.

[0012] Further, the side of the antenna away from the rotor assembly is an arc surface.

[0013] The design of the arc surface helps to optimize the electromagnetic field distribution of the antenna. Arranging the side of the antenna away from the rotor assembly as an arc surface can make the antenna obtain better resonance effect at a certain frequency, thereby improving the reception and transmission efficiency of the signal. In addition, the design of the arc surface helps to reduce the air resistance encountered by the UAV during flight, thereby improving the endurance and flight efficiency of the UAV, while also reducing the impact and vibration of the antenna from the external environment.

[0014] Further, the fuselage is further provided with a front obstacle avoidance lens and a rear obstacle avoidance lens, and the front obstacle avoidance lens and the rear obstacle avoidance lens are both arranged upwardly inclined.

[0015] Arranging the obstacle avoidance lens upwardly inclined is mainly to enhance the sensing ability of the UAV in the vertical direction, so that the UAV can more accurately detect the obstacles above, thereby making timely avoidance actions. By inclining the obstacle avoidance lens upwardly, the UAV can cover a wider field of view, reducing the existence of visual blind area. The design of the upwardly inclined obstacle avoidance lens also helps to improve the flight safety of the UAV, especially when flying at low altitude or passing through areas with dense buildings. This design can effectively reduce the risk of collision and protect the UAV and the equipment carried by it.

[0016] Further, the upward angle of the front obstacle-avoiding lens with respect to the horizontal line is less than the upward angle of the rear obstacle-avoiding lens with respect to the horizontal line.

[0017] The front obstacle-avoiding lens mainly focuses on early warning and avoidance of direct obstacles in the flight direction, ensuring the smoothness of the flight route. A smaller upward tilt angle can more accurately monitor this direction. When flying forward, the unmanned aerial vehicle mainly focuses on obstacles in front, such as buildings and trees. In order to more accurately detect obstacles in the front near range, the upward tilt angle of the front obstacle-avoiding lens does not need to be too large, so as to focus on the area directly in front of the flight path and slightly above. The rear obstacle-avoiding lens is more of a supplementary protection, and in special cases such as backward flight, sudden turning, and rear monitoring, a larger upward tilt angle can expand the field of view and increase the monitoring range behind, providing more comprehensive protection.

[0018] Further, the upward angle a of the front obstacle-avoiding lens with respect to the horizontal line is 5-30 degrees.

[0019] The front obstacle-avoiding lens is more for detecting obstacles that will be encountered on the flight route, such as oncoming peaks and power poles. A smaller upward tilt angle helps to concentrate on detecting objects in a direction close to parallel to the flight plane. If the upward angle of the front obstacle-avoiding lens with respect to the horizontal line is greater than 30 degrees, it is not conducive to detecting objects directly in front of the flight plane. When the unmanned aerial vehicle is flying normally, the fuselage is slightly forward inclined. If the upward angle of the front obstacle-avoiding lens with respect to the horizontal line is less than 5 degrees, the front obstacle-avoiding lens may be horizontal downward when the unmanned aerial vehicle is flying.

[0020] Further, the upward angle a1 of the rear obstacle-avoiding lens with respect to the horizontal line is 30-60 degrees.

[0021] The unmanned aerial vehicle retreats at a relatively slow speed or rarely performs long-time backward flight operation, so the rear obstacle-avoiding lens can be set to a larger upward tilt angle to cope with occasional backward flight or comprehensive monitoring of the surrounding environment. The rear obstacle-avoiding lens has a larger upward tilt angle because it needs to consider the possible backward flight of the unmanned aerial vehicle or the sudden approach of high objects behind, and needs a larger upward field of view to ensure the safety behind. If the upward angle of the rear obstacle-avoiding lens with respect to the horizontal line is less than 30 degrees, it is not conducive to detecting the height of high objects behind; if the upward angle of the rear obstacle-avoiding lens with respect to the horizontal line is greater than 60 degrees, it is not conducive to detecting the horizontal distance between the unmanned aerial vehicle and the objects behind.

[0022] Further, the fuselage comprises an outer shell, an upper cover and a bottom cover, the upper cover is arranged above the outer shell, and the bottom cover is arranged below the outer shell; the obstacle-avoiding lens and the control module are arranged between the outer shell and the upper cover, and the battery is arranged between the bottom cover and the outer shell.

[0023] The shell divides the fuselage into two layers, the upper layer space is formed between the shell and the upper cover, the lower layer space is formed between the shell and the bottom cover, the obstacle avoidance lens, the control module and other components are arranged in the upper layer space, and the battery is arranged in the lower layer space, the battery generates heat in the charging and discharging process, the battery and the electronic components are divided into two layers, the battery overheating can be effectively prevented from damaging the surrounding electronic components, and the service life of the unmanned aerial vehicle is prolonged, in addition, the design that the battery and the electronic components are separated can provide independent heat dissipation paths for each component, the optimal working temperature of each component can be maintained, and therefore the overall stability of the system is improved, and meanwhile, the layered design makes the battery replacement more convenient.

[0024] Compared with the prior art, the unmanned aerial vehicle has the beneficial effects that: at least two antennas are arranged to increase the signal strength and improve the communication quality and reliability of the unmanned aerial vehicle in different environments; the at least two antennas are arranged at the distal ends of different rotor assemblies, the distance between the antennas and the distance between the antennas and the fuselage are increased, mutual interference between the antennas is avoided, and interference of electronic components in the fuselage on the antennas is avoided; the antennas are arranged on the rotor assemblies, so that daily maintenance and replacement work can be more conveniently performed; when the antennas need to be maintained or replaced, only the related parts on the rotor assemblies need to be simply disassembled, and the unmanned aerial vehicle does not need to be disassembled as a whole, so that the maintenance process is greatly simplified, and the maintenance time is shortened; the antennas are arranged vertically, so that the magnetic waves from the remote controller can be more effectively captured, and signal attenuation and interference are reduced; the obstacle avoidance lens is upwardly inclined, so that the sensing capability of the unmanned aerial vehicle in the vertical direction is enhanced, the unmanned aerial vehicle covers a wider visual range, the existence of a visual blind area is reduced, the flight safety of the unmanned aerial vehicle is improved, and the collision risk is reduced; the upward angle of the front obstacle avoidance lens relative to the horizontal line is 5-30 degrees, so that the front obstacle avoidance lens focuses on the area in front of the flight path and slightly above the flight path, and the front obstacle avoidance lens can more accurately detect obstacles in a relatively close range in front; and the upward angle of the rear obstacle avoidance lens relative to the horizontal line is 30-60 degrees, so that the rear obstacle avoidance lens plays a supplementary protection role, the monitoring range at the rear of the unmanned aerial vehicle is increased, more comprehensive protection is provided, and the unmanned aerial vehicle is prevented from colliding with obstacles at the rear in special situations such as backward flight and sudden turning.
