Referring to fig. 1 and 2, a barometer assembly 10 according to an embodiment of the invention is used for a drone 100.
Referring to fig. 1-4, the drone 100 includes a central frame 20, a boom 30 extending outward from the central frame 20, a power assembly 40 disposed on the boom 30, and a housing 50 disposed on a lower side of the central frame 20, wherein the housing 50 forms a receiving cavity 52, and the receiving cavity 52 forms a through hole 512 located on a bottom surface 51 of the housing 50 and communicating the receiving cavity 52 with the outside.
The barometer assembly 10 includes at least one barometer 12 disposed in the receiving cavity 52.
In the barometer assembly 10 according to the embodiment of the invention, the barometer 12 is disposed in the accommodating cavity 52, the accommodating cavity 52 is communicated with the outside through the through hole 512, and the through hole 512 is disposed at a position furthest away from the power assembly 40, so as to improve the detection accuracy of the barometer assembly 10, and in addition, the through hole 512 is shielded by the housing 50, so that the influence of the airflow generated by the power assembly 40 on the barometer 12 disposed in the accommodating cavity 52 can be further reduced.
It will be appreciated that the power assembly 40 drives the drone 100 in motion by entraining nearby airflow that would result in nearby air pressure changes. The power assembly 40 and the housing 50 are respectively located on two opposite sides of the center frame 20, and the through holes 512 formed at the bottom of the housing 50 are spaced from the power assembly 40, so as to effectively reduce the influence of the air flow generated by the power assembly 40 on the air pressure near the bottom of the housing 50, and further reduce the influence on the barometer 12 in the accommodating cavity 52.
Specifically, the barometer assembly 10 may include one barometer 12, and may also include a plurality of barometers 12. When there are a plurality of barometers 12, it is helpful to reduce the accidental error of data, further improving the detection accuracy of the barometer assembly 10. For example, when the number of the barometers 12 is four, the data measured by the four barometers 12 are all transmitted to the flight controller of the drone 100, and the flight controller performs fusion processing on the data, specifically, averaging may be performed, or averaging may be performed after removing abnormal values. On the other hand, multiple barometers 12 are provided for redundant design considerations, e.g., when one of the barometers 12 fails, the other barometers 12 may operate properly so that the barometer assembly 10 may still detect a more appropriate air pressure value.
Referring to fig. 1 and 4, in some embodiments, power assembly 40 includes a motor 42 and a rotor 44, rotor 44 is coupled to motor 42, motor 42 drives rotor 44 to rotate, and rotation axis H of rotor 44 is substantially perpendicular to bottom surface 51 of housing 50. By substantially perpendicular, it is meant that the rotation axis H is not completely perpendicular to the bottom surface 51 of the housing 50, but the angle formed between the two is substantially close to 90 °, and the intersection point of the four rotation axes H is located above the drone 100, so that the rotation plane of each rotor 44 is slightly inclined downward from the end of the boom 30 toward the center frame 20, so that the airflow generated by the rotation of each rotor 44 is slightly inclined outward rather than vertically downward, and the radiation area of the airflow generated by the rotation of the four rotors 44 under the center frame 20 is wider, thereby increasing the stability of the flight of the drone 10.
Like this, motor 42 drives the rotation of rotor 44 and provides power for unmanned aerial vehicle 100, when rotor 44 is rotatory, the air velocity near rotor 44 is fast, form the negative pressure, the pivot H of rotor 44 is basically perpendicular to the bottom surface 51 of casing 50, make the bottom surface 51 of casing 50 keep away from rotor 44 to the greatest extent, the atmospheric pressure near the bottom surface 51 of casing 50 is basically not influenced by rotor 44 is rotatory, because accommodate chamber 52 and outside air intercommunication through the through-hole 512 that sets up in the bottom of casing 50 again, make the influence of the air current that rotor 44 produced to barometer 12 that sets up in accommodating chamber 52 less.
Referring to fig. 1 and 2, in some embodiments, the housing 50 further includes a battery compartment 53.
So, casing 50 sets up in centre frame 20 downside, and in battery compartment 53 was arranged in to the battery, because the battery dead weight is great, can reduce unmanned aerial vehicle 100's focus, helps making unmanned aerial vehicle 100 flight more steady.
Referring to fig. 2 and 4, in some embodiments, the housing 50 includes:
a vertically disposed middle partition 542;
a front cover mounting plate 544 provided on the front side of the middle partition 542;
a bottom cover mounting plate 546 provided at the bottom end of the middle partition 542,
a front cover 55 provided on the front cover mounting plate 544; and
a bottom cover 56 disposed on the bottom cover mounting plate 546, the bottom cover 56 including the bottom surface 51 of the housing 50;
the receiving cavities 52 are formed between the bottom cover 56 and the bottom cover mounting plate 546 or between the bottom cover 56 and the bottom cover mounting plate 546 and between the front cover 55 and the front cover mounting plate 544.
In this way, the housing cavity 52 communicates with the outside air through the through hole 512 of the bottom cover 56, and the barometer 12 may be disposed between the bottom cover 56 and the bottom cover mounting plate 546, or at least one barometer 12 may be disposed between the bottom cover 56 and the bottom cover mounting plate 546 and between the front cover 55 and the front cover mounting plate 544, and the barometer 12 is less affected by the airflow generated by the rotor 44.
Specifically, the receiving cavity 52 includes a first sub-cavity 522 formed between the bottom cover 56 and the bottom cover mounting plate 546 and a second sub-cavity 524 disposed between the front cover 55 and the front cover mounting plate 544. The first sub-chamber 522 and the second sub-chamber 524 are in communication, and at least one barometer 12 may be provided only in the first sub-chamber 522, at least one barometer 12 may be provided only in the second sub-chamber 524, and at least one barometer 12 may be provided in each of the first sub-chamber 522 and the second sub-chamber 524.
Of course, in other embodiments, the first sub-chamber 522 and the second sub-chamber 524 may not be connected, and at this time, at least one barometer 12 is disposed only in the first sub-chamber 522.
In some embodiments, the number of battery compartments 53 is two on either side of the middle partition 542.
So, two battery compartment 53 make unmanned aerial vehicle 100 can carry on two batteries simultaneously, help prolonging unmanned aerial vehicle 100's time of endurance, promote user experience. Two battery compartment 53 are located the both sides of median septum 542 respectively and make the focus of casing 50 be close the geometric centre of casing 50, help improving unmanned aerial vehicle 100's flight stability. The two batteries are arranged at intervals, so that the heat conduction effect between the two batteries can be reduced, and the battery temperature can be prevented from being overhigh.
In certain embodiments, the drone 100 includes a battery management system 60 disposed between the front cover mounting plate 544 and the front cover 55;
the front cover 55 is sealingly connected to the front cover mounting plate 544 and the center frame 20.
In this manner, the sealed connection of the front cover 55 to the front cover mounting plate 544 and the center frame 20 protects the battery management system 60 from the airflow generated by the power assembly 40, which helps to protect the battery management system 60. Further, the housing chamber 52 formed between the front cover mounting plate 544 and the front cover 55 communicates with the outside atmosphere only through the through hole 512, and the influence of the airflow generated by the power unit 40 on the barometer 12 provided in the housing chamber 52 is reduced.
Specifically, the battery management system 60 may be used to monitor the state of the battery or to manage the charging and discharging of the battery. For example, the battery management system 60 may obtain and manage parameters such as voltage, current, and temperature of the battery.
