The vision sensor 60 provided at the motor mount 40 connected to the first arm 20 and the vision sensor 60 provided at the top of the central body 10 constitute a first multi-view camera module. The vision sensor 60 provided at the motor mount 40 connected to the second horn 30 and the vision sensor 60 provided at the bottom of the central body 10 constitute a second multi-view camera module.

So, the environmental information of four rotor unmanned vehicles 100 tops can be surveyed to first many meshes module of making a video recording, the environmental information of four rotor unmanned vehicles 100 below can be surveyed to the many meshes module of making a video recording of second, first many meshes module of making a video recording and the many meshes module of making a video recording of second can acquire the environmental information around four rotor unmanned vehicles 100 more comprehensively, and the environmental information of making a video recording the module and detecting through first many meshes module and the many meshes module of making a video recording of second, can acquire flight attitude and barrier information of four rotor unmanned vehicles 100, be used for keeping away the barrier for four rotor unmanned vehicles 100, measure the speed, fix a position, navigation etc. provide information and data.

It is understood that in other embodiments, the central body 10 may be provided with a visual sensor 60 at the top or bottom, depending on the particular arrangement. For example, in the embodiment shown in fig. 4, the vision sensor 60 may be disposed at the bottom of the central body 10, so that the vision sensor 60 disposed at the motor mount 40 connecting the first boom 20 and the second boom 30 and the vision sensor 60 at the bottom of the central body 10 form a multi-view camera module when the quad-rotor unmanned aerial vehicle 100 is in the deployed state.

In some embodiments, the distance between the vision sensors 60 of the first multi-view camera module is adjusted by rotation of the first horn 20 relative to the hub 10. In some embodiments, the distance between the vision sensors 60 of the second multi-view camera module is adjusted by rotation of the second horn 30 relative to the central body 10. In some embodiments, the distance between the vision sensors 60 of the first multi-view camera module is adjusted by rotation of the first horn 20 relative to the central body 10, and the distance between the vision sensors 60 of the second multi-view camera module is adjusted by rotation of the second horn 30 relative to the central body 10.

So, can be through adjusting the distance between the visual sensor 60 of the first many orders of making a video recording module, and then can adjust the first many orders of making a video recording module and detect the object of different distances and scope, through adjusting the distance between the visual sensor 60 of the second many orders of making a video recording module, and then can adjust the second many orders of making a video recording module and detect the object of different distances and scope.

Generally, the connection between the centers of two different vision sensors 60 of the same multi-view camera module can be called as a base line, and different base line lengths are suitable for sensing target objects with different distances and ranges. And for a short-distance target object, the length of the base line can be appropriately shortened. The quad-rotor unmanned aerial vehicle 100 may further include an image processing unit (not shown) for processing images acquired by the vision sensors 60, and specifically, the image processing unit may be capable of combining images/videos acquired by the different vision sensors 60 into an image/video having depth information based on information such as a base length between the different vision sensors 60 and a distance of a target object. Preferably, the image processing unit may be provided on a control board inside the quad-rotor unmanned aerial vehicle 100.

Therefore, when the distance between the vision sensors 60 of the first multi-view camera module is larger, the first multi-view camera module can sense the object which is farther and has a larger range, and conversely, the first multi-view camera module can sense the object which is closer and has a smaller range. It can be understood that the larger the distance between the vision sensors 60 of the first multi-view camera module is, the more image information content the first multi-view camera module detects is. The distance between the vision sensors 60 of the first multi-view camera module can be adjusted by rotating the first arm 20 according to actual conditions to adjust the sensing range of the first multi-view camera module, so that the load of the image processing unit processing the information content sensed by the first multi-view camera module matches the actual conditions.

Similarly, in practical applications, when the distance between the vision sensors 60 of the second multi-view camera module is adjusted by rotating the second arm 30, the sensing range of the second multi-view camera module can be adjusted, so that the load condition of the image processing unit can be matched.

Referring to fig. 1 and 2 and 4, in some embodiments, the power assembly 50 includes a propeller 52 coupled to an output shaft of a motor 51. The propeller 52 and the vision sensor 60 are respectively positioned at two sides of the motor mounting seat 40 opposite to each other. In this way, the propeller 52 and the vision sensor 60 can operate independently of each other without interfering with each other, and the space of the motor mount 40 can be effectively used.

Specifically, when motor 51 is operated, propeller 52 is driven to rotate, providing flight power for quad-rotor unmanned aerial vehicle 100. When the propeller 52 rotates, a circular shielding area is formed, and the propeller 52 and the vision sensor 60 are respectively located on two opposite sides of the motor mounting base 40, so that when the propeller 52 rotates, the detection of a target object by the vision sensor 60 is not affected. Furthermore, the propellers 52 and the vision sensor 60 are disposed along the height direction of the quad-rotor unmanned aerial vehicle 100, so that the lateral space occupied by the quad-rotor unmanned aerial vehicle 100 can be reduced, and the quad-rotor unmanned aerial vehicle 100 can be more compact.

Referring to fig. 3, in some embodiments, when quad-rotor unmanned aerial vehicle 100 is in a folded position, the height of propeller 52 on first boom 20 is greater than the height of vision sensor 60 on top of hub 10; the propeller 52 at the second horn 30 is at a lower level than the vision sensor 60 at the bottom of the hub 10.

In this way, when quad-rotor unmanned aerial vehicle 100 is in the folded state, propeller 52 located in first arm 20 can protect vision sensor 60 located at the top of central body 10 from external friction or collision, propeller 52 located in second arm 30 can protect vision sensor 60 located at the bottom of central body 10 from external friction or collision, and vision sensors 60 located at the top and bottom of central body 10 can be prevented from being damaged when quad-rotor unmanned aerial vehicle 100 is carried or stowed.

Referring to fig. 3 and 6, in some embodiments, the propeller 52 is a foldable paddle. The foldable paddles are convenient to store, can be folded when the quad-rotor unmanned aerial vehicle 100 is in an idle non-working state (non-flight state), reduce the occupied space of the quad-rotor unmanned aerial vehicle 100, and the folded propellers 52 can also reduce the risks of being bent, broken and the like in the carrying and storing processes.

Further, when four rotor unmanned vehicles 100 is in fold condition, screw 52 also can be in fold condition, can further reduce four rotor unmanned vehicles 100's occupation space, is favorable to promoting four rotor unmanned vehicles 100 at the compactedness of fold condition, is convenient for four rotor unmanned vehicles 100 carry and accomodate.

The explanation and advantages of the first embodiment are mostly applicable to the third embodiment, and the main difference is that in the third embodiment, when the quad-rotor unmanned aerial vehicle 100 is in the deployed state, the vision sensor 60 detects the object light of a larger range and distance below the quad-rotor unmanned aerial vehicle 100, and can be applied to scenes in which the object below the quad-rotor unmanned aerial vehicle 100 is more interested and the field above the quad-rotor unmanned aerial vehicle is wider and flatter, such as the photograph of the lake or the flat ground. In fig. 4, a receiving groove 11 is formed on the peripheral side of the central body 10, and when the quad-rotor unmanned aerial vehicle 100 is in the folded state, the first arm 20 and the second arm 30 are at least partially received in the receiving groove 11, so that on the one hand, the lateral space occupied by the quad-rotor unmanned aerial vehicle 100 in the folded state can be further reduced, and on the other hand, the visual sensor 60 can be more thoroughly protected.

In the fourth embodiment, when the quadrotor unmanned aerial vehicle 100 is in the unfolded state, the visual sensor 60 provided in the motor mount 40 connected to the first arm 20 and the visual sensor 60 provided in the motor mount 40 connected to the second arm 30 are both directed upward, and when the quadrotor unmanned aerial vehicle 100 is in the folded state, the visual sensor 60 provided in the motor mount 40 connected to the first arm 20 and the visual sensor 60 provided in the motor mount 40 connected to the second arm 30 are both directed downward. The explanation and advantages of the first embodiment are more than partially applicable to the fourth embodiment, and the main difference is that in the fourth embodiment, when the quad-rotor unmanned aerial vehicle 100 is in the deployed state, the vision sensor 60 detects a larger range and distance of object light above the quad-rotor unmanned aerial vehicle 100, and can be applied to scenes where objects above the quad-rotor unmanned aerial vehicle 100 are more interesting and where the ground is wider and flatter, such as a photograph of the sky on a flat ground.

In the present embodiment, "upward" and "downward" may respectively refer to the up-down direction along the height of the quad-rotor unmanned aerial vehicle 100.

It will be appreciated that for other multi-rotor unmanned aerial vehicles, the orientation embodiments are not limited to the first, second, third and fourth orientation embodiments described above, and the orientation of the vision sensors may be configured according to design requirements. For example, for a five-rotor unmanned aerial vehicle, three first arms are provided at the front of the central body, two second arms are provided at the rear of the central body, the three vision sensors provided at the motor mounts connected to the first arms may be oriented in the same or different directions, and so on. Not to be taken as an example herein. Other multi-rotor unmanned vehicles may be two-rotor unmanned vehicles, three-rotor unmanned vehicles, five-rotor unmanned vehicles, six-rotor unmanned vehicles, or more-rotor unmanned vehicles, etc. In addition, the multi-rotor unmanned aerial vehicle can also include one or two or more arms connected at the center of the hub.

In the embodiment of the present invention, the first direction and the second direction have different embodiments from the arrangement of the yaw axis of the quad-rotor unmanned aerial vehicle 100, and the following description is given.

In one embodiment, referring to fig. 1 and 3, the first direction and the second direction are substantially parallel to the yaw axis of quad-rotor unmanned aerial vehicle 100.

As such, the occupied lateral space is relatively small when the quad-rotor drone 100 is in the deployed state, and the occupied longitudinal and lateral spaces are relatively small when the quad-rotor drone 100 is in the collapsed state.

Specifically, the yaw axis of quad-rotor unmanned aerial vehicle 100 is substantially parallel to the up-down direction, and motor mount 40 is typically attached to the distal ends of first and

second booms

20, 30. Referring to fig. 7, the first direction includes a direction c1, a direction c2, a direction c3 and a direction c4, and the direction c1, the direction c2, the direction c3 and the direction c4 are respectively inclined to form an included angle with respect to the yaw axis of the quad-rotor unmanned aerial vehicle 100, and the included angle may be (0 ° or 90 °).

The first direction is inclined with respect to the yaw axis of the quad-rotor unmanned aerial vehicle 100, so that the lateral distance between the motor mount 40 and the central body 10 is relatively small, and further, when the quad-rotor unmanned aerial vehicle 100 is in the unfolded state, the occupied lateral space is relatively small, and the quad-rotor unmanned aerial vehicle is relatively suitable for narrow application scenes.

Referring to fig. 6, the second direction is a direction b, the direction b is substantially parallel to the yaw axis of the quad-rotor unmanned aerial vehicle 100, and when the quad-rotor unmanned aerial vehicle 100 is in the folded state, the first boom 20 and the second boom 30 are substantially located in the peripheral side space in the thickness direction of the central body 10, so as to reduce the longitudinal and lateral spaces occupied by the quad-rotor unmanned aerial vehicle 100 in the folded state.

In fig. 4 and 6, the central body 10 has a receiving groove 11 formed on the peripheral side thereof, and the first arm 20 and the second arm 30 are at least partially received in the receiving groove 11 when the quad-rotor unmanned aerial vehicle 100 is in the folded state, so that the lateral space occupied by the quad-rotor unmanned aerial vehicle 100 in the folded state can be further reduced, and the visual sensor 60 can be more thoroughly protected.

It is to be appreciated that the roll axis of quad-rotor drone 100 is substantially parallel to the fore-aft direction of quad-rotor drone 100 and the pitch axis is substantially parallel to the left-right direction of quad-rotor drone 100.

Different joint embodiments may be tailored to the structural characteristics of different quad-rotor unmanned aerial vehicles 100.

In the first embodiment of the joint, referring to fig. 1 and 3, the first joint 21 and the second joint 31 are offset from each other along the height of the central body 10. In this embodiment, the height (thickness) of the central body 10 is larger, the central body has more space along the peripheral side of the height direction, and along the height direction of the central body 10, the first connecting portion 21 and the second connecting portion 31 are arranged in a staggered manner, so that the first boom 20 and the second boom 30 have longer lengths, and the flight of the quad-rotor unmanned aerial vehicle 100 can be more flexible under the condition that the vibration of the whole quad-rotor unmanned aerial vehicle 100 is ensured to meet the requirement.

In the second embodiment of the joint, referring to fig. 4 and 6, the first joint 21 and the second joint 31 are located at substantially the same height. In this embodiment, the height (thickness) of the central body 10 is small, the peripheral side of the central body 10 in the height direction has a small space, and the first connection 21 and the second connection 31 are located at substantially the same height in the height direction of the central body 10, so that the four-rotor unmanned aerial vehicle 100 is more compact and portable.

It is to be understood that the joint embodiment is not limited to the first joint embodiment and the second joint embodiment, and the positions of the first joint 21 and the second joint 31 may be configured according to design requirements.

In the present embodiment, when the quad-rotor unmanned aerial vehicle 100 is folded, the first arm 20 and the second arm 30 have different arm setting embodiments in the height direction of the central body 10, which will be described below.

In the first embodiment of arm arrangement, referring to fig. 3, when the quad-rotor unmanned aerial vehicle 100 is in the folded state, the first arm 20 and the second arm 30 are spaced apart from each other in the height direction of the central body 10. Thus, the first horn 20 and the second horn 30 can have longer lengths, and the flight of the quad-rotor unmanned aerial vehicle 100 can be more flexible under the condition that the vibration of the whole quad-rotor unmanned aerial vehicle 100 meets the requirement.

In the second embodiment of the arm arrangement, referring to fig. 7, when the quad-rotor unmanned aerial vehicle 100 is in the folded state, the first arm 20 and the second arm 30 are juxtaposed in the height direction of the central body 10. Thus, the height (thickness) of the central body 10 is small, and the peripheral side of the central body 10 in the height direction has a small space. Along the height direction of the central body 10, the first horn 20 and the second horn 30 are arranged in parallel, so that the whole four-rotor unmanned aerial vehicle 100 is more compact and more convenient to carry.

It is to be understood that the horn installation embodiment is not limited to the first and second horn installation embodiments, and the positions of the first and

second horns

20 and 30 may be configured according to design requirements.

In the embodiment of the present invention, when the four-rotor unmanned aerial vehicle 100 is switched between the deployed state and the folded state, the arms have different rotation embodiments, which will be described below.

In the first embodiment, the first arm 20 and the second arm 30 rotate in the same direction. Specifically, the first rotation embodiment may include two cases. In the first case, referring to fig. 1 to 3, when the folded state is switched from the unfolded state, the first arm 20 and the second arm 30 rotate clockwise, and when the folded state is switched from the folded state, the first arm 20 and the second arm 30 rotate counterclockwise. In the second case, the first arm 20 and the second arm 30 may be rotated in a counterclockwise direction when switching from the unfolded state to the folded state, and the first arm 20 and the second arm 30 may be rotated in a clockwise direction when switching from the folded state to the unfolded state. Thus, the first boom 20 and the second boom 30 do not interfere with each other during the unfolding and folding processes, and the first boom 20 and the second boom can have a longer length, so that the flight of the quad-rotor unmanned aerial vehicle 100 can be more flexible under the condition that the vibration of the whole quad-rotor unmanned aerial vehicle 100 is ensured to meet the requirement.

In the second rotation embodiment, the first arm 20 and the second arm 30 rotate in different directions. Specifically, the second embodiment of rotation may include two cases. In the first case, referring to fig. 4 and 6, when the folded state is switched from the unfolded state, the first arm 20 rotates counterclockwise, and the second arm 30 rotates clockwise, and when the folded state is switched from the folded state, the first arm 20 rotates clockwise, and the second arm 30 rotates counterclockwise. In the second case, when the folded state is switched from the unfolded state to the folded state, the first arm 20 rotates clockwise, and the second arm 30 rotates counterclockwise, and when the folded state is switched from the folded state to the unfolded state, the first arm 20 rotates counterclockwise, and the second arm 30 rotates clockwise.

In some embodiments, the first and

second arms

20, 30 are connected to the hub 10 by a pivot 70. The axis L of the pivot 70 is disposed at a predetermined angle to the roll axis of the quad-rotor unmanned aerial vehicle 100.

In this way, the extreme positions of the first and

second arms

20, 30 in the deployed state can be adjusted by setting a preset angle between the axis L of the pivot 70 and the roll axis of the quad-rotor unmanned aerial vehicle 100.

It can be understood that the first arm 20 rotates around the pivot 70 about the axis L of the pivot 70, the path swept by the first arm 20 is approximately a conical surface, and the axis L of the pivot 70 is the rotation axis of the conical surface.

Similarly, the second arm 30 rotates around the axis L of the pivot 70 about the pivot 70, and the path swept by the second arm 30 is approximately a conical surface, and the axis L of the pivot 70 is the rotation axis of the conical surface.

In the embodiment of the present invention, there is a first included angle between the axis of the pivot 70 connecting the first boom 20 and the roll of the quad-rotor unmanned aerial vehicle 100, and there is a second included angle between the axis of the pivot connecting the second boom 30 and the roll of the quad-rotor unmanned aerial vehicle 100, which have different angle embodiments, and the following description is given.

In a first angular embodiment, the first angle and the second angle are the same. Thus, when the quad-rotor unmanned aerial vehicle 100 is in the unfolded state and the folded state, the first boom 20 and the second boom 30 have certain symmetry, which is beneficial to improving the aesthetic feeling of the appearance of the quad-rotor unmanned aerial vehicle 100.

Specifically, the first included angle may include two included angles between the axis L of the pivot 70 connecting the two first arms 20 and the central body 10 and the roll axis, and the second included angle may include two included angles between the axis L of the pivot 70 connecting the two second arms 30 and the central body 10 and the roll axis, in the first embodiment, the two first included angles are equal, the two second included angles are equal, and the first included angle is equal to the second included angle. The quad-rotor unmanned aerial vehicle 100 of fig. 1-7 illustrates a first angular embodiment.

In a second angular embodiment, the first included angle and the second included angle are different. So, can be according to the actual demand, through the size that sets up first contained angle and second contained angle respectively, adjust the gesture of first horn 20 and second horn 30 at development condition and fold condition.

It is understood that the comparison between the first angle and the second angle refers to the comparison between the first angle and the second angle when the quad-rotor unmanned aerial vehicle 100 is in the same state, for example, when the quad-rotor unmanned aerial vehicle 100 is in the deployed state, the first angle and the second angle are the same or different.

In some embodiments, quad-rotor unmanned aerial vehicle 100 further includes a flight controller and an inertial measurement unit electrically connected to the flight controller for detecting an attitude of quad-rotor unmanned aerial vehicle 100 to allow the flight controller to control quad-rotor unmanned aerial vehicle 100 to fly according to the attitude.

As such, flight controller can monitor and control the flight attitude of quad-rotor unmanned aerial vehicle 100, enabling quad-rotor unmanned aerial vehicle 100 to fly safely.

Specifically, an Inertial Measurement Unit (IMU) may be disposed at the central body 10, and a damping unit may be disposed between the inertial measurement unit and the central body 10, and the damping unit may buffer or eliminate vibration from the central body 10 to the inertial measurement unit, so that information obtained by the inertial measurement unit is more accurate and reliable. In this embodiment, the damping unit may include a damping ball, which may be made of rubber, silicone, or the like.

Referring to fig. 1 and 4, in some embodiments, the motor mounting base 40 is provided with an indicator lamp 41. Thus, the indicator lamp 41 can remind the user or others of the position of the quadrotor unmanned aerial vehicle 100 in the night flight, and guarantee is provided for safe flight. Specifically, the indicator lamp 41 may include a light emitting diode. In addition, the indicator 41 may be provided in other positions, such as the top and/or bottom of the central body 10, etc., as desired.

Indicator light 41 can also regard as four rotor unmanned vehicles 100's status light, and indicator light 41 can show the light of multiple colour, and the light of different colours can show four rotor unmanned vehicles 100 different states, and in four rotor unmanned vehicles 100 flight, the user can observe four rotor unmanned vehicles 100's operating condition through indicator light 41. For example, a blue light may indicate normal operation, a yellow light may indicate low power, and a red light may indicate component failure.

The central body is provided with a cradle head. The plurality of arms are connected with the central body, and the plurality of arms are provided with motor mounting seats which are used for mounting power components of the multi-rotor unmanned aerial vehicle.
