Step S110: determining whether the intelligent device satisfies state switching conditions.
In the example of the present disclosure, the intelligent device maybe applied to a variety of application scenarios. In order to meet different application scenarios, the intelligent device may implement state switching. For example, when the intelligent device is shooting in flight, it is switched to a flight shooting state; when the intelligent device is shooting on the ground, it is switched to a ground shooting state; and when the intelligent device is used as a monitoring device, it is switched to a monitoring state.
When the intelligent device performs state switching, aground control terminal may send to the intelligent device a state switching instruction for instructing the intelligent device to switch from a current state to a target state, and after the intelligent device receives the state switching instruction, it may be determined that the intelligent device satisfies the state switching conditions. Alternatively, because the change of state may cause the data as is detected by the intelligent device per se to be different, the intelligent device may also self-detect whether the state switching conditions are met. For example, when the intelligent device detects that the current state is ground shooting, this indicates that the state switching conditions are met at this time, and then the intelligent device may be automatically switched to the ground shooting state; or when the intelligent device detects that the current state is flight shooting, this indicates that the state switching conditions are met at this time, and then the intelligent device may be automatically switched to the flight shooting state.
When the state switching conditions are met, step S120 is performed.
Step S120: switching the intelligent device from a first state to a second state.
When the intelligent device satisfies the state switching conditions, the intelligent device may be switched from the first state to the second state, so that the intelligent device may operate in the second state, thereby enabling the intelligent device to be switched to a state required by one of diverse application scenarios to allow the intelligent device to be applicable to a variety of application scenarios.
As an example, the state parameter of the intelligent device varies with the state, i.e., the switching of the intelligent device from the first state to the second state may be the switching of the state parameters, to be more specific, a first state parameter of the intelligent device in the first state is switched to a state parameter of the same in the second state at the time of controlling the intelligent device to switch from the first state to the second state.
Among them, the following several embodiments exist in the switching between the state parameters:
Embodiment I: a first bandwidth of an image transmission module of the intelligent device in the first state is switched to a second bandwidth in the second state.
Among them, the image transmission module is used by the intelligent device to transmit images to the ground control terminal. The image transmission module may be a wireless-fidelity (WiFi) image transmission module, a 5.8G wireless image transmission module, etc.
In order to implement the application of the image transmission module in various states, the bandwidth of the image transmission module may vary with the state. For example, when a distance between the intelligent device and the ground control terminal is close, then the intelligent device is in the first state, and the bandwidth of the image transmission module may be relatively higher, so that the image transmission module may be directly connected to the ground control terminal; and when a distance between the intelligent device and the ground control terminal is far, then the intelligent device is in the second state, and the bandwidth of the image transmission module may be relatively lower, so as to ensure the long-distance communication between the intelligent device and the ground control terminal.
Alternatively, when the intelligent device transmits a large image, it is then in the first state, and the bandwidth of the image transmission module may be set to be larger; and if the image transmitted by the intelligent device is small, then the intelligent device may be in the second state, and the bandwidth of the image transmission module may be adjusted to be smaller.
It may be understood that the image transmission module may have different bandwidths in different states, and the bandwidth in each state may be preset. When the intelligent device is switched from the first state to the second state, and if this involves an adjustment to the bandwidth of the image transmission module, then the bandwidth of the image transmission module just may be switched correspondingly.
Embodiment II: a first transmit power of the image transmission module of the intelligent device in the first state is switched to a second transmit power in the second state.
For example, when a distance between the intelligent device and the ground control terminal is close, then the intelligent device is in the first state, and the transmit power of the image transmission module maybe relatively lower, so that the image transmission module may be coupled with the ground control terminal at a close distance and reduce wireless radiation; and when a distance between the intelligent device and the ground control terminal is far, then the intelligent device is in the second state, and the transmit power of the image transmission module may be relatively higher, so as to ensure the long-distance communication between the intelligent device and the ground control terminal.
Alternatively, when the intelligent device transmits a large image, it is then in the first state, and the transmit power of the image transmission module may be set larger; and if the image transmitted by the intelligent device is small, then the intelligent device maybe in the second state, and the transmit power of the image transmission module may be adjusted to be smaller.
It may be understood that the image transmission module may have different transmit power in different states, and the transmit power in each state may be preset. When the intelligent device is switched from the first state to the second state, and if this involves an adjustment to the transmit power of the image transmission module, then the transmit power just needs to be switched correspondingly.
Embodiment III: a first brightness of an indicator lamp on the intelligent device in the first state is switched to a second brightness in the second state.
The indicator lamp on the intelligent device may be used to display at different degrees of brightness in different states. For example, the brightness of the indicator lamp may be lower if the intelligent device is in normal operation; and if some component of the intelligent device is in failure, the brightness of the indicator lamp may be adjusted to be higher, so that the staff may easily notice the failure and further take timely measures.
Alternatively, multiple indicator lamps may be arranged on the intelligent device, and different states may be represented by different combined brightness of indicator lamps. For example, assuming that there are 3 indicator lamps on the intelligent device, all 3 indicator lamps may be ON in the flight shooting state, only 2 indicator lamps need to be ON in the ground shooting state, and only 1 indicator lamp needs to be ON in other shooting states. Certainly, the above is exemplary only, and other brightness combinations may be further employed to represent different states in practical application.
Embodiment IV: a first color of the indicator lamp on the intelligent device in the first state is switched to a second color in the second state.
In order to identify various states of the intelligent device, each state may also be represented by setting the color of the indicator lamp, i.e., the color to be displayed by the indicator lamp of the intelligent device varies with the state. For example, the indicator lamp is in green in the flight shooting state, and the indicator lamp is in red or any other color in the ground shooting state. Alternatively, multiple indicator lamps may be arranged on the intelligent device, and the indicator lamps may display different color combinations in different states. For example, assuming that there are 3 indicator lamps, the 3 indicator lamps are displayed in a “red-green-red” combination in the flight shooting state, while the 3 indicator lamps are displayed in a “red-red-yellow” combination or only two of them are displayed, for example only two indicator lamps are displayed in two colors as “red-yellow”, in the ground shooting state. Certainly, the above is exemplary only, and other color combinations may be further employed to represent different states in practical application.
In addition, the embodiments as listed above are only those possible embodiments of switching of the state parameters. The practical application may further involve switching of other state parameters, such as switching of power, switching of camera parameter, switching of communication parameter and others. Certainly, there may also be other switching than the state parameters, for example switching of antennas. The embodiments of communication parameters and antenna switching will be described below.
Embodiment V: a first communication parameter of the intelligent device in the first state is switched to a second communication parameter of the intelligent device in the second state.
Among them, at the time of uplink transmission of data to the intelligent device (i.e., the ground control terminal transmits data to the intelligent device), this is mainly directed to control signals, while the data volume is small, so data stability, communication distance, penetration ability and diffraction ability need to be better guaranteed in the uplink transmission of data; and at the time of downlink transmission of data from the intelligent device (i.e., the intelligent device transmits data to the ground control terminal), this mainly involves image data, and the clearer the images, the better, so greater data throughput is needed during the downlink transmission of data.
Generally, the wireless communication links of an intelligent device are designed to be symmetrical, i.e., the uplink transmission and the downlink transmission employ the same wireless communication mode (i.e., using the same communication link), as shown in
But an asymmetric communication protocol structure may be adopted in one embodiment of the present disclosure. As shown in
Among them, the uplink data communication uses a frequency band less than 1 GHz, and the wireless signal is low in frequency, long in wavelength, strong in the ability to bypass obstacles, and larger in signal coverage in the same communication environment. The uplink data communication adopts a data modulation mode with lower frequency, and the simpler the modulation mode, the lower the receiving sensitivity of the device, and the larger the signal coverage in the same communication environment. While the downlink data communication uses a frequency band of 2.4 GHz or 5 GHz, and the wireless signal is high in frequency and short in wavelength; good communication requires an unobstructed distance, and a good sight distance from the sky to the ground. The downlink data communication adopts a higher-rate data modulation mode, and the more complex the modulation mode, the higher the receiving sensitivity of the device, and the stronger the data throughput capacity in the same communication environment.
Among them, when the intelligent device needs to transmit data to the ground control terminal, the communication mode may be switched to the downlink communication mode, and when the ground control terminal needs to transmit data to the intelligent device, the communication mode may be switched to the uplink communication mode. The communication parameters involved in the switching include signal wavelength, modulation mode, signal transmission power, receiving sensitivity and other parameters.
Embodiment VI: a first antenna of the intelligent device for transmitting and receiving signals in the first state is switched to a second antenna for transmitting and receiving signals in the second state.
For example, the first antenna may be used for signal transmission and reception in the flight shooting state, while the second antenna may be used for signal transmission and reception in the ground shooting state. Among them, the switching between the antennas is controlled by an antenna switching circuit on the intelligent device, i.e., the processor on the intelligent device generates an antenna switching instruction and controls the antenna switching circuit to switch from the first antenna to the second antenna. It may be understood that the antenna switching circuit may be a relay or a triode, and the antenna switching circuit may be used to cutoff the power supply to the first antenna and connect the second antenna with the power supply circuit, then indicating that the first antenna is disabled while the second antenna is enabled so as to complete the switching between the first antenna and the second antenna.
In addition, as an example, the intelligent device may implement the switching between shooting states, i.e., the state switching conditions include shooting state switching conditions. Therefore, when the intelligent device meets the shooting state switching conditions, the intelligent device may be switched from a first shooting state to a second shooting state.
A shooting state may refer to states for different objects to be shot. For example, when the object to be shot is a person, resolution of pixels needs to be higher in the shooting state, and bokeh may be required for shooting; and when the object to be shot is a landscape, resolution of pixels maybe set relatively lower in the shooting state, and bokeh is not required. Therefore, at the time of switching the shooting states, the corresponding shooting parameters may be switched to make them adaptive to shooting in different shooting states.
Certainly, the shooting states may also be distinguished according to the application scenario of the intelligent device. For example, the state parameters during the flight shooting and the ground shooting may also be different. For example, the indicator lamp may be turned ON during the flight shooting, and the indicator lamp may be controlled and turned off during the ground shooting; alternatively, the bandwidth of the image transmission module may be controlled to be lower during the flight shooting, and the bandwidth of the image transmission module maybe controlled to be higher during the ground shooting.
As an example, one of the first shooting state and the second shooting state may be a self-propelled shooting state, and the other may be a handheld shooting state.
Among them, the self-propelled shooting state refers to a shooting state of the intelligent device at the time of shooting while self-propelling. The self-propelled shooting state includes at least one of a flight shooting state, a land navigation shooting state and an underwater navigation shooting state.
The handheld shooting state refers to a shooting state in which a user is shooting with a handheld intelligent device. In the handheld shooting state, a terminal device may be arranged on the bracket on the intelligent device. At this time, the intelligent device is a handheld DV. Due to the short-range communication between the terminal device and the intelligent device, the intelligent device transmits in real time captured images to the terminal device for display. At this time, the external device with a power system has been removed from the intelligent device, and the user may handhold the intelligent device for shooting. The external device with a power system includes at least one of a UAV arm, an underwater driving device and a vehicle driving device.
When the intelligent device is switched from the self-propelled shooting state to the handheld shooting state, the external device with a power system may be removed from the intelligent device, i.e., it is determined that the intelligent device satisfies the shooting state switching conditions if change takes place in the connection state between the external device with a power system of the intelligent device and the body of the intelligent device.
Description will be made below by taking an example in which the self-propelled shooting state is the flight shooting state. At this time, the external device with a power system is an UAV arm.
The flight shooting state refers to a shooting state in which the intelligent device is shooting the ground from a high altitude. When the intelligent device is switched from the flight shooting state to the handheld shooting state, the UAV arm on the intelligent device may be removed, i.e., it is determined that the intelligent device meets the shooting state switching conditions if change takes place in the connection state between the UAV arm of the intelligent device and the body of the intelligent device.
It may be understood that when the intelligent device detects that the UAV arm is disconnected from the body of the intelligent device, it may automatically switch the flight shooting state to the handheld shooting state, and the switching process may specifically involve the switching between such state parameters as are listed in the above embodiments, e.g., the switching between the bandwidths of the image transmission module, the switching between the transmit powers of the image transmission module, the switching between the brightness of the indicator lamp and/or the switching between the antennas. On the contrary, when the intelligent device detects the connection between the arm and the body of the intelligent device, it may automatically switch from the shooting state to the flight shooting state, and the switching process therein also involves the switching between the parameters in the above embodiments.
For example, the bandwidth of the image transmission module may be 5 MHz/10 MHz in the flight shooting state, and when the intelligent device is switched to the handheld shooting state, the bandwidth of the image transmission module may be adjusted to 20 MHz to make the it reach the bandwidth required by the connection with a terminal device. On the contrary, at the time of switching from the handheld shooting state to the flight shooting state, the bandwidth of the image transmission module may be adjusted from 20 MHz to 5 MHz/10 MHz, thereby increasing the image transmission distance and enhancing the anti-interference ability.
Alternatively, the transmit power of the image transmission module is a normal transmit power in the flight shooting state, and at the time of switching to the handheld shooting state, the transmit power of the image transmission module may be reduced to about 8 dbm to achieve the short-range connection with a terminal device and reduce wireless radiation. On the contrary, at the time of switching from the handheld shooting state to the flight shooting state, the transmit power of the image transmission module may be switched from 8 dbm to the normal transmit power to provide the long-distance performance of connecting a remote terminal device.
Alternatively, the first antenna is used for signal transmission and reception in the flight shooting state, and the second antenna is used for signal transmission and reception in the handheld shooting state, i.e., the roundness of the radiation pattern of the first antenna is greater than that of the second antenna. Therefore, the roundness of the radiation pattern may be increased in the flight shooting state, and the greater the roundness, the smaller the signal change in all directions around the intelligent device. The first antenna may be arranged on the body of the intelligent device, and the second antenna may be arranged on the UAV arm of the intelligent device.
Alternatively, the brightness of the indicator lamp of the intelligent device is a first brightness in the flight shooting state, and the brightness of the indicator lamp is a second brightness in the handheld shooting state. Therefore, the brightness of the indicator lamp may also be adjusted from the first brightness to the second brightness at the time of switching from the flight shooting state to the handheld shooting state.
The brightness of the indicator lamp may be modulated by controlling the duty cycle of the output current to the indicator lamp by a LED driver on the intelligent device. If the first brightness is brighter than the second brightness, the duty cycle of the output current to the indicator lamp may be decreased, so that the brightness may be lowered. And in the handheld shooting state, the brightness will automatically reduce without dazzling. On the contrary, if the intelligent device is switched from the handheld shooting state to the flight shooting state, the duty cycle of the output current to the indicator may be increased.
In addition, if the handheld shooting state is different only in state parameters from the flight shooting state, the switching between the shooting state parameters may also be performed after a switching instruction is received. Among them, when it comes to the brightness of the indicator lamp, i.e., after an instruction on switching the shooting state is received, the brightness of the indicator lamp may be switched from the first brightness in the first state to the second brightness in the second state.
It shall be noted that the above switching between the shooting states may also involve switching of other state parameters. What is described above is only exemplary, and the state parameters to be switched may be set to meet the actual needs. For example, when there are multiple cameras on the intelligent device, this may also involve the switching between cameras, between powers, and between circuits.

One embodiment of the present disclosure provides a readable storage medium executing the method or process as executed by the intelligent device in the method example as shown in
This example discloses a computer program product comprising a computer program stored on a non-transient computer-readable storage medium. The computer program includes a program instruction. When the program instruction is executed by the computer, the computer may execute the methods as provided by the above method examples, for example, comprising: determining whether the intelligent device meets the state switching conditions; and switching the intelligent device from the first state to the second state when the state switching conditions are met.
The present disclosure also provides an intelligent device, which can be used in a handheld manner and can be used for flight, and can also be erected on a plane for use.
The intelligent device first comprises a handheld body (a body) 2100 (corresponding to the body 104 in the first aspect of the present disclosure) and a flight driving device (corresponding to the UAV arm 130 in the first aspect of the present disclosure). The handheld body 2100 can be connected with or separated from the flight driving device.
When the handheldbody 2100 is separated from the flight driving device, the overall size is small and can be held by a single hand so as to facilitate the use in a handheld mode.
When the handheld body 2100 is connected with the flight driving device, the flight driving device carries the handheld body 2100 to form a flyable mobile device for use in a flight device mode (corresponding to the self-propelled device mode in the first aspect of the present disclosure).
The intelligent device further comprises a support frame (corresponding to the bracket 122 in the first aspect of the present disclosure). At least the handheld body 2100 can be mounted on the support frame to form a device that can be erected on the ground or other planes for use in an erected device mode.
The intelligent device is equipped with a shooting module 2210 (corresponding to the image module 108 in the first aspect of the present disclosure) mounted on the handheld body 2100 and capable of working to collect images, videos, etc., during the use of the intelligent device whether in the handheld mode or in the flight device mode.
During the flight of the intelligent device, or in the handheld mode, the whole intelligent device when held by a user and moving may often bump or shake up and down due to movement, which easily leads to unclear imaging of the shooting module 2210. In order to improve the imaging effect, the handheld body 2100 is provided with a gimbal mechanism 2200 where the shooting module 2210 is mounted, the gimbal mechanism 2200 is used for adjusting the shooting module 2210 along with the shaking during movement so as to minimize the impact of bumping and shaking on the shooting module 2210 and maintain the shooting module 2210 stable.
When the shooting angle needs to be adjusted, the gimbal mechanism 2200 can also be used to change the shooting angle of the shooting module 2210. The gimbal mechanism 2200 can be a two-axis or three-axis gimbal. The shooting module 2210 is mounted on the same, and then the viewing angle of the shooting module 2210 is made oriented in different directions by regulating the rotation of each axis, so that images in more directions can be collected smoothly when the handheld body 2100 maintains the current state.
In other examples, the gimbal mechanism 2200 may also be used for the mounting of other devices, such as an object transport box, so as to facilitate smooth transport of goods.
A structure of the flight driving device may include a UAV fuselage forming a mounting position for the handheld body 2100, and a UAV arm 2500 mounted on the UAV fuselage.
The mounting position may be a concave cavity arranged at the bottom of the UAV fuselage (i.e., one side facing the ground during flight). The handheld body 2100 is fixed in the concave cavity of the UAV fuselage, the gimbal mechanism 2200 protrudes out of the concave cavity to move and facilitate the shooting module 2210 to collect images, and the flight driving device carries the handheld body 2100 to fly and work.
Alternatively, it may be a slot having an opening towards front of the UAV fuselage. The gimbal mechanism 2200 is arranged at one end of the handheld body 2100, and the other end of the handheld body 2100 is inserted into the slot.
To provide operation power, the intelligent device is equipped with a handheld mode battery 2300 and a flight mode battery 2400.
The flight mode battery 2400 of the intelligent device is mounted on the UAV fuselage, so the flight driving device can fly alone.
The handheld mode battery 2300 of the intelligent device is mounted at the mounting position of the handheld body 2100, so the handheld body 2100 can be used alone.
To reduce the volume of the intelligent device so as to provide a multifunctional intelligent device convenient for storage, further, the flight driving device is configured into the UAV arm 2500, and the handheld body 2100 is provided with a battery mounting position 2121 and an arm mounting position 2122 (corresponding to the structural connection port 117 in the first aspect of the present disclosure).
Namely, the flight device mode is developed when the handheld body 2100 and the battery connected thereto overall serve as the fuselage, and the UAV arm 2500 is connected to the arm mounting position 2122.
The intelligent device further comprises a connector comprising a male connector and a female connector 2123, wherein the female connector 2123 is disposed at the arm mounting position 2122 and the male connector at the UAV arm 2500.
On the female connector 2123 are integrated an arm detection interface, an arm power supply interface and a signal transmission interface, while on the male connector are arranged adapters corresponding to each interface. When the arm is connected to the arm mounting position 2122, the male connector mates with the female connector 2123, so that the UAV arm 2500 obtains operation power from the handheld body 2100 through the connector and exchanges control signals with the handheld body 2100.
At least one of the handheld mode battery 2300 and the flight mode battery 2400 is mounted at the battery mounting position 2121 of the handheld body 2100. When the handheld body 2100 works alone in the handheld mode, the handheld mode battery 2300 is mounted at the battery mounting position 2121. When it is needed to work in the flight device mode, the flight mode battery 2400 is then mounted at the battery mounting position 2121.
To improve the comfort level during hand-holding, when the handheld mode battery 2300 is mounted at the battery mounting position 2121, the handheld mode battery 2300 fills up the battery mounting position 2121 and shields the arm mounting position 2122 so as to protect the female connector 2123 of the connecter and make the handheld mode battery 2300 forma continuous handheld surface together with the handheld body 2100.
As shown in
The handheld mode battery 2300 is a small cuboid, which makes up the space of retraction, so as to form a large cuboid together with the handheld body 2100. Each edge of the cuboid is a rounded corner to further improve the hand-holding comfort.
When the handheld mode battery 2300 is connected with the handheld body 2100 to form the large cuboid, it provides operation power for the functional modules on the handheld body 2100, such as the gimbal mechanism 2200 and the shooting module 2210. Holding the large cuboid, the user can collect images by the shooting module 2210, adjust the shooting direction using the gimbal mechanism 2200 or maintain the shooting module 2210 stable.
To make it convenient to check the shooting effect during the handheld shooting, the intelligent device further comprises a screen module 2600. The shooting module 2210, the screen module 2600 and the gimbal mechanism 2200 are in electrical connection with the control system of the handheld body 2100.
On the stair face of the second step 2120 of the handheld body 2100 is disposed an expansion interface 2111, to which the screen module 2600 is connected, as shown in
The screen module 2600 is provided with a dial wheel 2610 which can be rotated to enlarge or reduce an image on the screen module 2600 in a handheld state. The screen module 2600 is also provided with a steering key, via which the rotation of the gimbal mechanism 2200 is controlled to change the shooting angle of the shooting module 2210. The screen module 2600 displays the shooting results of the shooting module 2210 in real time.
In one example, the screen module 2600 is provided with a secondary interface, to which other devices such as a radio device and a light filling device can be connected when the screen module 2600 is connected to the expansion interface 2111.
When it is needed to operate in the flight device mode, the flight mode battery 2400 is mounted at the battery mounting position 2121. As described above, the flight mode battery 2400 forms a fuselage with the handheld body 2100, and the external shape of the flight mode battery 2400 is constructed to make way for the arm mounting position 2122, thereby enabling the arm mounting position 2122 to be exposed so that the UAV arm 2500 can be mounted. When the UAV arm 2500 is connected to the arm mounting position 2122, the intelligent device is set into the flight device mode.
The capacity of the flight mode battery 2400 is greater than that of the handheld mode battery 2300 so as to be capable of powering both the handheld body 2100 and the flight driving device at the same time, thereby increasing the duration of flight.
As shown in
The flight mode battery 2400 supplies power to the handheld body 2100, and the UAV arm 2500 obtains operation power from the handheld body 2100 via the connector and exchanges control signals with the handheld body 2100.
There are two UAV arms 2500 in the left and right respectively. The intelligent device in the flight device mode may be with double rotors or multiple rotors, and it is with four rotors in this example.
Referring again to
One ends of the first arm 2510 and the second arm 2520 are connected to the connecting plug 2540, the connecting plug 2540 is used for entering from the socket and connecting the arm mounting position 2122. The male connector of the connector as mentioned above is disposed on the connecting plug 2540. When the connecting plug 2540 is connected to the arm mounting position 2122, the male connector mates with the female connector 2123.
The other ends of the first arm 2510 and the second arm 2520 are respectively provided with a propeller component 2530. The motor of the propeller component is mounted on the UAV arm 2500, and the blades of the propeller component 2530 are mounted on the output shaft of the motor. The power supply line of the motor is routed within the UAV arm 2500 and connected to the male connector. After the UAV arm 2500 is mounted at the arm mounting position 2122, the motor can obtain operation power and receive control signals.
In one example, at least one of the first arm 2510 and the second arm 2520 can rotate relative to the connecting plug 2540. When the UAV arm 2500 is removed from the handheld body 2100, the first arm 2510 and the second arm 2520 can rotate to be parallel and close together, thereby reducing the space occupied by the overall UAV arm 2500 to facilitate storage and carrying.
During flight, the intelligent device may be so far away from the user that sometimes it is not convenient to accurately judge the environment of the device by naked eye, which then easily make the device impacted and out of control. In order to alleviate this problem, the intelligent device further comprises a sensor module, which includes a GPS positioning module, a first binocular vision sensor 2710 and a second binocular vision sensor 2720 arranged on the handheld body 2100.
The GPS positioning module is used to acquire in general the geographical location of the intelligent device, which is convenient for navigation and loss prevention. The first binocular vision sensor 2710 and the second binocular vision sensor 2720 can be used to detect the environment around the intelligent device in real time to know whether there are obstacles, and can also be used to detect and find targets.
The first binocular vision sensor 2710 is located at one end of the handheld body 2100 close to the gimbal mechanism 2200 to detect front obstacles or targets during flight.
In one example, the first binocular vision sensor 2710 may be integrated on the handheld body 2100, and a detection head thereof is arranged to protrude out of the handheld body 2100 and can rotate outside the handheld body 2100.
When the intelligent device is in the flight device mode, the detection head rotates and is oriented toward the front, namely protruding towards the direction of the gimbal mechanism 2200, and is located above the shooting module 2210. Since the shooting module 2210 generally rotates to be upwards, this position is convenient for detection and does not affect the gimbal mechanism 2200 to drive the shooting module 2210 to rotate for shooting.
When the intelligent device is in the handheld mode, the shooting of the shooting module 2210 requires omni-directional rotation for shooting. If the detection head still protrudes towards the gimbal mechanism 2200, this may affect the rotation of the gimbal mechanism 2200. Therefore, the detection head rotates to be away from the gimbal mechanism 2200 in the handheld mode.
In the intelligent device according to this example as shown in
The second binocular vision sensor 2720 is located at a side of the handheld body 2100. When the intelligent device flies in the air in the flight device mode, the side will face the ground so as to detect obstacles or targets below the route during flight.
As shown in
The first side is parallel to the fourth side, and the second side is parallel to the third side. In the flight device mode, the first side and the fourth side are parallel to the horizontal plane, the first side is located above while the fourth side is located below; meanwhile, the second side and the third side are parallel to the vertical plane, from which the UAV arm 2500 protrudes horizontally.
It should be noted that such terms as “horizontal” and “vertical” do not mean that components are required to be absolutely horizontal or vertical, but can be slightly inclined. For example, “horizontal” only means that a direction of a structure is more horizontal than “vertical”, and does not mean that the structure must be completely horizontal, but can be slightly inclined.
In order to improve the detection effect of the second binocular vision sensor 2720 and the shooting effect of the shooting module 2210, the handheld body 2100 is also provided with a fill-in light 2730 located on the same side of the handheld body 2100 as the second binocular vision sensor.
Referring again to
When it is needed to operate in the erected device mode, the handheld body 2100 is at least mounted on the support frame, and is connected with the handheld mode battery 2300 or the flight mode battery 2400 to obtain power. While the support frame is not shown in the drawings, those skilled in the art should understand that the support frame is a bracket capable of being erected and fixed on the ground, table top, and other flat or uneven surfaces, such as a tripod.
In one example, the support frame has a placement plane, which is partially concave to form a mounting groove to clamp and fix the handheld body 2100 and the battery connected thereto.
In one example, the support frame is formed with a threaded column, and at least one of the handheld body 2100, the handheld mode battery 2300 and the flight mode battery 2400 is provided with a nut capable of being thread-connected with the threaded column.
For example, the nut is formed on the handheld body 2100. As can be seen in
As one further example, the nut is formed at other positions on the surface of the handheld body 2100, so that after the flight mode battery 2400 is mounted, and when the end face of the handheld body 2100 away from the gimbal mechanism 2200 is blocked by the flight mode battery 2400, the handheld body 2100 can also connect the threaded column via the nut so as to operate in the erected device mode.
As another example, in addition to the nut disposed on the end face of the handheld body 2100 away from the gimbal mechanism 2200, a same nut is also formed on the flight mode battery 2400. When the handheld body 2100 is connected with the flight mode battery 2400, even if the end face of the handheld body 2100 away from the gimbal mechanism 2200 is blocked by the flight mode battery 2400, the nut on the flight mode battery 2400 can also be connected to the threaded column of the support frame to be mounted on the support frame and operate in the erected device mode.
The case may also be that nuts are respectively disposed on the handheld mode battery 2300 and the flight mode battery 2400. Whether the handheld body 2100 is connected with the handheld mode battery 2300 or with the flight mode battery 2400, the threaded column of the support frame can be connected with the nuts on the batteries so as to operate in the erected device mode.
Multiple interfaces are included in the second aspect of the present disclosure, including mechanical interfaces and electrical interfaces, some or all of which correspond to the first interface in the first aspect of the present disclosure. For example, the interface on the handheld body 2100 for connecting the handheld mode battery and the flight mode battery, and the arm mounting position 2122 correspond to the first interface 101 in the first aspect of the present disclosure. The handheld mode battery 2300, the flight mode battery 2400 and the arm 2500 in the second aspect of the present disclosure correspond to the external devices in the first aspect of the present disclosure. When the handheld mode battery 2300 is connected to the handheld body 2100, the intelligent device operates in the handheld mode; when the flight mode battery 2400 and the arm 2500 are connected to the handheld body 2100, the intelligent device operates in the self-propelled mode (the flight device mode). The handheld body and the flight driving device of the present disclosure can be connected or separated, the handheld body can be used alone in the handheld mode, and can be connected with the flight driving device to be used in the flight device mode, thus solving the problem in the art that the existing intelligent device only has a single usage mode.
Furthermore, the handheld mode battery 2300 and the flight mode battery 2400 in the second aspect of the present disclosure correspond to the second power source in the first aspect of the present disclosure, for supplying power to the external devices and/or the intelligent device.
The features in the first and second aspects of the present disclosure can be combined in any manner, which falls into the protection of the present disclosure, unless there is an obvious conflict which makes such combination impossible.
The handheld body and the flight driving device of the intelligent device provided by the present disclosure can be connected or detached. The handheld body can be used alone in the handheld mode, and can be connected with the flight driving device to be used in the flight device mode, thereby solving the problem in the art that the existing intelligent device only has a single usage mode.
In some embodiments, the gimbal mechanism is provided on the handheld body. The gimbal mechanism serves to adjust the shooting angle and balance and stabilize the shooting module during the movement of the intelligent device, thereby improving the shooting effect.
In some embodiments of the present disclosure, optionally, the intelligent device further comprises a handheld mode battery and a flight mode battery. The handheld mode battery is installed on the handheld body and is used to supply power to the handheld body so that the handheld body can be used in a handheld manner. The flight mode battery is installed on the handheld body to supply power to the handheld body and the flight driving device at the same time in order to have a longer duration of flight.
In some embodiments, compared to the capability of the handheld mode battery, the flight mode battery has a greater capacity, so as to have a longer duration of flight in the flight device mode. Or the handheld mode battery may be configured to have a smaller volume so that it may be grasped easily.
In some embodiments, the flight mode battery may be integrated with the handheld body as the UAV fuselage, which may have the UAV arms installed thereon to carry the UAV fuselage to fly. When the UAV arms are detached, this does not affect the handheld body connected with the handheld mode battery for the handheld use. The overall structure is simple and compact and does not have redundant component and is convenient for use.
In some embodiments of the present disclosure, when the flight mode battery is installed on the handheld body, it may make way for the arm mounting position, so that the UAV arms may be installed on the arm mounting position, and the flight mode battery makes the UAV arm close to the handheld body to avoid the separation of the UAV arms. So the handheld body, the UAV arms and the flight mode battery may form a flyable device, without the need to have an additional device to anchor or fix the UAV arms. The overall structure is simple and compact. After the detachment of the flight mode battery, the three parts separate and can be used and stored easily and separately.
