Description

Technical Field

[0001] The invention relates to a storage, transportation and launching integrated box for a rotary-wing UAV, in particular to a storage, transportation and launching integrated box for a coaxial double-rotor UAV, belonging to the technical field of storage, transportation and launching of UAVs. Background Art

[0002] Drones are playing an increasingly important role in both military and civilian applications. The traditional method of using drones is that after the drones are transported to the designated location, the operator takes the drone out of the packaging box, unfolds the folding mechanism, adjusts the blades, and then places the drone on the ground or on the launch pad for takeoff. In order to reduce the time it takes for drones to go from storage and transportation to flight and improve the operating efficiency of drones, drone storage, transportation, and launch integrated boxes are being used to achieve seamless transition from storage to flight. Operators can launch and take off drones without touching the drones, or even the storage, transportation, and launch integrated boxes.

[0003] In the prior art, there are two forms of implementation of the lifting or launching device. One is to launch through the primer of the launch box, the airbag or the rocket of the UAV itself; the other is to launch the UAV through the guide rail, the screw rod and other mechanisms. The first method cannot be reused, and the primer, airbag, fuel, etc. need to be replaced when used again, which can provide the initial speed for the UAV. The second method can be reused, and the UAV is pushed out of the box by electromechanical devices such as motors and screw rods, which cannot provide the initial speed for the UAV. Helicopters, coaxial twin-rotor UAVs, multi-rotor UAVs and other aircraft can take off and land vertically, and do not require an initial speed for takeoff, so there is no need to use the first form of launch; however, the second form of motor screw rod coordination is prone to jamming or jamming when used for a long time or in a complex environment, which affects the repeated launch of the UAV. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a storage, transportation and launching integrated box for a coaxial twin-rotor UAV which can realize repeated launching and has a stable and smooth launching process.

[0005] In order to solve the above technical problems, the present invention provides a storage and transportation launch integrated box for a coaxial twin-rotor UAV, comprising a storage and transportation launch box, wherein the storage and transportation launch box is respectively a storage and transportation box body at the bottom and a storage and transportation box cover at the top. A plurality of storage and transportation box bodies can be arranged in the storage and transportation launch box, each of which can store a UAV. The storage and transportation box cover at the top provides a switchable launch outlet for the storage and transportation box body, and the storage and transportation box cover is pushed open after the UAV is launched. It also includes a launch component and a control component, wherein a plurality of the launch components are respectively installed in a plurality of launch box bodies, and a UAV to be launched is correspondingly installed on each launch component; The launching component comprises a driving mechanism with a belt transmission structure; the driving motor is used to provide power to the driving mechanism, and the launching component controls the start and stop and forward and reverse rotation of the driving motor through the control component, thereby realizing the launch-reset cycle operation of the launching component.

[0006] The launch component and the storage and transportation launch box are both provided with limit components, and the limit components are used to limit the movement range of the launch component in the storage and transportation launch box; the limit components include multiple groups of distance sensors, and the control component triggers the limit signal of the limit component, and then uses the limit signal to control the forward and reverse rotation of the drive motor.

[0007] The driving motor and the limit assembly are both electrically connected to the control assembly; When the distance sensor moves into the sensing range of the proximity switch, the proximity switch sends an electrical signal to the control component, which then regulates the drive motor through the control component to achieve limit control of the transmitting component and repeated transmission reset.

[0008] The launching assembly also includes a connecting piece and a launching bracket. The launching bracket is connected to the driving mechanism via the connecting piece, and the launching bracket is used to support the UAV.

[0009] Furthermore, by installing the distance sensor on the moving launch bracket and fixing the proximity switch that receives the distance signal on the storage and transportation launch box, the distance sensor installed on the launch bracket can more accurately reflect the launch status of the UAV, especially the movement range of the launch component in the storage and transportation launch box.

[0010] The driving mechanism includes a driving motor, a transmission synchronous belt, a synchronous pulley and a launching synchronous belt, and the driving motor is installed inside the storage and transportation box body; The output end of the drive motor is connected to a transmission synchronous belt, and multiple sets of transmission synchronous belts can be provided to achieve more reasonable and efficient power transmission. The transmission synchronous belt is used to transmit the output power of the drive motor; The transmission synchronous belt is connected to the launch synchronous belt through a plurality of synchronous pulleys, and the plurality of transmission synchronous belts are used for power transmission and installation through a plurality of synchronous pulleys; the launch synchronous belt is connected to the launch bracket through a connecting piece; It is worth noting that the length of the launch timing belt should not be less than the movement stroke of the UAV in the storage and transportation launch box, that is, the launch timing belt needs to ensure that it drives the launch bracket to move and enables the UAV on the launch bracket to obtain sufficient launch acceleration; Furthermore, the launch synchronous belt is used to drive the launch bracket to move.

[0011] A sliding guide rail is arranged inside the storage and transportation box body along the movement direction of the launching bracket, and the sliding guide rail is slidably connected with the launching bracket through a sliding bearing.

[0012] In order to ensure the movement stability of the launching bracket during launching, multiple sliding guide rails are slidably connected to the launching bracket, thereby ensuring that the overall linear movement of the launching bracket is carried out along the sliding guide rails, and the sliding guide rails are installed along the launching direction, thereby ensuring the stability of the launching.

[0013] The limit assembly includes a switch trigger and a limit switch, wherein the switch trigger is mounted on the launch bracket, thereby ensuring that the movement of the launch bracket can be recorded by the switch trigger, and the movement of the launch bracket reflects the movement of the UAV in the storage and transportation launch box; Furthermore, multiple limit switches are installed at different positions on the storage and transport box body, and the moving switch trigger is detected by the limit switch. Once the signal of the switch trigger is received, the control component transmits different signals to the drive motor for signal sources at different positions. The drive motor includes the execution operations of start-forward-stop-reverse-stop; the limit switch is used to detect the moving position of the switch trigger on the launching bracket.

[0014] An operating component is adsorbed on the outside of the storage and transportation launch box, and the operating component realizes human-computer interaction through a control panel thereon, and the control panel is connected to the control component through an extension cable; The control panel is provided with a wireless transceiver module for remote control.

[0015] The storage, transportation and launching integrated box for the coaxial twin-rotor UAV of the present invention further comprises a temperature sensor and a temperature control component. A plurality of the temperature sensors and the temperature control component are installed in the storage and transportation box body to collect temperatures at different positions. The temperature sensor and the temperature control component are both connected to the control component. The control component controls the temperature control component through the temperature signal of the temperature sensor, which mainly includes calling the temperature actuators at different positions, that is, performing local heating at different positions of the UAV in the storage and transportation launch box, thereby achieving overall balanced preheating of the UAV.

[0016] The temperature sensor detects and compares the temperatures at different locations, and then controls the temperature control component to adjust the temperature through the control component.

[0017] The temperature control component includes a temperature control power supply, a heater and an insulation wall panel. The temperature control power supply is used to power the heater. Multiple heaters adjust the temperature at different positions on the drone. The insulation wall panel is arranged on the inner wall of the storage and transportation launch box. The insulation wall panel is used to preserve the internal temperature to avoid the loss of preheating temperature, affect the heating effect, and increase energy consumption.

[0018] The beneficial effects of this application are as follows: 1. This application achieves smooth launching power for the UAV by driving the coordinated use of multiple sets of synchronous belts, and uses a limit assembly to control the driving motor, so that the launching synchronous belt can start and stop flexibly and rotate forward and reverse within a limited stroke, thereby making the launching action of the UAV in the storage and transportation launch box smoother and more flexible, and can be launched repeatedly without the need for charging or replacing materials.

[0019] 2. The storage and transportation launch box of the present application is also provided with a temperature control component, which can preheat the UAV loaded in the storage and transportation launch integrated box in a low temperature environment, improve the starting performance of the UAV in a low temperature environment, and prevent damage to the onboard battery caused by low temperature starting.

[0020] 3. The exterior of the storage and transportation launch box of the present application is also provided with an operating component for easy operation, wherein the operating panel can be stored on the storage and transportation launch box, or it can be dragged and extended several meters or tens of meters away for the operator to operate inside the vehicle or behind a shelter, and it can also be remotely controlled wirelessly. It has a variety of usage methods and can be suitable for different usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-7 As shown, the present application provides a storage, transportation and launching integrated box for a coaxial twin-rotor UAV, including a storage, transportation and launching box 2, which comprises a lower storage and transportation box body 21 and an upper storage and transportation box cover 22, and also includes a launching assembly 3 and a control assembly 4. A plurality of launching assemblies 3 are installed inside the launching box body, and each launching assembly 3 stores a UAV 1.

[0026] like Figure 1 As shown, the launching assembly 3 includes a driving motor 31 and a driving mechanism 32 having a belt transmission structure.

[0027] like Figure 2 and Figure 3 As shown, both the launching assembly 3 and the storage and transportation launching box 2 are provided with a limit assembly 5 , and the limit assembly 5 is used to limit the movement stroke of the launching assembly 3 in the storage and transportation launching box 2 .

[0028] The driving motor 31 and the limiting assembly 5 are both connected to the control assembly 4 .

[0029] The control component 4 triggers the limit signal of the limit component 5, and then uses the limit signal to control the forward and reverse rotation of the drive motor 31.

[0030] like Figure 2 As shown, the launching assembly 3 further includes a connecting member 33 and a launching bracket 34 . The launching bracket 34 is connected to the driving mechanism 3 via the connecting member 33 , and the launching bracket 34 is used to support the UAV 1 .

[0031] like Figure 3 As shown, the driving mechanism 32 includes a driving motor 31, a transmission synchronous belt 321, a synchronous pulley 322 and a launching synchronous belt 323, and the driving motor 31 is installed inside the storage and transportation box body.

[0032] The output end of the driving motor 31 is connected to a transmission synchronous belt 321 , and the transmission synchronous belt 321 is used to transmit the output power of the driving motor 31 .

[0033] The transmission synchronous belt 321 is transmission-connected to the launching synchronous belt 323 through a plurality of synchronous pulleys 322 , and the launching synchronous belt 323 is connected to the launching bracket 34 through a connecting piece 33 ; the launching synchronous belt 323 is used to drive the launching bracket 34 to move.

[0034] The configuration quantity of the driving mechanism 32 corresponds to the maximum loading quantity of the coaxial twin-rotor UAV 1. The power and control battery provides energy for the driving motor 31, and the control component 4 provides a signal for the driving motor 31. The driving motor 31 rotates to drive the transmission synchronous belt 321 to rotate, and then drives the launch synchronous belt 323 to rotate through the synchronous belt pulley 322.

[0035] For the specific implementation of the control component 4, a sensor can be used to receive a physical signal and send a signal to the control component 4, thereby uniformly regulated by the control component 4. The control chip used by the control component 4 can be reasonably selected by technicians in this field according to the actual implementation, and the same applies to the circuit control part of this application.

[0036] A sliding guide rail 35 is provided inside the storage and transport box body 21 along the movement direction of the launching bracket 34 , and the sliding guide rail 35 is slidably connected to the launching bracket 34 via a sliding bearing 36 .

[0037] The launch bracket 34 is fixedly connected to the launch bracket 34 through the connecting piece 33, and the launch bracket 34 is driven by the launch synchronous belt 323 to realize the up and down movement. The launch bracket 34 moves along four sliding guides 35 through four sliding bearings 36, and the sliding guides 35 play the role of supporting and positioning the launch bracket 34 and the UAV 1.

[0038] like Figure 3 As shown, the limit assembly 5 includes a switch trigger 51 and a limit switch 52. The switch trigger 51 and the limit switch 52 are a pair of distance sensors used in conjunction with each other, and are used to reflect and timely collect the movement position of the launch bracket 34. Therefore, the switch trigger 51 is installed on the launch bracket 34, and then by installing sensors at multiple positions, the launch bracket 34 at different positions can be reasonably regulated; A plurality of limit switches 52 are installed at different positions on the storage and transport box body 21 , and the limit switches 52 are used to detect the movement position of the switch trigger 51 on the launching bracket 34 .

[0039] Furthermore, when the middle position limit switch 52 detects the switch trigger 51 for a long time, that is, the launch bracket 34 is stuck in the middle of the storage and transportation launch box 2, this reflects that the launch bracket 34 may be damaged, the sliding guide rail 35 may be worn or the lubricating oil is insufficient, or the synchronous belt may be faulty, etc., and then the control component 4 is programmed to obtain a feedback signal from the middle switch trigger 51, and an alarm is issued to remind the staff to troubleshoot the problem.

[0040] like Figure 2 , Figure 5 and Figure 6 As shown, an operating component 6 is adsorbed on the outside of the storage and transport launch box 2, and the operating component 6 realizes human-computer interaction through a control panel 61 thereon, and the control panel 61 is connected to the control component 4 through an extension cable 62; The operating assembly 6 and the drive mechanism 32 are powered by a power and control battery. The control panel 61 can be attached to the storage box body through a magnetic connection, making it convenient for personnel to approach the loading or debugging of the drone; The extension cable 62 can be pulled out and extended from the storage box, and the control panel 61 can be dragged into the vehicle or behind the shelter for the operator to operate at a medium distance; a wireless transceiver module 63 is also installed in the operating component 6 for receiving remote control signals, thereby achieving remote control operation without relying on the control panel 61.

[0041] The control panel 61 is provided with a wireless transceiver module 63 for remote control.

[0042] like Figure 2 and Figure 4 As shown, a storage, transportation and launching integrated box for a coaxial twin-rotor UAV also includes a temperature sensor 7 and a temperature control component 8. Multiple temperature sensors 7 and temperature control components 8 are installed in the storage and transportation box body 21 for collecting temperatures at different positions; the temperature sensor 7 and the temperature control component 8 are both connected to the control component 4.

[0043] The temperature sensor 7 detects and compares the temperatures at different positions, and then controls the temperature control component 8 to adjust the temperature through the control component 4.

[0044] like Figure 4 As shown, the temperature control component 8 includes a temperature control power supply 81, a heater 82 and a heat preservation wall plate 83. The multiple heaters 82 adjust the temperature of different positions on the drone 1. The temperature control power supply 81 supplies power to the heater 82. The signal of the temperature sensor 7 is connected to the control component 4. Multiple temperature sensors 7 are arranged in the storage and transportation launch box 2 to collect the temperature of different positions. After data processing, the data is compared with the set upper and lower limit temperatures. If the temperature is lower than the lower limit, the heater 82 is controlled to be turned on, and if the temperature is higher than the upper limit, the heater 82 is controlled to be turned off, so as to control the temperature in the storage and transportation launch box 2 within a suitable range. The heat-insulating wall panel 83 is made of heat-insulating material and is pasted on the inner wall of the storage and transportation box body 21. The heat-insulating wall panel 83 plays a role of heat preservation and reduces the heat dissipation from the box to the outside.

[0045] The driving mechanism 32, the temperature control component 8, and the operating component 6 are all connected to the control component 4, which performs signal transmission and control. The storage and transportation box cover 22 is installed above the storage and transportation box body. The coaxial twin-rotor drone pushes open the storage and transportation box cover 22 during the process of being lifted out of the storage and transportation launch box 2.

[0046] like Figure 6 and Figure 7 As shown, when the drone needs to be stored or transported, the operator controls the driving motor 31 to reverse through the operation panel, and the driving motor 31 drives the transmission synchronous belt 321 to rotate. The power is transmitted through multiple synchronous pulleys 322 and the transmission synchronous belt 321, thereby driving the launch synchronous belt 323 to move. One side of the launch synchronous belt 323 is connected to the launch bracket 34, thereby, the launch synchronous belt 323 drives the launch bracket 34 to move downward until the launch bracket 34 moves to the bottom end of the storage and transportation launch box 2, and at the same time, the switch trigger 51 on the launch bracket 34 is sensed by the limit switch 52 at the lower end of the storage and transportation launch box 2, and then the driving motor 31 stops reversing under the control of the control component 4, and then the launch component 3 completes the storage and transportation preparation; Furthermore, the operator only needs to open the storage and transportation box cover 22 on the top of the storage and transportation launch box 2, and fold the UAV 1 and put it into the storage and transportation launch box 2 to complete the storage and transportation operation of the UAV; At this time, the lower end of the drone 1 is in contact with the launching bracket 34; When it is necessary to launch the drone, the operator uses the wireless transceiver module 63 on the operating component 6 to perform wireless remote control operations, and issues a launch command to the control component 4 through remote control, and then the control component 4 controls the drive motor 31 to rotate forward, so that the launch pulley obtains the initial rotation speed, and at the same time, the launch pulley drives the launch bracket 34 on one side to move from bottom to top, thereby, the launch bracket 34 moves upward from the bottom of the storage and transportation launch box 2 along the sliding guide rail 35, and then the launch bracket 34 drives the drone 1 thereon to obtain the launch acceleration, until the launch bracket 34 moves to the top of the storage and transportation launch box 2, and the switch contactor on the launch bracket 34 and the limit switch 52 on the upper part of the storage and transportation launch box 2 are mutually induced, at this time, the control component 4 obtains the induced electrical signal, and then the drive motor 31 stops, from then on, the launch bracket 34 stops moving, the drone 1 pushes open the storage and transportation box cover 22 and is launched, the drone blades leave the constraint of the storage and transportation box body 21, and automatically unfold under the action of the spring, and the drone can enter the flight state after receiving the remote control take-off command.

[0047] Although the present disclosure has been described in detail above with general descriptions and specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements may be made based on the embodiments of the present disclosure. Therefore, these modifications or improvements made without departing from the spirit of the present disclosure are within the scope of protection claimed by the present disclosure.
