Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an integrated foldable unmanned aerial vehicle. Background Art

[0002] Drones have unique flying capabilities and are small in size. They have broad prospects in aerial photography, atmospheric detection, traffic monitoring, resource exploration, power inspection, forest fire prevention, agriculture, and military use.

[0003] Existing drones usually do not have a folding function when in use, which makes it difficult to store the existing drones and easily damage the rotor and support arm parts of the drone. At the same time, existing drones usually use cameras for shooting when in use, but due to the influence of the environment, impurities such as dust, mosquito corpses, etc. are usually adhered to the surface of the drone camera, but existing drones usually do not have a camera cleaning function. If the impurities on the camera are not cleaned, the camera's shooting clarity will be affected, affecting the shooting effect. At the same time, existing drones usually do not have a camera protection function. When a drone crashes due to an operational error, the unprotected camera will usually crash together. However, since the camera is usually expensive and contains shooting data, if the camera is damaged, it will not only affect the cost, but also may lose data. Summary of the invention

DETAILED DESCRIPTION

[0074] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0075] Reference Figure 1-Figure 12 An integrated folding drone includes a housing 1 and a lens 9. A mounting groove 10 is provided at the lower portion of the housing 1. The lens 9 is disposed in the mounting groove 10. The drone also includes:

[0076] The protective cover 12 is slidably disposed on the housing 1 and can cover the mounting groove 10 to protect the lens 9 .

[0077] The buffer assembly is used for buffering, and includes a first airbag 5 and a second airbag 11 . The first airbag 5 is fixedly arranged on the outer annular surface of the protective cover 12 , and the second airbag 11 is fixedly arranged on the bottom of the shell 1 .

[0078] The cleaning component is located in the mounting groove 10 and is used for cleaning the lens 9 and driving the protective cover 12 to move.

[0079] The transmission assembly is arranged at the inner lower part of the housing 1 and is used to connect the protective cover 12 and the cleaning assembly.

[0080] The moving component is arranged in the installation groove 10, and the cleaning component is installed on the moving component. The moving component is used to drive the cleaning component to move up and down.

[0081] A storage groove 4 is provided at the upper portion of the housing 1 , a support arm 3 is rotatably provided at the top of the storage groove 4 , and a foldable propeller 2 is provided at the outer end of the support arm 3 .

[0082] In a specific embodiment of the present invention, the protective cover 12 is mainly used to close the mounting slot 10, which can be moved up and down under the cooperation of the transmission component and the cleaning component, thereby achieving the effect of opening and closing the mounting slot 10. During normal flight shooting, the protective cover 12 is located above the mounting slot 10, that is, the state of opening the mounting slot 10. In this state, the normal shooting operation of the lens 9 is not affected. During storage and carrying, the protective cover 12 can be moved downward to close the mounting slot 10 to protect the lens 9 from external collisions; the storage slot 4 provided can be used to store the support arm 3 and the propeller 2, thereby protecting the support arm 3 and the propeller 2 during storage and carrying, and the rotation connection between the support arm 3 and the storage slot 4 The connection can be set to a rotating connection with damping to ensure the stability of the support arm 3; the buffer component is mainly used to play a buffering and protective role when the UAV loses control and falls to the ground. Specifically, when falling to the ground, the first airbag 5 and the second airbag 11 are relied on to achieve soft contact with the ground. At the same time, a UAV attitude sensor is installed inside the UAV. If it loses control, the UAV attitude sensor senses that it is in an out-of-control state, and the protective cover 12 will close the installation groove 10 to protect the lens 9; the moving component is mainly used to control the position of the cleaning component. Under normal circumstances, the moving component drives the cleaning component away from the lens 9, which does not affect the normal shooting of the lens 9. When cleaning the lens 9, the moving component drives the cleaning component to move to the lens 9 to perform the cleaning operation.

[0083] The cleaning kit includes:

[0084] The cleaning box 8 is arranged on the moving assembly. Specifically, the cleaning box 8 is in the shape of a rectangular parallelepiped and is empty inside.

[0085] The partition 24 is fixedly arranged inside the cleaning box 8, and divides the cleaning box 8 into a liquid storage chamber 22 and a water storage chamber 32. The liquid storage chamber 22 stores lens cleaning liquid, and the water storage chamber 32 stores clean water.

[0086] There are two connecting tubes 19, which respectively penetrate a liquid storage chamber 22 and a water storage chamber 32, and the connecting tubes 19 can slide on the cleaning box 8; specifically, in this embodiment, two liquid storage chambers 22 and two water storage chambers 32 are symmetrically arranged with the center position of the cleaning box 8 as the boundary, and there are four corresponding connecting tubes 19 in total, and the four connecting tubes 19 correspond to the above-mentioned four chambers respectively.

[0087] The through hole 17 is opened at one end of the connecting pipe 19, and the end surface of the connecting pipe 19 at this location is closed.

[0088] The cleaning kit also includes:

[0089] The first square tube 21 is fixedly connected to the other end of the connecting tube 19 that passes through the liquid storage chamber 22 (i.e., the end away from the through hole 17), and the first square tube 21 is communicated with the connecting tube 19, and the first square tube 21 is slidably connected to the cleaning box 8.

[0090] The second square tube 27 is fixedly connected to the other end of the connecting tube 19 that passes through the water storage chamber 32 (i.e., the end away from the through hole 17), and the second square tube 27 is communicated with the connecting tube 19, and the second square tube 27 is slidably connected to the cleaning box 8.

[0091] The first elastic member 18 is arranged on one end of the connecting tube 19 close to the through hole 17; specifically, the first elastic member 18 can be a spring, one end of the first elastic member 18 is fixedly connected to the end of the connecting tube 19, and the other end is fixedly connected to the cleaning box 8.

[0092] The first square tube 21 is close to the liquid storage chamber 22 under the action of the corresponding first elastic member 18, and the second square tube 27 is close to the water storage chamber 32 under the action of the corresponding first elastic member 18. In the above state, the through hole 17 on the connecting tube 19 is located outside the cleaning box 8.

[0093] The outer side surface of the first square tube 21 is provided with a liquid outlet 20 and fixedly provided with a brush (not shown in the figure, the brush can be a cloth brush suitable for wiping the lens 9), and the outer side surface of the second square tube 27 is provided with a water outlet 26 and fixedly provided with a scraper 25.

[0094] The cleaning kit also includes:

[0095] The first magnetic block 28 is fixedly disposed on a surface of the first square tube 21 close to the adjacent second square tube 27 .

[0096] The second magnetic block 31 is fixedly disposed on the surface of the second square tube 27 close to the adjacent first square tube 21. The first magnetic block 28 and the second magnetic block 31 are staggered, and the first magnetic block 28 is closer to the middle position of the cleaning box 8 than the second magnetic block 31.

[0097] The guide rod 30 is fixedly arranged in the inner middle part of the cleaning box 8. Specifically, the cross section of the guide rod 30 is square, which can prevent the sliding magnet 33 from rotating on the guide rod 30.

[0098] The sliding magnetic block 33 is slidably disposed on the guide rod 30 .

[0099] The second elastic member 29 is arranged on the guide rod 30, and exerts a force on the sliding magnetic block 33 close to the center of the cleaning box 8, but not at the exact center, that is, there is still a distance from the exact center (refer to Figure 7), specifically, the second elastic member 29 can be a spring, the second elastic member 29 is sleeved on the guide rod 30, one end of which is fixedly connected to the inner end surface of the cleaning box 8, and the other end is connected to the sliding magnetic block 33. Under normal conditions, the sliding magnetic block 33 is close to the middle position of the cleaning box 8 under the action of the second elastic member 29.

[0100] The surface magnetic poles of the sliding magnet 33 and the first magnet 28 that are close to each other are of the same polarity, and the surface magnetic poles of the sliding magnet 33 and the second magnet 31 that are close to each other are of the same polarity; specifically, when the sliding magnet 33 moves to the position of the first magnet 28, that is, when the projection of the sliding magnet 33 is on the first magnet 28, the first magnet 28 can be moved away from the liquid storage chamber 22 due to the repulsion of the like magnetic poles. Similarly, when the sliding magnet 33 moves to the position of the second magnet 31, the second magnet 31 can be moved away from the water storage chamber 32.

[0101] When the cleaning assembly is in use, the cleaning box 8 is moved to the front of the lens 9 under the drive of the moving assembly, and then the first motor 7 is started to rotate the cleaning box 8. Under the action of centrifugal force, the sliding magnetic block 33 can overcome the force of the second elastic member 29 to move. When the sliding magnetic block 33 moves to the position of the first magnetic block 28, the first magnetic block 28 will move in the direction away from the liquid storage chamber 22, thereby driving the first square tube 21 to overcome the force of the first elastic member 18 and move away from the liquid storage chamber 22, so that the brush on the first square tube 21 is attached to the lens 9 for wiping. At the same time, the through hole 17 on the corresponding connecting tube 19 will enter the liquid storage chamber 22, and the lens in the liquid storage chamber 22 will be wiped. Under the action of centrifugal force, the head cleaning liquid will move to the position of the through hole 17, then enter the connecting tube 19 from the through hole 17, then enter the first square tube 21, and finally flow out from the liquid outlet 20, adding lens cleaning liquid to the lens 9, and the lens 9 is cleaned with a brush; when the cleaning is completed, the speed of the first motor 7 is increased to increase the centrifugal force, so that the sliding magnetic block 33 is further moved to the position of the second magnetic block 31. At this time, the first magnetic block 28 loses the force of the sliding magnetic block 33, and then it will be reset under the action of the corresponding first elastic member 18, that is, the first square tube 21 leaves the surface of the lens 9, the through hole 17 moves out of the liquid storage chamber 22, and the liquid outlet 20 is no longer The liquid will be discharged, and at this time, the second magnetic block 31 will be moved by the repulsive force of the sliding magnetic block 33, so that the second square tube 27 will overcome the force of the corresponding first elastic member 18 and move away from the water storage chamber 32. At this time, the scraper 25 will be attached to the lens 9. At the same time, the through hole 17 on the connecting pipe 19 corresponding to the second square tube 27 will enter the water storage chamber 32. Under the action of centrifugal force, the water in the water storage chamber 32 enters the connecting pipe 19 from the corresponding through hole 17, and then enters the second square tube 27, and finally flows out from the water outlet 26 to rinse the lens 9 with residual liquid. At the same time, the scraper 25 is used to clean the lens 9 of the residual liquid of the lens cleaning liquid. After cleaning, the first motor 7 stops rotating and the sliding magnetic block 33 moves. The moving magnetic block 33 loses the centrifugal force and is reset under the action of the second elastic member 29, and the second magnetic block 31 loses the force of the sliding magnetic block 33 and is also reset, that is, the second square tube 27 is also reset; finally, the moving assembly drives the cleaning assembly away from the lens 9 to complete the cleaning of the lens 9; in order to increase the centrifugal force exerted on the liquid in the liquid storage chamber 22 and the water storage chamber 32, a counterweight block 23 can be added to each chamber, and the counterweight block 23 is arranged at a position in each chamber away from the corresponding connecting pipe 19, so that the liquid is located between the counterweight block 23 and the connecting pipe 19. In this way, when the cleaning box 8 rotates to generate centrifugal force, the counterweight block 23 can also push the liquid close to the corresponding connecting pipe 19.

[0102] The mobile components include:

[0103] The screw rod 15 is rotatably arranged on the side of the mounting groove 10 .

[0104] The second motor 14 is fixedly disposed on the side top of the mounting groove 10 , and its output end is fixedly connected to the end of the screw rod 15 . The second motor 14 can drive the screw rod 15 to rotate.

[0105] Two screw rods 15 and two second motors 14 are provided, and are respectively located at two inner sides of the installation groove 10 .

[0106] The two ends of the bracket 6 are respectively threadedly connected to two screw rods 15. When the screw rods 15 rotate, the bracket 6 can be driven to move up and down, thereby driving the cleaning component to move up and down.

[0107] The cleaning assembly further comprises a first motor 7 , which is fixedly arranged in the middle of the bracket 6 , and an output end of the first motor 7 is fixedly connected to the middle of the cleaning box 8 .

[0108] Two slide grooves 13 are provided at the lower part of the housing 1 , and two sliders 34 are fixedly provided on the inner ring surface of the protective cover 12 . The two sliders 34 are connected by a connecting plate 36 , and the sliders 34 are slidably provided in the slide grooves 13 .

[0109] The transmission components include:

[0110] The chuck 16 is rotatably arranged on the housing 1 and is located in the mounting groove 10 and is higher than the lens 9. The chuck 16 is provided with a slot matching the cleaning box 8, and the cleaning box 8 can be inserted into the slot. When the lens 9 is not cleaned, the cleaning box 8 is located in the slot of the chuck 16.

[0111] The transmission part is arranged at the inner lower part of the housing 1 and is used to connect the chuck 16 and the connecting plate 36 .

[0112] The transmission part includes:

[0113] The first pulley 43 is fixedly connected to the chuck 16 , and the first pulley 43 is located inside the housing 1 .

[0114] The rotating shaft 40 is rotatably arranged at the inner lower part of the housing 1 .

[0115] The second pulley 41 is fixedly disposed on the inner end of the rotating shaft 40 , and the second pulley 41 is connected to the first pulley 43 via a synchronous belt 42 .

[0116] The gear 44 is fixedly disposed on the outer end of the rotating shaft 40 .

[0117] The rack 38 is fixedly disposed on the connecting plate 36 and meshedly connected with the gear 44 .

[0118] The transmission part also includes:

[0119] A limiting hole is provided on the second pulley 41 .

[0120] The electromagnetic rod 39 is fixedly arranged on the inner wall of the housing 1, and the telescopic rod of the electromagnetic rod 39 can be inserted into the limiting hole. In this state, the chuck 16 cannot rotate.

[0121] When the transmission assembly is in use, the cleaning box 8 is inserted into the slot and then rotated, thereby driving the chuck 16 to rotate. The rotation of the chuck 16 can drive the first pulley 43 to rotate, and then drive the second pulley 41 to rotate. Since the second pulley 41 and the gear 44 are installed on the same rotating shaft 40, the gear 44 will also rotate, and then drive the rack 38 to move up and down, thereby driving the connecting plate 36 to move up and down, and then driving the protective cover 12 to move up and down; when the protective cover 12 is in a state of opening the mounting slot 10, that is, when the overall position of the protective cover 12 is higher than the mounting slot 10, the electromagnetic rod 39 is energized, and the telescopic rod of the electromagnetic rod 39 overcomes the force of its return spring and is inserted into the limit hole to limit the second pulley 41. At this time, the entire transmission assembly and the protective cover 12 cannot move.

[0122] Also included is a reset component, which includes:

[0123] The slide bar 35 is vertically fixedly disposed at the inner lower part of the housing 1 .

[0124] The third elastic member 37 is arranged on the slide rod 35. Specifically, the third elastic member 37 adopts a spring. The third elastic member 37 is sleeved on the slide rod 35, one end of which is fixedly connected to the top end of the slide rod 35, and the other end is fixedly connected to the top surface of the connecting plate 36.

[0125] The middle portion of the connecting plate 36 is slidably connected to the sliding rod 35 , and the third elastic member 37 applies a downward force to the connecting plate 36 .

[0126] When it is necessary to close the mounting groove 10, the electromagnetic rod 39 can be directly powered off, so that the telescopic rod of the electromagnetic rod 39 leaves the limit hole under the action of its return spring, and the limit is released. Then the connecting plate 36 can move downward under the action of the third elastic member 37, so that the protective cover 12 moves down to close the mounting groove 10. This closing process is suitable for the case of battery failure. In addition, there is another closing method, that is, actively powering off the electromagnetic rod 39, after the limit is released, starting the first motor 7 to rotate, and then driving the connecting plate 36 to move downward through the transmission assembly. This closing process is controllable and will not cause a large impact. In normal use, this method can be used to control the opening and closing of the mounting groove 10.

[0127] Workflow: During normal flight shooting (such as Figure 1As shown in the figure), the protective cover 12 is in the open state, and the cleaning box 8 is located in the card slot of the chuck 16, which does not affect the normal shooting of the lens 9. When the lens 9 needs to be cleaned, the moving component drives the cleaning box 8 to move down and disengage from the card slot. When the cleaning box 8 is located directly in front of the lens 9, cleaning begins. After cleaning, the moving component drives the cleaning box 8 to re-enter the card slot to continue shooting. After shooting, the drone returns and lands, and then the support arm 3 and the propeller 2 are stored in the storage slot 4, and the protective cover 12 closes the installation slot 10. When closed, the electromagnetic rod 39 is actively powered off to release the limit, and then the first motor 7 is used to drive the cleaning box 8 to rotate slowly, and then the chuck 16 is driven to rotate, and then the connecting plate 36 is driven to rotate slowly under the power transmission of the transmission component. It slowly moves downward, and then the protective cover 12 slowly closes the installation slot 10; if the drone loses control during flight shooting, the drone attitude sensor will sense that the drone is out of control and will automatically cut off the power to the electromagnetic rod 39. After the limit is released, the cleaning component and the transmission component are used to drive the connecting plate 36 to move downward, and then the protective cover 12 closes the installation slot 10. When it falls to the ground out of control, the buffer component is used as a buffer to reduce the damage to the drone caused by direct impact with the ground; if the drone loses power due to battery failure during flight, the electromagnetic rod 39 will be cut off. After the limit on the second pulley 41 is released, the connecting plate 36 can be directly driven by the third elastic member 37 to move downward, and then the protective cover 12 closes the installation slot 10, so as to protect the lens 9.
