Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with a lens cleaning function. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently. Compared with manned aircraft, UAVs are often more suitable for tasks that are too "dull, dirty, or dangerous".

[0003] A search revealed Chinese patent CN202022376780.3, which discloses a drone with omnidirectional shooting capabilities, including the drone body. While it has the advantage of camera protection, it still has the following problems:

[0004] 1. It is inconvenient to clean the dust, impurities and dead insects attached to the camera lens surface, which will hinder the normal shooting of the camera;

[0005] 2. Even if a few lenses are cleaned by rotating the cleaning brush, impurities and insect corpses still adhere to the lens surface and are not thoroughly cleaned, resulting in poor cleaning effect. Utility Model Content

[0006] Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a drone with a lens cleaning function, mainly to solve the problem that it is inconvenient to clean dust, impurities, and insect corpses attached to the surface of the camera lens, which would hinder the normal shooting of the camera. Even if a few lenses are cleaned by rotating the cleaning brush, the cleaning effect is poor.

[0008] Technical solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A drone with lens cleaning function includes a drone body, a camera for taking pictures installed at the bottom of the drone body, a cleaning mechanism for cleaning the lens cover of the camera at the bottom of the drone body, a drive mechanism for swinging the cleaning mechanism at the bottom of the drone body, and a rinsing mechanism communicating with the cleaning mechanism at the bottom of the drone body and on the drive mechanism.

[0011] Furthermore, the cleaning mechanism includes a fixed plate fixedly connected to the bottom of the drone body, a rotating rod rotatably connected to the fixed plate, an arc-shaped hollow plate fixedly connected to one end of the rotating rod, a cleaning cotton brush fixedly connected to the inner surface of the arc-shaped hollow plate, and a liquid outlet hole opened on the arc-shaped hollow plate.

[0012] Furthermore, a second fixing plate is fixedly connected to the bottom of the drone body, and a rotating cylinder is rotatably connected to the second fixing plate. One end of the rotating cylinder is connected to an arc-shaped hollow plate, and a through hole is opened on the surface of the other end of the rotating cylinder.

[0013] Furthermore, the driving mechanism includes a turntable fixedly connected to one end of the rotating drum, a short rod fixedly connected to one side of the turntable, and a movable frame movably sleeved on the surface of the short rod.

[0014] Furthermore, a connecting plate is fixedly connected to the bottom of the drone body, and an electric telescopic rod is fixedly connected to the connecting plate. The telescopic end of the electric telescopic rod is fixedly connected to the surface of the moving frame.

[0015] Furthermore, the rinsing mechanism includes a liquid tank fixedly connected to the bottom of the drone body, a square rod fixedly connected to the moving frame, a cylinder slidably sleeved on the surface of the square rod, and a piston fixedly connected to one end of the square rod located in the inner cavity of the cylinder.

[0016] Furthermore, one end of the cylinder is connected to a one-way valve and a one-way valve, respectively. One end of the one-way valve is connected to a bend pipe, which extends through and into the inner cavity of the liquid tank. One end of the one-way valve is connected to a bend pipe. A circular shell is fitted onto the surface of the rotating cylinder through a sealed bearing. The circular shell is fixedly connected to one side of the fixed plate. One end of the bend pipe is connected to the circular shell.

[0017] Furthermore, a sealing gasket is fixedly connected to the piston, and a second connecting plate is fixedly sleeved on the cylinder, with the upper end of the second connecting plate fixedly connected to the bottom of the UAV body.

[0018] Furthermore, a heat sink is fixedly connected through the top of the liquid tank, and the heat sink is fixedly connected to the bottom of the drone body.

[0019] Beneficial effects

[0020] Compared with the prior art, this utility model provides a drone with lens cleaning function, which has the following beneficial effects:

[0021] 1. This utility model achieves full-coverage dynamic cleaning of the lens through an arc-shaped hollow plate and a reciprocating swing structure. The cleaning cotton brush swings back and forth to wipe, and the curvature radius design of the arc-shaped hollow plate improves the cleaning coverage, solves the technical problem of cleaning blind spots in traditional unidirectional rotating brushes, and reduces the amount of mosquito carcass residue.

[0022] 2. This utility model achieves precise metering and spraying of cleaning agent through a piston and square rod linkage liquid supply system. The electric telescopic rod drives the piston to form a certain pumping volume, which, together with several liquid outlet holes, forms an atomized cleaning agent spray layer, thereby improving the dissolution efficiency of stubborn stains and enhancing the cleaning effect compared to traditional dry brushing.

[0023] 3. This utility model achieves automated switching of cleaning actions through a moving frame and a turntable crank slider mechanism, converting linear motion into rotational oscillation, enabling the cleaning mechanism to switch between working mode and avoidance mode within a certain time, thus avoiding the problem of traditional external cleaning devices obstructing the shooting perspective.

[0024] 4. This utility model achieves zero-leakage operation of the dynamic liquid supply system through a sealed bearing-type rotating drum structure. The sealed bearing between the rotating drum and the shell adopts a double-stage fluororubber sealed bearing, which improves the sealing performance compared with the traditional rotary joint.

[0025] 5. This utility model achieves temperature control of the cleaning agent through a heat exchange system of heat sink and liquid tank. The aluminum heat sink conducts the waste heat of the drone motor to the liquid tank, maintaining the cleaning agent above 5°C even at -10°C, ensuring the fluidity of the cleaning agent and the effectiveness of its active ingredients at low temperatures.

[0036] Reference Figures 1-6A drone with lens cleaning function includes a drone body 100, a camera 200 for taking pictures installed at the bottom of the drone body 100, a cleaning mechanism 300 for cleaning the lens cover on the camera 200 at the bottom of the drone body 100, a drive mechanism 400 for swinging the cleaning mechanism 300 at the bottom of the drone body 100, and a rinsing mechanism 500 connected to the cleaning mechanism 300 at the bottom of the drone body 100 and on the drive mechanism 400.

[0037] Furthermore, the cleaning mechanism 300 includes a fixed plate 301 fixedly connected to the bottom of the drone body 100. A rotating rod 302 is rotatably connected to the fixed plate 301. An arc-shaped hollow plate 303 is fixedly connected to one end of the rotating rod 302. A cleaning cotton brush 304 is fixedly connected to the inner surface of the arc-shaped hollow plate 303. A liquid outlet hole 305 is opened on the arc-shaped hollow plate 303.

[0038] Specifically, the rotating rod 302 is rotatably connected to the fixed plate 301 via a bearing. The reciprocating rotation of the arc-shaped hollow plate 303 drives the reciprocating rotation of the cleaning brush 304 to clean the surface of the lens cover of the camera 200 on the bottom of the drone body 100, reducing dust and insect remains adhering to the lens cover surface. There are several liquid outlet holes 305. Through the setting of the liquid outlet holes 305, when the arc-shaped hollow plate 303 drives the cleaning brush 304 to reciprocate, the liquid outlet holes 305 discharge cleaning agent, which can improve the cleaning effect. When not in use, the cleaning brush 304 and the arc-shaped hollow plate 303 are suspended at a certain angle from the bottom of the drone body 100, so that the camera 200 is not affected when using it for shooting.

[0039] Furthermore, a fixing plate 306 is fixedly connected to the bottom of the drone body 100, and a rotating cylinder 307 is rotatably connected to the fixing plate 306. One end of the rotating cylinder 307 is connected to the arc-shaped hollow plate 303, and a through hole 308 is opened on the surface of the other end of the rotating cylinder 307.

[0040] Specifically, the rotating drum 307 is rotatably connected to the fixed plate 306 via a bearing. The rotating drum 307 is fixedly connected to and communicates with the arc-shaped hollow plate 303. There are several through holes 308. By setting the through holes 308, the communication between the circular shell 509 and the rotating drum 307 is ensured when the rotating drum 307 rotates. This allows the cleaning agent that enters the circular shell 509 through the bend pipe 508 to enter the rotating drum 307 when the rotating drum 307 rotates, and then enters the arc-shaped hollow plate 303 and is discharged from the liquid outlet 305.

[0041] Furthermore, the drive mechanism 400 includes a turntable 401 fixedly connected to one end of the rotating drum 307, a short rod 402 fixedly connected to one side of the turntable 401, and a movable frame 403 movably sleeved on the surface of the short rod 402.

[0042] Specifically, by moving the movable frame 403, the short rod 402 is acted upon, reciprocating and rotating within it, thereby causing the turntable 401 to rotate in both directions, which in turn causes the rotating drum 307 and the arc-shaped hollow plate 303 to rotate in both directions, thus enabling the cleaning brush 304 to rotate in both directions for cleaning operations.

[0043] Furthermore, a connecting plate 404 is fixedly connected to the bottom of the drone body 100, and an electric telescopic rod 405 is fixedly connected to the connecting plate 404. The telescopic end of the electric telescopic rod 405 is fixedly connected to the surface of the moving frame 403.

[0044] Specifically, there are two connecting plates 404. The connecting plates 404 are fixedly sleeved on the surface of the electric telescopic rod 405. By controlling the extension and retraction of the electric telescopic rod 405, the moving frame 403 can be moved back and forth, thereby causing the short rod 402 and the turntable 401 to rotate back and forth, thus causing the rotating cylinder 307, the rotating rod 302 and the arc-shaped hollow plate 303 to rotate back and forth.

[0045] Furthermore, the rinsing mechanism 500 includes a liquid tank 501 fixedly connected to the bottom of the drone body 100, a square rod 502 fixedly connected to the moving frame 403, a cylinder 503 slidably sleeved on the surface of the square rod 502, and a piston 504 fixedly connected to one end of the square rod 502 located in the inner cavity of the cylinder 503.

[0046] Specifically, the cylinder 503 and piston 504 form a syringe-like structure. When the moving frame 403 drives the square rod 502 to move back and forth, the piston 504 moves back and forth inside the cylinder 503. Then, under the action of one-way valve 505 and one-way valve 506, the cleaning agent in the liquid tank 501 is drawn into the cylinder 503 through the bend pipe 507, and then discharged into the cylindrical shell 509 through the bend pipe 508. After that, it enters the arc-shaped hollow plate 303 through the through hole 308 and the rotating cylinder 307, and is discharged from the outlet hole 305. With the power of driving the arc-shaped hollow plate 303 and the cleaning brush 304 to rotate, the cleaning agent in the liquid tank 501 is discharged from the arc-shaped hollow plate 303, and the cleaning operation is carried out simultaneously.

[0047] Furthermore, one end of the cylindrical 503 is connected to a one-way valve 505 and a one-way valve 506, respectively. One end of the one-way valve 505 is connected to a bend 507, one end of which extends through and into the inner cavity of the liquid tank 501. One end of the one-way valve 506 is connected to a bend 508. A circular shell 509 is fitted on the surface of the rotating cylinder 307 through a sealed bearing. The circular shell 509 is fixedly connected to one side of the fixed plate 306. One end of the bend 508 is connected to the circular shell 509.

[0048] Specifically, by setting one-way valve 505 and one-way valve 506, when piston 504 reciprocates inside cylinder 503, the cleaning agent in liquid tank 501 enters cylinder 503 through bend 1 507 and then enters circular shell 509 through bend 2 508, without backflow. The cleaning agent in liquid tank 501 is smoothly drawn out and discharged from outlet hole 305. Through the sealed bearing, rotating drum 307 can rotate on circular shell 509 and ensures sealing, so that the cleaning agent in circular shell 509 will not leak and smoothly enters rotating drum 307 through through hole 308.

[0049] Furthermore, a sealing gasket 510 is fixedly connected to the piston 504, and a connecting plate 511 is fixedly sleeved on the cylinder 503. The upper end of the connecting plate 511 is fixedly connected to the bottom of the UAV body 100.

[0050] Specifically, through the setting of the sealing gasket 510, after use, it moves with the piston 504 and comes into close contact with the inner wall of the one-way valve connected to the cylinder 503, thereby closing the valve and preventing the cleaning agent in the liquid tank 501 from leaking. There are two connecting plates 511, which fix and support the cylinder 503.

[0051] Furthermore, a heat sink 600 is fixedly connected to the top of the liquid tank 501, and the heat sink 600 is fixedly connected to the bottom of the drone body 100.

[0052] Specifically, there are several heat sinks 600, which transfer heat to the cleaning agent in the liquid tank 501, thereby dissipating heat from the drone body 100 during operation. In a low-temperature environment, they also transfer heat to the cleaning agent in the liquid tank 501, ensuring that the cleaning agent is at a certain temperature, which makes the cleaning effect better when it is discharged.

[0053] The working principle of this utility model:

[0054] S1. When it is necessary to clean the surface of the camera 200, control the extension and retraction of the electric telescopic rod 405, so that it drives the moving frame 403 to move back and forth, thereby driving the square rod 502, piston 504 and sealing gasket 510 to move back and forth, so that the piston 504 moves back and forth inside the cylinder 503.

[0055] S2. Then, under the action of one-way valve 505 and one-way valve 506, the cleaning agent in the liquid tank 501 is drawn into the cylinder 503 through the bend pipe 507, and then discharged into the round shell 509 through the bend pipe 508. Then, it enters the arc-shaped hollow plate 303 through the through hole 308 and the rotating cylinder 307, and is discharged from the liquid outlet 305.

[0056] S3, the reciprocating movement of the moving frame 403 causes the short rod 402 to rotate reciprocally, which in turn causes the turntable 401 to rotate forward and backward, thereby causing the rotating drum 307 and the arc-shaped hollow plate 303 to rotate forward and backward, realizing the cleaning cotton brush 304 to rotate forward and backward for cleaning operation. At the same time, the sprayed cleaning agent works together with the cleaning cotton brush 304 to better clean the lens cover of the camera 200.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
