Description

Technical Field

[0001] The present application relates to the field of aircraft technology, and in particular to an unmanned aerial photography device. Background Art

[0002] Drone aerial photography is an important direction in current drone applications. After a camera is mounted under the drone, the camera can be used to shoot targets on the ground or in the air during flight, and the obtained images or video data are analyzed by ground equipment.

[0003] In actual applications, there are many requirements for aerial photography. For example, different occasions have different requirements for resolution, frame rate, optical band, etc., and the same camera can only meet one or a few requirements. When the requirements change, the camera usually needs to be replaced. The camera is installed on the drone. If the drone is replaced along with the camera, the cost will be very high. Therefore, aerial photography drones basically adopt a detachable camera structure, such as CN201820344422.4 and CN201720361900.8.

[0004] However, after the camera is disassembled, one problem is the protection of the camera lens. If the disassembled camera is directly placed in a lens bag or other device, the lens may be worn, thereby affecting the normal use of the camera. Although the above patent discloses the detachable structure of the camera, it does not involve the protection of the camera lens. Utility Model Content

[0005] The embodiment of the present application provides a drone aerial photography device to solve the problem in the prior art that the disassembled camera is not effectively protected.

[0011] In a possible implementation, an elastic member is disposed between the slider and the connecting rod, and the elastic member provides elastic force for the end of the protective shell close to the camera to rotate in a direction away from the camera.

[0012] In a possible implementation, the protective shell is provided with an insertion tube on the end surface close to the camera, and an insertion rod is provided at the edge of the blocking cover, and the insertion rod is rotatably inserted into the insertion tube.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Figure 1-5 The present invention provides a schematic diagram of a drone aerial photography device according to an embodiment of the present invention. The present invention provides a drone aerial photography device according to an embodiment of the present invention, including a connecting portion 100, a rotating portion 110 and a camera 120 connected in sequence, and also including:

[0026] The sliding assembly 101 is arranged on the side of the connecting portion 100;

[0027] The protective shell 130 includes at least two protective shells 130, each of which is slidably connected to a sliding component 101. A blocking cover 131 is provided at one end of the protective shell 130, and a convex edge 132 is provided at the other end. When the protective shell 130 slides to the end close to the camera 120, the blocking cover 131 blocks the camera 120. When the protective shell 130 slides to the end away from the camera 120, the blocking cover 131 opens to expose the camera 120, and is clamped in the connecting groove 210 provided on the side of the connecting column 200 of the drone by the convex edge 132.

[0028] Exemplarily, a first driving motor is disposed inside the connecting portion 100, and a driving shaft of the first driving motor is connected to the rotating portion 110, so that the rotating portion 110 rotates in a horizontal plane under the control of the first driving motor. A second driving motor is disposed inside the rotating portion 110, and a driving shaft of the second driving motor is connected to the camera 120, so that the camera 120 rotates in a vertical plane under the control of the second driving motor. With these two driving motors, the effect of rotating the camera 120 in any direction is achieved.

[0029] Furthermore, the top of the connecting part 100 and the bottom end of the connecting column 200 at the bottom of the drone are respectively provided with matching interfaces and connectors. When the flange 132 on the protective shell 130 is engaged with the connecting groove 210 on the connecting column 200, the connector will also be plugged into the interface, so that the aerial photography device and the drone can achieve electrical and communication connection.

[0030] exist Figure 1-3 In the embodiment, there are two protective shells 130, and both protective shells 130 are similar to semi-cylindrical shells. Therefore, when the protective shells 130 are closed, a relatively closed structure can be formed to surround the connecting portion 100 and the rotating portion 110, especially the camera 120, to achieve a better protective effect. It should be understood that in other embodiments, the number of protective shells 130 can be three, four, etc. When these numbers are used, the sizes of the protective shells 130 can be the same or different. Regardless of whether they are the same or different sizes, all protective shells 130 need to form a cylindrical structure after being spliced ​​together to provide a good protective effect for the camera 120.

[0031] In the closed state, the cover 131 can be manually rotated to a state of being close to the camera 120, and at least two covers 131 can be spliced ​​together to completely block the camera 120. When it is necessary to open, the cover 131 can be manually rotated to a state parallel to the side of the protective shell 130 to expose the camera 120, and then at least two protective shells 130 are slid upward synchronously. After the protective shell 130 is slid to the highest point, the convex edge 132 is opposite to the connection groove 210. At this time, the protective shell 130 is rotated to a certain angle, and the convex edge 132 can be inserted into the connection groove 210, so that the aerial photography device and the drone are stably connected together.

[0032] In a possible embodiment, the sliding assembly 101 includes: a connecting rod 102, which is fixedly arranged on the side of the connecting part 100; a slider 104, which is rotatably connected to the connecting rod 102, and the cross-section of the slider 104 is rectangular. A sliding groove 133 is axially arranged on the inner side surface of the protective shell 130, and the slider 104 is slidably inserted in the sliding groove 133.

[0033] For example, when a cube or rectangular plate-shaped slider 104 is used, the slide groove 133 should be equal to the length or width of the slider 104, and the cross section of the slide groove 133 is preferably T-shaped, so that the slider 104 will not slide out of the slide groove 133. After using the slider 104 and the slide groove 133 of the above shape, the protective shell 130 can slide relative to the connecting rod 102 and can also rotate relative to it, so that the flange 132 can be inserted into the connecting groove 210.

[0034] Specifically, in order to ensure that the protective shell 130 can both slide and rotate, and ultimately achieve the effect of the flange 132 and the connecting groove 210 being snapped together, in the embodiment of the present application, each protective shell 130 corresponds to one or two connecting rods 102. When two connecting rods 102 are used, it is necessary to ensure that the axes of the two connecting rods 102 coincide with each other. Regardless of whether it is one or two connecting rods 102, they need to be installed at an angle relative to the outer side surface of the connecting part 100, that is, the angle between the connecting rod 102 and the connecting part 100 is not 90°, and the specific angle needs to be adjusted according to the setting position of the connecting rod 102, so that the protective shell 130 can snap into the flange 132 in the connecting groove 210 after rotation.

[0035] Furthermore, a clamping head 103 is provided at the end of the connecting rod 102, and the diameter of the clamping head 103 is larger than that of the connecting rod 102. A clamping slot 105 is provided on the side of the slider 104, and the diameter of the opening of the clamping slot 105 matches that of the connecting rod 102, and the diameter inside the clamping slot 105 matches that of the clamping head 103. After adopting the structure of the clamping head 103 and the connecting rod 102, the two will form a T-shaped structure, and after the T-shaped clamping slot 105 is provided on the slider 104, it can be ensured that the clamping head 103 can be stably rotated and inserted into the clamping slot 105, and will not slide out of the clamping slot 105.

[0036] Furthermore, an elastic member is provided between the slider 104 and the connecting rod 102, and the elastic member provides elastic force for the end of the protective shell 130 close to the camera 120 to rotate in a direction away from the camera 120. The elastic member is preferably a torsion spring, which is wound on the outside of the clamping head 103. Under the action of the elastic force, even if the protective shell 130 is closed, the convex edge 132 will be pressed against the side of the connecting part 100. Once the protective shell 130 is slid to the highest point, the protective shell 130 will immediately rotate and make the convex edge 132 clamped in the connecting groove 210, thereby improving the stability of the connection between the protective shell 130 and the connecting column 200.

[0037] In a possible embodiment, the protective shell 130 is provided with an insertion tube on the end surface close to the camera 120 , and the edge of the blocking cover 131 is provided with an insertion rod, which is rotatably inserted into the insertion tube.

[0038] For example, the outer diameter of the insertion rod is comparable to the inner diameter of the insertion tube. When the insertion rod is inserted into the insertion tube, there will be a certain friction between the two. It is precisely because of the existence of friction that the blocking cover 131 can remain in a closed or open state after being rotated into place and will not rotate at will.

[0039] In a possible embodiment, the convex edge 132 and the connecting groove 210 are provided with a first attraction unit that attracts each other.

[0040] Exemplarily, the first attraction unit can use magnet blocks arranged in pairs. After the pair of magnet blocks are installed, when the flange 132 and the connecting groove 210 are engaged, the opposite magnetic poles of the pair of magnet blocks at the corresponding positions are arranged relative to each other to achieve an attraction effect. Of course, the first attraction unit can also use a magnet block and a ferromagnetic metal block to cooperate with each other, in which case there is no requirement for the direction of the magnet block. When the flange 132 and the connecting groove 210 are engaged, the first attraction unit attracts each other, which plays a role in strengthening the stability of the protective shell 130 and the connecting column 200.

[0041] In a possible embodiment, two adjacent convex edges 132 are provided with second attraction units for attracting each other at their ends close to each other.

[0042] For example, the second attraction unit can adopt the same structure and setting method as the first attraction unit, that is, a magnet block or a magnet block and a ferromagnetic metal block that attract each other can be used to cooperate with each other. The second attraction unit can enhance the stability of the connection between at least two protective shells 130, and further enhance the stability of the connection between the protective shell 130 and the connecting column 200.

[0043] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
