Description

Technical Field

[0001] The present invention relates to the relevant field of civil aircraft, and in particular to a UAV with high protection and visual field expansion performance. Background Art

[0002] In today's life, in order to obtain a wider and better photographic perspective, people usually use drones equipped with cameras for aerial photography. In order to facilitate aerial photography, most traditional cameras are installed at the center of the drone. However, most drones on the market are currently equipped with a U-shaped bracket at the bottom for support, which will block the photographic perspective when taking pictures.

[0003] In addition, when a drone malfunctions and crashes, due to the bottom-mounted characteristics of the camera, the camera part will hit the ground first, making it very easy to break, causing huge economic losses. Summary of the invention

[0004] In order to overcome the defects of the above-mentioned technology, the present invention proposes a drone with high protection and viewing angle expansion performance.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] A drone with high protection and extended viewing angle performance includes a body and a general assembly plate arranged below the body, and a hollow groove is provided in the center of the general assembly plate. The hollow groove facilitates the extension of a camera probe, and the general assembly plate plays a certain protective role.

[0007] Two sets of transverse rods are installed at the bottom of the assembly plate through bearings, and each set of transverse rods is connected to a U-shaped bracket through a key; each U-shaped bracket is equipped with a reinforcement structure; the transverse rod is equipped with a transfer control component; and the assembly plate is also connected to a camera protection component. Under normal circumstances, the two U-shaped brackets support the entire drone. The transfer control component is used to control the rotation of the U-shaped bracket to eliminate obstructions to aerial photography. The reinforcement structure is used to reinforce the position of the U-shaped bracket to prevent it from loosening. The camera protection component protects the camera when the drone falls.

[0008] The reinforcement structure includes a hydraulic cylinder mounted on the assembly plate and a drive seat connected to the hydraulic cylinder, and the drive seat is provided with a slot adapted to the U-shaped bracket. That is, in normal state, the vertical part of the U-shaped bracket is engaged in the slot, thereby playing a role in fixing the state.

[0009] Preferably, the assembly plate is provided with a short bottom groove for slidingly mounting the drive seat.

[0010] Preferably, the indexing control assembly includes a cylinder mounted on the assembly plate, an auxiliary block connected to the cylinder, a rack welded to the auxiliary block, and two pinions meshing with the rack; each pinion is mounted on a corresponding transverse rod. That is, through the gear rack transmission, the two U-shaped brackets can be controlled to rotate, thereby avoiding blocking the photographic angle.

[0011] The beneficial effects of the present invention are:

[0012] The present invention is easy to use, and can achieve the effect of automatically expanding the aerial photography angle by controlling the rotation of the U-shaped bracket. It can also prevent the camera from being damaged by controlling the descent mode of the general assembly plate when the drone falls, and has a good protection effect.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0024] like Figure 1 As shown, a drone with high protection and viewing angle expansion performance includes a body 1 and a general assembly board 2 arranged below the body 1, and a hollow groove 2a is provided in the center of the general assembly board 2. The hollow groove 2a facilitates the extension of the camera probe, and the general assembly board 2 plays a certain protective role.

[0025] like Figures 1 to 3 As shown, two groups of transverse rods 3 are installed at the bottom of the assembly plate 2 through bearings, and each group of transverse rods 3 is connected to a U-shaped bracket 4 through a key; each U-shaped bracket 4 is equipped with a reinforcement structure; the transverse rod 3 is equipped with a transfer control component; the assembly plate 2 is also connected to a camera protection component. Under normal circumstances, the two U-shaped brackets 4 support the entire drone. The transfer control component is used to control the rotation of the U-shaped bracket 4 to eliminate obstructions to aerial photography. The reinforcement structure is used to reinforce the position of the U-shaped bracket 4 to prevent it from loosening. The camera protection component protects the camera when the drone falls.

[0026] like Figure 3 As shown, the reinforcement structure includes a hydraulic cylinder 5 mounted on the assembly plate 2 and a drive seat 6 connected to the hydraulic cylinder 5, and the drive seat 6 is provided with a slot 6a adapted to the U-shaped bracket 4. That is, in normal state, the vertical part of the U-shaped bracket 4 is engaged in the slot 6a, thereby playing a role in fixing the state.

[0027] like Figure 3 As shown, the assembly plate 2 is provided with a short bottom groove 2c for slidingly mounting the drive seat 6. The above is a conventional design of the sliding structure.

[0028] like Figures 2 to 4As shown, the indexing control assembly includes a cylinder 7 mounted on the assembly plate 2, an auxiliary block 8 connected to the cylinder 7, a rack 9 welded to the auxiliary block 8, and two pinions 10 meshing with the rack 9; each pinion 10 is mounted on a corresponding transverse rod 3. That is, through the gear rack transmission, the two U-shaped brackets 4 can be controlled to rotate, thereby avoiding blocking the photographic angle.

[0029] like Figure 3 As shown, the assembly plate 2 is provided with a long bottom groove 2b for slidingly mounting the rack 9. The above is a conventional design of the sliding structure.

[0030] like Figure 1 and Figure 6 As shown, the camera protection device includes a bracket seat 11 installed at the bottom of the body 1, a center seat 12 fixedly installed at the bottom of the bracket seat 11, and a spring 13 connected to the center seat 12 and the assembly plate 2; a reference mounting block 14 is installed in the middle of the center seat 12. The reference mounting block 14 is used to install the camera. Under normal conditions, the camera probe extends downward to the bottom of the hollowed groove 2a.

[0031] like Figure 2 and Figure 5 As shown, inclined surfaces 2d are provided at the four corners of the assembly board 2, and a protection control component adapted to the inclined surfaces 2d is installed on the center seat 12. The protection control component is used to control the lifting of the assembly board 2, thereby protecting the probe.

[0032] like Figure 2 , Figure 7 as well as Figure 8 As shown, the protection control assembly includes four linear guide rails 15 installed on the center seat 12, a composite sliding seat 16 slidably installed on each linear guide rail 15, and an L-shaped long rod 17 connected to each composite sliding seat 16; the composite sliding seat 16 is provided with a reverse inclined surface 16a adapted to the inclined surface 2d. The sliding of the composite sliding seat 16 and the push-movement of the inclined surface can make the assembly plate 2 rise and fall.

[0033] like Figure 7 As shown, a circular guide rail 12a is provided on the outer side of the center seat 12, and an annular snap ring 18 is slidably mounted on the circular guide rail 12a. The annular snap ring 18 is provided with four circular arc grooves 18a that slide and hinge with the corresponding L-shaped long rods 17. That is, the annular snap ring 18 can slide in a rotating manner, and the rotation of the circular arc groove 18a can drive all the above-mentioned composite sliding seats 16 to synchronously slide in opposite directions or toward each other relative to the center position of the center seat 12.

[0034] like Figure 7As shown, the outer side of the annular snap ring 18 is provided with a circle of gear teeth 18b, and the protection control assembly also includes a pinion 19 meshing with the gear teeth 18b, and the pinion 19 is connected to a motor 20 fixedly mounted on the bottom end of the body 1. That is, the rotation of the annular snap ring 18 is controlled by gear transmission.

[0035] Before use, the camera only needs to be installed at the reference installation block 14 and the camera head is extended below the assembly plate 2 .

[0036] When the UAV is flying in the air for aerial photography, the hydraulic cylinder 5 can be used to pull the driving seat 6 to remove the limit on the U-shaped bracket 4, and then the cylinder 7 can be used to push and pull the auxiliary block 8 to rotate the U-shaped bracket 4 to a horizontal state, thereby removing the obstruction to the camera's viewing angle.

[0037] When the drone malfunctions and falls, the motor 20 can be driven to rotate, causing the annular retaining ring 18 to rotate counterclockwise, so that all the composite sliding seats 16 can slide synchronously relative to the center position of the center seat 12, and under the action of elastic force and inclined surfaces, the entire assembly plate 2 drops to the bottom of the camera head of the camera, so that when it falls to the ground, the assembly plate 2 can prevent the camera head from being broken.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
