Description

Technical Field

[0001] This utility model relates to the field of aerial photography equipment technology, and in particular to an easily detachable drone aerial photography equipment. Background Technology

[0002] A drone is an unmanned aircraft controlled by radio remote control, program control, or an autonomous intelligent system. A drone aerial photography device is a system mounted on a drone for shooting and transmitting images. The core component includes a camera, and the camera is equipped with a gimbal.

[0003] A search revealed that utility model patent CN221163384U discloses an easily detachable drone aerial photography device, relating to the field of aerial photography device technology. The device includes: a mounting platform; a mounting sleeve, one end of which is set on the mounting platform, and a mounting cavity within the mounting sleeve; wherein a camera body is housed within the mounting cavity; and a fixing member, which is mounted on the mounting sleeve and located around the mounting cavity, securing the camera body within the cavity. By rotating a rotating block, the rotating block drives the fixing screws to rotate, and multiple fixing screws engage with multiple fixing threaded holes, causing the fixing pads on the multiple fixing screws to install and fix the camera body within the mounting cavity, thereby improving the stability of the camera body during aerial photography and facilitating its use on the drone. Conversely, removing the camera body from the mounting cavity facilitates its replacement and maintenance.

[0004] In the aforementioned disclosed structure, the camera body is placed in the mounting cavity of the mounting sleeve, and multiple fixing screws are required to install and fix the camera body in the mounting cavity. However, existing aerial cameras often need to be used in conjunction with a gimbal to ensure stability, which results in their shape not being a regular shape that can be placed in the mounting sleeve, and the mounting sleeve restricts their shooting angle. At the same time, the use of multiple fixing screws requires the staff to disassemble and install multiple screws during the assembly and disassembly process, which increases the complexity of the work and affects the work efficiency. Utility Model Content

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Reference Figures 1-5A detachable drone aerial photography device includes a main body 101, which comprises a gimbal frame 102 and a camera. A drone body 1 is mounted on top of the main body 101. Multiple legs are fixed to the bottom of the drone body 1. A frame sleeve 2 is fixed to the top of the gimbal frame 102. The gimbal frame 102 has multiple axes and multiple brushless motors. Various sensors are installed on the gimbal frame 102. Multiple outward-expanding plates 201 are fixed to the bottom of the drone body 1. The inner wall of each outward-expanding plate 201 has threaded grooves, and the circumference of each outward-expanding plate 201 fits against the inner wall of the frame sleeve 2. The inner wall is threaded with an auxiliary expansion pin 202. The outer expansion piece 201 is fixed to the inner wall of the frame sleeve 2 by the extrusion pressure of the auxiliary expansion pin 202. The auxiliary expansion pin 202 is screwed into the outer expansion piece 201, causing the outer expansion piece 201 to undergo elastic deformation and expand outward. The outer expansion piece 201 presses against the frame sleeve 2, thus fixing the two with pressure. The structure is simple and easy to install, reducing the complexity of disassembly and assembly. It can directly fix the gimbal frame 102 of the aerial photography main body 101 to the bottom of the drone main body 1, giving the gimbal frame 102 a large range of motion and maximizing the camera's shooting angle.

[0028] The bottom of the drone body 1 is fixed with a mounting base 3. Multiple outward expansion pieces 201 are fixed in a circumferential array at the bottom of the mounting base 3. Deformation slots 302 are formed between the multiple outward expansion pieces 201. The distance between the deformation slots 302 is not less than three millimeters. The bottom of the outward expansion piece 201 is fixed with a biting foot 301. By setting the biting foot 301, the frame sleeve 2 is prevented from slipping to the bottom of the outward expansion piece 201. At the same time, the deformation slot 302 gives the outward expansion piece 201 a larger deformation space, which improves the pressure fixation effect between the outward expansion piece 201 and the frame sleeve 2.

[0029] An expansion member 4 is fixed at the bottom of the auxiliary expansion pin 202. The diameter of the expansion member 4 is larger than the diameter of the threaded groove of the auxiliary expansion pin 202. The expansion member 4 further increases the pressure of the auxiliary expansion pin 202 on the outer expansion piece 201, and increases the expansion degree of the outer expansion piece 201, especially at the bottom. This greatly increases the pressure fixing effect between the frame sleeve 2 and the outer expansion piece 201, while preventing the frame sleeve 2 from slipping off the surface of the outer expansion piece 201.

[0030] The top edge of the expansion member 4 is set as the top arc surface 5, and the bottom inner circumferential edge of the outer expansion piece 201 is set as the bottom arc surface 501. When the expansion member 4 and the outer expansion piece 201 come into contact through the top arc surface 5 and the bottom arc surface 501, the arc surfaces can form a guide to prevent the squeezing damage caused by hard contact between the two and improve their service life.

[0031] A reinforcing rib 6 is fixed to the top of the biting foot 301. One side of the reinforcing rib 6 is fixed to the outer circumferential surface of the outer expansion piece 201. The reinforcing rib 6 increases the fixing effect between the biting foot 301 and the outer expansion piece 201, preventing the biting foot 301 and the outer expansion piece 201 from breaking due to the pressure of gravity on the frame sleeve 2, and improving the service life of the biting foot 301.

[0032] The top of the interlocking foot 301 is provided with a top slope 7, and the surface of the top slope 7 is provided with anti-slip grooves in a linear array. The grooves are oriented towards the auxiliary expansion nail 202. The top edge of the inner circumference of the sleeve 2 is provided with a bottom arc surface 701. The top slope 7 and the bottom arc surface 701 increase the distance of the outward expansion of the outer expansion piece 201, preventing the top of the interlocking foot 301 from contacting the bottom of the sleeve 2 too early, which would affect the degree of deformation of the outer expansion piece 201 and cause the pressure between the two to be too small, thus affecting the fixing effect.

[0033] A clip 8 is fixed to the outer periphery of the frame sleeve 2. A deformation groove 801 is formed on the inner wall of the clip 8 near the frame sleeve 2. Multiple stabilizing members 9 are fixed to the outer periphery of the clip 8. One side of the stabilizing member 9 is fixed to the outer periphery of the frame sleeve 2. By installing the clip 8, when the aerial photography main body 101 is removed, the auxiliary expansion pin 202 can be locked in the clip 8 for easy installation and to prevent loss. The deformation groove 801 prevents cracks from appearing when the clip 8 is deformed. The stabilizing member 9 not only improves the fixing effect between the frame sleeve 2 and the clip 8, but also increases the rebound ability of the clip 8.

[0034] The working principle of this utility model is as follows: The operator fixes the mounting base 3 to the bottom of the drone body 1. When the operator needs to install the aerial photography main body 101 onto the drone body 1, the top sleeve 2 of the gimbal frame 102 is placed around the outer expansion piece 201. Then, auxiliary expansion pins 202 are screwed into the holes formed at the bottom of the multiple outer expansion pieces 201, causing the outer expansion pieces 201 to elastically deform and expand outwards. This causes the outer expansion pieces 201 to press against the sleeve 2, thus fixing the two with pressure. The interlocking feet 301 prevent the sleeve 2 from slipping off the bottom of the outer expansion pieces 201. Simultaneously, the deformation slot 302 provides a larger deformation space for the outer expansion pieces 201, improving the pressure fixing effect between the outer expansion pieces 201 and the sleeve 2. The expansion member 4 further increases the pressure of the auxiliary expansion pins 202 on the outer expansion pieces 201, increasing the expansion degree of the outer expansion pieces 201, especially at the bottom. This greatly increases the pressure fixing effect between the sleeve 2 and the outer expansion pieces 201, while preventing the sleeve 2 from slipping off the outer expansion pieces 201. The surface slippage, the top arc surface 5 and the bottom arc surface 501 of the piece enable the expansion piece 4 and the outer expansion piece 201 to contact each other through the arc surface to form a guide, preventing the squeezing damage caused by hard contact between the two. The reinforcing ring rib 6 increases the fixing effect between the biting foot 301 and the outer expansion piece 201, preventing the biting foot 301 and the outer expansion piece 201 from breaking due to the pressure of gravity on the frame 2. When the staff needs to remove the aerial photography body 101, they only need to screw the auxiliary expansion nail 202 out of the outer expansion piece 201. The screwed-out auxiliary expansion nail 202 can be locked in the nail clip 8 for easy use by the staff during subsequent installation and to prevent loss. The deformation groove 801 prevents cracks from appearing when the nail clip 8 deforms. The stabilizing piece 9 improves the fixing effect between the frame 2 and the nail clip 8, while increasing the rebound ability of the nail clip 8. By gently pinching the outer expansion piece 201 to make it gather towards the center, the frame 2 can slide out from the outer peripheral surface of the outer expansion piece 201 to complete the disassembly.
