Description

Technical Field

[0001] The invention belongs to the technical field of aerial cameras, and in particular relates to a shockproof aerial camera housing. Background Art

[0002] Drone aerial photography technology uses drones as aerial remote sensing platforms and uses camera technology to capture aerial image data. Drone aerial images have the advantages of large scale and intelligence, and are particularly suitable for obtaining aerial images of strip areas such as roads, rivers, and coastlines. In addition, drones are less restricted by site restrictions for takeoff and landing, and are easier to transfer. They are also more stable and safer. In recent years, with the development of remote-controlled drones, drone aerial photography has become very popular and has a wide range of uses, involving many fields.

[0003] In the prior art, drones install aerial cameras on gimbals and use the rotation function of the gimbals to adjust the shooting angle. However, when drones carry aerial cameras to shoot images, the drones may shake due to some external factors or their own factors, causing the camera to shake. This shaking directly affects the stability of the lens, and on the other hand, long-term or severe shaking affects the stability of the internal components of the camera, causing the captured images to be blurred and sometimes a temporary black screen, greatly affecting the quality of the captured images. Although in order to solve the above problems, people have installed gimbal stabilizers on drones to stabilize the gimbals, but this only reduces the shaking from one aspect, while ignoring the stability of the aerial camera itself; secondly, due to the difference between the air environment and the ground environment, the shell and internal components of the aerial camera are easily damaged and affected by long-term use. Summary of the invention

[0004] In view of this, in order to solve the technical problem in the prior art that aerial cameras are prone to shaking, which affects the imaging quality, and further improve the adaptability of aerial cameras to differences in ground and air environments, the present invention provides a shockproof aerial camera housing.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows.

[0006] The housing of a shockproof aerial camera comprises a front housing and a rear housing, wherein the front housing is composed of a front plate, which is a square plate, and a through hole is provided on the front housing, and a bushing for fixing a lens is provided at the through hole, and a gasket is provided between the bushing and the lens, and the rear housing is composed of an upper plate, a lower plate, a left plate, a right plate and a rear plate, and is a square box with a front opening, and the opening matches the size of the front plate and can be closed by the front plate, and after closing, the front housing and the rear housing form a closed square box;

[0007] The front plate and the back plate are multi-layer structures, each consisting of a protective layer, a main plate, a buffer stabilization layer and a rubber layer arranged in sequence from the outside to the inside;

The inner surface of the rubber layer of the front plate is in extrusion contact with the outer surface of the front circuit board of the aerial camera, and the inner surface of the rubber layer of the rear plate is in extrusion contact with the outer surface of the rear circuit board of the aerial camera.

[0011] The buffer stabilization layer includes a plurality of connecting columns and a plurality of filling balls. The connecting columns are hollow cylinders with openings at both ends, one end of which is fixedly connected to the main board and the other end of which is fixedly connected to the rubber layer. The length of the connecting columns is 1200-1500 microns. The material of the connecting columns is polyurethane rubber with a hardness of Shore A75-80. The filling balls are filled in the gaps formed by the main board, the connecting columns and the rubber layer. The filling balls are water-absorbing and moisture-proof fiber balls, and the diameter of the filling balls is greater than the length of the connecting columns.

[0012] Furthermore, a notch is provided on the left plate or the right plate for leading out the connector.

[0013] Furthermore, the left plate or the right plate is provided with a mounting hole for connecting to the drone.

[0014] Furthermore, the material of the mainboard is D5100, D7000 or D800.
