Description

Technical Field

[0001] The utility model belongs to the technical field of fisheye lenses for unmanned aerial vehicles, and in particular relates to a fisheye lens for unmanned aerial vehicles. Background Art

[0002] A fisheye lens is an extreme wide-angle lens with unique imaging characteristics and a wide range of application scenarios. Its viewing angle is very wide, usually reaching or even exceeding 180 degrees, which enables it to capture extremely wide scenes, giving people a strong visual impact and exaggerated perspective effect.

[0003] Generally, the fisheye lens on a drone is installed at the bottom of the drone. When installing the fisheye lens on the drone, various tools are needed, which is troublesome to install. Drones are generally used outdoors, and personnel may forget to bring tools, which makes it impossible to install the fisheye lens. In addition, the fisheye lens on a drone is generally exposed to the outside world. When the drone is not in use, dust will fall on the fisheye lens for a long time, thereby affecting the clarity of the fisheye lens. In view of this, we propose a fisheye lens for a drone. Utility Model Content

[0004] The purpose of the utility model is to provide a fisheye lens for a drone to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a fisheye lens for a drone, comprising:

[0006] A drone body, wherein a mounting groove is provided at the bottom of the drone body, a sliding plate is slidably installed in the mounting groove, a plurality of limit rods are fixedly installed on the inner wall of the mounting groove and located on one side of the sliding plate, a spring is sleeved on each of the limit rods, and a clamping block is clamped and installed in the mounting groove and located on the other side of the sliding plate;

[0007] A protective shell, the protective shell is fixedly mounted on the bottom of the block, a placement slot is provided in the protective shell, a fisheye lens body is fixedly mounted in the placement slot, a rotating rod is symmetrically mounted on one side of the protective shell, a sealing plate is fixedly mounted on the rotating rod, one side of the sealing plate is in contact with one side of the protective shell, and a torsion spring is sleeved on the rotating rod;

[0008] Two limiting components, both of which are located in the protective shell and are used to limit the two rotating rods respectively.

[0009] When the cam is in a state of being moved, the springs are pressed against the top of the springs and the cams are released, and the movement of the springs causes the cams to move, thereby preventing the cams from bending and sliding.

[0010] By setting two limit assemblies, the two limit assemblies can release the limit on the rotating rod, and then the personnel can rotate the sealing plate. The rotation of the sealing plate will drive the rotating rod to rotate, and the rotation of the rotating rod will drive the torsion spring to twist until one side of the sealing plate is attached to one side of the protective shell. At this time, the limit assembly can limit the rotating rod, and under the sealing action of the two sealing plates, the two sealing plates can completely seal one side of the protective shell to ensure that dust will not fall on the fisheye lens body when the fisheye lens body is not in use, thereby ensuring the clarity of the fisheye lens body.

[0011] In the above technical solution, further, the limit assembly includes:

[0012] A sliding groove, the sliding groove is opened in the protective shell and is located on one side of the rotating rod, two limit holes are opened on the peripheral side of the rotating rod, a limit block is slidably installed in the sliding groove, one end of the limit block passes through one side of the sliding groove and extends into one of the limit holes, and the other end of the limit block is fixedly installed with a spring 2 fixed to the inner wall of the sliding groove.

[0013] In the present technical scheme, when the overall device is not in use, personnel can move the two limit blocks separately. The movement of the limit blocks will squeeze spring 2 to shrink until one end of the limit block moves out of the other limit hole. At this time, the limit block can release the limit on the rotating rod. Then the personnel can rotate the sealing plate. The rotation of the sealing plate will drive the rotating rod to rotate. The rotation of the rotating rod will drive the torsion spring to twist until one side of the sealing plate is attached to one side of the protective shell. At this time, under the action of the rebound force of spring 2, spring 2 will squeeze the limit block to move until one end of the limit block is inserted into one of the limit holes. At this time, the limit block can limit the rotating rod, and under the sealing action of the two sealing plates, the two sealing plates can completely seal one side of the protective shell to ensure that dust will not fall on the fisheye lens body when the fisheye lens body is not in use, thereby ensuring the clarity of the fisheye lens body.

[0014] In the above technical solution, further, one end of the limit block is plug-fitted into the limit hole.

[0015] In this technical solution, it is ensured that one end of the limiting block can be inserted into the limiting hole.

[0016] In the above technical solution, further, the two ends of the spring 1 are tightly welded to the sliding plate and the inner wall of the mounting groove respectively, and the two ends of the torsion spring are tightly welded to the rotating rod and the protective shell respectively.

[0017] In this technical solution, the structural stability of the spring 1 is ensured, and the structural stability of the torsion spring is ensured.

[0018] In the above technical solution, further, the cross section of the clamping block is a T-shaped structure, and the cross section of the sliding plate is an L-shaped structure.

[0019] In this technical solution, it is ensured that the card block can be stuck in the installation groove and will not fall off, and it is ensured that the sliding plate can limit the card block.

[0020] In the above technical solution, further, the plurality of springs are linearly distributed with equal spacing.

[0021] In this technical solution, it is ensured that the forces on the plurality of springs are uniform.

[0022] In the above technical solution, further, the card block and the protective shell are an integrally formed structure.

[0023] In this technical solution, the structural stability of the card block and the protective shell is ensured.

[0024] The beneficial effects of the utility model are:

[0025] 1. The fisheye lens on the drone can be inserted into the mounting slot by a person through the provided mounting slot. At this time, one end of the block will abut against the sliding plate. Then the block is moved, and the block will drive the sliding plate to move in the mounting slot. At the same time, the movement of the sliding plate will squeeze the plurality of springs to shrink. Under the limiting action of the plurality of limit rods, it can be ensured that the plurality of springs will not bend when shrinking. Until one side of the sliding plate abuts against one end of the plurality of limit rods, the block is rotated until the top of the block is attached to the top of the mounting slot. Then the moving block is released. Under the action of the rebound force of the plurality of springs, the plurality of springs will squeeze the sliding plate to move. The movement of the sliding plate will drive the block to move until the protrusion on the block is stuck in the mounting slot. At this time, the block can be fixed, so that the protective shell and the fisheye lens body can be installed on the drone body, ensuring that the fisheye lens body can be quickly installed. At the same time, no other tools are required when installing the fisheye lens body, and the operation is simple and convenient.

[0026] 2. The fisheye lens on the drone has two limit assemblies, which can release the limit on the rotating rod. Then the operator can rotate the sealing plate. The rotation of the sealing plate will drive the rotating rod to rotate, and the rotation of the rotating rod will drive the torsion spring to twist until one side of the sealing plate is attached to one side of the protective shell. At this time, the limit assembly can limit the rotating rod. Under the sealing effect of the two sealing plates, the two sealing plates can completely seal one side of the protective shell to ensure that dust will not fall on the fisheye lens body when the fisheye lens body is not in use, thereby ensuring the clarity of the fisheye lens body.
