Description

Technical Field

[0001] This utility model demonstrates a Kent window for use with drones and a drone, belonging to the field of drone technology. Background Technology

[0002] With the advancement of drone technology, drone aerial photography is being used more and more widely. During drone aerial photography, moisture or dust and other debris in the air can easily adhere to the camera lens, which may affect the camera's shooting effect and reduce the quality of aerial photography. Cleaning the lens each time is also time-consuming and laborious. Utility Model Content

[0003] The purpose of this invention is to solve the problem of debris easily adhering to camera lenses. To this end, a Kent window for drones and a drone are provided. The Kent window uses airflow to rotate and thus fling away debris from the surface of the protective lens.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] Kent windows for drones include:

[0006] The rotating base is rotatably connected to the camera of the drone, and has several radially outward-extending blades on its outer periphery;

[0007] Protective goggles, fixed to the rotating base, form a shield for the camera lens;

[0008] The blades drive the rotating base to rotate relative to the camera under the action of airflow, and the protective mirror rotates synchronously with the rotating base to shake off debris from the surface of the protective mirror.

[0009] The beneficial effects of using this utility model are:

[0010] The protective lens described in this invention is fixed on the rotating base and forms a shield for the camera. The shield can block moisture, dust, and other debris in the air, thereby protecting the camera lens and keeping it clean. In addition, during the flight of the drone, the airflow acts on the blades, which in turn causes the rotating base to rotate relative to the camera. The protective lens rotates with the rotating base, allowing it to move at high speed. This centrifugal force then throws away debris from the surface of the protective lens, keeping the front of the camera lens clean and ensuring a better field of view, which helps improve the shooting effect. Furthermore, the blades are located on the outer periphery of the rotating base and do not obstruct the camera lens themselves, ensuring that there are no other foreign objects obstructing the field of view on the front of the camera, thus providing a better field of view for the camera.

[0011] Preferably, the rotating base includes a fixed base and a rotating component. The fixed base is fitted onto the head of the camera, and the rotating component is rotatably connected to the fixed base via a bearing. The blades and the protective lens are both fixed to the rotating component. Using the aforementioned technical solution, the rotating base and the fixed base are rotatably connected via a bearing. Both the fixed base and the bearing prevent direct contact between the rotating base and the camera, preventing damage to the camera's housing due to the rotation of the rotating base and reducing the possibility of camera damage. Furthermore, the bearing ensures smoother and more seamless rotation of the rotating base, allowing the protective cover to rotate at high speeds.

[0012] Preferably, the rotating component is arranged in a ring shape, with the blades evenly distributed on the outer periphery of the rotating component, and the protective mirror is fixed to the inner periphery of the rotating component.

[0013] Preferably, the inner wall of the rotating component is provided with radially inwardly extending ribs, and the protective lens is fixed to the side of the ribs facing away from the camera. Using the aforementioned technical solution, the ribs can reliably support the protective lens, ensuring a reliable safe distance between the protective lens and the camera lens, preventing direct contact between the protective lens and the camera lens, and avoiding scratches to the camera lens due to the rotation of the protective lens; in addition, the ribs can also reduce the possibility of the protective lens loosening and improve the positioning stability of the protective lens and the rotating component.

[0014] Preferably, the bearing includes an outer ring and an inner ring that can rotate relative to each other. The outer ring is interference-fitted with the rotating component, and an abutment ring is provided on the side of the rib facing away from the protective mirror, abutting against the outer ring of the bearing. Using the aforementioned technical solution, the abutment ring can limit direct contact between the rib and the bearing, thereby preventing relative friction caused by contact between the rib and the inner ring of the bearing, and reducing the possibility of damage to the rib and the bearing.

[0015] Preferably, the inner diameter of the abutment ring is larger than the inner diameter of the bearing outer ring, and the inner diameter of the rib is smaller than the outer diameter of the bearing inner ring. Using the aforementioned technical solution, the rib can shield the bearing outer ring and balls, thus improving aesthetics.

[0016] Preferably, the inner wall of the rotating component has a guide surface on the side closest to the camera. Using the aforementioned technical solution, the guide surface can guide the bearing into the rotating component, effectively reducing the assembly difficulty of the bearing and the rotating component and improving assembly efficiency.

[0017] Preferably, the outer periphery of the fixing seat is provided with a mounting platform extending radially outward, and the end of the fixing seat is provided with a limiting rib, with the bearing constrained between the mounting platform and the limiting rib.

[0018] Preferably, the rotating base is rotatably connected to the head of the camera via a bearing.

[0019] This utility model also demonstrates a drone, including a body and a camera movably mounted on the body, the head of the camera being rotatably connected to a Kent window, the Kent window being a Kent window for drones as described in any of the above.

[0032] Example 1:

[0033] like Figures 1 to 5 As shown in the figure, this embodiment demonstrates a Kent window for a drone, including a rotating base 1 and a protective lens 14. The rotating base 1 is fitted onto the front end of the drone's camera 2 and is rotatably connected to the camera 2. The rotating base 1 has a through hole in the middle, and the drone's camera 2 is located inside the through hole. The protective lens 14 is fixed to the front end of the rotating base 1 and seals the through hole. After the rotating base 1 and the protective lens 14 are assembled, they form a shield for the lens 21 of the camera 2. The outer periphery of the rotating base 1 has several radially outward-extending blades 121. Under the action of airflow, the blades 121 drive the rotating base 1 to rotate relative to the camera 2. The protective lens 14 rotates synchronously with the rotating base 1 to dislodge debris from the surface of the protective lens 14.

[0034] In this embodiment, the protective mirror 14 is fixed on the rotating base 1 and forms a shield for the camera 2. The shield can block moisture, dust and other debris in the air, thereby protecting the lens 21 of the camera 2 and keeping it clean. In addition, during the flight of the drone, the airflow acts on the blades 121, which in turn causes the rotating base 1 to rotate relative to the camera. The protective mirror 14 rotates with the rotating base 1, allowing the protective mirror 14 to generate high-speed motion. This centrifugal force is used to throw away debris from the surface of the protective mirror 14, keeping the front of the lens 21 of the camera 2 clean and ensuring that the camera 2 has a better field of view, which helps to improve the shooting effect of the camera 2. Secondly, the blades 121 are set on the outer periphery of the rotating base 1. The blades 121 themselves do not obstruct the lens 21 of the camera 2, so there are no other foreign objects obstructing the field of view on the front of the camera 2, providing a better field of view for the camera 2 to shoot.

[0035] Specifically, such as Figure 2 As shown, in this embodiment, the rotating base 1 includes a fixed base 11 and a rotating component 12. The fixed base 11 is fitted onto the housing of the camera 2 and is fixedly connected to the camera 2. The rotating component 12 is rotatably connected to the fixed base 11 via a bearing 13. Blades 121 are disposed on the outer periphery of the rotating component 12, and a protective lens 14 is fixed to the inner side of the rotating component 12. Airflow acts on the blades 121 and drives the rotating base to rotate through the blades 121. The protective lens 14 rotates synchronously with the rotating base, thereby generating high-speed rotation. Water droplets, dust, and other debris on the surface of the protective lens 14 are affected by centrifugal force. Under the action of the rotating seat 1, the surface of the protective lens 14 is automatically cleaned, making the surface of the protective lens 14 cleaner so as to provide a clearer field of view for the camera 2. In addition, the rotating seat 1 and the fixed seat 11 are rotatably connected by the bearing 13. Both the fixed seat 11 and the bearing 13 can prevent the rotating seat 1 from making direct contact with the camera 2, preventing the housing of the camera 2 from being damaged by the rotation of the rotating seat 1, and reducing the possibility of damage to the camera 2. Secondly, the bearing 13 can make the rotation of the rotating seat 1 smoother and more smoothly, ensuring that the protective cover can rotate at high speed.

[0036] It is understandable that in other embodiments, the rotating seat 1 may also be directly rotatably connected to the head of the camera 2 via the bearing 13.

[0037] Specifically, in this embodiment, the rotating component 12 is arranged in a ring shape, the through hole forms a mounting hole on the inner side of the rotating component 12, the blades 121 are evenly distributed on the outer periphery of the rotating component 12, and the protective mirror 14 is fixed in the mounting hole of the rotating component 12.

[0038] Specifically, such as Figure 3 and Figure 4As shown, in this embodiment, the inner wall of the rotating component 12 is provided with a radially inwardly extending rib 122. The protective mirror 14 is fixed to the side of the rib 122 facing away from the camera 2. The peripheral wall and edge of the protective mirror 14 are bonded to the rib 122 and the inner wall of the rotating component 12 by adhesive, thereby realizing the fixed connection between the protective mirror 14 and the rotating component 12. The rib 122 can provide reliable support for the protective mirror 14, ensuring that a reliable safe distance can be maintained between the protective mirror 14 and the camera lens 21, preventing direct contact between the protective mirror 14 and the camera lens 21, and avoiding scratches to the camera lens 21 due to the rotation of the protective mirror 14. In addition, the rib 122 can also reduce the possibility of the protective mirror 14 becoming loose and improve the positioning stability of the protective mirror 14 and the rotating component 12.

[0039] Specifically, such as Figure 4 As shown, in this embodiment, the bearing 13 includes an outer ring and an inner ring that can rotate relative to each other. A plurality of balls are provided between the outer ring and the inner ring. The inner ring is fitted onto the outer periphery of the fixed seat 11, and the inner wall of the inner ring is interference-fitted with the fixed seat 11. The outer wall of the outer ring is interference-fitted with the inner wall of the rotating component 12. The side of the rib 122 facing away from the protective mirror 14 is provided with an abutment ring 123. The abutment ring 123 abuts against the outer ring of the bearing 13. The abutment ring 123 can restrict the rib 122 from making direct contact with the bearing 13, thereby avoiding the rib 122 from contacting the inner ring of the bearing 13 and generating relative friction, reducing the possibility of damage to the rib 122 and the bearing 13. In addition, in this embodiment, the inner diameter of the abutment ring 123 is larger than the inner diameter of the outer ring of the bearing 13, and the inner diameter of the rib 122 is smaller than the outer diameter of the inner ring of the bearing 13. The rib 122 can shield the outer ring and balls of the bearing 13, which helps to improve the aesthetics.

[0040] To make the assembly of the rotating component 12 and the rotating shaft easier and less strenuous, in this embodiment, a guide surface is provided on the inner wall of the rotating component 12 near the camera 2. The guide surface can guide the bearing 13 to be installed into the rotating component 12, which can effectively reduce the assembly difficulty of the bearing 13 and the rotating component 12 and improve the assembly efficiency.

[0041] like Figure 5As shown, in this embodiment, the fixing base 11 is also ring-shaped. The fixing base 11 is fitted onto the outer periphery of the head of the camera 2 and is fixedly connected to the outer shell of the camera 2. The fixing base 11 has an extension 111 extending axially. The extension 111 is located at the end of the fixing base 11 facing away from the protective lens 14. During the installation of the fixing base 11 and the camera 2, the extension 111 can play a guiding role, which helps to reduce the installation difficulty of the fixing base 11 and the camera 2. In addition, the extension 111 can also increase the contact area between the fixing base 11 and the camera 2, thereby strengthening the connection stability between the fixing base 11 and the camera 2. In addition, in this embodiment, the outer periphery of the fixing base 11 is provided with a mounting platform 112 extending radially outward, and the end of the fixing base 11 is provided with a limiting rib 113. The bearing 13 is restricted between the mounting platform 112 and the limiting rib 113, which helps to improve the assembly stability of the bearing 13 and the fixing base 11, reduce the possibility of the bearing 13 shaking, and make the assembly of the rotating part 12 and the fixing base 11 more stable and reliable.
