Description

Technical Field

[0001] The invention relates to a small space occupancy rate follow-up expandable and retractable shielding mechanism, and particularly belongs to the technical field of shielding mechanisms. Background Art

[0002] The camera cover is an important part of the drone and is the best solution to protect the camera during flight. The key to the design of the drone camera cover lies in the mechanical drive system, reliable locking mechanism, durable materials, and precise control system to ensure the stability and functionality of the cover in different states. In recent years, the camera cover technology has made great progress;

[0003] The shielding mechanism is retracted when the camera needs to work. There are few retractable camera shielding mechanisms available, and existing achievements are mainly in the form of fixed camera shielding mechanisms, which currently have no retractability. Summary of the invention

[0004] The purpose of the present invention is to provide a small space occupancy follow-up retractable shielding mechanism to solve the problem of the retraction of the shielding mechanism of the drone camera.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: the invention includes a driving motor and a shielding cover, and also includes a camera body, a driving assembly and a transmission assembly;

[0006] A camera body is arranged on one side of the driving motor, and a driving component is connected to the output end of the driving motor. The driving component is located on the outer wall of the camera body. A shielding cover is arranged on the camera body in the opposite direction of the driving motor. A transmission component is arranged on one side of the shielding cover, and the transmission component is linked with the driving component.

[0007] The driving motor provides driving power to the mechanism, the shielding cover completely shields the camera body, and the driving assembly cooperates with the transmission assembly to ensure synchronization of the movement of the retractable shielding cover;

[0008] The drive assembly includes a guide rod, a linear bearing and a synchronizer ring;

[0009] A guide rod is fixedly installed on the outer wall of the camera body, and a linear bearing is connected to the outer side of one end of the guide rod. The linear bearing is arranged on the inner side of the synchronization ring, and the synchronization ring is arranged on the outer side of the camera body;

[0010] Furthermore, the movement of the synchronizer ring is more stable through the cooperation of the two guide rods and the linear bearing.

[0011] The driving assembly also includes a screw rod, a coupling and a nut;

[0012] The output shaft end of the driving motor is fixedly connected with a coupling, which is installed on the guide rod. The other end of the coupling is fixedly connected with a screw rod, a nut is connected to the outside of the screw rod, and a synchronizer ring is fixedly connected to the outside of the nut.

[0013] Furthermore, the driving motor drives the lead screw to rotate through the coupling, and the lead screw is connected to the nut through a thread, so that the lead screw can drive the synchronizing ring to move toward the driving motor through the nut.

[0014] The transmission assembly includes a rotating shaft and a main shaft;

[0015] A rotating shaft is fixedly installed at an equal angle on one side of the synchronous ring, a main shaft is connected to the inner side of the rotating shaft, and a shielding cover is fixedly connected to one side of the main shaft, and four shielding covers are provided;

[0016] Furthermore, the rotating shaft can drive the four shielding covers to unfold synchronously through the main shaft.

[0017] The transmission assembly also includes a torsion spring;

[0018] A torsion spring is connected to one side of the rotating shaft, and a shielding cover is connected to the other side of the torsion spring;

[0019] Furthermore, the shielding hood is opened by overcoming the torque of the torsion spring, thereby realizing the opening of the shielding hood, and the shielding hood can be retracted again through the resetting action of the torsion spring, thereby improving the shielding protection of the mechanism to the camera body.

[0020] Also includes a limit ring;

[0021] A limit ring is fixedly installed on one side of the camera body, and the limit ring is arranged in four shielding covers;

[0022] Furthermore, the size of the limit ring can be designed according to the size space of the shielding cover. The limit ring is fixed to the outside of the camera body by a fixing component. The limit ring does not move during the movement of the shielding cover. During the backward movement of the four-petal shielding cover, the limit ring can act on the shielding cover, so that the shielding cover overcomes the torque of the torsion spring and opens, thereby realizing the opening of the shielding cover.

[0023] The beneficial effects of the present invention are:

[0024] 1. The structure is set up that two screw rods rotate on the outside of the camera body, so that the screw rod can drive the synchronous ring to move toward the driving motor through the nut, so that the synchronous ring drives the four shielding covers to retract and expand. The double screw drive setting ensures the synchronization of the mechanism movement. The four-petal shielding cover is adopted, which makes the mechanism have good symmetry and splicing tightness.

[0025] 2. By installing limit rings in four shielding covers, the limit rings can always be in close contact with the shielding covers, thereby ensuring that the shielding covers, the camera body and the fairing do not interfere with each other, thereby improving the stability of the mechanism.

[0026] 3. By connecting the main shaft to the inner side of the rotating shaft, the colinear rotating shaft and the main shaft can constrain the shielding cover, thereby making the mechanism have a single degree of freedom and limiting the movement trajectory of the shielding cover.

[0035] The following will be combined with the attached Figure 1-7 , clearly and completely describe the technical solutions in the embodiments.

[0036] Specific implementation method 1: Figure 1-3 As shown, the overall mechanism includes two driving motors 1, a camera body 4 and four split-flap shielding covers 3. The two driving motors 1 are symmetrically arranged on both sides of the camera body 4. The output end of the driving motor 1 is connected to a driving component, and the driving component is located on the outer side wall of the camera body 4. A transmission component is arranged on one side of the shielding cover 3, and the transmission component is connected with the driving component. The two driving motors 1 drive the four split-flap shielding covers 3 to close and unfold through the cooperation of the driving component and the transmission component, so that the four split-flap shielding covers 3 cooperate to complete the timely protection of the camera body 4.

[0037] Two guide rods 7 are fixedly installed on the outer wall of the camera body 4 corresponding to the driving motor 1, and a coupling 5 is rotatably installed on the inner side of the guide rod 7. One end of the coupling 5 is fixedly connected to the output shaft end of the driving motor 1, and the other end of the coupling 5 is fixedly connected to the lead screw 2, so that the two driving motors 1 can be stably installed on the outer side of the camera body 4. At this time, the driving motor 1 can drive the lead screw 2 to rotate through the coupling 5. Since the outer side of the lead screw 2 is threadedly connected with a nut 6, the outer side of the nut 6 is fixedly connected with a synchronizer ring 9, and the synchronizer ring 9 is arranged on the outer side of the camera body 4, the lead screw 2 can drive the synchronizer ring 9 to move on the outer side of the camera body 4 through the nut 6. Since a linear bearing 8 is slidably connected to the outer side of one end of the guide rod 7, and the linear bearing 8 is arranged on the inner side of the synchronizer ring 9, when the synchronizer ring 9 moves, the synchronizer ring 9 can slide on the outer side of the guide rod 7 through the linear bearing 8, and the two guide rods 7 cooperate to complete the limiting of the synchronizer ring 9, so that the movement of the synchronizer ring 9 is more stable;

[0038] Specific implementation method 2: Figure 4-7 As shown, since a rotating shaft 10 is fixedly mounted on one side of the synchronizer ring 9, a main shaft 12 is fixedly mounted on one side of the four shielding covers 3, and the inner side of the rotating shaft 10 is rotatably connected to the main shaft 12, when the synchronizer ring 9 moves toward the driving motor 1, the synchronizer ring 9 will drive the four shielding covers 3 to move synchronously through the cooperation of the rotating shaft 10 and the main shaft 12;

[0039] Since a torsion spring 11 is connected to one side of the rotating shaft 10, and a shielding cover 3 is connected to the other side of the torsion spring 11, and a limiting ring 13 is fixedly installed on one side of the camera body 4, and the limiting ring 13 is arranged in the four shielding covers 3, when the four shielding covers 3 move synchronously, the limiting ring 13 will act on the four shielding covers 3, so that the four shielding covers 3 overcome the torque of the torsion spring 11 and open, thereby realizing the synchronous opening of the four shielding covers 3.

[0040] The limiting ring 13 can always be in close contact with the shielding cover 3, so as to ensure that there is no interference between the shielding cover 3, the camera body 4 and the fairing, thereby improving the stability of the mechanism. The size of the limiting ring 13 can be designed according to the size space of the shielding cover 3. The limiting ring 13 is fixed to the outside of the camera body 4 by a fixing component, and the limiting ring 13 does not move during the movement of the shielding cover 3.

[0041] The above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent replacement and improvement made to the above embodiments without departing from the content of the technical solution of the present invention, based on the technical essence of the present invention, within the spirit and principles of the present invention, still fall within the protection scope of the technical solution of the present invention.
