And a switching unit:

as shown in fig. 5 to 7, the switching unit includes a coil spring 106 provided between the connection shaft 105 and the side bracket 103, and a fixed disk 108 fixedly connected to the connection shaft 105.

The lock frame 110 is slidably mounted on the side bracket 103 along the sliding direction of the anti-collision frame 200, the lock frame 110 is located on one side of the fixed disc 108 away from the outer end of the anti-collision frame 200, the anti-collision frame 200 is in contact with the lock frame 110, and when the anti-collision frame 200 moves to retract into the camera shooting shell 100, the lock frame 110 moves synchronously, a first spring 112 for driving the lock frame 110 to reset is arranged between the lock frame 110 and the side bracket 103, and the lock frame 110 moves towards the fixed disc 108.

The outer circle surface of the fixed disc 108 is provided with a locking notch 109, the lock frame 110 is provided with a locking block 111, the free end of the locking block 111 is inserted into the locking notch 109, in an initial state, the coil spring 106 is in a compressed state and is limited to release elasticity through the cooperation of the locking block 111 and the locking notch 109, when the anti-collision frame 200 is collided and retreated, the lock frame 110 is carried to synchronously move, and when the locking block 111 is separated from the locking notch 109, the coil spring 106 immediately releases elasticity to drive the connecting shaft 105 to rotate, and the camera is protected at the first time.

The anti-collision protection process of the camera is specifically shown as follows:

when the camera device is impacted, the impact is carried out on the anti-collision frame 200 at a first time, so that the anti-collision frame 200 is retracted into the camera housing 100 to move backwards, the anti-collision frame 200 is retracted to carry the lock frame 110 to move synchronously, the lock block 111 is further separated from the lock opening 109, the spring force released by the coil spring 106 drives the connecting shaft 105 to rotate, the connecting shaft 105 carries the movable shell 104 to rotate together, the protective lens 107 is timely rotated to be covered by the fixed shell 102, and at the moment, the fixed shell 102 and the movable shell 104 are matched to form a metal spherical shell shape capable of protecting the camera in 360 degrees without dead angle.

In the above process, after the protective lens 107 is completely located in the fixed shell 102, the camera is protected by the metal spherical shell without dead angle, the time taken for the coil spring 106 to release the elastic force to make the protective lens 107 completely located in the fixed shell 102 is T, the maximum distance for the collision avoidance frame 200 to continue to retreat after the locking piece 111 is separated from the locking hole 109 is S, and when the collision avoidance frame 200 retreats to the maximum distance, the collision will act on the camera housing 100, and S/T is the critical point of the collision avoidance speed in the present invention, that is, the maximum value.

Further, the above-mentioned collision protection speed refers to the collision speed when the locking piece 111 is separated from the locking hole 109, and not refers to the speed when the collision and the crash frame 200 are in contact initially, so that during the process that the collision and the crash frame 200 contact the locking piece 111 and separate from the locking hole 109, the collision is counteracted and buffered as much as possible, so that the magnitude of the collision protection speed can be reduced, and the protection performance of the present invention is further improved, based on the following:

the impact buffering counteracts the resistance force mainly from the first spring 112 and the friction force between the locking notch 109 and the locking notch 111, and as shown in fig. 7, the radial direction of the fixed disc 108 at the locking notch 109 is parallel to the sliding direction of the anti-collision frame 200, which is in the meaning that the elastic force of the coil spring 106 makes the fixed disc 108 have a rotation trend, and the rotation trend can make the locking notch 109 generate a pressure on the locking notch 111, and the direction of the pressure is distributed along the tangential direction of the fixed disc 108 at the locking notch 109, so that the radial direction of the fixed disc 108 at the locking notch 109 is parallel to the sliding direction of the anti-collision frame 200, and the direction of the pressure can be perpendicular to the contact surface of the locking notch 111 and the locking notch 109, so that the friction force between the locking notch 111 and the locking notch 109 is maximized.

In summary, in the invention, when the camera is impacted, the cooperation of the coil spring 106 and the first spring 112 plays a role in buffering to offset part of impact force, then the impact can lead the locking piece 111 to be separated from the locking opening 109, the coil spring 106 can release elasticity, and the camera can be protected without dead angle in time, and the two stages complement each other.

Further, after the collision is completed and the collision object leaves, the first spring 112 starts to release the elastic force, so that the locking piece 111 contacts with the outer wall of the fixed disc 108, at this time, as shown in fig. 1 and 3, a reset hole is formed in the outer surface of the camera housing 100, an adjusting nut 113 is rotatably installed in the reset hole, the adjusting nut 113 is coaxially connected with the fixed disc 108, the adjusting nut 113 can be screwed by a tool such as a screwdriver, so that the fixed disc 108, the connecting shaft 105 and the movable shell 104 are reset and rotated, when the locking hole 109 is restored to the initial position, the locking piece 111 is reinserted into the locking hole 109, the whole protection mechanism is reset, and the camera faces to one side of the outer end of the anti-collision frame 200 again, so that the camera is normally carried out.
