In this embodiment, energy consumption may be saved.
In some embodiments, for example, the magnetic attraction assembly 22 may be installed at the lock shaft 26, and the detection assembly 30 may include a Hall sensor. The Hall sensor may be installed at the housing 24 and located at a position opposite to the magnetic attraction assembly 22 when the lock shaft 26 is in the lock position 26a. Under normal conditions, when the lock shaft 26 moves to the lock position 26a, the magnetic attraction assembly 22 may move to a position opposite to the Hall sensor, and the Hall sensor may detect changes in the magnetic field. When the Hall sensor does not detect changes in the magnetic field, the lock shaft 26 may not be in the lock position 26a.
In some embodiments, for example, the detection assembly 30 may include a transmitter and a receiver. The transmitter and the receiver may be arranged on opposite sides of the lock hole 25. The transmitter may be used to send out detection signals, and the receiver may be used to receive detection signals sent by the transmitter. Under normal conditions, when the lock shaft 26 moves to the lock position 26a, the lock shaft 26 may pass through the lock hole 25. Therefore, the signal sent by the transmitter may be blocked by the lock shaft 26, and the receiver cannot receive the signal. When the receiver receives the signal, it may be indicated that the lock shaft 26 is not in the lock position 26a.
In some other embodiments, for example, the detection assembly 30 may include a micro switch which is at least partially located within the lock hole 25. The micro switch may be triggered when the lock shaft 26 extends into the lock hole 25. Under normal conditions, when the lock shaft 26 moves to the lock position 26a, the lock shaft 26 may be inserted into the lock hole 25 and trigger the micro switch. When the microswitch is not triggered, it may be indicated that the lock shaft 26 is not in the lock position 26a.
In some embodiments, the camera 100 may further include an input device 60. The input device 60 may be configured to respond to a user trigger and generate a locking instruction or an unlocking instruction. The controller 50 may be electrically connected to the input device 60 and the coil assembly 21. The controller 50 may be configured to control the coil assembly 21 to be energized to drive the lock shaft 26 to move to the lock position 26a when the locking instruction is received. The controller 50 may be also used to energize the coil assembly 21 to drive the lock shaft 26 to the unlock position 26b when receiving the unlocking instruction. Optionally, the input device 60 may include at least one of a button, a knob, a dial, a touch pad, a touch screen, or a voice input device 60.
In some embodiments, the camera may include two lock mechanisms 20. Of course, the number of lock mechanisms 20 included in the camera is not limited to two, and in various embodiments, the camera may include three, four, or more lock mechanisms 20. The number of lock mechanisms 20 may be configured according to actual needs.
In some embodiments, the camera 100 may further include a long exposure mode start button 70 for responding to a user's trigger and starting the long exposure mode. The controller 50 may be electrically connected to the long exposure mode start button 70 and the lock mechanism 20. The controller 50 may be used to control the lock mechanism 20 to lock the movable member 12 when the camera 100 starts the long exposure mode. In this embodiment, by controlling the lock mechanism 20 to lock the movable member 12 in the long exposure mode, the image sensor 13 may be prevented from shaking when the camera 100 is in the long exposure mode resulting in low image quality.
In some embodiments, the camera 100 may further include a shutdown button 80 which is used to respond to a user's trigger and shut down the camera 100. The controller 50 may be electrically connected to the shutdown button 80 and the lock mechanism 20. The controller 50 may be used to control the lock mechanism 20 to lock the movable member 12 when shutting down the camera 100. In this embodiment, when the camera 100 is in the shutdown mode, the movable member 12 may be in the locked state, avoiding the situation that the movable member 12 is still movable and causes a malfunction when the camera 100 is in the shutdown mode.
