The sensing detection assembly 10 is used for reliably closing the camera 21 in a physical shielding manner when the user needs to close the camera 21 but the camera 21 is not closed, so as to prevent the above security problem of privacy disclosure.

Referring to fig. 1 and fig. 2, in particular, the sensing module 10 of the present embodiment includes: a shielding piece 11, a magnetic piece 12 and an inductive switch 13.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the sensing detection assembly 10 of the scheme is applied to various terminal devices with the camera module 20, is used for shielding or opening the camera 21 according to different use states of the terminal devices, improves the safety level and reliability of the terminal devices, and can feed back shielded or opened state information to the terminal devices so that users can master the state information, and the state information feedback implementation mode is simple and reliable. Specifically, when the device is installed, the shielding piece 11 can be movably installed on one side of the camera 21, and when the shielding piece 11 moves in two opposite directions, the camera 21 can be shielded or opened; then, the magnetic member 12 is mounted on the shutter 11, and the inductive switch 13 is mounted on one side of the shutter 11.

Therefore, when the shielding piece 11 moves away from the inductive switch 13 to shield the camera 21, the inductive switch 13 can be in triggering fit with the magnetic piece 12 to generate a shielding signal, or when the shielding piece 11 moves close to the inductive switch 13 to open the camera 21, the inductive switch 13 can be in triggering fit with the magnetic piece 12 to generate an opening signal, the detection means triggered by the magnetic piece 12 and the inductive switch 13 is not affected by factors such as light intensity, structural shape and the like, the measurement precision and reliability are high, the number of parts is small, the structure composition is simple, the occupied installation space is small, and the universality is more universal.

In this embodiment, the terminal device further includes a signal transmission unit and a display unit. Briefly, when the shielding piece 11 is far away from the sensing switch 13 to shield the camera 21, a shielding signal generated by triggering of the magnetic piece 12 of the sensing switch 13 can be transmitted to the operation and analysis module through the signal transmission unit, the shielding signal processed by the operation and analysis module can be finally displayed on the display unit, the display unit can be a touch screen of a mobile phone, at the moment, a user knows that the camera 21 is shielded by the shielding piece 11, and even if the camera 21 fails to perform unexpected shooting and recording, the problem of accidental shooting and user privacy leakage can not occur.

When the shielding piece 11 is close to the inductive switch 13 to turn on the camera 21, the turn-on signal generated by the inductive switch 13 triggered by the magnetic piece 12 can be transmitted to the operation analysis module through the signal transmission unit and finally displayed on the display unit, and at the moment, the user knows that the camera 21 is turned on by the shielding piece 11, so that the user can not perform privacy activities, conversations and the like under the condition of obtaining the prompt information, and the privacy safety can still be ensured.

On the basis of any of the above embodiments, the inductive switch 13 is configured as a reed switch, and the reed switch is used for being electrically connected to the circuit board 22. The reed switch is a switch device which can be triggered to open when encountering magnetic force, and the magnetic part 12 in the embodiment is specifically provided as a magnet.

With reference to fig. 3 and 4, when the shielding element 11 shields the camera 21, the magnet is far away from the reed pipe, the reed pipe is in an off state without being acted by magnetic force, the reed pipe feeds back a shielding signal to the CPU of the terminal device, and the IO level of the CPU is low.

With reference to fig. 1 and fig. 2, preferably, the reed switch is disposed at a board edge of the circuit board 22 close to the magnetic element 12. At this time, the reed pipe is closest to the shielding piece 11, which is beneficial to reducing the moving stroke of the shielding piece 11, so that the magnetic piece 12 on the shielding piece 11 can move a small distance to form a triggering relation with the reed pipe, the action sensitivity of the induction detection assembly 10 is improved, and the waiting time of a user is reduced.

Of course, it should be noted that in other embodiments, the reed switch may be disposed at other positions on the circuit board 22, as long as it can be in triggering relation with the magnetic member 12, and the scope of the present application is also covered.

Alternatively, the reed switch can be mounted and fixed on the circuit board 22 by screwing, bonding, riveting, welding, etc., according to actual needs.

It should be further noted that the use of the signal-triggered feedback mechanism with the magnetic element 12 cooperating with the reed switch is not a limitation on the scope of the present application, and in other embodiments, other signal-triggered feedback mechanisms known in the art may be used.

Generally, the sensing detection assembly 10 is installed inside the housing of the terminal device together with the camera module 20, that is, the shield 11 moves to shield or open the camera 21, which cannot be manually operated due to the obstruction of the housing. In this regard, in some embodiments, the inductive sensing assembly 10 further includes a movable base 14 and a driver for outputting a telescopic driving force, the driver being in direct or indirect driving connection with the movable base 14.

The driver is electrically connected with the control module and can output telescopic driving force under the control of the command of the control module, so that the driving moving seat 14 can move linearly in a reciprocating manner, the purpose that the shielding piece 11 is controlled to shield or open the camera 21, and the magnetic piece 12 and the reed pipe are controlled to be matched in a triggering manner is achieved. The structure is simple, the operation is reliable, and the response speed is high.

Specifically, the driver may be an air cylinder, an electric push rod, an oil cylinder, or the like, which is capable of directly outputting the telescopic power. Taking the actuator as an air cylinder as an example, the moving seat 14 is connected to a piston rod of the air cylinder and can be driven by the piston rod to reciprocate. Of course, the driver may also be a motor, a rotary cylinder, or other devices that output rotary power, but at this time, a reversing transmission assembly that can convert the rotary power into linear telescopic power needs to be provided to be connected to the driver, and the reversing transmission assembly is connected to the movable seat 14 at the same time, so that the movable seat 14 can drive the shielding member 11 and the magnetic member 12 to reciprocate, and the shielding or opening of the camera 21 and the triggering of the reed pipe can be respectively completed.

With reference to fig. 1 and fig. 2, in further embodiments, the sensing module 10 further includes a rail 15, the movable base 14 is movably disposed on the rail 15, and the shielding member 11 is disposed on the movable base 14. Thus, the track 15 can play a role in guiding and limiting the movement of the movable seat 14, the rigidity of the movable seat 14 is increased, the power arm of the driver is prevented from completely bearing the gravity of the movable seat 14, the load burden of the driver is reduced, and the service life is prolonged.

It is understood that the movable seat 14 may be directly slidably disposed on the rail 15, or may be rotatably disposed on the rail 15 via a roller.

In addition, in some other embodiments, the induction detecting assembly 10 further includes a first limiting member and a second limiting member, the first limiting member and the second limiting member are respectively installed at two opposite ends of the rail 15, and both the first limiting member and the second limiting member can abut against the moving base 14. The first limiting member and the second limiting member can respectively limit the moving base 14 moving to the limit positions at the two ends of the rail 15, so as to avoid the problem of jamming caused by derailment of the moving base 14.

Preferably, the first limiting part and the second limiting part are both preferably made of soft materials such as plastics, so that noise generated when the first limiting part and the second limiting part are in collision contact with the movable base 14 can be avoided, and the use experience and the service life of the terminal device can be prevented from being influenced.

With reference to fig. 1 and fig. 2, in addition to any of the above embodiments, the sensing module 10 further includes a fixed carrier 16, the fixed carrier 16 is disposed on the moving base 14, the fixed carrier 16 is provided with a mounting hole, and the magnetic element 12 is embedded in the mounting hole. The magnetic part 12 is embedded in the mounting hole, and the magnetic part 12 can be stably mounted under the clamping and restraining of the hole wall, so that the magnetic part 12 cannot fall off from the shielding part 11 due to external vibration or impact. That is, compared with the method of directly mounting the magnetic member 12 to the shielding member 11 by bonding, screwing, etc., the present embodiment can not only ensure the magnetic member 12 to be mounted stably and simply, but also does not cause physical damage to the shielding member 11 and the magnetic member 12.

Further, on the basis of any of the above embodiments, the shielding member 11 is provided with a shielding portion and an observation window which are adjacently arranged, and the shielding portion and the observation window are arranged side by side along the moving direction of the shielding member 11. The shielding part can shield the camera 21, and when the shielding piece 11 moves to enable the observation window to be opposite to the camera 21, the camera 21 can work normally. Moreover, in the above embodiment, as for the manner that the shielding element 11 moves in a large stroke to completely shield or completely avoid the camera 21, since the shielding portion and the observation window are arranged side by side along the moving direction, the shielding element 11 can move a small distance at this time, and the position switching between the shielding portion and the observation window can be completed, which is more beneficial to completing the work state switching of the sensing detection assembly 10.
