As shown in fig. 7 and 8, the pen taking detection assembly 100 includes a support structure 10, a fixed bracket 30, a moving module, an elastic member 70, a photoelectric sensor 50, and a circuit board 60.

As shown in fig. 1, the bezel 300 surrounds the outer periphery of the display module 200, in other words, the bezel 300 defines a mounting area in which the display module 200 is mounted. A portion of the bezel 300 is used as the support structure 10, and a placement area for placing the handwriting pen 400 is formed on the support structure 10.

As shown in fig. 2 and 3, the fixing bracket 30 is connected to the support structure 10 and is fixed relative to the support structure 10. As shown in fig. 5 to 11, the moving module includes a moving bracket 20 and a magnetic member 40. In this embodiment, the movable support 20 is movably mounted to the fixed support 30. In other embodiments, the mobile carriage 20 may also be movably mounted to the support structure 10. The magnetic member 40 is mounted to the moving bracket 20. The movable support 20 comprises a trigger structure 23, and the movable support 20 is movable relative to the fixed support 30 and the support structure 10, and when the movable support 20 moves, the relative position between the trigger structure 23 and the emitting element changes. The elastic member 70 is disposed between the movable bracket 20 and the fixed bracket 30. In this embodiment, the elastic member 70 is a spring. In other embodiments, the elastic member 70 may be a spring, a marble, or the like.

As shown in fig. 2 and 5, when the stylus 400 is placed in the placement area of the support structure 10, the movable support 20 is driven by the magnetic member 40 to move to the first position. As shown in fig. 3 and 6, when the stylus 400 is taken out and lifted, the movable support 20 moves to the second position by the elastic member 70.

The photoelectric sensor 50 includes an emitting element 51 and a receiving element 52, and the emitting element 51 is used for emitting sensing light. The transmitting element 51 and the receiving element 52 are electrically connected to the circuit board 60, respectively.

In this embodiment, as shown in fig. 11 and fig. 4 to fig. 6, the transmitting element 51 and the receiving element 52 are disposed on the same side of the triggering structure 23, and when the triggering structure 23 is located on the optical path of the sensing light, the triggering structure 23 reflects the sensing light to the receiving element 52. In other embodiments, the triggering structure 23 blocks the sensing light from transmitting to the receiving element 52.

In this embodiment, the movement of the movable support 20 from the first position to the second position is that the optical signal received by the receiving element 52 changes, and the change of the optical signal is converted into the change of the electrical signal, so as to sense whether the movable support 20 moves to the second position and thus sense whether the stylus 400 is removed from the supporting structure 10. Wherein, the trigger structure 23 is located on the light path of the sensing light, which means that the sensing light irradiates on the trigger structure 23.

In this embodiment, the pen placing and taking actions of the handwriting pen 400 are converted into the moving actions of the moving support 20, the moving support 20 moves to adjust the relative position between the trigger structure 23 and the emitting element 51, so that the trigger structure 23 is moved away from or onto the light path of the sensing light, and then is converted into the change of the optical signal in the photoelectric sensor 50, and then the change of the optical signal is converted into the change of the electrical signal under the action of the detection circuit, and the pen taking actions of the handwriting pen 400 are detected through the detection of the position of the moving support 20.

Compared with the detection of the pen taking action by a mechanical touch switch, the pen taking action is detected by the cooperation of the photoelectric sensor 50 and the trigger structure 23, the trigger structure 23 has a certain volume, and even if a certain error exists in the assembly, the adjustment of the relative position between the trigger structure 23 and the sensing light rays can still be realized in the moving process of the moving bracket 20, so that the change of an optical signal is ensured, and the precision and the reliability of pen taking detection are ensured. And the triggering structure 23 and the photoelectric sensor 50 are not in actual contact during detection, so that the loss of parts is avoided, and the service life is prolonged.

When the user removes the stylus 400 from the supporting structure 10, the movable support 20 is reset to the second position under the action of the elastic member 70, the movable support 20 drives the photoelectric sensor 50 to move to the opposite side of the triggering structure 23, the triggering structure 23 is on the light path of the sensing light, the sensing light emitted by the emitting element 51 is reflected by the reflecting portion 231, the reflected sensing light is received by the receiving element 52, and the circuit board 60 generates current. Realizing pen lifting detection.

In the arrangement mode of the photoelectric sensor 50, the transmitting element 51 and the receiving element 52 are arranged in the same device, so that two elements do not need to be independently installed during installation, and the two elements do not need to be specially aligned, so that the installation difficulty is reduced, and detection errors caused by assembly errors are avoided. With this arrangement, the reliability of the triggering structure 23 reflecting the sensing light to the reflecting element is improved. The optical sensor is mounted on the fixed support 30, and when the pen is put and taken out, the position of the photoelectric sensor 50 is not changed, so that the false reflection of other structures is avoided, and the detection reliability is improved.

the emitting element 51 is disposed on the fixed support 30, the reflecting element and the triggering structure 23 are disposed on the movable support 20, and the emitting element 51 and the reflecting element are disposed on the same side of the triggering structure 23. When the movable support 20 moves between the first position and the second position, the relative position between the trigger structure 23 and the transmitting element 51 changes, and the receiving element 52 changes the receiving state of the optical signal, so as to realize pen taking signal sensing.

The photoelectric sensor 50 is arranged in a third mode:

the emitting element 51 and the reflecting element are both disposed on the moving bracket 20, and the triggering structure 23 is disposed on the fixed bracket 30. When the movable support 20 moves between the first position and the second position, the relative position between the trigger structure 23 and the transmitting element 51 changes, and the receiving element 52 changes the receiving state of the optical signal, so as to realize pen taking signal sensing.

The photoelectric sensor 50 is arranged in a fourth mode:

the emitting element 51 is provided on the moving bracket 20, the reflecting element and the triggering structure 23 are provided on the fixed bracket 30, and the emitting element 51 and the reflecting element are provided on the same side of the triggering structure 23. When the movable support 20 moves between the first position and the second position, the relative position between the trigger structure 23 and the transmitting element 51 changes, and the receiving element 52 changes the receiving state of the optical signal, so as to realize pen taking signal sensing.

The fifth mode of arrangement of the photoelectric sensor 50:

the transmitting element 51 and the receiving element 52 are both arranged between the fixing parts, and the triggering structure 23 is arranged on the movable bracket 20. When the pen is put, when the movable support 20 is located at the first position, the optical path channel between the transmitting element 51 and the receiving element 52 is not blocked, and the receiving element 52 receives the sensing signal. When the pen is taken, the movable support 20 is located at the second position, the triggering structure 23 blocks the light path channel, the receiving element 52 cannot receive the sensing signal, and the detection circuit detects the change of the receiving state of the optical signal to realize pen taking detection.

Referring to fig. 2 and 3, in the present embodiment, the frame 300 includes a front plate as the supporting structure 10. Other components of the pen taking detection assembly 100 are disposed inside the frame 300. The magnetic member 40 is a magnet, and the magnetic portion is made of a metal material that can be attracted to the magnet. When the stylus 400 is placed on the support structure 10, a magnetic attraction force is generated between the magnetic portion of the stylus 400 and the magnetic member 40, and the stylus 400 is attracted to and held by the support structure 10.

The frame 300 further includes an outer side plate and a rear side plate, the rear side plate is disposed opposite to the front side plate, and the outer side plate is disposed between the front side plate and the rear side plate. In other embodiments, the support structure 10 is an outer or rear panel of the bezel 300, and the support structure 10 may also be a back panel of an interactive flat panel. In other words, the user may place the stylus 400 on the upper, lower, left, right, or rear side of the interactive tablet when the user is not using the stylus 400. In other embodiments, a receiving slot may be provided in the support structure 10, and the stylus 400 may be inserted into the receiving slot.

In the present embodiment, the movable stand 20 is driven to move to adjust the light signal receiving state of the receiving element 52, and the stylus 400 is kept stored in the placement area of the frame 300. In this way, the stylus 400 is stored without any special fixing structure.

During the movement of the moving bracket 20 to the first position, the elastic member 70 is deformed, and the elastic member 70 accumulates elastic force. When the movable bracket 20 is in the first position, the magnetic attraction force is greater than the elastic force to hold the movable bracket 20 in the first position. When the pen 400 is picked up and lifted, the magnetic attraction force is smaller than the elastic force, and the movable support 20 moves to the second position under the action of the elastic force.

In other embodiments, the magnetic portion is a magnet and the magnetic member 40 is also a magnet, the magnetic member 40 and the magnetic portion being mutually exclusive or attractive. The magnetic part of the stylus 400 may be configured as a magnet, and the magnetic member 40 in the mobile module may be configured as a magnetically movable metal.

With continued reference to fig. 9 and 11, in order to ensure that the triggering structure 23 more stably reflects the sensing light to the receiving element 52, the light reflecting portion 231 is a light reflecting curved surface, and the light reflecting curved surface faces the transmitting element 51 and the receiving element 52. The light emitted from the emitting element 51 is radial, and has a certain arc-shaped light reflecting portion 231, so that the amount of light reflected by the light reflecting portion 231 to the receiving element 52 can be increased, and the detection accuracy can be improved, relative to the planar light reflecting portion 231.

In other embodiments, the light reflecting portion 231 may be a v-shaped light reflecting surface, a U-shaped light reflecting surface, a planar light reflecting surface, or the like.

With reference to fig. 5 to 8 and fig. 10 to 11, the movable bracket 20 includes a first frame 21, a trigger plate, and a first elastic buckle 22, where the trigger plate protrudes relative to the first frame 21 so as to extend to the other side of the fixed bracket 30 through the avoidance hole. The first frame 21 is provided with a first mounting groove, the magnetic piece 40 is inserted into the first mounting groove, and the limiting surface of the first elastic buckle 22 abuts against the magnetic piece 40 to limit the magnetic piece 40 from falling out of the first mounting groove, so that the magnetic piece 40 is mounted.

The first frame 21 is disposed between the support structure 10 and the fixing bracket 30, in other words, the magnetic member 40 is disposed between the support structure 10 and the fixing bracket 30. When the pen is placed, the moving bracket 20 moves forward, as shown in fig. 2, to be attached to the inner surface of the front side plate of the frame 300.
