In the scheme that is used for realizing carrying a detection function at present, current carry a detection structure and can be through setting up in the frame or frame rear side and dabber, dabber stretches out the frame surface through the inspection hole that the frame front side was seted up, or set up the plastic button at the frame front side and dabber between the button to and frame front side and dabber set up the plastic button that has the magnet between and trigger the mode such as trigger. In the above manner, when the stylus 50 is in the pen-placing state, the pen body of the stylus 50 directly abuts against the plastic key, or the plastic key is driven by the stylus 50, and the plastic key is driven by magnetic force to move back and forth to press and flick the light touch switch, so that the display device turns on or off the corresponding auxiliary function. However, because the light touch key belongs to a more precise device, and each part has production and assembly tolerance again, therefore, under the state that the light touch key is triggered, the pressing depth of the light touch key can have the possibility of being too big or too small, thereby causing the damage of the light touch key to lose efficacy or detect badly, for this reason, the utility model provides a following implementation mode.

As shown in fig. 2 to 7, the pen lifting detection structure includes a supporting member 10 and a circuit board 20 fixed relative to the supporting member 10, the circuit board 20 is used as a detection module of the pen lifting detection structure, a control circuit is formed on a surface of the circuit board, in an application of an interactive flat plate, the circuit board 20 can be electrically connected to a central control unit in the interactive flat plate, and when the circuit board 20 obtains a pen lifting signal or a pen placing signal, the circuit board 20 can send a corresponding detection signal to the central detection unit, so that the central detection unit controls other function modules in the interactive flat plate to be opened or closed. If in the using state of the stylus 50, the user takes the stylus 50 off the support 10, the circuit board 20 obtains a corresponding pen lifting signal, and sends the pen lifting signal to the central control unit, the central control unit controls the interactive tablet to open the annotation and writing functions, in the non-using state of the stylus 50, the user places the stylus 50 back to the support 10, the circuit board 20 obtains a corresponding pen placing signal, and sends the pen placing signal to the central control unit, and the central control unit controls the interactive tablet to close the corresponding function.

The supporting member 10 is formed with a receiving portion 11 for receiving the stylus pen 50, a front side surface of the receiving portion 11 provides a receiving position of the stylus pen 50, the receiving portion 11 may be a plane structure or a cambered surface structure according to a specific installation manner of the pen lifting detection structure, and a detection hole is selectively opened on the receiving portion 11 according to the pen lifting detection structure.

The circuit board 20 is specifically disposed at the rear side of the receiving portion 11 and is kept relatively fixed with the support 10, and the circuit board 20 can be correspondingly disposed at the rear side of the support 10 or inside the support 10 according to different structures of the support 10, and the circuit board 20 is correspondingly disposed in the accommodating cavity 12 inside the support 10 due to the adoption of the support 10 with the profile frame structure in the present embodiment.

As shown in fig. 7, a contact switch is disposed on the circuit board 20, the contact switch includes a switch contact 21 and a switch elastic sheet 22, the switch contact 21 and the switch elastic sheet 22 are electrically connected to the circuit board 20, the switch elastic sheet 22 can elastically deform under an external force and abut against the switch contact 21, so that the contact switch is closed, and the switch elastic sheet 22 can elastically reset to a state of being separated from the switch contact 21 when the external force is removed from the switch elastic sheet 22. The control logic of the circuit board 20 can be adaptively adjusted according to the control mode of the pen lifting detection structure, and the present embodiment provides several optional embodiments for the detection mode of the pen lifting detection structure:

1. under the condition that the switch elastic sheet 22 abuts against the switch contact 21, the control circuit on the circuit board 20 is closed and acquires a pen lifting signal, and under the condition that the switch elastic sheet 22 is separated from the switch contact 21, the control circuit on the circuit board 20 is disconnected and acquires a pen placing signal;

2. when the switch spring 22 abuts against the switch contact 21, the control circuit on the circuit board 20 is closed to obtain the pen-out signal, and when the switch spring 22 is separated from the switch contact 21, the control circuit on the circuit board 20 is opened to obtain the pen-up signal.

In order to drive the switch elastic sheet 22 in the pen lifting and placing states, a movable trigger support 30 is disposed between the supporting member 10 and the circuit board 20, specifically, a side of the circuit board 20 on which the contact switch is disposed is defined as a front side of the circuit board 20, in this embodiment, a rear side of the receiving portion 11 is disposed opposite to a front side of the circuit board 20, the trigger support 30 is movably disposed between a rear side of the receiving portion 11 and the front side of the circuit board 20, the trigger support 30 can act on the switch elastic sheet 22 to generate elastic deformation during a movement of the trigger support 30 toward a side close to the circuit board 20, and the trigger support 30 can release the switch elastic sheet 22 during a movement of the trigger support 30 toward a side close to the receiving portion 11, so that the switch elastic sheet 22 loses elastic reset due to external force.

When the stylus pen 50 is placed in the storage portion 11, the stylus pen 50 can drive the trigger support 30 to release or act on the switch elastic sheet 22, so as to open or close the contact switch, and the specific stylus pen 50 is used for driving the trigger support 30 to release or act on the switch elastic sheet 22, specifically depending on whether the control circuit of the circuit board 20 is set to open to obtain the pen placing signal or close to obtain the pen placing signal.

Through the above-mentioned implementation mode that adopts the contact switch as the control switch of circuit board 20, compared with the existing mode that adopts the light touch key/micro-switch, the contact switch adopts switch shell fragment 22 to contradict switch contact 21 or break away from switch contact 21 in the elastic deformation process to control the on-off of the control circuit of circuit board 20, the switch stroke of switch shell fragment 22 is bigger than general switch and the above-mentioned light touch key, it can adapt to the depth of pressing within a certain stroke range, and switch shell fragment 22 has certain elastic deformation range and has higher toughness, therefore, it still has certain push-down allowance under the contact state, even if there is certain processing, assembly tolerance in the spare part of the pen lifting detection structure, switch shell fragment 22 can also keep not destroyed under the great depth of pressing, switch shell fragment 22 can also guarantee the stability of the closed state of the contact switch within a certain range of depth of pressing, thereby the condition that the switch has been avoided the push-down depth too big and has caused the failure and damage, thus improve the reliability of pen lifting detection, and the whole structure is relatively simple, compared with the light touch key and low cost scheme.

As shown in fig. 2 to 6, as an embodiment for driving the trigger bracket 30, the embodiment uses the magnetic force of a magnet to drive the trigger bracket 30 to move between the receiving portion 11 and the circuit board 20, so that the surface of the receiving portion 11 in the embodiment does not need to be provided with corresponding detection holes, the aesthetic appearance of the interactive tablet can be further improved, the processing steps of the supporting member 10 are also reduced, and the assembly difficulty of the pen-lifting detection structure is reduced.

The pen lifting detection structure further includes a first magnetic member 31 and a second magnetic member 51, the first magnetic member 31 is fixedly disposed with the trigger bracket 30, and the second magnetic member 51 is correspondingly disposed on the stylus pen 50, it can be understood that the second magnetic member 51 may be disposed on the surface or inside of the stylus pen 50 according to actual requirements, or the second magnetic member 51 is directly used as a pen body of the stylus pen 50, which is not specifically limited in this embodiment.

The trigger bracket 30 of the present embodiment is based on the following principle:

when the stylus pen 50 is placed on the front side of the storage portion 11, the second magnetic member 51 is in a state of being close to the first magnetic member 31, so that a magnetic force action can be generated between the first magnetic member 31 and the second magnetic member 51, and the first magnetic member 31 drives the trigger bracket 30 fixed to the first magnetic member 31 to release or act on the switch elastic sheet 22 through the magnetic force action generated between the first magnetic member 31 and the second magnetic member 51.

It should be noted that, when the pen lifting detection mode is set to acquire the pen releasing signal when the control circuit of the circuit board 20 is disconnected, and when the control circuit of the circuit board 20 is closed, the trigger bracket 30 in the pen lifting state is kept at the position acting on the switch elastic sheet 22, the present embodiment adopts the setting mode that the first magnetic member 31 and the second magnetic member 51 are opposite in opposite polarity, so that when the handwriting pen 50 is placed at the storage position, a magnetic attraction force can be generated between the first magnetic member 31 and the second magnetic member 51, the handwriting pen 50 can be magnetically attracted and fixed on the storage portion 11, and the trigger bracket 30 can be driven by the first magnetic member to move toward the handwriting pen 50, i.e. toward the storage portion 11, so that the trigger bracket 30 can release the switch elastic sheet 22, such an embodiment can not only realize the control of the trigger bracket 30 through a magnet, but also realize the stable storage function of the handwriting pen 50, save the number of parts related to the pen lifting detection structure, also make the structure simpler, and reduce the processing and assembly costs;

when the pen lifting detection mode is set to obtain a pen releasing signal when the control circuit of the circuit board 20 is closed, and obtain a pen lifting signal when the control circuit of the circuit board 20 is disconnected, the trigger bracket 30 in the pen lifting state is kept at the position of releasing the switch elastic sheet 22, in this embodiment, the first magnetic member 31 and the second magnetic member 51 are arranged in a homopolar opposition manner, so that when the stylus pen 50 is placed at the storage position, a mutually repulsive magnetic force can be generated between the first magnetic member 31 and the second magnetic member 51, here, because the two magnetic members generate a repulsive magnetic force, the stylus pen 50 cannot be stably placed on the storage portion 11, a fixing structure for fixing the stylus pen 50 needs to be arranged on the storage portion 11, or the stylus pen 50 is fixed by other methods, after the stylus pen 50 is fixed on the storage portion 11, the first magnetic member is repelled by the second magnetic member, so that the trigger bracket 30 is driven by the first member to move away from the stylus pen 50, i.e., to approach the circuit board 20, thereby allowing the trigger bracket 30 to act on the switch elastic sheet 22, and completing the detection of the pen releasing state.

As another embodiment for driving the trigger bracket 30, the trigger bracket 30 may also be directly driven by a pen body of the stylus pen 50, a detection hole (not shown) is formed in the storage portion 11, the trigger bracket 30 maintains a state of at least partially extending out of the detection hole in a pen lifting state, and when the stylus pen 50 is placed in the storage portion 11, the pen body of the stylus pen 50 abuts against the trigger bracket 30 extending out of the detection hole portion, so that the trigger bracket 30 moves in a direction approaching the circuit board 20 as a whole and acts on the switch elastic sheet 22, thereby completing the detection of the pen placing state.

As shown in fig. 4 to 6, it can be understood that, since the switch elastic sheet 22 itself has a certain elastic resetting capability, the switch elastic sheet 22 can be configured to be elastically reset to a state of being separated from the switch contact 21 without an external force acting on the trigger bracket 30.

Further, in a pen-lifting state, that is, in a state where the trigger holder 30 is not driven by the stylus pen 50, in order to keep the trigger holder 30 in a corresponding position state, the pen-lifting detection structure further includes an elastic reset member 32, the elastic reset member 32 is disposed between the support member 10 and the trigger holder 30, and when the stylus pen 50 is placed in the storage portion 11, an elastic force of the elastic reset member 32 acting on the support member 10 and the trigger holder 30 is smaller than a magnetic force between the first magnetic member 31 and the second magnetic member 51.

When the magnetic force between the first magnetic member 31 and the second magnetic member 51 is a magnetic attraction force, the elastic reset member 32 continuously applies an elastic force to the trigger bracket 30, the elastic force moving towards the direction of pressing the switch elastic sheet 22;

when the magnetic force between the first magnetic member 31 and the second magnetic member 51 is a magnetic repulsive force, the elastic restoring member 32 continuously applies an elastic force to the trigger bracket 30, which moves toward the direction of releasing the switch elastic sheet 22.

It can be understood that the elastic force applied by the elastic reset piece 32 to the trigger support 30 is opposite to the force of the stylus pen 50 driving the trigger support 30 to move, so that when the trigger support 30 loses the driving force of the stylus pen 50 after the stylus pen 50 is lifted, the trigger support 30 can be reset by the elastic reset piece 32 to the state of acting on the switch elastic sheet 22 or releasing the switch elastic sheet 22. Adopt elasticity piece 32 that resets's mode can let trigger support 30 reset to original position better under carrying a state on, let its release switch shell fragment 22, compare only the elasticity of switch shell fragment 22 itself resets the power and supports the scheme that pushes away trigger support 30, protection switch shell fragment 22 that can be better, reduce switch shell fragment 22's elasticity fatigue speed, and, reset piece 32 drive trigger support 30 through elasticity, also can let carry carrying a detection structure carry a detection more reliable, also let this structure can adopt more different implementation modes, improve and carry the commonality that a detection structure.

As shown in fig. 2-5 and 8-9, in order to provide a mounting space for mounting the trigger bracket 30 and the circuit board 20, a mounting bracket 40 is disposed between the trigger bracket 30 and the support 10, the mounting bracket 40 is fixedly connected to the support 10, specifically, the mounting bracket 40 is fixed to the rear side of the receiving portion 11, the circuit board 20 is fixedly disposed on the mounting bracket 40, and the trigger bracket 30 is also movably connected to the mounting bracket 40, so that the trigger bracket 30 can reciprocate between the receiving portion 11 and the mounting bracket 40.

A guide structure is disposed between the mounting bracket 40 and the trigger bracket 30, and the guide structure is used for limiting the movement direction of the trigger bracket 30.

Specifically, the guiding structure includes a first guiding portion 41 disposed on the mounting bracket 40 and a second guiding portion 33 disposed on the trigger bracket 30, wherein the first guiding portion 41 and the second guiding portion 33 are guided and matched along a direction perpendicular to the rear side of the receiving portion 11 and the front side of the circuit board 20.

A guide structure commonly used in the mechanical field can be adopted between the first guide portion 41 and the second guide portion 33, and the guide structure can be formed by combining different components such as a guide pillar, a guide sleeve, a sliding block, a sliding groove and the like. In this embodiment, the first guide portion 41 is provided as a guide hole opened at the front side of the mounting bracket 40, the second guide portion 33 is provided as a guide post protruded at the rear side of the trigger bracket 30, and the guide post is movably inserted into the guide hole. In order to make the whole pen lifting detection structure more compact and save the installation space of the pen lifting detection structure, the elastic reset piece 32 is a spring, and the elastic reset piece 32 is sleeved on the guide column so that two ends of the elastic reset piece 32 can respectively act on the trigger bracket 30 and the installation bracket 40.

It can be understood that there are various assembling manners of the elastic restoring element 32, as shown in fig. 4-5 and fig. 8-9, the elastic restoring element 32 of this embodiment is disposed in a guiding hole, the guiding hole is disposed at the front side of the mounting bracket 40 and is provided with a supporting platform 46 for limiting the axial movement of the elastic restoring element 32 along the guiding column, and one end of the guiding column far from the trigger bracket 30 is provided with a limiting cap 36, so that the two opposite ends of the elastic restoring element 32 respectively support against the supporting platform 46 and the limiting cap 36, and act on the mounting bracket 40 and the trigger bracket 30.

Of course, the elastic restoring member 32 may be disposed outside the guiding hole, and the outer diameter thereof is set to be larger than the diameter of the guiding hole, so as to abut between the mounting bracket 40 and the triggering bracket 30 in a directly exposed manner.

And in order to improve the stability of trigger support 30 in the motion process, and improve the sensitivity that stylus 50 drive triggered support 30, trigger support 30 and the direction of the extension of receiving portion 11 and be parallel to each other, first magnetism spare 31 sets up inside trigger support 30, and extend the setting along the length direction who triggers support 30, through the aforesaid setting mode, can let the receiving area be bar structure, with the form that matches stylus 50, improve the stability of stylus 50 when being inhaled in receiving portion 11 by magnetism, and, even there is certain skew in the position of placing of stylus 50 and receiving area, also can let great first magnetism inhale the piece and inhale the second magnetism on receiving portion 11.

It is understood that the first guiding portion 41 can be a guiding column, and the corresponding second guiding portion 33 can be a guiding hole.

In order to prevent the trigger bracket 30 from being instantaneously moved toward or away from the circuit board 20 by the elastic restoring member 32 after the magnetic force is lost during the pen lifting process, a buffer member 42 is disposed between the mounting bracket 40 and the trigger bracket 30, and/or a buffer member 42 is disposed between the circuit board 20 and the trigger bracket 30.

The buffer member 42 is used for buffering an acting force of the trigger bracket 30 acting on the switch elastic sheet 22, so as to effectively protect the trigger bracket 30, the circuit board 20 and the mounting bracket 40, and prevent the trigger bracket 30 from being instantaneously moved by an elastic acting force of the elastic resetting member 32 to cause impact and vibration on the mounting bracket 40 or the circuit board 20.

In this embodiment, in order to restrict the movement of the trigger bracket 30, a limiting structure is disposed between the mounting bracket 40 and the trigger bracket 30, wherein the limiting structure includes a first limiting portion 43 disposed at the front side of the mounting bracket 40 and a second limiting portion 34 disposed at the rear side of the trigger bracket 30, the first limiting portion 43 can limit the movement limit position of the second limiting portion 34, and when the trigger bracket 30 moves toward the direction close to the circuit board 20, the first limiting portion 43 can abut against the second limiting portion 34 to limit the trigger bracket 30 to move continuously toward the direction.

Specifically, a first limiting portion 43 is formed on a side surface of the mounting bracket 40 close to the accommodating portion 11, a mounting portion 44 is formed on a side of the mounting bracket 40 away from the accommodating portion 11, the circuit board 20 is fixedly arranged on the mounting portion 44, a through hole 45 communicating the first limiting portion 43 with the mounting portion 44 is formed in the mounting bracket 40, the contact switch is correspondingly located at the through hole 45, a trigger rod 35 is arranged on a side of the trigger bracket 30 located at the second limiting portion 34, and the trigger rod 35 can extend into the through hole 45, so that the trigger rod 35 can be close to the release switch elastic sheet 22 to press or be away from the release switch elastic sheet 22 along with the movement of the trigger bracket 30.

In this embodiment, the first guide portion 41 is a guide hole penetrating through the mounting bracket 40 on the side of the first limit portion 43 and the mounting portion 44, and is used as a guide post of the second guide portion 33 to be penetrated through the guide hole, and the limit cap 36 is disposed behind the end portion of the guide post, so that the mounting bracket 40 is located between the trigger bracket 30 and the limit cap 36, and the limit cap 36 is located between the mounting bracket 40 and the circuit board 20, so that the buffer 42 can be disposed between the circuit board 20 and the limit cap 36 to buffer the limit cap 36, the outer diameter of the limit cap 36 is larger than the diameter of the guide hole, and besides being capable of limiting the elastic reset piece 32, during the movement of the trigger bracket 30 in the direction close to the receiving portion 11, the limit cap 36 can also be abutted against the mounting portion 44 side of the mounting bracket 40 to limit the trigger bracket 30 from continuing to move in the direction, and finally realizing the limit of the trigger bracket 30 in two directions.
