为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明部分实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。In order to make the objects, technical solutions and advantages of the present invention more comprehensible, some embodiments of the present invention are described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

在触控领域，用户可以使用主动笔在电子设备的触摸屏幕上进行书写。用于书写的主动笔通常包括笔芯和笔管，笔芯是执行书写动作的主体，也是主动笔的核心部件。In the touch field, users can use the active pen to write on the touch screen of an electronic device. The active pen for writing usually includes a refill and a pen tube, and the refill is the main body for performing the writing action, and is also the core component of the active pen.

图2示出了根据本申请的实施例的用于主动笔的笔芯的一种示例性结构。 FIG. 2 illustrates an exemplary structure of a refill for an active pen in accordance with an embodiment of the present application.

如图2所示，根据本申请实施例的用于主动笔的笔芯2包括：笔尖组件10；压力检测装置20，与笔尖组件10连接，用于感测和确定来自笔尖组件10的压力信息；以及支撑架30，用于容置笔尖组件10和压力检测装置20，其中，支撑架30内部具有螺纹孔301，该支撑架30通过螺纹孔与压力检测装置20螺纹连接。根据本申请实施例的笔芯能够根据检测到的压力的变化使得通过笔尖组件10书写的内容能够呈现在与主动笔对应的电子设备的显示器上。As shown in FIG. 2, the refill 2 for an active pen according to an embodiment of the present application includes: a nib assembly 10; a pressure detecting device 20 coupled to the nib assembly 10 for sensing and determining pressure information from the nib assembly 10. And a support frame 30 for accommodating the nib assembly 10 and the pressure detecting device 20, wherein the support frame 30 has a threaded hole 301 therein, and the support frame 30 is screwed to the pressure detecting device 20 through a threaded hole. The refill according to an embodiment of the present application enables the content written by the nib assembly 10 to be presented on the display of the electronic device corresponding to the active pen according to the detected change in pressure.

主动笔笔芯的笔尖组件10在电子设备的显示器(例如触摸屏幕)上书写的时候，将受到的压力传递到压力检测装置20。压力检测装置20感测笔尖受到的压力，对感测到的压力进行分析，并将经过分析处理后的数据转换为电信号，以将电信号通过传导部件(例如传导弹簧)发送至笔尖组件10。当笔尖组件10接触电子设备的触摸屏幕时，与触摸屏幕端的电容进行耦合，在触摸屏幕上呈现出与所述压力对应的书写的内容。例如，笔尖受到的压力越大，所书写的字体越粗。The pen tip assembly 10 of the active pen refill transmits the received pressure to the pressure detecting device 20 while writing on a display (e.g., a touch screen) of the electronic device. The pressure detecting device 20 senses the pressure received by the pen tip, analyzes the sensed pressure, and converts the analyzed data into an electrical signal to transmit the electrical signal to the nib assembly 10 through a conductive member (eg, a conductive spring). . When the nib assembly 10 contacts the touch screen of the electronic device, it is coupled with the capacitance of the touch screen end, and the written content corresponding to the pressure is presented on the touch screen. For example, the greater the pressure on the nib, the thicker the font being written.

根据本申请的实施例，笔尖组件10受到的压力可以通过例如弹簧的传导部件传输到压力检测装置20。根据本申请的实施例，压力检测装置20例如可以包括压力传感器201和处理电路202。在用户使用主动笔在电子设备的显示器上书写时，笔尖组件10受到的压力将传输到压力传感器201，从而改变压力传感器201的输出电压。压力传感器201的输出电压被输出到处理电路202，由处理电路202对压力传感器201的输出电压进行分析，例如，处理电路202可以将接收到的输出电压与其所存储的压力传感器的输出电压(例如，表示压力传感器在前一刻感测的压力的输出电压)进行比较，以确定笔尖组件10所受到的压力的变化，并生成表示该压力的变化的电信号，以将电信号通过传导部件发送至笔尖组件10。According to an embodiment of the present application, the pressure received by the nib assembly 10 can be transmitted to the pressure detecting device 20 through a conductive member such as a spring. According to an embodiment of the present application, the pressure detecting device 20 may include, for example, a pressure sensor 201 and a processing circuit 202. When the user writes on the display of the electronic device using the active pen, the pressure received by the nib assembly 10 is transmitted to the pressure sensor 201, thereby changing the output voltage of the pressure sensor 201. The output voltage of the pressure sensor 201 is output to the processing circuit 202, which analyzes the output voltage of the pressure sensor 201. For example, the processing circuit 202 can output the received output voltage to the output voltage of the pressure sensor it stores (eg, , the output voltage of the pressure sensed by the pressure sensor at the previous moment is compared to determine the change in pressure experienced by the nib assembly 10, and an electrical signal representative of the change in the pressure is generated to pass the electrical signal through the conducting portion The pieces are sent to the nib assembly 10.

根据本申请的实施例，压力传感器201可以采用本领域公知的用于主动笔的任何压力传感器，只要其能够检测来自笔尖的压力即可。压力传感器201对于来自笔尖的压力的检测操作是本领域公知的，在此不再赘述。此外，处理电路202对于压力传感器201检测到的表示压力的输出电压的处理(包括对于输出电压的比较)也是本领域公知的，在此不再赘述。According to an embodiment of the present application, the pressure sensor 201 may employ any pressure sensor known in the art for an active pen as long as it can detect the pressure from the pen tip. The detection operation of the pressure sensor 201 for the pressure from the nib is well known in the art and will not be described herein. In addition, the processing of the output voltage indicative of the pressure detected by the pressure sensor 201 (including the comparison of the output voltage) by the processing circuit 202 is also well known in the art and will not be described herein.

例如，可以通过在压力检测装置20的主板上打孔，并且将螺钉通过该孔旋拧至支撑架30的螺纹孔301中，来将压力检测装置20和支撑架30装配在一起。如图2所示，支撑架30可以在前端和后端分别装配有一个螺纹孔301，并且通过在装配有压力检测装置20的主板的两端分别打一个孔，将两个螺钉分别旋拧至位于支撑架30前端和后端的螺纹孔301，来将压力检测装置20和支撑架30螺纹连接在一起。For example, the pressure detecting device 20 and the support frame 30 can be assembled by punching a hole in the main plate of the pressure detecting device 20 and screwing the screw through the hole into the threaded hole 301 of the support frame 30. As shown in FIG. 2, the support frame 30 may be respectively fitted with a threaded hole 301 at the front end and the rear end, and the two screws are respectively screwed to each other by respectively making a hole at both ends of the main board equipped with the pressure detecting device 20.

虽然图2示出的是支撑架前端和后端分别具有一个螺纹孔的结构，但是本申请不限于此。本领域技术人员可以理解，例如也可以仅在支撑架的前端或者后端配置一个螺纹孔，或者也可以在支撑架的不同位置配置多个螺纹孔。Although FIG. 2 shows a structure in which the front end and the rear end of the support frame respectively have one threaded hole, the present application is not limited thereto. It will be understood by those skilled in the art that, for example, a threaded hole may be disposed only at the front end or the rear end of the support frame, or a plurality of threaded holes may be disposed at different positions of the support frame.

此外，除了上述使用螺钉将支撑架和压力检测装置螺纹连接在一起之外，本领域技术人员可以理解也可以采用其他的螺纹连接方式。例如，也可以使用螺栓或者让螺柱等其他螺纹元件将支撑架和压力检测装置连接在一起。 Further, in addition to the above-described screwing of the support frame and the pressure detecting device together using screws, those skilled in the art will appreciate that other threaded connections may be employed. For example, the support frame and the pressure detecting device can also be connected together using bolts or other threaded elements such as studs.

本申请中支撑架30与压力检测装置20通过螺纹方式装配在一起，使得支撑架30与压力检测装置能够紧固地装配在一起，从而确保压力检测装置20在主动笔使用时或者掉落时不会产生相对滑动，具有良好的稳定性。In the present application, the support frame 30 and the pressure detecting device 20 are screwed together so that the support frame 30 and the pressure detecting device can be tightly fitted together, thereby ensuring that the pressure detecting device 20 is not used when the active pen is used or dropped.

The contact eliminates the gap existing between the tail of the pen tip 101 and the pressure detecting device 20, so that the pen tip assembly 10 does not move inside the pen tube at the time of writing, thereby improving the writing experience.

The front end of the support frame having the threaded structure 302 is thereby assembled by threaded engagement to receive the nib assembly 10.

与现有技术中笔尖导向套40与支撑架30通过卡扣方式连接相比，根据本申请实施例的笔尖导向套40与支撑架30通过螺纹结构连接，可以有效保证笔尖101和笔尖夹持件102移动的稳定度，防止笔尖产生明显晃动。Compared with the prior art, the nib guide sleeve 40 and the support frame 30 are connected by a snap connection, and the nib guide sleeve 40 and the support frame 30 according to the embodiment of the present invention are connected by a thread structure, thereby effectively securing the nib 101 and the nib holder. The stability of the movement of 102 prevents the pen tip from swaying significantly.

根据本申请的另一实施例，支撑架30的前端可以套接有第二弹性部件303，该第二弹性部件303的一端与压力检测装置30电连接，另一端可以与笔嘴电连接，从而能够通过第二弹性部件303使压力检测装置20与包括笔嘴的笔管电连通。According to another embodiment of the present application, the front end of the support frame 30 may be sleeved with a second elastic member 303, one end of which is electrically connected to the pressure detecting device 30, and the other end may be connected to the pen. The mouth is electrically connected so that the pressure detecting device 20 can be electrically connected to the pen tube including the pen tip by the second elastic member 303.

根据本申请，笔管包括笔管本体和笔嘴，笔嘴作为笔管的一部分用于与笔管本体一起固定笔芯。例如，在将笔芯放置于笔管本体后，通过将笔嘴装配于(例如旋拧至)笔管本体，从而将笔芯安装并固定于笔管中。According to the present application, the pen tube includes a pen tube body and a pen mouth, and the pen mouth is used as a part of the pen tube for fixing the refill together with the pen tube body. For example, after the pen core is placed on the pen tube body, the pen core is mounted and fixed in the pen tube by fitting (for example, screwing) the pen tip to the pen tube body.

第二弹性部件303例如可以是弹簧，其可以被套接于支撑架30前端的台阶上；第二弹性部件303的一端可以焊接至压力检测装置20上，另一端被拧入笔管的笔嘴压紧，从而可以确保压力检测装置与笔管的电连通。The second elastic member 303 may be, for example, a spring that can be sleeved on the step at the front end of the support frame 30; one end of the second elastic member 303 can be welded to the pressure detecting device 20, and the other end is screwed into the pen tube of the pen tube. Tight, thereby ensuring electrical communication between the pressure sensing device and the barrel.

根据本申请，在主动笔的笔芯中除了使用本领域公知的用于主动笔的压力检测装置之外。本申请还提供一种如图5所示的用于主动笔的笔芯的压力检测装置。According to the present application, in addition to the pressure detecting device for the active pen known in the art, the refill of the active pen. The present application also provides a pressure detecting device for a refill of an active pen as shown in FIG.

如图5所示，压力检测装置20可以包括：弹性组件211，其一端连接至主动笔的笔尖组件10；随所述弹性组件211的形变而移动的磁性器件212，该磁性器件212被设置于所述弹性组件211中；磁感器件213，与磁性器件212间隔放置，用于感应磁性器件212周围的磁场并将磁场转换为电信号以基于电信号确定主动笔的笔芯受到的压力；以及磁感支撑件214，与弹性组件211连接，且用于支撑磁感器件213，其中，磁感支撑件213在靠近所述磁性器件的一侧具有台阶结构T，在笔尖组件受到的压力大于预定值的情况下，台阶结构T阻扰所述弹性组件形变。As shown in FIG. 5, the pressure detecting device 20 may include: a resilient member 211 having one end connected to the pen tip assembly 10 of the active pen; and a magnetic device 212 moving along with the deformation of the elastic member 211, the magnetic device 212 being disposed on The elastic component 211 is disposed at a distance from the magnetic device 212 for sensing a magnetic field around the magnetic device 212 and converting the magnetic field into an electrical signal to determine a pressure applied to the refill of the active pen based on the electrical signal; a magnetic sensing support 214 coupled to the elastic component 211 and configured to support the magnetic sensing device 213, wherein the magnetic sensing support 213 is adjacent to the magnetic device The step structure T is provided on one side, and the step structure T hinders the deformation of the elastic member in the case where the pressure applied to the nib assembly is greater than a predetermined value.

根据本申请的实施例，弹性组件211的一端连接至主动笔的笔尖组件，并且在笔尖组件受到压力的情况下发生形变。例如，弹性组件211可以包括弹簧，更具体地，例如，弹性组件211可以包括弹片性支撑环和与该弹性支撑环连接的弹性部件(例如弹簧，但不限于此)。According to an embodiment of the present application, one end of the elastic member 211 is coupled to the nib assembly of the active pen and deforms when the nib assembly is subjected to pressure. For example, the elastic component 211 may include a spring, and more specifically, for example, the elastic component 211 may include a resilient support ring and an elastic member (such as a spring, but is not limited thereto) connected to the elastic support ring.

磁性器件212可以是例如磁铁、磁体等能够形成磁场的任何磁性器件。例如，磁性器件212可以例如固定在弹性组件211中间的孔内，例如可以将磁性器件212焊接到弹性组件211的、与笔尖组件10连接的一端，从而在弹性组件211由于受到来自笔尖组件的压力而发生形变时，磁性器件212随着弹性组件211的形变而移动、从而改变位置，并且随着磁性器件212的位置变化，其所形成的磁场也将发生变化。 Magnetic device 212 can be any magnetic device capable of forming a magnetic field, such as a magnet, magnet, or the like. For example, the magnetic device 212 can be secured, for example, in a hole in the middle of the resilient member 211, for example, the magnetic device 212 can be soldered to one end of the resilient member 211 that is coupled to the tip assembly 10 such that the resilient member 211 is subjected to pressure from the tip assembly When deformation occurs, the magnetic device 212 moves with the deformation of the elastic member 211, thereby changing the position, and as the position of the magnetic device 212 changes, the magnetic field formed by it also changes.

根据本申请的实施例，磁感器件213与磁性器件212间隔开放置，用于感测磁性器件212形成的磁场以及磁场变化。当磁性器件由于弹性组件211发生变形而移动时，磁感器件213可以感测到磁性器件212形成的磁场发生变化。In accordance with an embodiment of the present application, magnetic sensing device 213 is spaced apart from magnetic device 212 for sensing magnetic fields formed by magnetic device 212 as well as changes in magnetic fields. When the magnetic device moves due to deformation of the elastic member 211, the magnetic sensing device 213 can sense a change in the magnetic field formed by the magnetic device 212.

根据本申请的实施例的磁感器件213可以是能够测量磁场强度和/或磁场方向的任何磁感器件，例如霍尔(Hall)元件，各向异性磁电阻(Anisotropic Magnetoresistance，AMR)元件、电感器等。磁感器件213可以感测由于弹性组件211的形变(例如，包括但不限于弹性组件的轴向伸缩、偏转)导致的磁场变化。The magnetic sensing device 213 according to an embodiment of the present application may be any magnetic sensing device capable of measuring the magnetic field strength and/or the magnetic field direction, such as a Hall element, an anisotropic magnetoresistance (AMR) element, an inductor. And so on. The magnetic sensing device 213 can sense changes in the magnetic field due to deformation of the resilient component 211 (eg, including but not limited to axial expansion, deflection, and deflection of the resilient component).

根据本申请，弹性组件211发生的形变可以包括沿弹性组件211轴向方向的压缩和伸展。例如，当笔尖组件受到的压力变大时，弹性组件211会发生压缩形变，使得固定在弹性组件211中间的孔内的磁性器件212向磁感器件213靠近，从而磁感器件213感受到的磁性器件212形成的磁场的磁场强度将增大。反之，当笔尖组件受到的压力减小时，弹性组件211的变形减小，使得固定在弹性组件211中间的孔内的磁性器件212远离磁感器件213，从而磁感器件213感受到的磁性器件形成的磁场的磁场强度将减小。According to the present application, the deformation of the elastic component 211 may include compression and extension in the axial direction of the elastic component 211. For example, when the pressure applied to the nib assembly becomes large, the elastic member 211 may occur. The compression deformation causes the magnetic device 212 fixed in the hole in the middle of the elastic member 211 to approach the magnetic sensing device 213, so that the magnetic field strength of the magnetic field formed by the magnetic device 212 sensed by the magnetic sensing device 213 will increase. On the contrary, when the pressure applied to the nib assembly is reduced, the deformation of the elastic member 211 is reduced, so that the magnetic device 212 fixed in the hole in the middle of the elastic member 211 is away from the magnetic sensing device 213, so that the magnetic device sensed by the magnetic sensing device 213 is formed. The magnetic field strength of the magnetic field will decrease.

弹性组件211发生的形变还可以包括沿弹性组件211轴向方向发生的偏转。例如，弹性组件211可在笔尖组件的压力推动下，沿着图5所示的A点发生偏转，使磁感器件213接受到的磁通量(即感应到的磁场)发生变化。The deformation that occurs with the resilient member 211 can also include deflection that occurs along the axial direction of the resilient member 211. For example, the elastic member 211 can be deflected along the point A shown in FIG. 5 under the pressure of the nib assembly to change the magnetic flux (ie, the sensed magnetic field) received by the magnetic sensing device 213.

根据本申请的实施例，磁感支撑件214可以套接在弹性组件211内，即将弹性组件211套接在磁感支撑件214上。磁感支撑件214可以由例如塑料、橡胶等绝缘材料制成。例如，可以通过将磁感器件213放置在磁感支撑件214的表面上设置的凹槽内，来容置并固定磁感器件213。According to the embodiment of the present application, the magnetic sensing support 214 can be sleeved in the elastic component 211, that is, the elastic component 211 is sleeved on the magnetic sensing support 214. The magnetic induction support 214 may be made of an insulating material such as plastic, rubber or the like. For example, the magnetic sensing device 213 can be housed and fixed by placing the magnetic sensing device 213 in a recess provided on the surface of the magnetic sensing support 214.

虽然以上示出了通过将磁感器件213放置在磁感支撑件214的凹槽内来固定磁感器件213，但是本申请不限于此。例如，也可以通过在弹性组件211和磁感器件213之间放置固定板材来与磁感支撑件214一起容置并固定磁感器件213。Although the above shows that the magnetic sensing device 213 is fixed by placing the magnetic sensing device 213 in the groove of the magnetic sensing support 214, the present application is not limited thereto. For example, it is also possible to accommodate and fix the magnetic sensing device 213 together with the magnetic sensing support 214 by placing a fixing plate between the elastic member 211 and the magnetic sensing device 213.

根据本申请磁感支撑件214可以在靠近磁性器件的一侧具有台阶结构T，在笔尖组件受到的压力大于预定值的情况下，弹性组件211通过例如抵靠所述台阶结构T而停止形变。According to the present application, the magnetic induction support 214 may have a stepped structure T on the side close to the magnetic device, and in the case where the pressure applied by the nib assembly is greater than a predetermined value, the elastic assembly 211 stops deformation by, for example, abutting against the stepped structure T.

例如，如图5所示，当主动笔的笔尖组件垂直下落时，弹性组件211在受到笔尖组件的冲击力的情况下，沿A点发生形变，当弹性组件211上的B点接触到磁感支撑件214的台阶C点时，停止形变。从而，能够防止弹性组件211 过度形变而发生损坏，增强了主动笔的抗跌落能力。For example, as shown in FIG. 5, when the nib assembly of the active pen falls vertically, the elastic member 211 is deformed along point A while being subjected to the impact force of the nib assembly, and the point B on the elastic member 211 is in contact with the magnetic sense. When the step C of the support member 214 is stopped, the deformation is stopped. Thereby, the elastic member 211 can be prevented Excessive deformation and damage, enhance the anti-drop ability of the active pen.

根据本申请的一个实施例，压力检测装置20还可以包括：处理电路(未示出)，与磁感器件213电连接，处理电路被配置为从磁感器件213接收表示磁场变化的电信号，并且基于电信号确定笔尖组件受到的压力。According to an embodiment of the present application, the pressure detecting device 20 may further include: a processing circuit (not shown) electrically connected to the magnetic sensing device 213, the processing circuit being configured to receive an electrical signal representing the magnetic field change from the magnetic sensing device 213, And determining the pressure experienced by the nib assembly based on the electrical signal.

根据本申请的一个实施例，磁感器件103可以包括与所述处理电路电连接的霍尔器件。According to an embodiment of the present application, the magnetic sensing device 103 may include a Hall device electrically connected to the processing circuit.

在磁感器件103被配置为用于感应磁性器件102周围的磁场的磁场强度的霍尔器件的情况下，处理电路可以被配置为从磁场测量传感器接收表示磁场强度的变化的电压信号，并且基于所述电压信号确定所述笔尖组件受到的压力。更具体地，由于磁性器件102形成的空间磁场不是均匀磁场，磁性器件102的移动会引起磁场测量传感器所处区域的磁场强度发生变化，从而改变了磁场测量传感器的输出电压，处理电路通过检测磁场测量传感器的输出电压，从而可以间接识别出笔尖组件受到的压力。In the case where the magnetic sensing device 103 is configured as a Hall device for inducing a magnetic field strength of a magnetic field around the magnetic device 102, the processing circuit may be configured to receive a voltage signal representing a change in magnetic field strength from the magnetic field measuring sensor, and based on The voltage signal determines the pressure experienced by the nib assembly. More specifically, since the spatial magnetic field formed by the magnetic device 102 is not a uniform magnetic field, the movement of the magnetic device 102 causes a change in the magnetic field strength of the region where the magnetic field measuring sensor is located, thereby changing the output voltage of the magnetic field measuring sensor, and the processing circuit detects the magnetic field. The output voltage of the sensor is measured so that the pressure applied to the nib assembly can be indirectly recognized.

根据本申请的另一个实施例，磁感器件103可以包括通过感应电感值的变化来感应磁性器件103周围的磁场的电感装置，该电感装置与处理电路电连接。According to another embodiment of the present application, the magnetic sensing device 103 may include an inductive device that induces a magnetic field around the magnetic device 103 by sensing a change in inductance value, the inductive device being electrically coupled to the processing circuit.

在磁感器件103被配置为通过感应电感值变化来感应所述磁性器件周围的磁场的电感装置的情况下，处理电路被配置为从电感装置接收表示磁场变化的电感值变化信号，并且基于电感值变化信号确定笔尖受到的压力。更具体地，因为电感装置中电感器的感值与其内部磁通量有密切关系，当磁性器件102由于弹性组件101的形变发生微小的移动时，磁性器件102周围的磁场会使电感器的内部磁通量发生剧烈变化，从而导致电感量发生改变。处理电路通过获得电感器的电感值变化量就能得知磁性器件的位置，从而确定笔尖组件受到的压力。In the case where the magnetic sensing device 103 is configured to sense an inductive device that senses a magnetic field around the magnetic device by sensing a change in inductance value, the processing circuit is configured to receive an inductance value change signal representative of the magnetic field change from the inductive device, and based on the inductance The value change signal determines the pressure on the tip of the pen. More specifically, since the inductance of the inductor in the inductive device is closely related to its internal magnetic flux, when the magnetic device 102 is slightly moved due to the deformation of the elastic member 101, the magnetic field around the magnetic device 102 causes the internal magnetic flux of the inductor to occur. Drastic changes, resulting in changes in inductance. Processing circuit by obtaining The amount of change in the inductance of the inductor tells the position of the magnetic device to determine the pressure applied to the nib assembly.

以上描述了处理电路对于接收到的表示压力的电信号的处理示例，但本申请不限于此。当磁感器件为能够感测磁场的其他器件时，处理电路也可以基于磁感器件的感测对于接收到的表示压力的电信号的进行相应的处理(例如分析笔尖组件受到的压力的变化等)以确定笔尖组受到的压力，其具体处理方式是本领域技术人员可以预见的，在此不再赘述。The processing example of the processing circuit for the received electrical signal representing the pressure has been described above, but the application is not limited thereto. When the magnetic sensing device is another device capable of sensing a magnetic field, the processing circuit may also perform corresponding processing on the received electrical signal representing the pressure based on the sensing of the magnetic sensing device (eg, analyzing changes in pressure received by the nib assembly, etc.) The specific pressure of the pen tip group is determined by those skilled in the art, and details are not described herein.

根据本申请的一个实施例，压力检测装置10还可以包括：用于调节磁性器件212与磁感器件213之间的间隔的调节单元，该调节单元位于磁感支撑件214上。According to an embodiment of the present application, the pressure detecting device 10 may further include: an adjusting unit for adjusting a spacing between the magnetic device 212 and the magnetic sensing device 213, the adjusting unit being located on the magnetic sensing support 214.

图6示出了根据本申请的压力检测装置的另一种示例性结构。Fig. 6 shows another exemplary structure of a pressure detecting device according to the present application.

除了包括图5中的弹性组件211、磁性器件212、磁感器件213和磁感支撑件214之外，压力检测装置还可以包括：调节单元，位于磁感支撑件214上并且位于磁感器件213的两侧.该调节单元可以通过改变其位置对容置在其中的磁感器件213的位置进行调节，从而改变磁性器件212与磁感器件213之间的间隔。根据本申请的实施例，调节单元可以被配置为根据磁感器件213对于磁场的感应来对磁性器件212与磁感器件213之间的间隔进行调节，以使得磁感器件213能够检测由磁性器件212形成的磁场的变化。In addition to including the elastic component 211, the magnetic device 212, the magnetic sensing device 213, and the magnetic sensing support 214 in FIG. 5, the pressure detecting device may further include: an adjusting unit located on the magnetic sensing support 214 and located in the magnetic sensing device 213 The two sides of the adjustment unit can adjust the position of the magnetic sensing device 213 housed therein by changing its position, thereby changing the interval between the magnetic device 212 and the magnetic sensing device 213. According to an embodiment of the present application, the adjustment unit may be configured to adjust an interval between the magnetic device 212 and the magnetic sensing device 213 according to the induction of the magnetic field by the magnetic sensing device 213, so that the magnetic sensing device 213 can detect the magnetic device The change in the magnetic field formed by 212.

更具体地，如图6所示，调节单元可以包括：弹性体215a，位于磁感支撑件214上并且抵靠磁感器件213的一侧；用于使弹性体215a形变来调节磁感器件213的位置的调节件215b，调节件215b抵靠磁感器件213的另一侧并且与弹性体215a一起用于容置磁感器件213。例如，该调节件215b可以通过抵靠磁感器件213的另一侧使弹性体215a形变来改变位于磁感器件213的位置，从而调节磁感器件213与磁性器件212之间的间隔。More specifically, as shown in FIG. 6, the adjustment unit may include an elastic body 215a on a side of the magnetic induction support 214 and abutting against the magnetic sensing device 213; for deforming the elastic body 215a to adjust the magnetic sensing device 213 The adjusting member 215b of the position, the adjusting member 215b abuts against the other side of the magnetic sensing device 213 and is used together with the elastic body 215a for accommodating the magnetic sensing device 213. For example, the adjusting member 215b can pass through The other side of the magnetic sensing device 213 deforms the elastic body 215a to change the position of the magnetic sensing device 213, thereby adjusting the interval between the magnetic sensing device 213 and the magnetic device 212.

根据本申请，可以在设计压力检测装置20时，为磁性器件212和磁感器件213之间的距离X预留部分调节量，在将各个部件装配在一起之后，可以通过调节单元对磁性器件212与磁感器件213之间的距离进行调节，更具体地，通过调节件215b沿磁感支撑件214的轴向移动推动磁感器件213移动、从而使弹性体215a变形，来控制磁性器件212与磁感器件213之间的距离X，以保证每只主动笔的初始状态的一致。According to the present application, a partial adjustment amount may be reserved for the distance X between the magnetic device 212 and the magnetic sensing device 213 when the pressure detecting device 20 is designed, and after the components are assembled together, the magnetic device 212 may be passed through the adjusting unit. The distance between the magnetic sensing device 213 and the magnetic sensing device 213 are adjusted, and more specifically, the magnetic device 212 is moved by the movement of the adjusting member 215b along the axial direction of the magnetic sensing support 214, thereby deforming the elastic body 215a, thereby controlling the magnetic device 212 and The distance X between the magnetic sensing devices 213 is to ensure the consistency of the initial state of each active pen.

如图6所示，弹性体215a可以设置为“L”型，并且弹性体215a可以被放置磁感支撑件214的凹槽内，从而可以将磁感器件213放置在弹性体215a的凹处，通过调节件215b使磁感器件213向靠近磁性器件212的方向移动，从而使得弹性体215a压缩变形，从而改变磁性元件213的位置，使得磁感器件213与磁性器件212之间的距离X变小。As shown in FIG. 6, the elastic body 215a may be disposed in an "L" shape, and the elastic body 215a may be placed in the recess of the magnetic induction support 214, so that the magnetic sensing device 213 may be placed in the recess of the elastic body 215a. The magnetic sensing device 213 is moved toward the magnetic device 212 by the adjusting member 215b, so that the elastic body 215a is compressively deformed, thereby changing the position of the magnetic member 213, so that the distance X between the magnetic sensing device 213 and the magnetic device 212 becomes small. .

根据本申请的一个实施例，在主动笔被装配好之后且在主动笔使用之前，可以根据磁感器件213感测到的磁场强度，对磁感器件213与磁性器件212之间的距离进行调节。例如，当磁感器件213感测到的磁场强度达到磁场强度预定值以上，可以使调节单元停止对于磁感器件213位置的调节，从而将磁感器件213和调节单元的位置固定。在使用主动笔时，通过位置固定的磁感器件213感测磁性元件212形成的磁场变化(即，由于弹性组件211的伸缩和/或偏转导致的、磁性元件形成的磁场变化)。在本申请中，磁场强度预定值可以由本领域技术人员根据主动笔的灵敏度要求而任意设置。According to an embodiment of the present application, the distance between the magnetic sensing device 213 and the magnetic device 212 can be adjusted according to the magnetic field strength sensed by the magnetic sensing device 213 after the active pen is assembled and before the active pen is used. . For example, when the magnetic field intensity sensed by the magnetic sensing device 213 reaches a predetermined value of the magnetic field strength, the adjustment unit may be stopped from adjusting the position of the magnetic sensing device 213, thereby fixing the position of the magnetic sensing device 213 and the adjusting unit. When the active pen is used, the change in the magnetic field formed by the magnetic member 212 (i.e., the change in the magnetic field formed by the magnetic member due to the expansion and/or deflection of the elastic member 211) is sensed by the positionally fixed magnetic sensing device 213. In the present application, the predetermined value of the magnetic field strength can be arbitrarily set by a person skilled in the art according to the sensitivity requirement of the active pen.

由于在压力检测装置中配置了能够调节磁性器件212与磁感器件213之间间隔的调节单元，因此降低了压力检测装置内的各个零件精度和装配公差要求，并且通过调节单元的移动来控制磁性器件212与磁感器件213之间的间隔，使得每只主动笔的初始状态能够保持一致性。Since the magnetic detecting device and the magnetic sensing device 213 can be adjusted in the pressure detecting device The inter-spaced adjustment unit thus reduces the individual part accuracy and assembly tolerance requirements within the pressure sensing device and controls the spacing between the magnetic device 212 and the magnetic sensing device 213 by the movement of the adjustment unit such that the initial of each active pen The state is consistent.

根据本申请，可以将参考图5-6描述的压力检测装置20的主板与支撑架螺纹连接，来保证在主动笔使用或跌落时具有良好的稳定性。According to the present application, the main board of the pressure detecting device 20 described with reference to FIGS. 5-6 can be screwed to the support frame to ensure good stability when the active pen is used or dropped.
