Description

加强笔头及压感笔 技术领域
本发明涉及输入设备领域，特别涉及一种加强笔头及压感笔。
背景技术
目前，市场上的大尺寸平板电脑为了满足防眩光需求，大部分都采用了AG(抗反射)玻璃面制作显示屏以提高显示画面的可视角度和亮度，故显示屏的表面粗糙度较高。而能够在AG玻璃表面长期书写的材料并不多，PE(聚乙烯)是其中的一种主流材料。
如图1所示，PE材料制成的笔头外表面是烧结成型的，因而具有良好的耐磨耐冲击特性。制作笔头受现有模具技术的限制，尾部需要脱模，故尾部会崎岖不平，容易碎裂，不可以直接受力。故传统的白板笔笔头一般采用过盈配合安装在笔杆上，使笔头书写时，主要是笔头侧边受到摩擦力，尾部受力小，以确保笔头拥有较长的使用寿命。
如图2所示，当这类笔头应用到压感笔上时，笔头需要经常往复活动，尾部经常会受不均匀冲击。由于压感笔结构的限制，笔头的尾部也往往需要制作成细杆状，更容易碎裂失效。另外此类笔头原材料为白色，如果有外观需求，则需要进行染色处理。染色时需要将外表面烧结后的PE材料置于染色炉内不断受压翻滚以确保染色均匀，染色操作同样容易导致笔头的尾部受损。
发明内容
基于此，本发明在于克服现有技术的缺陷，提供一种加强笔头及压感笔，具有更高的强度和更长的使用寿命。
其技术方案如下：
一种加强笔头，包括笔头主体、托盘及顶杆，所述笔头主体设置在托盘的一侧，所述托盘上设有安装孔，所述笔头主体上设有凸柱，所述凸柱卡设在安装孔内并与托盘固定连接，所述顶杆设置在托盘的另一侧并与托盘相连接。
在其中一个实施例中，所述凸柱与托盘的连接处设有胶水粘合层。
在其中一个实施例中，所述托盘上还设有溢胶孔，所述溢胶孔与安装孔连通。
在其中一个实施例中，所述溢胶孔为多个，多个溢胶孔均匀分布在托盘上。
在其中一个实施例中，所述凸柱与安装孔过盈配合。
在其中一个实施例中，所述托盘与顶杆为一体成型结构。
在其中一个实施例中，所述托盘由ABS塑料制成，所述笔头主体由PE塑料制成。
本发明还提供一种压感笔，包括笔杆、压力传感器及如权利要求1-6任一项所述的加强笔头，所述笔杆内设有容纳腔，所述笔杆的一端具有供所述顶杆插入的配合孔，所述配合孔与容纳腔连通，所述压力传感器设置在容纳腔内并与顶杆抵接。
在其中一个实施例中，所述压感笔还包括套设在顶杆上的导向套，所述导向套固定在容纳腔内。
在其中一个实施例中，所述导向套由弹性材料制成。
下面对前述技术方案的优点或原理进行说明：
制作上述加强笔头时，将烧结成型的笔头主体尾部制成与托盘上的安装孔匹配的凸柱，然后将凸柱卡设在安装孔内实现组装，由于凸柱受力小，因而能有效提高使用寿命。另外，在染色时只需要将笔头主体置于染色炉内进行处理，无需对顶杆染色，避免顶杆受损，从而提高了整体强度和产品良率。将上述加强笔头应用于压感笔上时，能进一步提高压感笔的整体强度和使用寿命。

具体实施方式
下面对本发明的实施例进行详细说明：
如图3-5所示，本实施例所述的加强笔头，包括笔头主体1、托盘2及顶杆3，所述笔头主体1设置在托盘2的一侧，所述托盘2上设有安装孔20，所述笔头主体1上设有凸柱10，所述凸柱10卡设在安装孔20内并与托盘2固定连接，所述顶杆3设置在托盘2的另一侧并与托盘2相连接。制作上述加强笔头时，将烧结成型的笔头主体1尾部制成与托盘2上的安装孔20匹配的凸柱10，然后将凸柱10卡设在安装孔20内实现组装，由于凸柱10受力小，因而能有效提高使用寿命。另外，在染色时只需要将笔头主体1置于染色炉内进行处理，无需对顶杆3染色，避免顶杆3受损，从而提高了整体强度和产品良率。
在本实施例中，所述凸柱10与托盘2的连接处设有胶水粘合层4。在凸柱10与托盘2之间填充胶水，胶水能够渗入凸柱10崎岖不平的部分，使笔头主体1与托盘2可靠固定，同时能够均匀释放笔头主体1受到的轴向冲击力。所述托盘2上还设有溢胶孔21，所述溢胶孔21与安装孔20连通。往凸柱10与托盘2之间填充胶水时，多余的胶水能够从溢胶孔21中排出。此外，溢胶孔21还具有排气作用，方便笔头主体1安装。本实施例所述的溢胶孔21为多个，多个溢胶孔21均匀分布在托盘2上，以便多余的胶水能顺利排出。
本实施例所述的凸柱10与安装孔20过盈配合，能够进一步减小笔头主体1的受力，提高使用寿命。优选地，所述托盘2与顶杆3为一体成型结构，提高结构强度。其中，本实施例所述的托盘2由ABS塑料制成，强度高、韧性好、易于加工成型。所述笔头主体1由PE塑料制成，能实现显示屏AG玻璃面的顺滑书写。
如图6所示，本发明还提供一种压感笔，包括笔杆5、压力传感器6及如权 利要求1-6任一项所述的加强笔头，所述笔杆5内设有容纳腔50，所述笔杆5的一端具有供所述顶杆3插入的配合孔，所述配合孔与容纳腔50连通，所述压力传感器6设置在容纳腔50内并与顶杆3抵接。将上述加强笔头应用于压感笔上时，能进一步提高压感笔的整体强度和使用寿命。
在本实施例中，所述压感笔还包括套设在顶杆3上的导向套7，所述导向套7固定在容纳腔50内，维持笔头主体1的活动方向。本实施例所述的导向套7由弹性材料制成，避免笔头主体1活动时发生卡顿。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
