下面结合附图，对本发明的一些实施方式作详细说明。在不冲突的情况下，下述的实施例中的特征可以相互组合。
实施例一：
本实施例提供了的一种便携式打印机，如图1-9所示，该便携式打印机包括座体2和覆盖在该座体2顶部的盖体1；所述座体2内配置有：沿竖直方向配置的打印头5以及与所述打印头5对置的压纸辊209，所述压纸辊209绕第一轴线旋转。竖直方向是指在打印机放置在水平台面上时打印头5的延伸方向，也即打印机的高度方向。压纸辊209通过在与所述打印头5之间夹持有记录纸的状态下进行旋转来将所述记录纸送出；所述座体2内配置有，响应于所述盖体1的开合盖动作而驱动所述打印头5靠近或远离压纸辊209的致动杆4；其中所述致动杆4配置为，围绕平行于所述第一轴线的第二轴线摆动，第一轴线和第二轴线为两个位置不同的轴线，并且第一轴线和第二轴线均为竖直方向上的轴线。所述致动杆4具有用于安装打印头5的安装部和由座体2内伸出以受盖体1驱动的驱动部401，驱动部401位于致动杆4的端部；所述盖体1上具有能够抵压所述驱动部401以驱动所述致动杆4摆动的抵接部101a，抵接部101a位于盖体1的内侧面上，在完成合盖后，抵接部101a为不可见。上述打印头5和压纸辊209的夹持力来自盖体1对致动杆4的保持力。
需要说明的是，本实施例中的打印头5为热敏打印头，其包括热敏元件和用于安装热敏元件的打印头支架。相应地，记录纸也为热敏纸。但这并不构成对本实用新型的限制，在其它实施例中也可以采用其它类型的打印头。
如图5和图6所示，在所述盖体1合盖时，所述抵接部101a抵压所述驱动部401以驱动所述致动杆4摆动，并在所述致动杆4摆动过程中，所述打印头5靠近所述压纸辊209。在所述致动杆4和座体2之间配置有施力件212，该施力件212配置为，使得所述打印头5远离于压纸辊209的方向施力于所述致动杆4。在所述盖体1开盖时，所述抵接部101a释放所述驱动部401，所述施力件212驱动所述致动杆4摆动，并在所述致动杆4摆动过程中，所 述打印头5远离所述压纸辊209。所述座体2上具有沿所述第二轴线上延伸的枢接轴213，所述致动杆4上形成有枢接孔，所述枢接孔和枢接轴213相适配以使得所述致动杆4枢转连接在座体2上。所述施力件212为配置在枢接轴213上的扭簧，该扭簧的至少一个支脚连接至所述致动杆4以向致动杆4施力。具体地，枢接轴213的顶部具有一个凹口，扭簧的主体固定在凹口内，并且该扭簧具有两个支脚，一个支脚卡接固定在枢接轴213上，另一个支脚卡接固定在致动杆4上，以施力于致动杆4上，使致动杆4在失去盖体1的作用力后可以回复至初始位置。在盖体1打开后，打印头5和压纸辊209之间的间隙达到最大，可以方便用户将记录纸取出，以进行更换。
需要说明的是，在其它的实施例中，施力件212也可以选用弹簧或弹片，如选用弹簧或弹片作为施力件212，则在致动杆4上靠近驱动部401的位置或者是靠近安装部的设置弹簧或弹片，使抵接部101a在与驱动部401抵压作用时需要克服弹簧或弹片的弹力才可以驱动致动杆4摆动即可，当然可以理解的是，本实施例中采用扭簧作为施力件212是一种最优的方式，一方面扭簧设于枢接孔中、套设于枢接轴213上无需额外占用座体2内的空间，另一方面，由于致动杆4的动作过程属于摆动，扭簧可以比弹簧或弹片更好的适应摆动，不易发生失效等损坏，减少故障次数。
进一步地，盖体1通过转轴转接在座体2上，并且在转轴上套接有开盖扭簧，该开盖扭簧的第一支脚抵接在座体2上，第二支脚抵接在盖体1上，主体部分套接在转轴上。在合盖过程中，盖体1上的抵接部101a抵压致动杆4的驱动部401，使得致动杆4围绕第二轴线摆动，在致动杆4摆动过程中，打印头5逐渐靠近压纸辊209。在打印头5抵压在压纸辊209上时，二者之间夹持有记录纸，电机210通过传动机构211驱动压纸辊209旋转，从而实现记录纸的进给。在开盖过程中，致动杆4的抵接部101a逐渐释放驱动部401，致动杆4在施力件212的作用下反转，从而使打印头5远离压纸辊209。图1示出了打印机的合盖状态，图2示出了打印机的开盖状态。
与现有技术中用于驱动打印头靠近或远离压纸辊的致动机构相比，本申请中的致动杆结构简单，所需的传动机构较少，无需多次传动、更无需使用较多的弹性元件来驱动致动机构复位，因此本实施例提供的该便携式打印机中的致动杆结构更简便、动作更直接有效、占用空间更小，可以更好地满足小型化、便携的使用需求。且由于传动机构较少，发生故障的次数就会减少，更不容易损坏，同时后期的维修更换更加方便。
如图7和图8所示，致动杆4的安装部内形成有安装腔，所述打印头5配置在该安装腔内。安装腔为由致动杆4的端部向内侧凹进的凹腔，致动杆4的端部具有一个开口，打印头5由该开口装入在安装腔内。所述安装部内设置有用于抵压打印头5的弹性件6，该弹性件6为圆柱弹簧。所述弹性件6朝向所述打印头5靠近所述压纸辊209的方向施力于打印头5，以使得所述打印头5抵靠在压纸辊209上时二者的间隙能够适应于所述记录纸的厚度，从而可以适应更多厚度范围内的纸张，以避免在纸张较厚时无法通过打印头5和压纸辊209之间的间隙，也即走纸通道。具体地，圆柱弹簧的两端分别抵触在打印头5上和安装腔的腔壁上。
在本实施例中，所述打印头5和安装部之间通过滑动结构接合，也即打印头5可以在安装腔内上下浮动，所述滑动结构包括设置在打印头5左右两侧的滑块和设置在安装部左右两侧壁上的滑槽，左右两侧的滑块伸入滑槽内，滑块和打印头5支架一体设置，并能够在滑槽内上下滑动。所述安装部的底壁上设置有用于支撑打印头5、并限定打印头5位置的限位凸起，该限位凸起位于打印头5支架的尾部。在打印过程中，该限位凸起和压纸辊209共同形成对打印头5的稳定支撑。
进一步地，为了实现结构紧凑，所述致动杆4设置为开口背向于所述压纸辊209的略V字形，如图6-8所示，安装部设于致动杆4上靠近压纸辊209的一端，驱动部401设于致动杆4上远离压纸辊209的一端，该驱动部401是由致动杆4的杆体向其侧向延伸形成，第二轴线位于致动杆4上的折弯处，也即，安装部和驱动部分别位于致动杆上相对于第二轴线的不同侧。具体的，在座体2上设有沿第二轴线延伸的枢接轴213，在致动杆4上该折弯处形 成有枢接孔，枢接孔和枢接轴213相适配以使得致动杆4枢转连接在座体2上；盖体1上设有转动部，座体2上设有转轴，盖体1通过转动部与转轴配合转动盖合在座体2上，在转动部上形成有用于抵压驱动部401的抵接部101a，相应的，所述驱动部设置为与所述抵接部相适应的凸块。第一罩壳201上具有一个供驱动部401伸出的窗口201a，驱动部401由该窗口201a伸出所述第一罩壳201，以使得在合盖过程中，盖体1能够抵压该驱动部401使致动杆4绕第二轴线摆动。
如图5和图6所示，所述座体2内设置有用于驱动压纸辊209转动的纸辊驱动装置，所述纸辊驱动装置包括驱动电机210和传动机构211，所述驱动电机210安装在所述致动杆4的开口一侧，并且所述驱动电机210的中心轴线和第二轴线平行。所述座体2内配置有垂直于所述第二轴线的内衬板205，所述驱动电机210和传动机构211分别设置在内衬板205的上下两侧。具体地，传动机构211包括多个相互啮合传动的齿轮，在其它实施方式中还可以是其它传动机构211，例如皮带传动机构211。电机210可以通过传动机构211将动力传递至压纸辊209上，使得压纸辊209转动。在压纸辊209转动时可以带动记录纸移动实现记录纸的进给。电机210和传动机构211分别位于内衬板205的上下两侧有利于使得整机的结构更为紧凑。
如图4所示，所述座体2内安装有第一罩壳201，所述第一罩壳201和内衬板205之间形成第一腔室，所述驱动电机210和致动杆4均配置在第一腔室内。所述座体2内安装有第二罩壳202，所述第二罩壳202和内衬板205之间形成第二腔室，所述压纸辊209配置在第二腔室内，并且所述压纸辊209的两端部分别可转动地结合在第二罩壳202和内衬板205上。上述配置有利于使得整体结构紧凑。在本实施例中，外壳203是有底的筒形结构，内衬板205是由外壳203的顶部开口装入外壳203中，第一罩壳201和第二罩壳202均可拆卸地安装在内衬板205上。
进一步参考图4所示，所述座体2内安装有开口向下并扣置在内衬板205上的第一罩壳 201和第二罩壳202，所述致动杆4配置在第一罩壳201内，所述压纸辊209配置在第二罩壳202内，所述第一罩壳201和第二罩壳202之间形成有用于走纸的走纸间隙，打印头5和压纸辊209分置在走纸间隙的两侧。所述座体2具有用于构成其底壁和侧壁的外壳203，所述第一罩壳201、第二罩壳202和外壳203的侧壁共同围设成用于安装纸卷的纸仓204。该种纸仓204的形成结构既可以使得纸仓204的容积最大，放入更多的记录纸，还使得结构简单，便于安装。
如图3和图5所示，所述座体2内配置有内衬板205，所述内衬板205和外壳203的底壁之间形成第三腔室，所述第三腔室内安装有电池206和电路板207。具体地，电池206为可充电电池206，所述第三腔室内安装有电路板207，所述电路板207和电池206之间设置有隔板208，隔板208可以防止在工作过程中，电池206产生的热量传递至电路板207上，影响电路板207的正常工作。隔板208通过螺钉固定在内衬板205上，电池206也固定在内衬板205上，电路板207固定在隔板208上。
如图3和图9所示，所述盖体1包括内盖101和外盖102，所述内盖101上配置有用于限制纸卷向上窜动的限位部101b，以防止在打印过程中因纸卷跳动产生的卡纸问题。
如图10所示，为方便内衬板205的装配，本实施例中还在所述座体内侧壁沿打印机高度方向设有导向限位板203a，并在内衬板205上设有与所述导向限位板相适配的缺口槽205a，所述导向限位板203a与缺口槽205a相配合以引导内衬板装入容纳腔并对内衬板限位。也即在装配内衬板时，可将内衬板上的缺口槽对准座体内的导向限位板插入，内衬板装配到位后，也可以利用导向限位板与缺口槽来防止内衬板沿水平方向晃动。
如图11所示，为进一步减薄打印机整体的设计厚度，本实施例中还在内衬板上在打印头摆动区域内设有下沉槽205b，以增加打印头摆动区域内沿竖直方向上的容纳高度，也即在内衬板上的上述区域内减薄内衬板自身的厚度，以便于在打印头长度确定的前提下，可以减薄打印机整体的厚度。进一步的，结合图2、图4和图5中所示，本实施例中还在第一罩壳201 上在打印头摆动区域内向上凸出形成有上凸槽201b，以增加打印头摆动区域内沿竖直方向上的容纳高度，也即在第一罩壳上的上述区域内向上凸出形成一定的容纳空间，以便于在打印头长度确定的前提下，可以减薄打印机整体的厚度。
另外，所述致动杆4上设置检测开关，所述第二罩壳202内设置有触发件；或者所述第二罩壳202内设置有检测开关，所述致动杆4上设置有触发件；在所述打印头5接近压纸辊209时，所述触发件触发检测开关产生电信号。所述触发件为磁石，所述检测开关为霍尔元件。在打印头5靠近压纸辊209时，磁石触发霍尔元件产生电信号，以用来判断是否合盖到位，以及打印头5和压纸辊209之间的间隙是否处于适合打印的状态，避免浪费记录纸。
进一步地，还可以设置用于检测在走纸通道中是否有记录纸的检测装置，该检测装置可以是两个对置的红外线传感器，在走纸通道中有纸时，记录纸遮挡住红外线发生器产生的红外线，使得红外线接收器不能接收到红外线，从而实现纸张的判定。
进一步地，为了判断盖体1的开合盖状态，在又一实施例中的盖体1上设置有磁石，在第二罩壳202的内侧设置有霍尔元件。当盖体1处于合盖状态时，磁石可以触发霍尔元件，控制装置判定为合盖状态。当盖体1处于开盖状态时，磁石远离霍尔元件，霍尔元件处断开状态，控制装置判定为开盖状态。
本发明的工作过程如下：
在使用是，打开盖体1，将记录纸的纸卷放入纸仓204内。此时打印头5和压纸辊209之间的间隙最大，可以将记录纸由走纸通道中引出，然后合上盖体1，在合盖过程中，盖体1上的抵接部101a抵压在驱动部401上，使致动杆4转动以使得打印头5靠近压纸辊209，并将记录夹持在二者之间的间隙内。在电机210驱动压纸辊209转动时，可以实现一边打印边一边进给记录纸。在完成打印后，用户可以通过设置在走纸通道开口处的切刀切断记录纸。在纸仓204内缺纸时，可以打开盖体1进行更换。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉 本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
