可选地，后盖120与表框110可以通过一体成型工艺制成一体结构，进而能够简化手表结构，提高生产效率。并且由于后盖120与表框110之间将不存在结合间隙，还能够提高手表的整体防水效果。
例如，该一体成型工艺可以是铸造、烧结、注塑或者3D打印技术等，但不限于此。
显示屏500用于提供用户与智能手表的人机交互，例如向用户展示信息(例如时间、新闻、天气等信息)或者接收用户输入的信息(例如接收用户的控制指令)。
可选地，显示屏500可以是触摸屏，例如可以是液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，Miniled，MicroLed，Micro-oLed，量子点发光二极管(quantum dot light emitting diodes，QLED)显示屏等，但不限于此。
显示屏500固定安装于壳体100之上，以形成用于容纳表芯200的容纳腔体(即手表内腔)。表芯200是智能手表的主体部分，表芯200可以由多个电子元件集合而成。本申请实施例对表芯200的具体构成不作特殊限定，例如表芯200可以由智能手表内部的任意一个或者多个元器件组合而形成。图2和图3中示出的表芯200仅作为示意，例如，实际应用中表芯200可以由多个部件集合而形成实心的盘状结构，而非图中的中空结构。
如图1-图3所示，本申请实施例提供的智能手表还包括设于表框110外壁上的按键300。按键300与内部的表芯200相连接，能够用来对智能手表进行功能调节，例如能够用来调节时间、开关机、调节扬声器播放音量、调节显示屏亮度等。按键300能够被旋转或者按压，以实现上述各个功能。
如图2和图3所示，按键300从智能手表的外部穿入到智能手表的内部，并且与表芯200相连接，进而能够实现上述调节功能。表芯200固定设于表框110内，表框110上开设有第一按键孔111，表芯200上设有与第一按键孔111相对的第二按键孔210，上述两个按键孔用于供按键300的按键杆插入。
本申请实施例主要涉及对按键300的结构进行改进，提供了一种新的按键设计方 案，使得表芯200能够从表框110中拆卸出去，同一个表芯200能够搭配不同颜色或者造型的多个表框110进行使用，进而使得智能手表具有较佳的用户体验感，并且也能够方便对智能手表进行维修。
图4是本申请实施例提供的智能手表的按键300的连接结构图。图5是图2中按键部分的局部放大图。图6是本申请实施例提供的智能手表的按键300的一例的装配结构图。图7是图6所示结构的爆炸图。
如图4-图7所示，在本申请实施例中，按键300包括按键帽310、第一按键杆320和第二按键杆330，按键帽310与第一按键杆320固定相连，第一按键杆320设于第一按键孔111内，第二按键杆330设于第二按键孔210内。
通过按键帽310调节第一按键杆320的位置可使按键300进入工作状态或者拆卸状态。当按键300处于工作状态，第一按键杆320与第二按键杆330相互接合(对接)，第二按键杆330能够传递来自所述按键帽310的压力或者转矩；当按键300处于拆卸状态，第一按键杆320与第二按键杆330相互分离，此时二者之间产生间隙，表芯200能够被从表框110内取出。
根据本申请实施例提供的智能手表，按键300的按键杆由相互独立的两个部分组成，即按键300包括第一按键杆320和第二按键杆330，第一按键杆320设于表框110上的第一按键孔111内，第二按键杆330设于表芯200上的第二按键孔210内。第一按键杆320和第二按键杆330能够相互接合以使按键300进入工作状态，或者上述二者也可以相互分离以使按键300进入拆卸状态。
用户可以通过按键帽310调节第一按键杆320的位置进而使按键300进入工作状态或者拆卸状态。例如，用户可以通过按压按键帽310使第一按键杆320向表内缩入，进而使第一按键杆320与第二按键杆330相互接合(对接)，第二按键杆330能够传递来自所述按键帽310的压力或者转矩，此时按键300进入工作状态，能够正常进行调节工作，用户可以通过旋转或者按压按键300来对智能手表进行调节。
本申请实施例提供的按键300还具有拆卸状态，用户可以通过按键帽310将第一按键杆320向表外拉拔以使按键300进入拆卸状态。即本申请中的按键300能够实现按压、旋转以及拉拔三种动作。当用户通过按键帽310向外拉拔第一按键杆320时，第一按键杆320与第二按键杆330相互分离，二者之间产生间隙，不再接触，表芯200和表框111相互独立，此时按键杆不再构成阻碍，用户能够将表芯200从表框110内取出。使得同一个表芯200能够搭配不同颜色或者造型的多个表框111进行使用，进而使得智能手表具有较佳的用户体验感，并且也能够方便对智能手表进行维修。
本申请实施例提供的智能手表可以具有多个表框111，该多个表框111的颜色或者造型可以不同，多余的表框111可以作为智能手表的配件一同进行售卖，或者由用户自住选购。通过前述按键300的结构，用户能够方便高效的将表芯200从表框111中拆下，并且装入到其他的表框111中。用户可以根据实际场景将表芯200搭配不同的表框111进行使用，能够满足用户对于产品外观形态差异化个性化的需求，使得本申请实施例提供的智能手表更加具有市场竞争力。
值得一提的是，当按键300进入拆卸状态时，第一按键杆320和第二按键杆330相互分离并且独立，此时表芯200能够被从表框110内取出。而为了实现这一目的， 此时第一按键杆320的内端不应伸入第二按键孔210内，并且第二按键杆330的外端不应伸入第一按键孔111内。
在一种可能的实现方式中，表芯200包括表芯壳250和前述的显示屏500，显示屏500固定盖合于表芯壳250的开口之上，并形成一体结构，主板、蓄电池、扬声器等多个电子元件均设置于该一体结构的内部，第二按键孔210开设于表芯壳250之上。此时，壳体100相当于能够容纳表芯200的表托，当表芯200被从壳体100上取下时，表芯200类似于传统意义上的怀表，此时表芯200能够被单独进行使用，用户可以将表芯200收纳于口袋中，或者通过线绳悬挂于脖子上，满足用户的个性化使用需求。
如图3-图5所示，表芯200还包括位于表芯壳250内的安装支架220、按键开关230和旋转检测传感器240。其中，安装支架220固定安装于表芯壳250内，按键开关230安装于安装支架220上，用于供第二按键杆330的内端进行按压，按键开关230包括用于使第二按键杆330复位的弹片231。第二按键杆330的端部挤压弹片231，进而触发按键开关230发出相应信号，实现按键功能。旋转检测传感器240安装于安装支架220上，用于检测第二按键杆330的旋转角度。
在这里，按键开关230用于检测用户的按压动作，按键开关230可以通过点胶、定位孔与背胶、卡扣等方式安装于安装支架220之上，并且与第二按键杆330相互正对，用于在第二按键杆330被按压后受第二按键杆330触发而导通。按键开关230具有弹片231，弹片231通过热熔柱安装固定在安装支架220上，通过热熔柱对弹片231进行限位。
安装过程中，弹片231通过导向角与第二按键杆330过盈配合。未按压状态下，弹片231具有初始过盈量，用于按键300的初始反弹力。反弹力不能过大，导致手感偏硬，也不能过小，按压过程会出现空行程或第二按键杆330不回弹的风险。按压过程中按键300的弹力由弹片231提供。弹片231在一定按压次数下，不发生塑性变形。
此外，弹片231与第二按键杆330的内端相抵接，在按键300被旋转时，能够向用户提供阻尼感，并且在旋转过程中，弹片231与第二按键杆330的摩擦具有对称性，正反转阻尼力一致性好。
可选地，弹片231的材料为SUS 301EH，通过设计合适的弹力臂，给按键300回弹提供合适的弹力，并且提高其抗疲劳能力。
可选地，弹片231为单弹力臂形式，能够减小空间，降低长期腐蚀风险，弹片231有足够的臂长，避免其在长期的按压过程中，产生塑性变形。
可选地，按键开关230可以为顶盖开关(dome)。
旋转检测传感器240可以是用于检测第二按键杆330旋转的任何合适类型的传感器，如激光传感器、霍尔传感器等。旋转检测传感器240位于柔性电路板(flexible printed circuit，FPC)上，并且通过热熔柱固定在安装支架220上。
在一些情况下，第二按键杆330的内端的外表面可以做成粗糙表面，也即第二按键杆330的外周部具有一定的粗糙度，以协助旋转检测传感器240进行检测。
可选地，为了提高检测精度，第二按键杆330的内端可以套设六角螺母，激光传感器发射的光通过六角螺母反射回来，在按键旋转时，激光传感器能够通过不同的反射状况，检测旋转的角度。
如图4-图7所示，第二按键杆330的外周设有定位环槽331b，第二按键杆330通过弹性胶圈331c嵌入第二按键孔210内，弹性胶圈331c套设于第二按键杆330的外周并且位于定位环槽331b内。通过以上设置，能够对第二按键杆330起到一定的限位作用，防止在弹片231的作用下第二按键杆330外伸至第一按键孔111内，并且弹性胶圈331c的设置还能够起到防水隔尘的作用。该弹性胶圈331c与定位环槽331b可以一一对应的设置多对，弹性胶圈331c可以是O型圈，例如可以是橡胶圈。
进一步地，如图3所示，表芯200包括表芯壳250，第二按键孔210开设于表芯壳250上，第二按键杆330内端的外周还凸设有定位凸环331d，该定位凸环331d位于表芯壳250的内侧，能够对第二按键杆330的外伸起到限位作用，防止第二按键杆330外伸至第一按键孔111内，或者防止第二按键杆330从第二按键孔210内脱出。
图8是本申请实施例提供的智能手表的按键300的另一例的装配结构图。图9是图8所示结构的爆炸图。如图8、图9所示，为了协助旋转检测传感器240进行检测，同时为了提高检测精度，第二按键杆330的内端套设六角螺母340，例如二者通过螺纹连接固定，并且六角螺母340的外表面可以做成粗糙表面，例如在外表面设置凹凸不平的纹理，旋转检测传感器240(例如激光传感器)发射的光通过六角螺母340反射回来，在按键旋转时，旋转检测传感器240能够通过不同的反射状况，检测旋转的角度。
如图4-图7所示，本申请实施例提高的智能手表还包括巴管400。巴管400套设于第一按键杆320的外周并且内端固定插入第一按键孔111内。巴管400可通过铆接、螺接、粘接或者焊接中的至少一种方式固定于表框110的外表面上，并且内端伸入第一按键孔111内。例如，巴管400与表框110通过螺纹固定，巴管400旋入第一按键孔111内以后与表框110点焊，防止巴管400被反向扭出。
如图5-图7所示，第一按键杆320包括第一杆体321和连接块322，第一杆体321的一端固定连接于按键帽310之上，例如二者一体成型，第一杆体321的另一端固定套设有连接块322，连接块322滑动穿设于巴管400的内端。按键300能够在巴管400内进行旋转或者按压操作，通过设置连接块322，并且滑动穿设于巴管400的内端，能够提高按键300旋转运动或者伸缩运动的稳定性。
进一步地，如图5-图7所示，连接块322后端面上开设有具有内螺纹的紧固槽322b，第一杆体321的内端的外表面设有与该内螺纹相互配合的外螺纹，连接块322通过紧固槽322b紧固连接于第一杆体321之上。通过以上设置能够方便高效的实现连接块322和第一杆体321的可靠连接。
进一步地，如图5-图7所示，本申请实施例提供的智能手表还包括弹棒410和弹棒支架420。弹棒支架420固定于巴管400的内部并且套设于第一杆体321的外周，弹棒410通过过盈组装在弹棒支架420上，弹棒410用于向第一杆体321提供弹性夹紧力，进而能够对按键300起到更好的定位作用，弹棒410夹紧第一杆体321，还能够在旋转时向用户提供阻尼感。
如图5-图7所示，弹棒支架420呈圆盘状结构，并通过螺纹连接于巴管400的内部。弹棒支架420的中部具有供第一杆体321穿过的通孔，该通孔的孔径略大于第一杆体321的外径，保证第一杆体321能够顺畅转动。
本申请实施例中的按键300具有工作状态和拆卸状态，考虑到按键300的工作场景要远远多于拆卸场景，为了方便用户的使用，工作状态可以是按键300的默认状态，即在不受外力的情况下，第一按键杆320与第二按键杆330保持接合，此时用户可以直接通过按键300对智能手表进行调节。
进一步地，智能手表还包括弹性件，该弹性件的弹力使第一按键杆320与第二按键杆330保持相互接合，即该弹性件将按键300弹性保持于工作状态。当用户需要拆卸表芯200时，用户可以通过按键帽310克服该弹性件的弹力向外拉拔第一按键杆320，进而使得按键300由工作状态转换至拆卸状态。
作为一种可能的实现方式，如图5-图7所示，本申请实施例提供的智能手表还包括弹簧430和垫片440。弹簧430和垫片440均套设于第一杆体321之上，并且被弹性夹紧于连接块322与弹棒支架420之间(即位于弹棒支架420背离弹棒410的另一侧)，弹簧430通过垫片440向连接块322提供弹力，弹簧430的一端与弹棒支架420相抵接，另一端通过垫片440与连接块322的后端面相抵接，进而能够将第一按键杆320压紧于第二按键杆330之上，即将按键300保持在工作状态。
通过以上设置，当表芯200对位安装后，在巴管400内弹簧430作用下连接块322可以快速准确的与第二按键杆330对接，实现按键功能与限位作用，能够将按键300可靠保持在工作状态，方便用户使用。此外，由于有弹簧430的存在按键杆间不是刚性连接，可以防止拆除表芯200时因忘记拉拔按键帽310(表冠)导致按键300被损坏的问题，起到了缓冲作用。
当按键300处于工作状态，第一按键杆320与第二按键杆330相互接合，第二按键杆330能够传递来自按键帽310的压力或者转矩。本申请对第一按键杆320与第二按键杆330的接合方式不作特殊限定，只要能够传递按压力和扭矩即可，例如第一按键杆320与第二按键杆330可以共同构成了一个“离合器”，能够实现接合和分离，进而能够实现动力的传输或者中断，在中断是方便用户将表芯200从表框111中取出。
如图5-图7所示，当按键300处于工作状态，第一按键杆320与第二按键杆330相互插接配合。第一按键杆320与第二按键杆330中的一者上可以设置插头、插块、插柱或者插销等结构，而另一者上可以设置与之配合的插槽或者插孔。
进一步地，在本申请实施例中，连接块322的前端面上设有定位插头322a，使得连接块322整体呈“凸”字形结构，第二按键杆330端面上开设有供定位插头322a插入的第二定位槽331a。自由状态下(即工作状态下)，在弹簧430的作用下，定位插头322a插入第二定位槽331a内，定位插头322a的截面形状为非标准圆形，例如可以为三角形、六边形等，使得第一按键杆320与第二按键杆330之间不仅能够实现按压力的传递，还能够传递扭矩，第一按键杆320能够带动第二按键杆330同步进行旋转。
在其他实现方式中，第一按键杆320与第二按键杆330也可以通过其他方式实现相互接合。图10是本申请实施例提供的智能手表的按键300的再一例的装配结构图。图11是图10所示结构的爆炸图。
如图10、图11所示，当按键300处于工作状态，第一按键杆320与第二按键杆330的端面相抵以产生摩擦力，并且通过摩擦力实现转矩的传递。为了使摩擦力足够大，第一按键杆320与第二按键杆330的端面可以设置的粗糙一些，该摩擦力例如可 以是静摩擦力。
进一步地，本申请实施例提供的智能手表还包括磁性件，该磁性件用于产生磁吸力以增大第一按键杆320与第二按键杆330的端面之间的压力，进而能够增大二者之间的摩擦力，有利于实现扭矩的顺利传递。
如图10、图11所示，在本申请实施例中，连接块322的端面上设有第一定位槽322c，第一按键杆320还包括固定设于第一定位槽322c内的第一磁性件323(例如通过胶粘)；第二按键杆330包括第二杆体331和第二磁性件332，第二磁性件332固定设于第二杆体331的端面上开设的第二定位槽331a内；第一磁性件323与第二磁性件332之间具有磁吸力，当按键300处于工作状态，第一磁性件323与第二磁性件332相互贴合。第一磁性件323与第二磁性件332的贴合面均为粗糙的表面，在磁吸力的作用下，第一磁性件323与第二磁性件332之间具有足够的正压力，能够保证两个接触端面之间产生足够的摩擦力，来自按键帽310的扭矩能够被顺利传递至第二磁性件332。
可选地，第一磁性件323与第二磁性件332可以均为磁铁，并且二者保持相互吸引。
可选地，第一磁性件323与第二磁性件332中的一者为磁铁，另一者为铁或者镍等磁性金属材料。
可选地，在其他实现方式中，第一按键杆320与第二按键杆330之间还可以通过胶粘等方式以实现扭矩的顺利传递。用户通过向按键帽310施加足够的力能够将第一按键杆320与第二按键杆330从胶粘状态中分开。
图12是本申请实施例提供的智能手表的按键300的再一例的装配结构图。图13是图12所示结构的爆炸图。如图12、图13所示，相对于前述图10、图11所示的实施例，在本申请实施例中，第一磁性件323的前端从第一定位槽322c内伸出，并且沿着连接块322的端面向四周边缘延伸，从而使得第一磁性件323具有更大的接触面，该接触面不仅与第二磁性件332相贴合，还同时与第二按键杆330的端面相贴合，从而能够产生更大的摩擦力，保证扭矩被顺利传递。
进一步地，在本实施例中，第一磁性件323、第二磁性件332、第二按键杆330的端面、以及垫片440、六角螺母前端等摩擦位置均镀具有自润滑性、高硬度、高耐磨性的类金刚石薄膜(diamond-like carbon，DLC)涂层。第二按键杆330的内端面(与弹片231的接触面)、弹片231表面均镀DLC涂层，增加其旋转耐久能力，其润滑性能也能够减少按键的旋转阻尼。弹棒410的表面也镀具有自润滑性、高硬度、高耐磨性的DLC涂层，保证在第一按键杆320长期旋转的过程中不会因为弹棒410磨损而失效。
图14是本申请实施例提供的智能手表的按键300的再一例的装配结构图。图15是图14所示结构的爆炸图。
如图14、图15所示，相对于前述实施例，在本实施例中，巴管400套设于第二按键杆330的外周，第二按键杆330的外端从表面穿出至表外，并且位于巴管400内，第二按键杆330的外端面上设有卡接孔核前述的弹棒410，第一按键杆320通过弹棒410弹性卡接于该卡接孔内(可拆卸连接)。此时用户通过拉拔按键帽310即可将按 键帽310从巴管400上取下，方便用户对按键帽进行更换，用户可以个性化定制按键帽310，并能够在按键帽310上镭雕不同图形，文字等，满足用户个性换定制的需求。
以上所述，仅为本申请的具体实施方式，但本申请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申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
