具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在无需做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另作定义，本文使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其它元件或者物件。“上”、“下”“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本发明。
如图1和图2所示，本公开提供一种佩戴式电子设备，所述佩戴式电子设备包括显示部100和与该显示部100相连的固定部200。该固定部200用于将所述佩戴式电子设备固定在佩戴者身上，显示部100包括显示屏110。固定部200上设置有热电转换模块300，该热电转换模块300与外界绝缘隔离，并且该热电转换模块300能够将佩戴者的人体与外部环境之间的温差转 换为供所述佩戴式电子设备运行的电能。
热电转换模块300与外界绝缘隔离设置，可以防止热电转换模块300在工作的时候发生漏电。
由于佩戴者的人体与外部环境之间存在温差，热电转换模块300可产生电能，该电能用于驱动显示部100进行显示。因此，在使用本公开所提供的佩戴式电子设备时，无需利用外部电源对其进行充电，从而可以提高佩戴式电子设备的续航能力。
当佩戴者佩戴所述佩戴式电子设备时，固定部的一侧表面与人体接触，另一侧表面暴露在环境中，此处的“温差”是因佩戴者的体温和环境温度之间的温差产生的，热电转换模块300可以充分利用环境温度，从而可以降低佩戴式电子设备的使用成本，并且可以节约能源。
为了充分利用热电转换模块300所产生的电能，例如，显示部100还可以包括蓄电池120。该蓄电池120的输入端与热电转换模块300的输出端相连，以存储热电转换模块300产生的电能，蓄电池120的输出端与显示屏110的电源输入端相连。
蓄电池120可以将电能转换为化学能，从而可以将热电转换模块300产生的电能进行存储。
当然，所述佩戴式电子设备也可以不包括蓄电池，而是包括整流装置。该整流装置能够将热电转换模块产生的电流转换为供显示部运行的稳定电流。
为了提高发电量，例如，热电转换模块300可以包括多个热电转换子模块310。例如，该多个热电转换子模块310互相串联。所有热电转换子模块310利用自身温差产生的电能均能够输送至蓄电池120中进行存储。
作为本公开的一种实施方式，多个热电转换子模块310中的一部分以佩戴者的人体为热源，以该热电转换子模块310所处的外部环境为冷源，其余热电转换子模块310以该热电转换子模块310所处的外部环境为热源，以佩戴者的人体为冷源。当人体温度高于外部环境温度时，以佩戴者的人体为热源，以外部环境为冷源的热电转换子模块310产生电能；当人体温度低于外部环境温度时，以佩戴者的人体为冷源、以外部环境为热源的热电转换子模块310产生电能。如图2所示，虚线框所示的热电转换子模块310以佩戴者的人体为热源，实线框所示的热电转换子模块310以外部环境为热源。这种 设置确保任何温度下均能产生电能。
在图2中，以人体为热源的热电转换子模块310和以外部环境为热源的热电转换子模块是交替设置的，但是，本发明并不限于此。
此处，先不对各个热电转换子模块的设置方式进行描述，下文中将结合示例的实施方式对其进行描述。
为了确保以外部环境为热源的热电转换子模块310能够充分利用外部环境中的热量，例如，以外部环境为热源的所述热电转换子模块的朝向环境一侧的表面上设置有吸热材料层214(如图6所示)。或者，可以在以人体为热源的热电转换子模块上用于与人体贴合的表面上设置所述吸热材料层。还可以在以外部环境为热源的热电转换子模块以及以人体为热源的热电转换子模块上都设置吸热材料层。吸热材料层具有良好的导热性，从而可以更好的吸收热量。吸热材料层的比热小于制成固定部的材料的比热。作为本公开的一种实施方式，吸热材料层214的材料可以是电镀金属涂层。
在本公开中，佩戴式电子设备例如可以是智能手表，但是本发明并不限于此。如图1所示，显示部100既可以具有通信功能，又具有显示时间的功能。在一种情况中，如图1所示，显示部100和固定部200可以形成封闭的环形，从而可以将佩戴式电子设备固定在佩戴者的手腕上。
在本公开中，固定部200的形状形成为使其能够承载热电转换模块300、并且能够与显示部100形成封闭的环状。在本公开中，例如，固定部200可以形成为链状。在这种实施方式中，所述固定部200包括多个固定块210，相邻的固定块210互相铰接，相应地，每个固定块210上可以设置一个热电转换子模块310。
在本公开中，例如，可以在固定块210中设置空腔，然后将热电转换子模块310设置在该空腔中，但是本发明并不限于此。多个热电转换子模块310串联后，各个热电转换子模块310产生的电能均能够输送至蓄电池120中。
作为本公开的一种实施方式，如图3所示，热电转换子模块310可以包括至少一个热电转换单元310a。热电转换单元310a包括P型半导体311、N型半导体312、第一电极板313和两个第二电极板314。第一电极板313位于热电转换单元310a的一侧，P型半导体311和N型半导体312均固定在第一电极板313上。P型半导体311远离第一电极板313的一端设置有一个第二电极板314，N型半导体312远离第一电极板313的一端设置有另一个第二 电极板314。P型半导体311和N型半导体312均为热电材料。P型半导体311和N型半导体312的赛贝克(Seeback)系数不同。
根据赛贝克效应，不同的金属导体(或半导体)具有不同的自由电子密度(或载流子密度)，当两种不同的金属导体(或半导体)接触时，接触面上的电子(或载流子)就会由高浓度向低浓度扩散。而电子(或载流子)的扩散速率与接触区的温度层正比，只要维持两种金属导体(或半导体)件的温差，就能使电子持续扩散，并在两个金属导体(或半导体)的互相不接触的两个端形成稳定的电压。
在本公开中，P型半导体311的一端和N型半导体312的一端通过第一电极板313相接触，另一端分别与两个不同的第二电极板314相接触，由于P型半导体311和N型半导体312的赛贝克系数不同，因此，当第一电极板313与第二电极板314之间存在温差时，热电转换单元310a中就会有电流产生，在与P型半导体311相连的第二电极板314以及与N型半导体312相连的第二电极板314之间形成电动差，其中，与P型半导体311相连的第二电极板314形成为正极，与N型半导体312相连的第二电极板314形成为负极。
在热电转换单元310a中，通常是第一电极板313与热源邻接，而第二电极板314与冷源邻接，从而使得第一电极板313和第二电极板314之间形成温差，进而产生电流。
为了使得热电转换模块300与外界绝缘隔离，在本公开中，第一电极板313及第二电极板314应当与外界绝缘隔离。
为了便于收集热量，例如，固定块210可以包括绝缘的第一导热板211和绝缘的第二导热板212。如图4和图6中所示，第一电极板313固定在第一导热板211上，第二电极板314固定在第二导热板212上。
为了避免导热板受到损伤，例如，所述固定块包括导热保护层213。可以在第一导热板211背离第二导热板212的表面(即，图4和图6中的上表面)上设置导热保护层213，也可以在第二导热板212背离第一导热板211的表面(即，图4和图6中的下表面)上设置导热保护层213。当然，可以在第一导热板和第二导热板的一者上设置导热保护层，也可以在二者上都设置导热保护层。顾名思义，导热保护层213不仅可以导热，而且可以保护设置该导热保护层的第一导热板或第二导热板免受损伤。
如图5所示，在本公开中，例如，固定块210可以包括第一导热板211、 设置在第一导热板211上的导热保护层213、第二导热板212、设置在第二导热板上的导热保护层213。
如上文中所述，相邻两个固定块可以互相铰接，以形成链状的固定部，使得固定部的表面更容易与佩戴者的手腕相接触，更容易吸收人体的热量。为了实现固定块的铰接，例如，相邻两个所述固定块中，设置在所述第一导热板上的所述导热保护层互相铰接，和/或，相邻两个所述固定块中，设置在所述第二导热板上的所述导热保护层互相铰接。
在图5所示的实施方式中，每个导热保护层213上都设置了用于铰接的结构。例如，导热保护层213的一端(图5中的左端)设置了铰接凸起部213a，铰接凸起部上设置有第一铰接孔213b，导热保护层的另一端(图5中的右端)设置有第二铰接孔213c。在铰接时，一个固定块中的导热保护层的铰接凸起部213a中的第一铰接孔213b与相邻的固定块中的导热保护层的第二铰接孔对齐，然后在对齐的第一铰接孔和第二铰接孔中设置枢转轴，从而可以将相邻的两个固定块铰接在一起。
在佩戴所述佩戴式电子设备时，第二导热板212与佩戴者的手腕相贴合，从而将人体的体温传导至热电转换单元310的P型半导体311和N型半导体312的一侧，第一导热板211暴露于空气中，从而将环境温度传导至热电转换单元310a的P型半导体311和N型半导体312的另一侧。由于热电转换单元310a的一侧与热电转换单元310a的另一侧之间存在温差，因此，热电转换单元310a能够产生电能，并将产生的电能输送至蓄电池120中进行存储，以驱动显示屏110进行显示。
在本公开中，P型半导体和N型半导体的材料为热电材料，例如那些工作温度范围在25℃～100℃之间的热电材料。作为本公开的一种实施方式，P型半导体311包括P掺杂的Bi2Te3，N型半导体312包括N掺杂的Bi2Te3。
例如，P型半导体311中的掺杂元素为Sb，N型半导体312中的掺杂元素为Se。
在本公开中，第一导热板211以及第二导热板212的材料可以为具有良好的导热性并且可以绝缘的材料。例如，第一导热板211或者第二导热板212可以为陶瓷材料，或者第一导热板211和第二导热板212均由陶瓷材料制成。例如，所述陶瓷材料可以为Al2O3陶瓷。
如图4和6中所示，在同一个所述固定块上可以包括多个所述热电转换 单元。如图4和6中所示，为了便于制造，例如，一个热电转换单元310a的N型半导体与另一个热电转换单元310a的P型半导体相邻，一个热电转换单元310a的第二电极板与另一个转换子模块310a的第二电极板形成为一体，从而将一个固定块上的多个热电转换单元310a串联在一起。
为了便于连接，例如，热电转换子模块可以包括引出端和引入端，所述引出端与所述热电转换模块的一个端部的热电转换单元的P型半导体的第二电极相连，所述引入端与所述热电转换模块的另一个端部的热电转换单元的N型半导体的第二电极相连，电流从所述引入端流入所述热电转换子模块，电流从所述引出端流出。
如上文中所述，在一个热电转换单元中，包括两个第二电极和一个第一电极。如图4中所示，在热电转换子模块310的最左端的热电转换单元310a中，P型半导体的上端设置的电极板与该P型半导体左侧的N型半导体共用，而P型半导体下端的电极板是一个独立的电极板，因此，该独立的电极板为热电转换子模块310的最左端的热电转换单元310a的第二电极板。在一个热电转换单元中，与第二电极板相邻的是冷源。可以看出，在图4中所示佩戴式电子设备中，下表面是用于与人体接触的，也就是说，在图4中所示的佩戴式电子设备中，是以外部环境为热源、以人体为冷源的。
当然，本发明并不限于此。例如，在图6中所示的实施方式中，左侧的固定部是以人体为冷源、以外部环境为热源的，而右侧的固定部则是以人体为热源、以外部环境为冷源的。
例如，各个固定块中的热电转换子模块的设置方式可以包括以下几种情况：
第一种情况是：在所述固定部中，在相邻两个所述固定块中，一个所述固定块中的热电转换子模块的引出端对应的第二电极设置在所述第一导热板和所述第二导热板中用于与人体接触的一者上，另一个所述固定块中的热电转换子模块的引入端对应的第二电极设置在所述第一导热板和所述第二导热板中用于与外部环境接触的一者上。这种实施方式可以实现以外部环境为热源的热电转换子模块和以人体为热源的热电转换子模块交替设置。
第二种情况为：在所述固定部中，所有的所述热电转换子模块的引出端对应的第二电极均设置在所述第一导热板和所述第二导热板中用于与人体接触的一者上。相应地，所有的所述热电转换子模块的引入端对应的第二电极 均设置在所述第一导热板和所述第二导热板中用于与人体接触的一者上。这种情况便是图4中所示的情况，所有的热电转换子模块均以人体为冷源，以外部环境为热源。
第三种情况为：所有的所述热电转换子模块的引出端对应的第二电极均设置在所述第一导热板和所述第二导热板中用于与外部环境接触的一者上。相应地，所有的所述热电转换子模块的引入端对应的第二电极也均设置在所述第一导热板和所述第二导热板中用于与外部环境接触的一者上。这种情况是，所有的热电转换子模块均以人体为热源、以外部环境为冷源。
第四种情况为：所述固定部被划分为两部分，一部分所述固定部中热电转换子模块的引入端对应的第二电极与所述第一导热板和所述第二导热板中用于与人体接触的一者上，相应地，一部分所述固定部中热电转换子模块的引出端对应的第二电极与所述第一导热板和所述第二导热板中用于与人体接触的一者上。另一部分所述固定部中的热电转换子模块的引入端对应的第二电极与所述第一导热板和所述第二导热板中用于与外部环境接触的一者上，相应地，另一部分所述固定部中的热电转换子模块的引出端对应的第二电极与所述第一导热板和所述第二导热板中用于与外部环境接触的一者上。这种情况为，一部分热电转化子模块以人体为热源、以外部环境为冷源，另一部分热电转换子模块以外部环境为热源、以人体为冷源。这种情况是图5和图6中所示的情况。
为了便于将热电转换模块产生的电能输送至蓄电池中，例如，如图7中所示，热电转换模块的输出端包括与位于所述固定部的与显示部相连的端部的P型半导体相连的正极端子400和与位于所述固定部的与显示部相连的端部的所述N型半导体相连的负极端子500。热电转换模块的正极端子与蓄电池的正极相连，热电转换模块的负极端子与蓄电池的负极相连。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
