Description

腕式设备及其腕带组件 技术领域
本公开涉及柔性技术领域，特别涉及一种腕式设备及其腕带组件。
背景技术
随着柔性显示技术的日趋成熟，带有柔性屏的腕表也受到市场越来越多的关注。
腕表的柔性屏通常设置于柔性腕带上，由柔性腕带带动其变形。但是，柔性屏不可能无限制地弯曲，因此，其往往对应有一个极限弯曲半径，超过该极限弯曲半径，柔性屏会因过度弯曲而损坏。
为此，市场上出现了用于控制柔性屏弯曲半径的限位机构。现有的限位机构被配置成柔性腕带的一部分并成为可见的外观部分。然而，现有的限位机构不仅防水性差，而且厚重，同时又不美观，这无疑和人们的需求背道而驰。
发明内容
鉴于此，本公开的目的在于提供一种腕式设备及其腕带组件，其中由柔性腕带包裹用于控制柔性屏弯曲半径的限位机构，以此令限位机构成为不可见的内设部件，从而提高柔性腕带的防水性，并提升腕带的美观度，还有助于将腕带设计得更为轻薄。
根据本公开的一个方面，提供一种腕带组件，包括：
一柔性腕带；以及
一限位机构，用于限制所述柔性腕带的弯曲幅度，设置于所述柔性腕带的内部并与所述柔性腕带固定。
优选的，所述限位机构与所述柔性腕带为一体成型结构。
优选的，所述限位机构整体上呈U型，所述U型的开口朝向柔性腕带的贴合手腕的表面。
优选的，所述限位机构包括：
多个第一连接件；以及
多个第二连接件，与多个所述第一连接以交替的方式顺次铰接。
优选的，任意相邻的所述第一连接件的两端和所述第二连接件的两端分别铰接。
优选的，在任意相邻的所述第一连接件和所述第二连接件中，其中一个连接件设有一限位部，另一个连接件设有一挡位部，且所述挡位部与所述限位部以可接触的方式设置，以限制该二个连接件的相对极限位置。
优选的，所述第一连接件的长度短于所述第二连接件的长度，所述第一连接件的两端分别与所述第二连接件的两端铰接。
优选的，所述第一连接件的长度方向和所述第二连接件的长度方向均垂直于所述限位机构的长度方向。
优选的，所述第一连接件的两端分别设有一个所述限位部，二个所述限位部用于与同一个所述第二连接件上的所述挡位部接触。
优选的，所述第一连接件包括本体以及与所述本体连接的二端部，每一端部的一部分结构弯折并向外侧延伸形成所述限位部；所述第二连接件的内表面构成所述挡位部，且任意一个所述限位部与所述第二连接件的所述内表面在一初始位置预留有一间隙。
优选的，所述第一连接件的两端各自设有二个所述限位部，同一端上的二个所述限位部相对设置；所述第二连接的两端各自设有二个连接部，同一端上的二个所述连接部相对设置；
所述第一连接件的每一端通过一个所述限位部与相邻的所述第二连接件之对应端上的一个所述连接部铰接。
优选的，在任意相邻的所述第一连接件和所述第二连接件中，其中一个连接件的一侧边与另一个连接件的一侧边以可接触的方式设置，以限制该二个连接件的相对转动方向。
优选的，所述柔性腕带具有一内部空间，且所述限位机构的长度小于或等于所述柔性腕带之内部空间的长度。
根据本公开的另一个方面，提供了一种腕式设备，包括所述的腕带组件，且所述腕式设备还包括：
一柔性屏，设置于所述柔性腕带上；
其中，所述限位机构设于所述柔性屏的一侧。
优选的，所述限位机构的长度大于或等于所述柔性屏的长度。
优选的，所述限位机构将所述柔性腕带的弯曲幅度限制为小于等于所述柔性屏的最大可弯曲幅度。
与现有技术相比，在本公开提供的腕式设备及其腕带组件中，通过将限位机构布置于柔性腕带的内部，使限位机构被柔性腕带包裹，以此使限位机构成为不可见的内设部件，从而使得限位机构的结构形态不会对腕式设备的外观造成任何影响，使得柔性腕带在消除其限位设计的情况下能够整体上构成腕式设备的外观件，这样便可以更为美观地设计柔性腕带，提升腕式设备的美观度。
此外，从结构上来讲，在柔性腕带的包裹下，所述限位机构的强度得到了加强，从而有助于降低限位机构自身的强度设计，使得限位机构能够被设计得更为轻薄，以此减轻腕式设备的重量，提升用户体验。另外，在消除柔性腕带之限位设计的情况下，所述柔性腕带能够被设计成具有良好防水性的外壳结构，从而提高腕式设备的防水性。

以下结合附图以及具体实施例对本公开提出的腕式设备及其腕带组件作进一步详细说明。
如在本说明书中所使用的，单数形式“一”、“一个”以及“该”包括复数对象，除非内容另外明确指出外。如在本说明书中所使用的，术语“或”通常是以包括“和/或”的含义而进行使用的，除非内容另外明确指出外。如在本说明书中所使用的，术语“外侧”通常是指远离构件之轴线方向。
图1为本公开实施例中的腕式设备的外观示意图，图2为本公开实施例中腕式设备的结构示意图，并以虚线示意图2中不可见的内设部件。如图1和图2所示，所述腕式设备包括腕带组件和柔性屏2，其中，所述腕带组件包括柔性腕带1和限位机构5，且所述柔性屏2设置于柔性腕带1上。优选，所述柔性屏2与柔性腕带1平齐设置(即柔性屏2的全部厚度均埋入于柔性腕带1之中)。
本公开中，所述柔性腕带1用于构成腕式设备的整个外壳，其可以为一体式或分体式的壳体结构，并且可以为连续的环状结构(图1所示)，也可以为断开的长条状结构(图2所示)，若为长条状结构，则该柔性腕带1的相对两端可通过卡扣的方式锁定或通过磁性吸附的方式锁定或者通过其他已知的方式锁定。继续参阅图2，所述柔性腕带1的内部设置有限位机构5，且该限位机构5与柔性腕带1固定，以便于由限位机构5来控制柔性腕带1的弯曲幅度，最终控制柔性屏2的弯曲半径。在此，本公开对限位机构5的结构不作特别的限制，只要能够起到控制柔性腕带1的弯曲幅度的作用便可。
为此，本实施例的腕式设备通过将限位机构5布置于柔性腕带1的内部，使得限位机构5被柔性腕带1包裹，以此使得限位机构5成为不可见的内设部件，从而使得限位机构5的结构形态不会对腕式设备的外观造成任何影响，使得柔性腕带1在消除其限位设计的情况下能够整体上构成腕式设备的外观件，这样便可以更为美观地设计柔性腕带1，提升腕式设备的美观度。
并且从结构上来讲，在柔性腕带1的包裹下，所述限位机构5的强度得到了加强，从而有助于降低限位机构5自身的强度设计，使得限位机构5能够被设计得更为轻薄，以此减轻腕式设备的重量，提升用户体验。另外，在消除柔 性腕带1之限位设计的情况下，所述柔性腕带1能够被设计成具有良好防水性的外壳结构，从而提高腕式设备的防水性。
本实施例中，所述柔性腕带1可由柔软的材料制成，实现可折叠，可弯曲的效果，材料可以是硅胶、橡胶、TPU等弹性材料，硬度可以是30-70HA。然而，不限于此，所述柔性腕带1还可由金属薄片制备而成，同样可达到可折叠，可弯曲的目的，金属薄片的材料可选自不锈钢。在一个非限制性的制备方法中：可预先提供一个挤压或注塑模具，之后，将限位机构5装入挤压或注塑模具中并固定，随后，往模具中加入相应的成型材料(即柔性腕带1的成型材料，不限于橡胶、硅胶、TPU)，即可使柔性腕带1成型，且成型过程中，所述限位机构5被包裹于柔性腕带1之内。具体来说，在柔性腕带1成型之前，先在模具中固定限位机构5，然后，往模具中加入液态或半固态的成型材料，从而获得内部固设有限位机构5的柔性腕带1。因此，在本实施例中，所述限位机构5与柔性腕带1优选一体成型，这样一来，无需单独组装限位机构5和柔性腕带1，可以简化整个产品的装配流程，降低生产成本。
本实施例中，所述腕式设备还可包括功能组件，该功能组件可包括电池3和电路板4。其中，所述电池3用于实现腕式设备的部分或整体供电，其可以是普通的电池(不能够被折叠，弯曲)，也可以是柔性电池(能够被折叠，弯曲)。所述电路板4为腕式设备的核心，用于构成整个腕式设备的电路结构，其与柔性屏2连接，且所述电路板4可以是普通的硬质电路板(不能够被折叠，弯曲)，或为柔性电路板(可折叠，可弯曲)。
进一步，所述电路板4可置于柔性屏2的一侧，如柔性屏2的左侧或右侧，且所述电路板4还可与电池3并排设置。更进一步，为了减小产品的厚度，所述电路板4和电池3，或其他功能组件，均优选设置于限位机构5的空隙中并与柔性腕带1固定。
所述柔性腕带1包括相对设置的正面和背面，背面用于与手腕贴合。其中，在柔性腕带1的背面上开设有一个或多个工艺孔(未图示)，以便于通过所述工艺孔将电池3和电路板4等功能组件装入柔性腕带1内。或者是，在柔性屏2放置之前，通过柔性腕带1之正面上的窗口将电池3、电路板4等功能组件预先 装入柔性腕带1内。在此，所述窗口用于放置柔性屏2，窗口的形状主要与柔性屏2的形状相匹配。
本实施例中，所述柔性屏2的下方(即背面)设置有限位机构5，所述限位机构5的长度被布置沿着柔性屏2的长度方向，且所述限位机构5的长度优选大于或等于柔性屏2的长度，如此，使得限位机构5能够在柔性屏2的安全区域限定柔性腕带1的弯曲幅度，以此同步控制该安装区域上柔性屏2的弯曲半径。
在一个推荐的方案中，所述限位机构5的长度大于柔性屏2的长度，且小于或等于柔性腕带1之内部空间的长度，这里，所述限位机构5的长度同样与柔性腕带1的长度方向一致。当所述限位机构5的长度等于柔性腕带1之内部空间的长度时，可由限位机构5限制柔性腕带1上整个区域的弯曲幅度，这样不但可保护柔性屏2，还可保护功能组件，例如避免电池3和电路板4在弯折过程中发生松动，如柔性腕带1横向弯折时FPC接头等因被拉扯而松动。本实施例中，所述限位机构5的一端可与柔性屏2的右侧对齐，另一端延伸并超过柔性屏2的左侧，并可进一步延伸至柔性腕带1的内壁处。
图3a为本公开实施例中的限位机构于未发生折叠时的整体结构示意图，图3b为图3a所示的限位机构上下翻转180°后的整体结构示意图，如图3a和图3b所示，其中的限位机构5可按箭头指示的方向向下弯曲，且弯曲的方向即是柔性腕带1佩带于手腕时的操作方向。所述限位机构5在本实施例中，整体上呈U形，且开口朝向柔性腕带1的背面(即用于贴合手腕的表面)。
图3c是图3b所示的限位机构的局部放大图，如图3c所示，所述限位机构5包括多个第一连接件51和多个第二连接件52，且多个第一连接件51和多个第二连接件52顺次交替连接，且相邻的第一连接件51和第二连接件52相互铰接，具体的，所述第一连接件51的两端分别与第二连接件52的两端铰接。并且，每个连接件均被构造成U形结构，从而使限位机构5整体上呈U形。
本实施例中，所述第一连接件51的长度短于第二连接件52的长度，且这些连接件的长度被布置为与限位机构5的长度方向相垂直，即限位机构5的横向沿着连接件的长度方向。因此，可将第一连接件51与第二连接件52的内侧 铰接，而且，也便于两者相互限位。
此外，为了控制铰接在一起的二个连接件的最大转动角度，在本实施例中，所述第一连接件51上设有一个限位部，且所述第二连接件52上设有一个档位部，且所述挡位部与所述限位部以可接触的方式设置。具体而言，在所述第一连接件51和所述第二连接件52发生相对转动的过程中，一旦所述限位部与所述挡位部相接触，则所述第一连接件51和所述第二连接件52相对静止而无法进一步转动，如此即可限定该二个连接件的最大相对转动角度，而该限位机构5与柔性腕带1固定，因此，也便限制了柔性腕带1的弯曲，进而限制了柔性屏2的弯曲半径。
本实施例中，所述第一连接件51包括本体以及与所述本体连接的二端部，且每一端部的一部分结构发生弯折并向本体外侧延伸形成一个延伸部511，该二个延伸部511均用于与同一个第二连接件52上的所述挡位部接触，从而限制该二个连接件的最大相对转动角度。因此，此处的延伸部511便构成了本实施例的限位部。较佳的，所述第二连接件52的一内表面523(即U形开口的内底面)构成所述挡位部，且在一初始位置(即第一连接件51和第二连接件52未发生相对运动时)，每个延伸部511与所述内表面523之间预留有间隙。间隙的大小直接决定了转动角度的大小，因此，可根据实际需要设定间隙值，从而控制最大相对转动角度。此处，在相邻的第一连接件51和第二连接件52未发生相对转动时，所述第一连接件51上的延伸部511即与第二连接件52的内表面523之间预留有间隙，以使得第一连接件51上的延伸部511与需要抵靠的内表面523以可接触的方式设置。
同理，为了控制第一连接件51与另一侧相邻的第二连接件52的最大转动角度，所述第一连接件51的两端各自设有二个延伸部511、512，该二个延伸部511、512相对设置并延伸方向相反，但延伸方向大致垂直于限位机构5的横向。为此，所述第一连接件51的两端分别通过一个延伸部511与一侧相邻的第二连接件52上的内表面523接触，并同时通过另一个延伸部512与另一侧相邻的第二连接件52上的内表面523接触，从而实现相互的转动限位。
进一步，所述第二连接件52的两端各自设有二个连接部521、522，且同一 端上的二个连接部521、522相对设置，以使得第二连接件52的每一端通过一个所述连接部与所述第一连接件51铰接。更进一步，所述第二连接件52上的所述连接部与所述第一连接件51上的所述延伸部相铰接。具体来说，所述第二连接件52的每一端通过一个连接部521与一侧相邻的第一连接件51上对应端上的一个所述延伸部511铰接，同时还通过另一个连接部522与另一侧相邻的第一连接件51上对应端上的一个所述延伸部512铰接。推荐的，所述连接部521、522亦可以由第二连接件52的端部之一部分结构发生弯折并向外侧延伸形成。
图3d是本公开实施例中限位机构之局部发生弯折的结构示意图，如图3d所示，在依据箭头示意的方向向上转动的过程中，一旦所述第一连接件51上的延伸部511与一侧相邻的第二连接件52上的内表面523相接触，则该二个连接件便无法进一步向上转动，以此便限定了最大相对转动角度。由于各连接件之间两两以同样的方式铰接和限位，故而任意二个相邻连接件均以如此方式限定极限位置，从而控制柔性腕带1的弯曲。
进一步，为了防止柔性腕带1发生非正常操作方向的弯折，所述限位机构5还设置有用于限制弯曲方向的功能，在一个较佳的操作中，所述第一连接件51的一侧边能够与相邻的第二连接件52的一侧边相接触，以此限定相铰接的第一连接件51和第二连接件52的转动方向，即只能按照正常的佩带方向弯曲。本实施例中，当所述第一连接件51和第二连接件52的侧边相接触时，两者的相对转动角度为零度，即未发生相对运动。更进一步，为了减小厚度，多个所述第一连接件51和多个第二连接件52对齐设置。再进一步，所述第一连接件51和第二连接件52均可以由薄片构成，薄片的厚度可控制在0.2～1.0mm的范围内，材质可选为工程塑料或碳纤维。
然而，除上述实施例外，本公开对用于限制相邻的第一连接件51和的第二连接件52的极限位置的结构不作特别的限制，只要其中一个连接件上设置有限位部，另一个连接件上设置有能够与限位部相接触的挡位部即可，另外，也不限定通过二个连接件之侧边的接触来限定限位机构的弯曲方向，因此，其他能够控制弯曲方向的结构也在本公开的保护范围之内。
最后，需要说明的是，本实施例提供的腕式设备包括但不现有腕表、手机、 电脑等，还可以是血压计、计步器等用于健康管理的电子设备。
因此，在本公开实施例提供的腕式设备及其腕带组件中，通过将限位机构5布置于柔性腕带1的内部，使得限位机构5被柔性腕带1包裹，以此使限位机构5成为不可见的内设部件，从而使得限位机构5的结构形态不会对腕式设备的外观造成任何影响，使得柔性腕带1在消除其限位设计的情况下能够整体上构成腕式设备的外观件，这样便可以更为美观地设计柔性腕带1，提升腕式设备的美观度。此外，从结构上来讲，在柔性腕带1的包裹下，所述限位机构5的强度得到了加强，从而有助于降低限位机构5自身的强度设计，使得限位机构5能够被设计得更为轻薄，以此减轻腕式设备的重量，提升用户体验。另外，在消除柔性腕带1之限位设计的情况下，所述柔性腕带1能够被设计成具有良好防水性的外壳结构，从而提高腕式设备的防水性。
上述描述仅是对本公开较佳实施例的描述，并非对本公开范围的任何限定，本公开领域的普通技术人员根据上述揭示内容做的任何变更、修饰，均属于权利要求书的保护范围。
