本发明提出一种AR眼镜腿，该结构应用于AR设备，从而能够得到质轻、外观美观、防水效果好且良好的触感的AR眼镜腿。
参照图1和图2，在本发明可选的一实施例中，AR眼镜腿1包括主体11，和亲肤层13，所述主体11包括内侧部113和外侧部115，所述外侧部115与所述内侧部113在所述主体11的径向上对接，并围合形成有至少一端开口的空腔，所述内侧部113与所述外侧部115为一体成型结构；所述装饰层15设于所述外侧部115的表面，所述亲肤层13设于所述内侧部113的表面。
可以理解的，AR眼镜腿1具有一延伸长度，能够适用于佩戴，且在横向上也具有一定的横截面。本实施例中，主体11为中空结构，可以实现轻量化，且方便部件的穿设。主体11的横截面形状可以是圆形、方形或多边形等，在此不做限定。主体11包括内侧部113和外侧部115，两者可以看做是沿主体11的纵向分割的两部分，其中内侧部113为朝向使用者的面部，外侧部115则朝向背离使用者的面部，两者在径向方向上围合形成空腔。该空腔的至少一端开口，从而方便部件或线路穿设。内侧部113和外侧部115为一体成型结构，示例性的，在两者材质为金属时，可以通过铸造或锻压一体成型，在此不做限定。
为了进一步提升该AR眼镜腿1的轻量化，可以选择主体11的材质为镁锂合金，是所有金属结构材料中密度最低的材料，可有效降低AR眼镜腿1的重量，提升佩戴体验。镁锂合金中的具体材料配比在此不做改进，故不对其进行过多阐述，只要是镁和锂元素组成的合金即可。其他示例中，主体11的材质也可以是镁铝合金或镁稀土合金等，应用场景较多，且结构强度更高，材料也为轻质材料，可以降低头戴设备的重量，提高体验感。或者，主体11的材质还可以是铝合金等，具有较低的密度，强度适中，价格便宜，应用较 为广泛。
内侧部113的表面设置有亲肤层13，该亲肤层13的材料为非金属，且导热率低于金属，从而提升其亲肤性能，避免出现低温触感。示例性的，亲肤层13的材料为高分子材料，从而质轻且结构稳定性好。例如，所述亲肤层13为丙烯酸类涂层、聚氨酯类涂层、橡胶漆类涂层或环氧树脂类涂层，具有较好的耐磨性能和防水性能，且绿色环保，不会对人体造成影响。亲肤层13的厚度范围可以根据具体主体11的尺寸进行设定，不宜过厚，否则增加材料成本，也不宜过薄，否则影响其亲肤效果，示例性的，该亲肤层13的厚度范围可以是3μm～6μm，例如，4μm、5μm等。
为了进一步提升AR眼镜腿1的外观，在外侧部115的表面镀设有装饰层15，该装饰层15的材料为金属或陶瓷，从而在AR眼镜腿1的表面可以形成两种不同质感的效果。
本发明的技术方案中，AR眼镜腿1包括主体11和亲肤层13，该主体11包括靠近使用者面部的内侧部113和背离使用者的外侧部115，两者在主体11的径向上对接围合形成一具有开口的空腔，可以实现轻量化结构，并方便进行电路或部件的设置。内侧部113和外侧部115为一体成型结构，也即可以通过一道工序加工，提高了加工效率也省去了组装工序，还可以避免主体11上出现缝隙，实现无缝一体化结构，有效提升防水性能和外观美观性。同时在内侧部113的表面设有亲肤层13，该亲肤层13可具有比金属材质低的热导率，从而能够减少使用者的冰凉感，提升该AR眼镜腿1的触感体验。
请继续参照图1和图2，可选的实施例中，装饰层15的材料为金属或陶瓷，所述装饰层15与所述亲肤层13之间形成有直线型的分界线。
金属或陶瓷材质的装饰层15能够实现更好的光泽质感，提升美观性。示例性的，该亲肤层13和装饰层15之间形成了直线型的分界线，该直线沿主体11的长度延伸方向延伸，从而在AR眼镜腿1的两侧实现不同的外观和触感，进一步提升美观。于其他示例中，该分界线也可以是曲线或不规则线条。装饰层15的厚度不宜过厚，以节约材料，当然，其厚度也不宜过薄，导致美观性不好，故可以选择3μm～6μm，例如，4μm、5μm等。
可选的实施例中，所述装饰层15的材质为光亮镍、珍珠镍、黑镍、黑铬、金、仿金、氮化钛、碳氮化钛、碳化钨、类金刚石或氮化硼。
本实施例中，为了提升更好的金属质感，选择装饰层15的材质为光亮镍、珍珠镍、黑镍、黑铬、金、仿金、氮化钛、碳氮化钛、碳化钨、类金刚石或氮化硼中的一种，光泽度好，且更加醒目。
请参照图3，本发明还提出了一种AR眼镜腿1的制备方法，该制备方法包括：
步骤S1：提供一金属管材，对其进行液压胀形成型，形成半成品，所述半成品包括沿径向分割的内侧部113和外侧部115；
步骤S2：对所述半成品进行前处理操作；
步骤S3：于所述内侧部113的表面喷涂亲肤层13；
步骤S4：于所述外侧部115的表面镀设装饰层15，形成所述AR眼镜腿1。
可以理解的，AR眼镜腿1应用于头戴设备，为了提高舒适性，该头戴设备需较轻，故为了轻量化，步骤S1中选择的金属管材的厚度不宜较大，应选择薄型管材，具体尺寸可以根据实际情况进行选择。示例性的，选择金属管 材的材质为镁锂合金，因其是所有金属结构材料中密度最低的材料，有效降低AR眼镜腿1的重量，提升佩戴体验。于其他实施例中，也可以选择镁铝合金或其他镁合金等。液压胀形工艺是液体受压时，体积不变而压力向各方向均匀传递，使材料在最有利的情况下沿模具变形，利用外侧的胀形模具控制金属管材的形状，使其完全贴附于模具内侧，得到AR眼镜腿1的半成品，也就是上述AR眼镜腿1中的主体11的外部轮廓结构，从而形成一体式无缝结构。该半成品包括内侧部113和外侧部115，此处，两者的结构参照上述实施例中的主体11的内侧部113和外侧部115，在此不做赘述。
采用液压胀形工艺加工形成的半成品具有重量轻、刚度和强度高、节约材料、结构紧凑、加工工序少等特点，能够很好地满足AR眼镜腿1轻量化的特殊要求。当然，于其他实施例中，也可以选择铸造或锻压等工艺。
步骤2中，为了方便制备，对半成品的表面进行前处理，以使其表面符合镀设的条件和状态。具体地，前处理可以是清洁或是表面结构的重设，以提高与亲肤层13之间的结合力，在此不做限定。当然，在进行表面处理之前还可以进行半成品尺寸的处理，例如，切割或打孔，以达到AR眼镜腿1所需的尺寸和结构。
步骤S3中，在内侧部113的表面喷涂亲肤层13，喷涂的方式简单易操作，成本低，可适用于批量生产。此处，亲肤层13的材质为高分子材料，其导热率低于金属，从而降低内侧部113的导热率，当AR眼镜腿1贴近使用者的面部时，可以减少冰凉感，提升使用者的触感。示例性的，亲肤层13为丙烯酸类涂层、聚氨酯类涂层、橡胶漆类涂层或环氧树脂类涂层，具有良好的耐磨性能和防水性能，且绿色环保，不会对人体造成影响。该亲肤层13的 喷涂厚度可以根据实际情况进行设定，保证内侧部113的表面均覆盖亲肤层13即可。
在内侧部113喷涂有亲肤层13后，步骤S4中，进行装饰层15的镀设。此处，镀设工艺也可以是电镀或是磁控溅射，或是其他常规镀设工艺，加工成本低。且上述镀设工艺均为常用镀设工艺，具体的镀设过程在此不做过多赘述。示例性的，装饰层15的材质为金属，从而实现较好的金属光泽质感。例如，装饰层15的材质为光亮镍、珍珠镍、黑镍、黑铬、金、仿金、氮化钛、碳氮化钛、碳化钨、类金刚石或氮化硼。镀设的装饰层15的厚度可以根据需要进行设定，例如为3μm～6μm，节约材料且质感较好。如此，则可以完成对AR眼镜腿1的制备。
本发明的制备方式工艺简单，工艺流程高效，成本低适用于工业化大批量生产。同时，制备得到的AR眼镜腿1为无缝一体式结构，且在内外侧具有双质感设计，提升其外观的同时能够使得使用者的触感良好。
可选的实施例中，所述前处理操作包括机械处理和/或化学处理，其中，机械处理包括打磨抛光、擦拭和水洗中的至少一种，所述化学处理包括化学脱脂、化学碱洗、化学酸洗和活化中的至少一种。
可以理解的，在半成品通过液压胀形/压铸或其他工序制成时，表面通常会残留有一些油渍或油污，故本实施例中，前处理操作可以包括机械处理和/或化学处理，从而对机械进行除油处理。例如，机械处理包括打磨抛光、擦拭、使用清水对其进行清洗中的至少一种，以除去表面的油污和杂质；也可以使用化学处理，例如化学脱脂、或者使用碱性物质进行碱洗。或者可以同时使用机械处理和化学处理。为了进一步提高半成品的表面活性，还可以对 其进行活化处理。该活化处理可以选择稀硫酸或醋酸进行化学酸洗，或使用活性物质进行活化清洗，稀硫酸的浓度范围为1～3mol/L，且活化时间为30s左右，可以得到新鲜的半成品表面，并防止对管材基底产生结构影响。当然，还可以通过电解活化方式进行活化处理，在此不做限定。示例性的，进行上述化学处理后，可以选择使用清水或去离子水进行彻底清洗，以将进行活化残留的试剂去除，提高其表面结合能力。
当然，于其他实施例中，也可以只选择除油处理、活化处理以及再次清洗中的一者。
请结合图4，可选的实施例中，于所述内侧部113的表面喷涂亲肤层13的具体步骤包括：
步骤S31：对所述半成品进行整体喷涂所述亲肤层13；
步骤S32：对所述外侧部115进行激光镭雕，去除所述外侧部115的亲肤层13。
本实施例中，为了形成内侧部113的亲肤层13，首先通过步骤S31对整个半成品进行喷涂亲肤层13，从而可以简化该操作过程，提升喷涂效率。然后再通过激光镭雕的方式将外侧部115的亲肤层13去除掉，以此只保留内侧部113的亲肤层13。该工艺可以通过激光镭雕的精度去实现亲肤层13与装饰层15之间的清晰的分界线，从而实现两者质感的区分，进一步保证美观性。
于其他示例中，也可以通过遮挡外侧部115，仅在内侧部113喷涂亲肤层13。
请结合图5，可选的实施例中，对所述半成品进行前处理操作的步骤之后，对所述半成品进行整体喷涂所述亲肤层13的步骤之前，还包括步骤：
步骤S25：对所述半成品的整体表面镀设保护层。
本实施例中，因需要进行激光镭雕，为了防止对半成品的内部结构产生影响，在完成前处理操作，并进行整体喷涂亲肤层13之前，在半成品的表面整体镀设一层保护层，该保护层用于实现对半成品的表面进行防护，在激光去除亲肤层13时，可以承受激光照射同时不发生力学性能和化学性质的显著改变，提升AR眼镜腿1的内部结构强度。此处，保护层的镀设方式可以是电镀，从而同时实现与亲肤层和装饰层较好的结合强度，同时具有耐腐蚀性能，其他示例中，也可是其他镀膜工艺，在此不做限定。
可选的实施例中，所述保护层的材质为锌、铜或半光亮镍。
本实施例中，保护层的材质强度应该相对较高，例如，锌、铜或半光亮镍等，从而具有一定强度的基础上，具有较好的防腐蚀性能，进而提高对半成品的性能保护。
可选的实施例中，对所述外侧部115进行激光镭雕，去除所述外侧部115的亲肤层13的步骤具体为：
步骤S321：遮挡所述内侧部113，对所述半成品进行激光镭雕，以去除所述外侧部115的亲肤层13。
本实施例中，为了对亲肤层13进行防护，在进行激光镭雕时，可以设置遮挡结构，能够遮挡内侧部113的位置，从而提升激光镭雕的效率，并保证该AR眼镜腿1的制备方法的成品率，有效降低成本。该遮挡结构不限定，保证能够阻挡激光穿设即可。且该遮挡结构可以为平面，放于内侧部113和外侧部115之间的位置即可，或者也可以与内侧部113的形状相匹配，从而实现完全的遮盖。
本发明还提出了一种AR设备，所述AR设备包括主体11和与所述主体11连接的两个AR眼镜腿1，所述AR眼镜腿1为如上任一所述的AR眼镜腿1，或所述AR眼镜腿1采用如上任一所述的AR眼镜腿1的制备方法制备。由于AR设备壳体采用了前述所有实施例的全部技术方案，因此至少具有前述实施例的技术方案所带来的有益效果，在此不再一一赘述。
示例性的，AR设备可以是AR眼镜或AR头盔等。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
