Description

连接器以及灯具系统 技术领域
本发明涉及照明技术领域，尤其涉及一种连接器以及灯具系统。
背景技术
随着照明行业技术的发展，照明技术工艺得到了极大的突破，其中，线性照明方案日趋成熟。线性照明即是以简约线条灯为依托，通过成形多种直线、圆形或不规则曲线来阐述对空间的创意设计，安装过程中需要在灯具之间进行角度转向连接，并且要保持灯光效果的连续性、延展性与均匀性，才能够用灯光来勾勒场景线条，构建出各种时尚简约造型和光影效果。
目前，线性照明灯具的连接技术难以匹配各种新颖的线性照明方案，在灯具造型布局安装过程中，灯具间的转向连接器存在转向变化单一、转向不连贯及结构复杂的问题。
发明内容
本发明公开一种连接器以及灯具系统，以解决目前的灯具间的转向连接器存在转向变化单一、转向不连贯及结构复杂的问题。
为了解决上述问题，本发明采用下述技术方案：
一种连接器，包括第一转向单元、第二转向单元和中心转轴，所述第一转向单元和所述第二转向单元均与所述中心转轴连接、且均在所述中心转轴的轴向上被限位；所述第一转向单元和所述第二转向单元中至少有一者可转动配合于所述中心转轴、且转动轴线与所述中心转轴的轴线共线。
所述第一转向单元和所述第二转向单元均转动连接有转向连接件，所述转向连接件的转动轴线与所述中心转轴的轴线相交，所述转向连接件用于装配灯具。
一种灯具系统，包括上文所述的连接器，以及通过所述连接器装配的至 少两个灯具。
本发明采用的技术方案能够达到以下有益效果：
本发明实施例公开的连接器中，第一转向单元和第二转向单元中至少有一者可转动配合于中心转轴，所以第一转向单元和第二转向单元能够实现相对转动；在第一转向单元和第二转向单元上转动连接有转向连接件，且转向连接件的转动轴线与中心转轴的轴线相交，与转向连接件相连的灯具既可以围绕转向连接件的转动轴线实现转动操作，又可以间接通过第一转向单元和第二转向单元实现围绕中心转轴的转动操作，进而能够达到在两个维度平面的自由转动。
相较于现有的转向连接器存在转向变化单一、转向不连贯及结构复杂的问题而言，本发明实施例公开的连接器无疑具备转向多样化、转向过渡平滑的优势，同时结构简单，转向操作便捷。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有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。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
请参考图1-图7，本发明实施例公开一种连接器，包括第一转向单元100、第二转向单元200和中心转轴300，第一转向单元100和第二转向单元200均与中心转轴300连接。中心转轴300是连接器的转动基础构件，能够为第一转向单元100和第二转向单元200提供了安装基础。
同时，第一转向单元100和第二转向单元200均在中心转轴300的轴向上被限位。灯具往往都是易碎物品，如果第一转向单元100和第二转向单元200在中心转轴300上能够相对移动，则连接器所连接的灯具容易出现位移，灯具与灯具之间、灯具与周围的物体之间的磕碰的概率会大大增加，极易造成灯具的损坏。基于此，本发明实施例所公开的连接器，对第一转向单元100和第二转向单元200在中心转轴300的轴向上都进行了限位，当然，具体的 限位方式可以有多种，例如中心转轴300的两端可以有阻挡结构进行限位，或者可以通过紧固件(螺母、铆钉等)将第一转向单元100和第二转向单元200分别固定于中心转轴的两端，本发明实施例对其不做限制。
第一转向单元100和第二转向单元200中至少有一者可转动配合于中心转轴300。具体的，即是指第一转向单元100和第二转向单元200可以都转动配合于中心转轴300，或者第一转向单元100和第二转向单元200中的其中任一者转动配合于中心转轴300，而另一者固定配合于中心转轴300，同时可以明确的是，第一转向单元100和第二转向单元200能够相对转动。本发明实施例对第一转向单元100和第二转向单元200分别与中心转轴300的具体配合关系不做限制。在具体的使用过程中，当第一转向单元100和第二转向单元200通过后文所述的转向连接件400与灯具连接时，因此灯具也能够围绕中心转轴300进行转动操作。
通常情况下，第一转向单元100和/或第二转向单元200的转动轴线与中心转轴300的轴线共线，此时，第一转向单元100和/或第二转向单元200的转动动作无疑流畅度最高，转动效率也最佳，否则第一转向单元100和/或第二转向单元200在转动时可能会与中心转轴300发生干涉，特别是在第一转向单元100和第二转向单元200通过转向连接件400连接有灯具时，由于整个灯具系统尺寸的增加，在转动灯具时发生磕碰的概率会提升，进而灯具被损坏的概率上升；当然，本发明实施例对第一转向单元100和/或第二转向单元200与中心转轴300的具体转动配合关系不做限制。
如前文所述，第一转向单元100和第二转向单元200均转动连接有转向连接件400，转向连接件400的转动轴线与中心转轴300的轴线相交，转向连接件400用于装配灯具。具体的，基于前述的第一转向单元100和第二转向单元200中至少有一者可转动配合于中心转轴300，本发明实施例公开的连接器能够实现第一个维度平面内灯具的转动，再结合转向连接件400转动连接于第一转向单元100和第二转向单元200，且灯具通过转向连接件400 间接连接于第一转向单元100和第二转向单元200，则本发明实施例公开的连接器能够实现第二个维度平面内灯具的转动。
本发明实施例公开的连接器实现了两个维度平面内的灯具的转动，这两个维度平面的选择是基于转向连接件400的转动轴线与中心转轴300的轴线的角度关系，通常情况下，转向连接件400的转动轴线与中心转轴300的轴线相垂直，此时灯具之间都处于平行的不同平面内，能够有效避免灯具之间发生干涉磕碰，安全性较佳；当然，转向连接件400的转动轴线与中心转轴300的轴线可以呈锐角，例如60°、30°等，此时需要考虑灯具的长度以及不同转向连接件400的角度设计，以避免灯具之间出现干涉磕碰，设计、加工难度较高，成本提高，但也同时具有灯具造型布局多样性的优势。在本发明实施例中，不限制转向连接件400的转动轴线与中心轴线300的轴线的具体角度关系。
由上述内容可知，本发明实施例公开的连接器中，第一转向单元100和第二转向单元200中至少有一者可转动配合于中心转轴300，所以第一转向单元100和第二转向单元200能够实现相对转动；在第一转向单元100和第二转向单元200上转动连接有转向连接件400，且转向连接件400的转动轴线与中心转轴300的轴线相交，与转向连接件400相连的灯具既可以围绕转向连接件400的转动轴线实现转动操作，又可以间接通过第一转向单元100和第二转向单元200实现围绕中心转轴的转动操作，进而能够达到在两个维度平面的自由转动。
相较于现有的转向连接器存在转向变化单一、转向不连贯及结构复杂的问题而言，本发明实施例公开的连接器无疑具备转向多样化、转向过渡平滑的优势，同时结构简单，转向操作便捷。
通常情况下，第一转向单元100能够可转动配合于中心转轴300，第二转向单元200可以与中心转轴300固定配合。具体的，第一转向单元100能够相对于中心转轴300转动，则中心转轴300也可以相对于第一转向单元100 转动，在这种情况下，与中心转轴300固定配合的第二转向单元200就也可以相对于第一转向单元100转动，进而第一转向单元100和第二转向单元200都可以实现围绕中心转轴300的轴线转动动作。相较于第一转向单元100和第二转向单元200中有一者与中心转轴300固定配合的实施方式，第一转向单元100和第二转向单元200都与中心转轴300可转动配合的实施方式，对灯具的调节会更具灵活性，但稳定性较差。
请再次参考图2-图5，在本发明实施例中，第一转向单元100和第二转向单元200与中心转轴300的配合关系有多种，例如第一转向单元100和第二转向单元200可以通过中间连接件与中心转轴300实现配合。第一转向单元100可以具有第一安装孔110，第一转向单元100通过第一安装孔110套接在中心转轴300上、且第一转向单元100和中心转轴300之间具有转动间隙。具体的，第一转向单元100套接在中心转轴300上，其一使得第一转向单元100与中心转轴300的连接稳定性更高，不容易被损坏；其二避免了使用其他的中间连接件，使得本发明实施例公开的连接器的结构更加简单精巧。第一转向单元100和中心转轴300之间具有转动间隙，确保了第一转向单元100和中心转轴300之间的转动流畅性，避免了二者发生干涉。
第二转向单元200可以具有第二安装孔210，中心转轴300在第二安装孔210与第二转向单元200螺纹配合。具体的，中心转轴300上可以具有外螺纹，而第二安装孔210内可以具有内螺纹，则中心转轴300与第二转向单元200螺纹配合实现固定连接。当然，在本发明实施例中，中心转轴300与第二转向单元200的固定配合关系可以有多种，例如第二转向单元200还可以一体成型于中心转轴300。
在一种具体的实施方式中，中心转轴300可以为自攻螺钉。在具体的装配过程中，自攻螺钉通过第一安装孔110和第二安装孔210，依次穿入第一转向单元100和第二转向单元200，由于自动螺钉与第一转向单元100之间具有转动间隙，所以第一转向单元100可以围绕自攻螺钉转动、且不会被干 涉；然后，将自攻螺钉攻入到第二安装孔210中，即实现自攻螺钉与第二转向单元200的固定配合，实现对第二转向单元200的限位；同时，由于自攻螺钉具有螺帽，第一转向单元100在螺帽处被阻挡，实现对第一转向单元100的限位；通过调节控制自攻螺钉扭力，可以调整对第一转向单元的阻尼大小，进而控制第一转向单元100的转动顺畅度。当第一转向单元100的角度位置确定之后，可以旋紧自攻螺钉，进而固定第一转向单元100和第二转向单元200的位置关系。
为了提升第一转向单元100和第二转向单元200的转动稳定性，请再次参考图3和图4，在更为优选的方案中，第一转向单元100可以具有第一套管120，第一套管120的轴线与第一安装孔110的轴线共线，第二转向单元200可以具有第二套管220，第二套管220的轴线与第二安装孔210的轴线共线；第一套管120和第二套管220均呈圆筒状、且二者的内径均大于中心转轴300的外径，第一套管120套接配合于第二套管220、且二者之间为间隙配合。具体的，当第一转向单元100和第二转向单元200之间发生相对转动时，第一套管120和第二套管220之间也随之发生相对转动，由于第一套管120和第二套管220均具有一定的长度，二者相互之间贴合的面积较大，因此转动稳定性更佳。
在一种具体的实施方式中，第二套管220可以套接配合于第一套管120的外侧。在这种情况下，第二套管220的内径大于第一套管120的外径。当然，本发明实施例对第一套管120和第二套管220的具体套接配合关系不做限制，例如第一套管120也可以套接配合于第二套管220的外侧。
由于第一转向单元100与第二转向单元200的转动范围为360°，灵活性有余而稳定性不足，当连接器连接有灯具时，灯具进行360°无约束转动则会存在潜在的安全风险。基于此，在更为优选的方案中，第一转向单元100的外壁可以设置有第一定位凸部130，第二转向单元200的外壁可以设置有第二定位凸部230，第二定位凸部230能够在第二转向单元200的转动方向 上限制第一定位凸部130的转动。在本发明实施例中，第一定位凸部130和第二定位凸部230的形状可以有多种，例如第一定位凸部130和第二定位凸部230可以为挡块、定位凸起等，本发明实施例对其不做限制，只要第一定位凸部130和第二定位凸部230能够互相接触进行限位即可。
当第一转向单元100和第二转向单元200相互之间受到的转动作用力过大时，第一定位凸部130和第二定位凸部230在接触时，其中一者可能会被推送至另一者上方，进而对连接器造成损坏。基于此，在更为优选的方案中，第一定位凸部130的两侧可以设置有第一斜面131，第二定位凸部230的两侧可以设置有第二斜面231，当第一定位凸部130被第二定位凸部230限制转动时，第一斜面131与第二斜面231贴合。在这种情况下，由于第一斜面131和第二斜面231的相互受力面积较大，第一定位凸部130和第二定位凸部230不会造成相互损伤，且第一定位凸部130被第二定位凸部230的连接稳定性更佳，进而进一步强化了了第一转向单元100和第二转向单元200的连接稳定性。
在本发明实施例中，第一斜面131和第二斜面231的设置形式可以有多种，本发明实施例对其不做限制。在一种具体的一种实施方式中，第一斜面131与第一定位凸部130上的相邻面的夹角可以为45°，第二斜面231与第二定位凸部230上的相邻面的夹角为45°，此时第一斜面131和第二斜面231在接触时可以完全贴合。当然，第一斜面131与第一定位凸部130上的相邻面的夹角还可以为30°或者60°等，第二斜面231与第二定位凸部230上的相邻面的夹角还可以为60°或者30°等，只需要第一斜面131和第二斜面231能够完全贴合即可。
请再次参考图5和图6，转向连接件400与第一转向单元100(第二转向单元200)的转动配合关系可以有多种，本发明实施例对其不做限制。在具体的一种实施方式中，第一定位凸部130(第二定位凸部230)上可以设置有连接转轴140(连接转轴240)，转向连接件400转动配合于连接转轴140(连 接转轴240)、且在连接转轴140(连接转轴240)的轴向上被限位。具体的，转动连接件400可以套接在连接转轴140(连接转轴240)上，以形成转动配合，同时，转动连接件400在连接转轴140(连接转轴240)的轴向上被限位，以避免转动连接件400分别在连接转轴140(连接转轴240)上出现位移，确保转动连接件400的连接稳定性。
当然，本发明实施例对连接转轴140(连接转轴240)的设置位置不做限制，例如连接转轴140(连接转轴240)可以设置在第一转向单元100(第二转向单元200)的本体上，而不用设置在第一定位凸部130(第二定位凸部230)，但这种设置方式会对第一转向单元100(第二转向单元200)的转动造成干涉，减小它们的转动范围。转向连接件400与第一转向单元100(第二转向单元200)的转动配合关系还可以为其他，例如转向连接件400上可以设置有转轴、且转轴与第一转向单元100(第二转向单元200)转动连接；还可以通过滚动轴承来实现转向连接件400与第一转向单元100(第二转向单元200)的转动配合。
与此同时，转向连接件400的转动轴线与连接转轴140(连接转轴240)的轴线共线。在这种情况下，转向连接件400的转动动作无疑流畅度最高，转动效率最佳；当转向连接件400连接有灯具时，由于整个灯具系统尺寸的增加，在转动灯具时发生磕碰的概率会提升，进而灯具被损坏的概率上升；当然，本发明实施例对转向连接件400与连接转轴140(连接转轴240)的具体转动配合关系不做限制。
在一种具体的实施方式中，两个转向连接件400在靠近第一转向单元100(第二转向单元200)的一端可以设置有第一卡槽410，第一卡槽410呈U型，连接转轴140(连接转轴240)转动配合于第一卡槽410，第一卡槽410的开口两侧具有限位凸起411，限位凸起411限位配合于连接转轴140(连接转轴240)。在具体的装配过程中，连接转轴140(连接转轴240)通过第一卡槽410的开口进入到第一卡槽410中，并能够在第一卡槽410中进行转动 动作，由于第一卡槽410的开口两侧设置有限位凸起411，限位凸起411对连接转轴140(连接转轴240)进行限位，防止连接转轴140(连接转轴240)从第一卡槽410中脱出。当然，转向连接件400与第一转向单元100(第二转向单元200)的转动配合关系还可以为其他，例如第一卡槽410可以设置在第一转向单元100(和第二转向单元200)上，其他结构适应性改变设置。
在更为优选的方案中，连接转轴140(连接转轴240)在与转向连接件400配合的一端设置有阻挡部141(阻挡部241)，转向连接件400具有容纳阻挡部141(阻挡部241)的避让空间430，当连接转轴140(连接转轴240)转动配合于第一卡槽410时，阻挡部141(阻挡部241)在连接转轴140(连接转轴240)的轴向上对转向连接件400进行限位。具体的，阻挡部141(阻挡部241)的周向尺寸需要大于第一卡槽410的尺寸，以确保阻挡部141(阻挡部241)不能通过第一卡槽410，如此就可以在连接转轴140(连接转轴240)的轴向上对转向连接件400进行限位。避让空间430能够容纳阻挡部141(阻挡部241)，避免转向连接件400与连接转轴140(连接转轴240)发生干涉。除此之外，对转向连接件400的限位方式还可以为其他，例如可以在连接转轴140(连接转轴240)上装配紧固件(螺母、铆钉等)来对转向连接件400进行限位。
为了便于与灯具之间的装配和拆卸，在更为优选的方案中，转向连接件400在背离第一转向单元100或第二转向单元200的一端可以设置有连接部420，转向连接件400通过连接部420装配于灯具。在本发明实施例中，连接部420的结构类型可以有多种，例如连接部420可以为螺柱，而灯具上开设有螺纹孔，进而连接部420可以与灯具螺纹配合。本发明实施例对连接部420的具体结构类型不做限制。
在一种具体地实施方式中，连接部420可以包括相对设置的第一卡爪421和第二卡爪422，第一卡爪421的一端为固定端、且与转向连接件400连接，第一卡爪421的另一端为自由端，第二卡爪422的一端为固定端、且与转向 连接件400连接，第一卡爪421的另一端为自由端。第一卡爪421的自由端设置有用于与灯具卡扣配合的第一卡扣凸起421a，第一卡扣凸起421a位于第一卡爪421朝向第二卡爪422的一侧；第二卡爪422的自由端设置有用于与灯具卡扣配合的第二卡扣凸起422a，第二卡扣凸起422a位于第二卡爪422朝向第一卡爪421的一侧。相对应的，与转向连接件400相连接的灯具上需要具有与第一卡扣凸起421a和第二卡扣凸起422a卡扣配合的卡槽，在具体的工作过程中，通过按压第一卡爪421和第二卡爪422，第一卡爪421和第二卡爪422相向靠拢并顺利插接入灯具上的卡槽中，不再按压第一卡爪421和第二卡爪422，第一卡爪421和第二卡爪422复位，第一卡扣凸起421a和第二卡扣凸起422a卡扣配合在卡槽内，实现转向连接件400与灯具的固定装配，进而可以通过转动第一转向单元100(第二转向单元200)以及与第一转向单元100(第二转向单元200)转动连接的转向连接器400，就可以使得灯具在两个维度平面内实现自由转动。
现有的连接器在使用时，会阻挡光的传播，从而形成暗区，会破坏灯具的发光均匀性。基于此，在较为优选的方案中，第一转向单元100、第二转向单元200、中心转轴300和转向连接件400均可以为光扩散PC材料件。光扩散PC材料件具有高透光、高扩散、无眩光、无光影的优点，可减少对灯具的发光的阻挡，避免形成暗区，有效保障灯具的发光均匀性。
基于本发明实施例公开的连接器，本发明实施例还公开一种灯具系统，请参考图7，所公开的灯具系统包括上位实施例所述的连接器，以及通过该连接器装配的至少两个灯具500。具体的，灯具500具有第二卡槽510，当连接器通过连接部420连接灯具500时，第一卡爪421和第二卡爪422卡扣配合于第二卡槽510，进一步地，第一卡扣凸起421a和第二卡扣凸起422a卡扣配合在第二卡槽510内。
本发明实施例公开的灯具500可以为线条灯具，也可以为其他的灯具，例如蜡烛灯等，本发明实施例也不限制灯具的具体种类。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
