为了使本申请的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本申请进行详细描述。
在此，需要说明的是，为了避免因不必要的细节而模糊了本申请，在附图中仅仅示出了 与本申请的方案密切相关的结构和/或处理步骤，而省略了与本申请关系不大的其他细节。
另外，还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。
请参阅图1-2所示，为本申请一优选实施例的台灯100，台灯100包括灯头10、灯臂20及底座30。灯头10与灯臂20连接，灯臂20与底座30通过多角度旋转装置40连接，使得灯臂20可以带动灯头10相对底座30上下转动和左右转动，实现台灯100对不同方向的照明，提高台灯100的照明空间范围和用户体验。
在本实施例中，灯头10与灯臂20通过转动轴11连接。该转动轴11为上下转动轴，以使得灯头10可以相对灯臂20上下摆动，以提高台灯100的照明方向。在其他实施例中，该转动轴11也可以为左右转动轴，使得灯头10可以相对灯臂20左右转动，或者，灯头10与灯臂20也可以旋转连接，以使得灯头10可以相对灯臂20实现360°旋转，或者，灯头10与灯臂20固定连接。本申请对此不予限制。
灯臂20与底座30通过多角度旋转装置40连接。请参阅图3-6并结合图1-2所示，本申请提供了一种多角度旋转装置40，包括第一连接件41和第二连接件42。第一连接件41与灯臂20转动连接且二者的转动连接处具有一沿水平延伸的第一轴心线，配置为使灯臂20能够相对第一连接件41绕第一轴心线45在竖直方向上转动，即，使得灯臂20能够相对第一连接件41绕第一轴心线45上下摆动。第二连接件42与底座30固定连接，且第二连接件42设置在第一连接件41的下方，与第一连接件41转动连接，在第一连接件41与第二连接件42的转动连接处具有一沿竖直延伸的第二轴心线46，配置为使第一连接件41能够相对第二连接件42绕第二轴心线46在水平方向上转动。如此设置，使得灯臂20能够相对第一连接件41绕第一轴心线45上下摆动，同时第一连接件41设置在第二连接件42的上方，能够相对第二连接件42绕第二轴心线46在水平方向上转动，使得灯头10能够随着灯臂20实现上下左右旋转，即，通过多角度旋转装置40实现灯臂20与底座30之间的多维度调节，提高台灯100的照明空间范围和用户的体验。
在本实施例中，第一连接件41包括旋转基座411、自旋转基座411向背离第二连接件42方向延伸的连接部412及自旋转基座411向靠近第二连接件42方向延伸的旋转轴413。连接部412与灯臂20通过水平方向设置的转轴组件43转动连接，而竖直方向延伸的旋转轴413插入第二连接件42中，与第二连接件42转动连接。即，通过第一连接件41同时连接灯臂20和第二连接件42，由于第一连接件41与灯臂20通过水平方向设置的转轴组件43转动连接，使得灯臂20可以相对第一连接件41上下摆动，进而实现灯头10的上下摆动，由于第一连接件41相对第二连接件42能够以旋转轴413为旋转中心45在水平方向上左右转动，且第二连接件42与底座30固定连接，因此，第一连接件41可以相对第二连接件42 左右转动，从而使得灯臂20带动灯头10可以相对底座30左右转动，实现台灯100在多个方向上的照明。需要知道的是，在本实施例中，第一轴心线45与转轴组件43的轴心线相重合，第二轴心线46与旋转轴413的轴心线重合。也就是说，在本实施例中，第一连接件41与灯臂20通过实体轴(转轴组件43)转动连接，第一连接件41与第二连接件42通过实体轴(旋转轴413)转动连接。在其他实施例中，该第一轴心线45也可以为非实体的轴心线，和/或，第二轴心线46也可以为非实体的轴心线(例如，当第一连接件41和第二连接件42在竖直方向上通过导轨和导槽滑动连接时，该第二轴心线46即为非实体的轴心线)，本申请对此不予限制。
连接部412包括一对侧壁4121及连接一对侧壁4121的连接壁4122，一对侧壁4121与连接壁4122之间围设形成有收容槽4123。可选地，连接部412设置在旋转基座411的中部，且一对侧壁4121与旋转基座411的边缘具有一定的距离，以为后续安装装饰盖50提供安装空间。
转轴组件43包括转轴431和套设在转轴431上的阻尼组件432，阻尼组件432能够使得转动连接部21相对第一连接件41转动时产生摩擦阻力，可以保持灯臂20在转动范围的任意角度位置止动或止转。一对侧壁4121上设有第一转动孔4124，转轴431穿过第一转动孔4124，并通过阻尼组件432将转轴431与一对侧壁4121固定连接，实现转轴431与连接部412的相对固定。
进一步地，灯臂20朝向第一连接件41的一侧设有与灯臂20成角度设置的转动连接部21。转动连接部21包括朝向第一连接件41设置的两个凸耳，两个凸耳之间半包围连接，其具有开口的部分朝向第一连接件41设置，为灯臂20的上下转动提供避让空间。转动连接部21的两个凸耳上设有第二转动孔211，转轴组件43穿过第一转动孔4124与第二转动孔211实现灯臂20与第一连接件41的转动连接。即灯臂20通过转轴组件43可以相对第一连接件41上下转动。需要知道的是，在本实施例中，转动连接部21通过螺栓等固定件固定连接在与灯臂20垂直的方向上，即转动连接部21与灯臂20分体设置，通过固定件固定连接，且转动连接部21与灯臂20之间的夹角为直角。在其他实施例中，转动连接部21可以与灯臂20一体成型设置，和/或，转动连接部21与灯臂20之间的夹角也可以为锐角或钝角，或，灯臂20不单独设置转动连接部21，而通过灯臂20直接转动连接在转轴组件43的转轴431上，实现灯臂20与第一连接件41之间的转动连接，本申请对此不予限制。
收容槽4123内还设有弹性止位件44，弹性止位件44套设在转轴431上，且一端限位在收容槽4123内，另一端限位在灯臂20内，通过弹性止位件44和上述的阻尼组件432，使得灯臂40的转动更加省力轻便，且能够实现灯臂20的随转随止。
优选地，弹性止位件44为扭簧。在收容槽4123内设有向上延伸的限位板，转动连接部21内设有限位槽(未图示)，扭簧的一端被限位板限位在收容槽4123内，另一端限位固定在限位槽内。当灯臂20上下转动时，通过扭簧的弹力以抵消灯臂20及灯头10的重量，从 而实现灯臂20的随转随止。
在本实施例中，第一转动孔4124包括设置在其中一个侧壁4121上的圆孔4124a和设置在另一个侧壁4121上的偏平孔4124b。转轴431为螺钉，包括螺头和螺杆，螺杆包括同轴设置的第一部分和第二部分，第一部分靠近螺帽4321设置，且第一部分的直径大于第二部分的直径。阻尼组件432包括螺帽4321、多个摩擦垫片4322以及与偏平孔4124b配合的止位片4323。在将灯臂20组装至第一连接件41上时，螺钉带有螺头的一端穿过侧壁4121上的圆孔4124a，并依次穿过一个摩擦垫片4322、一个凸耳211上的第二转动孔213、扭簧的中心孔、另一个凸耳211上的第二转动孔213、至少一个摩擦垫片4322、侧壁4121上的扁平孔以及止位片4323后，被螺帽4321固定。如此设置，使得转轴431通过阻尼组件432与第一连接件41固定连接，当灯臂20受到外力相对第一连接件41上下转动时，转轴431与第一连接件41保持相对静止。进一步地，由于阻尼组件432的两个摩擦垫片4322分别设置在两个凸耳211的两侧，也可以通过摩擦力以辅助弹性止位件44固定灯臂20。即，当灯臂20上下转动到合适位置，阻尼组件432和弹性止位件44共同作用以保持灯臂20的固定，防止灯臂20的滑动，进而防止灯头10滑动。
请参阅图3-6所示，第一连接件41的旋转基座411向靠近第二连接件42方向延伸形成有旋转轴413，该旋转轴413用以与第二连接件42连接，同时第一连接件41相对第二连接件42绕旋转轴413在水平方向上转动。
第二连接件42对应旋转轴413的位置设有容纳部4211，旋转轴413插入容纳部4211内且至少部分外露于容纳部4211，外露于容纳部4211的部分设有螺纹，即旋转轴413远离旋转基座411的一端设有螺纹，用于与紧固组件414连接，实现第一连接件41和第二连接件42的转动连接。紧固组件414包括螺母及摩擦垫片4322。旋转轴413穿过第二连接件42上的容纳部4211与螺母螺纹连接，以将第二连接件42限位，实现第一连接件41和第二连接件42的转动连接。通过设置摩擦垫片4322，使得第二连接件42与旋转轴413之间产生静摩擦力，使得第一连接件41在转动范围的任意角度位置保持止动或止转。当无外力作用时，第一连接件41与第二连接件42通过静摩擦力是保持相对静止的。当第一连接件41受到的外力大于静摩擦力时，第一连接件41能够相对第二连接件42绕旋转轴413在水平方向上周向转动。如此，当第一连接件41相对第二连接件42左右转动到合适位置时，通过紧固组件414与旋转轴413之间的静摩擦力使得第一连接件41与第二连接件42保持相对静止，进而以保持灯臂20的固定，防止灯臂20的滑动，进而防止灯头10滑动，实现台灯100的随转随止。
请参阅图6并结合图3-5所示，第二连接件42包括承载基座421及自承载基座421向底座30方向延伸的固定臂422。其中，承载基座421用于与第一连接件41转动连接，固定臂422用于与底座30固定连接。
容纳部4211设置在承载基座421上，且在容纳部4211的外周设有向第一连接件41方 向延伸的凸肋4212。凸肋4212与承载基座421的边缘之间具有台阶部4213。第一连接件41套设在凸肋4212的外侧并与台阶部4213滑动连接。通过设置凸肋4212，以限位第一连接件41的转动方向和转动角度，避免第一连接件41从台阶部4213上脱落下来。
进一步地，旋转基座411朝向第二连接件42的一侧设有第一限位件4111，第二连接件42朝向旋转基座411的一侧设有第二限位件4214，通过第一限位件4111与第二限位件4214限定第一连接件41相对第二连接件42周向转动的角度。
具体地，第一限位件4111为设置在旋转基座411上向第二连接件42方向延伸的两个凸起，第一连接件41通过第一限位件4111与台阶部4213滑动连接。第二限位件4214设置在台阶部4213上，为向第一连接件41方向延伸的凸块，且该凸块与凸肋4212连接，用以限制第一连接件41的转动角度。
固定臂422与底座30固定连接，包括弧形部4221与设置在弧形部4221两侧的固定部4222。其中，固定部4222上设有固定孔4223，用于与底座30固定连接。而弧形部4221则为紧固组件414与旋转轴413的连接提供了安装空间。
请参阅图7并结合图1-6所示，底座30包括底盘31和支架32。底盘31的一侧与待放置面接触，其上设有防滑垫，以提高台灯200在待放置面上的稳定性。优选地，该待放置面包括但不限于桌面。支架32自底盘31背离待放置面的一侧向灯臂20的方向延伸，且与底盘31倾斜设置。支架32朝向第二连接件42的一侧设有安装部321和让位部322。第二连接件42的承载基座421连接在安装部321的上方，且第二连接件42的固定臂422及至少部分容纳部4211穿过让位部322收容在支架32内，以减少台灯100的占用空间，提高台灯100的外观美观性。
请参阅图8并结合图1-6，台灯100还包括装饰盖50，装饰盖50上设有与转动连接部21形状匹配的避让部51，以当灯臂20上下转动时，为灯臂20提供避让空间。
装饰盖50设置在底座30的支架32与转动连接部21之间，并与多角度旋转装置40固定连接。具体地，装饰盖50内设有空心固定柱，第一连接件41上设有连接孔，螺丝等紧固件穿过连接孔与空心固定柱，以将装饰盖50固定在第一连接件41上。
进一步地，装饰盖50具有容纳空间52，多角度旋转装置40及部分转动连接部21收容在容纳空间52内，以提高台灯100的美观性，同时避免灰尘进入多角度旋转装置40内，提高多角度旋转装置40的寿命，进而提高台灯100的寿命。
本申请的台灯100的多角度的调节方式为：当需要上下调节台灯100时，仅需要转动转轴组件43，使得灯臂20可以相对第一连接件41上下摆动，进而实现灯头10的上下摆动。当需要左右调节台灯100时，仅需要转动第一连接件41，使得第一连接件41可以相对第二连接件42左右旋转，进而带动灯臂20及灯头10左右旋转。
综上所述，本申请的多角度旋转装置40及台灯100结构简单，通过将第一连接件41与灯臂20设置为转动连接且二者的转动连接处具有一沿水平延伸的第一轴心线45，使灯臂 20能够相对第一连接件41绕第一轴心线45在竖直方向上转动，通过将第二连接件42设置在第一连接件41的下方，且与第一连接件41转动连接，在第一连接件41与第二连接件42的转动连接处具有一沿竖直延伸的第二轴心线46，使第一连接件41能够相对第二连接件42绕第二轴心线向在水平方向上转动，通过将第二连接件42设置为与底座30固定连接，且第一连接件与灯臂转动连接，使得灯臂可以带动灯头相对第一连接件在竖直方向上转动，且在使第一连接件41相对第二连接件42在水平方向上转动时，第一连接件41能够带动灯臂20及灯头10相对底座30在水平方向左右旋转，实现灯臂20与底座30之间的多维度调节，使得灯头10能够随着灯臂20实现上下左右旋转，提高台灯100的照明空间范围和用户的体验。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
