图1是本发明实施例提供的一种遥控器的分解结构示意图。图2是本发明实施例提供的一种遥控器的组装结构示意图。
如图1和图2所示，本发明实施例的遥控器包括遥控器主体10和旋转支架30，旋转支架30将遥控器主体10和显示屏20转动连接。其中，图1所示的遥控器的显示屏20与遥控器主体10之间角度较大，具体为显示屏20相对于遥控器主体10打开，而图2所示的遥控器的显示屏20与遥控器主体10之间的角度较小，具体为显示屏20盖合在遥控器主体10上。
请结合图1和图3，图3是本发明实施例提供的一种遥控器中旋转支架一个角度的分解结构示意，旋转支架30包括转动臂40、底座50以及阻尼转轴60，底座50固定在遥控器主体10上，显示屏20固定在转动臂40上，阻尼转轴60将转动臂40转动连接在底座50上。因此，转动臂40可以相对于底座50发生转动，从而使得显示屏20可以相对于遥控器主体10发生转动。
在一些实施例中，显示屏20和遥控器主体10之间进行电性连接，其走线可以从遥控器主体10经过旋转支架30到达显示屏20，如图4所示，图4是本发明实施例提供的一种遥控器的走线示意图。
请参阅图5和图6，图5是本发明实施例提供的一种遥控器中阻尼转轴的分解结构示意图。图6是本发明实施例提供的一种遥控器中阻尼转轴的组装结构示意图。阻尼转轴60包括旋转轴62和套设在旋转轴62的一端的第一摩擦片64、第二摩擦片66和第三摩擦片68。其中，旋转轴62与第二摩擦片66之间能够相对转动。第一摩擦片64和第三摩擦片68随旋转轴62的转动而转动。第一摩擦片64和第三摩擦片68分别抵接第二摩擦片66的两侧，以使第一摩擦片64和第二摩擦片66之间以及第三摩擦片68和第二摩擦片66之间均产生摩擦阻力。
本实施例的阻尼转轴60与转动臂40和底座50的连接关系如下：转动臂40连接在旋转轴62上，第二摩擦片66固定在底座50上，从而使得转动臂40可以相对于底座50发生转动。
举例而言，当需要将显示屏20与遥控器主体10之间的角度调大 的时候，用户可以直接将显示屏20向上转动，由于显示屏20固定在转动臂40上，因而，转动臂40会随着显示屏20向上转动，转动臂40带动旋转轴62发生转动，此时，第一摩擦片64和第三摩擦片68随着旋转轴62转动，而第二摩擦片66不随旋转轴62转动。
当显示屏20调整到所需的角度时，停止转动显示屏20，此时，由于第一摩擦片64抵接第二摩擦片66的一侧，第三摩擦片68抵接第二摩擦片66的另一侧，从而使得第一摩擦片64和第二摩擦片66之间以及第三摩擦片68和第二摩擦片66之间均产生摩擦阻力，该摩擦阻力阻止第一摩擦片64和第二摩擦片66之间以及第三摩擦片68和第二摩擦片66之间继续发生转动，使得旋转轴62不会相对第二摩擦片66发生转动，从而使得转动臂40也不会相对于底座50发生转动，进而使得显示屏20也不会相对于遥控器主体10发生转动，从而使显示屏20可以在稳定停止在该所需的角度。
区别于现有技术，本发明实施方式中通过采用第一摩擦片64和第三摩擦片68对第二摩擦片66的抵接产生的摩擦阻力来控制显示屏20与遥控器主体10之间的角度，使得显示屏20在允许转动的范围内，可以在任意位置稳定停止，使得用户的操作更加方便，并且，该摩擦阻力稳定，增强了遥控器的耐久性和转动性能，同时保证用户在转动时有很好的手感。此外，阻尼转轴60的体积小、结构简单、加工简单且装配便捷，从而使整个旋转支架30的体积得以减小，进而减小了整个遥控器的体积，简化了遥控器的结构，降低了造价。
在其他实施例中，所述第一摩擦片64和所述第三摩擦片68两者 中可省略一个，只要与所述第二摩擦片66之间的摩擦阻力足够大，同样能够达到使所述显示屏20在转动的范围内在任意位置稳定停止的效果。
具体而言，本实施例的第二摩擦片66包括套接部662和沿旋转轴62凸出的连接片664，套接部662转动套设在旋转轴62上，连接片664固定在底座50上。
具体地，本实施例的连接片664沿旋转轴62的径向凸出，本实施例的连接片664呈U形，当然，在其他一些实施例中，该连接片664还可以呈方形等其他形状。
在一个实施例中，第一摩擦片64、第二摩擦片66和第三摩擦片68可以由金属制成，金属的耐摩性较强，从而能进一步提高阻尼转轴的耐久性。为了降低金属之间摩擦而产生的噪音，在一些实施例中，第一摩擦片64和第二摩擦片66的抵接面之间以及第三摩擦片68和第二摩擦片66的抵接面之间还设有油脂层(图未示)，从而避免在转动时产生金属摩擦的声音。
阻尼转轴60还包括至少一个弹性压持件61，弹性压持件61套设在旋转轴62上并用于从第一摩擦片64或第三摩擦片68的远离第二摩擦片66的一侧将第一摩擦片64、第二摩擦片66和第三摩擦片68弹性压持成依次抵接，从而增大了第一摩擦片64与第二摩擦片66之间以及第三摩擦片68和第二摩擦片66之间的摩擦阻力。在本实施例中，弹性压持件61随旋转轴62的转动而转动。
弹性压持件61可以是螺旋弹簧或者扭杆弹簧等，本实施例的弹 性压持件61为碟形弹簧。本实施例中，弹性压持件61的数量是2个，在其它一些实施例中，弹性压持件61的数量还可以是1个、3个或者更多。
第一摩擦片64和第二摩擦片66与旋转轴62的固定方式有多种，例如，可以是胶接、焊接或者卡接等。本实施例中的第一摩擦片64和第二摩擦片66均卡接在旋转轴62上。
具体而言，沿旋转轴62轴向的至少部分区域为具有至少一轴向卡接面620的圆柱体。
第一摩擦片64上设有安装孔640，第三摩擦片68上设有安装孔680，第一摩擦片64通过安装孔640套接在圆柱体上，第三摩擦片68通过安装孔680套接在圆柱体上，安装孔640和安装孔680与旋转轴62的截面形状相匹配，以使第一摩擦片64和第三摩擦片68卡接于圆柱体上。
例如，本实施例的旋转轴62上设置有两个相对称的卡接面620，安装孔640和安装孔680呈对称的圆缺形设置，使安装孔640和安装孔680的内壁均抵接在旋转轴62的轴向侧面上，因而使第一摩擦片64和第三摩擦片68卡接在旋转轴62上，从而使第一摩擦片64和第三摩擦片68随旋转轴62的转动而转动。
同理，弹性压持件61上也设有装配孔610，该装配孔610呈对称的圆缺形设置，使装配孔610的内壁均抵接在旋转轴62的轴向侧面上，因而使弹性压持件61卡接在旋转轴62上，从而使弹性压持件61随旋转轴62的转动而转动。
第二摩擦片66上设有通孔660，该通孔660呈圆形设置，第二摩擦片66通过通孔660套接在旋转轴62上并能够绕旋转轴62转动。
旋转轴62的一端为基部622，另一端为轴杆部624，第一摩擦片64、第二摩擦片66和第三摩擦片68均套设在基部622上，转动臂40连接在轴杆部624上，基部622和轴杆部624的连接处设有止挡部63，以限定第一摩擦片64、第二摩擦片66和第三摩擦片68的位置。
图7和图8，图7是本发明实施例提供的一种遥控器中旋转支架另一个角度的分解结构示意图。图8是本发明实施例提供的一种遥控器中旋转支架的组装结构示意图。
具体而言，底座50包括同轴且彼此间隔设置的第一套筒52和第二套筒54，转动臂40上设有第三套筒42，第三套筒42安装在第一套筒52和第二套筒54之间。第一套筒52、第三套筒42和第二套筒54依次套设于旋转轴62上，第一套筒52和第二套筒54能够绕旋转轴62转动，第二摩擦片66固定在第一套筒52内，第三套筒42固定于旋转轴62上，从而将转动臂40转动连接在底座50上。
本实施例中，第三套筒42内设有配合孔420，配合孔420呈对称的圆缺形设置，使配合孔420的内壁均抵接在旋转轴62的轴向侧面上，因而使第三套筒42卡接在旋转轴62上，从而使第三套筒42随旋转轴62的转动而转动。
本实施例的旋转轴62上与第三套筒42连接的位置处的曲面上设有防滑纹路626，用于进一步加固第三套筒42和旋转轴62之间的 连接。
在一些实施例中，第一套筒52的内壁上设有朝向第一套筒52内凸出的台阶部520，连接片664和台阶部520卡接，从而将第二摩擦片66固定在第一套筒52内。
在另一些实施例中，第一套筒52靠近第二套筒54的一侧设有端壁51，端壁51上设有螺纹孔510，连接片664上设有连接孔。螺钉70穿设于连接片664的连接孔内而将第二摩擦片66固定在第一套筒52内。在本实施例中，U形连接片664中间的间隙可以作为所述连接孔。
本实施例中，第二摩擦片66同时通过连接片664与台阶部520的卡接以及螺钉70的螺接固定在第一套筒52内，使得遥控器的结构更加稳定。
具体地，本实施例的台阶部520为间隔设置的两个，并分别与U形连接片664的两侧卡接。
第一套筒52远离第二套筒54的一侧设有第一端盖53，用于封盖第一套筒52，同时端壁51和第一端盖53配合将第一摩擦片64、第二摩擦片66和第三摩擦片68压紧在第一套筒52内。第二套筒54远离第一套筒52的一侧设有第二端盖55，用于封盖第二套筒54。
值得一提的是，在一个实施例中，阻尼转轴60还包括预紧垫片65，如图5所示，预紧垫片65套设在基部620的端部，并可随旋转轴62的转动而转动，预紧垫片65抵接与其相邻的元件，从而进一步压紧第一摩擦片64、第二摩擦片66和第三摩擦片68。例如，本实施 例中，基部620从靠近止挡部63的一端到基部620的另一端部依次套接有：第三摩擦片68、第二摩擦片66、第一摩擦片64、两个弹性压持件61和预紧垫片65，该预紧垫片65抵接与其相邻的弹性压持件61，使弹性压持件61进一步抵紧第一摩擦片64，预紧垫片65设置在基部620的端部还能对弹性压持件61其保护作用。
本发明的遥控器的阻尼转轴60体积小，结构简单，可以简单装配后使用，该阻尼转轴60可以为旋转支架30提供稳定的摩擦阻力，使得用户转动遥控器的显示屏20使能有很好的手感，本发明的遥控器的显示屏20在允许转动的范围内，可以在任意位置稳定停止，并且，该阻尼转轴60的耐久性强，例如，实验表明，该阻尼转轴60在转动了1万次后，仍然保持有85％-90％的摩擦阻力，同时，由于该阻尼转轴60的结构简单，因而加工工艺也简单，其造价是市场现存类似转轴的1/3-1/5。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
