旋转支架、旋转支架的组装方法及应用该旋转支架的耳机 技术领域
本发明属于耳机技术领域，更具体地说，是涉及一种旋转支架、旋转支架的组装方法及应用该旋转支架的耳机。
背景技术
现有的头戴式耳机包括旋转支架以及安装在旋转支架两端部的耳机体，其中，旋转支架包括头带以及连接于头带两端的支臂，而各耳机体分别安装在与其对应的支臂上，各耳机体分别安装在一支臂上，为了便于头戴式耳机的收纳，通常头带与各支臂之间直接通过转动轴转动连接，而头带和支臂均与转动轴过盈配合，通过与转动轴之间产生的摩擦力控制转动的位置，这样，便可使各支臂带动耳机体一起转向头带，当需要使用头戴式耳机时，只需将各支臂转离头带即可。例如，专利申请号为US14/899021、发明名称为“Headphone”的美国专利文献，即公开一种头戴式耳机，头戴式耳机的各支臂通过一转动轴与头戴式耳机的头带的端部转动连接，可实现展开与折叠。但是，这样的转动连接结构占用空间较大；而且无论是折叠状态，还是展开状态，皆会看到转动轴，影响整体的美观性；最主要的是，头带和各支臂均与转动轴紧密配合，这会造成该转动连接结构装卸不便，而且还会装卸过程中，因紧密配合的缘故，会对产品的外型造成很大的伤害。
发明内容
本发明的目的在于提供一种旋转支架、旋转支架的组装方法及应用该旋转支架的耳机，以解决现有技术中存在旋转支架上的转动连接结构占用空间大、影响整体外观，而且装卸过程中，因紧密配合的缘故，会对旋转支架的外型造 成很大的伤害的技术问题。

本发明的目的还在于提供一种旋转支架的组装方法，该组装方法包括：
预备旋转支架：预备一旋转支架，所述旋转支架包括第一支架、第二支架、固定件和旋转连接件，所述固定件包括固定主体，所述固定主体具有第一连接端以及与所述第一连接端相对的第二连接端，所述固定主体还具有安装腔以及与所述安装腔连通的插接口和转接口，所述转接口设于所述第一连接端并由所述第一连接端延伸至所述固定件的上侧壁，所述插接口设于所述第二连接端，所述第一支架具有转接端部，所述第二支架具有插接端部；

第二次旋转调位：将所述第一支架的转接端部转至所述固定主体的第一连接端，使所述第一支架具有展开状态；
第三次组装：将所述第二支架的插接端部穿过所述插接口，当所述第一支架的转接端部沿着所述转接口转至所述固定主体的侧部时，所述第一支架具有折叠状态；
固定：将所述插接端部与所述固定主体固定连接。
本发明的目的还在于提供一种耳机，包括如上述的旋转支架。
本发明提供的一种旋转支架、旋转支架的组装方法及应用该旋转支架的耳机的有益效果在于：旋转支架包括第一支架、第二支架、固定件和旋转连接件，第一支架的转接端部与旋转连接件转动连接，旋转连接件经由转接口安装在安装腔并限位在安装腔，与此同时，第一支架的转接端部也经由转接口插于安装腔，转接口是固定主体中由第一连接端向上侧壁开设而形成的开口，第一支架的转接端部可沿转接口的延伸方向转动；第二支架的插接端部穿过第二连接端的插接口并固定于安装腔内，当第一支架的转接端部转至第一连接端时，第一支架处于展开状态；当第一支架的转接端部沿着转接口转至固定主体的上侧时，第一支架处于折叠状态。这样，通过该旋转支架，摒弃了第一支架与第二支架之间直接通过转接轴进行转动连接，而且通过旋转连接件与固定件的加入，方便第一支架与第二支架的组装与拆卸，即组装时，只需将旋转连接件与第一支架的转接端部转动连接在一起，再将旋转连接件经由转接口安装并限位在固定件的安装腔，最后将第二支架的插接端部经由插接口***安装腔并与固定件固定连接，实现旋转支架的安装；拆卸时，只需将组装步骤倒过来操作即可。这样，一方面，组装后的旋转结构隐藏在安装腔，不会外露，提高旋转支架整体的美观性；另一方面，第一支架与旋转连接件单独组装与拆卸，不会对第一支架和第二支架的外形造成伤害；再有，整体结构简单，转接结构紧凑，占用空 间小，提高用户对其的体验性。

实施例一：
请同时参阅图1至图4，本发明实施例一提供一种旋转支架，其包括第一支架100、第二支架200、固定件300和旋转连接件400，其中，固定件300包括固定主体310，固定主体310具有第一连接端311以及与第一连接端311相对的第二连接端312，固定主体310还具有安装腔301以及与安装腔301连通的插接口302和转接口303，转接口303设于第一连接端311并由第一连接端311延伸至固定主体310的上侧壁，插接口302设于第二连接端312。
第一支架100具有转接端部110，转接端部110与旋转连接件400转动连接，旋转连接件400穿过转接口303并限位于安装腔301，转接端部110穿过转接口303并插于安装腔301。可以理解地，第一支架100的转接端部110与旋转连接件400转动连接，旋转连接件400由转接口303安装在安装腔301并限位在安装腔301，与此同时，第一支架100的转接端部110也经由转接口303插于安装腔301，转接口303是固定主体310中由第一连接端311向固定主体310的侧壁开设而形成的开口，第一支架100的转接端部110可沿转接口303的延伸方向转动。
第二支架200具有插接端部210，插接端部210穿过插接口302并固定于安装腔301内。
当第一支架100的转接端部110转至第一连接端311时，第一支架100具有展开状态；当第一支架100的转接端部110沿着转接口303转至固定主体310的上侧时，第一支架100具有折叠状态。
在本实施例中，旋转支架1包括第一支架100、第二支架200、固定件300和旋转连接件400，第一支架100的转接端部110与旋转连接件400转动连接，旋转连接件400经由转接口303安装在安装腔301并限位在安装腔301，与此同时，第一支架100的转接端部110也经由转接口303插于安装腔301，转接口303是固定主体310中由第一连接端311向上侧壁开设而形成的开口，第一支架100的转接端部110可沿转接口303的延伸方向转动；第二支架200的插接端部210穿过第二连接端312的插接口302并固定于安装腔301内，当第一支架100的转接端部110转至第一连接端311时，第一支架100处于展开状态；当第一支架100的转接端部110沿着转接口303转至固定主体310的上侧时，第一支架100处于折叠状态。这样，通过该旋转支架1，摒弃了第一支架100与第二支架200之间直接通过转接轴进行转动连接，而且通过旋转连接件400与固定件300的加入，方便第一支架100与第二支架200的组装与拆卸，即组装时，只需将旋转连接件400与第一支架100的转接端部110转动连接在一起，再将旋转连接件400经由转接口303安装并限位在固定件300的安装腔301，最后将第二支架200的插接端部210经由插接口302***安装腔301并与固定件300固定连接，实现旋转支架1的安装；拆卸时，只需将组装步骤倒过来操作即可。这样，一方面，组装后的旋转结构隐藏在安装腔301，不会外露，提高旋转支架1整体的美观性；另一方面，第一支架100与旋转连接件400单独组装与拆卸，不会对第一支架100和第二支架200的外形造成伤害；再有，整体结构简单，转接结构紧凑，占用空间小，提高用户对其的体验性。
在本实施例中，固定主体310于第一连接端311端面的两侧部分别开设有连接孔304，各连接孔304皆与安装腔301连通。第二支架200的插接端部210于其插接端面的两侧部开设有固定孔201，当插接端部210插于安装腔301时，各连接孔304分别与一固定孔201相对，通过连接件的一端部由外部穿过连接孔304并锁紧在相应的固定孔201内，实现插接端部210与固定件300之间的固定连接。
请同时参阅图1和图2，进一步地，旋转连接件400包括依次对接在一起的第一限位部410、转接部420和第二限位部430，第一支架100的转接端部110与转接部420转动连接；第一限位部410和第二限位部430均限位于安装腔301内。
请同时参阅图2和图5，进一步地，固定件300还包括由固定主体310的安装腔301腔壁凸伸而成的限位台320，限位台320临近第一连接端311设置，限位台320于其台面开设有限位槽321，限位槽321的槽口朝向第二连接端312。
第一限位部410包括一端与转接部420连接的限位插板411，限位插板411的另一端插于限位槽321内。这样，有效防止限位插板411朝向转接口303以及第一连接端311方向发生移位。
在本实施例中，限位插板411于与第一连接端311相对的板边开设有两个插槽401，两插槽401之间的板体插于限位槽321内，而限位台320的两侧端面分别插于两插槽401内。
请同时参阅图2和图6，进一步地，第二支架200的插接端部210于其下表面开设有延伸至插接端的限制槽202，第二限位部430插于限制槽202。可以理解地，旋转连接件400安装于固定主体310的安装腔301，此时，第二限位部430的上表面与固定主体310的安装腔301的上腔壁之间形成插接空间，第二支架200的插接端部210由插接口302***该插接空间，第二限位部430在插接端部210逐渐***安装腔301的同时也逐渐***限制槽202，直至第二限位部430抵于限制槽202的端壁时，将第二支架200的插接端部210与固定主体310固定连接。这样，结合限位槽321的设置，实现对旋转连接件400的限位，即实现对旋转连接件400的固定。
在本实施例中，插接端部210于限制槽202的槽底凸伸有至少两个支撑条220，至少两个支撑条220间隔布设，且皆沿第二限位部430与限制槽202插接的插接方向延伸，这样，降低第二限位部430与限制槽202的槽底接触面积，降低磨损。具体地，各支撑条220于其插接端的端面开设有导向斜面，这样， 便于第二限位部430顺利且快速地插接到位。
在本实施例中，第二限位部430为限位板。
请同时参阅图2、图4和图6，进一步地，第二支架200的插接端部210于其上表面开设有容置槽203，转接端部110插于容置槽203。这样，可使旋转支架1整体结构更加紧凑。
请同时参阅图2、图4和图6，进一步地，第二支架200的插接端部210于其端面向另一端面开设有避让槽204，避让槽204上下贯通，转接部420插于避让槽204。这样，更进一步缩小旋转支架1的转接结构占用的空间，结构更加紧凑。
请同时参阅图2、图4和图5，进一步地，转接部420包括两端分别连接第一限位部410和第二限位部430的桥接板421以及由桥接板421相对两侧部向上延伸成型的转接脚422。两转接脚422与转接端部110通过转接轴(图中未示出)转动连接。在本实施例中，避让槽204间隔开设有两个，各转接脚422分别插于一避让槽204，且各转接脚422的自由端部皆由相对应的避让槽204穿出，并与转接端部110通过转接轴转动连接。具体地，桥接板421的两端分别与限位板的一端和限位插板411的一端对接，且三者共同形成支撑板。
请同时参阅图1和图5，进一步地，第一限位部410还包括由限位插板411的两相对侧部分别向上延伸成型的限位卡脚412，两限位卡脚412于其自由端部相向设有卡位凸起413。在本实施例中，两限位卡脚412的自由端部相向凹陷形成所述的卡位凸起413。
转接端部110于其两侧分别设有卡位槽101。
在本实施例中，当第一支架100处于展开状态时，各卡位凸起413分别插于一卡位槽101，实现展开状态时对第一支架100进行限位，使第一支架100相对于第二支架200处于展开状态。当第一支架100处于转动过程时，各卡位凸起413分别抵于转动端部的一侧，且两限位卡脚412共同夹紧转动端部，这样，当第一支架100相对于第二支架200转动时，第一支架100受到两个限位 卡脚412共同夹持作用，使转动过程中产生一定的摩擦力，这样可使第一支架100相对第二支架200转动时的转动力(外部施加的力)均匀。当第一支架100处于折叠状态时，两限位卡脚412相向收拢并共同抵于第一支架100的底面，实现折叠状态时对第一支架100进行限位，使第一支架100相对于第二支架200保持折叠状态。
请同时参阅图2以及图5至图7，进一步地，固定主体310于其下腔壁沿着插接端部210的插接方向设有导向槽305，旋转连接件400于其下表面设有与导向槽305相匹配的导向凸起440，导向凸起440插于导向槽305并与导向槽305滑接配合。这样，便于旋转连接件400定位安装到位。在本实施例中，导向槽305为V型槽，当然并不仅限于此，还可以为U型槽，只要能满足旋转连接件400能实现定位安装即可。具体地，旋转连接件400的支撑板由上向下凹陷形成所述的导向凸起440，同时，该支撑板的上部形成引导槽402。
在本实施例中，第二支架200的插接端部210于限制槽202的槽底凸设有引导凸起230，该引导凸起230与旋转连接件400上的引导槽402相匹配，这样，便于插接端部210快速且精准地安装到位，提高组装效率。
请同时参阅图2和图8，进一步地，第一支架100包括主架体120和托架130，主架体120包括板体121以及与板体121的一端连接的转接头122，托架130包括托板131以及与托板131的一端连接的卡接头132，卡接头132固定于转接头122且与卡接头132共同形成转接端部110，托板131相对位于板体121的下方并与板体121层叠在一起且二者可拆卸连接，旋转连接件400与转接头122转动连接。在本实施例中，托板131与板体121之间卡接配合，主架体120还包括与板体121的下表面连接的至少一个卡勾123，各卡勾123位于板体121中与转接头122相对的端部，相应地，托板131开设有至少一个卡孔102，各卡勾123分别穿过一卡孔102并卡止于托板131的下板面。
请同时参阅图2、图4、图5和图8，进一步地，转接头122于其下表面设有插接槽103和两个卡接槽104，两个卡接槽104分置于插接槽103的两侧， 插接槽103延伸至转接头122的插接端端面，各卡接槽104延伸至转接头122的侧面，旋转连接件400插于插接槽103并与转接头122转动连接。
卡接头132于其两侧分别向相对应的卡接槽104延伸出弹性卡脚1321，旋转连接件400在第一支架100处于展开状态时与各弹性卡脚1321卡接，且第一支架100处于折叠状态时脱离各弹性卡脚1321。
在本实施例中，转接头122具有容纳槽105，该容纳槽105与转接端以及两侧相通。主架体120还包括两个连接于容纳槽105槽壁的转接板124，两个转接板124相互平行且立于容纳槽105的槽底，与此同时，两个转接板124将容纳槽105划分为上述的一个插接槽103和两个卡接槽104，其中，插接槽103位于两转接板124之间。各转接板124开设有转孔1241，旋转连接件400的各转接脚422于其自由端部开设有转接孔403，两转接脚422均插于插接槽103内，且两转接孔403与两转孔1241相通并通过转接轴依次穿设串接在一起，实现旋转连接件400与转接头122转动连接。
在本实施例中，卡接头132包括主板1322以及由主板1322两侧向上延伸出所述的弹性卡脚1321，各弹性卡脚1321的横截面皆呈S型，且其端部分别插于一卡接槽104并与相对的转接板124之间留有供弹性卡脚1321弹性变形的变形间隙，两弹性卡脚1321的自由端部的相背对两表面形成所述的卡位槽101，旋转连接件400的各限位卡脚412的卡位凸起413分别插卡于一弹性卡脚1321的卡位槽101内，这样，保持第一支架100具有展开状态。当在外力作用下，使各限位卡脚412的卡位凸起413脱离卡位槽101时，卡位凸起413沿着弹性卡脚1321的S型曲面滑移，同时，两限位卡脚412共同夹紧两弹性卡脚1321，直至两限位卡脚412抵于主板1322的下板面为止，此时，保持第一支架100具有折叠状态，当需要展开时，只需施加一定的外力，将两限位卡脚412挤开并使其沿着各弹性卡脚1321的S型曲面滑移，最终与卡位槽101卡接即可。
在本实施例中，主板1322于转接端设有U型槽106，U型槽106与插接槽103相通，避免两限位卡脚412在第一支架100处于展开状态时与主板1322发 生位置干涉。
在本实施例中，卡接头132还包括由主板1322两侧向上延伸出的固定板1323，各固定板1323于其自由端部开设有穿孔107，各固定板1323的自由端部分别插于一卡接槽104，各穿孔107分别与一转接板124的转孔1241相对且相连通，两穿孔107、两转接孔403与两转孔1241相通并通过转接轴依次穿设串接在一起，实现卡接头132的固定，也实现旋转连接件400与转接头122转动连接，同时提高转接的平稳性。
在本实施例中，主架体120还包括由各卡接槽104的槽底向下延伸成型的转接体125，固定板1323插于转接体125与转接板124之间，各转接体125于其自由端开设有通孔1251，两通孔1251、两穿孔107、两转接孔403与两转孔1241相通并通过转接轴依次穿设串接在一起，实现旋转连接件400与转接头122转动连接，更好地提高转动的平稳性。
在本实施例中，第二支架200的插接端部210于其端面向另一端面开设有两避让插槽205，各避让插槽205上下贯通，各限位卡脚412分别插于一避让插槽205。这样，更好地缩小旋转支架1的转接结构占用的空间，结构更加紧凑。
在本实施例中，旋转连接件400冲压成型。

旋转连接件400包括第一限位部410、第二限位部430以及两端分别连接第一限位部410和第二限位部430的转接部420，第一限位部410包括一端与转接部420连接的限位插板411。
将第二支架200的插接端部210于其下表面开设有延伸至插接端的限制槽202。
在步骤S01中，还包括：

S02：第一次组装。将第一支架100的转接端部110与旋转连接件400转动连接在一起。
具体地，将第一支架100的转接端部110与转接部420转动连接。
S03：第一次旋转调位。将第一支架100相对于旋转连接件400向上旋转一定角度。这样，便于安装有第一支架100的旋转连接件400顺利穿过转接口303，并安装在安装腔301。
S04：第二次组装。将装有第一支架100的旋转连接件400穿过转接口303并限位于安装腔301，同时，转接端部110也穿过转接口303并插于安装腔301内。

在本实施例中，第一步，预备旋转支架1，该旋转支架1包括第一支架100、第二支架200、固定件300和旋转连接件400；第二步，将第一支架100的转接端部110与旋转连接件400转动连接；第三步，将第一支架100相对于旋转连接件400向上旋转一定角度，便于实施接下来的步骤；第四部，将安装有第一支架100的旋转连接件400经由转接口303安装在安装腔301并限位在安装腔301，与此同时，第一支架100的转接端部110也经由转接口303插于安装腔301，转接口303是固定主体310中由第一连接端311向上侧壁开设而形成的开口，第一支架100的转接端部110可沿转接口303的延伸方向转动；第五步，将第一支架100转回固定主体310的第一连接端311，便于实施接下来的操作；第六步，将第二支架200的插接端部210穿过第二连接端312的插接口302；第七步，将第二支架200的插接端部210与固定主体310固定连接，完成安装。当第一支架100的转接端部110转至第一连接端311时，第一支架100处于展开状态；当第一支架100的转接端部110沿着转接口303转至固定主体310的上侧时，第一支架100处于折叠状态。这样，通过预备旋转支架1、第一次组装、第一次旋转调位、第二次组装、第二次旋转调位、第三次组装以及固定的步骤，完成旋转支架1的组装，经过该组装方法组装的旋转支架1，摒弃了第一支架100与第二支架200之间直接通过转接轴进行转动连接，而且通过旋转 连接件400与固定件300的加入，方便第一支架100与第二支架200的组装与拆卸。这样，一方面，组装后的旋转结构隐藏在安装腔301，不会外露，提高旋转支架1整体的美观性；另一方面，第一支架100与旋转连接件400单独组装与拆卸，不会对第一支架100和第二支架200的外形造成伤害；再有，整体结构简单，组装与拆卸简单，而且转接结构紧凑，占用空间小，提高用户对其的体验性。
