该第一头带主体210可由柔性材料制成且可任意弯曲，大体呈长条形，其可包括第一主体部2101以及从第一主体部2101一端延伸出的第一安装部2102。
第一主体部2101宽度均匀，且在远离第一安装部2102的一端开设长度调节孔2103，长度调节孔2103为条形通孔，第一主体部2101于长度调节孔2103内设置有沿通孔长度方向延伸的第一锯齿2104，以与松紧调节机构40配合。
请参阅图7，其从另一个视角揭露了本申请实施例第一头带21的立体分解图。第一主体部2101可在与第一头带盖211压紧的一侧设置有一与该第一头带21形状相同的长条形凹槽，该凹槽可以分为两个，即第一凹槽2105以及与第一凹槽2105相连的第二凹槽2106，其中该第一凹槽2105的深度与第二凹槽2106的深度相同，但第一凹槽2105的宽度较第二凹槽2106宽，该凹槽自邻近长度调节孔2103处延伸至第一安装部2102位置处。第二凹槽2106为阶梯状凹槽，其最外一阶凹槽可用于收容第一软条212。第一主体部2101在第一凹槽2105的两个侧边缘设置第一连接件2107，在一实施例中该第一连接件2107为多个均匀设置的卡勾。第一主体部2101在第一凹槽2105内设置有第一固定部2108。该第一固定部2108可为若干厚度渐变的凸肋，每一凸肋的顶面呈倾斜状，这些凸肋的一端抵顶第一安装部2102。
第一主体部2101的凹槽内设置了多个第一限位柱2109，以固定电源FPC 213、保护片214以及第一散热片215。
第一安装部2102设置有两个第一连接孔2100。在两个第一连接孔2100之间形成有凹陷2102a。
请参阅图6，第一头带盖211可由硬性材料制成，用于在第一头带主体210靠近第一安装部2102的一侧与第一头带主体210扣合，并将第一软条212靠近第一安装部2102的一端压紧。
该第一头带盖211可包括第一本体2111以及从第一本体2111远离第一软条212的一端延伸出的第一装配部2112。
该第一本体2111宽度均匀，形状与上述第一主体部2101对应，只是长度较上述第一主体部2101短。该第一本体2111在宽度方向的两个侧边缘朝向上述第一主体部2101分别延伸出第一侧壁2116，两个第一侧壁2116相对的内侧面上均设置第二连接件2117。第二连接件2117与第一连接件2107配合将第一头带盖211与第一头带主体210固定。第一本体2111可在与第一装配部2112连接的一端设置第二固定部2114，在第一头带盖211与第一头带主体210扣合时，第一头带主体210的第一固定部2108与第一头带盖211的第二固定部2114配合以将第一头带主体210和第一头带盖211之间的电源FPC 213和第一散热片215进行压紧固定；该第二固定部2114可以与第一固定部2108结构类似，其也可以为若干厚度渐变的凸肋， 每一凸肋的顶面呈倾斜状，这些凸肋的一端抵顶第一装配部2112。
第一装配部2112与第一安装部2102的形状相同，且其设置有第二连接孔2110，在第一装配部2112与第一安装部2102贴合时，第一连接孔2100与第二连接孔2110对准连通，并在凹陷2102a处形成一个贯穿孔。
第一软条212由柔性材料制成且可任意弯曲，大体呈长条形，其材料可与第一头带主体210一致，其可通过胶粘等方式黏附于第一头带主体210上的第二凹槽2106，使得第一软条212的外表面与第一头带主体210的外表面，即靠近用户头部的表面平齐。第一软条212末端设置有缺口2120，当第一软条212黏附于第二凹槽2106时，第一软条212与第一头带主体210在该缺口2120处共同形成第一穿孔，以与第二凹槽2106连通，以供电源FPC 213穿出。
同时参照图5、图6和图7，电源FPC 213形状与第一头带主体210相适配，但其长度较第一头带主体210长，两端均延伸超出第一头带主体210两端。该电源FPC 213可包括伸入第一壳体组件10内与主板80和/或麦克风组件92连接的第一电连接部2132，卡在贯穿孔内并与第一电连接部2132连接的电源FPC颈部2134，固定在第一及第二凹槽2105、2106内的电源FPC主体2136，从第一穿孔穿过置于第二凹槽2106外的活动部2137，以及设置在活动部2137端部并与电池35连接的第二电连接部2138。
请参阅图8，其为图2中圈A部分的局部放大图，其展现了该系带组件20伸入第一壳体组件10中时第一电连接部2132与电路元器件的连接示意图；其中，第一电连接部2132包括与主板80连接的接线部2132a和与麦克风组件92连接的接线部2132b；接线部2132a和第二电连接部2138均为插接口，通过插接连接。比如，如图8所示，主板80与接线部2132a插接连接，比如，如图9所示，第二电连接部2138与电池35插接连接。
再次参阅图6和图7，电源FPC颈部2134的宽度较其相邻两侧的电源FPC部分，例如电源FPC主体2136窄；以及参阅图4，可以看到电源FPC颈部2134正好卡在第一贯穿孔上，避免了电源FPC 213松动。
参阅图6至图7，电源FPC主体2136上设置了第一插孔2135，当电源FPC主体2136置于第一及第二凹槽2105、2106内时，通过将第一限位柱2109置于第一插孔2135内以将电源FPC主体2136固定。
保护片214的形状与第一及第二凹槽2105、2106相适配，以收容于该两凹槽中，比如，收容于第二凹槽2106最里一阶凹槽和第一凹槽2105内；其上设置了若干第二插孔2140，通过将第一限位柱2109置于第二插孔2140内以将保护片214固定。该保护片214容置于第一及第二凹槽2105、2106中直接与第一主体部2101接触，避免电源FPC主体2136直接与第一主体部2101接触。
第一散热片215形状与电源FPC 213相似，置于第一头带盖211与电源FPC 213之间，可包括延伸至第一壳体组件10内的第一贴合部2152，卡在贯穿孔内并与第一贴合部2152连接的第一散热片颈部2154，以及固定在第一凹槽2105以及第二凹槽2106内的第一散热片主体2156；比如，如图8所示，第一贴合部2152与扬声器本体9132侧壁贴合。
第一散热片颈部2154的宽度较其两侧的散热片部分，例如第一散热片主体2156窄；以及参阅图4，可以看到第一散热片颈部2154正好卡在贯穿孔上，避免了第一散热片215松动。第一散热片主体2156上设置了第三插孔2158，当第一散热片主体2156置于第一及第二凹槽2105、2106内时，第一限位柱2109置于第三插孔2158内以将第一散热片主体2156固定。第一固定部2108与第二固定部2114配合压置于第一头带主体210和第一头带盖211之间的第一散热片主体2156以对其进行压紧固定。
第一散热片215与第一头带盖211之间可设置填充物216。填充物216可以是泡棉，用以填充第一头带盖211与第一头带主体210之间的空间；也可以是导热材料，用以提高第一散热片215的热传导效果。
第一头带21组装时，请参阅图6和图7，首先将保护片214、电源FPC 213以及第一散热片215依次层叠，使第二插孔2140、第一插孔2135以及第三插孔2158依次对准；然后置于第一头带主体210的第一及第二凹槽2105、2106内，使第一限位柱2109依次穿过第二插孔2140、第一插孔2135以及第三插孔2158；再将第一软条212嵌入覆盖在第二凹槽2106最外一阶凹槽上，可以通过胶水粘接，使得第一软条212在缺口2120处与第一头带主体210的第一主体部2101形成第一穿孔，进而使电源FPC 213的活动部2137从第一穿孔穿过，同时电源FPC 213的电源FPC颈部2134以及第一散热片颈部2154置于凹陷2102a内部；接着将填充物216置于第一头带盖211的第一本体2111上，然后将第一头带盖211扣合在第一头带主体210上使得第一连接件2107和第二连接件2117连接，同时第一安装部2102与第一装配部2112扣合也形成了连接部，以与第一壳体组件10的对应端相连接；至此完成第一头带21组装。
可以理解的，第一头带盖211扣合在第一头带主体210上，与第一头带主体210对应的部分共同形成容纳空腔，而且是第一主体部2101于第一凹槽2105位置处与第一头带盖211扣合形成容纳空腔；在容纳空腔内可容置保护片214、电源FPC 213、第一散热片215以及填充物216；第二凹槽2106与容纳空腔相通。
系带组件20的第二头带22
请参阅图10和图11，其揭露了本申请实施例第二头带22的立体组装图和分解图。第二头带22与第 一头带21类似，二者的不同点在于第二头带22没有设置电源FPC及其保护片。第二头带22可包括第二头带主体220，第二头带盖221及压置于第二头带主体220和第二头带盖221之间的第二软条222以及第二散热片225。第二头带主体220的构造与第一头带主体210的构造大致相同，具体请参图11，在此不做详细阐述，仅将其主要元件罗列出来，具体配合关系以及功能参考第一头带主体210的介绍。该第二头带主体220可包括第二主体部2201以及第二安装部2202。第二主体部2201具有长度调节孔2203、第二锯齿2204、第一凹槽2205以及第二凹槽2206，第一凹槽2205两侧设置有第一连接件2207，第一凹槽2205邻近第二安装部2202处设置有第一固定部2208。第二安装部2202上设有两个第一连接孔2200，并在两个第一连接孔2200之间形成有凹陷2202a。
请参阅图12，其从另一个视角揭露了本申请实施例第二头带22的立体分解图；其中第二头带盖221与第一头带盖211的构造大致相同，在此不做详细阐述，仅将其主要元件罗列出来，具体配合关系以及功能参考第一头带盖211的介绍。该第二头带盖221可包括第二本体2211和第二装配部2212。第二本体2211具有第二固定部2214、第二侧壁2216以及第二连接件2217。第二装配部2212设置有两个第二连接孔2210。
第二软条222由柔性材料制成且可任意弯曲，大体呈长条形，其材料可与第二头带主体220一致，其可通过胶粘等方式黏附于第二头带主体220上的第二凹槽2206内，使得第二软条222的外表面与第二头带主体220的外表面，即靠近用户头部的表面平齐。
第二散热片225与第一散热片215的构造大致相同，可包括延伸至第一壳体组件10内第二贴合部2252、卡在贯穿孔内并与第二贴合部2252连接的第二散热片颈部2254，以及固定在第一及第二凹槽2205、2206内的第二散热片主体2256；参阅图13所示，第二贴合部2252与扬声器组件91的扬声器本体9132侧壁贴合。

当第二散热片主体2256置于第一及第二凹槽2205、2206内时，第一固定部2208与第二固定部2214配合对置于第二头带主体220和第二头带盖221之间的第二散热片主体2256进行固定。
第二头带盖221在设置第二连接件2217区域内设置填充物226，填充物226置于第二散热片225与第二头带盖221之间。该填充物226可以是泡棉，用以填充第二头带盖221与第二头带主体220之间的空间；也可以是导热材料，用以提高第二散热片225的热传导效果。
第二头带22组装时，请参阅附图11至图12，首先将第二散热片225置于第二头带主体220内的第一凹槽2205和第二凹槽2206内，然后将第二软条222嵌入覆盖在第二凹槽2206最外一阶凹槽上，可以通过胶水粘接；然后将第二散热片颈部2254置于凹陷2202a内；此时将第二填充物226置于第二头带盖221上，然后将第二头带盖221扣合在第二头带主体220上使得第一连接件2207和第二连接件2217连接，同时第二安装部2202与第二装配部2212扣合也形成了连接部，以与第一壳体组件10的对应端相连接；至此完成第二头带22组装。
可以理解的，第二头带盖221扣合在第二头带主体220上，与第二头带主体220对应的部分共同形成容纳空腔，而且是第二主体部2201于第一凹槽2205位置处与第二头带盖221扣合形成容纳空腔；在容纳空腔内可容置第二散热片225以及填充物226；第二凹槽2206与容纳空腔相通。
对于系带组件20与第一壳体组件10的组装关系，具体介绍如下：
参阅图1、图5、图6、图7和图4，第一头带21组装至第一壳体组件10的时候，首先将第一壳体组件10与第一头带21上连接部连接，比如与第一及第二连接孔2100、2110连接。同理，也可将第二头带22组装至第一壳体组件10。
对于第一散热片215、第二散热片225、电源FPC 213在第一壳体组件10内部的位置关系及连接关系可以参阅图2、图3、图8和图13；电源FPC 213的接线部2132a与主板80上的PCB连接，比如焊接等；电源FPC 213的接线部2132b与麦克风组件92中的第一麦克风连接，比如焊接等；第一散热片215延伸到第一壳体组件10内，其第一贴合部2152与扬声器组件91的扬声器本体9112外侧壁贴合。第二散热片225延伸至第一壳体组件10内，其第二贴合部2252与扬声器组件91的扬声器本体9132外侧壁贴合。
对于第一头带21和第二头带22内部填充的散热片、电源FPC 213、保护片214和填充物也是可以根据实际情况来做数量、结构、位置的调整，比如可以把第一头带21和第二头带22均调整为内部填充散热片、电源FPC 213、保护片214和填充物；当然也可以根据实际情况再填充其他结构或删减部分已有结构，比如在散热片和电源FPC之间填充隔离片，比如可以把第一头带21和第二头带22均调整为内部仅填充散热片，比如第一头带21和第二头带22两者中的一个可以为仅具有长度调节孔的普通头带；而第一头带21和第二头带22的结构也会根据内部填充的不同做适应性调整。
可以理解地，第一头带21和第二头带22也可以是一体地，即作为一个头带来使用；比如，其一端与另一端交叠连接，其中部可以与主机壳体连接，通过调节交叠连接部分的长度来完成系带组件20地松紧调节；在第一头带21和第二头带22作为一个头带来使用，也可以采用其他连接方式，在此并不做限定。

第一及第二凸沿3211、3212两相对外侧设置第一卡扣件3216，该第一卡扣件3216可为若干均匀排列的凹槽，以便与第一通道壳311的第一卡扣件3116，即若干凸起相互配合，从而将第一通道壳311与第二通道壳321卡合在一起以形成供系带组件20穿过的通道。
第一凸沿3211上与底前壳31的第一凸沿3111上凹槽3118对应的位置处朝向底前壳31设置有卡勾3217，以用于与松紧调节机构40的相关元件扣合，其中底前壳31上对应的凹槽3118在卡勾3217与松紧调节机构40的相关元件扣合过程中起避让作用。
第二电源壳322包括自第二通道壳321的本体3210中部向外凹陷并向下延伸设置的第二电源壳本体3220、自该第二电源壳本体3220边缘向底前壳31弯折延伸设置的侧壁3221、位于第二电源壳322内的一分隔板3222以及位于该分隔板3222下方且安装于第二电源壳322内的电源支架324。

底前壳31和底后壳32扣合后，第一通道壳311的本体3110和第二通道壳321的本体3210形成供系带组件20伸入的通道；第一电源壳312和第二电源壳322配合后，位于分隔板3222上方的空间可定义为第一收容腔，位于分隔板3222下方的空间可定义为第二收容腔；第一收容腔与通道连通，二者可共同定义为第一通道；第一收容腔除收容可相互交叠的第一头带21和第二头带22之外，还可以收容松紧调节机构40，以调节第一头带21和第二头带22交叠部分的长短，因此构成通道和第一收容腔的实体部分也可以定义为头带及松紧调节机构壳体(也可以定义为第一壳体)；第二收容腔用于收容电源，例如电池35，可定义为电源壳体(也可以定义为第二壳体)。
可以理解地，底前壳31和底后壳32扣合后，第一电源壳312、第二电源壳322与第一通道壳311的本体3110可定义为第一壳体；而位于第一壳体两侧的第一通道壳311和第二通道壳321可定义为第二壳体。
上述各种名称，例如：通道，收容腔，第一收容腔，第二收容腔，第一壳体，第二壳体，头带及松紧调节机构壳体，电源壳体，可根据实际情况进行调整，本申请并不限于对上述名称的限定，根据实际情况同类结构的名称可以进行互换，例如，通道也可称作第一收容腔，此时原第一收容腔可称作第二收容腔，原第二收容腔可称作第三收容腔，第一壳体和第二壳体的名称也可互换。
松紧调节机构40

对于安装件也不仅限于第一挡板421和第二挡板422组装的形式，其它可以使得第一棘爪424和第二棘爪425与棘轮414接触配合即可；即安装件留有缺口或类似缺口的结构以供第一棘爪424和第二棘爪425伸出安装件所形成的空间与棘轮414接触配合；所以安装件也可以是一个留有缺口或类似缺口的盒体；
当然安装件也可以仅是第一挡板421或第二挡板422，比如安装件为第二挡板422，第二卡接部4224和第二连接部4214作为限位部形成于第一挡板421或第二挡板422上。
第一安装轴4225和第二安装轴4226分别位于第一卡接部4222两侧，且相对于第一卡接部4222对称设置。

需要指出的是，第一弹簧426和第二弹簧427也可以是其他弹性件，比如拉簧、压簧、提供伸缩力的物体等，以使得第一棘爪424、第二棘爪425与棘轮414配合完成卡合和非卡合两个状态的转换；而相应的第一安装框4227和第二安装框4228也会根据弹性件的不同而改变为其他可以固定弹性件的结构。
转板423为一偏心轮结构，其具有一贯穿孔4230，当然转板423也可以和旋钮组件430在贯穿孔4230处为一整体；该贯穿孔4230与第二挡板422的中心孔4220对齐且具有相同的轴线。在其中一实施例中，该贯穿孔4230的内表面呈多边形，例如六边形。转板423远离贯穿孔4230的一端具有一缺口4232，缺口4232的形状与第二挡板422的第一卡接部4222形状相同，只是大小不同，其大小较第一卡接部4222的尺寸大，以将第一卡接部4222收容进来。在这里，第二卡接部4224和第二连接部4214作为限位部以与缺口4232配合；缺口4232具有两个相对的内壁，为第一内壁4232a以及与第一内壁4232a相对设置的第二内壁4232b；转板423的周面包括一外壁面4234。在转板423绕贯穿孔4230的轴线转动时，转板423与第二卡接部4224仅有三种状态：仅有第一内壁4232a与第一卡壁4220a接触的状态，转板423与第二卡接部4224无接触状态，以及仅有第二内壁4232b与第二卡壁4220b接触的状态；即限位部被配置为与缺口4232的内壁面接触和不接触两种状态以使得转板423绕其转动轴(贯穿孔4230的轴心)转动一定角度。
请同时参阅图24到图26，第一棘爪424枢接安装于第二挡板422的第一安装轴4225上并可绕着该第一安装轴4225转动。第一棘爪424中间位置处设有一枢接孔4240以枢接至第一安装轴4225上。第一棘爪424具有两个相对端，即：与第一弹簧426连接的第一端4242以及与转板423的外壁4234抵接的第二端4244。该第一端4242朝向第一安装框4227的收容空间4227d的一侧设有一安装轴4242a，以将第一弹簧426套设安装于其上，该第一端4242背离第一安装框4227的一侧具有一棱角4242b，该棱角4242b用于与棘轮414的内齿4140卡合(请参阅图27所示)。该第二端4244朝向转板423的一侧具有一接触面4244a， 在一实施例中，该接触面4244a为弧面，以与转板423的外壁面4234呈线性接触，以减小二者之间的压力。
第二棘爪425与第一棘爪424相对于第二挡板422的第一卡接部4222对称设置，二者具有完全相同的形状构造，在此不再赘述，仅将其元件罗列出来。第二棘爪425具有枢接孔4250、第一端4252、第二端4254、安装轴4252a、棱角4252b、接触面4254a。
第一弹簧426安装时，一端套设于第一安装框4227内的卡轴4227e上，另一端套设于第一棘爪424的安装轴4242a上，如此第一弹簧426便安装于第一安装框4227内，第一棘爪424可绕着第一安装轴4225转动，当第一棘爪424转动时进而带动第一棘爪424的第一端4242运动，从而推动第一弹簧426于第一安装框4227内做不同程度的压缩。
第二弹簧427的构造和功能与第一弹簧426完全相同，其安装于第二安装框4228中，在此不再赘述。
转板423的外壁面4234为曲面，外壁面4234被配置为：当转板423绕其转动轴转动时，外壁面4234分别推动第一及第二棘爪424、425旋转，使第一及第二棘爪424、425与棘轮414完成卡合和非卡合两个状态的转换。请参阅图25，在无外力施加迫使转板423或安装件(第一挡板421和第二挡板422的结合体)转动时；由于第一弹簧426和第二弹簧427的作用，使得转板423与限位部外表面(即第二卡接部4224的外表面)处于无接触状态时，且棘爪组件420与棘轮414进行卡合状态；在外力介入下迫使转板423绕贯穿孔4230的轴线转动时，出现两种状态：
(1)由无接触状态转变为仅有第一内壁4232a与第一卡壁4220a接触的状态，此时，在转板423绕贯穿孔4230转动的方向上，第一棘爪424与外壁面4234的接触位置到贯穿孔4230的距离逐渐增大，以使第一棘爪424的第一端4242运动，并与棘轮414内壁的内齿4140脱离卡合状态；而第二棘爪425与外壁面4234的接触位置到贯穿孔4230的距离逐渐减小，但棘轮414对第二棘爪425的第二弹簧427进行挤压，使得第二棘爪425与棘轮414内壁的内齿4140也处于脱离卡合状态；最终棘爪组件420与棘轮414脱离卡合状态。
(2)由无接触状态转变为仅有第二内壁4232b与第二卡壁4220b接触的状态，此时，在转板423绕贯穿孔4230转动的方向上，第二棘爪425与外壁面4234的接触位置到贯穿孔4230的距离逐渐增大，以使第二棘爪425的第二端4254运动，并与棘轮414内壁的内齿4140脱离卡合状态；第一棘爪424与外壁面4234的接触位置到贯穿孔4230的距离逐渐减小，但棘轮414对第一棘爪424的第一弹簧426进行挤压，使得第一棘爪424与棘轮414内壁的内齿4140也处于脱离卡合锁紧状态；最终棘爪组件420与棘轮414脱离卡合状态。
请参阅图23，齿轮428具有一中心孔4280，该中心孔4280与第二挡板422的中心孔4220对齐且中心轴线相同。该齿轮428固定设置于第二挡板422远离第一挡板421的一侧。
同时参阅图28，在系带组件20与松紧调节机构40连接时，第一头带21设置长度调节孔2103的一端与第二头带22设置长度调节孔2203的一端层叠，此时第一锯齿2104和第二锯齿2204分别位于二层叠长度调节孔2103、2203内的相对两侧，齿轮428则置于层叠的二长度调节孔2103、2203内且与第一锯齿2104以及第二锯齿2204进行啮合。
请参阅图29及图30，旋钮组件430可包括旋转盘431、自旋转盘431内表面延伸设置的第一传动轴432以及安装于第一传动轴432上的第二传动轴433。
旋转盘431的侧表面可为粗糙的结构，在其中一实施例中，旋转盘431外表面设置有若干平行排列的凹槽，以在两个相邻凹槽间形成凸肋。
第一传动轴432与第二挡板422具有相同的中心轴线，第一转动轴432沿朝向第二挡板422的中心轴线方向依次形成有同轴设置的第一连接轴4321、第二连接轴4322以及第三连接轴4323。第一连接轴4321与第二连接轴4322均为圆轴，即外周面为圆形且第一连接轴4321的外径较第二连接轴4322的外径大。第三连接轴4323的外周面为多边形，在一个实施例中为六边形，六边形的中心距离六边形任意一条边的距离小于第二连接轴4322的半径，第三连接轴4323的中心处设有一中心孔4324，该中心孔4324具有内螺纹。
第二传动轴433与第一传动轴432具有相同的中心轴线，其沿朝向远离旋转盘431的轴线方向依次形成有同轴设置的圆盘4330、与圆盘4330连接的第一连接轴4331、与第一连接轴4331连接的第二连接轴4332以及与第二连接轴4332连接的第三连接轴4333。
圆盘4330的外径大于第一连接轴4331的外径，且大于齿轮428的外径，其底部设有一凹陷4330a，凹陷4330a的中间位置处设有一通孔4330b。该凹陷4330a的内壁呈多边形，在其中一个实施例中为六边形，以与第一传动轴432的第三连接轴4323配合；在齿轮428置于层叠的第一及第二头带21、22的二长度调节孔2103、2203内时，圆盘4330与齿轮428以及第二挡板422配合，对第一及第二头带21、22进行限位，避免第一及第二头带21、22脱离与齿轮428的啮合状态。
第一连接轴4331与第三连接轴4333均为圆轴，即外周面为圆形且第一连接轴4331的外径较第三连 接轴4333的外径大。第二连接轴4332的外周面为多边形，在一个实施例中为六边形，中心距离六边形任意一条边的距离小于第一连接轴4331的半径大于第三连接轴4333的半径。该第二连接轴4332的形状尺寸与转板423的贯穿孔4230的形状尺寸相匹配，从而将转板423固定连接至该第二连接轴4332上。
在对系带组件20、第二壳体组件30、松紧调节机构40进行组装时，先将系带组件20组装好，将系带组件20的第一头带21和第二头带22分别穿过一个连接件33的通孔3310，同时，将旋转盘431的第一传动轴432从底后壳32的后边穿过穿孔凸台3220a，再将圆盘4330安装于第三连接轴4323上；从而将第二传动轴433与第一传动轴432卡合，接着将螺丝434穿过圆盘4330底部的通孔4330b并与第一传动轴432的第三连接轴4323的中心孔4324螺纹连接，从而将第二传动轴433与第一传动轴432稳固地连接在一起。
将第一头带21的长度调节孔2103所在部位和第二头带22的长度调节孔2203所在部位重叠，接着将齿轮428置于长度调节孔2103与长度调节孔2203内，将第二传动轴433穿过齿轮428与中心孔4210、第二挡板422的中心孔4220，在第二挡板422上安装第一棘爪424、第二棘爪425、第一弹簧426、第二弹簧427和转板423，比如，将转板423穿过第二传动轴433的第三连接轴4333进而套设于第二连接轴4332上使转板423相对第一及第二转动轴432、433固定设置，同时使第二挡板422上的第二卡接部4224位于转板423的缺口4232内；第一棘爪424以及第二棘爪425的第二端4242、4252与转板423的外壁面4234接触。
然后将第一挡板421扣合在第二挡板422，第一挡板421上的第一连接部4212与第二挡板422上的第一卡接部4222相卡合，如此便将第一挡板421组装于第二传动轴433上，同时使第一挡板421相对于第二挡板422固定设置，也就是说第一挡板421可以与第二挡板422一同相对于第二传动轴433作径向转动；将第一棘爪424、第二棘爪425、第一弹簧426、第二弹簧427和转板423固定在第一挡板421和第二挡板422之间；将棘爪组件420收容于棘轮414内，并将第二传动轴433的第三连接轴4333伸入棘轮414内的中心孔4100使二者配合；然后将第一壳体41与底后壳32进行扣合；此时，齿轮428底部抵靠圆盘4330，圆盘4330对第一头带21、第二头带22进行挤压限位(请参阅附图31)；第一扣合结构4120的凸块置于承载肋3228b上支撑第一壳体41；第二扣合结构4122与底后壳32上卡勾3217进行卡固，第一安装部413用螺丝与底后壳32固定；以此将第一头带21和第二头带22固定在了松紧调节机构40内部，至此，也完成了系带组件20与松紧调节机构40组装。
将电源支架324上的扣合部3245扣合在承载部3228上对应的开口3228a；将电源支架324上的扣合结构3246扣合在侧壁3221上对应的扣合结构3224；接着在电源支架324上铺设电池垫片3243，放置电池35；对底前壳31和底后壳32进行组装；将底后壳32上的第一卡扣件3216扣合在第一通道壳311上对应的第一卡扣件3116；将底后壳32上的第二卡扣件3223扣合在凸沿3121上对应的第二卡扣件3123；随后将两个连接件33安装，将连接件33的卡扣件3313扣合在底前壳31的第三卡扣件3113以及底后壳32的第三卡扣件3213上，对底前壳31和底后壳32进行了固定，至此完成了系带组件20与第二壳体组件30、松紧调节机构40的组装。
在对系带组件20进行调节时，参阅图25，在初始状态，第一弹簧426对第一棘爪424顶起，使得第一端4242与棘轮414的内齿4140卡合，第二弹簧427对第二棘爪425顶起，使得第一端4252与棘轮414的内齿4140卡合；此时第一棘爪424和第二棘爪425与转板423接触，使得转板423与第二卡接部4224处于无接触状态；系带组件20对安装件作用使得安装件向任意一个方向转动时，均有一个棘爪与棘轮414的内齿4140卡合；使得安装件的限位部无法与转板423直接接触；迫使第一挡板421无法完成转动，进而对头带组件20进行卡合，避免系带组件20的松动；
在利用旋钮组件430对系带组件20的长度进行调节时，旋钮组件430带动转板423进行转动，使得由转板423与第二卡接部4224的无接触状态转变为仅有第一内壁4232a与第一卡壁4220a接触的状态或仅有第二内壁4232b与第二卡壁4220b接触的状态，这两种状态都会导致棘爪组件420与棘轮414脱离卡合状态，进而带动第一挡板421转动，通过齿轮428使得系带组件20的松紧进行了调节。
可以理解地，第一壳体41也可以为第二壳体组件30中的底前壳31，而棘轮414可以形成于本体3110上，同时中心孔4100也形成于本体3110上，棘轮棘爪机构42与棘轮414配合；另外，当第一及第二头带21、22交叠连接至松紧调节机构40，并在松紧调节机构40调节第一及第二头带21、22相互交叠的长度时，第一及第二头带盖211、221至松紧调节机构40以及至头带及松紧调节机构壳体的距离也会随之调节；在这里底前壳31和底后壳32可以形成松紧调节机构壳体作为松紧调节机构的一部分，当然也可以是第一壳体41和底后壳32形成松紧调节机构壳体。
受力组件50
请参阅附图1，其揭露了一实施例中头戴式设备100的立体结构示意图，其中，受力组件50包括设置在第一壳体组件10上的第一受力件51和设置在第二壳体组件30上的第二受力件52。在此实施例中，第一壳体组件10、系带组件20、第二壳体组件30和松紧调节机构40可构成一松紧可调的环形框架，并且 第一受力件51和第二受力件52分别位于该环形框架的一侧和另一侧，例如分别位于第一壳体组件10与第二壳体组件30的上下两侧。第一受力件51向靠近第二受力件52的一侧倾斜；另外，第一受力件51为第一受力点，第一壳体组件10为第二受力点，第二受力件52为第三受力点，头戴式设备100通过第一、第二和第三受力点进行稳固支撑、佩戴。
可以理解的是，“第一受力件”和“第二受力件”也可以分别被称为“受力件”。
受力组件50的第一受力件51
请参阅图2，第一受力件51可包括支撑板511、与支撑板511大致呈一角度设置且安装在第一壳体组件10上的安装板512、位于支撑板511与安装板512之间且连接二者的颈部513以及设置于支撑板511上的软垫514。
受力组件50的第二受力件52
请参阅附图32，其揭露了一实施例中受力组件50的第二受力件52与第二壳体组件30中底前壳31的分解图；第二受力件52固定安装于第二壳体组件30的底前壳31上；请参阅附图33，其揭露了一实施例中第二受力件52的立体分解图以及立体组装图，第二受力件52可包括一固定板521以及包覆到该固定板521上的软垫522。
该固定板521的形状与第二壳体组件30的底前壳31的第一电源壳本体3120的形状大小相匹配，其上设置有与第一电源本体3120上的连接件3126对应的安装孔5210。
将第二受力件52安装于第二壳体组件30时，首先将软垫522套设于固定板521上，然后将固定板521对准第一电源本体3120上的连接件3126，使连接件3126紧固地插入安装孔5210上，从而将第二受力件52稳固安装于第二壳体组件30上；可选择地，连接件3126和安装孔5210的位置可相互变换，即安装孔5210设置在第二壳体组件30上，连接件3126设置在第二受力件52上。当然，本申请并不限于安装孔5210和连接件3126的形式，任何可以让第二受力件52安装于第二壳体组件30上的方式均可使用，比如，胶粘接。
在用户进行佩戴头戴式设备100时，由于系带组件20将第一壳体组件10和第二壳体组件30连接在一起，并形成一个可佩戴的环形框架，而且使得第二受力件52、第一壳体组件10为主要受力点，第一壳体组件10与用户的前额进行接触，第二受力件52与用户的后脑勺进行接触，用户通过前额、后脑勺对头戴式设备100进行支撑；由于第一受力件51在前额上方向第二受力件52处倾斜设置，并与用户前额上方的部位进行接触，所以可以来稳固支撑头戴式设备100，因此使得用户佩戴更加舒服。
以上所述是本申请的优选实施例，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
