第一挡板421与第二挡板422也可以作为一个安装件使用,第二卡接部4224和第二连接部4214可以作为限位部与转板423配合,也可以作为固定部以将第一挡板421和第二挡板422固定在一起;第一卡接部4222和第一连接部4212作为固定部以将第一挡板421和第二挡板422固定在一起。
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。

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也可以和传动齿轮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23到图25,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26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24,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22,配合齿轮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。该配合齿轮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27,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,配合齿轮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28,传动齿轮430可包括齿轮转盘431、自齿轮转盘431内表面设置的转动轴433,转动轴433沿朝向远离齿轮转盘431的轴线方向依次形成有同轴设置的与齿轮转盘431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。
在配合齿轮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,齿轮转盘431与配合齿轮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脱离与配合齿轮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。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,接着将配合齿轮428置于长度调节孔2103与长度调节孔2203内,将第二传动轴433穿过配合齿轮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相对第二转动轴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,配合齿轮428底部抵靠齿轮转盘431,齿轮转盘431对第一头带21、第二头带22进行挤压限位(请参阅附图29);将侧板412与底后壳32扣合固定以将第一头带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。
放置电池35后对底前壳31和底后壳32进行组装;随后将两个连接件33安装,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26,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。
在对系带组件20的长度进行调节时,传动齿轮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,从而使配合齿轮428转动,进而使得第一头带21和第二头带22做反向运动,使得系带组件20的整体长度发生变化,从而对系带组件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可以形成于第一通道壳311的本体上,同时中心孔4100也形成于第一通道壳311的本体上,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。
如图30所示,图30为松紧调节机构中的驱动组件与传动齿轮的装配结构示意图。驱动组件44可以包括电机和变速箱。其中,电机可以是步进电机,变速箱的输入端与步进电机的输出轴连接,变速箱的输出端齿轮与传动齿轮430啮合,从而通过电机带动传动齿轮430转动。传动齿轮430的转动能带动棘爪组件420转动,从而使配合齿轮428转动,以带动第一头带21和第二头带22相对运动。
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。
请参阅图31及图32,其揭露了一实施例中第一受力件51两个不同视角的立体图。其中,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。
该支撑板511可为四边形板体,其远离第二壳体组件30和软垫514的一面为曲面。该支撑板511安装软垫514的一面可为凹形曲面,以大致匹配用户额头或额头上方部位的轮廓。该支撑板511自安装板512的一侧延伸设置,并且向安装软垫514的一侧倾斜,使得安装板512与支撑板511呈钝角设置。颈部513可与支撑板511具有相同的延伸方向,就是也自安装板512的一侧延伸,从而使得颈部513 与安装板512呈钝角设置;颈部513也可自安装板512向上弯折,使得颈部513与安装板512呈直角或锐角设置。
该安装板512为具有厚度的板状结构,其用硬性材料制成,其用于与主前壳10的顶板111以及主壳装饰件15配合安装,例如夹设在顶板111和主壳装饰件15之间。该颈部513用硬性材料制成。该软垫514对应于该支撑板511的形状,且固定在该支撑板511朝向第二壳体组件30一侧。软垫514和安装板512分别在支撑板511的相对两侧。
请参阅附图33,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34至图35,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31的形状大小相匹配。第二受力件52可以通过卡扣的方式固定在第二壳体组件30上,也可以通过胶水粘接在第二壳体组件30上。
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。
第一传感器设置在第二受力件52上,用于检测软垫522的变形参数值。其中,软垫522的变形参数可以包括软垫522的厚度、软垫522的密度、软垫522的透光率或其它变形参数。
本实施例的软垫的参数为软垫522的厚度。举例而言,如图34所示,第一传感器可以包括第一传感器件941和第一磁体942,其中,第一传感器件941可以是霍尔开关,其通过检测第一磁体942产生的磁场来确定软垫522的厚度。具体地,第一磁体942可以设置在软垫522远离固定板521的一侧(如图1和图6所示),霍尔开关则可以设置在固定板521靠近软垫522的一侧。一些实施例中,第一磁体942还可以设置在软垫522内部,使得软垫与人体接触的表面保持柔软舒适,而不受霍尔开关的影响。在这种情况下,第一传感器检测的是第一磁体942与霍尔开关之间的部分软垫的厚度。可以理解地,在其它一些实施例中,该第一磁体942还可以设置在固定板521上,霍尔开关则可以设置在软垫522上。一些实施例中,霍尔开关包括集成在一个芯片上的霍尔元件、放大器电路、温度补偿电路及稳压电源电路。霍尔元件通常由半导体薄片制成,具有对磁场敏感、结构简单、体积小、频率响应宽、输出电压变化大和使用寿命长等优点。在霍尔元件薄片的两端通以控制电流I,并通过磁体在薄片的垂直方向施加磁感应强度为B的匀强磁场,则在垂直于电流和磁场的方向上,将产生电势差,即霍尔电压UH的霍尔电压,它们之间的关系为UH=k IB/d,其中,d为薄片的厚度,k为霍尔系数,其与大小和薄片的材料有关。k、d、I不变的情况下,UH随B变化,而B则与霍尔元件与磁体之间的距离(本实施例中即,软垫的厚度)有关。因此,可以根据霍尔开关检测出的霍尔电压来确定软垫的厚度。
具体地,当第一传感器检测到的软垫522的变形参数值达到预设阈值时,松紧调节机构40停止调节系带组件20的长度。例如,软垫522在自然状态下的厚度为1cm,软垫522的厚度的预设阈值为0.5cm,当第一传感器检测到的软垫522的厚度减小到或者小于0.5cm时,松紧调节机构40则停止调节系带组件20的长度。举例而言,当用户佩戴上该头戴设备100后,减小系带组件20的长度直至头戴设备100能稳定绑在用户头部,获取此时软垫522的厚度,并将该厚度作为预设阈值。当然,在其它一些实施例中,也可以在将头戴设备100能稳定绑在用户头部,并且用户对关于头戴设备100的系带组件20的松紧度感受较舒适之时的软垫522的厚度设置为预设范围阈值。
第二传感器用于检测系带组件20的伸缩长度,例如,检测系带组件20是否伸长到第一状态,或者是否缩短到第二状态。请参阅附图17和图27,第二传感器包括第二磁体951、第二传感器件952和第三传感器件953,其中,第二传感器件952和第三传感器件953可以是霍尔元件。具体地,第二磁体951固定在第二头带22上,第二传感器件952设置在第二壳体组件30的第二通道壳321上,当系带组件20伸长到第一状态时,即,第一头带21和第二头带22的重叠长度最短时,第二传感器件952对应第二磁体951。第三传感器件953设置在第二壳体组件30的第二通道壳321上,当系带组件20缩短到第二状态时,即,第一头带21和第二头带22的重叠长度最长时,第三传感器件953对应第二磁体951。
在一些实施例中,当系带组件20伸长到第一状态或缩短到第二状态时,第二磁体951均位于第二通道壳321内,第二传感器952和第三传感器953均设置在第二壳体组件30的第二通道壳321的内壁上。
当系带组件20的伸缩长度到达第一状态,松紧调节机构40停止调整系带组件20的长度。当系带组件20的伸缩长度到达第二状态,松紧调节机构40停止调整系带组件20的长度。本申请通过设置第 二传感器检测系带组件20是否伸长到最长或是否缩短到最短,在系带组件20伸长到最长状态或缩短到最短状态时,松紧调节机构40停止调整系带组件20的长度,从而防止转堵。
控制开关与松紧调节机构40连接。用户可以通过触发控制开关来启动松紧调节机构40对系带组件20的长度的调整。例如,当用户开启控制开关使控制开关处于第一控制状态时,松紧调节机构40对系带组件20进行伸长调节。当用户开启控制开关使其处于第二控制状态时,松紧调节机构40对系带组件20进行收缩调节。
至少上述实施例中的第二受力件52、第一传感器和松紧调节机构40可以定义为松紧调节装置,用于调节系带组件20的整体长度。
在一些实施例中,控制开关可以是头戴设备100的开机键,例如,当用户按下开机键指示开启头戴设备100的同时,松紧调节机构40对系带组件20进行伸长调节。当然,控制开关也可以是头戴设备100的音量键等,例如,可以通过短按音量键来调整头戴设备100的音量,通过长按音量键来启动系带组件20的长度的调整。本申请通过共用按键来简化头戴设备100的结构。
值得一提的是,在一些实施例中,用户还可以在头戴设备稳定佩戴在头部之后,对系带组件20进行微调,以满足用户对佩戴舒适的要求。举例而言,当用户佩戴头戴设备之处,驱动组件44中的步进电机以整部步距角进行转动来缩短系带组件22。当软垫522的厚度减小达到预设阈值时,步进电机停止转动。此时,用户若再启动微调开关,或者将控制开关调整到第三状态,则步进电机可以以半步步距角进行转动来缩短或增长系带组件20,从而实现微调,直至用户关闭微调开关。通过该方式可以使系带组件20的长度不仅能使头戴设备稳定佩戴在用户头部,还能使用户感觉舒适,从而使该头戴设备能适用于不同头型或不用体验要求的用户。
本申请还提供了一种系带调节装置,用于调节穿戴设备的系带的长度。具体地,该系带调节装置可以包括与系带连接的挤压件、设置在挤压件上的第一传感器和与系带配合连接的松紧调节机构。具体地,挤压件可以包括支撑板和软垫,支撑板可以直接与系带连接。其中,系带可以是上述实施例中的系带组件,第一传感器和松紧调节机构的结构可以如上述实施例所描述,在此不再赘述。值得一提的是,支撑板和系带之间的连接可以是直接连接或间接连接,例如,支撑板直接粘合在系带上,或者支撑板的两端分别与系带连接,或者,还可以如上述实施例所描述的,支撑板固定在第二壳体组件30上,而系带则与第二壳体组件30内的松紧调节机构配合连接,从而实现支撑板与系带的间接连接。
如上述实施例所描述,该挤压件可以是上述实施例中的第二受力件52。在其它一些实施例中,挤压件还可以是第一受力件51,在这种情况下,挤压件的支撑板即第一受力件51的支撑板511,挤压件的软垫则为第一受力件51的软垫514。在另一些实施例中,可以通过在主机壳体10上设置软垫而形成挤压件,在这种情况下,主机壳体10相当于挤压件的支撑板。在另一些实施例中,可以在第二壳体组件30上设置软垫而形成挤压件,在这种情况下,第二壳体组件30相当于挤压件的支撑板。
本申请的另一方面还提供了一种系带调节装置,用于调节穿戴设备的系带的长度。具体地,该系带调节装置可以包括连接于系带的壳体;设置在壳体上的软垫;设置在壳体或软垫至少之一上的第一传感器,该第一传感器用于检测软垫的变形参数值;与系带配合连接的松紧调节机构,用于调节系带的长度;以及响应于第一传感器检测到的软垫的变形参数值而控制松紧调节结构调节系带的长度的处理器。
具体地,系带可以是上述实施例中的系带组件20,壳体可以是上述实施例中的主机壳体10、第二壳体组件30或者其它与系带组件20连接的壳体。软垫、第一传感器以及松紧调节机构的结构可以与上述任一实施例所描述的相同,在此不再赘述。
处理器响应于软垫的变形参数值到达预设阈值而控制松紧调节装置停止调节系带的长度。
在一些实施例中,系带调节装置还可以包括与处理器连接的第二传感器,用于检测系带的伸缩长度是否处于第一状态或第二状态。处理器响应于系带的伸缩长度处于第一状态或第二状态而控制所述松紧调节装置停止调节所述系带。
如图36所示,第一传感器94、第二传感器95和松紧调节机构40均连接于处理器96。第一传感器94将检测的软垫的变形参数值的信息发送给处理器96,当软垫的变形参数值到达预设阈值时,处理器96控制松紧调节机构40停止调节系带组件20的长度。第二传感器95将检测的系带组件20的伸缩长度的状态信息发送给处理器96,当系带组件的伸缩长度处于伸长到最长的状态或收缩到最短的状态时,处理器96控制松紧调节机构40停止调节系带组件20的长度。
在一些实施例中,系带调节装置还可以包括控制开关,该控制开关与处理器连接。处理器响应于控制开关处于第一控制状态而控制所述松紧调节装置对所述系带进行伸长调节;以及处理器响应于控制开关处于第二控制状态而控制松紧调节装置对系带进行收缩调节。
在一些实施例中,如图37所示,处理器96可以包括MCU961和逻辑电路962。控制开关97与MCU961连接,第一传感器94可以包括第一传感器件941和第一磁体,第二传感器95包括第二磁体、 第二传感器件952和第三传感器件953。第一传感器件941、第二传感器件952和第三传感器件953均连接在MCU961和逻辑电路962之间。松紧调节机构40中的驱动组件44分别与MCU961和逻辑电路962连接。在一些实施例中,第一传感器件941、第二传感器件952和第三传感器件953可以均为霍尔元件,第一传感器件941通过检测第一磁体的磁场来确定软垫的厚度。第二传感器件951和第三传感器件952通过检测第二磁体的磁场来确定系带组件20的伸缩状态。
以上述实施例的头戴设备100为例,对本申请的松紧调节机构的调节原理进行说明:在未使用时头戴设备100时,头戴设备100的系带组件20处于伸长到最长的第一状态。
当用户将头戴设备100戴于头部后,用户先触发控制开关97使其处于第二控制状态,处理器96接收到从控制开关97发来的对应于第二控制状态的信号之后,控制第一传感器件941和第三传感器件953开始检测,同时向松紧调节机构40的驱动组件44(例如,驱动组件44的电机)发出沿第一方向转动的调节信号以控制驱动组件44沿第一方向转动,使得传动齿轮430带动配合齿轮428转动沿第一方向转动,从而带动第一头带21和第二头带22做相向运动,使得第一头带21和第二头带22之间的重叠长度增加,以使系带组件20的整体长度缩短。同时驱动组件44的电机将自身的转动信息反馈至MCU961,第一传感器件941和第三传感器件953将自身的感测信息反馈至MCU961。
随着系带组件20的整体长度逐渐缩短,软垫522逐渐被挤压在用户头部和固定板521之间,软垫522收到挤压力而发生变形,厚度逐渐减小。当第一传感器件941软垫522的厚度减小到预设阈值时,例如,减小到0.5cm时,逻辑电路962继而发出控制信号控制驱动组件44的电机停止转动,从而使得配合齿轮428停止转动,以使第一头带21和第二头带22停止运动,从而停止对系带组件20的收缩调节。驱动组件44的电机同时将自身停止转动的信息反馈至MCU。
可以理解地,若用户并没有将头戴设备100配戴在头部,而直接触发控制开关97使其处于第二控制状态,处理器96的控制与上述控制过程类似,不同的是,由于头戴设备100并未被配戴在用户头部,因而软垫522未被挤压,因此,第一传感器941检测到的软垫522的厚度并未发生变化。直至系带组件20的整体长度逐渐缩短至最短,此时,第三传感器件953检测到系带组件20处于第二状态,逻辑电路962继而发出控制信号控制驱动组件44的电机停止转动,从而使配合齿轮428停止传动,从而防止第一头带21和第二头带22转堵。同时,驱动组件44的电机将自身停止转动的信息反馈至MCU。
当用户要将头戴设备100从头部取下时,用户先触发控制开关97使其处于第一控制状态,处理器96接收到从控制开关97发来的对应于第一控制状态的信号之后,控制第二传感器件952开始检测,同时向松紧调节机构40的驱动组件44(例如,驱动组件44的电机)发出沿第二方向转动的调节信号,其中,第二方向与第一方向相反,使得传动齿轮430带动配合齿轮428沿第二方向转动,从而带动第一头带21和第二头带22做相背运动,使得第一头带21和第二头带22之间的重叠长度减小,以使系带组件20的整体长度增加。同时驱动组件44的电机将自身的转动信息反馈至MCU961,第二传感器件952将自身的感测信息反馈至MCU961。
随着系带组件20的整体长度逐渐增加,当系带组件20的整体长度增加到一定长度时,用户可以将头戴设备100从其头部取下,而系带组件20的整体长度继续增加,直至伸长到最长。此时,第二传感器件952检测到系带组件20处于第一状态,逻辑电路962继而发出控制信号控制驱动组件22的电机停止转动,使配合齿轮428停止转动,从而使第一头带21和第二头带22停止相背运动,以防止第一头带21和第二头带22转堵。同时,驱动组件44的电机将自身停止转动的信息反馈至MCU。
综上所述,本申请通过设置第一传感器来检测软垫的厚度,通过松紧调节机构根据第一传感器检测到的软垫的厚度来调节系带的长度,从而实现了自动调节系带的长度,使得系带长度的调节更方便,用户体验更好。
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。
