本发明提出一种头戴式设备。
在本发明一实施例中，如图1、图5和图6所示，该头戴式设备，包括：
电池仓100，设有电池槽110、及与所述电池槽110连通的出烟口120，所述电池槽110用以供电池130安装；以及
壳体200，设有排烟口210，所述壳体200内设有所述电池仓100和排烟通道220，所述排烟通道220的一端与所述出烟口120连通，另一端与所述 排烟口210连通；
在所述电池130燃烧时，所述排烟通道220能使燃烧烟雾排出至外界环境。
在本发明中，该头戴式设备的壳体200中设有电池仓100，电池仓100内具有供电池130安装的电池槽110，及供电池130排出燃烧烟雾的出烟口120；不失一般性，本实施例中，壳体200包括前壳201和中壳202，排烟口210形成于前壳201和后壳之间的接缝处，排烟口210连通于外部环境，用于使燃烧烟雾排出壳体200；壳体200内还设有排烟通道220，排烟通道220连通于出烟口120与排烟口210之间，用于将燃烧烟雾引导至排烟口210。
现有技术中，壳体中并无专门的排烟通道以供燃烧烟雾排出，燃烧烟雾将弥漫于电池仓内部，电池燃烧产生的热量将于电池仓内积聚，导致电池仓内部的温度急剧上升，会对该头戴式设备的其他部件产生影响，严重时可能会导致爆炸的发生。
本发明中，在电池仓100内的电池130燃烧时，燃烧烟雾能通过其上设置的出烟口120排至排烟通道220，经过排烟通道220的引导，燃烧烟雾最终能从排烟口210排至外界环境，以使电池130燃烧产生的热量能随着燃烧烟雾排至外界环境中，从而避免对其他部件产生破坏。因此，在电池130燃烧时，本发明的头戴式设备可将燃烧烟雾排至外界环境，以使该头戴式设备的安全性能得以提升。
不失一般性，本实施例中，该头戴式设备为VR(Virtual Reality，虚拟现实)眼镜，当然，在其他实施例中，该头戴式设备也可以是AR(Augmented Reality，增强现实)眼镜、MR(Mediated Reality，混合现实)眼镜等。
进一步地，在本实施例中，如图7所示，所述电池槽110内设有防火套111，所述防火套111用以外套于所述电池130。可以理解，防火套111应具备阻燃性，以在电池130燃烧时推迟火焰蔓延，如此，在防火套111的保护下，能确保用户有足够的时间摘下该头戴式设备。进一步地，防火套111应采用V0防火材质，以提升其阻燃性，从而提升该头戴式设备的安全性能。
进一步地，在本实施例中，如图7所示，所述电池槽110用以供所述电池130间隙配合，以使电池130与电池仓100的内壁面留有距离。可以理解，在电池130燃烧时，其体积将发生膨胀。本实施例中，电池130与电池槽110 之间存在配合间隙，以供电池130膨胀，避免燃烧的电池130过度挤压电池仓100的壁面，而导致发生爆炸；进一步地，该配合间隙至少应满足可使电池130膨胀10％，以确保有足够的空间供电池130膨胀。
进一步地，在本实施例中，如图2和图5所示，所述壳体200内设有支架300，所述电池仓100安装于所述支架300，所述排烟通道220包括贯穿所述支架300设置的第一排烟段221，所述第一排烟段221具有靠近所述出烟口120设置的第一通道口2211；所述支架300与所述电池仓100之间设有第一密封环500，所述第一密封环500的一侧环绕所述第一通道口2211的周缘，另一侧环绕所述出烟口120的周缘。第一密封环500设于第一排烟段221与电池仓100的接缝处，以在出烟口120至第一通道口2211之间起密封作用，如此，在电池130燃烧时，自出烟口120排出的燃烧烟雾在通向第一排烟段221的过程中，不会向壳体200的其他位置扩散，确保燃烧烟雾能经由排烟通道220且只从排烟口210排出壳体200，从而提升该头戴式设备的安全性能。当然，在其他实施例中，也可以是，支架300与电池仓100一体成型，确保支架300与电池仓100连接处的密封性能，而不必另设密封环；还可以是，通过胶粘的方式密封出烟口120与第一通道口2211的连接处，同样可避免第一排烟段221与电池仓100之间产生接缝，进一步地，可采用热固性胶粘剂粘接，以避免在电池130燃烧时，因排烟通道220内的温度升高而导致粘接失效；亦或者，排烟通道220并不贯穿支架300，而是与支架300分立设置于壳体200内。
进一步地，在本实施例中，如图2和图5所示，所述支架300的背离所述电池仓100的一侧设有风扇400，所述壳体200对应所述风扇400设有出风口，所述排烟口210为所述出风口；所述壳体200还对应于所述风扇400设有出风风道，所述排烟通道220还包括与所述第一排烟段221连通的第二排烟段222，所述第二排烟段222为所述出风风道。如此，在电池130燃烧时，能够通过风扇400的作用进行散热，并加速燃烧烟雾排出，以进一步提升该头戴式设备的安全性能。
进一步地，在本实施例中，如图6所示，所述第一排烟段221还具有远离所述第一通道口2211的第二通道口2212，所述风扇400对应所述第二通道口2212设有排烟过孔410，所述第二排烟段222通过所述排烟过孔410连 通于所述第一排烟段221；所述支架300与所述风扇400之间设有第二密封环600，所述第二密封环600的一侧环绕所述第二通道口2212的周缘，另一侧环绕所述排烟过孔410的周缘。第二密封环600设于第二通道口2212与排烟过孔410之间，以密封二者之间的缝隙，保证排烟通道220只能从排烟口210出烟，从而提升该头戴式设备的安全性能。当然，在其他实施例中，也可以是，风扇400与支架300一体成型，以避免第一排烟段221与第二排烟段222之间产生接缝，同样可保证排烟通道220的排烟效果；还可以是，通过胶粘的方式密封第二通道口2212与排烟过孔410的连接处，同样可避免第一排烟段221与第二排烟段222之间产生接缝，进一步地，可采用热固性胶粘剂粘接，以避免在电池130燃烧时，因排烟通道220内的温度升高而导致粘接失效；亦或者，风扇上不设有排烟过孔，而是风扇内具有分立设置的第二排烟段，第二排烟段设有排烟过孔，并通过排烟过孔连接于第一排烟段。
进一步地，在本实施例中，如图6所示，所述第一排烟段221还具有远离所述第一通道口2211的第二通道口2212，所述头戴式设备还设有隔离件800，所述隔离件800位于能覆盖所述第二通道口2212的位置；在所述电池燃烧时，所述隔离件800能离开覆盖所述第二通道口2212的位置。具体地，在本实施例中，所述隔离件800设在所述风扇400在背离所述支架300的一侧，并覆盖于所述排烟过孔410，以起到覆盖第二通道口2212的作用，而在所述风扇400进行散热出风时使所述第一排烟段221与所述第二排烟段222互不连通；在所述电池130燃烧时，所述隔离件800能脱离所述风扇400，以在所述风扇400进行排烟出风时使所述第一排烟段221连通于所述第二排烟段222。
可以理解，该头戴式设备中还设有其他电子器件(如主板)，如此，在该头戴式设备的正常使用状态下，风扇400能进行散热出风，以使电子器件运行时产生的热量能通过经出风风道自出风口排出的热风排向外界，因此时的排烟过孔410上覆盖有隔离件800，因此，风扇400产生的热风不会向第一排烟段221扩散，也就不能进入电池仓100内，以避免电池130的工作温度升高，影响电池130的工作性能；在电池130燃烧时，因电池仓100温度的升高，导致隔离件800两侧的压力不一样，具体地，靠近第一排烟段221的一侧的压力更高，作用于隔离件800上能使其自风扇400上脱离，以使第 一排烟段221连通于第二排烟段222，而在风扇400的作用下，燃烧烟雾能够迅速地通过经排烟通道220自排烟口210排至外界，以保证该头戴式显示设备的安全性能。
而在其他不设置风扇的实施例中，隔离件800将直接设在支架300靠近所述第二通道口2212的一侧，并直接覆盖所述第二通道口2212，如此，在头戴式设备的正常使用状态下，外部环境的空气无法通过第一排烟段221进入电池仓100内；而在电池燃烧时，隔离件800可脱离支架300，以使第一排烟段221与外部环境导通。
进一步地，所述隔离件800采用粘接的方式连接在能覆盖所述第二通道口2212的位置，具体地，在本实施例中，所述隔离件800粘接于所述风扇400。如此，在电池130燃烧时，燃烧烟雾自出烟口120排至第一排烟段221，引起第一排烟段221内的温度升高，一方面，能使隔离件800与风扇400之间的粘接胶的粘性下降，一方面，能导致第一排烟段221内的压力升高，以破坏隔离件800与风扇400之间的粘接关系，致使隔离件800从风扇400脱落，第一排烟段221从而得以连通于第二排烟段222，燃烧烟雾因而能自排烟口210排至外界。当然，在其他实施例中，也可以是，隔离件800为插设于排烟过孔410的形状记忆片，当温度升高到一定水平，该形状记忆片的形状能发生变化，不再隔离第一排烟段221与第二排烟段222，也即在电池130燃烧时，该形状记忆片能导通第一排烟段221与第二排烟段222之间的通路。
进一步地，在本实施例中，所述隔离件800的材质为PET(Polyethylene terephthalate，聚对苯二甲酸乙二醇酯)材质。PET材质的隔离件800的耐热性能不高，热变形温度仅为85℃左右，可在电池130燃烧时，确保隔离件800的隔离作用能失效；另外，PET材质的隔离件800的气体渗透率低，有优良的阻气性能，能有效在风扇400散热出风时阻隔热风进入第一排烟段221，而影响电池仓100内的电池130的工作。当然，在其他实施例中，隔离件800也可以是PC(polycarbonate，聚碳酸酯)材质。
进一步地，在本实施例中，如图2至图4所示，所述电池仓100包括仓体101与盖体102，所述仓体101为敞口结构，所述盖体102盖设于所述仓体101，所述出烟口120设于所述盖体102。不失一般性，盖体102通过螺钉锁附的方式与仓体101连接，以使盖体102可拆卸地盖设于仓体101。可以 理解，该头戴式设备出厂时，其内部可以不配置有电池130，仓体101与盖体102分离的设置，可方便用户装入电池130。另外，在电池130发生其他故障时，也可方便地拆开盖体102，取出电池130，以对电池130进行检修或更换。盖体102上设有出烟口120，也即盖体102更靠近支架300设置，特别地，盖体102上的出烟口120的宽度小于1mm，以符合安规要求，为提升出烟口120的出烟效率，可在盖体102上设置多个出烟口120。又因燃烧烟雾会上飘，所以出烟口120可设于盖体102的上部区域，以促进燃烧烟雾从电池仓100内快速排出。
进一步地，在本实施例中，所述仓体101和所述盖体102的材质为防火材质，以避免在电池130燃烧时，电池仓100受电池130影响而发生燃烧，加剧火势。进一步地，所述仓体101和所述盖体102的材质采用V0防火材质，以提升其阻燃性，从而提升该头戴式设备的安全性能。不失一般性，盖体102的材为金属材质，金属材质既具备阻燃性，可提升电池仓100的安全性能，又具有一定的结构强度，能承受一定的外力作用，可避免仓体101内的电池130受到挤压。
进一步地，在本实施例中，如图2、图4和图7所示，所述仓体101与所述盖体102的连接处设有第三密封环700。可以理解，仓体101与盖体102的配合处也将产生缝隙，第三密封环700用以密封二者之间的接缝，以确保电池仓100内的燃烧烟雾只有盖体102上的出烟口120这一排出出口，避免燃烧烟雾通过盖体102与仓体101配合处的缝隙扩散至壳体200的其他部位。
可选地，在本实施例中，所述第一密封环500、第二密封环600、第三密封环700的材质均为泡棉材质。泡棉具有有弹性、重量轻、快速压敏固定、体积超薄、性能可靠等一系列特点，能在该头戴式设备中的不同结构的接缝处起到良好的密封作用。需要说明的是，用作第一密封环500、第二密封环600、第三密封环700的泡棉材料应具备阻燃性，避免其受到电池130燃烧的影响发生燃烧，而破坏排烟通道220的结构，以确保排烟通道220能使燃烧烟雾自排烟口210排至外界。
进一步地，在本实施例中，如图1和图2所示，所述壳体200形成有佩戴位203，所述排烟口210设于所述壳体200的远离所述佩戴位203的一端，所述出风风道朝远离所述佩戴位203的方向延伸。如此，出风风道排出的热 风或在电池130燃烧时排出的燃烧烟雾能朝远离用户面部的方向，避免其对用户面部造成不适或造成伤害，从而进一步提升该头戴式设备的安全性能。
以上所述仅为本发明的可选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
