头盔外壳1为碳纤维材料，使得头盔更轻，强度更高，外层涂有反射太阳辐射的涂料，能通过反射太阳辐射的方法来降温。头盔外壳1顶部开有全景摄像头孔5，用于全景摄像头的升降。头盔外壳1的前侧装有警徽2。头盔外壳1的两侧装有控制开关板6用于控制头盔功能与电子器件可通过导线实现电气连接。

头盔外壳1前部和摄像头框9配合，摄像头框9固定在头盔内部安装架8上，两者是一体成型的。摄像头框9中装有深度摄像头。
头盔外壳1内是头盔内部安装架8，电子控制主板12、全景摄像头升降机构16、智能眼镜驱动板17、智能眼镜升降机构18、骨传导耳机15、TYPE-C接口20、摄像头框9均安装固定在头盔内部安装架8上。智能眼镜升降机构18具有眼镜升降架181；眼镜升降架181上安装有智能眼镜182和通电变色遮阳板183，由智能眼镜升降机构18实现智能眼镜182和遮阳板183的升降功能。
内部安装架8采用镂空多余部分的设计思路，有益于减轻头盔重量， 加强头盔强度。头盔内部安装架8的后侧下部设有1个控制主板安装槽801，用于安装头盔的电子控制主板12。电子控制主板12和散热风扇21的位置相对应，散热风扇21主要是对电子控制主板12进行散热以及头盔内部空气流通。内部安装架8后侧的中部设有2个电池槽支撑孔座802和电池支撑槽面803用于支撑和固定散热盖板7和电池槽701。内部安装架8后侧的上部设有2个太阳能板支撑孔座805，用于支撑和固定散热盖板7和太阳能板槽702。
内部安装架8后侧，位于电池支撑槽面803和太阳能板支撑孔座805之间，设有1个骨传导驱动芯片固定座804，用于固定骨传导耳机15的骨传导驱动电路板1501，实现固定骨传导耳机15的固定。
内部安装架8的顶部设有4个全景摄像头升降机构支撑孔座806，用于固定支撑全景摄像头升降机构16。全景摄像头升降机构16的位置与全景摄像头孔5的位置相对应，全景摄像头升降机构16将全景摄像头伸出/回缩于全景摄像头孔5。
内部安装架8前侧的上部设有4个智能眼镜驱动板支撑孔座807，用于安装固定智能眼镜驱动板17。
内部安装架8的左右两侧设有2个骨传导轴孔808，骨传导耳机支撑架23绕骨传导轴孔808旋转连接。骨传导耳机15安装在骨传导耳机支撑架23上，并随着骨传导耳机支撑架23绕骨传导轴孔808转动。
内部安装架8的左右两侧且处于骨传导轴孔808的前方，设有2个智能眼镜架轴孔809，智能眼镜架181绕智能眼镜架轴孔809旋转连接。智能眼镜升降机构18固定在内部安装架8的前侧，且处于智能眼镜驱动 板17的前侧。智能眼镜升降机构18驱动智能眼镜架181绕智能眼镜架轴孔809转动。
内部安装架8底部的内侧设有6个内饰安装孔810，用于安装和穿戴者头部直接接触的内饰。内部安装架8底部的外侧设有6个外壳安装孔811，通过连接件将头盔内部安装架8和头盔外壳1安装固定在一起。
头盔内部安装架8的左右两侧分别有两个阶梯槽812用于调整骨传导耳机支撑架23间的距离，从而调整骨传导耳机15相对于头盔穿戴者头部的位置。麦克风阵列19固定在智能眼镜升降机构18上，并通过智能眼镜升降机构18安装在头盔内。TYPE-C接口20设置在头盔内部安装架8后侧的底部。
如图12至图17所示，全景摄像头升降机构16包括：定位板161、摄像头马达162、运动板163、摄像头座164、摄像头165、复位弹簧166、遮挡盖167、导轨组件168和摄像头光电开关169。
定位板161具有四个螺丝孔161-1，与内部安装架8的顶部设有4个全景摄像头升降机构支撑孔座806相配，通过螺钉将定位板161固定在内部安装架8上，即固定在壳体结构上。定位板161底部具有两个对称设置的滑槽161-2。运动板163的两侧嵌入滑槽161-2，运动板163在滑槽161-2内可水平滑动。定位板161的一侧具有贯穿上下的底座槽161-3，摄像头座164在底座槽161-3内可上下移动。
摄像头马达162通过轴孔固定在定位板161一侧的下方，摄像头马达162为N20微型减速电机，具有输出齿轮162-1。
运动板163的下部具有齿条163-1。齿条163-1与摄像头马达162的 输出齿轮162-1啮合。运动板163的下方具有两个对称设置的斜面压板163-2。
摄像头165固定在摄像头座164的上端。摄像头座164的下端穿过定位板161的底座槽161-3。摄像头座164的下端具有弹簧导向孔164-1。弹簧导向孔164-1的端部具有弹簧凸台164-1a。复位弹簧166的一端套在弹簧凸台164-1a，另一端顶在内部安装架8的上表面，即设置在摄像头座164和内部安装架8之间。摄像头座164底部的两侧对称设置斜面凸台164-2。两个斜面凸台164-4的斜面与运动板163上的两个斜面压板163-2的斜面的位置和斜度相配，且两者贴合。
当给摄像头马达162一个正转的电驱动信号时，摄像头马达162的输出齿轮162-1顺势针旋转和运动板163上的齿条163-1配合，带动运动板163向右平移，即运动板163向摄像头座164的方向移动。当运动板163向右平移时，将通过斜面压板163-2下压摄像头座164的斜面凸台164-2。摄像头座164受定位板161上底座槽161-3的约束，在运动板163的带动下，竖直向下运动，固定在摄像头座164上的摄像头165一起竖直向下运动，从头盔外壳1顶部的全景摄像头孔5降下，此时复位弹簧166被压缩。
当摄像头马达162接收反转的电驱动信号时，将通过输出齿轮162-1和齿条163-1带动运动板163左移，即运动板163远离摄像头座164的方向移动。运动板163上的斜面压板163-2随之向左移动，摄像头座164斜面凸台164-2受到的向下压力撤销，摄像头座164在复位弹簧166的作用下向上移动，摄像头165随之竖直向上移动，从头盔外壳1顶部的 全景摄像头孔5伸出。
运动板163的另一侧具有U型槽161-4，U型槽161-4的开口竖直向上。
导轨组件168包括：左导轨片168a和右导轨片168b。左导轨片168a和右导轨片168b都呈L型，底边通过螺丝孔对称地固定在定位板161上端的两侧。左导轨片168a和右导轨片168b上都具有两条平行的倾斜导轨168-1。倾斜导轨168-1斜向上，靠近U型槽161-4的水平位置低，靠近摄像头座164的水平位置高。倾斜导轨168-1分为两段式，前端的斜率小于后端的斜率。
遮挡盖167的一端具有竖直的嵌入凸台167-1，两侧分别具有两个滑行凸台167-2。嵌入凸台167-1嵌入U型槽161-4，两者的形状和位置相配，滑行凸台167-2嵌入倾斜导轨168-1，两者的位置和形状相配。遮挡盖167的上端固定有橡胶片167-3。
遮挡盖167设置在左导轨片168a和右导轨片168b之间，嵌入凸台167-1嵌入运动板163的U型槽161-4内。
当运动板163向右运动时，即摄像头165下降过程，运动板163的U型槽161-4带动遮挡盖167同向向右移动，遮挡盖167同时沿着倾斜导轨168-1斜向上运动。当摄像头165下降到退出全景摄像头孔5时，遮挡盖167刚好带着橡胶片167-3堵住全景摄像头孔5。当头盔摄像头孔被完全堵住时，摄像头马达162停止转动，摄像头165到达下极限位置，从而实现了摄像头165的下降保护功能，并具有一定的防水效果。
当运动板163向左运动时，即摄像头165上升过程。运动板163的U 型槽161-4带动遮挡盖167同向向左移动，遮挡盖167同时沿着倾斜导轨168-1斜向下运动。当橡胶片167-3离开全景摄像头孔5时，摄像头165刚好升至全景摄像头孔5时的底部，持续上升一段时间后，摄像头165将到达工作位置即上极限位置，摄像头马达162停止转动，从而实现了摄像头165的上升功能。
本实施例中，摄像头165的上极限位置和下极限位置的控制，由摄像头光电开关169和两个定位挡片配合实现。
摄像头光电开关169通过螺丝孔柱，固定在定位板161的下方。运动板163的下方设置有上定位挡片163-3和下定位挡片163-4，且处于摄像头光电开关169的两侧。本实施例中，上定位挡片163-3处于下定位挡片163-4的左侧。
当摄像头马达162带动运动板163向右运动，当运动到右极限位置时，下定位挡片163-4会遮挡摄像头光电开关169，从而给头盔中的电子控制电路以到位信号，从而实现对摄像头马达162制动，让摄像头165停在下极限位置。
当摄像头马达162带动运动板163向左运动，当运动到左极限位置时，上定位挡片163-3会遮挡摄像头光电开关169，从而给头盔中的电子控制电路以到位信号，从而实现对摄像头马达162制动，让摄像头165停在上极限位置。
运动板163的左右极限位置同时也是摄像头165升降的上下极限位置。
当然，摄像头165的上极限位置和下极限位置的控制，还可以通过 摄像头马达162每次驱动设定的行程后，自动停止而实现。摄像头马达162的启动由操作人员，操作控制开关板6进行启动。
如图18至图24所示，智能眼镜升降机构18包括：眼镜升降架181、智能眼镜182、遮阳板183、弧形齿条184、眼镜马达185、马达固定座186和眼镜光电开关187。
本实施例中，眼镜升降架181包括：外圆弧杆181-1、内圆弧杆181-2和两个连接杆181-4。外圆弧杆181-1和内圆弧杆181-2的两端固定在一起，且端部具有凸轴181-3。两个连接杆181-4对称设置，每个连接杆181-4的两端分别与外圆弧杆181-1、内圆弧杆181-2固定连接。外圆弧杆181-1、内圆弧杆181-2和两个连接杆181-4可以一体成型。凸轴181-3嵌入内部安装架8的左右两侧的智能眼镜架轴孔809内，实现眼镜升降架181绕内部安装架8的转动连接。
智能眼镜182固定在内圆弧杆181-2的外侧面上。遮阳板183固定在外圆弧杆181-1的上。弧形齿条184的一端固定在内圆弧杆181-2的中间位置，另一端紧贴内部安装架8上。智能眼镜182、遮阳板183、弧形齿条184都随着眼镜升降架181的转动而转动。
马达固定座186安装在内部安装架8上，且处于眼镜升降架181上极限位置的上方。马达固定座186通过螺丝紧固，是固定不动的。眼镜马达185固定在马达固定座186上，实现眼镜马达185固定在内部安装架8上。马达固定座186中间具有避让孔186-1，弧形齿条184从避让孔186-1中穿过。
眼镜马达185的输出轴上具有齿轮185-1。齿轮185-1和弧形齿条 184啮合。弧形齿条184两侧可以设置导槽或导轨，限制弧形齿条184移动方向，使得弧形齿条184的移动更稳定。
当眼镜马达185通电旋转时，会带动齿轮185-1转动，并通过齿轮185-1和弧形齿条184的配合将眼镜马达185的旋转运动，转化为弧形齿条184的升降运动，从而带动眼镜升降架182绕内部安装架8上的智能眼镜架轴孔809的旋转运动，并实现了眼镜升降架182的升降运动，从而带动了眼镜升降架182上的智能眼镜182和遮阳板183的升降运动，从而实现了对智能眼镜182的保护功能。智能眼镜182的前方安装有遮阳板183，可遮挡环境中的强光，从而增强智能眼镜182的显示效果并且对智能眼镜182也有一定的保护作用。
本实施例中，智能眼镜182的上极限位置和下极限位置的控制，由眼镜光电开关187和两个限位挡片配合实现。
眼镜光电开关187通过开关固定夹187-1，固定在马达固定座186上，即实现固定在内部安装架8上。弧形齿条184一侧的上端具有上限位挡片184-1，下端具有下限位挡片184-2，且处于眼镜光电开关187的两侧。
当眼镜马达185的齿轮185-1在弧形齿条184上移动至上极限位置时，上限位挡片184-1会遮挡眼镜光电开关187，从而给头盔中的电子控制电路以到位信号，从而实现对眼镜马达185的制动，让智能眼镜182停在上极限位置。
当眼镜马达185的齿轮185-1在弧形齿条184上移动至下极限位置时，下限位挡片184-2会遮挡眼镜光电开关187，从而给头盔中的电子 控制电路以到位信号，从而实现对眼镜马达185的制动，让智能眼镜182停在下极限位置。
当然，智能眼镜182的上极限位置和下极限位置的控制，还可以通过眼镜马达185每次驱动设定的行程后，自动停止而实现。眼镜马达185的启动由操作人员，操作控制开关板6进行启动。
需要说明的是，在本文中，诸如向左、向右、顺指针、逆时针的关系术语仅仅针对附图中所示的位置进行方向性的描述，并不能用于对方案进行限定。术语“相连”、“连接”、“连接到”或者其他变体，不仅仅包括将两个实体直接相连接，也包括通过具有有益效果的其他实体间接相连接。
以上实施例仅描述了本方案的主要特征和创新点。本领域的技术人员应该了解，本方案不受上述实施例的限制。在不脱离本发明创新点和保护范围的前提下，本方案还会有各种变化，这些变化和改进都将落入本方案要求保护的范围内。
