汽车投影帘及投影系统、遮阳收卷帘固定装置及收卷帘 技术领域
本发明涉及汽车用品领域，特别涉及一种带遮阳功能的汽车车载移动投影帘及投影系统、汽车前挡风玻璃遮阳收卷帘固定装置及收卷帘。
背景技术
随着生活水平的提高，汽车越来越普及，人们对汽车配置的要求越来越高，但目前汽车上的娱乐系统仅在仪表板上装有导航多媒体系统，但受屏幕大小的限制，乘客无法舒适地欣赏视频及音频。
此外，当前市场上各种汽车在出厂前汽车内部均没有遮阳帘，有些中高档轿车也只有后排左右窗上有遮阳帘，在炎热的夏季，汽车在太阳底下停放一段时间后，车内温度会迅速升高，不仅使人无法适应车内的温度，进入车内前必须先开车窗开空调降温，而且会加速车内各部件的老化，因此很多汽车玻璃上都贴上遮阳膜，但为了视野需求，汽车前挡风玻璃是无法贴膜的，人们通常用遮阳帘来遮住前挡风玻璃，开车时再取下。
目前的前挡风玻璃遮阳帘，大多为左右拉开式的，这种方式不能与挡风玻璃进行较好的贴合，并且由于从左向右拉开后遮阳帘布的伸出长度较大，在收卷时容易使帘布的边缘卷曲，造成帘布的收卷不平整，容易被卡死，从而造成遮阳帘的损坏，并且帘布回收时需全程手持遮阳帘下杆平行回收。而且现有的遮阳帘在拉出后，拉出端必须持续手持并及时进行固定，不然便会因弹性自动收回，此外，现有的遮阳帘均采用真空吸盘固定在前挡风玻璃上，这种固定方式不牢固，太阳晒久了或遇到小颠簸时就会脱落，影响使用效果和行车安全，只能是使用时当场进行固定操作，并不适合长时间悬挂在前挡风玻璃的顶部。
发明内容
本发明的目的在于提供一种带遮阳功能的汽车车载移动投影帘，该投影帘设有阻离组合结构，投影帘布拉出时能在任意地方悬停，拉出端无需再进行固定，不仅能用于投影，根据投影面积大小拉出对应的长度，使乘客具有更好的娱乐体验，而且能应用于汽车前挡风玻璃的遮阳，此外，按下阻离解锁装置时，投影帘布能在收卷装置、单向器和单向摩擦组件的作用下匀速地自动收回，便捷度高，使用寿命长。
本发明的另一目的在于，提供一种汽车前挡风玻璃遮阳收卷帘固定装置， 该固定装置采用万向连接件连接于左右两端的汽车遮阳板固定轴，同时采用真空吸附件吸附于汽车前挡风玻璃上，不仅固定牢固可靠，适用于所有车型，而且能适应上下拉开式的遮阳收卷帘，不使用时可挂置于车上，不影响使用效果和行车安全。
本发明的又一目的在于，提供一种汽车前挡风玻璃遮阳收卷帘，该收卷帘设有阻离组合结构，遮阳帘拉出时能在任意地方悬停，拉出端无需再进行固定，不仅能应用于停车时全遮的场合，操作简单，而且能应用于行车过程中的遮阳，此外按下阻离解锁装置时，遮阳帘能在扭力弹簧和单向阻尼器的作用下匀速地自动收回，便捷度高，使用寿命长。
本发明是这样实现的：
方案(一)：
一种带遮阳功能的汽车车载移动投影帘，其特征在于：包括固定外管、同轴固设于固定外管内的中轴、活动套设于中轴外周的卷帘管、一端卷绕于卷帘管上的投影帘布、设置于中轴和卷帘管之间的用于使投影帘布自动收回的收卷装置、设置于卷帘管和固定外管之间的用于在投影帘布自动收回时实现单向匀速作用的单向器、设置于卷帘管和固定外管之间的用于使投影帘布能拉出悬停的阻离组合结构以及设置于固定外管和阻离组合结构之间的用于解除投影帘布单向拉出限制的阻离解锁装置，所述单向器包括固定连接于卷帘管上的单向外管、同轴套设于单向外管内的单向内管以及连接于单向外管和单向内管之间的单向弹簧，所述单向弹簧活动套设于单向内管的外周壁上，所述单向弹簧的一端与单向外管相连接使得单向弹簧和单向外管不能相对转动，所述单向弹簧的螺旋方向与投影帘布收回时卷帘管的转动方向相同使得投影帘布收回时单向外管能通过单向弹簧带动单向内管转动，所述投影帘还包括连接于单向内管和固定外管之间的用于在投影帘布收回时产生摩擦阻力的单向摩擦组件。
为了能使投影帘布在收回时产生摩擦阻力，从而实现匀速收回，所述固定外管位于单向器一端的端面上固设有左端盖，所述单向摩擦组件包括与单向内管相连接传动的甩件、一个以上设置于甩件上的甩珠槽以及安装于各个甩珠槽内的甩珠，所述左端盖上设有与甩件相匹配的甩件腔，所述投影帘收回时甩珠能沿甩珠槽甩出与甩件腔相摩擦从而产生摩擦阻力。
为了能进一步增大单向摩擦组件的摩擦力，所述投影帘还包括一组以上连接于单向内管和甩件之间的增速齿轮组。
为了降低组装难度，同时使收卷装置能达到预设的预紧力，所述左端盖上设有用于固定中轴的中轴固定螺栓，所述中轴固定螺栓的轴线与中轴的轴线相垂直，所述左端盖上还设有用于旋转中轴以对收卷装置进行预紧的预紧操作孔。

为了能解除投影帘布的单向拉出限制，所述阻离解锁装置包括滑动连接于右端盖上的阻离解锁按键，所述阻离解锁按键的下端位于压杆自由端上方，所述阻离解锁按键向右端盖内滑动时能下压压杆自由端使得棘爪脱离棘轮以解除棘轮单向转动的限制。
为了能更好地固定投影帘，所述投影帘还包括两个以上设置于固定外管上的投影帘固定装置，所述投影帘固定装置包括与投影帘相连接的滑动箍套、连接于滑动箍套和汽车前挡风玻璃之间的真空吸附件以及连接于滑动箍套和汽车遮阳板固定轴之间且长度和角度均可调的万向连接件，所述滑动箍套滑动连接于固定外管外周壁上且能沿固定外管轴向滑动；所述万向连接件包括主杆件、连接于主杆件和滑动箍套之间且角度可调的蛇形管以及连接于主杆件和汽车遮阳板固定轴之间的U型螺纹扣，所述主杆件外周壁设有两条沿主杆件轴向分布的可供U型螺纹扣U型开口两侧边伸入的滑槽，所述万向连接件还包括活动套设于主杆件外周上的调节螺母以及设置于主杆件外周壁上的用于限制调节螺母向U型螺纹扣一端轴向移动的限位凸缘，所述调节螺母的内周壁与U型螺纹扣U型开口两侧边的外壁螺纹连接使得调节螺母将U型螺纹扣U型开口两侧边压迫在主杆件的滑槽内且旋转调节螺母时能使U型螺纹扣在滑槽上滑动。
进一步地，所述主杆件下端设有用于供蛇形管伸入的喇叭口，所述万向连接件还包括设置于蛇形管和嗽叭口之间的蛇形管箍紧套，所述蛇形管箍紧套的内周壁与蛇形管相配合，所述蛇形管箍紧套的外周壁与喇叭口相配合且外周壁形状与喇叭口相匹配，喇叭口外周套设有缩口螺母，所述缩口螺母上端内周壁与主杆件外周壁螺纹连接，所述蛇形管箍紧套下端设有与缩口螺母相配合的凸台使得缩口螺母旋紧时逐渐往上推动蛇形管箍紧套，从而蛇形管箍紧套和蛇形管的伸入端进行固定，所述蛇形管的另一端与滑动箍套固定连接。
为了能隐藏电话号码并在需要的时候进行展示，所述投影帘还包括转动连接于滑动箍套上的电话号码安装板，所述安装板上设有十一个用于安装数字颗粒的安装槽。
方案(二)：
一种汽车车载移动投影系统，其特征在于：包括带遮阳功能的汽车车载移动投影帘以及微型投影仪。
方案(三)：
一种汽车前挡风玻璃遮阳收卷帘固定装置，其特征在于：包括与收卷帘相连接的滑动箍套、连接于滑动箍套和汽车前挡风玻璃之间的真空吸附件以及连接于滑动箍套和汽车遮阳板固定轴之间且长度和角度均可调的万向连接件。
所述万向连接件包括主杆件、连接于主杆件和滑动箍套之间且角度可调的蛇形管、连接于主杆件和汽车遮阳板固定轴之间的U型螺纹扣以及中间的防滑垫，所述主杆件外周壁设有两条沿主杆件轴向分布的可供U型螺纹扣U型开口两侧边伸入的滑槽，所述万向连接件还包括活动套设于主杆件外周上的调节螺母以及设置于主杆件外周壁上的用于限制调节螺母向U型螺纹扣一端轴向移动的限位凸缘，所述调节螺母的内周壁与U型螺纹扣U型开口两侧边的外壁螺纹连接使得调节螺母将U型螺纹扣U型开口两侧边压迫在主杆件的滑槽内且旋转调节螺母时能使U型螺纹扣在滑槽上滑动，且U型螺纹扣可根据不同车型遮阳板固定轴的直径大小来调整滑动距离并将防滑垫与主杆件与锁死在遮阳板固定轴上。
所述主杆件内设有用于供蛇形管伸入的内圆管道，蛇形管伸入内圆管道内长度可调，且主杆件下端设有喇叭口，喇叭口外周套设有缩口螺母，所述缩口螺母内周壁与主杆件外周壁螺纹连接且内周壁随着缩口螺母的旋转逐渐对喇叭口进行收紧，从而将喇叭口和蛇形管的伸入端进行固定。所述蛇形管的另一端与滑动箍套通过螺纹连接进行固定，不同车型前挡风玻璃与汽车遮阳板固定轴的距离不同，可根据蛇形管伸入内圆管道的距离来调整。同时由于不同车型的前挡风玻璃的弯曲弧度也不相同，可以通过弯曲蛇形管的角度使得真空吸附件与各车型的前挡风玻璃相匹配从而达到最佳的吸附效果。
所述真空吸附件为真空吸盘。作为一种优选的方案，真空吸盘通过L型固定件与滑动箍套进行连接，L型固定件的一端与滑动箍套固定连接，真空吸盘可转动地连接于L型固定件的另一端上并通过螺栓进行固定，松开螺栓可转动真 空吸盘的角度，使得真空吸盘能与前挡风玻璃进行较好地贴合，能适应各种车型前挡风玻璃的弯曲弧度，适应性更强。
方案(四)：
一种汽车前挡风玻璃遮阳收卷帘，其特征在于：包括固定套管、同轴固设于固定套管内的中轴、活动套设于中轴外周的卷帘管、一端卷绕于卷帘管上的遮阳帘、设置于中轴和卷帘管之间的用于使遮阳帘自动收回的收卷装置、设置于卷帘管和固定套管之间的用于实现遮阳帘自动匀速收回作用的单向阻尼器、设置于卷帘管和固定套管之间的用于使遮阳帘能拉出悬停的阻离组合结构以及设置于固定套管和阻离组合结构之间的用于解除遮阳帘单向拉出限制的阻离解锁装置。所述中轴和卷帘管之间还设有一个以上的过桥垫圈，用于防止中轴过长时出现弯曲，影响使用效果。
所述单向阻尼器用于实现拉遮阳帘时不受单向阻尼器的阻力作用，在遮阳帘自动回收时，由于扭力弹簧变形释放力大于单向阻尼器的阻力，带动阻尼器阻尼外管匀速旋转，达到遮阳帘匀速回收的效果。
所述单向阻尼器包括固定连接于卷帘管上的阻尼外管以及同轴设置于阻尼外管内的阻尼内管，所述固定套管位于单向阻尼器一端的端面上固设有左端盖，所述阻尼内管与左端盖固定连接；所述阻尼内管同轴活动套设于中轴外周壁。
作为另一种优选的方案，所述左端盖内设有限位缓冲槽，所述阻尼内管上固设有限位凸台，所述限位凸台活动装配于限位缓冲槽内使得阻尼内管转动设定的角度后不再沿同一方向转动。由于收卷帘向下拉开到预定位置后，扭力弹簧处于变形崩紧状态，刚要缩回时，初始释放的弹力比较小，因此设置限位缓冲槽使其初始收回时不受阻尼作用，使遮阳帘收回更顺畅。
所述扭力弹簧的小端固设于中轴上，扭力弹簧内壁与中轴之间设有内消声套，扭力弹簧外壁与卷帘管内壁直径设有外消声套，扭力弹簧大端固设与同轴套端部，同轴套与卷帘管同轴固设。在拉帘时，卷帘管带动扭力弹簧旋转，弹簧收紧变形，储存能量。

所述阻离解锁装置包括滑动连接于左端盖上的阻离解锁按键，所述阻离解锁按键的下端位于压杆自由端上方，所述阻离解锁按键向左端盖内滑动时能下压压杆自由端使得棘爪脱离棘轮以解除棘轮单向转动的限制。
所述收卷帘还包括两个以上的收卷帘固定装置，所述滑动箍套滑动连接于固定套管外周壁上且能沿固定套管轴向滑动。所述滑动箍套可根据不同车型左右汽车遮阳板固定轴的相对位置的距离来调整在收卷帘两端上的安装位置。
所述收卷帘还包括连接于固定套管和汽车观后镜支架之间的观后镜固定装置，所述观后镜固定装置包括滑动连接于固定套管上的滑动中间箍套、可拆卸地固设于滑动中间箍套上的固定活扣、一端转动连接于固定活扣上的调节件一、与调节件一相配合的调节件二、连接于节件一和调节件二之间的螺栓螺帽固定装置、转动连接于调节件二上的偏心蹄以及连接于偏心蹄和汽车观后镜支架之间的尼龙扎带，所述调节件一和调节件二的配合面上设有相匹配的锯齿使得调节件一和调节件二的配合位置可调，所述偏心蹄上设有通孔，所述尼龙扎带穿过通孔后与汽车观后镜支架固定连接。
所述收卷装置为连接于中轴和卷帘管之间的扭力弹簧。
所述遮阳帘的拉出端固设有拉帘杆，所述拉帘杆靠近前挡风玻璃的一侧设有燕尾滑槽，所述燕尾滑槽内滑动连接有由十一个数字颗粒组成的车主电话。
所述扭力弹簧内壁与中轴之间设有内消声套，所述扭力弹簧外壁与卷帘管内壁之间设有外消声套。
较之现有技术而言，本发明具有以下优点：
(1)本发明提供的带遮阳功能的汽车车载移动投影帘，设有阻离组合结构，投影帘布拉出时能在任意地方悬停，拉出端无需再进行固定，不仅能应用于停车时全遮的场合，操作简单，而且能应用于行车过程中的遮阳，此外按下阻离解锁装置时，投影帘布能在收卷装置、单向器和单向摩擦组件的作用下匀速地自动收回，便捷度高，使用寿命长；
(2)本发明提供的带遮阳功能的汽车车载移动投影帘，作为汽车遮阳帘时， 不仅能应用于停车时全遮的场合，而且拉出时能在任意位置悬停，能应用于行车过程中的遮阳，此外，固定牢固，不影响使用效果和行车安全；
(3)本发明提供的带遮阳功能的汽车车载移动投影帘，在投影帘布拉出时，由于卷帘管转动方向与单向弹簧的螺旋方向相反，单向弹簧变松，从而不动带动单向内管转动，拉出时不受单向摩擦组件的阻力作用，在投影帘布收回时由于卷帘管转动方向与单向弹簧的螺旋方向相同，单向弹簧变紧，从而带动单向内管转动，单向内管带动甩件转动，甩件中的甩珠甩出与甩件腔进行摩擦，使投影帘布匀速收回；

如图12所示，所述主杆件31下端设有用于供蛇形管32伸入的喇叭口313，所述万向连接件3还包括设置于蛇形管32和嗽叭口131之间的蛇形管箍紧套36，所述蛇形管箍紧套36的内周壁与蛇形管32相配合，所述蛇形管箍紧套36的外周壁与喇叭口313相配合且外周壁形状与喇叭口313相匹配，喇叭口313外周套设有缩口螺母35，所述缩口螺母35上端内周壁与主杆件31外周壁螺纹连接，所述蛇形管箍紧套36下端设有与缩口螺母35相配合的凸台使得缩口螺母35旋紧时逐渐往上推动蛇形管箍紧套36，从而蛇形管箍紧套36和蛇形管32的伸入端进行固定，所述蛇形管32的另一端与滑动箍套1固定连接。
