车载幕布装置及车辆
本申请要求在2024年5月11日提交中国国家知识产权局、申请号为202410584745.0、发明名称为“车载幕布装置及车辆”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及投影技术领域，更具体地，涉及一种车载幕布装置及车辆。
背景技术
随着车辆技术的发展，在车辆座舱中设置幕布成为可能，为用户提供更丰富的智能化体验。当前，车载幕布往往固定设置于座舱的顶棚附近。
在实际场景中，某些车型可能会设置有天窗，比如，可开启的手动天窗或电动天窗、可开启或不可开启的全景天窗、分段式天窗等。当车辆设置有天窗时，一方面，幕布的布置位置不合理可能会影响天窗的功能，另一方面，幕布的布置方式严重依赖于车辆的结构。
因此，如何合理地设置车载幕布成为需要解决的问题。
发明内容
本申请提供了一种车载幕布装置及车辆，在车辆设置有天窗的情况下，能够显著降低车载幕布的布置难度，可以避免车载幕布对天窗、天窗遮阳帘的使用的干扰。
第一方面，提供了一种车载幕布装置。该车载幕布装置(20)包括：幕布主体(201)、幕布导轨(202)和滑动机构(203)。其中，幕布导轨(202)集成于车辆(1)的天窗框架总成(11)；幕布主体(201)与滑动机构(203)固定连接，滑动机构(203)与幕布导轨(202)滑动连接。
本申请实施例中，由于幕布主体(201)与滑动机构(203)固定连接，且滑动机构(203)与幕布导轨(202)滑动连接，使得幕布主体(201)能够在幕布导轨(202)的导向方向上相对于幕布导轨(202)移动。一方面，允许用户根据其需求调整幕布主体(201)的位置，使得幕布主体(201)的布置位置可以不再受限于座舱中的座椅等装置的分布的限制，可以避免幕布主体(201)影响用户对天窗、天窗遮阳帘的使用。另一方面，当用户在使用幕布时，可以通过调节幕布主体(201)的位置来调节观影距离，使得用户无需调整自身所在的位置，可以提升用户的使用体验。
而且，由于幕布导轨(202)集成于天窗框架总成(11)，使得幕布导轨(202)能够被车辆的内饰件遮挡，有利于降低幕布导轨(202)对座舱造型美观性的劣化。另外，相较于将幕布导轨(202)设置于车辆的其他位置(比如设置于车架等承载装置)的方案，将幕布导轨(202)集成于天窗框架总成(11)，可以缩小幕布主体(201)与幕布导轨(202)间的距离，能够采用体积较小/重量较轻的滑动机构(203)实现对幕布主体(201)的固定，有利于降低零件成本。
一些可能的实现方式中，车载幕布装置(20)还可以包括制动机构(206)。制动机构(206)可以用于：在制动状态下，维持幕布主体(201)与幕布导轨(202)间的相对位置不变。
本申请实施例中，通过设置制动机构，幕布主体(201)可以维持在当前位置而不会沿幕布导轨(202)移动，可以避免在使用幕布时幕布主体(201)沿幕布导轨窜动而影响用户的观影体验。
一些可能的实现方式中，制动机构(206)可以包括开关(2061)、传动件(2062)、弹性件(2063)和制动块(2064)。弹性件(2063)可以用于：在制动状态下，提供制动块(2064)贴合与幕布导轨(202)的压力。传动件(2062)可以将制动块(2064)传动连接至开关(2061)，其中，开关(2061)在第一方向上的移动可以带动制动块(2064)在第二方向上的运动，以使制动机构(206)处于制动状态或解除制动状态。
本申请实施例中，通过设置弹性件(2063)，制动机构(206)能够在无需用户操作的情况下，将幕布主体(201)维持于当前位置；通过设置传动件(2062)，能够以比较简单的结构使得制动机构(206)进入/解除制动状态，有利于简化制动机构的结构。
一些可能的实现方式中，幕布导轨(202)的端部可以设置有磁性元件(207)。磁性元件(207)可以用于滑动机构(203)处于该端部时磁性固定滑动机构(203)。
本申请实施例中，当幕布主体(201)的位置调整至幕布导轨(202)的端部时，通过在幕布导轨(202)的端部设置磁性元件(207)，能够对滑动机构(203)施加磁性力使幕布主体(201)维持在当前位置，可以避免由于车辆制动/加速所导致的幕布主体(201)的窜动。
一些可能的实现方式中，车载幕布装置(20)还可以包括线束(204)和拖链(205)。拖链(205)可以包括固定端和活动端，拖链(205)可以设置有线束轨道；线束(204)可以设置于线束轨道中，线束(204)由活动端延伸出的一端可以与幕布主体(201)连接。
本申请实施例中，通过将线束(204)设置于拖链(205)的线束轨道，能够防止幕布主体(201)移动所导致的线束(204)的扭曲/打结/损伤，有利于提升线束(204)的使用寿命。
一些可能的实现方式中，滑动机构(203)可以包括滚动件和支架(2031)。支架(2031)的一端可以连接幕布主体(2031)，支架(2031)的另一端可以连接滚动件，滚动件可以贴合于幕布导轨(202)。
本申请实施例中，通过设置滚动件，滑动机构(203与幕布导轨(202可以构成滚动导轨副，能够降低滑动机构(203)运动时的阻力，使得幕布装置(201)沿幕布导轨(202)的滑动过程更加顺畅。
一些可能的实现方式中，幕布导轨(202)的导向方向可以具有沿车辆(1)的纵轴方向的分量。
本申请实施例中，由于幕布导轨(202)的导向方向具有沿车辆的纵轴方向的分量，用户可以在车辆的纵轴方向上调整幕布主体(201)的位置，使得用户无需调整自身所在的位置就能够调整观影距离，可以提升用户的使用体验。
一些可能的实现方式中，幕布导轨(202)集成于车辆(1)的天窗框架总成(11)，可以包括：幕布导轨(202)通过紧固件与天窗框架总成(11)固定连接。
本申请实施例中，通过紧固件将幕布导轨(202)固定连接至天窗框架总成(11)，便于幕布装置(20)的维修。对于用户而言，当天窗框架总成(11)、幕布导轨(202)受损或变形时，可以仅更换其中受损或变形的零件，可以降低维修成本。对于车辆生成商而言，其所生产的多种车型可能具有不同形式的天窗、所生产的同一车型的配置可能设置有不同形式的天窗，由于幕布导轨(202)与天窗框架总成(11)为可分拆的两个装置，幕布导轨(202)可以适用于多种不同的车型、同一车型的多种配置，有利于降低幕布导轨(202)的模具与开发费用，可以提升幕布导轨(202)的通用性。
一些可能的实现方式中，幕布导轨(202)集成于车辆(1)的天窗框架总成(11)，可以包括：天窗框架总成(11)设置有能够与滑动机构(203)滑动连接的导向结构。
本申请实施例中，由天窗框架总成(11)的导向结构作为幕布导轨(201)，可以减少幕布装置的装配时间，有利于提升车辆的生产效率。
一些可能的实现方式中，幕布导轨(202)的后端可以相对于天窗框架总成(11)的后端向车辆(1)的尾部延伸。
在实际场景中，某些天窗在车辆纵轴方向上的尺寸较短，其天窗框架总成(11)的后端可能仍然处于比较靠前的位置，比如处于车辆的第一排座椅靠背附近。如果幕布导轨(202)的后端与天窗框架总成(11)平齐，幕布装置(20)可能仍然会对座舱造型的美观性有较大的劣化效果，而且幕布展开时可能会受到座椅的干扰。
本申请实施例中，通过将幕布导轨(202)的后端相对于天窗框架总成(11)的后端向车辆尾部延伸，能够降低幕布装置(20)对座舱造型美观性的劣化效果，可以避免座椅对于幕布的展开状态的干扰。
一些可能的实现方式中，天窗框架总成(11)上设置有天窗遮阳帘导轨，幕布导轨(202)可以不同于天窗遮阳帘导轨。
由于天窗遮阳帘重量较轻，天窗遮阳帘的导轨而言往往具有较低的强度、刚性，不利于承受较大的重量。本申请实施例中，将幕布导轨(202)设置为与天窗遮阳帘导轨不同的导轨，有利于保障幕布装置(20)的可靠性。
第二方面，提供了一种车辆，该车辆可以包括上述第一方面及其任一可能的实现方式中的车载幕布装置。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”以及其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”，均被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或者“一些示例(some examples)”等旨在表明与该实施例或者示例相关的特定特征、结构、材料或特性包括在本申请的至少一个实施例或者示例中。上述的术语的示意性表示不一定是指同一个实施例或者示例。此外，所述的特定特征、结构、材料或者特点能够以任何适当的方式包括在任何一个或者多个实施例或者示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或者暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多的该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是指两个或者两个以上。
下面的描述中出现的方位词均为图中示出的方向，并不是对本申请实施例中的具体结构进行限定。在本申请实施例的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或者一体地连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可视具体情况理解上述术语在本申请中的具体含义。
在本申请实施例中提及“实施例”意味着，结合实施例描述的特定特征、结构或者特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或者备选的实施例。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其它实施例相结合。
本申请中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本申请中字符“/”，一般表示前后关联对象是一种“或”的关系。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或者多个所述条件或者值的过程、步骤、计算或者其他动作在实践中可以基于额外条件或超出所述的值。
本申请实施例中所述的“约”、“大致”或“近似”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差，即测量系统的局限性所确定。
当前，对于车载幕布而言，往往固定设置于顶棚附近。在使用车载幕布时，该幕布可以在竖直方向展开形成投影区域。由于座舱内设置有座椅等装置，为了避免幕布在展开状态下受到座椅等装置的干扰，在车辆纵轴方向上，车载幕布往往设置于座椅所占用的区域之外，导致车载幕布的布置极大地受限于座舱内其他装置的分布。
而且，在实际场景中，某些车型设置有天窗，比如，可开启的手动天窗或电动天窗、可开启或不可开启的全景天窗、分段式天窗等。天窗的存在进一步加大了车载幕布的布置难度，幕布的布置方式不合理，可能会影响天窗的功能。
示例性地，图1示出了一种座舱场景的示意图。图1可以理解为用户从座舱后排观看天窗的视角。
如图1所示，车辆设置有天窗，而且幕布固定设置于车辆。对于可开启的天窗而言，车载幕布的布置方式不合理可能会影响天窗的开启与关闭。对于不可开启的全景天窗而言，如果车载幕布的布置位置不合理，以用户视角观看天窗时，车载幕布可能会将全景天窗分隔为前后两部分，对天窗、座舱的造型美观性造成较大的劣化效果，如图1所示。而且，某些车型还设置有可推拉的天窗遮阳帘，车载幕布的布置方式不合理，也可能会影响用户对于天窗遮阳帘的使用。图1所示的幕布处于收起状态；当该幕布沿竖直方向展开时，可能会受到座椅的干扰。
另外，由于车载幕布固定设置车辆上，需要依赖于用户调整自身的位置，才能够实现用户与幕布间的观影距离的调节。
鉴于此，本申请实施例提供了一种幕布装置，在车辆设置有天窗的情况下，能够满足用户的不同使用需求。
示例性地，图2是本申请实施例提供的一种天窗的布置方式的示意图。
如图2所示，车辆1可以设置有天窗框架总成11、天窗玻璃总成12、车辆的外部造型机构13、车辆的内部造型机构14。图1可以理解为在车辆1的纵轴方向上的某一截面的局部视图。为了避免雨水、灰尘等侵入车辆，天窗框架总成11、天窗玻璃总成12和/或车辆的外部造型机构13，可以包含有密封件。
天窗框架总成11(简称为天窗框架11)，可以对天窗玻璃总成12起到支撑作用。例如，对于可开启/不开启的天窗，导轨装置11可以起到支撑天窗玻璃总成12的作用。
天窗框架总成11可以包括框架111，还可以包括密封件，比如设置于框架111的密封件112、密封件113。框架111可以由一个至多个框架构件组成，比如由多个钣金件焊接/铆接/螺栓连接而成。
一些可能的实现方式中，天窗框架总成11还可以包括天窗导轨。例如，对于可开启式天窗，天窗框架总成11还可以通过天窗导轨引导天窗玻璃12的开启与关闭。
天窗玻璃总成12(简称为天窗玻璃12)可以包括玻璃板121和导流件122；还可以包括密封件123。例如，天窗玻璃12处于关闭状态下，密封件113和密封件123可以相配合，起到密封效果，防止雨水/落叶/灰尘等侵入座舱。又例如，导流件122可以与密封件132相配合，起到密封效果，防止雨水、灰尘等侵入座舱。当雨水沿导流板122和密封件132之间的缝隙流入车辆内时，在导流板122的作用下，雨水被引导至框架111。此时，框架111还可以将雨水导流至排水机构(图2未示出)，通过排水机构将雨水排出车辆外。
车辆的外部造型机构13，可以包括车身顶盖131；还可以包括密封件，比如密封件132。例如，天窗玻璃12处于关闭状态下，密封件122和密封件132可以相互配合，起到密封效果，防止雨水、灰尘等侵入座舱。
一些实施例中，密封件12、密封件113、密封件132可以为胶条。
车辆的内部造型机构14，可以构成座舱的轮廓。例如，车辆的内部造型机构14可以由一个至多个内饰板构成。
一些可能的实现方式中，车辆1还可以设置有天窗遮阳帘15，如图2所示。天窗框架总成11可以对天窗遮阳帘15起到支撑作用，还可以通过设置于天窗框架总成11的遮阳帘导轨引导遮阳帘15运动。
示例性地，图3是本申请实施例提供一种车载幕布装置的布置方式的示意图。在图3中，与图2中的装置具有相同/相似的结构和/或功能的装置，采用了与图2中相同的编号。
如图3所示，车载幕布装置20(简称为幕布装置20)可以包括幕布主体201、幕布导轨202和滑动机构203。幕布主体201与滑动机构203固定连接，滑动机构203与幕布导轨202滑动连接。
示例性地，幕布主体201可以包括，收卷辊、收卷于该收卷辊的部分或全部幕布。又例如，当幕布装置20能够沿竖直方向自动展开/收起时，幕布主体201还可以包括收卷辊的驱动机构(比如电机)。又例如，幕布主体201还可以包括用于将收卷辊传动连接至该驱动机构的传动装置等。
示例性地，幕布导轨202可以集成于天窗框架总成11。例如，可以通过铆接、焊接等工艺，将幕布导轨202与天窗框架总成11固定连接。
一个实施例中，天窗框架总成11可以包括框架111、天窗导轨等多个零件，幕布导轨202可以集成于任意零件。比如幕布导轨202可以集成于框架111、幕布导轨202可以集成于天窗导轨。
滑动机构203可以包括由一个至多个构件组成。例如，如图3所示，滑动机构203可以包括支架2031和连接杆2032。连接件2032可以耦合于支架2031。或者，连接杆2032也可以理解为是支架2031的构成件。
示例性地，支架2031可以与幕布导轨202构成滑动导轨副/滚动导轨副，使得支架2031可以在幕布导轨202的导向方向上相对于幕布导轨202移动。连接杆2032的一端可以与支架2031固定连接，连接杆2032的另一端可以与幕布主体201固定连接。
一个实施例中，以滑动导轨副为例，幕布导轨202和支架2031中的一个可以设置有凸形结构，二者中的另一个可以设置有凹型结构。该凸型结构和凹型结构可以相互配合，构成滑动导轨副，使得支架2031能够相对于幕布导轨202滑动。该场景下，支架2031可以视作能够沿导轨202滑动的滑块。
本申请实施例中，由于幕布主体201与滑动机构203固定连接，且滑动机构203与幕布导轨202滑动连接，使得幕布主体201能够在幕布导轨202的导向方向上相对于幕布导轨202移动。一方面，允许用户根据其需求调整幕布主体201的位置，可以避免幕布主体201影响用户对天窗、天窗遮阳帘的使用，使得幕布主体的布置方式可以不再受限于座舱中的座椅等装置的分布的限制。另一方面，当用户在使用幕布时，可以通过调节幕布主体的位置来调节观影距离，使得用户无需调整自身所在的位置，可以提升用户的使用体验。
而且，由于幕布导轨202集成于天窗框架总成11，使得幕布导轨202能够被车辆的内饰件遮挡，有利于降低幕布导轨202对座舱造型美观性的劣化。另外，相较于将幕布导轨202设置于车辆的其他部件(比如车架等承载装置)的方案，将幕布导轨202集成于天窗框架总成11，可以减小幕布主体201与幕布导轨间的距离，可以减小用于固定幕布主体201的滑动机构203的体积和重量，有利于降低零件成本。
一些可能的实现方式中，为了便于幕布装置20的拆卸与更换，可以通过紧固件(比如螺栓连接、螺钉连接等)将幕布导轨202固定连接至天窗框架总成11，使得幕布导轨202集成于天窗框架总成11。
本申请实施例中，通过紧固件将幕布导轨202固定连接至天窗框架总成11，便于幕布装置20的维修。对于用户而言，当天窗框架总成、幕布导轨受损或变形时，可以仅更换其中受损或变形的零件，可以降低车辆的维修成本。对于车辆生成商而言，其所生产的多种车型可能具有不同的天窗、所生产的同一车型的配置可能设置有不同形式的天窗，由于幕布导轨202与天窗框架总成11为可分拆的两个零件，幕布导轨202可以通过紧固件与不同形式的天窗的框架总成固定连接，由此能够适用于多种不同的车型、同一车型的多种配置，有利于降低幕布导轨202的模具与开发费用，可以提升幕布导轨202的通用性。
一些可能的实现方式中，天窗框架总成11可以设置有能够与滑动机构203的滑动连接的导向结构。也就是说，幕布导轨202可以耦合于天窗框架总成11，天窗框架总成11具有引导滑动机构203移动的导向结构。例如，可以通过一体成型的工艺，将天窗框架总成11与该幕布导轨202耦合为一体。
本申请实施例中，由天窗框架总成11中的导向结构作为幕布导轨201，可以减少幕布装置的装配时间，有利于提升车辆的生产效率。
示例性地，幕布导轨202的导向方向可以具有沿车辆的纵轴方向的分量。例如，幕布导轨202可以沿框架111的延伸方向设置。该框架111的延伸方向可以为车辆的纵轴方向；或者，框架111的延伸方向可以具有沿车辆的纵轴方向的分量和沿竖直方向的分量。又例如，幕布导轨202的导向方向与框架111的延伸方向可以不同，二者间可以具有夹角。
本申请实施例中，由于幕布导轨202的导向方向具有沿车辆的纵轴方向的分量，用户可以在车辆的纵轴方向上调整幕布主体201的位置，使得用户无需调整自身所在的位置就能够调整观影距离，可以提升用户的使用体验。
一些可能的实现方式中，幕布导轨202的后端相对于天窗框架总成11的后端，向车辆的尾部延伸。例如，幕布导轨202的后端可以延伸至车辆后排座椅，甚至可以延伸至车辆后端的行李舱中。
在实际场景中，某些天窗在车辆纵轴方向上的长度较小，在车辆的纵轴方向上，该天窗的框架总成11的后端可能仍然处于靠前的位置，比如处于车辆的第一排座椅靠背附近。如果幕布导轨202的后端与天窗框架总成11平齐，幕布装置20可能仍然会对座舱造型的美观性有较大的劣化效果，而且幕布展开时可能会受到座椅的干扰。
本申请实施例中，通过将幕布导轨202的后端相对于天窗框架总成11的后端向车辆尾部延伸，能够降低幕布装置20对座舱造型美观性的劣化效果，可以避免幕布在展开时受到座椅的干扰。
示例性地，幕布装置20还可以包括线束204。该线束可以用于为幕布装置20供电。例如，幕布主体201可以包括驱动收卷辊转动的电机，可以通过线束204该电机供电。又例如，幕布装置20可以包括驱动滑动机构203沿幕布导轨202的导向方向移动的电机，可以通过线束204为该电机供电。
一些可能的实现方式中，幕布装置201一侧设置有用电器，比如收卷辊的驱动电机。相应地，线束204的一端可以连接幕布主体201。线束204的另一端可以直接或间接与供电装置(比如车辆的蓄电池)电连接。为了便于说明，将线束204与用电器连接的一端称为用电端，与供电装置连接的一端称为供电端。
假设幕布主体201一侧设置有用电器。由于幕布主体201能够沿导向方向相对于幕布导轨202移动，为了对这些用电器的供电，往往需要设置较长的线束204，使得在幕布主体201处于任意位置时线束204的用电端均能够与这些用电器电连接。然而，当线束204较长时，线束204的用电端跟随幕布主体201移动时，线束204的中间部分可能会出现扭曲/打结/损伤等情况，影响线束的使用寿命。
示例性地，为避免幕布主体201移动所导致的线束204的扭曲/打结/损伤，幕布装置20可以设置拖链205(也可以称为坦克链205)。拖链205可以包括固定端和活动端，拖链205可以包括用于设置线束的线束轨道。例如，拖链205的固定端可以与车辆固定连接，使其相对于车辆静止；线束204由拖链205的固定端延伸出的部分，可以与车辆的供电装置电连接。又例如，线束204由拖链205的活动端延伸出的部分，可以经由车辆的内饰机构14与天窗框架总成11之间的空隙连接至幕布主体201，如图2所示。
示例性地，图4是本申请实施例提供的一种拖链的结构示意图。
如图4所示，拖链205可以由多个构件2051构成。例如，构件2051两侧的侧板、上顶板和下底板所合围而成的容纳空间，可以构成线束轨道，以约束处于该容纳空间中的线束的姿态。又例如，相邻构件2051之间可以相互卡接并构成转动副，使得相邻的构件2051能够在一定角度范围内相对转动。当线束204的用电端跟随幕布主体201移动时，拖链205的形状将发生改变。
上述图4所示的拖链结构仅为示例，还可以使用其他形式的拖链，本申请实施例对此不做限定。
本申请实施例中，通过将线束204设置于拖链205的线束轨道，能够防止幕布主体201移动所导致的线束204的扭曲/打结/损伤，有利于提升线束的使用寿命。
一些可能的实现方式中，拖链205的弯曲半径大于或等于第一阈值。比如该第一阈值为25毫米、30毫米，或者，也可以根据线束的具体尺寸确定该第一阈值。
由于幕布主体201能够相对于幕布导轨202在其导向方向上移动，当不使用幕布时，用户可能会倾向于将幕布主体201调节至幕布导轨202的端部，以避免其影响天窗、天窗遮阳帘等部件的使用。当需要使用幕布时，用户会将其调节至所需的位置，使得幕布在竖直方向上展开形成投影区域。
一些可能的实现方式中，幕布导轨202的端部可以设置有磁性元件，磁性元件可以用于：滑动机构处于该导轨的端部时，磁性固定滑动机构。例如，可以在幕布导轨202的前端和/或后端设置磁铁；滑动机构203可以由铁磁性材料制成，或者可以设置有铁磁性材料的构件，使得磁铁能够对滑动机构提供磁性力。
本申请实施例中，当幕布主体201的位置调整至幕布导轨202的端部时，通过对滑动机构203施加磁性力，可以使幕布主体201维持在当前位置，可以避免由于车辆制动/加速所导致的幕布主体201的窜动。
上述图3仅示出了幕布主体201的某一端的结构及对应的导轨202。例如，在幕布主体201的另一端，幕布装置20可以具有图3所示结构的对称结构，也可以设置有对应的导轨。又例如，一些可能的实现方式中，幕布主体201的另一侧甚至可以悬空。
一些实施例中，幕布主体201的两侧均可以设置有导轨202、滑动机构203等。为便于区分，可以采用后缀“-1”、“-2”区分处于幕布主体201左右两侧的部件。例如，可以将左右两侧的幕布导轨202分别记作导轨202-1、导轨202-2。又例如，幕布主体201的一端可以通过连接杆2032-1与支架2031-1固定连接，支架2031-1可以与导轨202-1构成滑动导轨副/滚动导轨副；幕布主体201的另一端可以通过连接杆2032-2与支架2031-2固定连接，支架2031-2可以与导轨202-2构成滑动导轨副/滚动导轨副。
一些可能的实现方式中，幕布装置20还可以包括制动机构206。制动机构206可以用于，在制动状态下，维持幕布主体201与幕布导轨202间的相对位置不变。
本申请实施例中，通过设置制动机构，幕布主体201可以维持在当前位置而不会沿幕布导轨202移动，可以避免在使用幕布时幕布主体201沿幕布导轨窜动而影响用户的观影体验。
一些可能的实现方式中，制动机构206可以包括开关2061、传动件2062、弹性件2063和制动块2064。弹性件2063可以用于在制动状态下提供制动块2064贴合与幕布导轨202的压力。传动件2062可以将制动块2064传动连接至开关2061；其中，开关2061在第一方向上的移动带动制动块2062在第二方向上的运动，以使制动机构206处于制动状态或解除制动状态。例如，可以通过静摩擦力、卡接结构等方式，使得制动块2064与幕布导轨202相对静止，使得幕布主体201处于制动状态。又例如，弹性件2063形变所产生的弹力，可以直接作用于制动块2064；或者，该弹力也可以作用于传动件2062，传动杆2063可以将传递给制动块2064，使得弹性件2063可以提供制动块2064贴合于幕布导轨202的压力。
以下结合图5至图7，对传动件2062、弹性件2063以及制动块2064的作动方式做示例性说明。
示例性地，图5是本申请实施例提供的一种制动机构的结构示意图。
如图5所示，传动件2062可以沿轴2065转动。例如，传动件2062可以为拉杆，或者，也可以由多个连接杆构成。
以左侧的制动块2064-1为例，简要说明制动机构206的工作方式。
当用户未按压开关2061时，制动机构206可以处于制动状态。此时，弹性件2063-1可以处于压缩状态。由于传动件2062-1可以绕轴2065-1转动，弹性件2063-1作用于传动件2062-1的压力，可以转化为制动块2064-1贴合于幕布导轨202-1的压力。由此，弹性件2063-1可以提供制动块2064-1贴合于幕布导轨202-1的压力。
当用户按压开关2061时，开关2061沿方向1运动，传动件2062-1沿轴2065-1转动，进而带动制动块2064-1转动。制动块2064-1转动时，有沿方向2的分量。用户按压开关2061的过程中，制动块2064-1施加于导轨202-1的压力可以逐渐衰减，直至制动块2064-1不再贴合于导轨202-1。当用户松开开关2061时，由于弹簧2063-1依然处于压缩状态，弹性件2063-1可以向传动件2062-1施加压力，开关2061将会沿方向1运动恢复至其初始位置，制动块2064-1将会沿方向2运动直至贴合于导轨202-1。
示例性地，图6是本申请实施例提供的另一种制动机构的结构示意图。以依然以左侧的制动块2064-1为例，简要说明制动机构206的工作方式。
在图6所示方案中，当用户未按压开关2061时，弹性件2063-1可以处于拉伸状态。弹性件2063-1作用于传动件2062-1的拉力，可以转化为制动块2064-1贴合于幕布导轨202-1的压力，使得制动机构206能够处于制动状态。
与图5所示方式类似，当用户按压开关2061时，开关2061沿方向1运动将带动制动块2064-1在方向2上运动。用户按压开关2061的过程中，制动块2064-1施加于导轨202-1的压力可以逐渐衰减，直至制动块2064-1不再贴合于导轨202-1。当用户松开开关2061时，在弹性件2063-1的拉力的作用下，开关2061将会沿方向1运动恢复至其初始位置，制动块2064-1将会沿方向2运动直至贴合于导轨202-1。
示例性地，图7是本申请实施例提供的另一种制动机构的结构示意图。
与图5、图6所示方式不同，如图7所示，弹性件2063的一端可以直接于制动块2064连接。弹性件2063可以直接向制动块2064提供使其贴合于幕布导轨202的压力。图5至图7的虚线，可以理解为幕布装置20中用于遮挡制动机构206的内部结构的壳体。
本申请实施例中，通过设置弹性件2063，制动机构206能够在无需用户操作的情况下，将幕布主体201维持于当前位置；通过设置传动件2062，能够以比较简单的结构使得制动机构206进入和解除制动状态，有利于简化制动机构的结构。
以下结合图8，对制动块2064与导轨202间的贴合方式作示例性说明。
示例性地，图8是本申请实施例提供的制动块2064与导轨202的贴合方式的示意图。在图8中，制动块2064可以对应于图5至图7中的制动块2064-1或2064-2；相应地，在图8中，幕布导轨202可以对应于图5至图7中的幕布导轨202-1或202-2。
一个实施例中，幕布导轨202上用于与制动块2064贴合的面，可以为平面。例如，如图8所示的贴合方式1。
又一个实施例中，在幕布导轨202与制动块2064的贴合面上，幕布导轨202和制动块2064可以分别设置有凹型结构和凸型结构。例如，如图8所示的贴合方式2。
本申请实施例中，贴合面所设置有相互匹配的凹型结构和凸型结构时，即使对制动块2064施加较小的压力，制动机构206仍然能够实现较好的制动效果。也就是说，采用较小弹性系数的弹性件2063就能够实现较好的制动效果。该场景下，由于弹性件2063的弹性系数较小，当用户按压开关2061时将会受到的较小的抵抗力，通过该方式，可以减少用户对于开关2061作动不灵敏的抱怨。
一些可能的实现方式中，滑动机构203可以包括支架2031和滚动件，支架2031的一端与幕布主体201连接，支架2031的另一端可以连接滚动件，滚动件设置于幕布导轨202内。
假设上述滚动件为滚珠，以下结合图9对滑动机构203的结构作示例性说明。
示例性地，图9是本申请实施例提供的一种滑动机构203的结构示意图。图9中的(a)至(c)可以理解为滑动机构203的不同视角。比如，图9中的(a)可以理解为滑动机构203的侧视图；图9中的(b)可以理解为滑动机构203的正视图；图9中的(c)可以理解为滑动机构203的俯视图。图9中的(b)所采用的视角，可以与图3所采用的视角相同。
在图9中，幕布导轨202上的不同的面，可以分别记作面202a至面202c。如图9所示，某一滚珠可以与面202a或面202b接触。支架2031可以设置有容纳滚珠的结构，可以通过弹簧为滚珠提供压力，由此滚珠可以贴合于幕布导轨202。支架2031可以支持设置一排至多排滚珠。例如，支架2031可以通过连接件2032与幕布主体201连接。一些实现方式中，连接件2032可以耦合于支架2031，即二者可以为同一个零件。
在图9所示方案中，导轨202的多个面202a至202c构成空腔，滑动机构203可以设置于该空腔中。一些可能的实现方式中，与图9所示方式不同，滑动机构203的多个面可以构成空腔，导轨202可以设置于该空腔中。
图9所示的滚珠，可以作为滑动机构203中的滚动件的一个示例。在该场景下，通过滚珠，滑动机构203和幕布导轨202可以构成滚珠导轨副。一些可能的实现方式中，滑动机构203中的滚动件可以为滚针、滚珠；相应地，滑动机构203和幕布导轨202可以构成滚针导轨副、滚珠导轨副。本申请实施例对该滚动件的具体类型不作限定。
本申请实施例中，通过设置滚动件，滑动机构203与幕布导轨202可以构成滚动导轨副，能够降低滑动机构203与幕布导轨202之间的摩擦力，使得幕布装置201沿幕布导轨202的运动更为顺畅。
假设制动机构206采用如图5所示的结构，且滑动机构203采用如图9所示结构。以下结合图10介绍幕布装置20中的构成件之间的相对位置关系。
示例性地，图10是本申请实施例提供的幕布装置的多个构成件间的相对位置关系的示意图。图10中的(a)和(b)，采用了与图9中的(a)相同的视角；图10中的(c)所采用的视角，与图9中的(c)的视角相同。
一个实施例中，如图10中的(a)所示，导轨202的端部可以设置有磁性元件207(比如磁铁)，当滑动机构203移动至导轨202的端部时，磁性元件207可以磁性固定该滑动机构203。通过该方式，可以避免滑动机构203在车辆行驶过程中沿幕布导轨202窜动。
又一个实施例中，如图10中的(b)和(c)所示，在幕布导轨202的导向方向上，滑动机构203和制动机构206可以并列设置。滑动机构206中除传动件2062和制动块2064以外的其他构件，并未在图10的(b)和(c)中示出。
又一个实施例中，制动机构206也可以集成于滑动机构203。例如，连接杆2032中设置有通孔，传动件2062可以设置于该通孔中；支架2031可以设置有通孔，制动块2064可以设置于该通孔中，且能够在该通孔中活动。通过该方式，可以减小幕布装置20所占用的体积。
一些可能的实现方式中，当天窗框架总成11设置有天窗遮阳帘的导轨时，由于天窗遮阳帘重量较轻，天窗遮阳帘的导轨往往具有较低的强度、刚性，不利于承受较大的重量。幕布导轨202与该天窗遮阳帘的导轨应为不同的导轨。甚至，当集成于天窗框架总成11时，幕布导轨202应当集成于天窗遮阳帘导轨之外的其他位置，以保证幕布装置20的可靠性。
本申请实施例还提供了一种天窗框架总成，该天窗框架总成集成有图3至图10中任一一种方案下的幕布导轨202，该幕布导轨202用于与滑动机构203滑动连接，该滑动机构203与幕布主体201固定连接。
本申请实施例还提供了一种车辆，该车辆可以包括上述图3至图10中任一一种的车载幕布装置20。
