Definitions

  • the present application relates to the field of vehicle technology, and in particular to a roller assembly, a sunshade assembly and a vehicle.
  • the reel assembly of the existing sunshade is usually composed of two springs (as shown in Figure 1).
  • the sunshade is manually opened, the pull cord wound on the wire wheel is released, the fabric at the pull rod is recovered, the side strip is recovered, and the inner tube follows.
  • the wire wheel at the end of the reel rotates in the same direction as the inner tube and the same length.
  • the spring inside the reel has no relative displacement relative to the inner tube and the wire wheel, and the force balance is always maintained.
  • the sunshade remains stationary.
  • the sunshade is closed, the wire wheel will reel in the pull cord in the opposite direction and the same force, thereby realizing the function of pulling and stopping.
  • the reel assembly in Figure 1 uses two springs to apply reeling force to the wire wheel respectively.
  • the two springs are subject to processing and assembly errors, and the reeling force is easily inconsistent, which may cause the curtain to get stuck when the pull rod pulls the curtain.
  • the two reeling mechanisms are subjected to different forces, resulting in inconsistent movements at both ends of the curtain, which in turn causes the sunshade to get stuck and tilted.
  • Patent document: CN208812942U discloses a sunshade, in which a single spring is used to solve the above-mentioned problems.
  • the two ends of the spring are respectively connected to the fixed block and the winding wheel; in the reel assembly of Figure 1, one end of the spring is also directly connected to the wire wheel. Since the spring is in a stretched state, the spring generates axial tension, which pulls the wire wheel toward the reel. The position of the wire wheel is affected by the length of the reel. If the reel is too short, the wire wheel will move axially when the reel and the wire wheel rotate, which can easily cause eccentric wear of the pull cord and reduce the service life of the sunshade.

相关申请
本申请要求于2023年09月11日递交的申请号为202311165283.0的中国专利申请的优先权，并引用上述专利申请公开的内容作为本申请的一部分。
技术领域
本申请涉及车辆技术领域，尤其涉及一种卷轴总成、遮阳帘总成及车辆。
背景技术
目前现有汽车遮阳帘中，为了随心所欲地控制遮蔽面积，满足使用者的需求，一般开发出许多具有随拉随停功能的遮阳帘，现有的遮阳帘的卷轴总成通常由两根弹簧组成(如图1所示)，当手动打开遮阳帘时，缠绕在线轮转动的拉绳放出，拉杆处的面料回收，边条回收，内管随动，卷轴端线轮与内管转动方向一致，转动长度相同，卷轴内弹簧相对于内管和线轮无相对位移，始终保持力平衡，停止施力时，遮阳帘保持静止。关闭遮阳帘时，线轮又会卷入拉绳，方向相反，受力相同，以此实现随拉随停功能。
图1中的卷轴总成使用两根弹簧分别对所述线轮施加卷收力，两根弹簧受到加工及装配误差，卷收力度容易不一致，导致拉杆拉动帘布的过程中易造成卡滞；因卷轴总成的两端为两套独立的卷收机构，当拉动位置偏离拉杆中心时，两套卷收机构受力不同，导致帘布的两端动作不一致，进而造成遮阳帘卡滞倾斜。
专利文件：CN208812942U公开了一种遮阳帘，其中使用单弹簧来解决上述提到的问题，但是在该专利文件中，该弹簧的两端分别连接在固定块和绕线轮上；图1的卷轴总成中，弹簧的一端也与线轮直接相连。由于弹簧处于拉伸状态，弹簧产生轴向张力，该轴向张力会把线轮拉向卷轴。线轮位置受卷轴长度影响，若卷轴太短，卷轴和线轮转动时，线轮会在轴向窜动，易造成拉绳偏磨，降低遮阳帘的使用寿命。

具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似改进，因此本申请不受下面公开的具体实施例的限制。
如图2-3所示，本申请在一些实施例中，提供了一种卷轴总成10，包括：
内管11；
连接杆12，可转动的内嵌并贯穿于内管11；
两个线轮13，分别设置于连接杆12的两端并且位于内管11的外侧；两个线轮13与连接杆12在连接杆12的旋转方向上固定连接，两个线轮13与连接杆12在连接杆12的轴向上活动连接；
弹簧固定座141，设置于内管11与连接杆12之间且固定于内管11的一端，弹簧固定座141与连接杆12在连接杆12的轴向方向上活动连接；
弹簧固定轴142，固定于连接杆12且位于内管11的内部；
弹簧14，卷绕在连接杆12上，弹簧14的一端固定于弹簧固定座141，弹簧14的另一端固定于弹簧固定轴142；以及
两个卷轴支座15，分别设置于连接杆12的两端并且位于线轮13的外侧；弹簧14具有轴向张力使得两个线轮13在连接杆12的轴向方向上被向外推动至两个卷轴支座15。
安装时，弹簧14卷绕在连接杆12上，弹簧14的一端固定于弹簧固定座141，弹簧14的另一端固定于弹簧固定轴142；连接杆12带着弹簧14穿过内管11，弹簧固定座141固定在内管11的一端；推动连接杆12，连接杆12的另一端穿过内管11的另一端，使弹簧14处于拉伸状态，弹簧14产生轴向张力，由于两个线轮13与连接杆12在连接杆12的轴向上活动连接并且弹簧固定座141与连接杆12在连接杆12的轴向方向上活动连接，该轴向张力分别通过连接杆12和弹簧固定座141将设置于连接杆12两侧的线轮13向外侧推至卷轴支座15，避免了内管11和线轮13转动时在自身轴向窜动造成拉绳27偏磨的现象，提升了线轮13的位置准确度，降低了内管11的尺寸加工精度，提高了遮阳帘总成20的使用寿命；
在本实施例中，弹簧14为卷簧或扭簧。弹簧14经过预旋后再安装入卷轴总成10，弹簧14经过预旋后产生的卷收力能够绷紧卷绕在卷轴总成10上的帘布25，保证帘布25在打开或者关闭的过程中始终处于绷紧状态，避免其向中部下垂，同时还能够防止褶皱的产生。
通过一根弹簧14同时对两个线轮13施加卷收力，由于两个线轮13与连接杆12在连接杆12的旋转方向上固定连接，且卷收力只由一根弹簧14提供，故两个线轮13的卷收力始终相同。解决了背景技术中卷轴总成采用两根弹簧(如图1所示)可能出现的弹性系数不一致从而导致两个线轮的卷收力不一致的问题。
在本实施例中，可选地，如图7所示，线轮13为圆柱形，或者，如图8所示，线轮13为锥形。
在本实施例中，进一步地，内管11、连接杆12、线轮13以及弹簧14同轴设置，以保证卷轴总成10的运行稳定性，避免出现噪音。
在本实施例中，进一步地，如图2所示，卷轴总成10还包括固定轴套16，固定轴套16设置于内管11与连接杆12之间且固定于内管11的的另一端；连接杆12可转动地安装在固定轴套16内。固定轴套16的设置能够避免连接杆12在内管11中发生位移使两个线轮13的轴线偏移从而导致拉动帘布25时出现卡顿的现象。
在一种实施例中，如图3所示，连接杆12与弹簧14之间设有内套管17。内套管17的设置能够防止弹簧14与连接杆12摩擦产生异响。
在一种实施例中，如图3所示，弹簧14与内管11之间设有外套管18。外套管18的设置能够防止弹簧14与内管11摩擦产生异响。
同时，如图4所示，本申请还提供了一种遮阳帘总成20，包括：
玻璃21；
如上的卷轴总成10；卷轴总成10固定于玻璃21；
两个导轨22，平行设置于玻璃21的两侧；每个导轨22的一端与对应侧的线轮13对齐；
拉杆23，拉杆23与卷轴总成10相对间隔设置，拉杆23的两端分别设置滑块24；滑块24包括相连的安装部241和滑动部242，安装部241固定于拉杆23，滑动部242可滑动地安装在对应侧的导轨22内；
帘布25，帘布25的一端卷绕在内管11上，帘布25的另一端与拉杆23连接，帘布25的两个侧边分别设置在对应侧的导轨22内；
两个滑轮26，每个滑轮26设置于对应侧的导轨22的另一端；
两个拉绳27，每个拉绳27的一端卷绕于对应侧的线轮13，每个拉绳27的另一端经过对应侧的滑轮26换向后固定于对应侧的滑动部242；以及
驱动机构28，设置于拉杆23或卷轴总成10。
弹簧14经过预旋后再安装入卷轴总成10，弹簧14经过预旋后产生卷收力作用在帘布25上，滑块24和卷轴总成10通过拉绳27、线轮13和滚轮来改变力的方向，使帘布25的卷收力在滑块24上达到力的平衡，帘布25能够在任意位置停留，实现遮阳帘总成的随拉随停功能。并且，弹簧14经过预旋后产生的卷收力能够绷紧卷绕在卷轴总成10上的帘布25，保证帘布25在打开或者关闭的过程中始终处于绷紧状态，避免其向中部下垂，同时还能够防止褶皱的产生。
通过一根弹簧14同时对两个线轮13施加卷收力，由于两个线轮13与连接杆12在连接杆12的旋转方向上固定连接，且卷收力只由一根弹簧14提供，故两个线轮13的卷收力始终相同。当驱动机构28驱动拉杆23拉动帘布25的一侧时，该侧的滑块24会拉动该侧的拉绳27，该侧的拉绳27通过该侧的滑轮26拉动该侧的线轮13，该侧的线轮13转动，同时，另一侧的线轮13亦随之转动，另一侧的线轮13带动另一侧的拉绳27，另一侧的拉绳27连接另一侧的滑块24，另一侧的滑块24连接拉杆23，使得拉杆23拉动帘布25的另一侧，帘布25的两侧同时进行同向动作，保证了帘布25的运动一致性。因此，无论拉杆23拉动帘布25的哪一侧，帘布25的两侧都能够共同运动，解决了拉杆受力不均时，帘布两侧运动不一致，拉杆倾斜，导致帘布卡在导轨内无法继续运行的问题。
在本实施例中，玻璃21的材料不限，通常为无机玻璃或者有机玻璃，亦或是复合材料；导轨22的材料不限，通常为塑料或金属材质。
在本实施例中，可选地，驱动机构28为手动驱动机构或电机驱动机构，可以通过手动和 自动两种方式实现帘布25的打开和关闭。
进一步地，如图4所示，手动驱动机构28为设置在拉杆23上的把手281。
在一种实施例中，如图6-8所示，拉绳27包括固定于线轮13的端头件271，线轮13具有相对的第一侧131和第二侧132，线轮13的第一侧131设有与端头件271的形状相吻合的卡槽133，端头件271固定于卡槽133；线轮13还设有用于容纳拉绳27的线槽134，拉绳27从线轮13的第二侧132卷绕到线槽134上。
端头件271设置在位于线轮13的第一侧131的卡槽133中，拉绳27从线轮13的第二侧132卷绕到线槽134上，端头件271的位置与拉绳27开始在线轮13的线槽134上卷绕的位置为不同侧，与二者设置在同侧相比，增强了线轮13与拉绳27的固定效果，解决了与线轮连接的拉绳的端头件容易脱离线轮从而导致拉绳缠绕失效的问题。
在一种实施例中，如图9-10所示，帘布25的两个侧边均设有边条251，边条251固定于滑动部242，边条251和滑动部242均与导轨22滑动配合。
在本实施例中，边条251与滑动部242的固定方式不做限定，边条251可通过粘接等方式固定于滑动部242；滑动部242与边条251连接，加强了对边条251的固定效果，便于引导边条251进入导轨22。
在本实施例中，边条251可采用TPV、TPE、TPEE等塑料材料，也可采用钢带边条和PDF边条。可选地，边条251的材料为塑料。塑料边条具有摩擦系数小，易卷收弯曲，柔韧性能好等优点，能够减轻帘布25在运行过程中的阻力，提升帘布25在遮阳帘总成20中的运行稳定性。
同时，本申请还提供了一种车辆，包括如上的遮阳帘总成20。
上述的车辆，通过使用如上的遮阳帘总成20，弹簧14处于拉伸状态产生的轴向张力使得两个线轮13在其轴向方向上分别被连接杆12和弹簧固定座141向外推动至两个卷轴支座15，避免了内管11和线轮13转动时在自身轴向窜动造成拉绳27偏磨的现象，提升了线轮13的位置准确度，降低了内管11的尺寸加工精度，提高了遮阳帘总成20的使用寿命；其次，弹簧14预旋后的产生的卷收力能够绷紧卷绕在卷轴总成10上的帘布25，保证帘布25在打开或者关闭的过程中始终处于绷紧状态，避免其向中部下垂，同时还能够防止褶皱的产生；再次，通过一根弹簧14同时对两个线轮13施加卷收力，且两个线轮13在连接杆12的旋转方向上与连接杆12刚性连接，保证了帘布25的运动一致性。因此，无论拉杆23拉动帘布25的哪一侧，帘布25的两侧都能够共同运动，解决了拉杆受力不均时，帘布两侧运动不一致，拉杆倾斜，导致帘布卡在导轨内无法继续运行的问题；最后，避免拉绳从线轮端脱落； 滑块24的滑动部242与边条251连接，加强了对边条251的固定效果，便于引导边条251进入导轨22。
