通过这种方式，不仅可以将轴杆803与传动件801进行连接，而且可保证驱动装置本体805对挡光板806推拉，挡光板806沿旋转轴807做旋转运动时，轴杆803可以沿第二导轨802自由滑动，避免切换过程出现结构干涉与卡死。具体地，当驱动装置本体805驱动轴杆803时，轴杆803直线或旋转带动传动件801，具体地，挡光板806在轴杆803前端导球804的带动下进行偏转，此时导球804会在导槽中上下滑动，不会被受限卡住；当驱动装置本体805停止对轴杆803驱动时，轴杆803复位，导球804同样可以带动挡光板806回复到原位置。In this way, not only the shaft 803 can be connected with the transmission member 801, but also the drive device body 805 can be pushed and pulled against the light blocking plate 806. When the light blocking plate 806 is rotated along the rotation axis 807, the shaft 803 can be moved along the second The guide rail 802 slides freely to avoid structural interference and seizure during the switching process. Specifically, when the driving device body 805 drives the shaft 803, the shaft 803 drives the transmission member 801 linearly or rotationally. Specifically, the light blocking plate 806 is deflected by the guide ball 804 at the front end of the shaft 803. At this time, the guide ball 804 is deflected. It will slide up and down in the guide groove, and will not be caught by the restriction. When the driving device body 805 stops driving the shaft 803, the shaft 803 is reset, and the guide ball 804 can also drive the light blocking plate 806 to the original position.
当然，在其它实施例中，还可以采用其它方式实现轴杆与传动件的连接，如，可以将轴杆与传动件直接进行固定连接，等等。Of course, in other embodiments, the shaft can be connected to the transmission member in other ways, for example, the shaft can be directly fixedly connected to the transmission member, and so on.
可选地，继续参见图1至图3，本实施例车灯的灯光切换装置101进一步包括扭簧103，扭簧103套设在转动轴105上，扭簧103的一端连接在挡光板106上，扭簧103的另一端连接在底座102上。Optionally, continuing to refer to FIGS. 1 to 3, the lamp switching device 101 of this embodiment further includes a torsion spring 103, which is sleeved on the rotating shaft 105, and one end of the torsion spring 103 is connected to the light blocking plate 106. The other end of the torsion spring 103 is connected to the base 102.
驱动装置本体108断电时，轴杆109在驱动装置本体108内置弹簧的作用下收缩，扭簧103进一步地带动传动件107沿第二方向旋转，传动件107带动挡光板106从第二位置回旋至第一位置，以增加挡光板106对光束的遮挡角度。When the driving device body 108 is powered off, the shaft 109 contracts under the action of the built-in spring in the driving device body 108. The torsion spring 103 further drives the transmission member 107 to rotate in the second direction, and the transmission member 107 drives the light blocking plate 106 to rotate from the second position. To the first position to increase the blocking angle of the light blocking plate 106 to the light beam.
本实施例的扭簧103可以有效弥补驱动装置104内置弹簧回复力不足，增强灯光切换的灵敏性。The torsion spring 103 in this embodiment can effectively make up for the insufficient spring restoring force of the built-in spring of the driving device 104 and enhance the sensitivity of light switching.
在一应用场景中，当驱动装置本体108不对轴杆109驱动时，即驱动装置本体108不通电时，挡光板106在扭簧103的预留压缩扭矩的作用下稳定的处于第一位置，形成近光分布。当驱动装置本体108通电时，轴杆109会在驱动装置本体108的驱动下运动，轴杆109前端的第一连杆601及第二连杆602会带动第一导轨503一起运动，使得挡光板106摆到第二位置，形成远光分布。当驱动装置本体108通电中断的瞬间，驱动装置本体108的内置弹簧可拉动轴杆109带动挡光板106回到第一位置，同时，扭簧103的扭力也能帮助挡光板106回到第一位置。In an application scenario, when the driving device body 108 does not drive the shaft 109, that is, when the driving device body 108 is not energized, the light blocking plate 106 is stably in the first position under the action of the reserved compression torque of the torsion spring 103, forming Low beam distribution. When the driving device body 108 is powered on, the shaft 109 will move under the driving of the driving device body 108. The first link 601 and the second link 602 at the front end of the shaft 109 will move the first guide rail 503 together, so that the light blocking plate 106 swings to the second position to form a high beam distribution. When the power of the driving device body 108 is interrupted, the built-in spring of the driving device body 108 can pull the shaft 109 to bring the light blocking plate 106 back to the first position. At the same time, the torsion spring 103 can also help the light blocking plate 106 return to the first position. .
当然，在其它实施例中，可仅通过扭簧103的扭力使挡光板106回到第一位置。Of course, in other embodiments, the light blocking plate 106 can be returned to the first position only by the torsion of the torsion spring 103.
可选地，本实施例车灯的灯光切换装置101进一步包括挡光板压片111，挡光板压片111用于将挡光板106的转动轴104固定于底座102上。具体地，挡光板压片111包括上压片112及下压片113，下压片113固定在底座102上，先将转动轴105扣合在上压片112与下压片113间，然后通过螺钉(图未标)将上压片112固定在下压片113上。Optionally, the light switching device 101 of the vehicle light in this embodiment further includes a light blocking plate pressing piece 111, and the light blocking plate pressing piece 111 is used to fix the rotation shaft 104 of the light blocking plate 106 on the base 102. Specifically, the light blocking plate pressing piece 111 includes an upper pressing piece 112 and a lower pressing piece 113. The lower pressing piece 113 is fixed on the base 102, and the rotating shaft 105 is first fastened between the upper pressing piece 112 and the lower pressing piece 113, and then passes through. The screws (not shown) fix the upper pressing piece 112 on the lower pressing piece 113.
本实施例采用两个挡光板压片111分别将转动轴105的两端固定在底座102上。在其它实施例中，不限定挡光板压片的数量。In this embodiment, two light blocking plate pressing pieces 111 are used to respectively fix two ends of the rotating shaft 105 on the base 102. In other embodiments, the number of the light blocking platen is not limited.
本实施例的挡光板压片111结构不仅能够为扭簧103提供一定的空间，而且能够提高旋转轴105旋转的灵活性。The structure of the light blocking plate pressing piece 111 in this embodiment can not only provide a certain space for the torsion spring 103, but also can improve the flexibility of the rotation of the rotating shaft 105.
当然，在其它实施例中，还可以采用其它固定件将挡光板的转动轴固定于底座上，例如，直接通过螺钉将转动轴固定于底座上，等等。Of course, in other embodiments, other fixing members may also be used to fix the rotation shaft of the light blocking plate to the base, for example, directly fixing the rotation shaft to the base by screws, and so on.

此外，本申请实施例的挡光板沿旋转轴做旋转运动时，第一导轨可以在第一连杆及第二连杆间自由滑动，避免切换过程出现结构干涉与卡死。In addition, when the light blocking plate in the embodiment of the present application performs a rotational movement along the rotation axis, the first guide rail can slide freely between the first link and the second link to avoid structural interference and seizure during the switching process.
进一步地，本申请实施例通过扭簧能够增加挡光板的回复力，有效提高灯光切换的灵敏性。Further, in the embodiment of the present application, the torsion spring can increase the restoring force of the light blocking plate and effectively improve the sensitivity of light switching.
