一种具有悬停功能的车用遮挡帘以及车辆

Abstract

本实用新型提供了一种具有悬停功能的车用遮挡帘以及车辆，属于车用零部件技术领域，包括：滑槽支架，滑槽支架设置有齿条；滑动板的两侧均设置有齿轮，两个齿轮分别与两个滑槽支架的齿条啮合；齿轮通过一单向锁止件形成单向转动结构。本实用新型的有益效果为：单向锁止件能够与齿轮耦合或者解耦，两者耦合时使齿轮形成单向转动结构，使得滑动板只能沿伸展方向滑动；而单向锁止件与齿轮解耦时，滑动板能够沿伸展方向或者回缩方向滑动，由于遮挡帘的悬停功能是通过单向转动的齿轮与齿条配合实现的，所以其对于遮挡帘的安装位置以及帘布的伸缩方向没有限制使得遮挡帘具有极强的通用性以及灵活性。

The reset drive is connected to the roller tube (810), and the reset drive applies a pulling force to the sliding plate (200) through the roller tube (810) and the curtain fabric (820) to make it tend to move in the retraction direction.

3. The vehicle sunshade with hovering function according to claim 1, wherein: The sliding plate (200) is provided with a slidable unlocking mechanism. The one-way locking member is connected to the unlocking mechanism or the one-way locking member is located on the unlocking mechanism. The unlocking mechanism has a locked state and an unlocked state. When the unlocking mechanism is in the locked state, the one-way locking member is coupled to the gear (300). When the unlocking mechanism is in the unlocked state, the one-way locking member is decoupled from the gear (300).

4. The vehicle sunshade with hovering function according to claim 3, wherein: The unlocking mechanism includes an unlocking block (400) and two control rods (500). The unlocking block (400) and the two control rods (500) are slidably connected to the sliding plate (200). The unlocking block (400) is linked to the two control rods (500). The stroke position of the unlocking block (400) determines the stroke position of the two control rods (500). When the unlocking block (400) slides, it simultaneously drives the two control rods (500) to slide, and the two control rods (500) slide in opposite directions. The two control rods (500) are respectively connected to the two one-way locking members, or the two one-way locking members are respectively located on the two control rods (500).

5. A vehicle-mounted sunshade with a hovering function as described in claim 4, characterized in that: The unlocking block (400) is provided with two driving inclined surfaces (410), and the control rod (500) is provided with a force-receiving inclined surface (510). The two driving inclined surfaces (410) on the unlocking block (400) are respectively attached to the force-receiving inclined surfaces (510) of the two control rods (500) to form an inclined surface driving structure. The travel positions of the unlocking block (400) include a locked position and an unlocked position; when the unlocking block (400) is in the locked position, the one-way locking member is coupled to the gear (300) through the control rod (500); when the unlocking block (400) is in the unlocked position, the one-way locking member is decoupled from the gear (300) through the control rod (500).

The locking spring (420) applies a spring force to the unlocking block (400) to make it tend toward the locked position.

7. A vehicle sunblind with hovering function as claimed in claim 5 or 6, characterized in that: The sliding plate (200) is provided with a handle hole (210), and the unlocking block (400) is located in the handle hole (210).

8. The vehicle sunshade with hovering function according to claim 4, wherein: The one-way locking component is a clamping spring (600).
