Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

1-8, the present embodiment provides a sun visor for an automobile, including a sun visor body 2 and a base 1, the base 1 is connected with the front beam 4 of the roof of the automobile, and the sun visor body 2 and the base 1 are connected by a rotating shaft 3 Hinged, one side of the sun visor body 2 is provided with a mirror frame 11, the mirror frame 11 is provided with a lens, the mirror frame 11 is slidably connected with a mirror cover 12 covering the lens, and the mirror frame 11 and the mirror cover 12 are in a sliding manner The connection can slow down the shaking of the mirror cover 12 during the driving of the vehicle, and at the same time, the exposed area of the mirror can be adjusted, which is more in line with the needs of users.

6 to 7 , a first buffer device 111 is provided at the sliding connection between the mirror frame 11 and the mirror cover 12 , and the first buffer device 111 is used to apply a certain amount of pressure to the mirror cover 12 during the sliding process of the mirror cover 12 . Therefore, the sliding process of the mirror cover 12 is buffered, so that the sliding process of the mirror cover 12 is more stable, and shaking and noise are reduced.

Referring to FIG. 8 , the sun visor body 2 is also provided with a second buffer device 28 for buffering the mirror cover 12 when the mirror cover 12 slides to the end of the stroke (the mirror cover 12 is in a fully opened state). The second buffer device 28 When the mirror cover 12 slides to the end of the stroke, a certain damping force can be applied to the mirror cover 12 to avoid the free sliding end of the mirror cover 12 when the mirror cover 12 is fully opened (the end perpendicular to the sliding connection end of the mirror cover 12) ) and the sun visor body 2 generate a large impact force, which has a better shock absorption effect, thereby reducing the instantaneous shaking of the mirror cover 12 and reducing noise.

In one embodiment, the first buffer device 111 may include a plurality of buffer members 1111. As shown in FIG. 6, each buffer member 1111 is provided with an arc surface, and when the mirror cover 12 slides relative to the mirror frame 11, at least a The curved surface of a buffer member 1111 collides with the side surface of the mirror cover 12 to increase the damping force and play a better buffering effect.

Further, shock-absorbing rubber can be attached to the curved surface, and the shape of the shock-absorbing rubber and the curved surface is adapted to better buffer and reduce noise, so that the mirror cover 12 slides more smoothly.

In one embodiment, as shown in FIG. 8 , the second buffer device 28 includes a plurality of buffer ribs 281 . When the mirror cover 12 slides to the end of the stroke, at least one buffer rib 281 collides with the mirror cover 12 , which can It is better to buffer the impact force when the mirror cover 12 is fully opened.

Further, the mirror cover 12 is provided with a baffle 123, one end of the baffle 123 is fixed with the mirror cover 12, and the other end extends in a direction perpendicular to the sliding direction of the mirror cover 12. When the mirror cover 12 slides to the end of the stroke At least one buffer rib 281 is in conflict with the baffle 123 . With this structure, when the baffle 123 collides with the buffer rib 281 , the baffle 123 itself can shake slightly, so as to better relieve part of the impact force.

Further, the lengths of the plurality of buffer rib plates 281 are different, and this structure can make the buffer force between the baffle plate 121 and the buffer rib plate 261 in contact with each other gradually weaken. Specifically, a certain part of the baffle plate 121 First, the longer buffer rib 261 is contacted to achieve primary buffering, and then another part of the baffle 121 is brought into contact with another relatively short buffer rib 261 to achieve secondary buffering, and so on to achieve gradual buffering. , to enhance the buffering effect.

Preferably, the lengths of the plurality of buffer ribs 281 increase sequentially in the direction perpendicular to the sliding direction of the mirror cover 12. It is understood that the increase may be from top to bottom, or from bottom to top Increment. This structure can better realize gradual buffering according to the force of the baffle 121 and enhance the buffering effect.

Further, the cross section of the buffer rib 281 is trapezoidal, which can better enhance the buffer effect.

In one embodiment, as shown in FIG. 2 , a warning label 10 is also attached to the sun visor body 2 , and the warning label 10 and the mirror cover 12 are located on the same side of the sun visor body 2 , and the sun visor with the warning label 10 is attached. The side of the board body 2 is always facing the driver's direction, and the rotating shaft 3 is arranged in the driver's direction. The sun visor body 2 is turned between the first position and the second position around the rotating shaft 3. When the sunshade is required, the sun visor body 2 is turned around the rotating shaft 3 from the front windshield to the driver's direction to the first position. When the sunshade is not required, the sun visor body 2 The body 2 is turned from the driver's direction to the front windshield direction around the rotating shaft 3 to the second position, so that the side of the sun visor body 2 attached with the warning label 10 always faces the driver's direction. Since regulations require that the airbag warning label on the sun visor on the co-driver's side is visible on both sides, the sun visor in the prior art usually adopts the method of affixing warning labels on both sides. The warning label is visible. When the sunshade is not needed, the sunshade is turned up. At this time, the warning label on the other side of the sunshade is visible. This method needs to be bonded twice, and each bonding operation needs to enable the relevant The tooling equipment is used to complete, the operation is cumbersome, the production cost is high, and the use effect is not good. In this embodiment, through the above design, the warning label 10 can be affixed only on one side of the sun visor body 2, and the warning label 10 is visible during the overturning process of the sun visor body 2 (forward rotation and reverse rotation process). Simple, with better user experience.

The warning label 10 here can be a safety warning label, or a sticky note used to warn and remind time, events, and the like.

Preferably, the warning label 10 may be an airbag warning label, which usually displays "Do not place a rear-facing child seat on a seat protected by an airbag, otherwise death or serious injury may be caused".

In order to better make the warning label 10 always appear in the driver's field of vision, the following embodiments can be used to control the turning angle of the sun visor body 2 .
