in the extended state, the locking mechanism 5 unlocks the positioning portion 42, the ejection mechanism 6 jacks up the positioning portion 42 in the direction toward the rear shell 3, the positioning portion 42 drives the rotating portion 41 and the lens 1 to jack up, so that the lens 1 extends out of the window 31 of the rear shell 3, the lens 1 and the rotating portion 41 can rotate relative to the positioning portion 42, and the positioning portion 42 is limited in the rear shell 3;

in the retracted state, the lens 1 is rotated to a position corresponding to the window 31, the positioning portion 42 is locked by the lock mechanism 5, and the lens passes through the window 31 and is retracted into the rear housing 3.

Specifically, as shown in fig. 1, the sun visor housing includes a front shell 2 and a rear shell 3, the front shell 2 being a housing facing the occupant when the sun visor is folded on the ceiling; the rear case 3 refers to a case in which the sun visor is turned downward to open the rear exposure window 31. The front shell 2 and the rear shell 3 are buckled to form a complete sun shield shell, and the lens 1, the rotary positioning mechanism 4, the locking mechanism 5 and the ejection mechanism 6 are all arranged on the inner wall of the shell. The rear shell 3 is provided with a window 31, and the lens 1 exposes the reflecting surface from the window 31.

The window 31 of the conventional posterior shell 3 has a smaller area than the lens 1, and limits the lens 1 to the inner side of the posterior shell 3.

The area of the window 31 in the invention is larger than that of the lens 1, so that the lens 1 can extend out of the window 31 to the outside of the rear shell 3, and the lens 1 can conveniently rotate after extending out.

The lens 1 is arranged transversely in the existing rectangular shape and is embedded in the sun visor housing, and the window 31 is also rectangular and arranged transversely, except that the dimensions of the long side and the wide side are larger than those of the lens 1. When the lens 1 extends from the rear housing 3, it can be rotated to a longitudinal arrangement, which facilitates the hair style and full face of the secondary driver.

As shown in fig. 1, the rotational positioning mechanism 4 includes a rotating portion 41 and a positioning portion 42, the rotating portion 41 is fixedly connected to the back surface of the lens 1, at least a portion of the rotating portion 41 rotates relative to the positioning portion 42, axial displacement (i.e., the extension and retraction direction) of the rotating portion 41 and the positioning portion 42 is limited, the positioning portion 42 is limited by the window 31 and cannot extend out of the window 31, and the lens 1 is prevented from completely falling off from the sun visor housing after extending out of the window 31.

As shown in fig. 1, the front case 2 is provided on an inner wall thereof with an ejector installation groove 21 and a lock installation groove 22, the ejector mechanism 6 is installed in the ejector installation groove 21, and the lock mechanism 5 is installed in the lock installation groove 22.

As shown in fig. 3, in the retracted state, the locking mechanism 5 locks the positioning portion 42, the positioning portion 42 drives the rotating portion 41 to retract into the housing, and the rotating portion 41 drives the lens 1 to retract into the housing. At this time, the ejection mechanism 6 is compressed.

As shown in fig. 2, when the lock mechanism 5 unlocks the positioning portion 42, the ejection mechanism 6 is released, and the ejection mechanism 6 pushes up the positioning portion 42, the rotation portion 41, and the lens 1 upward in fig. 2, so that the lens 1 protrudes from the window 31.

The extended lens 1 and the rotating portion 41 can rotate to an arbitrary angle with respect to the positioning portion 42. As shown in fig. 4, when rotated to arrange the long sides of the lenses 1 in the longitudinal direction, the hairstyle and the whole face can be irradiated; when it is necessary to retract into the sun visor housing again, the lateral arrangement corresponding to the shape of the window 31 is turned, and then the positioning portion 42 is locked again by the lock mechanism 5, and the positioning portion 42, the rotating portion 41 and the lens 1 are retracted together downward in fig. 3, so that the lens 1 passes through the window 31 and is retracted to the inside of the rear shell 3.

Optionally, as shown in fig. 1, the window 31 is covered with a shielding plate 32, and the shielding plate 32 slides along the length direction of the rear housing 3, so that the window 31 can be closed and opened. Before the lens 1 is extended, the shielding plate 32 is slid to open the window 31 completely.

Further, as shown in fig. 1, the rotating portion 41 is a rotating shaft, one end of which is fixedly connected to the lens 1 and the other end of which is rotatably connected to the positioning portion 42. Displacement between the rotary shaft and the positioning portion 42 in the direction of the rotation axis is restricted so that the rotary portion 41 and the positioning portion 42 do not disengage.

When the lock mechanism 5 locks the positioning portion 42, the first spring 63 is compressed, and the top post 62 is at least partially retracted into the base 61; when the lock mechanism 5 unlocks the positioning portion 42, the first spring 63 releases the energy to eject the top post 62 upward, and the top post 62 ejects the positioning portion 42 upward.

Preferably, the height of the ejector mechanism 6 when compressed needs to be made very small due to the limited thickness of the cavity in the visor housing. The top post 62 may be a multi-stage telescoping structure, including multi-stage telescoping tubing. The height during ejection is larger, and the retracted height is smaller, so that the thickness of the whole sunshade plate can be reduced.

In the first embodiment, the positioning portion 42 is a bracket made of a magnetic material, and the locking mechanism 5 is an electromagnet;

when the electromagnet is electrified, the bracket is adsorbed;

when the electromagnet is powered off, the support is jacked up by the ejection mechanism 6, and the support is separated from the electromagnet.

as shown in fig. 3, when the electromagnet is energized, magnetism is generated, the holder made of a magnetic material is attracted, the positioning portion 42 is retracted downward, and the first spring 63 of the ejection mechanism 6 is compressed.

Alternatively, the positioning portion 42 may be a bracket made of iron, or made of other magnetic materials.

Preferably, the electromagnet is a thin disc, the rotating portion 41 is a thin rotating shaft, and the positioning portion 42 is a bracket made of thin steel plate. As shown in fig. 3, when the lens 1 is retracted into the rear housing 3, the thickness of the entire sunshade can be made very thin.

In the first embodiment, when the lens 1 is used to irradiate a hairstyle and a full face, the positioning part 42 is unlocked by the locking mechanism 5, the lens 1 is ejected out of the window 31 of the rear shell 3 by the ejection mechanism 6, and the lens 1 can rotate after being extended out, so that the lens 1 which is originally rectangular and transversely placed can rotate to be longitudinally arranged, and the hairstyle and the full face can be irradiated; when the lens 1 is not needed, the lens 1 is rotated again so that the lens 1 is aligned with the window 31 and can be retracted into the rear case 3, and the positioning portion 42 is locked again by the locking mechanism 5. In the embodiment, the size of the existing lens and the arrangement direction in the sun visor are not required to be changed, and the hair style and the whole face can be irradiated while the requirements of regulations are met.

Specifically, the self-locking buckle 52 is an existing self-locking structure, and is used for switching between locking and unlocking by repeatedly pressing, and is often used for pressing a switch.

One end of the lock slider 51 can be inserted into the self-lock catch 52, and the lock slider 51 repeatedly moves toward the self-lock catch 52, thereby locking and unlocking with the self-lock catch 52.

In this embodiment, as shown in fig. 6, there are two locking sliders 51 and two self-locking buckles 52, and the two locking sliders 51 are disposed inside the two self-locking buckles 52 and move toward the self-locking buckles 52 along the transverse direction.

As shown in fig. 7, when the positioning bracket (positioning portion 42) is pressed downward, the positioning bracket moves toward the locking slider 51, and the positioning bracket pushes the locking slider 51 toward the self-locking catch 52, so that the self-locking catch 52 is locked with the locking slider 51, and the locking slider 51 is locked with the positioning bracket, at which time the positioning bracket also compresses the ejection mechanism 6.

As shown in fig. 6, the positioning bracket is pressed downward again, the positioning bracket pushes the locking slider 51 toward the self-locking buckle 52 again, so that the self-locking buckle 52 is unlocked from the locking slider 51, the locking slider 51 moves toward a direction away from the self-locking buckle 52, the locking slider 51 is separated from the positioning bracket, and the ejection mechanism 6 ejects the positioning bracket.

Further, as shown in fig. 6-7, a locking slot 421 is formed on the positioning bracket, and a locking hook 511 is arranged on the locking slider 51;

in the retraction state, after the self-locking buckle 52 is locked with the locking slider 51, the locking hook 511 of the locking slider 51 is inserted into the locking groove 421 of the positioning bracket;

in the extended state, the latch hook 511 is disengaged from the latch slot 421 during the process that the latch slide 51 moves away from the self-locking catch 52.

As shown in fig. 7, the locating piece 423 also serves to compress the ejection mechanism 6 in the retracted state.

The procedure for using the visor vanity mirror assembly of example two is as follows:

when the lens 1 needs to be extended, the lens 1 is pressed downwards, the lens 1 pushes the positioning bracket to move downwards, the positioning bracket pushes the locking slider 51 to move towards the self-locking buckle 52 along the transverse direction, the self-locking buckle 52 is unlocked, the locking slider 51 is released from the locking groove 421 in the process of moving towards the direction far away from the self-locking buckle 52, the ejection mechanism 6 ejects the positioning bracket upwards to separate the positioning bracket from the locking slider 51, and the positioning bracket upwards drives the lens 1 to extend out of the window 31.

Then, the lens 1 is rotated by dialing the rotation part 41, so that the lens 1 is arranged in the longitudinal direction.

After the lens is used, the lens 1 is rotated to be transversely arranged, the lens 1 is pressed downwards again, the lens 1 pushes the positioning support to move downwards, the positioning support pushes the locking slide block 51 to move towards the self-locking buckle 52 along the transverse direction, the self-locking buckle 52 is locked, meanwhile, the locking slide block 51 is locked with the positioning support, and the positioning support drives the lens 1 to retract into the rear shell 3.

In the second embodiment, the lens 1 is extended and retracted by pressing the lens 1, the operation mode is simple, the implementation is easy, the mechanical structure is pure, the circuit control is not needed, and the cost is lower.

In the second embodiment, the directions of locking and unlocking between the self-locking buckle 52 and the locking slider 51 are arranged along the transverse direction, and the transverse movement of the locking slider 51 is carried by longitudinally pressing the lens 1. This arrangement is advantageous in reducing the thickness of the positioning portion 42 and the lock mechanism 5 in the retracted state, and thus reducing the thickness of the overall structure, and can satisfy the layout of a thin internal space of the sun visor.

Example three:

as shown in fig. 8 to 14, the difference from the second embodiment is:

The positioning bracket is provided with a translation sliding groove 425, and when the positioning bracket is in an extending state, the rotating part 41 can slide back and forth along the translation sliding groove 425.

In the retracted state, the rotating portion 41 is locked and cannot slide further along the translation chute 425.

Further, as shown in fig. 9, the device further includes a fastening slider 7 and a second spring, wherein the fastening slider 7 is telescopically connected with the rotating portion 41 through the second spring;

in the extended state, the fastening slider 7 extends from the positioning bracket;

When the positioning portion 42 moves downward, the two tightening sliders 7 come into contact with the inclined surfaces of the two locking sliders 51, and as the positioning portion 42 continues to move downward, the two tightening sliders 7 are pushed in a direction to approach each other.

As shown in fig. 14, when the locking slider 51 is locked with the positioning portion 42, the protrusion 71 of the fastening slider 7 is inserted into the catching groove 413 of the rotating portion 41, and the rotating portion 41 is locked so that the rotating portion 41 cannot slide along the translational sliding groove 425.

In a third embodiment, the sun visor vanity mirror assembly is used as follows:

when the lens 1 needs to be extended, the lens 1 is pressed downwards, the lens 1 pushes the positioning support to move downwards, the positioning support pushes the locking slider 51 to move towards the self-locking buckle 52, the self-locking buckle 52 is unlocked, the locking slider 51 moves towards the direction far away from the self-locking buckle 52, the locking hook 511 is disengaged from the locking groove 421, the ejection mechanism 6 jacks the positioning support upwards, the positioning support is separated from the locking slider 51, and the positioning support upwards drives the lens 1 to extend out of the window 31.

Then, the lens 1 is rotated by dialing the rotation part 41, so that the lens 1 is arranged in the longitudinal direction. Meanwhile, the lens 1 can be pushed to slide along the translation sliding groove 425, the left and right directions of the lens 1 can be adjusted, and a wider range can be irradiated.

After use, the lens 1 is rotated to the lateral disposition and slid along the translating chute 425 to the centered position, aligned with the window 31. Pressing lens 1 downwards again, lens 1 promotes the locating support and moves down, and the locating support promotes locking slider 51 and moves towards auto-lock buckle 52, and with locking between the auto-lock buckle 52, locking slider 51 and locating support locking simultaneously, the locating support drives lens 1 and withdraws to the backshell 3 in, fastening slider 7 locks rotating part 41.

In the third embodiment, the lens 1 can be rotated to the vertical position and the lens 1 can be slid right and left to adjust the irradiation position of the lens 1.

In the third embodiment, the directions of locking and unlocking between the self-locking buckle 52 and the locking slider 51 are arranged along the transverse direction, and the transverse movement of the locking slider 51 is carried out by longitudinally pressing the lens 1 and the rotary positioning mechanism 4. This arrangement is advantageous in reducing the thickness of the positioning portion 42 and the lock mechanism 5 in the retracted state, and thus reducing the thickness of the overall structure, and can satisfy the layout of a thin internal space of the sun visor. As shown in fig. 14, in the retracted state, the rotational positioning mechanism 4 and the fastening slider 7 are retracted into the space between the two lock sliders 51, and the entire thickness of this portion corresponds to the thickness of the lock slider 51, so that the entire thickness can be reduced to be very thin.
