Description

Technical Field

[0001] The invention relates to the technical field of automobile makeup mirrors, and in particular to an opening and closing device for an automobile sun visor makeup mirror. Background Art

[0002] The car sun visor is a board installed above the driver and co-pilot's heads to prevent sunlight glare. It can help reduce the interference of sunlight on the driver's vision and improve driving safety. It can be flipped down when in use and flipped up and down, left and right when not in use.

[0003] For the convenience of daily use, current car sun visors are also embedded with makeup mirrors, which are mainly composed of a mirror frame, a lens and a mirror cover. The mirror cover is connected to the mirror frame through an opening mechanism so as to have the function of opening and closing. The opening mechanism can also automatically position the mirror cover after opening and automatically reset it when closing.

[0004] Since most of the current opening mechanisms are arranged between the rotating side edge of the mirror cover and the flipping side edge of the sun visor, the existing opening mechanism occupies a large space inside the sun visor, resulting in the inability to increase the width of the lens. Once the width of the lens is increased, the corresponding area inside the sun visor cannot accommodate the opening mechanism, and thus cannot break through the width limitation of the lens, thereby affecting the use effect of the makeup mirror and needs further improvement. Summary of the invention

[0005] In view of the current status of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an opening and closing device for a car sun visor makeup mirror which can release a larger space between the rotating side edge of the mirror cover and the flipping side edge of the sun visor to effectively eliminate the width restriction of the lens, thereby increasing the width of the lens to improve the use effect of the makeup mirror.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: an opening and closing device for a car sun visor vanity mirror, comprising a frame for embedding a lens and a mirror cover arranged on the top of the frame and capable of swinging open and close, characterized in that:

[0007] Two traction units are also provided between the rotating side of the mirror cover and the mirror frame, and the mirror cover can have automatic positioning function and automatic rebound function respectively when opened and closed by means of the two traction units;

[0008] The traction unit comprises a reed which is transversely embedded in the frame and has elasticity, and a pin which is transversely arranged on the lens cover, wherein the cross-section of the reed is in a Z-shape, and the front end of the reed is arranged higher than the rear end;

[0009] The front end of the spring sheet is formed with a bent section upward, and the end of the bent section can be movably extended to the top of the frame and located below the pin shaft;

[0010] A U-shaped hook portion is formed forward or backward at the end of the bent section, and the opening of the U-shaped hook portion is arranged downward. The U-shaped hook portion extends into the interior of the mirror cover and can be rotatably engaged outside the pin shaft so that the mirror cover is connected to the front end of the spring leaf through the pin shaft and can float up and down with the help of the elasticity of the spring leaf.

[0011] Preferably, two ear blocks are formed downwardly on the front lower side of the mirror cover and are symmetrically arranged on the left and right. Correspondingly, two support blocks are formed outwardly on the front side of the mirror frame and are respectively located below the two ear blocks. The front corners of the ends of the two ear blocks respectively cooperate with the tops of the two support blocks, and the pins in the two traction units are respectively inserted transversely in the two ear blocks.

[0012] Preferably, the top front edges of the two support blocks are each provided with a side cavity extending to the inside of the frame, the spring leaves in the two traction units are respectively arranged transversely in the two side cavities, and the ends of the bent sections extend to the top of the support blocks through the top opening between the side cavity and the support blocks.

[0013] Preferably, a limiting bending section arranged obliquely and forwardly is formed at the rear end of the spring sheet, and the end of the limiting bending section is pressed tightly against the top inner wall of the side cavity by means of its own elasticity.

[0014] Preferably, a stopper located outside the end of the limiting bending section is formed downward on the top inner wall of the side cavity to prevent the end of the limiting bending section from leaving the side cavity.

[0015] Preferably, a groove is formed at the end of each of the two ear blocks, and the U-shaped hook portions on the spring leaves in the two traction units extend into the two grooves respectively.

[0016] Compared with the prior art, the advantages of the present invention are: the present invention transfers the reed in the traction unit to the interlayer between the mirror frame and the automobile sun visor, and only sets the bent section on the reed between the rotating side edge of the mirror cover and the flipping side edge of the sun visor, thereby releasing a larger space between the rotating side edge of the mirror cover and the flipping side edge of the sun visor. In addition, the present invention also uses the elasticity of the reed itself to achieve a floating effect of the mirror cover during the opening and closing process, and also releases the space originally reserved for the rotation of the mirror cover inside the sun visor, thereby effectively eliminating the width restriction of the lens, thereby increasing the width of the lens to improve the use effect of the makeup mirror.

[0021] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0022] like Figures 1 to 3 As shown, an opening and closing device for a car sun visor vanity mirror comprises a mirror frame 1 for embedding a lens 2 and a mirror cover 3 disposed on the top of the mirror frame 1 and capable of swinging open and close;

[0023] Two symmetrically distributed traction units 4 are further provided between the rotating side of the mirror cover 3 and the mirror frame 1. The mirror cover 3 can have automatic positioning function and automatic rebound function after opening and when closing respectively by means of the two traction units 4;

[0024] The traction unit 4 includes a reed 41 which is transversely embedded in the frame 1 and has elasticity, and a pin 42 which is transversely arranged on the lens cover 3. The cross-section of the reed 41 is Z-shaped, and the front end of the reed 41 is arranged higher than the rear end.

[0025] A bent section 411 is formed upward at the front end of the spring leaf 41, and the end of the bent section 411 can be movably extended to the top of the frame 1 and is located below the pin 42;

[0026] A U-shaped hook portion 412 is formed at the end of the bending section 411 facing forward or backward, and the opening of the U-shaped hook portion 412 is set downward. The U-shaped hook portion 412 extends into the interior of the mirror cover 3 and can be rotatably engaged with the outside of the pin shaft 42 so that the mirror cover 3 is connected to the front end of the spring leaf 41 through the pin shaft 42 and can float up and down with the help of the elasticity of the spring leaf 41.

[0027] Two ear blocks 31 symmetrically arranged on the left and right are formed downward on the lower front side of the mirror cover 3. Correspondingly, two support blocks 11 are formed outward on the front side of the mirror frame 1 and are respectively located below the two ear blocks 31. The front corners of the ends of the two ear blocks 31 respectively cooperate with the tops of the two support blocks 11, and the pins 42 in the two traction units 4 are respectively inserted horizontally in the two ear blocks 31.

[0028] The top front edges of the two support blocks 11 are each provided with a side cavity 12 extending to the inside of the frame 1. The spring leaves 41 in the two traction units 4 are respectively arranged transversely in the two side cavities 12, and the ends of the bent sections 411 extend above the support blocks 11 through the top opening between the side cavity 12 and the support blocks 11.

[0029] A limiting bending section 413 is formed at the rear end of the spring leaf 41 and is arranged to be inclined forward. The end of the limiting bending section 413 is pressed tightly against the top inner wall of the side cavity 12 by virtue of its own elasticity.

[0030] A stopper 13 is formed downward on the top inner wall of the side cavity 12 and is located outside the end of the limiting bending section 413 to prevent the end of the limiting bending section 413 from being separated from the side cavity 12 .

[0031] A groove 32 is formed at the end of each of the two ear blocks 31 , and the U-shaped hook portions 412 on the spring leaves 41 in the two traction units 4 extend into the two grooves 32 respectively.

[0032] Working principle:

[0033] The mirror frame 1 is embedded and installed in the sun visor of the car. When the makeup mirror is needed, the mirror cover 3 is manually moved to swing it open. In the above process, the front corners of the ends of the two ear blocks 31 on the mirror cover 3 rotate with the mirror cover 3 and respectively press the tops of the two brackets 11, and then use the elasticity of the spring leaf 41 to force the end of the spring leaf 41 where the bent section 411 is located to deform toward the direction of the mirror cover 3, and then use the pins 42 in the two traction units 4 to make the mirror cover 3 float outward during the opening process. When the front corner of the end of the ear block 31 leaves the top of the bracket 11 and the front outer wall of the ear block 31 is attached to the top of the bracket 11, the mirror cover 3 will automatically stop.

[0034] After using the makeup mirror, the mirror cover 3 is moved in the reverse direction by hand, and the springs 41 in the two pulling units 4 will always generate a pulling force on the pin 42 by virtue of their own rebound force; when the front corner of the end of the ear block 31 again reverses away from the top of the bracket block 11 and the lower outer wall of the ear block 31 is attached to the top of the bracket block 11, the spring 41 will use its own rebound force to pull the mirror cover 3 back to its original position through the two pins 42 and keep the mirror cover 3 in a compressed state, thus achieving automatic closing.

[0035] The present invention transfers the spring leaf 41 in the traction unit 4 to the interlayer between the mirror frame 1 and the automobile sun visor, and only sets the bent section 411 on the spring leaf 41 between the rotating side edge of the mirror cover 3 and the flipping side edge of the sun visor, thereby releasing a larger space between the rotating side edge of the mirror cover 3 and the flipping side edge of the sun visor. In addition, the present invention also uses the elasticity of the spring leaf 41 itself to achieve the floating effect of the mirror cover 3 during the opening and closing process, and also releases the space originally reserved for the rotation of the mirror cover 3 inside the sun visor, thereby effectively eliminating the width restriction of the lens 2, thereby increasing the width of the lens 2 to enhance the use effect of the makeup mirror.
