Description

Technical Field

[0001] The present application relates to the technical field of automotive sun visors, and more particularly to a rotating structure of a mirror cover of an automotive sun visor. Background Art

[0002] An automotive sun visor is a board installed on the upper side of a cab to block sunlight. When in use, it can be flipped down to a predetermined angle, and when not in use, it can be flipped up without blocking the view. Most current automotive sun visors are provided with a makeup mirror to facilitate passengers to apply makeup or tidy their hair. A mirror cover is movably installed on the automotive sun visor, and the makeup mirror is covered by the mirror cover under normal conditions. Most existing mirror covers are installed on the automotive sun visor in a flipping or side-sliding manner.

[0003] Our company currently has a rotating structure of a mirror cover of an automotive sun visor installed on the automotive sun visor in a flipping form, as shown in Figure 1 and Figure 2 which includes a mirror frame 90 and a mirror cover 91. Both ends of the mirror cover 91 have an extending portion 911, and one side of each extending portion 911 has a guiding inclined surface 9111. The mirror frame 90 has a receiving groove 901, and both ends of the receiving groove 901 have an insertion hole 9011. The maximum distance between the two extending portions 911 is greater than the width of the receiving groove 901. The mirror cover 91 is made of plastic material. Due to the provision of the guiding inclined surface 9111 and the short length of the extending portion 911, during the process of pressing the mirror cover 91 into the receiving groove 901 with force, the extending portion 911 is bent and deformed, and after passing through the groove wall of the receiving groove 901 and being aligned with the insertion hole 9011, the extending portion 911 resumes its state before deformation. Since the maximum distance between the two extending portions 911 is greater than the width of the receiving groove 901, the mirror cover 91 is rotationally installed on the mirror frame 90. However: during the process of pressing the mirror cover 91 into the receiving groove 901, the extending portion 911 may undergo plastic deformation and become bent as a whole, making the already short extending portion 911 even shorter, or there is a risk that after the mirror cover 91 moves laterally a predetermined distance towards one end, the extending portion 911 at the other end of the mirror cover 91 disengages from the insertion hole 9011; in addition, since the extending portion 911 is pressed into the receiving groove 901 by deformation, if the length of the extending portion 911 extending into the insertion hole 9011 is too long, it is not easy to press the mirror cover 91 into the receiving groove 901, and if the length of the extending portion 911 extending into the insertion hole 9011 is short, the connection between the mirror cover 91 and the mirror frame 90 is not firm, and it is only applicable to mirror covers with a small length dimension.

[0004] Therefore, there is a need to provide a rotational structure for a sun visor mirror cover of an automobile, in which the mirror cover will not laterally disengage from the mirror frame and is suitable for a mirror cover with a relatively large length dimension. Summary of the Invention

[0028] The rotational structure of a schematic automotive sun visor mirror cover

[0029] Reference Figures 3 to 7 , according to a rotational structure of an automotive sun visor mirror cover of a preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, it includes a mirror cover 10, a mirror frame 20, and two shafts 30.

[0030] Specifically, as Figure 5 shown, one side of the mirror cover 10 has two buckling parts 101; as Figure 6 and Figure 7 shown, one side of the mirror frame 20 has two limiting grooves 201, the two limiting grooves 201 are spaced a predetermined distance apart, and the groove walls of each of the limiting grooves 201 are spaced a predetermined distance from the corresponding end of the mirror frame 20; the two shafts 30 respectively pass through the two buckling parts 101, and the two shafts 30 are both fixedly installed on the mirror frame 20, the buckling parts 101 are rotatably and movably installed on the corresponding shafts 30, the two ends of the shafts 30 are located outside the two ends of the groove walls of the limiting grooves 201, and each of the buckling parts 101 is placed in the corresponding limiting groove 201.

[0031] It should be noted that the rotation and buckling part 101 is rotatably and movably mounted on the shaft body 30, and both ends of the shaft body 30 are located outside the groove walls at both ends of the limit groove 201, and each rotation and buckling part 101 is placed in the corresponding limit groove 201. When the rotation and buckling part 101 moves a predetermined distance along the axial direction of the shaft body 30, the end of the rotation and buckling part 101 abuts against the groove wall at the end of the limit groove 201, thereby restricting the rotation and buckling part 101 from further moving in the original direction and disengaging from the shaft body 30. Obviously, compared with the prior art in which the insertion part is directly inserted into the insertion hole, there is a risk that the insertion part disengages from the insertion hole. The embodiment of the present application has the advantage that the lens cap will not laterally disengage from the lens frame. In addition, since the number of the rotation and buckling parts 101 and the length of the shaft body 30 can be increased according to the length and weight of the lens cap 10, compared with the limited insertion length of the insertion part into the insertion hole in the prior art, the embodiment of the present application has the advantage of being applicable to lens caps with larger length dimensions.

[0032] Further, to enable the shaft body 30 to pass through the lens cap 10, as Figure 5 shown, each rotation and buckling part 101 has a first through hole 1011, as Figure 7 shown, both ends of each limit groove 201 have a plurality of mounting parts 2011, and on the side of the lens frame 20 having the limit groove 201, there is also a second through hole 202. The second through hole 202 extends from one end of the lens frame 20 to the other end, and the second through hole 202 communicates with each limit groove 201 and passes through each mounting part 2011. The two shaft bodies 30 respectively extend into the second through hole 202 from both ends, and sequentially pass through the second through hole 202 on the mounting part 2011 and the first through hole 1011 on the rotation and buckling part 101, and the shaft body 30 is fixedly mounted on the mounting part 2011.

[0033] It should be noted that in the embodiments of the present application, the shaft diameter of the shaft body 30 is greater than the aperture of the second through hole 202, so as to facilitate the interference or transition fit between the shaft body 30 and the mounting portion 2011, and the shaft diameter of the shaft body 30 is less than or equal to the aperture of the first through hole 1011, so as to facilitate the circumferential rotation and axial movement of the rotation portion 101 along the shaft body 30; in addition, both ends of each limiting groove 201 are provided with two spaced-apart mounting portions 2011. During installation, the assembler first places the rotation portion 101 into the corresponding limiting groove 201, and then inserts the shaft body 30 into the second through hole 202 from one end of the mirror frame 20, and then successively passes through the second through holes 202 on the two mounting portions 2011, and then passes through the first through hole 1011 on the rotation portion 101, and then passes through the second through holes 202 on the two mounting portions 2011 on the other side of the limiting groove 201. The length of the shaft body 30 is greater than or equal to the maximum distance between the two outermost mounting portions 2011 at both ends of the limiting groove 201.

[0034] After restricting the axial movement of the rotation portion 101 along the shaft body 30 through the limiting groove 201, in order to restrict the circumferential rotation of the rotation portion 101 along the shaft body 30, as Figure 5 shown, each rotation portion 101 has a first arc surface 1012 and a second arc surface 1013, the first arc surface 1012 and the second arc surface 1013 are arranged in an intersecting manner, and the included angle between the first arc surface 1012 and the second arc surface 1013 is an acute angle, as Figure 7 shown, on the side of the mirror frame 20 having the limiting groove 201, there are also two mounting grooves 203, as Figure 4 shown, a first elastic piece 2031 is provided in each mounting groove 203. When the mirror cover 10 rotates a predetermined angle, one end of the first elastic piece 2031 abuts against the first arc surface 1012 or the second arc surface 1013.

[0035] It should be noted that, in the embodiment of the present application, the first elastic piece 2031 is U-shaped. One end of the first elastic piece 2031 is fixedly installed in the installation groove 203, and the other end of the first elastic piece 2031 abuts against the buckling part 101. In the normal state, when the lens cover 10 is parallel to the lens surface and covers the lens surface, the first elastic piece 2031 abuts against the first arc surface 1012 of the buckling part 101. When the lens cover 10 forms an acute angle or a right angle of more than 60° with the lens surface, the buckling part 101 rotates by a corresponding angle relative to the shaft body 30, and the first elastic piece 2031 abuts against the second arc surface 1013 of the buckling part 101, and applies a downward pressure to the second arc surface 1013. Then, after the second arc surface 1013, which is spaced from the shaft body 30 by a predetermined distance, is stressed, it provides an upward flipping force to one end of the lens cover 10 away from the second arc surface 1013, so as to ensure that the lens cover 10 can be fixed at a predetermined angle.

[0036] Further, to prevent the lens cover 10 from flipping too much, as Figure 5 shown, the lens cover 10 further has an extension part 102, and the extension part 102 is located between the two buckling parts 101. As Figure 6 shown, the lens frame 20 further has a notch groove 204, and the notch groove 204 is located between the two installation grooves 203, and the notch groove 204 is directly opposite to the extension part 102. As Figure 3 shown, a second elastic piece 2041 is provided in the notch groove 204. When the lens cover 10 rotates by a predetermined angle, the extension part 102 abuts against or separates from the second elastic piece 2041.

[0037] It should be noted that, in the normal state, when the lens cover 10 is parallel to the lens surface and covers the lens surface, the extension part 102 is separated from the second elastic piece 2041. After the lens cover 10 flips by a predetermined angle, the extension part 102 abuts against the second elastic piece 2041. At this time, the user can obviously feel resistance when flipping the lens cover 10 upwards, and at this time, the lens cover 10 can no longer be flipped. By setting the component with a blocking function as the elastic second elastic piece 2041, a certain buffer angle is provided when flipping the lens cover 10, rather than a hard contact.

[0038] Further, as Figure 7As shown, the mirror frame 20 includes a front blocking portion 205 and a rear blocking portion 206. The front blocking portion 205 and the rear blocking portion 206 are spaced apart by a predetermined distance and are located on the same side of the mirror frame 20. The limiting groove 201 is located on the front blocking portion 205. The notch groove 204 is located on the side of the rear blocking portion 206 facing away from the front blocking portion 205. The second through hole 202 is located on the side of the front blocking portion 205 close to the rear blocking portion 206, and the second through hole 202 extends from one end of the front blocking portion 205 to the other end. The mounting portion 2011 is located between the front blocking portion 205 and the rear blocking portion 206, and the mounting portion 2011 is fixedly connected to the side of the front blocking portion 205 close to the rear blocking portion 206. The fixed connection method includes but is not limited to injection molding as a single body. The mirror frame 20 further includes a plurality of reinforcing ribs 207. The reinforcing ribs 207 and the mounting portions 2011 are in one-to-one correspondence. Both ends of each reinforcing rib 207 are fixedly connected to the rear blocking portion 206 and the corresponding mounting portion 2011 respectively. The fixed connection method includes but is not limited to injection molding as a single body.

[0039] It should be noted that by providing the reinforcing ribs 207, the structural strength at the mounting portion 2011 is enhanced, and the risk that the mounting portion 2011 is broken by the shaft body 30 when the user forcefully pries the mirror cover 10 is reduced.

[0040] In summary, the rotation structure of the automotive sun visor mirror cover based on the embodiments of the present application is clarified, which provides advantages such as that the mirror cover will not laterally come out of the mirror frame and is applicable to mirror covers with larger length dimensions for the rotation structure of the automotive sun visor mirror cover.

[0041] It is worth mentioning that in the embodiments of the present application, the rotation structure of the automotive sun visor mirror cover has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economy. At the same time, for manufacturers, the rotation structure of the automotive sun visor mirror cover provided by the present application is easy to produce and has low costs, which is more conducive to controlling production costs and further conducive to the promotion and use of products.

[0042] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments.
