Description

Technical Field

[0001] The utility model relates to the field of cosmetic tools, in particular to a cosmetic mirror. Background Art

[0002] Mirrors are often used by people to tidy up their appearance. A clear and bright mirror can make it easier for people to dress up. Currently, there are more and more types and styles of mirrors, including luminous makeup mirrors and even digital displays set in supplementary light mirrors to display information such as time and temperature.

[0003] The mirrored surface primarily reflects light thanks to its metal coating (reflective layer). A digital display screen is installed inside the vanity mirror. To allow the characters on the digital display screen to be displayed through the metal coating, a window corresponding to the shape of the characters on the display screen is required. For aesthetic reasons, the edge of the window generally needs to coincide with the edge of the characters, or be slightly smaller than the edge of the characters. However, existing display screens inside vanity mirrors are typically positioned and fixed solely by screws. This screw positioning can lead to significant positional deviations in the digital display screen during installation, requiring multiple adjustments before the characters on the screen properly align with the window, making installation of the vanity mirror time-consuming, labor-intensive, and inefficient.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this invention; the terms "including" and "having" and any variations thereof in the specification and claims of this invention and the accompanying drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0062] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0063] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0064] See attached Figures 1 to 11 The present invention provides a makeup mirror comprising a bottom shell 1, a mirror body 2, a PCBA board 3, a display device 4, and a light-emitting device 5. Positioning bosses are provided within the bottom shell 1 to precisely position the PCBA board 3, thereby enabling more accurate positioning of the display device 4 relative to the corresponding portion of the mirror body 2.

[0065] Specifically, an installation cavity 101 is provided in the bottom shell 1, an opening 102 is provided at the top of the installation cavity 101, and a plurality of first positioning bosses 103 are provided in the installation cavity 101. The mirror body 2 is installed at the opening 102, and the mirror body 2 covers the opening 102. The mirror body 2 includes a light-transmitting layer 201, a light-reflecting layer 202 and a semi-transparent film 203. The light-transmitting layer 201 can be a transparent material such as acrylic, glass, etc., and the light-reflecting layer 202 can be a metal coating, preferably aluminum-plated. A plurality of character display windows 2021 are provided on the light-reflecting layer 202. The character display window 2021 is a hollow structure formed by laser engraving, and a semi-transparent film 203 is also coated on the character display window 2021. The edge size of the reflective layer 202 is smaller than the edge size of the light-transmitting layer 201, and the edge of the light-transmitting layer 201 forms a frosted layer 204 arranged around the reflective layer 202. The difference between the semi-transparent film 203 and the reflective layer 202 is that the transmittance of the two is different, and the reflective layer 202 is non-transparent. It should be noted that the reflective layer is plated on the bottom surface of the translucent layer. The relationship between the translucent layer, the reflective layer, the semi-translucent film and the frosted layer is as shown in the attached figure. Figure 5 shown.

[0066] As attached Figure 6 As shown, the front side 301, rear side 302, left side 303, and right side 304 of the PCBA board 3 respectively abut against at least one first positioning boss 103 to accurately position the PCBA board 3. The PCBA board 3 is then fixedly mounted within the mounting cavity 101 via bolts. The display device 4 is soldered to the PCBA board 3 and is also electrically connected to the PCBA board 3.

[0067] As attached Figure 2 、 6As shown, the display device 4 includes character lights 401. These lights can selectively illuminate to display numbers or symbols, with the character lights 401 positioned corresponding to the character display windows 2021. Specifically, the character lights 401 are primarily arranged in a digital "8" pattern, with each character selectively illuminating the numbers 0 through 9 or partially illuminating English letters. Of course, the display device 4 also includes corresponding character lights 401 for displaying symbols. Specifically, the number of character lights 401 matches the number of character display windows 2021, with each corresponding to the other.

[0068] The light emitting device 5 is disposed in the mounting cavity 101 at a position corresponding to the frosted layer 204 , and the light emitting device 5 is electrically connected to the PCBA board 3 .

[0069] In this embodiment, when the character lights 401 and the light-emitting device 5 are not illuminated, the light within the mounting cavity 101 is darker than the outside world. The image visible to the naked eye is primarily formed by the outside light reflected by the semi-transparent film, making the mirror body 2 appear as a normal mirror. When the character lights 401 and / or the light-emitting device 5 are illuminated, the light within the mounting cavity 101 is brighter than the outside world. The portion of light emitted by the character lights 401 and / or the light-emitting device 5 that penetrates the semi-transparent film increases, making the image more distinct to the naked eye and making the light of the character lights 401 and / or the light-emitting device 5 visible to the naked eye. The display device 4 is a digital display screen, which is primarily used to display digital information, such as time information, temperature information, etc. The light-emitting device 5 is a flexible light strip, which is primarily used to provide lighting in dim conditions.

[0070] In addition, the size of the opening 102 is slightly larger than that of the mirror body 2, and a supporting boss 110 is provided around the opening 102 in the installation cavity 101, so that the mirror body 2 can move in a small plane. After the position of the mirror body 2 is adjusted, the mirror body 2 can be fixedly connected to the supporting boss by gluing.

[0071] Therefore, this embodiment limits and fixes the four directions of the PCBA board 3 by setting a plurality of positioning bosses, thereby improving the positioning accuracy of the PCBA board 3, which is equivalent to improving the positioning accuracy of the display device 4, so that the deviation between the character light 401 and the character display window 2021 becomes smaller. By slightly adjusting the position of the mirror body 2, the character light 401 and the character display window 2021 can be aligned with each other, and there is no need to repeatedly open the mirror body 2 and loosen the screws to adjust the position of the PCBA board 3.

[0072] Furthermore, the PCBA board 3 has a planar polygonal structure, such as a triangular structure, a quadrilateral structure, a pentagonal structure, a hexagonal structure, etc. The number of first positioning bosses 103 is at least equal to the number of sides 305 of the PCBA board 3, for example, the number of first positioning bosses 103 is twice or four times the number of sides 305 of the PCBA board 3. The greater the number of first positioning bosses 103, the more precise the positioning of the PCBA board 3 and the more stable the support. In this embodiment, the PCBA board 3 is rectangular, that is, the PCBA board 3 has four sides 305, which are divided into a front side, a rear side, a left side, and a right side. For example, there are eight first positioning bosses 103, so that each side 305 of the PCBA board 3 abuts against two of the first positioning bosses 103. For another example, there are 16 first positioning bosses 103, so that each side 305 of the PCBA board 3 abuts against four of the first positioning bosses 103. Furthermore, first positioning bosses 103 are positioned near corners 306 of the PCBA board 3. This corner fixation ensures precise positioning of the PCBA board 3, preventing rotation and slippage. Each corner 306 of the PCBA board 3 is assigned at least two first positioning bosses 103, which respectively abut against the two edges 305 forming that corner 306.

[0073] In this embodiment, as shown in the attached Figure 7 As shown, the first positioning boss 103 includes a receiving portion 1031 and a limiting portion 1032. The limiting portion 1032 is arranged perpendicular to the receiving portion 1031. The receiving portion 1031 is used to abut against the bottom surface 307 of the PCBA board 3, supporting the PCBA board 3 and raising the bottom surface 307 of the PCBA board 3 to improve the heat dissipation effect of the PCBA board 3. The limiting portion 1032 is used to abut against the edge 305 of the PCBA board 3 to position the PCBA board 3 and prevent the PCBA board 3 from moving in plane.

[0074] For further information, see the attached Figure 6 and 8 , a second positioning boss 104 and a third positioning boss 105 are further provided in the installation cavity 101, and the second positioning boss 104 and the third positioning boss 105 are interconnected and arranged perpendicular to each other. The makeup mirror also includes a battery 6, two adjacent side surfaces 601 of the battery 6 can be respectively pressed against the second positioning boss 104 and the third positioning boss 105 to position the battery 6, and then the battery 6 is fixed by gluing. In this embodiment, only one corner of the battery 6 needs to be positioned, which is convenient for manufacturers to install batteries 6 of different sizes according to different usage scenarios. Of course, a charging port 112 can also be provided on the bottom shell 1, and a charging connector 308 is integrated on the PCBA board 3, as shown in the attached Figure 9 and 11 shown.

[0075] For further information, see the attached Figure 2 and 8 A separator ring 106 is disposed within the mounting cavity 101, dividing the mounting cavity 101 into an inner cavity 1011 and an outer cavity 1012. The inner cavity 1011 is located inside the separator ring 106, while the outer cavity 1012 is located outside the separator ring 106. The first positioning boss 103, the second positioning boss 104, the third positioning boss 105, the PCBA board 3, and the display device 4 are all disposed within the inner cavity 1011, while the light-emitting device 5 is located within the outer cavity 1012. The separator ring 106 prevents the light from the light-emitting device 5 from affecting the display of the character light 401.

[0076] In this embodiment, the light-emitting device 5 is a flexible light strip, which is arranged around a separator ring 106 and is also glued to the separator ring 106. The light-emitting surface 501 of the flexible light strip faces away from the separator ring 106, and the separator ring 106 is arranged perpendicular to the mirror body 2. In other words, the light emitted by the flexible light strip does not directly hit the mirror body 2. Instead, it is reflected by the inner wall of the mounting cavity 101 and then penetrates the frosted layer 204. This makes the light emitted by the flexible light strip have a wider dispersion range and a softer light.

[0077] It can be understood that in order for the display device 4 to display time information and temperature information, the makeup mirror should also include a temperature sensor and a timer. The temperature sensor and the timer are electrically connected to the PCBA board 3. The temperature sensor and the timer are adapted to the display device 4. The display device 4 includes a time display area 402 and a temperature display area 403. The time display area 402 and the temperature display area 403 are both provided with character lights 401, and a character display window 2021 is opened on the mirror body 2 corresponding to the time display area 402 and the temperature display area 403.

[0078] For further information, see the attached Figure 3 、 9 To enable the temperature sensor to more accurately detect temperature, this embodiment further defines a through hole 107 on the bottom housing 1. Through hole 107 connects the mounting cavity 101 to the outside world, and the temperature sensor is disposed at through hole 107. Furthermore, a heat dissipation hole 111 is defined on the bottom housing 1. The makeup mirror further includes an indicator light 12, which is positioned corresponding to the heat dissipation hole 111 and is integrated with the PCBA board 3.

[0079] Furthermore, the makeup mirror further comprises a flip cover 7, which is hinged on the bottom shell 1 and can be swung to be parallel to the bottom shell 1 and rest against the top surface 108 of the bottom shell 1. When the makeup mirror is not needed, the flip cover 7 can be used to protect the mirror body 2.

[0080] In this embodiment, the makeup mirror further includes a first magnetic member 8 and a Hall switch 9. The first magnetic member 8 is mounted on the flip cover 7, and the Hall switch 9 is mounted within the mounting cavity 101 corresponding to the position of the first magnetic member 8. The Hall switch 9 is also integrated with the PCBA board 3. When the flip cover 7 is closed on the bottom shell 1, the first magnetic member 8 approaches the Hall switch 9, causing the Hall switch 9 to disconnect the electrical connection between the PCBA board 3 and the light-emitting device 5, thereby turning off the flexible light strip. When the flip cover 7 is opened, the first magnetic member 8 moves away from the Hall switch 9, causing the Hall switch 9 to connect the electrical connection between the PCBA board 3 and the light-emitting device 5, thereby turning on the flexible light strip. The first magnetic member 8 is a permanent magnet.

[0081] In order to prevent the flip cover 7 from opening automatically after being closed on the bottom shell 1, in this embodiment, refer to the attached Figure 3 and 6 , and the first magnetic component 8 is arranged close to the hinge 701 of the flip cover 7. The makeup mirror also includes a second magnetic component 10 and a third magnetic component 11. The second magnetic component 10 is installed on the flip cover 7 and is arranged away from its hinge 701. The third magnetic component 11 is installed in the installation cavity 101 corresponding to the position of the second magnetic component 10. When the flip cover 7 is closed on the bottom shell 1, the second magnetic component 10 and the third magnetic component 11 are magnetically connected to each other, providing a locking force for the connection between the flip cover 7 and the bottom shell 1. Among them, the second magnetic component 10 and the third magnetic component 11 are both permanent magnets, or one of them is a permanent magnet and the other is an iron alloy.

[0082] See attached Figure 10 The bottom surface 702 of the flip cover 7 defines a first mounting groove 703 and a second mounting groove 704. The first magnetic member 8 is disposed within the first mounting groove 703, and the second magnetic member 10 is disposed within the second mounting groove 704. The cosmetic mirror further includes a first mounting cover 13 and a second mounting cover 14. The first mounting cover 13 is glued to the first mounting groove 703, and the second mounting cover 14 is glued to the second mounting groove 704. Thus, the bottom surface 702 of the flip cover 7 and the first and second mounting covers 13, 14 together form a smooth surface.

[0083] For further information, see the attached Figure 2 and 6 At least three concentric support columns 109 are disposed within the mounting cavity 101, and preferably four concentric support columns 109. Each concentric support column 109 comprises at least two concentrically arranged cylinders 1091, the tops of which rest against the bottom surface 205 of the mirror body 2. When the mirror body 2 is pressed, the concentric support columns 109 increase their contact area with the mirror body 2, reducing the pressure exerted on the mirror body 2 and preventing the mirror body 2 from being broken due to excessive pressure.

[0084] In addition, for the brightness control of the light-emitting device 5, the information display control of the display device 4, etc., touch buttons with corresponding functions can be set on the PCBA board 3, and the PCBA board 3 can be controlled in real time by touching the corresponding position on the mirror body 2.

[0085] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned specific embodiments, or to make equivalent replacements for some of the technical features therein. Any equivalent structure made using the contents of the present invention specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of protection of the present invention patent.
