Therefore, it should not be understood as a limitation on the present invention.

[0022] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0023] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0024] In the prior art, the vanity mirror light 004 is turned on and off by rotating the vanity mirror cover 200. A conductive sheet is provided on the cover, and a conductive sheet is provided on the vanity mirror frame 100. Circuit conduction is achieved when the conductive sheet on the cover and the conductive sheet on the vanity mirror frame 100 are in rigid contact. Because the two are in rigid contact, they experience significant wear during relative motion, creating a gap that can lead to poor conduction, reduced control sensitivity, and shortened service life.

[0025] In view of this, the designer provides a silent control switch assembly for the makeup mirror, which is not easy to wear out and fail, has sensitive control and a long service life; and is not easy to produce abnormal noise and affect the riding environment.

[0026] Please refer to Figures 1-6 , this embodiment provides a silent control switch assembly for a makeup mirror, comprising: A makeup mirror frame 100, a makeup mirror cover 200, and a silent switch 300; the makeup mirror frame 100 is used to be mounted on the sun visor body 001, the makeup mirror cover 200 is rotatably connected to the makeup mirror frame 100, and the makeup mirror cover 200 has a first position and a second position that can be switched between each other; the silent switch 300 is provided with an elastic trigger member 310 and is mounted on the makeup mirror frame 100; When in the first position, the makeup mirror cover 200 is attached to the makeup mirror frame 100, and there is a distance between the makeup mirror cover 200 and the elastic trigger part 310, so that the silent switch 300 is in the off state; when in the second position, the makeup mirror cover 200 is unfolded relative to the makeup mirror frame 100, and the makeup mirror cover 200 presses the elastic trigger part 310, so that the silent switch 300 is in the on state.

[0027] As described above, the working principle of the silent control switch for the makeup mirror provided in this embodiment is as follows: The vanity mirror is mounted on the sun visor. Initially, the vanity mirror cover 200 is in the first position, obscuring the mirror body 003 on the vanity mirror frame 100, and the sun visor is positioned flush against the vehicle roof. In this position, the vanity mirror cover 200 does not press the elastic trigger 310, the silent switch 300 is off, and the vanity mirror light 004, electrically connected to the silent switch 300, is off. To use the vanity mirror light 004, the sun visor is first opened, and then the vanity mirror cover 200 is rotated from the first position to the second position. The rotation of the vanity mirror cover 200 allows it to contact the elastic trigger 310, pressing the elastic trigger 310 to turn the silent switch 300 on. This energizes the silent switch 300, turning on the vanity mirror light 004.

[0028] It should be understood that when the makeup mirror light 004 is turned on and off by rotating the makeup mirror cover 200, the makeup mirror cover 200 contacts the elastic trigger part 310, and the two are elastically matched. The makeup mirror cover 200 can drive the elastic trigger part 310 to move together, which has less wear than a rigid fit; and the elastic force of the elastic trigger part 310 itself can adaptively compensate for the gap caused by wear or assembly errors, thereby improving control sensitivity, extending service life, and reducing maintenance costs.

[0029] The following embodiments illustrate the details of the silent control switch assembly of the vanity mirror of the present application by way of examples.

[0030] Please refer to Figures 1-4 In this embodiment, optionally, the silent switch 300 includes a housing 320, a first conductive sheet 330, and a second conductive sheet 340. The housing 320 is connected to the makeup mirror frame 100, and the first conductive sheet 330 and the second conductive sheet 340 are both connected to the housing 320, and the two are arranged at intervals; the elastic trigger member 310 is elastically connected to the housing 320, and the elastic trigger member 310 is used to electrically connect to the first conductive sheet 330 and the second conductive sheet 340 at the same time when the makeup mirror cover 200 is in the second position.

[0031] It should be understood that the silent switch 300 has a simple structure, is easy to manufacture, and is also easy to assemble. Furthermore, by virtue of the elastic trigger member 310 being in electrical contact with both the first conductive sheet 330 and the second conductive sheet 340, the silent switch 300 is in an on state, activating the vanity mirror light 004. This provides a simple and reliable interface.

[0032] Furthermore, when the switch assembly is mounted on the sun visor, the first conductive sheet 330 and the second conductive sheet 340 are connected to the positive and negative poles of the power supply via power lines, respectively, and the vanity mirror light 004 can be installed on the connection line between the power supply and the first conductive sheet 330, or on the connection line between the power supply and the second conductive sheet 340. When the first conductive sheet 330 and the second conductive sheet are electrically connected via the elastic trigger member 310, the circuit is completed and the vanity mirror light 004 lights up.

[0033] Optionally, the elastic trigger member 310 includes a conductive head 311 and an elastic body 312. The conductive head 311 is slidably mounted on the housing 320. The elastic body 312 contacts both the housing 320 and the conductive head 311. The elastic body 312 is configured to cause the conductive head 311 to move away from the first conductive sheet 330 and the second conductive sheet 340. When the makeup mirror cover 200 is in the second position, the conductive head 311 is configured to be electrically connected to the first conductive sheet 330 and the second conductive sheet 340 simultaneously under the pressure of the makeup mirror cover 200. The conductive head 311 and the elastic body 312 are independently processed and then assembled together, reducing the difficulty and cost of manufacturing. Furthermore, they can be replaced independently, reducing maintenance costs.

[0034] It should be understood that the elastic body 312 can be set as a spring. The spring has a simple structure, is easy to process and manufacture, and has a long service life.

[0035] Please refer to Figures 1-4 Furthermore, the conductive head 311 includes a pressing rod 3111, a first leg 3112, and a second leg 3113. The housing 320 is provided with an assembly through-hole, into which the pressing rod 3111 is inserted. The first leg 3112 and the second leg 3113 are both connected to the pressing rod 3111. The elastic body 312 is in contact with both the pressing rod 3111 and the housing 320. One end of the first leg 3112 is electrically connected to one end of the second leg 3113. The other end of the first leg 3112 is electrically connected to the first conductive sheet 330, and the other end of the second leg 3113 is electrically connected to the second conductive sheet 340.

[0036] It should be understood that the pressing rod 3111 can be configured as a metal conductive member, and the first leg 3112 and the second leg 3113 can be electrically connected through the pressing rod 3111. During assembly, the first leg 3112 and the second leg 3113 can be welded to the pressing rod 3111.

[0037] In this embodiment, optionally, a side of the first conductive sheet 330 proximate to the second conductive sheet 340 is spaced apart from the housing 320; and a side of the second conductive sheet 340 proximate to the first conductive sheet 330 is spaced apart from the housing 320. This design allows portions of the first and second conductive sheets 330 and 340 to be suspended in the air. The portions of the first and second conductive sheets 330 and 340 suspended from the housing 320 can undergo a certain displacement, generating an elastic force to restore the deformation. During use, when the makeup mirror cover 200 applies force to the pressing rod 3111, causing it to drive the first and second legs 3112 and 3113 to contact the first and second conductive sheets 330 and 340, respectively, the first leg 3112 and the first conductive sheet 330 and the second leg 3113 and the second conductive sheet 340, respectively, elastically contact each other. This allows for good contact even under vibration, ensuring stable and reliable use.

[0038] In this embodiment, the conductive head 311 is optionally provided with a driving bevel 3114 that extends out of the housing 320. A pressing protrusion 210 is provided on the makeup mirror cover 200. The pressing protrusion 210 is configured to contact the driving bevel 3114 when the makeup mirror cover 200 moves from the first position to the second position, thereby pressing the conductive head 311. The driving bevel 3114 may be a conical surface for ease of installation. When the pressing protrusion 210 contacts the driving bevel 3114, the pressing rod 3111 can be retracted into the housing 320, thereby causing the first leg 3112 and the second leg 3113 to contact the first conductive sheet 330 and the second conductive sheet 340, respectively, reducing the probability of the pressing protrusion 210 and the pressing rod 3111 interfering and becoming stuck.

[0039] In this embodiment, the silent control switch assembly for the vanity mirror optionally further includes a mounting plate 400. The silent switch 300 is secured to the mounting plate 400, which is engaged with the vanity mirror frame 100. Specifically, the housing 320 of the silent switch 300 is mounted on the mounting plate 400. Since the silent switch 300 is relatively small, the mounting plate 400 can be used to increase its size, thereby facilitating securement of the silent switch 300 to the vanity mirror frame 100 via the mounting plate 400.

[0040] In other embodiments, please combine Figure 5 and Figure 6 The silent switch 300 can also adopt other types of structures. For example, the conductive head 311 includes a pressing rod 3111 and a conductive spring 3115. The pressing rod 3111 can be semicircular in structure, and the conductive spring 3115 is snapped onto the bottom of the pressing rod 3111. By applying force to the pressing rod 3111, the conductive spring 3115 can be driven downward, thereby activating the switch. In addition, the housing 320 is configured as a split structure, which includes an upper cover 321 and a box body 322 that are interlocked and define a receiving cavity. The conductive spring 3115 is located in the receiving cavity, and the first conductive sheet 330 and the second conductive sheet 340 extend from the opposite sides of the box body 322.

[0041] Obviously, the structure of the silent switch 300 can also be adaptively adjusted, which is not exhaustively listed in this embodiment.

[0042] The silent control switch assembly for the makeup mirror provided in this embodiment has a makeup mirror cover 200 in contact with an elastic trigger member 310, and the two are elastically matched. The makeup mirror cover 200 can drive the elastic trigger member 310 to move together, which reduces wear compared to a rigid match. The elastic force of the elastic trigger member 310 itself can adaptively compensate for gaps caused by wear or assembly errors, thereby improving control sensitivity, extending service life, and reducing maintenance costs.

[0043] Please refer to Figures 1-4This embodiment also provides a sun visor, comprising a sun visor body 001, a mounting shaft 002, a mirror body 003, and the aforementioned silent control switch assembly for the vanity mirror. The mounting shaft 002 is secured to the vehicle body. The sun visor body 001 is rotatably connected to the mounting shaft 002, and the vanity mirror frame 100 is connected to the sun visor body 001. The mirror body 003 is mounted on the vanity mirror frame 100, and the vanity mirror cover 200 can open and close the mirror body 003. To use the vanity mirror, first rotate the sun visor body 001 to the open position, then rotate the vanity mirror cover 200, providing convenient operation.

[0044] In this embodiment, the sun visor optionally further includes a vanity mirror light 004, which is mounted on the vanity mirror frame 100 and electrically connected to a silent switch 300. By rotating the vanity mirror cover 200, the vanity mirror light 004 can be turned on, thereby facilitating the use of the vanity mirror in a dimly lit environment.

[0045] The sun visor provided in this embodiment is less likely to produce abnormal noise when the makeup mirror cover 200 is opened, and can provide a better riding environment and improve the comfort of riding in the car.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
