Description
Technical Field
[0001] This utility model relates to the field of automotive interior parts technology, and more specifically, to a flip-up magnetically controlled rear vanity mirror assembly. Background Technology
[0002] Rear vanity mirrors, as a key feature in automotive interiors that enhance passenger comfort and convenience, are widely used in the rear headliner area of various passenger vehicles. Their core function is to provide rear passengers with lighting and reflective aids for makeup and grooming through a flip-up mirror cover. Currently, most mainstream rear vanity mirrors on the market use a traditional mechanical touch-sensitive light control structure. Their working principle is as follows: a raised latch is located on the inside of the mirror cover, and contact copper plates, including a moving contact and a stationary contact, are mounted on the back of the light box. When the mirror cover is open, the latch mechanically presses against the moving contact, causing it to contact the stationary contact and conduct electricity, thus activating the lighting circuit. When the mirror cover is closed, the latch disengages from the moving contact, separating the moving and stationary contacts and disconnecting the circuit, thereby controlling the lighting.
[0003] However, the aforementioned traditional structure suffers from numerous insurmountable technical defects in practical applications, severely impacting the user experience and overall design of the automotive interior: Firstly, the lighting control logic relies on the mechanical contact between the latch and the contact copper plate. During the opening and closing of the mirror cover, the physical friction and collision between the latch and the contact plate easily produce abnormal switching noises such as "creaking." Especially in the quiet environment of a moving car, this noise significantly reduces ride comfort. Furthermore, after prolonged use, the contact plate is prone to wear and deformation, leading to poor contact and causing malfunctions such as flickering, constant illumination, or constant extinguishing of the light, resulting in insufficient reliability. Secondly, to accommodate the mechanical structure such as the latch, moving contact plate, and stationary contact plate, the light box needs to reserve sufficient installation and movement space, resulting in a larger overall thickness of the light box, which in turn increases the overall thickness of the rear vanity mirror assembly. The design trend of lightweight and thinner automotive interiors contradicts the current trend, limiting the flexibility of the roof area layout and potentially affecting the flatness and assembly compatibility of the roof interior. Thirdly, the exposed mounting structures of the mirror cover's clips and the light box's contacts require additional features such as grooves or protrusions on the mirror cover and light box surfaces, compromising the overall aesthetics and simplicity of the product. This results in poor appearance of the mating parts between the mirror cover and the light box, making it difficult to maintain consistency with the refined design style of the entire vehicle interior. Fourthly, the clearance between the mechanical contacts and clips needs strict control. Too large a clearance can lead to poor contact, while too small a clearance increases the resistance to opening and closing the mirror cover. Furthermore, under bumpy road conditions, even slight changes in the clearance can cause additional vibrations and noises, further degrading the user experience.
[0004] Therefore, there is an urgent need for a rear vanity mirror assembly that is noiseless, lightweight, stable, and provides excellent lighting. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] like Figures 1 to 7 As shown, this utility model provides a flip-top magnetically controlled rear vanity mirror assembly, including: a base 1 and a mirror box 4. One end of the base 1 and the mirror box 4 are hinged together, and the other end of the base 1 and the mirror box 4 are detachably connected by a fastener. The base 1 is fixedly connected to the car roof, and a magnetic control component for controlling the on / off of lighting is installed between the base 1 and the mirror box 4.
[0028] The base 1, serving as the overall load-bearing foundation, is injection molded from PP and glass fiber reinforced engineering plastics, forming a thin rectangular frame structure that ensures structural strength while maintaining lightweight design. Symmetrically mounted on both sides of the base 1 are retaining springs 14, which are U-shaped elastic structures made of spring steel. One end of the retaining spring 14 is fixed to a pre-set retaining spring 14 groove in the base 1 via an interference fit, while the other end protrudes outward. The elastic tension of the retaining spring 14 compensates for the dimensional tolerances of the car roof mounting holes, ensuring a tight fit between the base 1 and the roof, thus achieving initial fixation of the base 1 to the car roof.
[0029] The base 1 is also equipped with a connector 2 and a baffle 3. One end of the connector 2 is used to connect to the power line of the car body, and the other end is used to connect to the circuit components of the mirror box 4 to realize the transmission of power and signals. The baffle 3 completely covers the outside of the connector 2, forming a closed protective space, which can prevent dust, lint and other foreign objects from the inside of the headliner from entering the terminals of the connector 2, avoiding short circuits, and also has flame-retardant protection function.
[0030] The base 1 is rotatably connected to the mirror case 4 via a hinged connection between the pivot 7 and the pivot 7 seat, and is fixedly connected to the mirror case 4 after it is closed via a fastening mechanism. The base 1 and the mirror case 4 form a dual mechanical connection of hinge and fastening, balancing the flexibility of flipping and the stability of fixing. The fastening mechanism includes a fixing buckle 15 and a snap fastener 16. The fixing buckle 15 is installed on the edge of the base 1 and has a barb. The snap fastener 16 is installed on the edge of the mirror case 4. The barb and the snap fastener 16 are precisely matched and fastened, restricting the up, down, left and right movement of the mirror case 4 after it is fastened, and ensuring the stability of the closed case.
[0031] The mirror box 4 includes a mirror frame 5, a lens 6, an integrated circuit board, and an LED light group 17. The lens 6 is fixedly installed inside the mirror frame 5. The integrated circuit board is electrically connected to the Hall control element 13. The LED light group 17 is electrically connected to the integrated circuit board. The LED light group 17 is arranged on the back side of the lens 6 to achieve better makeup lighting effect. A pivot 7 is installed on one edge of the mirror frame 5. It also includes multiple cushioning pads 8, a frame 9, a fabric layer 10, and an EPP filling layer 11. The cushioning pads 8 are fixed to the outside of the mirror frame 5. The fabric layer 10 covers the outside of the frame 9. The EPP filling layer 11 is disposed between the frame 9 and the fabric.
[0032] The magnetic control assembly includes a magnet 12 and a Hall effect control element 13. The magnet 12, mounted on the base 1, serves as the signal source and is a neodymium iron boron permanent magnet, externally wrapped in an injection-molded plastic layer. It is fixed to the side of the base 1 near the rotating shaft 7 via an injection molding embedding process, with its surface flush with the base 1 to prevent collision damage during opening and closing of the lens case 4. The installation position of the magnet 12 is precisely aligned with the Hall effect control element 13 inside the lens case 4 to ensure accurate magnetic field sensing. The Hall effect control element 13 is an automotive-grade surface-mount Hall switch, soldered and fixed to an integrated circuit board. The integrated circuit board is arranged close to the back of the lens 6, which neither occupies extra space nor compromises the precise alignment of the Hall effect control element 13 with the magnet 12 on the base 1. This invention employs an injection-molded embedded magnet and a surface-mount Hall effect control element. The magnet is embedded into the base through an injection molding process, with its surface flush with the substrate, eliminating any protrusions that occupy space. The Hall effect control element is an automotive-grade surface-mount structure that can be directly soldered onto an integrated circuit board without the need for a separate mounting base. Compared to traditional contact components, which are three-dimensional mechanical structures, the overall thickness of the magnetic control component is reduced, thereby reducing space occupation and achieving a lightweight and thin design.
[0033] The frame 5 is rigidly connected to the skeleton 9. The lens 6 is embedded in the pre-set slot of the frame 5 and fixed with adhesive to ensure that the lens 6 is flat and does not wobble, resulting in a clear reflection. The skeleton 9 is the internal support structure of the mirror box 4 and is made of lightweight plastic. An EPP filling layer 11 is placed between the skeleton 9 and the fabric layer 10, balancing lightweight and cushioning performance. The fabric layer 10 is made of knitted fabric or suede fabric, the same as that used in car headliners, and is wrapped on the outside of the skeleton 9 through a heat-sealing process, so that the appearance of the mirror box 4 is consistent with the headliner fabric, improving the overall aesthetics and tactile comfort. The cushioning pad 8 is made of TPR soft elastic material and is fixed to the outside of the frame 5 with adhesive. When the mirror box 4 is closed, the cushioning pad 8 contacts the mating surface of the base 1, absorbing the closing impact and preventing abnormal noises from mechanical collisions, while also protecting the mating surfaces of the frame 5 and the base 1.
[0034] Working principle: Mirror box 4 closed state: When the mirror box 4 rotates and closes around the pivot 7, the buckle 16 on the edge of the mirror box 4 precisely engages with the fixing buckle 15 of the base 1 to achieve mechanical fixation. At this time, the magnet 12 on the base 1 moves to the position corresponding to the Hall control element 13 as the mirror box 4 closes. The stable magnetic field generated by the magnet 12 acts on the Hall control element 13, triggering the Hall effect, causing the output level of the Hall control element 13 to flip from high level to low level. After the integrated circuit board receives the low level signal, it controls the current circuit of the LED light group 17 to be disconnected, and the LED light is turned off. At the same time, the buffer pad 8 absorbs the closing impact force to avoid collision noise. Mirror box 4 open state: When the user manually flips the mirror box 4, the buckle 16 separates from the fixing buckle 15, the mirror box 4 flips around the pivot 7, the Hall control element 13 inside the mirror box 4 moves synchronously with the mirror box 4, the distance between it and the magnet 12 on the base 1 increases rapidly, the effect of the magnetic field on the Hall control element 13 disappears, the output level of the Hall control element 13 returns to a high level, after the integrated circuit board receives the signal, it closes the current loop of the LED light group 17, the constant current drive chip outputs a stable current, the LED light group 17 lights up, providing uniform lighting for the rear passengers. The whole process is free of friction and collision of mechanical contacts, realizing silent opening and closing.
