Description

Technical Field

[0001] This invention relates to the field of illuminated sign installation technology, specifically to a magnetic ultra-thin illuminated sign installation structure and its installation method. Background Technology

[0002] Existing illuminated sign installation structures suffer from drawbacks such as cumbersome installation processes, inconvenient maintenance, and excessive thickness, making them ill-suited to the dual demands of modern architecture for aesthetics and ease of use. Traditional illuminated sign structures rely heavily on screws or adhesives, resulting in inefficient installation and potential damage to walls or the sign itself during disassembly, leading to high maintenance costs. While magnetic structures significantly improve installation convenience, current designs still have several shortcomings: firstly, insufficient thinness, with most products exceeding 20mm in thickness, failing to meet the trend towards lightweight and flat designs; secondly, poor anti-detachment stability, with adsorption forces generally below 3kg, making them susceptible to detachment due to vibration or external forces; and thirdly, exposed conductive structures pose safety hazards. Summary of the Invention

[0003] In view of the above problems, the purpose of this invention is to provide a magnetic ultra-thin illuminated sign installation structure and its installation method. The magnetic design enables quick installation and disassembly, improving ease of operation; the ultra-thin feature optimizes space occupation and adapts to various installation scenarios; the innovative anti-detachment mechanism enhances reliability and avoids the risk of detachment caused by environmental factors (such as vibration and minor collisions); at the same time, the optimized insulation and conductive structure ensures safe use, reduces maintenance costs, and extends service life, thereby overcoming the shortcomings of the prior art.

[0004] This invention provides a magnetic ultra-thin illuminated sign mounting structure, comprising: a mounting rail, an insulating strip, a conductive strip, a magnetic strip, and an ultra-thin illuminated sign; the mounting rail is shaped like a concave aluminum profile, and its back is fixed to the interior or exterior trim or glass of an automobile; the insulating strip is symmetrically arranged on the inner wall of the groove of the mounting rail; the insulating strip is embedded in the inner wall of the groove and continuously arranged along the length of the mounting rail; a set of conductive strip grooves and a set of magnetic strip grooves are formed on the insulating strip, the conductive strip grooves and magnetic strip grooves are parallel to the mounting rail; the conductive strip is embedded in the conductive strip grooves, and the conductive strip has terminals at both ends for connecting to a power source; the magnetic strip is embedded in the magnetic strip grooves and is used for magnetic connection with a magnetic block on the back of the ultra-thin illuminated sign; a metal contact conductive sheet is provided on the back of the ultra-thin illuminated sign, and the metal contact conductive sheet is electrically connected to the conductive strip.

[0005] As a preferred embodiment of the present invention, the groove width of the mounting guide rail is 10mm and the height is 5mm.

[0006] As a preferred embodiment of the present invention, the insulating strip is made of highly elastic silicone material.

[0007] As a preferred embodiment of the present invention, the insulating strip has a cross-sectional width of 7 mm and a thickness of 2 mm.

[0008] As a preferred embodiment of the present invention, the width of the two conductive strip grooves in a set is 2mm and the depth is 1.5mm.

[0009] As a preferred embodiment of the present invention, the width of the two magnetic strip grooves in a set is 2mm and the depth is 1.5mm.

[0010] As a preferred embodiment of the present invention, a set of two conductive strip grooves are disposed at the middle position of the insulating strip along the width direction of the insulating strip, and a set of two magnetic strip grooves are symmetrically disposed on both sides of the insulating strip along the width direction of the insulating strip.

[0011] As a preferred embodiment of the present invention, the conductive strip is made of copper plated with tin.

[0012] As a preferred embodiment of the present invention, the magnetic strip is made of neodymium iron boron strong magnet.

[0013] Another objective of this invention is to provide an installation method for a magnetic ultra-thin illuminated sign installation structure, specifically including the following steps:

[0014] Step S1: Install and fix the guide rail. According to the vehicle installation position design, fix the concave aluminum profile to the preset installation surface with M3 bolts. Adjust the horizontal error of the installation guide rail to ≤0.5mm / m; ensure that the inner wall of the guide rail groove is clean and free of burrs.

[0015] Step S2: Embed the insulating strip. Press the high-elasticity silicone insulating strip into the groove along the length of the mounting rail, so that the insulating strip fits tightly against the inner wall of the groove of the mounting rail without loosening or lifting. The two ends of the insulating strip are flush with the end face of the rail. It can be cut if necessary.

[0016] Step S3: Installation of conductive strip and magnetic strip. Embed the copper-plated tin conductive strip into the conductive strip groove of the insulating strip, with the terminals exposed at both ends of the conductive strip for connecting to the power supply. Embed the neodymium iron boron magnetic strip into the magnetic strip groove of the insulating strip, making the surface of the magnetic strip flush with the surface of the insulating strip. After installation, seal the end of the guide rail with silicone plugs to prevent dust and moisture from entering.

[0017] Step S4: Illuminated sign adsorption. Insert the ultra-thin illuminated sign from one side of the mounting rail. Press the ultra-thin illuminated sign so that the magnetic block on the back automatically aligns with the magnetic strip on the mounting rail and is adsorbed and fixed. At the same time, the conductive sheet and the conductive strip make elastic contact. Check whether the sign is flat and without shaking.

[0018] Step S5: Power-on test. Connect the terminal block at the end of the mounting rail to a 12V DC power supply and check if the ultra-thin illuminated lettering lights up normally without flickering or abnormal heat generation. If there are any problems, adjust the lettering position or check the conductive contacts.

[0019] The advantages and positive effects of this invention are:

[0020] 1. This invention achieves quick installation and disassembly through magnetic design, improving ease of operation; optimizes space occupation with ultra-thin characteristics, adapting to various installation scenarios; enhances reliability through innovative anti-detachment mechanism, avoiding the risk of detachment caused by environmental factors (such as vibration, minor collision); at the same time, optimizes insulation and conductive structure, ensuring safe use, reducing maintenance costs and extending service life.

[0021] 2. This invention achieves an ultra-thin installation design for ultra-thin luminous signs. By using luminous signs with a thickness of ≤5mm and magnetic fixing, it meets the needs of modern minimalist aesthetics and reduces space occupation.

[0022] 3. This invention enables convenient installation. The magnetic structure allows for installation and disassembly in seconds, eliminating the need for screws, glue, or other auxiliary parts. This improves maintenance efficiency by more than 80% and reduces labor costs.

[0023] 4. This invention achieves anti-detachment stability. The neodymium iron boron strong magnetic material ensures that the adsorption force of a single piece is ≥5kg, and the overall adsorption force can withstand wind force ≥3 or slight collision, avoiding the risk of falling off, and is suitable for a variety of application scenarios.

[0024] 5. This invention has the advantages of safety and reliability. The silicone insulating strip isolates the conductive strip from the guide rail to prevent short circuits. Both the conductive strip and the magnetic strip are concealed to avoid the risk of electric shock and are suitable for complex environments such as humidity and dust.

[0034] In the following description, numerous specific details are set forth for illustrative purposes and to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

[0035] Example 1

[0036] See Figure 1-7 This embodiment of a magnetic ultra-thin illuminated sign installation structure includes: a mounting rail 1, an insulating strip 2, a conductive strip 3, a magnetic strip 4, and an ultra-thin illuminated sign; the mounting rail 1 is shaped like a concave aluminum profile, and the back of the mounting rail 1 is fixed to the interior or exterior trim or glass of an automobile; the insulating strip 2 is symmetrically arranged on the inner wall of the groove of the mounting rail 1; the insulating strip 2 is embedded in the inner wall of the groove and is continuously arranged along the length of the mounting rail 1; a set of conductive strip grooves and a set of magnetic strip grooves are provided on the insulating strip 2, and the set of conductive strip grooves and the set of magnetic strip grooves are parallel to the mounting rail 1; the conductive strip 3 is embedded in the conductive strip grooves, and the conductive strip 3 has terminals at both ends for connecting to a power source; the magnetic strip 4 is embedded in the magnetic strip grooves and is used to magnetically connect with the magnetic block 6 on the back of the ultra-thin illuminated sign; the back of the ultra-thin illuminated sign is provided with a metal contact conductive sheet, and the metal contact conductive sheet is electrically connected to the conductive strip.

[0037] In this embodiment, the insulating strip 2 is made of highly elastic silicone and is embedded in the inner wall of the concave profile, continuously arranged along the length of the guide rail. The insulating strip has a cross-sectional width of 7mm and a thickness of 2mm, and is machined with two conductive grooves (2mm wide and 1.5mm deep) and two magnetic grooves (2mm wide and 1.5mm deep). The grooves are parallel, with the conductive grooves located in the middle and the magnetic grooves symmetrically distributed on both sides. The insulating strip has insulation, buffering, and sealing functions.

[0038] In this embodiment, the conductive strip 3 is made of copper-plated tin material and is located in the conductive strip groove. Its size matches the groove (length as needed, width 2mm, thickness 1.5mm). It has terminals at both ends for connecting to the power supply.

[0039] In this embodiment, the magnetic strip 4 is made of neodymium iron boron strong magnetic material and is set in the magnetic strip groove. Its size matches the groove (length as needed, width 2mm, thickness 1.5mm) and corresponds to the magnetic block 6 at the back of the ultra-thin luminous sign.

[0040] In this embodiment, the ultra-thin illuminated letter label has an overall thickness of ≤5mm. A copper conductive contact sheet (with an arched, elastic design, measuring 10mm in length, 4mm in width, and 0.5mm in thickness) and a magnetic block 6 (10mm in length, 2mm in width, and 2mm in thickness) are fixed to the back. The conductive sheet and magnetic block 6 are evenly distributed along the back of the letter label to ensure reliable contact with the guide rail assembly.

[0041] The ultra-thin illuminated sign in this embodiment includes: an integrated ultra-thin sign composed of a PUR thin film shell layer 501, a PVD film layer 502, a light-shielding layer 503, and a PUR substrate 504 arranged sequentially from the outside to the inside; and a patch-type Mini LED flexible light strip module 505 disposed on the inner side of the PUR thin film shell layer 501. The PUR thin film shell layer 501 is a PUR thin film formed by reaction injection molding. The PVD film layer 502 is a light guide layer, and the inner surface of the PVD film layer 502 is screen-printed with microprism-shaped or scattering dots. The light-shielding layer 503 is an opaque layer co-injected or coated onto the PVD film layer. The patch-type Mini LED flexible light strip module 505 is embedded and encapsulated on the side of the PUR thin film shell layer 501 to form a side-entry light path. The thickness of the PUR thin film in the PUR thin film shell layer 501 is 0.5-1.5 mm. The ultra-thin illuminated sign is an ultra-thin illuminated car logo. The thickness of the PVD film layer 502 is less than 0.25 mm.

[0042] The processing technology of the surface-mount Mini LED flexible light strip module 505 in this embodiment is as follows:

[0043] Step S1: Fabrication of Mini LED flexible light strip. The blue light chip is transferred to a flexible substrate for die bonding. An optical sealing layer made of transparent epoxy resin is used to seal and fix the blue light chip on the flexible substrate. The flexible substrate is a flexible circuit board. The optical sealing layer is used to protect the blue light chip. A diffusing agent is added to the transparent epoxy resin material of the optical sealing layer. The diffusing agent is used to make the light emitted by the blue light chip more uniform.

[0044] Step S2: Fabrication of the PVD film. Dots are printed on the lower surface of a PVD film with a thickness of 0.25mm or more, or dots are formed by carbon dioxide laser. This allows the light from the Mini LED flexible light strip to enter from the side, be conducted within the PVD film, and have total internal reflection destroyed by the dots to form a uniform surface light source. A layer of adhesive film containing yellow phosphor is attached to the PVD film. The blue LED chip excites the yellow phosphor to form white light, thereby improving the light conversion efficiency and reducing energy loss.

[0045] Step S3: Install the Mini LED flexible light strip on the side of the PVD film and place a high reflectivity reflector sheet below the PVD film; thereby realizing the use of the Mini LED flexible light strip to emit light and enter the dotted PVD film from the side. The dot breaks the light and forms total internal reflection in the PVD film, so that the light enters the backlight cavity through the upper surface of the PC film to form a surface light source.

[0046] Working principle: The ultra-thin illuminated sign is inserted from the top of the mounting rail 1. The magnetic block 6 and the magnetic strip 4 are automatically aligned and magnetically fixed. The contact conductive sheet 5 of the ultra-thin illuminated sign makes elastic contact with the conductive strip 3 to achieve power conduction. When disassembling, the illuminated sign can be gently pulled along the opening direction of the mounting rail 1 to detach from the magnetic strip 4, achieving quick maintenance without the need for additional tools.

[0047] Example 2

[0048] This embodiment provides an installation method for a magnetic ultra-thin illuminated sign installation structure, which specifically includes the following steps:

[0049] Step S1: Install guide rail 1 and fix it. According to the vehicle installation position design, fix the concave aluminum profile to the preset installation surface with M3 bolts. Adjust the horizontal error of the installation guide rail to ≤0.5mm / m; ensure that the inner wall of the guide rail groove is clean and free of burrs.

[0050] Step S2: Embed the insulating strip 2. Press the high-elasticity silicone insulating strip 2 into the groove along the length of the mounting rail 1 so that the insulating strip 2 fits tightly against the inner wall of the groove of the mounting rail 1 without loosening or lifting. The two ends of the insulating strip are flush with the end face of the rail. It can be cut if necessary.

[0051] Step S3: Installation of conductive strip 3 and magnetic strip 4. Embed the copper-plated tin conductive strip 3 into the conductive strip groove of the insulating strip 2, with the terminals exposed at both ends of the conductive strip 3 for connecting to the power supply. Embed the neodymium iron boron magnetic strip 4 into the magnetic strip groove of the insulating strip 2, making the surface of the magnetic strip 4 flush with the surface of the insulating strip 2. After installation, seal the end of the guide rail with silicone plugs to prevent dust and moisture from entering.

[0052] Step S4: Illuminated sign adsorption. Insert the ultra-thin luminous sign from one side of the mounting rail 1. Press the ultra-thin luminous sign so that the magnetic block 6 on the back automatically aligns with the magnetic strip 4 on the mounting rail 1 and is adsorbed and fixed. At the same time, the conductive sheet and the conductive strip 4 make elastic contact. Check whether the sign is flat and without shaking.

[0053] Step S5: Power-on test. Connect the terminal block at the end of mounting rail 1 to a 12V DC power supply and check if the ultra-thin illuminated lettering illuminates normally without flickering or abnormal heat generation. If there is a problem, adjust the lettering position or check the conductive contacts.

[0054] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
