Description

Technical Field

[0001] This utility model relates to the field of COB LED strips, and in particular to a COB LED strip snap-on adhesive structure. Background Technology

[0002] COB LED strips are widely used in the lighting field due to their advantages such as uniform light emission, high brightness, and small size.

[0003] Currently, Chinese patent CN219655967U discloses a COB light strip that is easy to install. This utility model, by setting a transparent light-collecting cover, a propagation cavity, and an aerogel coating, can prevent the chip from being damaged due to folding without affecting the normal propagation of the chip light source, and can prevent the temperature generated during the use of the COB light strip from affecting the viscosity of the tape.

[0004] Currently, many COB LED strip installation methods use a single double-sided adhesive for direct pasting. This method is susceptible to temperature and humidity fluctuations, which can cause the adhesive to weaken and the COB LED strip to easily fall off. In addition, when the COB LED strip needs cleaning or maintenance, the adhesive method makes disassembly inconvenient and can easily damage the COB LED strip or the mounting surface, making subsequent reinstallation of the COB LED strip difficult. Utility Model Content

[0005] The main purpose of this utility model is to provide a snap-on adhesive structure for COB LED strips, which aims to solve the problems of existing COB LED strip installation methods that mostly use a single double-sided adhesive for direct installation. This method is easily affected by temperature and humidity, resulting in weak adhesion and easy detachment of the COB LED strip. In addition, when the COB LED strip needs to be cleaned or repaired, the adhesive installation method is inconvenient to disassemble, easily damaging the COB LED strip or the mounting surface, and making it difficult to reinstall the COB LED strip in the future.

[0006] To achieve the above objectives, the present invention proposes a COB LED strip snap-on adhesive structure, which includes a COB LED strip body, with connecting clips provided on the front and rear sides of the right side of the COB LED strip body, a snap-on mechanism provided on the left side of the connecting clips, and silicone double-sided adhesive glued to the right side of the connecting clips.

[0007] The snap-fit ​​mechanism includes a transparent plate, a card holder, a silicone block, and a snap-fit ​​block. The bottom of the transparent plate is fixedly connected to the surface of the card holder. The side of the silicone block near the transparent plate is fixedly connected to the transparent plate. The left side of the snap-fit ​​block is fixedly connected to the right side of the card holder. The surfaces of the transparent plate and the card holder are both in contact with the surface of the COB LED strip body. The bottom of the silicone block is in contact with the top of the COB LED strip body.

[0008] Preferably, the connector card has a card slot inside, and the card block is movably engaged inside the card slot.

[0009] Preferably, elastic sheets are fixedly connected to both the front and rear sides of the card holder, and limiting blocks are fixedly connected to the opposite sides of the two elastic sheets. Limiting holes are opened on both the front and rear sides of the connecting card, and the surface of the limiting block contacts the inner wall of the limiting hole.

[0010] Preferably, the elastic sheet is made of polyetheretherketone (PEEK), and a pull ring is fixedly connected to the top of the card holder.

[0011] Preferably, the bottom of the card block has a chamfer.

[0012] Preferably, anti-slip strips are fixedly connected to both the front and rear sides of the connector, and the number of anti-slip strips is several and evenly distributed on the front and rear sides of the connector.

[0013] Preferably, the transparent plate is made of thermoplastic polyurethane elastomer.

[0014] In this invention, when installing the COB light strip body, the COB light strip body is first clipped between the transparent plate and the bracket. The friction generated by the silicone block contacting the top of the COB light strip body provides a limiting and anti-slip effect, ensuring that the COB light strip body will not move laterally or detach from the bracket during use. Then, the protective film of the silicone double-sided adhesive on the right side of the connector is peeled off. The connector is then moved by holding the anti-slip strip and attached to the wall surface where it needs to be installed using the silicone double-sided adhesive. The good adhesion, high temperature resistance, and waterproof properties of the silicone double-sided adhesive ensure a stable connection between the COB light strip body and the wall surface. When the COB light strip body needs to be disassembled for cleaning or maintenance, the operator pulls the pull ring at the top of the bracket upwards. At this time, the limiting block is squeezed against the inner wall of the limiting hole, causing the elastic sheet made of polyetheretherketone (PEEK), which has good elasticity and fatigue resistance, to deform. This facilitates the limiting block's disengagement from the limiting hole, allowing the clip to move smoothly upwards and separate from the slot inside the connector. The COB light strip body can be installed without peeling off the silicone double-sided adhesive. The COB LED strip body is removed for cleaning or maintenance. After cleaning or maintenance, the locking block is aligned with the slot and inserted. During insertion, the chamfered design at the bottom of the locking block facilitates its smooth entry into the slot. Once the locking block is fully inserted, the elastic sheet returns to its original shape, moving the limiting block into the limiting hole. This re-engages the locking block with the slot and the limiting block with the limiting hole, completing the re-fixing and installation of the COB LED strip body. This solves the problems of existing COB LED strip installation methods that often use single double-sided adhesive for direct pasting, which is susceptible to temperature and humidity fluctuations, leading to weak adhesion and easy detachment of the COB LED strip. Furthermore, when the COB LED strip needs cleaning or maintenance, the adhesive installation method is inconvenient to disassemble, easily damaging the COB LED strip or the mounting surface, making subsequent reinstallation difficult. The transparent plate, made of thermoplastic polyurethane elastomer, ensures both the transparency and aesthetics of the structure while possessing good elasticity. It acts as a clamp for the COB LED strip body during the process of locking it between the transparent plate and the bracket. Attached Figure Description

[0027] This utility model provides a snap-on adhesive structure for COB LED strips, which aims to solve the problems of existing COB LED strip installation methods that mostly use a single double-sided adhesive for direct installation. This method is easily affected by temperature and humidity, resulting in weak adhesion and easy detachment of the COB LED strip. In addition, when the COB LED strip needs to be cleaned or repaired, the adhesive installation method is inconvenient to disassemble, easily damaging the COB LED strip or the mounting surface, and making subsequent reinstallation of the COB LED strip difficult.

[0028] like Figure 1-5 As shown, the present invention provides a COB LED strip snap-on adhesive structure, including a COB LED strip body 1, a connecting card 2 on the front and rear sides of the right side of the COB LED strip body 1, a snap-on mechanism 3 on the left side of the connecting card 2, and an organosilicon double-sided adhesive 7 pasted on the right side of the connecting card 2.

[0029] The snap-fit ​​mechanism 3 includes a transparent plate 301, a clip holder 302, a silicone block 303, and a snap-fit ​​block 304. The bottom of the transparent plate 301 is fixedly connected to the surface of the clip holder 302. The side of the silicone block 303 near the transparent plate 301 is fixedly connected to the transparent plate 301. The left side of the snap-fit ​​block 304 is fixedly connected to the right side of the clip holder 302. The surfaces of the transparent plate 301 and the clip holder 302 are in contact with the surface of the COB light strip body 1. The bottom of the silicone block 303 is in contact with the top of the COB light strip body 1.

[0030] In the technical solution of this utility model, when installing the COB light strip body 1, the COB light strip body 1 is first clipped between the transparent plate 301 and the card holder 302. The friction generated by the silicone block 303 contacting the top of the COB light strip body 1 provides a limiting and anti-slip effect, ensuring that the COB light strip body 1 will not move laterally during use and will not detach from the card holder 302. Then, the outer protective film of the silicone double-sided adhesive 7 on the right side of the connecting card 2 is peeled off. The connecting card 2 is moved by holding the anti-slip strip 5, and the connecting card 2 is pasted to the wall surface where it is to be installed using the silicone double-sided adhesive 7. The silicone double-sided adhesive 7, with its excellent adhesion, high-temperature resistance, and waterproof properties, ensures a stable connection between the COB light strip body 1 and the wall. When the COB light strip body 1 needs to be disassembled for cleaning or maintenance, the operator holds the pull ring 4 at the top of the clip 302 and pulls it upwards. At this time, the limiting block 8 is squeezed against the inner wall of the limiting hole 10, causing the elastic sheet 6, made of polyetheretherketone (PEEK) material with good elasticity and fatigue resistance, to deform. This facilitates the limiting block 8 to disengage from the limiting hole 10, and the clip 304 can smoothly move upwards and separate from the slot 9 inside the connecting clip 2 without tearing off the silicone double-sided adhesive 7. Remove the COB LED strip body 1 for cleaning or repair. After cleaning or repair, align the locking block 304 with the slot 9 and insert it. During insertion, the chamfer 11 at the bottom of the locking block 304 facilitates its smooth entry into the slot 9. Once the locking block 304 is fully inserted, the elastic sheet 6 returns to its original shape, moving the limiting block 8 into the limiting hole 10. This re-establishes the locking engagement between the locking block 304 and the slot 9, and between the limiting block 8 and the limiting hole 10, thus completing the re-fixing and installation of the COB LED strip body 1. This solves the problem of existing COB LED strip installation methods that often use a single double-sided adhesive strip. The traditional adhesive installation method is susceptible to temperature and humidity fluctuations, which can cause the COB LED strip to become loose and easily fall off. Furthermore, when the COB LED strip needs cleaning or maintenance, the adhesive installation method is inconvenient to disassemble, easily damaging the COB LED strip or the mounting surface, making subsequent reinstallation difficult. However, the transparent plate 301, made of thermoplastic polyurethane elastomer, ensures both the transparency and aesthetics of the structure while possessing good elasticity. It acts as a clamp to hold the COB LED strip body 1 during the process of attaching it between the transparent plate 301 and the bracket 302.

[0031] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The connecting card 2 has a slot 9 inside, and the card block 304 is movably engaged inside the slot 9. In this embodiment, the movable engagement structure between the slot 9 and the card block 304 makes the installation and disassembly process between the COB light strip body 1 and the connecting card 2 more convenient, and can be completed without the need for additional tools, thereby improving the installation efficiency of the COB light strip body 1 and the efficiency of subsequent cleaning and maintenance.

[0032] For further information, please continue to refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 The card holder 302 has elastic sheets 6 fixedly connected to both its front and rear sides. Limiting blocks 8 are fixedly connected to opposite sides of each elastic sheet 6. Limiting holes 10 are formed on both the front and rear sides of the connecting card 2, with the surface of the limiting block 8 contacting the inner wall of the limiting hole 10. In this embodiment, through the cooperative design of the elastic sheet 6, the limiting block 8, and the limiting hole 10, when the card block 304 is inserted into the card slot 9, the tight contact between the limiting block 8 and the limiting hole 10 effectively restricts the movement of the card block 304, preventing it from accidentally dislodging from the card slot 9.

[0033] Please continue to refer to this. Figure 2 The elastic sheet 6 is made of polyetheretherketone (PEEK), and a pull ring 4 is fixedly connected to the top of the card holder 302. In this embodiment, the use of PEEK material for the elastic sheet 6 combines high strength with good elasticity, making it less prone to fatigue fracture. This allows the elastic sheet 6 to deform when the limiting block 8 and the limiting hole 10 are compressed, facilitating contact and disengagement between the limiting block 8 and the inner wall of the limiting hole 10. This facilitates the installation and removal of the card block 304. The pull ring 4 allows for easy pulling of the card holder 302, facilitating disassembly.

[0034] Please refer to Figure 5 The bottom of the card block 304 is chamfered 11. In this embodiment, the chamfer 11 at the bottom of the card block 304 serves as a guide during installation, allowing the card block 304 to be inserted into the card slot 9 more smoothly.

[0035] Additionally, please refer to Figure 4 Anti-slip strips 5 are fixedly connected to both the front and rear sides of the connector 2. Several anti-slip strips 5 are evenly distributed on the front and rear sides of the connector 2. In this embodiment, the even distribution of the anti-slip strips 5 increases the friction on the surface of the connector 2. When the connector 2 is attached to the wall using silicone double-sided adhesive 7, the operator can hold the connector 2 more securely, preventing fingers from slipping.

[0036] Please refer to Figure 3 The transparent plate 301 is made of thermoplastic polyurethane elastomer. In this embodiment, the use of thermoplastic polyurethane elastomer for the transparent plate 301 provides good transparency and elasticity. The transparency allows the light emitted by the COB light strip body 1 to pass through the transparent plate 301 fully, reducing light loss, while the elasticity allows the transparent plate 301 to clamp the COB light strip body 1 during the snap-fit ​​process.

All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
