Description

Technical Field

[0001] This utility model belongs to the field of illuminated signs, and specifically designs a new type of aluminum alloy material illuminated sign connection structure. Background Technology

[0002] Currently, the connection between the light-emitting unit and the light-transmitting panel and the surrounding edge mainly relies on welding. However, welding has the following drawbacks:

[0003] 1. The welding process is complex, requires high skills from operators, and has low production efficiency;

[0004] 2. The high temperature generated during welding can easily cause thermal deformation of the aluminum alloy edging or translucent panel (such as thermoplastic materials), affecting the aesthetics and precision of the font.

[0005] 3. The welded joints pose a challenge in terms of waterproof sealing, especially in harsh outdoor environments where internal components are prone to moisture damage.

[0006] Although some solutions use adhesive bonding instead of welding, most of them are simple planar adhesive bonding or shallow groove adhesive bonding, which have problems such as limited adhesive contact area and insufficient adhesive force. Utility Model Content

[0007] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a new type of aluminum alloy material illuminated character connection structure.

[0008] The technical solution adopted in this utility model includes:

[0009] The edging has a first connecting groove and a second connecting groove forming a character-shaped structure on both sides.

[0010] The light-emitting unit includes a connecting plate connected in the first connecting groove and an LED connected to the connecting plate;

[0011] A light-transmitting plate is connected within the second connecting groove;

[0012] An adhesive component for bonding the connecting plate in the first connecting groove and the light-transmitting plate in the second connecting groove.

[0013] As a preferred embodiment of this utility model, both the first connecting groove and the second connecting groove are L-shaped connecting grooves;

[0014] Alternatively, the first connecting groove may be an L-shaped connecting groove, and the second connecting groove may be a U-shaped connecting groove;

[0015] Alternatively, both the first connecting groove and the second connecting groove may be U-shaped connecting grooves.

[0016] As a preferred embodiment of the present invention, the L-shaped connecting groove has a first side and a second side for connecting the connecting plate or the light-transmitting plate, the second side extending toward one side of the connecting plate or the light-transmitting plate.

[0017] As a preferred embodiment of the present invention, the first side and the second side are planar, and an adhesive space is formed between the first side, the second side and the connecting plate or the light-transmitting plate.

[0018] As a preferred embodiment of this utility model, the first side and the second side are recessed into a rectangular structure on the side away from the connecting plate or the light-transmitting plate to form an irregular surface, and the two irregular surfaces and the connecting plate or the light-transmitting plate form an adhesive space.

[0019] As a preferred embodiment of this utility model, the connecting plate is uniformly provided with a plurality of LED beads, and the plurality of LED beads are connected in parallel.

[0020] As a preferred embodiment of this invention, the light-transmitting plate is an acrylic plate or a PC plate.

[0021] As a preferred embodiment of this invention, the adhesive component is one of silicone sealant, polyurethane sealant, or silane polymer sealant.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model is a novel aluminum alloy material for connecting illuminated characters.

[0024] By forming L-shaped and U-shaped connecting grooves on both sides of the edging for bonding plates or light-transmitting panels, and by combining the L-shaped and U-shaped grooves according to the actual load-bearing weight, it is suitable for bonding light-transmitting panels or illuminated letter units of different weights. The L-shaped groove increases the bonding surface, while the U-shaped groove provides locking and fitting for bonding, effectively supporting heavy-duty components (such as multi-LED connecting plates or acrylic / quartz light-transmitting panels) and preventing gravity from causing them to fall. The adhesive components are used to connect the light-transmitting panels and connecting plates to the edging, replacing the traditional welding method. The adhesive components form a continuous and dense sealing layer while achieving the connection, achieving high sealing and waterproof performance and improving the waterproof performance of the internal LEDs. By designing irregular surfaces (such as recessed rectangles) on the sides of the L-shaped groove, the bonding space and the interlocking area between the adhesive and the edging are increased, significantly improving the anti-detachment performance.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] The following is combined with Figure 1-6 This invention describes a novel aluminum alloy illuminated letter connection structure, comprising:

[0039] The rim 1 has a first connecting groove 11 and a second connecting groove 12 forming a character-shaped structure on both sides.

[0040] The light-emitting unit includes a connecting plate 21 connected in the first connecting groove 11 and an LED bead 22 connected on the connecting plate 21;

[0041] The light-transmitting plate 3 is connected within the second connecting groove 12;

[0042] Adhesive component 4 is used for adhesively bonding the connecting plate 21 in the first connecting groove 11 and the light-transmitting plate 3 in the second connecting groove 12;

[0043] The light-emitting unit is fixedly connected in the first connecting groove 11 formed on one side of the perimeter 1, and the light-transmitting plate 3 is fixedly connected in the second connecting groove 12 formed on the other side of the perimeter 1. They are bonded to each other using adhesive parts 4. The irregular structure of the bonding space increases the bonding contact area between the light-transmitting plate 3 or the connecting plate 21 and the perimeter 1, thereby improving the stability of the bonding and the sealing and waterproof performance. At the same time, the bonding connection method can replace the traditional welding connection method, simplify the complex welding process, and improve production efficiency.

[0044] Please refer to Figures 2-6 As shown,

[0045] In the first embodiment of the first connecting groove 11 and the second connecting groove 12, both the first connecting groove 11 and the second connecting groove 12 are L-shaped connecting grooves. The connecting plate 21 or the light-transmitting plate 3 is connected in the L-shaped connecting groove and bonded by the adhesive 4. The L-shaped connecting groove can increase the contact area of ​​the connecting plate 21 or the light-transmitting plate 3 bonded in it, so as to improve the bonding stability.

[0046] In the second embodiment of the first connecting groove 11 and the second connecting groove 12, or where the first connecting groove 11 is an L-shaped connecting groove for connecting the light-transmitting plate 3, and the second connecting groove 12 is a U-shaped connecting groove for connecting the illuminated character unit 2, the light-transmitting plate 3 is made of PC material and is relatively lightweight. The L-shaped structure increases the bonding area, thereby improving bonding stability. When the mass and number of multiple LED beads 22 connected to the connecting plate 21 increase accordingly, increasing the bonding area to improve bonding stability requires additionally increasing the thickness of the connecting plate 21 to achieve the increased bonding area. The change is accompanied by a change in its own weight, so the connecting plate 21 bonded in the second connecting groove 12 is prone to falling off. In this embodiment, by forming the second connecting groove 12 into a U-shaped connecting groove structure, on the one hand, the U-shaped structure is used to snap and limit the connecting plate 21, and on the other hand, the adhesive 4 is used to bond the connecting plate 21 and the U-shaped structure to improve the sealing and stability of the connection. While replacing the traditional welding method, it can achieve a stable connection after the weight of the lamp bead 22 changes, so as to avoid the connection plate 21 and the lamp bead 22 on the connection plate 21 falling off during subsequent use. It should be noted that when the connecting plate 21 is in

[0047] In the third embodiment of the first connecting groove 11 and the second connecting groove 12, both the first connecting groove 11 and the second connecting groove 12 are U-shaped connecting grooves. When the weight of the lamp bead 22 is relatively heavy and the material of the light-transmitting plate 3 is replaced with a material with a weight higher than that of PC material (such as acrylic plate or quartz glass), the L-shaped connection cannot achieve a firm connection and there is a risk of falling due to gravity. In this embodiment, the first connecting groove 11 and the second connecting groove 12 are both formed into U-shaped structures to perform a snap-fit ​​and limiting connection between the connecting plate 21 and the light-transmitting plate 3, and adhesive is used to bond them simultaneously to avoid falling off after connection. It should be noted that in the installation connection of the connecting plate 21 on the edge 1 in this embodiment, the end plate 13 on the edge 1 is not an integrally formed structure with the main body. The connecting plate 21 needs to be inserted into the second connecting groove 12 at the opening of the end plate 13, and then the end plate 13 is connected to the edge 1 body by welding, bolting, bonding or other methods.

[0048] Please refer to Figure 6 As shown, the L-shaped connecting groove has a first side 111 and a second side 112 for connecting the connecting plate 21 or the light-transmitting plate 3. The second side 112 extends towards the connecting plate 21 or the light-transmitting plate 3 and is designed to improve the adhesive contact area. Both the first side 111 and the second side 112 are connecting surfaces for directly bonding the connecting plate 21 or the light-transmitting plate 3. It should be noted that in the installation connection of the connecting plate 21 and the light-transmitting plate 3 on the perimeter 1 in this embodiment, the end plate 13 on the perimeter 1 is not an integrally formed structure with the main body. It is necessary to insert the connecting plate 21 into the second connecting groove 12 at the opening of the end plate 13, or insert the light-transmitting plate 3 into the first connecting groove 11 at the opening of the end plate 13, and then connect the end plate 13 to the perimeter 1 body by welding, bolting, or bonding.

[0049] In the first bonding method between the first side 111 and the second side 112 and the connecting plate 21 or the light-transmitting plate 3, please refer to... Figure 4 As shown, the first side 111 and the second side 112 are planar, and an adhesive space 113 is formed between the first side 111, the second side 112 and the connecting plate 21 or the light-transmitting plate 3. The adhesive space 113 is used for bonding the connecting plate 21 or the light-transmitting plate 3 in the L-shaped connecting groove.

[0050] In the second bonding method between the first side 111 and the second side 112 and the connecting plate 21 or the light-transmitting plate 3, as shown in the figure, the first side 111 and the second side 112 are recessed into a rectangular structure 114 on the side away from the connecting plate 21 or the light-transmitting plate 3 to form an irregular surface. The two irregular surfaces and the connecting plate 21 or the light-transmitting plate 3 enclose an adhesive space 113. The surrounding edge 1 is a metal profile. The connecting plate 21 or the light-transmitting plate 3 is preferably a PC board, an acrylic board, or quartz glass. In this process, the anti-detachment performance of PC board, acrylic board, or quartz glass bonded to adhesive is better than that of metal profile bonded to adhesive. By recessing rectangular structure 114 on the first side 111 and the second side 112 to form a curved surface, the bonding space is increased, which can improve the bonding stability of connecting plate 21 or light-transmitting plate 3. At the same time, it can improve the bonding stability of adhesive part 4 to the first side 111 or the second side 112, and improve the anti-detachment performance of adhesive in the first connecting groove 11 or the second connecting groove 12.

[0051] Please refer to Figure 2 As shown, a plurality of LED beads 22 are evenly arranged on the connecting plate 21. The plurality of LED beads 22 are connected in parallel. The plurality of LED beads 22 provide a light source and transmit light through the light-transmitting plate 3.

[0052] Please refer to Figure 1 As shown, the light-transmitting plate 3 is an acrylic plate or a PC plate, and different materials can be used for fixed connection according to actual usage requirements.

[0053] Please refer to Figure 1 As shown, the adhesive 4 is one of silicone sealant, polyurethane sealant, or silane polymer sealant, to achieve a highly stable and well-sealed connection between the connecting plate 21 or the light-transmitting plate 3 and the surrounding edge 1.

[0054] Working principle of this utility model:

[0055] Several LED beads 22 are connected in series and connected to the connecting plate 21. The light-transmitting plate 3 and the connecting plate 21 are respectively connected to the first connecting groove 11 and the second connecting groove 12 formed on both sides of the rim 1 by adhesive 4, so as to realize the connection between the luminous character unit 2 and the light-transmitting plate 3 on the rim 1, replacing the transmission welding method.

[0056] In the first embodiment of the first connecting groove 11 and the second connecting groove 12, both the first connecting groove 11 and the second connecting groove 12 are L-shaped. In the connection between the light-transmitting plate 3 or the connecting plate 21 and the surrounding edge 1, the light-transmitting plate 3 is directly placed into the first connecting groove 11 and bonded by the adhesive 4, and the connecting plate 21 is directly placed into the second connecting groove 12 and bonded by the adhesive 4.

[0057] In the second embodiment of the first connecting groove 11 and the second connecting groove 12, the first connecting groove 11 is L-shaped and the second connecting groove 12 is U-shaped. The light-transmitting plate 3 can be directly placed into the first connecting groove 11 and bonded by the adhesive 4. In the connection between the connecting plate 21 and the surrounding edge 1, one end of the surrounding edge 1 is open. The connecting plate 21 is inserted into the surrounding edge 1 along the open end and connected by the adhesive 4. Then the end plate 13 is connected to the body of the surrounding edge 1 by welding, bolting or bonding.

[0058] In the third embodiment of the first connecting groove 11 and the second connecting groove 12, both are U-shaped. In the connection between the connecting plate 21 and the light-transmitting plate 3 and the surrounding edge 1, one end of the surrounding edge 1 is open. The connecting plate 21 and the light-transmitting plate 3 are inserted into the surrounding edge 1 along the open end and connected by the adhesive 4. Then the end plate 13 is connected to the body of the surrounding edge 1 by welding, bolting or bonding.

[0059] In the L-shaped connecting groove structure, a first side surface 111 and a second side surface 112 are formed in the groove to improve the bonding contact surface with the connecting plate 21 or the light-transmitting plate 3, thereby improving the bonding stability. At the same time, a rectangular structure 114 can be recessed in the first side surface 111 and the second side surface 112 to form an irregular surface, which on the one hand increases the size of the adhesive space 113, and on the other hand improves the prevention of the structural adhesive from falling off the edge 1 after curing.
