Description

Technical Field

[0001] This application relates to the field of LED light strip equipment technology, and in particular to an installation structure and grating screen for LED light strips. Background Technology

[0002] LED grating screens have a wide range of applications. With their excellent transparency design, they are often cleverly installed on the exterior walls of buildings to become an eye-catching advertising medium. While presenting wonderful images, these displays can maintain visual transparency to the original structure of the building, making them a favorite of advertising companies and a preferred solution for enhancing brand image and conveying business information.

[0003] LED strips are a key component on LED grating screens. Existing LED strip mounting structures typically involve extending the end cap from the side wall and fixing the end cap to the profile with screws through holes in the side wall. This type of structure is difficult to machine, complex to install, and the parts are prone to breakage, resulting in a low yield rate and a large number of scraps, making it unsuitable for mass production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an installation structure and grating screen for LED light strips to solve the problems existing in related technologies. The technical solution is as follows: In a first aspect, embodiments of this application provide an installation structure for LED light strips, including a profile, a light strip assembly, and an end cap. The light strip assembly is disposed within the profile, and the end cap is fixedly connected to the end of the profile via a snap-fit ​​connection assembly. The snap-fit ​​connection assembly includes: an insertion portion disposed on the inner side of the end cap, the insertion portion being interference-fitted with the inner sidewall of the profile; and a positioning portion disposed on the inner side of the end cap, the positioning portion engaging with a groove in the profile.

[0005] The end cap is connected to the inner wall of the profile through an interference fit of the inner insertion part, and forms an anti-loosening snap-fit ​​with the groove of the profile through the inner positioning part, so that the end cap can be stably fixed to the profile without screws. The installation is simple, the production cost is reduced, and it is suitable for mass production.

[0006] In one embodiment, the insertion portion includes a plurality of first reinforcing ribs with beveled surfaces, the bevels extending converging from the inside of the end cap towards the outer edge of the end cap. The first reinforcing ribs are interference-fitted with the inner wall of the profile, and the bevels ensure that the first reinforcing ribs can be smoothly inserted into the designated position.

[0007] In one embodiment, a plurality of first protrusions are provided on the surface of the first reinforcing rib, and the first protrusions abut against the inner sidewall of the profile. The first protrusions can enhance the interference fit between the first reinforcing rib and the inner sidewall of the profile and prevent loosening.

[0008] In one embodiment, the interference fit between the insertion part and the inner wall of the profile is -0.05mm ± 0.01mm.

[0009] In one embodiment, the positioning part includes a second reinforcing rib, the lower end of which is provided with a barb with an inclined surface. When the end cap is inserted into the profile, the second reinforcing rib undergoes elastic deformation, causing the barb to engage with the groove of the profile. The engagement of the barb at the lower end of the second reinforcing rib with the groove of the profile prevents the end cap from coming out of the profile under external force, ensuring stable installation.

[0010] In one embodiment, a plurality of second protrusions are further provided at the lower end of the second reinforcing rib. The second protrusions are located on both sides of the barb and abut against the profile. The second protrusions can work together with the first reinforcing rib to clamp the profile, improving the installation stability of the end cap on the profile.

[0011] In one embodiment, the barb is a cylindrical structure. Using a cylindrical structure for the barb reduces installation difficulty.

[0012] In one embodiment, the light strip assembly includes: a light board PCB and a cover covering the surface of the light board PCB; the cover is detachably connected to the profile. The cover covers the surface of the light board PCB and protects the light board PCB.

[0013] In one embodiment, a first buckle is provided on the face mask, and a second buckle is provided on the profile, with the first buckle and the second buckle engaging. The face mask and the profile are engaged by the first and second buckles, eliminating the need for screws and facilitating installation.

[0014] Secondly, embodiments of this application provide a grating screen, including a mounting structure for LED light strips.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following: In this application, the end cap is tightly connected to the profile through an interference fit on the outer side and is engaged with the profile groove through a positioning part, which can prevent the end cap from coming off. There is no need to process screw holes, so the end cap can be stably installed and fixed to the profile without screws. The installation is simple and convenient, reducing production costs and making it suitable for mass production.

[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0020] Existing LED strip mounting structures typically involve extending the end cap from the side wall and fixing the end cap to the profile using screws drilled through holes in the side wall. This type of structure is difficult to machine, complex to install, and the parts are prone to breakage, resulting in a low yield rate and a large number of scraps, making it unsuitable for mass production.

[0021] To improve the production efficiency of LED light strips and make them suitable for mass production, the LED light strip mounting structure of this application does not require the use of screws and screw holes. The reinforcing ribs extending from the side of the end cap are directly inserted into the profile, so that they are interference-fitted with the inner side wall of the profile to achieve the assembly purpose. This not only simplifies the installation process but also increases the yield rate and greatly shortens the processing time, making it suitable for mass production.

[0022] In the following description, only certain exemplary embodiments are briefly described to make the objectives, features, and advantages of this invention more apparent. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1 like Figure 1 As shown, this embodiment provides an installation structure for LED light strips, including a profile 101, a light strip assembly 102, and an end cap 103. The light strip assembly 102 is disposed within the profile 101, and the end cap 103 is fixedly connected to the end of the profile 101 via a snap-fit ​​connection assembly. Figure 2 As shown, the snap-fit ​​connection assembly includes: an insertion part 104 disposed inside the end cap 103, the insertion part 104 being interference-fitted with the inner wall of the profile 101; and a positioning part 105 disposed inside the end cap 103, the positioning part 105 being snapped into the groove of the profile 101.

[0025] In this embodiment, as Figure 3 As shown, the profile 101 has a mounting cavity and a groove. The inner side of the end cap 103 is provided with a plug-in part 104 and a positioning part 105. The position of the plug-in part 104 corresponds to the position of the inner wall of the mounting cavity on the profile 101 (hereinafter referred to as the profile inner wall 201). The position of the positioning part 105 corresponds to the position of the groove on the profile 101 (hereinafter referred to as the profile groove 202). The structure of the profile 101 is a conventional technical means for those skilled in the art, and will not be described in detail here.

[0026] During assembly, after aligning the insertion part 104 of the end cap 103 with the mounting cavity of the profile 101, an axial thrust is applied to insert the insertion part 104 into the mounting cavity of the profile 101, so that the insertion part 104 is interference-fitted with the inner sidewall 201 of the profile. The end cap 103 is then continuously pushed forward until the positioning part 105 engages with the groove 202 of the profile. At this time, the lower end of the positioning part 105 is engaged in the groove 202 of the profile. The interference fit between the insertion part 104 and the inner sidewall 201 of the profile allows the end cap 103 to be tightly connected to the profile 101. The engagement between the positioning part 105 and the groove 202 of the profile prevents the end cap 103 from coming off the profile 101 when subjected to external force, thereby achieving the installation and positioning effect of the end cap 103 on the profile 101.

[0027] Compared with the prior art, the structure of this application does not require the machining of screw holes, so that the end cap 103 can be stably installed and fixed to the profile 101 without the use of screws, and it is not easy to fall off. The installation is simple and convenient, reducing production costs and making it suitable for mass production.

[0028] like Figure 4 and Figure 5 As shown, the insertion part 104 includes a plurality of first reinforcing ribs 301 with inclined surfaces on their outer surfaces, the inclined surfaces extending from the inner side of the end cover 103 toward the outer edge of the end cover 103.

[0029] There are two first reinforcing ribs 301, which are mirror-symmetrically arranged on both sides of the end cap 103. See details. Figure 4 and Figure 5 The two first reinforcing ribs 301 correspond to the positions of the inner sidewall 201 of the profile; the outer surface of the first reinforcing rib 301 has a bevel, and the bevel is set with an angle that gradually decreases from the inner side of the end cap 103 toward the outer edge of the end cap 103. Figure 5 (The dashed line in the middle is a horizontal line for illustration), so that when the first reinforcing rib 301 is inserted into the profile 101, the outer diameter of the first reinforcing rib 301 gradually increases from small to large. The inclined surface ensures that the first reinforcing rib 301 can be smoothly inserted into the designated position, thereby improving the reliability of the interference fit connection between the two.

[0030] A plurality of first protrusions 302 are provided on the surface of the first reinforcing rib 301, and the first protrusions 302 abut against the inner sidewall of the profile 101.

[0031] At least one first protrusion 302 is provided on the surface of the first reinforcing rib 301, and the first protrusion 302 is located between the first reinforcing rib 301 and the inner sidewall 201 of the profile. The first protrusion 302 can further reduce the gap between the first reinforcing rib 301 and the inner sidewall 201 of the profile, enhance the interference fit effect, and thus avoid loosening.

[0032] The interference fit between the plug part 104 and the inner wall of the profile 101 is -0.05mm ± 0.01mm.

[0033] The interference fit between the plug portion 104 and the inner sidewall 201 of the profile is set to -0.05mm, which is the preferred interference fit range in this embodiment. In other embodiments, the interference fit between the plug portion 104 and the inner sidewall 201 of the profile can also be set to other numerical ranges.

[0034] like Figure 6As shown, the positioning part 105 includes a second reinforcing rib 401, and the lower end of the second reinforcing rib 401 is provided with a barb 402 with a bevel. When the end cap 103 is inserted into the profile 101, the second reinforcing rib 401 undergoes elastic deformation, so that the barb 402 engages with the groove of the profile 101.

[0035] The second reinforcing rib 401 is located in the middle of the end cap 103. The lower end of the second reinforcing rib 401 has a beveled barb 402. The inclination direction of the beveled surface of the barb 402 is consistent with the direction in which the end cap 103 is inserted into the profile 101. (See details...) Figure 6 When the second reinforcing rib 401 is inserted into the profile 101, the barb 402 abuts against the upper surface of the profile 101, and the second reinforcing rib 401 undergoes elastic deformation. When the end cap 103 reaches the set position, the barb 402 falls into the profile groove 202 and engages with the profile groove 202. The second reinforcing rib 401 elastically resets, which can prevent the end cap 103 from coming out of the profile 101 when subjected to external force, thereby achieving the installation and positioning effect of the end cap 103 on the profile 101.

[0036] A plurality of second protrusions 403 are provided at the lower end of the second reinforcing rib 401. The second protrusions 403 are located on both sides of the barb 402 and abut against the profile 101.

[0037] Multiple second protrusions 403 are disposed on the lower end face of the second reinforcing rib 401 and located on both sides of the barb 402. The second protrusions 403 on both sides are located directly above the first reinforcing ribs 301 on both sides, so that the second protrusions 403 and the first reinforcing ribs 301 clamp the profile 101 from the upper and lower positions respectively, playing a coordinated interference fit role, and further improving the installation stability of the end cap 103 on the profile 101.

[0038] The barb 402 has a cylindrical structure.

[0039] The barb 402 adopts a cylindrical structure, which reduces the difficulty of installation and facilitates production and processing; in other embodiments, the barb 402 may also be other geometric shapes.

[0040] The light strip assembly 102 includes: a light board PCB 501 and a cover 502 covering the surface of the light board PCB 501; the cover 502 is detachably connected to the profile 101.

[0041] The face mask 502 covers the upper surface of the lamp board PCB 501 and is detachably connected to the profile 101. The lamp board PCB 501 and the face mask 502 are installed together in the cavity of the profile 101, forming an integrated LED light strip structure together with the end cap 103.

[0042] like Figure 7As shown, a first buckle 601 is provided on the face mask 502, and a second buckle 602 is provided on the profile 101. The first buckle 601 and the second buckle 602 are engaged and connected.

[0043] Multiple first buckles 601 are provided on both sides of the lower end of the face mask 502, and second buckles 602 are provided on both sides of the upper end of the profile 101, as detailed below. Figure 7 The first buckle 601 and the second buckle 602 are matched and engaged to prevent the mask 502 from coming off the profile 101 when subjected to external force. Similarly, no screws are needed for fixing, which reduces the difficulty of installation.
