[0019] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0020] In the following description, specific examples are given to provide a more in-depth understanding of the invention. It is obvious that the described embodiments are merely some, not all, of the embodiments of the invention. It should be understood that the specific embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0022] To address the aforementioned technical problems, this application provides a frame structure that supports snap-fit ​​connections. Please refer to the appendix. Figure 1 To be continued Figure 7 The device includes a frame 1 and a back shell 2. A predetermined number of frame 1s are connected front to back to form a frame structure. The connection of the frame 1s can produce a triangular, square, or polygonal frame structure. Each frame 1 is provided with a first locking plate 11 and a second locking plate 12 facing the center of the frame structure. The first locking plate 11 and the second locking plate 12 of the same frame 1 are spaced apart to form a locking groove. The four periphery of the back shell 2 is provided with a locking flange 21. The locking flange 21 is locked and restricted in the locking groove so that the back shell 2 and the frame 1 enclose and form an accommodating cavity. The following describes the solution of this application in the context of a specific application scenario: In a panel light, the frame structure is used to house and protect the light-emitting module. During use, the user can directly insert the snap-fit ​​flange 21 into the slot. Since the back shell 2 and the frame 1 are generally made of modified metal or plastic, both of which have a certain degree of elasticity, the snap-fit ​​flange 21 is secured between the first locking plate 11 and the second locking plate 12 by means of the elasticity and appropriate size design. The first locking plate 11 and the second locking plate 12 effectively prevent the snap-fit ​​flange 21 from coming off. It can be seen that the slot and the snap-fit ​​flange 21 cooperate to achieve a stable snap-fit ​​between the frame 1 and the back shell 2, which will not easily separate. This eliminates the need for the traditional screw structure fixing method, simplifies the installation structure, and enables quick installation.

[0023] In this embodiment, the snap-fit ​​flange 21 is arranged around the frame to completely fill the gap between the frame structure and the back shell 2. It is easy to understand that under this design, the snap-fit ​​flange 21 forms a ring structure that is adapted to the frame structure. The inner ring is fixedly connected to the back shell 2, and the outer ring is snap-fitted with the frame structure, so that the axial direction of the back shell 2 is snap-fitted with the frame material 1, which greatly improves the overall stability of the frame structure.

[0024] In applications, it has been found that when the panel light is large (e.g., 60*20cm), the fit between the back shell and the frame is not tight enough, posing a risk of detachment. Therefore, in this embodiment, each of the second latching plates 12 has a first protruding strip 13 on the side near the first latching plate 11. The latching flange 21 extends from the center of the back shell 2 toward the frame 1 and is composed of a wave portion 14, a pressing plane portion 212, a limiting portion 213, and a first inclined portion 214 connected in sequence. The wave portion 14, the pressing plane portion 212, and the limiting portion 213 respectively fit the first side surface, the top surface, and the second surface formed by the first protruding strip 13. It is easy to understand that, from a cross-sectional perspective, The first protruding part 13, from the back shell 2 towards the frame 1, consists of the first side, the top surface, and the second side. The wave part 14 provides elasticity and pressure to compress the first side. The pressing flat part 212 generates a vertical force to compress the top surface. The limiting part 213 is used to abut against the third side. It can be understood that the limiting part 213, the wave part 14, and the pressing flat part together support the three sides of the first protruding part 13. On this basis, one side of the first inclined part 214 is pressed into the slot, and the other side strengthens the compressive force of the limiting part 213. With the above structure, the back shell 2 and the frame structure can be stably fixed together even in large-size designs.

[0025] In a further embodiment, a recessed groove 131 is provided on the top surface of the first protruding strip 13. This design greatly reduces the area of ​​the top surface and forms two peaks. Based on the characteristics of the structure, the peaks can generate elastic deformation better. At this time, the assembly between the back shell 2 and the frame structure is more stable.

[0026] In a further embodiment, the bottom of the slot includes a connected flat portion 14 and a second inclined portion 15. The flat portion 14 is perpendicular to the first locking plate 11, and the second inclined portion 15 is inclined to the second locking plate 12. The side of the first inclined portion 214 away from the limiting portion 213 is also provided with an abutting flat portion 215, which abuts against the angle iron-like mechanism formed by the first locking plate 11 and the flat portion 14. Under this design, the second inclined portion 15 can guide the first inclined portion 214 to slide to the flat portion 14, making it less likely for the structures to jam against each other. Furthermore, when the first inclined portion 214 abuts against the angle iron-like mechanism, the stability of the abutment can be further increased, thereby further increasing the stability of the assembly.

[0027] In this embodiment, the second card plate 12 is also provided with a second protruding strip 121, which is located on the side of the first protruding strip away from the frame material 1; a deformation pressing part 216 is also provided between the wave part 14 and the back shell 2; it also includes a light-diffusing plate 3 for covering the accommodating cavity, the deformation pressing part 216 and the second protruding strip press the two sides of the light-diffusing plate respectively, so that the light-diffusing plate 3 maintains a curved state; it is not understood that after the light source of the light-emitting component is processed by the light-diffusing plate 3, it can obtain a softer lighting effect. The deformation pressing part 216 and the second protruding strip squeeze the two sides of the light-diffusing plate to form a curved structural shape and maintain it. In this state, the overall illumination of the light source is softer and a larger illumination area can be obtained.

[0028] This application also provides a panel light, including any of the aforementioned frame structures and a light-emitting component housed within the frame structure; the panel light adopts any of the frame structures described in the foregoing embodiments, and therefore has the same implementation details or the same structural scheme as the frame structure, and thus has the same beneficial effects.

[0029] In this embodiment, the panel light of this application also includes a hanging member 4 with a mounting column, and the back shell 2 is provided with mounting holes adapted to be riveted to the mounting column; in a specific solution, the hanging member 4 can realize the installation of the panel light by combining the panel with the keel structure and then suspending the panel on the ceiling layer; and the mounting column and mounting holes can realize the quick assembly of the back shell and the hanging member 4, which greatly shortens the installation time of technicians; on another level, compared with the hanging member 4 composed of the first sheet and the second sheet in the previous embodiment, the hanging member 4 in this embodiment uses more material and is in a flat sheet shape, which has great convenience in transportation.

[0030] As an improvement of this application, it also includes a power supply component 5, with conductive parts provided on the side of the back shell; the power supply component 5 is mounted on the side of the back shell with conductive parts; the power supply component is electrically connected to the conductive parts. The power supply component 5 converts external power into a suitable voltage to drive the panel light. This part is prior art and will not be described in detail. In a further embodiment, the power supply component 5 has wing plates 51 at both ends. It is worth understanding that during the installation of the panel light, the power supply component 5 is often detachably connected to the panel light. Before the technicians hoist the panel light into a fixed position, they need to first fix the traditional power supply component 5 to the back shell 2 using a threaded structure, and then hoist it to the expected position. In this embodiment, the back shell 2 has a set of snap-fit ​​plates 22 on the side where the conductive parts 22 are formed. Part of any snap-fit ​​plate 22 fits against the side of the back shell 2, and the other part forms a snap-fit ​​gap. The wing plates 51 are inserted into the snap-fit ​​gaps. The wing plates 51 at both ends of the power supply component 5 are used to slide into the snap-fit ​​gaps, thus completing the assembly of the panel light and the power supply component 5. To facilitate installation and use by technicians and improve installation efficiency; in a further embodiment, the side of the snap-fit ​​plate forming the snap-fit ​​gap consists of a first snap-fit ​​wing 221 and a second snap-fit ​​wing 222. The gap formed by the first snap-fit ​​wing 221 is smaller than the gap formed by the second snap-fit ​​wing 222, and a movable opening 213 is formed between the first snap-fit ​​wing 211 and the second snap-fit ​​wing 212. The movable opening 223 can weaken the profile strength of the second snap-fit ​​wing 222 and can adjust it to a certain extent to better snap-fit ​​the wing plate 51. In this assembly method, the wing plate will be clamped in the gap formed by the first snap-fit ​​wing 221. When there is loosening in the vertical direction, the first snap-fit ​​wing 221 will abut against the interference wing plate 51, effectively preventing the power supply component 5 from coming out.

[0031] The advantages of this invention are: The slot and the snap-fit ​​flange work together to achieve a stable snap-fit ​​between the frame and the back shell, preventing easy separation. This eliminates the need for traditional screw-based fixing methods, simplifying the installation structure and enabling quick installation.

[0032] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
