Description

Technical Field

[0001] The utility model relates to the technical field of panel lamps, in particular to a clamping structure and a screwless panel lamp using the clamping structure. Background Art

[0002] LED panel lights are high-end indoor lighting fixtures with anodized aluminum alloy frames and LED light sources. The entire design is elegant, simple, and luxurious, delivering both excellent lighting effects and a sense of beauty. The unique design of LED panel lights creates a uniform, planar light pattern after light passes through a uniform light distribution plate. This produces uniform illumination, soft, comfortable light, and bright light, effectively alleviating eye fatigue.

[0003] Existing LED panel lights primarily use screws to secure the backplate to the frame. This method is time-consuming and inconvenient to assemble due to the large number of screws, resulting in low production efficiency and high labor intensity. Furthermore, the excessive number of screws increases the width of the lamp frame, increasing its weight and affecting the overall aesthetics of the panel light. A screwless panel light employing this structure is proposed to address these issues. Utility Model Content

[0004] The purpose of the utility model is to provide a snap-fit structure and a screwless panel lamp using the snap-fit structure, so as to solve the problems caused by the prior art that LED panel lamps mainly use screws to fix the back panel on the frame.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) A snap-fit structure in the present invention connects the edge of the groove on the back panel with the slot of the frame, thereby achieving screwless installation, improving production efficiency, and not affecting the appearance of the product.

DETAILED DESCRIPTION

[0028] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0029] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0030] like Figure 1 、 Figure 2As shown, a snap-fit structure includes: a mounting frame, a back plate 2 mounted on the mounting frame, and a light-distributing component. The mounting frame is formed by splicing multiple frames 1 end to end; Figure 5 As shown, each frame 1 has a supporting edge 6 extending inwardly, and a limiting member is provided on the outer side of the supporting edge 6 of the frame 1. The light-distributing assembly is placed on the supporting edges 6 of the multiple frames 1; and an elastic material is attached to the circumferential edge of the top surface of the light-distributing assembly.

[0031] like Figure 3 、 Figure 5 As shown, the back plate 2 is arranged above the light-distributing assembly, and the circumferential edge of the back plate 2 is bent to form a groove 7. The bottom of the groove 7 is pressed against the elastic material, thereby pressing the light-distributing assembly against the supporting edge 6. The edge of the groove 7 is engaged with the limiter to fix the back plate 2 on the mounting frame. Figure 3 As shown, the edge of the back panel 2 extends horizontally to form a first extension section 8, and the end of the first extension section 8 is bent upward to form a second extension section 9. The edge of the back panel 2, the first extension section 8, and the second extension section 9 together enclose a groove 7. The bottom surface of the groove 7 contacts the top surface of the elastomer material on the light-distributing component, pressing the light-distributing component against the supporting edge 6.

[0032] like Figure 4 、 Figure 5 As shown, the limiting member is a vertically arranged vertical plate 10, and the top end of the vertical plate 10 extends horizontally toward the inner side of the frame 1 to form a horizontal plate 11, and the end of the horizontal plate 11 continues to extend downward to form an inclined plate 12. The vertical plate 10, the horizontal plate 11, and the inclined plate 12 together enclose a card slot 13; the edge of the groove 7 presses against the card slot 13 to realize the card connection between the edge of the groove 7 and the card slot 13.

[0033] like Figure 4 As shown, the lower end of the frame 1 is a horizontal frame main board 5, and the inner part of the frame main board 5 is a supporting edge 6; the frame main board 5 is upwardly extended with a connecting plate 14, and the frame main board 5 and the connecting plate 14 are enclosed to form a cavity. The setting of the cavity can, on the one hand, reduce the weight of the frame 1, save materials, and make the panel light lightweight; on the other hand, it can increase the strength of the frame 1; the lower end of the vertical plate 10 partially overlaps with the connecting plate 14.

[0034] like Figure 5As shown, the top surface of the supporting edge 6 features a gradually descending slope 15 from the outside to the inside. The bottom surface of the light-distributing component contacts the highest point of the slope 15. This slope 15 causes the diffuser plate 3, mounted on the frame 1, to bulge slightly downward in the middle due to its own gravity, ensuring more uniform light transmission through the diffuser plate 3. A retaining plate 16 is positioned between the vertical plate 10 and the supporting edge 6 on the main frame 5 to prevent the diffuser plate 3 from rocking side to side and back and forth. The multiple frames 1 are secured end to end by welding; the elastomer material is EVA foam 4. In this embodiment, the light-distributing component is the diffuser plate 3.

[0035] The installation process of a snap-fit structure in the present invention is as follows: first, overlap the four peripheral edges of the diffuser plate 3 and place them on the supporting edges 6 on the inner sides of the four frames 1, press down the back panel 2, the EVA foam 4 is squeezed, and the groove 7 of the back panel 2 presses the diffuser plate 3 tightly against the supporting edge 6. At the same time, the edge of the groove 7 of the back panel 2 is snapped into the slot 13 of the frame 1, and the back panel 2 is released. The EVA foam 4 rebounds to a certain thickness, so that the edge of the groove 7 of the back panel 2 is snapped into the slot 13 more firmly.

[0036] It should be noted that, if the panel light is repaired later, the groove 7 is pressed down and the EVA foam 4 is squeezed. Since the length of the inclined plate 12 is short, after the groove 7 is lowered by one end, it is very easy to pull the edge of the groove 7 out of the card slot 13. As long as the edge of the groove 7 on one side of the back plate 2 is pulled out, the edges of the groove 7 on the other three sides can be easily pulled out. The clamping structure of the utility model is very convenient for assembly and disassembly.

[0037] The utility model also provides a screwless panel light: including the above-mentioned snap-fit structure, a light bar, and a driving element, wherein the light bar is adhered to the inner top of the back plate 2, the driving element is electrically connected to the light bar, and the driving element is used to control the light bar to emit light.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
