[0018] Example 1

[0019] Figure 1 It is a three-dimensional diagram of a downlight fixing structure according to an embodiment. Figure 2 yes Figure 1 A three-dimensional view of the central spring and the downlight housing separated. Figure 1 as well as Figure 2, the downlight fixing structure 100 includes a downlight housing 105, a spring 101 and a spring 102, and the spring 101 and the spring 102 have the same structural arrangement. The downlight housing 105 has a slot structure 106 and a slot structure 107, and the slot structure 106 and the slot structure 107 have the same structural arrangement. The downlight housing 105 is used to accommodate a light source assembly (not shown in the figure). The slot structure 106 and the slot structure 107 are located on the side of the downlight housing 105. In this embodiment, the slot structure 106 and the slot structure 107 are symmetrically arranged on both sides of the downlight housing 105. The spring 101 includes a spring coil 108, a head end 103 and a tail end 104. In some embodiments, the length of the tail end 104 is longer than that of the head end 103. The head end 103 and the tail end 104 are rectangular in shape, and the head end 103 and the tail end 104 are formed by bending the metal wire forming the spring. The spring coil 108, the head end 103 and the tail end 104 of the spring 101 are formed by the same metal wire. In this embodiment, the downlight housing 105 is made of plastic material. In other embodiments, the downlight housing 105 may also be made of metal.

[0020] One end of the head end 103 of the spring 101 extends into the space inside one side of the spring coil 108, and the other end of the head end 103 is directly connected to the spring coil 108. One end of the tail end 104 of the spring 101 extends into the space inside the other side of the spring coil 108, and the other end is directly connected to the spring coil 108. In some embodiments, the portion of the head end 103 extending into the interior of one side of the spring coil 108 reaches 5 mm, and the portion of the tail end 104 extending into the interior of the other side of the spring coil 108 reaches 5 mm. The plane formed by the head end 103 of the spring 101 and the plane formed by the tail end 104 form an acute angle. When the head end 103 and the tail end 104 are pulled apart, due to the elastic force of the spring coil 108, the entire spring 101 will have an inward resistance, and this resistance can fix the downlight to the ceiling or wall. Refer to Figure 2 When assembling the downlight, the spring 101 and the spring 102 can be directly inserted into the slot structure 106 and the slot structure 107 in the direction 109 respectively.

[0021] Figure 3 yes Figure 1 The cross-sectional view of the downlight fixing structure along the AA line is shown. Figure 2 and Figure 3, the slot structure 106 has a notch 110. The head end 103 of the spring 101 can be directly inserted into the slot structure 106 through the notch 110. In some embodiments, the slot structure 106 has a protrusion structure 111. The protrusion structure 111 is an inward protrusion. When the head end 103 of the spring 101 is inserted into the slot structure 106, the protrusion structure 111 can help fix the head end 103 so that the head end 103 will not loosen upward. In other words, the protrusion structure 111 can clamp the head end 103. In some embodiments, the protrusion structure 111 is a hook structure that can hook and fix the head end 103. In some embodiments, there are grooves on both sides and below the protrusion structure 111. In other words, there are longitudinal gaps 112 on both sides of the protrusion structure 111, and there is a transverse gap 113 below the protrusion structure 111. The longitudinal gap 112 and the transverse gap 113 can make the protrusion structure 111 more elastic because the protrusion structure 111 will have a larger elastic bending amplitude. In some embodiments, the width of the longitudinal slit 112 is preferably 1 mm, and the width of the transverse slit 113 below the raised structure 111 is preferably 2 mm. In some embodiments, there are no grooves on both sides of the raised structure 111. In some embodiments, there are no grooves below the raised structure 111. In some embodiments, the raised structure 111 is a part of the downlight housing 105, and the raised structure 111 and the downlight housing 105 are integrally formed and use the same material.

[0022] Since the protrusion structure 111 is elastic, the head end 103 of the spring 101 can be directly inserted into the slot structure 106 by automated equipment to fix the spring 101. In this way, automated installation can be achieved and labor costs can be reduced.

[0023] Example 2

[0024] Figure 4 It is an exploded view of a downlight fixing structure of another embodiment. Figure 5 yes Figure 4 The following is a schematic diagram of the assembled downlight fixing structure. Figure 4 and Figure 5The downlight fixing structure 200 includes a downlight housing 40, two springs 20 and two spring fixing covers 30. The spring fixing cover 30 is fixed to the side of the downlight housing. The spring fixing cover 30 is in the shape of a sheet as a whole. A recessed portion 302 is provided on one side of the spring fixing cover 30. The left and right ends of the recessed portion 302 are integrally connected with the spring fixing cover 30. The upper and lower ends of the recessed portion 302 have slots, so that the recessed portion 302 and the spring fixing cover 30 together form a through slot 301 with openings at both ends. A buckle 303 is provided at the bottom of the spring fixing cover 30 corresponding to the position of the through slot 301. The spring fixing cover 30, the recessed portion 302 and the buckle 303 are integrally made. The spring 20 includes a spring coil 208, a head end 203 and a tail end 204. The head end 203 and the tail end 204 are rectangular in shape, and the head end 203 and the tail end 204 are formed by bending the metal wire forming the spring. In some embodiments, the length of the tail end 204 is longer than the head end 203. The spring coil 208, the head end 203 and the tail end 204 of the spring 20 are formed by the same metal wire. One end of the head end 203 of the spring 20 extends into the space inside one side of the spring coil 208, and the other end of the head end 203 is directly connected to the spring coil 208. One end of the tail end 204 of the spring 20 extends into the space inside the other side of the spring coil 208, and the other end of the tail end 204 of the spring 20 is directly connected to the spring coil 208. The head end 203 of the spring 20 extends into the through slot 301, and the head end 203 is clamped by the buckle 303, so that the head end 203 is fixed in the through slot 301 by the limit position, and will not be loosened from the spring fixing cover 30.

[0025] Please refer to Figure 4 , the interior of the downlight housing 40 has a accommodating cavity (not shown in the figure) with an opening facing downward, and the accommodating cavity is used to place a light source assembly (not shown in the figure). The downlight housing 40 can be made of metal or plastic. In the present embodiment, it is preferably made of metal. The material of the spring fixing cover 30 can be metal or plastic. In the present embodiment, it is preferably made of metal. In some embodiments, the downlight housing 40 and the spring fixing cover 30 are made of stainless steel plates, and the thickness of the stainless steel plates is about 1 mm. The two spring fixing covers 30 are fixed to the two sides of the downlight housing 40 by spot welding. Preferably, the two spring fixing covers 30 are symmetrically arranged on the two sides of the downlight housing 40.

[0026] Figure 6 yes Figure 5 The cross-sectional view of the downlight fixing structure shown is along the BB line. Figure 6 A first local structure 404 and a second local structure 405 are included. Figure 7 yes Figure 6An enlarged view of the first partial structure 404 of the cross-sectional view is shown. Figure 8 yes Figure 6 An enlarged view of the second partial structure 405 of the cross-sectional view is shown.

[0027] Reference Figures 4 to 7 , the first local structure 404 includes a recessed portion 302 of the spring fixing cover 30 and a buckle 303. The upper end of the buckle 303 is connected to the spring fixing cover 30, and the buckle 303 has slots on the left, right and bottom. The buckle 303 is roughly a sheet-like structure that gradually bends inward from top to bottom. In this way, the buckle 303 has an elastic bending function. When the front end portion 2031 of the head end 203 of the spring 20 reaches the bottom of the buckle 303, since the buckle 303 is elastic and there is space below the buckle 303, the front end portion 2031 of the head end 203 of the spring 20 will directly snap into the space below the buckle 303. In this way, the head end 203 of the spring 20 is fixed by the buckle and will not loosen.

[0028] Reference Figures 4 to 8 , the second local structure 405 includes a recessed portion 302 and a buckle 303 of the spring fixing cover 30. When the front end portion 2031 of the head end 203 of the spring 20 reaches below the buckle 303, since the buckle 303 is elastic and there is space below the buckle 303, the front end portion 2031 of the head end 203 of the spring 20 will directly snap into the space below the buckle 303. In this way, the head end 203 of the spring 20 is fixed by the buckle and will not loosen. In some embodiments, the buckle 303 has a barbed hook structure, which can clamp the head end 203 of the spring 20 more firmly. During the assembly production process, the front end 203 of the spring 20 can be well fixed after being inserted into the through slot 301 of the spring fixing cover 30 by automated equipment, thereby realizing automated installation.
