detailed description

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

In this application, the directional term "longitudinal" is indicated by arrow A in FIG. 1 , and the directional term “radial” is indicated by arrow B in FIG. 1 .

Figure 1 schematically shows a mounting structure 1 for a luminaire according to the present application. As shown in Figure 1. The mounting structure 1 includes a base assembly 100 and a joint assembly 200 cooperating with the base assembly 100 . The base assembly 100 includes a fixing body 101 , two retaining members 102 connected to the fixing body 101 , and an elastic pressing member 110 connected to the fixing body 101 , and the elastic pressing member 110 is located between the two retaining members 102 . The joint assembly 200 includes two hooks 202 and a pressing surface 210 between the two hooks 202 . The two hooks 202 are respectively snapped together with the corresponding retaining members 102 , and the elastic pressing members 110 are pressed against each other. Press surface 210.

When using the installation structure 1 shown in FIG. 1 , it is only necessary to snap together the two hooks 202 with the corresponding fasteners 102 to complete the assembly. After the mounting structure 1 is used in a light fixture, such as the light fixture 2 shown in FIG. 2 (for example, a ceiling light), the base assembly 100 can be pre-installed on the mounting base (for example, a ceiling), and the joint assembly 200 is mounted on on the lamp body 201 of the lamp 2 . In this way, only the hooks 202 need to be snapped together with the corresponding fasteners 102 to complete the installation of the lamp 2 . During the installation of the lamp 2, there is no need for fixing parts such as screws and rivets, so that the installation of the lamp 2 is greatly simplified and the operation is also very convenient. In addition, the elastic pressing member 110 pressing against the pressing surface 210 can make the clamping between the hook 202 and the corresponding retaining member 102 more stable, thereby making the installation of the lamp 2 more stable.

The structures of the base assembly 100 and the joint assembly 200 will be described in detail below.

As shown in FIG. 1 , the fastener 102 of the base assembly 100 includes an elastic base 103 connected to the fixing body 101 , and a radially bent buckle 104 is formed on the elastic base 103 . Correspondingly, the hook 202 includes a body 203 extending in the longitudinal direction, and a bayonet 204 in the radial direction is formed on the body 203 . In this way, the clasp 104 can be snapped into the corresponding bayonet 204 in the radial direction conveniently, and thus the detachable assembly of the base assembly 100 and the joint assembly 200 can be realized. Specifically, the elastic base 103 includes a first extending portion 105 in the radial direction and a second extending portion 106 in the longitudinal direction. The first extension part 105 is connected with the fixing body 101 , the second extension part 106 is connected with the first extension part 105 , and the hook 104 is formed on the second extension part 106 . In this way, by adjusting the radially extending length of the first extension portion 105, the coverage of the base assembly 100 can be adjusted, and thus, the mounting structure 1 of the present application can be conveniently used for lamps of various sizes.

As also shown in FIG. 1 , the two clasps 104 are radially opposed and extend in the same direction. For example, for a round luminaire, the two clasps 104 are at both ends of the same diameter; for a square luminaire, the two clasps 104 are at opposite ends of the diagonal; for other shapes of lamps, The settings of the two clasps 104 are also similar, and will not be repeated here. In this way, the two snap hooks 104 are snapped into the corresponding bayonet 204 from the same side of the bayonet 204 in the radial direction. As schematically shown in Fig. 3e, the hook 104 of the first clasp 1021 on the right side in Fig. 3e is snapped into the bayonet 204 radially to the left from the right side of the first hook 2021, in Fig. 3e The clasp 104 of the second clasp 1022 on the middle left is also clamped into the bayonet 204 radially to the left from the right side of the second clasp 2022 . With this structure, during assembly, it is not necessary to press both the first retaining member 1021 and the second retaining member 1022 radially inward to the inner side of the first hook 2021 and the second hook 2022 (ie, the first hook 2021 and the second hook 2022). A hook 2021 and a second hook 2022 on the opposite side), but on the same side of the first hook 2021 and the second hook 2022, and then push the joint assembly 200 toward the base assembly 100, the installation structure 1 can be realized. assembly. The assembly process is simple and easy to operate.

In a specific embodiment, the bending direction of the hook 104 and the elastic base 103 form an acute angle α (as shown in FIG. 5 ). It should be understood that in the case where the elastic base 103 includes a first extending portion 105 in the radial direction and a second extending portion 106 in the longitudinal direction, and the hook 104 is formed on the second extending portion 106, the bending of the hook 104 The folding direction forms an acute angle α with the second extending portion 106 . The inventors found that with this structure, the hooks 104 are snapped together with the corresponding bayonet openings 204 in a suspended manner, which can further ensure the snapping stability of the fasteners 102 and the corresponding snap hooks 202 . Specifically, the acute angle α may be between 60° and 88°. In this way, not only the clamping stability of the clasp 102 and the corresponding hook 202 can be ensured, but also the clasp 104 can be easily clamped into the bayonet 204 to ensure a simple assembly process and easy operation.

As also shown in FIG. 1 , the clasp 102 further includes a guide portion 107 extending obliquely from the clasp 104 , and the guide portion 107 guides the clasp 104 to be snapped into the bayonet 204 . In this way, under the guidance of the guide portion 107 , the buckle 104 can be snapped into the corresponding bayonet 204 more conveniently.

Look at the elastic pressing member 110 of the base assembly 100 . As shown in FIG. 1 , the elastic pressing member 110 is located between the two retaining members 102 . The joint assembly 200 includes a pressing surface 210, and the pressing surface 210 is located between the two hooks 202. After the hooks 104 are clipped into the corresponding bayonet 204, the elastic pressing member 110 presses the pressing surface 210 (eg, The body 20 of the lamp 2). The elastic pressing member 110 may be in the shape of a bar, so the elastic pressing member 110 and the pressing surface 210 are in line contact. In this state, the elastic pressing member 110 is pressed to apply a force away from the base assembly 100 to the pressing surface 210 (for example, a longitudinal force for a ceiling lamp). Therefore, the clasp 102 (or the clasp 104 ) and the clasp 202 (or the bayonet 204 ) are snapped together more closely, which further improves the clasping stability of the clasp 102 and the corresponding clasp 202 . After the installation structure 1 is applied to the lamp 2 , the elastic pressing member 110 presses the lamp body 20 of the lamp 2 , which can also prevent the lamp body 20 from rotating or deflecting, thereby improving the stability of the lamp 1 (or the lamp body 20 ).

The number of the elastic pressing members 110 is two and spaced apart in the radial direction. The first elastic pressing member 1101 is adjacent to the first retaining member 1021 of the two retaining members 102 , and the second elastic pressing member 1102 is adjacent to the second retaining member 1022 of the two retaining members 102 . In the assembled state, as shown in FIG. 3e , the first retaining member 1021 is clamped into its bayonet 204 from the radially outer side of the first hook 2021 of the two hooks 202, and the first elastic pressing member 1101 presses It is pressed against the pressing surface 210 and abuts against the body 203 of the first hook 2021 at the radial inner side of the first hook 2021 . The second elastic pressing member 1102 presses against the pressing surface 210 and is spaced apart from the two hooks 202 . In this way, the first elastic pressing member 1101 and the second elastic pressing member 1102 evenly apply pressure to the pressing surface 210 (or the lamp body 20 ), so that the pressing surface 210 (or the lamp body 20 ) is more stable. More importantly, the first elastic pressing member 1101 and the first retaining member 1021 are arranged opposite to each other in the radial direction and substantially clamp the first hook 2021, so that even if the engaging assembly 200 (or the lamp body 20) is pushed radially, The retaining member 102 (or the hook 104 ) and the hook 202 (or the bayonet 204 ) will not be disengaged, which further ensures the stability of the engagement between the base assembly 100 and the engaging assembly 200 .

In one embodiment, the extension length of the elastic pressing member 110 in the longitudinal direction is greater than the extension length of the retaining member 102 in the longitudinal direction. In this way, after the clasp 104 is snapped into the corresponding bayonet 204, the elastic pressing member 110 can be ensured to be in a compressed state, so as to exert a force away from the base assembly 100 on the pressing surface 210. The longitudinal extension length of the elastic pressing member 110 can be adjusted according to the actual situation, which will not be repeated here.

The first elastic pressing member 1101 and the second elastic pressing member 1102 each include a first extending portion 120 extending radially and a second extending portion 121 inclined radially outward. The first extension part 120 is connected with the fixing body 101 , the second extension part 121 is connected with the first extension part 121 , and the end of the second extension part 121 is bent radially outward in an arc shape. Specifically, the radial extension length of the first extension portion 120 of the first elastic pressing member 1101 is greater than the radial extension length of the first extension portion 120 of the second elastic pressing member 1102 . In this way, the end of the second extension portion 121 of the first elastic pressing member 1101 can press against the pressing surface 210 and abut against the body 203 of the first hook 2021 . In addition, the length of the first extension portion 120 can be adjusted according to the actual situation, so that the installation structure 1 has a wider scope of application, which will not be repeated here.

As also shown in FIG. 1 , the base assembly 100 further includes a side wall 130 located radially outside the two retaining members 102 , and correspondingly, the engaging assembly 200 includes a baffle 230 located radially outside the two hooks 202 . Side wall 130 and baffle 230 extend longitudinally toward each other. In this way, after the snap hooks 104 are snapped into the corresponding bayonet openings 204 , the side walls 130 are inserted between the corresponding snap hooks 202 and the baffle 230 . In this case, the hook 202 further includes a mounting portion 220 , the mounting portion 220 extends radially outward and is connected to the corresponding baffle plate 230 , and the body 203 is connected to the mounting portion 220 . In this way, in the assembled state, the baffle plate 230 surrounds the retaining member 102 , the hook 202 , the elastic pressing member 110 and the side wall 130 as a whole, so that accidental contact with the retaining member 102 , the hook 202 and the elastic pressing member can be avoided. The pressing piece 110 further improves the joint stability of the base assembly 100 and the joint assembly 200, and is more beautiful in appearance.

Also shown in Figure 1. The side wall 130 includes a first portion 1301 corresponding to the first retaining member 1021 and a second portion 1302 corresponding to the second retaining member 1022 . The longitudinal length of the second portion 1302 is smaller than the longitudinal length of the first portion 1301 . In this way, during the assembly process, there may be temporarily a larger gap between the second portion 1302 and the baffle 230 to facilitate precise operation by the operator (as described below), thereby making the assembly process simple and easy to operate.

The assembly and disassembly process of the installation structure 1 is described below by taking the lamp 2 shown in FIG. 2 as an example.

When assembling the mounting structure 1 , the base assembly 100 is first mounted on the ceiling 3 . Then, the lamp body 20 is inclined with respect to the longitudinal direction, so that there is a larger gap 31 between the second portion 1302 of the side wall 130 and the baffle 230 (as shown in FIG. 3 a ). The operator moves the first hook 2021 close to the first retaining member 1021 and the first elastic pressing member 1101 under observation through the gap 31 . After the first elastic pressing member 1101 is in contact with the first hook 2021 at the radial inner side, the lamp body 20 is rotated (for example, in the direction of arrow R in FIG. 3 a ) to the longitudinal direction and the lamp body 20 is pushed up longitudinally (as shown in FIG. 3 a ) 3b, 3c and 3d). In the state of FIG. 3 b , the first elastic pressing member 1101 has just been in contact with the first retaining member 1021 . In the state of FIG. 3 c , the lamp body 20 is moved longitudinally upward relative to the base assembly 100 , the first elastic abutting member 1101 and the second elastic abutting member 1102 are moved toward the lamp body 20 , and the first elastic abutting member 1101 is The first clasping member 1021 is generally pressed radially inward to be elastically deformed (as shown by the arrow F1 in FIG. 3c ). In the state of FIG. 3d , the lamp body 20 is further moved longitudinally upward relative to the base assembly 100 , the first elastic pressing member 1101 and the second elastic pressing member 1102 move to just contact the lamp body 20 , and the first elastic pressing member 1102 is at this moment. The member 1101 is still elastically deformed by being pressed substantially radially inward by the first retaining member 1021 (as indicated by arrow F1 in Figure 3d). Continue to push up the lamp body 20 longitudinally, so that the first clasp 1021 (or the clasp 104 ) is snapped together with the first clasp 2021 (or the bayonet 204 ), and the second clasp 1022 (or the clasp 104 ) Being snapped together with the second hook 2022 (or the bayonet 204 ), the first elastic pressing member 1101 presses the pressing surface 210 and abuts against the body of the first hook 2021 at the radial inner side of the first hook 2021 203 , the second elastic pressing member 1102 only presses the pressing surface 210 (as shown in FIG. 3 e ). In this way, the assembly of the mounting structure 1 is completed. In the state of FIG. 3e , the second elastic pressing member 1102 is elastically deformed by being pressed longitudinally upward by the lamp body 20, and the first elastic pressing member 1101 is pressed radially inward by the lamp body 20 and is The retaining member 1021 is pressed longitudinally upward and elastically deformed (as shown by arrows F1, F2 and F3 in FIG. 3e ), and the installation of the installation structure 1 or the lamp 2 is completed. Under the elastic force of the first elastic pressing member 1101 and the second elastic pressing member 1102, the base assembly 100 and the lamp body 20 are stably joined together.

When disassembling the installation structure 1, as shown in FIG. 4a, a force F toward the second hook 2022 is applied on the lamp body 20 (ie, in FIG. 4a, a leftward force is applied from the side close to the first hook 2021). F), to squeeze the first elastic pressing member 1101 and disengage the first retaining member 1021 (or the hook 104) from the first hook 2021 (or the bayonet 204), and the second retaining member 1022 (or clasp 104) disengages from second clasp 2022 (or bayonet 204). Then, the lamp body 20 is pulled down longitudinally until the engaging assembly 200 is completely separated from the base assembly 100 (see Figures 4b, 4c and 4d). In this way, the disassembly of the mounting structure 1 is completed.

It can be seen that the assembly and disassembly of the installation structure 1 according to the present application are very simple and easy to operate.

The above descriptions are merely examples of the present application, and are not intended to limit the present application. Various modifications and variations of this application are possible for those skilled in the art.
