[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] like Figure 1 and 2 As shown, a double-layer ceiling for an elevator car includes a frame 100, wherein the frame 1 is composed of four frame strips. Figure 3-7As shown, the border strips include an upper border strip 1 and a lower border strip 2. The upper border strips 1 are spliced ​​to form an upper border, and the lower border strips 2 are spliced ​​to form a lower border. There is a gap between the upper border and the lower border. In one embodiment, a connecting piece 3 connecting the upper border strip 1 and the lower border strip 2 is arranged between the two.

[0036] In the present invention, the upper border strip 1, the lower border strip 2 and the connecting piece 3 are all made of bent metal sheets, wherein the upper border strip 1 is provided with a first folded edge 11 and a second folded edge 12 on both sides, the first folded edge is an inner folded right-angled edge, and the second folded edge 12 is an outer folded right-angled edge.

[0037] A first connecting corner piece 51 and a second connecting corner piece 52 are provided between adjacent upper frame strips 1, wherein the first connecting corner piece is provided at the outer corner of the upper frame, and the second connecting corner piece 52 is provided at the inner corner of the upper frame. In order to improve the strength, a reinforcing rib 10 is connected between two opposing upper frame strips, and the two ends of the longitudinal reinforcing rib 10 are in contact with the upper surface of the first folded edge 11, and the two ends of the transverse reinforcing rib 10 are in contact with the lower surface of the first folded edge 11.

[0038] The first connecting angle piece 51 is provided with a hanging seat 50, and the hanging seat 50 is provided with a through hole. A vertical hanging rod 5 is passed through the through hole. The hanging rod 5 is a threaded rod and is sleeved with a nut. By adjusting the position of the nut, the length of the hanging rod 5 above the hanging seat 50 can be adjusted.

[0039] The edges of both sides of the connecting member 3 have a third folded edge 31 and a fourth folded edge 32, the third folded edge 31 is connected to the second folded edge 12, and the fourth folded edge 32 is connected to the lower frame 2. The lower frame has a fifth folded edge 21 and a sixth folded edge 22, the fourth folded edge 32 is a right-angled folded edge, part of which is in contact with the fifth folded edge 21, and the sixth folded edge 22 is connected to the decorative plate 4.

[0040] In one embodiment, the edge of the decorative panel 4 has a seventh folded edge, which cooperates with the sixth folded edge 22, and four mounting holes 40 are arranged in the middle. Downlights 41 are arranged in the mounting holes 40, and the downlights 41 are bonded and fixed to the decorative panel 4 by glue.

[0041] In one embodiment, an inner decorative strip 24 and an outer decorative strip 23 are respectively provided on the inner and outer sides of the lower border strip 2, and the inner and outer decorative strips are spliced ​​to form a frame structure. The outer decorative strip 23 is higher than the fourth folded edge and the fifth folded edge, that is, higher than the lower border strip 2, and has a shielding effect on it.

[0042] Because the fifth folded edge 21 and the sixth folded edge 22 are folded inward, the lower frame strip 2 is sunken to form a groove, and a bracket 6 is installed in the groove. The bracket 6 is a W-shaped structure, with horizontal folded edges 61 on both sides, which is used to carry the light-transmitting plate 8, and a bulge in the middle to form an arched support portion 62, on which a buckle 70 is installed, and the buckle 70 is used to fix the light bar 7. The width of the bracket 6 is substantially equal to the spacing between the outer decorative strip 23 and the connecting member 3, so the movement of the light-transmitting plate 8 can be restricted. In addition, the outer decorative strip 23 is substantially flush with the light-transmitting plate 8, forming a visual effect of light-transmitting embedded in the lower frame strip 2.

[0043] The light bar 7 emits light toward the upper frame bar 1. The light emitted by the light bar 7 passes through the light-transmitting plate 8 and is projected onto the lower surface of the lower frame bar 1, causing diffuse reflection, and is projected onto the entire car space from the opening of the gap.

[0044] The inner decorative strip 24 has a protrusion which is inserted into the wall surface of the lower frame strip 2 to fix itself.

[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
