The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In an embodiment, as shown in fig. 1, 2, 3, and 4, the car ceiling for an elevator includes a box body 1 and a lamp (not shown) installed in the box body, a bottom wall of the box body has a horizontal transverse direction (i.e., an x direction in fig. 1) and a horizontal longitudinal direction (i.e., a y direction in fig. 1) perpendicular to each other, a plurality of light transmission openings 11 are opened on the bottom wall of the box body, the bottom wall extends towards the inside of the box body at two opposite sides of the horizontal transverse direction of each light transmission opening to form two first standing portions 12, and tops of the two first standing portions 12 are respectively bent to form first curled edges.

A mounting plate 2 is further provided at each light transmitting opening, and the mounting plate includes a mounting portion 21, a second upright portion 22, and a second bead.

In the height direction, the mounting portion 21 is located between the top edge and the bottom edge of the first standing portion 12; in horizontal, the installation department is in between two first upright portions and leaves the isolation clearance with each first upright portion between, and the installation department is equipped with light zone.

The second vertical portions are two portions and extend from two horizontally opposite sides of the mounting portion 21 toward the inside of the case.

The second turned edges are formed by bending the tops of the corresponding second upright parts at two positions, and each second turned edge is superposed on the first turned edge at the corresponding side.

In most suspended ceilings on the market, the light exit surface of the lamp is substantially flush with the bottom wall of the cabinet. From the pleasing to the eye angle of vision, the light that lamps and lanterns sent can hardly form the reflection in furred ceiling department, makes the furred ceiling lack obvious stereovision effect. From structural stability's angle, the plain noodles generally covers has the diffusion sheet that has certain thickness (prevent the warpage), and diffusion sheet itself has certain gravity, and the elevator can produce certain acceleration at the in-process that starts or stops in addition, and the suspended ceiling diapire around the diffusion sheet can be pressed gradually and become shape after long-term the use, and the diapire no longer is the plane when installing originally, not only influences the pleasing to the eye degree of suspended ceiling, but also has certain potential safety hazard.

The suspended ceiling box body in the embodiment can be regarded as a housing sealed at the periphery of the lamp, the bottom wall of the box body is divided into a light-transmitting area and a light-tight area, and the light-transmitting area and the light-tight area are horizontally and alternately arranged along the horizontal direction, so that the richness and flexibility of the decorative lamp are improved, and the decorative lamp cannot be too messy.

The light-transmitting area is used for installing the light-diffusing plate, the installation part is positioned between the top edge and the bottom edge of the first standing part, and the installation position of the light-diffusing plate is higher than the bottom wall of the suspended ceiling, so that light emitted by the lamp in the box body can be reflected at the first standing part 12, and the visual stereoscopic impression is increased. By providing an isolation gap between the mounting portion 21 and the first upright portion 12, the three-dimensional appearance of the ceiling bottom portion is further increased.

In addition, the extending direction of the first upright part 12 and the second upright part 22 is basically vertical to the bottom wall of the suspended ceiling, the effect similar to a reinforcing rib is achieved, the bottom wall is prevented from bending and deforming, and the structural strength of the bottom wall is higher, and the suspended ceiling is safe and reliable.

The second bead is superposed on the first bead on the respective side, where the superposition differs from the superposition of the flat plates, which are generally limited to each other only in the height direction. The embodiment is the overlapping of the hems, and the structure of the hems means that the hems have a certain extension length in the height direction (relative to the bottom surface), and the overlapping of the extension lengths can prevent the two hems from horizontally and transversely dislocating each other, so that the structure is more stable.

The box body and the mounting plate can be formed by bending through a sheet metal process, the weight of the suspended ceiling of the lift car is reduced, the influence on the balance coefficient of the elevator traction system is small, and the elevator traction system is safe and reliable.

In order to facilitate replacement of the mounting plate, in one embodiment, the first curled edge includes a first horizontal portion 13 and a third vertical portion 14 which are formed by bending in sequence, the first horizontal portion 13 is formed by extending the top edge of the first vertical portion 12 in the horizontal direction, and the third vertical portion 14 is formed by extending the edge of the first horizontal portion 13 downward.

The first horizontal portion 13 is fixed to the mounting plate, and is used for bearing the weight of the mounting plate, increasing the contact area and preventing stress concentration. The third upright part 14 is pressed against the horizontal side of the second bead to prevent the mounting plate from swaying horizontally and transversely.

The car furred ceiling of this embodiment is when needs maintenance or change mounting panel, and the maintenance personal that can be through car inside directly is ejecting up the mounting panel, breaks away from first turn-up, then takes out from light-transmitting opening, and it is convenient to dismantle.

For maintenance convenience, in one embodiment, as shown in fig. 4, the two first flanges are respectively located at two opposite sides of the two first upright portions; the two second turned edges are respectively positioned at two opposite sides of the two second vertical parts. During processing, the top of the first upright portion 12 is bent in a direction away from the light-transmitting opening 11 to form a first curl, and the top of the second upright portion is bent in a direction away from the mounting portion 21 to form a second curl. This setting can avoid the top of installation department to be sheltered from by the turn-up, and when the diffusion sheet on the light zone is being changed to needs, the diffusion sheet can not be because of being blocked and unable the taking out by the turn-up, and it is more convenient to maintain.

The second hemming comprises a second horizontal part 23 and a fourth vertical part 24 which are formed by bending in sequence, the two second horizontal parts 23 are attached to the top surface of the corresponding side first horizontal part 13 in an abutting mode, the two fourth vertical parts 24 are attached to the outer side of the corresponding side third vertical part 14 in an abutting mode, and the mounting plate is fixed to the first hemming through a fastening piece penetrating through the first horizontal part 13 and the second horizontal part 23.

The mounting plate and the first crimping are connected through the fastener in a reinforcing mode, and structural stability can be further improved. In the above embodiments, in order to highlight the three-dimensional visual effect of the suspended ceiling, an isolation gap is provided between the mounting portion and the first upright portion. In this embodiment, the isolation gap is embodied as: in the horizontal transverse direction, the extension length of the second horizontal portion 23 is greater than the extension length of the first horizontal portion 13. A part of the second horizontal portion 23 is made to fit against the top surface of the first horizontal portion 13 so as not to be visible to passengers in the car, and another part of the second horizontal portion 23 is suspended above the isolation gap so as to be visible to passengers in the car. The fastener runs through first horizontal portion 13 and second horizontal portion 23, and the position of fastener corresponds to the position of first horizontal portion 13, and the below of fastener is sheltered from and is not visible to the passenger by first upright portion 12 and the bottom wall of box, has both played the effect of reinforcing furred ceiling structure, has not influenced the outward appearance of furred ceiling again.

Further, in one embodiment, as shown in fig. 3 and 4, the top of the light-transmitting area is covered with a light-transmitting plate 25; an avoidance gap 26 for adjusting the posture of the light-transmitting plate is left between the second horizontal part and the top wall of the box body.

The light transmitting area is an opening area formed in the mounting portion, and the light transmitting plate 25 is one of the light diffusing plates. The horizontal dimension of light-transmitting plate 25 is greater than the horizontal dimension of light-transmitting area, makes light-transmitting plate 25 can not fall from the light-transmitting area when the elevator normally works. When the light-transmitting plate 25 needs to be taken out in the maintenance process, the light-transmitting plate 25 can be firstly pushed out of a groove-shaped space formed by the mounting plates, then the rotating angle of the light-transmitting plate 25 is adjusted in the space formed by the avoiding gap 26, and the light-transmitting plate 25 can be taken out from the light-transmitting area after the space posture of the light-transmitting plate 25 is adjusted.

In order to improve the light energy utilization efficiency, in one embodiment, a plurality of light emitting elements (not shown) are mounted on the inner side of the top wall of the box body, and the positions of the light emitting elements correspond to the positions of the light transmission openings respectively. This arrangement can increase the ratio of the luminous flux passing through the light-transmitting region to the total luminous flux generated by the light-emitting element, thereby saving energy.

Specifically, in one embodiment, as shown in fig. 3, the bottom wall includes a plurality of four strip-shaped plates 15 arranged horizontally and horizontally at intervals, a gap between two adjacent strip-shaped plates 15 is a light-transmitting opening, and two first upright portions are respectively formed by extending opposite sides of two adjacent strip-shaped plates 15; the three mounting plates are respectively arranged at the three light transmitting ports; the bottom surfaces of the four strip-shaped plates are parallel and level with each other, and the bottom surfaces of the three mounting plates are parallel and level with each other and higher than the bottom surfaces of the strip-shaped plates.

The first upright part 12 of bar 15 and bar 15 both sides is same panel beating bending type, decomposes the diapire into the polylith panel beating, has made things convenient for processing and transportation, is favorable to reduction in production cost. The strip-shaped plates are parallel and level with each other, and the mounting plates are parallel and level with each other, so that the appearance is more attractive. The bottom surface through setting up the mounting panel is higher than the bottom surface of bar shaped plate and has strengthened the third dimension of furred ceiling.

In order to seal the side walls of the suspended ceiling and achieve the purpose of preventing the light leakage of the side walls, in one embodiment, as shown in fig. 2 and 5, in the horizontal longitudinal direction, two opposite side edges of the strip-shaped plate extend upward and respectively form two first side walls 31, and two opposite side edges of the mounting portion extend upward and respectively form two second side walls 32; the two opposite side walls of the box body along the horizontal longitudinal direction are respectively formed by alternately sealing and splicing the corresponding first side wall 31 and the second side wall 32; the two opposite side walls of the box body along the horizontal direction are respectively formed by extending the two opposite side edges of the corresponding strip-shaped plates upwards.

As shown in fig. 4, in order to obtain a three-dimensional visual effect, the bottom of the box body is formed with a groove and a protrusion with high and low heights, and the suspended ceiling is formed by alternately splicing and assembling a sheet metal part where the strip-shaped plate is located and a sheet metal part where the mounting plate is located during actual processing. In the assembling process, how to ensure that the bottom surface of the suspended ceiling has no obvious splicing gap, the side surface of the suspended ceiling has no obvious splicing gap, the bottom surface and the side surface of the suspended ceiling have no obvious splicing gap, and the outer surface of the suspended ceiling has no obvious convex thorns is considered by a designer.

To solve the splicing problem, in one embodiment, as shown in fig. 1, 2, 6, 7 and 8, the second sidewall 32 is provided. The first side wall 31 is divided into an upper half 311 and a lower half 312 of unequal widths. The lower half section 312 extends in the horizontal transverse direction to be adjacent to the second upright portion 22, and the upper half section 311 extends in the horizontal transverse direction to be adjacent to the edge portion of the corresponding second side wall 32 to close the separation gap to cause the patchwork. The side edge of the lower half 312 is adjacent to the side edge of the second upright portion 22 to close the side periphery above the mounting portion 21. The portion of the upper half 311 extending beyond the lower half 312 in the horizontal lateral direction forms a hanging portion 313. One side of the hanging portion 313 is attached to a side edge of the second horizontal portion 23 in the horizontal longitudinal direction to seal the lower surface (a part of the outer contour of the box) of the ceiling box. In the height direction, the bottom edge of the hanging portion 313 is flush with the bottom surface of the second horizontal portion 23 to avoid forming the burs, ensuring the beauty of the ceiling.

Further, in one embodiment, the thickness of the mounting plate is consistent with that of the strip-shaped plate. When the side edge of the second upright part 22 is seamlessly spliced with the side surface close to the second side wall 32, and the side edge of the second horizontal part 23 is seamlessly spliced with the side surface close to the hanging part 313, the outer surface of the hanging part 313 is just level with the outer surface of the second side wall 32, so that light leakage can be effectively prevented, the flatness of the outer contour of the box body is guaranteed, and the box body is more attractive.

In one embodiment, as shown in fig. 3 and 5, two reinforcing strips 4 are further arranged in the box body, and both the reinforcing strips extend horizontally and transversely and are oppositely arranged horizontally and longitudinally; the reinforcing bar has a first upright wall 41, and the first side wall and the second side wall are both attached to the outside of the first upright wall 41. The bottom edge of the first upright wall 41 horizontally extends towards the interior of the box body to form a reinforced bottom wall 42; the reinforced bottom wall is fixed against the top surface of the second horizontal portion 23.

The extending directions of the first upright part 12 and the second upright part 22 are longitudinally consistent with the horizontal direction, the extending direction of the first upright wall 41 is transversely consistent with the horizontal direction, and the first upright wall and the horizontal direction are matched with each other, so that the structural strength of the bottom of the suspended ceiling is improved, and the bottom surface of the suspended ceiling is prevented from being arched and deformed. Between the sheet metal component at mounting panel and the bar shaped plate place that the interval was arranged, except that connecting into a monoblock through the fastener that runs through first horizontal part and second horizontal part, still connect into a monoblock through two reinforcing strips 4. Specifically, the first side wall 31 and the second side wall 32 are fixed at different positions of the first vertical wall 41 through fasteners except for the side walls of the suspended ceiling box body which are horizontally and transversely spliced into a non-obvious gap, and the stability of the suspended ceiling bottom structure is further improved. In addition, the reinforcing bottom wall 42 is directly attached to the top of the second horizontal portion 23, so that the first vertical wall 41 functioning as a transverse reinforcing rib directly abuts against the first side wall 31 or the second side wall 32 functioning as a longitudinal reinforcing rib, and the suspended ceiling has higher deformation resistance.

The reinforcing strips 4 are arranged on the inner sides of the first side wall 31 and the second side wall 32, namely the reinforcing strips 4 are arranged inside the box body of the suspended ceiling and are invisible to passengers in the cage, so that the attractiveness of the suspended ceiling is guaranteed. Further, in one embodiment, the fasteners are positioned adjacent to the top of the first side wall 31 or the second side wall 32, so that even if a gap is left between the side walls of the ceiling box and the wall of the car, the fasteners are not exposed to the view of passengers, further ensuring the aesthetics of the ceiling.

In order to reduce the shaking of the light-transmitting plate, in one embodiment, as shown in fig. 3, 9 and 10, the three light-transmitting openings include a middle light-transmitting opening and edge light-transmitting openings respectively arranged at two sides of the middle light-transmitting opening; the horizontal side of the reinforcing bottom wall extends upwards to form a second vertical wall 43, the second vertical wall 43 is arranged opposite to the first vertical wall 41, and a limiting plate 5 extending downwards is attached and fixed on the horizontal inner side of the second vertical wall 43. The two limiting plates 5 correspond to the positions of the light-transmitting openings at the two edges respectively. The light-transmitting plate 25 is limited by abutting against the second upright part 22 on the corresponding side along two opposite sides in the horizontal transverse direction. The two opposite sides of the light-transmitting plate 25 along the horizontal and longitudinal directions are respectively abutted against the two limiting plates 5 for limiting.

In this embodiment, the horizontal side edge of the light-transmitting plate 25 is selected to abut against the second vertical part 22 or the limiting plate 5 for limiting in the fixing mode of the light-transmitting plate 25, so that the influence on the appearance caused by the fixing of the fastening piece is avoided, and the light-transmitting plate is convenient to detach. For example, in one embodiment, the pretightening force of the second vertical part 22 for clamping the horizontal and horizontal opposite sides of the light-transmitting plate 25 is smaller, the pretightening force of the limiting plate 5 for clamping the horizontal and vertical opposite sides of the light-transmitting plate 25 is larger, and the light-transmitting plate 25 is clamped and disassembled by the elastic deformation of the limiting plate 5, so that the replacement by a maintenance worker is facilitated.

In order to make the distribution form of the lamp beautiful, in one embodiment, as shown in fig. 1, the size of the central light-transmitting opening is 8-10 times that of the edge light-transmitting openings in the horizontal transverse direction. Because the size of the middle light-transmitting opening is overlarge, the mounting plate corresponding to the position of the middle light-transmitting opening cannot adopt the form of opening a hollow area on the integrated plate like the mounting plate corresponding to the position of the edge light-transmitting opening. If the mounting panel corresponding to middle part printing opacity mouth also adopts the panel beating processing technology of integral type, not only cause the difficulty for processing and transportation, even process its structural strength and also be difficult to guarantee.

In order to ensure the structural strength of the mounting plate corresponding to the central light-transmitting opening, in one embodiment, as shown in fig. 5, 11 and 12, the mounting plate corresponding to the central light-transmitting opening has a frame structure including two transverse edges 6 and two longitudinal edges 7. The transverse edge 6 comprises a transverse edge vertical wall 61 attached and fixed to the outer side of the first vertical wall 41, the top edge of the transverse edge vertical wall 61 is flush with the top of the first vertical wall 41, the length of the downward extension of the bottom edge of the transverse edge vertical wall 61 exceeds the bottom of the first vertical wall 41, the bottom of the transverse edge vertical wall 61 extends horizontally towards the inside of the box body to form a transverse edge bottom wall 62, and the transverse edge bottom wall 62 is located below the reinforced bottom wall 42. The edge part of the lateral side bottom wall 62 extends upwards to form a supporting standing wall 63, and the reinforcing bottom wall 42 is lapped on the top surface of the supporting standing wall 63. The position of the middle light-transmitting opening corresponds to that of the large light-transmitting plate 8, and the two horizontal and longitudinal opposite sides of the large light-transmitting plate 8 are respectively propped against the second vertical wall 43 of the corresponding side for limiting.

The longitudinal side 7 comprises a longitudinal side vertical wall 71, and the longitudinal side vertical wall 71 is fixedly inserted with the transverse side 6. Specifically, the horizontal and transverse ends of the transverse side 6 are provided with slots 64, and the slots 64 penetrate through the transverse side vertical wall 61, the transverse side bottom wall 62 and the supporting vertical wall 63 in the horizontal and longitudinal directions. The insertion groove 64 passes through the bottom portions of the lateral standing walls 61 and the supporting standing walls 63 in the height direction with a gap from the top edges of the supporting standing walls 63. Notches matched with the height of the slot 64 are formed in the two ends of the vertical side vertical wall 71 in the horizontal and longitudinal directions, so that when the vertical side vertical wall below the notches is inserted into the slot 64, the top edge of the rest part of the vertical side vertical wall is flush with the top edge of the supporting vertical wall 63, and the large light-transmitting plate 8 is overlapped on the vertical side vertical wall 71 and the supporting vertical wall 63.

The bottom edge of the vertical side standing wall 71 extends back to the large light-transmitting plate 8 to form a vertical side bottom wall 72, and the horizontal side edge of the vertical side bottom wall 72 extends upwards to form a middle standing wall 73. The longitudinal side bottom wall 72 extends horizontally and transversely beyond the lateral side 6 so that the intermediate upright wall 73 abuts against the horizontal side edge of the lateral upright wall 61 to form a seal. When the first side walls 31 have the same processing dimension, a gap is formed between the lateral side standing wall 61 and the adjacent first side wall 31 due to the presence of the intermediate standing wall 73, and the gap is blocked by the first standing wall 41 to prevent light leakage.

The top of the middle standing arm 73 is bent toward the first bead to form a third bead superposed on the first bead, and the fixing manner of the third bead and the first bead is performed according to the fixing manner of the second bead and the first bead, so that the detailed description is omitted.
