Technical Field

[0001] This utility model relates to the field of elevator ceiling technology, and in particular to an electrically operated elevator ceiling system. Background Technology

[0002] As elevator interiors become increasingly complex, suspended ceilings with safety windows are gradually appearing on the ceiling panels. The current mainstream solution involves creating a 0.3m x 0.5m opening in the ceiling, enclosing it with angle iron on all four sides, and using a translucent panel or steel plate as a decorative panel on top. The procedure involves manually pushing the decorative panel upwards, placing it within the suspended ceiling, and then opening the safety window. While this solution is simple and low-cost, it has the following problems:

[0003] The decorative panel is fastened to the ceiling by angle iron. The decorative panel is recessed into the bottom of the ceiling, and the bottom of the ceiling is not flush. Because the position of the decorative panel is fixed in the ceiling, the style of the ceiling is limited.

[0004] The decorative panels are not fixed in the vertical direction. If the car shakes, the decorative panels themselves will make abnormal noises.

[0005] Therefore, there is an urgent need to design an electrically operated elevator ceiling system to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an electrically opening and closing elevator ceiling system with a flat bottom and stable structure.

One end of each rod assembly is connected to one side of the rotating wheel, and the other end of one rod assembly is connected to one of the decorative panels, and the other end of the other rod assembly is connected to the other decorative panel.

[0008] As an improvement to the above solution, the rod assembly includes an active rod, a passive rod, a connecting rod, and a rotating rod. The top of both ends of the decorative panel are provided with a first connecting part and a second connecting part. The active rod is hinged to the positioning plate. The rotating wheel is connected to the rotating rod to drive the rotating rod. The rotating rod, connecting rod, active rod, and first connecting part are hinged in sequence. One end of the passive rod is hinged to the positioning plate, and the other end is hinged to the second connecting part.

[0009] As an improvement to the above solution, the active rod includes a first rod, a second rod, and a third rod connected in sequence; the first rod is connected to a connecting rod, and the connection between the first rod and the second rod is hinged to the positioning plate; the third rod is hinged to the first connecting part.

[0010] As an improvement to the above scheme, the first and third members are parallel to each other; the angle between the second and first members is 45°-60°.

[0011] As an improvement to the above solution, the active rod is shaped like a "Z".

[0012] As an improvement to the above solution, the window is provided with a first inclined surface, one end of the decorative panel is provided with a second inclined surface adapted to the first inclined surface, and the other end of the decorative panel is provided with an adapting inclined surface for connecting with another decorative panel.

[0013] As an improvement to the above solution, the upper part of the first inclined surface extends in a direction close to the window, and the lower part of the first inclined surface contracts in a direction away from the window.

[0014] As an improvement to the above solution, a triangular lock is provided at the bottom of the ceiling panel. The triangular lock is used to trigger the motor to drive the electric opening and closing component to open and close.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0025] like Figure 1 and Figure 2 As shown, the electric opening and closing elevator ceiling system of this utility model includes a ceiling panel 1 with a window 11, two decorative panels 2 for covering the window 11, and an electric covering assembly 3 symmetrically arranged on opposite sides of the window 11.

[0026] The electric cover assembly 3 includes a positioning plate 31, an electric opening and closing assembly 32, and a motor (not shown in the figure) for driving the electric opening and closing assembly 32. The electric opening and closing assembly 32 is located on one side of the positioning plate 31, and the motor is located on the other side of the positioning plate 31.

[0027] The electric opening and closing assembly 32 includes a rotating wheel 321 and two rod groups 322. One end of each rod group 322 is connected to both sides of the rotating wheel 321, the other end of one rod group 322 is connected to one decorative panel 2, and the other end of the other rod group 322 is connected to another decorative panel 2.

[0028] The electric opening and closing elevator ceiling system of this utility model realizes the opening and closing of the decorative panel 2 by driving the electric opening and closing component 32 with a motor, avoiding the inconvenience of manual operation and improving the convenience and safety of use; at the same time, through the linkage structure of the rod group 322 and the wheel 321, the smooth opening and closing of the decorative panel 2 is ensured, improving the stability and reliability of the system, and the bottom of the ceiling is flat and the structure is stable.

[0029] The electric opening and closing assembly 32 is described below:

[0030] The rod assembly 322 includes an active rod 3221, a passive rod 3222, a connecting rod 3223, and a rotating rod 3224. The top of both ends of the decorative panel 2 are provided with a first connecting part 21 and a second connecting part 22. The active rod 3221 is hinged to the positioning plate 31.

[0031] The rotating wheel 321 is connected to the rotating wheel rod 3224 to drive the rotating wheel rod 3224. The rotating wheel rod 3224, the connecting rod 3223, the driving rod 3221 and the first connecting part 21 are hinged in sequence.

[0032] One end of the passive rod 3222 is hinged to the positioning plate 31, and the other end is hinged to the second connecting part 22.

[0033] It should be noted that by setting the rotary rod 3224 and the connecting rod 3223, the transmission structure of the electric opening and closing assembly 32 is optimized, so that the power of the motor can be transmitted to the active rod 3221 more efficiently, thereby driving the opening and closing action of the decorative panel 2, and improving the transmission efficiency and stability of the system.

[0034] like Figure 3 As shown, in terms of the specific structure of the active rod 3221, the active rod 3221 includes a first rod 3221a, a second rod 3221b, and a third rod 3221c connected in sequence;

[0035] The first rod 3221a is connected to the connecting rod 3223, and the connection between the first rod 3221a and the second rod 3221b is hinged to the positioning plate 31.

[0036] The third member 3221c is hinged to the first connecting part 21.

[0037] More preferably, the first member 3221a and the third member 3221c are parallel to each other;

[0038] The included angle ∠A between the second member 3221b and the first member 3221a is 45°-60°, preferably 60°.

[0039] The active rod 3211 is shaped like a "Z".

[0040] The electric opening and closing elevator ceiling system of this utility model optimizes the spatial layout of the rod group 322 by designing the active rod 3221 as a structure in which three rods are connected in sequence. This allows the decorative panel 2 to maintain stable movement during opening and closing, avoiding motion interference or jamming caused by unreasonable rod layout, and improving the system's operational stability and reliability.

[0041] like Figure 2 As shown, in order to facilitate the opening and closing of the decorative panel 2, the window 11 is provided with a first inclined surface 111, and one end of the decorative panel 2 is provided with a second inclined surface 23 that is adapted to the first inclined surface 111;

[0042] The other end of the decorative panel 2 is provided with an adapting bevel 24 for connecting with another decorative panel 2.

[0043] Preferably, the upper part of the first inclined surface 111 extends in a direction close to the window 11, and the lower part of the first inclined surface 11 tapers in a direction away from the window 11.

[0044] The electric opening and closing elevator ceiling system of this utility model is provided with a first inclined surface 111, a second inclined surface 23 and an adapting inclined surface 24. Through the cooperation between them, the gap between the decorative panel 2 and the window 11 is reduced, effectively avoiding the problem of light transmission and leakage, and improving the aesthetics and sealing of the ceiling. At the same time, the design of the adapting inclined surface 24 allows the two decorative panels 2 to be seamlessly connected, further optimizing the overall appearance of the ceiling.

[0045] like Figure 4 As shown, the length L of the window 11 is 0.65m-0.75m, and the width D of the window 11 is 0.45m-0.55m. Preferably, L=0.7m and D=0.5m.

[0046] It should be noted that, due to strength requirements, the existing manually operated decorative panel top plate can only meet the minimum national standard requirement of 0.5m x 0.3m, and cannot adopt the recommended standard (0.5m x 0.7m). Furthermore, a window of 0.5m x 0.3m is too narrow and unfriendly to people with larger builds. The electric opening and closing elevator ceiling system of this invention, being electrically operated and consisting of two decorative panels 2, allows the window 11 to adopt the recommended standard (0.5m x 0.7m), providing users with more space, facilitating entry and exit, and improving practicality.

[0047] Preferably, in order to enable direct control of the opening and closing of the decorative panel 2 from inside the elevator car, making the operation more convenient, a triangular lock (not shown in the figure) is provided at the bottom of the ceiling panel 1. The triangular lock is used to trigger the motor to drive the electric opening and closing component 32 to open and close. The specific principle of the triangular lock triggering the motor to drive the electric opening and closing component 32 to open and close is the prior art, and will not be described in detail here.

[0048] like Figure 1 As shown, the electric opening and closing elevator ceiling system of this utility model further includes a safety housing 4 disposed on the ceiling panel 1. The top of the safety housing 4 is provided with a safety window 41 and a safety plate (not shown in the figure) adapted to the safety window 41.

[0049] The safety plate is connected to a micro switch, which is used to trigger the motor to drive the electric opening and closing assembly 32 to open and close.

[0050] This utility model's electrically operated elevator ceiling system, by setting the safety window 41, safety plate, and micro switch, realizes the function of automatically triggering the opening and closing of the decorative panel 2 when the safety plate is opened from the outside of the elevator car, further improving the system's automation and safety, while also simplifying the operation process. The principle of the micro switch triggering the motor to drive the electrically operated opening and closing component 32 to open and close is existing technology and will not be described in detail here.

[0051] Preferably, the electric opening and closing assembly 32 further includes a position sensor (not shown in the figure) for detecting the position of the decorative panel 2. The position sensor is electrically connected to the motor and is used to control the motor to stop working when the decorative panel 2 reaches a preset position. By adding the position sensor, the position status of the decorative panel 2 can be monitored in real time, and the motor can be controlled to stop working in time when the decorative panel 2 reaches the preset position (fully open and fully closed), avoiding mechanical damage and energy waste caused by excessive motor operation, and improving the reliability and service life of the system.

[0052] In summary, the electric opening and closing elevator ceiling system of this utility model achieves the opening and closing of the decorative panel 2 by driving the electric opening and closing component 32 with a motor, avoiding the inconvenience of manual operation and improving the convenience and safety of use. Simultaneously, the linkage structure of the rod assembly 322 and the rotating wheel 321 ensures the smooth opening and closing of the decorative panel 2, improving the stability and reliability of the system, resulting in a flat ceiling bottom and structural stability. Furthermore, this electric opening and closing elevator ceiling system comprehensively improves the transmission efficiency, stability, safety, and service life of the electric opening and closing elevator ceiling system through optimization of the transmission structure, the layout of the rod assembly 322, the connection method, the slope design, the window size, the control method, and the addition of sensors, better meeting the actual usage needs of elevator ceilings.

[0053] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
