Abstract
Description
Technical Field
[0001] This application relates to the field of elevator technology, and in particular to a ceiling structure and an elevator. Background Technology
[0002] The ceiling structure of an elevator typically houses the installation and wiring for lighting, ventilation, and other functional equipment. Disassembly and reassembly of the ceiling are unavoidable when servicing light source components, cleaning filters, or performing other maintenance. Currently, most elevator ceiling structures on the market use a four-corner fixing method, where bolts are installed at each of the four corners to secure the entire ceiling to the car ceiling. Using this connection method, when replacing or repairing lighting fixtures, auxiliary fans, or other devices embedded in the ceiling, it is often necessary to remove all the bolts securing the ceiling. Because of the large number of bolts distributed at the four corners, at least two or more people are usually required to work together to prevent the ceiling from sagging or being damaged due to uneven force distribution during disassembly, posing a safety hazard and wasting manpower. Furthermore, when reinstalling the ceiling, the entire ceiling needs to be supported to a predetermined height and the bolt holes repeatedly aligned; especially when there are many bolts and their locations are scattered, this requires prolonged support of the ceiling, making the process cumbersome and labor-intensive, posing safety and efficiency risks. Therefore, the frequent and tedious disassembly and assembly work of traditional suspended ceiling structures, whether for daily maintenance or temporary repairs, significantly increases the demand for manpower and time, which not only increases operating and maintenance costs but also brings additional burdens to later management. Utility Model Content
[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a ceiling structure and elevator that allows for easy disassembly and reassembly of the ceiling with minimal manpower.
[0004] Firstly, this application proposes a suspended ceiling structure.
[0005] The suspended ceiling structure according to an embodiment of this application is applied to an elevator, the elevator including a car, and the suspended ceiling structure of the embodiment includes:
[0006] The system includes: a ceiling frame with a hollowed-out area; several rotating connecting mechanisms, one end of which is connected to a first side of the ceiling frame and the other end to the top of the car, the rotating connecting mechanisms being used to rotate the ceiling frame up and down relative to the top of the car; several locking mechanisms, one end of which is connected to a second side of the ceiling frame and the other end to the top of the car, the locking mechanisms being used to lock the ceiling frame in a fixed position on the top of the car; and a lighting assembly including a light source module and a light-transmitting plate, the light source module being disposed on the top of the car and the light-transmitting plate being disposed on the ceiling frame and covering the hollowed-out area.
[0007] The ceiling structure according to the embodiments of this application has at least the following beneficial effects: By centrally arranging the rotating connection mechanism on the first side of the ceiling frame, a single-sided rotating fulcrum is formed. Operators only need to release the locking mechanism on the second side to achieve downward rotation of the ceiling frame around the rotating axis. Compared to the traditional four-corner bolt disassembly method, the ceiling can be rotated and unfolded within a 90° range without lifting it, thus allowing access to the equipment on the top of the car, significantly reducing labor and time costs. In the closed state, the locking mechanism mechanically engages and fixes the second side of the ceiling frame, preventing accidental ceiling rotation. During maintenance, the rotating shaft assembly in the rotating connection mechanism maintains a physical connection with the top of the car throughout the rotation process, avoiding the risk of the ceiling falling due to complete detachment. Furthermore, during installation, the ceiling structure of this embodiment only requires pushing one side of the ceiling frame upwards to engage the locking mechanism, thus completing the installation and securing of the ceiling, eliminating the complex operation of lifting the entire ceiling for screw hole alignment.
[0008] According to some embodiments of this application, the rotary connection mechanism includes:
[0009] A first connecting bracket, one end of which is connected to the first side of the ceiling frame;
[0010] The second connecting bracket has one end connected to the position on the top of the car corresponding to the first connecting bracket;
[0011] The other end of the first connecting bracket is movably connected to the other end of the second connecting bracket via a pivot to enable the ceiling frame to flip.
[0012] According to some embodiments of this application, the locking mechanism includes a hook and a mounting element;
[0013] The hook is installed on the ceiling frame, and the mounting bracket is installed on the top of the car.
[0014] The hook engages with the mounting bracket to lock the position of the ceiling frame.
[0015] According to some embodiments of this application, the locking mechanism includes a hook and a mounting element;
[0016] The hook is provided on the top of the car, and the mounting bracket is provided on the ceiling frame;
[0017] The hook engages with the mounting bracket to lock the position of the ceiling frame.
[0018] According to some embodiments of this application, the light source module includes:
[0019] A light panel, wherein the light panel is disposed on the top of the car;
[0020] Several light strips are provided on the light panel and are connected to the light panel by snap-fit.
[0021] According to some embodiments of this application, the ceiling frame includes two horizontal frames and two vertical frames, with the two ends of the vertical frames respectively connected to the two ends of the two horizontal frames to form a frame structure with the hollowed-out area.
[0022] According to some embodiments of this application, the vertical frame and the horizontal frame are provided with protrusions and light-transmitting plate fixing members on the side facing the hollow area. The protrusions and the light-transmitting plate fixing members are used to fix the position of the light-transmitting plate in the ceiling frame.
[0023] According to some embodiments of this application, the ceiling structure further includes a plurality of air guide plates, which are connected to the ceiling frame and are inclined toward the edge of the ceiling frame. The air guide plates are used to guide the airflow of the fan at the top of the car into the car.
[0024] According to some embodiments of this application, the locking mechanism further includes an anti-detachment bolt, which is disposed on the top of the car. When the ceiling frame is locked to the top of the car, one end of the anti-detachment bolt abuts against the hook tip of the hook to prevent the locking mechanism from loosening.
[0025] Secondly, this application also provides an elevator, including the ceiling structure described in any embodiment of the first aspect of this application.
[0026] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0040] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0041] In a first aspect, this application provides a suspended ceiling structure, including: a suspended ceiling frame 100, a plurality of rotating connection mechanisms 200, a plurality of locking mechanisms 300, and lighting components. For example... Figure 1 and Figure 2As shown, the ceiling frame 100 has a hollow area for mounting and supporting the light-transmitting panel 420, allowing light from the lighting components to pass through the ceiling frame 100 and illuminate the car interior. The ceiling frame 100 can be made of metal profiles (such as aluminum alloy or stainless steel) or other materials with sufficient strength and stability. The ceiling frame 100 is rotatably connected to the car top via several rotating connection mechanisms 200. For example, each rotating connection mechanism 200 includes a first connecting bracket 210 and a second connecting bracket 220. The first connecting bracket 210 is fixed or hinged to one side (e.g., the rear side) of the ceiling frame 100, and the second connecting bracket 220 is fixed to the car top. By providing a pivot 230 or a pin, the first connecting bracket 210 and the second connecting bracket 220 are movably hinged, thereby enabling the ceiling frame 100 to rotate up and down around the pivot 230. The other side of the ceiling frame 100 (usually the front side opposite the rotating connection mechanism 200) is connected to the top of the car via several locking mechanisms 300. Specifically, this may include the engagement of hooks 320 and hangers 310, or the mutual engagement of hooks 320 and hangers 310. For different installation requirements, hooks 320 can be set on the ceiling frame 100 and hangers 310 can be set on the top of the car, or vice versa. The hooks 320 and hangers 310 lock the ceiling frame 100 in a fixed position through hooking or interlocking, preventing the ceiling frame 100 from accidentally flipping or loosening. In actual installation, when the ceiling needs to be rotated, maintenance personnel only need to loosen or remove the locking mechanism 300, and the ceiling frame 100 can rotate downwards around the rotating connection mechanism 200. During installation or use, the ceiling frame 100 simply needs to be rotated upwards to reset, and then fastened or locked using the locking mechanism 300. This simple operation effectively prevents the ceiling from falling. The lighting components include a light source module 410 and a light-transmitting panel 420. The light source module 410 is preferably located on the top of the car, but it can also be directly mounted on the ceiling frame 100, allowing it to rotate downwards synchronously with the ceiling frame 100. The light-transmitting panel 420 covers the open area of the ceiling frame 100. The light-transmitting panel 420 can be made of acrylic or other highly transparent and durable materials. Similarly, for ease of assembly and disassembly, a disassembly structure can be configured at each edge of the light-transmitting panel 420. For example, pressure plates or retaining components can be installed at corresponding positions on the ceiling frame 100 to press or lock the light-transmitting panel 420 in place. When needed, the light-transmitting panel 420 can be easily replaced or cleaned by loosening the fixing components.
[0042] In normal operation, the ceiling frame 100 is securely fixed to the top of the car via the rotating connection mechanism 200 and the locking mechanism 300; the lighting components provide a good lighting environment for the car through the light-transmitting panel 420. When maintenance is required, the locking mechanism 300 is first released, allowing the ceiling frame 100 to rotate around the pivot 230 at the rotating connection mechanism 200. Maintenance personnel only need to support one side of the ceiling frame 100 inside the car and slowly rotate it downwards, exposing part or all of the space originally covered by the ceiling, facilitating the replacement of the light source module 410 or maintenance of the equipment on the top of the car; during installation, the ceiling frame 100 is rotated back to its original position, and the hooks 320, the mounting brackets 310, and other locking mechanisms 300 are fastened or tightened to prevent the ceiling frame 100 from falling, thus completing the reset operation. Compared to the traditional four-corner fixed ceiling structure, this embodiment allows the ceiling to be rotated without multiple people disassembling and assembling parts, significantly shortening maintenance time, reducing labor costs, and improving elevator safety and maintenance efficiency.
[0043] Understandable, such as Figure 3 As shown, the rotating connection mechanism 200 includes two main components: a first connecting bracket 210 and a second connecting bracket 220. One end of the first connecting bracket 210 is hinged or hinged to one side of the ceiling frame 100 (e.g., the rear side of the ceiling), and the second connecting bracket 220 is correspondingly fixed at a corresponding position on the top of the car. Specifically, the first connecting bracket 210 can be connected to the ceiling frame 100 by bolts or riveting; the second connecting bracket 220 can also be fixed to the top of the car in the same or similar way. A pivot 230 (or pin) is provided between the first connecting bracket 210 and the second connecting bracket 220 to achieve their movable hinge, allowing the ceiling frame 100 to rotate up and down around the pivot 230. For example, the pivot 230 can pass through the aligned holes of the first connecting bracket 210 and the second connecting bracket 220 with a certain gap. Preferably, to ensure smooth rotation and facilitate the subsequent engagement of the locking mechanism 300, the assembly between the rotating shaft 230 and the bracket does not require a perfectly tight fit; a certain amount of sway can be reserved. This sway can be achieved through the assembly gap between the rotating shaft 230 and the bracket hole, or by using a moderately elastic material for the first connecting bracket 210 and / or the second connecting bracket 220. When it is necessary to rotate the ceiling frame 100 back to its original position, maintenance personnel can slightly twist or gently pry the ceiling frame 100 up and down, left and right, or back and forth to allow the locking mechanism 300 to be easily engaged or disengaged, thus greatly simplifying the operation.
[0044] The locking mechanism 300 provides effective fixing and unlocking functions for the ceiling frame 100 and the other side of the car top, for example, in the form of a structure in which a hook 320 and a mounting bracket 310 cooperate. In practical applications, the hook can be set on the ceiling frame, and the mounting bracket can be set on the car top. When the ceiling frame is flipped back to the top, the hook 320 will automatically, or after a slight twist, engage with the mounting bracket on the car top, thereby reliably fixing the ceiling in the predetermined position; as shown Figure 4 As shown, the hook 320 can also be installed on the top of the car, while the corresponding mounting bracket 310 can be installed on the ceiling frame 100. Both are locked together by interlocking. The choice of arrangement can be adjusted according to design preferences or on-site installation requirements.
[0045] When the ceiling frame 100 needs to be flipped downwards, the operator first needs to disengage or loosen the engagement structure between the hook 320 and the mounting bracket 310, for example, by loosening the bolts or gently lifting or pressing down the hook 320 to disengage it from the mounting bracket 310. Then, the ceiling frame 100 can be flipped downwards by rotating the connecting mechanism 200. At this time, the ceiling frame 100 is only connected to the top of the car by the pivot 230 and will not completely detach. When the maintenance or replacement of the light fixtures is completed and the ceiling frame 100 needs to be flipped back to its original position, the maintenance personnel only need to reverse the operation, slowly flipping the ceiling frame 100 upwards while slightly swinging it left and right, back and forth, or up and down, so that the hook 320 can be accurately inserted into or fall into the mounting bracket 310. Once the hook is in place, the ceiling frame 100 and the top of the car are stably locked again, thus ensuring that there is no risk of accidental flipping or falling off during use.
[0046] Furthermore, such as Figure 4 As shown, in order to further prevent the locking mechanism 300 from loosening under vibration or external force, limit bolts or other forms of anti-detachment structures can be added to key positions of the hook 320 or the hanger 310 to tightly abut and fix the hook tip of the hook 320 or the edge of the hanger 310, thereby achieving higher safety.
[0047] Understandable, such as Figure 1 and Figure 2As shown, the ceiling frame 100 can be composed of two longitudinal frames 120 and two transverse frames 110. The four frames are joined at their ends and fixed by bolts or rivets to form an overall frame structure around the hollow area. This frame supports the light-transmitting panel 420, the air guide plate 500, and related components such as lighting fixtures, and can be flipped and securely locked with the cooperation of the rotating connection mechanism 200 and the locking mechanism 300. The materials of the transverse frames 110 and longitudinal frames 120 are preferably aluminum alloy, stainless steel, or other lightweight and sufficiently strong metal materials, which ensures the stability of the overall frame structure and does not increase the load or occupy too much space in the elevator car. Matching screw holes or pre-embedded nuts are reserved at the joints of the longitudinal and transverse frames 110 to facilitate later assembly or disassembly. If necessary, a small amount of spot welding can be performed at the joints to further enhance the connection strength or stability, but screw connections can be used in general to simplify the manufacturing process. The specifications of the hollow area can be planned according to the interior space of the elevator and lighting requirements to ensure the effective light-transmitting area of the light-transmitting panel 420.
[0048] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, on the side of the ceiling frame 100 facing the openwork area, both the longitudinal frame 120 and the transverse frame 110 are provided with protrusions and retaining members for supporting and fixing the light-transmitting panel 420. The protrusions typically have an inwardly extending boss, guide rail, or bend on the inner edge of both the longitudinal frame 120 and the transverse frame 110, forming a support platform on which the light-transmitting panel 420 can be stably placed. To prevent the light-transmitting panel 420 from shifting or falling off due to vibration or external forces during elevator operation, pressure plates, clips 413, or other forms of fasteners can be installed on the protrusions or adjacent positions to clamp or limit the light-transmitting panel 420 in conjunction with the protrusions. When it is necessary to replace or clean the light-transmitting panel 420, simply loosen or remove the fastening element (such as a screw or clip 413) of the retaining member, and gently remove the light-transmitting panel 420, greatly facilitating maintenance operations.
[0049] In some embodiments, the light source module 410 mainly consists of a lamp panel 411 and several lamp strips 412 (or LED light strips). Figure 5 and Figure 6 As shown, the light panel 411 is mounted on the top of the car and fixed by bolts or clips 413; the light strips 412 are arranged on the surface or internal structure of the light panel 411, so that its light can be evenly irradiated into the car through the light-transmitting plate 420 on the ceiling frame 100. Compared with the traditional LED light strips 412 fixed by bolts, the light strips 412 and the light panel 411 in this embodiment adopt a clip assembly method 413, which greatly simplifies the assembly and disassembly work. When replacing, the light strips 412 can be removed and installed simply by gently prying open or pressing the clips 413, without the need for cumbersome hole alignment or tightening operations.
[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the ceiling structure is also equipped with several air guide plates 500. These air guide plates 500 are connected to the ceiling frame 100 and tilted towards the edge of the frame to guide the airflow generated by the ceiling fan into the elevator car, enhancing air circulation and comfort. The air guide plates 500 are typically fixed to the left, right, front, or rear sides of the ceiling frame 100, at a certain angle towards the inside of the car. The specific tilt angle can be set based on the location of the ceiling fan and the airflow speed to achieve the best airflow guiding effect.
[0051] Secondly, this application also provides an elevator, including a ceiling structure according to any embodiment of the first aspect of this application. The function and principle of the elevator in this embodiment are based on the above-described ceiling structure. Therefore, the elevator of this application has the same beneficial effects as the above-described ceiling structure, and will not be repeated here for the sake of brevity.
[0052] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
