Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically a modular elevator car. Background Technology

[0002] In the car structure of home elevators, the connections between the various car walls are usually fixed with screws. Due to the limited space in the car, the connection process between the various car walls is usually cumbersome and complicated, making installation difficult. It is difficult to find fixed tools on the construction site to assist in the installation, which will cause great installation errors. The accumulation of errors during assembly will seriously affect the dimensional accuracy of the product. Furthermore, on-site installation is not easy to manage, which can easily lead to problems such as missing or incorrect installation of parts, affecting product quality and directly impacting the overall aesthetics of the car.

[0003] Chinese patent CN210944434U discloses a modular aluminum alloy car, including a pre-assembled rear wall assembly and two side wall assemblies. The rear wall assembly and the two side wall assemblies are assembled with mortise and tenon joints to form a frame structure with one open side. Front wall assemblies are respectively provided on both sides of the open end of the frame structure. The upper ends of the two front wall assemblies are connected to door lintels, and the two ends of the door lintels are respectively connected to the two side wall assemblies. Before installation, each car wall is pre-assembled into a whole module. During final assembly, the modules are directly assembled into a complete car. The car walls are fixed together by mortise and tenon joints, eliminating the need for fastening screws. This saves on the cost of connectors, saves labor, and makes the installation process simpler, more convenient, and streamlined.

[0004] While the aforementioned patented structures address the issue of convenient installation, certain shortcomings remain. Different users have varying requirements for the material of the car wall panels. For example, changing the wall material in the aforementioned prior art car structure requires disassembling the entire car frame, which is inconvenient and hinders modular processing and production. Furthermore, when the existing patented mid-range car walls are made of glass, the glass is prone to chipping during transportation and installation, resulting in visible chipped corners at certain angles inside the car after installation, affecting aesthetics and user experience. Summary of the Invention

[0005] The problem solved by this invention is to overcome at least one defect in the prior art by providing a modular elevator car, in which each car wall is set as an independent modular structure. When changing the car wall material, only the corresponding car wall module needs to be disassembled and replaced, without disassembling the car frame structure. It has a high degree of modularity and is convenient to disassemble and replace.

[0006] To address the above problems, the present invention provides a modular elevator car, comprising a car frame, a rear wall assembly, two front side wall assemblies, two side panels, and two rear side wall assemblies.

[0007] The two rear columns of the car frame form a rear wall mounting part with the upper and lower rear crossbars, and the upper end of the lower rear crossbar is provided with a first slot. The lower end of the rear wall assembly is inserted into the first slot, and the upper end is detachably connected to the upper rear crossbar.

[0008] The upper and lower crossbars on both sides of the car frame are respectively provided with first and second vertical bars at intervals. Each first vertical bar is detachably connected to the corresponding front pillar with a side front wall assembly, and each second vertical bar is detachably connected to the corresponding rear pillar with a side rear wall assembly. The side panel is disposed between the first and second vertical bars on the same side. The upper end of each lower crossbar on both sides of the car frame is provided with a second slot, and the lower ends of each side front wall assembly, side rear wall assembly, and side panel are respectively inserted into the corresponding slot. The upper ends of the side front wall assembly and the side rear wall assembly are detachably connected to the corresponding upper crossbar in the second slot on one side; the first vertical bar and the second vertical bar are both horizontally pullable and fitted with pressure strip assemblies on the side near the center of the car, and the two pressure strip assemblies on the same side are used to press and limit the front wall of the corresponding side plate respectively; the upper crossbars on the left, right and rear sides of the car frame facing the center of the car and the right-angle inner sides of the two rear columns facing the center of the car are detachably provided with first decorative pieces for respectively covering the outer edge of the corresponding wall assembly.

[0009] The modular elevator car of the present invention has the following advantages compared with the prior art:

[0010] The modular elevator car structure of this invention includes a complete and independent car frame, with a rear wall assembly installed on the rear side of the car. When the rear wall assembly needs to be replaced, the first decorative piece on the upper crossbar and rear column of the rear side of the car frame can be removed to replace the rear wall assembly, and the main structure of the car frame does not need to be disassembled during the disassembly and assembly process. Similarly, when replacing the wall assemblies on the left and right sides of the car frame, the main structure of the car frame does not need to be disassembled. More importantly, the structure of this invention has an operating box installed on the left or right side plate of the car frame. The connection structure of the side plate does not require any fasteners, saving costs and facilitating disassembly and assembly, so that the side wall module can be quickly replaced with different materials, such as replacing the glass module with a rock slab or leather panel. In addition, when the operating box needs maintenance, after removing the first decorative piece on the upper crossbar at the top, the pressure strip assemblies on both sides of the side plate can be pulled out horizontally to release the restriction on both sides of the side plate, and then the entire side plate can be pulled out of the slot without disassembling the main frame, especially the door operator, thus improving work efficiency.

[0011] Preferably, the outer walls of the first and second vertical supports near the center of the car are provided with positioning grooves extending along their length. The pressure strip assembly includes an elastic pressure strip and a first L-shaped decorative panel. The elastic pressure strip is housed within the positioning groove, and one side of the elastic pressure strip abuts against one side wall of the positioning groove. The vertical plate of the first L-shaped decorative panel extends into the positioning groove, and the vertical plate is pressed and limited between the other side of the elastic pressure strip and the other side wall of the positioning groove. The horizontal plate of the first L-shaped decorative panel is pressed against the front side wall of the side panel. In the above structure, the elastic deformation tension provided by the elastic pressure strip causes the first L-shaped decorative panel to be limited in the positioning groove, thereby achieving press-fitting and limiting of the two side walls of the side panel. The structure is simple and easy to operate.

[0012] In a further improvement, the pressure strip assembly also includes a second L-shaped decorative panel, and the vertical plate of the second L-shaped decorative panel is pressed and limited between the side of the elastic pressure strip away from the first L-shaped decorative panel and the side wall of the positioning groove; the horizontal plate of the second L-shaped decorative panel is pressed against the front side wall of the side front wall assembly or the side rear wall assembly. In the above improved structure, the horizontal plates of the two L-shaped decorative panels are respectively pressed against the front side wall of the side front wall assembly or the side rear wall assembly, realizing the pressing of the corresponding sides of the side front wall assembly or the side rear wall assembly and the decorative effect, thus improving the aesthetics.

[0013] In a further improvement, positioning slots are recessed on both sides of the positioning groove, and positioning ribs that mate with the positioning slots are correspondingly provided on the vertical plates of the first and second L-shaped decorative panels. In the above improved structure, the positioning slots and positioning ribs further enhance the stability of the first or second L-shaped decorative panel after it mates with the positioning groove, ensuring that the corresponding L-shaped decorative panel cannot be pulled out horizontally without the elastic pressure strip being removed.

[0014] Preferably, the elastic pressure strip is embedded with a light strip. In the above structure, the elastic pressure strip serves both as a limiting element for installation and as a source of light, enhancing the atmosphere of the car.

[0015] Further improvements include two front wall components. Door area pillars are respectively installed on both sides of the front of the car frame at the car door. These two door area pillars, along with the two front pillars and the upper and lower front crossbars, form two front wall mounting portions. Installation channels are provided on both sides of the front of the car frame for horizontally sliding the corresponding front wall components to the front wall mounting portions. Additionally, second decorative pieces are detachably installed on both sides of the front of the car frame to cover the outer ends of the front wall components. In this improved structure, horizontally movable and detachable front wall components are provided on the left and right sides of the front of the car frame, and second decorative pieces are also provided on the outer sides of the front components, further enhancing the modularity of the entire car structure and reducing the difficulty of replacing the decorative panels.

[0016] In a further improvement, a first sliding groove is provided at the lower end of the upper crossbar on the front side of the car frame, and a second sliding groove is provided at the upper end of the lower crossbars at both ends of the front side of the car frame. The upper and lower ends of the front wall assembly are slidably fitted into the first and second sliding grooves, respectively. The second decorative piece has an L-shaped structure, with its first right-angled edge pressed against the front end face of the outer side of the front wall assembly, and its second right-angled edge attached to the outer wall of the corresponding front pillar by self-tapping screws. In the above improved structure, the front wall assembly is directly slidably fitted into the corresponding sliding groove, resulting in a simple structure and convenient assembly and disassembly.

[0017] In a further improvement, the rear wall assembly, the front side wall assembly, the rear side wall assembly, and the front wall assembly all include a decorative panel and an aluminum alloy frame surrounding it. The top of the aluminum alloy frame of each of the rear wall assembly, the front side wall assembly, the rear side wall assembly, and the front wall assembly is connected to a horizontally arranged "Z"-shaped connector. The upper end of each "Z"-shaped connector is connected to a corresponding upper crossbar via fasteners. In this improved structure, each wall assembly has an aluminum alloy frame installed around the decorative panel, facilitating the connection between the wall assembly and the car frame. Furthermore, the corners of the decorative panel have protective structures, making it less prone to damage during handling and installation.

[0018] In a further improvement, the upper crossbars on the left, right, and rear sides of the car frame are each provided with at least one upward-facing slot extending along their length. The second decorative element on the left, right, and rear sides of the car frame is a crossbar cover, and the side of the crossbar cover away from the car center is provided with at least one downward-bent hook that engages with the slot. In this improved structure, the crossbar cover and the upper crossbar use a hook and slot fitting structure. During disassembly, simply pull the crossbar cover vertically upwards to disengage the hook from the slot, and then the entire crossbar cover can be removed directly, which is very convenient.

[0019] In a further improvement, the first decorative element at the right angle of the rear column includes a limiting strip and a decorative cover. The limiting strip includes two abutment plates that respectively abut against the vertically arranged side rear wall assembly and rear wall assembly. The two abutment plates are connected into an integral structure by a horizontal base plate. The horizontal base plate is connected to the rear column by self-tapping screws, and the decorative cover is snap-fitted between the two abutment plates.

[0036] like Figure 1-10As shown, the present invention provides a modular elevator car, including a car frame 1, a rear wall assembly 2, two front side wall assemblies 3, two side panels 4, two rear side wall assemblies 5, and two front wall assemblies 6; wherein the car frame 1 is a rectangular frame, which is assembled from two front columns 14, two rear columns 11, four upper crossbars 8, and five lower crossbars 9; and a car door is provided on the front side wall of the car frame 1, with door area columns 7 on both sides of the car door, and a door area beam connected to the top of the two door area columns 7. The door area beam is connected to the upper crossbars 8 on the front side. In the car structure, the upper crossbar located on the side of the car door is also called the door lintel, and its width is wider than the other upper crossbars; in addition, since a welcome step is required at the bottom of the door area, two lower crossbars 9 are provided at the front end of the car frame 1, and the two lower crossbars 9 on the front side are respectively located between the two door area columns 7 and the two front columns 14.

[0037] In addition, the two door area pillars 7 form two front wall mounting parts with the two front pillars 14, the front upper crossbar 8, and the lower crossbar 9 respectively. The front sides of the car frame 1 are respectively provided with mounting channels for the corresponding front wall components 6 to be horizontally slidably installed to the front wall mounting parts, and the front sides of the car frame 1 are respectively provided with second decorative parts for covering the outer end of the front wall components 6.

[0038] like Figure 8 As shown, more specifically, in the above structure, a first sliding groove 26 is provided at the lower end of the upper crossbar 8 on the front side of the car frame 1. Correspondingly, a second sliding groove 27 is provided at the upper end of the lower crossbars 9 at both ends of the front side of the car frame 1. The upper and lower ends of the two front wall components 6 are slidably fitted into the corresponding first sliding groove 26 and second sliding groove 27, respectively. In addition, the second decorative piece is an L-shaped structure, and the first right-angled edge of the second decorative piece is pressed against the front end face of the outer side of the front wall component 6. The second right-angled edge of the second decorative piece is attached to the outer side wall of the corresponding front pillar 14 by self-tapping screws, thereby achieving horizontal limiting of the front wall component 6. In this structure, in order to further improve the stability of the front wall component 6 after installation, elastic rubber strips 37 are provided on both the front and rear sides near the end of the second decorative piece. The elastic rubber strips 37 on the front and rear sides of the front wall component 6 are respectively abutted against the corresponding front pillar 14 and the right-angled edge of the second decorative piece, such as... Figure 9As shown. Additionally, a recessed positioning groove 34 is provided on the left side wall of the left front pillar 14 or the right side wall of the right front pillar 14. The following explanation uses the left front pillar 14 as an example: A forward-extending positioning stop 35 is provided at the rear opening of the positioning groove 34. Correspondingly, a backward-bent positioning hook 36 is provided on one of the right-angled sides of the second decorative piece on the left side of the car frame 1. When the second decorative piece is installed on the left side of the front end of the car frame 1, the right-angled side abutting against the left side wall of the left front pillar 14, in addition to being connected to the left side wall of the front pillar 14 via self-tapping screws, is also engaged with the positioning stop 35 via the positioning hook 36, further improving the stability of the connection structure and preventing it from horizontally detaching from the front pillar 14. The connection structure between the right front pillar 14 and the corresponding second decorative piece is the same as that on the left, and will not be described further.

[0039] like Figure 3 , 5 As shown, in this embodiment, a rear wall mounting portion is formed between the two rear columns 11 of the car frame 1 and the upper and lower crossbars 8 and 9 on the rear side. A first slot is provided on the upper end of the lower crossbar 9 on the rear side. The lower end of the rear wall assembly 2 is inserted into the first slot, and the upper end is detachably connected to the upper crossbar 8 on the rear side. A first vertical bar 12 and a second vertical bar 13 are respectively provided between the upper and lower crossbars 9 on the left and right sides of the car frame 1. A side front wall assembly 3 is detachably provided between each first vertical bar 12 and the corresponding front column 14 on the same side. A side rear wall assembly 5 is detachably provided between each second vertical bar 13 and the corresponding rear column 11 on the same side. The side plate 4 is located between the first vertical bar 12 and the second vertical bar 13 on the same side. Similarly, a second slot is provided on the upper end of the lower crossbars 9 on the left and right sides of the car frame 1. Each side front wall assembly 3 and side rear wall assembly 5 are detachably provided between the two lower crossbars 11 and the upper and lower crossbars 8 and 9 on the rear side of the car frame 1. The lower ends of component 5 and side panel 4 are respectively inserted into the second slot on the corresponding side, and the upper ends of side front wall component 3 and side rear wall component 5 can be detachably connected to the corresponding upper crossbar 8. In the above structure, the rear wall component 2, side front wall component 3, side rear wall component 5 and front wall component 6 all include a decorative panel 21 and an aluminum alloy frame 22 surrounding it. The top of the aluminum alloy frame 22 of the rear wall component 2, side front wall component 3, side rear wall component 5 and front wall component 6 are all connected to a horizontally arranged "Z" type connector 23. The upper end of each "Z" type connector 23 is connected to the corresponding upper crossbar 8 by fasteners such as screws. When it is necessary to replace the decorative panel 21, it is only necessary to loosen the corresponding screw, release the limit between the aluminum alloy frame 22 and the upper crossbar 8, and then pull out the corresponding wall component from the first slot or the second slot, which is very convenient.

[0040] In the above structure, the four vertical supports on both sides of the car correspond to the four straight beams, serving a shielding function and improving the car's aesthetics. In other embodiments, if aesthetics are not a concern, the control box 32 can be located at the rear of the car, i.e., the rear end of the car frame 1 can be configured as a three-part structure, with the middle part, where the control box 32 is installed, being a metal plate, having transparent glass or decorative panels 21 on both sides.

[0041] like Figure 4 , 6 As shown, since the upper end of the side panel 4 is not connected to the upper crossbar 8, in order to ensure the stability of the side panel 4, vertically extending pressure strip assemblies are detachably installed on the side of the first vertical bar 12 and the second vertical bar 13 near the center of the car. The two pressure strip assemblies on the same side are used to press and limit the corresponding side panel 4 on both sides of the front wall. The lower end of the side panel 4 is limited by the slot, and the left and right sides are pressed and limited by the corresponding pressure strip assemblies, thereby realizing the horizontal limitation of the side panel 4 and preventing the side from tipping over. Of course, in the above structure, the "Z"-shaped connectors 23 are exposed for easy disassembly and assembly. Therefore, in order to improve the aesthetics, a crossbar cover plate 33 as the first decorative piece 10 is detachably installed on the side of each upper crossbar 8 near the center of the car. The lower end of the crossbar cover plate 33 covers the front side wall assembly 3, the rear side wall assembly 5 and the front wall of the upper end of the side panel 4 to cover the connection structure and the assembly gap.

[0042] like Figure 7 As shown, in the above structure, the detachable connection between the crossbar cover 33 and the upper crossbar 8 means that at least one slot 24 with an upward opening and extending along its length is provided on the side of the upper crossbar 8 near the center of the car frame 1 on the left or right side. At least one hook 25 that bends downward and engages with the slot 24 is provided on the side of the crossbar cover 33 away from the center of the car. In this embodiment, preferably, there are two slots 24 arranged parallel to each other vertically, and correspondingly two hooks 25, so that the crossbar cover 33 is connected to the side wall of the upper crossbar 8 near the center of the car by hanging, without the need for any fasteners, which is convenient for installation and improves the aesthetic appearance.

[0043] like Figure 10As shown, similarly, after the rear wall assembly 2 is installed, there are also fitting gaps between its left and right sides and the two rear columns 11. Therefore, first decorative parts 10 are detachably installed on the right-angled inner sides of the two rear columns 11 facing the center of the car. The left and right sides of the two first decorative parts 10 respectively cover the rear end of the corresponding side rear wall assembly 5 and the left and right ends of the rear wall assembly 2, thereby sealing the fitting gaps and improving the aesthetics. In this structure, the first decorative part 10 at the right angle of the rear column 11 includes a limiting pressure strip 28 and a decorative cover 29. The limiting pressure strip 28 includes two abutment plates 30 that are respectively attached to the vertically arranged side rear wall assembly 5 and rear wall assembly 2. The two abutment plates 30 are connected into an integral structure by a horizontal base plate 31. The horizontal base plate 31 is connected to the rear column 11 by self-tapping screws, and the decorative cover 29 is snapped between the two abutment plates 30.

[0044] like Figure 6 As shown, in this embodiment, the detachable connection structure of the pressure strip assembly specifically refers to: positioning grooves 15 extending along their length direction are provided on the outer wall of the first vertical bar 12 and the second vertical bar 13 on the side near the center of the car, and the two pressure strip assemblies can be pulled out horizontally and embedded in the corresponding positioning grooves 15.

[0045] The pressure strip assembly includes an elastic pressure strip 16 and a first L-shaped decorative panel 17. The elastic pressure strip 16 is housed in a positioning groove 15, and one side of the elastic pressure strip 16 abuts against one side wall of the positioning groove 15. The vertical plate of the first L-shaped decorative panel 17 extends into the positioning groove 15, and the vertical plate is pressed and limited between the other side of the elastic pressure strip 16 and the other side wall of the positioning groove 15. The horizontal plate of the first L-shaped decorative panel 17 is pressed against the front side wall of the side panel 4.

[0046] The pressure strip assembly may also include a second L-shaped decorative panel 18, which is symmetrically distributed with the first L-shaped decorative panel 17. The vertical plates of the two L-shaped decorative panels are inserted into the positioning grooves 15 and abut against the two side walls of the positioning grooves 15 respectively. The elastic pressure strip 16 is interference-fitted between the vertical plates of the two L-shaped decorative panels. The vertical plates of the two L-shaped decorative panels are fitted with the corresponding positioning grooves 15 by the left and right squeezing force of the elastic pressure strip 16. In addition, the horizontal plates of the two L-shaped decorative panels are pressed onto the front side wall of the front wall assembly 3 or the rear side wall assembly 5 respectively, so as to achieve the pressing of the corresponding side of the front wall assembly 3 or the rear side wall assembly 5 and the decorative effect, thereby improving the aesthetics.

[0047] To further improve the stability of the vertical plate of the first L-shaped decorative panel 17 or the second L-shaped decorative panel 18 after it is engaged with the positioning groove 15, and to prevent it from easily coming off horizontally outward, in this embodiment, at least one positioning slot 19 is recessed on both sides of the positioning groove 15, and positioning ribs 20 that cooperate with the positioning slots 19 are correspondingly provided on the vertical plates of the first L-shaped decorative panel 17 and the second L-shaped decorative panel 18. In this structure, the height of the positioning ribs 20 should not be too high. It needs to ensure that, during installation, before the elastic strip 16 is pressed in, the vertical plates of the two L-shaped decorative panels can be horizontally inserted into the positioning grooves 15 respectively. When the vertical plates of the two L-shaped decorative panels are inserted into the positioning grooves 15 respectively and each positioning rib 20 is fitted into the corresponding positioning slot 19, the elastic strip 16 is pressed in. During this process, the elastic strip 16 is deformed by squeezing both sides towards the middle. Through the expansion force, the two vertical plates are forced to abut against the side walls of the positioning grooves 15 for a limited position. When it is necessary to remove the side panel 4 for maintenance of the control box 32, it is only necessary to pull out the elastic strip 16 first, remove the first L-shaped decorative panel 17 on the side closest to the side panel 4, and then lift the side panel 4 from small to large a short distance to easily remove it, which is very convenient.

[0048] In the above structure, such as Figure 3 , 9 As shown, mounting slots are provided on the rear side of the two front columns 14 on the front side of the car frame 1. The front ends of the two side front wall components 3 are respectively inserted into the corresponding mounting slots, and the rear ends are covered and limited by the second L-shaped decorative plate 18.

[0049] In addition, in this embodiment, a light strip is embedded in the elastic pressure strip 16, so that the elastic pressure strip 16 can not only limit the installation, but also provide a light-emitting effect, thereby enhancing the atmosphere of the car.

[0050] In this embodiment, each wall component adopts a modular structure, that is, each decorative panel 21 is equipped with an aluminum alloy frame 22 on its outer periphery. This facilitates installation and prevents corner chipping when the decorative panel 21 is made of glass, as the corners are prone to breakage without the frame to protect them, resulting in an unsightly appearance after installation. With this modular structure, users can customize and change the material of the decorative panel 21, and when changing the decorative panel 21 on any side, it is not necessary to disassemble the original frame structure, making it quick and efficient.

[0051] After the car frame 1 is assembled, it does not need to be disassembled when replacing the wall components. Specifically, when it is necessary to replace the front wall component 6, simply remove the second decorative piece from the outside of the car, and then pull the entire front wall component 6 out horizontally. Then, push the front wall component 6 to be replaced back into the installation channel in the horizontal direction to the limit position, and finally reinstall the second decorative piece.

[0052] When the rear wall assembly 2 needs to be replaced, first remove the horizontal bar cover 33 horizontally upwards, then remove the first decorative piece 10 on the rear column 11 to expose the installation structure of the rear wall assembly 2. Then remove the "Z" shaped connector 23 to separate the rear wall assembly 2 from the upper horizontal bar 8. The entire rear wall assembly 2 can then be pulled out of the first slot from bottom to top. After the new rear wall assembly 2 is installed, reinstall the first decorative piece 10 and the horizontal bar cover 33.

[0053] When it is necessary to replace the side wall assembly or repair the control box 32, first remove the crossbar cover 33 on the corresponding crossbar, and then pull out the elastic strip 16. After the elastic strip 16 is removed, the two L-shaped decorative panels can move horizontally and be taken out from the positioning groove 15 for quick disassembly of the square side panel 4.
