[0039] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0040] As Figures 1-9 shown, this embodiment provides a magnetic car wall, which includes adjacent first car wall unit 100 and second car wall unit 200; the first car wall unit 100 and the second car wall unit 200 can be on the same plane or have a certain included angle with each other. A first electromagnet 110 is provided on the first car wall unit 100, and a magnetic part 210 is provided on the second car wall unit 200. The first electromagnet 110 is connected to an external power supply device through an electric wire. The first electromagnet 110 can generate an adsorption force on the magnetic part 210 when it is in the energized state. When installing the first car wall unit 100 and the second car wall unit 200, first place the first car wall unit 100 and the second car wall unit 200 adjacent to each other, so that the position of the first electromagnet 110 on the first car wall unit 100 can correspond to the position of the magnetic part 210 on the second car wall unit 200. Then turn on the external power supply device to supply power to the first electromagnet 110 through the external power supply device, so that the first electromagnet 110 can adsorb the magnetic part 210 when it is in the energized state, thereby realizing the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0041] It can be understood that the fixed connection between the first car wall unit 100 and the second car wall unit 200 is realized through the adsorption between the first electromagnet 110 and the magnetic part 210. During the installation process, the installer only needs to place the first car wall unit 100 and the second car wall unit 200 adjacent to each other. The installer does not need to enter the elevator shaft for installation operations, which is convenient for the installer to install and improves the safety of the installer's work.

[0042] It should be further noted that the adsorption force between the first electromagnet 110 and the magnetic component 210 can be adjusted by the magnitude of the supply current. As the current supplied to the first electromagnet 110 increases, the adsorption force that the first electromagnet 110 can generate on the magnetic component 210 also increases. Therefore, the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200 can be better ensured, improving the safety of the entire elevator car during operation. At the same time, as the current supplied to the first electromagnet 110 decreases, the adsorption force that the first electromagnet 110 can generate on the magnetic component 210 also decreases. Therefore, it is more convenient to disassemble the first car wall unit 100 and the second car wall unit 200, facilitating use.

[0043] In some embodiments, the magnetic component 210 can be a second electromagnet, or the magnetic component 210 can be made of a material with magnetic conductivity, as long as it can be adsorbed by the first electromagnet 110 in the energized state, and there is no special limitation on this.

[0044] It should be noted that the materials with magnetic conductivity include iron, nickel, cobalt, steel, magnets, etc. Therefore, the magnetic component 210 can be made of the above materials or objects or products made of these materials.

[0045] Particularly, when the magnetic component 210 is a second electromagnet, the second electromagnet is also connected to an external power supply device through a wire. During the installation process, after the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, the first electromagnet 110 and the second electromagnet are simultaneously powered by the external power supply device, so that both the first electromagnet 110 and the second electromagnet generate magnetic forces, and then the first electromagnet 110 and the second electromagnet can adsorb each other, thereby realizing the fixed connection between the first car wall unit 100 and the second car wall unit 200. And because both the first electromagnet 110 and the second electromagnet can generate a certain magnetic force, the adsorption effect between them can be more stable, preferably improving the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200, and further improving the safety of the entire elevator car during operation.

[0046] In some embodiments, a first connecting plate 120 is provided on the side of the first car wall unit 100 facing the inner wall of the elevator shaft, and a second connecting plate 220 is provided on the side of the second car wall unit 200 facing the inner wall of the elevator shaft; the first electromagnet 110 is installed on the first connecting plate 120, and the magnetic component 210 is installed on the second connecting plate 220. During the installation process, the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other. At this time, the first connecting plate 120 and the second connecting plate 220 can be in a parallel state with each other, and both the first electromagnet 110 and the magnetic component 210 are located between the first connecting plate 120 and the second connecting plate 220.

[0047] Since the first connecting plate 120 and the second connecting plate 220 remain parallel to each other in the installed state, the first electromagnet 110 provided on the first connecting plate 120 and the magnetic member 210 provided on the second connecting plate 220 can maintain a relatively positioned state. Furthermore, the adsorption force between the first electromagnet 110 and the magnetic member 210 can be perpendicular to the first connecting plate 120 and the second connecting plate 220, maintaining the positive adsorption of the first electromagnet 110 and the magnetic member 210, avoiding the skew of the adsorption force, and thus can preferably improve the stability of the adsorption between the first electromagnet 110 and the magnetic member 210, improve the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200, and improve the safety of the entire elevator car operation.

[0048] Combined with Figures 10-12 As shown, in some embodiments, when the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, at this time, the first electromagnet 110 connected to the first connecting plate 120 can have the freedom to move in the direction towards the magnetic member 210, that is, the first electromagnet 110 can move between the first connecting plate 120 and the second connecting plate 220.

[0049] After the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, the first electromagnet 110 is powered by an external power supply device, and the first electromagnet 110 generates a magnetic force. At this time, the first electromagnet 110 will generate an adsorption force on the magnetic member 210. Under the action of the adsorption force, the first electromagnet 110 will actively move in the direction towards the magnetic member 210 until the first electromagnet 110 directly contacts the magnetic member 210, thereby completing the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0050] It can be understood that the direct contact adsorption between the first electromagnet 110 and the magnetic member 210 has higher stability, which can improve the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200. By giving the first electromagnet 110 a certain degree of freedom of movement, it can preferably avoid errors in production or installation, resulting in a gap between the first electromagnet 110 and the magnetic member 210 when the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other.

[0051] Combined with Figures 10-12 As shown, in some embodiments, a first positioning hole 121 and a first half-thread bolt 122 are provided on the first connecting plate 120, and a first threaded hole 111 is provided on the first electromagnet 110. The threaded section of the first half-thread bolt 122 passes through the first positioning hole 121 and extends into the first threaded hole 111, thereby realizing the connection and installation of the first electromagnet 110 on the first connecting plate 120.

[0052] It can be understood that the threaded section of the first half-threaded bolt 122 extends into the first threaded hole 111 of the first electromagnet 110, while the unthreaded section of the first half-threaded bolt 122 passes through the first positioning hole 121, enabling the first half-threaded bolt 122 to move along the axial direction of the first positioning hole 121 in the first positioning hole 121 through the unthreaded section, and further enabling the first electromagnet 110 to be movable between the first connecting plate 120 and the second connecting plate 220.

[0053] After the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, the first electromagnet 110 is powered by an external power supply device, so that an adsorption force is generated between the first electromagnet 110 and the magnetic member 210. Under the action of the adsorption force, the first electromagnet 110 has a tendency to move in the direction of the magnetic member 210. At this time, the first half-threaded bolt 122 moves along the axial direction of the first positioning hole 121 in the first positioning hole 121 through the unthreaded section, thereby realizing the movement of the first electromagnet 110 in the direction of the magnetic member 210, and further realizing the direct-contact adsorption between the first electromagnet 110 and the magnetic member 210, which can preferably improve the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0054] Combined Figures 11-12 As shown, in some embodiments, the first electromagnet 110 includes a connecting portion 112 and a movable portion 113. Among them, one end of the connecting portion 112 is bolted to the first connecting plate 120, and an installation groove 112a is provided at the other end of the connecting portion 112. One end of the movable portion 113 is movably connected to the installation groove 112a through a spring or a clamping block.

[0055] After the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, the first electromagnet 110 is powered by an external power supply device, so that an adsorption force is generated between the first electromagnet 110 and the magnetic member 210. Under the action of the adsorption force, the movable portion 113 has a tendency to move in the direction of the magnetic member 210. Therefore, the movable portion 113 can move in the direction of the magnetic member 210 by stretching the spring or by moving the clamping block in the installation groove 112a, and further enabling the first electromagnet 110 to directly contact the magnetic member 210 through the movable portion 113 and adsorb with the magnetic member 210, which can preferably improve the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0056] Furthermore, since the first electromagnet 110 directly contacts and adsorbs the magnetic member 210 through the movable portion 113, it is possible to set that when the external power supply device supplies power to the first electromagnet 110, only the movable portion 113 generates magnetic force, while the connecting portion 112 only serves to connect the first electromagnet 110 to the first connecting plate 120.

[0057] Furthermore, the first threaded hole 111 can be provided on the connecting portion 112, and the connecting portion 112 is installed on the first connecting plate 120 through the first half-thread bolt 122, so that both the connecting portion 112 and the movable portion 113 can have a certain degree of freedom to move in the direction towards the magnetic member 210, thereby enabling better direct contact adsorption between the first electromagnet 110 and the magnetic member 210, and further improving the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0058] Combined with Figures 13-15 As shown, in some embodiments, when the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, at this time, the magnetic member 210 connected to the second connecting plate 220 can have a degree of freedom to move in the direction towards the first electromagnet 110, that is, the magnetic member 210 can move between the first connecting plate 120 and the second connecting plate 220.

[0059] After the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, the external power supply device supplies power to the first electromagnet 110, and the first electromagnet 110 generates magnetic force. At this time, the first electromagnet 110 will generate an adsorption force on the magnetic member 210. Under the action of the adsorption force, the magnetic member 210 will actively move in the direction towards the first electromagnet 110 until the magnetic member 210 directly contacts the first electromagnet 110, thereby completing the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0060] It can be understood that by giving the magnetic member 210 a certain degree of freedom of movement, it is possible to better avoid errors in production or installation, resulting in a gap between the first electromagnet 110 and the magnetic member 210 when the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other. Through the movement of the magnetic member 210, it is possible to better achieve direct contact between the first electromagnet 110 and the magnetic member 210, making the adsorption between the first electromagnet 110 and the magnetic member 210 more stable, and better improving the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0061] Combined with Figures 13-15As shown, in some embodiments, a second positioning hole 221 and a second half-threaded bolt 222 are provided on the second connecting plate 220, and a second threaded hole 211 is provided on the magnetic attraction member 210. The threaded section of the second half-threaded bolt 222 passes through the second positioning hole 221 and extends into the second threaded hole 211, thereby realizing the connection and installation of the magnetic attraction member 210 on the second connecting plate 220.

[0062] It can be understood that the threaded section of the second half-threaded bolt 222 extends into the second threaded hole 211 of the magnetic attraction member 210, while the unthreaded section of the second half-threaded bolt 222 passes through the second positioning hole 221, enabling the second half-threaded bolt 222 to move along the axial direction of the second positioning hole 221 in the second positioning hole 221, and further enabling the magnetic attraction member 210 to be movable between the first connecting plate 120 and the second connecting plate 220.

[0063] After the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, an external power supply device supplies power to the first electromagnet 110, causing an adsorption force to be generated between the first electromagnet 110 and the magnetic attraction member 210. Under the action of the adsorption force, the magnetic attraction member 210 has a tendency to move in the direction towards the first electromagnet 110. At this time, the second half-threaded bolt 222 moves along the axial direction of the second positioning hole 221 in the second positioning hole 221 through its unthreaded section, thereby realizing the movement of the magnetic attraction member 210 in the direction towards the first electromagnet 110, and further realizing the direct contact adsorption between the first electromagnet 110 and the magnetic attraction member 210, which can preferably improve the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0064] Combined Figures 14-15 As shown, in some embodiments, the magnetic attraction member 210 includes a connection seat 212 and a movable block 213. One end of the connection seat 212 is connected to the second connecting plate 220 by a bolt, and a movable groove 212a is provided at the other end of the connection seat 212. One end of the movable block 213 is movably connected to the movable groove 212a by a spring or a clamping block.

[0065] After the first car wall unit 100 and the second car wall unit 200 are placed adjacent to each other, an external power supply device powers the first electromagnet 110, so that an adsorption force is generated between the first electromagnet 110 and the magnetic part 210. Under the action of the adsorption force, the movable block 213 can have a tendency to move in the direction towards the first electromagnet 110. Therefore, the movable block 213 can move in the direction towards the first electromagnet 110 by stretching the spring or by the movement of the clamping block in the movable groove 212a. Furthermore, the magnetic part 210 can directly contact the first electromagnet 110 through the movable block 213 and be adsorbed to the first electromagnet 110, which can preferably improve the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0066] Furthermore, the second threaded hole 211 can be provided on the connecting seat 212, and the connecting seat 212 is installed on the second connecting plate 220 through the second half-threaded bolt 222, so that both the connecting seat 212 and the movable block 213 can have a certain degree of freedom to move in the direction towards the first electromagnet 110, thus preferably realizing the direct-contact adsorption between the first electromagnet 110 and the magnetic part 210, and further improving the stability of the fixed connection between the first car wall unit 100 and the second car wall unit 200.

[0067] In some embodiments, the first connecting plate 120 and the second connecting plate 220 are connected by fastening bolts.

[0068] It can be understood that after the first connecting plate 120 and the second connecting plate 220 are fixedly connected by the first electromagnet 110 and the magnetic part 210, and then connected by the fastening bolts, the stability of the connection between the first connecting plate 120 and the second connecting plate 220 can be further improved. Of course, the fastening bolts only play an auxiliary role in the connection between the first connecting plate 120 and the second connecting plate 220. During specific installation, the fastening bolts can be left untightened, with lower installation requirements and facilitating the installation operation of the installers.

[0069] Particularly, connecting the first connecting plate 120 and the second connecting plate 220 by the fastening bolts can preferably avoid the instability of the elevator car when the first electromagnet 110 and / or the magnetic part 210 fails, and can prevent the first car wall unit 100 and / or the second car wall unit 200 from tipping towards the inside or outside of the elevator car, preferably improving the safety.

[0070] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
