Description

Technical Field

[0001] This invention belongs to the field of elevator technology, specifically a multi-dimensional buffer-based elevator car interior protection structure. Background Technology

[0002] As an indispensable vertical transportation tool in modern buildings, the comfort and safety of elevators are key indicators of their quality. The interior of the elevator car, as the space passengers directly interact with, is not only related to aesthetics but also plays a vital role in safety and comfort.

[0003] Currently, elevator car interior panels are generally made of metal, wood, or composite materials and are directly fixed to the car walls using rigid connectors. In the event of an accidental collision, such as a rigid impact with the guide rails or a sudden acceleration or deceleration during emergency braking, the enormous impact energy is directly transmitted to the interior panels through the rigid connections. At the same time, vibrations generated by the traction machine, guide rail friction, and wind noise during elevator startup, operation, and braking are transmitted to the interior panels through the car structure, causing them to radiate low-frequency humming and high-frequency friction noise. Traditional rigid installation methods cannot effectively block this structural sound transmission, resulting in high noise levels inside the car and seriously affecting the quietness and comfort of the ride. To address this, we propose an elevator car interior protection structure based on multi-dimensional buffering. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a multi-dimensional buffer-based elevator car interior protection structure, which effectively solves the above problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elevator car interior protection structure based on multi-dimensional buffering, comprising four sets of first splicing devices, two sets of second splicing plates, and eight sets of third splicing plates. Each first splicing device includes multiple sets of first splicing plates, and connecting grooves are provided on both the front and rear sides of each set of first splicing plates. A first hinge is provided in the connecting groove of the first splicing plate. Multiple sets of first connecting devices are connected between the second and third splicing plates. Multiple sets of screw blocks are provided between the first splicing devices and the third splicing plates. The bodies of the first splicing devices and the third splicing plates are provided with screw holes that match the screw blocks.

[0006] Preferably, the first splicing board includes a first wood board layer, a metal reinforcement layer connected to the rear side of the first wood board layer, a plurality of metal honeycomb aluminum layers connected to the rear side of the metal reinforcement layer, a damping gel disposed inside the metal honeycomb aluminum layers, a decorative layer connected to the front side of the first wood board layer, and a sponge pad layer connected to the rear side of the damping gel.

[0007] Preferably, the second splicing board includes a second wooden board layer, and multiple sets of hollow support columns are connected to the lower side of the second wooden board layer. A rubber pad layer is connected to the lower side of the hollow support columns, and a shear thickening liquid layer is disposed inside the multiple sets of hollow support columns.

[0008] Preferably, multiple sets of second splicing devices are provided between the upper and lower third splicing plates. The second splicing device includes a fourth splicing plate and a fifth splicing plate. The front side of the fourth splicing plate and the fifth splicing plate is provided with a groove, and a second hinge is provided in the groove of the fourth splicing plate and the fifth splicing plate.

[0009] Preferably, the first connecting device includes a first fixing tube and a second fixing tube. The outer side of the first fixing tube is connected to the second splicing plate, and the outer side of the second fixing tube is connected to the second splicing plate. Multiple sets of third fixing tubes are connected to the upper side of the second fixing tube. A spring is connected to the inner wall of the third fixing tube, and a locking block is connected to the side of the spring near the first fixing tube.

[0010] Preferably, the upper and lower side walls of the second fixed tube are connected to rotating rods, and multiple sets of steel wire ropes are connected to the outer side of the rotating rods. The side of the steel wire ropes away from the rotating rods is connected to the locking block.

[0011] Preferably, the front sides of the fourth and fifth splicing plates are provided with grooves, and a sixth splicing plate is placed in the grooves of the fourth and fifth splicing plates.

[0012] Preferably, a flap is connected to the upper side of the second splicing plate on the lower side.

[0013] Preferably, the upper and lower sides of the card block are connected to sliders, and the inner wall of the third fixing tube is provided with a groove that matches the slider of the card block.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By setting up a first splicing device, two sets of second splicing plates, eight sets of third splicing plates, and a first connecting device in conjunction with screw blocks, this device can be quickly assembled without on-site processing. The upper side of the front second splicing plate is movably connected with a flap. After the device is installed, it does not need to be fixed to the inner wall of the elevator car, so there is no need for a rigid connection with the elevator. This method improves the installation speed and efficiency of this device. By combining multiple protective materials in the first splicing plate, multiple energy dissipation from linear to nonlinear and from instantaneous to delayed can be achieved. At the same time, the first splicing plate reduces sound propagation while providing protection, improving the comfort of the elevator car during use. The decorative layer enhances the aesthetics of the device. By setting up a second splicing plate, the impact force on the elevator car can be reduced. The rubber pad layer reduces the impact force generated during the impact process, and the material itself reduces the noise while providing cushioning, thus improving the comfort of using the elevator car. By setting the fourth and fifth splicing plates, the two sets of second splicing plates are limited, and the upper second splicing plate is assisted in the installation work. By setting the sixth splicing plate, the first splicing device can be assisted in the support, and the first splicing device can also be fixed by tools such as pneumatic nails, thereby improving the stability of the device during long-term use. By setting up the first connecting device, the second and third splicing plates can be quickly connected, improving the installation speed and convenience of the device. By setting up steel wire ropes, rotating rods, and locking blocks, workers can easily disassemble the second and third splicing plates, improving the practicality of the device.

[0019] In order to solve the problems in the background art, please refer to the following: Figure 1-8A multi-dimensional buffer-based elevator car interior protection structure includes four sets of first splicing devices 100, two sets of second splicing plates 200, and eight sets of third splicing plates 300. Each first splicing device 100 includes multiple sets of first splicing plates 110, with connecting grooves on both the front and rear sides. First hinges 120 are installed within the connecting grooves of the first splicing plates 110. Multiple sets of first connecting devices 400 connect the second splicing plates 200 and the third splicing plates 300. Multiple sets of screw blocks 500 are installed between the first splicing devices 100 and the third splicing plates 300. The body of 300 has screw holes that match those of the screw block 500. Multiple sets of first splicing plates 110 can be folded during use via the first hinge 120, allowing the entire first splicing device 100 to be folded. This facilitates the entry of the first splicing device 100 into the elevator, as well as its movement and storage. During installation, a set of second splicing plates 200 is pre-installed on the lower side of the elevator. Then, four sets of third splicing plates 300 are pre-connected to the lower second splicing plates 200 via the first connecting device 400. Finally, the upper second splicing plates... The second splicing plate 200 and the other four sets of third splicing plates 300 are pre-assembled via the first connecting device 400. Then, the upper second splicing plate 200 and the four sets of third splicing plates 300 are placed on the upper side of the elevator box. At this point, the first splicing devices 100 on the left and right sides are quickly deployed to support the upper second splicing plate 200. Then, the first splicing devices 100 on the front and rear sides are deployed. After all four sets of first splicing devices 100 are deployed, the third splicing plates 300 and the first splicing devices 100 are pre-fixed via screw blocks 500. Subsequently, as needed... The device can be reinforced with an air gun, or, if necessary, not reinforced, thus completing the main installation. The device can be quickly assembled by using a first splicing device 100, two sets of second splicing plates 200, eight sets of third splicing plates 300, a first connecting device 400, and screw blocks 500, without requiring on-site processing. A flap 201 is movably connected to the upper side of the front second splicing plate 200.

[0020] The first splicing panel 110 includes a first wooden board layer 111, a metal reinforcing layer 112 fixedly connected to the rear side of the first wooden board layer 111, multiple sets of metal honeycomb aluminum layers 113 fixedly connected to the rear side of the metal reinforcing layer 112, damping gel 114 disposed inside the metal honeycomb aluminum layers 113, a decorative layer 115 fixedly connected to the front side of the first wooden board layer 111, and a sponge pad layer 116 fixedly connected to the rear side of the damping gel 114. During use, the first wooden board layer 111 provides the first layer of protection for the first splicing panel 110, and reduces impact force based on the material of the first wooden board layer 111. Furthermore, even if the surface of the first wooden board layer 111 is damaged, it will not easily scratch personnel. The metal reinforcing layer 112 reinforces the entire first splicing panel 110, providing a solid foundation for the first splicing panel 110. 10. Overall hardness is guaranteed. The metal honeycomb aluminum layer 113 absorbs and dissipates impact energy through its plastic deformation due to its material properties. It works in conjunction with damping gel 114 to reduce impact kinetic energy. It utilizes the compressibility of air to provide cushioning and forms a damping effect through throttling via small holes. The sponge pad layer 116, together with the protective layers of other first splicing plates 110, provides protection while reducing sound propagation and improving the comfort of the elevator car during use. By combining multiple protective materials in the first splicing plate 110, multiple energy dissipation from linear to nonlinear and from instantaneous to delayed can be achieved. At the same time, the first splicing plate 110 provides protection while reducing sound propagation and improving the comfort of the elevator car during use. The decorative layer 115 enhances the aesthetics of the device.

[0021] The second splicing panel 200 includes a second wooden board layer 210, with multiple sets of perforated support columns 220 fixedly connected to the lower side of the second wooden board layer 210. A rubber pad layer 230 is fixedly connected to the lower side of each perforated support column 220. A shear thickening liquid layer 240 is disposed inside each set of perforated support columns 220. The second wooden board layer 210 provides the first layer of protection for the second splicing panel 200. Simultaneously, the material of the second wooden board layer 210 reduces impact force. Furthermore, even if the surface of the second wooden board layer 210 is damaged, it will not easily scratch personnel. The perforated support columns 220 allow for absorption through plastic deformation. It dissipates impact energy by using a shear-thickening liquid layer 240 in conjunction with a hollow support column 220 to absorb the kinetic energy of the impact, thereby reducing the impact force on the elevator car. The rubber pad layer 230 reduces the noise generated during the impact, thus improving the comfort of using the elevator car. The second splicing plate 200 can also reduce the impact force on the elevator car. The rubber pad layer 230 reduces the noise generated during the impact, thus improving the comfort of using the elevator car.

Multiple sets of third fixing tubes 430 are fixedly connected to the upper side of the second fixing tube 420. A spring 440 is fixedly connected to the inner wall of the third fixing tube 430. A locking block 450 is fixedly connected to the side of the spring 440 near the first fixing tube 410. During use, the second fixing tube 420 is inserted into the first fixing tube 410, causing the locking block 450 inside the third fixing tube 430 to engage with the first fixing tube 410, thus completing the connection between the second fixing tube 420 and the first fixing tube 410. By setting the first connecting device 400, the second splicing plate 200 and the third splicing plate 300 can be quickly connected, improving the installation speed of this device. To enhance efficiency and convenience, a rotating rod 460 is rotatably connected to the upper and lower side walls of the second fixed tube 420.

The side of the steel wire rope 470 away from the rotating rod 460 is fixedly connected to the locking block 450. During use, the operator rotates the rotating rod 460, causing the steel wire rope 470 to wind around the lug of the rotating rod 460, thereby causing the first fixed tube 410 to detach from the second fixed tube 420. By setting up the steel wire rope 470, rotating rod 460, and locking block 450, the operator can easily and quickly disassemble the second splicing plate 200 and the third splicing plate 300, improving the practicality of the device. Slider blocks are fixedly connected to both the upper and lower sides of the locking block 450. The inner wall of the third fixed tube 430 is provided with a groove that matches the slider of the locking block 450.
