Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and more particularly to an elevator door panel positioning structure. Background Art

[0002] The elevator door panel positioning structure is an important part of the elevator door system. Its main function is to ensure that the elevator door can stay accurately at the set position during the opening and closing process, ensure that the door body and the floor are well connected, and avoid deviation or jamming. Usually, this positioning structure is realized through guide rails, positioning pins or spring components to ensure that the door panel is positioned smoothly and accurately during operation, avoiding the normal function of the elevator door being affected by asymmetric forces or structural problems.

[0003] In terms of design, the positioning structure of the elevator door panel needs to take into account durability and high precision to ensure that the positioning device can still work stably even in an environment of frequent opening and closing. Modern elevator doors often use a combination of mechanical and electronic control, and through precise sensors and automatic adjustment systems, further improve the accuracy and response speed of door panel positioning, thereby improving the safety and comfort of the elevator.

[0004] Existing elevator door panels include elevator car door panels and elevator floor door panels. After the elevator car reaches a floor, the elevator car door panels and the elevator floor door panels need to be positioned and aligned with each other before opening and closing.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0030] The first implementation method:

[0031] See also Figure 1-6, an elevator door panel positioning structure comprises an elevator car 1, a pair of door panel positioning plates 5, a pair of positioning plates 8 and a pair of dust removal components 10, a pair of car door panels 2 are installed inside the front end of the elevator car 1, a floor door frame 3 is provided at the front end of the elevator car 1, a pair of floor door panels 4 are installed at the inner end of the floor door frame 3, a pair of door panel positioning plates 5 are respectively fixedly connected to the lower ends of the elevator car 1 and the floor door frame 3, and the car door panel 2 and the floor door panel 4 are both located at the upper end of the door panel positioning plates 5, a guide rail groove 6 is opened at the upper end of the door panel positioning plates 5, a pair of door panel guide rails 7 are slidably connected to the inner end of the guide rail groove 6, and two pairs of door panel guide rails 7 are respectively fixedly connected to the lower ends of a pair of car door panels 2 and a pair of floor door panels 4, a pair of door panel positioning plates 5 are each provided with a collection groove at one end close to each other, a pair of positioning plates 8 are respectively slidably connected to a pair of collection grooves, and an electromagnetic plate is fixedly connected to the inner end of the collection groove 9. A pair of dust removal components 10 are respectively fixedly connected to the inner walls of a pair of storage grooves, and the dust removal components 10 are located between the positioning plate 8 and the electromagnetic plate 9 and fixedly connected thereto. When a pair of car door panels 2 and a pair of floor door panels 4 are closed, a pair of electromagnetic plates 9 are respectively activated to be magnetized, and the magnetic force of the electromagnetic plate 9 is used to attract the positioning plate 8, so that the pair of positioning plates 8 move back to back and are retracted into the storage groove. When the car door panels 2 and the floor door panels 4 are opened, the power supply of the electromagnetic plate 9 is disconnected to make it lose its magnetic force, so that the pair of positioning plates 8 move closer to each other. If the car door panels 2 and the floor door panels 4 are horizontal, it is normal for the pair of positioning plates 8 to abut against each other. If they are not in the same horizontal plane, the pair of positioning plates 8 do not abut against each other, so that the positioning plates 8 continue to extend, causing themselves to change color under stress, and a reminder is given according to the color change, so that attention should be paid to this.

[0032] The positioning plate 8 includes a telescopic slide 81, which is slidably connected to the storage groove. The end of the telescopic slide 81 close to the electromagnetic plate 9 is fixedly connected to the magnetic back plate 82, and the end of the telescopic slide 81 away from the magnetic back plate 82 is fixedly connected to the strain color display plate 83. A pair of storage grooves are close to each other. The inner walls of one end are fixedly connected with a deformable membrane 87. The pair of telescopic slides 81 can be used to block the gap between the car door panel 2 and the floor door panel 4, and the abutment between the pair of strain color display plates 83 can effectively position the position between the car door panel 2 and the floor door panel 4 to maintain the same horizontal height. When the pair of telescopic slides 81 slide out and abut each other, the deformation membrane 87 is normally stretched and deformed. If the pair of telescopic slides 81 slide apart, the telescopic slide 81 will continue to slide out, and after the deformation membrane 87 reaches the maximum deformable value, it will squeeze the strain color display plate 83.

[0033] The positioning plate 8 also includes a pair of limiting guide grooves 84, which are opened on the inner wall of the storage groove. A limiting guide block 85 is slidably connected in the limiting guide groove 84. An action spring 86 is fixedly connected between the limiting guide block 85 and the inner wall of the limiting guide groove 84. After the electromagnetic plate 9 loses its magnetic force, the limiting guide block 85 is pushed under the action of the elastic force of the action spring 86, so that the pair of limiting guide blocks 85 drive the telescopic slide 81 to slide out of the storage groove.

[0034] The positioning plate 8 also includes a pressure bag 88, which is fixedly connected to the upper end of the telescopic slide 81, and the pressure bag 88 is located in the limiting guide groove 84. The pressure bag 88 is filled with electrorheological fluid. An inflatable bag 89 is inlaid on the upper end of the telescopic slide 81, and the inflatable bag 89 is located on the side of 88 away from the limiting guide block 85. The pressure bag 88 is connected to the inflatable bag 89. When the telescopic slide 81 completely slides out of the storage groove, the inner wall of the groove squeezes the pressure bag 88, so that the electrorheological fluid in the pressure bag 88 is forced to flow into the inflatable bag 89, so that the inflatable bag 89 bulges on the upper end of the telescopic slide 81 in a cushion shape. When the electrorheological fluid is energized, the inflatable bag 89 is hardened, so that it is used as a step to provide convenience for users. It should be noted that a gap is left between the deformation membrane 87 and the upper inner wall of the storage groove, so that the inflatable bag 89 can bulge out of the gap.

[0035] The strain color display plate 83 includes a substrate frame 831, which is fixedly connected to the end of the telescopic slide 81 away from the magnetic back plate 82, and the inner end of the substrate frame 831 is fixedly connected to a color changing plate 832, and the end of the color changing plate 832 away from the magnetic back plate 82 is provided with an extrusion plate 833, and the extrusion plate 833 is slidably connected to the substrate frame 831, and the upper and lower ends of the extrusion plate 833 are fixedly connected to soft cotton strips 834, and the soft cotton strips 834 are fixedly connected to the inner wall of the substrate frame 831. When the maximum critical point of deformation is reached through the deformation membrane 87, force is applied to the extrusion plate 833 to make it slide and apply force to the color changing plate 832, so that the color changing plate 832 is subjected to force and changes color.

[0036] The strain color display plate 83 also includes a plurality of extrusion protrusions 835, and the plurality of extrusion protrusions 835 are fixedly connected to one end of the extrusion plate 833 close to the color changing plate 832, and the plurality of extrusion protrusions 835 are fixedly connected to the color changing plate 832. The plurality of extrusion protrusions 835 can effectively disperse the force acting on the extrusion plate 833 to squeeze the color changing plate 832, thereby making the color change of the color changing plate 832 more obvious.

[0037] The strain color display board 83 also includes a magnifying panel 836, which is fixedly connected to the upper end of the substrate frame 831 and is located at the upper end of the color changing board 832. The magnifying panel 836 can be used to more clearly display the color changing board 832 after color change, thereby more effectively serving as a reminder.

[0038] The color-changing plate 832 is made of liquid crystal color-changing material. When the liquid crystal color-changing material is subjected to external pressure or deformation, the molecular arrangement may change, thereby changing the reflection or refraction of light, which manifests as a change in color. After the external force is removed, the liquid crystal color-changing material will restore its original arrangement and color. The extrusion protrusion 835 is made of hard silicone. The hard silicone material is used to make the extrusion protrusion 835 have a certain hardness for extrusion, and at the same time, it can also prevent damage to the color-changing plate 832 due to its excessive hardness. The magnifying panel 836 is a convex lens, and the convex lens can effectively magnify the color-changing plate 832 after the color change.

[0039] The dust removal component 10 includes a deformable airbag 101, which is fixedly connected between the positioning plate 8 and the electromagnetic plate 9. A first mounting groove is provided on the inner wall of the storage groove, and the first mounting groove is communicated with the guide rail groove 6. An exhaust pipe 102 is fixedly connected in the first mounting groove, and the exhaust pipe 102 is fixedly connected to the deformable airbag 101. A one-way valve 103 is fixedly connected to the inner wall of the exhaust pipe 102. The deformable airbag 101 is squeezed by the positioning plate 8 when the storage groove is retracted, so that the gas in the deformable airbag 101 is squeezed into the exhaust pipe 102 and sprayed out to clean the dust and impurities in the guide rail groove 6. The one-way valve 103 can prevent the deformable airbag 101 from sucking air from the guide rail groove 6 to suck dust and impurities into the deformable airbag 101 when it is inflated and restored.

[0040] The dust removal assembly 10 also includes an air intake pipe 104, and a second mounting groove is provided on the lower inner wall of the storage groove. The air intake pipe 104 is fixedly connected to the second mounting groove, and the air intake pipe 104 is fixedly connected to the deformable airbag 101. A second one-way valve 105 is inlaid on the lower end of the door panel positioning plate 5, and the second one-way valve 105 is fixedly connected to the air intake pipe 104. The air intake pipe 104 can provide the deformable airbag 101 with air inhaled from the outside, and the second one-way valve 105 can prevent the gas from being discharged from the air intake pipe 104 when the deformable airbag 101 is squeezed.

[0041] A cleaning wipe 11 is fixedly connected to the upper inner wall of the opening of the storage groove, and the cleaning wipe 11 is in contact with the positioning plate 8. The cleaning wipe 11 can be used to wipe and clean the surface of the magnifying panel 836 when the positioning plate 8 slides out and is retracted, so that the magnifying panel 836 remains clear.

[0042] Working principle:

[0043] When the elevator car 1 is lifted and moved to a horizontal position with the floor door frame 3, when a pair of car door panels 2 and a pair of floor door panels 4 are opened, the electromagnetic plate 9 is disconnected from the power supply and loses its magnetic force, and the limiting guide block 85 is pushed to slide along the limiting guide groove 84 under the elastic force of a pair of action springs 86, and at the same time, the telescopic slide plate 81 is driven to slide out of the storage groove, so that the pair of strain color display plates 83 move close to each other and abut against each other. If the car door panel 2 and the floor door panel 4 are in the horizontal position, the pair of strain color display plates 83 abut against each other and do not change color, which is normal. If they are not in the same horizontal plane, the pair of strain color display plates 83 are staggered and do not abut against each other, so that the pair of strain color display plates 83 will continue to be driven by the telescopic slide plate 81 to slide out of the storage groove until the deformation membrane 87 can no longer deform, and the deformation membrane 87 is used to squeeze the strain color display plate 83 inward, so that the color of the strain color display plate 83 changes. , so as to achieve the purpose of reminder, and with the help of the completely slid out positioning plate 8, when the telescopic slide plate 81 completely slides out of the storage groove, the inner wall of the groove squeezes the pressure bag 88, so that the electrorheological fluid in the pressure bag 88 is forced to flow into the inflatable bag 89, so that the inflatable bag 89 bulges on the upper end of the telescopic slide plate 81 in a cushion shape, and the electrorheological fluid is energized to harden the inflatable bag 89, so as to use it as a step to provide convenience for users; then when the car door panel 2 and the floor door panel 4 are closed, the electromagnetic plate 9 is activated to magnetize the magnetic back plate 82, so that the telescopic slide plate 81 slides back into the storage groove, and a pair of limit guide blocks 85 compress the action spring 86, and in the process of retracting the telescopic slide plate 81, the deformable airbag 101 is squeezed, and the gas in the deformable airbag 101 is squeezed to the exhaust pipe 102 and sprayed out to clean the dust and impurities in the guide groove 6.

[0044] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0045] The present invention aims to position the horizontal positions of the car door panel 2 and the floor door panel 4 through a pair of positioning plates 8. When the car door panel 2 and the floor door panel 4 are opened, the pair of positioning plates 8 are moved close to each other for abutment, and the horizontal state of the positions of the car door panel 2 and the floor door panel 4 is determined according to whether the color of the strain color display plate 83 changes. When they are in the same horizontal plane, the pair of strain color display plates 83 abut against each other and do not show color. When the pair of strain color display plates 83 are staggered in a non-horizontal state, the strain color display plates 83 are stressed and the color changes, thereby requiring attention to safety and reminding the staff that maintenance is needed. At the same time, during the sliding out and retraction process of the positioning plate 8, the dust removal component 10 is driven to clean the inside of the guide rail groove 6, thereby greatly improving the safety and stability of the overall operation of the elevator.
