Description
Technical Field
[0001] This utility model relates to the field of elevator safety protection technology, and in particular to a built-in protective structure for elevator doors. Background Technology
[0002] As a key component for elevator interaction with the outside world, the elevator door is the core hub connecting the car space and building floors. Its design and performance directly determine the safety, convenience, and user experience of elevator use. From a functional perspective, it undertakes a dual interactive mission. On the one hand, through precise opening and closing control, it achieves efficient connection between the car and the floors, ensuring that passengers and goods can enter and exit smoothly. Whether it is the conventional opening and closing mode suitable for daily travel in residential buildings, or the wide opening and delayed closing function supported by public places such as shopping malls and hospitals, it can flexibly match the usage needs of different scenarios. On the other hand, as an important part of the elevator safety protection system, it integrates multiple intelligent protection mechanisms, such as infrared sensing and light curtain detection technologies, which can identify obstacles on the door's running path in real time. Once a person or object is detected approaching, it immediately triggers a deceleration or stop command to avoid the risk of collision. At the same time, the mechanical structure of the door is precisely calibrated and has stable locking performance, which can firmly isolate the inside and outside of the car during elevator operation, preventing accidental falls or pinching injuries, and building a solid defense for elevator safety.
[0003] In daily use, elevator doors are easily damaged by collisions and squeezing. For example, when passengers carry large items into or out of the elevator, the items may have a hard impact with the elevator door, causing dents and scratches on the elevator door surface, or even affecting the normal opening and closing function of the elevator door. At the same time, traditional elevator door protection structures are mostly external, which not only affects the aesthetics of the elevator door, but is also easy to fall off due to external forces, and the protection effect is limited. Therefore, we propose an internal protection structure for elevator doors. Utility Model Content
[0004] The purpose of this utility model is to provide an internal protective structure for elevator doors to solve the problem that elevator doors are easily damaged by collisions and squeezing during daily use. For example, when passengers carry large items into or out of the elevator, the items may have a hard impact with the elevator door, causing dents and scratches on the elevator door surface, or even affecting the normal opening and closing function of the elevator door. At the same time, traditional elevator door protective structures are mostly external, which not only affects the aesthetics of the elevator door, but is also easy to fall off due to external forces, and the protective effect is limited.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator door built-in protective structure, including an elevator door body, an installation cavity is provided inside the elevator door body, and a protective component is provided inside the installation cavity. The protective component includes a protective plate and a buffer plate. A protective opening is provided on the outer side of the elevator door body corresponding to the installation cavity. The protective plate is flush with the inner side of the elevator door body. Two sets of both the protective plate and the buffer plate are provided. The buffer plate is pasted on the side of the protective plate facing the outer side of the elevator door body.
[0006] As a preferred embodiment, fixing blocks are fixedly installed at the four corners of the surface of the protective plate, and the fixing blocks have threaded holes that penetrate the protective plate and the buffer plate. The protective plate is securely connected to the elevator door body by bolts passing through the threaded holes.
[0007] As a preferred embodiment, a diamond mesh is fixedly installed between the protective plate and the buffer plate.
[0008] As a preferred embodiment, both sets of the protective plates are provided with reinforcing ribs, and the reinforcing ribs are provided in a plurality of uniformly fixed installations on the inner side of the protective plates, and the plurality of sets of the reinforcing ribs are distributed in a grid pattern.
[0009] As a preferred embodiment, a number of evenly distributed buffer springs are fixedly installed between the two sets of protective plates and on the reinforcing ribs.
[0010] As a preferred embodiment, the protective plate is made of stainless steel and has good strength and wear resistance, while the buffer plate is made of rubber.
[0011] The technical effects and advantages of this utility model are as follows: The protective plate is made of stainless steel, which has excellent strength and wear resistance. It can directly block the hard impact generated when passengers carry large items into and out of the elevator, and prevent dents and scratches on the surface of the elevator door. The buffer plate is made of rubber, which can further absorb the impact force and reduce the damage to the elevator door. The design of two sets of protective plates and buffer plates expands the protection range and can prevent local impacts from damaging the elevator door and affecting its normal opening and closing function. In addition, this structure is built into the installation cavity of the elevator door body. The protective plate is flush with the inner side of the elevator door body and does not protrude from the surface of the elevator door, effectively ensuring the aesthetics of the elevator door. At the same time, the protective plate can be firmly connected to the elevator door body through the fixing block and bolts passing through the threaded hole, which greatly improves the structural stability. The diamond mesh fixed between the protective plate and the buffer plate enhances the impact resistance of the protective components without interfering with their normal protective functions, preventing sharp objects from piercing the protective components and damaging the elevator door body. Several evenly fixed grid-like reinforcing ribs on the inner side of the protective plate improve its structural strength, preventing deformation upon impact. Several buffer springs fixed between the two sets of protective plates and on the reinforcing ribs form elastic support between them. When the protective plate is impacted, the buffer springs assist the buffer plate in absorbing part of the impact force, further reducing the impact on the elevator door body. The coordinated operation of all components makes the entire protective structure more comprehensive and stable, effectively meeting the long-term protection needs of the elevator door body.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see the appendix Figure 1 - Appendix Figure 5 An elevator door built-in protective structure includes an elevator door body 1. An installation cavity is provided inside the elevator door body 1, and a protective component is provided inside the installation cavity. The protective component includes a protective plate 3 and a buffer plate 5. A protective opening 2 is provided on the outside of the elevator door body 1 at the position corresponding to the installation cavity. The protective plate 3 is flush with the inside of the elevator door body 1. Two sets of both the protective plate 3 and the buffer plate 5 are provided. The buffer plate 5 is pasted on the side of the protective plate 3 facing the outside of the elevator door body 1.
[0016] Both sets of protective plates 3 are provided with reinforcing ribs 4. Several reinforcing ribs 4 are provided and evenly fixedly installed on the inner side of the protective plate 3. The multiple sets of reinforcing ribs 4 are distributed in a grid pattern.
[0017] Several evenly distributed buffer springs 8 are fixedly installed between the two sets of protective plates 3 and on the reinforcing ribs 4. The protective plates 3 are made of stainless steel and have good strength and wear resistance, while the buffer plates 5 are made of rubber.
[0018] Specifically, the built-in protective structure of this elevator door effectively solves the problem of elevator doors being easily damaged by collisions and squeezing during daily use. Multiple protective components are used to achieve multiple layers of protection. The protective plate 3 is made of stainless steel and has good strength and wear resistance, directly blocking hard impacts caused by passengers carrying large items into and out of the elevator, preventing dents and scratches on the surface of the elevator door body 1. The buffer plate 5 is made of rubber, which further absorbs impact force and reduces damage to the elevator door body 1. The design of two sets of protective plates 3 and buffer plates 5 expands the protection range, preventing localized impacts from damaging the elevator door body 1 and affecting its normal opening and closing function. Compared to traditional external protective structures, this structure is built into the mounting cavity of the elevator door body 1, with the protective plate 3 flush with the inner side of the elevator door body 1, not protruding from the elevator door surface, effectively ensuring the aesthetics of the elevator door. Furthermore, the protective plate 3 is securely connected to the elevator door body 1 by the fixing block 6 and bolts passing through the threaded holes 7, avoiding the problem of traditional external protective structures easily falling off due to external forces, significantly improving the protective effect.
[0019] Please see the appendix Figure 1 - Appendix Figure 4 Fixing blocks 6 are fixedly installed at the four corners of the surface of the protective plate 3. The fixing blocks 6 have threaded holes 7 that penetrate the protective plate 3 and the buffer plate 5. The protective plate 3 is securely connected to the elevator door body 1 by bolts passing through the threaded holes 7.
[0020] A diamond mesh 9 is fixedly installed between the protective plate 3 and the buffer plate 5.
[0021] Specifically, this structure enhances overall protective performance and stability through the coordinated operation of multiple components, further addressing the limited protective effect of traditional protective structures. The diamond mesh 9 fixedly installed between the protective plate 3 and the buffer plate 5 enhances the impact resistance of the protective components without affecting their normal protective functions, preventing sharp objects from piercing the protective components and damaging the elevator door body 1. Several reinforcing ribs 4 evenly fixedly installed on the inner side of the protective plate 3 in a grid pattern can improve the structural strength of the protective plate 3 itself, preventing the protective plate 3 from deforming when impacted. Several buffer springs 8 fixedly installed between the two sets of protective plates 3 and on the reinforcing ribs 4 can form elastic support between the two sets of protective plates 3. When the protective plate 3 is impacted, the buffer springs 8 can assist the buffer plate 5 in absorbing part of the impact force, further reducing the impact on the elevator door body 1. The cooperation of each component makes the protective performance of the entire protective structure more comprehensive and stable, effectively meeting the long-term protection needs of the elevator door body 1.
[0022] Working principle of this utility model: This utility model is a built-in protective structure for elevator doors. When an external impact occurs, such as when a passenger carrying a large item impacts the elevator door, the impact first acts on the protective plate 3, which is flush with the inner side of the elevator door body 1. Because the protective plate 3 is made of stainless steel and has a mesh-like reinforcing rib 4 on its inner side, its own strength and wear resistance can directly block hard impacts, preventing dents and scratches on the surface of the elevator door body 1. At the same time, the reinforcing rib 4 can prevent the protective plate 3 from deforming due to impact. If the impact force continues to be transmitted, the rubber buffer plate 5 attached to the outer side of the protective plate 3 facing the elevator door body 1 will further absorb part of the impact force, reducing the direct damage to the elevator door body 1. The diamond mesh 9 between the buffer plates 5 can enhance the impact resistance of the protective components and prevent sharp objects from piercing the protective components. When the impact force is large, the buffer spring 8 between the two sets of protective plates 3 and fixed on the reinforcing rib 4 will form an elastic support. Through its own deformation, it will assist the buffer plate 5 in absorbing the remaining impact force, avoiding local impact that could damage the elevator door body 1 and affect the normal opening and closing function. During the entire protection process, the protective components are firmly connected to the installation cavity of the elevator door body 1 by the fixing block 6 and the bolts passing through the threaded hole 7. The protective plate 3 does not protrude from the surface of the elevator door. While achieving multiple protections, it also ensures the aesthetics of the elevator door and avoids the problem of easy detachment of traditional external protective structures. At this point, the entire process is complete.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
