Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator car technology, and in particular to an elevator car with a protective structure. Background Technology
[0002] The elevator car is the box-shaped space used to carry and transport people and goods, and its internal protection is particularly important during the decoration phase. Currently, most new residential elevator cars use rigid panels (such as wood or metal plates) directly fixed to the inner wall as a protective layer to prevent damage to the car during the handling of decoration materials. However, this traditional solution has significant drawbacks: First, rigid panels have no cushioning capacity, and the impact force of decoration materials is directly applied to the car when they hit it, easily causing structural damage to the car; second, fragments from the brittle materials after impact can easily get stuck in the gap between the car and the elevator shaft, posing a safety hazard; third, the panel covering obstructs ventilation in the car, affecting passenger comfort.
[0003] To address the aforementioned issues, this invention proposes an elevator car with a protective structure. Through a combination of a double-spring buffer structure, an elastic protective frame gap design, and an induced draft fan ventilation system, it achieves efficient protection and environmental optimization for the elevator car. Compared to existing technologies, this solution significantly improves impact force attenuation, material shatter resistance, and ventilation performance, effectively resolving the protection challenges of elevator cars during the renovation phase. Utility Model Content
[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose an elevator car with a protective structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An elevator car with a protective structure includes a main frame. Protective covers are fixed to the upper left and right ends of the main frame, and induced draft fans are fixed inside the protective covers. Limit plates are fixed to the left and right sides of the front end of the main frame. A protective frame is embedded inside the main frame. The protective frame is made of Q235B steel and has a load-bearing capacity of ≥500N. A handrail is fixed to the lower part of the protective frame, and a top plate is fixed to the top of the protective frame. Buffer seats are fixed to the left, right, and rear ends of the main frame. Buffer springs and connecting columns are embedded inside the buffer seats. A guide plate is fixed to the end of each connecting column near the middle of the main frame. Limit rods are embedded inside the guide plates, and pressure springs are nested outside the limit rods.
[0007] Preferably, the front end of the protective frame is in close contact with the limiting plate, and the distance between the outer wall of the protective frame and the inner wall of the main frame is 1 to 2 centimeters.
[0008] Preferably, the internal opening of the protective frame is provided with ventilation holes, and the exhaust pipe of the blower is embedded in the gap between the outer wall of the protective frame and the inner wall of the main frame.
[0009] Preferably, the protective frame has a transverse groove in the rear end of its interior, and longitudinal grooves in the interior of both the left and right sides of the protective frame. The limiting rod is fixed in the transverse groove and the longitudinal groove, respectively.
[0010] Preferably, the guide plate at one end of the connecting column slides horizontally left and right outside the limiting rod of the transverse slide groove, and the guide plate at one end of the connecting column slides horizontally back and forth outside the limiting rod of the longitudinal slide groove.
[0011] Preferably, the end of the connecting column away from the middle of the main frame is connected to the buffer spring, and the buffer seat in the connecting column slides horizontally inside.
[0012] 1. When decorative materials accidentally impact the rear end of the main frame during use, the protective frame will come into contact with the decorative materials. After being subjected to force, the protective frame moves backward, compressing the buffer spring in the rear buffer seat. At the same time, the connecting columns at the left and right ends move backward, compressing and pulling the pressure spring on its outer wall to deform. When decorative materials accidentally impact the left or right ends of the main frame, the protective frame will move to the left or right, compressing the buffer spring in the left or right buffer seat. At the same time, the connecting columns at the rear end slide left and right, compressing and pulling the pressure spring on its outer wall to deform. Thus, regardless of whether the protective frame is subjected to impact force from the left or right ends or the rear end, the deformation of the buffer spring and pressure spring can buffer the impact force received by the protective frame, preventing the impact force from acting directly on the car through the plate. This provides better protection for the car and reduces the damage rate of decorative materials caused by rigid impact, making it more convenient to use.
[0013] 2. During use, the two exhaust fans will work continuously to draw air from the elevator shaft into the gap between the protective frame and the main frame. Then, this airflow will pass through the protective frame and be discharged from the exhaust holes inside the protective frame, entering the interior of the car. This prevents the car from feeling stuffy due to the protective structure, further optimizing the passenger's riding experience. Attached Figure Description

[0018] Legend:
[0019] Main frame 1, protective cover 2, induced draft fan 201, limit plate 3, protective frame 4, handrail 401, top plate 402, buffer seat 5, buffer spring 501, connecting column 502, guide plate 503, limit rod 504, pressure spring 505. Detailed Implementation
[0020] Example 1, referring to Figure 1-4 An elevator car with a protective structure includes a main frame 1. The main frame 1 has protective covers 2 fixed to its upper left and right ends, and a blower 201 fixed inside each of the protective covers 2. Limit plates 3 are fixed to the left and right sides of the front end of the main frame 1. A protective frame 4 is embedded inside the main frame 1. The protective frame 4 is made of Q235B steel and has a load-bearing capacity of ≥500N. A handrail 401 is fixed to the lower part of the protective frame 4. A top plate 402 is fixed to the top of the protective frame 4. Buffer seats 5 are fixed to the left, right, and rear ends of the main frame 1. Buffer springs 501 and connecting columns 502 are embedded inside the buffer seats 5. A guide plate 503 is fixed to one end of the connecting column 502 near the middle of the main frame 1. Limit rods 504 are embedded inside the guide plates 503, and pressure springs 505 are nested on the outside of the limit rods 504.
[0021] The front end of the protective frame 4 is in close contact with the limiting plate 3, and the distance between the outer wall of the protective frame 4 and the inner wall of the main frame 1 is 1~2 cm;
[0022] The main function of the limiting plate 3 is to prevent foreign objects from getting stuck in the gap between the protective frame 4 and the main frame 1, thus affecting the normal forward, backward and left and right movement of the protective frame 4.
[0023] The protective frame 4 has ventilation holes inside, and the exhaust pipe of the blower 201 is embedded in the gap between the outer wall of the protective frame 4 and the inner wall of the main frame 1.
[0024] During use, the two exhaust fans 201 will work continuously to introduce air from the elevator shaft into the gap between the protective frame 4 and the main frame 1. Then, this airflow will pass through the protective frame and be discharged from the exhaust port inside the protective frame 4, and enter the interior of the car, so that the interior of the car will not feel stuffy due to the protective structure, further optimizing the riding experience of passengers.
[0025] Example 2 differs from Example 1 in that, in this example, the rear end of the protective frame 4 has a transverse groove for the transverse opening, and the left and right sides of the protective frame 4 have longitudinal grooves for the longitudinal openings. The limiting rod 504 is fixed in the transverse groove and the longitudinal groove respectively.
[0026] The guide plate 503 at one end of the connecting column 502 slides horizontally left and right outside the limiting rod 504 of the transverse slide groove, and the guide plate 503 at one end of the connecting column 502 slides horizontally back and forth outside the limiting rod 504 of the longitudinal slide groove.
[0027] One end of the connecting column 502 away from the middle of the main frame 1 is connected to the buffer spring 501, and the buffer seat 5 in the connecting column 502 slides horizontally inside;
[0028] When the decoration materials are placed in the car and accidentally hit the rear end of the main frame 1, the protective frame 4 will come into contact with the decoration materials. After the protective frame 4 is subjected to force, it moves backward. The connecting column 502, guide plate 503 and limit rod 504 compress the buffer spring in the buffer seat 5 at the rear end. At the same time, the connecting column 502 at the left and right ends moves backward, compressing and pulling the pressure spring 505 on its outer wall to deform. The impact force received by the protective frame 4 is buffered by the deformation of the buffer spring 501 and the pressure spring 505.
[0029] When the decoration materials placed inside the car accidentally impact the left or right ends of the main frame 1, the protective frame 4 will move to the left or right. The connecting column 502, guide plate 503, and limit rod 504 will compress the buffer spring 501 in the left or right buffer seat 5. At the same time, the connecting column 502 at the rear end slides left and right, compressing and pulling the pressure spring 505 on its outer wall to deform. Thus, no matter whether the protective frame 4 is subjected to impact force from the left or right end or the rear end, the deformation of the buffer spring 501 and the pressure spring 505 can buffer the impact force received by the protective frame 4, preventing the impact force from acting directly on the car through the plate. This provides better protection for the car, and the decoration materials are less likely to break and be damaged accidentally, making it more convenient to use.
[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
