Description

Technical Field

[0001] This utility model relates to the field of elevator car technology, and in particular to an elevator car structure. Background Technology

[0002] The elevator car is a box-shaped space used to carry and transport people and goods. The car generally consists of main components such as the car floor, car walls, car top, and car doors. It is the elevator body component used to transport passengers, goods, and other loads. Currently, in traditional elevator cars, when the elevator stops and the doors open, there is a gap between the elevator car and the floor. When pushing trolleys or other items into the car, this gap can easily get the trolley's bottom pulleys stuck, making it inconvenient to use. Furthermore, when a traditional elevator car stops and impacts the wall due to inertia, and given the presence of buttons and wiring inside, the elevator car is easily damaged by the impact, indicating poor impact resistance.

[0003] To address the aforementioned issues, existing patent (CN222892866U) discloses a dual-structure elevator car, comprising an outer car and an inner car. The inner car has two rotating plates on its sides, connected to the inner car via a pivot. A sliding plate is embedded within each rotating plate, with a first slider and a second slider fixedly connected to its side. A groove is formed on the side of the rotating plate. This dual-structure elevator car, by adding rotating plates to the inner car's side, allows for easy maneuvering when trolleys or similar items need to be pushed into the elevator. Simply lower the rotating plate and pull out the sliding plate, causing the first and second sliders to slide within the rotating plate, connecting it to the floor. This allows the trolley to retract from the sliding plate surface into the elevator car. After use, the sliding plate is pushed back to its original position, and the rotating plate is lifted to rest against the side of the inner car, making it more convenient to use.

[0004] However, in the aforementioned existing technologies, the poor ventilation inside the elevator car can cause users to feel stuffy when riding the elevator, affecting their riding experience and posing safety hazards. Utility Model Content

[0005] The purpose of this utility model is to provide an elevator car structure that solves the technical problem in the prior art where poor ventilation inside the elevator car leads to a stuffy feeling for users, affecting the riding experience and posing safety hazards.

[0006] To achieve the above objectives, this utility model employs an elevator car structure, including a car body and a circulation mechanism. The circulation mechanism includes an upper ventilation duct, a lower exhaust duct, and a ventilation component. The upper ventilation duct is fixedly connected to the car body and located above it. The lower exhaust duct is fixedly connected to the car body and located outside it. The ventilation component includes a first barrier, a fixing frame, a first axial flow fan, a second barrier, a second axial flow fan, and a protective component. The first barrier is fixedly connected to the upper ventilation duct and located inside it. The fixing frame is fixedly connected to the upper ventilation duct and located below it. The first axial flow fan is fixedly connected to the fixing frame and located inside it. The second barrier is fixedly connected to the lower exhaust duct and located inside it. The second axial flow fan is fixedly connected to the lower exhaust duct and located outside it.

[0020] This utility model provides an elevator car structure, including a car body 101 and a circulation mechanism. The circulation mechanism includes an upper ventilation duct 102, a lower exhaust duct 103, and a ventilation component. The ventilation component includes a first barrier 104, a fixing frame 105, a first axial flow fan 106, a second barrier 107, a second axial flow fan 108, and protective components. The protective components include a filter screen 109, an external pull frame 110, a third barrier 111, a fourth barrier 112, a fixing box 113, a telescopic frame 114, a limiting block 115, and a telescopic spring 116. The aforementioned solution solves the problem that poor ventilation inside the elevator car can cause passengers to feel stuffy when riding the elevator, affecting their riding experience and posing safety hazards.

[0021] In this specific embodiment, the circulation mechanism includes an upper ventilation duct 102, a lower exhaust duct 103, and a ventilation assembly. The upper ventilation duct 102 is fixedly connected to the car body 101 and located above the car body 101. The lower exhaust duct 103 is fixedly connected to the car body 101 and located outside the car body 101. The ventilation assembly includes a first barrier 104, a fixing frame 105, a first axial flow fan 106, a second barrier 107, and a second axial flow fan 108. The fan 108 and protective components are provided. The first barrier 104 is fixedly connected to the upper ventilation duct 102 and located within the upper ventilation duct 102. The fixing frame 105 is fixedly connected to the upper ventilation duct 102 and located below the first barrier 104. The first axial fan 106 is fixedly connected to the fixing frame 105 and located within the fixing frame 105. The second barrier 107 is fixedly connected to the lower exhaust duct 103 and located within the lower exhaust duct 103. The second axial flow fan 108 is fixedly connected to the lower exhaust duct 103 and located outside the second barrier 107. The protective component is detachably connected to the upper ventilation duct 102 and located below the first axial flow fan 106. The fixing bracket 105 is disposed in the upper ventilation duct 102 and fixes the first axial flow fan 106. The first axial flow fan 106 draws air from the elevator shaft into the car body 101 through the upper ventilation duct 102. The first barrier 104 prevents foreign objects from entering the car body 101 through the upper ventilation duct 102. The second axial flow fan 108 is disposed in the lower exhaust duct 103 and exhausts the air inside the car body 101 downwards. The second barrier 107 prevents personnel's hands from entering the lower exhaust duct 103. This method can effectively solve the problem that poor ventilation inside the elevator car can cause users to feel stuffy when riding the elevator.

[0022] The protective component includes a filter screen 109 and an outer pull bracket 110. The filter screen 109 is detachably connected to the upper ventilation duct 102 and is located below the first axial flow fan 106. The outer pull bracket 110 is fixedly connected to the filter screen 109 and is located outside the filter screen 109. The filter screen 109 filters the air entering the car body 101 from the outside, allowing surface dust to enter. The outer pull bracket 110 facilitates the pulling out and replacement of the filter screen 109.

[0023] Secondly, the protective component also includes a third barrier 111 and a fourth barrier 112. The third barrier 111 is fixedly connected to the upper ventilation duct 102 and is located above the filter screen 109. The fourth barrier 112 is fixedly connected to the upper ventilation duct 102 and is located below the filter screen 109. The third barrier 111 works in conjunction with the fourth barrier 112 to restrict the filter screen 109.

[0024] Meanwhile, the protective component also includes a fixed box 113 and a telescopic frame 114. The fixed box 113 is fixedly connected to the car body 101 and is located outside the outer pull frame 110. The telescopic frame 114 is slidably connected to the fixed box 113 and passes through the fixed box 113. The telescopic frame 114 is disposed in the fixed box 113.

[0025] In addition, the protective component also includes a limiting block 115 and a telescopic spring 116. The limiting block 115 is detachably connected to the filter screen 109 and is located on the outside of the telescopic frame 114. The telescopic spring 116 is fixedly connected to the limiting block 115 and is located inside the fixing box 113. The limiting block 115 restricts the filter screen 109 to prevent it from being directly removed. When the telescopic frame 114 is pulled outward, the limiting block 115 compresses the telescopic spring 116, and the limiting block 115 releases its restriction on the filter screen 109, allowing the filter screen 109 to be quickly removed. After the telescopic frame 114 is released, the telescopic spring 116 pushes the limiting block 115 back to its original position to restrict the filter screen 109.

[0026] Using an elevator car structure according to this embodiment, by setting the upper ventilation duct 102, the lower exhaust duct 103, and the ventilation components, in specific use, the first axial flow fan 106 draws air from the elevator shaft into the car body 101 through the upper ventilation duct 102. The first barrier 104 prevents external foreign objects from entering the car body 101 through the upper ventilation duct 102. The filter 109 filters the incoming air, thereby preventing external dust from entering the interior of the car body 101. The second axial flow fan 108 is set in the lower exhaust duct 103, and the second axial flow fan 108 exhausts the air inside the car body 101 downwards. The second barrier 107 prevents personnel's hands from entering the lower exhaust duct 103. Thus, the upper ventilation duct 102 and the lower exhaust duct 103 form a circulation, thereby achieving smooth ventilation inside the car body 101 and effectively improving the passenger's riding experience.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model.
