Higher requirements are put forward for the safety, reliability and comfort of elevators, and the protective structure of the car body has also been continuously developed and improved.
[0003] However, the traditional protective structure for an elevator car body may not have an ideal buffering effect for elevator emergency stops or accidental impacts, resulting in a greater impact force on passengers. At the same time, the materials and structural designs used may not be able to effectively prevent the spread of fire during a fire, and it is difficult to buy enough time for passengers to escape. The ventilation system may not be able to ensure good air circulation inside the car body, and the structures used may be prone to fatigue, deformation or corrosion after long-term use, affecting the stability of the car body.
[0004] Therefore, aiming at the problems of poor stability, limited buffering performance and poor fire protection performance of the traditional protective structure for an elevator car body, a protective structure for an elevator car body can be designed. By adding inner and outer support plates and a buffer component, the overall rigidity and load-bearing capacity of the car body can be significantly improved, making it more capable of withstanding various external forces and loads, reducing the risk of car body deformation, increasing the stability of the car body, reducing shaking and vibration, and improving the riding comfort of passengers. When the elevator makes an emergency stop, falls due to a malfunction or is accidentally collided, the buffer component can absorb and slow down the huge impact force, reducing the harm to the car body and passengers. Summary of the Utility Model

Inside the car cover 1, a passenger-carrying frame 6 is arranged. Inside the top of the car cover 1, a fire-extinguishable water tank 2 with a smoke sensor is installed. On the right side of the water tank 2, a negative pressure fan 3 is provided to replace the internal air. Inside the car cover 1, an airbag assembly that can be triggered by collision is installed. The airbag at the bottom is a low-speed airbag 4 to prevent secondary injuries. The airbag assembly is externally sheathed with an inner support plate 5 to increase the support strength of the passenger-carrying frame 6. Inside the bottom of the car cover 1, a buffer assembly is installed, and outer support plates 7 are installed on both sides of the buffer assembly. By adding the inner and outer support plates 7 and the buffer assembly, the overall rigidity and load-bearing capacity of the car body can be significantly improved, enabling it to better withstand various external forces and loads, reducing the risk of car body deformation, increasing the stability of the car body, reducing shaking and vibration, and enhancing the riding comfort of passengers. When the elevator suddenly stops, fails and falls, or is accidentally collided, the buffer assembly can absorb and slow down the huge impact force, reducing the harm to the car body and passengers. On the upper right side of the car cover 1, a ventilation slot 14 is opened. On the front surface of the car cover 1, an assembly slot 15 is opened for installing the negative pressure fan 3, which can promote the air exchange inside and outside the car body, keep the air inside the car fresh, and improve the comfort of passengers. Embedding the equipment into the assembly slot 15 makes the surface of the car body more flat and beautiful, enhancing the overall visual effect, and can conveniently install equipment such as a control panel, a display screen, and an emergency call button, making the installation of these equipment more neat and standardized.
[0030] Please refer to Figures 4 - 5 , in this embodiment, connection platforms 9 for connecting with the passenger-carrying frame 6 are installed at the four corners of the bottom of the water tank 2. Four spray water taps 10 are installed at the bottom of the water tank 2. A smoke alarm is arranged at the bottom of the water tank 2. Support components are installed at the four corners of the bottom of the water tank 2 to enable the water tank 2 to be placed more stably, reducing shaking and tilting caused by an uneven frame or external forces. The smoke alarm and the spray water pipe cooperate to timely detect a possible fire at the bottom of the water tank 2, give an alarm before the fire spreads, and at the same time, the spray water pipe sprays water to extinguish the fire, preventing the spread of the fire and improving safety. On the right side of the negative pressure fan 3, a grille 12 is movably installed. On the left side of the negative pressure fan 3, it is movably connected to the hole on the right side of a Y-shaped ventilation pipe 13 arranged between the water tank 2 and the passenger-carrying frame 6. The grille 12 can prevent larger objects or foreign matters from entering the negative pressure fan 3. The movably installed grille 12 is convenient for disassembly, easy to clean and maintain the fan and the surrounding area, enabling the negative pressure fan 3 to effectively extract air from the area inside the passenger-carrying frame 6 and improving the overall ventilation condition.
[0031] Please refer to Figures 6 - 8, in this embodiment, the airbag assembly includes a low-speed airbag 4 and a vertical airbag 8. Three vertical airbags 8 are installed above the low-speed airbag 4. The surface of the vertical airbag 8 is sprayed with fireproof material. The three vertical airbags 8 increase the coverage area of the airbag. Whether it is a frontal, side or overhead collision impact, it can provide more comprehensive buffer protection for passengers, can cope with collisions from different angles and directions, improve the protection ability of the compartment in complex accidents, ensure that the airbag can still maintain its structural integrity and buffer performance in a high-temperature environment, effectively play a protective role, prevent harmful gases and smoke from being generated by the combustion of the airbag, and reduce the risk of secondary injury to passengers. There are square ventilation openings on the upper surface of the manned frame 6, and circular water holes are opened on the left and right sides of the square ventilation openings. The inner support plate 5 and the outer support plate 7 are movably connected through the holes opened on the surface and penetrate the manned frame 6. In the case of a large number of people, the ventilation openings can effectively reduce the stuffiness in the compartment, improve the overall strength and rigidity of the compartment, enabling it to better withstand various external forces and loads. The movable connection method facilitates operation during maintenance or component replacement, reducing the maintenance cost and difficulty. The buffer assembly includes a connecting plate 1101, a spring frame 1102 and a protective cylinder cover 1103. The bottom of the connecting plate 1101 is fixedly connected to the spring frame 1102, and the opposite connecting plates 1101 are fixedly connected to the protective cylinder cover 1103. The spring frame 1102 is sleeved with a protective cylinder cover 1103 that restricts displacement. During the operation of the elevator, especially during start-stop or when encountering impacts, the spring frame 1102 cooperates with the internal hydraulic damper to absorb and reduce vibrations and impact forces, providing a smoother and more comfortable riding experience for passengers. The protective cylinder cover 1103 can prevent dust, moisture, etc. from entering the spring frame, reducing the corrosion and wear of the spring and ensuring its stable performance. A guide sleeve is provided inside the protective cylinder cover 1103 to enable the telescopic movement of the spring to proceed along a predetermined direction, improving the consistency and reliability of the buffer effect.
[0032] When working, the operator enters the manned frame 6 through the assembly groove 15 opened on the front surface of the box cover 1. The operator stands on the low-speed airbag 4. When there is a fire, the smoke generated by the flame will be detected by the smoke detector, and the smoke detector will automatically control the water spray faucet 10 to spray the fire-fighting liquid in the water tank 2 to extinguish the fire. At the same time, it will notify the relevant personnel to rescue the operator. At the same time, the excess smoke will pass through the holes opened on the upper surface of the manned frame 6 and the cooperation of the negative pressure fan 3 and the Y-shaped ventilation pipe 13 to extract the smoke out of the elevator car body and into the elevator shaft. If the elevator suddenly drops, the outer support plate 7 and the inner support plate 5 surrounding the manned frame 6 will protect the manned frame 6 when it falls. At the same time, due to stall, the control chip in the airbag will open the low-speed airbag 4 and the vertical airbag 8 to protect the operator. The connecting plate 1101 at the bottom will drive the spring frame 1102 in the protection cylinder cover 1103 to buffer the impact force between the spring frame 1102 fixedly connected to the upper connecting plate 1101. Finally, the operator can wait for rescue.
[0033] Through the above steps, by adding the inner support plate 5, the outer support plate 7, the water tank 2 and the buffer assembly, the overall rigidity and load-bearing capacity of the car body can be significantly improved, making it more capable of withstanding various external forces and loads, and enhancing the riding comfort of passengers. The water tank 2 extinguishes the fire through the smoke detector and the water spray faucet 10. When the elevator suddenly stops, fails to fall or is accidentally collided, the buffer assembly can absorb and slow down the huge impact force and reduce the damage to the car body and passengers, so as to solve the problems of poor stability, limited buffering performance and poor fire prevention performance of the traditional car body protection structure for elevators.
[0034] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
