Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a home elevator that facilitates escape from danger. Background Technology

[0002] Elevators are frequently used mechanical devices, but they are also among the most dangerous. Every year, many people are injured or killed due to elevator malfunctions. Therefore, enabling immediate evacuation when an elevator malfunctions has become a technological innovation. There are various types of evacuation elevators on the market, some of which are intelligent. However, such intelligent systems cannot actually free trapped people, thus failing to alleviate their anxiety and being inconvenient.

[0003] Therefore, to facilitate escape, Chinese patent CN212982191U describes an elevator for intelligent escape, which includes an exit, a telescopic ladder assembly, and an escape compartment at the top of the car. This allows trapped passengers to pass through the exit into the escape compartment and then exit through the elevator door on the upper floor in the event of a sudden elevator malfunction, thus avoiding prolonged waiting inside the car. This design is safe, reliable, and easy to implement. During normal elevator operation, the telescopic ladder can be stored in a mounting frame and fixed to the top of the car with a cover plate, without occupying internal car space, making it convenient and practical. While this patent does achieve the goal of facilitating escape, it still has certain shortcomings. Entering the escape compartment and exiting through the upper elevator door is extremely dangerous and impractical. A design based on common sense should be followed. In the event of an elevator accident or malfunction, one should remain calm inside the elevator until professional rescue personnel arrive. Therefore, the aforementioned patent poses a significant safety hazard.

[0004] In order to reduce safety hazards and facilitate escape from danger, a home elevator that facilitates escape from danger is proposed, thereby solving the problems of high safety hazards and inconvenience in the existing technology. Utility Model Content

Note that a sensor is located at the top of the elevator car; the motor will only start when the sensor's connection to the escape door cover is lost. Passengers can then climb the telescopic ladder to the top of the elevator car. Rescuers will then open the upper elevator door, and the trapped person can use a connecting rope to pull the ladder up. The ladder will then be manually extended again, secured step-by-step with the latches in the toolbox, and the protective plate will be flipped outwards to contact the elevator shaft surface. With the help of rescuers, the trapped person can then climb out using the telescopic ladder, facilitating escape. This method is more convenient as rescuers no longer need to carry the ladder separately and also allows them to easily descend into the shaft to inspect the elevator. Attached Figure Description

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. Example

[0027] Please see Figure 1-8 This utility model provides the following technical solution: a home elevator for easy escape, comprising a frame structure and an elevator car 10. The elevator car 10 is installed inside the frame structure. An escape structure for escaping when the elevator malfunctions is installed at the upper end of the elevator car 10. This escape structure includes an escape door cover 3, a power backup box 17, a telescopic motor 18, a lighting lamp 19, a protective plate 20, a telescopic ladder 21, and a tool box 22. The power backup box 17, the telescopic motor 18, the lighting lamp 19, the protective plate 20, and the tool box 22 are all installed on the top of the elevator car 10. The inner end of the protective plate 20 contacts the outer end face of the telescopic motor 18, and the telescopic motor 18 extends and retracts... The elevator car 10 is connected to the telescopic ladder 21. An opening is provided on the top of the elevator car 10. An escape door cover 3 is installed on the top of the inner side of the elevator car 10 via a hinge. A pin is provided on the lower end of the escape door cover 3 and the top of the inner side of the elevator car 10 to fix the escape door cover 3. Lighting lamps 19 are symmetrically distributed on the top of the elevator car 10. The power backup box 17 is connected to the telescopic motor 18 via a wire. A connecting rope is connected to the telescopic ladder surface at the outer end of the telescopic ladder 21. The length of the connecting rope is twice the height of the elevator car 10 and is coiled on the top surface of the elevator car 10. Each step of the telescopic ladder 21 has an opening. A pin is stored in the tool box 22.

[0028] The specific working principle of this implementation plan is as follows: First, it should be noted that, please refer to... Figure 4 and Figure 5As can be seen, a sensor is installed at the upper end of the elevator car 10 at the escape door cover 3. This sensor senses the status of the escape door cover 3. When the elevator malfunctions, an audio message begins playing inside the elevator car 10, reminding people inside to move away from the escape door cover 3 and instructing trapped individuals to open the latch connecting the escape door cover 3 to the elevator car 10. At this point, the sensor deactivates, and the telescopic motor 18 starts, driving the telescopic ladder 21 forward. Furthermore, the telescopic end of the telescopic motor 18 is movably connected to the telescopic ladder 21, allowing the ladder 21 to extend into the elevator car 10 for easy climbing. Additionally, the lighting 19 is turned on to allow people to see their surroundings. When people are climbing, a protective plate 20 prevents them from falling due to... There is a risk that the telescopic motor 18 may tilt due to gravity. At this time, all personnel should climb to the top of the elevator car 10. It is important to note that the rescue personnel must be on safe ground before proceeding. The trapped person should then pull the connecting rope to bring up the telescopic ladder 21. The telescopic ladder 21 should then be manually extended, and the tool box 22 should be opened. The pin should be inserted into the opening on the telescopic ladder 21 to secure it, making it easier for the trapped person to climb to the next floor elevator entrance for rescue. The telescopic ladder 21 also allows maintenance personnel to easily enter the top of the elevator car 10 for inspection without the need for rescue personnel to carry ladders or other tools. Even in the event of a power outage, the overall power supply of the elevator car will be maintained by the power in the backup power box 17.

[0029] Based on the above, please refer to the specific framework structure. Figure 1 and Figure 2 As can be seen, the frame structure includes carriage columns 1, lower crossbeams 2, and upper crossbeams 5; the lower crossbeams 2 are connected to the lower inner side of the two sets of carriage columns 1, and the carriage columns 1 and lower crossbeams 2 stabilize the elevator car 10. The bottom of the elevator car 10 is connected to the lower crossbeams 2, and the two sides are connected to the carriage columns 1. A set of anti-rope pulleys 6 is installed at the upper end of the upper crossbeam 5.
