[0002] A home elevator is an elevator installed in a private residence and used only by a single family member. The application scenarios of home elevators are mainly rural areas, urban villages, and villa areas.

[0003] The size of home elevators is relatively small, and the height difference is usually around 10 meters.

[0004] When an elevator breaks down, the car will pause. Since the pause location is uncertain and there is only a single exit on each floor, when an elevator breaks down, especially when the car door is misaligned with the floor elevator door, it will be impossible to escape. An escape hatch is usually set on the top of the car. It is very difficult to climb out of the car through this top-mounted escape hatch. After escaping from the top escape hatch, it is also difficult to climb to the floor elevator door on the upper floor, and falling incidents may occur easily.

[0005] To this end, we have designed a home elevator door specifically for small home elevators that is easy to escape from the bottom and easy to get out of trouble on your own. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] See also Figures 1 to 7 and Fig.14A household elevator door that is easy to escape from trouble by oneself is shown, comprising a lower box body 2, an upper box body 1 and a flexible rolling door 3, wherein a reel 441 is rotatably installed inside the upper box body 1, and a driving motor 4 that drives the reel 441 to rotate is installed on the side of the upper box body 1, one end of the flexible rolling door 3 is wound on the reel, and a sliding rod structure 5 is fixed to the other end of the flexible rolling door 3, and a through groove 31 is provided on the surface of the flexible rolling door 3, and a guide rod structure 6 is installed between the upper box body 1 and the lower box body 2, and the guide rod structure 6 can be disconnected, and two guide rod structures 6 are provided in parallel, and the sliding rod structure 5 slides along the guide rod structure 6 After being taken out, the flexible rolling door 3 is unwound from the reel, and the lower end of the flexible rolling door 3 passes through the lower part of the elevator car. The escapee steps on the through groove 31 and descends along the flexible rolling door 3 to escape; two side rods 7 are installed between the upper box body 1 and the lower box body 2, and the sliding rod structure 5 slides along the side rods 7. The inner side of the side rod 7 is provided with a sliding groove 71 that matches the sliding rod structure 5, and a sliding outlet 72 is provided on the side of the sliding groove 71 near the bottom. When the guide rod structure 6 is disconnected, the disconnection position corresponds to the sliding outlet 72, and the sliding rod structure 5 slides out from the sliding outlet 72.

[0043] In the above technical solution, the drive motor 4 is a motor that can be manually operated in the case of power failure, and the unwinding chain is operated to hang down into the car. An equipment box can be installed on the top of the elevator car to store the manual chain.

[0044] The bottom plate of the car is modified by using Figure 6 and Fig.14 A bottom plate 991 is provided with a stepped groove 992, and a rotatably openable cover plate 993 is rotatably installed in the stepped groove 992.

[0045] When a car failure occurs, the slide rod structure 5 can be removed from the disconnected position by disconnecting the lower end of the guide rod structure 6, and then the cover plate 993 is opened to actively pull the flexible rolling door 3 downward until the flexible rolling door 3 is completely pulled out.

[0046] The flexible rolling door 3 is lowered from the step groove 992, and then the trapped persons in the car can escape along the flexible rolling door.

[0047] When the car is at the bottom of the elevator shaft and fails, you can simply open the door to escape.

[0048] It should be noted that an active power-off switch needs to be installed in the elevator car to cut off the power of the elevator in the car to avoid the elevator resuming operation during the escape process, making the escape safer.

[0049] It should be noted that the weight of the slide bar structure 5 needs to be greater than 10 kg, so that when the driving motor 4 releases the flexible rolling door 3, the slide bar structure 5 can straighten the pulled-out part of the flexible rolling door 3 under the action of gravity.

[0050] See also Figure 8 As shown, the flexible rolling door 3 includes a middle layer 301 and a surface layer 302 . The surface layer 302 is provided with two layers, which are respectively located on both sides of the middle layer 301 . The middle layer 301 is PVC soft glass, and the surface layer 302 is nylon cloth.

[0051] In the above technical solution, PVC soft glass is used as the middle layer 301, and nylon cloth 302 is used as the surface layer.

[0052] PVC soft glass can be shaped and deformed and provide a certain degree of protection, and nylon cloth 302 has strong tensile resistance.

[0053] When people inside escape, the flexible rolling door 3 composed of the middle layer 301 and the surface layer 302 can meet the load-bearing requirements.

[0054] See also Figure 3 , Figure 4 and Figure 7 As shown, the guide rod structure 6 includes a lower guide rod 601 and an upper guide rod 602, the upper end of the upper guide rod 602 is fixed to the upper box body 1, and the lower part of the lower guide rod 601 is processed with a threaded portion 611, which is threadedly matched with the lower box body 2 through the threaded portion 611, and a sleeve 603 is provided at the upper end of the lower guide rod 601. After the lower guide rod 601 is screwed up, the upper guide rod 602 is inserted into the sleeve 603, and the sliding rod structure 5 is matched between the upper guide rods 602 on both sides. When the lower guide rod 601 slides down, the sliding rod structure 5 slides out from the bottom of the upper guide rod 602.

[0055] In the above technical solution, the upper guide rod 602 is normally used for sliding guidance of the slide rod structure 5. When the elevator fails and is stuck in mid-air, the lower guide rod 601 can be rotated downward to separate the socket 603 from the upper guide rod 602. Then the slide rod structure 5 can be taken out from the separation position, and the flexible rolling door 3 can be pulled out for use as an escape staircase.

[0056] See also Figure 3 and Fig. 9As shown, through grooves are provided on both sides of the lower box body 2, and locking plates 21 are slidably matched in the through grooves. A roller 22 is provided at the end of the locking plate 21 located in the lower box body 2, and the roller 22 is rotatably matched with the locking plate 21. A connecting plate 23 is provided at the lower part of the locking plate 21. A guide rod 24 is provided at the inner wall of the lower box body 2. The guide rod 24 passes through the connecting plate 23 horizontally and then cooperates with a limiting nut 25. A spring 26 is provided on the guide rod 24, and the spring 26 acts between the lower box body 2 and the connecting plate 23. Locking plates 27 are installed on the shaft walls on both sides of the elevator shaft, and retaining teeth 28 are evenly distributed on the plate surface of the locking plate 27. The spacing between the upper and lower retaining teeth 28 is 2 to 4 times the thickness of the locking plate 21. When the locking plates 21 on both sides slide out to the limit position along the through slot, the vertical displacement of the locking plate 21 is limited by the retaining teeth 28. A rotating seat 29 is provided at the inner top position of the lower box body 2. A rotating plate 210 is cooperated with the rotating seat 29. The rotating plate 210 acts on the roller 22. The lower end of the lower guide rod 601 corresponds to the rotating plate 210. After the lower guide rod 601 rotates downward, it pushes the rotating plate 210 to rotate along the rotating seat 29. The rotating plate 210 acts on the roller 22, so that the locking plate 21 slides out along the through slot.

[0057] In the above technical scheme, an active locking effect can be achieved. When the lower guide rod 601 is screwed down, the lower end of the lower guide rod 601 will act on the rotating plate 210, so that the rotating plate 210 pushes the locking plate 21 to slide out. After sliding out, the locking plate 21 is limited by the blocking teeth 28 to avoid the situation where the car descends during the escape process.

[0058] That is to say, if one wants to escape from the bottom of the car, the lower guide rod 601 must be rotated downward. The lower guide rod 601 needs to be rotated downward to a sufficient depth to meet the sliding out requirement of the slide bar structure 5. The height to which the lower guide rod 601 is lowered can complete the ejection of the locking plate 21.

[0059] The locking plates 21 on the left and right sides are staggered in height, and the staggered spacing is greater than the thickness of one of the retaining teeth 28 .

[0060] This technical solution is mainly for dealing with the situation where the locking plate 21 and the latching tooth 28 are opposite to each other. When the lower guide rod 601 is rotated downward until the locking plate 21 and the latching tooth 28 are pressed against each other, it is necessary to ensure that the space between the plug sleeve 603 and the upper guide rod 602 is sufficient for the slide rod structure 5 to slide out after the plug sleeve 603 moves downward.

[0061] The above technical solution can ensure that at least one latching tooth can be misaligned with the retaining tooth 28 .

[0062] See also Fig. 9As shown, a pressure block 233 is disposed inside the lower box body 2 , and the lower end surface of the pressure block 233 acts on the locking plate 21 .

[0063] The pressure block 233 is provided to increase the contact area with the locking plate 21 .

[0064] See also Figure 5 , Fig.10 , Fig.11 and Fig.12 As shown, the sliding rod structure 5 includes a sliding rod 501, a fixing groove 502 is arranged at the top of the sliding rod 501, and the lower end of the flexible rolling door 3 is inserted into the fixing groove 502 and fixed therein, and through holes 503 are arranged at the top of the sliding rod 501 on both sides of the fixing groove 502, and the upper guide rod 602 passes through the through holes 503, and sliders 504 are arranged at both ends of the sliding rod 501, and the sliders 504 cooperate with the sliding groove 71, and the sliders 504 can slide out from the sliding outlet 72.

[0065] In the above technical solution, the flexible rolling door 3 and the fixing groove 502 are fixed by bolts.

[0066] The cooperation between the slider 504 and the slide groove 71 can play a guiding role.

[0067] See also Figure 3 , Figure 5 , Fig.10 , Fig.11 and Fig.12 As shown, a first through hole 511 is provided on the end surface of the slider 504, and a first slide groove 512 is provided at the rear side of the slide rod 501 near the two ends. A directional rod 513 is installed in the first slide groove 512, and a lever 514 is matched with the directional rod 513. The lever 514 has a locking rod 515 matched with the first through hole 511. A first spring 516 is provided on the directional rod 513. Under the action of the first spring 516, the locking rod 515 passes through the first through hole 511. A spring 516 is provided on the outer wall of the slide groove 71 to insert the locking rod 515. 15, a locking hole 771 is provided, an engine box 772 is installed on the outside of the side rod 7, a micro electric push rod 773 is installed in the engine box 772, the telescopic end of the micro electric push rod 773 is inserted into the locking hole 771, when the car is running, the micro electric push rod 773 retracts, so that the locking rod 515 pops out and then inserts into the locking hole 771, at this time the slide bar 501 is locked, when the car runs to the floor position, the micro electric push rod 773 is extended, so that the locking rod 515 is pushed out of the locking hole 771, at this time the slide bar 501 can slide along the slide groove 71.

[0068] In the above technical solution, when the elevator car is running normally, the locking rod 515 is inserted into the locking hole 771 to prevent the internal personnel from contacting the flexible rolling door during the movement of the car, thereby preventing the sliding rod 501 from sliding upward. It is ensured that during the operation of the elevator car, the part of the flexible rolling door 3 between the reel 441 and the sliding rod 501 is straightened.

[0069] Specifically, by programming the driving motor 4, when unwinding the flexible rolling door 3, the overtravel unwinding is performed, and then the rewinding is performed. When unwinding the overtravel, it can be ensured that the slide bar 501 slides down to the locking bar 515 and cooperates with the locking hole 771. The purpose of rewinding is to straighten the flexible rolling door 3 to ensure that it has sufficient protection capability.

[0070] The drive motor 4 is in a self-locking state after rewinding.

[0071] See also Figure 5 and Fig.12 As shown, the end of the locking rod 515 is a spherical end 555. When the micro electric push rod 773 is pushed out to the extreme position, a part of the spherical end 555 is located in the locking hole 771. As the driving motor 4 drives the roller to wind the flexible rolling door 3, when the slide rod 501 moves upward, the spherical end 555 is pressed into the slide rod 501 under the action of the groove wall of the slide groove 71.

[0072] In this technical solution, the end of the micro push rod 773 is located in the locking hole 771 to avoid intrusion into the slide groove 71.

[0073] The contact area between the spherical end 555 and the bottom of the slide groove 71 is relatively small. Considering the need to manually open the locking rod 515, the first spring 516 is a thin spring with a wire diameter of about 0.6 mm.

[0074] The use of a small first spring can also prevent the contact force between the spherical end 555 and the slide groove 71 from being too large, thereby preventing the slide bar 501 from being stuck in downward movement due to the excessive contact force.

[0075] See also Figure 2 As shown, a transition roller 442 is provided in the upper box body 1 , and the flexible rolling door 3 enters from the bottom opening of the upper box body 1 and transitions to the reel 441 through the transition roller 442 .

[0076] The setting of the transition roller 442 can roll up the flexible rolling door 3 more smoothly.
