When it runs to touch the point-moving limit wheel 43 of the upper limit remote control transmitter 35 on the upper positioning rod, the pedal 14 reaches the upper step 10 and stops rising, reaching the floor. As long as the user door or the elevator door on this floor is opened, the locator on the door will make the point-moving limit wheel 43 act, and the welcome elevator will automatically run to the position closest to the household. The welcome elevator goes up, the user enters, puts down the handrail, and presses the button by himself to make the welcome elevator run to the required floor, and can leave by lifting the handrail. It fully improves the convenience and efficiency of the user's travel.

[0033] The lower positioning rod is composed of a rack welded to an angle steel. Multiple positioning expansion bolts are respectively arranged on the inner side of the angle steel and on the stair wall of the positioning rod. The outer ends of the expansion screws are respectively connected and positioned with their corresponding inclined beak clamps, upper conduits, and holes on one side of the angle steel. The upper positioning plate is fixed to the upper floor, and the lower positioning plate is fixed to the lower floor to ensure that the positioning rod is vertical. The upper conduit is parallel to the lower guide rod, so that the upper positioning pulley and the reducer gear move smoothly on the upper conduit and the lower guide rod.

[0034] The contact rod 45 is arranged in the limiter 44 of the point-moving limit wheel 43. A point-moving transmitter 46 is arranged under the contact rod 45. The back of the point-moving transmitter 46 is provided with an adhesive tape 48. When the contact rod 45 presses the (upper) part of the transmitter, it forms a transmitter for the upper point-moving limit, which is arranged on the user door frame. When the contact rod 45 presses the (lower) part of the transmitter, it forms a transmitter for the lower point-moving limit, which is arranged on one side of the elevator door frame on this floor. Locators are arranged on both the user door and the elevator door for pressing the point-moving limit wheel of the point-moving limit transmitter 43 when the door is opened.

[0035] The up-and-down control system 36 includes one welcome remote control receiver installed inside the mobile lifting frame; three upper jog limit transmitters and three lower jog limit transmitters configured; one on each side wall of the upper and lower positioning rods, one on each side of the mobile lifting frame, and one upper limit remote control transmitter on the household door frame; one lower limit remote control transmitter on the elevator door frame of this floor; two relays 40, four high-power relays 41 (24V 100A single input and single output), six anti-backflow pipes, etc.

[0036] The limit remote control transmitter consists of an upper part jog limit wheel 43 of the limiter, a limiter 44; a contact rod 45; a jog transmitter 46; an adhesive 47 and a jog self-locking remote control transmitter.

[0037] When the contact rod 45 in the upper part of the limiter is placed at remote control transmitter A, it becomes the upper limit remote control transmitter; when the contact rod is placed at remote control transmitter B, it becomes the lower limit remote control transmitter. Pressing A once is up, and pressing A again is stop; pressing B once is down, and pressing B again is stop.

[0038] An automatic welcome elevator in the present application uses a positioning rod and an inclined-angle duckbill clip to connect the upper conduit 8, and a lower inclined-angle duckbill clip to connect the lower positioning rod with a rack to form a guide rail mechanism. Positioning expansion bolts 30 are provided on the inner sides of the angle irons of the positioning rod, the upper conduit, and the lower positioning rod and the staircase wall 27, which improves the firmness of the guide rail mechanism. The flexible connection method of using the inclined-angle duckbill clip to connect the guide rail and the positioning rod not only facilitates the up-and-down adjustment of the guide rail but also can be used in corridors with different slopes, improving its versatility. A folding zipper is provided on the moving lifting frame and the left pedal to increase the load-bearing capacity and safety of the pedal. When not in use, the folding button on the crossbar of the folding frame can be pressed, and the folding rod 21 acts to fold and retract the pedal 14 through the folding zipper, without affecting the up-and-down movement of others. A point-motion limit type transmitter is provided on the user's door frame and the elevator door frame. As long as the user's door or the elevator door on this floor is opened, the point-motion limit type transmitter will be triggered, causing the remote control receiver 39 to activate the high-power relay 41 and the folding relay 40, so that the welcome elevator can lower the pedal and reach the position closest to the user to welcome the user, facilitating the user to quickly board the automatic welcome elevator. After stepping on the pedal, the folding handrail frame is pulled down, and the folding handrail rods at both ends of the handrail frame protect the user or the wheelchair, ensuring the safety of the user while quickly going up and down the stairs. The low-power remote control receiver 39 plus the anti-backflow pipe 42 drive the high-power worm and worm gear reduction motor 11 to rotate forward and backward, driving the welcome elevator up and down, and the control method is simpler and the cost is lower. With the folding handrail rod, pressing the button switch in the upper handrail rod can make the automatic welcome elevator go up and down. It not only has the function of manual control for carrying people. The worm and worm gear reduction motor drives the winch to wind and unwind the cable, and the gears, the anti-disengagement wheel with bearings, and the pressure pulley improve the stability of the automatic welcome elevator going up and down and reduce the friction. It ensures the safe operation of the automatic welcome elevator, and at the same time can also meet the use of wheelchair passengers. The structure is simple and the cost is low, making home care safer and more convenient and facilitating its popularization.
