DETAILED DESCRIPTION

[0021] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0022] like Figure 1 — Figure 4 and Figure 7 As shown, an automatic elevator includes a ladder cabinet 1 for people to ride in, the ladder cabinet 1 is hoisted under a moving device 2, the moving device 2 is mounted on a moving platform 3, the moving platform 3 is hoisted on the top of the stairwell by a hanger 4 and is erected along the top of the stairwell to the roof; a side sliding device 5 is provided at the lower part of the side of the ladder cabinet 1 close to the stair handrail, the side sliding device 5 is carried on an auxiliary rod 6, the auxiliary rod 6 is erected at the lower part of the stair handrail and extends into the stairwell space, and the auxiliary rod 6 also winds to the top floor along the stair handrail.

[0023] The mobile device 2 includes a motor 21 with output shafts 211 at both ends, that is, a forward and reverse dual output shaft motor 21. The output shaft 211 of the motor 21 is mounted on the mobile platform 3, and a rolling wheel 212 is fixed to the output shaft 211 of the motor 21. The mobile device 2 can move relative to the mobile platform 3. A gear 213 is also fixed to the output shaft 211 on one side of the motor 21. The gear 213 is on the output shaft 211 between the rolling wheel 212 and the main body of the motor 21.

[0024] The mobile platform 3 includes two parallel track tubes 31. The ladder cabinet 1 is suspended at the lower part of the motor 21 in the mobile device 2 and is located below the two track tubes 31. The track tube 31 enables the output shaft 211 of the power supply machine 21 to exert force and roll. The ladder cabinet 1 is suspended at the lower part of the motor 21 and can stabilize the body of the motor 21 to a certain extent; a row of gear bars 32 are also fixed on one side of the track tube 31. The gear bars 32 are arranged parallel to the track tube 31 and meander to the roof. The gear bars 32 are meshed with the gear 213 on the output shaft 211 of the motor 21.

[0025] The side sliding device 5 is equivalent to another stable point of the elevator cabinet 1. Combined with the design of the two track tubes 31, a three-point automatic elevator is formed, and the elevator cabinet 1 remains stable during operation. The side sliding device 5 includes a top wheel 51 overlapped on the auxiliary rod 6, and also includes a bottom wheel 52 with a top abutting against the lower part of the auxiliary rod 6. The top wheel 51 and the bottom wheel 52 clamp the auxiliary rod 6 to slide, and the top wheel 51 and the bottom wheel 52 are both fixed on the side sliding device 5.

[0026] For the power supply of the motor 21, a sliding pick-up method is adopted, and the power required by the motor 21 is always supplied when the motor 21 is in motion. The specific method is: the automatic elevator also includes a power supply group 7, which is composed of a circuit slide 71 and a pick-up arm 72. The circuit slide 71 is erected on one side of the hanger 4, and the pick-up arm 72 is located on the moving device 2 and abuts against the circuit slide 71. The pick-up arm 72 slides relative to the circuit slide 71. Of course, the circuit slice is arranged in the circuit slide 71, and power supply is formed only under the action of the pick-up arm 72. In order to better protect safety, generally, each slide of the circuit slide 71 should be wrapped with an insulating rubber sleeve, which protects the circuit from being exposed while not delaying the sliding of the pick-up arm 72.

[0027] Conventionally, the ladder cabinet 1 has an access door 8 on the inner side facing the stairs (i.e., the access door 8 is provided on the side close to the stairs, so that there is no visual difference with the stairs), and a seat is provided inside the ladder cabinet 1 for easy sitting. The ladder cabinet 1 has a relatively slow speed when in operation, so that it will not scare the elderly. At the same time, the ladder cabinet 1 is close to the stairs, so that it will not give people a serious sense of suspension, and it is also convenient for users to get on and off the ladder cabinet 1.

[0028] The utility model has a general electric controller, which is mainly responsible for the on-off of the circuit. A blocker 9 is fixed on the other side of the track tube 31 relative to the gear bar 32. The blocker 9 has a movable plate 91 that is higher than the track plane of the track tube 31. The movable plate 91 is used to move the moving device 2 that is moving back and forth. The device for moving the movable plate 91 is a rolling wheel 212 that moves on the track tube 31 or a dial plate (not shown in the figure) extending from the moving device 2. When the rolling wheel 212 moves the movable plate 91, it is fed back to the electric controller, prompting the moving device 2 and the ladder cabinet 1 to reach the specified position, and judging whether to continue to move or stop; generally, the blocker 9 is set to the corresponding floor stop position, so that the ladder cabinet 1 is exactly on the top step of the floor. After the door 8 is opened, the ladder cabinet 1 can be directly accessed, which is convenient for the elderly to travel.

[0029] The method of using the automatic elevator is as follows: the user presses the staircase button, the elevator cabinet 1 runs to the user's floor, and after the user gets on the elevator cabinet 1, the elevator cabinet 1 runs to the floor required by the user; when not in use, the elevator cabinet 1 runs to the first floor or the top floor, in a less obstructed space.

[0030] like Figure 5As shown, the track tube 31 winds upward, and the tracks between the upper and lower floors are parallel to each other. This design ensures the stability of the operation of the motor 21 and avoids the influence of adverse factors caused by the angle deviation of the track tube 31.

[0031] like Figure 6 As shown, the track tube 31 and the auxiliary rod 6 are extended to the top floor and are bent accordingly at the turning position of the stairs. When looking down at the track tube 31 and the auxiliary rod 6, no matter at which bending position, the overlap points of the two output shafts 211 and the track tube 31, and the overlap points of the top wheel 51 and the auxiliary rod 6 are all concentrated at one point, thus ensuring the stability of the ladder cabinet 1 during travel.

[0032] In addition to the equipment, the operation of the automatic elevator can also be developed and applied with supporting software in actual use. For example, a monitoring and alarm device is set in the stairwell. Once someone is in the stairwell, an alarm will be sounded or the operation of the elevator cabinet 1 will be suspended; an emergency button is set on the elevator cabinet 1. Once an emergency occurs, the emergency button is pressed to emergency brake the elevator cabinet 1. Since the automatic elevator is mainly used in multi-story buildings where many elderly people live, in order to ensure the safety of the automatic elevator and the safety of people who accidentally break into the corridor, three automatic control steps can be added:

[0033] 1) Before the automatic elevator in the corridor starts to operate, the infrared device needs to be turned on to sense the human body and make sure that there is no one in the corridor before starting the second step;

[0034] 2) Check whether the elevator is overloaded. If it is overloaded, the alarm device will sound and a voice reminder will be given. If it is not corrected within half a minute, the starting power will be turned off. If it is corrected, the third step will be started;

[0035] 3) After the above two steps are completed, the door lock of the residents' main door on the floor is automatically closed (the magnetic lock that is opened and closed under software control), and the automatic elevator starts to operate normally. It runs to the door outside the floor where the elevator cabinet is called. The caller manually unlocks the door lock and enters the elevator cabinet to the floor he wants to go to. After the caller gets off the elevator cabinet, he enters the door and closes it. The elevator completes this operation and returns to the top-floor parking space. The software controls all the magnetic locks to unlock.

[0036] In terms of weight limit, it is generally set not to exceed 250KG and is limited to two people. This greatly reduces the strength requirements of the automatic elevator, makes the choice of manufacturing materials more extensive, and reduces the manufacturing cost a lot. At the same time, the two-person load limit also guarantees safety to a certain extent and avoids mechanical damage to the automatic elevator that may be caused by excessive weight.

[0037] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
