Description

Technical Field

[0002] With the development of technology, people's lives have gradually improved. Many old residential areas did not have elevators installed before, which made it difficult for people with mobility issues to go up and down the stairs. Therefore, many families have installed stairwell mobility aids to facilitate the movement of people up and down the stairs.

[0003] However, the stairwell mobility aids currently on the market have the following drawbacks:

[0004] 1. The power mechanism is cumbersome and lacks a self-locking function. For example, if the motor fails and loses power, the equipment and users may fall along the track.

[0005] 2. The distribution of the rollers providing anti-rollover force is unreasonable, with only two rollers on both the wall-side and pedestrian-side. Since the wall-side rollers provide the primary anti-rollover force, their number should obviously be greater than the number of pedestrian-side rollers for a more reasonable solution.

[0061] The following description, in conjunction with the accompanying drawings of specific embodiments of the present invention, will provide a clear and complete illustration of exemplary solutions. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art.

[0062] like Figure 1 and Figure 2 As shown, the stairwell mobility aid in this embodiment includes a base and a main unit. The base includes a track assembly and a foot assembly. The track assembly is fixed to the staircase on the wall side by multiple foot assemblies. The main unit includes a shell, a frame assembly, a power assembly, a pedal assembly, a limiting assembly, an electronic control assembly, and a handrail assembly. The shell is located directly above the track assembly to avoid occupying too much lateral space, making it more suitable for narrow stairwells and offering good versatility. The frame assembly is fixed to the shell. The power assembly is fixedly installed on the inner wall of the frame assembly. The pedal assembly is rotatably fixed to the inner wall of the frame assembly on the person-facing side. The limiting assembly is located on the lower part of the outer wall of the frame assembly. The electronic control assembly is fixed to the inner wall of the frame assembly. The handrail assembly is installed on the upper part of the outer wall of the frame assembly on the wall side.

[0063] like Figures 3 to 5 As shown, the track assembly includes a track, a helical rack 2, and a track end cap 108. Preferably, the track is an alloy track, and the helical rack 2 and track end cap 108 are made of nylon. The track is fixed to the stairs by a foot assembly. The track includes a track body 101, with a rack groove 102 and a gear groove 103 in the middle. The helical rack 2 is fixed in the rack groove 102 by T-bolts, with the tooth surface of the helical rack 2 facing the wall to prevent dust or other debris from falling in, improving operational stability and extending service life. The gear groove 103 allows collected dust to be discharged from the bottom by gravity. Two weight-reducing cable routing grooves 104 are provided on each side of the track body 101, which not only reduces the weight of the entire track and achieves lightweighting, but also allows for the arrangement of wires, preventing exposed wires from being messy and affecting aesthetics. An anti-tipping arm 105 is provided on the upper part of the track body 101 outside the weight-reducing cable routing groove 104 to provide anti-tipping function. A fixing groove 106 is provided at the lower part of the track body 101 outside the weight-reducing cable tray 104 for fixing the foot assembly. A guide rail 107 is provided on the track body 101 above the weight-reducing cable tray 104. The upper and lower ends of the track body 101 are fixedly connected to the track end cover 108 by tightening bolts. Here, the track provides support, guidance and anti-tipping functions for the operation of the main unit, and has a good guiding effect. The helical rack 2 and the gear 604 of the power component form a power system. The track end cover 108 can cover the exposed sharp corners of the track to prevent pedestrians from being scratched and to improve the appearance. The alloy track of this embodiment has high strength and integrates functions such as load-bearing, guidance, anti-tipping, sewage discharge and helical rack fixing, and has multiple uses; it is manufactured in one piece, which reduces costs.

[0064] like Figure 6 As shown, the anchor assembly includes a base plate 301, two middle plates 302, and a top plate 303. The base plate 301 is a thick steel plate, while the middle plates 302 and the top plate 303 are bent pieces of medium-thick steel plates. The base plate 301 is fixed to the horizontal surface of the stair treads with bolts, and the anchor assembly can be installed on each stair tread. The two middle plates 302 are fixed to the base plate 301 at intervals with bolts. The lower end of the top plate 303 is hinged to the middle plates 302, and the upper end of the top plate 303 is fixedly connected to the fixing groove 106 with T-bolts. The anchor assembly can fix the track assembly on the slope of the steps and can adapt to stairs with different slopes.

[0065] like Figure 7 and Figure 8As shown, the outer shell is a pentagonal box with openings at the top, bottom, and wall side, including a front shell 401, a rear upper shell 402, a rear lower shell 403, and an outer shell 404. The rear upper shell 402 and the rear lower shell 403 are fixedly connected by bolts, and the outer shell 404 is fixedly connected to the front shell 401, the rear upper shell 402, and the rear lower shell 403 by bolts. A brush 405 is fixed to the lower end of the rear lower shell 403 and the front shell 401 by bolts. The brush 405 cleans the dust on the guide rail 107 and the upper surface of the helical rack 2, and then the dust falls into the gear groove 103. Infrared sensor 406, emergency stop switch 407, and alarm light 408 are installed on the upper rear shell 402 and lower rear shell 403. Infrared sensor 406 is used to detect whether someone is approaching, so as to wake up the electronic components and put the equipment into standby mode. Alarm light 408 is used for overload or overvoltage alarm. Infrared sensor 406, hole plug 409, and lighting light 410 are installed on the front shell 401. Opening hole plug 409 facilitates operation of circuit breaker 911.

[0066] like Figures 9 to 11 As shown, the frame assembly includes a first main board 501 near the wall, a second main board 502 near the person, and a top baffle 503, forming a cage structure; the first main board 501 and the second main board 502 are spaced a certain distance apart and are fixedly connected to the front shell 401, the upper rear shell 402, and the lower rear shell 403 by seven connectors 508; the second main board 502 is fixed to the inner wall of the outer shell 404 by bolts. The upper part of the inner wall of the first main board 501 and the second main board 502 are fixedly connected by three upper connecting brackets 504, and the lower part of the inner wall is fixedly connected by two lower connecting brackets 505. Each lower connecting bracket 505 has a pair of guide wheels 506 mounted on its lower end via a guide wheel shaft. The guide wheels 506 are matched and set on the guide rail 107. The top baffle 503 is fixedly installed on the top of the first main board 501 and the second main board 502 by bolts. A top pad 507 is adhered to the upper surface of the top baffle 503, on which personal belongings can be placed. The frame assembly is used to fix the power assembly, limit assembly, pedal assembly, armrest assembly, electronic control assembly, outer shell, and seat assembly. This cage-like frame structure and the design of the connecting brackets can precisely control the distance between the two main boards and maintain the frame from deformation under load. The lower connecting brackets 505 can accurately control the distance and strength of the guide wheels 506, ensuring that the guide wheels 506 fit tightly against the guide rail 107 and operate stably without shaking.

[0067] like Figure 12As shown, the power assembly includes a motor 601, a reducer 602, a damping plate 603, and a gear 604. Preferably, the reducer 602 is a worm gear reducer with a self-locking ratio, the motor 601 is a DC servo motor, the gear 604 is a helical gear, and the damping plate 603 is a nylon plate adapted to the mounting holes of the reducer 602. The output shaft of the motor 601 is bolted to the input hole of the reducer 602, and the end of the output shaft of the reducer 602 is connected to the gear 604 via a key. The two sides of the reducer 602 are respectively fixed to the inner walls of the first main plate 501 and the second main plate 502 by the damping plates 603. The damping plates 603 greatly block the vibration and noise transmission of the power assembly. The high-speed, low-torque forward and reverse rotation of the motor 601's main shaft is converted into low-speed, high-torque forward and reverse rotation of the gear 604 by the reducer 602. By meshing the gear 604 with the helical rack 2, the main unit is controlled to run only along the length of the track. Furthermore, when the motor 601 is not providing power, the reducer 602 has a self-locking effect, greatly improving safety. Compared to the scheme where the pinion 604 drives the gear 604, the power assembly in this embodiment uses only one gear 604, shortening the transmission chain, using fewer parts, and reducing costs.

[0068] like Figure 13 As shown, the pedal assembly includes a pedal base 701, a pedal 702, a reversing arm 703, a push rod 704, and a push rod base 705. The pedal base 701 and the reversing arm 703 penetrate the second main board 502 and the outer shell 404. The pedal base 701 is fixed to the inner wall of the second main board 502 by bolts. The outer end of the reversing arm 703 is fixedly connected to the pedal 702 by bolts. The middle of the reversing arm 703 is hinged to the pedal base 701 via a pedal shaft. The inner end of the reversing arm 703 is connected to the head of the push rod 704 via a push rod shaft. The push rod base 705 is fixed to the inner wall of the second main board 502 by bolts and is hinged to the tail of the push rod 704. A tightening bolt 706 is provided on the upper surface of the inner end of the reversing arm 703. The pedal assembly converts the linear extension and retraction of the push rod 704 into the opening and closing action of the pedal 702, realizing the opening and closing of the pedal 702. When the tightening bolt 706 abuts against the second main board 502, the tightening bolt 706 and the reversing arm 703 are under force together. At this time, the push rod 704 is not under force. By lengthening the lateral force arm of the push rod 704, the pedal assembly reduces the thrust requirement of the push rod 704, which can significantly improve the service life of the push rod 704.

[0069] like Figure 14As shown, the limiting assembly includes a large limiting assembly and a small limiting assembly. The large limiting assembly includes a T-shaped limiting plate 801, an M-shaped limiting plate 802, and five first bolt roller bearings 803. The small limiting assembly includes two C-shaped limiting plates 804 and two second bolt roller bearings 805. The T-shaped limiting plate 801, M-shaped limiting plate 802, and C-shaped limiting plate 804 are thick steel plate parts, while the first bolt roller bearings 803 and second bolt roller bearings 805 are standard parts. The T-shaped limiting plate 801 is fixed to the lower part of the outer wall of the first main plate 501 by bolts. The M-shaped limiting plate 802 is fixedly connected to the T-shaped limiting plate 801 by bolts. Five first bolt roller bearings 803 are arranged side by side at the lower end of the M-shaped limiting plate 802, which are tangent to the lower surface of the anti-rollover arm 105 and roll up and down along the lower surface of the anti-rollover arm 105. Two C-shaped limiting plates 804 are bolted side-by-side to the lower outer wall of the second main unit 502. Each C-shaped limiting plate 804 has a second bolt roller bearing 805 tangential to the lower surface of the anti-tipping arm 105 at its lower end. Because a person stands on the step 702, the first bolt roller bearing 803 on the wall side provides the main anti-tipping force; therefore, five first bolt roller bearings 803 and two second bolt roller bearings 805 are provided. The limiting assembly prevents the main unit from tilting inwards or outwards towards the wall, and also prevents it from tilting up and down along the stairs.

[0070] like Figure 15As shown, the electronic control components include a battery 901, a controller 902, a motor driver 903, a positioning module, and an automatic charging module. The controller 902 receives signals from switches and sensors, driving the motor 601, push rod 704, alarm light 408, and lighting light 411, etc., to achieve coordinated operation between the components. The battery 901, controller 902, and motor driver 903 are fixed to the inner wall of the second main board 502 by bolts, and can be rationally arranged according to the space between the first main board 501 and the second main board 502. The positioning module includes a positioning magnet 904, a Hall switch 905, and a Hall bracket 906. The positioning magnet 904 is a conventional magnet strip, the Hall switch 905 is a standard part, and the Hall bracket 906 is a thin plate bending part. The positioning magnet 904 is fixed to the upper surface of the anti-tipping arm 105 on the wall side of the upper and lower ends of the track body 101 by self-tapping screws. The Hall bracket 906 is fixed to the upper and lower protruding parts of the M-shaped limit plate 802 by bolts. The Hall switch 905 is installed through the upper part of the Hall bracket 906, and the sensing surface of the Hall switch 905 is parallel to the positioning magnet 904, with a distance of a few millimeters, to ensure that the Hall switch 905 can accurately sense the positioning magnet 904. The automatic charging module includes a fixing block 907 and positive and negative collector plates 908. The fixing block 907 is made of nylon and is fixed to the upper and lower ends of the track body 101 on the wall side by bolts. The fixing block 907 is provided with a first terminal 909. The positive and negative collector plates 908 are fixed to the upper and lower protruding parts of the M-shaped limiting plate 802 by bolts.
