Description

Technical Field

[0001] The present invention relates to the technical field of stair-going and stair-going assisting devices, and in particular to a lifting assembly and a stairway walking device. Background Art

[0002] Many old residential areas still have traditional staircases, and due to the outdated facilities in these residential areas, the high cost of installing elevators and the difficulty of approval, elevators are not installed. For the elderly living in these residential areas, going up and down the stairs becomes extremely difficult. In order to solve the problem of the elderly going up and down the stairs, corridor walkers came into being.

[0003] Usually, a corridor walker includes a control component, a guide rail component installed on the corridor, a lifting component arranged on the guide rail component, and a driving component installed in the guide rail component for driving the lifting component to perform reciprocating linear motion along the guide rail component.

[0072] like Figure 2-13 As shown, the present invention provides a lifting assembly, including a body 100, a pedal 200, a first driving mechanism (not shown in the drawings), an armrest mechanism, a winding mechanism, a safety belt 510, a first locking mechanism and a second locking mechanism.

[0073] The body 100 is slidably connected to the guide rail assembly of the corridor walker. The pedal 200 is arranged at the bottom of the body 100, and the first end of the pedal 200 is hinged to the body 100, and the second end can swing back and forth between the first working position A and the second working position A around its hinge center line. Specifically, when the pedal 200 is in the first working position A, the pedal 200 is kept flush with the body 100 to achieve the purpose of reducing the space temporarily used by the lifting assembly, thereby facilitating pedestrians to pass through the corridor, thereby achieving the purpose of not affecting the normal use of the corridor; when the pedal 200 is in the second working position A, the pedal 200 is at an angle α with the horizontal plane, wherein 0°≤α≤10°, preferably, α=0°, that is, the pedal 200 remains horizontal, so that people can stand on the pedal 200 and move with the lifting assembly.

[0074] The first driving mechanism is disposed in the machine body 100, and is used to drive the pedal 200 to swing back and forth between the first working position A and the second working position A. Specifically, the first driving mechanism includes a motor, and a power output shaft of the motor is drivingly connected to a power input end of the pedal 200, for example: the power output shaft of the motor is fixedly connected to the pedal 200, and the power output shaft of the motor is drivingly connected to the pedal 200 through a gear structure or a transmission belt structure, and the motor is used to drive the pedal 200 to swing back and forth between the first working position A and the second working position A at a preset angle β.

[0075] The armrest mechanism includes an armrest A310 and an armrest B320, which are respectively installed on both sides of the top of the machine body 100, and the first ends of the armrests A310 and B320 are hinged to the machine body 100, and the second ends can reciprocate linearly around their own axis lines between the first working position B and the second working position B. Specifically, when the armrests A310 and B320 are located at the first working position B, the armrests A310 and B320 remain parallel to the machine body 100, thereby achieving the purpose of reducing the space temporarily used by the lifting assembly; when the armrests A310 and B320 are located at the second working position B, the armrests A310 and B320 form an angle γ with the bottom end of the machine body 100, wherein 95°≥γ≥90°, thereby achieving the purpose of facilitating people to hold the armrests. The second ends of the armrests A310 and B320 are both equipped with control buttons, which are used to control the driving assembly to drive the lifting assembly to rise or fall.

[0076] The reeling mechanism rotates the second end of the armrest A310. The first end of the safety belt 510 is fixedly connected to the reeling mechanism, and the second end is provided with a lock buckle 520. Specifically, the reeling assembly includes a reel 410 and a scroll torsion spring (not shown in the drawings), the reel 410 is rotatably installed in the second end of the armrest A310, the two ends of the scroll torsion spring are respectively connected to the reel 410 and the armrest A310, and in a natural state, the scroll torsion spring has the function of causing the reel 410 to rotate in a positive direction to achieve the purpose of reeling the safety belt 510. The first end of the safety belt 510 is fixedly connected to the reel 410, and the second end extends to the outside of the armrest A310 and is fixedly connected to the lock buckle 520.

[0077] The first locking mechanism is arranged at the second end of the armrest B320, and the second end of the armrest B320 is provided with a first insertion hole matched with the lock buckle 520, and the first locking mechanism is used to lock the lock buckle 520 after the lock buckle 520 is inserted into the first insertion hole. The second locking mechanism is arranged on the body 100, and is used to lock the armrest mechanism.

[0078] When in use, after starting the corridor walking machine, the first driving mechanism drives the pedal 200 to move from the first working position A to the second working position A, so that a person can step on the pedal 200 and move with the lifting assembly; after the person steps on the pedal 200, firstly, the handrail A310 and the handrail B320 are rotated from the first working position B to the second working position B, and under the action of the second locking mechanism, the second locking mechanism locks the handrail A310 and the handrail B320 in the second working position B, and then the safety belt 510 is pulled out through the lock buckle 520 and the lock buckle 520 is inserted into the first plug hole, and under the action of the first locking mechanism, the first locking mechanism locks the lock buckle 520 at the second end of the handrail B320, so that the body 100, the handrail A310, the handrail B320 and the safety belt 510 are surrounded as a whole, so that the person can be surrounded, and when the elderly faint while standing on the pedal 200, they will not fall directly from the lifting assembly to the corridor, thereby avoiding secondary injury to the elderly and improving safety.

[0079] In one embodiment, the first locking mechanism includes a first locking socket 610 , a first sliding block 620 , a first elastic member 630 and a first locking block 640 .

[0080] The first locking socket 610 is provided on the lock buckle 520. The first slider 620 is slidably disposed at the second end of the armrest B320. Specifically, a first mounting cavity is provided at the second end of the armrest B320, and the first slider 620 is slidably mounted in the first mounting cavity. The first slider 620 can perform reciprocating linear motion between the first working position C and the second working position C along the width direction of the armrest B320 (i.e., the length direction of the first mounting cavity). Preferably, the first slider 620 has an operating portion extending from the outer wall of the armrest B320 to facilitate the purpose of driving the first slider 620 to move.

[0081] The two ends of the first elastic member 630 are respectively connected to the first slider 620 and the armrest B320, and in a natural state, the first elastic member 630 has a tendency to move the first slider 620 from the second working position C to the first working position C. Specifically, the first elastic member 630 is a spring, which is installed in the first installation cavity and is located at one end of the first slider 620 close to the first locking block 640.

[0082] The first locking block 640 cooperates with the first locking socket 610. Specifically, when the first locking block 640 is inserted into the first locking socket 610, the purpose of locking the lock buckle 520 can be achieved. A first slot is provided on the side of the first slider 620 facing the first socket, and the first locking block 640 is provided in the first slot. The first end of the first locking block 640 is fixedly connected to the inner wall of the first side of the first slot, and the second end extends toward the inner wall of the second side of the first slot. The distance between the end face of the second end of the first locking block 640 and the inner wall of the second side of the first slot is greater than or equal to the thickness of the lock buckle 520, so that the lock buckle 520 can be inserted into the first slot from the gap between the first locking block 640 and the first slot.

[0083] Among them, when the first slider 620 is in the first working position C, the first end and the second end of the first locking block 640 are respectively located on both sides of the first insertion hole, that is, the first locking block 640 crosses the first insertion hole. If the lock buckle 520 is inserted into the first slot from the first insertion hole before the first slider 620 moves to the first working position C, when the first slider 620 moves to the first working position C, the first locking block 640 can be inserted into the first locking insertion hole 610, thereby achieving the purpose of locking the lock buckle 520; when the first slider 620 is in the second working position C, the first end and the second end of the first locking block 640 are both located on one side of the first insertion hole, that is, the first locking block 640 is located on one side of the first insertion hole. At this time, even if the lock buckle 520 is inserted into the first slot from the first insertion hole, the first locking block 640 will not be inserted into the first locking insertion hole 610, thereby achieving the purpose of releasing the lock of the lock buckle 520. Preferably, a guide slope is provided on one side of the first locking block 640 facing the first insertion hole for moving the first slider 620 from the first working position C to the second working position C. When in use, when the lock buckle 520 is inserted into the first insertion hole, the first slider 620 moves from the first working position C to the second working position C under the action of the guide slope, thereby achieving the purpose of facilitating the insertion of the lock buckle 520 into the groove.

[0084] When in use, the lock buckle 520 is inserted from the first plug hole. Under the action of the guiding inclined surface, the lock buckle 520 uses the guiding inclined surface to make the first slider 620 overcome the elastic force of the first elastic member 630 and move from the first working position C to the second working position C, so that the lock buckle 520 can be inserted into the first slot. After the first locking socket 610 corresponds to the first locking block 640, under the action of the elastic force of the first elastic member 630, the first elastic member 630 drives the first slider 620 from the second working position C to the first working position C, and the first locking block 640 is inserted into the first locking socket 610, thereby achieving the purpose of locking the lock buckle 520.

[0085] When it is necessary to release the lock of the lock buckle 520 by the first locking mechanism, the first slider 620 is driven from the first working position C to the second working position C through the operating part, so that the first locking block 640 can be pulled out from the first locking socket 610, and finally the lock buckle 520 can be pulled out.

[0086] In one embodiment, the second locking mechanism includes a first locking toothed disc 711, a second locking toothed disc 712, a second elastic member 720, a third locking toothed disc 731, a fourth locking toothed disc 732, a third elastic member 740, a second slider 750, a fourth elastic member 760, a first rack 771, a second rack 772 and a gear 773.

[0087] The first locking toothed disc 711 is installed on the side of the body 100 facing the armrest B320, and the center line of the first locking toothed disc 711 coincides with the hinge center line of the armrest B320 and is fixedly connected to the body 100. The second locking toothed disc 712 is coaxially arranged with the first locking toothed disc 711 and is located on the side of the first locking toothed disc 711 away from the body 100. The second locking toothed disc 712 is slidably arranged in the armrest B320. Specifically, a second installation cavity is opened at the first end of the armrest B320, and the second locking toothed disc 712 is slidably installed in the second installation cavity.

[0088] The second locking toothed disc 712 can make reciprocating linear motion between the first working position D and the second working position D along the direction approaching or moving away from the first locking toothed disc 711 (i.e., the length direction of the second mounting cavity), wherein when the second locking toothed disc 712 is in the first working position D, the second locking toothed disc 712 is meshed with the first locking toothed disc 711, and when the second locking toothed disc 712 is in the second working position D, the second locking toothed disc 712 is separated from the first locking toothed disc 711.

[0089] The two ends of the second elastic member 720 are respectively connected to the second locking toothed disc 712 and the armrest B320, and in a natural state, the second elastic member 720 has a tendency to move the second locking toothed disc 712 toward the direction close to the first locking toothed disc 711. Specifically, the second elastic member 720 is a spring, which is installed in the second installation cavity and is located on the side of the second locking toothed disc 712 away from the first locking toothed disc 711.

[0090] The third locking toothed disc 731 is installed on the side of the body 100 facing the armrest A310, and the center line of the third locking toothed disc 731 coincides with the hinge center line of the armrest A310 and is fixedly connected to the body 100. The fourth locking toothed disc 732 is coaxially arranged with the third locking toothed disc 731 and is located on the side of the third locking toothed disc 731 away from the body 100, and the fourth locking toothed disc 732 is slidably arranged in the armrest A310. Specifically, a third installation cavity is opened at the first end of the armrest A310, and the fourth locking toothed disc 732 is slidably installed in the third installation cavity.

[0091] The fourth locking toothed disc 732 can make reciprocating linear motion between the first working position E and the second working position E along the direction approaching or moving away from the third locking toothed disc 731 (i.e., the length direction of the third mounting cavity), wherein when the fourth locking toothed disc 732 is in the first working position E, the fourth locking toothed disc 732 is meshed with the third locking toothed disc 731, and when the fourth locking toothed disc 732 is in the second working position E, the fourth locking toothed disc 732 is separated from the third locking toothed disc 731.

[0092] The two ends of the third elastic member 740 are respectively connected to the fourth locking toothed disc 732 and the armrest A310, and in a natural state, the third elastic member 740 has a tendency to move the fourth locking toothed disc 732 toward the direction close to the third locking toothed disc 731. Specifically, the third elastic member 740 is a spring, and the third elastic member 740 is installed in the third installation cavity and is located on the side of the fourth locking toothed disc 732 away from the third locking toothed disc 731.

[0093] The second slider 750 is installed in the armrest B320. Specifically, the armrest B320 is provided with a fourth installation cavity along its length direction, and the second slider 750 is slidably installed in the fourth installation cavity. The second slider 750 can make reciprocating linear motion between the first working position F and the second working position F along the length direction of the armrest B320. Among them, when the second slider 750 is in the second working position F, the end of the second slider 750 facing the second locking toothed disc 712 extends to the side of the second locking toothed disc 712 away from the first locking toothed disc 711 and contacts the second locking toothed disc 712, so that the second locking toothed disc 712 cannot move in the direction away from the first locking toothed disc 711. Since the first locking toothed disc 711 is meshed with the second locking toothed disc 712, under the action of the first locking toothed disc 711, the second locking toothed disc 712 cannot rotate, thereby making the armrest B320 unable to rotate, thereby achieving the purpose of locking the armrest B320. When the second slider 750 is in the first working position F, the second slider 750 is separated from the second locking gear disc 712, so that the second locking gear disc 712 can move away from the first locking gear disc 711, thereby allowing the second locking gear disc 712 to rotate, thereby achieving the purpose of unlocking the armrest B320.

[0094] The two ends of the fourth elastic member 760 are respectively connected to the second slider 750 and the armrest B320, and in a natural state, the fourth elastic member 760 has a tendency to move the second slider 750 from the second working position F to the first working position F. Specifically, the fourth elastic member 760 is a spring, which is installed in the fourth installation cavity and is located on the side of the second slider 750 facing the second locking toothed disc 712.

[0095] The first end of the first rack 771 is rotatably connected to the second locking toothed disc 712 and can make reciprocating linear motion with the movement of the second locking toothed disc 712, and the second end extends in a direction close to the fourth locking toothed disc 732. The first end of the second rack 772 is rotatably connected to the fourth locking toothed disc 732 and can make reciprocating linear motion with the movement of the fourth locking toothed disc 732, and the second end extends in a direction close to the second locking toothed disc 712. Specifically, a fifth mounting cavity is provided on the body 100, and the first rack 771 and the second rack 772 are slidably mounted in the fifth mounting cavity. The gear 773 is installed between the first rack 771 and the second rack 772 and meshes with the first rack 771 and the second rack 772, and the gear 773 is rotatably connected to the body 100.

[0096] A second insertion hole is provided on one side of the first insertion slot away from the first insertion hole, and the lock buckle 520 can pass through the second insertion hole to drive the second slider 750 from the first working position F to the second working position F.

[0097] During use, when the user steps on the pedal 200, first move the armrest A310 and the armrest B320 to the second working position, and then insert the lock buckle 520 into the first socket. During this process, the lock buckle 520 passes through the second socket and pushes the second slider 750, so that the second slider 750 overcomes the elastic force of the fourth elastic member 760 and moves from the first working position F to the second working position F. When the second slider 750 reaches the second working position F, the first locking socket 610 just corresponds to the first locking block 640. Then, under the action of the elastic force of the first elastic member 630, the first locking block 640 is inserted into the first locking socket 610, thereby achieving the purpose of locking the lock buckle 520. At the same time, since the second slider 750 has reached the second working position F, that is, the end of the second slider 750 close to the second locking gear disc 712 moves to the side of the second locking gear disc 712 away from the first locking gear disc 711 and conflicts with the second locking gear disc 712, so that the second locking gear disc 712 cannot move in the direction away from the first locking gear disc 711, thereby making the second locking gear disc 712 unable to rotate, and then making the armrest B320 unable to rotate, so as to achieve the purpose of locking the armrest B320. At the same time, since the first rack 771 and the second rack 772 are both engaged with the gear 773, the second locking gear disc 712 cannot move away from the first locking gear disc 711. Therefore, the first rack 771 cannot move, and the second rack 772 cannot move, so that the fourth locking gear disc 732 cannot move away from the third locking gear disc 731. The fourth locking gear disc 732 cannot rotate, and the armrest A310 cannot rotate, thereby achieving the purpose of locking the armrest A310.

[0098] The second locking mechanism of this structure utilizes the action of inserting the lock buckle 520 to achieve the purpose of locking the armrest mechanism, and has a simple structure and is easy to operate.

[0099] In one embodiment, a first electrode 810 and a second electrode 820 are further included.

[0100] There are two first electrodes 810, which are arranged on the input or output circuit of the control button, and the first electrodes 810 are fixedly embedded in the armrest B320. Specifically, the first electrodes 810 are fixedly embedded on the side wall of the fourth installation cavity.

[0101] The second electrode 820 is fixedly embedded on the side wall of the second slider 750, wherein when the second slider 750 is in the second working position F, the second electrode 820 contacts the two first electrodes 810, thereby connecting the circuit of the control button, thereby achieving the purpose of controlling the driving component of the corridor walker to drive the lifting component to move by pressing the control button; when the second slider 750 is in the first working position F, the second electrode 820 is staggered with at least one of the two first electrodes 810, thereby disconnecting the control circuit of the control button, thereby achieving the purpose of being unable to control the driving component of the corridor walker to drive the lifting component to move by pressing the control button.

[0102] By setting the first electrode 810 and the second electrode 820, only when the second slider 750 is in the second working position F can the driving component of the corridor walker be controlled by pressing the control button to drive the lifting component to move; when the second slider 750 is in the first working position F, the driving component of the corridor walker cannot be controlled by pressing the control button to drive the lifting component to move, thereby avoiding the user pressing the control button to control the movement of the lifting component without inserting the safety belt 510, thereby further improving safety.

[0103] In one embodiment, a third locking mechanism is further included, and the third locking mechanism is used to lock the first slider 620 in the first working position C when the control button is pressed. Specifically, during use, when the user presses the button to control the movement of the lifting assembly, the third locking mechanism locks the first slider 620 in the first working position C under the action of the third locking mechanism, thereby preventing the lock buckle 520 and the safety belt 510 from being released due to the user's accidental touching of the operating part, thereby further improving safety.

[0104] In one embodiment, the third locking mechanism includes a second locking socket 910, a locking pin 920 and a second driving structure.

[0105] The second locking socket 910 is provided on the first slider 620. The locking pin 920 is adapted to the second locking socket, that is, the locking pin 920 can be inserted into the locking socket to lock the first slider 620. The locking pin 920 is slidably arranged in the armrest B320. Specifically, a fifth installation cavity is provided on the armrest B320, and the locking pin 920 is slidably installed in the fifth installation cavity. The locking pin 920 can make a reciprocating linear motion between the first working position G and the second working position G along the direction approaching or moving away from the second locking insertion hole (i.e., the length direction of the fifth installation cavity), wherein when the locking pin 920 is in the second working position G, the locking pin 920 can be inserted into the second locking insertion hole 910, that is, when the first slider 620 is in the first working position C, since the locking pin 920 corresponds to the second locking insertion hole 910, when the locking pin 920 is in the second working position G, the locking pin 920 is inserted into the locking insertion hole, thereby achieving the purpose of locking the first slider 620 in the first working position C. When the locking pin 920 is in the first working position G, the locking pin 920 is separated from the second locking insertion hole 910, that is, the locking pin 920 is pulled out from the second locking insertion hole 910, thereby achieving the purpose of releasing the lock on the first slider 620.

[0106] The second driving structure is installed in the armrest B320, and the second driving structure is electrically connected to the control button. The second driving structure is used to drive the locking pin 920 to perform reciprocating linear motion between the first working position G and the second working position G. Specifically, when the control button is pressed, the second driving structure can be controlled by the control button to drive the locking pin 920 from the first working position G to the second working position G, thereby achieving the purpose of locking the first slider 620 in the first working position C; when the control button is stopped, the second driving structure drives the locking pin 920 from the second working position G to the first working position G, thereby achieving the purpose of unlocking the first slider 620.

[0107] The third locking mechanism of this structure has a simple structure, reasonable design and convenient operation.

[0108] In one embodiment, the second driving structure includes a fifth elastic member 930 , a permanent magnet 940 , and an electromagnet 950 .

[0109] The two ends of the fifth elastic member 930 are respectively connected to the locking pin 920 and the armrest B320, and in the natural state, the fifth elastic member 930 has a tendency to move the locking pin 920 in a direction away from the second locking socket 910. Specifically, the fifth elastic member 930 is a spring, and the fifth elastic member 930 is installed in the fifth installation cavity. The permanent magnet 940 is fixedly embedded in the end of the locking pin 920 away from the second locking socket 910. The electromagnet 950 is fixedly embedded in the armrest B320 and electrically connected to the control button, and the magnetism of the electromagnet 950 on the side opposite to the permanent magnet 940 is the same. Specifically, the electromagnet 950 is fixedly embedded in the fifth installation cavity.

[0110] During use, when the control button is pressed, the control button controls the electromagnet 950 to be energized. Since the magnetism of the electromagnet 950 and the side opposite to the permanent magnet 940 is the same, when the electromagnet 950 is energized, a magnetic repulsion force will be generated between the electromagnet 950 and the permanent magnet 940. Under the action of this magnetic repulsion force, the locking pin 920 is driven to overcome the elastic force of the fifth elastic member 930 and move from the first working position G to the second working position G. The locking pin 920 is inserted into the second locking socket 910, thereby achieving the purpose of locking the first slider 620 in the first working position C.

[0111] When the control button stops being pressed, the electromagnet 950 is de-energized, and the locking pin 920 is driven from the second working position G to the first working position G under the elastic force of the fifth elastic member 930 , thereby releasing the lock on the first slider 620 .

[0112] The second driving structure of this structure has a simple structure and a reasonable design.

[0113] The present invention also provides a corridor walking device, comprising a control component, a guide rail component installed on the corridor, a driving component installed in the guide rail component, and the above-mentioned lifting component.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

[0115] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
