Description

Electric disabled wheelchair lift

The present invention relates to an electric wheelchair lift for the disabled that moves electrically and accurately positions a wheelchair with a disabled person seated in it at the entrance or exit of a train so as to allow the wheelchair to be boarded by the disabled person.

Typically, in order for a disabled person using a wheelchair to board a train, at least two to three crew members had to lift the wheelchair containing the disabled person and help them onto the train.

Here, there is a problem that several people must be mobilized to work manually to safely get a wheelchair carrying a disabled person onto the train.

To solve these problems, wheelchair lifts have been developed and are being used to safely transport disabled passengers in wheelchairs onto trains.

The background technology of the present invention is disclosed in Patent Registration No. 10-1427150, which was applied for and registered with the Korean Intellectual Property Office and published on July 31, 2014.

The purpose of the present invention is to provide an electric wheelchair lift for the disabled that can move electrically and accurately position the wheelchair at the entrance or exit of a train so that a disabled person sitting in the wheelchair can board the train.

According to one embodiment of the present invention, an electric wheelchair lift for the disabled includes a boarding/disembarking member (100) that guides a wheelchair with a disabled person on board from a platform (20) to a train (10) or from a train (10) to a platform (20), a moving vehicle (200) that moves the boarding/disembarking member (100), an elevating member (300) that is equipped on the moving vehicle (200) to elevate the boarding/disembarking member (100), and a control unit (600) that controls the elevating member (300) and the moving vehicle (200), and the moving vehicle (200) includes a moving frame (210) positioned below the boarding/disembarking member (100), front wheels (220) that are equipped at the front on both sides of the moving frame (210), rear wheels (230) that are equipped at the rear on both sides of the moving frame (210), and It is characterized by including a driving unit (240) that is fixed and rotates each of the front wheels (220).

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

As illustrated in the attached drawing, an electric wheelchair lift for the disabled according to an embodiment of the present invention comprises a boarding/disembarking member (100) that guides a wheelchair with a disabled person on board from a platform (20) to a train (10) or from a train (10) to a platform (20), a moving vehicle (200) that moves the boarding/disembarking member (100), an elevating member (300) that is equipped on the moving vehicle (200) and elevates the boarding/disembarking member (100), a distance measuring unit (400) that is equipped on the moving vehicle (200) and measures the distance from the moving vehicle (200) to the train (10), a position detection unit (500) that is equipped on the moving vehicle (200) and detects whether the moving vehicle (200) is aligned with the entrance/exit (11) of the train (10), and a controller that controls the boarding/disembarking member (300) and the moving vehicle (200). It includes a control unit (600) that restricts the movement of a moving vehicle (200) based on the measurement of a distance measuring unit (400) and restricts the lifting and lowering of a lifting member (300) based on the detection of a fixed position detection unit (500).

The boarding and disembarking member (100) includes a boarding plate (110) on which a wheelchair boards, a boarding side plate (120) that is rotatably provided at the front end of the boarding plate (110) and is rotated to provide a path for boarding the wheelchair when laid down on the platform (20), a train side plate (130) that is rotatably provided at the rear end of the boarding plate (110) and is rotated to provide a path for disembarking the wheelchair when laid down on the train (10), and double-sided fences (140) that stand up on both sides of the boarding plate (110) to prevent the boarded wheelchair from falling.

The board (110) is formed with a larger area than the wheelchair and has a rough surface to prevent the wheelchair from slipping when seated.

The boarding side plate (120) is rotated and supported on the platform (20), thereby providing a path for the wheelchair to move from the platform (20) to the boarding platform (110). Accordingly, the wheelchair can move from the platform (20) to the boarding platform (110) or from the boarding platform (110) to the platform (20) via the boarding side plate (120).

And when the lift side plate (120) is rotated in reverse and stands up, it covers and protects the wheelchair. In other words, it can prevent the wheelchair from falling.

The train side plate (130) is rotated and supported on the floor of the doorway (11) formed in the train (10), thereby providing a path for the wheelchair to move from the doorway (11) of the train (10) to the boarding platform (110). Accordingly, the wheelchair can move from the boarding platform (110) to the train (10) or from the train (10) to the boarding platform (110) via the train side plate (130).

And when the train side plate (130) is rotated in reverse and stands up, it covers and protects the wheelchair. In other words, it can prevent the wheelchair from falling.

Here, the elevator side plate (120) and the train side plate (130) can be firmly maintained in an upright state by being hung on their respective rings. In addition, the user can conveniently rotate the elevator side plate (120) or the train side plate (130) to lie down or stand up by using the handles formed on each of the elevator side plate (120) and the train side plate (130).

The double-sided fence (140) is formed in a roughly '∩' shape so that both sides of the wheelchair are covered and a disabled person sitting in the wheelchair can hold it with his or her hand, thereby ensuring the stability of the passenger when getting on and off the boarding platform (110).

In addition, the two-sided fence (140) can be formed with a handle that the user can hold, so that the user can manually push it to move the boarding/disembarking member (100).

In this way, the wheelchair is covered on all sides by a plurality of double-sided fences (140) and an erected boarding side plate (120) and a train side plate (130), so the stability of the passenger can be guaranteed.

Furthermore, the boarding/disembarking member (100) includes a left/right adjustment unit (150) that moves the boarding plate (110) left/right.

The left-right adjustment unit (150) includes a plurality of fixed blocks (151) that are spaced apart from each other on both sides of a moving vehicle (200) and are fixed to a lifting member (300), a ball screw (152) that is fixed to the fixed blocks (151) so that both ends can rotate, a guide shaft (153) that is fixed to the fixed blocks (151) at both ends, a moving block (154) that is screw-connected to the ball screw (152) and is fixed to the boarding/disembarking member (100) while the guide shaft (153) passes through it, and a handle (155) that rotates the ball screw (152).

The fixed block (151) is fixed to the boarding plate (310) of the boarding member (300) described later. The moving block (154) is fixed to the boarding plate (110) of the boarding member (100).

Accordingly, when the handle (155) is rotated, the ball screw (152) is rotated, and thus the boarding plate (110) of the boarding/disembarking member (100) to which the moving block (154) is connected is moved. In other words, when the user operates the handle (155), the boarding/disembarking member (100) of the moving vehicle (200) is moved to the left or right.

A moving vehicle (200) includes a moving frame (210) positioned at the bottom of a boarding/disembarking member (100), front wheels (220) provided at the front on both sides of the moving frame (210), rear wheels (230) provided at the rear on both sides of the moving frame (210), and driving units (240) fixed to both sides of the moving frame (210) to rotate the front wheels (220).

The moving frame (210) can be formed into a square shape by connecting shafts and having a width equal to or slightly larger than the width of the boarding/disembarking member (100).

When the driving units (240) are controlled by the control unit (600) to rotate the front wheels (220), the moving frame (210) moves.

Therefore, when the driving units (240) operate simultaneously, the front wheels (220) rotate simultaneously, so the moving vehicle (200) moves forward. Of course, when the front wheels (220) rotate simultaneously in reverse by the driving units (240), the moving vehicle (200) moves backward.

And when the driving unit (240) on one side stops the front wheel (220) on one side and the driving unit (240) on the other side rotates the front wheel (220) on the other side, the moving vehicle (200) rotates around the stopped front wheel (220). Also, when the driving unit (240) on one side rotates the front wheel (220) on one side at a low speed and the driving unit (240) on the other side rotates the front wheel (220) on the other side at a high speed, the moving vehicle (200) moves while rotating around the front wheel (220) on one side that rotates at a low speed.

In addition, the moving vehicle (200) includes a stopper (250) that protrudes from the end to prevent a collision with the train (10). The stopper (250) may be configured in multiple pieces and fixed to both sides of the front end of the moving vehicle (200), and may be configured with a cushioned portion such as rubber, and a screw shaft that protrudes from the cushioned portion and is screw-connected to a nut installed on the moving vehicle (200). Accordingly, the length at which the stopper (250) protrudes from the moving vehicle (200) can be adjusted by rotating the screw shaft screw-connected to the nut. In other words, by presetting the protruding degree of the stopper (250), the moving vehicle (200) can be prevented from colliding with the train (10) by the stopper (250) being supported by contacting the train (10).

Furthermore, a warning unit (260) that warns when the driving unit (240) of the moving vehicle (200) is in operation may be installed. This warning unit (260) may be composed of a warning light that warns with light and an alarm that warns with sound. Accordingly, since the warning unit (260) warns the outside while the moving vehicle (200) is moving, passengers in the vicinity can be careful.

The lifting member (300) comprises a lifting plate (310) connected to a boarding/disembarking member (100), a one-side shaft (320) whose one end is rotatably fixed to the lifting plate (310) and whose other end is slidably fixed to a moving vehicle (200), a second-side shaft (330) whose one end is rotatably fixed to the moving vehicle (200) and whose other end is slidably fixed to the boarding/disembarking member (100) and whose middle portion is rotatably connected to the one-side shaft (320), a rotary pin (340) that rotatably connects the central portions of the one-side shaft (320) and the other-side shaft (330), and a cylinder shaft that is rotatably provided on the moving vehicle (200) and connected to the rotary pin (340) so that the one-side shaft (320) and the other-side shaft (330) perform a scissor motion to raise/lower the lifting plate (310). Includes an elevator cylinder (350).

The boarding plate (310) is located between the moving frame (210) of the moving vehicle (200) and the boarding plate (110) of the boarding/disembarking member (100).

The one-side shaft (320) may have projections formed on both ends. One end of the projection is fixed rotatably by penetrating a hole formed in the elevator plate (310), and the other end of the projection is fixed slidably by penetrating a long hole formed in the moving vehicle (200). Accordingly, the one-side shaft (320) may be rotated at one end on the elevator plate (310) while the other end may slide on the moving vehicle (200). The one-side shaft (320) may be configured in multiple numbers and installed on both sides of the elevator plate (310).

The other shaft (330) is formed in the same manner as the one shaft (320), and one end of the projection penetrates a hole formed in the moving vehicle (200) and is rotatably fixed, and the other end of the projection penetrates a long hole formed in the elevator plate (310) and is slidably fixed. Accordingly, the other shaft (330) can be slid on the elevator plate (310) while one end rotates on the moving vehicle (200). The other shaft (330) may be configured in multiple numbers and installed on both sides of the moving vehicle (200).

The rotary pin (340) is fixed by penetrating the portion where the one-side shaft (320) and the other-side shaft (330) overlap. Therefore, the one-side shaft (320) and the other-side shaft (330) can perform a scissor motion around the rotary pin (340). More specifically, the rotary pin (340) is formed with a length equal to the width of the lifting plate (310) and is fixed by penetrating the one-side shaft (320) and the other-side shaft (330) where one end overlaps and is positioned on one side, and the other end is fixed by penetrating the one-side shaft (320) and the other-side shaft (330) where the other end overlaps and is positioned on the other side. Therefore, at both ends of the rotary pin (340),

The lifting cylinder (350) extends a cylinder shaft whose end is rotatably connected to a rotary pin (340) and is rotatably installed on a moving vehicle (200). This lifting cylinder (350) is operated by hydraulic pressure or pneumatic pressure to extend the cylinder shaft.

Accordingly, when the lifting cylinder (350) extends the cylinder shaft, the cylinder shaft pushes the rotary pin (340), so that the one-side shaft (320) and the other-side shaft (330) perform a scissor motion, and the lifting plate (310) of the moving vehicle (200) can be raised together with the boarding/disembarking member (100).

Conversely, when the lifting cylinder (350) contracts the cylinder shaft, the cylinder shaft pulls the rotary pin (340), so that the one-side shaft (320) and the other-side shaft (330) perform a scissor motion in the opposite direction, and the lifting plate (310) is lowered together with the boarding/disembarking member (100) and is placed on the moving vehicle (200).

The distance measuring unit (400) may be composed of a light sensor or an infrared sensor. Accordingly, it is possible to detect that a moving vehicle (200) is approaching a train (10) through an object detection sensor (500).

The position confirmation unit (500) may be configured as a laser pointer that irradiates a laser. Since the laser irradiated from the laser pointer is irradiated to the train (10), the user can visually confirm the laser irradiated to the train (10) and control the moving vehicle (200) to accurately approach the train (10).

And the position confirmation unit (500) includes a laser irradiation unit (510) that irradiates a laser toward the train (10), and an upper and lower diffusion unit (520) that transmits the laser irradiated from the laser irradiation unit (510) and diffuses it vertically.

The laser irradiation unit (510) irradiates the laser in a straight line to form a dot shape on the surface of the target object.

The upper and lower diffusion unit (520) is configured as a lens in which the incident surface is flat and the exit surface is formed convexly, but the width in the left and right directions is narrower than the width in the up and down direction. Accordingly, the diffused laser is formed in a long straight shape in the up and down direction and can be irradiated on the surface of the target object. In this way, since the laser is irradiated on the outer surface of the train (10) in a long straight shape in the up and down direction, visibility is increased, and the user can easily check the degree to which the laser is close to the entrance (11) of the train (10).

Here, the position confirmation unit (500) can be formed on one side of the moving vehicle (200).

Accordingly, the laser beam that is emitted vertically from the position confirmation unit (500) is emitted to the outer surface of the train (10), so that the user moves the moving vehicle (200) so that the straight laser beam is emitted close to one side of the entrance (11). In other words, when the straight laser beam is emitted to one side of the entrance (11), the moving vehicle (200) is aligned with the entrance (11) of the train (10).

In this state, when the train side plate (130) of the boarding/disembarking member (100) is rotated and inserted into the entrance (11) of the train (10), the train side plate (130) can be easily inserted into the inside of the entrance (11) without interfering with one side or the other side of the entrance (11).

Here, a reflector (12) is formed to reflect a laser irradiated from a position confirmation unit (500) on one side of the entrance (11) of the train (10). The reflector (12) is attached to the outer surface of the train (10) and may be formed of a reflective film whose cross-section of the reflective surface that reflects the laser is triangular and continuously formed from top to bottom. Accordingly, the laser incident on the lower reflective surface of the triangular reflective surface is reflected downward and irradiated onto the floor of the platform (20). At this time, the lasers reflected from the lower reflective surfaces are irradiated onto the floor of the platform (20) in a straight line.

Accordingly, the laser beam emitted vertically from the position confirmation unit (500) is reflected from the reflection unit (12) formed close to the entrance (11) of the train (10) to the platform (20). At this time, the user can visually check the laser reflected from the reflection unit (12) of the train (10) to the platform (20) to determine whether the moving vehicle (200) is perpendicular to the train (10).

And, the laser incident on the reflector (12) from the position confirmation unit (500) and the laser reflected from the reflector (12) to the platform (20) can be confirmed. In other words, if the incident laser and the reflected laser overlap each other, it can be known that the moving vehicle (200) is not in a right-angled shape with respect to the outer surface of the train (10), and if the incident laser and the reflected laser do not overlap each other, it can be known that the moving vehicle (200) is not in a right-angled shape with respect to the outer surface of the train (10).

In this case, when the laser reflected onto the platform (20) does not form a right angle to the outside of the train (10), the user controls the moving vehicle (200) so that the laser reflected onto the platform (20) forms a right angle to the outside of the train (10). In this state, when the train side plate (130) of the boarding/disembarking member (100) is rotated and inserted into the entrance (11) of the train (10), the train side plate (130) can be easily inserted into the inside of the entrance (11) without interfering with one side or the other side of the entrance (11).

The control unit (600) includes a moving vehicle operating unit (610) that operates a moving vehicle (200), an elevator operating unit (620) that operates an elevator unit (300), a position detection operating unit (630) that operates a position detection unit (500), a reference distance setting unit (640) that sets a first reference distance and a second reference distance, a distance confirmation unit (650) that confirms a distance measured by a distance measurement unit (400), a distance judgment unit (660) that compares the distance confirmed by the distance confirmation unit (650) with the first reference distance and the second reference distance to determine whether the first or second reference distance matches, a position operation unit (670) that operates the position detection operating unit (630) so that the position detection unit (500) is operated when the distance judgment unit (660) determines the first reference distance. When the second reference distance is determined, a moving operation unit (680) is included that operates the moving vehicle operation unit (610) to stop the moving vehicle (200).

Here, the first reference distance is set longer than the second reference distance. The first reference distance is a distance corresponding to a state in which the moving vehicle (200) is separated from the train (10), and the second reference distance is a distance corresponding to a state in which the moving vehicle (200) is close to the train (10).

And the position control unit (670) is set to operate the position detection operating unit (630) so that the position detection unit (500) stops when the distance judgment unit (660) determines the second reference distance.

In this way, the user operates the control unit (600) to move the moving vehicle (200) on the platform (20). Then, the boarding side plate (120) of the boarding/disembarking member (100) is rotated downward to be positioned on the floor of the platform (20). In this state, a disabled person uses a wheelchair to move along the boarding side plate (120) of the boarding/disembarking member (100) and boards the boarding plate (110) of the boarding/disembarking member (100). Then, the boarding side plate (120) of the boarding/disembarking member (100) is rotated upward to stand up. In other words, as the boarding side plate (120) stands up, the wheelchair can be prevented from being detached from the end of the boarding plate (110). Of course, since the train side plate (130) of the boarding/disembarking member (100) is also in an upright state, the wheelchair can be prevented from falling to the other end of the boarding plate (110).

Then, the user operates the moving vehicle (200) to prepare to approach the train (10) entering the platform (20).

Then, when the train (10) enters the platform (20) and stops, the user operates the moving vehicle (200) to approach the train (10). In addition, the doorway (11) of the train (10) is opened so that passengers can board.

When the distance measured by the distance measuring unit (400) matches the first reference distance, the position detection unit (500) is automatically operated. That is, a laser is irradiated to the train (10) from the position detection unit (500) that is automatically operated.

Therefore, while the user visually confirms the laser being irradiated onto the train (10), the user continuously manipulates the direction of the moving vehicle (200) while driving the moving vehicle (200) so that the laser is irradiated onto the reflector (12) of the train (10). At this time, the laser reflected from the reflector (12) is irradiated onto the platform (20). The user visually confirms whether the direction of the laser irradiated from the position detection unit (500) and the direction of the laser reflected from the reflector (12) are identical. If the directions of the lasers do not match, the user continuously manipulates the moving vehicle (200) so that the directions of the lasers match.

When the directions of the lasers are aligned in this way, the moving vehicle (200) is aligned with the entrance (11) of the train (10). In this state, the moving vehicle (200) approaches closer to the train (10) by the user's operation, so the boarding/disembarking member (100) approaches the entrance (11) of the train (10). At this time, when the distance measured by the distance measuring unit (400) matches the second reference distance, the moving vehicle (200) automatically stops. In other words, the moving vehicle (200) is prevented from colliding with the train (10).

Furthermore, if the distance measured by the distance measuring unit (400) matches the second reference distance, the position detection unit (500) automatically stops and does not irradiate the laser.

Next, when the train side plate (130) of the boarding/disembarking member (100) is rotated downward, the train side plate (130) is inserted into the entrance (11) and fixed. Then, a disabled person enters the interior of the train (10) using a wheelchair.

Finally, when the disabled person has finished boarding the train (10), the train side plate (130) of the boarding/disembarkation member (100) is rotated upward to stand up. That is, the moving vehicle (200) moves backward away from the train (10) while the standing train side plate (130) does not interfere with the entrance (11) of the train (10). Then, when the disabled person has finished boarding, the entrance (11) is closed and the train (10) departs from the platform (20).

In addition, the present invention can be usefully used when a wheelchair carrying a disabled person gets off a train (10) at a platform (20).

Those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical idea or essential characteristics thereof. Therefore, the embodiments described above should be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the claims described below rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
