Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle lifting /

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle lifting / lowering system for a vehicle for transportation, and more particularly, The present invention relates to a new transit vehicle lift system.

As the five - day workweek system and the economic activities of the disabled are increased, traffic demand for the domestic traffic weakeners is increased and the bus is widely used as the right of transportation.

Public transportation such as buses are also designed for people with disabilities for boarding the disabled. A wheelchair-dependent disabled person must use a vehicle to travel a long distance. A lift or a slope is mounted on the vehicle so that the person can get on and off the vehicle without riding the vehicle whenever possible.

The public transportation bus has a bus that changes the bus so that disabled people using wheelchairs can get on the bus, which is a means of public transportation, and a lift bus that lifts the wheelchair and the boarding bus due to the sliding stop.

In the cities and local autonomous regions, low-floor buses, middle-low floor buses, and solid-state lift buses are remodeled and installed for transportation weak persons including the disabled.

However, buses for transportation weakness are a problem due to A / S problems, high cost of renovation, frequent breakdowns and risks of outflow due to dependence on the environment of the bus terminal and the import of products.

Although the number of people with disabilities is on the rise, transportation for people with disabilities and transportation weakens significantly compared to the number of persons with disabilities or transportation disabilities, which necessitates the development of public transportation means for the underprivileged .

It is necessary to develop a step lift that can aboard traffic aboard regardless of domestic bus and bus stop.

In the case of low-altitude buses currently used in each metropolitan area, it is difficult to board the slope because the inclination angle of the slope is a steep slope depending on the type of the landing platform.

In addition, it takes a long time to operate the ramp (slope) after the bus enters the lift river for the disabled to board the bus platform.

It takes about 5 to 7 minutes for the disabled to board the bus after entering the platform. Especially during the rush hour, the problem is caused by the delay of the bus which needs to be moved quickly.

Therefore, it is necessary to develop an efficient bus step lift that is easy for the handicapped to board and fast. Particularly, it is necessary to develop efficient bus step lift using wireless communication means such as WiFi.

On the other hand, the middle and low-floor buses have a lift-off type by a hydraulic lift. In case of a protruding type lift, safety handles and safety devices are not fully realized when a disabled person using a wheelchair is carried.

In case of lift type, it depends on imports, and it is very difficult to maintain due to frequent breakdown and A / S problems.

There is a problem that it is not easy to apply the lift type relatively because the burden of remodeling the bus is large to install the lift type on the bus.

It is urgently required to develop a step lift that can localize and modularize the bus step lift so that it can be fitted to domestic road conditions and common to various types of vehicles.

Domestic bus step lift technology is currently using exposure type and sliding type.

Domestic sliding-type bus steps are currently being used for low-end urban buses.

In order to operate the sliding device, the cabin driver checks the passenger with the naked eye and drives the footrest, thereby increasing the time required for boarding.

It can not be used when there is an obstacle on the ground or the height of the ramp is not fixed because it moves straightly during the operation of the slope.

When the height of the bus depot is relatively low, the vehicle body tilts sideways through the pneumatic suspension. For this reason, the low-floor bus vehicle has a relatively complicated structure, so the failure rate is relatively high.

In addition, the way of operation depends on the manpower too much, and there is a limited problem to be used by actual traffic people.

In addition, when the bus is traveling at high speed, the main technology, the confidentiality performance is degraded, and it is highly affected by the environment.

Slope type is already discontinued in overseas. If it is modified in Korea, it may cause maintenance problem.

Domestic lift type buses are used for mats except low-lying city buses.

However, the limitation of the size of the wheelchair is limited, so there is little restriction on interference when the passenger is boarded. However, when there is a large space due to the operation of the lift when getting on and off,

In addition, there is a disadvantage that a high modification cost is incurred to install the lift on the bus, and the durability is deteriorated due to unnecessary operation and environmental factors of the hydraulic system.

The type of lift type is difficult to use for conventional city bus because side door is mixed with non-disabled person and is difficult to use. There are restrictions on the type of vehicle.

Also, it is vulnerable to a safety accident when boarding a passenger with a disability by elevating the passenger from the bottom of the bus to the lift.

In the above-described configuration, the elevator lift system for a traffic abbreviated vehicle according to the present invention can be installed in a public transportation on a public basis without preparing public transportation for a disabled person (typically a bus) This is an invention that has a main feature in that it is a pedestrian lift for traffic abbreviation which is made to be carried out.

Hereinafter, the operation of the traffic abbreviation lift system according to the present invention will be described by dividing it into a general passenger mode, a disabled passenger mode, and a boarding mode. Since the present invention is typically installed in a bus among public transportation, a bus will be described as an example.

The smart bus step lift system of the present invention recognizes the approach of a weak person in advance through WiFi base, so that it can cope with the boarding quickly. The lift system of the present invention comprises a traffic abbreviation approach, a WiFi-based traffic abbreviation recognition, a signal (that is, an approach signal of a traffic weak person), a ride confirmation, a lift-off operation, and a ride.

<Public passenger mode>

In the general occupant mode, the second lifting step panel 28 is folded to overlap the upper surface of the first lifting step panel 22 and simultaneously descends downwardly of the base 10, As well. At this time, the hooking pieces 34 provided at both ends of the rotation step panel 32 are supported by the step panel support 25 provided on the base bar 14 so that the rotation step panel 32 is horizontally laid Lt; / RTI &gt; The stepped panel 32 can be held in a horizontally unfolded state because the hooked piece 34 of the turnable step panel 32 is placed on the horizontal support piece of the step panel support 25. At this time, the upper latching member 25B provided on the horizontal support piece of the step panel support body 25 prevents the rotation step panel 32 from being lifted upwards in a state in which the rotation step panel 32 is horizontally unfolded. That is, the rotation step panel 32 is held in a horizontally extended state by the horizontal support piece and the upper engagement member 25B of the step panel support body 25.

The lifting step panel 20 forms the bottom step at the bottom of the bus, and the pivoting step panel 32 extending in the horizontal direction forms an intermediate step.

Therefore, the public will step on the bottom step (floor step board) and the middle step (middle step board) and climb to the bottom of the bus (floor of the room) to complete the boarding. When ordinary people get off, they can get off the bus by stepping on the middle step and the bottom step from the bottom of the bus like a normal bus.

<Mode of boarding for disabled persons>

In case of disabled passenger mode, whether or not a traffic weak is approaching a boarding area, that is, a bus stop, is recognized on the basis of WiFi based on the approach of a traffic weak. At a bus stop stopping at the bus stop where the traffic light is entered, it is recognized by the wireless communication means such as WiFi that the traffic light person has entered the bus stop in advance, or at a distance where the bus can recognize the entry of the traffic light person while the bus is running The WiFi-based wireless communication means detects beforehand whether or not the traffic abbreviation is entered, and raises the lift step panel, which has descended to the bottom of the base, to the floor of the cabin of the bus in advance. It may be the lift primary operation described above. Then, the time during raising the lift step panel can be saved. At this time, the primary operation of the lift may be performed or omitted depending on whether or not the vehicle boarding signal is received from the traffic abbreviation side. A vehicle boarding signal accepting a boarding pass is transmitted through a terminal of a bus stop on the side of the traffic abbreviation side or the mobile terminal of the traffic abbreviation person so as to perform a primary operation of the lift when receiving a boarding signal on the bus, The operation of the lift can be omitted in the case where the vehicle has not received the boarding signal on the bus because it has not been transmitted.

In the disabled passenger mode, first, the lifting step panel 20, which was at the bottom of the base 10 in the general passenger mode, is raised by the lifting unit 50 to the cabin floor of the bus. When the piston rod is contracted while the piston rod of the lifting cylinder 52 is advanced, that is, when the piston rod is pulled, the lifting step panel 20 is lifted up to the bottom surface of the bus cabin as described above. The bus continues to run while the lifting step panel 20 is lifted up to the floor of the bus room, and the lifting step panel 20 is already in the same position as the floor of the bus room It will rise to the height.

Next, the second lifting step panel 28 is unfolded in the first lifting step panel 22 by the folding driver 40. The pinion gear 46 engaged with the rack gear 44 is rotated in one direction and the pinion gear 46 is rotated in the second direction by advancing the piston rod of the folding movable cylinder 42 and advancing the rack gear 44, Since the folding hinge shaft is coaxially coupled to the folding hinge shaft provided on the lifting step panel 28 and coupled to the folding hinge hole of the first lifting step panel 22, The second lifting step panel 28 is pivoted upwardly above the first lifting step panel 22 and unfolded in the first lifting step panel 22 as shown in FIG. Both the first lifting step panel 22 and the second lifting step panel 28 are in a horizontally unfolded state. Of course, it is natural that the door of the bus is already open before the second lifting staple panel unfolds. On the other hand, the operation of the folding movable cylinder 42 is provided with a folding movable cylinder operation button on the control panel next to the driver's seat so that the driver can push the folding movable cylinder operation button to operate the folding movable cylinder 42 have. At this time, in order to fold the second lifting step panel 28 unfolded by the folding movable cylinder 42 back to the upper surface of the first lifting step panel 22 again, if the driver presses the folding movable cylinder actuating button again, So that the lifting step panel 28 is folded back again.

The second lifting step panel 28 and the first lifting step panel 28 are then moved along the base bar 14 with the second lifting step panel 28 being extended forward from the base end of the first lifting step panel 22 22) down. The second lifting step panel 28 and the first lifting step panel 22 are lowered by the lifting unit 50 from the floor of the cabin of the bus to the bottom of the boarding pass of the bus. When the piston rod of the lifting cylinder 52 is contracted, that is, when the piston rod is again advanced with the piston rod being retracted, the first lifting step panel 22 is lowered by the second lifting step panel 28 as described above The bus goes down to the bottom of the gate. That is, substantially to the lower end of the base bar 14. [ At this time, the direct push-pull operating body 69, which is engaged in the bottom surface of the second lifting step panel 28, is pushed up by the drawing of the road and is connected to the push push pull operating body 69 When the select bracket 66 is pivoted upward by the middle hinge portion HP of the proximal end portion and the outer circumferential surface of the select operation pin 68 provided in the select bracket 66 A state in which the lower end elastic contact of the alternate operation hole 64 provided in the replace panel 62 is elastically contacted with the lower end portion of the alternate operation hole 64 of the direct connection plate provided in the separ panel 62 The separating force of the separating pin 68 is released so that the separating plate 62 is separated from the separating pin 68 provided on the separating bracket 66 ). The ejection hole 64 is formed in a long hole extending along the longitudinal path between the distal end portion and the proximal end portion of the ejection panel 62. Thus, The movable operation pin 68 is moved from one end to the other end. Specifically, in the process in which the separator panel 62 is pivoted downward, the eject operation hole 64 is moved relative to the eject operation pin 68 provided in the ejector bracket 66, And contacts the outer peripheral surface of the return operation pin 68 at the other end of the hole 64.

As described above, when the upper surface of the electret panel 62 is unfolded so as to be flush with the upper surface of the second lift step panel as the direct push-pull operating body 69 is pushed by the road surface of the road, In other words, the blank panel 62 blocks the empty space between the boundary stones (curb) and the road surface in India.

In this way, in the first lift step panel, the second lift step panel is unfolded and the wheelchair on which the disabled person aboard is extended to the first lift step panel and the second lift step panel in a state spreading up to the retract panel 62.

Subsequently, the lifting step panel 20 which has descended to the bottom of the base 10 is raised by the lifting unit 50 to the cabin floor of the bus. That is, when the second lifting step panel is unfolded in the first lifting step panel and the ejector cylinder 62 is also unfolded while the piston rod of the lifting cylinder 52 is advanced, When the piston rod is contracted, that is, when the piston rod is pulled, the lifting step panel 20 ascends to the floor of the bus cabin as described above.

At this time, the first lifting step panel 22 and the second lifting step panel 28 (see FIG. 2) are moved up to a height at which the direct push-pull operating body 69, which is inclined toward the bottom of the second lifting step panel 28, When the direct pusher pusher body 69 is elastically deformed such as a leaf spring having an elastic restoring force, when the pusher puller body 69 is resiliently deformed to its original position, The separator 66 is pivoted downward by the middle hinge portion HP of the base end portion. When the separator bracket 66 is further pivoted downward, The selector operating pin 68 provided in the selector operating hole 66 moves again from the other end of the selector operating hole 64 to the other end of the selector operating hole 64. Thus, While moving again from the end to the end, the reset panel 62 is again And is vertically erected with respect to the upper surface of the second lifting step panel 28. After the edge panel has been erected in a direction perpendicular to the upper surface of the second lifting step panel 28, the separating action pin 68 provided on the separator bracket 66 is moved back to the position And the separator 62 is held in a state in which it is erected in the vertical direction. That is, the direct push-pull operating body 69 is an elastic member, and the electret panel 62 is held in a vertical standing state by the elastic force of the elastic body.

When the split panel 62 is erected in the vertical direction, that is, in the direction perpendicular to the upper surface of the second differential step panel, the wheel of the wheelchair on which the disabled person is abutted is held behind the split panel 62, It is prevented that the wheel of the wheelchair is released to the rear of the second lifting step panel 28. The second lifting step panel 28 and the first lifting step panel 22 are provided with a second side plate and a second site plate to support the wheel of the wheel chair by being closed from the side, 1 lifting step panel 22 and the second lifting step panel 28 to the side.

In this way, when the wheelchair on which the disabled person rides is lifted above the first lifting step panel 22 and the second lifting step panel 28, the first lifting step panel 22 and the second lifting step panel 28 are continuously lifted up, To the floor of the room, and then when the wheelchair of the handicapped fully enters the cabin floor of the bus, the disabled passenger boarding is completed.

<Boarding mode>

As described above, when the disabled person boarded the bus, the second lifting step panel 28 is again folded over the first lifting step panel 22 as described above to make the lifting step panel 20 half-size. Of course, in order to fold the second lifting step panel 28 unfolded by the folding movable cylinder 42 back onto the upper surface of the first lifting step panel 22 as described above, the operator must press the folding movable cylinder actuating button The second lifting step panel 28 can be folded again.

Next, when the lifting step panel 20 is again lowered to the bottom of the bus gate, the middle folding step panel is further expanded to form an intermediate step and the lifting step panel 20 descending to the bottom forms a bottom step So that the mode is switched to a mode in which a general person can get off. On the other hand, when the disabled person aboard the bus leaves the bus, the lifting step panel 20 folded in half as in the case of the above-mentioned disabled passenger mode is again raised to the bottom surface of the bus cabin and the second lifting step panel 28 And then the second lifting step panel 28 is lifted in the first lifting step panel 22 with the wheelchair of the handicapped again lifting the second lifting step panel 28 above the first lifting step panel 22, If the step panel 22 is lowered to the lowest level of the boarding gate, the disabled person can get off the bus while the board is on the wheel.

In the present invention, the second lifting step panel 28 is folded over the first lifting step panel 22 and folded in half. Hereinafter, the second lifting step panel 28 is referred to as the first lifting step panel 22, The lifting step panel 20 folded over the lifting step panel 22 and folded in half is referred to as a folding lifting step panel 20) descends to the bottom floor of the bus entrance, When the folding lifting step panel 20 is lifted up, the folding lifting step panel 20, which has been extended in the horizontal direction, is raised in the vertical direction, and the folding lifting step panel 20 is moved up to the boarding room of the bus. The second lifting step panel 28 of the folding lifting step panel 20 is unfolded again at the height of the boarding room and the lifting step panel 20 is again lifted up to the entrance door of the bus The pivoting step panel 32 (which may be referred to as the upper step) which is erected in the vertical direction is further extended in the horizontal direction, and when the lifting step panel 20 is completely lowered to the bottom of the riding entrance of the bus The second lifting step panel 28 in the lifting step panel 20 is again folded over the first lifting speck panel 22 and the folding lifting step panel 20, and the door of the bus is closed when the folding lifting step panel 20 descends to the bottom of the bus stop.

&Lt; Maintaining the horizontal state of the rotation step panel 28 in the general person boarding mode >

The folding lift step panel 20 in the folded state (lift folded state) of the lifting step panel 20 is lowered to the bottom of the bus entrance and the pivoting step panel 28 is moved to the step panel support 25 Lt; / RTI &gt; The stepped panel support body 25 is placed on the cam plate by placing the hooked piece 34 provided on the side surface of the rotation step panel 28 on the step panel support body 25.

The present invention is very meaningful in that it can provide a technique of public transportation means for such a traffic weak person.

In addition, it is necessary to develop a step lift capable of aboard a traffic aboard regardless of the domestic bus and bus stop, and the present invention is an invention capable of meeting these demands faithfully.

In the present invention, the first lifting step panel 22 and the first lifting step panel 22, which are stably extended in the horizontal direction, and the second lifting step panel 22, which is stably opened in the horizontal direction, 2 If only the wheelchair on which the disabled person rides is lifted on the lifting step panel (28), the wheelchair can be stably mounted on the lifting step panel (28).

In addition, although it takes a long time for the disabled person to ride on the bus platform, the bus takes a long time to operate the ramp (slope) after entering the ascending river, but the present invention is applicable to a case where the wheelchair of the handicapped rises, It takes less. Therefore, the present invention provides an efficient bus step lift that is easy for a disabled person to ride and fast.

In addition, a hydraulic lift is installed on a conventional low-to-middle bus. In the case of a protruding type lift, there is an unstable element on the passenger's hand because the safety handle and the safety device are not completely realized when a disabled person using the wheelchair is carried. Because it is not a protruding type, the anxiety factor on such a boarding is completely solved.

In addition, although the conventional lift type relies on imports, maintenance due to frequent breakdowns and A / S problems is difficult, but the present invention is effective in replacing imports without relying on such imports, There are few problems, and maintenance problems due to A / S problems are also solved.

In addition, there is a problem that it is difficult to apply the lift type to the bus because of a large burden of remodeling the bus. However, the present invention significantly reduces the burden of converting the bus, so that the application of the lift type is relatively easy.

The present invention has the effect of minimizing installation space through step modularization. Although the range and cost of the bus are not standardized according to the lifts used in the domestic market, the present invention minimizes the installation space by modularizing the structure and appearance of the bus step lift. According to the present invention, a modularized step lift is provided in the space between the floor of the cabin and the door (especially the rear door) to minimize the installation space. Further, by modularization of the step lift, Even if a low-floor bus is not designed, it can be easily installed on a general bus.

The present invention is a very valuable invention in that it is able to provide a step lift that can be fitted to domestic road conditions and common to various types of vehicles by localizing and modulating the bus step lift.
