Generally, a wheelchair is useful for moving a short distance. However, when it is necessary to travel a long distance, it is necessary to use a vehicle. In the case of a general vehicle, a disabled person or a patient with an uncomfortable motion is assisted by a carer Not only is it inconvenient for people with disabilities to move to their destination after moving, but there is not enough room for a wheelchair.

Although a vehicle capable of getting on and off the vehicle while being in a wheelchair has been developed, since the height difference between the inner bottom surface of the vehicle and the road surface is large, the disabled person or the patient who is uncomfortable with the slope of the slope gets in a wheelchair So that it is difficult to ride on the vehicle. In addition, when the vehicle rides on a wheelchair, there is a problem that the head of the handicapped person, the patient, or the like should be brought to the ceiling and the head must be bent.

To solve this problem, Patent Registration No. 10-1146177 entitled " Lower Floor Connection Structure for a Handicapped Vehicle "filed by the applicant of the present invention has been developed. 10-1146177 (hereinafter referred to as a registered patent) includes a lower floor installed on a vehicle for lowering the floor height of the vehicle, and a suspension located under the lower floor of the vehicle Wherein the suspension includes a pair of upper arms, a pair of lower arms, a pair of connecting bars connecting the pair of upper arms and the pair of lower arms, and the pair of upper arms are connected to the lower floor Wherein the lower floor is formed with a cross member at a lower portion thereof in a direction orthogonal to the longitudinal direction, the pair of lower arms being rotatably fixed to both sides of the cross member, The lower arm is characterized in that a lower portion of the coil spring connected to the disabled vehicle is fixedly installed on the upper portion.

The inclination of the slope connecting the road surface and the vehicle is reduced by lowering the inner bottom surface of the vehicle so as to make it easy for the disabled person or the patient who is uncomfortable to ride on the wheelchair to ride on the vehicle while riding in the wheelchair There is an advantage in that the head of the handicapped person, the patient, etc. is prevented from reaching the ceiling, thereby enhancing convenience for the handicapped.

However, the registered patent is also technically insufficient. In the case of the above-described patent, the lower floor supporting the wheelchair and the suspension are integrally formed, which makes it difficult to properly align the wheel alignment (hereinafter, referred to as alignment) of the vehicle. In manufacturing the vehicle, the chassis frame is assembled with other components such as a chassis by welding or the like. The chassis frame is deformed (warped or the like) due to welding at the time of manufacturing such a vehicle, , It is difficult to set the alignment of the vehicle properly, since the alignment is assembled at the twisted position (position where it does not fit properly) if the registered patent in which the lower floor and the suspension are integrated in the state that the lower floor and the suspension are integrated will be. In addition, since the lower floor and the suspension are formed into a unitary shape, there is a phenomenon that the main part is deformed due to welding or the like, and the alignment of the vehicle can not be properly corrected. Even when the lower floor and the suspension are integrally formed by welding or the like, an alignment disturbance element is generated. The alignment elements of the vehicle include a camber angle and a toe angle. In the patent, since the lower frame and the suspension are integrated into a single set, the camber angle and the toe angle It is not easy to adjust. Although the above-mentioned patent has its advantages, it is somewhat lacking in that it has a disadvantage that it is not easy to assemble the vehicle by aligning the alignment of the vehicle precisely.

In addition, in the case of the registered patent, since the alignment can not be precisely adjusted even when the vehicle is running after the lower floor and the suspension are mounted on the disabled person's vehicle, the safety is lowered and it is also difficult to expect a good ride feeling at the time of driving the vehicle. In addition to the disadvantage that the adjustment of the alignment at the time of manufacture is not properly performed, the alignment can not be properly controlled even when the vehicle is running. The camber angle and the angle of the tire can not be properly adjusted at the time of driving the vehicle, and therefore, there is insufficient in terms of the safe driving of the vehicle and a good ride feeling.

The lower floor support structure for a vehicle according to the present invention is constructed such that the main assembly 20 is not integrated with the lower floor 10 but is formed as a separate independent module so that the alignment assembly 20 is separated from the lower floor 10, Can be independently assembled to the disabled person's vehicle (2).

The alignment assembly 20 is precisely aligned with the vehicle body chassis frame 6 and the bottom portion 4 of the disabled vehicle 2 by fixing means such as bolt or welding to the correct position and then the alignment assembly 20 The lower floor 10 on which the lower portion is supported by the support frame 22 may be mounted on the bottom portion 4 of the disabled person vehicle 2 and the chassis frame 6 with fixing means such as bolts. For example, simulate precise and correct alignment of the vehicle 2, mount the alignment assembly 20 correctly onto the disabled vehicle 2 according to such simulations, and then connect the lower floor 10 to the disabled vehicle 2 In the bottom hole 4 of the lower floor 10, as shown in Fig.

Therefore, the most distinctive effect of the present invention is that the alignment of the wheel 2 (wheel) of the disabled person can be precisely adjusted by constructing the alignment assembly 20 in a separate set from the lower floor 10. There has been a disadvantage in that it is difficult to align the vehicle 2 properly, since the lower floor 10 supporting the wheelchair is integrally formed with the suspension. However, the present invention has a disadvantage in that it is difficult to properly align such a vehicle 2 The problem has been solved. As described above, when manufacturing the vehicle 2, the chassis frame 6 assembles a chassis or the like, which is another component, by welding or the like. By welding or the like at the time of manufacturing such a vehicle 2, Even if the shape of the chassis frame 6 is deformed, the alignment assembly 20, which is configured in a separate module form from the lower floor 10, Since the lower floor 10 can be installed on the vehicle body bottom 4 of the disabled person vehicle 2 after the vehicle 2 is mounted on the vehicle 2, So that it is very easy to set and align the alignment of the vehicle 2 properly. In addition, since the alignment assembly 20 is separately formed separately from the lower floor 10, there is no possibility that the main part is deformed due to welding or the like, and if the alignment of the vehicle 2 is not properly performed, It does not happen. When the lower floor 10 and the alignment assembly 20 are integrally formed by welding or the like, an alignment disturbance element may be generated due to the welding or the like. However, the alignment assembly 20 may be manufactured with a module set separate from the lower floor 10 So that alignment disturbance elements such as welding distortion are prevented from occurring. The alignment element 20 of the vehicle 2 includes a camber angle and a toe angle. Since the alignment assembly 20 is formed in a module form separately from the lower frame, It is very easy to adjust camber angle and torque angle when mounting. The present invention is a sufficiently improved invention as compared with the conventional one in that it is considerably easier to precisely align the vehicle 2 and assemble it.

As described above, since the alignment assembly 20 is formed in a separate module form separate from the lower floor 10, the alignment of the vehicle 2 can be precisely aligned and mounted, thereby enhancing the safety at the time of running the vehicle 2 And it is a great help in giving a good ride comfort in addition to the safety of the vehicle 2. [

In addition, since the camber angle and the angle of the tire of the disabled person's vehicle 2 are automatically controlled in the present invention, the disabled person's vehicle 2 can feel safer running and a better ride feeling. When the disabled person car 2 travels, a smooth alignment adjustment is automatically performed when a condition requiring alignment adjustment occurs, such as exceeding the speed limit bust.
