Description

Design method for simultaneously installing seat and wheelchair in concave-convex floor type passenger car

Technical Field

The invention relates to a design technology of a luxury passenger car body structure, in particular to a design method for simultaneously installing a seat and a wheelchair in a concave-convex floor type passenger car.

Background

In order to continuously facilitate daily travel of people, the urban passenger car is continuously developed to the direction of low entrance and low floor from the original high floor and secondary stepping structure. In particular, in order to meet the riding requirements of special people, more and more low-entrance/low-floor vehicles are provided with turning plates for the disabled wheelchair at the entrance of a passenger door, and the disabled wheelchair space is reserved in the vehicle and is provided with a related fixing device. The floor space area required by one disabled person wheelchair region is generally 800mm wide and X1300mm long, and two disabled person regions arranged in front and back generally need a space of 800mm wide and X2600mm long. In order to facilitate the getting-on of the wheelchair for the disabled and the operation thereof in the vehicle to push the wheelchair into the disabled area, the vehicle is required to be of a flat panel structure, most importantly, at least from the passenger door entrance where the flap is installed to the disabled wheel chair arrangement area, in addition to the installation of a manual or electric flap at the door entrance.

However, in the common low entrance/low floor vehicle, the wheelchair for the disabled is generally arranged on the low floor ground with the same floor height as the passenger, but in some cases, the vehicle cannot be made into a flat floor but is required to be made into a concave-convex floor due to specific requirements of the customer, and meanwhile, the seat is required to be installed on the convex floor in the vehicle or the wheelchair for the disabled is required to be arranged, so that how to design a method for installing the seat and the wheelchair on the convex floor in the concave-convex floor type passenger vehicle at the same time is researched, and the invention is a brand new problem in the structural design of the passenger vehicle to be solved by the invention.

Detailed Description

The invention is further described below with reference to the figures and examples.

Example (b): see fig. 1-5.

A design method for simultaneously installing a seat and a wheelchair in a concave-convex floor type passenger car comprises the following steps:

1) dividing the structural arrangement of the concave-convex floor;

2) the detachable seat and the wheelchair are fixed on the raised floor in a region;

3) the raised floor and low floor area transition and lifting wheelchair design.

As shown in figures 1 and 2, the raised floor (the external dimension area is 1000mm wide and X2709mm long) is reasonably divided and arranged, and a local structure close to the tail end of a middle passenger door and within the range of 800mm wide and X1252mm is made into a liftable movable floor. As can be seen from the figure, the movable flap with the width of 800mm is provided with a raised floor with the width of 100mm on both sides, and the movable floor is arranged at the tail end of the raised floor with a concave shape. The movable turning plate is turned over around the front section 4 thick-wall stainless steel hinges by a pair of cylinders arranged at the bottom of the floor in a telescopic motion; meanwhile, 3 groups of aluminum alloy chutes are arranged on the floor surface and are used for installing the quick-release type seat legs, wherein the 3 rd group of aluminum alloy chutes are arranged on the floor with the width of 100mm and the height of 240mm at two sides of the movable turning plate; the front and back 2 groups of disabled wheelchair ground fixing devices are arranged and used for fixing front and back pull belts of the disabled wheelchair, wherein the last two fixing points are arranged on the movable turning plate. The automatic turning plate is in a put-down state when the cylinder is retracted through the lifting button arranged on the operation side wall; when the cylinder extends out, the automatic turning plate is lifted to be in a state of being flush with a step with the height of 240 mm.

As shown in fig. 3, when the area is used as a seat arrangement area, the two-seat 3 sets (6 seats) with 3 sets of quick-release type seat legs are installed through 3 sets of aluminum alloy sliding grooves on the floor and are all at the same installation height. At this time, the comfort of the third row of passengers can be ensured only by keeping the movable floor in the raised state all the time. As seen from the side view, a pair of (1 piece on the left and the right) quick-release chair legs are arranged on a double seat, and the quick-release chair legs can be quickly detached and installed by operating the handles of the quick-release chair legs.

As shown in fig. 4 and 5, when the area is used as a wheelchair arrangement area for the disabled (at this time, 3 sets of double seats need to be removed), the lifting button is operated, the cylinder is retracted, the automatic turning plate is turned around the hinge of the front section, the tail end of the automatic turning plate falls down to form a slope with the ground of the low floor, and the operation is smooth and excessive, so that the wheelchair can be pushed onto the movable floor. If the wheelchair is parked at the front wheelchair fixing position, the wheelchair can be continuously pushed forwards and fixed. When the second wheelchair is pushed onto the slope-shaped automatic turning plate, the lifting button is operated, the cylinder extends out, the automatic turning plate bears the wheelchair and rises to be flush with the raised floor with the height of 240mm, finally, the ground drawstring of the wheelchair is installed on the corresponding ground fixing device, and the shoulder belt is installed in place. Like this, realized two disabled person's wheelchairs fixed on protruding floor, simultaneously, the wheelchair passenger all is in the same height of taking in the car with the passenger on other seats, has better riding visual comfort.

Although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention.
