Obstacle avoiding device for disabled vehicle

Abstract

A device capable of enabling the disabled to pass through a threshold smoothly is manufactured by utilizing a physics slope labor-saving principle and utilizing the characteristics of hardness, elasticity and magnetic force of an iron plate, is simple in structure and convenient to carry, and solves the problem that the disabled can pass through the threshold when encountering the barrier when passing through the threshold. The method is technically characterized in that an iron plate is cut and formed, a flange is punched, a magnet is installed in the flange and folded into a right triangle according to a folding line marked in the figure 1, a vertex point is fixed through electric welding spot welding, and manufacturing of the obstacle avoidance device is completed. The technical scheme is not only suitable for the disabled vehicle, but also solves the problem that other vehicles are blocked when conveying goods to pass through the threshold.

Description

[0001] Belongs to the International Patent Classification Table (2013 Edition)_a: Part A - Human Life Necessities A61G: Transportation tools, special tools or living facilities specially suitable for patients or disabled people. Technical background: When disabled people use wheelchairs to travel, they often encounter non-barrier-free threshold obstacles. This special product is made by using the physical principle of inclined plane effort saving, the hardness and elasticity of iron plates, and the magnetic properties of magnets, which can enable wheelchairs to pass through thresholds smoothly. It has a simple structure and is easy to carry, solving the problem of wheelchairs being able to pass through threshold obstacles smoothly.

[0002] Invention content: 1 Use 2 mm iron plate according to the attached Figure 1 Mark the shape and size in the figure and cut it into shape. Figure 1 Mark the flange size, stamp the flange at the position, and install 3 2x3 magnets in this flange position. Figure 1 ,2,3 marked 50,100,150, and 2x3 marked length units are all millimeters) 4 Install two 2x3 magnets in the flange in the 100x150 position, 5 Install a 2x3 magnet block in the 50x100 position, 6 Use metal adhesive to fix the 2x3 magnet in the flange, 7 Follow the attached Figure 1 Fold the broken line into Figure 2 , (Top view) 8 Folded into attached Figure 3 (Side view) shape, 9 according to the attached Figure 1 The marked fold lines are folded into the attached Figure 2 , (Top view) attached Figure 3 (Side view) shape, 10 is fixed by electric spot welding at the vertex of the folded right triangle to complete the production of the obstacle avoider. The technical solution of the present invention is not only used for disabled vehicles, but also solves the problem of other vehicles transporting goods through the threshold.

[0003] Implementation plan: There are two types of disabled vehicles, one is human-driven, and the other is electrically driven. One, 1 The human-driven vehicle is pushed by the pusher to the threshold, 1 The pusher places an obstacle avoider on one side of the threshold and uses the magnet on the right angle side of the right triangle to fix it on the threshold. 2 Measure the width of the disabled vehicle, 3 Place another obstacle avoider at the same width as the disabled vehicle, and use the right angle side of the right triangle to fix the position at the appropriate width. 4 All kinds of doors currently used are iron doors, and the thresholds are also iron thresholds, with a height of 5 mm. 5 Fix an obstacle avoider first according to the width of the disabled vehicle. 6 Then fix another obstacle avoider. 7 Then install two obstacle avoiders on the other side of the threshold in the same way. There is a magnet on the side of the obstacle avoider that is adsorbed on the threshold, and the obstacle avoider will not move. Two, the electrically driven disabled vehicle is installed by the disabled person himself on both sides of the threshold using the above procedures and methods. Third, the inclined surface, plane, and side flange of the obstacle avoider are all equipped with magnets. The inclined surface, inclined surface, plane, and plane can be adsorbed to each other to form a whole, and can be placed on a disabled vehicle for easy carrying. Fourth, the 50x100 flange magnet is adsorbed on the side of the threshold when in use. A disabled vehicle can carry four obstacle avoiders. When passing through the threshold, the front two are adsorbed to one side of the threshold, and the rear two are adsorbed to the other side, forming a bridge-like uphill and bridge-like downhill form to pass through the threshold. After many experiments, the present invention has been improved and can now be proved to solve the problem of disabled people using disabled vehicles to travel, and is also suitable for other vehicles to pass through threshold obstacles.
