A general-purpose aviation folding car

Abstract

The invention relates to a general-purpose aviation folding bicycle, which includes a main support, and the main support includes two main columns and a plurality of intermediate folding areas erected between the two main columns that can be folded into the plane between the two main columns. The flap also includes two side brackets located on both sides of the main bracket. The top of the side bracket is connected with a foldable side flap. The side bracket includes a side column and several cross beams erected between the side column and the main column. One end of the beam is fixed on the side column, and the other end of the beam is hinged on the main column, which has the degree of freedom to fold the side bracket around the main column; the present invention provides a general-purpose aviation folding bike, which ensures the reliability of folding and the stability of the car body structure. compactness.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to a general-purpose aviation folding bike. Background technique [0002] At present, the folding bicycles used by various airlines are mainly divided into: [0003] 1. Without flap, without wine rack; [0004] 2. With flap, without wine rack; [0005] 3. Without flap, with wine rack; [0006] 4. With flap and wine rack. [0007] The invention relates to an application scenario in which aircraft galleys, cabin services and manufacturers manage and upgrade product models. In flight, folding carts are mainly used to provide meal delivery services for business class. Compared with the closed box structure of dining carts, folding carts have parallel shelves that allow passengers to choose the food they need more directly, and are especially suitable for For food service in business class, folding carts generally have three shelves for storing food. According to the nee...

Problems solved by technology

When it is necessary to add a flap and a wine rack, it is necessary to add a vertical column on the left and right sides of the brackets to install and fix the flap and the wine rack. Two vertical columns have been added in addition to related accessories such as boards and wine racks. When the customer requires addition or deletion of flaps and wine racks on the basis of the original folding bike, a new model needs to be redesigned. The resulting change in folding size may As a result, the new folding bike cannot be put into the original warehouse smoothly

[0009] After the shelf is assembled, it needs to punch holes through the profile slot and the aluminum plate several times, and then knock in the spring pins to fasten the two. Drilling and installing the spring pins is very labor-intensive and affects the overall appearance

[0010] The common flap structure relies on the flap bracket to slide in the track to limit the turning angle of the flap, and when the flap is turned up to the parallel position, the bracket is pressed down to the locked position by the spring torsion. When the flap is retracted It also depends on the spring torsion to make the flap bracket slide back into the chute to store the flap. This structure often requires high dimensional accuracy of the flap bracket, and the wear and spring aging caused by long-term use will cause the flap to open and fold. Unsmooth or unable to be locked and stowed smoothly, resulting in the failure of normal use of the product
