[0029] As shown in Figures 1-4 , as an embodiment of the practical new type, a telescopic column linkage mechanism for a folding vehicle is provided, comprising a lower support column 1, an upper support column 2, a linkage structure, and an operating structure 100. The upper support column 2 is telescopically arranged in the lower support column 1 and can move up and down along the lower support column 1. The linkage structure comprises a linkage column 3 arranged side by side on the side of the upper support column 2 and spaced apart from the upper support column 2, a fixing member 4 arranged at the upper end of the linkage column 3, and a sliding member 5 arranged at the lower end of the linkage column 3.

The operating structure 100 is connected to the linkage structure and can drive the upper support column 2 to move up and down relative to the lower support column 1 by applying force to the linkage structure. When folding, the operating structure 100 can apply force to the linkage structure and drive the linkage structure to slide downward along the lower support column 1 through the sliding member 5, and then drive the upper support column 2 to move downward relative to the lower support column 1 through the fixing member 4 of the linkage structure and be accommodated in the lower support column 1, thereby shortening the height of the telescopic column linkage mechanism, so that the folding vehicle provided with the telescopic column linkage mechanism can shorten the overall height after folding, reduce the space occupation height after folding, and be suitable for being accommodated in some lower accommodation space, facilitating packaging, transportation or carrying. When unfolding, the operating structure 100 can apply force to the linkage structure and drive the linkage structure to slide upward along the lower support column 1 through the sliding member 5, and then drive the upper support column 2 to move upward relative to the lower support column 1 through the fixing member 4 of the linkage structure, thereby raising the height of the telescopic column linkage mechanism, so that the folding vehicle provided with the telescopic column linkage mechanism can raise the overall height after unfolding, thereby increasing the size of the built-in object space of the folding vehicle and being able to carry more objects.

A sliding channel 511 matched with the lower support column 1 is longitudinally arranged on the sliding body 51, and the lower support column 1 is telescopically sleeved in the sliding channel 511, and the mounting grooves 521 are arranged at the side of the sliding channel 511, and the transverse movement of the lower support column 1 relative to the sliding body 51 can be limited by the sliding channel 511, thereby improving the stability of the sliding connection between the lower support column 1 and the sliding body 51.

Of course, in other embodiments, the folding support can also be provided with one or more, and the lower hinged base 53 on the sliding member 5 can also be provided with one or more corresponding to the number of folding supports, and these operating structures 100 can be used to drive the linkage structure to move up and down relative to the lower support column 1.
