Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, fig. 1 is a schematic view of an overall structure of a bottom frame of a foldable vehicle according to the present invention; fig. 2 is a schematic structural view of the underframe of the folding vehicle in an unfolded state; fig. 3 is a schematic structural diagram of the underframe of the folding vehicle in a retracted state.

The utility model discloses a folding chassis for car, including floating piece and a plurality of linking piece, floating piece and each all rotate the connection between the linking piece, the action about the floating piece drives each the linking piece is gathered together or is dispersed. Specifically speaking, the floating piece moves downwards and the vehicle body is unfolded, and the floating piece moves upwards and the vehicle body is gathered, so that the convenience of storage and transportation is improved.

Each connecting piece comprises an extension connecting piece 7, and each extension connecting piece 7 is connected with each vertical supporting mechanism of the folding trolley in a one-to-one correspondence mode. Usually, extend the fixed lower extreme that sets up at the vertical support mechanism of folding car of splicing 7, consequently each extension splicing 7 is gathering together and the in-process that scatters, can drive each vertical support mechanism and gather together or scatter together, and then realize gathering together and scattering of automobile body.

In a specific embodiment, the connecting piece further comprises a plurality of bottom cross tubes 6 rotatably connected with the extension splicing pieces 7, each bottom cross tube 6 is rotatably connected with the floating piece, and the floating piece moves up and down to drive all the bottom cross tubes 6 and the extension splicing pieces 7 to gather or scatter.

In the process that the floating piece moves upwards, the inner ends of the bottom cross pipes 6 are driven by the floating piece to move upwards, and the outer ends of the bottom cross pipes 6 are still limited by the extension connecting pieces 7 to keep the height unchanged, so that the distance between the lower ends of all the bottom cross pipes 6 can be shortened, and the purpose of collecting a vehicle body is achieved; otherwise, the distances between the outer ends of all the bottom cross pipes 6 are prolonged in the downward action process of the floating piece, so that the purpose of unfolding the vehicle body is realized. The inner and outer ends of the bottom cross tube 6 are here opposite, the inner end being the end connected to the float member and the outer end being the end connected to the extension tab 7.

In a specific embodiment, the extension connecting pieces 7 are fixedly arranged at the lower end of the vertical supporting mechanism and extend horizontally, all the extension connecting pieces 7 extend towards the central shaft of the vehicle body, and the floating piece moves up and down to drive all the extension connecting pieces 7 to be kept horizontal in the process of gathering or scattering all the bottom cross pipes 6 and the extension connecting pieces 7. Because the extension connecting piece 7 has a certain length, when the bottom cross pipe 6 is almost completely gathered, a certain distance is still kept between two adjacent supporting mechanisms and the two adjacent supporting mechanisms are not in direct contact with each other, and the extension of the extension connecting piece 7 towards the central shaft of the vehicle body can ensure that the bottom cross pipe 6 can be gathered as much as possible in the folded state, so that the stability of the folded vehicle in the folded state is improved.

Further, the floating piece comprises a bottom cross support 10, the bottom cross support 10 is rotatably connected with each bottom cross pipe 6, and the bottom cross support 10 moves up and down to drive all the bottom cross pipes 6 and the extension connecting pieces 7 to gather or scatter.

Specifically, the bottom cross brackets 10 are provided with through grooves corresponding to the bottom cross pipes 6 one by one, the through grooves penetrate through the side portions of the bottom cross brackets 10, and the bottom cross pipes 6 are inserted into the through grooves one by one and are rotatably connected with the bottom cross brackets 10 through pin shafts. In other embodiments of the present invention, the bottom cross pipe 6 may be rotatably connected to the bottom cross frame 10 by providing a rotary connecting member such as a universal joint on the bottom cross frame 10.

The utility model also provides a folding car, including the above-mentioned the embodiment of the utility model provides a folding car is with chassis, above-mentioned folding car and folding car can conveniently be switched between packing up the state and the expansion state, gather together or scatter in order to drive the automobile body through the action of floating piece, are convenient for accomodate and transport, all have good stability under the arbitrary state in addition.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
