Description
Technical Field
The utility model relates to a folding vehicle, in particular to a folding vehicle capable of being rapidly unfolded and stored by a single operator.
Background
The folding frame is widely applied to the field of storage because of effective utilization of upper space.
Most of the folding frames in the current market are household storage folding frames, and the folding frames are assembled by self and folded by utilizing a central axis to form the maximum space saving. The storage rack after folding is still large in area of the largest surface although effectively compressed in thickness, so that vehicle-mounted transportation is difficult, and the folding mode is easy to automatically fold under the condition of misoperation, so that the frame is easy to deform, the whole structure is unstable, the bearing capacity is poor, and heavy electromechanical equipment cannot be borne. Therefore, the application range of the folding frame is mostly limited in light-weight limited scenes such as household scenes, and the folding frame is difficult to popularize in wider fields.
At present, the following several existing technologies specifically exist in the storage field:
(1) Center axis folding mode: the existing chinese patent document CN215649870 provides a multi-layered folding frame, which comprises a left side frame and a right side frame, wherein a top layer and a multi-layered folding layer are sequentially arranged between the left side frame and the right side frame from top to bottom, the left end and the right end of the multi-layered folding layer are respectively and sequentially connected to the left side frame and the right side frame from top to bottom through shafts, the positioning end of the top layer is connected to the top end of the left side frame through shafts, and the swinging end of the top layer swings around the positioning end of the top layer so as to be folded on the left side frame; the front side of the multi-layer folding layer is vertically provided with a linkage vertical rod which is respectively connected with the middle folding position of the multi-layer folding layer through a shaft; the vertical limiting groove penetrating the body of the vertical link rod is vertically formed in the vertical link rod, a U-shaped limiting block is further arranged on the vertical link rod in a sliding mode, a plum blossom handle bolt in threaded connection with the U-shaped limiting block is arranged in the vertical limiting groove, connecting rods are arranged between the plum blossom handle bolt and front upright posts of the left side frame and the right side frame, and tops of the two groups of connecting rods are respectively connected with front upright posts of the left side frame and the right side frame in a shaft mode. Therefore, a central shaft type folding mode is realized, and folding and unfolding are realized through up-and-down movement of the linkage vertical rod at the central shaft. However, the above-described structural folding frame has the following drawbacks: the folded area is too large, is easy to deform along the central axis and has poor bearing capacity, so the folded medical device is not suitable for medical scenes.
(2) Integral folding mode: the prior China patent document CN108116469A provides an aviation folding vehicle, the main folding structure of which is two main upright posts, a main folding zone is positioned between the two main upright posts, and one side edge of a middle turning plate frame (shelf) is hinged on the main force post and is folded towards the main folding zone; the side supports are arranged on two sides of the main support, the tops of the side supports are connected with foldable side turnover plates, a plurality of cross beams are connected between the side stand columns and the main stand columns, one ends of the cross beams are fixed on the side stand columns, the other ends of the cross beams are hinged on the main stand columns, and the side turnover plates on two sides are folded inwards by taking the main stand columns as rotating shafts. One side edges of the upper plate and the lower plate are respectively hinged on the two lower support rods. The aircraft body itself is small, so this integral folding is adopted. However, for a folding cart with a large volume, such as a nucleic acid detecting cart, the main supporting surface area is large, and if the folding cart is integrally folded, the largest surface area is large, which is not beneficial to vehicle transportation.
In summary, if the folding frame of the two folding methods is applied to the scene outside life, the following disadvantages generally exist:
(1) The area of the maximum surface is overlarge after folding, which is inconvenient for vehicle transportation.
(2) The bearing capacity is poor, and the application is not suitable for more bearing scenes beyond life.
(3) Folding frames and folding carts with high load-bearing capacity generally cannot be folded and unfolded rapidly by a single person.
