The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 8, the present application provides a cart having an unfolded state and a folded state, which includes two symmetrically arranged side frames 100, a basket 200, and a strut set. The side frame 100 has opposite front and rear sides, and front and rear wheels are mounted on the bottom of the side frame 100 to perform the movement, respectively.

The basket 200 is installed between the two side frames 100, and includes an annular frame 210 and a flexible bag 220 connected to the annular frame 210 to form an accommodating space, which can be used for storing articles, pets, children, etc., and the flexible bag 220 is convenient for the cart to be deformed when folded.

The connection between the side frame 100 and the annular frame 210 is described in detail below, where the side frame 100 includes a front leg 101, a rear leg 102, a lower handle 103, an upper handle 104 and a side bar 105, where the upper handle 104 and the lower handle 103 together form a handle, the top of the front leg 101 is hinged to the top of the rear leg 102, the bottom of the lower handle 103 is hinged to the rear leg 102, the upper handle 104 is hinged to the lower handle 103, and two ends of the side bar 105 are hinged to the top of the rear leg 102 and the bottom of the upper handle 104, respectively. The support rod group comprises a first support rod 310 and a second support rod 320, one end of the first support rod 310 is hinged with the lower handle rod 103, the other end of the first support rod 310 is hinged with the annular frame 210, one end of the second support rod 320 is hinged with the side rod 105, the other end of the second support rod 320 is hinged with the lower handle rod 103, and the annular frame 210 is hinged with the second support rod 320.

In the folding process, the upper handle bar 104 serves as a driving rod and rotates relative to the lower handle bar 103 to further drive the side bars 105 and the annular frame 210 to rotate and draw close to the rear foot bar 102, a linkage is arranged between the front foot bar 101 and the rest of the bar members or other transmission mechanisms are used for synchronously rotating and drawing close to the rear foot bar 102, the front foot bar 101 is positioned on the front side of the rear foot bar 102 in the folding state, and the upper handle bar 104, the lower handle bar 103, the side bars 105 and the annular frame 210 are positioned on the rear side of the rear foot bar 102.

The trolley of the application, the annular frame 210 is hinged to the first support rod 310 and the second support rod 320 of the support rod group, so that the basket 200 can be arranged higher, the accommodating space is larger, and the universality is stronger.

The specific hinge position of the second brace 320 will be explained below. As shown in fig. 1 to 2, the upper handle bar 104 and the lower handle bar 103 are hinged to the first hinge point 106, the upper handle bar 104 and the side bar 105 are hinged to the second hinge point 107, and two ends of the second stay 320 are respectively hinged to the first hinge point 106 and the second hinge point 107. Of course, in order to increase the accommodating space of the basket 200 as much as possible, the hinge point between the second brace 320 and the annular frame 210 is disposed at the top of the side bar 105, and at this time, the basket 200 is highest relative to the ground, i.e. the accommodating space is largest.

When the accommodating space is large, the more articles can be carried, the heavier the weight can be correspondingly carried, and the flexible containing bag 220 has a certain upper bearing limit, so as to avoid the situation that the flexible containing bag 220 is broken due to the overweight of the carried articles, the basket 200 includes a bottom support frame 230 for providing a supporting function, in an unfolded state, the bottom support frame 230 and the annular frame 210 are in two approximately parallel horizontal planes, and the bottom support frame 230 is positioned right below the annular frame 210.

In one embodiment, a two-fold bar 108 is disposed between the front leg 101 and the rear leg 102, the side frame 100 includes a linkage 109 having one end hinged to the side bar 105 and the other end hinged to the two-fold bar 108, and the bottom bracket 230 is hinged to the linkage 109 and the lower handle bar 103. Specifically, the linkage 109 is hinged to a hinge point of the two-fold bar 108, and during the unfolding/folding process, the linkage 109 acts on the hinge point to move the two-fold bar 108. The linkage 109 has a bending section 110 hidden inside the side bar 105, so that it can be folded to avoid the lower handle bar 103 to interfere.

As shown in fig. 1 and 4, the bottom bracket 230 includes two U-shaped rods 231, one of which is provided at both ends with a connecting rod 232 that is inserted into and engaged with the other. In order to improve the structural strength of the joint between the connecting rod 232 and the U-shaped rod 231, the connecting member 234 hinged to the lower handle bar 103 is provided at this position, the number of the connecting members 234 is 2, and each connecting member 234 is connected to one end of each of the two U-shaped rods 231. Of course, in order to further increase the structural strength of the bottom bracket 230, the U-shaped rod 231 is further provided with a reinforcing rod 235 connected with the U-shaped rod 231 at two ends.

Of course, the annular frame 210 may be further provided with a awning assembly 240 according to requirements, and as shown in fig. 1 and fig. 5 to 6, the awning assembly 240 includes two fixing bases 241 arranged in the middle of the annular frame 210 and arc-shaped stay bar sets 242 with two ends connected with the fixing bases 241. The arc-shaped stay bar group 242 comprises a fixed stay bar 243 and two movable stay bars 244 with end portions rotatably connected with the fixed seat 241, a sunshade cloth 245 is arranged between the adjacent arc-shaped stay bars, the two movable stay bars 244 are located on two sides of the fixed stay bar 243, the awning assembly 240 has a folding state that the movable stay bars 244 are close to the fixed stay bar 243 and a spreading state that the movable stay bars 244 are close to the annular frame 210, and a user can flexibly use the movable stay bars 244 on two sides to realize sunshade according to requirements. In order to facilitate the fixation, a protrusion 256 is disposed at the middle position of each movable stay 244, the annular frame 210 is provided with a snap-fit element 257 matched with the protrusion 256, when the sun is needed, the protrusion 256 of the movable stay 244 is matched with the snap-fit element 257 to shade the sun, and when the sun is not needed, the movable stay 244 is moved close to the fixed stay 243 by releasing the snap-fit relationship between the movable stay 244 and the annular frame 210.

In order to maintain the cart in the unfolded position, one of the upper handle bar 104 and the side bar 105 is provided with a locking groove (invisible in the assembled position), and the other is movably provided with a locking pin (invisible in the assembled position) which is matched with the locking groove, and an elastic member (invisible in the assembled position) which drives the locking pin to extend into the locking groove to maintain the cart in the unfolded position. The resilient member is typically a spring. Wherein, the hinged part between the upper handle bar 104 and the side bar 105 is provided with an elastic reset piece (such as a torsion spring) for driving the handcart to be unfolded, thereby assisting the unfolding, and being rapid and labor-saving.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.
