[0036] See also Figure 1 to Figure 6 The present application provides a carrying device 1000, including a frame having an unfolded state and a folded state, the frame including two oppositely arranged side frames 100 with wheels 101, a support frame 200, a lining 300 (indicated by dotted lines in the figure) and a push handle assembly 400, and the two side frames 100 are arranged relatively spaced apart. The support frame 200 includes a front portion 210 and a rear portion 220 rotatably connected to the side frames 100, and the front portion 210 and the rear portion 220 have an unfolded state in which they are roughly in the same horizontal plane, and a folded state in which they are rotated toward the side frames 100. The lining 300 is flexible and is arranged in the frame to form a loading space, and the loading space can be loaded with articles or infants. Specifically, the lining 300 and the frame are combined in a manner such as being mounted on the support frame 200 and placed between the two side frames 100. When the support frame 200 is folded, the lining 300 is folded synchronously with the support frame 200 until the front portion 210 and the rear portion 220 are in a folded state. Compared with the load-bearing device in the unfolded state, the length dimension is reduced, so that the size of the folded load-bearing device is more suitable for packaging, transportation and storage. In the figure, the wheel 101 includes a front wheel arranged at the bottom of the front side support assembly 110, and a rear wheel arranged at the bottom of the rear side support assembly 120.

[0037] The handle assembly 400 is rotatably connected to the side frame 100, and can be folded and rotated to move closer to the side frame, and can be unfolded and rotated to operate the mobile carrying device. A connecting piece can be set between the two side frames 100, and the connecting piece can be folded or contracted to allow the two side frames to move closer to each other, further reducing the volume of the carrying device in the folded state. In one embodiment, the front part 210 and the rear part 220 can be U-shaped structures.

[0038] Each side frame 100 includes a front side support assembly 110 and a rear side support assembly 120. The bottom support assembly 130 includes a front frame 131 and a rear frame 132 that are rotatably connected. The front frame 131 is rotatably connected to the bottom of the front side support assembly 110, and the rear frame 132 is rotatably connected to the bottom of the rear side support assembly 120. The front side support assembly 110 and the rear side support assembly 120 are rotatably connected at the top. In the folded state, the front side support assembly 110 and the rear side support assembly 120 rotate together, and the front frame 131 and the rear frame 132 are folded in half and located between the front side support assembly 110 and the rear side support assembly 120, further reducing the length of the load-bearing device. Among them, the push handle assembly 400, the front side support assembly 110 and the rear side support assembly 120 are coaxially hinged.

[0039] In one embodiment, the front side support assembly 110 includes a front diagonal rod 112 and a first joint seat 161 disposed at the top of the front diagonal rod, and the rear side support assembly 120 includes a rear diagonal rod 122 and a second joint seat 162 disposed at the top of the rear diagonal rod, and the first joint seat 161 and the second joint seat 162 are pivotally connected to form a central joint 163. Among them, the push handle assembly is pivotally connected at the central joint 163, and a locking mechanism for keeping the push handle assembly 400 in an unfolded state is disposed between the push handle assembly and the central joint 163, and an unlocking member for unlocking the locking mechanism is disposed on the push handle assembly so that the push handle assembly can be rotated close to one of the side support assemblies; or the push handle assembly itself slides or folds to unlock the locking mechanism. In one embodiment, an adapter seat for combining an expansion device is disposed on the inner side of the central joint 163, and the expansion device is, for example, a dining tray, a seat for children to sit on, or an accessory such as a parasol.

[0040] In order to keep the side frame 100 in the unfolded state, a locking mechanism may be provided at a hinge position in the side frame 100, and the locking mechanism is preferably provided at the hinge position of the front frame 131 and the rear frame 132. Alternatively, in another embodiment, a one-way limiting mechanism is provided between the front frame 131 and the rear frame 132, and in the folded state, the hinge position of the front frame 131 and the rear frame 132 moves downward, and in the unfolded state, the front frame 131 and the rear frame 132 are maintained in a horizontal state by the one-way limiting mechanism. In the unfolded state, the bottom support assembly 130, the front side support assembly 110 and the rear side support assembly 120 are roughly triangular, wherein as shown in FIG. Figure 8 As shown, the bottom support assembly 130 includes side bars 133 and a transverse connecting rod 134 disposed between the side bars 133. The side bars 133 include a front section and a rear section that are hinged to each other, and the front section and the rear section correspond to the parts where the front frame 131 and the rear frame 132 are located. It should be noted that the extension direction of the transverse connecting rod 134 is not limited to extending along the width direction, and can also be inclined at a certain angle relative to the width direction, but it must be connected between the two side bars 133.

[0041] In one embodiment, a locking mechanism for keeping the support frame 200 in an unfolded state is provided at the hinged positions of the front portion 210 and the rear portion 220 and the side frame 100 .

[0042] In another embodiment, the front portion 210 is linked to the front side support assembly 110, and the rear portion 220 is linked to the rear side support assembly 120. For example, a front linking member 140 is provided between the front portion 210 and the front side support assembly 110, and the two ends of the front linking member 140 are rotatably connected to the front portion 210 and the front side support assembly 110, respectively. A rear linking member 150 is provided between the rear portion 220 and the rear side support assembly 120, and the two ends of the rear linking member 150 are rotatably connected to the rear portion 220 and the rear side support assembly 120, respectively. The front and rear linking members may be composed of one or more rods as shown in the figure. Specifically, during the unfolding process of the bearing device, the front side support assembly 110 and the rear side support assembly 120 push the front portion 210 and the rear portion 220 respectively through the corresponding linking members to unfold them.

[0043] In one embodiment, the top of the front side support assembly 110 has a first connection portion 111 extending to the rear side, and the end of the rear portion 220 is rotatably connected to the first connection portion 111. The top of the rear side support assembly 120 has a second connection portion 121 extending to the front side, and the end of the front portion 210 is rotatably connected to the second connection portion 121. When unfolding, the ends of the front portion 210 and the rear portion 220 connected to the corresponding connection portions move downward, and the parts connected to the front and rear linkages move upward, so that the front portion 210 and the rear portion 220 are unfolded.

[0044] Among them, the front side support assembly 110 also includes a front diagonal rod 112 connected to the first connecting part 111. In the unfolded state, the front diagonal rod 112 extends obliquely upward, and the first connecting part 111 extends upward or downward and has an extension trend different from that of the front diagonal rod 112. There is an inflection point between the two, which is above or below the hinge position of the front side support assembly 110 and the rear side support assembly 120.

[0045] Similarly, the rear side support assembly 120 also includes a rear diagonal rod 122 connected to the second connecting portion 121. In the unfolded state, the rear diagonal rod 122 extends obliquely upward, and the second connecting portion 121 extends upward or downward and has an extension trend different from that of the rear diagonal rod 122. There is an inflection point between the two, which is above, below or at the same level as the hinge position of the front side support assembly 110 and the rear side support assembly 120.

[0046] In one embodiment, the portion where the rear portion 220 is rotatably connected to the first connection portion 111 is located outside the rear side support assembly 120 , and the portion where the front portion 210 is rotatably connected to the second connection portion 121 is located outside the front side support assembly 110 .

[0047] like Figure 7The present application also provides a bearing device 1000, comprising a frame having an unfolded state and a folded state, the frame comprising two oppositely arranged side frames 100, a support frame 200, a bottom support assembly 130 and a lining 300 (indicated by dotted lines in the figure), the two side frames 100 are arranged relatively spaced apart, each side frame 100 comprises a front side support assembly 110 and a rear side support assembly 120, the bottom support assembly 130 comprises a front frame 131 and a rear frame 132 which are rotatably connected, the front frame 131 is rotatably connected to the bottom of the front side support assembly 110, the rear frame 132 is rotatably connected to the bottom of the rear side support assembly 120, and the front side support assembly 110 and the rear side support assembly 120 are rotatably connected at the top. The support frame 200 comprises a front portion 210 and a rear portion 220 which are rotatably connected to the side frames 100, the front portion 210 and the rear portion 220 have an unfolded state in which they are approximately in the same horizontal plane, and a folded state in which they are rotated toward the front side support assembly 110 and the rear side support assembly 120, respectively. The lining 300 is flexible and is arranged in the frame to form a loading space, which can be used to load articles or carry infants. Specifically, the lining 300 and the frame are combined in such a way that, for example, the lining 300 is mounted on the support frame 200 and placed between the two side frames 100. When the support frame 200 is folded, the lining 300 is folded synchronously with the support frame 200 until the front portion 210 and the rear portion 220 are in a folded state. Compared with the load-bearing device in the unfolded state, the length dimension is reduced, so that the size of the folded load-bearing device is more suitable for packaging, transportation and storage.

[0048] Compared with the existing structure, the carrying device of the present application has a reduced length, so that the size of the folded carrying device is more suitable for packaging, transportation and storage.

[0049] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0050] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
