When the vehicle body 100 is in the folded state, the left bracket 140 and the right bracket 150 are folded in the left-right direction, the upper pull rod 171 and the lower pull rod 172 are folded, and the end 173 of the pull rod slides backwards along the bottom connecting rod 113, so that the pull rod assembly 170 is converted to extend in the front-back direction and be folded under the bottom connecting rod 113, and the folded front bracket 120, the rear bracket 130, the chassis 110, the seat assembly 200 and the like are all folded between the left bracket 140 and the right bracket 150, and the whole vehicle is significantly reduced in volume and flat, and is easy to store and transport.

Referring to fig. 1 to 4, in the present embodiment, the seat assembly 200 has two sets disposed on both sides of the seating space 100a in the second direction, which is the front-rear direction of the vehicle body 100. When the vehicle body 100 is in the deployed state, each set of seat assemblies 200 has an open state and a stowed state. When both sets of seat assemblies 200 are in the open position, at least two children can sit and communicate face to face; when both sets of seat assemblies 200 are in the stowed position, the vehicle body 100 has a larger seating space 100a for a child to lie down on, and also for holding items.

In this embodiment, the two sets of seat assemblies 200 have the same structure, and each of the two sets of seat assemblies includes a sitting support for providing a sitting support for a child, and the sitting support is relatively rotatably disposed on the vehicle body 100 about a rotation center line extending in a first direction, where the first direction is parallel to the third direction, which is a left-right direction of the vehicle body 100. In a distinction, the seat assembly 200 includes a first seat assembly 201 disposed on the front side and a second seat assembly 202 disposed on the rear side, wherein the sitting support of the first seat assembly 201 is disposed on the front bracket 120 (or first bracket) so as to be relatively rotatable around a first rotation center line 1001, the sitting support of the second seat assembly 202 is disposed on the rear bracket 130 (or second bracket) so as to be relatively rotatable around a second rotation center line 1002, and the first rotation center line 1001 and the second rotation center line 1002 are parallel to each other and both extend in the left-right direction of the vehicle body 100.

The specific construction of the seat assembly 200 is described below with reference to the first seat assembly 201 as an example. Referring to fig. 8 to 10, in the present embodiment, the sitting support includes two side bars 210 and two cross bars 220, wherein the two side bars 210 are respectively disposed at the left and right sides of the sitting space 100a, the cross bars 220 are connected between the two side bars 210, and one end of each side bar 210 is relatively rotatably disposed on the front bracket 120 around a first rotation center line 1001.

Further, the cross bar 220 includes a first section 221 and a second section 222 respectively disposed at the left and right sides, and when the vehicle body 100 is in the unfolded state, the axial lines of the first section 221 and the second section 222 extend in a co-linear manner in the left and right direction. One end of the first segment 221 adjacent to the second segment 222 is pivotally connected to a third pivot line 1003, the other end of the first segment 221 is pivotally connected to the side bar 210 on the same side about a fourth pivot line 1004, and the other end of the second segment 222 is pivotally connected to the side bar 210 on the same side about a fifth pivot line 1005. In the open state of the seat assembly 200, the third pivot axis 1003, the fourth pivot axis 1004, and the fifth pivot axis 1005 are parallel to each other and extend in the front-rear direction of the vehicle body 100.

Referring to fig. 1 and 2, in the present embodiment, the seat assembly 200 further includes an upright 230 and a sliding member 240, and the upright 230 and the sliding member 240 respectively have two sets disposed at the left and right sides of the seating space 100 a. Wherein, each set of sliding pieces 240 can be arranged on the bottom side rod 112 on the same side in a manner of sliding relatively along the front-back direction. One end of each vertical rod 230 is rotatably connected to the side rod 210 on the same side about a sixth rotation center line 1006, and the other end is relatively rotatably provided to the slider 240 on the same side about a seventh rotation center line 1007. The sixth turning center line 1006, the seventh turning center line 1007 and the first turning center line 1001 are parallel to each other, and when the vehicle body 100 is in the unfolded state, the sixth turning center line 1006 and the axis direction of the cross bar 220 extend in the same line.

In other embodiments, especially when the folding of the vehicle body 100 is not considered, the number of the side bars 210, the vertical bars 230, and the sliding members 240 in each set of the seat assembly 200 is not limited to two left and right sets, and may include only one set disposed in the middle of the sitting support, or multiple sets disposed at intervals in the left and right.

In addition, in order to realize the sitting and standing support, the seat assembly 200 should further include a support member (not shown) such as a cloth pocket, a seat plate, etc. disposed between the side bars 210 and the crossbar 220. When rigid seat plates are provided between the side bars 210 and the crossbar 220, the seat plates may include two groups respectively provided on the left and right sides so as not to interfere with the left and right folding of the seat assembly 200 and the vehicle body 100, each group of seat plates being provided between the crossbar 220 (the first section 221 or the second section 222) and the side bars 210 on the same side, and the two groups of seat plates being disconnected or rotatably connected to each other with a rotation center line extending in parallel or in line with a third rotation center line.

In addition, a locking mechanism for locking the seat assembly 200 in the opened state is further provided between the seat assembly 200 and the vehicle body 100, and the specific structure of the locking mechanism may be the prior art, but the present invention is not limited thereto.

The working principle of the child hand buggy in the embodiment is specifically explained as follows:

Referring to fig. 1 and 2, in the open position of both sets of seat assemblies 200, the first seat assembly 201 and the second seat assembly 202 are spaced apart in the fore-and-aft direction to define a space therebetween for two children to place their legs face-to-face. At this time, for each set of seat assemblies 200, the sitting support extends horizontally in the front-rear direction, each side bar 210 extends in the front-rear direction, the first section 221 and the second section 222 of the crossbar 220 extend in the left-right direction, the sitting support is spaced apart from the bottom of the seating space 100a up and down, and the up-down distance between the side bars 210 and the bottom frame 110 is just equal to the length of the side bars 210 in the front-rear direction, so that the sitting support can be just placed on the bottom frame 110 after being turned down. The upright 230 extends in the up-down direction and is located below the sitting support, and the sliding member 240 is located at the lower end of the upright 230. At the moment, the upper end part of each side bracket is higher than the sitting support piece, so that children can lean against the side bracket, and the periphery of the children is protected.

Referring to fig. 3 and 4, when it is required to convert the seat assembly 200 into the stowed state, it is only necessary to unlock the seat assembly 200 and then press it downward so that the sitting support rotates downward about the rotation center line and is converted to extend in the up-down direction. In the retracted state, each side bar 210 extends in the up-down direction, the cross bar 220 still extends in the left-right direction and descends to the bottom of the seating space 100a, and the sitting support and the side brackets are folded together, wherein the sitting support of the first seat assembly 201 and the front bracket 120 are folded together, and the sitting support of the second seat assembly 202 and the rear bracket 130 are folded together. The vertical rod 230 is rotated about the seventh rotation centerline 1007 to extend in the front-rear direction and converge with the bottom side rod 112.

When the seat assembly 200 in the retracted state needs to be opened, the above steps are reversed, and the sitting support member is lifted up to be horizontal and locked, so that the operation is convenient, and the details are not repeated herein.

Referring to fig. 5 to 7, when the vehicle body 100 is in the folded state, the side bars 210 extend in the front-rear direction, the vertical bars 230 extend in the up-down direction, and the first sections 222 and the second sections 221 respectively extend in the up-down direction and are folded together (when the seat plate is included in the seat assembly 200, the two seat plates also extend in the up-down direction and are folded together), so that the seat assembly 200 can be folded flat in the left-right direction and is folded between the left bracket 140 and the right bracket 150.

In addition, in other embodiments, when the folding structure of the vehicle body 100 is folded back and forth, the structure of the seat assembly 200 in this embodiment is also applicable, and the seat assembly 200 and the vehicle body 100 can be folded together. In addition, the seat assembly 200 of the present embodiment has a complete structure, and the main support rods can be folded without being broken, thereby ensuring the supporting strength for sitting and standing.

Example 2

Referring to fig. 11 to 14, in the present embodiment, the structure of the child hand buggy is substantially the same as that of embodiment 1, and the main difference is that the specific arrangement of the seat assembly 200 is different.

In this embodiment, the sitting support also includes side bars 210 respectively disposed at the left and right sides, and a cross bar 220 disposed between the two side bars 210. However, in this embodiment, the vertical rod 230 and the sliding member 240 are not provided, and each side rod 210 is fixedly provided opposite to the cross rod 220 on the same side.

Specifically, one end of the crossbar 220 adjacent to the first segment 221 and the second segment 222 is rotatably connected around a third rotation center line 1003, while the other end of the first segment 221 is integrally and fixedly arranged with a side bar 210 on the same side, and the side bar 210 is relatively rotatably arranged on the side bracket around a fourth rotation center line 1004; the other end of the second segment 222 is fixed integrally to the side bar 210 on the same side, and the side bar 210 is provided on the side bracket so as to be relatively rotatable around a fifth rotation center line 1005. In the open state of the seat assembly 200, the third pivot axis 1003, the fourth pivot axis 1004, and the fifth pivot axis 1005 are parallel to each other and extend in the front-rear direction of the vehicle body 100.

As such, in the present embodiment, the entire seating support may rotate around the first rotation center line 1001 or the second rotation center line 1002, thereby switching between the open state and the stowed state. When the vehicle body 100 is in the folded state, the side bars 210 on both sides are rotated about the fourth pivot center line 1004 and the fifth pivot center line 1005, respectively, to approach each other, and finally the first section 221 and the second section 222 are converted to extend in the up-down direction and to be folded together.

In addition, in other embodiments, the seating support may include only a seat plate, one end of which is rotatably provided on the side bracket about a rotation center line, and the seat assembly 200 may be converted between the open state and the stowed state.

Example 3

Referring to fig. 15 to 17, in this embodiment, the structure of the stroller is substantially the same as that of embodiment 2, and the main differences are the selection of the first direction and the second direction and the specific arrangement of the seat assembly 200.

In this embodiment, the structure of the vehicle body 100 itself and the folding principle thereof are the same as those of embodiments 1 and 2, and the vehicle body 100 can be folded in the left-right direction (i.e., the third direction).

However, in the present embodiment, the front-rear direction of the vehicle body 100 is set as the first direction, and the left-right direction of the vehicle body 100 is set as the second direction. In this way, the first seat assembly 201 and the second seat assembly 202 are disposed on the left and right sides of the seating space 100a, the left bracket 140 can be regarded as a first bracket, the right bracket 150 can be regarded as a second bracket, the sitting support of the first seat assembly 201 is disposed on the left bracket 140 so as to be relatively rotatable about the first rotation center line 1001, the sitting support of the second seat assembly 202 is disposed on the right bracket 150 so as to be relatively rotatable about the second rotation center line 1002, and the first rotation center line 1001 and the second rotation center line 1002 are parallel to each other and both extend in the front-rear direction of the vehicle body 100.

In this embodiment, each set of sitting support member includes two side rods 210 respectively disposed at the front and rear sides, and a cross rod 220 fixedly disposed between the two side rods 210. Also, since the seat assembly 200 itself does not need to be folded laterally, the crossbar 220 is not divided into the first and
