In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0053] The embodiment provides a carrier for carrying children and improves the flexibility of children riding and enhances the use flexibility and use experience of the carrier.

[0054] Specifically, as shown in Figures 1 to 6 The carrier comprises two end supports 2 arranged oppositely and spaced apart in a first direction and a support mechanism 1 connected between the two end supports 2, the support mechanism 1 and the two end supports 2 surround to form an accommodation space, and the support mechanism 1 has at least two modes to adjust the length of the accommodation space in the first direction. At least one end of the carrier is movably connected with an expansion assembly 3, and the expansion assembly 3 can be unfolded outward relative to the end support 2 to form an expansion space with variable volume with the end support 2, and the expansion space is in communication with the accommodation space.

[0055] The carrier provided by the embodiment can adjust the length of the accommodation space in the first direction by changing the mode of the support mechanism 1, so that the accommodation space can be adjusted to meet the needs of one child riding or two children riding, or to meet the needs of accommodating children or articles of different sizes, thereby improving the use flexibility and reliability of the carrier. At the same time, by arranging the expansion assembly 3, and the expansion assembly 3 can be unfolded outward relative to the end support 2 to increase the expansion space, the expansion demand of the carrier can be met on the basis that the structure of the support mechanism 1 is unchanged, and the use experience of the carrier is further improved.

[0056] To meet the moving demand of the carrier, the lower end of each of the two end supports 2 is provided with a mobile caster 6. Further, each end support 2 is provided with a mobile caster 6 on both sides in the second direction to improve the stability of the carrier movement. In other embodiments, one of the end supports 2 can be provided with a mobile caster 6, and the other end support 2 can be provided with two mobile casters 6. The specific structure of the mobile caster 6 can be set according to the prior art, which is not the focus of the present application, and will not be described here.

[0057] The first direction and the second direction are perpendicular to each other and are both horizontal directions, and the vertical direction is the third direction.

[0058] For the convenience of subsequent description, the two end supports 2 are referred to as first support 2a and second support 2b, respectively, and the expansion assembly 3 is installed on the second support 2b. The two mobile casters 6 installed on the lower end of the first support 2a are first casters 6a, and the two mobile casters 6 installed on the lower end of the second support 2b are second casters 6b.

[0059] To simplify the structure of the carrier, the end support 2 includes end longitudinal rods 21 arranged opposite and spaced apart in the second direction and an end top cross rod 23 connected between the top ends of the two end longitudinal rods 21, and each end longitudinal rod 21 is connected with a mobile caster 6. The lower ends of the two end longitudinal rods 21 are also connected by an end bottom cross rod 22 to improve the overall structural strength and rigidity of the entire end support 2. The structure of this kind of end support 2 is simple and easy to process. The two end longitudinal rods 21 and the end top cross rod 23 are integrally bent and formed by rod-shaped metal rods.

[0060] The accommodation space includes at least two accommodation subspaces arranged in sequence in the first direction, and the support mechanism 1 can be partially unfolded or folded in the first direction to adjust the length of at least one accommodation subspace, so as to adjust the length of the accommodation space in the first direction by adjusting the length of the accommodation subspace, and thus the carrier can meet the seating demand of one or two children.

[0061] In the present embodiment, the accommodation subspaces are provided with two, which can meet the seating of two children when both of the two accommodation subspaces have the maximum length, can meet the seating of one child when one of the two accommodation subspaces has the minimum length and the other has the maximum length, and the carrier is in the storage state when both of the two accommodation subspaces have the minimum length.

[0062] That is, in the present embodiment, the support mechanism 1 has three states of a fully unfolded state, a half-folded state and a fully folded state, when the support mechanism 1 is in the fully unfolded state, both of the accommodation subspaces have the maximum length, and the carrier is in the first use state; when the support mechanism 1 is in the half-folded state, one of the accommodation subspaces has the maximum length, and the other has the minimum length, and the carrier is in the second use state; when the support mechanism 1 is in the fully folded state, both of the accommodation subspaces have the minimum length, and the carrier is in the storage state. Such a setting can better meet the use requirements of the carrier while reducing the overall size and overall structural complexity of the carrier.

[0063] In other embodiments, the accommodation subspaces can be provided with two or more, and the length of part of the accommodation subspaces in the first direction can be adjusted, or the length of all the accommodation subspaces in the first direction can be adjusted.

[0064] In the present embodiment, the two adjacent accommodation subspaces are communicatively connected to improve the comfort of children riding in the accommodation subspaces and better meet the riding requirements of children with larger body sizes. In other embodiments, the two adjacent accommodation subspaces can be separated by a separation structure, which can be a hard rail structure, a soft cloth structure or other structures, etc.

[0065] In the present embodiment, the support mechanism 1 includes an intermediate support 11 and two folding assemblies 12 connected between the intermediate support 11 and the two end supports 2, respectively, and the folding assembly 12, the intermediate support 11 and the corresponding end support 2 form an accommodation subspace therearound. Each folding assembly 12 can be folded or unfolded along the first direction to adjust the length of the accommodation subspace. Such a setting allows the length of each accommodation subspace to be adjusted individually, thereby further improving the adjustment flexibility of the accommodation space and the use flexibility of the carrier.

[0066] In other embodiments, the at least two accommodation subspaces arranged side by side are adjusted in sequence. Taking the case where the two accommodation subspaces are provided with two, the two accommodation subspaces are a first subspace and a second subspace, respectively, when both of the two accommodation subspaces are in the maximum length, only the first subspace can be adjusted first, and when the first subspace is adjusted to the minimum length, the second subspace can be adjusted; at the same time, when both of the two accommodation subspaces are in the minimum length, only the first subspace can be unfolded to the maximum length, and then the second subspace can be unfolded.

[0067] Each folding component 12 has an unfolded state and a folded state. When the folding component 12 is in the folded state, the intermediate support 11 closes with the corresponding end support 2. When the folding component 12 is in the unfolded state, the accommodating subspace has its maximum length. This ensures that when the folding component 12 is in the folded state, there is a minimum gap between the end support 2 and the intermediate support 11, reducing the size of the folding component 12 after folding.

[0068] That is, when both folding components 12 are in the unfolded state, the support mechanism 1 is in the fully unfolded state; when one folding component 12 is in the unfolded state and the other folding component 12 is in the folded state, the support mechanism 1 is in the half-folded state; when both folding components 12 are in the folded state, the support mechanism 1 is in the fully folded state.

[0069] In this embodiment, the folding assembly 12 includes a folding base frame 121 and a side folding rod assembly 122. The folding base frame 121 is connected between the bottom of the intermediate support 11 and the bottom of the end support 2, and the side folding rod assembly 122 is connected between the intermediate support 11 and the end support 2 on corresponding sides in a second direction. Both the folding base frame 121 and the side folding rod assembly 122 are foldable so that the intermediate support 11 and the end support 2 are brought closer together. By setting the folding base frame 121, stable support for children within the accommodating space can be achieved, improving the stability of the child-carrying vehicle. By setting the side folding rod assembly 122, lateral restraint for children within the accommodating sub-space can be provided, improving the safety and stability of the child-carrying vehicle, and also improving the overall structural stability of the vehicle.

[0070] In another embodiment, only the folding base frame 121 may be provided, while the accommodating subspace is stopped on opposite sides in the second direction by flexible fabric, flexible mesh, or other structures. In yet another embodiment, the folding assembly 12 may include side folding rods 122, and the bottom of the accommodating space is supported by flexible fabric.

[0071] In this embodiment, the end bracket 2 is connected to the corresponding side of the intermediate bracket 11 via side folding rod assemblies 122 on both sides along the second direction, thereby improving the overall structural stability of the vehicle and enhancing the child protection effect. In other embodiments, the side folding rod assemblies 122 can be provided only on one side of the end bracket 2, while the other side can be protected by a flexible fabric or netting or other protective structure to protect the child within the accommodating space.

[0072] Furthermore, a barrier structure is provided between the folding base frame 121 and the side folding rod assembly 122 to prevent children from falling out of the storage space, thereby improving the safety and reliability of the vehicle.

[0073] To simplify the vehicle's structure, the intermediate support 11 includes two intermediate support rods 111 that are positioned opposite each other and spaced apart in the second direction. The intermediate support rods 111 extend vertically, and the folding base frame 121 connects the two intermediate support rods 111 and the end support 2. Side folding rod assemblies 122 connect the corresponding intermediate support rods 111 and the end support 2. Specifically, the side folding rod assemblies 122 connect the intermediate support rods 111 and the corresponding end longitudinal rods 21. The two end longitudinal rods 21 and the intermediate support rods 111, located between the two ends and on the same side, are situated in the same plane.

[0074] In this embodiment, the folding base frame 121 includes two bottom folding rod groups that are opposite to each other and spaced apart in a second direction. Each bottom folding rod group includes two bottom support rods 1211. The first ends of the two bottom support rods 1211 are hinged relative to each other around a first axis. The second ends of the two bottom support rods 1211 are respectively hinged to the end bracket 2 and the intermediate bracket 11. A support crossbar 1212 is connected between the two bottom support rods 1211 connected to the end bracket 2 and / or between the two bottom support rods 1211 connected to the intermediate bracket 11. The hinge axes at both ends of each bottom support rod 1211 are arranged along the second direction.

[0075] The structure of this folding base frame 121 achieves folding and unfolding by setting two hinged bottom support rods 1211. By setting a support crossbar 1212, the support crossbar 1212 becomes the bottom support of the accommodating subspace, and the two bottom folding rod groups are connected, thereby realizing the synchronous unfolding and folding of the two bottom support rod groups on both sides, improving the folding stability and reliability of the bottom folding base frame 121.

[0076] Furthermore, a hinge portion is provided on the inner side of the end longitudinal rod 21, and the second end of the bottom support rod 1211 is hinged to the hinge portion, so that the folding base frame 121 is located between the two end longitudinal rods 21, avoiding the folding base frame 121 protruding from the end bracket 2 in the second direction and causing scratches. The intermediate support rod 111 includes a rod body 1111 and a lower hinge joint 1112 connected to the lower end. The width of the lower hinge joint 1112 in the first direction is greater than the width of the rod body 1111. The corresponding bottom support rod 1211 is hinged to the lower hinge joint 1112, and the two support bottom rods on both sides of the intermediate support rod 111 are hinged to the two ends of the lower hinge joint 1112.

[0077] To further simplify the structure of the folding base frame 121, the support crossbar 1212 and the bottom support rods 1211 at both ends are integrally bent from metal rods to reduce the processing difficulty of the folding base frame 121.

[0078] For ease of description, the bottom support rod 1211 connected to the support crossbar 1212 is referred to as the first bottom rod, and the other two bottom support rods 1211 are referred to as the second bottom rods. That is, each bottom folding rod assembly includes a first bottom rod and a second bottom rod, which are hinged together. The second bottom rod is hinged to the side of the first bottom rod opposite to the other bottom folding rod assembly to avoid interference with the support crossbar 1212.

[0079] When the first and second base rods rotate to the horizontal position, the accommodating subspace has its maximum length. When the first and second base rods rotate to be close together, the accommodating subspace has its minimum length, and the hinge position of the first and second base rods is raised upward to avoid interference with the ground.

[0080] Furthermore, rotation limiting members 1213 are connected to the upper sides of both ends of the support crossbar 1212 along the second direction. When the folding base frame 121 is unfolded to the horizontal, the rotation limiting members 1213 abut against the upper side of the bottom support rod 1211 that is not connected to the support crossbar 1212, thereby restricting the two bottom support rods 1211 on the same side from further rotation and ensuring that the bottom folding rod assembly is stably in the unfolded position. The rotation limiting members 1213 are preferably welded or screwed to the upper side of the support crossbar 1212, and the rotation limiting members 1213 extend along the second direction to simplify the structure of the rotation limiting members 1213.

[0081] In this embodiment, each side-folding rod assembly 122 includes two side rails 1221. The first ends of the two side rails 1221 are hinged relative to each other around a second axis, and the second ends of the two side rails 1221 are respectively hinged to the end bracket 2 and the intermediate bracket 11. The hinge axes between the two side rails 1221 and the hinge axes between the side rails 1221 and the end bracket 2 and the intermediate bracket 11 are all arranged along the second direction. Thus, the two side rails 1221 can be rotated out to a flush position and rotated closed. Furthermore, when the two side rails 1221 are closed relative to each other, the first ends of the two side rails 1221 move downward to avoid the upper ends of the side rails 1221 protruding upward, which would result in a large height of the vehicle after storage.

[0082] Furthermore, the two side rails 1221 are hinged by a rotating joint, and the rotating joint restricts the first end of the two side rails 1221 from moving upward to close. The rotating joint and the connection structure between the rotating joint and the side rail 1221 can be set with reference to the existing rotating connection structure between two rods. In this embodiment, no specific limitation is made on the rotating connection structure between the two side rails 1221.

[0083] Furthermore, the intermediate support rod 111 also includes an upper hinge joint 1113 connected to the upper end of the rod body 1111. The length of the upper hinge joint 1113 along the first direction is greater than the length of the rod body 1111 along the first direction. The side rails 1221 on both sides of the intermediate support rod 111 are hinged to the upper hinge joint 1113.

[0084] When the end bracket 2 and the middle bracket 11 approach each other, the first axis moves upward and the second axis moves downward to avoid interference between the folding base frame 121 and the ground, and at the same time to prevent the height of the folding assembly 12 from increasing after folding. To avoid interference, in this embodiment, the first axis and the second axis are opposite to each other and spaced apart in the first direction, and both the first axis and the second axis extend along the second direction. This allows the connecting ends of the two side rails 1221 and the two ends of the two bottom support rods 1211 to be misaligned in the first direction when the folding assembly 12 is folded, thereby reducing the probability of interference.

[0085] In other embodiments, the two bottom support rods 1211 on the same side may rotate relative to each other around a first axis, and the two side rails 1221 on the same side may rotate relative to each other around a second axis. The first axis and the second axis may extend in different directions so that the folding base frame 121 and the side folding rod group 122 may interfere with each other when folding.

[0086] like Figure 1 , Figure 4 and Figure 7 As shown, in this embodiment, the vehicle further includes a connecting component 5, which includes a cooperating first connector 51 and a second connector 52. Specifically, the end bracket 2 is provided with the first connector 51, and the middle bracket 11 is provided with the second connector 52. When the folding component 12 is in the folded state, the first connector 51 and the second connector 52 are detachably connected. By providing the first connector 51 and the second connector 52, the folding component 12 can be stably maintained in the folded state, preventing the folding component 12 from being arbitrarily unfolded and causing bumps or collisions to users or objects, thereby improving the stability and reliability of the vehicle.

[0087] In this embodiment, the first end of the first connector 51 is rotatably mounted on the end bracket 2. When the folding assembly 12 is in the folded state, the second end of the first connector 51 is hooked or snapped onto the second connector 52. This arrangement allows the first connector 51 and the second connector 52 to be disengaged or connected by rotating the first connector 51, improving the ease of disassembly of the first connector 51 and the second connector 52, and thus improving the ease of operation for folding and unfolding the vehicle.

[0088] In other embodiments, one end of the second connector 52 may be rotatably connected to the intermediate bracket 11, and when the folding assembly 12 is in the folded state, the second end of the second connector 52 may be hooked or snapped onto the first connector 51.

[0089] In this embodiment, each end bracket 2 is provided with a first connector 51 on both sides along the second direction, and the middle bracket 11 is provided with a second connector 52 on both sides along the second direction, thereby ensuring the connection stability between the middle bracket 11 and the corresponding end bracket after the folding assembly 12 is folded. Furthermore, the first connectors 51 respectively provided on the two end brackets 2 and on the same side are connected to the same second connector 52, that is, a second connector 52 is provided on each side of the middle bracket 11 along the second direction, to reduce the number of components in the carrier and lower costs.

[0090] The second connector 52 is a protruding column structure protruding on the intermediate support 11. The first connector 51 is a long strip structure, and a hook groove 511 is provided on the lower side of the second end of the first connector 51. When the first connector 51 is rotated to the horizontal, the second connector 52 is inserted into the hook groove 511.

[0091] In other embodiments, the first connector 51 and the second connector 52 may also employ other structures such as buckles, ties, or magnets to stably hold the folding assembly 12 in a folded state.

[0092] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the expansion assembly 3 includes a main stop 31, the lower end of which is connected to the end bracket 2 or the support mechanism 1. In this embodiment, the lower end of the main stop 31 is hinged to the end bracket 2, allowing the upper end of the main stop 31 to move closer to or further away from the end bracket, thereby adjusting the space between the end bracket 2 and the main stop 31. This method facilitates the unfolding or folding of the expansion assembly 3, thereby improving the operational convenience of the vehicle and reducing the space occupied by the expansion assembly 3.

[0093] In another embodiment, the main stop 31 is slidably connected to the end bracket 2, thereby allowing the main stop 31 to slide closer to or further away from the end bracket 2 to adjust the size of the expansion space. In yet another embodiment, the main stop 31 is detachably connected to the end bracket 2, and the mounting position of the main stop 31 on the end bracket 2 is adjustable along a first direction, thereby adjusting the position between the main stop 31 and the end bracket 2, and thus adjusting the size of the expansion space.

[0094] The expansion assembly 3 also includes side baffles 32 connected to opposite sides of the main baffle 31. The side baffles 32 are connected to the end brackets 2, and the length of the side baffles 32 connected between the main baffle 31 and the end brackets 2 is adjustable. The main baffle 31, the end brackets 2, and the two side baffles 32 together form an expansion space, and items within the expansion space are allowed to fall out due to the placement of the side baffles 32.

[0095] In this embodiment, the main stop 31 includes a frame and a side panel or baffle covering the frame to simplify the structure. In other embodiments, the main stop 31 can be a plate-like structure. The main stop 31 can be rotated to a horizontal position so that it can directly support items. In other embodiments, the maximum included angle between the main stop 31 and the end bracket 2 can be an acute angle.

[0096] The side guard component 32 is preferably a flexible structure to facilitate its telescopic adjustment, thereby enabling the expansion assembly 3 to be unfolded or folded. Exemplarily, the side guard component 32 includes a strap connecting the flip-up baffle and the upper part of the end bracket 2, and its length is adjustable. In other embodiments, the side guard component 32 may also include other structures capable of preventing items from falling and capable of unfolding or folding, such as flexible ropes or flexible fabric.

[0097] In this embodiment, in order to further reduce the space occupied by the vehicle when it is stored, the main stop 31 can be rotated to be accommodated inside the end bracket 2, thereby ensuring that the expansion component 3 will not protrude from the end bracket 2 when folded, thereby reducing the space occupied by the vehicle.

[0098] Specifically, the frame has a U-shaped structure and has two first rods arranged opposite each other in a second direction and a second rod connecting the upper ends of the two first rods. The lower end of the first rod is hinged to the adjacent end longitudinal bar 21. When the main stop 31 is rotated to be accommodated in the end bracket 2, the second rod is positioned directly opposite the end top crossbar 23.

[0099] To further improve the ease of use of the vehicle, a tow rod assembly 4 is movably connected to the first bracket 2a. The tow rod assembly 4 is used by the user to tow the vehicle, thereby improving the ease of vehicle movement. The lower end of the tow rod assembly 4 is hinged to the end bracket 2, and the hinge axis is set along the second direction, so that the tow rod assembly 4 can move closer to or away from the first bracket 2a around its hinge axis. Thus, when the vehicle needs to be moved, the tow rod can be unfolded at a certain angle relative to the first bracket 2a to improve the ease of pushing and pulling the vehicle. When the user does not need to use the vehicle, the tow rod assembly 4 can be brought closer to the first bracket 2a, thereby reducing the size of the vehicle in the first direction and improving the ease of storage of the vehicle. Furthermore, the lower end of the tow rod assembly 4 is rotatably mounted to the end bottom crossbar 22 of the first bracket 2a.

[0100] Furthermore, the tow bar assembly 4 has a telescopic structure that adjusts the length of the tow bar assembly 4, thereby reducing the vehicle's dimensions in the height direction. It also allows users to adjust the upper position of the tow bar assembly 4 according to their own height, improving the ease of use of the tow bar assembly 4 and thus improving the ease of use of the vehicle.

[0101] In this embodiment, the tow rod assembly 4 includes an adjusting rod assembly 41 and a handle 42. The adjusting rod assembly 41 is provided with an adjusting structure and its lower end is hinged to the first bracket 2a. The adjusting rod assembly 41 extends from bottom to top. The handle 42 extends along the second direction and its middle part along the length direction is connected to the upper end of the adjusting rod assembly 41, so as to facilitate the user to hold the tow rod assembly 4.

[0102] It is understood that the specific structure of the tow bar assembly 4 can be set with reference to the existing technology, which is not the focus of this utility model and will not be described in detail here.

[0103] like Figure 8 As shown, when the vehicle is in its first usage state (e.g.) Figure 8 (a) As shown in the figure, the two telescopic components are in the extended state, the support mechanism 1 is in the fully extended state, the accommodating space has the maximum length in the first direction, and there is an acute angle between the towing rod group 4 and the first bracket 2a.

[0104] When it is necessary to store or reduce the storage space, one of the folding components 12 can be switched to a folded state, such as... Figure 8 (b) and Figure 8 As shown in (c), the corresponding end bracket 2 and the middle bracket 11 move closer to each other, the support crossbar 1212 of the folding base frame 121 rises upward, and the first section of the two side rails 1221 closes downward.

[0105] When the folding component 12 is switched to the folded state, as follows: Figure 8 (c) and Figure 8 As shown in (d), the first connector 51 on the corresponding end bracket 2 is rotated to connect with the second connector 52 so that the folding assembly 12 maintains a stable folded state.

[0106] When further storage of the vehicle is required, such as Figure 8 As shown in (e), another folding assembly 12 is switched to a folded state so that the other end bracket 2 and the middle bracket 11 come together in the first direction;

[0107] When the folding component 12 transitions to the folded state, such as Figure 8 As shown in (f), the first connector 51 on the corresponding end bracket 2 is rotated to connect with the second connector 52;

[0108] The four tow bar components are retracted to reduce the overall length of the tow bar assembly, such as... Figure 8 (g) is shown;

[0109] Finally, bring the four pieces of the tow bar assembly closer to the first bracket 2a, as follows: Figure 8 As shown in (h), this allows the entire vehicle to have a smaller storage size.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
