[0055] Example 1

[0056] This embodiment provides a frame structure and a vehicle. The vehicle includes the aforementioned frame structure, which is foldable, allowing the vehicle to switch between a folded and an unfolded state. When unfolded, the vehicle can be used for riding, and when folded, it can be relatively closed to reduce the overall footprint, improving the vehicle's usability and portability. It should be noted that the vehicle can be a child trailer, a campervan, or a folding bed, etc., and is not specifically limited here.

[0057] like Figures 1 to 6 As shown, the frame structure has an unfolded state and a folded state. The frame structure includes a frame assembly 1, which includes a first frame 11, a second frame 12, a first connecting unit 13, and a second connecting unit 14. The first frame 11 and the second frame 12 are arranged opposite to each other along a first direction. The two ends of the first connecting unit 13 are respectively hinged to one end of the first frame 11 and the second frame 12, and the two ends of the second connecting unit 14 are respectively hinged to the other end of the first frame 11 and the second frame 12.

[0058] When the frame structure is in the unfolded state, the first frame 11, the first connecting unit 13, the second frame 12, and the second connecting unit 14 are sequentially arranged circumferentially to form an accommodating space. At least one pair of hinge axes, diagonally distributed along the first and second directions, can approach each other to switch the frame structure from the unfolded state to the folded state. The first and second directions are perpendicular to each other. This arrangement significantly reduces the volume of the folded load, facilitating storage and transportation, and the frame structure also boasts a simple structure.

[0059] In this embodiment, the first connecting unit 13 includes N sequentially movably connected structural components 130, and the second connecting unit 14 includes N sequentially movably connected structural components 140, where N≥2; when the frame structure is in a folded state, structural components 130 and structural components 140 are alternately arranged along the first direction.

[0060] Specifically, the first frame 11 and the adjacent structural member 130 are hinged by the first hinge axis 151, the second frame 12 and the adjacent structural member 130 are hinged by the second hinge axis 152; the first frame 11 and the adjacent structural member 140 are hinged by the third hinge axis 153, and the second frame 12 and the adjacent structural member 140 are hinged by the fourth hinge axis 154; during the process of switching the frame structure to the folded state, the first connecting unit 13 moves closer along the first direction and is folded between the first frame 11 and the second frame 12.

[0061] N can be either odd or even. This embodiment uses an even N as an example to describe the frame structure in detail.

[0062] During the process of switching the frame structure to the folded state, the first connecting unit 13 and the second connecting unit 14 both move closer together along the first direction and are folded between the first frame 11 and the second frame 12.

[0063] For example, N=2, the two structural components 130 of the first connecting unit 13 are respectively referred to as the first structural component 131 and the second structural component 132, and the two structural components 140 of the second connecting unit 14 are respectively referred to as the third structural component 141 and the fourth structural component 142.

[0064] like Figure 1 and Figure 2 As shown, the first frame 11 and the first structural member 131 are hinged by the first hinge axis 151; the second frame 12 and the second structural member 132 are hinged by the second hinge axis 152; the first frame 11 and the third structural member 141 are hinged by the third hinge axis 153; and the second frame 12 and the fourth structural member 142 are hinged by the fourth hinge axis 154. The first structural member 131 and the second structural member 132 are hinged by the fifth hinge axis 155, and the third structural member 141 and the fourth structural member 142 are hinged by the sixth hinge axis 156. When the frame structure is in the unfolded state, the first hinge axis 151, the second hinge axis 152, the third hinge axis 153, the fourth hinge axis 154, the fifth hinge axis 155, and the sixth hinge axis 156 all extend in the vertical direction.

[0065] When the enclosure structure is in the unfolded state, it is roughly a rectangular frame. The first hinge axis 151, the fifth hinge axis 155, the sixth hinge axis 156, and the third hinge axis 153 are distributed in a roughly rectangular pattern along the circumference. The fifth hinge axis 155 and the third hinge axis 153 are diagonally distributed along the first and second directions, and the sixth hinge axis 156 and the first hinge axis 151 are diagonally distributed along the first and second directions. Similarly, the second hinge axis 152, the fourth hinge axis 154, the sixth hinge axis 156, and the fifth hinge axis 155 are distributed in a roughly rectangular pattern along the circumference. The second hinge axis 152 and the sixth hinge axis are diagonally distributed along the first and second directions, and the fifth hinge axis 155 and the fourth hinge axis 154 are diagonally distributed along the first and second directions.

[0066] When switching the frame structure from an unfolded state to a folded state, taking the first frame 11 as an example with the frame fixed, press the connection points of the first structural member 131 and the second structural member 132, as well as the connection points of the third structural member 141 and the fourth structural member 142, in the second direction. The first structural member 131 rotates around the first hinge axis 151 towards the first frame 11; at the same time, the first structural member 131 will drive the second structural member 132 to rotate around the fifth hinge axis 155, causing the second structural member 132 to move closer to the first structural member 131 in the first direction. During this process, the fifth hinge axis 155 moves along the first and second directions. All gradually approach the third hinge axis 153; the third structural member 141 rotates around the third hinge axis 153 toward the first frame 11, and at the same time the third structural member 141 will drive the fourth structural member 142 to rotate around the sixth hinge axis 156, so that the fourth structural member 142 approaches the third structural member 141 along the first direction. During this process, the sixth hinge axis 156 gradually approaches the second hinge axis 152 along both the first and second directions, so that the second frame 12 approaches the first frame 11 along the first direction, and the first connecting unit 13 and the second connecting unit 14 are gathered between the first frame 11 and the second frame 12 along the first direction.

[0067] like Figure 1 and Figure 2 As shown, in this embodiment, the first frame 11 includes a frame body 111 extending along a second direction, and two frame connecting portions 112 disposed on the side of the frame body 111 near the second frame 12; one end of one frame connecting portion 112 is hinged to the first connecting unit 13 via a first hinge shaft 151; one end of the other frame connecting portion 112 is hinged to the second connecting unit 14 via a third hinge shaft 153. Specifically, one frame connecting portion 112 is hinged to the first structural member 131 via the first hinge shaft 151, and the other frame connecting portion 112 is hinged to the third structural member 141 via the third hinge shaft 153.

[0068] The second frame 12 includes a frame body 121 extending along a second direction, and two frame connecting portions 122 disposed on the side of the frame body 121 near the first frame 11; one end of one frame connecting portion 122 is hinged to the first connecting unit 13 via a second hinge shaft 152, and one end of the other frame connecting portion 122 is hinged to the second connecting unit 14 via a fourth hinge shaft 154. Specifically, one end of one frame connecting portion 122 is hinged to the second structural member 132 via the second hinge shaft 152, and the other frame connecting portion 122 is hinged to the fourth structural member 142 via the fourth hinge shaft 154.

[0069] For example, the first frame 11 and the second frame 12 adopt a U-shaped rod structure, and the first structural member 131, the second structural member 132, the third structural member 141, and the fourth structural member 142 all adopt rod structures. In other embodiments, the first frame 11 and the second frame 12 may also adopt a U-shaped plate structure.

[0070] like Figure 6 As shown, when the frame structure is in a folded state, along the first direction, the first hinge axis 151 and the fifth hinge axis 155 are closer to the frame body 111 than the third hinge axis 153, and the fourth hinge axis 154 and the sixth hinge axis 156 are closer to the frame body 21 than the second hinge axis 152.

[0071] Specifically, such as Figure 6 As shown, the minimum distance between the first hinge axis 151 and the central axis of the frame body 111, and the minimum distance between the fourth hinge axis 154 and the central axis of the frame body 2 121 are both L1; the minimum distance between the second hinge axis 152 and the central axis of the frame body 111, and the minimum distance between the third hinge axis 153 and the central axis of the frame body 2 121 are both L2, where L1 < L2.

[0072] This configuration allows the first structural member 131 to be folded between the first preset plane 303 where the frame body 111 and the third hinge axis 153 are located, and the fourth structural member 142 to be folded between the second frame body 121 and the second preset plane 304 where the second hinge axis 152 is located, thereby reducing the space occupied by the entire frame structure along the first direction after folding. It should be noted that both the first preset plane 303 and the second preset plane 304 are perpendicular to the first direction, the third hinge axis 153 is located on the first preset plane 303, and the second hinge axis 152 is located on the second preset plane 304.

[0073] In this embodiment, for a frame structure with N=2, when the frame structure is in a folded state, along the first direction, the second hinge axis 152 is closer to the frame body 111 than the third hinge axis 153, thereby reducing the space occupied by the entire frame structure along the first direction after folding.

[0074] In this embodiment, for a frame structure with N=2, when the frame structure is in a folded state, the first connecting unit 13 is folded between the frame body 111 and the second connecting unit 14, and the second connecting unit 14 is folded between the frame body 121 and the first connecting unit 13.

[0075] like Figure 6As shown, in this embodiment, when the frame structure is in a folded state, the first hinge shaft 151, the second hinge shaft 152, the sixth hinge shaft 156, the fifth hinge shaft 155, the third hinge shaft 153, and the fourth hinge shaft 154 are sequentially distributed along the second direction; the first hinge shaft 151, the second hinge shaft 152, and the sixth hinge shaft 156 are located at one end of the frame structure in the second direction and are sequentially distributed along the first direction; the fourth hinge shaft 154, the third hinge shaft 153, and the fifth hinge shaft 155 are located at the other end of the frame structure in the second direction and are sequentially distributed along the first direction.

[0076] like Figure 2 As shown, when the frame structure is in the unfolded state, two structural members 130, hinged by the fifth hinge axis 155, abut against each other along the first direction, with the abutment position located on the side of the first plane 301 facing the second connecting unit 14. The first plane 301 is perpendicular to the second direction, and the central axis of the fifth hinge axis 155 is located on the first plane 301. For example, structural member 130 is a rod-shaped structure, and when the frame structure is in the unfolded state, the central axes of each structural member 130 of the first connecting member 23 unit are located on the same straight line.

[0077] It should be noted that, in other embodiments, structural member 130 and the corresponding first connector 23 can be integrated into a single plate structure.

[0078] During the process of switching the frame structure from the folded state to the unfolded state, this setting prevents two adjacent structural members 130 from continuing to rotate when the frame structure is switched to the unfolded state, thus reminding the user that the frame structure has been switched to the unfolded state.

[0079] Specifically, taking N=2 as an example, such as Figures 1 to 6As shown, one end of the first structural member 131 is provided with a first connecting portion, and one end of the second structural member 132 is provided with a second connecting portion. The first connecting portion and the second connecting portion are arranged vertically. One end of the fifth hinge shaft 155 is connected to one of the first connecting portion and the second connecting portion, and the other end of the fifth hinge shaft 155 is rotatably inserted through the other of the first connecting portion and the second connecting portion. When the frame structure is in the unfolded state, the first connecting portion is located on the side of the first structural member 131 facing away from the second connecting unit 14 along the second direction, and the second connecting portion is located on the side of the second structural member 132 facing away from the second connecting unit 14 along the second direction. The end of the first structural member 131 with the first connecting portion and the end of the second structural member 132 with the second connecting portion abut against each other along the first direction. When the frame structure is in the unfolded state, the first hinge shaft 151 and the second hinge shaft 152 are located on the side of the first plane 301 facing the second connecting unit 14. In other words, the first hinge shaft 151 and the second hinge shaft 152 are both located between the first plane 301 and the second plane 302. The second plane 302 is perpendicular to the second direction and the central axis of the sixth hinge shaft 156 is located in the second plane 302.

[0080] like Figure 1 and Figure 2 As shown, when the frame structure is in the unfolded state, the two structural members 140, hinged by the sixth hinge shaft 156, abut against each other along the second direction, and the abutment position is located on the side of the second plane 302 facing the first connecting unit 13. For example, the structural member 140 is a rod-shaped structure, and when the frame structure is in the unfolded state, the central axes of each structural member 140 of the second connecting unit 14 are located on the same straight line.

[0081] During the process of switching the frame structure from the folded state to the unfolded state, this setting prevents the two adjacent structural members 140 from continuing to rotate when the frame structure is switched to the unfolded state, thus reminding the user that the frame structure has been switched to the unfolded state.

[0082] Specifically, taking N=2 as an example, such as Figures 1 to 6 As shown, one end of the third structural member 141 is provided with a third connecting portion, and one end of the fourth structural member 142 is provided with a fourth connecting portion. The third and fourth connecting portions are arranged vertically. One end of the sixth hinge shaft 156 is connected to one of the third and fourth connecting portions, and the other end of the sixth hinge shaft 156 is rotatably inserted through the other of the third and fourth connecting portions. Figure 1 and Figure 2As shown, when the frame structure is in the unfolded state, the third connecting part is located on the side of the third structural member 141 facing away from the first connecting unit 13 along the second direction, and the fourth connecting part is located on the side of the fourth structural member 142 facing away from the first connecting unit 13 along the second direction. The end of the third structural member 141 where the third connecting part is located and the end of the fourth structural member 142 where the fourth connecting part is located abut against each other along the first direction.

[0083] When the frame structure is in the unfolded state, the third hinge axis 153 and the fourth hinge axis 154 are located on the side of the second plane 302 facing the first connecting unit 13. In other words, the third hinge axis 153 and the fourth hinge axis 154 are both located between the first plane 301 and the second plane 302.

[0084] In this embodiment, the frame structure also includes a folding locking component disposed on the frame assembly 1. The folding locking component can lock the frame structure to keep it in a folded state; the folding locking component can also unlock the frame structure, allowing it to switch from a folded state to an unfolded state. After the frame structure is folded, keeping it in a folded state through the folding locking component facilitates the transportation and storage of the frame structure.

[0085] Taking a frame structure with N=2 as an example, when the frame structure is in a folded state, the first structural member 131, the second structural member 132, the fourth structural member 142, and the third structural member 141 are sequentially distributed along a first direction. The folding locking assembly includes a first locking unit and a second locking unit, wherein the first locking unit can selectively lock or unlock the first structural member 131 and the second structural member 132; and the second locking unit can selectively lock or unlock the third structural member 141 and the fourth structural member 142.

[0086] The first and second locking units can adopt magnetic attraction structures, snap-fit ​​structures, or binding ropes, etc. These are all commonly used locking structures in this field, and will not be described in detail here.

[0087] This embodiment also provides a carrier, including the aforementioned frame structure. The carrier can be a folding bed or a stroller, etc. The frame structure can serve as the bed frame of a folding bed or the frame of a stroller such as a children's vehicle or a campervan. Taking the frame structure as a stroller frame as an example, two frame components 1 are provided, which are spaced apart along a third direction and connected by multiple connectors arranged circumferentially. The third direction is perpendicular to the first direction and the second direction. Specifically, the third direction is the vertical direction, the first direction is the front-back direction, and the second direction is the left-right direction.

[0088] Specifically, such as Figure 1 and Figure 2As shown, when the enclosure structure is in the unfolded state, the two enclosure components 1 are distributed vertically, and the two structural members 130 arranged vertically opposite each other are connected by at least one connector, and the two structural members 140 arranged vertically opposite each other are connected by at least one connector; the two first enclosures 11 are connected by at least one connector, and the two second enclosures 12 are connected by at least one connector.

[0089] For example, the connectors are rod-shaped structures, and multiple connectors include frame connector 1 21, frame connector 22, first connector 23, and second connector 24. Two first frames 11 are connected by two frame connectors 1 21 spaced apart along a second direction, and two second frames 12 are connected by two frame connectors 22 spaced apart along a second direction. When the frame structure is in the unfolded state, two structural members 130 arranged vertically opposite each other are connected by two first connectors 23, and two structural members 140 arranged vertically opposite each other are connected by two second connectors 24.

[0090] When the enclosure structure is in the unfolded state, the two enclosure components 1 form an accommodating space through multiple connectors arranged circumferentially.

[0091] like Figure 1 and Figure 6 As shown, for ease of description, the upper frame component 1 is referred to as the upper frame component, and the lower frame component 1 is referred to as the lower frame component.

[0092] In this embodiment, the bottom of the lower frame assembly is movably connected to casters to facilitate vehicle movement. Exemplarily, four casters are provided, arranged in pairs. One pair of casters is movably connected to the left and right ends of the first frame 11 of the lower frame assembly, and the other pair is movably connected to the left and right ends of the second frame 12 of the lower frame assembly. These casters can be omnidirectional wheels. The structure of the omnidirectional wheels and how they are installed in the lower frame assembly are existing technologies in the art and will not be described in detail here.

[0093] In this embodiment, as Figure 1 , Figure 3 , Figures 7 to 9 As shown, the vehicle also includes a load-bearing component 3, which is movably connected to the frame component 1. The load-bearing component 3 has an unfolded position and a folded position. When the frame structure is in the unfolded state, the load-bearing component 3 can switch between the unfolded and folded positions. When the load-bearing component 3 is in the folded position, the frame structure can switch between the unfolded and folded states. The load-bearing component 3 can be used for users to sit, lie down, or place items, etc.

[0094] Before switching the frame structure from the unfolded state to the folded state, first switch the load-bearing component 3 from the unfolded position to the folded position, and then fold the frame structure. Conversely, first switch the frame structure from the folded state to the unfolded state, and then switch the load-bearing component 3 from the folded position to the unfolded position. This arrangement avoids the load-bearing component 3 affecting the folding of the frame structure.

[0095] It should be noted that, in other embodiments, the supporting component 3 can be detachably connected to the frame component 1. When the supporting component 3 is separated from the frame component 1, the frame structure can switch between an unfolded state and a folded state.

[0096] In this embodiment, the carrier further includes a first support limiting unit, which is connected to the first connecting unit 13 and / or the second connecting unit 14. When the carrier component 3 is in the unfolded position, the carrier component 3 is supported by the first support limiting unit, and the carrier component 3 is clamped between the first connecting unit 13 and the second connecting unit 14 along the second direction.

[0097] When switching the frame structure from the unfolded state to the folded state, it is necessary to press the connection positions of the first structural member 131 and the second structural member 132, as well as the connection positions of the third structural member 141 and the fourth structural member 142, in the second direction so that the fifth hinge shaft 155 and the sixth hinge shaft 156 move closer to each other in the second direction. The load-bearing component 3 in the unfolded state will restrict this action, thereby keeping the frame structure in the unfolded state and improving the stability of the frame structure in the unfolded state.

[0098] For example, the support component 3 includes a first support body 31 and a second support body 32, wherein the first support body 31 is rotatably connected to the first frame 11 of the lower frame component via a first support hinge shaft 341, and the second support body 32 is rotatably connected to the second frame 12 of the lower frame component via a second support hinge shaft 342, and both the first support hinge shaft 341 and the second support hinge shaft 342 extend along a second direction.

[0099] When the frame structure is in the unfolded state, the first support 31 and the second support 32 are distributed along the first direction. Rotating the first support 31 to bring it closer to the first frame 11 and rotating the second support 32 to bring it closer to the second frame 12 can switch the support assembly 3 to the folded position.

[0100] It should be noted that the first support 31 and the second support 32 can be flat plate structures or frame structures, etc. For example, both the first support 31 and the second support 32 are flat plate structures.

[0101] In this embodiment, when the frame structure is in the unfolded state, in the lower frame assembly, both structural member 130 and structural member 140 arranged facing each other along the second direction are provided with first support and limiting units. For example, each structural member 130 and each structural member 140 is provided with one first support and limiting unit. This arrangement can improve the stability of the seat plate.

[0102] It should be noted that the number of first support limiting units provided on each structural component 130 and each structural component 140 is not limited to one; it can also be two, three, or more. The first support limiting unit can be a protrusion or the like that fixedly connected to the structural component it is located on.

[0103] In this embodiment, the first hinge axis 151 is located between the first load-bearing hinge axis 341 and the third hinge axis 153 along the first direction, which can prevent the first load-bearing body 31 and the first load-bearing hinge axis 341 from interfering with the folding of the frame structure. The fourth hinge axis 154 is located between the second load-bearing hinge axis 342 and the second hinge axis 153 along the first direction. This can prevent the second load-bearing body 32 and the second load-bearing hinge axis 342 from interfering with the folding of the frame structure.

[0104] It should be noted that, in other embodiments, the first support 31 and the second support 32 can be hinged together by a hinge axis extending along the second direction, and the connection between the first support 31 and the first frame 11 or the connection between the second support 32 and the second frame 12 can be cancelled. Taking the cancellation of the connection between the first support 31 and the first frame 11 as an example, before switching the frame structure from the unfolded state to the folded state, the first support 31 and the second support 32 are folded in half, and the second support 32 is rotated toward the second frame 12.

[0105] In this embodiment, as Figure 1 , Figure 3 , Figures 7 to 9 As shown, the support component 3 also includes a foot pocket unit 33 movably connected to the lower frame component. The support component 3 has a sitting position and a lying position. When the support component 3 is in the sitting position, the support component 3 is in the unfolded position, the foot pocket unit 33 forms a footrest space 35 with a top opening, and the surface of the support component 3 forms a support surface for sitting. When the support component 3 is in the lying position, the support component 3 is in the unfolded position, and the surface of the foot pocket unit 33 and the upper surface of the support component 3 together form a support surface for lying down.

[0106] Specifically, there are two foot pocket units 33. The support component 3 is in the unfolded position. The two foot pocket units 33 are arranged between the first support body 31 and the second support body 32 along the first direction. Each foot pocket unit 33 includes a foot pedal connection part 332 and a foot pedal part 331 rotatably connected thereto. One end of the foot pedal connection part 332 of one foot pocket unit 33 is rotatably connected to the end of the first support body 31 away from the first frame 11, and one end of the foot pedal connection part 332 of the other foot pocket unit 33 is rotatably connected to the end of the second support body 32 away from the second frame 12.

[0107] When the user needs to lie down, the support component 3 is switched from a sitting to a lying position. The surface of the footrest unit 33 and the upper surface of the support component 3 together form a support surface, allowing the user to lie down. When the user needs to sit in the stroller, the support component 3 is switched from a lying to a sitting position, so that the footrest unit 33 forms a footrest space 35 with an open top. The upper surface of the support component 3 forms a support surface for sitting, allowing the user to sit on the upper surface of the support component 3 and extend their feet into the footrest space 35. This stroller can meet both lying and sitting needs, providing a high level of user experience.

[0108] When the support component 3 is in a seated position, the foot pedal 331 is located below the support component 3. The foot pedal 331, the foot pedal connecting part 332 and the first support body 31 form a Z-shaped structure, and the foot pedal 331, the foot pedal connecting part 332 and the second support body 32 form a Z-shaped structure.

[0109] For example, the foot pedal 331 and the foot pedal connecting part 332 are connected by a hinge, and the foot pedal connecting part 332 is connected to the corresponding load-bearing component 3 by a hinge, which makes the connection convenient, quick and easy and low cost.

[0110] In this embodiment, as Figure 1 and Figure 8 As shown, the lower frame assembly is movably connected to a second support limiting unit 4. The second support limiting unit 4 has a first position and a second position. When the second support limiting unit 4 is in the first position, it blocks one side of the foot pocket unit 33 to restrict the movement of the foot pocket unit 33, so that the supporting assembly 3 is kept in at least one of the lying and sitting positions. When the second support limiting unit 4 is in the second position, the foot pocket unit 33 can move so that the supporting assembly 3 can switch between the lying and sitting positions.

[0111] For example, each first structural member 131 and each second structural member 132 is rotatably connected to a second support limiting unit 4. When the bearing assembly 3 is in a lying position, the foot pedal 331 is located above the foot pedal connecting part 332, and the foot pedal 331 is supported by the foot pedal connecting part 332. After switching the bearing assembly 3 to a lying position, rotating the second support limiting unit 4 allows the free end of the second support limiting unit 4 to rotate below the corresponding bearing body, whereby the second support limiting unit 4 supports the foot pedal connecting part 332. Before switching the bearing assembly 3 to a sitting position, rotating the second support limiting unit 4 so that the second support limiting unit 4 is on one side of the foot pedal connecting part 332 in the second direction, then rotating the foot pedal connecting part 332 downwards, and then flipping the foot pedal 331, the bearing assembly 3 can be switched to a sitting position.

[0112] It should be noted that when the vehicle is a folding bed, the aforementioned tow bar 101, push handle 200, and foot pocket assembly are removed.

[0113] In this embodiment, as Figure 1 As shown, a fixing part 102 is provided on the first frame 11 of the upper frame assembly. The carrier also includes a tow bar 101. The lower end of the tow bar 101 is movably connected to the first frame 11 of the lower frame assembly, and the upper end of the tow bar 101 is detachably connected to the fixing part 102.

[0114] For example, the lower end of the tow rod 101 is hinged to the middle of the first frame 11 of the lower frame assembly via a hinge shaft extending in the second direction. The fixing part 102 is disposed in the middle of the first frame 11 of the upper frame assembly. The fixing part 102 has a C-shaped structure. Pressing the tow rod 101 will insert the tow rod 101 into the C-shaped structure to lock the tow rod 101 into the fixing part 102. Under the action of external force, the tow rod 101 can be dislodged from the C-shaped structure.

[0115] Release the latch between the tow bar 101 and the fixing part 102. The upper end of the tow bar 101 will come out of the fixing part 102. Rotate the tow bar 101 and pull the tow bar 101 to drag the entire vehicle.

[0116] In this embodiment, the tow rod 101 is a telescopic rod, which facilitates adjustment of the length of the tow rod 101 according to actual needs. Moreover, before or after switching the frame structure to the folded state, the retracted tow rod 101 engages with the fixing part 102. As for the specific structure of the push rod, it is prior art in the field and will not be described in detail here.

[0117] In this embodiment, as Figure 1 As shown, the vehicle also includes a push handle 200, one end of which is movably connected to the second frame 12 of the upper frame assembly. Specifically, one end of the push handle 200 is rotatably connected to the second frame 12 of the upper frame assembly, allowing the vehicle to be propelled by the push handle 200.

[0118] Rotating the push handle 200 allows it to be folded between the two second frames 12. When the frame structure is in a folded state, the push handle 200 is folded between the two second frames 12, thus preventing the push handle 200 from occupying the space along the first direction of the folded frame structure.

[0119] For example, the push handle 200 is a U-shaped rod, and the two ends of the U-shaped rod are respectively hinged to the left and right ends of the second frame 12 of the upper frame assembly through a hinge shaft extending in the second direction.

[0120] Example 2

[0121] The difference between this embodiment and Embodiment 1 is that, as Figure 10 and Figure 11 As shown, the first connecting unit 13 is a straight rod, and the second connecting unit 14 is also a straight rod, meaning the frame structure is a four-bar linkage structure. When the frame structure is in a folded state, the overall frame structure is V-shaped. For example, the second frame 12 and the second connecting unit 14 are folded between the first frame 11 and the first connecting unit 13.

[0122] Example 3

[0123] The difference between this embodiment and Embodiment 1 is that, as Figure 12 As shown, N≥3. When the enclosure structure is equipped with an enclosure component 1, it can also be used as a ground fence or a bed fence, etc. The number of N can be determined according to the size when it is used as a ground fence or a bed fence, and will not be specifically limited here.

[0124] Among the three adjacent structural members 130 distributed along the first direction, the middle structural member 130 and one of the structural members 130 are hinged together by a fifth hinge axis 155. A transition member 133 is arranged between the middle structural member 130 and another structural member 130. The transition member 133 is hinged to the two structural members 130 at each end of the first direction by a seventh hinge axis 157. Among the three adjacent structural members 2 140 distributed along the first direction, the middle structural member 2 140 and one of the structural members 2 140 are hinged together by an eighth hinge axis 158. A transition member 2 143 is arranged between the middle structural member 2 140 and another structural member 2 140. The transition member 2 143 is hinged to the two transition members 2 143 at each end of the first direction by an eighth hinge axis 158 156.

[0125] For ease of description, the first structural member 131 and the second structural member 132 hinged to it via the fifth hinge axis 155 in Embodiment 1 are referred to as a first structural unit, and the third structural member 141 and the fourth structural member 142 hinged to it via the eighth hinge axis 158 in Embodiment 1 are referred to as a second structural unit. For a frame structure where N is an even number greater than 3, the frame structure includes at least two first structural units and at least two second structural units, and the number of first structural units and second structural units is equal.

[0126] like Figure 12 As shown, taking an even-numbered frame structure where N is greater than 3 as an example, two adjacent first structural units are connected by a transition member 133, and two adjacent second structural units are connected by a transition member 143. When the frame structure is in a folded state, along the first direction from the first frame 11 to the second frame 12, the frame connecting part 112, at least one transition member 133, and the frame connecting part 122 located at the same end of the frame structure in the second direction gradually move closer to the second connecting unit 14 along the direction from the first connecting unit 13 to the second connecting unit 14, and the frame connecting part 112, at least one transition member 143, and the frame connecting part 112 located at the same end of the frame structure in the second direction gradually move away from the first connecting unit 13 along the direction from the first connecting unit 13 to the second connecting unit 14. The first structural units and the second structural units are arranged alternately along the first direction. In other words, along the first direction, two adjacent first structural units have one second structural unit, and two adjacent second structural units have one first structural unit.

[0127] When the frame structure is in a folded state, the transition piece 133 and the two structural pieces 130 connected to it form a first U-shaped space with a gradually expanding opening, and the second structural unit between the two first structural units is folded into the first U-shaped space; the transition piece 143 and the two structural pieces 140 connected to it form a second U-shaped space with a gradually expanding opening, and the first structural unit between the two second structural units is folded into the second U-shaped space.

[0128] Example 4

[0129] The difference between this embodiment and Embodiment 1 is that, as Figure 13As shown, N is an odd number greater than 2. During the process of switching the frame structure to the folded state, each structural component 130 of the first connecting unit 13 moves closer together along the first direction and is folded between the first frame 11 and the second frame 12. Each structural component 140 of the second connecting unit 14 moves closer together along the first direction, and all structural components 140 except those adjacent to the second frame 12 are folded between the structural component 140 adjacent to the second frame 12 and the first frame 11. Taking N=3 as an example, when the frame structure is in the folded state, the frame structure as a whole is M-shaped.

[0130] Example 5

[0131] The difference between this embodiment and Embodiment 1 is that: there is one frame component 1. When the frame structure is in the unfolded state, the frame structure also includes a barrier component. The barrier component is movably connected to at least one of the first frame 11, the second frame 12, the first connecting unit 13, and the second connecting unit 14. When the frame structure is in the unfolded state, the barrier component is located above the frame component 1. The barrier component can cover or open at least a portion of the circumferential area of ​​the frame component 1. The first direction and the second direction are both perpendicular to the vertical direction.

[0132] In this embodiment, the enclosure assembly 1 includes two first enclosures 11 and two second enclosures 12. The two first enclosures 11 are connected by at least two connectors spaced apart along a second direction, and the two second enclosures 12 are connected by at least two connectors spaced apart along a second direction.

[0133] For example, the two first frames 11 are connected at both ends in the second direction by a connector, and the two second frames 12 are connected at both ends in the second direction by a connector.

[0134] In this embodiment, when the frame structure is in the unfolded state, two enclosure components are arranged on one side of the frame structure in the second direction. The two enclosure components are distributed along the first direction. One enclosure component is hinged to the first frame 11 via an enclosure hinge axis, and the other enclosure component is hinged to the second frame 12 via an enclosure hinge axis. The enclosure hinge axis is vertically arranged, so that the two enclosure components form a double-door structure. A first connecting unit 13 or a second connecting unit 14 is arranged on the other side of the frame structure in the second direction. In other words, in this embodiment, one of the first connecting unit 13 and the second connecting unit 14 of the upper frame component in Embodiment 1 is replaced with the double-door structure formed by the two enclosure components mentioned above. For example, in this embodiment, the first connecting unit 13 of the upper enclosure component in Embodiment 1 is replaced with the enclosure component mentioned above.

[0135] Users can rotate the fencing component to cover or open at least a portion of the circumference of the fencing component 1.

[0136] It should be noted that the first connecting unit 13 and the second connecting unit 14 in Embodiment 1 can each be replaced with one of the above-mentioned double door structures. One of the structural components 130 or one of the structural components 140 in Embodiment 1 can also be replaced with the above-mentioned enclosure assembly. Alternatively, one of the first connecting unit 13 and the second connecting unit 14 can be removed, and the other of the first connecting unit 13 and the second connecting unit 14 can be replaced with the above-mentioned double door structure.

[0137] When switching the frame structure of this embodiment from an unfolded state to a folded state, taking the first frame 11 as an example with the first frame 11 fixed, first rotate the two enclosure components, so that one enclosure component gradually approaches the first frame 11 and the other frame component 1 gradually approaches the second frame 12. Then, press the connection positions of the first structural member 131 and the second structural member 132, as well as the connection positions of the third structural member 141 and the fourth structural member 142, towards each other along the second direction. The first structural member 131 rotates around the first hinge axis 151 towards the first frame 11; at the same time, the first structural member 131 will drive the second structural member 132 to rotate around the fifth hinge axis 155, so that the second structural member 132 approaches the first structural member along the first direction. 131. During this process, the fifth hinge axis 155 gradually approaches the third hinge axis 153 along both the first and second directions; the third structural member 141 rotates around the third hinge axis 153 toward the first frame 11, and at the same time, the third structural member 141 will drive the fourth structural member 142 to rotate around the sixth hinge axis 156, so that the fourth structural member 142 approaches the third structural member 141 along the first direction. During this process, the sixth hinge axis 156 gradually approaches the second hinge axis 152 along both the first and second directions, so that the second frame 12 approaches the first frame 11 along the first direction, and the first connecting unit 13 and the second connecting unit 14 are gathered together between the first frame 11 and the second frame 12 along the first direction.

[0138] To facilitate understanding, let's take the unfolded frame structure as an example to introduce the structure of the fencing assembly. The fencing assembly can be a flat plate, with one end of the plate rotatably connected to the first frame 11 and the other end of the plate rotatably connected to the second frame 12. The fencing assembly can also be a frame structure formed by multiple crisscrossing rods.

[0139] In this embodiment, the enclosure structure also includes an enclosure locking component, which is movably connected to the two enclosure components. The enclosure locking component can connect the two enclosure components to keep the enclosure component 1 in the unfolded state. The enclosure locking component can also unlock the two enclosure components to allow the enclosure components to be rotated, which facilitates the subsequent switching of the enclosure structure to the folded state.

[0140] It should be noted that the fence locking assembly can employ a magnetic structure, such as installing a permanent magnet on one fence assembly and a ferromagnetic structural component or permanent magnet on the other. When the fence structure is in the unfolded state, the two fence assemblies can be magnetically attracted and fixed. When it is necessary to switch the fence structure to the folded state, only a large external force is needed to rotate the fence assembly. The fence locking assembly can also employ a snap-fit ​​structure as in existing technology to snap the two fence assemblies together, or it can employ positioning pins passing through the two fence assembly 1, etc., which will not be listed here.

[0141] It is worth noting that the directional terms such as "front," "rear," "left," "right," "up," and "down" mentioned above are all based on the direction relative to the vehicle's direction of travel when the vehicle is in use. That is, the front side of a structure refers to the side of the structure facing the direction of travel of the vehicle, and the rear side of a structure refers to the side of the structure away from the direction of travel of the vehicle.

[0142] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
