[0049] like Figure 1 and Figure 2 As shown, this embodiment provides a vehicle comprising a frame 1, a seat 2, a linkage mechanism 8, and a drive mechanism 3. The frame 1 has a first support 111 and a second support 112 rotatably connected. The seat 2 has a frame body 21 rotatably mounted on the first support 111 and a seat plate 23 mounted on the frame body 21. The linkage mechanism 8 is movably connected to the second support 112 and the frame body 21, respectively, so that when the frame body 21 folds towards the first support 111, the second support 112 folds towards the first support 111. The drive mechanism 3 is mounted on the frame 1 and drives the frame body 21 to fold towards the first support 111 or drives the second support 112 to fold towards the first support 111. The seat 2 has an unfolded state and a folded state. The drive mechanism 3 can drive the frame body 21 to unfold or fold, replacing manual folding or unfolding of the vehicle, simplifying operation and making it convenient for users. When the vehicle is folded, the seat frame 2 and the second support 112 are automatically folded at the same time, realizing the simultaneous automatic folding of components at different positions on the vehicle, which saves time and effort and makes the folding operation relatively simple.

[0050] The second support 112 unfolds or folds relative to the first support 111 in the second direction, and the frame 21 unfolds or folds relative to the first support 111 in the first direction. When the vehicle is folded, the dimensions of the vehicle decrease in both the first and second directions.

[0051] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the frame 1 has a pair of side frames 11 arranged opposite each other and a transverse support beam 12 connected between the pair of side frames 11. Each side frame 11 includes a first bracket 111 and a second bracket 112, that is, there are two first brackets 111, which are arranged opposite each other, and each first bracket 111 is rotatably connected to a second bracket 112. The drive mechanism 3 is disposed on the transverse support beam 12, and the transverse support beam 12 is rotatably connected to the side frames 11 respectively. Specifically, the transverse support beam 12 is rotatably connected to the two first brackets 111. The frame body 21 is rotatably connected to the side frames 11, specifically, the frame body 21 is rotatably connected to the first brackets 111. Further, one end of the two side frames 11 is rotatably connected to both ends of the transverse support beam 12 respectively. Specifically, the transverse support beam 12 is rotatably connected between the two first brackets 111, and the other end of the two side frames 11 is connected to a crossbeam. The crossbeam and the two side frames 11 are integrally formed and form a U-shaped structure. Optionally, the transverse support beam 12 is positioned relative to the rear side of the frame 1.

[0052] The vehicle also includes a first wheel set 4 and a second wheel set 5, which are spaced apart on the side frame 11 along a second direction. Specifically, the first wheel set 4 and the second wheel set 5 are spaced apart on the first bracket 111 along a second direction. The first wheel set 4 is connected to the side frame 11, specifically, the first wheel set 4 is connected to the second bracket 112. When the drive mechanism 3 drives the seat frame 2 to fold towards the frame 1, the seat frame 2 drives the first wheel set 4 to fold towards the second wheel set 5 along the second direction. When the drive mechanism 3 drives the seat frame 2 to unfold, the seat frame 2 drives the first wheel set 4 to unfold away from the second wheel set 5 along the second direction.

[0053] The second wheel set 5 is located at the front along the second direction, and the first wheel set 4 is located at the rear. The second wheel set 5 includes two second wheels, which are respectively connected to the front ends of the two side frames 11. The second wheels can be swivel wheels to facilitate vehicle turning.

[0054] The second bracket 112 is rotatably connected to the first bracket 111, and the first wheel set 4 is fixedly connected to the second bracket 112. In the folded state, the seat frame 2 drives the second bracket 112 to fold towards the first bracket 111 through the linkage mechanism 8, which in turn drives the first wheel set 4 to fold towards the second wheel set 5, thereby reducing the folded size of the vehicle in the second direction.

[0055] The linkage mechanism 8 includes connecting rods 81 pivotally connected to the frame 21 and the second support 112 respectively. The frame 21 is rotatably mounted on the first support 111 along the first rotation axis m1, and a portion of the frame 21 extends to the other side of the first rotation axis m1 to form an extension, to which the connecting rods 81 are pivotally connected. When the drive mechanism 3 drives the frame 21 to rotate and fold toward the first support 111, the frame 21, through the connecting rods 81, drives the second support 112 to move closer to the first support 111 and fold.

[0056] The first wheel assembly 4 includes two first wheels, with a wheel axle connecting the two first wheels. The wheel axle is fixedly connected to the second bracket 112, and each link 81 is rotatably connected to the corresponding second bracket 112.

[0057] In some embodiments, the drive mechanism 3 drives the frame 21 to fold towards the first support 111. Optionally, the drive mechanism 3 includes a transmission rod 31 and a drive member 32 that drives the transmission rod 31 to move. The drive member 32 is rotatably mounted on the frame 1 and can drive the transmission rod 31 to rotate towards the frame 1, so that the transmission rod 31 can be rotated and folded. When the transmission rod 31 is rotatably engaged with the seat 2 and folds towards the frame 1, the transmission rod 31 drives the seat 2 to fold towards the frame 1, realizing the automatic folding of the seat 2. The drive mechanism 3 has a simple structure and is convenient for storing or unfolding the vehicle. Further optionally, when the transmission rod 31 is rotatably engaged with the frame 21 and folds towards the frame 1, the transmission rod 31 drives the frame 21 to fold towards the frame 1.

[0058] The drive unit 32 includes a drive motor, and the transmission rod 31 includes a lead screw 311 disposed on the drive motor and a lead screw nut 312 threadedly engaged with the lead screw 311. The lead screw nut 312 is rotatably disposed on the seat frame 2. In some other possible embodiments, the lead screw nut 312 can be slidably connected to the seat frame 2. In a specific implementation, the drive motor starts, drives the lead screw 311 to rotate, causing the lead screw nut 312 to move along the axial direction of the lead screw 311. During the movement, the lead screw 311 drives the drive motor to rotate relative to the vehicle frame 1, and the lead screw nut 312 rotates relative to the seat frame 2, causing the seat frame 2 to fold towards the vehicle frame 1, thus folding the vehicle in the first direction and reducing the size of the vehicle in the first direction.

[0059] The frame 2 also includes a support rod 22 disposed on the frame body 21. The support rod 22 extends in the left-right direction. A lead screw nut 312 is rotatably mounted on the support rod 22. The lead screw 311 extends in a direction perpendicular to the support rod 22. The lead screw 311 drives the frame body 21 to rotate toward the vehicle frame 1. In some other possible embodiments, the lead screw nut 312 is slidably connected to the support rod 22. In a specific implementation, the drive motor starts and drives the lead screw 311 to rotate, causing the lead screw nut 312 to move axially along the lead screw 311. During the movement, the lead screw 311 drives the drive motor to rotate relative to the vehicle frame 1, and the lead screw nut 312 rotates relative to the support rod 22, causing the frame body 21 to fold toward the vehicle frame 1, thus folding the vehicle in the first direction and reducing the size of the vehicle in the first direction.

[0060] In some embodiments, the transmission rod 31 is configured to cooperate with the seat plate 23 so that when the transmission rod 31 drives the frame 21 to fold towards the vehicle frame 1, the transmission rod 31 also drives the seat plate 23 to fold towards the frame 21, thereby further reducing the size of the vehicle in the first direction. The lead screw nut 312 of the transmission rod 31 is rotatably or slidably connected to the seat plate 23, and may be configured according to other connection structures.

[0061] The seat plate 23 is rotatably mounted on the frame 21. The end of the screw nut 312 away from the screw 311 is rotatably connected to the frame 21 so that when the vehicle is unfolded, the screw nut 312 and the frame 21 support the seat plate 23 at the same time, ensuring that the seat plate 23 can support the child.

[0062] Optionally, the lead screw nut 312 includes a nut component 3121 threadedly engaged with the lead screw 311 and a nut support tube 3122. The nut component 3121 is fixedly mounted on the nut support tube 3122, and the nut support tube 3122 is rotatably mounted on the support rod 22. The end of the nut support tube 3122 away from the lead screw 311 is rotatably connected to the seat plate 23. The lead screw 311 is threadedly connected to the nut component 3121. When the nut component 3121 moves along the axial direction of the lead screw 311, the lead screw 311 can be placed inside the nut support tube 3122. The nut support tube 3122 can serve to avoid and guide the lead screw 311.

[0063] Optionally, the nut support tube 3122 is rotatably mounted on the base plate 23 about the support tube rotation axis m3. The frame 21 is slidably connected to the base plate 23, and the base plate 23 is rotatably connected to the frame 21 about the frame rotation axis m4. The support tube rotation axis m3 is positioned relatively close to the front end of the base plate 23, and the frame rotation axis m4 is positioned relatively close to the rear end of the base plate 23. When the base plate 23 is folded in the first direction, the base plate 23 moves to the rear end. In the folded state of the vehicle, the base plate 23 is positioned further back, and the front end of the base plate 23 provides space for storing other components.

[0064] The aforementioned frame 21 includes a pair of seat rods 211 pivotally connected to the frame 1. Support rods 22 are positioned between the pair of seat rods 211 and rotatably connected to each seat rod 211. In the unfolded state, the seat rods 211, the frame 1, and the transmission rods 31 form a triangular structure, providing stable support for the seat frame 2 and ensuring that the seat frame 2 can stably support the child. Each connecting rod 81 is rotatably connected to the seat rod 211, and the seat rod 211 is rotatably connected to the first support 111.

[0065] In some other embodiments, the drive mechanism 3 is disposed on the frame 1 and drives the second bracket 112 to move closer to and fold towards the first bracket 111. The drive mechanism 3 includes a cylinder, the piston rod end of which is connected to the second bracket 112. When the piston rod extends, it can drive the second bracket 112 to unfold relative to the first bracket 111. When the piston rod retracts, it can drive the second bracket 112 to move closer to and fold towards the first bracket 111.

[0066] Of course, in the two driving methods of the driving mechanism 3 mentioned above, the driving mechanism 3 can also be other structures, which are not specifically limited here.

[0067] The aforementioned vehicle is a stroller, which also has a handle 7 mounted on the frame 1. The handle 7 can be folded towards the frame 1. Normally, the handle 7 is located at the rear of the vehicle. When folding, the handle 7 is folded forward to reduce the folded size of the vehicle in a second direction.

[0068] The vehicle is a stroller, with a seat or saddle on the seat plate 23 for infants and toddlers to sit on. A backrest 6 is rotatably connected to the seat plate 23, located at the rear end of the seat plate 23, and can be folded towards the frame 1. When folded, the backrest 6 is folded forward to reduce the folded size of the vehicle in a second direction.

[0069] When receiving the carrier provided in the application for the copy, such as Figure 5 and Figure 6 As shown, first fold the backrest 6 and the push handle 7. Figure 7 and Figure 8 As shown, the drive mechanism 3 drives the seat 2 to fold towards the frame 1, and at the same time drives the first wheel set 4 to fold towards the second wheel set 5. When the seat 2 folds towards the frame 1, the folding size of the vehicle in the first direction is reduced. When the first wheel set 4 folds towards the second wheel set 5, the folding size of the vehicle in the second direction is reduced. Figure 9 and Figure 10 This is a diagram showing the vehicle when it is fully folded up, with the distance between the first wheel group 4 and the second wheel group 5 reaching its minimum.
