[0048] like Figure 1 and Figure 2 As shown, this embodiment provides a vehicle including a frame 1, a seat 2, and a drive mechanism 3. The seat 2 is movably connected to the frame 1, and the drive mechanism 3 is movably connected to both the frame 1 and the seat 2. The drive mechanism 3 is used to drive the seat 2 to switch between unfolded and folded states. When the seat 2 is in the unfolded state, the drive mechanism 3 supports it between the seat 2 and the frame 1. When the seat 2 is in the folded state, the drive mechanism 3 drives the seat 2 to fold towards the frame 1. The drive mechanism 3 can automatically unfold or fold the seat 2, replacing manual unfolding or folding, which is simple to operate and convenient for users. When the seat 2 is unfolded, it is supported by the drive mechanism 3, ensuring that the seat 2 can support a child. The drive mechanism 3 provided in this embodiment serves multiple functions, including supporting the seat 2 and driving it to automatically unfold or fold.

[0049] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, 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 toward the frame 1, so that the transmission rod 31 can be rotated and folded. The transmission rod 31 is rotatably engaged with the seat frame 2, and when the transmission rod 31 moves toward the frame 1 and folds, the transmission rod 31 drives the seat frame 2 to move toward the frame 1 and fold, realizing the automatic folding of the seat frame 2. Moreover, the drive mechanism 3 has a simple structure and is convenient for storing or unfolding the vehicle.

[0050] Optionally, the drive component 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 frame 1, and the lead screw nut 312 rotates relative to the seat frame 2, causing the seat frame 2 to fold towards the frame 1, thus folding the vehicle in the first direction and reducing the size of the vehicle in the first direction.

[0051] The seat frame 2 has a frame body 21 rotatable on the frame 1 and a support rod 22 disposed on the frame body 21. The frame body 21 is rotatably mounted on the frame 1 about a first rotation axis m1, which extends in the left-right direction. A transmission rod 31 is rotatably engaged with the frame body 21, and when the transmission rod 31 moves towards the frame 1 and folds, the transmission rod 31 drives the frame body 21 to move towards the frame 1 and fold. In some other possible embodiments, the frame body 21 is slidably connected to the frame 1. The support rod 22 extends in the left-right direction, and a lead screw nut 312 is rotatably mounted on the support rod 22. The lead screw 311 extends entirely in a direction perpendicular to the support rod 22, and the lead screw 311 drives the frame body 21 to rotate towards the frame 1. In some other possible embodiments, the lead screw nut 312 is slidably connected to the support rod 22. In the specific implementation process, the drive motor starts and 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 frame 1, and the lead screw nut 312 rotates relative to the support rod 22, and drives the frame 21 to move closer to the frame 1 and fold, so that the vehicle is folded in the first direction, reducing the size of the vehicle in the first direction.

[0052] In some embodiments, the seat frame 2 further includes a seat plate 23 disposed on the frame body 21. The transmission rod 31 is configured to cooperate with the seat plate 23 so that when the transmission rod 31 drives the frame body 21 to fold towards the vehicle frame 1, the transmission rod 31 drives the seat plate 23 to fold towards the frame body 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 can be configured according to other connection structures.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] The frame 21 mentioned above includes a pair of seat rods 211 pivotally connected to the frame 1. A support rod 22 is disposed between the pair of seat rods 211 and is rotatably connected to the seat rods 211 respectively. In the unfolded state, the seat rods 211, the frame 1 and the transmission rod 31 form a triangular structure, which plays a role in providing stable support for the seat frame 2 and ensuring that the seat frame 2 can stably support the child.

[0057] In some embodiments, the frame 1 has a pair of side frames 11 disposed opposite to each other and a transverse support beam 12 connected between the pair of side frames 11. A drive member 32 is fixed to the transverse support beam 12, and the transverse support beam 12 is rotatably connected to each of the side frames 11. The frame body 21 is rotatably connected to the side frames 11. Further, one end of each of the two side frames 11 is rotatably connected to both ends of the transverse support beam 12, and the other end of each of the two side frames 11 is connected to a crossbeam. This crossbeam and the two side frames 11 are integrally formed and form a U-shaped structure. Optionally, the transverse support beam 12 is disposed opposite to each other near the rear side of the frame 1.

[0058] 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. The first wheel set 4 is connected to the side frame 11. 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.

[0059] 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.

[0060] The side frame 11 includes a first support 111 and a second support 112 rotatably connected. The seat frame 2 is rotatably connected to the first support 111. In the folded state, the seat frame 2 folds towards the first support 111. The second support 112 is rotatably connected to the first support 111, and the first wheel assembly 4 is fixedly connected to the second support 112. A linkage mechanism 8 is also connected between the second support 112 and the seat frame 2. In the folded state, the seat frame 2 drives the second support 112 to fold towards the first support 111 via the linkage mechanism 8, which in turn drives the first wheel assembly 4 to fold towards the second wheel assembly 5, reducing the folded size of the vehicle in a second direction.

[0061] The linkage mechanism 8 includes two connecting rods 81. One end of each connecting rod 81 is rotatably connected to a corresponding seat rod 211, and the other end of each connecting rod 81 is rotatably connected to a second bracket 112. The seat rod 211 is rotatably connected to the first bracket 111. When the seat rod 211 rotates relative to the first bracket 111, the seat rod 211 drives the connecting rod 81 to move, thereby driving the second bracket 112 to rotate, causing the first wheel set 4 to fold. Further, the frame body 21 is rotatably mounted on the first bracket 111 along the first rotation axis m1, specifically, the seat rod 211 is rotatably connected to the first bracket 111 along the first rotation axis m1. A portion of the frame body 21 extends to the other side of the first rotation axis m1 to form an extension, and the connecting rod 81 is pivotally connected to the extension.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] When receiving the carrier provided in the application for the copy, such as Figure 5 and Figure 6As 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.
