[0001] Divisional application statement

[0002] This application is a divisional application of Chinese invention patent application filed on October 20, 2021, entitled "Children's Vehicle" and with application number 202111223148.8. Technical Field

[0003] This invention relates to the technical field of vehicles, and in particular to a child vehicle. Background Technology

[0004] Currently, some child vehicles on the market, such as strollers, have a driver-switching function, meaning the stroller's direction of travel is changed by switching the driver's position. However, when the driver is not switching positions, the child's center of gravity is closer to the rear wheel. After switching positions, the child's center of gravity does not change, and it is now closer to the front wheel (the rear wheel after switching positions). Pushing the stroller in this situation is very difficult, and the stroller's center of gravity height cannot be adjusted as needed, resulting in a poor user experience. Summary of the Invention

[0005] Therefore, it is necessary to provide a child vehicle that can shift the center of gravity when the rider turns, allowing the user to adjust the position of the rider's center of gravity as needed, making travel more convenient and providing a better user experience.

[0007] The rider rotates relative to the frame, causing the seat to move from a first position to a second position relative to the frame. Since the seat supports the seat, this is equivalent to the child and seat moving within the child vehicle, thus shifting the center of gravity of the entire child vehicle. The user can then rotate the rider as needed to adjust the child vehicle's center of gravity, making it easier to push, raising it to reduce the child's absorption of exhaust fumes, or lowering it for greater stability.

[0052] like Figure 1 and Figure 2 As shown, the present invention proposes a child vehicle 10, such as a stroller. The child vehicle 10 includes a frame 100, a handlebar 200, and a seat 300. The child vehicle 10 can change its center of gravity position according to the user's needs when the handlebar 200 rotates, making it convenient for travel and providing a better user experience.

[0053] Specifically, such as Figures 1 to 4 As shown, the rider 200 is pivotally connected to the frame 100, and the seat 300 supports the seat (not shown in the attached diagram). The rider 200 rotates relative to the frame 100 to change the direction of travel of the frame 100 from a first direction D1 to a second direction D2, and simultaneously moves the seat 300 relative to the frame 100 from a first position to a second position. The second position is located in the first direction D1 of the first position. The first direction D1 can be, for example, as shown in the attached diagram. Figure 1 The horizontal leftward direction shown, the second direction D2 could be, for example, as shown below. Figure 1As shown, in the horizontal rightward direction, with the direction of travel after the reversal as the reference, the second position is equivalent to being behind the first position. That is, when the rider 200 rotates to change the travel direction of the frame 100 from the first direction D1 to the second direction D2, the position of the seat 300 moves backward. Since the seat 300 is used to support the seat, it is equivalent to the child and seat in the child vehicle 10 moving backward, that is, the center of gravity of the entire child vehicle 10 shifts backward. In this way, it is easier for the rider 200 to push the child vehicle 10 after the reversal. Alternatively, the rider 200 can also be used to rotate relative to the frame 100 to move the seat 300 relative to the frame 100 from the first position to the second position, which is located above or below the first position. The second position is above the first position, that is, the center of gravity of the child vehicle 10 shifts upward. In this way, the child sitting in the child vehicle 10 can sit at a higher height, reducing the child's absorption of exhaust fumes and other exhaust gases, which is beneficial to the child's health. The second position is located below the first position, that is, the center of gravity of the child vehicle 10 is lowered. This makes the child vehicle 10 more stable as a whole and improves the safety performance of the child vehicle 10.

[0054] Specifically, such as Figure 5 and Figure 6 As shown, the frame 100 includes a support rod 110, a first wheel support 120, and a second wheel support 130. One end of the first wheel support 120 and the second wheel support 130 are respectively connected to the first wheel 140 and the second wheel 150, and the other ends of the first wheel support 120 and the second wheel support 130 are fixedly connected to form a generally triangular support structure. The support rod 110 is connected between the first wheel support 120 and the second wheel support 130. In this embodiment, the rider 200 is pivotally connected to the support rod 110. Of course, in other embodiments, the rider 200 may also be pivotally connected to the first wheel support 120 or the second wheel support 130.

[0055] In one embodiment, such as Figures 1 to 16As shown, the child vehicle 10 also includes a first linkage assembly 400, a rotating shaft 500, a fixing plate 600, and a reinforcing plate 700. The seating component 300 is slidably mounted on the support rod 110, and the rider 200 rotates to move the seating component 300 along the support rod 110. Specifically, the rider 200 rotates, simultaneously moving the seating component 300 along the support rod 110 via the first linkage assembly 400. In this embodiment, the seating component 300 has a sliding sleeve structure, slidably mounted on the support rod 110. Furthermore, the seating component 300 has multiple pulleys inside that abut against the support rod 110. This reduces the sliding friction between the seating component 300 and the support rod 110, allowing the seating component 300 to move more smoothly along the support rod 110. In this embodiment, there are four pulleys, two of which abut against the upper side of the support rod 110, and the other two abut against the lower side of the support rod 110. Of course, in other embodiments, the number and arrangement of pulleys can also be adjusted as needed.

[0056] Specifically, such as Figure 7 and Figure 8 As shown, the first linkage assembly 400 may include a rotating member 410 and a driving member 420. For example... Figure 8 As shown, the drive member 420 is generally elliptical in shape and generally arc-shaped in shape. In this embodiment, both the rotating member 410 and the drive member 420 are located above the seating member 300, and the center of the arc-shaped structure of the drive member 420 is located below the arc-shaped structure. Of course, in other embodiments, both the rotating member 410 and the drive member 420 may be located below the seating member 300.

[0057] In this embodiment, as Figure 6 As shown, the support rod 110 includes a first rod 111 and a second rod 112 connected to each other. The first rod 111 is horizontally positioned, and the second rod 112 is positioned at an angle to the first rod 111, specifically at an obtuse angle. The rider 200 is pivotally connected to the second rod 112. One end of the rotating member 410 is fixedly connected to the rider 200, and the other end of the rotating member 410 is pivotally connected to one end of the driving member 420. The other end of the driving member 420 is pivotally connected to the riding member 300. Thus, as... Figure 13 and Figure 14As shown, the three pivotally connected and movable parts—rotating component 410, driving component 420, and riding component 300—form a linkage-like structure. When the rider 200 rotates in the third direction D3, the rotating component 410 and driving component 420 rotate under the traction of the rider 200, thereby pulling the riding component 300 along the support rod 110. Since the riding component 300 always moves in the direction of the rider 200's movement under the rider 200's influence, and the rider 200 is always on the same side as the wheel located behind in the direction of travel, the rotation of the rider 200 automatically drives the riding component 300 to move behind in the direction of travel along the support rod 110. This shifts the center of gravity of the entire child vehicle 10 backward, making it easier for the rider 200 to push the child vehicle 10 after changing direction.

[0058] Furthermore, such as Figure 5 , Figure 9 and Figure 10 As shown, the pivot 500 is fixed to the rider 200 and passes through the frame 100 to pivotally connect the rider 200 to the frame 100. One end of the rotating member 410 is fixed to the pivot 500. In this way, the rider 200 is pivotally connected to the frame 100 through the pivot 500, and when the rider 200 rotates, it can drive the rotating member 410 to rotate through the pivot 500, thereby realizing the movement of the seat 300.

[0059] Furthermore, such as Figure 5 , Figure 9 and Figure 10 As shown, the rider 200 may further include a rider mounting base 210 located at the end, with the rotating shaft 500 fixedly connected to the rider mounting base 210, and the connection between the two can be strengthened by a fixing plate 600. Specifically, the fixing plate 600 may be partially gear-shaped, with the rotating shaft 500 inserted and fixed in the center hole of the partially gear, and the edge of the partially gear fixedly connected to the rider mounting base 210. In this embodiment, the wall of the center hole of the fixing plate 600 is welded to the rotating shaft, and the edge of the fixing plate 600 is welded to the rider mounting base 210. Of course, other connection methods may be used in other embodiments, and are not limited here.

[0060] Furthermore, such as Figure 15 and Figure 16 As shown, the reinforcing sheet 700 covers one side of the rotating member 410 to ensure the strength of the rotating member 410. In this embodiment, the reinforcing sheet 700 is an iron sheet covering the inner side of the rotating member 410. Of course, in other embodiments, the reinforcing sheet 700 can also be of other forms or materials.

[0061] In another embodiment, such as Figures 17 to 25As shown, the child vehicle 10 also includes a second linkage assembly 800 and a pivot 500. The seat 300 is connected to the support rod 110 via the second linkage assembly 800, and the rider 200 rotates to move the seat 300 relative to the support rod 110. Thus, the rotation of the rider 200 can simultaneously change the center of gravity position of the child vehicle 10.

[0062] Specifically, such as Figures 22 to 26 As shown, the second linkage assembly 800 may include a first link 810 and a second link 820. One end of the first link 810 is fixedly connected to the rider 200, and the other end of the first link 810 is pivotally connected to one end of the seat 300. The other end of the seat 300 is pivotally connected to one end of the second link 820, and the other end of the second link 820 is pivotally connected to the support rod 110. The first link 810, the seat 300, the second link 820, and the support rod 110 are sequentially connected to form a deformable quadrilateral structure. In this embodiment, the first link 810, the seat 300, and the second link 820 are all located above the support rod 110. Of course, in other embodiments, the first link 810, the seat 300, and the second link 820 may also be located below the support rod 110. Thus, on the one hand, as... Figure 17 and Figure 18 As shown, when the rider 200 turns in the third direction D3, the first link 810, the seat 300, and the second link 820 will rotate and move under the traction of the rider 200. Since the seat 300 always moves in the direction of the rider 200's movement, and the rider 200 is always on the same side as the wheel located behind in the direction of travel, the rider 200 can automatically move the seat 300 along the support rod 110 to the rear in the direction of travel when turning to change direction. This shifts the center of gravity of the entire child vehicle 10 backward, making it easier for the rider 200 to push the child vehicle 10 after changing direction. On the other hand, as... Figure 18 and Figure 19 As shown, since the first link 810, the seat 300, the second link 820, and the support rod 110 are sequentially connected to form a deformable quadrilateral structure, the distance between the seat 300 and the support rod 110 changes when the rider 200 rotates, meaning the height of the seat 300 changes, and consequently, the center of gravity of the child vehicle 10 changes. Thus, the user can rotate the rider 200 to adjust the center of gravity of the child vehicle 10 as needed.

[0063] Specifically, such as Figure 21 , Figure 23 and Figure 25As shown, the pivot 500 is fixed to the rider 200 and passes through the frame 100 to pivotally connect the rider 200 to the frame 100. One end of the rotating member 410 is fixed to the pivot 500. Thus, the rider 200 is pivotally connected to the frame 100 via the pivot 500, and when the rider 200 rotates, it can drive the rotating member 410 to rotate via the pivot 500, thereby enabling the movement of the seat 300. In this embodiment, as... Figure 26 As shown, the cross-section of the rotating shaft 500 is approximately square, and the rotating component 410 is provided with a through hole (not shown in the attached figure). The rotating shaft 500 passes through the through hole and is interference-fitted with the through hole.

[0064] The aforementioned child vehicle 10 has at least the following technical effects:

[0065] The rider 200 rotates relative to the frame 100, causing the seat 300 to move from a first position to a second position relative to the frame 100. Since the seat 300 is used to support the seat, this is equivalent to the child and seat in the child vehicle 10 moving, i.e., the center of gravity of the entire child vehicle 10 shifting. Thus, the user can rotate the rider 200 as needed to adjust the center of gravity of the child vehicle 10, making the center of gravity of the child vehicle 10 shift backward after reversing direction, making it easier to push, or shifting the center of gravity of the child vehicle 10 upward to reduce the child's absorption of car exhaust fumes, or shifting the center of gravity of the child vehicle 10 downward to make the child vehicle 10 more stable overall.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
