Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a children's vehicle. Background Art

[0002] Currently, some child carriers on the market, such as strollers, feature a driver-reversing feature, allowing the driver to change the stroller's direction of travel. However, before the driver turns forward, the child's center of gravity is closer to the rear wheel. After the driver turns forward, the child's center of gravity remains unchanged, and is closer to the front wheel after the change of direction (i.e., the rear wheel that turned forward). This makes pushing the stroller difficult, and the center of gravity height cannot be adjusted as needed, resulting in a poor user experience. Summary of the Invention

[0003] Based on this, it is necessary to provide a child carrier that can change the center of gravity when the rider turns, so that the user can adjust the center of gravity of the rider as needed, which is convenient for travel and provides a better user experience.

[0004] A child carrier is characterized in that it includes a frame, a rider and a riding member, wherein the rider is pivotally connected to the frame, the riding member is used to support a seat, and the rider is used to rotate relative to the frame to drive the riding member to move from a first position to a second position relative to the frame.

[0005] The rider's handle rotates relative to the frame, causing the seating member to move relative to the frame from a first position to a second position. Since the seating member supports the seat, this is equivalent to the movement of the child and the seat in the child carrier, i.e., the center of gravity of the entire child carrier. Thus, the user can rotate the rider's handle to adjust the center of gravity of the child carrier as needed, shifting it rearward after a change of direction for easier pushing, shifting it upward to reduce the child's exposure to vehicle exhaust, or shifting it downward to provide greater overall stability.

[0006] In one embodiment, the bicycle frame includes a support rod, the riding member is slidably disposed on the support rod, and the rider rotates to drive the riding member to move along the support rod.

[0007] In one embodiment, the support rod is arranged along a first direction, and the rider is used to rotate relative to the frame to change the moving direction of the frame from the first direction to the second direction, and at the same time drive the riding member to move from a first position to a second position relative to the frame, and the second position is located in the first direction of the first position.

[0008] In one embodiment, the child carrier further includes a first linkage assembly, and when the rider rotates, the riding member is driven to move along the support rod through the first linkage assembly.

[0009] In one embodiment, the first linkage assembly includes a rotating member and a driving member, one end of the rotating member is fixedly connected to the rider, the other end of the rotating member is pivotally connected to one end of the driving member, and the other end of the driving member is pivotally connected to the riding member.

[0010] In one embodiment, the rotating member and the driving member are both located above the riding member.

[0011] In one embodiment, the child carrier further includes a rotating shaft, which is fixed to the rider and passes through the frame to pivotally connect the rider to the frame, and one end of the rotating member is fixed to the rotating shaft.

[0012] In one embodiment, the rider includes a rider fixing seat, and the rotating shaft is fixedly connected to the rider fixing seat.

[0013] In one embodiment, the riding member is slidably mounted on the support rod.

[0014] In one embodiment, a plurality of pulleys are provided inside the riding member and abut against the support rods.

[0016] In one embodiment, the child carrier further includes a second linkage assembly, the frame includes a support rod, the riding member is connected to the support rod via the second linkage assembly, and the rider rotates to drive the riding member to move relative to the support rod.

[0017] In one embodiment, the support rod is arranged along a first direction, and the rider is used to rotate relative to the frame to change the travel direction of the frame from the first direction to a second direction, and simultaneously drive the riding member to move relative to the frame from a first position to a second position, and the second position is located in the first direction of the first position; or

[0050] like Figure 1 and Figure 2 As shown, the present invention provides a child carrier 10, such as a child stroller. The child carrier 10 includes a frame 100, a rider 200, and a seat 300. The child carrier 10 can shift its center of gravity according to user needs when the rider 200 rotates, facilitating travel and providing a better user experience.

[0051] Specifically, if Figures 1 to 4 As shown, the rider 200 is pivotally connected to the frame 100, and the riding member 300 is used to support the seat (not shown in the drawings). The rider 200 is used to rotate relative to the frame 100 to convert the travel direction of the frame 100 from the first direction D1 to the second direction D2, and at the same time drive the riding member 300 to move from the first position to the second position relative to the frame 100. The second position is located in the first direction D1 of the first position. The first direction D1 can be, for example, Figure 1 The horizontal left direction shown in FIG. 1 , the second direction D2 can be, for example, Figure 1In the horizontal rightward direction shown, based on the direction of travel after the change of direction, the second position is equivalent to being located behind the first position. That is, when the rider 200 rotates to change the direction of travel of the frame 100 from the first direction D1 to the second direction D2, the seating member 300 moves rearward. Since the seating member 300 supports the seat, this is equivalent to the child and the seat in the child carrier 10 moving rearward, that is, the center of gravity of the entire child carrier 10 moves rearward. This reduces the rider 200's effort in pushing the child carrier 10 after the change of direction. Alternatively, the rider 200 can rotate relative to the frame 100 to move the seating member 300 from the first position to a second position relative to the frame 100, the second position being located above or below the first position. The second position being located above the first position, that is, the center of gravity of the child carrier 10 moves upward. This allows the child in the child carrier 10 to ride higher, reducing the child's exposure to exhaust fumes such as vehicle exhaust, 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 carrier 10 moves downward, so that the child carrier 10 as a whole is more stable and the safety performance of the child carrier 10 is improved.

[0052] Specifically, if Figure 5 and Figure 6 As shown, the frame 100 includes a support rod 110, a first wheel support member 120, and a second wheel support member 130. One end of the first wheel support member 120 and the second wheel support member 130 are connected to a first wheel 140 and a second wheel 150, respectively. The other ends of the first wheel support member 120 and the second wheel support member 130 are fixedly connected to form a generally triangular support structure. The support rod 110 is connected between the first wheel support member 120 and the second wheel support member 130. In this embodiment, the rider 200 is pivotally connected to the support rod 110. Of course, in other embodiments, the rider 200 can also be pivotally connected to the first wheel support member 120 or the second wheel support member 130.

[0053] In one embodiment, Figures 1 to 16As shown, the child carrier 10 further includes a first linkage assembly 400, a rotating shaft 500, a fixing plate 600, and a reinforcing plate 700. The passenger member 300 is slidably mounted on the support rod 110, and the rider 200 rotates to drive the passenger member 300 along the support rod 110. Specifically, the rider 200 rotates, simultaneously driving the passenger member 300 along the support rod 110 via the first linkage assembly 400. In this embodiment, the passenger member 300 has a sliding sleeve structure, slidably mounted on the support rod 110. Furthermore, the passenger member 300 is internally provided with a plurality of pulleys that abut against the support rod 110. This reduces sliding friction between the passenger member 300 and the support rod 110, allowing the passenger member 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 the pulleys can also be adjusted as needed.

[0054] Specifically, if Figure 7 and Figure 8 As shown, the first linkage assembly 400 may include a rotating member 410 and a driving member 420. Figure 8 As shown, the driving member 420 is generally elliptical and circular. In this embodiment, the rotating member 410 and the driving member 420 are both located above the passenger member 300, with the center of the circular arc of the driving member 420 located below the circular arc. Of course, in other embodiments, the rotating member 410 and the driving member 420 may also be located below the passenger member 300.

[0055] In this embodiment, 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 arranged horizontally, and the second rod 112 is arranged at an angle to the first rod 111, specifically at an obtuse angle. The rider 200 is pivoted 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 pivoted to one end of the driving member 420. The other end of the driving member 420 is pivoted to the riding member 300. In this way, Figure 13 and Figure 14As shown, the three pivotally connected and movable parts, namely the rotating member 410, the driving member 420, and the riding member 300, form a connecting rod-like structure. When the rider 200 rotates in the third direction D3, the rotating member 410 and the driving member 420 rotate under the traction of the rider 200, thereby pulling the riding member 300 to move along the support rod 110. Because the riding member 300 always moves in the direction of movement of the rider 200, and the rider 200 is always on the same side as the wheel located in the rearward direction of travel, the rotation of the rider 200 automatically drives the riding member 300 to move rearward along the support rod 110 in the direction of travel, i.e., the center of gravity of the entire child carrier 10 shifts rearward. This makes it easier for the rider 200 to push the child carrier 10 after changing direction.

[0056] Further, if Figure 5 、 Figure 9 and Figure 10 As shown, the rotating shaft 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 rotating shaft 500. In this way, the rider 200 is pivotally connected to the frame 100 via the rotating shaft 500, and when the rider 200 rotates, the rotating member 410 can be driven to rotate via the rotating shaft 500, thereby achieving movement of the riding member 300.

[0057] Further, if Figure 5 、 Figure 9 and Figure 10 As shown, the driver 200 may further include a driver mounting base 210 at the end. The rotating shaft 500 is fixedly connected to the driver mounting base 210, and the connection between the two may be strengthened by a fixing plate 600. The fixing plate 600 may specifically be in the shape of a partial gear. The rotating shaft 500 is inserted and fixed in the center hole of the partial gear, and the edge of the partial gear is fixedly connected to the driver 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 driver mounting base 210. Of course, in other embodiments, other connection methods may also be used, and this is not limited here.

[0058] Further, if Figure 15 and Figure 16 As shown, the reinforcing sheet 700 is coated on 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 coated on 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.

[0059] In another embodiment, Figures 17 to 25As shown, the child carrier 10 further includes a second linkage assembly 800 and a rotating shaft 500. The riding member 300 is connected to the support rod 110 via the second linkage assembly 800. The rotation of the rider 200 drives the riding member 300 to move relative to the support rod 110. In this way, the rotation of the rider 200 simultaneously changes the center of gravity of the child carrier 10.

[0060] Specifically, if 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, the other end of the first link 810 is pivotally connected to one end of the riding member 300, the other end of the riding member 300 is pivotally connected to one end of the second link 820, the other end of the second link 820 is pivotally connected to the support rod 110, and the first link 810, the riding member 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 riding member 300 and the second link 820 are all located above the support rod 110. Of course, in other embodiments, the first link 810, the riding member 300 and the second link 820 may also be located below the support rod 110. In this way, on the one hand, as Figure 17 and Figure 18 As shown, when the rider 200 rotates in the third direction D3, the first connecting rod 810, the riding member 300 and the second connecting rod 820 rotate and move under the traction of the rider 200. Since the riding member 300 always moves in the direction of movement of the rider 200 under the drive of the rider 200, and the rider 200 is always on the same side as the wheel located behind the direction of travel, when the rider 200 rotates and changes direction, the riding member 300 can be automatically driven to move along the support rod 110 to the rear of the direction of travel, that is, the center of gravity of the entire child carrier 10 moves backward, so that the rider 200 can push the child carrier 10 with less effort after changing direction. On the other hand, Figure 18 and Figure 19 As shown, because the first link 810, the riding member 300, the second link 820, and the support rod 110 are sequentially connected to form a deformable quadrilateral structure, when the rider 200 rotates, the distance between the riding member 300 and the support rod 110 also changes, that is, the height of the riding member 300 changes, and thus the center of gravity height of the child carrier 10 also changes. In this way, the user can adjust the center of gravity height of the child carrier 10 as needed by rotating the rider 200.

[0061] Specifically, if Figure 21 、 Figure 23 and Figure 25As shown, the rotating shaft 500 is fixed to the rider 200 and passes through the frame 100 so that the rider 200 is pivotally connected to the frame 100. One end of the rotating member 410 is fixed to the rotating shaft 500. In this way, the rider 200 is pivotally connected to the frame 100 through the rotating shaft 500, and when the rider 200 rotates, the rotating member 410 can be driven to rotate through the rotating shaft 500, thereby realizing the movement of the riding member 300. In this embodiment, as shown in FIG. Figure 26 As shown, the cross section of the rotating shaft 500 is substantially square, and a through hole (not shown in the drawings) is provided on the rotating member 410 , and the rotating shaft 500 is passed through the through hole and has an interference fit with the through hole.

[0062] The above-mentioned child carrier 10 has at least the following technical effects:

[0063] The rider 200 rotates relative to the frame 100, causing the seating member 300 to move relative to the frame 100 from a first position to a second position. Since the seating member 300 supports the seat, this is equivalent to the movement of the child and the seat in the child carrier 10, i.e., the center of gravity of the entire child carrier 10. Thus, the user can rotate the rider 200 to adjust the center of gravity of the child carrier 10 as needed, such as shifting the center of gravity of the child carrier 10 rearward after changing direction, making it easier to push, shifting the center of gravity of the child carrier 10 upward to reduce the child's exposure to vehicle exhaust, or shifting the center of gravity of the child carrier 10 downward to make the child carrier 10 more stable overall.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0065] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
