[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] See Figures 1-6 This embodiment provides a children's vehicle. This vehicle is a child-assisted bicycle, which is propelled by the child pushing off the ground with their feet while riding.

[0048] It should be noted that, Figure 4 and Figure 6 The directions shown are the actual directions relative to the child's position when the child is sitting in seat 6 and facing forward.

[0049] Compared to existing technologies that require children to turn the handlebars, the stroller in this embodiment requires less effort to steer during riding.

[0050] Specifically, the stroller includes a frame 1 and a front wheel assembly 2.

[0051] The frame 1 includes a frame body 12 and a steering handle 11 that rotates with the frame body 12.

[0052] The front wheel assembly 2 includes a front wheel bracket 21 and front wheels 22 rotatably mounted on both sides of the front wheel bracket 21. The steering armrest 11 is rotatably connected to the front wheel bracket 21, and when the steering armrest 11 swings in the left and right direction, it can drive the front wheel bracket 21 to rotate so as to achieve steering of the front wheels 22.

[0053] In this embodiment, when the stroller is in use, the child sits on the frame 1 and propels the stroller by pushing off the ground with both feet. When turning is required, since the child pushes off the ground with both feet, the child only needs to tilt their body left or right to cause the steering handle 11 to swing left and right. The steering handle 11 then drives the front wheel bracket 21 to rotate, thereby turning the front wheel 22.

[0054] The stroller provided in this embodiment allows children to turn the stroller simply by tilting their bodies, making the turning operation convenient and effortless.

[0055] It should be noted that the left-right swing of the steering armrest 11 means that the steering armrest 11 is swung to the left or right relative to the vertical plane. For example, tilting the steering armrest 11 to the left relative to the vertical plane means that the steering armrest 11 swings to the left; tilting the steering armrest 11 to the right relative to the vertical plane means that the steering armrest 11 swings to the right.

[0056] Specifically, the steering armrest 11 is rotatably mounted on the front wheel bracket 21 along the first rotating shaft 3, and the first rotating shaft 3 is inclined relative to the horizontal plane.

[0057] This configuration allows the steering armrest 11 to swing in the left and right directions, thereby driving the front wheel bracket 21 to rotate and thus enabling the front wheel 22 to steer.

[0058] Furthermore, the first pivot 3 is tilted forward and upward. This configuration allows the front wheel bracket 21 to rotate to the left when the steering armrest 11 swings to the left, thus enabling the front wheel 22 to turn left. Similarly, when the steering armrest 11 swings to the right, it allows the front wheel bracket 21 to rotate to the right, thus enabling the front wheel 22 to turn right.

[0059] Optionally, in this embodiment, the first rotating shaft 3 is tilted upwards at an angle of 20°-70° relative to the horizontal plane. For example, the angle of tilt of the first rotating shaft 3 relative to the horizontal plane is 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, or 70°. Preferably, the angle of tilt of the first rotating shaft 3 relative to the horizontal plane is 45°, at which point the steering operation is most smooth.

[0060] Furthermore, in this embodiment, the stroller also includes a rear wheel assembly 4.

[0061] The rear wheel assembly 4 includes a rear wheel bracket 41 and a rear wheel 42.

[0062] The rear wheel bracket 41 is rotatably engaged with the second rotating shaft 5, which extends along the front-rear direction of the frame 12.

[0063] The rear wheel 42 is mounted on the rear wheel bracket 41.

[0064] The first rotating shaft 3 and the second rotating shaft 5 are both located on the rotating shaft plane, which extends vertically. With this configuration, when the front wheel bracket 21 rotates, the frame 12 rotates along with the front wheel bracket 21, thereby driving the rear wheel bracket 41 to rotate, thus achieving steering of the rear wheel 42.

[0065] Furthermore, in this embodiment, the rear wheel bracket 41 includes a connecting arm 411 extending in the left-right direction and a support arm 412 extending in the front-back direction. The support arm 412 is fixed on the connecting arm 411 and extends in the axial direction of the second rotating shaft 5. The frame 12 rotates relative to the support arm 412.

[0066] Optionally, a rear wheel 42 is provided on the connecting arm 411. More optionally, a rear wheel 42 is provided at both ends of the connecting arm 411.

[0067] When the front wheel bracket 21 rotates, the frame 12 rotates along with the front wheel bracket 21, simultaneously driving the second rotating shaft 5 to rotate. The second rotating shaft 5 drives the support arm 412 to rotate, and the support arm 412 drives the connecting arm 411.

[0068] Furthermore, the support arm 412 extends forward from the outer wall of the connecting arm 411, and the connecting arm 411 extends entirely in the front-rear direction. This arrangement ensures the structural strength of the rear wheel bracket 41.

[0069] See Figures 1-4 In this embodiment, the steering armrest 11 includes a steering rod 111, a connector 112 disposed on the steering rod 111, and a handle 113. The connector 112 is provided with a pivot hole 1121, and the extension direction of the pivot hole 1121 is obliquely intersecting the extension direction of the steering rod 111.

[0070] When a child rides the tricycle, he holds the handlebars 113 with both hands and leans his body to the left, which causes the steering lever 111 to swing to the left. With the cooperation of the connector 112 and the first rotating shaft 3, the front wheel bracket 21 rotates to the left, and the front wheel 22 turns to the left, thus realizing the left turn of the whole vehicle.

[0071] When the child leans to the right, the steering lever 111 swings to the right. With the cooperation of the connector 112 and the first rotating shaft 3, the front wheel bracket 21 rotates to the right, and the front wheel 22 turns to the right, thus realizing the right turn of the whole vehicle.

[0072] Further, see Figure 2 and Figure 3The front wheel bracket 21 is provided with a clearance notch 214. The first rotating shaft 3 is fixedly mounted on the front wheel bracket 21 and located within the clearance notch 214. The connector 112 at the lower end of the steering armrest 11 is rotatably connected to the first rotating shaft 3. The two opposite sides of the clearance notch 214 can limit the swing range of the steering armrest 11, ensuring the safety of children when turning.

[0073] Specifically, the front wheel bracket 21 includes a left front wheel axle 215 and a right front wheel axle 211 arranged coaxially. A connecting block 212 is provided between the left front wheel axle 215 and the right front wheel axle 211. The first rotating shaft 3 is fixedly installed on the connecting block 212. The left front wheel axle 215, the right front wheel axle 211 and the connecting block 212 surround and form an avoidance gap 214.

[0074] Optionally, the connecting block 212 has a cylindrical structure.

[0075] A front wheel 22 is provided at the free end of both the left front axle 215 and the right front axle 211.

[0076] Optionally, in this embodiment, the connector 112 has a cylindrical structure, which is configured such that the connector 112 and the side of the clearance notch 214 are in line contact, thus avoiding the difficulty of tilting the connector 112 due to the surface contact method.

[0077] Furthermore, in order to prevent the connector 112 from detaching from the first rotating shaft 3, after the connector 112 is installed on the first rotating shaft 3, a locking part is provided at the end of the connector 112 away from the connecting block 212.

[0078] Further, see Figure 3 To prevent interference between the steering armrest 11 and the front wheel bracket 21 during steering, a first clearance recess 213 is provided on both sides of the clearance notch 214 on the front wheel bracket 21; and / or

[0079] A second avoidance ramp 114 is provided on both sides of the avoidance notch 214 on the steering rod 111 of the steering handrail 11.

[0080] More specifically, in this embodiment, the front wheel bracket 21 is provided with a first clearance concave surface 213 on both sides of the clearance notch 214, and the steering rod 111 of the steering armrest 11 is provided with a second clearance ramp 114 on both sides of the clearance notch 214.

[0081] Specifically, in this embodiment, the frame 12 includes an upper tube 121 and a front tube 122.

[0082] The upper tube 121 extends in the front-to-back direction, and a seat 6 is provided on the upper tube 121.

[0083] The front tube 122 is located at one end of the upper tube 121, and the steering armrest 11 is rotatably engaged with the front tube 122.

[0084] Furthermore, the frame 12 also includes a riser 123, the upper end of which is connected to the end of the upper pipe 121 away from the front pipe 122, and the lower end of the riser 123 is provided with a second pivot 5.

[0085] Preferably, in this embodiment, the seat 6 is connected to the rear wheel assembly 4, and the mounting position of the seat 6 on the upper tube 121 is adjustable front and rear.

[0086] Specifically, the seat 6 is fixedly installed at the upper end of the riser tube 123, the upper end of the riser tube 123 is connected to the upper tube 121 through the seat 6, and the lower end of the riser tube 123 is connected to the rear wheel assembly 4 through the second pivot 5.

[0087] Specifically, the upper tube 121 is provided with a use position and a storage position. The seat 6 can be adjusted to the use position or the storage position. The use position is located away from the steering armrest 11, and the storage position is located close to the steering armrest 11.

[0088] Specifically, see Figure 7 , Figure 7 The middle carriage seat 6 is used on the upper tube 121. Figure 8 In the middle, the seat 6 is stored on the upper tube 121.

[0089] Furthermore, the stroller also includes a seat lock that can lock the seat 6 onto the upper tube 121.

[0090] When the seat 6 is in the use position of the top tube 121, the seat locking device can be connected to both the seat 6 and the top tube 121 to lock the seat 6 onto the top tube 121, preventing the seat 6 from shifting and causing a safety accident while the child is riding.

[0091] Optionally, in this embodiment, the seat locking component includes a bolt and a nut.

[0092] When the seat 6 is in the use position of the upper tube 121, the bolt of the seat locking member passes through the seat 6 and the upper tube 121 and is locked by the nut, so that the position of the seat 6 can no longer be moved.

[0093] Optionally, multiple usage positions can be set on the upper tube 121 to accommodate children with different arm lengths.

[0094] 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.
