Detailed Implementation

[0019] like Figures 1 to 4 As shown, a children's vehicle wheel includes a hub body 10, a tire 20, and a bearing seat 30. The tire 20 is fitted onto the outer edge of the hub body 10, and the bearing seat 30 is installed in the middle of the hub body 10. The structure is simple and easy to install.

[0020] In specific implementation, the wheel hub body 10 includes a first wheel hub shell 11 and a second wheel hub shell 12. The first wheel hub shell 11 and the second wheel hub shell 12 are connected to each other. The outer edge of the first wheel hub shell 11 is recessed with a circular first mounting groove 111, and the outer edge of the second wheel hub shell 12 is recessed with a circular second mounting groove 121. The inner edge of the tire 20 is protruded with a circular tire ring 21. The tire ring 21 is fitted into the first mounting groove 111 and the second mounting groove 121. The side of the tire ring 21 is evenly provided with a plurality of mounting through holes 211. The inner side of the first mounting groove 111 is evenly provided with a plurality of first fixing through holes 112, and the inner side of the second mounting groove 121 is evenly provided with a plurality of second fixing through holes 112. Through-post 122, several first fixed through-posts 112 and several second fixed through-posts 122 are inserted into several mounting through-holes 211 and connected and fixed by fasteners passing through the first fixed through-posts 112 and the second fixed through-posts 122, so that the vehicle tire 20 can be detachably mounted on the outer edge of the wheel hub body 10. In use, if the vehicle tire 20 needs to be replaced due to wear or damage, the user only needs to remove the fasteners to separate the first wheel hub housing 11 and the second wheel hub housing 12. The tire convex ring 21 can then be removed from the first mounting slot 111 and the second mounting slot 121. After replacing the vehicle tire, the first fixed through-posts 112 and the second fixed through-posts 122 are re-inserted and locked by fasteners to complete the vehicle tire replacement operation. This structure not only allows for easy removal and replacement of the tires, but also ensures the stability of the connection between the tire and the wheel hub body when the wheel is in normal use, through the locking fit of the slot and the fastener locking fit, thus preventing the tire from loosening or falling off during rolling.

[0021] In practical implementation, the inner side of the first hub housing 11 is uniformly recessed with a plurality of first bearing slots 113, and the inner side of the second hub housing 12 is uniformly recessed with a plurality of second bearing slots 123. The plurality of first bearing slots 113 and the plurality of second bearing slots 123 are arranged opposite to each other. The outer edge of the bearing seat 30 is uniformly provided with a plurality of bearing connecting rods 31, and the ends of the plurality of bearing connecting rods 31 are provided with mounting clips 311. The left and right sides of the mounting clips 311 are symmetrically provided with fixing blocks 3. 12. The first bearing slot 113 has symmetrically recessed first fixing grooves 114 on its left and right sides, and the second bearing slot 123 has symmetrically recessed second fixing grooves 124 on its left and right sides. During installation, the mounting part 311 connects between the first bearing slot 113 and the second bearing slot 123, while the fixing block 312 engages with the first fixing groove 114 and the second fixing groove 124 to achieve a locking fixation, thereby securing the bearing seat 30 firmly in the middle of the wheel hub body 10. In use, the wheel rotates through the bearing seat 30 in conjunction with the axle on the stroller frame. The ball bearing rotates within the bearing seat, effectively reducing frictional resistance and improving the wheel's flexibility and smoothness. Because the bearing seat 30 is limited and fixed through the engagement of the mounting part 311 and the fixing block 312, it can maintain stability during long-term rolling, preventing displacement or loosening, thus improving the wheel's service life and safety.

[0022] In practical implementation, the inner surface of the first wheel hub housing 11 is uniformly recessed with a plurality of positioning grooves 115, and the inner surface of the second wheel hub housing 12 is uniformly protruded with a plurality of positioning protrusions 125. When the first wheel hub housing 11 and the second wheel hub housing 12 are connected relative to each other, the plurality of positioning protrusions 125 are correspondingly engaged in the plurality of positioning grooves 115 to achieve positioning connection. In use, the engagement of the positioning protrusions 125 and the positioning grooves 115 can ensure that the first wheel hub housing 11 and the second wheel hub housing 12 are quickly aligned during assembly, avoiding offset or misalignment, thereby improving the convenience and accuracy of installation. At the same time, after the vehicle tire 20 is installed on the wheel hub body 10, the limiting effect between the positioning protrusions 125 and the positioning grooves 115 can further enhance the stability between the two housings, preventing loosening between the housings due to vibration or external force during wheel rolling, ensuring the overall robustness of the wheel structure and the safety of use.

[0023] In practical implementation, the bearing housing 30 has a mounting through part 32 in the middle, and a positioning through part 33 is connected to the side of the mounting through part 32. The side of the mounting through part 32 is evenly recessed with a plurality of connecting recesses 321, and the side of the positioning through part 33 is evenly protruded with a plurality of connecting protrusions 331. The plurality of connecting protrusions 331 are fitted into the plurality of connecting recesses 321 in a corresponding manner and engaged. In use, the mounting through part 32 provides a through passage for the axle. The positioning through part 33, through the engagement of the connecting protrusions 331 and the connecting recesses 321, precisely limits the position of the mounting through part 32, thereby improving the overall structural strength and safety.

[0024] In summary, this utility model, through the reasonable cooperation of the wheel hub body 10, the tire 20, and the bearing seat 30, enables the tire 20 to be easily disassembled and replaced via the mounting slots, fixing pins, and fasteners of the first wheel hub housing 11 and the second wheel hub housing 12, thereby reducing maintenance costs and improving ease of use. The positioning protrusions and positioning grooves between the wheel hub housings ensure that the housings are quickly aligned and firmly fixed during assembly, preventing misalignment and improving the overall structural reliability. Users can replace tires with different materials or tread patterns as needed to enhance anti-slip and shock absorption performance, adapt to various road conditions, and improve the comfort and user experience of the stroller.
