Description

Technical Field

[0001] This utility model relates to the field of children's balance bikes, and in particular to a balance bike anti-tipping and stable support structure. Background Technology

[0002] Children's balance bikes are mainly designed for toddlers to improve their balance. Children need to continuously push off the ground with their feet to provide gliding power, and the balance of the balance bike also requires children to keep their feet on the ground to maintain balance.

[0003] Chinese Patent No. CN219904580U discloses a self-balancing scooter with an anti-rollover component, including a main frame, a seat and handlebars fixedly connected to the main frame, a front wheel and a rear wheel rotatably connected to the main frame, a collar rotatably connected to the handlebars, a protective frame fixedly connected to the collar, connecting nuts connected to both ends of the handlebars, and a support mechanism for preventing the self-balancing scooter from rolling over connected to the other end of the protective frame. The support mechanism includes the self-balancing frame. This utility model utilizes a balance frame to ensure the main frame structure of the vehicle remains vertical. When the moving rollers on the balance frame touch the ground, the structure forms a triangular structure with the front wheel, ensuring that the overall structure will not tip over and has stability. However, in the aforementioned patent, when the balance frame is used to assist in balancing the balance vehicle, the balance frame and protective frame are relatively large and take up space, which will cause inconvenience for children when getting on and off the balance vehicle. Furthermore, once children are proficient in balancing, it is difficult to fold and store the balance frame and protective frame when anti-tipping is no longer needed, which will cause inconvenience for children riding the balance vehicle. Therefore, we propose a balance vehicle anti-tipping stabilizing support structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a self-balancing scooter anti-rollover stabilizing support structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-balancing scooter anti-rollover stabilizing support structure includes a connecting frame. A rear frame is fixedly connected to one side of the connecting frame. A rear wheel is installed on the inner wall of the rear frame. Two fixed seats are fixedly installed on the outer surface of the rear frame. Each of the two fixed seats has a support plate inside. Anti-rollover auxiliary wheels are installed on the side of the two support plates that are far apart from each other. Bearing rings are fixedly embedded on the outer surface of each of the two fixed seats. Rotating shafts are fixedly connected to the inner rings of the two bearing rings. The side of the two rotating shafts that are close to each other is fixedly connected to the side of the two support plates that are far apart from each other.

[0007] In a further embodiment, threaded holes are provided on the outer surfaces of both fixing seats, fixing screws are provided on one side of each of the two threaded holes, threaded grooves are provided on the opposite sides of the two support plates, and the outer surfaces of the two fixing screws are respectively adapted to the inner walls of the two threaded grooves.

[0008] In a further embodiment, the outer surfaces of one end of both rotating shafts are threaded, and a locking nut is threadedly connected to the outer surfaces of one end of both rotating shafts.

[0009] In a further embodiment, one end of the connecting frame is fixedly connected to the front frame, and the front wheel is mounted on the inner wall of the front frame.

[0010] In a further embodiment, a support rod is fixedly installed at the top of the rear frame, and a support pad is fixedly connected to the top of the support rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features an anti-rollover auxiliary wheel that unfolds downwards inside the fixed base, allowing it to contact the ground. A combination of fixing screws, threaded holes, and threaded grooves ensures stable fixation, providing continuous additional support for children while riding and reducing the risk of rollover. It is suitable for children whose balance is still developing. When the anti-rollover assist is not needed, loosening the locking nut and unscrewing the fixing screw allows the rotating shaft to rotate inside the bearing ring, causing the support plate to flip the anti-rollover auxiliary wheel to the upper right and retract. This enables and deactivates the anti-rollover function, meeting the riding needs of children at different stages while avoiding the space-consuming problem of the anti-rollover structure when not in use, thus improving the flexibility of children's riding.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4In this utility model, a self-balancing scooter anti-rollover stabilizing support structure includes a connecting frame 1. A rear frame 2 is fixedly connected to one side of the connecting frame 1. A rear wheel 5 is installed on the inner wall of the rear frame 2. Two fixed seats 6 are fixedly installed on the outer surface of the rear frame 2. Each of the two fixed seats 6 has a support plate 7 inside. Anti-rollover auxiliary wheels 11 are installed on the side of the two support plates 7 that are far apart from each other. Bearing rings 8 are fixedly embedded on the outer surface of the two fixed seats 6. Rotating shafts 9 are fixedly connected to the inner rings of the two bearing rings 8. The side of the two rotating shafts 9 that are close to each other is fixedly connected to the side of the two support plates 7 that are far apart from each other. The connecting frame 1 can connect the front frame 3 and the rear frame 2 to form the main frame of the self-balancing scooter. The rear frame 2 can be equipped with the rear wheel 5. The two fixed seats 6 can be used to install anti-rollover components. The anti-rollover auxiliary wheels 11 on the side of the support plates 7 can provide support when the self-balancing scooter tilts.

[0022] In a further embodiment, threaded holes 13 are provided on the outer surfaces of both fixed seats 6, and fixing screws 12 are provided on one side of each of the two threaded holes 13. Threaded grooves 14 are provided on the opposite sides of the two support plates 7. The outer surfaces of the two fixing screws 12 are adapted to the inner walls of the two threaded grooves 14. Threads are provided on the outer surfaces of one end of each of the two rotating shafts 9, and locking nuts 10 are threaded onto the outer surfaces of one end of each of the two rotating shafts 9. Through the threaded holes 13 and fixing screws 12 at the fixed seats 6, and their cooperation with the threaded grooves 14, the support plates 7 can be fixed, ensuring the stability of the anti-rollover auxiliary wheel 11 when supported. By setting the locking nuts 10, the support plates 7 can be adjusted and fixed when the anti-rollover auxiliary wheel 11 needs to be retracted, preventing it from unfolding after retraction.

[0023] In a further embodiment, a front frame 3 is fixedly connected to one end of the connecting frame 1. A front wheel 4 is installed on the inner wall of the front frame 3. A support rod 15 is fixedly installed on the top of the rear frame 2. A support seat 16 is fixedly connected to the top of the support rod 15. The front wheel 4 can be installed on the front frame 3, and in cooperation with the rear frame 2 and the rear wheel 5, the balance bike can move. The support rod 15 and the support seat 16 can provide a support point for the rider's buttocks.

[0024] The working principle of this utility model is as follows: When the child balance bike is in normal riding mode, the support plate 7 makes the anti-rollover auxiliary wheels 11 contact the ground, which can provide additional support for the balance bike. Then, the fixing screw 12 passes through the threaded hole 13 on the fixing seat 6 and is screwed into the threaded groove 14 of the support plate 7 to fix the support plate 7 and prevent it from rotating accidentally. Then, the two anti-rollover auxiliary wheels 11 prevent the bike from tipping over. When the child is proficient in balancing and no longer needs the anti-rollover function, the locking nut 10 and the fixing screw 12 can be loosened and the rotating shaft 9 can be rotated from inside the bearing ring 8. This allows the support plate 7 and the anti-rollover auxiliary wheels 11 to be flipped and adjusted to the upper right, so that the anti-rollover auxiliary wheels 11 are in a retracted state and do not contact the ground. Then, the locking nut 10 and the rotating shaft 9 are used to lock and fix the bike, which does not affect the child's normal riding.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
