Description

Technical Field

[0001] This utility model relates to the field of self-balancing scooter technology, specifically to self-balancing scooters. Background Technology

[0002] As a tool for children's early exercise and entertainment, balance bikes are characterized by their lack of pedals and transmission system. By pushing off the ground with their feet, children can develop balance and coordination. Traditional balance bike frames are made by welding metal tubing or sheet metal into a non-removable monolithic structure. While this design ensures structural strength in mass production, the monolithic frame is bulky and irregularly shaped. Long-distance transportation requires dedicated racks or containers, resulting in high logistics costs. Damage to the welded structure necessitates the entire bike being returned to the factory for repair, and partial damage requires replacing the entire frame, increasing the average maintenance cost for users. Furthermore, they cannot be used in the trunk of a car or in public transportation storage spaces, limiting the product's versatility.

[0003] Therefore, designing a self-balancing scooter to overcome the aforementioned technical shortcomings and improve its overall practicality is of paramount importance. Utility Model Content

[0004] The purpose of this invention is to provide a self-balancing scooter to solve the problems mentioned in the background section.

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

[0006] A self-balancing scooter includes a front wheel frame assembly and a rear wheel frame assembly on one side of the front wheel frame assembly. The front wheel frame assembly and the rear wheel frame assembly are connected by a number of horizontal tubes. Each horizontal tube has symmetrical positioning holes at both ends. A T-shaped limiting tube is provided inside the positioning hole. A threaded groove is provided on the inner side wall of one end of the T-shaped limiting tube, and a screw is connected to the threaded groove.

[0007] The front wheel frame assembly includes symmetrically arranged handlebars, a first frame, and a front wheel. The rear wheel frame assembly includes a seat assembly, a second frame, and a rear wheel. The first frame and the second frame are each provided with a plurality of receiving cavities, and the inner sidewalls of the receiving cavities are symmetrically provided with assembly holes.

[0008] As a preferred embodiment of this utility model, the position of the assembly hole is opposite to the position of the positioning hole, and the T-shaped limiting tube is provided through the assembly hole and the positioning hole.

[0009] As a preferred embodiment of this utility model, the transverse cross-sectional area of ​​one end of the T-shaped limiting tube is larger than the transverse cross-sectional area of ​​the assembly hole, that is, one end of the T-shaped limiting tube completely covers the assembly hole.

[0010] As a preferred embodiment of this utility model, there are two horizontal tubes, which are arranged in parallel and spaced apart between the front wheel frame assembly and the rear wheel frame assembly. The two ends of the horizontal tubes are adapted to the receiving cavity and are inserted into each other.

[0011] As a preferred embodiment of this utility model, the seat assembly includes a height-adjustable seat post and a hinged saddle, and is fixed in position to the second frame by a locking fastener.

[0012] As a preferred embodiment of this utility model, the horizontal tube is made of aluminum alloy and is hollow.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a self-balancing scooter is designed with a modular structure, utilizing horizontal tubes, positioning holes, T-shaped limiting tubes, threaded grooves, screws, a receiving cavity, and assembly. The scooter features a split-type structure, with the front wheel frame assembly and the rear wheel frame assembly connected by double parallel aluminum alloy horizontal tubes. After the two ends of the horizontal tubes are inserted into the corresponding receiving cavities of the frame, they are aligned through positioning holes and assembly holes, and then pass through T-shaped limiting tubes to form mechanical stops. A rigid connection is achieved by locking with screws. This design allows for quick disassembly into independent modules, making it easy to store in small spaces such as the trunk of a family car. If a single horizontal tube or frame is damaged, the corresponding module can be replaced individually, significantly reducing maintenance costs. This design solves the problems of bulky and irregularly shaped integral frames, which require dedicated racks or containers for long-distance transportation, resulting in high logistics costs. Furthermore, partial damage requires replacing the entire frame, increasing the average maintenance cost for users. Attached Figure Description

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A self-balancing scooter includes a front wheel frame assembly 1, a rear wheel frame assembly 2 on one side of the front wheel frame assembly 1, and the front wheel frame assembly 1 and the rear wheel frame assembly 2 are connected by several horizontal tubes 3. Each horizontal tube 3 has symmetrically arranged positioning holes 301 at both ends. A T-shaped limiting tube 302 is provided inside the positioning hole 301. A threaded groove 303 is provided on the inner sidewall of one end of the T-shaped limiting tube 302, and a screw 304 is connected to the threaded groove 303. The front wheel frame assembly 1 includes symmetrically arranged handlebars 101, a first frame 102, and a front wheel 103. The rear wheel frame assembly 2 includes a seat assembly 201, a second frame 202, and a rear wheel 203. The first frame 102 and the second frame 202 each have several receiving cavities 4. The inner sidewalls of the receiving cavities 4 are aligned with the front wheel frame assembly 101 and the rear wheel frame assembly 203. The vehicle is equipped with an assembly hole 401. The front wheel frame assembly 1 and the rear wheel frame assembly 2 are connected by two parallel horizontal tubes 3. The two ends of the horizontal tubes 3 are inserted into the receiving cavities 4 of the first frame 102 and the second frame 202 to ensure that the positioning hole 301 of the horizontal tube 3 is precisely aligned with the assembly hole 401 of the receiving cavity 4. The T-shaped limiting tube 302 passes through the assembly hole 401 and the positioning hole 301, and uses its end lateral area to cover the assembly hole 401 to form a mechanical stop. The screw 304 is screwed into the threaded groove 303 to lock, thus completing the rigid connection of the frame. The hollow structure of the horizontal tube reduces the overall weight. When disassembling, the front and rear frame assemblies and the horizontal tubes 3 are separated, reducing the volume to fit the trunk of a family car. When there is partial damage, only the corresponding module, such as a single horizontal tube or the frame, needs to be replaced, thus reducing maintenance costs.

[0025] The assembly hole 401 is positioned opposite the positioning hole 301, and the T-shaped limiting tube 302 passes through both the assembly hole 401 and the positioning hole 301. The alignment of the assembly hole 401 and the positioning hole 301 ensures the coaxiality of the T-shaped limiting tube 302 after it passes through, preventing stress concentration caused by connection misalignment and extending the frame's lifespan. The transverse cross-sectional area of ​​one end of the T-shaped limiting tube 302 is larger than that of the assembly hole 401, meaning one end of the T-shaped limiting tube 302 completely covers the assembly hole 401. The larger transverse area at the end of the T-shaped limiting tube 302 forms a mechanical stop, preventing screw 3 from... When loose, the cross tube 3 comes out. There are two cross tubes 3, which are arranged in parallel and spaced between the front wheel frame assembly 1 and the rear wheel frame assembly 2. The two ends of the cross tube 3 are adapted to the receiving cavity 4 and are inserted into it. The parallel double cross tubes 3 achieve distributed force distribution by inserting into the receiving cavity 4, which enhances the frame's torsional resistance. The seat assembly 201 includes a height-adjustable seat post and a hinged saddle, and is fixed to the second frame 202 by locking fasteners to improve riding comfort and ergonomic fit. The cross tube 3 is made of aluminum alloy and is hollow. The aluminum alloy material combined with the hollow design achieves lightweighting.

[0026] The working process of this utility model is as follows: When using the self-balancing scooter, the front wheel frame assembly 1 and the rear wheel frame assembly 2 are first connected by two parallel horizontal tubes 3. The two ends of the horizontal tubes 3 are inserted into the receiving cavities 4 of the first frame 102 and the second frame 202, ensuring that the positioning hole 301 of the horizontal tube 3 is precisely aligned with the assembly hole 401 of the receiving cavity 4. The T-shaped limiting tube 302 is passed through the assembly hole 401 and the positioning hole 301, and its end lateral area covers the assembly hole 401 to form a mechanical stop. The screw 304 is screwed into the threaded groove 303 to lock it, thus completing the rigid connection of the frame. The hollow structure of the horizontal tube 3 reduces the overall weight. When disassembling, the front and rear frame assemblies and the horizontal tubes 3 are separated, reducing the volume to fit the trunk of a family car. When there is partial damage, only the corresponding module, such as a single horizontal tube or the frame, is replaced, reducing maintenance costs.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
