[0001] This utility model relates to the field of scooter technology, and to an aluminum one-piece tubular scooter frame and scooter. Background Technology
[0002] Electric scooters are based on traditional human-powered skateboards, powered by a built-in battery, primarily a lithium battery pack. Compared to traditional electric bicycles, electric scooters have advantages such as simple structure, small wheels, lightweight and convenient operation, and the ability to save significant social resources, making them popular among the general public.
[0003] However, most scooter frames currently used are made of iron, which is heavy; not only is the structure complex, but the molds and finished products are also expensive, assembly is difficult, and they are easily damaged after a period of use, lacking sufficient strength and requiring long-term maintenance. In addition, existing frames are relatively large, limiting their packing capacity.
[0004] The aforementioned problems have caused significant disruption to user experience, resulted in substantial financial waste for businesses, and lowered user expectations due to the high cost.
[0005] In summary, there is a need to provide a lightweight, aesthetically pleasing, structurally simplified, high-strength, and inexpensive scooter frame to address the aforementioned issues. Summary of the Invention

[0007] The technical solution adopted by this utility model to solve its technical problem is: An aluminum one-piece tubular scooter frame includes a frame tube and a rear fork. The frame tube is a one-piece hollow aluminum tube, bent to form an interconnected vertical and horizontal section. The end of the horizontal section is welded to the rear fork. A piece is missing from the top surface of the horizontal section to form a strip-shaped notch, making the horizontal section a horizontal notched tube. A battery can be detachably placed into the horizontal notched tube through this strip-shaped notch. Reinforcing seats are welded to the bottom and sides of the horizontal section.
[0008] Furthermore, the size of the battery matches the size of the strip-shaped notch, and the top surface of the battery is flush with the top surface of the horizontal notch tube, thus omitting the frame tube cover plate.
[0009] Furthermore, the width of the horizontal notch pipe is 60-80mm and the height is 80-100mm; the strip notch is excavated starting 20-50mm from the end of the horizontal notch pipe, and the cross-section of the strip notch is U-shaped.
[0010] Furthermore, the reinforcing seat includes a U-shaped connecting part and through-shaft parts at both ends of the U-shaped connecting part. The through-shaft parts are located on both sides of the horizontal part and have through channels inside for inserting the pivot of the folding pedal.
[0011] Furthermore, the U-shaped connecting part is welded to the bottom of the frame tube and extends to both sides of the horizontal part; multiple pairs of the through-shaft parts are provided on both sides of the horizontal part; the reinforcing seat is made of die-cast aluminum.
[0012] Furthermore, an internal reinforcing plate is welded and fixed above the bottom surface of the horizontal part along the length direction. The internal reinforcing plate is designed as a plate structure. The internal reinforcing plate is welded obliquely above the bottom surface of the horizontal part, thereby facilitating bottom wiring between the bottom of the internal reinforcing plate and the top of the bottom surface of the horizontal part. The internal reinforcing plate has holes to facilitate wiring through and fixation. The shape of the internal reinforcing plate matches the bottom of the battery. The internal reinforcing plate is made of aluminum profile.
[0013] Furthermore, the frame tube is manufactured using a water-expanding process.
[0014] Furthermore, the rear fork includes an integrally formed left rear fork and a right rear fork, with a tail reinforcement plate welded and fixed between the left and right rear forks. The tail reinforcement plate is made of aluminum sheet metal.
[0015] Furthermore, the frame also includes a head tube, which is welded to the upper end of the upright portion, and the head tube is made of aluminum.

[0026] Reference Figures 1 to 6 As shown, the aluminum tubular scooter frame of this embodiment includes a head tube 1, a frame tube 2, and a rear fork 4 connected in sequence.
[0027] In this embodiment, the head tube 1 is welded to the upper end of the frame tube 2. The head tube 1 is made of aluminum profile.
[0028] In this embodiment, the frame tube 2 is made of aluminum, which achieves the goal of lightweighting compared to the iron frames on the market.
[0029] The frame tube 2 is manufactured using a water-expanding process, resulting in a more aesthetically pleasing appearance compared to frames on the market.
[0030] The frame tube 2 is a one-piece design at the front and rear, eliminating the need for welding and assembly of the slanted tubes and bottom frame found in existing models, thus simplifying the manufacturing process.
[0031] The frame tube 2 is hollow inside and is bent. It includes an interconnected vertical part and a horizontal part. The upper end of the vertical part is welded to the head tube 1, and the tail end of the horizontal part is welded to the rear fork 4.
[0032] The horizontal section is hollow, forming a storage cavity for placing batteries, enabling battery removability and facilitating charging. In this embodiment, the width of the horizontal section is 60-80mm, and the height is 80-100mm.
[0033] Specifically, a section is missing from the top surface of the horizontal section, forming a strip-shaped notch; thus, the horizontal section becomes a horizontally missing cap tube. Figure 1 As shown, the battery can be detachably inserted into the horizontal notch tube through this notch.
[0034] Preferably, the size of the battery matches the size of the strip notch, and the top surface of the battery is flush with the top surface of the horizontal notch tube, eliminating the need for a conventional frame tube cover plate, resulting in a simpler structure.
[0035] In this embodiment, the strip-shaped notch of the horizontal cover pipe is excavated starting from a distance of 20-50mm from the end of the horizontal cover pipe.
[0036] In this embodiment, the strip notch cross-section is set to U-shape.
[0037] Among them, an internal reinforcing plate 6 is provided above the bottom surface of the horizontal cover tube along the length direction, which strengthens the interior of the frame tube 2.
[0038] The internal reinforcing plate 6 is designed as a plate structure and is placed at an angle above the bottom surface of the horizontal cover tube. This allows for easy routing of bottom wiring between the bottom of the internal reinforcing plate 6 and the top surface of the horizontal cover tube. In addition, the internal reinforcing plate 6 also has holes to facilitate the routing and fixing of wiring for the rear electrical components.
[0039] The plate-like structure of the internal reinforcing plate 6 matches the bottom of the battery.
[0040] In this embodiment, the internal reinforcing plate 6 is made of aluminum profile and is welded and fixed to the bottom surface of the horizontal capped tube.
[0041] Among them, a reinforcing seat 3 is provided below the horizontal capped tube. The reinforcing seat 3 includes a U-shaped connecting part and a through-shaft part at both ends of the U-shaped connecting part.
[0042] The U-shaped connector is set perpendicular to the length direction of the horizontal capless tube. The U-shaped connector is fixed below the bottom of the horizontal capless tube and extends to both sides of the horizontal capless tube.
[0043] In this way, U-shaped connecting parts are provided at the bottom and on both sides of the horizontal cover tube, and an internal reinforcing plate 6 is provided at the top of the bottom of the horizontal cover tube. Therefore, it can be supported from both the inner and outer sides of the frame tube 2, thereby improving the structural stability and structural strength of the frame tube 2.
[0044] Furthermore, the axle section is provided with a through channel in the front and back directions for inserting the pivot to rotate the folding pedal.
[0045] Preferably, the through-shaft portion is designed as a strip-shaped structure.
[0046] Preferably, multiple pairs of through-shaft sections are provided on the left and right sides of the horizontal capped tube.
[0047] Preferably, the reinforcing seat 3 in this embodiment is made of aluminum die casting process, and the reinforcing seat 3 is welded and fixed to the bottom and both sides of the horizontal cap tube.
[0048] The front end of the horizontal cap-less tube is equipped with a battery front fixing plate 5, which is welded to the upper part of the front end of the horizontal cap-less tube. The battery front fixing plate 5 has three holes, including a central positioning hole and two fixing holes on both sides. The battery front fixing plate is a plastic part used for snap-fit connection with the front end of the battery. The two sides of the front end of the battery front fixing plate are inserted into the fixing holes by screws, and the front end of the battery front fixing plate has a guide boss in the middle, which matches the positioning hole.
[0049] Preferably, in this embodiment, the battery front lock plate 5 is made of aluminum sheet metal.
[0050] The rear fork 4 is connected to the end of the horizontal cap tube. The rear fork 4 includes a left rear fork and a right rear fork, which are integrally formed. In this embodiment, the left and right rear forks are fixed to the end of the horizontal cap tube by welding. In this embodiment, the left and right rear forks are made of aluminum profiles.
[0051] Preferably, a tail reinforcement plate 7 is provided between the left and right rear forks. In this embodiment, the tail reinforcement plate 7 is made of aluminum sheet metal. The tail reinforcement plate 7 is welded between the left and right rear forks to prevent the rear forks 4 from breaking and to provide reinforcement.
[0052] The method for manufacturing the integrated frame tube 2 in this embodiment includes: The round tube profile is formed into two sections with different diameters through a tube shrinking process (not a necessary process). The two sections with different diameters are bent by bending to form a vertical part and a horizontal part. The vertical part has a smaller diameter, while the horizontal part has a relatively wider diameter. The water-expanded tube process shapes the entire frame tube 2, resulting in a more aesthetically pleasing design. Machining: The above-mentioned strip-shaped notches, holes, grooves, etc. are formed on the frame tube 2.
[0053] The above description is merely a preferred embodiment of the present utility model and does not constitute a limitation on the scope of protection of the present utility model.
