Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, specifically to a slant tube assembly for an electric scooter. Background Technology

[0002] Traditional electric scooter slant tube assemblies often use bolt-fastened connections. Over long-term use, vibrations from vehicle movement can easily cause relative displacement between the tubes, affecting the stability of the scooter. Existing anti-displacement solutions mainly rely on adding welding points or auxiliary fasteners; however, this not only increases the weight of the frame but also makes maintenance and disassembly more difficult.

[0003] While some of the improved designs enable quick assembly through slot positioning, the contact surfaces between the pipes lack adaptive adjustment capabilities, resulting in fretting wear issues under bumpy road conditions.

[0004] In addition, conventional inclined tube assemblies have a single positioning reference, requiring repeated adjustments to the alignment angle during installation, resulting in low operational efficiency. Therefore, an inclined tube assembly for electric scooters is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the above defects and provide a slant tube assembly for an electric scooter. It innovates and optimizes the connection structure and positioning method, and solves the technical problems of existing technology, such as the relative displacement caused by vibration during long-term use affecting the stability of the vehicle body, the increase in frame weight and maintenance and disassembly difficulty due to anti-displacement measures, the lack of self-adjustment function between tubes leading to micro-motion wear, and the low efficiency of installation operation due to the single positioning reference.

[0006] The objective of this utility model is achieved through the following means:

[0007] An electric scooter's slant tube assembly includes a frame and a slant tube. The slant tube is installed at one end of the frame. Conical guide blocks are welded and fixed to the upper and lower sides of the slant tube near the frame end. Side cavities are formed on the front and rear sides of the interior of the conical guide blocks. A return spring and a limiting block are installed sequentially from the inside to the outside of the side cavities. Limiting shells are welded and fixed to the upper and lower sides of the frame near the conical guide blocks. Dovetail grooves are formed inside the limiting shells, and the conical guide blocks are adapted to the dovetail grooves. Side slots are formed on the front and rear sides of the dovetail grooves, and the side slots are adapted to the limiting blocks. A limiting boss is welded and fixed to the interior of the slant tube near the frame end.

[0008] Furthermore, a first reinforcing rib, evenly distributed along a ring, is welded and fixed to the inside of the inclined tube on the side opposite to the limiting boss.

[0009] Furthermore, inside the inclined tube, between the first reinforcing rib and the limiting boss, there is a support rib that is welded and fixed along the ring, which increases the strength of the connection part of the inclined tube.

[0010] Furthermore, a telescopic rod is installed inside the reset spring, and the two ends of the telescopic rod are fixedly connected to the side cavity and the limiting block, respectively. The telescopic rod makes the movement stroke of the limiting block stable.

[0011] Furthermore, a toggle block is provided on the outer side of the limiting plug, and the toggle block is welded and fixed to the limiting plug, making it easy to move the limiting plug.

[0012] Furthermore, a second reinforcing rib is provided at the lower end of the inclined tube near the frame, and the second reinforcing rib is welded and fixed to the inclined tube. The second reinforcing rib is used to strengthen the strength of the inclined tube.

[0013] The beneficial effects of this utility model are:

[0014] This utility model, through the cooperation of a tapered guide block and a dovetail groove, makes the assembly and connection of the slant tube to the frame convenient and quick, so as to facilitate rapid positioning and alignment. After the tapered guide block is inserted into the dovetail groove, the limit plug is pushed out by the return spring and combined with the side groove to ensure the stability of the connection between the slant tube and the frame and prevent relative displacement. When the slant tube is inserted into the frame to a certain depth, the limit boss abuts against the end of the frame to prevent deformation failure caused by excessive insertion of the slant tube. In summary, this invention solves the problems mentioned in the background art. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, refer to Figures 1-4 The present invention relates to a slant tube assembly for an electric scooter, comprising a frame 1 and a slant tube 2. The slant tube 2 is installed at one end of the frame 1. Conical guide blocks 7 are welded and fixed on both the upper and lower sides of the slant tube 2 near the end of the frame 1. Side cavities 11 are opened on both the front and rear sides of the interior of the conical guide blocks 7. A return spring 13 and a limiting block 14 are installed sequentially from the inside to the outside of the side cavities 11. Limiting shells 8 are welded and fixed on both the upper and lower sides of the exterior of the frame 1 near the conical guide blocks 7. A dovetail groove 9 is opened inside the limiting shell 8, and the conical guide blocks 7 are adapted to the dovetail groove 9. Side grooves 10 are opened on both the front and rear sides of the interior of the dovetail groove 9, and the side grooves 10 are adapted to the limiting block 14. A limiting boss 5 is welded and fixed on the interior of the slant tube 2 near the end of the frame 1.

[0022] like Figure 1 and Figure 2 As shown, the inside of the inclined tube 2, away from the limiting boss 5, is welded and fixed with a first reinforcing rib 3 that is evenly distributed along the ring.

[0023] like Figure 1 and Figure 2 As shown, inside the inclined tube 2, between the first reinforcing rib 3 and the limiting boss 5, there is a support rib 4 that is evenly distributed along the ring. The support rib 4 improves the strength of the connection part of the inclined tube 2.

[0024] like Figure 3 and Figure 4 As shown, a telescopic rod 12 is installed inside the return spring 13. The two ends of the telescopic rod 12 are fixedly connected to the side cavity 11 and the limiting block 14, respectively. The telescopic rod 12 makes the movement stroke of the limiting block 14 stable.

[0025] like Figure 3 and Figure 4 As shown, a toggle block 15 is provided on the outer side of the limiting plug 14, and the toggle block 15 is welded and fixed to the limiting plug 14. The toggle block 15 makes it easy to toggle the limiting plug 14.

[0026] like Figure 1 and Figure 2 As shown, a second reinforcing rib 6 is provided on the lower end of the inclined tube 2 near the side of the frame 1, and the second reinforcing rib 6 is welded and fixed to the inclined tube 2. The second reinforcing rib 6 is used to strengthen the strength of the inclined tube 2.

[0027] The installation process of the slant tube assembly of an electric scooter in this embodiment is as follows: The lower end of the slant tube 2 is inserted into the upper end of the frame 1. The limiting plug 14 is pinched into the side cavity 11 and the tapered guide block 7 is combined with the dovetail groove 9 of the limiting shell 8. The tapered guide block 7 is completely combined with the dovetail groove 9. The return spring 13 pushes the limiting plug 14 outward and inserts it into the side groove 10. At the same time, the limiting boss 5 inside the slant tube 2 contacts the end of the frame 1 to limit the insertion stroke of the slant tube 2. When it is necessary to disassemble the slant tube 2, the lever 15 is pulled to make the limiting plug 14 retract into the side cavity 11. Then the slant tube 2 is pulled away from the frame 1 to complete the separation.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
