Description

Technical Field

[0001] This utility model relates to scooters, and more particularly to a scooter frame reinforcement structure. Background Technology

[0002] To improve the structural strength of the scooter frame, CN222117010U utilizes connecting blocks to increase welding points at the second and fourth connecting parts, thereby enhancing the stability of the ramp and base plate after welding. However, since the connecting blocks only reinforce the connection between two components, their overall structural reinforcement effect is somewhat insufficient. Therefore, the aforementioned patent application has room for improvement. Utility Model Content

[0003] The main purpose of this utility model is to provide a frame reinforcement structure for a scooter that can improve the overall structural strength.

[0004] To achieve the aforementioned main objectives, the frame reinforcement structure provided by this utility model includes a footrest, a front support frame, a lower bracket, and two opposing side reinforcement plates. The front support frame has a vertical support tube and a slanted tube, with the top end of the slanted tube connected to the vertical support tube; the lower bracket is located between the front end of the footrest and the bottom end of the slanted tube; the side reinforcement plates are located at the connection points of the footrest, the slanted tube, and the lower bracket.

[0005] As can be seen from the above, the frame reinforcement structure of this utility model utilizes the reinforcement plates to reinforce the connection between the pedal, the inclined tube and the lower bracket, thereby achieving the purpose of improving the overall structural strength.

[0006] Preferably, a reinforcing plate is provided at the connection between the pedal and the lower bracket to further increase the connection strength between the pedal and the lower bracket.

[0007] Preferably, the lower reinforcing plate has an upper reinforcing portion, a lower reinforcing portion, and an oblique extension connecting the upper reinforcing portion and the lower reinforcing portion. The upper reinforcing portion connects to the bottom surface of the front end of the pedal, while the lower reinforcing portion connects to the bottom surface of the rear end of the lower bracket. The lower reinforcing plate further increases the connection strength between the pedal and the lower bracket.

[0008] Preferably, the pedal has a rear end and two side grooves extending through both ends, and the pedal also has two welding holes located at the rear end and communicating with the side grooves. Two rear forks are inserted into one of the side grooves from the rear end of the pedal and correspond to one of the welding holes. Welding reinforcement is performed through these welding holes, thereby increasing the connection strength between the pedal and the rear forks.

[0009] Preferably, the lower bracket also has a front end and a rear end, the front end of the lower bracket being connected to the bottom end of the inclined tube, and the rear end of the lower bracket being connected to the front end of the pedal. The overall structural strength is improved by assembling and welding the pedal, the lower bracket, and the inclined tube together.

[0010] Preferably, the pedal also has two notches, which are located at the front end and communicate with the side grooves. Each side reinforcing piece is inserted from the front end of the pedal into a side groove and positioned within a notch.

[0011] Detailed construction, features, assembly, and usage of the scooter frame reinforcement structure provided by this invention will be described in the subsequent detailed description of the embodiments. However, those skilled in the art should understand that these detailed descriptions and the specific embodiments listed for implementing this invention are for illustrative purposes only and are not intended to limit the scope of patent protection of this invention.

[0041] First, it should be noted that throughout this specification, including the embodiments described below and the claims, all directional terms are based on the directions shown in the accompanying drawings. Second, in the embodiments and drawings described below, the same element reference numerals represent the same or similar elements or their structural features.

[0042] Please refer to the following: Figure 1 and Figure 2 As shown, the frame reinforcement structure 10 of this utility model is mainly used in a scooter (not shown in the figure), which includes a footboard 20, a front support frame 30, a lower bracket 40, and two oppositely arranged side reinforcement plates 50.

[0043] The pedal 20 has a front end 21 and a rear end 22. The top surface of the front end 21 has two opposing notches 23, and the top surface and outer surface of the rear end 22 each have a welding hole 24. Furthermore, the pedal 20 also has a central groove 25 penetrating the front end 21 and the rear end 22, and two side grooves 26 penetrating the front end 21 and the rear end 22. The two side grooves 26 are located on the left and right sides of the central groove 25, and the front ends of the two side grooves 26 connect to the two notches 23, while the rear ends of the two side grooves 26 respectively connect to the two welding holes 24. Figure 2As shown, the two rear forks 70 are inserted into the two side slots 26 from the rear end 22 of the pedal 20 and correspond to the two welding holes 24 respectively. Welding reinforcement is carried out through these welding holes 24, thereby increasing the connection strength between the pedal 20 and the two rear forks 70.

[0044] The front support frame 30 has a pole fixing tube 31 and an inclined tube 32. The pole fixing tube 31 is used to fix a driver's pole (not shown). The inclined tube 32 has a top end 33 and a bottom end 34. The top end 33 of the inclined tube 32 is connected to the pole fixing tube 31, and the bottom end 34 of the inclined tube 32 has a bottom groove 35.

[0045] The lower bracket 40 is located between the front end 21 of the pedal 20 and the bottom end 34 of the inclined tube 32. The lower bracket 40 has a front end 41 and a rear end 42. The front end 41 of the lower bracket 40 is accommodated in the bottom groove 35 of the inclined tube 32 and is welded to the bottom end 34 of the inclined tube 32. The rear end 42 of the lower bracket 40 is welded to the front end 21 of the pedal 20. By assembling and welding the pedal 20, the lower bracket 40, and the inclined tube 32 together, the overall structural strength can be effectively improved.

[0046] like Figures 2 to 4 As shown, two side reinforcing plates 50 are inserted into two side grooves 26 from the front end 21 of the pedal 20 and positioned in two notches 23. They are then welded together to the front end 21 of the pedal 20, the bottom end 34 of the inclined tube 32, and the rear end 42 of the lower bracket 40, so that the two side reinforcing plates 50 reinforce the connection between the pedal 20, the inclined tube 32, and the lower bracket 40.

[0047] To further enhance structural strength, this utility model also provides a reinforcing sheet 60, such as... Figure 2 and Figure 5 As shown, the lower reinforcing plate 60 is Z-shaped and has an upper reinforcing part 61, a lower reinforcing part 62, and an oblique extension 63 connecting the upper reinforcing part 61 and the lower reinforcing part 62. The upper reinforcing part 61 is welded to the bottom surface of the front end 21 of the pedal 20, and the lower reinforcing part 62 is welded to the bottom surface of the rear end 42 of the lower bracket 40, so that the lower reinforcing plate 60 increases the connection strength between the pedal 20 and the lower bracket 40.

[0048] As can be seen from the above, the frame reinforcement structure 10 of this utility model, on the one hand, utilizes the mutual assembly and welding of the pedal 20, the lower bracket 40 and the inclined tube 32 to effectively improve the overall structural strength; on the other hand, it strengthens the connection between the pedal 20, the inclined tube 32 and the lower bracket 40 through the two side reinforcement plates 50, and strengthens the connection between the pedal 20 and the lower bracket 40 through the lower reinforcement plate 60, thereby improving the firmness of the three after mutual assembly and welding.
