AI Technical Summary
When existing scooters encounter uneven road conditions, they are prone to shock, resulting in a reduced driving experience and limited effects of existing shock absorption measures.
A scooter frame structure is designed, divided into a front frame and a rear frame. A rotating connection is formed between the front frame and the rear frame, and at least one shock absorber is installed between the two. The front end of the shock absorber is hinged with the front frame, and the rear end is hinged with the rear frame, and is arranged obliquely above the first shaft.
By separating the front and rear frames and installing shock absorbers, the wheels can be more balancedly absorbed, reducing the vibration sense felt by riders, significantly improving the shock absorption effect, and improving the scooter's user experience.

[0012] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.
[0014] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0015] The embodiment of the present application is a scooter frame structure, and its specific structure is as follows Figure 1-4 shown.
[0016] like Figure 1 As shown, the frame structure includes a front frame 10 and a rear frame 20. The front head tube 11 of the front frame 10 is connected to the front fork 90 of the scooter, and the rear fork 28 of the rear frame 20 is connected to the rear wheel 80 of the scooter. The front of the rear frame 20 is rotatably connected to the rear of the front frame 10 via a first shaft 31. Specifically, the first shaft 31 is a locking shaft, which has strong stability, long service life and is not prone to abnormal noise. The axial direction of the first shaft 31 is perpendicular to the forward direction A of the scooter. Figures 1 to 4 In the figure, the forward direction A of the scooter is the front, and the reverse direction is the rear.
[0017] like Figure 1 As shown, a shock absorber 50 is further connected between the front frame 10 and the rear frame 20, the front end of the shock absorber 50 can be hinged to the lower part of the front frame 10 through a locking shaft, the rear end of the shock absorber 50 is hinged to the rear frame 20, and the shock absorber 50 is arranged obliquely above the first shaft 31. When the front wheel 91 or the rear wheel 80 bounces, the front frame 10 and the rear frame 20 rotate relative to each other, and the shock absorber 50 can absorb and reduce the vibration generated, thereby playing a shock absorbing role.
[0018] In some embodiments, Figure 1As shown, the wire harness 60 connected to the rear wheel 80 passes through the front frame 10 and the rear frame 20. The wire harness 60 can be a wire harness for transmitting electric energy and data, or a brake wire harness for transmitting braking force. The wire harness 60 is routed through the front frame 10 and the rear frame 20, which can improve the protection of the wire harness 60.
[0019] In some embodiments, Figure 1 and Figure 2 As shown, the battery 41 of the scooter is placed in the middle of the rear frame 20, and the rear frame 20 is provided with pedals 21 on both sides of the battery 41. Figure 1 As shown, the controller 42 of the scooter is disposed in the front frame 10. The battery 41 and the controller 42 are both built into the frame, thereby improving the protection of the battery 41 and the controller 42. Figure 1 As shown, a fender 29 is provided at the rear of the rear frame 20 , and the fender 29 covers the rear wheel 80 . In addition, a tail light and a turn signal light (not shown) may be integrated at the rear of the fender 29 .
[0020] In some embodiments, Figure 1 and Figure 2 As shown, the front part of the rear frame 20 is provided with a second shaft 32 parallel to the first shaft 31, and the rear end of the shock absorber 50 is hinged to the rear frame 20 through the second shaft 32. The second shaft 32 is also a locking shaft.
[0021] In some embodiments, Figure 3 and Figure 4 As shown, a seat support rod 70 is provided on the rear frame 20, the bottom of the seat support rod 70 is hinged to the rear frame 20 through the second shaft 32, and the top of the seat support rod 70 is a seat cushion 71. The seat support rod 70 is a telescopic rod with adjustable length, which is used to provide different riding heights. Figure 3 and Figure 4 As shown, the rear frame 20 is provided with a guide seat 22 behind the second shaft 32, and the lower part of the seat support rod 70 is provided with a support foot 72. Figure 3 As shown, the seat support rod 70 is in a folded state, and the rider can stand on the rear frame 20. Figure 4 As shown, the seat support rod 70 rotates to the sitting position, at which time the support foot 72 is located behind the second shaft 32 and the support foot 72 is fixedly engaged with the guide buckle seat 22 to prevent the seat support rod 70 from loosening. Specifically, the support foot 72 has a safety buckle or a safety pin, and when the seat support rod 70 rotates to the sitting position, the safety buckle or the safety pin is inserted into the guide buckle seat 22 to form a clamping fixation.
[0022] In some embodiments, Figure 4As shown, the vertical tube 92 of the front fork 90 penetrates the front head tube 11 of the front frame 10, and the head tube 11 and the vertical tube 92 of the front fork 90 are rotatably connected through the bearing bowl assembly 12, thereby optimizing the steering and directional control function and improving the safety performance. Figure 4 As shown, a shock absorber 93 is also provided in the front fork 90. In other embodiments, a shock absorber (not shown) may be further provided between the rear frame 20 and the rear wheel 80 to enhance the overall shock absorption effect of the scooter.
[0023] The technical solution of the embodiment divides the frame into a front frame 10 and a rear frame 20, and a hinge is formed between the front frame 10 and the rear frame 20 and a shock absorber 50 is connected therebetween. When the front wheel 91 or the rear wheel 80 bounces, the generated bounce will be absorbed by the shock absorber 50, and the vibration felt by the rider standing on the frame is reduced, the shock absorption effect is improved, and the use experience of the scooter is enhanced.
