Description

Technical Field

[0001] This utility model relates to the field of scooters, and in particular to a scooter frame and a scooter. Background Technology

[0002] Scooters are a common short-distance transportation tool and recreational sports equipment, typically composed of core components such as a frame, wheels, handlebars, pedals, and braking system. With their lightweight and flexible characteristics, they are widely used for short-distance urban commuting, school travel, and daily entertainment. The scooter frame is the core load-bearing and connecting structure of the entire scooter, generally made of materials such as aluminum alloy, steel, or high-strength plastic. Its main function is to secure the pedals, handlebar stem, wheel supports, and braking components. The rationality of its design directly determines the scooter's load-bearing capacity, riding stability, and lifespan, forming the basic framework for ensuring the scooter's safe use and functionality.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN209972667U, a scooter frame is disclosed, which is quickly installed through multiple structures and buckle cooperation. However, in practical applications, it has been found that due to the low center of gravity of the scooter and the high handlebars, the human body will be greatly affected by inertia when accelerating or braking suddenly, resulting in backward or forward tilting. In addition, the speed of the existing electric scooters is relatively fast, and the human body sometimes has difficulty reacting quickly. Utility Model Content

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figures 1-8 As shown, a scooter frame includes a support mechanism 1 for support, an adjustment mechanism 2 that adapts to inertia by swinging, and a follower mechanism 3 for adjusting the speed in conjunction with the adjustment mechanism 2. The adjustment mechanism 2 is slidably mounted on the support mechanism 1, and the follower mechanism 3 is disposed inside the support mechanism 1 and connected to the bottom of the adjustment mechanism 2.

[0035] The support mechanism 1 includes a main frame 11 with grooves for installation. The adjustment mechanism 2 includes a pedal 21 with swing frames 24 on both sides of the bottom of the pedal 21. The bottom of the swing frame 24 is fitted with a support frame 25 through a sliding component. The support frame 25 is fixed to the bottom of the groove of the main frame 11. The swing frame 24 has an arc-shaped structure, and the support frame 25 has an arc-shaped groove. The pedal 21 slides with the support frame 25 and the main frame 11 through the swing frame 24. The upper surface of the main frame 11 has an adjustment groove 23 formed at the position of the pedal 21. The main frame 11 has a hollow structure, and a battery (not shown) is installed in the space except for the main components.

[0036] The follower mechanism 3 includes a double-headed hydraulic cylinder 31. An upper follower frame 32 is installed at the center of the bottom surface of the pedal 21. The upper follower frame 32 is connected to the center of the double-headed hydraulic cylinder 31. The double-headed hydraulic cylinder 31 is installed horizontally on the lower side of the pedal 21. The two piston rods of the double-headed hydraulic cylinder 31 correspond to the two ends of the pedal 21 respectively. An oil pipe 34 is installed on the side of the double-headed hydraulic cylinder 31. A solenoid valve 33 is installed at the center of the oil pipe 34. The two piston rods of the double-headed hydraulic cylinder 31 are respectively equipped with connecting frames 36. The connecting frames 36 are connected to the inner bottom surface of the main frame 11 through the lower follower frame 35.

[0037] In this embodiment, the sliding component includes a swing limiting block 241 and a swing limiting groove 251. Two swing limiting blocks 241 are symmetrically arranged on the arc surface of each swing frame 24. The arc groove end face of the support frame 25 is formed with a swing limiting groove 251 that matches the swing limiting block 241. The limiting block 241 and the limiting groove 251 are used to limit the flipping of the pedal 21.

[0038] In this embodiment, one end of the upper follower frame 32 is fixed to the pedal 21, and the other end of the upper follower frame 32 is rotatably connected to the double-headed hydraulic cylinder 31 through a pin, providing a gap and fixation during flipping, thereby preventing jamming.

[0039] In this embodiment, steps are provided on both sides of the main frame 11 corresponding to the adjustment groove 23 to further provide limiting.

[0040] In this embodiment, an anti-slip block 22 is provided on the top of the pedal 21. The anti-slip block 22 is made of hard rubber and is connected to the pedal 21 by screws to improve the frictional fit between the shoe sole and the pedal 21.

[0041] In this embodiment, a front connecting frame 12 is welded to the front end of the main frame 11, a front shock absorber 13 is connected to the front end of the front connecting frame 12, and a rear shock absorber 14 is connected to the rear end of the main frame 11.

[0042] In this embodiment, the anti-slip block 22 has a V-shaped structure.

[0043] In this embodiment, the main frame 11 and the front connecting frame 12 are made of aluminum alloy.

[0044] In this embodiment, the width of the main frame 11 is greater than the width of the pedal 21, and the portion of the main frame 11 that is wider than the pedal 21 is a smooth surface.

[0045] A scooter also includes a main pole 4, a handlebar 5, and wheels 6. The main pole 4 is rotatably connected to a front shock absorber 13, and the bottom of the rear shock absorber frame 14 is connected to the wheels 6 via a wheel frame. The handlebar 5 is installed on the top of the main pole 4, and the rear shock absorber frame 14 is connected to a wheel mechanism and a rear wheel at its rear end.

[0046] Working principle: When a person stands on pedal 21, the anti-slip block 22 increases friction. When the turbine is started by controlling the switch on the handrail 5, the speed changes rapidly. At this time, the solenoid valve 33 controlled by the electric switch is fully opened. At the moment of start-up, the inertia combined with the weight of the human body causes pedal 21 to drive the swing frame 24 to slide backward on the support frame 25. When pedal 21 slides backward, it drives the double-headed cylinder 31 to squeeze the piston rod at the rear end. Since the rear end of the piston rod is connected to the main frame 11 through the lower follower frame 35, the double-headed cylinder 31 provides damping. After pedal 21 slides backward, it will generate an inclined angle, thereby providing forward support for the feet and improving the stability during start-up.

[0047] When sudden braking occurs, the vehicle is braked due to the inertia of the human body, and the human body is driven by inertia to move the pedal 21 forward. After the pedal 21 moves forward, it tilts upward, providing a front support and reducing the probability of tipping forward.

[0048] The motors and their associated control systems, power supply modules, circuits, and pipelines mentioned in this article can be provided by the manufacturer. Apart from that, all electronic components and control modules involved in this utility model are existing technologies that can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by this utility model does not involve any improvement to the structure and usage of electronic components.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
