[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0019] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A lightweight electric scooter frame includes a footboard 1 and a limiting assembly 3. The footboard 1 is the main load-bearing structure. One end of the footboard 1 is provided with a cylindrical rod 101, which serves as a pivot. A connecting rod 2 is fitted onto the cylindrical rod 101, connecting the footboard 1 to the front of the scooter. A semi-circular disk 102 is provided on one side of the footboard 1, with four evenly spaced limiting holes 103. The semi-circular disk 102 and the limiting holes 103 serve as an angle positioning disk. The limiting assembly 3 includes a limiting rod 301. A groove 201 is provided on one side of the connecting rod 2, and a sliding hole 202 is provided on one side of the groove 201. The limiting rod 301 fits into the sliding hole 202. A first baffle 302 is provided outside the limiting rod 301, located inside the groove 201. The first baffle 302, inside the groove 201, cooperates with the sliding hole 202 to restrict the limiting rod. 301 can only move along the axis to prevent it from tilting or falling off, ensuring smooth and precise locking action and improving the reliability of the mechanism. A second spring 304 is sleeved on the outside of the limit rod 301. One end of the second spring 304 is connected to the first baffle 302, and the other end is connected to the inner wall of the sliding hole 202. The second spring 304 provides the elastic force to automatically insert the limit rod 301 into the limit hole 103, realizing automatic rebound locking. A second baffle 303 is provided at one end of the limit rod 301. The second baffle 303 acts as a handle for the limit rod 301 and also limits the limit rod 301 from being excessively pushed out by the spring, so that it will not completely disengage from the sliding hole 202. The second baffle 303 is located on one side of the sliding hole 202. The other end of the limit rod 301 is inserted into the limit hole 103. The limit rod 301 is the core locking pin and is directly inserted into the limit hole 103 to realize mechanical locking.

[0020] In this embodiment, a rotating hole 203 is provided on one side of the connecting rod 2. The connecting rod 2 is fitted onto the cylindrical rod 101 through the rotating hole 203. The cylindrical rod 101 and the rotating hole 203 together form a simple hinge structure, which allows the connecting rod 2 to rotate relative to the pedal 1, realizing the basic functions of frame folding or angle adjustment.

[0021] In this embodiment, one end of the connecting rod 2 is provided with a cylindrical sleeve 4, and a front end sleeve 6 is fitted inside the cylindrical sleeve 4. The cylindrical sleeve 4 and the front end sleeve 6 form an up-and-down sliding structure inside the front end tube, thereby adjusting the height of the front wheel. A fixing component 5 is provided on the cylindrical sleeve 4, which is used to lock the front end angle.

[0022] In this embodiment, the fixing component 5 includes two vertical plates 501. The two vertical plates 501 are located on both sides of the cylindrical sleeve 4. The two vertical plates 501 are respectively provided with through holes 502. The vertical plates 501 and the through holes 502 provide the mounting and guiding foundation for the stepped rod 503. The stepped rod 503 is fitted into the two through holes 502. A third spring 504 is sleeved on the thin end of the stepped rod 503. One end of the third spring 504 is connected to the stepped rod 503, and the other end is connected to the vertical plate 501.

[0023] In this embodiment, a rectangular block 505 is provided at one end of each of the two stepped rods 503. The rectangular block 505 converts the linear motion of the stepped rods 503 into the linear motion of the locking plate 506. A locking plate 506 is provided between the two rectangular blocks 505, and the locking plate 506 is the component that directly performs the locking action.

[0024] In this embodiment, a first slot 401 is provided on the cylindrical sleeve 4, which is the movement channel of the locking plate 506. A second slot 601 is evenly provided on the head sleeve 6, which is the locking point of the locking plate 506. The locking plate 506 passes through the first slot 401 and is locked in the second slot 601.

[0025] In this embodiment, a mounting groove 104 is provided on the top of the pedal 1. The mounting groove 104 is the main body of the battery compartment. First springs 105 are provided on both sides of the inside of the mounting groove 104. The first springs 105 are the main buffer elements. A mounting frame 106 is provided between the two first springs 105. The mounting frame 106 is the battery bracket. Buffer pads 107 are provided on the inner wall of the mounting frame 106. Buffer pads 107 are the secondary buffer elements. A placement groove 108 is provided between the buffer pads 107. A battery 7 is placed in the placement groove 108.

[0026] In this embodiment, a sealing plate 109 is provided on the top of the mounting groove 104, and the sealing plate 109 is a compartment cover.

[0027] The working process of this utility model is as follows: When the lightweight electric scooter frame and structure designed using this solution are in operation or running, if the user needs to adjust the angle, he / she pulls the second baffle 303 outward by hand. The second baffle 303 drives the limiting rod 301 to compress the second spring 304, and causes the end of the limiting rod 301 to exit from the limiting hole 103 on the semi-circular disk 102. After the limiting rod 301 disengages from the limiting hole 103, the constraint between the connecting rod 2 and the pedal 1 is released. At this time, the connecting rod 2 can rotate freely around the axis of the cylindrical rod 101. The user rotates it to the next desired position of the limiting hole 103. When the limiting rod 301 is aligned with the target limiting hole 103, the user releases the second baffle 303. The compressed second spring 304 quickly releases its elastic force, pushing the first baffle 302 and the entire limiting rod 301 toward the semi-circular disk 102. The end of the limiting rod 301 is automatically ejected into the new limiting hole 103. Through the mechanical pin, the connecting rod 2 and the pedal 1 are re-rigidly connected, and the angle is fixed.

[0028] Then, the user pulls the locking plate 506, causing the rectangular block 505 and the step rod 503 to move, compressing the third spring 504. At the same time, the locking plate 506 is pulled out from the first locking slot 401 and the second locking slot 601, releasing the fixation on the front cover 6. Then, the front cover 6 is slid so that the second locking slot 601, which ensures that the front wheel and the rear wheel are on the same horizontal line, corresponds to the first locking slot 401. Then, the locking plate 506 is released, and under the action of the elastic force of the third spring 504, the locking plate 506 is inserted into the first locking slot 401 and the second locking slot 601, completing the fixation of the front cover 6.

[0029] This allows you to adjust the handlebars.
