Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, and in particular to a folding structure for an electric scooter. Background Technology

[0002] Electric scooters, as a portable mode of transportation, are typically equipped with a folding mechanism to achieve space compression. They are products of traditional human-powered skateboards with the addition of an electric motor, and are mainly divided into two types: two-wheel drive and single-wheel drive. The most common transmission methods are hub motors and belt drives, and their main power source is a lithium battery pack. For ease of carrying and storage, most electric scooters include a folding mechanism, which allows the scooter to be folded for convenient storage and transport.

[0003] However, existing electric scooter folding structures have some problems. Some folding structures are prone to loosening and wobbling when unfolded, affecting riding comfort and stability. More concerning, some electric scooters are prone to loosening of the screws due to vibration after prolonged use, causing the folding joint to become loose and posing a safety hazard. This not only affects the folding structure's robustness but may also render the electric scooter unusable, reducing the product's practicality and user experience. Utility Model Content

[0035] Furthermore, in the folding structure of the electric scooter described above, the slot of the U-shaped clip 3 is a V-shaped slot.

[0036] As described above, V-grooves are easy to machine and fit, and provide reliable locking.

[0037] Example 1 Please see Figures 1 to 4 This embodiment provides a folding structure for an electric scooter, including a first folding body 1, a second folding body 2, a U-shaped clip 3, a screw 4, and a knob 5; the first folding body 1 and the second folding body 2 are rotatably connected by a folding pin, the first folding body 1 is provided with a first slot 11, and the second folding body 2 is provided with a second slot 21; one end of the U-shaped clip 3 is engaged with the first slot 11, and the other end is engaged with the second slot 21, and the lower surface of the U-shaped clip 3 is provided with a slot 31; one end of the screw 4 is threadedly connected to the connecting part of the first folding body 1, and the other end passes through the U-shaped clip 3 and is fixedly connected to the knob 5.

[0038] A beveled pin is provided on the first folding body 1. The beveled pin includes a pin body 12 and a spring 13. The pin body 12 is installed inside the first folding body 1 via the spring 13. The bevel of the beveled pin is a wedge-shaped structure, and the material of the beveled pin is spring steel. An elastic washer 6 is provided between the knob 5 and the U-shaped clip 3.

[0039] The first slot 11 and the second slot 21 are axially symmetrical when the first folding body 1 and the second folding body 2 are in the unfolded state. A limit ring 7 is provided on the screw 4. The U-shaped clamp 3 includes a fixing hole through which the screw 4 passes. The outer diameter of the limit ring 7 is larger than the diameter of the fixing hole, and the U-shaped clamp 3 is clamped between the limit ring 7 and the knob 5.

[0040] The slot of the U-shaped clip 3 is located on the bottom side of the U-shaped clip 3. The beveled end of the beveled pin is inserted into the slot of the U-shaped clip 3 to restrict the movement of the U-shaped clip 3 in the vertical direction. One end of the spring 13 is connected to the pin 12, and the other end is connected to the inner wall of the first folding body 1.

[0041] The use of the folding structure in the above-mentioned electric scooter: When the scooter needs to be unfolded, the user rotates the pole and frame to the fully unfolded position, aligning the first and second slots on the first and second folding bodies. Then, the user rotates the knob clockwise to drive the screw to move inward, pressing the U-shaped clip so that its two ends are horizontally inserted and locked into the two slots. At the same time, the beveled pin set in the folding seat will automatically reset under the action of the spring, and its wedge-shaped bevel will be embedded in the slot on the lower surface of the U-shaped clip to form a vertical mechanical interlock, completing the double locking. At this time, the scooter is in a stable unfolded use state.

[0042] When folding is required, the user first slightly rotates the knob in the opposite direction to release the screw pressure. The beveled pin will be pressed down and spring-loaded as the U-shaped latch moves, automatically disengaging from the slot and releasing the vertical lock. Then, continuing to loosen the knob will allow the U-shaped latch to fully exit the horizontal slot, making it easy to rotate the stand and fold the scooter for storage. The entire process of unlocking and locking can be achieved smoothly with a single-direction operation of the knob, making it simple and reliable.
