Description

Technical Field

[0001] This utility model relates to a folding device locking structure, specifically a folding device locking structure based on an electric scooter. Background Technology

[0002] Electric scooters are transportation devices based on traditional human-powered skateboards, with the addition of an electric motor. Electric scooters are generally divided into two-wheel drive or single-wheel drive types, with the most common transmission methods being hub motors and belt drives. Their primary power source is a lithium battery pack. With the increasing popularity and development of electric scooters, their folding convenience has also gradually gained attention.

[0003] Most existing electric scooters consist of a support frame, a board, and handlebars. The support frame is further divided into a connecting frame and a support bracket. To better store the electric scooter, the connecting frame and support bracket are typically designed with a hinge, and then secured using a rotating locking mechanism. However, in actual use, they are prone to loosening, causing them to fail to securely hold together, resulting in the vertical tube collapsing and posing a significant safety hazard. Furthermore, even if the scooter can be folded, the operation remains cumbersome. Therefore, this application designs a folding locking structure for electric scooters. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A folding device locking structure includes a vertical shaft body, a fixed bracket, a folding bracket, a trigger structure, a hook one, and a hook two. The fixed bracket is fixedly installed at the left end of the vertical shaft body. The lower left end of the fixed bracket is movably connected to the lower right end of the folding bracket. Both the upper and lower ends of the folding bracket are fixedly installed with U-shaped connecting edges. A trigger pin is rotatably installed on the upper U-shaped connecting edge. An eccentric wheel body is fixedly installed on the surface of the trigger pin. A trigger structure is movably installed on the trigger pin, and the trigger structure is sleeved on the outside of the eccentric wheel body. The end of the trigger structure away from the eccentric wheel body is bent downwards and fixedly connected to hook one via a hook set screw. A first latch is fixedly installed on the top of the fixed bracket, and a circular slot is provided on the right side of the first latch. The left end of hook one extends into the circular slot. A folding control handle is fixedly installed on the outer end of the trigger pin, and a button mechanism is provided on the folding control handle. The button mechanism cooperates with hook two.

[0007] Preferably, a first safety torsion spring is fitted onto one end of the trigger pin, and the two movable ends of the first safety torsion spring respectively abut against the inside of the folding control handle and the folding card seat.

[0008] Preferably, a second safety torsion spring is fitted at the other end of the trigger pin, and the two movable ends of the second safety torsion spring are respectively fixedly connected to the side of the trigger structure and abut against the folding card seat.

[0009] Preferably, the left end of the trigger structure is fixedly connected to a latch, and the latch cooperates with the left end of the folding control handle.

[0010] Preferably, the button mechanism includes a mounting slot, a movable button, a second hook, a hex socket set screw, and a countersunk Phillips head self-tapping screw. The folding control handle has a mounting slot, and the movable button is slidably mounted in the mounting slot. A support block is fixedly connected to the bottom of the movable button, and the lower end of the support block is fixedly mounted with the second hook by a countersunk Phillips head self-tapping screw. A connecting joint is fixedly mounted on the right side of the fixing bracket, and a second latch is fixedly mounted on the upper end of the connecting joint by a countersunk Phillips head self-tapping screw. A hook groove is opened on the right side of the second latch, and the left end of the second hook extends into the hook groove. A hex socket set screw is fixedly mounted on the right side wall of the mounting slot, and a spring is fixedly connected to the left end of the hex socket set screw, and the other end of the spring is fixedly connected to the side of the support block.

[0011] Preferably, a folding pin is fixedly installed on the lower U-shaped connection of the folding card holder, and a protrusion is fixedly installed on the lower left end of the fixed card holder, and the protrusion is rotatably mounted on the folding pin. A set screw is provided between the folding pin and the protrusion to increase the friction.

[0012] Preferably, the integrated connector is inserted into and fixed inside the vertical tube body of the vehicle pole.

[0013] Preferably, both ends of the trigger pin are fixedly installed with flat-head limit nuts, and the flat-head limit nuts are attached to the folding control handle.

[0014] Preferably, the folding card holder has a break, and the inner walls on both sides of the break have mounting threaded holes, the mounting threaded holes on both sides are aligned, and the inner wall of the folding card holder has a deformation opening, which is far away from the break.

[0015] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0016] (i) In this application, the support block moves to the leftmost position under the elastic force of the spring, that is, the active button is located at the left end of the mounting slot, and the second hook is inserted into the hook groove on the second lock to restrict the movement of the folding control handle so that it cannot be pushed up, and the folding control handle is pressed on the trigger structure. In addition, the first hook is inserted into the circular slot of the first lock to completely restrict the movement of the trigger structure, thereby ensuring the limit of the fixed bracket and the folding bracket, preventing the fixed bracket from falling off during use and causing the vertical tube of the handlebar to hit the pedal or the user, and further improving the safety of using the electric scooter.

[0017] (II) In this application, when folding, moving the active button causes the support block to move the second hook to the right, while the spring is in a compressed state. Then, turning the folding control handle counterclockwise causes the second safety torsion spring to be twisted and stressed, causing the second hook to move with the folding control handle to release the connection between the second hook and the second lock. Continuing to turn the folding control handle causes the trigger pin to rotate. Under the action of the eccentric wheel body, the trigger structure moves, and at the same time, the left end of the folding control handle abuts against the latch on the trigger structure, causing the first hook to move with the trigger structure and disengage from the first lock. At this time, the two safety mechanisms are unlocked, and the fixed bracket can be moved to allow the vertical tube body of the frame to swing from a vertical state to a more horizontal state for placement. The operation is simple, the structural design is reasonable, and the overall structure is beautiful and durable. Attached Figure Description

At this time, the two safety mechanisms are unlocked, and the fixed bracket 2 can be moved to swing the vertical tube body 1 from a vertical state to a horizontal state for placement. The operation is simple, the structure is reasonably designed, and the overall structure is beautiful and durable.
