Description

Scooter folding device

The utility model relates to a scooter, in particular to a folding device for the scooter.

Nowadays, the very popular scooter is mainly equipped with pulleys at the front and rear ends of the frame, and a pedal is set on the middle section. When the front wheel turns, step on the pedal with one foot and push the other foot on the ground. When the scooter has the inertial power to slide forward, you can put your feet on the pedal and let it slide. When the speed of the scooter slows down Or when it is about to stop, the above actions and repeated operations can be repeated, so that the scooter has the effect of saving labor and moving, and has the effect of sports and entertainment.

Because the scooter has a handle and the standpipe steering structure of the interlocking pulley takes up a lot of space, it is not very convenient to store and carry. Therefore, some operators set the standpipe as a bendable and foldable form that is pivotally connected to each other, such as Taiwan Announcement No. 377689 The new patent case is mainly to set a connecting seat at the end of the pedal of the car body, and extend a connecting frame with a shaft hole and a round hole at the bottom of the handle. The connecting seat and the connecting frame are penetrated by the bolt shaft, and the connecting seat is provided There are arc-shaped rail grooves, and there are two stop grooves facing downward in the arc-shaped rail grooves, and a stop post is installed in the arc-shaped rail grooves corresponding to the shaft holes for positioning, and a tension spring is provided to hook the two ends of the springs respectively. Arresting the middle section of the bolt shaft and the stopper column, the elastic tension formed by the tension spring keeps the stopper column embedded in the stop groove and locked in position under normal conditions. When the stopper column moves out of the stop groove, the stopper column is centered on the bolt shaft Sliding upward or downward according to the arc-shaped rail groove, and the retaining column is buckled in the retaining groove by the tension spring to form the positioning of the scooter standing or folding.

The conventional scooter folding structure mentioned above only uses a tension spring to fasten the retaining column to the retaining groove to form a single positioning function, and lacks another auxiliary safety device to ensure locking, which easily makes people feel insecure.

In view of this, the purpose of the present utility model is to provide a folding device for a scooter that has double positioning functions, is stable to stand, and is convenient to fold and operate.

In order to achieve the above object, the solution of the utility model is: a folding device for a scooter, the front tube extends a bracket and connects to a positioning seat fixed at the front end of the pedal to form a form that can be folded and folded, wherein the scooter The bracket of the front pipe is provided with a pivot hole at the end, a long slot hole is formed on the pivot hole and a connecting rod is set inside the frame body, and a slide groove is formed on the upper side, and a pressing seat and a push plate are respectively installed inside it. The outer side is locked with a fixed bolt; the positioning seat at the front end of the pedal is provided with shaft holes at the lower ends of the seat plates on both sides, and an arc-shaped groove is formed on the upper side of the opposite shaft hole, and the front and rear ends of the arc-shaped groove face upward to form the first groove respectively. , the second groove, the shaft hole at the lower end is docked with the pivot hole at the end of the bracket to be pivotally pierced, and the long slot hole of the bracket corresponds to the arc groove of the positioning seat, and a quick-release bolt for piercing the sleeve is installed, and the sleeve and the A stretch spring is set between the connecting rods and the casing is stretched and abuts against the pressing seat.

In the folding device of the scooter mentioned above, the chute of the bracket is provided with a spring that pushes the pressure seat and the push plate upward and can automatically reset.

After adopting the above-mentioned scheme, due to the expansion and retraction of the front tube relative to the pedal, the above-mentioned bracket is fixed upwardly with the casing of the quick-release bolt relative to the first and second grooves of the positioning seat and the quick-release bolt is pressed tightly. , or to move down the push plate together with the pressure seat to push the bushing away from the first and second grooves, and can be rotated and retracted to achieve double positioning, stable erection and convenient folding operation.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a schematic diagram of the locked state of the utility model;

Fig. 3 is a schematic diagram of the release action of the utility model;

Fig. 4 is a schematic diagram (1) of the folding action of the present utility model;

Fig. 5 is a schematic diagram (2) of the folding action of the present invention.

As shown in Figure 1, the utility model is mainly connected with the positioning seat 4 formed opposite to the front end of the pedal 3 by obliquely extending a bracket 2 from the front pipe 1 of the car, wherein:

The support 2 of the front tube 1 is obliquely shaped and is provided with a pivot hole 21 at the end, a slotted hole 22 is formed on the pivot hole 21 and a connecting rod 23 is established inside the frame body, and a chute 24 is formed on the upper side for A pressing seat 25 and push plate 26 are installed on the inside and outside respectively to lock with fixed bolt 27, and a spring 28 is provided with the bottom of the groove to push the pressing seat 25 and push plate 26 to reset automatically; Established positioning seat 4 is to establish an axis hole 41 at the lower end of both side seat plates, and an arc groove 42 is formed on the upper side of the relative axis hole 41, and the front and rear ends of the arc groove 42 upwardly form the first groove 421, The second groove 422, on the positioning form in which the support 2 and the positioning seat 4 are pivotally connected, the lower end shaft hole 41 is provided for the butt joint of the pivot hole 21 at the end of the support 2 to be pierced by a pivot 5, and the long slot hole 22 of the support 2 is correspondingly positioned The arc-shaped slot 42 of the seat 4 is provided with a quick-release bolt 6 that penetrates the sleeve 61, and a tension spring 7 is provided between the sleeve 61 and the above-mentioned connecting rod 23, so that the sleeve 61 is pulled and abutted against the pressure seat. 25.

Implemented by the above-mentioned design assembly, when the scooter is erected and fixed with the front tube 1 relative to the pedal 3, as shown in Figure 2, the front tube 1 docks with the pivot hole 21 at the end of the bracket 2 to the pivot hole 41 of the positioning seat 4. The shaft 5 rotates as a central axis, so that the bottom end of the bracket 2 abuts against the bottom surface of the positioning seat 4. At the same time, the tension spring 7 in the bracket 2 pulls the sleeve 61 of the quick release bolt 6 to arc along the positioning seat 4. The upper edge of the groove 42 is snapped into the first groove 421 at the front end to form the first fixation, and then the quick release bolt 6 can be pressed against the positioning seat 4 to clamp the bracket 2 to form the second locking effect, and It has double insurance safety function.

When folding, as shown in Figure 3, the quick release bolt 6 can be loosened first, so that the positioning seat 4 and the bracket 2 are no longer clamped, and then the push plate 26 is pushed down to push the internal pressure seat 25 together. The sleeve 61 of the quick release bolt 6 descends and breaks away from the first groove 421, and the bendable support 2 rotates to make the sleeve 61 slide along the arc groove 42 (as shown in FIG. 4 ). , as shown in Figure 5, the sleeve 61 of the quick-release bolt 6 that is lowered under pressure is pulled by the tension spring 7 inside the bracket 2 and automatically slides in when it fits the second groove 63 at the rear end of the arc-shaped groove 42 snap in to secure its folded state.
