Description

A scooter folding device

The utility model relates to a folding device for a scooter, in particular to a folding device for a scooter, that is, the user only needs to move the brake lever to the outside to operate with one hand without pinching the user's fingers. .

In modern society, leisure life has gradually been valued by people, and the work pressure accumulated all day long, most of them want to relieve it through holidays. Going to the countryside for picnics and outings are good ways to relieve pressure, but sometimes Give up due to the long distance, therefore, people have developed a scooter that can have both leisure and sports and can also be used for transportation, so as to adapt to the needs of the trend.

Traditional scooter, please refer to shown in Fig. 1, Fig. 2 (Taiwan Patent Case No. 087215733), it is mainly extended with the handle and the step of the joint frame 5 by the bottom, and the handle and the step can be locked. The connection seat 6 is composed of; the bolt shaft 71 is used to penetrate the connection seat 6 and the joint frame 5, and an arc-shaped rail groove 61 is correspondingly divided on the connection seat, and a stop groove 62 is preset on the arc-shaped rail groove, and A stop post 72 is positioned in the arc-shaped rail groove, and then the ends of the tension springs 73 are respectively hooked on the middle section of the bolt shaft 71 and the stop post 72, and the elastic tension formed by the stretch spring makes the stop post 72 keep the locked state embedded in the stop groove 62 during normal state; if the stop post is moved out of the stop slot, the stop post can slide on the arc track groove, so as to achieve the effect of folding and positioning the handle. However, the above-mentioned scooter is not as ideal as expected in actual use, and its shortcomings are summarized as follows:

1. Troublesome operation:

The above-mentioned known folding structure of the scooter is based on the elastic tension formed by the tension spring, so that the retaining post 72 remains in the locked state embedded in the stop groove 62 when it is in a normal state. Use the same force to move the retaining column out of the stop groove, so that the retaining column 72 can slide on the arc-shaped rail groove 61 to achieve the folding position of the handle; thus, when folding, the user must straddle the step On both sides, use both hands to pull up the retaining post, instead of operating the folding of the scooter with one hand from the side of the scooter, causing trouble in folding, and it is also easy to cause the handle to hit the user due to improper control.

2. It is not safe to use:

The known scooter must be controlled by the user with both hands to pull up the retaining post to achieve the folding of the handle. , the elastic force of the tension spring itself is extremely large, so the user must apply a large force to pull up the retaining column, so that it is easy to pinch the thumbs located at the two inner ends when pulling up, resulting in trouble in use. not safe.

The purpose of this utility model is to provide a simple and safe operation when folding the scooter. It only needs to move the brake lever to the outside to drive the joint to compress the spring, so that the brake shaft is separated from the positioning hole of the connecting seat, and the The scooter folding device that folds the handle bar toward the stepping seat will not pinch the user's fingers.

The purpose of this utility model is achieved like this: a kind of scooter folding device, the bottom end is provided with the handle lever of front wheel and joint frame, and the tail end is provided with the tread of rear wheel, and a connecting seat connects handle lever with The step is locked, and there are quick-release handles on both sides of the connecting seat; an inclined groove is provided at the front end of the connecting seat, and a locking structure that is locked with the connecting seat is provided inside the connecting frame, and The cooperating connecting seat is provided with an upper and lower positioning hole for the clamping structure on one side, and an arc-shaped sliding groove is provided on the other side; the clamping structure includes a spring located inside the joint frame, and passes through the joint frame and The brake rod of the spring, the brake rod is provided with a joint at the other end passing through the spring, and the joint can be locked in the upper positioning hole of the connecting seat by the stretching force of the spring, and the joint frame is locked on the connecting seat .

The utility model has the advantages that the user only needs to move the brake lever to the outside to operate with one hand without pinching the user's fingers. Not only is it suitable for scooters, but it can also be used in exactly the same way on similar functional parts such as foldable bicycles where the handle is folded as an important requirement.

The accompanying drawings are as follows:

Fig. 1 is the perspective view of known scooter folding device;

Fig. 2 is the plane action figure of known scooter folding device;

Fig. 3 is a three-dimensional exploded view of a scooter folding device proposed by the utility model;

Fig. 4 is a three-dimensional combined view of a scooter folding device proposed by the utility model;

Fig. 8 is a side sectional view when the engaging frame 7 of the scooter folding device in Fig. 7 slides;

Fig. 9 is a partial plane embodiment diagram of a scooter folding device proposed by the utility model.

As shown in Fig. 3, Fig. 4 and Fig. 9, a kind of scooter folding device proposed by the utility model is composed like this, the bottom end is provided with the front wheel 11, and the rear end is extended with the handle lever 1 of the engaging frame 12, The tail end is provided with the step 2 of the rear wheel, and the shaft bolt 36 is used to pass through, and the connecting seat 3 locks the handle lever 1 and the step 2, wherein:

The connecting seat 3 is provided with arc grooves 31 on both sides for the sliding of the quick-release handle 32 , and the quick-release handle 32 can be used for pressing and positioning the connecting frame 12 and the connecting seat 3 .

The joint frame 12 is provided with an obliquely inclined groove-shaped part 121 at an appropriate position at the front end, and the interior of the joint frame 12 is provided with a locking structure 4 that is clamped with the connection seat 3, and is provided on one side with the connection seat 3. The upper positioning hole 33 and the lower positioning hole 34 are used for the locking structure, and an arc-shaped sliding groove 35 is provided on the other side.

The locking structure 4 includes a spring 41 located inside the joint frame 12, and a brake lever 42 passing through the joint frame 12 and the spring 41. The brake lever 42 locks a joint 43 at the other end passing through the spring, and the joint 43 can be locked in the upper positioning hole 33 of the connecting seat by the stretching force of the spring 41 , so that the tension frame 12 is locked on the connecting seat 3 .

Please refer to Figures 5 to 8 again. When the user wants to fold the handle lever 1 toward the step 2, the user only needs to move the brake lever 42 to the outside to drive the joint 43 to compress the spring 41, so that the joint 43 is disengaged. The upper positioning hole 33 of the connecting seat (as shown in Figures 5 and 6) can be used by the connecting frame to drive the handle lever to fold towards the step; when the handle lever and the step are folded together, release the brake shaft 42 , at this time, the joint 43 can be positioned in the lower positioning hole 34 of the connecting seat by the restoring force of the spring 41 (as shown in FIGS. In this way, one-handed operation can be achieved without pinching the user's fingers.

In addition, the scooter folding device proposed by the utility model is not only suitable for use on the scooters listed above, but also can be used on similar functional parts such as folding bicycles that generally require the folding of the handle as an important appeal. use.
