Description

Scooter with improved structure

The utility model relates to a scooter, in particular to a scooter with an improved structure.

Because " scooter " has the functions of leisure sports and means of transport in use, and it is very light and handy in its structure, it is very popular among people. At present, the commercially available scooters are mainly composed of skateboards, handle frames and wheels. They are driven by the principle of skateboards. The direction is controlled by the handle frame, so that the wheels can be operated in a certain direction. It is a kind of steering control. A light vehicle with the same method as a bicycle; because the handlebar is used to steer the vehicle, the handlebar must be adjusted up and down according to the height of the user, so that the handles at both ends of the handlebar can be easily grasped and manipulated flexibly, so as to ensure the stability of the handlebar. Control safety, so it is obviously quite troublesome to use, and the length of the handlebar and the design of the lifting and lowering distance must be able to meet the height of tall and short people and chest positions at the same time. Therefore, the structure It is relatively complicated, so that the production is difficult and the cost of the product is increased. It can be seen that its structural composition is not economical; in addition, when the handle frame is used to complete the left and right steering operations, the grip must be quite stable. Scholars often do this), the front wheels must also travel in an irregular shape, causing people to fear that they cannot control the direction, and the panic caused by fear is the main reason for driving collisions. Moreover, once the grip is unstable, it is difficult to complete the correct steering control at all, resulting in improper driving direction and prone to car accidents. Because this control is dangerous, the method of controlling the steering of the skateboard wheels with the handle frame needs to be improved urgently.

The purpose of this utility model is to provide an improved structural scooter with easy and safe steering control, and the wheels can automatically return to the normal position after steering;

Another object of the present utility model is to provide a scooter with an improved structure with a comfortable handle.

In order to achieve the above purpose, the following technical solutions are adopted:

A scooter with an improved structure, including a scooter body with a control lever on the top and a rear wheel pivotally connected to the end of the bottom side, it is characterized in that the front end of the car body is set as a double fork with a downward slope, Two steel rods extending toward the center of the double fork are fixed on the lower section of the control lever; the ends of the double fork are respectively pivoted to one end of the steering link, and the other end of the steering link is connected to the two ends of the tie rod. A short post is protruding from the center of the tie rod; in addition, the left and right front wheels are pivotally connected to the middle of the steering link, and the steel rod is restrained by a ring body, so that the protruding end of the steel rod is just right. It can form a clamping effect on the short column on the tie rod;

It utilizes the displacement force of the control rod to make the double fork tilt, and the pull of the appropriate inclination of the double fork causes the connecting end of the steering link and the double fork to deflect accordingly, so that the steering link on the steering link The front wheels produce a steering effect; when the front wheels turn, the tie rods will be biased, causing the short columns on the tie rods to squeeze the steel rods due to displacement. Once the displacement force of the control lever is released, the steel rods will be compressed and deformed The stored energy is released to make the tie rod return to normal due to the elasticity, and then the left and right front wheels can be pulled back to the forward direction through the steering link, so as to achieve the purpose of automatic front wheel return and sensitive and convenient steering operation.

In the scooter with the improved structure, the top of the joystick is set as a sphere that fits in the hand, and the surface of the sphere is coated with a soft protective cover so that it can be used for wheel steering control, which can achieve comfortable grip and for control purposes.

The utility model utilizes the proper inclination of the double forks at the front end of the car body to flexibly pull the connecting rod to generate action, so that the scooter can complete the steering of the left and right front wheels only by using a small amount of displacement of the control lever, and through the rigidity After the rod is compressed, it forms an elastic force, which automatically returns the front wheels to the normal direction, achieving the effect of easy and safe steering control.

Simultaneously, since the top of the joystick is set as a sphere fit for the hand, and the surface of the sphere is coated with a soft protective cover, it is easy to control.

In addition, using the ring body to cover the steel rod can not only prevent the separation of the steel rod, but also use the positioning adjustment of the ring body to make the steel rod form different degrees of elastic return function, so there is automatic adjustment. Back to the effect of the action.

Describe the utility model in detail below in conjunction with accompanying drawing and preferred embodiment:

Please refer to the accompanying drawings: the utility model mainly includes a scooter body 2 with a control lever 21 on the top and a rear wheel 22 pivotally connected to the end of the bottom side. And at the control lever 21 lower sections, two rigid rods 24 extending toward the center of the double fork are fixedly installed. The two ends of the tie rod 4 are connected, and the tie rod 4 is provided with a short column 41 in the center, and the left and right front wheels 5 are axially connected to the middle section of the steering link 3, and the steel wheel 5 is connected by a ring body 6. The rigid rod 24 is bundled so that the protruding end 241 of the rigid rod 24 can just form a clamping effect on the stub 41 of the tie rod 4 (the combined molding is shown in Figure 2 for details). The inclination of the double fork portion 23 will make the positioning center of the front wheel 5 form an appropriate inclination angle θ with the ground A, and use this inclination angle θ to facilitate the wheel 5 to produce a steering action (see Figure 2-A for details);

When in use, if the control lever 21 is displaced to the right and the force P1 is applied, the direction of the double fork 23 will deviate with the control lever 21, and the steering link 3 and the double fork will be formed by the proper pulling of the inclination angle θ of the double fork 23. The connecting end of 23 deflects thereupon, so that the front wheel 5 on the steering link 3 produces a right-turning action (referring to Fig. 3-A shown), and its car body 2 also forms rightward deflection shape at the same time, so that the human body It can cooperate with the car body 2 to produce an inclination to overcome the centrifugal force, so that the driving effect of man and car is combined; however, when the control lever 21 is displaced to the left to apply the force P2, since the double fork 23 produces a direction offset with the control lever 21, Through the proper pulling of the inclination angle θ of the double fork 23, the connecting end of the steering link 3 and the double fork 23 will be deflected, so that the front wheel 5 on the steering link 3 will turn left (see Figure 3- Shown in B) at the same time, the car body 2 also forms a deflection shape to the left, so that the human body can cooperate with the car body 2 to produce an inclination to overcome the centrifugal force, and the same driving effect of people and cars as one; Right or left rotation, due to the bias of the tie rod 4 will be formed when the front wheel 5 turns, causing the short column 41 on the tie rod 4 to squeeze the steel bar 24 due to displacement, once the displacement of the control lever 21 applies force P1 or After P2 is released, the energy stored in the steel rod 24 is about to be deformed under pressure to release, and the elastic return force P3 of the tie rod 4 is generated, and then the left and right front wheels 5 are pulled back into the forward direction through the steering link 3 ( As shown in Figure 4), the easy and convenient purpose of steering control of the scooter can be achieved like this; and the joystick 21 of the present utility model does not need to be designed to fit the shape and reach the length of the chest position of the human body, because the joystick 21 only needs to be in the hand Within the range that can be grasped, the displacement control effect can be produced, which is a structural design that is quite easy to control.

To sum up, in addition to significantly improving the steering control performance of the scooter, the utility model also provides simple and convenient steering control with a special control rod and connecting rod, and uses the compression elasticity of the steel rod to make the front The wheels are automatically corrected, which is more practical than the existing scooters.
