Description

Scooter with low overturning moment and without hand

Technical Field

The utility model belongs to ground traffic field or toy field specifically are a have low overturning moment and need not hand scooter.

Background

Two-wheeled scooter and three-wheeled scooter have become the children's toys in the world now because simple and easy to learn and light, and electric scooter also becomes the convenient instrument that the adult carries out short distance traffic gradually.

Both manual scooters that provide driving force by stepping on the ground and electric scooters that are driven by electric power have the common disadvantage of requiring both hands of the rider to be held on the handle simultaneously to control the direction of travel, thus making the user unable to liberate their hands when using these toys or vehicles.

In addition, because the handles of the existing manpower scooter and electric scooter are arranged together with the front wheel, when the front wheel encounters an obstacle, the positions of the handles held by both hands of a user have large instantaneous forward impulsive force, the instantaneous forward impulsive force is caused by the change of momentum of the user, the instantaneous forward impulsive force and the moment formed by the instantaneous forward impulsive force to the rotation center of the front wheel form overturning moment, and the overturning moment is large, so that a rider on the scooter can have forward planting accidents along the center of the front wheel.

Based on this, especially propose the utility model discloses, it not only possesses the simple easy and light characteristics of current scooter, can also let user's both hands obtain liberation, need not control the direction and the balance of scooter with the hand when slideing, and more outstanding place lies in, and it has very low overturning moment, even when the front wheel meets the obstacle, the user also is difficult to plant forward.

Detailed Description

The scooter with low overturning moment and no need of walking of the present invention will be further described with reference to the attached drawings 1-3.

As shown in fig. 1-3, the utility model provides a scooter with low overturning moment and without walking comprises a front wheel 10, a rear wheel 20 and a pedal 30, wherein the front wheel 10 is installed at the front part of the pedal 30, the rear wheel 20 is installed at the rear part of the pedal 30, one of the front wheel 10 and the rear wheel 20 is a universal wheel, the other one of the front wheel 10 and the rear wheel 20 is a directional wheel, that is, when the front wheel 10 is a universal wheel, the rear wheel 20 is a directional wheel; when the front wheel 10 is a directional wheel, the rear wheel 20 is a universal wheel, and one of the two wheels must be a direction-changeable wheel. The middle part of the pedal 30 is provided with a rigid or elastic human body trunk blocking part 40, the human body trunk blocking part 40 extends from the rear part of the pedal 30 to the middle part of the pedal 30 in the height direction of the scooter, and the height of the human body trunk blocking part 40 reaches the abdomen or above when the user stands upright.

The utility model discloses in, human trunk barrier 40 is an important invention point, through setting up human trunk barrier 40, makes the user can paste the part of body on human trunk barrier 40 untimely when slideing, thereby is difficult to fall down forward, and the user only needs to keep oneself not to fall down backward when slideing like this, can keep oneself well balanced when slideing, also makes the utility model discloses both hands can be liberated to the scooter without hand. Another invention of the present invention is to set the human body trunk stopping part 40 at the rear part of the pedal 30, but extend to the middle part of the pedal 30 in the height direction, thus not only stopping the trunk of the user, but also minimizing the overturning moment of the scooter. When the front wheel 10 encounters an obstacle, the instant forward impulsive force generated by the user acts on the pedal 30 connected to the trunk blocking portion 40 of the human body, and the distance between the pedal 30 and the rotation center of the front wheel 10 is short, so that the overturning moment generated by the instant forward impulsive force is small, and the user is not prone to forward planting accidents.

The torso stop 40 includes a connecting portion 43, and the connecting portion 43 extends the torso stop 40 from the rear of the deck 30 to the middle of the deck 30. The connecting portion 43 mainly serves as a connecting and transition function, and may be a section of arc-shaped rod or straight rod, or an object with other shapes. In fig. 1, the connecting portion 43 is a circular arc-shaped rod, and in fig. 3, the connecting portion 43 is a straight rod inclined upward.

The torso stop 40 may be a vertical rod standing upright or slightly inclined forward, a barrier, a section of a fence, or a combination of a vertical rod, a barrier and a fence. When the upright stanchion and the baffle are combined together, the human body trunk blocking part 40 can be contacted with the chest and abdomen of a user in a large area, so that the system formed by the user and the scooter is more stable when sliding. Of course, can carry out the fretwork with the baffle, just so can form the structure of similar fence the utility model discloses in, the fence comes than the baffle, has lighter weight for the scooter changes in carrying.

In order to adapt to users with different heights, the length or the height of the trunk blocking part 40 of the human body can be adjusted, so that the scooter is convenient for the users with different heights to use. As shown in FIG. 1, in the embodiment of the stretchable torso stop 40 using the elastic pins 411 in combination with the adjustment holes 421, the elastic pins 411 of the movable section 41 are combined with the different adjustment holes 421 of the fixed section 42 to allow the torso stop 40 to have different lengths. As shown in figure 2, a torso stop 40 is shown that utilizes a combination of uprights and fenders 44 to also enable length adjustment of the torso stop 40.

As shown in fig. 3, in order to quickly and accurately position the feet of the user on the step plate 30, a foot blocking plate 50 is provided at one side of the step plate 30, and the foot blocking plate 50 is provided at the lower portion of the human trunk blocking portion 40.

Alternatively, the front wheel 10 may be 1 universal wheel or 2 universal wheels arranged in parallel, or may be a plurality of universal wheels arranged in parallel, and correspondingly, the rear wheel 20 may be 1 or 2 or even a plurality of directional wheels; of course, the front wheel 10 may also be 1 directional wheel or 2 directional wheels arranged in parallel, or may also be a plurality of directional wheels arranged in parallel, and accordingly, the rear wheel 20 may be 1 or 2 or even a plurality of universal wheels. In general, the number of the front wheels 10 and the rear wheels 20 is preferably not more than 2. Fig. 2 shows a layout in which 2 front wheels 10 and one rear wheel 20 are used, two directional wheels being disposed in parallel at the front end of the step board 30 as the front wheels 10, and one universal wheel being disposed at the rear end of the step board 30 as the rear wheel 20.

When the front wheel 10 is a universal wheel, a foot brake 60 may be installed at the rear of the pedals for braking the rear wheel 20, which is a directional wheel, as shown in fig. 3.

The utility model discloses have low overturning moment and need not hand scooter, do not exclude to adopt electric drive, when needs adopt electric drive, technical personnel in the field can need not creatively to increase electric drive for the scooter.
