Frog car is also called frog car, frog sports car and frog scooter. Frog car was invented by a foreign inventor, and later it was improved in safety, stability, convenience and flexibility, with independent intellectual property rights and production rights, so it was named frog car. Because it rides like a frog swimming, it is called a frog car.
Second, the principle of frog scooter
The frog car, which integrates mechanics and ergonomics, is the safest and most fashionable fitness sports car in China today. Its structure, safety, flexibility and control are all tested very accurately, and its overall shape is durable and can bear 75 kilograms. Using the principle of sliding left and right, using the combination of outward thrust and inward thrust of both legs to generate thrust, you can naturally move to the suture muscles that are rarely active at ordinary times.
The driving force of the frog car mainly comes from two rear wheels, which are arranged in a universal wheel structure. When exercising, two feet stand on two pedals respectively, and the two legs are repeatedly opened and closed, and the two rear wheels alternately present the shapes of "inner eight" and "outer eight", thus generating driving force.
Third, the characteristics of frog scooter
1, easy to learn: you can easily get on the road even if you can't ride a bike. As long as the feet are clamped, the frog sports car can move forward quickly and walk for a short distance. Anyone who rides it can easily control it in 5 minutes.
2, easy to control: improve the shortcomings of traditional scooters that need to be constantly pushed by feet to move forward, and ride more flexibly, whether it is sliding forward, fast forward, sharp turn, emergency braking, etc. You can do whatever you want. Frog car is not limited by age, sex and height, and indoor and outdoor space is not limited.
3. Family sports: Leisure sports enjoyed by the whole family are indispensable in leisure travel and the coolest practical equipment for exercise and fitness. The "folding collection" can be easily put into the trunk of a car for easy carrying.
4. Healthy exercise: Frog car exercise is a non-impact exercise, especially suitable for children with poor bone development, and muscles that are not active at ordinary times can also be exercised. Women can sculpt buttocks and lower body, men can get enough exercise on their sewing thread to strengthen the body and bones for the elderly, and children aged 4- 10 can get synchronous exercise of left brain, right brain and limbs.
Fourth, the difference between frog scooter and ordinary scooter
1, the motion principle is different.
The frog car makes the universal wheel under the car roll forward through the repeated combination of its legs. The scooter stands on the pedal with one foot and pushes the ground forward with the other foot.
2. Different structural shapes
The frog car has two pedals. One foot steps on one pedal and pushes the car forward through the opening and closing movements of the two feet. A scooter has only one pedal.
3. Different entertainments
Frog car is more entertaining and playable than scooter.
4. Different moving speeds
Usually, the speed of frog car is faster than that of scooter, which can reach 40 km/h.
5. Different categories
Frog car is also a kind of scooter. At first, the traditional scooter was a two-wheeled scooter. Later, in order to increase the stability of the car, it gradually evolved into a three-wheeled scooter. Some people are used to calling frog scooters three-wheeled scooters, frog scooters and so on.
5. Which is better, the children frog scooter or the ordinary scooter?
1, considering the age.
The speed of frog scooter is different from that of ordinary scooter. Usually, the speed of frog car is faster than that of scooter, which can reach 40 km/h, which is still fast and dangerous for younger children.
2. consider physical strength.
Frog scooter has two pedals, one foot stepping on one pedal, and pushing the car forward through the opening and closing movement of the two feet. Children need to stand on the scooter for a long time, which requires high physical strength. Moreover, standing and sliding for a long time will make children's lower limb muscles too developed, which will affect bone development and hinder the normal growth of height.
Some ordinary scooters on the market have two-in-one function, which combines the two functions of sliding and riding into one. When the child is tired, he can automatically switch to riding mode without tools, which is intimate and comfortable. It is more suitable for some younger children to play.
