The ground grid collision car is driven by a DC motor, and AC power is converted by a control device to be transmitted from the electrodes to the motor of the collision car, which drives the wheels to operate through a deceleration structure. Tourists sit in the car and use foot switches to control driving and parking, and turn the steering wheel to control the direction of travel. Due to the presence of a buffer (tire) beside the car, collisions can occur freely, with a speed of approximately 8 kilometers per hour. The body of a bumper car is generally made of fiberglass demolded material. The reinforcing material in fiberglass is glass fiber. Glass fiber is an inorganic fiber material made by pulling or blowing molten glass. Its main chemical components are silicon dioxide, aluminum oxide, boron oxide, magnesium oxide, sodium oxide, etc. The fibers produced include long filaments, short filaments, and flocs, with a diameter generally ranging from 5-80 microns and a thickness only as thick as human hair. The tensile strength of glass fiber with a diameter of 10 microns is 3600 megapascals, which is equivalent to being able to withstand a tensile force of 360 kilograms per cubic millimeter of cross-sectional area. Bumper cars belong to special equipment, and our company's products are manufactured, installed, modified, maintained, inspected, and managed in strict accordance with relevant standards for Chinese special equipment bumper cars.
