The ground grid bumper cars for adults is suitable for indoor use and consists of a floor, a control cabinet, and the bumper cars. Two floor types are available: one utilizes 5mm steel plates and insulation boards, with a 4×14 preservative wood base for fixed use. The other utilizes a 2×1.1m steel, insulation, and composite board structure, ideal for mobile use. The ground grid system utilizes an insulation board between the steel plates to provide power to different electrodes, ensuring conductivity regardless of the car’s position. A rectifier bridge on the bumper car converts the positive and negative polarity, ensuring the car’s operation. The bumper cars are equipped with 48V LED lights and use a 48V 230W brand-name motor. The steering wheel features 360-degree steering for forward and reverse movement. The entire venue is operated from a single control cabinet, which features music, timing, and speed control. It inputs a three-phase 220V or 380V power supply and outputs an AC 32V-52V voltage through a transformer. The ground grid bumper car can be run as soon as it is turned on and does not need to be charged. Because the bottom floor is prone to short circuit when soaked in water, it is suitable for indoor playgrounds.
