The connection structure includes a car frame body and two wheels which are arranged on both sides of a car body respectively; a controller capable of controlling the car body to stay in balance automatically is arranged in the car frame body, a hub motor is arranged in each wheel, a rotating shaft is arranged in each hub motor, and the car frame body comprises a left pedal and a right pedal; a connecting rod is arranged in the car frame body, the left side ofthe connecting rod is fixed to the right side of the left pedal, the right pedal is rotatably connected with the connecting rod, a rotating shaft of the left wheel is fixedly arranged on the left pedal, and the right wheel is fixedly arranged on the right side of the connecting rod. The connection structure of the balance car frame aims at achieving the effects that installation is convenient andsteering is flexible.

The invention relates to an insulator with a built-in capacitor EVT component and a processing method thereof. A voltage equalizing cover is added at the upper and lower ends of the EVT to prevent uneven electric fields. A silicone rubber sealing ring is added, the pressure equalizing cover is opened, and the countersunk screw and the EVT grounding insert are screwed together to realize electrical connection. The insulator grounding insert can be welded on the equalizing cover through a vertical wire. The process is simplified. A small sealing ring is arranged in the pressure equalizing cover hole to prevent epoxy from entering during casting. The countersunk head screw is screwed into the head of the high and low pressure insert to increase the sealing ring and relieve the stress at the high and low pressure insert. The EVT signal insert is welded together with the Z-shaped soft wire and the signal insert in the insulator. The flexible wire is easy to install and produce in the mold and is not easily subject to stress interference, ensuring the accuracy of signal transmission. The insulator with built-in high-precision EVT components cast by this method has strong ability to withstand external force interference and reliable performance.
