Abstract: The invention discloses a bracket. The new-type infant larry bracket comprises two placing frames. The two frames are movably arranged on the right base and the left base respectively. The right base and the left base have a connecting section. The right base and the left base can be disassembled and fixed at both ends of the connecting bridge section. The two placing frames can slide forward and backward on the right base and the left base respectively. The utility model has a reasonable structure, which can help a baby to sleep smoothly and autonomously and does not need parents to accompany for a long time.

Abstract: A punching bag training system has a monitoring device, a group display, and training stations.

Abstract: The invention discloses a swing car controller, comprising left and right motor control boards, the left is arranged close to the left motor, and the same for the right; the left connects the left motor and a left car body attitude sensor; the left car body attitude sensor collects the left pedal attitude information and sends to the left motor control board, which controls the left motor for normal operation through a left motor vector drive circuit. The motor control board is divided into left and right parts; the left collects the left pedal information and controls the left motor to operate normally, and the same for the right; the distances between the motor phase wires and HALL wires on both sides to the left and right control boards are the shortest, which reduces line impedance and line interference, improves vehicle control performance, and makes vehicle operation more stable.
