[0011] Beneficial effect: The utility model relates to a vehicle refrigerator that can be opened and closed automatically. A driving gear meshing with a rack is installed on the output shaft of the motor. The driving gear is connected and fixed to the drawer. The driving gear is driven to rotate forward or reversely by controlling the forward and reverse rotation of the motor. The driving gear meshes with the rack to convert the rotational motion into linear motion to drive the drawer inside the vehicle refrigerator. One side of the drawer is connected and fixed to the door body to realize the electric opening and closing of the vehicle refrigerator. A weight-reducing groove is arranged on the rack. The weight-reducing groove can not only reduce the weight of the rack, but also improve the resistance of the rack to deformation to a certain extent. The sliding range of the drawer is limited by cooperating with the sensing device and the two blocks. A travel switch is installed on the inner side of each block. There are two travel switches in total, which correspond to the fully closed position and the fully open position of the drawer respectively. When the sensing device contacts the travel switch, it indicates that the drawer has slid to the specified position. The travel switch will transmit this information to the display control panel, and the display control panel will display the information that the drawer has slid into place.
