Description

Technical Field

[0001] The utility model relates to a new energy vehicle refrigerator, in particular to a new energy vehicle refrigerator with a fully automatic door opening and closing power system lower disassembly structure. The vehicle refrigerator can also be used on oil vehicles. Background Art

[0002] Existing car refrigerators with automatic door opening systems all require after-sales service. The motor is the power system for automatic door opening. When the motor fails and needs to be repaired or replaced, the motor needs to be removed from the car refrigerator. However, existing car refrigerators do not have a structure that facilitates the removal of the motor. Often, when the motor is damaged, the drawer needs to be pulled out to remove the motor. For example, Chinese patent No. ZL202410210427.8 discloses an air-cooled car refrigerator with an electric door opening function. The air-cooling fan blows cold air into the interior of the refrigerator body in two ways by blowing air. The refrigerated drawer is installed inside the refrigerator body by pulling and pulling the refrigeration box seat. The nylon pull rope is released and pulled under the cooperative drive of the driving wire wheel and the reduction motor to realize the automatic opening and closing drive of the refrigerated drawer. The door body adopts a wire wheel type opening drive scheme, and the nylon pull rope is limited by the pulling. The rear part of the refrigerated drawer of the car refrigerator is provided with a storage spring, a driving wire wheel and a reduction motor. When the motor is damaged, the drawer needs to be pulled out to remove the motor, which is not convenient for after-sales maintenance personnel to disassemble and repair the motor.
