U-shaped push rod for automobile electric tail-gate system

Abstract

The invention discloses a U-shaped push rod for an automobile electric tail-gate system, relates to the technical filed of automobile precision instruments, in particular to the U-shaped push rod forthe automobile electric tail-gate system. The U-shaped push rod comprises a shell, a permanent magnet motor fixedly installed in the shell, a transmission device is fixedly connected to the rotating shaft of the permanent magnet motor in a sleeving mode, a driving gear group is fixedly connected to the rotating shaft of the transmission device in a sleeving mode, and the driving gear groups are engaged with a driven gear group. According to the U-shaped push rod for the automobile electric tail-gate system, after the rotating shaft of the permanent magnet motor is connected with the transmission device, the driving gear group is driven to rotate, by using the rotation inertia and centrifugal force generated by the rotation of a first helical gear and a second helical gear which are arranged in the transmission device, the torque of a main oblique column rod is auxiliarily increased, the damage to the permanent magnet motor is lowered, meanwhile the pushing force of an external sleeve pipe to a vehicle door is improved, and the supporting force of the U-shaped push rod is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automotive precision instruments, in particular to a U-shaped push rod used in an automotive electric tailgate system. Background technique [0002] The push rod system of the electric tailgate of the car is composed of inner oil, outer casing, and motor gearbox assembly. The motor gearbox assembly drives the outer conduit to do reciprocating linear motion through the drive screw, and the tail box is realized under the action of the movement of the motor-driven outer casing. Therefore, the gear reduction motor of the tailgate push rod must have the characteristics of large torque. When the motor is used for a long time, the rotor of the motor will be damaged, which reduces the torque of the motor and the service life of the push rod. After long-term rotation of the screw rod and the sleeve rod, the tooth pattern on the surface of the screw rod will wear out, causing the screw rod to wear. The pushing and...

Problems solved by technology

When the motor is used for a long time, the rotor of the motor will be damaged, which reduces the torque of the motor and the service life of the push rod. After long-term rotation of the screw and the sleeve rod, the tooth pattern on the surface of the screw will wear out, causing the screw to The pushing and stabilizing effect of the sleeve rod are reduced
