The invention relates to the technical field of gear motors, and discloses a gear motor for a new energy automobile charging gun, which comprises a gear motor body, and a shell is arranged on the outer wall of the gear motor body. The semi-fluted disc is stressed to be close to the direction of the driving shaft until the semi-fluted disc is attached to the driving shaft, the protection plate is located in the middle of one side of the semi-fluted disc and cannot be attached to the surface of the driving shaft after being stressed and pressed downwards, and the reset spring can stretch the semi-fluted disc under the action of force; after the inner wall of the semi-fluted disc is in contact with the surface of the driving shaft, tooth grooves of the semi-fluted disc are meshed, a power-on path of the semi-fluted disc passes through the semi-fluted disc, so that the upper fluted disc and the lower fluted disc are in contact and are powered on, and after the charging gun is pulled out, a reset spring drives a protection plate to move and drives the semi-fluted disc to be separated from the surface of the driving shaft, so that the semi-fluted disc is powered off. The device prevents idling in the using process of the device and further prevents the gear motor from being damaged by heating, the effect of the device in the using process is improved, and the service life of the device is prolonged.
本发明涉及减速电机技术领域,且公开了一种新能源汽车充电枪用减速电机,包括:减速电机本体,所述减速电机本体的外壁设有外壳。本发明使得半齿盘受力向驱动轴方向靠近,直至与驱动轴贴合,其护板处于半齿盘一侧的中部,其在受力下压后不会与驱动轴的表面贴合,复位弹簧在力的作用下会使得其进行拉伸,在半齿盘的内壁与驱动轴的表面接触后会使其齿槽相啮合,其通电的路径进过半齿盘,使得上下齿盘接触进而通电,在拔出充电枪后其复位弹簧会带动护板运动,带动半齿盘脱离驱动轴的表面,使得其断电,该装置防止了其在使用过程中发生空转,进而导致的减速电机受热损坏,提高了设备在使用过程中的效果延长了使用寿命。
