Abstract

The invention discloses an automobile waist support motor which comprises a stator, a rotor, a PCB component, a plug connector and a rubber cover, wherein the rotor comprises a rotary shaft, a rotor core and a commutator fixed on the rotary shaft and a winding wound on the rotor core tooth and is characterized in that an inductor clamp slot is formed in the rubber cover; an elastic buckle is arranged on one side of the inductor clamp slot; a barb is arranged at the upper end of the elastic buckle; an inductor is arranged in the inductor clamp slot and fixedly limited by the barb; a torsional spring seat and a carbon brush are also arranged on the rubber cover; the torsional spring seat comprises a cylinder and an arc boss; the cylinder is arranged on the inner side of the arc boss; the cylinder is sleeved with a torsional spring; one end of the torsional spring is connected with the arc boss, and the other end of the torsional spring acts on the carbon brush to guide the carbon brush to fit a current transmission element; the plug connector comprises an end cover and a socket arranged on the end cover; the center of the end cover protrudes outward to form a boss; a metal sheet is inlaid in the boss; and the metal sheet contacts with the spherical surface of the port of the rotary shaft. According to the automobile waist support motor, the inductor mounting is stable to facilitate the mounting of a ball cup, and the PCB component is safe and stable.

Description

technical field [0001] The invention relates to an improved invention in the field of auto parts, in particular to an improved invention for an automotive lumbar support motor. Background technique [0002] At present, the lumbar support of automobiles mostly adopts electric adjustment to improve riding comfort and relieve sedentary fatigue. The power source for driving the lumbar support adopts a dedicated miniature permanent magnet DC motor, which includes a rubber cover assembly and an inductor, a carbon brush, a torsion spring, a plug connector and a PCB assembly installed on the rubber cover assembly. In the prior art, the inductance is installed in the inductance slot of the rubber cover assembly and fixed by glue, or the inductance card slot is used to apply force to both sides of the inductance to fix it. The above two fixing methods are costly or unstable, and are easy to follow the motor. Vibration causes the inductance to disengage or shift; and the installation ...
