Automobile glass lifter motor

Abstract

The invention discloses an automobile glass lifter motor. The motor is characterized in that a socket assembly can be split from a brush rack assembly; the socket assembly comprises a socket housing body and a socket electric connection piece; the tail of the socket housing body is connected with a half-surrounding plate; clamping groove holes are arranged in two side plates of the half-surrounding plate; a front protection plate and a back protection plate are arranged in the half-surrounding plate; a first insertion sheet is arranged between the front protection plate and the back protectionplate; the brush rack assembly comprises a brush rack body and a brush rack conducive piece; the outer edge of the brush rack body is connected with a square jack integrated into the brush rack body;the size of the outer edge of the square jack matches the size of the interior of the half-surrounding plate; the inner width size of the square jack matches the leaving size of the front and back protection plates; clamping buckles matching the clamping groove holes are arranged outside the two side walls of the square jack; a second insertion sheet is arranged in the square jack; and an insertion groove matching the first insertion sheet is arranged in the middle of the second insertion sheet. According to the invention, the motor is simple in structure; manufacturing cost is reduced; meanwhile, a phenomenon of gear climbing or gear sheaving of a worm gear is avoided; motor efficiency is improved; and service lifetime of the motor is prolonged.

Description

technical field [0001] The invention relates to a motor, in particular to a motor for an automobile window lifter. Background technique [0002] The lifting and lowering of the car glass is done by the work of the car glass lifter motor. The prior art automobile window lifter motor is composed of a motor part, a brush holder assembly, a socket assembly and a reducer part, the brush holder assembly is arranged between the motor part and the reducer part, and the socket assembly is connected to the brush holder assembly to reduce the speed The machine parts include the reduction box body and the intermeshing transmission worm gear and transmission worm set in the reduction box body. The transmission worm gear is equipped with a load output shaft. The transmission worm gear is a plastic part (which can reduce the working noise), and the transmission worm The right shaft end of the worm is connected with the output shaft of the motor part, the middle of the transmission worm is...

Problems solved by technology

The disadvantage is that the brush holder body of the brush holder assembly and the socket housing of the socket assembly are one-piece injection molding structures, and a one-piece insert is used between the brush holder and the socket. When different main car manufacturers use different docking plugs , the glass lifter motor supporting manufacturers have to make a mold that integrates the socket and the brush holder. This mold has a complex structure, takes a long time, and is expensive; Finally, the worm gear gives a reaction force to the worm, and this reaction force produces an axial component force and a radial component force. When the load moment increases, the radial component force will cause the motor shaft to produce elastic deformation outward, so that the worm gear The meshing point of the worm changes. After the meshing point changes, the efficiency of the motor can be affected by more than 20%. Since the worm gear is made of plastic material, the worm gear will have the phenomenon of worm gear climbing or shaving, which will cause damage to the motor and mechanism failure
