The car wiper reducer shell has the advantages that the positioning pillars are arranged on the bottom portion of the installation groove of the motor flange seat in the concave mode, a positioning rod can be locked into a positioning groove of a motor brush, the positioning of the motor bush is achieved, the motor brush is prevented from shaking along with the rotation of a motor shaft, noise can be lowered effectively, and the structure is simple and reasonable.
Description
Technical field
The utility model relates to a kind of car windshield wiper reduction box casing.
Background technique
Existing car windshield wiper reduction box casing, comprise enclosure body, be provided with to connect the motor flange seat of motor on this enclosure body, the middle part of this motor flange seat is concaved with mounting groove, the middle part of this mounting groove is equipped with motor axis hole, also is provided with mounting hole on the described motor flange seat.When mounted, the brush of motor part can stretch in the mounting groove, and the motor shaft of motor places motor axis hole, and the casing of motor is fixed by screws in the mounting hole place of motor flange seat, thereby realizes the installation of motor.Because brush is to fix and do not fix with reduction box casing with motor, in use, the motor shaft of motor rotates, and drives easily brush and slightly rocks, thereby produce noise easily.
Summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, it is a kind of simple in structure, easy to use and have a car windshield wiper reduction box casing of position structure that the utility model provides.
The technical scheme in the invention for solving the technical problem is: a kind of car windshield wiper reduction box casing, comprise enclosure body, be provided with to connect the motor flange seat of motor on this enclosure body, the middle part of this motor flange seat is concaved with mounting groove, the middle part of this mounting groove is equipped with motor axis hole, also be provided with mounting hole on the described motor flange seat, the bottom of described mounting groove convexes with at least two locating columns.
Further, described locating column has three, and wherein two described locating columns are positioned at both sides and the Central Symmetry setting of described motor axis hole.
Further, be concaved with the first closure gasket groove on the end face of described motor flange seat between described mounting hole and mounting groove, the bottom of described mounting groove is concaved with the second closure gasket groove between described motor axis hole and described locating column.
Further, the bottom of described mounting groove also is concaved with two sealed grooves, and these two sealed grooves are positioned at both sides and the Central Symmetry setting of described the second closure gasket groove.
The utility model when mounted, the end face of the brush of motor is provided with locating slot, the motor shaft of motor stretches in the motor axis hole, the brush of motor stretches in the mounting groove, locating column on the mounting groove places in the locating slot, can position brush, thereby preventing from driving in the motor shaft rotation process brush rocks, can effectively reduce noise, and locating column can be arranged to 3, realizes three points location, locates more reliable, the casing of last motor is fixed by screws in the mounting hole place of motor flange seat, thereby realizes the installation of motor.
Because the end face of motor flange seat is provided with the first closure gasket groove, the bottom of mounting groove is provided with the second closure gasket groove, in the first closure gasket groove, install first seal ring, install second seal ring in the second closure gasket groove, first seal ring seals between the joint to the casing of motor flange seat and motor, second seal ring seals good sealing effect between the joint to the mounting groove of the brush of motor and motor flange seat.
Because the bottom of mounting groove also is concaved with two sealed grooves, in two sealed grooves, install sealing column, sealing column seals between the joint to the brush of the mounting groove of motor flange seat and motor again, can realize for the second time sealing, and sealing effect is better.
The beneficial effects of the utility model are: adopt said structure, in the mounting groove of motor flange seat, convex with locating column, locating column can snap in the locating slot of motor brush, realization is to the location of brush, prevent that brush from rocking because of the rotation of motor shaft, can effectively reduce noise, and simple and reasonable.
