Still relate to a windscreen wiper, adopt above-mentioned windscreen wiper motor element. Utilize boss and draw-in groove joint, convenient operation is favorable to improving assembly efficiency. The assembly process does not need to be carried out by screws, and the brush holder is prevented from being broken due to the fact that materials are weak, so that the waste of parts is avoided, and the manufacturing cost of the wiper motor is saved. In addition, the assembly efficiency can be improved because no screws need to be screwed on site.
Description
Technical Field
The utility model belongs to the technical field of the windscreen wiper and specifically relates to a windscreen wiper motor element and windscreen wiper.
Background
Generally, a wiper motor brush holder is used for keeping a carbon brush in a brush box stably conducted to current so that the current is conducted to a rotor from the outside, and the brush holder is generally required to be stably fixed on a housing of the motor so as to ensure the stability of the current when the current is conducted through the brush holder.
Typically, the brush holder is fixed by drilling holes in the brush holder and the motor housing and then driving screws into the holes. However, since the brush holder is made of a brittle material and has a weak strength, when the brush holder and the motor housing are fixed, the brush holder may be cracked by a shock when a screw is driven, which wastes parts. In addition, the brush holder fixing screw holes are processed by a machine tool in advance, so that the manufacturing cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a windscreen wiper motor component and windscreen wiper are provided, improve the assembly efficiency of windscreen wiper motor and brush yoke, reduce the breakage rate of brush yoke simultaneously to reduction in production cost.
The utility model provides a technical scheme that its technical problem adopted is: windscreen wiper motor element, including motor and brush yoke, the casing outer wall of motor is provided with columniform boss, the tip of brush yoke is provided with the draw-in groove, and the draw-in groove has that the section is convex inner wall, the boss joint is inside the draw-in groove.
Further, the tip of brush yoke is provided with the bayonet socket with the draw-in groove intercommunication, the width of bayonet socket reduces from the brush yoke outer wall to the draw-in groove lateral wall gradually, just the minimum width of bayonet socket is less than the diameter of draw-in groove.
Further, the top surface of the boss is connected with the side surface through a chamfer.
Further, the boss is integrally formed with the housing.
The wiper adopts above-mentioned wiper motor element.
The utility model has the advantages that: utilize boss and draw-in groove joint, convenient operation is favorable to improving assembly efficiency. The assembly does not need to be screwed, avoids breaking the brush holder due to the fragile material, thereby avoiding wasting parts, and in addition, the manufacturing cost of the wiper motor is saved because no threaded hole is needed to be processed, thereby reducing the working procedures.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a wiper motor assembly, including motor and brush yoke 2, 1 outer wall of casing of motor is provided with columniform boss 11, the tip of brush yoke 2 is provided with draw-in groove 22, and draw-in groove 22 has the section and is convex inner wall, boss 11 joint is inside draw-in groove 22.
The columniform boss 11 can regard as the locating pin for with the draw-in groove 22 joint on the brush yoke 2, during the assembly, with the boss 11 card go into draw-in groove 22 can, the assembly is relatively quick, can improve assembly efficiency. Because the site punching is not needed and the screw is not needed to be punched into the hole, the brush holder 2 can be prevented from being broken due to the fragile material, thereby avoiding the waste of parts and saving the manufacturing cost of the wiper motor.
The clamping groove 22 can be a closed circular through hole, because the outer diameter of the boss 11 is close to the inner diameter of the clamping groove 22, the boss 11 can be clamped into the clamping groove 22 when the boss 11 is coaxial with the clamping groove 22 during assembly, and in order to further improve the assembly efficiency, the clamping groove 22 is taken as a preferred embodiment: the end part of the brush holder 2 is provided with a bayonet 21 communicated with the clamping groove 22, the width of the bayonet 21 is gradually reduced from the outer wall of the brush holder 2 to the side wall of the clamping groove 22, and the minimum width of the bayonet 21 is smaller than the diameter of the clamping groove 22. Because the material of the brush holder 2 has certain elasticity, during assembly, the boss 11 can be moved to the bayonet 21, and then acting force is applied to the boss 11 or the brush holder 2, so that the boss 11 expands the bayonet 21, and the boss 11 penetrates through the bayonet 21 and enters the clamping groove 22. The width of the bayonet 21 is gradually reduced from the outer wall of the brush holder 2 to the side wall of the clamping groove 22, and the width of the bayonet 21 on the outer wall of the brush holder 2 is larger than the diameter of the boss 11, so that the boss 11 can be rapidly placed into the bayonet 21. By adopting the assembly mode, the speed of clamping the boss 11 into the clamping groove 22 can be further improved, the assembly time is saved, and the assembly efficiency is improved.
The top surface of the boss 11 is connected with the side surface through a chamfer which can be a round angle or an oblique angle, so that the worker is prevented from being cut by the edge.
Mode such as boss 11 accessible welding is fixed on casing 1, and is preferred, boss 11 and casing 1 integrated into one piece can obtain boss 11 when carrying out the die casting to casing 1, do not need the later stage to set up alone, reduce production processes, improve production efficiency.
The utility model also provides a windscreen wiper, adopt above-mentioned windscreen wiper motor element can.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
