Description

TECHNICAL FIELD

[0001] The utility model relates to a wiper component, in particular to a brush head seat applicable to various brush heads and a wiper structure with the brush head seat. BACKGROUND

[0002] The existing aircraft, ships, vehicles and other vehicles usually need to be operated by personnel so that the vehicles can travel safely. In order to provide a clear view for the driver, most of the glass windows of the vehicles are provided with a wiper blade. The wiper blade is installed on a rocker arm of each vehicle through a brush rod. The wiper blade can be moved back and forth on the glass to remove water or dirt attached to the glass, so that the driver can have a clear view.

[0003] Generally, the rocker arm and the brush rod need to be connected through a brush head and a brush head seat. The brush head is usually attached to the rocker arm, and the brush head seat is usually attached to the brush rod. Therefore, when the vehicle drives the rocker arm to swing back and forth, the rocker arm can drive the brush rod and the wiper blade to move back and forth on the glass to remove water or dirt attached to the glass.

[0004] Due to the force of the rocker arm swinging back and forth and the resistance of the wiper blade moving back and forth on the glass, the brush head and the brush head seat between the rocker arm and the brush rod are prone to loosen, so that the wiper blade cannot effectively remove the water or dirt attached to the glass, and the driver cannot have a clear view, resulting in the need to replace the brush rod and the wiper blade.

[0005] The manufacturers of the existing vehicles of various types manufacture vehicles of different types, so the brush heads and brush head seats provided are also of various types and specifications. Therefore, the sellers need to stock various types of brush rods and wiper blades, and the consumers need to compare the matching brush heads and brush head seats, so that the brush heads and brush head seats can be combined with the rocker arms of the existing vehicles. SUMMARY

[0006] To solve the above problems, the utility model provides a brush head seat and a wiper structure with the brush head seat, which can be connected with various different brush heads, so that the sellers only need to stock a single brush head seat.

[0007] The utility model provides a brush head seat and a wiper structure with the brush head seat, which can make the consumers conveniently and quickly select and replace the brush rod and the brush head.

[0008] The directionality or its approximate phrases, such as "front", "back", "upper (top)", "lower (bottom)", "inner", "outer", "side surface" and the like, are mainly referenced to the direction of the attached drawings, and the directionality or its approximate phrases are only used to assist in description and understanding of the embodiments of the utility model, and are not used to limit the utility model.

[0009] The brush head seat of the utility model, comprising: a base, having two opposite end edges, the base has a pair of embedding grooves at the bottom, the two embedding grooves penetrate the two end edges and are located on the inner wall surface of the two side walls of the base, the top of the base is adjacent to one end edge and has two combination seats, the inner surface of the two combination seats each has a protrusion, the bottom of the two protrusions and the top surface of the base are not connected and each form a gap, the top surface of the base further has a convex body and a buckle, the convex body protrudes on the top surface of the base, the buckle has a protruding hook portion; and a connector, combined on the top of the base, the connector includes a bottom plate and two side plates, the two side plates are erected on the bottom plate, the first end of the bottom plate extends into the gap at the bottom of the two protrusions, the second end adjacent to the bottom plate has a combination hole, the combination hole penetrates the upper and lower surfaces of the bottom plate, so that the convex body and the buckle protrude from the combination hole, and the hook portion of the buckle is buckled on one side of the combination hole; the two side plates have a connecting column between them, and the two side plates each have a ring body with a protruding outer surface.

[0010] The wiper structure of the utility model, comprising: one of the above brush head seats; a brush rod, having an embedding part and a wiper blade, the embedding part is embedded in the pair of embedding grooves of the base, and the wiper blade protrudes at the bottom of the brush rod; and a brush head, pivoted to the connecting column of the connector by a pivot slot, and the brush head has a clamping block clamped with a clamping groove of a rocker arm.

[0011] The wiper structure of the utility model, comprising: one of the above brush head seats; a brush rod, having an embedding part and a wiper blade, the embedding part is embedded in the pair of embedding grooves of the base, and the wiper blade protrudes at the bottom of the brush rod; and a brush head, pivoted to the connecting column of the connector by a pivot slot, and the brush head has a clamping block clamped with a clamping groove of a rocker arm.

[0012] Therefore, the brush head seat and the wiper structure having the same can be combined with the connector to form a brush head seat, the base can be embedded with a brush rod, and the connector can be combined with one of various types of brush heads, and the brush head is combined with the rocker arm of each vehicle.
