Detailed Description

In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below:

referring to fig. 2 and 3, which are preferred embodiments of the wiper joint of the present invention, the wiper joint may be configured to be combined with a swing arm 9, so that after the wiper joint is combined with a wiper rod of a wiper, the swing arm 9 may drive the wiper rod to swing, the wiper joint includes a top plate 1 and two side plates 2, and the two side plates 2 are respectively connected to two opposite sides of the top plate 1.

In detail, each side plate 2 may have a fixed end 2a and an engaging end 2b opposite to each other, the fixed end 2a has a fixed protrusion 21, and the fixed protrusion 21 may protrude from the fixed end 2a in an extending direction X passing through the fixed end 2a and the engaging end 2b, thereby being capable of being coupled to the swing arm 9. The engaging end 2b can have a spring 22 in the extending direction X, and a gap S1 is formed between the spring 22 and the top plate 1, so that the spring 22 forms an elastic deformation space on the side facing the top plate 1, and the spring 22 can be pressed to elastically deform in the direction of the gap S1. In addition, the other side of the spring 22 opposite to the gap S1 has an engaging space S2 for engaging the rocker arm 9. In this embodiment, a free end 22a of the pressing member 22 may have an abutting flange 221 protruding toward the engaging space S2, and the abutting flange 221 may limit the engaging space S2, so that the wiper blade connector may be further firmly coupled to the swing arm 9 (described in detail later).

Each side plate 2 may have a pivot portion 23, the pivot portion 23 may be a shaft hole, and the pivot portion 23 may be a blind hole formed on the inner surface of the side plate 2 or a through hole penetrating through the side plate 2; in addition, the pivot portion 23 may also be a pivot protruding from the inner surface of the side plate 2, but the utility model is not limited thereto. When the wiper joint of the present invention is actually used, the wiper joint can be covered on a fixed seat 31 of a brush rod 3, and the wiper joint can be pivotally connected with the fixed seat 31 through the pivoting part 23 of each side plate 2, so that the wiper joint can pivot relative to the fixed seat 31. In this embodiment, the fixing base 3 may have a pivot 32 for passing through the pivot portion 23 and forming a pivot connection therewith; however, the fixing base 31 may also be correspondingly provided with a shaft hole for the pivot portion 23 to pass through.

With the above structure, referring to fig. 2, when the wiper joint of the present invention is actually used, the swing arm 9 can be engaged and combined in a conventional manner, so that the swing arm 9 can be linked to the wiper and the wiper rod 3 to swing when the swing arm 9 is operated, in detail, an engaging member 913 is disposed between the first end 91a and the second end 91b of the connecting portion 91 of the swing arm 9, and the engaging member 913 has an engaging groove 914 facing the second end 91 b. The sliding portion 92 has two opposite side sliding plates 921, the end edge of each side sliding plate 921 extends towards the opposite side sliding plate 921 respectively to form a first limit block 921a, and a second limit block 921b of the first limit block 921a extending towards the sliding portion 92, so that a sliding slot 921c is formed between the second limit block 921b and the side sliding plate 921, thereby, the side piece 912 of the connecting portion 91 can be located in the sliding slot 921c, and the sliding portion 92 slides relative to the connecting portion 91.

Referring to fig. 3 and 4, when the wiper blade joint of the present invention is assembled with the swing arm 9, the fixing protrusion 21 of the fixing end 2a of each side plate 2 can be engaged with the engaging groove 914 of the swing arm 9, so that the wiper blade joint is located between the two side plates 912 of the connecting portion 91, and the wiper blade joint can be positioned in the connecting portion 91 through the fixing end 2 a.

Referring to fig. 5, after the wiper joint is positioned at the connecting portion 91, the sliding portion 92 can slide toward the first end 91a of the connecting portion 91, and the second stopper 921b at the end edge of the side sliding plate 921 of the sliding portion 92 is driven to slide on the inner side surface of the side plate 912 of the connecting portion 91, at this time, the second stopper 921b can press against the abutting flange 221 of the free end 22a of the elastic member 22, so that the elastic member 22 can elastically deform toward the gap S1, and the second stopper 921b of the sliding portion 92 can be forced into the engaging space S2 at the lower side of the elastic member 22, thereby the wiper joint can be fixed to the connecting portion 91 through the sliding portion 92.

In summary, the wiper joint of the present invention can fix the wiper joint in a forced manner by the sliding portion of the existing rocker arm through the snap-in ends respectively having the spring pieces, so that the wiper joint can be combined with the rocker arm. Compared with the prior wiper joint which is protruded to the assembly hole of the top plate of the connecting part through the pressing block and the clamping block is clamped to the edge of the assembly hole, so that the prior wiper joint and the prior rocker arm form a specific matching structure, and further cause inconvenience in purchase and maintenance for consumers, the wiper joint of the utility model has the clamping space formed by the elastic pressing piece through the clamping end of each side plate, and can utilize the sliding part of the prior rocker arm to be used for pressing the elastic pressing piece against the second limiting block which slides relative to the connecting part, so that the elastic pressing piece generates elastic deformation towards the gap and is combined with the clamping space in a forced way without using a specific structure matched with the assembly hole of the connecting part, so that the wiper joint and the wiper arm with the wiper joint are applied to the rocker arms of the assembly holes with different sizes, and the maintenance cost can be saved, has the effects of improving the use convenience and the like.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the utility model.
