Three wiper connectors for adapting a U-shaped wiper arm, which are mainstream in the market at present, are respectively:

a conventional method comprises the following steps: patent publication No. CN1263835A discloses a wiper connector 1a, and with reference to fig. 1 and 2,

elastic locking points

5a and 5c are added to the front end portions of both side walls of the wiper connector 1a, and when the U-shaped wiper arm 100a is attached, the front end portion of the U-shaped wiper arm 100a is fitted into the

elastic locking points

5a and 5c of the wiper connector 1a, and the front end portion of the wiper connector 1a is tightly fitted to the wiper rod body 12a, thereby preventing elastic deformation of the

elastic locking points

5a and 5c and ensuring that the U-shaped wiper arm is not easily detached from the wiper connector 1 a.

The second conventional method comprises the following steps: patent numbers: ZL20061016549.2, referring to fig. 3 to 4, it is disclosed that the wiper connector 1b comprises at least an adaptor 42b, a connecting socket 40b and a safety lever 74b, wherein the front end portions of the two side walls of the adaptor 42b still have elastic locking points 60b, the front end portion 38b of the U-shaped wiper arm 22b is nested in the elastic locking points 60b, and a safety lever 74b is pivotally connected to one side wall of the front end portion of the adaptor 42b, so that when the safety lever 74b is engaged with the front end portion of the adaptor 42b, the elastic locking points 60b of the adaptor 42b are prevented from being deformed, and the U-shaped wiper arm 22b is prevented from being disengaged from the adaptor 42b, and when the safety lever 74b is opened, the elastic locking points 60b of the front end portion of the adaptor 42b are required to be opened by the U-shaped wiper arm 22b to be disengaged from the adaptor 42 b.

Three conventional methods are as follows: the subsequent bosch company developed a flip-type wiper, patent No.: 200580012836.2 referring to fig. 5, the wiper connector 1c is disclosed at least comprising an adapter 82c, a cover cap 26c, the front end of the two side walls of the adapter 82c likewise having a positioning ledge (resilient catch point) 76c, by means of which positioning ledge 76c the front end 12c of the U-shaped wiper arm 10c is inserted into the adapter 82c, in order to prevent the U-shaped wiper arm 10c from being detached from the adapter 82c, the deformation of the positioning ledge 76c is prevented by means of the snap-fit of the flap 50c of the cover cap 82c with the adapter 82c, and in this case a solution is provided in which the positioning ledge 76c can be omitted, namely by providing a limiting tab 64c on the inner side of the flap 50c, by means of which the limiting tab 64c bears directly against the outer contour of the hook-shaped end, namely independently of the resiliently deformable positioning ledge 76c, which can be provided or eliminated, the limit tab 64c is rigid and has no elasticity, otherwise if the limit tab 64c has elasticity, the limit tab 64c having elasticity cannot effectively prevent the problem that the U-shaped wiper arm 10c is released from the adapter 82c during wiping of the wiper.

Disclosure of Invention

The present invention is intended to solve the following technical problems arising from the background art:

the two side walls with elastic clamping points of the three wiper connectors 1a, 1b, 1c of the prior art have better elasticity in the disclosed technical solution, when the hook-shaped end of the U-shaped wiper arm is nested on the fixing surface of the wiper connector 1a, the

adaptor

42b, 82c, the specific definition of the fixing surface can refer to the definition (200580012836.2) of the three conventional patent documents, and the structure of the fixing surface defined by the present invention is consistent with the patent document, when no external additional member is applied to further restrict the outward elastic deformation of the two side walls with elastic clamping points, the anti-falling resistance force formed by the U-shaped wiper arm and the two side walls of the wiper connector 1a, the

adaptor

42b, 82c is less than 20N, usually about 10N, therefore, in order to ensure that the wiper connectors 1a, 1b, 1c can be stably connected with the U-shaped wiper arm, the external additional member is needed to restrict the outward elastic deformation of the two side walls with elastic clamping points, if one uses the wiper rod body 12a, two uses the safety tower buckle 74b, three uses the flip 50c, and uses the wiper connectors 1a and 1b and the U-shaped wiper arm, the U-shaped wiper arm is limited to move forwards relative to the wiper connector only by the elastic clamping point, once the elastic clamping point is aged or worn, the U-shaped wiper arm is easy to be separated from the wiper connectors 1a and 1 b; in addition, when the hook-shaped end part at the front end of the wiper arm is not standard, the elastic clamping point is forced to be outwards expanded, and the external accessory component applies inward holding force, so that the wiper connector and the wiper support cannot flexibly rotate, and the cleanliness of the windshield of the wiper is reduced.

The third conventional method not only discloses that the elastic clamping point 76c can be used for limiting the separation of the wiper connector 1c from the U-shaped wiper arm, but also discloses that the elastic clamping point 76c is not needed to be arranged, only a limit connecting piece 64c is added on the inner side surface of the flip cover 50c, and the limit connecting piece 64c is directly abutted against the front end of the U-shaped wiper arm, so that the wiper connector 1c and the U-shaped wiper arm are fixed, but because the limit connecting piece 64c is rigid and has no elasticity, if the processing precision of the adapted U-shaped wiper arm or the interface connecting piece 64c has errors, the hook-shaped end part of the U-shaped wiper arm can interfere with the limit connecting piece 64c, so that the U-shaped wiper arm cannot be smoothly installed on the wiper connector; if the wiper connector 1c is provided with the elastic contact point 76c and the limit contact piece 64c, following the solution disclosed in the technical document, the elastic contact point 76c and the limit contact piece 64c are required to act on the U-shaped wiper arm at the same time, so that there is a high requirement for the machining accuracy of the elastic contact point 76c and the limit contact piece 64c, otherwise, when the wiper arm is mounted, the wiper arm interferes with the elastic contact point 76c or the limit contact piece 64c due to the position accuracy error, and finally the mounting of the wiper connector 1c and the U-shaped wiper arm is inconvenient.

A first object of the present invention is to provide a wiper blade connector which is easy to install and is not easily separated from a U-shaped wiper arm.

A second object of the present invention is to provide a wiper connector which is more firmly mounted and has a wider adaptability.

A third object of the present invention is to provide a wiper using the wiper connector.

To achieve the first object of the present invention, there is disclosed a wiper blade connector adapted to a U-shaped wiper arm, the wiper connector at least comprises an adapter body, the adapter body comprises a pivot connection part and a fixing surface nested with the hook-shaped end part of the U-shaped wiper arm, the adapter body takes the pivot connection part as a rotation axis to swing up and down along the length direction of the adapter body, two longitudinal vertical side edges are formed at two sides of the fixed surface, the inner walls of the two side edges are respectively provided with a limit retaining edge at one end where the scraping arm is inserted from front to back, when the hook-shaped end part of the U-shaped scraping arm is nested on the fixed surface of the adapter body, the limit stop edge of the adapter body is abutted and contacted with the front end of the hook-shaped end part of the U-shaped scraping arm, meanwhile, the two side edges of the adapter body apply frictional resistance to the two side wings of the U-shaped scraping arm to ensure that when the hook-shaped end part of the U-shaped scraping arm is separated outwards from the fixing surface of the adapter body, the anti-drop resistance applied to the adapter body by the two side edges and the limiting blocking edge is more than or equal to 20N and less than or equal to 50N.

Although the structural characteristics of the adapter body are not different from those of the conventional adapter body, the adapter body is made of plastic by increasing the bending strength of two side edges of the adapter body, and the adapter body can be produced by selecting a material with a large elastic modulus or increasing the thickness of the two side edges of the adapter body under the condition of space allowance so as to realize that the two side edges of the adapter body have stronger bending strength, so that when the U-shaped scraping arm is separated from the fixing surface of the adapter body outwards, the anti-falling resistance applied to the two side edges and the limiting blocking edge of the adapter body is 20N-X-50N which is far higher than that of the conventional adapter body, the anti-falling resistance of the conventional adapter body is generally less than 20N and more is about 10N, and therefore, by using the adapter body structure of the invention, the stable connection of the U-shaped scraping arm and the adapter body can be realized without any external additional component.

In order to achieve the second object of the present invention, in addition to a wiper blade connector using the improved adapter as a U-shaped wiper arm, in order to further prevent the U-shaped wiper arm from being separated outwardly from the fixing surface of the adapter due to aging of the adapter or extreme weather conditions, a cover cap is additionally provided at the periphery of the adapter, the cover cap being composed of a base and an upper cover; the base is hollow up and down, the bottom of the base is provided with a fixing part which is fixedly connected with the windshield wiper support, and an upper cover which can be opened and closed is arranged on the base; gaps exist between the inner wall of the upper cover and at least two side edges of the adapter body in the area of the limit blocking edge, and the gaps have enough abdicating space, so that when the hook-shaped end parts of the U-shaped scraping arms are nested to the fixed surface of the adapter body, and the two side edges of the adapter body elastically deform outwards, the two side edges of the adapter body cannot generate any interference with the inner wall of the upper cover; and meanwhile, the inner wall of the upper cover is provided with blocking pieces at the front ends of the two limiting blocking edges of the adapter body at intervals, and the blocking pieces are used for secondarily limiting the U-shaped scraping arms to be separated from the fixing surface of the adapter body.
