Detailed Description

First of all, it should be noted that the structure, composition, features and advantages of the wiper blade adapter, the wiper blade and the wiper according to the present invention, etc. will be described below by way of example, however, all the descriptions should not be construed to form any limitation to the present invention.

In this document, the technical term "connected" means that one component is directly connected to another component and/or indirectly connected to another component, the technical terms "first", "second" are used for distinguishing expression purposes only and are not intended to indicate their order or relative importance, and the technical terms "upper", "lower", "right", "left", "front", "rear", "inner", "outer", derivatives thereof and the like should be taken in connection with the orientation in the drawings, and the present invention may take a variety of alternative orientations unless explicitly stated otherwise.

In fig. 1, a basic three-dimensional structure of an exemplary embodiment of a wiper blade adapter is shown, which is intended for mounting to a wiper strip of a wiper blade and which can be made of a rigid material, for example metal. In this example, the wiper blade adapter 10 can comprise a body 11 and two side parts, namely a first side part 12 and a second side part 13, which are arranged opposite one another and between which a shaft 14 is arranged, around which shaft 14 one end of the wiper arm 40 can be mounted in some applications, as is shown by way of example in fig. 3, 9 to 11, respectively, and the respective ends of the U-shaped hook-type wiper arm 41 in fig. 3, the top-locking wiper arm 43 in fig. 9 and 10, the bar-type top-locking wiper arm 44 in fig. 11 can be mounted around the shaft 14, respectively.

In practice, a connector 30 made of, for example, a plastic material can be used as an intermediate connecting part, which can have various configurations for connecting the wiper arm to the wiper blade adapter 10, so that any suitable structure can be provided on the connector 30, depending on the application, for example a structure in which the shaft 14 is sheathed after assembly, and the wiper arm described above is then fitted over this structure, instead of directly over the shaft 14. It should be noted that, of course, the structural configuration, assembly connection, etc. of the wiper arm, the connector, the wiper strip, and possibly other components (such as the retaining spring, the locking component, etc.) are not the main points of the present invention, and therefore, will not be discussed in further detail herein.

As shown in fig. 1, a body 11 constitutes a part of the wiper blade adapter 10, and a fitting portion may be provided on the body 11 so that the body 11 can be fitted in place therethrough in the longitudinal direction of the wiper strip 21 of the wiper blade 20. The mounting portion may take any suitable form to perform the functions described herein, depending on the particular application.

By way of example only, referring to fig. 1 to 3 in combination, in the given example, the fitting portions may be disposed at both ends of the body 11, but may be disposed symmetrically at both front and rear ends, which may help to fix the wiper blade adapter to the wiper blade more stably and reliably. For the fitting portion provided at each end, there may be included, for example, an opening 110 and two side portions 111,112 extending downward from the body 11, which will serve as two stopper portions for restricting the displacement movement of the body 11 on the wiper strip 21, respectively.

Specifically, for example, as shown in fig. 2, a fitting structure 22 for fitting positioning with the wiper blade adapter may be provided on the wiper strip 21, such a fitting structure 22 may have any suitable structural feature such as a protruding portion 222, and when the wiper blade adapter 10 is mounted on the wiper strip 21, the opening 110 may be snap-fitted into the protruding portion 22, so that at least the body 11 can be restricted from moving in the longitudinal direction of the wiper strip 21, i.e., it is thereby also possible to avoid or reduce undesired movement of the body 11 in the transverse or other direction of the wiper strip 21.

Further, as shown in fig. 1 and 2 again, when the wiper blade adapter 10 is assembled with the wiper strip 21, the two side portions 111,112 extending downward from the body 11 are respectively received in the two receiving portions 221,222 on the above-described assembling structure 22, so that it is possible to at least restrict the body 11 from moving in the transverse direction of the wiper strip 21, i.e., thereby to avoid or reduce the body 11 from undesirably moving in the longitudinal direction or other directions of the wiper strip 21.

Referring back to fig. 1, fitting portions may be provided on the first side portion 12 and the second side portion 13 in the wiper blade adapter 10 so as to be used for fitting connection with two or more kinds of wiper arms 40 having different configurations and connectors 30 thereof, and various types of wipers may be formed therefrom, for example, five types of wipers 100, 200, 300, 400, and 500 formed after assembly are exemplarily illustrated in fig. 4 to 12, respectively, in which a U-shaped hook-type wiper arm 41, a side-locking-type wiper arm 42, a top-locking-type wiper arm 43, a plug-type bar top-locking-type wiper arm 44, and a side-pin-type wiper arm 45 are used in a matching manner. In this way, it is possible to easily match more types of wiper arms, connectors, and the like using the same wiper blade adapter as much as possible, which not only contributes to reduction in cost of the wiper blade adapter and the wiper by implementing mass production, but also facilitates operations such as assembly, maintenance, replacement, and the like.

In alternative cases, the mating portion described above may be configured as a hole, slot, or other suitable structure. For example, in the example of fig. 1, the fitting portion on the first side portion 12 is configured to have two holes 121,121 'and a groove 122, the two holes 121,121' can be respectively disposed on the left and right sides of the shaft 14 and can have different sizes, so that a portion (such as a fixing pin structure, etc.) of some different types of wiper arms can be selectively inserted and positioned in one of the holes, such as shown in fig. 6 to 8, for example, the assembling operation can be completed by first inserting the fixing pin 421 on the laterally locked wiper arm 42 into the holes 121, 131 of the wiper blade adapter 10, then rotating the laterally locked wiper arm 42, and assembling its lateral locking portion 422 onto the connector 30 which is fitted onto the wiper blade adapter 10; as another example, this is shown in fig. 12 by inserting lateral locking portions on the side-pinned wiper arm 45 into holes 121', 131' of the wiper blade adapter 10 and by forming a fitting connection by means of corresponding locking elements 451 provided in the connector 30, which locking elements 451, for example, can be locked during fitting by means of an elastic, self-sliding into locking means of the side-pinned wiper arm 45.

A groove 122 is provided below the two bores 121 and the shaft 14, which can optionally be closed at one end and open at the other end, for a part of some type of wiper arm (e.g. a top-locking wiper arm or the like) to be inserted into the groove from the open end, as is exemplarily shown in fig. 10, by sliding the top-locking wiper arm 43 and inserting its bottom hook into the groove 122 of the wiper blade adapter 10, and then locking is formed by a locking member 431 on top of the top-locking wiper arm 43, which locking member 431 can be automatically slid into a locking mechanism of the top-locking wiper arm 43 by elasticity, for example, upon assembly. In the assembled configuration, the connector 30 is fitted to the wiper blade adapter 10 and can cover at least a part of the side portion of the wiper blade adapter 10.

The above description of the mating portion on the first side portion 12 is omitted since the same or similar applies to the two holes 131,131' and the slot 132 on the second side portion 13, and the holes 131,131' and the slot 132 therein may have the same size as the corresponding holes 121,121' and the slot 122 on the first side portion 12, respectively.

Furthermore, as an alternative, an interference portion may be provided on the wiper blade adapter 10, for example, on the first side portion 12 and/or the second side portion 13, which interference portion is to be used to correspondingly cooperate with a fool-proof structure (such as a hole, a groove, a bump, etc.) on the connector 30, so as to provide a fool-proof fitting function, i.e., thereby defining that both the connector 30 and the wiper blade adapter 10 can be fitted together only in a predetermined direction, and that it is impossible to fit them together if any other non-predetermined direction is adopted, so that it is possible to avoid that the wiper blade adapter is mounted in an incorrect direction on a production line or in use, which will contribute to an improvement in the fitting efficiency, ensuring that a reliable mounting quality is obtained.

Illustratively, the first surface 120 on the first side portion 12 and the second surface 130 on the second side portion 13 may be configured to have different configurations so that the function of the interference portion described above may be provided thereby. For example, as shown in fig. 1, the top of the first surface 120 may be configured to be substantially "W" shaped such that it has two lower inflection points 123, between which lower inflection points 123 there is a recess of lower height; meanwhile, the top of the second surface 130 may be configured to have an upper inflection point 133 having a height in a vertical direction greater than that of the recess. When the connector 30 and the wiper blade adapter 10 are assembled in the desired predetermined orientation, the corresponding fool-proofing structures on the connector 30 will properly contact the lower inflection point 123 and the upper inflection point 133 without interference therebetween, so that they can be properly mounted in place; in contrast, if the proper predetermined orientation is not achieved, the corresponding fool-proofing structure on the connector 30 will first contact the upper inflection point 133 to interfere therewith, thereby preventing erroneous assembly.

In addition, as an alternative, it may be considered to provide a marking portion for indicating the above-mentioned predetermined direction on any one or more of the body 11, the first side portion 12, the second side portion 13, and the connector 30 of the wiper blade adapter 10. For example, as shown in fig. 2, markings 15 and 31, which are indicated by arrows, may be provided on the housing of the body 11 and the connector 30, respectively, so that an operator can clearly understand and use a correct predetermined direction to complete the fitting operation between the wiper blade adapter 10 and the connector 30.

It should be understood that those skilled in the art can implement the body and the fitting portion thereof, the wiper strip and the fitting structure thereof, the connector and the fool-proof structure thereof, etc. of the wiper blade adapter exemplarily discussed above in a variety of possible structural arrangements without departing from the spirit of the present invention, and the present wiper blade adapter will not necessarily be limited to the specific structure discussed herein. For example, although two side portions are provided at the same time in the foregoing wiper blade adapter example, only one side portion may be provided in some embodiments, or three or more side portions may be provided, which may be independent and spaced apart from each other, for example, the above-described first side portion (or second side portion) may be modified into two or more side portions, which may be arranged in parallel, or may be arranged spaced apart from each other. As another example, the configuration, arrangement position, number, etc. of the holes, grooves, etc. in the wiper blade adapter all allow for a flexible arrangement, for example, the holes in the wiper blade adapter can be arranged to have exactly the same or different dimensions, or only a number of holes therein can have the same dimensions.

In addition, the present invention also provides a wiper blade, which comprises the wiper blade adapter designed and provided according to the present invention, and thus can have the characteristics and advantages of the present invention over the prior art.

In addition, the present invention also provides a wiper, which has been exemplarily described above in connection with the embodiments of fig. 5 to 12. It should be noted that the wiper according to the present invention should not be limited to the above embodiments, and in particular, should not be limited to the wiper arm, for example, a U-shaped hook type wiper arm, a side locking type wiper arm, a top locking type wiper arm, a bar insertion type top locking type wiper arm, a side pin type wiper arm, etc., and the connector thereof may have various different configurations (see fig. 4, 9, 11, 12, etc.), and some of the configurations may be adapted to various types of wiper arms at the same time (see fig. 4, 6, etc.).

In a specific application, a corresponding wiper blade adapter and a connector, a wiper blade or the like adapted thereto can be designed and manufactured according to the subject matter of the invention, so that more types of wiper arms can be adapted simultaneously using the same wiper blade adapter in order to meet the various possible practical requirements. By using the same wiper blade adapter, it is possible to connect a plurality of types of wiper arms, connectors, and wiper blades in a matched manner to form a plurality of types of wipers, the wiper arms being driven by power supplied from, for example, a motor or the like to carry a wiper strip to wipe a wiping object (e.g., a windshield or the like mounted on various vehicles, ships, or the like) so as to remove, for example, rainwater, snow, mist, dirt, or the like.

The wiper blade adapter, wiper blade and wiper according to the present invention have been described in detail above by way of examples, which are provided only for illustrating the principles of the present invention and its embodiments, not for limiting the present invention, and those skilled in the art can make various modifications and improvements without departing from the spirit and scope of the present invention. Accordingly, all equivalent embodiments are intended to fall within the scope of the present invention and are defined by the various claims of the present invention.
