As shown in fig. 2-1, a connecting block 12 is protruded above the base 11, a pair of hinge holes 13 symmetrically arranged along the pivot axis Y is formed on both side surfaces of the connecting block 12, an opening 131 is formed on the side of the hinge hole 13 opposite to the power end of the wiper arm, and the hinge hole 13 may be a through hole or a blind hole, preferably a blind hole, so that the structural strength of the whole connecting block 12 is better than that of the connecting block 13 which is a through hole; the both sides face of connecting block 12 forms the passageway 14 of stepping down of indent respectively in the vertical direction that is located the hinge hole 13 opening 131 front end, should step down passageway 14 and the bottom terminal surface of hinge hole 13 (blind hole) be located the coplanar, and every step down and form spacing step portion 15 between the front end of passageway 14 and the side of connecting block 12, this spacing step portion 15 is stop part A, spacing step portion does not necessarily set up on the passageway 14 of stepping down certainly, can additionally set up a spacing step portion (not shown) again at the both sides face of connecting block 12, but can lead to increasing the die sinking cost like this, consequently the spacing step portion 15 that the passageway 14 itself and the both sides face of connecting block 12 formed of using to step down is the optimum design.

The wiper blade joint 2a is used for fixing a wiper arm, and is swingably hinged in the hinge hole 13 of the wiper blade connecting base 1a, so that the wiper blade joint 2a has two common structural features with the wiper blade joints which are mainstream in the market at present: 1. the longitudinal body of the windshield wiper joint is provided with a connecting part which can be fixedly connected with the windshield wiper arm; 2. the wiper joint has a hinge shaft which can be mutually hinged with the hinge hole of the wiper connecting base. As shown in fig. 2-1 and 2-2, the longitudinal body of the wiper joint 2a includes a U-shaped groove member surrounded by a top wall 21 and two side walls 22, the two side walls 22 extend inward to form hinge shafts 221 symmetrically arranged, and the top wall 21 and/or the two side walls 22 are provided with connecting portions D for fixing the wiper arms, the specific structure of which can be directly referred to in the patent document CN2111223362U, in some wiper joints, the connecting portions D can be arranged at the bottom of the two side walls of the wiper joint to form bottom edges, and the connecting portions D formed by the bottom edges are fixed to the wiper arms, such as the wiper joint disclosed in CN210707317U, which is only a hinge hole shown in the drawing of the wiper joint of this embodiment, and only needs to be replaced by the hinge shaft, in fact, the connecting portions D of the wiper joint can be adjusted adaptively according to different wiper arms, and even for the same type of wiper arms, different manufacturers may design different connecting portions D to be fixed thereto, but the structure of the wiper joint connecting portion D is not a new point of the wiper joint 2a in terms of the present invention, and will not be described again.

In the wiper joint 2a disclosed in this embodiment, a first stop block 23 is respectively disposed on the inner side end surface of the longitudinal body and at a position corresponding to the receding channel 14, the first stop blocks 23 may be respectively fixed on the inner side end surfaces of the two side walls 22, or may also be fixed on the inner end of the top wall 21, in short, when the hinge shaft 221 of the wiper joint 2a is hinged to the hinge hole 13 of the wiper connecting base 1a, the first stop block 23 may be inserted into the receding channel 14 and be opposite to the position of the stop step portion 15 (blocking portion a) along the longitudinal direction of the connecting block 12.

Second embodiment

In order to further make the hinge shaft 221 of the wiper joint 2a less liable to be disengaged outwardly from the hinge hole 13 of the wiper connecting base 1a, a stopper mechanism C for stopping the entrance/exit of the hinge shaft 221 of the wiper joint 2a from/from the opening 131 of the hinge hole 13 is formed at the opening 131 of the hinge hole 13. In one embodiment of the stopper mechanism C, as shown in fig. 3-1 and 3-2, the shortest distance M between the openings 131 of the hinge holes 13 of the wiper connecting base 1b is at least smaller than the diameter N of the hinge shaft 221 of the wiper joint 2a for sliding into the hinge holes 13, and since the wiper joint 2a and the wiper connecting base 1b are made of plastic material, the hinge shaft 221 is inserted into the hinge holes 13 by pressing due to the elastic deformation margin of the material itself during the installation process, and once the hinge shaft 221 is installed in place, the hinge shaft 221 is not easily slid out of the hinge holes 13. Of course, in the prior art disclosed in the related art, the hinge shaft is notched as disclosed in the related art CN109159760A, by adjusting the insertion angle of the hinge shaft, the hinge shaft can be slid into the hinge hole without being pressed, and then the angle of the hinge shaft is rotated so that it is not easily slid out from the hinge hole, and this type of hinge shaft is also applicable to the present invention.

Third embodiment

In another embodiment of the stopping mechanism C, as shown in fig. 4-1 to 4-3, a first hollow portion 33 is disposed below the abdicating channel 14 in the connecting block 12 of the wiper connecting base 1C, a stopping sheet 3 is a sheet-shaped body with elastic deformation, a fixed end 31 thereof is fixedly disposed at one side of the abdicating channel 14 away from the opening 131 of the hinge hole 13, a free end 32 thereof is disposed in the first hollow portion 33 and extends to the opening 131 of the hinge hole 13 in an arc-inward concave manner from bottom to top, and the height thereof does not exceed the height of the center of the circle of the hinge hole 13, and the first hollow portion 33 has an abdicating space for allowing the free end 32 of the stopping sheet 3 to elastically deform downward; the blocking piece 3 has at least two operating positions, when the blocking piece 3 is in the first operating position, it is in a stable elastic return state, its free end 32 is located at the opening 131 of the hinge hole 13, for limiting the outward disengagement of the hinge shaft 221 of the wiper joint 2a from the opening 131 of the hinge hole 13; when the blocking piece 3 is at the second working position, the free end 32 is abutted against the hinge shaft 221 of the wiper joint 2a, the blocking piece 3 is driven to shift downwards by the hinge shaft 221, the free end 32 of the blocking piece 3 is driven to be away from the opening 131 of the hinge hole 13, and the hinge shaft 221 of the wiper joint 2a can enter/exit from the opening 131 of the hinge hole 13. In fact, this is only one of the setting modes of the blocking piece 3, since the blocking piece 3 is elastically deformed downward when being stressed, the first hollow part 33 needs to be added downward, and if the fixed end of the blocking piece 3 is set on the top of the connecting block 12, and the blocking piece 3 is elastically deformed upward when being stressed, the setting of the first hollow part 33 can be omitted (not shown).

The description of the method for disassembling/assembling the wiper joint 2a and the wiper connecting bases 1a, 1b, 1c,

as shown in fig. 3-2 to 3-4, which disclose the installation of the wiper joint 2a and the wiper connecting base 1b (the second embodiment of the first series), it is preferred to adjust the orientation of the front end of the wiper joint 2a to the side opposite to the opening 131 of the hinge hole 13 of the connecting block 12 of the wiper connecting base 1b, i.e., the front end of the wiper joint 2a is located at the front end of the opening 131 of the hinge hole 13 of the connecting block 12, and then to position the hinge shaft 221 opposite to the relief passage 14 of the wiper connecting base 1b while tilting up the front end of the wiper joint 2a until the angle β between the longitudinal axis R of the wiper joint 2a and the wiper connecting base 1b in the X-axis direction is larger than or equal to the minimum mounting and dismounting angle α (as shown in fig. 3-2), which can ensure that when the two side walls 22 of the wiper joint 2a nest the connecting block 12 into its inner cavity, the first limiting block 23 does not abut against and interfere with the top of the limiting stepped part 15, so that the hinge shaft 221 of the wiper joint 2a can sequentially slide into the hinge hole 13 through the abdicating channel 14 of the connecting block 12 and the opening 131 of the hinge hole 13; then, the front end of the wiper joint 2a is pressed down, so that the included angle β between the longitudinal axis R of the wiper joint 2a and the wiper connecting base 1b along the X-axis direction is less than the minimum assembling and disassembling angle α (as shown in fig. 3-3 and 3-4), when the hinge shaft 221 of the wiper joint 2a is separated from the opening 131 of the hinge hole 13 of the connecting block 12, the first limiting block 23 will generate abutting interference with the limiting step 15, thereby avoiding the wiper joint 2a and the wiper connecting base 1b from being separated from each other, and completing the installation of the wiper joint 2a and the wiper connecting base 1 b; when the wiper needs to be detached, the wiper joint 2a and the wiper connecting base 1b can be detached only by reverse operation. It should be noted that, when the wiper joint 2a is in the operable state, and the front end of the wiper joint 2a is necessarily swung downward relative to the wiper joint in the installation insertion state, because the wiper joint 2a is fixedly connected with the wiper arm, when the wiper joint 2a with the wiper arm is hinged with the wiper connecting base 1b (not shown in the figure), the wiper joint 2a is always pressed by the wiper arm, and the pressing force drives the hinged shaft 221 of the wiper joint 2a to rotate counterclockwise (i.e. the front end of the wiper joint 2a swings downward), so that the wiper joint 2a and the wiper connecting base 1b are in a relatively stable balanced state, generally, the longitudinal axis R of the wiper joint 2a and the wiper connecting base 1b are parallel to each other in the X-axis direction (the top surface of the base 11) or the front end of the wiper joint 2a is tilted downward toward the base 11 of the wiper connecting base 1b, meanwhile, the downward pressing force of the wiper arm is transmitted to the wiper connecting base 1b through the wiper joint 2a and finally transmitted to the wiper rubber strip of the wiper support assembly, so that the wiper rubber strip can be always attached to the surface of the windshield glass, as shown in fig. 3-4, in this state, even if the windshield glass is an arc surface, during the wiping process of the wiper, an included angle beta between the longitudinal axis R of the wiper joint 2a and the wiper connecting base 1b along the X-axis direction can slightly swing up and down, an included angle beta between the longitudinal axis R of the wiper joint 2a and the wiper connecting base 1b along the X-axis direction is always smaller than or equal to 0 degrees, the positive value is based on the wiper connecting base 1b along the X-axis direction, the clockwise rotation is a positive value, the counterclockwise rotation is a negative value, therefore, the minimum assembling and disassembling angle alpha can be set to be larger than 0 degrees, namely when the longitudinal axis R of the wiper joint 2a and the wiper connecting base 1b are in a parallel state along the X-axis direction, the first limit block 23 of the wiper joint 2a interferes with the limit step 15 of the wiper connecting base 1b, so that the wiper joint 2a cannot be separated from the wiper connecting base 1 b; moreover, in the wiping process (working state) of the wiper, the relative movement direction between the hinge shaft 221 of the wiper joint 2a and the hinge hole 13 of the wiper connecting base 1b is opposite to the opening 131 direction of the hinge hole 13, so that the connection between the wiper joint 2a and the wiper connecting base 1b is further ensured, and the mutual separation of the two is avoided. Meanwhile, since the windshield wiper connecting bases 1b and 1C are provided with the stopping mechanisms C with different structural designs in the embodiments disclosed, as mentioned above, as shown in fig. 4-2 to 4-3, the risk of the hinge shaft 221 of the wiper joint 2a being disengaged from the opening 131 of the hinge hole 13 of the wiper connecting base 1b, 1c is further reduced, especially when the vehicle is in a state of repairing or washing the windshield, the wiper joint 2a and its wiper connecting bases 1b, 1c are erected together with the wiper arm, suspended from the upper surface of the windshield glass, even if the angle β between the longitudinal axis R of the wiper joint 2a and the wiper connecting base 1b, 1c in the X-axis direction is larger than the minimum attachment/detachment angle α, the hinge shaft 221 of the wiper joint 2a cannot be disengaged from the opening 131 of the hinge hole 13 of the wiper connecting base 1b, 1 c.

Preferably, for better safety redundancy, the minimum mounting and dismounting angle α is more than or equal to 3 °, and the minimum mounting and dismounting angle α can be set to be more than or equal to 3 ° and less than or equal to 10 °, that is, the wiper joint 1a can be detached from the opening of the hinge hole 13 of the wiper joint base 1a, 1b, 1c only when the front end of the wiper joint 2a swings upwards within the interval, so that the included angle β between the longitudinal axis R of the wiper joint 2a and the wiper joint base 1a, 1b, 1c along the X-axis direction is more than or equal to α.

In a more preferable design, in order to facilitate the user to adjust the insertion and installation angles between the wiper fitting 2a and the wiper connecting bases 1a, 1b, and 1c, so that the wiper fitting 2a can be installed/detached on/from the wiper connecting bases 1a, 1b, and 1c more conveniently, as shown in fig. 4-2 for example, a first inclined plane 121 and a second inclined plane 122 are respectively arranged at the top of the connecting block 12 of the wiper connecting base 1c from front to back, and the first inclined plane 121 is located at the front end of the hinge hole 13 and is gradually higher from front to back; the second inclined plane 122 is located at the rear end of the hinge hole 13, and the height of the second inclined plane is gradually reduced from front to back; an arc-shaped protrusion 123 is additionally arranged at the top of the connecting block 12 between the first inclined surface 121 and the second inclined surface 122, and the arc-shaped protrusion 123 is positioned above the hinge hole 13 and at the high position of the top of the connecting block 12; the top wall 21 of the wiper joint 2a, 2b is provided with a second hollow portion 211 at a position corresponding to the arc-shaped protrusion 123, so that when a user mounts the wiper joint 2a to the wiper connecting base 1c, the user only needs to make the wiper joint 2a and the first stopper 23 opposite to the yielding channel 14, and then the two side walls 22 of the wiper joint 2a are put into the connecting block 12 from top to bottom, so that the inner side end surface of the top wall 21 of the wiper joint 2a and the second inclined surface 122 of the connecting block 12 abut against each other, the minimum included angle γ between the second inclined surface 122 of the connecting block 12 and the base 11 along the X-axis direction is not less than the assembling and disassembling angle α, thereby ensuring that the front end of the wiper joint 2a is tilted upward, the hinge shaft 221 of the wiper joint 2a slides into the hinge hole 13 of the connecting block 12, the first stopper 23 does not interfere with the limiting step portion 15, and the wiper joint 2a and the wiper connecting base 1a, b, c, 1b and 1 c; when the wiper joint 2a needs to be detached from the wiper connecting base 1a, 1b, 1c, only the reverse operation is needed, the inner end of the top wall 21 of the wiper joint 2a abuts against the second inclined surface 122 of the wiper connecting base 1b, then the wiper joint 2a is pushed out from the direction of the opening 131 of the hinge hole 13 of the wiper connecting base 1b with force, the hinge shaft 221 of the wiper joint 2a abuts against the blocking piece 3, so that the downward position of the blocking piece is deviated, the access passage of the opening 131 of the hinge hole 13a is opened, and the wiper joint 2a can be detached from the wiper connecting base 1 b. Compared with the traditional windshield wiper connecting base, the windshield wiper connecting base is often only provided with the hinge holes, the hinge shafts of the windshield wiper connector are nested in the hinge holes through elastic deformation of the two side walls of the windshield wiper connector, once the windshield wiper connector is required to be detached from the windshield wiper connecting base, the windshield wiper connector is often required to be detached violently, and the side walls of the windshield wiper connector are detached in a prying way by using a screwdriver, so that the detachment and the installation are very inconvenient, the windshield wiper connector 2a matched with the windshield wiper connecting base 1b can be quite convenient to detach/install, and once the windshield wiper connector is installed, the windshield wiper connector 2a is quite firm and is not easy to detach from the windshield wiper connecting base 1 b. Meanwhile, the first inclined surface 121 of the connecting block 12 is also arranged to provide an abdicating space for the front end of the wiper joint 2a to swing downwards relative to the wiper connecting base 1c, and the first inclined surface 121 and the second inclined surface 122 are also convenient for controlling the up-and-down swing angle of the wiper joint 2a relative to the wiper connecting base 1b by using the hinge shaft 221 as a swing fulcrum.

A second series: the blocking part is arranged at the top of the connecting block of the windshield wiper connecting base

The most obvious difference between the windshield wiper connecting bases 1d, 1e and 1f disclosed by the series and the first series of windshield wiper connecting bases 1a, 1b and 1c lies in that the limiting step part formed by the abdicating channel 14 and the two side faces of the connecting block 12 is not utilized as a blocking part, but a limiting sunk groove 4 is formed at the top of the connecting block 12 and at the front end of the hinge hole 13 in a unique way, the limiting sunk groove 4 is provided with an accommodating space extending along the longitudinal direction of the connecting block 12, and the limiting sunk groove 4 is the blocking part A.

The series of wiper joints 2B at least comprises a top wall 21 and two side walls 22 enclosing to form a U-shaped groove member, the two side walls 22 have inward extending hinge shafts 221 which are symmetrically arranged, the inner end of the top wall 21 extends downwards relative to the position of the limit sunken groove 4 to form a second limit block 24, the second limit block 24 is positioned at the front end of the hinge shafts 221, the second limit block 24 can be inserted into the limit sunken groove 4 in a clearance fit manner, and the second limit block 24 is a limit part B.

More specifically, as shown in fig. 5, in the second series of the first embodiments, the limit sunken groove 4 of the wiper connecting base 1d is a rectangular sunken groove 41; the second limit block 24 of the wiper joint 2b is a rectangular block 24a, and the length G of the rectangular block 24a along the longitudinal direction of the connecting block 12 is less than the length H of the limit sinking groove 4 along the longitudinal direction of the connecting block 12.

On the basis of this embodiment, as shown in fig. 6, in the second series of second embodiments, the limit sunken groove 4 of the wiper connecting base 1e further comprises an axial sunken groove 42 extending along the longitudinal direction thereof at the rear end of the rectangular sunken groove 41, and the horizontal cross sections of the rectangular sunken groove 41 and the axial sunken groove 42 are in a convex shape; the second limiting block 24 of the wiper joint 2b further comprises an axial block 24b extending from the front end or the rear end of the rectangular block 24a to form a convex block, the rectangular block 24a and the axial block 24b are correspondingly inserted into the rectangular sinking groove 41 and the axial sinking groove 42, the axial sinking groove 42 is additionally arranged on the wiper joint base 1e, the axial block 24b is additionally arranged on the wiper joint base 2b to guide and limit the axial block 24b, and the wiper joint 2b is less prone to relative displacement along the width direction with the wiper joint base 1e after the wiper joint 2b and the wiper joint base 1e are installed in place.

In a more optimized design, as shown in fig. 6, when the axial block 24b is located at the rear end of the rectangular block 24a, the front end of the rectangular sinking groove 41 forms a sinking plane 411, and the bottom of the axial block 24b and the side far away from the rectangular block 24a are further provided with an abdicating inclined plane 241b, so that the minimum loading and unloading angle α formed between the longitudinal axis R of the wiper joint 2b and the wiper joint base 1e along the X-axis direction can be reduced, and the minimum included angle γ between the second inclined plane 122 of the joint block 12 and the base 11 along the X-axis direction can be reduced, i.e. assuming the design without the sinking plane 411 and the abdicating inclined plane 241b, the minimum loading and unloading angle α and the minimum included angle γ can only be set to 6 °, but with the sinking plane 411 and the abdicating inclined plane 241b, the minimum loading and unloading angle α and the minimum included angle can be set to 5 °, and the above example is only illustrating the design with/without the sinking plane 411 and the abdicating inclined plane 241b, the minimum loading angle α and the minimum angle γ are illustrated as only one of the reference values. Due to the reduction of the minimum loading and unloading angle α, the angle of the minimum included angle γ of the second inclined surface 122 is reduced, so that the two side surfaces of the connecting block 12 of the wiper connecting base 1e have a sufficiently large abutting contact area at the rear end of the hinge hole 13, thereby avoiding the problem that the hinged connection between the wiper joint and the wiper connecting base is not firm due to the excessively large inclined surface at the top of the connecting block (i.e. the second inclined surface of the present invention) as disclosed in the prior art (CN 109159760A).

As shown in FIG. 7-2, the method of removing/fitting the series of wiper joint 2b from/into the wiper connecting bases 1d, 1e, 1f substantially coincides with the method of removing/fitting the first series of wiper joint 2a from/into the wiper connecting bases 1a, 1b, 1c only when the angle beta between the longitudinal axis R of the wiper joint 2b and the wiper connecting bases 1d, 1e, 1f in the X-axis direction is smaller than the minimum attaching/detaching angle alpha, and when the hinge shaft 221 of the wiper joint 2b is moved in the direction of disengaging from the opening 131 of the hinge hole 13 of the joint block 12, the second stopper 24 of the wiper joint 2b comes into abutting interference with the front end inner wall of the stopper depression 4 (rectangular depression 41) to thereby restrict the wiper joint 2b from disengaging from the wiper connecting bases 1d, 1e, 1f from each other, and the space at the opening 131 of the hinge hole 13 disclosed in the wiper connecting base 1e is smaller than the design of the outer diameter of the wiper joint 2b (as shown in FIG. 6) The design (as shown in fig. 7-1) of the second series of second embodiments, or the design of adding the blocking piece 3 at the opening 131 of the hinge hole 13 disclosed by the wiper connecting base 1f [ the second series of third embodiments ], is consistent with the technical solutions and effects disclosed by the first series of wiper connecting bases 1b and 1c, and will not be described again.

Meanwhile, the invention also discloses a windshield wiper, which is matched with any series of windshield wiper connecting components (comprising a windshield wiper joint and a windshield wiper connecting base), and the windshield wiper connecting components with the structure are convenient to disassemble/assemble with the windshield wiper connecting base.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
