The wiper connecting base 1a disclosed by the invention can be adapted to a large number of conventional wiper joints 2a with hinged shafts on both side walls, the wiper joint 2a is used as a second component of a wiper connecting component for connecting a wiper bracket component and a wiper arm, the wiper joint 2a is mainly used for fixedly connecting the wiper arm, and as shown in fig. 3-2, the wiper joint 2a has two common structural characteristics with the wiper joints which are mainstream in the market at present: 1. the 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. Specifically, the 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 a connecting portion F for fixing the wiper arm is provided on the top wall 21 and/or the two side walls 22, the specific structure of the connecting portion F can be directly referred to the patent document CN2111223362U, in a part of the wiper joint, the connecting portion F can be arranged at the bottom of the two side walls of the wiper joint to form a bottom edge, the connecting portion F formed by the bottom edge is fixed to the wiper arm, such as the wiper joint disclosed in CN210707317U, the figure of the wiper joint of this embodiment is the hinge hole, and the hinge hole needs to be replaced by the hinge shaft, in fact, the connecting portion F of the wiper joint can be adjusted adaptively according to different wiper arms, and even for the same type of wiper arms, different manufacturers can design different connecting portions F to be fixed thereto, however, in the present invention, the structure of the wiper joint connecting portion F is not the innovative point of the wiper joint 2a, and will not be described again, and in the present embodiment, the wiper joint 2a uses the hinge shaft 221 to overcome the blocking of the blocking piece 3 disposed at the opening 131 of the hinge through hole 13b, and the blocking piece 3 is driven to be elastically deformed downward to be positionally deviated, so that the hinge shaft 221 is nested in the hinge through hole 13b of the wiper joint base 1a, and the wiper joint 2a is swingably hinged in the hinge through hole 13b of the wiper joint base 1a, and since the wiper is in the wiping process (working state), the relative movement direction between the hinge shaft 221 of the wiper joint 2a and the hinge through hole 13b of the wiper joint base 1a is opposite to the opening 131 of the hinge through hole 13, and the force receiving portion thereof is not at the position of the blocking piece 3, so that the blocking piece 3 is not substantially subjected to force, only when the vehicle is in a state of maintaining or cleaning the windshield glass, the wiper joint 2a and the wiper connecting base 1a thereof are erected together with the wiper arm, suspended on the upper surface of the windshield glass, the hinge shaft 221 of the wiper joint 2a is disengaged outwardly toward the opening 131 of the hinge through hole 13b, at this time, the hinge shaft 221 of the wiper joint 2a is restricted from disengaging from the hinge through hole 13b of the wiper connecting base 1a due to the abutment of the blocking piece 3, thereby achieving stable mounting of the two; when the wiper joint 2a needs to be replaced, the front end of the wiper joint 2a is tilted up, so that the hinged shaft of the wiper joint 2a presses the blocking piece 3, the access passage of the open end 131 of the hinged through hole 13b is opened, and the wiper joint 2a can be separated from the wiper connecting base 1 a. It should be noted that, 1, the barrier sheet 3 has certain requirements on the elastic modulus during the design, that is, elastic deformation occurs only under certain acting force condition; 2. the stiff end 31 of blocking piece 3 sets up in the horizontal X direction rather than perpendicular Z direction that blocks 3 free end 32 atress direction, makes the free end 32 that blocks piece 3 more difficult emergence elastic deformation under the prerequisite of same effort, assumes that the atress of the free end 32 of blocking piece 3 along horizontal direction (X direction) needs 10N at least just can order about its elastic deformation promptly, but if the effort shifts to the perpendicular face (Z direction) of free end 32, only need 5N just can order about the free end 32 that blocks piece 3 and take place elastic deformation.
Second embodiment:
referring to fig. 3-1, the invention discloses a windshield wiper connecting base 1b, wherein a connecting block 12 is convexly arranged above a base 11, the connecting block 12 forms a pair of hinge holes 13a (blind hole arrangement) symmetrically arranged along a pivot axis Y, the hinge holes 13a form an opening 131 on the side opposite to the power end of the windshield wiper arm, and the hinge holes 13a adopt blind hole design, so that the overall strength of the connecting block 12 can be improved; two side faces of the connecting block 12 form an inwards concave abdicating channel 14 from top to bottom at the insertion end of the opening 131 of the hinge hole 13a, the abdicating channel 14 and the bottom end face of the hinge hole 13a (blind hole) are positioned on the same plane, a first limiting step part 15a is respectively formed at the abdicating channel 14 and the front end of the two side faces of the connecting block 12, and a first hollow part 33 is arranged below the abdicating channel 14; the blocking sheet 3 is a sheet-shaped body with elastic deformation, the fixed end 31 of the blocking sheet is arranged on one side of the abdicating channel 14 far away from the opening 131 of the hinge hole 13a, the free end 32 of the blocking sheet is inwards concave in an arc from bottom to top and is arranged in the first hollow part 33, the first hollow part 33 is provided with an abdicating space for the free end 32 of the blocking sheet 3 to elastically deform downwards, the free end 32 of the blocking sheet 3 is positioned at the opening 131 of the hinge hole 13a when the elastic deformation state is not generated, and the height of the free end does not exceed the height of the circle center of the hinge hole 13a, so that the blocking sheet 3 can be driven to downwards generate position deviation when a hinge shaft of a subsequent windshield wiper joint is abutted and contacted with the hinge shaft; in a more optimized design, the top of the connecting block 12 is respectively provided with a first inclined surface 121 and a second inclined surface 122 from front to back, the first inclined surface 121 is positioned at the front end of the hinge hole 13a, and the height of the first inclined surface is gradually increased from front to back; the second inclined plane 122 is located at the rear end of the hinge hole 13a, and the height thereof is gradually reduced from front to rear; 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 located above the hinge hole 13a and at a high position of the top of the connecting block 12.
The wiper connecting base 1b disclosed in the present invention can also be adapted to a conventional wiper joint 2a (only one of them is representative) having a hinge shaft 221, and the assembly manner between the two is not significantly different from that of the first embodiment, as shown in fig. 3-2 and 3-3, the hinge shaft 221 of the two side walls 22 of the wiper joint 2a presses the blocking piece 3 down through the relief channel 14 of the two side surfaces of the connecting block 12, and drives the free end 32 of the blocking piece 3 to be elastically deformed downwards and to be positionally displaced, so that the hinge shaft 221 of the wiper joint 2a smoothly slides into the hinge hole 13a, which is different from that of the first embodiment: 1. the hinge hole 13a is a blind hole, so that the overall strength of the connecting block 12 is improved; 2. the front end of the connecting block 12 has no sinking portion, so that both side surfaces of the connecting block 12 can provide a larger abutting area for both side walls 22 of the wiper joint 2a, ensuring that the wiper joint 2a is not easily deflected in the width direction with respect to the wiper connecting base 1 b; 3. a first inclined plane 121 and a second inclined plane 122 are additionally arranged on the top of the connecting block 12, thereby being used for controlling the front-back swing angle of the wiper joint 2a relative to the wiper connecting base 1b by taking the hinge shaft 221 as a rotation axis center; 4. while the two side surfaces of the connecting block 12 are provided with the receding channels 14 which are recessed inwards, a first limiting step part 15a is formed between the front end of the receding channel 14 and the two side surfaces of the connecting block 12, the first limit step part 15a is a blocking part A, and because the first limit step part 15a is additionally arranged, therefore, the conventional wiper blade joint 2a may be provided with a first stopper 23 at the inner end surfaces of the two side walls 22, respectively, at a position opposite to the escape passage 14, as shown in fig. 3 to 4, the first stoppers 23 may be fixedly provided at the inner end surfaces of the two side walls 22, respectively, or at the inner end of the top wall 21, and in short, when the hinge shaft 221 of the wiper joint 2a and the hinge hole 13a of the wiper connecting base 1a are hinge-connected to each other, the first stopper 23 may be inserted into the receding channel 14 and may be opposite to the first stopper stepped portion 15a (blocking portion a) along the length direction of the connection block 12.
As shown in fig. 3-5 and 3-6, the first limiting step portion 15a of the wiper connecting base 1b is used for ensuring that the front end of the wiper joint 2a is required to be tilted upward by a certain angle when the hinge shaft 221 of the wiper joint 2a is moved out of the hinge hole 13a, so as to facilitate the consumer to grasp the tilted upward angle of the wiper joint 2a when detaching/installing the wiper joint 2a, therefore, the wiper joint 2a is capable of separating from the wiper connecting base 1b only by presetting the included angle γ between the second inclined plane 122 and the front end of the horizontal plane, the included angle γ is not less than or equal to 3 °, the user only needs to abut the inner end of the top wall 21 of the wiper joint 2a against the top of the second inclined plane 122, and the first limiting block 23 of the wiper joint 2a does not interfere with the first limiting step portion 15 a. It should be noted that, when the wiper joint 2a is in the operable state, the front end of the wiper joint 2a will necessarily swing downward relative to the wiper joint 2a in the insertion state, because the wiper joint 2a is fixed 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 (the longitudinal axis R can be understood as the extension line of the wiper arm connecting portion along the length direction when the wiper joint 2a is fixed with the wiper arm connecting portion, in this embodiment, the extension line of the top wall 21 of the wiper joint 2a along the length direction) and the wiper connecting base 1b are in a relatively stable balanced state The seats 1b are parallel to each other along the X-axis direction or the front end of the wiper joint 2a inclines downwards towards 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, in this state, even if the windshield glass is an arc surface, the 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 in the wiping process during the wiping process of the wiper, the 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 less than gamma and generally less than or equal to 0 degrees, the positive value is that the wiper connecting base 1b takes the X-axis direction as the reference, and the clockwise rotation thereof is positive value, the counterclockwise rotation is a negative value, that is, when the longitudinal axis R of the wiper joint 2a is parallel to the wiper connecting base 1b along the X-axis direction, the first limiting block 23 of the wiper joint 2a interferes with the first limiting stepped portion 15a of the wiper connecting base 1b, so that the wiper joint 2a cannot be disengaged from the wiper connecting base 1 b; moreover, in the wiping process (operation state) of the wiper, the relative movement direction between the hinge shaft 221 of the wiper joint 2a and the hinge hole 13a of the wiper connecting base 1b is opposite to the opening 131 direction of the hinge hole 13a, 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. When the wiper joint 2a needs to be detached from the wiper connecting base 1b, 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 forcibly pushed out from the direction of the opening 131 of the hinge hole 13a of the wiper connecting base 1b, and the wiper joint 2a can be detached from the wiper connecting base 1b by abutting against the blocking piece 3 through the hinge shaft 221 of the wiper joint 2a to make the downward position offset, and letting the access passage of the opening 131 of the hinge hole 13a open. 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.
The third embodiment:
referring to fig. 4-1, the present invention discloses a wiper connecting base 1c, which has a structure substantially the same as that of the second embodiment, but a limiting sinking groove 4 is further formed at the top of the connecting block 12 and at the front end of the abdicating channel 14, and the limiting sinking groove 4 is a rectangular sinking groove 41 having a receiving space extending along the length direction of the connecting block 12. In a more preferable design, as shown in fig. 4-2, the limit sinking groove 4 further includes an axial sinking groove 42 extending along a length direction at a rear end of the rectangular sinking groove 41, and a cross section of the rectangular sinking groove 41 and a cross section of the axial sinking groove 42 along a horizontal direction are in a convex shape.

As shown in fig. 4-4, the purpose of additionally providing the limiting sunken groove 4 at the front end of the top of the connecting block 12 of the wiper connecting bases 1c and 1c 'is consistent with the technical effect achieved by the first limiting stepped portion 15a formed by the abdicating channel 14 of the connecting block 12 of the second embodiment, that is, the front end of the wiper joint 2b needs to be tilted up by a certain angle to be separated from the wiper connecting bases 1c and 1 c', otherwise, the front end surface of the second limiting block 24 of the wiper joint 2b in a normal working state interferes with the inner wall of the front end of the limiting sunken groove 4 of the wiper connecting bases 1c and 1c ', so as to limit the wiper joint 2b to be separated from the wiper connecting bases 1c and 1 c', and the specific analysis is detailed in the description of the second embodiment. Meanwhile, the design is optimized, the sinking surface 411 is formed at the front end of the rectangular sinking groove 41, and the yielding inclined surface 241b is further arranged at the bottom of the axial block 24b and on the side far away from the rectangular block 24a, so that the upward tilting angle of the wiper joint 2b relative to the wiper connecting bases 1c and 1c 'can be reduced, the included angle γ between the second inclined surface 122 of the connecting block 12 of the wiper connecting bases 1c and 1 c' and the front end of the horizontal surface is reduced, the connecting block 12 still has a sufficient abutting support area in the area located on the second inclined surface 122, and when the wiper joint 2b is hinged with the wiper connecting bases 1c and 1c ', the wiper joint is not easy to deflect along the width direction relative to the wiper connecting bases 1c and 1 c'.
