As shown in fig. 2-3 to fig. 2-5, the wiper joint 2a and the wiper connecting base 1a are specifically installed by placing the wiper joint 2a above the wiper connecting base 1a, facing the first latch 23 and the second latch 24 to the insertion passages 53a, 53b of the connecting block 12, and then sleeving the first latch 23 and the second latch 24 of the wiper joint 2a from top to bottom along the insertion passages 53a, 53b of the connecting block 12 until the bottom end surface of the wiper joint 2a and the supporting plane 111 of the wiper connecting base 1a are in contact with each other, at this time, the connecting block 12 is placed in the inner cavity of the longitudinal body of the wiper joint 2a, so that the inner ends of the two side walls 21 of the wiper joint 2a are in contact with the two side surfaces 125 of the connecting block 12, respectively, thereby limiting the relative displacement of the wiper joint 2a with respect to the wiper connecting base 1a in the width direction, then, the wiper joint 2a is translated from front to back until the inner wall of the front end wall 29 of the wiper joint 2a and the limiting and stopping surface 121 at the front end of the connecting block 12 are abutted and limited to limit the backward relative displacement of the wiper joint 2a relative to the wiper connecting base 1a along the longitudinal direction, at this time, the first fixture block 23 and the second fixture block 24 of the wiper joint 2a are respectively clamped in the first limiting slot 51 and the second limiting slot 52 which are correspondingly arranged, the bearing hole 25 is located at the rear end of the stopping part 13 of the connecting block 12, the top end surfaces of the first fixture block 23 and the second fixture block 24 are abutted against the transverse stopping surfaces 511 and 521 of the first limiting slot 51 and the second limiting slot 52 respectively, so as to limit the relative displacement of the wiper joint 2a relative to the wiper connecting base 1a along the vertical direction; at this time, the preliminary assembly of the wiper joint 2a and the wiper connecting base 1a is completed, the receiving hole 25 is located at the rear end of the stop portion 13 of the connecting block 12 (normally, due to the limitation of processing precision and the like, the receiving hole 25 is generally disposed at the rear end of the first limiting surface 131 of the stop portion 13 with a clearance, the minimum distance between the inner diameter end facing to the first limiting surface 131 and the first limiting surface 131 is generally 0.2mm-0.5mm), and the height of the lowest point of the receiving hole 25 is greater than or equal to the height of the top of the connecting block 12 opposite to the lowest point, then the hinge shaft S of the side-inserted wiper arm is inserted into the receiving hole 25, the outer diameter end of the hinge shaft S can be abutted and matched with the first limiting surface 131 of the stop portion 13, thereby limiting the forward relative displacement of the wiper joint 2a relative to the wiper connecting base 1a in the longitudinal direction, and realizing that the wiper joint 2a is stably disposed on the wiper connecting base 1a, finally, the free end of the L-shaped connecting arm of the short side-inserting type scraping arm K2 is inserted into the limiting groove 27a of the wiper connector and forms limiting along the width direction with the first limiting matching surface C, so that the short side-inserting type scraping arm K2 is assembled with the wiper connecting assembly; the inner end of the free end of the L-shaped connecting arm of the long side-inserted type scraping arm K1 and the second limit matching surface D of the wiper connector 2a form a limit along the width direction, so that the long side-inserted type scraping arm K1 and the wiper connecting assembly are assembled. It should be noted that, if the wiper fitting 2a does not have the front end wall 29, or does not rely on the front end wall 29 and the limit stop surface 121 at the front end of the connecting block 12 to abut against each other for support, the first fixture block 23 and/or the second fixture block 24 can directly abut against and limit the longitudinal abutting surfaces 512 and 522 of the first limiting slot 51 and the second limiting slot 52, but it is preferable that the front end wall 29 of the wiper fitting 2a and the limit stop surface 121 of the connecting block 12 are abutted against each other for limiting, since the abutting limit area of the latter is larger than the abutting area of the former, since the height of the connecting block 12 of the present embodiment is low, the beneficial effect is not obvious, in the subsequent embodiment, the height of the front end of the connecting block 12 is higher, the limit resisting surface 121 with larger area is provided, therefore, the limiting effect is better, and the stability of the wiper joint 2a and the wiper connecting base 1a can be effectively improved. When the windshield wiper joint 2a is required to be separated from the windshield wiper connecting base 1a, the L-shaped connecting arm of the side-inserted type scraping arm is separated from the first limit matching surface C or the second limit matching surface D for limitation, and the articulated shaft S is outwards pulled out from the inserting and receiving hole B of the windshield wiper joint, so that the separation of the windshield wiper joint 2a and the windshield wiper connecting base 1a can be realized, and the detachment/installation of the windshield wiper joint 2a and the windshield wiper connecting base 1a is very convenient.

More preferably, the wiper joint 2a may be symmetrically designed along the longitudinal central axis M, that is, the inserting receiving hole B, the limiting groove 27a and the second limiting fitting surface D of the wiper joint 2a are symmetrically designed along the longitudinal central axis M of the wiper joint 2a, so that the hinge shaft S of the side inserting type wiper arm may be inserted from the inserting receiving hole 25 in any side direction, thereby facilitating the side inserting type wiper arm to be mounted on the left-hand vehicle or the right-hand vehicle in an adaptive manner.

Second embodiment:

as shown in fig. 2-6 to 2-8, compared with the first embodiment, the structure of the top part of the connecting block 12 of the wiper connecting base 1b is eliminated from the stop part 13, and the connecting block 12 is formed with an L-shaped depressed part 14 extending in the longitudinal direction at the rear end at a position located substantially near the middle, the L-shaped depressed part 14 is formed with a stopping end surface 141 facing the rear end, and the stopping end surface 141 is used for abutting against the hinge axis S of the limit side insertion type wiper arm; the first limiting slots 51 are arranged on two side surfaces 125 of the L-shaped sinking part 14; meanwhile, the top of the connecting block 12 is provided with a limiting step part 15, and the limiting step part 15 is provided with a second limiting surface 151 facing to the rear end; the wiper joint 2b has a structure substantially identical to that of the wiper joint 2a of the first embodiment, except that a stopper click 26 is provided at the inner end of the top wall 22 of the wiper joint 2b and at a position opposite to the stopper step 15 of the connecting piece 12, the limiting stop 26 can abut against the limiting step 15 for limiting the forward relative displacement of the wiper fitting 2b relative to the wiper connecting base 1b along the longitudinal direction, and when the wiper fitting 2b is separated from the connecting block 12 by an external force, the limiting clamping point 26 is easy to deform and is crossed and separated from the top of the limiting step part 15, and by the design, after the windshield wiper joint 2b and the windshield wiper connecting base 1b are installed in place, if there is no external force, the two can be relatively fixed, the articulated shaft S of the side-inserting type scraping arm is conveniently inserted into the bearing hole 25 of the wiper joint 2b, and the final stable connection between the two is realized.

The method of removing/attaching the wiper joint 2B to the wiper connecting base 1B is substantially the same as that of the first embodiment except that since the connecting block of the wiper connecting base 1B forms the L-shaped depressed portion 14, when the two are assembled in place, the receiving hole 25 of the wiper joint 2B is located in the region of the L-shaped depressed portion 14 of the opposing connecting block 12, and the front end of the receiving hole 25 is located at the rear end of the end face 141 abutting against the L-shaped depressed portion 14, and the distance between the receiving hole 25 and the abutting end face 141 is set as in the first embodiment, not described above, so that the hinge shaft S of the side-insertion type wiper arm is inserted in the empty space formed above the receiving hole 25 of the wiper joint 2B and the L-shaped depressed portion 14 in turn, and the front side of the hinge shaft S is allowed to abut against the abutting end face 141 of the L-shaped depressed portion 14 of the connecting block 12, thereby restricting the relative displacement of the wiper joint 2B forward in the longitudinal direction with respect to the wiper connecting base 1B, the windshield wiper joint 2b is stably arranged on the windshield wiper connecting base 1 b; compared with the first embodiment, the front area (including the position-limiting abutment surface 121 and the two side surfaces 125) of the connecting block 12 of the wiper connecting base 1b has a larger abutment support area with the corresponding position of the wiper joint 2b, so that a tight connection relationship is established between the wiper joint 2b and the wiper connecting base 1 b.

In a third embodiment of the present invention, the first,

as shown in fig. 2-9 to fig. 2-12, the present invention discloses a wiper connecting base 1c, the structure of which is substantially the same as that of the wiper connecting base 1b disclosed in the second embodiment, the most obvious difference is that the connecting block 12 of the wiper connecting base 1c is additionally provided with a through hole 16a or a through channel 16b at the front end of the L-shaped sinking portion 14 for passing through the hinge axis S of the side-inserted type wiper arm, and the through channel 16a is a U-shaped section of the connecting block 12 vertically downward along the longitudinal direction (refer to fig. 3-2); the most obvious difference between the wiper joint 2c and the wiper joint 2b disclosed in the second embodiment is that the longitudinal section T of the wiper joint 2c forms a longitudinal relief portion 17 extending from front to back along the longitudinal direction relative to the position of the stop end face 141 of the L-shaped depressed portion 14, so that the wiper joint 2c can be conveniently mounted on the wiper connecting base 1c, the longitudinal relief portion 17 of the wiper joint 2c needs to reserve enough relief space for the wiper joint 2c and the wiper connecting base 1c to relatively displace along the longitudinal direction, fig. 2-10 disclose that the wiper joint 2c is a schematic diagram symmetrically distributed along the longitudinal central axis M, and is used for adapting to a side-inserted wiper arm of a left-rudder vehicle or a right-rudder vehicle, and the longitudinal relief portion 17 is arranged in the middle of the front end of the longitudinal section T; fig. 2-11 show that the limiting groove 27a of the wiper fitting 2C ' is of single-edge design, and a filling portion 28 having a contour substantially corresponding to that of the wiper fitting 2C ' is added side by side, the filling portion 28 may be a solid member having a length equal to that of the wiper fitting 2C ' or a hollow member with a downward opening (as shown in fig. 2-12), a plurality of ribs are added in the member for increasing the overall strength, and the filling portion 28 is also provided with a through hole 281 penetrating the receiving hole 25, the through hole 281 is defined as an insertion receiving hole B for inserting the hinge shaft S of the side-insertion type wiper arms K1, K2, and the filling portion 28 also forms a longitudinal section extending downward along the longitudinal direction for supporting the L-shaped connecting arm, the distance between the mating end surface of the insertion receiving hole 281B and the first limiting mating surface C and the second limiting mating surface D is adjusted by the filling portion 28, the abutting support area between the wiper joint 2c' and the wiper connecting base 1c is further increased, and the stability of the connection between the wiper joint and the wiper connecting base is increased. Meanwhile, the wiper blade 2c' is formed with a longitudinal relief portion 17 which is located at the front end of the longitudinal section T and communicates with the stopper groove 27 a. When the wiper joints 2c, 2c 'and the wiper connecting base 1c are installed in place, the receiving holes 25/through holes 281 of the wiper joints 2c, 2c' are opposite to the through holes 16a or the through passages 16b of the connecting block 12 for the hinge shafts S of the side-insertion type wiper arms to pass through, and the above-mentioned structural changes can realize a more secure connection relationship between the wiper joints 2c, 2c 'and the wiper connecting base 1c because the wiper joints 2c, 2c' and the wiper connecting base 1c generate forward centrifugal force when the wiper connecting assembly is in an operating state, but the structures of the wiper connecting bases 1a, 1b disclosed in the first and second embodiments cannot directly restrict the outward relative movement (generated by the centrifugal force) of the hinge shafts S of the side-insertion type wiper arms, and only can pass through the wiper joints 2a, The front end wall 29 of the wiper joint 2a and the receiving hole 25 of the wiper joint 2b are supported against the limiting and resisting surface 121 at the front end of the connecting block 12, and the receiving hole 25 of the wiper joint 2a and 2b is subjected to an outward centrifugal force applied by the wiper joint and the wiper connecting bases 1a and 1b, so that the receiving hole 25 bears a large acting force; in the present embodiment, the side-insertion hinge shaft S can directly and physically contact with the through hole 16a or the through channel 16b of the wiper connecting base 1c, so as to partially overcome the outward centrifugal force of the wiper connecting base 1c, thereby reducing the load on the receiving holes of the wiper joints 2c, 2 c'.

A second series: the windshield wiper joint forms an insertion limit space at the longitudinal section position

The first embodiment:

as shown in fig. 3-1 to fig. 3-4, the wiper connecting base 1d disclosed in the present embodiment is most similar to the wiper connecting base 1C disclosed in the first series of third embodiments, and the most obvious difference therebetween is that the connecting block 12 of the wiper connecting base 1d is not designed with the L-shaped depressed portion 14, the position of the connecting block 12 relative to the wiper joint longitudinal section T is defined as a limit fitting section G, the height of the limit fitting section G is less than or equal to the height of the wiper joint longitudinal section T, and a first limit fitting surface C is formed on one side end surface of the limit fitting section G.

The most obvious difference between the wiper joint 2D disclosed in this embodiment and the wiper joints 2a, 2b, 2C disclosed in the first series of embodiments is that the design of the limiting groove 27a is eliminated at the position of the longitudinal section T of the longitudinal body of the wiper joint 2D, and is changed into the design of the hollow portion 221, that is, the top wall 22 of the wiper joint 2D forms a hollow portion 221 at the position of the longitudinal section T, the hollow portion 221 is used to expose the limiting matching section G of the connecting block 12, and an L-shaped connecting arm inserting limiting space 27b for a side-inserted type wiper arm is formed between the hollow portion 221 of the top wall 22 and a side end face of the limiting matching section G of the connecting block 12, the side end face forms a first limiting matching surface C, the side end face of the side wall 21 adjacent to the first limiting matching surface C forms a second limiting matching surface D, and the first limiting matching surface C and the second matching surface D respectively form a first width W1 and a second width W1 to the matching end face of the receiving hole 25 at the opposite side A W2 degree, defined as an insertion receiving hole B at the side receiving hole 25, different widths for adapting to the side insertion type scraping arms of different L-shaped connecting arms (as shown in FIGS. 3-5 to 3-6) consistent with the above description; meanwhile, the design is optimized, a blocking edge 211 facing the first limit matching surface of the limit matching section G is formed at the bottom of the side wall 21 of the wiper joint 2d, and the blocking edge 211 can be abutted against the first limit matching surface C to further increase the limit surface of the wiper joint 2d and the wiper connecting base 1d along the width direction, so that the connection stability of the wiper joint 2d and the wiper connecting base is improved.

Meanwhile, fig. 3-1 also discloses a wiper connecting base 1d, which can also be adapted to a wiper joint (non-adapted side-inserted wiper arm) with hinged shafts on both side walls, that is, a through hole 16a is arranged below the limiting step part 15 (because the limiting step part 15 is generally arranged in the region of the topmost part of the connecting block 12), so that the conventional wiper joint with hinged shafts on both side walls can be sleeved in the through hole 16a to realize pivotal connection, and in order to facilitate the sliding of the hinged shafts of the wiper joint into the through hole 16a, guide slopes 152 are formed on both side surfaces of the limiting step part 15, in fact, each embodiment with a through hole disclosed in the present invention can be adapted to the conventional wiper joint with hinged shafts on both side walls by using the inventive concept.

Second embodiment:

as shown in fig. 3-7 to fig. 3-12, the wiper connecting base 1e of the present embodiment has a structure substantially identical to that of the wiper connecting base 1d, and the most obvious difference is that the wiper connecting base 1e is located in the region of the limit fitting section G of the connecting block 12, and at least one section of positioning baffle 19 recessed inwards (first inward-concave) is formed on both sides of the wiper connecting base along the longitudinal direction and from top to bottom, and the width of the positioning baffle 19 is less than the width of the connecting block 12; the connecting block 12 of the wiper connecting base 1e is also provided with a settlement section 18 which extends backwards along the longitudinal direction at the rear end of the positioning baffle 19, the width of the settlement section 18 is flush with the connecting block 12, and the first limiting slot 51 is arranged on two side surfaces of the settlement section 18; meanwhile, the connection block 12 is also recessed inwards (second inward shrinkage) below the positioning baffle 19 to form a guide projection 20, the second inward shrinkage is smaller than the first inward shrinkage, that is, the width of the connection block 12 is greater than the width of the guide projection 20 is greater than the width of the positioning baffle 19, the lateral end face of the guide projection 20 is flush with the inner side end face of the first limiting slot 51, and the arrangement of the guide projection 20 facilitates the insertion of the first fixture 23 of the wiper joint 2e into the first limiting slot 51. This embodiment also discloses a configuration in which the connecting block 12 is offset to one side of the support plane 111 along the longitudinal center axis Z (see fig. 3-7).

The wiper joint 2e disclosed in this embodiment is substantially identical to the structure of the wiper joint 2d described above, mainly because the connecting block 12 of the wiper connecting base 1e is offset, so that the wiper joint 2e adds the structural feature of the filling portion 28, and the structural feature of the filling portion 28 can refer to the structure of the wiper joint 2 d' disclosed in the third embodiment of the first series, and will not be described in detail again.

After the wiper connector 2e is stably connected to the wiper connecting base 1e, an insertion limiting space 27B for inserting the L-shaped connecting arm of the side-inserted wiper arm is formed between the hollow portion 221 of the top wall 22 of the wiper connector 2e and the positioning baffle 19, the positioning baffle 19 forms a first limiting matching surface C on one side end surface of the insertion limiting space 27B, a second limiting matching surface D on the outer side end surface of the side wall 21 adjacent to the first limiting matching surface C, the first limiting matching surface C and the second limiting matching surface D respectively form a first width W1 and a second width W2 between the matching end surfaces of the bearing holes 25 (through holes located in the filling portion of the wiper connector 2e) on the opposite side, and the bearing holes 25 located on the side are defined as insertion bearing holes B. By means of side-inserted scraper arms of different widths for adapting to different L-shaped connecting arms (see fig. 3-11 to fig. 3-12).

As shown in fig. 3-13, the wiper connecting base 1e ' is completely identical in structure to the wiper connecting base 1e, except that the offset design of the connecting block 12 is eliminated, and the wiper joints 2e ' adapted thereto are symmetrically disposed along the longitudinal central axis M, it should be noted that, because the width of the positioning baffle 19 is relatively thin (compared to the connecting block 12), the two side walls 21 of the wiper joint 2e ' can be designed to be retracted toward the longitudinal central axis M in the region of the longitudinal section T, and the bottom of the two side walls 21 (in the region of the longitudinal section) form a bottom edge 212 extending outward opposite to the longitudinal central axis M, and the bottom edge 212 increases the abutting support area between the wiper joint 2e ' and the support plane 111 of the wiper connecting base 1e ', thereby improving the stability of the connection therebetween; the length of the inserting type bearing hole B extending outwards is set, so that the distance between the matching end face of the inserting type bearing hole B and the first limiting matching surface C or the second limiting matching surface D meets the requirement, and the use requirement of the side inserting type scraping arm of the adaptive left-rudder vehicle or right-rudder vehicle is met through the design.

The present invention further discloses a wiper (not shown) comprising the wiper connecting assembly of any one of the above embodiments, wherein the wiper connecting assembly can connect the wiper support assembly with at least two side-inserted wiper arms having different L-shaped connecting arm lengths.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes and modifications may be made by one of ordinary skill in the art without departing from the scope of the present invention.
