DETAILED DESCRIPTION

[0049] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0050] First embodiment, see Figure 1-7 and 10-15.

[0051] The improved windshield wiper structure of the first embodiment includes a vehicle connecting frame 1 , a steel sheet 2 , a bridge bracket 3 , a connecting rail 4 and a wiper member 5 .

[0052] The car connecting frame 1 is provided with a car connecting portion 11 and a steel plate slot 12. The car connecting portion 11 is a prior art, and is used to connect with a wiper swing rod (not shown in the drawings) on the car window. The wiper swing rod can drive the improved wiper structure including the car connecting frame 1 to swing back and forth, and wipe the car window glass through the wiper member 5 described later.

[0053] The side of the steel sheet 2 is provided with a steel sheet notch 21, and the inner side wall of the steel sheet slot 12 is provided with a steel sheet protrusion 121, which is inserted (usually embedded) into the steel sheet notch 21 to limit the movement of the steel sheet 2 relative to the automobile connecting frame 1 along its length direction. The inner side wall of the steel sheet slot 12 is directly or indirectly provided with a steel sheet hook 122, such as Figure 14 ,15 As shown, the vehicle connecting bracket 1 is an integrally formed plastic part. An elastic steel sheet hook body 122 is integrally provided on the inner side wall of the steel plate slot 12, so that the steel sheet hook body 122 is directly provided on the inner side wall of the steel plate slot 12. Of course, as in the fourth and fifth embodiments described later, the steel sheet hook body 122 can be provided through the clip 15, so that the steel sheet hook body 122 is indirectly provided on the inner side wall of the steel plate slot 12. The steel sheet hook body 122 abuts against the bottom end surface of the steel sheet 2, and restricts the steel sheet 2 from detaching from the bottom opening of the steel plate slot 12; thereby enabling the steel sheet 2 and the steel plate slot 12 to be detachably fixedly connected. Usually, a waterproof cover 29 made of rubber or the like surrounds the steel sheet 2.

[0054] The bridge bracket 3 includes a bent bridge body 31. The bending means that both ends of the bridge body 31 are lower than the middle part thereof. For example, the cross section of the bridge body 31 can be integrally annular fan-shaped; a steel plate connecting portion 32 protruding upward is provided in the middle of the bridge bracket 3, and connecting rail mounting portions 33 with a thickness greater than that of the bridge body 31 are provided at both ends of the bridge body 31. A connecting rail connecting groove 331 with a T-shaped cross section is provided in the connecting rail mounting portion 33.

[0055] The connecting rail 4 is flexible and is used to connect the wiping member 5 and the bridge bracket 3.

[0056] The wiping member 5 is flexible and is used to fit against the vehicle window. The wiping member 5 can be a single rubber strip 58 or a single brush 59, or can be a combination of the rubber strip 58 and the brush 59 sharing a wiping member mounting body 51 as described in Embodiment Seven later.

[0057] Both the connecting rail 4 and the wiping member 5 are profiles, that is, the cross sections of the connecting rail 4 (that is, the cross section of the connecting rail 4 intercepted by a plane perpendicular to the length direction of the connecting rail 4 after the connecting rail 4 is flattened. The same applies to the cross sections of other components) are the same, and the cross section of the wiping member 5 is also the same; however, this description does not mean that the cross section of the connecting rail 4 is the same as the cross section of the wiping member 5.

[0058] The connecting rail 4 is usually made of plastic. The connecting rail 4 includes a bridge bracket connecting portion 43 and a wiping member connecting portion 45 provided with a wiping member connecting groove 451; the cross sections of the bridge bracket connecting portion 43 and the wiping member connecting groove 451 are both T-shaped.

[0059] The wiping member 5 includes a wiping member mounting body 51 with a T-shaped cross section, and the wiping member mounting body 51 is embedded in the wiping member connecting groove 451.

[0060] The steel plate connecting portion 32 is detachably connected to the steel sheet 2.

[0061] The bridge support connecting portion 43 sequentially passes through the connecting rail connection grooves 331 of each connecting rail mounting portion 33, so that the connecting rail 4 is connected to the connecting rail mounting portion 33. The wiper element mounting body 51 passes through the wiper element connection groove 451, so that the wiper element 5 is detachably and fixedly connected to the connecting rail 4. It is easy to understand that in this state, the setting directions of the connecting rail 4 and the wiper element 5 are both substantially the same as that of the steel sheet 2. Due to the bent bridge body 31, there are gaps respectively between the top end surfaces of the two sides of the bridge body 31 and the steel sheet. As Figure 6 shown, the gaps on both sides of the steel plate connecting portion 32 enable the bridge support 3 to float, so that the connecting rail 4 and the wiper element 5 can change their shapes according to the shape of the automobile window (such as different arcs, etc.), and can ensure that the wiper element 5 fits the automobile window to ensure the wiping effect.

[0062] As one of the specific embodiments, a contact steel sheet protrusion 311 is provided in the middle of the bridge body 31. For example, the contact steel sheet protrusion 311 is provided outside the following extension body 321, and the contact steel sheet protrusion 311 abuts or is close to the steel sheet 2. The cross section of the contact steel sheet protrusion 311 is a circular segment shape, a triangle shape, a trapezoid shape, etc. It can further increase the floating range of the bridge support 3 and ensure that the wiper element 5 fits the automobile window.

[0063] As one of the specific embodiments, the steel sheet 2 is provided with a through bridge support opening 23; the cross section of the bridge support opening 23 is rectangular. The steel plate connecting portion 32 includes an extension body 321 and an anti-disengagement structure 322 fixedly connected to the extension body 321. The extension body 321 passes through the bridge support opening 23, and the anti-disengagement structure 322 is located above the steel sheet 2 and abuts against the steel sheet 2, so that the steel plate connecting portion 32 is detachably connected to the steel sheet 2.

[0064] As one of the specific embodiments, the anti-disengagement structure 322 is a rectangular body 323, as Figure 7As shown (top view), when viewed from above, the rectangular body 323 and the bridge support opening 23 are both rectangles (i.e., the subordinate concept of a rectangle). It should be noted that the steel plate connection part 32 and the bridge support opening 23 are both set in the direction of the long side of their rectangles. The bridge body 31 is perpendicular to the setting direction of the rectangle of the rectangular body 323; the rectangle of the rectangular body 323 can be completely located within the rectangle of the bridge support opening 23, and when the bridge body 31 is arranged along the length direction of the steel sheet 2, the setting direction of the steel plate connection part 32 is perpendicular to the setting direction of the rectangle of the bridge support opening 23. When installing the bridge support 3, first place the bridge body 31 perpendicular to the length direction of the steel sheet 2. At this time, the setting direction of the rectangle of the rectangular body 323 is the same as the setting direction of the rectangle of the bridge support opening 23. After the rectangular body 323 can pass through the bridge support opening 23, rotate the bridge body 31 so that it rotates to the length direction of the steel sheet 2. The rectangular body 323 (i.e., the subordinate of the anti-disengagement structure 322) is located above the steel sheet 2 and abuts against the steel sheet 2, so that the steel plate connection part 32 is detachably connected to the steel sheet 2; then install the connecting rail 4 and the brushing member 5 on the connecting rail installation part 33 of the bridge support 3, which can facilitate the installation of the bridge support 3 on the steel sheet 2. After the connecting rail 4 and the brushing member 5 are connected to the bridge support 3, the rotation direction of the bridge body 31 is locked and cannot be rotated back, which can ensure the stable connection between the bridge support 3 and the steel sheet 2 after assembly.

[0065] As one of the specific embodiments, as Figure 7 shown, one side of the extension body 321 extends in a direction perpendicular to the length of the steel sheet 2 to form a transverse opening 231; when the bridge body 31 rotates to the length direction of the steel sheet 2, the width of the extension body 321 is greater than the width of the bridge support opening 23 and there is a part of the extension body 321 located in the transverse opening 231. At this time, the bridge support 3 cannot move along the length direction of the steel sheet 2 and is fixed, which can improve the connection strength and stability between the bridge support 3 and the steel sheet 2.

[0066] As one of the specific embodiments, a contact connecting rail protrusion 332 is provided at the lower end of the connecting rail installation part 33. It can make the connecting rail 4 float relative to the connecting rail installation part 33 to ensure that the brushing member 5 fits the car window.

[0067] The end buckle cap 6 includes an end buckle cap end wall 61 and two end buckle cap side walls 62, such that when viewed from above, the end buckle cap 6 is U-shaped as a whole. The side wall of the connecting rail mounting portion 33 is provided with an end buckle cap snap groove 34, and the inner side wall of the end buckle cap side wall 62 is provided with an end buckle cap snap 621. The end buckle cap snap 621 snaps into the end buckle cap snap groove 34, such that the inner side wall of the end buckle cap end wall 61 abuts against the connecting rail mounting portion 33, the brush member 5, and the connecting rail 4, thereby restricting the brush member 5 and the connecting rail 4 from moving relative to the connecting rail mounting portion 33 along its length direction. When installing the connecting rail 4 and the brush member 5, first insert the brush member mounting body 51 into the brush member connecting groove 451, such that the two coincide and are connected to each other in the length direction; then sequentially pass the bridge support connecting portion 43 through the connecting rail connecting groove 331 of the connecting rail mounting portion 33; then snap the end buckle cap snap 621 into the end buckle cap snap groove 34, such that the inner side wall of the end buckle cap end wall 61 abuts against the connecting rail mounting portion 33, the brush member 5, and the connecting rail 4. The brush member 5 and the connecting rail 4 are restricted from moving relative to the connecting rail mounting portion 33 along its length direction by the end buckle cap 6 and will not fall off from the connecting rail mounting portion 33, nor will they separate from each other. It can be seen from this paragraph that for the connecting rail 4 and the brush member 5 which are profiles, it is convenient to install the end buckle cap 6, and it can prevent the connecting rail 4 and the brush member 5 from falling off or separating from each other.

[0068] As one of the specific embodiments, the inner side wall of the end buckle cap side wall 62 is provided with an end buckle cap guide rail 622 along the length direction of the connecting rail 4, and the side wall of the connecting rail mounting portion 33 is provided with an end buckle cap guide groove 341; the end buckle cap guide rail 622 is embedded in the end buckle cap guide groove 341. It can also ensure the connection strength between the end buckle cap 6 and the connecting rail mounting portion 33, and it is not easy for the two to shake up and down.

[0069] As one of the specific embodiments, one edge of the inner side of the end buckle cap snap 621 (i.e., the side of the end buckle cap snap 621 close to the steel plate connecting portion 32 after the end buckle cap snap 621 snaps into the end buckle cap snap groove 34) is provided with an inclined surface (not marked in the drawing). The inner inclined surface of the end buckle cap snap 621 can play a guiding role, facilitating the end buckle cap snap 621 to snap into the end buckle cap snap groove 34 when the end buckle cap 6 moves from the connecting rail mounting portion 33 to the steel plate connecting portion 32.

[0070] As one of the specific embodiments, the end cap guide rail 622 faces the end cap buckle 621 and its thickness (the dimension in the direction towards the inner side of the end cap side wall 62) is less than the thickness of the end cap buckle 621. It is easy to understand that the end cap guide groove 341 also faces the end cap buckle groove 34. When moving the end cap 6 from the connecting rail mounting portion 33 to the steel plate connecting portion 32 so that the end cap buckle 621 is snapped into the end cap buckle groove 34, the end cap buckle 621 first embeds into the end cap guide groove 341 and moves along the end cap guide groove 341. Until the end cap buckle 621 is snapped into the end cap buckle groove 34, the end cap guide rail 622 embeds into the end cap guide groove 341, which can realize the pre-alignment of the end cap buckle 621 and the end cap buckle groove 34 for easy assembly, and can also ensure the connection strength between the end cap 6 and the connecting rail mounting portion 33, and it is not easy for the two to shake up and down.

[0071] As one of the specific embodiments, the inner side wall of the end cap side wall 62 is further provided with a connecting rail fixing groove 623 located below the end cap buckle 621, and the brush member connecting portion 45 is embedded in the connecting rail fixing groove 623. It can ensure the connection strength between the end cap 6 and the connecting rail mounting portion 33, and it is not easy for the two to shake up and down.

[0072] As one of the specific embodiments, a compression body 611 is provided on the inner side wall of the end cap end wall 61; the compression body 611 abuts against the brush member 5 to compress the brush member 5. The brush member 5 is slightly compressed along its length direction, so that the brush member 5 is slightly bent to increase the pressure and friction force between the brush member mounting body 51 and the brush member mounting body 51, and the connection strength after the assembly between the connecting rail 4 and the brush member 5 can be ensured.

[0073] Second and third embodiments. Refer to Figure 8 、 9 。

[0074] The improved wiper structure of the second and third embodiments is different from that of the first embodiment in that the bridge bracket 3 is different.

[0075] As Figure 8 shown, in the improved wiper structure of the second embodiment, the bridge bracket 3 is made of plastic and has elasticity. The extension body 321 is provided with an elastic relief opening 324. The anti-disengagement structure 322 of the bridge bracket 3 is a steel sheet snap 325. The direction of the steel sheet snap 325 towards the elastic relief opening 324 is perpendicular to the bridge body 31. The exposed side wall of the elastic relief opening 324 of the extension body 321 abuts against the inner wall of the bridge bracket opening 23. When the bridge bracket 3 is brought close to the steel sheet 2, the extension body 321 undergoes elastic deformation, and the steel sheet snap 325 passes through the bridge bracket opening 23 and abuts against the steel sheet 2. In the second embodiment, it is convenient for the installation of the end cap 6, but it is not as convenient as the first embodiment to disassemble the bridge bracket 3 from the steel sheet 2 (for example, rework is required during assembly, etc.).

[0076] As shown Figure 9 in the figure, the improved wiper structure of the third embodiment, the bridge bracket 3 is made of a metal sheet and has elasticity, for example, the same material as the steel sheet 2; the extension body 321 is provided with an elastic relief opening 324, as shown Figure 9 in the figure, two metal sheets bent upward relative to the bridge body 31 realize that the extension body 321 is provided with an elastic relief opening 324, and the bottom end surface of the elastic relief opening 324 is provided with a spherical segment-shaped (i.e., the shape of the remaining part after the spherical shape is intercepted by a plane) contact steel sheet protrusion 311 (because the thickness of the metal sheet is approximately equal, the back surface of the contact steel sheet protrusion 311 has a spherical segment-shaped groove). Similar to the first embodiment, the contact steel sheet protrusion 311 is used to further increase the floating range of the bridge bracket 3 and ensure that the wiping member 5 fits the automobile window, and the spherical segment-shaped contact steel sheet protrusion 311 is relatively easy to be formed by stamping for the bridge bracket 3 made of a metal sheet, which is beneficial to reducing the manufacturing cost of the bridge bracket 3.

[0077] The fourth, fifth, and sixth embodiments. Refer to Figures 16-26 .

[0078] It can be compared with Figure 14 and 15 the automobile connecting frame 1 of the first embodiment shown in the figure. The automobile connecting frame 1 of the first embodiment is an integrally formed structure made of plastic, and its automobile connecting portion 11 is not replaceable. When it is necessary to change the automobile connecting portion 11 corresponding to the automobile swing rod, although the structures of the steel plate card slot 12 and the steel sheet protrusion 121 and the steel sheet hook body 122 therein can be universal, because the automobile connecting portion 11 is not replaceable, it is necessary to change the steel plate card slot 12 along with the change of the automobile connecting portion 11, and usually multiple molds need to be opened. Therefore, from the overall view of multiple different automobile connecting frames 1 (i.e., multiple models of automobile connecting frames 1), the overall manufacturing cost of multiple models of automobile connecting frames 1 is relatively high. It can be seen that there is room for improvement in the versatility of the automobile connecting frame 1 of the first embodiment.

[0079] The improved wiper structure of the fourth embodiment is different from that of the first embodiment in the automobile connecting frame 1

[0080] The improved wiper structure of the fourth embodiment, the automobile connecting frame 1 includes an automobile connecting member 13 and a steel plate card seat 14, the automobile connecting portion 11 is arranged on the automobile connecting member 13, and the steel plate card slot 12 is arranged on the steel plate card seat 14; the automobile connecting member 13 and the steel plate card seat 14 are detachably and fixedly connected. It is possible to replace only the automobile connecting member 13 as needed, which can improve the versatility and reduce the overall cost of multiple models of automobile connecting frames 1.

[0081] As one of the specific embodiments, the vehicle connector 13 is linearly slidably connected to the steel plate clamping seat 14 along the steel plate slot 12 (i.e., the direction between the two openings of the steel plate slot 12 for the steel sheet 2 to pass through). For example, the vehicle connector 13 is provided with an anti-sway body 133, and the steel plate clamping seat 14 is provided with an anti-sway groove 144 arranged along the steel plate slot 12. The anti-sway body 133 is embedded in the anti-sway groove 144 so that the vehicle connector 13 is linearly slidably connected to the steel plate clamping seat 14 along the steel plate slot 12 and prevents swaying. The vehicle connector 13 is provided with a clamping seat fixing hole 131, and the top end of the steel plate clamping seat 14 is provided with an elastic strip 142 along the steel plate slot 12, and a clamping seat buckle body 141 is arranged on the elastic strip 142. The clamping seat buckle body 141 is embedded in the clamping seat fixing hole 131. When assembling the vehicle connector 13 and the steel plate clamping seat 14, the anti-sway body 133 is inserted along the anti-sway groove 144 until the clamping seat buckle body 141 is inserted into the clamping seat fixing hole 131, and the vehicle connector 13 and the steel plate clamping seat 14 are fixed. It can be seen that the assembly between the vehicle connector 13 and the steel plate clamping seat 14 can be completed more conveniently.

[0082] As one of the specific embodiments, the top end of the clamping seat fixing hole 131 is exposed from the vehicle connector 13. During assembly, it can be confirmed through the clamping seat fixing hole 131 that the clamping seat buckle body 141 is embedded in the clamping seat fixing hole 131, which is beneficial to improving the quality.

[0083] As one of the specific embodiments, the vehicle connector 13 is provided with an elastic strip groove 132 facing the clamping seat fixing hole 131, and the elastic strip 142 is embedded in the elastic strip groove 132. Only one end of the elastic strip groove 132 is exposed from the side of the vehicle connector 13. A fitting inclined surface 134 is arranged on the side of the clamping seat fixing hole 131 opposite to the opening of the elastic strip groove 132 (i.e., the opening exposed from the side of the vehicle connector 13), and the clamping seat buckle body 141 is provided with an inclined surface. The inclined surface of the clamping seat buckle body 141 is in contact with the fitting inclined surface 134. The clamping seat buckle body 141 is slid into the clamping seat fixing hole 131 from the opening of the elastic strip groove 132 until the clamping seat buckle body 141 is embedded in the clamping seat fixing hole 131. During this process, the clamping seat buckle body 141 plays a guiding role, facilitating the assembly between the vehicle connector 13 and the steel plate clamping seat 14. After the clamping seat buckle body 141 is embedded in the clamping seat fixing hole 131, the rear side wall is completely in contact, and the connection between the vehicle connector 13 and the steel plate clamping seat 14 is relatively stable.

[0084] As one of the specific embodiments, a hollow groove 143 penetrating through to the steel plate slot 12 is arranged around the elastic strip groove 132. After the steel sheet 2 is installed in the steel plate slot 12, it abuts against the bottom end of the elastic strip 142, which can prevent the clamping seat buckle body 141 from moving downward and disengaging from the clamping seat fixing hole 131, that is, it can improve the reliability of the connection between the vehicle connector 13 and the steel plate clamping seat 14 after the wiper is assembled.

[0085] As one of the specific embodiments, as shown in FIG. 21, the top end of the steel plate card slot 12 extends upward to form an avoidance slot 145, and the width of the avoidance slot 145 (the dimension in the direction perpendicular to the steel plate card slot 12) is smaller than the width of the steel plate card slot 12. For the case where the automotive connector 13 and the steel plate card holder 14 need to be easily separated, the avoidance slot 145 allows the elastic strip 142 to bend downward; applying a relatively large force to push the steel plate card holder 14 (i.e., continuing to push in the direction of sliding the card holder buckle body 141 into the opening of the elastic strip groove 132), the automotive connector 13 and the steel plate card holder 14 can be separated; that is, the automotive connector 13 and the steel plate card holder 14 can be separated more conveniently after the wiper is assembled.

[0086] As one of the specific embodiments, as Figure 19 、 20 shown, it further includes a clip 15. The clip 15 is provided with a clip buckle body 151. The steel sheet hook body 122 is arranged on the clip buckle body 151. A clip installation groove 152 is formed in the side wall of the steel plate card holder 14. An inner stopper 154 and a clip buckle opening 153 penetrating through the steel plate card slot 12 are arranged in the clip installation groove 152. The clip 15 is embedded in the clip installation groove 152 so that the clip buckle body 151 passes through the clip buckle opening 153 and abuts against the inner side wall of the steel plate card slot 12, and the steel sheet hook body 122 extends into the steel plate card slot 12. After the steel sheet 2 is placed into the steel plate card slot 12, the clip 15 is embedded in the clip installation groove 152, so that the steel sheet hook body 122 extends into the steel plate card slot 12 and abuts against the bottom end surface of the steel sheet 2, which can more conveniently complete the installation of the steel sheet 2 and is also convenient for the automated production of the steel sheet 2.

[0087] As one of the specific embodiments, the clip buckle body 151 is at least one group, and the clip buckle bodies 151 in one group are mirror-symmetrical to each other. As Figure 20 shown, there are two groups of clip buckle bodies 151 on one clip 15, and the clip buckle bodies 151 in each group are mirror-symmetrical to each other. It can ensure a firm connection between the clip 15 and the steel plate card holder 14.

[0088] The improved wiper structure of the fifth embodiment is different from that of the fourth embodiment in terms of the automotive connector 13, the steel plate card holder 14, and the clip 15.

[0089] As Figure 23 、 24As shown, in the improved wiper structure of the fifth embodiment, both ends of the elastic strip groove 132 are exposed from the side of the automobile connector 13, the base buckle body 141 and the elastic strip 142 are at least one group, and one group of the base buckle body 141 and the elastic strip 142 are two mutually mirror-symmetrical (mirror-symmetrical about the plane perpendicular to the steel plate slot 12). It is easy to understand that the base fixing hole 131 and the elastic strip groove 132 also correspond to the base buckle body 141 and the elastic strip 142, that is, the base fixing hole 131 and the elastic strip groove 132 are at least one group, and one group of the base fixing hole 131 and the elastic strip groove 132 are two mutually mirror-symmetrical. The sliding connection between the automobile connector 13 and the steel plate base 14 is not limited to a single direction and is relatively convenient, and after the base buckle body 141 is respectively inserted into the base fixing hole 131, the automobile connector 13 and the steel plate base 14 are difficult to separate.

[0090] like Figure 23 As shown in the figure, as one of the specific embodiments, the clip buckle body 151 extends away from the steel plate slot 12 to form a toggle body 155 and a toggle slot 156. The toggle body 155 is bent so that the clip buckle body 151 does not abut against the inner wall of the steel plate slot 12, that is, the clip buckle body 151 can be removed from the steel plate holder 14, which is convenient for rework or replacement of the steel sheet 2.

[0091] The improved wiper structure of the sixth embodiment is different from that of the fourth embodiment in that the automobile connecting member 13 and the steel plate holder 14 are detachably connected.

[0092] In the improved wiper structure of the sixth embodiment, the automobile connector 13 and the steel plate holder 14 are both made of metal sheets. The automobile connector 13 is provided with a bent connecting ear 139, and the steel plate holder 14 is provided with a bent connecting ear groove 149. The bent connecting ear 139 fits through the bent connecting ear groove 149 and then bends and abuts against the steel plate holder 14, so that the automobile connector 13 and the steel plate holder 14 are detachably connected.

[0093] Seventh embodiment.

[0094] The improved wiper structure of the seventh embodiment is different from that of the first embodiment in the rubber strip connecting rail 4 and the wiper member 5 .

[0095] In the improved wiper structure of the seventh embodiment, the rubber strip connecting rail 4 is provided with a plurality of brush member connecting grooves 451, and the brush member 5 includes a rubber strip 58 and / or a brush 59; the brush member mounting body 51 of the rubber strip 58 and the brush member mounting body 51 of the brush 59 are respectively embedded in the brush member connecting grooves 451. Different brush members 5 can be combined as needed, such as a brush member 5 with double rubber strips 58, such as a brush member 5 with a brush 59 arranged inside the double rubber strip 58.
