DETAILED DESCRIPTION

[0055] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0056] First embodiment, see Figure 1-7 and 10-15.

[0057] 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 .

[0058] 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.

[0059] 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. The steel sheet protrusion 121 is inserted (usually embedded) into the steel sheet notch 21 to restrict the movement of the steel sheet 2 relative to the vehicle 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 body 122. For example, as Figure 14 , 15 shown, the vehicle connecting frame 1 is an integrally formed plastic part, and the inner side wall of the steel sheet slot 12 is integrally provided with an elastic steel sheet hook body 122, so that the inner side wall of the steel sheet slot 12 is directly provided with the steel sheet hook body 122. Of course, as in the fourth and fifth embodiments described later, the steel sheet hook body 122 can be set by a clip 15, so that the inner side wall of the steel sheet slot 12 is indirectly provided with the steel sheet hook body 122. The steel sheet hook body 122 abuts against the bottom end surface of the steel sheet 2 to restrict the steel sheet 2 from disengaging from the bottom opening of the steel sheet slot 12; thereby enabling the steel sheet 2 and the steel sheet slot 12 to be detachably and fixedly connected. Usually, a waterproof cover 29 made of rubber or the like surrounds the steel sheet 2.

[0060] 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 a whole ring sector; an upward protrusion steel sheet connecting portion 32 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. The connecting rail mounting portion 33 is provided with a connecting rail connecting groove 331 with a T-shaped cross section.

[0061] The connecting rail 4 is flexible and is used to connect the wiping member 5 and the bridge bracket 3.

[0062] 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 a combination of a rubber strip 58 and a brush 59 sharing a wiping member mounting body 51 as described in Embodiment Seven later.

[0063] Both the connecting rail 4 and the wiping member 5 are profiles, that is, the cross section 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) is 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 that of the wiping member 5.

[0064] 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 both the bridge bracket connecting portion 43 and the wiping member connecting groove 451 are T-shaped.

[0065] 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.

[0066] The steel plate connecting part 32 is detachably connected to the steel sheet 2.

[0067] The bridge support connecting part 43 sequentially passes through the connecting rail connecting grooves 331 of each connecting rail mounting part 33, so that the connecting rail 4 is connected to the connecting rail mounting part 33. The brush member mounting body 51 passes through the brush member connecting groove 451, so that the brush member 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 brush member 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 part 32 enable the bridge support 3 to float, so that the connecting rail 4 and the brush member 5 can change their shapes according to the shape of the automobile window (such as different arcs, etc.), and can ensure that the brush member 5 fits the automobile window to ensure the brushing effect.

[0068] 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 arranged outside the following extension body 321, and the contact steel sheet protrusion 311 abuts against 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 or a trapezoid, etc. It can further increase the floating range of the bridge support 3 and ensure that the brush member 5 fits the automobile window.

[0069] 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 part 32 includes an extension body 321 and an anti - detachment structure 322 fixedly connected to the extension body 321. The extension body 321 passes through the bridge support opening 23, and the anti - detachment structure 322 is located above the steel sheet 2 and abuts against the steel sheet 2, so that the steel plate connecting part 32 is detachably connected to the steel sheet 2.

[0070] As one of the specific embodiments, the anti - detachment 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 both the steel plate connection part 32 and the bridge support opening 23 are 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 connection rail 4 and the brushing member 5 on the connection rail installation part 33 of the bridge support 3, and the bridge support 3 can be conveniently installed on the steel sheet 2. After the connection 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.

[0071] 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.

[0072] As one of the specific embodiments, a contact connection rail protrusion 332 is provided at the lower end of the connection rail installation part 33. It can make the connection rail 4 float relative to the connection rail installation part 33 to ensure that the brushing member 5 fits the car window.

[0073] 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 is snapped 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 brushing member 5, and the connecting rail 4, thereby restricting the brushing 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 brushing member 5, first insert the brushing member mounting body 51 into the brushing member connecting groove 451, such that the two coincide and are connected to each other in the length direction; then sequentially pass the bridge bracket connecting portion 43 through the connecting rail connecting groove 331 of the connecting rail mounting portion 33; and 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 brushing member 5, and the connecting rail 4. The brushing 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 section that for the connecting rail 4 and the brushing member 5 that are profiles, it is convenient to install the end buckle cap 6, and it can prevent the connecting rail 4 and the brushing member 5 from falling off or separating from each other.

[0074] 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.

[0075] 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 is snapped into the end buckle cap snap groove 34) is provided with an inclined surface (not marked in the drawings). The inner inclined surface of the end buckle cap snap 621 can play a guiding role, facilitating the end buckle cap snap 621 to be snapped 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.

[0076] As one of the specific embodiments, the end button cap guide rail 622 faces the end button cap buckle 621 and its thickness (the dimension in the direction towards the inner side of the end button cap side wall 62) is smaller than the thickness of the end button cap buckle 621. It is easy to understand that the end button cap guide groove 341 also faces the end button cap buckle groove 34. During the process of moving the end button cap 6 from the connecting rail mounting portion 33 to the steel plate connecting portion 32 so that the end button cap buckle 621 is snapped into the end button cap buckle groove 34, the end button cap buckle 621 first embeds into the end button cap guide groove 341 and moves along the end button cap guide groove 341. After the end button cap buckle 621 is snapped into the end button cap buckle groove 34, the end button cap guide rail 622 embeds into the end button cap guide groove 341, which can realize the pre-alignment of the end button cap buckle 621 and the end button cap buckle groove 34 for easy assembly, and can also ensure the connection strength between the end button cap 6 and the connecting rail mounting portion 33, and it is not easy for the two to shake up and down.

[0077] As one of the specific embodiments, on the inner side wall of the end button cap side wall 62, there is also a connecting rail fixing groove 623 located below the end button cap buckle 621, and the brush member connecting portion 45 is embedded into the connecting rail fixing groove 623. It can ensure the connection strength between the end button cap 6 and the connecting rail mounting portion 33, and it is not easy for the two to shake up and down.

[0078] As one of the specific embodiments, on the inner side wall of the end button cap end wall 61, there is a compression body 611; 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, which can ensure the connection strength after the assembly between the connecting rail 4 and the brush member 5.

[0079] Second and third embodiments. Refer to Figure 8 、 9 。

[0080] The improved wiper structure of the second and third embodiments is different from that of the first embodiment in that it is the bridge bracket 3.

[0081] 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 side wall of the elastic relief opening 324 of the extension body 321 that is exposed 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 button 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).

[0082] As shown Figure 9 in FIG. Figure 9 , the improved wiper structure of the third embodiment has a bridge bracket 3 made of a metal sheet and having 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 FIG. Figure 9 . The extension body 321 is provided with an elastic relief opening 324 by two metal sheets bent upward relative to the two opposite bridge bodies 31. 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 a spherical shape is intercepted by a plane) contact steel sheet protrusion 311 (since the thicknesses of the metal sheets are 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 vehicle 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.

[0083] Fourth, fifth, and sixth embodiments. Refer to Figure 16-26 .

[0084] It can be compared with Figure 14 and 15 the vehicle connecting bracket 1 of the first embodiment shown in FIG. 15 . The vehicle connecting bracket 1 of the first embodiment is an integrally formed structure made of plastic, and its vehicle connecting portion 11 is not replaceable. When it is necessary to change the vehicle connecting portion 11 along with the vehicle 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, since the vehicle connecting portion 11 is not replaceable, it is necessary to change the steel plate card slot 12 along with the vehicle connecting portion 11, and usually multiple molds need to be opened. Therefore, from the overall view of multiple different vehicle connecting brackets 1 (i.e., vehicle connecting brackets 1 of multiple models), the overall manufacturing cost of the vehicle connecting brackets 1 of multiple models is relatively high. It can be seen that there is room for improvement in the versatility of the vehicle connecting bracket 1 of the first embodiment.

[0085] The improved wiper structure of the fourth embodiment is different from that of the first embodiment in that the vehicle connecting bracket 1

[0086] The improved wiper structure of the fourth embodiment, the vehicle connecting bracket 1 includes a vehicle connecting member 13 and a steel plate card seat 14. The vehicle connecting portion 11 is arranged on the vehicle connecting member 13, and the steel plate card slot 12 is arranged on the steel plate card seat 14; the vehicle connecting member 13 and the steel plate card seat 14 are detachably and fixedly connected. It is possible to replace only the vehicle connecting member 13 as needed, which can improve the versatility and reduce the overall cost of the vehicle connecting brackets 1 of multiple models.

[0087] As one of the specific implementation manners, the vehicle connector 13 is linearly slidably connected with 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 with 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.

[0088] As one of the specific implementation manners, the top end of the clamping seat fixing hole 131 is exposed from the vehicle connector 13. During assembly, it can be confirmed that the clamping seat buckle body 141 is embedded in the clamping seat fixing hole 131 through the clamping seat fixing hole 131, which is beneficial to improving the quality.

[0089] As one of the specific implementation manners, 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 one 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, which is convenient for 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.

[0090] As one of the specific implementation manners, 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 connection reliability between the vehicle connector 13 and the steel plate clamping seat 14 after the wiper is assembled.

[0091] 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 greater 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 can be separated from the steel plate card holder 14; that is, the automotive connector 13 and the steel plate card holder 14 can be separated more conveniently after the wiper is assembled.

[0092] 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 on the side wall of the steel plate card holder 14. An inner stopper 154 and a clip buckle port 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 port 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.

[0093] 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.

[0094] 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.

[0095] As Figure 23 , 24As shown in the figure, for the improved wiper structure of the fifth embodiment, both ends of the elastic strip groove 132 are exposed from the side of the vehicle connector 13. There is at least one set of a card seat buckle body 141 and an elastic strip 142. One set of the card seat buckle body 141 and the elastic strip 142 are two that are mirror-symmetrical to each other (mirror-symmetrical about a plane perpendicular to the steel plate slot 12). It is easy to understand that the card seat fixing holes 131 and the elastic strip grooves 132 also correspond to the card seat buckle body 141 and the elastic strip 142, that is, there is at least one set of the card seat fixing holes 131 and the elastic strip grooves 132. One set of the card seat fixing holes 131 and the elastic strip grooves 132 are two that are mirror-symmetrical to each other. The sliding connection between the vehicle connector 13 and the steel plate card seat 14 is not limited to a single direction, which is more convenient. And after the card seat buckle body 141 is respectively snapped into the card seat fixing holes 131, it is difficult to separate the vehicle connector 13 from the steel plate card seat 14.

[0096] As Figure 23 shown in the figure, as one of the specific implementation manners, the clip buckle body 151 extends in a direction away from the steel plate slot 12 to form a toggle body 155 and a toggle groove 156. Bend the toggle body 155 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 detached from the steel plate card seat 14, which is convenient for rework or replacement of the steel sheet 2.

[0097] The improved wiper structure of the sixth embodiment is different from that of the fourth embodiment in the detachable connection manner between the vehicle connector 13 and the steel plate card seat 14.

[0098] For the improved wiper structure of the sixth embodiment, both the vehicle connector 13 and the steel plate card seat 14 are made of metal sheets. The vehicle connector 13 is provided with a bent connection ear 139, and the steel plate card seat 14 is provided with a bent connection ear groove 149. After the bent connection ear 139 passes through the bent connection ear groove 149 in a fitting manner and then bends and abuts against the steel plate card seat 14, the vehicle connector 13 is detachably connected to the steel plate card seat 14.

[0099] The seventh embodiment.

[0100] The improved wiper structure of the seventh embodiment is different from that of the first embodiment in the rubber strip connection rail 4 and the wiping member 5.

[0101] For the improved wiper structure of the seventh embodiment, the rubber strip connection rail 4 is provided with a plurality of wiping member connection grooves 451. The wiping member 5 includes a rubber strip 58 and / or a brush 59; the wiping member mounting bodies 51 of the rubber strip 58 and the brush 59 are respectively embedded in the wiping member connection grooves 451. Different wiping members 5 can be combined as needed, such as combining a wiping member 5 with a double rubber strip 58, such as a wiping member 5 with a brush 59 arranged inside the double rubber strip 58.
