[0002] Cars are a common means of transportation in our daily lives, and windshield wipers are a very important part of cars, providing safety for driving in rainy weather. During use, windshield wipers are exposed to wind, sun and rain, and the wiper blades are prone to aging, resulting in water residue after being wiped off. Therefore, it is necessary to replace the wiper blades in time. The wiper blades are detachably connected to the mechanical control arm in front of the car's windshield. Traditionally, the installation of windshield wipers and mechanical control arms involves connecting multiple parts, which makes the assembly relatively complicated. Summary of the Invention

[0014] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.

[0015] Reference Figure 1 , Figure 2 A quick-assembly wiper includes a wiper blade 1, an assembly connector 2 mounted on the wiper blade 1, and a detachable swing arm 3 mounted on the assembly connector 2. The assembly connector 2 includes a rubber strip connector 21 snapped onto the wiper blade 1, a flip-up component 22 snapped onto the rubber strip connector 21, a limit clamping component 23 hinged to the end of the rubber strip connector 21, and a U-shaped clamping connector 31 provided at the end of the swing arm 3. The U-shaped clamping connector 31 is snapped onto the flip-up component 22, and the limit clamping component 23 is used to prevent the U-shaped clamping connector 31 from separating from the flip-up component 22. During the wiper installation process, first snap the wiper blade 1 onto the underside of the assembly connector 2, then rotate the limiting clamping part 23 on the rubber strip connector 21 by 90 degrees to expose the rotating part 22. At this time, snap the U-shaped clamping connector 31 at the end of the swing arm 3 onto the rotating part 22. Finally, fold the limiting clamping part 23 and the rubber strip connector 21 together. The limiting clamping part 23 limits the horizontal displacement of the U-shaped clamping connector 31, which can be used to prevent the U-shaped clamping connector 31 from separating from the rotating part 22, thus making the wiper installation convenient and quick. During the disassembly of the windshield wiper, the limiting clamping part 23 is rotated 90 degrees. At this time, the U-shaped clamping connector 31 can be quickly separated from the rotating part 22, making the windshield wiper disassembly convenient and quick, thereby improving the convenience of windshield wiper disassembly and installation.

[0016] The limiting clamping part 23 restricts the horizontal displacement of the U-shaped clamping connector 31, thereby making the installed wiper more stable and preventing it from falling off the swing arm 3, thus improving the stability of the connection; The U-shaped clip 31 is snapped onto the flip-up part 22, so that the wiper blade 1 and the rubber strip connecting seat 21 can be angularly offset on the swing arm 3, so that the wiper blade 1 can better fit the windshield, thus improving the wiping effect.

[0017] Reference Figure 1 , Figure 2A flipping shaft 24 is fixed on the rubber strip connector 21, and an R-shaped snap-fit ​​groove 25 is provided on the flipping part 22, which snaps onto the flipping shaft 24. During the installation of the flipping component 22, align the R-shaped snap-fit ​​groove 25 with the flipping shaft 24 and press the flipping component 22 so that the flipping component 22 can be quickly snapped onto the flipping shaft 24. Therefore, the assembly of the connecting seat 2 is convenient and quick.

[0018] Reference Figure 2 , Figure 3 , Figure 4 The flip-up part 22 is provided with a clamping terminal 221 at its end. The U-shaped connector 31 is clamped on the clamping terminal 221. The flip-up part 22 is provided with a locking channel 222 on its lower side. The U-shaped connector 31 passes through the locking channel 222. The flip-up part 22 is provided with a locking groove 223 on its upper side. After the U-shaped connector 31 is clamped with the flip-up part 22, the bottom of the U-shaped connector 31 is in contact with the clamping terminal 221, the lower side of the U-shaped connector 31 is inserted into the locking channel 222, and the upper side of the U-shaped connector 31 is clamped in the locking groove 223, thereby enhancing the stability of the connection between the U-shaped connector 31 and the flip-up part 22. After the U-shaped clip connector 31 is installed, the lower side of the U-shaped clip connector 31 is located under the flip shaft 24, so that the R-shaped clip groove 25 forms a closed structure, which can effectively prevent the flip part 22 from separating from the rubber strip connecting seat 21, thereby further improving the stability after the wiper is installed. The end of the U-shaped clip connector 31 is provided with a limiting protrusion 32. After the limiting protrusion 32 passes through the locking channel 222, it can form a snap-fit ​​structure with the locking channel 222, thereby further enhancing the stability of the wiper after installation.

[0019] Reference Figure 2 , Figure 5 , Figure 6 The limiting clamping component 23 is provided with a limiting strip 231, which limits the displacement of the U-shaped snap connector 31. A snap-fit ​​terminal 232 is provided on the lower side of the limiting clamping component 23. A locking groove 211 is provided on the rubber strip connecting seat 21, and a locking structure is formed between the locking groove 211 and the snap-fit ​​terminal 232.

[0020] After the limiting clamping part 23 and the rubber strip connecting seat 21 are folded, the snap-fit ​​terminal 232 snaps into the locking groove 211 to form a locking structure. The limiting strip 231 limits the displacement of the U-shaped snap-fit ​​connector 31, thereby forming a locking structure between the assembly connecting seat 2 and the swing arm 3, thus enhancing the stability of the structure after the wiper is installed.

[0021] Reference Figure 5 , Figure 6The limiting clamping member 23 has elastic displacement plates 233 on both sides, and the snap-fit ​​terminal 232 is fixed on the elastic displacement plate 233. By pressing the elastic displacement plate 233, the snap-fit ​​terminal 232 can be quickly separated from the locking groove 211, so that the limiting clamping member 23 can be flipped relative to the rubber strip connecting seat 21, thus making it easier to disassemble the wiper.

[0022] Reference Figure 7 , Figure 8 The rubber strip connector 21 has a convex connecting groove 212 on its lower side. The wiper blade 1 has a snap-fit ​​strip 11 fixed on its upper side that engages with the convex connecting groove 212. Locking protrusions 213 are fixed on both sides of the convex connecting groove 212. Locking plates 12 are fixed on both sides of the snap-fit ​​strip 11. The locking plates 12 engage with the locking protrusions 213. The snap-fit ​​strip 11 has a convex structure and snaps into the convex connecting groove 212. During the installation process, the locking plate 12 and the locking protrusion 213 are offset. Then, the snap-fit ​​strip 11 is pushed so that the locking plate 12 and the locking protrusion 213 overlap and snap together, thereby completing the installation of the wiper blade 1. Wiper blade 1 and rubber strip connector 21 can be easily disassembled and installed. When wiper blade 1 is severely worn, only wiper blade 1 can be replaced, thus saving costs.
