[0027] like Figure 1 and 2 As shown, the wiper arm assembly 10 includes a wiper arm shaft 100, which is internally provided with a liquid passage cavity 101, which is connected to the liquid passage pipe inside the vehicle. The wiper arm shaft 100 is a component of the wiper arm assembly 10, which mainly serves as a support, can fix the wiper blade on the windshield and realize the wiping action. The wiper arm shaft 100 is internally provided with a liquid passage cavity 101, which is connected to the liquid passage pipe inside the vehicle. The liquid passage cavity 101 is used to transmit water flow from the vehicle to ensure that the water flow can be evenly sprayed on the windshield. The wiper arm shaft 100 is internally provided with a liquid passage cavity 101, and the wiper arm shaft 100 and the liquid passage cavity 101 are integrated into a whole wiper arm assembly 10, which can simplify the manufacturing process and improve the reliability and stability of the system.

[0028] like Figure 2As shown, the liquid spraying assembly 20 includes: a nozzle 200 and a connecting pipe 201. The nozzle 200 is arranged on the scraper arm shaft 100, and the connecting pipe 201 is arranged in the liquid passage chamber 101. One end of the connecting pipe 201 is connected to the nozzle 200, and the other end of the connecting pipe 201 is connected to the liquid passage chamber 101. The nozzle 200 and the connecting pipe 201 are components of the liquid spraying assembly 20. The nozzle 200 can mainly spray water evenly on the windshield to help the wiper blade more effectively remove rainwater and dirt. The connecting pipe 201 can mainly transmit water from the vehicle to the nozzle 200 to ensure smooth flow of water. The nozzle 200 is arranged on the scraper arm shaft 100. The nozzle 200 is installed on the scraper arm shaft 100. The connecting pipe 201 is arranged in the liquid passage chamber 101. The liquid passage chamber 101 is provided with a flow pipe 201. One end of the connecting pipe 201 is connected to the nozzle 200, and the connecting pipe The other end of 201 is connected to the liquid passage chamber 101, which ensures that the water flow is transmitted from the vehicle through the liquid passage chamber 101 and the connecting pipe 201 to the nozzle 200, and finally evenly sprayed on the windshield. The connection between the liquid passage pipe inside the vehicle and the nozzle 200 outside the vehicle can be realized, and the water flow can be transported from the inside of the vehicle to the outside of the vehicle. No additional fixing structure is required to fix the nozzle 200, which is convenient for installation and can save space. In addition, the rotatable connecting pipe 201 can realize the movement of the nozzle 200, thereby ensuring that the sprayed water flow always remains above the wiper blade, avoiding the occurrence of dry scraping. Among them, the nozzle 200 has a ball head structure, which can be adjusted by the water flow.

[0029] Therefore, a liquid passage chamber 101 is provided inside the scraper arm shaft 100, and a connecting pipe 201 is provided in the liquid passage chamber 101. One end of the connecting pipe 201 is connected to the nozzle 200, and the other end of the connecting pipe 201 is connected to the liquid passage chamber 101. At this time, the connection between the liquid passage pipe inside the vehicle and the nozzle 200 outside the vehicle can be realized, and the transportation of water from inside the vehicle to outside the vehicle can be realized. No additional fixed structure is required to fix the nozzle 200. The installation is convenient and space can be saved. In addition, the nozzle 200 can be moved through the rotatable connecting pipe 201, which can ensure that the sprayed water flow always remains above the scraper blade to avoid dry scraping.

[0030] Specifically, if Figure 2 As shown, the wiper structure 1 further includes a sealing assembly 30, which is sealed between the outer wall of the connecting tube 201 and the inner wall of the liquid passage cavity 101. The sealing assembly 30 primarily serves to seal between the outer wall of the connecting tube 201 and the inner wall of the liquid passage cavity 101, thereby achieving a seal between the connecting tube 201 and the liquid passage cavity 101, thereby preventing water leakage.

[0031] Among them, Figure 2As shown, the sealing assembly 30 includes: a first sealing member 300 and a second sealing member 301. The first sealing member 300 is sleeved on the connecting tube 201, and the first sealing member 300 is sealed between the outer wall of the connecting tube 201 and the inner wall of the liquid cavity 101. The second sealing member 301 is sealed between the outer wall of the connecting tube 201 and the inner wall of the liquid cavity 101. The first seal 300 and the second seal 301 are components of the sealing assembly 30, and both can play a sealing role. The first seal 300 is sleeved on the connecting pipe 201, and the first seal 300 is sealed between the outer wall of the connecting pipe 201 and the inner wall of the liquid chamber 101. The connecting pipe 201 is provided with a first seal 300, and the first seal 300 can rotate with the rotation of the connecting pipe 201. The first seal 300 is sealed between the outer wall of the connecting pipe 201 and the inner wall of the liquid chamber 101. At this time, the sealing between the connecting pipe 201 and the liquid chamber 101 can be achieved, thereby preventing water leakage. The second seal 301 is sealed between the outer wall of the connecting pipe 201 and the inner wall of the liquid chamber 101, and can also achieve sealing between the connecting pipe 201 and the liquid chamber 101, thereby preventing water leakage.

[0032] In addition, if Figure 1 As shown, the liquid spray assembly 20 further includes a liquid inlet pipe 202, one end of which is in communication with the liquid passage cavity 101, and the other end of which is in communication with the in-vehicle liquid passage. The liquid inlet pipe 202 primarily serves to supply liquid. One end of the liquid inlet pipe 202 is in communication with the liquid passage cavity 101, and the other end of the liquid inlet pipe 202 is in communication with the in-vehicle liquid passage. The two ends of the liquid inlet pipe 202 are in communication with the liquid passage cavity 101 and the in-vehicle liquid passage, respectively, so that the liquid passage cavity 101 can be connected to the in-vehicle liquid passage.

[0033] Of course, if Figure 1 As shown, the wiper structure 1 further includes a mounting member 40, a wiper arm shaft 100 connected to one side of the mounting member 40, and a liquid inlet pipe 202 disposed on the other side of the mounting member 40. The mounting member 40 primarily serves as a mounting member. The mounting member 40 is a fixed structure that connects the entire wiper structure 1 to the vehicle body. The wiper arm shaft 100 is connected to one side of the mounting member 40, and the liquid inlet pipe 202 is disposed on the other side of the mounting member 40. The wiper arm shaft 100 and the liquid inlet pipe 202 are disposed on both sides of the mounting member 40, respectively. This ensures the compactness and functionality of the wiper structure 1.

[0034] Furthermore, if Figure 1As shown, the scraper arm assembly 10 also includes: a scraper arm 102, the scraper arm shaft 100 includes: a first section 103 and a second section 104, the first section 103 can rotate relative to the second section 104, the scraper arm 102 is fixed on the first section 103, and the second section 104 is fixed on the mounting member 40. The scraper arm 102 can drive the scraper blade along the windshield surface to remove rainwater and dirt. The first section 103 and the second section 104 are components of the scraper arm shaft 100. The first section 103 can rotate relative to the second section 104. The scraper arm 102 is fixed to the first section 103. The scraper arm 102 is fixed to the first section 103 and can rotate with the rotation of the first section 103, thereby driving the scraper blade along the windshield surface to remove rainwater and dirt. The second section 104 is fixed to the mounting member 40, thereby connecting the scraper arm shaft 100 to one side of the mounting member 40. The scraper arm 102 is a connecting structure that connects the scraper blade to the wiper structure 1. It contains a spring mechanism to provide a pressing force for the scraper blade. The scraper blade is a brush structure, including a metal spring and rubber. The spring provides support, and the friction between the rubber and the glass achieves the cleaning function.

[0035] In addition, Figure 2 As shown, the wiper arm 102 is provided with a relief opening on the wiper arm cover 105. The relief opening is arranged opposite to the water spraying direction of the nozzle 200. The relief opening mainly serves as a relief. The wiper arm cover 105 mainly protects the internal structure of the wiper arm 102 from external dust and dirt. The relief opening is arranged opposite to the water spraying direction of the nozzle 200, which ensures that the water flow can be sprayed smoothly onto the windshield while protecting other components of the wiper arm 102.

[0036] It should be noted that if Figure 2 As shown, the scraper arm shaft 100 is provided with a clamping hole 106, and the nozzle 200 is clamped at the clamping hole 106. The clamping hole 106 can be used to fix the nozzle 200, ensuring the stability of the nozzle 200 and the accuracy of the water spraying direction. The nozzle 200 is clamped at the clamping hole 106, which can simplify the installation and maintenance of the nozzle 200, while ensuring the stability of the nozzle 200 and the accuracy of the water spraying direction. It should be noted that the liquid inlet pipe 202 realizes the transportation of water from the inside of the vehicle to the outside of the vehicle through the scraper arm shaft 100, the connecting pipe 201 and the nozzle 200, and does not require an additional fixing structure to fix the nozzle 200. In this case, installation is convenient and space-saving.

[0037] In addition, if Figure 1 and Figure 2As shown, the wiper structure 1 further includes a third seal 50, which seals between the wiper arm shaft 100 and the vehicle's windshield. The third seal 50 primarily serves as a seal between the wiper arm shaft 100 and the vehicle's windshield. This ensures a tight seal between the wiper structure 1 and the windshield during use, preventing water and dirt from entering the system while also improving system stability and reliability.
