AI Technical Summary
Existing covers with increased high-speed performance are often assembled from under the scraping arm, which makes the assembly structure difficult to see and often fail to assemble.
A connection structure between the connecting member of the wiper and the scraper arm is designed. By setting a shaft hole on both side walls of the connecting member body, and a tongue and protrusion are provided at one end of the connecting member body, combined with the rotating shaft structure and the sinking groove design, the visibility and stable connection between the scraper arm and the connecting member is achieved.
Through this design, workers can easily see whether the scraping arm and the connector are assembled in place, which significantly reduces the problem of assembly parts in place.

[0003] The technical problem to be solved by the utility model is to provide a connection structure between a wiper blade connector and a wiper arm in view of the problem that the existing cover with increased high-speed performance is mostly assembled from the bottom of the wiper arm, making the assembly structure difficult to see and often resulting in improper assembly.
[0004] The technical problem to be solved by the utility model can be achieved through the following technical solutions:
[0005] The cam is an axially coupled machine which is adapted to engage the at least one axial hole of the wiper blade, wherein the at least one axial hole is engaged with the at least one axial hole of the wiper blade fixing seat, and the cam is connected to the at least one axial hole of the wiper blade fixing seat by a screw thread.
[0006] In a preferred embodiment of the utility model, a slot is respectively provided between the two side surfaces of the protrusion and the two side surfaces of the connecting member body, and an insertion wall is respectively provided on the two side walls at the upper end of the scraper arm inserted into the connecting member. During installation, the insertion wall is inserted into the corresponding slot.
[0007] In a preferred embodiment of the utility model, a flange is respectively provided on the two side surfaces of the scraper arm near the insertion wall, and during installation, the flange is hooked on the bottom of the connector body.
[0008] Due to the adoption of the above technical solution, the utility model can facilitate workers to connect in a visual manner, which is helpful to reduce the problem of the assembly part being in place. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.
[0014] See also Figures 1 to 4 , a connection structure of a connecting member and a wiper arm of a wiper shown in the figure includes a connecting member 100 and a wiper arm 200.
[0015] The connector 100 has a connector body 110, and an axial hole 111a is respectively provided on the two side walls 111 of the connector body 110. The axial hole 111a is sleeved on the shaft 311 on the two side surfaces 310 of the scraper fixing seat 300, so that the connector 100 is hinged on the scraper fixing seat. The scraper fixing seat 300 is used to fix and install the scraper 400.
[0016] A spring tongue 112 is provided at one end of the connector body 110 not wrapped by the scraper arm 200. The spring tongue 112 is connected to the connector body 110 via a shaft structure 113. The shaft structure 113 is located between the shaft hole 111a and the end of the spring tongue 112 away from the shaft hole 111a.
[0017] The utility model is characterized in that: a protrusion 114 protruding from the connector body 110 is provided at one end of the connector body 110 which is not wrapped by the scraper arm 200, a recess 114a is provided on the top surface of the protrusion 114, and the recess 114a is open toward one side of the rotating shaft structure 113; the spring tongue 112 is located in the recess 114a.
[0018] A plane 220 protruding from the top surface 210 of the scraper arm 200 is provided on one end of the scraper arm 200 inserted into the connecting piece 100, and a hole 221 adapted to the spring tongue 112 is provided on the plane 220; during installation, the plane 220 is inserted into the sink groove 114a, and the spring tongue 112 moves up and down and springs into the hole 221.
[0019] A slot 115 is provided between the two side surfaces of the protrusion 114 and the two side surfaces 111 of the connector body 110, and an insertion wall 231 is provided on the two side walls 230 of the scraper arm 200 at the upper end of the connector 100. When installing, the insertion wall 231 is inserted into the corresponding slot 115. A flange 232 is provided on the two side surfaces 230 of the scraper arm 200 near the insertion wall 231. When installing, the flange 232 is hooked on the bottom of the connector body 110.
[0020] See especially Figure 3 During the specific assembly, the assembler can see whether the scraper arm 200 and the connecting member 100 are assembled in place, which is helpful to reduce the problem of the assembly part being in place.
