[0002] The windshield wiper is an important accessory installed on the windshield. Its function is to sweep away rain, snow and dust that obstruct the line of sight on the windshield. Therefore, it plays an important role in driving safety. Windshield wipers generally include vacuum windshield wipers, electric windshield wipers, and windshield wipers with an electronic control unit. The electric windshield wiper is driven by an electric motor and generally consists of a wiper arm, a wiper blade assembly, a rubber wiper blade, a wiper blade support, a wiper blade holder, a wiper arm spindle, a windshield wiper base plate, an electric motor, a reduction mechanism, a drive rod system, a drive rod hinge, a windshield wiper switch, and a windshield wiper switch knob, etc. The electric windshield wiper is driven by an electric motor. The left and right wiper blades of the windshield wiper are pressed against the outer surface of the windshield by the wiper arms. The electric motor drives the reduction mechanism to rotate and makes a reciprocating motion through the drive rod system, driving the wiper arms and the wiper blades to swing left and right to wipe the windshield.

[0003] At the end position of the windshield wiper, a protective head is usually installed to protect and limit the rubber strip and the end of the windshield wiper. The existing protective heads are directly bonded with glue. Such a structural setting is rather laborious during later disassembly and assembly and needs to be improved. Summary of the Invention

[0005] The purpose of the utility model can be realized by the following technical solutions: an improved windshield wiper structure, including a swing arm rod body, a protective head, a rubber strip body, a reinforcing rod, and a fixing seat. A protective head is installed at the end position of the swing arm rod body. A fixing seat is arranged inside the protective head. The end of the swing arm rod body is fixed inside the fixing seat. A rubber strip fixing groove is opened at the middle position on the side of the swing arm rod body. The rubber strip body is installed inside the rubber strip fixing groove, and the bottom of the rubber strip body is stuck inside the rubber strip fixing groove. Reinforcing cavities are arranged on both sides of the rubber strip fixing groove, and a reinforcing rod is arranged inside the reinforcing cavity.

[0006] In the above-mentioned improved windshield wiper structure, guiding hole positions are arranged on both sides inside the fixing seat, and clamping blocks are arranged inside the guiding hole positions.

[0007] In the above-mentioned improved windshield wiper structure, a limiting groove is opened at the end of the reinforcing rod, and the clamping block is stuck inside the limiting groove.

[0008] In the above-mentioned improved windshield wiper structure, a rubber strip guide groove is formed on the surface of the protective head, and one end of the rubber strip body is placed inside the rubber strip guide groove. The rubber strip body of the present application is a publicly available windshield wiper rubber strip, which is mainly installed on the inner side of the windshield wiper. When the windshield wiper swings, stains and rainwater on the glass are scraped off.

[0009] In the above-mentioned improved windshield wiper structure, side frames are provided on both sides of the bottom end of the protective head, and foot pads are installed inside the side frames.

[0010] Compared with the prior art, the advantages of the improved windshield wiper structure of the present utility model are as follows: in the present application, a strengthening inner cavity is formed inside the swing arm rod body, and two symmetrical strengthening rod structures are arranged inside the strengthening inner cavity. The support strength of the entire swing arm rod body can be greatly improved through the strengthening rods, the swing arm rod body has higher strength and is not easily broken. At the same time, a limiting groove is formed at the end of the strengthening rod, and a fixing seat with a clamping block is arranged inside the protective head. When installing the protective head, the swing arm rod body with the rubber strip is directly inserted into the protective head, and one end of the two strengthening rods is placed inside the fixing seat, so that the clamping block is clamped into the limiting groove, thus completing the fixing and limiting between the fixing seat and the strengthening rod. In this way, the installation of the protective head can be completed, and the entire installation process is simple and efficient and not easily detached. BRIEF DESCRIPTION OF THE DRAWINGS
