Description

Technical Field

[0001] The utility model relates to the technical field of windshield wipers, in particular to a windshield wiper for an automobile. Background Art

[0002] A windshield wiper is a tool used to clean the front glass of a motor vehicle to prevent rain and other dirt from affecting the vision.

[0003] Since the existing automobile wiper has an interface at the middle end of the wiper brush strip, which is then clamped with the clamping head at the front end of the wiper arm, the brush strip fits tightly against the automobile windshield. After long-term use, the wiper brush strip cannot fit effectively against the automobile windshield due to wear or other factors, resulting in poor windshield wiping effect and requiring repair or replacement. The service life is short, and during the replacement process, it is necessary to first move and stand up the wiper arm, so as to facilitate the operation of separating the clamping head at the front end of the wiper arm from the interface at the middle end of the wiper brush strip. After disassembling the wiper brush strip, the stood wiper arm is easy to fall down, and then the clamping head at the front end of the wiper arm is easy to hit the automobile windshield, damaging the automobile windshield and causing greater losses. Therefore, it is necessary to provide an automobile wiper to solve the above problems. Utility Model Content

[0031] The adjusting assembly 5 includes an adjusting screw 501 , which is rotatably disposed at the inner center of the mounting box 2 .

[0032] Among them, the adjustment component 5 also includes an upper plate 503, a lower plate 504 and a limiting slide bar 505. The upper plate 503 and the lower plate 504 are both arranged inside the installation box 2. The inner walls on both sides of the installation box 2 are provided with slide grooves 201. The upper plate 503 and the lower plate 504 are slidably connected with the slide grooves 201 through sliders. The upper end of the adjusting screw 501 passes through the upper wall of the installation box 2 and is fixedly provided with a knob 502. The upper plate 503 is threadedly connected with the adjusting screw 501. The center of the lower plate 504 is provided with a through hole. The lower end of the adjusting screw 501 passes through the through hole and is rotatably connected with the bottom surface of the installation box 2 through a bearing. The adjusting screw 501 does not contact the lower plate 504. By providing the installation box 2, it is convenient to install the adjustment component 5. By rotating the knob 502, the adjusting screw 501 can be effectively driven to rotate synchronously. Under the limiting action of the slider and the limiting slide bar 505, the upper plate 503 can be moved up and down in the vertical direction.

[0033] Among them, there are two limit slide bars 505, both of which pass through the upper plate 503 and the lower plate 504 and have their two ends connected to the upper and lower surfaces inside the installation box 2 respectively, and a buffer spring 506 is sleeved on the outer surface of the limit slide bar 505, the upper end of the buffer spring 506 is connected to the upper plate 503, and the lower end of the buffer spring 506 is connected to the lower plate 504, and a connecting column 507 is provided on the lower end surface of the lower plate 504 and on both sides of the adjusting screw 501. The lower end of the connecting column 507 passes through the lower wall of the installation box 2 and is fixedly connected to the base 3, and the connecting column 507 is slidably connected to the lower wall of the installation box 2. When the brush strip 4 cannot effectively fit the front windshield of the car due to wear, it moves downward through the upper plate 503, and the upper plate 503 pushes the lower plate 504 to move downward synchronously through the buffer spring 506, and then the lower plate 504 pushes the brush strip 4 to fit the front windshield of the car through the connecting column 507, and there is no need to replace the brush strip 4, thereby extending the service life of the brush strip 4.

[0034] Among them; a T-slot 301 is provided on the lower end surface of the holder 3, a T-slot 401 is fixedly provided on the middle end of the upper end surface of the brush strip 4, the T-slot 401 is clamped with the T-slot 301, a positioning hole is provided at the middle end of the T-slot 401, and a positioning pin 7 cooperating with the positioning hole is provided on the holder 3. By clamping the T-slot 401 into the T-slot 301 and inserting the positioning pin 7, the installation of the brush strip 4 is more convenient, and it is convenient for later disassembly and maintenance.

[0035] Wherein; side panels 302 are fixedly provided at the lower ends of both sides of the holder 3, mounting holes are provided at both ends of the side panels 302, and buffer members 6 are provided at both ends of the side panels 302 through the mounting holes. The buffer member 6 includes a mounting shaft 601, a cylindrical rubber block 602 and a limiting upper cover 603. The upper end of the mounting shaft 601 passes through the mounting hole and is threadedly connected to the limiting upper cover 603. The cylindrical rubber block 602 is hollow inside, and a through hole 604 is provided on the center of the bottom surface and the side wall of the cylindrical rubber block 602. When the erected wiper arm 1 falls down, the cylindrical rubber block 602 first contacts the front windshield of the car, and then the cylindrical rubber block 602 is squeezed and deformed, and the internal gas of the cylindrical rubber block 602 can be effectively discharged through the through hole 604. The force deformation of the cylindrical rubber block 602 can effectively buffer the force and avoid damage to the front windshield of the car.

[0036] Working principle: by inserting the T-shaped clip 401 into the T-shaped slot 301 and inserting the positioning pin 7, the installation of the brush strip 4 is more convenient and easy to disassemble and repair later. When the brush strip 4 cannot effectively fit the front windshield of the car due to wear, by turning the knob 502, the adjusting screw 501 can be effectively driven to rotate synchronously. Under the limiting action of the slider and the limiting slide bar 505, the upper plate 503 is moved downward in the vertical direction. The upper plate 503 pushes the lower plate 504 to move downward synchronously through the buffer spring 506, and then the lower plate 504 pushes the brush strip 4 to fit the front windshield of the car through the connecting column 507. There is no need to replace the brush strip 4, thereby extending the service life of the brush strip 4.

[0037] Furthermore, when the erected wiper arm 1 falls down, the cylindrical rubber block 602 first contacts the front windshield of the car, and then the cylindrical rubber block 602 is squeezed and deformed, and the internal gas of the cylindrical rubber block 602 can be effectively discharged through the through hole 604. The cylindrical rubber block 602 is deformed by force, which can effectively buffer the force and avoid damage to the front windshield of the car.
