Problems solved by technology

However, it is found through observation that the deflector in the existing windshield wiper is usually integrally injection molded, and the deflector has a pulling force towards the opposite direction of the windshield to the elastic steel sheet, and the pulling force gradually increases after long-term use, so that the elastic steel sheet The elastic failure of the blade is accelerated, thereby shortening the service life of the wiper

[0020] Such as Figure 1 to Figure 2 As shown, it is the first embodiment of a hard shell wiper of the present invention, the wiper includes a wiper rubber strip 1; The wiper rubber strip 1 is clamped between the two memory steel sheets 2; a deflector 3, and the two memory steel sheets 2 are inserted in the deflector 3; a wiper arm connector 4, the wiper arm connector 4 is installed on the deflector The middle part of the deflector 3 ; wherein, the upper or lower part of the deflector 3 is provided with a plurality of notch grooves 31 equidistantly along the length direction of the deflector 3 .

[0021] Such as image 3 As shown, it is the second embodiment of a hard-shell wiper of the present invention. The difference between the second embodiment and the first embodiment is that in this embodiment, the cutout groove 31 on the deflector 3 is arranged on the deflector. The upper part of flow plate 3.

[0022] The key point of the present invention is that the deflector 3 i...

Abstract

The invention discloses a hard-shell windshield wiper. The windshield wiper comprises a windshield wiper rubber strip; two memory steel sheets which are inserted into the two sides of the windshield wiper rubber strip respectively, and the windshield wiper rubber strip is clamped between the two memory steel sheets; a guide plate, wherein the two memory steel sheets are inserted into the guide plate; a windshield wiper arm connector which is mounted in the middle of the flow guide plate; and a plurality of notch grooves which are formed in the upper portion or the lower portion of the flow guide plate at equal intervals in the length direction of the flow guide plate. The guide plate is provided with the notch groove, the flexibility of the guide plate is greatly improved, and the guide plate can be naturally bent and sleeved on the memory steel sheet in a manner of being matched with the memory steel sheet, so that the tensile force of the guide plate on the memory steel sheet in the direction opposite to the windshield is greatly reduced, and the elastic failure acceleration of the memory steel sheet caused by the tensile force is avoided; therefore, the service life of the windshield wiper is prolonged.

Description

technical field [0001] The invention relates to the technical field of wipers, in particular to a hard shell wiper. Background technique [0002] Wipers are usually used on the windshield to remove rainwater or other debris on the windshield. [0003] Existing wipers usually include wiper arm connectors, deflectors, elastic steel sheets and wiper rubber strips; during assembly, the elastic steel sheets clamp the wiper rubber strips and are installed in the deflector; the wiper arm connectors are installed on the middle of deflector. During use, the wiper is installed on the wiper arm through the wiper arm connector, and is pressed against the windshield, and the windshield is cleaned by the wiper rubber strip under the drive of the wiper arm. [0004] When the wiper is working, it mainly relies on the elastic force generated by the elastic steel sheet towards the windshield to press the wiper rubber strip against the windshield, so as to ensure that the wiper can work effe...
