The invention relates to the technical field of windshield wipers, in particular to a three-section windshield wiper which comprises a middle windshield wiper edge sleeve, a left windshield wiper edge sleeve is arranged on one side of the middle windshield wiper edge sleeve, and a right windshield wiper edge sleeve is arranged on the side, away from the left windshield wiper edge sleeve, of the middle windshield wiper edge sleeve. A left bone piece is arranged between the middle windshield wiper edge sleeve and the left windshield wiper edge sleeve, and a right bone piece is arranged between the middle windshield wiper edge sleeve and the right windshield wiper edge sleeve. A first clamping point is integrally formed on the inner wall of one side of the middle windshield wiper edge sleeve in an injection molding mode, and a second clamping point is integrally formed on the inner wall of the side, away from the first clamping point, of the middle windshield wiper edge sleeve in an injection molding mode. The clamping grooves in the two sides of the bone piece are clamped into the clamping points in the side sleeves, the clamping grooves are designed in the two sides of the bone piece, and therefore the bone piece can be suitable for the left side and the right side and can be installed only by rotating the direction; after improvement, a metal middle bone piece is reduced, and the bone pieces on the left side and the right side are made of plastic materials, so that parts are reduced, and the cost is reduced.
本发明涉及雨刷技术领域,具体为一种三段式雨刷,包括中部雨刷边套,所述中部雨刷边套的一侧设置有左侧雨刷边套,且中部雨刷边套远离左侧雨刷边套的一侧设置有右侧雨刷边套,所述中部雨刷边套与左侧雨刷边套之间设置有左部骨件,所述中部雨刷边套与右侧雨刷边套之间设置有右部骨件;所述中部雨刷边套一侧的内壁上一体式注塑有第一卡点,所述中部雨刷边套远离第一卡点一侧的内壁上一体式注塑有第二卡点。本发明骨件两侧的卡槽卡入边套内的卡点,骨件两侧都设计了卡槽,可使骨件适用于左右两侧,只要旋转方向即可安装;本发明改进后,减少了金属的中骨件,而左右两侧的骨件,采用塑料材质,减少部件,且降低成本。
