Problems solved by technology

However, after the wiper is used for a long time, there will be wear and tear between the parts of the wiper arm, the spring of the wiper arm in a stretched state will undergo plastic deformation, and the durability of the wiper arm will also be reduced. The change of the pressing force between the window glass will make the wiping effect worse and worse. The pressing force of the existing wiper arm cannot be adjusted, and the effect of the hanging brush will become worse after long-term use, which will bring safety hazards to driving

Embodiment Construction

[0019] The wiper arm in the embodiment of the present invention will be further described below in conjunction with the accompanying drawings, specifically as follows:

[0020] The wiper arm 10 in the embodiment of the present invention is as figure 1 As shown, it includes an arm 12 , a coupling 16 , a spring 18 installed in the arm 12 and an adjustment device 20 . The link 16 is connected to one end (for example, the bottom end) of the arm 12 , and the arm 12 and the link 16 are hingedly connected, so the arm 12 can rotate around the hinge relative to the link 16 . The coupling piece 16 is provided with a hook-shaped holding portion 17 , and one end (eg, bottom end) of the spring 18 is connected to the holding portion 17 of the coupling piece 16 .

[0021] Such as figure 2 shown as figure 1 The partial structure of the wiper arm shown mainly shows the specific structure of the adjusting device 20 . The adjusting device 20 includes a pull ring 22 , a connecting sleeve 23 ...

Abstract

The invention discloses a wiper arm. The wiper arm comprises an arm part, a connecting piece and a spring mounted in the arm part, wherein one end of the spring is connected with the connecting piece; an adjusting device which comprises a pull ring, a screw rod, a threaded sleeve and an adjusting ring is further mounted in the arm part; the pull ring is connected with the other end of the spring; the screw rod with a threaded part formed thereon is connected with the pull ring; the threaded sleeve with an internally threaded hole formed therein is fixed on the arm part; the threaded part of the screw rod is in threaded fit with the internally threaded hole of the threaded sleeve; the adjusting ring is fixedly mounted on the screw rod. According to the wiper arm, the adjusting ring, the screw rod, the threaded sleeve and the pull ring together form the adjusting device, and the position of the screw rod in the threaded sleeve can be adjusted to enable the stretching amount of the spring to change so as to adjust the pressing force of the wiper arm.

Description

technical field [0001] The technical field of the invention relates to an automobile component, and in particular to a wiper arm. Background technique [0002] In order to ensure that the vehicle can travel safely in the rain, the wiper is an indispensable part, and the wiping effect of the wiper directly affects the normal driving of the vehicle. The pressing force between the wiper and the windshield glass is one of the important factors affecting the wiping effect, and only a proper pressing force can have a good wiping effect. The pressing force between the wiper and the windshield is mainly generated by the stretching of the spring on the wiper arm. However, after the wiper is used for a long time, there will be wear and tear between the parts of the wiper arm, the spring of the wiper arm in a stretched state will undergo plastic deformation, and the durability of the wiper arm will also decrease. The change of the pressing force between the window panes will make the...
