Problems solved by technology

[0004] The problem with this wiper protection device is that although the wiper arm can be lifted, it must be pre-positioned and debugged before use so that the support platform and the support can cooperate with each other. There are many inconveniences during installation, and the matching method is single. Angle and lift position are limited, inconvenient to adjust, poor controllability, unable to fully protect the wiper
And be arranged on the support platform with inclined surface on the front windshield glass easily influence the driver's line of sight, be unfavorable for driving safety

Embodiment 1

[0025] refer to figure 1 , a wiper arm lifting device, which includes a signal collector 10, a controller 11, and an electric drive mechanism 12 and an actuator 13 arranged on a wiper arm 5. The signal collector 10 is used to collect the wiper switch signal and the swing position signal of the wiper arm as the status signal of the wiper, and output it to the controller 11, and the controller 11 is used to control the electric drive mechanism 12 to drive the actuator 13 on the wiper arm 5 When approaching the reverse position, to the first angle θ 1 Raise the wiper arm 5 and lower the wiper arm 5 after reaching the reverse position.

[0026] refer to figure 2 and image 3 One end of the wiper arm seat 6 is fixed on the end of the wiper motor drive shaft, the other end is hinged with the wiper arm 5, driven by the wiper motor, it swings around the drive shaft, and there is a wiper on the free end of the wiper arm 5. Sheet rubber strip 14, the bottom of wiper blade rubber st...

Embodiment 2

[0038] refer to Figure 9 , a lifting device for a wiper arm according to this embodiment, which includes a signal collector 10 , a controller 11 , and an electric drive mechanism 12 and an actuator 13 arranged on the wiper arm 5 . The signal collector 10 is used to collect the ignition switch signal as the wiper status signal, and output it to the controller 111. The controller 11 is used to control the electric drive mechanism 12 to drive the actuator 13, and lift the wiper arm 5 to second angle θ 2 ; Lower the wiper arm 5 when the ignition is switched on.

[0039] The electric drive mechanism and actuator in this embodiment are the same as those in Embodiment 1. The controller 11 can control the motor 1 to rotate in the forward direction, driving the worm 2 to rotate, the turbine 3 to follow, and the pressure arm 4 to press on the wiper arm seat 6 to apply force downward. Under the action of the reaction force, as Figure 4 As shown, the wiper arm 5 is lifted up by an an...

Embodiment 3

[0048] Referring to FIG. 111 , a lifting device for a wiper arm includes a signal collector 10 , a controller 11 , and an electric drive mechanism 12 and an actuator 13 arranged on the wiper arm 5 . The signal collector 10 is used to collect the wiper switch signal, the wiper arm swing position signal and the ignition switch signal as the wiper status signal, and output it to the controller 11, and the controller 111 is used to control the electric drive mechanism 12 to drive the actuator 13, When the wiper arm 5 swings towards the reverse position, it will move toward the first angle θ 1 Raise the wiper arm 5 to the first angle θ when it reaches the reverse position 1 , then lower the wiper arm 5, and lift the wiper arm 5 to the second angle θ when the ignition switch is turned off 2 , when the ignition switch is turned on, the wiper arm 5 is lowered; the first angle θ 1 less than the second angle θ 2 .

[0049] Since the windshield wiper of the vehicle has multiple state...

Abstract

The invention discloses a lifting device of a screenwiper arm. The lifting device comprises a signal acquisition device, a controller and an electric drive mechanism and an actuating mechanism arranged on the screenwiper arm, wherein the signal acquisition device is used for acquiring a state signal of a screenwiper and outputting the state signal into the controller; and the controller is used for judging the state of the screenwiper and controlling the electric drive mechanism to drive the actuating mechanism to lift or descend the screenwiper arm. A controlling method comprises: through acquisition of the state signal of the screenwiper, the lifting and descending of the screenwiper arm by the actuating mechanism are controlled. The lifting device has the advantages that the lifting device can use the structure of the prior screenwiper, directly mount the drive mechanism and the actuating mechanism on the screenwiper arm, is easy to modify and is flexible to control the lifting and descending of the screenwiper arm; and through the detection of the state of the screenwiper, the lifting device controls the lifting and descending of the screenwiper arm according to the state of the screenwiper, meets the protective requirements of different screenwipers, can lift the screenwiper arm when the screenwiper is stopped and solve the problem of aging due to the fact that a wiping rubber strip is contacted with windshield glass for a long time and is heated or frozen.

Description

technical field [0001] The invention relates to a protection device and method for a wiper used in a vehicle, in particular to a lifting device for a wiper arm and a control method thereof. Background technique [0002] In order to scrape off the rain on the front windshield of the car, the car wiper usually acts on the wiper arm through an elastic element, and presses the scraper rubber strip on the wiper arm against the windshield. The rubber strip can easily absorb the heat of the windshield glass, and it is easily affected by freezing in the cold season. It is exposed to the sun and rain, expands and contracts when heated, and the rubber strip of the scraper is in a compressed state for a long time, which can easily accelerate the aging of the rubber strip and reduce the its service life. [0003] The Japanese Laid-Open Patent Gazette with the publication number P2001-138871A discloses a protective device for wipers. A support platform with an inclined surface is provid...
