Description
Technical field
This utility model relates to a kind of windshield wiper automatic lifting device, a kind of windshield wiper automatic lifting device extending rain brush service life.
Background technology
Good rain brush must possess the features such as heat-resisting, cold-resistant, acid and alkali-resistance, anticorrosive, windshield of fitting, low noise, water-repellancy are strong, matter soft not scratch windshield.For guaranteeing the good visual field, usual rain brush needs to change once for about 1 year.When checking, rain brush can be pulled up by we, touches with in finger wiper rubber after the cleaning, and the elasticity of check whether there is damage and rubber tree leaf how.If blade aging, hardening, crackle occur, then Wiper blade is accomplished by changing.
Then need during Wiper blade hardening to change.When using when raining very heavily, rain brush sensation is pretty good, when starting rain brush when spotting, can find that rain brush leaves the vestige of wiping inequality on glass surface, have influence on your visual field, this shows that rain brush hardens, some situation, and when dataller makees like rain, glass surface is that vaporific, glass surface is thin globule shape, produces striped or On Local Fuzzy, this is due to oil film, the dirty or impact of car wax, as long as windshield and Wiper blade being cleaned up the most permissible.
The service life of anything will form good use habit.Using rain brush when, dry must not scrape, the most just can first spray bath of glass and open again, so not only contribute to protect glass, be also beneficial to protect rain brush.When automobile long-time no time, the film of rain brush can be made to be separated from each other with windshield with little batten pad under rain brush, be conducive to extend wiper blade service life.
When in summer, the high temperature of the sun is easy to make rubber softening, deformation, follows the string.So we to avoid automobile to be exposed to the sun under burning sun as far as possible.It addition, rain brush is holded up after stop every time, it is to avoid rain brush always with glass gluing.
It is not provided with windshield wiper automatic lifting device on existing automobile, is unfavorable for extending the service life of wiper blade.
Summary of the invention
Main purpose of the present utility model is to provide a kind of windshield wiper automatic lifting device extending rain brush service life.
This utility model provides a kind of windshield wiper automatic lifting device, and it is installed between windscreen wiper and wiper blade；And described windshield wiper automatic lifting device includes:
Rotating shaft, it is connected to windscreen wiper；
Stepper motor, it is connected between rotating shaft and wiper blade, and stepper motor is controlled on-off control stepper motor in being powered by automobile power source and passing through automobile and rotates, and the rotation of stepper motor drives rotating shaft to rotate simultaneously；
Eccentric, it is connected to rotating shaft, and when described rotating shaft rotates, the distance between eccentric and vehicle glass constantly changes, and when keeping gap between the outer rim and vehicle glass of eccentric, the middle part of wiper blade fits on vehicle glass；And when the outer rim of eccentric supports vehicle glass, and the distance of rotating shaft and vehicle glass more than the distance of rotating shaft and wiper blade outer rim time, the middle part of wiper blade departs from vehicle glass.
Especially, one end of described stepper motor is connected to fixed voltage end, and the other end of described stepper motor is connected to variable-resistance sliding end, and when the voltage of fixed voltage end is more than the voltage of variable-resistance sliding end, stepper motor carries out first direction rotation；When the voltage of fixed voltage end is less than the voltage of variable-resistance sliding end, stepper motor carries out second direction rotation；When the voltage of fixed voltage end is equal to the voltage of variable-resistance sliding end, stepper motor is static.
Compared with prior art, this utility model windshield wiper automatic lifting device turns the position of eccentric by the Spin Control controlling stepper motor, and then control the middle part of wiper blade and the matching relationship of vehicle glass, when using rain brush, the middle part controlling wiper blade contacts with vehicle glass, and when not using rain brush, the middle part controlling wiper blade disengages with vehicle glass；Thus the service life of wiper blade can be extended.
[accompanying drawing explanation]
Fig. 1 is that this utility model windshield wiper automatic lifting device controls the middle part of wiper blade and fits in the use state diagram of vehicle glass.
Fig. 2 is that Fig. 1 is in the state diagram at another visual angle.
Fig. 3 is the use state diagram that this utility model windshield wiper automatic lifting device controls the middle part disengaging vehicle glass of wiper blade.
Fig. 4 is that Fig. 3 is in the state diagram at another visual angle.
[detailed description of the invention]
Referring to shown in Fig. 1-4, this utility model provides a kind of windshield wiper automatic lifting device 30, and it is installed between windscreen wiper (not shown) and wiper blade 20；And described windshield wiper automatic lifting device includes:
Rotating shaft 31, it is connected to windscreen wiper；
Stepper motor 32, it is connected between rotating shaft 31 and wiper blade 20, and stepper motor 32 controls on-off control stepper motor 32 in being powered by automobile power source and passed through automobile and rotates, and the rotation of stepper motor 32 drives rotating shaft to rotate simultaneously；
Eccentric 33, it is connected to rotating shaft 31, and when described rotating shaft 31 rotates, the distance between eccentric 33 and vehicle glass 10 constantly changes, and when keeping gap between the outer rim and vehicle glass 10 of eccentric 33, the middle part of wiper blade 20 fits on vehicle glass 10；And when the outer rim of eccentric 33 supports vehicle glass 10, and the distance of rotating shaft 31 and vehicle glass 10 more than the distance of rotating shaft 31 and wiper blade 20 outer rim time, the middle part of wiper blade 20 departs from vehicle glass 10.
In the present embodiment, the power line of stepper motor 32 and ground wire can be connected to power supply in car, the rotation of stepper motor 32 is by controlling on-off control in automobile, the middle part of the visual wiper blade of user 20 operation-control switch stepper motor 32 rotation are to the position being suitable for.
