Description

Windshield wiper automatic lifting device

Technical field

This utility model relates to a kind of windshield wiper automatic lifting device, a kind of windshield wiper automatic lifting device controlled by proximity Hall switch.

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.

But its rain brush life-span of the love car of each car owner may and differ, derive from good use habit permanent service life, such as: using rain brush when; must not dry scrape; the most just can first spray bath of glass to 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 rain brush service life.Especially when summer, the high temperature of the sun is easy to make rubber softening, deformation, follows the string.On the one hand so we to avoid automobile to be exposed to the sun under burning sun as far as possible, on the other hand, after stopping, rain brush is holded up every time, it is to avoid rain brush always with glass gluing.

Summary of the invention

For above-mentioned situation, the purpose of this utility model is to provide a kind of windshield wiper automatic lifting device, after stopping, it is possible to holded up by rain brush every time, it is to avoid fit with windshield.

For reaching above-mentioned purpose, this utility model provides a kind of windshield wiper automatic lifting device, is installed between windscreen wiper and wiper blade, and this windshield wiper automatic lifting device includes:

One motor, connects this wiper blade, and this motor is powered by automobile power source, and has a proximity Hall switch, and this proximity Hall switch is controlled break-make by the Magnet in car and its distance；

One rotating shaft, is connected to this motor, and rotates after motor is energized；

One eccentric, is connected with this rotating shaft, and when this rotating shaft rotates, the distance between this eccentric outer rim and windshield constantly changes, and when keeping gap between the outer rim and windshield of this eccentric, the middle part of this wiper blade fits on windshield；And when the outer rim of this eccentric supports windshield, and the distance of this rotating shaft and windshield more than the distance of this rotating shaft and this wiper blade outer rim time, the middle part of this wiper blade departs from windshield.

Compared to prior art, windshield wiper automatic lifting device of the present utility model is controlled proximity Hall switch by the Magnet in car and controls the rotation of motor, come the position of control eccentric, and then control the pertinent relation of wiper blade and windshield, when needs use wiper blade, the middle part controlling wiper blade contacts with windshield, and when not using rain brush, the middle part controlling wiper blade disengages with windshield；Thus the service life of wiper blade can be extended.

[accompanying drawing explanation]

Fig. 1 is the schematic diagram of this utility model windshield wiper automatic lifting device；

Fig. 2 is the use state diagram that the middle part of this utility model windshield wiper automatic lifting device fits in windshield；

Fig. 3 is that Fig. 2 is in the state diagram at another visual angle；

Fig. 4 is the use state diagram that this utility model windshield wiper automatic lifting device controls the middle part disengaging windshield of wiper blade；

Fig. 5 is that Fig. 4 is in the state diagram at another visual angle.

[detailed description of the invention]

A kind of windshield wiper automatic lifting device 30 of the present utility model, is installed between windscreen wiper (not shown) and wiper blade 20, including motor 32, rotating shaft 31 and eccentric 33.

Refer to shown in Fig. 1, this motor 32 is connected to this wiper blade 20, in the present embodiment, the power line of this motor 32 and ground wire are connected to power supply in car, powered by automobile power source, this motor 32 also has a proximity Hall switch 4, and this proximity Hall switch 4 is controlled break-make by the Magnet 5 in car with its distance；

This rotating shaft 31 is connected to this motor 32, and rotates after motor 32 is energized；

Refer to shown in Fig. 2-5, this eccentric 33 is connected with this rotating shaft 31, and this rotating shaft 31 is when rotating, distance between this eccentric 33 outer rim and windshield 10 constantly changes, when keeping gap between the outer rim and windshield 10 of this eccentric 33, the middle part of this wiper blade 20 fits on windshield 10；And when the outer rim of this eccentric 33 supports windshield 10, and the distance of this rotating shaft 31 and windshield 10 more than the distance of this rotating shaft 31 and this wiper blade 20 outer rim time, the middle part of this wiper blade 20 departs from windshield 10.

Then, after user stops, by this Magnet 5 in car near this proximity Hall switch 4, work controlling this motor 32, this rotating shaft 31 starts to rotate, and this eccentric 33 starts to lift this rain brush after rotating to an angle, after being lifted by this rain brush completely, by this Magnet 5 away from this proximity Hall switch 4, stop controlling this motor 32.Before user starts up the car, by this Magnet 5 in car near this proximity Hall switch 4, control this motor 32 to work, this rotating shaft 31 starts to rotate, this eccentric 33 starts to put down this rain brush, after putting down completely, by this Magnet 5 away from this proximity Hall switch 4, stop controlling this motor 32, the most really can reach the purpose of this utility model.

Above in conjunction with accompanying drawing, detailed description of the invention of the present utility model and embodiment are elaborated, but can not with restriction scope of the present utility model, the impartial modification and transformation made in this utility model claim, all should belong in this utility model the scope of the claims.
