Description
Technical field
The utility model relates to vehicular spare parts field, is specifically related to a kind of lifting mode wiper arm.
Background technology
Vehicle wiper is the safety component of automobile, and wiper is mainly made up of rain shaving electrical machine, speed reduction gearing, commutation transport sector (swing arm, ball cover, connecting rod etc.), scraping arm, scraping blade etc.Be mainly used to sassafras and wipe sleet and dust that glass adheres to, ensure getting a clear view of chaufeur.
The principle of work of vehicle wiper is when rain shaving electrical machine works, crank is driven to move in a circle after being slowed down by drop-gear box, then drive rocking arm to move reciprocatingly by connecting rod, and rocking arm drive scraping arm, clearing edges does back and forth movement to remove rainwater, snow or the dust on glass.
The scraping arm of wiper of the prior art as shown in Figure 1, is made up of short scraping arm 4, long scraping arm 1, spring 2, rivet 3 four parts.Connected by rivet 3 between long scraping arm 1 and short scraping arm 4, long scraping arm 1 can carry out the rotation of certain angle around rivet 3, and provides restoring force and the thrust between rain shaving blade and shield glass by spring 2.
The shortcoming one of prior art: the lifting of long scraping blade needs artificial carrying out, and the hommization of operation is poor, especially lifts when carwash and falls when switching mutually between wiper arm, operating complicated.The shortcoming two of prior art: the thrust between rain shaving blade and shield glass mainly gives by spring, when causing power between the two not in the scope of designing requirement, the rigidity only having adjustment spring or the attitude adjusting long wiper arm carry out the thrust of rain shaving blade.
Utility model content
The purpose of this utility model improves the convenience of wiper arm lift adjustment, and the purpose of this utility model provides following technical scheme for this reason:
A kind of lifting mode wiper arm, comprise: long scraping arm, short scraping arm, motor, driving gear, ring gear and force snesor, control unit, described motor to be fixed on described short scraping arm and to drive described driving gear, described ring gear engages with described driving gear and drives described long scraping arm, the end of described long scraping arm has scraping blade installation portion, described force snesor is fixed on described scraping blade installation portion, and described force snesor is connected with described control unit with described motor.
Preferably, the width of described short scraping arm is greater than the width of described long scraping arm.
Preferably, above-mentioned lifting mode wiper arm also comprises angular transducer, and described angular transducer is arranged on described short scraping arm, and described angular transducer is connected with described control unit.
Preferably, described long scraping arm is rigidly fixed on the axle of described ring gear, and described ring gear is arranged on described short scraping arm by bearing, and described driving gear is arranged on described short scraping arm by bearing.
Preferably, described scraping blade installation portion is hook-shape structure.
Preferably, described short scraping arm has lightening hole.
Embodiment of the present utility model utilizes motor to drive driving gear, the mode of ring gear makes long scraping arm drive scraping blade towards the direction lifting away from vehicle glass or decline towards the direction pressing close to vehicle glass, and scraping blade and vehicle glass can be adjacent to force feedback to control unit by force snesor, contrasted according to the size of power and setting power by control unit, control motor to rotate guarantee and be adjacent to power and be in preset range, therefore the elevating control of scraping arm is simple and can prevent from scraping blade transition from compressing vehicle glass causing scraping arm to damage.
Further, the rotary angle signal of long scraping arm can be passed to control unit by angular transducer, is controlled the anglec of rotation of long scraping arm by control unit according to the size of angle, prevents long scraping arm lifting too high.
Further, short scraping arm has larger width and thus has larger intensity, motor, driving gear and ring gear, angular transducer is all arranged on the alerting ability that short scraping arm can ensure long scraping arm activity.

Detailed description of the invention
Referring to figs. 2 to Fig. 4, the lifting mode wiper arm in the present embodiment, comprising: long scraping arm 5, short scraping arm 6, motor 10, driving gear 9, ring gear 8 and force snesor 12, control unit (not shown), angular transducer 11.The end of long scraping arm 5 has the scraping blade installation portion 7 of hook-shape structure, and force snesor 12 is fixed on scraping blade installation portion 7.
The other end of long scraping arm 5 is connected with short scraping arm 6, the width that the width of short scraping arm 6 is greater than long scraping arm 5 makes short scraping arm 6 have larger intensity, both are at concrete connection mode: motor 10 is fixed on short scraping arm 6, long scraping arm 5 is rigidly fixed on the axle of ring gear 8, ring gear 8 is arranged on short scraping arm 6 by bearing, and driving gear 9 is arranged on short scraping arm 6 by bearing.Ring gear 8 engages with driving gear 9, and motor 10 drives driving gear 9, and drives long scraping arm 5 further by ring gear 8, thus makes scraping blade installation portion 7 towards the direction lifting away from vehicle glass or decline towards near the direction of vehicle glass.Angular transducer 11 is arranged on short scraping arm 6.Angular transducer 11, force snesor 12 are connected with control unit with motor 10.In the present embodiment, driving gear 9, motor 10 and ring gear 8, angular transducer 11 are installed on short scraping arm 6, and the advantage done like this is the alerting ability that can ensure long scraping arm 5 like this.Driving gear 9, ring gear 8, motor 10 and angular transducer 11 also can be arranged on long scraping arm 5, but this is by increasing the weight of long scraping arm 5, reduces its alerting ability, are not therefore preferred version.
Short scraping arm 6 has lightening hole for alleviating the weight of short scraping arm 6.
During work, motor 10 drives the driving gear 9 on short scraping arm 6 to rotate, and drives long scraping arm 5 to rotate, thus realize the lifting of scraping blade by ring gear 8.The angle signal of angular transducer 11 passes to control unit, is controlled the anglec of rotation of long scraping arm by control unit according to angular dimension.The force signal that is adjacent to of the scraping blade that force snesor 12 detects and vehicle glass feeds back to control unit, control unit contrasts according to the size and setting power that are adjacent to power, signal transmission to motor 10, control the rotation of motor 10 until the power that is adjacent to is in setting range.Therefore the wiper arm lift adjustment of the present embodiment is convenient, and can prevent the scraping blade of wiper arm from crossing far away or tension of fitting from vehicle glass.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to above embodiment and change, but do not leave essential idea of the present utility model and scope.
