Abstract

A wiper protector consists of a hull, which is arranged on an automobile wiper arm and a motor, a relay, a reduction gear cluster, a rack and two limit switches arranged in the hull. The output end of the motor is equipped with a worm and the relay is controlled by an automobile start switch and controls the starting and turning of the motor; the input and output ends of the reduction gear cluster are separately meshed with the motor worm and the rack; one end of the rack is penetrated through the hull and extended to the automobile windshield and the extended end is equipped with an adjusting screw whose retracting range can be adjusted and locked by a screw cap; two ends of the rack in the hull are separately equipped with heaves which are matched with the limit switches; the two limit switches are separately arranged on the upper and lower sides in the hull and send the signal of controlling the motor operation to the relay. The utility model is characterized by simple structure, convenient operation and accurate action and can ensure the wiper is separated from the windshield surface when the automobile is parked to reduce the contact time.

Description

The rain brush protector

Technical field

The utility model relates to a kind of rain brush protector, particularly relates to a kind of automobile starting switch of utilizing and controls the rain brush protector that can break away from Windshield when rain brush does not use.

Background technology

For safeguarding traffic safety, all be provided with rain brush on the Windshield of automobile, to clean Windshield at any time, keep the clear of the driving visual field.But general rain brush is all for a long time attached on the Windshield, and is subjected to for a long time exposing to the weather and the etch of exhaust gases, thus be easy to take place to go bad, scratch or elastic fatigue, thus shorten its service life.For this reason, so-called rain brush protector occurred, its effect is when stopping, and makes rain brush disengaging Windshield and avoids Long contact time, thereby reduce the loss of rain brush, prolongs its service life.But the structure more complicated of existing rain brush protector and be easy to et out of order is so influence car owner's installation wish.In addition, existing rain brush protector adopts manually control, not only operates cumbersomely, and is easy to make the car owner to forget operation, thereby the rain brush protector is performed practically no function.

Summary of the invention

The purpose of this utility model promptly be to provide a kind of simple in structure, control convenient and move accurate rain brush protector.

To achieve these goals, the utility model utilizes housing and is installed in housing interior motor, relay, train of reduction gears, tooth bar and two limit switches and constitutes a kind of rain brush protector.Housing is installed on the Wiper arm of automobile; The mouth of motor is provided with a worm screw, and relay is by the startup of automobile starting switch control and control motor and turn to; The input end of train of reduction gears and motor output end worm mesh, its mouth then is meshed with tooth bar; One end of tooth bar passes housing and stretches to windshield, and its protrude end is provided with the plus-minus screw that can adjust flexible distance and utilizes fixed by nut, and the simple and unadorned two ends of the tooth in housing are respectively equipped with two salient points of working in coordination with limit switch; Two limit switches are separately positioned on the both sides up and down of housing and to the signal of relay transmitting control motor operations.

Based on above structure, the utility model can make rain brush leave Windshield and reduce contact time when parking of automobile; When automobile starting, rain brush promptly attaches on the Windshield and carries out work.

Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model rain brush protector.

Fig. 1 is the scheme drawing of the utility model at the parking of automobile state.

Fig. 2 is the scheme drawing of the utility model at running condition of automobile.

Fig. 3 is the action scheme drawing of the utility model at the parking of automobile state.

Fig. 4 is the action scheme drawing of the utility model at running condition of automobile.

The specific embodiment

As depicted in figs. 1 and 2, the utility model rain brush protector 1 is installed on the Wiper arm 21 and utilizes automobile starting switch control.Advance when automobile is in dead ship condition, but rain brush protector 1 pushing tow rain brush 2 breaks away from Windshield 3 surfaces; When automobile starting, rain brush 2 is attached on the Windshield 3 and the function of performance rain brush.

As shown in Figure 3, Figure 4, the utility model rain brush protector has a housing 11, is provided with a motor 12 in it, and this motor 12 is by relay 13 controls, and relay 13 then is subjected to automobile starting switch control and the startup and the rotation direction of decision motor 12.The mouth of motor 12 is provided with a worm screw 121 and transmission one train of reduction gears 13, this train of reduction gears 13 comprises and worm screw 121 ingear driving wheel 131 and the coaxial power wheels 132 that are provided with a less number of teeth, this power wheel 132 and flower wheel 133 engagements, and the also coaxial less output wheel of a number of teeth 134 that is provided with of flower wheel 133, to reach the purpose of deceleration.Output wheel 134 is engaged with a tooth bar 14, and an end of this tooth bar 14 passes housing 11 and stretches to windshield 3; The two ends appropriate position of tooth bar 14 in housing 11 is respectively equipped with two salient points 141,142, and upper and lower both sides are respectively equipped with the limit switch 151,152 of working in coordination with two salient points in the housing 11, with the moving range of restriction tooth bar 14; The end that tooth bar 14 stretches to Windshield 3 is provided with the plus-minus screw 143 that can adjust collapsing length and utilizes nut 144 to fix its position, and the front end of plus-minus screw 143 is provided with a rubber sheath 145, to avoid directly bump Windshield 3 of plus-minus screw 143.

When automobile is in dead ship condition, tooth simple and unadorned 14 stretches out downwards and makes rain brush 2 leave Windshield 3 surfaces, when automobile starting, motor 12 is subjected to relay 13 control and rotates and through reducing gear 13 tooth bar 14 is withdrawn in housing 11, when last salient point 142 touches limit switch 152, promptly transmit signal to relay 13 stall to cut off motor 12 power supplys, rain brush 2 promptly attaches on the Windshield 3 and carries out work; Otherwise, after automobile kills engine, relay 13 will be controlled motor 12 counter-rotatings and through train of reduction gears 13 tooth bar 14 be stretched out downwards, make rain brush 2 break away from Windshield 3 surfaces gradually, when 14 times salient points 141 of tooth bar touch limit switch 151, promptly transmit signal to relay 13 stall, make rain brush 2 return to the state that breaks away from Windshield 3 surfaces to cut off motor 12 power supplys.

Rain brush 2 can be adjusted as required with the distance of Windshield 3, loosen nut 144 and rotate plus-minus screw 143 at first during adjustment, and when screw 143 to be adjusted stretched out suitable length, block nut 144 again.

Compare with existing windshield wiper protector, of the present utility model simple in structure, control conveniently its action Also more accurate. When parking of automobile, can guarantee that rain brush breaks away from windscreen surface, thereby reduce contact Time, prolong its service life.
