It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention in a schematic way, and the drawings only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, and the form, amount and proportion of each component may be changed arbitrarily in actual implementation, and the layout of the components may be more complicated.

Example 1

Referring to fig. 2-4, a windshield washer device with adaptive length is shown, which includes a washer 100, an angle sensor, and a controller, where the washer 100 includes a main brush 110, an auxiliary brush 120, a connecting rod 130, and a driving device, the driving device includes a first motor 121 and a second motor, one end of the connecting rod 130 is rotatably connected to a vehicle body, the second motor is disposed on the connecting rod to make the connecting rod rotate relative to the vehicle body, the other end of the connecting rod 130 is detachably connected to the main brush 110, the auxiliary brush 120 is radially disposed on the main brush 110, both the main brush 110 and the auxiliary brush 120 are in contact with a windshield, the end of the auxiliary brush 120 is provided with the first motor 121, the output end of the motor is connected to a pulley, the main brush 110 is provided with a guide rail 111 at a position corresponding to the auxiliary brush 120, the vehicle body is provided with the angle sensor, the angle sensor can measure a rotation angle a of the connecting rod 130 of the washer 100, the controller is connected to the washer 100 and the angle sensor, and the controller can control the auxiliary brush to radially expand or contract in the main brush according to the rotation angle a rotation angle of the measured by the rotation angle of the connecting rod, so as to control a distance of the wiper of the rotation angle of the motor on the connecting rod, and further to change the length of the washer 120, thereby realizing the cleaning area of the windshield washer.

It should be noted that the use of the angle sensor has a specific meaning, which can improve the cleaning efficiency of the cleaning device and reduce the probability of failure.

In the prior art, when the distance measuring sensor is used for controlling the radial movement distance of the auxiliary brush in the main brush, the length of the auxiliary brush is adjusted by directly measuring the radial distance between the end point of the main brush and the gear edge, the length change corresponding to the next process cannot be judged, and the condition of delaying judgment is easily caused. For example, referring to fig. 1, in a single movement, when the distance between the end point of the main brush and the edge of the step is L1, it cannot be determined whether the end point of the main brush is at the deflection angle A1 or A2, it cannot send an instruction to the auxiliary brush in advance, and it is only possible to perform adjustment after receiving the data of the distance measuring sensor, so that the adjustment of the length of the auxiliary brush and the movement process of the washer are not synchronized, and there is a lag, resulting in poor cleaning effect.

And in the embodiment of the utility model, when the radial motion distance of main brush, the deflection angle in the purger motion process is all different through utilizing the vice brush of deflection angle control, can obtain the vice brush length under the next state very easily according to current deflection angle, has solved the adjustment of the vice brush length that exists among the prior art and the motion process of purger can not be synchronous, have hysteretic problem.
