Example 2

Embodiment 2 of the present invention provides a vehicle, including at least two wipers 100 provided in embodiment 1, please refer to fig. 3, which is specifically described as follows:

Fig. 3 is a schematic view illustrating the wiper 100 mounted on the front windshield 17 of the vehicle, the front windshield 17 of the vehicle is edge-sealed, and a first magnetic member 172 is disposed at the glass edge-sealing position, and a second magnetic member 158 is disposed at the first sensor 153 and the second sensor 155 of the wiper 100, in this embodiment, the first sensor 153 and the second sensor 155 are both mechanical sensors, so as to measure the distance between the wiper 100 and the edge of the front windshield 17 corresponding thereto.

The sensor detects a pressure value and feeds back the pressure value to the controller, the controller controls the relative position of the first scraping blade 12 and the second scraping blade 13 of the wiper 100 and the wiping length to be adjusted, and the distance between the wiper 100 and the edge of the front windshield 17 is basically a certain value through the simultaneous action of the first scraping blade 12 and the second scraping blade 13, so that the area of the wiper 100 wiping the front windshield 17 in the wiping process is changed.

The two wipers 100 are mounted on the front windshield 17 of the vehicle body, which are respectively a main wiper and an auxiliary wiper, both of which are mounted on the vehicle body, and the wiper blade corresponds to the front windshield 17.

Fig. 4 is a control block diagram of the wiper 100, and fig. 5 is a control logic block diagram of the air pump, as shown in fig. 4 and 5.

The combination switch is closed, the controller is electrically connected with the sensor and the driving assembly 14 respectively, that is, the controller is electrified with the first sensor 153, the second sensor 155, the motor and the air pump, in this embodiment, the first sensor 153 and the second sensor 155 are both capacitive sensors, the first magnetic member 172 at the edge of the front windshield 17 is N-pole, and the second magnetic member 158 arranged on the first sensor 153 and the second sensor 155 is N-pole, so that the first magnetic member 172 and the second magnetic member 158 generate repulsive force. When the sensor is closer to the edge of the glass, the repulsive force is larger, the numerical value of the force detected by the sensor is compared with a preset calibration value, the controller judges according to the comparison condition and the environmental factor, the air pump is controlled by the motor to inflate or deflate the air cylinder in the driving assembly 14, so that the size of the scraping and brushing area of the scraping and brushing blade is controlled, and the fault condition and the mode are fed back to the combination instrument through the CAN, so that an operator is fed back.

specifically, the controller determines the time step length for receiving the sensor according to the frequency of the movement of the wiper 100, compares the signal value fed back by the sensor with a calibrated value (note: equivalent to safe distance conversion), when the measured value is equal to the calibrated value, the air pump does not work, and the wiper 100 keeps the state to continue wiping movement; when the measured value is smaller than the calibration value, the air pump increases the air pressure of the air cylinder to make the first wiper blade 12 and the second wiper blade 13 move away from each other, so that the wiping area of the wiper 100 is increased; when the measured value is greater than the calibration value, the air pump reduces the air pressure of the air cylinder, so that the first scraping blade 12 and the second scraping blade 13 move close to each other, the staggered length of the scraping blades is increased, the effective scraping area is reduced, and the scraping blades and the edge of the front windshield 17 cannot interfere in the moving process.

Considering that the stroke of the cylinder is limited, if the pressure value of the cylinder is the minimum and the detection value fed back by the sensor is greater than a calibrated value, a fault is displayed, and the mounting point of the scraping arm of the wiper 100 needs to be adjusted. It is understood that the calibration value does not necessarily refer to a specific numerical value, and may be a previously preset numerical value range, and the detection value is compared with the preset numerical value range.

The vehicle that this embodiment provided has above-mentioned windscreen wiper 100's advantage, with the sensor, the variable doctor-bar combines, and combine intelligent recognition and control action through the controller, can increase the brush area of scraping of windscreen wiper 100 according to actual conditions, be favorable to the region in clean preceding windscreen 17 upper right corner, can realize cleaing away the spot area on the preceding windscreen 17 and reach more than 95%, and through the distance between discernment doctor-bar and preceding windscreen 17 edges, guarantee windscreen wiper 100 in the motion process, can not take place to interfere with the automobile body, and then promote whole car quality, strengthen user's experience.

it should be noted that, in the case of conflict, the features in the embodiments of the present invention may be combined with each other.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
