In some optional embodiments, the vehicle further comprises: a rainfall sensor 210 and a controller, wherein the rainfall sensor 210 is used for detecting rainfall information; the controller is connected with the wiper blade assembly 100 and electrically connected with the rainfall sensor 210; for controlling the swing of the wiper arm 120 according to the rainfall information.
When the rainfall sensor 210 transmits the detected rainfall information to the controller, and when the rainfall represented by the rainfall information reaches a preset value, the controller controls the wiper arm 120 to swing, so that the function of automatically opening the wiper assembly 100 is realized.
In a specific example, the rain sensor 210 is installed at an upper portion of the windshield 200, and the sliding guide is installed at a front of the main driving side front windshield 200 outside the vehicle, and a length of the guide is determined by considering a size of the front windshield 200 and a length of the wiper blade 130. The wiper arm 120 is connected to the sliding rail at one end and to the wiper blade 130 assembly at the other end. The integrated single wiper blade 130 assembly includes a water spray device that controls the direction of the cleaning solution spray. When the wiper does not operate, the wiper blade 130 is positioned outside the front passenger side windshield 200 and is in a horizontal state as shown in fig. 1.
Fig. 2 shows a schematic diagram of the operation of a wiper blade (also called a wiper assembly). The wiper arm 120 drives the wiper blade 130 to move clockwise (i → ii) around the point a, when the wiper blade 130 moves to the vertical position (i.e. the position B), the wiper arm 120 starts to translate from the point a to the point B along the sliding rail (the third stage in the figure), and then the wiper blade 130 returns to the initial horizontal position (i → v → q) along the path, and the wiper blade 130 finishes the wiping operation in the process. The wiper is set to two modes during working, namely a rain mode and a foreign matter removing mode.
Mode one (rain mode): when the rainfall sensor 210 detects rain, the wiper function is automatically turned on. The movement locus of the wiper blade 130 for one period is (i) → ((c)), as shown in fig. 3.
Mode two (foreign substance removal mode): the mode is divided into A, B two gears.
Specifically, when foreign matters are on the front windshield 200 right in front of the copilot position and need to be cleaned, the A gear is turned on, the wiper starts to work and moves from the initial horizontal position to the middle vertical position, when the wiper blade 130 moves to the middle vertical position for the first time, the water spraying function of the water spraying device integrated on the wiper blade 130 is automatically turned on, the water spraying direction is the copilot direction (namely the arrow direction corresponding to the wiper blade at the c position), the moving track of the wiper blade 130 is (i) (/), and the reciprocating working frequency of the wiper can be automatically set and determined according to the situation. After the foreign matters such as dust and the like in the area on the front windshield 200 are removed, the wiper blade 130 works again from the horizontal position according to the trajectory → → and finally returns to the original horizontal position, thereby preventing the water mark from appearing in the middle position on the front windshield 200 to influence the sight of the driver.
When foreign matters are required to be cleaned on the front windshield 200 right in front of the main driving position, the B gear is started, the wiper starts to work, the wiper moves to the middle vertical position from the initial horizontal position through the first step, when the wiper blade 130 moves to the middle vertical position for the first time, the water spraying function can be automatically started by the water spraying device integrated on the wiper blade 130, the water spraying direction is the main driving direction (namely the arrow direction corresponding to the wiper blade at the c position), the moving track of the wiper is secondly → thirdly → ② → thirdly → ③, and the reciprocating working times of the wiper can be automatically set and determined according to the situation. After the foreign matter such as dust is removed from the area, the wiper blade 130 returns to the original horizontal position through the fourth stage.
The second mode area has stronger pertinence, saves time and oil consumption, is cleaner to wipe, saves the amount of washing liquid and can improve the visibility during driving.
To sum up, the utility model provides a wiper assembly 100 of single wiper blade formula realizes the brush work of scraping of single wiper blade 130 with the help of this device of slide rail 110. The use of the single wiper blade assembly 100 advantageously avoids the occurrence of watermarks in the intermediate position that could affect the driver's sight when the wiper blade 130 is rewrapped. In addition, when the foreign matters on the windshield 200 need to be cleaned in the driving process, the wiper is only used for wiping a certain area, so that the wiper is cleaner, the working time of the cleaning solution and the wiper is saved, the visibility during driving is improved, and the safety on a driving road is guaranteed to a certain extent.
