Detailed Description
The invention is further illustrated by the figures and examples.
A method for realizing the function of alternating different stop positions of a wiper blade of an automobile comprises the steps of controlling different stop positions of a wiper motor to realize different lodging states of an adhesive tape when the wiper motor stops, and realizing the back-and-forth swinging wiping action of the wiper through a wiper four-link mechanism when the wiper motor is a single-rotation wiper motor, wherein as shown in figure 4, when the initial position of the wiper is that a wiper connecting rod 404 and a crank 403 are parallel, the wiper is at a lower limit position, the wiper rotates clockwise, the wiper is in an upward wiping process in the process of 0-180 degrees, the adhesive tape lodging is a state A in figure 1, the wiper is in a downward wiping process in the process of 180-360 degrees, and the adhesive tape lodging is a state B in figure 1; when the wiper is switched from a running state to a stopping state and stops at the position I, the wiper blade 2 is in the process of running and stopping from top to bottom, and the rubber strip is in a lodging state B; when the wiper is switched from the running state to the stopping state and stops at the position II, the wiper blade 2 is in the process of running from bottom to top, and the rubber strip is in the lodging state A at the moment; the wiper motor 402 is controlled to select different parking positions according to a certain rule when parking each time, and the parking positions are respectively stopped at a 0-degree parking position I and an alpha-degree parking position II to realize the alternation of the adhesive tape lodging states in different parking periods.
When the wiper motor is a positive and negative rotation wiper motor, the wiper motor does not rotate in a 360-degree single direction when in work, but the output shaft of the motor swings back and forth between beta 1 degrees and beta 2 degrees shown in figure 5 in a certain area, and then the wiper arm is driven to swing back and forth through a link mechanism or directly to realize the wiping action of the wiper; when the wiper is stopped, different parking positions can be selected. When the current period of the wiper is at a stopping position I, the wiper motor directly returns to the stopping position I anticlockwise; when the current period of the wiper is the stopping position II, the wiper motor moves to the position 1 anticlockwise firstly, and then moves to the position II from the position I clockwise; when the wiper directly returns to the position I, the movement direction of the wiper blade is from top to bottom, and the falling state of the wiper blade is a state B shown in figure 1 due to the action of friction force between the wiper blade and the glass; when the wiper motor returns to the position I first and moves to the position II from the position I, the movement direction of the wiper blade 2 is from bottom to top, the lodging state of the rubber strip of the wiper blade is the state A shown in figure 1 at the moment, two different parking modes are respectively selected according to a certain alternation rule to realize the alternation of the lodging states of two different rubber strips, and therefore the purpose of prolonging the service life of the rubber strip is achieved.
The angles alpha, beta 1 and beta 2 can be calibrated according to actual conditions.
The above-mentioned certain alternation rule can be, but not limited to, such as the power-on and power-off cycle of the vehicle body, the parking times of the wiper, the wiping times of the wiper, the service time cycle of the wiper (such as one month and ten days), etc.
The power-on and power-off cycle refers to a complete driving process, and includes but is not limited to power-on of a vehicle body K15, power-off of a vehicle body K15 when the vehicle speed is greater than a certain value (which can be calibrated to be 5 KM/h); some steps may be taken, for example, only the power-on and power-off of the vehicle body is judged, or only the vehicle speed is judged to be larger than a certain value.
The wiper stop frequency is a counting period from the wiper running to the completion of the wiper stop, and a complete action period is recorded as 1 stop; the wiper stop times can be set to 10 times (but not limited to 10 times, and the times can be calibrated) to alternate one stop state.
The number of wiping times of the wiper is counted by taking a complete wiping process of the wiper (ascending to the upper reversal point and then returning to the lower reversal point) as a counting period. The number of times may be set to 100 times (but not limited to 100 times, which may be calibrated) to alternate the parking state.
The alternate period of the power-on and power-off period, the parking times of the windscreen wiper and the wiping times of the windscreen wiper can be counted by the windscreen wiper, and also can be counted by the vehicle body controller, a parking state signal is sent to the windscreen wiper through LIN communication, and the windscreen wiper receives and executes the state instruction.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
