DETAILED DESCRIPTION

[0023] The embodiments of the utility model will be further described in detail below in combination with the drawings and examples.

[0024] Example 1:

[0025] As shown in the accompanying Figure 1 to the accompanying Figure 5 As shown:

[0026] The utility model provides a kind of automobile wiper control device, including controller 1, the top of controller 1 is rotatably provided with pipe shaft 2 with airtight bearing, and the top of pipe shaft 2 is fixedly provided with swing rod 3;Swing rod 3 is slidably provided with sliding rod sleeve 4 outside;Swing rod 3 is fixedly provided with air telescopic rod 301 inside, and the telescopic end of air telescopic rod 301 is fixedly connected with sliding rod sleeve 4;Articulated rod 5 is hingedly arranged outside sliding rod sleeve 4, and wiper group 6 is hingedly arranged at the other end of articulated rod 5;Spring telescopic rod 7 is also hingedly arranged between articulated rod 5 and sliding rod sleeve 4;The top of controller 1 is slidably provided with sliding rack rod 8;Drive motor 9 is fixedly arranged outside controller 1;Four-way pipe 11 is fixedly arranged inside controller 1, and the top of four-way pipe 11 is communicated below pipe shaft 2.

[0027] Among them, the outside of pipe shaft 2 is fixedly provided with driven gear 201;Sliding rack rod 8 is engaged with driven gear 201.

[0028] Among them, the both ends of sliding rack rod 8 are fixedly provided with strip frame 801 and connecting plate 802 respectively.

[0029] Among them, the shaft end of drive motor 9 is fixedly provided with transmission wheel 901, and the top of transmission wheel 901 is fixedly provided with eccentric rod 902, and eccentric rod 902 is slidably arranged in strip frame 801.

[0030] Among them, the side of controller 1 is fixedly provided with control piston 10, and the telescopic end of control piston 10 is fixedly connected with connecting plate 802, and the movement of sliding rack rod 8 controls the telescopic of control piston 10;Control piston 10 is communicated with four-way pipe 11.

[0031] Among them, a solenoid valve A12 is connected above the four-way pipe 11; two sets of solenoid valves B13 are connected below the four-way pipe 11, and a three-way valve is connected to each of the solenoid valves B13. A one-way valve A14 is connected above the three-way valves, and a set of one-way valves B15 is connected below the two three-way valves.

[0032] like Figures 1-5 As shown, starting the drive motor 9 drives the transmission wheel 901 and the eccentric rod 902 to rotate. The eccentric rod 902 drives the sliding rack rod 8 to move. The sliding rack rod 8 drives the driven gear 201 to rotate, which in turn drives the tube shaft 2 to rotate, causing the swing arm 3 to swing. At the same time, the sliding rod sleeve 4, the hinge rod 5, and the wiper assembly 6 swing to wipe the rain. The spring telescopic rod 7 can bring the wiper assembly 6 close to the windshield.

[0033] While wiping the rain, the connecting plate 802 drives the control piston 10 to move. When the control piston 10 extends, it draws out the air in the air telescopic rod 301 and retracts the air telescopic rod 301. The retraction of the air telescopic rod 301 will pull the sliding rod sleeve 4 to retract, thereby reducing the movement range of the wiper assembly 6.

[0034] Conversely, controlling the piston 10 to contract can increase the range of movement, thereby reducing the blind spots of the wipers and expanding the wiper range;

[0035] Since the wiper positions vary between different car models, the control sequence can be adjusted according to the specific car model, and appropriate sizes can be selected during manufacturing to achieve wide-area wiping.

[0036] Example 2:

[0037] Based on Example 1, by controlling the system or a button, a set of solenoid valves B13 is opened and solenoid valve A12 is closed. At this time, when the control piston 10 contracts, air will pass through the opened solenoid valve B13 and the one-way valve A14 connected to it to be discharged. When the control piston 10 extends, air is input through the one-way valve B15. At this time, the wipers do not extend.

[0038] Two sets of one-way valves A14 can be used to supply air to different parts. For example, by connecting one set of one-way valves A14 to the windshield washer fluid tank, windshield washer fluid can be sprayed by pressurizing.

[0039] Another set of one-way valves A14 is connected to the external circulation to increase the ventilation efficiency. By controlling the opening and closing of the two sets of solenoid valves B13, different functions can be selected.

[0040] The specific usage and function of this embodiment are as follows:

[0041] The utility model discloses, using, open electromagnetic valve A12 closes two groups of electromagnetic valve B13, start drive motor 9 drive transmission wheel 901 and eccentric rod 902 rotation, eccentric rod 902 drive sliding rack bar 8 removes, utilize sliding rack bar 8 drive driven gear 201 rotation, and further drive pipe axle 2 rotation, swing link 3 is swung, simultaneously, sliding rod cover 4, hinged link 5 and windshield wiper group 6 swing and scrape rain, spring telescopic link 7 can be close windshield wiper group 6 to windscreen, and the windshield wiper group 6 is scraped rain;

[0042] Scrape rain simultaneously, connecting plate 802 drive control piston 10 removes, extract the air in air telescopic link 301 when control piston 10 stretches, and air telescopic link 301 contracts, and air telescopic link 301 contracts can pull sliding rod cover 4 and contract, and further reduce the moving amplitude of rain brush group 6, and conversely can increase the moving amplitude, and further reduce the dead angle of scraping rain, and expand the scraping rain range, because the position of windshield wiper of different vehicle models is also different, according to different vehicle models, can adjust control order as needed, and select corresponding size when making, to realize wide range scraping rain;

[0043] One-way valve A14 can be connected to the input structure as needed;

[0044] Can choose not to stretch when the windshield wiper works, or the cycle mode of stretching once and not stretching once to work;

[0045] Through control system or button, open a group of electromagnetic valve B13, close electromagnetic valve A12, when control piston 10 contracts, air passes through the opened electromagnetic valve B13 and its connected one-way valve A14 and is discharged, control piston 10 stretches through one-way valve B15 and inputs air, when the wiper does not stretch, utilize two groups of one-way valve A14 can supply air for different parts, realize the selection of different functions.
