When degree reduces, the resistance value of Rx becomes larger.K1 is normally closed switch, and when firing key is extracted, K1 is kept closed；Firing key is inserted
When upper, K1 is remained off；K2 is high-order limit switch, and when windscreen wiper Rocker arm 4 is jacked to extreme higher position, K2 is disconnected, and is cut
The power supply of disconnected reversing dc motor M, the motor stall；When windscreen wiper Rocker arm 4 is not jacked to extreme higher position or
When person is not jacked up, K2 is closed；K3 is switched for open type, and when firing key is extracted, K3 is remained off；Firing key
When plugging, K3 is kept closed；K4 is low level limit switch, and when windscreen wiper Rocker arm 4 is not jacked up, K4 remains open shape
State；When windscreen wiper Rocker arm 4 is jacked up, K4 is kept closed；K5 is emergency button, i.e., in emergency situations, occupant can on vehicle
To control this control device manually.
When firing key is pulled up, K1 is kept closed, and K3 is remained off, and is divided into following three kinds of situations：
The first situation：Prevent rain shaving blade 3 from being freezed together with windshield 1.It keeps out the wind when temperature sensor Rx is measured
When the surface temperature of glass 1 is less than 0 DEG C, the resistance value of Rx becomes larger, circuit 1：Power supply B → emergency button K5 (closure) → K1 (closure)
The cathode of → high position limit switch K2 (closure) → R1 → Rx → bonding → power supply B；As temperature sensor Rx, to measure temperature low
When 0 DEG C, the resistance value of Rx becomes larger, then the partial pressure on Rx also becomes larger, operating voltage of the partial pressure more than voltage-stablizer VS1 on Rx, VS1
Conducting, then the base stage of VT1 and emitter form positively biased and are connected, circuit 2：Power supply B → emergency button K5 (closure) → K1 (is closed
Close) cathode of → high position limit switch K2 (closure) → VT1 → relay J1 coils → bonding → power supply B, J1 coils obtain it is electric,
Normally opened contact is closed, circuit 3：Power supply B → emergency button K5 (closure) → K1 (closure) → high position limit switch K2 (closure) →
The cathode of relay J1 contacts (closure) → dc motor M → power supply B, dc motor M obtain power supply and rotate (such as Fig. 5
It is shown), motor reel 9 drives turntable 10 to rotate, and turntable 10 drives drive rod 11 to rotate, and drive rod 11 jacks up windscreen wiper Rocker arm 4,
Rain shaving blade 3 is detached with windshield 1 at this time.Specific power transfer route：Reversing dc motor M, which is powered, rotates (forward direction) → electricity
Motivation axis 9, which rotates (forward direction) → turntable 10 and rotates (forward direction) → drive rod 11, rotates (rise) → windscreen wiper Rocker arm 4 by jack-up → rain
Scraping blade 3 is detached with windshield 1.
The second situation：Prevent rain shaving blade 3 from being scorched.When the surface temperature of temperature sensor measurement to windshield 1 is high
When maximum temperature (such as can be set as 60 DEG C), the resistance value of Rx becomes smaller, circuit 1：Power supply B → emergency button K5 (closure) → K1
The cathode of (closure) → high position limit switch K2 (closure) → R1 → Rx → bonding → power supply B, due to the partial pressure of Rx also become smaller it is (small
In VS1 conducting voltages), VS1 is not turned on, VT1 cut-offs.Circuit 2：Power supply B → emergency button K5 (closure) → K1 (closure) → height
The cathode of position limit switch K2 (closure) → Rx → R2 → bonding → power supply B, when the partial pressure of Rx becomes small, then the partial pressure on R2 will
Become larger.The temperature that temperature sensor Rx is measured at this time is more than maximum temperature, and Rx resistance values become smaller, and partial pressure also becomes smaller, then on R2
Partial pressure becomes larger, and the partial pressure on R2 is more than VS2 operating voltages, VS2 conductings at this time, and the base stage and emitter of VT2 form positively biased and lead
It is logical, circuit 3：Power supply B → emergency button K5 (closure) → K1 (closure) → high position limit switch K2 (closure) → VT2 → relay
The cathode of J2 coils → bonding → power supply B, J2 coils obtain electric, normally opened contact closure, circuit 4：Power supply B → emergency button K5
(closure) → K1 (closure) → high position limit switch K2 (closure) → relay J2 contacts (closure) → dc motor M → power supply
The cathode of B, dc motor M obtain power supply and rotate (as shown in Figure 5), and motor reel 9 drives turntable 10 to rotate, 10 band of turntable
Dynamic drive rod 11 rotates, and drive rod 11 jacks up windscreen wiper Rocker arm 4, and rain shaving blade 3 is detached with windshield 1 at this time.Specific power passes
Pass route：Reversing dc motor M be powered rotation (forward direction) → motor reel 9 rotate (forward direction) → turntable 10 rotate (forward direction) →
Drive rod 11 rotates (rise) → windscreen wiper Rocker arm 4 and is detached by jack-up → rain shaving blade 3 with windshield 1.
The third situation：When the surface temperature of windshield 1 that temperature sensor measures is more than 0 DEG C, and less than the highest temperature
When spending (60 DEG C), the partial pressure of Rx is less than VS1 operating voltages, and the partial pressure of R2 is less than VS2 operating voltages, and VS1 and VS2 end, then
VT1 and VT2 also ends, and dc motor M is not rotated, the present apparatus does not work, i.e., does not rise because without electric current.
VD1 is instantaneous voltage when eliminating relay J1 coil blackouts, and circuit is：Relay J1 coils → VD1 → relay
Device J1 coils.
VD2 is instantaneous voltage when eliminating relay J2 coil blackouts, and circuit is：Relay J2 coils → VD2 → relay
Device J2 coils.
When firing key is plugged, K1 is remained off, and K3 is kept closed, and is divided into following two situations：
The first situation：Before firing key is plugged, windscreen wiper Rocker arm 4 is jacked up, then K4 is closed, circuit：Power supply B → K3
The cathode of (closure) → low level limit switch K4 (closure) → emergency button K5 (closure) → dc motor M → power supply B, it is electronic
Machine M antiports, as shown in fig. 6, windscreen wiper Rocker arm 4 is fallen, specific power transfer route：Reversing dc motor M, which is powered, to be rotated
(reversed) → motor reel 9, which rotates (reversed) → turntable 10 and rotates (reversed) → drive rod 11, rotates and (falls) → windscreen wiper Rocker arm 4
Fall → rain shaving blade 3 contacts with windshield 1, it is ensured that Wiping device normal use.
The second situation：Before firing key is plugged, windscreen wiper Rocker arm 4 is not jacked up, then K4 disconnect, motor M because
To lose power supply B without rotating.
Based on above-mentioned, the device, in 1 surface set temperature sensor Rx of vehicle windscreen, with temperature sensor Rx come
The temperature on 1 surface of vehicle windscreen is measured, two motor assemblies are set in the lower section of windshield 1, each motor has
The windscreen wiper Rocker arm 4 of one drive rod 11 and windscreen wiper assembly 2 contacts with each other, in the case where firing key is pulled up, if keeping out the wind glass
When 1 surface temperature of glass is less than 0 DEG C (temperature of water freezing) or higher than highest setting temperature (such as 60 DEG C), control device is to straight
Galvanic electricity motivation M is powered, and by the rotation of dc motor M, turntable 10 and drive rod 11 is driven to rotate, and then vehicle windscreen wiper is shaken
Arm 4 rises, and rain shaving blade 3 will not be contacted with windshield 1 at this time, avoids rain shaving blade 3 and freezes with windshield 1 or kept off
Wind glass 1 scorches, it is ensured that 3 normal use of rain shaving blade simultaneously prolongs the service life；When firing key is inserted into, rain shaving blade 3 always with
Windshield 1 contacts, it is ensured that normal use windscreen wiper.
As known by the technical knowledge, the utility model can pass through other essence without departing from its spirit or the reality of essential feature
Scheme is applied to realize.Therefore, embodiment disclosed above, all things considered are all merely illustrative, and are not only
