The utility model also provides a vehicle. According to the utility model discloses a vehicle includes according to the utility model discloses the wiper 1 of above-mentioned embodiment, according to the utility model discloses a vehicle has advantages such as the driver field of vision is good, the driving safety is high.
In some embodiments, the vehicle has a windshield 2 and the wiper 1 has a starting position where the wiper 1 is located on a bottom side of the windshield 2 and a starting position where the auxiliary wiper arm 13 is disposed near the bottom side of the windshield 2. In other words, the wiper 1 located at the home position is located on the bottom side of the windshield 2, and the attachment arm 13 of the wiper 1 located at the home position is disposed on the side close to the bottom of the windshield 2.
Note that, as shown in fig. 1, the bottom of the windshield 2 is below the windshield 2. In the starting position, the auxiliary wiper arm 13 is arranged on the side close to the bottom of the windscreen 2, i.e. the auxiliary wiper arm 13 is located below the main wiper arm 12. Thus, because the bottom edge of windshield 2 is generally curved, wiper 1 on the left and/or right side of windshield 2 can be hidden beneath the left and/or right side of the curved bottom edge of windshield 2 when not in use. At the same time, the main wiper arm 12 located above the sub wiper arm 13 can wipe more of the area located above the bottom edge of the windshield 2 and give the driver more visibility.
In some embodiments, wiper 1 includes left and right wipers for wiping windshield 2, which are disposed at intervals in the width direction of the vehicle. This allows more area of the windscreen 2 to be wiped by the two wipers, which in turn allows the driver or passenger to have a good view.
In some embodiments, the main wiper arm 12 of the left wiper and the main wiper arm 12 of the right wiper are driven by a first wiper motor, and the subsidiary wiper arm 13 of the left wiper and the subsidiary wiper arm 13 of the right wiper are driven by a second wiper motor. Thus, the main wiper arm 12 of the left wiper and the main wiper arm 12 of the right wiper can be driven by the first wiper motor of high power, and the subsidiary wiper arm 13 of the left wiper and the subsidiary wiper arm 13 of the right wiper are driven by the second wiper motor of low power.
It is understood that the main arm 12 of the left wiper, the auxiliary arm 13 of the left wiper, the main arm 12 of the right wiper, and the auxiliary arm 13 of the right wiper may be driven by a single wiper motor, for example, the main arm 12 of the left wiper and the auxiliary arm 13 of the left wiper are fixedly connected to one end of the arm base 11 close to the left wiper, the main arm 12 of the right wiper and the auxiliary arm 13 of the right wiper are fixedly connected to one end of the arm base 11 close to the right wiper, the main arm 12 of the left wiper or the auxiliary arm 13 of the left wiper is provided with a first synchronous pulley, the main arm 12 of the right wiper or the auxiliary arm 13 of the right wiper is provided with a second synchronous pulley, and a synchronous belt is connected between the first synchronous pulley and the second synchronous pulley, and when the wiper motor drives the first synchronous pulley or the second synchronous pulley, the synchronous belt drives the main arm 12 of the left wiper, the right arm 12 of the left wiper, the main arm 12 of the right wiper, and the auxiliary arm 13 of the right wiper to rotate synchronously.
In some embodiments, the lower edge of the windshield 2 is provided with a belt-shaped shielding layer 21 extending along the length of the lower edge of the windshield 2, the shielding layer 21 is used for shielding a view from the outside of the vehicle, and the rotation area of the main arm head 121 of the main arm 12 and/or the sub arm head of the auxiliary arm 13 on the windshield 2 is positioned in the shielding layer 21. Thus, when wiper 1 swings, a wiping blind area caused by rotation of main arm head 121 and/or sub arm head does not occur on windshield 2.
