The automobile windscreen wiper is often used in rainy and snowy weather and is used for removing rain, snow and dust on a windshield to ensure that a driver still has good sight when driving an automobile in bad weather. Since the driver needs to see clearly the scenery or road condition in front of the vehicle through the glass area of the wiper, the vehicle body must be designed to have a large enough wiping area. In the driving process of the vehicle, the larger the wiping area is, the wider the visual field of a driver is, and the higher the driving safety of the vehicle is.
The conventional wiper blade 10 generally has one or more wiper rods 11, for example, as shown in fig. 1, the number of the wiper rods 11 is two, a wiper blade is disposed on the wiper rod 11, a swing arm 113 is connected to the wiper rod 11, and a driving mechanism drives the wiper rod 11 to swing left and right by driving the swing arm 113, so as to implement a wiping motion of the automobile wiper blade. Since the length of the wiper rod 11 is fixed, the area of the wiper blade formed is fixed and limited, and is usually a sector or a sector with a plurality of overlapping sectors, and fig. 1 shows the wiping area of a conventional wiper blade 10, which is the sum of the areas of the two sectors. Because the length of the windshield wiper rod 11 is fixed, the area of the windshield wiper blade for wiping is limited, so that the visual field range of an automobile driver is limited, and a certain visual blind area exists in the front window area of the driver, which is not beneficial to the safety of automobile driving.
In view of the above problems, the present invention provides a wiper blade and a vehicle, including: at least one wiper lever, at least one drive mechanism, and at least one cam mechanism; each wiper rod includes: the wiper comprises a main wiper rod and an auxiliary wiper rod, wherein the auxiliary wiper rod is arranged in the main wiper rod; each cam mechanism comprises a cam and a cam shaft, and the cam is fixed on the cam shaft; the driving mechanism is connected with the head end of the main wiper rod and sleeved on the cam shaft, one end of the auxiliary wiper rod is abutted against the cam, and the other end of the auxiliary wiper rod extends out of the tail end of the main wiper rod under the driving of the cam when the main wiper rod swings. Like this the brush can be scraped to other regions on the windshield to the one end that vice wiper stem stretches out from main wiper stem to increased the brush area of scraping of wiper stem, makeed the motorist field of vision scope wider. The windscreen wiper and the vehicle provided by the utility model are used for solving the problems that the wiping area of the automobile windscreen wiper is small, the visual field range of an automobile driver is greatly limited and the safe driving of the automobile is not facilitated due to the fixed length of the traditional windscreen wiper.
The wiper blade and the vehicle provided by the embodiment of the utility model are further explained below.
The present embodiment provides a wiper blade. Fig. 2 is a sectional view of a wiper blade according to an embodiment of the present invention, fig. 3 is a partial sectional view of the wiper blade according to the embodiment of the present invention, and fig. 4 is a schematic view of a wiping area of the wiper blade according to the embodiment of the present invention.

Referring to fig. 4, when the motor 131 moves to move the main wiper rod 111 upward, the sub wiper rod 112 moves synchronously with the swing of the main wiper rod 111, and since one end of the spring 114 is connected to the main wiper rod 111, the sub wiper rod 112 rolls upward along the edge of the cam 121 under the pulling of the spring 114, and the sub wiper rod 112 is slowly pushed up by the cam 121, and the side of the sub wiper rod 112 close to the cam 121 is gradually pushed out of the swing arm 113 to protrude outside the main wiper rod 111.
Specifically, referring to fig. 4, a curve a is a movement track of the front end of the auxiliary wiper rod, a curve B is a movement track of the front end of the main wiper rod, a shadow area between the curve a and the curve B is a wiping area when the one end of the auxiliary wiper rod 112 extends outward to wipe the windshield, and a blank sector area is a wiping area of the main wiper rod 111, so that, compared with a wiper only provided with the main wiper rod 111, in the embodiment of the present application, rainwater, impurities and the like on the windshield are wiped off by wiper blades arranged on the auxiliary wiper rod 112 and the main wiper rod 111, so that a larger wiping area is formed, and the purpose of increasing the field of view of the driver is achieved.
Until the main wiper rod 111 moves right above the cam 121, the radius of the cam 121 reaches the maximum, the distance for ejecting the sub wiper rod 112 also reaches the maximum, the sub wiper rod 112 moves synchronously under the swing of the main wiper rod 111, one side of the sub wiper rod 112 close to the cam 121 is ejected out of the swing arm 113, the sub wiper rod 112 is ejected up by the cam 121 together with the limit structure 1121 provided thereon, and the spring 114 is compressed to the minimum here.
When the motor 131 drives the main wiper rod 111 to move continuously, the auxiliary wiper rod 112 is driven by the main wiper rod 111 to retract into the swing arm 113 along the edge of the cam 121, where it should be noted that the swing arm 132 is fixedly connected to the main wiper rod 111, so the swing arm 132 drives the main wiper rod 111 to form a wiping angle of 110-120 °, when the motor 131 drives the main wiper rod 111 to swing to 120 °, one wiping operation is completed, and the main wiper rod 111 drives the auxiliary wiper rod 112 to move repeatedly along with the periodic movement of the motor 131.
In this embodiment, a catching groove (not shown) is further provided on the main wiper lever 111 for bypassing the cam 121 when the main wiper is swung. Since the sub wiper lever 112 is disposed inside the main wiper lever 111 and one end of the sub wiper lever 112 abuts against the cam 121, when the sub wiper lever 112 moves along the edge of the cam 121 around the cam shaft 122, the catch groove provided on the main wiper lever 111 allows the main wiper lever 111 to pass around the cam 121 during the swing motion, thereby preventing interference with the cam 121 during the swing motion.
An embodiment of the present invention further provides a vehicle including the wiper blade 10, including: at least one wiper lever 11, at least one drive mechanism 13 and at least one cam mechanism 12; each wiper rod 11 includes: a main wiper rod 111 and an auxiliary wiper rod 112, the auxiliary wiper rod 112 being provided in the main wiper rod 111; each cam mechanism 12 includes a cam 121 and a cam shaft 122, the cam 121 being fixed to the cam shaft 122; the driving mechanism 13 is connected to the head end of the main wiper rod 111 and fitted over the cam shaft 122, one end of the sub-wiper rod 112 abuts against the cam 121, and the other end of the sub-wiper rod 112 is extended outward from the tail end of the main wiper rod 111 by the driving of the cam 121 when the main wiper rod 111 swings.
Like this the brush can be scraped to other regions on the windshield to the outside one end that stretches out of vice wiper rod 112, it is bigger to compare like this in the brush area of scraping of the wiper 10 that only sets up main wiper rod 111, other vision blind areas on the windshield can be scraped to vice wiper rod 112, be favorable to increasing the brush area of scraping of wiper rod 11, through the vehicle that is equipped with above-mentioned wiper 10, can increase the brush area of scraping of wiper rod 11 when the rainy day is gone, make the field of vision scope when driver drives the vehicle broader, be favorable to the car security of traveling. The embodiment of the utility model provides a vehicle, which is used for solving the problems that the traditional windscreen wiper 10 has a small wiping area due to fixed length of the windscreen wiper, the visual field range of a car driver is greatly limited, and the safe driving of the car is not facilitated.
