The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The first embodiment is as follows: referring to fig. 1-4, a foldable wiper includes a movable cylinder 1, a left piston 2, a left connecting portion 3, a left wiper 4, a spring 5, a right piston 6, a right connecting portion 7, and a right wiper 8.

A left limiting block 101 and a right limiting block 102 are fixedly arranged inside the movable cylinder 1.

The interior of the movable cylinder 1 is divided into three sections by a left stopper 101 and a right stopper 102, and the three sections are sequentially divided into a left piston cavity 105, a spring cavity 104 and a right piston cavity 103 from left to right.

The left piston cavity 105 and the right piston cavity 103 are the same in size and symmetrical along the central cross section of the movable cylinder 1, so that the sliding distance between the left piston 2 and the right piston 6 is the same.

The side walls of the left piston cavity 105 and the right piston cavity 103 are made of elastic rubber, so that when the left windshield wiper 4 or the right windshield wiper 8 is limited to swing, the side walls of the left piston cavity 105 and the right piston cavity 103 can keep bending, and the movable cylinder 1 can normally swing.

The movable cylinder 1 is detachably connected with the swing arm of the automobile windshield wiper.

The left piston 2 and the right piston 6 are two parts with the same structure.

The left piston 2 includes a piston rod 201 and a piston head 202.

One end of the piston head 202 is fixedly connected with one end of the piston rod 201.

The piston head 202 of the left piston 2 is positioned in the left piston cavity 105 and is in sliding connection with the inner wall of the left piston cavity 105.

The piston head 202 of the right piston 6 is positioned in the right piston cavity 103 and is in sliding connection with the inner wall of the right piston cavity 103.

The diameter of the piston head 202 is matched with the inner wall of the left piston cavity 105, so that the piston head 202 is effectively prevented from entering the spring cavity 104 and being incapable of realizing limiting

The piston head 202 is always positioned in the movable cylinder 1, so that the piston head 202 slides smoothly, and the problem that the piston head 202 cannot return smoothly due to jumping out of the movable cylinder 1 is effectively prevented, and the wiping efficiency of the wiper is reduced.

The left connecting portion 3 includes a connecting rod 301 and a catch 302.

Connecting rod 301 one end and the other end fixed connection of piston rod 201, the connecting rod 301 other end and buckle 302 upper end fixed connection.

The spring 5 can be extended into the left piston cavity 105 and the right piston cavity 103, and is not only limited in the spring cavity 104, which can ensure that the sliding range of the piston head 202 is wider.

The left wiper 4 and the right wiper 8 are two parts with the same structure.

Left side windshield wiper 4 includes support bar and brush strip, and the brush strip joint is in the support bar lower extreme, support bar and buckle 302 joint, the dismouting and the change of the windshield wiper of being convenient for.

The second embodiment is as follows: the brush strip lateral wall of left windshield wiper 4 and right windshield wiper 8 has set firmly the slide bar, runs into hard filth at left windshield wiper 4 or right windshield wiper 8 and can't be according to original route swing time, and hard filth and slide bar contact effectively avoid brush strip itself and filth contact, and lead to the brush strip to scrape the damage.

The working principle is as follows: left windshield wiper 4 is connected with left piston 2 through left connecting portion 3, right windshield wiper 8 is connected with right piston 6 through right connecting portion 7, be connected through spring 5 between left piston 2 and the right piston 6, left piston 2, right piston 6 and spring 5 are located the left piston chamber 105 of movable cylinder 1 respectively, in right piston chamber 103 and the spring chamber 104, left piston 2 receives the unable spring chamber 104 that gets into of left stopper 101's restriction, right piston 6 receives the unable spring chamber 104 that gets into of right stopper 102's restriction.

The movable cylinder 1 can be dismantled with the car windshield wiper swing arm and be connected, the car windshield wiper swing arm is rotated by car windshield wiper motor drive, left side windshield wiper 4 is swept along with the car windshield wiper swing arm in the swing, when meetting hard filth on the glass, left piston chamber 105 lateral wall is elastic rubber, can bend, the windshield wiper swing arm still continues the swing this moment, left side windshield wiper 4 slides along the filth, 1 normal swing of movable cylinder, right side windshield wiper 8 normally swings, when the filth produces great frictional force to left windshield wiper 4, spring 5 is stretched, left piston 2 slides, reduce the frictional force of left windshield wiper 4 and filth, reduce the possibility that left windshield wiper 4 was scraped badly, right windshield wiper 8 receives the restriction of right stopper 102 because of right piston 6 this moment, can not slide along with the extension of spring 5, make right windshield wiper 8 still swing according to original route.

The operating principle of the right wiper 8 is identical to that of the left wiper 4.

The application provides a new technical thought, the side walls of the left piston cavity 105 and the right piston cavity 103 are both made of elastic materials, the wiper can automatically stop wiping when encountering hard dirt during wiping, the wiper is effectively prevented from being injured, a spring is connected between the left piston 2 and the right piston 6, the left piston 2 and the right piston 6 can slide along the axis of the movable cylinder, the right wiper 8 can normally wipe when encountering hard dirt during wiping of the left wiper 4, the left wiper 4 can normally swing when encountering hard dirt during wiping of the right wiper 8, a left limit block 101 and a right limit block 102 are arranged inside the movable cylinder 1, when one of the left wiper 4 and the right wiper 8 encounters hard dirt and cannot be wiped, the piston connected with the other wiper cannot slide in the movable cylinder 1 along the axis, so that the wiping range and the path of the other wiper are unchanged, and each part has a simple structure, the cost is low.

The foregoing is only a preferred embodiment of the present application; the scope of protection of the present application is not limited thereto. Any person skilled in the art should be able to cover all equivalent or changes within the technical scope of the present disclosure, which is equivalent to the technical solution and the improvement concept of the present disclosure, and the protection scope of the present disclosure.
