[0024] The novel translational wiper of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] In conjunction with the accompanying drawings, a novel translational wiper includes a housing 9, a driving mechanism, a transmission mechanism, a transmission plate 7, a transmission plate 11, and a motor protective cover 15. The driving mechanism includes a motor 1 and a worm gear reducer 14. The output shaft of the motor 1 is connected to the input end of the worm gear reducer 14.

[0026] The transmission mechanism includes a driving sprocket 2, a driven sprocket 3, a support shaft 4 and a chain 5. The driving sprocket 2 is connected to the output end of the worm gear reducer 14. The driven sprocket 3 is movably sleeved on the middle part of the surface of the support shaft 4. The surfaces of the driving sprocket 2 and the driven sprocket 3 are meshed with the chain 5.

[0027] A first connecting rod 6 and a second connecting rod 8 are respectively disposed at both ends of the transmission plate 7. One end of the first connecting rod 6 forms a connection structure with the chain 5 in a direction perpendicular to the running track of the chain 5. The top end of the second connecting rod 8 is connected to a transmission plate 11. A mounting hole 12 for mounting a wiper is provided on the transmission plate 11.

[0028] The cross section of the box body 9 is U-shaped, and arc-shaped protrusions 10 are provided on both sides of the box body 9 . Rollers 17 corresponding to the arc-shaped protrusions 10 are provided on the transmission plate 11 .

[0029] As a preferred implementation scheme of this embodiment, a mounting opening for mounting the motor 1 is opened on one side of the box body 9, and a connecting hole 13 for connecting the motor protective cover 15 is opened at the mounting opening.

[0030] As a preferred implementation scheme of this embodiment, the worm gear reducer 14 includes a reducer housing 1401, a worm 1402, a worm wheel 1403, and an output shaft 1404. A worm 1402 and a worm wheel 1403 are provided in the reducer housing 1401. The worm 1402 and the worm wheel 1403 are meshingly connected. The motor 1 is connected to the worm 1402 through the output shaft. The worm wheel 1403 is provided with an output shaft 1404, and the middle part of the surface of the output shaft 1404 is fixedly sleeved with the driving sprocket 2.
