The two reels 32 are assembled at the left and right ends of the frame body 21 of the goggle frame 20 and respectively covered by the side covers 23 of the goggle frame 20. The bottom ends of the two reels 32 respectively have two opposite engaging recesses 33 (as shown in FIGS. 2, 5 and 6). The soft sheet 34 is made of a light-transmissive material, a part of the soft sheet 34 abuts on the outer surface of the lens 31, and two opposite ends of the soft sheet 34 are respectively wound around the two reels 32 (as shown in FIGS. 1 and 3). In this way, one of the reels 32 can roll up the soft sheet 34 when it is rotated, so that the soft sheet 34 moves laterally relative to the lens 31. During the lateral movement of the soft sheet 34, the other reel 32 will be synchronized to rotate.

(20) The control assembly 40 comprises a casing 41, a ratchet wheel 50, a pawl 55, a rope wheel 56, an elastic member 59, a pulling rope 60, a finger rod 61, a transmission plate 62, and a bottom cover 65, as shown in FIGS. 2 and 4.

(21) The casing 41 comprises a holder base 42 and a top cover 43. The top cover 43 is provided on the top surface of the holder base 42 and forms an accommodation space 44 between the holder base 42 (see FIG. 5). The top cover 43 has a shaft hole 45 that communicates with the accommodation space 44 vertically, and a first fastening portion 46 at the top side thereof. The first fastening portion 46 of the casing 41 is fastened to one fastening groove 22 of the frame body 21 of the goggle frame 20, as shown in FIGS. 2 and 5, so that the two are assembled together in a detachable manner. The holder base 42 has a rope hole 47 located at one side thereof and laterally disposed in communication with the accommodation space 44, and a wheel shaft 48 disposed therein corresponding to the shaft hole 45. The wheel shaft 48 has a first engaging groove 49.

(22) The ratchet wheel 50 is mounted in the accommodation space 44, having a top side thereof provided with a transmission shaft 51. The transmission shaft 51 of the ratchet wheel 50 is inserted through the shaft hole 45 of the casing 41, and provided with two opposite engaging protrusions 52. The engaging protrusions 52 of the ratchet wheel 50 are detachably fastened to the engaging recesses 33 of one reel 32, so that the ratchet wheel 50 can drive the connected reel 32 to rotate. In addition, as shown in FIG. 8a, the outer perimeter of the ratchet wheel 50 is provided with an outer ring tooth portion 53, and the inner perimeter of the ratchet wheel 50 is provided with an inner ring tooth portion 54. The pawl 55 is set in the holder base 42 of casing 41 and is unidirectionally engaged with the outer ring tooth portion 53 of the ratchet wheel 50, as shown in FIG. 4 and FIG. 11a, to limit the ratchet wheel 50 to unidirectional rotation.

(23) The rope wheel 56 is mounted in the accommodation space 44 and rotatably coupled to the wheel shaft 48 of the casing 41. The rope wheel 56 has a driving protrusion 57 located at a top side thereof, and a second engaging groove 58 located at one lateral side thereof.

(24) The elastic member 59 in this embodiment is a coil spring. The elastic member 59 has an inner end 592 thereof fastened to the first engaging groove 49 of the wheel shaft 48 of the casing 41 and an outer end 594 thereof fastened to the second engaging groove 58 of the rope wheel 56, for providing a spring force to drive the rope wheel 56 for reverse rotation (as shown by the arrow in FIG. 11b).

(25) The pulling rope 60 is inserted through the rope hole 47 of the casing 41 with one end thereof disposed in the accommodation space 44 and connected to the rope wheel 56 and an opposite end thereof disposed outside the accommodation space 44 and connected to the finger rod 61, so that on the one hand, the pulling rope 60 can be pulled by the finger rod 61 to drive the rope wheel 56 to rotate forward (as shown by the arrow in FIG. 10b), on the other hand, the pulling rope 60 can be reversed by the rope wheel 56 (as shown by the arrow in FIG. 11b) to carry the finger rod 61 in direction toward the casing 41.

(26) The transmission plate 62 is provided between the ratchet wheel 50 and the rope wheel 56, and has a transmission recess 63. The transmission recess 63 of the transmission plate 62 is engaged with the driving protrusion 57 of the rope wheel 56, so that the transmission plate 62 can be synchronized with the rope wheel 56. In addition, the transmission plate 62 has two opposite ratchet portions 64. When the rope wheel 56 rotates forward in the direction of the arrow shown in FIG. 10b, the ratchet portion 64 of the transmission plate 62 will engage the inner ring tooth portion 54 of the ratchet wheel 50, as shown in FIG. 10a, so that the ratchet wheel 50 rotates with the rope wheel 56. When the rope wheel 56 rotates reversely in the direction of the arrow as shown in FIG. 11b, the ratchet portion 64 of the transmission plate 62 will not engage the inner ring tooth portion 54 of the ratchet wheel 50, as shown in FIG. 11a, so that the ratchet wheel 50 does not rotate with the rope wheel 56.

(27) The top surface of the bottom cover 65 is provided with a second fastening portion 66. The second fastening portion 66 of the bottom cover 65 is fastened to the other fastening groove 22 of the frame body 21 of the goggle frame 20, as shown in FIG. 2 and FIG. 6, so that the two are assembled together in a detachable manner.

(28) It can be known from the above, before starting to use, adjust the position of the control assembly 40 according to the dominant hand of the wearer. When adjusting, first detach the two side covers 23, and then release the fastening relationship between casing 41 and frame body 21 of the goggle frame 20 and the fastening relationship between the bottom cover 65 and the frame body 21 of the goggle frame 20 in order to detach the control assembly 40 and the bottom cover 65. Then choose the installation position of the two according to the dominant hand of the wearer. For example, if the wearer's dominant hand is the right hand, as shown in FIG. 12, assemble the control assembly 40 at the right end of the goggle frame 20 and the bottom cover 65 at the left end of the goggle frame 20 through the casing 41. On the contrary, if the wearer's dominant hand is the left hand, as shown in FIG. 7, assemble the control assembly 40 at the left end of the goggle frame 20 and the bottom cover 65 at the right end of the goggle frame 20 through the casing 41. After determining the installation position of the two, reinstall the two side covers 23 and start using.

(29) During the use, when the outer surface of the soft sheet 34 is dirty and affects the sight, the wearer pulls the finger rod 61 by his or her dominant hand, as shown in FIG. 9, so that the finger rod 61 drives the rope wheel 56 to rotate forward in the direction of the arrow shown in FIG. 10b through the pulling rope 60. At this time, the rope wheel 56 will, on the one hand, roll the elastic member 59 to accumulate the elastic restoring force of the elastic member 59, and on the other hand, drive the ratchet wheel 50 to rotate together through the transmission plate 62 (as shown in FIG. 10a). Then, the ratchet wheel 50 drives the connected reel 32 to rotate together. With this, the reel 32 driven by the ratchet wheel 50 can start to roll the soft sheet 34, so that the soft sheet 34 moves laterally relative to the lens 31. On the one hand, the dirty part of the soft sheet 34 is rolled up, and on the other hand, the clean part of the soft sheet 34 is released. In this way, the soft sheet 34 can always be kept clean in the part corresponding to lens 31. Release the finger rod 61 after removing dirt. At this time, the rope wheel 56 will be subject to the resetting force of the elastic member 59 to rotate reversely in the direction of the arrow shown in FIG. 11b, and at the same time, the pulling rope 60 will be rolled up. The pulling rope 60 will further drive the finger rod 61 to reset until one end of the finger rod 61 abuts against the holder base 42 of the casing 41 (as shown in FIGS. 8a and 8b). As for the ratchet wheel 50, it is restricted by pawl 55 at this time and remains stationary.

(30) In summary, the goggle 10 of the present invention allows the wearer to change the position of the control assembly 40 according to his or her dominant hand, so that the wearers of different dominant hands can operate smoothly. During operation, the soft sheet 34 is quickly scrolled by using the cooperation of the ratchet wheel 50 and the pawl 55, so that the wearer can maintain a good line of sight during outdoor high-speed sports.

(31) Of course, there can be many other embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should fall within the protection scope of the claims attached to the present invention.
