[0030] The specific embodiments of the present application will be described in detail below with reference to the drawings.

[0031] Figure 1 A perspective view of the visual training glasses is shown.

[0032] Figure 2 An exploded view of the visual training glasses is shown.

[0033] Figure 3 A structural view of the support arm is shown.

[0034] As Figure 1 shown, a visual training glasses, comprising: a frame 1, a driven shaft 2, a support arm 3 and a first lens 4; the frame 1 is provided with an open downward containing groove 11 at the bottom; the driven shaft 2 is horizontally arranged in the containing groove 11 and can rotate freely, the driven shaft 2 extends horizontally in the frame 1 through the side wall of the containing groove 11; the support arm 3 is provided with a shaft sleeve 31 at one end and a fixed plate 32 at the other end, and a connecting part 33 between the two ends is provided with a clearance groove 34; the shaft sleeve 31 is fixedly sleeved on the driven shaft 2; the first lens 4 is installed on the fixed plate 32; the clearance groove 34 is arranged to avoid the side wall of the containing groove 11 when the support arm 3 rotates around the driven shaft 2 as the center.

[0035] In the utility model, the frame 1 of the visual training glasses is used for accommodating the driving mechanism of the first lens 4, for example, including the driven shaft 2, the support arm 3 and the like. The driven shaft 2 refers to the shaft that can accept the driving force to rotate. The first lens 4 is a lens with a certain degree, and the specific degree can be set according to the demand of visual training. The first lens 4 can include a single lens or two lenses, and the number of lenses can be set according to the need of monocular training or binocular training.

[0036] When the wearer uses the visual training glasses, the frame 1 is transversely arranged in front of the eyes of the wearer along the length direction, the rotation of the driven shaft 2 drives the rotation of the support arm 3, the rotation of the support arm 3 drives the rotation of the first lens 4, so as to switch the position of the first lens 4, the first lens 4 can be switched between the first position located in front of the line of sight of the wearer and the second position avoiding the front of the line of sight of the wearer, so as to form an adjusting stimulus to the eyes of the wearer, and the purpose of visual training is achieved.

[0037] The frame 1 has the function of supporting and protecting other components, the frame 1 can be a net rack structure or a support structure with a shell, and is preferably a net rack structure inside and a shell outside.

[0038] The opening of the accommodating groove 11 at the bottom of the frame 1 faces downwards and is used for accommodating the transmission mechanism including the driven shaft 2 and the support arm 3 sleeved on the driven shaft 2. By arranging the opening of the accommodating groove 11 downwards, the accumulation of foreign matters and dust on the transmission mechanism can be reduced.

[0039] The driven shaft 2 is transversely arranged in the accommodating groove 11 and can rotate freely, and the transverse direction refers to the direction parallel to the line connecting the eyes of the wearer when the frame 1 is transversely arranged in front of the eyes along the length direction. The driven shaft 2 extends in the frame 1 through the side wall of the accommodating groove 11, and the extended part is used for connecting other driving devices or accepting driving force. At the arrangement position of the driven shaft 2 and the side wall of the accommodating groove 11, a bearing sleeved on the driven shaft 2 can be arranged to realize the free rotation of the driven shaft 2 and reduce the friction between the driven shaft 2 and the side wall of the accommodating groove 11.

[0040] The support arm 3 is used for establishing a rigid connection between the driven shaft 2 and the first lens 4, one end of the support arm 3 is fixedly sleeved on the shaft sleeve 31 of the driven shaft 2, and the shaft sleeve 31 and the driven shaft 2 can be fixed by using a pin or other fixed forms matched in shape, for example, fixed by using a key connection. The fixed sleeving refers to the synchronous movement in the rotation direction and the relative fixation in the axial direction between the driven shaft 2 and the shaft sleeve 31.

[0041] The fixing plate 32 at the other end of the support arm 3 is provided with a mounting position, such as a threaded hole position, a riveting position or the like, of the first lens 4, and is arranged to face the first lens 4 so that the axis of the first lens 4 is located at the visual center of the wearer when the first lens 4 is rotated to the first position along with the driven shaft 2. The fixing plate 32 can be a sheet structure formed at the end of the support arm 3, or a threaded hole position can be directly formed at the end of the support arm 3, and the fixing plate 32 is used as a seat to mount the first lens 4.

[0042] Since the opening of the accommodating groove 11 at the bottom of the frame 1 is downward, when the support arm 3 is rotated along with the driven shaft 2, the middle part of the support arm 3 is in contact with the side wall of the accommodating groove 11 to form an obstacle during the switching of the first lens 4 between the first position and the second position. Based on this, the connecting part 33 between the shaft sleeve 31 and the fixing plate 32 of the support arm 3 is formed with a relief groove 34, and the shape of the relief groove 34 is arranged to allow the support arm 3 to avoid the side wall of the accommodating groove 11 when rotating. Preferably, the relief groove 34 can be U-shaped, or can be arranged in an S shape or other shapes, as long as it can realize the function of avoiding the side wall of the accommodating groove 11.

[0043] The support arm 3 can be integrally formed or assembled by multiple parts, and the utility model preferably is integrally formed.

[0044] The utility model discloses a driven shaft 2 and a support arm 3 of the first lens 4 are arranged in the accommodating groove 11 with a downward opening at the bottom of the frame 1, which can effectively hide the support arm 3 and reduce the hooking of clothes and hair and the accumulation of dust during use.

[0045] Preferably, the difference between the width of the support arm 3 and the width of the accommodating groove 11 is less than 1mm. The width of the support arm 3 refers to the dimension of the support arm 3 along the axis of the driven shaft 2. When the support arm 3 is rotated around the driven shaft 2 as the center, the wider shaft sleeve 31 can provide more stable support for the support arm 3, and the wider relief groove 34 part can provide a certain degree of sealing function for the accommodating groove 11, further reducing the accumulation of external sundries or dust.

[0049] The surface of the shaft sleeve 31 is provided with a limiting part 35 extending radially outward in a sheet shape, and the first stop part 13 and the second stop part 14 are correspondingly arranged in the accommodating groove 11, and the positions of the first stop part 13 and the second stop part 14 are arranged such that when the limiting part 35 abuts against the first stop part 13, the first lens 4 is rotated to the second position, and when the limiting part 35 abuts against the second stop part 14, the first lens 4 is rotated to the first position. Specifically, the shape of the limiting part 35 can be adjusted according to the shape of the first stop part 13 and the second stop part 14, so that the shape of the contact surface of the limiting part 35 matches the shape of the first stop part 13 and the second stop part 14.

[0050] The utility model discloses a stop structure formed by the limiting part 35, the first stop part 13 and the second stop part 14, which can physically limit the rotating position of the support arm 3 and improve the operation stability of the visual training glasses.
