Description

Technical Field

[0001] The present invention relates to the technical field of vision training, and more particularly to a pair of vision training glasses. Background Art

[0002] Visual training is mainly used in clinical practice to diagnose visual fatigue and conduct visual rehabilitation. It is also of great significance for the intervention of juvenile myopia. The lens is the focuser of the eye, and the muscles that drive the lens to focus include the ciliary muscles. When the ciliary muscles are in a state for a long time, fatigue symptoms will appear, leading to pseudomyopia and myopia. Visual training is a series of targeted exercises and activities to help improve visual function, solve vision problems or relieve visual fatigue. Eye muscle training can enhance the coordination and strength of the eye muscles to improve the movement ability and stability of the eyes.

[0003] The reverse mirror, also known as a double-sided mirror or butterfly mirror, is a tool for visual training and inspection. The two rows of lenses of the reverse mirror are positive and negative. The positive mirror can reduce the stimulation of accommodation, while the negative mirror can increase the stimulation of accommodation. Through the repeated training of positive and negative mirrors, the adjustment sensitivity of the ciliary muscles is exercised, making the eyes less prone to fatigue and the degree of myopia slowly deepened. Therefore, it is helpful for the prevention and control of myopia. During training, keep a distance of about 40 cm between the eyes and the vision card, look at the first sight mark on the vision card through the positive lens of the reverse mirror, and quickly turn the reverse mirror after seeing it clearly, and look at the second sight mark through the negative lens. After seeing it clearly, quickly turn the reverse mirror again, and look at the third sight mark through the positive lens, and repeat this process. However, there are many inconveniences in the use of the reverse mirror, such as uneven switching speed between positive and negative lenses, inaccurate focusing, easy fatigue in the hand-held posture, and affected training results.

[0004] In order to solve the above problems, Chinese invention patent CN217186915U discloses a visual training device, including a shell, a lens plate and a transmission structure. The shell is provided with an installation cavity, and the shell is provided with viewing holes for matching the left and right eyes. The lens plate is rotatably arranged in the installation cavity, and multiple groups of lenses are installed on the lens plate. The transmission structure is installed on the shell, and the transmission structure is used to drive the lens plate to rotate in the installation cavity so that the viewing hole presents different lens groups. In the above-mentioned visual training device, the lens plate is arranged in the installation cavity of the shell, and the lenses on the lens plate are protected by the shell. During the training process, the lenses will not collide with the corrective glasses or trial glasses frames worn by the user, and will not affect the smoothness of the lens group change. At the same time, the lenses are not easily damaged or contaminated, which can ensure the effect of visual training and improve the life of the visual training device.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

It should also be further understood that the term "and / or" used in the specification of the present invention and the claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0030] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Figure 1 A perspective schematic diagram of vision training glasses is shown.

[0032] Figure 2 An exploded schematic diagram of vision training glasses is shown.

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

[0034] like Figure 1 As shown, a pair of vision training glasses comprises: a frame 1, a driven shaft 2, a support arm 3 and a first lens 4; a receiving groove 11 with an opening facing downward is provided at the bottom of the frame 1; the driven shaft 2 is freely rotatably arranged in the receiving groove 11, and the driven shaft 2 passes through the side wall of the receiving groove 11 and extends in the frame 1 in the horizontal direction; a sleeve 31 is provided at one end of the support arm 3, a fixing plate 32 is provided at the other end, and a clearance groove 34 is provided at the connecting part 33 between the two ends; the sleeve 31 is fixedly sleeved on the driven shaft 2; the first lens 4 is mounted on the fixing plate 32; the clearance groove 34 is arranged so that when the support arm 3 rotates around the driven shaft 2, the clearance groove 34 avoids the side wall of the receiving groove 11.

[0035] In the present invention, the frame 1 of the vision training glasses is used to accommodate the driving mechanism of the first lens 4, for example, including a driven shaft 2, a support arm 3, etc. The driven shaft 2 refers to an axis that can receive a 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 needs of vision training. The first lens 4 can include a single lens or two lenses, and the number of lenses can be set according to the needs of monocular training or binocular training.

[0036] When the wearer uses the vision training glasses, the frame 1 is placed horizontally in front of and above the wearer's eyes along the length direction, and the rotation of the driven shaft 2 drives the support arm 3 to rotate. The rotation of the support arm 3 drives the first lens 4 to rotate, thereby switching its position. The first lens 4 can be switched between a first position located directly in front of the wearer's line of sight and a second position away from the wearer's line of sight, thereby forming an adjustment stimulation for the wearer's eyes and achieving the purpose of vision training.

[0037] The frame 1 has the function of supporting and protecting other components. The frame 1 may be a grid structure or a support structure with an outer shell, preferably a grid structure inside and an outer shell covering the outside.

[0038] The receiving groove 11 with an opening facing downward at the bottom of the frame 1 is used to receive a transmission mechanism including a driven shaft 2 and a support arm 3 sleeved on the driven shaft 2. By arranging the receiving groove 11 with an opening facing downward, the accumulation of foreign debris and dust on the transmission mechanism can be reduced.

[0039] The driven shaft 2 is horizontally mounted in the receiving groove 11 and can rotate freely. The horizontal means that when the wearer places the frame 1 horizontally in front of the eyes along the length direction, the driven shaft 2 is parallel to the line connecting the wearer's eyes. The driven shaft 2 passes through the side wall of the receiving groove 11 and extends in the frame 1. The extended part is used to connect other driving devices or receive driving force. At the mounting position of the driven shaft 2 and the side wall of the receiving groove 11, a bearing sleeved on the driven shaft 2 can be set 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 receiving groove 11.

[0040] The support arm 3 is used to establish a rigid connection between the driven shaft 2 and the first lens 4. One end of the support arm 3 is fixedly sleeved on a sleeve 31 on the driven shaft 2. The sleeve 31 and the driven shaft 2 can be fixed by pins or by other shape-matching methods, such as key connection. The fixed sleeve means that the driven shaft 2 and the sleeve 31 move synchronously in the rotation direction and are relatively fixed in the axial direction.

[0041] The fixing plate 32 at the other end of the support arm 3 is provided with a mounting position for the first lens 4, such as a screw hole position, a riveting position, etc. The orientation of the fixing plate 32 is set so that when the first lens 4 rotates to the first position along with the driven shaft 2, the axis of the first lens 4 is located at the visual center of the wearer. The fixing plate 32 can be a sheet structure formed by processing at the end of the support arm 3, or a screw hole position can be directly opened at the end of the support arm 3, and the fixing plate 32 is used to install the first lens 4.

[0042] Since the receiving groove 11 at the bottom of the frame 1 opens downward, when the support arm 3 rotates with the driven shaft 2, during the process of the first lens 4 switching between the first position and the second position, the middle part of the support arm 3 contacts the side wall of the receiving groove 11 to form an obstruction. Based on this, a clearance groove 34 is formed at the connection part 33 between the shaft sleeve 31 and the fixing plate 32 of the support arm 3, and the shape of the clearance groove 34 is set to enable the connection part 33 to avoid the side wall of the receiving groove 11 when the support arm 3 rotates. Preferably, the clearance groove 34 can be U-shaped, or can be set to other shapes such as S-shaped, as long as it can achieve the function of avoiding the side wall of the receiving groove 11.

[0043] The support arm 3 can be configured to be integrally formed or assembled from multiple parts. In the present invention, the support arm 3 is preferably integrally formed.

[0044] The present invention can effectively hide the support arm 3 by arranging the driven shaft 2 of the first lens 4 and the support arm 3 in the accommodating groove 11 with the bottom opening facing downward of the frame 1, thereby reducing 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 receiving groove 11 is less than 1 mm. The width of the support arm 3 refers to the dimension of the support arm 3 along the axial direction of the driven shaft 2. When the support arm 3 rotates around the driven shaft 2, the wider sleeve 31 can provide more stable support for the support arm 3, and the wider clearance groove 34 can provide a certain degree of sealing function for the receiving groove 11, further reducing the accumulation of external debris or dust.

[0046] Figure 4 An enlarged schematic diagram of the frame receiving slot is shown.

[0047] like Figure 3 As shown, the shaft sleeve 31 is provided with a limiting portion 35 extending along the rotation radius direction of the shaft sleeve 31 .

[0048] like Figure 4 As shown, a first stopper 13 and a second stopper 14 corresponding to the limiting portion 35 are provided in the accommodating groove 11 ; the first stopper 13 and the second stopper 14 are configured to limit the rotation arc of the limiting portion 35 between the first stopper 13 and the second stopper 14 .

[0049] The surface of the shaft sleeve 31 is provided with a sheet-shaped limiting portion 35 extending radially outward, and correspondingly, a first stopper 13 and a second stopper 14 are provided in the accommodating groove 11, and the positions thereof are arranged such that when the limiting portion 35 abuts against the first stopper 13, the first lens 4 rotates to the second position, and when the limiting portion 35 abuts against the second stopper 14, the first lens 4 rotates to the first position. Specifically, the shape of the limiting portion 35 can be adjusted according to the shapes of the first stopper 13 and the second stopper 14 to match the shapes of the contact surfaces of the first and second stopper 14.

[0050] The present invention can physically limit the rotation position of the support arm 3 by providing a stop structure composed of the limit portion 35, the first stop portion 13 and the second stop portion 14, thereby improving the operating stability of the vision training glasses.

[0051] Figure 5 A schematic diagram of vision training glasses including a second lens is shown.

[0052] like Figure 5 As shown, the vision training glasses further include: a second lens 5 detachably mounted on the bottom of the frame 1 through a snap structure or a magnetic structure; when the first lens 4 rotates, there is at least one angle that makes the second lens 5 and the first lens 4 coaxial. The second lens can be set to a lens with a certain degree, including positive and negative degrees, and the specific degree can be set according to the needs of vision training.

[0053] The installation position of the second lens 5 is set so that when the wearer uses the vision training glasses, the second lens 5 always remains at the wearer's visual center. For example, the second lens 5 includes two lenses, each of which is located at the visual center of the wearer's left eye and right eye. The second lens 5 is detachably installed at the bottom of the frame 1 through a snap-on structure or a magnetic structure. When the second lens 5 needs to be replaced, it can be easily disassembled. Among them, the visual center covers 60° above the horizon to 70° below the horizon, and 90° to the left and right of the horizon.

[0054] In order to achieve the purpose of matching training, when the first lens 4 and the second lens 5 work together, the dimensions of the driven shaft 2, the support arm 3, etc. are set to ensure that the two are coaxial. That is, when the first lens 4 rotates to the first position, the first lens 4 is also located at the visual center of the wearer. The second lens 5 is located in the direction of the first lens 4 close to the wearer's eyes.

[0055] Preferably, the accommodating groove 11 is opened in the middle of the bottom of the frame 1, and the snap-fit ​​structure or magnetic structure for installing the second lens 5 is arranged at the lens mounting position 12 on both sides of the accommodating groove 11 at the bottom of the frame 1, so that the connecting mechanisms of the first lens 4 and the second lens 5 can avoid each other and do not interfere with each other.

[0056] Figure 6A schematic diagram of the internal structure of the framework is shown.

[0057] Figure 7 A schematic diagram of vision training glasses including temples and nose pads is shown.

[0058] like Figure 6 and Figure 7 As shown, a power supply 6, a controller 7, a motor 8 and a driving shaft 9 are arranged in the frame 1; the power supply 6 is connected to the controller 7; the motor 8 is connected to the controller 7; the driving shaft 9 is connected to the output shaft of the motor 8, and the end of the driving shaft 9 is rotatably mounted in the frame 1; the driving shaft 9 is connected to the driven shaft 2, and it is arranged that the driving shaft 9 and the driven shaft 2 rotate synchronously.

[0059] The power supply 6, controller 7, and motor 8 in the frame 1 are fixed by the frame 1, for example, they are clamped and fixed by the grid structure in the frame 1. Preferably, the motor 8 is wrapped with a flexible material and mounted in the frame 1. One end of the driving shaft 9 is connected to the output shaft of the motor 8, and the other end is supported by the frame 1 and can rotate freely. For example, the other end of the driving shaft 9 is connected to a bearing and fixed by the grid structure in the frame 1, and the frame 1 bears the gravity of the driving shaft 9.

[0060] The power supply 6 and the motor 8 are symmetrically arranged so that the center of gravity of the frame 1 is substantially coincident with the geometric center. In the present invention, the power supply 6 and the motor 8 are components with a relatively large weight in the frame 1, and their positions are arranged to be symmetrical. The symmetrical arrangement means that they are symmetrical in weight relative to the geometric center of the frame 1, so as to maintain a relatively stable center of gravity of the frame 1 as a whole. The center of gravity substantially coincides with the geometric center means that after the frame 1 is loaded with internal components, the deviation between its center of gravity and its geometric center is less than 20%, less than 10%, or less than 5%.

[0061] The power supply 6 is used to provide power to the controller 7 and the motor 8, and can be a lithium-ion battery, a nickel-metal hydride battery or a solar cell, etc. The controller 7 can be set as a circuit board containing a chip and other functional components. The controller 7 has the function of automatically controlling or controlling the start, stop, forward rotation, reverse rotation and running time of the motor 8 after receiving instructions, which can be realized by using existing technology and will not be described in detail in the present invention.

[0062] The driving shaft 9 and the driven shaft 2 extending into the frame 1 may be connected coaxially through a coupling or through gear meshing, so that the driving shaft 9 drives the driven shaft 2 .

[0063] When the wearer uses the vision training glasses, the power supply 6 is turned on, and the start and stop, forward rotation, reverse rotation and running time of the motor 8 are controlled by the controller 7, so that the driving shaft 9 can be driven to rotate, and the driving shaft 9 drives the driven shaft 2 to rotate, thereby driving the support arm 3 and the first lens 4 to rotate.

[0064] The connection between the driving shaft 9 and the driven shaft 2 can be in any of the following ways:

[0065] Optionally, a main gear is provided on a fixed sleeve on the driving shaft 9; a secondary gear is processed on the surface of the driven shaft 2 or a secondary gear is provided on the fixed sleeve; the main gear is meshed with the secondary gear teeth or the main gear is meshed with the secondary gear.

[0066] Optionally, the driving shaft 9 is processed with main gear teeth on its surface; the driven shaft 2 is processed with secondary gear teeth on its surface or the fixed sleeve is provided with a secondary gear; the main gear teeth mesh with the secondary gear teeth or the main gear teeth mesh with the secondary gear.

[0067] Preferably, Figure 3 and Figure 4 As shown, the controller 7 includes a contact switch 15 ; a paddle 36 is disposed on the sleeve 31 ; the paddle 36 is disposed corresponding to the contact switch 15 , and when the first lens 4 rotates, there is at least one angle that enables the paddle 36 to trigger the contact switch 15 .

[0068] The outer surface of the sleeve 31 is provided with a paddle 36 extending in the radial direction, and the shape of the paddle 36 matches the contact switch 15. The position of the paddle 36 can be set correspondingly according to the position of the contact switch 15. Preferably, the position of the paddle 36 and the contact switch 15 is set to be triggered when the first lens 4 rotates to the first position. The corresponding setting means that when the sleeve 31 rotates, the contact switch 15 is located on the rotation track of the paddle 36.

[0069] like Figure 6 As shown, a display screen 16 is provided on the frame 1, and the display screen 16 is connected to the controller 7; an interface 17 and a button 18 are provided on the frame 1, and the interface 17 and the button 18 are connected to the controller 7; an audio player 19 is provided on the frame 1, and the audio player 19 is connected to the controller 7; and temples 101 and nose pads 102 are provided on the frame 1.

[0070] Specifically, the display screen 16 is connected to the controller 7 and can output the status or prompt information of the vision training glasses. The interface 17 and the button 18 can be used for external charging and inputting instructions. The audio player 19 can be controlled by the controller 7 to output prompt sounds.

[0071] The temples 101 and the nose pads 102 are arranged such that when the wearer uses the vision training glasses, there is at least one rotation angle so that the first lens 4 is located at the wearer's visual center. Preferably, the nose pads 102 are wrapped by a flexible material.

[0072] According to the vision training glasses provided above, the present invention can effectively hide the support arm and reduce hooking and dust accumulation by arranging the transmission mechanism such as the driven shaft and the support arm of the first lens in the receiving groove with the opening facing downward at the bottom of the frame. By setting the width of the support arm to be similar to the width of the receiving groove, the sealing can be further improved, and dust can be reduced from entering the frame from the gap. By setting a stopper structure, the rotation position of the support arm can be physically limited, thereby improving the running stability of the vision training glasses. By setting a detachable structure of the second lens, it is convenient to replace the second lens. By setting the first lens and the second lens to cooperate, the effectiveness of vision training can be improved. By setting a power supply and a controller to control the motor to drive the active shaft and drive the driven shaft, the automatic rotation of the first lens can be realized. By setting the meshing connection between the active shaft and the driven shaft, the active shaft can output stable power to the driven shaft, thereby improving the rotation stability of the first lens. By setting a contact switch to cooperate with the paddle, the first lens can be rotated and positioned to feedback toward the controller. By wrapping the motor with a flexible material, the motor vibration can be absorbed, thereby improving the stability of the vision training glasses. By setting a display screen, an interface, a button and an audio player, the wearer's experience can be improved. By providing temples and nose pads, the effect of convenient wearing can be achieved.
