DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0033] like Figures 1 to 3 As shown in , this embodiment is a reading and writing farsightedness device with a connecting rod support structure, including a mirror assembly 11, a semi-transparent and semi-reflective assembly 12 and a cover assembly 13. One end of the semi-transparent and semi-reflective assembly 12 and one end of the cover assembly 13 are both rotatably connected to one end of the mirror assembly 11 around a first axis. The semi-transparent and semi-reflective assembly 12 is located between the mirror assembly 11 and the cover assembly 13. A structure similar to the rotation of a door leaf is formed between the mirror assembly 11, the semi-transparent and semi-reflective assembly 12 and the cover assembly 13.

[0034] In this embodiment, the mirror assembly 11, the semi-transparent and semi-reflective assembly 12 and the cover assembly 13 have an open state and a closed state. In the closed state, the cover assembly 13 and the semi-transparent and semi-reflective assembly 12 are folded and fit onto the mirror assembly 11, occupying very little space. In the open state, the angle between the semi-transparent and semi-reflective assembly 12 and the mirror assembly 11 is 45±15°, preferably 45 degrees; the angle between the cover assembly 13 and the semi-transparent and semi-reflective assembly 12 is 45±15°, preferably 45 degrees.

[0035] In this embodiment, the mirror assembly 11 includes a reflector 111 on the south-facing side of the semi-transparent and semi-reflective assembly 12. The reflector 111 can be a plane mirror, a concave mirror, or a convex mirror. The plane mirror is used to directly reflect light from a pattern or text, the concave mirror is used to reduce the pattern or text to narrow the field of view, and the convex mirror is used to magnify the pattern or text to expand the field of view.

[0036] In this embodiment, the transflective component 12 includes a transflective mirror 121, which is used to reflect light from a target object toward the mirror component 11. The transflective mirror 121 includes a transparent plane mirror and a semi-reflective film. The semi-reflective film is disposed on the side of the transparent plane mirror facing the mirror component 11, or on the side of the transparent plane mirror facing the cover component 13. Preferably, the semi-reflective film is disposed on the side of the transparent plane mirror facing the mirror component 11 to avoid the semi-reflective film directly facing the user, causing visual deviation and other problems.

[0037] In this embodiment, the reading and writing farsightedness device also includes a bracket 14, and the mirror component 11 is arranged on the bracket 14. The other end of the mirror component 11 and the semi-transparent and semi-reflective component 12 are respectively provided with a lighting lamp 15. When in the open state, the space directly below the mirror component 11 and the semi-transparent and semi-reflective component 12 is a placement space for placing target objects such as books and tablets, and the space between the semi-transparent and semi-reflective component 12 and the cover component 13 is a viewing space for viewing the target object. After the target object in the placement space is illuminated by the lighting lamp 15, its light is reflected by the semi-transparent and semi-reflective mirror 121 of the semi-transparent and semi-reflective component 12 to the reflector 111 of the mirror component 11, and then reflected back to the semi-transparent and semi-reflective mirror 121 of the semi-transparent and semi-reflective component 12 and passes through, and is seen through into the viewing space. At this time, the surface pattern or text of the target object can be viewed in the viewing space.

[0038] In this embodiment, the reading and writing farsightedness device also includes a connecting rod support assembly 16, which includes a movable part 161, a first connecting rod 162 and a second connecting rod 163. The movable part 161 is movably arranged on the semi-transparent and semi-reflective assembly 12, and the two ends of the first connecting rod 162 are respectively hinged to the cover assembly 13 and the movable part 161; the two ends of the second connecting rod 163 are respectively hinged to the mirror assembly 11 and the movable part 161; the connecting rod support assembly 16 is used to enable the cover assembly 13 to drive the semi-transparent and semi-reflective assembly 12 to rotate when it is opened, and to support the cover assembly 13 and the semi-transparent and semi-reflective assembly 12 after opening.

[0039] Both ends of the first link 162 and the second link 163 are rotatably hinged. In order to prevent the inconvenience caused by locking during opening or folding, the mounting hole on the movable component 161 for connecting at least one of the first link 162 and the second link 163 is elongated.

[0040] In this embodiment, the transflective assembly 12 includes a track 122 located on the side of the transflective mirror 121, and the movable component 161 is arranged to move on the track 122. The track 122 can be formed on the housing of the transflective assembly 12, or it can be a separate component mounted on the housing, wherein the housing is used to fix the transflective mirror 121, and the track 122 is provided on both sides of the transflective mirror 121.

[0041] The interior of the track 122 is a hollow cavity structure, and the movable part 161 is arranged inside the track 122 for movement. Two long avoidance holes 1221 are opened on the track 122, and the first connecting rod 162 and the second connecting rod 163 pass through the avoidance holes 1221 and are connected to the movable part 161. In addition, the form of the track 122 is not limited to that shown in this embodiment. The form of the track 122 can also be a conventional structure of the prior art such as a groove, a cavity or a ridge.

[0042] In order to reduce the friction between the movable part 161 and the track 122, a roller 164 is provided on the movable part 161, and the movable part 161 is rollingly engaged with the track 122 via the roller 164. In this way, the movable part 161 can move smoothly in the track 122.

[0043] In another embodiment, as an alternative to the roller 164, a rack can be provided on the track along the direction of movement of the movable component 161. The rack can be independent or integrally formed on the track 122. The movable component 161 is provided with a gear that meshes with the rack. This coordination of the rack and gear improves the smoothness of movement of the movable component 161.

[0044] In another embodiment, as an alternative to the roller 164, the semi-transparent and semi-reflective component 12 may also include a screw rod arranged in the same direction as the track 122, and the movable part 161 cooperates with the screw rod. The rotation of the screw rod can drive the movable part 161 to move. The movable part is fixedly connected to a nut sleeved on the screw rod, or the movable part 161 is engaged in the thread groove of the screw rod through a lever, both of which can achieve their purpose. Furthermore, the semi-transparent and semi-reflective component 12 also includes a motor connected to the screw rod, and the motor drives the screw rod to rotate. In this way, the screw rod is driven by the motor to rotate, so that the movable part 161 moves, thereby realizing the automation of opening or closing.

[0045] In this embodiment, the transflective and semi-reflective assembly 12 further includes a limiting structure provided on the side of the track 122, which is used to limit the movement of the movable component 161. The limiting structure is not shown in the figure. For example, the limiting structure can be a movable limiting pin provided on the track 122 and a limiting hole or limiting groove provided on the movable component 161. By inserting the limiting pin into the limiting hole or limiting groove to limit the movable component 161, the movable component 161 can be prevented from sliding on its own, thereby causing the transflective and semi-reflective assembly 12 and the cover assembly 13 to close on their own.

[0046] In this embodiment, the semi-transparent and semi-reflective component 12 and the mirror component 11 are rotatably connected via a damping hinge 17, and the cover component 13 and the mirror component 11 are rotatably connected via a damping hinge 17. This can reduce the supporting burden of the first connecting rod 162 and the second connecting rod 163, and cooperate with each other to achieve stability when opening.

[0047] In this embodiment, when the angle between the transflective assembly 12 and the mirror assembly 11 is 45°, and the angle between the cover assembly 13 and the transflective assembly 12 is 45°, the first connecting rod 162 and the second connecting rod 163 are parallel to each other or on the same straight line. As a result, the forces acting on the movable component 161 by the first connecting rod 162 and the second connecting rod 163 are in opposite directions and parallel to each other or on the same straight line, thereby offsetting each other to prevent the movable component 161 from moving on its own.

[0048] Both the semi-transparent and semi-reflective component 12 and the cover component 13 can be rotated relative to the mirror component 11, which is convenient for opening and use as well as folding and storage. During the opening process, the cover component 13 drives the semi-transparent and semi-reflective component 12 to rotate through the first connecting rod 162. After being fully opened, the first connecting rod 162 can also support the cover component 13 and the second connecting rod 163 can also support the semi-transparent and semi-reflective component 12, thereby increasing the stability in the open state, which is beneficial for users to simulate long-distance reading.

[0049] In this embodiment, in order to reduce the impact of ambient light on the placement space and viewing space when in the open state, it is necessary to install a blackout cloth on the side between the mirror assembly 11 and the semi-transparent and semi-reflective assembly 12, and on the side between the cover assembly 13 and the mirror assembly 11.

[0050] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above embodiments only express several implementation methods of the present application. The description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of this application. It should be pointed out that for ordinary technicians in this field, without departing from the concept of this application, several variations and improvements can be made, which all fall within the scope of protection of this application.
