DETAILED DESCRIPTION

[0031] 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.

[0032] Example 1

[0033] The first embodiment provides a reading and writing device for long-sightedness, comprising a mirror assembly 11, a transflective assembly 12, and a cover assembly 13. One end of the transflective 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, and the transflective assembly 12 is located between the mirror assembly 11 and the cover assembly 13.

[0034] In order to achieve electric rotation, the reading and writing farsightedness device also includes a motor 14 fixed on the mirror assembly 11, and the motor 14 is transmission-connected to the cover assembly 13. The motor 14 is used to drive the cover assembly 13 to rotate. A connecting component 16 is also provided between the cover assembly 13 and the semi-transparent and semi-reflective assembly 12. The connecting component 16 is used to enable the cover assembly 13 to drive the semi-transparent and semi-reflective assembly 12 to rotate.

[0035] Compared with the prior art, in the reading and writing farsightedness device of this embodiment, the semi-transparent and semi-reflective component 12 and the cover component 13 can be rotated relative to the mirror component 11, so as to be convenient for unfolding and use as well as folding and storage; driven by the motor 14 to realize automation, it can achieve the effect of simulating long-distance reading at close range when unfolded and used, and it also has the folding and storage advantages of the folding mechanism, which is beneficial for users to simulate long-distance reading and convenient storage.

[0036] In this embodiment, the motor 14 and the cover assembly 13 are driven by a gear transmission mechanism, which includes a passive gear 151 and two transmission gears 152, wherein the passive gear 151 is fixed on the cover assembly 13, and the two transmission gears 152 are arranged on the mirror assembly 11 and can rotate and mesh with each other. The axis of the passive gear 151 is located on the first axis, and the passive gear 151 is meshed with the transmission gear 152.

[0037] Exemplarily, the passive gear 151 has a special structure. The passive gear 151 includes a semicircular portion with teeth and a fixed portion. The teeth of the semicircular portion are engaged with the transmission gear 152. The fixed portion can cooperate with the cover assembly 13 to fix the passive gear 151. A fixing hole is provided on the fixing portion, and fixation can be achieved by passing a screw or pin through the fixing hole. Since the cover assembly 13 does not need to rotate in a circle, its rotation angle will not exceed 180 degrees. The passive gear 151 with this structure is already applicable.

[0038] In this embodiment, the motor 14 is fixedly installed inside the mirror assembly 11. The motor 14 is used to drive the transmission gear 152. In order to facilitate the layout of the motor 14, the output shaft of the motor 14 is connected to the worm 153. The worm 153 is engaged with the transmission gear 152. The worm 153 and the transmission gear 152 constitute a worm gear 153 structure. The worm gear 153 structure can increase the driving force of the motor 14.

[0039] In this embodiment, the cover assembly 13 is rotationally connected to the mirror assembly 11 via a first rotating shaft 131. There are two first rotating shafts 131, which are coaxially arranged with the driven gear 151, and their axes are both located on the first axis. Thus, the motor 14 drives the transmission gear 152, which drives the driven gear 151 to rotate, so that the mirror assembly 11 can rotate about the first rotating shaft 131. Specifically, the first rotating shaft 131 is fixed to the cover assembly 13 and is rotationally connected to the mirror assembly 11.

[0040] In this embodiment, the transflective component 12 is rotationally connected to the mirror component 11 via a second rotation shaft 121. The second rotation shaft 121 is coaxially arranged with the first rotation shaft 131 and both are located on the first axis. Specifically, the second rotation shaft 121 is fixed to the transflective component 12 and is rotationally connected to the mirror component 11.

[0041] In this embodiment, a limiting structure is provided between the cover assembly 13 and the semi-transparent and semi-reflective assembly 12. The limiting structure is used to limit the position of the semi-transparent and semi-reflective assembly 12 relative to the cover assembly 13. The limiting structure includes a first limiting protrusion 132 provided on the cover assembly 13 and a second limiting protrusion 123 provided on the semi-transparent and semi-reflective assembly 12. The first limiting protrusion 132 and the second limiting protrusion 123 abut against each other to limit the position of the semi-transparent and semi-reflective assembly 12. Due to the limiting effect of the limiting structure, the semi-transparent and semi-reflective assembly 12 is prevented from falling by itself when in the open state.

[0042] In addition, an avoidance groove 112 is provided on the mirror assembly 11 for avoiding the first limiting protrusion 132 and the second limiting protrusion 123 , so that after being folded and stored, the first limiting protrusion 132 and the second limiting protrusion 123 can be accommodated in the avoidance groove 112 .

[0043] In this embodiment, the connecting member 16 is used to enable the cover assembly 13 to pull the semi-transparent and semi-reflective assembly 12 to rotate. The length of the connecting member 16 can determine the rotation angle of the semi-transparent and semi-reflective assembly 12. The connecting member 16 is a foldable multi-section connecting rod or a pull rope. One end of the connecting member 16 is connected to the side of the cover assembly 13, and the other end is connected to the side of the semi-transparent and semi-reflective assembly 12.

[0044] In this embodiment, the reading and writing telescopic device further includes a bracket 17 , the mirror assembly 11 is disposed on the bracket 17 , and the other ends of the mirror assembly 11 and the semi-transmissive and semi-reflective assembly 12 are respectively provided with an illumination lamp 18 .

[0045] In this embodiment, the mirror assembly 11, the semi-transparent and semi-reflective assembly 12 and the cover assembly 13 include 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 retracted into the mirror assembly 11.

[0046] In the open state, the angle between the translucent and semi-reflective components 12 and the mirror component 11 is 45±15°, preferably 45 degrees; the angle between the cover component 13 and the translucent and semi-reflective components 12 is 45±15°, preferably 45 degrees. In the open state, the space directly below the mirror component 11 and the translucent and semi-reflective components 12 is a placement space for placing the target object, and the space between the translucent and semi-reflective components 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 18, its light is reflected by the translucent and semi-reflective components 12 to the mirror component 11, and then reflected back to the translucent and semi-reflective components 12, and then sees through to the viewing space; at this time, the surface pattern or text of the target object can be viewed in the viewing space.

[0047] 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.

[0048] 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.

[0049] In this embodiment, the transflective component 12 includes a transflective mirror 122, which is used to reflect light from a target object toward the mirror component 11. The transflective mirror 122 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.

[0050] In the reading and writing telescopic device in this embodiment, the cover assembly 13 is opened or closed electrically. When it is opened, it can achieve the effect of simulating long-distance reading at a close distance. At the same time, it also has the advantage of folding and storing when closed, which is beneficial for users to simulate long-distance reading and convenient storage.

[0051] 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.
