[0017] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0019] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0020] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0021] This embodiment discloses an electronic visual aid. Figure 1 , including a panel portion and a supporting portion, wherein the supporting portion includes a connecting rod 2 and a base 3, and the two ends of the connecting rod 2 are rotatably connected to the panel portion and the base 3 respectively, and through relative rotation, the panel portion, the base 3 and the connecting rod 2 can be in a folded storage form or an unfolded form.

[0022] The panel portion includes a supporting panel 11 and a display panel 12. The supporting panel 11 includes a front end and a rear end. The rear end of the supporting panel 11 is connected to the connecting rod 2. In the expanded state, the connecting rod 2 is in a vertical state. The rear end of the supporting panel 11 is connected to the top of the connecting rod 2. The supporting panel 11 can be flipped up and down with its rear end as the rotation center; the display panel 12 is hinged to the front end of the supporting panel 11. The display panel 12 can be stacked on the supporting panel 11 and can be flipped up and down with the front end of the supporting panel 11 as the rotation center.

[0023] The base 3 is connected to the bottom end of the connecting rod 2. The base 3 is a flat structure and is used to be placed flat on any plane to form a support for the entire electronic visual aid. The base 3 also includes a front end and a rear end. The connecting rod 2 is located at the rear end of the base 3. Therefore, in the unfolded state, the display part is located directly above the base 3, so that the center of gravity of the electronic visual aid is maintained in the middle, and the overall stability will not tip over.

[0024] The bottom of the support panel 11 is provided with an image acquisition unit, referring to Figure 2The image acquisition unit includes but is not limited to a camera 113 and an LED light 114. In the expanded state, the angle of the support panel 11 is adjusted so that the camera 113 and the LED light 114 face a position within the range of the base 3. The object to be viewed, such as newspapers, books, etc., is placed on the base 3, and the content information on the object can be acquired by the camera 113. A display screen is provided on the display panel 12, and the content acquired by the camera 113 is displayed on the display screen. The user can directly view the relevant content through the display panel 12, and can view the content more clearly by moving the object or directly moving and enlarging the content on the display screen, which is very friendly to the user experience of the visually impaired.

[0025] Specifically, the support panel 11 is recessed to form a seating groove for embedding the display panel 12, and the front end of the seating groove forms a straight edge with a rounded cross-section. The front end cross-section of the display panel 12 also has the same rounded corners, so that the front end of the display panel 12 and the front end of the seating groove form a mating installation, and the rounded edges make the rotation between the display panel 12 and the support panel 11 smooth.

[0026] A rotating shaft structure is disposed inside the front end of the support panel 11 to connect the display panel 12 to the support panel 11 . The user can directly act on the display panel 12 to lift and flip it from the support panel 11 .

[0027] When the display panel 12 is completely embedded in the placement groove, the display panel 12 and the support panel 11 are arranged parallel and stacked, and the inner wall of the placement groove forms an abutment surface that fits the back of the display panel 12. In the unfolded form of the electronic viewer, the display panel 12 displays content at this time, and the display direction of the display panel 12 can be adjusted directly by adjusting the angular position of the support panel 11 and the connecting rod 2. This method is similar to the existing desktop viewer, which has only one panel. Although it is easy to use, due to the limited image acquisition angle and range of the camera 113 at the bottom, the optimal angle of the panel is within a small range, and exceeding it will significantly affect the visual effect. Therefore, this method requires the user's line of sight to be higher than the panel of the electronic viewer when in use, that is, the user is standing or the electronic viewer is placed in a lower position, which can easily cause user fatigue or be inconvenient for user operation. Visually impaired people usually have inconvenience in movement due to their visual impairment, so this method is not very friendly to the visually impaired.

[0028] Therefore, the present embodiment sets a double-panel form of a display panel 12 and a support panel 11, and the display panel 12 can be rotated out of the placement groove relative to the support panel 11, and the display panel 12 and the support panel 11 form a certain adjustable angle. In this way, the display range of the display panel 12 is greatly increased. While keeping the angle of the support panel 11 fixed so that the camera 113 has a better collection position, the user can freely adjust the angle of the display panel 12 according to the actual usage scenario, position, sitting posture, and body habits, so as to have a clearer viewing and avoid reflection, unclear vision, and head-down strain. It is particularly suitable for the case where the user's line of sight is close to the height of the electronic visual aid, or the user's line of sight is lower than the electronic visual aid, that is, sitting posture, the visual aid is placed on a higher desktop, etc., which is very friendly to the visually impaired.

[0029] The support panel 11 is also provided with a magnet 111 for adsorbing and fixing the display panel 12. The magnet 111 preferably adopts a sheet structure. The magnet 111 is fixedly arranged on the inner wall of the placement groove. When the display panel 12 and the support panel 11 are in a retracted state, the back of the display panel 12 fits against the magnet 111 to form an adsorption effect, so that the display panel 12 is sufficiently stable and will not be easily opened during use. It can be opened by applying a certain external force when the user needs to use it.

[0030] The display panel 12 is also provided with a gasket 121 on the front side to prevent users from collision. The gasket 121 is installed at the peripheral frame of the display panel 12 and protrudes forward. When abnormal tipping occurs, it plays a certain role in protecting the display screen of the display panel 12.

[0031] A groove 112 is disposed on the side of the support panel 11 , and the groove 112 is connected to the side of the placement slot, so that the user can conveniently insert his / her hand into the groove to lift up the display panel 12 .

[0032] In one embodiment, a movable telescopic rod 21 is further provided at the top of the connecting rod 2, and one end of the telescopic rod 21 forms a connecting end for connecting to the connecting rod 2, and the connecting end is a rotating shaft connection, so that the telescopic rod 21 can rotate relative to the connecting rod 2, and a telescopic camera is provided at the end of the telescopic rod 21. When the telescopic rod 21 rotates relative to the connecting rod 2, the telescopic camera can capture images with a wider viewing angle other than the area below the visual aid.

[0033] The specific structure of the telescopic rod 21 may refer to the structure disclosed in a visual aid image acquisition device in Chinese utility model patent CN216414399U, and will not be described in detail here.

[0034] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
