[0026] This embodiment discloses an image acquisition device, on which a camera assembly is provided. The image acquisition device can be used to be installed on some electronic display devices to acquire image information through the camera assembly so that the image information can be displayed on the electronic display device. In addition, the image acquisition device and the electronic display device are movably installed, so that the camera assembly can acquire image information in multiple directions around the electronic display device over a wide range.

[0027] The image acquisition device in this embodiment is preferably installed on an electronic viewer product. The electronic viewer is mainly used for daily use by visually impaired people. It mainly includes a base for placing information carriers such as books and newspapers, a display screen for displaying images, and a camera for acquiring image information in the direction of the base. By adding the image acquisition device to the electronic viewer, the image acquisition range of the electronic viewer can be effectively improved. The user can not only see the content on the base on the display screen, but also see distant information through the image acquisition device.

[0028] Specifically, refer to Figure 1 The image acquisition device includes a first rod body 1 and a second rod body 2, one end of the first rod body 1 is provided with a first rotating shaft 11, and the first rod body 1 is connected to the electronic visual aid through the first rotating shaft 11, so that the first rod body 1 can rotate relative to the electronic visual aid with the first rotating shaft 11 as the rotation center.

[0029] Reference Figure 2 , 3 4. The other end of the first rod body 1 is connected to the second rod body 2 via a rotating structure, and the rotating structure includes a second rotating shaft 4. The outer circumference of the second rotating shaft 4 is respectively sleeved with a first fixing portion 41 and a second fixing portion 42, and the first fixing portion 41 and the second fixing portion 42 are respectively fixedly connected to the first rod body 1 and the second rod body 2, and the connection method includes but is not limited to screw fixing, etc. For the rotating structure, the first fixing portion 41 is fixed to the second rotating shaft 4, and the second fixing portion 42 can rotate relative to the second rotating shaft 4, or, the first fixing portion 41 and the second fixing portion 42 can both rotate around the second rotating shaft 4, so that the second rod body 2 can rotate relative to the first rod body 1.

[0030] Axial caps and nuts are respectively disposed at two axial ends of the second rotating shaft 4 to prevent the first fixing portion 41 and the second fixing portion 42 from falling out in the axial direction.

[0031] By arranging the axial direction of the second rotating shaft 4 to be perpendicular to the length direction of the first rod body 1 or the second rod body 2 , the movable direction of the second rod body 2 is within the left-right swing range relative to the first rod body 1 .

[0032] The first rod body 1 and the second rod body 2 are matched in an interlaced manner, and a first matching portion and a second matching portion are formed on the first rod body 1 and the second rod body 2, respectively. Matching planes for relative abutment are formed on the first matching portion and the second matching portion, respectively. A first arc surface 12 and a second arc surface 21 are formed at the end of the first matching portion and the end of the second matching portion, respectively. The center of the first arc surface 12 and the center of the second arc surface 21 both fall on the axis of the second rotating shaft 4. Further, the first rod body 1 and the second rod body 2 are respectively provided with limiting arc surfaces for matching with the second arc surface 21 and the first arc surface 12. The matching of the arc surfaces ensures that there will be no excessive gap on the surface of the image acquisition device, and the degree of integration is high. In addition, the two ends of the limiting arc surface are arranged to abut the second rod body 2 after it is rotated to the left or right by a certain angle to prevent it from further rotating, and limit the movement range of the second rod body 2 to a certain angle range to avoid damaging the internal wiring due to excessive rotation, or causing collision with the visual aid.

[0033] The camera assembly is arranged at the end of the second rod body 2, and the camera assembly includes a shell 31, a camera 32 and a third rotating shaft 33. The camera 32 is arranged in the shell 31, and the third rotating shaft 33 is connected to the second rod body 2, so that the shell 31 can rotate relative to the second rod body 2 to adjust the direction of the camera 32.

[0034] For the image acquisition device, its movable range includes the rotation direction of the first rotating shaft 11, the rotation direction of the second rotating shaft 4 and the rotation direction of the third rotating shaft 33, so that the camera 32 can move and collect in multiple directions in three-dimensional space relative to the electronic visual aid, thereby fully collecting information in the surrounding environment.

[0035] Reference Figure 3 The end of the second rod body 2 is in the shape of a cylinder with an opening, and the third rotating shaft 33 is inserted into the second rod body 2. The third rotating shaft 33 adopts a damping rotating shaft and has a certain rotation damping to improve the stability and accuracy of the rotation between the camera assembly and the second rod body 2, and provide excellent rotation feedback; or, the third rotating shaft 33 is an ordinary rotating shaft, and a rubber ring 34 is provided between the third rotating shaft 33 and the second rod body 2. The rubber ring 34 is made of rubber material, and the rubber ring 34 is respectively against the outer peripheral wall of the third rotating shaft 33 and the inner peripheral wall of the second rod body 2, thereby being able to produce a certain damping on the rotation of the third rotating shaft 33.

[0036] The camera 32 is connected to a wire 5, which passes through the interior of the second rod body 2 and the first rod body 1 and then enters the visual aid. In order to carry out reasonable wiring and avoid the internal wire 5 being twisted, folded, clamped, etc. during the movement between the first rod body 1 and the second rod body 2, which may cause damage, the interior of the second rotating shaft 4 in this embodiment is hollow, and the first rod body 1 and the second rod body 2 are both provided with space for wiring. Two openings that are connected to the internal hollow space of the second rotating shaft 4 are provided on the outer wall of the second rotating shaft 4, and the two openings are respectively connected to the wiring space in the first rod body 1 and the wiring space in the second rod body 2.

[0037] Further, as the most preferred, refer to Figure 4 and Figure 5 In this embodiment, the second rotating shaft 4 is hollow and through along the axial direction, and the two openings are respectively located at the axial ends of the second rotating shaft 4. The openings at the two ends are respectively connected with the internal space of the first rod body 1 and the internal space of the second rod body 2. The wire 5 is passed through the two openings to pass through the second rotating shaft 4. In this way, no matter how the second rod body 2 moves, the wire 5 will only bend in a small range, avoiding excessive twisting and clamping, and will not damage the wire 5.

[0038] Similarly, the first rotating shaft 11 is also hollow for the wire 5 to pass through and enter the visual aid.

[0039] 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.
