Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Example one
The embodiment of the invention provides a zooming device.
Fig. 1 is a schematic structural diagram of an embodiment of a zoom apparatus according to the present invention, and as shown in fig. 1, the zoom apparatus of the present embodiment may include a first folding portion 1 and a second folding portion 2. A first mounting hole may be formed in the first folding portion 1, and the camera 3 may be mounted in the first mounting hole. A second mounting hole may be opened in a region of the second fold portion 2 corresponding to the camera 3, and the focus lens 4 may be mounted in the second mounting hole. The focusing lens is configured to perform focus adjustment when receiving a focusing instruction, that is, the focusing lens 4 is a lens capable of changing a focus according to user control information. The first fold 1 and the second fold 2 can be folded relative to each other with a hinge between them.
In an embodiment, after the first folding portion 1 and the second folding portion 2 are folded relatively, in order to prevent the first folding portion 1 and the second folding portion 2 from sliding easily, so as to avoid damaging the terminal, the embodiment may protrude the first mounting hole from the one end of the combination of the camera 3 and the focusing lens 4, and recess the one end of the combination of the focusing lens 4 and the camera 3 in the second mounting hole, so that after the first folding portion 1 and the second folding portion 2 are folded relatively, the camera 3 is embedded in the second mounting hole, thereby realizing that the first folding portion 1 and the second folding portion 2 are relatively fixed after being folded, and are not easy to slide. For example, when first folding portion 1 and second folding portion 2 are as two folding partial screens of display screen respectively, bellied camera 3 is embedded in the second mounting hole, can prevent the displacement of two folding portions more effectively.
It should be noted that the present embodiment is not limited to the above-mentioned manner for preventing the displacement of the two folding portions, for example, an end of the combination of the camera 3 and the focusing lens 4 may be recessed into the first mounting hole, and an end of the combination of the focusing lens 4 and the camera 3 may be protruded out of the second mounting hole. And will not be illustrated one by one here.
In an embodiment, since the light sensing area of the camera 3 is usually disposed at an end that is not combined with the focus lens 4, it can be defined that the other end of the camera 3, i.e. the end of the camera 3 away from the focus lens 4 when the first folding portion 1 and the second folding portion 2 are folded relatively. In order to ensure that the other end of the camera 3 is shielded from light and is not interfered by rear light, the other end of the camera 3 is set to be recessed in the first mounting hole in this embodiment.
In an embodiment, a protective structure, such as a metal ring or a metal frame, may be disposed around an end of the camera 3 combined with the focus lens 4. Wherein the protection structure at least partially protrudes from the surface of the first folded part 1, so as to protect the camera 3 and fasten the camera 3 to the first folded part 1.
In an embodiment, after the first folding portion 1 and the second folding portion 2 are folded relatively, the focusing lens 4 can be combined with the camera 3 to form a new camera, and this embodiment may be defined as a focus-adjustable camera. In this embodiment, the focus lens 4 is configured to adjust the focal length of the focus-adjustable camera when receiving a focus instruction, where the focus instruction may be input by pressing a physical key on the terminal by a user, may also be input by touching a display screen on the terminal by the user, and may also be input in the form of a voice signal through a voice receiving module on the terminal, which is not limited in this embodiment. That is to say, the focus adjusting lens 4 can be used as an extension lens 34 of the camera 3 on the first folding portion 1 in a state that the first folding portion 1 and the second folding portion 2 are folded relatively, and since the focus adjusting lens 4 is a lens 34 capable of changing a focal length according to user operation information, after a user inputs operation information corresponding to a required focal length, the terminal can send a focusing instruction to the focus adjusting lens 4, so that when the focus adjusting lens 4 receives the focusing instruction, the focal length of the focus adjusting lens 4 itself can be changed, and further the focal length of the formed focus-adjustable camera can be adjusted, in this way, the focal length of the camera 3 on the first folding portion 1 can be further adjusted by using the focus adjusting lens 4 under the condition of the original focal length of the camera 3 on the first folding portion 1, which is equivalent to increasing an adjustable range corresponding to the maximum focal length of the camera 3 on the first folding portion 1, the user selects more, and can shoot farther object, has satisfied user's user demand.
In an embodiment, the technical solution of the present invention is described by taking the camera 3 as a unidirectional camera as an example. That is, the camera 3 only includes a camera with one shooting direction, such as only a front camera or only a rear camera, so that the focusing lens 4 is a reverse camera corresponding to the unidirectional camera on the first folding part 1. The image pickup direction of the unidirectional camera on the first folding part 1 is opposite to the image pickup direction of the reverse camera on the second folding part 2, that is, when the first folding part 1 and the second folding part 2 are in an unfolded state, the image pickup direction of the unidirectional camera on the first folding part 1 is opposite to the image pickup direction of the reverse camera on the second folding part 2. That is, if the unidirectional camera only includes the front camera, the backward camera is the rear camera, and if the unidirectional camera only includes the rear camera, the backward camera is the front camera.
In an embodiment, the unidirectional camera on the first folding part 1 may be a rear camera, and the reverse camera on the second folding part 2 may be a front camera. Therefore, the original front camera and the original rear camera in the terminal are arranged separately, no new component is added in the terminal, the front camera and the rear camera can be used separately and in an overlapped mode, the rear camera is equivalent to have a zooming function of twice the camera 3 when the terminal is used in a folded mode, the two 10X cameras are used for example, the zooming function of 100X can be achieved after the camera is used in a combined mode, the high focusing level can be achieved under the condition that the cost is not increased, and a wider focusing range is provided for a user.
In an embodiment, fig. 2 is a view of a structure of a view in a direction a-a and a view in a direction B-B in an unfolded state of fig. 1, and fig. 3 is a combined view of a view in a direction a-a and a view in a direction B-B after folding fig. 1, as shown in fig. 1-3, a front camera (a reverse camera on the second folding part 2) may include a lens barrel 31 and a photosensitive layer 32. The reverse camera, as will be understood by those skilled in the art, may further include a lens 34, a light inlet 33, and the like, and the rear camera (the camera 3 on the first folding portion 1) may also include a lens, a light inlet, a lens barrel, a photosensitive layer, a filter, and the like, wherein the lens, the light inlet, the lens barrel, the photosensitive layer, and the filter of the rear camera are not shown.
In an embodiment, the photosensitive layer 32 in the front camera is disposed in the lens barrel 31 in the front camera and is close to one end combined with the camera 3, a light hole is left between the photosensitive layer 32 in the front camera and the lens barrel 31 in the front camera, or the photosensitive layer 32 in the front camera is a transparent photosensitive layer, so that when the front camera and the rear camera are used separately, the front camera can be ensured to shoot normally, and when the front camera and the rear camera are used in an overlapped manner, light can be ensured to penetrate from the front camera to the rear camera, so that imaging can be performed.
In an embodiment, the camera 3 on the first folding part may also include a first front camera and a first rear camera; correspondingly, the focusing lens comprises a second rear camera corresponding to the first front camera and a second front camera corresponding to the first rear camera; the first front camera and the second rear camera respectively comprise a lens barrel and a photosensitive layer; the photosensitive layer is arranged in the lens barrel, and a light hole is reserved between the photosensitive layer and the lens barrel, or the photosensitive layer is a transparent photosensitive layer. The implementation process of this embodiment is the same as the implementation process when the camera 3 is a unidirectional camera, and is not described herein again.
In an embodiment, a variable transmittance layer may be disposed at one end of the combination of the focus lens 4 on the first folding portion 1 and the camera 3 on the first folding portion 1, and the variable transmittance layer is disposed at one side opposite to the photosensitive surface of the photosensitive layer 32, and is configured to be in a light-transmitting state after the first folding portion 1 and the second folding portion 2 are folded relatively, and to be in a light-non-transmitting state after the first folding portion 1 and the second folding portion 2 are unfolded relatively.
In particular, the variable transmittance layer may include a positive electrode layer, a negative electrode layer, and an electro-variable transmittance layer. The variable transmittance layer is arranged between the positive electrode layer and the negative electrode layer, and is in a non-light-transmitting state when the positive electrode layer and the negative electrode layer are powered on, and is in a light-transmitting state when the positive electrode layer and the negative electrode layer are powered off.
It should be noted that, the variable transmittance layer in the embodiment is not limited to the above structure, and an appropriate variable transmittance layer may be selected according to actual requirements.
The zoom device of this embodiment, after second folded portion 2 is folded to the back of first folded portion 1, set up and can form the adjustable camera of focus with the combination of camera 3 on first folded portion 1 at the focusing lens 4 of second folded portion 2, indirectly increased the length of camera 3 on first folded portion 1 to the adjustable scope that the biggest focus of camera 3 corresponds on first folded portion 1 has been increased, makes the user can shoot farther object. By adopting the technical scheme of the invention, the focal length of the camera 3 can be adjusted on the premise that the length of the camera 3 is limited, and the practicability of the terminal is improved.
In an embodiment, the focus lens 4 may also be a liquid crystal lens 35, so that under different voltage signals, the liquid crystal lens 35 can be made to zoom through different focal lengths, thereby achieving the function of focusing. Fig. 4 is another combination of the folded view in the direction of a-a and the view in the direction of B-B of fig. 1. Fig. 4 differs from fig. 3 in that the front camera is replaced with a liquid crystal lens 35. Equivalently, the camera 3 of the first folding part 1 is a camera conventionally designed in the terminal, for example, the camera 3 can be a front camera and a rear camera combination, and the focusing lens 4 in the second folding part 2 is a structure only having a focusing function, similar to the structure in the current terminal. When unfolded, only the camera 3 of the first folding portion 1 has an imaging function. After being folded, the camera 3 of the first folding part 1 and the focusing lens 4 of the second folding part 2 are combined to achieve a larger focusing function, so that the photosensitive layer 32 and the variable transmittance layer can not be arranged in the liquid crystal lens 35.
In this embodiment, the process of implementing focusing by using the liquid crystal lens 35 is similar to the process of implementing focusing by using the front camera, and please refer to the related description above in detail, which is not repeated herein.
In the present embodiment, the focus lens 4 is not limited to the liquid crystal lens 35 and the front camera, and the lens 34 having a focusing function may be used as the focus lens 4 of the present invention.

The first folding part 1 is a first folding screen; the second folding portion 2 is a second folding screen. The focus lens 4 may be disposed below the second folding screen, or may be disposed in a non-display region of the second folding screen.
Fig. 5 is a schematic structural view of the folded display panel when the focus lens is disposed below the second folding screen, and this solution takes the focus lens 4 as a front camera as an example to describe the technical solution of the present invention. In this embodiment, the front-facing camera is designed to be semi-transparent or fully transparent from the light inlet 33 to the light sensing area, specifically, the light inlet 33 of the front-facing camera may be semi-transparent, and the light sensing area may be fully transparent.
In this embodiment, the light inlet 33 of the front camera may be arranged corresponding to the area of the second folding screen with reference to the schematic diagram of fig. 6. Fig. 6 is a schematic diagram of a display area corresponding to the off-screen camera. As shown in fig. 6, the size of the electrode C of the second folded screen covering the area of the focusing lens 4 is smaller than the size of the electrode D of the second folded screen not covering the area of the focusing lens 4.
