Description

Technical Field

[0001] The present application relates to the field of heat dissipation technology, and in particular to an imaging system and terminal equipment. Background Art

[0002] Currently, smartphones are generally equipped with telephoto shooting modules. The focal length of the telephoto shooting module is relatively long, which is suitable for capturing details of distant scenes and photographing subjects that are difficult to approach.

[0003] However, the focal length adjustment range of the telephoto shooting module is relatively small, making it difficult to achieve a larger focal length adjustment, and it is difficult to take clear photos of scenes at a farther distance. Summary of the Invention

[0004] According to one aspect of the present application, an imaging system is provided, comprising: a first folding portion, a second folding portion, and a camera assembly, wherein a side edge of the first folding portion is rotatably connected to a side edge of the second folding portion, and the camera assembly comprises a rotatable light guide, a first lens, a second lens, and a photosensitive component;

[0005] The first folding portion has a first through hole, and the second folding portion has a second through hole, the first through hole and the second through hole are connected when the imaging system is in a folded state, and the first surface of the first folding portion and the first surface of the second folding portion are in the same plane when the imaging system is in an unfolded state;

[0006] The first lens is arranged in an area where the first surface of the first folding part is located in the first through hole, the second lens is arranged in an area where the first surface of the second folding part is located in the second through hole, the photosensitive component is arranged in the first folding part, and the rotatable light guide is located in an area corresponding to the first through hole in the first folding part. The rotatable light guide is used to transmit the light transmitted by the first lens to the photosensitive component in a first posture when the imaging system is in a folded state, and to transmit the light transmitted by the second lens to the photosensitive component in a second posture.

[0007] According to another aspect of the present application, a terminal device is provided, comprising the imaging system of the technical solution of the present application.

[0008] In one or more technical solutions provided in the present application, the first lens is arranged in an area of ​​the first surface of the first folding portion that is located within the first through hole, the first through hole is connected to the second through hole, and since the photosensitive component is arranged within the first folding portion, the rotatable light guide is located in an area of ​​the first folding portion that corresponds to the first through hole, and therefore, the first posture and second posture of the rotatable light guide can be switched by rotating the rotatable light guide. When the rotatable light guide is in the first posture, the light transmitted by the first lens can directly enter the first through hole, and the light transmitted by the first lens is transmitted to the photosensitive component through the rotatable light guide; when the rotatable light guide is in the second posture, the light transmitted by the second lens can enter the first through hole through the second through hole, and then the light transmitted by the second lens is transmitted to the photosensitive component through the rotatable light guide.

[0009] As can be seen from the above, the optical paths of the light transmitted by the first lens and the light transmitted by the second lens received by the photosensitive component of the present application are different. Therefore, the present application can achieve a wide range of optical focus adjustment by switching the posture of the rotatable light guide, thereby shooting distant objects with a longer focal length.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In the related art, smartphones are generally equipped with telephoto camera modules. These modules have a relatively long focal length, making them suitable for capturing details in distant scenes and difficult-to-reach subjects. However, due to the limited internal space of smartphones, the telephoto camera module's focal length adjustment range is relatively small, making it difficult to achieve a wider focal length adjustment, and thus difficult to capture clear images of distant scenes.

[0021] In response to the above problems, an embodiment of the present application provides a terminal device, which may include an imaging system that can achieve a wide range of optical focus adjustment, thereby photographing distant objects with a longer focal length.

[0022] In practical applications, the terminal devices of the exemplary embodiments of the present disclosure may be various foldable terminals or electronic devices with display functions, such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), and wearable devices based on augmented reality (AR) and / or virtual reality (VR) technologies.

[0023] For example, when the terminal device is a wearable device, the wearable device can also be a general term for wearable devices developed by applying wearable technology to intelligently design everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories.

[0024] Wearable devices are more than just hardware; they achieve powerful functionality through software support, data exchange, and cloud-based interaction. Broadly speaking, these smart wearables include those that are full-featured, large in size, and can function completely or partially independently of a smartphone, such as smartwatches and smart glasses. They also encompass those that focus on a specific application and require integration with other devices, such as smartphones, such as various smart wristbands and smart jewelry for vital sign monitoring.

[0025] Figures 1 to 3 Schematic diagram of the structure of the folding portion of the embodiment of the present application in different states. Figures 1 to 3 As shown, the imaging system of the embodiment of the present application includes a first folding portion 101, a second folding portion 102 and a camera assembly, and the side edge of the first folding portion 101 is rotatably connected to the side edge of the second folding portion 102.

[0026] In practical applications, such as Figure 3 As shown, the imaging system of the embodiment of the present application may further include a foldable frame 103, and the first folding portion 101 and the second folding portion 102 are provided in the frame area of ​​the foldable frame 103. Here, the foldable frame 103 is provided at the edge of the first folding portion 101 excluding the connection with the second folding portion 102, and at the edge of the second folding portion 102 excluding the connection with the first folding portion 101.

[0027] For example, Figure 3 As shown, the first folding portion 101 and the second folding portion 102 of the embodiment of the present application can be rectangular or square. For example, if the fourth side of the first folding portion 101 is rotatably connected to the first side of the second folding portion 102, the frame can be set around the first and third sides of the first folding portion 101 and the second to fourth sides of the second folding portion 102.

[0028] like Figures 1 to 3 As shown, the first surface A1 of the first folding portion and the second surface A2 of the first folding portion are opposite to each other, and the first surface B1 of the second folding portion and the second surface B2 of the second folding portion are opposite to each other. Figure 2 As shown, the first surface A1 of the first folding portion and the first surface B1 of the second folding portion are in the same plane when the imaging system is in the unfolded state, and as shown Figure 3 As shown, the second surface A2 of the first folding portion and the second surface B2 of the second folding portion are in the same plane when the imaging system is in the unfolded state.

[0029] For example, Figure 2 and Figure 3As shown, the first surface A1 of the first folding portion can be considered the back of the first folding portion 101, the first surface B1 of the second folding portion can be considered the back of the second folding portion 102, the second surface A2 of the first folding portion can be considered the front of the first folding portion 101, and the first surface B1 of the second folding portion can be considered the front of the second folding portion 102. In this case, when the imaging system is applied to a foldable screen mobile phone, the front of the first folding portion 101 and the front of the second folding portion 102 can be considered the large screen of the foldable phone in the unfolded state, while the back of the first folding portion 101 and the back of the second folding portion 102 can be considered the back of the foldable phone in the unfolded state.

[0030] like Figure 3 As shown, the first folding portion 101 of the embodiment of the present application has a first through hole H1, and the second folding portion 102 has a second through hole H2. The first through hole H1 can pass through the front and back of the first folding portion 101, and the second through hole H2 can pass through the front and back of the second folding portion 102.

[0031] like Figure 3 As shown, the first through hole H1 of the embodiment of the present application may be located at an edge of the first folding portion 101 away from the second folding portion 102 , and the second through hole H2 may be located at an edge of the second folding portion 102 away from the first folding portion 101 .

[0032] For example, Figure 3 As shown, when the imaging system includes a foldable frame 103, the first through hole H1 can penetrate the first folding portion 101 and the foldable frame 103 at the same time. Similarly, the second through hole H2 can penetrate the second folding portion 102 and the foldable frame 103 at the same time. In this way, a larger space can be reserved for the first folding portion 101 and the second folding portion 102 to arrange other components. For example, Figure 2 and Figure 3 As shown, the imaging system further includes a first screen 104 and a second screen 105. The first screen 104 is a folding screen and can be disposed on the second surface A2 of the first folding portion and the second surface B2 of the second folding portion. The second screen 105 can be disposed on the first surface A1 of the first folding portion. Of course, the second screen 105 can also be disposed on the first surface B1 of the second folding portion.

[0033] When the imaging system of the present embodiment is used in a foldable screen mobile phone, conventional lenses, such as a telephoto lens Ha, a main camera lens Hb, and a wide-angle lens Hc, are also provided on the back of the second foldable portion 102. The second through hole H2 is located on one end of the back of the second foldable portion 102 to be compatible with the location of the telephoto lens Ha.

[0034] Figure 4 FIG. 1 shows a schematic diagram of an imaging principle of an imaging system in an expanded state according to an embodiment of the present application. Figure 4As shown, the camera assembly of the embodiment of the present application may include a first lens 106A, a second lens 106B, a rotatable light guide 106C, and a photosensitive component 106D. The first lens 106A is disposed in an area where the first surface A1 of the first folding portion is located within the first through hole H1, and the second lens 106B is disposed in an area where the first surface B1 of the second folding portion is located within the second through hole H2.

[0035] like Figure 4 As shown, in this case of the embodiment of the present application, the light L1 transmitted by the first lens 106A enters the first through hole H1, and the photosensitive component 106D is arranged in the first folding portion 101. For example, the rotatable light guide 106C can realize the switching between the first posture and the second posture by rotating, and no matter whether the rotatable light guide 106C is in the first posture or the second posture, the photosensitive component 106D can be arranged on the output light path of the rotatable light guide 106C.

[0036] from Figure 4 As can be seen, when the imaging system is in the unfolded state, the rotatable light guide 106C is configured to transmit light L1 transmitted from the first lens 106A to the photosensitive component 106D in a first posture. This first posture may refer to the light-guiding surface of the rotatable light guide 106C being opposite the end of the first through hole H1 located on the first surface A1 of the first folded portion. This "opposite" is not strictly opposite, but rather ensures that the light-guiding surface of the rotatable light guide 106C can receive the light L1 transmitted from the first lens 106A and transmit it to the photosensitive component 106D.

[0037] like Figure 4 As shown, when the imaging system is in the unfolded state, the central axes of the first through hole H1 defined by the first folding portion 101 and the first through hole H1 defined by the second folding portion 102 are parallel. Since the rotatable light guide 106C and the photosensitive component 106D are both located within the first folding portion 101, and the first lens 106A is located in the area where the first surface A1 of the first folding portion is located within the first through hole H1, no matter how the rotatable light guide 106C rotates, it cannot transmit light transmitted by the second lens 106B to the photosensitive component 106D. Instead, it can only transmit light transmitted by the first lens 106A that directly enters the first through hole H1 to the photosensitive component 106D, thereby achieving normal telephoto imaging.

[0038] Figure 5 A schematic diagram showing an imaging principle of the imaging system of an embodiment of the present application in a folded state is shown. Figure 6 FIG2 shows another imaging principle diagram of the imaging system in the folded state according to an embodiment of the present application. Figure 5 and Figure 6As shown, the first through hole H1 and the second through hole H2 are connected when the imaging system is in the folded state. For example, the first through hole H1 and the second through hole H2 can be coaxial in the imaging system. In this case, the imaging system has two possible imaging modes.

[0039] In the first imaging mode, Figure 5 As shown, the rotatable light guide 106C is used to transmit the light L2 transmitted by the first lens 106A to the photosensitive component 106D in the first posture when the imaging system is in the folded state. In this case, the light L2 transmitted by the first lens 106A can directly enter the first through hole H1 and be transmitted to the photosensitive component 106D by the rotatable light guide 106C, thereby achieving normal telephoto imaging.

[0040] In the second imaging mode, Figure 6 As shown, the rotatable light guide 106C is used to transmit light L3 transmitted from the second lens 106B to the photosensitive component 106D in a second posture when the imaging system is in the folded state. The second posture here can mean that when the imaging system is in the folded state, the light guiding surface of the rotatable light guide 106C is opposite the end of the second through hole H2 located on the first surface B1 of the second folded portion. In this case, the light L3 transmitted from the second lens 106B can enter the first through hole H1 through the second through hole H2, and then the rotatable light guide 106C transmits the light transmitted from the second lens 106B to the photosensitive component 106D, thereby achieving long-distance telephoto imaging.

[0041] By comparing the two imaging methods, we can find that Figures 4 to 6 As shown, the optical path of the light transmitted by the first lens 106A and the light transmitted by the second lens 106B received by the photosensitive component of the embodiment of the present application is different. Therefore, the embodiment of the present application can achieve a wide range of optical focus adjustment by switching the posture of the rotatable light guide 106C, thereby photographing distant objects with a longer focal length. It can be seen that the first lens 106A and the second lens 106B of the embodiment of the present application can together form a telephoto lens group to achieve ordinary telephoto imaging and long-distance telephoto imaging. In addition, the light transmitted by the first lens 106A and the light transmitted by the second lens 106B in the embodiment of the present application can be reflected light from ambient light.

[0042] In one possible implementation, Figure 2 and Figure 3As shown, the imaging system of this embodiment of the present application further includes a first screen 104 and a second screen 105 electrically connected to the photosensitive component 106D. The first screen 104 is provided on the second surface A2 of the first folding portion and the second surface B2 of the second folding portion, and the second screen 105 is provided on the first surface B1 of the second folding portion. It should be understood that the first screen 104 is a folding screen, which can be implemented as a flexible screen or other combination of screens.

[0043] like Figure 4 As shown, when the imaging system is in the expanded state, the photosensitive component 106D can form a first image when receiving the light transmitted by the first lens 106A, and transmit it to the first screen 104 to display a preview image of the first image, thereby realizing post-type imaging.

[0044] like Figure 5 and Figure 6 As shown, when the imaging system is in the folded state, the photosensitive component 106D can form a second image upon receiving light transmitted by the first lens 106A, and transmit the second image to the second screen 105 for displaying a preview of the second image, thereby implementing front-facing imaging. When the photosensitive component 106D receives light transmitted by the second lens 106B, it can form a third image and transmit the third image to the third screen for displaying a preview of the third image, thereby implementing rear-facing imaging.

[0045] For example, embodiments of the present application may further include a control module that may be electrically connected to the rotatable light guide 106C, the first screen 104, and the second screen 105. The control module may be configured to control the rotatable light guide to a first position upon detecting a request for a first telephoto imaging mode. Upon detecting a request for a second telephoto imaging mode, the rotatable light guide may be controlled to a second position. The first telephoto imaging mode may be a normal telephoto imaging mode, and the second telephoto imaging mode may be an ultra-telephoto imaging mode.

[0046] Exemplarily, when the imaging system is in the unfolded state, the user can select the telephoto imaging mode in the camera application on the first screen, and the camera application can send the selection result to the control module as a request for the first telephoto imaging mode, so that the control module can control the rotatable light guide to be in the first posture according to the selection result.

[0047] Exemplarily, when the imaging system is in a folded state, the user can select telephoto imaging mode or super telephoto imaging mode in the camera application on the second screen. The camera application can send the selection result to the control module as a request for the second telephoto imaging mode, so that the control module can control the rotatable light guide to be in the first posture or the second posture according to the selection result.

[0048] In one alternative, Figure 7FIG. 1 shows a schematic structural diagram of a rotatable light guide member according to an embodiment of the present application. Figure 7 As shown, the rotatable light guide 200 may include a rotating base 201 and a refractive element 202 provided on the inner wall of the rotating base away from the first folding portion 101. The rotating base is provided on the inner wall of the first folding portion 101, and the refractive element 202 may be located at Figure 6 The area within the first folded portion 101 shown corresponds to the first through hole H1 .

[0049] like Figures 4 to 7 As shown, the refractive element 202 in the embodiment of the present application may be a prism. In a first posture, the prism may face the direction of the first lens 106A, and the angle between the reflective surface of the prism and the optical axis of the first lens 106A may be 45°. In a second posture, the prism may face the direction of the second lens 106B, and the angle between the reflective surface of the prism and the optical axis of the second lens 106B may be 45°.

[0050] In practical applications, such as Figure 3 As shown, the imaging system of the embodiment of the present application further includes a foldable frame 103 , the first folding portion 101 and the second folding portion 102 are arranged in the inner area of ​​the foldable frame 103 , and the rotating base is arranged on the inner side of the foldable frame 103 .

[0051] For example, Figure 3 As shown, the foldable frame 103 of the embodiment of the present application can serve as a sealing strip for the side edges of the first folding portion 101 and the second folding portion 102. Therefore, the inner side of the foldable frame 103 can serve as the inner wall of the first folding portion 101, and when the rotating base is provided on the inner side of the foldable frame 103, the folding element can be located in the area corresponding to the first through hole H1 in the first folding portion 101. For example, when the first through hole H1 passes through the first surface A1 of the first folding portion and the second surface A2 of the first folding portion, the rotating base is provided on the side of the foldable frame 103 located on the first folding portion 101 away from the second folding portion 102.

[0052] In an optional embodiment, the rotating base includes a first driving assembly and a rotating assembly provided on the first driving assembly, wherein the first driving assembly is used to drive the rotating assembly to rotate. The first driving assembly is provided on the inner wall of the first folding portion, and the refractive element is provided on the rotating assembly.

[0053] For example, Figure 8 An exploded schematic diagram of a rotating base according to an embodiment of the present application is shown. Figure 9 FIG1 shows a schematic diagram of the assembly structure of the first drive assembly of the embodiment of the present application. Figure 8 and Figure 9As shown, the first drive assembly includes a stator ring 2011A, a flexible circuit board 2011B, and a drive coil 201a provided on the flexible circuit board 2011B. The flexible circuit board 2011B is provided around the outer wall of the stator ring 2011A. The flexible circuit board 2011B can be an annular circuit board that can be sleeved on the stator ring 2011A.

[0054] like Figure 8 and Figure 9 As shown, in the embodiment of the present application, the surface of the flexible circuit board 2011B provided with the driving coil 201a contacts the outer wall of the stator ring 2011A, which has an opening 201c. In this case, the driving coil 201a is located within the opening 201c. Simultaneously, the rotating assembly includes a mover 2012 and a magnetic member 201b located on the outer wall of the mover 2012. The mover 2012 is located within the stator ring 2011A, and the magnetic member 201b contacts the driving coil 201a. The mover 2012 can be a mover ring located within the stator ring 2011A. The base of the prism can be adhered to the mover ring using a colloid.

[0055] Figure 10 Schematic diagram showing the electromagnetic relationship between the magnetic member and the drive coil in the embodiment of the present application. Figure 10 As shown, the N pole and S pole of the magnetic member 201b of the embodiment of the present application can be distributed along the circumference of the rotor ring. Figure 9 The dotted line shown in the figure) is located in the plane Figure 10 The YZ plane is shown.

[0056] like Figure 10 As shown, when the current direction of the driving coil 201a is Figure 10 When the YZ plane shown in FIG2 flows counterclockwise, the magnet can be subjected to the Ampere force along the negative direction of the Y axis, and the magnetic member 201b can drive the rotor to rotate along the first direction a; when the current direction of the driving coil 201a is in Figure 10 When the YZ plane shown flows clockwise, the magnet can be subjected to an Ampere force along the positive direction of the Y axis, and the magnetic member 201b can drive the rotor to rotate in the second direction b. Thus, in the embodiment of the present application, by adjusting the direction of the current flowing through the drive coil 201a, the direction of rotation of the rotor can be controlled, thereby controlling the transition of the prism between the first posture and the second posture.

[0057] In summary, the imaging system of the embodiment of the present application can make full use of the spatial increment generated by the first folding part and the second folding part from the unfolded state to the folded state, increase the optical path of the light sensed by the photosensitive component 106D, so as to achieve a wide range of optical focus adjustment, thereby achieving longer-distance focal length shooting.

[0058] It should be noted that if Figures 4 to 6As shown, the photosensitive component 106D of the embodiment of the present application includes a photosensitive chip 106a and an adjustable focus lens. The adjustable focus lens and the photosensitive chip 106a are arranged in the first folding portion along a direction away from the rotatable light guide 106C.

[0059] The adjustable focus lens can serve as a focusing assembly for the first and second lenses, enabling fine-tuning of focus within a small range. The adjustable focus lens includes a third lens 106b and a second drive assembly 106c, which is connected to the third lens 106b and configured to adjust the distance between the third lens 106b and the photosensitive chip 106a. The second drive assembly can be a drive motor.
