Description

Technical Field

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

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

[0003] However, the adjustable focal length range of the telephoto shooting module is relatively small, making it difficult to achieve a larger focal length adjustment, and making it difficult to capture clear scenes at a greater 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, 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 the area of ​​the first folding part corresponding to the first through hole. 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 where the first surface of the first folding portion is located in the first through hole, the first through hole is connected to the second through hole, and since the photosensitive component is arranged in the first folding portion, the rotatable light guide is located in the area corresponding to the first through hole in the first folding portion, and therefore, the first posture and the 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 posture 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 photographing 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 in conjunction with 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 a telephoto camera module, which has a relatively long lens focal length and is suitable for capturing details of distant objects and photographing inaccessible subjects. However, the internal space of smartphones is limited, resulting in a relatively small adjustable focal length range of the telephoto camera module, making it difficult to achieve a larger focal length adjustment, and difficult to capture clear images of objects at a longer distance.

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

[0022] In practical applications, the terminal device 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 (UMPC), netbooks, PDAs (Personal Digital Assistants), 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 that are intelligently designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories.

[0024] Wearable devices are not just hardware devices, but also realize powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include those with full functions, large size, and can realize complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0025] Figure 1 to Figure 3 The folding part of the embodiment of the present application is shown in a schematic diagram of the structure in different states. Figure 1 to Figure 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 arranged in the frame area of ​​the foldable frame 103. Here, the foldable frame 103 is arranged at the edge of the first folding portion 101 except the edge connected to the second folding portion 102, and at the edge of the second folding portion 102 except the edge connected to the first folding portion 101.

[0027] For example, Figure 3 As shown, the shape of 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, the fourth side of the first folding portion 101 is rotatably connected to the first side of the second folding portion 102, and the frame can be arranged around the first side and the third side of the first folding portion 101 and the second side to the fourth side of the second folding portion 102.

[0028] like Figure 1 to Figure 3 As shown, the first surface A1 of the first folding portion of the embodiment of the present application is opposite to the second surface A2 of the first folding portion, and the first surface B1 of the second folding portion is opposite to the second surface B2 of the second folding portion. 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 in FIG. 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 part can be regarded as the back of the first folding part 101, the first surface B1 of the second folding part can be regarded as the back of the second folding part 102, the second surface A2 of the first folding part can be regarded as the front of the first folding part 101, and the first surface B1 of the second folding part can be regarded as the front of the second folding part 102. In this case, when the imaging system is applied to a folding screen mobile phone, the front of the first folding part 101 and the front of the second folding part 102 can be regarded as the large screen of the folding mobile phone in the unfolded state, and the back of the first folding part 101 and the back of the second folding part 102 can be regarded as the back of the folding mobile 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 sides of the first folding portion 101, and the second through hole H2 can pass through the front and back sides 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 foldable frame 103 while penetrating the first folding portion 101. Similarly, the second through hole H2 can penetrate the foldable frame 103 while penetrating the second folding portion 102. In this way, a large 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. The first screen 104 can be arranged 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 can be arranged on the first surface A1 of the first folding portion. Of course, the second screen 105 can also be arranged on the first surface B1 of the second folding portion.

[0033] When the imaging system of the embodiment of the present application is applied to a folding 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 folding portion 102. One end of the second through hole H2 located on the back of the second folding portion 102 can be compatible with the position of the telephoto lens Ha.

[0034] Figure 4 FIG. 1 is a schematic diagram showing an imaging principle of an imaging system in an embodiment of the present application in an unfolded state. 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 in 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 in 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 switch 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 It can be seen that when the imaging system is in the unfolded state, the rotatable light guide 106C is used to transmit the light L1 transmitted by the first lens 106A to the photosensitive component 106D in the first posture. Here, the first posture may refer to that the light guide surface of the rotatable light guide 106C is opposite to the end of the first surface A1 of the first through hole H1 located in the first folding portion. The relative here is not strictly relative, but it is only necessary to ensure that the light guide surface of the rotatable light guide 106C can receive the light L1 transmitted by 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 opened by the first folding part 101 and the first through hole H1 opened by the second folding part 102 are parallel. Since the rotatable light guide 106C and the photosensitive component 106D are both located in the first folding part 101, and the first lens 106A is located in the area where the first surface A1 of the first folding part is located in the first through hole H1, the rotatable light guide 106C cannot transmit the light transmitted by the second lens 106B to the photosensitive component 106D no matter how it rotates, but can only transmit the light transmitted by the first lens 106A that directly enters the first through hole H1 to the photosensitive component 106D, thereby realizing ordinary 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 FIG. 2 shows another imaging principle schematic diagram of the imaging system in the folded state of 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 a 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 the light L2 transmitted by the first lens 106A is transmitted to the photosensitive component 106D through the rotatable light guide 106C, thereby realizing ordinary telephoto imaging.

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

[0041] By comparing the two imaging methods, we can find that Figures 4 to 6 As shown, the optical paths 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 are 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, so as to shoot 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 the reflected light of the ambient light.

[0042] In one possible implementation, Figure 2 and Figure 3As shown, the imaging system of the 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 arranged on the second surface A2 of the first folding part and the second surface B2 of the second folding part, and the second screen 105 is arranged on the first surface B1 of the second folding part. It should be understood that the first screen 104 is a folding screen, which can be implemented by a flexible screen or other combination screens.

[0043] like Figure 4 As shown, when the imaging system is in the unfolded state, the photosensitive component 106D can form a first image upon 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-imaging.

[0044] like Figure 5 and Figure 6 As shown, when the imaging system is in the folded state, when the photosensitive component 106D receives the light transmitted by the first lens 106A, it forms a second image, and transmits it to the second screen 105 to display a preview image of the second image, thereby realizing front-end imaging. When the photosensitive component 106D receives the light transmitted by the second lens 106B, it forms a third image, and transmits it to the third screen to display a preview image of the third image, thereby realizing rear-end imaging.

[0045] Exemplarily, the embodiment of the present application may further include a control module, which may be electrically connected to the rotatable light guide 106C, the first screen 104, and the second screen 105. When the control module is used to detect a request for the first telephoto imaging mode, the rotatable light guide may be controlled to be in a first posture. When a request for the second telephoto imaging mode is detected, the rotatable light guide may be controlled to be in a second posture. Here, 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 a telephoto imaging mode or an ultra-telephoto imaging mode in the camera application on the second screen, and 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 an alternative approach, Figure 7FIG. 2 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 disposed on the inner wall of the rotating base away from the first folding portion 101. The rotating base is disposed on the inner wall of the first folding portion 101, and the refractive element 202 may be located at Figure 6 The area in 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 of the embodiment of the present application may be a prism. In the 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 the 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 region 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 be used as a sealing strip for the side of the first folding part 101 and the side of the second folding part 102, therefore, the inner side of the foldable frame 103 can be used as the inner wall of the first folding part 101, and when the rotating base is arranged 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 part 101. For example, when the first through hole H1 passes through the first surface A1 of the first folding part and the second surface A2 of the first folding part, the rotating base is arranged on the side of the foldable frame 103 located on the first folding part 101 away from the second folding part 102.

[0052] In an optional manner, the rotating base of the embodiment of the present application includes a first driving assembly and a rotating assembly arranged on the first driving assembly, the first driving assembly is used to drive the rotating assembly to rotate. The first driving assembly is arranged on the inner wall of the first folding portion, and the refractive element is arranged 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. Fig. 9 FIG. 1 is a schematic diagram showing the assembly structure of the first drive assembly of an embodiment of the present application. Figure 8 and Fig. 9As shown, the first driving assembly includes a stator ring 2011A, a flexible circuit board 2011B and a driving coil 201a arranged on the flexible circuit board 2011B, and the flexible circuit board 2011B is arranged on the outer wall of the stator ring 2011A. The flexible circuit board 2011B can be an annular circuit board, which can be sleeved on the stator ring 2011A.

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

[0055] Fig.10 FIG. 1 is a schematic diagram showing the electromagnetic relationship between the magnetic member and the drive coil in an embodiment of the present application. Fig.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. Fig. 9 The dotted line shown in the figure) is located in the plane Fig.10 The YZ plane is shown.

[0056] like Fig.10 As shown, when the current direction of the driving coil 201a is Fig.10 When the current in the YZ plane shown in FIG. 2 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 Fig.10 When the YZ plane shown flows clockwise, the magnet can be subjected to the Ampere force along the positive direction of the Y axis, and the magnetic member 201b can drive the rotor to rotate along the second direction b. It can be seen that the embodiment of the present application can control the rotation direction of the rotor by adjusting the current direction of the driving coil 201a, thereby controlling the prism to switch 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, and 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 above-mentioned adjustable focal length lens can be used as a focusing component of the first lens and the second lens to achieve fine adjustment of small-range focus. Here, the adjustable focal length lens includes a third lens 106b and a second driving component 106c, and the second driving component 106c is connected to the third lens 106b, and the second driving component 106c is used to adjust the distance between the third lens 106b and the photosensitive chip 106a.
