[0049] Smart terminals can be implemented in various forms. For example, the smart terminals described in this application may include smart terminals such as mobile phones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0050] An optical conversion device and a smart terminal provided in this application are described below with reference to the accompanying drawings.

[0051] Currently, many electronic devices have camera modules with multiple cameras, such as wide-angle, telephoto, and macro cameras, to meet diverse user shooting needs. However, current single cameras have limited functionality and cannot achieve macro, wide-angle, or telephoto shooting effects.

[0052] Therefore, the optical conversion device provided in this application embodiment achieves the switching of different objective lenses through an objective lens conversion component, superimposing the effects of the camera with different objective lenses to meet different shooting needs. This design can provide multiple optical characteristics in a single camera system, enabling a single camera to adapt to various shooting scenarios and achieve different video effects, increasing versatility. Compared to equipping each shooting need with a separate camera, this application helps to save costs.

[0053] refer to Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides an optical conversion device, including: a base 10 and an objective lens conversion assembly 20. The base 10 includes a camera aperture 11. (Refer to...) Figure 2 and Figure 9 As shown, the camera hole 11 is used to correspond to the position of the camera 31.

[0054] refer to Figure 2 , Figure 3 and Figure 4As shown, the objective lens conversion assembly 20 is movably arranged relative to the base 10, the objective lens conversion assembly 20 comprises a movable frame 21 and at least two different objective lenses 22 arranged on the movable frame 21, the movable frame 21 is movable relative to the base 10 to switch the positions of the different objective lenses 22 corresponding to the imaging hole 11.

[0055] The optical conversion device provided by the embodiment of the present application switches the different objective lenses 22 through the objective lens conversion assembly 20, and superimposes the effects of the camera 31 and the different objective lenses 22 to meet different shooting requirements. This design can provide multiple optical properties in a single camera 31 system, so that the single camera 31 can adapt to multiple shooting scenes and achieve different camera effects, thereby increasing the multifunctionality. Compared with equipping an independent camera 31 for each shooting requirement, the present application helps to save costs.

[0056] Reference is made to Figure 1 , Figure 2 and Figure 9 As shown, the base 10 is a fixed part of the entire optical conversion device, and the base 10 comprises the imaging hole 11, which is used to correspond to the position of the camera 31, meaning that no matter which objective lens 22 is switched to the position corresponding to the imaging hole 11, light can enter the camera 31 through the objective lens 22 to achieve shooting.

[0057] In a possible implementation manner, the different objective lenses 22 include but are not limited to different thicknesses of the objective lenses 22, different shapes of end faces of the objective lenses 22, etc.

[0058] In a possible implementation manner, along the optical axis direction of the objective lens 22, the end face of the objective lens 22 can be a plane, a convex surface, a concave surface, etc., which can be flexibly selected according to the use requirement.

[0059] In a possible implementation manner, the number of the objective lenses 22 can be 2, 3 or 4, etc. The different objective lenses 22 can be, for example, at least two of a macro lens, a long-focus lens, an ultra-wide-angle lens, and a filter lens. The at least two different objective lenses 22 can provide different optical effects, such as wide angle, long focus, macro, etc., and this diversity enables the single camera 31 to adapt to multiple shooting scenes.

[0060] The movable frame 21 is movably arranged relative to the base 10, thereby realizing the switching of the different objective lenses 22.

[0061] In a possible implementation manner, the objective lens conversion assembly 20 rotates relative to the base 10; or the objective lens conversion assembly 20 slides relative to the base 10, both of which can realize the switching of the positions of the different objective lenses 22 corresponding to the imaging hole 11.

[0062] In a possible implementation manner, reference is made to Figure 2 andFigure 3 As shown, the objective lens conversion assembly 20 further comprises a protective cover 23, which is arranged on the side of the movable frame 21 away from the base 10, and the objective lens 22 is arranged between the movable frame 21 and the protective cover 23. The movable frame 21 is provided with at least two hollow holes 2111, and the objective lens 22 corresponds to the hollow holes 2111. The protective cover 23 comprises a first light-transmitting part 231 corresponding to the position of the hollow holes 2111.

[0063] In a possible implementation, the movable frame 21 comprises a mounting cavity 211, and the hollow holes 2111 are located on the bottom wall surface of the mounting cavity 211. The protective cover 23 is located in the mounting cavity 211, and the objective lens 22 is located between the bottom wall surface of the mounting cavity 211 and the protective cover 23, and the objective lens 22 covers the hollow holes 2111. The protective cover 23 blocks the objective lens 22 and prevents the objective lens 22 from falling off.

[0064] The protective cover 23 provides protection for the objective lens 22, protects the objective lens 22 from dust, dirt and other environmental factors, ensures that the objective lens 22 remains clean when not in use, and thus improves image quality and the durability of the optical conversion device.

[0065] In a possible implementation, as shown in Figure 1 , Figure 2 and Figure 3 The protective cover 23 can be a transparent cover plate, such as a transparent glass cover plate or a transparent plastic cover plate. The first light-transmitting part 231 on the protective cover 23 corresponds to the position of the objective lens 22, allowing light to pass through the first light-transmitting part 231 on the protective cover 23 and enter the objective lens 22. The first light-transmitting part 231 can be glass or transparent resin, and the material and design of the first light-transmitting part 231 need to ensure that light can pass through effectively without affecting the clarity and color of the captured image.

[0066] In a possible implementation, the hollow holes 2111 in the movable frame 21 are used to fix the objective lens 22, and the number of hollow holes 2111 corresponds to the number of objective lenses 22, so that the objective lenses 22 are fixed one-to-one in the hollow holes 2111. The precise manufacture of the hollow holes 2111 is crucial to ensure the optical alignment of the objective lenses 22.

[0067] Optionally, the hollow holes 2111 can be circular holes, and the objective lenses 22 can cover the hollow holes 2111.

[0068] In a possible implementation, the inner wall of the hollow hole 2111 comprises a groove, and the objective lens 22 can be fixed on the groove of the hollow hole 2111 through the second connecting member 25; or the objective lens 22 can be fixed at an end of the hollow hole 2111 away from the base 10 through the second connecting member 25. The protective cover 23 is arranged on the side of the movable frame 21 away from the base 10, and can prevent the objective lens 22 from being pulled out of the hollow hole 2111.

[0069] In a possible implementation, the second connecting member 25 can be a strip of glue, double-sided tape or glue, and is connected between the edge of the objective lens 22 and the edge of the hollow hole 2111, so as to ensure that the objective lens 22 can be firmly installed and remain stable during switching.

[0070] In a possible implementation, the objective lens switching assembly 20 further comprises a decorative member 24 arranged between the movable frame 21 and the protective cover 23, and the decorative member 24 comprises a second light-transmitting part 241 corresponding to the position of the objective lens 22. This ensures that light can enter the objective lens 22 through the second light-transmitting part 241.

[0071] In a possible implementation, the decorative member 24 is arranged between the movable frame 21 and the protective cover 23, and the decorative member 24 can be connected between the movable frame 21 and the protective cover 23 through a third connecting member 26. The third connecting member 26 can be a piece of adhesive tape, and the third connecting member 26 comprises a relief hole 261 corresponding to the position of the objective lens 22.

[0072] In a possible implementation, the decorative member 24 can be a film, and one side of the decorative member 24 facing the protective cover 23 can be provided with decorative patterns or decorative colors to improve the appearance.

[0073] In a possible implementation, the second light-transmitting part 241 can be a light-transmitting hole, or a transparent region through which light can pass.

[0074] In a possible implementation, as shown in Figure 1 , Figure 2 and Figure 3 , the base 10 comprises a main support 12 and a protective partition 13. The main support 12 comprises a receiving cavity 121, and the photographing hole 11 is located on the bottom wall of the receiving cavity 121. The protective partition 13 is arranged in the receiving cavity 121, and the protective partition 13 comprises a first light-transmitting part 131 corresponding to the position of the photographing hole 11.

[0075] The main support 12 can be circular, and the photographing hole 11 is a channel through which light enters the camera 31. The receiving cavity 121 is used to accommodate the protective partition 13 and the like, and the protective partition 13 provides additional protection and support to prevent internal reflection or other optical interference.

[0076] In a possible implementation, the protective partition 13 can be made of glass or resin, for example. The first light transmission part 131 is a transparent region through which light can pass without being blocked.

[0077] In a possible implementation, the base 10 further comprises a light shielding member 14 disposed between the main support 12 and the protective partition 13. The light shielding member 14 has a second light transmission part 141 corresponding to the position of the camera hole 11.

[0078] In a possible implementation, the light shielding member 14 can be a film. The light shielding member 14 can effectively shield light around the camera hole 11, thereby improving the shooting effect.

[0079] In a possible implementation, the light shielding member 14 can be disposed between the main support 12 and the protective partition 13 by the first connecting member 16. The first connecting member 16 can be glue or adhesive tape.

[0080] In a possible implementation, as shown in Figure 5 , Figure 6 and Figure 7 , the objective lens conversion assembly 20 is rotatably disposed in the accommodating cavity 121. The inner wall of the accommodating cavity 121 comprises at least two limiting grooves 122. The movable frame 21 comprises a rotating disc 213 and an elastic protrusion 212 disposed on the rotating disc 213. The elastic protrusion 212 extends to the edge of the rotating disc 213. When different objective lenses 22 correspond to the camera hole 11, the elastic protrusion 212 extends into different limiting grooves 122.

[0081] Optionally, the limiting grooves 122 are used to provide accurate positioning for the objective lens 22 during rotation of the objective lens conversion assembly 20, so as to ensure that each objective lens 22 can be accurately aligned with the camera hole 11 when in use, thereby ensuring transmission of the optical path.

[0082] Optionally, the elastic protrusion 212 is disposed at the edge of the rotating disc 213 and can extend into the limiting groove 122 when the rotating disc 213 rotates, thereby providing mechanical feedback and positioning. When each objective lens 22 is rotated into position, it can be accurately positioned.

[0083] In this application, when the objective lens conversion assembly 20 rotates relative to the base 10, the elastic protrusion 212 extends into different limiting grooves 122, so that the user can perceive that the objective lens 22 corresponds to the camera hole 11, thereby improving the accuracy of alignment of the objective lens 22 and the camera hole 11. Optionally, the elastic protrusion 212 elastically abuts against the inner wall of the accommodating cavity 121, which can prevent excessive vibration damage to the objective lens 22 when falling.

[0084] In a possible implementation, as shown inFigure 5 、 Figure 6 and Figure 7 As shown in

[0085] In a possible implementation, the shape of the teeth 2123 is consistent with the shape of the limiting groove 122.

[0086] Optionally, the elastic member 2122 is configured to elastically push the tooth-shaped member 2121, so that the teeth 2123 of the tooth-shaped member 2121 move in a direction away from the edge of the opening groove 2131. When the teeth 2123 of the tooth-shaped member 2121 are pressed by the inner side wall of the accommodating cavity 121, the tooth-shaped member 2121 can be pressed to make the elastic member 2122 elastically retract the teeth 2123 into the opening groove 2131, so as to avoid rigid collision between the teeth 2123 and the inner side wall of the accommodating cavity 121, and thus prevent damage.

[0087] In a possible implementation, the opening groove 2131 can be located on one side of the rotating disc 213, and the opening of the opening groove 2131 is located at the edge of the rotating disc 213.

[0088] In a possible implementation, the tooth-shaped member 2121 can be a tab, the teeth 2123 are triangular structures formed by bending the tab, and the elastic member 2122 can be a compression spring or a coil spring. The elastic member 2122 is deformed to press the tooth-shaped member 2121, so that the teeth 2123 of the tooth-shaped member 2121 extend out of the opening groove 2131 and abut against the inner side wall of the accommodating cavity 121.

[0089] In a possible implementation, the tooth-shaped member 2121 can be a tab, the elastic member 2122 can be a compression spring. The elastic member 2122 is deformed to press the tooth-shaped member 2121, so that the tooth-shaped member 2121 slides in the opening groove 2131, and the teeth 2123 of the tooth-shaped member 2121 extend out of the opening groove 2131 and abut against the inner side wall of the accommodating cavity 121.

[0090] In a possible implementation, referring to Figure 5 and Figure 6 As shown in

[0091] Such a structure, in the process of rotating the objective lens conversion assembly 20 relative to the base 10, the teeth 2123 of the toothed part 2121 move along at least two tooth grooves 124 and are driven by the shape of the tooth grooves 124, producing a clicking sound, producing a series of slight resistance and release, which provides a clear jerk for the user. Such feedback not only enhances the tactile experience of operation and increases the interest of rotating the objective lens conversion assembly 20, but also helps the user to better control the rotation process.

[0092] In a possible implementation, the depth of the tooth groove 124 is less than the depth of the limiting groove 122. Such a structure requires a smaller rotating torque when the teeth 2123 leave the tooth groove 124, and a larger rotating torque when the teeth 2123 leave the limiting groove 122. Therefore, the user can clearly feel that each objective lens 22 is rotated in place by the change of torque, and the accuracy of aligning the objective lens 22 with the imaging hole 11 is improved.

[0093] In a possible implementation, the movable frame 21 further comprises at least two fixed teeth arranged on the outer wall surface of the rotating disc 213. The length of the fixed teeth protruding from the outer wall surface of the rotating disc 213 is less than the length of the elastic protrusion 212 protruding from the outer wall surface of the rotating disc 213. The fixed teeth avoid affecting the positioning and fitting effect of the elastic protrusion 212 and the limiting groove 122.

[0094] In a possible implementation, the at least two fixed teeth arranged on the outer wall surface of the rotating disc 213 and the at least two tooth grooves 124 arranged on the inner wall of the accommodating cavity 121 form a gear meshing fitting mode, which is beneficial to improve the smoothness of the rotation of the objective lens conversion assembly 20.

[0095] In a possible implementation, referring to Figure 2 and Figure 3 The center position of the accommodating cavity 121 comprises a first rotating part 123, and the center position of the movable frame 21 comprises a second rotating part 214. One of the first rotating part 123 and the second rotating part 214 is a rotating shaft, and the other is a rotating hole. The rotating shaft is arranged in the rotating hole, and a bearing 15 is arranged between the rotating shaft and the rotating hole. The bearing 15 reduces mechanical wear and operation resistance, and can improve the smoothness of the rotation of the movable frame 21 relative to the main support 12.

[0096] In this example, the rotating shaft is inserted into the rotating hole to form a rotary connection, which ensures that the movable frame 21 can rotate smoothly around the rotating shaft to meet the performance requirements of the optical conversion device.

[0097] In a possible implementation, the second rotating part 214 at the center of the movable frame 21 is a rotating shaft, the inner ring of the bearing 15 is fixedly connected to the rotating shaft by the fastener 17, the first rotating part 123 at the center of the main support 12 is a rotating hole, and the outer ring of the bearing 15 extends into the rotating hole, so that the objective lens switching assembly 20 can rotate smoothly relative to the base 10.

[0098] In a possible implementation, the fastener 17 can be a screw, a bolt, a pin or the like.

[0099] In a possible implementation, as shown in Figure 2 and Figure 3 , the distance from the center of each hollow hole 2111 to the second rotating part 214 is consistent, that is, each hollow hole 2111 is on a circle with the second rotating part 214 as the center, so that when the movable frame 21 rotates relative to the base 10, it is ensured that each objective lens 22 can accurately correspond to the position of the imaging hole 11.

[0100] In a possible implementation, when the number of objective lenses 22 is four, the angle between adjacent two objective lenses 22 is 90° with the rotating center of the movable frame 21 as the center, and accordingly, the angle between adjacent two limiting grooves 122 is 90°, so that the objective lens 22 can be switched by rotating the objective lens switching assembly 20 by 90°.

[0101] In a possible implementation, when the number of objective lenses 22 is three, the angle between adjacent two objective lenses 22 is 120° with the rotating center of the movable frame 21 as the center, and accordingly, the angle between adjacent two limiting grooves 122 is 120°, so that the objective lens 22 can be switched by rotating the objective lens switching assembly 20 by 120°.

[0102] In other possible implementations, when the objective lens switching assembly 20 slides relative to the base 10, the movable frame 21 of the objective lens switching assembly 20 can be in a strip shape, and the at least two hollow holes 2111 can be arranged along a straight line, so that different objective lenses 22 can be switched by sliding the objective lens switching assembly 20 relative to the base 10. In order to better guide the sliding of the objective lens switching assembly 20, the objective lens switching assembly 20 and the base 10 can be matched by a sliding block and a track. For example, a track is arranged on the side of the base 10 facing the objective lens switching assembly 20, and a sliding block is arranged on the objective lens switching assembly 20 to slide along the track, so as to improve the smoothness of the sliding of the objective lens switching assembly 20.

[0103] The application also provides an intelligent terminal, which refers to Figure 8 and Figure 9As shown, the device includes a main body 30 and the aforementioned optical conversion device. The optical conversion device is disposed on the main body 30. The main body 30 includes a camera 31. The position of the camera aperture 11 of the optical conversion device corresponds to the position of the camera 31.

[0104] The aforementioned optical conversion device can be connected to the body 30 by means of gluing, welding, screwing, or vacuum adsorption. Optionally, the main support 12 is connected to the body 30 by means of gluing, welding, screwing, or vacuum adsorption, so that the base 10 remains relatively stationary relative to the body 30.

[0105] The main body 30 also includes an auxiliary light group 32, which may include at least one of a flash, a laser, and a projection light, and serves to improve the shooting effect of the camera 31.

[0106] This application provides an optical conversion device and a smart terminal, which realizes the switching of different objective lenses 22 through the objective lens conversion component 20. The clicking sound generated during the rotation of the objective lens conversion component 20, combined with the visual effect of the rotation of the objective lens conversion component 20, increases the user's interest in using it.

[0107] The optical conversion device and smart terminal provided in this application embodiment achieve switching between different objective lenses 22 by rotating the objective lens conversion component 20 and superimposing the effect with the camera, which can reduce the number of cameras built into the smart terminal and save costs.
