Description

Technical Field

[0001] This utility model relates to the field of camera module switching technology, and in particular to a device with a prism that can switch between different types of camera modules. Background Technology

[0002] In today's era of rapid digital information development, image acquisition, as a crucial means of information gathering, is widely used in numerous fields, from everyday mobile phone photography and video recording to professional fields such as security monitoring, industrial inspection, and medical imaging. The demands on camera technology are constantly increasing. With the diversification and refinement of market demands, a single camera module can no longer meet the diverse needs of different scenarios regarding image quality, shooting angle, focal length range, and other aspects. To achieve richer and higher-quality shooting functions, traditional mobile phone cameras are increasingly equipped with multiple camera modules, typically requiring as many holes as there are camera modules, severely impacting the phone's aesthetics. Utility Model Content

[0003] Based on this, it is necessary to address the aforementioned technical problems by providing a device with a prism that allows switching between different types of camera modules. This device involves installing a rotating component and a reflective lens in the center of the mounting slot on a mounting plate. Four camera modules are respectively mounted on the front and rear sides and the left and right sides of the reflective lens. A light-transmitting hole corresponding to each camera module is provided on the cover plate. In use, the reflective surface of the reflective lens is first aligned with the left-side camera module. Light then passes through the light-transmitting hole, the second mirror, the reflective mirror, and the first mirror to enter the left-side camera module for shooting. When the right-side camera module needs to be used, a motor is activated to rotate a worm gear. During rotation, the worm gear, in conjunction with a worm wheel, rotates the shaft, mounting base, and reflective lens to the right. Light then passes through the light-transmitting hole, the second mirror, the reflective mirror, and the first mirror to enter the right-side camera module for shooting. Through a clever mechanical structure and optical principles, the rotation of the reflective lens enables stable switching between different camera modules, automatically selecting different types of camera modules. This effectively solves the drawback of traditional multi-camera modules requiring multiple light-transmitting holes, improving the aesthetics of the mobile phone.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A device with a prism that can switch between different types of camera modules includes:

[0006] The system comprises a mounting plate, a cover plate, at least two camera modules, a reflective lens, and a rotating assembly. The mounting plate has a mounting groove, and the cover plate is fixedly connected to the mounting plate and has a light-transmitting hole. The camera modules and the reflective lens are both disposed inside the mounting groove. The reflective lens is used to position one of the camera modules and the light-transmitting hole on the same optical path. The rotating assembly is disposed inside the mounting groove and is used to rotate the reflective lens so that it is aligned with the camera module and the light-transmitting hole on the same optical path.

[0007] Furthermore, the reflecting lens is a prism.

[0008] Furthermore, the prism has a triangular cross-section and includes a first mirror surface, a second mirror surface, and a reflecting mirror surface. Light enters the camera module through the light-transmitting hole, the second mirror surface, the reflecting mirror surface, and the first mirror surface.

[0009] Furthermore, the number of camera modules is four, the rotating component and the reflective lens are installed in the middle of the mounting groove, and the four camera modules are respectively installed on the front and rear sides and the left and right sides of the reflective lens.

[0010] Furthermore, the mounting plate is the main body of the mobile phone, and the cover plate is the back cover of the mobile phone.

[0011] Furthermore, the angle between the first mirror and the second mirror is degrees, and the angle between the first mirror and the reflecting mirror is degrees.

[0012] Furthermore, the rotating assembly includes a motor, a rotating shaft, and a mounting base. The reflective lens is fixedly connected to the mounting base. One end of the rotating shaft is fixedly connected to the mounting base, and the other end of the rotating shaft is rotatably connected to the inner bottom wall of the mounting groove. The motor is fixedly connected to the inner bottom wall of the mounting groove, and the output end of the motor is used to drive the rotating shaft to rotate.

[0013] Furthermore, a worm is fixedly connected to the output end of the motor, and a worm wheel is fixedly connected to the outer surface of the rotating shaft, with the worm and the worm wheel meshing together.

[0014] Furthermore, the mounting base has a triangular cross-section, and a triangular groove corresponding to the reflective lens is formed on the outer side of the upper surface of the mounting base.

[0015] Furthermore, it also includes a transparent protective cover, which is fixedly connected to the inner bottom wall of the mounting groove, and the camera module, reflective lens and rotating assembly are all located inside the transparent protective cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model provides a device with a prism that can switch between different types of camera modules. By installing a rotating component and a reflective lens in the middle of the mounting slot of the mounting plate, four camera modules are respectively installed on the front and rear sides and the left and right sides of the reflective lens. The cover plate has light-transmitting holes corresponding to the camera modules. Through ingenious mechanical structure and optical principles, the rotation of the reflective lens is used to achieve stable switching between different camera modules and automatically select different types of camera modules. This effectively solves the drawback of traditional multi-camera modules requiring multiple light-transmitting holes and improves the aesthetics of the mobile phone.

[0018] The device with a prism that allows switching between different types of camera modules provided by this utility model first aligns the reflective surface of the reflective lens with the camera module on the left.

At this time, light enters the camera module on the right through the light-transmitting hole, the second mirror, the reflective mirror, and the first mirror for shooting. Thus, the rotation of the reflective lens is used to achieve the switching between different camera modules. Attached Figure Description

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As described in the background section, traditional mobile phones are increasingly equipped with camera modules, and the number of holes required for each camera module is roughly equal to the number of holes needed, which seriously affects the aesthetics of the phone.

[0029] To solve this technical problem, this utility model provides a device with a prism that can switch between different types of camera modules. A rotating component 7 and a reflective lens 6 are installed in the middle of the mounting groove 3 of the mounting plate 1. Four camera modules 5 are respectively installed on the front and rear sides and the left and right sides of the reflective lens 6. A light-transmitting hole 4 corresponding to each camera module 5 is provided on the cover plate 2. In use, the reflective surface 603 of the reflective lens 6 is first aligned with the left-side camera module 5. At this time, light passes through the light-transmitting hole 4, the second mirror surface 602, the reflective surface 603, and the first mirror surface 601 to enter the left-side camera module 5 for shooting. When it is necessary to use the right-side camera module 5 for shooting... When the motor 701 is activated, it drives the worm gear 704 to rotate. During the rotation, the worm gear 704, in conjunction with the worm wheel 705, drives the rotating shaft 702, the mounting base 703, and the reflective lens 6 to rotate to the right. At this time, light enters the camera module 5 on the right side through the light-transmitting hole 4, the second mirror 602, the reflective mirror 603, and the first mirror 601 for shooting. Thus, through a clever mechanical structure and optical principle, the rotation of the reflective lens 6 is used to achieve stable switching between different camera modules 5, automatically selecting different types of camera modules 5. This effectively solves the drawback of traditional multi-camera modules 5 requiring multiple light-transmitting holes 4, and improves the aesthetics of the mobile phone.

[0030] For details, please refer to Figure 1-6 The device with a prism that can switch between different types of camera modules specifically includes:

[0031] Mounting plate 1 and cover plate 2, mounting plate 1 has a mounting groove 3, cover plate 2 is fixedly connected to mounting plate 1, and cover plate 2 has a light-transmitting hole 4.

[0032] At least two camera modules 5 and a reflective lens 6 are provided. Both the camera modules 5 and the reflective lens 6 are disposed inside the mounting groove 3. The reflective lens 6 is used to ensure that one of the camera modules 5 and the light-transmitting hole 4 are located on the same optical path.

[0033] The rotating component 7 is located inside the mounting slot 3. The rotating component 7 is used to rotate the reflective lens 6 so that it is on the same optical path as the camera module 5 and the light-transmitting hole 4. The rotating component 7 can switch between different modules. Since they are all the same light-transmitting hole 4, there will be no change in visual difference, resulting in a better shooting experience for the camera module 5.

[0034] The device with a prism that allows switching between different types of camera modules provided by this utility model has a rotating component 7 and a reflective mirror 6 installed in the middle of the mounting groove 3 of the mounting plate 1. Four camera modules 5 are respectively installed on the front and rear sides and the left and right sides of the reflective mirror 6. The cover plate 2 has light-transmitting holes 4 corresponding to the camera modules 5. In use, the reflective mirror surface 603 of the reflective mirror 6 is first aligned with the left camera module 5. At this time, light passes through the light-transmitting hole 4, the second mirror surface 602, the reflective mirror surface 603, and the first mirror surface 601 to enter the left camera module 5 for shooting. When it is necessary to use the right camera module 5 for shooting, The starter motor 701 drives the worm gear 704 to rotate. During the rotation, the worm gear 704, in conjunction with the worm wheel 705, drives the rotating shaft 702, the mounting base 703, and the reflective mirror 6 to rotate to the right. At this time, light enters the camera module 5 on the right side through the light-transmitting hole 4, the second mirror 602, the reflective mirror 603, and the first mirror 601 for shooting. Thus, through a clever mechanical structure and optical principle, the rotation of the reflective mirror 6 is used to achieve stable switching between different camera modules 5, automatically selecting different types of camera modules 5, effectively solving the drawback of traditional multi-camera modules 5 requiring multiple light-transmitting holes 4.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0038] Example 1

[0039] Please refer to Figure 1-3 A device with a prism that can switch between different types of camera modules includes a mounting plate 1 and a cover plate 2. The mounting plate 1 has a mounting groove 3, the cover plate 2 is fixedly connected to the mounting plate 1, and the cover plate 2 has a light-transmitting hole 4.

[0040] At least two camera modules 5 and a reflective lens 6 are provided. Both the camera modules 5 and the reflective lens 6 are disposed inside the mounting groove 3. The reflective lens 6 is used to ensure that one of the camera modules 5 and the light-transmitting hole 4 are located on the same optical path.

[0041] Rotating component 7 is located inside the mounting slot 3. Rotating component 7 is used to rotate the reflective lens 6 so that it is on the same optical path as the camera module 5 and the light-transmitting hole 4.

[0042] The device with prisms that allows switching between different types of camera modules provided in this embodiment involves installing a rotating assembly 7 and a reflective mirror 6 in the middle of the mounting slot 3 of the mounting plate 1. Four camera modules 5 are respectively installed on the front and rear sides and the left and right sides of the reflective mirror 6. A light-transmitting hole 4 corresponding to each camera module 5 is provided on the cover plate 2. In use, the reflective mirror surface 603 of the reflective mirror 6 is first aligned with the left-side camera module 5. At this time, light passes through the light-transmitting hole 4, the second mirror surface 602, the reflective mirror surface 603, and the first mirror surface 601 into the left-side camera module 5 for shooting. When it is necessary to use the right-side camera module 5 for shooting, the motor is started. 701 drives the worm gear 704 to rotate. During the rotation, the worm gear 704, in conjunction with the worm wheel 705, drives the rotating shaft 702, mounting base 703, and reflective lens 6 to rotate to the right. At this time, light enters the camera module 5 on the right side through the light-transmitting hole 4, the second mirror 602, the reflective mirror 603, and the first mirror 601 for shooting. Thus, through a clever mechanical structure and optical principle, the rotation of the reflective lens 6 is used to achieve stable switching between different camera modules 5, automatically selecting different types of camera modules 5. This effectively solves the drawback of traditional multi-camera modules 5 requiring multiple light-transmitting holes 4, and improves the aesthetics of the mobile phone.

[0043] Example 2

[0044] The device with a prism that can switch between different types of camera modules provided in Embodiment 1 is further optimized, specifically, as follows: Figure 2 and Figure 3As shown, the reflecting lens 6 is a prism; the cross-section of the prism is a triangular structure, and the prism includes a first mirror surface 601, a second mirror surface 602, and a reflecting mirror surface 603. Light enters the camera module 5 through the light-transmitting hole 4, the second mirror surface 602, the reflecting mirror surface 603, and the first mirror surface 601. Thus, in use, the reflecting mirror surface 603 of the reflecting lens 6 is first aligned with the camera module 5 on the left. At this time, light enters the camera module 5 on the left through the light-transmitting hole 4, the second mirror surface 602, the reflecting mirror surface 603, and the first mirror surface 601 for shooting.

[0045] like Figure 1 As shown, there are four camera modules 5. The rotating component 7 and the reflective lens 6 are installed in the middle of the mounting slot 3. The four camera modules 5 are installed on the front and rear sides and the left and right sides of the reflective lens 6, respectively. The mounting plate 1 is the main body of the mobile phone, and the cover plate 2 is the back cover of the mobile phone. In this way, the rotating component 7 is electrically connected to the motherboard inside the main body of the mobile phone. The mobile phone screen controls the rotation of the rotating component 7. Multiple camera modules 5 can be installed on the main body of the mobile phone. At the same time, a light-transmitting hole 4 is opened on the back cover of the mobile phone. The mobile phone can not only use multiple camera modules 5 to take pictures, but also improve the aesthetics.

[0046] like Figure 3 As shown, the angle between the first mirror 601 and the second mirror 602 is 90 degrees, and the angle between the first mirror 601 and the reflecting mirror 603 is 45 degrees. In this way, light passes through the light-transmitting hole 4 and the second mirror 602 and enters the reflecting mirror 603. At this time, the reflecting mirror 603 completely reflects the light from the first mirror 601 to the camera module 5.

[0047] Example 3

[0048] The device with prism and switchable different types of camera modules provided in Embodiment 1 or 2 is further optimized, such as... Figure 4 , Figure 5 and Figure 6As shown, the rotating assembly 7 includes a motor 701, a rotating shaft 702, and a mounting base 703. The reflective mirror 6 is fixedly connected to the mounting base 703. One end of the rotating shaft 702 is fixedly connected to the mounting base 703, and the other end of the rotating shaft 702 is rotatably connected to the inner bottom wall of the mounting groove 3. The motor 701 is fixedly connected to the inner bottom wall of the mounting groove 3, and the output end of the motor 701 is used to drive the rotating shaft 702 to rotate. A worm gear 704 is fixedly connected to the output end of the motor 701, and a worm wheel 705 is fixedly connected to the outer surface of the rotating shaft 702. The worm gear 704 and the worm wheel 705 are meshed together. The motor 701 can precisely control the rotation angle. The positions of the multiple camera modules 5 are one-to-one. When different camera modules 5 need to be used for shooting, the motor 701 is started to drive the worm gear 704 to rotate. During the rotation, the worm gear 704 cooperates with the worm wheel 705 to drive the rotating shaft 702, the mounting base 703 and the reflective lens 6 to rotate to the right. At this time, light enters the camera module 5 on the right through the light-transmitting hole 4, the second mirror 602, the reflective mirror 603 and the first mirror 601 for shooting. Thus, through the ingenious mechanical structure and optical principle, the rotation of the reflective lens 6 is used to achieve stable switching between different camera modules 5 and automatically select different types of camera modules 5.

[0049] like Figure 5 and Figure 6 As shown, the mounting base 703 has a triangular cross-section. A triangular groove 706 corresponding to the reflective lens 6 is provided on the outer side of the upper surface of the mounting base 703. The reflective lens 6 is located inside the triangular groove 706. Limiting screws 707 are threaded to both the front and rear sides of the mounting base 703. The limiting screws 707 are used to fix the reflective lens 6. During installation, simply place the reflective lens 6 into the triangular groove 706 of the mounting base 703 and then tighten the limiting screws 707 to fix the reflective lens 6. The installation is very convenient.

[0050] Example 4

[0051] The device with prism that can switch between different types of camera modules provided in the above embodiments is further optimized, such as... Figure 2 and Figure 4 As shown, it also includes a transparent protective cover 8, which is fixedly connected to the inner bottom wall of the mounting groove 3.

This structural design can protect the camera module 5, the reflective lens 6, and the rotating assembly 7, prevent dust from entering, and improve their service life.

[0052] The device with a prism that can switch between different types of camera modules provided by this utility model is used as follows:

[0053] By installing the rotating assembly 7 and the reflective lens 6 in the middle of the mounting slot 3 of the mounting plate 1, four camera modules 5 are respectively installed on the front and rear sides and the left and right sides of the reflective lens 6. The cover plate 2 has light-transmitting holes 4 corresponding to the camera modules 5. In use, the reflective mirror surface 603 of the reflective lens 6 is first aligned with the left camera module 5. At this time, light enters the left camera module 5 through the light-transmitting hole 4, the second mirror surface 602, the reflective mirror surface 603, and the first mirror surface 601 for shooting. When it is necessary to use the right camera module 5 for shooting, the motor 701 is started to drive the worm gear 704 to rotate. During its rotation, the worm gear 704, in conjunction with the worm wheel 705, drives the rotating shaft 702, mounting base 703, and reflective lens 6 to rotate to the right. At this time, light enters the camera module 5 on the right side through the light-transmitting hole 4, the second mirror 602, the reflective mirror 603, and the first mirror 601 for shooting. Thus, through a clever mechanical structure and optical principle, the rotation of the reflective lens 6 enables stable switching between different camera modules 5, automatically selecting different types of camera modules 5. This effectively solves the drawback of traditional multi-camera modules 5 requiring multiple light-transmitting holes 4, improving the aesthetics of the phone.
