Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a dual-camera module. Background Technology

[0002] With the development of science and technology, we have now entered the digital age, which has driven the rapid development of the camera module industry. Optical cameras are mainly used in electronic devices such as mobile phones and digital cameras to capture light emitted by external objects and perform optical imaging.

[0003] A dual-camera module typically consists of a first camera module, a second camera module, and a mounting frame. The first and second camera modules are sequentially mounted on the mounting frame, and each module has a ribbon cable for electrical connection to an external circuit board. In existing technology, because the first and second camera modules are arranged side-by-side, their ribbon cables are inconvenient to install, resulting in a large space requirement. This hinders the installation of dual-camera modules and makes them incompatible with devices that have limited internal installation space.

[0004] Therefore, there is an urgent need to propose a dual-camera module to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a dual-camera module, which avoids the problems of inconvenient installation and large space occupation of dual-camera module wiring, and can thus be compatible with more devices with small internal installation space.

[0006] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0007] This utility model provides a dual-camera module, including:

[0008] The mounting bracket assembly has a first mounting space and a second mounting space sequentially provided;

[0009] A first camera module is installed within the first installation space, with its bottom protruding downwards from the first installation space and having a first ribbon cable; and

[0010] The second camera module is installed in the second installation space and has a second ribbon cable at the bottom;

[0011] The mounting bracket assembly has a cable channel on the side away from the first mounting space. The cable channel extends upward from the bottom of the mounting bracket assembly and connects to the second mounting space. The second ribbon cable passes through the cable channel and is electrically connected to an external circuit board. The first ribbon cable extends from the bottom side of the first camera module near the second camera module along the extension direction of the second ribbon cable, so that the first ribbon cable overlaps the bottom of the second ribbon cable.

[0012] In some implementations, the height of the cable tray is greater than the height when the first and second cables overlap.

[0013] In this implementation, the first and second cabling can overlap and be parallel to the bottom of the mounting bracket assembly, meaning the cable tray can accommodate the first and second cabling.

[0014] In some implementations, the mounting bracket assembly extends to the side opposite to the second mounting space with a limiting portion for limiting the mounting depth of the first camera module.

[0015] In some implementations, the first camera module includes a lens assembly and a CMOS assembly, the CMOS assembly protruding from the first mounting space.

[0016] In this implementation, since the first camera module and the second camera module need to be installed sequentially in the first mounting space and the second mounting space of the mounting bracket assembly by dispensing adhesive, and the CMOS component protrudes from the first mounting space, the problem of adhesive damaging the CMOS component can be avoided.

[0017] In some implementations, the limiting portion protrudes from the bottom of the first camera module, and the depth of the limiting portion protruding from the bottom of the first camera module is greater than the depth of the CMOS component protruding from the first mounting space.

[0018] In some implementations, the mounting bracket assembly includes a first frame and a second frame connected to the first frame, the first mounting space is formed on the first frame, the second mounting space is formed on the second frame, and the first frame and the second frame are not on the same horizontal plane.

[0019] In some implementations, the side of the first frame facing away from the first cable has a calibration slot for calibrating the installation depth of the first camera module.

[0020] In some implementations, a first guide mechanism is provided between the first camera module and the first frame; and / or

[0021] A second guide mechanism is provided between the second camera module and the second frame.

[0022] In this implementation, the first guiding mechanism makes it easier for the adhesive to enter the gap between the first camera module and the first frame, and the second guiding mechanism makes it easier for the adhesive to enter the gap between the second camera module and the second frame, thereby ensuring the bonding reliability between the two.

[0023] In some implementations, the first guiding mechanism includes a first guide groove formed on the upper surface of the first frame and communicating with the first mounting space, and a first groove formed on the periphery of the first camera module to guide and cooperate with the first guide groove; and / or

[0024] The second guiding mechanism includes a second guide groove formed on the upper surface of the second frame and connected to the second installation space, and a second groove formed on the periphery of the second camera module to guide and cooperate with the second guide groove.

[0025] In some implementations, the periphery of the mounting bracket assembly is provided with multiple mounting posts.

[0026] In summary, this utility model has at least the following advantages:

[0027] The dual-camera module provided by this utility model has a cable channel opened on the side of the fixing frame assembly away from the first mounting space. The cable channel is opened from the bottom of the fixing frame assembly upward and connected to the second mounting space. When the second ribbon cable passes through the cable channel, the second ribbon cable is parallel to the bottom of the fixing frame assembly. Since the installation depth of the first camera module is greater than the installation depth of the second camera module, the installation position of the first ribbon cable protrudes from the installation position of the second ribbon cable. As a result, when the first ribbon cable extends along the extension direction of the second ribbon cable, it can overlap the bottom of the second ribbon cable. This avoids the problem of the ribbon cable of the dual-camera module being inconvenient to install and occupying a lot of space. In this way, it can be compatible with more devices with smaller internal installation space. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see the appendix Figure 1 The dual-camera module of this utility model includes a mounting bracket assembly 1, a first camera module 2, and a second camera module 3.

[0040] Please see below. Figure 1 , Figure 1The diagram illustrates the structural relationship between the mounting bracket assembly 1, the first camera module 2, and the second camera module 3 in this embodiment of the present invention. Specifically, the mounting bracket assembly 1 has a first mounting space 11 and a second mounting space 12 sequentially. The first camera module 2 is installed in the first mounting space 11, with its bottom protruding downwards from the first mounting space 11 and having a first ribbon cable 21. The second camera module 3 is installed in the second mounting space 12 and has a second ribbon cable 31 at its bottom. A cable channel 13 is provided on the side of the mounting bracket assembly 1 facing away from the first mounting space 11. The cable channel 13 extends upwards from the bottom of the mounting bracket assembly 1 and connects to the second mounting space 12. The second ribbon cable 31 passes through the cable channel 13 and is electrically connected to an external circuit board. The first ribbon cable 21 extends from the bottom side of the first camera module 2 near the second camera module 3 along the extension direction of the second ribbon cable 31, so that the first ribbon cable 21 overlaps below the second ribbon cable 31.

[0041] In this embodiment, the first camera module 2 and the second camera module 3 are sequentially arranged in the first mounting space 11 and the second mounting space 12 opened in the fixing frame assembly 1. The first ribbon cable 21 and the second ribbon cable 31 are connected to the bottom of the first camera module 2 and the second camera module 3 in a one-to-one correspondence. By opening a wire passage groove 13 on the side of the fixing frame assembly 1 away from the first mounting space 11, and the wire passage groove 13 is opened from the bottom of the fixing frame assembly 1 upward and connected to the second mounting space 12, when the second ribbon cable 31 passes through the wire passage groove 13, the second ribbon cable 31 is parallel to the bottom of the fixing frame assembly 1, avoiding the bottom of the fixing frame assembly 1 pressing on the second ribbon cable 31, affecting the electrical connection between the second ribbon cable 31 and the external circuit board, and causing poor conductivity. Furthermore, the first camera module 2 protrudes from the first mounting space 11, so that the bottoms of the first camera module 2 and the second camera module 3 are not on the same horizontal plane. As a result, the depth of the first ribbon cable 21 installed in the first mounting space 11 is greater than the depth of the second ribbon cable 31 installed in the second mounting space 12. Thus, when the first ribbon cable 21 extends along the routing direction of the second ribbon cable 31, the first ribbon cable 21 can overlap the bottom of the second ribbon cable 31, avoiding the problem that the ribbon cables of the dual camera modules are inconvenient to install and occupy a lot of space.

[0042] The aforementioned dual-camera module, by opening a cable channel 13 on the side of the mounting bracket 1 away from the first mounting space 11, and the cable channel 13 opening upward from the bottom of the mounting bracket 1 and communicating with the second mounting space 12, allows the second ribbon cable 31 to pass through the cable channel 13, with the second ribbon cable 31 parallel to the bottom of the mounting bracket 1. Since the installation depth of the first camera module 2 is greater than the installation depth of the second camera module 3, the installation position of the first ribbon cable 21 protrudes from the installation position of the second ribbon cable 31. As a result, when the first ribbon cable 21 extends along the extension direction of the second ribbon cable 31, it can overlap the bottom of the second ribbon cable 31, avoiding the problem of the dual-camera module's ribbon cable being inconvenient to install and occupying a lot of space. This allows it to be compatible with more devices with smaller internal installation space.

[0043] In some preferred embodiments, the height of the cable guide 13 is greater than the height of the first ribbon cable 21 and the second ribbon cable 31 when they overlap. This allows the first ribbon cable 21 and the second ribbon cable 31 to overlap parallel to the bottom of the mounting bracket assembly 1, meaning the cable guide 13 can accommodate the first ribbon cable 21 and the second ribbon cable 31. This avoids the mounting bracket assembly 1 squeezing the first ribbon cable 21 and / or the second ribbon cable 31 during the installation of the dual-camera module, which could lead to poor conductivity when the first ribbon cable 21 and / or the second ribbon cable 31 are electrically connected to the external circuit board. It also improves the overall structural compactness.

[0044] Example 2:

[0045] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the dual-camera module of this utility model. Please refer to the appendix. Figure 2 ~Appendix Figure 3 .

[0046] Please see below. Figure 2 , Figure 2 The diagram illustrates the structural relationship between the limiting part 14 and the first camera module 2 in this embodiment of the invention. Specifically, the fixing bracket assembly 1 has a limiting part 14 extending from the side opposite to the second mounting space 12 to limit the mounting depth of the first camera module 2.

[0047] In this embodiment, the depth of the first camera module 2 installed in the first installation space 11 is determined by the limiting part 14, which avoids the problem that the first ribbon cable 21 at the bottom of the first camera module 2 cannot overlap with the second ribbon cable 31 at the bottom of the second camera module 3 due to inaccurate installation depth. At the same time, it avoids the problem that the first camera module 2 protrudes too much from the first installation space 11, resulting in the incompatibility between the dual camera module and external devices.

[0048] In some preferred embodiments, the first camera module 2 includes a lens assembly 22 and a CMOS component 23, with the CMOS component 23 protruding from the first mounting space 11. The lens assembly 22 focuses light onto the CMOS component 23 through a lens, ensuring that the light is accurately recorded on the CMOS component 23. The CMOS component 23 converts the incoming light into electrical signals to record image information. Since the first camera module 2 and the second camera module 3 need to be sequentially mounted in the first mounting space 11 and the second mounting space 12 of the mounting bracket assembly 1 by dispensing adhesive, the CMOS component 23 protruding from the first mounting space 11 avoids the problem of adhesive damaging the CMOS component 23.

[0049] In some preferred embodiments, the limiting portion 14 protrudes from the bottom of the first camera module 2, and the depth of the limiting portion 14 protruding from the bottom of the first camera module 2 is greater than the depth of the CMOS component 23 protruding from the first mounting space 11. This allows the limiting portion 14 to determine the mounting depth of the first camera module 2 when it is installed in the first mounting space 11, thereby ensuring that the first ribbon cable 21 can overlap below the second ribbon cable 31, thus guaranteeing the overall structural reliability.

[0050] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the first frame 15 and the second frame 16 in this embodiment of the invention. Specifically, the mounting bracket assembly 1 includes a first frame 15 and a second frame 16 connected to the first frame 15. A first mounting space 11 is formed on the first frame 15, and a second mounting space 12 is formed on the second frame 16. The first frame 15 and the second frame 16 are not on the same horizontal plane. This further ensures that the first camera module 2 and the second camera module 3 are not on the same horizontal plane, thus improving the reliability of the first ribbon cable 21 overlapping below the second ribbon cable 31. The second frame 16 can be connected to the first frame 15 by welding, embedding, or snap-fitting. Preferably, the second frame 16 is integrally formed into the first frame 15 to improve structural compactness.

[0051] In some more preferred embodiments, a calibration slot 151 for calibrating the installation depth of the first camera module 2 is provided on the side of the first frame 15 facing away from the first cable 21. The calibration slot 151 is located on the upper surface of the first frame 15, allowing the operator to determine the installation depth of the first camera module 2 within the first installation space 11, so that the upper surface of the first camera module 2 is parallel to the upper surface of the first frame 15. This improves assembly convenience while enhancing structural compactness.

[0052] Example 3:

[0053] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the dual-camera module of this utility model. Please refer to the appendix. Figure 4 , Figure 4 The specific structures of the first guide mechanism 17 and the second guide mechanism 18 in the embodiments of this utility model are illustrated.

[0054] A first guide mechanism 17 is provided between the first camera module 2 and the first frame 15; and / or a second guide mechanism 18 is provided between the second camera module 3 and the second frame 16.

[0055] In this embodiment, the first camera module 2 and the first frame 15, and the second camera module 3 and the second frame 16, need to be fixed together by an adhesive dispensing process. The first guide mechanism 17 makes it easier for the adhesive to enter the gap between the first camera module 2 and the first frame 15, and the second guide mechanism 18 makes it easier for the adhesive to enter the gap between the second camera module 3 and the second frame 16, thereby ensuring the reliability of the bonding between them. At the same time, the first guide mechanism 17 makes it easier for the first camera module 2 to be installed in the first mounting space 11 of the first frame 15, and the second guide mechanism 18 makes it easier for the second camera module 3 to be installed in the second mounting space 12 of the second frame 16.

[0056] In some preferred embodiments, the first guide mechanism 17 includes a first guide groove 171 formed on the upper end face of the first frame 15 and connected to the first mounting space 11, and a first groove 24 formed on the periphery of the first camera module 2 to cooperate with and guide the first guide groove 171; and / or the second guide mechanism 18 includes a second guide groove 181 formed on the upper end face of the second frame 16 and connected to the second mounting space 12, and a second groove 32 formed on the periphery of the second camera module 3 to cooperate with and guide the second guide groove 181.

[0057] In this embodiment, the adhesive enters the first groove 24, then the first guide groove 171, and flows along the first guide groove 171 into the first mounting space 11 to ensure that the first camera module 2 and the first frame 15 are bonded together. The first camera module 2 is square, and the first groove 24 is formed at the periphery of the four corners of the first camera module 2 to improve the bonding stability between each point and the first frame 15. The bonding method between the second camera module 3 and the second frame 16 is the same as that between the first camera module 2 and the first frame 15, and will not be described again here.

[0058] In some more preferred embodiments, the mounting bracket assembly 1 has a plurality of mounting posts 19 on its periphery. The mounting bracket assembly 1 is mounted to an external device via the plurality of mounting posts 19, thereby improving the connection stability between the dual camera module and the external device.

[0059] The dual-camera module of this utility model has a cable channel 13 on the side of the fixing frame assembly 1 away from the first mounting space 11. The cable channel 13 is opened from the bottom of the fixing frame assembly 1 and communicates with the second mounting space 12. When the second ribbon cable 31 passes through the cable channel 13, the second ribbon cable 31 is parallel to the bottom of the fixing frame assembly 1. Since the installation depth of the first camera module 2 is greater than the installation depth of the second camera module 3, the installation position of the first ribbon cable 21 protrudes from the installation position of the second ribbon cable 31. As a result, when the first ribbon cable 21 extends along the extension direction of the second ribbon cable 31, it can overlap the bottom of the second ribbon cable 31. This avoids the problem of the ribbon cable of the dual-camera module being inconvenient to install and occupying a lot of space. In this way, it can be compatible with more devices with smaller internal installation space.

[0060] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0062] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
