Technical Field

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

[0002] Camera modules are an essential component of mobile electronic devices. As camera module technology continues to develop, user demands for camera modules are becoming increasingly sophisticated. To improve control over the camera module, numerous circuits are added, complicating the wiring. Furthermore, adapting the structure of components within the camera module is necessary to facilitate wiring, potentially increasing the difficulty of component manufacturing. The wiring also requires multiple bends during routing, which can affect the stability of signal transmission. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a camera module that reduces the processing difficulty of the prism bracket, reduces the difficulty of wiring layout, and provides good signal transmission stability.

[0004] According to an embodiment of the present invention, the camera module includes: a photosensitive component, a driving component, and a prism component. The photosensitive component includes a chip and a chip circuit board. The driving component includes a lens and a driving part, the driving part being used to drive the lens to move, and a first electrical connector being provided on the outer side of the driving part. The prism component includes a prism bracket, a prism, a second electrical connector, and a circuit board assembly. The prism bracket has a receiving cavity, and the prism is disposed in the receiving cavity for guiding light incident on the lens toward the photosensitive component. The prism bracket has a first side and a second side facing away from each other. At least a portion of the photosensitive component and the driving component are disposed on the first side of the prism bracket, and the circuit board assembly is disposed on the second side of the prism bracket. The circuit board assembly is electrically connected to the first electrical connector and the chip circuit board, respectively, to realize the electrical connection between the driving part and the photosensitive component.

[0005] According to the camera module of this utility model embodiment, by setting a circuit board assembly, it is not necessary to process and arrange circuits on the prism bracket, which can reduce the processing difficulty of the prism bracket. In addition, it is beneficial to make the structure of the prism bracket more stable and less prone to deformation and other damage. Moreover, the circuits are arranged on the circuit board assembly, which can reduce the difficulty of circuit arrangement. The circuit board assembly can better transmit electrical signals between the photosensitive component and the driving unit, and the circuits arranged on the circuit board assembly are not easily deformed, which can improve the stability of electrical signal transmission between the photosensitive component and the driving unit.

[0006] In addition, the camera module according to this utility model may also have the following additional technical features:

[0007] In some embodiments of the present invention, the driving part has a protrusion extending toward the circuit board assembly, the first electrical connector is disposed on the protrusion, the protrusion abuts against the circuit board assembly to realize the electrical connection between the first electrical connector and the circuit board assembly, the protrusion has a notch, and the prism bracket is at least partially located in the notch.

[0008] In the above example, the prism bracket is located at least partially in the notch by abutting against the circuit board assembly through the protrusion. This not only helps to improve the compactness and stability of the camera module structure, but also shortens the distance between the drive unit and the circuit board assembly, optimizes the wiring layout, reduces the risk of faults such as short circuits and open circuits, and improves the reliability and service life of the camera module.

[0009] In some embodiments of this utility model, the driving unit is connected to the prism bracket and located on the first side of the prism bracket. The camera module further includes multiple third electrical connectors, which are lead terminals. Each third electrical connector passes through the prism bracket along the direction from the first side to the second side and has a third end and a fourth end protruding from the prism bracket. The third end is electrically connected to the first electrical connector, and the fourth end is electrically connected to the circuit board assembly. The prism bracket can define the extension direction of the third electrical connectors, thereby allowing for better layout of the circuitry constructed by the third electrical connectors. Furthermore, since the third electrical connectors pass through the prism bracket, the prism bracket can also provide better protection for the third electrical connectors.

[0010] In some embodiments of this invention, the camera module further includes a second electrical connector, which is at least partially located on the prism bracket. One end of the second electrical connector is connected to the chip circuit board, and the other end is connected to the circuit board assembly. Thus, the second electrical connector can effectively connect the chip circuit board and the circuit board assembly.

[0011] In some embodiments of this utility model, the second electrical connector is a flexible circuit board. The flexible circuit board includes a main body and a bent portion extending from the main body toward the circuit board assembly. The main body is electrically connected to the chip circuit board, and the bent portion is disposed on the prism bracket and electrically connected to the circuit board assembly. By connecting the photosensitive component and the circuit board assembly through the flexible circuit board, the complex spatial layout within the camera module can be better adapted, avoiding installation difficulties and space occupation problems caused by rigid connections. Furthermore, the signal transmission of the flexible circuit board is stable and reliable, which can effectively reduce signal attenuation and interference, thereby improving the imaging effect of the camera module.

[0012] In some embodiments of this utility model, the second electrical connector is a lead terminal. The second electrical connector passes through the prism bracket along the direction from the first side to the second side and has a first end and a second end protruding from the prism bracket. The first end is electrically connected to the chip circuit board, and the second end is electrically connected to the circuit board assembly. The prism bracket can limit the extension direction of the second electrical connector, thereby allowing for better layout of the circuit constructed by the second electrical connector. Furthermore, since the second electrical connector passes through the prism bracket, the prism bracket can also provide better protection for the second electrical connector.

[0013] In some embodiments of this utility model, multiple second electrical connectors are provided. At least one of the multiple second electrical connectors is configured as a first connector group, and at least one of the remaining components is configured as a second connector group. The first connector group and the second connector group are respectively arranged on both sides of the receiving cavity. This allows the multiple second electrical connectors to be arranged well, making reasonable use of the space of the prism support, and without interfering with the prism in the receiving cavity.

[0014] In some embodiments of this invention, the lead terminal is a metal sheet. The metal sheet has high strength and good toughness, can withstand certain external forces, enhances the stability of the connection between the lead terminal and the prism bracket, prevents loosening and detachment, and ensures high reliability. At the same time, the metal sheet is easy to process and shape, and can be customized to fit prism brackets of different specifications, facilitating installation and maintenance.

[0015] In some embodiments of this utility model, the circuit board assembly is glued to the prism bracket. This connection method is simple and convenient, and in terms of space utilization, compared to screw-in or snap-fit ​​connections, glued connections do not require additional installation space, allowing for a more compact camera module structure. Furthermore, it effectively prevents dust and moisture from entering the camera module through the connection point, thus avoiding short circuits and extending the lifespan of the camera module.

[0016] In some embodiments of this utility model, the circuit board assembly includes a circuit board and a reinforcing plate. The circuit board has wiring, and the reinforcing plate is disposed on the side of the circuit board away from the prism support. Therefore, the reinforcing plate can effectively improve the structural strength of the circuit board, making it less prone to bending and deformation. Furthermore, since the circuit board assembly is arranged on the second side of the prism support and includes the reinforcing plate, it can also effectively support the prism support, thereby significantly improving the structural strength of the prism support.

[0017] In some embodiments of this invention, the circuit board assembly is a metal plate. Metal plates have good heat dissipation performance, which is beneficial for the heat dissipation of the circuit board assembly. Furthermore, metal plates have relatively high structural strength and are not easily bent or deformed, thus making the lines arranged on the circuit board assembly less prone to bending and deformation, thereby improving the stability of the camera module's signal transmission.

[0018] This invention also proposes an electronic device having the camera module described in the above embodiments.

[0019] According to the embodiments of the present invention, the electronic device is equipped with the camera module described above, which allows the electronic device to take pictures effectively.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] The following is for reference. Figures 1-8 A camera module 100 according to an embodiment of the present utility model is described.

[0037] like Figures 1-2 As shown, the camera module 100 according to an embodiment of the present invention includes a photosensitive component 1, a driving component 2, and a prism component 3. The photosensitive component 1 includes a chip and a chip circuit board 11. The driving component 2 includes a lens 21 and a driving part 22. The driving part 22 is used to drive the lens 21 to move, so as to adjust the focal length of the camera module 100. This allows objects at different distances to be clearly focused on the photosensitive component 1, ensuring that the captured photos or videos are clear, thereby meeting various shooting needs.

[0038] Furthermore, a first electrical connector 23 is provided on the outer side of the drive unit 22. The prism assembly 3 includes a prism bracket 31, a prism 32, a second electrical connector 24, and a circuit board assembly 33. The prism bracket 31 is provided with a receiving cavity 311. The prism 32 is disposed in the receiving cavity 311 and is used to guide the light incident on the lens 21 toward the photosensitive component 1. The prism bracket 31 has a first side 312 and a second side 313 facing away from each other. At least a portion of the photosensitive component 1 and the drive assembly 2 are disposed on the first side 312 of the prism bracket 31. The circuit board assembly 33 is disposed on the second side 313 of the prism bracket 31. The circuit board assembly 33 is electrically connected to the first electrical connector 23 and the chip circuit board 11 respectively to realize the electrical connection between the drive unit 22 and the photosensitive component 1.

[0039] For example, the photosensitive component 1 is located entirely on the first side 312 of the prism holder 31.

[0040] For example, a portion of the photosensitive component 1 is located on the first side 312 of the prism holder 31.

[0041] For example, the drive component 2 is located entirely on the first side 312 of the prism bracket 31.

[0042] For example, a portion of the drive component 2 is located on the first side 312 of the prism bracket 31.

[0043] In the above example, when external light enters the prism 32 along the driving component 2, the prism 32 can reflect the light to the circuit board assembly 33. Furthermore, by arranging at least a portion of the photosensitive component 1 and the driving component 2 on the same side of the prism bracket 31, the compactness of the camera module 100 can be improved, which is beneficial to the miniaturization design of the camera module 100. In addition, the circuit board assembly 33 and the prism bracket 31 are designed separately, so there is no need for wiring processing and arrangement on the prism bracket 31. For example, there is no need to etch lines on the prism bracket 31. On the one hand, it can reduce the processing difficulty of the prism bracket 31 and reduce the cost of the prism bracket 31. On the other hand, it is understandable that if lines are etched on the prism bracket 31, the etched area of ​​the prism bracket 31 is likely to become a weak area of ​​the prism bracket 31, and the prism bracket 31 is prone to deformation and other damage in the weak area. However, in this application, there is no need to arrange lines on the prism bracket 31, so that the prism bracket 31 has no weak area, thereby making the structure of the prism bracket 31 more stable and less prone to deformation and other damage.

[0044] Furthermore, the circuitry is arranged on the circuit board assembly 33, which reduces the difficulty of circuitry arrangement. The circuit board assembly 33 can better transmit electrical signals between the photosensitive component 1 and the driving unit 22, and the circuitry arranged on the circuit board assembly 33 is not easily deformed, which can improve the stability of electrical signal transmission between the photosensitive component 1 and the driving unit 22.

[0045] Therefore, according to the camera module 100 of this utility model embodiment, by setting the circuit board assembly 33, it is not necessary to process and arrange the circuit on the prism bracket 31, which can reduce the processing difficulty of the prism bracket 31. In addition, it is beneficial to make the structure of the prism bracket 31 more stable and less prone to deformation or damage. Moreover, the circuit is arranged on the circuit board assembly 33, which can reduce the difficulty of circuit arrangement. The circuit board assembly 33 can better transmit the electrical signal between the photosensitive component 1 and the driving unit 22, and the circuit is not easily deformed when arranged on the circuit board assembly 33, which can improve the stability of the electrical signal transmission between the photosensitive component 1 and the driving unit 22.

[0046] In some embodiments of the present invention, the drive unit 22 has a protrusion 221 extending toward the circuit board assembly 33, a first electrical connector 23 is disposed on the protrusion 221, the protrusion 221 abuts against the circuit board assembly 33 to realize the electrical connection between the first electrical connector 23 and the circuit board assembly 33, the protrusion 221 is provided with a notch 222, and the prism bracket 31 is at least partially located in the notch 222.

[0047] like Figures 1-3 An example is shown, and as... Figure 7 and Figure 8 In another example shown, the drive assembly 2 further includes a drive portion 22 and a first electrical connector 23. A portion of the drive portion 22 surrounds the outer periphery of the prism bracket 31 and extends toward the circuit board assembly 33. A portion of the circuit board assembly 33 is opposite to the prism bracket 31, and another portion is opposite to the protrusion 221. The first electrical connector 23 is disposed on the protrusion 221 for electrically connecting the circuit board assembly 33 and the drive portion 22.

[0048] like Figures 1-3 An example is shown, and as... Figure 7 and Figure 8 In another example shown, the driving part 22 partially surrounds the outer periphery of the prism bracket 31 and extends towards the circuit board assembly 33. This can improve the structural compactness and stability of the camera module 100, and also shorten the distance between the driving part 22 and the circuit board assembly 33. Thus, when the first electrical connector 23 is installed on the driving part 22, the first electrical connector 23 can be better connected to the circuit board assembly 33, and the wiring layout can be optimized, reducing the risk of short circuits, open circuits and other faults, and improving the reliability and service life of the camera module 100.

[0049] In the above example, by setting the protrusion 221 and setting the first electrical connector 23 on the protrusion 221, it is not only beneficial to improve the structural compactness and stability of the camera module 100, but also to shorten the distance between the drive unit 22 and the circuit board assembly 33, optimize the wiring layout, reduce the risk of faults such as short circuits and open circuits, and improve the reliability and service life of the camera module 100.

[0050] In some embodiments of this utility model, such as Figures 4-6 As shown, the drive unit 22 is connected to the prism bracket 31 and located on the first side of the prism bracket 31. The camera module 100 also includes a plurality of third electrical connectors 34. The third electrical connectors 34 are lead terminals. The third electrical connectors 34 are inserted into the prism bracket 31 along the direction from the first side 312 to the second side 313 and have a third end and a fourth end protruding from the prism bracket 31. The third end is electrically connected to the first electrical connector 23 and the fourth end is electrically connected to the circuit board assembly 33.

[0051] In other words, the prism bracket 31 can limit the extension direction of the third electrical connector 34, thereby allowing for better layout of the circuit constructed by the third electrical connector 34. Furthermore, since the third electrical connector 34 is installed inside the prism bracket 31, the prism bracket 31 can also provide better protection for the third electrical connector 34.

[0052] Combination Figures 4-6 As shown, the prism bracket 31 separates the drive assembly 2 and the circuit board assembly 33. The drive assembly 2 generates electromagnetic signals during operation, and the circuitry on the circuit board assembly 33 also generates its own electromagnetic interference. The separation provided by the prism bracket 31 can, to a certain extent, provide electromagnetic shielding, reducing mutual interference between the two electromagnetic signals. This ensures more stable transmission of the image signal captured by the lens 21, avoiding problems such as increased image noise and decreased image quality caused by electromagnetic interference. Simultaneously, it ensures the normal operation of other functional modules on the circuit board assembly 33, improving the overall performance of the device. Furthermore, the wiring within the drive assembly 2 and the drive section 22 generate heat during operation. Similarly, the circuit board 331 also generates heat when powered on. Separating the drive assembly 2 and the circuit board assembly 33 by the prism bracket 31 not only facilitates heat dissipation for both the drive assembly 2 and the circuit board assembly 33 but also reduces mutual interference between them. Therefore, this contributes to the stable operation of the camera module 100.

[0053] For example, a through hole can be provided in the prism bracket 31, and the third electrical connector 34 can be assembled through the through hole, and then the two ends can be connected by welding.

[0054] For example, when the prism bracket 31 is injection molded, the third electrical connector 34 can be pre-embedded in the prism bracket 31, so that the third electrical connector 34 is embedded in the prism bracket 31. This makes the third electrical connector 34 more stable, reduces the risk of line damage caused by external impact, friction, etc., and ensures the stability of electrical connection.

[0055] For example, the third electrical connector 34 is inserted into the prism bracket 31 along the direction from the first side 312 to the second side 313. That is, the third electrical connector 34 extends along the thickness direction of the prism bracket 31. For example, the third electrical connector 34 is a metal wire. When the prism bracket 31 is injection molded, the third electrical connector 34 can be pre-embedded in the prism bracket 31, so that the third electrical connector 34 is embedded in the prism bracket 31. This extended arrangement of the third electrical connector 34 can improve the yield rate of the prism bracket 31 during injection molding. That is, the prism bracket 31 is easier to injection mold and less likely to produce defective products. Moreover, the third electrical connector 34 is not easy to bend when arranged in the prism bracket 31, and at the same time, it does not need to be bent, which can improve the signal transmission effect of the third electrical connector 34.

[0056] In some embodiments of this utility model, such as Figure 1-8 As shown in the figure, the camera module 100 also includes a second electrical connector 24, which is at least partially located on the prism bracket 31. One end of the second electrical connector 24 is connected to the chip circuit board 11, and the other end is connected to the circuit board assembly 33. Thus, the second electrical connector 24 can effectively connect the chip circuit board 11 and the circuit board assembly 33.

[0057] For example, the second electrical connector 24 may be located within the prism bracket 31;

[0058] For example, the second electrical connector 24 can be attached to the outer surface of the prism bracket 31.

[0059] like Figures 1-3 As shown, the second electrical connector 24 is arranged on the outer surface of the prism bracket 31. Thus, when the second electrical connector 24 electrically connects the photosensitive component 1 and the circuit board assembly 33, it can bypass the prism bracket 31. On the one hand, it can reduce signal interference and improve the accuracy of data transmission. On the other hand, it can reduce the structural design of the prism bracket 31. That is, there is no need to design and process a clearance hole inside the prism bracket 31 to allow the second electrical connector 24 to pass through. This simplifies the structure of the prism bracket 31 and helps to reduce the production difficulty and production cost of the prism bracket 31.

[0060] In some embodiments of this utility model, such as Figures 1-3 As shown, the second electrical connector 24 is a flexible circuit board assembly 33. The flexible circuit board includes a main body 241 and a bent portion 242 extending from the main body 241 toward the circuit board assembly 33. The main body 241 is electrically connected to the chip circuit board 11, and the bent portion 242 is disposed on the prism bracket 31 and electrically connected to the circuit board assembly 33.

[0061] In other words, the flexible circuit board assembly 33 is flexible and can be bent flexibly, making it well-suited to the complex spatial layout within the camera module 100. When passing over the prism bracket 31, it cleverly conforms to the contours of each component, avoiding installation difficulties and space occupation issues caused by rigid connections. At the same time, the flexible circuit board assembly 33 has good electrical performance and stable and reliable signal transmission, ensuring that the image signal captured by the photosensitive component 1 is quickly and accurately transmitted to the circuit board assembly 33, effectively guaranteeing image quality, reducing signal attenuation and interference, thereby improving the imaging effect of the camera module 100 and bringing users a better shooting experience.

[0062] In the above example, by connecting the photosensitive component 1 and the circuit board component 33 through the flexible circuit board component 33, the complex spatial layout within the camera module 100 can be better adapted, avoiding installation difficulties and space occupation problems caused by rigid connections. Furthermore, the signal transmission of the flexible circuit board component 33 is stable and reliable, which can effectively reduce signal attenuation and interference, thereby improving the imaging effect of the camera module 100.

[0063] In some embodiments of this utility model, such as Figures 4-8 As shown, the second electrical connector 24 is a lead terminal. The second electrical connector 24 passes through the prism bracket 31 along the direction from the first side 312 to the second side 313 and has a first end and a second end protruding from the prism bracket 31. The first end is electrically connected to the chip circuit board 11, and the second end is electrically connected to the circuit board assembly 33.

[0064] In other words, the prism bracket 31 can limit the extension direction of the second electrical connector 24, thereby allowing for better layout of the circuit constructed by the second electrical connector 24. Furthermore, since the second electrical connector 24 is installed inside the prism bracket 31, the prism bracket 31 can also provide better protection for the second electrical connector 24.

[0065] Combination Figures 4-6 An example is shown, and as... Figure 7 and Figure 8In another example shown, the prism bracket 31 separates the photosensitive component 1 and the circuit board assembly 33. The photosensitive component 1 generates electromagnetic signals during operation, and the circuitry on the circuit board assembly 33 also generates its own electromagnetic interference. The separation provided by the prism bracket 31 can, to a certain extent, act as electromagnetic shielding, reducing mutual interference between the two electromagnetic signals. This ensures more stable transmission of the image signal captured by the lens 21, avoiding problems such as increased image noise and decreased image quality caused by electromagnetic interference. Simultaneously, it ensures the normal operation of other functional modules on the circuit board assembly 33, improving the overall performance of the device. Furthermore, the circuitry and components within the photosensitive component 1 generate heat during operation, and similarly, the circuit board 331 also generates heat when powered on. Separating the photosensitive component 1 and the circuit board assembly 33 by the prism bracket 31 not only facilitates heat dissipation for both components but also reduces mutual interference between them, thereby contributing to the stable operation of the camera module 100.

[0066] For example, a through hole can be provided in the prism bracket 31, and the second electrical connector 24 can be assembled through the through hole and then connected at both ends by welding.

[0067] For example, when the prism bracket 31 is injection molded, the second electrical connector 24 can be pre-embedded in the prism bracket 31, so that the second electrical connector 24 is embedded in the prism bracket 31. This makes the second electrical connector 24 more stable, reduces the risk of line damage caused by external impact, friction, etc., and ensures the stability of electrical connection.

[0068] For example, the second electrical connector 24 is inserted into the prism bracket 31 along the direction from the first side 312 to the second side 313. That is, the second electrical connector 24 extends along the thickness direction of the prism bracket 31. For example, the second electrical connector 24 is a metal wire. When the prism bracket 31 is injection molded, the second electrical connector 24 can be pre-embedded in the prism bracket 31, so that the second electrical connector 24 is embedded in the prism bracket 31. This extended arrangement of the second electrical connector 24 can improve the yield rate of the prism bracket 31 during injection molding. That is, the prism bracket 31 is easier to injection mold and less likely to produce defective products. Moreover, the second electrical connector 24 is not easy to bend when arranged in the prism bracket 31, and at the same time, it does not need to be bent, which can improve the signal transmission effect of the second electrical connector 24.

[0069] In some embodiments of this utility model, multiple second electrical connectors 24 are provided. At least one of the multiple second electrical connectors 24 is configured as a first connector group 25, and at least one of the remaining ones is configured as a second connector group 26. The first connector group 25 and the second connector group 26 are respectively arranged on both sides of the receiving cavity 311. Thus, the multiple second electrical connectors 24 can be arranged well, making reasonable use of the space of the prism support 31, and without interfering with the prism 32 in the receiving cavity 311.

[0070] In some embodiments of this utility model, the lead terminal is a metal sheet. The metal sheet has high strength and good toughness, and can withstand a certain external force, enhancing the stability of the connection between the lead terminal and the prism bracket 31, preventing loosening and falling off, and ensuring high reliability. At the same time, the metal sheet is easy to process and form, and can be customized to fit different specifications of prism brackets 31, facilitating installation and maintenance.

[0071] In some embodiments of this utility model, the circuit board assembly 33 and the prism bracket 31 are glued together. The connection method is simple and convenient. In terms of space utilization, compared with screw connection, snap connection and other connection methods, glued connection does not require the reservation of additional installation space, which makes the structure of the camera module 100 more compact. In addition, it can better prevent dust, moisture and other substances from entering the camera module 100 through the connection, thereby avoiding short circuit and other faults, and can better extend the service life of the camera module 100.

[0072] In some embodiments of this utility model, such as Figures 1-8 As shown, the circuit board assembly 33 includes a circuit board 331 and a reinforcing plate 332. Circuitry is arranged on the circuit board 331, and the reinforcing plate 332 is located on the side of the circuit board 331 away from the prism support 31. Therefore, the reinforcing plate 332 can effectively improve the structural strength of the circuit board 331, making it less prone to bending and deformation. Furthermore, the circuit board assembly 33 is arranged on the second side 313 of the prism support 31, and including the reinforcing plate 332, it can also effectively support the prism support 31, thereby significantly improving the structural strength of the prism support 31.

[0073] In some embodiments of this utility model, the circuit board assembly 33 is a metal plate. The metal plate has good heat dissipation performance, which is beneficial to the heat dissipation of the circuit board assembly 33. In addition, the metal plate has relatively high structural strength and is not easy to bend or deform, so that the lines arranged on the circuit board assembly 33 are also not easy to bend or deform, thereby improving the stability of signal transmission of the camera module 100.

[0074] In some embodiments of this application, the connection between two adjacent conductive structures can be achieved directly through soldering, such as tin soldering.
