Description
Camera module and interactive smart tablet Technical Field
[0001] The embodiments of the present application relate to the technical field of display devices, and in particular to a camera module and an interactive smart tablet. Background Art
[0002] With the advancement and development of science and technology, the application scenarios of camera modules have become increasingly extensive. More and more electronic devices are equipped with camera modules, such as interactive smart tablets, large commercial display screens, touch-screen all-in-one computers, teaching and conference all-in-one computers, televisions and other electronic devices to realize their camera or monitoring functions.
[0003] Taking the interactive smart tablet as an example, the interactive smart tablet is equipped with a camera module to acquire information. When the camera module is working, it will generate a lot of heat. If the heat cannot be discharged in time, it will affect the stability of the camera module and thus affect the stability of the interactive smart tablet.
[0004] Summary of the Invention
[0005] The embodiments of the present application aim to provide a camera module and an interactive smart tablet to improve the heat dissipation effect of the camera module.
[0006] In order to solve the technical problems, the embodiments of the present application adopt the following technical solutions:
[0007] In the first aspect, the present application proposes a camera module, comprising an ISP board, a camera, a heat-conducting plate and a heat-conducting sheet. The ISP board is provided with a chip and a connection seat, and the connection seat is provided with a plug-in position. The camera is connected to an FFC cable, and the FFC cable has a plug-in portion, and the plug-in portion is plugged into the plug-in position and electrically connected to the ISP board. The heat-conducting cover plate is provided on the ISP board, and the plug-in position is provided facing the heat-conducting cover plate. The end face of the heat-conducting cover plate facing the ISP board is convexly provided with an elastic bracket, and the elastic bracket is supported between the heat-conducting cover plate and the plug-in portion. The heat-conducting sheet is provided on the heat-conducting cover plate and is attached between the heat-conducting cover plate and the chip.
[0008] In the above technical solution, by placing a thermally conductive sheet between the heat-conducting cover plate and the chip, the heat generated by the chip during operation can be transferred to the heat-conducting sheet through the thermally conductive sheet, and then conducted to the heat-conducting cover plate through the thermally conductive sheet, and finally dissipated from the heat-conducting cover plate to the outside world, which can improve the heat dissipation efficiency of the chip and thus ensure the stable operation of the camera module. At the same time, the heat-conducting cover plate has an elastic bracket for pressing the connector. The elastic bracket can apply elastic force to the connector and the plug-in portion of the FFC cable, so that the FFC cable and the connector are plugged in stably and connected, thereby ensuring stable operation of the camera.
[0009] In some preferred embodiments, a thermally conductive silicone layer is disposed between the thermally conductive sheet and the chip. This layer fills the gap between the thermally conductive sheet and the chip, further improving the efficiency of heat conduction between the thermally conductive sheet and the chip, thereby enhancing the chip's heat dissipation performance. Furthermore, the thermally conductive silicone grease layer acts as a cushion to prevent direct, rigid contact between the chip and the thermally conductive sheet, thereby reducing pressure damage to the chip.
[0010] In some preferred embodiments, the end surface of the thermally conductive cover plate facing the ISP board is provided with a plurality of first clips, which collectively enclose a first clipping space. The thermally conductive sheet is disposed in the first clipping space and clipped to the first clips to secure the thermally conductive sheet to the thermally conductive cover plate. Clipping the thermally conductive sheet facilitates installation and removal of the sheet and facilitates subsequent maintenance.
[0011] In some preferred embodiments, the camera module further includes a mounting bracket having a mounting platform with a plurality of second clips protruding from an upper portion of the mounting platform. The ISP board is mounted on the mounting platform and engages with the plurality of second clips to secure the ISP board to the mounting bracket. Engaging the ISP board with the mounting bracket facilitates not only installation but also subsequent disassembly and maintenance.
[0012] In some preferred embodiments, the mounting bracket has a mounting slot defined on its end surface facing away from the mounting platform, and the camera is secured to the mounting slot. Providing a mounting slot to accommodate the camera reduces the space occupied by the camera, thereby meeting the requirements of a compact camera module. Furthermore, the mounting slot at least partially accommodates the camera, thereby reducing the camera from being eroded by external elements such as rain, dew, and dust, thereby ensuring clear imaging.
[0013] In some preferred embodiments, the end surface of the thermally conductive cover plate facing the ISP board is provided with a plurality of convex reinforcing ribs. The ribs enhance the strength of the thermally conductive cover plate and reduce deformation. Some ribs can be arranged horizontally, while others can be arranged longitudinally. This staggered arrangement prevents bending and deformation of the thermally conductive cover plate in all directions.
[0014] In some preferred embodiments, the thermally conductive cover plate includes a base material portion and a thermally conductive material portion. The base material portion includes at least one of PPS, PA6, PA66, LCP, TPE, PC, PP, PPA, and PEEK. The thermally conductive material portion includes at least one of AlN, SiC, Al2O3, and graphite. The aforementioned non-metallic base material is stable and not easily corroded by external impurities such as rainwater and dust, thereby increasing the service life of the thermally conductive cover plate. Simultaneously, the addition of a portion of metal thermally conductive material with excellent thermal conductivity can improve the thermal conductivity of the thermally conductive cover plate. The combination of the base material portion and the thermally conductive material portion can provide the thermally conductive cover plate with better thermal conductivity and a longer service life.
[0015] In some preferred embodiments, the elastic bracket includes a first connector, a second connector, and a supporting member. The first connector is disposed opposite the second connector. The first connector includes a first section and a second section. The first section is connected to the end of the thermally conductive cover plate facing the ISP board and is bent toward the second connector. The second section is connected to the end of the first section facing away from the thermally conductive cover plate and is bent away from the second connector. The second connector includes a third section and a fourth section. The third section is connected to the thermally conductive cover plate and is bent toward the first connector. The fourth section is connected to the end of the third section facing away from the thermally conductive cover plate and is bent away from the first connector. The supporting member has one end connected to the end of the second section facing away from the first section and the other end connected to the end of the fourth section facing away from the third section. The supporting member is configured to abut against the plug-in portion plugged into the connector. The first section, the second section, the third section and the fourth section can enclose a buffer space. When the supporting member is subjected to force, the connection between the first section and the second section gradually approaches the connection between the third section and the fourth section, thereby forming a buffer space for the supporting member to crimp the connecting seat. This can reduce friction damage to the plug-in part and the connecting seat while crimping the plug-in part.
[0016] In some preferred embodiments, the elastic bracket and the heat-conducting cover plate are integrally formed, which can ensure the connection strength between the elastic bracket and the heat-conducting cover plate, thereby ensuring a stable connection and stabilizing the crimping plug-in portion.
[0017] In some preferred embodiments, the thermally conductive sheet completely covers the chip when viewed from the thermally conductive sheet to the chip. This allows for full contact between the chip and the thermally conductive sheet, increasing the contact area and thereby improving heat transfer efficiency. Furthermore, the complete coverage prevents interference with the chip by the first clip.
[0018] In a second aspect, the present application also proposes an interactive smart tablet, comprising a camera module as described in any embodiment of the first aspect above.
[0019] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are listed below.

The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.
[0044] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive with other embodiments. Furthermore, the technical features described below in the different embodiments of the present application may be combined with each other as long as they do not conflict with each other.
[0045] First, embodiments of the present application provide a camera module 100. Referring to Figures 1 and 2 , the camera module 100 includes an ISP board 10, a camera 20, a heat-conducting cover plate 30, and a heat-conducting sheet 40. The camera 20 is electrically connected to the ISP board 10, the heat-conducting cover plate 30 covers the ISP board 10, and the heat-conducting sheet 40 is attached between the heat-conducting cover plate 30 and the ISP board 10 to provide a heat conduction path.
[0046] The ISP board 10 (Image Signal Processor) is an image signal processor. Various electronic components, such as sensors, filters, and amplifiers, are typically installed on the ISP board. The ISP board 10 primarily collects, preprocesses, extracts features, reduces noise, enhances, and outputs image signals to improve image quality and clarity.
[0047] 2 and 3 , the camera 20 may be electrically connected to the ISP board 10 so that the ISP board 10 can control the camera 20. For example, the ISP board 10 is provided with a chip 12 and a connector 11. The connector 11 is configured to be electrically connected to the camera 20 so that the chip 12 can control the camera 20.
[0048] Regarding the camera 20, referring to Figures 2 and 3 , the camera 20 includes an FFC cable 21 (Flexible Flat Cable), which is electrically connected to the connector 11 of the ISP board 10 via the FFC cable 21. The FFC cable 21 is a novel data cable constructed by laminating PET (Polyethylene terephthalate) insulation and extremely thin tinned flat copper wire. It offers advantages such as flexibility, flexibility, thinness, compact size, ease of connection and disassembly, and ease of electromagnetic interference (EMI) shielding. One end of the FFC cable 21 is electrically connected to the camera 20, and the other end is electrically connected to the connector 11 of the ISP board 10 to facilitate data transmission. For example, referring to Figure 4 , the connector 11 includes a connector 111, and the FFC cable 21 includes a plug portion 211. The plug portion 211 can be inserted into the connector 111 to electrically connect the FFC cable 21 to the ISP board 10. The plug portion 111 can be a slot, and the plug portion 211 can be a plug. In some other embodiments, the FFC cable 21 is fixed to the above-mentioned connecting seat 11 by welding or clamping to achieve conduction between the camera 20 and the ISP board 10.
[0049] In some embodiments, the camera module 100 further includes a mounting bracket 50. Referring to FIG3 , the mounting bracket 50 includes a mounting platform 51, which is adapted to fit the ISP board 10. A plurality of second clips 52 are protruding from the mounting platform 51. For example, along the first direction X, the mounting platform 51 includes two long sides (not shown) that are arranged opposite to each other, and a plurality of second clips 52 are protruding from both long sides. The second clips 52 include a hook (not shown) that can be bent toward the mounting platform 51. When the ISP board 10 is placed on the mounting platform 51, the hook of the second clip 52 can be directly engaged with the ISP board 10 to secure the ISP board 10 to the mounting bracket 50. The snap connection between the ISP board 10 and the mounting bracket 50 is not only convenient for installation and disassembly, but also facilitates subsequent disassembly and maintenance.
[0050] Referring to Figures 2 and 5 , in some embodiments, the end surface of the mounting bracket 50 facing away from the mounting platform 51 further defines a mounting slot 53, into which the camera 20 is secured. After being connected to the connector 11, the FFC cable 21 extends into the mounting slot 53 and is electrically connected to the camera 20. Providing the mounting slot 53 for the camera 20 reduces the space occupied by the camera 20 and provides some protection for the camera 20, reducing the damage caused by rain, dust, and the like, thereby ensuring clear images.
[0051] Optionally, the camera module 100 includes multiple cameras 20 and multiple connectors 11. The number of cameras 20 corresponds to the number of connectors 11, that is, one camera 20 is connected to one connector 11 via an FFC cable 21. The configuration of multiple cameras 20 can increase the shooting angle to obtain more comprehensive information and perspectives, and multiple cameras 20 can simultaneously capture images to improve image clarity, contrast, and color reproduction. In addition, multiple cameras 20 can cooperate with the three-dimensional vision algorithm of the above-mentioned ISP board 10 to achieve depth perception, thereby improving the measurement and analysis capabilities of the scene, such as realizing applications such as face recognition or posture estimation.
[0052] Regarding the above-mentioned heat-conducting cover plate 30, please continue to refer to Figures 1 and 2. The heat-conducting cover plate 30 is placed on the above-mentioned ISP board 10 to cover the various electronic components on the ISP board 10, which can reduce the corrosion of various electronic components by external impurities such as moisture and dust. For example, a number of threaded holes (not marked in the figure) are provided on the heat-conducting cover plate 30, and corresponding threaded holes (not marked in the figure) are also provided on the above-mentioned mounting bracket 50. The heat-conducting cover plate 30 can be fixed to the mounting bracket 50 by screws, and the heat-conducting cover plate 30 just covers the above-mentioned ISP board 10. In some other embodiments, the heat-conducting cover plate 30 can also be connected to the mounting bracket 50 by bonding or clamping, etc., which is not limited in this application.
[0053] In some embodiments, the thermally conductive cover plate 30 includes a base material portion and a thermally conductive material portion. The base material portion includes at least one of PPS (polyphenylene sulfide), PA6 (polyamide 6), PA66 (polyamide 66), LCP (liquid crystal polymer), TPE (thermoplastic elastomer), PC (polycarbonate), PP (polypropylene), PPA (polyphosphoric acid), and PEEK (polyetheretherketone). The thermally conductive material portion includes at least one of AlN (aluminum nitride), SiC (silicon carbide), Al2O3 (aluminum oxide), graphite, fibrous high thermal conductivity carbon powder, and flaky high thermal conductivity carbon powder. The aforementioned non-metallic base material is stable and not easily corroded by external impurities such as rain, dust, and the like. Therefore, there is no need for a shielding structure on the outer surface of the heat-conducting cover plate 30, simplifying maintenance and extending the service life of the heat-conducting cover plate 30. Furthermore, the addition of a metal heat-conducting material with excellent thermal conductivity can enhance the thermal conductivity of the heat-conducting cover plate 30. The combination of the base material and the heat-conducting material ensures that the heat-conducting cover plate 30 has excellent thermal conductivity and a long service life.
[0054] Referring to Figures 2, 6, and 7, an elastic bracket 31 is protruding from the end surface of the heat-conducting cover plate 30 facing the ISP board 10. The elastic bracket 31 is supported between the heat-conducting cover plate 30 and the plug-in portion 211. The elastic bracket 31 corresponds to the position of the connector 11. When the heat-conducting cover plate 30 is placed on the ISP board 10, the elastic bracket 31 just presses the plug-in portion 211 plugged into the connector 11, providing an elastic pressing force of the plug-in portion 211 on the connector 11, ensuring that the plug-in portion 211 is stably plugged into the plug position 111, thereby ensuring a stable electrical connection between the FFC cable 21 and the connector 11.
[0055] Because the heat-conducting cover plate 30 itself is made of the aforementioned various types of plastic materials, the elastic bracket 31 can be integrally formed with the heat-conducting cover plate 30, ensuring the connection strength between the elastic bracket 31 and the heat-conducting cover plate 30, thereby ensuring a stable connection and stabilizing the crimping of the plug portion 211. Compared to conventional foam crimping, the elastic bracket 31 has better crimping stability. Moreover, the plastic elastic bracket 31 itself has a certain degree of flexibility, which means that it can be directly crimped to the connector 11 through the elastic bracket 31, which saves foam. Moreover, during installation, the foam needs to be positioned by marking the heat-conducting cover plate 30, and the elastic bracket 31 can save this marking step. At the same time, the foam itself is soft and easily absorbs water. After long-term crimping of the plug portion 211, it is prone to plastic deformation, causing the plug portion 211 and the connector 11 to loosen. The temperature difference between the internal and external environments may also cause water vapor to adhere to the foam, which may cause the plug portion 211 to short-circuit and fail. In this embodiment, the use of the elastic bracket 31 can solve such problems.
[0056] Continuing with Figures 2 and 6 , the end surface of the heat-conducting cover plate 30 facing the ISP board 10 is provided with a plurality of reinforcing ribs 32. The provision of the reinforcing ribs 32 increases the strength of the heat-conducting cover plate 30 and reduces deformation of the heat-conducting cover plate 30. Some of the reinforcing ribs 32 can be arranged horizontally on the end surface, while others can be arranged longitudinally. This staggered arrangement prevents bending and deformation of the heat-conducting cover plate 30 in all directions.
[0057] 6 to 8 , in some embodiments, the elastic bracket 31 includes a first connector 311, a second connector 312, and a supporting member 313. The first connector 311 and the second connector 312 are disposed opposite each other. The first connector 311 includes a first section 3111 and a second section 3112. The first section 3111 can be connected to the end surface of the heat-conducting cover plate 30 facing the ISP board 10, and the first section 3111 is bent toward the second connector 312. The second section 3112 is connected to the end of the first section 3111 facing away from the heat-conducting cover plate 30, and the second section 3112 is bent away from the second connector 312. The second connector 312 includes a third section 3121 and a fourth section 3122. The third section 3121 is connected to the heat-conducting cover plate 30 and is bent toward the first connector 311. The fourth section 3122 is connected to the end of the third section 3121 facing away from the heat-conducting cover plate 30 and is bent away from the first connector 311. The abutting member 313 has one end connected to the end surface of the second section 3112 facing away from the first section 3111 and the other end connected to the end surface of the fourth section 3122 facing away from the third section 3121. The abutting member 313 is configured to abut against the plug portion 211 and provide a pressing force for the plug portion 211 toward the connector 11.
[0058] The above-mentioned first section 3111 and the third section 3121 gradually approach each other, while the second section 3112 and the fourth section 3122 gradually move away from each other, so that the first section 3111, the second section 3112, the third section 3121 and the fourth section 3122 can enclose a buffer space A. When the supporting member 313 is subjected to force, the connection between the first section 3111 and the second section 3112 gradually approaches the connection between the third section 3121 and the fourth section 3122, thereby forming a buffer space A for the supporting member 313 to press the connecting seat 11, which can reduce friction damage to the connecting seat 11 while pressing the connecting seat 11.
[0059] Optionally, two flexible pads 3131 may be provided on the supporting member 313, with a positioning space formed between the two flexible pads 3131. This positioning space is compatible with the aforementioned connecting base 11. When the thermal conductive cover 30 is placed on the ISP board 10, the connecting base 11 is sandwiched between the two flexible pads 3131. The provision of two flexible pads 3131 facilitates the positioning of the elastic bracket 31, thereby ensuring stable crimping of the connecting base 11. Alternatively, in other embodiments, the flexible pads 3131 may be directly crimped to the connecting base 11.
[0060] When multiple cameras 20 are set up, the number of connecting sockets 11 is also multiple. At this time, the number of elastic brackets 31 corresponds one-to-one to the connecting sockets 11. One elastic bracket 31 is crimped to one connecting socket 11, which can provide a separate camera channel for each camera 20 to obtain more comprehensive information and viewing angles.
[0061] Continuing with Figure 2 , the thermal pad 40 is attached between the cover plate and the chip 12. For example, the thermal pad 40 is positioned on the end surface of the thermally conductive cover plate 30 facing the ISP board 10. When the thermally conductive cover plate 30 is positioned over the thermal pad 40, it precisely aligns with the chip 12 on the ISP board. As the primary heat source, the chip 12 generates a significant amount of heat during operation. This heat is transferred through the thermal pad 40 to the thermally conductive cover plate 30. Because the thermally conductive cover plate 30 itself includes a portion of heat-conducting material, it dissipates the heat to the outside, thereby improving the heat dissipation efficiency of the chip 12.
[0062] Please refer to Figures 2 and 6. The connection between the heat conducting sheet 40 and the heat conducting cover plate 30 can be achieved by snap-fitting. For example, the end surface of the heat conducting cover plate 30 facing the ISP board 10 is provided with a plurality of first snap-fitting buckles 33. The plurality of first snap-fitting buckles 33 enclose a first snap-fitting space B (the dotted portion in Figure 6). The heat conducting sheet 40 is provided in the first snap-fitting space B and snap-fitted with the plurality of first snap-fitting buckles 33 so that the heat conducting sheet 40 is fixed to the heat conducting cover plate 30. The snap-fitting method can facilitate the installation of the heat conducting sheet 40 and also facilitate the subsequent disassembly and maintenance. In some other embodiments, the heat conducting sheet 40 can also be connected by bonding or screw connection, which is not limited in this application.
[0063] Observing from the direction from the heat conducting plate 40 to the chip 12 (second direction Z), the heat conducting plate 40 completely covers the chip 12, so that the chip 12 and the heat conducting plate 40 are in full contact, increasing the contact area and thus improving the heat conduction efficiency. In addition, the complete coverage can also avoid the interference of the first clip 33 on the chip 12.
[0064] Optionally, referring to FIG. 2 , in some embodiments, a thermally conductive silicone layer 60 may be provided between the thermally conductive sheet 40 and the chip 12. The thermally conductive silicone layer 60 fills the gap between the thermally conductive sheet 40 and the chip 12, further improving the heat conduction efficiency between the thermally conductive sheet 40 and the chip 12, thereby improving the heat dissipation performance of the chip 12. Furthermore, the thermally conductive silicone layer 40 acts as a buffer to prevent direct rigid contact between the chip 12 and the thermally conductive sheet 40, thereby reducing pressure damage to the chip 12.
[0065] In the embodiment of the present application, by disposing a heat conducting sheet 40 between the heat conducting cover plate 30 and the chip 12, the heat generated by the chip 12 during operation can be transferred to the heat conducting sheet 40 through the heat conducting sheet 40, and then conducted to the heat conducting cover plate 30 through the heat conducting sheet 40, and finally dissipated from the heat conducting cover plate 30 to the outside world, which can improve the heat dissipation efficiency of the chip 12 and ensure the stable operation of the camera module 100. At the same time, the heat conducting cover plate 30 has an elastic bracket 31 for crimping the connector 11. The elastic bracket 31 can apply an elastic force to the connector 11 and the plug-in portion 211 of the FFC cable 21, so that the FFC cable 21 is stably electrically connected to the connector 11, thereby ensuring the stable operation of the camera 20.
[0066] In the second aspect, an embodiment of the present application further proposes an interactive smart tablet 1000. Please refer to Figure 9. The interactive smart tablet 1000 includes the camera module 100 as described in any embodiment of the first aspect above.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Based on the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present application as described above. For the sake of simplicity, they are not provided in detail. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
