Description

Technical Field

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

[0002] With the increasing demand for cameras in the fields of artificial intelligence and robotics, and the requirement for miniaturization, cameras generally consist of a housing and internal components such as a PCBA board, ISP debugging board, CCD, and lens. Generally, the imaging data needs to be transmitted to the application device for data processing and application. However, the overall size of the camera is relatively large, and the corresponding data cannot be directly processed and transmitted to the application inside the camera. This also requires the addition of corresponding processing modules in artificial intelligence and robotics devices, affecting the highly integrated structure of artificial intelligence and robotics devices.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] See Figures 1-6As shown in the figure, an embodiment of this utility model proposes a camera module, including an upper cover 1 and a lower cover 2 sealed to the upper cover 1. The upper cover 1 is provided with a first stepped groove 3 and two mounting seats 4 located in the first stepped groove 3 and arranged opposite to each other. The upper cover 1 has a first through hole 5 communicating with the first stepped groove 3. A PCBA board 6 is installed in the first stepped groove 3. The PCBA board 6 has a limiting notch 7 to avoid the mounting seats 4. A smart sensor module 8 is integrated on the PCBA board 6. A device is installed in the first through hole 5 that is connected to the smart sensor module 8. The corresponding lens 9 is mounted on two mounting bases 4, and an ISP debugging board 10 is mounted on the lower cover 2. The connector 11 is connected to the ISP debugging board 10, and the ISP debugging board 10 is connected to the PCBA board 6. By setting a first stepped groove 3 to place the PCBA board 6, and setting a limiting notch 7 to avoid the mounting base 4, the PCBA board 6 can be as close as possible to the bottom of the first stepped groove 3. The ISP debugging board 10 is mounted on the mounting base 4 and can be inserted into the PCBA board 6. Thus, the internal electrical components are integrated in a very small internal space. At the same time, the lens 9 is placed in the first through hole 5 and extends out of the upper cover 1, while the connector 11 is placed in the lower cover 2 and the connecting part extends outward, further reducing the internal space occupied and achieving a very small size.

[0029] Meanwhile, a foolproof block 26 is provided in the first step groove 3, and a foolproof notch is provided on the PCBA board 6. The foolproof notch engages with the foolproof block 26 to ensure that the installation direction and position of the PCBA board 6 after it is installed in the first step groove 3 will not be incorrect, further ensuring the correct installation of the subsequent ISP debugging board 10.

[0030] By integrating the intelligent sensor module 8 on the PCBA board 6, the imaging function and micro-information processing function are integrated into the camera module, thereby enabling the processed data to be transmitted to the outside for direct application. Furthermore, some components in the PCBA board 6 can be eliminated, further reducing the size of the PCBA board 6 and facilitating the minimization of internal space.

[0031] The intelligent sensor module 8 includes an integrated portion 81 and a photosensitive portion 82 disposed on the integrated portion 81. The photosensitive portion 82 is provided with a light-transmitting glass 83. The integrated portion 81 includes an electrically connected sensor, a microprocessor, and an integrated circuit. The entire intelligent sensor module 8 uses mature products, mainly due to its highly sensitive photosensitive portion 82 and the highly integrated integrated portion 81, which has a microprocessor that can realize imaging and information processing functions. Generally speaking, using the intelligent sensor module 8 can reduce the number of components on the PCBA board 6, making the size of the PCBA board 6 smaller.

[0032] Specifically, a second stepped groove 12 is provided at the bottom of the lower cover 2, and a connecting part is provided on the connector 11. The connecting part is embedded in the second stepped groove 12. A first sealing groove 13 and a first sealing ring 14 located in the first sealing groove 13 are provided on the connector 11. The first sealing ring 14 abuts against the bottom surface of the second stepped groove 12. A second through hole 15 is provided at the bottom of the second stepped groove 12, which extends into the connecting part of the connector 11. The connecting part of the connector 11 is inserted into the ISP debugging board 10 through the second through hole 15 and positioned in the second stepped groove 12. Under the action of the first sealing ring 14, the connection sealing performance between the connector 11 and the lower cover 2 is achieved.

[0033] Specifically, the upper cover 1 is provided with a sealing protrusion 16, and the lower cover 2 is provided with a second sealing groove 17 and a second sealing ring disposed in the second sealing groove 17. By inserting the sealing protrusion 16 into the second sealing groove 17 and pressing the second sealing ring, a reliable seal is achieved between the upper cover 1 and the lower cover 2, thereby giving the internal space good sealing performance.

[0034] Specifically, when assembling the upper cover 1 and the lower cover 2, it is necessary to prevent mistaken installation and avoid incorrect installation direction. An alignment notch 18 is provided at one corner of the upper cover 1, and an alignment boss 19 is provided at one corner of the lower cover 2 to cooperate with the alignment notch 18. The installation positions of the upper cover 1 and the lower cover 2 are matched by the cooperation of the alignment boss 19 and the alignment notch 18.

[0035] Meanwhile, the lower cover 2 is provided with a groove 20 to accommodate the ISP debugging board 10. The groove 20 is provided with a pressing boss 21 for pressing the ISP debugging board 10. After the upper cover 1 and the lower cover 2 are accurately matched, the pressing boss 21 presses and limits the ISP debugging board 10, which has a certain anti-vibration effect.

[0036] Meanwhile, a plug-in portion 22 is provided on the part of the connector 11 located on the outside of the lower cover 2. The plug-in portion 22 is provided with a hook 23 and a limiting portion 24 located on both sides of the hook 23. The hook 23 and the limiting portion 24 are positioned during plug-in installation. At the same time, a positioning protrusion 25 is provided at the bottom of the lower cover 2 on one side of the connector 11. The positioning protrusion 25 is used to match the installation angle positioning of the entire camera module.
