[0032] In related technologies, as electronic devices become thinner and lighter, their internal structures are stacked more tightly, making camera modules highly susceptible to interference from surrounding antennas, leading to malfunctions such as crashes and stuttering. However, grounding the circuit can only shield some interference paths and cannot solve the electromagnetic interference problems caused by other interference paths.

[0033] This disclosure provides a camera module. Figure 1 This is a schematic diagram of the structure of a camera module according to an exemplary embodiment of this disclosure, as shown below. Figure 1 As shown, Figure 1 The dashed arrow represents the optical axis extension direction of the lens body 111. The camera module 1 includes a lens assembly 11, a camera circuit board 12, a connector assembly 13, and a conductive structure 17. The lens assembly 11 includes a lens body 111 and a lens housing 112. The lens body 111 is assembled on the device motherboard 21, and at least a portion of the lens body 111 is housed within the lens housing 112. The connector assembly 13 is assembled on the device motherboard 21, and a gap 16 is provided between the connector assembly 13 and the lens assembly 11 in the projection direction parallel to the optical axis of the lens body 111. The connector assembly 13 is electrically connected to the camera circuit board 12 through a connection line 14 located at the gap 16. The conductive structure 17 is disposed on the connector assembly 13, and the conductive structure 17 is connected to the lens housing 112 via the gap 16.

[0034] In the above embodiments, the camera circuit board 12 may be equipped with electronic components such as an image sensor, and the connection between the camera circuit board 12 and the connector assembly 13 can realize the transmission of signals such as image signals and control signals.

[0035] A gap 16 is provided between the connector assembly 13 and the lens assembly 11 in the projection direction parallel to the optical axis of the lens body 111. The camera circuit board 12 is electrically connected to the connector assembly 13 through the connecting line 14 located within the gap 16. Based on the property that current always flows to the place with lower impedance, the impedance of the conductive structure 17 connecting the lens housing 112 and the connector assembly 13 through the gap 16 is lower than that of other locations. Therefore, it can be used to cut off the electromagnetic radiation that interferes with the operation of the connecting line 14 and the lens assembly 11 through the gap 16, thereby avoiding problems such as lens assembly 11 malfunctioning or jamming. The simple structural design effectively and directly improves the reliability of the camera module 1 and the electronic device.

[0036] It should be noted that, since the antennas and other radiating components of the electronic device generate an electric field around the camera module 1, the metal components surrounding the camera module 1 and the connector assembly 13, as well as the lens housing 112 of the camera module 1, will resonate strongly based on this electric field. The conductive structure 17, applied in this scenario, can cut off the radiation path located at interval 16, reducing the field strength interference experienced by this part of the camera module 1 and the connecting lines 14. The aforementioned metal components surrounding the camera module 1 can be metal decorative parts 15, or reinforcing components, mid-frames, or other structures of the electronic device; this disclosure does not impose any limitations on this.

[0037] Taking the metal decorative part 15 as an example, the metal decorative part 15 can be a structure used to decorate the camera, so that the camera module 1 can achieve an appearance that matches the overall electronic device. In some embodiments, the camera module 1 includes the decorative part 15. In a direction parallel to the optical axis of the lens body 111, at least a portion of the decorative part 15 is located on top of the connector assembly 13, and at least a portion of the conductive structure 17 is located between the connector assembly 13 and the decorative part 15. The conductive structure 17 can utilize the structure located between the connector assembly 13 and the decorative part 15 in a direction parallel to the optical axis of the lens body 111 to isolate and shield electromagnetic interference acting on the connector assembly 13 through the space between the connector assembly 13 and the decorative part 15, further improving the shielding effect of the conductive structure 17.

[0038] For example, in a direction parallel to the optical axis of the lens body 111, the projection of the decorative element 15 onto the first side 1311 of the connector assembly 13 facing the decorative element 15 is a third region. The conductive structure 17 can cover the third region to improve the shielding effect of the conductive structure 17 on the electromagnetic field of this part and reduce the effect of electromagnetic interference on the connector assembly 13.

[0039] In other embodiments, the connector assembly 13 includes a first side 1311 facing away from the device motherboard 21, and a conductive structure 17 covers the first side 1311. Covering the side facing away from the device motherboard 21 with the conductive structure 17 isolates external electromagnetic interference acting on the connector assembly 13 from that side, improving signal transmission performance.

[0040] In some embodiments, the aforementioned interval 16 has an opening 161 at its top along the optical axis of the lens body 111. The conductive structure 17 includes a plate-like structure connecting the connector assembly 13 and the lens housing 112, and the plate-like structure covers the opening 161. By covering the opening 161 with the plate-like structure, electromagnetic interference can be cut off from the entrance of the interval 16, improving the routing flexibility of the connection lines 14 in the space of the interval 16, and minimizing the interference of electromagnetic fields on adjacent components of the interval 16.

[0041] It should be noted that the conductive structure 17 described above can be one of conductive cloth or copper foil to improve the magnetic field shielding effect. The material of the conductive structure 17 can also be other metals, and this disclosure does not limit this. Alternatively, the conductive structure 17 can also be in the form of strips, lines, blocks, etc., and this disclosure does not limit the shape of the conductive structure 17.

[0042] In some embodiments, the connector assembly 13 includes a first circuit board 131 and a connector body 132 disposed on the first circuit board 131. The camera circuit board 12 is disposed at the bottom of the lens body 111 in the optical axis direction. The connection line 14 includes a flexible circuit board connecting the first circuit board 131 and the camera circuit board 12. By providing the first circuit board 131 for the connector body 132, and connecting the first circuit board 131 and the camera circuit board 12 through the flexible circuit board, signal transmission connection with the device motherboard 21 can be achieved, simplifying the structural setup.

[0043] In other embodiments, the connection line 14 may also be a wire, a rigid circuit board, etc., and this disclosure does not limit it.

[0044] In the above embodiments, the connection line 14 may include MIPI (Mobile Industry Processor Interface) traces for achieving high-speed, low-power transmission requirements. The conductive structure 17 can shield the MIPI traces and MIPI interface from the antenna of the electronic device, thus preventing the camera module 1 from experiencing problems such as crashes and stuttering due to electromagnetic interference.

[0045] In some embodiments, the device motherboard 21 is provided with a mounting hole 211, the lens assembly 11 is embedded in the mounting hole 211, and a first region 212 adjacent to the mounting hole 211 is provided on a second side of the device motherboard 21, and the connector assembly 13 is assembled in the first region 212. The lens assembly 11 is embedded in the device motherboard 21, which allows for flexible adjustment of the relative positional relationship between the connector assembly 13 and the camera circuit board 12 in the direction parallel to the optical axis, thereby improving the convenience and reliability of conductive connection.

[0046] In other embodiments, the second side of the device motherboard 21 includes a first region 212 and a second region disposed adjacent to each other, with the lens assembly 11 assembled in the second region and the connector assembly 13 assembled in the first region 212. The connector assembly 13 and the lens assembly 11 can be assembled in adjacent regions on the same side of the device motherboard 21 to facilitate conductive connection.

[0047] In the above embodiments, the first region 212 may be located at the edge of the device motherboard 21 to avoid the influence of the wiring connection on the layout of other electronic components on the device motherboard 21 and improve the structural utilization of the device motherboard 21.

[0048] It should be noted that the lens housing 112 can be made of metal.

[0049] This disclosure further provides an electronic device, which includes the aforementioned camera module 1.

[0050] A gap 16 is provided between the connector assembly 13 and the lens assembly 11 in the projection direction parallel to the optical axis of the lens body 111. The camera circuit board 12 is electrically connected to the connector assembly 13 through the connecting line 14 located within the gap 16. Based on the property that current always flows to the place with lower impedance, the impedance of the conductive structure 17 connecting the lens housing 112 and the connector assembly 13 through the gap 16 is lower than that of other locations. Therefore, it can be used to cut off the electromagnetic radiation that interferes with the operation of the connecting line 14 and the lens assembly 11 through the gap 16, thereby avoiding problems such as lens assembly 11 malfunctioning or jamming. The simple structural design effectively and directly improves the reliability of the camera module 1 and the electronic device.

[0051] Furthermore, the aforementioned electronic device may include an antenna located around the camera module 1. For example, the frequency band of the antenna may be N77, WIFI 5G, etc. Taking the frequency band of the antenna around the camera module 1 as N77 and WIFI 5G as an example... Figure 2 This is an isolation curve from the WIFI 5G antenna feed port to the connector assembly 13 port in an exemplary embodiment of this disclosure. Figure 2 As can be seen, in the 5G WIFI band, S1 is the curve before optimization, and S2 is the curve after optimization. Using this solution can improve the anti-interference margin by about 9.6dB. Figure 3 This is an isolation curve from the N77 antenna feed port to the connector assembly 13 port in an exemplary embodiment of this disclosure. Figure 3 As can be seen, in the N77 band, S3 is the curve before optimization, and S4 is the curve after optimization. Using this solution can improve the anti-interference margin by about 7.7dB.

[0052] It should be noted that the aforementioned electronic devices may be mobile phones, tablets, in-vehicle terminals, medical terminals, wearable devices, etc., and this disclosure does not impose any restrictions on them.

[0053] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure in any way. Although this disclosure has been disclosed above with reference to a preferred embodiment, it is not intended to limit this disclosure. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this disclosure.
