In this embodiment, please refer to fig. 4 and 7, the flexible circuit board 150 includes a first flexible circuit board 151 and a second flexible circuit board 152, wherein a first end 153 of the first flexible circuit board 151 is electrically connected to the first side 111, then extends to a first side 1231 of the motor 120 and is attached to the first side 1231, then bends to a third side 1233, a second end 154 is attached to the third side 1233, a first end 153 of the second flexible circuit board 152 is electrically connected to the second side 112, then extends to a second side 1232 of the motor 120 and is attached to the first side 1231, then bends to the third side 1233, and a second end 154 is attached to the third side 1233. Namely, the first flexible circuit board 151 and the second flexible circuit board 152 are connected to the circuit board 110 from both sides of the circuit board 110, respectively. In this embodiment, the flexible circuit board 150 may be routed entirely along the side 123 of the motor 120 without additional space occupation.

Referring to fig. 7 and 8, the second end 154 of the first flexible circuit board 151 and the second end 154 of the second flexible circuit board 152 can be directly electrically connected to the control coil 127. In this embodiment, the second end 154 of the first flexible circuit board 151 is provided with the first through holes 155, and the number of the first through holes 155 may be plural, which is not limited herein. The first through hole 155 is filled with metal solder, and the metal solder is electrically connected with the control coil 127, namely, the metal solder is electrically connected in a stamp hole welding mode. In addition, the second end 154 of the second flexible circuit board 152 may also be provided with a second through hole 156, and the number of the second through holes 156 may be plural, which is not limited herein. The second through hole 156 is filled with metal solder, and the metal solder is electrically connected with the control coil 127, i.e., connected in the same connection manner as the first flexible circuit board 151. In another embodiment, the second end 154 of the first flexible circuit board 151 and the second end 154 of the second flexible circuit board 152 may also be disposed in a corresponding overlapping manner, where the first through hole 155 may completely correspond to the second through hole 156, and the metal solder may directly fill the first through hole 155 and the second through hole 156 at the same time and be electrically connected to the control coil 127, so as to achieve conduction.

The first end 153 of the first flexible circuit board 151 may be connected to the circuit board 110 by integrally combining, or the first end 153 of the first flexible circuit board 151 may be connected to the circuit board 110 by the connector 160.

Here, the present application is not limited to any specific one.

The "metal solder" may be, for example, tin, lead, or the like, and is not particularly limited herein.

In the solder soldering process, when the first through hole 155 and the second through hole 156 are aligned with the metal contact 128 on the third side surface 1233, the first flexible circuit board 151 and the second flexible circuit board 152 may form a shielding for the third side surface 1233, so that the first through hole and the second through hole cannot be aligned accurately during soldering, and poor soldering inclination is easily caused. In order to facilitate the operation during the soldering process, as an embodiment, the second end 154 of the second flexible circuit board 152 is provided with a notch 157 and a second through hole 156, the second through hole 156 is disposed adjacent to the notch 157, that is, the second through hole 156 is opened at a position of the geothermal flexible circuit board 150 near the notch 157, the second end 154 of the second flexible circuit board 152 is attached to the third side 1233, the second end 154 of the first flexible circuit board 151 is attached to the second flexible circuit board 152, and a part of the first through hole 155 corresponds to the notch 157 and is electrically connected to the control coil 127 through metal solder, so that an operator or an operation device can more accurately align the metal solder with the metal contacts 128 on the first through hole 155 and the third side 1233 during the soldering process. The remaining first through holes 155 and the second through holes 156 correspond to each other, and the first through holes 155 and the second through holes 156 are filled with metal solder, and the metal solder-connects only the first flexible circuit board 151 and the second flexible circuit board 152 by soldering at the portions corresponding to the first through holes 155 and the second through holes 156. In this connection mode, the first flexible circuit board 151 and the second flexible circuit board 152 are not required to be welded with the control coil 127 of the motor 120 at the same time, only the first flexible circuit board 151 is required to be welded with the control coil 127 of the motor 120, and the second flexible circuit board 152 is only required to be connected with the first flexible circuit board 151, so that the welding operation is facilitated, and the welding stability is ensured.

Because the first flexible circuit board 151 and the second flexible circuit board 152 are all along the third side surface 1233 or the first side surface 1231 or the second side surface 1232 when wiring, no more space size is generated for the whole camera module 100, and thus the space occupation of the whole camera module 100 when mounting can be reduced. In addition, since the flexible circuit board 150 is soldered only from one direction of the third side 1233 of the motor 120, the operation is simpler and the process cost is lower than the prior art in which the soldering leg is soldered from both sides 123 of the motor 120 at the same time.

Further, the connector 160 may be connected to the first flexible circuit board 151, and directly connected to the motherboard 50 through the connector 160, so that the flexible circuit board 150 connected to the connector 160 is not required to be separately arranged, which is convenient for assembly and reduces the length of the circuit board 110.

The camera module 100 described above may be assembled as follows:

firstly, the photosensitive chip 170 is attached to the circuit board 110, after the motor 120 is integrally mounted on the circuit board 110, the photosensitive chip 170 is located in the mounting hole 129, then the second end 154 of the first flexible circuit board 151 and the second end 154 of the second flexible circuit board 152 bypass the first side face 1231 and the second side face 1232 respectively, are attached to the third side face 1233, and are welded and fixed with the first flexible circuit board 151 and the second flexible circuit board 152 by means of laser welding and the like, so that electric connection is achieved. The whole assembly process is simpler, so the process cost is lower.

In some embodiments, the electronic device 10 may further include a camera trim, where the camera trim is disposed in the mounting hole 263, and the camera module 100 may be exposed from the mounting hole 263, and the camera trim may serve as a sealing mounting structure of the camera module 100, and may play a role in decorating an external appearance, and provide a sealing effect at the mounting hole 263.

In the camera module 100 and the electronic device 10 provided in the present embodiment, the flexible circuit board 150 is connected to the side face 123 of the motor 120, so that the assembly process can be greatly reduced, and the process cost can be reduced. Meanwhile, the problem of space occupation increase caused by arrangement of welding legs is solved. Because the flexible circuit board 150 can be tightly attached to the side 123 of the motor 120 during wiring, the space occupation of the motor 120 is not increased during wiring, so that the size of the whole camera module 100 is reduced, and the space occupation of the camera module 100 during mounting is further reduced.

The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
