[0025] In the present disclosure, the orientation words such as "inner, outer" used without the opposite description refer to the inner and outer relative to the outline of the component or structure itself. In addition, it should be noted that the terms such as "first, second" used are for distinguishing one element from another element, and do not have sequential and important meanings. In addition, in the description with reference to the drawings, the same reference numerals represent the same elements in different drawings.

[0026] According to a first aspect of the present disclosure, there is provided a mounting seat of a camera module. Referring to Figure 1 to FIG. Figure 5As shown, the mounting seat includes a lens holder 10 and a circuit board 20. The lens holder 10 has a first side for mounting a lens assembly 30, and the circuit board 20 is connected to the lens holder 10 and includes a first circuit board portion 21 and a second circuit board portion 22, the first circuit board portion 21 is arranged facing a second side of the lens holder 10 opposite to the first side, and the second circuit board portion 22 is arranged around at least a part of a periphery of the first circuit board portion 21 and extends towards a side where the lens holder 10 is located, the lens holder 10 and the circuit board 20 together enclose a mounting space for mounting circuit devices, the circuit devices include an image sensor 40 arranged on the first circuit board portion 21 and a component 50 arranged on the second circuit board portion 22, and the lens holder 10 is formed with a light hole 14 penetrating the first side and the second side, so that the image sensor 40 can receive a light signal from the lens assembly 30.

[0027] By the above technical solution, the component is arranged on the side wall of the second circuit board portion 22 arranged around at least a part of the periphery of the first circuit board portion 21, which can solve the problem of low utilization rate of internal space of the camera module in the related art. Specifically, the image sensor 40 can be arranged on the first circuit board portion 21, and the components 50 other than the image sensor 40, such as capacitors, resistors or driver chips, etc. can be arranged on the second circuit board portion 22, so as to improve the utilization rate of the internal space of the camera module and reduce the overall size of the camera module. Therefore, the camera module provided by the present disclosure has the advantages of high space utilization rate and small overall occupied space.

[0028] The component 50 can include, for example, capacitors, resistors and / or driver chips. The capacitors can be arranged side by side to fully utilize the space on the second circuit board portion 22. The driver chips (Driver IC) can be used in an AF (Auto Focus) module to drive a VCM (Voice Coil Motor). In addition, the component 50 can be soldered to the second circuit board 22 by, for example, SMT (Surface Mounted Technology). In addition, the component 50 can also include other electronic components for the camera module, which are not specifically limited in the present disclosure. By mounting the component 50 on the second circuit board portion 22, the size of the camera module can be prevented from continuously increasing as the size of the image sensor or the photosensitive chip increases, the space around the image sensor can be fully utilized, and the space utilization rate can be improved.

[0029] In addition, the image sensor 40 (Sensor) can be arranged on the first circuit board portion 21 in any suitable manner. For example, in some embodiments, the image sensor 40 can be bonded to the first circuit board portion 21 by, for example, glue and connected by gold wires.

[0030] The circuit board 20 can be constructed in any suitable manner according to actual application requirements, for example, in some embodiments, as shown in Figure 2 and Figure 4 the circuit board 20 can be a flexible circuit board (FPC), and the first circuit board portion 21 and the second circuit board portion 22 are bent through the circuit board 20. In this way, the manufacturing cost can be significantly reduced and the production efficiency can be improved.

[0031] In order to further reasonably and sufficiently utilize the installation space enclosed by the lens holder 10 and the circuit board 20, in some embodiments, as shown in Figure 4 and Figure 5 the second circuit board portion 22 is connected to the lens holder 10, and the lens holder 10 is provided with an opening 11 for avoiding the components 50.

In this way, the mounting seat can save the occupied space while having good support, and the mounting space in the mounting seat also has a rectangular cross section, which is beneficial to the arrangement of the image sensor 40 and the components 50. In addition, the end of the second circuit board portion 22 opposite to the first circuit board portion 21 can be used to connect with the connector 70, so as to be electrically connected with the electronic equipment in which the camera module is installed through the connector 70.

[0034] In some embodiments, as shown in Figure 2 and Figure 4As shown, the light passing hole 14 is used to set the filter 60 between the image sensor 40 and the lens 31. The filter 60 can adopt, for example, an infrared filter (IR filter) for filtering infrared light, avoiding the interference of infrared light to the normal imaging of the image sensor, and improving the imaging quality.
