The following describes the camera module provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1 to 10, the camera module includes:

a lens assembly 101;

a first circuit board 102, wherein an imaging chip 1021 is arranged on the first circuit board 102;

The imaging chip 1021 may be used to convert the optical signal into an electrical signal.

It should be noted that, because the models of the current terminals all carry large-substrate chips to obtain higher image quality, better experience can be brought to consumers. However, the large-substrate chip must be used in combination with the larger lens 1011, in order to match the chip with higher resolution, the number of lenses in the lens 1011 is increased continuously, and in order to achieve better imaging effect, the glass lens with higher refractive index is used to replace the original plastic lens, so that the weight of the lens 1011 is increased continuously. Because the motor is adopted to push the lens 1011 in the prior art, the motor is required to generate larger thrust in the process of realizing focusing, and the thrust comes from electric energy, so that the power consumption of the motor is increased, and the power consumption for driving the lens 1011 is higher and higher. In the embodiment, the driving mechanism drives the carrier 103 to move so as to drive the imaging chip 1021 to move towards or away from the lens assembly 101, so that the power consumption of the camera can be reduced.

In the embodiment of the present application, focusing is achieved by using a mode of moving the imaging chip 1021 instead of a mode of moving the lens 1011 in the prior art. The essence of camera focusing is that the distance between the lens 1011 and the imaging chip 1021 varies. In the prior art, the moving parts of the auto-focusing camera are a motor and a lens 1011 driven by the motor, the imaging chip 1021 and other optical parts are kept still, and the motor pushes the lens 1011 to adjust the distance from the lens 1011 to the imaging chip 1021, so that the effect of clear focusing at different distances is achieved. In this embodiment, the lens 1011 and the motor are used as fixed components, and the automatic focusing effect is achieved by adjusting the distance from the imaging chip 1021 to the lens 1011, so that the lens 1011 remains still and the reliability can be improved. For the scheme that lens subassembly 101 reciprocated among the prior art, need set up great silk screen printing windowing on the camera protection cover, the casing 1012 is windowed also great simultaneously, and the silk screen printing windowing can be reduced to this embodiment, and the shell of lens subassembly 101 can be done little trompil and cover inside components, and lens 1011 can need not to be "mushroom head", can improve pleasing to the eye degree.

In this embodiment, the lens 1011 in the camera module is fixed, and focusing is achieved by changing the relative positions of the imaging chip 1021 and the lens assembly 101, so that power consumption can be reduced to a greater extent, and therefore the imaging chip 1021 can be matched with a larger-sized lens 1011. The lens 1011 does not need to reserve a space for dust-proof foam on a screen or a battery rear cover, and the lens 1011 can directly contact the dust-proof foam, so that the dust-proof effect is improved, the whole machine is favorably designed to be thinner, and better vision and hand feeling can be provided for a user; for the ultra-wide-angle camera, a 'mushroom head' which is used for shielding the shell 1012 and a gap between the lens 1011 and the shell 1012 can be added to shield the shell 1012 to a greater extent, so that the precision of the whole machine is improved.
