Here, since the first lens group 51 is fixed in the first barrel 54, the second driving mechanism 4 is connected to the first barrel 54, and drives the first barrel 54 to move, that is, the first lens group 51 to move.

Based on this, in order to realize that the first lens barrel 54 moves relative to the second lens barrel 55 under the driving action of the second driving mechanism 4, referring to fig. 3, as an alternative implementation manner, the third side wall of the second lens barrel 55 is provided with a limiting groove 7; a first connecting piece 8 is arranged on the fourth side wall of the first lens barrel, and the first connecting piece 8 is clamped with the limiting groove 7; under the condition that the second driving mechanism 4 drives the first lens barrel 54 to move through the first connecting piece 8, the first connecting piece 8 can move along the length direction of the limiting groove 7.

Here, the third sidewall of the second barrel 55 is adjacent to the second sidewall of the second barrel 55.

As an alternative implementation manner, referring to fig. 5, the second barrel 55 is fixed to the second housing 2, the second driving mechanism 4 is fixed to the first housing 1, and a predetermined region 9 (see fig. 8) of the first housing 1 has light transmittance; when the second driving mechanism 4 drives the first lens group 51 to move, the preset area covers the movement area of the first lens group 51.

Here, since the first lens group 51 moves during the optical zooming process, that is, the position of the incident light entering the first lens group 51 is changed, in order not to affect the incident light entering the first lens group 51, the area of the first housing 1 (i.e. the predetermined area 9) corresponding to the movement area of the first lens group 51 has light transmittance, for example, the housing of the predetermined area may be hollowed out, and a transparent glass or a lens may be disposed. This can satisfy the continuous focusing of the periscopic camera module 5.

Based on the foregoing implementation, the working principle of focusing of the periscopic camera module of the electronic device according to the embodiment of the present application is specifically described below.

When the electronic device is in a folded state (i.e., the second section of the flexible screen 3 is hidden in the accommodating cavity), the second driving mechanism 4 and the periscopic camera module 5 are in a state shown in fig. 5; at this time, the periscopic camera module 5 can perform shooting interaction by using optical zooming with fixed magnification, wherein the position relationship of each lens group in the periscopic camera module 5 is shown in fig. 6; the corresponding light path is schematically shown in fig. 7.

When the electronic device is in the unfolded state (that is, the flexible screen 3 of the electronic device is unfolded to the maximum state, that is, the first section of the flexible screen 3 and the second section of the flexible screen 3 are both exposed outside), the states of the second driving mechanism 4 and the periscopic camera module 5 are as shown in fig. 8; the position relationship of each lens group inside the periscopic camera module 5 is shown in fig. 9; corresponding light path schematic diagram, as shown in fig. 10, at this moment, the space grow of the inside chamber that holds of electronic equipment provides periscopic camera module 5 and realizes the required space of bigger magnification, thereby second actuating mechanism 4 drive first lens group 51 moves (moves left in fig. 8) and prolongs the inside light path of periscopic camera module 5 promptly, realizes zooming of bigger magnification.

It should be noted that, since the photosensitive assembly 531 is located inside the second housing 2 during the process of unfolding the flexible screen 3, the photosensitive assembly 531 can be protected.

Here, above-mentioned implementation can realize the zooming of bigger multiplying power except basic multiplying power when electronic equipment is in the expanded state, and through the drive effect of second actuating mechanism, the multiplying power of zooming can be adjusted between basic multiplying power and maximum magnification moreover, can realize the continuous optics of many multiplying powers promptly and zoom and adjust, promote and zoom and shoot and experience.

Alternatively, when the second driving mechanism 4 is connected to the second barrel 55 and the electronic device is in the unfolded state, the second driving mechanism 4 drives the second lens group 52 and the third lens group 53 to move together, so as to adjust the distance between the first lens group 51, the second lens group 52 and the third lens group 53.

Here, since the second lens group 52 and the third lens group 53 are fixed in the second barrel 55, the second driving mechanism 4 is connected to the second barrel 55 to drive the second barrel 54 to move, that is, to drive the second lens group 52 and the third lens group 53 to move together.

Based on this, in order to realize that the second lens barrel 55 moves relative to the first lens barrel 54 under the driving action of the second driving mechanism 4, referring to fig. 11 and 14, as an alternative implementation manner, the first lens barrel 54 and the second driving mechanism 4 are fixed to the second housing 2, and the second housing 2 is provided with a first through hole 201, referring to fig. 12 and 15, the incident light enters the first lens group 51 through the first through hole 201 and the first opening 541;

here, the first lens barrel 54 and the second driving mechanism 4 are fixed to the second housing 2, which means that the position of the first lens group 51 is kept unchanged during zooming, the second driving mechanism 4 drives the second lens group 52 and the third lens group 53 to move during optical zooming, and during zooming with a larger magnification, the second driving mechanism 4 drives the second lens barrel 55 to move in the same direction as the flexible panel 3 which brings the electronic device into the unfolded state.

Since the first lens group 51 is fixed on the second housing 2 and the position remains unchanged during zooming, the light incident position of the incident light entering the first lens group 51 remains unchanged, and the first through hole 201 and the first opening 541 remain relatively fixed, where the first through hole may be a back-shooting opening of the electronic device.

Here, the second connecting member 10 is disposed on the side wall of the second barrel 55 adjacent to the second side wall, and referring to fig. 4, the second driving mechanism 4 is connected through the second connecting member 10 to drive the second barrel 55 to move.

When the electronic device is in a furled state (i.e., the second section of the flexible screen 3 is hidden in the accommodating cavity), the second driving mechanism 4 and the periscopic camera module 5 are in a state as shown in fig. 11, and at this time, the periscopic camera module 5 can perform shooting interaction by using optical zooming with a fixed magnification; the position relationship of each lens group inside the periscopic camera module 5 is shown in fig. 12; the corresponding light path is schematically shown in fig. 13.

When the electronic device is in the unfolded state (that is, the flexible screen 3 of the electronic device is unfolded to the maximum state, that is, the first section of the flexible screen 3 and the second section of the flexible screen 3 are both exposed outside), the states of the second driving mechanism 4 and the periscopic camera module 5 are as shown in fig. 14; the position relationship of each lens group inside the periscopic camera module 5 is shown in fig. 15; corresponding light path schematic diagram, as shown in fig. 16, at this moment, the space grow of the inside chamber that holds of electronic equipment provides periscopic camera module 5 and realizes the required space of bigger magnification, thereby second actuating mechanism 4 drive second lens group 52 and third lens group 53 move (move left in the figure) thereby prolong the inside light path of periscopic camera module 5 promptly, realize zooming of bigger magnification.

Since the first barrel 54 moves synchronously with the first housing 1, that is, the relative position of the first barrel 54 and the first housing 1 is not changed, that is, the second through hole and the first opening 541 are kept relatively fixed, here, the first through hole may be a back-shooting hole of the electronic device.
