The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, an electronic device according to an embodiment of the present invention includes a module housing 100, a photo sensor chip 200, a reflector 300 and a plurality of lens sets 400.

Wherein, module casing 100 is the main peripheral component of the module of making a video recording, and a plurality of lens group 400 set up in module casing 100, and is specific, and the material of module casing 100 is light-tight material, and then guarantees that ambient light only gets into in the module casing 100 from lens group 400. Specifically, the plurality of lens groups 400 are disposed on the module housing 100 at intervals, so as to avoid undesirable optical effects between the lens groups.

Sensitization chip 200 is the formation of image part of the module of making a video recording, and sensitization chip 200 can be the signal of telecommunication with light signal conversion, then reaches the purpose of formation of image, and sensitization chip 200 sets up within module casing 100, because module casing 100 is opaque, and then can guarantee that the received light signal of sensitization chip 200 is the ambient light who jets into for organizing 400 through the lens.

The reflector 300 is a functional device that reflects ambient light, and in this embodiment, the reflector 300 has a plurality of working positions, the working positions are one-to-one corresponding to the lens sets 400, and the reflector 300 is movably disposed in the module housing 100, and the reflector 300 can be switched between the working positions, and further is in a relative state with the corresponding lens sets 400 at the working positions, so as to reflect ambient light penetrating the corresponding lens sets 400 to the photo sensor chip 200.

Specifically, the optical parameters of the lens groups 400 may be different, and the reflector 300 may work at a plurality of positions, so as to realize the photosensitive shooting of the photosensitive chip 200 under the conditions of different optical parameters.

The disclosed module of making a video recording of this embodiment, with the movably setting of reflector 300 in module casing 100, set up a plurality of lens groups 400 simultaneously on module casing 100 at the interval, and then make reflector 300 can remove the position relative with each lens group 400 in module casing 100, under this condition, when ambient light sees through lens group 400, reflector 300 can remove the position relative with this lens group 400, and then reflect ambient light to photosensitive chip 200, and then accomplish the formation of image. Under this condition, need not set up corresponding sensitization chip 200 for every lens group 400 again when setting up a plurality of lens groups 400, but realize a sensitization chip 200 of a plurality of lens groups 400 sharing through reflector 300, it is thus clear that electronic equipment need not to dispose more photosensitive chip 200, can also share partial structure simultaneously, and then can reduce the quantity of component, finally can reduce the occupation space of the module of making a video recording.

Moreover, compared to the case where a plurality of cameras are disposed in the electronic device according to the related art, the embodiment of the present application can reduce the number of photosensitive chips 200, and also reduce excessive circuit connections and intermediate devices related to the circuit connections, such as board-to-board connectors, while reducing the number of photosensitive chips 200, thereby reducing interference between the intermediate devices and avoiding reliability problems due to a large number of intermediate devices.

In order to improve the shooting quality of the camera module and make the picture shot by the camera module clearer, in an optional scheme, the camera module disclosed in the embodiment of the present application may include a focusing lens 410 and a first driving mechanism 500. The focusing lens 410 may be disposed between the reflector 300 and the photosensitive chip 200, in which case the focusing lens 410 covers the photosensitive chip 200 such that the ambient light reflected from the reflector 300 passes through the focusing lens 410 before reaching the photosensitive chip 200, and the ambient light may be processed by the focusing lens 410. The focusing lens 410 is connected to the first driving mechanism 500, and the first driving mechanism 500 drives the focusing lens 410 to move in a direction close to the photosensitive chip 200 or away from the photosensitive chip 200, that is, when shooting objects at different distances, the focusing lens 410 and the first driving mechanism 500 cooperate to complete focusing.

In the embodiment of the present application, the first driving mechanism 500 may include a shape memory alloy member or a lead screw driving mechanism, and specifically, the shape memory alloy member or the lead screw driving mechanism may be disposed on the module housing 100 and connected to the focusing lens 410. Taking the shape memory alloy as an example, the shape memory alloy will deform after being electrified, and then the focusing lens 410 can be driven to move, so as to achieve the purpose of driving. Of course, the first driving mechanism 500 may be of other types, such as a hydraulic telescopic member, a pneumatic telescopic member, etc., and the embodiment of the present application does not limit the specific type of the first driving mechanism 500.

In a specific operation process, when a long-range view is shot, the first driving mechanism 500 drives the focusing lens 410 connected with the first driving mechanism to move towards the direction close to the photosensitive chip 200, so that the imaging can still be clear even if the shot object is far away. Similarly, when the shooting object is close to the object, the first driving mechanism drives the focusing lens 410 to move in the direction away from the photosensitive chip 200, so that the situations of virtual focus, blurred image and the like cannot occur under the close-range shooting situation.

As described above, the reflector 300 can be switched between a plurality of working positions to reflect the corresponding ambient light passing through the lens assembly 400 to the photo chip 200, thereby completing the imaging. Specifically, the movement of the reflecting member 300 may be achieved by manual manipulation. In order to facilitate the use of the user, in a further technical solution, the camera module disclosed in the embodiment of the present application may further include a second driving mechanism 600, the second driving mechanism 600 is connected to the reflective element 300, and the second driving mechanism 600 drives the reflective element 300 to switch between a plurality of working positions. Under this condition, second actuating mechanism 600 drive reflection piece 300 removes, and it is more convenient to adjust for the module of making a video recording is more intelligent.

Further, the structure of the second driving mechanism 600 may be various, for example, the second driving mechanism 600 may be a hydraulic expansion member, a pneumatic expansion member, or the like.

Of course, the second driving mechanism 600 may be other driving mechanisms, and in an alternative, the second driving mechanism 600 may include a base 610, a gear mechanism 620 and a first driving motor 630. The base 610 includes a rack 611, the rack 611 is connected to the reflecting member 300, the first driving motor 630 is drivingly connected to the rack 611 through the gear mechanism 620, and the reflecting member 300 is movable along with the rack 611. In a specific working process, since the gear mechanism 620 is meshed with the rack 611, when the first driving motor 630 drives the gear mechanism 620 to rotate, the gear mechanism 620 can drive the rack 611 to move, so that the rack 611 drives the reflecting member 300 to move. For example, when the first driving motor 630 rotates clockwise, the first driving motor 630 drives the gear mechanism 620 to rotate, so as to drive the rack 611 to move towards the first direction, and further to realize that the reflecting member 300 moves towards the first direction; when the first driving motor 630 rotates counterclockwise, the first driving motor 630 drives the gear mechanism 620 to rotate, so as to drive the rack 611 to move in the second direction, and further, the reflecting member 300 moves in the second direction, where the first direction is opposite to the second direction. Since the gear mechanism 620 has an advantage of high accuracy in engagement with the rack gear 611, the first driving motor 630 enables the reflecting member 300 to move with higher accuracy by engagement of the gear mechanism 620 with the rack gear 611.

In a further aspect, in order to optimize the second driving mechanism 600, so that the reflecting member 300 can move to the position opposite to the lens assembly 400 in the working state more stably under the cooperation thereof, and thus complete the image formation, in an alternative aspect, the gear mechanism 620 may include a first gear 621 and a second gear 622, and the first gear 621 and the second gear 622 are spaced apart and are both engaged with the rack 611. In this case, during the operation of the second driving mechanism 600, the first gear 621 and the second gear 622 rotate in the same direction, thereby performing a cooperative driving function, and thus achieving a more stable driving.

As described above, the reflector 300 reflects the ambient light passing through the lens assembly 400 to the photosensitive chip 200, thereby implementing imaging. In the actual operation process, when light passes through two different media through the reflective member 300, two phenomena, i.e., reflection and refraction, occur, a part of light is reflected to the photosensitive chip 200 through the reflective member 300, and a part of light is also refracted through the reflective member 300, which causes light loss, which results in blurred images on the photosensitive chip 200. Based on this situation, in an alternative embodiment, the reflector 300 may be a total reflection prism, in which case, when the ambient light enters the total reflection prism, the ambient light will be emitted in the opposite direction to the incident direction, so that the light energy loss is reduced, the image is clearer, and the shooting quality is higher.

In a further aspect, in order to set up the plurality of lens groups 400 and still keep the camera module occupying less stacking space of the electronic device, in an optional aspect, the plurality of lens groups 400 are arranged in parallel, and the optical axis direction of the lens groups 400 is perpendicular to the optical axis direction of the photosensitive chip 200. The arrangement mode is favorable for forming a periscopic structure and is more favorable for being arranged in electronic equipment with a small thickness. The plurality of lens groups 400 are disposed in a row in a direction close to the photosensitive chip 200. The arrangement is simple, and the working positions of the reflecting member 300 are aligned, so that the movement of the reflecting member 300 is simpler and the driving is more convenient.

Meanwhile, a plurality of lens group 400 are in the direction of being close to photosensitive chip 200 and are arranged in a row for a plurality of lens group 400 are all inequality apart from photosensitive chip 200's distance, under the condition of the unmovable focusing lens piece 410, only drive reflector 300 and remove and just can realize the function of zooming, and this can further improve the zoom capability of the module of making a video recording undoubtedly.

On this basis, the module of making a video recording still includes focusing lens piece 410, focusing lens piece 410 with be the further cooperation of a plurality of lens groups 400 of one row setting, can further improve the zoom ability of the module of making a video recording.

Of course, in the camera module disclosed in the embodiment of the present application, the plurality of lens groups 400 may also adopt various other distribution modes, for example, the plurality of lens groups 400 may be distributed along the edge of the circular arc. As long as the reflector 300 can ensure that the ambient light passing through the lens assembly 400 is reflected to the photosensitive chip 200.

As described above, the optical parameters of the lens groups 400 may be different, which can meet the shooting requirements of different environments, and in order to avoid the interference of stray light during shooting and make the imaging of the photosensitive chip 200 more clear, in an optional scheme, the camera module may further include the shielding member 700 and the third driving mechanism. The shielding member 700 includes a light-transmitting region and a light-shielding region connected to the light-transmitting region, wherein the light-shielding region is made of a completely opaque material, so that stray light can be effectively prevented from passing through, and adverse effects on imaging can be further caused, and the light-transmitting region can be formed by a light-transmitting through hole or a light-transmitting material, so that it is ensured that ambient light incident from the lens assembly 400 passes through, and thus, the imaging clarity can be ensured. The shielding member 700 is movably disposed in the module housing, specifically, the shielding member 700 is disposed between the plurality of lens groups 400 and the reflector 300, the third driving mechanism drives the shielding member 700 to move, so as to drive the light-transmitting area to move along with the reflector 300, the light-transmitting area is opposite to the reflector 300, and the inner side ports of the lens groups 400 distributed in a staggered manner with respect to the reflector 300 are covered with a light-shielding area. In this case, when the ambient light passes through the lens assembly 400, in order to ensure no interference of other stray light, the third driving mechanism drives the shielding member 700 to move, so that the light-transmitting area is opposite to the lens assembly 400, and the light-shielding area is opposite to the other lens assemblies 400, so as to ensure that the reflector 300 only reflects the ambient light passing through the lens assembly 400 to the sensor chip, and further, the lens assembly 400 with different optical parameters is used without being interfered by the ambient light from the other lens assemblies 400.

The third driving mechanism may be various, for example, the third driving mechanism may be a telescopic mechanism, and the third driving mechanism may drive the shutter 700 to move, so as to move the light-transmitting area and the light-shielding area. The shield 700 may be a rigid plate-like structure.

In order to further reduce the occupied space, in an alternative, the third driving mechanism may include a first winding mechanism 801 and a second winding mechanism 802, and the shielding member 700 is a flexible film with good flexibility and capable of being curled and bent. One end of the shade 700 is wound around the first winding mechanism 801 and the other end of the shade 700 is wound around the second winding mechanism 802, the first winding mechanism 801 and the second winding mechanism 802 driving the movement of the shade 700. In a specific operation, when a certain lens assembly 400 is used, the first winding mechanism 801 and the second winding mechanism 802 rotate simultaneously in the same direction, so as to drive the blocking member 700 to move, such that the transparent area moves to the area opposite to the lens assembly 400, and the other lens assemblies 400 are blocked by the light-blocking area.

The types of the first winding mechanism 801 and the second winding mechanism 802 may be various, as long as the mechanism for winding and unwinding the flexible film can be implemented, and further, in order to make the movement of the shade 700 driven by the first winding mechanism 801 and the second winding mechanism 802 smoother and more accurate, in an alternative scheme, the first winding mechanism 801 and the second winding mechanism 802 may each include a second driving motor 810, a third gear 820 and a gear sleeve 830. The power output shaft of the second driving motor 810 is connected to the third gear 820, the third gear 820 is disposed inside the gear sleeve 830 and engaged with the gear sleeve 830, and the shutter 700 is wound around the gear sleeve 830. In a specific working process, the power output shaft of the second driving motor 810 drives the third gear 820 to rotate, and the third gear 820 is meshed with the gear sleeve 830, so that the third gear 820 drives the gear sleeve 830 to rotate, the shielding piece 700 is retracted and released, the shielding piece 700 moves under the matching of the first winding mechanism 801 and the second winding mechanism 802, and the light transmission area moves.

In order to reduce the space of the electronic device occupied by the camera module, in an alternative scheme, the second driving motor 810 may be disposed inside the gear sleeve 830, in which case, the second driving motor 810 does not need to separately occupy additional space, but directly utilizes the space inside the gear sleeve 830, and this assembly manner can make the structures of the first winding mechanism 801 and the second winding mechanism 802 more compact and occupy less space. In this case, the module case 100 is provided with a mounting seat 900, and a portion of the mounting seat 900 extends into the gear sleeve 830 and is fixedly connected to the second driving motor 810, thereby implementing the mounting of the second driving motor 810.
