fig. 3 shows the structure of the camera module in the second photographing state, in which the second reflecting mirror 12 faces the lens assembly 20, and the light from the other side of the first direction M is reflected from the second reflecting mirror 12 and then reaches the photosensitive element 30 through the lens assembly 20 along the first direction M, that is, the light is reflected by the second reflecting mirror 12 along the direction of arrow B shown in fig. 3 and then travels toward the lens assembly 20.
Compared with the prior art, in the camera module according to the first embodiment of the present invention, the reflection assembly 10 is disposed on the light incident side of the lens assembly 20, and the first reflection mirror 11 and the second reflection mirror 12 of the reflection assembly 10 can be switched between the first shooting state and the second shooting state under the driving of the driving device. In the first image capturing state, light from one side of the first direction M is reflected by the first mirror 11 and then reaches the photosensitive element 30 through the lens assembly 20 along the first direction M; in the second imaging state, the light beam from the other side of the first direction M is reflected from the second reflecting mirror 12 and reaches the photosensitive element 30 in the first direction M. Like this, can be located the light reflection of the different sides of first direction M to camera lens subassembly 20 through reflection subassembly 10, and then reach photosensitive element 30 through camera lens subassembly 20, thereby make the camera module when taking the image that is located the different sides of first direction M, can use the same camera lens subassembly 20 and photosensitive element 30, just also make the shooting ability of this camera module when taking the image that is located the different sides of first direction M keep unanimous, and need not to adopt two different camera modules, thereby can avoid the unbalanced problem of shooting ability of different camera modules when practicing thrift the cost.
Meanwhile, compared with the situation that two independent camera modules are simultaneously configured in the electronic equipment, the camera module in the first embodiment of the invention can save the internal space of the electronic equipment.
It should be noted that, the forms of the lens assembly 20 and the photosensitive element 30 are not limited herein, the lens assembly 20 may implement focusing during shooting, an anti-shake lens may implement an optical anti-shake function, or a plurality of lenses may be used to implement optical zooming, the photosensitive element 30 may be a photosensitive chip, and the photosensitive chip may convert incident light into an electrical signal and convert the electrical signal into an image signal.
In addition, the preset included angle α may be any angle within a range greater than 0 degrees and less than 180 degrees, and the included angle between the first reflecting mirror 11 and the second reflecting mirror 12 is defined as an angle between the non-reflective surface of the first reflecting mirror 11 and the non-reflective surface of the second reflecting mirror 12, and the first reflecting mirror 11 and the second reflecting mirror 12 arranged at the preset included angle α may implement reflection of two opposite light rays to the same direction after changing positions, and the description may be made from two examples thereof.
In one example, the predetermined included angle α between the first reflecting mirror 11 and the second reflecting mirror 12 may be 45 degrees, and in the first photographing state, the first reflecting mirror 11 faces the lens assembly 20, and at this time, the light from one side of the first direction M (the left side of the camera module shown in fig. 2) is reflected by the first reflecting mirror 11 and then travels along the first direction M, so as to reach the photosensitive element 30 through the lens assembly 20. The second reflector 12 is parallel to the first direction M, and light from the other side of the first direction M (the right side of the camera module shown in fig. 2) is reflected by the second reflector 12 and then propagates along the original path. Similarly, in the second photographing state, the second reflecting mirror 12 faces the lens assembly 20 after the position is changed, and at this time, the light from the right side of the camera module shown in fig. 3 is reflected by the second reflecting mirror 12 and then travels in the first direction M, so as to reach the photosensitive element 30 through the lens assembly 20. The first reflector 11 is parallel to the first direction M after changing the position, and the light from the left side of the camera module shown in fig. 3 is reflected by the first reflector 11 and then propagates along the original path.
In another example, the predetermined included angle α between the first reflecting mirror 11 and the second reflecting mirror 12 may be 90 degrees, and in the first photographing state, the first reflecting mirror 11 faces the lens assembly 20, and at this time, the light from one side of the first direction M (the left side of the camera module shown in fig. 2) is reflected by the first reflecting mirror 11 and then travels along the first direction M, so as to reach the photosensitive element 30 through the lens assembly 20. The second reflector 12 is offset from the lens assembly 20, and light from the other side of the first direction M (the right side of the camera module shown in fig. 2) is reflected by the second reflector 12 and then propagates along the first direction M, but the propagation path of the light is offset from the position of the lens assembly 20. Similarly, in the second photographing state, the second reflecting mirror 12 faces the lens assembly 20 after the position is changed, and at this time, the light from the right side of the camera module shown in fig. 3 is reflected by the second reflecting mirror 12 and then travels in the first direction M, so as to reach the photosensitive element 30 through the lens assembly 20. The first reflector 11 is staggered with the lens assembly 20 after the position is changed, and light from the left side of the camera module shown in fig. 3 is reflected by the first reflector 11 and then propagates along the first direction M, but the propagation path is staggered with the position of the lens assembly 20.
The first reflector 11 and the second reflector 12 used herein may be two independent reflectors (shown in fig. 4) or may be a reflector of an integrated structure (shown in fig. 5). Meanwhile, a mirror can be used for realizing the conversion between the first photographing state and the second photographing state, that is, after one mirror is rotated by 90 degrees, light from the opposite direction is reflected to the lens assembly 20 along the first direction M, and compared with the case of using one mirror, the first mirror 11 and the second mirror 12 arranged at the preset included angle α can not only reduce the rotation angle of the mirror, but also reduce the space size required when the mirror is rotated, for example, when the preset included angle α of the first mirror 11 and the second mirror 12 is 45 degrees, only any point on the bisector of the included angle between the first mirror 11 and the second mirror 12 needs to be rotated by 22.5 degrees, so that the conversion between the first photographing state and the second photographing state of the first mirror 11 and the second mirror 12 can be realized, and compared with the case of rotating one mirror by 90 degrees, the space size required when the first mirror 11 and the second mirror 12 are controlled to move can be obviously reduced, thereby reducing the size of the camera module.
The position change of the first reflecting mirror 11 and the second reflecting mirror 12 is controlled by a driving device, the driving device is used as a power source, and the driving device can be selected according to the movement mode of the first reflecting mirror 11 and the second reflecting mirror 12, for example, when the first reflecting mirror 11 and the second reflecting mirror 12 change the position by rotating, the driving device can adopt a motor or a motor to control the movement of the first reflecting mirror 11 and the second reflecting mirror 12, and when the first reflecting mirror 11 and the second reflecting mirror 12 change the position by translating, the driving device can adopt an electric push rod or a lead screw nut mechanism to control the movement of the first reflecting mirror 11 and the second reflecting mirror 12.
In a specific embodiment, the reflection assembly 10 may implement the position change of the first reflection mirror 11 and the second reflection mirror 12 by rotating, as shown in fig. 6, the reflection assembly 10 may include a base 13 and a first bracket 14, the first bracket 14 is connected to the base 13 and can rotate on the base 13 around a second direction N perpendicular to the first direction M, the first reflection mirror 11 and the second reflection mirror 12 are respectively disposed parallel to the second direction N, the first reflection mirror 11 and the second reflection mirror 12 are respectively connected to the first bracket 14, and the first reflection mirror 11 and the second reflection mirror 12 are driven by the first bracket 14 to rotate so that the first reflection mirror 11 or the second reflection mirror 12 faces the lens assembly 20. In this way, the first reflecting mirror 11 and the second reflecting mirror 12 can be adjusted in position during the rotation of the first carriage 14, thereby achieving the change between the first imaging state and the second imaging state.
Specifically, as shown in fig. 7 and 8, the base 13 includes a bottom plate 131, and two side plates 132 oppositely disposed on the bottom plate 131 along the second direction N, and the first brackets 14 are respectively rotatably connected with the two side plates 132 to rotate around the second direction N between the two side plates 132. Thus, the two side plates 132 provide a foundation for the pivotal connection of the first bracket 14, and the bottom plate 131 connects the two side plates 132 to form a single body.
It should be noted that the base 13 and the first support 14 may have various forms, and when the first reflector 11 and the second reflector 12 adopt different driving manners, the base 13 and the first support 14 may adopt different forms, the base 13 may provide a connection basis for other components of the reflection assembly 10, and the first support 14 may provide a connection basis for the first reflector 11 and the second reflector 12, so that the first reflector 11 and the second reflector 12 can move relative to the base 13.
Preferably, the base 13 may be connected to the first bracket 14 by driving the ultrasonic motor 15, the ultrasonic motor 15 is disposed on one side of one of the side plates 132 of the base 13 close to the first bracket 14, and the ultrasonic motor 15 is configured by attaching a piezoelectric ceramic plate to a stator metal plate, and using a piezoelectric effect of the piezoelectric ceramic plate under an alternating voltage, each mass point on the stator metal plate generates clockwise or counterclockwise fluctuation. The first holder 14 is provided with a rotor metal piece 151 (shown in fig. 9) in close contact with the stator metal piece of the ultrasonic motor 15 at a corresponding position, and the rotor metal piece 151 on the first holder 14 is rotated by the kinetic friction force of the ultrasonic motor 15. Meanwhile, as shown in fig. 9, one side (right side in fig. 9) of the first bracket 14 is provided with a protruding cylindrical protrusion 144, and the cylindrical protrusion 144 and the cylindrical groove 133 at the corresponding position of the other side plate 132 (right side plate 132 in fig. 7) of the base 13 are engaged with each other to form a rotation center shaft of the first bracket 14, while a ball 145 may be provided therebetween to facilitate the rotation of the first bracket 14.
In addition, the base 13 can be provided with an FPC134, and the circuit arranged on the FPC134 is communicated with the ultrasonic motor 15 on the base 13 and an external circuit to carry out electrification and motion control of the ultrasonic motor 15, wherein the FPC134 is of a soft structure, so that the motion of the ultrasonic motor 15 is not influenced.
It should be noted that, the position-limiting fixing manner of the first bracket 14 here can be realized by static friction force of the rotor metal sheet 151 on the first bracket 14 and the stator metal sheet of the ultrasonic motor 15 under the pre-pressure, that is, after the first bracket 14 moves to the predetermined position, the ultrasonic motor 15 stops vibrating and no kinetic friction force is provided for the rotor metal sheet 151 of the first bracket 14. At this time, a large static friction force is generated between the stator metal piece of the ultrasonic motor 15 and the rotor metal piece 151 on the first holder 14 by the pre-pressure between the first holder 14 and the two side plates 132 of the base 13, and the first holder 14 is held at a predetermined position. The advantage of this fixing method is that it is no longer necessary to provide power to maintain the direction selection of the incident light by the first reflector 11 and the second reflector 12 during the shooting process of the camera module, and the power consumption of the camera module can be reduced.
Meanwhile, in other possible embodiments, an electromagnetic adsorption structure may also be selected to realize the limit fixation of the first bracket 14, for example, an electromagnetic coil is disposed on one of the side walls of the base 13, a magnetic conductive metal is disposed at a position where the first bracket 14 needs to be limited, when the first bracket 14 rotates to a predetermined position on the base 13, the electromagnetic coil on the base 13 is energized to generate a magnetic field, and the magnetic conductive metal on the first bracket 14 is adsorbed, thereby fixing the first bracket 14. Or, an electromagnetic coil is arranged on one side wall of the base 13, a magnet is arranged in the center of the electromagnetic coil, a magnetic conductive metal is arranged at a position of the first support 14, which needs to be limited, and when the first support 14 rotates to a preset position on the base 13, the magnet adsorbs the magnetic conductive metal, so that the first support 14 is fixed; when the first support 14 needs to rotate, the electromagnetic coil on the base 13 is energized to generate a magnetic field opposite to the magnet, so as to counteract the adsorption force of the magnet on the magnetic conductive metal, and the first support 14 can rotate on the base 13.
In addition, in order to limit the position of the first bracket 14 on the base 13 when the first bracket 14 rotates to a predetermined position, two limiting portions 135 (shown in fig. 6 to 8) may be disposed at intervals on one side of at least one of the two side plates 132 of the base 13, which is close to the other side plate 132, each limiting portion 135 extends from the surface of the side plate 132 to the direction close to the other side plate 132, and the outer edge of the first bracket 14 may rotate between the two limiting portions 135; when the outer edge of the first bracket 14 rotates to one of the limiting portions 135, the first reflecting mirror 11 faces the lens assembly 20, and when the outer edge of the first bracket 14 rotates to the other limiting portion 135, the second reflecting mirror 12 faces the lens assembly 20. In this way, the two limiting portions 135 on the side plate 132 of the base 13 can limit the rotation position of the first bracket 14, and the two limiting positions of the first bracket 14 correspond to the image capturing states of the first reflector 11 and the second reflector 12, so that the first reflector 11 and the second reflector 12 can be conveniently adjusted, and the light rays in different directions can reach the lens assembly 20 after being reflected by the corresponding reflectors and finally reach the photosensitive element 30. Fig. 6 shows the state of the first bracket 14 at one of the limit positions, and in fig. 6, it can be seen that the outer edge of the first bracket 14 abuts against the limit portion 135, and the reflector at the central position of fig. 6 keeps an angle of 45 degrees with the height direction of the base 13, so that the light rays propagating along the width direction of the base 13 (the direction is perpendicular to the second direction N) can be reflected to propagate along the height direction of the base 13 to reach the lens assembly 20, thereby realizing shooting.
