The embodiment of the application provides a camera module, the camera module can be used for electronic equipment such as cell-phone, panel computer. Specifically, the camera module can be used for realizing a camera shooting function.
Referring to fig. 1, a schematic structural diagram of a camera module according to an embodiment of the present application is shown, and as shown in fig. 1, the camera module may specifically include: a lens 10, a photosensitive chip 11 and a driving component 12; the driving assembly 12 may include a first frame 121, a second frame 122, an elastic member 123, and a piezoelectric driving member 13, where the first frame 121 is sleeved outside the second frame 122 and forms a first gap with the second frame 122, one end of the elastic member 123 is connected with the first frame 121, and the other end of the elastic member 123 is connected with the second frame 122; the first frame 121 is fixedly connected with the lens 10, the second frame 122 is fixedly connected with the photosensitive chip 11, the piezoelectric driving piece 13 is connected to the elastic piece 123, and under the condition that the piezoelectric driving piece 13 is electrified, the piezoelectric driving piece 13 can be used for driving the elastic piece 123 to move so as to drive the second frame 122 and the photosensitive chip 11 to move through the elastic piece 123, and focusing and anti-shake functions are achieved.
In this embodiment of the present application, since the mass of the photosensitive chip 11 is relatively light, the dynamic performance is easily maintained in the process of driving the photosensitive chip 11 by the piezoelectric driving element 13, and the driving performance of the piezoelectric driving element 13 is relatively good. Moreover, the photosensitive chip 11 is driven to move by the driving component 12 and the piezoelectric driving piece 13 with smaller volume, so that the design of adopting a motor in the camera module is avoided, the volume of the camera module is easily reduced, and the weight of the camera module is reduced.
In particular, the lens 10 may be used to capture images. The light sensing chip 11 may be disposed opposite to the lens 10 to convert an optical signal entering from the lens 10 into an electrical signal carrying image information. The driving component 12 can be used for driving the photosensitive chip 11 to move so as to realize focusing and anti-shake functions.
Referring to fig. 2, a schematic structural diagram of a driving assembly according to an embodiment of the present application is shown, and referring to fig. 3, a schematic structural diagram of the driving assembly and the photosensitive chip according to an embodiment of the present application is shown. As shown in fig. 2, the elastic member 123 may specifically include a long side segment 1231 and a short side segment 1232 connected to each other, and the length of the long side segment 1231 is greater than the length of the short side segment 1232; one end of the long side segment 1231 is connected to the first frame 121, the other end of the long side segment 1231 is connected to one end of the short side segment 1232, and the other end of the short side segment 1232 is connected to the second frame 122; the piezoelectric driver 13 is connected to one end of the long side section 1231 connected to the first frame 121.
In practical application, because the length of the long side segment 1231 is longer, and the piezoelectric driving piece 13 is connected to the end of the long side segment 1231 near the first frame 121, when the piezoelectric driving piece 13 drives the long side segment 1231 to deform, the deformation generated by the piezoelectric driving piece 13 can be amplified as much as possible, so as to drive the second frame 122 and the photosensitive chip 11 to generate larger displacement, so as to improve focusing and anti-shake displacement that can be realized by the photosensitive chip 11.
Alternatively, the first frame 121 and the second frame 122 are rectangular frames; the long side section 1231 is disposed between the side of the first frame 121 and the side of the second frame 122, and is parallel to the side of the first frame 121 and the side of the second frame 122; short side segment 1232 is perpendicular to long side segment 1231. That is, the long side segment 1231 and the short side segment 1232 may be disposed in an "L" shape to further amplify the deformation generated by the piezoelectric driving part 13, and to improve the focusing and anti-shake displacement that can be achieved by the photosensitive chip 11.
In practical applications, the first frame 121 and the second frame 122 may be rectangular frames, and the shape of the first frame 121 is similar to that of the second frame 122, so that the first gap between the first frame 121 and the second frame 122 is uniform when the first frame 121 is sleeved outside the second frame 122. Because the long side section 1231 and the short side section 1232 are perpendicular, the length of the long side section 1231 can be as long as possible, and thus, the deformation generated by the piezoelectric driving piece 13 can be amplified as much as possible by the long side section 1231, and the focusing and anti-shake displacement that can be realized by the photosensitive chip 11 can be improved.
It should be noted that, in practical applications, the included angle between the long side segment 1231 and the short side segment 1232 may also be other values. For example, the included angle between the long side segment 1231 and the short side segment 1232 may be 70 degrees, 85 degrees, 98 degrees, or the like, and the included angle between the long side segment 1231 and the short side segment 1232 in the embodiment of the present application is not specifically limited.
In some alternative embodiments of the present application, the long side segment 1231 has a second gap with the first frame 121 and the second frame 122, so as to provide enough space for the elastic member 123, the second frame 122, and the displacement of the photosensitive chip 11.
In practical applications, the second gap between the long side segment 1231 and the first frame 121 and the second frame 122 may be set according to practical situations. Alternatively, the width of the second gap may be less than or equal to 1 mm, so that the movement of the elastic member 123, the second frame 122, and the photosensitive chip 11 may have enough space, and the overall volume of the driving assembly 12 may be small.
By way of example, the second gap between the long side segment 1231 and the first frame 121 and the second frame 122 may be 0.6 mm, 0.85 mm, 1 mm, or the like, and the second gap width between the long side segment 1231 and the first frame 121 and the second frame 122 is not specifically limited in the embodiments of the present application.
Referring to fig. 4, which illustrates a schematic partial structure of a camera module according to an embodiment of the present application, as shown in fig. 4, the elastic member 123 may include a first side and a second side disposed away from each other, where the first side is adjacent to the first frame 121, and the second side is adjacent to the second frame 122; the number of piezo drives 13 is two, one piezo drive 13 being arranged on the first side and the other piezo drive 13 being arranged on the second side. In a specific application, by arranging one piezoelectric driving piece 13 on each of the first side and the second side of the elastic piece 123, the deformation of the two piezoelectric driving pieces 13 can be overlapped to generate larger deformation and driving force, and the amplification effect of the long side section 1231 can enable the photosensitive chip 11 to realize larger anti-shake displacement, so that the anti-shake effect of the camera module is improved.
For example, in the case where two piezoelectric drivers 13 on both sides of the elastic member 123 are simultaneously supplied with opposite voltages, one piezoelectric driver 13 is compressed in a direction away from the elastic member 123, and the other piezoelectric driver 13 is compressed in a direction toward the elastic member 123, the deformations of the two piezoelectric drivers 13 may be superimposed to generate a larger deformation and driving force.
As shown in fig. 4, the piezoelectric driver 13 may specifically include: a first electrode sheet 131, a piezoelectric sheet 132, and a second electrode sheet 133, which are sequentially disposed; wherein the first electrode tab 131 is connected to the elastic member 123. Under the condition that the first electrode piece 131 and the second electrode piece 133 are electrified, the piezoelectric piece 132 can deform, so that the elastic piece 123 is driven to move, and the second frame 122 and the photosensitive chip 11 are driven to move.
Referring to fig. 5, a schematic partial structure of an elastic member according to an embodiment of the present application is shown, and as shown in fig. 5, an electrical connector 124 is disposed on a side of the elastic member 123, which is close to the photosensitive chip 11, and the electrical connector 124 is electrically connected to the photosensitive chip 11, so as to guide out an electrical signal of the photosensitive chip 11.
Illustratively, the electrical connector 124 may specifically include copper wires, a spring sheet, or a conductive coating, and the embodiment of the present application is not limited to the specific content of the electrical connector 124.
Optionally, the elastic member 123 is a spring wire, and since the spring wire has good flexibility and elasticity (the extension length can reach 3-4 times of the original spring wire length), the anti-shake displacement of the photosensitive chip 11 can be further improved when the elastic member 123 is a spring wire, thereby improving the anti-shake effect of the camera module.
In practical application, the elastic member 123 may be a spring, etc., and the specific content of the elastic member in the embodiment of the present application may not be limited.
Optionally, the camera module may further include a bracket, where the first frame 121 and the lens 10 are fixedly connected to the bracket. The holder may be used to support the first housing 121 and the lens 10. In practical applications, the bracket, the first frame 121 may be used as a stator of the driving assembly 12, and the second frame 122 and the photosensitive chip 11 may be used as a rotor of the driving assembly 12.
In summary, the camera module according to the embodiments of the present application may at least include the following advantages:

Because the photosensitive chip is lighter in weight, the dynamic performance is easy to maintain in the process that the piezoelectric driving piece drives the photosensitive chip to move, and the driving performance of the piezoelectric driving piece is better. Moreover, the photosensitive chip is driven to move through the driving component with smaller volume and the piezoelectric driving piece, so that the design of adopting a motor in the camera module is avoided, the volume of the camera module is easily reduced, and the weight of the camera module is reduced.
