The lens assembly according to an embodiment of the present invention is described below with reference to fig. 1 to 6.

For example, as shown in fig. 1 and 4, a lens assembly according to an embodiment of the present invention includes a main body 100, a lens module 200, and an actuator assembly 300, wherein a receiving cavity is disposed inside the main body 100; the lens module 200 is mounted in the receiving cavity of the body part 100; the actuator assembly 300 is disposed at the top or bottom of the lens module 200; the actuator assembly 300 includes a memory alloy wire 310 and an actuator body; the memory alloy wire 310 is arranged along the optical axis S direction of the lens module 200 and can be electrically contracted; the actuating body comprises a first connecting rod 320 and a second connecting rod 330 which are connected with each other; the other end of the first link 320 is connected to the main body 100, and the other end of the second link 330 is connected to the lens module 200; the ends of the memory alloy wire 310 are connected to the junction of the first link 320 and the second link 330.

For example, as shown in fig. 2, the main body 100 includes an upper housing 110 and a base 120, a receiving cavity is formed between the upper housing 110 and the base 120, and the lens module 200 is located in the receiving cavity of the main body 100. Of course, the main body 100 may be integrally molded without providing the upper case 110 and the base 120. The actuator assembly 300 includes a memory alloy wire 310 and an actuator body, the actuator body includes a first link 320 and a second link 330 respectively located at both sides of the memory alloy wire 310, the first link 320 is connected with the main body 100 and the memory alloy wire 310, the second link 330 is connected with the lens module 200 and the memory alloy wire 310, and a straight line formed between a connection of the first link 320 and the main body 100 and a connection of the second link 330 and the lens module 200 is perpendicular to the optical axis S. And a certain included angle is formed between the first and second connecting rods 320 and 330 and the memory alloy wire 310, and the actuator assembly 300 can drive the first and second connecting rods 320 and 330 to rotate to move the lens module 200 by contracting the memory alloy wire 310, thereby playing a role of anti-shake.

Because the first and second links 320 and 330 have a certain angle with the memory alloy wire 310, and the memory alloy wire 310 is disposed along the optical axis S, when the memory alloy wire 310 has a certain amount of expansion and contraction in the optical axis S, the driving stroke of the first and second links 320 and 330 in the horizontal direction is greater than the amount of expansion and contraction of the memory alloy wire 310. It is easy to understand that, because the memory alloy wire 310 and the first link 320 have a certain angle, the relationship between the first link 320 and the memory alloy wire 310 can be regarded as a structure that is approximately triangular, such as shown in fig. 5. In the triangle formed by the first link 320 and the memory alloy wire 310, the length of the first link 320 may be regarded as constant, and when the memory alloy wire 310 contracts, the included angle between the first link 320 and the memory alloy wire 310 becomes large, so that the linear distance between the point where the first link 320 is connected with the main body 100 and the memory alloy wire 310 becomes large. It is easy to understand that, when the memory alloy wire 310 contracts by the same amount, the smaller the included angle between the first link 320 and the memory alloy wire 310, the greater the distance moved by the first link 320.

Similarly, the second link 330 is in a relationship with the memory alloy wire 310, and since the first link 320 and the second link 330 are disposed at both sides of the memory alloy wire 310, the first link 320 is fixedly connected to the main body portion 100, and the second link 330 is fixedly connected to the lens module 200, when the first link 320 and the second link 330 move in opposite directions while the main body portion 100 remains stationary, the lens module 200 moves a greater distance with respect to the main body portion 100, thereby achieving a greater driving stroke. Through such setting, make the length of memory alloy wire 310 need not the overlength can reach great drive stroke, play the effect of camera lens anti-shake, thereby do benefit to the miniaturization of camera lens subassembly volume.

In some embodiments of the present invention, the actuator assembly 300 includes two actuating bodies symmetrically disposed at both ends of the memory alloy wire 310 with respect to the memory alloy wire 310.

As shown in fig. 4 and 5, for example, the actuator assembly 300 includes two actuating bodies symmetrically disposed at both ends of the memory alloy wire 310 with respect to the memory alloy wire 310. The two first connecting rods 320 are located on the same side of the memory alloy wire 310 and are respectively disposed at two ends of the memory alloy wire 310, and the two second connecting rods 330 are located on the other side of the memory alloy wire 310 and are respectively disposed at two ends of the memory alloy wire 310.

The second connecting rods 330 are located on the same side of the memory alloy wire 310 and are fixedly connected to the lens module 200, so that when the memory alloy wire 310 is contracted, the two second connecting rods 330 can drive the lens module 200 in the same direction, and the effect that the two second connecting rods 330 drive the lens module 200 in opposite directions and cannot drive the lens module 200 to move is avoided. The first link 320 and the memory alloy wire 310 are arranged in the same manner.

For example, as shown in fig. 5, the two first links 320 located on the same side of the memory alloy wire 310 have the same length and the same included angle with the memory alloy wire 310, so that the two first links 320 move in the same direction and the same distance when the memory alloy wire 310 extends and contracts, and the lens module 200 and the main body 100 can be driven to move in the horizontal direction without relative rotation. The arrangement of the second link 330 on the first link 320 is the same.

In some embodiments of the present invention, the actuating body is integrally formed.

For example, as shown in fig. 5, the actuating body at the same end of the memory alloy wire 310 is integrally formed, so that the actuating body is easy to process and more convenient to manufacture and assemble.

In some embodiments of the present invention, the actuating body further includes a connecting block 340, and the first connecting rod 320 and the second connecting rod 330 are respectively connected to the main body 100 and the lens module 200 through the connecting block 340.

For example, as shown in fig. 5, the actuating body further includes a connecting block 340, and the first link 320 and the second link 330 are connected to the main body 100 and the lens module 200 through the connecting block 340, respectively. The connection between the first link 320 and the second link 330 is more stable by the arrangement of the connection block 340. Further, a straight line connecting the two connecting blocks 340 of the same actuating body is perpendicular to the optical axis S.

In some embodiments of the present invention, the actuator assemblies 300 are provided with a plurality of sets, and the plurality of sets of actuator assemblies 300 are respectively disposed on two sides of the optical axis S and are both the first connecting rod 320 or the second connecting rod 330 on a side close to the optical axis S.

The actuator assembly 300 may be provided with a plurality of groups, and may be respectively disposed on two sides of the optical axis S of the lens module 200 and also be the first link 320 or the second link 330 on a side close to the optical axis S. For example, as shown in fig. 4, two sets of actuator assemblies 300 are provided, and the two sets of actuator assemblies 300 are respectively located at two sides of the lens module 200.

The actuator assemblies 300 on the same side of the optical axis S are the same as the first connecting rod 320 or the second connecting rod 330 on the side close to the optical axis S, so that the actuator assemblies 300 on the same side of the optical axis S can drive the lens module 200 in the same direction, and cannot drive in the opposite direction, and the phenomenon that the actuator assemblies 300 cannot normally drive the lens module 200 occurs.

The two sets of actuator assemblies 300 are the same as the second connecting rod 330 on the side close to the optical axis S, so that the actuator assemblies 300 on the two sides of the optical axis S of the lens module 200 can drive the lens module 200 in opposite directions, and when the lens module 200 needs to be driven to the right side, the actuator assembly 300 on the left side of the optical axis S can be started; the actuator assembly 300 located at the right side of the optical axis S can be activated when it is required to drive the lens module 200 to the left side, thereby driving the lens module 200 from different directions to achieve the anti-shake effect of the lens.

In some embodiments of the present invention, the multiple sets of actuator assemblies 300 are located at the top or bottom of the lens module 200 at the same time.

For example, as shown in fig. 2 and 3, two sets of actuator assemblies 300 are simultaneously located on top of the lens module 200. By simultaneously disposing the plurality of sets of actuator assemblies 300 on the top or bottom of the lens module 200, the internal space utilization of the lens assembly is made higher.

In some embodiments, four support rods 400 are provided, and are respectively disposed at four corners of the lens module 200 to support the lens module 200.

By such arrangement, the lens module 200 can be suspended in the main body 100 through the supporting rod 400, so that the friction force between the lens module 200 and the main body 100 when the actuator assembly 300 drives the lens module 200 to move to realize the anti-shake function can be reduced, the movement of the lens module 200 driven by the actuator assembly 300 is more accurate, and the service life of the lens module 200 is longer.

In some embodiments of the present invention, one end of the supporting rod 400 is connected to the bottom wall of the main body 100, and the other end is connected to the top wall of the lens module 200.

For example, as shown in fig. 2 and 3, the support rod 400 has one end connected to the bottom wall of the main body 100 and the other end connected to the top wall of the lens module 200. The lens module 200 is provided with an avoiding groove at a corresponding position of the supporting rod 400, so that the supporting rod 400 can penetrate through the lens module 200 through the avoiding groove to extend into the upper side of the lens module 200, and is connected with the top wall of the lens module 200 through the elastic connector 500. The support rod 400 has a certain elasticity so that the actuator assembly 300 can drive the lens module 200 to move and can be reset.

In some embodiments of the present invention, the lens module further includes an elastic connector 500, the elastic connector 500 is disposed on the lens module 200 and/or the main body 100, and the supporting rod 400 is connected to the lens module 200 and/or the main body 100 through the elastic connector 500.

For example, as shown in fig. 4 and 6, an elastic connector 500 is disposed on the top wall of the lens module 200, and one end of the supporting rod 400 is fixedly connected to the main body 100, and the other end is connected to the lens module 200 through the elastic connector 500. By such an arrangement, the lens module 200 can be suspended in the main body 100, and the movement in the main body 100 is not hindered by friction, and the lens module can be easily moved and reset through the elastic connection member 500.

In some embodiments of the present invention, the main body 100 further includes a fixing plate 130, and the main body 100 is connected to the actuator assembly 300 through the fixing plate 130.

As shown in fig. 2 and 3, the main body 100 further includes a fixing plate 130, and the main body 100 is connected to the actuator assembly 300 through the fixing plate 130.

The lens assembly is more conveniently mounted by providing the fixing plate 130 such that the body portion 100 is coupled to the actuator assembly 300 through the fixing plate 130 rather than directly coupling the actuator assembly 300 to the body portion 100. When mounting, the lens module 200 may be mounted on the base 120, the actuator assembly 300 and the fixing plate 130 are coupled with the lens module 200, and the upper case 110 may be mounted. Instead of providing the base 120 and the upper case 110, the lens module 200, the actuator assembly 300, and the fixing plate 130 may be connected and then installed in the receiving cavity of the main body 100. This is more convenient than mounting directly in the receiving cavity of the main body part 100 without providing the fixing plate 130.
