According to the camera module of the embodiment of the application, the four driving members, i.e. the first driving member 111, the second driving member 121, the third driving member 122 and the fourth driving member 112, work alternately, which is different from the case of providing three driving members, so that not only can the focusing of the lens assembly be realized, but also the focusing efficiency is greatly improved.
The first, second, third and fourth driving members 111, 121, 122 and 112 may adopt different driving manners, and in an embodiment provided by the present application, as shown in fig. 8.
In this embodiment, the first driving member 111, the second driving member 121, the third driving member 122 and the fourth driving member 112 have the same structure, and each of them includes: a memory metal piece 100 and a heating mechanism.
The memory metal part 100 is a special alloy material, mainly made of nickel-titanium alloy, and can be restored to the original shape after being heated, deformed and cooled, thereby having the memory capability. The memory metal device 100 has a first configuration corresponding to an elongated state and a second configuration corresponding to a contracted state.
In the case of using the temperature control memory metal member 100, the shape of the memory metal member 100 can be adjusted by changing the ambient temperature of the memory metal member 100. For example, when the memory metal device 100 is heated and the temperature reaches a certain threshold, the memory metal device 100 is elongated, and the memory metal device 100 is transformed from the contracted state to the elongated state. After the temperature is lowered, the memory metal 100 contracts and returns from the elongated state to the contracted state.
In other embodiments, the memory device 100 can be directly controlled by voltage or current, and in the case of controlling the shape of the memory device 100 by voltage (or current), the shape of the memory device 100 can be adjusted by changing the voltage (or current) applied to the memory device 100. For example, when the voltage applied to the memory metal device 100 reaches a certain threshold, the memory metal device 100 is extended, and the memory metal device 100 is converted from the contracted state to the extended state. When the voltage applied to the memory metal device 100 is reduced, the memory metal device 100 contracts and returns from the extended state to the contracted state.
The heating mechanism can be disposed around the memory metal member 100 or directly in the memory metal member 100. The heating mechanism also has a first temperature state and a second temperature state corresponding to the first form and the second form. When the heating mechanism is in the second temperature state, the heating mechanism heats the memory metal part 100 to the temperature threshold value.
When the heating mechanism is in the first temperature state and the temperature is reduced to the normal temperature, the memory metal part 100 is cooled and deformed to the first shape, and the memory metal part 100 is contracted. The heating mechanism is configured to heat and deform the marmem 100 to a second shape in a second temperature state, for example, when the temperature rises to a threshold value, the marmem 100 elongates to the second shape.
The memory metal part 100 is adopted to focus the camera module, after focusing is completed, power does not need to be conducted, the displacement in the small-step focusing process is adjustable and small each time, therefore, the required driving force is very small, the power consumption of the camera module in the focusing process can be greatly reduced, a magnetic structure is not arranged in a focusing driving component, and the electromagnetic interference among the multiple camera modules can be optimized.

In the case where the coil 110 generates an ampere force to the permanent magnet 1201 toward the left, the driving member is in a contracted state, and the permanent magnet 1201 drives the carrier 1202 to move to the side of the first slide rail close to the coil 110.
To avoid that the permanent magnet 1201 is in direct contact with the coil 110, the magnetic driver 120 further comprises: the elastic member 1203.
