The motor of flatness and auto-focusing, the motor are connected with rod memorial alloy between shell and camera lens carrier, pass through memory
The deformation of alloy drives the camera lens carrier to realize focus function.But if memorial alloy will produce deformation, it is necessary to connect electricity
Stream, memorial alloy one end connected with outer casing of the motor, other end connection lens carrier, shell is metal material, can be used reluctantly
In conducting electric current, but camera lens carrier is plastic cement material, is not used to conducting electric current, memorial alloy be not turned on electric current at all and
Produce deformation；In addition, to adjust flatness（Correct the inclination angle of camera lens carrier）If, just have in different memorial alloys
In be also turned on electric current of different sizes, and shell can not simultaneously turn on electric current of different sizes as an entirety.Understand,
The motor can not realize regulation flatness and automatic focusing function at all.
Utility model content

The autofocus motor is compact-sized, assembling is simple, and the function using memorial alloy adjustable inclination and auto-focusing can be achieved.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of autofocus motor, including base and the carrier that is arranged on the base, be provided with the base to
Few three groups of connection terminals, every group of connection terminal include a positive terminal and a negative terminal；The carrier and base it
Between be connected with least three memorial alloy posts, every memorial alloy post is taken the shape of the letter U, and its head both ends is connected with the base, its
Bottom is connected with the carrier；A piece memorial alloy post corresponds to one group of connection terminal, and its head both ends connects with the group respectively
The positive terminal and negative terminal of connecting terminal are electrically connected with.
Further, at least three memorial alloy posts are arranged in the base and carrier in a manner of isogonism biases
Around central through hole.
Further, the quantity of the memorial alloy post is four.
Further, the periphery of the carrier is provided with outer convex edge, and the bottom of every memorial alloy post is both connected to described
On outer convex edge.
Further, the memorial alloy post passes through the outer convex edge, then bends 180 °, finally again passes through described outer
Convex edge.
Further, the connection terminal is metal PIN.
Further, in addition to the shell that is set on the base.
A kind of camera module, including above-mentioned autofocus motor.
The utility model has the advantages that：The autofocus motor is compact-sized, assembling is simple, its base and load
Connected between body by least three memorial alloy posts, after the memorial alloy post is powered, utilize the length of memorial alloy post
The principle changed with the size variation of current/voltage realizes adjustable inclination and focus function.
