In the present case, the base for the lens driving mechanism is arranged in the direction shown in fig. 1 and 2, so in the lower embodiments, the side of the base facing the carrier is the upper side, and the direction of the base away from the carrier is the lower side.

A mount for a lens driving mechanism according to an embodiment of the present invention is described below with reference to the accompanying drawings, as shown in fig. 1, the lens driving mechanism including: the lens driving mechanism comprises a shell 1, an upper reed 2, a carrier 3, a coil assembly, a magnet assembly, a lower reed 6 and a base 7 for the lens driving mechanism, wherein the upper reed 2, the carrier 3 and the lower reed 6 are sequentially installed in a space defined by the shell 1 and the base 7 from top to bottom.

Meanwhile, as shown in fig. 1 to 4, the carrier 3 has a hollow portion 31 therein, the optical element 8 is mounted in the hollow portion 31, the coil assembly is disposed opposite to the magnet assembly, and either one of the magnet assembly and the coil assembly is disposed on the carrier 3, and the other is fixed in a space defined by the housing 1 and the base 7, the carrier 3 is movably connected to the base 7 by the lower spring 6, the carrier 3 is movably fixed in a space defined by the housing 1 and the base 7 by the upper spring 2, and in addition, the base 7 has a circuit board 71, and the lower spring 6 is electrically connected to the coil assembly and the circuit board 71, respectively, so that the electrical connection between the circuit board 71 and the coil assembly can be realized, and the magnitude of the electric quantity of the coil assembly and whether the coil assembly is electrified or not can be controlled by the circuit board 71.

As shown in fig. 2 to 4, either one of the base 7 and the carrier 3 has at least one insert, the other has at least one groove 32, the adhesive soft body is disposed in the groove 32, and the insert extends from either one of the base 7 and the carrier 3 to the other direction, for example, when the base 7 has the insert, the insert extends from the side of the base 7 facing the carrier 3 to the carrier 3, and when the carrier 3 has the insert, the insert extends from the side of the font facing the base 7 to the base 7, each insert corresponds to each groove 32 one by one, each insert is disposed in the corresponding groove 32, and the outer peripheral profile of the insert is smaller than or equal to the inner peripheral profile of the groove 32.

Since the lens driving mechanism includes: the upper spring leaf 2, the carrier 3 and the lower spring leaf 6 are placed in the space defined by the housing 1 and the base 7 in this order from top to bottom. Wherein the carrier 3 is used for fixing the optical element 8, and the optical element 8 can be driven to move by driving the carrier 3 to move. And the lens driving mechanism further includes: and the coil assembly and the magnet assembly are arranged oppositely, one of the coil assembly and the magnet assembly is arranged on the carrier 3, the other one of the coil assembly and the magnet assembly is fixed in a space defined by the shell and the base 7. The current of coil in the coil assembly is controlled, the magnetic acting force between the coil assembly and the magnet assembly can be controlled, and the carrier 3 can be driven to move relative to the base 7 through the mutual magnetic acting force between the coil assembly and the magnet assembly, so that the optical element 8 is driven to move.

In addition, because at least one insert is arranged on any one of the base 7 and the carrier 3, at least one groove 32 is arranged on the other one, and the adhesive soft body is arranged in the groove 32, the insert is positioned in the corresponding groove 32, and the outer peripheral outline of the insert is less than or equal to the inner peripheral outline of the groove 32. Thus, when the insert is positioned in the recess 32, the adhesive soft material sticks to the inner wall of the recess 32 and also sticks to the insert. When the coil component and the magnet component interact to drive the carrier 3 to move relative to the base 7, the outer peripheral profile of the plug-in is smaller than the inner peripheral profile of the groove 32, so that the plug-in can move up and down or swing in the groove 32, the movement amplitude of the carrier 3 can be larger, and the movement flexibility of the carrier 3 is improved. In addition, the structure of the insert and the groove 32 can ensure that the connection between the carrier 3 and the base 7 is more stable, and the risk of degumming between the carrier 3 and the base 7 due to overlarge movement amplitude is reduced.
