In an embodiment, as shown in fig. 1 and 2, a focusing motor spring mounting structure includes a magnetic conductive base 1, a magnet 2, a coil 3, a spring 4, and a plurality of sets of spring wires 5.
The middle part of the magnetic conduction seat 1 is provided with a cylindrical cavity 11, and a carrier is loaded in the cylindrical cavity 11; the outer side of the magnetic pole is evenly provided with a plurality of magnet 2 installation parts. In this embodiment, the magnetic conductive base 1 is an octagonal cylinder, which includes 4 positive sides and 4 corner sides, and each corner side is disposed between 2 positive sides (or each positive side is disposed between 2 corner sides). 4 nonadjacent sides of the through hole 41 correspond to a magnet 2, namely 4 corner sides are magnet 2 mounting parts, and 4 magnets 2 are assembled on the magnet 2 mounting parts. The coil 3 is assembled on the inner wall of the cylindrical cavity 11, and the components form an electromagnetic induction part. When the coil 3 is electrified, the magnet 2 and the coil 3 form electromagnetic induction force to drive the carrier to move up and down.
The spring plate 4 is assembled on the upper layer surface of the magnetic conduction seat 1, namely the spring plate 4 is assembled on the carrier. Move up and down under the push of the carrier. In this embodiment, the middle of the elastic sheet 4 is provided with a through hole 41 matching with the bottom surface of the magnetic conductive base 1, that is, the shape of the through hole 41 matches with the bottom surface of the magnetic conductive base 1.
4 groups of the spring wires 5 are uniformly assembled on the spring plate 4 and the magnetic conductive seat 1, and each group of the spring wires 5 is correspondingly connected to one side of the through hole 41 and the magnetic conductive body. Each group of the spring wires 5 comprises 2 spring wires 5, and the 2 spring wires 5 in each group are arranged in an axisymmetric manner. Specifically, the spring wire 5 includes a first connecting portion 51, a second connecting portion 52, a third connecting portion 53, and a fourth connecting portion 54. The first connecting portion 51 is vertically connected to one side of one of the through holes 41; the second connecting portion 52 is parallel to the edge of the through hole connected with the first connecting portion 51, and one end of the second connecting portion 52 is connected with the first connecting portion 51; one end of a third connecting portion 53 is connected to the other end of the second connecting portion 52, the third connecting portion 53 is parallel to the other side of the through hole, and the side is adjacent to the side of the through hole 41 connected to the first connecting portion 51; one end of the fourth connecting portion 54 is vertically connected to the other end of the third connecting portion 53, and the other end of the fourth connecting portion 54 is connected to the magnetic conductive base 1. The structure of the spring wire 5 effectively increases the supporting force of the spring wire 5 under the condition of elasticity, and the design of a symmetrical structure is matched, so that the spring wire can counteract the rotating force generated by electromagnetic induction force, and the spring plate 4 is fixed by the spring wire 5 and cannot rotate when moving up and down.
