Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.

Example 1: as shown in fig. 1, the utility model provides a magnetite and frame attach structure, including frame 1 and magnetite 2, magnetite 2 is the cuboid setting, and frame 1 sets up four mounting grooves 3 that supply magnetite 2 to install, and 3 corner positions in mounting groove are provided with step 4, and step 4 sets up to two and is the symmetry setting in this embodiment.

2 both sides lateral wall homogeneous body shaping of magnetite has the extension piece 5 of avoiding step piece 4, and extension piece 5 material is unanimous with magnetite 2, and extension piece 5 deviates from the laminating of 2 one ends of magnetite or is close to 3 lateral walls in mounting groove to extension piece 5 closes as a whole with magnetite 2.

The specific shape of extension piece 5 is the setting of cuboid, and two extension pieces 5 merge with magnetite 2 and are "protruding" font and avoid step piece 4. Through two extension pieces 5 and magnetite 2 can effectively increase the whole volume of magnetite 2, effectively increase the motor and deduce, improve the not enough problem of thrust.

Example 2 differs from example 1 in that: as shown in fig. 2, the two extending blocks 5 are both in a right trapezoid shape, and the inclined surface of the extending block 5 is away from the step block 4.

Example 3: a voice coil motor having the magnet-frame connection structure described in embodiment 1 or embodiment 2, as shown in fig. 3 to 5, further comprising a lens carrier 6 and an upper spring 7, wherein the adjusting block is flush with an end of the upper spring 7 away from the lens carrier 6. Each step block 4 of the frame 1 is integrally formed with a hot riveting column 8, the upper spring 7 is provided with a riveting part 9 corresponding to the step block 4, and the riveting part 9 is provided with a riveting hole 10 sleeved on the hot riveting column 8.

In the present embodiment, two step blocks 4 close to the same corner position of the frame 1 are connected to each other and integrated into a whole, i.e., an equal height plane is formed between the two step blocks 4. The riveting parts 9 of the upper spring 7 are four and are respectively corresponding to the two step blocks 4 at the same corner position of the frame 1, namely the riveting parts 9 can be attached to the end surfaces of the two step blocks 4, the riveting holes 10 of the riveting parts 9 are two, and the two riveting holes 10 are respectively sleeved on the hot riveting columns 8 corresponding to the step blocks 4.
