Problems solved by technology

However, current prisms are generally supported by prism brackets, and most prism brackets also have a driving device to drive the movement of the prism to correct the deviation of refracted light. The shrapnel used is two different shrapnels connected separately, which not only increases the cost, but also may cause the problem of inconsistent shaking of the double shrapnel, which is also not conducive to the development trend of miniaturization of mobile phone camera motors.

Embodiment 1

[0038] A prism driving device, comprising a Y-axis support part (1), and an X-axis support part (2) arranged on the Y-axis support part (1).

[0039] Wherein, the Y-axis support part (1) Y-axis support body (11), the first magnets (12) arranged on both sides of the Y-axis support body (11), and the first magnets (12) cooperate The first coil (13). More specifically, in this embodiment, a mounting groove (14) is respectively provided on both sides of the Y-axis supporting body (11), the first magnet (12) is arranged in the mounting groove (11), and the first coil (13) is arranged outside the first magnet (12). After the first coil (13) is energized, the Y-axis supporting body (11) is driven to move along the Y-axis direction in the magnetic field of the first magnet (12).

[0040] The X-axis support part (2) includes an X-axis support body (21), a second magnet (22) arranged below the X-axis support body (21), and a first magnet (22) matched with the second magnet (22). Seco...

Abstract

The invention discloses a prism driving device which comprises a Y-axis supporting part which comprises a Y-axis supporting body, first magnets arranged on the two sides of the Y-axis supporting body and first coils matched with the first magnets; an X-axis supporting part which comprises an X-axis supporting body, a second magnet arranged below the X-axis supporting body and a second coil matched with the second magnet; a double-section type elastic piece is further included, and the Y-axis supporting body and the X-axis supporting body are both connected with the double-section type elastic piece. According to the invention, the two segments of elastic pieces are adopted to bear the two carriers which are independently arranged, and the carrier in the X-axis direction and the carrier in the Y-axis direction respectively move in different directions, so that the anti-shake function of the prism is realized, and the deviation of refracted light of the prism is corrected.

Description

technical field [0001] The invention relates to the field of motors, in particular to a prism driving device, a photographing device and electronic equipment. Background technique [0002] Prisms are mostly used in periscope motors. The prisms are used to change the propagation direction of light, so that the lens driving device inside the periscope motor can have a larger stroke and achieve higher imaging accuracy. However, current prisms are generally supported by prism brackets, and most prism brackets also have a driving device to drive the movement of the prism to correct the deviation of refracted light. The shrapnel used is two different shrapnels connected separately, which not only increases the cost, but also may cause the problem of inconsistent shaking of the two shrapnels, which is also not conducive to the development trend of miniaturization of mobile phone camera motors. Contents of the invention [0003] The purpose of the present invention is to provide ...
