A focus motor that can realize optical zoom and optical image stabilization at the same time

Abstract

A focusing motor capable of realizing optical zooming and optical anti-vibration simultaneously. The end portion of a magnet yoke (5) of an automatic focusing motor is provided with a multiple optical zooming device. The multiple optical zooming device comprises a translation coil assembly (7) mounted on the end surface of the magnet yoke (5), a support (8) movably connected to the translation coil assembly (7), a magnet set fixed on the support (8) and a lens group. The translation coil assembly (7) interacts with the magnet set to control the support (8) to move multi-axially within a plane parallel to the translation coil assembly (7). The focusing motor has a small size, low cost and good anti-vibration effect, can realize multiple optical zooming, and can fully meet the requirements of existing ultra-light and ultrathin intelligent portable mobile apparatuses.

Description

technical field [0001] The present invention relates to a motor device for controlling the movement of a lens. Background technique [0002] The existing handheld mobile devices are basically equipped with cameras, which can enable people to record beautiful moments anytime and anywhere. When people use smart phones, tablet computers and other devices to take pictures, because there is no support from a tripod, their hands are easy to shake, causing jitter. Makes the photos taken blurry. [0003] Such as Figure 5 As shown, the patent document with the publication number CN103826053A discloses an electronic device, a camera and an optical anti-shake camera device. The prior art is located on the bottom side of the autofocus motor, that is, the bottom of the inner base 106, and is provided with multiple translation coils 107 drives the auto-focus motor to perform slight displacements in a plane parallel to the translation coil 107.

[0002] The existing handheld mobile devices are basically equipped with cameras, which can enable people to record beautiful moments anytime and anywhere. When people use smart phones, tablet computers and other devices to take pictures, because there is no support from a tripod, their hands are easy to shake, causing jitter. Makes the photo taken blurry

[0003] like Figure 5 As shown, the patent document with the publication number CN103826053A discloses an electronic device, a camera and an optical anti-shake camera device. The prior art is located on the bottom side of the autofocus motor, that is, the bottom of the inner base 106, and is provided with multiple translation coils 107 drives the auto-focus motor to perform small displacements in the plane parallel to the translation coil 107, because its displacement range in the plane is too small, it is difficult to expand the function

[0004] In addition, this existing technology needs to add multiple sets of components outside the autofocus motor, resulting in the overall horizontal and vertical dimensions of the product being too large, which cannot be applied to existing smart portable mobile devices, and does not have an optical zoom function. Can not meet the needs of users well

[0005] This prior art includes two sets of iron shells (inner iron shell 104 and outer iron shell 108), two sets of bases (inner base 106 and outer base 105), multiple springs (upper spring piece 110, lower spring piece 130 and translation spring piece 109), a plurality of magnets, a plurality of coils, and a lens holder (carrier 101), although tiny anti-shake can also be achieved, the volume and quality of the object to be driven is relatively large, that is, an iron shell (inner iron shell) needs to be driven 104), multiple magnets (magnet 103), lens holder (carrier 101), lens, inner base 106, multiple springs (upper spring piece 110, lower spring piece 130, and translation spring piece 109), coils, resulting in high power consumption of the product , causing the portable mobile device to fail to provide the corresponding conditions for
