Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] It should be noted that all directional indications (such as up, down, inside, outside, top, bottom...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] It should also be noted that when an element is referred to as being “fixed” or “disposed on” another element, the element may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0029] see Figure 1-8 , the embodiment of the present invention provides a prism device 1 applied to a peris...

Abstract

The present invention provides a prism device applied to a periscope lens module and a periscope lens module. The prism device includes a carrier, a support, a prism mounted on the support for receiving light, and a A number of shape memory alloy wires between the support and the carrier to drive the support to rotate relative to the carrier, and a wire connected between the support and the carrier for the reset of the support Reset device. In the present invention, several shape-memory alloy wires are used to drive the support and the prism fixed on it to rotate relative to the carrier, so that the prism can automatically correct its angle and improve the imaging quality. At the same time, the shape-memory alloy wire is used to replace the original electromagnetic drive, thereby reducing the production cost of the prism device applied to the periscope lens module, so as to realize the mass production of the periscope lens module.

Description

【Technical field】 [0001] The invention relates to the technical field of optical imaging, in particular to a prism device used in a periscope lens module in mobile electronic devices such as mobile phones. 【Background technique】 [0002] In recent years, high-performance lens modules have been mounted on portable terminals such as smartphones and tablet computers. The high-performance lens module generally has an automatic anti-shake function. In the prior art, the structure for realizing the automatic anti-shake function usually uses an electromagnetic driving device. The electromagnetic driving device includes a magnet and a coil, and energizes the coil to control the rotation of the prism to realize the correction of the prism angle. However, the electromagnetic driving device is susceptible to interference from external electromagnetic fields, and the use of magnets increases the overall weight and cost of the lens module. [0003] Therefore, it is necessary to provide...
