Prism device applied to periscopic lens module and periscopic lens module

Abstract

The invention provides a prism device applied to a periscopic lens module and the periscopic lens module. The prism device applied to the periscopic lens module comprises a bearing frame, a supportingreset component, a prism and a plurality of shape memory alloy wires, wherein the supporting reset component is rotationally installed on the bearing frame, the prism is installed on the supporting reset component and can rotate along with the supporting reset component, and the shape memory alloy wires are connected between the bearing frame and the supporting reset component to be used for driving the supporting reset component and the prism to rotate relative to the bearing frame; and two opposite sides of the bearing frame are provided with a plurality of limit slots, two opposite sides of the supporting reset component are provided with a plurality of limit support arms, the plurality of limit support arms are clamped and inserted into the plurality of limit slots respectively, and the limit support arms and the limit slots are in clearance fit so that the limit support arms have activity space in the corresponding limit slots. According to the prism device, since the two opposite sides of the bearing frame are provided with the plurality of limit slots and all the limit support arms on the supporting reset component are clamped and inserted into all the limit slots respectively, the situation that the supporting reset component deviates out of the bearing frame in the using process is avoided.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of imaging equipment, in particular to a prism device applied to a periscope lens module and a periscope lens module with the prism device. [0003] 【Background technique】 [0004] The periscope lens module is a lens module in which the optical zoom is completed inside the fuselage. A periscope lens module generally includes a lens device, a prism device, and an image sensor. In a periscope lens module in the prior art, the prism device generally includes a carrier, a rotating seat, a prism mounted on the rotating seat, and a The rotary drive assembly that drives the rotary base to rotate relative to the fixed base is composed of a rotary drive assembly. However, in the prior art, the rotation angle of the rotary base is limited by the baffles on both sides of the fixed base. When the force on the rotary drive assembly deviates, it is very difficult to It is easy to cause the rotation base to shift, resulting...
