Problems solved by technology

[0002] Terminal equipment with camera modules, such as mobile phones, AR, VR helmets, etc., usually need to adjust the optical path of the optical system in the camera module through a micro motor, because the camera module usually needs to drive optical devices to focus and stabilize And various forms of motion such as twisting, so when the existing camera module drives different motions, it usually needs to set up a plurality of different driving mechanisms to cooperate with each other to complete the required motion. Therefore, the driving mechanism in the existing mobile terminal Usually complex and numerous

no. 1 example

[0045] refer to Figure 1-Figure 2 , to provide a universal actuator, including: a base 110, a platform 120 and three supports 130, wherein, the base 110 includes a ring-shaped bottom plate 111 and a plurality of elongated vertical bars standing between the inner circumference and the outer circumference of the bottom plate 111 For the plate 112, a plurality of vertical plates 112 are connected end to end to form a polygon, for example, the polygon can be inscribed with the outer circumference of the circular bottom plate 111. Here, in this embodiment, the bottom plate 111 may be configured as a circular ring, and in some other embodiments, the bottom plate 111 may be configured as a square ring.

[0046] Further, in this embodiment, the number of vertical plates 112 may be six, of course, in other embodiments, the number of vertical plates may be other numbers, such as eight, nine and so on. In addition, in some other embodiments, the bottom plate 111 may also be configured ...

[0059] refer to Image 6 and Figure 7 , this embodiment provides a universal actuator, which is different from the first embodiment in that, in this embodiment, in order to allow the platform 220 to press the supporting member 230, the elastic sheet 290 is used instead of the first embodiment. For the elastic member 142 , the restoring force is completely realized by the cooperation of the magnetic conductive sheet 253 and the magnet 251 . For the structure of other parts, reference may be made to the first embodiment, which will not be repeated here.

[0060]In this embodiment, in order to enable the platform 220 to be pressed against the support member 230 , the universal actuator further includes an elastic piece 290 , one end of which is fixed to the platform 220 and the other end to the support member 230 . The elastic piece 290 has the function of pressing the platform 220 . Tighten the elastic force of the protrusion 231 . At this time, one end of the elastic sheet ...

[0066] refer to Figure 8 , this embodiment provides a universal actuator. The difference from the first embodiment is that in this embodiment, the driving mechanism 350 is replaced by an SMA driver instead of an electromagnetic driver, and the structure of the platform 320 is adaptively adjusted. The bearing mode of the 320 is completed by the bearing portion 341, and the design of the support member is cancelled, and the structure of other parts can be referred to the first embodiment for details, which will not be repeated here.

[0067] In this embodiment, the platform 320 may be configured as a stepped shaft, that is, the outer peripheral surface of the platform 320 has a large diameter section 321 and a small diameter section 322, wherein the large diameter section 321 is located away from the base 310, that is, the small diameter section 322 is close to the base 310 is arranged to form a stepped surface toward the base 310 . Of course, in this embodiment, the platform ...

Abstract

The invention relates to a universal actuator, a camera module and terminal equipment, and the universal actuator comprises a platform which is used for installing an optical device; the driving part comprises three driving mechanisms arranged around the platform; the three driving mechanisms are arranged on the platform, the base is used for fixing the driving mechanisms, the platform is provided with three driving positions corresponding to the three driving mechanisms respectively, the three driving positions are not collinear, and the three driving mechanisms are used for driving the platform to be close to or away from the base at the corresponding driving positions respectively. In the using process, the universal movement of the platform can be achieved only through mutual combination of linear movement of the three driving positions of the driving platform, the structure is simple, the universal movement can be achieved only through a simple linear driving mechanism, and a complex driving system does not need to be arranged.

Description

technical field [0001] The present disclosure relates to the field of electronic equipment photography, and in particular, to a universal actuator, a camera module and a terminal device. Background technique [0002] Terminal equipment with camera modules, such as mobile phones, AR, VR helmets and other equipment, usually needs to adjust the optical path of the optical system in the camera module through a micro motor, because the camera module usually needs to drive optical devices for focusing and anti-shake. and twisting and other forms of movement, so when the existing camera module drives different movements, it is usually necessary to set up a plurality of different driving mechanisms to cooperate with each other to complete the required movement. Therefore, the driving mechanism in the existing mobile terminal Usually the structure is complex and numerous. SUMMARY OF THE INVENTION [0003] The purpose of the present disclosure is to provide a universal actuator, a ...
