VCM is mainly composed of brackets, magnets, upper and lower shrapnel, bases, coils and casings and other components. The quality of its performance plays a decisive role in the quality of the camera. The voice coil motor has a Tilt (tilt) OIS mechanism to adjust the lens too much. However, most of the existing Tilt OIS structures are two-axis OIS based on the ball structure. The ball structure has many disadvantages in the actual assembly process and reliability verification, such as sticking during the ball movement process, and friction between the ball and plastic parts.

Embodiment 1
[0030] Embodiment one, such as Figure 1 to Figure 10 As shown, an electromagnetic anti-shake pan / tilt based on a camera module proposed by the present invention includes a base 1 and a housing 2 engaged with the base 1; a carrier 3 is arranged between the base 1 and the housing 2, and the A lens 4 is fixed inside the carrier 3; a coil 5 is fixed on the surrounding side walls of the carrier 3, and a magnet 6 used in conjunction with the coil 5 is arranged inside the housing 2; For the tilting mechanism of the drive carrier 3 , the tilting mechanism has four stamping rotating shafts as the supporting points of the rotating shafts, and the four stamping rotating shafts are respectively located in the X-axis and Y-axis directions of the tilting mechanism.
[0031] The housing is provided with a rectangular step surface, the upper side of the fixing frame fits with the step surface box, the lower side of the fixing bracket fits with the upper side box of the magnet, and the fixing...
Embodiment 2
[0050] Embodiment 2, the first punching rotation axis is in the shape of a solid circle.
[0051] In this embodiment, the structure of the first sleeve is consistent with that of the second sleeve, and the first sleeve is in a ring structure with an opening at its upper end.
[0052] In this embodiment, the first rotating frame, the second rotating frame and the fixed frame are stamped in one piece, so that processing is convenient and the structure is more stable.
[0053] In this embodiment, the first rotating frame, the second rotating frame and the fixing frame are made of elastic metal materials.
[0054] In this embodiment, elastic thermosetting glue can be placed on the clamping place of the rotating shaft, which can slow down the impact force damage during reliability verification.
[0055] Working principle of the present invention:
[0056] An annular racetrack coil is installed outside the traditional lens, and a bipolar magnet is installed inside the casing. The ...

Abstract
The invention discloses an electromagnetic anti-shake pan-tilt based on a camera module. The electromagnetic anti-shake pan-tilt comprises a base and a shell connected with the base in a clamped mode.A carrier is arranged between the base and the shell, and a lens is fixed in the carrier; coils are fixed to the side walls of the periphery of the carrier, and magnets used in cooperation with the coils are arranged on the inner side of the shell. An inclination mechanism used for driving the carrier is arranged between the carrier and the magnet, the inclination mechanism is provided with fourstamping rotating shafts serving as rotating shaft supporting points, and the four stamping rotating shafts are located in the X-axis direction and the Y-axis direction of the inclination mechanism respectively. According to the electromagnetic anti-shake pan-tilt based on the camera module, the first rotating frame, the second rotating frame and the fixed frame are arranged, and the first rotating frame can rotate in the X-axis direction and the Y-axis direction through the arrangement of the stamping rotating shafts, and thus the problems in the prior art that the ball is clamped in the moving process and the ball rubs with a plastic part to generate scraps are solved.
Description
technical field [0001] The invention relates to the field of photography, in particular to an electromagnetic anti-shake platform based on a camera module, a voice coil motor and electronic equipment. Background technique [0002] Most camera devices use a VCM (Voice Coil Motor) to complete the up and down movement of the lens through electromagnetic thrust, so as to realize the auto-focus camera function. VCM is mainly composed of brackets, magnets, upper and lower shrapnel, bases, coils and casings and other components. The quality of its performance plays a decisive role in the quality of the camera. The voice coil motor has a Tilt (tilt) OIS mechanism to adjust the lens too much. However, most existing Tilt OIS structures are two-axis OIS based on the ball structure. The ball structure has many disadvantages in the actual assembly process and reliability verification, such as sticking during the ball movement process, and friction between the ball and plastic parts.
