Description

Technical Field

[0001] The utility model relates to the technical field of motor test lenses, in particular to a test lens for an OIS motor. Background Art

[0002] Optical image stabilization technology monitors the displacement information of the body shaking and allows the anti-shake module to move in the opposite direction to offset the shaking, thereby effectively suppressing the impact of shaking on mobile phone imaging. Since 2020, different optical image stabilization solutions have been applied in the camera technology of major mainstream mobile phone manufacturers, including lens OIS image stabilization, sensor OIS image stabilization, and floating image stabilization. Lens OIS image stabilization is a relatively common image stabilization technology in various imaging devices.

[0003] The lens module is designed to be movable, or a movable lens that uses magnetic suspension is added to the lens module. The movable lens / lens cooperates with the mobile phone shaking data obtained by the gyroscope, and is driven by the voice coil motor or memory metal mechanical structure to move in the opposite direction to compensate for the light path affected by the body shaking, so that the light after shaking can still fall on the original position, which can bring more stable and clear imaging effects.

[0004] Currently, the test of autofocus motors requires screwing a threaded lens into the motor. The electrical characteristics of the motor are determined by testing the lens's motion trajectory and optical axis. All motors must be fully tested before shipment, and each motor must be screwed into the lens for testing. This is inefficient and may cause damage to the motor during the process.

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of a test lens for an OIS motor of the utility model.

[0014] Figure 2 This is a cross-sectional view of an assembly of a test lens for an OIS motor of the utility model. DETAILED DESCRIPTION

[0015] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0016] Please refer to Figure 1 and Figure 2 A test lens for an OIS motor includes a reflective surface 10, a frame 20 and an elastic rubber ring 30. The reflective surface 10 is fixed to one side of the frame 20. A plurality of partitions 21 are provided on the surface of the frame 20. The partitions 21 are arranged at intervals along the axial direction of the frame 20. The elastic rubber ring 30 is sleeved on the surface of the frame 20, and the elastic rubber ring 30 is restricted from moving along the surface of the frame 20 by the partitions 21. The elastic rubber ring 30 protrudes from the partitions 21.

[0017] During installation, the elastic rubber ring 30 is first sleeved on the surface of the frame 20, and the partition 21 is used to limit the sliding of the elastic rubber ring 30. At the same time, the elastic rubber ring 30 forms an interference fit with the surface of the frame 20, and the elastic rubber ring 30 protrudes from the partition 21. Then, the frame 20 with the elastic rubber ring 30 sleeved is inserted into the test lens barrel 40, and the elastic rubber ring 30 is used to contact the threads on the inner wall of the lens barrel 40, which also achieves the purpose of interference fit. The test lens is fixed in the lens barrel 40, which has high test efficiency. The elastic rubber ring 30 causes zero damage to the lens barrel 40, ensures that the lens barrel 40 and the lens are tightly fitted and clamped, and ensures the test accuracy.

[0018] There are two elastic rubber rings 30 , and the partition 21 is disposed between the two elastic rubber rings 30 . When the test lens is inserted into the lens barrel 40 , a better fixing effect can be achieved, and the partition 21 is used to prevent the two elastic rubber rings 30 from affecting and squeezing each other.

[0019] There are several notches 22 at intervals on the surface of the partition 21, so that when the elastic rubber ring 30 is squeezed, it can have a certain deformation space in the axial direction and can be squeezed out from the notches 22. At the same time, the notches 22 also serve the purpose of reducing weight, reducing the weight of the partition 21.

[0020] The surface of the frame 20 is provided with a plurality of grooves 23, which are arranged at intervals around the axis of the frame 20. Similar to the above, when the elastic rubber ring 30 is squeezed, it can deform toward the groove 23, providing a certain deformation space to avoid the test lens being unable to be inserted into the lens barrel 40 due to excessive squeezing. The hollow structure inside the frame 20 can effectively reduce the overall weight.

[0021] The utility model provides a test lens of an OIS motor. When installing, an elastic rubber ring is first sleeved on the surface of a frame, and a partition is used to limit the sliding of the elastic rubber ring. At the same time, the elastic rubber ring forms an interference fit with the surface of the frame, and the elastic rubber ring protrudes from the partition. Then, the frame sleeved with the elastic rubber ring is inserted into a test lens barrel, and the elastic rubber ring is used to contact with the thread of the inner wall of the lens barrel, which also achieves the purpose of interference fit. The test lens is fixed in the lens barrel, which has high test efficiency. The elastic rubber ring is used to cause zero damage to the lens barrel, so that the lens barrel and the lens are ensured to be tightly fitted and clamped, thereby ensuring the effect of test accuracy.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
