Technical Field
[0001] This utility model relates to the field of mobile phone lens image stabilization technology, specifically to an image stabilization device for mobile phone lenses. Background Technology
[0002] As mobile phone cameras achieve higher resolutions and lenses and editing applications become more professional, mobile phone photography is gaining more popularity and attention. In addition to the hardware capabilities of the mobile phone camera itself, the photographer's skill level is undoubtedly a crucial factor in determining the image quality. Furthermore, the image stabilization device in the mobile phone lens is a key technology for improving shooting quality, especially in handheld shooting or action scenarios, effectively reducing blur caused by shaking.
[0003] Existing external mobile phone lens image stabilization devices have certain limitations in fixing different mobile phones. Different models of image stabilization devices need to be made according to different mobile phone models, which results in high mold costs. Moreover, during use, the existing image stabilization devices have poor overall image stabilization effect on the mobile phone due to external shaking or collisions, which in turn leads to poor image stabilization effect of the lens and problems such as blurry photos. To address these issues, we propose a mobile phone lens image stabilization device. Utility Model Content
[0004] The purpose of this invention is to provide a stabilization device for mobile phone lenses to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone lens image stabilization device, comprising an outer frame, an inner mounting frame, four sets of symmetrically distributed clamping blocks within the mounting frame, two sets of symmetrically distributed first adjusting rods within the mounting frame, two sets of symmetrically distributed second adjusting rods within the mounting frame, the two sets of first adjusting rods and second adjusting rods being perpendicularly distributed, the four sets of clamping blocks being slidably connected to corresponding sets of first and second adjusting rods, two sets of vertically distributed bidirectional lead screws within the mounting frame, a first sliding rod being fixedly installed within the mounting frame, and two sets of symmetrically distributed brackets between each side of the mounting frame and the outer frame, both sets of brackets being rotatably connected to the mounting frame via a pivot.

The two ends of the two sets of bidirectional lead screws pass through the two sets of first adjusting rods or the two sets of second adjusting rods and are threadedly connected to the corresponding two sets of first adjusting rods and second adjusting rods, respectively.
[0007] As a further preferred embodiment of this technical solution, two sets of symmetrically distributed ratchet wheels are sleeved on the bidirectional lead screw, and two sets of pawls that mesh with the ratchet wheels are provided in the mounting frame.

Two sets of racks that mesh with the gears are slidably installed in the mounting frame, and the two sets of racks are fixedly connected by a connecting bracket. A first spring is sleeved on the first sliding rod.
[0008] As a further preferred embodiment of this technical solution, a first torsion spring is sleeved on the rotating rod, and the two ends of the first torsion spring are respectively fixedly connected to the pawl and the mounting frame. The connecting frame is slidably connected to the mounting frame, and a locking block is fixedly installed on the connecting frame.

[0012] This utility model provides a mobile phone lens image stabilization device, which has the following beneficial effects:
[0013] This invention uses a bidirectional lead screw to rotate within the mounting frame, thereby adjusting the distance between the two sets of first and second adjusting rods, and consequently adjusting the distance between the four sets of clamping blocks. This allows the image stabilization device to be used with different mobile phone models, thus providing image stabilization protection for different mobile phone lenses.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, a mobile phone lens image stabilization device includes an outer frame 1, a mounting frame 2 inside the outer frame 1, four sets of symmetrically distributed clamping blocks 3 inside the mounting frame 2, two sets of symmetrically distributed first adjusting rods 4 inside the mounting frame 2, and two sets of symmetrically distributed second adjusting rods 5 inside the mounting frame 2. The two sets of first adjusting rods 4 and second adjusting rods 5 are perpendicularly distributed. The four sets of clamping blocks 3 are slidably connected to the corresponding set of first adjusting rods 4 and second adjusting rods 5. The mounting frame 2 includes two sets of vertically distributed bidirectional lead screws 6. A first sliding rod 15 is fixedly installed inside the mounting frame 2. Two sets of symmetrically distributed brackets 21 are provided between each side of the mounting frame 2 and the outer frame 1. Both sets of brackets 21 are connected to the mounting frame 1 via a pivot. The mounting frame 2 is rotatably connected. Both ends of the bidirectional lead screw 6 pass through the mounting frame 2 and are rotatably connected to it via bearings. Both ends of the two sets of bidirectional lead screws 6 pass through two sets of first adjusting rods 4 or two sets of second adjusting rods 5 and are threadedly connected to the corresponding sets of first adjusting rods 4 and second adjusting rods 5. Two sets of symmetrically distributed ratchet wheels 7 are sleeved on the bidirectional lead screw 6. The mounting frame 2 has two sets of pawls 9 that mesh with the ratchet wheels 7. Both sets of pawls 9 are rotatably connected to the mounting frame 2 via rotating rods 10. Gears 12 are sleeved on both sets of rotating rods 10. Two sets of racks 13 that mesh with the gears 12 are slidably installed inside the mounting frame 2. The two sets of racks 13 are fixedly connected by a connecting bracket 14. The first sliding rod 15... A first spring 16 is sleeved on the rotating rod 10, and a first torsion spring 11 is sleeved on the rotating rod 10. The two ends of the first torsion spring 11 are fixedly connected to the pawl 9 and the mounting frame 2, respectively. The connecting frame 14 is slidably connected to the mounting frame 2, and a locking block 17 is fixedly installed on the connecting frame 14. The connecting frame 14 is slidably sleeved with the first sliding rod 15. The two ends of the first spring 16 are fixedly connected to the connecting frame 14 and the mounting frame 2, respectively. A locking rod 18 corresponding to the locking block 17 is fixedly installed inside the mounting frame 2. Two sets of symmetrically distributed locking brackets 19 are sleeved on the locking rod 18, and both sets of locking brackets 19 are movably locked with the locking block 17. A second torsion spring 20 is sleeved on the locking rod 18, and the two ends of the second torsion spring 20 are respectively connected to the locking brackets. 19 and 18 are fixedly connected. When the two sets of brackets 19 fix the bracket 17, the connecting frame 14 drives the two sets of racks 13 to cooperate with the gear 12, so that the rotating rod 10 drives the pawl 9 to deviate from the corresponding ratchet 7. Therefore, the bidirectional screw 6 can rotate flexibly according to actual needs. The rotation of the two sets of bidirectional screws 6 in the mounting frame 2 realizes the adjustment of the distance between the two sets of first adjusting rods 4 and second adjusting rods 5. Then, while the position of the rods between the first adjusting rods 4 and second adjusting rods 5 changes, the distance between the four sets of clamping blocks 3 is adjusted. This allows for clamping of different models of mobile phones, effectively expanding the application range of the anti-shake device, improving its adaptability, and saving the mold opening cost of the anti-shake device. After the adjustment of the distance between the four sets of clamping blocks 3 is completed,When the clip 19 is released from its fixation on the clip 17, the pawl 9 returns to its original engagement with the ratchet 7 under the action of the first spring 16 and the first torsion spring 11. Under the action of the two sets of pawls 9 and the ratchet 7, the bidirectional lead screw 6 cannot rotate, and the spacing between the four sets of clamping blocks 3 cannot change, thus ensuring the stability of the anti-shake device in fixing the mobile phone.
[0022] like Figure 2 and Figure 4 As shown, a slider 22 is rotatably mounted on one end of the bracket 21 near the outer frame 1. A second sliding rod 23, corresponding to the slider 22, is fixedly mounted inside the outer frame 1. An air spring 8 is provided between the slider 22 and the outer frame 1. The two ends of the air spring 8 are fixedly connected to the slider 22 and the outer frame 1, respectively. The slider 22 is slidably sleeved with the second sliding rod 23. A second spring 24 is sleeved on the second sliding rod 23. The two ends of the second spring 24 are fixedly connected to the slider 22 and the outer frame 1, respectively. When the user holds the anti-shake device, the force and movement of the hand are directly applied to the outer frame 1. During the movement of the outer frame 1, the mounting frame 2 and the mobile phone tend to move due to inertia. When the mounting frame 2 moves up, down, left, and right, it will squeeze the bracket 21 and the slider 22. The second spring 24 and the air spring 8 absorb the pressure of the device and slowly release it to achieve the anti-shake protection effect for the mounting frame 2 and the mobile phone fixed in the mounting frame 2, so that the shaking amplitude of the mobile phone and the mounting frame 2 is minimized and the blurring of the mobile phone lens due to shaking is avoided.
[0023] This utility model provides a mobile phone lens image stabilization device. The specific working principle is as follows: When two sets of brackets 19 fix the clip 17, the connecting frame 14 drives two sets of racks 13 in conjunction with gears 12, causing the rotating rod 10 to drive the pawl 9 to deviate from the corresponding ratchet 7. Therefore, the bidirectional lead screw 6 can rotate flexibly according to actual needs. The rotation of the two sets of bidirectional lead screws 6 in the mounting frame 2 adjusts the distance between the two sets of first adjusting rods 4 and second adjusting rods 5. Simultaneously, while the position of the first adjusting rod 4 and second adjusting rod 5 changes, the distance between the four sets of clamping blocks 3 is adjusted, allowing for clamping of different mobile phone models. This effectively expands the applicability of the image stabilization device, improves its adaptability, and saves on the mold opening cost of producing the image stabilization device. After adjusting the distance between the four sets of clamping blocks 3, the brackets 19 are released from fixing the clip 17. Under the action of spring 16 and the first torsion spring 11, the pawl 9 returns to its original state of engagement with the ratchet 7. Under the action of the two sets of pawls 9 and ratchet 7, the bidirectional screw 6 cannot rotate, and the distance between the four sets of clamps 3 cannot change, thus ensuring the stability of the anti-shake device for fixing the mobile phone. When the user holds the anti-shake device, the force and movement of the hand are directly applied to the outer frame 1. During the movement of the outer frame 1, the mounting frame 2 and the mobile phone tend to move due to inertia. During the up, down, left and right movement of the mounting frame 2, the bracket 21 and the slider 22 will be squeezed. The second spring 24 and the air spring 8 absorb the pressure of the device and slowly release it to achieve the anti-shake protection effect for the mounting frame 2 and the mobile phone fixed in the mounting frame 2, so that the shaking amplitude of the mobile phone and the mounting frame 2 is minimized, and the blurring of the mobile phone lens due to shaking is avoided.
