[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, the positioning structure of a fast-focusing camera provided by this utility model includes:

[0027] Image sensor 1, with lens module 2 on the left side of image sensor 1, and focusing mechanism 3 slidably sleeved on the left side of lens module 2;

[0028] The focusing mechanism 3 includes a lens 31, a connecting block 32, and a slider 33. The lens 31 is slidably sleeved on the left side of the lens module 2. The front and back ends of the bottom of the lens 31 are fixedly connected to the connecting block 32. The bottom of the connecting block 32 is fixedly connected to the slider 33. The bottom left side of the image sensor 1 is fixedly installed with a connecting mechanism 4.

[0029] refer to Figure 4 The connecting mechanism 4 includes a support 41, a fixing block 42, a guide rail 43, and an L-shaped plate 44. The support 41 is fixedly installed on the bottom left side of the image sensor 1. The fixing block 42 is fixedly connected to the top left side of the support 41. The guide rail 43 is fixedly connected to the top of the fixing block 42. The L-shaped plate 44 is slidably connected to the top of the guide rail 43. The top of the L-shaped plate 44 is fixedly connected to the bottom of the slider 33. The end of the L-shaped plate 44 away from the guide rail 43 is slidably connected to the top of the fixing block 42. The drive assembly 5 is fixedly connected to the left side of the support 41.

[0030] As a technical optimization of this utility model, by setting the connecting mechanism 4, the L-shaped plate 44 can be embedded in the inside of the slider 33, and then the L-shaped plate 44 completes horizontal linear movement along the surface of the guide rail 43. The guide rail 43, together with the fixing block 42 and the support 41, keeps the position fixed, thereby achieving stability in the mechanical movement process and avoiding the phenomenon of L-shaped plate 44 shifting during movement.

[0031] refer to Figure 5 The drive assembly 5 includes a voice coil motor 51 and a pusher block 52. The voice coil motor 51 is fixedly connected to the left side of the support 41, and the pusher block 52 is fixedly connected to the output end of the voice coil motor 51. The left side of the pusher block 52 is fixedly connected to the right side of the slider 33.

[0032] As a technical optimization of this utility model, by setting the drive component 5, the voice coil motor 51 can be energized to achieve displacement of the push block 52, so as to achieve precise control of the distance through circuit control, avoiding the mechanical failure due to uncontrollable movement distance of the push block 52.

[0033] refer to Figure 4 A groove 6 is provided on the top of the fixing block 42 and at the position corresponding to the L-shaped plate 44. The groove 6 is used in conjunction with the L-shaped plate 44.

[0034] As a technical optimization of this utility model, the groove 6 enables the L-shaped plate 44 to move inside the groove 6, while also serving as a limit, preventing the L-shaped plate 44 from moving too far and causing the machine to malfunction.

[0035] refer to Figure 4 A slot 7 is provided at the bottom of the slider 33 and at the position corresponding to the L-shaped plate 44. The slot 7 is used in conjunction with the L-shaped plate 44.

[0036] As a technical optimization of this utility model, the slot 7 can assist the L-shaped plate 44 in its work and also play a fixing role, preventing the L-shaped plate 44 from becoming loose and falling out inside the slider 33.

[0037] refer to Figure 4 A groove 8 is provided at the bottom of the L-shaped plate 44 and at the position corresponding to the guide rail 43. The groove 8 is used in conjunction with the guide rail 43.

[0038] As a technical optimization of this utility model, the sliding groove 8 enables the L-shaped plate 44 to move stably on the surface of the guide rail 43, while also serving as a limit, thus preventing the L-shaped plate 44 from tilting during movement.

[0039] refer to Figure 4 The left and right sides of the top of the guide rail 43 are connected by screws 9 via threads. The bottom of the screws 9 passes through the bottom of the guide rail 43 and is movably connected to the top of the fixing block 42.

[0040] As a technical optimization of this utility model, the screw 9 can assist in the installation and fixation of the guide rail 43, avoiding the large gap between the guide rail 43 and the L-shaped plate 44 caused by the increased wear of the guide rail 43 after long-term use, which would affect the stability of mechanical movement.

[0041] refer to Figure 4 The top of slider 33 is movably connected to the top of L-shaped plate 44 by bolts, and slider 33 and L-shaped plate 44 are used together.

[0042] As a technical optimization of this utility model, by setting the slider 33, the slider 33 can be fixed to the top of the L-shaped plate 44 by bolts, thus avoiding the phenomenon of the L-shaped plate 44 detaching inside the slider 33.

[0043] The working principle and usage process of this utility model are as follows: When in use, the voice coil motor 51 is started. The control circuit inputs a current of a specific size and direction into the voice coil of the voice coil motor 51. The voice coil is displaced by the force in the magnetic field, which in turn drives the push block 52 connected to it to move axially. The push block 52 moves to the left, which drives the slider 33 to move accordingly. The slider 33 moves, which drives the L-shaped plate 44 to move accordingly. The L-shaped plate 44 moves stably on the surface of the guide rail 43 in conjunction with the sliding groove 8. The other end of the L-shaped plate 44 moves inside the groove 6, so that the movement distance of the L-shaped plate 44 cannot exceed the length of the groove 6, thus limiting the position. Then, the slider 33 moves to the left, which drives the connecting block 32 and the lens 31 to move synchronously. The lens 31 moves stably along the surface of the lens module 2 to change the focal length. At this time, the lens module 2 collects light and images the object onto the image sensor 1. Then, the image sensor 1 converts the light signal into an electrical signal and records the image information, thereby completing the function of rapid focusing adjustment and realizing the function of stabilizing mechanical movement during zooming, reducing shaking, and achieving accurate positioning.

[0044] In summary, the positioning structure of this fast-focusing camera utilizes an image sensor 1, a lens module 2, a focusing mechanism 3, a lens 31, a connecting block 32, a slider 33, and a connecting mechanism 4. During use, the slider 33 moves under the influence of external forces, causing the connecting block 32 and the lens 31 to move as a whole. The lens 31 changes position along with the lens module 2, thus changing its focal length and achieving rapid focus adjustment. This allows the image sensor 1 to stably acquire images based on the lens module 2, reducing the shaking caused by the movement of the lens 31. It solves the problem of existing cameras easily causing lens shaking during focus adjustment due to mechanical movement, resulting in unclear image focus and time-consuming and labor-intensive repeated focus adjustments.
