Therefore, the lens in the lens barrel is opposite to the imaging device. The image sensor moves up and down to achieve focus adjustment. However, the lens barrel of the existing lens module adopts a straight tube type = and the straight tube type structure has a maximum outer diameter limited to the brother close to the image sensor, when the voice coil motor is sleeved on the straight barrel This causes the bulk of the overall imaging device to become bulky.

The outer diameter of the top of the lens is smaller than the outer diameter of the bottom of the lens. The top of the lens is sleeved in the actuator. Fixed on the top surface of the lens holder 2, the 5 Xuan actuator is used to drive the lens to move away from or close to the image sensor. ❹ Compared with the prior art, the lens includes a lens top and a top of the lens. At the bottom of the lens, the outer diameter of the top of the lens is smaller than the outer diameter of the bottom of the lens, and the actuator is sleeved on the top of the lens with a relatively small outer diameter to drive the lens to move away from or close to the image sensor.

Referring to FIG. 2 and FIG. 4 together, the actuator 40 includes a top surface 334 11 201007340 that is carried on the lens holder 33. A positioning portion is disposed on the lower surface 432. In the embodiment, the positioning portion is at least one positioning post 434. The positioning post 434 is inserted into the receiving hole 336 of the top surface 334 of the lens holder 33 by an interference fit so that the actuator 40 is fixed to the top surface 334 of the lens holder 33. The lower surface 432 of the actuator 40 is disposed around the periphery of the positioning post 434 with a second receiving groove 438. The second receiving groove 438 is opposite to the first receiving groove 337 of the top surface 334 of the lens holder 33. Through. The image forming apparatus 100 further includes a colloid 439 which is respectively coated in the first accommodating groove 337 and the second accommodating groove 438 of the actuator 40 。. The holding strength of the actuator 40 and the top surface 334 of the mirror holder 33 can be enhanced. In the actual application, at least one accommodating groove is formed in the periphery of the top surface 334 of the lens holder 33. The actuator 40 is fixed on the accommodating groove by the glue 439. The actuator 40 is fixed to the top surface 334 of the lens holder 33. It is not limited to this embodiment. The fixing component 44 is fixed in the cavity 412. The fixing member 44 includes a fixing frame 442 and four permanent magnets 444 which are sleeved in the fixing frame 442. The fixing frame 442 is a frame body having a rectangular tubular shape. The four square sidewalls 445 of the mounting bracket 442 define a first receiving cavity 443 for receiving the movable component 42. A magnetic portion 447 is disposed on each of the square side walls 445 for receiving the permanent magnets 444. In the embodiment, the four corner positions of the upper end surface and the lower end surface of the fixing frame 442 respectively extend to form a protrusion 446 for positioning the fixing frame 442 and the elastic piece 47. The movable component 42 is sleeved in the first accommodating cavity 443 of the fixing component 44. The movable element 42 has a loading cylinder 421 and a coil 424 wound around the outer wall 12 201007340 • of the loading cylinder 421. The coil 424 is disposed opposite the permanent magnet 444. The cartridge 421 includes a second receiving cavity 426 having a generally cylindrical shape. The outer side wall of the second accommodating cavity 426 has an internal thread 425 corresponding to the outer lens portion 312 of the lens top portion 312. The outer lens thread 312 of the lens top 312 and the inner thread 425 of the movable component 42 are screwed into the second accommodating cavity 426. In actual application, the lens top 312 can also be fixed to the movable member 42 by gluing, and is not limited to the embodiment. The two elastic pieces 47 are disposed in the cavity 412, and the fixing element 44 and the movable element 42 are disposed between the two elastic pieces 47. In the embodiment, the elastic piece 47 has a square structure, and the four corner positions are respectively provided with through holes 472 corresponding to the protrusions 446 of the fixing frame 442.

In practical applications, as long as the protrusions 446 cooperate with the through holes 472, the two elastic pieces 47 and the fixing frame 442 can be positioned and fixed. It can be understood that the number of the protrusions 446 10 may also be two, three or more, and is not limited to the embodiment. When assembling together with FIG. 1 and FIG. 4, the internal thread 425 in the second receiving cavity 426 of the actuator 40 is first screwed with the external thread 3121 of the lens top 312 to make the actuator 40 is integrally connected to the lens barrel 31. The lens holder 33 is fixed to the bearing surface 22 of the substrate 20, and the actuator 40 is fixed to the top surface 334 of the lens holder 33. In use, the coil 424 is energized such that a Lorentz force is generated between the coil 424 and the permanent magnet 444, causing the movable assembly 42 to move axially up and down relative to the stationary assembly 44. Since the lens top 13 201007340 portion 312 is sleeved in the second accommodating cavity 426 of the movable component 42 , the movable component 42 can be moved up and down relative to the fixing component 44 to make the lens group in the lens 30 . 32 moves toward or away from the image sensor to achieve the focus. After the power is turned off, the two elastic pieces 47 are restored to deform, and the movable assembly 42 is reset. Fig. 5 is a schematic view showing an image forming apparatus 2 according to a second embodiment of the present invention. The structure of the imaging module 200 of the second embodiment is substantially the same as that of the imaging device 100 of the first embodiment.
