Field of the Invention The present invention relates to a lens module, in particular, a zoom device and a lens module which are simple in structure and small in size. [Prior Art] With the development of camera technology, camera modules have been widely used in various types of camera devices. The combination of camera modules and various portable electronic devices such as mobile phones, video cameras, computers, etc. The green of consumers. Cameras are usually required to function for images with different magnifications (see Z_Lens Systems _ Asphedcal ρ1_ Lens ^ Consumer Electronics, IEEE Transactions on Volum CE-33' Issue 3, AUg. 1987 Page(s): 256 - 266 There are two ways to achieve the camera's zoom function: optical zoom and digital zoom. The optical zoom relies on the structure of the optical lens itself to effect the change, that is, the line overdrive device drives the lens movement within the lens or manually rotates the lens barrel to move the film to enlarge or reduce the captured scene. Zoom The lens has a relatively large volume, so there is a lot of room for the fun. -The internal mirror U image sensor is limited to the volume. The limited space of H ^ ° in the fuselage limits the movement of the lens and the sensation of the image. Therefore, it is a chicken in the hand, so the car is a gentleman. It is more difficult to realize optical zoom in the middle, so most mobile phones use m-k /K enemy code to fix the image. The so-called digital zoom is actually a large one, and the picture of the electronic image of the pjy gang-Turi on the image sensor is enlarged by the camera inside the camera to achieve the purpose of magnifying the image. In the same way, the scenes taken after the digital zoom are magnified:: Object: 'f focus will not drop. Accuracy of the hall and the object - The zoom lens is zoomed by changing the distance between the horses and the moon. Constructing the mirror gear set mechanism makes the drive mechanism more complicated and difficult to manufacture. Motor, [Summary of the Invention] It is also necessary to provide a squeezing device and a lens module which are simple in structure and small in size. The m-type zoom device includes a first lens, a second lens, and a hydraulic pressure. The liquid house device is disposed between the first lens and the second lens to change the distance between the first film and the second lens. The lens moves in a direction away from or close to the second lens. Under the action of the -= head module, including at least the first lens, the second lens, the hydraulic clothing and the lens of the Gu Nadi-lens, the second lens. A hydraulic device is disposed between the first lens and the second lens to change the distance between the first lens and the second lens. The first lens moves toward or away from the second lens by the hydraulic device. Compared with the prior art, the zoom device of the embodiment of the present invention changes the distance between the first lens and the second lens by hydraulic wear, and the lenses of different distances have different focal lengths, thereby realizing the zoom function of the lens module. . The zooming and splitting of the embodiment of the present invention uses a hydraulic device to change the distance between the lenses. Therefore, the zoom device has a simple structure and a small volume, and the lens module using the zoom device is also simple in structure and small in size. [Embodiment] The present invention will be further described in detail with reference to the accompanying drawings, and the second embodiment of the present invention includes a first lens U, a second lens 12, and a liquid friction device 13, = 14, image sensor 15, holder 16 and mirror holder 17.
