The light-emitting element 82 can be fixed to the lens base (9) by glue bonding, and is located between the second lens module 5G and the sensing member (9) for cutting off from the light-receiving hole 211 and sequentially passing through the first lens.

H cut-off film or infrared cut-off zoom lens module (10) during use, piezoelectric due to, there is an inverse piezoelectric effect, when the voltage is applied to the piezoelectric ceramic piece = piece 3!: can convert electrical energy into machinery Can, in order to produce mechanical vibration, 兖: Ϊι Tao / 2 3 two surface produces ultrasonic waves, and along the optical axis direction on the piezoelectric ceramic parts and surface. Since the piezoelectric ceramic element 31 and the sliding member 32 are closely matched with each other, the mechanical vibration of the piezoelectric element 31 causes the piezoelectric element and the disk (four) member 32 to be pressed against each other, thereby; 'And through the mechanical friction: = electric ceramics piece 31 moves along the line of light. At this time, the first lens module 4 () of 32 also linearly moves along the direction of the optical axis of the slider. Because the second end portion 22 of the first pole tube 2 is closed, the first lens 2 is fixed to the mirror lens unit 40 and moves linearly along the optical axis of the zoom lens module 100 with the slider 200827905 32. During the process, the distance between the first lens module 40 and the second lens module 50 changes accordingly, thereby changing the framing focal length to achieve zooming. In addition, referring to FIG. 2, the zoom lens module 100 further includes a third lens module 90. The third lens module 90 can be fixed to the first end portion 21 of the lens barrel 20 by a glue bonding method, and is located between the light entrance hole 211 and the first lens module 40, so that the light enters the zoom lens through the light entrance hole 211. After the module 100, the third lens module 90, the first lens module 40 and the second lens module 50 can be sequentially passed through. The third lens module 90 includes at least one third lens 92 received in the lens barrel 20. The third lens module 90 can be a composite lens composed of two third lenses 92, and the resolution can be improved by using a plurality of third lenses 92. The third lens 92 can be made of glass or plastic. Preferably, the surface of the third lens 92 can be coated with a layer of anti-reflection film, and the anti-reflection effect of the anti-reflection film can increase the transmittance of the lens, thereby further improving the imaging brightness of the zoom lens module 100. During use of the zoom lens module 100, the piezoelectric ceramic member 31 drives the slider 32 to linearly move in the optical axis direction on the piezoelectric ceramic member 31. At this time, the first lens module 40 fixed to the slider 32 also linearly moves along the optical axis direction of the zoom lens module 100 along with the slider 32. Since the second lens module 50 is fixed to the second end portion 22 of the lens barrel 20, the third lens module 90 is fixed to the first end portion 21 of the lens barrel 20, so that the first lens module 40 follows the sliding member. During the linear movement of the zoom lens module 100 along the optical axis direction, the distance between the first lens module 40 and the second lens module 50 and the third lens module 90 respectively changes, thereby changing the framing focal length. And achieve zoom. 11 200827905 Steps to increase the zoom lens In this embodiment, a plurality of lens modules are used to enter a module resolution. > 〗 3 The technical solution of the second embodiment provides a variable lens module, which is provided with the zoom lens of the embodiment - (the same as 1 f lies in the first lens mode of the zoom lens module) The group 40 includes an endoscope 44 and at least one first lens 42 received in the inner lens barrel 44. The first lens 42 can be fixed in the endoscope barrel by dispensing glue. The outer diameter of the endoscope 坷 44 is equal to The inner diameter of the sliding member 32 is such that the sliding member is sleeved on the outer surface of the inner lens barrel 44. The inner lens barrel 44 can be imaginarily matched with the sliding member through a thread, or can be matched by other means. The advantages of 1〇〇 and 2〇〇 are that the zoom lens modules 100 and 200 each use a piezoelectric ceramic member and a sliding member to form a piezoelectric 'ceramic motor, which directly drives the sliding member in the middle of the lens barrel. The optical axis moves linearly to drive the first lens module fixed to the sliding member=the second lens module fixed to the lens barrel moves along the optical axis, thereby changing the framing focal length and realizing the zoom function, thereby simplifying the zoom lens mode Group structure, effectively reducing the size of the zoom lens module, In summary, the present invention meets the requirements of the invention patent, and the patent application is filed according to law.
