Among them, the coil of the new type M2993〇5 patent case is set between the lens and the coil spring, that is, the coil. The yellow is on the periphery of the coil, causing the distance between the coil and the magnet to be relatively large to relatively reduce the electromagnetic action (electromagnetic force) generated between one; and the coil spring sleeve = outside the coil The circumference of the coil spring is relatively large, which affects the balance and stability of the coil spring. As can be seen from the above, the design of the lens module still further improves the space.

The T coil spring 70 can adopt a compression coil spring, and when the upper cover=the cover 10 is integrated into one body, the coil spring 70 can be compressed in a suitable manner, and presses the lens sleeve 50 relatively downward to make the lens Group 2 stops after the - telescopic stroke (below) dead point position 'and forms the far focus position; and the line. The head of the circle 80, the tail end can change the different electrodes and current, so as to match the magnetic iron 40 N , S pole generates forward/backward (up/down) electromagnetic force, thereby driving the front/rear (up/down) movement of the lens group 2 to perform a focusing operation; in the embodiment, the coil 80 and the magnet 4 The generator of the daytime electromagnetic force can choose to generate only the forward (upward) electromagnetic force, so that in the far focus position, the coil 80 can not pass current, so that the lens group 2 is not affected by the electromagnetic force and stays at the back (lower) dead point. Position (far focus position); when the focus action is to be performed, an appropriate amount of current is passed through the coil 80, thereby generating an appropriate amount of electromagnetic force to drive the lens group 2 to move forward (upward) to form a near focus state, and When the lens group 2 receives the electromagnetic force and the compression force of the coil spring 70 When balancing, the lens group ^ - stays in the adjusted position. Therefore, the lens group 2 is moved from the far focus to the near focus position by the far focus, and the electromagnetic force is applied, and the near focus position is backward (down) to the far focus. The position can be recovered by the coil spring 70 to achieve the near-focus adjustment effect. By using the circuit design, the lens group 2 can achieve the auto-focus type of the segmentless or only the far and near focus two-stage type. Compared with the conventional lens module, the present invention uses only one coil spring 70 to be sleeved on the annular groove 52 of the lens sleeve 50, and the four magnets 40 are respectively placed on the rectangular bottom cover. The fourth bracket 丨1 is inside, so the structure is interposed and the volume is reduced', which is advantageous for reducing the lens module 1; the coil Micture M317027 70 is sleeved on the annular groove 52 between the inner circumference of the coil 80 and the periphery of the lens 60. The coil 80 is located at the periphery of the coil spring 70, and the distance between the coil 80 and the four magnets 40 is relatively reduced, and the electromagnetic interaction between the coil go and the magnet can be improved; and the circular diameter of the coil spring 70 is also relatively reduced. It can improve the balance and stability of its spring force. The above are only the preferred embodiments of the present invention, and are merely illustrative and not limiting. It will be understood by those skilled in the art that many modifications and even equivalent changes can be made in the spirit and scope defined by the claims, but all of them will fall within the scope of protection of the present invention. 1 is a perspective view of an embodiment of the present invention. 2 is an exploded perspective view of FIG. 1.
