[Prior Art] [0002] With the continuous development of digital technology, digital cameras have been widely used, especially in recent years, portable electronic devices such as mobile phones and PDAs (Personal Digital Assistants) are also rapidly increasing. With the development of performance and multi-functionality, the combination of digital cameras and these portable electronic devices has become the key to the development of mobile multimedia technology. A digital camera body combined with a portable electronic device requires a small volume and a simple structure, and therefore a fixed focus structure is often used, that is, the distance between the lens group and the image sensor remains unchanged. However, the digital camera module with fixed focus structure can only perform clear focus imaging on the scene within a certain distance range. The scene outside the range cannot be clearly imaged by the focusing mechanism. The digital camera with fixed focus structure can not To meet the consumer demand for high performance, the introduction of focusing mechanisms into portable electronic devices will have broad application prospects. [0003] Referring to FIG. 11 , Chinese Patent No. 92104988. 9 discloses an autofocus mechanism for a camera that utilizes an electromagnetic mechanism to realize an auto focus function. The autofocus mechanism 9 includes a lens 90, guiding arms 92a, 92b, guiding legs 94a, 94b, a coil spring 96, an electromagnetic mechanism 98 and a driving plate 99, and the guiding arms 92a, 92b are fixed to the annular portion of the lens 90. In one piece, the guiding struts 94a, 94b extend upward from the camera substrate (not shown), and the electromagnetic mechanism 98 is fixed to the camera substrate. Among them, the lens 9 is in the spiral 094137901

When the electromagnetic mechanism 98 is energized and the drive plate 99 depresses the guide arm 92a, the lens 90 is moved toward the camera substrate until it moves to the distant focus position. However, the above-mentioned focusing mechanism that realizes the focusing function by the electromagnetic principle has a complicated structure due to the use of components such as the electromagnetic mechanism 98, the driving plate 99, and the spring 96, and the effect is affected by the increase in the utilization frequency due to the aging of the spring. Focusing accuracy. [0004] Another conventional autofocus mechanism generally includes a distance sensor, a signal processing unit, a motor drive chip, and a motor. The distance sensor is disposed in a viewing window of the camera, and the distance can be detected. The distance between the object and the φ is processed and transmitted to the motor drive chip to drive the motor to drive the focus lens group by a gear such as a gear, and move to a designated position to complete the self-focusing. However, the autofocus mechanism is driven by a motor, and its volume and weight are large, which is inconvenient to be used in portable electronic devices such as mobile phones, and as the demand of consumers increases, in order to achieve higher performance, a general digital camera lens The lens has increased more than in the past, and its weight has increased compared with the past, and the transmission device also has certain difficulties in driving the lens group. On the other hand, the power consumption of the motor is large, and the power storage φ of the portable electronic device is limited, which will greatly shorten the use time of the portable electronic device and affect the application of its basic functions. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an autofocus digital camera module that is small in size, low in power consumption, and can be used in portable electronic devices such as mobile phones.

In addition, the lens and image sensing device may not be directly aligned, but may be indirectly aligned by other optical components such as mirror total reflection prisms, i.e., as long as the lens is optically aligned with the image sensing device. The digital camera module uses a voice coil actuator to drive the image sensor. First of all, the weight of the image sensor is much smaller than that of the lens, especially for high-end production. °, in order to achieve the corresponding high performance, it is often necessary to set a plurality of lenses, generally reaching 3 to 4 pieces 'this makes the weight of the lens will greatly increase the general motor is more and more difficult to drive its movement, but the image sensor of high-end products in quality Compared with the low ~ product, it is much smaller than the lens, and the image sensor does not need a rear seat, can be directly installed in the voice coil actuator, its weight will be further reduced 'that is, the inertia of the image sensor will be Far smaller than the lens, its φ motion shape I, easier to change, a little force can change its state, fast response, small hysteresis and low energy consumption. Secondly, the voice coil actuator is used to drive the image sensor, because the voice coil actuator directly converts the electric energy into the mechanical power required to drive the image sensor to move, no transmission machinery, and no wear of the transmission machinery, as long as the voice coil The input current can drive its movement. There is no mandatory voltage and current requirement. It can still work under low pressure. It has small volume and high energy utilization.
