Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the specific embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The conventional optical image stabilization system applied to camera modules of mobile phones and other camera devices mainly adopts a lens moving technology, detects the movement of the camera device through a gyroscope, and then makes a lens move in X, Y direction by using driving mechanisms such as a voice coil motor, memory metal or piezoelectric material and the like, so as to realize compensation for X, Y direction shake. Generally, the existing lens is mounted on a lens frame, the lens frame is movably mounted on a base of a camera module, a plurality of driving mechanisms are arranged between the lens frame and the base, and the driving mechanisms corresponding to X, Y directions are coordinated and controlled simultaneously to drive the lens frame in X, Y directions on the base, so that X, Y direction shake compensation is realized. However, when the optical image stabilization system of the existing camera module works, a plurality of driving mechanisms need to be controlled simultaneously, so that the control difficulty is high.

In view of the above problems, the present application provides a lens module that can be applied to a camera module of a camera device such as a mobile phone or a digital camera. As shown in fig. 1 to 7, the lens module 100 includes a base 1, a sliding frame 2, a frame 3, a first driving member 41, a second driving member 42, and a lens 6.

The carriage 2 is slidably coupled to the base 1 in a first direction, the frame 3 is slidably coupled to the carriage 2 in a second direction, and the lens 6 is coupled to the frame 3 in a direction that intersects the second direction. Because the mirror holder 3 can slide along the second direction on the carriage 2, and the mirror holder 3 can slide along the first direction on the base 1 along with the carriage 2, make the mirror holder 3 have the ascending slip stroke in first direction and second direction like this, and then drive lens 6 through the mirror holder 3 and realize the compensation to the shake of first direction and second direction (as shown in fig. 4, fig. 6 and fig. 7, base 1, carriage 2, mirror holder 3 correspond lens 6 respectively and are provided with base dodge mouth 15, carriage dodge mouth 25, mirror holder dodge mouth 37). As shown in fig. 2 and 4, in a specific embodiment, a mounting groove 31 is formed on the frame 3, and the lens 6 is mounted at the mounting groove 31.

And, since the first direction intersects the second direction (the intersection of the first direction and the second direction means that the angle therebetween is not 0 ° or 180 °), the jitter in any direction within a plane defined by the first direction and the second direction can be decomposed into the jitter in the first direction and the jitter in the second direction, so as to compensate for the jitter in any direction within the plane. For example, as shown in fig. 1 and 2, in a specific embodiment, the first direction and the second direction are both perpendicular to the optical axis direction of the lens, and the first direction is perpendicular to the second direction. When the lens 6 is mounted on the frame 3, the sliding directions of the sliding frame 2 and the frame 3 are both perpendicular to the optical axis direction of the lens 6, and the shake compensation in the first direction and the shake compensation in the second direction are realized through the movement of the frame 3 in the first direction and the movement in the second direction, and usually, the shake compensation in the optical axis direction of the lens 6 is realized through an automatic zoom system of a camera module. By arranging the first direction to be perpendicular to the second direction, there is no component in either one of the movement of the mirror holder 3 in the first direction and the movement of the mirror holder 3 in the second direction in the other direction, so that the movement of the mirror holder 3 in the first direction and the movement of the mirror holder 3 in the second direction do not affect each other. It should be noted that, in the present application, the two are perpendicular, which means that the included angle between the two is 90 ° or approximately 90 °.

The first drive member 41 is connected between the base 1 and the carriage 2 for driving the carriage 2 to slide on the base 1 in a first direction. A second drive member 42 is connected between the carriage 2 and the frame 3 for driving the frame 3 to slide on the carriage 2 in a second direction. The sliding frame 2 is driven by the first driving part 41 in the first direction to drive the spectacle frame 3 and the lens 6 in the first direction, so that the shake compensation in the first direction is realized, and the spectacle frame 3 and the lens 6 are driven by the second driving part 42 in the second direction, so that the shake compensation in the second direction is realized, so that the movement of the spectacle frame 3 in one direction is controlled by one driving part, the control in the two directions is not interfered with each other, and the control difficulty is greatly reduced. In order to avoid the situation that the driving force of the single driving member is insufficient, in a specific embodiment, the first driving member 41 includes two first sub-driving members, and both ends of the carriage 2 in the direction perpendicular to the first direction are respectively connected to the base 1 through the two first sub-driving members; and/or the second driving member 42 comprises two second sub driving members, and both ends of the lens frame 3 in the direction perpendicular to the second direction are respectively connected to the sliding frame 2 through the two second sub driving members. By increasing the number of the first driving unit 41 and/or the second driving unit 42 in this way, the driving force for the carriage 2 and the lens holder 3 can be correspondingly increased. It should be noted that, in the present application, a direction perpendicular to the first direction and a direction perpendicular to the second direction both refer to a direction located in a plane defined by the first direction and the second direction, for example, in a specific embodiment, the first direction and the second direction are perpendicular, and then the direction perpendicular to the first direction is the second direction, and the direction perpendicular to the second direction is the first direction.

The lens module 100 drives the sliding frame 2 and the lens holder 3 through the first driving member 41 and the second driving member 42, respectively. The first drive 41 and the second drive 42 can be mems, which can drive the carriage 2 and the frame 3 after the mems is powered; the first driving member 41 and the second driving member 42 may also be piezoelectric ceramic members, the piezoelectric ceramic members are made of piezoelectric ceramics, and the piezoelectric ceramic members can generate telescopic deformation after being electrified by utilizing the piezoelectric effect of the piezoelectric ceramics, so that the sliding frame 2 and the mirror frame 3 are driven by the telescopic deformation of the piezoelectric ceramic members; the first driving member 41 and the second driving member 42 may also be a shape memory alloy member, the shape memory alloy member is made of a shape memory alloy, the temperature change of the shape memory alloy member is realized by changing the magnitude of the supply current of the shape memory alloy member, so that the shape memory alloy member expands or contracts, and the sliding frame 2 and the mirror frame 3 are driven by the deformation of the shape memory alloy member, and further, since the resistance value and the length of the shape memory alloy member are related, when the shape memory alloy member works, the length of the shape memory alloy member can be reflected by the resistance value change of the shape memory alloy member, i.e., the driving distance of the shape memory alloy member to the sliding frame 2 and the mirror frame 3 can be obtained, thereby forming closed-loop control and improving the control accuracy. When the first driving member 41 and the second driving member 42 are shape memory alloy members, the shape memory alloy members may be arranged in a shape of a strip, a line, a block, or the like. Wherein, the shape memory alloy member is arranged linearly means that the extending direction of the shape memory alloy member is a straight line, for example, as shown in fig. 1, in a specific embodiment, the first driving member 41 and the second driving member 42 are arranged linearly (as shown in fig. 2, the base 1, the sliding frame 2 and the lens frame 3 are provided with the terminals 43, both ends of the first driving member 41 are respectively connected to the terminals 43 on the base 1 and the terminals 43 on the sliding frame 2, both ends of the second driving member 42 are respectively connected to the terminals 43 on the lens frame 3 and the terminals 43 on the sliding frame 2, and the first driving member 41 and the second driving member 42 are conveniently installed by arranging the terminals 43), wherein: the extending direction of the first driving member 41 is inclined with respect to the first direction; and/or the direction of extension of the second drive member 42 is arranged obliquely with respect to the second direction. By thus providing the first drive member 41 inclined with respect to the sliding direction of the carriage 2 and/or the second drive member 42 inclined with respect to the sliding direction of the eyeglass frame 3, the sliding distance of the lens 6 becomes shorter when the amount of change per unit length of the shape memory alloy member inclined with respect to the shape memory alloy member not inclined is generated, which is advantageous in improving the accuracy of controlling the sliding distance of the lens 6.

This application drives the carriage 2 through first drive 41 in the first direction, with drive mirror holder 3 and lens 6 in the first direction, realize the compensation to the shake of first direction, and drive mirror holder 3 and lens 6 in the second direction through second drive 42, realize the compensation to the shake of second direction, because lens module 100 controls the motion of mirror holder 3 in an orientation through a drive, control in two directions is mutual noninterference, so greatly reduced the control degree of difficulty, and, because the mirror holder 3 adopts the compound motion structure, can improve lens module 100's rigidity like this.

By arranging the first guide bar 21 and the second guide bar 22 in parallel to support the lens frame 3, the lens frame 3 can smoothly slide on the sliding frame 2, and the rigidity of the lens module 100 is improved.

Further, as shown in fig. 3 and 5, in a specific embodiment, the frame 3 is provided with a first through hole 32 and a second through hole 33 corresponding to the first guide rod 21 and the second guide rod 22, the first guide rod 21 passes through the frame 3 from the first through hole 32 and forms a guiding fit with the first through hole 32 in the second direction, and the second guide rod 22 passes through the frame 3 from the second through hole 33 and forms a guiding fit with the second through hole 33 in the second direction. In this way, by the arrangement of the first through hole 32 and the second through hole 33, not only the sliding guide of the lens holder 3 in the second direction can be realized, but also the mounting and positioning of the lens holder 3 can be realized.

To avoid over-positioning the frame 3, in a particular embodiment, as shown in fig. 3 and 5, the first guide 21 has a cross-section adapted to the cross-section of the first through-hole 32, and the second guide 22 and the second through-hole 33 have a clearance in the direction perpendicular to the second direction. The cross-sectional shape of the first guide rod 21 is matched with the cross-sectional shape of the first through hole 32, which means that the cross-sectional shape of the first guide rod 21 is the same as or similar to the cross-sectional shape of the first through hole 32 and has the same or similar size on the premise that the sliding of the first guide rod 21 in the second direction is not influenced, for example, the cross-sectional shape of the first guide rod 21 and the cross-sectional shape of the first through hole 32 are both circular or square with the same size, so that the effect of limiting the spectacle frame 3 in directions other than the second direction can be achieved by the limiting effect of the inner side wall of the first through hole 32 on the first guide rod 21. The second guide rod 22 and the second through hole 33 are provided with a movable gap in the direction perpendicular to the second direction, which means that the size of the second through hole 33 in the direction perpendicular to the second direction is larger than the size of the second guide rod 22 in the direction perpendicular to the second direction, so that the installation position of the second guide rod 22 can be adjusted in the direction perpendicular to the second direction, for example, the second guide rod 22 is a round rod, the second through hole 33 is a rectangular hole, and the movable gap is provided in the direction perpendicular to the second direction through the second guide rod 22 and the second through hole 33, which can avoid the over-positioning condition and is convenient for installing the lens frame 3.
