Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The existing optical image stabilization system used in the camera module of camera devices such as mobile phones mainly adopts lens moving technology, which detects the movement of the camera device through a gyroscope, and then uses voice coil motors, memory metals or piezoelectric materials, etc. The driving mechanism makes the lens move in the X and Y directions, and then realizes the compensation for the jitter in the X and Y directions. Generally, the existing lens is installed on the frame, and the frame is movably installed on the base of the camera module. The driving mechanism is connected between the frame and the base and corresponds to X, Y There will be multiple directional drive mechanisms, and the multiple drive mechanisms can be coordinated and controlled at the same time to drive the frame on the base in the X and Y directions, thereby realizing the compensation for the X and Y direction jitter. However, when the optical image stabilization system on the existing camera module works, multiple driving mechanisms need to be controlled at the same time, so the control is more difficult.

In response to the above-mentioned problems, the present application provides a lens module, which can be applied to camera modules of camera devices such as mobile phones and digital cameras. As shown in FIGS. 1 to 7, the lens module 100 includes a base 1, a sliding frame 2, a lens frame 3, a first driving part 41, a second driving part 42 and a lens 6.

The sliding frame 2 is slidably connected to the base 1 along a first direction, the lens frame 3 is slidably connected to the sliding frame 2 along a second direction, the lens 6 is connected to the lens frame 3, and the first direction and the second direction intersect. Since the frame 3 can slide along the second direction on the sliding frame 2, and the frame 3 can slide along the first direction with the sliding frame 2 on the base 1, the frame 3 has a first direction and a second direction. The sliding stroke in two directions, and then the lens 6 is driven by the frame 3 to realize the compensation of the jitter in the first direction and the second direction (as shown in Figure 4, Figure 6 and Figure 7, the base 1, the sliding frame 2, and the frame 3, respectively corresponding to the lens 6 is provided with a base avoidance port 15, a sliding frame avoidance port 25, and a frame avoidance port 37). Wherein, the specific connection mode between the frame 3 and the lens 6 may not be specifically limited. As shown in Figs. 2 and 4, in a specific embodiment, the frame 3 is provided with a mounting groove 31, and the lens 6 Installed at the installation slot 31.

And, because the first direction and the second direction intersect (the first direction and the second direction intersect means that the angle between the two is not 0° and 180°), then the first direction and the second direction jointly define The jitter in any direction in the plane can be decomposed into the jitter in the first direction and the jitter in the second direction, so as to realize the compensation for the jitter in any direction in the plane. For example, as shown in FIGS. 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. In this way, when the lens 6 is mounted on the frame 3, the sliding direction of the sliding frame 2 and the frame 3 is perpendicular to the optical axis direction of the lens 6, through the movement of the frame 3 in the first direction and the movement in the second direction. Compensation for the jitter in the first direction and the second direction is achieved, and the compensation for the jitter in the optical axis direction of the lens 6 is usually achieved through the automatic zoom system of the camera module. By setting the first direction to be perpendicular to the second direction, the movement in either direction of the movement in the first direction and the movement in the second direction of the frame 3 has no component in the other direction, so that the frame 3 is in The movement in the first direction and the movement in the second direction do not affect each other. It needs to be specifically noted here that the fact that the two are perpendicular in this application means that the angle between the two is 90° or approximately 90°.

The first driving member 41 is connected between the base 1 and the sliding frame 2 for driving the sliding frame 2 to slide on the base 1 along the first direction. The second driving member 42 is connected between the sliding frame 2 and the frame 3 for driving the frame 3 to slide on the sliding frame 2 along the second direction. The sliding frame 2 is driven in the first direction by the first driving member 41 to drive the frame 3 and the lens 6 in the first direction to realize the compensation of the jitter in the first direction, and the second driving member 42 is used in the second direction. The frame 3 and the lens 6 are driven in the second direction to compensate for the jitter in the second direction. In this way, a driving part is used to control the movement of the frame 3 in one direction, and the control in the two directions does not interfere with each other, so it is extremely Reduce the control difficulty. In order to avoid the situation that the driving force of a single driving member is insufficient, in a specific embodiment, the first driving member 41 includes two first sub-driving members, and the two ends of the sliding frame 2 in the direction perpendicular to the first direction Are respectively connected to the base 1 through two first sub-driving elements; and/or, the second driving element 42 includes two second sub-driving elements, and the two ends of the frame 3 in the direction perpendicular to the second direction pass through The two second sub-drivers are connected to the sliding frame 2. In this way, by increasing the number of the first driving member 41 and/or the second driving member 42, the driving force for the sliding frame 2 and the lens frame 3 can be correspondingly increased. It should be noted here that the direction perpendicular to the first direction and the direction perpendicular to the second direction in this application 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, then the direction perpendicular to the first direction is the second direction, and the direction perpendicular to the second direction is the first direction.

Wherein, the lens module 100 drives the sliding frame 2 and the lens frame 3 through the first driving member 41 and the second driving member 42 respectively. The first driving part 41 and the second driving part 42 may be a micro-electromechanical system. After the micro-electro-mechanical system is energized, the micro-electromechanical system can drive the sliding frame 2 and the mirror frame 3; the first driving part 41 and the second driving part 42 can also be Piezoelectric ceramic parts, the material of the piezoelectric ceramic parts is piezoelectric ceramics, using the piezoelectric effect of piezoelectric ceramics, the piezoelectric ceramic parts can produce expansion and contraction deformation after energizing, so as to drive the sliding frame through the expansion and contraction deformation of the piezoelectric ceramic parts 2 and frame 3; the first driving part 41 and the second driving part 42 can also be shape memory alloy parts, the material of the shape memory alloy parts is shape memory alloy, and the shape can be realized by changing the power supply current of the shape memory alloy parts The temperature change of the shape memory alloy piece causes the shape memory alloy piece to expand or contract to drive the sliding frame 2 and the frame 3 through the deformation of the shape memory alloy piece. Moreover, since the resistance value and length of the shape memory alloy piece are related, When the shape memory alloy part is working, the resistance value of the shape memory alloy part can be used to reflect the length of the shape memory alloy part, that is, the driving distance of the shape memory alloy part to the sliding frame 2 and the mirror frame 3 can be obtained, thereby forming a closed loop control , Improve control accuracy. When the first driving part 41 and the second driving part 42 are shape memory alloy parts, the shape memory alloy parts may be arranged in a strip shape, a linear shape or a block shape. The linear arrangement of the shape memory alloy means that the extending direction of the shape memory alloy 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 both It is a linear arrangement (as shown in Figure 2, the base 1, the sliding frame 2 and the mirror frame 3 are provided with a terminal 43, and the two ends of the first driving member 41 are respectively connected to the terminal 43 and the sliding frame on the base 1. The terminal 43 on the frame 2 and the two ends of the second driver 42 are respectively connected to the terminal 43 on the frame 3 and the terminal 43 on the sliding frame 2. By setting the terminal 43, it is convenient to install the first driver 41 And the second driving member 42), wherein: the extending direction of the first driving member 41 is obliquely arranged with respect to the first direction; and/or, the extending direction of the second driving member 42 is obliquely arranged with respect to the second direction. In this way, by obliquely setting the first driving member 41 with respect to the sliding direction of the sliding frame 2 and/or setting the second driving member 42 obliquely with respect to the sliding direction of the frame 3, the shape memory alloy member is arranged obliquely with respect to the non-inclined shape memory alloy member. When the shape memory alloy changes per unit length, the sliding distance of the lens 6 becomes shorter, which is beneficial to improve the control accuracy of the sliding distance of the lens 6.

The present application drives the sliding frame 2 in the first direction by the first driving member 41 to drive the frame 3 and the lens 6 in the first direction to realize the compensation of the jitter in the first direction, and the second driving member 42 in the first direction The frame 3 and the lens 6 are driven in the second direction to compensate for the jitter in the second direction. Because the lens module 100 controls the movement of the frame 3 in one direction through a driver, the control in two directions There is no interference with each other, so the control difficulty is greatly reduced, and since the frame 3 adopts a composite motion structure, the rigidity of the lens module 100 can be improved.

The frame 3 is slidably connected to the sliding frame 2 along the second direction. There are no special requirements for the specific styles of the sliding frame 2 and the frame 3, as shown in Figure 1, Figure 5 and Figure 6, in a specific embodiment The sliding frame 2 is provided with a first guide rod 21 and a second guide rod 22 extending in the second direction in parallel, and the frame 3 is connected to both the first guide rod 21 and the second guide rod 22 (for example, the frame 3 It may be that the first guide rod 21 and the second guide rod 22 are respectively connected at the two ends in the direction perpendicular to the second direction, which facilitates the smooth installation of the frame 3). In this way, by arranging the first guide rod 21 and the second guide rod 22 in parallel to support the lens frame 3, it is beneficial for the lens frame 3 to slide smoothly on the sliding frame 2, and the rigidity of the lens module 100 is improved.

Further, as shown in FIGS. 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, and the first guide The rod 21 passes through the frame 3 from the first perforation 32 and forms a guiding fit with the first perforation 32 in the second direction. The second guide rod 22 passes through the frame 3 from the second perforation 33 and connects with the second perforation 33. The perforation 33 forms a guiding fit in the second direction. In this way, the arrangement of the first through hole 32 and the second through hole 33 can not only realize the sliding guide of the frame 3 in the second direction, but also realize the installation and positioning of the frame 3.

In order to avoid over-positioning of the frame 3, as shown in FIGS. 3 and 5, in a specific embodiment, the cross-sectional shape of the first guide rod 21 matches the cross-sectional shape of the first perforation 32. The second guide rod 22 and the second perforation 33 have a movable gap reserved in the direction perpendicular to the second direction. The cross-sectional shape of the first guide rod 21 matches the cross-sectional shape of the first perforation 32, which means that the cross-sectional shape of the first guide rod 21 is consistent with that of the first guide rod 21 without affecting the sliding of the first guide rod 21 in the second direction. The cross-sectional shape of the first perforation 32 is the same or similar, and the size is the same or similar. For example, the cross-sectional shape of the first guide rod 21 and the cross-sectional shape of the first perforation 32 are both round or square with the same size, so that the first perforation The limiting effect of the inner side wall of 32 on the first guide rod 21 can achieve the effect of limiting the position of the frame 3 in directions other than the second direction. The second guide rod 22 and the second perforation 33 have a movable gap in the direction perpendicular to the second direction, which means that the size of the second perforation 33 in the direction perpendicular to the second direction is larger than that of the second guide rod 22 in the direction perpendicular to the second direction. The dimension in the direction perpendicular to the second direction makes the installation position of the second guide rod 22 adjustable in the direction perpendicular to the second direction. For example, the second guide rod 22 is a round rod, and the second perforation 33 is rectangular. The hole arrangement, through the second guide rod 22 and the second perforation 33 in the direction perpendicular to the second direction, a movable gap is reserved, which can avoid over-positioning and facilitate the installation of the frame 3.
