Description

Technical Field

[0001] A camera lens driving device, particularly a camera lens driving device capable of zooming and focusing. Background Technology

[0002] As camera lens sizes shrink, and to achieve zooming or focusing within limited space, current camera lenses utilize voice coil motors (VCMs) for automatic focusing or zooming. Existing voice coil motors use magnets and coils for drive, requiring a relatively large amount of space, thus making it difficult to further miniaturize electronic products using voice coil motors. Utility Model Content

[0003] In view of this, in some embodiments, a camera lens driving device is provided, which includes a frame, a first lens mount, a second lens mount, and an actuation component; the frame has two guide rails on its two sides respectively; the first lens mount is slidably disposed on one side of the two guide rails, and the second lens mount is slidably disposed on the other side of the two guide rails; the actuation component includes a first actuation component and a second actuation component; the first actuation component is disposed on the frame and clamped between the first lens mount and the second lens mount, and is used to move the first lens mount and the second lens mount; the second actuation component is disposed on the second lens mount and is used to generate a driving force; in response to the driving force being greater than the maximum static friction force between the first actuation component and the second lens mount, the second actuation component drives the second lens mount to move relative to the first lens mount.

[0004] In some embodiments, the first lens mount has a first clamping member, which has a first clamping portion; the second lens mount has a second clamping member, which has a second clamping portion and a third clamping portion. The first actuating component is clamped in the first clamping portion, the second clamping portion, and the third clamping portion.

[0005] In some embodiments, the first actuation component includes a friction rod and a piezoelectric component, the first piezoelectric component being connected to one end of the friction rod, and a first clamping portion being located between the piezoelectric component and the second clamping portion.

[0006] In some embodiments, the second actuation component includes a traveling wave drive; the traveling wave drive is fixed to the second mirror mount and has a friction element that contacts a friction rod; the traveling wave drive is used to actuate the friction element to drive the friction element to generate a driving force on the friction rod in the direction corresponding to the traveling wave.

[0007] In some embodiments, the first clamping member and the second clamping member each have two clamping arms.

[0008] In some embodiments, the first actuation component further includes an elastic element connected to the first piezoelectric component, the elastic element generating a corresponding deformation in response to the actuation of the first piezoelectric component.

[0009] In some embodiments, the two guide rails include a first ball set and a second ball set, the first ball set being located on one side of the frame and the second ball set being located on the other side of the frame. The first and second mirror mounts slide on these first and second ball sets.

[0010] In some embodiments, the camera lens driving device further includes a controller. The controller is electrically connected to the first actuation component and the second actuation component, and is used to generate a first control signal and a second control signal; the first actuation component generates a first movement according to the first control signal; and the second actuation component generates a second movement according to the second control signal.

[0011] In some embodiments, the two sides of the first mirror mount and the two guide rails are magnetically attracted to slide on the two guide rails; the two sides of the second mirror mount and the two guide rails are magnetically attracted to slide on the two guide rails.

[0012] In some embodiments, the first mirror mount has a first slide groove and a second slide groove on each of its two sides. The first slide groove is slidably disposed on one of the two guide rails, and the second slide groove is slidably disposed on the other of the two guide rails. The first slide groove is one of a U-shape and a V-shape, and the second slide groove is the other of a U-shape and a V-shape.

[0013] In summary, in zoom mode, the camera lens driving device moves the first and second lens mounts by means of the frictional force between them exerted by the first actuation component. In focus mode, the second actuation component generates a driving force on the first actuation component, which, when greater than the maximum static frictional force exerted by the first actuation component on the second lens mount, moves the second lens mount relative to the first lens mount. Thus, the camera lens driving device can perform precise zoom or focus movements. In some embodiments, the first and / or second actuation components include piezoelectric components, which can move the first and / or second lens mounts by means of deformation, thereby increasing the moving distance of the first or second lens mount.

[0061] L1: Camera optical axis Detailed Implementation

[0062] In some embodiments, such as Figure 1 and Figure 2As shown, the camera lens driving device 100 includes a frame 102, a first lens mount 104, a second lens mount 106, and an actuation assembly 108. The frame 102 has a guide rail (110a, 110b) on each side. The first lens mount 104 is slidably mounted on one side of the two guide rails (110a, 110b). The second lens mount 106 is slidably mounted on the other side of the two guide rails (110a, 110b). The actuation assembly 108 is used to drive the first lens mount 104 and / or the second lens mount 106 to move along the two guide rails (110a, 110b).

[0063] The first lens mount 104 and the second lens mount 106 can each support and assemble an optical component (e.g., a convex lens or a concave lens). The actuation component 108 can move the positions of the first lens mount 104 and the second lens mount 106 to perform focusing or zooming. It should be noted that the two guide rails (110a, 110b) are respectively parallel to a camera optical axis L1 of the optical component (e.g., ...). Figure 1 The optical axis L1 is parallel to the X-axis. The camera optical axis L1 can refer to the axis passing through the center point of the optical component (lens). Here, the guide rails (110a, 110b) guide the movement of the first lens mount 104 and the second lens mount 106, maintaining their angle and orientation parallel to the camera optical axis L1, to achieve precise focusing or zooming.

[0064] The actuation assembly 108 includes a first actuation assembly 112 and a second actuation assembly 114. The first actuation assembly 112 is disposed on the frame 102 and clamped between the first lens mount 104 and the second lens mount 106. The first actuation assembly 112 is used to move the first lens mount 104 and the second lens mount 106. The second actuation assembly 114 is disposed on the second lens mount 106. The second actuation assembly 114 is used to generate a driving force on the first actuation assembly 112. In response to the driving force being greater than a maximum static friction force between the first actuation assembly 112 and the second lens mount 106, the second actuation assembly 114 drives the second lens mount 106 to move relative to the first lens mount 104. Taking zoom as an example, as... Figure 3 As shown, the actuation component 108 can actuate the first actuation component 112, causing the first actuation component 112 to simultaneously drive the first lens mount 104 and the second lens mount 106 to move relative to the frame 102 (described in detail later) to perform zooming. Taking focusing as an example again, as... Figure 4 As shown, the actuation component 108 can actuate the second actuation component 114, causing the first lens mount 104 to remain stationary relative to the frame 102, while the second actuation component 114 drives the second lens mount 106 to move relative to the frame 102 (described in detail later) for focusing.

[0065] In some embodiments, the first actuation component 112 and / or the second actuation component 114 are input with a control signal (e.g., a voltage signal), which can drive the first actuation component 112 and / or the second actuation component 114 to generate movement (e.g., expansion, contraction, or oscillation). This movement allows the first actuation component 112 or the second actuation component 114 to move the first mirror mount 104 or the second mirror mount 106, respectively.

[0066] The first actuation component 112 generates static friction forces on both the first mirror mount 104 and the second mirror mount 106. For example, the first actuation component 112 has a first static friction force with the first mirror mount 104, and a second static friction force (i.e., the maximum static friction force) with the second mirror mount 106. The second actuation component 114 can perform an oscillating motion on the first actuation component 112 to generate a driving force on the first actuation component 112. Figure 3 As shown, in zoom mode, the first actuation component 112 can simultaneously move the first lens mount 104 and the second lens mount 106. The first lens mount 104 and the second lens mount 106 can move simultaneously while maintaining a preset distance (the preset distance can correspond to the focal length parameter that the camera lens drive device 100 wants to adjust). Figure 4 As shown, in focus mode, the second actuation component 114 is actuated to generate a driving force on the first actuation component 112. When this driving force is greater than the second static friction force, the second lens mount 106 can move relative to the first lens mount 104 by means of this driving force. It should be noted that since the first actuation component 112 is disposed on the frame 102, the second actuation component 114 applies a driving force to the first actuation component 112 without interfering with the first actuation component 112. Thus, when the second lens mount 106 moves, the first lens mount 104 can remain in the position of the frame 102.

[0067] The camera lens drive device 100 utilizes the static friction force of the first actuation component 112 on the first lens mount 104 and the second lens mount 106 to simultaneously drive both the first lens mount 104 and the second lens mount 106. Furthermore, by utilizing the design that the driving force generated by the second actuation component 114 on the first actuation component 112 is greater than the second static friction force, the second lens mount 106 can be moved independently. Therefore, the camera lens drive device 100 can perform precise zooming or focusing.

[0068] In some embodiments, such as Figure 1 As shown, the first mirror mount 104 has a first clamping member 116, and the first clamping member 116 has a first clamping portion 118. The second mirror mount 106 has a second clamping member 120, and the second clamping member 120 has a second clamping portion 122 and a third clamping portion 124. The first actuating assembly 112 is clamped in the first clamping portion 118, the second clamping portion 122 and the third clamping portion 124.

[0069] In some embodiments, such as Figure 1 As shown, the first actuation assembly 112 includes a friction rod 126 and a piezoelectric assembly 128. One side of the piezoelectric assembly 128 is connected to the frame 102, and the other side is connected to the friction rod 126. When the first actuation assembly 112 is not actuated, a first static friction force is generated between the friction rod 126 and the first clamping portion 118, and a second static friction force is generated between the friction rod 126 and the second clamping portion 122 and the third clamping portion 124. The piezoelectric assembly 128 can be a piezoelectric ceramic, a piezoelectric transistor, or a piezoelectric film (e.g., polyvinylidene fluoride). When a control signal (described later) is given to the piezoelectric assembly 128, the piezoelectric assembly 128 can contract and expand to drive the friction rod 126 to move axially. It should be noted that when the friction rod 126 is driven by the piezoelectric assembly 128, the friction rod 126 can drive the first mirror mount 104 with the first static friction force and the second mirror mount 106 with the second static friction force.

[0070] In some embodiments, the first clamping portion 118, the second clamping portion 122, and the third clamping portion 124 are located on the same axis. In this case, when the friction rod 126 moves the first lens mount 104 and the second lens mount 106 simultaneously, the first lens mount 104 and the second lens mount 106 can move stably along the same moving trajectory (e.g., towards the camera optical axis L1).

[0071] In some embodiments, such as Figure 1 and Figure 3 As shown, the second actuation assembly 114 includes a traveling wave drive 130. The traveling wave drive 130 can be a piezoelectric ceramic, a piezoelectric transistor, or a piezoelectric film (e.g., polyvinylidene fluoride). The traveling wave drive 130 is fixed to the second lens mount 106 and has a friction member 132 that contacts the friction rod 126. The traveling wave drive 130 actuates the friction member 132 to drive the friction member 132 to generate a driving force on the friction rod 126 in a direction corresponding to a traveling wave. For example, by providing a control signal (described later) to the traveling wave drive 130, the traveling wave drive 130 can control the friction member 132 to swing in the traveling wave direction according to the traveling wave of the control signal. The traveling wave direction is the same as the extension direction of the camera optical axis L1. Here, the friction member 132 drives the second lens mount 106 to move in this traveling wave direction, and the second lens mount 106 can move along the camera optical axis L1 for precise focusing movement. It should be noted that in zoom mode, the traveling wave drive 130 does not actuate the friction member 132, and the driving force generated by the friction member 132 on the friction rod 126 (the driving force can be 0 at this time) is less than the second static friction force, so that the first lens mount 104 and the second lens mount 106 can move at the same distance.

[0072] In some embodiments, such as Figure 1 and Figure 5As shown, the first clamping portion 118 has two first clamping arms 134 (e.g., U-shaped clamping arms). One end of the two first clamping arms 134 is connected to each other, and the other end of the two first clamping arms 134 is brought closer to each other by elastic force to clamp the friction rod 126 and generate a first static friction force. In some embodiments, the second clamping portion 122 has two second clamping arms 136 (e.g., U-shaped clamping arms), and the third clamping portion 124 has two third clamping arms 138 (e.g., U-shaped clamping arms). One end of the two second clamping arms 136 is connected to each other, and the other end is brought closer to each other by elastic force to clamp the friction rod 126 and generate a static friction force. One end of the two third clamping arms 138 is connected to each other, and the other end is brought closer to each other by elastic force to clamp the friction rod 126 and generate a static friction force. Here, the second static friction force may refer to the static friction force generated by the two second clamping arms 136 and the two third clamping arms 138 on the friction rod 126. In some embodiments, the first clamping arms 134 can determine the clamping force on the friction rod 126 based on the corresponding first static friction force. The second clamping arms 136 and the third clamping arms 138 can determine the clamping force on the friction rod 126 based on the second static friction force.

[0073] In some embodiments, such as Figure 5 As shown, each of the two first clamping arms 134 has a first clamping surface 135 between its two ends. The two first clamping surfaces 135 directly contact the friction rod 126 to generate a first static friction force on the friction rod 126. Each of the two second clamping arms 136 has a second clamping surface 137 between its two ends. The two second clamping surfaces 137 directly contact the friction rod 126 to generate a second static friction force on the friction rod 126. Each of the two third clamping arms 138 has a third clamping surface 139 between its two ends to generate a second static friction force on the friction rod 126. In some embodiments, the two first clamping surfaces 135, the two second clamping surfaces 137, and / or the third clamping surface 139 can be arc-shaped surfaces. This arc-shaped surface directly contacts the friction rod 126 to increase the contact area and achieve a preset static friction force.

[0074] In some embodiments, such as Figure 1As shown, the camera lens driving device 100 further includes a controller 140. The controller 140 is electrically connected to a first actuation component 112 and a second actuation component 114 to generate a first control signal and a second control signal. The first actuation component 112 generates a first movement according to the first control signal to move the first lens mount 104 and the second lens mount 106. The second actuation component 114 generates a second movement according to the second control signal with a traveling wave to move the second lens mount 106. The first movement may refer to the movement of the piezoelectric component 128 expanding, contracting, or oscillating, causing the friction rod 126 to move back to its original position. The second movement may refer to the movement of the traveling wave drive component 130 actuating the friction component 132 to oscillate or push the friction rod 126. The controller 140 may be a central processing unit (CPU), a microcontroller unit (MCU), a graphics processing unit (GPU), or a circuit board with the aforementioned chips. In some embodiments, the controller 140 may selectively send a first control signal or a second control signal depending on the zoom mode or focus mode. For example, when zooming, the controller 140 sends a first control signal to the first actuation component 112. When focusing, the controller 140 sends a second control signal to the second actuation component 114.

[0075] In some embodiments, such as Figure 6 As shown, the two guide rails (110a, 110b) can each be a ball bearing assembly 142. The first lens mount 104 and the second lens mount 106 slide on the two ball bearing assemblies 142 disposed on both sides of the frame 102. In some embodiments, the two ball bearing assemblies 142 each have a plurality of balls 144 and a receiving groove 146, with each ball 144 arranged along the receiving groove 146, movably connected, and partially exposed in the receiving groove 146. When the first lens mount 104 or the second lens mount 106 slides, each ball 144 can reduce the friction between the frame 102 and the first lens mount 104 or the second lens mount 106.

[0076] In some embodiments, such as Figure 7 and Figure 8 As shown, the first mirror mount 104 has a first sliding groove 148 and a second sliding groove 150 on each of its two sides. The first sliding groove 148 slides on the guide rail 110a, and the second sliding groove 150 slides on the guide rail 110b. It should be noted that the structures of the first mirror mount 104 and the second mirror mount 106 are similar; the structure of the second mirror mount 106 can be referred to in the structural description of the first mirror mount 104. In some embodiments, such as... Figure 2 and Figure 7As shown, the two sides of the first mirror mount 104 are magnetically attracted to the two guide rails (110a, 110b) to slide on them. The two sides of the second mirror mount 106 are magnetically attracted to the two guide rails (110a, 110b) to slide on them. Thus, the first mirror mount 104 and the second mirror mount 106 can be magnetically attracted to the two guide rails (110a, 110b) to ensure the stability of their movement.

[0077] In some embodiments, such as Figure 7 and Figure 8 As shown, the first mirror mount 104 has a magnetic attraction portion (152a, 152b) on each side. A first sliding groove 148 is located between the magnetic attraction portion 152a and the guide rail 110a, and a second sliding groove 150 is located between the magnetic attraction portion 152b and the guide rail 110b. The two magnetic attraction portions (152a, 152b) are attracted to the two guide rails (110a, 110b) by magnetic force, causing the first sliding groove 148 and the second sliding groove 150 to move closer to the two guide rails (110a, 110b) and slide on them. In some embodiments, such as Figure 8 As shown, each of the two magnetic suction parts (152a, 152b) is provided with a magnetic element 154, and the two guide rails (110a, 110b) are ferromagnetic components, allowing the magnetic suction parts (152a, 152b) to move closer to the two guide rails (110a, 110b). In some embodiments, the first mirror mount 104 is a ferromagnetic component, and the magnetic element 154 is fixed to the frame 102 and used to attract the first mirror mount 104 toward the frame 102. This allows the first slide groove 148 and the second slide groove 150 to move closer to the two guide rails (110a, 110b).

[0078] In some embodiments, such as Figure 7 As shown, the first groove 148 is one of a U-shaped groove and a V-shaped groove, and the second groove 150 is the other of a U-shaped groove and a V-shaped groove. Taking the first groove 148 as a V-shaped groove and the second groove 150 as a U-shaped groove as an example, in response to the fact that the contact area between the V-shaped first groove 148 and the guide rail 110a is greater than the contact area between the U-shaped second groove 150 and the guide rail 110b, the first groove 148 can maintain the stability of the movement of the first mirror mount 104 (or the second mirror mount 106) when it moves. The second groove 150 can reduce the friction between itself and the guide rail 110b to ensure the smooth movement of the first mirror mount 104. Thus, by designing the first groove 148 and the second groove 150 as either a V-shaped groove or a U-shaped groove, the first mirror mount 104 (or the second mirror mount 106) can achieve both stability and smooth movement.

[0079] In some embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the first actuation component 112 further includes an elastic element 156. The elastic element 156 is connected to the piezoelectric component 128. The elastic element 156 undergoes a corresponding deformation in response to actuation of the piezoelectric component 128. In some embodiments, such as Figure 9 and Figure 10 As shown, the elastic element 156 is located between the piezoelectric assembly 128 and the friction rod 126. When the piezoelectric assembly 128 is actuated (by a phase difference of the input default voltage), the piezoelectric assembly 128 elongates or shortens to varying degrees, causing the elastic element 156 to deform accordingly. This, in turn, causes the friction rod 126 to vibrate, thereby driving the first mirror mount 104 to move axially along the corresponding direction of the imaging optical axis L1. In some embodiments, such as Figure 11 As shown, the piezoelectric component 128 can also be located between the elastic element 156 and the friction rod 126. The elastic element 156 can be, for example, rubber or a spring.

[0080] In some embodiments, the number of elastic elements 156 can be one or more. Figure 10 For example, the elastic element 156 includes a first elastic element 156a and a second elastic element 156b. The first elastic element 156a and the second elastic element 156b are sandwiched within the piezoelectric assembly 128. In some embodiments, the cross-section of the piezoelectric assembly 128 has the same shape or area as the cross-section of the elastic element 156. For example... Figure 9 As shown, the piezoelectric component 128 and the elastic element 156 are formed in a stacked structural shape. For example... Figure 10 As shown, the piezoelectric component 128 and the elastic element 156 are formed into an elongated cymbal shape. For example... Figure 11 As shown, the piezoelectric component 128 and the elastic element 156 are formed into the shape of a cymbal.

[0081] In summary, in zoom mode, the camera lens driving device 100 moves the first lens mount 104 and the second lens mount 106 by means of the frictional force between the first actuation component 112 and the second lens mount 106. In focus mode, the second actuation component 114 drives the second lens mount 106 relative to the first lens mount 104 by means of the driving force generated by the second actuation component 114 on the first actuation component 112. When this driving force is greater than the maximum static frictional force between the first actuation component 112 and the second lens mount 106, the second lens mount 106 moves. Thus, the camera lens driving device 100 can perform precise zoom or focus movements. In some embodiments, the first actuation component 112 includes a piezoelectric component 128, which can move the first lens mount 104 and / or the second lens mount 106 by means of the deformation of the piezoelectric component 128, thereby increasing the moving distance of the first lens mount 104 or the second lens mount 106.
