[0041] In the fields of photography and videography, lens stabilization is crucial for ensuring image stability. Therefore, to enhance this performance, lenses are often built with stabilization components. To assess a lens's ability to withstand even minor external vibrations in real-world applications, vibration testing is typically performed. This simulates the lens's operating conditions under vibration and observes the image quality captured in this state to verify the effectiveness and performance of the lens' built-in stabilization components.
[0042] Most existing vibration devices are single-degree-of-freedom vibrations and cannot achieve high-frequency vibrations at small angles.
[0043] In order to solve this technical problem, the present invention provides a vibration device 100, please refer to Figure 1 and Figure 2 The vibration device 100 includes a base 1, a supporting platform 2, a connecting member 3 and multiple voice coil motor assemblies. The supporting platform 2 is rotatably mounted to the upper end of the base 1, and the upper end surface of the supporting platform 2 is used to place a lens; the connecting member 3 is extended in the up and down direction, the lower end of the connecting member 3 is fixedly connected to the base 1, and the upper end of the connecting member 3 is rotatably connected to the center position of the lower end surface of the supporting platform 2; the multiple voice coil motor assemblies are arranged around the connecting member 3, each of the voice coil motor assemblies includes a voice coil motor 4, the voice coil motor 4 has an output end 41 and a mounting end 42 arranged opposite to each other in the upper and lower directions, the output end 41 of the voice coil motor 4 is rotatably connected to the lower end surface of the supporting platform 2, and the mounting end 42 of the voice coil motor 4 is rotatably connected to the base 1.
[0044] In the technical solution provided by the present invention, the support platform 2, driven by the voice coil motor 4, can rotate around the upper end of the connecting member 3 at any angle. Furthermore, based on the desired vibration axis and frequency, a displacement-time relationship curve corresponding to each voice coil motor 4 in this vibration posture can be calculated. The voice coil motor 4 can then be controlled to move according to this displacement-time relationship curve, thereby causing the support platform 2 to vibrate according to the desired vibration axis and frequency. Therefore, the vibration device 100 provided by the present invention utilizes parallel drive of the voice coil motors 4, reducing the weight of the vibrating components and increasing the vibration frequency. Furthermore, the device is simple to operate and allows for infinitely adjustable angles, capable of achieving a high-frequency vibration of 40 Hz at a 0.2° angle.
[0045] It should be noted that the center position of the lower end surface of the supporting platform 2 is the support point position that can keep the supporting platform 2 in a balanced state, that is, when the supporting platform 2 is set in a plate shape, the center position of the lower end surface of the supporting platform 2 is the center of gravity of the lower end surface.
[0046] It can be understood that, in the voice coil motor 4, the output end 41 has a linear motion close to the mounting end 42 or away from the mounting end 42. When the output end 41 moves in a direction away from the mounting end 42, the output end 41 can push the position where the supporting platform 2 is connected to the output end 41 of the voice coil motor 4 upward. Since the center of the supporting platform 2 is connected to the upper end of the connecting member 3, the supporting platform 2 will tilt toward one side without changing the center position; when the output end 41 moves in a direction close to the mounting end 42, the output end 41 can pull the position where the supporting platform 2 is connected to the output end 41 of the voice coil motor 4 downward. Similarly, the supporting platform 2 will tilt toward the other side without changing the center position. This reciprocating motion is repeated to achieve vibration of the vibration device 100.
[0047] It should be noted that the operating frequency of the voice coil motor 4 can typically reach thousands to tens of thousands of hertz. This high-frequency characteristic enables the voice coil motor 4 to complete a large number of fast and precise motion control tasks in a very short time. Therefore, the voice coil motor assembly used in the present invention can achieve high-frequency vibration at small angles. The support platform 2 can vibrate within an angular range of 5° around three axes, and within an angular range of less than 0.2°, the frequency can reach up to 40 Hz.
[0048] The present invention does not limit the specific type of the voice coil motor 4. In some embodiments, please refer to Figure 3The voice coil motor 4 includes a stator seat 43, a stator column 44, a movable column 45, a side plate 46 and a movable plate 47. The lower end of the stator seat 43 forms the mounting end 42 of the voice coil motor 4. The stator column 44 is arranged above the stator seat 43 in the vertical direction. The stator column 44 is provided with an active cavity, and the active cavity has an upper opening; one end of the movable column 45 slides from the upper opening of the active cavity along the axial direction of the stator column 44 and is arranged in the active cavity; the side plate 46 is arranged above the stator seat 43 and The side plate 46 is laterally spaced from the stator column 44, and a slide rail 461 is provided on the side plate 46 along the axis of the motor stator column 44. One end of the movable plate 47, which is disposed oppositely in the vertical direction, is fixedly connected to the other end of the movable plate 45. The other end of the movable plate 47, which is disposed oppositely in the vertical direction, forms the output end 41 of the voice coil motor 4. A sliding connection portion 471 is provided on the side of the movable plate 47 relative to the slide rail 461, and the sliding connection portion 471 has a motion stroke along the slide rail 461. In the above-mentioned voice coil motor 4, the movable column 45 is capable of cyclic reciprocating motion within the active cavity along the axis of the stator column 44. It should be noted that the present invention is not limited to the above-mentioned voice coil motor 4, and voice coil motors 4 of other structures can also be used, as long as the output end 41 of the voice coil motor 4 can achieve linear motion toward or away from the mounting end 42.
[0049] Furthermore, in some embodiments of the present invention, three voice coil motor assemblies are provided, and the output ends 41 of the three voice coil motors 4 are rotatably connected to the lower end surface of the support platform 2 and are distributed along the circumference. This arrangement allows the three voice coil motors 4 to drive the support platform 2 in parallel, allowing the support platform 2 to rotate arbitrarily around the center of the ball head on the pillar. Based on the desired vibration axis and frequency, the displacement-time relationship curves corresponding to the three voice coil motors 4 in this vibration posture can be calculated. The three voice coil motors 4 are then controlled to move according to their respective displacement-time relationship curves, causing the support platform 2 to vibrate according to the desired vibration axis and frequency. This not only achieves three-degree-of-freedom high-frequency vibration at a small angle, but also enables infinite adjustment and adjustment of any vibration angle within the motor's travel range.
[0050] It should be noted that the three positions at which the three voice coil motors 4 are connected to the lower end surface of the supporting platform 2 can be designed by oneself. Preferably, the above three positions can be positions on the circumference of a circle with the position where the connecting member 3 is connected to the supporting platform 2 as the center of the circle. More preferably, the above three positions divide the above circumference equally.
[0051] In some other embodiments, the voice coil motor assembly can also be arranged to be four, five, six, etc., to achieve vibrations with other degrees of freedom.
[0052] Furthermore, the vibration device 100 includes a control component electrically connected to the plurality of voice coil motors 4 to control the movement of the voice coil motors 4. The control component is capable of controlling the movement of different voice coil motors 4 according to different displacement-time curves, thereby causing the support platform 2 to exhibit the desired vibration motion. In one embodiment, the control component can be configured as a controller that receives input signals from sensors or other devices and generates corresponding output signals based on a preset control strategy or algorithm, thereby achieving precise control of the controlled object. In other embodiments, the control component can also be independently adapted and assembled from a flexible printed circuit board, a chip structure, and a power device. By inputting the desired vibration angle and frequency into the control component, the control component can automatically determine the displacement-time curve of each voice coil motor 4 and control the movement of each voice coil motor 4 according to its respective displacement-time curve, thereby causing the support platform 2 to achieve the desired vibration angle and frequency.
[0053] Furthermore, each voice coil motor assembly includes a first transmission assembly 5 and a second transmission assembly 6. The first transmission assembly 5 provides a transmission connection between the output end 41 of the voice coil motor 4 and the lower end surface of the support platform 2, while the second transmission assembly 6 provides a transmission connection between the mounting end 42 of the voice coil motor 4 and the base 1. The first transmission assembly 5 enables movement of the output end 41 of a voice coil motor 4 to drive the connection between the lower end surface of the support platform 2 and the voice coil motor 4 to move accordingly. The second transmission assembly 6 ensures that the mounting end 42 of each voice coil motor 4 is connected to a fixed position on the base 1. Movement of the output end 41 of a voice coil motor 4 allows the mounting end 42 to rotate relative to the fixed position.
[0054] Further, please refer to Figure 4 and Figure 7In some embodiments, the first transmission assembly 5 includes a Hooke's hinge, which includes two mounting seats 51 and a transmission member 52. The two mounting seats 51 are vertically opposed, each mounting seat 51 including a base 511 and two connecting arms 512. The base 511 has a first side surface and a second side surface disposed vertically opposite each other. The first side surface is connected to the two connecting arms 512 at opposite ends, and the second side surface is fixedly connected to the mover of the voice coil motor 4 or the lower end surface of the support platform 2. The transmission member 52 includes two columns, the middle portions of which are fixed and extend in intersecting directions. The ends of each column are rotatably connected to the two connecting arms 512 of each mounting seat 51, allowing the two mounting seats 51 to rotate along the axes of the two columns. This configuration enables the output end 41 of the voice coil motor 4 to have two degrees of relative rotational freedom, thereby enabling complex motion trajectories and posture adjustments within a given space, and providing stable and flexible support and rotation functions.
[0055] It should be noted that the first transmission assembly 5 can also be configured as a Hooke's hinge or other connecting member 3 in other structural forms, and the present invention does not impose any restrictions thereon, as long as the functions achievable by the above structure can be achieved.
[0056] When the second side surface of the mounting seat 51 is fixedly connected to the output end 41 of the voice coil motor 4 or the lower end surface of the supporting platform 2, it can be directly connected in an undetachable manner, or it can be detachably fixedly connected by screws and nuts or other means, or it can be connected through the connecting seat 53.
[0057] Therefore, in some embodiments, a mounting groove 513 is provided on the second side surface of the base body 511, and a first pin hole 514 is transversely penetrated by the base body 511. The first transmission assembly 5 also includes two connecting seats 53, each of the connecting seats 53 includes a mounting plate 531, a mounting column 532 and a latch. The mounting plate 531 is used to be fixedly connected to the output end 41 of the voice coil motor 4 or the lower end surface of the supporting platform 2. A mounting hole can be provided on the periphery of the mounting plate 531 for mounting to the corresponding voice coil motor 4 or the supporting platform 2; the mounting column 532 is provided on the mounting plate 531, and a second pin hole 533 is penetrated by the mounting column 532. The outer wall of the mounting column 532 is adapted to the mounting groove 513, so that when the mounting column 532 extends into the mounting groove 513, the first pin hole 514 is connected with the second pin hole 533. When the first pin hole 514 is connected with the second pin hole 533, the latch is passed through the first pin hole 514 and the second pin hole 533. During installation, the mounting post 532 is inserted into the mounting slot 513, connecting the first pin hole 514 with the second pin hole 533, and then the latch is inserted to secure the mounting post 532 to the mounting slot 513. This method enables a detachable connection between the first transmission assembly 5 and the output end 41 of the voice coil motor 4 or the lower end surface of the supporting platform 2, and the connection is convenient and easy to operate.
[0058] Further, please refer to Figure 5 The base 1 is provided with a first mating seat 61 having a first groove 611 therein. The mounting end 42 of the voice coil motor 4 engages with the first groove 611 of the first mating seat 61 via a ball joint to form the second transmission assembly 6. This arrangement effectively prevents the mounting end 42 of the voice coil motor 4 from vertically and horizontally moving relative to the base 1, ensuring overall structural stability while allowing the mounting end 42 of the voice coil motor 4 to rotate about its mounting position on the base 1. Furthermore, the ball joint can withstand significant vertical loads, so its placement between the voice coil motor 4 and the base 1 better supports the weight of the voice coil motor 4.
[0059] It should be noted that the specific configuration of the first transmission assembly 5 and the second transmission assembly 6 can be provided simultaneously or separately. When both are provided simultaneously, the bottom mounting end 42 of the voice coil motor 4 is mounted on the base 1 via a ball hinge. The ball hinge provides support for the voice coil motor 4 and enables the movable connection of the voice coil motor 4 to the base 1. The top output end 41 of the voice coil motor 4 is connected to a specific position of the support platform 2 via the aforementioned Hooke's hinge. During the movement of the voice coil motor 4, multi-degree-of-freedom vibration can be better achieved.
[0060] Furthermore, the voice coil motor 4 is equipped with a magnetic grating sensor. This sensor offers advantages such as high precision, high speed, high sensitivity, and strong anti-interference capabilities. It can operate stably in complex environments and accurately measure even tiny displacement changes. By installing a magnetic grating sensor in the voice coil motor 4, high-precision position feedback of the support platform 2 can be achieved.
[0061] Further, please refer to Figure 6 The upper end of the connecting member 3 is provided with a second mating seat 71, which is provided with a second groove 711. The lower end surface of the supporting platform 2 engages with the second groove 711 of the second mating seat 71 via a ball joint. The second mating seat 71 is fixed to the upper end of the connecting member 3, and the center of the lower end surface of the supporting platform 2 engages with the second mating seat 71 via a ball joint, so that the supporting platform 2 can be better supported while being able to rotate in any direction around the center of the lower end surface of the supporting platform 2.
[0062] The present invention also provides a lens vibration test device, which includes the vibration device 100 described above. A lens can be mounted on the support platform 2 of the vibration device 100. It is understood that a fixing device can be installed on the upper end surface of the support platform 2 to facilitate installation and removal of the lens from the upper end surface of the support platform 2. Subsequently, based on the vibration angle and frequency required for lens testing, each voice coil motor 4 is controlled to move according to its respective displacement-time curve relationship, so that the support platform 2 drives the lens to achieve the required vibration angle and frequency, and then the required test is performed. The specific structure of the vibration device 100 in the lens vibration test device is similar to the above-mentioned embodiment. Since the lens vibration test device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.
[0063] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
