[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] In the field of photography and videography, the anti-shake performance of the lens is crucial to ensure the stability of the captured image. Therefore, in order to improve the anti-shake performance of the lens, anti-shake parts are often installed in the lens. In order to evaluate the ability of the lens to resist slight external vibration interference in actual applications, vibration testing is usually required. By simulating the working conditions of the lens under vibration and observing the image quality of the lens in this state, the actual effect and performance of the built-in anti-shake parts of the lens can be tested.

[0042] Most existing vibration devices are single-degree-of-freedom vibrations and are unable to achieve high-frequency vibrations at small angles.

[0043] In order to solve the technical problem, the present invention provides a vibration device 100. Figure 1 and Figure 2 The vibration device 100 includes a base 1, a supporting platform 2, a connecting member 3 and a plurality of 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-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 plurality of 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 up-down direction, 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 can rotate around the upper end of the connecting member 3 at any angle under the drive of the voice coil motor 4. In addition, the displacement and time relationship curve of each voice coil motor 4 corresponding to this vibration posture can be calculated according to the required vibration axis and the required vibration frequency, and the voice coil motor 4 can be controlled to move according to the displacement and time relationship curve, so that the support platform 2 can vibrate according to the required vibration axis and the required vibration frequency. Therefore, the vibration device 100 provided by the present invention adopts the voice coil motor 4 in parallel drive, reduces the weight of the vibration part, increases the vibration frequency, is simple to operate, can adjust the angle steplessly, and can achieve the effect of 40hz high-frequency vibration under 0.2° angle vibration.

[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 make 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 movement 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 support platform 2 is connected to the output end 41 of the voice coil motor 4 upward. Since the center of the support platform 2 is connected to the upper end of the connecting member 3, the support 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 support platform 2 is connected to the output end 41 of the voice coil motor 4 downward. Similarly, the support platform 2 will tilt toward the other side without changing the center position, and the reciprocating motion is repeated in this way to realize the vibration of the vibration device 100.

[0047] It should be noted that the operating frequency of the voice coil motor 4 can usually 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 present application adopts a voice coil motor assembly, which can achieve high-frequency vibration at a small angle. The support platform 2 can vibrate around three axes within an angle range of 5°, and below the angular vibration range of 0.2°, the frequency can be as high as 40 Hz.

[0048] The present application does not limit the specific type of the voice coil motor 4. In some embodiments, please refer to Figure 3 The voice coil motor 4 includes a stator seat 43, a stator column 44, a mover column 45, a side plate 46 and a mover 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 mover column 45 is slidably arranged in the active cavity along the axial direction of the stator column 44 from the upper opening of the active cavity. The side plate 46 is arranged above the stator seat 43 and The side plate 46 is arranged at a lateral interval with the stator column 44, and a slide rail 461 is provided on the side plate 46 along the axial direction of the motor stator column 44; one end of the movable plate 47 arranged oppositely in the up-down direction is fixedly connected to the other end of the movable column 45, and the other end of the movable plate 47 arranged oppositely in the up-down direction forms the output end 41 of the voice coil motor 4, and the side of the movable plate 47 is provided with a sliding connection part 471 relative to the slide rail 461, and the sliding connection part 471 has a movement stroke along the slide rail 461. In the above-mentioned voice coil motor 4, the movable column 45 can cyclically reciprocate along the axial direction of the stator column 44 in the active cavity. It should be noted that the present application 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 a linear motion close to or away from the mounting end 42.

[0049] Furthermore, in some embodiments of the present invention, the voice coil motor assembly is provided in three parts, 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. In this way, the three voice coil motors 4 drive the support platform 2 in parallel, and the support platform 2 can rotate arbitrarily around the center of the ball head on the column. According to the required vibration axis and the required vibration frequency, the displacement and time relationship curves corresponding to the three voice coil motors 4 in this vibration posture can be calculated, and the three voice coil motors 4 can be controlled to move according to their respective displacement and time relationship curves, so that the support platform 2 can vibrate according to the required vibration axis and the required vibration frequency, which can not only realize three-degree-of-freedom high-frequency vibration at a small angle, but also realize stepless adjustment and adjust any vibration angle within the motor travel range.

[0050] It should be noted that the three positions where the three voice coil motors 4 are connected to the lower end surface of the support platform 2 can be designed by oneself. Preferably, the above three positions can be positions on a circumference with the position where the connecting member 3 is connected to the support platform 2 as the center. More preferably, the above three positions divide the above circumference equally.

[0051] In some other embodiments, the voice coil motor assembly may also be configured to be four, five, six, etc., to achieve vibrations with other degrees of freedom.

[0052] Furthermore, the vibration device 100 also includes a control component, which is electrically connected to the plurality of voice coil motors 4 to control the movement of the voice coil motors 4. The control component can control different voice coil motors 4 to move according to different displacement and time relationship curves, so that the support platform 2 has the required vibration movement. In one embodiment, the control component can be set as a controller, which receives input signals from sensors or other devices, and generates corresponding output signals according to a preset control strategy or algorithm, thereby achieving precise control of the controlled object. In other embodiments, the control component can also be assembled by a flexible circuit board, a chip structure, and a power device. By inputting the required vibration angle and frequency into the control component, the control component can automatically solve the displacement and time curves of each voice coil motor 4, and control each voice coil motor 4 to move according to their respective displacement and time curve relationships, so that the support platform 2 achieves the required vibration angle and frequency.

[0053] Furthermore, each of the voice coil motor components further includes a first transmission component 5 and a second transmission component 6, wherein the first transmission component 5 is transmission-connected to the output end 41 of the voice coil motor 4 and the lower end surface of the carrier 2, and the second transmission component 6 is transmission-connected to the mounting end 42 of the voice coil motor 4 and the base 1. Through the first transmission component 5, when the output end 41 of one of the voice coil motors 4 moves, the connection between the lower end surface of the carrier 2 and the voice coil motor 4 can be driven to move accordingly; through the second transmission component 6, the mounting end 42 of each voice coil motor 4 is transmission-connected to the fixed position of the base 1, and when the output end 41 of one of the voice coil motors 4 moves, its mounting end 42 can rotate relative to the above-mentioned fixed position.

[0054] For further information, please refer to Figure 4 and Figure 7 In 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 arranged opposite to each other in the vertical direction. Each mounting seat 51 includes a seat body 511 and two connecting arms 512. The seat body 511 has a first side surface and a second side surface arranged opposite to each other in the vertical direction. The two opposite ends of the first side surface are connected to the two connecting arms 512, 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 parts of the two columns are fixed, and the extension directions intersect, and the two ends of each column are respectively rotatably connected to the two connecting arms 512 of each mounting seat 51, so that the two mounting seats 51 can be rotated along the axis of the two columns. In this way, the output end 41 of the voice coil motor 4 can have two degrees of freedom of relative rotation, so that complex motion trajectories and posture adjustments can be performed in a given space, and stable and flexible support and rotation functions are provided.

[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 application does not impose any limitation thereto, as long as the functions that can be achieved by the above-mentioned 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 a connecting seat 53.

[0057] Therefore, in some embodiments, a mounting groove 513 is provided on the second side of the seat body 511, and a first pin hole 514 is transversely penetrated through the seat body 511. The first transmission assembly 5 also includes two connecting seats 53, each of which 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, and a mounting hole can be provided on the periphery of the mounting plate 531 for installation 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 through 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 communicated with the second pin hole 533, and when the first pin hole 514 is communicated with the second pin hole 533, the latch is penetrated through the first pin hole 514 and the second pin hole 533. During installation, the installation column 532 is inserted into the installation groove 513, and the first pin hole 514 is connected to the second pin hole 533, and then the latch is inserted to fix the installation column 532 to the installation groove 513. In the above manner, the first transmission assembly 5 can be detachably connected to the output end 41 of the voice coil motor 4 or to the lower end surface of the supporting platform 2, and the connection is convenient and easy to operate.

[0058] For further information, please refer to Figure 5 , the base 1 is provided with a first matching seat 61, and the first matching seat 61 is provided with a first groove 611; the mounting end 42 of the voice coil motor 4 is matched with the first groove 611 of the first matching seat 61 through a ball joint to form the second transmission assembly 6. Such a configuration can effectively prevent the mounting end 42 of the voice coil motor 4 from moving vertically and left and right relative to the base 1, ensure the overall stability of the structure, and enable the mounting end 42 of the voice coil motor 4 to rotate around the mounting position on the base 1. In addition, the ball joint can withstand a large vertical load, so it is arranged between the voice coil motor 4 and the base 1 to better bear the weight of the voice coil motor 4.

[0059] It should be noted that the specific settings of the first transmission assembly 5 and the second transmission assembly 6 can be set simultaneously or separately. When the two are set simultaneously, the bottom mounting end 42 of the voice coil motor 4 is arranged on the base 1 through a ball joint, and the ball joint can provide support for the voice coil motor 4 and realize the movable connection of the voice coil motor 4 on 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 through the above-mentioned Hooke's joint. During the movement of the voice coil motor 4, multi-degree-of-freedom vibration can be better realized.

[0060] Furthermore, a magnetic grid sensor is provided on the voice coil motor 4. The magnetic grid sensor has the advantages of high precision, high speed, high sensitivity and strong anti-interference ability, and can work stably in a complex environment to achieve accurate measurement of small displacement changes. By providing a magnetic grid sensor in the voice coil motor 4, high-precision position feedback of the support platform 2 can be achieved.

[0061] For further information, please refer to Figure 6 The upper end of the connecting member 3 is provided with a second matching seat 71, and the second matching seat 71 is provided with a second groove 711; the lower end surface of the bearing platform 2 is matched with the second groove 711 of the second matching seat 71 through a ball joint. The second matching seat 71 is fixedly arranged at the upper end of the connecting member 3, and the center position of the lower end surface of the bearing platform 2 is matched with the second matching seat 71 through a ball joint, so that the bearing platform 2 can be better supported while being able to rotate in any direction around the center position of the lower end surface of the bearing platform 2.

[0062] The present invention also proposes a lens vibration test device, which includes the vibration device 100 as described above. The lens can be mounted on the support platform 2 of the vibration device 100. Of course, it can be understood that a fixing device can be installed on the upper end surface of the support platform 2 so that the lens can be easily installed and removed on the upper end surface of the support platform 2. Then, according to the vibration angle and frequency required for the lens test, each voice coil motor 4 is controlled to move according to the relationship between their displacement and time curves, 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 refers to the above embodiment. Since the lens vibration test device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0063] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
