Description

Technical Field

[0001] This application relates to the field of vibration reduction equipment technology, and in particular to a vibration reduction mechanism and a shooting device. Background Technology

[0002] With the development of science and technology, more and more objects are accompanied by movement. Typically, the object (load) is connected to a mobile platform, and the mobile platform drives the load to move. For example, a camera is mounted on a mobile platform such as a drone or an automated guided vehicle (AGV), and the mobile platform drives the camera to carry out aerial photography operations.

[0003] Currently, to ensure the stability of the camera, a vibration damping mechanism is configured on the mobile platform. Typically, this mechanism consists of multiple damping balls that absorb or isolate vibrations experienced by the camera, thereby improving its stability during shooting. Generally, these damping balls have different projective stiffnesses in the XYZ three-dimensional space, and the energy decoupling rate is improved by adjusting the span between the balls and their positional relationship with the load's center of mass, resulting in lower energy coupling of different mode shapes. However, the relatively large distance between the centroids of these multiple damping balls requires significant installation space and places high demands on their placement, leading to a large overall structure for the vibration damping mechanism and hindering its layout and installation. Summary of the Invention

[0004] Therefore, it is necessary to provide a vibration damping mechanism and shooting equipment to address the problem that the existing vibration damping mechanism has a large overall structure and requires a large installation space.

[0005] A vibration damping mechanism, the vibration damping mechanism comprising:

[0006] Multiple vibration damping units are spaced apart on a load-bearing mechanism, and when a load is connected to the load, the load is in contact with all of the vibration damping units. Each vibration damping unit is at least partially a flexible component.

[0007] At least two of the vibration damping units are made of at least some different materials;

[0008] And / or, at least two of the vibration damping units have at least partially different outer contours;

[0009] And / or, at least two of the vibration damping units are in at least partially different temperature environments.

[0010] In one embodiment, the vibration damping unit includes vibration damping balls, and a plurality of the vibration damping balls are arranged to form an installation space for mounting the load.

[0011] In one embodiment, the vibration damping unit further includes heating elements, and a plurality of heating elements are correspondingly embedded in a plurality of vibration damping balls.

[0012] In one embodiment, the vibration damping mechanism further includes a heat source module for controlling the regional temperature of each of the vibration damping balls.

[0014] In one embodiment, the outer contour of the damping sphere is at least one of spherical, cylindrical, and prismatic shapes.

[0015] In one embodiment, the vibration damping mechanism further includes a bracket detachably connected to at least one of the vibration damping units, and the load can be connected to the bracket.

[0016] In one embodiment, the support includes a load-bearing portion and a connecting portion, the load-bearing portion being able to connect to the load, and the connecting portion being detachably connected to the vibration damping unit.

[0017] In one embodiment, there are two supports, and the two supports are symmetrically arranged on opposite sides of the load-bearing mechanism, and the opposite ends of the load can be connected to the two supports respectively.

[0018] A shooting device, the shooting device comprising:

[0019] The support mechanism has an installation space;

[0020] The vibration damping mechanism as described in any of the above technical solutions includes multiple vibration damping units, all of which are disposed on the bearing mechanism and spaced apart in the installation space; and

[0021] The camera is detachably mounted on the support mechanism and located in the installation space. When the camera is connected to the support mechanism, the outer contour of the camera is in contact with the plurality of vibration damping units.

[0022] In the aforementioned vibration damping mechanism and imaging equipment, at least a portion of the vibration damping unit is a flexible component. The vibration damping unit can isolate vibration transmission to the load, and when the load vibrates, the vibration damping unit deforms to absorb the vibration generated by the load, thereby reducing the vibration of the load. At least two vibration damping units are made of different materials, and / or at least two vibration damping units are located in different temperature environments. When the load vibrates and transmits the vibration to the vibration damping unit, at least two vibration damping units undergo desired deformation in different directions, thereby adjusting the resonant frequency of the vibration damping mechanism and reducing the energy coupling effect generated by the load during vibration, thus reducing the vibration of the load. Furthermore, when at least two vibration damping units have different outer contours, at least two vibration damping units have different stiffness characteristics, which can also adjust the resonant frequency of the vibration damping mechanism and reduce the energy coupling effect generated by the load during vibration, thereby reducing the vibration of the load. The vibration damping mechanism provided in this application adjusts the resonant frequency of the vibration damping mechanism by setting different materials, outer contours and / or temperature environments for some or all of the vibration damping units. At the same time, it reduces the energy coupling effect generated by the load during vibration, thereby improving the stability of the load. Furthermore, multiple vibration damping units can be arranged around the load, reducing the overall volume of the vibration damping mechanism and facilitating its layout and installation.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0039] See Figure 1 and Figure 2 As shown, when the load 300 is connected to the bearing mechanism 200, a vibration damping mechanism 100 is provided at the connection between the load 300 and the bearing mechanism 200. Since the mass of the bearing mechanism 200 is usually larger than that of the load 300, for ease of discussion, the vibration damping mechanism 100 is simplified to a multi-degree-of-freedom load 300 vibrating under the support of multiple vibration damping units 110. Neglecting the damping effect, the free vibration differential equation of the module composed of the vibration damping mechanism 100, the bearing mechanism 200, and the load 300 is:

[0040]

[0041] Taking a 6-DOF load as an example, the matrix M of a load of 300 can be represented as:

[0042]

[0043] Matrix M is a symmetric matrix composed of a mass diagonal matrix and an inertia tensor. The inertia tensor is diagonalizable, and its three linearly independent eigenvectors correspond to three direction vectors, representing the three principal inertial axis directions of the load 300.

[0044] Matrix K is the stiffness matrix of the vibration damping mechanism 100. Matrix K can be expressed as:

[0045] Among them, K i K represents the stiffness characteristic of the i-th damping unit 110 of the damping mechanism 100. i T is the diagonal matrix of the stiffnesses along the elastic principal axes of the vibration damping unit 110. i This represents the cosine matrix of the elastic principal axis direction and the xyz direction of the vibration damping unit 110. Matrix K i With matrix T i It can be represented as:

[0046]

[0047] The design of the vibration damping mechanism 100, the load-bearing mechanism 200, and the load 300 module mainly involves adjusting the relationship between the M matrix and the K matrix, so that the eigenvalues ​​(modal angular frequencies) and eigenvectors (modal patterns) of the free vibration differential equation of the vibration damping mechanism 100, the load-bearing mechanism 200, and the load 300 module reach the expected design goals.

[0048] Generally, for a specific load 300, the M matrix of load 300 is predetermined or has little room for optimization. Therefore, the design of the vibration damping mechanism 100 mainly focuses on the design and adjustment of the K matrix. Traditionally, the vibration damping mechanism 100 includes multiple damping balls 111 of the same type, because the K of each damping unit 110... i They are exactly the same, and can only be adjusted by changing T. i To adjust the K matrix, it is necessary to adjust the spatial arrangement, angle, and other parameters of each damping unit 110. However, when the installation space for the damping mechanism 100 is small, or even completely fixed, the selectable support positions and angle adjustments for the damping units 110 are limited, i.e., T... i The degree of freedom in adjustment is relatively low.

[0049] To address the aforementioned problems, this application provides a vibration damping mechanism 100, which enables K to... i It can be adjusted because there is no need to adjust T. i Adjustments can reduce the overall volume of the vibration damping mechanism 100, which is beneficial for the layout and installation of the vibration damping mechanism 100, especially suitable for the layout and installation of the vibration damping mechanism 100 in small spaces.

[0050] Specifically, see Figure 1 and Figure 2As shown, the vibration damping mechanism 100 includes multiple vibration damping units 110. The vibration damping mechanism 100 is configured on the load-bearing mechanism 200 so that when the load 300 is connected to the load-bearing mechanism 200, the vibration damping mechanism 100 can reduce the vibration of the load 300, thereby improving the stability of the load 300. The load-bearing mechanism 200 can be an Automated Guided Vehicle (AGV), a robot, a drone, etc., and the load 300 can be various single-degree-of-freedom or multi-degree-of-freedom objects that require vibration in their working environment, such as optical instruments, gimbals and their loads, cameras, etc.

[0051] Multiple vibration damping units 110 are spaced apart on the load-bearing mechanism 200, and when the load-bearing mechanism 200 is connected to a load 300, the load 300 is in contact with all of the vibration damping units 110. At least a portion of each vibration damping unit 110 is a flexible component; that is, a portion of the vibration damping unit 110 is made of flexible material, or all of the vibration damping unit 110 is made of flexible material. Since at least a portion of each vibration damping unit 110 is flexible, its vibration transmission effect is weaker than that of rigid components. The vibration damping unit 110 can isolate external vibrations from being transmitted to the load 300, especially providing good isolation for high-frequency vibrations. When the load 300 vibrates, because the load 300 is in contact with the vibration damping unit 110, the vibration of the load 300 can be transmitted to the vibration damping unit 110, allowing the vibration damping unit 110 to deform. The vibration damping unit 110 can absorb the vibration generated by the load 300, thereby reducing the vibration of the load 300 and improving the stability of the load 300.

[0052] At least two vibration damping units 110 are made of at least a portion of different materials, and / or, at least a portion of the outer contours of at least two vibration damping units 110 are different, and / or, at least a portion of the temperature environments in which at least two vibration damping units 110 are located are different. In other words, at least two vibration damping units 110 contain one or more of the above three characteristics. Wherein, at least two vibration damping units 110 are made of at least a portion of different materials, and / or, at least a portion of the temperature environments in which at least two vibration damping units 110 are located are different, the material and / or the temperature environment of the vibration damping units 110 can be adjusted to adjust the temperature environment of K. i The internal numerical ratio is adjusted so that when the load 300 vibrates and transmits the vibration to the damping unit 110, at least two damping units 110 undergo the desired deformation in different directions, thereby adjusting the resonant frequency of the damping mechanism 100 and reducing the energy coupling effect generated by the load 300 during vibration, thus reducing the vibration of the load 300. Furthermore, when at least a portion of the outer contours of the at least two damping units 110 are different, the K-axis of the at least two damping units 110 is adjusted accordingly. iBy adjusting the values, at least two damping units 110 have different stiffness characteristics, which can also adjust the resonant frequency of the damping mechanism 100 and reduce the energy coupling effect generated by the load 300 during vibration.

[0053] The aforementioned vibration damping mechanism 100 adjusts the resonant frequency of the vibration damping mechanism 100 by setting different materials, outer contours, and / or temperature environments for some or all of the vibration damping units 110. At the same time, it reduces the energy coupling effect generated by the load 300 during vibration, thereby improving the stability of the load 300. Furthermore, multiple vibration damping units 110 can be arranged around the load 300, reducing the overall volume of the vibration damping mechanism 100 and facilitating its layout and installation.

[0054] In one embodiment, see Figure 1 and Figure 2 As shown, the vibration damping unit 110 includes damping balls 111, and multiple damping balls 111 surround an installation space 112, which can accommodate the load 300. When the load 300 is connected to the bearing mechanism 200 and the load 300 is located within the installation space 112, the outer contour of the load 300 is in contact with the multiple damping balls 111. On the one hand, the multiple damping balls 111 can constrain or limit the installation of the load 300, preventing the load 300 from shaking excessively during operation. On the other hand, the damping balls 111 can isolate external vibrations from being transmitted to the load 300. When the load 300 vibrates, the damping balls 111 undergo elastic deformation due to contact between the load 300 and the damping balls 111, which can absorb the vibration generated by the load 300, thereby reducing the vibration of the load 300.

[0055] In one embodiment, see Figure 1 and Figure 2 As shown, the vibration damping unit 110 also includes heating elements (not shown). Multiple heating elements are correspondingly embedded in multiple damping balls 111, meaning that a heating element is embedded in each damping ball 111. The temperature environment of the damping ball 111 is controlled by the heating elements. Since each heating element can independently control the temperature of its respective area within the damping ball 111, the temperature of each area within the damping ball 111 can be controlled within a preset temperature range, so that at least a portion of the temperature environment of at least two vibration damping units 110 is different. The flexible portion of the vibration damping unit 110 deforms at high temperatures, and because the temperature environments of at least two vibration damping units 110 are different, the temperature environment of the damping balls 111 can be adjusted to control the temperature of the damping ball 111. iThe internal numerical ratio is adjusted so that when the load 300 vibrates and transmits the vibration to each damping unit 110, at least two damping balls 111 will produce the desired deformation in different directions, thereby adjusting the resonant frequency of the damping mechanism 100 and reducing the energy coupling effect generated by the load 300 during vibration, thereby reducing the vibration of the load 300.

[0056] The heating element can be a resistance wire, heating rod, or other element that can generate heat. This application does not limit the specific type of heating element.

[0057] In another embodiment, see Figure 1 and Figure 2 As shown, the vibration damping mechanism 100 also includes a heat source module (not shown), which is used to control the regional temperature of each damping ball 111. By covering the outside of the multiple damping balls 111 with the heat source module, the temperature environment of each damping ball 111 can be controlled by controlling the different amounts of heat generated in each region of the heat source module. Since the heat source module can independently control the regional temperature of each damping ball 111, the regional temperature of each damping ball 111 can be controlled within a preset temperature range, so that at least two damping units 110 are at least partially in different temperature environments. When the flexible portion of the damping unit 110 deforms at high temperatures, and because the temperature environments of at least two damping units 110 are different, when the load 300 vibrates and transmits the vibration to each damping unit 110, at least two damping balls 111 undergo the desired deformation in different directions, thereby adjusting the resonant frequency of the vibration damping mechanism 100 and reducing the energy coupling effect generated by the load 300 during vibration, thus reducing the vibration of the load 300.

[0058] The heat source module can be a heating lamp, an oven, or other components that can generate heat. This application does not limit the specific type of heat source module.

[0059] For example, see [link to relevant documentation] Figure 3 As shown in this embodiment, the vibration damping mechanism 100 includes four damping balls 111, which are defined as a first damping ball 1111, a second damping ball 1112, a third damping ball 1113, and a fourth damping ball 1114. The regional temperature of the four damping balls 111 can be controlled, for example, making the temperature environments of the regions where the first damping ball 1111 and the third damping ball 1113 are located different, and making the temperature environments of the regions where the second damping ball 1112 and the fourth damping ball 1114 are located different. Of course, in other feasible embodiments, the number of damping balls 111 and the corresponding relationship of the regional ambient temperatures of each damping ball 111 can be different, and this application does not impose any limitations.

[0060] In one embodiment, see Figure 1 and Figure 2 As shown, the damping ball 111 is a flexible component, and it is made of one or more of silicone, plastic, and rubber. The damping ball 111 can be integrally molded using only a portion of silicone, plastic, or rubber through injection molding or similar methods; it can also be integrally molded using only one of silicone, plastic, or rubber through injection molding or similar methods; or it can be injection molded from a mixture of silicone, plastic, and rubber through injection molding or similar methods. This allows at least two damping balls 111 to be made of at least a portion of different materials. By adjusting the material of the damping ball 111, K can be adjusted. i The internal numerical ratio is adjusted so that when the load 300 vibrates and transmits the vibration to each damping unit 110, at least two damping balls 111 will produce the desired deformation in different directions, thereby adjusting the resonant frequency of the damping mechanism 100 and reducing the energy coupling effect generated by the load 300 during vibration, thereby reducing the vibration of the load 300.

[0061] It should be noted that the specific material of the damping ball 111 is not limited to the silicone, plastic and rubber provided above. It can also be other materials with good flexibility such as polyurethane. This application does not restrict the specific material type of the damping ball 111, as long as the molded damping ball 111 has flexibility.

[0062] For example, see [link to relevant documentation] Figure 3 As shown in this embodiment, the vibration damping mechanism 100 includes four damping balls 111, which are defined as a first damping ball 1111, a second damping ball 1112, a third damping ball 1113, and a fourth damping ball 1114. The molding materials of the four damping balls 111 can be controlled; for example, the molding materials of the first damping ball 1111 and the third damping ball 1113 can be different, and the molding materials of the second damping ball 1112 and the fourth damping ball 1114 can be different. Of course, in other feasible embodiments, the number of damping balls 111 and the correspondence of the molding materials of each damping ball 111 can be different, and this application does not impose any limitations.

[0063] In one embodiment, see Figure 1 and Figure 2 As shown, the outer contour of the damping sphere 111 is at least one of spherical, cylindrical, and prismatic shapes. Specifically, the damping sphere 111 may have a partial outer contour of one or more of spherical, cylindrical, and prismatic shapes, or it may have an overall outer contour of one or more of spherical, cylindrical, and prismatic shapes. This allows at least two damping spheres 111 to have at least partially different outer contours, thereby affecting the K-axis of at least two damping units 110. iBy adjusting the values, at least two damping units 110 have different stiffness characteristics, which can also adjust the resonant frequency of the damping mechanism 100 and reduce the energy coupling effect generated by the load 300 during vibration.

[0064] For example, see [link to relevant documentation] Figure 3 As shown in this embodiment, the vibration damping mechanism 100 includes four damping balls 111, which are defined as a first damping ball 1111, a second damping ball 1112, a third damping ball 1113, and a fourth damping ball 1114. The outer contours of the four damping balls 111 can be controlled, for example, making the outer contours of the first damping ball 1111 and the third damping ball 1113 different, and making the outer contours of the second damping ball 1112 and the fourth damping ball 1114 different. Of course, in other feasible embodiments, the number of damping balls 111 and the correspondence of their outer contours can be different, and this application does not impose any limitations.

[0065] In one embodiment, see Figures 1-3 As shown, the vibration damping mechanism 100 also includes a bracket 113, which is detachably connected to at least one vibration damping unit 110. The load 300 can be connected to the bracket 113. Thus, the load 300 is mounted on the bearing mechanism 200 via the bracket 113, enabling the bearing mechanism 200 to drive the load 300 to perform dynamic operations. Since the bracket 113 is connected to the vibration damping unit 110, when the load 300 is connected to the bracket 113, the vibration damping unit 110 is indirectly connected to the bearing mechanism 200 via the bracket 113. The vibration damping unit 110 can isolate external vibrations from being transmitted to the load 300, and when the load 300 vibrates, the vibration damping unit 110 can deform, absorbing the vibrations generated by the load 300, thereby reducing the vibration of the load 300 and improving its stability.

[0066] Specifically, see Figures 1-3 As shown, the bracket 113 includes a support portion 1131 and a connecting portion 1132. The support portion 1131 can connect the load 300. In this embodiment, when the load 300 needs to be connected to the support mechanism 200, the load 300 can be connected to the support portion 1131 by means of screwing, snap-fitting, etc. Since the bracket 113 is disposed on the support mechanism 200, the load 300 is indirectly connected to the support mechanism 200 through the bracket 113. The connecting portion 1132 is detachably connected to the vibration damping unit 110. In this embodiment, the connecting portion 1132 is in the shape of a hook, and the bracket 113 is hung on the support mechanism 200 through the connecting portion 1132. Of course, in other feasible embodiments, the connecting portion 1132 can also be other shapes. This application does not limit the specific shape of the connecting portion 1132.

[0067] Further, see Figure 2 and Figure 3 As shown, there are two supports 113, which are symmetrically arranged on opposite sides of the load-bearing mechanism 200. The two ends of the load 300 can be connected to the two supports 113 respectively. In this way, by connecting the two ends of the load 300 to the two supports 113 respectively, the support stability of the vibration damping mechanism 100 for the load 300 can be improved, further reducing the vibration of the load 300, and thus improving the stability of the load 300.

[0068] Additionally, see Figure 1 and Figure 2 As shown, this application also provides a shooting device 400. The shooting device 400 includes a support mechanism 200, a camera 410, and a vibration damping mechanism 100 as described above. The support mechanism 200 has an installation space 112, and can be a mobile platform such as an Automated Guided Vehicle (AGV), robot, or drone. The support mechanism 200 can drive the camera 410 to perform dynamic shooting operations such as aerial photography.

[0069] The vibration damping mechanism 100 includes multiple vibration damping units 110, which are all mounted on the support mechanism 200 by means of screws, snap-fits, or other methods, and are spaced apart in the mounting space 112. The camera 410 is detachably connected to the support mechanism 200 and is located in the mounting space 112. When the camera 410 is connected to the support mechanism 200, the outer contour of the camera 410 is in contact with all the vibration damping units 110.

[0070] The aforementioned imaging device 400 includes a vibration damping unit 110 that isolates vibrations from being transmitted to the camera 410. When the camera 410 vibrates, the vibration damping unit 110 deforms, absorbing the vibrations and thus reducing them, thereby improving the stability of the camera 410 during dynamic imaging operations. By setting different materials, outer contours, and / or temperature environments for some or all of the vibration damping units 110, the resonant frequency of the imaging device 400 can be adjusted, reducing the energy coupling effect generated during vibration and further improving the stability of the camera 410. Furthermore, multiple vibration damping units 110 can be arranged around the camera 410, reducing the overall size of the imaging device 400.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
