[0008] In some embodiments, the mounting structure is detachably connected to the bearing surface.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.
[0023] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0024] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.
[0025] In the following specific embodiments, the vibration damping and lifting device can be used to support any optical equipment, such as an optical radar, laser rangefinder, or optical theodolite. The vibration damping and lifting device can be applied to any load-bearing surface. For example, the vibration damping and lifting device can be fixed to the ground, to the subframe of a vehicle, or to a ship. The structure and function of the vibration damping and lifting device are described below with reference to various embodiments.
[0026] In some embodiments, such as Figure 1 As shown, the vibration damping lifting device 1 is used to support optical equipment. The vibration damping lifting device 1 includes: a lifting platform 10, a lifting assembly 20, and a vibration damping device 30. The lifting platform 10 has a bearing surface 11, which is used to support the optical equipment. In the use state, the bearing surface 11 is the top surface of the lifting platform 10.
[0027] The lifting assembly 20 is connected to the lifting platform 10 and is used to drive the lifting platform 10 to move up and down, thereby driving the optical equipment to move up and down. The lifting assembly 20 can be any component capable of lifting drive. For example, the lifting assembly 20 can be a drive cylinder, with multiple drive cylinders spaced apart and moving synchronously to drive the lifting platform 10 to move up and down. For example, the lifting assembly 20 can also include a motor and a lead screw transmission structure, with the motor driving multiple lead screw transmission structures to rotate synchronously, thereby driving the lifting platform 10 to move up and down. Driving the lifting platform 10 to move up and down via the lifting assembly 20 also facilitates maintenance personnel to inspect or maintain the optical equipment. For example, when maintenance or repair of the optical equipment is required, the lifting platform 10 can be lowered via the lifting assembly 20 to lower the optical equipment to a lower position, making it easier for maintenance personnel to inspect and maintain the optical equipment. For example, when the space above the optical equipment is narrow, the lifting platform 10 can also be lowered via the lifting assembly 20 to lower the optical equipment to a lower position, allowing maintenance and repair of the optical equipment without removing it from the lifting platform 10.
[0028] The vibration damping device 30 is located between the lifting platform 10 and the lifting assembly 20, and connects the lifting platform 10 and the lifting assembly 20. It can be understood that one part of the vibration damping device 30 is connected to the lifting platform 10, and the other part of the vibration damping device 30 is connected to the lifting assembly 20. When external excitation causes a tendency for relative motion between the lifting platform 10 and the lifting assembly 20, the vibration damping device 30 can, through its own elastic structure and damping structure, transform the short-term and large-amplitude impact motion between the lifting platform 10 and the lifting assembly 20 into a longer-term and smaller-amplitude damped vibration. That is, it achieves buffering and absorption of the impact load between the lifting platform 10 and the lifting assembly 20, reduces the impact of vibration on the optical equipment, extends the service life of the optical equipment, and also makes the data acquired by the optical equipment more accurate.
[0029] The lifting platform 10 also has a mounting structure 12 fixed to the bearing surface 11. The mounting structure 12 is connected to the vibration damping device 30 and is located above the bearing surface 11 so that the center of rigidity of the vibration damping device 30 is at the same height as the center of mass of the optical equipment and the lifting platform as a whole. This can be understood as providing installation space for the vibration damping device 30 by setting the mounting structure 12, thereby allowing the installation position of the vibration damping device 30 and the lifting platform 10 to be higher than the bearing surface 11. This allows the center of rigidity of the vibration damping device 30 to be at the same height as the center of mass of the optical equipment and the lifting platform as a whole. The center of mass of the optical equipment and the lifting platform as a whole can be understood as the center of mass of the overall structure formed by the optical equipment placed on the lifting platform. While connecting the vibration damping device 30 to the mounting structure 12, it is also necessary to avoid interference between the vibration damping device 30 and the lifting assembly 20 and the lifting platform. This can be achieved by extending the mounting structure 12 to the outside of the side of the lifting platform 10, so that the vibration damping device 30 and the lifting assembly 20 are at the same height. The lowering component 20 is located on the outside of the side of the lifting platform 10 to avoid the lifting platform 10. Alternatively, a clearance groove can be provided on the lifting platform 10 to allow the lifting platform 10 to avoid the vibration damping device 10 and the lifting component 20. At the same time, multiple mounting structures 12 are spaced apart, and each mounting structure 12 is connected to at least one vibration damping device 30. This allows the multiple vibration damping devices 30 to be spaced apart and their centers of rigidity to coincide with the center of mass of the optical equipment. It can be understood that, based on the fact that the centers of rigidity of the vibration damping devices 30 and the optical equipment are at the same height, multiple spaced vibration damping devices 30 form a discrete vibration damping system. Through the positional arrangement of each vibration damping device 30, the center of rigidity of the vibration damping system can coincide with the center of mass of the optical equipment and the lifting platform 10 as a whole, thereby enabling the vibration damping system to achieve a better vibration damping effect on the optical equipment. The principle of how the vibration damping system achieves a better vibration damping effect on the optical equipment will be explained below.
[0030] In related vibration damping lifting devices, the lifting assembly is directly manufactured below the lifting platform, and the vibration damping device is also located below the lifting platform. In this type of vibration damping lifting device, the center of rigidity of the vibration damping system formed by multiple vibration damping devices is located slightly below the lifting platform. The center of rigidity of this vibration damping system cannot coincide with the center of mass of the equipment carried on the lifting platform. The center of mass of the equipment is higher than the center of rigidity of the vibration damping system. When the lifting platform generates yaw vibration under external excitation, the equipment does not deflect around its own center of mass, but revolves around the center of rigidity of the vibration damping system, resulting in a larger displacement of the equipment. In the vibration damping lifting device 1 provided in this embodiment, by setting the installation structure 12, the center of rigidity of the vibration damping system formed by each vibration damping device 30 can coincide with the center of mass of the optical equipment and the lifting platform 10 as a whole. When the lifting platform 10 generates yaw motion under external excitation, the optical equipment can only deflect around its own center of mass by a small amplitude, thereby reducing the displacement of the optical equipment and thus reducing the impact of vibration on the optical equipment.
[0031] It should be noted that in related vibration damping and lifting devices, the supported equipment is directly supported above the support platform, thus making the center of mass of the equipment relatively close to the center of rigidity of the vibration system. The increase in vibration amplitude due to the misalignment of the center of mass and the center of rigidity is relatively small. Furthermore, general devices do not require high positional accuracy and have a certain degree of vibration resistance; therefore, the increase in vibration amplitude due to the misalignment of the center of mass and the center of rigidity can be ignored. However, the optical equipment supported in this embodiment is different from general equipment. Optical equipment requires high positional accuracy during operation, and the vibration resistance of the optical components within it is relatively low. This increase in vibration amplitude due to the misalignment of the center of mass and the center of rigidity may not only significantly affect the accuracy of data acquisition by the optical equipment but may even damage the optical components. In other words, the applicant only became aware of the importance of the misalignment of the center of mass and the center of rigidity because of the specific needs of this particular application. The technical problem caused by the misalignment of the center of mass and the center of rigidity is difficult for those skilled in the art to recognize based on general equipment. Furthermore, directly supporting the vibration damping device below the lifting platform facilitates its installation and prevents motion interference between the lifting assembly and the platform during lifting. If the vibration damping device is installed above the lifting platform, not only is an additional installation structure required, but the risk of motion interference between the lifting assembly and the platform also increases. Therefore, given that the relevant vibration damping lifting device does not have the technical problem caused by the misalignment of the center of mass and the center of rigidity, those skilled in the art would find it difficult to conceive of the need for significant modifications to the vibration damping lifting device, or of modifying it into a more costly structure with a risk of motion interference. In other words, those skilled in the art would find it difficult to conceive of the vibration damping lifting device 1 provided in this embodiment based on the relevant vibration damping lifting device.
[0032] This invention provides a vibration-damping lifting device for supporting optical equipment. The device includes: a lifting platform with a bearing surface for supporting the optical equipment; a lifting assembly connected to the lifting platform for driving its lifting motion; and a vibration-damping device located between and connecting the lifting platform and the lifting assembly. The lifting assembly drives the lifting platform to move the optical equipment up and down, while the vibration-damping device reduces the impact of vibration on the optical equipment. The lifting platform also has a mounting structure fixed to the bearing surface, positioned above the bearing surface. The mounting structure is connected to the vibration-damping device so that the center of rigidity of the vibration-damping device is higher than the bearing surface, thereby allowing... The center of rigidity of the vibration damping device is located at the same height as the center of mass of the optical equipment and the lifting platform as a whole. At the same time, there are multiple installation structures, which are spaced apart and each installation structure is connected to at least one vibration damping device. This ensures that the center of rigidity of the vibration damping device coincides with the center of mass of the optical equipment and the lifting platform as a whole. That is, by arranging the installation structures and vibration damping devices, the center of rigidity of the discrete vibration damping system formed by multiple vibration damping devices coincides with the center of mass of the optical equipment. When the lifting platform experiences polarization vibration, the optical equipment can deflect only around its own center of mass, reducing the vibration amplitude of the optical equipment. In other words, the vibration damping lifting device has better vibration damping capability, thereby reducing the impact of vibration on the optical equipment.
[0033] In some embodiments, such as Figure 2 As shown, the mounting structure 12 extends circumferentially around the bearing surface 11, that is, the mounting structure 12 forms a continuous structure around the outside of the bearing surface 11, thereby providing a larger installation space for the vibration damping device 30 and facilitating the installation of the vibration damping device 30; wherein, the mounting structure 12 includes a first part 121 and a second part 122, the first part 121 extends upward from the bearing surface 11, and the second part extends from the surface of the first part 122 in a direction away from the bearing surface 11, and the extension direction of the second part 122 is not parallel to the extension direction of the first part 121. Optionally, the extension direction of the second part 122 is parallel to the extension direction of the first part 121. The extension direction of part 121 is vertical, that is, the second part 122 extends horizontally, so that the second part 122 extends horizontally to the outer side of the lifting platform 10, and the second part 122 is higher than the bearing surface 11, so that the vibration damping device 30 and the lifting assembly 20 can be connected to the mounting structure 12 on the outer side of the lifting platform 10. That is, under the premise of reducing the interference between the vibration damping device 30 and the lifting assembly 20 and the lifting platform 10, the rigid center of the vibration damping device 30 can be higher than the bearing surface 11, so that the rigid center of the vibration damping system formed by each vibration damping device 30 can coincide with the center of mass of the optical equipment.
[0034] In some embodiments, such as Figure 1As shown, the mounting structure 12 is fixed above the bearing surface 11, and the mounting structure 12 surrounds and forms the mounting space 123. The vibration damping device 30 is located in the mounting space 123 and connected to the mounting structure 12. Meanwhile, the lifting platform 10 has a clearance groove 13 for the lifting assembly 20 to pass through. The clearance groove 13 is connected to the mounting space 123. By setting the clearance groove 13 connected to the mounting space 123, the lifting assembly 20 can pass directly through the clearance groove 13 from below the lifting platform 10 and extend into the mounting space 123 so as to connect with the vibration damping device 30 in the mounting space 123. This allows the vibration damping device 30 to be located above the bearing surface 11 and reduces interference between the lifting platform 10 and the lifting assembly 20, while reducing the lateral size of the vibration damping lifting device 1.
[0035] In some embodiments, such as Figure 1 As shown, the mounting structure 12 is detachably connected to the bearing surface 11. When the vibration damping device 30 needs to be maintained or replaced, the lifting platform 10 can be temporarily supported, and the mounting structure 12 can be separated from the bearing surface 11 to expose the vibration damping device 30 that needs to be replaced or maintained. This allows the vibration damping device 30 to be replaced and maintained without having to completely dismantle the lifting platform 10.
[0036] In some embodiments, combined with Figure 1 and Figure 3 The lifting assembly 20 includes a column 21 and a sleeve 22. The end of the column 21 is connected to the vibration damping device 30. The sleeve 22 is fitted around the outside of the column and slidably connected to the column 21. The inner wall of the sleeve 22 extends vertically, thereby providing a motion guide for the column 21 and restricting the movement of the column 21 to the vertical direction. In the vertical direction, the outer contour of the clearance groove 13 is larger than the outer contour of the sleeve 22. It can be understood that the outer contour of the sleeve 22 forms a first projection on the bearing surface 11 in the vertical direction, and the outer contour of the clearance groove 13 forms a second projection on the bearing surface 11 in the vertical direction. The first projection is surrounded inside the second projection. Thus, when the column 21 drives the lifting platform 10 to move up and down, the top of the sleeve 22 can enter the clearance groove 13 without colliding with the lifting platform 10, that is, reducing the possibility of motion interference between the sleeve 22 and the lifting platform 10.
[0037] In some embodiments, combined with Figure 3 and Figure 4 ,like Figure 4 As shown, the lifting assembly 20 includes multiple components, and each lifting assembly 20 is arranged at intervals around the lifting platform. This can be understood as multiple lifting assemblies 20 being arranged at intervals in at least two different directions, thereby achieving stable support for the lifting platform 10. Simultaneously, as... Figure 3As shown, the lifting assembly 20 includes a column 21, a sleeve 22, a reducer 23, a mounting plate 24, and a transmission structure 26. The end of the column 21 is connected to the lifting platform 10 to drive the lifting platform 10 to move up and down. The sleeve 22 is sleeved on the outside of the column 21 and provides motion guidance for the column 21. The sleeve 22 is mounted on the mounting plate 24. The reducer 23 is mounted on the mounting plate 24 and connected to the column 21. The reducer 23 is used to provide a large transmission ratio. After the rotary drive device is connected to the reducer 23, the reducer 23 can improve the driving capability of the rotary drive device on the column 21 through the reduction torque increase effect.
[0038] The vibration damping lifting device 1 also includes a motor 40, the output shaft of which is connected to a reducer 23 of multiple lifting components 20 to synchronously drive the columns 21 of the multiple lifting components 20 to perform lifting movements.
[0039] In some embodiments, such as Figure 3 As shown, in the thickness direction of the mounting plate 24, the reducer 23 and the transmission structure 26 are located on both sides of the mounting plate 24. The reducer 23 passes through the mounting plate 24 and is connected to the transmission structure 26. The transmission structure 26 is used to convert the rotational motion of the motor 40 into linear motion and transmit the power to the column 21, thereby driving the column 21 to move vertically up and down. The transmission structure 26 can be, for example, a gear and rack structure or a threaded transmission structure. The transmission structure 26 is connected to the mounting plate 24 and is located on the opposite side of the mounting plate 24 from the sleeve 22. For example, the sleeve 22 is located above the mounting plate 24, and the transmission structure 26 is located below the mounting plate 24, thereby making full use of the installation space of the mounting plate 24 and making the structure of the lifting assembly 20 more compact. Optionally, the lifting assembly 20 also includes a transmission housing, which is fixed to the bottom of the mounting plate 24 and surrounds the mounting plate 24 to form a transmission cavity. The transmission structure 26 is located in the transmission cavity, so that the transmission structure 26 is a closed transmission, which reduces the impact of the external environment on the service life of the transmission structure 26 and also facilitates the lubrication of the transmission structure 26.
[0040] In some embodiments, combined with Figure 3 and Figure 4 , Figure 1 The vibration damping lifting device 1 also includes a support platform 50, which has a support surface 51. The mounting plate 24 is fixed to the support surface 51, thereby reliably supporting the transmission lifting assembly 20 through the support surface 51. At the same time, the support surface 51 is recessed to form a receiving cavity 52, and the transmission structure 26 is located in the receiving cavity 52. It can be understood that while the mounting plate 24 is reliably supported by the support surface 51, the transmission structure 26 located below the mounting plate 24 is avoided by the receiving cavity 52, so as to prevent interference between the transmission structure 26 and the support surface 51.
[0041] In some embodiments, for ease of explanation, a first direction and a second direction are defined below. Both the first direction and the second direction are perpendicular to the vertical direction, and the first direction is perpendicular to the second direction. Meanwhile, the axis parallel to the first direction and passing through the center of mass of the optical device is called the longitudinal axis, and the axis parallel to the second direction and passing through the center of mass of the optical device is called the transverse axis. The motion of the optical device deflecting about the longitudinal axis is called the tilt motion, and the motion of the optical device deflecting about the transverse axis is called the pitch motion.
[0042] like Figure 4 As shown, in the first direction (the first direction is as follows) Figure 4 As indicated by the solid arrows in the middle, multiple lifting components 20 are located at the first end of the lifting platform 10, and multiple lifting components 20 are located at the second end of the lifting platform 10 opposite to the first end. By setting lifting components 20 at both ends of the lifting platform 10 in the first direction, the pitch angle of the optical device can be controlled by the lifting components 20. Moreover, through the vibration damping device 30 connected to the lifting components 20, the pitch vibration of the optical device can be buffered and absorbed more effectively, reducing the amplitude of the pitch vibration of the optical device. At the same time, at the first end of the lifting platform 10, multiple lifting components 20 are located along the second direction (the second direction is as follows). Figure 4 (As shown by the dashed arrow in the middle) The end lifting group is arranged at intervals to provide more reliable support for the first end of the lifting platform 10 and achieve a better vibration reduction effect for the first end. Moreover, the output shaft of one of the multiple motors 40 extends along the second direction and is connected to each lifting component 20 in the end lifting group. Thus, one motor 40 can drive each lifting component 20 in the end lifting group at the same time, which improves the vibration reduction effect and reduces the number of motors 40 required.
[0043] In some embodiments, such as Figure 4 As shown, at the second end of the lifting platform 10, multiple lifting components 20 are spaced apart along the first direction to form a side lifting group, and multiple side lifting groups along the second direction are respectively located at both ends of the lifting platform 10. Thus, the tilt angle of the optical device can be controlled by the side lifting groups located at both ends of the second direction. Moreover, the vibration damping device 30 connected to the lifting component 20 can more fully buffer and absorb the tilt vibration of the optical device, reducing the amplitude of the tilt vibration of the optical device. At the same time, the output shaft of one of the multiple motors 40 extends along the first direction and is connected to each lifting component 20 in a side lifting group. Thus, each lifting component 20 in a side lifting group can be driven by one motor 40, which improves the vibration damping effect and reduces the number of motors 40 required.
[0044] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
