[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The various specific technical features in the various embodiments described in the specific implementation methods 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 the present invention will not be described separately.

[0023] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0024] In addition, it should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the following description, the terms "first\second\..." involved are merely used to distinguish different objects, and do not indicate that the objects have the same or related points. It should be understood that the directions described by the directions nouns such as "above", "below", "inside" and "outside" involved are all directions in normal use.

[0025] In the following specific implementations, the vibration reduction lifting device can be used to carry any optical device, such as an optical radar, a laser rangefinder or an optical theodolite. The vibration reduction lifting device can be applied to any bearing surface. For example, the vibration reduction lifting device can be fixed to the ground, the vibration reduction lifting device can also be fixed to the subframe of a vehicle, and the vibration reduction lifting device can also be fixed to a ship. The structure and function of the vibration reduction lifting device are exemplarily described below in combination with various embodiments.

[0026] In some embodiments, Figure 1 As shown, the vibration reduction lifting device 1 is used to carry optical equipment, and the vibration reduction lifting device 1 includes: a lifting platform 10, a lifting assembly 20 and a vibration reduction device 30. The lifting platform 10 has a bearing surface 11, and the bearing surface 11 is used to carry the optical equipment. When in use, 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 perform lifting motion, thereby driving the optical device to perform lifting motion. The lifting assembly 20 can be any assembly that can realize lifting drive. For example, the lifting assembly 20 can be a driving cylinder, and multiple driving cylinders are arranged at intervals and move synchronously, thereby driving the lifting platform 10 to perform lifting motion. For example, the lifting assembly 20 can also include a motor and a screw transmission structure, and the motor drives multiple screw transmission structures to rotate synchronously, thereby driving the lifting platform 10 to perform lifting motion. The lifting assembly 20 drives the lifting platform 10 to drive the optical device to perform lifting motion, which can also facilitate the maintenance personnel to inspect or maintain the optical device. For example, when the optical device needs to be repaired or maintained, the lifting assembly 20 drives the lifting platform 10 to descend so that the optical device descends to a lower position, thereby facilitating the maintenance personnel to inspect and maintain the optical device. For example, when the top space of the optical device is relatively narrow, the lifting assembly 20 can also drive the lifting platform 10 to descend, thereby descending the optical device to a lower position, so that the optical device can be repaired and maintained without removing the optical device from the lifting platform 10.

[0028] The vibration reduction 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 a part of the vibration reduction device 30 is connected to the lifting platform 10, and the other part of the vibration reduction device 30 is connected to the lifting assembly 20. When external excitation causes a tendency for relative movement between the lifting platform 10 and the lifting assembly 20, the vibration reduction device 30 can convert the short-term and large-amplitude impact movement between the lifting platform 10 and the lifting assembly 20 into a damped vibration with a longer time and a smaller amplitude through its own elastic structure and damping structure, that is, the impact load between the lifting platform 10 and the lifting assembly 20 is buffered and absorbed, the influence of vibration on the optical device is reduced, the service life of the optical device is extended, and the data acquired by the optical device can be made more accurate.

[0029] The lifting platform 10 further comprises a mounting structure 12 fixed to the bearing surface 11, the mounting structure 12 is connected to the vibration reduction device 30, and the mounting structure 12 is located above the bearing surface 11, so that the rigid center of the vibration reduction device 30 is at the same height as the center of mass of the optical device and the lifting platform as a whole. It can be understood that by providing the mounting structure 12 to provide an installation space for the vibration reduction device 30, the installation position of the vibration reduction device 30 and the lifting platform 10 can be higher than the bearing surface 11, thereby allowing the rigid center of the vibration reduction device 30 to be at the same height as the center of mass of the optical device and the lifting platform as a whole, wherein the center of mass of the optical device and the lifting platform as a whole can be understood as the center of mass of the overall structure formed by placing the optical device on the lifting platform, while the vibration reduction device 30 is connected to the mounting structure 12, it is also necessary to avoid interference between the vibration reduction device 30 and the lifting assembly 20 and the lifting platform, the mounting structure 12 can be extended to the outside of the side of the lifting platform 10 to allow the vibration reduction device 30 and the lifting assembly 20 to be at the same height. The lowering component 20 is located outside the side of the lifting platform 10 to avoid the lifting platform 10. The lifting platform 10 can also avoid the vibration reduction device 10 and the lifting component 20 by setting an avoidance groove on the lifting platform 10. At the same time, multiple mounting structures 12 are arranged at intervals and each mounting structure 12 is respectively connected to at least one vibration reduction device 30, so that multiple vibration reduction devices 30 are arranged at intervals and the rigid center of the vibration reduction device 30 coincides with the center of mass of the optical device. It can be understood that on the basis of making the rigid center of the vibration reduction device 30 and the optical device be located at the same height, a discrete vibration reduction system is formed by multiple vibration reduction devices 30 arranged at intervals, and the position arrangement of each vibration reduction device 30 can make the rigid center of the vibration reduction system coincide with the center of mass of the optical device and the lifting platform 10 as a whole, so that the vibration reduction system can have a better vibration reduction effect on the optical device. The following is an explanation of the principle of the vibration reduction system achieving a better vibration reduction effect on the optical device.

[0030] In the relevant vibration-damping lifting device, the lifting assembly is directly manufactured under the lifting platform and the vibration-damping device is also located under the lifting platform. The center of rigidity of the vibration-damping system formed by multiple vibration-damping devices in this vibration-damping lifting device is located slightly lower than the lifting platform. The center of rigidity of the 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, thereby causing the equipment to generate a larger displacement. In the vibration-damping lifting device 1 provided in this embodiment, an installation structure 12 is provided so that 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 device and the lifting platform 10 as a whole. When the lifting platform 10 generates yaw motion under external excitation, the optical device can only deflect slightly around its own center of mass, thereby reducing the displacement of the optical device, thereby reducing the impact of vibration on the optical device.

[0031] It should be noted that in the relevant vibration-damping lifting device, the carried equipment is directly carried on the top of the carrying platform, so that the center of mass of the equipment is close to the center of rigidity of the vibration system. The increase in vibration amplitude caused by the misalignment of the center of mass and the center of rigidity is relatively small, and general devices do not have high requirements for position accuracy and have a certain vibration resistance. The increase in vibration amplitude caused by the misalignment of the center of mass and the center of rigidity can be ignored. However, the optical device carried by this embodiment is different from general equipment. The optical device requires very high position accuracy during operation, and the vibration resistance of the optical devices in the optical device is also low. This increase in vibration amplitude caused by the misalignment of the center of mass and the center of rigidity may not only have a significant impact on the accuracy of data acquisition by the optical device, but may even cause damage to the optical devices in the optical device. That is, the applicant was able to realize the difference between the center of mass and the center of rigidity based on the special needs of special application objects such as optical devices. It is difficult for technical personnel in this field to realize the technical problems caused by the misalignment of the center of mass and the center of rigidity based on general equipment; at the same time, directly supporting the vibration damping device under the lifting platform is convenient for the installation of the vibration damping device, and there will be no motion interference between the lifting component and the lifting platform when the lifting component is lifted. If the installation position of the vibration damping device is set above the lifting platform, not only is it necessary to set up an additional installation structure, but also the risk of motion interference between the lifting component and the lifting platform is increased. Therefore, on the basis that there is no technical problem caused by the misalignment of the center of mass and the center of rigidity in the relevant vibration damping lifting device, it is difficult for technical personnel in this field to think of the need to modify the vibration damping lifting device to a greater extent based on the relevant vibration damping lifting device, and to modify the vibration damping lifting device into a structure with higher cost and risk of motion interference. That is, it is difficult for technical personnel in this field to think of the vibration damping lifting device 1 provided in this embodiment based on the relevant vibration damping lifting device.

[0032] The embodiment of the present invention provides a vibration-damping lifting device, which is used to carry optical equipment. The vibration-damping lifting device includes: a lifting platform having a bearing surface for carrying the optical equipment, a lifting assembly connected to the lifting platform for driving the lifting platform to move up and down, and a vibration-damping device located between the lifting platform and the lifting assembly and connecting the lifting platform and the lifting assembly. The lifting platform can be driven by the lifting assembly to drive the optical equipment to move up and down, and the vibration-damping device can reduce the influence of vibration on the optical equipment. The lifting platform also has a mounting structure fixed to the bearing surface, the mounting structure is located above the bearing surface, and the mounting structure is connected to the vibration-damping device so that the rigidity center of the vibration-damping device can be higher than the bearing surface, thereby allowing The rigid center of the vibration reduction device is located at the same height as the center of mass of the optical device and the lifting platform as a whole. At the same time, there are multiple mounting structures, and the multiple mounting structures are arranged at intervals and each mounting structure is connected to at least one vibration reduction device, so that the rigid center of the vibration reduction device coincides with the center of mass of the optical device and the lifting platform as a whole. That is, by arranging the positions of the mounting structures and the vibration reduction devices, the rigid center of the discrete vibration reduction system formed by the multiple vibration reduction devices coincides with the center of mass of the optical device. When the lifting platform undergoes polarization vibration, the optical device can only deflect around its own center of mass, thereby reducing the vibration amplitude of the optical device, that is, the vibration reduction lifting device has better vibration reduction ability, thereby reducing the influence of vibration on the optical device.

[0033] In some embodiments, Figure 2 As shown, the mounting structure 12 extends around the circumference of the bearing surface 11, that is, the mounting structure 12 surrounds the outside of the bearing surface 11 to form a continuous structure, thereby providing a larger installation space for the vibration reduction device 30, which is convenient for the installation of the vibration reduction device 30; wherein the mounting structure 12 includes a first portion 121 and a second portion 122, the first portion 121 extends upward from the bearing surface 11, the second portion extends from the surface of the first portion 122 in a direction away from the bearing surface 11, and the extension direction of the second portion 122 is not parallel to the extension direction of the first portion 121, and optionally, the extension direction of the second portion 122 is parallel to the extension direction of the first portion 121. The extension direction of the portion 121 is vertical, that is, the second portion 122 extends in the horizontal direction, so that the second portion 122 extends in the horizontal direction to the outside of the side of the lifting platform 10, and the second portion 122 is higher than the bearing surface 11, so that the vibration reduction device 30 and the lifting assembly 20 can be connected to the mounting structure 12 on the outside of the side of the lifting platform 10, that is, under the premise of reducing the interference between the vibration reduction device 30 and the lifting assembly 20 and the lifting platform 10, the center of rigidity of the vibration reduction device 30 can be higher than the bearing surface 11, and then the center of rigidity of the vibration reduction system formed by each vibration reduction device 30 can coincide with the center of mass of the optical device.

[0034] In some embodiments, Figure 1As shown, the mounting structure 12 is fixed above the bearing surface 11, and the mounting structure 12 surrounds and forms an installation space 123. The vibration reduction device 30 is located in the installation space 123 and is connected to the mounting structure 12. At the same time, the lifting platform 10 has an avoidance groove 13 for the lifting component 20 to pass through, and the avoidance groove 13 is connected to the installation space 123. By providing the avoidance groove 13 connected to the installation space 123, the lifting component 20 can directly pass through the avoidance groove 13 from the bottom of the lifting platform 10 and extend into the installation space 123, so as to be connected to the vibration reduction device 30 in the installation space 123, thereby allowing the vibration reduction device 30 to be located above the bearing surface 11 and reducing the interference between the lifting platform 10 and the lifting component 20, while reducing the lateral size of the vibration reduction lifting device 1.

[0035] In some embodiments, 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 then the mounting structure 12 and the bearing surface 11 can be separated to expose the vibration damping device 30 that needs to be replaced or maintained, thereby enabling the vibration damping device 30 to be replaced and maintained without dismantling the lifting platform 10 as a whole.

[0036] In some embodiments, in combination 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 reduction device 30, the sleeve 22 is sleeved on the outside of the column and slidably connected to the column 21, and the inner wall of the sleeve 22 extends in the vertical direction, so that the sleeve 22 provides a movement guide for the column 21, and the movement of the column 21 is limited in the vertical direction; wherein, perpendicular to the vertical direction, the size of the outer contour of the avoidance groove 13 is larger than the size of the outer contour of the sleeve 22, which can be understood as the outer contour of the sleeve 22 forms a first projection on the bearing surface 11 along the vertical direction, and the outer contour of the avoidance groove 13 forms a second projection on the bearing surface 11 along the vertical direction, and the first projection is surrounded by the second projection. When the column 21 drives the lifting platform 10 to move up and down, the top of the sleeve 22 can enter the avoidance groove 13 without colliding with the lifting platform 10, that is, the possibility of motion interference between the sleeve 22 and the lifting platform 10 is reduced.

[0037] In some embodiments, in combination Figure 3 and Figure 4 ,like Figure 4 As shown, the lifting assembly 20 includes a plurality of lifting assemblies 20, and each lifting assembly 20 is arranged at intervals around the lifting platform. It can be understood that the plurality of lifting assemblies 20 are arranged at intervals in at least two different directions, so as to achieve stable support for the lifting platform 10. 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 a movement guide for the column 21. The sleeve 22 is installed on the mounting plate 24. The reducer 23 is installed on the mounting plate 24 and connected to the column 21. The reducer 23 is used to provide a larger transmission ratio. After the rotary drive device is connected to the reducer 23, the reducer 23 can improve the driving ability of the rotary drive device on the column 21 through the deceleration and torque increase effect.

[0038] The vibration-damping lifting device 1 further includes a motor 40 , the output shaft of which is connected to the reducers 23 of the plurality of lifting assemblies 20 to synchronously drive the columns 21 of the plurality of lifting assemblies 20 to perform lifting motions.

[0039] In some embodiments, 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, so as to drive the column 21 to move up and down in a vertical direction, the transmission structure 26 can be, for example, a gear rack structure, or a threaded transmission structure; the transmission structure 26 is connected to the mounting plate 24, and is located on the other side of the mounting plate 24 opposite to the sleeve 22, as shown 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 fully utilizing 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 surrounded by 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 influence of the external environment on the service life of the transmission structure 26 and can also facilitate lubrication of the transmission structure 26.

[0040] In some embodiments, in combination Figure 3 and Figure 4 , Figure 1 The vibration reduction 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, so that the transmission lifting assembly 20 is reliably supported by the support surface 51. At the same time, the support surface 51 is concave to form an accommodating cavity 52, and the transmission structure 26 is located in the accommodating 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 accommodating cavity 52 to avoid 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, wherein both the first direction and the second direction are perpendicular to the vertical direction, and the first direction is perpendicular to the second direction. At the same time, the axis parallel to the first direction and passing through the center of mass of the optical device is called the longitudinal axis, the axis parallel to the second direction and passing through the center of mass of the optical device is called the transverse axis, the movement of the optical device deflecting around the longitudinal axis is called the roll motion, and the movement of the optical device deflecting around the transverse axis is called the pitch motion.

[0042] like Figure 4 As shown, in the first direction (the first direction is as Figure 4 The plurality of lifting assemblies 20 are located at the first end of the lifting platform 10, and the plurality of lifting assemblies 20 are located at the second end of the lifting platform 10 opposite to the first end. By arranging the lifting assemblies 20 at the two ends of the lifting platform 10 in the first direction, the pitch angle of the optical device can be controlled by the lifting assemblies 20, and the vibration reduction device 30 connected to the lifting assemblies 20 can also more fully buffer and absorb the pitch vibration of the optical device, thereby reducing the amplitude of the pitch vibration of the optical device. At the same time, at the first end of the lifting platform 10, the plurality of lifting assemblies 20 are arranged along the second direction (the second direction is as shown in FIG. 1 ). Figure 4 The first end of the lifting platform 10 is supported more reliably and a better vibration reduction effect can be achieved on the first end. Moreover, the output shaft of one of the multiple motors 40 extends along the second direction and is simultaneously connected to each lifting component 20 in the end lifting group, so that each lifting component 20 in the end lifting group is driven simultaneously by one motor 40, thereby improving the vibration reduction effect and reducing the number of required motors 40.

[0043] In some embodiments, Figure 4 As shown, at the second end of the lifting platform 10, a plurality of lifting components 20 are arranged at intervals along the first direction to form a side lifting group, and a plurality of side lifting groups are respectively located at both ends of the lifting platform 10 along the second direction, so that the roll angle of the optical device is controlled by the side lifting groups located at both ends of the second direction, and, through the vibration reduction device 30 connected to the lifting component 20, the roll vibration of the optical device can be more fully buffered and absorbed, thereby reducing the amplitude of the roll vibration of the optical device; at the same time, the output shaft of one of the plurality of motors 40 extends along the first direction and is connected to each lifting component 20 in a side lifting group, so that each lifting component 20 in a side lifting group can be driven by one motor 40, thereby improving the vibration reduction effect and reducing the number of required motors 40.

[0044] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
