Description

Floating docking mechanism based on adaptive elastic components Technical Field

[0001] This invention relates to the field of floating docking mechanisms, and more particularly to a floating docking mechanism based on an adaptive elastic component. Background Technology

[0002] In the fields of heavy equipment such as aerospace and marine equipment, large connectors (such as high-voltage electrical connectors, signal connectors, and water connectors) are core components for realizing power transmission, signal interaction, and energy cooling. Their mating performance directly determines the operational stability of the equipment. Due to space constraints and the trend towards integration, multiple large connectors of different types are usually integrated onto a single equipment panel. This presents challenges such as large mating loads, complex mating environments (vibration, shock), and high precision requirements for mating dimensions (coaxiality ≤ 1.0 mm). These challenges create an urgent need for the mating mechanism to have high load-bearing capacity and adaptive compensation capabilities for deviations.

[0003] Currently, large connector mating technologies are mainly divided into two categories: rigid mating and floating mating with simple elastic structures. Pure rigid mating is usually done manually and relies entirely on the accuracy of the installation reference, resulting in low mating efficiency. Simple elastic structure mating solves some of the floating adaptation problems, but it has drawbacks such as low load capacity and limited compensation degrees of freedom. Summary of the Invention

[0004] To address the aforementioned issues, this invention combines and connects the adaptive spring assembly, the power plate assembly, and the floating plate assembly, enabling the floating docking mechanism to possess multi-degree-of-freedom and large-tolerance floating docking capabilities. Furthermore, through the free combination of the adaptive spring assembly, it can achieve large load and variable stiffness bearing capacity, thus solving the problems of difficult compensation for floating errors, low docking accuracy and efficiency, and insufficient large load bearing capacity of traditional large connectors when docking under conditions such as vibration.

[0005] This invention provides a floating docking mechanism based on adaptive elastic components. The floating docking mechanism includes: a floating plate assembly with docking surfaces and mounting surfaces on both sides along the thickness direction of the floating plate; and an adaptive elastic component, wherein multiple adaptive elastic components are spaced apart and connected to the mounting surfaces. Each adaptive elastic component includes: an elastic positioning seat fixedly connected to the mounting surface; an upper elastic member with one end connected to the elastic positioning seat and the other end forming a first mounting end; and a lower elastic member with one end connected to the elastic positioning seat and the other end forming a second mounting end, the second mounting end being spaced apart from the first mounting end. The floating docking mechanism further includes: a power plate assembly located between the first mounting end and the second mounting end, the power plate assembly being fixedly connected to both the first and second mounting ends. The elastic positioning seat is movable relative to the power plate assembly in a direction perpendicular to the thickness of the floating plate assembly.

[0006] In some embodiments, the elastic positioning seat includes: a first upper connecting portion connected to the upper elastic member and fixedly connected to the mounting surface; a first lower connecting portion connected to the lower elastic member; and a first side connecting portion for connecting the first upper connecting portion and the first lower connecting portion, wherein the first side connecting portion is located outside the power plate assembly and spaced apart from the power plate assembly in a direction perpendicular to the thickness of the floating plate assembly.

[0007] In some embodiments, the elastic positioning seat includes: a second upper connecting portion connected to the upper elastic member and fixedly connected to the mounting surface; a second lower connecting portion connected to the lower elastic member; and a second side connecting portion for connecting the second upper connecting portion and the second lower connecting portion; wherein the floating plate assembly has a first clearance hole, the second side connecting portion passes through the first clearance hole, and in a direction perpendicular to the thickness of the floating plate assembly, the second side connecting portion is spaced apart from the inner wall of the first clearance hole.

[0008] In some embodiments, the floating docking mechanism further includes: a first positioning boss, fixedly connected to the elastic positioning seat and located inside the upper elastic member; and a second positioning boss, fixedly connected to the elastic positioning seat, located below the first positioning boss and inside the lower elastic member.

[0009] In some embodiments, the floating docking mechanism further includes a positioning post, the two ends of which are respectively connected to the first positioning boss and the second positioning boss; the adaptive elastic component further includes a power end mounting base, the power end mounting base is fixedly connected to the first mounting end, the power end mounting base is fixedly connected to the second mounting end, and the power end mounting base is fixedly connected to the power plate assembly; the power end mounting base has a second clearance hole, and the positioning post is located inside the second clearance hole.

[0010] In some embodiments, the floating docking mechanism further includes a buffer anti-collision sleeve, which is fitted over the outside of the positioning post.

[0011] In some embodiments, each of the adaptive elastic components is centrally symmetrically distributed with respect to the floating plate assembly.

[0012] In some embodiments, the power plate assembly includes: a floating end connection portion, fixedly connected to the upper elastic member and the lower elastic member; and a drive source connection portion, fixedly connected to the floating end connection portion and used for connection to a drive source.

[0013] In some embodiments, the floating plate assembly includes: a floating plate having the mounting surface and the mating surface; and guide pins extending from the mating surface; wherein the mating surface has a plurality of guide pins, each of the guide pins being symmetrically distributed along the geometric center of the floating plate.

[0014] In some embodiments, the end of the guide pin extending out of the mating surface forms a guide surface, and the cross-sectional area of ​​the portion of the guide pin having the guide surface decreases along the direction in which the guide pin extends out of the mating surface.

[0015] By setting adaptive elastic components, the floating docking mechanism can automatically compensate for lateral and longitudinal errors generated during docking. The risk of local overload can be reduced by multiple adaptive elastic components sharing the load. At the same time, by setting the elastic elements of the adaptive elastic components as separate upper and lower elastic element structures, the lateral stability of the adaptive elastic components is increased while allowing the floating docking mechanism to compensate for lateral errors. In addition, with the elastic positioning seat that can generate lateral movement with the power plate assembly, the risk of motion interference between the adaptive elastic components and the power plate assembly is reduced on the basis that the above functions can be realized.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] In the following specific embodiments, the floating docking mechanism based on the adaptive elastic component can be used for any heavy-duty docking equipment. The adaptive elastic component can compensate for floating errors during the docking process of heavy-duty equipment. The compensation includes axial error and lateral error. Moreover, the adaptive elastic component can maintain lateral stability under heavy-duty conditions, reducing the risk of lateral instability under heavy-duty conditions. The structure of the floating docking mechanism based on the adaptive elastic component will be illustrated below with reference to various embodiments.

[0023] In some embodiments, as shown in FIG1, the floating docking mechanism includes: a floating plate assembly 30, an adaptive elastic assembly 10, and a power plate assembly 20. A mating surface and a mounting surface are formed on both sides along the thickness direction of the floating plate assembly 30. The mating surface is used to dock with an external heavy-duty device, and the mounting surface is used to connect with the adaptive elastic component 10. There are multiple adaptive elastic components 10, which are spaced apart and fixedly connected to the mounting surface. During the docking process, the axial elastic deformation of each adaptive elastic component 10 enables the floating plate assembly 30 to produce an adaptive sway, so that the mating surface can fully fit with the external heavy-duty device, thus achieving axial error compensation. At the same time, the lateral elastic deformation of each adaptive elastic component 10 enables the floating plate assembly 30 to produce an adaptive lateral movement, so that the mating surface can face the external heavy-duty device. When the mating surface has a docking structure, the docking structure can also cooperate with the docking structure of the external heavy-duty device, thus achieving lateral error compensation. That is, multiple degrees of freedom error compensation is achieved, wherein the axial direction is parallel to the thickness direction of the floating plate assembly 30, and the lateral direction is perpendicular to the thickness direction of the floating plate assembly 30.

[0024] The adaptive elastic component 10 can not only achieve multi-degree-of-freedom error compensation, but also improve the load-bearing capacity of the floating docking mechanism. Specifically, since the floating docking mechanism is used to support external heavy-duty devices, under heavy-duty conditions, it is necessary not only to avoid the adaptive elastic component 10 from yielding deformation or structural damage in the axial direction, but also to avoid the adaptive elastic component 10 from lateral instability in the transverse direction. The specific structure of the adaptive elastic component 10 and the way to improve lateral stability are illustrated below.

[0025] As shown in Figure 2, the adaptive elastic component 10 includes an elastic positioning seat 11, an upper elastic member 16, and a lower elastic member 15. The elastic positioning seat 11 is the mounting surface of the floating plate assembly 30; one end of the upper elastic member 16 is connected to the elastic positioning seat 11, and the other end of the upper elastic member 16 forms a first mounting end; one end of the lower elastic member 15 is connected to the elastic positioning seat 11, and the other end of the lower elastic member 15 forms a second mounting end, with the first mounting end and the second mounting end spaced apart; simultaneously, the power plate assembly 20 is located between the first mounting end and the second mounting end, and the power plate assembly is fixedly connected to the first mounting end and the second mounting end, that is, the power plate assembly 20 is fixed between two spaced elastic members, and the floating plate assembly 30 is connected via the upper elastic member 11. The elastic element 16 is fixedly connected to the upper surface of the power plate assembly 20, and the floating plate assembly 30 is fixedly connected to the lower surface of the power plate assembly 20 via the lower elastic element 15. This can be understood as follows: the elastic positioning seat 11 allows the two elastic elements to be fixed to both sides of the power plate assembly 20, enabling the elastic force of the two elastic elements to be transmitted to the floating plate assembly 30. Simultaneously, by using two separate elastic elements instead of a single elastic element, the length of a single elastic element is shortened, thereby increasing the risk of lateral instability in that elastic element. For example, for a spring fixed at both ends, the critical pressure for lateral instability is: in, Let E be the critical pressure, E be the elastic modulus of the elastic element, and I be the moment of inertia of the elastic element. Let be the length of the elastic element. With the material and cross-sectional shape of the elastic element remaining unchanged, the elastic element is divided into two elastic elements fixed at both ends. The length of each elastic element is half the length of the original elastic element. Then, the critical pressure for lateral instability of each shortened elastic element is 4 times the original, and the total critical pressure for lateral instability of the two shortened elastic elements is 8 times the original. It can be seen that using a split elastic element greatly increases the lateral stability of the adaptive elastic component.

[0026] Furthermore, since the elastic positioning seat 11 needs to be fixedly connected to the upper elastic element 16 and the lower elastic element 15 on both sides of the power plate assembly 20, and the elastic positioning seat 11 needs to move laterally together with the floating plate assembly 30, it is necessary to enable the elastic positioning seat 11 and the power plate assembly 20 to move relative to each other laterally to reduce the risk of interference between the elastic positioning seat 11 and the floating plate assembly 30 during lateral movement. It should be noted that the structure of this elastic positioning seat 11 is based on the concept of a split elastic element. It is precisely because of this structural design that the integral elastic structure can be replaced with a split elastic structure. The combination of these two technical features can achieve the technical problem that this embodiment wants to solve. The following are different ways to enable the elastic positioning seat 11 and the power plate assembly 20 to move relative to each other laterally. Those skilled in the art should understand that the lateral relative movement of the elastic positioning seat 11 and the power plate assembly 20 can also be achieved in different ways.

[0027] For example, as shown in FIG2, the elastic positioning seat 11 includes a first upper connecting portion 1101, a first lower connecting portion 1102, and a first side connecting portion 1103. The first upper connecting portion 1101 is connected to the upper elastic member 16 and fixedly connected to the mounting surface of the floating plate assembly 30. The first lower connecting portion 1102 is connected to the lower elastic member 15. The first side connecting portion 1103 is used to connect the first upper connecting portion 1101 and the first lower connecting portion 1102. In the thickness direction (lateral direction) perpendicular to the floating plate assembly 30, the first side connecting portion 1103 is located outside the power plate assembly 20 and spaced apart from the power plate assembly 20. It can be understood that the first side connecting portion 1103 passes around the power plate assembly 20 from the outside of the power plate assembly 20 so that the elastic positioning seat 11 can move laterally relative to the power plate assembly 20.

[0028] For example, as shown in FIG3, the elastic positioning seat 11 includes: a second upper connecting part 1104, a second lower connecting part 1105, and a second side connecting part 1106. The second upper connecting part 1104 is connected to the upper elastic member 16 and fixedly connected to the mounting surface of the floating plate assembly 30. The second lower connecting part 1105 is connected to the lower elastic member 15. The second side connecting part 1106 is used to connect the second upper connecting part 1104 and the second lower connecting part 1105. Meanwhile, the floating plate assembly 20 has a first clearance hole 201. The second side connecting part 1106 passes through the first clearance hole 201. In the direction perpendicular to the thickness of the floating plate assembly 30 (lateral direction), the second side connecting part 1106 is spaced from the inner wall of the first clearance hole 201. It can be understood that by opening a clearance hole on the power plate assembly 20 to avoid the second side connecting part 1106, the elastic connecting seat 11 can move relative to the power plate assembly 20 in the lateral direction.

[0029] Optionally, the mounting ends of the two elastic elements can be directly fixedly connected to the power plate assembly 20, or a power end mounting seat can be set in the adaptive elastic component. The power end mounting seat is connected to the two elastic elements respectively, and then fixedly connected to the power plate assembly 20 through the power end mounting seat to facilitate installation.

[0030] In some embodiments, as shown in FIG4, the floating docking mechanism further includes: a first positioning boss 14 and a second positioning boss 13. The first positioning boss 14 is fixedly connected to the elastic positioning seat 11, and the upper elastic member 16 is sleeved on the outside of the first positioning boss 14; the second positioning boss 13 is fixedly connected to the elastic positioning seat 11 and located below the first positioning boss 14, and the lower elastic member 15 is sleeved on the outside of the second positioning boss 13. It can be understood that the two positioning bosses are respectively fixed above and below the elastic positioning seat 11, and the two elastic members are respectively sleeved on the outside of the two positioning bosses and in contact with the two positioning bosses, reducing the risk of the elastic members moving out laterally during deformation. This sleeved limiting method also eliminates the need to fix the end of the elastic member to the elastic positioning seat 11, reducing the installation difficulty of the elastic member. Optionally, in the lateral direction, there is a certain gap between the outer edge of the positioning boss and the inner edge of the elastic member, the gap being between 5 mm and 8 mm, that is, the positioning boss and the elastic member form a gap fit to reduce the installation difficulty of the elastic member.

[0031] In some embodiments, the floating docking mechanism further includes a positioning post 1301, the two ends of which are fixedly connected to the first positioning boss 14 and the second positioning boss 13, respectively, to fix the two positioning bosses into a whole. Meanwhile, the adaptive elastic component 10 also includes a power end mounting seat 12, which is fixedly connected to the first mounting end of the upper elastic member 16 and the second mounting end of the lower elastic member 15. The power end mounting seat 12 is also fixedly connected to the power plate assembly 20. It can be understood that the two elastic members are fixedly connected to the power plate assembly 20 via the power mounting seat 12. This facilitates the installation of the adaptive elastic component 10 and the power plate component 20. Meanwhile, the power end mounting base 12 has a second clearance hole 1201, and the positioning post 1301 is located inside the second clearance hole 1201. That is, in addition to connecting the two positioning bosses into one to improve the overall structural stability of the two positioning bosses, the positioning post 1301 can also limit the maximum lateral movement distance of the power plate component 20 by the distance between the outer edge of the positioning post 1301 and the inner edge of the second clearance hole 1201, so as to reduce the risk of lateral instability of the adaptive elastic component 10 caused by excessive lateral deformation of the power plate component 20.

[0032] Optionally, as shown in Figure 4, the first positioning boss 14, the second positioning boss 13, the upper elastic member 16, and the lower elastic member 15 can form an integral structure; optionally, the first positioning boss 14, the second positioning boss 13, the positioning post 1301, the upper elastic member 16, and the lower elastic member 15 can form a detachable structure. For example, the second positioning boss 13 and the positioning post 1301 form an integral structure, and the second positioning boss 13 is fixed to the lower end face of the elastic positioning seat 11 by a lower fastening screw 1802. The first positioning boss 14... The upper positioning boss 14 is fixed to the upper end face of the elastic positioning seat 11 by the fastening screw 1803, and the first positioning boss 14 is fixedly connected to the positioning post 1301 by the positioning seat fastening screw 1801. The upper elastic member 16 is sleeved on the outside of the first positioning boss 14, and the upper and lower end faces of the upper elastic member 16 elastically abut against the first positioning boss 14 and the power end mounting seat 12 respectively. The lower elastic member 15 is sleeved on the outside of the second positioning boss 13, and the upper and lower end faces of the lower elastic member 15 elastically abut against the power end mounting seat 12 and the second positioning boss 13 respectively.

[0033] In some embodiments, as shown in FIG4, the floating docking mechanism further includes a buffer anti-collision sleeve 17, which is sleeved on the outside of the positioning post 1301, thereby avoiding the risk of the upper elastic member 16 and the lower elastic member 15 colliding with the positioning post 1301 under large lateral deformation; optionally, the buffer anti-collision sleeve 17 is made of EPDM rubber, and the gap between the outer diameter of the buffer anti-collision sleeve 17 and the inner diameter of the elastic member is between 5 mm and 8 mm.

[0034] In some embodiments, as shown in FIG1, each adaptive elastic component 10 is centrally symmetrically distributed with respect to the floating plate assembly 30. By having multiple adaptive elastic components 10 bear the load transmitted by the floating plate assembly 30, the risk of local overload of a single adaptive elastic component 10 is reduced. Moreover, by centrally symmetrically arranging each adaptive elastic component 10, the load of the floating plate assembly 30 is transmitted to each adaptive elastic component 10 as evenly as possible, further reducing the risk of local overload of a single adaptive elastic component 10.

[0035] In some embodiments, as shown in FIG5, the power plate assembly 20 includes a floating end connection portion 21 and a drive source connection portion 22. The floating end connection portion 21 is fixedly connected to the upper elastic member 16 and the lower elastic member 15. The drive source connection portion 22 is fixedly connected to the floating end connection portion 21 and is used to connect to a drive source. An external drive source can drive the floating end connection portion 21 to move axially through the drive source connection portion 22. It can be understood that during the docking process, the power plate assembly 20 is moved upward by the external drive source, thereby driving the floating plate assembly 30 to approach the external heavy-duty equipment, thereby realizing the docking of the floating docking mechanism. The external drive source can be a motor, a hydraulic or pneumatic drive device, or a manually driven structure.

[0036] In some embodiments, as shown in FIG1, the floating plate assembly 30 includes a floating plate 31 and guide pins 32. The mounting surface of the floating plate 31 is connected to the adaptive elastic component 10. The mating surface of the floating plate 31 has a plurality of guide pins 32, and each guide pin is symmetrically distributed along the geometric center of the floating plate 31, thereby facilitating docking with external heavy-duty equipment. Optionally, the floating plate 31 is provided with a plurality of standardized fixed mounting interfaces 3101 for connector plugs, for connecting with connector plugs to achieve docking and adaptation with external equipment connector sockets.

[0037] In some embodiments, as shown in FIG1, the end of the guide pin 32 extending out of the mating surface forms a guide surface. Along the direction in which the guide pin 32 extends out of the mating surface, the cross-sectional area of ​​the portion of the guide pin with the guide surface decreases. That is, an inclined surface is formed by the guide surface. During the mating process, if the guide pin 32 is not strictly aligned with the mating hole of the external heavy-duty equipment, the lateral component of the guide surface of the guide pin 32 can enable the guide pin 32 to automatically align with the mating hole and insert into the mating hole.

[0038] Optionally, mechanical, electrical, or mechanical plus electrical dual-insurance technology can be adopted. Tension and pressure sensors can be installed on the floating plate 31 in Figure 1 to feed back the mechanical signal to the control box during the docking process to stop the machine in time and avoid damage to the docking equipment. Alternatively, the stroke of the electric cylinder can be fixed within a certain range by adjusting the adjusting nut at the front end of the electric cylinder during assembly to prevent the floating docking mechanism from over-travel and overload.

[0039] Optionally, the upper elastic element 16 and the lower elastic element 15 are made of spring steel 55CrSi (55 chromium silicon, spring steel), which is blackened and then painted to meet the requirements of marine environments.

[0040] 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.
