Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical damping and buffering, in particular to a damping docking structure. BACKGROUND

[0002] At present, docking of large mechanical structures, such as docking of aircraft in the field of aerospace and docking between high-speed train carriages in the field of rail transit, requires the use of docking structures. However, the current docking structures cannot meet the requirements of high impact energy absorption and high static stiffness, resulting in excessive impact load during docking collision, which can easily cause damage to the large mechanical structure and the docking structure itself. SUMMARY

[0003] In order to overcome the above problems, the present application provides a damping docking structure, which solves the technical problems thereof by adopting the technical scheme that:

[0004] A damping docking structure, comprising a first docking member and a second docking member located on the same axis, the first docking member comprising a first base, the first base being provided with a first docking barrel, the front end of the first docking barrel being provided with a buffering energy absorption disc, the buffering energy absorption disc being provided with a first docking hole and a displacement block, the first base being provided with a first electromagnet assembly, the first docking barrel being provided with a fixed guide plate and a sliding magnetic plate, the fixed guide plate being provided with a guide hole and a range finder, the sliding magnetic plate being fixedly provided with a center connecting rod facing the fixed guide plate, the center connecting rod being slidably arranged through the guide hole, the first docking barrel being provided with a first elastic member between the fixed guide plate and the sliding magnetic plate, the first elastic member having a tendency to drive the sliding magnetic plate to slide away from the fixed guide plate; the second docking member comprising a second base, the second base being provided with a second docking barrel, the front end of the second docking barrel being provided with a convex cone head, the convex cone head being provided with a second docking hole, the second docking barrel being provided with a fixed baffle and a locking assembly, the fixed baffle and the locking assembly being provided with a second elastic member, the second elastic member having a tendency to drive the locking assembly to slide into the convex cone head; the first docking member and the second docking member are close to each other, the convex cone head is pressed against the buffering energy absorption disc, the buffering energy absorption disc is elastically deformed backward and drives the displacement block to move, the range finder detects that the displacement block moves to a specified position, the first electromagnet assembly is powered on to drive the sliding magnetic plate to slide close to the fixed guide plate, and the center connecting rod is docked and locked with the locking assembly after passing through the first docking hole and the second docking hole.

[0005] Further, the buffering energy absorption disc comprises a plurality of coaxially nested circular rings connected in a spiral curved beam, the front end of the circular ring is larger in diameter than the rear end to form a telescopic sleeve structure; when the convex cone head is pressed against the buffering energy absorption disc, the inner circular ring is first stressed and moves backward to drive the adjacent outer circular ring to move backward, and each adjacent two circular rings are progressively moved backward to buffer the convex cone head.

[0006] Further, the first docking hole is the inner circle of the innermost circular ring, and the displacement block is fixedly connected with the innermost circular ring.

[0007] Furthermore, the locking assembly includes a locking cylinder. The front end of the locking cylinder is a conical inner cylinder with the same taper as the convex cone head. A third docking hole is provided at the front end of the conical inner cylinder. Several limiting windows are symmetrically arranged on the conical surface of the conical inner cylinder. Several locking balls are arranged inside the conical inner cylinder. The locking balls fall into the limiting windows one by one, and the diameter of the locking balls is greater than the maximum width of the limiting windows. A limiting plate is provided inside the locking cylinder. The limiting plate ensures that the locking balls move back and forth together in the same plane to retract into / partially extend out of the limiting windows. A gap is formed between the locking balls. The gap increases / decreases as the locking balls move back and forth to dock with the locking center connecting rod.

[0008] Furthermore, a fourth mating hole is provided on the limiting plate, and a second elastic element is provided between the fixed baffle and the limiting plate; a locking groove is provided on the central connecting rod. The central connecting rod passes through the first mating hole and the second mating hole, and then passes through the third mating hole into the locking assembly, driving the locking assembly to compress the second elastic element and move backward. The limiting plate restricts the locking balls to move backward simultaneously in the same plane, and the gap between the locking balls becomes larger. The central connecting rod passes through the gap and enters the fourth mating hole. The locking balls roll forward along the surface of the central connecting rod until they fall into the locking groove to mate with and lock the central connecting rod.

[0009] Furthermore, a second electromagnet assembly is provided inside the second base. When the second electromagnet assembly is powered on, it drives the locking assembly to compress the second elastic element and move it backward. The locking ball moves backward and disengages from the locking groove. The first elastic element drives the sliding magnetic plate to slide backward away from the fixed guide plate. The central connecting rod slides backward through the fourth docking hole, the third docking hole, and the second docking hole, and then retracts the first docking member through the first docking hole.

[0010] Furthermore, the first electromagnet assembly, the second electromagnet assembly, and the rangefinder are all electrically connected to the central controller.

[0011] Furthermore, it also includes a first docking seat and a second docking seat located on the same axis. The first docking seat is provided with a plurality of first docking parts, and the second docking seat is provided with a plurality of second docking parts, with the first docking parts and the second docking parts corresponding one to one.

[0012] The beneficial effects of this invention are:

[0013] The vibration-damping docking structure includes a first docking component and a second docking component located on the same axis, which are respectively installed on the two mechanical structures that need to be docked. During docking, the first and second docking components approach each other, and the convex cone head presses against the buffer energy-absorbing disk. The buffer energy-absorbing disk undergoes elastic deformation backward and drives the displacement block to move. The rangefinder detects that the displacement block has moved to the designated position. The first electromagnet assembly is energized to drive the sliding magnetic plate to slide closer to the fixed guide plate. The central connecting rod passes through the first docking hole and the second docking hole and docks and locks with the locking assembly. During docking, the buffer energy-absorbing disk can effectively absorb impact energy. The central connecting rod and the locking assembly are respectively buffered by the first elastic element and the second elastic element. The method of the central connecting rod passing through the first docking hole and the second docking hole and docking and locking with the locking assembly can play an effective vibration-damping role during locking. Through the cooperation of the buffer energy-absorbing disk, the first elastic element, and the second elastic element, vibration-damping and energy absorption can be effectively achieved during the docking and locking process of large machinery, protecting the mechanical structure and the docking structure.

[0030] To better understand the purpose, structure, and function of this invention, the following detailed description of a specific embodiment of the "Vibration Reduction Connecting Structure" of this invention is provided in conjunction with the accompanying drawings.

[0031] See Figures 1-6 In this embodiment, the vibration damping docking structure includes a first docking member 100 and a second docking member 200 located on the same axis.

[0032] The first docking component 100 includes a first base 101, on which a first docking cylinder 102 is coaxially fixed. A buffer energy-absorbing disk 103 is fixedly disposed at the front end of the first docking cylinder 102. The buffer energy-absorbing disk 103 is provided with a first docking hole 104 and a displacement block 105. A first electromagnet assembly 106 is disposed inside the first base 101. A fixed guide plate 107 and a sliding magnetic plate 108 are disposed inside the first docking cylinder 102. The fixed guide plate 107 is fixedly disposed at a position away from the first electromagnet assembly 106, and the sliding magnetic plate 108 is slidably disposed near the first electromagnet assembly 106. At the position of component 106, a guide hole 109 and a rangefinder 110 are provided on the fixed guide plate 107. The rangefinder is used to detect the position of the displacement block 105. A central connecting rod 111 is fixedly provided on the sliding magnetic plate 108 facing the fixed guide plate 107. The central connecting rod 111 can slide through the guide hole 109 and slide back and forth with the sliding magnetic plate 108. A first elastic element 112 is provided between the fixed guide plate 107 and the sliding magnetic plate 108. The first elastic element 112 is preferably a spring. The first elastic element 112 has the tendency to drive the sliding magnetic plate 108 to slide away from the fixed guide plate 107.

[0033] The second docking member 200 includes a second base 201, on which a second docking cylinder 202 is coaxially fixed. A convex cone head 203 is fixedly disposed at the front end of the second docking cylinder 202. A second docking hole 204 is disposed on the convex cone head 203. A fixed baffle 205 and a locking component 206 are disposed inside the second docking cylinder 202. The fixed baffle is fixed at a position away from the convex cone head 203. The locking component 206 is slidably disposed at a position close to the convex cone head 203. A second elastic element 207 is disposed between the fixed baffle 205 and the locking component 206. The second elastic element 207 is preferably a spring. The second elastic element 207 has a tendency to drive the locking component 206 to slide into the convex cone head 203. The central connecting rod 111, the first docking hole 104 and the second docking hole 204 are located on the same axis.

[0034] Specifically, when the first docking member 100 and the second docking member 200 approach each other for docking, the convex cone head 203 first presses against the buffer energy-absorbing disk 103. After being pressed, the buffer energy-absorbing disk 103 undergoes elastic deformation backward and drives the displacement block 105 to move backward. After the rangefinder 110 detects that the displacement block 105 has moved to the designated position, it sends a signal to the central controller. The central controller controls the first electromagnet assembly 106 to be powered on. After being powered on, the first electromagnet assembly 106 has the same magnetism as the sliding magnetic plate 108, which drives the sliding magnetic plate 108 to slide forward and compress the first elastic member 112 and approach the fixed guide plate 107. At the same time, it drives the central connecting rod 111 to slide forward through the first docking hole 104 and the second docking hole 204 and enter the first docking member 100, and dock and lock with the locking component 206 inside the first docking member 100.

[0035] It should be noted that when the central connecting rod 111 enters the first docking member 100 and docks with the locking component 206, it first presses against the locking component 206. After being subjected to force, the locking component 206 will compress the second elastic element 207 and slide backward a certain distance, providing a buffer for the locking component 206. When the elastic potential energy is large enough, the central connecting rod 111 then enters the locking component 206 to lock. Furthermore, the buffer energy-absorbing disk 103 of the present invention can provide a buffer when the first docking member 100 and the second docking member 200 dock, effectively absorbing impact energy. At the same time, in conjunction with the buffering and vibration reduction effect of the first elastic element 112 and the second elastic element 207 during locking, it can effectively play a buffering and vibration reduction role in the docking and locking process of large mechanical structures, taking into account the requirements of high impact energy absorption and high static stiffness, and protecting the large mechanical structure and docking structure.

[0036] See further Figure 3 , Figure 5 and Figure 7 In this embodiment, the buffer energy-absorbing disk 103 includes several coaxially nested rings 1031 connected in a helical curved beam configuration. The front diameter of each ring 1031 is larger than its rear diameter, and all rings 1031 form a telescopic sleeve structure. When the convex cone 203 presses against the buffer energy-absorbing disk 103, the inner ring 1031 is first subjected to force and moves backward, causing the adjacent outer ring 1031 to move backward. Each pair of adjacent rings 1031 moves backward progressively to buffer the convex cone 203, effectively achieving a buffering and energy-absorbing effect, reducing the impact force when the first docking member 100 and the second docking member dock. After docking, the concave, telescopic sleeve-shaped buffer energy-absorbing disk 103 provides effective rigid support and also achieves a vibration reduction effect. See details. Figure 12 The mechanical analysis diagram, Figure 12 The left and middle figures show the structural model of the buffer energy-absorbing disk 103, which consists of an inclined curved beam (whose central axis satisfies the Archimedes' spiral equation) connecting a central through-hole ring 1031 and an outermost ring 1031 to form a whole; when Figure 12 When the external load in the middle diagram is applied to the ring 1031, the inclined curved beam will generate contact shear interlock, thereby changing the stiffness of the overall structure. Figure 12 The figure on the right shows the static pressure finite element simulation load-displacement curve of a general macroscopic size and material buffer energy-absorbing disk 103 under the aforementioned structural model.

[0037] Specifically, see Table 1 and Table 2 below:

[0038] Table 1:

[0039]

[0040] Table 2

[0041]

[0042] Within the 0-100 mm displacement range (dynamic impact state in Table 1), the buffer energy-absorbing disk 103 exhibits a stiffness gradient evolution characteristic. In the 0-50 mm displacement range, it maintains a low stiffness of 1.2 N / mm, achieving initial energy dissipation. In the 50-100 mm displacement range, the stiffness jumps to 7.8 N / mm, forming the core energy-absorbing platform. This range absorbs a total of 14.23 J of energy (dynamic impact state in Table 2), accounting for 75% of the total energy absorbed. Of this, 90% of the energy (12.75 J) is concentrated in the 50-100 mm displacement range, with an equivalent dynamic stiffness only 17% of that in the static locking state. This gradually increasing stiffness characteristic (1.2→7.8 N / mm) enables the mechanism to efficiently reduce the force peak during dynamic impact. When the displacement >100 mm and enters the locked state (static locking state in Table 1), the stiffness increases sharply to 46.0 N / mm, forming a micro-deformation suppression barrier. It absorbs 4.74 J of energy within the 7.58 mm residual deformation space (static locking state in Table 2). Although this stage contributes only 25% of the total energy absorption, its core value lies in establishing a high-rigidity barrier: the load density reaches 46 N / mm, and the theoretical resistance to perturbations is 0.22 mm / 10 N, providing sub-millimeter-level positional stability for the docking body. In the dynamic impact state, a flexible energy dissipation channel is constructed with gradually increasing stiffness across the entire domain (1.2→7.8 N / mm) and a 75% energy absorption ratio (14.23 J). In the static locking state, a rigid locking fortress is established with ultra-high stiffness of 46.0 N / mm and a deformation-resistant stroke of 7.58 mm. The two modes switch through a 100 mm displacement critical point, ultimately achieving a performance balance between a total energy absorption capacity of 18.97 J and a locking stiffness of 46 kN / m, meeting the cross-condition requirements of large instruments such as spacecraft docking mechanisms for "collision soft landing" and "on-orbit hard locking."

[0043] More specifically, in this embodiment, the first docking hole 104 is the inner ring of the innermost ring 1031. The displacement block 105 is fixedly connected to the innermost ring 1031. After the buffer energy-absorbing disk 103 is pressed by the convex cone head 203, the innermost ring 1031 is the first to be concave inward. The fixed connection between the displacement block 105 and the innermost ring 1031 can quickly provide feedback on the deformation of the buffer energy-absorbing disk 103 so as to provide feedback to the rangefinder 110.

[0044] See further Figure 4 , Figure 6 , Figure 8 and Figure 9In this embodiment, the locking assembly 206 includes a locking cylinder 2061. The front end of the locking cylinder 2061 is a conical inner cylinder 2062 with the same taper as the convex cone head 203. The front end of the conical inner cylinder 2062 is provided with a third docking hole 2063. The third docking hole 2063, the central connecting rod 111, the first docking hole 104, and the second docking hole 204 are located on the same axis. A plurality of limiting windows 2064 are symmetrically arranged on the conical surface of the conical inner cylinder 2062. A plurality of locking balls 2065 are provided inside the conical inner cylinder 2062. The locking balls 2065 fall into the limiting windows 2064 one by one. The diameter of 65 is greater than the maximum width of the limiting window 2064 to prevent the locking ball 2065 from escaping from the limiting window 2064. A limiting plate 2066 is provided inside the locking cylinder 2061. The limiting plate 2066 can slide along the inner wall of the locking cylinder 2061. The limiting plate 2066 ensures that all locking balls 2065 move back and forth together in the same plane to retract / partially extend from the limiting window 2064. A gap is formed between the locking balls 2065. The gap increases / decreases as the locking balls 2065 move back and forth. The locking assembly 206 is locked to the central connecting rod 111 by opening and closing through the gap between the locking balls 2065.

[0045] More specifically, in this embodiment, the limiting plate 2066 is provided with a fourth docking hole 2067. The fourth docking hole 2067, the third docking hole 2063, the central connecting rod 111, the first docking hole 104, and the second docking hole 204 are located on the same axis. The second elastic element 207 is disposed between the fixed baffle 205 and the limiting plate 2066. The central connecting rod 111 is provided with a locking groove 113. The central connecting rod 111 passes through the first docking hole 104 and the second docking hole 204, and then passes through the third docking hole 2063 into the locking assembly 206. Since the gap is small at this time, the front end of the central connecting rod 111 cannot pass through the gap. The front end of the central connecting rod 111 abuts against the locking ball 2065 and drives the lock. The fixed component 206 compresses the second elastic element 207 to move backward, and the limiting plate 2066 restricts the locking balls 2065 to move backward simultaneously in the same plane. The gap between the locking balls 2065 increases. When the gap is larger than the diameter of the central connecting rod 111, the central connecting rod 111 passes through the gap and enters the fourth docking hole 2067. At this time, the resistance force of the front end of the central connecting rod 111 against the locking balls 2065 disappears. The second elastic element 207 drives the locking component 206 to move forward and enter the convex cone head 203. The locking balls 2065 roll forward along the surface of the central connecting rod 111 and the gap continues to decrease until they fall into the locking groove 113, stop relative movement, and complete docking and locking with the central connecting rod 111.

[0046] See further Figure 5 and Figure 6In this embodiment, a second electromagnet assembly 208 is provided in the second base 201. When it is necessary to release the docking lock, the second electromagnet assembly 208 is energized. After being energized, the second electromagnet assembly 208 generates a magnetic attraction force, which drives the locking assembly 206 to compress the second elastic member 207 and move it backward. The gap between the locking balls 2065 increases, and the locking balls 2065 move backward to disengage from the locking groove 113 to release the lock. Then, the first electromagnet assembly 106 is de-energized, the repulsive force on the sliding magnetic plate 108 disappears, and the first elastic member 112 drives the sliding magnetic plate 108 to slide backward away from the fixed guide plate 107. This causes the central connecting rod 111 to slide backward and pass through the fourth docking hole 2067, the third docking hole 2063, and the second docking hole 204 in sequence, and then retract the first docking member 100 through the first docking hole 104. The first docking member 100 and the second docking member 200 separate, the buffer energy-absorbing disk 103 returns to its original state, and the docking is released.

[0047] It should be noted that in this embodiment, the first electromagnet assembly 106, the second electromagnet assembly 208, and the rangefinder 110 are all electrically connected to the central controller to enable automated linkage operation and facilitate electronic control; and the sliding magnetic plate 108, the displacement block 105, the locking assembly 206, and the limiting plate 2066 all achieve smooth forward and backward sliding through existing sliding structures such as slide rails or rollers.

[0048] See further Figure 10 and Figure 11 In this embodiment, the vibration damping docking structure also includes a first docking seat 114 and a second docking seat 209 located on the same axis. The first docking seat 114 is provided with a plurality of first docking parts 100, and the second docking seat 209 is provided with a plurality of second docking parts 200. The first docking parts 100 and the second docking parts 200 correspond one-to-one. Preferably, three of each of the first docking parts 100 and the second docking parts 200 are selected and arranged in a triangular distribution, so that the first docking seat 114 and the second docking seat 209 are more stable after docking.
