[0040] Embodiment one:
[0041] According to one aspect of the present application, an energy-absorbing damping mechanism 1 is designed, Figure 1 The energy-absorbing damping mechanism according to one embodiment of the present application is shown in the perspective view, as shown in Figure 1 The energy-absorbing damping mechanism 1 includes an upper connecting rod 2, an upper fixed end 3, an unlocking rod 4, a lower fixed end 5, an energy-absorbing shell 6, a locking bolt 7, and a lower connecting rod 8.
[0042] As can be seen, compared with the existing energy-absorbing damping mechanism, the energy-absorbing damping mechanism requires fewer parts, facilitating early assembly and later maintenance and repair work. Similarly, fewer parts mean that the mold opening cost required will be greatly reduced, which can further save development and subsequent production costs.
[0043] In some embodiments of the present application, Figure 3 The upper fixed end according to one embodiment of the present application is shown in the perspective view, as shown in Figure 3 The upper fixed end 3 is a cylindrical structure, and the upper fixed end 3 is provided with a plurality of threaded holes 9, which can facilitate the fixation of the subsequent energy-absorbing shell 6; the upper fixed end 3 is provided with a through hole 10 in the horizontal direction, and the bottom of the upper fixed end 3 is provided with a threaded adjusting hole 11, which can be used to fix the position of the unlocking rod 4; the upper fixed end 3 and the lower fixed end 5 are of the same structure.
[0044] As can be seen, the upper fixed end and the lower fixed end of the energy-absorbing damping mechanism are universal parts, without additional design and mold opening costs. Similarly, this design also facilitates production and assembly, including subsequent maintenance, which only requires one type of part to replace two parts.
[0045] In some embodiments of the present application,Figure 4 A locking rod is shown according to an embodiment of the utility model, as shown in Figure 4 As shown, the locking rod 4 is a cylindrical structure, the locking rod 4 both ends are provided with thread for with the upper fixed end 3 and the lower fixed end 5 setting the adjusting hole 11 rotation connection, the thread length of the locking rod 4 both ends is not limited, the length that the locking rod 4 enters the upper fixed end 3 and the lower fixed end 5 can be adjusted arbitrarily according to actual needs, the locking rod 4 sets the unlocking area 4-1, and the unlocking area 4-1 diameter is less than the locking rod 4 diameter.
[0046] It can be seen that the connection mode of the locking rod and the upper fixed end and the lower fixed end can effectively adjust the distance between the upper fixed end and the lower fixed end according to actual needs, and meanwhile, this adjustment mode can also effectively solve the assembly mismatching problem caused by the production size error of the locking rod or the energy-absorbing shell.
[0047] In some embodiments of the utility model, Figure 2 A cross-sectional view of an energy-absorbing damping mechanism is shown according to an embodiment of the utility model, as shown in Figure 1 And Figure 2 As shown, the upper connecting rod 2 passes through the through hole of the upper fixed end 3, and the lower connecting rod 8 passes through the through hole 10 of the lower fixed end 5.
[0048] It can be seen that the upper connecting rod 2 and the lower connecting rod 8 can be used to fix the energy-absorbing damping mechanism 1.
[0049] In some embodiments of the utility model, Figure 5 A comparison diagram of two states of an energy-absorbing shell is shown according to an embodiment of the utility model, as shown in Figure 5 As shown, the energy-absorbing shell 6 is composed of two half-thread telescopic structures, the energy-absorbing shell 6 is of elastic metal material, the energy-absorbing shell 6 is of good elasticity, and the energy-absorbing strength thereof can be selected according to actual needs.
[0050] It can be seen that the energy-absorbing shell is the main energy-absorbing device of the energy-absorbing damping mechanism, and the energy-absorbing strength thereof directly determines the damping effect of the energy-absorbing damping mechanism.
[0051] In some embodiments of the utility model, as Figure 1 And Figure 2 As shown, the energy-absorbing shell 6 is fixedly connected with the threaded hole 9 of the upper fixed end 3 through the locking bolt 7, and the energy-absorbing shell 6 is fixedly connected with the threaded hole 9 of the lower fixed end 5 through the locking bolt 7.
[0052] It can be seen that the energy absorption shell is detachable, the design helps late inspection and maintenance, saves maintenance cost, and can ensure that the energy absorption damping mechanism is always in normal working state.
[0053] In some embodiments of the utility model, as shown in Figure 1 and Figure 5 The energy absorption damping mechanism 1 has two working states, which are initial state and protection state respectively.
[0054] Specifically, when the external force acting on the upper connecting rod 2 is always less than the critical value, the energy absorption damping mechanism 1 maintains the initial state, and the upper connecting rod 2 and the lower connecting rod 8 move upward synchronously.
[0055] Specifically, when the external force acting on the upper connecting rod 2 is suddenly greater than the critical value, the energy absorption damping mechanism 1 enters the protection state, the upper connecting rod 2 moves along the direction of the external force, the unlocking rod 4 is broken along the unlocking area 4-1 under stress, the energy absorption shell 6 is straightened under stress to absorb energy, and the lower connecting rod 8 moves slowly upward.
[0056] It can be seen that the energy absorption damping mechanism can maximize the absorption of external instantaneous energy to the device where the energy absorption damping mechanism is located, and weaken the damage of the impact to the device.
[0057] In some embodiments of the utility model, as shown in Figure 4 The critical value is equal to the minimum external force when the unlocking area 4-1 of the unlocking rod 4 is broken.
[0058] It can be seen that the setting of the unlocking area not only ensures that the unlocking rod will not be easily broken and always maintains in the normal working state under normal circumstances, but also ensures that the energy absorption unlocking mechanism can be broken immediately to start the energy absorption protection mechanism when encountering strong impact force.
[0059] In summary, compared with other damping mechanisms, the energy absorption damping mechanism can effectively solve the huge vibration caused by the shock wave such as explosion, and the simplified design not only improves the production efficiency, but also ensures the high response ability of the equipment when facing external impact or vibration, thereby enhancing the safety and reliability of the system; by reducing unnecessary parts, the mechanism not only reduces the manufacturing and maintenance cost, but also reduces the potential failure point, prolongs the service life of the equipment.
[0060] The above is only a preferred embodiment of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model are included in the protection scope of the utility model.
