Description

Technical Field

[0001] The invention relates to the field of energy absorbing and shock absorbing mechanisms, and in particular to a mechanism capable of absorbing instantaneous shock waves or energy. Background Art

[0002] Usually, in order to improve the comfort of passengers, seats on vehicles are equipped with energy-absorbing and shock-absorbing devices to absorb the vibration caused by vehicle bumps caused by road conditions during driving. The shock-absorbing performance of the seats directly determines the comfort of riding. The anti-seismic design of the seats not only has the effect of shock absorption, but also has an important effect on lightning protection in the military field, which directly affects the combat effectiveness of combatants.

[0003] The shock-absorbing mechanism of traditional seats can only cope with normal vibrations. For vibrations with relatively large instantaneous impact forces such as landmine explosions, traditional shock-absorbing mechanisms cannot quickly and effectively complete energy absorption and shock reduction. At this time, a mechanism is needed that can absorb a large amount of impact energy in an instant. With the help of this mechanism, the huge vibrations caused by the instantaneous energy impact can be effectively resolved. Summary of the invention

[0004] In view of the above problems, the present invention is proposed to provide an energy absorbing and shock absorbing mechanism that overcomes the above problems or at least partially solves the above problems.

[0005] According to one aspect of the present invention, an energy absorbing and shock absorbing mechanism is provided, characterized in that the energy absorbing and shock absorbing mechanism comprises an upper connecting rod, an upper fixed end, an unlocking rod, a lower fixed end, an energy absorbing shell, a locking bolt, and a lower connecting rod.

[0006] Preferably, the upper fixed end is a cylindrical structure, a plurality of threaded holes are arranged on the upper fixed end, a through hole is arranged on the upper fixed end along the horizontal direction, a threaded adjustment hole is arranged on the bottom of the upper fixed end, and the upper fixed end and the lower fixed end have the same structure.

[0007] Preferably, the unlocking rod is a cylindrical structure, and threads are set at both ends of the unlocking rod to be rotatably connected with the adjustment hole of the upper fixed end and the adjustment hole of the lower fixed end. The unlocking rod is provided with an unlocking area, and the diameter of the unlocking area is smaller than the diameter of the unlocking rod.

[0008] Preferably, the upper connecting rod passes through the upper fixed end through hole, and the lower connecting rod passes through the lower fixed end through hole.

[0009] Preferably, the energy absorbing shell is composed of two semi-threaded telescopic structures spliced ​​together, the energy absorbing shell is made of elastic metal material, and the energy absorbing shell is provided with a plurality of through holes.

[0010] Preferably, the energy absorbing shell is fixedly connected to the threaded hole of the upper fixed end by means of the locking bolt, and the energy absorbing shell is fixedly connected to the threaded hole of the lower fixed end by means of the locking bolt.

[0011] Preferably, the energy absorbing and shock absorbing mechanism has two working states, namely an initial state and a protection state;

[0012] When the external force applied to the upper connecting rod is always less than the critical value, the energy absorbing and shock absorbing mechanism maintains the initial state, and the upper connecting rod and the lower connecting rod move upward synchronously;

[0013] When the external force applied to the upper connecting rod suddenly exceeds the critical value, the energy absorbing and shock absorbing mechanism enters a protection state, the upper connecting rod moves along the direction of the external force, the unlocking rod is broken along the unlocking area by the force, the energy absorbing shell is straightened by the force to absorb energy, and the lower connecting rod slowly moves upward.

[0014] Preferably, the critical value is equal to the minimum external force that the unlocking area of ​​the unlocking rod is subjected to when it breaks.

[0015] The beneficial effects of the present invention are as follows: compared with other shock absorbing mechanisms, the use of this energy absorbing shock absorbing mechanism can effectively solve the huge vibration caused by shock waves such as explosions. At the same time, the simplified design not only improves production efficiency, but also ensures the equipment's efficient response capability when facing external shocks or vibrations, thereby enhancing the safety and reliability of the system; by reducing unnecessary parts, this mechanism not only reduces the cost of manufacturing and maintenance, but also reduces potential failure points and extends the service life of the equipment.

[0040] Embodiment 1:

[0041] According to one aspect of the present invention, an energy absorbing and shock absorbing mechanism 1 is designed. Figure 1 FIG. 4 shows a stereoscopic diagram of an energy absorbing and shock absorbing mechanism according to an embodiment of the present invention. Figure 1 As shown, the energy absorbing and shock absorbing 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] It can be seen that compared with the existing energy-absorbing and shock-absorbing mechanisms, this energy-absorbing and shock-absorbing mechanism requires fewer parts, which is convenient for early assembly and later maintenance and repair work. Similarly, fewer parts mean that the required mold opening costs will also be greatly reduced, which can further save development and subsequent production costs.

[0043] In some embodiments of the present invention, Figure 3 FIG. 4 shows a perspective view of an upper fixing end according to an embodiment of the present invention. Figure 3 As shown, the upper fixed end 3 is a cylindrical structure, and a plurality of threaded holes 9 are arranged on the upper fixed end 3, which can facilitate the subsequent fixation of the energy-absorbing shell 6; a through hole 10 is arranged on the upper fixed end 3 in the horizontal direction, and a threaded adjustment hole 11 is arranged on the bottom of the upper fixed end 3, which can be used to fix the position of the unlocking rod 4, and the upper fixed end 3 and the lower fixed end 5 have the same structure.

[0044] It can be seen that the upper fixed end and the lower fixed end of the energy absorbing and shock absorbing mechanism are universal parts, which do not require additional design costs and mold opening costs. This design is also convenient for production and assembly, including subsequent maintenance, which only requires one part to replace two parts at the same time.

[0045] In some embodiments of the present invention, Figure 4FIG. 2 shows a perspective view of an unlocking lever according to an embodiment of the present invention. Figure 4 As shown, the unlocking rod 4 is a cylindrical structure, and threads are set at both ends of the unlocking rod 4 for rotationally connecting with the adjustment holes 11 set at the upper fixed end 3 and the lower fixed end 5. The length of the threads at both ends of the unlocking rod 4 is not limited, and the length of the unlocking rod 4 entering the upper fixed end 3 and the lower fixed end 5 can be adjusted arbitrarily according to actual needs. The unlocking rod 4 is provided with an unlocking area 4-1, and the diameter of the unlocking area 4-1 is smaller than the diameter of the unlocking rod 4.

[0046] It can be seen that the connection method between the unlocking 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. At the same time, this adjustment method can also effectively solve the assembly mismatch problem caused by the production size error of the unlocking rod or the energy absorbing shell.

[0047] In some embodiments of the present invention, Figure 2 FIG. 4 shows a cross-sectional view of an energy absorbing and shock absorbing mechanism according to an embodiment of the present invention. 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 and shock absorbing mechanism 1 .

[0049] In some embodiments of the present invention, Figure 5 FIG. 4 shows a comparison diagram of two states of the energy absorbing shell according to an embodiment of the present invention. Figure 5 As shown, the energy absorbing shell 6 is composed of two semi-threaded telescopic structures spliced ​​together. The energy absorbing shell 6 is made of elastic metal material. The energy absorbing shell 6 is a material with good elasticity. Its energy absorption strength can be selected according to actual needs by selecting appropriate materials and the number of compressed rings. The energy absorbing shell 6 is provided with multiple through holes 10.

[0050] It can be seen that the energy absorbing shell is the main energy absorbing device of the energy absorbing and shock absorbing mechanism, and its energy absorbing strength directly determines the shock absorbing effect of the energy absorbing and shock absorbing mechanism.

[0051] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the energy absorbing shell 6 is fixedly connected to the threaded hole 9 of the upper fixed end 3 through the locking bolt 7, and the energy absorbing shell 6 is fixedly connected to the threaded hole 9 of the lower fixed end 5 through the locking bolt 7.

[0052] It can be seen that the energy-absorbing shell is removable. This design method is helpful for later inspection and maintenance, saving maintenance costs, and at the same time can ensure that the energy-absorbing and shock-absorbing mechanism is always in normal working condition to the greatest extent.

[0053] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the energy absorbing and shock absorbing mechanism 1 has two working states, namely, an initial state and a protection state;

[0054] Specifically, when the external force on the upper connecting rod 2 is always less than the critical value, the energy absorbing and shock absorbing mechanism 1 maintains the initial state, and the upper connecting rod and the lower connecting rod 8 move upward synchronously;

[0055] Specifically, when the external force applied to the upper connecting rod 2 is suddenly greater than a critical value, the energy absorption and shock absorbing mechanism 1 enters a 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 by the force, the energy absorbing shell 6 is straightened by the force to absorb energy, and the lower connecting rod 8 slowly moves upward.

[0056] It can be seen that the energy-absorbing and shock-absorbing mechanism can absorb the impact of external instantaneous energy on the device where the energy-absorbing and shock-absorbing mechanism is located to the greatest extent, and weaken the damage of this impact to the device.

[0057] In some embodiments of the present invention, Figure 4 As shown, the critical value is equal to the minimum external force that the unlocking area 4-1 of the unlocking rod 4 is subjected to when it breaks.

[0058] It can be seen that the setting of the unlocking area not only ensures that the unlocking rod will not break easily under normal circumstances and always maintain a normal working state, but also ensures that the energy absorption unlocking mechanism can immediately break and trigger the energy absorption protection mechanism when encountering a strong impact force.

[0059] In summary, compared with other shock-absorbing mechanisms, the use of this energy-absorbing shock-absorbing mechanism can effectively solve the huge vibration caused by shock waves such as explosions. At the same time, the simplified design not only improves production efficiency, but also ensures the equipment's efficient response capabilities when facing external shocks or vibrations, thereby enhancing the safety and reliability of the system; by reducing unnecessary parts, this mechanism not only reduces manufacturing and maintenance costs, but also reduces potential failure points and extends the service life of the equipment.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
