[0018] Compared with the prior art, the present invention provides an anti-collision energy absorption device for a microwave denial system vehicle, which has the following beneficial effects:

[0019] 1. In the technical solution proposed by the present invention, energy absorption is achieved through a combination of a first-order energy absorber and a second-order energy absorber. The first-order energy absorber absorbs the initial energy after the impact and has a retraction space. Then, after the second-order energy absorber synchronizes the energy of the first-order energy absorber, the configuration structure of the first-order energy absorber continues to absorb energy, thereby transferring the energy to the rear end of the second-order energy absorber. After the first-order energy absorber absorbs energy to a maximum threshold, the second-order energy absorber performs its own structural counteraction energy absorption. Thus, secondary energy absorption is performed based on a limited extension length, thereby solving the problem of a short energy absorption stroke and low energy absorption.

Through the multi-level setting, in a specific scenario, when the microwave denial vehicle equipped with the energy-absorbing component is impacted, the hierarchical reinforcement ring and the aluminum honeycomb energy-absorbing layer are set to buffer the impact force, thereby meeting the protection of the human body.

[0021] 3. A buffer pusher is provided, wherein the buffer pusher includes a connecting pipe, and a connecting sleeve is connected to the outer surface of the connecting pipe, wherein the connecting sleeve is connected to the annular surface of the connecting pipe with a conical slow-slip sleeve, wherein the connecting pipe is circumferentially arranged with the center of the outer ring cover as the origin, and the opposite end face of the end connected to the outer ring cover is installed on the end face of the conical top piece, and then after being subjected to a specific impact force, after the body is deformed, the buffering is satisfied by the subsequent change in its distance and the subsequent cooperation with the buffer pusher's own setting.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figure 1-5 As shown, an anti-collision energy absorption device for a vehicle of a microwave denial system includes a microwave denial vehicle 1. A first-order energy absorbing member 2 is installed at the front end of the microwave denial vehicle 1. A second-order energy absorbing member 3 for supporting the first-order energy absorbing member 2 is sleeved on the first-order energy absorbing member 2. During actual use, the first-order energy absorbing member is first used to absorb the impact force. After the first-order energy absorbing member gradually shrinks and the contact point gradually moves toward the second-order energy absorbing member, the second-order device produces resistance to the contact point. During the resistance process of the second-order energy absorbing member 3, the first-order energy absorbing member 2 connected in the second-order energy absorbing member 3 is subjected to the force and produces continuous energy absorption. After the first-order energy absorbing member 2 completes energy absorption, the second-order energy absorbing member 3 itself shatters to produce a final buffer.

[0033] The first-order energy absorbing member 2 includes a plurality of energy absorbing components 4, wherein the energy absorbing component 4 includes a detachable support platform 41 mounted on the front end of the microwave denial vehicle 1. The support platform 41 is mounted on the front end of the microwave denial vehicle 1 to maintain stability and provide support for subsequent energy absorption. A hierarchical reinforcement ring 42 is mounted on the support platform 41, and an aluminum honeycomb energy absorbing layer 43 is mounted on the inner ring surface of the reinforcement ring. In this specific embodiment, the aluminum honeycomb energy absorbing layer 43 is set as an integral serial honeycomb energy absorbing structure. The article "Research on the Differential Impact Performance of Honeycomb Aluminum Energy Absorbing Structure" specifically states that "after comparing the crashworthiness evaluation indicators, the results show that the absorption capacity of the integral serial honeycomb energy absorbing structure is better than that of the integral combined honeycomb energy absorbing structure." That is, in this embodiment, the setting of the aluminum honeycomb energy absorbing structure effectively enhances the energy absorption effect of the reinforcement ring. The inner ring of the aluminum honeycomb energy absorbing layer 43 is internally connected with a disassembly component 44.

[0034] The disassembly component 44 includes a positioning ring 441 that is internally connected to the aluminum honeycomb energy absorbing layer 43. The positioning ring 441 is internally connected to a conical top piece 442. A buffer pusher 443 is installed on the end face of the conical top piece 442. An outer ring cover 444 is provided on the buffer pusher 443. The structural diameter of the outer ring cover 444 is larger than the structural diameter of the buffer pusher 443. Through the setting of the outer ring cover 444, the remaining structure of the disassembly component 44 is effectively wrapped when no collision occurs, preventing the exposed structure from causing scratches to pedestrians. The positioning ring 441 includes a lining ring. The lining ring is decomposed into four levels. Threaded ring plates are installed on the four-level structure of the lining ring. The combined diameter of the threaded ring plates is smaller than the aluminum honeycomb energy absorbing layer 43, and a carbon fiber ring plate is sleeved between the aluminum honeycomb energy absorbing layer 43 and the threaded ring plate.

[0035] The second-stage energy absorbing member 3 includes two mounting seats 31 , and an energy absorbing box 32 is connected to the two mounting seats 31 . The energy absorbing box 32 is provided with an inner groove 33 .

[0036] The buffer pusher 443 includes a connecting tube 445, and a connecting sleeve is connected to the outer surface of the connecting tube 445, wherein a conical slow-slip sleeve 446 is connected to the annular surface of the connecting sleeve and the connecting tube 445, wherein the connecting tube 445 is circumferentially arranged with the center of the outer ring cover 444 as the origin, and the opposite end face of the end connected to the outer ring cover 444 is installed on the end face of the conical top piece 442. After being subjected to a specific impact force, after the main body is deformed, the buffering is satisfied by the subsequent change in its distance and the subsequent coordination with the buffer pusher 443 itself.

[0037] The energy absorption box 32 is symmetrical in the upper and lower parts, and the structure above the symmetry line of the energy absorption box 32 includes a connecting end 321 for connecting to the mounting seat 31. The connecting end 321 is connected to a support section 322 at the end away from the mounting seat 31. A plurality of supporting inner rods 323 are installed on the inner wall of the support section 322. Support rebound members 324 are installed staggered between the plurality of supporting inner rods 323. The support rebound members 324 extend toward the end away from the mounting seat 31. A return baffle 328 movably connected to the connecting end 321 is provided at the other end of the support rebound member 324.

[0038] The diameter of the relative end faces of the conical top piece 442 and the outer ring cover 444 is larger than the diameter of the end face of the outer ring cover 444, and an inner groove 33 is provided on the conical top piece 442, and an annular groove adapted to the diameter of the outer ring cover 444 is provided on the relative end faces of the conical top piece 442 and the outer ring cover 444. The diameter of the lower end face of the conical top piece 442 is equal to the combined diameter of the fourth-order liner ring, and a sliding piece is installed on the inner ring surface of the liner ring, and a sliding groove adapted to the sliding piece is provided on the conical top piece 442 structure, and a docking energy absorption guide bin is installed relative to the conical top piece 442 and the buffer pusher 443, and the energy absorption guide bin is filled with polyurethane foam.

[0039] Example 2:

[0040] like Figure 6 As shown, based on the first embodiment, two mounting bases 31 are symmetrically mounted on the microwave denial vehicle 1 in the upper and lower parts, and the two mounting bases 31 are connected with an energy absorbing box 32 which is wrapped and sleeved on the conical top piece 442. The energy absorbing box 32 is provided with an inner groove 33 which is adapted to the structure and shape of the conical top piece 442. The conical top piece 442 extends from the inner groove 33 and penetrates the energy absorbing box 32, thereby first absorbing the impact energy of the first wave. The energy absorbing box 32 is symmetrical in the upper and lower parts, and the material hardness of the energy absorbing box 32 itself is greater than the material hardness of the structure in the first-order energy absorbing piece 2. Based on the upper and lower symmetrical structural mode of the energy absorbing box 32, the structure above its symmetry line is taken as an example, and the structure above its symmetry line includes a The connecting end 321 connected to the mounting seat 31 is connected to the mounting seat 31 by bolts. The mounting seat 31 is fixed to the vehicle body. The connecting end 321 is connected to the supporting section 322 at one end away from the mounting seat 31. A plurality of supporting inner rods 323 are installed on the inner wall of the supporting section 322. The extension length of the supporting inner rods 323 on the supporting section 322 is not less than the retraction distance of the supporting platform 41, the hierarchical reinforcement ring 42 and the aluminum honeycomb energy absorbing layer 43 after energy absorption, thereby limiting the sliding distance of the return baffle 328 on the supporting section 322. Support rebound parts 324 are staggered between the plurality of supporting inner rods 323. The support rebound part 324 is composed of an inner rod 325, an outer rod 326 and a compression spring 327. When the spring 327 is pressed against the support frame 322, the spring 327 is pressed against the support frame 322, and the spring 327 is pressed against the support frame 322. When the spring 327 is pressed against the support frame 322, the spring 327 is pressed against the support frame 322, and the spring 327 is pressed against the support frame 322. After the impact energy is completely absorbed, the return baffle 328 is continuously pushed up, and the energy is synchronized to the inner rod 325. After the inner rod 325 generates a compressive force on the compression spring 327, it retracts into the inner part of the outer rod 326. As a result, the return baffle 328 slides on the support section 322 and uses the limit of the supporting inner rod 323 as the sliding end point. As a result, the first-order energy absorbing member 2 has completed the maximum energy absorption of the overall structure. If the impact energy is not completely absorbed, the return baffle 328 bears the main energy absorption until it is pushed to the maximum deformation, and then pushes the support section 322. After the support section 322 is pushed to the maximum deformation, the energy absorption of the second-order energy absorbing member 3 reaches the threshold, completing the overall energy absorption operation of the anti-collision energy absorption device.
