[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0042] See also Figures 1 to 4 The utility model provides a protective energy absorbing device, which is connected to a vehicle body 1, and includes: a protective component 2 and at least two connecting components 3. The protective component 2 includes a protective part 21 and two energy absorbing parts 22. The protective part 21 is arranged below the vehicle body 1.

The clamping part 32 is arranged relative to the connecting part 31 and can be clamped with the connecting part 31, so as to detachably connect the protective part 21 and the energy absorbing part 22 to the vehicle body 1.

[0043] In the present device, a protective portion 21 is provided below the vehicle body 1, two energy absorbing portions 22 are provided on both sides of the protective portion 21 and are connected to the protective portion 21, at least two connecting portions 31 are respectively connected to both sides of the vehicle body 1, and a clamping portion 32 is provided relative to the connecting portion 31 and can be clamped with the connecting portion 31, so as to detachably connect the protective portion 21 and the energy absorbing portion 22 to the vehicle.

[0044] Compared with the prior art, a protective part 21 and an energy-absorbing part 22 are provided under the vehicle body 1, and the protective part 21 and the energy-absorbing part 22 are utilized to buffer and absorb the acceleration and impact force of the vehicle at the moment of landing, thereby avoiding damage to the vehicle. At the same time, by snapping the connecting component 3 with the vehicle body 1 and the energy-absorbing part 22, a detachable connection between the protective part 21 and the energy-absorbing part 22 and the vehicle body 1 is achieved, which is convenient for users to install and disassemble, and can solve the technical problem in the prior art that the acceleration and impact force of the vehicle at the moment of landing when the vehicle is airdropped to the ground by a transport aircraft may cause damage to the vehicle.

[0045] Furthermore, in the present device, the protection part 21 is arranged at the bottom of the vehicle body 1, and is used to buffer and absorb the acceleration and impact force at the moment of the vehicle landing, which will not be described in detail here.

[0046] As an implementation method, Figure 2 , Figure 3 As shown, the protection portion 21 is a hollow structure.

[0047] By providing the protection part 21 with a hollow structure, the weight and production cost of the protection part 21 can be reduced.

[0048] like Figure 3 As shown, the protection portion 21 includes a plurality of transverse beams 211 , a plurality of vertical beams 212 , and a plurality of connecting plates 213 .

[0049] Among them, multiple cross beams 211 are arranged in sequence at intervals along the length direction of the protective part 21, multiple vertical beams 212 are perpendicular to and cross-arranged with the multiple cross beams 211, and are respectively connected to the multiple cross beams 211, and the adjacent multiple cross beams 211 and multiple vertical beams 212 are surrounded to form a mesh hollow, and the multiple mesh hollows are adjacently arranged to form a hollow structure.

[0050] The multiple horizontal beams 211 and the multiple vertical beams 212 are perpendicular to each other and arranged at intervals, so as to form a plurality of adjacent mesh hollows. The multiple mesh hollows constitute a hollow structure, which is not only structurally reasonable but also has a strength that meets production requirements.

[0051] Furthermore, the horizontal beam 211 and the vertical beam 212 are both round tube beams that are common and easy to purchase on the market, and the horizontal beam 211 and the vertical beam 212 are formed as a whole by welding, which will not be described in detail here.

[0052] As an implementation method, Figures 2 to 4 As shown, a plurality of connection holes are respectively opened on opposite sides of the two energy absorbing parts 22 , and the connection holes are arranged in one-to-one correspondence with the cross beams 211 , and the cross beams 211 are connected to the energy absorbing parts 22 via the connection holes.

[0053] By providing a connection hole on the energy absorbing portion 22 , the protection portion 21 can be mounted on the energy absorbing portion 22 .

[0056] As another preferred implementation, Figure 2 As shown, a striking end 214 is formed downwardly in the middle of the cross beam 211 , and the bottom of the striking end 214 protrudes from the plane where the bottom of the energy absorbing portion 22 is located.

[0057] The impact end 214 protrudes from the plane where the bottom of the energy absorbing part 22 is located, so that when the vehicle body 1 lands, the impact end 214 lands first and transmits the instantaneous acceleration and impact force to the energy absorbing part 22. Such a structure is conducive to energy transmission.

[0058] As an implementation mode, the energy absorbing portion 22 is elastic, and a grid-shaped energy absorbing gap is formed on the inner wall of the energy absorbing portion 22 .

[0059] Through the grid-like energy-absorbing gaps, the energy-absorbing portion 22 after elastic compression can absorb the acceleration and impact force at the moment of vehicle landing.

[0060] like Figure 5 , Figure 6 As shown, the connecting portion 31 is formed with a snap-fit ​​hook groove 311, and the snap-fit ​​portion 32 includes a snap-fit ​​seat 321, a snap-fit ​​ring 322 and a rotating ring 323. The snap-fit ​​seat 321 is connected to the side wall of the energy absorbing portion 22, the snap-fit ​​ring 322 is arranged relative to the snap-fit ​​hook groove 311, and is hinged to the snap-fit ​​seat 321, the rotating ring 323 is hinged to the snap-fit ​​ring 322, and is rotatably connected to the snap-fit ​​seat 321, for driving the snap-fit ​​ring 322 to snap into the snap-fit ​​hook groove 311.

[0061] Through the hinged structure composed of the clamping seat 321 , the clamping ring 322 and the rotating ring 323 , the rotating ring 323 can drive the clamping ring 322 to clamp with the clamping groove after rotation, thereby realizing a detachable connection between the connecting portion 31 and the clamping seat 321 .

[0062] Specifically, the matching structure between the connecting part 31 and the clamping part 32 in the present device is a lock bracket and lock matching structure that is common and easy to purchase on the market. The lock bracket is welded to the vehicle body 1, and the lock is welded to the energy absorbing part 22. Through the locking bracket and the lock matching and clamping, a detachable connection between the vehicle body 1 and the energy absorbing part 22 can be achieved, which will not be elaborated here.

[0063] As an implementation method, Figure 1 , Figure 2 As shown, there are four connecting components 3 in the protective energy absorbing device, two connecting components 3 form a group, and two groups of connecting seats are respectively arranged on the two opposite sides of the two energy absorbing parts 22 and are respectively connected to the two energy absorbing parts 22.

[0064] Four connection components 3 are respectively disposed on both sides of the vehicle body 1 to improve the stability of the connection between the vehicle body 1 and the energy absorbing part 22 .

[0065] The utility model also provides an airdrop vehicle, comprising a vehicle body 1 and a protective energy absorbing device.

[0066] The specific working process of the utility model is as follows: a protective part 21 is arranged below the vehicle body 1, two energy absorbing parts 22 are arranged on both sides of the protective part 21 and are connected to the protective part 21, at least two connecting parts 31 are respectively connected to both sides of the vehicle body 1, and a clamping part 32 is arranged relative to the connecting part 31 and can be clamped with the connecting part 31, so as to detachably connect the protective part 21 and the energy absorbing part 22 to the vehicle. Compared with the prior art, by arranging the protective part 21 and the energy absorbing part 22 below the vehicle body 1, the protective part 21 and the energy absorbing part 22 are used to buffer and absorb the acceleration and impact force of the vehicle at the moment of landing, so as to avoid damage to the vehicle, and at the same time, by clamping the connecting component 3 with the vehicle body 1 and the energy absorbing part 22, a detachable connection between the protective part 21 and the energy absorbing part 22 and the vehicle body 1 is realized, so as to facilitate installation and disassembly by the user.

[0067] When in use, the user first connects the protective part 21 and the energy absorbing part 22 to form a whole, then places the whole formed by the protective part 21 and the energy absorbing part 22 under the vehicle body 1, and sets the impact end 214 away from the vehicle body 1, and then welds the connecting part 31 and the clamping part 32 to the vehicle body 1 and the energy absorbing part 22 respectively, and finally connects the whole formed by the protective part 21 and the energy absorbing part 22 to the vehicle body 1 through the clamping between the connecting part 31 and the clamping part 32.

[0068] Furthermore, after completing the airdrop mission, the user only needs to release the clamping connection between the connecting portion 31 and the clamping portion 32 to separate the vehicle body 1 from the protective portion 21 and the energy absorbing portion 22, which is simple to operate and easy to use.

[0069] The device, through the above structure, can solve the technical problem in the prior art that the vehicle is damaged due to the acceleration and impact force at the moment of landing when the vehicle is airdropped to the ground by a transport aircraft.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
