[0028] Specifically, the contact plate 4 and the partition plate 5 and the first energy absorbing tube 50 on the contact plate 4 absorb the impact energy first. Under the impact, the partition plate 5 and the first energy absorbing tube 50 are broken to absorb the energy. After the first energy absorbing tube 50 and the partition plate 5 are completely broken, if the impact energy has not been completely absorbed, the energy is transferred to the plunger spring 3 through the contact plate 4 to offset the energy. At the same time, the contact plate 4 moves backward to compress the energy absorbing box 6 to absorb energy. The secondary energy absorbing component serves as the last layer of energy absorbing components and performs energy absorbing operation after the energy absorbing box 6 has finished absorbing energy and is completely damaged.

[0029] Embodiment 2

[0030] like Figure 1-6 As shown, the secondary energy absorption component includes a secondary energy absorption frame 7 arranged between the energy absorption box 6 and the mounting plate 1, and a secondary energy absorption groove 70 is arranged in the secondary energy absorption frame 7. The cross-section of the secondary energy absorption groove 70 is cross-shaped, and the cross-section of the secondary energy absorption groove 70 gradually increases as the depth continues to deepen. Energy absorption spring plates 9 are evenly arranged in the secondary energy absorption frame 7, and the energy absorption spring plates 9 are arranged in an arc shape. Spacer foam is arranged between the energy absorption spring plates 9.

[0031] Embodiment 3

[0032] like Figure 1-6 As shown, the energy absorbing spring plate 9 is arranged through the secondary energy absorbing frame 7. In order to reliably install the energy absorbing spring plate 9, the secondary energy absorbing groove 70 is arranged in a cross shape, and the cross-section is continuously increased in the process of increasing depth, and then the size of the energy absorbing spring plate 9 is continuously increased, thereby improving the energy absorption effect. The energy absorbing spring plates 9 are positioned and installed by spacing foam.

[0033] Embodiment 4

[0034] like Figure 1-6 As shown, the first energy absorbing tube 50 and the second energy absorbing tube 60 are hexagonal hollow columns, the first energy absorbing tube 50 is made of plastic, the thickness of the first energy absorbing tube 50 is one millimeter, the material of the second energy absorbing tube 60 is foamed aluminum, the energy absorbing box 6 is arranged in a cross shape, the outer wall of the energy absorbing box 6 is surrounded by aluminum plate, and the second energy absorbing tube 60 is evenly filled in the interior of the energy absorbing box 6.

[0035] Specifically, Figure 2 and Figure 4 As shown, the first energy absorbing tube 50 and the second energy absorbing tube 60 are hexagonal hollow columns, which have better energy absorption effect when impacted. The outer wall of the energy absorbing box 6 is surrounded by aluminum plate to prevent the second energy absorbing tube 60 from spilling out after breaking, and the aluminum plate can reliably transfer the absorbed impact energy to the secondary energy absorbing frame 7.

[0036] Embodiment 5

[0037] like Figure 1-6 As shown, the back of the contact plate 4 is evenly provided with long strip grooves, and the long strip grooves can reduce the overall weight of the contact plate 4. The end of the plunger spring 3 is provided with a buffer plate 30, and the buffer plate 30 is rotatably connected to the plunger spring 3. The buffer plate 30 is connected to an energy-absorbing slider 51 slidably installed on the back of the contact plate 4. The contact plate 4 is provided with a mounting groove 53 at the position of the energy-absorbing slider 51, and the mounting groove 53 is connected to the energy-absorbing groove 52. The energy-absorbing slider 51 is slidably installed with the energy-absorbing groove 52, and a preload spring is provided between the energy-absorbing slider 51 and the energy-absorbing groove 52.

[0038] Specifically, Figure 3 As shown, a groove is provided on the back of the contact plate 4 to reduce the weight of the vehicle, reduce energy consumption and shorten the braking distance. The energy of the plunger spring 3 is absorbed through the contact between the buffer plate 30 and the energy-absorbing slider 51. During the energy absorption process of the plunger spring 3, the plunger spring 3 will rotate. The energy-absorbing slider 51 is slidably installed in the energy-absorbing groove 52. While increasing the rotational displacement, the energy absorption effect can be further improved with the help of the preload spring provided in the energy-absorbing groove 52.

[0039] Embodiment 6

[0040] like Figure 1-6 As shown, a wedge-shaped contact surface 54 is provided on the energy absorbing slider 51 , and the angle between the wedge-shaped contact surface 54 and the plunger spring 3 gradually increases as the plunger spring 3 contracts.

[0041] Embodiment 7

[0042] like Figure 1-6 As shown, the material of the secondary energy absorption frame 7 is aluminum, and the top of the secondary energy absorption frame 7 is set to be retracted inward. When the secondary energy absorption frame 7 receives impact energy absorption, the opening is retracted to wrap the energy absorption spring plate 9 evenly arranged inside, and then the impact energy is absorbed by the energy absorption spring plate 9.

[0043] Specifically, Figure 5 As shown, the top opening of the secondary energy absorbing frame 7 is arranged to be retracted inwards, and rolls inwards after the impact to avoid paralysis and falling off of the energy absorbing frame, thereby ensuring reliable energy absorption.

[0044] Specifically, the contact plate 4 is made of aluminum, and the partition plate 5 is made of plastic.

[0045] The working principle of the embodiment of the present invention is:

[0046] like Figure 1-6 As shown, the present invention connects the contact plate 4 and the mounting plate 1 through the plunger spring 3. When the contact plate 4 is impacted, the partition plate 5 on the contact plate 4 and the installed first energy absorption tube 50 first absorb the impact energy. When the impact energy has not been completely absorbed, the plunger spring 3 starts to absorb the energy, and the contact plate 4 moves backward under the drive of the impact energy. The plunger spring 3 contracts and starts to rotate. The energy absorption box 6 on the rear side of the contact plate 4 further absorbs the energy. When the energy absorption box 6 is completely destroyed and there is still impact energy, the energy absorption box 6 as a whole presses the secondary energy absorption frame 7, and the energy absorption spring plate 9 inside the secondary energy absorption frame 7 absorbs energy. During this absorption process, the plunger spring 3 is still absorbing the impact energy. The impact energy absorption structure is layered through the above structure, which is convenient for replacing the corresponding damaged parts after the impact and reducing maintenance costs.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
