[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0042] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the structure of the crushing member 1 provided in an exemplary embodiment of the present disclosure. An embodiment of the present application provides a crushing member 1. The crushing member 1 includes a body 12. The body 12 is provided with a crushing energy-absorbing structure 13 and a sound-absorbing structure 14.

[0043] It can be understood that the crushing member 1 is applied to an energy-absorbing box, and the energy-absorbing box is arranged at the front of the vehicle and is connected to the front anti-collision beam.

[0044] It can be understood that the crushing energy-absorbing structure 13 can be a slot hole structure provided on the crushing member 1.

[0045] It can be understood that there can be various noise elimination structures 14. For example, when using resistive noise elimination, the noise elimination structure 14 can be made of an absorption material, and the absorption material can be fiberglass, steel fiber, etc. These materials can absorb the acoustic wave energy, thereby reducing the noise.

[0046] For another example, the noise elimination structure can also be a structure with an expansion chamber and a partition, so that when the sound wave propagates in the noise elimination structure, they can interfere with each other to achieve the purpose of reducing noise.

[0047] For yet another example, the noise elimination structure 14 can also be a plurality of hole structures, so that when the sound wave passes through the hole structure, the frequency spectrum of the sound wave is broadened, thereby reducing the audible components and reducing the audible noise.

[0048] In this embodiment, by providing a noise elimination structure on the crushing member 1, on the one hand, the outer shell 21 of the muffler and the outer shell 21 of the energy-absorbing muffler 2 can be shared, thereby reducing the number of parts required for the vehicle; on the other hand, the noise elimination structure can be disposed adjacent to the engine of the vehicle, that is, disposing the noise elimination structure on the crushing member 1 can make the noise elimination structure arranged at the front of the vehicle, thereby shortening the length of the exhaust pipe 41 and reducing the number of parts required to fix the exhaust pipe 41. Thus, it can promote the lightweight design of the vehicle.

[0049] Moreover, on the basis that the noise elimination is combined with the crushing member 1 to reduce the number of parts required for the vehicle, the vehicle has space available for the arrangement of other components, thereby increasing the volume of the energy-absorbing muffler 2 to enhance the protection ability of the energy-absorbing muffler 2 for the rear components and the occupants. And, based on the increase in the volume of the energy-absorbing muffler 2, the width of the crash beam 31 connected thereto can also be increased, as well as its contact area with the trolley wall barrier under the MPDB (Multi-Purpose Dynamic Barrier) condition, reducing the SD (Standard Deviation) value and improving the MPDB condition result, so as to better protect structures such as the rear tires.

[0050] Please refer to Figure 1 , in some embodiments, the noise elimination structure 14 includes a plurality of noise elimination holes 15 provided on the body 12. In this way, the noise elimination structure 14 is simple to manufacture and can control the weight of the crushing member 1, which is beneficial to the lightweight design of the vehicle.

[0051] Please refer to Figure 1 , in some embodiments, the plurality of noise elimination holes 15 are distributed in a matrix.

[0052] Specifically, the sound-absorbing structure 14 includes multiple groups of sound-absorbing holes 15, and each group of sound-absorbing holes 15 includes multiple sound-absorbing holes 15 arranged at intervals in a direction perpendicular to the ground. The multiple sound-absorbing holes 15 are distributed at intervals in a direction parallel to the horizontal plane on the body 12.

[0053] In some embodiments, the cross-sectional shape of the sound-absorbing hole 15 is at least one of the following shapes: circular, oval, polygon. In this way, the structure of the sound-absorbing hole 15 is simple and easy to manufacture, thereby reducing the manufacturing cost.

[0054] Optionally, the cross-sectional shape of the sound-absorbing hole 15 is circular, as Figure 1 shown.

[0055] Please refer to Figure 1 , in some embodiments, the axes of the multiple sound-absorbing holes 15 are parallel to each other. In this way, the uniformity of sound absorption at each part of the crushable member 1 can be improved, so that the uniformity of noise absorption by the crushable member 1 can be improved, thereby improving the noise reduction effect.

[0056] In addition, the axes of the multiple sound-absorbing holes 15 being parallel to each other can also simplify the design to reduce the manufacturing difficulty.

[0057] In some embodiments, the axis of the sound-absorbing hole 15 is perpendicular to the surface of the body 12 where its orifice is located.

[0058] In this embodiment, through the above settings, the sound-absorbing hole 15 can be processed and positioned based on the main body, thereby reducing the manufacturing difficulty of the crushable member 1 to improve the processing efficiency.

[0059] Please refer to Figure 2 , Figure 2 is a side view of the crushable member 1 provided in an exemplary embodiment of the present disclosure. In some embodiments, the crushable energy-absorbing structure 13 includes a crush guiding groove 13a. The crush guiding groove 13a has a notch 131 and a bottom wall 132 of the groove. The width dimension W1 of the notch 131 is greater than the width dimension W2 of the bottom wall 132 of the crush guiding groove 13a. In this way, not only can the collapse direction of the crushable member 1 be controlled to effectively ensure that the crushable member 1 can collapse and deform in a predetermined direction during a collision, so as to more effectively absorb and disperse the collision energy, but also the structure of the crushable energy-absorbing structure 13 is simple and easy to manufacture.

[0060] It can be understood that no sound-absorbing holes 15 are arranged on the groove wall of the crush guiding groove 13a.

[0061] Exemplarily, the main body is a flat plate structure, and its middle part is bent multiple times to form the crush guiding groove 13a.

[0062] Please refer to Figure 3 , Figure 3 is Figure 2An enlarged view of portion A in [Chinese]. In some embodiments, the crush guiding groove 13a further has a groove sidewall 133. The included angle between the groove sidewall 133 and the groove bottom wall 132 of the crush guiding groove 13a is α, satisfying: 120° ≤ α ≤ 150°.

[0063] Exemplarily, the included angle α includes, but is not limited to, 120°, 126°, 128°, 130°, 132°, 135°, 138°, 140°, 142°, 145°, 148°, 150°.

[0064] In this embodiment, by limiting the included angle α, on the one hand, it can be avoided that the included angle is too large, resulting in a poor guiding effect on the collapse deformation of the crush member 1, so as to effectively ensure that the crush member 1 can collapse and deform in a predetermined direction; on the other hand, it can be avoided that the included angle is too small, resulting in a small deformation amount of the crush member 1, so that the crush member 1 has a high energy absorption effect.

[0065] Please refer to Figure 3 , in some embodiments, the depth dimension of the crush guiding groove 13a is d, satisfying: 6 mm ≤ d ≤ 10 mm.

[0066] Exemplarily, the depth dimension d includes, but is not limited to, 6 mm, 6.5 mm, 7 mm, 7.3 mm, 7.6 mm, 8 mm, 8.5 mm, 8.8 mm, 9 mm, 9.16 mm, 9.3 mm, 9.6 mm, 9.7 mm, 10 mm.

[0067] In this embodiment, by limiting the depth dimension d, on the one hand, it can be avoided that its depth is too large, resulting in the crush member 1 being more likely to deform, so as to ensure that the crush member 1 has a high energy absorption effect; on the other hand, it can be avoided that the depth is too small, resulting in a large deformation difficulty, so as to effectively ensure that the collapse deformation can proceed smoothly.

[0068] Please refer to Figures 4 to 6 , Figure 4 is a schematic structural diagram of the energy-absorbing silencer 2 provided in an exemplary embodiment of the present disclosure, Figure 5 is a schematic structural diagram of the energy-absorbing silencer 2 from another perspective provided in an exemplary embodiment of the present disclosure, Figure 6It is a schematic diagram of the internal structure of the energy-absorbing muffler 2 provided in an exemplary embodiment of the present disclosure. Correspondingly, an embodiment of the present application also provides an energy-absorbing muffler 2, which includes a housing 21 and the aforementioned crush member 1. The housing 21 has an inner cavity 211. An air inlet hole 212 and an exhaust hole 213 communicating with the inner cavity 211 are provided on the housing 21. The crush member 1 is disposed in the inner cavity 211 and is connected to the cavity wall of the inner cavity 211. The crush member 1 is located between the air inlet hole 212 and the exhaust hole 213. Among them, the inner cavity 211, the sound-absorbing structure 14, the air inlet hole 212, and the exhaust hole 213 together define an exhaust passage 214.

[0069] It can be understood that when the sound-absorbing structure 14 is a sound-absorbing hole 15, the sound-absorbing hole 15 allows gas to flow through, and it can form a part of the exhaust passage 214.

[0070] Exemplarily, the crush member 1 is welded to the cavity wall of the inner cavity 211.

[0071] Specifically, when the main body is a plate-like structure, one side faces the air inlet hole 212, and the other side faces the exhaust hole 213.

[0072] In this embodiment, by using the crush member 1 provided in some embodiments of the present application, on the one hand, the housing 21 of the muffler and the housing 21 of the energy-absorbing muffler 2 can be shared, thereby reducing the number of parts required for the vehicle configuration; on the other hand, the sound-absorbing structure can be arranged adjacent to the engine of the vehicle, that is, arranging the sound-absorbing structure on the crush member 1 can make the sound-absorbing structure layout at the front of the vehicle head, thereby shortening the length of the exhaust pipe 41 and reducing the number of parts required to fix the exhaust pipe 41. In this way, it can promote the lightweight design of the vehicle.

[0073] Please refer to Figure 6 , in some embodiments, there are multiple crush members 1, and the multiple crush members 1 are sequentially arranged at intervals between the air inlet hole 212 and the exhaust hole 213.

[0074] In this embodiment, arranging multiple crush members 1, on the one hand, can increase the energy absorption efficiency, thereby being able to more effectively absorb the collision energy; on the other hand, it can control the collapse direction to reduce the damage to other components of the vehicle.

[0075] Please refer to Figure 6 , in some embodiments, there are two crush members 1, and the crush energy absorption structure 13 includes a crush guiding groove 13a, and the crush guiding grooves 13a of the two crush members 1 are arranged in opposite directions. In this way, it helps to distribute the collision energy more evenly on the two crush plates, and the uniform energy distribution can improve the overall stability and reliability of the energy-absorbing muffler 2, ensuring that the energy can be continuously and effectively absorbed during the collision process, thereby making the energy absorption effect of the energy-absorbing muffler 2 better.

[0076] Please refer toFigure 7 , Figure 7 is a schematic structural view of the anti-collision assembly 3 provided in an exemplary embodiment of the present disclosure. Correspondingly, an embodiment of the present application also provides an anti-collision assembly 3. The anti-collision assembly 3 includes an anti-collision beam 31 and two energy-absorbing mufflers 2. The anti-collision beam 31 has a concave surface 32. The two energy-absorbing mufflers 2 are located at both ends of the concave surface 32 and are both connected to the anti-collision beam 31. At least one of the energy-absorbing mufflers 2 is the aforementioned energy-absorbing muffler 2.

[0077] Optionally, the anti-collision beam 31 is a front anti-collision beam 31 of an automobile.

[0078] In this embodiment, by using the energy-absorbing muffler 2 provided in some embodiments of the present application, on the one hand, the outer shell 21 of the muffler and the outer shell 21 of the energy-absorbing muffler 2 can be shared, so that the number of parts required for the automobile can be reduced; on the other hand, the sound-absorbing structure can be arranged adjacent to the engine of the automobile, that is, arranging the sound-absorbing structure on the crushable member 1 can make the sound-absorbing structure layout at the front of the vehicle head, so as to shorten the length of the exhaust pipe 41 and reduce the number of parts required to fix the exhaust pipe 41. In this way, the lightweight design of the automobile can be promoted.

[0079] Please refer to Figure 4 and Figure 7 , in some embodiments, a stepped groove 215 is provided on the side of the energy-absorbing muffler 2 facing the anti-collision beam 31. The end of the anti-collision beam 31 is inserted into the stepped groove 215.

[0081] Please refer to Figure 4 and Figure 8 , in some embodiments, the anti-collision assembly 3 further includes a bolt 33. A connecting ear 218 is provided on the side of the second groove wall 217 away from the first groove wall 216. The end of the rod portion of the bolt 33 passes through the connecting ear 218 and is threadedly connected to the anti-collision beam 31.

[0082] Specifically, there are two connecting ears 218, and bolt 33 through-holes 2181 are provided on both of the two connecting ears 218. The end of the rod portion of bolt 33 passes through bolt 33 through-hole 2181 and is threadedly connected to bumper beam 31.

[0083] Exemplarily, a threaded hole 219 is provided on one side of the first groove wall 216 away from the second groove wall 217. The end of the rod portion of bolt 33 passes through bumper beam 31 and is connected to this threaded hole 219.

[0084] In this embodiment, by providing connecting ears 218, on the one hand, the mating surface between the energy-absorbing silencer 2 and the bumper beam 31 can be increased to improve the mating stability therebetween. On the other hand, by connecting the energy-absorbing silencer 2 and the bumper beam 31 at the connecting ears 218, the connection reliability therebetween can be improved.

[0087] In this embodiment, by adopting the bumper assembly 3 of some embodiments of the present application, on the one hand, the outer shell 21 of the silencer and the outer shell 21 of the energy-absorbing silencer 2 can be shared, thereby reducing the number of parts required for the vehicle; on the other hand, the silencing structure can be arranged adjacent to the engine of the vehicle, that is, arranging the silencing structure on the crushable member 1 can make the silencing structure arranged at the front of the vehicle head, thereby shortening the length of the exhaust pipe 41 and reducing the number of parts required to fix the exhaust pipe 41.
