Description

Technical Field

[0001] This utility model relates to the field of energy-absorbing box technology, specifically to an energy-absorbing structure for a front crossbeam of an automobile. Background Technology

[0002] The anti-collision beam is an important component of automobile safety and also the component with the highest safety factor and requirements. The traditional method is to connect the anti-collision beam to the front end of the longitudinal beam with an energy-absorbing box. When an impact occurs, the anti-collision beam and the energy-absorbing box absorb the impact energy through deformation and displacement, thereby protecting the safety of the passenger compartment.

[0003] In current technology, when a crash beam is subjected to a large impact force, the energy-absorbing box deforms and absorbs the impact energy. However, when the crash beam is subjected to a minor impact, although the energy-absorbing box does not deform to the naked eye, the impact force is transmitted to the energy-absorbing box through the crash beam. The overall strength of the energy-absorbing box may have changed. Since most energy-absorbing boxes on the market are die-cast, it is difficult to observe minor deformation of the energy-absorbing box with the naked eye. This makes it impossible for maintenance personnel to determine whether the energy-absorbing box needs to be corrected or replaced, causing inconvenience to subsequent maintenance work. Utility Model Content

[0004] The purpose of this invention is to provide an energy-absorbing structure for a front crossbeam of an automobile to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-absorbing structure for a front crossbeam of an automobile, comprising a crash beam and an energy-absorbing box, wherein the energy-absorbing box is fixedly installed on the outer wall of the crash beam, a triggering mechanism is provided on the energy-absorbing box, and an auxiliary mechanism is provided on the triggering mechanism, wherein the triggering mechanism includes:

[0006] A spring, with a crossbar fixedly installed at both ends of the spring;

[0007] A support rod, one end of which is fixedly installed on the outer wall of the crossbar, and the other end of which is fixedly installed on the outer wall of the energy-absorbing box. The support rod can increase the contact area between the spring and the energy-absorbing box, so that the spring can still be squeezed when the energy-absorbing box undergoes slight deformation.

[0008] The inclined rod is fixedly installed on the side wall of the spring plate. By observing whether there is a gap between adjacent inclined rods, it can be determined whether the energy-absorbing box has deformed.

[0009] Preferably, the auxiliary mechanism includes a reinforcing rib, which is fixedly installed on the outer wall of the energy-absorbing box.

[0010] Preferably, the reinforcing rib has an inclined groove.

[0011] Preferably, the inner wall of the inclined rod is slidably connected to an auxiliary rod, and two sets of inclined rods are provided. The two sets of inclined rods are mirror images of the spring plate on both sides of the outer wall of the spring plate with the spring plate as the central axis. The inner walls of the two sets of inclined rods are slidably connected to auxiliary rods, and the two sets of auxiliary rods are in contact with each other.

[0012] Preferably, an L-rod is fixedly installed on the outer wall of the auxiliary rod, and the end of the L-rod away from the auxiliary rod is attached to the inner wall of the inclined groove. The inclined groove can provide guidance for the L-rod.

[0013] Preferably, the reeds are provided in four sets, and the four sets of reeds are respectively located on the outer walls of the energy absorption box, and the inclined rods on the two adjacent sets of reeds are attached together.

[0014] Compared with the prior art, this utility model provides an energy-absorbing structure for a front crossbeam of an automobile, which has the following beneficial effects:

[0015] 1. The energy-absorbing structure of the front crossbeam of this car, when the energy-absorbing box undergoes slight deformation, uses the support rod, in conjunction with the crossbar and spring, to gradually move the inclined rod away from the energy-absorbing box. At this time, the two adjacent sets of inclined rods will separate from each other, creating a gap between them. By observing the gap between the two adjacent sets of inclined rods, it can be determined whether the energy-absorbing box has deformed, allowing maintenance personnel to visually observe the deformation of the energy-absorbing box and determine whether it needs to be corrected or replaced.

[0016] 2. The energy-absorbing structure of the front crossbeam of this car, when the inclined rod gradually moves away from the energy-absorbing box, will cause the auxiliary rod to slide on the inner wall of the inclined rod in conjunction with the reinforcing rib, the inclined groove and the L rod. At this time, the two sets of auxiliary rods will move away from each other. By observing the distance between the two sets of auxiliary rods, the deformation of the energy-absorbing box can be known. Furthermore, by using the auxiliary rods set around the energy-absorbing box, the direction of the deformation of the energy-absorbing box can be known, so that the staff can correct the energy-absorbing box.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: an energy-absorbing structure for a front crossbeam of an automobile, including a crash beam 1 and an energy-absorbing box 2. The energy-absorbing box 2 is fixedly installed on the outer wall of the crash beam 1. A triggering mechanism 3 is provided on the energy-absorbing box 2. By setting the triggering mechanism 3, the slight deformation of the energy-absorbing box 2 can be observed directly. An auxiliary mechanism 4 is provided on the triggering mechanism 3. By setting the auxiliary mechanism 4, the deformation direction of the energy-absorbing box 2 can be determined, so that the staff can correct the energy-absorbing box 2.

[0023] The aforementioned triggering mechanism 3 includes a spring 31, a support rod 32, and an inclined rod 33. Both ends of the spring 31 are fixedly mounted with crossbars 34. Four sets of springs 31 are arranged, each located on the outer wall of the energy-absorbing box 2. One end of the support rod 32 is fixedly mounted on the outer wall of the crossbar 34, and the other end is fixedly mounted on the outer wall of the energy-absorbing box 2. When the energy-absorbing box 2 absorbs impact force and undergoes slight deformation, the deformed energy-absorbing box 2 will compress the support rod 32, causing the support rod 32 to compress the crossbar 34. At this time, the crossbar 34 will compress the spring 31, causing the spring 31 to undergo slight deformation. With slight deformation, the inclined rod 33 is fixedly installed on the side wall of the spring 31. There are two sets of inclined rods 33, which are mirror images of the spring 31 on both sides of the outer wall of the spring 31 with the spring 31 as the central axis. When the spring 31 deforms, it will drive the inclined rod 33 to gradually move away from the energy absorption box 2. At this time, the two adjacent sets of inclined rods 33 will separate from each other, and the inclined rods 33 on the two adjacent sets of spring 31 will stick together. By observing the gap between the two adjacent sets of inclined rods 33, it can be determined whether the energy absorption box 2 has deformed, so that maintenance personnel can judge whether the energy absorption box 2 needs to be corrected or replaced.

[0024] The auxiliary mechanism 4 includes a reinforcing rib 41, which is fixedly installed on the outer wall of the energy-absorbing box 2. The reinforcing rib 41 has a groove 42. The inner walls of the two sets of inclined rods 33 are slidably connected to auxiliary rods 43, and the two sets of auxiliary rods 43 are in contact with each other. By observing the distance between the two sets of auxiliary rods 43, the deformation of the energy-absorbing box 2 can be known. Furthermore, the direction of deformation of the energy-absorbing box 2 can be known through the auxiliary rods 43 set around the energy-absorbing box 2, so that the staff can correct the energy-absorbing box 2. An L-rod 44 is fixedly installed on the outer wall of the auxiliary rod 43. The end of the L-rod 44 away from the auxiliary rod 43 is in contact with the inner wall of the groove 42. When the spring 31 deforms and drives the inclined rod 33 to gradually move away from the energy-absorbing box 2, the inclined rod 33 will drive the auxiliary rod 43 to move synchronously. At this time, the L-rod 44 and the groove 42 can drive the auxiliary rod 43 to slide on the inner wall of the inclined rod 33, and the two sets of inclined rods 33 will move away from each other.

[0025] Working principle: When the anti-collision beam 1 is subjected to a slight impact, the impact force is transmitted to the energy-absorbing box 2 to absorb the impact force. When the energy-absorbing box 2 absorbs the impact force and causes slight deformation, the deformed energy-absorbing box 2 will squeeze the support rod 32, causing the support rod 32 to squeeze the crossbar 34. At this time, the crossbar 34 will squeeze the spring 31, causing the spring 31 to deform slightly. When the spring 31 deforms, it will drive the inclined rod 33 to gradually move away from the energy-absorbing box 2. At this time, the two adjacent sets of inclined rods 33 will separate from each other, resulting in a gap between the two adjacent sets of inclined rods 33. By observing the gap between the two adjacent sets of inclined rods 33, it can be determined whether the energy-absorbing box 2 has deformed, so that maintenance personnel can determine whether the energy-absorbing box 2 needs to be corrected or replaced.

[0026] When the spring 31 deforms and causes the inclined rod 33 to gradually move away from the energy-absorbing box 2, the inclined rod 33 will drive the auxiliary rod 43 to move synchronously. At the same time, the auxiliary rod 43 will drive the L rod 44 to move synchronously. At this time, the L rod 44 will move against the inner wall of the inclined groove 42. Under the guidance of the inclined groove 42, the L rod 44 will push the auxiliary rod 43, causing the auxiliary rod 43 to slide on the inner wall of the inclined rod 33. At this time, the auxiliary rod 43 will gradually move away from the spring 31, so that the two sets of auxiliary rods 43 will move away from each other. By observing the distance between the two sets of auxiliary rods 43, the deformation of the energy-absorbing box 2 can be known. Furthermore, by observing the auxiliary rods 43 set around the energy-absorbing box 2, if one of the four sets of auxiliary rods 43 has a larger gap, it indicates that the energy-absorbing box 2 has a larger degree of collapse. Thus, the direction of the deformation of the energy-absorbing box 2 can be known, so that the staff can correct the energy-absorbing box 2.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
