[0035] In recent years, the number of automobiles in use has been continuously increasing. As the main participants in road traffic, various rear-end collision accidents of automobiles are common. When an automobile has a rear-end collision accident, the rear bumper and the anti-collision beam play a crucial role in protecting the occupants in the vehicle. For the vehicle body structure, the rear bumper and the anti-collision beam are the last line of defense to protect other more important load-bearing structures and drive structures in the vehicle body, and are the main means of passive protection for the automobile.
[0036] However, according to the applicant's observation and research, when designing the bumper and anti-collision beam at the rear end of the automobile, in order to protect the bottom longitudinal beam structure of the automobile, energy-absorbing boxes need to be provided at both ends of the anti-collision beam. These energy-absorbing boxes are used to absorb impact energy. Generally, these energy-absorbing boxes are mainly designed for the purpose of protecting the occupants in the vehicle and the bottom longitudinal beam. However, when the automobile suffers a rear-end collision accident, this design is difficult to protect the components at the rear end of the automobile from being damaged. This is because there is a certain gap between the rear bumper and the anti-collision beam, and the external force impact will easily cause the outer shell at the rear end of the automobile to deform greatly. Moreover, the rear bumper and the anti-collision beam have a relatively high stiffness, and when being impacted, it will cause the vehicle body to vibrate greatly. The obvious deformation and large vibration on the outer shell at the rear end of the automobile are both likely to cause components such as the parking sonar and retroreflector at the rear end of the automobile to fall off or be damaged.
[0037] Based on this, the present utility model proposes a collision energy-absorbing device to solve or at least alleviate the above technical problems.
[0038] Please refer to Figures 1 to 4, in an embodiment of the present utility model, the collision energy absorption device 100 is applied to an automobile, and it includes a connecting body 1, a supporting body 2 and a connecting member 3. Among them, the connecting body 1 includes a first side surface 11 disposed close to the anti-collision beam 200 of the automobile; the top of the supporting body 2 is connected to the bottom of the connecting body 1, and the supporting body 2 includes a second side surface 21 attached to the anti-collision beam 200; the second side surface 21 and the first side surface 11 are in the same geometric plane; or, the second side surface 21 and the first side surface 11 are parallelly disposed, and the second side surface 21 protrudes towards the anti-collision beam 200 compared with the first side surface 11; in addition, one end of the connecting member 3 is disposed on the first side surface 11, and the other end is connected to the anti-collision beam 200.
[0039] Specifically, the bumper at the rear of the vehicle is arranged on the outer side of the anti-collision beam 200 of the vehicle. That is to say, the bumper is closer to the end of the vehicle rear than the anti-collision beam 200, and there is a certain gap between the bumper and the anti-collision beam 200. The collision energy absorption device 100 in this embodiment is not installed at both ends of the anti-collision beam 200, but is installed on the anti-collision beam 200 and the whole collision energy absorption device 100 is located in the gap between the anti-collision beam 200 and the bumper, and extends along the length direction of the anti-collision beam 200. One side of the connecting body 1 close to the anti-collision beam 200 is the first side surface 11, and one side of the supporting body 2 close to the anti-collision beam 200 is the second side surface 21. The supporting body 2 and the connecting body 1 are tightly connected to form a whole, so as to increase the stress area and overall strength of the collision energy absorption device 100, which is more conducive to the diffusion of impact energy and improves the energy absorption effect. In addition, the connecting piece 3 is arranged on the first side surface 11, and a mounting hole for installing the connecting piece 3 is correspondingly opened on the anti-collision beam 200. The connecting piece 3 is inserted into the hole to install the connecting body 1 and the supporting body 2 on the anti-collision beam 200. Considering the installation process and cost, the connecting body 1 is generally hung on the anti-collision beam 200 through the connecting piece 3. This setting will cause the connection between the connecting body 1 and the anti-collision beam 200 to become loose during daily driving, which is not conducive to maintaining the working stability of the collision energy absorption device 100. By connecting the supporting body 2 and the connecting body 1, and connecting the second side surface 21 on the supporting body 2 to fit the anti-collision beam 200, the anti-collision beam 200 can provide a supporting force perpendicular to the second side surface 21 direction to the supporting body 2. Used in cooperation with the connecting piece 3, the installation of the supporting body 2 and the connecting body 1 is more stable, so as to improve the working stability of the collision energy absorption device 100. In addition, there are two types of positional relationships between the supporting body 2 and the connecting body 1 and the anti-collision beam 200. In one case, the first side surface 11 of the connecting body 1 and the second side surface 21 of the supporting body 2 are located on the same geometric plane. The geometric plane includes a plane and a curved surface with a certain curvature. The specific shape of the geometric plane is set according to the shape of the anti-collision beam 200 of the vehicle. On this basis, the second side surface 21 is arranged to fit the anti-collision beam 200, so that both the first side surface 11 and the second side surface 21 are close to the anti-collision beam 200. This setting can enable the anti-collision beam 200 to fully provide a supporting reaction force to the supporting body 2 and the connecting body 1, so that the displacement of the connecting body 1 and the supporting body 2 in the direction of the anti-collision beam 200 is small, the deformation of the vehicle rear when it is collided is small, and thus the possibility of the components at the vehicle rear falling off is reduced.In another case, the second side surface 21 of the support body 2 is attached to the anti-collision beam 200, while there is a certain gap between the first side surface 11 of the connection body 1 and the anti-collision beam 200. This gap serves as a buffer space for the connection body 1 after being subjected to an external force, so as to improve the overall energy absorption effect of the collision energy absorption device 100, reduce the vibration generated during a collision. At the same time, the first side surface 11 and the second side surface 21 are arranged in parallel, so that after the first side surface 11 is extruded by an external force onto the anti-collision beam 200, it can closely adhere to the anti-collision beam 200 as much as possible, enabling the anti-collision beam 200 to provide a support reaction force to the connection body 1.
[0040] The principle of the collision energy absorption device 100 having an energy absorption effect lies in its ability to undergo collapse deformation, which includes plastic deformation, fracture, and fragmentation of the collision energy absorption device 100. When external collision energy is input into the collision energy absorption device 100, the voids inside it are compressed, and plastic deformation gradually accumulates. When the stress in the collision energy absorption device 100 reaches the limit, fracture occurs at the stress concentration part of the collision energy absorption device 100. At this time, the stress is released, and the collision energy absorption device 100 can continue to be compressed, and the external collision energy is gradually absorbed. When the fractured collision energy absorption device 100 still cannot completely absorb the external collision energy, as the internal stress increases, the collision energy absorption device 100 gradually undergoes fragmentation. After fragmentation, the collision energy absorption device 100 no longer has the ability to undergo collapse deformation, and at this time, it cannot continue to absorb external collision energy.
[0041] In the technical solution provided by the present utility model, the collision energy absorption device 100 includes a connection body 1, a support body 2, and a connecting member 3. Among them, the connection body 1 includes a first side surface 11 disposed close to the anti-collision beam 200 of the vehicle; the top of the support body 2 is connected to the bottom of the connection body 1, and the support body 2 includes a second side surface 21 attached to the anti-collision beam 200; the second side surface 21 and the first side surface 11 are in the same geometric plane; or, the second side surface 21 and the first side surface 11 are arranged in parallel, and the second side surface 21 protrudes towards the anti-collision beam 200 compared to the first side surface 11; one end of the connecting member 3 is disposed on the first side surface 11, and the other end is connected to the anti-collision beam 200. Since the collision energy absorption device 100 is installed outside the anti-collision beam 200, and two main body structures, namely the connection body 1 and the support body 2, are provided, when the vehicle tail is impacted, the impact energy can be dispersed and transmitted to the connection body 1 and the support body 2, and the second side surface 21 is attached to the anti-collision beam 200, enabling the anti-collision beam 200 to fully provide a support reaction force to the support body 2 and the connection body 1, so that the collision energy absorption device 100 has a better buffer energy absorption effect, and further can reduce the deformation and vibration intensity of the vehicle tail, and finally reduce the probability of the vehicle tail components falling off or being damaged.
[0042] Furthermore, in an embodiment of the present utility model, the connecting body 1 is provided with a buffer groove 12. The buffer groove 12 includes a buffer space and an opening, and the opening is provided on the first side surface 11. As a preferred solution, please refer to Figure 2 , the first side surface 11 and the second side surface 21 are arranged on the same geometric plane. Meanwhile, a buffer groove 12 is arranged on one side of the first side surface 11 of the connecting body 1, so that the buffer groove 12 is recessed from the first side surface 11 towards the side away from the anti-collision beam 200. The length direction of the buffer groove 12 is the same as the length direction of the connecting body 1. The size of the buffer groove 12 needs to consider the strength and stiffness requirements of the connecting body 1 at the same time. In this embodiment, the buffer groove 12 is used to provide a buffer space for the connecting body 1. When the connecting body 1 is impacted, the buffer groove 12 can allow the connecting body 1 to undergo elastic deformation and a part of plastic deformation, thereby improving the overall energy absorption effect of the collision energy absorption device 100. Through this setting, not only can a buffer space be provided between the connecting body 1 and the anti-collision beam 200, but also the first side surface 11 and the second side surface 21 can be both attached to the anti-collision beam 200. Under the action of the collision energy absorption device 100 in this embodiment, when the rear end of the vehicle is impacted, it can avoid generating large vibrations and reduce the deformation degree of the rear end of the vehicle after being impacted.
[0043] Still further, in an embodiment of the present utility model, a reinforcing rib 121 is arranged in the buffer space along the length direction of the buffer space. Please refer to Figure 2 , the reinforcing rib 121 is arranged throughout the buffer space. At least one side is arranged on the side of the reinforcing rib 121 close to the first side surface 11. In a plane perpendicular to the length direction of the buffer space, the projection of the reinforcing rib 121 can be set as a part of a rectangle, a part of a polygon or a sector. Through this setting, it can play a role in strengthening the connecting body 1, improve the overall stiffness of the connecting body 1, and thus reduce the degree of intrusion of other structures into the rear end of the vehicle after being impacted.
[0044] In addition, in an embodiment of the present utility model, the supporting body 2 is further provided with an energy absorption groove 22. Please refer to Figure 5 , the energy absorption groove 22 is arranged on the side of the supporting body 2 away from the anti-collision beam 200, and the number of the energy absorption grooves 22 is multiple. The multiple energy absorption grooves 22 are arranged at equal intervals along the length direction of the supporting body 2. A cavity with the same function as the buffer space is formed inside the energy absorption groove 22. When the rear of the vehicle is impacted, this cavity can accommodate the elastoplastic deformation of the supporting body 2 and play a certain buffering role. At the same time, due to the phenomenon of stress concentration around the cavity, the energy absorption groove 22 can guide the collapse direction of the rest of the collision energy absorption device 100, thereby playing a role in improving the overall energy absorption effect of the collision energy absorption device 100.
[0045] In an embodiment of the present utility model, a first buffer cavity is provided inside the connection main body 1, and a second buffer cavity is provided inside the support main body 2. By providing cavities inside both the connection main body 1 and the support main body 2, the energy absorption efficiency of the collision energy absorption device 100 is improved and the collision energy absorption process is improved, so that when a collision occurs, energy is dispersed and absorbed through deformation, thereby reducing the harm brought to the vehicle occupants by the impact, and at the same time facilitating the lightweight design of the collision energy absorption device 100. Among them, the projected shape of the first buffer cavity and the second buffer cavity on a plane perpendicular to the length direction of the connection main body 1 includes one of a rectangle, a "field" shape, a "U" shape, an "Ω" shape, and a "hui" shape.
[0046] In an embodiment of the present utility model, the number of the connecting members 3 is at least two, and at least two connecting members 3 are symmetrically arranged along the central axis of the connection main body 1. Please refer to Figure 2 With Figure 6 , in order to improve the installation stability of the connection main body 1 and the support main body 2, the number of the connecting members 3 is at least set to two. In this embodiment, the number of the connecting members 3 is two, and the positions of the connecting members 3 are arranged on both sides of the first side surface 11 close to the edge of the connection main body 1, and the two connecting members 3 are symmetrically arranged along the central axis of the connection main body 1. Among them, the central axes of the connection main body 1 and the support main body 2 are coincidentally arranged. Through this setting, it is beneficial for the collision energy absorption device 100 to maintain moment balance when installed on the anti-collision beam 200 and improve the stability during daily use.
[0047] In addition, in an embodiment of the present utility model, at least two of the connecting members 3 include a compensation member 3a and a standard member 3b, and the width of the compensation member 3a is smaller than the width of the standard member 3b. The surplus gap between the standard member 3b and the hole wall of the installation hole on the anti-collision beam 200 is usually small, which is set to 1.5 mm in this embodiment, so that the standard member 3b can be just installed in the installation hole, while the compensation member 3a is used to overcome the influence of manufacturing and installation errors. Its height is usually the same as that of the standard member 3b, but the width needs to be smaller than the width of the standard member 3b, so that the surplus gap between it and the hole wall of the installation hole is larger, so as to make up for the installation errors of other standard members 3b, which is beneficial to improving the installation efficiency of the collision energy absorption device 100.
[0048] Among them, please refer to Figure 2 , the cross-section of the standard member 3b is set to a four-leaf clover shape, that is, on any plane perpendicular to the length direction of the standard member 3b, the projection of the standard member 3b is a four-leaf clover shape. This setting makes it more convenient for the standard member 3b to be inserted into the installation hole of the anti-collision beam 200. During installation, only the upper edge and the lower edge in the four-leaf clover shape need to be in contact with the upper and lower hole walls of the installation hole, so that the standard member 3b can ignore the influence of manufacturing accuracy during installation, and can greatly improve the installation efficiency of the collision energy absorption device 100. Among them, installation holes with different sizes are respectively provided on the anti-collision beam 200 corresponding to the standard member 3b and the compensation member 3a.
[0049] In an embodiment of the present utility model, the collision energy absorption device 100 further includes an auxiliary stabilizer 4. The auxiliary stabilizer 4 includes a connecting portion 41 and a fixing portion 42. The connecting portion 41 is disposed on the top surface of the connecting body 1, and the fixing portion 42 is connected to the anti-collision beam 200. Please refer to Figure 1 , one end of the auxiliary stabilizer 4 is disposed in a fitting manner with the top surface of the anti-collision beam 200. Please refer to Figure 2 and Figure 6 , the auxiliary stabilizer 4 is used to assist in stabilizing the connection between the connecting body 1 and the anti-collision beam 200. Among them, the connecting portion 41 is disposed on the top surface of the connecting body 1, and the connection method includes one of integral molding, glue bonding, and snap connection. The fixing portion 42 is integrally formed with the connecting portion 41. After the collision energy absorption device 100 is integrally installed, the fixing portion 42 is in contact with the top surface of the anti-collision beam 200. In this way, relying on the frictional force between the fixing portion 42 and the top surface of the anti-collision beam 200, the collision energy absorption device 100 is more stable when subjected to bumps or external vibration inputs. In another embodiment, the end of the connection between the fixing portion 42 and the anti-collision beam 200 is provided with a barb, and the barb can hook on the side surface of the anti-collision beam 200, and this setting makes the connection between the collision energy absorption device 100 and the anti-collision beam 200 more stable.
[0050] In an embodiment of the present utility model, the connecting body 1, the supporting body 2, and the connecting member 3 are integrally formed parts. The connecting body 1, the supporting body 2, and the connecting member 3 are all integrally formed, and their material is polypropylene. In this embodiment, the foaming ratio of polypropylene is 11 times to achieve a better energy absorption effect suitable for this vehicle model. In other implementations, the foaming ratio of polypropylene should be adjusted adaptively according to the needs of the vehicle model. Through this setting, only one mold needs to be designed to achieve mass production, which is beneficial to reducing production costs.
[0051] The present utility model also proposes an automobile, which includes any one of the collision energy absorption devices 100 in the above embodiments. The specific structure of the collision energy absorption device 100 refers to the above embodiments. Since this automobile adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.
[0052] In an embodiment of the present utility model, please refer to Figure 1 , Figure 3 and Figure 4, the vehicle further includes a bumper beam 200. The collision energy absorption device 100 is installed on the bumper beam 200. The support body 2 in the collision energy absorption device 100 is arranged in contact with the bumper beam 200. The bending arcs of the support body 2 and the connection body 1 are designed according to the bending arc of the bumper beam 200. The connecting member 3 is installed in the installation hole of the bumper beam 200 to connect the connection body 1 with the bumper beam 200.
