Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically relates to an energy absorbing member for a vehicle, a vehicle energy absorbing structure and a vehicle. Background Art

[0002] As vehicles become more and more popular, vehicle safety issues are receiving more and more attention from users. In frontal conditions, a 25% small offset collision causes the barrier to directly hit the tire because of the small overlap with the anti-collision beam, and the tire directly hits the A-pillar of the vehicle body, causing the A-pillar to be directly stressed. Due to the loss of the resistance of the front anti-collision beam, the force on the A-pillar will increase sharply. For models with a small A-pillar cross-section, it is difficult to resist the load of a small offset collision.

[0003] At present, the main response measure for the body to deal with small offset collision conditions is to adopt hard resistance measures, that is, to resist the collision load by strengthening the structure of the A-pillar. However, the energy absorption effect of receiving the collision load only through the A-pillar is poor, and the A-pillar is easily deformed and damaged after a collision, resulting in reduced safety of the entire vehicle.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0041] The energy absorbing member, the vehicle energy absorbing structure and the vehicle provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0042] See also Figures 1 to 15 , an energy absorbing member 30, comprising: a first energy absorbing portion 31, the first energy absorbing portion is used to be connected to the A-pillar 1; a second energy absorbing portion 32, the second energy absorbing portion 32 is used to be connected to the wheel cover; wherein the A-pillar 1 and the wheel cover are connected to each other.

[0043] In actual applications, the A-pillar 1, the upper side beam 2, the longitudinal beam 3 and the door sill 6 are connected to each other. When a small offset collision occurs with an obstacle, there are generally two force transmission paths on the vehicle body. Path 1: The barrier is transmitted to the upper side beam 2, and the upper side beam 2 is then transmitted to the A-pillar 1. Path 2: The barrier is transmitted to the tire, and the tire is transmitted to the A-pillar 1.

[0044] In the embodiment of the present application, the energy absorbing member 30 is configured to absorb energy or transmit force, and can absorb part of the collision energy, while guiding the collision load to be transmitted to the door sill 6 through the wheel arch, which can effectively reduce the collision load transmitted to the A-pillar 1, and has the beneficial effect of preventing the upper end of the A-pillar from being damaged during the collision.

[0045] Specifically, the first energy absorbing part 31 is connected to the A-pillar, the second energy absorbing part 32 is connected to the wheel cover, and the A-pillar 1 and the wheel cover are connected to each other. In actual application, when a small offset collision occurs, the collision load from the tire is transmitted to the wheel cover, and the second energy absorbing part 32 connected to the wheel cover will resist the collision load from the tire for the first time. Further, the collision load continues to be transmitted to the A-pillar 1, and the first energy absorbing part 31 connected to the A-pillar 1 can resist the collision load transmitted to the A-pillar 1. It can be understood that since the second energy absorbing part 32 and the first energy absorbing part 31 resist at least part of the collision load transmitted to the A-pillar 1 in the transmission path, that is, the collision energy transmitted from the tire to the A-pillar 1 is absorbed, the collision energy transmitted to the A-pillar 1 is reduced, the A-pillar is effectively protected, and the collision bearing capacity of the A-pillar and the whole vehicle is improved, thereby improving the safety of the whole vehicle.

[0046] Optionally, in the embodiment of the present application, the energy absorbing member 30 also includes an energy absorbing box 33; the first energy absorbing portion 31 and the second energy absorbing portion 32 enclose a first cavity, and the first energy absorbing portion 31 and the second energy absorbing portion 32 both extend along the length direction of the A-pillar 1; one end of the first energy absorbing portion 31 is flush with the upper end of the tire, and the other end extends to the lower end of the door sill 6; one end of the second energy absorbing portion 32 is flush with the upper end of the tire, and the other end extends to the upper end of the door sill 6, and the door sill 6 and the wheel cover are correspondingly arranged; the energy absorbing box 33 is crimped to one end of the first energy absorbing portion 31 close to the door sill 6, and is connected to the wheel cover.

[0047] In the embodiment of the present application, the second energy absorbing part 32 and the first energy absorbing part 31 can be welded together to form a first cavity, and the first cavity has a certain degree of collapse. The setting of the first cavity can absorb the collision load from the tire during a small offset collision, which has the beneficial effect of preventing the A-pillar 1 from being damaged during the collision. Furthermore, the second energy absorbing part 32 and the first energy absorbing part 31 are both flush with the upper end of the tire and extend at least to the upper end of the door sill 6. The above setting can increase the contact area between the energy absorbing part 30 and the tire, and has a stronger energy absorption effect. In particular, the first energy absorbing part 31 extends from the upper end to the lower end of the door sill 6, and the second energy absorbing part 32 extends to the upper end of the door sill 6, reserving installation space for the energy absorbing box 33. The energy absorption box 33 is crimped to one end of the first energy absorption portion 31 close to the door sill 6 and is indirectly connected to the A-pillar 1. In actual application, when a small offset collision occurs, the energy absorption box 33 can absorb the collision load from the tire on the one hand, and can also transfer the collision load to the door sill 6 on the other hand. The above-mentioned load absorption and load transfer have the beneficial effect of preventing the A-pillar 1 from being damaged during the collision.

[0048] Furthermore, the energy absorption box 33 may be made of cast aluminum and may have a certain hollow structure, which can effectively reduce the weight of the energy absorption box 33 and will not excessively increase the burden on the entire vehicle while achieving energy absorption.

[0049] It should be noted that the second energy absorbing member 20 protrudes from the A-pillar 1 to form a second cavity and the energy absorbing member 30 protrudes from the A-pillar 1 to form a first cavity. The arrangement of the second cavity and the first cavity can not only absorb the collision energy but also thicken the A-pillar 1, further improving the ability of the A-pillar 1 to withstand the collision load.

[0050] Optionally, in an embodiment of the present application, the energy absorption box 33 is provided with a plurality of mounting holes 331, and the plurality of mounting holes 331 are evenly distributed. The energy absorption box 33 also includes a plurality of mounting members 332, and the mounting members 332 pass through the mounting holes 331 and the first energy absorption part 31 to be connected to the wheel cover; the energy absorption box 33 is arranged opposite to the door sill 6, and along the direction perpendicular to the door sill 6, the projection of the energy absorption box 33 covers the projection of the door sill 6; wherein the mounting holes 331 and the mounting members 332 are arranged in a one-to-one correspondence.

[0051] In the embodiment of the present application, the installation hole 331 and the installation member 332 are provided to realize the connection between the energy absorption box 33, the first energy absorption part 31 and the A-pillar 1. The energy absorption box 33 arranged opposite to the door sill 6 can directly absorb the collision energy from the tire and opposite to the door sill 6, and the cross-sectional size of the energy absorption box 33 is consistent with the door sill 6, so that the collision load received by the energy absorption box 33 can be transmitted to the door sill 6. The arrangement of the energy absorption box 33 can absorb the collision energy opposite to the door sill 6 on the one hand, and can enhance the force transmission effect of the door sill 6 on the other hand, thereby reducing the collision load received by the A-pillar 1.

[0052] It should be noted that the energy absorption box 33 may be provided with three mounting holes 331 for connection with the mounting member 332. Accordingly, the first energy absorption part 32 and the A-pillar 1 are also provided with corresponding openings for connection with the mounting member 332, and the connection is achieved through the mounting holes 331 and the openings. Specifically, the mounting member 332 may be a bolt.

[0053] Furthermore, a plurality of multi-rib structures radiating in the form of a "spider web" may be provided based on the mounting holes 331, and this structure has the beneficial effect of improving the strength and stability of the energy absorption box.

[0054] Optionally, in an embodiment of the present application, a vehicle energy absorption structure is provided, including a reinforcement 10 and an energy absorption member 30 as described above, wherein the reinforcement 10 is fixedly connected to the energy absorption member 30, one end of the reinforcement 10 is connected to the longitudinal beam 3, and the other end is connected to the A-pillar 1, and the reinforcement 10 is arranged toward the tire, and the longitudinal beam 3 is arranged on the lower side of the A-pillar 1.

[0055] In the embodiment of the present application, the reinforcement 10 is used to connect the A-pillar 1 and the longitudinal beam 3, and is arranged toward the tire. The reinforcement 10 is arranged to resist the collision load on the tire, and can also transfer the collision load on the A-pillar to the longitudinal beam 3. At the same time, the arrangement of the reinforcement 10 strengthens the connection between the A-pillar and the wheel cover, which can prevent the A-pillar and the wheel cover from being torn off during a collision, thereby ensuring the integrity of the vehicle body. Through the fixed connection between the reinforcement 10 and the energy absorbing member 30 (such as welding, or other fixing methods), the reinforcement has the beneficial effect of reducing or preventing the risk of tearing of the energy absorbing member 30.

[0056] Optionally, in an embodiment of the present application, the reinforcement 10 includes a longitudinal beam reinforcement 11 and a longitudinal beam connector 12, and the longitudinal beam 3 includes a front longitudinal beam 4 and a rear longitudinal beam 5 that are connected to each other; one end of the longitudinal beam reinforcement 11 is connected to the front longitudinal beam 4, and the other end is connected to the A-pillar 1, and the longitudinal beam reinforcement 11 is arranged toward the tire; the longitudinal beam connector 12 is connected to a side of the rear longitudinal beam 5 that faces the tire, and the longitudinal beam reinforcement 11 and the longitudinal beam connector 12 are connected to each other.

[0057] In the embodiment of the present application, the longitudinal beam reinforcement 11 is provided to enhance the strength of the longitudinal beam 3. In practical applications, due to the small offset collision barrier, the tire will directly contact the tire, and the tire will contact the lower end of the A-pillar 1 and the rear end of the wheel cover under the pressure of the barrier. If the cross-section of the lower end of the A-pillar 1 is small, it is difficult to resist the above-mentioned pressure, and the wheel cover is also difficult to resist. The longitudinal beam reinforcement 11 is connected to the A-pillar 1 and the front longitudinal beam 4 and is arranged toward the tire. When a small offset collision occurs, the longitudinal beam reinforcement 11 can directly resist the collision load brought by the tire, and can also transfer the collision load on the A-pillar 1 to the front longitudinal beam 4. In addition, the longitudinal beam connector 12 is connected to the side of the rear longitudinal beam 5 facing the tire, and the longitudinal beam reinforcement 11 and the longitudinal beam connector 12 are connected to each other, so that the longitudinal beam reinforcement 11 further indirectly strengthens the connection between the A-pillar 1 and the rear longitudinal beam 5, and the longitudinal beam reinforcement 11 is arranged toward the tire, which can enhance the sheet metal strength of the wheel cover, so that the longitudinal beam reinforcement 11 can prevent the A-pillar 1 and the wheel cover from being torn off during a collision, which has the beneficial effect of ensuring the integrity of the vehicle body.

[0058] Optionally, in an embodiment of the present application, the longitudinal beam reinforcement 11 includes at least two reinforcing ribs 111 , which extend along the length direction of the A-pillar 1 , one end of the reinforcing rib 111 is connected to the front longitudinal beam 4 , and the other end of the reinforcing rib 111 is connected to the A-pillar 1 .

[0059] In the embodiment of the present application, the reinforcing rib 111 is connected between the longitudinal beam 3 and the A-pillar 1, and extends along the length direction of the A-pillar 1. In actual application, the reinforcing rib 111 is arranged on the back of the wheel arch. When a small offset collision occurs, the tire transfers the collision load to the wheel arch. The arrangement of the reinforcing rib 111 improves the strength of the wheel arch, prevents the A-pillar 1 from being torn off from the wheel arch during a collision, and has the beneficial effect of ensuring the integrity of the vehicle body.

[0060] Optionally, in the embodiment of the present application, it also includes: a second energy absorbing member 20, the second energy absorbing member 20 is connected to the upper end of the A-pillar 1 away from the tire, the second energy absorbing member 20 protrudes from the A-pillar 1 to form a second cavity, and the second cavity is used to absorb collision energy.

[0061] In the embodiment of the present application, the second energy absorbing member 20 is connected to the upper end of the A-pillar 1 away from the tire, and protrudes from the A-pillar 1 to form a second cavity. The second cavity is used to absorb the collision load transmitted to the upper side beam 2, thereby reducing the transmission of the collision load to the A-pillar 1, and has the function of protecting the A-pillar 1.

[0062] Furthermore, the reinforcing component 10, the second energy absorbing member 20 and the energy absorbing member 30 are arranged in multiple energy absorbing areas. By absorbing the collision energy or transmitting force in the multiple energy absorbing areas, the collision load transmitted to the A-pillar 1 can be effectively reduced, and the risk of tearing of the energy absorbing member 30 can be prevented, which has the beneficial effect of preventing the A-pillar 1 from being damaged during the collision.

[0063] Optionally, in an embodiment of the present application, the second energy absorbing member 20 includes a front end reinforcement plate 21 on the A-pillar, a lower reinforcement plate 22 on the A-pillar, an upper reinforcement plate 23 on the A-pillar and an inner plate 24 on the A-pillar. The front end reinforcement plate 21 on the A-pillar and the inner plate 24 on the A-pillar are connected along the length direction of the A-pillar, the lower reinforcement plate 22 on the A-pillar and the inner plate 24 on the A-pillar are connected, the front end reinforcement plate 21 on the A-pillar and the lower reinforcement plate 22 on the A-pillar enclose a second cavity, and the lower reinforcement plate 22 on the A-pillar and the inner plate 24 on the A-pillar are both connected to the upper reinforcement plate 23 on the A-pillar.

[0064] In an embodiment of the present application, the front end reinforcement plate 21 on the A-pillar can be overlapped on the lower reinforcement plate 22 of the A-pillar by welding, and the front end reinforcement plate 21 on the A-pillar and the lower reinforcement plate 22 of the A-pillar are enclosed to form a second cavity, and the second cavity has a certain collapse formation. The setting of the second cavity can absorb the collision energy during a small offset collision process, thereby effectively reducing the collision load transmitted to the A-pillar 1, which has the beneficial effect of preventing the A-pillar 1 from being damaged during the collision process.

[0065] Furthermore, the A-pillar upper reinforcement plate 23 can simultaneously connect and wrap the A-pillar upper front reinforcement plate 21 and the A-pillar lower reinforcement plate 22 to form a stable joint structure, thereby improving the stability of the overall structure of the second energy absorbing member 20 .

[0066] Optionally, in an embodiment of the present application, it also includes: an upper side beam 2, which is connected to the end of the A-pillar 1 away from the wheel arch, and the front end reinforcement plate 21 on the A-pillar and the upper side beam 2 are arranged opposite to each other, and along the length direction of the A-pillar, the length of the front end reinforcement plate 21 on the A-pillar is greater than the opening of the upper side beam 2.

[0067] In the embodiment of the present application, the upper side beam 2 is connected to the end of the A-pillar away from the wheel arch, and the front end reinforcement plate 21 on the A-pillar is arranged opposite to the upper side beam 2. In actual application, when a small offset collision occurs, the collision load is transmitted to the upper side beam 2 and then to the front end reinforcement plate 21 on the A-pillar. Along the length direction of the A-pillar 1, the length of the front end reinforcement plate 21 on the A-pillar is set to be greater than the length of the opening of the upper side beam 2. It can absorb as much energy as possible transmitted from the upper side beam 2, thereby having the beneficial effect of reducing the collision load on the A-pillar 1.

[0068] Optionally, in the embodiment of the present application, the roof rail 2 includes a horizontal portion and a deformation portion that are connected to each other, and the deformation portion and the second energy absorbing component 20 are arranged side by side in a direction perpendicular to the A-pillar 1 .

[0069] In the embodiment of the present application, when a collision occurs, the deformation part can deform to absorb the collision energy. The deformation part is set to absorb the collision energy and reduce the collision load transmitted to the second energy absorbing member 20. In the actual collision load transmission process, the collision load passing through the deformation part and the second energy absorbing member 20 will gradually decrease and then be transmitted to the A-pillar 1, which has the beneficial effect of protecting the A-pillar 1 from being damaged during the collision process.

[0070] Furthermore, the deformation part can be an opening set in the upper side beam 2, or it can be a bending structure. When a small deviation collision occurs, the deformation part with the opening or the bending structure is deformed by force to absorb the collision energy and reduce the collision load transmitted to the second energy absorbing member 20.

[0071] Optionally, in the embodiment of the present application, the support strength of the front end reinforcement plate 21 on the A-pillar is lower than the support strength of the lower reinforcement plate 22 on the A-pillar.

[0072] In the embodiment of the present application, the A-pillar upper front reinforcement plate 21 can be made of a material with a lower support strength, so that the A-pillar upper front reinforcement plate 21 can achieve the effect of crushing and absorbing energy during a collision. The A-pillar lower reinforcement plate 22 can be made of a material with a higher support strength to resist body deformation.

[0073] Specifically, the material design of the front end reinforcement plate 21 on the A-pillar can be a steel material with lower strength, while the corresponding A-pillar lower reinforcement plate 22 is designed to be a steel material with higher strength. Furthermore, the structure of the above different materials can make the structure enclosed to form the second cavity form a structure with soft front and hard rear, the front part is used to absorb energy, and the rear part is used to resist collision load and prevent body deformation. Therefore, this structure can effectively reduce the collision load transmitted to the A-pillar 1 and improve the safety performance of the body.

[0074] Optionally, in an embodiment of the present application, a vehicle is also provided, comprising a front vehicle energy absorbing structure.

[0075] In the embodiment of the present application, energy-absorbing structures that can absorb collision energy are arranged at multiple locations. Specifically, a second energy-absorbing member 20 is arranged at the upper end of the A-pillar, an energy-absorbing member 30 is arranged at the lower end of the A-pillar, a reinforcement member is arranged on the longitudinal beam 3, and an energy-absorbing portion is arranged on the upper side beam 2. The above arrangement can be used to absorb the collision energy in path one and path two, that is, the collision energy in the force transmission path from the absorption barrier to the upper side beam 2, and then the upper side beam 2 transmits it to the A-pillar 1, and the collision energy in the force transmission path from the absorption barrier to the tire, and then the tire transmits it to the A-pillar 1. In the above force transmission process, it can also resist the collision load on the one hand and reduce the transmission of the collision load on the other hand. It can also transmit the collision load to the door sill 6 with a larger cross-section, reduce the pressure borne by the A-pillar, and thereby avoid damage to the A-pillar in the event of a small offset collision.
