[0028] The accompanying drawings, which are included in and constitute a part of the specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, are used to explain the principles of the present invention.

[0030] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0031] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0032] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0033] The longitudinal direction defined in the embodiments of the present invention refers to the height direction of the vehicle, that is, the vehicle Z direction; the left and right direction refers to the lateral direction of the vehicle, that is, the vehicle Y direction; the front and rear direction refers to the forward direction of the vehicle, that is, the vehicle X direction.

[0034] The first embodiment of the utility model provides a rear enclosure structure, such as Figure 1 and Figure 2 As shown, the rear enclosure structure includes a rear enclosure inner panel 1, a rear enclosure outer panel 2 and a rear enclosure reinforcement beam 3, the rear enclosure outer panel 2 and the rear enclosure reinforcement beam 3 are respectively arranged on the longitudinal outer side of the rear enclosure inner panel 1, the upper part of the rear enclosure inner panel 1 and the rear enclosure outer panel 2 are connected to form a first cavity 100, the lower part of the rear enclosure inner panel 1 and the rear enclosure reinforcement beam 3 are connected to form a second cavity 200, and the longitudinal outer side of the rear enclosure inner panel 1 is connected with an anti-collision beam 4.

[0035] The rear enclosure inner panel 1, the rear enclosure outer panel 2 and the rear enclosure reinforcement beam 3 are respectively arranged at the rear of the vehicle to provide support for the rear of the vehicle, and form the interior space of the rear compartment of the vehicle together with the rear floor and the left and right sides. The anti-collision beam 4 refers to the anti-collision beam arranged at the rear of the vehicle. The rear enclosure reinforcement beam 3 is arranged on the longitudinal outer side of the vehicle and is connected to the rear enclosure inner panel 1. Among them, the outer side of the rear enclosure inner panel 1 refers to the side of the rear enclosure inner panel 1 facing the outside of the vehicle. The first cavity 100 formed by the upper part of the rear enclosure outer panel 2 and the rear enclosure inner panel 1 and the second cavity 200 formed by the lower part of the rear enclosure reinforcement beam 3 and the rear enclosure inner panel 1 absorb energy, crush and deform, and improve the collision performance when a collision occurs at the rear of the vehicle. The first cavity 100 improves the collision performance of the upper area of ​​the rear of the vehicle, and the second cavity 200 improves the collision performance of the lower area of ​​the rear of the vehicle. The longitudinal outer side of the rear inner panel 1 is also connected to an anti-collision beam 4, which is used to reduce the collision energy absorbed when the vehicle is hit. The second cavity 200 and the anti-collision beam 4 jointly play a role in absorbing collision energy. Compared with only setting one anti-collision beam 4, setting the second cavity 200 improves the anti-collision performance, thereby minimizing the damage of the impact force to the longitudinal beam of the vehicle body and improving the safety protection performance of the vehicle.

[0036] In some embodiments, the first cavity 100 and the second cavity 200 are spaced apart from each other, which is beneficial to the dispersion of force in the event of a collision, and avoids direct impact on a certain local area to cause damage to the vehicle and cause safety hazards.

[0037] In some embodiments, the longitudinal inner side of the rear inner panel 1 is connected to the floor longitudinal beam, and the second cavity 200, the anti-collision beam 4 and the floor longitudinal beam are located at the same height. The floor longitudinal beam is used to support the floor laid in the rear compartment of the car. The inner side refers to the side facing the interior of the vehicle, specifically, Figure 3As shown, the height of the second cavity 200, the height of the anti-collision beam 4, and the height of the floor longitudinal beam refer to the height of their center lines along the front-rear direction of the vehicle. The second cavity 200, the anti-collision beam 4, and the floor longitudinal beam are set to the same height, and when a rear collision occurs, the energy between the anti-collision beam 4, the second cavity 200, and the floor longitudinal beam is continuously transferred and the energy shows a decreasing trend.

[0038] In some embodiments, Figure 4 As shown, the floor longitudinal beams include a left floor longitudinal beam 5 and a right floor longitudinal beam 6, the left and right sides of the rear inner panel 1 are respectively connected to the left floor longitudinal beam 5 and the right floor longitudinal beam 6, a floor cross beam 7 is connected between the left floor longitudinal beam 5 and the right floor longitudinal beam 6, and the rear inner panel 1, the left floor longitudinal beam 5, the floor cross beam 7 and the right floor longitudinal beam 6 are sequentially connected to form an annular structure. The left and right sides of the rear inner panel 1 refer to the left and right sides along the transverse direction of the vehicle, and the left floor longitudinal beam 5, the right floor longitudinal beam 6 and the floor cross beam 7 are used to support the laid rear floor, so that the rear inner panel 1, the left floor longitudinal beam 5, the floor cross beam 7 and the rear floor longitudinal beam form an annular reinforcement structure, forming a complete rear floor annular structure, thereby improving the strength of the rear part of the vehicle body.

[0039] In some embodiments, Figure 3 As shown, the left and right sides of the anti-collision beam 4 have energy absorption boxes 8 connected to the rear inner plate 1, and the height of the energy absorption box 8 is the same as that of the anti-collision beam 4. The height of the energy absorption box 8 refers to the height of its center line along the front-rear direction of the vehicle. The height of the energy absorption box 8 is the same as that of the anti-collision beam 4, which makes the force transmission channel continuous and the force transmission effect good. Specifically, at least two continuous force transmission channels are formed at the rear of the vehicle, one of which has a force transmission path of: anti-collision beam 4-one of the energy absorption boxes 8-left longitudinal beam 5 of the floor; the other force transmission path is: anti-collision beam 4-another energy absorption box 8-right longitudinal beam 6 of the floor. At the same time, the anti-collision beam 4 has a third cavity 300, and the third cavity 300 and the second cavity 200 form a double energy absorption channel. When a rear collision occurs, the third cavity 300 of the rear anti-collision beam 4 and the second cavity 200 form a double energy absorption structure, which is more conducive to ensuring safety during a rear collision and protecting electrical devices such as batteries or chargers arranged in the trunk.

[0040] For example, at least one of a crush hole and a crush rib is provided on the energy absorption box 8. By providing the energy absorption box 8, when a collision occurs, the energy absorption box 8 can be the first to receive the impact, which can improve the crush absorption capacity of the anti-collision beam 4 and improve the rear collision safety. The energy absorption box 8 is a rectangular body, and the four edges of the energy absorption box 8 are arc-shaped transitions. The crush holes can be provided at the four edges of the energy absorption box 8.

[0041] In some embodiments, the cavity height of the second cavity 200 is greater than the cavity height of the anti-collision beam 4. The height of the second cavity 200 and the cavity height of the anti-collision beam 4 refer to the height of the cross section thereof along the height direction of the vehicle. For example, if the anti-collision beam 4 is a steel beam, the height of the second cavity 200 is greater than the height of the third cavity 300. If the anti-collision beam 4 is an aluminum beam, this requirement is not made.

[0042] In some embodiments, Figure 4 As shown, the rear enclosure reinforcement beam 3 protrudes toward the outside of the vehicle. The rear enclosure reinforcement beam 3 is configured to protrude toward the outside of the vehicle, thereby expanding the volume of the second cavity 200 and improving the buffering and energy absorption effect.

[0043] Specifically, the rear enclosure reinforcement beam 3 is an arc-shaped beam. The area corresponding to the rear enclosure inner panel 1 and the rear enclosure reinforcement beam 3 is also arranged in an arc shape, which is more capable of resisting the rear impact force. For example, the cross section of the rear enclosure reinforcement beam 3 is trapezoidal, the length of the part close to the rear enclosure inner panel 1 is larger, and the length of the part close to the anti-collision beam 4 is smaller, which ensures collision energy absorption while improving the aesthetics of the rear of the vehicle body.

[0044] The rear enclosure outer panel 2 has a plurality of bends. Specifically, since the rear enclosure outer panel 2 is relatively long, a plurality of bends are provided at different positions of the rear enclosure outer panel 2 to strengthen the rear enclosure structure in a targeted manner. For example, since the rear enclosure outer panel 2 needs to withstand rear collisions and the probability of head-on collisions is higher, the central position of the rear enclosure outer panel 2 is set thicker, while the positions on the left and right sides of the rear enclosure outer panel 2 and the rear enclosure inner panel 1 are set thinner. By bending the rear enclosure outer panel 2 multiple times to form a plurality of bends, the rigidity and strength of the rear enclosure structure are improved, the structural reinforcement effect is improved, and the rear collision requirements are met.
