[0041] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0042] Embodiment one

[0043] The embodiment relates to a rear body structure which can enhance the rear wall assembly structure strength and improve the collapse energy absorption capacity during collision, so as to improve the structure strength of the rear body and improve the safety factor of the whole vehicle.

[0044] In the rear body structure, the end of the rear wall outer plate assembly not only needs to install the rear bumper, but also needs to install rear tail lamp and other structural parts. Since the structure strength of the two ends of the rear wall outer plate assembly is not high, the rear wall outer plate has insufficient collapse capacity under force when the vehicle collides, and a part of the X direction impact force will be directly transmitted to the side wall outer plate, so that the side wall outer plate and other parts are easily damaged, resulting in the increase of the maintenance cost of the side wall outer plate parts.

[0045] Therefore, the embodiment aims at the deficiency of the rear body structure in the prior art, and proposes a new rear body structure. Figures 1 to 4 As shown in the whole structure, the rear body structure of the embodiment comprises a rear wall outer plate 1 and a rear wall outer plate connecting plate 2 connected with the rear wall outer plate 1.

[0046] In the front-rear direction of the whole vehicle, the rear wall outer plate 1 is located at the rear side of the rear wall outer plate connecting plate 2, and a reinforcing member 3 is arranged between the rear wall outer plate 1 and the rear wall outer plate connecting plate 2. Moreover, the reinforcing member 3 is connected with the rear wall outer plate 1 and the rear wall outer plate connecting plate 2, and the reinforcing member 3 can be collapsed to absorb energy when the vehicle collides.

[0047] At this time, in the above structure, the reinforcing member 3 is arranged in the cavity 10 formed by the rear wall outer plate 1 and the rear wall outer plate connecting plate 2, so that the reinforcing member 3 is connected with the rear wall outer plate 1 and the rear wall outer plate connecting plate 2. In this way, the rear wall outer plate 1 and the rear wall outer plate connecting plate 2 increase the support in the front-rear direction of the whole vehicle, that is, the X direction, by means of the reinforcing member 3, thereby playing a role in strengthening and solidifying the rear wall outer plate 1 region, that is, enhancing the structural strength of the rear wall assembly. Meanwhile, the reinforcing member 3 can be collapsed when the vehicle collides, so that the collision energy can be effectively guided to the position where the reinforcing member 3 is located to be collapsed and absorbed, thereby reducing the risk of damage to the side wall outer plate and other components during the collision and improving the safety factor of the whole vehicle.

[0048] Based on the above overall structure, in detail, referring to Figures 1 to 4 and combining Figure 6 It can be seen that, in the embodiment, the rear wall assembly comprises a rear wall inner plate, a rear wall outer plate 1 and a rear wall outer plate connecting plate 2 in structure. The two rear wall outer plate connecting plates 2 are arranged at intervals in the left-right direction of the whole vehicle, and the two rear wall outer plate connecting plates 2 are connected to the two ends of the rear wall inner plate respectively. The rear wall outer plate connecting plate 2 and the rear wall inner plate are connected with the rear wall outer plate 1.

[0049] Moreover, in the front-rear direction of the whole vehicle, the two rear wall outer plate connecting plates 2 and the rear wall inner plate are located at the front side of the rear wall outer plate 1, that is, the rear wall outer plate 1 is located at the rear side of the rear wall outer plate connecting plate 2 and the rear wall inner plate. The rear wall outer plate 1 and the two rear wall outer plate connecting plates 2 form cavities 10 therebetween, and the rear wall outer plate 1 and the rear wall inner plate form a cavity therebetween. The cavity and the cavities 10 are communicated to form a through cavity, and the through cavity extends along the left-right direction of the whole vehicle. In the embodiment, the above-mentioned reinforcing member 3 is arranged in the cavity 10 formed between the rear wall outer plate 1 and the rear wall outer plate connecting plate 2, and the reinforcing member 3 is connected with the rear wall outer plate 1 and the rear wall outer plate connecting plate 2.

[0050] It should be noted that, Figures 1 to 3Only the connection structure between the rear outer panel connecting plate 2 and the rear outer panel 1 on the right side of the whole vehicle is shown, and the reinforcing member 3 is arranged in the cavity 10 between the rear outer panel connecting plate 2 and the rear outer panel 1 on the right side. The connection structure between the rear outer panel connecting plate 2 and the rear outer panel 1 on the left side of the whole vehicle is not shown, which is symmetrical to the connection structure between the rear outer panel connecting plate 2 and the rear outer panel 1 on the right side, and the cavity 10 between the rear outer panel connecting plate 2 and the rear outer panel 1 on the left side is also provided with the reinforcing member 3. The embodiment is specifically described in detail as an exemplary structure. Figures 1 to 3

[0051] Of course, it can be understood that the reinforcing member 3 can be arranged only in the cavity 10 formed between the rear outer panel connecting plate 2 and the rear outer panel 1 on the right side, or only in the cavity 10 formed between the rear outer panel connecting plate 2 and the rear outer panel 1 on the left side, which is also possible.

At this time, the reinforcing member 3 is arranged in a stepped structure, which is beneficial to energy absorption in collapse, and the position of the reinforcing member 3 can also realize secondary energy absorption when the rear outer panel 1 absorbs energy in collapse, thereby weakening the collision energy.

[0053] Specifically, as a preferred, the reinforcing member 3 includes a main plate 32, and a first lap plate 31 and a second lap plate 33 arranged at opposite ends of the main plate 32. Among them, the first lap plate 31, the main plate 32 and the second lap plate 33 are arranged in a stepped structure, and the first lap plate 31 is connected with the rear outer panel 1, and the second lap plate 33 is connected with the rear outer panel connecting plate 2.

[0054] In the embodiment, the first lap plate 31 and the second lap plate 33 are respectively connected with the rear outer panel 1 and the rear outer panel connecting plate 2, which has a simple structure and is beneficial to ensuring the reliability of the connection between the reinforcing member 3 and the rear outer panel 1 and the rear outer panel connecting plate 2. And the first lap plate 31, the main plate 32 and the second lap plate 33 are arranged in a stepped structure, which also has the characteristics of simple structure, easy to process and low cost, and at the same time, the thickness and material of the reinforcing member 3 can be flexibly adjusted according to different collision grades, thereby facilitating the development difficulty of the rear outer panel 1.

[0055] ​​​In actual implementation, the first lap plate 31 and the second lap plate 33 are integrally formed at both ends of the main plate 32. The main plate 32 is arranged in the cavity 10 in a substantially vertical manner, the first lap plate 31 extends to the left side of the whole vehicle, and the second lap plate 33 extends to the right side of the whole vehicle. In addition, the outer edge of the first lap plate 31 is aligned or tends to be aligned with the end edge of the rear outer panel 1, so as to facilitate the welding connection between the first lap plate 31 and the rear outer panel 1.

[0056] In the embodiment, referring to Figure 5 and combining Figure 7 and Figure 8 It can be seen that the rear outer panel connecting plate 2 has the first plate body 21 and the second plate body 22 connected thereto, wherein the first plate body 21 is arranged in a vertical manner, and the second plate body 22 is connected to the top end of the first plate body 21 and is arranged in a slanting manner towards the rear upper side of the vehicle. At this time, in order to match the contour shape of the rear side of the rear outer panel connecting plate 2, the second lap plate 33 includes the upper lap plate 331 and the lower lap plate 332.

[0057] The avoiding gap 200 is formed between the upper lap plate 331 and the lower lap plate 332, and the avoiding gap 200 corresponds to the connection position of the first plate body 21 and the second plate body 22. The upper lap plate 331 is connected to the second plate body 22, and the lower lap plate 332 is connected to the first plate body 21. In this way, not only the forming and preparation of the first lap plate 31 are facilitated, but also the reliability of the connection between the first lap plate 31 and the rear outer panel connecting plate 2 can be further ensured.

[0058] On the basis of the stepped structure of the reinforcing member 3 provided with the first lap plate 31, the main plate 32 and the second lap plate 33, in the embodiment, as a preferred mode, the first reinforcing rib 301 is arranged at the connection position between the first lap plate 31 and the main plate 32. The arrangement of the first reinforcing rib 301 is beneficial to improve the structural strength of the reinforcing member 3 itself.

[0059] It should be noted that in addition to the first reinforcing rib 301 arranged at the connection position between the first lap plate 31 and the main plate 32, a second reinforcing rib 301 can also be arranged at the connection position between the second lap plate 33 and the main plate 32, which is also beneficial to improve the structural strength of the reinforcing member 3 itself. Of course, the first reinforcing rib 301 and the second reinforcing rib 301 can also be arranged on the reinforcing member 3, which is also feasible.

[0060] Referring to Figure 7 and Figure 8In the embodiment, the reinforcing member 3 is provided with a positioning portion 302, which is used to position the reinforcing member 3 relative to the rear outer panel 1 or the rear outer panel connecting plate 2. The positioning portion 302 is beneficial to the positioning of the reinforcing member 3, so as to ensure the position accuracy of the reinforcing member 3 relative to the rear outer panel 1 or the rear outer panel connecting plate 2.

[0061] It is worth mentioning that when the reinforcing member 3 and the rear outer panel connecting plate 2 are connected into an assembly first, the rear outer panel connecting plate 2 is positioned on a fixture, and then the reinforcing member 3 is also positioned on the fixture through the positioning portion 302, so as to ensure the relative position of the reinforcing member 3 on the rear outer panel connecting plate 2. Then, the rear outer panel 1 is connected with the reinforcing member 3. In this way, the relative position of the reinforcing member 3 on the rear outer panel 1 can be ensured on the premise of ensuring the relative position of the reinforcing member 3 on the rear outer panel connecting plate 2.

[0062] When the reinforcing member 3 and the rear outer panel 1 are connected into an assembly first, the rear outer panel 1 is positioned on a corresponding fixture, and then the reinforcing member 3 is also positioned on the fixture through the positioning portion 302, so as to ensure the relative position of the reinforcing member 3 on the rear outer panel 1. Then, the rear outer panel connecting plate 2 is connected with the reinforcing member 3. In this way, the relative position of the reinforcing member 3 on the rear outer panel connecting plate 2 can be ensured on the premise of ensuring the relative position of the reinforcing member 3 on the rear outer panel 1. In the embodiment, the reinforcing member 3 and the rear outer panel connecting plate 2 are connected into an assembly first as a preferred implementation form.

[0063] Specifically, the positioning portion 302 includes a positioning hole arranged on the main plate 32. In specific implementation, the positioning hole is inserted or screwed with a positioning member on a corresponding fixture, so as to position the reinforcing member 3 on the corresponding fixture.

[0064] In the embodiment, the reinforcing member 3 is connected with the rear outer panel 1 and the rear outer panel connecting plate 2 by welding as a preferred implementation form, and the rear outer panel connecting plate 2 is provided with a welding through hole 201. In this way, the reinforcing member 3 is connected by welding, and the welding through hole 201 is arranged on the rear outer panel 1. On one hand, the connection reliability between the reinforcing member 3 and the rear outer panel 1 and the rear outer panel connecting plate 2 can be ensured. On the other hand, the welding through hole 201 is beneficial to the welding operation of the reinforcing member 3, because a welding gun of a welding device can pass through the welding through hole 201. In specific implementation, the first lap plate 31 is connected with the rear outer panel 1 by welding, and the second lap plate 33 is connected with the rear outer panel connecting plate 2 by welding.

[0065] As a preferred embodiment, in this embodiment, the rear outer panel 1 and the rear outer panel connecting plate 2 are provided with a beam mounting portion 100 for mounting a rear beam, and the reinforcing member 3 is arranged close to the beam mounting portion 100. In this way, the structural strength of the position of the beam mounting portion 100 can be improved, and the reinforcing member 3 can be used to absorb energy during a collision, reducing the transmission of collision force to the vehicle interior.

[0066] Specifically, the beam mounting portion 100 is arranged on the rear outer panel 1 and the corresponding rear outer panel connecting plate 2 in the vehicle transverse direction, and the two ends of the rear beam are connected to the left and right beam mounting portions 100. Moreover, each beam mounting portion 100 is arranged at the lower position where the rear outer panel 1 is connected to the corresponding rear outer panel connecting plate 2, and each beam mounting portion 100 includes a mounting hole that penetrates the rear outer panel 1 and the rear outer panel connecting plate 2, and the mounting hole is arranged in multiple.

[0067] Looking back Figure 1 and Figure 2 As shown in the figure, in this embodiment, the rear outer panel 1 is connected to the body side panel 6, and the rear outer panel connecting plate 2 is connected to the D-pillar 5. At this time, when the collision force is transmitted to the D-pillar 5, the structural strength of the D-pillar 5 can be used to weaken the impact force, making the body outer cover such as the side panel less likely to deform, and ensuring that the body fixture does not deform during a low-speed collision.

[0068] Moreover, in terms of specific structure, the rear outer panel 1 is connected to the body side panel 6 through the tail lamp mounting plate 4. In this way, by separately preparing the rear outer panel 1 and the tail lamp mounting plate 4, and then connecting the rear side of the rear outer panel 1 and the body side panel 6 through the tail lamp mounting plate 4, on the one hand, the single-piece structure of the rear outer panel 1 and the tail lamp mounting plate 4 is relatively simple, facilitating processing and preparation, and on the other hand, it is conducive to achieving a relatively complex structure shape of the rear part of the vehicle body.

[0069] In this embodiment, the D-pillar 5 has a D-pillar inner panel 51 and a gutter plate 52, the lower end of the D-pillar inner panel 51 is connected to the rear outer panel connecting plate 2, and the lower end of the gutter plate 52 is connected to the rear outer panel 1 and the tail lamp mounting plate 4. In this way, the D-pillar 5 can better cooperate with the parts of the rear part of the vehicle body, which is conducive to dispersing the impact force and reducing the risk of deformation of the vehicle body.

[0070] In specific implementation, in this embodiment, the D-pillar inner panel 51 is made of high-strength steel plate. At this time, when the collision force is transmitted to the D-pillar 5, the impact force can be effectively weakened, and the risk of deformation of the outer cover of the vehicle body can be reduced. The cooperation of the reinforcing member 3 arranged in the cavity 10 formed by the rear outer panel 1 and the rear outer panel connecting plate 2 with the D-pillar 5 can achieve a gradual weakening of the collision force, a gradual decrease of the energy, and an effective combination of high-strength bearing, thereby solving the problem of severe deformation of the D-pillar 5 of the vehicle body during a rear collision of the vehicle body, which leads to severe deformation of the trunk and high passenger injury value.

[0071] The rear body structure of the embodiment can play a role of strengthening and solidifying the rear quarter outer panel 1 region through the reinforcing member 3, and can effectively guide the collision energy to the position where the reinforcing member 3 is located to collapse and absorb energy, thereby reducing the risk of damage to the side wall outer panel and other components during collision and improving the safety factor of the vehicle.
