[0027] An embodiment of the present utility model provides a guiding structure 1, on which a first plane 11 and a second plane 12 are provided; the first plane 11 is adapted to be disposed opposite to the front side of the battery pack 2; the second plane 12 is adapted to be disposed opposite to the rear side of the front subframe 3; the second plane 12 is a guiding plane inclined in the vehicle front-rear direction.

[0028] As an example, the guiding structure 1 is used to be disposed between the battery pack 2 and the front subframe 3, and the battery pack 2 and the front subframe 3 are spaced apart in the vehicle front-rear direction. The guiding structure 1 includes a first plane 11 and a second plane 12. The first plane 11 is disposed opposite to the front side of the battery pack 2, and the second plane 12 is disposed opposite to the rear side of the front subframe 3. When the vehicle is impacted in the forward direction and the front subframe 3 moves backward to impact the guiding structure 1, the front subframe 3 can contact the second plane 12; when the guiding structure 1 moves backward under the impact of the front subframe 3, the first plane 11 can contact the battery pack 2, so as to play a role in slowing down. Since the second plane 12 is a guiding plane inclined in the vehicle front-rear direction, it can be inclined upward from front to rear or inclined upward from front to rear. When the front subframe 3 moves backward under collision, the front subframe 3 contacts the second plane 12 and moves along the guiding direction of the second plane 12, so that the front subframe 3 is misaligned with the battery pack 2, avoiding the front subframe 3 from impacting the battery pack 2, so as to achieve the purpose of protecting the battery pack 2.

[0029] In one embodiment, the guiding structure 1 includes a first support plate 13 and a plurality of reinforcing ribs 14 extending forward from the first side surface of the first support plate 13; the second side surface of the first support plate 13 is a first plane 11; the side edges of the plurality of reinforcing ribs 14 away from the first support plate 13 cooperate to form a guiding plane inclined along the front-rear direction of the vehicle.

[0030] As an example, the guiding structure 1 includes a first support plate 13 and a plurality of reinforcing ribs 14 extending forward from the first side surface of the first support plate 13. On each reinforcing rib 14, one side edge located in the front is inclined with respect to the first support plate 13, so that the side edges of the plurality of reinforcing ribs 14 away from the first support plate 13 cooperate to form a guiding plane inclined along the front-rear direction of the vehicle, that is, the second plane 12. In this example, a plurality of reinforcing ribs 14 are provided on the first support plate 13 to ensure the overall stiffness of the guiding structure 1. Moreover, the side edges of the plurality of reinforcing ribs 14 away from the first support plate 13 cooperate to form a guiding plane inclined along the front-rear direction of the vehicle. When the front subframe 3 moves backward under collision, it can guide the front subframe 3 to move upward or downward from front to back, so that the front subframe 3 is misaligned with the battery pack 2, avoiding the front subframe 3 hitting the battery pack 2, so as to achieve the purpose of protecting the battery pack 2.

[0031] In this example, the guiding structure 1 adopts a main structure composed of a first support plate 13 and a plurality of reinforcing ribs 14 extending from the first support plate 13, which can reduce the weight of the guiding structure 1 and the manufacturing cost under the condition of ensuring the guiding function of the guiding structure 1.

[0032] In one embodiment, the guiding structure 1 further includes a second support plate 15 extending forward from the first side surface of the first support plate 13; the second support plate 15 is connected to the upper side edge or the lower side edge of the plurality of reinforcing ribs 14.

[0033] As an example, the guiding structure 1 further includes a second support plate 15 extending forward from the first side surface of the first support plate 13. The number of the second support plates 15 can be one or two. When the number of the second support plates 15 is one, it can be arranged on the upper side of the reinforcing ribs 14 and connected to the upper side edges of the plurality of reinforcing ribs 14, or arranged on the lower side of the reinforcing ribs 14 and connected to the lower side edges of the plurality of reinforcing ribs 14, so that the first support plate 13 and the second support plate 15 cooperate to form a triangular support frame similar to install a plurality of reinforcing ribs 14 to ensure the stiffness of the guiding structure 1; when the number of the second support plates 15 is two, the two second support plates 15 are arranged oppositely and cooperate with the first support plate 13 to form a trapezoidal support frame similar to install a plurality of reinforcing ribs 14 to ensure the stiffness of the guiding structure 1 and improve the anti-impact ability of the guiding structure 1.

[0034] In one embodiment, the guiding structure 1 further includes connecting portions 16 extending outward from both sides of the second support plate 15 in the left-right direction of the vehicle, and the connecting portions 16 are provided with assembly holes.

[0035] As an example, the guiding structure 1 further includes connecting portions 16 extending outward from both sides of the second support plate 15 in the left-right direction of the vehicle. Assembly holes are provided on both connecting portions 16 for assembling fasteners to fix the guiding structure 1 on the vehicle body assembly. For example, the fasteners can be connecting bolts. Each connecting bolt is inserted into an assembly hole, and one end of each connecting bolt can be screwed to the lower vehicle body to assemble the guiding structure 1 on the lower vehicle body. The two connecting bolts can also cooperate to form an anti-rotation structure to prevent the failure phenomenon caused by the self-rotation of the guiding structure 1 during use.

[0036] In one embodiment, the first plane 11 is a profiling plane matching the shape of the battery pack 2.

[0037] As an example, the first plane 11 of the guiding structure 1 is a profiling plane matching the shape of the battery pack 2. When the guiding structure 1 moves backward and contacts the battery pack 2, the profiling plane can be attached to the front side of the battery pack 2, reducing the pressure generated on the surface of the battery pack 2 and preventing the battery pack 2 from being punctured.

[0038] The embodiment of the present invention further provides a vehicle body assembly, including a battery pack 2, a front subframe 3, and the guiding structure 1 in any of the above embodiments; the guiding structure 1 is arranged between the battery pack 2 and the front subframe 3.

[0039] As an example, the vehicle body assembly includes a battery pack 2, a front subframe 3, and the guiding structure 1 in any of the above examples. The guiding structure 1 is arranged between the battery pack 2 and the front subframe 3. The first plane 11 of the guiding structure 1 is arranged opposite to the front side of the battery pack 2, and the second plane 12 of the guiding structure 1 is arranged opposite to the rear side of the front subframe 3. When the vehicle is impacted in the forward direction and the front subframe 3 moves backward and impacts the guiding structure 1, the front subframe 3 can contact the second plane 12; when the guiding structure 1 moves backward under the impact of the front subframe 3, the first plane 11 can contact the battery pack 2 to play a role in buffering. Since the second plane 12 is a guiding plane inclined in the front-rear direction of the vehicle, it can be inclined upward from front to back or inclined upward from front to back. When the front subframe 3 moves backward due to a collision, the front subframe 3 contacts the second plane 12 and moves along the guiding direction of the second plane 12, causing the front subframe 3 to be misaligned with the battery pack 2, avoiding the front subframe 3 from impacting the battery pack 2, so as to achieve the purpose of protecting the battery pack 2.

[0040] In one embodiment, the vehicle body assembly further includes a lower vehicle body, and the guiding structure 1 is fixed on the lower vehicle body.

[0041] As an example, the vehicle body assembly further includes a lower vehicle body. The battery pack 2, the front subframe 3, and the guiding structure 1 are assembled below the lower vehicle body. The guiding structure 1 can be fixedly installed below the lower vehicle body through fasteners. Specifically, two assembly holes can be provided on the guiding structure 1 along the left - right direction of the vehicle body, and fasteners (such as connecting bolts) are passed through the assembly holes to fix the guiding structure 1 below the lower vehicle body, preventing the failure phenomenon caused by the rotation of the guiding structure 1 itself during use.

[0042] In one embodiment, the number of the guiding structures 1 is at least two. The at least two guiding structures 1 are spaced apart along the left - right direction of the vehicle, and the guiding directions of the at least two guiding structures 1 are the same.

[0043] As an example, the vehicle body assembly includes at least two guiding structures 1. The at least two guiding structures 1 are both arranged between the battery pack 2 and the front subframe 3. The at least two guiding structures 1 are spaced apart in the left - right direction of the vehicle body, and the guiding directions of the at least two guiding structures 1 are the same. When the front subframe 3 is collided and moves backward, it can move along the same guiding direction, for example, move towards one end away from the lower vehicle body along the guiding direction. By arranging two guiding structures 1 separately in the left - right direction of the vehicle body, a more comprehensive protection can be formed for the rear battery pack 2, making the guiding effect more stable and reliable.

[0044] The embodiment of the present utility model also provides a vehicle, including the vehicle body assembly in any of the above - mentioned embodiments.

[0045] As an example, the vehicle includes the vehicle body assembly in any of the above - mentioned embodiments. In this example, by adding the guiding structure 1 between the front subframe 3 and the battery pack 2 of the vehicle, when the front subframe 3 is collided and moves backward, it can guide the front subframe 3 to move along the guiding direction of the second plane 12, dispersing the impact force generated by the front subframe 3 on the battery pack 2 and preventing excessive impact damage to the battery pack 2.

[0046] The above - described embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model, and should all be included within the protection scope of the present utility model.
