[0028] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.
[0029] This embodiment provides a front engine compartment cover assembly.
[0030] Combination Figures 1 to 5 As shown, the front engine cover assembly includes an engine cover 1 and an engine cover 2. The engine cover 1 includes a middle area and an edge area arranged around the middle area. The engine cover 1 in the middle area is protruded relative to the engine cover 1 in the edge area. The engine cover 2 is arranged on the engine cover 1, and a collapse cavity 101 is formed between the engine cover 1 in the edge area. In this embodiment, when a vehicle collides with a pedestrian, the first level of energy absorption can be generated by the gap of the collapse cavity 101 formed between the engine cover 2 and the engine cover 1 in the edge area to protect the pedestrian.
[0031] Furthermore, the front engine cover assembly also includes a buffer block, and the engine cover inner cover 1 in the edge area is provided with a buffer block mounting hole 102, and the buffer block is installed in the buffer block mounting hole 102 to play a second-level energy absorption role when the engine cover inner cover 1 and the engine cover outer cover 2 are crushed and deformed.
[0032] Furthermore, the front engine cover assembly further comprises a support structure 3, which is located in the collapse cavity 101 and is arranged adjacent to the buffer block mounting hole 102; one end of the support structure 3 is connected to the engine cover inner 1, and the other end of the support structure 3 is connected to the engine cover outer 2. In this embodiment, the support structure 3 is arranged adjacent to the buffer block mounting hole 102, which means that the support structure 3 is in contact with the buffer block mounted in the buffer block mounting hole 102 along the length direction or width direction of the front engine cover assembly, or the distance between them is less than 20 cm.
[0033] It should be understood that the cabin inner cover 1 is provided with a buffer block mounting hole 102, and after the buffer block is installed in the buffer block mounting hole 102, the position of the cabin inner cover 1 where the buffer block is provided can play an energy absorption role, but the rigidity of the area is also weakened. Therefore, a support structure 3 is provided at a position adjacent to the buffer block mounting hole 102, one end of the support structure 3 is connected to the cabin inner cover 1, and the other end of the support structure 3 is connected to the cabin outer cover 2, so as to support the collapse cavity 101 between the cabin inner cover 1 and the cabin outer cover 2, so as to balance the buffer energy absorption and rigidity of the cabin inner cover 1.
[0034] In this process, by setting the support structure 3 at the position close to the buffer block mounting hole 102, the rigidity gain of the engine cover assembly can be large and the loss of insurance points can be small. Ultimately, the rigidity gain of the engine cover assembly is increased with a small loss of insurance points, and a large-size engine cover design with higher requirements can be achieved at a lower cost.
[0035] Furthermore, combined with Figure 3 As shown, the support structure 3 includes a top plate 31, a bottom plate 32 and an intermediate connecting plate 33. The intermediate connecting plate 33 is connected between the top plate 31 and the bottom plate 32 to form a "Z"-shaped structure. The bottom plate 32 is connected to the cabin inner cover 1, and the top plate 31 is connected to the cabin outer cover 2. In this embodiment, the support structure 3 in a "Z"-shaped structure can better balance the buffering energy absorption and rigidity of the cabin inner cover 1 after being subjected to force compared to structures of other shapes. Of course, in other embodiments, the support structure 3 can also be a "U"-shaped or other structure.
[0036] It should be understood that the "Z"-shaped structure is not a "Z"-shaped structure in the strict sense, as long as the outline is approximately in the "Z" shape.
[0037] Furthermore, the area of the top plate 31 is smaller than that of the bottom plate 32 , which can save materials.
[0038] Furthermore, the support structure 3 further includes a reinforcing rib 34, which is disposed on the middle connecting plate 33 and extends from the top plate 31 toward the bottom plate 32. In this embodiment, the length direction of the reinforcing rib 34 is the same as the length direction of the middle connecting plate 33, and is used to enhance the supporting effect of the middle connecting plate 33.
[0039] Furthermore, the support structure 3 further includes an expansion glue 8, and the top plate 31 is provided with a glue groove 103. The expansion glue 8 is arranged in the glue groove 103 and is used to connect the top plate 31 with the cabin cover 2. In this embodiment, the support structure 3 is in contact with the cabin cover 2 through the expansion glue 8, which can improve the mode of the cabin cover assembly compared with the direct contact between the support structure 3 and the cabin cover 2.
[0040] Furthermore, the cabin cover 1 includes a left side 1a and a right side 1b that are relatively arranged, and a front side 1c and a rear side 1d that are relatively arranged. The rear side 1d of the cabin cover 1 is used to be hinged with the vehicle body. The left side 1a and the right side 1b of the cabin cover 1 are both provided with a buffer block mounting hole 102. The front cabin cover assembly includes two support structures 3, and the two support structures 3 are arranged one by one on the left side 1a and the right side 1b of the cabin cover 1, and are both arranged adjacent to the buffer block mounting hole 102. In this embodiment, there are multiple buffer block mounting holes 102, and each of them is installed with a buffer block. Among them, when the cabin cover assembly is installed on the vehicle body, the two support structures 3 are adjacent to the buffer block mounting hole 102 located closest to the midpoint of the cabin cover 1 along the wheelbase direction of the vehicle body. At this time, the buffering energy absorption and rigidity of the cabin cover 1 can be better balanced.
[0041] Furthermore, combined with Figure 2 and Figure 5 As shown, the front engine cover assembly also includes a front reinforcement 4, which is located in the collapse cavity 101 and is arranged on the front side 1c of the engine cover 1. The front reinforcement 4 is arranged corresponding to the middle area of the two support structures 3.
[0042] Furthermore, one end of the front reinforcement 4 is connected to the cabin inner cover 1, and the other end of the front reinforcement 4 is connected to the cabin outer cover 2 through the expansion glue 8, which can improve the mode of the cabin cover assembly compared to the direct contact between the front reinforcement 4 and the cabin outer cover 2. In this embodiment, a plurality of collapse holes 104 are provided on the front reinforcement 4 to balance the buffering energy absorption and rigidity of the front reinforcement 4.
[0043] Furthermore, the front engine cover assembly further includes a left hinge mounting plate 5 and a right hinge mounting plate 6, both of which are located in the collapse cavity 101. The left hinge mounting plate 5 is disposed on the left side 1a of the engine cover 1 and is close to the rear side 1d of the engine cover 1; the right hinge mounting plate 6 is disposed on the right side 1b of the engine cover 1 and is close to the rear side 1d of the engine cover 1. In this embodiment, the left hinge mounting plate 5 and the right hinge mounting plate 6 are used to be hinged to the vehicle body.
[0044] Furthermore, the front engine cover assembly also includes a rear reinforcement 7 provided with a plurality of collapse holes 104, and the rear reinforcement 7 is located at the rear side 1d of the engine room inner cover 1 and between the left hinge mounting plate 5 and the right hinge mounting plate 6; wherein, one end of the rear reinforcement 7 is connected to the engine room inner cover 1, and the other end of the rear reinforcement 7 is connected to the engine room outer cover 2, so as to support the engine room outer cover 2, and can play a role in buffering and absorbing energy while ensuring the rigidity of the front engine cover assembly.
[0045] Furthermore, the cabin inner cover 1 in the middle region is provided with a plurality of collapse holes 104, and the plurality of collapse holes 104 all penetrate the cabin inner cover 1, and the plurality of collapse holes 104 are arranged in an array to balance the buffering energy absorption and rigidity of the cabin inner cover 1 in the middle region.
