[0034] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.
[0035] like Figures 1 to 8 As shown, the forward nacelle reinforcement structure 10 of this embodiment includes an outer plate 1 and an inner plate 2 extending in the front-rear direction. The outer plate 1 and the inner plate 2 are connected and form a cavity 3. The forward nacelle reinforcement structure 10 is provided with an energy-absorbing area 101, which is used to deform when the forward nacelle reinforcement structure 10 is involved in a collision.
[0036] The front engine compartment reinforcement structure 10 of this embodiment incorporates an energy-absorbing zone 101. Upon collision, the energy-absorbing zone 101 deforms to absorb energy generated during the collision, thus reducing the amount of energy transferred to the passenger compartment and improving the safety of vehicles equipped with this front engine compartment reinforcement structure 10. Consequently, the front engine compartment reinforcement structure 10 can be constructed using lower-weight and thinner materials, reducing its cost and weight.
[0037] In some embodiments, such as Figures 2 to 7 As shown, the outer panel 1 has a bending portion 11 in the energy absorption area 101, and the bending portion 11 is used to deform when the front cabin reinforcement structure 10 is involved in a collision.
[0038] By providing a bending portion 11 in the energy absorption zone 101, the energy absorption zone 101 is made to deform easily when subjected to force. As a result, when the front engine compartment reinforcement structure 10 is involved in a collision, it is easier to absorb the energy generated during the collision process by deforming the energy absorption zone 101, thereby further improving the safety of the vehicle with the front engine compartment reinforcement structure 10.
[0039] Optionally, such as Figures 3 to 5 As shown, the bent portion 11 extends in the vertical direction. The cross-section of the bent portion 11 cut by the first preset plane is U-shaped, and the first preset plane is perpendicular to the vertical direction.
[0040] By setting the cross-section of the bending part 11 to U-shape, the processing and manufacturing of the bending part 11 is facilitated, which helps to reduce the cost of the front cabin reinforcement structure 10.
[0041] Optionally, such as Figure 2 and Figure 3 As shown, there are multiple bends 11, and the multiple bends 11 are arranged at intervals along the front-back direction.
[0042] By setting multiple bends 11, the energy absorption zone 101 has more parts that can deform when subjected to force, thereby absorbing more energy generated during the collision process through the deformation of the energy absorption zone 101, further improving the safety of the vehicle with the front engine compartment reinforcement structure 10.
[0043] Optionally, such as Figures 2 to 4 As shown, at least one bent portion 11 is a protrusion 111, which protrudes outward. At least two bent portions 11 are recessed portions 112, which are recessed inward. There is at least one protrusion 111 between two adjacent recessed portions 112.
[0044] The protrusion 111 can induce the outer plate 1 to deform into the cavity 3, and the recess 112 can induce the outer plate 1 to deform outward from the cavity 3.
[0045] For example, such as Figures 2 to 4 As shown, there is one protrusion 111 and two recesses 112, with the protrusion 111 positioned between the two recesses 112. Figure 6 and Figure 7 As shown, when the forward cabin reinforcement structure 10 collides, the energy absorption zone 101 transmits force along a "Z"-shaped path. Figure 6 (in the direction of the middle arrow), causing the energy absorption region 101 to deform into a "Z" shape.
[0046] By setting the energy-absorbing zone 101 to the above structure, more energy generated during the collision process can be absorbed through the deformation of the energy-absorbing zone 101, greatly reducing the deformation of the passenger compartment and further improving the safety of the vehicle with the front engine compartment reinforcement structure 10.
[0047] Optionally, the height of the protrusion 111 is 4mm to 8mm.
[0048] For example, the height of the protrusion 111 is 6mm.
[0049] By setting the height of the protrusion 111 to 4mm to 8mm, the outer panel 1 can be better induced to deform into the cavity 3, thereby further improving the safety of the vehicle with the front engine compartment reinforcement structure 10.
[0050] Optionally, the depth of the recess 112 is 4 mm to 8 mm.
[0051] For example, the depth of the recess 112 is 6 mm.
[0052] By setting the depth of the recess 112 to 4mm to 8mm, the outer panel 1 can be better induced to bulge outward from the cavity 3, thereby further improving the safety of the vehicle with the front engine compartment reinforcement structure 10.
[0053] In some embodiments, such as Figure 1 , Figure 3 , Figures 5 to 7 As shown, the forward nacelle reinforcement structure 10 has a reinforcement zone 102, which is located on the front side of the energy absorption zone 101, and the reinforcement zone 102 has a reinforcement plate 4.
[0054] By providing a reinforcing zone 102 on the front side of the energy-absorbing zone 101, and installing a reinforcing plate 4 in the reinforcing zone 102, the structural strength of the reinforcing zone 102 can be improved. Therefore, in the event of a collision, the reinforcing zone 102 optimizes the force transmission channel of the front engine compartment reinforcing structure 10, improves the load-bearing capacity of the reinforcing zone 102, prevents deformation of the passenger compartment during a collision, and further enhances the safety of vehicles equipped with this front engine compartment reinforcing structure 10.
[0055] Optionally, such as Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the reinforcing plate 4 is located inside the cavity 3 and extends in the front-to-back direction. Both the outer plate 1 and the inner plate 2 are connected to the reinforcing plate 4.
[0056] By placing the reinforcing plate 4 inside the cavity 3, and connecting both the outer plate 1 and the inner plate 2 to the reinforcing plate 4, the structural strength of the reinforcing area 102 is effectively improved, effectively preventing deformation of the passenger compartment during a collision, and further improving the safety of vehicles with this front engine compartment reinforcing structure 10.
[0057] Optionally, such as Figure 8As shown, the reinforcement plate 4 includes a first fixing part 41, a first connecting part 42, a second fixing part 43, a second connecting part 44, and a third fixing part 45 connected in sequence. Both the first fixing part 41 and the third fixing part 45 are connected to the outer plate 1, and the second fixing part 43 is connected to the inner plate 2.
[0058] Among them, the first fixing part 41 and the third fixing part 45 can be welded to the outer plate 1, and the second fixing part 43 is welded to the inner plate 2.
[0059] By setting the reinforcement plate 4 to the above structure, the bearing capacity of the reinforcement area 102 can be effectively improved, effectively avoiding deformation of the passenger compartment during a collision, and further improving the safety of the vehicle with the front engine compartment reinforcement structure 10.
[0060] Optionally, as Figure 8 shown, the cross-section of the reinforcement plate 4 intercepted by the second preset plane is in a U-shaped, and the second preset plane is parallel to the up-down direction.
[0061] By setting the reinforcement plate 4 to the above structure, while the structural strength of the reinforcement area 102 is good, the structure of the reinforcement plate 4 can be simplified, facilitating the front engine compartment reinforcement structure 10 and reducing the cost of the front engine compartment reinforcement structure 10.
[0062] Optionally, the ratio of the dimension of the energy absorption area 101 in the front-back direction to the dimension of the front engine compartment reinforcement structure 10 in the front-back direction is 0.15 - 0.35.
[0063] For example, as Figure 1 shown, the dimension of the energy absorption area 101 in the front-back direction is L1, the dimension of the reinforcement area 102 in the front-back direction is L2, and the dimension of the front engine compartment reinforcement structure 10 in the front-back direction is the sum of L1 and L2. L1 / (L1 + L2) is 0.15 - 0.35, where L1 / (L1 + L2) can be 0.3.
[0064] By setting the ratio of the dimension of the energy absorption area 101 in the front-back direction to the dimension of the front engine compartment reinforcement structure 10 in the front-back direction to 0.15 - 0.35, the energy generated during the collision can be effectively absorbed, and the safety of the vehicle with the front engine compartment reinforcement structure 10 can be further improved.
[0065] Optionally, the ratio of the dimension of the reinforcement area 102 in the front-back direction to the dimension of the front engine compartment reinforcement structure 10 in the front-back direction is 0.65 - 0.85.
[0066] For example, as Figure 1As shown, the size of the energy absorption area 101 in the front-back direction is L1, the size of the reinforcement area 102 in the front-back direction is L2, and the size of the front engine compartment reinforcement structure 10 in the front-back direction is the sum of L1 and L2. L2 / (L1 + L2) is 0.65 to 0.85, and among them, L2 / (L1 + L2) can be 0.7.
[0067] By setting the ratio of the size of the reinforcement area 102 in the front-back direction to the size of the front engine compartment reinforcement structure 10 in the front-back direction to be 0.65 to 0.85, the bearing capacity of the reinforcement area 102 can be effectively improved, and further the safety of the vehicle with the front engine compartment reinforcement structure 10 can be improved.
[0068] The assembly method of the front engine compartment reinforcement structure 10 of the present disclosure embodiment: First, weld and assemble the outer plate 1 and the reinforcement plate 4 into a total assembly, and then weld the total assembly and the inner plate 2 to assemble the front engine compartment reinforcement structure 10.
[0069] The cross-section of the reinforcement area 102 is in the shape of a Chinese character 'Mu'. The use of the reinforcement plate 4 improves the structural strength of the reinforcement area 102, enabling the bearing capacity of the reinforcement area 102 to be doubled, and improving the safety of the vehicle with the front engine compartment reinforcement structure 10. The energy absorption area 101 is provided with a plurality of bending portions 11, so that when the front engine compartment reinforcement structure 10 collides, the energy absorption area 101 is deformed to absorb the energy generated during the collision process, and the safety of the vehicle with the front engine compartment reinforcement structure 10 is improved.
[0070] Compared with the front engine compartment reinforcement structure in the related technology, the weight of the front engine compartment reinforcement structure 10 of the present disclosure embodiment can be reduced by about 10%, the cost can be reduced by about 7%, the bearing capacity can be doubled or more, greatly reducing the deformation of the passenger compartment, ensuring the safety space of the passengers, and effectively improving the collision ability of the vehicle with the front engine compartment reinforcement structure 10.

[0072] The vehicle of the present disclosure embodiment includes the front engine compartment described in any one of the above embodiments.
