AI Technical Summary
In the prior art, the engine hood assembly of a vehicle often requires a large space when closed, resulting in a reduction in the volume of the front trunk and high structural complexity. Especially in electric vehicles where there is no engine compartment, the design of the engine hood assembly is difficult to meet the requirements of space utilization and structural simplification.
The engine hood assembly adopts a channelless design, transitioning directly from the dome area to the waterfall area. This eliminates the traditional palm pad structure and uses a combination of impact pin reinforcements and adhesive for fixation, achieving a direct connection between the inside and outside of the engine hood, enhancing structural strength and reducing complexity.
It increases the volume of the front trunk, simplifies the structural design, reduces the complexity of parts, and does not affect the aesthetics, making it suitable for engine hood assemblies in electric vehicles.

[0027] Figure 6 It shows in Figure 4 A cross-sectional view of the engine hood assembly taken at line 6–6 in the figure. Detailed Implementation
[0028] This disclosure describes in detail a hood assembly that can be used to surround, for example, a front trunk or engine compartment. The hood assembly extends directly from the dome region into a waterfall region without any passageways in between. The hood assembly of the example in this disclosure also does not incorporate palm rest supports in front of the dome region, a characteristic of prior art hood assemblies.
[0029] refer to Figure 1 and Figure 2 The vehicle includes an engine hood assembly 14 pivotally fixed to the vehicle frame 18. When the engine hood assembly 14 is in... Figure 1 When the hood assembly is in the open position, the user can access the front trunk 22 of vehicle 10. The hood assembly 14 can be moved to... Figure 2 The hood assembly 14 is positioned to surround the front trunk 22. It is used in conjunction with the front trunk 22, but in other examples may also be used with conventional vehicles having an engine compartment.
[0030] Vehicle 10 is an electric vehicle, and more specifically, a fully electric vehicle that does not rely on an internal combustion engine for propulsion. Therefore, vehicle 10 does not include an engine or engine compartment. The space typically reserved for the engine can be used as a front trunk 22 in vehicle 10.
[0031] Now for reference Figure 3 and Figure 4 And continue to refer to Figure 1 and Figure 2 The engine hood assembly 14 includes an inner engine hood 26 and an outer engine hood 28. When the engine hood assembly 14 is in... Figure 2 When in the closed position, the exterior hood 28 is visible. The exterior hood 28 supports the grille 32 of the vehicle 10. The grille 32 may be functional and include openings that allow airflow. Alternatively, the grille 32 may be an aesthetic grille without such openings. In other examples, the grille 32 is omitted, and the exterior hood 28 supports another feature (e.g., a trim panel).
[0032] The grille 32 is positioned vertically above the bumper 36 of the vehicle 10 and horizontally between the headlights 38 of the vehicle 10. For the purposes of this disclosure, "vertical" and "horizontal" refer to the ground in the general orientation of the vehicle 10 during typical operation.
[0033] In this example, the interior of the hood 26 includes a waterfall region 42, a dome region 44, and a pair of hinge reinforcements 46. When the hood assembly 14 is in the closed position, the waterfall region 42 cascades down from the dome region 44.
[0034] The dome region 44 is a raised area inside the engine hood 26. An example dome region includes multiple holes 48.
[0035] The dome region 44 transitions directly into the waterfall region 42 inside the hood 26 without any intermediate structure. In the past, components such as palm rests have been used in the area in front of the dome region inside the hood to reinforce the hood assembly. Example hood assembly 14 transitions directly from the dome region 44 to the waterfall region 42 without any intermediate palm rests. In some examples, the dome region 44 can be considered a “power” dome.
[0036] It also occurs that the waterfall region 42 extends directly from the dome region 44 without incorporating any intermediate channel formation within the engine hood interior 26. Therefore, any region between the waterfall region 42 and the dome region 44 can be considered non-channelized.
[0037] This direct transition (without a passageway or palm rest) facilitates an increase in the volume of the front trunk 22. In this example, the total volume of the front trunk 22 is at least three liters larger than the hood interior used with palm rests.
[0038] Latch assembly 50 is used to secure example engine hood assembly 14 in Figure 2 The latch assembly 50 includes a reinforcing member, in this case, a striker reinforcement 54 fixed to the waterfall region 42. The waterfall region 42 and the striker reinforcement 54 face forward from the vehicle 10.
[0039] The ramming pin reinforcement 54 can be secured using rivets, welds, or some other attachment mechanism. When the hood assembly 14 is in the closed position, the waterfall area 42 is horizontally positioned between the headlights 38 and directly above the bumper 36. The ramming pin reinforcement 54 is also positioned between the headlights 38.
[0040] refer to Figure 5 and Figure 6 The cross-sectional view, and continue to refer to Figure 3 and Figure 4 The hood interior 26 is secured to the hood exterior 28 around at least a portion of the perimeter of the hood assembly 14 using a crimped joint. In this example, the securing strategy further includes an adhesive bond 58 that directly secures the dome region 44 of the hood interior 26 to the hood exterior 28. In some examples, putty adhesive is used to provide the adhesive bond.
[0041] The disclosed examples feature an engine hood interior that meets load targets without using a palm rest or channel between the dome-shaped and waterfall-shaped areas. This, in particular, facilitates reduced part complexity without allowing for dents.
[0042] The foregoing description is exemplary in nature and not restrictive. Variations and modifications made to the disclosed examples will become apparent to those skilled in the art, and such variations and modifications do not necessarily depart from the spirit of this disclosure. Therefore, the scope of protection accorded to this disclosure can only be determined by examining the appended claims.
