Description

The technologies disclosed herein relate to vehicles. Patent Document 1 discloses a vehicle comprising: a vehicle body with a front compartment; a hood for opening and closing the front compartment; a radiator positioned in the front compartment; a radiator support extending laterally along the upper edge of the radiator; and a hood lock for locking the hood in a position where the front compartment is closed. Japanese Patent Publication No. 2002-160667 This shows a side view of the front of the vehicle 100 of the embodiment.A perspective view of the area around the hood lock 20 is shown.Figure 2 shows a cross-sectional view along line III-III.This figure shows a cross-sectional view similar to that in Figure 3, when a collision test is performed on the vehicle 100 of the embodiment. In one embodiment of this technology, the hood lock may be fixed to the rear surface of the radiator support upper via a bracket plate. With this configuration, when a load is applied to the hood lock in a direction inclined toward the rear of the vehicle relative to the downward direction, the bracket plate of the hood lock is more likely to detach from the rear surface of the radiator support upper. As a result, the impact reaction force measured by the test equipment can be further reduced. In one embodiment of this technology, the bracket plate may have a main body extending vertically and a pair of extending portions extending forward from the main body on both sides of the hood lock in the left-right direction. In this case, the pair of extending portions may be fixed to the upper surface of the radiator support upper. When the hood moves to the closed position, a load is applied to the hood lock from above. With this configuration, the pair of extending portions transmit the load when the hood is closed to the upper surface of the radiator support upper. As a result, the durability against the load when the hood is closed can be improved. In one embodiment of this technology, the main body of the bracket plate has a first region fixed to the rear surface of the radiator support upper, a second region located above the first region and to which the hood lock is fixed, and an inclined portion interposed between the first and second regions. The inclined portion is displaced forward toward the second region so that the second region is located above the radiator support upper, and the pair of extending portions may extend from the second region to the upper surface of the radiator support upper. With this configuration, the inclined portion transmits the load when the hood is closed to the upper surface of the radiator support upper. As a result, the durability against the load when the hood is closed can be improved. In one embodiment of this technology, the radiator support upper may include a first member having a hat-shaped cross-section with an open bottom, and a second member that closes the hat-shaped cross-section from below the first member. With this configuration, the radiator support upper has a closed cross-sectional shape. As a result, the rigidity of the radiator port upper can be improved, and its durability against load when the hood is closed can be enhanced. (Examples) Figure 1 shows a front side view of the vehicle 100 of the embodiment. The vehicle 100 comprises a body 2, front wheels 5, a radiator 6, a hood 10, and a hood lock module 20. The vehicle 100 is, for example, an electric vehicle. In the coordinate system of Figure 1, "FR" indicates the forward direction of the vehicle. "UP" indicates the upward direction of the vehicle. "LH" indicates "left" when viewed from the rear to the front of the vehicle. The meaning of the coordinate system is the same in subsequent figures. A front compartment 4 is provided at the front of the vehicle body 2. The front compartment 4 is a space for housing various equipment of the vehicle 100. A hood 10 is positioned above the front compartment 4. The hood 10 is pivotably connected to the vehicle body 2 around a hinge 9 in the direction indicated by arrow S1. Therefore, the hood 10 can move between an open position L1 and a closed position L2. When the hood 10 is in the open position L1, the area above the front compartment 4 is open. When the hood 10 is in the closed position L2, the area above the front compartment 4 is closed. In this embodiment, the front compartment 4 of the vehicle 100 houses, for example, a radiator 6 and a hood lock module 20. The radiator 6 is a device for cooling, for example, the vehicle 100's drive motor and power converter (both not shown). The radiator 6 is fixed within the front compartment 4 by a radiator support upper 8. The radiator support upper 8 is a member that extends horizontally within the front compartment 4 (i.e., from front to back in Figure 1). Both ends of the radiator support upper 8 in the horizontal direction are connected to the side walls of the front compartment 4 (i.e., the vehicle body 2). That is, the radiator s
