Will pop up.

(ECU22)
As shown in FIG. 1, the ECU 22 is provided in a dashboard (not shown) provided on the front side of the cabin 34. Further, the ECU 22 operates an actuator 18 and a subactuator 20 described later based on outputs from various sensors. Specifically, the ECU 22 receives a signal from a pressure sensor 40 that detects a pressure in a pressure chamber 38 disposed in the front bumper cover 36, and a vehicle speed sensor 42 that detects the speed of the vehicle 12. Signal is input. The vehicle speed signal input from the vehicle speed sensor 42 exceeds a predetermined value (exceeds a predetermined vehicle speed), and the value of the signal input from the pressure sensor 40 when the pedestrian P or the like collides with the front portion of the vehicle 12 is predetermined. The ECU 22 operates the actuator 18 and the subactuator 20 when there is a change in the above. In this embodiment, the actuator 18 and the sub-actuator 20 are set to operate simultaneously. However, the sub-actuator 20 may be set to operate after the actuator 18 is operated.

(Subactuator 20)
As shown in FIG. 3, the basic configuration of the subactuator 20 is the same as that of the actuator 18. The subactuator 20 includes a cylinder 50 and a rod 52 corresponding to the cylinder 44 and the rod 46 of the actuator 18.

  The lower end portion of the rod 52 is a piston portion 52 </ b> A having an outer diameter corresponding to the inner diameter of the cylinder 50. Further, a plurality of ratchet teeth 52B constituting a part of the locking device 54 are formed in a portion of the rod 52 above the piston portion 52A, and the plurality of ratchet teeth 52B extend along the longitudinal direction of the rod 52. Are arranged at regular intervals. Further, the ratchet teeth 52B are formed so as to gradually narrow toward the upper side. In order to make the configuration of the ratchet teeth 52B easy to understand, the size of the ratchet teeth 52B is exaggerated in FIG.

  Further, a C-ring 56 constituting another part of the lock device 54 is attached to the upper end portion of the cylinder 50. When the C-ring 56 is engaged with the ratchet teeth 52B, the rod 52 is extended from the cylinder 50, that is, the rod 52 extended from the cylinder 50 is held. It does not return into the cylinder 50. In this embodiment, when the operation of the pair of left and right actuators 18 and the subactuator 20 is completed, the upper end portion 52C of the rod 52 of the subactuator 20 is connected to the rear end portion 14 of the front hood 14 and both end portions A2 in the vehicle width direction. It is possible to extend upward (see FIG. 6). Furthermore, in this embodiment, the output of the subactuator 20 is set lower than the outputs of the pair of left and right actuators 18 that push up the rear end portion 14R of the front hood 14.

  As shown in FIG. 1, the sub-actuator 20 described above is mounted on the vehicle body in a state where it is disposed below the rear end portion 14 </ b> R of the front hood 14 and at a substantially central portion in the vehicle width direction of the pair of left and right actuators 18. It is fixed. When the front hood 14 is closed, the upper end portion 52C of the rod 52 of the subactuator 18 and the rear end portion 14R of the front hood 14 are separated from each other in terms of noise reduction.

(Operation and effect of this embodiment)
Next, the operation and effect of this embodiment will be described.

  As shown in FIG. 1, when a vehicle 12 equipped with the pop-up hood device 10 of the present embodiment is traveling, when the pedestrian P collides with the front portion of the vehicle 12, the collision is caused by the pressure chamber 38 and the pressure. Detected by sensor 40. As a result, the pair of left and right actuators 18 and the subactuator 20 are operated.

  As shown in FIG. 4, when the pair of left and right actuators 18 are actuated, the pair of actuators 18 are extended, and the actuator 18 pushes up the rear end portion 14 </ b> R of the front hood 14 toward the vehicle upper side. As a result, the rear end portion 14R of the front hood 14 moves to the vehicle upper side while being supported by the pair of left and right hood hinges 16 (see FIG. 2). That is, the rear end portion 14R of the front hood 14 pops up. In FIG. 4, the hood hinge 16 is not shown, and the relationship between the actuator 18 and the front hood 14 is shown in a simplified manner.

  As shown in FIGS. 4 to 6, when the subactuator 20 operates simultaneously with the operation of the pair of left and right actuators 18, the upper end portion 52 </ b> C of the rod 52 of the subactuator 20 becomes the rear end portion 14 </ b> R of the front hood 14. The vehicle moves upward while following the intermediate portion A1 in the vehicle width direction. Further, since the above-described locking device 54 is provided in the sub-actuator 20, an intermediate portion A1 in the vehicle width direction of the rear end portion 14R of the front hood 14 from the initial operation of the pair of left and right actuators 18 to the completion of the operation. Is displaced by the subactuator 20. Thereby, in this embodiment, it can suppress that the rear-end part 14R of the front hood 14 vibrates by using the pair of left and right hood hinges 16 as a fulcrum when the pop-up is completed.

  Incidentally, in the present embodiment, the output of the sub-actuator 20 is set lower than the outputs of the pair of left and right actuators 18 that push up the rear end portion 14R of the front hood 14. Therefore, when the pair of left and right actuators 18 are actuated and the pair of actuators 18 starts to push up the rear end portion 14R of the front hood 14, as shown in FIG. Both end portions A2 in the vehicle width direction rise earlier than the intermediate portion A1 in the vehicle width direction. That is, the rear end portion 14R of the front hood 14 is curved in a substantially U shape with the upper side opened in a front view. The intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14 rises later than the both end portions A2 in the vehicle width direction.

  Further, both end portions A2 in the vehicle width direction of the rear end portion 14R of the front hood 14 are supported by the hood hinges 16. Therefore, as shown in FIG. 6, the intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14 is positioned on the vehicle upper side from both end portions A2 in the vehicle width direction due to the inertia of the intermediate portion A1. It is possible to do. That is, it is conceivable that the rear end portion 14R of the front hood 14 is curved in a substantially U shape with the lower side opened in a front view. Even in this case, in the present embodiment, the upper end portion 52C of the rod 52 of the subactuator 20 can extend above the rear end portion 14 of the front hood 14 and both end portions A2 in the vehicle width direction. Therefore, the upper end portion 52C of the rod 52 of the subactuator 20 can follow the intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14. The pair of left and right actuators 18 and subactuators 20 are provided with the locking devices 48 and 54 described above. For this reason, the rear end portion 14R of the front hood 14 is held in a substantially U-shaped curved shape with the lower side opened in a front view, and the pop-up of the rear end portion 14R of the front hood 14 is completed. Thereby, in this embodiment, the shock absorption stroke of the intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14 can be increased. In addition, the contact area with the pedestrian P can be reduced, thereby reducing the initial reaction force when the pedestrian P contacts the rear end portion 14R of the front hood 14.

  In the present embodiment, the output of the subactuator 20 is set lower than the outputs of the pair of left and right actuators 18 that push up the rear end portion 14R of the front hood 14, thereby reducing the size of the subactuator 20 (particularly in the radial direction). ) And weight can be reduced.

  In the present embodiment, an example in which the upper end 52C of the rod 52 of the subactuator 20 can extend upward from the rear end 14 of the front hood 14 and both ends A2 in the vehicle width direction. However, the present invention is not limited to this. Whether or not the upper end portion 52C of the rod 52 of the subactuator 20 extends to the upper side of the rear end portion 14 of the front hood 14 and the both end portions A2 in the vehicle width direction is determined on the rear end portion 14R of the front hood 14. What is necessary is just to set suitably in consideration of rigidity etc.

  Moreover, although this embodiment demonstrated the example which comprised the pop-up hood apparatus 10 using the actuator 18 of the type from which the rod 46 extends with respect to the cylinder 44, this invention is not limited to this. For example, an actuator of a type that pushes up the rear end portion 14R of the front hood 14 by releasing a biased spring can be used.

  Further, in the present embodiment, the example in which the output of the sub-actuator 20 is set lower than the outputs of the pair of left and right actuators 18 that push up the rear end portion 14R of the front hood 14 has been described, but the present invention is not limited to this. . For example, the output of the subactuator 20 may be set to an output equivalent to that of the pair of left and right actuators 18. According to the said structure, the both ends A2 of the vehicle width direction in the rear-end part 14R of the front hood 14 and the intermediate part A1 of the vehicle width direction can be pushed up more uniformly. Further, the output of the subactuator 20 may be set to be higher than that of the pair of left and right actuators 18. According to the said structure, the intermediate part A1 of the vehicle width direction in the rear-end part 14R of the front hood 14 can be pushed up more rapidly compared with the both ends A2 of the vehicle width direction. That is, the rear end portion 14R of the front hood 14 can be pushed up in a state of being bent in a substantially U shape with the lower side opened in a front view. Thereby, the impact absorption stroke of the intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14 is increased, and the impact input to the pedestrian P can be further absorbed.

(Regulator according to the first modification)
Next, a regulating device 58 according to a first modification of the above embodiment will be described with reference to FIGS. 7 to 8B.

The other end (lower end) of the first link 60 is rotatably connected to a bracket 66 provided on the vehicle body via a pin P6. The other end portion (upper end portion) of the second link 62 is rotatably connected to an intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14 via a pin P7.

  As shown in FIGS. 8A and 8B, the upper end portion 60A of the first link 60 abuts the lower end portion 62A of the second link 62, so that the rotation range of the second link 62 relative to the first link 60 is increased. A restricting contact portion 60B is provided. A torsion spring 63 is interposed between the upper end portion 60 </ b> A of the first link 60 and the lower end portion 62 </ b> A of the second link 62. And the regulation state of the regulating device 58 described later is held by the elastic force of the torsion spring 63.

  As shown in FIG. 7, according to the restriction device 58 of this modification described above, when the pair of left and right actuators 18 (see FIG. 1) are operated, the first link 60 and the second link 62 of the restriction device 58 are The storage state indicated by the imaginary line (state indicated by reference numeral B1) changes to the restricted state indicated by the solid line (state indicated by reference numeral B2). Thereby, the displacement of the intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14 in the vehicle vertical direction is restricted by the restriction device 58. As a result, in this modification, it is possible to suppress the rear end portion 14R of the front hood 14 from vibrating about the pair of left and right hood hinges 16 (see FIG. 1) when the pop-up is completed. Moreover, in this modification, the cost of a pop-up hood apparatus can be reduced compared with the case where the pop-up hood apparatus 10 is comprised using the subactuator 20 of the said embodiment.

The first rod 72 and the second rod 74 are pulled out from the cylinder 70 by pulling the second rod 74 toward the vehicle upper side via the wire 76. The restriction device 68 includes a locking device (not shown), so that the first rod 72 and the second rod 74 drawn from the cylinder 70 do not return into the cylinder 70. Further, the length of the wire 76 is set so that the wire 76 is loosened in a state where the front hood 14 is closed (a state indicated by an imaginary line). As described above, since the wire 76 is set to be loosened, the high installation accuracy of the regulating device 68 on the vehicle body is not required.

  According to the restriction device 68 of the present modification described above, when the pair of left and right actuators 18 (see FIG. 1) are operated, the first rod 72 and the second rod 74 of the restriction device 68 are pulled out of the cylinder 70 and locked. (The regulating device extends and locks from the state indicated by the imaginary line to the state indicated by the phantom line). Accordingly, the displacement of the intermediate portion A1 in the vehicle width direction at the rear end portion 14R of the front hood 14 to the vehicle upper side is restricted by the restriction device 68.
