Description

[Technical field]

[0001] The present invention relates to a hood lock striker in a mechanism for locking a hood of an engine compartment to a vehicle body. [Background technology]

[0002] In a vehicle, the drive source, such as an internal combustion engine like a gasoline engine or an electric motor, is usually housed in an engine compartment located at the front, and a hood is provided on the engine compartment as a lid that can be opened and closed on the top surface.

[0003] The rear end of the hood is supported by a hinge or the like on the passenger compartment side of the engine room, and the front end can be lifted upward. This front end can be locked to the vehicle body side by a hood lock mechanism.

[0004] The hood lock mechanism has a square frame-shaped hood lock striker provided on the hood side, which is locked by engaging with a latch on the vehicle body side.

[0005] In Patent Document 1, a hood lock striker is fixed to the back side of the hood via a reinforcing plate, and engagement pieces that suppress movement of the reinforcing plate are provided on the hood around the periphery of the reinforcing plate, thereby suppressing movement of the hood lock striker. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2012-30641 A Summary of the Invention [Problem to be solved by the invention]

[0007] Here, there are cases where it is desirable to adjust the amount of protrusion of the hood lock striker from the back side of the hood. That is, the amount of protrusion of the hood lock striker is adjusted in correspondence with the latch so that the hood lock striker can be securely locked when it is locked to the latch on the vehicle side and no rattling occurs after locking.

[0008] In this case, it is conceivable to make the hood lock striker adjustable by using a screw mechanism or the like. However, when a screw mechanism is used, some rattle occurs in the screw mechanism. If the hood is open and the hood swings sideways due to opening and closing the door, an abnormal rattling noise may be generated from the hood lock striker.

[0009] The present invention suppresses the generation of abnormal noise from the hood lock striker. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment described herein.

[0015] "Hood configuration" FIG. 1 is a schematic perspective view showing a state in which the hood at the front of the vehicle is open. An engine room 12 is provided at the front of a vehicle body 10. The engine room 12 houses a power source such as a gasoline engine or an electric motor, and various other devices. A hood 14 is provided as a lid for the engine room 12. The hood 14 is a rectangular plate, and is supported by the vehicle body 10 by a pair of hinges 16 provided on both the left and right sides of the rear. Therefore, the hood 14 opens and closes by rotating its front end with the hinge 16 at the rear as a fulcrum. In this example, the hood 14 faces almost horizontally when closed, and rises forward at about 40-60 degrees when open.

[0016] Latches 18 are provided at two locations, one on the left and one on the upper front end of the engine compartment 12, and hood lock strikers 20 are provided at positions (two locations, one on the left and one on the lower front end) of the hood 14 corresponding to the latches 18. When the hood 14 is closed, the hood lock strikers 20 engage with the latches 18, and the hood 14 is locked to the vehicle body 10.

[0017] "Configuration of the Hood Lock Striker" 2 is an enlarged perspective view of the hood lock striker 20 from the rear side of the A portion of FIG. 1, and FIG. 3 is a cross-sectional view taken along line XX of FIG.

[0018] First, the external configuration will be described with reference to Fig. 2. The hood 14 has a structure in which, for example, two plates (usually steel plates) are overlapped, and an inner panel 14a is provided on the back side. Although only the inner panel 14a is shown in Figs. 2 and 3, an outer panel is provided above the inner panel 14a, forming the upper surface of the hood 14.

[0019] The hood lock striker 20 is provided at a predetermined portion (the lower left and right portions of the front portion corresponding to the latch 18) of the inner panel 14a. The hood lock striker 20 has a base plate 30 that is generally triangular, and three corners of the base plate 30 are fixed to the inner panel 14a by bolts 32. The base plate 30 has one side located on the front side and one apex located on the rear side. A nut 36 is attached to the middle portion of the one front side side of the base plate 30, and this nut 36 protrudes from the base plate 30 to the back side. A bolt 38 is screwed to the back side end of the nut 36, and this bolt 38 further extends in a direction away from the inner panel 14a (to the back side). One end of an L-shaped shaft 40 is fixed to the tip of the bolt 38 on the opposite side to the nut 36, and the other end of this shaft 40 bends at a right angle and then extends toward the base plate 30 and penetrates it. In addition, a spring 50 is disposed between the nut 36 and the bolt 38. Each component of the hood lock striker 20 is generally made of steel.

[0020] The configuration of the hood lock striker 20 will be described with reference to Fig. 3. The base plate 30 is fixed to the inner panel 14a by bolts 32, which are located on the back side of the hood 14 and are screwed into nuts 34 arranged inside the hood 14 (below the outer panel), thereby tightening and fixing the base plate 30 and the inner panel 14a. The bolts 32 and nuts 34 are provided at the three vertices of the base plate 30. In this example, a triangular frame-shaped reinforcing plate 28 is interposed in the portion where the base plate 30 and the inner panel 14a contact each other, and the reinforcing plate 28 is also fixed together.

[0021] The base plate 30 has a mounting hole 30a in the middle of one side on the front side thereof, and one end (upper end) of a nut 36 is attached to this mounting hole. The nut 36 has two flange portions 36a, 36b that extend outward at the upper end, and the periphery of the mounting hole 30a of the base plate 30 is inserted into an annular recess between the two flange portions 36a, 36b, and the nut 36 is fixed to the base plate 30. The flange portion on the tip (upper end) side may be formed by welding or the like after the base plate 30 is inserted, or a recess may be formed first, and the base plate 30 may be inserted into this recess and fixed with an adhesive or the like or by screws.

[0022] The nut 36 has a body 36c extending in a direction (downward) away from the base plate 30. The body 36c is hollow and cylindrical with a threaded inner surface. A threaded portion 38a provided on one end (upper side) of a bolt 38 is screwed into the body 36c of the nut 36.

[0023] The bolt 38 has two flanges 38b, 38c at the other end, and the lateral end of the shaft 40 is inserted together with the washer 42 into the annular recess between the two flanges. That is, a hole 40a through which the bolt 38 is inserted is formed at the lateral end (one end) of the shaft 40, and the periphery of the hole 40a is located in the recess between the flanges 38b, 38c. The washer 42 is a spring washer, and presses the end of the shaft 40 against the flanges in the recess, but allows the bolt 38 to rotate. The flanges on the end side of the bolt 38 can be formed by various means in the same manner as the flanges of the nut 36, and can be, for example, a nut screwed onto the bolt 38.

[0024] The shaft 40 is an L-shaped cylinder as a whole, and the portion inserted into the recess of the bolt 38 is thin and flat. Then, after extending from one end inserted into the recess of the bolt 38 in a direction parallel to the hood 14, it bends at a right angle, faces the base plate 30, penetrates the hole 30b of the base plate 30, and extends into the inside of the hood 14. Note that the shaft 40 advances and retreats without any gap between the base plate 30 and the shaft 40 at the penetration portion. A resin or metal bushing material may be placed in the hole 30b to make it difficult for a gap to occur. Here, the shaft 40 functions as a lock striker main body that engages with the latch.

[0025] Because the bolt 38 is screwed into the nut 36, when the bolt 38 is rotated, it moves in the axial direction relative to the nut 36, which causes the shaft 40 to move relative to the base plate 30. Therefore, the position of the shaft 40 relative to the base plate 30 can be adjusted by adjusting the rotation of the bolt 38. During assembly of the vehicle in the factory, the position of the shaft 40 can be adjusted to an optimal position in relation to the latch 18.

[0026] In this embodiment, a spring 50 is disposed between the end of the body portion 36c on the rear surface protruding side of the nut 36 and the flange portion 38b of the bolt on the base plate 30 side. This applies a force to the bolt 38 in a direction away from the nut 36. In addition, a force is applied to the shaft 40 connected to the bolt 38 in a direction away from the base plate 30. Therefore, a force is applied between the shaft 40 and the base plate 30, suppressing rattling.

[0027] In this embodiment, a compression coil spring is used as the spring 50. A compression coil spring can be arranged to surround the bolt 38, and can provide a reliable axial biasing force, making it the most efficient configuration. However, a leaf spring or the like can also be used. In this example, the head 38d of the bolt 38 is hexagonal, and can be easily rotated with a wrench or the like. A driver groove may be formed in the head (lower surface) 38d of the bolt 38 to make it easier to rotate with a driver. [Explanation of symbols]
