JP 2019-108710 A

In the above conventional technology, when the hood is fully closed, the coil spring rotates the safety lever to the restrained position, and the striker is restrained by the entrance groove of the base plate, thereby locking the hood to the vehicle body. By the way, in a structure in which the safety lever, which is an operation lever, is rotatably supported on the base plate by caulking, the safety lever has play, so even when the hood is locked to the vehicle body, the safety lever does not move. Rattling is likely to occur.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle hood lock structure capable of suppressing rattling of an operation lever when the hood is locked with respect to the vehicle body.

One aspect of the present invention is a vehicle hood lock structure that locks a hood with respect to a vehicle body when the hood provided on the vehicle is in a fully closed state. an operating lever supported by the body and pivoting between a first position for locking the hood with respect to the vehicle body and a second position for unlocking the hood with respect to the vehicle body; and an operating lever rotated from the second position to the first position. The base plate and the operating lever are arranged in the longitudinal direction of the vehicle body, and one of the base plate and the operating lever is in the first position. In the above, a contact portion is provided that contacts the other of the base plate and the operating lever, and the contact portion does not contact the other of the base plate and the operating lever when the operating lever is in the second position.

In such a vehicle hood lock structure, when the hood is fully closed, the biasing force of the elastic body rotates the operating lever to the first position where the hood is locked with respect to the vehicle body, thereby locking the hood with respect to the vehicle body. is locked. When opening the hood, the operating lever is rotated to the second position where the hood is unlocked from the vehicle body against the biasing force of the elastic body. When the operating lever is at the first position, the abutting portion provided on one of the base plate and the operating lever contacts the other of the base plate and the operating lever, so the operating lever is less likely to rattle. As a result, rattling of the operating lever is suppressed when the hood is locked with respect to the vehicle body. Further, when the operating lever is in the second position, the abutting portion provided on one of the base plate and the operating lever does not abut on the other of the base plate and the operating lever, so the abutting portion affects the operating force of the operating lever. never give.

One of the base plate and the operating lever may be provided with an elastic piece that biases the other side of the base plate and the operating lever, and the abutting portion may be provided at the tip of the elastic piece. In such a configuration, when the operating lever is at the first position, the contact portion contacts the other of the base plate and the operating lever due to the biasing force of the elastic piece provided on one of the base plate and the operating lever. Therefore, rattling of the operating lever can be suppressed with a simple structure.

The elastic piece may be provided directly below the shaft portion of one of the base plate and the operating lever and may extend in the vehicle width direction of the vehicle body. When the operating lever rotates between the first position and the second position, the portion of the operating lever below the shaft moves substantially along the vehicle width direction of the vehicle body. Therefore, since the other of the base plate and the operating lever can be easily engaged with the abutting portion, the operability of the operating lever is improved.

The elastic piece may be provided on the base plate and may contact the operating lever when the operating lever is in the first position. In such a configuration, since the elastic piece is provided on the base plate which does not move, the elastic piece is not easily affected by the space. Therefore, the contact portion can be brought into contact with the operating lever while the operating lever is in the first position while improving space efficiency.

The other of the base plate and the operating lever is provided with a protrusion projecting toward one side of the base plate and the operating lever. may not come into contact with the protrusion in the second position. In such a configuration, when the operating lever is in the first position, the contact portion contacts the protrusion, so the contact force of the contact portion increases. Therefore, rattling of the operating lever is further suppressed.

According to the present invention, rattling of the operating lever can be suppressed when the hood is locked with respect to the vehicle body.

When the hood 2 is locked with respect to the vehicle body 3 in this manner, rattling of the operation lever 6 is suppressed, so that the quality of the vehicle hood lock structure 1 can be improved. In particular, even if the operating portion 14 of the operating lever 6 is lengthened, the operating lever 6 is less likely to rattle. By lengthening the operating portion 14 of the operating lever 6 , the operator can easily operate the operating lever 6 . Furthermore, since the contact portion 23 that contacts the operating lever 6 can be provided on the base plate 5, rattling of the operating lever 6 can be suppressed without increasing the number of parts and without complicating the structure.

Further, in this embodiment, when the operating lever 6 is in the locked position, the contact portion 23 contacts the operating lever 6 due to the biasing force of the spring piece 22 provided on the base plate 5 . Therefore, rattling of the operating lever 6 can be suppressed with a simple structure.

In addition, in the present embodiment, the spring piece 22 is provided in a portion of the base plate 5 immediately below the shaft portion 11 and extends in the vehicle width direction of the vehicle body 3 . Therefore, when the operating lever 6 rotates between the locked position and the unlocked position, the portion of the operating lever 6 below the shaft portion 11 moves substantially along the vehicle width direction of the vehicle body 3 . become. Therefore, the operating lever 6 can be easily engaged with the contact portion 23, so that the operability of the operating lever 6 is improved.

Further, in this embodiment, since the spring piece 22 is provided on the stationary base plate 5, the spring piece 22 is less affected by the space. Therefore, the contact portion 23 can be brought into contact with the operating lever 6 while the operating lever 6 is in the locked position while improving the space efficiency.

In addition, in the present embodiment, when the operating lever 6 is in the locked position, the contact portion 23 contacts the protrusion 25 provided on the operating lever 6, so the contact force of the contact portion 23 increases. Therefore, rattling of the operating lever 6 is further suppressed.

In addition, this invention is not limited to the said embodiment. For example, in the above-described embodiment, the lower end of the operating lever 6 is provided with the protrusion 25 that protrudes toward the base plate 5 . , the protrusion 25 may be omitted. For example, if the spring piece 22 is provided at a position such that the operating lever 6 moves away when the operating lever 6 is rotated from the locked position toward the unlocked position, the projecting portion 25 may be omitted. good. In this case, the structure of the operating lever 6 can be simplified.

Further, in the above-described embodiment, the spring piece 22 provided on the base plate 5 extends in the vehicle width direction (Y direction), but the configuration is not particularly limited, and for example, as shown in FIGS. Alternatively, the spring piece 22 may extend in the vertical direction (Z direction) of the vehicle body 3 . 7 is a sectional view taken along line VII--VII of FIG. In this structure, the tip of the spring piece 22 is positioned below the base end of the spring piece 22 .

In the above-described embodiment, the base plate 5 is provided with the spring piece 22 and the operating lever 6 is provided with the protrusion 25. However, the configuration is not limited to this, and the configuration shown in FIG. As shown, the operating lever 6 may be provided with a spring piece 22 and the base plate 5 may be provided with a protrusion 25 .

In the above embodiment, when the operating lever 6 is in the locked position, the contact portion 23 provided at the tip of the spring piece 22 is pushed by the biasing force of the spring piece 22 provided on the base plate 5 to move the operating lever 6. However, it is not particularly limited to such a form. If the contact portion contacts the operating lever 6 when the operating lever 6 is in the locked position and the contact portion does not contact the operating lever 6 when the operating lever 6 is in the unlocked position, The contact portion may not be provided on the spring piece 22 .
