Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle hood device which can be freely deployed and stored.

[0002]

2. Description of the Related Art In general, in a vehicle hood device, when used, the hood is extended from the rear of the vehicle compartment to the front of the vehicle compartment to cover the upper part of the vehicle compartment. To open the upper part of the cabin. Various types of hoods have been conventionally proposed as deployment and storage modes, one of which is known as shown in FIGS. 9 and 10.

[0003] A first folding member 101 and a second folding member 10 which can be freely bent are provided on both right and left sides of the hood structure.
2 comprising side members 100 and 100
The hood 104 supported by the hood mechanism has a side edge 104 of a portion corresponding to the first bending member 101 located on the front side of the vehicle body.
a is fixed to the first bending member 101, and a peripheral edge 104c corresponding to the opening edge 110 of the vehicle body is fixed to the vehicle body side.

On the other hand, a side edge 104c of a portion of the hood 104 corresponding to the second bending member 102 is free. When the hood mechanism is deployed, the side edge 104c is moved along with the deployment operation of the second folding member 102 toward the front side of the vehicle body, as shown in FIG.
Is pulled out to the front side of the vehicle body, thereby approaching the second bending member 102 side and being brought into contact with the periphery thereof. On the other hand, at the time of the storing operation from the expanded state of the hood bone mechanism, the side edge 104c is separated from the peripheral edge of the second bending member 102 by the tilting of the second bending member 102 toward the rear side of the vehicle body, Eventually it will be folded at the rear of the vehicle. Particularly, when the hood is deployed, the side edge 104c of the hood 104 is aesthetically or functionally attached to the second bent member 1.
02 is required to be properly in contact with the peripheral portion of the second member.

[0005]

As described above, the side edge 104c of the hood 104 is brought into contact with the second bent member 102 which tilts in the longitudinal direction of the vehicle body when the hood is deployed, and the hood is stored in the hood storage state. In the configuration in which the tops are separated from each other, the side edges 1 of the tops 104 in the top deployment state
The contact action (pressing action) of the second bending member 102 on the peripheral portion of the second bending member 102 is performed by the first bending member 101 and the second bending member 102.
This is achieved by that the side edge 104c is attracted to the front side of the vehicle body as the bending member 102 moves toward the front side of the vehicle body.

However, the moving force of the second bending member 102 toward the front side of the vehicle body extends in the extending direction (ie, the direction along the bent shape) at the side edge 104c of the hood 104.
Mainly, and the component of the tension toward the front side of the vehicle body acts as a force for pressing the side edge 104c against the peripheral edge of the second bending member 102. Accordingly, as the bending angle of the second bending member 102 increases, the side edge 104 with respect to the peripheral edge of the second bending member 102 increases.
The pressing force of c will decrease. Further, the hood 104 has relatively high rigidity of the hood cloth itself, and becomes a resistance when the side edge 104c is pressed against the peripheral edge side of the second bent member 102.

As a result, when the hood is deployed, the side edge 104c of the hood 104 is pulled toward the periphery of the second bent member 102, as shown by a dashed line in FIG. 9 (see reference numeral 104c '). Is insufficient, and a part of the side edge 104c is separated from the peripheral portion of the second bending member 102, thereby causing a problem such as deterioration in aesthetics in a deployed state of the hood or deterioration in sealing performance. It is feared that it will occur.

Accordingly, the present invention relates to a vehicle hood device,
The purpose is to improve the aesthetics and functionality of the hood in the deployed state.

[0009]

According to the present invention, the following configuration is employed as specific means for solving the above-mentioned problems. That is, the hood support member 15 which has a substantially curved shape and is tiltable in the front-rear direction of the vehicle body, is located closer to the rear of the vehicle body than the hood support member 15, and follows the deployment / retraction operation of the hood support member 15. A hood bone mechanism 12 having a hood bone 17 capable of tilting in the vehicle front-rear direction, and a cover that covers the outside of the hood bone mechanism 12 and is deployed and stored with the deployment and storage operation of the hood bone mechanism 12. And a side edge 11a corresponding to the top support member 15 of the top 11
In a vehicle hood device configured to be in contact with the peripheral edge of the hood support member 15 in the deployed state of the hood support mechanism 12 and to be separated from the peripheral edge of the hood support member 15 in the retracted state, A hood cloth pulling means Z for pulling the hood cloth at a position closer to the rear of the vehicle body than the side edge 11a of the hood 11 to the front side of the vehicle body by the operating force of the hood bone 17 accompanying the deployment operation of the hood bone mechanism 12. It is characterized by having been provided.

[0010]

According to the hood device for a vehicle according to the present invention,
Side edge 11a of the top 11 corresponding to the top support member 15
_{Since the} hood cloth pulling means Z for pulling the hood cloth closer to the rear of the vehicle body than _2, to the front of the vehicle body by the operating force of the hood bone 17 accompanying the deployment operation of the hood bone mechanism 12 is provided, Since the top support member 15 has a substantially curved shape, the top support member 15 on the side edge 11a of the top 11 due to the moving force of the top support member 15 toward the front of the vehicle body.
Even if the pressing efficiency against the peripheral portion is low, the pressing efficiency is low because the hood cloth drawing means Z is
The hood 11 is actuated by receiving the operating force of the hood 17 which tilts following the movement of the hood 11. The hood 11 is compensated by pulling the hood 11 toward the periphery of the hood support member 15, so that the side edge 11 of the hood 11 is compensated.
a is more reliably pressed against the peripheral edge of the hood support member 15, and the situation where the side edge 11a of the hood 11 is separated from the peripheral edge of the hood support member 15 in the hood deployment state is prevented beforehand. As a result, the aesthetics in the deployed state of the top can be maintained well, and a great effect can be expected in terms of functions such as improvement in sealing performance.

Is securely contacted. As a result, the aesthetic appearance in the deployed state of the hood is favorably maintained, and
A high sealing property between the first strip 1a and the weather strip 29 on the second bending member 15 side is ensured.

At the time of storing operation of the hood device 10 The storing operation of the hood device 10 is performed from the hood unfolded state shown in FIG. That is, first, the lock mechanisms 9, 9 are detached from the lock receiving members 26, 26. Thereafter, the operating handle 28 is used to apply an operating force to the lateral member 19 toward the rear of the vehicle body to gradually bend the hood bone mechanism 12 from the deployed state. Finally, as shown in FIG. The lock mechanisms 9, 9 are fixed to the lock receiving members 27, 27, and the procedure is completed. In the hood retracted state of the hood device 10, the folded portion 11a of the hood 11 is folded inward.
