Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the front body structure of a cab-over type automobile, and more particularly to the structure of a reinforcing member extending over an engine service hole and a service hole cover that closes the engine service hole.

For cab-over type vehicles in which the passenger cabin is placed above the engine, the engine is covered from above by the cabin floor panel, so for engine maintenance and repairs, it is necessary to remove a portion of the floor panel. Conventionally, a front body structure has been used in which an engine service hole is provided to expose the upper part of the engine, and the service hole is normally closed by a service hole cover fixed to the bottom of the passenger seat. ing.

In cab-over type automobiles with the above-mentioned front body structure, the service hole cover is flipped up along with the seat bottom to open the engine service hole. It is desirable to form However, if this engine service hole is made too large, the rigidity of the floor panel decreases, making it more likely to be deformed by external forces.

For example, as shown in Japanese Utility Model Application Publication No. 54-43713, a reinforcing member that crosses a part of a large engine service hole is removably fixed to the floor panel to increase the rigidity of the floor panel. There is also a vehicle body structure in which repairs are performed with the reinforcing member fixed, and large-scale maintenance and repairs of the entire engine are performed by removing the reinforcing member and opening the entire engine service hole.

In general, reinforcing members such as those described above are installed near the center of the cabin to extend in the longitudinal direction of the vehicle body in order to effectively increase the rigidity of the floor panel. It is often used to secure seat belt anchors that support.

However, in order to ensure a large effective opening area of the engine service hole, this reinforcing member cannot be made too large, and therefore its strength is naturally limited. Therefore, when a car crashes, if a large load is applied from the seat belt via the seat belt anchor, the seat belt easily deforms, causing a problem in that the seat belt does not function adequately to protect the occupant.

The present invention has been developed in view of the above circumstances, and even if the reinforcing member to which the seat belt anchor is fixed is made small, the reinforcing member will not easily deform, thus preventing a car from colliding. It is an object of the present invention to provide a front body structure for a cab-over type automobile, in which occupants can be safely protected by seat belts even when the occupants are seated.

The front body structure of the cab-over type vehicle of the present invention is a body structure in which a reinforcing member to which the seat belt anchor is fixed as described above is installed, and a fixing member is provided to fix the service hole cover to the vehicle body when the service hole is closed. The reinforcing member is provided with a hook locking hole, and the service hole cover is provided with a hook that locks into the hook locking hole when the service hole is closed.

If the reinforcing member and the service hole cover are connected by the engagement between the hook and the hook locking hole, the load acting on the reinforcing member will be firmly supported by the floor panel via the seat fixing part. Since the reinforcing member can also be received by the service hole cover, even if the reinforcing member is made small, the reinforcing member will not be easily deformed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing the front body structure of a cab-over type automobile according to an embodiment of the present invention, and FIG. 2 is a side view thereof. As shown in FIG. 2, the cabin 1 has seats 2a and 2b connected to the engine 3.
It is located almost directly above the cab, making up a typical cab-over type automobile. A floor panel 4 forming the floor surface of the cabin 1 extends to cover the engine 3 from above, and as shown in FIG. A service hole 5 is provided.

A reinforcing member 6 is fixed to the floor panel 4 so as to extend near the center of the cabin 1 in the longitudinal direction of the vehicle body (vertical direction in FIG. 1) and across the engine service hole 5. By installing this reinforcing member 6, a large engine service hole 5
The rigidity of the floor panel 4 provided with this is increased, and the floor panel 4 is not easily deformed by external loads. Note that this reinforcing member 6 is removably fixed to the floor panel 4 with bolts 7.

Service hole covers 8a and 8b are arranged on the left and right sides of the reinforcing member 6, and the engine service holes 5 on the left and right sides of the reinforcing member 6 are respectively closed from above by these service hole covers 8a and 8b. As shown in FIG. 2, the rear end of the service hole cover 8a on the left side of the vehicle body of the reinforcing member 6 is rotatable by a hinge 10a with respect to a support member 9a fixed near the rear end of the floor panel 4. is supported by the service hole cover 8.
A hook 12a is fixed to the front end of a, which is hooked to a hook 11a fixed to the floor panel 4. The seat 2a (passenger seat) is fixed to the upper surface of this service hole cover 8a, and when the service hole cover 8a is placed on the floor panel 4 so as to close the engine service hole 5 from above (the (state shown in Figure 2), the seat can be set to a ready state. And hook 12a
is removed from the locking tool 11a, the passenger seat 2a is folded so that the seat back and the seat bottom are aligned, and the service hole cover 8a is removed.
When the engine service hole cover 5 is flipped up rearward about the hinge 10a, the engine service hole cover 5 is opened. As mentioned above, in this embodiment, the support member 9
a, the hinge 10a, the locking tool 11a, and the hook 12a constitute a fixing member that fixes the service hole cover 8a to the vehicle body when the service hole is closed.

A seat rail (not shown) on the center side of the vehicle body of the seat 2b (driver seat) is placed on the service hole cover 8b on the right side of the vehicle body of the reinforcing member 6, and a seat rail on the outside of the vehicle body of the seat 2b is placed on the floor panel 4 on the right side of the vehicle body. (not shown) are fixed respectively, and this service hole cover 8b is fixed with bolts (not shown).
It is fixed to the floor panel 4 by. The service hole cover 8c is also bolted (not shown).
It is fixed to the floor panel 4 by.

When maintaining or repairing the engine 3, the service hole cover 8a is flipped up backward to open the engine service hole 5, and various maintenance or repair work is performed from this engine service hole 5. , 8c are removed. Further, in case of large-scale maintenance or repair covering the entire engine 3, the reinforcing member 6 is removed from the floor panel 4 by loosening the bolt 7, and the entire surface of the engine service hole 5 is opened.

A parking brake 13 is attached to the reinforcing member 6, and a seatbelt anchor 14 that supports one end of the seatbelt is fixedly installed, and a hook locking hole 15 is provided near the seatbelt anchor 14. (See Figure 1). FIG. 3 is a sectional view of the vicinity of the hook locking hole 15 as viewed from the front side of the vehicle body. As shown in FIG. 3, the lower surface of the service hole cover 8a protrudes downward to provide the reinforcement when the service hole cover 8a is set in the position where the engine service hole 5 is closed (the state shown in FIG. 3). Part 6
A hook 16 that locks into the hook locking hole 15 is fixed. This hook 16 can be biased by a biasing means to be tightly locked in the hook locking hole 15, as has conventionally been done with various locking hooks.

When a car crashes, a large load applied to the seat belt is received by the floor panel 4 via the seat belt anchor 14, the reinforcing member 6, and the bolt 7. At the same time, in this embodiment, since the reinforcing member 6 and the service hole cover 8a are connected via the hook 16 as described above, the load acting on the reinforcing member 6 is transferred to the hook 1.
