Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rear structure of a vehicle having a luggage door, a back door or the like at the rear of the vehicle body.

[0002]

[Prior Art]

 As this type of vehicle, it is known that a luggage room for storing luggage is provided at the rear part of the vehicle body, and a flip-up type luggage door is attached from the upper part to the rear part of the luggage room. In the rear structure of this vehicle, as shown in FIG. 6, a lower back reinforcing member 4 is fixed by spot welding along the vehicle width direction inside the lower back panel 3 forming the outer surface of the rear part of the vehicle body. A retainer 6 is provided at the center in the vehicle width direction, the upper end of which is fixed by the panel 3 and the reinforcing member 4 and the lower end of which is fixed inside the panel 3. A striker 7a of a lock device 7 for fixing the luggage door 2 in a closed state is attached to an upper portion of the retainer 6. Further, the reinforcing member 4 located above the striker 7a attached to the retainer 6 is formed with an upper opening 4a for locking the hook of the lock device 7 attached to the luggage door 2, and below the striker 7a. A lower opening 4b for attaching the ground terminal 9a for the ground wire 9 of the rear combination lamp or the wire harness 8 of the courtesy switch to the retainer 6 is formed in the reinforcing member 4 located at.

[0003]

[Problems to be solved by the device]

 However, in the rear structure of the above-mentioned vehicle, since the lower opening is formed in the reinforcing member, the rigidity of the lower back panel cannot be sufficiently secured, and the impact due to the closing operation of the luggage door and the external impact on the lower back panel are not achieved. There was a risk that the lower back panel would be deformed due to factors such as the above.

An object of the present invention is to provide a rear structure of a vehicle capable of increasing the rigidity of a lower back panel without increasing the number of parts and assembling steps.

[0005]

[Means for Solving the Problems]

 A configuration of the present invention for achieving the above object will be described with reference to FIGS. 1 and 5 corresponding to the embodiment. The present invention includes a lower back panel 13 that forms a rear outer surface of a vehicle body together with a flip-up type opening / closing body 12 provided at the rear portion of the vehicle body, and a lower back reinforcing member 14 fixed inside the panel 13 along the vehicle width direction. And a retainer 16 having an upper end sandwiched between the panel 13 and the reinforcing member 14 and a lower end fixed to the inside of the panel 13, and an opening / closing body 12 having a locking portion and a locked portion 17a. A locking device 17 for locking the lock member 17, the locking portion is attached to the opening / closing body 12, the locked portion 17a is attached to the retainer 16, and the reinforcing members 14 above and below the locked portion 17a attached to the retainer 16 are provided. It is an improvement of the rear structure of the vehicle in which the upper opening 14a and the lower opening are formed respectively. The characteristic structure is that a projecting portion 14b is extended from the reinforcing member 14 toward the retainer 16 so as to close the lower opening, and the tip of the projecting portion 14b is fixed to the retainer 16 with a bolt 21. Further, the locking portion of the locking device 17 can be attached to the retainer 16, and the locked portion 17a can be attached to the opening / closing body 12.

[0006]

[Action]

 Since the protruding portion 14b of the lower back reinforcing member 14 closes the lower opening and the tip of the lower back reinforcing member 14 is fixed to the retainer 16 with the bolt 21, the impact due to the closing operation of the opening / closing body 12 and the external impact on the lower back panel 13 are caused. The lower back panel 13 will not be easily deformed even if a force is applied.

[0007]

【Example】

Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 5, a luggage room 11 for accommodating luggage is provided at the rear of the vehicle body of the passenger car 10, and a flip-up type luggage door 12 is attached from the top to the rear of the luggage room 11 (see FIG. 5). A rear outer surface of the vehicle body is formed by the lower back panel 13 together with the luggage door 12 when closed, and a lower back reinforcing member 14 is fixed to the inside of the panel 13 by spot welding along the vehicle width direction. A retainer 16 is provided inside the center of the panel 13 in the vehicle width direction, the upper end of which is sandwiched between the panel 13 and the reinforcing member 14, and the lower end of which is fixed inside the panel 13. As shown in FIG. 4, the pitch P ₁ of spot welding for fixing the lower edge of the reinforcing member 14 to the inner surface of the panel 13 is formed wider than the normal pitch P ₂ only in the portion straddling the retainer 16 (FIG. 4). .. The spot-welded portion has a closed cross section formed by the panel 13 and the reinforcing member 14 (FIG. 2), and the non-spot-welded portion is formed so that the lower end of the reinforcing member 14 does not adhere to the panel 13 (FIG. 2). 3).

As shown in detail in FIG. 1, a striker 17 a of a locking device 17 for fixing the luggage door 12 in a closed state is attached to an upper portion of the retainer 16, and the luggage door 12 facing the striker 17 a when the luggage door 12 is closed is attached to the luggage door 12. Is attached with a hook (not shown). The reinforcing member 14 located above the striker 17a attached to the retainer 16 is formed with an upper opening 14a for locking the hook of the locking device 17 attached to the luggage door 12 to the striker 17a. A wire harness 18 for a rear combination lamp or courtesy switch is inserted between the panel 13 and the retainer 16.

The characteristic structure of the present embodiment is that a protrusion 14b for closing the lower opening, which is conventionally formed below the striker 17a, is extended from the reinforcing member 14 toward the retainer 16, and this protrusion is formed. The tip of 14b is fixed to the retainer 16 with a bolt 21. The bolt 21 is a bolt for mounting a ground terminal in this example, and a nut 22 to which the bolt 21 can be screwed is welded to the rear surface of the retainer 16.

The operation of the rear structure of the vehicle thus configured will be described. The bolt 21 is screwed to the nut 22 welded to the rear surface of the retainer 16 via the ground terminal 19a of the ground wire 19 of the wire harness 18, the protrusion 14b of the reinforcing member 14 and the retainer 16 (FIG. 1). As a result, the panel 13 is easily deformed even if an impact due to the closing operation of the luggage door 12 or an impact from the outside on the lower back panel 13 is applied without increasing the number of parts and the number of assembling steps. Therefore, the rigidity of the panel 13 can be increased.

In the embodiment, the tip of the protruding portion of the reinforcing member is fixed by using the bolt for mounting the ground terminal, but this is an example, and bolts other than the bolt for mounting the ground terminal, etc. You may fix by. Alternatively, a screw hole may be formed in the retainer without welding the nut on the back surface of the retainer. Further, in the embodiment, the passenger car having the luggage door at the rear of the vehicle body is described, but the present invention is not limited to this, and a hatchback vehicle having a back door at the rear of the vehicle body may be used. Further, hooks may be attached to the retainer instead of the striker. In this case, the striker engaging with the hook is attached to the luggage door.

[0012]

[Effect of the device]

 As described above, according to the present invention, since the protrusion of the lower back reinforcing member closes the lower opening and the tip thereof is fixed to the retainer, the impact due to the closing operation of the opening / closing body and the external force to the lower back panel from the outside. Even if an impact is applied, the lower back panel does not easily deform, and the rigidity of the lower back panel increases. Also, the structure of the present invention can be formed with almost the same parts and assembling steps as before. Further, if the structure of the present invention provides excessive rigidity, it becomes possible to widen the pitch of spot welding of the reinforcing member and reduce the plate thickness of the reinforcing member or the lower back panel.
