Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for a door lock striker of a door lock mechanism in a vehicle whose body is partially or entirely made of reinforced plastic.

[Prior art]

In the above-mentioned vehicle, a latch member constituting a door lock mechanism is attached to the edge of a door that opens and closes an opening provided in a part of the vehicle body, and a door lock that can be engaged with and detached from the latch member is attached to the edge of the opening. A vehicle is provided in which a striker is tightened and fixed via a mounting bolt, and a cover body formed of reinforced plastic is fixed to the outside of the opening edge, and the outside of the opening is covered with the cover body. be.

However, since the mounting portion of the door lock striker in such a vehicle receives the load applied to the door lock striker, it must have sufficient strength to withstand this load. For this reason, in conventional vehicles, as shown in FIG. 4, for example, the opening edge 2 of the opening provided at the back of the vehicle body, which is the attachment part of the door lock striker 1 (hereinafter referred to as the striker), is made thicker. , and the striker 1 is fastened and fixed via a steel retainer 3 with a plurality of mounting bolts 4a and nuts 4b. As a result, the striker 1 is removably positioned on the latch member 6 assembled to the back door 5, and locks the back door 5 when engaged with the latch member 6. Further, a load is applied to the striker 1 in the direction of arrow A when the backdoor 5 is opened and closed and when the vehicle is running, and this load is borne by the thick opening edge 2 and the retainer 3.

Therefore, although the conventional striker mounting structure has sufficient strength to withstand the load applied to the striker, in this mounting structure, the opening edge 2 of the vehicle body is considerably thicker than other parts. There are problems in that the retainer 33 must be made thick and must be made of steel.

[Purpose of the invention] The present invention was made to address these problems, and its main purpose is to effectively utilize not only the opening edge of the vehicle body but also the cover body as the attachment part for the striker. The purpose is to distribute this load between the opening edge of the vehicle body and the cover body, thereby reducing the thickness of the opening edge and omitting the use of a retainer during installation.

[Structure of the idea]

In order to achieve such an object, the present invention provides a vehicle of this kind as described above, in which a mounting bolt of the striker is fixed to the inside of the cover body, penetrates the opening edge, and projects inside the opening edge. The structure is characterized by the fact that the striker is tightened and fixed at the projecting end.

[Functions and effects of the idea]

As a result, in the mounting structure of the present invention, the load applied to the striker can be received by the opening edge of the vehicle body and the cover body via the mounting bolt, so that the opening edge of the vehicle body can be thickened unlike conventional methods. It is not necessary to interpose a steel retainer to ensure the strength of the attachment part.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 shows a part of an automobile employing the mounting structure of the present invention. Body 10 of this car
consists of a main body part 11 made of a steel plate, and an FRP body part 12 made of fiber-reinforced plastic that covers the rear cargo area of the main part 11 and forms a luggage compartment R. The back of the FRP body part 12 is an opening that opens the luggage compartment R. Opening edge 1 of this opening
A pair of left and right back doors 21 (only the right back door is shown) are attached to both sides 11a of the back of the main body portion 11 constituting the vehicle body 3, and these back doors 21 open and close an opening in the vehicle body 10. Further, a latch member 22 constituting a door lock mechanism is assembled to the upper left inner edge of the right back door 21. This door lock mechanism is conventionally known, and a latch member 22 releasably engages with a striker 23, which will be described later, to lock the right back door 21 as well as the left back door (not shown).

However, in the car, Figures 1 to 3
As shown in the figure, FRP forming the opening edge 13
A cover body 14 made of fiber-reinforced plastic is bonded to the entire back part 12a of the body part 12 via an adhesive, and two strikers 23 are attached to this cover body 14 and the back part 12a of the FRP body part 12. It is attached with bolts 24, 24.

As shown in FIG. 2 and FIG.
A pair of upper and lower boss portions 14a, 14a reaching the outer surface of the back portion 12a of the FRP body portion 12 are provided. In addition, on the back part 12a of the FRP body part 12,
A pair of upper and lower through holes 12b, 12b facing each boss portion 14a, 14a are provided. On the other hand, each mounting bolt 24, 24 is attached to each boss portion 14 of the cover body 14.
a, 14a, and protrudes into the inside of the back part by passing through each through hole 12b, 12b of the FRP body part 12.

The striker 23 is provided with a mounting bracket 23a approximately in the upper center thereof, and also has a bracket 23a for mounting.
Each through hole 12b, 1 of the FRP body part 12 is inserted into 3a.
A pair of upper and lower through holes 23b, 23b opposite to 2b
It is equipped with In such a striker 23, each mounting bolt 24, 24 is supported by each mounting bolt 24, 24 in a state where the inner end of each mounting bolt 24, 24 is passed through each through hole 23b, 23b of a bracket 23a, and each mounting bolt 24, 24 is It is tightened and fixed by nuts 25, 25 screwed onto the inner end of the holder.
As a result, the striker 23
It is firmly fixed to the inside of the back part 12a of 2 in a sandwiched state.

In the striker mounting structure configured as described above, the bracket 23a of the striker 23 is tightened and fixed to the back part 12a of the FRP body part 12 by each mounting bolt 24, 24 and each nut 25, 25 fixed to the cover body 14. . Therefore, when the vehicle is running, the load applied to the striker 23 in the direction of arrow A in FIG.
25 to the back part 12a of the FRP body part 12 and the cover body 14, and both these parts 12a,
14 will receive the above load at the same time. Therefore, in such a mounting structure, the cover body 14
By simply forming the respective boss portions 14a, 14a, the thickness of all or a considerable portion of the back portion 12a of the FRP body portion 12 is not thickened as in the conventional method, and a steel retainer for reinforcement is used. Sufficient strength can be ensured without any damage.

Furthermore, the mounting structure of the striker according to the present invention is as follows:
Of course, the present invention can be applied to a vehicle body partially or entirely made of reinforced plastic such as fiber-reinforced plastic.
