BACKGROUND OF THE INVENTION
The present invention relates to a vehicle body mounting structure for an automobile door mirror in which a door mirror is mounted on a belt line portion of a front door having a fixed window.
[0002]
[Prior art]
In general, when a door mirror is attached to a front door having a fixed window, the mirror base may be bolted and fixed to the beltline portion of the door outer panel at two points in front and rear so as not to impair the exterior design of the door surface (for example, specially (See Kaihei 8-142753). However, in the case where the mirror base is bolted and fixed at two front and rear points, there is a concern that the mirror base is likely to wobble due to an external force or to cause specular chatter during traveling.
[0003]
In order to prevent such wobbling and specular chatter due to external force, conventionally, a mirror base has been proposed that is bolted and fixed at three points: a belt line of a door outer panel and a flange portion at the top of the belt line (for example, (See Japanese Utility Model Publication No. 5-44640). Further, there has been proposed one in which a mirror base is fixed to a corner piece of a door inner panel at three points (see, for example, Japanese Patent Application Laid-Open No. 11-5444).
[0004]
[Problems to be solved by the invention]
However, when the structure is fixed at the three points of the belt line of the door outer panel and the upper flange portion of the above-mentioned conventional publication, it is difficult to take the span of each fixing point, and sufficient mounting rigidity may not be secured. is there.
[0005]
Here, to increase the mounting rigidity, it is conceivable to secure a span by setting one fixing point below the belt line, but in this case, the exterior design of the door surface is impaired. Occurs.
[0006]
In addition, when the mirror base is fixed to the corner piece of the door inner panel of the above-described conventional publication at three points, there is a problem that the mounting rigidity is easy to ensure, but it cannot be adopted for the front door having a fixed window.
[0007]
The present invention has been made in view of the above-described conventional situation, and can improve the mounting rigidity without impairing the external design when a door mirror is attached to a door having a fixed window, thereby preventing wobbling and mirror chatter due to external force. An object of the present invention is to provide a vehicle door mirror mounting structure that can be used.
[0008]
[Means for Solving the Problems]

[0044]
According to the belt line reinforcement structure of the present embodiment, the belt line rein hose 20 has a single closed cross section by joining the outer rein hose 21 and the inner rein hose 22 in the middle. Since the first and second closed cross sections A and B extending over the entire length in the front-rear direction of the door body 4a are formed by the rein hose 20 and the door inner panel 11, the belt line is compared with the case of passing through one conventional closed cross section. The rigidity in the L part can be increased, and the cross-sectional collapse at the time of offset collision can be prevented.
[0045]
Thereby, the input from the apron member 7 can be efficiently transmitted to the beltline reinhose 20 via the upper hinge member 16, the door deformation at the time of a collision can be prevented, and the influence on the room can be prevented.
[0046]
Moreover, since the cross-sectional shape of the beltline reinhose 20 is made continuous in the front-rear direction, step points can be eliminated over the entire length of the beltline reinhose 20, and the cross-sectional shape can be prevented from changing when the cross-sectional shape is changed halfway. It is possible to further increase the rigidity at the belt line L portion.
[0047]
In the present embodiment, the beltline reinhose 20 has a single closed cross-sectional shape, a closed cross-sectional structure in which the front side is enlarged in the vertical direction from the rear side, and is gently inclined in the front-rear direction, and the front end surface is aproned. Since it is made to oppose the back of the member 7, the impact force from the apron member 7 can be reliably transmitted to the beltline reinhose 20, and the influence on a vehicle compartment can be prevented reliably.
[0048]
Moreover, since the longitudinal cross-sectional shape of the inner rein hose 22 is substantially the same cross-sectional shape over the entire length, the step point due to the cross-sectional change when the front closed cross section of the belt line rein hose 20 is enlarged can be eliminated, Cross-section collapse can be reliably prevented.
[0049]
In the present embodiment, the flange portion 22a is formed at the front end portion of the inner hose 22, and the flange portion 22a is coupled to the hinge mounting portion 11b, so that the mounting strength and rigidity can be increased without increasing the number of parts. it can.
[0050]
In the above embodiment, a case where two closed cross sections, that is, a first closed cross section A formed by the beltline rein hose 20 alone and a second closed cross section B formed by the door inner panel 11 and the inner rein hose 22 is described. However, the present invention may form three or more closed cross sections. For example, a reinforcing portion that extends downward is integrally formed on the door mirror rein hose 40, and an extended lower end portion of the reinforcing portion is joined to the lower edge portions 21c and 22c of the beltline rein hose 20 so that the reinforcing portion and the inner rein hose are joined. 22 may form a third closed cross section. In this case, three closed sections can be formed at the front part of the door, and the rigidity can be further increased.
