Description

  The present invention relates to an automobile rearview mirror support structure in which a rearview mirror is supported by a header panel disposed at a front end portion of a roof panel.

  The roof portion of an automobile generally has a structure in which the header panel is cantilevered by the front edge portion of the roof panel. If the rearview mirror mounting position is set on the rear portion of the header panel supported by such a cantilever, chatter vibration may occur in the rearview mirror due to vertical body vibration or the like, which may deteriorate the rear view.

  In order to prevent such chatter vibration of the rearview mirror, conventionally, for example, in Patent Document 1, a rein hose is provided on a roof inner panel (header panel), and a closed cross-section is formed by the rein hose and the roof inner panel. Thus, a structure is disclosed in which the support rigidity of the rearview mirror is increased.

  By the way, in the structure which increases the support rigidity of the rearview mirror by adding a rein hose to form a closed cross section as in the conventional case, there is a problem that the vehicle body weight and cost increase by adding a new rein hose. .

  The present invention has been made in view of the above-described conventional situation, and it is an object of the present invention to provide a vehicle rearview mirror support structure that can prevent chatter vibration of a rearview mirror without causing problems such as an increase in vehicle body weight or cost. Yes.

  The present invention relates to a vehicle room in which front flange portions of a roof panel and a header panel disposed in a front end portion of the roof panel and extending in the vehicle width direction are coupled to each other so that a rearview mirror is supported by the header panel. In the mirror support structure, a sliding member is disposed between the roof panel and the rear edge portion of the header panel so as to fill a gap between the roof panel and the rear edge portion of the header panel. It is characterized by arranging members.

  According to the rearview mirror support structure according to the present invention, the closing member is disposed in the gap between the roof panel and the rear edge portion of the header panel, and the sliding member with which the rear edge portion of the header panel contacts the lower surface of the closing member is provided. Since it has been arranged, kinetic energy such as vertical vehicle body vibration transmitted to the header panel is converted into frictional energy in the front-rear direction when the rear edge of the header panel is in sliding contact with the sliding member. As described above, the kinetic energy in the vertical direction is attenuated by converting it into the frictional energy in the front-rear direction, so that chatter vibration of the rearview mirror can be suppressed. Thereby, while being able to raise the freedom degree with respect to the attachment position of a room mirror, a back view can be ensured.

  Further, according to the present invention, the vehicle body vibration is attenuated by sliding the rear edge portion of the header panel against the sliding member. Therefore, the vehicle body weight is increased as compared with the case where the support rigidity is increased by adding a rein hose as in the prior art. In addition, an increase in cost can be suppressed.

  In the figure, reference numeral 1 denotes a truck cabin. The cabin 1 includes a front part 3 provided with a headlight 2, a left and right side part 5 provided with a door 4, and the left and right side parts. It has a structure in which a vehicle compartment R is formed by a back panel 6 and a roof portion 7 disposed at the rear end of the side portion 5. In addition, 9 is a loading platform.

A windshield 8 is disposed in the opening surrounded by the roof portion 7, the left and right side portions 5 and the front portion 3.

  The roof portion 7 is disposed to extend in the vehicle width direction on a roof panel 10 having an exterior surface, a ceiling member 12 laid on the indoor side of the roof panel 10, and a front end portion 10 a of the roof panel 10. Header panel 11.

  A front flange portion 10b is formed at the front end portion 10a of the roof panel 10, and a front flange portion 11b that is in contact with the lower surface of the front flange 10b is bent at the front end portion 11a of the header panel 11. The front flange portions 10b and 11b are coupled to each other by spot welding. An upper edge portion 8a of the windshield 8 is attached to a joint portion of the front flange portions 10b and 11b via a seal member (not shown).

  The header panel 11 has a flat plate portion 11c that extends rearward after the front end portion 11a, and a rear end portion 11d that bends and extends obliquely rearward and upward following the flat plate portion 11c.

  A predetermined gap s is provided between the rear end portion 11 d and the roof panel 10, whereby the header panel 11 is cantilevered by the roof panel 10.

  A mirror mounting seat 11e is formed at a central portion in the vehicle width direction of the flat plate portion 11c of the header panel 11, and a room mirror 15 is mounted on the mounting seat 11e.

  This rear mirror 15 has a mirror main body 15a for visually recognizing the rear of the vehicle, and a mounting bracket 15b connected to the mirror main body 15a. This mounting bracket 15b is bolted and fixed to the mirror mounting seat 11e of the header panel 11, and the interior side of the mounting bracket 15b is covered with a cover member 16. Reference numeral 17 denotes a room lamp attached to the mounting bracket 15b. When the room lamp 17 is turned on, the room lamp is irradiated through a lens (not shown) disposed on the cover member 16.

  The roof panel 10 and the rear end portion 11d of the header panel 11 and the gap s are provided with a closing member 20 that fills the gap s. The lower surface 20a of the closing member 20 has the rear end portion 11d. The sliding member 21 with which the upper end surface 11f of the abutment comes into contact is arranged.

  The closing member 20 has a vehicle width dimension corresponding to the mirror mounting seat 11e of the rearview mirror 15, and is adhesively fixed to the roof panel 10. The closing member 20 is made of an elastic member, for example, a urethane chip, and is sandwiched between the roof panel 10 and the header panel 11 with a slight elastic deformation a as shown by a two-dot chain line in FIG. ing.

  The sliding member 21 is bonded and fixed to the closing member 20, and is made of a thin plate-like material such as PP (polypropylene) having a lubricating function.

In this embodiment, a closing member 20 made of a urethane chip is disposed in the gap s between the roof panel 10 and the rear end portion 11d of the header panel 11, and the upper end surface of the rear end portion 11d is disposed on the lower surface 20a of the closing member 20. Since the sliding member 21 made of PP material with which 11f abuts is disposed, the kinetic energy in the vertical direction a due to vibration of the vehicle body or the like is in the longitudinal direction b with the upper end surface 11f of the header panel 11 in contact with the sliding member 21. By sliding, it is converted into friction energy. As described above, since the kinetic energy in the vertical direction a is attenuated by converting it into the friction energy in the front-rear direction b, chatter vibration of the rearview mirror 15 can be prevented. Thereby, the freedom degree with respect to the attachment position of the room mirror 15 can be raised, and it becomes possible to set to the rear part of the header panel 11 by extension. Moreover, since the chatter vibration of the room mirror 15 is prevented, a rear view can be secured.

  Further, in this embodiment, the rear end portion 11d of the header panel 11 is slidably contacted with the resin sliding member 21 with the resin closing member 20 interposed therebetween, so that the vehicle body vibration is attenuated. Compared to the case where a metal rein hose is added separately as in the conventional case to increase the support rigidity of the rearview mirror, an increase in vehicle weight and cost can be suppressed.
