Next, the operation and effect of this embodiment will be described.

  In the front side door module 10 according to the present embodiment, a door outer subassembly 12, a framework lifting module 14, and a trim module 16 are assembled and prepared in advance. First, the framework lifting module 14 is assembled to the door outer subassembly 12 from the vehicle interior side using the module assembly opening 24. Specifically, the door lock reinforcement 42 is on the rear part 20B of the door inner panel 20, the door hinge reinforcement 40 is on the front part 20A of the door inner panel 20, and the motor bracket 56 and the lower pulley bracket 66 are on the lower end part 20D of the door inner panel 20. The intermediate member 46 is fixed to the upper end portion 20C of the door inner panel 20 with a bolt and a weld nut, respectively. The bolts are screwed in from the door rear side for the door lock reinforcement 42, from the door front side for the door hinge reinforcement 40, and from the vehicle interior side for the motor bracket 56, the lower pulley bracket 66, and the intermediate member 46, respectively.

  At this time, the rear end portion 44A of the impact beam 44 is aligned with the thin door portion 100 of the door outer subassembly 12 and is bolted at two upper and lower points, so that the rear end portion 44A of the impact beam 44 is It is fixed to the door thin wall portion 100 of the panel 20. The front end portion 44B of the impact beam 44 is similarly bolted and fixed at two upper and lower points.

A long impact beam 44 made of a high-strength member is disposed in the vicinity of the lower end of the module 14, and the impact beam 44 is disposed so as to straddle the module assembly opening 24 in the front-rear direction of the door. Thus, since the door hinge reinforcement 40 and the door lock reinforcement 42 are connected, the rigidity reduction of the door outer subassembly 12 is sufficiently compensated.

  Further, in the front side door module 10 having the above structure, the door thin portion 100 which is thinner than the door general portion 98 is formed below the rear portion of the door inner panel 20 of the door outer subassembly 12. The rigidity of the is particularly weak. However, in the front side door module 10 according to the present embodiment, after the rear end portion 44A of the impact beam 44 is extended to the door thin portion 100, the rear end portion 44A of the impact beam 44 is connected to the door thin portion 100. The door thin-walled portion 100 is sufficiently reinforced. Therefore, if the rear end portion 44A of the impact beam 44 in which the front end portion 44B is coupled to the door hinge reinforcement 40, which is a door installation reference, is coupled to the door thin portion 100, the door is easily deformed by the heat of the painting process. The position (displacement in the vehicle width direction) of the thin portion 100 can be easily adjusted (that is, the deformation generated in the door thin portion 100 can be corrected). That is, the installation of the lower part of the rear part of the door outer subassembly 12 can be easily adjusted. For this reason, the continuity of the design of the front side door 86 and the rear side door 88 can be ensured. As a result, according to the present embodiment, the appearance quality of the vehicle is improved (by suppressing the deformation of the door thin portion 100 using the long impact beam 44 arranged along the front-rear direction of the door). Can be made.

  Further, in the front side door module 10 according to the present embodiment, the skeleton module 48 holds the front portion 38A of the door frame 38 and holds the door hinge reinforcement 40 that is long in the vertical direction of the door and the rear portion 38B of the door frame 38, and in the vertical direction of the door. The structure includes a long door lock reinforcement 42, and a high-strength impact beam 44 is stretched between the lower ends of the door hinge reinforcement 40 and the door lock reinforcement 42 to connect them to each other. 48 can be obtained, and as a result, the skeleton module 48 can be prevented from being twisted.

  The impact beam 44 is arranged on the frame module 48 side and attached to the door inner panel 20 of the door outer subassembly 12 from the vehicle interior side, so that the installation work of the impact beam 44 is facilitated and the installation location (bolt fastening) There is also an advantage that it can be easily accessed from the vehicle interior side.

  Further, in the front side door module 10 according to this embodiment, the rear end portion 44A of the impact beam 44 is coupled to the door thin portion 100 in a state where the rear end portion 44A extends to a position where it overlaps with the lower portion 102A of the center pillar 102 in a side view. Therefore, the load at the time of a side collision can be transmitted (flowed) from the rear end portion 44A of the impact beam 44 to the lower portion 102A of the center pillar 102. Therefore, the amount of energy absorption at the time of a side collision can be increased. Further, the amount of the front side door 86 entering the vehicle interior side at the time of a side collision is reduced (that is, even if the door outer subassembly 12 is deformed to the vehicle interior side, the rear end portion 44A of the impact beam 44 is centered. By contacting the lower part 102A of the pillar 102, the input load at the time of a side collision is distributed to the body via the center pillar 102. As a result, the amount of the door outer subassembly 12 entering the vehicle interior is reduced. You can also As a result, according to the present embodiment, occupant protection performance at the time of a side collision can be improved.

  Further, in the front side door module 10 according to the present embodiment, the door weather strip 118 is disposed on the outer peripheral plane portion 74A of the door trim main body 74 of the trim module 16, and the seal line S is the door of the impact beam 44 in a side view. Since the portion extending to the thin portion 100 (rear end portion 44A) is arranged so as to cross, the door weather strip 118 of the door weather strip 118 can be formed even if the impact beam 44 has an uneven surface or the like. It has no effect on sealing performance. In other words, since the sealing property of the door weather strip 118 can be ensured, the rear end portion 44 </ b> A of the impact beam 44 can be extended to the door thin portion 100 and coupled. As a result, according to the present embodiment, good sealing performance can be ensured.

  Further, in the front side door module 10 according to the present embodiment, the door trim body 74 is modularized to form the trim module 16, thereby reducing the assembly process and facilitating the assembly work. As a result, according to this embodiment, the assembly time of the front side door module 10 can be shortened.

  Furthermore, in the front side door module 10 according to the present embodiment, the door lock reinforcement 42 used for attaching the door lock to the rear end portion 44A of the impact beam 44 at a position overlapping the lower portion 102A of the center pillar 102 in a side view. Since the lower end portion of the impact beam 44 is coupled, a load is transmitted from the rear end portion 44A of the impact beam 44 to the door lock reinforcement 42 and further from the door lock reinforcement 42 to the center pillar 102 via the main body 70 (and striker). Is done. Therefore, energy absorption at the time of a side collision is performed quickly. As a result, according to the present embodiment, occupant protection performance at the time of a side collision can be improved.

  In addition, the load input to the door lock device 68 and further to the door lock reinforcement 42 from the striker provided in the body at the time of strong closing can be distributed to the impact beam 44 and thus the entire front side door 86.

  Further, in the front side door module 10 according to the present embodiment, the door lock reinforcement 42 includes the vertical wall portion 42B that rises in the door thickness direction along the peripheral edge portion of the module assembly opening 24. Since the bead 116 that increases the rigidity in the door thickness direction is set in the portion 42B, the load at the time of the side collision can be transmitted to the center pillar 102 more rapidly. As a result, according to the present embodiment, the occupant protection performance at the time of a side collision can be further improved.

  Further, in the front side door module 10 according to the present embodiment, the intermediate portion of the impact beam 44 and the door thin portion 112 on the lower edge side of the door outer subassembly 12 are connected by the bracket 92, so that the rigidity of the door thin portion 112 is increased. Can be increased. Therefore, deformation of this part can be suppressed. As a result, the installation adjustment of the lower side of the front side door module 10 becomes easy.

  In addition, the door overstroke stopper 114 is disposed within a triangular range connecting the fastening point (two places) of the rear end portion 44A of the impact beam 44 and the fastening point (one place) of the bracket 92. At times, the input load from the stopper 114 to the thin door portion 100 can be dispersed in the impact beam 44. As a result, deformation of the door thin portion 100 can be suppressed.
