In addition in the above-described embodiment, though rib 10a, 10b extend with rectilinear form roughly, rib 10a, 10b also can extend with bend mode in the scope that does not hinder the object of the invention (technical problem) among the present invention.
(the 4th embodiment)
Next, the present invention's the 4th embodiment is described.At first, describe with reference to figure 9 to Figure 13 structures present embodiment.
The skeleton diagram of the vehicle of Fig. 9 is the installation observed from rear the present invention's the 4th embodiment Hatchback door structure.
The Hatchback door structure 201a of present embodiment is made of wainscot 202a and outer panels 203.Hatchback door structure 201a is installed on the vehicle V by hinge 214.Wainscot 202a and outer panels 203 make up in modes such as crimping processing or spot welding.On wainscot 202a, be formed with along the 204a of frame portion of the outer shape of Hatchback door structure 201.On the 204a of frame portion, be formed with the 205a of window frame portion that window glass 207 is installed, crossbeam 206a also is installed.Be formed with lock installation portion 210 in the lower end of the 204a of frame portion.
Figure 10 is the stereogram of the employed wainscot of present embodiment Hatchback door structure.Top at the 204a of frame portion that constitutes wainscot 202a is formed with the 205a of window frame portion.The 204a of this frame portion is shaped by punch forming.At weld part 213,213 places of a pair of window frame 205a of the portion side that is positioned at this window frame portion 205a lower end, the crossbeam 206a of split is mounted by spot welding from the car outside.Like this, in the gamut of the peristome between a pair of weld part 213,213 crossbeam 206a is installed.And, in the present embodiment, though, also can it be installed in the weld part 213,213 of the 205a of window frame portion from the car inboard for the intensity that makes the collision of reply when closing rear door improves and from the car outside crossbeam 206a is installed.
On crossbeam 206a top, be provided with the peristome 208a that window glass is installed.In addition, in the bottom of crossbeam 206a, be provided with peristome 209a.In the outer edge of these peristomes 208a, 209a, be formed with and cut wall 211a.Cut wall 211a and had the effect of raising with respect to the rigidity of the bending of wainscot 202a.
Figure 11 (a) is the stereogram of the crossbeam 206a of employed split in the present embodiment.Figure 11 (b) is the C-C sectional view of employed crossbeam 206a central portion in the present embodiment.Thereby crossbeam 206a is by the parts (with reference to figure 9 and Figure 10) of punch forming with respect to the 204a of the frame portion split shaping of wainscot 202a.Crossbeam 206a is formed with the weld part 223,223 of pair of beams 206a side at its two ends.This is in the same plane to weld part 223,223, and spot welding is to the 205a of window frame portion as previously mentioned, and the 205a of this window frame portion is formed on the 204a of frame portion that constitutes wainscot 202a and goes up (with reference to Figure 10).
The height of having cut portion 222 uprises to central portion from the two ends of beam portion 221.Reach maximum height L 3 at central portion.Therefore, the sectional area of crossbeam 206a becomes central portion maximum, arc in the two ends of crossbeam portion 221 minimum.By such mode, make the flexural stress that puts on crossbeam 206a in crossbeam 206a, become even.
In addition, because crossbeam 206a and the 204a of frame portion split shaping, so the degree of freedom of its shape is than crossbeam 206c (with reference to Figure 15) height in the existing example.Cut wall 211c height such as, the maximum height L 3 of the portion of having cut 222 that is easy to just can to make crossbeam 206a than the crossbeam 206c of existing example.In addition, the height of the portion of having cut 222 is whole to be improved if make, even make under the situation of crossbeam 206a at the parts of using the panel material punch forming thinner than the 204a of frame portion to form, also can similarly guarantee the rigidity at the bending of crossbeam 206a.
In addition, because crossbeam 206a is that split punch forming thereby punching formation property are good, so the opening that can be formed for reducing weight at the bottom 224 and upper bend portion 225 places of beam portion 221 with comparalive ease.Though the situation of the perforate that is formed for installing parts such as rain brush motor at upper bend portion 225 places of crossbeam 206a is also arranged, because punching formation property is good, so all can in the perforation of any position.Such as, on crossbeam 206a, for rain brush motor etc. is installed, can be in advance welded nut of fixing usefulness etc. be welded in the upper bend portion 225 of crossbeam 206a.
Among the Hatchback door structure 201a of present embodiment (with reference to figure 9) among the crossbeam 206a of employed wainscot 202a, punch forming direction during shaping crossbeam 206a (below, be called " pressing direction ") and the direction α that has a certain degree perpendicular to the face of a pair of weld part 223.By Figure 11 (b) as can be known, the angled α of vertical direction of the face of the pressing direction of crossbeam 206a and weld part 223.Therefore, the face with a pair of weld part 223 is not vertical by the formed face of having cut portion 222 of punch forming.When the Hatchback door structure 201a that will comprise wainscot 202a was mounted to vehicle V, Hatchback door structure 201a was the center rotation with the hinge 214 that Hatchback door structure 201a is installed.At this moment, parallel for the face that makes the portion of having cut 222 with the tangential direction of the rotational circle of rear door 201, make pressing direction with respect to the angled α of the vertical direction of the face of a pair of weld part 223.
Figure 12 is the A direction view (with reference to Figure 10) of employed wainscot 202a in the present embodiment.Shown in Figure 11 (b), the vertical direction angulation α of the face of the pressing direction of crossbeam 206a and a pair of weld part 223,223 is just in time corresponding to face and the center of crossbeam 206a and line 1 angulation of hinge 214 of a pair of weld part 223,223.According to this corresponding relation, the hinge 214 that the pressing direction of crossbeam 206a is parallel to wainscot 202a is the rotational circle tangential direction of the rear door at center.
When closing rear door, Hatchback door structure 201a is subjected to the effect (with reference to figure 9 and Figure 11) of power on above-mentioned rotational circle tangential direction.Like this, on Hatchback door structure 201a, produce vibration.But, as mentioned above, parallel by the pressing direction that makes crossbeam 206a with the rotational circle tangential direction of Hatchback door structure 201a, utilize the rigidity of the portion of having cut 222 (with reference to Figure 11) of the crossbeam 206a parallel with above-mentioned rotational circle tangential direction, can suppress above-mentioned vibration effectively.
Among the wainscot 202c of existing example shown in Figure 15, because crossbeam 206c and the moulding of the 204c of frame portion integrated punching, the pressing direction of 204c of frame portion and crossbeam 206c is always identical.But the pressing direction of the crossbeam 206a of present embodiment is not consistent with the pressing direction of wainscot 202a (with reference to Figure 12).Among the present invention,, thereby can determine the pressing direction of two parts independently because crossbeam 206a is the parts with wainscot 202a split.
Because crossbeam 206a is the parts with the 204a of the frame portion split of wainscot 202a, so, the thickness of the plate of crossbeam 206a can be arranged to the different thickness with the 204a of frame portion for above-mentioned purposes such as lighting.In addition, the material of crossbeam 206a also can be selected the different material with the 204a of frame portion for use.
The bight 212a (with reference to Figure 10) that is welded about crossbeam 206a and the 205a of window frame portion of wainscot 202a compares explanation with the bight 212c of the wainscot 202c of itself and existing example shown in Figure 15.Figure 13 (a) is the B portion enlarged drawing of the Figure 10 that is welded with crossbeam of the wainscot of present embodiment.Figure 13 (b) is the D portion enlarged drawing of the Figure 15 that is welded with crossbeam of the wainscot of comparative example shown in Figure 15.As can be known, under the situation of the wainscot 202a of present embodiment, crossbeam 206a roughly meets at right angles with the 205a of window frame portion and installs from Figure 13 (a).On the other hand, under the situation of the wainscot 202c of Figure 13 (b) comparative example, because crossbeam 206c and the moulding of the 205c of window frame portion integrated punching, bight 212c needs to be provided with to a certain degree above R value in order to ensure punching formation property.Like this, just the peristome 208a than the wainscot 202a of present embodiment is little with peristome 208c for the window glass of its wainscot 202c.
In the Hatchback door structure 201a of present embodiment under the situation of employed wainscot 202a, because crossbeam 206a is the parts of split, so the height L1 that cuts wall 211a of wainscot 202a (determines with reference to the Figure 13 (a) and the maximum height L3 that Figure 10) can be independent of the portion of having cut 222 (with reference to Figure 11) of crossbeam 206a.On the other hand, for comparative example (and Figure 15) with reference to Figure 13 (b), because crossbeam 206c is restricted by integrally formed thereby punching formation property, the height L2 that has cut wall 211c the 204c of frame portion and crossbeam 206c this aspect two all because of punch forming is restricted, can only be under certain upper limit height Lc (not shown).
And under the situation of wainscot 202a because crossbeam 206a is split with respect to the 204a of frame portion, thus with the wainscot 202c of existing example to compare punching formation property good.Therefore, can make with comparalive ease cut wall 211a height L1 than the upper limit height Lc height of having cut wall 211c.Therefore, as required, can improve the height L1 that has cut wall 211a, that is, increase the inward-outward direction breadth of section of Hatchback door structure 201a, thereby improve the rigidity of the 204a of frame portion that constitutes wainscot 202a.
Next, the formation based on the Hatchback door structure 201a of above-mentioned present embodiment describes its technique effect.
Under the situation of the rear door 1a of present embodiment structure, the pressing direction that can be independent of wainscot 202a decides the pressing direction of the crossbeam 206a of wainscot 202a.Therefore, as mentioned above, compare, by selecting the pressing direction of crossbeam 206a, can effectively be suppressed to close the door vibration when the rear door with existing example.
In the Hatchback door structure 201a of present embodiment, under the situation of employed wainscot 202a,, thereby compare the punching formation property that has improved wainscot 202a with existing example owing to crossbeam 206a is mounted with separate form.Therefore, the height of having cut wall 211a of the 204a of frame portion of wainscot 202a can be provided with highlyer than the height of having cut wall 211c of the wainscot 202c of existing example.Thus, can improve the rigidity of wainscot 202a.
In the Hatchback door structure 201a of present embodiment under the situation of employed wainscot 202a, shown in Figure 13 (a), the 205a of window frame portion of crossbeam 206a and the 204a of frame portion engages in rectangular mode roughly as mentioned above like that.Therefore, compare, enlarged window glass peristome 208a, improved back visibibility thus with the existing example that as shown in Figure 15 crossbeam 206c and the 205c of window frame portion of the 204c of frame portion are integrally formed.
In the Hatchback door structure 201a of present embodiment, under the situation of employed wainscot 202a,, thereby thereby can make its change of shape effectively improve the rigidity of wainscot 202a because crossbeam 206a is the parts (with reference to Figure 10) of split with respect to the 204a of frame portion.In addition, as required, make the thickness ratio frame 204a of portion of crossbeam 206a thinner or thicker, just can realize the lighting of wainscot 202a or the purpose that rigidity improves.And the material of crossbeam 206a also can change with respect to the 204a of frame portion.Such as, for the purpose of lighting, crossbeam 206a can be an aluminium alloys system.
In addition, because crossbeam 206a is the parts with the 204a of frame portion split, thereby the panel material of the window opening portion that stamping-out gets off is bigger by the punch forming of the 204a of frame portion.Therefore, can utilize the panel material that gets off by punching press institute stamping-out to make other parts.
Under the situation of the Hatchback door structure 201a of present embodiment, smallclothes parts such as nut can also be assembled in advance the crossbeam 206a of split.Such as, the welded nut that is used to install the rain brush motor can be welded on crossbeam 206a in advance.So, can reduce the number of spare parts of welding, seek the simplification of welding sequence with plate.
Embodiments of the present invention are not limited to the content that embodiment limited of above-mentioned explanation.Can also be without departing from the spirit and scope of the present invention each component parts of embodiment be changed.Might not be parallel fully such as, the pressing direction of crossbeam 206a as shown in figure 12 with the tangential direction of the rotational circle of rear door.In addition, the 204a of frame portion of wainscot 202a being carried out following change is also included within the technical scope of the present invention.
(the 5th embodiment)
Figure 14 is the stereogram that has carried out the wainscot of reinforcement by employed V font reinforced bulkhead in the present invention's the 5th embodiment.In this embodiment, the top of the 204b of frame portion of wainscot 202b is identical with the 204a of frame portion of the wainscot 202a of Figure 10.But, to locking installation portion 210, be provided with V font reinforced bulkhead portion 215 from two bights being arranged on the window frame portion 205b lower end on the 204b of frame portion, on the both sides of V font reinforced bulkhead portion 215, be provided with peristome 216a, 216b.
In the Hatchback door structure that uses wainscot 202b shown in Figure 14, as mentioned above, because the crossbeam 206b of split engages, so the punching formation property of the 204b of frame portion is good.Thus, by having improved the V font reinforced bulkhead portion 215 of having cut wall 211b height, can make wainscot 202b have enough rigidity.Therefore, under the situation of the Hatchback door structure that has used wainscot 202b shown in Figure 14, the whole technique effects that not only possessed above-mentioned Hatchback door structure 201a, and the effect by peristome 216a, 216b, especially also possessing further technique effect aspect the lighting of Hatchback door structure.
