Description

Technical Field

[0001] The technology disclosed in this specification relates to a vehicle door. Background Art

[0002] Japanese Patent No. 3133810 discloses a connection structure between a corner member of a vehicle door and a weather strip. Summary of the invention

[0003] There is a case where the two are connected by engaging the hole of the windshield strip with the protrusion formed on the corner part. When the front end of the protrusion contacts the back of the door trim, the height direction position of the upper surface of the door trim at the door waist will move upward due to the presence of the protrusion. The freedom of appearance design will decrease.

[0004] A vehicle door of one embodiment of the present disclosure includes a door panel. The vehicle door includes a corner member disposed at a door waist portion of the door panel and having a protrusion. The vehicle door includes a windshield strip disposed along an outer peripheral edge of the door panel and having a hole portion engaged with the protrusion. The vehicle door includes a door interior disposed in a manner covering the corner member. The protrusion has a hollow structure having an outer peripheral side wall. An opening portion is formed in a portion of the outer peripheral side wall.

[0005] In the vehicle door of the scheme disclosed herein, the protrusion has a hollow structure, and an opening is formed in a portion of the outer peripheral side wall. As a result, the compression rigidity of the protrusion can be reduced. As a result, when the front end of the protrusion contacts the back of the door interior, the protrusion can be deformed by applying a compressive force to the protrusion, thereby reducing the height of the protrusion. Since the position of the upper surface of the door interior at the door waist can be lowered, the degree of freedom of appearance design can be increased.

[0006] The front end of the protrusion may be closed. The opening may be connected to a cavity formed inside the protrusion. By such a protrusion shape, the compression rigidity of the protrusion can also be reduced.

[0007] The area of ​​the opening in the region from the middle position between the front end of the protrusion and the base of the protrusion to the front end of the protrusion can be larger than the area of ​​the opening in the region from the middle position to the base of the protrusion. Thus, the compression rigidity of the front end side of the protrusion can be lower than the compression rigidity of the base side. The rigidity of the base can be ensured and compression deformation of the protrusion can be made possible.

[0008] The protrusion may have a cylindrical shape with an open front end. The opening may be a slit formed from the front end of the protrusion toward the base of the protrusion. With such a protrusion shape, the compression rigidity of the protrusion can also be reduced.

[0009] The width of the slit at the front end side of the protrusion may be larger than the width of the slit at the base side of the protrusion. Thus, the compression rigidity of the front end side of the protrusion can be made lower than the compression rigidity of the base side.

[0010] The front end of the slit may not reach the base of the protrusion. Thus, the rigidity of the base can be ensured, thus preventing the protrusion from being damaged.

[0011] The details and further improvements of the technology disclosed in this specification will be described in the following “Detailed Description of the Invention”. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] [Example 1]

[0023] The structure of the side door 1 will be described. Figure 1 A side view of a side door 1 on the front side of a vehicle is shown in FIG. Figure 2 FIG. 1 shows an enlarged perspective view of the vicinity of the corner member 11. Figure 3 Shown in Figure 2 The III-III plane is a plane passing through the center of the protrusion 11p. Figure 1 to Figure 3 The state before assembling the door trim 13 is shown. Therefore, the protrusion 11p is in the state before deformation. Figure 1 to Figure 3 The "Front" of the coordinate system indicates the front direction of the vehicle. "Up" indicates the upper direction of the vehicle. "Left" indicates the "left" when looking from the rear of the vehicle to the front. In the following figures, the meaning of the coordinate system is the same.

[0024] The side door 1 includes a door inner panel 10, a corner member 11, and a weather strip 12. The door inner panel 10 is a steel plate member constituting a door body.

[0025] The corner component 11 is a component disposed on the vehicle rear end side of the door waist portion 10w of the door inner panel 10. The door waist portion 10w is the upper end portion of the door inner panel 10 and is also called a waistline. The corner component 11 has a protrusion 11p. The corner component 11 is made of resin (that is, the corner component 11 is a resin corner component), and can be manufactured, for example, by injection molding.

[0026] exist Figure 4 An enlarged stereoscopic view of the protrusion 11p is shown in FIG. Figure 4 In the figure, the description of the windshield strip 12 is omitted. The protrusion 11p is formed on the upper surface 11u of the corner member 11. The protrusion 11p is formed integrally with the corner member 11. The protrusion 11p has a hollow structure with a side wall 11w on the outer periphery. By forming a front end surface 11t at the front end of the protrusion 11p, the front end is closed. An opening 11a is formed in a part of the side wall 11w. The opening 11a is connected to the cavity formed inside the protrusion 11p. That is, the protrusion 11p has a cylindrical shape with an internal cavity having a transverse hole.

[0027] The windshield strip 12 includes an outer peripheral portion 12p and a connecting portion 12c. The outer peripheral portion 12p is arranged along the outer peripheral edge of the door panel on the inner side of the vehicle. The outer peripheral portion 12p functions as a strip-shaped seal that fills the gap between the vehicle door and the vehicle body. The connecting portion 12c is arranged at the door waist portion 10w in a manner covering a portion of the corner member 11. The connecting portion 12c and the outer peripheral portion 12p are formed integrally from the same material. The thickness of the connecting portion 12c is thicker than that of the outer peripheral portion 12p, and the rigidity is high. The connecting portion 12c includes a hole portion 12h. The hole portion 12h is penetrated by the protrusion 11p, and the hole portion 12h is engaged with the protrusion 11p.

[0028] The assembly process of the side door 1 is described. First, the corner member 11 is assembled to the door inner panel 10. Next, the hole 12h of the connecting portion 12c of the weather strip 12 is engaged with the protrusion 11p of the corner member 11. Figure 3 As shown, the front end surface 11t of the protrusion 11p is in a state of protruding from the upper surface 12u of the connecting portion 12c by a protrusion amount P1.

[0029] Afterwards, if Figure 5As shown, the door trim 13 is installed so as to cover the corner member 11. The door trim 13 is a lining member inside the door chamber. When the door trim 13 is installed, the back surface 13b of the door trim 13 contacts the front end surface 11t. As a result, a compressive force CF is applied to the protrusion 11p.

[0030] Since the protrusion 11p has a hollow structure and an opening 11a is formed in a part of the side wall 11w, the compression rigidity becomes low. Figure 5 As shown in FIG. 1 , the protrusion 11p can be deformed in a manner that the protrusion 11p is buckled in the axial direction. The height of the protrusion 11p can be increased from the height H1 ( Figure 3 ) is reduced to the height H2 after deformation ( Figure 5 As a result, the front end surface 11t of the protrusion 11p can be set to a state where it hardly protrudes from the upper surface 12u of the weather strip 12.

[0031] The effect of Example 1 is described. Figure 6 2 shows the structure of a side door 100 of a comparative example. Figure 6 is with Figure 5 Same cross-sectional view. The protrusion 111p provided on the corner component 111 of the comparative example does not form the opening 11a. Therefore, the compressive rigidity of the protrusion 111p is high. The door interior 13 has an interior upper surface 13u above the door waist 10w. The back surface 13b of the door interior 13 is in contact with the front end surface 111t of the protrusion 111p. The height H12 of the interior upper surface 13u from the upper surface 12u is the sum of the protrusion amount P1 of the protrusion 111p and the thickness T1 of the door interior 13. That is, the interior upper surface 13u will move upward by the protrusion amount P1. On the other hand, in the side door 1 ( Figure 5 ), the protrusion 11p has a hollow structure, and an opening 11a is formed in a part of the side wall 11w. As described above, the height can be lowered by deforming the protrusion 11p, so that the front end surface 11t can be set to a state where it does not protrude from the upper surface 12u. The height H11 of the interior upper surface 13u from the upper surface 12u is not affected by the protrusion 11p. The height H11 ( Figure 5 ) is higher than the height H12 of the interior upper surface 13u of the comparative example ( Figure 6 ) is low. It can increase the degree of freedom in appearance design.

[0032] When assembling the side door 1, Figure 3 As shown in FIG. 1 , the protrusion 11p can be set to a high state with a height H1. The process of engaging the hole portion 12h with the protrusion 11p can be easily performed. In addition, the engaged hole portion 12h can be prevented from falling off during assembly. On the other hand, after the side door 1 is assembled, as shown in FIG. Figure 5As shown, the protrusion 11p can be set to a low state with a height H2. The height of the interior upper surface 13u can be reduced. The simplification of the assembly process and the improvement of the degree of freedom of the appearance design can be achieved at the same time.

[0033] [Example 2]

[0034] exist Figure 7 An enlarged stereoscopic view of the protrusion 211p of Example 2 is shown in FIG. The protrusion 211p has a hollow structure with a side wall 211w on the outer periphery, and has a cylindrical shape with a front end 211t open. In addition, the protrusion 211p has a slit 211s formed from the front end 211t toward the base 211b. In other words, an opening is formed in a part of the side wall 211w through the slit 211s. The front end 211sT of the slit 211s does not reach the base 211b. It should be noted that the other structures in Example 2 are the same as those in Example 1, and therefore the description is omitted.

[0035] The effects of Example 2 are described below. By providing a slit 211s in a portion of the side wall 211w, the compressive rigidity of the protrusion 211p can be reduced. By applying a compressive force CF, the protrusion 211p can be deformed in a manner that it is buckled in the axial direction of the protrusion 211p. Since the height of the protrusion 211p can be reduced, the height of the interior upper surface 13u can be reduced.

[0036] Since the front end 211sT of the slit 211s does not reach the base 211b, the compressive rigidity of the base 211b can be ensured. Thus, it is possible to prevent the base 211b from being damaged and the protrusion 211p from being detached when the compressive force CF is applied. In addition, the compressive rigidity of the front end 211t side can be reduced compared to the base 211b side. The deformation amount near the front end 211t can be increased, so the reduction amount of the height of the protrusion 211p can be sufficiently ensured.

[0037] Although the specific examples of the present invention are described in detail above, they are merely illustrative and do not limit the scope of the present disclosure. The technology disclosed in the present disclosure includes various deformations and changes to the specific examples exemplified above. The technical elements described in this specification or the drawings exert technical usefulness in the form of individual or various combinations, and are not limited to the combination of specific examples. In addition, the technology exemplified in this specification or the drawings can achieve multiple purposes at the same time, and achieving one of the purposes itself has technical usefulness.

[0038] (Variation Example)

[0039] exist Figure 8, a protrusion 311p of a modified example is shown. In the opening portion 311a of the protrusion 311p, the width W1 on the side of the front end 311t of the protrusion 311p is larger than the width W2 on the side of the base 311b of the protrusion 311p. Here, the middle position between the front end 311t and the base 311b is set as MP. The area from the middle position MP to the front end 311t is set as the upper area UA. The area from the middle position MP to the base 311b is set as the lower area LA. Therefore, the area of ​​the opening portion 311a in the upper area UA is larger than the area of ​​the opening portion 311a in the lower area LA. By having such an opening portion 311a, the compressive rigidity on the side of the front end 311t of the protrusion 311p can be reduced compared with the compressive rigidity on the side of the base 311b.

[0040] exist Fig. 9 4 shows a protrusion 411p of a modified example. The protrusion 411p has a slit 411s. In the slit 411s, the width of the protrusion 411p on the side of the front end 411t is W11, and the width of the protrusion 411p on the side of the base 411b is W12. The width W11 is larger than the width W12. By having such a slit 411s, the compression rigidity of the protrusion 411p on the side of the front end 411t can be reduced compared with the compression rigidity of the base 411b side.

[0041] In the present embodiment, the structure of the side door 1 on the front side of the vehicle is described, but the present invention is not limited to this form. The present technology can also be applied to the side door on the rear side of the vehicle.

[0042] In this embodiment, the configuration position of the protrusion is described as the upper surface of the corner member 11, but the present invention is not limited to this mode. The protrusion may also be located on the side of the corner member 11. Thus, the protrusion amount of the door trim 13 toward the vehicle interior can be suppressed, thereby expanding the vehicle interior space.

[0043] In the protrusion 11p ( Figure 4 ) described the case where the opening 11a is one, but the present invention is not limited to this embodiment. The opening 11a may be two or more. Figure 7 ) illustrates a case where there are two slits 211s, but the present invention is not limited to this embodiment. The number of slits 211s may be one, or three or more.

[0044] The opening 11 a and the slit 211 s are examples of an opening.
