Description

  The present invention relates to a vehicle door that includes an inner panel disposed on the inner side of the vehicle and an outer panel disposed on the outer side of the vehicle.

  Since the vehicle door is required to have strength against road surface vibration during traveling, structural strength as a vehicle body component, and strength to support equipment accompanying the expansion of specifications, the panel constituting the vehicle door has high rigidity ( Strength) is required. As a method for improving the rigidity, it is known to form a bead on an inner panel that constitutes a vehicle inner surface of a vehicle door (for example, Patent Document 1). By forming a bead on the inner panel as in Patent Document 1, it is possible to improve the surface rigidity of the inner panel and thus the rigidity of the vehicle door.

Special table 2013-514223 gazette

  Here, in recent years, since the panel area of the vehicle door has been increasing year by year, higher rigidity is required for the vehicle door panel so that the panel surface does not become sticky. Further, since the vehicle door is in a state of being supported by the vehicle body only at the hinge portion in the open state, a structure capable of ensuring rigidity even with a small number of support portions is required. Further, in the closed state of the vehicle door, the vicinity of the peripheral edge contacts the vehicle body. At this time, if the rigidity of the vehicle door is low, the vibration of the vehicle body may propagate due to the propagation of the vibration of the vehicle body, or deformation due to the load from the vehicle body may occur at the contact point with the vehicle body. There is a risk.

  In view of such a problem, the present invention provides a vehicle door that can obtain high surface rigidity in an inner panel that constitutes a surface on the inner side of the vehicle, and thus can improve the rigidity of the entire door. It is aimed.

  In order to solve the above-mentioned problems, a typical configuration of a vehicle door according to the present invention is a vehicle door configured to include an inner panel disposed inside a vehicle and an outer panel disposed outside the vehicle. The inner panel includes an upper door glass opening to which the door glass is attached, a panel surface below the door glass opening, and a plurality of beads bulging inside or outside the vehicle. A horizontal bead extending in the left-right direction along the upper edge of the inner panel, and a pair of left and right vertical beads extending downward from the left and right ends of the horizontal bead along the left and right side edges of the inner panel continuously from the horizontal bead. And a pair of left and right inclined beads that continue from the vertical bead and descend to the center of the panel surface, and the lower ends of the pair of right and left inclined beads are connected to each other.

  According to the above configuration, a pentagonal bead including a horizontal bead, a pair of left and right vertical beads, and a pair of left and right inclined beads is formed in the inner panel. Thereby, since the load loaded in the inner panel can be suitably distributed, it is possible to prevent the occurrence of load concentration and to obtain high rigidity in the inner panel and thus in the vehicle door. Further, by arranging the pair of left and right inclined beads so as to cross the panel surface, it is possible to increase the surface rigidity of the panel surface, and it is also possible to suppress the stickiness of the panel surface.

  The pair of left and right vertical beads extends downward along the left and right sides of the door glass opening, and the pair of left and right inclined beads is formed into a pair of left and right vertical beads starting from the lower corner of the door glass opening. It should be continuous. According to such a configuration, it is possible to improve the rigidity in the vicinity of the door glass opening in the inner panel.

  One or more of the above-mentioned continuous locations of the horizontal beads and the pair of left and right vertical beads, the continuous locations of the pair of left and right vertical beads and the pair of left and right inclined beads, and the connection locations of the lower ends of the pair of left and right inclined beads It is preferable to further include a component mounting surface that is located in the vicinity and to which the vehicle body structural component is mounted. Thereby, the load from the vehicle body structural component attached to the component attachment surface can be propagated to the beads in two directions, and can be suitably distributed over the entire inner panel. Moreover, since the continuous part of a bead has high rigidity, it becomes possible to improve the attachment stability of a vehicle body structural component by making it into a component attachment surface.

  The plurality of beads may further include an inner bead provided in a region surrounded by a horizontal bead, a pair of left and right vertical beads, and a pair of left and right inclined beads and passed between two of the beads. . According to such a configuration, the inner bead functions as a tension rod with respect to the load in the twisting direction with respect to the inner panel, so that it is possible to increase the rigidity against the force in the twisting direction.

  The inner bead has at least one or more bent portions between two continuous beads, and the plurality of beads includes one or more of a horizontal bead, a pair of left and right vertical beads, and a pair of right and left inclined beads. A connection bead for connecting the bead and the bent portion may be further included. As a result, the pentagonal bead made up of the horizontal beads, the pair of left and right vertical beads, and the pair of right and left inclined beads and the inner bead are bridged by the connection beads, so that the reinforcing effect by the beads can be further enhanced. Further, the load distribution direction in the bead is increased, so that it is possible to deal with loads in more load directions.

  The vehicle body structural parts are a vehicle door hinge, a balancer, and a door latch, and the part mounting surface is located in the vicinity of a continuous portion between the horizontal bead and the pair of left and right vertical beads, and the hinge mounting surface to which the vehicle door hinge is mounted. A balancer mounting surface on which a balancer is mounted, which is located in the vicinity of a continuous portion between a pair of left and right vertical beads and a pair of left and right inclined beads, and a door latch which is positioned in the vicinity of a connecting portion between lower ends of the pair of left and right inclined beads. And a door latch mounting surface. According to this configuration, the above-described effects can be obtained on the mounting surfaces of the vehicle door hinge, the balancer, and the door latch.

  ADVANTAGE OF THE INVENTION According to this invention, high surface rigidity can be obtained in the inner panel which comprises the surface inside a vehicle, and by extension, the vehicle door which can improve the rigidity of the whole door can be provided.

It is the figure which observed the door for vehicles concerning this embodiment from the vehicles back side. It is the figure which observed the vehicle door of FIG. 1 from the vehicle front side. It is a figure which shows the distribution direction of the load in the inner panel of FIG.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  FIG. 1 is a diagram of the vehicle door according to the present embodiment observed from the vehicle rear side, and FIG. 2 is a diagram of the vehicle door of FIG. 1 observed from the vehicle front side. In the present embodiment, the back door 100 attached to the rear portion of the vehicle (not shown) is illustrated as the vehicle door. However, the present invention is not limited to this, and the present invention is applied to other vehicle doors. It is also possible to apply.

  The back door 100, which is a vehicle door of the present embodiment, has an outer surface constituted by an outer panel 102 arranged on the vehicle outer side as shown in FIG. 1, and an inner panel 110 arranged on the vehicle inner side as shown in FIG. The inner surface is configured. The outer panel 102 is a member mainly constituting the door design of the back door 100, and the inner panel 110 is a member to which a vehicle body structural component such as a door trim (not shown) is attached.

  In the inner panel 110, a door glass opening 112 to which a door glass 104 (see FIG. 1) is attached is formed in an upper portion, and a panel surface 114 is disposed below the opening. Further, in the present embodiment, as will be described later, a plurality of beads bulging on the inner side of the inner panel 110 are formed. In addition, although this embodiment illustrates and demonstrates the case where a bead bulges to the vehicle inner side, it is not limited to this, It can also be set as the structure bulged to the vehicle outer side. Further, in order to facilitate understanding, in FIG. 2, a plurality of beads are illustrated by hatching.

  As shown in FIG. 2, the inner panel 110 is formed with a lateral bead 122 extending in the left-right direction along the upper edge thereof. From the left and right ends of the horizontal bead 122, a pair of left and right vertical beads 124 (right vertical bead 124a and left vertical bead 124b) extending downward along the left and right side edges of the inner panel 110 continuously from the horizontal bead 122. Is formed. From the pair of left and right vertical beads 124, a pair of left and right inclined beads 126 (right inclined bead 126a and left inclined bead 126b) are formed continuously descending to the center of the panel surface 114. . The pair of left and right inclined beads 126 are connected at the lower ends in the vicinity of the lower edge of the inner panel 110.

  FIG. 3 is a diagram illustrating a load distribution direction in the inner panel 110 of FIG. 2. In order to facilitate understanding, in FIG. 3, the load distribution direction is illustrated by white arrows. In the following description, the right vertical bead 124a and the left vertical bead 124b are referred to as the vertical bead 124 when not distinguished from each other, and the right inclined bead 126a and the left inclined bead 126b are referred to as the inclined beads 126 when not distinguished from each other.

  As described above, the lower ends of the pair of left and right inclined beads 126 are connected in the vicinity of the lower edge of the inner panel 110, so that the inner panel 110 has a substantially pentagonal shape including the horizontal beads 122, the vertical beads 124, and the inclined beads 126. A bead is formed. Thereby, as shown in FIG. 3, the load applied to the upper part of the inner panel in the directions of the arrows 202a and 202b can be propagated by the vertical beads 124 in the directions of the arrows 204a and 204b, that is, downward. Then, the load propagated to the vertical beads 124 can be propagated by the inclined beads 126 in the directions of the arrows 206 a and 206 b, that is, toward the center of the panel surface 114.

  Since the load can be uniformly distributed throughout the inner panel 110 as described above, it is possible to increase the rigidity of the inner panel 110 and thus the entire vehicle door. In addition, by arranging the pair of left and right inclined beads 126 so as to cross the panel surface 114, the surface rigidity of the panel surface 114 can be increased, and the stickiness of the panel surface 114 can be suppressed.

  Furthermore, according to the said structure, the distribution direction of a load becomes another direction in the continuous location of each bead. Thereby, since concentration of the load in the continuous part of each bead can be suppressed, it becomes possible to prevent the damage there and to enhance the reinforcement effect by a bead. In addition, since the load distribution direction is different in the continuous portion of each bead, it takes place when the inner panel 110 receives vibration from a hinge or a latch (both not shown) when the back door 100 is closed. Since the vibration phase can be changed, direct propagation of vibration can be suppressed. Therefore, it is possible to prevent the occurrence of cracks due to resonance, which has been apt to occur in the continuous locations of each bead, and the damage resulting therefrom.

  Here, a hexagonal or octagonal bead having a conventionally known configuration, that is, a vertically symmetrical bead is compared with this embodiment. In a conventional bead, when a compressive load is applied in a direction in which the upper and lower edges (upper and lower sides) of the inner panel 110 are narrowed or a tensile load is applied in a direction in which the inner panel 110 is expanded, a load is applied to the center in the vertical direction of the bead. There was a tendency for damage to occur at the location. On the other hand, since the bead has a pentagonal shape as in the present embodiment, a high strength against a compressive load and a tensile load can be obtained, so that the reinforcement effect of the bead can be sufficiently exhibited. .

  Preferably, the pair of left and right vertical beads 124 are extended downward along the left and right sides of the door glass opening 112, and the pair of left and right inclined beads 126 are left and right starting from the lower corner of the door glass opening 112. It is good to continue to a pair of vertical beads 124. According to such a configuration, it is possible to improve the rigidity in the vicinity of the door glass opening 112 in the inner panel 110.

  As shown in FIG. 2, in the present embodiment, the right vertical bead in the region surrounded by the horizontal bead 122, the pair of left and right vertical beads 124 and the pair of left and right inclined beads 126, that is, in the region of the pentagonal bead. An inner bead 128 is formed between 124a and the left vertical bead 124b. Thereby, the inner bead 128 can function as a tension rod with respect to the load in the twisting direction with respect to the inner panel 110, and the rigidity of the inner panel 110 with respect to the load in the twisting direction can be increased. Therefore, it is possible to suppress the torsion of the vehicle door that tends to occur due to the enlargement of the vehicle door (door panel) and the small number of support points on the vehicle body.

  In the present embodiment, the inner bead 128 is provided with bent portions 128a and 128b between the continuous portions P3 and P4 of the right vertical bead 124a and the left vertical bead 124b. Thereby, the rigidity with respect to the load in the torsional direction described above can be further increased. In the present embodiment, the configuration in which two bent portions are provided on the inner bead 128 is illustrated, but the present invention is not limited to this, and at least one bent portion may be provided.

  Furthermore, in this embodiment, on the panel surface 114 of the inner panel 110, connection beads 130a and 130b for connecting the bent portions 128a and 128b of the inner bead 128 and the connecting portion P5 of the pair of left and right inclined beads 126 are provided. As a result, the pentagonal bead composed of the horizontal beads 122, the pair of left and right vertical beads 124, and the pair of right and left inclined beads 126 and the inner bead 128 are bridged by the connection beads 130a and 130b. It becomes possible to raise.

  Further, by providing the inner bead 128 in the region within the pentagonal bead as described above, the following effects can be obtained. That is, the load propagated to the right vertical beads 124a and 124b as indicated by arrows 204a and 204b in FIG. 3 can be propagated to the panel surface 114 of the inner panel 110 as indicated by arrows 208a and 208b.

  On the other hand, since the pentagonal bead and the inner bead 128 are connected by the connection beads 130a and 130b, the following effects can be obtained. That is, the load propagated to the inner bead 128 as indicated by arrows 208a and 208b is propagated downward as indicated by arrows 210a and 210b, and a pentagonal bead as indicated by arrows 212a and 212b (inclined bead 126 in FIG. 3). Can be propagated to. Thus, it becomes possible to cope with more load directions by increasing the load distribution direction in the bead.

  In the present embodiment, the configuration in which the inner bead 128 is passed between the right vertical bead 124a and the left vertical bead 124b is exemplified, but the present invention is not limited to this. For example, the inner bead 128 may be passed between any two of the horizontal beads 122, the pair of left and right vertical beads 124, and the pair of left and right inclined beads 126.

  Moreover, although the connection bead 130a * 130b illustrated the structure which connected the bending part 128a * 128b of the inner side bead 128 and the connection location P5 of the inclination bead 126 in this embodiment, it is not limited to this. For example, the connection beads 130 a and 130 b may connect beads other than the inclined beads 126, that is, the horizontal beads 122 and the pair of left and right vertical beads 124 and the bent portions 128 a and 128 b of the inner beads 128. Alternatively, the connection beads 130 a and 130 b may connect a portion other than the connection portion of the pentagonal bead and the bent portions 128 a and 128 b of the inner bead 128.

  Here, as described above, high rigidity (strength) is obtained in the vicinity of a portion where a plurality of beads constituting the pentagonal bead are continuous in the inner panel 110. Therefore, in the present embodiment, a plurality of continuous beads P1 and P2 are connected to the horizontal beads 122 and a pair of left and right vertical beads P3 and P4 are connected to a pair of left and right vertical beads 124 and a pair of left and right inclined beads 126. , And a connecting portion P5) between the lower ends of the pair of left and right inclined beads 126 is provided with a component mounting surface to which the vehicle body structural component is mounted.

  In the present embodiment, a vehicle door hinge, a balancer, and a door latch (both not shown) are illustrated as vehicle body structural components. As shown in FIG. 2, in this embodiment, a hinge mounting surface 132, a balancer mounting surface 134, and a door latch mounting surface 136 are provided as mounting surfaces for the vehicle door hinge, balancer, and door latch.

  Specifically, the hinge mounting surface 132 is positioned in the vicinity of the continuous portion P1 and P2 between the horizontal bead 122 and the pair of left and right vertical beads 124, and is mounted with a vehicle door hinge serving as a rotation axis when the back door 100 is opened and closed. It is done. The balancer mounting surface 134 is positioned in the vicinity of the continuous portion P3 / P4 between the pair of left and right vertical beads 124 and the pair of left and right inclined beads 126, and a balancer that holds that state when the back door 100 is open is mounted. . The door latch mounting surface 136 is positioned in the vicinity of the connecting point P5 between the lower ends of the pair of left and right inclined beads 126, and a door latch that fixes the back door 100 when the back door 100 is in the closed state is mounted.

  As in the above configuration, by providing the component attachment surface at the continuous location (connection location) of the beads, the load from the vehicle body structural component attached to the component attachment surface can be propagated to two beads having different dispersion directions. For this reason, this load can be suitably distributed throughout the inner panel 110.

  Moreover, since the connection location of the bead and the component mounting surface are close to each other, the load applied from the vehicle body structural component can be quickly propagated to the bead and thus to the entire inner panel 110. For this reason, it is possible to suppress the concentration of load on the component mounting surface and prevent the component mounting surface from being damaged. Furthermore, by providing a part mounting surface in the vicinity of a continuous portion of a bead having high rigidity, it is possible to improve the mounting stability of the vehicle body structural component, which has been conventionally required to improve the rigidity of the mounting surface. It becomes possible to eliminate the reinforcement of the member.

  In addition, in this embodiment, the structure which arrange | positions a component attachment surface to all the vertices in a pentagon-shaped bead, ie, all the continuous locations (connection location) of a some bead, was illustrated. If the component mounting surface is arranged at all the continuous locations (connection locations) of a plurality of beads as in this embodiment, the high rigidity obtained at such continuous locations can be utilized to the maximum extent, but this is limited to this. is not. For example, the continuous points P1 and P2 between the horizontal beads 122 and the pair of left and right vertical beads 124, the continuous points P3 and P4 between the pair of left and right vertical beads 124 and the pair of left and right inclined beads 126, and the lower ends of the pair of left and right inclined beads 126 A part mounting surface may be arranged in the vicinity of one or more of the connection points P5.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
