Summary of the Invention
Problems to be Solved by the Invention
[0005] By the way, the roof panel is an outer panel of the vehicle. That is, the roof panel has a design surface. In order to facilitate shape processing, the roof panel has a lower strength than the skeletal members and reinforcing members. By supporting the antenna module on such a roof panel, there is a risk that the support of the antenna module becomes unstable.
[0006] Therefore, this specification discloses a vehicle superstructure that can support the antenna module more stably than conventional structures. [Means for solving the problem]
[0007] This specification discloses a vehicle superstructure comprising a roof panel, a roof reinforcement, and an antenna module. The roof panel is positioned above the passenger compartment. The roof reinforcement extends in the vehicle width direction and fastens to the roof panel. The antenna module is planar. Furthermore, the roof reinforcement includes a recess in which the antenna module is housed.
[0008] According to the above configuration, the antenna module is supported by the reinforcing component, the roof reinforcement. [Effects of the Invention]
[0009] The vehicle superstructure disclosed herein is capable of supporting the antenna module more stably than conventional structures. [Brief explanation of the drawing]
[0010] [Figure 1] This is a plan view of the vehicle. This vehicle is equipped with the vehicle superstructure according to this embodiment. [Figure 2] This is a cross-sectional view AA of Figure 1. This cross-sectional view illustrates the structure around the antenna module. [Modes for carrying out the invention]
[0011] The vehicle superstructure according to this embodiment will be described below with reference to the drawings. The shapes, materials, quantities, and numerical values described below are illustrative examples for illustrative purposes and can be appropriately changed according to the specifications of the vehicle superstructure. In addition, in all drawings below, equivalent elements will be denoted by the same reference numerals.
[0012] Furthermore, Figures 1 and 2 use a Cartesian coordinate system consisting of the FR axis, RW axis, and UP axis. The FR axis is the longitudinal axis of the vehicle, with the front of the vehicle as the positive direction. The RW axis is the width axis of the vehicle, with the right side of the vehicle as the positive direction. The UP axis is the vertical axis of the vehicle, with the upward direction as the positive direction. The position and direction of each component are explained using this Cartesian coordinate system.
[0013] Figure 1 shows an example of a plan view of vehicle 10. This vehicle 10 is equipped with the vehicle superstructure according to this embodiment. Figure 2 shows an example of cross-section AA of Figure 1. A roof (ceiling) is positioned above the passenger compartment. The roof includes solar glass 20, a resin cover 22, and a roof panel 40.
[0014] The vehicle superstructure according to this embodiment includes the solar glass 20, resin cover 22, and roof panel 40 described above. Furthermore, the vehicle superstructure includes a roof reinforcement 30 and an antenna module 50.
[0015] Solar glass 20 occupies the majority of the roof. Solar glass 20 is a laminate made by stacking sheet glass on top of a solar panel. For example, the dimensions of the solar glass 20 are determined so that it covers more than 80% of the roof.
[0016] A resin cover 22 is provided at the rear end of the solar glass 20. The antenna module 50 is positioned so as to be covered by the resin cover 22. Referring to Figures 1 and 2, the antenna module 50 is a so-called planar type. For example, the antenna module 50 is composed of a rectangular box. The antenna module 50 is a communication device for using ITS services such as GPS, VICC, and ETC.
[0017] For example, the antenna module 50 is disposed at the center in the vehicle width direction. Further, the antenna module 50 is covered with the resin cover 22. A non-metallic resin cover 22 is used so as not to interfere with the transmission and reception by the antenna module 50. Also, referring to FIG. 2, the exposed surfaces of the resin cover 22 are set to the same height as the exposed surface of the solar glass 20, respectively.
[0018] The roof panel 40 is disposed below the solar glass 20 and the resin cover 22. The roof panel 40 is made of sheet metal such as aluminum. As shown by the dashed line in FIG. 1, the roof panel 40 has a frame shape in plan view. Referring to FIG. 2, a back door panel 24 is disposed behind the roof panel 40.
[0019] As a reinforcing part of the roof, a roof lien force 30 is provided. The roof lien force 30 extends in the vehicle width direction. Both ends in the vehicle width direction of the roof lien force 30 are connected to the roof panel 40 and a pair of roof side rails not shown. The roof side rails are skeletal parts of the passenger compartment.
[0020] The roof lien force 30 is a reinforcing part that transmits the load when a load in the vehicle width direction is input to the passenger compartment. For example, the roof lien force 30 is made of a high-tensile steel sheet. That is, the roof lien force 30 has higher strength than the roof panel 40.
[0021] Along the vehicle longitudinal direction, the roof lien force 30 extends from the rear end portion of the solar glass 20 to the flange 42 of the roof panel 40. That is, the roof lien force 30 is disposed below the rear end portion of the solar glass 20 and the resin cover 22.
[0022] Referring to FIG. 2, the UP-FR cross section of the roof lien force 30 has a concavo-convex shape. For example, a downwardly convex cross-sectional hat structure 32 is formed in the roof lien force 30. The cross-sectional hat structure 32 extends, for example, over the entire length in the vehicle width direction.
[0023] The solar glass 20 and the resin cover 22 are abutted against the support portion 34 that contacts the flange of the cross-sectional hat structure 32. For example, the support portion 34 and the solar glass 20 are adhered by an adhesive 52A. Also, the support portion 34 and the resin cover 22 are adhered by an adhesive 52B.
[0024] The roof reinforcement 30 includes a recess 36 behind the support portion 34. The recess 36 is recessed below the support portion 34 and the flange 38. An antenna module 50 is accommodated in this recess 36. For example, a clip (not shown) is adhered to the lower surface of the antenna module 50. Further, fastening holes are drilled in the bottom plate of the recess 36. The clip of the antenna module 50 is inserted into these fastening holes. Thereby, the antenna module 50 is supported by the roof reinforcement 30. The depth of the recess 36 is determined to be approximately the same as the thickness of the antenna module 50.
[0025] Referring to FIGS. 1 and 2, for example, the recess 36 is provided only in the central portion in the vehicle width direction, unlike the cross-sectional hat structure 32. The dimension of the recess 36 in the vehicle width direction is determined to be a value obtained by adding a predetermined margin to the dimension of the antenna module 50 in the vehicle width direction. For example, the dimension of the recess 36 in the vehicle width direction is determined within a range of 1.1 times or more and 1.5 times or less the dimension of the antenna module 50 in the vehicle width direction.
[0026] Furthermore, a multi-stage flange 38 is provided behind the recess 36. The flange 38 is overlapped with the flange 42 of the roof panel 40. The flanges 38 and 42 are fastened with bolts and nuts, for example. Further, the flange 38 and the resin cover 22 are adhered by an adhesive 52C.
[0027] As described above, in the vehicle upper structure according to the present embodiment, the recess 36 is provided in the roof reinforcement 30. And the antenna module 50 is accommodated in this recess 36. By the roof reinforcement 30, which is a reinforcing member, supporting the antenna module 50, the support is more stable compared to the case where the roof panel 40 supports the antenna module 50.
[0028] In the conventional structure, the antenna module 50 was mounted on a plate, and that plate was fixed to the roof panel. In contrast, in the vehicle superstructure according to this embodiment, the antenna module 50 is housed in a recess 36 of the roof reinforcement 30. Therefore, the plate on which the antenna module 50 was mounted is omitted. In other words, the number of parts is reduced compared to the conventional structure. [Explanation of symbols]
