[Figure 5]A schematic cross-sectional view along the VV line in Figure 1. [Figure 6] A magnified view of a portion of Figure 5. [Modes for carrying out the invention]
[0009] A fixing structure 30 for a display unit 20 fixed to the instrument panel (decorative panel) 18 of a vehicle 10, according to one embodiment of the present invention, will be described with reference to Figures 1 to 6.
[0010] Figure 1 shows a schematic view of the front side of the vehicle 10 as seen from the top (roof side) of the vehicle 10. In Figure 1, the multiple first brackets 34 and the male screws 90 are not shown.
[0011] Figure 1 uses an XYZ Cartesian coordinate system. In Figure 1, the top of the paper is the front side of the vehicle 10 along the +Y axis, the right side is the right side along the +X axis, the left side is the left side along the -X axis, and the bottom is the rear side along the -Y axis. Note that in Figure 1, only the parts of the vehicle 10 used for explanation in the embodiment are shown, and other parts are omitted from the illustration.
[0012] Vehicle 10 here can be a so-called engine-powered vehicle, and can be any of the following: EV (Electric Vehicle), HEV (Hybrid Electric Vehicle), PHV (Plug-in Hybrid Vehicle), FCV (Fuel Cell Vehicle), etc.
[0013] As shown in Figure 1, the vehicle 10 has, for example, a left side member 12, a right side member 14, and a cylindrical beam 16 connecting the left side member 12 and the right side member 14 at the front of the vehicle 10. The beam 16 is fixed to the left side member 12 and the right side member 14 with bolts or the like (not shown). The beam 16 may be cylindrical or a suitable polygonal cylindrical shape. The instrument panel section 18 is located on the rear side (cab side) relative to the beam 16.
[0014] For this reason, a fixed structure 30 of the display unit 20 is fixed to the beam 16 on the cab side (rear side) with respect to the beam 16. And a display unit 20 visible to the occupant of the vehicle 10 is fixed to the fixed structure 30. In the present embodiment, although the display unit 20 will be described as being arranged at the center in the width direction of the instrument panel portion 18, it may be displaced to the right side or may be displaced to the left side.
[0015] Here, FIG. 2 shows a schematic perspective view of the display unit 20 as viewed from the rear side of the display unit 20. In FIG. 2, illustration of male screws for fixing a plurality (two) of first brackets 34 to the back surface (rear surface) 22b of the display portion 22 is omitted.
[0016] FIG. 3 is a schematic view of the fixed structure 30 of the display unit 20 as viewed from the cab side and from above. FIG. 4 is a schematic view of the fixed structure 30 of the display unit 20 as viewed from the cab side and from the upper left side with respect to FIG. 3.
[0017] FIG. 5 is a schematic cross-sectional view taken along the line V-V in FIG. 1. FIG. 6 is a view showing an enlarged part of FIG. 5.
[0018] As shown in FIGS. 1 and 2, the display unit 20 has a display portion 22 having a display screen 22a and a housing portion 24 provided on the back surface 22b side of the display portion 22. In the present embodiment, when the display unit 20 is viewed from the display screen 22a side, the display portion 22 is formed to have a size such that the housing portion 24 is hidden and not visible.
[0019] The display unit 20 is oriented with respect to the vehicle 10 such that the display screen 22a faces the cab side (rear side), and the housing portion 24 is arranged on the front side with respect to the display portion 22. If the display screen 22a is planar, it is preferable that the normal direction of the display screen 22a is directed to the rear side and upward from the horizontal direction.
[0020] As shown in FIG. 2, for example, among the display unit 22, on the side opposite to the display screen 22a, at the upper part of the back surface 22b of the display unit 22, there are a plurality (for example, two) of first brackets 34 to be described later, which are fixed while being spaced apart left and right. Therefore, the upper side of the display unit 22 is fixed to the instrument panel base 32 on the vehicle 10 side at a plurality of points (for example, two points) spaced apart left and right. The position where the first bracket 34 is fixed is preferably the upper part of the back surface 22b of the display unit 22, but it may be the left and / or right edge portions of the display unit 22 instead of the back surface 22b of the display unit 22 shown in FIG. 2.
[0021] The fixing structure 30 of the display unit 20 shown in FIGS. 1 to 4 includes an instrument panel base (hereinafter, mainly referred to as an IP base) 32, a first bracket 34, a second bracket 36, and a frame member 38.
[0022] The IP base 32 has its front end fixed to the beam 16 by bolts (not shown). And the IP base 32 extends from the beam 16 toward the rear side (cab side). And the IP base 32 includes a rectangular frame-shaped frame (vehicle-side frame) 40 into which the housing portion 24 of the display unit 20 is fitted.
[0023] <00
[0025] The IP base 32 has an opening through which the housing portion 24 on the back (rear side) 22b side of the display unit 20 is inserted. The opening is formed, for example, by the flat portions 42a, 42b, extension plate 46, upper projection 48a, and lower projection 48b of the rectangular frame 42, which will be described later. The housing portion 24 of the display unit 20 is then placed within the opening of the IP base 32.
[0026] As shown in Figures 5 and 6, the base 44 has a first fixing surface 44a for fixing the first to third parts 66 of the first bracket 34 (described later), and a second fixing surface 44b for fixing the second bracket 36. The normal direction of the first fixing surface 44a faces the cab side (-Y axis direction and +Z axis direction) and is directed above the upper end of the display unit 22. The normal direction of the second fixing surface 44b faces the opposite direction to the normal direction of the first fixing surface 44a, that is, it faces the front side and is directed downward from the horizontal direction.
[0027] As shown in Figures 3 to 6, the extension plate 46 supports the first and second portions 64 of the first bracket 34, which will be described later.
[0028] As shown in Figures 3 and 4, there is a gap between the protrusions 48a, 48b and protrusion 50a, and a gap between the protrusions 48a, 48b and protrusion 50b, forming the flat portions 42a, 42b on the rear side of the rectangular frame 42. The protrusions 50a, 50b project toward the cab side relative to the protrusions 48a, 48b. Therefore, if the back surface 22b of the display portion 22 of the display unit 20 is flat, it may come into contact with the protrusions 50a, 50b which are spaced further apart horizontally than the protrusions 48a, 48b which are spaced further apart vertically. On the other hand, it is preferable that the back surface 22b of the display portion 22 of the display unit 20 be spaced further toward the cab side relative to the protrusions 48a, 48b which are spaced further apart vertically.
[0029] The first bracket 34 shown in Figures 2, 5, and 6 is formed, for example, by pressing or other processing on a single metal plate. The first bracket 34 has a first-first portion (first part) 62 which is fixed to, for example, the upper part of the back surface 22b of the display unit 22 with screws (not shown), a first-second portion 64 which is integrally formed with the first-first portion 62 and extends from the first-first portion 62 toward the front when the display unit 20 is fixed to the IP base 32 described later, and a first-third portion (second part) 66 which is integrally formed with the first-second portion 64 and, when fixed to the IP base 32, the normal direction of the surface opposite to the fixing surface to the IP base 32 faces toward the cab side and is directed toward above the upper end of the display unit 22.
[0030] The first-first portion 62 is formed to be tightly attached to the back surface 22b of the display unit 22 using screws (not shown). This ensures that the first-first portion 62 is securely fixed to the back surface 22b of the display unit 22.
[0031] The first-second portion 64 extends forward, bent by, for example, an angle α relative to the first-first portion 62. The angle α is preferably, for example, 90°.
[0032] The first to third portion 66 is bent upward by, for example, an angle β relative to the front end of the first to second portion 64. The angle β depends on the angle at which the first to second portion 64 is inclined with respect to the horizontal plane, but it is formed to extend forward and upward relative to the front end of the first to second portion 64. The angle β is preferably 90° or more and less than 180°. The angle β is more preferably less than 135°.
[0033] Then, through holes (screw holes) 67 are formed in the first to third parts 66, which are fixed to the base 44 of the IP base 32. Similarly, through holes (screw holes) 45 are formed in the base 44 of the IP base 32, through which the body and threaded portion of the screw 90 pass.
[0034] Preferably, the central axis (virtual line) of the through-hole 67 in the first-third portion 66 of the first bracket 34 is coaxial with the central axis of the through-hole 45 of the base 44 and the central axis of the screw hole (through-hole) 73 of the second-first portion 72 of the second bracket 36, which will be described later. Furthermore, preferably, the central axis (virtual line) of the through-hole 67 in the first-third portion 66 of the first bracket 34 does not intersect with the upper end of the components of the display unit 20 and passes above the components of the display unit 20. For this reason, the bending angle β of the first bracket 34 is set so that when the first bracket 34 is fixed to the base 44, the head of the screw (fastening member) 90 faces the cab side (rear side), that is, the inside of the vehicle interior.
[0035] The second bracket 36 shown in Figures 3 to 6 is formed, for example, by pressing or other processing on a single metal plate. The second bracket 36 is fixed to the second fixing surface 44b on the back side of the base 44 of the IP base 32.
[0036] The second bracket 36 has a second-first portion (third portion) 72, a second-second portion 74 integrally formed with the second-first portion 72, a second-third portion 76 integrally formed with the second-second portion 74, and a second-fourth portion (fourth portion) 78 integrally formed with the second-third portion 76.
[0037] The second-first portion 72 has a screw hole 73 which is fixed by a screw 90 to the second fixing surface 44b on the back side of the base 44 of the IP base 32. The inner circumferential surface of the screw hole 73 is cut with an internal thread into which the screw 90 is screwed. The diameter of the screw hole 73 is preferably smaller than the through hole 45 of the base 44 and the through hole 67 of the first-third portion 66.
[0038] Section 2-2 74 is bent at an angle γ (for example, about 90°) relative to section 2-1 72. Furthermore, section 2-2 74 extends forward and downward relative to section 2-1 72.
[0039] The second-third portion 76 is bent at an angle δ (for example, about 135°) relative to the second-second portion 74. The second-third portion 76 extends forward and downward relative to the second-second portion 74. The angle δ is preferably such that the tip of the screw 90 does not interfere. The angle δ is preferably within the range of 120° or more and 150° or less.
[0040] The second-fourth portion 78 is bent at an angle ε (for example, about 110°) relative to the second-third portion 76. The second-fourth portion 78 extends forward and downward relative to the second-third portion 76. The direction in which the second-fourth portion 78 extends is, for example, parallel to the upper surface of the housing portion 24 of the display unit 20. It is preferable to set the angle ε such that the direction in which the second-fourth portion 78 extends is parallel to the upper surface of the housing portion 24 of the display unit 20.
[0041] The frame member 38 shown in Figures 1, 3 to 6 is fixed to the second-fourth portions 78 of the second bracket 36, for example, by welding.
[0042] As shown in Figures 3 and 4, the frame member 38 has a horizontal member 82 extending in the left-right direction (horizontal direction), a pair of arms 84a and 84b extending downward and towards the rear from both ends of the horizontal member 82, and fixing plates 86a and 86b provided on the arms 84a and 84b.
[0043] Of the pair of arms 84a and 84b, the left arm 84a has a fixing plate 86a extending to the left at its rear end. The fixing plate 86a is fixed to the rear flat surface 42a of the rectangular frame 42 of the frame 40 by screws 92 from the rear side (from the -Y axis direction toward the +Y axis direction). Of the pair of arms 84a and 84b, the right arm 84b has a fixing plate 86b extending to the right at its rear end. The fixing plate 86b is fixed to the rear flat surface 42b of the rectangular frame 42 of the frame 40 by screws 92 from the rear side (from the -Y axis direction toward the +Y axis direction).
[0044] Therefore, the frame member 38 is welded to the second-to-fourth portion (fourth portion) 78 of the second bracket 36 and fixed to the IP base 32 from the rear side of the vehicle 10 with screws 92.
[0045] Furthermore, a projection 52a is formed on the left side of the frame 40's protrusion 50a, projecting to the right. The projection 52a sandwiches a fixing plate 86a between itself and the flat surface 42a of the rectangular frame 42. This restricts the forward and backward movement of the frame member 38 relative to the IP base 32. Additionally, a projection 52b is formed on the right side of the frame 40's protrusion 50b, projecting to the left. The projection 52b sandwiches a fixing plate 86b between itself and the flat surface 42b of the rectangular frame 42. This restricts the forward and backward movement of the frame member 38 relative to the IP base 32.
[0046] Then, screws 90 are placed in the through holes 67 of the first-third portions 66 of the first bracket 34, the through holes 45 of the base 44 of the IP base 32, and the screw holes 73 of the second-first portion 72 of the second bracket 36, and the screws 90 are screwed in to fix the first bracket 34, the IP base 32, and the second bracket 36.
[0047] Therefore, the display unit 20, which is fixed to the first bracket 34, is fixed to the fixing structure 30, which includes the IP base 32.
[0048] In this embodiment, the normal direction of the first fixing surface 44a faces the cab side and is directed upward above the upper end of the display section 22. The normal direction of the second fixing surface 44b faces the opposite direction to the normal direction of the first fixing surface 44a, that is, it faces the front side and is directed downward above the horizontal direction. Therefore, when fastening the screws 90, tools such as screwdrivers can not interfere with the display unit 20, and the screws can be securely fastened through the through holes 67 in the first-third portions 66 of the first bracket 34 and the through holes 45 in the base 44 to the screw holes 73 in the second-first portion 72 of the second bracket 36.
[0049] In this embodiment, a first bracket 34, formed from a metal plate fixed to the back (rear surface) 22b of the display unit 22, is fastened to a structural component of the IP base 32 with screws 90. The display unit 20 according to this embodiment is not merely engaged, but is firmly fixed to the IP base 32. Since the component of the IP base 32 to which the screws 90 are fastened is a second bracket 36 formed from a metal plate, a high holding force of the display unit 20 to the IP base 32 can be maintained.
[0050] Furthermore, suppose that the vehicle 10 according to this embodiment is struck from the rear, and an impact is input to the rear of the vehicle 10. This impact is transmitted to the beam 16 extending horizontally to the front portion of the vehicle 10 via the structure of the left side member 12 and the right side member 14 of the vehicle 10. From the beam 16, the impact is then transmitted to the display unit 20 through the IP base 32 and the first bracket 34. At this time, the display unit 20 may try to move toward the occupant side (rear side) due to inertia.
[0051] In this embodiment, even if an impact is applied from the rear of the vehicle 10, the display unit 20, which is fixed to the IP base 32 via the first bracket 34 by the screw 90, is prevented from moving.
[0052] Therefore, the fixation of the IP base 32 to the beam 16 is prevented from being released, and the fixation of the base 44 of the IP base 32 to the second-first portion 72 of the second bracket 36, and the fixation of the first-third portions 66 of the first bracket 34 to the base 44 of the IP base 32 are prevented from being released. As a result, the display unit 20 is prevented from moving toward the occupant relative to the IP base 32.
[0053] Furthermore, the fixing plate 86a of the frame member 38 is fixed to the rear flat portion 42a of the rectangular frame 42 by screws 92, and the fixing plate 86a of the frame member 38 is prevented from moving toward the occupant side beyond the projection 52a. Also, the fixing plate 86b of the frame member 38 is fixed to the rear flat portion 42b of the rectangular frame 42 by screws 92, and the fixing plate 86b of the frame member 38 is prevented from moving toward the occupant side beyond the projection 52b. As a result, when an impact is input from the rear of the vehicle 10 and the impact is input to the second bracket 36 through the IP base 32, the fixing plates 86a and 86b of the frame member 38 are prevented from pushing the back surface 22b of the display unit 22 toward the occupant side.
[0054] Therefore, according to this embodiment, it is possible to provide a fixing structure 30 for the display unit 20 to the instrument panel base 32 of the vehicle 10, and a vehicle 10 having such a fixing structure 30, which can prevent the display unit 20 from falling towards the occupant due to inertia when the vehicle 10 is hit, for example, from the rear of the vehicle 10 and an impact is input to the vehicle 10.
[0055] In the embodiment described above, an example was described in which the screw hole 73 of the second-first portion 72 of the second bracket 36 is formed as a female screw. For example, the screw hole 73 may be a through hole through which the threaded portion of a screw 90 passes. In this case, the screw 90 may be formed as a bolt, and the threaded portion of the screw 90 may be fastened to a nut (not shown). For this reason, the second-first portion (third portion) 72 of the second bracket 36 may be formed as a female screw portion that is fixed to the base and the first bracket 34 by a male screw 90. The female screw portion may be the female screw of the screw hole 73 of the second bracket 34, or a nut. For this reason, a simple nut may be used instead of the second bracket 36.
[0056] It should be noted that the present invention is not limited to the embodiments described above, and can be modified in various ways during implementation without departing from its essence. Furthermore, each embodiment may be combined as appropriate, and in that case, the combined effects can be obtained. Moreover, the above embodiments include various inventions, and various inventions can be extracted by selecting combinations from the multiple constituent elements disclosed. For example, if the problem can be solved and effects obtained even if some constituent elements are deleted from all the constituent elements shown in the embodiment, then the configuration with these deleted constituent elements can be extracted as an invention.
