Summary of the Invention

Problems to be Solved by the Invention

[0004] In the technology of Patent Document 1, as shown in FIG. 1(c), bolt holes and the like are provided around the opening 116 in the instrument panel 102, and the HUD unit 106 is directly attached to the instrument panel 102. That is, the connection part of the HUD unit 106 is integrally formed with the instrument panel 102. Therefore, it is necessary to separately manufacture the instrument panel 102 for vehicles equipped with the HUD unit 106 and those not equipped with it. However, in order to separately manufacture the instrument panel 102, preparations such as a molding die and a production line are required, which may increase the burden in terms of cost and man-hours.

[0005] In addition, since the HUD unit 106 has a corresponding weight, further improvement in the support rigidity on the instrument panel 102 is desired.

[0006] In view of these problems, the present invention aims to provide a vehicle instrument panel structure that improves the support rigidity of the head-up display and enables the common use of components between vehicles with different specifications. [Means for solving the problem]

[0007] To solve the above problems, a typical configuration of the vehicle instrument panel structure according to the present invention is a vehicle instrument panel structure comprising an instrument panel installed in the front of the passenger compartment and a head-up display positioned on the upper surface of the instrument panel, wherein the instrument panel has an open upper opening formed on its upper surface for housing the head-up display, and the vehicle instrument panel structure further comprises an annular annular support member that is attached to the lower side of the upper surface of the instrument panel, surrounding the upper opening, and to which the head-up display is fixed. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a vehicle instrument panel structure that improves the support rigidity of the head-up display and enables the common use of components between vehicles with different specifications. [Brief explanation of the drawing]

[0009] [Figure 1] This figure shows a vehicle instrument panel structure according to an embodiment of the present invention. [Figure 2] This is a diagram showing the garnish from Figure 1 removed. [Figure 3] Figure 2 is a perspective view of the instrument panel structure as seen from below the front of the vehicle. [Figure 4] Figure 3 is a perspective view of the annular support member as seen from the upper rear of the vehicle. [Figure 5] This diagram shows the instrument panel from Figure 3 with the annular support members and other components removed. [Figure 6] Figure 3 is a cross-sectional view AA of the instrument panel structure. [Figure 7] Figure 2 is a cross-sectional view of the instrument panel structure at the bottom bracket (BB). [Figure 8] This figure illustrates the top opening shown in Figure 2. [Modes for carrying out the invention]

[0010] An instrument panel structure for a vehicle according to one embodiment of the present invention comprises an instrument panel installed in the front of the vehicle compartment and a head-up display positioned on the upper surface of the instrument panel, wherein the instrument panel has an open upper opening formed on its upper surface for housing the head-up display, and the instrument panel structure for a vehicle further comprises an annular annular support member that is attached to the lower side of the upper surface of the instrument panel, surrounding the upper opening, and to which the head-up display is fixed.

[0011] According to the above configuration, by using an annular support member, which is a separate component from the instrument panel, and forming a two-layer structure of the instrument panel and the annular support member to install the head-up display, the support rigidity of the head-up display is increased, and the instrument panel and other components other than the annular support member can be used in common across vehicles with different specifications. Therefore, according to the above configuration, it is possible to improve the support rigidity of the head-up display and standardize components.

[0012] The annular support member described above has a plurality of outer connection parts that are connected to the instrument panel on both sides of the upper opening in the vehicle width direction, and a plurality of inner connection parts that are provided on the upper opening side of the plurality of outer connection parts and to which the head-up display is connected. The plurality of outer connection parts are provided spaced apart in the front-rear direction, and the plurality of inner connection parts are provided in the range between the plurality of outer connection parts in the front-rear direction.

[0013] According to the above configuration, by connecting the outer peripheral side of the annular support member to the instrument panel and supporting the head-up display on the inner peripheral side, the head-up display can be supported with higher rigidity and stably supported.

[0014] The plurality of outer connection portions are connected to the instrument panel by a connection shaft extending obliquely upward in the rear of the vehicle, and the plurality of inner connection portions are connected to the head-up display by a connection shaft extending in the vertical direction.

[0015] According to the above configuration, by changing the direction of the connection shaft between the outer connection portion and the inner connection portion, the directions in which each connection shaft is easily affected by vibration are made different, and it becomes possible to support the head-up display more stably.

[0016] The above instrument panel further has a first panel-side connection portion provided on both sides in the vehicle width direction of the upper surface opening on the lower side of the upper surface portion to which the outer connection portion is connected. The first panel-side connection portion includes a first end surface portion extending downward from the upper surface portion so as to face the front of the vehicle, a first side wall portion extending from the side edge of the first end surface portion to the rear of the vehicle, a first lower surface portion extending from the lower edge of the first end surface portion along the lower edge of the side wall portion to the rear of the vehicle, and a first connection point provided on the first end surface portion to which one of the plurality of outer connection portions is connected. The lower edge of the first side wall portion approaches the upper surface portion toward the rear of the vehicle, and the rear end of the first lower surface portion is connected to the upper surface portion.

[0017] According to the above panel-side connection portion, it becomes possible to attach the annular support member with higher rigidity and further improve the support rigidity of the head-up display.

[0018] The above instrument panel further has a second panel-side connection portion provided below the first panel-side connection portion. The second panel-side connection portion has a second end surface portion that extends downward from the lower surface portion so as to face the front of the vehicle, a second side wall portion that extends rearward of the vehicle from the side edge of the second end surface portion, a second lower surface portion that extends rearward of the vehicle along the lower edge of the second side wall portion from the lower edge of the second end surface portion, and a second connection point provided on the second end surface portion to which another one of the plurality of outer connection portions is connected. The lower edge of the second side wall portion approaches the lower surface portion as it goes rearward of the vehicle, and the rear end of the second lower surface portion is connected to the upper surface portion.

[0019] Also, by the above second panel-side connection portion, it becomes possible to attach the annular support member with higher rigidity and further improve the support rigidity of the head-up display.

[0020] Each of the above plurality of inner connection portions includes a protruding portion that protrudes upward in a rectangular shape and a connection point formed on the upper surface of the protruding portion. The upper surface of the protruding portion in the inner connection portion on the rear side of the vehicle among the plurality of inner connection portions is formed at a position higher than the upper surface of the protruding portion in the inner connection portion on the front side of the vehicle.

[0021] According to the above configuration, by making the heights of the protruding portions of the plurality of inner connection portions different from each other, it is possible to further improve the support rigidity of the head-up display, such as improving the second moment of area of the annular support member and making it easier to absorb vibration.

[0022] The protruding portion of the inner connection portion on the front side of the vehicle and the protruding portion of the inner connection portion on the rear side of the vehicle are separated in the front-rear direction of the vehicle.

[0023] Also, according to the above configuration, it is possible to further improve the support rigidity of the head-up display, such as improving the second moment of area of the annular support member and making it easier to absorb vibration.

[0024] The instrument panel structure for the vehicle further includes a steering support member provided in front of the instrument panel and a reinforcing member connecting the steering support member and the annular support member, wherein the reinforcing member is connected to the area of ​​the annular support member between the inner connection portion on the front side of the vehicle and the inner connection portion on the rear side of the vehicle.

[0025] According to the reinforcing member described above, it becomes possible to support the annular support member using the steering support member, thereby further increasing the support rigidity of the head-up display.

[0026] The opening on the top of the instrument panel shown above was created using a laser cutter.

[0027] According to the above configuration, the instrument panel can be manufactured using the same mold whether or not it includes a head-up display. Furthermore, in the case of the specification that includes a head-up display, the top opening can be formed using a laser cutter, eliminating the need to prepare a new mold and reducing costs and production time. Moreover, using a laser cutter allows for greater design flexibility of the instrument panel, as it is not affected by mold combinations, etc.

[0028] The top opening of the instrument panel described above is cut by applying a laser cutter along a line segment that slopes in the front-to-rear direction of the vehicle, and when viewed directly from the top opening, the edge of the top opening is curved with a curvature of 20 mm or more.

[0029] With the top opening of the above configuration, processing with a laser cutter becomes easier, improving the design flexibility of the instrument panel. [Examples]

[0030] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The dimensions, materials, and other specific numerical values ​​shown in these embodiments are merely illustrative to facilitate understanding of the invention and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustrations.

[0031] Figure 1 shows a vehicle instrument panel structure (hereinafter referred to as instrument panel structure 100) according to an embodiment of the present invention. Hereafter, in Figure 1 and all other drawings of this application, the front-rear direction of the vehicle is illustrated by arrows F (Forward) and B (Backward), the left and right directions in the vehicle width direction are illustrated by arrows L (Leftward) and R (Rightward), and the up-down direction of the vehicle is illustrated by arrows U (Upward) and D (Downward).

[0032] The instrument panel structure 100 comprises an instrument panel 102 and a head-up display 104. The instrument panel 102 is a resin panel member and is assembled and installed on the steering support member 116 (see Figure 3) at the front of the vehicle. Numerous components, such as the head-up display 104 and the meter 106, are installed on the instrument panel 102.

[0033] The head-up display 104 is a device that displays information above the instrument panel 102. It is positioned on the upper surface 102a of the instrument panel 102, and the display portion can be raised upwards. A garnish 108, which serves as a cover, is attached around the head-up display 104.

[0034] Figure 2 shows the instrument panel 102 with the garnish 108 removed. An upper opening 110 is formed in the upper surface portion 102a of the instrument panel 102. The upper opening 110 is an area covered by the garnish 108 and is open to dimensions that allow the head-up display 104 to be accommodated.

[0035] Figure 3 is a perspective view of the instrument panel structure shown in Figure 2, viewed from below the front of the vehicle. In this embodiment, an annular support member 112 is attached to the lower side of the upper opening 110 (see Figure 2) of the instrument panel 102. The annular support member 112 is a resin member for fixing the head-up display 104, and the head-up display 104 is fixed via a bracket 114.

[0036] The bracket 114 is a mainly metal component that holds and secures the head-up display 104, and is installed inside the annular support member 112 so as to span across the width of the vehicle, and supports the lower surface of the head-up display 104.

[0037] The steering support member 116 is a component that supports a steering device (not shown) and is composed of a long pipe section 118. The pipe section 118 extends in the vehicle width direction in front of the instrument panel 102 and below the upper opening 110 (see Figure 2), and is fixed to the vehicle body. The pipe section 118 is provided with multiple stays (not shown), which support the instrument panel 102.

[0038] The reinforcing members 120 and 122 are members that connect the pipe section 118 and the annular support member 112. The lower ends of the reinforcing members 120 and 122 are joined to the pipe section 118, and the upper ends are joined to the annular support member 112. With this configuration, the load of the head-up display 104 applied to the annular support member 112 can be distributed to the pipe section 118 via the reinforcing members 120 and 122.

[0039] Figure 4 is a perspective view of the annular support member 112 shown in Figure 3, viewed from the upper rear of the vehicle. As described above, the annular support member 112 is an annular shape made of resin, with a central opening 124 formed in the center, and is attached to the lower side of the upper surface portion 102a of the instrument panel 102 by overlapping the central opening 124 with the upper surface opening 110 (see Figure 2). To improve rigidity, the annular support member 112 has a rib structure 126 consisting of front and rear ribs 126a and left and right ribs 126b, which are provided at multiple locations around the central opening 124.

[0040] The side portions 112a and 112b of the annular support member 112 are located on both the left and right sides in the vehicle width direction of the upper opening 110 (see Figure 2). The side portions 112a and 112b extend away from the upper opening 110 from the upper end of the vertical wall portion 128 that forms the inner circumference of the upper opening 110, and have an overall upward convex structure. Multiple connection points for the instrument panel 102 and the head-up display 104 are provided on the side portions 112a and 112b.

[0041] The outer connection parts 130, 132, 134, and 136 are the parts that connect to the instrument panel 102, and multiple such parts are provided on the outer circumference side of the side parts 112a and 112b opposite to the upper opening 110. For example, on the left side part 112a in the vehicle width direction, the front outer connection part 130 and the rear outer connection part 132 are provided spaced apart in the vehicle's longitudinal direction.

[0042] The outer connection portion 130 has a connection surface 138 that faces slightly upward toward the rear of the vehicle, and through holes 140 and 142 provided on the connection surface. The through holes 140 and 142 are connected to the instrument panel 102 using fasteners such as bolts. The lower end of the fixing surface 144 of the front outer connection portion 130 and the upper end of the fixing surface 144 of the rear outer connection portion 132 are connected in the front-rear direction by an inclined surface 150 that slopes upward toward the rear of the vehicle.

[0043] Multiple internal connection points 152, 154, 156, and 158 are the parts to which the head-up display 104 is connected via the bracket 114, and are located on the side portions 112a and 112b that are closer to the upper opening 110 than the external connection points 130, 132, 134, and 136. For example, on the left side portion 112a in the vehicle width direction, the front internal connection point 152 and the rear internal connection point 154 are spaced apart in the vehicle's longitudinal direction. Legs 210 and 212 (see Figure 2) formed at the vehicle width ends of the bracket 114 are fixed to these internal connection points 152 and 154 using bolts 214, 216, etc.

[0044] Figure 5 shows the instrument panel 102 from Figure 3 with the annular support member 112 and other components removed. Below the upper surface portion 102a of the instrument panel 102, first panel-side connection portions 160 and 162 are provided, corresponding to the shapes of the outer connection portions 130 and 134 of the annular support member 112.

[0045] The first panel side connection portions 160 and 162 are generally convex downwards and are provided in pairs symmetrically on both sides in the vehicle width direction of the upper opening 110 below the upper surface portion 102a.

[0046] Let's take the first panel-side connection portion 160 on the left side in the vehicle width direction as an example. The first end face portion 164 of the first panel-side connection portion 160 is located at the front end of the vehicle and extends downward from the upper surface portion 102a so as to face the front of the vehicle. The first side wall portion 166 bends towards the rear of the vehicle from the side edge of the first end face portion 164 and extends along the upper surface portion 102a. The lower edge 168 of the first side wall portion 166 approaches the upper surface portion 102a as it moves towards the rear of the vehicle.

[0047] The first lower portion 170 bends towards the rear of the vehicle from the lower edge of the first end portion 164 and extends along the lower edge 168 of the first side wall portion 166. The rear end 172 of the first lower portion 170 is connected to the upper portion 102a.

[0048] The first connection points 174 and 175 are the parts to which the through holes 140 and 142 of the outer connection part 130 are connected, and are provided on the first end face part 164. The first connection point 174, which is on the outside when viewed from the top opening 110, is realized as a boss hole that is fastened to the through hole 140 of the outer connection part 130 by a bolt 194 (see Figure 6), etc. The first connection point 175, which is closer to the top opening 110, is realized as a pin that is inserted into the through hole 142 of the outer connection part 130.

[0049] Below the front of the first panel-side connection portions 160 and 162, second panel-side connection portions 176 and 178 are also provided. The second panel-side connection portions 176 and 178 are also the parts to which the outer connection portions 132 and 136 of the annular support member 112 (see Figure 4) are connected, and a pair of them are provided symmetrically on both sides in the vehicle width direction of the upper opening 110 below the upper surface portion 102a.

[0050] The second end face portion 180 of the second panel-side connection portion 176 is located at the front end of the vehicle of the second panel-side connection portion 176 and extends downward from the upper surface portion 102a so as to face the front of the vehicle. The second side wall portion 182 bends towards the rear of the vehicle from the side edge of the second end face portion 180 and extends along the upper surface portion 102a. The lower edge 184 of the second side wall portion approaches the upper surface portion 102a as it moves towards the rear of the vehicle.

[0051] The second lower portion 186 bends towards the rear of the vehicle from the lower edge of the second end portion 180 and extends along the lower edge 184 of the second side wall portion 182. The rear end 188 of the second lower portion 186 is connected to the upper portion 102a.

[0052] The second connection points 190 and 192 are the parts to which the through holes 146 and 148 of the outer connection part 132 (see Figure 4) are connected, and are provided on the second end face part 180. The second connection point 190, which is on the outside when viewed from the top opening 110, is realized as a boss hole that is fastened to the through hole 146 of the second outer connection part 132 by a bolt 196 (see Figure 6). The second connection point 192, which is closer to the top opening 110, is realized as a pin that is inserted into the through hole 148 of the second outer connection part 132.

[0053] The first panel-side connection parts 160, 162 and the second panel-side connection parts 176, 178 described above allow the annular support member 112 (see Figure 4) to be attached with greater rigidity, thereby further improving the support rigidity of the head-up display 104 (see Figure 3).

[0054] Figure 6 is a cross-sectional view AA of the instrument panel structure 100 in Figure 3. Cross-section AA is a cross-section that passes through the outer connection portions 130 and 132 of the annular support member 112 in Figure 4, and the first panel-side connection portion 160 and the second panel-side connection portion 176 of the instrument panel 102 in Figure 5, both vertically and horizontally.

[0055] The outer connection portions 130 and 132 of the annular support member 112 are connected to the first panel-side connection portion 160 and the second panel-side connection portion 176 of the instrument panel 102 by fastening bolts 194 and 196. At this time, the outer connection portions 130 and 132 are connected along connection axes S1 and S2 that extend diagonally upward from the front of the vehicle to the rear of the vehicle.

[0056] Figure 7 is a cross-sectional view of the BB of the instrument panel structure 100 in Figure 2. The BB cross-section is a cross-sectional plane that passes through the inner connection portions 152 and 154 of the annular support member 112 in Figure 4, both vertically and horizontally.

[0057] Here, the inner connection parts 152 and 154 in Figure 4 are formed in a shape that protrudes upward. For example, in the inner connection part 152 on the front side of the vehicle, the projection 198 is a rectangular part that protrudes upward, and the connection point 202 is formed as a bolt hole on the upper surface 200 of the projection 198. In the case of the inner connection part 154 on the rear side of the vehicle, there is a rectangular projection 204 that protrudes upward, and a connection point 208 formed as a bolt hole on the upper surface 206 of the projection.

[0058] As shown in Figure 7, the inner connection parts 152 and 154 are fastened to the upper side of the bracket 114's legs 210 and 212 using bolts 214 and 216 and washers 218 and 220. In this way, the head-up display 104 (see Figure 3) is indirectly connected to the inner connection parts 152 and 154.

[0059] The inner connection parts 152 and 154 are connected to the bracket 114 that supports the head-up display 104 by connection shafts S3 and S4 that extend in the vertical direction. On the other hand, as explained with reference to Figure 6, the outer connection parts 130 and 132 are connected along connection shafts S1 and S2 that extend diagonally upward from the front of the vehicle to the rear of the vehicle.

[0060] According to the above configuration, by changing the direction of the connection axes S1, S2 and S3, S4 between the outer connection parts 130, 132 and the inner connection parts 152, 154, the direction in which each connection axis is susceptible to vibration is made different, making it possible to support the head-up display 104 more stably.

[0061] The connection points 202 and 208 of the inner connection parts 152 and 154 are separated by a distance D1 in the front-to-back direction. On the other hand, the through holes 140 and 146 of the outer connection parts 130 and 132 in Figure 6 are separated by a distance D2 in the front-to-back direction. In this case, the connection points 202 and 208 of the inner connection parts 152 and 154 are provided to fall within the range between the distance D2 in the front-to-back direction of the through holes 140 and 146 of the outer connection parts 130 and 132. Therefore, the distance D1 of the connection points 202 and 208 of the inner connection parts 152 and 154 is set to be shorter than the distance D2 of the through holes 140 and 146 of the outer connection parts 130 and 132 (D2 > D1).

[0062] According to the above configuration, by connecting the outer circumference of the annular support member 112 to the instrument panel 102 and supporting the head-up display 104 (see Figure 3) with its inner circumference, the head-up display 104 can be supported with greater rigidity and stably.

[0063] Furthermore, the upper surface 206 of the protruding portion 204 on the rear inner connection portion 154 of the vehicle is formed at a height H1 higher than the upper surface 200 of the protruding portion 198 on the front inner connection portion 152 of the vehicle.

[0064] According to the above configuration, by making the heights of the protruding portions 198 and 204 of the multiple inner connection portions 152 and 154 different, the second moment of area of ​​the annular support member 112 is improved, making it easier to absorb vibrations, and thus the support rigidity of the head-up display 104 (see Figure 3) can be further improved.

[0065] The protruding portion 198 of the inner connection portion 152 on the front side of the vehicle and the protruding portion 204 of the inner connection portion 154 on the rear side of the vehicle are spaced apart in the longitudinal direction of the vehicle, and a concave portion 222 is formed in the area between them. This configuration also improves the second moment of area of ​​the annular support member 112, making it easier to absorb vibrations and further improving the support rigidity of the head-up display 104.

[0066] The upper end flange 224 of the reinforcing member 120 is connected by bolts 228 to a concave boss portion 226 of the annular support member 112, along a connecting shaft S5 that extends from below diagonally upward and rearward.

[0067] With the reinforcing members 120 and 122 (see Figure 3) configured as described above, the annular support member 112 can be supported using the steering support member 116, making it possible to further increase the support rigidity of the head-up display 104.

[0068] As described above, according to the instrument panel structure 100 of this embodiment, a separate annular support member 112 (see Figure 4) is used from the instrument panel 102 to form a two-layer structure of the instrument panel 102 and the annular support member 112, and the head-up display 104 (see Figure 3) is installed. With this configuration, for example, the annular support member 112 can be formed using a material with higher rigidity than the material used for the instrument panel 102, making it possible to further increase the support rigidity of the head-up display 104.

[0069] Furthermore, according to this embodiment, the instrument panel 102 and other components other than the annular support member 112 can be used in common across vehicles with different specifications. Therefore, according to this embodiment, it is possible to improve the support rigidity of the head-up display 104 and to standardize the components.

[0070] Figure 8 is an example of the top opening 110 in Figure 2. Figure 8(a) is an example of the top opening 110 in Figure 2 shown alone. In this embodiment, the instrument panel 102 has a top opening 110 cut out by a laser cutter on the top surface portion 102a of another instrument panel where the head-up display 104 is not located.

[0071] In this embodiment, when the top opening 110 is viewed directly, the edge 230 of the top opening 110 is curved with a curvature of 20 mm or more, indicated by a virtual circle R1. With this configuration, the top opening 110 can be easily processed with a laser cutter, improving the design flexibility of the instrument panel 102.

[0072] Figure 8(b) is a cross-sectional view of the CC near the upper opening 110 of the instrument panel 102 shown in Figure 8(a). The upper opening 110 is cut by applying a laser along a line segment L2 that is inclined at an angle α1 toward the front of the vehicle with respect to a line segment L1 that extends vertically in line with the inclination of the upper surface portion 110a. This configuration allows the laser to be applied perpendicularly to the upper surface portion 110a, enabling the upper opening 110 to be formed efficiently.

[0073] According to the above configuration, the instrument panel 102 can be manufactured using the same mold whether or not it is designed to include a head-up display 104. Furthermore, in the case of the specification that includes a head-up display 104, the top opening 110 can be formed using a laser cutter, eliminating the need to prepare a new mold and reducing costs and production man-hours. Moreover, by using a laser cutter, the design flexibility of the instrument panel 102 can be increased, as it is not affected by mold combinations, etc.
