JP 2016-37216 A

  When a head-up display fails, the failed head-up display is often replaced with a new head-up display. According to the technique of Patent Literature 1, since the bracket used for fixing the head-up display is erected between the head-up display and the living space of the vehicle, the replacement work of the head-up display is hindered by the bracket. The

  An object of the present invention is to provide a technique that enables easy replacement of a head-up display.

  A head-up display mounting structure according to an aspect of the present invention includes a head-up display unit having a housing in which an optical device that generates projection light for displaying an image on a reflecting surface attached to a vehicle body is housed. A first bracket fixed to the cross car beam and the dash panel, an attachment member disposed between the first bracket and the housing, and having a first fixing portion fixed to the first bracket; Is provided. The attachment member includes a second fixing portion fixed to the cross car beam. The head-up display unit is disposed in a space formed between an instrument panel and the mounting member, and is fixed to the mounting member.

  According to said structure, an attachment member is fixed to a 1st bracket in the 1st fixing | fixed part between the 1st bracket fixed to the cross car beam and the dash panel, and the housing | casing of a head-up display unit, In addition, since the second fixing portion is fixed to the cross car beam, the mounting member is stably supported by the vehicle body. Since the head-up display unit is attached to the attachment member, the shake of the vehicle body becomes a shake that substantially matches the reflection surface attached to the vehicle body and the head-up display, and the image position on the windshield hardly fluctuates. Therefore, the driver can observe the image comfortably.

  Since the head-up display unit is disposed in the space formed between the instrument panel and the mounting member and is fixed to the mounting member, the operator removes the decorative plate that forms the outer surface of the instrument panel, The up display unit can be easily accessed. Therefore, the mounting structure described above allows easy replacement of the head-up display.

  With regard to the above configuration, the attachment member may include a panel fixing portion that is fixed to the panel member that forms the upper surface of the instrument panel in front of the second fixing portion. The first fixing part may be located behind the panel fixing part and ahead of the second fixing part.

  According to said structure, since a 1st fixing | fixed part is located behind the panel fixing | fixed part and ahead of the 2nd fixing | fixed part, the fixing position of an attachment member does not line up in a horizontal direction. Therefore, the mounting member is less likely to swing around the axis extending in the lateral direction, and is stably supported by the vehicle body. Since the head-up display unit is attached to the attachment member, the shake of the vehicle body becomes a shake that substantially matches the reflection surface attached to the vehicle body and the head-up display, and the image position on the windshield hardly fluctuates. Therefore, the driver can observe the image comfortably.

  With respect to the above configuration, the attachment member may include a first plate portion having the second fixing portion and a second plate portion including the panel fixing portion. The head-up display unit includes a first unit fixing portion fixed to the first plate portion behind a corner portion formed between the first plate portion and the second plate portion, and the corner portion. And a second unit fixing portion fixed to the second plate portion above the second plate portion.

  According to the above configuration, the first unit fixing portion is fixed to the first plate portion behind the corner portion formed between the first plate portion and the second plate portion. The first unit fixing part can be easily accessed. Since the second fixing portion is fixed to the second plate portion above the corner portion, the operator can easily access the second unit fixing portion. Therefore, the operator can easily remove the head-up display unit from the mounting member. In addition, the operator can easily attach another head-up display unit to the attachment member. That is, the operator can easily replace the head-up display unit.

  With respect to the above configuration, the first fixing portion may be positioned forward of the cross car beam. The head-up display unit may include a rear end surface located behind the cross car beam.

  According to said structure, since a 1st fixing | fixed part is located ahead of a cross car beam, the 1st fixing | fixed part and 2nd fixing | fixed part of an attachment member are located in a line with front and back. Therefore, the attachment member is stably supported by the vehicle body. As a result, the shake of the vehicle body is substantially the same as the reflection surface attached to the vehicle body and the head-up display, and the image position on the windshield hardly fluctuates. Therefore, the driver can observe the image comfortably. Since the rear end surface of the head-up display unit is located behind the cross car beam, the operator can easily access the head-up display unit. Therefore, the operator can easily replace the head-up display unit.

  With regard to the above configuration, the mounting structure may further include a second bracket that extends forward from the cross car beam on a side of the first bracket. The attachment member may include a third fixing portion that is fixed to the second bracket. The third fixing part may be located in front of the first fixing part.

  According to said structure, since an attachment member is attached to the 2nd bracket extended ahead from a cross car beam in the side of a 1st bracket in a 3rd fixing | fixed part, a 3rd fixing | fixed part is a 1st fixing | fixed part and It will be located to the side of the 2nd fixed part. In addition, since the third fixing portion is positioned in front of the first fixing portion, the first fixing portion, the second fixing portion, and the third fixing portion are arranged in the front-rear direction. . Therefore, the attachment member is stably supported by the vehicle body. As a result, the shake of the vehicle body is substantially the same as the reflection surface attached to the vehicle body and the head-up display, and the image position on the windshield hardly fluctuates. Therefore, the driver can observe the image comfortably.

  With regard to the above configuration, the mounting structure may further include a third bracket extending forward from the cross car beam on a side of the first bracket. The first bracket may be located between the second bracket and the third bracket. The attachment member may include a fourth fixing portion that is fixed to the third bracket. The fourth fixing portion may be located in front of the first fixing portion and rearward of the third fixing portion.

  According to the above configuration, since the first bracket is located between the second bracket and the third bracket, the third fixing portion and the fourth fixing portion are respectively lateral to the first fixing portion and the second fixing portion. Will be located. Therefore, the attachment member is stably supported by the vehicle body. As a result, the shake of the vehicle body is substantially the same as the reflection surface attached to the vehicle body and the head-up display, and the image position on the windshield hardly fluctuates. Therefore, the driver can observe the image comfortably.

  With regard to the above configuration, the first bracket includes a first portion extending forward from the cross car beam, a second portion bent downward from the first portion, and a third portion bent forward from the second portion. And may be included. The first fixing portion may be fixed to the first portion. The third portion may be fixed to the dash panel.

  According to said structure, the rearward impact force which acts on a dash panel at the time of a vehicle collision is transmitted to the 3rd part fixed to the dash panel. Since the third portion continues to the second portion bent downward from the first portion, the second portion and the third portion can be deformed according to the impact force and absorb the impact force. Since the attachment member is fixed to the first portion in the first fixing portion, the connection of the attachment member to the first bracket hardly affects the shock absorbing performance of the first bracket.

  With regard to the above configuration, the first portion may have a wider lateral width than the third portion.

  According to said structure, since a 1st part has a lateral width wider than a 3rd part, an attachment member is stably supported on a 1st bracket.

  With respect to the above configuration, the first portion may narrow toward the second portion.

  According to said structure, since a 1st part narrows toward a 2nd part, the designer can give a thin shape to a 2nd part and a 3rd part. Since the second portion and the third portion are easily deformed, the first bracket can effectively absorb the impact force.

  The technique described above allows easy replacement of the head-up display.

It is a schematic bottom view of the attachment structure shown by FIG. It is a schematic perspective view of the attachment member of the attachment structure shown by FIG. It is a schematic perspective view of the attachment structure shown by FIG. It is a schematic perspective view of the attachment structure shown by FIG.

  FIG. 1 is a schematic perspective view of an exploded exemplary mounting structure 100. The attachment structure 100 will be described with reference to FIG. For the purpose of clarifying the terminology and direction, such as “left”, “right”, “front”, “rear”, “up” and “down”. Accordingly, these terms should not be used to limit the interpretation of the principles of this embodiment.

  The mounting structure 100 includes a head-up display unit (hereinafter referred to as “HUD unit 110”), a first bracket 120, and a mounting member 130. The HUD unit 110 has a housing 111. The casing 111 forms the outer surface of the HUD unit 110. The HUD unit 110 further includes various optical devices (not shown: for example, a lens, a mirror, and a light source) disposed in the housing 111. These optical devices generate projection light according to the image signal. The projection light is directed to a reflecting surface (for example, a windshield (not shown), a hologram element (not shown) or a reflecting mirror (not shown)) attached to a vehicle body (not shown). It is projected through the transparent region 112 formed in the above. The projection light is reflected by the reflecting surface and enters the driver's eyes. As a result, the driver can receive various information from the image represented by the projection light. The HUD unit 110 may be various commercially available head-up display devices. Therefore, the principle of the present embodiment is not limited to a specific device used as the HUD unit 110.

  The attachment member 130 includes a left side wall 131, a right side wall 132, and a main plate 133. The main plate 133 is located between the left side wall 131 and the right side wall 132. The left side wall 131, the right side wall 132, and the main plate 133 are integrally formed by a resin molding technique. The HUD unit 110 is fixed on the main plate 133.

  The first bracket 120 extends forward from the cross car beam CCB. The main plate 133 of the mounting member 130 is fixed to the first bracket 120 and the cross car beam CCB.

  FIG. 2 is a schematic perspective view of the mounting structure 100. FIG. 3 is a schematic longitudinal sectional view of the mounting structure 100. The attachment structure 100 will be further described with reference to FIGS. 1 to 3.

  The first bracket 120 includes a first part 121, a second part 122, and a third part 123. The first portion 121 extends forward from the cross car beam CCB. The base end portion of the first portion 121 is fixed to the cross car beam CCB (see FIG. 2). The second portion 122 curves downward from the tip of the first portion 121. The third portion 123 includes a horizontal plate portion 124 and a tip plate portion 125. The horizontal plate portion 124 curves forward from the lower end of the second portion 122 and extends substantially horizontally. The tip plate portion 125 curves downward from the tip portion of the horizontal plate portion 124. The tip plate portion 125 is fixed to the dash panel DSP (see FIG. 3).

  FIG. 4A is a schematic plan view of the mounting structure 100. FIG. 4B is a schematic bottom view of the mounting structure 100. The attachment structure 100 will be further described with reference to FIGS. 3 to 4B.

  The main plate 133 of the attachment member 130 includes a first plate portion 134 and a second plate portion 135. The 1st board part 134 is arrange | positioned between the bottom face of the housing | casing 111 of the HUD unit 110, and the 1st part 121 of the 1st bracket 120 (refer FIG. 3). The second plate portion 135 is curved upward from the front end of the first plate portion 134. As a result, a curved corner portion 136 is formed between the first plate portion 134 and the second plate portion 135.

  3 to 4B show the screw SCW. Screw SCW passes through first portion 121 of first bracket 120 and first plate portion 134 of main plate 133 in front of cross car beam CCB. Therefore, the attachment member 130 is fixed to the first portion 121 of the first bracket 120 around the screw SCW. Regarding the present embodiment, the first fixing portion is exemplified by the region of the first plate portion 134 around the screw SCW.

  When a vehicle (not shown) collides, a rearward impact force is applied to the dash panel DSP (see FIG. 3). The impact force is sequentially transmitted to the front end plate portion 125, the horizontal plate portion 124, and the second portion 122 of the first bracket 120. As a result, the second portion 122 and the third portion 123 of the first bracket 120 can be deformed according to the impact force. Therefore, the second portion 122 and the third portion 123 can effectively absorb the impact force. As described above, the attachment member 130 is fixed to the first portion 121 of the first bracket 120 by the screw SCW. Therefore, the connection portion of the attachment member 130 and the first bracket 120 is a deformation portion of the first bracket 120 (that is, The second part 122 and the third part 123) are different in position. Therefore, the connection structure of the attachment member 130 and the first bracket 120 hardly inhibits the deformation of the second portion 122 and the third portion 123. That is, the connection structure of the attachment member 130 and the first bracket 120 is unlikely to adversely affect the shock absorption capability of the first bracket 120.

  FIG. 5 is a schematic perspective view of the attachment member 130 attached to the cross car beam CCB. The attachment member 130 will be described with reference to FIGS. 1, 3, and 5.

  The first plate portion 134 of the attachment member 130 includes a lateral beam portion 137 extending in the lateral direction. The lateral beam portion 137 forms a part of the rear end edge of the first plate portion 134. The horizontal beam portion 137 is disposed along the cross car beam CCB (see FIG. 5). Two through holes 138 are formed in the cross beam portion 137 (see FIG. 1).

  FIG. 1 shows two fixed pieces FPC. The through hole TRH is formed in each of these fixed pieces FPC. The attachment member 130 is installed on the cross car beam CCB so that the two through holes 138 overlap the through holes TRH of the two fixed pieces FPC, respectively. FIG. 5 shows two screws SCX. Each of the two screws SCX passes through the through holes 138 and TRH. As a result, the attachment member 130 is fixed not only to the first bracket 120 but also to the cross car beam CCB. With respect to the present embodiment, the second fixing portion is exemplified by the cross beam portion 137. The second fixing portion may have another structure that matches the shape and structure of the cross car beam CCB. Therefore, the principle of the present embodiment is not limited to the specific structure of the second fixing portion.

  FIG. 3 shows a panel member PNM that forms the upper surface of the instrument panel ISP. The HUD unit 110 is disposed in a space formed between the instrument panel ISP and the attachment member 130. The housing 111 of the HUD unit 110 includes a rear end surface 113. Since the rear end surface 113 is located behind the cross car beam CCB (see FIG. 3), when the decorative plate forming the outer surface of the instrument panel ISP is removed, the operator can easily access the rear end surface 113. can do. Since the attachment member 130 is located in front of the cross car beam CCB as a whole, the operation of the operator holding the rear end surface 113 and pulling out the HUD unit 110 rearward is not obstructed by the attachment member 130.

  The cross car beam CCB and the first bracket 120 form a part of the vehicle body. Since the HUD unit 110 is fixed to the cross car beam CCB and the first bracket 120 via the attachment member 130, the shaking of the vehicle body is directly transmitted to the HUD unit 110. At this time, the shaking of the HUD unit 110 substantially matches the shaking of the vehicle body. As with the HUD unit 110, a windshield (not shown) is also attached to the vehicle body. Therefore, the swing of the windshield substantially matches the swing of the vehicle body. Since the swing of the HUD unit 110 substantially coincides with the swing of the windshield, if the HUD unit 110 projects projection light onto the windshield, the position of the image on the windshield hardly fluctuates. Therefore, the driver can comfortably observe the image represented by the projection light.

The left column portion 235 and the right column portion 236 of the second plate portion 135 are located above the corner portion 136.

  As shown in FIG. 7, the HUD unit 110 includes a front plate 114 sandwiched between a casing 111 and a second plate portion 135. The casing 111 includes an upper casing 115 and a lower casing 116. The upper housing 115 is stacked on the lower housing 116, and cooperates with the lower housing 116 to form an internal space in which various optical devices are accommodated. The front plate 114 is fixed to the front surface of the upper housing 115. The front plate 114 includes a left ear portion 117 and a right ear portion 118. The left ear portion 117 and the right ear portion 118 protrude upward from the upper surface of the upper housing 115 and overlap the rear end surfaces of the left column portion 235 and the right column portion 236, respectively. As shown in FIG. 5, the through hole 237 is formed in the rear end surface of the left column portion 235. As shown in FIG. 5, the through hole 238 is formed in the rear end surface of the right column portion 236. FIG. 7 shows the screws SC1, SC2. The screw SC1 passes through a through hole (not shown) formed in the left ear portion 117 and a through hole 237 of the left column portion 235. The screw SC2 passes through a through hole (not shown) formed in the right ear part 118 and a through hole 238 of the right column part 236. As a result, the casing 111 is fixed to the second plate portion 135 of the attachment member 130 via the front plate 114. Regarding the present embodiment, the second unit fixing portion is exemplified by the left ear portion 117 and the right ear portion 118. The second unit fixing portion may have another structure that matches the shape of the second plate portion 135 of the attachment member 130. Therefore, the principle of this embodiment is not limited to the specific structure of the second unit fixing portion.

  The lower housing 116 includes a main part 211 and a protruding plate 212. The main part 211 is located below the upper housing 115 and cooperates with the upper housing 115 to form an internal space in which various optical devices are accommodated. The corner portion located at the lower left of the main portion 211 overlaps the rear end surface of the left column portion 232. The protruding plate 212 protrudes downward from the right end of the lower edge of the main portion 211 and overlaps the rear end surface of the right column portion 234. As shown in FIG. 5, the through hole 241 is formed in the rear end surface of the left column portion 232. The through hole 242 is formed in the rear end surface of the right column portion 234.

As a result, the casing 111 is fixed to the first plate portion 134 of the attachment member 130. Regarding the present embodiment, the first unit fixing portion is exemplified by the lower left corner of the main portion 211 and the protruding plate 212. The first unit fixing portion may have another structure that matches the shape of the first plate portion 134 of the attachment member 130. Therefore, the principle of this embodiment is not limited to the specific structure of the first unit fixing part.

(Additional bracket)
The attachment member may be supported using an additional bracket in addition to the first bracket. In the following, additional brackets are described.

  As shown in FIG. 4B, the mounting structure 100 further includes a second bracket 140 and a third bracket 150. The second bracket 140 extends forward from the cross car beam CCB on the right side of the first bracket 120. The third bracket 150 extends forward from the cross car beam CCB on the left side of the first bracket 120. Therefore, the first bracket 120 is located between the second bracket 140 and the third bracket 150.

  The second bracket 140 and the third bracket 150 are generally J-shaped. That is, the second bracket 140 and the third bracket 150 extend along the lower surface of the first plate portion 134 and bend along the corner portion 136. The tips of the second bracket 140 and the third bracket 150 are in contact with the front surface of the second plate portion 135.

  4B and 5 show the screws SC5 and SC6. The screw SC5 passes through a through hole (not shown) formed in the second bracket 140 and a through hole formed in the first plate portion 134. As a result, the second bracket 140 is connected to the cross car beam CCB and the attachment member 130. The screw SC6 passes through a through hole (not shown) formed in the third bracket 150 and a through hole formed in the first plate portion 134. As a result, the third bracket 150 is connected to the cross car beam CCB and the attachment member 130. Therefore, the attachment member 130 is supported not only by the first bracket 120 but also by the second bracket 140 and the third bracket 150. In the present embodiment, the third fixing portion is exemplified by the region of the second plate portion 135 around the screw SC5. The fourth fixing portion is exemplified by the region of the second plate portion 135 around the screw SC6.

  The screw SC5 on the right side of the screw SCW is located in front of the screw SCW. The screw SC6 on the left side of the screw SCW is located in front of the screw SCW and behind the screw SC5. Since the screws SCW, SC5, and SC6 are not aligned in a line in the lateral direction and the front-rear direction, the mounting member 130 can receive the first bracket 120, the second bracket 140, and the third bracket even when receiving various forces in the directions. 150 is stably supported.

(Shape of the first bracket)
The designer can give various shapes to the first bracket. Hereinafter, an exemplary shape of the first bracket will be described.

  As shown in FIG. 4B, the first portion 121 of the first bracket 120 has a wider side width than the second portion 122 and the third portion 123. As described above, the attachment member 130 is fixed to the widest first portion 121 in the first bracket 120, so that the attachment member 130 is stably supported by the first bracket 120.

  As shown in FIG. 4B, the first portion 121 of the first bracket 120 narrows toward the second portion 122. As a result, the second portion 122 is smoothly continuous with the first portion 121. Since there is no cross-sectional difference at the boundary between the first part 121 and the second part 122, an excessively large load is applied during the deformation of the second part 122 and the third part 123 during a vehicle (not shown) collision. Is unlikely to occur at the boundary between the first portion 121 and the second portion 122. Therefore, the second portion 122 and the third portion 123 can be deformed without being broken from the first portion 121. As a result, the first bracket 120 can effectively absorb an impact caused by a vehicle collision.

  The various features described above may be combined to suit the overall design of various vehicles.

  The principle of the above-described embodiment is preferably used for various mounting structures for mounting a head-up display.
