Description

  The present invention relates to a mounting structure for a head-up display device installed on an instrument panel of a vehicle (hereinafter abbreviated as an instrument panel. However, a place where an accurate notation is required is an instrument panel as it is). The present invention relates to a mounting structure for a head-up display device that can improve assemblability at the time of manufacture and serviceability after manufacture.

  Conventionally, a meter device is installed in the instrument panel of a vehicle, and a driver or the like confirms vehicle information such as a vehicle speed from the meter device. However, if the driver tries to check the meter device while the vehicle is traveling, the line of sight is inevitably diverted from the front of the vehicle to the lower side, which is not desirable from the viewpoint of traveling safety of the vehicle.

  Therefore, in recent years, an information display device called a “head-up display device” is being adopted in order to increase the driving safety of the vehicle, and many head-up display devices are installed on the upper instrument panel of the vehicle. .

  There are various types of this head-up display device, but it can be broadly divided into a glass irradiation type that displays light by directly irradiating light on the windshield in front of the driver's seat, and a small translucent called a combiner. There is a combiner type in which a screen plate (half mirror) is erected and information is displayed by irradiating light to the combiner.

  Since any head-up display device requires a relatively large unit, it becomes a problem how to install this large unit on the upper panel of the vehicle.

  In the following Patent Document 1, the unit of the head-up display device and the unit of the meter device are sub-assembled (temporarily assembled and fixed) into one unit, and this one unit is a large opening at the front position of the driver's seat on the instrument panel. Have been proposed (see paragraphs [0053] to [0054] of Patent Document 1).

  By adopting this mounting structure, the head-up display device and the meter device can be integrated into the instrument panel as a single unit, so that the assembling work can be simplified. Moreover, there is also an effect that it is possible to easily make a glass irradiation type and a combiner type by simply making a meter hood on the upper surface.

  By the way, in the case where such a head-up display device is installed in the upper part of the instrument panel, it is required to improve the assembly workability during manufacture and the service workability after manufacture in order to reduce the burden on the operator.

  Here, looking at the mounting structure of Patent Document 1 described above, it is difficult to say that the service workability after manufacture is considered, although the assembly workability during manufacture is considered. This is because, in service work after manufacture, a windshield is installed above the instrument panel, and it is necessary to remove the head-up display device so as not to interfere with the windshield. This is because the up-display device and the meter device are integrated into one unit, and the one-unit device may interfere with the windshield above the instrument panel.

  In addition, in the mounting structure disclosed in Patent Document 1, since it is necessary to form a large opening at a position in front of the driver's seat in the instrument panel, there is also a problem that the degree of freedom in designing the instrument panel surface is limited.

  The present invention has been made in view of such a point, and the object thereof is to manufacture a head-up display device mounting structure in which a head-up display device is mounted on an upper instrument panel while ensuring a degree of freedom in designing the instrument panel. An object of the present invention is to provide a mounting structure for a head-up display device that can improve both the assembly workability at the time and the service workability after manufacture.

Since it is free, only the unit body can be removed from the support bracket and only the unit body can be removed from the inside of the instrument panel.

  Therefore, while the assembly workability at the time of manufacture of the head-up display device can be easily performed, it can be removed in a small state of the unit body at the time of service, so the burden on the operator can be reduced and service workability can be reduced. Can be increased.

  In a third aspect of the present invention, a guide portion for guiding the head-up display device to an installation position above the instrument panel when assembling from above is provided in the lower portion of the support bracket.

  According to this configuration, when the head-up display device is assembled from above the instrument panel, since the guide portion is provided at the lower portion of the support bracket that is the tip in the assembly direction, the head-up display device is dropped from the approximate position. As a result, it is automatically guided to the installation position at the upper part of the instrument panel, so that the assembly work at the time of manufacture can be performed more easily.

  Therefore, the assembly workability at the time of manufacturing the head-up display device can be further enhanced.

  In a fourth aspect of the invention, the support bracket is provided with a lower fixing portion fixed to the instrument panel member at the lower portion and an upper fixing portion fixed to the upper end portion of the instrument panel core at the upper portion. is there.

  According to this configuration, the support bracket has the lower fixing portion fixed to the instrument panel member and the upper fixing portion fixed to the upper end portion of the instrument panel core. For this reason, since the support bracket is fixed to the instrument panel reinforcing member having a long vertical span and a strong vertical position, the support rigidity of the unit body can be increased.

  Therefore, the head-up display device can be stably fixed and installed on the upper portion of the instrument panel.

  In a fifth aspect of the invention, the unit main body is provided with grip portions that are gripped by an operator at both side positions in the vehicle width direction during assembly during manufacture and during removal during service.

  According to this configuration, since both sides of the unit body in the vehicle width direction are provided with gripping portions that the operator grips, at the time of manufacture, the operator holds the head-up display device firmly with both hands, Can be assembled to the top of the instrument panel. Also, at the time of service, the operator can remove the unit main body while holding the holding part firmly with both hands.

  In other words, at the time of manufacturing and at the time of service, the operator can hold the same gripping part with both hands to assemble the head-up display device or remove the unit body, so there is no need to set a separate gripping part for each. However, it is possible to perform assembling work and detaching work by firmly grasping with one gripping part.

  Therefore, even if the worker works from different openings at the time of manufacture and at the time of service, the worker can hold the unit main body and the like firmly and stably by gripping the same gripping portion.

  As described above, according to the present invention, the head-up display device can be easily assembled to the instrument panel from above without making the opening of the instrument panel so large. During service, the unit body can be removed from the meter opening on the back of the instrument panel. For this reason, even if the windshield is installed above the instrument panel at the time of service, only the unit main body of the head-up display device can be removed without interfering with the windshield.

  Therefore, in the mounting structure of the head-up display device that attaches the head-up display device to the upper part of the instrument panel of the vehicle, the assembly workability at the time of manufacture and the service workability after the manufacture are ensured while ensuring the design freedom of the instrument panel. Both can be enhanced.

On the other hand, FIG. 8 is a cross-sectional view showing the initial removal state during service, FIG. 9 is a cross-sectional view showing the first half of the removal state during service, and FIG. 10 is a cross-sectional view showing the second half of the removal state during service. 11 is a cross-sectional view showing the latter half of the detached state at the time of service. In addition, about the detail of the component of each figure, description is abbreviate | omitted by attaching | subjecting the code | symbol shown in FIG.

  First, the assembly method at the time of manufacture will be described with reference to FIGS.

  As shown in FIG. 6, at the time of manufacture, the front window glass 1 (see FIG. 5) is not mounted on the vehicle body, so that a wide space Z exists above the instrument panel 2. Therefore, the head-up display device 6 is assembled by dropping it from above the instrument panel 2 in a sub-assy state in which the unit main body 7 and the support bracket 8 are integrated.

  Specifically, an operator or the like grasps the head-up display device 6 in a state in which the unit main body 7 and the support bracket 8 are sub-assembled, grasps the grip portion 72 of the unit main body 7 with both hands, and Assembling is performed by dropping into the inside of the instrument panel 2 through the assembling opening 24.

  At this time, the dimension I1 of the assembly opening 24 of the instrument panel upper 21 is set to be larger than the dimension H1 of the sub-assembled head-up display device 6 (FIG. 6 shows only the front-rear direction and the width direction). 4), the operator can drop the head-up display device 6 into the instrument panel 2 relatively easily.

  The dimension I1 of the assembly opening 24 is set as small as possible so that the rear end portion 21Z of the instrument panel upper 21 is integrated with the instrument panel upper 21 as it is. This is the portion where the rear end portion 21Z of the instrument panel upper 21 is closest to the driver's eyes and is conspicuous, so that in the design of the instrument panel 2, it is a part that wants to ensure the design freedom with the other instrument panel upper 21. Because.

  Further, as described above, the lower fixing portion 83 and the protruding guide portion 94 are provided at the lower portion of the support bracket 8 so as to function as a guide portion when assembling from above, so that the worker can be at a rough position. By simply dropping the head-up display device 6 from above, the head-up display device 6 can be guided and installed at a predetermined position.

  FIG. 7 shows the latter half of the assembled state of the head-up display device 6. The sub-assembled head-up display device 6 is installed in the upper part of the instrument panel 2 in this state. In this way, the head-up display device 6 can be easily installed on the upper portion of the instrument panel simply by being assembled so as to be dropped from above the instrument panel 2. For this reason, the operator can perform the assembly work of the head-up display device 6 relatively easily, and can reduce the work load.

  In this state, the upper fixing portion 82 and the lower fixing portion 83 of the support bracket 8 are fastened and fixed to the instrument panel core 26 or the like with the fastening bolts 84 and 85, thereby fixing the head-up display device 6 inside the instrument panel 2. Finally, by attaching the head-up display cover 25 (see FIG. 5) to the instrument panel upper 21, the assembly work of the head-up display device 6 is completed.

  Next, the removal method at the time of service is demonstrated with reference to FIGS.

  As shown in FIG. 8, at the time of service, since the windshield 1 is mounted on the vehicle body, there is almost no space above the instrument panel 2. For this reason, the head-up display device 6 cannot be removed in the sub-assembly state in which the unit main body 7 and the support bracket 8 are integrated. Therefore, only the unit main body 7 is separated from the support bracket 8, and the unit main body 7 is removed using the meter opening 31.

  Specifically, the operator removes the meter device 3 from the rear part of the instrument panel 2, thereby causing the meter opening 31 to appear at the rear part of the instrument panel 2. In addition, as shown in FIG. 8, the instrument panel 31 etc. may also be removed and the meter opening 31 which opened the lower side may be made to appear.

  In this state, first, the operator removes the fastening bolt 25 (see FIG. 7) of the fastening flange portion 74 of the unit main body 7, and then grasps the grip portion 72 of the unit main body 7 from the assembly opening 24. The main body 7 is slid to the rear side of the vehicle body.

  Then, as shown in FIG. 8, the insertion fixing of the insertion rod-like portion 73 and the through-holding hole 88 is released, the unit main body 7 and the support bracket 8 are separated, and only the unit main body 7 can be removed.

  Thereafter, as shown in FIG. 9, the operator changes the posture of the unit body 7 by rotating the unit body 7 downward so that the rear end 7Z of the unit body 7 faces downward. Then, the operator holds the gripper 72 of the unit main body 7 from the meter opening 31 on the rear surface of the instrument panel 2 while maintaining the posture of the unit main body 7.

  Then, as shown in FIG. 10, the operator slides the unit main body 7 obliquely downward and rearward to move the unit main body 7 to a position where the unit main body 7 can be taken out from the meter opening 31.

  At this time, since the dimension I2 between the support bracket 8 and the rear end portion 21Z of the instrument panel upper 21 is set larger than the vertical dimension H2 of the unit body 7, the operator uses the unit body 7 for the meter. It can be slid to a position where it can be taken out from the opening 31.

  Thereafter, as shown in FIG. 11, the operator rotates the unit body 7 again upward so that the rear end 7Z of the unit body 7 is located above the front end 7Y, whereby the unit body 7 Is changed to substantially the same posture as in the state of FIG. By rotating the unit main body 7 in this manner, the unit main body 7 can be easily taken out from the meter opening 31 on the rear surface of the instrument panel 2.

  Then, although not shown, the unit main body 7 can be taken out from the meter opening 31 by sliding the unit main body 7 rearward as it is.

  At this time, since the vertical dimension H3 of the unit main body 7 is set smaller than the vertical dimension I3 of the meter opening 31, the operator can easily take out the unit main body 7 from the meter opening 31. In particular, in this embodiment, since the instrument panel 23 and the like are also removed, a wide opening size can be obtained, and the unit body 7 can be easily removed.

  In this way, at the time of service, only the unit body 7 can be separated from the support bracket 8 and removed from the meter opening 31 on the rear surface of the instrument panel 2, so even if the windshield 1 is mounted above the instrument panel 2, the head up Service workability of the display device 6 can be ensured.

  Note that electrical connection parts such as harness wires and connectors (not shown) are electrically separated in advance before the unit body 7 is separated from the support bracket 8, so that the unit body 7 can be electrically connected. It can be removed without damaging it.

  As described above, according to the mounting structure of the head-up display device 6 of the first embodiment, the head-up display device 6 is attached to the instrument panel 2 via the assembly opening 24 provided on the upper surface of the instrument panel 2 during assembly during manufacture. Although it can be assembled to the upper part of the instrument panel 2 relatively easily from above, the outer dimension H3 of the unit main body 7 is smaller than the dimension I3 of the meter opening 31 for removal at the time of service. The unit body 7 can be removed via the meter opening 31.

  Thus, the head-up display device 6 can be easily assembled with respect to the instrument panel 2 from above without making the assembly opening 24 and the like on the upper surface of the instrument panel 2 so large. The unit main body 7 can be removed from the rear meter opening 31.

  For this reason, the unit main body 7 can be removed without interfering with the front windshield 1 even when the front windshield 1 is mounted above the instrument panel 2 at the time of service.

  Therefore, in the mounting structure of the head-up display device 6 in which the head-up display device 6 is mounted on the top of the instrument panel 2 of the vehicle, the assembly workability at the time of manufacture and the service workability after the manufacture are ensured while ensuring the design freedom of the instrument panel 2. Can be raised together.

(Other embodiments)
As mentioned above, although this invention was demonstrated in Embodiment 1, this invention is not limited to this embodiment.

  For example, in the head-up display device 6, the unit main body 7 to be removed at the time of service may be configured by only the unit main body 7 of the first embodiment even when assembled from above the instrument panel 2. This is because the effects of the present invention can be obtained if the assembly workability can be improved by assembling from the assembly opening 24 on the upper surface of the instrument panel 2 at the time of assembly during manufacture.

  Further, the unit body 7 is not limited to that of the first embodiment as long as the display function of the head-up display device 6 can be recovered by repairing or replacing some parts. For example, a unit configured with an irradiation unit and a control board, or a unit configured with a drive motor, an irradiation unit, and a control board may be used.

  Furthermore, what provides the support bracket 8 is not limited to that of the first embodiment. For example, the support bracket 8 may be composed of a plurality of members instead of a single member, and the material of the support bracket 8 is not limited to resin and may be a metal.

  Further, the meter opening 31 is not particularly limited as long as it is an opening that appears after the meter device 3 is removed and is larger than the outer dimension of the unit body 7.
