Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for an automobile instrument panel, and more particularly to a structure of a cross member that supports a lower end portion of the instrument panel.

[0002]

[Prior Art]

 The applicant of the present application has implemented a technique in which the cross member is divided into left and right parts as shown in FIG. 4 for the purpose of improving the rigidity and weight of the cross member supporting the lower end portion of the instrument panel. It was provided as No. 62-192932.

Here, in the figure, 101 is an instrument panel, and 102 and 103 are left and right divided cross members that support the lower end of the instrument panel 101.

The end portions of the cross members 102 and 103 on the side body side are fixed to the lean hoses 105 mounted on the side body 104 by screws 106, and the end portions on the center side are mounted on the floor tunnel 107. Each of them is fixed to the cement 108 by a screw 109.

The instrument panel 101 has a lower end fixed to the cross members 102 and 103 fixed to the body by screws 110.

[0006]

[Problems to be solved by the device]

 However, in the instrument panel mounting structure having the above-described structure, when the occupant moves forward due to an impact from the front during traveling, the cross member 102 causes the occupant's knee A to move as shown in FIG. There is a concern that the occupant's knee A may enter the instrument panel 101 due to the inability to support the vehicle.

[0007] In order to prevent the above situation, it is possible to improve the mounting rigidity of the cross member 102 at the center side end portion with the floor tunnel 107, but strengthening the mounting bracket is disadvantageous in terms of weight and cost. Not only that, but there was a problem in that the knee A of the occupant was directly impacted.

The present invention has been made in view of the problems of the above-described conventional technology.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a heater unit mounted on the body side near the rear center of the instrument panel with a cross member supporting the lower end portion of the instrument panel, and each of the center side end portions thereof is attached to the heater unit. It is divided into left and right parts with overlapping lengths.The end of each member on the side body side is attached to the inner surface of the side body, and the end on the center side is attached to the floor tunnel, and the lower end of the instrument panel is fixed to the cross member. It has a structure.

[0010]

[Action]

 According to the instrument panel mounting structure of the present invention, the cross member supporting the lower end portion of the instrument panel is mounted on the body side of the heater unit in such a manner that the left and right sides of the center member are overlapped with each other. Since it is divided into two parts and fixed to the body side, even if the occupant moves forward due to the impact from the front while traveling, the cross member abuts on the heater unit behind it and the occupant's knees The occupant's knees can be prevented from entering the instrument panel.

Further, when an excessive impact is applied, the heater unit with which the cross member abuts is deformed to absorb the impact energy and prevent an excessive impact on the knees of the occupant.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is an exploded perspective view showing a mounting structure of an instrument panel according to the present invention, and FIGS. 2 and 3 show a vehicle adopting the mounting structure of an instrument panel according to the present invention from the front. FIG. 4A is a side view and a plan view conceptually showing the state when the impact of FIG.

In FIG. 1, reference numeral 1 denotes an instrument panel, and a center console 2 is provided at a central portion of the instrument panel 1 for the purpose of incorporating a radio and the like. Below the center console 2 is a heater unit 3 mounted on the body side.

Reference numerals 4 and 5 denote cross members for fixing the lower end portion of the instrument panel 1. The cross members 4 and 5 are designed so that their center side end portions 4a and 5a overlap the heater unit 3 mounted on the body side, and are fixed to the body side, respectively.

The cross members 4 and 5 are fixed to the body side through mounting brackets 6, 7 and 8, 9 which are welded and fixed to their ends, respectively. The brackets 6 and 8 welded and fixed to the side body side ends 4b and 5b of the cross members 4 and 5 are welded and fixed to the center side ends 4a and 5a on the inner surface of the side body 14 by screws 10 and 11. The screws 7 and 9 are attached to the upper surface of the floor tunnel 15 by screws 12 and 13, respectively.

The lower end portion of the instrument panel 1 is fixed to the cross members 4 and 5 fixed to the body side by screws 16 and 17, respectively.

Reference numeral 18 denotes an assist grip attached to the instrument panel 1 on the passenger side. The assist grip 18 has one end fixed to the upper end of the bracket 7 of the cross member 4 and the other end attached to the inner surface of the side body 14. It is fixed to the fixed holder member 19 via brackets 20, 21 and 22, 23.

According to the instrument panel mounting structure configured as described above, the cross members 4, 5 supporting the lower end portion of the instrument panel 1 are mounted on the heater unit 3 mounted on the body side. When the occupants move forward due to the impact from the front while traveling as shown in Fig. 2, because the center-side end portions 4a and 5a are divided into left and right halves and fixed to the body side with overlapping lengths. Also, the center side end portions 4a and 5a of the cross members 4 and 5 are in contact with the heater unit 3 behind the cross members 4 and 5 to support the occupant's knees A, and the occupant's knees A can be supported by the instrument panel You can prevent it from entering inside.

Further, when an excessive impact is received, the heater unit 3 with which the cross members 4 and 5 contact as shown in FIG. 3 is deformed to absorb the impact energy, and the knee A of the occupant is absorbed. It is possible to prevent excessive impacts.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. is there.

For example, in the above embodiment, the cross members 4 and 5 are formed of circular pipes. However, the cross member 4 on the passenger side, which does not require so much strength for weight reduction, has a U-shaped cross section. Can be used.

[0023]

[Effect of the device]

 According to the instrument panel mounting structure of the present invention, the cross member supporting the lower end portion of the instrument panel is not firmly fixed to the body side, but the cross member is brought into contact with the rear heater unit. By this, even when the occupant moves forward while receiving a shock from the front, the occupant's knees can be supported and the occupant's knees can be prevented from entering the instrument panel. I can do things.

Further, when an excessive impact is received, the heat unit with which the cross member comes into contact is deformed to absorb impact energy and prevent excessive impact on the knees of the occupant. You can do it.
