The configuration of the vehicle information display device 11 includes a device unit main body member 12 and a unit. It comprises a case member 13 and a bracket member 14 for integrally connecting the unit case member 13 and the device unit main body 12.

First, the structure of the equipment unit main body member 12 will be described.
2 has a front rectangular resin housing 17 for arranging and supporting a display unit 15 such as an LCD and an operation unit 16 provided with a plurality of operation buttons. A positioning rib comprising a horizontal positioning piece 18A extending substantially parallel to the display surface of the display section 15 and a vertical positioning piece 18B formed at an angle to the horizontal positioning piece 18A. 18 is resin-molded integrally with the resin housing 17.

Further, in the vicinity of the positioning rib 18,
Claw 19 for temporarily fixing a bracket member 14 described later
And a screw hole 20 for mounting a bracket.
Further, a metal cover 21 also serving as a shield is attached to the back surface of the resin housing 17.

Next, the structure of the unit case member 13 will be described. The unit case member 13 is formed by press working using a metal plate as a raw material, and a bottom wall 22 positioned in a horizontal direction and a bottom wall 22 are formed. A U-shaped lower case 24 composed of a pair of left and right side walls 23, 23 erected from the left and right side edges, and a metal installed between the upper edges of the lower case 24, that is, between the upper edges of the pair of left and right side walls 23, 23. A circuit board 26 on which a control circuit, electronic components and the like are mounted is mounted in the lower case 24. The circuit board 26 and the device unit main body member 12 are connected to each other by a connector. 40 are connected.

A pair of left and right side walls 2 of the lower case 24
Screw holes 27 for screwing the upper case 25 are provided at appropriate positions in each of the upper case 25 and the lower case 24.
A mounting screw insertion hole 29 is provided for inserting a mounting screw 28 for screwing into the mounting hole.

Next, the bracket member 14 will be described. The bracket member 14 is fixed to the respective outer surfaces of the pair of left and right side walls 23, 23 forming the lower case 24 by means of, for example, spot welding. The brackets 14, 14, which are opposed to the device unit main body member 12, respectively have a contact edge on the lateral positioning piece 18 A and a vertical positioning piece 18 B, respectively. A positioning contact edge 30 is formed, which is composed of a lateral contact edge 30A and a vertical contact edge 30B that are in contact with each other.

In the vicinity of the positioning contact edge 30, a locking hole 31 corresponding to the claw 19 and a screw insertion hole 32 corresponding to the screw hole 20 are formed. Further, the lower edge of the bracket member 14 is
A mounting hole 33 is provided for inserting a mounting screw for screwing the mounting screw into an appropriate portion of a vehicle body or the like.

The structure of each member has been described above. Next, the procedure for assembling the vehicle information display device unit 11 using the above members will be described.
2 on the positioning ribs 18 formed on the left and right side surfaces,
When the positioning contact edges 30 provided on the left and right bracket members 14 are brought into contact with each other, the horizontal positioning pieces 18A and the vertical positioning pieces 18B of the ribs 18 are brought into contact with the horizontal contact edges of the positioning contact edges 30. By assembling so as to be in contact with the 30A and the vertical contact edge 30B, the device unit main body member 12 and the bracket member 14 are guided in a predetermined assembled state without being displaced in the vertical and horizontal directions. . Next, by further pushing, the protrusions are formed on the left and right side surfaces of the device unit main body member 12 in the locking holes 31 formed in the pair of left and right bracket members 14, 14 integral with the unit case member 13. The claw 19 is engaged, and the device unit main body member 12 and the lower case 24 are provisionally positioned, and this state is held with one hand. In this state, the other hand is used to temporarily fix with the mounting screw 28A. That is, the state in which the device unit main body member 12 and the bracket member 14 are positioned is maintained with one hand, and the mounting screw 28A is screwed through the screw insertion hole 32 of the bracket member 14 with the other hand. By screwing into the hole 20, the bracket member 14 integrated with the unit case member 13 can be assembled. A control circuit provided in the lower case 24 and a circuit housed in the device unit main body member 12 are electrically connected via a connector 40.

In this way, the power supply is connected while the electrical connection is being made, and the operation check and adjustment of the circuit and the display surface are performed. This check adjustment and the like can be easily and freely performed without closing the upper case 25.

After the adjustment and checking of the equipment unit are completed, the upper case 2 is inserted into the upper opening of the lower case 24.
5, and the upper case 25 is screwed to the lower case 24 using the mounting screws 28B.
8B is permanently stopped.

The vehicle information display device unit 11 thus assembled is provided with positioning ribs 18 formed on both left and right sides of the device unit main body member 12 and positioning contact edges 30 formed on the bracket member 14. Since the mounting structure is such that the unit body member 12 and the bracket member 14 are positioned relative to each other and then the two members 12 and 14 are screwed together, the assembling dimensional accuracy of the vehicle information display device unit 11 for mass production is made uniform. Therefore, it is expected that the mounting dimensions of each vehicle information display device unit 11 to each vehicle body are made uniform and the mounting accuracy is improved.

The provision of the positioning means comprising the positioning ribs 18 and the positioning contact edges 30 greatly improves the workability of assembling the device unit main body member 12 and the unit case member 13.

Further, since the unit case member 13 can be detached from the upper case 25 while maintaining the unit case member 13 attached to the equipment unit main body member 12, maintenance work or adjustment of the vehicle information display equipment unit 11 can be performed. Can be made easier. Further, since the circuit board 26 on which the electronic circuit and the like are mounted is surrounded by the cover 21 made of metal, the lower case 24 and the upper case 25, the measures against the noise of the electronic circuit and the like are thorough.

[0024]

As described above, according to the mounting structure of the equipment unit of the present invention, the equipment unit main body member and the bracket member mounted on the unit case member are mutually reciprocated between the equipment unit main body member and the bracket member. The provision of positioning means and temporary fixing means for performing temporary positioning between the equipment unit facilitates temporary positioning of the device unit main body member and the bracket member, and greatly improves the workability of temporary assembly. Is done.

Further, since the unit case member is composed of a combination of the lower case and the upper case, it is possible to maintain the assembly of the device unit body member and the unit case member while maintaining the assembly.
The upper case can be attached to and detached from the lower case, and workability such as maintenance and inspection or adjustment of electronic circuits and electronic components incorporated in the lower case can be improved without disassembling the case.
