[Industrial applications]

 According to the present invention, a pin is integrally formed on a thin plate body made of resin, and an engaging hole into which the pin is fitted is formed in a fixed member provided on one surface side of the thin plate body. The present invention relates to a member mounting structure in which a fixed member is fixed to a thin plate member by crushing a tip portion of a pin in a state where the fixed member is fitted into the engaging hole of the fixed member.

[0002]

[Prior Art]

 This kind of member mounting structure is applied to, for example, a lens mounting structure of a dial plate of an automobile meter.

That is, in a conventional automotive meter, as shown in FIG. 5, a pointer 3 arranged on a dial 2 is provided in a meter case 1 incorporated in an instrument panel in front of a driver. Various indicator instruments 4 such as a speedometer unit which is driven by an instrument unit (not shown) fixed to the rear surface of the dial plate 2 are accommodated, and the character of the indicator instrument 4 is displayed on the front surface of the meter case 1. A look-back plate 5 is provided to mask the inside of the meter case 1 except for the plate 2 so that the driver cannot see it.

Further, various warning lights 6 such as an oil warning light and a parking brake warning light are arranged at predetermined positions of the dial plate 5, and the warning light 6 is provided on the rear surface of the dial plate 5. It is formed of a lens 7 fixed to the lens 7 and a lamp (not shown) arranged behind the lens 7 and turned on and off according to predetermined information. A decorative frame 8 is formed on the surface of the dial plate 5 around the warning light 6 by a process such as hot stamping.

Conventionally, when attaching the lens 7 of the warning light 6 to the dial plate 5, as shown in FIGS. 6 and 7, the pin 9 is integrally formed at a predetermined lens mounting position on the rear surface of the dial plate 5. On the other hand, the lens 7 of the warning lamp is provided with an engagement hole 10 into which the pin 9 is inserted. Then, after engaging the engagement hole 10 of the lens 7 with the pin 9 of the dial plate 5, the tip end of the pin 9 is crushed by means such as welding or cold staking, so that the dial plate 5 can be formed. The lens 7 is fixed to the rear surface.

[0006]

[Problems to be solved by the device]

 However, in the above-described conventional member mounting structure, for example, when the thickness of the dial plate 5 is 0.8 mm, the diameter of the pin 9 is formed in substantially the same manner. Since the diameter of the pin 9 is extremely small, the strength of the pin 9 is extremely weak, and the pin 9 may not be deformed when the engaging hole 10 of the lens 7 is engaged with the pin 9, and the pin 9 is also deformed. There is a problem in that the fixing force of the lens 7 due to is extremely weak and inconveniences such as the dislocation of the lens 7 occur.

Therefore, it is conceivable to form the diameter of the pin 9 large. However, when the diameter of the pin 9 is formed large as described above, when the dial plate 5 and the pin 9 are integrally molded with resin or the like, As shown in FIG. 8, the shrinkage of the resin 11 occurs on the surface of the dial plate 5 in the portion where the pins 9 are formed due to the heat shrinkage that occurs when the resin is cooled, and this shrinkage 11 causes the deformation of the surface of the dial plate 5. As a result, the flatness of the surface of the dial plate 5 deteriorates and the external appearance of the dial plate 5 is extremely deteriorated. Further, the hot stamping of the surface of the dial plate 5 for forming the decorative frame 8 around the warning light 6 is performed. There is a problem that it becomes impossible to properly perform such processing.

The present invention has been made in view of the above points, and it is possible to prevent shrinkage or the like from occurring on the surface of the pin forming portion of the thin plate made of resin, and moreover, to fix the pin to the pin. It is an object of the present invention to provide a member mounting structure capable of increasing the fixing strength of a fixed member to be fixed.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the member mounting structure according to claim 1 of the present invention is such that a pin is integrally formed on a thin plate body made of resin, and a fixed member is disposed on one surface side of the thin plate body. An engaging hole into which the pin is inserted is bored, and the tip of the pin is crushed in a state where the pin is inserted into the engaging hole of the fixed member to fix the fixed member to the thin plate member. In the member mounting structure, the pin is formed in a tubular shape, and the tip end portion of the pin is bent to fix the fixed member in a state where the pin is fitted and inserted in the engagement hole of the fixed member. It is characterized by having done.

Further, in the member mounting structure according to claim 2 of the present invention, a pin is integrally formed on a thin plate made of resin, and the pin is attached to a fixed member disposed on one surface side of the thin plate. A member mounting in which an engaging hole into which is inserted is formed, and the tip of the pin is crushed in a state where the pin is inserted into the engaging hole of the fixed member to fix the fixed member to the thin plate body. The structure is characterized in that a plurality of the pins are formed and the engagement holes are formed as long holes into which at least two of the pins are fitted.

[0011]

[Action]

 According to the invention of claim 1, since the pin is formed in a cylindrical shape and the fixed member is held by the circumference of the tip end portion of the pin, it is possible to secure a large pin strength, The holding strength of the fixing member is significantly increased, and it is possible to reliably prevent the fixed member from coming off.In addition, by forming the pin into a cylindrical shape, the substantial diameter of the pin can be increased. Since it is intended to increase the thickness of the pin and does not increase the thickness of the pin, resin shrinkage does not occur on the surface of the pin forming part of the thin plate, and there is no deformation and a surface with good flatness. It is possible to obtain a thin plate body provided with a pin for fixing a clean fixed member.

According to the second aspect of the invention, since the fixed member is fixed by the plurality of pins, the holding strength of the fixed member can be remarkably increased, and the fixed member is fixed. Since it is possible to reliably prevent the occurrence of slippage of the pin, and because the pin itself is not formed to have a large diameter, resin shrinkage etc. may occur on the surface of the pin forming part of the thin plate. In addition, since a plurality of pins are engaged with the engaging elongated holes, the pins can be reliably engaged with the engaging elongated holes even when the pin forming position is inaccurate. Is something that can be done.

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a lens mounting structure of a return plate of an automotive meter to which an embodiment of a member mounting structure according to the present invention is applied. In this embodiment, the lens mounting structure is arranged in front of the meter case. A cylindrical pin 9 having a large diameter and a hollow inside is integrally formed at a predetermined lens mounting position on the rear surface of the dial plate 5, and the diameter of the pin 9 is, for example, When the thickness of the dial plate 5 is 1 mm, it is about 3 mm. Further, the lens 7 of various warning lights such as an oil warning light and a parking brake warning light is provided with an engagement hole 10 into which the pin 9 is inserted.

Next, the lens fixing means according to the present embodiment will be described. In this embodiment, after the pin 9 of the dial plate 5 is engaged with the engaging hole 10 of the lens 7, the tip of the pin 9 is welded by a jig 12 such as a chisel as shown in FIG. Alternatively, the tip portion of the pin 9 is bent outward by caulking, whereby the lens 7 is fixed to the look-back plate 5.

Therefore, in the present embodiment, since the diameter of the pin 9 is formed large, the strength of the pin 9 can be ensured to be large, and when the engagement hole 10 of the lens 7 is inserted into the pin 9, the pin 9 can be inserted. It is possible to reliably prevent the pin 9 from being deformed. Moreover, since the pin 9 is formed in a cylindrical shape and the lens 7 is held by the periphery of the tip of the pin 9, the holding strength of the lens 7 is significantly increased, and the lens 7 is reliably prevented from coming off. can do. Further, by forming the pin 9 in a cylindrical shape, the diameter of the pin 9 is substantially expanded, and the thickness dimension of the pin 9 is not expanded. When the resin is integrally molded with a resin or the like, shrinkage of the resin does not occur on the surface of the dial plate 5 in the portion where the pin 9 is formed, and the dial plate 5 having a clean appearance without deformation of the dial plate 5 is formed. Therefore, hot stamping or the like on the surface of the dial plate 5 for forming the decorative frame around the warning light can be properly performed.

In the above embodiment, the case where the tip portion of the pin 9 is welded in an annular shape has been described, but as shown in FIG. 3, it is welded in a square shape, a hexagonal shape or the like depending on the shape of the jig. You may do it.

Therefore, also in the present embodiment, as in the above-described embodiment, the lens 7 is fixed by the plurality of pins 9, so that the holding strength of the lens 7 can be remarkably increased and the lens 7 is dislocated. Since the pin 9 itself is not formed to have a large diameter, resin shrinkage does not occur on the dial plate 5 and the dial plate 5 is prevented. It is possible to obtain the facing plate 5 having a clean appearance and no deformation.

Further, for example, if one engagement hole is made to correspond to one pin 9, the pin 9 and the engagement hole may not be engaged due to the positional accuracy of the pin 9 and the engagement hole. However, in the present embodiment, since the plurality of pins 9 are engaged with the engaging long holes 13, the pins can be surely engaged with the engaging long holes 13 even when the pin forming position is not accurate. Can be engaged with.

The present invention is not limited to the above-described embodiment, but can be widely applied to a portion where a fixed member is attached to a pin of a thin plate, and a fixed member such as a lens can be applied. The present invention can be applied to not only the fixing pin but also the positioning pin, and various changes can be made as necessary.
