Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to a structure for mounting a fan shroud of an automobile radiator and a metal fitting for mounting the radiator.

[0002]

[Prior art]

 In a conventional fan shroud mounting structure for a radiator, core supports are arranged at both ends of a radiator core composed of fins and tubes, and an arm of the fan shroud is fixed to the core support via bolts and nuts. To mount the radiator itself in the engine room, a separate radiator mounting bracket was provided on its core support.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to provide a radiator fan shroud mounting structure that can easily mount a fan shroud and omit a radiator mounting bracket.

[0004]

[Means for Solving the Problems]

 In the fan shroud mounting structure of the radiator of the present invention, a fan shroud 2 is disposed opposite to a radiator core 1, and a tip end of a support arm 4 of the fan shroud 2 is provided on a core support 3 disposed at both ends of the radiator core 1. In a fan shroud mounting structure for a radiator, a pair of locking holes 5 are formed on both sides of the core support 3 made of a metal plate bent in a groove shape so as to be aligned with each other. A locking pin which is integrally formed with the support arm 4 at a position corresponding to the locking pin 5 and which is inserted into the locking hole 5 and which is integrally formed with a claw 6a for preventing the tip from coming off. 6 and a support holding member formed in parallel with the locking pin 6 to protrude integrally with the tip of the support arm 4 and bridged between the edges of the pair of groove-like side walls of the core support 3. And a mounting pin 8 for mounting a radiator integrally protruding from an outer surface of the support holding portion 7 in a direction orthogonal to the locking pin 6. It is characterized in that the distance from the base of the locking pin 6 is substantially equal to the width of the core support 3.

According to the fan shroud mounting structure of the radiator, the fan shroud 2 can be fixed to the core support 3 with one touch by the locking pin 6 of the support arm 4 of the fan shroud 2, and the support arm 4 can be fixed to the support arm 4. The radiator can be mounted on a vehicle or the like by the projecting mounting pins 8. For this reason, the conventionally required fasteners for the fan shroud and the metal fittings for mounting the radiator become unnecessary.

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a fan shroud mounting structure of the radiator, and FIG. 2 is a sectional view taken along the line II-II of FIG. In this radiator, a pair of tanks 9 are located left and right apart from each other, and both ends of a large number of flat tubes 10 are fixed to the respective tanks 9 in a liquid-tight manner. Corrugated fins 11 are joined between the flat tubes 10. The radiator core 1 is constituted by the large number of flat tubes 10 and the corrugated fins 11, and the core support 3 is fixed to the upper and lower ends of the radiator core 1. The core support 3 is made of a metal plate whose cross section is bent in a groove shape except for both ends in the longitudinal direction, and a pair of locking holes 5 aligned with each other are formed on both sides of the core support 3. I have. Two pairs of such a pair of locking holes 5 are arranged apart from each other in the longitudinal direction of the core support 3.

Next, the fan shroud 2 is made of a synthetic resin injection molded body, and connects the cylindrical portion 12 with a motor mounting portion 13 disposed at the center thereof, and connects the motor mounting portion 13 with the cylindrical portion 12. A plurality of stays 15 and a support arm 4 arranged on an extension of the stay 15 are integrally formed. An end plane of the support arm 4 is aligned with the plane of the core support 3, and a locking pin 6 is integrally provided at a position aligned with the locking hole 5 of the core support 3. At the tip of the locking pin 6, a claw portion 6a for retaining is formed. The position of the claw portion 6a is formed at a position equal to or slightly longer than the width of the core support 3. The fan shroud 2 has some elasticity. The tip of the support arm 4 is bent at a right angle, and the support holding portion 7 is provided there. The projecting length of the support holding portion 7 is slightly longer than the width of the core support 3. On the upper surface of the support holding portion 7, a mounting pin 8 is integrally provided to project orthogonally to the locking pin 6.

The locking pins 6 of the fan shroud 2 thus configured are pressed into the locking holes 5 of the respective core supports 3. At this time, after the claw 6a is slightly deformed and passes through the locking hole 5, the support arm 4 is fixed to the core support 3 by the presence of the claw 6a. At the same time, the support holder 7 is seated on the upper surface of the core support 3. A mounting pin 8 is integrally formed on the upper surface of the support holding portion 7, and the mounting pin 8 is fitted and supported on a support material (not shown) in a trunk room of an automobile or the like. In this example, the lower pair of support arms do not have the support holding portion 7 and the mounting pin 8, but they can be provided. Next, a fan (not shown) is mounted in the cylindrical portion 12, and a boss of the fan is fixed to a rotating shaft of a motor (not shown). The motor is mounted on the motor mounting portion 13 via fasteners such as bolts.

[0009]

[Functions and effects of the invention]

 In the fan shroud mounting structure of the radiator of the present invention, since the locking pin 6 and the mounting pin 8 are integrally formed on the support arm 4 of the fan shroud 2, the number of parts is reduced and the assembling property is improved. Becomes That is, by inserting the locking pin 6 of the support arm 4 into the pair of locking holes 5 of the core support 3, the claw 6 a at the tip of the locking pin 6 is locked to the edge of the locking hole 5. The fan shroud 2 is attached to the core support 3. The radiator can be mounted in an engine room of a vehicle or the like by the mounting pins 8 protruding from the support holding portion 7 of the support arm 4. Therefore, it is possible to eliminate the conventionally required fastener for mounting the fan shroud and the metal fitting for mounting the radiator.
