Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a radiator mounting device.

(Prior art) Conventionally, as a radiator mounting device, for example,
As disclosed in Japanese Patent No. 1-249823, a support hole is provided in the shroud upper provided at the front end of the engine room, and a protrusion provided at the upper end of the radiator is fitted into this support hole. It is known that a radiator is attached between a lower part of a shroud upper and a support portion of a vehicle body side member located below the shroud upper, thereby reducing the space occupied by the radiator in an engine room.

The procedure for assembling the radiator is to fit the protrusion (upper end of the radiator) into the support hole of the shroud upper before installing it to the vehicle body, and then insert the lower end of the radiator into the support hole of the vehicle body side member. It is inserted from above and installed together with the shroud upper. In this case, in order to avoid interference with the radiator inserted from above, the shroud upper should be arranged so that the approximately central part where the upper end of the radiator is located (the part where the support hole is provided) is on both sides of the shroud upper (the part where the radiator is located). The portion (where the upper end is not located) is divided into parts that can be removed with bolts or the like.

In addition, the procedure for assembling a radiator that is different from the one above is to insert the lower end of the radiator into the support part of the car body side member before installing it on the car body, so that the protrusion part aligns with the support hole of the shroud upper. It is inserted and fitted from below. In this case, the shroud upper is not divided into parts but is integrally formed and has high rigidity and strength. In addition, below the car body side member after installing the car body side member,
Under guards etc. will be installed.

(Problem to be Solved by the Invention) However, in the conventional radiator assembly procedure described above, the radiator assembly sometimes involves the installation of a shroud upper or an under guard, etc. These incidental operations make the assembly of the radiator cumbersome.

In addition, in the case where the shroud upper is formed in parts as described above, the rigidity and strength of the shroud upper are undeniably lowered, and therefore, it is necessary to increase the strength of the shroud upper itself, which is disadvantageous in terms of weight and cost. It ends up.

The present invention uses the above-described integrally formed shroud upper with high rigidity, and in order to avoid interference with the shroud upper, even if the radiator is inserted in an inclined state from diagonally above the shroud upper, the lower end of the radiator The objective is to improve the workability of assembling the radiator by improving the lower end of the radiator and the support part of the car body side member so that the lower end part of the radiator can be easily inserted into the support part of the car body side member. shall be.

In addition, improvements were made to the shroud upper so that the protrusion at the upper end of the radiator can be easily fitted from the direction of the integrally formed shroud upper, thereby improving the workability of assembling the radiator. The purpose is to

(Means for Solving the Problem) In order to achieve the above object, the means taken by the invention according to claims (1) and (2) are such that the radiator is inserted and attached to the lower part of the shroud upper from a predetermined direction. It is assumed that the radiator mounting device is

It is attached to an upper mount bracket extending to the upper mount bracket, and both sides of the notched recess are connected by the upper mount bracket.

(Function) With the above configuration, in the invention according to claim (1), in order to avoid interference with the shroud upper when assembling the radiator, the lower end of the radiator is inserted from diagonally above the shroud upper in an inclined state. The shroud upper is connected to the hole of the lower mount bracket from diagonally above the shroud upper by the spherical mount member provided at its lower end and the approximately circular hole of the lower mount bracket provided on the vehicle body side member. The upper end of the radiator is attached to the shroud upper when the radiator is assembled. Incidental work such as upper installation work and under guard installation work is eliminated, making it possible to improve the workability of assembling the radiator. Furthermore, since the shroud upper is integrally formed, the shroud upper has high rigidity and strength, and safety in the event of a collision is ensured.

Further, in the invention according to claim (2), in order to avoid interference with the shroud upper when assembling the radiator, the upper end of the radiator is inserted into the support portion of the vehicle body side member from diagonally above the shroud upper and becomes inclined. The protrusion (upper mount bracket) on the shroud upper has a cutout recess that is recessed in the direction in which the radiator is mounted, that is, in the direction of rotation of the protrusion of the radiator with the lower end of the radiator as a fulcrum, and a notch that is recessed in the direction of rotation of the protrusion of the radiator with the lower end of the radiator as a fulcrum. The mounting of the radiator with the protrusion of the The radiator can be easily inserted into the notched recess recessed in the rotational direction of the protrusion, thereby improving the workability of assembling the radiator. Furthermore, when installing the radiator, the sides of the notch recess that are recessed in the direction of installation of the radiator are
Since they are connected by an upper mount bracket that extends in a direction perpendicular to the recessed direction of the notched recess, the upper mount bracket effectively suppresses the decrease in rigidity of the shroud upper due to the provision of the notched recess. This ensures sufficient safety in the event of a collision.
