Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle heat exchanger mounting structure for mounting a heat exchanger such as a radiator or a condenser mounted on a vehicle to a vehicle body.

[0002]

[Prior Art]

 Conventionally, a vehicle has a radiator that radiates the heat generated by the engine through the engine cooling water, and a condenser (condenser) that cools and liquefies the high-temperature and high-pressure refrigerant that is compressed by the compressor in the cooling system. ) Is installed. These radiators and capacitors are, as described in Japanese Utility Model Laid-Open No. 57-62122, a rubber insulator formed of an elastic body such as rubber in order to reduce the influence of vibration generated by the running of the vehicle. It is attached to the cross member, upper rail, etc. of the vehicle body via a vehicle vibration isolator such as mount rubber.

When a capacitor is attached using such a conventional vehicle vibration isolator, as shown in FIG. 7, first, a rubber insulator 113 as a vehicle vibration isolator is easily attached to the bracket 115 in advance. Attach it so that it does not come off. Further, the rubber insulator 113 is attached to the upper part of the capacitor 20 by fitting the capacitor support on the upper part of the capacitor 20 into the holding groove provided on the lower surface of the rubber insulator 113.

Next, the capacitor 20 having the rubber insulator 113 mounted thereon is placed on the lower mount 40 (see FIG. 1), and the main harness 31 and the airbag harness 33 arranged inside the upper rail 30 are placed inside the upper rail 30. While holding the bracket 115 so that it is stored, the bracket 115 is pressed from the outside of the upper rail 30, and during this time, the bolt 117 is inserted into the nut attached by welding from the inside of the upper rail 30 and screwed to the bracket 115 so as to be screwed. I fixed it to 30.

In addition, in the example shown in FIGS. 8 to 10, a bracket 215 is welded to the capacitor support 21 above the capacitor 20, and a cutout 215 a provided in the bracket 215 is provided with a rubber sleeve for vibration isolation. 205 was fitted, a bolt 217 with a washer was inserted into the bolt hole 205a of this sleeve 205, and screwed together to fix the bracket 115 to the upper rail 30.

[Problems to be solved by the device]

 However, as described above, when mounting the capacitor to the vehicle body via the upper rail, the bolt holes formed in the bracket and the upper rail are aligned while holding the relatively heavy capacitor, and Inserting and screwing in causes the capacitor to fall in the direction of arrow B, which makes the screwing operation difficult and causes a drop in workability.

The present invention has been made in view of the above circumstances, and is for a vehicle capable of preventing the radiator and the condenser from collapsing, facilitating the attachment of the radiator and the condenser to the vehicle, and improving the workability. The present invention relates to a heat exchanger mounting structure.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the invention of the present application is to provide a holding member that is provided on an upper portion of the heat exchanger in a mounting structure of a vehicle heat exchanger that is fixed between an upper rail and a lower mount of the vehicle, and a holding member. A vehicle vibration isolator made of an elastic material, which is interposed between a member and the heat exchanger, and has a protrusion protruding above the holding member and having a length capable of engaging with the upper rail. When the heat exchanger mounted on the mount is mounted from the front of the vehicle, the protrusion is temporarily hooked on the upper rail to fix the holding member to the upper rail.

[0009]

According to the present invention, when the heat exchanger mounted on the lower mount is mounted from the front of the vehicle, the projecting portion projecting upward from the upper portion of the heat exchanger is projecting at a length capable of engaging with the upper rail. Therefore, the protrusion hits the lower side of the upper rail. When pushed in, since the protrusion is made of an elastic material, it bends and passes under the upper rail, and the heat exchanger can be positioned under the upper rail. Further, when fixing the heat exchanger to the upper rail, the holding member provided on the upper portion of the heat exchanger is fixed to the upper rail in a state in which the protrusion is hooked on the upper rail.

【Example】

 An embodiment according to the present invention will be described below with reference to the drawings. The present invention relates to a vehicle heat exchanger mounting structure for mounting a radiator mounted on a vehicle or a condenser mounted in front of the radiator to a vehicle body.

First, the schematic shape of the rubber insulator 1 as a vibration isolator will be described with reference to the perspective view of FIG.

The rubber insulator 1 is a molded product made of rubber having a predetermined elasticity, and two deep grooves 7a and 7b are provided on the lower surface side of the main body 3. The groove spacing and groove depth of the deep grooves 7a and 7b are appropriately determined in accordance with the shape of the capacitor support 21 on the capacitor 20.

The lip 5 is erected on the upper side surface of the rubber insulator body 3 substantially at the center thereof. The lower portion of the lip 5 has a substantially truncated cone shape, and the upper portion of the truncated cone has a cylindrical shape. Further, a constriction 5a for engaging with the bracket 11 is formed on the lower side of the truncated cone. The height of the constriction 5a, that is, the gap distance between the upper surface of the main body and the lower surface of the truncated cone is slightly smaller than the plate thickness of the bracket 11, and the diameter of the lower surface of the truncated cone is slightly smaller than the hole diameter of the lip hole 13a of the bracket 11. The diameter of the connecting portion between the main body and the truncated cone is large and is substantially equal to the diameter of the lip hole 13a of the bracket 11. Therefore, when the bracket 11 is attached to the rubber insulator 1, the lip 5 of the rubber insulator 1 is made to penetrate through the lip hole 13a of the bracket 11, so that the bracket 11 can be easily separated from the rubber insulator 1. ..

Next, the configuration of the bracket 11 will be described with reference to FIGS. 3 and 4. The bracket 11 is composed of a lower bracket 13 for holding the rubber insulator 1 and an upper bracket 15 for attaching to the upper rail 30, and the lower bracket 13 and the upper bracket 15 are integrally formed by spot welding. Is fixed so that. Further, the lower bracket 13 is provided with a lip hole 13a corresponding to the lip 5, and the upper bracket 15 is provided with a bolt hole 15a corresponding to a bolt 17.

Next, with reference to FIGS. 1 to 6, a procedure for mounting the capacitor 20 on a vehicle using the rubber insulator 1 and the bracket 11 described above will be described.

First, the lip 5 of the rubber insulator 1 is passed through the lip hole 13 a of the bracket 11, and the rubber insulator 1 is attached to the bracket 11 beforehand so as not to be easily separated. Further, by inserting the capacitor support 21 above the capacitor 20 into the deep holding grooves 7a and 7b provided on the lower surface of the rubber insulator 1, as shown in FIG. 20 Install on top.

Next, as shown in FIG. 1, the capacitor 20 to which the rubber insulator 1 is attached is placed on the lower mount 40, and the main harness 31 and the airbag harness 33 arranged inside the upper rail 30 are arranged inside the upper rail 30. The capacitor 20 is once erected on the lower mount 40 while being housed in.

Next, the worker pushes the capacitor 20 until it is located below the upper rail 30 in order to mount the capacitor 20 from the front of the vehicle. At this time, since the lip 5 made of an elastic material is largely bent as shown in FIG. 5, the lip passes below the lower end portion of the upper rail 30 and is pushed into the upper rail 30.

Since the lip 5 pushed into the upper rail 30 is hooked on the inner wall of the upper rail 30, the condenser 20 is prevented from falling down in the forward direction, and the operator is prevented from tilting. Release the hand that had been gripped on and move to the screwing operation of the bolt.

Further, the bolt 17 is inserted into a nut that is attached by welding from the inside of the upper rail 30, and screwed to fix the bracket 11 to the upper rail 30.

After the installation, the lip 5 presses and holds the main harness 31 and the airbag harness 33 arranged in the upper rail 30 against the inner wall on one side of the upper rail 30. Also, it is possible to suppress the fluttering of the harnesses caused by the vibration generated by the traveling of the vehicle.
