Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of a mounting structure in which a radiator, which is a heat exchanger of an automobile, and a condenser of an air conditioner are attached to a vehicle body.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 3 and 4, pins 41a and 42a are provided on both sides of the upper and lower portions of the radiator 4a, and are attached to the vehicle body by a dedicated mounting member 10a via a rubber bush 6a. Also, pins 31a and 32a are provided on both upper and lower sides of the capacitor 3a, and are attached to the vehicle body by a dedicated mounting member 10b via a rubber bush 6b. The attachment member 10a to the vehicle body above the radiator and the attachment member 10b to the vehicle body above the capacitor are separate bodies.
[0003]
The radiator 4a and the capacitor 3a can give suitable vibration characteristics by changing the characteristics of the rubber bushes 6a and 6b.
[0004]
However, the attachment members 10a and 10b have a structure in which an elastic material is attached to a hole provided at one end, the elastic material is inserted into the radiator or capacitor pins 41a and 31a, and the other end is fastened with a screw. Therefore, when the radiator or capacitor pins 41a and 31a are inserted into the holes of the mounting members 10a and 10b, the mounting members 10a and 10b are supported at one point, and thus the posture is not stable.
[0005]
In addition, the mounting members 10a and 10b are unstable because they try to move in the rotation direction of the screw at the time of screw fastening, and workability is poor because they cannot be released. A structure such as temporary fixing was necessary.
[0006]
Further, the mounting members 10a and 10b, which are separately provided for the radiator and the capacitor, have a problem that workability during mass production is poor because the parts are small.
[0007]
Another conventional heat exchanger mounting structure for automobiles has a structure in which a radiator and a condenser are integrated in advance and attached to the vehicle body in order to improve the mounting property to the vehicle body (for example, patents) Reference 1). However, the rubber bush must be tuned to the specified resonance frequency, and the condenser will vibrate together with the radiator that actively vibrates as a dynamic damper to reduce vehicle vibration, so the condenser piping must be flexible. As a result, there was a problem of increasing costs.

A lower pin 42 is provided. The upper pins 31 and 41 are pins protruding upward, and the lower pins 32 and 42 are pins protruding downward. The upper pin 41 of the radiator 4 is longer than the upper pin 31 of the capacitor 3.
[0028]
The lower cross member 21 of the radiator core support member 2 is provided with lower mounting holes 211 and 212 for mounting the capacitors 3 and the lower pins 32 and 42 of the radiator 4 via the rubber bushes 62 and 64, and the radiator core support member 2. A mounting hole 22 for mounting the upper bracket 5 is provided in the upper portion of the.
[0029]
In this embodiment, the capacitors are juxtaposed in front of the radiator and attached to the radiator core support member 2.
[0030]
The upper bracket 5 is a plate-like member and has a substantially U shape. Further, the lengths on both sides are different, and the longer one is the radiator upper holding portion 52 and the shorter one is the capacitor upper holding portion 51. The radiator upper holding portion 52 and the capacitor upper holding portion 51 are provided in parallel. Therefore, the attachment surfaces of the radiator upper holding portion 52 and the capacitor upper holding portion 51 to the upper pins 31 and 41 are parallel to each other. The radiator upper holding portion 52 is provided with an engagement hole 521 for attaching the rubber bush 63, and the capacitor upper holding portion 51 is provided with an engagement hole 511 for attaching the rubber bush 61. The engagement holes 521 and 511 are provided so as to be oriented in parallel holes.

[0031]
The rubber bushes 61, 62, 63, 64 are annular and have a through hole for attaching a pin at the center. In particular, the rubber bush 64 is tuned to a predetermined resonance frequency. The rubber bushes 61 and 62 have a large elastic coefficient, and the rubber bushes 63 and 64 have a small elastic coefficient.
[0032]
Next, the operation will be described.
[0033]
[Mounting work for automotive heat exchanger mounting structure]
[0034]
In the mounting operation in the heat exchanger mounting structure of this embodiment, first, the rubber bushes 62 and 64 are inserted into the lower mounting holes 211 and 212 respectively provided on both sides of the lower cross member 21 of the radiator core support member 2. The rubber bush 64 is pre-tuned to a predetermined resonance frequency. Next, the lower pin 32 of the capacitor 3 is inserted into the hole portion of the rubber bush 62, the lower pin 42 of the radiator 4 is inserted into the hole portion of the rubber bush 64, and the lower portion of the capacitor 3 and the radiator 4 is connected to the lower cross member 21. Install.
[0035]
A rubber bush 61 for the upper pin 31 of the capacitor 3 is inserted into the engagement hole 511 of the upper bracket 5, and a rubber bush 63 for the upper pin 41 of the radiator 4 is inserted and attached to the engagement hole 521. .
[0036]
Since the capacitor 3 and the radiator 4 with the lower part attached to the lower cross member 21 are juxtaposed at a predetermined interval, the state can be easily maintained with one hand. In this state, the upper bracket 5 to which the rubber bushes 61 and 63 are attached is held with the other hand. At this time, since the upper bracket 5 has an appropriate size, it is easy to grasp.
[0037]
Next, the upper pin 41 of the radiator 4 longer than the upper pin 31 of the capacitor 3 is inserted into the hole portion of the rubber bush 63 attached to the engagement hole 521 of the upper bracket 5, and the rubber bush 61 attached to the engagement hole 511. The upper pin 31 of the capacitor 3 is inserted into the hole portion, and the upper pin 41 of the radiator 4 is inserted into the hole portion.
[0038]
Since the insertion into the upper pins 31 and 41 is not simultaneous, the operator can easily perform the insertion.
[0039]
At this time, since the engagement holes 511 and 521 of the upper bracket 5 are parallel and the hole portions of the rubber bushes 61 and 63 are also parallel, the upper pins 31 and 41 of the capacitor upper holding portion 51 and the radiator upper holding portion 52. The mounting direction is the same.
[0040]
Moreover, since the attachment surface to the upper pins 31 and 41 of the capacitor | condenser upper holding part 51 and the radiator upper holding | maintenance part 52 is also parallel, an operator should just handle it as the same mounting direction.
[0041]
Therefore, when the upper bracket 5 is mounted, the upper bracket 5 is attached to the capacitor 3 and the radiator 4 by a movement of inserting the upper bracket 5 in one direction from top to bottom.
[0042]
Moreover, since the operator who works from the front has the capacitor | condenser 3 smaller than the radiator 4, this is easy to confirm visually.
[0043]
Next, the screw hole 531 provided in the central attachment portion 53 of the upper bracket 5 and the attachment hole 22 of the radiator core support member 2 are fastened with the attachment screw 7. As a result, it is possible to reduce the number of fastening portions of the mounting screws that have been conventionally required for mounting the upper portions of the capacitor and the radiator, and the mounting work can be made more efficient.
[0044]
In addition, the pin projecting direction of the upper pins 31 and 41 is the vertical direction, and the axial direction of the mounting screw 7 is the front-rear direction, and therefore has a phase difference of about 90 degrees in the front-rear rotation direction. Even if the upper bracket 5 tries to rotate, it is restricted by the attachment via the rubber bush, so that the attachment position does not shift. Furthermore, since the upper bracket 5 is a single member, it can be easily held by hand so as not to rotate. Therefore, the mounting work can be easily performed by using the upper bracket 5 as one member.
[0045]
Similarly, the upper bracket 5 is also attached to the other left and right upper portions of the capacitor 3 and the radiator 4, and the mounting of the capacitor 3 and the radiator 4 to the radiator core support member 2 is finished.
[0046]
[Use of radiators for dynamic dampers]
[0047]
The rubber bush 64 is tuned to a predetermined resonance frequency. Since the rubber bushes 61 and 62 have a large elastic coefficient and the rubber bushes 63 and 64 have a small elastic coefficient, the radiator 4 vibrates with a larger amplitude than the capacitor 3. The radiator 4 can be used as a mass of the dynamic damper.
[0048]
Next, the effect will be described.
[0049]
In the mounting structure of the automobile heat exchanger of the embodiment, the effects listed below can be obtained.
[0050]
(1) The radiator 4 having upper pins 41 on both upper sides and the lower pins 42 on both lower sides, and the capacitor 3 having upper pins 31 on both upper sides and lower pins 32 on both lower sides are juxtaposed in the front-rear direction. In the mounting structure of the heat exchanger of an automobile, the lower pin 42 and the lower pin 32 are inserted into the radiator core support member 2 via the rubber bushes 64 and 62, and the radiator 4 and the condenser 3 are mounted on the radiator core support member 2. A radiator upper holding portion 52 engaged with the upper pin 41 via a rubber bush 63 and held at a predetermined position; and a capacitor upper holding portion engaged with the upper pin 31 via a rubber bush 61 and held at a predetermined position. The upper bracket 5 composed of 51 and the mounting portion 53 is formed as a single member, and the upper portion of the radiator 4 and the upper portion of the capacitor 3 are the upper bracket. The radiator core support member 2 is attached to the radiator core support member 2 with the rack 5, so that the posture of the radiator and the capacitor during the mounting work can be stabilized, and the mounting tool itself during the mounting work is supported by two points, so that the rotation is stopped. Since the number of parts is reduced, the number of attachment points is reduced, and the size is easy to be grasped by an operator, the work can be made efficient and the work can be facilitated.
[0051]
(2) Since the mounting direction in which the radiator upper holding portion 52 is engaged with the upper pin 41 and the mounting direction in which the capacitor upper holding portion 51 is engaged with the upper pin 31 are the same mounting direction, the upper direction to the lower direction can be achieved. Since the radiator 4, the capacitor 3, and the upper bracket 5 can be attached in one direction, workability is improved.
[0052]
(3) The upper pins 31, 41 are inserted into the rubber bushes 61, 63 by providing engaging holes 511, 521 for attaching the annular rubber bushes 61, 63 in the radiator upper holding portion 52 and the capacitor upper holding portion 51 in parallel. Thus, since the radiator 4, the capacitor 3 and the upper bracket 5 can be attached in one direction from the upper side to the lower side, workability is improved.
[0053]
(4) Since the mounting surface of the radiator upper holding portion 52 to the upper pin 41 and the mounting surface of the capacitor upper holding portion 51 to the upper pin 31 are made parallel, the operator is placed above the upper pins of the capacitor 3 and the radiator 4. It is easy to match the bracket 5.
[0054]
(5) Since the upper pin 41 of the radiator 4 is longer than the upper pin 31 of the capacitor 3, the upper bracket 5 can be sequentially inserted from the radiator side, so that it can be easily mounted and workability is improved.
[0055]
(6) Since the capacitor 3 is mounted in front of the radiator 4, the operator can work while visually confirming, so that workability is further improved.
[0056]
(7) Since the mounting portion 53 of the upper bracket 5 is attached to the radiator core support member 2 by fastening the mounting screw 7, the protruding direction of the upper pin 41 and the upper pin 31 and the axial direction of the mounting screw 7 are different directions. The mounting position does not shift and the mounting work can be performed easily.
[0057]
As mentioned above, although the mounting structure of the heat exchanger of the motor vehicle of this invention was demonstrated based on the Example, about a specific structure, it is not restricted to an Example, The invention which concerns on each claim of a claim Design changes and additions are permitted without departing from the gist of the present invention.
[0058]
For example, in the embodiment, the upper bracket 5 is made of resin, but may be made of metal. In addition, the mounting portion 53 of the upper bracket 5 to the radiator core support member 2 is mounted with the mounting screw 7 in the embodiment, but a bolt and nut may be fastened as a screwed body, and the mounting may be performed by welding. There may be.
[0059]
In the embodiment, one side of the upper portion of the radiator 4 and the upper portion of the capacitor 3 is attached to the radiator core support member 2 by a single upper bracket 5, but both the upper portion of the radiator 4 and the upper portion of the capacitor 3 are attached to the upper bracket of one member. 5 may be a structure that is attached to the radiator core support member 2.
[0060]
Further, it is assumed that slight angle deviations that do not affect the operational effects of the present invention are in the category of parallelism.

[0065]
In the application example, unlike the upper bracket 5 of the embodiment, one of the upper brackets 5 has a concave shape that is bent in the middle of a substantially U-shape, but the capacitor upper holding part 51 and the radiator upper holding part 52 are Since the structure connected by the attaching part 53 is the same, the code | symbol is made the same.
