Description

  The present invention relates to a front structure of an automobile, and more particularly to a resin shroud, a hood that covers an upper part of an engine room, and a heat exchanger that has a refrigerant inlet and is supported by the shroud. .

  Conventionally, as a front structure of an automobile, a structure in which a seal member for sealing between an inner panel of a bonnet and an upper portion of a shroud supporting a heat exchanger is provided. This seal member prevents hot air in the engine room from flowing forward from the heat exchanger and rain and the like from entering the engine room (see Patent Document 1).

  By the way, in general, at the time of manufacturing an automobile, as shown in FIG. 14, a coolant inlet is provided to radiators 301 and 401, which are one of the heat exchangers, using a predetermined coolant injector (not shown). The refrigerant is injected through 301a and 401a.

  Here, as shown in FIGS. 14A and 14B, the size of the radiators 301 and 401 (the heights of the main bodies 301b and 401b of the radiators 301 and 401, depending on the type of the engine, such as a diesel engine or a gasoline engine). May be different).

  However, from the viewpoint of the productivity of the shroud 302, a plurality of types of shrouds are not manufactured according to the above-described engine type (difference in the height of the radiator body), and all of them are common to the large-sized radiator 301. Things are used. The lower portions of the radiators 301 and 401 are both aligned and attached to the lower portion 321 of the shroud 302 that supports the radiators 301 and 401.

  Further, the length (projection amount) L extending from the main bodies 301b and 401b of the radiators 301 and 401 is unified as short as possible for the refrigerant inlets 301a and 401a regardless of the sizes of the radiators 301 and 401. Has been. If there is variation in the length L, a large-capacity packing material is required for a long one when the parts constituting the refrigerant inlets 301a and 401a are conveyed. As a result, the number that can be loaded on the conveying means is reduced, leading to a decrease in conveying efficiency.

  Therefore, when the radiators 301 and 401 having different sizes are attached to the same type of shroud 302, the height positions (projection amounts) of the refrigerant inlets 301a and 401a are different by ΔL as shown in the figure.

By the way, the refrigerant injector can be connected to the refrigerant inlets 301a and 401a by gripping their tips. And the refrigerant | coolant injection machine can supply a refrigerant | coolant reliably by the operation | movement within the range of the work area WA shown with a dashed-two dotted line.
Japanese Utility Model Publication No. 6-73272

  Here, in the case of FIG. 14B showing the large radiator 401, the height position of the refrigerant inlet 401a is set to be the same as or slightly higher than the upper end of the upper portion 323 of the shroud 302, and the work area WA Since it does not overlap with the upper part 323, the refrigerant injector and the refrigerant inlet 401a can be connected.

  However, in the case of FIG. 14A showing the other small radiator 301, the refrigerant inlet 301a is positioned below the upper end of the upper portion 323 of the shroud 302, so that the refrigerant injector and the refrigerant inlet 301a In order to enable the connection, it is necessary to devise the upper portion 323.

  Therefore, as indicated by a two-dot chain line in FIG. 14A, in consideration of the range of the work area WA, the position where the refrigerant inlet 301a is disposed in the upper portion 323 of the shroud 302 is different from other positions. It is conceivable to form a recess 323a that is recessed downward to allow connection to the refrigerant inlet 301a of the refrigerant injector.

  Here, when the concave portion 323a is formed, in order to seal between the bonnet and the upper portion 323, an uneven seal member 305 matching the shape of the concave portion 323a as shown in FIG. I need it. However, the sealing member 305 having such an uneven shape is disadvantageous from the viewpoint of sealing performance.

  The present invention provides a front portion of an automobile that can perform a refrigerant injection operation at the time of manufacturing a vehicle and can maintain a sealing performance between an upper portion of a shroud and a bonnet while suppressing a protruding amount of a refrigerant inlet of a heat exchanger. The purpose is to provide a structure.

  The front structure of the automobile of the present invention has a resin shroud composed of an upper portion, both side portions, and a lower portion, a bonnet that covers the upper portion of the engine room, and a refrigerant inlet, and is supported by the shroud. A heat exchanger, and the upper portion of the shroud is formed with a recess recessed below the other position at the position where the refrigerant inlet is disposed, and the refrigerant inlet is connected to the heat exchanger body. The shroud includes a cover member that covers the recess, and a seal member is disposed in a gap between the shroud and the bonnet, and the seal member is disposed on the cover member. It is provided along the line.

  According to this configuration, even if the heat exchanger is small, the concave portion of the upper portion enables the refrigerant injection operation during vehicle manufacture while suppressing the amount of protrusion of the refrigerant inlet of the heat exchanger. Furthermore, a sealing member with small unevenness can be provided by the cover member.

  In an embodiment of the present invention, the upper surface of the heat exchanger main body is formed so that the portion of the refrigerant inlet is the highest, and the shroud is disposed in the vicinity of the portion that is lowered away from the refrigerant inlet. A duct opening portion is formed in the upper portion of this.

  According to this configuration, the duct can be disposed using the empty space formed in the vertical direction by the lower portion of the upper surface of the heat exchanger, and the opening area of the duct opening can be secured large. .

  Furthermore, since the refrigerant inlet is disposed at a position relatively higher than other portions of the upper surface of the heat exchanger, the amount of depression of the concave portion of the upper portion can be suppressed as much as possible.

  In one embodiment of the present invention, the cover member forms an opening with the recess.

  According to this configuration, since the opening of the intake duct member, the through hole through which the cable passes, and the like can be formed without making an opening in the shroud, the moldability of the shroud can be improved.

  In one embodiment of the present invention, the upper portion of the shroud is formed with an intake inlet opening portion to which a duct member for taking in air in front of the seal member of the cover member is formed by the recess. One of the first cover member and the second cover member that does not form the intake introduction opening can be selectively attached to the recess.

  According to this configuration, since the shroud can be shared regardless of the presence or absence of the duct member, the productivity of the shroud can be improved.

  In one embodiment of the present invention, a lock device that locks the bonnet in a closed state is provided, and an opening for passing a cable related to the lock device into the engine room is an intake introduction opening of the duct member. It is formed integrally.

  According to this configuration, since the through hole through which the cable passes can be formed without making an opening in the shroud, the moldability of the shroud can be improved. Furthermore, since the air intake introduction part of the duct member and the through hole of the cable are made common by the air intake introduction opening part, the number of processing parts formed in the cover can be reduced, and the moldability of the cover member itself is improved. Can be made.

  In one embodiment of the present invention, the cover member is detachable from the shroud.

  According to this configuration, it is possible to easily perform maintenance of the cover member itself, maintenance of members around the cover member, or the like.

  According to this invention, even if the heat exchanger is small, the coolant injection operation at the time of vehicle manufacture becomes possible while suppressing the protrusion amount of the coolant inlet of the heat exchanger by the recess of the upper portion. Furthermore, since the cover member can provide a sealing member with small irregularities, the sealing performance between the upper portion of the shroud and the bonnet can be maintained.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
First, the first embodiment shown in FIGS. 1 to 9 will be described. FIG. 1 is a perspective view of a structure of a radiator and a shroud in a front structure of an automobile as seen from the front, and FIG. In the drawing, the arrow (F) indicates the front of the vehicle, and the arrow (R) indicates the rear of the vehicle.

  In FIG. 1, reference numeral 1 denotes a radiator, which is mainly disposed at a longitudinal end of a radiator core (not shown) composed of a plurality of radiator tubes (not shown) through which a coolant such as cooling water flows, and the radiator tubes. This is a known heat exchanger composed of a radiator tank (not shown) that communicates with each radiator tube. Reference numeral 1a denotes a refrigerant inlet 1a for injecting a refrigerant into the radiator 1 in the automobile manufacturing process, and is connected to the main body 1b of the radiator 1.

  The radiator 1 is supported by a resin shroud 2 having a substantially rectangular frame shape. The shroud 2 is mainly composed of a lower portion 21, both side portions 22, and an upper portion 23. The upper portion 23 is formed with a recess 23a that is recessed below other positions at the position where the refrigerant inlet 1a is disposed. ing.

  In addition, a duct opening 24 to which the tip opening of the first duct 3 is connected is formed at a portion where the upper end surface of the upper portion 23 is high. The first duct 3 performs intake air for operating an engine (not shown) located behind the radiator 1.

  The shroud 2 is provided with a detachable cover 4 that covers the front part of the recess 23a. The height of the upper surface of the cover 4 is substantially the same as the height of other parts of the shroud 2 other than the recess 23a. It is said that.

  Reference numeral 5 denotes a seal member that extends in the vehicle width direction along a part of the upper surface of the upper portion 23 of the shroud 2 and the upper surface of the cover 4 that have substantially the same height as described above. Yes.

  In the present embodiment, as shown in FIG. 2, an opening edge 41 is formed in the cover 4, and when the cover 4 is attached to the upper part 23, the opening edge 41 and the upper part 23 are The opening 6 is formed by the mounting portion 23b having a further concave shape in the concave portion 23a. And the opening 6a of the 2nd duct 7 is connected to this opening 6 so that the air ahead of the sealing member 5 can be taken in. The bottom surface of the second duct 7 is fixed to the surface of the mounting portion 23b.

  The second duct 7 is provided as appropriate when it is necessary to perform intake air having a purpose different from the intake air for operating the engine, such as cooling of a central control unit (CPU) constituting a control unit (not shown) of the vehicle. Is. For example, depending on the type of engine and the like, the control unit may be laid out at a position that is easily affected by heat generated from the engine. In such a case, cooling means for the control unit is required. Therefore, the CPU can be cooled by providing the second duct 7 and blowing the air sucked in front of the radiator 1 to the vicinity of the control unit.

  In the upper portion 23, the bonnet locking device 8 is located in front of the cover 4. The bonnet locking device 8 is disposed so as to be accommodated in a pocket portion 25 of an upper portion 23 formed in front of the cover 4.

  Here, the members 9 and 10 extending from the bonnet locking device 8 are a latch release wire and a latch harness, which will be described in detail later. The end of the latch release wire 9 is connected to a driver's seat (not shown) in the passenger compartment. On the other hand, the latch harness 10 passes through the space 6a of the opening 6 other than the tip opening 7a of the second duct 7, passes behind the radiator 1, and is finally connected to the control unit of the vehicle. Has been. That is, the opening for the tip opening 7 a of the second duct 7 and the opening as the through hole of the latch harness 10 are integrally formed by the opening edge 41.

  Here, the manufacturing process of the front structure of the automobile according to the present embodiment will be described with reference to FIGS.

  FIGS. 3 and 4 are a front view and a rear view, respectively, showing the refrigerant injection operation for the radiator 1. WA shown with the dashed-two dotted line in the figure is a work area of the refrigerant | coolant injection machine which supplies a refrigerant | coolant to the radiator 1 in this refrigerant | coolant injection | pouring operation | work. In the manufacturing process of the front structure of an automobile, the coolant is supplied to the radiator 1 by connecting the tip of a coolant injector (not shown) that requires a work area WA indicated by a two-dot chain line in the drawing to the coolant inlet 1a.

  As shown in FIG. 4, the refrigerant inlet 1 a is formed at the distal end portion of the tubular body that protrudes upward from the upper part on the back side of the radiator body 1 b, and in the state where the radiator 1 is supported by the shroud 2 as shown in the figure. The height is set so as to protrude slightly from the upper surface of the upper portion 23 in front view.

  Here, the radiator 1 in this embodiment uses a small body as the main body 1b, and the refrigerant inlet 1a is located below the upper surface of the upper portion 23. As described above, the shroud 2 is used. Even if the coolant inlet 1a is positioned below the upper surface of the recess 23a by forming a recess 23a that is recessed from the other at the position where the coolant inlet 1a of the upper portion 23 is disposed, During the refrigerant injection operation, the tip of the refrigerant injector and the refrigerant inlet 1a can be connected, and the refrigerant can be reliably supplied to the radiator 1.

  In addition, even if the main body 1b of the radiator 1 to be used is large, it is possible to use the shroud 2 in which the concave portion 23a is formed in the upper portion 23, except that the height position of the refrigerant inlet 1a is slightly increased. There are no differences. Therefore, the recess 23 does not hinder the refrigerant injection operation. That is, the shroud 2 can be shared regardless of the size of the radiator 1 (main body 1b) to be used. Thereby, the productivity of the shroud 2 is improved.

  By the way, as shown in FIG. 4, the upper surface of the radiator 1 rear side is formed so as to be inclined so that the portion of the refrigerant inlet 1a is the highest and becomes lower as the distance increases. Further, the duct opening 24 described above is formed in the upper portion 23 of the shroud 2 at a position away from the portion where the refrigerant inlet 1a is disposed.

  As described above, by forming the duct opening 24 in the upper portion 23 in the vicinity of the portion where the upper surface of the radiator 1 is lowered, the empty space formed in the vertical direction by the lower portion of the upper surface of the radiator 1 is used. Thus, the first duct 3 can be disposed, and a large opening area of the duct opening 24 can be secured.

  In other words, it can be said that the refrigerant inlet 1 a is relatively higher than other portions of the upper surface of the radiator 1. Therefore, as a result, the amount of the recess 23a of the upper portion 23 of the shroud 2 is suppressed as much as possible.

  By the way, in the process of attaching the cover 4 shown in FIGS. 1 and 2, the substantially L-shaped member shown in FIG. 5 is attached to the recess 23a. As shown in FIGS. 5A and 5B, a substantially L-shaped engaging portion 42 is integrally formed on one end side of the cover 4, and on the inner side surface on the other end side, FIG. As shown to b), the clip 43 which protrudes from the inner surface of the cover 4 is integrally formed. Reference numeral 44 in the figure denotes a small second opening edge that is preliminarily formed for passing an appropriate signal line (so-called harness), a power transmission cable, and the like. It is the reinforced panel part provided.

  The cover 4 shown in FIG. 5 is first positioned by engaging the engaging portion 42 of the cover 4 with the engaged portion 26 of the shroud 2 shown in FIG. 6 (a cross-sectional view taken along line AA in FIG. 2). After that, the cover 4 can be attached by fitting the clip 43 on the other end side into the fitting hole 27 of the shroud 2. For this reason, the clip 43 and the fitting hole 27 can be easily fitted and detached, and the cover 4 can be easily attached and detached. Since the cover 4 can be easily attached and detached, the cover 4 itself can be maintained. In addition, maintenance of peripheral members of the cover 4 such as the first duct 3, the latch release wire 9, and the latch harness 10 can be easily performed.

  After the cover 4 is attached in this way, as described above, a part of the upper surface of the upper portion 23 of the shroud 2 and the upper surface of the cover 4 are substantially the same in height. A long seal member 5 is attached along the line. When the bonnet 11 is closed by the cover 4 and the seal member 5 as shown in FIG. 7 (cross-sectional view taken along the line B-B in FIG. 2 when the bonnet 11 is closed), the upper portion of the shroud 2 23 and the bonnet 11 are sealed.

  Even when the radiator 1 is small in size due to the configuration of the concave portion 23a of the upper portion 23 of the shroud 2, the cover 4, and the seal member 5 as described above, the refrigerant at the time of vehicle manufacture can be suppressed while suppressing the amount of protrusion of the refrigerant inlet 1a. Since the coolant injection operation into the injection port 1a can be performed and the seal member 5 with small unevenness can be provided by the cover 4, the bonnet 11 is closed between the upper portion 23 and the bonnet 11. Seal performance can be maintained.

  By the way, as shown in FIG. 7, the bonnet 11 is mainly comprised from the outer panel 11a and the inner panel 11b. A striker 12 that engages with the hood lock device 8 on the shroud 2 side and locks the closed state of the hood 11 is attached near the tip of the inner panel 11b. In FIG. 7, a space En behind the radiator 1 represents an engine room.

  Here, based on FIG. 8, FIG. 9, the structure and effect | action of the bonnet lock apparatus 8 in this embodiment are demonstrated. 8 and 9 are a front view and a rear view, respectively, of the bonnet locking device 8. The bonnet locking device 8 mainly includes a first latch 84, a spring 85, A second latch 88, a lock plate 89, a latch release wire 9, and springs 91 and 92 are pivotally attached to the pivots 86 and 87.

  Here, when the bonnet 11 (see FIG. 7) is opened, the latch release wire 9 is connected to a bonnet lock release lever (not shown) in the passenger compartment. 9, the lock plate 89 engaged with the stopper 90 is rotated clockwise against the tensile force of the spring 91 in FIG. 9. As a result, the engagement between the engagement claw 89a of the lock plate 89 and the engagement claw 88a of the second latch 88 is released, so that the second latch 88 is counterclockwise about the pivot 86 by the tensile force of the spring 92. To turn. Thereby, the opening side of the engaging grooves 81a and 82a of the bases 81 and 82 is opened, the striker 12 is unlocked, and the hood 11 is opened.

  At this time, since the bonnet 11 is in a half-open state, the first latch 84 is rotated by rotating the operation piece 84a of the first latch 84 shown in FIG. 8 counterclockwise against the tensile force of the spring 85. Is completely retracted from the engaging grooves 81a and 82a, the bonnet 11 can be fully opened.

  8 and 9, reference numeral 13 denotes a detection unit for detecting the position of the second latch. The detection lever 13a can be brought into contact with the second latch 88, and the position of the detection lever 13a is indicated by a two-dot chain line. And a signal output unit 13b for outputting a detection signal when displaced.

  The detection unit 13 is connected to the vehicle control unit via the latch harness 10, the second latch 88 is rotated counterclockwise in FIG. 9, and the detection lever 13 a is pushed by the second latch 88. When the detection lever 13a is displaced to the position of the two-dot chain line, the detection signal is output by pressing a push button (not shown) of the signal output unit 13b including a limit switch, for example.

  Therefore, by monitoring the state of the second latch 88 by the detection unit 13, it is possible to detect whether or not the hood 11 has been opened illegally, and the detection result is output to the control unit via the latch harness 10. Can be done.

  Here, as shown in FIG. 1, the latch harness 10 is passed through a portion of the space 6 a other than the tip opening 7 a of the second duct 7 in the opening 6 and into the engine room En (see FIG. 7). Has been passed. In this way, the opening edge 41 is formed in the cover 4 and the opening 6 is formed with the recess 23a, so that the shroud 2 is opened when the second duct 7 is attached or cables are passed. Therefore, the moldability of the shroud 2 can be improved.

  In particular, in the present embodiment, the intake portion of the second duct 7 and the through hole of the latch harness 10 are shared by the opening 6. For this reason, the number of the recessed parts formed in the cover 4 is reduced, and the moldability of the cover 4 itself is improved. Moreover, since the space | interval between recessed parts can be expanded by reducing the number of the recessed parts formed in the cover 4, the part which becomes weak between recessed parts can be reduced.

(Second Embodiment)
Next, a second embodiment shown in FIGS. 10 and 11 will be described. FIG. 10 is a view showing the cover 104 and is a perspective view showing (a) the outer side surface and (b) the inner side surface, respectively. FIG. 11 is a perspective view of an essential part showing a portion where the cover 104 shown in FIG. 10 is attached in the front structure of the automobile. In addition, the same code | symbol is attached | subjected about the component similar to 1st Embodiment, and the description is abbreviate | omitted.

  In the first embodiment described above, when the second duct 7 for performing intake air having a purpose different from that for operating the engine, such as cooling of a control unit (not shown), is provided, the opening 6 is formed by the shroud 2 and the cover 4. However, depending on the specifications of the vehicle, such as the type of engine, there are some that do not require the cooling action described above. Therefore, in the cover 104 of this embodiment, instead of the opening edge portion 41 formed in the first embodiment, the cover 104 is notched so as to be large enough to pass the latch harness 10 shown in FIG. An opening edge 141 is formed. That is, the portion where the second duct 7 of the opening edge portion 41 in the first embodiment is attached is also used as a cover surface, and the cover surface is attached so as to fit the attachment portion 23 b of the shroud 2.

  Since the opening edge portion 141 can provide an opening having a minimum size that allows the latch harness 10 to pass therethrough, there is no useless opening portion. Therefore, the hot air on the engine room En side can be prevented from leaking forward from between the mounting portion 23b of the shroud 2 and the opening edge portion 141 of the cover 104.

  Also in the cover 104 of the second embodiment, as in the first embodiment, a substantially L-shaped engagement portion 142 is formed on one end side of the cover 104, and on the inner surface on the other end side, A clip 143 protrudes from the inner side surface of the cover 104, and further, a small second opening edge portion 144 and a reinforcing panel portion 145 are formed.

  As described above, the concave mounting portion 23b is formed in the upper portion 23 of the shroud 2 in advance, so that the second duct 7 and the second duct 7 can be used regardless of the presence or absence of the second duct 7 (engine specifications, etc.). Either the cover 4 to be attached or the cover 104 when the second duct 7 is not present can be alternatively attached to the upper portion 23 of the shroud 2. As described above, by enabling the selective attachment of the covers 4 and 104, the shroud 2 can be shared, so that the productivity of the shroud 2 can be improved.

(Third embodiment)
Next, a third embodiment shown in FIGS. 12 and 13 will be described. FIG. 12 is a front view of the bonnet lock device 208, and FIG. 13 is an enlarged view of a main part showing a portion where the bonnet lock device 208 shown in FIG. In addition, the same code | symbol is attached | subjected about the component similar to 1st Embodiment, and the description is abbreviate | omitted.

  The layout of the bonnet locking device may be a plurality of patterns in consideration of easiness of wiring and the like, depending on the layout of the vehicle, a predetermined standard, and the like.

  That is, depending on the layout and specifications of the vehicle, as shown in FIG. 12, a bonnet lock device 208 that is symmetrical to the bonnet lock device 8 of the first embodiment may be attached.

  In this case, the bonnet locking device 208 is similar to the bonnet locking device 8 of the first embodiment in that the latch release wire 209, the detection unit 213, the base 281, the pivots 283, 286, 287, the first and second latches 284, 288. , A spring 285, a lock plate 289, and a stopper 290, but the left and right arrangements of the latch release wire 209, the detection unit 213, the first and second latches 284, etc. are opposite to the bonnet lock device 8 in the vehicle width direction Become a relationship.

  Therefore, as shown in FIG. 13, the wiring of the latch release wire 209 and the latch harness 210 can be passed in the opposite direction in the vehicle width direction as compared with the case of the first embodiment shown in FIG.

  In the present embodiment, the latch harness 210 connected to the detection unit 213 that detects whether or not the hood 11 has been opened illegally extends in the vehicle width direction toward the second opening edge 44 of the cover 4. Here, it is possible to pass through the opening formed by the preliminarily formed second opening edge 44 and the shroud 2 and into the rear engine room En.

  On the other hand, since the latch release wire 209 extends toward the opening 6 in the vehicle width direction, the latch release wire 209 can be passed through the portion of the space 6a of the opening 6 and into the rear engine room En.

  Accordingly, the opening 6 has a role of passing the latch release wire 209 in addition to the latch harness 10 and can be a through hole for passing any cable related to the bonnet lock device.

(Fourth embodiment)
In the third embodiment described above, the latch release wire 209 is assumed to be passed through the opening 6 common to the tip opening 7a of the second duct 7. However, for example, the specification does not require the second duct 7. In the case of the cover 104, the cover 104 formed with the opening edge 144 (see FIGS. 10 and 11) described in the second embodiment is used. In this case, the latch release wire 209 can be passed through the rear engine room En by passing through the opening formed by the opening edge 141 and the shroud 2 that are cut out in a small size.

(Other embodiments)
In the above-described embodiment, the latch release wires 9 and 209 and the latch harnesses 10 and 210 are cited as the cables related to the bonnet locking device, but the present invention is not necessarily limited to this. For example, a switch means is provided in the driver's seat instead of the bonnet lock release lever, and when a passenger operates the switch means, an electrical signal is output to the hood lock device by a harness, and the striker 12 is unlocked by driving an appropriate actuator. It may be done.

  Further, the present invention can be applied even if the detectors 213 and 213 shown in the above-described embodiments are not provided.
