Description

  The present invention relates to a mounting structure for a cementer.

  Patent Document 1 discloses a vehicle in which a engine is provided in an engine room. The cementer is disposed on a fuel supply passage connecting the fuel tank and the engine, and separates and stores moisture mixed in the fuel. The cementer is attached to a suspension tower which is a member constituting the engine room. The attachment structure of the cementer has a support member fixed to the side wall of the suspension tower. By storing the cementer in the support member, the cementer is attached to the suspension tower. In the attachment structure of the cementer described in Patent Document 1, the cementer is attached to the rear side of the vehicle on the inner side surface of the suspension tower in the vehicle width direction. Thus, in the engine room, the cementer is disposed obliquely behind the engine.

JP 2010-115995 A

  When the vehicle collides from diagonally forward, the engine disposed in the engine room moves diagonally backward. Therefore, even in the case where the segmenter is disposed obliquely behind the engine as in the case of the attachment structure described in Patent Document 1, there is a possibility that the engine and the cementer interfere with each other at the time of a vehicle collision. For this reason, the mounting structure of the cementer described in Patent Document 1 is not necessarily an optimal configuration from the viewpoint of protecting the cementer in the event of a vehicle collision, and there is still room for improvement.

  A mounting structure of a cementer for solving the above-described problem is a mounting structure of a cementer that attaches a cementer to a suspension tower, which is a member constituting an engine room of a vehicle, via a supporting member. And having a peripheral wall surrounding the side surface of the cementer over the entire circumference, one of the side wall in the vehicle width direction of the suspension tower and the peripheral wall of the support member is provided with a locking piece, The other side is provided with a locking part for locking the locking piece, and the locking member and the locking part are locked, and the support member and the suspension are fastened by bolting at one point. A tower is connected, the strength of the support member is higher than the strength of the suspension tower, and the strength of the locking portion is higher than the strength of the locking piece. High.

  The engine housed in the engine room may move toward the suspension tower to which the cementer is attached due to a vehicle collision. In this case, when the engine interferes with the support member storing the cementer, the support member is pressed against the suspension tower. In the above configuration, since the strength of the support member is higher than the strength of the suspension tower, the suspension tower is more actively deformed and receives an impact caused by a vehicle collision. Therefore, the shape of the support member is easily maintained, and deformation of the cementer is suppressed. In addition, the engine may move to the side of the suspension tower where the cementer is not attached due to a vehicle collision. In this case, the engine and the support member do not interfere with each other, but other members housed in the engine room may interfere with the support member. In the said structure, the intensity | strength of a latching | locking part is high in the latching | locking part and latching piece which latches the support member and the suspension tower. Therefore, when another member interferes with the support member due to a vehicle collision, the locking piece is deformed by the load, and the engagement between the locking portion and the locking piece is released. As a result, the support member can rotate relative to the suspension tower with the bolt as a rotation center, and rotates so as not to be crushed when interfering with other members. Therefore, according to the above configuration, the protection function of the cementer at the time of a vehicle collision can be improved.

  One embodiment of the attachment structure of the cementer will be described with reference to FIGS. In each figure, “Fr” is the front side of the vehicle, “Rr” is the rear side of the vehicle, “RH” is the right hand side in the vehicle width direction toward the front of the vehicle, and “LH” is the left hand side in the vehicle width direction toward the front of the vehicle. The upper side of the vehicle is indicated by “Upr” in the direction of the arrow.

  As shown in FIG. 1, an engine room 10 that houses an engine 100 is provided at the front of the vehicle. The vehicle has a bumper frame 11 provided at the front end of the vehicle as a member constituting the engine room 10. The bumper frame 11 extends in the vehicle width direction. A pair of front side members 12 that are spaced apart in the vehicle width direction are connected to the bumper frame 11. The front side member 12 extends in the vehicle front-rear direction, and a dash panel 13 is connected to a rear end portion thereof. The dash panel 13 extends in the vehicle width direction. The engine room 10 and the vehicle compartment 110 are partitioned by the dash panel 13.

  The vehicle also has a suspension tower 14 which is a member constituting the engine room 10. The suspension towers 14 are arranged in pairs in a state of being separated from each other in the vehicle width direction, and are positioned at the left suspension tower 14 </ b> A located diagonally rearward on the left hand side of the engine 100 and the diagonally rearward side of the right hand side of the engine 100. It consists of a right suspension tower 14B. Each suspension tower 14A, 14B is configured by a plate-shaped steel material (for example, SPC270 material). Each suspension tower 14A, 14B has a rear end portion connected to the dash panel 13, and an outer end portion in the vehicle width direction is connected to a vehicle body frame constituting the vehicle. Each of the suspension towers 14A and 14B includes an upper wall 15 in which an opening 15A is formed, a front wall 17 connected to the upper wall 15 and positioned on the vehicle front side, and connected to the upper wall 15 and positioned on the inner side in the vehicle width direction. And a lateral wall 18. A flange 19 is provided at the lower ends of the front wall 17 and the lateral wall 18. The flange 19 is connected to the front side member 12. The suspension of the vehicle is held by the suspension towers 14A and 14B. In the engine room 10, an actuator 120 of a brake device and the like are disposed on the vehicle front side of the left suspension tower 14A. A cowl grille 20 extending in the vehicle width direction is connected to the upper end of the dash panel 13 so as to cover the rear ends of the suspension towers 14A and 14B from above.

  One end of a fuel supply passage 130 is connected to the engine 100. The other end of the fuel supply passage 130 is connected to a fuel tank. A fuel pump is disposed on the fuel supply passage 130. By driving the fuel pump, the fuel in the fuel tank is sucked into the fuel supply passage 130 and supplied to the engine 100. A cementer 50 is also disposed on the fuel supply passage 130. As shown in FIG. 2, the cementer 50 includes a separation unit 51 and a pump unit 52 provided at the upper end of the separation unit 51. The separation part 51 is formed in a hollow cylindrical shape, and houses a water-repellent filter therein. As shown by solid line arrows in FIG. 2, the fuel flowing through the fuel supply passage 130 is once supplied to the separation unit 51 of the segmenter 50, passes through the filter in the separation unit 51, and then returns to the fuel supply passage 130 again. . Since water mixed in the fuel cannot pass through the filter, it is separated from the fuel and stored in the separation unit 51. A drain plug 53 is provided at the lower end of the separation portion 51. By removing the drain plug 53, the water stored in the separation part 51 is discharged to the outside as indicated by the one-dot chain line arrow in FIG. The pump unit 52 can be pushed down with respect to the separation unit 51. When the pump unit 52 is pushed down, fuel is sucked up from the fuel tank into the fuel supply passage 130. When air is mixed into the fuel supply passage 130 and the fuel pump cannot suck up the fuel from the fuel tank, the pump unit 52 is operated to suck up the fuel up to the fuel pump. Thereby, the startability of engine 100 is improved. As shown in FIG. 1, the cementer 50 is attached to the left suspension tower 14A.

  As shown in FIG. 3, the cementer 50 is housed in a cylindrical support member 60 and attached to the left suspension tower 14 </ b> A via the support member 60. The support member 60 includes a plate-like back wall 61 and a curved wall 62 having a U-shaped cross section connected to the back wall 61, and has a substantially D-shaped cross section. The back wall 61 is formed so as to extend upward from the curved wall 62, and has an arc shape so that the upper end surface thereof is positioned below both end portions. The support member 60 has an inner diameter at the lower end portion that is smaller than the outer diameter of the separation portion 51 of the segmenter 50, and an inner diameter at the upper end portion that is greater than the outer diameter of the separation portion 51. The support member 60 forms a peripheral wall that surrounds the side surface of the cementer 50 over the entire circumference by the back wall 61 and the curved wall 62. The support member 60 is made of a steel material (for example, SPC440 material) having higher strength than the steel material constituting the suspension tower 14. Therefore, the strength of the support member 60 is higher than the strength of the suspension tower 14.

  As shown in FIGS. 4A and 4B, the back wall 61 of the support member 60 is provided with locking portions 40 at both ends in the width direction. The locking portion 40 is formed by cutting out the back wall 61. As shown in FIG. 4A, the notch extends upward in the width direction (left-right direction in FIG. 4A) and has an L shape in a front view. This L-shaped notch has a predetermined depth length. The inner side of the cutout extends outward in the width direction so that the back side thereof leaves the front side portion of the back wall 61. Therefore, as shown in FIG. 4B, the cutout has an L-shape in which a portion on the back side (right side of FIG. 4B) of the back wall 61 extends upward in a side view. . Due to this notch, the support member 60 is provided with a locking portion 40 as an integral part of the back wall 61. As shown in FIGS. 4A and 4B, the back wall 61 is provided with a through hole 61 </ b> A in a region extending upward from the curved wall 62.

  As shown in FIG. 3, a substantially cylindrical first projecting base 21 and second projecting base 22 projecting inward in the vehicle width direction are formed on the vehicle front side of the lateral wall 18 of the left suspension tower 14 </ b> A. The end surface of the first protruding base 21 is substantially elliptical, and two columnar protruding pins 23 are provided side by side on the end surface. The 2nd protrusion stand 22 is located under the 1st protrusion stand 21, and the end surface is substantially circular shape. One columnar protruding pin 24 is provided on the end surface of the second protruding base 22. Male threads are formed on the outer peripheral surfaces of the projecting pins 23 and 24.

  The left suspension tower 14 </ b> A has a plate-like attachment plate 30 attached to the lateral wall 18. The mounting plate 30 has a rectangular plate-shaped substrate portion 30A. 300 A of insertion holes are formed in the board | substrate part 30A in the position corresponding to each said protrusion pin 23,24. The projecting pins 23 and 24 respectively corresponding to the insertion holes 300A provided in the board portion 30A are inserted, and the mounting plate 30 is fixed to the front side of the lateral wall 18 by attaching the nut 70 to the projecting pins 23 and 24. The In the left suspension tower 14 </ b> A, the side wall 18 and the mounting plate 30 constitute a side wall on the inner side in the vehicle width direction. A bent plate portion 30B is connected to the upper end of the substrate portion 30A. The bent plate portion 30B extends inward in the vehicle width direction from the upper end of the substrate portion 30A, and the tip end portion is bent upward. In the bent plate portion 30B, a support hole 300B is formed in a portion bent upward.

  The attachment plate 30 is provided with a pair of locking pieces 41. The locking pieces 41 are provided at both ends of the board portion 30A in the vehicle front-rear direction. Each locking piece 41 extends inward in the vehicle width direction from the board portion 30 </ b> A, and is bent and extended in the vehicle front-rear direction so as to be separated from each other. Thus, the locking piece 41 is provided on the side wall in the vehicle width direction of the suspension tower 14A. In addition, the locking piece 41 is configured as an integral part of the mounting plate 30 and is made of the same steel material as the steel material constituting the suspension tower 14.

  As shown in FIGS. 5A and 5B, the locking piece 41 provided on the mounting plate 30 is assembled to the locking portion 40 through the notch of the support member 60. That is, by inserting the locking piece 41 into the notch from the near side to the back side of the back wall 61 and sliding the support member 60 downward with respect to the locking piece 41, The locking piece 41 is locked. As shown in FIG. 5B, the bent plate portion 30 </ b> B of the mounting plate 30 is in contact with the back wall 61 of the support member 60 in a state where the locking piece 41 is locked to the locking portion 40. In this state, the bolt 80 is inserted into the through hole 61A of the support member 60 and the support hole 300B of the mounting plate 30, and the nut 81 is assembled to the bolt 80, whereby the support member 60 and the mounting plate 30 are rotated relative to each other. It is bolted so that it can move. As described above, in the above-described mounting structure of the cementer 50, the locking plate 41 is provided on the mounting plate 30 that forms the side wall in the vehicle width direction of the left suspension tower 14 </ b> A, and the back wall 61 that forms the peripheral wall of the support member 60. The latching | locking part 40 is provided in this. The mounting plate 30 is fixed to the vehicle front side of the lateral wall 18. Then, the supporting member 60 is connected to the left suspension tower 14A by locking the locking piece 41 and the locking portion 40 and bolting the mounting plate 30 and the supporting member 60 to each other at one point. The support member 60 is disposed on the vehicle front side on the side wall in the vehicle width direction of the left suspension tower 14A. As described above, the strength of the steel material constituting the support member 60 is higher than the strength of the steel material constituting the mounting plate 30, that is, the steel material constituting the suspension tower 14. Therefore, the strength of the locking portion 40 provided as an integral part with the support member 60 is higher than the strength of the locking piece 41 provided as an integral part with the mounting plate 30.

The effect of this embodiment is demonstrated with reference to FIGS.
(1) As shown in FIG. 6, when the vehicle collides with the obstacle 200 from the diagonally forward right, the obstacle 200 interferes with the right front portion of the engine 100. As a result, engine 100 moves obliquely left rearward from the initial position (two-dot chain line in FIG. 6) and approaches left suspension tower 14A. When the engine 100 interferes with the support member 60, the support member 60 and the cementer 50 stored in the support member 60 are pushed to the left suspension tower 14A side as shown by arrows in FIG. As a result, the support member 60 is pressed against the left suspension tower 14A. In the present embodiment, the strength of the support member 60 is higher than the strength of the left suspension tower 14A. Therefore, when the support member 60 is pressed against the left suspension tower 14A, the left suspension tower 14A, in particular, the mounting plate 30, the lateral wall 18 and the like are positively deformed to receive an impact caused by a vehicle collision. Therefore, the shape of the support member 60 is easily maintained, and deformation of the cementer 50 stored in the support member 60 is suppressed.

  Further, as shown in FIG. 7, when the vehicle collides with the obstacle 200 from the left front side, the obstacle 200 interferes with the left front portion of the engine 100. As a result, engine 100 moves diagonally right rearward from the initial position (two-dot chain line in FIG. 7) and approaches right suspension tower 14B. In this case, engine 100 does not interfere with support member 60. In the engine room, another member different from the engine 100 such as the actuator 120 of the brake device is disposed in front of the left suspension tower 14A. Such other members may be pushed backward by the obstacle 200 at the time of a vehicle collision and interfere with the support member 60. For example, when the actuator 120 interferes with the support member 60, a load that pushes the support member 60 to the rear of the vehicle acts as shown by an arrow in FIG. In the present embodiment, the support member 60 and the mounting plate 30 are bolted at one point, and the locking portion 40 provided on the support member 60 and the locking piece 41 provided on the mounting plate 30 are locked. By doing so, the support member 60 is connected to the left suspension tower 14A. Since the strength of the locking part 40 is higher than the strength of the locking piece 41, when a load due to a collision acts on the support member 60 in the rear of the vehicle, the locking piece 41 is deformed by the load, and the locking part 40 and the engagement piece 41 are disengaged. In this state, the support member 60 is supported by the mounting plate 30 only by the bolts 80. Therefore, the support member 60 is in a state in which it can rotate relative to the mounting plate 30 with the bolt 80 as a rotation center. As shown in FIG. 8, when the actuator 120 or the like interferes, the support member 60 rotates rearward so as not to be crushed, so that deformation of the support member 60 is suppressed. Therefore, according to the attachment structure of the cementer 50 of this embodiment, the protection function of the cementer 50 at the time of a vehicle collision can be improved.

  (2) The support member 60 is connected to the front side of the vehicle on the side wall in the vehicle width direction of the left suspension tower 14A. Therefore, the cementer 50 stored in the support member 60 is disposed on the front side of the vehicle with respect to the cowl grill 20. The cementer 50 has a pump portion 52 that can be operated from above. However, since the pump portion 52 is not covered by the cowl grill 20, the operator can easily operate. Accordingly, an appropriate arrangement of the cementer 50 having the pump unit 52 can be realized.

  (3) The support member 60 and the mounting plate 30 are bolted together while the locking piece 41 and the locking portion 40 are locked. Thus, during normal operation, the support member 60 is supported at a plurality of locations, and the rotation of the support member 60 due to road surface vibrations of the vehicle is suppressed. Therefore, the retaining property of the cementer 50 by the support member 60 can be improved.

The above embodiment can be implemented with the following modifications.
The shape of the support member 60 can be changed as appropriate. For example, the support member 60 may have a cylindrical shape having substantially the same inner diameter from the upper end to the lower end. In this case, it is desirable that a holding plate is provided in the interior so that the cementer 50 can be stored therein. Further, the support member 60 may be formed in a bottomed box shape. In this case, it is desirable to form a bottom hole capable of operating the drain plug 53 of the segmenter 50 at the bottom of the support member 60. In short, the shape of the support member 60 may be any shape as long as it can store the segmenter 50 and has a peripheral wall surrounding the side surface of the segmenter 50 over the entire circumference.

  The first protrusion 21 and the second protrusion 22 are not necessarily provided on the horizontal wall 18 of the left suspension tower 14A. That is, the projecting pins 23 and 24 may be provided directly on the lateral wall 18 without using the first projecting table 21 and the second projecting table 22.

  In the above embodiment, the example in which the lateral wall 18 and the mounting plate 30 of the left suspension tower 14A are fixed to each other by bolt fastening has been described, but these fixing methods are not limited to those described above. For example, other methods such as welding or adhesion may be employed.

Although the left suspension tower 14A includes the horizontal wall 18 and the mounting plate 30 as separate members, these may be provided as an integrated object.
The locking piece 41 may be configured as a separate member from the mounting plate 30. In this case, the locking piece 41 may be made of a steel material having the same strength as that of the steel material constituting the mounting plate 30, or made of a steel material having a strength different from the strength of the steel material constituting the mounting plate 30. May be. In short, the strength of the locking portion 40 may be higher than the strength of the locking piece 41.

  The support member 60 may be directly connected to the lateral wall 18 of the left suspension tower 14 </ b> A without the attachment plate 30. In this case, the mounting plate 30, the first protruding base 21, and the second protruding base 22 can be omitted. The locking piece 41 may be provided on the lateral wall 18.

  -Although the latching | locking part 40 was each provided in the both ends of the width direction in the back wall 61 of the support member 60, you may abbreviate | omit one. When the locking part 40 is omitted, the locking piece 41 corresponding to the omitted locking part 40 can also be omitted. Further, the locking portion 40 is not limited to both end portions of the back wall 61 in the width direction, and may be provided at the center portion in the width direction or may be provided on the curved wall 62.

  The locking portion 40 may be configured as a separate member from the support member 60. In this case, the locking portion 40 may be made of a steel material having the same strength as that of the steel material constituting the support member 60, or may be made of a steel material having a strength different from the strength of the steel material constituting the support member 60. May be. In short, the strength of the locking portion 40 may be higher than the strength of the locking piece 41.

-The number of the latching | locking parts 40 and the latching pieces 41 can be changed suitably.
A locking piece may be provided on the support member, and a locking portion for locking the locking piece may be provided on the suspension tower. In this case, for example, the configuration shown in FIG. 9 can be employed. As shown in FIG. 9, a support hole 92 and an opening 93 formed below the support hole 92 are formed in the lateral wall 91 of the suspension tower 90. An embedded wall 94 is fixed to the opening 93 by welding, for example. The buried wall 94 has a rectangular opening 95 and is made of a steel material having higher strength than the steel material constituting the suspension tower 90. The support member 96 is formed in a bottomed box shape that can store the cementer 50. The support member 96 is made of a steel material having higher strength than the embedded wall 94. A through hole 98 is formed in the peripheral wall 97 of the support member 96. A locking piece 99 is provided below the through hole 98 in the peripheral wall 97. The locking piece 99 protrudes outward from the peripheral wall 97, and the tip is bent. The locking piece 99 is made of a steel material that is lower in strength than the steel material constituting the embedded wall 94 and higher in strength than the steel material constituting the suspension tower 90. That is, the strength increases in the order of the suspension tower 90, the locking piece 99, the embedded wall 94, and the support member 96. The supporting member 96 is connected to the suspension tower 90 by inserting the engaging piece 99 into the opening 95 and engaging with the embedded wall 94 and fastening with bolts through the through hole 98 and the supporting hole 92. In this attachment structure of the cementer 50, the embedded wall 94 corresponds to a locking portion where the locking piece 99 is locked. Therefore, this structure realizes the attachment structure of the cementer 50 in which the strength of the support member 96 is higher than the strength of the suspension tower 90 and the strength of the embedded wall 94 as the locking portion is higher than the strength of the locking piece 99. You can also. In the above attachment structure of the cementer, the locking piece 99, the suspension tower 90, the embedded wall 94 (locking portion), and the support member 96 are arranged in this order, and the locking piece 99, the embedded wall 94 (locking portion), The constituent material of each member may be set so that the strength increases in the order of the suspension tower 90 and the support member 96. In short, it is sufficient that the strength of the support member is higher than the strength of the suspension tower and the strength of the locking portion is higher than the strength of the locking piece.

  The supporting members 60 and 96 may be connected to the rear side of the vehicle on the inner side walls in the vehicle width direction of the suspension towers 14 and 90 so that the cementer 50 is positioned below the cowl grill 20.

  The suspension towers 14 and 90 and the support members 60 and 96 are made of steel, but may be made of another material such as another alloy or resin. Even in this case, the strength of the support members 60 and 96 may be higher than the strength of the suspension towers 14 and 90, and the strength of the locking portions may be higher than the strength of the locking pieces.
