Description

  The present invention relates to a structure for fixing a tank of a reducing agent or the like to a vehicle.

  In general, when a tank of a reducing agent or the like is mounted on a vehicle, a structure that is appropriately fixed so as not to be displaced or dropped is necessary in consideration of vibration of the vehicle and expansion / contraction of the tank.

  5 and 6 show an example of such a vehicle fixing structure. A bracket 2 having a bottom plate portion 2a, a back plate portion 2b, and left and right side plate portions 2c is attached to the outside of the vehicle frame 1, and a tank 3 placed on the bracket 2 is fixed using a band 4. The tank 3 has a groove-shaped upper bead 3a extending in the left-right direction on the front side of the upper surface (here, the side where the supply port 3b is formed is the front side, and the opposite side is the rear side. With this as a reference, a direction perpendicular to the front-rear direction and the horizontal direction is referred to as a left-right direction), and the band body 4a is disposed on the upper bead 3a. A side bead 3c is formed on the side surface of the tank 3 so as to extend obliquely downward from the upper bead 3a, and a connector (J bolt) 5 for connecting the band 4 and the bracket 2 is disposed here. Locking holes 2d are formed in the left and right side plate portions 2c of the bracket 2, and a hook portion 5a at one end of the J bolt 5 is hooked there. The male screw portion 5b at the other end of the J bolt 5 is passed through through holes 4b formed at the left and right ends of the band 4 and fixed by fasteners such as nuts and washers, thereby connecting the band 4 to the bracket 2. Yes.

  In such a vehicle tank fixing structure, it is necessary to prevent displacement of the tank 3 in both the horizontal direction and the vertical direction. Therefore, in order to load the tank 3 in two directions with one band 4, the band 4 or the J bolt 5 is generally hung diagonally with respect to the tank 3. In the example shown in FIG. 5, the locking hole 2d to which the hook portion 5a of the J bolt 5 is hooked is provided in the vicinity of the center of gravity of the tank 3 in the side plate portion 2c, and the upper bead 3a in which the band body 4a is disposed is on the upper front side. It is formed near the supply port 3b. By arranging the band 4 and the J bolt 5 in this way, the tank 3 is loaded in an oblique direction via the band 4, and the tank 3 is pressed against the bracket 2 in two directions, backward and downward.

  Here, from the viewpoint of preventing the occurrence of a moment in the tank 3 due to the load from the band 4 as much as possible, the direction of the load from the band 4 to the tank 3 is preferably the direction toward the center of gravity of the tank 3 as much as possible. For this reason, in the example shown in FIGS. 5 and 6, the locking hole 2 d is set to be positioned near the center of gravity of the tank 3.

  In addition, as a technical document describing such a vehicle tank fixing structure, for example, there is the following Patent Document 1.

JP2013-203329A

  As described above, in the tank for the vehicle, the fixing portion (the locking hole 2d) on the bracket 2 side is arranged near the center of gravity of the tank 3, while the fixing portion on the tank 3 side (the upper bead 3a on which the belt 4 is arranged). Is preferably near the replenishing port 3b on the front side of the upper surface. However, such a fixing structure is difficult unless the tank 3 has a certain size. The tank 3 is generally molded of plastic resin. In order to provide a structure like the upper bead 3a in the resin tank 3, a radius of curvature of a certain degree or more is provided on both sides of the upper bead 3a for the convenience of manufacturing. A step shape having a height is required (shown as a step portion 3d in FIGS. 5 and 6). That is, in order to form the upper bead 3a in the tank 3, a certain wide area is required around the periphery for forming the stepped portion 3d. For example, it is technically adjoining the upper bead 3a in the immediate vicinity of the supply port 3b. It is difficult to. Therefore, when the tank 3 is designed to be small, even if the upper bead 3a is formed as close as possible to the supply port 3b, the upper bead 3a is separated from the supply port 3b by the stepped portion 3d. Therefore, it is difficult to form the upper bead 3a at a position where the tank 3 can be weighted toward the center of gravity and obliquely. Even if the tank 3 has a certain size, for example, as shown in FIG. 5, it may be necessary to arrange the supply port 3b so as to protrude from the tank 3 body in order to form the upper bead 3a. It was a factor that hindered the ease of installation.

  Or of course, it is also possible to employ | adopt the structure which fixes the tank 3 without using connection tools like the J volt | bolt 5. FIG. However, in that case, it is necessary to review the shape of the tank and the fixing structure itself, and there is a risk of an increase in manufacturing cost and a reduction in tank capacity.

  In addition, in the case of the fixed structure as in this example, since a single band 4 is loaded in both the vertical direction and the horizontal direction, a large tightening force is required, and a large band 4 or J bolt 5 must be used. And the life of the band 4 was shortened.

  In addition, in the arrangement in which the band 4 and the J bolt 5 are obliquely hung, the tip of the male screw portion 5b of the J bolt 5 which is a protrusion inevitably faces the front side where the supply port 3b is located. For this reason, depending on the orientation and installation position of the tank 3, it is necessary to take measures against the automobile external protrusion regulation with respect to the J bolt 5, and the position of the upper bead 3 a may be somewhat rearward from the supply port 3 b, There was also a circumstance that a device such as a protector had to be laid out before that.

  As described above, in the vehicle tank fixing structure, there is a demand to load the tank 3 obliquely with respect to the mechanical structure, but there are various cases where the band 4 and the J bolt 5 are obliquely applied to the tank 3. There were problems and technical difficulties.

  In view of such a situation, the present invention is intended to provide a vehicle tank fixing structure capable of appropriately fixing a tank with a simple configuration.

  The present invention is a vehicle tank fixing structure in which a tank is mounted on a bottom plate portion of a bracket attached to a vehicle, and the tank is fixed to the bracket by a band, and the tank is arranged on the upper surface of the tank. A tank and a fitting for connecting both ends of the band to the bracket weight the tank in a direction perpendicular to the bracket, while a tank side fitting portion formed on the bottom surface of the tank and a bottom plate portion of the bracket. The present invention relates to a vehicle tank fixing structure characterized in that the movement of the tank relative to the bracket is restricted by fitting the formed bracket side fitting portion.

  Thus, in this way, the vertical movement of the tank with respect to the bracket of the tank is restricted by the band and the connector, while the tank side fitting portion and the bracket side fitting portion are fitted in the horizontal direction with respect to the tank bracket. Therefore, the tank can be suitably fixed to the bracket without the band or the connector being obliquely hung on the tank.

  In concrete implementation of the vehicle tank fixing structure of the present invention, the bracket includes a bottom plate portion on which the tank is placed, and a side plate portion that rises to the left and right of the bottom plate portion and supports the tank from both the left and right sides. A locking portion for hooking one end of the connection tool on the side plate, and the band is disposed on an upper bead extending in the left-right direction on the upper surface of the tank, and the other connection tool is connected to both ends. A through hole penetrating through the end, and the through hole is located immediately above the locking portion in a state where the tank is placed on the bracket and the band main body of the band is disposed on the upper bead. In this way, the tank can be reliably loaded in the vertical direction by the band or the fastener.

  In the vehicle tank fixing structure of the present invention, the tank-side fitting portion is a fitting convex portion that protrudes downward from the bottom surface of the tank, and the bracket-side fitting portion opens in a bottom plate portion of the bracket. The fitting hole is preferably used, and in this way, the tank can be easily designed and manufactured when the tank is provided with a structure for fitting with the bracket.

  According to the vehicle tank fixing structure of the present invention, the following various excellent effects can be obtained.

  (I) According to the invention described in claim 1 of the present invention, when the tank is fixed to the bracket, it is not necessary to hang a band or a connecting tool obliquely with respect to the tank, and the upper bead of the tank is connected to the front supply port. It can arrange | position and can be spaced apart and can improve the mounting property to the vehicle of a tank.

  (II) According to the invention described in claim 2 of the present invention, the tank is reliably loaded in the vertical direction by the band or the fastener, so that the fixing of the tank can be further ensured.

  (III) According to the invention described in claim 3 of the present invention, the horizontal displacement of the tank relative to the bracket can be limited with a simple configuration.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 to 4 show an example of a vehicle tank fixing structure according to an embodiment of the present invention, or a form of a tank or a bracket used for the structure. In the drawings, the same reference numerals as those in FIGS. These parts represent the same thing.

  In this embodiment, as shown in FIGS. 1 and 2, a bracket 6 is attached to a vehicle (in this case, the vehicle frame 1), a tank 7 is placed on the bracket 6, and the tank 7 is attached to and detached from the bracket 6 by a band 4. 5 and 6 are the same as in the conventional example shown in FIGS. 5 and 6, but the structure of the bracket 6 and the tank 7, the method of hanging the band 4 and the connecting device (J bolt) 5 on the tank 7, The method of weighting the tank 7 with respect to the bracket 6 is different from the bracket 2 and the tank 3 of the conventional example.

  The tank 7 is molded from a plastic resin, and as shown in FIGS. 3A to 3C, the outer shape is formed in a substantially rectangular parallelepiped shape with the short side in the left-right direction. A replenishment port 7a is provided at a corner formed by the front surface and the upper surface, and an upper bead 7b extending in the left-right direction is formed on the upper surface (note that the side where the replenishment port 7a is formed is also the front side) The opposite side is the rear side, and the direction perpendicular to the front-rear direction is referred to as the left-right direction with reference to this side). A side bead 7c is formed on the side surface so as to extend downward from the upper bead 7b. Furthermore, a fitting convex portion 7d as a tank side fitting portion is formed on a part of the bottom surface so as to protrude downward, and is fitted to a fitting hole 6h provided in a bottom plate portion 6a of the bracket 6 described later. It has become. The fitting protrusion 7d can be formed by, for example, penetrating equipment such as a liquid meter, a temperature sensor, and a concentration sensor in a hole opened in the bottom surface of the tank 7 (not shown). To do). Although not shown in the figure, the fitting convex portion 7d may be provided with, for example, a drain plug so that the liquid inside can be discharged therefrom.

  The bracket 6 is formed by bending a metal plate. As shown in FIGS. 4A to 4C, the bracket 6 rises to the left and right of the bottom plate portion 6a on which the tank 7 is placed and the bottom plate portion 6a. Are provided from the left and right sides. The upper edge of the side plate portion 6b is an inclined side that forms a downward slope from the rear to the front. When the tank 7 is placed on the bottom plate portion 6a, the tank 7 is exposed above the side plate portion 6b. It has become.

  The bracket 6 includes a back plate portion (upper back plate portion) 6c that is bent from the rear side of the side plate portion 6b toward the inner side in the left-right direction to form the back surface of the bracket 6, and the rear side of the bottom plate portion 6a. And a back plate portion (lower back plate portion) 6d that is bent downward from the upper surface and is flush with the upper back plate portion 6c. Bolt holes 6f are formed in the upper back plate portion 6c and the lower back plate portion 6d, respectively, and the bracket 6 can be fixed to the vehicle frame 1 by the mounting bolts 8 through the bolt holes 6f ( (See FIG. 1). Further, the upper back plate portion 6c also plays a role of supporting the tank 7 placed on the bracket 6 from the rear side.

  The left and right side plate portions 6b are each provided with a locking portion 6e at a position facing the lower end of the side bead 7c of the tank 7 when the tank 7 is placed on the bottom plate portion 6a. In the case of the present embodiment, the locking portion 6e is configured as a triangular locking hole with rounded corners, and one of the corners faces upward and the hook portion 5a of the J bolt 5 is hooked. Yes. In addition, the structure of the latching | locking part 6e may be other than the latching hole as shown here, and what kind of thing may function as an anchor which latches the connection tool (J bolt) 5 is sufficient. For example, it can also be a hook-shaped protrusion or the like that protrudes outward from the side plate portion 6b in the left-right direction.

  Further, the bottom plate portion 6a has a fitting hole 6h as a bracket-side fitting portion so as to be fitted to a fitting convex portion 7d (see FIG. 3) protruding from the bottom surface of the tank 7 placed on the bottom plate portion 6a. When the tank 7 is held on the bracket 6, the fitting projection 7 d protrudes from the fitting hole 6 h below the bracket 6.

  The shape of the bracket 6 is not limited to the example shown here. Left and right side plates provided with a bottom plate portion 6a having a bracket-side fitting portion 6h to be fitted to the tank-side fitting portion 7d, and a locking portion 6e for supporting the tank 7 from the side and hooking one end of the connector 5. Any shape may be used as long as the portion 6b is provided and can be fixed to the vehicle frame 1 while suitably supporting the tank 7.

  As shown in FIGS. 1 and 2, the band 4 is accommodated in the upper bead 7b, and a tank is formed while forming a surface along the horizontal direction at both longitudinal ends of the band body 4a extending in the left-right direction along the upper bead 7b. 7 is provided with a locking piece 4c protruding outward in the left-right direction. The locking piece 4c is formed with a through hole 4b through which the male screw portion 5b of the J bolt 5 passes.

  The J bolt 5 is hooked at one end of the hook portion 5a into the engaging hole 2d formed in the side plate portion 6b of the bracket 6, and the other end provided with the male screw portion 5b is inserted into the through hole 4b formed in the engaging piece 4c of the band 4. It is penetrated and fastened by a fastener 9 such as a nut or a washer, whereby both ends of the band 4 are connected to the bracket 6 and the tank 7 is detachably fixed to the bracket 6.

  In addition, although the case where J bolt was used as the connection tool 5 which connects the through-hole 4b of the band 4 and the latching | locking part (locking hole) 6e was illustrated here, as a connection tool 5, besides J bolt, various things are used. Things can be adopted. For example, the locking portion 6e may be a hook-shaped protrusion, and the connection tool 5 may be an eyebolt so that the head ring is hooked on the locking portion 6e.

  In addition to the replenishment port 7a, the upper bead 7b, the side bead 7c, and the like, the tank 7 has various structures such as unevenness and holes for securing strength and weight reduction, and mounting of equipment. Although provided, for the convenience of explanation, illustration of portions not directly related to the fixing structure to the bracket 6 is omitted as appropriate. As the tank 7, in addition to a reducing agent such as urea water used in the SCR system, a tank for various purposes such as a fuel auxiliary tank, an oil tank, and a cooling water tank can be assumed.

  Next, the operation of the present embodiment will be described.

  When the tank 7 is fixed to the vehicle, the tank 7 is placed on the bottom plate portion 6a of the bracket 6 with the bracket 6 fixed to the vehicle frame 1 by the mounting bolts 8 as described above. At this time, as shown in FIGS. 1 and 2, the fitting convex portion 7 d protruding from the bottom surface of the tank 7 is fitted into the fitting hole 6 h opened in the bottom plate portion 6 a of the bracket 6. The fitting convex portion 7d is fitted into the fitting hole 6h in a state of protruding downward from the bottom plate portion 6a, thereby restricting horizontal movement of the tank 7 with respect to the bracket 6.

  Next, the band 4 is placed on the upper bead 7 b on the upper surface of the tank 7, and the hook portion 5 a at one end of the J bolt 5 is hooked into the locking hole 6 e opened in the side plate portion 6 b of the bracket 6. The male screw portion 5 b at the end is passed through the through holes 4 b formed in the locking pieces 4 c at both ends in the longitudinal direction of the band 4 and fastened with the fastener 9. The J bolt 5 is connected between the band 4 and the bracket 6 while being accommodated in the side bead 7 c of the tank 7. At this time, the tightening degree of the band 4 with respect to the tank 7 can be adjusted by adjusting the position of the fastener 9 in the male screw portion 5b.

  Here, in this embodiment, unlike the above-described conventional example (see FIGS. 5 and 6), the tank 7 is placed on the bracket 6 and the band body 4a of the band 4 is arranged on the upper bead 7b. The through hole 4b is positioned immediately above the locking hole 6e in a side view. The upper bead 7b and the side bead 7c of the tank 7 are also formed so as to follow this arrangement, and the side bead 7c extends directly from a position facing the locking hole 6e on both side surfaces of the tank 7, The left and right side beads 7c are continuous with the left and right ends of the upper bead 7b. When the band body 4a is placed on the upper bead 7b, the locking piece 4c protrudes from both left and right ends of the upper bead 7b, and a vertical gap is formed between the locking piece 4c and the locking hole 6e immediately below the locking piece 4c. A J bolt 5 arranged in the side bead 7c is connected along the direction. Thus, in this embodiment, the band 4 or the J bolt 5 is not slanted with respect to the tank 7, and the tank 7 is loaded vertically downward with respect to the bracket 6 by the band 4. Yes.

  If such a fixing structure is adopted, the tank 7 is restricted in movement in the vertical direction by the band 4 and the J bolt 5, while the movement in the horizontal direction is between the fitting convex portion 7 d and the fitting hole 6 h. Limited by mating. At this time, since the band 4 and the J bolt 5 need only load the tank 7 in the vertical direction, unlike the above-described conventional example (see FIGS. 5 and 6), it is not necessary to hang the tank 7 diagonally. Accordingly, the upper bead 7b of the tank 7 may be formed at a position directly above the position facing the locking hole 6e of the bracket 6, and can be disposed away from the front supply port 7a. For this reason, in designing the tank 7, it is not necessary to consider the interference between the stepped portion 7f formed around the upper bead 7b and the supply port 7a, and the supply port 7a is projected to the front as in the above-described conventional example. Therefore, it is possible to improve the mountability of the tank 7 on the vehicle.

  Further, as a result of the through-hole 4b of the band 4 being located immediately above the locking hole 6e of the bracket 6, the tip of the male screw portion 5b of the J bolt 5 does not face the front side, and the position of the tip itself is also described above. The arrangement is deeper on the rear side than the conventional example. For this reason, it is possible to clear the external vehicle protrusion regulation without any special device.

  Further, with respect to the band 4 and the J bolt 5, the weight applied to the tank 7 is only in the vertical direction, and there is no need for the weight in the horizontal direction. Therefore, the required tightening force is small compared to the conventional example. For this reason, the band 4 and the J bolt 5 can be reduced in size, the burden on the band 4 can be reduced, and the life of the band 4 can be extended.

  Moreover, regarding the fixing in the horizontal direction, when the tank 7 is placed on the bracket 6, the fitting projection 7 d is merely fitted into the fitting hole 6 h, so that the tank 7 can be compared with the conventional example. It does not take much time to attach and detach. Further, the structure is simple, and there is no particular difficulty in designing the tank 7 and the bracket 6.

  Here, the case where the tank side fitting portion 7d is a fitting convex portion and the bracket side fitting portion 6h is a fitting hole is described as an example. However, the tank side fitting portion 7d and the bracket side fitting portion are described. The structure of 6h is not limited to this, and any structure may be used as long as it is fitted with each other and the horizontal displacement of the tank 7 with respect to the bracket 6 is limited. For example, contrary to the example shown here, the tank-side fitting portion 7d is a recess provided on the bottom surface of the tank 7, and the bracket-side fitting portion 6h protrudes upward from the bottom plate portion of the bracket 6. It is also possible. However, in this case, the capacity of the tank 7 is reduced by the amount of the concave portion, and a step portion (a structure corresponding to the step portion 7f with respect to the upper bead 7b and the side bead 7c) is provided around the concave portion. It becomes necessary and the shape of the tank 7 becomes complicated. For this reason, from the viewpoint of facilitating the design and manufacture of the tank 7, it is more preferable to form the tank side fitting portion 7d as a fitting convex portion as in this embodiment shown in FIGS. I can say that.

  In addition, when the tank-side fitting portion 7d is a fitting convex portion and a drain plug is installed in the fitting convex portion 7d, for example, the liquid is discharged from a position lower than the bottom surface of the tank 7, Efficient discharge becomes possible. Thus, there are various merits in using the tank side fitting portion 7d as the fitting convex portion.

  As described above, in the present embodiment, the tank 7 is mounted on the bottom plate portion 6a of the bracket 6 attached to the vehicle, and the tank 7 is fixed to the bracket 6 by the band 4. Regarding the fixing structure, the tank 7 is weighted in the vertical direction with respect to the bracket 6 by the band 4 arranged on the upper surface of the tank 7 and the connector (J bolt) 5 for connecting both ends of the band 4 to the bracket 6. By fitting a tank side fitting portion (fitting convex portion) 7d formed on the bottom surface with a bracket side fitting portion (fitting hole) 6h formed on the bottom plate portion 6a of the bracket 6, the bracket of the tank 7 is fitted. The movement with respect to 6 is limited. Thus, while the band 4 and the connector (J bolt) 5 restrict the vertical movement of the tank 7 with respect to the bracket 6, the tank side fitting portion (fitting convex portion) 7d and the bracket side fitting portion (fitting hole) ) Since the horizontal movement of the tank 7 with respect to the bracket 6 is restricted by fitting with 6h, the tank 7 is suitably fixed to the bracket 6 even if the band 4 and the connector 5 are not obliquely hung on the tank 7. can do. Therefore, the upper bead 7b of the tank 7 can be disposed away from the supply port 7a on the front surface, and the mountability of the tank b on the vehicle can be improved.

  In this embodiment, the bracket 6 includes a bottom plate portion 6a on which the tank 7 is placed, and a side plate portion 6b that rises to the left and right of the bottom plate portion 6a and supports the tank 7 from both the left and right sides, and the side plate portion 6b. Is provided with a locking portion (locking hole) 6e for hooking one end of the connection tool (J bolt) 5, and the band 4 is disposed on an upper bead 7b extending in the left-right direction on the upper surface of the tank 7, and has both ends Is provided with a through hole 4b penetrating the other end of the connector (J bolt) 5, and the through hole 4b places the tank 7 on the bracket 6 and arranges the band body 4a of the band 4 on the upper bead 7b. In this state, the tank 7 is positioned directly above the locking portion (locking hole) 6e. Therefore, the tank 7 is reliably loaded in the vertical direction by the band 4 and the fastener (J bolt) 5, and the tank 7 To make it more secure That.

  In this embodiment, the tank-side fitting portion 7 d is a fitting convex portion that protrudes downward from the bottom surface of the tank 7, and the bracket-side fitting portion 6 h is a fitting hole that opens to the bottom plate portion of the bracket 6. Therefore, when the tank 7 has a structure for fitting with the bracket 6, the tank 7 can be easily designed and manufactured, and the horizontal displacement of the tank 7 with respect to the bracket 6 can be limited with a simple configuration. .

  Therefore, according to the present embodiment, the tank can be appropriately fixed with a simple configuration.

  It should be noted that the vehicle tank fixing structure of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
