Description

  The present invention relates to a battery support structure in which a battery tray on which a battery is mounted is movably supported on a battery table and the battery tray is fixed at a fixed position.

  Conventionally, in a vehicle such as an automobile, a battery is often provided in an engine room provided in the front part of the vehicle body. The front hood that opens and closes the engine room has many front-opening systems, and the battery is arranged near the side wall of the front part of the engine room, so that the workability at the time of battery attachment / detachment and inspection is improved.

  By the way, the impact energy generated at the time of a frontal collision (hereinafter abbreviated as “front collision”) is absorbed by crushing the front part of the pair of side frames disposed on the left and right sides of the front part of the vehicle body in the vehicle width direction. . However, since the battery is a highly rigid body and is not crushed, the battery only retreats without being destroyed at the time of the front collision, not only the impact energy is not absorbed, but also when it collides with another rigid body when the battery retreats, There is a disadvantage that the crash stroke of the side frame is not secured.

  In addition, the front part of the engine room is gradually narrowed from the viewpoint of design and aerodynamic characteristics, so that a sufficient space between the engine hood and the upper surface of the battery cannot be secured. There is an inconvenience that it becomes impossible to absorb the impact energy to the falling object due to the deformation of the engine hood.

Therefore, in order to efficiently absorb the impact energy at the time of the front collision and the impact energy to the falling object from above, for example, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 8-164760), the battery is used as the engine. It is desirable to arrange in the vicinity between the toe board and the strut housing at the rear of the room.
JP-A-8-164760

  However, when the battery is installed at the rear of the engine room, if the front hood is of the front opening type, the battery will be installed on the hood hinge side. There is a problem that a large opening cannot be obtained and workability is poor.

  In view of the above circumstances, the present invention provides a battery support capable of easily attaching and detaching and inspecting the battery and obtaining good workability even when the battery is disposed, for example, between the toe board and the strut housing. The purpose is to provide a structure.

  To achieve the above object, the present invention provides a battery support structure in which a battery tray is provided at a rear portion in an engine room, and a battery is placed and fixed on the battery tray, and the battery tray is fixed to the engine room.

The battery tray is movably supported between the battery fixing position and the battery attaching / detaching position set to a position moved forward from the battery fixing position. The battery tray when the battery tray is set at the fixed position. Characterized by engaging the engaging portion provided.

  According to the present invention, the battery tray is slidably mounted on the battery table, and the battery tray can be moved in a certain direction by the guide rail and the support portion supported by the guide rail. Even when the fixed battery is disposed, for example, between the toe board and the strut housing, the battery tray can be attached and detached by sliding the battery tray on the battery table to the attachment / detachment position. Inspection becomes easy and good workability can be obtained.

  A battery table 21 is fixed between the strut tower 10 and the toe board 2 disposed on the left side in the vehicle width direction in the engine room E, and the battery 20 is placed and fixed on the battery table 21. A tray 22 is installed. 2 shows a state in which the battery 20 is fixed to the battery tray 22 via a rod or a holding plate, but the structure for fixing the battery 20 to the battery tray 22 is limited to this. It is not a thing. Moreover, the battery table 21 and the battery tray 22 are resin molded products, and reinforcing fibers such as glass fibers and carbon fibers are mixed in order to enhance toughness.

  As shown in FIG. 3, the battery table 21 is fixed between the strut tower 10 and the toe board 2, and its posture is a center line C / L in the vehicle width direction in which the front end side extends in the longitudinal direction of the vehicle body. Is set obliquely forward, and the rear end is directed to the left side of the vehicle body. Further, the toe board 2 is formed with a recess 2 a that avoids interference with the rear end side of the battery table 21.

  As shown in FIGS. 5 to 8, the battery tray 22 is formed in a rectangular box shape on which the battery 20 can be placed. The wall surface of the battery tray 22 is shallow on the front surface 22 a side and deep on the back surface 22 b side. Further, side protrusions 23 and 24 project outward from the bottom surface of both longitudinal side surfaces 22c of the battery tray 22, and the rear protrusion 25 protrudes outward from the substantially central bottom surface of the back surface 22b. Is formed. Both ends of the projecting piece portions 23 to 25 are tapered.

  Moreover, as shown in FIG. 9, the upper surfaces 23a and 24a of the side protrusions 23 and 24 are formed in an inclined shape that expands from the tip toward the base. Although not shown, the upper surface 25a of the rear protruding piece 25 is also formed in a tapered shape that converges outward, like the upper surface 23a (or 24a) of the side protruding piece 23 (or 24).

  Further, first to third support portions 26 a to 26 c are formed to protrude from the bottom surface of the battery tray 22. Each support part 26a-26c is arrange | positioned at each vertex of the triangle in the position biased to the right side 22c.

  On the other hand, as shown in FIGS. 4, 8, and 9, first to third guide rails 27 to 27 that guide the support portions 26 a to 26 c that protrude from the bottom surface of the battery tray 22 on the battery table 21. 29 is formed. The battery tray 22 is made movable along the guide rails 27 to 29 by supporting the support portions 26a to 26c on the guide rails 27 to 29 corresponding thereto. The first and second guide rails 27 and 28 are formed in a groove shape having a predetermined depth, and the third guide rail 29 is formed in a slit shape penetrating the bottom surface. By the way, the height of the support portions 26a and 26b protruding from the bottom surface of the battery tray 22 is formed higher than the groove depth of the first and second guide rails 27 and 28 that support the support portions 26a and 26b. Has been. The lower end of the third support portion 26c supported by the third guide rail 29 is exposed from the bottom surface of the battery table 21, and a retaining flange member 30 is provided at the lower end.

  In FIG. 3, the state which moved the battery tray 22 to the attachment or detachment position is shown with a dashed-dotted line. The battery tray 22 faces the middle of the engine room E, and its front surface 22a is oriented in a direction substantially parallel to the center line C / L in the vehicle width direction, that is, forward. The posture of the battery tray 22 is determined by the relationship between the support portions 26a to 26c projecting from the bottom surface of the battery tray 22 and the guide rails 27 to 29 that support the support portions 26a to 26c. .

  The relationship between the two is shown in FIG. As shown in FIG. 11, in a state where the battery tray 22 is moved to the attachment / detachment position of the battery table 21, the support portions 26 a to 26 c are hooked on the distal ends of the guide rails 27 to 29. Naturally, the tips P1 to P3 of the rails 27 to 29 are formed at substantially the same intervals as the support portions 26a to 26c. Hereinafter, the tracks of the guide rails 27 to 29 will be described with reference to the tips P1 to P3.

  Front straight rail portions 27a and 29a are formed at the tips P1 and P3 of the first and third guide rails 27 and 29, respectively. The front straight rail portions 27a and 29a are extended in parallel by a predetermined length rearward along the center line C / L in the vehicle width direction. Further, a curved rail portion 27 b is formed continuously from the rear end of the front straight rail portion 27 a of the second guide rail 27. The curved rail portion 27b is formed with a radius centered on a bent portion P4 between a front straight rail portion 29a of the third guide rail 29 and a rear straight rail portion 29b described later. Further, a curved rail portion 28 a is formed continuously with the tip P <b> 2 of the second guide rail 28. The curved rail portion 28a is also formed with a radius centered on a bent portion P4 between the front straight rail portion 29a and the rear straight rail portion 29b of the third guide rail 29.

  There is a predetermined backlash between each guide rail 27 to 29 and the support portions 26a to 26c supported by the guide rails 27 to 29. Therefore, even if the tip end portion of the second guide rail 28 is not formed in a straight line shape, the battery tray 22 can be moved by the backlash between the guide rails 27 to 29 and the support portions 26a to 26c. A straight movement is possible along the front straight rail portions 27a and 29a of the rails 27 and 29.

  As shown by the alternate long and short dash line in FIG. 12, the curved rail portions 27b and 28a formed on the first and second guide rails 27 and 28 are provided with a support portion 26c protruding from the bottom surface of the battery tray 22, respectively. 3 When the battery tray 22 is rotated around the rear end of the front straight rail portion 29a of the guide rail 29, the battery tray 22 is allowed to rotate until reaching the position along the longitudinal direction of the battery table 21. It is formed to the length to be.

  The rear straight rail portions 27c, 28b, and 29b are provided at the rear end of the front straight rail portion 29a of the third guide rail 29 and the rear ends of the curved rail portions 27b and 28a of the first and second guide rails 27 and 28, respectively. It is continuous. The rear straight rail portions 27 c, 28 b and 29 b are formed in parallel along the extending direction of the battery table 21. A hole 29c formed in the rear end portion of the third guide rail 29 is inserted through the retaining flange member 30.

  As shown in FIG. 4, when the battery tray 22 is retracted along the rear straight rail portions 27c, 28b, 29b at the rear end portion of the battery table 21, it is formed on the left side surface of the battery tray 22. A pair of side surface locking portions 31 a and 31 b that hook both ends of the side surface protruding piece portion 23 are formed. In addition, a back surface locking portion 32 that hooks the back surface protruding piece portion 25 is formed on the side surface of the battery table 21.

  As shown in FIGS. 4 and 9, the inner surfaces of the side surface locking portions 31 a and 31 b are formed substantially along the shape of both end portions of the side surface protruding piece portion 23, and the back surface locking portion 32 is It is formed in substantially the same shape as one side locking portion 31a. When the battery tray 22 is moved along the rear straight rail portions 27c, 28b, and 29b of the guide rails 27 to 29, both ends of the side protrusion 23 are inserted into the side locking portions 31a and 31b and positioned. In addition, the end of the back protrusion 25 is inserted into the back locking portion 32 and positioned.

  Further, as shown in FIG. 4, the side protruding piece 23 of the battery tray 22 is hooked on the side locking portions 31 a and 31 b, and the back protruding piece 25 is locked on the back locking portion 32. Thus, the right side protruding piece 24 is fixed by the tray fixing plate 33.

  As shown in FIGS. 9 and 10, the tray fixing plate 33 is formed by bending an elastic strip-shaped flat plate along the longitudinal direction, a fixing surface 33a is formed on the proximal end side, and a pressing surface on the distal end side. 33b is formed. Further, a bolt insertion hole 33c is formed in the center of the fixing surface 33a in the width direction. On the other hand, the battery table 21 is insert-molded with a nut 35 into which a fixing bolt 34 inserted into the bolt insertion hole 33c is screwed. When the fixing bolt 34 inserted through the bolt insertion hole 33c is screwed into the nut 35, the pressing surface 33b of the tray fixing plate 33 presses the upper surface 24a of the right side protruding piece 24, and the side protruding piece is self-deformed. 24 is pressed and fixed.

  Next, the effect | action of this form by such a structure is demonstrated. When the battery 20 is placed and fixed on the battery tray 22 on the assembly line, or when the battery 20 that has already been assembled is replaced or the battery 20 is inspected, the battery 20 is first set at the fixed position shown in FIG. The battery tray 22 is pulled out to the attaching / detaching position along the guide rails 27 to 29 formed on the battery table 21.

  Then, as shown in FIG. 11, the support portions 26 a to 26 c protruding from the bottom surface of the battery tray 22 are formed at the tips P 1 to P 1 of the first to third guide rails 27 to 29 formed on the battery table 21. The battery tray 22 that is placed on and fixed to the battery compartment 22 is pulled out to the attachment / detachment position in the engine room E as shown by the one-dot chain line in FIG. 3 and the solid line in FIG. Directed to the front of room E.

  Since the battery tray 22 can be moved from the fixed position of the engine room E to the attachment / detachment position, the attachment / detachment or inspection of the battery 20 does not need to be performed near the hood hinge where the engine hood is not sufficiently opened. Will improve.

  Then, after the battery 20 is placed on the battery tray 22 and fixed in place, when the battery 20 is pressed rearward, as shown by the one-dot chain line in FIG. 26a and 26c move linearly rearward along the front straight rail portions 27a and 29a formed on the first and third guide rails 27 and 29 formed on the battery table 21. In addition, although the front-end | tip part of the 2nd guide rail 28 which guides the support part 26b is not formed in linear form, since there is backlash between each guide rail 27-29 and each support part 26a-26c, a support part 26 b also moves along the second guide rail 28.

  When the support portion 26c reaches the rear end of the front straight rail portion 29a formed on the third guide rail 29, the front straight rail portion 29a of the third guide rail 29 and the rear straight rail continuous therewith. Since the bent portion P4 is formed at the connection portion with the portion 29b, the support portion 26c is temporarily latched by the bent portion P4.

  On the other hand, curved rail portions 27b and 28a continuous to the rear end of the front linear rail portion 27a of the first guide rail 27 that guides the support portion 26a and the front end P2 of the second guide rail 27 that guides the support portion 26b, It is formed with a radius centered on the bent portion P4. Accordingly, when the battery tray 22 is further pressed, as shown by an arrow in FIG. 12, the curved rail portion 27b having the support portion 26c as the center and the other support portions 26a and 26b formed on the guide rails 27 and 28, respectively. , 28a, rotate counterclockwise in the figure.

  In this embodiment, when the battery tray 22 is returned to the fixed position, the battery tray 22 is once retracted linearly without suddenly rotating, so that the operator can move the battery tray 22 in the rotational direction. Therefore, the battery tray 22 can be moved with peace of mind.

  Thereafter, the support portions 26a and 26b protruding from the bottom surface of the battery tray 22 reach the end of the curved rail portions 27b and 28a formed on the first and second guide rails, and the rear straight rail portions 27c and 28b. When the rotation is stopped by the bent portion, the battery tray 22 is parallel to the side surface of the battery table 21 and the right side surface 22c of the battery tray 22 is the battery as shown by the one-dot chain line in FIG. The posture is directed to the front of the table 21.

  When the right side surface 22c of the battery 20 is pressed rearward in this state, the support portions 26a to 26c projecting from the bottom surface of the battery tray 22 are connected to the guide rails 27 to 29 formed on the battery table 21. It moves linearly along the rear straight rail portions 27c, 28b, 29b.

  Then, as shown in FIG. 4, the side protrusions 23 formed on the left side 22 c of the battery tray 22 are engaged with the locking portions 31 a and 31 b formed at the rear of the battery table 21. Is positioned. At the same time, the back protrusion 25 formed on the back surface 22 b is engaged with and positioned in the back surface locking portion 32 formed on the battery table 21.

  By the way, the height of the support portions 26a and 26b projecting from the bottom surface of the battery tray 22 is higher than the groove depth of the first and second guide rails 27 and 28 that support the support portions 26a and 26b. When moving on the battery table 21, the support portions 26a and 26b slide on the bottoms of the first and second guide rails 27 and 28, so that the entire bottom surface of the battery tray 22 does not slide. , Sliding resistance is reduced and can be moved smoothly.

  In this way, the protruding piece 23.25 protruding outward from the battery tray 22 is hooked to the side locking portions 31a and 31b and the back locking portion 32 formed on the battery table 21, When the battery tray 22 is set at a fixed position, the rear portion of the battery 20 is buried below the bulkhead 3 as shown in FIG. Further, the battery tray 22 is formed on the fuel pipe protector 18 disposed on the left side of the engine 12 at the front side of the vehicle body of one ridge portion 20a, with the right side surface 22c being disposed obliquely toward the center in the vehicle width direction. An inclined pressing surface 18a is provided.

  Next, as shown in FIGS. 9 and 10, the pressing surface 33 b of the tray fixing plate 33 is brought into contact with the right side protruding piece 24 of the battery tray 22. Next, the fixing bolt 34 is inserted into a bolt insertion hole 33c drilled in the center of the fixing surface 33a, and is screwed into a nut 35 that is insert-molded into the battery table 21, so that the fixing surface 33a is inserted into the battery table 21. Press to fix. Then, the pressing surface 33b presses the right side protruding piece 24 against the battery table 21, and the battery tray 22 is fixed.

  Thus, in this embodiment, since the battery 20 is disposed in the rear part of the engine room E, for example, the front part of the front hood that collides with a pedestrian and the head of the pedestrian etc. closes the upper part of the engine room E. Alternatively, even if the vehicle is dropped in the middle, a high-rigid body such as the battery 20 is not provided at the dropping position, so that the front hood has a sufficient amount of deformation to absorb impact energy. Can do.

  Even when the battery 20 is fixed at a fixed position in the engine room E, when the battery 20 is replaced or inspected, the battery tray 22 is guided to the battery table 21 and attached or detached. Since it can be pulled out to a position and work can be performed at that position, the number of work steps can be significantly reduced.

  Further, when the battery tray 22 is pulled out to the attachment / detachment position and when the battery tray 22 is pulled back to the fixed position, the battery tray 22 moves on the battery table 21. It can be easily pulled out and stored. In this case, since each support part 26a-26c protrudingly provided by the bottom face of the battery tray 22 is guide | induced along the guide rails 27-29 formed in the battery table 21, it always has a fixed position and an attachment / detachment position. It can be guided unambiguously and has good workability.

  Further, when the battery tray 22 is set at a fixed position, a side protrusion 31a formed on the battery table 21 is a side protrusion piece 23 protruding from the left side 22c on the back side of the battery tray 22. , 31b are automatically hooked and positioned so that the battery tray 22 can be easily attached to the battery table 21 simply by fixing the right side protrusion 24 exposed on the front side of the engine room E with the tray fixing plate 33. The workability is good.

  Further, as shown by a one-dot chain line in FIG. 3, when the battery tray 22 is pulled out to the attachment / detachment position, each support projecting from the bottom surface of the battery tray 22 is provided at the tips P1 to P3 of the guide rails 27 to 29. Since the parts 26a to 26c are hooked and the battery tray 22 is directed to the front of the engine room E, the posture of the battery 20 is always constant, and the work efficiency at the time of attachment / detachment and inspection of the battery 20 is improved. To do.

  By the way, when the vehicle body 1 collides in front, the impact load is absorbed by crushing the tip portions of the pair of left and right side frames 6 via the bumper beam 7. At that time, the power train 11 including the engine 12 slides relatively rearward of the vehicle body 1, thereby ensuring the crash stroke of the side frame 6.

  As shown by the arrows in FIG. 3, when the power train 11 including the engine 12 moves backward, the inclined pressing surface 18 a formed on the fuel pipe protector 18 disposed on the left side of the engine 12 becomes the ridge portion of the battery 20. 20a is touched and this battery 20 is pushed back. Then, the side protrusion 24 on the right side of the battery tray 22 on which the battery 20 is placed and fixed is detached from the tray fixing plate 33, and the side locking that holds the left side protrusion 23 and the back protrusion 25 is further provided. The parts 31a and 31b and the back locking part 32 are destroyed by the impact from the projecting piece parts 23 and 25, and the battery tray 22 is rotated in the clockwise direction in the drawing as shown by the two-dot chain line in FIG. While rotating, it is retracted in the direction of the recess 2 a formed in the toe board 2.

  Thus, the battery 20 is pushed out to the left in the width direction of the vehicle body 1 by the inclined pressing surface 18a of the fuel pipe protector 18 provided in the engine 12 that is moving backward, so that the battery 20 is connected to the engine 12, the toe board 2, and the like. The stroke of the power train 11 in the backward direction can be sufficiently secured. Therefore, the crash stroke of the side frame 6 is not hindered and the impact energy can be absorbed well.

  In addition, this invention is not restricted to the form mentioned above, For example, the guide rails 27-29 may be formed in the bottom face of the battery tray 22, and you may make it form the support parts 26a-26c in the battery table 21. FIG.
