BATTERY SUPPORT STRUCTURE

Abstract

A battery support structure that supports the battery on a vehicle when it is being pulled in one direction along a horizontal plane. The battery support structure comprises: a first elastic body with a first elastic surface inclined to one side in a direction orthogonal to that direction and along the horizontal plane, which, when the battery is pulled, is enclosed between the battery side and the vehicle side and generates a restoring force against compressive deformation; and a second elastic body with a second elastic surface inclined to the opposite side relative to the first side, which, when the battery is pulled, is enclosed between the battery side and the vehicle side and generates a restoring force against compressive deformation.

Description

Technical area

[0001] The present disclosure relates to a support structure for a battery (here also referred to simply as the "battery support structure"). State of the art

[0002] Vehicles such as electric vehicles and plug-in hybrid vehicles are equipped with an electric motor as their drive source and a battery as their power source to drive the electric motor. A battery mounted in such a vehicle is heavy and therefore requires considerable force to support it. For this reason, the battery is supported by a vehicle body or frame that exhibits high strength.

[0003] For example, PTL 1 describes a support structure for a battery, which is supported by a base plate forming a body. The battery is attached to a battery frame, and the battery frame is supported by the base plate via an anti-vibration rubber that has such hardness that the rubber is deformed by the load of the battery.

[0004] PTL 1 Japanese patent application Publication number 2005-190957 Summary of the invention: Technical problem

[0005] The anti-vibration rubber is positioned at a location that deforms under the battery's load, namely below the battery (on a line perpendicular to the battery). If the anti-vibration rubber were positioned on a horizontal line relative to the battery, it would not deform under the battery's load, and therefore no anti-vibration effect could be expected.

[0006] On the other hand, the vehicle vibrations transmitted to a battery are not limited to vibrations that are perpendicular to the battery, and therefore the battery support structure described in PTL 1 cannot effectively suppress battery rattling caused by vehicle vibrations.

[0007] The aim of the present disclosure is to provide a battery support structure that can effectively suppress battery rattling caused by vehicle vibrations. Solution to the problem

[0008] To achieve the above objective, the battery support structure in the present disclosure is a battery support structure by which the battery is carried on a vehicle in a state in which the battery is pulled in one direction along a horizontal plane, and the battery support structure comprises: a first elastic body with a first elastic surface inclined to one side in a direction along the horizontal plane, and this direction being perpendicular to the aforementioned direction, wherein, when the battery is pulled, the first elastic surface is clamped between one side of the battery and one side of the vehicle and generates a restoring force against compressive deformation of the first elastic surface; and a second elastic body with a second elastic surface inclined towards another side opposite one side, wherein when the battery is pulled the second elastic surface is wedged between the side of the battery and the side of the vehicle and generates a restoring force against the compression deformation of the second elastic surface. Advantageous effects of the invention

[0009] According to the present disclosure, the rattling of a battery caused by vehicle vibrations can be effectively reduced.

(Framework structure)

[0012] As in the Fig. As shown, the frame structure comprises a pair of frames 2 (side elements), cross members 3a, 3b, 3c, 3d, and 3e, brackets 4, brackets 5a, brackets 5b, brackets 6, and locking frames 7. The brackets 4 are each positioned in the same location in the longitudinal direction (Y-direction) of the vehicle within both frames 2. In other words, the brackets 4 are positioned symmetrically to each other along the transverse axis (X-direction) of the vehicle within the frame pair 2. Similarly, the brackets 5a, 5b, 6, and the locking frames 7 are also positioned symmetrically to each other along the transverse axis (X-direction) of the vehicle within the frame pair 2.

[0013] The bracket 4 is a flat, plate-shaped bracket with a substantially rectangular outer shape. The bracket 4 is positioned so that its flat plate surface faces the vehicle's transverse axis (X-direction). The bracket 4 is used to secure the frame 2 and the locking frame 7.

[0014] Bracket 5a is a flat, plate-shaped bracket with a substantially rectangular outer shape. Bracket 5a is positioned so that its flat surface faces the vehicle's transverse axis (X-direction). An upper part of bracket 5a is attached to the groove wall 2a (see Fig. ) with a substantially U-shaped cross-section in the frame 2. The lower part of the bracket 5a is attached to the crossbeam 3a and to the mounting table 8 (see Fig. ) attached. Mounting table 8 is a table for mounting the BTR battery (see Fig. This means that the cross member 3a and the bracket 5a are arranged at a predetermined position along the longitudinal axis of the vehicle where the battery BTR is located. As shown in Fig. As shown, two BTR batteries are attached to vehicle 1. One of the BTR batteries is attached to one of the two frames from the outside, in the direction of the vehicle's transverse axis. The other BTR battery is attached to the other frame of the pair, also from the outside, in the direction of the vehicle's transverse axis.

[0015] Bracket 5b is located at the front of the vehicle (in the -Y direction) compared to bracket 5a. Bracket 5b is a flat, plate-shaped bracket with a substantially rectangular outer shape, similar to bracket 5a. Bracket 5b is positioned in the same way as bracket 5a, with the flat plate surface facing the transverse axis of the vehicle (X direction). An upper part of bracket 5b is attached to the groove wall 2a of frame 2 (see Fig. ). The lower part of the bracket 5b is attached to the crossbeam 3b and the mounting table 8 (see Fig. ). That is, the cross member 3b and the bracket 5b are arranged at a predetermined position along the longitudinal axis of the vehicle in the same way as the cross member 3a and the bracket 5a where the battery BTR is located.

[0016] The bracket 6 (see Fig. ) is a flat, plate-shaped bracket with a predefined outer shape. The bracket 6 is arranged such that its flat plate surface points in the vertical axis (Z-direction). An end section of the bracket 6 on the outside in the direction of the vehicle's transverse axis (+X-direction) is attached to the groove wall 2b of the frame 2 (see Fig. An end section of the bracket 6 on the inside, along the vehicle's transverse axis (-X direction), is attached to the crossmember 3d. The position in the vehicle's longitudinal direction where the bracket 6 is located is an intermediate position between the position along the vehicle's longitudinal axis where the bracket 5a is located and the position along the vehicle's longitudinal axis where the bracket 5b is located. That is, similar to the crossmember 3a, the bracket 5a, the crossmember 3b, and the bracket 5b, the bracket 6 and the crossmember 3d are located at a predetermined position along the vehicle's longitudinal axis where the battery BTR is located.

[0017] The two frames 2 each extend along the longitudinal axis of the vehicle and are arranged so that they are separated from each other along the transverse axis of the vehicle. Frame 2 is formed in a groove shape with a U-shaped cross-section, the opening of the frame facing the inside of the vehicle's transverse axis (-X direction), and comprises a groove wall 2a extending along the vertical axis (Z direction), a groove wall 2b that is bent at the upper end of groove wall 2a and extends in the -X direction, and a groove wall 2c that is bent at the lower end of groove wall 2a and extends in the -X direction. That is, the pair of frames 2 is arranged such that the openings with a groove shape in the direction of the vehicle's transverse axis (X direction) are opposite each other.

[0018] Crossbeams 3a, 3b, 3c, 3d, and 3e are arranged at a predetermined distance from each other and mounted between the frame pair 2. Crossbeams 3a, 3b, 3c, 3d, and 3e are collectively referred to as crossbeam 3 (see Fig. ).

[0019] The frame structure in the present embodiment further comprises a locking frame 7. The locking frame 7 is provided in the opening of the frame 2 and forms a closed cross-sectional shape formed by the frame 2 and the locking frame 7. This makes it possible to reinforce the frame structure. In the following description, a closed cross-sectional shape formed by the frame 2 and the locking frame 7 is referred to as a "closed cross-sectional shape".

[0020] The frame structure in the present embodiment is subject to various limitations to provide satisfactory space for the battery BTR, the motor MTR, and the like, which are to be arranged in the frame 2. For example, the rear end section of the locking frame 7 is shortened. Such a configuration reduces the strength of the frame structure. Therefore, in the Fig. In the embodiment shown in the present application, the rear end section of the locking frame 7 is attached to the frame 2 by a bracket 4 and a fastening element (screw, nut). Furthermore, the cross member 3e is mounted between the two frames 2 at a point in the frontal direction of the vehicle where the rear end section of the locking frame 7 and the frame 2 are attached. This makes it possible to reinforce the frame structure.

[0021] The crossbeam 3a is shaped to have a U-shaped cross-section with the opening facing upwards (+Z-direction) and comprises a bottom wall 3a_1 extending along the vehicle's transverse axis (X-direction), a side wall 3a_2 which is bent at one end of the bottom wall 3a_1 on the outside of the vehicle's transverse axis and extends upwards, and the other side wall 3a_3 which is bent at the other end of the bottom wall 3a_1 on the outside of the vehicle's transverse axis and extends upwards. The outer surface of one side wall 3a_2, in the direction of the vehicle's transverse axis, is attached to the lower part of the bracket 5a by a fastener (screw, nut). The outer surface of the other side wall 3a_3, in the direction of the vehicle's transverse axis, is attached to the lower part of the bracket 5a by a fastener (screw, nut). This secures the crossbeam 3a between the two frames 2 via the bracket 5a.Crossbeam 3a corresponds to the “first crossbeam” within the meaning of the present application.

[0022] The cross member 3b is arranged at a predetermined distance from the cross member 3a at the front of the vehicle (-Y direction). The cross member 3b is shaped to have the same cross-sectional shape as the cross member 3a and comprises a bottom wall 3b_1 extending in the direction of the vehicle's transverse axis (X direction), a side wall 3b_2 which is bent at one end of the bottom wall 3b_1 on the outside in the direction of the vehicle's transverse axis and extends upwards, and the other side wall 3b_3 which is bent at the other end of the bottom wall 3b_1 on the outside in the direction of the vehicle's transverse axis and extends upwards. The outer surface of one side wall 3b_2 in the direction of the vehicle's transverse axis is attached to the lower part of the bracket 5b by a fastening element (screw, nut). The outer surface of the other side wall 3b_3 in the direction of the vehicle's transverse axis is attached to the lower part of the bracket 5b by a fastening element (screw, nut).This allows the crossbeam 3b to be attached between the two frames 2 via the bracket 5b. The crossbeam 3b corresponds to the "first crossbeam" within the meaning of the present application.

[0023] The crossbeam 3d is positioned upwards (+Z-direction) from a central position between a position along the vehicle's longitudinal axis (Y-direction) where the crossbeam 3a is located and a position along the vehicle's longitudinal axis where the crossbeam 3b is located. The crossbeam 3d is a flat, plate-shaped element with a substantially rectangular outer shape and the vehicle's transverse axis (X-direction) as its longitudinal direction. The outer end section of the crossbeam 3d, along the vehicle's transverse axis, is fastened to the inner end section of the bracket 6, along the vehicle's transverse axis (-X-direction), by a fastening element (screw, nut). The crossbeam 3d corresponds to the "second crossbeam" within the meaning of this application.

[0024] As described above, crossbeam 3a, crossbeam 3b, bracket 5a, and bracket 5b are arranged at predetermined positions along the vehicle's longitudinal axis. Furthermore, bracket 6 and crossbeam 3d are arranged at a predetermined position along the vehicle's longitudinal axis. As a result, two closed cross-sectional shapes are formed at predetermined positions along the vehicle's longitudinal axis. The first closed cross-sectional shape is formed by frame pair 2, crossbeam 3a, crossbeam 3d, bracket 5a, bracket 5b, and bracket 6. The second closed cross-sectional shape is formed by frame pair 2, crossbeam 3b, crossbeam 3d, bracket 5a, bracket 5b, and bracket 6.

[0025] Consequently, at a predetermined position in the vehicle's longitudinal direction where the BTR battery is located, when, for example, a moment load about an axis extending in the vehicle's longitudinal direction (Y-direction) acts on the frame pair 2, a force in the opposite direction to the moment load is generated in the cross member 3a and similar components, which form a closed cross-sectional shape, thereby reducing the deformation of the frame 2. As a result, it is possible to increase the strength of the frame structure at a predetermined position in the vehicle's longitudinal direction. This prevents a decrease in the load-bearing stiffness of the battery.

[0026] The crossbeam 3c (see Fig. The cross member 3c is arranged at a predetermined distance from its predetermined position along the vehicle's longitudinal axis in the direction of the vehicle's front (-Y direction). The cross member 3c has the same cross-sectional shape as the cross member 3a and comprises the bottom wall 3c_1, one side wall 3c_2, and the other side wall 3c_3. Consequently, the cross member 3c is mounted between the frame pair 2.

[0027] The MTR engine (see Fig. The motor MTR is arranged on the crossbeam 3c. It is positioned so that it rests on the bottom wall 3c_1. The crossbeam 3c corresponds to the "third crossbeam" of the present application. (Assembly table 8, sliding mechanism 80, and the like)

[0028] The assembly table 8, the sliding mechanism 80 and the like are described below with reference to the Fig. The assembly table 8 is attached to the frame 2 via the sliding mechanism 80 at a position on the outer side of the vehicle's transverse axis (+X-direction). As described above, two BTR batteries are mounted on the vehicle 1. The assembly table 8, the sliding mechanism 80, and the like are also arranged according to each of the two BTR batteries. The following description mainly refers to the BTR battery, which is mounted on the frame 2, which is in Fig. shown on the lower side from the outer side in the direction of the vehicle transverse axis, is attached, as well as the mounting table 8 and the sliding mechanism 80, which are arranged according to this battery BTR, are described.

[0029] The assembly table 8 has an essentially inverted U-shaped cross-sectional form and comprises a top plate 8a having an essentially rectangular, upward-facing (+Z-direction) surface, a flange 8b bent at the vehicle-side end of the top plate 8a and extending downward (-Z-direction), and a flange 8c bent at the vehicle-side end of the top plate 8a and extending downward (-Z-direction). The battery BTR is arranged on the top plate 8a. The battery BTR comprises a plurality of modules and the like, as well as a box-shaped battery housing BTRC that accommodates the modules and the like. A strike plate (not shown) is located at the bottom of the battery housing BTRC. The WL lock 9 is located in the central region of the top plate 8a.The WL locking mechanism 9 is able to come into contact with the stop to restrict the upward movement (+Z direction) of the battery BTR, which is placed on the upper plate 8a, and is able to release itself from the stop to remove the restriction of movement of the battery BTR in the upward direction (+Z direction).

[0030] The sliding mechanism 80 comprises a guide rail 81a, a guide rail 81b, a slider 82a, and a slider 82b. The guide rail 81a extends in the direction of the vehicle's transverse axis (X-direction). The end section of the guide rail 81a on the inside along the vehicle's transverse axis (-X-direction) comprises a flange that is curved and extends upwards, and the flange is attached to the frame 2 via the bracket 5a. The guide rail 81b is located on the front of the vehicle (-Y-direction) relative to the guide rail 81a and extends in the direction of the vehicle's transverse axis (X-direction). The end section of the guide rail 81b on the inside side along the vehicle's transverse axis (-X-direction) is curved and comprises a flange that extends upwards, and the flange is attached to the frame 2 via the bracket 5b.

[0031] The slide 82a is arranged so that it can be guided along the vehicle's transverse axis (X-direction) by the guide rail 81a. The flange 8b is attached to the slide 82a. The slide 82b is arranged so that it can be guided along the guide rail 81b in the X-direction. The flange 8c is attached to the slide 82b. Consequently, the battery BTR, which is located on the upper plate 8a and whose upward movement (+Z-direction) is restricted by the WL lock 9, is integrated with the slide 82a and the slide 82b and is guided along the vehicle's transverse axis (X-direction) by the guide rail 81a and the guide rail 81b. (Fastening element 10)

[0032] Next, the fastening element 10, the joint mechanism 200 and the like will be described with reference to the Fig. described. Fig. is a top view showing the battery support structure in the embodiment of the present application. Fig. is a top view showing the battery support structure when looking through the frame in the present embodiment. Fig. is a top view showing the battery support structures for a pair of batteries in the present embodiment. Fig. is a top view showing the battery support structures for a pair of batteries when the frames are viewed in the embodiment of the present application.

[0033] The insertion direction (i.e., pulling direction) of the battery BTR in the present application is a direction DR1 along the horizontal plane. The insertion direction of the battery BTR in the present embodiment is described as the vehicle's transverse axis on the inside (-X direction). A direction DR1 is not limited to this and is determined depending on the position of the battery BTR. For example, if the position where the battery BTR is mounted is a vehicle rear frame, one direction DR1 could be a direction from the rear of the vehicle to the front of the vehicle.

[0034] In the present embodiment, the battery BTR is placed on the upper plate 8a, with the side wall of the battery facing the inside of the vehicle's transverse axis (X-direction). The battery BTR is held in a position where it is pulled towards the side of the frame 2. The first firing pin STR1 is arranged on the side wall of the battery BTR (the side wall that is pulled towards the fastening element 10). The first firing pin STR1 comprises the following: a bracket STR1_BKT, which has a U-shaped cross-section and an upper wall, a vertical wall, and a lower wall; and a firing rod STR1_BER, which is rod-shaped and is located between the upper wall and the lower wall. The vertical wall of the bracket STR1_BKT is attached to the side wall of the battery BTR such that the direction in which the firing rod STR1_BER extends is in the vertical axis (Z-direction).Frame 2 has an open through-hole TH1 (see . Fig. ) provided, through which the first firing pin STR1 (the upper wall, the lower wall and the firing rod STR1_BER of the bracket STR1_BKT) extends from the outer side in the direction of the vehicle's transverse axis (+X direction) to the inner side in the direction of the vehicle's transverse axis (-X direction) when the battery BTR is pulled to the side of the frame 2.

[0035] The second firing pin STR2 is located on the side wall of battery BTR at a predetermined distance from the first firing pin STR1 in the vehicle's frontal direction (-Y direction). The second firing pin STR2 comprises the bracket STR2_BKT, which has the same shape as the bracket STR1_BKT, and the firing rod STR2_BER, which has the same shape as the firing rod STR1_BER. The bracket STR2_BKT is attached to the side wall of battery BTR such that the direction in which the firing rod STR2_BER extends is in the up-down direction (Z direction). The frame 2 has an open through-hole TH2 (see Fig. ) provided, through which the second firing pin STR2 (the upper wall, the lower wall and the firing rod STR2_BER of the bracket STR2_BKT) runs along the vehicle transverse axis from the outside (+X direction) to the inside (-X direction) when the battery BTR is pulled to the side of frame 2.

[0036] The battery connector BCN is located centrally between the position of the first firing pin STR1 and the position of the second firing pin STR2 on the side wall of the battery BTR. When the battery BTR is pulled against and held against the frame 2, the battery connector BCN is electrically connected to the vehicle-side connector FCN, which is located on the side of the frame 2. Furthermore, the frame 2 has an open through-hole TH3 (see Fig. ) provided, through which the battery connector BCN runs from the outer side in the direction of the vehicle's transverse axis (+X direction) to the inner side in the direction of the vehicle's transverse axis (-X direction) when the battery BTR is pulled to the side of frame 2.

[0037] The fastening element 10 is located on the side of the frame 2. The fastening element 10 holds the battery BTR in a state where the battery BTR is pulled towards the side of the frame 2, such that when the battery BTR is pulled towards the frame side (inward in the direction of the vehicle's transverse axis, -X direction, a direction DR1) with a predetermined force, the battery BTR receives a reaction force against the predetermined force. The fastening system 10 comprises a first latch 11 and a second latch 12. The first latch 11 is configured to be able to make contact with and release itself from the first firing pin STR1. Specifically, the first latch 11 is configured to be able to make contact with and release itself from the firing rod STR1_BER of the first firing pin STR1. The second latch 12 is configured to be able to make contact with and release itself from the second firing pin STR2.can be released from it. In particular, the second bolt 12 is configured such that it can be brought into contact with, or released from, the firing rod STR2_BER of the second firing pin STR2. In the following description, the first bolt 11, which is in contact with / released from the firing rod STR1_BER, is referred to as the first bolt 11, which is in contact with / released from the first firing pin STR1. Similarly, the second bolt 12, which is in contact with / released from the firing rod STR2_BER, is referred to as the second bolt 12, which is in contact with / released from the second firing pin STR2.

[0038] The first bolt 11 can be rotated between an unlocking position, in which the first bolt 11 is released from the first firing pin STR1, and a locking position, in which the first bolt 11 is in contact with the first firing pin STR1, and can further be rotated between the locking position and a pulling position, in which the battery BTR is pulled over the first firing pin STR1 to the side of the vehicle 1.

[0039] The second bolt 12 rotates between an unlocking position in which the second bolt 12 is released from the second firing pin STR2 and a locking position in which the second bolt 12 is in contact with the second firing pin STR2, and is furthermore rotatable between the locking position and a pulling position in which the battery BTR is pulled over the second firing pin STR2 to the side of the vehicle 1. (Joint mechanism 200)

[0040] Fig. is a top view showing the fastening element and the like in the embodiment of the present application. Fig. is a top view showing the fastening element and the like in the embodiment of the present application when looking through the frame. Fig. Figure 1 is a perspective view showing the fastening element and the like in the embodiment of the present application. The joint mechanism 200 comprises a first joint element 210, a second joint element 220, an intermediate joint element 230, and a fixed joint element 240. The joint mechanism 200 in the present embodiment is a parallel joint mechanism.That is, the distance from one end section 211 of the first joint element 210 in the longitudinal direction of the link (here also referred to as "one end section in the longitudinal direction 211") to the other end section 212 of the first joint element 210 in the longitudinal direction of the link (here also referred to as "other end section in the longitudinal direction 212") is equal to the distance from one end section 221 of the second joint element 220 in the longitudinal direction (here also referred to as "one end section in the longitudinal direction 221") to the other end section 222 of the second joint element 220 in the longitudinal direction (here also referred to as "other end section in the longitudinal direction 222"). Furthermore, the length of the intermediate hinge element 230 is equal to the distance between the position of one end section in the longitudinal direction 211 of the first hinge element 210 and the position of one end section in the longitudinal direction 221 of the second hinge element 220.

[0041] In the present embodiment, the fixed joint element 240 is divided into the fixed joint element 240A and the fixed joint element 240B. The fixed joint element 240A is arranged on the frame 2 such that it corresponds to the first latch 11. Furthermore, the fixed joint element 240B is arranged on the frame 2 such that it corresponds to the second latch 12.

[0042] The first joint element 210 consists of two parts. The two links are connected to each other. The first joint element 210 is rotatably coupled at one end section in the longitudinal direction 211 to the fixed joint element 240A and rotatably coupled at the other end section in the longitudinal direction 212 to the first locking bar 11.

[0043] The second joint element 220 consists of two parts. The two joints are connected to each other. The second joint element 220 is rotatably coupled at one end section in the longitudinal direction 221 to the fixed joint element 240B and rotatably coupled at the other end section in the longitudinal direction 222 to the second locking bar 12.

[0044] The intermediate joint element 230 comprises a joint support 231 and a joint rod 232, and the joint support 231 and the joint rod 232 are coupled to each other in such a way that the length of the joint element is adjustable. The intermediate joint element 230 couples the intermediate element 213 (see Fig. ) in the first joint element 210 (the intermediate section located between one end section in the longitudinal direction 211 and the other end section in the longitudinal direction 212) with the intermediate element 213 in the second joint element 220 (the intermediate section located between one end section in the longitudinal direction 221 and the other end section in the longitudinal direction 222). The coupling position of the intermediate joint element 230 is not limited thereto, and, for example, the intermediate joint element 230 can couple the other end section in the longitudinal direction 212 of the first joint element 210 with the other end section in the longitudinal direction 222 of the second joint element 220.

[0045] Next, the functions of the first bolt 11, the second bolt 12, and the joint mechanism 200 will be described with reference to the Fig. described. In the following description, the first bolt 11 and the second bolt 12 are collectively referred to as "locks". Furthermore, the first hinge element 210 and the second hinge element 220 are collectively referred to as "hinge elements". (Actuator 30)

[0046] In the present embodiment, the battery carrier structure 100 comprises a single actuator 30 which actuates both the first latch 11 and the second latch 12 via the joint mechanism 200. The actuator 30 comprises an output rod 31 (see Fig. The actuator 30 is a hydraulic cylinder in the present embodiment. In this embodiment, part of the hydraulic circuit for driving the actuator 30 is omitted. A joint (not shown), which moves in conjunction with the output rod 31, is rotatably arranged in the fixed joint element 240, and the locking pin PIN is attached to the joint. The movement of the locking pin PIN is restricted / released by the shape of the stop, thereby limiting the stroke of the output rod 31.

[0047] The output rod 31 is connected to the first joint element 210. The output rod 31 can be coupled to the second joint element 220. The output rod 31 is movable forwards and backwards along the direction in which the intermediate joint element 230 extends. Furthermore, the output rod 31 is movable backwards and forwards in a direction orthogonal to the pulling direction in which the battery BTR is pulled to the vehicle 1.

[0048] Fig. illustrates the relationship between the position of the bolt and the position of the locking pin. In Fig. The locking pin (PIN) is represented by a single-point catenary line, and the shape of the stop for limiting / releasing the movement of the locking pin (PIN) is represented by a solid line. Fig. The pull direction of the battery BTR is shown counterclockwise, and the retraction direction of the battery BTR is shown clockwise. At the full unlock stroke, i.e., a position in which the latch is rotated a predetermined angle clockwise from the unlock limit, the locking pin PIN abuts the stopper form. As a result, the stroke of the output rod 31 is limited. The starting position for pulling is set to a position in which the latch is rotated a predetermined angle counterclockwise from the unlock limit. The maximum pull position is set to a position in which the latch rotates a predetermined angle counterclockwise from the pull starting position. The locking limit is set to a position in which the latch is movable a predetermined angle counterclockwise from the maximum pull position. At the full locking stroke, i.e.,In a position where the bolt is rotated counterclockwise from the locking limit by a predetermined angle, the locking pin PIN abuts the stopper form. As a result, the stroke of the output rod 31 is limited.

[0049] Fig. This illustrates the relationship between the position of the output rod and the position of the joint. As described above, the joint mechanism 200 in the present embodiment is a parallel joint mechanism, and the first joint element 210 and the second joint element 220 perform the same movement as each other. Fig. The first joint element 210 is shown as a representative joint of the joint mechanism 200 in solid lines, and one end section in the longitudinal direction 211 and the other end section in the longitudinal direction 212 of the first joint element 210 are shown as solid black circles. Fig. is an arc which is a trajectory of a position of the other end section in the longitudinal direction 212 of the first hinge element 210, represented by a one-point catenary, a tangent at each position of the other end section in the arc is represented by a dashed line, and an angle θ of the first hinge element 210 in the longitudinal direction with respect to the direction of the tangent at each position of the other end section is shown.

[0050] When the first bolt 11 rotates between the unlocked and locked positions, the longitudinal direction of the first hinge element 210 forms an acute angle with the direction of a tangent passing through a position of the other end section in the longitudinal direction 212 of the first hinge element 210 (the position on a circumference concentric with the center of rotation of the first bolt 11). That is, in a region between the unlocked and locked positions, the angle θ of the first hinge element 210 in the longitudinal direction changes with respect to the direction of the tangent within a region of an acute angle (0° < θ < 90°).As a result, the first joint element 210 can reliably transmit the force from the actuator 30 to the first bolt 11 in the direction required for the rotation of the first bolt 11 between the unlocking position and the locking position, and can enable smooth rotation of the first bolt, thereby preventing, for example, the occurrence of a blockage.

[0051] When the second bolt 12 rotates between the unlocked and locked positions, the longitudinal direction of the second joint element 220 forms an acute angle with the direction of a tangent passing through a position of the other end section in the longitudinal direction 222 of the second joint element 220 (the position on a circumference concentric with the center of rotation of the second bolt 12). That is, in the same way as with the first bolt 11, the angle θ of the first joint element 210 in the longitudinal direction changes with respect to the direction of the tangent within the region of an acute angle (0° < θ < 90°) between the unlocked and locked positions. Consequently, the second joint element 220 can transmit the force from the actuator 30 to the second bolt 12 in the direction required to rotate it between the unlocked and locked positions.Therefore, the second bar 12 can rotate smoothly in the same way as the first bar 11.

[0052] When the first bolt 11 rotates into the pull position (which is in Fig. (maximum pull position shown), the longitudinal direction of the first joint element 210 is essentially parallel to the direction of a tangent that passes through the position of the other end section in the longitudinal direction 212 of the first joint element 210 on the circumference. Fig. The state in which the longitudinal direction of the second hinge element 220 and the direction of the tangent are parallel to each other is characterized by " θ (= 0)". When the second latch 12 is rotated into the pull position (a position that the in Fig. (corresponding to the maximum pull position shown), the longitudinal direction of the second joint element 220 is essentially parallel to the direction of a tangent passing through the position of the other end section in the longitudinal direction 222 of the second joint element 220 on the circumference. The permissible tolerance of the parallelism in the longitudinal direction with respect to the direction of the tangent is set, for example, according to the driving force of the actuator 30, the set axial force of a bolt that fixes each of the first latches 11, the second latches 12 and the actuator 30, and the like.

[0053] As a result, the first joint element 210 can efficiently transmit the force to rotate the first latch 11 to the first latch 11, and the second joint element 220 can efficiently transmit the force to rotate the second latch 12 to the second latch 12, making it possible to efficiently actuate both the first latch 11 and the second latch 12 and to pull the battery BTR to the side of the vehicle 1 with sufficient force.

[0054] With the configuration described above, the battery BTR is held on the side of frame 2 in a position where it is pulled in a direction DR1 (transverse direction of the vehicle on the inside) along the horizontal plane. As a result, even if vehicle vibrations cause movement of the battery housing BTRC relative to frame 2, frictional resistance is generated between the battery housing BTRC and frame 2, thus suppressing rattling of the battery BTR in both the forward and reverse directions of the vehicle. It should be noted, however, that preventing rattling of the battery BTR along the longitudinal axis of the vehicle may be difficult solely through frictional resistance between the battery housing BTRC and frame 2. (Elastic body 300, first elastic body 300A, second elastic body 300B, elastic body set 300S)

[0055] In the following, the elastic body 300 and the like will be discussed with reference to the Fig. described. Fig. is a top view showing the battery support structure in one embodiment of the present application. Fig. is a top view showing an elastic element and the like in the present embodiment. Fig. Figure 1 is a side view showing the battery carrier structure in the embodiment of the present application. Fig. is a top view showing the battery support structure when looking through the frame in the present embodiment. Fig. is a front view of the battery support structure in the embodiment of the present application, as seen from the front of the vehicle.

[0056] The elastic body 300 is a plate-shaped elastic body with a plate surface area 310 (see Fig. ), which consists of a flat, plate-shaped surface. The elastic body 300 is arranged at a position corresponding to the support 5a and the support 5b, respectively. The elastic body 300 arranged at support 5a is described below as representative, and the elastic body 300 arranged at support 5b is described mainly with regard to its differences from the elastic body 300 arranged at support 5a. Furthermore, the elastic body 300 arranged at the first support 351 is referred to as the first elastic body 300A. Alternatively, the elastic body 300 arranged at the second support 352 is referred to as the second elastic body 300B. The first support 351 and the second support 352 are metal plates. Each of the two end sections of the plate is welded to the support 5a.In the present embodiment, the first elastic body 300A and the second elastic body 300B are used in combination. Hereinafter, a combination of the first elastic body 300A and the second elastic body 300B is referred to as an "elastic body set". Two elastic body sets 300S are arranged on the support 5a such that they are separated from each other in the vertical direction.

[0057] The first elastic body 300A is arranged such that the plate surface 310 becomes the first elastic surface 311 (see Fig. ), which extend to one side in the orthogonal direction (in the present embodiment, the rear of the vehicle) along the horizontal plane with respect to the other direction DR2 (the outer side in the transverse direction of the vehicle). Fig. The first elastic surface 311 is inclined in one direction opposite to DR1 (the inner side in the transverse direction of the vehicle in the present embodiment). Furthermore, the angle of inclination at which the first elastic surface 311 is inclined to one side in the orthogonal direction with respect to the other direction DR2 is adjusted according to the weight, size, and other characteristics of the BTR battery. The first elastic body 300A is arranged on the side of the frame 2 via the first support 351 and the support 5a such that the plate surface 310 forms the first elastic surface 311. The support 5a is shaped such that its horizontal cross-section has the form of a hat channel.The end section of the bracket on the rear of the vehicle (+Y direction) and an end section of the bracket on the front of the vehicle (-Y direction) are located on the inside of the vehicle's transverse axis (-X direction) compared to the middle section of the bracket in the vehicle's longitudinal axis (Y direction). In particular, the plate surface 310 forms the first elastic surface 311 by extending between the end section on the rear of the vehicle and the middle section in the vehicle's longitudinal direction.

[0058] When the battery BTR is pulled in a direction DR1, the first elastic surface 311 is clamped between the side of the battery housing BTRC and the side of the frame 2 (side of the first support 351), and thus compressed and deformed, generating a restoring force against the compressed deformation. As a result, a component in the direction in which the first elastic surface 311 is restored becomes oriented towards another direction DR2 (in the present embodiment, the outer side in the direction of the vehicle's transverse axis). Furthermore, another component in the direction in which the first elastic surface 311 is restored becomes oriented towards a side orthogonal to the other direction DR2 (in the present embodiment, the rear of the vehicle). On the other hand, the battery housing BTRC comprises an inclined surface that is inclined along the first elastic surface 311.As a result, the battery housing BTRC is pushed back in the other direction DR2 and is also pushed back towards the rear of the vehicle by the restoring force of the first elastic surface 311.

[0059] The second elastic surface 312 is located on the front of the vehicle (in the -Y direction) compared to the first elastic surface 311. In other words, the first elastic surface 311 and the second elastic surface 312 are arranged such that they are separated from each other along the longitudinal axis of the vehicle (in the Y direction).

[0060] The second elastic body 300B is arranged such that the plate surface 310 becomes the second elastic surface 312, which is inclined to the other side in the orthogonal direction (vehicle front in the present embodiment) along the horizontal plane with respect to one direction DR1 and the other direction DR2 (vehicle transverse axis, outside). Furthermore, the angle of inclination at which the second elastic surface 312 is inclined to the other side in the orthogonal direction with respect to the other direction DR2 is adjusted according to the weight, size, and other characteristics of the BTR battery. The second elastic body 300B is arranged on the side of the frame 2 via the second support 352 and the support 5a such that the plate surface 310 forms the second elastic surface 312 (see Fig.In particular, the plate surface 310 forms the second elastic surface 312 by extending between the end section of the bracket 5 at the front of the vehicle and the middle section along the longitudinal axis of the vehicle.

[0061] When the battery BTR is pulled in one direction DR1, the second elastic surface 312 is clamped between the side of the battery housing BTRC and the side of the frame 2 (the side of the second support 352), thus being compressed and deformed, and a restoring force against the compression deformation is generated. As a result, a component in the direction in which the second elastic surface 312 is restored is oriented towards the other direction DR2 (outer transverse direction of the vehicle). Furthermore, another component in the direction in which the second elastic surface 312 is restored is oriented towards one side in the orthogonal direction (front of the vehicle) along the horizontal plane with respect to the other direction DR2. On the other hand, the battery housing BTRC includes an inclined surface that is inclined along the second elastic surface 312.As a result, the battery housing BTRC is pushed back in the other direction DR2 and, due to the restoring force of the second elastic surface 312, is also pushed back towards the front of the vehicle. The force with which the battery housing BTRC is pushed back towards the rear of the vehicle by the restoring force of the first elastic surface 311 is balanced by the force with which the battery housing BTRC is pushed back towards the front of the vehicle by the restoring force of the second elastic surface 312.

[0062] With the above configuration, in a case where the battery BTR is mounted on the side of frame 2 in a state where the battery BTR is pulled in one direction DR1 (vehicle transverse direction on the inside), it is possible to suppress rattling of the battery BTR in the vehicle transverse direction (X-direction) for the following reasons, even if vehicle vibrations cause the battery housing BTRC to move relative to the frame 2 in the vehicle transverse direction (X-direction): The battery BTR is held in a state where the reaction force in the other direction DR2 due to the restoring force of the first elastic surface 311 and the tensile force in one direction DR1 are balanced, and the battery BTR is held in a state where the reaction force in the other direction DR2 due to the restoring force of the second elastic surface 312 and the tensile force in one direction DR1 are balanced.Furthermore, even if vehicle vibrations cause the battery housing BTRC to move in the longitudinal direction of the vehicle (Y-direction) with respect to the frame 2, it is possible to suppress rattling of the battery BTR in the longitudinal direction of the vehicle (Y-direction), since the battery BTR is held in a state in which it is balanced in the longitudinal direction of the vehicle (Y-direction) by the respective restoring forces of the first elastic surface 311 and the second elastic surface 312.

[0063] The elastic body 300A arranged in the first bracket 351 has already been described. The elastic body 300B arranged in the second bracket 352 is the same as the elastic body 300A. That is, even if vehicle vibrations cause the battery housing BTRC to move in the direction of the vehicle's transverse axis (X-direction) with respect to the frame 2, it is possible to suppress rattling of the battery BTR in the direction of the vehicle's transverse axis (X-direction) for the following reasons: The battery BTR is held in a state in which the reaction force in the other direction DR2 due to the restoring force of the first elastic surface 311 and the tensile force in one direction DR1 are balanced, and the battery BTR is held in a state in which the reaction force in the other direction DR2 due to the restoring force of the second elastic surface 312 and the tensile force in one direction DR1 are balanced.Furthermore, even if vehicle vibrations cause the battery housing BTRC to move in the longitudinal direction of the vehicle (Y-direction) with respect to the frame 2, it is possible to suppress rattling of the battery BTR in the longitudinal direction of the vehicle (Y-direction), since the battery BTR is held in a state in which it is balanced in the longitudinal direction of the vehicle (Y-direction) by the respective restoring forces of the first elastic surface 311 and the second elastic surface 312.

[0064] As described above, the provision of elastic body 300A and elastic body 300B can prevent the battery BTR from rattling in the transverse direction (X-direction) of the vehicle. Furthermore, it is possible to prevent rattling of the battery BTR in the longitudinal direction (Y-direction) of the vehicle. As described above, the battery BTR, which is placed on the upper plate 8a, is prevented from moving upwards (+Z-direction) by the WL latch 9, thus preventing rattling of the battery BTR in the up-down direction (Z-direction).

[0065] Furthermore, an elastic body set 300S, in which an elastic body 300A and an elastic body 300B are combined, is also arranged on the bracket 5b. Two elastic body sets 300S are arranged vertically spaced apart from each other on the bracket 5b. As a result, when the battery BTR is pulled in a direction DR1 (side of frame 2), the battery BTR receives an uneven reaction force to the pulling force in the front and rear directions of the vehicle (Y-direction). Thus, the battery BTR, for example, does not experience a moment load about the front end section of the vehicle or a moment load about the rear end section of the vehicle, thereby ensuring that the battery BTR is stably attached to the side of frame 2. From this point, it is also possible to suppress rattling of the battery BTR due to vehicle vibrations.

[0066] Furthermore, elastic body sets 300S are arranged at both end sections of the side wall of the battery BTR in the longitudinal direction of the vehicle, and the battery connector BCN is located in the central position of the side wall of the battery BTR in the longitudinal direction of the vehicle. This central position of the side wall of the battery BTR in the longitudinal direction of the vehicle effectively prevents rattling of the battery BTR due to vehicle vibrations. Consequently, it is possible to maintain the electrical connection with the vehicle-side connector FCN.

[0067] The battery support structure 100 in the above embodiment is a battery support structure by which the battery BTR is supported on a vehicle 1 in a state in which the battery BTR is pulled in one direction along a horizontal plane. The battery support structure 100 comprises a first elastic surface 311 inclined in the orthogonal direction along the horizontal plane to one side with respect to the opposite direction, and a second elastic surface 312 inclined in the orthogonal direction along the horizontal plane to the opposite side with respect to the opposite direction.When the battery BTR is pulled, the first elastic surface 311 is enclosed between the side of the battery BTR and the side of the vehicle 1 and generates a restoring force against the compression deformation, and when the battery BTR is pulled, the second elastic surface 312 is enclosed between the side of the battery BTR and the side of the vehicle 1 and generates a restoring force against the compression deformation.

[0068] In the configuration described above, the battery housing BTRC is pushed back in the opposite direction DR2 on the first elastic surface 311 and is also pushed back towards the rear of the vehicle by the restoring force of the first elastic surface 311. Simultaneously, the battery housing BTRC is pushed back in the opposite direction DR2 on the second elastic surface 312 and is also pushed back towards the front of the vehicle by the restoring force of the second elastic surface 312. The force pushing the battery housing BTRC back towards the rear of the vehicle and the force pushing the battery housing BTRC back towards the front of the vehicle are balanced.As a result, the battery BTR is held in a state by the respective restoring forces of the first elastic surface 311 and the second elastic surface 312 in which it is balanced in the direction of the front and rear of the vehicle (Y-direction), so that rattling of the battery BTR in the direction of the front and rear of the vehicle (Y-direction) can be prevented.

[0069] In the battery carrier structure 100 of the above embodiment, the first elastic surface 311 and the second elastic surface 312 are arranged such that they are separated from each other in an orthogonal direction. Furthermore, as described above, the force with which the battery housing BTR is pushed back towards the rear of the vehicle (+Y-direction) by the restoring force of the first elastic surface 311 is balanced by the force with which the battery BTR is pushed back towards the front of the vehicle (-Y-direction) by the restoring force of the second elastic surface 312. Consequently, the battery BTR is not subjected to a moment, for example, due to the difference between the restoring force of the first elastic surface 311 and the restoring force of the second elastic surface 312.Furthermore, no moment is applied, for example, because the direction in which the restoring force of the first elastic surface 311 acts and the direction in which the restoring force of the second elastic surface 312 acts are parallel to each other. The battery BTR is held in a balanced state by the first elastic surface 311 and the like, as described above, and therefore the rattling of the battery BTR due to vehicle vibrations can be effectively suppressed.

[0070] The battery support structure 100 in the above embodiment comprises a first elastic body 300A with a plate surface 310 and a second elastic body 300B with a plate surface 310. The first elastic body 300A is arranged on the side of the vehicle 1 via the first bracket 351, such that the plate surface 310 forms the first elastic surface 311, and the second elastic body 300B is arranged on the side of the vehicle 1 via the second bracket 352, such that the plate surface 310 forms the second elastic surface 312. This configuration makes it possible to use the same component for the first elastic body 300A and the second elastic body 300B. It is also possible to use the same component for the first bracket 351 and the second bracket 352.

[0071] The battery support structure 100 in the above embodiment further comprises a fastening system 10 that restrains the battery unit BTR in a state in which the battery BTR is pulled towards the side of the vehicle 1. The fastening system 10 restrains the battery unit BTR in a state in which the battery BTR is pulled towards the side of the vehicle 1 such that, when the battery unit BTR is pulled with a predetermined force, the fastening system 10 receives a reaction force from the battery BTR against the predetermined force. As a result, the battery BTR is restrained in a state in which it is pulled towards the vehicle 1, and therefore the battery BTR does not move relative to the vehicle 1, thus preventing rattling of the battery BTR due to vehicle vibrations.

[0072] Each of the embodiments described above merely shows one example of a specific implementation of the present disclosure, and the technical scope of the present disclosure should not be interpreted as being limited to such examples. That is to say, the present disclosure can be implemented in many different ways without departing from the spirit or essential features of the disclosure. Industrial applicability
