Description

  The present invention relates to a vehicle including an electric drive device such as a battery such as an electric vehicle.

In an electric vehicle, a motor is driven by electric power stored in a battery and travels by the driving force of the motor. The cruising distance is limited by the stored power of the battery. It is desirable to load a large number of large capacity batteries in an electric vehicle.
In an electric vehicle, generally, a large number of batteries are loaded under a floor of a riding space or in a rear luggage compartment. However, when all the batteries are arranged in the boarding space or cargo compartment of the electric vehicle, a trade-off is established between the loading capacity of the boarding space or cargo compartment and the cruising distance. In order to increase the cruising range of an electric vehicle, it is necessary to sacrifice the loading capacity of the riding space and the cargo space.
As described above, a vehicle such as an electric vehicle is required to improve the cruising distance of the vehicle without sacrificing the boarding space or the cargo space. Thus, it is conceivable to arrange an electric drive device such as a battery in the front part of the vehicle, for example, in the engine compartment (Patent Document 1).
As a result, the boarding space and the cargo space are unlikely to be sacrificed.

  However, when an electric drive device such as a battery is arranged in the front part of the vehicle, the collision performance of the vehicle may be affected as compared with the case where the electric drive device is arranged in the boarding space or the luggage compartment. For example, a full-lap collision test and an offset collision test are available as a collision test for vehicles including electric vehicles.

  As described above, in a vehicle such as an electric vehicle, for example, it is required to improve the cruising distance of the vehicle while suppressing the influence on the collision performance of the vehicle or the loading capacity of the boarding space and the luggage compartment.

  A vehicle including an electric drive device according to the present invention is a vehicle including an electric drive device including a battery, and is higher than the pair of lower frames projecting forward from the front partition wall of the boarding space of the vehicle, and the pair of lower frames. A pair of upper frames projecting forward from the front partition, and a vertical wall interconnecting the central portion of the pair of lower frames and the central portion of the pair of upper frames, the vertical wall and the front wall A vertical wall member for accommodating an electric drive device for driving the vehicle between the partition walls, and tip portions of at least one of the pair of lower frames and the pair of upper frames. A pair of lower frames, wherein the pair of lower frames are connected to each other, and are vertically disposed at positions spaced forward from the accommodating vertical wall member. And the other frame pairs in the pair of upper frames are in the high position different from the one of the frame pair is coupled or disposed rearward of the input vertical wall member disposed vertically.

  Preferably, a pair of crash boxes protruding forward from the vertical wall member for input and a bumper beam coupled to the front ends of the pair of crash boxes are preferably provided.

  Preferably, a frame frame for attaching a radiator is arranged in front of the input vertical wall member.

  Preferably, the input vertical wall member includes a first horizontal frame connecting between the pair of lower frames, a second horizontal frame disposed above or below the first horizontal frame, and the first A plurality of vertical frames that connect between one horizontal frame and the second horizontal frame, and may have a frame shape formed by the first horizontal frame, the second horizontal frame, and the plurality of vertical frames. .

  Preferably, it has a floor board member arrange | positioned between the said front partition and the said vertical wall member for accommodation, The said electric drive apparatus is good to be mounted in the said floor board member.

In this invention, the electric drive apparatus containing the battery arrange | positioned at the front part of a vehicle can be arrange | positioned, and the cruising range of a vehicle can be improved. The influence on the loading capacity of the boarding space and the cargo space can be suppressed.
And the electric drive apparatus containing the battery arrange | positioned at the front part of a vehicle can be protected by the double wall by the vertical wall member for accommodation, and the vertical wall member for input. The impact of the collision is input to the input vertical wall member, and the frame between the input vertical wall member and the accommodating vertical wall member buckles, so that the impact can be absorbed.
In particular, since the vertical wall member for input connects the tip portions of one pair of frames of the pair of lower frames and the pair of upper frames to each other and is disposed vertically, the input vertical wall member has a wide planar shape in the vehicle width direction. Can act as an input wall. Therefore, for example, even when the impact is input substantially straight from the front as in a full wrap collision or an offset collision, even when the impact is input from an oblique direction, the impact can be received and supported by the planar input vertical wall member. it can. High collision absorption capability can be obtained by a frame structure that cannot be adopted in the conventional vehicle because the engine is mounted between the pair of lower frames.
Further, the other frame pair is connected or arranged on the rear side of the input vertical wall member at a height position different from that of the one frame pair. Thereby, after the frame between the vertical wall member for input and the vertical wall member for accommodation begins to buckle, the vertical wall member for input is supported by the other frame pair from the rear side. After starting buckling, the function of maintaining the vertical wall member for input in a vertical posture is obtained. Therefore, even when a strong impact is input, the posture of the input vertical wall member can be maintained vertically, and the state in which the impact is input to the input vertical wall member maintained vertically can be maintained. Even when an impact is input from an oblique direction, it continues to be received by the vertical wall member for input, and the input direction of the shock is difficult to change or it is difficult to change so that the impact is input from other than the vertical wall member for input. . It can be expected that an impact that is input from the oblique direction while continuing to receive an impact from the vertical wall member for input can be obtained as high as the impact input from the front direction.

[First Embodiment]
FIG. 1 is a schematic perspective view of an electric vehicle 1 as viewed from above according to a first embodiment of the present invention. FIG. 2 is a schematic perspective view of the electric vehicle 1 of FIG. 1 viewed from the left side. Hereinafter, up and down front and rear and left and right are used with reference to the posture of the electric vehicle 1 in FIG.
The electric vehicle 1 is a kind of vehicle. The electric vehicle 1 drives the motor with the stored power of the battery module. The battery module and the motor are electrically driven devices. Other vehicles include, for example, a hybrid vehicle including an electric drive device and a fuel drive device such as an engine, and an existing vehicle including a fuel drive device.
An electric vehicle 1 in FIG. 1 has a vehicle body 2 having a plurality of skeleton members. The vehicle body 2 in FIG. 1 has a boarding space 3 in which passengers get on, a front chamber 4 on the front side of the boarding space 3, and a luggage room 5 on the rear side of the boarding space 3. The boarding space 3 and the luggage compartment 5 are connected together. The vehicle body 2 is a two-box type. These spaces are defined by a plurality of skeleton members. FIG. 1 illustrates a pair of main frames 6 and a pair of upper side frames 7 among the plurality of skeleton members. Two pairs of wheels 8 and 9 are arranged in the lower part of the vehicle body 2. The pair of front wheels 8 are disposed in the front chamber 4. The pair of rear wheels 9 are arranged in the luggage compartment 5.

  The pair of main frames 6 are skeletal members extending from the front chamber 4 of the vehicle body 2 to the luggage compartment 5. The main frame 6 is a hollow square member made of a high-rigidity steel plate. The main frame 6 extends in the front-rear direction along the bottom surface of the vehicle body 2. The pair of front wheels 8 and the pair of rear wheels 9 are pivotally supported by the pair of main frames 6. The seat 10 in the riding space 3 is directly or indirectly attached to the pair of main frames 6. The main frame 6 protrudes forward from a toe board 11 that partitions the riding space 3 and the front chamber 4. The pair of main frames 6 project forward from the lower portion of the toe board 11 near the center in the left-right direction of the vehicle body 2.

  The pair of upper side frames 7 are skeleton members extending from the front chamber 4 of the vehicle body 2 to the luggage compartment 5. The upper side frame 7 is a hollow square member made of a highly rigid steel plate. The upper side frame 7 extends in the front-rear direction along the upper portion of the vehicle body 2. The pair of upper side frames 7 projects forward from the upper part of the toe board 11 near the left and right side surfaces of the vehicle body 2. The pair of upper side frames 7 protrudes at a position higher than the pair of main frames 6 in the vertical direction of the vehicle body 2. The pair of upper side frames 7 is located on the outer side in the left-right direction with respect to the pair of main frames 6 in the left-right direction of the vehicle body 2. In the front chamber 4, the pair of upper side frames 7 are disposed under the hood. A sheet metal is fixed between the upper side frame 7 and the main frame 6, and a suspension for suspending the front wheel 8 is attached to the sheet metal.

  In general, a pair of crash boxes 12 and a bumper beam 13 are attached to the tips of the pair of main frames 6. The crash box 12 protrudes forward from the pair of main frames 6. The bumper beam 13 is connected to the front ends of the pair of crash boxes 12. A frame 14 is attached on the pair of crash boxes 12. A radiator is attached to the frame frame 14.

FIG. 3 is an explanatory diagram of a drive system in the electric vehicle 1 of FIG.
FIG. 3 is an example of a drive system of the electric vehicle 1. The drive system includes a first battery module 21, a second battery module 22, a DC (Direct Current) / DC converter 23, a front motor 24, a rear motor 25, and a control unit 26 as electric drive devices.

  The first battery module 21 and the second battery module 22 are batteries that store electricity. The battery modules 21 and 22 have a plurality of battery cells that store electricity. In FIG. 1, the second battery module 22 is loaded between the rear seat 10 and the floor surface in the riding space 3. For this reason, the rear sheet 10 is higher than the front sheet 10.

  The front motor 24 is a motor that drives the pair of front wheels 8. The front motor 24 may be a DC motor, for example. The front motor 24 may drive the pair of front wheels 8 directly or indirectly through a transmission or the like. In FIG. 1, the front motor 24 is attached to the pair of main frames 6 in the front chamber 4.

  The rear motor 25 is a motor that drives the pair of rear wheels 9. The rear motor 25 may be a DC motor, for example. The rear motor 25 may drive the pair of rear wheels 9 directly or indirectly through a transmission or the like. In FIG. 1, the rear motor 25 is attached to the pair of main frames 6 in the luggage compartment 5.

  The DC / DC converter 23 is connected to the first battery module 21, the second battery module 22, the front motor 24, the rear motor 25, and the control unit 26. The DC / DC converter 23 supplies the voltage input from the first battery module 21 and the second battery module 22 to the front motor 24 and the rear motor 25. The DC / DC converter 23 may individually boost the DC voltage supplied from the battery modules 21 and 22 and supply the boosted voltage to the front motor 24 and the rear motor 25 individually.

  The control unit 26 controls the operation and stop of the drive system in FIG. 3 based on the operation of the occupant seated on the seat 10. For example, when the accelerator pedal is operated by the passenger, power supply from the DC / DC converter 23 to the front motor 24 and the rear motor 25 is started. Conversely, when the accelerator pedal is not operated, the power supply from the DC / DC converter 23 to the front motor 24 and the rear motor 25 is stopped. Further, the power supplied to the front motor 24 and the rear motor 25 is adjusted according to the operation amount of the accelerator pedal. Thereby, the rotation, stop, and rotation speed of the front motor 24 and the rear motor 25 are controlled. The electric vehicle 1 accelerates from a stopped state, decelerates, and stops according to the rotation of the front motor 24 and the rear motor 25.

By the way, in the electric vehicle 1, the motors 24 and 25 are driven by the electric power stored in the battery modules 21 and 22, and the electric vehicle 1 travels by the driving force of the motors 24 and 25. The cruising distance is limited by the stored power of the battery modules 21 and 22. The electric vehicle 1 may be loaded with a large number of large capacity battery modules 21 and 22. For this reason, in the electric vehicle 1, a large number of battery modules 21 and 22 are generally loaded in the boarding space 3 and the luggage compartment 5. Also in FIG. 1, the second battery module 22 is loaded between the rear seat 10 and the floor surface in the riding space 3.
However, when all the batteries are arranged in the boarding space 3 or the cargo compartment 5 of the electric vehicle 1, a trade-off is established between the loading capacity of the boarding space 3 or the cargo compartment 5 and the cruising distance. In order to increase the cruising distance of the electric vehicle 1, it is necessary to sacrifice the loading capacity of the riding space 3 and the luggage compartment 5 in order to load a large number of battery modules 21 and 22. Also in FIG. 1, for example, when the first battery module 21 and the second battery module 22 are stacked in the riding space 3, the height of the rear seat 10 must be further increased. The comfort of the riding space 3 is impaired.
As described above, in the vehicle such as the electric vehicle 1, it is required to improve the cruising distance of the vehicle without sacrificing the boarding space 3 and the cargo space 5. Therefore, it is conceivable to arrange an electric drive device such as a battery in the front chamber 4 of the vehicle body 2 such as the engine chamber. Thereby, the boarding space 3 and the luggage compartment 5 are not sacrificed.
However, when an electric drive device such as a battery is disposed in the front chamber 4 of the vehicle body 2, there is a possibility that the collision performance of the vehicle body 2 may be affected as compared with the case where it is disposed in the riding space 3 or the luggage compartment 5. For example, there are a full-lap collision test and an offset collision test in the automobile collision test including the electric vehicle 1. When a battery or the like is disposed in the boarding space 3 or the like, the existing vehicle body 2 having a fuel drive device can be used as it is, and these tests can be handled.
As described above, in the vehicle such as the electric vehicle 1, it is required to improve the cruising distance of the vehicle while suppressing the influence on the collision performance of the vehicle or the loading capacity of the passenger space 3 and the luggage compartment 5, for example.

  Therefore, the present embodiment provides a vehicle body structure that can cope with a full lap collision test and an offset collision test even if electric drive devices such as battery modules 21 and 22 are arranged in the front chamber 4 of the vehicle body 2. In particular, the vehicle body 2 of an existing automobile equipped with a fuel drive device provides a vehicle body structure that could not be employed due to the need to arrange an engine or the like in the front chamber 4 of the vehicle body 2. This will be described in detail below.

  The following description will be given with reference to FIG. 4 together with FIGS. FIG. 4 is a schematic perspective view of the electric vehicle 1 of FIG. 1 viewed from the front side.

  As shown in FIGS. 1 and 2, in the electric vehicle 1 of the present embodiment, the first battery module 21, the DC / DC converter 23, the control unit 26, and the front motor 24 are installed in the front chamber 4 of the vehicle body 2. The

An accommodating vertical wall member 31 is erected at the central portion of the pair of main frames 6 protruding forward from the toe board 11.
The accommodating vertical wall member 31 has a height from the pair of main frames 6 to the pair of upper side frames 7. The accommodating vertical wall member 31 connects the central part of the pair of main frames 6 and the central part of the pair of upper side frames 7 to each other. The accommodating vertical wall member 31 may be, for example, a highly rigid square member assembled in a rectangular frame shape. The accommodating vertical wall member 31 may be a steel plate for dust prevention or the like.

A floor board member 32 is disposed between the accommodating vertical wall member 31 and the toe board 11.
On the floor board member 32, the first battery module 21, the DC / DC converter 23, and the control unit 26 are mounted side by side. The front motor 24 is disposed below the floor board member 32. The front motor 24 is attached to the pair of main frames 6.
An electric drive device such as the first battery module 21 can be accommodated between the accommodating vertical wall member 31 and the toe board 11.
Further, the rigidity between the accommodating vertical wall member 31 and the toe board 11 can be improved by the floor plate member 32. The rear portions of the pair of main frames 6 are less likely to buckle than the front portions. The protection function of the electric drive device can be improved.

An input vertical wall member 41 is coupled between the front ends of the pair of main frames 6 and the pair of crash boxes 12.
As shown in FIG. 4, the input vertical wall member 41 includes a first horizontal frame 42, a second horizontal frame 43, a first vertical frame 44, and a second vertical frame 45. These frames 42 to 45 may be formed of a highly rigid material.
The first horizontal frame 42 is a horizontally long frame member that is long in the left-right direction of the vehicle body 2. The first horizontal frame 42 is attached to the front ends of the pair of main frames 6. A pair of crash boxes 12 are attached to the front side of the first horizontal frame 42. Thus, the pair of main frames 6 are connected.
The first vertical frame 44 and the second vertical frame 45 are erected on both ends of the horizontally long first horizontal frame 42 in the left-right direction.
The second horizontal frame 43 is a horizontally long frame member that is long in the left-right direction of the vehicle body 2. Both ends in the left-right direction of the second horizontal frame 43 are connected to the upper end of the first vertical frame 44 and the upper end of the second vertical frame 45. On the rear side of the second horizontal frame 43, the tips of the pair of upper side frames 7 are connected.

As described above, the input vertical wall member 41 has a frame shape formed by the first horizontal frame 42, the second horizontal frame 43, the first vertical frame 44, and the second vertical frame 45. By making the input vertical wall member 41 into a frame structure, the input vertical wall member 41 is lighter while obtaining the rigidity of the input vertical wall member 41 than when the input vertical wall member 41 is formed of a single metal plate, for example. it can.
The input vertical wall member 41 functions as a vertical wall that connects the tip portions of the pair of main frames 6 and the tip portions of the pair of upper side frames 7 to each other.
The input vertical wall member 41 is arranged vertically at a position spaced forward from the accommodating vertical wall member 31. The input vertical wall member 41 can function as a planar member to which an impact at the time of collision is input. A double wall structure is realized in the front chamber 4 of the vehicle body 2.
Further, the input vertical wall member 41 has a frame structure of a vertically placed rectangular frame as shown in FIG. As shown in FIGS. 2 and 1, a pair of main frames 6 and a pair of upper side frames 7 extend rearward from the frame structure of the rectangular frame. Further, the pair of main frames 6 and the pair of upper side frames 7 are connected to each other by a housing vertical wall member 31. A pair of main frames 6 and a pair of upper side frames 7 extend rearward from the double wall structure in the front chamber 4 of the vehicle body 2. An electric drive device including the first battery module 21 is mounted inside the frame. Although the electric drive device including the first battery module 21 is mounted in the front chamber 4 of the vehicle body 2, it can be disposed in a space that can be highly protected in the same manner as the riding space 3.

As described above, in the present embodiment, the electric drive device including the first battery module 21 is disposed in the front chamber 4 of the vehicle body 2. Therefore, it is not necessary to mount all the battery modules 21 and 22 in the boarding space 3 and the luggage compartment 5. The cruising distance of the vehicle can be improved while suppressing the influence on the loading capacity of the boarding space 3 and the cargo space 5.
Moreover, in the present embodiment, a double wall structure is realized by the accommodating vertical wall member 31 and the input vertical wall member 41 on the front side of the electric drive device including the first battery module 21. Electric drive devices such as the first battery module 21 disposed in the front chamber 4 of the vehicle body 2 can be suitably protected. The impact of the collision is input to the input vertical wall member 41. The pair of main frames 6 and the pair of upper side frames 7 are buckled between the input vertical wall member 41 and the accommodating vertical wall member 31. Thereby, an impact can be absorbed.

  In particular, the input vertical wall member 41 is arranged vertically and connects the tip portions of both the pair of main frames 6 and the pair of upper side frames 7 to each other. A pair of main frames 6 are connected by a first horizontal frame 42, and a pair of upper side frames 7 are connected by a second horizontal frame 43. The input vertical wall member 41 can function as a planar input wall that is wide in the left-right direction in the front chamber 4 of the vehicle body 2. Therefore, for example, not only when the impact is input substantially straight from the front as in the case of a full wrap collision or offset collision, but also when the impact is input from an oblique direction, these impacts are applied regardless of the input direction of the impact. Can be received and supported by the planar vertical wall member 41 for input. In a vehicle in which the engine is mounted in the front chamber 4, it is expected to obtain a high collision absorption capability due to the frame structure that could not be employed because the pair of main frames 6 could not be connected by the frame member. it can.

  A pair of main frames 6 and a pair of upper side frames 7 are connected to the rear side of the input vertical wall member 41 at different height positions. Thereby, even after these frames begin to buckle between the vertical wall member 41 for input and the vertical wall member 31 for accommodation, the vertical wall member 41 for input can be supported from the rear side in the left-right direction and the vertical direction. it can. Even after the frame starts to buckle, the input vertical wall member 41 can be maintained in a standing posture. Therefore, even when a strong impact is input, the posture of the input vertical wall member 41 can be maintained vertically, and the impact can be continuously received by the input vertical wall member 41 maintained vertically. An impact input from an oblique direction can be continuously received by the input vertical wall member 41. During the collision, the input direction of the impact is changed, or the impact is changed so that the impact is input from other than the input vertical wall member 41. Since the input vertical wall member 41 can continue to receive an impact, a high impact absorption capability can be obtained for an impact input from an oblique direction as well as an impact input from the front direction.

[Second Embodiment]
Next, the electric vehicle 1 according to the second embodiment will be described.
The electric vehicle 1 according to the second embodiment is the same as that of the first embodiment except that the frame structure of the vehicle body 2 with respect to the input vertical wall member 41 is different. Hereinafter, the same names and reference numerals as those in the first embodiment are used, and descriptions overlapping with those in the first embodiment are omitted.

FIG. 5 is a schematic perspective view of the electric vehicle 1 as viewed from above according to the second embodiment. FIG. 6 is a schematic perspective view of the electric vehicle 1 of FIG. 5 as viewed from the left side.
As shown in FIG. 5 and FIG. 6, in the electric vehicle 1 of the present embodiment, a double wall structure is realized in the front chamber 4 of the vehicle body 2 by the accommodating vertical wall member 31 and the input vertical wall member 41. .
The structure of the accommodating vertical wall member 31 and the connecting structure of the accommodating vertical wall member 31 to the pair of main frames 6 and the pair of upper side frames 7 are the same as those in the first embodiment.
As in FIG. 4, the input vertical wall member 41 has a vertical frame structure including a first horizontal frame 42, a second horizontal frame 43, a first vertical frame 44, and a second vertical frame 45. The first horizontal frame 42 is connected between the pair of main frames 6 and the pair of crash boxes 12.
However, unlike the first embodiment, the ends of the pair of upper side frames 7 are spaced apart from the rear side of the second horizontal frame 43. The ends of the pair of upper side frames 7 are not connected to the second horizontal frame 43.
Other configurations are the same as those in the first embodiment, and a description thereof will be omitted.

As described above, in the present embodiment, unlike the first embodiment, the ends of the pair of upper side frames 7 are not connected to the second horizontal frame 43. However, the tips of the pair of upper side frames 7 are located on the rear side of the second horizontal frame 43. Therefore, similarly to the first embodiment, the electric drive device including the first battery module 21 mounted in the front chamber 4 of the vehicle body 2 can be highly protected similarly to the riding space 3 by the double wall structure. Can be placed.
In particular, on the rear side of the input vertical wall member 41, the pair of upper side frames 7 are disposed at different height positions from the pair of main frames 6. Thus, after the pair of main frames 6 starts to buckle between the input vertical wall member 41 and the accommodating vertical wall member 31, the input vertical wall member 41 is moved to the pair of upper side frames 7 and the pair of main frames 6. The frame 6 can be supported from the rear side in the left-right direction and the up-down direction. Even after the frame starts to buckle, the input vertical wall member 41 can be maintained in the vertical posture.
As a result, an impact absorption capability equivalent to that of the first embodiment can be obtained.

  The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications or changes can be made without departing from the spirit of the invention.

For example, in the above embodiment, the input vertical wall member 41 extends on the pair of main frames 6. In addition to this, for example, the input vertical wall member 41 may extend vertically from the pair of main frames 6 or may extend only to the lower side. Even in these cases, the pair of upper side frames 7 can be connected or arranged on the rear side of the input vertical wall member 41 at a height position different from that of the pair of main frames 6. Thereby, the vertical wall member 41 for input can be maintained vertical at the time of a collision.
Furthermore, for example, the input vertical wall member 41 may be connected to only the pair of upper side frames 7. In this case, the pair of main frames 6 may be separated from the rear side of the input vertical wall member 41 at a height position different from that of the pair of upper side frames 7. Thereby, the function to maintain the vertical wall member 41 for input vertically is obtained.

  In the above embodiment, the input vertical wall member 41 and the accommodating vertical wall member 31 are connected to the pair of main frames 6 and the pair of upper side frames 7. In addition, for example, the input vertical wall member 41 and the accommodating vertical wall member 31 may be coupled to other frame members extending forward from the toe board 11.

  In the above embodiment, the input vertical wall member 41 connects the tip portions of the pair of main frames 6 and the tip portions of the pair of upper side frames 7 to each other. In addition, for example, the input vertical wall member 41 may connect only one of the tip portions of the pair of main frames 6 and the tip portions of the pair of upper side frames 7 to each other.

  The above embodiment is an example in which the present invention is applied to the electric vehicle 1. In addition, for example, the present invention may be applied to a vehicle such as a hybrid vehicle. In particular, if the driving force of the motor is improved in the future, the engine of the hybrid vehicle may be downsized. The small engine can be disposed in the front chamber 4 even when the pair of main frames 6 are connected by the input vertical wall member 41. The present invention can also be applied to vehicles other than automobiles.
