Technical Field

The present invention relates to a battery fixing structure, and more particularly to a battery fixing structure for fixing a battery for an auxiliary device mounted on an automobile.

Background

Conventionally, techniques such as the following have been disclosed: in the high-voltage battery 42 mounted on the center console, a structure serving also as a cooling duct is provided below the battery, and when an impact is input in a lateral direction, the duct is bent to absorb the impact caused by the lateral collision (see, for example, patent document 1).

As another technique, the following technique is disclosed: by appropriately setting the arrangement of the welding points and the ribs 75 in the protective case that protects the high-voltage battery 32 mounted on the center console, the ribs 75 exert a strength function when an input collision occurs, and thereby absorb an impact in the front-rear direction and the side direction (see, for example, patent document 2).

Disclosure of Invention

Problems to be solved by the invention

However, in the technique of the cited document 1, since it is necessary to provide a pipe for absorbing impact under the center console, the center console is enlarged in the height direction, so that the space is increased. In addition, the center console is also often assumed to be used by the driver for arm placement, and there is a high possibility that such use is hindered by the restriction in the height direction.

In the technique of the cited document 2, the impact absorbing member is not placed under the battery, but a surrounding metal structure is provided with strength. Therefore, although there is no restriction on the height direction of the center console, there is a problem that the surrounding metal structure becomes a very thick and heavy structure.

Therefore, a battery fixing structure is desired: for example, when a load is input from the vehicle width direction due to a side collision or the like, the impact on the battery can be absorbed without forming a large protection space.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a battery fixing structure capable of absorbing impact on a battery without forming a large protection space or a high-cost structure that increases the weight of the surrounding.

Means for solving the problems

In order to achieve the above object, the present invention provides a battery fixing structure including: a battery; a vehicle seat provided in a vehicle width direction; and a fixing member for fixing the battery between the vehicle seats, wherein the fixing member includes a contact member that comes into contact with the battery to support the battery between the vehicle seats, and the contact member deforms when a load equal to or greater than a predetermined value is input from a vehicle width direction, and is capable of moving the battery in the vehicle width direction.

Accordingly, when a load equal to or greater than a predetermined value is input in the vehicle width direction, the contact member deforms, so that the impact due to the load input in the vehicle width direction can be absorbed, a space in which the battery can move can be secured, and the battery can be moved in a direction away from the load input direction. As a result, the battery can be protected from the impact at the time of a side collision, and the occurrence of the secondary damage to the occupant in the vehicle, which is expected due to the breakage of the battery, can be prevented.

In the above configuration, when a load equal to or greater than a predetermined value is input from the vehicle width direction, the contact member on the side opposite to the load input direction is deformed, and the battery can be moved in the vehicle width direction.

Accordingly, when a load equal to or greater than a predetermined value is input in the vehicle width direction, the contact member on the side opposite to the load input direction deforms, whereby the load input in the vehicle width direction is absorbed, a space in which the battery can move is secured, and the battery can be moved in a direction away from the load input direction.

In the above configuration, the contact member includes: an upper pressing portion that inputs a force to the battery below a floor of the vehicle; and a contact portion that receives a force in the vehicle width direction and deforms when a load equal to or greater than a predetermined value is received in the vehicle width direction.

Accordingly, since the upper portion of the battery can be pressed by the upper pressing portion, even when a load is input from the vehicle width direction, the movement of the battery in the vertical direction can be restricted, and the battery can be smoothly moved in the width direction.

In the above configuration, the battery is disposed closer to one of the vehicle seats with reference to a center line in a vehicle width direction.

Accordingly, by bringing the battery closer to one of the vehicle seats, maintenance of the battery can be easily performed.

In the above configuration, the battery is mounted on a center console, and a side of the center console where the battery is disposed is formed to be detachable, and an opening through which the battery is exposed is formed.

Accordingly, since the opening for exposing the battery is formed in the center console, maintenance or replacement of the battery can be easily performed through the opening.

In the above configuration, the fixing member further includes a side plate that protects a side surface of the battery, and a side plate on a side where the battery is disposed is formed to have a higher strength than a side plate on an opposite side to the side where the battery is disposed.

Accordingly, the side plate on the side where the battery is disposed is formed to have a higher strength than the side plate on the opposite side to the side where the battery is disposed, and therefore, the battery can be protected even when a load is input from the side where the protection space is small.

In the above configuration, a length in the vehicle width direction of a space between the battery and the vehicle seat, which is formed by the battery moving in the vehicle width direction when a load is input from the vehicle width direction, is longer than a length of a seat pipe located below the vehicle seat and pushed out in a direction toward the battery when a load is input from the vehicle width direction.

Thus, the seat tube can be prevented from penetrating into the battery and damaging the battery.

In the structure, a portion of the side plate located at a position where the side plate can overlap with the seat tube in a side view has a higher strength than other portions.

Accordingly, the side plate located at the position overlapping the seat tube in a side view is formed to have a higher strength than the other portions, and therefore, the battery can be prevented from being damaged by the seat tube.

In the above configuration, the fixing member further includes a battery support portion on which a battery is placed, and the battery support portion is formed so as to be inclined at a portion connected to the side plate.

Accordingly, even if the side panel falls down due to the inclination of the battery support portion when a load is input from the vehicle width direction, the side panel can be prevented from being fixed and detached.

In the above configuration, the battery is a battery for an auxiliary machine.

Accordingly, the present invention can be applied to a battery for an auxiliary.

Effects of the invention

According to the present invention, the contact member deforms, so that the impact due to the load input from the vehicle width direction can be absorbed, and the space in which the battery can move can be secured, and the battery can be moved in the direction away from the load input direction. As a result, the battery can be protected from the impact at the time of a side collision, and the occurrence of the secondary damage to the occupant in the vehicle, which is expected due to the breakage of the battery, can be prevented.

Further, since a space can be secured on the load input surface side by moving the battery in the vehicle width direction, it is possible to secure a large protection space on both the left and right sides of the battery, and further, it is not necessary to add a heavy and expensive structure to the periphery, and it is possible to significantly reduce the restriction on the installation space of the battery, and it is also possible to reliably protect the battery when a load is input.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 2 is an exploded perspective view showing the battery fixing structure of the present embodiment. Fig. 3 is a perspective view showing the battery fixing structure of the present embodiment as viewed from the left side.

Fig. 5 is a front view showing the battery fixing structure of the present embodiment. Fig. 6 is a perspective view showing a battery fixing structure of the present embodiment.

In fig. 5, the right side in the figure is the driver seat side, the left side in the figure is the passenger seat side, in fig. 6, the lower side in the figure is the driver seat side, and the upper side in the figure is the passenger seat side. That is, fig. 5 and 6 each show an example in which the driver seat is provided on the left side of the automobile 11.

The battery 10 in the present embodiment is a battery 10 for auxiliary equipment mounted on an automobile as an electric vehicle such as a hybrid vehicle or an electric vehicle. The battery 10 is a secondary battery such as a lithium ion battery that can be charged and discharged.

As shown in fig. 1, 5, and 6, in the present embodiment, the automobile 11 includes a floor panel 12. On the upper surface side of the floor 12, a driver seat 13 and a passenger seat 14 as vehicle seats are arranged side by side. A center console 15 is disposed between the driver seat 13 and the passenger seat 14.

A seat support plate 16 that supports the driver seat 13 and the passenger seat 14, respectively, is provided on the upper surface side of the floor 12. The seat support plate 16 is formed in a plate shape extending in the front-rear direction, and a pair of seat support plates 16 for supporting the driver seat 13 and a pair of seat support plates 16 for supporting the passenger seat 14 are provided at a predetermined interval in the vehicle width direction. A seat pipe 17 is provided between the seat support plates 16 in front of the pair of seat support plates 16 supporting the driver's seat 13. Similarly, a seat pipe 17 is provided between the seat support plates 16 in front of the pair of seat support plates 16 that support the front passenger seat 14.

As shown in fig. 5, a seating surface frame 18 of the driver seat 13 and a seating surface frame 18 of the passenger seat 14 are provided above the respective seat support plates 16. Thus, the driver seat 13 and the passenger seat 14 are supported by the seat support plate 16 and the seat cushion frame 18 provided with the seat pipe 17. The driver seat 13 and the passenger seat 14 are movable in the front-rear direction, and the seating positions can be adjusted.

A battery housing 19 is disposed in front of the center console 15, and the battery 10 is housed in the battery housing 19.

A side cover, not shown, is detachably provided on a side surface of the battery housing portion 19 disposed in the center console 15. By detaching the side cover, an opening (not shown) is formed in the side surface of the center console 15, and the battery 10 is exposed through the opening, so that the maintenance of the battery 10 can be performed. As will be described later, in the present embodiment, the battery 10 serving as a battery support plate is disposed on the front passenger seat 14 side, and the side cover is formed on the front passenger seat 14 side.

Next, the battery fixing structure will be described in detail.

As shown in fig. 2 to 4, the battery support plate 20 is provided as a battery support portion for substantially horizontally holding the battery 10. Although not shown, the battery support plate 20 is fixed to the floor panel 12 by bolts B.

The battery support plate 20 includes a substantially flat plate-shaped mounting plate 21 on which the battery 10 is mounted, and fixing flanges 22 extending obliquely downward are integrally provided on both sides of a rear side end portion of the mounting plate 21. The fixing flange 22 is formed at substantially the same position as the installation position of the seat pipe 17 in the front-rear direction. That is, the fixing flange 22 is formed at a position that can overlap the seat pipe 17 when viewed from the side.

As shown in fig. 5, the battery support plate 20 is disposed between the seat support plate 16 on the driver seat 13 side and the seat support plate 16 on the passenger seat 14 side, and in the present embodiment, the battery support plate 20 is disposed close to the seat support plate 16 on the passenger seat 14 side. That is, as shown in fig. 5, the gap a between the seat support plate 16 on the passenger seat 14 side and the battery is formed smaller than the gap b between the seat support plate 16 on the driver seat 13 side and the battery.

In the battery 10 supported by the battery support plate 20, the length in the vehicle width direction of the space between the battery 10 and the driver's seat 13 or the front passenger's seat 14, which is formed by the battery 10 moving in the vehicle width direction when a load is input from the vehicle width direction, is formed to be longer than the length of the seat pipe 17 pushed out in the direction toward the battery 10 when a load is input from the vehicle width direction.

That is, the intervals between the battery 10 and the driver seat 13 and the passenger seat 14 are set to the following degrees: even if a load is input from the vehicle width direction and the seat pipe 17 is pushed out toward the battery 10, the seat pipe 17 does not apply a load to the battery 10.

A left side plate 30 is welded to one side of the battery support plate 20 (the driver seat 13 side in the present embodiment). A right side plate 40 is disposed on the other side of the battery support plate 20.

A lower fixing piece 31 projecting obliquely downward is formed at the lower end portion of the left side plate 30, and the left side plate 30 and the battery support plate 20 are fixed to the floor panel 12 by fixing the lower fixing piece 31 and the fixing flange 22 with a bolt B.

Two lower contact members 32 as contact members are provided at a predetermined interval in the front-rear direction on the inner lower side of the left side plate 30. The lower contact member 32 is constituted by: a mounting piece 33 mounted on the left side plate 30; a contact piece 34 that contacts the lower side of the battery 10; and a connecting piece 35 that connects the mounting piece 33 and the contact piece 34 obliquely.

The lower contact member 32 has a function of supporting the lower side surface of the battery 10 by the contact piece 34 contacting the lower side surface of the battery 10, and allowing the connection piece 35 to deform and move the battery 10 in the vehicle width direction when a load of a predetermined value or more is input to the battery 10 in the vehicle width direction.

The left side plate 30 has a height dimension slightly protruding from the upper surface of the battery 10, and an upper fixing portion 36 is formed at the upper end portion of the left side plate 30.

The right side plate 40 is formed by overlapping two inner right side plates 41 and outer right side plates 42, and has a higher strength than the left side plate 30. That is, the battery support plate 20 is disposed between the seat support plate 16 on the driver seat 13 side and the seat support plate 16 on the passenger seat 14 side, and in the present embodiment, the battery support plate 20 is disposed close to the seat support plate 16 on the passenger seat 14 side. Therefore, although a load in the width direction is input to the seat tube 17 on the front passenger seat 14 side due to a side collision or the like, the seat tube 17 may collide with the right side plate 40, but the strength of the right side plate 40 is increased relative to the strength of the left side plate 30, so that damage to the right side plate 40 by the seat tube 17 can be reduced.

A lower fixing piece 43 projecting obliquely downward is formed at the lower end portion of the inner right side plate 41, and the inner right side plate 41 is fixed to the battery support plate 20 by fixing the lower fixing piece 43 to the fixing flange 22 with a bolt B. Further, an upper fixing piece 44 is provided at the upper end of the inner right side plate 41.

Since the fixing flange 22 of the battery support plate 20 is formed to extend obliquely downward and the right side plate 40 is fixed to the fixing flange 22 by the bolt B, the fixing flange 22 and the right side plate 40 are not fixed to each other even if the right side plate 40 or the left side plate 30 falls due to the inclination of the fixing flange 22 when a load is input from the vehicle width direction.

Further, since the fixing flange 22 is formed at a position substantially equal to the installation position of the seat pipe 17 in the front-rear direction and the right and left side plates 40 and 30 are fixed to the fixing flange 22 by the bolts B, the number of fixing portions by the bolts B at the portion corresponding to the seat pipe 17 can be increased, and the strength of the portion corresponding to the seat pipe 17 can be increased.

An upper support piece 45 extending obliquely upward is provided in a protruding manner at the upper end of the outer right side plate 42. An upper contact member 46 as a contact member is attached to the upper support piece 45. The upper contact member 46 is constituted by: a main body plate 47 abutting against the upper surface of the upper support piece 45; an upper pressing plate 48 as an upper pressing portion extending from both sides of the main body plate 47; and a contact plate 49 as a contact portion extending downward from both end portions.

The contact plate 49 is in contact with the upper side surface of the battery 10, supports the upper side surface of the battery 10, and has a function of deforming to move the battery 10 in the vehicle width direction when a load of a predetermined value or more is input to the battery 10 in the vehicle width direction.

Further, since the upper portion of the battery 10 can be pressed by the upper pressing plate 48, excessive movement of the battery 10 in the vertical direction can be restricted even when a load is input from the vehicle width direction, and the battery 10 can be smoothly moved in the width direction.

In addition, the term "deformed" in the present description includes a case where the deformation is caused by the input of the load and the original shape is restored after the deformation.

An upper support member 50 is provided between the upper fixing portion 36 of the left side plate 30 and the upper fixing piece 44 of the inner right side plate 41. The upper support member 50 is formed into a substantially trapezoidal shape in plan view, and the side having a short width dimension is fixed to the upper fixing piece 44 by a bolt B, and the side having a long width dimension is fixed to the upper fixing portion 36 by a bolt B.

The upper support member 50 supports the upper portion of the battery 10.

As shown in fig. 2, a front plate 51 is provided in front of the battery 10, and one side of the front plate 51 is joined to the left side plate 30 by welding. The other side of the front plate 51 is fixed to and held by the right side plate 40 with a bolt B.

A rear plate 52 is provided behind the battery 10, and both sides of the rear plate 52 are fixed to and held by the right and left side plates 40, 30 with bolts B.

With this configuration, the periphery of the battery 10 is held by the right side plate 40, the left side plate 30, the front plate 51, and the rear plate 52, and the upper portion of the battery 10 is held by the upper support member 50.

The left fixing member 60 is constituted by the left side plate 30 and the lower contact member 32 on the left side of the battery 10, and the right fixing member 61 is constituted by the right side plate 40 and the upper contact member 46 on the right side of the battery 10.

In the above embodiment, the description has been given of the case where the battery support plate 20 is disposed close to the seat support plate 16 on the passenger seat 14 side, but the battery support plate 20 may be disposed close to the seat support plate 16 on the driver seat side. In this case, the battery fixing structure may be configured to be reversed left and right.

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

In the present embodiment, when a load equal to or greater than a predetermined value is input in the vehicle width direction due to a side collision of the automobile 11 or the like, the connecting piece 35 of the lower contact member 32 or the contact plate 49 of the upper contact member 46 deforms, and thereby, it is possible to absorb an impact caused by the load input in the vehicle width direction, and it is possible to secure a space in which the battery 10 can move, and it is possible to move the battery 10 in a direction away from the load input direction.

For example, when a load is input from the passenger seat 14 side, the connecting piece 35 of the lower contact member 32 of the left side plate 30 on the driver seat 13 side opposite to the passenger seat 14 is deformed, and thus a space for the battery 10 to move toward the driver seat 13 side is secured, and the battery 10 can move in the vehicle width direction.

When a load is input from the driver seat 13 side, the contact plate 49 of the upper contact member 46 of the right side plate 40 on the passenger seat 14 side opposite to the driver seat 13 side is deformed, so that a space for the battery 10 to move toward the passenger seat 14 side is secured, and the battery 10 can move in the vehicle width direction.

By allowing the battery 10 to move when a load is input from the width direction in this manner, the battery 10 provided in the center console 15 can be protected from an impact at the time of a side collision, and occurrence of a secondary injury to an occupant in the vehicle, which is expected due to breakage of the battery 10, can be prevented.

Further, since a space can be secured on the load input surface side by moving the battery 10 in the vehicle width direction, it is possible to secure a large protection space on both the left and right sides of the battery 10, and it is possible to significantly reduce the restriction on the installation space of the battery 10 and to reliably protect the battery 10 when a load is input.

Further, since the battery 10 is disposed close to the front passenger seat 14, the protection space on the front passenger seat 14 side is smaller than that on the driver seat 13 side, but in the present embodiment, the right side plate 40 is configured by overlapping two inner right side plates 41 and two outer right side plates 42, and the strength of the right side plate 40 is increased relative to the left side plate 30, so that the battery 10 can be protected even when a load is input from the front passenger seat 14 side having a small protection space.

In addition, in the battery 10, the length in the vehicle width direction of the space between the battery 10 and the driver's seat 13 or the passenger's seat 14, which is formed by the battery 10 moving in the vehicle width direction when a load is input from the vehicle width direction, is formed to be longer than the length of the seat pipe 17 pushed out in the direction toward the battery 10 when a load is input from the vehicle width direction, so that it is possible to prevent the seat pipe 17 from penetrating the battery 10 and damaging the battery 10.

Further, since the right side plate 40 and the left side plate 30 which are positioned to overlap the seat tube 17 in a side view are formed to have higher strength than other portions, the battery 10 can be prevented from being damaged by the seat tube 17. Further, since the fixing flange 22 for supporting the battery 10 is formed to extend obliquely downward and the right side plate 40 is fixed to the fixing flange 22 by the bolt B, when a load is input from the vehicle width direction, the fixing flange 22 is inclined, and even if the right side plate 40 falls, the fixing of the fixing flange 22 to the right side plate 40 can be prevented from being released and the side surface protection strength can be prevented from being lowered. The same effect can be obtained also with respect to the fixing flange 22 and the left side plate 30 by welding and fixing with the bolt B.

As described above, in the present embodiment, the fixing member includes the lower contact member 32 and the upper contact member 46 (contact members) that are in contact with the battery 10 and support the battery 10 between the driver seat 13 and the passenger seat 14 (vehicle seat), and the lower contact member 32 and the upper contact member 46 are deformed when a load equal to or greater than a predetermined value is input from the vehicle width direction, and the battery 10 can be moved in the vehicle width direction.

Accordingly, when a load equal to or greater than a predetermined value is input in the vehicle width direction due to a side collision or the like of the automobile 11, the lower contact member 32 or the upper contact member 46 deforms, so that it is possible to absorb an impact caused by the load input in the vehicle width direction, ensure a space in which the battery 10 can move, and move the battery 10 in a direction away from the load input direction. As a result, battery 10 can be protected from impact at the time of a side collision, and occurrence of secondary damage to the vehicle occupant, which is expected due to breakage of battery 10, can be prevented.

Further, since a space can be secured on the load input surface side by moving the battery 10 in the vehicle width direction, it is possible to secure a large protection space on both the left and right sides of the battery 10, and further, it is not necessary to add a heavy and expensive structure to the surroundings, and it is possible to significantly reduce the restriction on the installation space of the battery 10 and also to reliably protect the battery 10 when a load is input.

In the present embodiment, when a load equal to or greater than a predetermined value is input from the vehicle width direction, the lower contact member 32 or the upper contact member 46 (contact member) deforms the upper contact member 46 or the lower contact member 32 on the side opposite to the load input direction, and the battery 10 can be moved in the vehicle width direction.

Accordingly, when a load equal to or greater than a predetermined value is input in the vehicle width direction, the lower contact member 32 or the upper contact member 46 on the side opposite to the load input direction deforms, so that the impact due to the load input in the vehicle width direction can be absorbed, a space in which the battery 10 can move can be secured, and the battery 10 can be moved in a direction away from the load input direction.

In the present embodiment, the upper contact member 46 (contact member) includes: an upper pressing plate 48 (upper pressing portion) that inputs a force to the battery 10 below the floor of the vehicle; and a contact plate 49 (contact portion) that receives a force in the vehicle width direction and deforms when a load greater than or equal to a predetermined value is received in the vehicle width direction.

Accordingly, since the upper portion of the battery 10 can be pressed by the upper pressing plate 48, the movement of the battery 10 in the vertical direction can be restricted even when a load is input from the vehicle width direction, and the battery 10 can be smoothly moved in the width direction.

In the present embodiment, the battery 10 is disposed on a side close to the driver seat 13 or the passenger seat 14 with respect to the center line in the vehicle width direction.

This makes it possible to easily perform maintenance of the battery 10 by approaching one of the driver seat 13 and the passenger seat 14.

In the present embodiment, the battery 10 is mounted on the center console 15, and the center console 15 is formed so that the side where the battery 10 is disposed close to the center console 15 is detachable and an opening for exposing the battery 10 is formed.

This allows easy maintenance or replacement of the battery 10 through the opening.

In the present embodiment, the fixing member further includes a right side plate 40 and a left side plate 30 (side plates) that protect the side surfaces of the batteries 10, and the left side plate 30 on the side where the batteries 10 are disposed is formed to have a higher strength than the right side plate 40 on the opposite side to the side where the batteries 10 are disposed.

Thus, the right side plate 40 is formed by overlapping the inner right side plate 41 and the outer right side plate 42, and the strength of the right side plate 40 is increased relative to the left side plate 30, so that the battery 10 can be protected even when a load is input from the front passenger seat 14 side having a small protection space.

In the present embodiment, the length in the vehicle width direction of the space between the battery 10 and the driver's seat 13 and the passenger's seat 14 (vehicle seat) formed by the battery 10 moving in the vehicle width direction when a load is input from the vehicle width direction is longer than the length of the seat pipe 17 located below the driver's seat 13 and the passenger's seat 14 and pushed out in the direction of the battery 10 when a load is input from the vehicle width direction.

This prevents the seat tube 17 from penetrating the battery 10 and damaging the battery 10.

In the present embodiment, the strength of the portion of the right side plate 40 and the left side plate 30 (side plates) that can overlap the seat tube 17 in a side view is stronger than the strength of the other portions.

Thus, the strength of the right and left side plates 40 and 30 positioned so as to overlap the seat tube 17 in a side view is higher than the strength of the other portions, and therefore, the battery 10 can be prevented from being damaged by the seat tube 17.

In the present embodiment, the fixing member further includes a battery support plate 20 (battery support portion) on which the battery 10 is placed, and the fixing flange 22 of the battery support plate 20 is formed so as to be inclined at a portion connected to the right side plate 40 and the left side plate 30 (side plates).

Thus, when a load is input from the vehicle width direction, even if the right side plate 40 or the left side plate 30 falls down, the fixing of the fixing flange 22 to the right side plate 40 or the left side plate 30 can be prevented from being released and the strength can be prevented from being lowered due to the inclination of the fixing flange 22.

The present invention has been described above with reference to the embodiments, but the present invention is not limited to the embodiments. Since the present invention is described by way of example only, it is possible to arbitrarily change and apply the present invention without departing from the scope of the present invention.

In the above embodiment, the case where the gap a between the seat support plate 16 on the passenger seat 14 side and the battery is formed smaller than the gap b between the seat support plate 16 on the driver seat 13 side and the battery has been described, but the gap b between the seat support plate 16 on the driver seat 13 side and the battery may be formed smaller. In this case, the strength of the left side plate on the driver seat 13 side may be increased.
