Description

The present invention relates to a storage battery unit having a connection structure and a wiring structure.

Patent document 1 discloses a connector fitting device for a pluggable electronic device that includes a first connector attached to the electronic device and a second connector attached to a shelf that stores the electronic device and that couples with the first connector.

JP 2002-093523 A

In the connector fitting device, both the first connector and the second connector are supported in a floating structure. This makes it difficult to couple the first connector and the second connector, which may reduce the ease of assembly of an electronic device to which the connector fitting device is applied.

The objective of the present disclosure is to provide a connection structure that can suppress deterioration in the assembly ease of a storage battery unit, and a storage battery unit equipped with this connection structure.

An example connection structure of the present disclosure includes:
A connection structure for a storage battery unit comprising: a storage battery; a housing in which the storage battery is housed; and a control unit attached to the housing and controlling the storage battery, the housing having a first mounting surface to which the control unit is attached, and the control unit having a second mounting surface facing the first mounting surface when attached to the housing,
a first connection member provided on the first mounting surface of the housing;
a second connection member provided on the second mounting surface of the control unit and connectable to the first connection member;
Only one of the first connection member and the second connection member is supported by the housing or the control unit so as to be movable along the first mounting surface or the second mounting surface.

Moreover, the storage battery unit according to an example of the present disclosure includes:
The storage battery;
The housing in which the storage battery is accommodated;
a control unit attached to the housing and controlling the storage battery;
The connection structure connects the housing and the control unit.

According to the connection structure, only one of the first connection member and the second connection member is supported on the housing or the control unit so as to be movable along the first mounting surface or the second mounting surface. This configuration makes it easier to connect the first connection member and the second connection member compared to a connection structure in which both the first connection member and the second connection member are movable. As a result, a connection structure can be realized that can suppress a decrease in the ease of assembly of the storage battery unit.

The connection structure of the storage battery unit allows for a storage battery unit that is easy to assemble.

1 is a perspective view showing a storage battery unit including a connection structure according to an embodiment of the present disclosure. FIG. 2 is a perspective view showing the storage battery unit of FIG. 1 with a control unit removed; FIG. 2 is a schematic diagram showing a part of a cross section taken along line III-III in FIG. 1 .

An example of the present disclosure will be described below with reference to the attached drawings. In the following description, terms indicating specific directions or positions (e.g., terms including "up," "down," "right," and "left") will be used as necessary, but the use of these terms is intended to facilitate understanding of the present disclosure with reference to the drawings, and the meanings of these terms do not limit the technical scope of the present disclosure. In addition, the following description is essentially merely illustrative, and is not intended to limit the present disclosure, its applications, or its uses. Furthermore, the drawings are schematic, and the ratios of the dimensions do not necessarily correspond to reality.

As shown in FIG. 1, a storage battery unit 1 according to an embodiment of the present disclosure includes a storage battery 10, a housing 20 in which the storage battery 10 is housed, a control unit 30 that controls the storage battery 10, and a connection structure 50 that connects the housing 20 and the control unit 30. As an example, the storage battery 10 is composed of a plurality of cells. The control unit 30 is attached to one end of the main body 21 of each housing 20 in the longitudinal direction, which will be described later.

The storage battery unit 1 also includes a base 40 for fixing each storage battery device 2 together at an installation location. The base 40 is attached to the other end of the main body 21 of each housing 20 in the longitudinal direction of the main body 21.

In this embodiment, the storage battery unit 1 includes multiple storage battery devices 2, each of which is made up of one storage battery 10 and one housing 20. The storage battery devices 2 are integrated together in contact with each other.

As an example, as shown in FIG. 1, each housing 20 has a substantially rectangular parallelepiped main body 21 that houses the storage battery 10. As shown in FIG. 2, the main body 21 has a first mounting surface 22 provided at one end in the longitudinal direction thereof, to which the control unit 30 is attached. As an example, the first mounting surface 22 has a substantially rectangular shape when viewed along a direction intersecting the first mounting surface 22. A first connecting member 23 is provided on the first mounting surface 22. The first connecting member 23 is provided at one end in the longitudinal direction of the first mounting surface 22, and is connected to the storage battery 10.

As an example, the control unit 30 has a substantially rectangular parallelepiped shape as shown in FIG. 1. As shown in FIG. 2, the control unit 30 has a second mounting surface 31 that faces the first mounting surface 22 of each housing 20. A plurality of second connection members 32 are provided on the second mounting surface 22. Each second connection member 32 is provided at each of the opposing corners of the second mounting surface 31, and is configured to be connectable to each of the first connection members 23 of each housing 20 when the control unit 30 is attached to the housing 20. In other words, the storage battery 10 and the control unit 30 are connected via the first connection member 23 and the second connection member 32.

The connection structure 50 of the storage battery unit 1 includes a first connection member 23 of the housing 20 and a second connection member 32 of the control unit 30. As shown in FIG. 3, the first connection member 23 is supported movably along the first mounting surface 22 by a support plate 24 disposed inside the housing 20 and fixed to the housing 20. On the other hand, the second connection member 32 is supported by the control unit 30 so as not to be movable relative to the second mounting surface 31 of the control unit 30.

Specifically, the first connection member 23 is fixed to a substrate 25 having a plurality of substantially circular through holes 251. A substantially cylindrical protrusion 241 provided on the support plate 24 is accommodated inside the through hole 251. The protrusion 241 extends from the plate surface of the support plate 24 in the connection direction of the first connection member 23 and the second connection member 32 (for example, the vertical direction in FIG. 3). The protrusion 241 has a diameter smaller than the diameter of the through hole 251. That is, in the direction along the first mounting surface 22, a gap 51 is formed between the inner peripheral surface of the through hole 251 and the outer peripheral surface of the protrusion 241. The substrate 25 can move along the first mounting surface 22 together with the first connection member 23 within the range of the formed gap 51. A nut 242 and a washer 243 are attached to the tip of the protrusion 241. In addition, a roughly annular spacer 244 that adjusts the position of the nut 242 and washer 243 is disposed between the washer 243 on the protrusion 241 and the support plate 24.

3, the connection structure 50 of the storage battery unit 1 further includes a protrusion 26 provided on the first mounting surface 22 and a receiving portion 33 provided on the second mounting surface 31 and capable of accommodating the protrusion 26. The protrusion 26 extends from the first mounting surface 22 in the connection direction of the first connecting member 23 and the second connecting member 32. As an example, the receiving portion 33 is configured as a through hole that penetrates the member 34 that constitutes the second mounting surface 22 of the control unit 30. When connecting the first connecting member 23 and the second connecting member 32, the protrusion 26 is inserted into the receiving portion 33, so that the first connecting member 23 and the second connecting member 32 can be connected while determining the position between them.

In this embodiment, the housing 20 and the control unit 30 are fixed via a fastening member 35 such as a screw. Specifically, the mounting surface 22 of the housing 20 is provided with a fitting portion 27 into which the fastening member 35 fits, and the fastening member 35 is fitted into this fitting portion 27 to fix the control unit 30 to the mounting surface 22 of the housing 20.

The connection structure of the storage battery unit 1 provides the following advantages:

According to the connection structure, only the first connection member 23 is supported on the housing 20 so as to be movable along the first mounting surface 22. This configuration makes it easier to connect the first connection member 23 and the second connection member 32 compared to a connection structure in which both the first connection member 23 and the second connection member 32 are movable. As a result, a connection structure can be realized that can suppress a decrease in the ease of assembly of the storage battery unit 1.

The connection structure has a protrusion 26 on the first mounting surface 22 that extends from the first mounting surface 22 in a direction intersecting the first mounting surface 22, and a receiving portion 33 on the second mounting surface 31 that receives the protrusion 26 and determines the position between the first connecting member 23 and the second connecting member 32. This configuration makes it possible to reduce the machining precision required for the storage battery unit 1.

The connection structure further includes a fastening member 35 that fastens the housing 20 and the control unit 30. This configuration allows the housing 20 and the control unit 30 to be more securely connected.

The storage battery unit 1 can provide the following benefits:

The above connection structure allows for a storage battery unit 1 that is easy to assemble.

The connection structure of the storage battery unit 1 and the storage battery unit 1 can also be configured as follows:

This is not limited to the case where only the first connection member 23 is supported by the housing 20 so as to be movable along the first mounting surface 22. For example, only the second connection member 32 may be supported by the control unit 30 so as to be movable along the second mounting surface 31. In general, the storage battery device 2 is heavier than the control unit 30. For this reason, by having only the second connection member 32 movably supported by the control unit 30, it becomes easier to connect the first connection member 23 and the second connection member 32.

The protrusion 26 may be provided on the second mounting surface 31, and the receiving portion 33 may be provided on the first mounting surface 22.

The protrusion 26 and the receiving portion 33 can be omitted.

The fastening member 35 may be omitted. In other words, the control unit 30 does not have to be fixed to the housing 20. Alternatively, the control unit 30 may be fixed to the housing 20 using another structure.

The present disclosure is not limited to the storage battery unit 1, but can be applied to a storage battery unit including a storage battery 10, a housing 20 in which the storage battery 10 is housed, a control unit 30, and the connection structure.
