Detailed Description
The protective structure according to the present invention is used for mounting a weight object on a vehicle, and is suitably used for mounting a secondary battery called a battery pack, a battery module, or the like, a control unit for controlling the secondary battery, or the like, for example.
The structure itself may be a case made up of a plurality of plates, a frame made up of a plurality of frames, a structure made up of a combination of these, or the like, and the constituent members are not limited.
The protective structure according to the present invention is characterized by a connection structure of a side wall portion in the vertical direction and a horizontal portion in the lateral direction, which constitute a housing or a casing.
Fig. 1 (a) shows an example of a protective structure having a two-stage structure including a first mounting portion and a second mounting portion. The first mounting portion is constituted by a bottom plate 15, and the second mounting portion is constituted by a horizontal portion 12 provided above the first mounting portion and an intermediate plate 16 coupled to the horizontal portion as needed.
Vertical plates (11, 13, 14) are erected from a bottom plate 15 constituting the first mounting portion as side walls, and a horizontal portion 12 constituting the second mounting portion is connected to a side wall portion 11 in the center thereof, and an enlarged view thereof is shown in fig. 1 (b).
The side wall may be constituted by one plate-like side wall portion 11, but in the present embodiment, as shown in fig. 1 (a), 1 (b) and 2, it is formed in a three-divided structure, specifically, an upper side wall plate 14 is fitted and connected to a fitting flange-like connecting portion 11f formed at the upper portion of the side wall portion 11 located in the middle, and a lower side wall plate 13 erected from the bottom plate 15 is connected and fixed to a connecting flange portion 11g formed at the lower portion of the side wall portion 11.
The dividing structure and the connecting structure of the side wall are not limited.
The side walls may be provided on both sides of the first mounting portion and the second mounting portion so as to face each other, but in this embodiment, the bottom plate 15 and the intermediate plate 16 are connected by a plurality of side plates 17 (17 a, 17b, 17 c) each having a hollow cross-sectional shape.
Although not shown, the second mounting portion is formed in a structure in which the upper side of the second mounting portion is covered with a cover member fixed by an upper end flange portion 14a of the upper side wall plate 14.
The auxiliary flange portions 19a and 19b are provided at both side ends orthogonal to the side wall of the bottom plate 15, and the auxiliary flange portions 18a and 18b are provided at both side ends of the second mounting portion, if necessary, but these auxiliary flange portions may be omitted.
Fig. 1 (b) shows an enlarged partial view of the horizontal portion 12 and the side wall portion 11 in a state where the auxiliary flange portion 18b is removed.
The side wall 11 has a plate shape having a plurality of hollow portions 11c, 11d, 11e arranged in the vertical direction.
The hollow portion is formed in a shape connecting the centers of the inner rib 11b and the outer rib 11a by the connecting rib 11h, and a connecting portion with the horizontal portion 12 formed toward the inside of the protective structure and constituted by a hollow cross-sectional shape is formed as follows.
The horizontal portion 12 is formed with a plurality of horizontal hollow portions 12a by connecting the centers of a pair of upper ribs 12b and lower ribs 12c with a connecting rib 12d in the vertical direction.
The following state is changed: a part of the tip sides of the upper rib 12b and the lower rib 12c penetrates the inner rib 11b of the side wall portion 11.
In other words, the following state is changed: the hollow portion of the side wall portion is cut by the portions of the upper rib 12b and the lower rib 12c that penetrate, and the hollow portion 11c and the hollow portion 11d are formed. And, the following state is changed: the front end sides of the upper rib 12b and the lower rib 12c become outer ribs 11a, thereby forming horizontal hollow portions 12a.
Thus, when the secondary battery (battery module) V is mounted on the horizontal portion 12 forming the second mounting portion by a fixing pin or the like, not shown, the load is dispersed into a load f transmitted through the connecting corner portion of the upper rib 12b and the outer rib 11a 1 And a load f transmitted via the joint corner portion of the lower rib 12c and the inner rib 11b 2 。
This effect was compared with the connection structure shown in fig. 3.
Fig. 3 shows a case where the horizontal portion 112 having a hollow cross-sectional shape and the side wall portion 111 having a hollow portion in the up-down direction are connected at substantially right angles.
When such a connection structure is formed, the load applied to the horizontal portion 112 is liable to concentrate stress on the corner portion f 0 So that the local load to the portion becomes large.
In contrast, in the connection structure according to the present invention, the stress is dispersed to f 1 And f 2 Therefore, the present invention has a dispersing effect even against a load from the outside such as an impact, and therefore has a high protection effect on the mounted object.
In addition, vibration generated during traveling is also dispersed into f 1 And f 2 And transmitted to the side wall 11, the vibration durability is also excellent.
Such a connection structure can be easily manufactured by an extrusion material such as an aluminum alloy.
