Summary of the invention
(technical problems to be solved by the inivention)
The purpose of the present invention is to provide a kind of impact absorbing members big for the protecting effect from external impact
And the impact absorbing structure body using the impact absorbing member.
(for solving the technological means of technical problem)
Impact absorbing member according to the present invention is the impact absorbing member for being installed on the end of basic components, institute
It states impact absorbing member and is characterized by having hollow portion, longitudinal wall part and diagonal rib, the hollow portion and the basic components are along water
Square to configuration, the longitudinal wall part is configured at the one side or both of the up and down direction of the hollow portion, and the diagonal rib will be described
Hollow portion and the longitudinal wall part are connected obliquely.
Here, so-called basic components refer to, for the power supply units such as battery component and high voltage part etc. to be installed on vehicle
Component.
There is no restriction for mounting structure, is not only also to be loaded into the method that the mode on basic components is carried
Enough it in a manner of hanging on downside should carry out that various modes are installed etc..
In addition, in the present invention, the longitudinal wall part of the one side or both of the so-called up and down direction for being configured at hollow portion can
With from the installation base portion side of the basic components of hollow portion perhaps hollow portion front end side further from the upper surface of hollow portion or under
The midway in face erects upward, can also hang down downward, or aforementioned two kinds of setting.
In the present invention, it is preferred that hollow portion has a pair of up and down of the end for being installed on the basic components
Flange part.
In this case, can be linked in a manner of being inserted into the end of basic components between lower a pair of of flange part upwards.
Impact absorbing member according to the present invention can be towards wanting to be protected from from being applied to rushing for basic components
The position and direction hit are installed, and the shape and construction of basic components are without limitation.
For example, being capable of forming as above-mentioned impact absorbing member to be installed on to the impact absorbing of the end of the two sides of basic components
Tectosome.
In this case, in basic components, if the opposite direction with the impact absorbing member of the two sides is orthogonal
Direction section be hollow sectional shape if, then the impact absorbing protecting effect of basic components is also got higher.
(The effect of invention)
The details of the impact absorbing deformation of impact absorbing member according to the present invention are aftermentioned, for coming towards basic components
From the impact of horizontal direction, hollow portion plays a role as beam.
For example, in such a way that diagonal rib connects the longitudinal wall for being erected on top with hollow portion the example that links into
Row explanation, the impact for being applied to hollow portion obliquely from above are absorbed in such a way that diagonal rib stretches, are tilted from the downside of hollow portion
The impact that ground applies is absorbed in a manner of diagonal rib bearing, and as a result, regardless of the application direction impacted, protecting effect is all high.
In addition, details are aftermentioned.

Specific embodiment
Based on the following drawings to the structure example of impact absorbing member according to the present invention and impact absorbing structure body into
Row explanation.
Fig. 1 (a) and Fig. 1 (b), Fig. 2 (a) and Fig. 2 (b) show embodiment 1.
Embodiment 1 is to link the example of impact absorbing member 20 in the end of the two sides of basic components 10.
Basic components 10 are used for battery-mounted component and high voltage part.
In the present embodiment, basic components 10 are formed as plate, but may be frame-like, and there is no restriction for construction.
Basic components 10 are the side of top panel 11 and lower panel 12 by the connection of longitudinal rib 13a, 13b, during central portion passes through
Between rib 13c link hollow sectional shape example, the side of two sides is provided with the fixed part 15 for being fixed on vehicle, and
And fixation hole 15a is provided on the fixed part 15.
Impact absorbing member 20 can be rushed according to wishing to absorb from external relative to the installation site of basic components 10
The direction hit is installed, for example, a pair of of impact absorbing member 20,20 is located at vehicle when basic components 10 are installed on vehicle
Front side and rear side.
Alternatively, it is also possible to be only install an impact absorbing member mode.
Impact absorbing member 20 has the hollow portion 21 of the horizontal direction positioned at basic components 10 and connects with the hollow portion 21
Longitudinal wall part 22, the longitudinal wall part of lower side 23 of the upper side of knot.
The longitudinal wall part 22 of upper side has the diagonal rib 24 linked in a manner of tilting connection with hollow portion 21.
The longitudinal wall part 23 to hang down to the lower side has the diagonal rib 25 with the inclination connection of hollow portion 21.
The present embodiment is the example for linking the front end of longitudinal wall part 22,23 and the front end side of hollow portion 21 by diagonal rib 24,25
For son but it is also possible to be the diagonal rib linked in the midway of longitudinal wall part, hollow portion, the connection type of diagonal rib can be along inclined direction
Configuration.
Further, as shown in Fig. 3 (c), or following construction: the longitudinal wall part 28 of the front end side of setting hollow portion 21,
Diagonal rib 24a, 25a are set with Fig. 2 (a) and Fig. 2 (b) opposite direction.
Hollow portion 21 is by the horizontal ribs a pair of of up and down towards compression zone 21a, horizontal direction from external impact
21b, 21c and be connected to basic components 10 end face transfer part 21d constitute hollow sectional shape beam.
In addition, forming following construction: a pair of flanges portion 26a, 26b up and down are extended to form from the transfer part 21d of hollow portion 21,
Insertion connection is carried out in a manner of clamping the end of basic components 10 by the flange part 26a, 26b.
As a result, as shown in Fig. 2 (b), it is applied to the impact f of compression zone 21a1Basic components are transferred to via hollow portion 21
10。
In addition, as shown in Fig. 3 (a), the impact f from oblique upper2Hollow portion 21 is set to generate curved deformation force downwards
D, but due to drawing force S act on upside diagonal rib 24 and compressing force P act on downside diagonal rib 25, it is suppressed that it is hollow
The deformation in portion 21, impact force are easy to be transferred to basic components.
In contrast, as shown in Fig. 3 (b), if applying impact from direction compression zone 21a obliquely downward, compressing force P makees
Diagonal rib 24 and drawing force S for upside act on the diagonal rib 25 of downside, and impact force is equally transferred to basic components.
As shown in Fig. 3 (c), even if forming longitudinal wall part 28 in compression-side, and make the link direction phase of diagonal rib 24a, 25a
Instead, identical effect can also be generated.
As shown in Fig. 4 (a), Fig. 4 (b) and Fig. 4 (c), even if only the single side of side or the setting of the single side of downside are vertical above
Wall portion 22 can also generate metamorphosis as described above.
In this case, relative to the impact force f from oblique upper2, the receiving drawing force S of diagonal rib 24, and for coming from
The impact force f of obliquely downward3, compressing force P generation effect.
In addition, as shown in Fig. 5 (a), Fig. 5 (b) and Fig. 5 (c), even if forming horizontal ribs between longitudinal wall part 22 and diagonal rib 24
27, it can also generate identical effect.
Fig. 6 is shown as the example with reference to the case where diagonal rib may be not present.
Even if having hollow portion 121, and longitudinal wall part is set in hollow portion 122,123, if without diagonal rib, only
Pass through the d upwards of hollow portion 1211Or lower section d2Bending deformation is generated, impact force can not fully be transferred to basic courses department
Part.
