The specific embodiment of utility model is described in detail.
The utility model provides a kind of automobile, and with reference to Fig. 1, the part-structure of the vehicle body 20 of automobile, the car are shown in Fig. 1
Body 20 is located at spare tyre cabin.Blast pipe is provided with spare tyre cabin, the waste-gas heat of emission by exhaust pipe is higher, to prevent heat from passing through car
Body 20 is radiated to crew module's (not shown), with reference to shown in Fig. 2, and thermal insulation board 30 is additionally provided with vehicle body 20 of the present utility model, every
Hot plate 30 is aluminium or magnesium alloy thin plate.Along overall height direction (in Fig. 2 shown in X-direction), thermal insulation board 30 is located under vehicle body 20.Its
In, vehicle body 20 is provided with position relative with the first bolt hole on the first bolt hole (not shown), thermal insulation board 30 and is provided with
Second bolt hole 21.
In the present embodiment, vehicle body 20 is in " U " type shape, can be other shapes, such as tabular in other embodiments.Car
The left side and right side that body 20 is provided with multiple thermal insulation boards 30, figure are shown in which two thermal insulation boards 30.Wherein, Fig. 1 left side
Show that the second bolt hole on the second bolt hole 21 on thermal insulation board 30, the thermal insulation board 30 on Fig. 1 right side is covered by nut.The
It is used to pass through for bolt 40 after one bolt hole and the alignment laminating of the second bolt hole 21, and thermal insulation board 30 is fixed on by car by nut
On body 20.
During to avoid thermal insulation board 30 from being assembled on vehicle body 20, occurs craze and transfiguration in fixed point (i.e. at bolt hole).This
The nut of utility model is nut with elastic 10, referring to figs. 2 and 3 nut with elastic 10 includes：Nut body 11, nut body 11
Type be not limited, nut body 11 of the present utility model be hex nut, can be in other embodiments octagon nut,
12 jiaos of nuts etc..
Nut with elastic 10 also includes multiple elastic portions 12, and multiple circumferentially spaced circular nut bodies 11 of elastic portion 12 are set
Put, and surround through hole 12a (referring to Fig. 4).The quantity of elastic portion 12 is not limited, and eight elastic portions 12 are shown in Fig. 3.Nut
Axial one end of body 11 is at through hole 12a, the through hole 12a that multiple elastic portions 12 are surrounded and nut body 11 screwed hole
11a is connected.
With reference to shown in Fig. 1 and Fig. 2, multiple elastic portions 12 and the thermal insulation board 30 of nut with elastic 10 fit, and multiple elasticity
The through hole 12a that portion 12 is surrounded aligns with the second bolt hole 21 on thermal insulation board 30.Bolt 40 sequentially passes through nut body 11
Through hole 12a, the second bolt hole 21 and the first bolt hole that screwed hole 11a, multiple elastic portions 12 are surrounded, the nut of nut with elastic 10
Body 11 is set on bolt 40.Tighten nut body 11 so that thermal insulation board 30 is fixed on vehicle body 20.
It should be noted that, the vehicle body shown in Fig. 1 of the present utility model is located at spare tyre cabin, in other embodiments, can
Be located at enging cabin at vehicle body.As long as there is the position of thermal source on vehicle body, it can pass through shell fragment spiral shell of the present utility model
Thermal insulation board 30 is arranged on vehicle body 20 by mother 10, to prevent the heat of thermal source to be radiated to crew module through vehicle body 20.
During nut body 11 is tightened, the nut body 11 of carbon steel material can apply active force to thermal insulation board 30,
And cause thermal insulation board 30 in fixed point stress concentration.Due to circumferentially spaced circular 11 points of the nut body of multiple elastic portions 12
Cloth, then, each elastic portion 12 is separate, respectively will deform upon to discharge thermal insulation board 30 because by nut body 11 being applied
Active force and the stress produced, it is to avoid thermal insulation board 30 is concentrated and cracking failure in fixed point stress, so that thermal insulation board
30 excellent in durability.
If each elastic portion 12 is not separate, but it is connected with each other and is used as a complete entirety.When thermal insulation board 30 because
, can dorsad thermal insulation board as a complete overall elastic portion after the stress produced by the active force that nut body 11 is applied
Deform upon, but because elastic portion is overall deformation so that thermal insulation board can not discharge well in the stress concentration of fixed point.Phase
Instead, elastic portion can react on thermal insulation board in elastic force so that elastic portion is moved in the presence of elastic force by dorsad thermal insulation board
Switch to move towards thermal insulation board 30, accelerate the Cracking Failure of thermal insulation board.
Therefore, multiple spaced elastic portions 12 on nut of the present utility model can independent deformation, it is so favourable
The stress produced in release thermal insulation board 30 by the active force applied by nut body 11, the reduction craze and transfiguration of thermal insulation board 30
Risk.
