Hole 14.It should be understood that in the utility model embodiment, the battery pack 32 of electric vehicle be installed on twice sill strip 10 it
Between.
Collision of Flank Pole refers to that vehicle hits rigid post under certain travel speed, with certain collision angle, this
It collides under operating mode, the contact surface of rigid post and vehicle is relatively small, collides generated energy and is all absorbed by vehicle, to vehicle
Side part intrusion volume to be far longer than the intrusion volume under side collision operating mode, therefore it is also more tight to the degree of injury of vehicle
Weight.Battery will be also avoided as much as in addition to the occupant safety problem under Collision of Flank Pole operating mode to be considered for electric vehicle
Packet is hit, and as the security barriers of battery pack, the anti-invasion ability of sill strip is particularly important, and traditional sill strip exists
The shock of rigid post is easier to that localized crush occurs under squeezing, and to form localized hinge point in position of collision, loses and resists intrusion
The ability of load.
And the sill strip 10 for using this practicality new embodiment to provide, electric vehicle work as intrusion when by Collision of Flank Pole
When load destroys the outer guard of sill strip ontology 11 and then is applied to pipe beam 13, the pipe beam 13 with high transverse property is used as two
Secondary protective barrier can weaken the infiltration capability of intrusion load significantly；Meanwhile the intrusion load being applied on pipe beam 13 can pass
It is delivered on holder 12, and then entire sill strip 10 is transmitted to by holder 12, the concentration of local for being thus subject to sill strip 10 carries
Lotus decomposes 10 entirety of sill strip, to further reduce the infiltration capability of intrusion load.Therefore, compared with prior art, should
Scheme can greatly improve sill strip 10 under Collision of Flank Pole operating mode under the premise of not influencing 32 installation space of battery pack
Anti-invasion ability.

17 connect to form cavity structure with 18 pairing of sill strip inner panel, then the outer wall of sill strip inner panel 18 is just regarded as above-described embodiment
The bearing surface that the end of the sill strip ontology 11 being previously mentioned and floor crossmember 22 offsets.
Shown in Fig. 2 and Fig. 4, in the preferred embodiment of the utility model, the floor of holder 12 and electric vehicle
22 position of crossbeam is opposite, and when acting on the intrusion load on pipe beam 13 not less than intrusion load threshold value, intrusion load passes through branch
Frame 12 is transferred on floor crossmember 22.The concrete numerical value for invading load threshold value is unlimited, can be according to the complete vehicle structure of electric vehicle
It is determined.Using the example scheme, the intrusion load of holder 12 can will be transmitted to by pipe beam 13 further by holder 12
It is transmitted to the floor crossmember 22 with high intensity, is invaded to further improve anti-under Collision of Flank Pole operating mode of sill strip 10
Enter ability.
Shown in Fig. 2, in the preferred embodiment of the utility model, quantity and the floor crossmember 22 of holder 12
Quantity it is identical and holder 12 is arranged in a one-to-one correspondence with floor crossmember 22.Using the example scheme, invading for pipe beam 13 is acted on
Each floor crossmember 22 can be transmitted to by holder 12 by entering load, and this reduces the impacts suffered by each floor crossmember 22
Dynamics, to improve the fatigue life of floor crossmember 22.
Further, as shown in Figures 2 and 3, the quantity of pipe beam 13 is at least two, is provided on holder 12 and at least two
Pipe beam 13 passes through hole 14 correspondingly, and every pipe beam 13 is worn to penetrate passes through hole 14 in corresponding.The program is the intrusion in load
Direction increases at least one of protective barrier again, is invaded to further improve anti-under Collision of Flank Pole operating mode of sill strip 10
Enter ability.The particular number of Guan Liang is unlimited, can be specifically arranged according to the width of sill strip ontology 11, for example, new in this practicality
In the preferred embodiment of type, it is two to pass through the quantity in hole 14, i.e., is internally provided with two-tube girder construction in sill strip ontology 11, when
When pipe beam 13 far from 22 side of floor crossmember is not enough to resist intrusion load, another pipe beam 13 for being located at 13 inside of pipe beam can
To continue to play protective action.
The concrete structure of holder 12 is unlimited, as shown in Fig. 2, in the preferred embodiment of the utility model, holder 12 includes
It is arranged in parallel and along two side plates 15 that the extending direction of sill strip ontology 11 is arranged, and is connected between two side plates 15
