Embodiment
In order to clear, next it will be described with reference to rectangular coordinate system, wherein either in fore-and-aft direction still on a left side
In right direction, the side closer to origin O is inner side, is outside farther away from origin O side.
With reference to figure 1, the housing of power cell assembly 1 of pure electric sedan is used to arrange power electric in the bottom space of car
Pond.
With reference to figure 2, in the present embodiment, housing of power cell assembly 1 at least employs two pieces of bottom plates 9, two pieces of bottom plates 9 by
Waist longeron 3 and pallet 5 connect.When in the absence of waist longeron 3 and pallet 5, a monoblock bottom plate 9 can be also used.In this reality
Apply in example, waist longeron 3 is the box-like structure of sealing, can strengthen the structural strength of housing of power cell assembly 1.Waist longeron
3 upper surface is less than the upper surface of bottom plate 9, electrokinetic cell can be stored because of cooling and caused by condensed water, avoid condensed water pair
Battery damages.Pallet 5 overlaps in the front of waist longeron 3 and the upper surface of waist longeron 3, in pallet 5 and waist longeron 3
Lap position gluing sealing, waist longeron 3 upper surface storage cooling water can flow to pallet 5.Pallet 5 is used to carry wind
Evaporator is fanned, and structural strengthening effect is played together with waist longeron 3.There is opening, it is close that opening passes through rubber stopper on pallet 5
Envelope, when condensing dilutional hyponatremia caused by fan evaporator, rubber stopper can be extracted and discharged water, rubber is closed after the end that discharges water
Plug, it is simple and convenient, improve the insulating properties and security of electrokinetic cell.Polylith outside plate is fixed on bottom plate 9, and these outside plates include
Front beam outside plate 4, rear cross beam outside plate 8, left girder plate 2 and right vertical beam outside plate 7, they form electrokinetic cell at end to end surround
Receiving space.The common ground for the circuit that the equipotential support 6 connected on bottom plate 9 is used in housing of power cell assembly 1.
With reference to figure 3, the housing of power cell assembly 1 of pure electric sedan also includes the preceding horizontal stroke positioned at the rear of front beam outside plate 4
Beam liner plate 10, front beam liner plate 10 are monolithic construction, and intensity and precision are higher.Front beam liner plate 10 rises to front beam outside plate 4
Acted on to structural strengthening.
With reference to figure 4, the housing of power cell assembly 1 of pure electric sedan is located at the right vertical beam liner plate in the left side of right vertical beam outside plate 7
Reinforcing plate 11, it is therefore an objective to strengthen anti-collision energy, protect the safety of battery bag and the rigidity of vehicle body and intensity.
With reference to figure 5, Fig. 6, the housing of power cell assembly 1 of pure electric sedan also includes plug-in unit shield 12, plug-in unit shield 12
It is integrally located on front beam liner plate 10, the structure of plug-in unit shield 12 is simpler, faying surface is less, and gluing area is reduced, and increases
Strong housing seal.It is welded to connect after the outside gluing of plug-in unit shield 12 with front beam outside plate 10, and in the prior art in plug-in unit
The inner side gluing of shield 12 is compared, and the difficulty of the gluing mode of the present embodiment reduces, be advantageous to gluing uniformly with sealing.
With reference to figure 7, this Figure only shows the connection for the corner location being connected positioned at front beam outside plate 4 with right vertical beam outside plate 7
Part 13, in fact, in the pre-connection the corner location of crossbeam outside plate 4 and left girder plate 2, be connected rear cross beam outside plate 8 and left longeron
A connector 13 respectively be present in corner location, the corner location of connection rear cross beam outside plate 8 and right vertical beam outside plate 7 of outside plate 2.Connection
Part 13 is the transition piece between two neighboring outside plate, the upper surface of connector 13 and the adjacent outside plate that is connected with connector 13 it is upper
Surface is in same plane, so after upper shell is fastened upwards, will not produce gap, coated face will not also produce height up and down
Degree is poor, and sealing property accesses guarantee, and the upper surface for solving connector 13 and adjacent outside plate in the prior art is not put down same
So as to it is difficult to ensure that the problem of sealing, ensure that the security of electrokinetic cell in face.
Although the present invention is described with reference to above example, the present invention is not limited to above-described embodiment,
And only limited by claim, those of ordinary skill in the art easily can modify and change to it, but not from
The essential idea and scope of format invention.
