Between region outwardly projecting portion, the outwardly projecting portion have overhead the side plate intermediate region of the battery cell 10 be overhead plane 301, so
Setting can make the two sides intermediate region stress of 10 width direction of battery cell be greater than fringe region, to be conducive in partition 3
Extruding under preferably control the thickness deformation of battery cell 10, and make battery cell 10 edge will not because pressurize it is excessive
And it deforms, and then process requirements can be met.
Certainly, outwardly projecting portion in addition to it is above-mentioned have can overhead in the overhead plane 301 of battery side plate intermediate region, can also be
Arc surface 302 with overhead in battery side plate intermediate region, as shown in Figures 4 and 5, if in the side plate of battery cell 10
It is larger compared with the deflection of edge part in the middle part of side plate when larger, so set, the arc surface 302 may make 10 side plate of battery cell
Whole stress equalization, to be conducive to control the thickness of battery cell 10.
In addition, in order to play guiding role to sliding of the partition 3 in accommodating chamber, at least the one of 1 width direction of bottom plate
End, equipped with gib block 6 being extended along 1 length direction of bottom plate, being fixedly installed relative to bottom plate 1, gib block 6 and bottom plate 1
Between be formed with along 1 length direction of bottom plate extend, for partition 3 sliding insertion gap.Specifically, as shown in Figure 3 and Figure 5,
Guide groove 304 is formed in the both upper ends thereof of partition 3, in order to which gib block 6 above-mentioned slides in guide groove 304.Wherein, it is oriented to
The both ends of item 6 are respectively fixedly connected on two end plates 2, by the way that gib block 6 is arranged, so that partition 3 can slide in gib block 6, together
When so that the spacing between adjacent separator 3 is kept in balance unanimously, so as to effectively control the thickness of battery cell 10.
In addition, for the ease of accommodating the battery cell 10 of function, and each battery cell 10 is isolated respectively, in bottom plate
1 middle part is equipped with the isolation board 7 extended along the length direction of bottom plate 1, and accommodating chamber above-mentioned is divided into because of isolation board 7
Liang Ge sub-chamber being distributed along the width direction of bottom plate 1 and for accommodating each battery cell 10.Specifically, referring still to Fig. 3 and
Shown in Fig. 5, position is formed with groove 303 among the lower end of partition 3, to match with isolation board 7, so that partition
3 sliding on isolation board 7, and guiding role is played to the sliding of partition 3.
In the present embodiment, referring to shown in Fig. 1, in order to prevent when side bearing pressure is larger battery cell 10 end face
Deformation is equipped with the limited block 4 that overhead keeps accommodating chamber 20 in the opposite face of two neighboring partition 3 in each accommodating chamber 20.Its
In, the concrete shape of limited block 4 is the wide setting of thickness with battery cell 10, and with the high settings such as the height of battery cell 10
Rectangular block.In order to which the two sides further to 10 length direction of battery cell will not be deformed because of over-voltage, in the width along bottom plate 1
Degree direction, which is split, is provided with limited block 4 in 10 two sides of battery cell, is limited with the two sides to battery cell 10, thus just
In the thickness deformation amount of control battery cell 10.In addition to this, the restraining to battery cell 10 for the ease of holding tray body
Pressure is filled with resin plate 5 between end plate 2 and the partition 3 for closing on end plate 2.
Battery cell 10 at work, is placed on the accommodating chamber of tray main body by the power battery pallet of the present embodiment first

The two sides of slot 303 are provided with limited block 4, so that the two sides of battery cell 10 will not cross compressive strain.It is big by setting push rod thrust
It is small, the adjustable tray body contained pressure size initial to battery cell 10, in addition, being protected by the resin plate 5 of setting
Tray body is held to the contained pressure of battery cell 10.
Mechanism due to transmitting pressure between battery and battery is slidable partition 3, and the two sides of partition 3 are formed with outside
The outwardly projecting portion set with overhead in the central region of 10 side plate of battery cell is projected, which is about 1mm, is arranged such
So that extruding of the side of battery cell 10 by 3 outwardly projecting portion of two sides partition, centainly under contained pressure, so that the middle area of side
Domain stress is greater than fringe region, so that the thickness of battery cell 10 can be effectively controlled, and 10 edge of battery cell again will not be because
It pressurizes excessive and deforms.Since during 10 charge and discharge of battery cell, the contained pressure that 10 side of battery cell is subject to is whole
Body distributing equilibrium, therefore can be in the entire chemical conversion stage, effective control can be obtained in the thickness of battery cell 10.
In conclusion the power battery support holder structure of the utility model is simple, and manufacture easy to process, and can effectively control
Cell thickness of the brake force battery in chemical conversion stage charge and discharge process, to there is preferable practicability.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
