To prevent battery modules 10 from contacting with vertical plate part 222, when vibrating at battery pack 100, battery modules 10 are preferentially only against long limb
On 422, absorbed by pressure of the long limb 422 to battery modules 10 to reduce the risk of damage battery modules 10, to battery mould
Group 10 plays a good protective effect.
As shown in figure 3, the upper end of long limb 422 has guiding inserting surface in the utility model further embodiment
4221, guiding inserting surface 4221 has good booster action to the installation of battery modules 10.
It is understood that needing that first supporting pad 40 is fixed on crossbeam 22, supporting pad in assembled battery packet 100
40 with crossbeam 22 close fit, heat exchanger plates 30 are arranged on supporting pad 40 later, guiding inserting surface 4221 exchanges hot plate 30
Installation has guiding role, in order to which heat exchanger plates 30 are pressed on the support portion 41 of supporting pad 40.When installing battery modules 10,
Battery modules 10 are put into the region between two crossbeams 22, since the space between two crossbeams 22 is greater than battery modules
10, position of the battery modules 10 between two crossbeams 22 is not fixed, and is not easy to battery modules 10 and 22 secure fit of crossbeam, is led to
It crosses guiding inserting surface 4221 and reduces scope of activities of the battery modules 10 between two crossbeams 22, in order to which operator is to battery
Mould group 10 is assembled.
In some embodiments of the utility model, the material of supporting pad 40 can be in rubber, plastics and foam etc.
At least one.Thus supporting pad 40 has certain deformability, when supporting pad 40 receives the pressure of the application of heat exchanger plates 30, branch
Stake pad 40 will generate a certain amount of deformation, when installing battery modules 10, tolerance can be absorbed by supporting pad 40, to be promoted
The assembly effect of battery modules 10.
It should be noted that deformation occurs for supporting pad 40, simultaneously when the pressure that supporting pad 40 is applied by heat exchanger plates 30
It feeds back to heat exchanger plates 30 to upward pressure, so that the cooperation between heat exchanger plates 30 and heat-conducting plate 50 is more preferable, promotes heat transference efficiency,
But the pressure that supporting pad 40 feeds back to heat exchanger plates 30 should not be too large, and need to realize that supporting pad 40 absorbs the flat of tolerance and bounce
Otherwise weighing apparatus has an impact the structure for exchanging hot plate 30, the application proposes the structure of a variety of supporting pads 40 thus, following multiple realities
Example is applied, however, it is not limited to this.
In some embodiments of the utility model, support portion 41 includes: support bar and support bar upper surface is arranged in
Multiple protrusions spaced apart.Since multiple protrusions are spaced arrangement, so as to reduce supporting pad 40 and heat exchange
Contact area between plate 30 is (compared to the upper surface of support portion 41 and the way of contact contact area of 30 Full connected of heat exchanger plates
It is small), reasonably to reduce the bounce of supporting pad 40, and then realize the balance for absorbing tolerance and bounce.
In some embodiments of the utility model, support portion 41 is configured to bar shaped, and support portion 41 is towards close to even
The direction of socket part 42 is in tilted layout.It is understood that when heat exchanger plates 30 apply downward pressure to support portion 41, support portion
41, which first will bend deformation towards 42 one end of interconnecting piece, reduces bounce, to realize the balance for absorbing tolerance and bounce.
In some embodiments of the utility model, support portion 41 is configured to bar shaped and has hollow cavity.Work as heat exchanger plates
When 30 pairs of support portions 41 apply downward pressure, deformation can be bent at the cavity of support portion 41 to reduce bounce, to realize
Absorb tolerance and rebound dynamic balance.
In some embodiments of the utility model, crossbeam 22 and bottom wall 21 are preferably aluminium, so as to guarantee shell
Under the premise of 20 structural strength of body, the weight of shell 20 is reduced, reasonably to realize the light-weight design of battery pack 100.
In some embodiments of the utility model, heat-conducting plate 50 is acrylic acid cushion, and heat-conducting plate 50 can play absorption
The effect of tolerance, and can by the heat transfer of battery modules 10 to heat exchanger plates 30, since heat conductive pad is acrylic acid cushion,
The matching of heat conductive pad and heat exchanger plates 30 is more preferable in battery pack 100, can promote the heat transmitting between heat conductive pad and heat exchanger plates 30
Efficiency.
Referring to Fig.1, in some embodiments of the utility model, battery pack 100 further include: water pipe 60, water pipe 60 are suitable for
It is connected to across multiple crossbeams 22 and with the external of battery pack 100, to provide coolant liquid to heat exchanger plates 30 by water pipe 60.
In some optional embodiments of the utility model, multiple battery modules 10 in battery pack 100 are arranged symmetrically
In the two sides of water pipe 60, and the high pressure socket of battery modules 10 and low pressure socket be towards 60 side of water pipe, thus in battery pack
100 occur have high security when external impact.
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
