Description
Technical field
The utility model relates to the technical field of automobile power battery system structural member, especially a kind of power battery is high
Strength joint construction component, the connection of bottom, side for battery and shell, in particular to its mechanical connecting structure.
Background technique
As the problems such as energy shortage, environmental pollution gets worse, country has formulated the new-energy automobiles such as electric car hair
Exhibition strategy.This makes more and more electric cars enter market.Electric car in the process of moving and occur traffic accident when,
Its reliability and safety are concerned.Electrokinetic cell system is most crucial one of component, at the same also when safe design most see
The link of weight.
Currently, many electronic logistic cars are to be arranged repacking on traditional logistics chassis, battery pack usually cloth
It is placed in central frame beam.Space is abundant in battery pack short transverse, horizontal and vertical space relative deficiency.So that battery modules in wrapping
There is two layers of case for stacking installation.And two layers of mould group stacks, battery entirety center of gravity is higher, and the fixed stay bolt of mould group is vibrated in Z-direction
When, it can be by stronger shear stress close to the fixed stay bolt of the mould group of whole packet installation point, there are risk of breakage.
Utility model content
The purpose of this utility model is to provide a kind of power battery high-strength connection structure components, are arranged in upper and lower level
On mould group middle spacer, mould group and housing sidewall are connected.To enhance the strength and stiffness of battery pack structure system.It ultimately helps
Meet national compulsory check test standard and vehicle endurance test standard.
To achieve the goals above, a kind of the technical solution of the utility model are as follows: power battery high-strength connection structure
Component, the component include that connection cushion block, cantilever, internal and external threads sleeve, bolt and welded nut, cantilever laterally form nut
Fitting groove, above-mentioned welded nut are embedded in above-mentioned nut fitting groove, and welded nut is fixed on nut fitting groove by welding manner
It is interior, through-hole is offered at cantilever vertically downward, which opens up that position is corresponding with welded nut, and the one end for connecting cushion block is vertical
Threaded hole is offered downwards, and internal and external threads sleeve screws in above-mentioned threaded hole, and bolt screws in internal and external threads sleeve, passes through still further below
After reach through hole screw in welded nut in, bolt external screw thread engage with the internal screw thread of connected nut, the external screw thread of internal and external threads sleeve and
The internal screw thread of threaded hole engages.
The utility model discloses a kind of power battery high-strength connection structure components, are conducive to power battery pack housing
The connection of interior battery modules and housing bottom, side arm face is fixed its role is to increase connection cushion block stress point with reducing mould group
Shear stress suffered by stay bolt increases the strength and stiffness of structural system.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model installation diagram.
Fig. 3 is the utility model use state system installation diagram.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
The utility model discloses a kind of power battery high-strength connection structure components to be different from as shown in fig. 1
The prior art is: the component includes connection cushion block 1, cantilever 2, internal and external threads sleeve 3, bolt 4 and welded nut 8, is hanged
2 side of arm is embedded in above-mentioned nut fitting groove 5 to nut fitting groove 5, above-mentioned welded nut 8 is formed, and welded nut 8 passes through welding side
Formula is fixed in nut fitting groove 5, offers through-hole 6 at cantilever 2 vertically downward, which opens up position and welded nut 8
Corresponding, one end of connection cushion block 1 offers threaded hole 7 vertically downward, and internal and external threads sleeve 3 screws in above-mentioned threaded hole 7, bolt
4 screw in internal and external threads sleeve 3, screw in welded nut 8 after through-hole 6 still further below, 4 external screw thread of bolt and connected nut 8
Internal screw thread engagement, the external screw thread of internal and external threads sleeve 3 are engaged with the internal screw thread of threaded hole 7.3 bottom end of internal and external threads sleeve and cantilever
Top tap touching, can be filled the two gap.
In the specific implementation, the inner and outer wall of internal and external threads sleeve 3 is respectively formed screw thread, and 3 bottom of internal and external threads sleeve
Sectional area be greater than the sectional area at the top of it, approximate internal and external threads sleeve 3 is in circular cone shape, and bottom larger area resists cantilever 2
Top can be filled connection cushion block 1 and the gap between the two of cantilever 2, and facilitate improving stability.
In the specific implementation, bolt passes through connection cushion block, screws in welded nut in cantilever hole, is attached thereto, while bolt
Flange face compresses connection cushion block.
In the specific implementation, as shown in Figure 2, the main body approximation of cantilever 2 is in channel steel structure, and notch is distributed outward, slot
The upper limb and lower edge of mouth are upward, are formed down overhead gage 9 and lower baffle plate 10, which is above-mentioned nut fitting groove 5, connection
