Property is high, can repeatedly dismantle, recycles.
The structure of this connected mode is simple, low cost, can reduce assembly difficulty, simplifies assembly process.Furthermore, nut with
Bolt cost is relatively low, connects reliable, is conveniently replaceable.
Wherein, according to an embodiment of the present utility model, fixture 14 is respectively steel materials and parts with fixed plate 13, installs
Plate 114 is aluminium materials and parts.The structural strength of the fixture 14 made with steel due to the installing plate 114 that aluminum is made, rigidity
Difference, if fixture 14 is directly arranged in cavity 1141 being connected with securing member, makes fixture 14 directly connect with installing plate 114
Touch, because fixture 14 is less with the contact area of installing plate 114, and the intensity of the intensity opposed fixed member 14 of installing plate 114
Poor, so can accelerate the damage of installing plate 114.
The electrokinetic cell 100 of the utility model embodiment, the fixture 14 made by Steel material is arranged on fixed plate 13
On, so that the fixed plate 13 being provided with fixture 14 is directly contacted with installing plate 114, both can facilitate fixture 14 and installing plate 114
Connection, thus lid 12 is connected it is ensured that the connection reliability of upper lid 12 and lower box 11 with lower box 11 on convenient, again can be by
Securing member is disperseed with the fastening force of fixture 14, it is to avoid the position being connected with fixture 14 of installing plate 114 is damaged, significantly
Improve the structural strength of lower box 11.
According to the automobile (not shown) of the utility model second aspect embodiment, including the power electric according to above-described embodiment
Pond 100.Because the electrokinetic cell 100 according to the utility model above-described embodiment has above-mentioned technique effect, therefore, according to this reality
With the automobile of new embodiment, also there is corresponding technique effect, that is, the structure of this automobile is simple, each part connects reliable, assembly and disassembly
Convenient, assembly process is simple, lighter in weight, and insulation safety is higher, Stability Analysis of Structures, can effectively stop single battery core 32
Thermal failure impact, long service life.
