Description
Technical field
The present invention relates to electric automobile field, more particularly, to a kind of electrokinetic cell bag.
Background technology
Present Global auto industry is faced with the huge challenge of energy and environment problem；Capacity usage ratio is high, to environment no
The pure electric automobile of pollution is increasingly becoming the direction of future automobile industrial development.When China is in the energy conversion of vehicle at present
Phase, new energy vehicle currently increasingly increases, in each large enterprises, as the battery modules in new energy vehicle, power electric
The production efficiency of Chi Bao improves, and determines the height of its productivity effect, and in existing electrokinetic cell bag, be mostly two-layer or
Three layers of person, every layer is all provided with BMU (battery management unit) in casing, when need install or maintenance BMU when, especially in
Lower two-layer, due to pulling down whole casing, row pulls down BMU again, it will bother very much, existing mode is by every layer of casing front end
Specially it is provided with BMU gateway, installing plate is installed at gateway, this gateway is covered, meanwhile, BMU is arranged on installing plate
BMU thus can be placed and taken out from this gateway by inner side with the dismounting of installing plate, but current BMU is arranged on case
The fixed form of body uses four bolts and is fixed on installing plate, then with four bolts, installing plate is fixed on outside casing
Side, when needing BMU is overhauled, simply needs to dismantle 8 bolts and BMU could be taken out, same during installation, needs tight
Gu 8 bolts, although this mode has made moderate progress to the raising of productivity ratio, the bolt due to needing fastening is more,
So still comparatively laborious, installation, removal efficiency be not high, still becomes a problem of impact productivity ratio.In addition, traditional peace
In dress mode, because installing plate have left casing after dismounting lower installation board, when being installed again, need the screw of installing plate
Position is found accurately with the position of mounting hole on casing, due to installing plate is relatively thin and its inside already installed with BMU, so having certain
Weight, cause operating personnel to be not easy to hold it is difficult to align mounting hole site, also create the problem of inefficiency, impact life
Produce.
Content of the invention
For solving above-mentioned technical problem, the invention provides a kind of electrokinetic cell bag, the BMU in this electrokinetic cell bag is in peace
It is not required to during assembly and disassembly fasten or dismantles excessive bolt, production efficiency can be greatly improved, and structure is simple, easily
Operation,.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of electrokinetic cell bag, including casing and BMU, with
Unlike prior art, also include installing plate；Described casing one side offers gateway, and described installing plate is installed on described
The outside of casing, and described gateway is covered；Described installing plate one end is hinged with described casing, and the other end and described casing can
The connection of dismounting；The inner side of described installing plate is provided with sliding seat, and described sliding seat offers chute, and described BMU both sides are provided with L
Shape gripper shoe, described BMU can be slipped into from one end of described chute by described L-shaped gripper shoe；Described BMU can be with described installing plate
Be rotated into or pass described gateway.
The invention has the beneficial effects as follows, BMU can enter line slip in the sliding seat inside installing plate, and installing plate passes through
One section of hinged mode in dismountable connection one end is fixed on outside casing and seals gateway, in this manner it is possible to install
When first the detachable end of installing plate is taken apart, using the rotation connected mode of hinged place, it is suitable that installing plate is carried out turning to
Angle, BMU is slipped into into along the chute of sliding seat, and chute not only can play guide effect, and can play fixation
The effect of BMU, after BMU is completely into chute, installing plate is rotated to casing direction, is fixed in casing；When need
When dismantling BMU, carry out in the opposite order operating.Electrokinetic cell bag provided by the present invention, is installing to BMU
When, can be not required to excessive bolt is operated, substantially increase operating efficiency, meanwhile, installing plate can also be protected in dismounting
Hold one end hinged, so when installing BMU or dismounting BMU, installing plate is still remained connected to casing, and its relative position is not
Become, then during the fastening of row bolt, only need to overturn and fit with casing, mounting hole site is nature be aligned, is not required to operating personnel and goes
Device to hole, substantially increases operating efficiency.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the lower end of described installing plate is hinged with described casing, and described installing plate can overturn before and after hinged place.
Beneficial effect using above-mentioned further technical scheme is to carry out the lower end of installing plate and casing hinged, and
So that installing plate can be overturn before and after hinged place, so can facilitate operating personnel that BMU is carried out with insertion and the taking-up of above-below direction.
Further, the lower end of described installing plate is fixedly connected with bearing pin, and described casing is fixedly connected with pin-and-hole
