Abstract
The utility model discloses a shock -absorbing structure of battery box, it includes a box and lid, the box includes the bottom plate and encloses the curb plate of locating around the bottom plate, the box is used for acceping ganged group battery, the battery pack forms by the PCB board is parallelly connected in groups, correspond PCB board position department on the box bottom plate and be equipped with rubber non -slip mat, accommodate behind the box when group battery in groups, distolateral butt a to rubber non -slip mat of PCB board. Compared with the prior art, the utility model discloses shock -absorbing structure of battery box adopts the rubber non -slip mat that is equipped with the U -shaped groove, avoided PCB stiff and straight connect with the steel sheet or the epoxy plate contact of battery box, even produce certain vibrations when the electric motor car move, can not lead to group battery and box to produce too big relative displacement yet, the electric core of having avoided battery cell contacts with the box and produces unsafe factor.
Description
[technical field]
The utility model relates to new energy electric motor vehicle technical field, specifically refers to a kind of shock-damping structure of battery case.
[background technology]
Along with each big city vigorously advocating energy-saving and emission-reduction, Green Travel becomes a lot of civic preferred manner, and under this overall situation, the popularity rate of electric motor car is also more and more higher.The voltage of cell and electricity are all very limited, Given this, be widely used in electric motor car by multiple cell by the battery pack that connection in series-parallel is combined to form, these battery pack are often placed in the power subsystem forming electric motor car in a casing together with BMS control system, i.e. battery case.
Battery case is arranged on car body usually, and in car running, battery case can produce with car body and resonate, and this can cause colliding between battery pack and casing in casing and causing security incident to occur.This is mainly because there is wretched insufficiency in existing battery case structural design.In existing battery case, epoxy plate is positioned over the dividing plate of bottom half as battery pack and iron case.The steel plate of battery case casing contacts with epoxy plate directly, and the hardness of this bi-material is higher, and frictional resistance is less, very little vibrations will produce relative displacement, this long-term relative displacement, can cause worn out epoxy plate gradually, finally causes the battery core of cell to contact with casing the phenomenon that is short-circuited.
Sign in more than, be in fact necessary to provide a kind of shock-damping structure that can overcome the battery case of defect of the prior art.
[utility model content]
The purpose of this utility model is to provide a kind of simplicity of design, the shock-damping structure of the battery case of low cost of manufacture.
To achieve these goals, the utility model provides a kind of shock-damping structure of battery case, it comprises a casing and lid, described casing comprises base plate and is located in the side plate of base plate surrounding, described casing is for accommodating battery pack in groups, and described stack battery group is formed in parallel by pcb board, and on described box bottom, corresponding pcb board position is provided with rubber antiskid pad, after stack battery group is contained in casing, the end side of described pcb board abuts to rubber antiskid pad.
One as the shock-damping structure of the utility model battery case is improved, and described rubber antiskid pad is provided with U-lag, and pcb board is installed in U-lag.
One as the shock-damping structure of the utility model battery case is improved, and be also equipped with collision mat between described casing and lid, described collision mat is sealed to box opening.
One as the shock-damping structure of the utility model battery case is improved, and described lid fastens and locks with screw to casing.
Compared with prior art, the shock-damping structure of the utility model battery case adopts the rubber antiskid pad being provided with U-lag, avoid pcb board directly to contact with the steel plate of battery case or epoxy plate, even if produce certain vibrations when electric motor car runs, also battery pack and casing can not be caused to produce excessive relative displacement, and the battery core avoiding cell contacts with casing and produces unsafe factor.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of the shock-damping structure of the utility model battery case.
Fig. 2 is the enlarged drawing of part A in Fig. 1.
[embodiment]
In order to make, the purpose of this utility model, technical scheme and Advantageous Effects are more clear to be understood, below in conjunction with the drawings and specific embodiments, is further elaborated to the utility model.Should be understood that, the embodiment described in this specification is only used to explain the utility model, is not to limit the utility model.
Please refer to shown in Fig. 1, the utility model provides a kind of shock-damping structure 100 of battery case, it comprises a casing 10 and lid 20, described casing 10 comprises base plate 11 and is located in the side plate 12 of base plate surrounding, described casing 10 is for accommodating battery pack 30 in groups, described stack battery group is formed in parallel by pcb board 40, on described box bottom 11, corresponding pcb board 40 position is provided with rubber antiskid pad 50, after stack battery group is contained in casing, the end side of described pcb board 40 abuts to rubber antiskid pad 50.
Specifically, the form of the composition of the pattern by the series and parallel connections matrix of each cell in stack battery group, pcb board wherein serves as medium in parallel.Rubber antiskid pad 50 rectangular-blocklike, the surface contacted with pcb board is provided with some U-lags 51, and during assembling, the end side of aforesaid pcb board 40 is inserted in U-lag 51.
The one of the shock-damping structure of the utility model battery case is improved, and be also equipped with collision mat between described casing and lid, described collision mat is sealed to box opening, in order to by lid and tighter the combining of casing, usually can fasten to casing at lid.Lock with screw again.
The shock-damping structure of the utility model battery case, be not restricted to described in specification and execution mode, therefore additional advantage and amendment can easily be realized for the personnel of familiar field, therefore when not deviating from the spirit and scope of the universal that claim and equivalency range limit, the utility model is not limited to specific details, representational equipment and illustrates here and the examples shown described.
