Description
Technical field
The utility model belongs to auto Body Technology field, and in particular to a kind of connection knot of Battery case and battery modules
Structure.
Background technique
New-energy automobile is generally using the battery modules being made of lithium ion battery as power source.For integrated and protection electricity
Battery modules, are usually mounted in Battery case by Chi Mo group, and the connection type of existing Battery case and battery modules is general are as follows:
Plate is welded and fixed on clamping plate before and after the battery modules, then fixed plate is fixed on to the horizontal support surface of the fixed plate of Battery case
On.Since the contact surface of battery modules and Battery case is small, while battery modules quality is larger, is easy in vehicle travel process
Occur battery modules offset and collision, cause battery modules electrical property, in terms of stability and protective
Decline.
China's Patent Application Publication (publication No.: CN107768575A；The day for announcing: 2018.03.06) in disclose one kind
Battery case structure on power vehicle, including Battery case and it is set to the intracorporal battery modules of battery case, limit
Fixation kit and stretching snap component, the technical solution are limited the double swerve of battery modules by limit fixation kit, passed through
It stretches snap component and limits the moveable range of Battery case.
Although above-mentioned technical proposal improves battery modules in the intracorporal anti seismic efficiency of battery case, also to a certain extent
It has the following problems: in vehicle traveling process, when special rough ride, since battery modules periphery is mutually fixed with Battery case,
Therefore the vertical tremor of battery modules is more obvious, which, which uses, stretches snap component (specially draw springs),
When sharp impacts occur for Battery case, battery modules are stretched to limit the moving range of battery modules, however due to tensile elasticity
Part itself is easy to be stretched, therefore this mode is relatively limited for the vibration of buffer battery mould group, while when battery modules are sent out
After raw offset, automatically resets substantially by self gravity, be easy to happen secondary collision and damage.
Summary of the invention
The utility model aiming at the above problems existing in the prior art, provides the company of a kind of Battery case and battery modules
Binding structure, the technical problem to be solved by the utility model is to how buffer battery mould group is in the intracorporal vertical tremor of battery case.
The purpose of this utility model can be realized by the following technical scheme:
A kind of connection structure of Battery case and battery modules, the side wall of battery modules are erected in the bottom of the Battery case
On plate, which is characterized in that the connection structure includes an at least block pressur plate, and the lower end of the pressing plate is fixedly connected with the bottom plate,
The upper end of the pressing plate is equipped with one-way wheel, and the upper end of the pressing plate is described with making to the elastically-deformable trend in side wall side
One-way wheel is pressed against on the side wall, and the one-way wheel is only capable of scrolling up relative to the side wall.
By the pressing plate being installed on Battery case bottom plate, one-way wheel is set in pressing plate upper end, and pressing plate upper end have to
The elastically-deformable trend in side wall side, therefore one-way wheel can be securely pressed against on the side wall of battery modules.One-way wheel is only capable of
Opposing sidewalls scroll up, and when vibration, which occurs, for battery modules offsets up, one-way wheel is unable to opposing sidewalls and scrolls down through, i.e., singly
It is in self-locking state to wheel, side wall is offset up to form larger resistance, it can the effectively vibration that is upwardly deviated from of buffer battery mould group；
When resetting under Gravitative Loads after battery modules are upwardly deviated from, one-way wheel energy opposing sidewalls scroll up, at this time side wall
Needing to overcome the frictional force between one-way wheel and side wall in reseting procedure, thus can buffer battery mould group when resetting vibration (
The downward vibration of battery modules), battery modules are improved in the intracorporal shock resistance of battery case.
In the connection structure of above-mentioned Battery case and battery modules, the upper end of the pressing plate is equipped with mounting rack, described
One-way wheel is rotationally connected on the mounting rack.Mounting rack is conducive to improve the installation stability of one-way wheel, ensures that one-way wheel is tight
Admittedly be pressed against on side wall, to ensure one-way wheel to the buffer function of battery modules vertical tremor.
In the connection structure of above-mentioned Battery case and battery modules, the quantity of the one-way wheel on the mounting rack
It is 6-12, and the one-way wheel is arranged in array.Single multiple one-way wheels in array arrangement can be improved one-way wheel with side wall it
Between frictional force, be conducive to buffer battery mould group in the intracorporal vertical tremor of battery case.
In the connection structure of above-mentioned Battery case and battery modules, the pressing plate includes being fixedly connected with the bottom plate
First mounting portion, the second mounting portion being fixedly connected with the mounting rack and connection first mounting portion and second installation
The middle part in portion, first mounting portion are connected with the bed bolt.It can ensure that the connection of pressing plate and Battery case bottom plate is steady
Solidity is conducive to buffer battery mould group in the intracorporal vertical tremor of battery case.
In the connection structure of above-mentioned Battery case and battery modules, the middle part includes from its top downwardly toward institute
The upper junction plate and the lower connecting plate being obliquely installed from its bottom end up towards the battery modules that battery modules are obliquely installed are stated,
The bottom end of the upper junction plate is connected with the top of the lower connecting plate and forms an obtuse angle.The upper and lower connecting plate of middle part is connected
And obtuse angle is formed, be conducive to the length for increasing middle part, the support force of middle part improved, to ensure that one-way wheel is securely pressed against
In on side wall, ensure one-way wheel to the buffer function of battery modules vertical tremor.
In the connection structure of above-mentioned Battery case and battery modules, second mounting portion is in straight panel shape.Structure letter
It is single, preparation easy to process.
In the connection structure of above-mentioned Battery case and battery modules, the upper end of second mounting portion is the same as the upper company
The upper end of fishplate bar is connected, and the lower end of second mounting portion is fixedly connected with the installation baffle of mounting rack.In this way by the second mounting portion
It is obliquely installed, is conducive to ensure that one-way wheel is securely pressed against on side wall.
Compared with prior art, the utility model has the advantage that the pressing plate by being installed on Battery case bottom plate,
And pressing plate upper end has the trend of the sidewall elastomer deformation to battery modules, the one-way wheel of pressing plate upper end can will be arranged in securely
It is pressed against on the side wall of battery modules.One-way wheel is only capable of opposing sidewalls and scrolls up, and offsets up when vibration occurs for battery modules
When, one-way wheel is in self-locking state, offsets up to form larger resistance to side wall, certainly after battery modules are upwardly deviated from
When the lower reset of recast, one-way wheel opposing sidewalls scroll up, and side wall is needing to overcome between one-way wheel and side wall in reseting procedure
Frictional force, battery modules can be improved in the intracorporal shock resistance of battery case.
