How note, improve course continuation mileage at present, improve the energy density of battery, and the safety for improving power battery becomes electronic vapour from now on
The key of vehicle development.
Core of the power battery module as electric automobile energy system, power battery module need energy with higher
Density enables electric car effectively to travel longer distance, it is necessary to stablize effective offer power, single battery is avoided to fail
The problem of causing, to guarantee that electric car is safe and reliable.
The design method of currently used power battery module encapsulating structure, usually not individually designed encapsulating structure,
Glue is directly injected into after mould group cavity and again sinks to battery core component in glue, the glue amount that this encapsulating mode uses is bigger, entirely
Mould group heavier-weight, glue can only play encapsulating, fixed function in mould group bottom.
Summary of the invention
The purpose of the utility model is to provide a kind of power battery module conductive structure glue encapsulating structures, it is intended to solve existing
Without individual encapsulating structure in the encapsulating structure of dynamic battery modules, and, entire mould larger using conventional method glue consumption
The technical issues of group heavier-weight.
To solve the above problems, one aspect according to the present utility model, provides a kind of thermally conductive knot of power battery module
Structure glue encapsulating structure, including copper bar bracket are provided at least one in copper bar stent cavity body for encapsulating stream of heat-conducting glue to be perfused
Road, encapsulating flow channel entry point are set to copper bar cradle top, and confluence copper bar installation cavity, encapsulating is arranged in the one or both sides of encapsulating runner
Runner bottom is communicated with confluence copper bar installation cavity bottom.
Further, confluence copper bar, sampling terminal, sampling harness are pre- solid by bayonet arrangement with copper bar bracket respectively
Fixed, sampling terminal is connected respectively at confluence copper bar with sampling harness.
Further, encapsulating runner bottom is provided with the first card slot, and the sampling harness connecting with sampling terminal passes through the
It is met at after one card slot in encapsulating runner.
Further, encapsulating runner top side is provided with the second card slot for being pierced by and fixing the harness of the sampling after converging,
On the outside of second card slot on copper bar bracket fixed sample harness output terminal.
Another aspect according to the present utility model provides a kind of power battery, including above-described power battery module
Conductive structure glue encapsulating structure.
In power battery module conductive structure glue encapsulating structure provided by the utility model, integrates and set on copper bar bracket
Counted encapsulating runner, water conservancy diversion carried out to heat-conducting glue by encapsulating runner, realized to the confluence copper bar of mould group bottom, sampling terminal and
Sample the fixation of harness.To reduce the weight of glue in adhesive filling mould group, it is close to promote product energy for Lifting Modules group group efficiency
Degree.Remaining glue is pasted on harness is sampled on copper bar bracket in encapsulating runner, and heat-conducting glue is efficiently used in having in mould group
Imitate space.
