Description
Technical field
The utility model is related to battery pack technical fields, and in particular to a kind of novel battery packet liquid-leakage preventing backplate.
Background technology
Electric vehicle has become the trend of current development of automobile industry because of the advantages of its energy conservation and environmental protection.But electric vehicle
Battery pack fever phenomenon in use be worth noting and study the problem of.The presence of its heat not only influences
The performance of battery, and there is safety problems.Therefore the heat management system of battery pack is electric vehicle and hybrid power in institute
Essential auxiliary system in safe and effective driving process under some operating modes and environment.
It is mainly directly radiated to battery system using liquid cooling mode both at home and abroad at present, passes through condenser and its attachment tube
Road carries out forced heat radiation or heating to battery pack, preferably resolves battery pack heat management problems, but liquid cooling system there is also
It is easy the risk of leakage, main cause is that battery pack internal interface is numerous, and automotive service environment is more severe, at battery pack
It is given a shock in long-term or the problems such as when external strong impaction extremely be easy to cause the fracture of coolant liquid pipeline, and interface loosens, makes
Cold or refrigerant is cooled down at battery pack to be directly discharged into inside battery pack, causes the things such as battery core insulation short circuit or even explosion on fire
Therefore serious security risk is caused to passenger.
Utility model content
To achieve the above object, the utility model uses following technical scheme：
A kind of novel battery packet liquid-leakage preventing backplate, including panel reality are provided with mounting hole, water conservancy diversion on the panel reality
Slot, valve unload liquid valve；It is provided with radiating fin on the bottom surface of the panel reality.
Further, the valve is one-way cock.
Further, the radiating fin is vertical with panel reality.
Further, the diversion trench is at least two row, and each row diversion trench is evenly distributed on panel reality 7, described
Valve unloads liquid valve and is arranged in the centre position of adjacent two row diversion trench.
Further, a circle seal washer is provided on the panel reality.
Further, the material of the diversion trench and panel reality is aluminium alloy.
Further, the diversion trench is rectangle.
In the present invention, the effect of diversion trench is to form a water storage structure in structure upper surface, and coolant liquid passes through
Diversion trench flows near drainage valve, while diversion trench can further enhance the heat-sinking capability of battery pack；Unload the main function of liquid valve
It is after leakage occurs for battery pack, liquid unloads liquid valve by the guiding device below flow direction valve battery pack eventually by opening will
Liquid is discharged outside battery pack, ensures the electrical shock safety that battery pack causes by leakage；In the radiating fin of panel reality bottom setting
It is main to act the battery that radiates and protect.The utility model is simple in structure, is leaked by installing backplate in battery pack bottom
Liquid collect, unload liquid valve can timely by the leakage in battery pack carry out isolation be discharged into the external world, improve the peace of battery system
Full performance.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of another angles of Fig. 1；
Fig. 3 is the use state reference chart of the utility model；
In figure, 1, diversion trench, 2, seal washer, 3, radiating fin, 4, one-way cock, 5, unload liquid valve, 6, panel reality, 7,
Mounting hole.
Specific implementation mode
As shown in Figure 1-Figure 3, a kind of novel battery packet liquid-leakage preventing backplate, includes the panel reality 6 of aluminium alloy, entire backplate
Ontology 6 is mainly made by aluminium alloy, and the bottom surface of battery pack is fixed on by mounting hole 7, and aluminium alloy improves entire battery pack
Rigidity, while effectively reducing ground stone and the injury caused by battery pack such as hitting；A circle gasket is provided on the panel reality 6
Circle 2,2 main function of seal washer is to seal, and ensures the IP grades of battery pack.Peace is provided on the panel reality 6
Liquid valve 5, one-way cock 4, is unloaded at the rectangular guiding slot 1 of aluminium alloy in dress hole 7, and the main function of 1 part of diversion trench is by one-way cock
4 coolant liquids flowed out, which are directed to, unloads near 5, liquid valve, can preferably be arrived coolant drain when unloading 5, liquid valve and opening
Outside battery pack, while diversion trench 1 can also play reinforcement battery pack intensity and against shock, can be preferably in battery pack and road
One layer of protection is formed between face；Issuable coolant liquid inside battery pack is imported on panel reality 6 by one-way cock 4,
And timely discharged coolant liquid by unloading liquid valve 5, ensure the safety of battery pack；It is set on the bottom surface of the panel reality 6
It is equipped with the radiating fin 3 vertical with panel reality, this direction advantageously reduces air resistance coefficient and energy in vehicle traveling process
Ensure that each fin wind speed is uniform, heat dissipation is good, and radiating fin 3 improves the work of the heat-sinking capability and protection battery of battery system
With.The diversion trench 1 is two row, and each row diversion trench 1 is evenly distributed on panel reality 6, and the one-way cock 4 unloads liquid valve 5
It is arranged in the centre position of adjacent two row diversion trench 1.
In use, the problems such as coolant liquid or refrigerant are in case of pipe leakage or rupture, battery pack is leaked
After liquid, cause battery core that will be immersed directly in liquid, liquid flows to the liquid in battery pack by one-way cock 4 and is discharged into protection
In backplate, later period maintenance personnel can be unloaded liquid valve 5 by opening and liquid is discharged outside battery pack.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
