Abstract
The utility model discloses a structure convenient to welding gap detects, including busbar and electric core, be equipped with the electrode on the electric core, electrode and busbar welded connection, the busbar is equipped with the clearance inspection hole with the electrode contact position, the utility model discloses set up clearance inspection hole structure in busbar and electrode connection part position, can accurately reach the clearance between busbar and the electrode through the busbar thickness convenience that highly subtracts that detects busbar upper surface and electrode surface to judge the tight quality of subsides of busbar and electrode, ensure busbar and electrode welded's technology reliability.
Description
Technical field
This utility model is related to electric vehicle battery system welding field, particularly relate to a kind of be easy to welded gaps detection
Structure.
Background technology
With the fast development of new-energy automobile, the integrity problem of new energy car battery system has also obtained increasingly
Many attention.
Connected together by laser welding between current electric vehicle battery system bus-bar and electrode, bus-bar with electricity
The welding quality of pole directly influences the reliability of battery system, and welding quality is adjacent to gap very to bus-bar and electrode
Sensitivity, gap is crossed conference and the quality problems such as is caused weld strength to decline, bores a hole.
Therefore, how to provide a kind of be easy to welded gaps detection device, can rapidly and accurately detect bus-bar with
Interelectrode weld gap, becomes a difficult problem in face of those skilled in the art for the pendulum.
Content of the invention
The purpose of this utility model is to provide a kind of structure being easy to welded gaps detection, using weld seam detection hole knot
Structure, can rapidly and accurately detect the gap between bus-bar and electrode, efficiently solve foregoing problems.
This utility model is achieved through the following technical solutions：
A kind of structure being easy to welded gaps detection, includes bus-bar and battery core, battery core is provided with electrode, electrode and remittance
Stream row be welded to connect, and bus-bar and electrode contact position are provided with gap detection hole.
Preferably, described gap detection hole is one or more.
Preferably, described gap detection hole is on weld seam.
Preferably, described gap detection hole is located at weld seam periphery.
It should be appreciated that aforementioned description substantially and subsequently detailed description are exemplary illustration and explanation, should not
As the restriction to the claimed content of this utility model.
The beneficial effects of the utility model are：
1st, this utility model arranges gap detection pore structure in bus-bar and electrode connecting portion position, can be confluxed by detection
The height of row's upper surface and electrode surface deducts the gap that bus-bar thickness easily and accurately draws between bus-bar and electrode, from
And judge the welding quality of bus-bar and electrode it is ensured that the reliability of bus-bar and electrode welding.
2nd, this utility model structure is simple, and detection quick and precisely, is easy to be extended and applied.
Brief description
With reference to the accompanying drawing enclosed, the more purpose of this utility model, function and advantage will be by this utility model embodiment party
