Abstract
The aluminium sheet that the utility model discloses a kind of explosion-proof cover plate of lithium ion, comprises plate body, and plate body is rectangle, a circular port is offered at plate body middle part, plate body two ends all offer shape hole, a positive n limit, n >=4, and shape hole, two positive n limits is parallel with the line of circular port and the long limit of plate body.The beneficial effects of the utility model are: the circular port contacting with pole on the aluminium sheet of traditional explosion-proof cover plate of lithium ion is changed and is made as shape hole, positive n limit, n >=4, greatly improve the fixing fastness of aluminium sheet and pole, effectively prevented battery in the process using because the bolt turning on pole drives polar-column rotation, cause becoming flexible of pole and aluminium sheet and cause battery to be scrapped.
Description
Technical field
The utility model relates to technical field of lithium ion, is specifically related to a kind of aluminium sheet of explosion-proof cover plate of lithium ion.
Background technology
Electric automobile has the remarkable advantages such as energy-saving and environmental protection, light, safe, quick, usage charges are low, electric automobile is one of trip mode of people's routine work, life thus, be the industry direction that country encourages, apply with technological development and day by day come into one's own.Obvious, the research and development of lithium ion battery are important topics that promotes electric automobile extensive use.
As shown in Figure 1, because pole and the aluminium sheet contact site of lithium ion battery are in the market circular ports, cause being very easy to rotate twist bolt on pole time, cause pole and aluminium sheet loosening, can make battery scrap.
Therefore, how to improve the stability of the aluminium sheet of anti-explosion cover plate of power lithium ion, make fixing more firm of aluminium sheet and pole, become the current problem solving of needing.
Utility model content
Be circular port for solving the position that the aluminium sheet of explosion-proof cover plate of lithium ion of the prior art contacts with pole, while causing twisting bolt on pole, easily rotate the technological deficiency that battery is scrapped, the utility model is designed a kind of aluminium sheet of explosion-proof cover plate of lithium ion, realize the object that improves the aluminium sheet stability of explosion-proof cover plate of lithium ion, what also make that aluminium sheet and pole fix is more firm simultaneously, has avoided battery to scrap.
For achieving the above object, the technical solution adopted in the utility model is:
An aluminium sheet for explosion-proof cover plate of lithium ion, comprises plate body, and plate body is rectangle, and a circular port is offered at plate body middle part, and plate body two ends all offer shape hole, a positive n limit, n >=4, and shape hole, two positive n limits is parallel with the line of circular port and the long limit of plate body.The circular port contacting with pole on the aluminium sheet of traditional explosion-proof cover plate of lithium ion is changed and is made as shape hole, positive n limit, n >=4, greatly improved the fixing fastness of aluminium sheet and pole, effectively prevented battery in the process using because becoming flexible of pole and aluminium sheet causes battery to be scrapped.
Further, n=4, shape hole, positive n limit is square opening, and four angles of square opening are fillet.For attractive in appearance, the steel pad of riveting on pole covers square opening, designs four fillets and can dwindle the occupied area of square opening, thereby dwindle steel pad diameter.
Preferably, the peripheral portion of plate body bottom surface offers circumferential slot.The welding of convenience and battery case.
Preferably, the equal founding of inner edge portion in the circular port of plate body and shape hole, positive n limit has rubber cushion.Founding rubber cushion, has the following advantages: 1, make pole and aluminium sheet insulation, if there is no rubber cushion, positive and negative pole has just been connected by aluminium sheet.2, prevent gas leakage.3, rubber cushion adopts soluble poly tetrafluoroethene (pfa) to be made, high temperature resistant.
Preferably, the bottom at four of plate body angles is all connected with circular gasket.Can facilitate individual's dismounting.
The beneficial effects of the utility model are: the circular port contacting with pole on the aluminium sheet of traditional explosion-proof cover plate of lithium ion is changed and is made as shape hole, positive n limit, n >=4, greatly improve the fixing fastness of aluminium sheet and pole, effectively prevented battery in the process using because the bolt turning on pole drives polar-column rotation, cause becoming flexible of pole and aluminium sheet and cause battery to be scrapped.
