Abstract
The present invention provides a kind of tamper-proof lithium battery, and pond includes cylindrical battery main body, and the permanent magnetism column for extending to battery main body upper and lower side is arranged in the inside of a bus of the battery main body.The permanent magnetism column is made of kicker magnet, such as neodymium iron boron.The tamper-proof lithium battery has good preventing destructing performance, and structure is simple it is possible to prevente effectively from cone cell or knife-like ironware destroy it.
Description
Technical field
The present invention relates to field of batteries, particularly, are related to a kind of lithium battery.
Background technique
Lithium battery is all very universal in each field due to haveing excellent performance；However, since lithium ion chemical activity is stronger, lithium
The risk of ion is also higher, and physical damage can not be especially carried out to lithium battery, is such as broken lithium battery using cone or cutter
Bad when, is easy to the positive and negative anodes for keeping it internal short circuit, then lithium battery fast heating will be caused to burn, or even explosion.
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of tamper-proof lithium battery, which can be with
Effectively cone cell or knife-like ironware is avoided to destroy it, there is good preventing destructing performance, and structure is simple.
The technical solution adopted by the present invention to solve the technical problems is: the tamper-proof lithium battery includes cylindrical battery
The permanent magnetism column for extending to battery main body upper and lower side is arranged in main body, the inside of a bus of the battery main body.
Preferably, the permanent magnetism column is made of kicker magnet, such as neodymium iron boron.
Preferably, the permanent magnetism column includes the stem being made of kicker magnet, and be made of iron pipe, the package core
The outer wall of column；When so that even if battery main body being switched to by cutter, the permanent magnetism column with can by the outer wall that the iron pipe is constituted come
Bear cutting.
Preferably, the mid diameter of the battery main body is slightly larger than both ends diameter, make battery main body when horizontal positioned,
Both ends are hanging.
The beneficial effects of the present invention are: the tamper-proof lithium battery using cone cell or knife-like ironware when being destroyed, due to it
Internal bias has the permanent magnetism column of close battery main body side, will make utensil when close to battery main body, battery main body is in magnetic
The lower deflection of power effect, and be adsorbed on irony utensil upwards, cause in the case where not battery main body fixed by other toolings,
Irony utensil is difficult to destroy it.
Detailed description of the invention
Fig. 1 is the side schematic view of this tamper-proof lithium battery embodiment one.
Fig. 2 is the end of this tamper-proof lithium battery embodiment one to schematic diagram.
Fig. 3 is this movement schematic diagram of tamper-proof lithium battery embodiment one when cutter is close.
Fig. 4 is the side schematic view of this tamper-proof lithium battery embodiment two.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
In Fig. 1, embodiment shown in Fig. 2 one, which includes cylindrical battery main body 1, the electricity
The permanent magnetism column 2 for extending to battery main body upper and lower side is arranged in the inside of one bus of tank main body 1；The permanent magnetism column 2 is by strong
Magnet is constituted, such as neodymium iron boron.
Above-mentioned tamper-proof lithium battery using cone cell or knife-like ironware when being destroyed, since its internal bias has close battery master
The permanent magnetism column 2 of body side, will make utensil when close to battery main body, and battery main body 1 deflects under magneticaction, and upwards
It is adsorbed on irony utensil；Such as in cone cell ironware downwards close to battery main body 1 when, battery main body 1 closer from cone cell ironware one
End is upturned under magnetic attraction effect first, and is vertically adsorbed in cone cell ironware side, leads to not carry out battery main body 1
Hammering；And when the battery main body 1 that the downward cutting horizontal of cutter is placed, as shown in figure 3, since manual operations is difficult to make cutter 3
2 length of permanent magnetism column of two sides is essentially equal, the magnetic attraction between the permanent magnetism column 2 and cutter 3 of 3 side of cutter must be made to be greater than another
Side to make battery main body 1 roll and rotate to being parallel to cutter 3, and is adsorbed in cutter side upwards；It can be seen that the electricity
In the case where no tooling is fixed, irony utensil is difficult to destroy it tank main body 1.
In addition, for the permanent magnetism column 2, it may include the stem being made of kicker magnet, and be made of iron pipe, package institute
State the outer wall of stem；Even if when so that battery main body being switched to by cutter, the permanent magnetism column is outer with can pass through that the iron pipe constituted
Wall bears to cut.
For embodiment two shown in Fig. 4, what is different from the first embodiment is that the mid diameter of the battery main body 1 omits
Greater than both ends diameter, e.g., 1.05-1.10 times of the mid diameter both ends diameter of battery main body 1 can be made, battery main body 1 is made to exist
When horizontal positioned, both ends are hanging；In this way, battery main body 1 can be made while not substantially changing the shape of battery main body 1
Rotational resistance is greatly reduced.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, made any modification, equivalent replacement be should all be included in the protection scope of the present invention.
