The present invention also provides a kind of battery compartment, is arranged with one and makes it axial shrinkage and make the electrode that is wrapped by expose the pressurizing unit that contacts with the contact by pushing described elastic insulated sleeve after described lithium battery is positioned over this battery compartment outside the battery compartment contact of the described electrode of lithium cell of correspondence.
The present invention also provides a kind of supply unit, comprises lithium battery and battery compartment, is coated with an axial length greater than the elastic insulated sleeve of described electrode length at electrode surface of lithium battery; Being arranged with one outside the battery compartment contact makes it axial shrinkage and makes the electrode that is wrapped by expose the pressurizing unit that contacts with the contact by pushing described elastic insulated sleeve after lithium battery is positioned over this battery compartment.
The present invention realizes self-short-circuit protection in the time of can making lithium battery at idle state by the elastic insulated sleeve that coats a band gap, top at electrode surface of lithium battery; Be arranged with the pressurizing unit for this elastic insulated sleeve of extruding outside the battery compartment contact that is used in conjunction with, thereby after this lithium battery is packed this battery compartment into, by being located at this elastic insulated sleeve of pressurizing unit extruding of periphery, battery compartment contact, make elastic insulated sleeve deformation axial shrinkage, electrode of lithium cell contacts with the battery compartment contact like this, and lithium battery can work.
Description of drawings
The structural representation of the lithium battery that Fig. 1 embodiment of the present invention provides and the battery compartment that is used in conjunction with;
The lithium battery that Fig. 2 embodiment of the present invention provides is placed on the schematic diagram after the battery compartment that is used in conjunction with.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
The present invention is coated with the elastic insulated sleeve in a band gap, top by electrode surface of lithium battery, and being arranged with a pair of pushing of answering outside the battery compartment contact that is used in conjunction with, pressurizing unit that this elastic insulated sleeve makes it axial shrinkage realizes.
Referring to Fig. 1-2, a kind of lithium battery is coated with an axial length greater than the elastic insulated sleeve 4 of described electrode 5 length at electrode 5 outer surfaces of lithium battery 6, has the gap on the top of described elastic insulated sleeve 4.
Described gap can be that the cross gap of establishing formation is stretched out in the top end face center of own elasticity insulating sleeve 4 to the outer, can be also the in-line gap, or the gap of other shape, and concrete shape is not limit.
Described elastic insulated sleeve 4 bottoms and lithium battery 6 case surface link together.More excellent, connect as one by bonding way.
The cross section of described elastic insulated sleeve 4 can be circular, also can square other shape such as grade, and concrete shape is not limit.
Described elastic insulated sleeve 4 can be made by rubber, also can be made by other elastic insulated material, and more excellent is made by elastic caoutchouc.
Referring to Fig. 1-2, of the present inventionly also provide a kind of battery compartment, be used for coordinating aforesaid lithium battery to use, be arranged with one and play insulating properties sleeve 4 by extruding make it axial shrinkage and make the electrode 5 that is wrapped by expose the pressurizing unit 2 that contacts with contact 3 after lithium battery 6 is positioned over this battery compartment 1 outside the contact 3 of the battery compartment 1 of the described electrode of lithium cell of correspondence.
The direction of extrusion of pressurizing unit 2 is as shown in the direction of arrow in Fig. 1.
The axial length of described pressurizing unit 2 is greater than described contact 3 height, what it can be provided in a side of periphery, described contact forms the rigid sleeve of full enclosed structure to the contact, can be also a side band opening, the sleeve that the contact is formed the semi-surrounding structure, can be also two, three or several stripper plates that evenly are located at the outside, described contact, described contact be need not to form full enclosed structure.
More excellent, described pressurizing unit 2 adopts the full telescoping structure that surrounds.
The bottom of described pressurizing unit 2 and battery compartment 1 surface link together.
More excellent, connect by bonding way; Pressurizing unit should adopt dielectric rigid material to make, can rigid plastics, glass or other dielectric hard material make.
Due to the axial length of described elastic insulated sleeve 4 axial length greater than parcel electrode 5, so just can form effective parcel to electrode, thereby realize the effective protection to electrode of lithium cell 5.
The object of the invention also is to provide a kind of supply unit, comprises lithium battery and battery compartment, shown in Fig. 1-2, is coated with an axial length greater than the elastic insulated sleeve 4 of described electrode 5 length on lithium battery 6 electrode 5 surfaces; Being arranged with one outside battery compartment contact 3 makes it axial shrinkage and makes the electrode 5 that is wrapped by expose the pressurizing unit 2 that contacts with contact 3 by pushing described elastic insulated sleeve 4 after lithium battery 6 is positioned over this battery compartment 1.
Further, described pressurizing unit is the rigid sleeve that is located at periphery, described contact, and its axial length is greater than described contact height.
Due to the axial length of described elastic insulated sleeve 4 axial length greater than parcel electrode 5, so just can form effective parcel to electrode, thereby realize the effective protection to electrode of lithium cell 5.
Still referring to Fig. 1-2, when being a plurality of in the contact of electrode of lithium cell and battery compartment, make the elastic insulated sleeve 4 on a plurality of electrodes 5 that wrap in side by side and be located at and keep certain spacing distance between the pressurizing unit 2 in 3 outsides, contact, so that when the deformation axial shrinkage occurs in elastic insulated sleeve 4 at the same time, can not interfere each other, can not affect the normal use of lithium battery.
When lithium battery was in idle state, elastic insulated sleeve did not stress, and kept original profile that electrode is wrapped in inside.Due to the resilient force of elastic insulated sleeve, metal object, water etc. easily causes the conductive body of inter-electrode short-circuit to be opened by isolated; When battery is placed into when in running order in corresponding battery compartment, the inner pressurizing unit of battery compartment can be exerted pressure to elastic insulated sleeve, makes elastic insulated sleeve deformation and axial shrinkage is exposed parcel electrode wherein, and then contact with contact in battery compartment, realize normal operation; After taking out battery, the pressure that comes from pressurizing unit disappears, and elastic insulated sleeve recovers original form, and electrode is wrapped up, and plays the effect of protection battery electrode.
The present invention is based on the elastic deformation characteristics of elastic insulating material with what realize, and it both can protect battery electrode to avoid the short circuit of the conductive bodies such as extraneous water, metal, can guarantee again the normal realization of battery electrical property.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
