Abstract
The invention provides a novel design of a power storage device cover board. A through liquid filling hole is formed on the power storage device cover board, and flow guide grooves which are directly or indirectly communicated with the liquid filling hole are formed below the hole and on the bottom surface of the cover board. In the design, the height of the bottom of the hole is increased, whichcan greatly reduce the hidden danger of causing accidents by touching the inner part of a power storage device in the process of sealing the hole of the power storage device cover board, so that the hole can be sealed by riveting, steel ball hitting and the like. By adding a design structure of cover board flow guide grooves, electrolyte is more conveniently filled into the inner part of the power storage device, the speed of filling the electrolyte is increased, the problem of difficult liquid filling due to too closely combined internal parts and a shell of the power storage device can be solved, and as the internal parts and the shell of the power storage device are closely combined, not only the inner space of the power storage device is more effectively used, but also the internal parts of the power storage device are difficult to move, the hidden danger of moving the internal parts of the power storage device is eliminated, and the safety of the power storage device is increased.
Description
Technical field
The present invention relates to a kind of energy storage device cover plate and make the field, be specifically related to a kind of energy storage device structure of cover plate design with guiding gutter structure.
Background technology
Along with popularizing of energy storage device, people are more and more higher to the performance requirement of energy storage device, and then the energy storage device of various structure occurred, and wherein the design kind to the energy storage device cover plate is also a lot.
Energy storage device cover plate design is mainly at present: cover plate is designed to circular or square, on the cover board processes liquid injection hole and blast resistance construction is installed thereon.Application number is that 200720119909.4 patent on the cover board is provided with liquid injection hole, and combines closely with rivet and liquid injection hole, and this kind structure rivet is installed the improper energy storage device inside of easily touching and caused danger.Application number be 200610150321.5 patent because the restriction of its lug makes its inner space well do not utilized, have vacantly, make that the parts of energy storage device inside are easily movable, the potential safety hazard that causes internal part to damage the formation accident is arranged.Though other relevant cover plate patent can accomplish to make energy storage device internal part and energy storage device housing to combine closely, but do not consider to the inner difficulty or ease problem of annotating electrolyte of energy storage device, the present invention goes out guiding gutter in energy storage device cover plate bottom design, makes the easier energy storage device inside that is injected into of electrolyte.
Summary of the invention
The objective of the invention is: the some shortcomings at existing energy storage device cover plate exists provide a kind of new energy storage device covering plate structure.
Energy storage device covering plate structure proposed by the invention can overcome the defective of above product, design the hole that connects the energy storage device cover plate at the energy storage device cover plate, below described cover board hole, be processed with guiding gutter, this kind design has promoted the height of bottom, hole, increased the distance of hole and energy storage device internal part, so the sealing in hole can not be confined to rivet, pound modes such as steel ball.Guiding gutter is set up in the below of energy storage device cover board hole, more convenient to the inner electrolyte of annotating of energy storage device, increase the speed of annotating electrolyte, can solve energy storage device internal part and its housing too closely and the problem of fluid injection difficulty, and energy storage device internal part and its housing are combined closely, more efficient use energy storage device inner space.Project organization of the present invention is for achieving the above object:
A kind of energy storage device cover plate is provided with the liquid injection hole that runs through it at described cover plate, it is characterized in that: below liquid injection hole and the cover plate bottom surface be provided with the guiding gutter that is connected with this hole.
The layout of guiding gutter of the present invention on the cover plate bottom surface comprises any one rule or irregularly shaped in linear, radiation, the spirality, and each road guiding gutter all directly or indirectly is connected with described cover plate liquid injection hole.
Described guiding gutter structure comprises square groove, arc groove, v-depression any one rule or irregularly shaped in them.
Also be provided with reinforcement in described lid surface and with the guiding gutter corresponding position of bottom surface, the layout of reinforcement is consistent with guiding gutter.
The structure of liquid injection hole comprises circle, ellipse, square any one rule or irregularly shaped in them on the described cover plate, and liquid injection hole is located at any position above the cover plate and connects cover plate.
On described cover plate, also be provided with explosion-proof or pressure relief device.
The material of described cover plate is selected from one or more in copper or copper alloy, nickel-clad copper alloy, aluminum or aluminum alloy, nickel or the metal or metal alloy such as nickel alloy, stainless steel; The shape of cover plate is decided its requirement according to energy storage device.
Described cover plate with guiding gutter structure be fit to energy storage device in positive pole ear, negative lug with the syndeton of welding, riveted joint, crimping or alternate manner.
Described cover plate with guiding gutter structure is applied to comprise any one energy storage device in lithium ion battery, ultracapacitor, mixed capacitor, high power battery, electrochemical capacitor, double electric layer capacitor, the capacitor batteries.
Characteristics of the present invention are: described energy storage device cover plate shape requires according to the energy storage device housing and decides, and run through energy storage device cover plate liquid injection hole below increased the design of guiding gutter, promoted the height of energy storage device cover board hole bottom, make liquid injection hole and energy storage device inside have more remote, can not touch the energy storage device internal part even use the method for this kind rivet sealing yet, be difficult in the process of sealing liquid injection hole, touching the energy storage device internal part and causing the accident, so the sealing means in hole can be selected riveted joint, pound steel ball etc.; Guiding gutter is designed in the below of energy storage device cover board hole, more convenient to the inner electrolyte of annotating of energy storage device, increase the speed of annotating electrolyte, can solve energy storage device internal part and its housing too closely and the problem of fluid injection difficulty, and energy storage device internal part and its housing are combined closely, more efficient use energy storage device inner space, it is movable that the energy storage device internal part is difficult for, elimination increases the fail safe of energy storage device because of the movable hidden danger of bringing of energy storage device internal part.
