Description

A kind of power brick

Technical field

The present invention relates to field of batteries, more particularly, it relates to a kind of power brick.

Background technology

Existing power brick, forms module by multiple cell or capacitor parallel connection, then forms the battery pack of certain voltage and capacity by multiple module connection in series-parallel, be placed in a casing sealed and make.

The voltage specification of power brick of the prior art is substantially all at below 60V, be difficult to accomplish the specification higher than 60V, trace it to its cause is because power brick can produce a large amount of heats in charge and discharge process, if these heats can not distribute in time, then can affect the useful life of battery pack, even there is security incident, and the voltage specification of power brick is higher, the heat produced in charge and discharge process is higher, so due to the heat dissipation problem of power brick well cannot be overcome in prior art, so be difficult to make the power brick higher than 60V.

Be called in the Chinese patent of " power brick " be also referred to this problem as application number is 201410534172.7, but the volume solving this technical problem the battery pack case of employing is comparatively large, practicality can be poor.

Summary of the invention

For the deficiency that prior art exists, the object of the present invention is to provide a kind of compact conformation and the strong power brick of heat dispersion.

For achieving the above object, the invention provides following technical scheme: a kind of power brick, comprise at least one pcb board and be located at least two battery units of connecting mutually on pcb board, described battery unit comprises the battery of multiple arrangement in quadrangle permutation, often the placement direction of adjacent two batteries is contrary, the conducting strip that the serial battery in each battery unit is got up is provided with in the two ends of described battery, the rear and front end of described battery is fixed with skeleton, described skeleton is provided with the hole clipping for self-contained battery end, is provided with louvre in skeleton.

By adopting technique scheme, the battery in tight rectangular arranged makes the smaller volume of whole battery unit, compact, and reduce the volume of power brick on the whole, volume one is little, and it is more convenient to use, the skeleton of self-contained battery is provided with louvre, battery unit heat dispersion can be increased again, by being arranged on the louvre on the skeleton at battery two ends, when at the two ends of power brick, radiator fan is set, the heat produced by power brick can distribute fast, and then play the effect of the strong thermal diffusivity of small size on the whole, when power brick adopts the specification of 120V voltage, the voltage specification of each battery unit can be made to reach 60V, two series connection reach 120V, realize the power brick of high voltage when normally working, the requirement of this excellent heat dispersion performance can also be had, avoid the low and problem that causes of heat dispersion that power brick of the prior art exists.

Be optimized for further: described conducting strip comprises conducting strip and lower conducting strip, described upper conducting strip comprises the conducting ring of vertical setting and upper haptic element, and described lower conducting strip comprises the conducting ring of horizontally set and lower haptic element, and described upper haptic element and lower haptic element are oppositely arranged.

By adopting technique scheme, because the placement direction of every adjacent two batteries is contrary, by conducting strip being arranged to this set of upper conducting strip and lower conducting strip, each battery unit is made to realize the effect of series connection.

Be optimized for further: described louvre is located at the center of the quadrangle of four hole clippings often adjacent on skeleton.

By adopting technique scheme, louvre is the center of the quadrangle being arranged on four often adjacent hole clippings, namely the intensity of skeleton is not affected, battery unit heat dispersion can be increased again, by being arranged on the louvre on the skeleton at battery two ends, and a passage will be formed between columniform battery every 4 batteries that are quadrangular array itself, so by the passage between the louvre on skeleton and battery, a complete heat dissipation channel can be formed, and organize louvre more and add that many group passages just can be formed and organize heat dissipation channel more, so each battery unit is provided with organize heat dissipation channel more, when at the two ends of power brick, radiator fan is set, the heat produced by power brick can be distributed fast by heat dissipation channel.

Be optimized for further: be equipped with insulation in the both sides of each battery unit every paper, be provided with the through hole corresponding with the louvre position on skeleton in insulation every paper.

By adopting technique scheme, in the volume both sides of battery unit, all insulating barrier is set, the power loss problem that the electricity of cell panel is occurred by fortuitous event and extraneous conductor conducting can be prevented, can ensure again that people to avoid when fetching battery plate by battery unit to hurting (safe voltage due to human body is 36V, and the voltage specification of power brick here is generally greater than 60V).

Be optimized for further: described louvre is rectangular, the diagonal of the louvre of described rectangle is arranged along the length and width direction of skeleton.

By adopting technique scheme, because louvre is the hole clipping center being arranged on 4 often adjacent rectangular permutations, when skeleton at retain batteries two ends time, hole clipping will by pressure is large slightly, namely there is certain deflection, and these deflections occurred can toward the extruding of louvre place, louvre is arranged to rectangular-shaped, and the diagonal of louvre is along the length of skeleton, cross direction is arranged, the extrusion deformation degree occurred will extrude toward the length and width perpendicular to louvre, the mode extruded to center compared to four summits along rectangle is out of shape and is more prone to, convenient when making retain batteries.

Be optimized for further: the wall surface of the hole of described louvre extends to battery direction, and is provided with the corresponding lateral wall of each hole wall the arcwall face mated with battery.

By adopting technique scheme, on skeleton when placing battery, battery separates one by one by by the hole wall of louvre, make place time convenient and fixing time stability greatly strengthen, and be provided with at the corresponding lateral wall of each hole wall the arcwall face mated with battery, while convenience is placed in increase, further turn increase the stationkeeping ability of battery on skeleton, make battery be not easy to occur rocking.

Be optimized for further: described lower PCB fixed head is provided with binding post.

The present invention's advantage is compared with prior art:

1, being fixed on skeleton by battery being arranged to compact rectangle permutation mode, reducing the volume of power brick on the whole;

2, be provided with on skeleton louvre do not have 4 adjacent rectangle permutations on the battery of rectangle permutation under battery between form heat dissipation channel together with the passage that formed, the heat dispersion of power brick is sharply increased, provides the prerequisite that large gauge power brick can work;

3, louvre is set as rectangle and its diagonal is arranged along the diagonal of louvre along the length and width direction of skeleton, when making to install battery in convenient embedding hole clipping;

4, by louvre towards the extended hole wall in battery direction, convenient when making placing battery, and add the stationkeeping ability of battery.

5, by arranging insulation every paper, reducing the electric leakage probability of power brick, and protecting the safety in utilization of people.
