Abstract

The invention provides a folded battery pack and an electric tool using it. The folded battery pack comprises a plurality of battery packs, and the battery packs are electrically connected in a rotary manner. Batteries are connected in a rotary manner, so the obtained folded battery pack has different shapes; and when the folded patter pack is installed on the electric tool, the folded battery pack can be folded or unfolded as needed in order to provide convenience for the fixation to the electric tool. The versatility of the folded battery pack is good.

Description

Folding power brick and electric tool

Technical field

The present invention relates to a kind of supply unit, particularly relate to a kind of folding power brick and use the electric tool of this folding power brick.

Background technology

In electric tool, electric tool usually can adopt battery as power supply.Be generally now that battery is first fixed in power brick, and then power brick is arranged on electric tool.Wherein, battery is that the position fixed and form are combined and become a power brick, and the profile of power brick cannot change.When such power brick is arranged on electric tool, while easily causing different electric tools to mate with power brick, there is the defects such as accessibility is bad, space waste, complete machine proportional imbalance.For example, for part electric tool, due to the shape and size of electric tool, when battery-arrangements is grown up to bar shaped, using can be convenient, and the ratio regular meeting of whole electric tool is more balanced, and space availability ratio is also high; And to other a part of electric tool, using battery-arrangements may be become approach foursquare shape time can be more convenient, the ratio regular meeting of whole electric tool is more balanced, and space availability ratio is higher.

Therefore, conventional power brick only has fixing shape, cannot meet the needs of different electric tools, easily causes the unbalanced etc. of the waste in inconvenience, space of use or ratio.Conventional power brick versatility is poor.

Summary of the invention

Based on this, the electric tool that is necessary to provide a kind of power brick and uses this power brick, this power brick has advantages of that versatility is good.

A kind of folding power brick, comprises multiple power brick, and described multiple power brick are rotatably connected, and described multiple power brick are electrically connected mutually.

In an embodiment, the edge of described multiple power brick is equipped with hinge therein, and described multiple power brick link together by hinge through.

In an embodiment, the edge at the relative two ends of described multiple power brick is equipped with hinge therein, and described multiple power brick join end to end by described hinge.

In an embodiment, in described multiple power brick, one end relative with described hinge is provided with the buckle that two power brick are fixed together therein.

In an embodiment, described multiple power brick are electrically connected mutually by described hinge therein.

In an embodiment, the quantity of described multiple power brick is two therein.

A kind of electric tool, comprises folding power brick, and described folding power brick comprises multiple power brick, and described multiple power brick are rotatably connected.

Above-mentioned folding power brick is rotatably connected multiple power brick, this folding power brick just can have different shapes like this, in the time that this folding power brick is arranged on electric tool, just can as required that this folding power brick is foldingly or not folding be beneficial to fix with electric tool.Therefore this folding power brick has advantages of that versatility is good.

Fig. 2 is folding power brick folded state schematic diagram shown in Fig. 1.

Embodiment

Please refer to Fig. 1 and 2, one embodiment a kind of folding power brick 100 is provided.This folding power brick 100 comprises multiple power brick, and these power brick are rotatably connected.And these power brick are electrically connected mutually.

In this embodiment, the quantity of power brick is two, is respectively the first power brick 110 and the second power brick 120.120 li of the first power brick 110 and the second power brick are all equipped with at least one battery.The edge of the first power brick 110 and the second power brick 120 is equipped with hinge 130.The first power brick 110 and the second power brick 120 are rotatably connected by hinge 130, and are electrically connected mutually by hinge 130.Circuit connecting relation between the first power brick 110 and the second power brick 120 can be that parallel connection can be also to connect herein.Like this, the first power brick 110 just can be rotated with respect to the second power brick 120, thereby changes the shape of this folding power brick 100.Between certain the first power brick 110 and the second power brick 120, also can adopt other suitable rotational coupling mechanism, for example rotating shaft.

As shown in Figure 1, now this folding power brick 100 folds, but all trail.Shape when Fig. 1 has shown this folding power brick 100 extended configuration.That is to say, this folding power brick 100 has longer length, shorter width.As shown in Figure 2, now this folding power brick 100 has been folded in together.That is to say, this folding power brick 100 has shorter length, longer width.Shape when Fig. 2 has shown this folding power brick 100 folded state.Like this, this folding power brick 100 just has two kinds of different shapes.When use, just can select according to shape and the size etc. of electric tool a certain shape of this folding power brick 100.Like this, in the time that the folding power brick 100 with suitable shape is arranged on electric tool, the space on electric tool is used will be more reasonable, and ratio is just more balanced, is also just difficult for making troubles to use.Therefore, this folding power brick 100 just has advantages of that versatility is good.

Further, the first power brick 110 is with in the second power brick 120, relative one end is provided with the buckle that the first power brick 110 and the second power brick 120 are fixed together with hinge 130.Mutually folding when the first power brick 110 and the second power brick 120 is that buckle can be fixed up the first power brick 110 and the second power brick 120, to prevent that the first power brick 110 and the second power brick 120 are separated from each other.

In other embodiments, the quantity of power brick can be two incessantly, for example, can be three, four etc.When the quantity of power brick is during more than two, when these power brick are mutually folding, can fold out more shape, thereby meet different needs.Now, the edge at the relative two ends of power brick can all be provided with hinge, between multiple power brick, can join end to end by hinge.

Another embodiment provides a kind of electric tool, and this electric tool comprises a folding power brick being installed on electric tool.These power brick are rotatably connected, and these power brick are electrically connected mutually.Folding power brick herein adopts the folding power brick 100 in an embodiment.

The edge of each power brick of the folding power brick of this electric tool is equipped with hinge, and these power brick link together by hinge through.Meanwhile, hinge also has the effect of electric connection, and these power brick are electrically connected mutually by hinge.One end relative with hinge in power brick is also provided with the buckle that two power brick are fixed together.In the time that folding, two batteries can interfix by buckle like this.

Cannot not live foldingly because the folding power brick of this electric tool can fold, therefore the folding power brick of this electric tool can have different shapes.This folding power brick just can be fixed on electric tool with suitable shape like this, thereby makes the space layout of electric tool more reasonable.

The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
