Abstract
The invention relates to a rechargeable lithium battery electric tool, comprising a clamping head part, a gearbox, a motor, a handle and a battery pack, wherein the battery pack is arranged inside the handle and comprises 4 lithium batteries, a battery shell and a battery base, the four lithium batteries are installed inside the battery shell the bottom of which is provided with the battery base, and the battery base is in inserted connection with the handle; the rechargeable lithium battery electric tool has the advantages that: the structure is simple and novel, the use is convenient; based on the basic design concept that the advantages of compact rechargeable lithium battery electric tools and large-power output rechargeable lithium battery electric tools are combined, the rechargeable lithium battery electric tool of the invention, on one hand, meets the power demand of large power output by adopting a 14.4V(14.4V to 16V) lithium battery system as power base and platform, and on the other hand, shortens own overall volume because the battery pack including the 4 lithium batteries is designed inside the handle. At the same time, the power of the tool is improved while the overall volume is reduced owing to the use of short rare earth motor.
Description
[technical field]
The present invention relates to the electric tool technical field, specifically a kind of employing 14.4V (14.4-16V) lithium electric system is the rechargeable lithium electricity electric tool of dynamic foundation, as electric drill, electric wrench, angle mill, sweep-saw etc.
[background technology]
At present, existing rechargeable lithium electricity electric tool mainly contains two types: a kind of is small and exquisite class, and another is high-power output class.Voltage with 3.6V, 7.2V and 10.8V is output as small and exquisite class on the market, is output as high-power output class (referring to Fig. 1) with the voltage of 14.4V (14.4-16V), 18V, 21.6V and 36V.
Small and exquisite class advantage is lightly, is easy to carry, and its shortcoming is that power is little, can not be used for high-power output products (all can not be applied in the platform of 3.6V, 7.2V and 10.8V as percussion drill, angle mill, sweep-saw etc.).Therefore, in small and exquisite lithium electricity electric tool product, have only products such as little electric drill, small flashlight, little wrench, pony knife saw and small-sized measuring instrument.
High-power output class advantage is that power output is big, and its shortcoming is that its small product size is big and heavy.Therefore, in high-power output lithium electricity electric tool product owing to reasons such as power brick can't be made the little electric tool of volume.
Above-mentioned existing rechargeable lithium electricity electric tool respectively has pluses and minuses, exists shortcoming separately simultaneously again.So the user needs the electric tool of 2-3 different stage could be suitable for different environments for use at least, thereby need the different voltage charging equipment of management, and the battery of many versions has also brought burden to environmental protection.
[summary of the invention]
Purpose of the present invention is exactly will solve above-mentioned deficiency and provide a kind of little fuselage and the rechargeable lithium of high-power output electricity electric tool, and is not only easy to use, and saves cost, and reduced the infringement that environmental protection is brought.
Design a kind of rechargeable lithium electricity electric tool for achieving the above object, comprise collet segment 1, gear-box 2, motor 3, handle 9 and power brick 6, described collet segment 1 connects upper gear box 2 by output shaft, described gear-box links to each other with motor 3 by motor gear, described motor connects gauge tap 5 by positive and negative polar curve, described gauge tap connects power brick 6 by terminal, it is characterized in that: described power brick is arranged in the handle 9, described power brick comprises 4 lithium batteries, battery case and battery base 8, described 4 lithium batteries are installed in the battery case, described battery case bottom is provided with battery base 8, described battery base socket connection handle 9.
The lower end part of described handle 9 is provided with cannelure 7, and described battery base is provided with the annular protrusion that matches with cannelure, and described annular protrusion is entrapped in the described cannelure 7.
Described power brick 6 output voltages are 14.4-16V.
Described motor 3 adopts rare earth 2 utmost points or 4 utmost point motors.
Described gear-box 2 adopts the metal-toothed roller box.
Beneficial effect of the present invention: novel structure, simply, easy to use, because the advantage in conjunction with small and exquisite class and high-power output class rechargeable lithium electricity electric tool is basic design concept, adopting 14.4V (14.4-16V) lithium electric system on the one hand is dynamic foundation and platform, satisfied the power demand of high-power output, the power brick design that will contain 4 lithium batteries on the other hand is in handle inside (existing with its design below handle), thereby dwindled the volume of electric tool integral body greatly, thereby realized that little fuselage is high-power, broken through the high-power output problem of small and exquisite type electric tool, and the volume of high-power output class electric tool is big and heavy problem.Simultaneously, owing to use the short motor of 14.4V (14.4-16V) rare earth, i.e. rare earth 2 utmost points or 4 utmost point motors, thus when dwindling the integral body volume, promoted the power of instrument again greatly, make its performance reach the 18V rechargeable power tool.In addition, adopt the all-metal gear-box among the present invention, promoted the life-span of pinion stand greatly; And the tapered end of cooperation 13mm then makes the entire product size reach the product size near 10.8V, can reach the performance of 18V product again.In sum; the present invention has not only promoted the power demand of the little and high-power output of electric tool integral body; the user only need manage different charging equipment problems with solving once cover battery scheme in the past simultaneously; promptly can ratio of elongation 10.8V on same design platform and the more kind of 18V product; significantly reduced the infringement that environmental protection is brought because of different battery strings, also reduced the cost of user management battery and charger.
