These features of the present utility model and advantage will be detailed in following detailed description of the invention, accompanying drawing exposure.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further:
Fig. 1 is the integrally-built exploded perspective view of brushless electric machine Gao Zhiju in this utility model preferred embodiment.
Detailed description of the invention
The technical scheme of this utility model embodiment is explained and illustrated by the accompanying drawing below in conjunction with this utility model embodiment, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, those skilled in the art are obtained other embodiments on the premise of not making creative work, broadly fall into protection domain of the present utility model.
As shown in Figure 1, brushless electric machine Gao Zhiju in this utility model preferred embodiment includes body, connecting tube 7 and Handleset, body includes brushless electric machine 1, electric machine controller 2 and casing 3, compared with brush motor, it is high that brushless electric machine 1 has work efficiency, slow-speed of revolution moment of torsion is big, the feature that high-precision rotating speed controls, owing to the winding of brushless electric machine 1 is three-phase, therefore brushless electric machine 1 and electric machine controller 2 are connected by three core connecting lines 21, brushless electric machine 1 and electric machine controller 2 are fixedly mounted in casing 3, casing 3 is fixedly mounted on the front end of connecting tube 7 by screw 10, casing 3 can prevent brushless electric machine 1 and electric machine controller 2 from extraneous injury.
Brushless electric machine 1 in this utility model uses DC brushless motor, direct current supply has the feature of voltage stabilization, the output characteristics that can make brushless electric machine 1 is more stable, uses unidirectional current can reduce the probability of happening of electric shock accidents simultaneously, provides necessary safety guarantee as workman.
Handleset includes battery controller 4, set of cells 5 and handle 6, battery controller 4 can use three core connecting lines or three-prong plug to be connected with set of cells 5, misloading is there is in order to avoid obscuring with electric machine controller 2, battery controller 4 in this utility model uses three-prong plug 41 to be connected with set of cells 5, three-prong plug 41 is arranged on battery controller 4, battery controller 4 and set of cells 5 are arranged on handle 6, and handle 6 is fixedly connected on the rear end of connecting tube 7 by screw 10.Battery controller 4 for managing the discharge scenario of set of cells 5, with reduce set of cells 5 energy effective consumption and effectively control set of cells 5 after to one's heart's content condition.
If set of cells 5 is fixedly mounted on handle 6, then after the electric quantity consumption of set of cells 5, need to move whole Gao Zhiju to be charged to power supply, handling process is the most laborious, add the labor intensity of workman, it is removably mounted on handle 6 for the set of cells 5 in this this utility model preferred embodiment, set of cells 5 can store enough electricity so that workman carries out cutting operation out of doors, in order to ensure power consumption when using, also it is ready for multiple set of cells 5 with standby, when a set of cells 5 is finished, available another replaces, save the time, its portability, superior dynamic trait more can allow Gao Zhiju adapt to complicated working environment.
Two core connecting lines 8 it are additionally provided with between battery controller 4 and electric machine controller 2, two core connecting lines 8 include positive lead and negative lead, battery controller 4 is used for controlling set of cells 5 provides electricity to brushless electric machine 2, in actual use, it is low that the required branch pruned has height to have, for higher branch, restriction due to connecting tube 7 length, it can not be modified by workman, very big inconvenience is brought to the operation of workman, for this, connecting tube 7 in this utility model is telescoping tube, telescoping tube includes big pipe and the tubule of mutual sheathing, tubule can slide along its length direction in big pipe, when needing to prune higher branch, tubule is pulled outside big pipe and positions, to extend the length of connecting tube 7;When needing to prune shorter branch, tubule pushed inside big pipe and positions, to shorten the length of connecting tube 7, operating relatively simple, and also increase the scope of Gao Zhiju pollard.
Owing to connecting tube 7 is telescoping tube, therefore when connecting tube 7 extends, two core connecting lines 8 can be pullled, when tension is excessive, two core connecting lines 8 can rupture, and for the generation of anti-phenomenon here, the company two core wiring 8 in this utility model is the two core spring connecting lines being coiled into form of springs, two core spring connecting lines can extend accordingly according to the length of connecting tube 7 and shorten, and do not interfere with its service life.Compared to existing technology, two core connecting lines in this utility model are possible not only to reduce manufacturing cost and molding difficulty, and are not susceptible to deformation, it is possible to reinstatement rapidly.
Two core connecting lines 8 both can be arranged on the outside of connecting tube 7, it is possible to is located in connecting tube 7.In preferred embodiment of the present utility model, two core connecting lines 8 are located in connecting tube 7, two core connecting lines 8 so can be avoided by the hook of branch or damaging of the external world, extend the service life of two core connecting lines 8, and the use making user is convenient.Two core spring connecting lines are less than the space shared by three core connecting lines, when being therefore located in connecting tube 7, reduce the requirement to connecting tube 7, effectively simplify the connecting line connecting Gao Zhiju two ends so that the overall structure of Gao Zhiju is simpler, and external form is more attractive in appearance.
Electric machine controller 2 in Gao Zhiju of the present utility model and brushless electric machine 1 are arranged on the front end of connecting tube 7, battery controller 4 and set of cells 5 are arranged on the rear end of connecting tube 7, electric machine controller 2 is to brushless electric machine 1 transmission of control signals, battery controller 4 is to set of cells 5 transmission of control signals, so design, substantially reduce the transmission range of control signal between electric machine controller 2 and brushless electric machine 1, and the transmission range of control signal between battery controller 4 and set of cells 5, compared to existing technology, the structure of the Gao Zhiju in this utility model has the benefit that 1, reduce the electromagnetic wave interference to control signal, enhance the intensity of signal, finally improve electric machine controller 2 for the control accuracy of brushless electric machine 1 and battery controller 4 for the control accuracy of set of cells 5;2, the control signal delivery time reduces, and shortens brushless electric machine 1 and the response time of set of cells 5, improves response speed.
Being also associated with one on battery controller 4 in this utility model preferred embodiment and bear the little signaling switch of electric current 9, signaling switch 9 can control the break-make situation of whole system, reduces the cost of Gao Zhiju.
