Automatic mowerTechnical field
The utility model relates to technical field of garden, and in particular to a kind of automatic mower.
Background technique
Currently, the clock circuit of the mainboard of grass trimmer machine is powered by button cell, button cell restricted lifetime, it is fixed to needPhase replacement, brings inconvenience to product user.
Utility model content
The main purpose of the utility model is to provide a kind of automatic mowers, to solve automatic mower in the prior artOn button cell restricted lifetime need to regularly replace and lead to inconvenient problem.
To achieve the goals above, the utility model provides a kind of automatic mower, comprising: shell, is cut mobile moduleModule, energy module and control module are cut, mobile module, cutting module, energy module and control module are installed on shell,Energy module includes battery pack, and battery pack is the movement and work power supply of automatic mower；Control module controls mobile module bandDynamic automatic mower is mobile, and controls cutting module mowing, and control module includes clock circuit and conversion circuit, conversion circuit pointIt is not electrically connected with clock circuit, battery pack, so that battery pack is clock circuit power supply by conversion circuit.
Further, conversion circuit is direct-current voltage reducing circuit.
Further, automatic mower further includes mainboard, and clock circuit and direct-current voltage reducing circuit are arranged on mainboard.
Further, the output voltage of battery pack is 18V.
Further, the supply voltage of clock circuit is 3.3V.
Technical solutions of the utility model, have the advantages that use battery pack by conversion circuit for clock circuit power supply,The power consumption of clock circuit is minimum for battery pack, and battery pack is that have prevented button cell regular for the power supply mode of clock circuitThe inconvenience of replacement overcomes the periodic replacement problem of machine mainboard button cell in the prior art, brings to product userGreat convenience.
Detailed description of the invention
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior artSpecific embodiment or attached drawing needed to be used in the description of the prior art are briefly described, it should be apparent that, it is described belowIn attached drawing be that some embodiments of the utility model are not paying creativeness for those of ordinary skill in the artUnder the premise of labour, it is also possible to obtain other drawings based on these drawings.
Fig. 1 shows the schematic diagram of the embodiment of automatic mower according to the present utility model.
Description of symbols:
10, clock circuit；20, conversion circuit；30, battery pack.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that describedEmbodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originallyField those of ordinary skill every other embodiment obtained without making creative work belongs to practicalNovel protected range.
As shown in Figure 1, the automatic mower of the present embodiment include: shell, mobile module, cutting module, energy module andControl module, mobile module, cutting module, energy module and control module are installed on shell, and mobile module includes wheel groupAnd drive motor, drive motor driving wheel group is mobile so that automatic mower is mobile；Cutting module include blade and cutting motor,Blade is installed on housing bottom, and cutting motor driving slice rotation is to mow；Energy module includes battery pack 30, and battery pack 30 isThe movement and work power supply of automatic mower；Control module is electrically connected with mobile module, cutting module, energy module, controls mouldBlock controls mobile module and drives automatic mower movement, and controls cutting module mowing, and control module includes 10 He of clock circuitConversion circuit 20, conversion circuit 20 is electrically connected with clock circuit 10, battery pack 30 respectively, so that battery pack 30 passes through conversion circuit20 power for clock circuit 10.
Using the automatic mower of the present embodiment, use battery pack 30 by conversion circuit 20 for the power supply of clock circuit 10,The power consumption of clock circuit 10 is minimum for battery pack 30, and battery pack 30 is that the power supply mode of clock circuit 10 has prevented buttonThe inconvenience of battery periodic replacement, overcomes the periodic replacement problem of machine mainboard button cell in the prior art, uses to productFamily brings great convenience.
In the present embodiment, clock circuit can be the clock chip of integrated circuit composition.Conversion circuit can beThe conversion chip that integrated circuit is constituted.
In the present embodiment, conversion circuit 20 is direct-current voltage reducing circuit.The output voltage of battery pack 30 is than clock circuit 10Supply voltage it is big, be depressured by direct-current voltage reducing circuit, meet the power demands of clock circuit 10.
In the present embodiment, the output voltage of battery pack 30 is 18V.Battery pack 30 is not limited to this, and is needed according to specificSituation carries out the battery pack that selection has suitable output voltage.The supply voltage of clock circuit 10 is 3.3V.Clock circuit 10It is also not limited to this, the clock circuit 10 with suitable supply voltage can be selected as the case may be.
In the present embodiment, automatic mower further includes mainboard, and clock circuit 10 and direct-current voltage reducing circuit are arranged at masterOn plate.Mainboard plays the role of fixed clock circuit 10 and direct-current voltage reducing circuit.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is rightFor those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation orIt changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation orIt changes among the protection scope created still in the utility model.
