For this reason, Chinese utility model patent ZL200720034364.7 discloses " a kind of easy starting mechanism of general gasoline engines ", and it comprises the starter cover cap, is provided with rotating shaft in the starter cover cap, and this rotating shaft is connected with backrush mechanism; Described backrush mechanism comprises return wind spring, starter pulley, accumulation of energy wind spring and the pawl disk that is set in successively in the rotating shaft.Wherein, an end of return wind spring is connected on the starter cover cap, and its other end is connected on the starter pulley; One end of accumulation of energy wind spring is connected on the starter pulley, and its other end is connected with pawl disk; Ratchet and ratchet torsion spring are installed on the pawl disk; Ratchet outwards opens under the effect of ratchet torsion spring, one side of back ratchet is enclosed within the outside of ratchet and ratchet torsion spring and is connected with pawl disk, bolt pin passes behind above-mentioned each assembly with rotating shaft in the starter cover cap and is connected, above-mentioned each assembly is installed on the starter cover cap, and the opposite side of back ratchet connects the rotary seat assembly.The starting of the starting mechanism of this petrol engine is steady, laborsaving, and the counter-rotating can prevent to start the time.But it still needs manual starting, still needs bigger starting pulling force.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation at prior art provides a kind of manually electric starting structure of the general gasoline engines of pulling that do not need.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the electric starting structure of this general gasoline engines, comprise the starting component that is connected with the driving mechanism of this petrol engine, it is characterized in that described starting component comprises power supply, the motor that is electrically connected with power supply and by described motor-driven transmitting assemblies, described transmitting assemblies connects described driving mechanism.
Describedly can be intermeshing one group of gear to transmitting assemblies, preferably, consider the turning to of laborsaving and transmission direction of transmission, described transmitting assemblies can comprise first gear train and second gear train; Wherein, described first gear train comprises motor gear that is arranged on the described motor output shaft and the gear broad in the middle that is meshed with this motor gear; Described second gear train comprises and the intermediate speed pinion of described gear coaxial rotation broad in the middle and the driving gear that is meshed with this intermediate speed pinion; Described driving gear connects described driving mechanism.
Certainly, also can adopt other non-geared drive structure, but comparatively speaking, the gear drive structure that the utility model adopted is simpler, employed accessory has more versatility.
The tools structure that described transmitting assemblies can be used this petrol engine is set directly in the housing of this instrument, perhaps is attached to outside the housing of this instrument.Preferably, the gripping when operating for convenience, described transmitting assemblies and described driving mechanism can be arranged in the housing; The fuel tank of described petrol engine has a reentrant part, and described housing is arranged in the reentrant part of described fuel tank.
Driving mechanism in above-mentioned each scheme can use the various driving structure of existing general gasoline engines, preferably, cooperates the described driving mechanism of the electric starting structure in the utility model can comprise torsion spring, ratchet and pawl disk; One end of wherein said torsion spring connects described driving gear, and the other end of torsion spring connects described ratchet, and described ratchet drives and connects described pawl disk.Simple in structure, the transmission of power is good.
For convenience gasoline joins in the fuel tank, and the oblique evagination of inlet that prevents described fuel tank is in the upper surface of fuel tank.
Compared with prior art, the utility model adopts the motor driving driving mechanism to start driving mechanism, thereby starting up gasoline engine has been avoided manual pulling fully, the counter-rotating when starting steadily also can effectively prevent to start; This electricity starting structure also has the good characteristics of simple in structure, used accessory versatility simultaneously.
