The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
As shown in Figure 1 to Figure 3, a kind of brake device of electric chain saw, the chain saw componet including upside brake assemblies and downside,
Be characterized in that: the brake assemblies include brake baffle 1, hinge component 2, switch shifting block 5, roller switch 3, controller 20, stop
Vehicle return piece 7, brake ribbon 15, connecting rod 16 and tension spring 18;On the shell, brake 1 side of baffle passes through solid 1 set of the brake baffle
The left joint pin 19 being scheduled on the shell of right side rotates together with the left end of connecting rod 16, and the other side is rotatably connected on left side by bolt
On shell;The hinge component 2 and switch shifting block 5 are fixed on the right joint pin 6 on the shell of right side together, and together with connecting rod 16
Right end rotation;2 upper end of hinge component is connected with tension spring 18, and 2 lower end of hinge component is connected with brake ribbon 15;It is described
Tension spring 18 is fixed on chain saw shell by the second connector 17;Gasket 14, the first connector 13 are covered on the brake ribbon 15
Brake ribbon 15 is fixed on chain saw shell across gasket 14, and brake ribbon 15 is stuck in one by pin 12 and the first connector 13
It rises;The setting of brake return piece 7 is fixed on the shell of right side in brake 1 lower end of baffle, the arcwall face for the return piece 7 that brakes
Withstand on brake 1 lower end of baffle;The controller 20 is fixed on housings;
The chain saw componet includes guide plate 4, chain 21, brushless motor 8, sprocket wheel baffle 10, clutch disk 11;The clutch disk
11 are arranged on brushless motor 8, and outside is provided with sprocket wheel baffle 10;The brushless motor 8 by driving clutch disk 11, allow from
Dish 11 is closed to rotate with movable sprocket;The brushless motor 8 is electrically connected with controller 20;The guide plate 4 is assemblied on sprocket wheel, guide plate 4
It is upper that chain 21 is housed.First connector 13 uses cross recessed countersunk head tapping screw, and second connector 17 uses cross
Coiled hair band pads tapping screw.
Wherein, the switch shifting block 5 and the idler wheel of the roller switch 3 mutually resist, and roller switch 3 is electrically connected with controller 20
It connects.
Wherein, the right joint pin 6 is connected to the middle position of hinge component 2, and hinge component 2 is with right joint pin when braking
Centered on rotate.
Wherein, the brake ribbon 15 is closely enclosed in 11 periphery of clutch disk.
In working condition, the brake baffle 1 resists mutually the present invention with hinge component 2, is held and is drawn by hinge component 2
Spring 18 makes the tension spring 18 in tensional state.
As shown in Fig. 2, the present invention pushes brake baffle when braking, by arrow direction in figure, make baffle pine of braking
Hinge component is opened, hinge component is shunk the pulling force replied by tension spring and pulls, rotates counterclockwise, make the lower end of hinge component
Hook pulls brake ribbon, firmly the clutch disk on anchor ear brushless motor, carries out mechanical brake.While mechanical brake, due to hinge
Chain component rotates and toggle switch shifting block, and the idler wheel of switch shifting block rotation roller switch disconnects the roller switch of closure.Control
After device receives the information of circuit disconnection, issues instruction and drive lower bridge to open the triple line of brushless motor, keep triple line short-circuit, and
Generating opposite force prevents motor from rotating.To control brushless motor by controller, then by brushless motor driving clutch disk brake chain
Wheel carries out electric brake.The mode of electric brake after first mechanical brake, compared to simple mechanical brake, reduce brake ribbon and
The specific gravity braked between clutch disk by friction, reduces the abrasion between brake ribbon and clutch disk, extends chain saw
Service life.
Tension spring in the present invention be for braking, rather than for make brake baffle movement after reset.When braking, need to only it push away
Dynamic brake baffle is allowed to separate with hinge component, brake ribbon can be pulled to be braked by the pulling force that tension spring contraction is replied,
It is not to make the band brake that brakes with Manual-pushing brake baffle, it is very convenient laborsaving.
The setting of brake return piece 7 is fixed on the shell of right side in brake 1 lower end of baffle, the arc for the return piece 7 that brakes
Shape face withstands on brake 1 lower end of baffle.The arcwall face of brake return piece withstands on always brake baffle lower end, and brake return piece and chain
Saw shell phase is withstood.When pushing brake baffle, brake return sector-meeting generates screen resilience to brake baffle, plays to brake baffle
Buffering and return effect.
It should be noted that brushless motor 8 and controller 20 are to realize controller by way of being electrically connected in the present invention
Control to brushless motor.Wherein, electrical connection can be the conventional electricity such as power supply line connection or inner lead connection between two components
Road connection type.Since the circuit communication between component is the prior art, this is repeated no more.
In conclusion the invention can first carry out mechanical brake, then electric brake is carried out, can only led to compared to existing chain saw
It crossing manual operation and carries out emergency mechanical brake, the present invention can weaken the abrasion between brake ribbon and clutch disk using electric brake,
To extend the service life of brake gear in chain saw.And when braking, brake baffle is pushed to be allowed to separate with hinge component, according to
Pull brake ribbon that braking can be realized by tension spring, it is very convenient laborsaving.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope.
