Described differential structural mechanism comprises three grades of gear wheels, umbrella shape gear wheel, turning cylinder and differential wheel cap, and three grades of gear wheels and secondary gear wheel are connected with a joggle, and the umbrella shape gear wheel is embedded on the framework of three grades of gear wheel inside, can freely rotate along self central shaft;
Be fixed on after described rotating drive mechanism, rotation interlinked mechanism and the box of tricks combination assembling and protect in the case lid.
Described rotary axle box band hypotenuse gear wheel, and fixing back band hypotenuse gear wheel can just be buckled on the umbrella shape gear wheel.
Described turning cylinder is made up of first turning cylinder and second turning cylinder; The differential wheel cap is made up of left differential wheel cap and right differential wheel cap, left side differential wheel cap is connected with the both sides of three grades of gear wheels respectively with right differential wheel cap, first turning cylinder is connected with three grades of gear wheels by left differential wheel cap, and second turning cylinder is connected with three grades of gear wheels by right differential wheel cap.
Described guarantor's case lid is by last guarantor's case lid and protect down case lid and forms, on to protect case lid be to be connected by screw with following guarantor's case lid.
The utility model is broken through traditional rear drive mode, increases by one group of box of tricks, normally walks when making car not run into barrier, and another side is rotated further Yi Bian can allow to stop when running into barrier, thereby loop current can sharply not increased.Compared with prior art, the utility model structure fault rate that can reduce the remote-controlled toy vehicle wiring board can prolong the service life of motor again.

Wherein, 1 is that motor, 2 is that one-level gear wheel, 3 is that secondary gear wheel, 4 is that three grades of gear wheels, 5 are that umbrella shape gear wheel, 61 is that left differential wheel cap, 62 is that left differential wheel cap, 71 is that first turning cylinder, 72 is that second turning cylinder, 81 is that last guarantor's case lid and 82 is last guarantor's case lid.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
A kind of remote-controlled toy vehicle rear drive configuration, as depicted in figs. 1 and 2, comprise rotating drive mechanism, rotate interlinked mechanism and box of tricks, described rotating drive mechanism comprises control circuit board and motor 1, control circuit board is fixed on the vehicle body main body, and control circuit board and motor 1 are connected by lead.Described rotation interlinked mechanism comprises one-level gear wheel 2 and secondary tooth 3, and one-level gear wheel 2 is enclosed within on the output shaft of motor 1, and secondary tooth 3 is connected with a joggle with one-level gear wheel 2.Described differential structural mechanism comprises three grades of gear wheels 4, umbrella shape gear wheel 5, turning cylinder and differential wheel cap, and three grades of gear wheels 4 are connected with a joggle with secondary gear wheel 3, and umbrella shape gear wheel 5 is embedded on the framework of three grades of gear wheel 4 inside, can freely rotate along self central shaft.Rotary axle box band hypotenuse gear wheel, and fixing back band hypotenuse gear wheel can just be buckled on the umbrella shape gear wheel.Turning cylinder is made up of first turning cylinder 71 and second turning cylinder 72; The differential wheel cap is made up of left differential wheel cap 61 and right differential wheel cap 62, left side differential wheel cap 61 is connected with the both sides of three grades of gear wheels 4 respectively with right differential wheel cap 62, first turning cylinder 71 is connected with three grades of gear wheels 4 by left differential wheel cap 61, and second turning cylinder 72 is connected with three grades of gear wheels 4 by right differential wheel cap 62.
Be fixed on after described rotating drive mechanism, rotation interlinked mechanism and the box of tricks combination and protect in the case lid.Protect case lid by last guarantor's case lid 81 with protect case lid 82 down and forms, on to protect case lid 81 can be to be connected by screw with following guarantor's case lid 82.
Rotated by wiring board drive motors 1 when car is normally walked, motor 1 directly drives wheel and rotates by one-level gear wheel 2, secondary gear wheel 3 and three grades of gear wheel 4 transmission gear shifts.When car is run into barrier, the resistance of car the right and left wheel passes to respectively on second turning cylinder 72 on first turning cylinder 71 on the left side or the right, because the resistance on both sides is different big, motor 1 rotates by one-level gear wheel 2, after secondary gear wheel 3 speed changes power is applied on the umbrella shape gear wheel 5, umbrella shape gear wheel 5 and then power passed to first turning cylinder 71 on the left side or second turning cylinder 72 on the right, to be rotated further by the less relatively one side wheel of resistance, will slow rotation or stop operating and be subjected to the relatively large wheel of resistance, even the wheel motor that stops operating still can be rotated further so on one side, loop current just can sharply not increase yet, thereby has not only reduced the fault rate of wiring board but also prolonged service life of motor.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
