Description

A kind of remote-controlled toy vehicle transfer that is adapted to multiple road surface

The utility model relates to a kind of electric remote control toy car.

At present, the electric remote control toy car that is occurred on the market, the transfer that its control turns to is fixing nonadjustable, make the toy car front-wheel can only rotate a fixing angle, the user can't according to oneself use habit or adjust the rotational angle of front-wheel according to the variation of environment, so its suitability is relatively poor, and when environmental change, because the road surface is for the frictional force difference of wheel, as sand ground or comparatively during the heavy road face, bigger with the frictional force of wheel, the required moment of torsion of turning is also bigger, and on comparatively smooth road surface, the frictional force on wheel and road surface is less, required moment of torsion is also less, and existing wheel makes to be difficult to control because of not regulating the size of control wheel torque.And the transfer on the toy car is not provided with protection mechanism, all is rigidly connected between each parts; in case be subjected to the impact or the collision of external force; parts on the toy car very easily damage, and when serious toy car are scrapped, and cause material and loss economically.

The purpose of this utility model provides and a kind ofly turns to flexibly, reliable in action, and the remote-controlled toy vehicle transfer that is adapted to multiple road surface at adjustable whole deflecting roller bundle angle when turning to.

Another one purpose of the present utility model provides a kind ofly can avoid the toy car transfer that parts are damaged when toy car is impacted and collide.

The utility model comprise rocking arm, preceding wheeling support and be connected rocking arm and before the connecting rod of wheeling support, rocking arm links to each other with actuating unit, preceding wheeling support is installed in rotation on the chassis of toy car, described connecting rod is an adjustable connecting-rod; Described rocking arm and preceding wheeling support are provided with some installing holes.

The utility model is owing to be arranged to adjustable link with the connecting rod on the transfer, and rocking arm and preceding wheeling support are provided with a plurality of installing holes, make the bundle angle of transfer and the moment of torsion that is transmitted to regulate, so that toy car can adapt to different road surfaces, and it is more flexible that toy car is handled.The utility model has increased buffer unit on the rocking arm of transfer, make toy car when meeting external impacts or barrier, can protect the parts on the transfer, and it can be damaged.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is the scheme of installation of the utility model on toy car;

Fig. 2 is a parts schematic diagram of the present utility model;

Fig. 3 is a structural representation of the present utility model;

Fig. 4 is a rocker structure schematic diagram of the present utility model;

Fig. 5 is the structural representation of rolling disc of the present utility model;

Fig. 6 is the structural representation of rolling disc of the present utility model.

As shown in Figure 1, transfer of the present utility model is arranged on the front-wheel of toy car, comprise actuating unit 1, buffer gear 2, adjustable connecting-rod 3, preceding wheeling support 4 and back shaft, buffer gear 2 links to each other with the output shaft 11 of actuating unit, and by wheeling support 4 rotations before adjustable connecting-rod 3 drives, on the wheeling support 4, front-wheel rotated under the drive of preceding wheeling support 4 before front-wheel was installed in, thereby realized turning to of toy car.Shown in Fig. 2,3, adjustable connecting-rod 3 is made up of connector 32 that is arranged on two ends and connecting rod 31, and its two ends connector 32 links to each other with preceding wheeling support 4 with rocking arm 23 respectively rotationally; One end of connector 32 is provided with the hole 322 that can be used for connecting rocking arm 32 or preceding wheeling support 4, the other end is provided with screwed endoporus 321, two ends of connecting rod 31 are provided with external screw thread 311, be screwed into respectively in the internal thread 321 of two connectors, be screwed into the length that the length of connector 32 is regulated adjustable connecting-rod 3 by regulating connecting rod 31; Diverse location at rocking arm 23 and preceding wheeling support 4 is provided with several installing holes 233,41, the length by regulating adjustable connecting-rod 3 and the position of conversion installing hole 233,41 just can change bundle angle and the actuating unit 1 of front-wheel when turning and act on moment of torsion on the front-wheel.When the road surface was comparatively smooth, moment of torsion required during turning was less, and it is less that the length of adjustable connecting-rod 3 can be regulated, at this moment the bundle angle of front-wheel when turning can become bigger, the moment of torsion that actuating unit 1 acts on the front-wheel is less; When the road surface was comparatively coarse, it is less that adjustable connecting-rod 3 can be regulated, at this moment the bundle angle of front-wheel when turning can become less, the moment of torsion that actuating unit 1 acts on the front-wheel is bigger, can make front-wheel can overcome the frictional force on wheel and ground, is turned easily.It is to link to each other with cheese head screw 5 that adjustable connecting-rod 3 reaches between the preceding wheeling support 4 with rocking arm 23, one end of cheese head screw 5 is provided with screw thread, the other end 51 is arranged to a sphere, in the endoporus 322 of connector, be provided with the curved surface that can match with the ball-shaped end 51 of cheese head screw, the end 51 of cheese head screw is installed in the endoporus 322 of connector, and the two can relatively rotate.Buffer gear 2 comprises rolling disc 21, bolster 22 and the rocking arm 23 that links to each other with actuating unit output shaft 11 as described in shown in Fig. 2-6, bolster is the elasticity ring set that has opening 221, the endoporus of rolling disc is provided with spline 213, be used for linking to each other, can make output shaft 11 drive rolling disc 21 and rotate together with the output shaft 11 of actuating unit; One side of rolling disc 21 and rocking arm 23 is respectively arranged with and the corresponding step cutting pattern 211,213 of bolster 22 internal diameters, and the arranged outside of described step 211,213 has a key bar 212,232; Have an opening 221 on the described bolster 22, the width of opening 221 can be slightly less than the width of above-mentioned key bar 212,232, make that key bar 212,232 inserts openings 221 after, the elasticity of bolster 22 can make rolling disc 21 and the rocking arm 23 can be relative not loosening; The key bar 212,232 of rolling disc and rocking arm is from two side intercalations of bolster 22 opening 221 at bolster, and simultaneously, the step 211,232 on rolling disc and the rocking arm also socket-connects with bolster 22; When actuating unit 1 rotated, output shaft 11 drove rolling disc 21 and rotates, and rolling disc 21 drives rocking arm 23 by bolster 22 and rotates; Rotate when being obstructed when front-wheel meets obstacle, the moment of torsion between rolling disc 21 and the rocking arm 23 increases, and the opening 221 of bolster opens, and relatively rotates between rolling disc 21 and the rocking arm 23, can protect the parts of transfer can not damage like this; After removal of obstacle, the opening 221 of bolster returns to the original form again under the elastic reaction of bolster 22.Back shaft 6 is fixed on the chassis of toy car; Before wheeling support 4 be provided with porosely 42, be installed in rotation on the back shaft 6 by wheeling supports 4 before this hole 42; Preceding wheeling support 4 is provided with the hole 43 that front axle can be installed, and front axle 43 is installed in rotation on the preceding wheeling support 4.When toy car need be turned, rotate by remote controller steering maneuver mechanism 1, under the drive of actuating unit 1, wheeling support 4 rotated around back shaft 6 before buffering rocking arm 2 drove by adjustable connecting-rod 3, thereby drove the rotation of front-wheel.
