Abstract

The utility model relates to a driving mechanism for a rotary cycle, which comprises a casing, a micro motor, transmission gears, a traveling gear cluster, a controlling rod gear cluster, a movable wheel rod, a controlling rod half wheel, a lifting rod, a pull rod spring, a driving wheel, a supporting point, etc. The controlling rod gear cluster is matched with the pull rod spring to control the action of the movable wheel rod and enables the front end of the cycle body to leave the ground; when the controlling rod gear cluster is rotated, the traveling gear cluster drives the cycle body to carry out forward and backward movements by the lifting and descending the lifting rod simultaneously. Toy cycles formed from the utility model can make conversions of moving modes, such as moving forward or backward, moving forward or backward when the cycle body is inclined, and rotating 360DEG when the cycle body is erected on the ground, etc. The interesting of the toy cycle is enhanced.

Description

The transmission mechanism of rotation car

The utility model belongs to the transmission mechanism of toy car.

Forms such as can only advancing, retreat, turn round more than the toy car walking manner in the prior art, interest is not high.

The utility model purpose is to provide a kind of transmission mechanism that rotates car, and this transmission mechanism can order about all conversion that toy car is realized walking manner, does rotation, skewed walking or the like as a upright front of the car.

The axle of the transmission mechanism of rotation car by micro machine cogs and drives the walking gear group simultaneously and control bar gear train rotates, control bar gear train cooperates pull-rod spring control to be arranged on that a movable wheel bar orders about the vehicle body walking manner and does continuous transformations such as advancing, tilt to advance, uprightly rotate, retreat along its movement locus displacement in activity wheel bar evolution below the car abdomen.Improve children greatly to the liking of toy car, strengthen the interest of playing car.

Below by drawings and Examples the utility model is described specifically.

Fig. 1 is the utility model vertical structure cutaway view.

Fig. 2 is the utility model transversary cutaway view.

Fig. 3 is that the utility model control bar is partly taken turns a kind of configuration diagram.

Fig. 4 is the utility model elevating lever installation diagram.

Shown in accompanying drawing, the transmission mechanism of rotation car is by casing 1, micro machine 2, and travelling gear 3, walking gear group 4, control bar gear train 5, movable wheel bar 6, the control bar partly takes turns 7, elevating lever 8, pull-rod spring 9, trailing wheel 10, fulcrum 11 members such as grade are formed.Above-mentioned walking gear group 4 is by in-line gears 41,42, double-

layer gear

43,44,45, and in-

line gears

46,47, wheel sleeve gear 48 is formed, travelling gear 3 engagements on its middle gear 41 and the motor shaft, wheel sleeve gear 48 is coaxial with trailing wheel 10.Above-mentioned control bar gear train 5 is by double-

layer gear

51,52,53,54, and

coaxial tooth axle

55,56 is controlled bar gear 57 and formed, and wherein double-layer gear 51 and travelling gear 3 engagements are controlled the long projection 571 and the short projection 572 that are shaped on symmetrical dress on bar gear 57 1 sides.Movable wheel bar 6 is by wheel bar 61, drive block 62 loose joints form, movable wheel bar 6 is positioned at the lower abdomen of car, drive block 62 is upside-down triangle shape, be actively socketed on the casing axle with an angle, drive block 62 movable controlled bar gear 57 controls, wheel bar 61 also is provided with a projection 611 with contact 612 end side surface of drive block 62, this projection 611 is movable and is sleeved in the shell guide groove 11 that bottom of shell extends, and wheel bar 61 is made telescopic displacement along guide groove 11 and contact 612.Pull-rod spring 9 one ends are fixed on the drive block 62 of movable wheel bar 6, and an end is sleeved on the casing axle.Above-mentioned control bar partly takes turns 7 as shown in Figure 3, and this is partly taken turns 7 and is fixed on 57 of the control bar gears.Elevating lever 8 one ends are enclosed between the in-line gears 41,42 on the axle, the other end be movable end 81 kinks on the axle of casing 1, elevating lever 8 lower ends are with spring 83.Elevating lever 8 movable ends 81 have one partly to take turns the boss 82 that 7 inclined-planes 71 match with the control bar, and during installation, elevating lever boss 82 just is positioned at the control bar and partly takes turns the tangent position of movement locus face, promptly by rotate the control bar partly take turns 7 can be with elevating lever 8 jack-up upwards.Its installation diagram as shown in Figure 4.Fulcrum 11 makes in body rear end central authorities.

The utility model is implemented action can following several motion mode:

Shown in accompanying drawing, when the power-on switch, when making micro machine 2 drive travelling gear 3 rotations, travelling gear 3 drives walking gear group 4 simultaneously and control bar gear train 5 rotates.

First motion state, car advances.The gear 41,42 that travelling gear 3 drives walking gear group 4 rotates, and drives double-layer gear 44 by 42, by 44 drive double-layer gears 45, by 45 driven gears 46, at last by giving wheel sleeve gear 48 with 47 transmissions of 46 in-line gears, coaxial because of trailing wheel 10 with gear 48, be in the walking states that advances so rotate car.

Second kind of motion state skewedly advanced, rotated.Travelling gear 3 is the also double-layer gear 51 of transmission control bar gear train 5 successively simultaneously, 52,53,54,55, slow down, because of on 56 of the gears buffer spring 561 is housed, so when gear 56 travelling gears 57, when control bar gear 57 is gently done the up time rotation, drive block 62 noses of the long projection 571 promotion activities wheel bar 6 on the control bar gear 57, drive block 62 is slowly descended and drive motion bar 61 front end slowly and prop up and overhead be skewed and advance vehicle body, when drive block 62 noses withstand on long projection 571 protruding tops on the control bar gear 57 vehicle body be erected in planar, fulcrum 11 lands, this sub-car also is in forward travel state, because of trailing wheel 10 is driving wheels, so the rotation car is done clockwise 360 ° of rotations around fulcrum 11.When the long projection 571 of control bar gear 57 turns over the projection of drive block 62, drive block 62 drive activity under control bar spring 9 active forces is taken turns bar 6 times in original position, is concealed in the bottom surface of casing 1.

The third motion state: car is skewed to be retreated.When control bar gear 57 drive activities wheel bar 6 lifts vehicle body and rotates, control bar gear 57 drives coaxial rotation and partly takes turns 7 and rotate, rotate partly take turns 7 inclined-plane 71 slowly with elevating lever 8 jack-up, thereby drive in-line gears 41,42 rise simultaneously, make gear 42 break away from gear 44 and gear 43 engagements, by gear 43 travelling gears 44, make gear 45 again, 46,47,48 equal counter-rotation, trailing wheel 10 are and retreat walking.Because of driving wheel 10 retreats walking suddenly, vehicle body falls down under action of inertia.Meanwhile, the short projection 572 of control bar gear 57 is the drive block projection of promotion activity wheel bar 6 just, and drive block 62 drives motion bar 61 again with the body structure top overhead, makes vehicle body be in heeling condition and retreats.After control bar gear 57 short projections 572 turned over the drive block projection, movable wheel bar 6 was regained original position again under the effect of control bar extension spring 9.Body structure falls, and car is parallel to ground.Partly take turns 7 and rotate along with the control bar, elevating lever 8 boss 82 break away from partly takes turns 7, and elevating lever 8 is regained original position under self spring 83 effect, and this moment, gear 42 broke away from gear 43 and gear 44 engagements again, and car recovers the walking of promptly advancing of first kind of motion state.

As the conversion of present embodiment, can also below the fulcrum 11 of vehicle body, one dismountable moving fulcrum 12 be set near driving wheel 10 1 end positions, allow the rotation car do the motion of less movement locus face to cooperate driving wheel 10, adapt to and play littlely.
