Description
The utility model relates to a kind of electric toy car.
Existing electric toy car all is to stir the certain angle of front vehicle wheel deflection by the move left and right of parts such as motor, decelerator drivening rod turning round when turning to, to realize what turning to of toy car turned round.Because this mechanism finishes by a series of mechanical mechanisms to drive the wheel turning action, and the parts in the mechanical mechanism especially the form accuracy and the dimension precision requirement of the gear mesh part in the decelerator is very high, just higher for the requirement of producing, so the expense of processing is also higher; In addition, because the engagement requirement between the gear can not have foreign material attached on the flank of tooth, thus toy car for the requirement on road surface also than higher, as meet foreign material and be bonded on the flank of tooth, very easily cause the stuck of decelerator and cause turning to malfunctioning fault, thereby the reliable in action of this mechanism not very high; And above-mentioned transmission mechanism weight is heavier, and shared volume is bigger, has influenced the design of product and the improvement of moulding.In addition, because the part in the mechanical driving device can cause wearing and tearing after use after a while, thereby reduce the sensitivity of transmission device and even cause and scrap.
The purpose of this utility model provides simple, the reliable in action of a kind of making, the wide accommodation of road pavement, and the less toy car transfer of volume.
The utility model comprises the stator of being made by magnetic material, the connecting rod that is installed in rotor, knuckle, connection rotor and knuckle in the stator, stator is the cylindrical shape of hollow, the inside of rotor is provided with the iron core of coiling lead, lead links to each other with power supply, knuckle is installed in rotation on the car body, and the axletree of wheel is installed on the knuckle.32, the finger 21 of rotor inserts in the hole 31 of connecting rod, the axletree of front-wheel is installed on the knuckle 4, knuckle 4 is provided with pivot 41 and trace 42, pivot 41 is installed in the installing hole on the car body, and can in installing hole, rotate, bearing pin on the trace 42 inserts in the hole 32 of interlinking lever end, when toy car turns to, the coil electricity of rotor 2 inside, the energising back produces magnetic field, because the direction in magnetic field is different with the direction in stator 1 magnetic field, under the effect in magnetic field, can produce a moment of torsion between stator 1 and the rotor 2, rotor 1 rotates under the effect of this moment of torsion, and rotor 1 drives knuckle 4 by connecting rod 3 and rotates, thereby the axletree rotation that knuckle 4 drives on it realizes that front-wheel rotates.Certainly, the utility model also can be transformed into the setting of stator and rotor opposite with embodiment, is about to coil and is installed in the stator, and rotor is made with magnetic material, can reach the effect identical with embodiment like this.Loam cake 8 be installed in stator 1 and rotor 2 above, each parts sealing of above-mentioned transfer can be fixed together.Be provided with back-moving spring 5 between rotor 2 and the car body, back-moving spring 5 is torsion springs, is installed on the car body, and the steel wire 51,52 of spring two ends is protruding, not on reference column 6, rotor 2 is provided with finger 23, and finger 23 inserts between the spring 5 outwardly directed steel wires 51,52, when rotor 2 rotates, finger 23 on the rotor 2 is stirred the steel wire 51,52 of spring, make spring 5 produce a torsion, rotor 2 is returned to original position under the effect of the torsion of spring 5 after coil stops to switch on.Two sides at the car body upper spring are provided with limiting plate 7, but the scope that the steel wire 51,52 of its restraining spring moves, thus define the angle that front-wheel rotates; Reference column 6 is provided with the fine setting knob, the fine setting knob comprises adjusting lever 61 and disk 62, car body is provided with porose 9, the fine setting knob is installed in rotation in the hole 9 of car body, reference column 6 is fixed on the disk 62 prejudicially, when adjusting the adjusting lever 61 of fine setting knob, reference column 6 drives stator 1 and rotates, to adjust the zero-bit position of front-wheel.In use,
The utility model is owing to adopted magnetic material stator of making and the rotor that has hot-wire coil, make the part of transfer reduce, and the structure of magnet and rotor, shape are all fairly simple, the precision and the dimensional requirement that do not have the gear in the mechanical driving device, make production technology and all become simple is installed, therefore can reduce production costs; Drive turning to of wheel because this transfer is the moment of torsion by magnetic force, so the dust on road surface and foreign material can not impact the malfunctioning phenomenon that can not rotate, so the reliability height of this device to transfer.In addition, therefore the utility model does not have the loss of friction, long service life owing to be not in contact with one another between magnet and the rotor.The utility model is because to have a volume little, and lightweight characteristics can make things convenient for the design of toy car product and the improvement of moulding.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural formula intention after the utility model removes loam cake;
Fig. 3 is the A-A cut-away view of Fig. 2.
The utility model is made up of car body, front-wheel, trailing wheel shown in 1-3 figure, be provided with transfer at front-wheel, this transfer comprises stator 1, rotor 2, connecting rod 3, knuckle 4, loam cake 8 and front-wheel, stator 1 is a columnar permanent magnet, the bottom surface of stator 1 is provided with a breach 11, car body is provided with reference column 6, and the breach 11 of stator is embedded on the reference column 6, can prevent the rotation of stator 1; Rotor 2 is installed in the inside of stator 1, the inside of rotor 2 is provided with iron core, the end face of iron core is exposed at the outside of rotor 2, be wound with coil on the iron core, after energising, can produce magnetic field, the center of rotor 2 is provided with rotating shaft 22, the bottom of car body is provided with porose, rotating shaft 22 is installed in the hole at the bottom of the car, rotor 2 can 22 rotate around the shaft, rotor 2 is provided with finger 21, the middle part of connecting rod 3 and two ends are provided with porose 31, when the needs toy car is turned, pass through control of remote controller, make the coil electricity of rotor 2, coil after the energising produces a magnetic field, because the setting in this magnetic field is different with the magnetic direction of the stator of being made by magnetic material 1, therefore will produce a moment of torsion, under the effect of moment of torsion, post 6 is fixing because stator 1 is positioned, not rotatable, therefore can only be that rotor 2 rotates, the bearing pin 21 on the rotor 2 drives knuckle 4 by connecting rod 3 and rotates, and the front-wheel that knuckle 4 drives on it rotates, thereby realized the turning of toy car, after toy car forwards preposition to, can disconnect by the power supply of remote controller rotor, the magnetic field of the rotor 2 of outage disappears, and there is not moment of torsion between the stator 1, rotor 2 has recovered original position under the effect of back-moving spring 5, make toy car continue to keep straight on.
