DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] For example, Figures 1-5As shown: a new type of simulation road roller toy, including the car body 1, the car body 1 front end swing set with a roller frame 2 for installing roller 3 as the car head, when the car body 1 because of the wheel 101 rotation and forward, the roller 3 will also be rolling, to simulate the real road roller compaction action.

[0024] Further, the above-mentioned car body 1 when set with a steering rudder 4 for controlling the roller frame 2 to achieve steering action, the roller frame 2 steering can drive the car body 1 with the steering, change the path. As Figure 2 As shown, the output end of the steering rudder 4 is equipped with actuating arm 401, swing set in the car body 1 front end of the roller frame 2 is hinged with connecting arm 201 on both sides of itself, the other end of the connecting arm 201 and actuating arm 401 are hinged; when the actuating arm 401 because of the steering rudder 4 drive left / right rotation, can be through two connecting arm 201 corresponding to pull the roller frame 2 steering, the roller frame 2 as the car head steering, can also drive the car body 1 steering, so as to realize the steering action of the whole road roller toy.

[0025] Specifically, in order to prevent the car body 1 steering drift problem, the car body 1 inside also corresponding to the wheel 101 is provided with differential mechanism 5, the differential mechanism 5 includes the split through the left and right shell of the differential box 501, the differential box 501 is formed with the outer teeth 511, a differential box motor 502 is engaged with the differential box 501 through the differential box gear 512, the differential box 501 is internally arranged with three planetary gears 503 in the form of ring, three planetary gears 503 are commonly installed on the differential box 501 embedded in a gear frame 521, the axle 111 of the wheel 101 on both sides of the car body 1 passes through the differential box 501, and the side gear 504 is formed at the end, the side gear 504 of the two axle 111 is engaged with each other through the planetary gear 503. The principle of the differential mechanism 5 is roughly the same as the real differential, that is, the power transmitted by the differential box motor 502 can be distributed to the two wheels 101 at different speeds, preventing the wheels 101 from slipping when the car body 1 turns.

[0026] Further, the above-mentioned roller frame 2 in the front end is also hinged with a group of push shovel 6, the push shovel 6 can be pulled by the telescopic rod 7 to swing up and down relative to the roller frame 2 to realize lifting. As Figure 3As shown, the telescopic rod 7 includes an inner rod 701 and an outer rod 702, the outer rod 702 is fixed on a box arranged on the drum frame 2, the inner rod 701 is movably sleeved with the outer rod 702 and is internally threaded, a screw rod 703 driven to rotate by a screw rod motor 704 is threadedly connected with the inner rod 701, so that the inner rod 701 can be driven to extend and retract relative to the outer rod 702, meanwhile, the push shovel 6 is fixed with a hinge joint 601, and the end of the inner rod 701 has a cross rod 711 penetrating through the hinge joint 601, when the inner rod 701 extends and retracts, the push shovel 6 can be correspondingly swung up and down through cooperation of the cross rod 711 and the hinge joint 601.

[0027] Specifically, the end of the screw rod 703 is inserted with a cap gear 713 with a protrusion, a plug pin 723 penetrates through the protrusion to fixedly combine the screw rod 703 and the cap gear 713 with each other, a plurality of transition gears 705 arranged in the box are located between the screw rod motor 704 and the cap gear 713, and are used to cooperate with the screw rod motor 704 to drive the screw rod 703 to rotate; the above fixing mode is adopted because if the screw rod 703 and the cap gear 713 are directly tightly inserted, the connection part of the two is prone to wear after a period of time, since the connection part is relatively large in stress when the telescopic rod 7 extends and retracts, the wear is likely to cause the screw rod 703 to be separated from the cap gear 713 or even broken, and the damage of the structure will make the toy unable to continue to be used, the plug pin type fixed connection can avoid the problem to a certain extent, so as to improve the service life of the toy.

[0028] Further, the drum 3 is further formed with an inner cavity, an eccentric vibration motor 301 is fixed in the inner cavity, and a counterweight 311 is further arranged on the output shaft of the vibration motor 301, the vibration motor 301 can drive the drum 3 to vibrate, improve the fidelity of the drum 3, and make the drum 3 closer to the drum in the real world.

[0029] Further, the steering rudder 4, the vibration motor 301, the gear box motor 502 and the screw rod motor 704 are all controlled by a circuit board arranged in the vehicle body 1, and the player controls the road roller toy to realize various actions through an external remote controller.

[0030] The action mode of the design is mainly realized by driving the vehicle body to move forward by the gear box motor, when the steering rudder drives the drum frame to turn, the vehicle body itself will also turn, and the differential mechanism is used to prevent the wheels from slipping.
