[0001] The utility model relates to the technical field of toy electromechanical, in particular to a toy driving mechanism.

Background technique

[0002] In the existing animal toys such as horses, the advancement is mostly based on the following scrolling and rolling forward, and the shape of the horse's rushing forward cannot be truly imitated, and the interest is not high enough.

Summary of the invention

[0003] The problem to be solved by the present invention is to provide a toy driving mechanism that drives a toy to advance.

[0004] The technical solution adopted by the utility model is: a toy twisting and advancing mechanism, comprising a toy rack, wherein the toy rack is provided with a front and rear leg synchronous relative swinging mechanism, and the front and rear legs are synchronously driven by the relative swinging mechanism. The rotating shafts are synchronously oscillated, and the swinging direction is opposite, and the front legs and the bottoms of the rear legs are provided with one-way forward rollers.

[0005] In the above solution, preferably, the front and rear leg synchronous oscillating mechanism includes a battery and a driving motor, and the driving motor drives the cranks to rotate before and after driving through a gearbox, and the front and rear cranks are respectively driven by a link. Before and after the rocker swings, the front and rear cranks, the connecting rods and the front and rear rockers respectively form the front and rear crank rocker mechanisms, and the front and rear rockers are axially fixed with the rotating shafts of the front and rear legs of the toy respectively, and the front and rear shafts are driven. Synchronous swing, and the direction of the swing is opposite. In this way, when the driving motor rotates, the front and rear legs are synchronously moved by the two crank rocker mechanisms, that is, the synchronous phase is close to or the synchronous phase is separated, and when the synchronous approach is approaching, the roller on the rear leg can be Rolling forward, and the roller on the front leg can't roll backwards. It shows that the front leg does not move and the hind leg moves forward. When the phase is separated, the roller on the front can roll forward, on the hind leg. Since the roller cannot be rolled backwards, the rear leg does not move, the front leg moves forward, and in the case of continuous motion, it moves forward.

[0006] In the above solution, it is preferable that the one-way forward roller is a roller with a one-way bearing or a ratchet. Of course, it can be another general structure that can achieve one-way advancement.

[0007] In the above solution, preferably, the toy frame is further provided with a steering mechanism, the steering mechanism includes a steering motor and a gearbox, and the steering motor drives a steering gear to rotate in a forward and reverse direction through the gearbox, the steering The gear drives a rack to swing left and right. The rack is provided with a pull rod. The pull rod pulls a direction rod to swing left and right. The left and right ends of the direction rod are respectively provided with a sliding slot, and the sliding slots are respectively placed on the left of the toy. On the sliders on the legs and the right leg, a slider chute structure is formed. When the direction bar swings left and right, the slider is pushed to move, and the slider is connected to the support rod of the roller, thereby driving the support rod to rotate, so that the left leg and the right leg are on the left leg and the right leg. The angle of rotation of the roller achieves steering.

[0008] The utility model has the beneficial effects that: the utility model drives the front and rear legs by synchronously swinging relative to the front and rear legs. The step-to-phase movement, combined with the one-way advancement of the roller, allows the front legs and the hind legs of the toy to take turns in advance, and realizes the form of jumping and rushing forward, which is more novel and interesting.

detailed description

[0010] As shown in FIG. 1 and FIG. 2, the toy driving mechanism includes a toy rack 1, and the toy rack 1 is provided with a battery (not shown in the lower part of the toy rack 1) and a driving motor 2, and the driving motor 2 passes. After the gearbox 3 is shifted, each of the front and rear cranks 4, 5 is rotated, and the front and rear cranks 4, 5 are respectively driven by a link 6, 6 to swing the front and rear rockers 8, 9 respectively, as shown in FIG. 3 and FIG. (For the sake of clarity, the steering mechanism and other components are removed.) The front and rear cranks, the connecting rods and the front and rear rockers constitute the front and rear crank lever mechanisms, and the front and rear rockers 8, 9 are respectively associated with the front and rear legs of the toy. The rotating shafts 10 and 11 are axially fixed, and the front and rear rotating shafts 10 and 11 are synchronously oscillated, and the swinging direction is opposite. The front legs and the rear legs are provided with one-way forward rollers 12 and 13, and the rollers 12 and 13 adopt a ratchet structure. The method realizes one-way advancement. When the driving motor 2 rotates, synchronous front and rear movements between the front leg and the rear leg are driven by the front and rear crank rocker mechanisms, that is, the synchronous phase is close to or the synchronous phase is separated, when the synchronous approach is approached. At this time, the roller 13 on the rear leg can be rolled forward, and the roller 12 on the front leg cannot be rolled backward. At this time, the front leg does not move, and the rear leg moves forward. When the phase separation is synchronous, the front leg is separated. The roller 12 can be rolled forward, and the roller 13 on the rear leg cannot be rolled backwards, so that the rear leg does not move, the front leg moves forward, and in the case of continuous motion, it moves forward.

[0011] The toy frame 1 is further provided with a steering mechanism, as shown in FIG. 5 (for the sake of clarity, components such as a crank rocker mechanism are removed), the steering mechanism includes a steering motor 14 and a gearbox 15, and the steering 14 motor is shifted. The box 15 drives a steering gear 16 to rotate in the forward and reverse directions, the steering gear 16 drives a rack 17 to swing left and right, the rack 17 is provided with a pull rod 18, and the pull rod 18 pulls a direction rod 19 to swing left and right, and the direction rod 19 is left and right. Each of the ends is provided with a chute 20, 21, and the chutes 20, 21 are respectively sleeved on the sliders 22, 23 on the left and right legs of the toy to form a slider chute structure, and the slider 22 is pushed when the direction bar 20 swings left and right. 23, the sliders 22, 23 are respectively connected to the support rods 24 of the left leg and the right leg of the toy, thereby driving the support rod 24 to rotate, so that the rotation angle of the rollers on the left and right legs is turned.
