Detailed Description

For a better illustration of the objects, technical solutions and advantages of the present utility model, the following detailed description of the present utility model will be given with reference to the accompanying drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.

As shown in fig. 1 and 2, an electric bipedal walking bionic toy according to an embodiment of the present utility model. The toy comprises a head 10, a torso 20, legs 30, a palm 40, and a tail 50. The head 10, the trunk 20, the legs 30, the palm 40 and the tail 50 are respectively hollow shells simulating the appearance of dinosaur. The leg portions 30 are arranged in two, and the left and right leg portions 30 are respectively hinged to the left and right sides of the trunk portion 20. The underside of each leg 30 is hingedly connected to a palm 40. Since the leg portion 30 and the body portion 20 are connected by the hinge, the left and right leg portions 30 can be rotated with respect to the body portion 20 about the leg hinge portions 33, respectively. Similarly, the palm 40 and the leg 30 can be relatively rotated at the hinge position. In order to achieve the action of the legs 30 and palms 40 of the toy, a corresponding drive mechanism is also required.

For the purposes of this utility model, the toy also includes a first drive mechanism 60 and a second drive mechanism 90. The first driving mechanism 60 is fixedly disposed in the body 20, and is used for driving the leg portions 30 on the left and right sides to reciprocally rotate around the hinge position. The bottom sides of the palm parts 40 on the left and right sides are provided with walking wheels 41. The second driving mechanism 90 is provided with two. The two first driving mechanisms 60 are respectively disposed in the left and right palm portions 40, and are used for providing rotation power for the travelling wheels 41 by the first driving mechanisms 60.

It is worth to say that the working principle of the utility model is as follows: when the bionic toy performs a walking motion, the first driving mechanism 60 and the second driving mechanism 90 simultaneously operate. The first driving mechanism 60 can make the leg parts 30 on the left and right sides perform an alternate swinging motion relative to the body leg hinging position 33, and the palm part 40 swings along with the leg parts, so that the motion of bipedal walking is simulated. It will be appreciated that the alternating swing of the legs 30 merely simulates the action of both feet of a dinosaur, whereas the walking of a dinosaur does not rely on the alternating swing of the legs 30. The two second driving mechanisms 90 can rotate the traveling wheels 41 hidden at the bottom sides of the left and right palm portions 40, so that the palm portions 40 generate power for traveling on the traveling surface.

It will be appreciated that since the two second drive mechanisms 90 on the left and right sides are independent, the toy may produce a bipedal left-turn walking effect when the left traveling wheel 41 is stalled or rotated backwards and the right traveling wheel 41 is rotated forwards, a bipedal right-turn walking effect when the left traveling wheel 41 is forward and the right traveling wheel 41 is stalled or rotated left, and a bipedal forward or backward walking effect when the left and right traveling wheels 41 are rotated forwards or backwards at equal speeds.

Therefore, the electric biped walking bionic toy disclosed by the utility model is coordinated and matched with the whole dinosaur motion driven by the sole in the swinging of the left leg 30 and the right leg 30, and can bring the feeling that a user dinosaur walks quickly through the biped omni-directions, so that the simulation degree and the interestingness are improved.

To effect swinging of the left and right leg portions 30 relative to the torso portion 20, referring to fig. 2, in particular, the first drive mechanism 60 includes a first motor 61, a first speed gear set 62, and a swing assembly 70. The swinging assembly 70 is composed of a first eccentric shaft 71, a second eccentric shaft 72, a first sliding block 73 and a second sliding block 74, and the first eccentric shaft 71 and the second eccentric shaft 72. The first speed gear set 62 is configured with five intermeshing gears, the foremost gear being the input gear of the first speed gear set 62, meshed with the output gear of the first motor 61. The final gear is the output gear of the first speed change gear set 62, the right side of the rotating shaft of the output gear of the first speed change gear set 62 is fixedly connected to the center of the first eccentric shaft wheel 71, and the left side of the rotating shaft of the output gear of the first speed change gear set 62 is fixedly connected to the center of the second eccentric shaft wheel 72, so that the rotation of the first motor 61 drives the first eccentric shaft wheel 71 and the second eccentric shaft wheel 72 to rotate respectively after speed reduction and speed change. Two limit sliding grooves 77 extending transversely and linearly are respectively arranged on the first sliding block 73 and the second sliding block 74, and limit rods extending into the limit sliding grooves 77 of the first sliding block 73 and the second sliding block 74 are correspondingly arranged on the inner side of the body part 20. The first slider 73 is fitted with a stopper slide groove 77 in a right stopper rod provided inside the trunk portion 20, so as to be capable of sliding linearly in a lateral position near the inside of the trunk portion 20 of the right leg portion 30. The second slider 74 is engaged with a limit groove 77 provided in a left limit lever on the inner side of the body section 20, so as to be capable of being linearly slid at a lateral limit position near the inner side of the body section 20 of the left leg section 30. The first slider 73 and the second slider 74 are respectively provided with a transmission chute 76 extending longitudinally and linearly, and the output eccentric shaft of the first eccentric shaft wheel 71 is arranged in the transmission chute 76 of the first slider 73, so that the first slider 73 moves linearly and reciprocally along the limit chute 77 along with the rotation of the first eccentric shaft wheel 71. The output eccentric shaft of the second eccentric shaft wheel 72 is arranged in the transmission chute 76 of the second slider 74, so that the second slider 74 moves linearly and reciprocally along the limit chute 77 along with the rotation of the second eccentric shaft wheel 72. The outer sides of the first slider 73 and the second slider 74 are provided with push rods 75, respectively. The push rod 75 moves with the lateral reciprocation of the first slider 73 and the second slider 74. The push rod 75 of the first slider 73 extends into the right leg 30 offset from the leg joint 33, thereby reciprocating the leg joint 33 of the right leg 30. The push rod 75 of the second slider 74 extends into the left leg 30 offset from the leg joint 33, thereby reciprocating the leg joint 33 of the left leg 30.

Further, as shown in fig. 2, the output eccentric shafts of the first eccentric shaft 71 and the second eccentric shaft 72 are 180 ° out of phase on the axis. Thus, as shown in fig. 2, when the first slider 73 slides rearward, the second slider 74 correspondingly slides forward. Then, when the right leg 30 swings to the rearmost side, the left leg 30 swings to the frontmost side accordingly. In other words, the swing assembly 70 can enable the left and right leg portions 30 to swing to have the characteristic of reverse phase, so as to achieve the simulation of the bipedal walking posture.

Further, as shown in fig. 2, the tail 50 is hinged to the rear side of the body 20, and the hinge shaft is longitudinally arranged so that the tail 50 can swing left and right with respect to the body 20. Meanwhile, the first slider 73 and the second slider 74 are provided with rearward extending ends, respectively, and the rear sides of the extending ends are provided with coil springs 79. As the first slider 73 slides rearward, not only will the +right leg 30 swing forward, but the coil spring 79 of the first slider 73 will abut the right side of the tail 50 pushing the tail 50 to swing leftward. Similarly, as the second slider 74 slides rearward, the left leg 30 swings forward, pushing the tail 50 to swing rightward. It will be appreciated that during normal operation, the coil spring 79 can urge the tail 50 to swing, and when the tail is manually moved, the spring is compressed and the tail is not in rigid contact with the slider, avoiding stalling of the sliding teeth and motor. It can be seen that by the cooperation between the first slider 73, the second slider 74 and the tail portion 50, both foot swinging and simultaneous swinging of the tail portion 50 can be achieved.

Further, as shown in fig. 1, the tail 50 is composed of three tail parts 51, and each tail part 51 is sequentially reduced from front to back to form an integral dinosaur tail 50. The adjacent tail segments 51 are hinged to each other in a vertical direction so as to be relatively swingable between left and right sides. The tail split 51 at the front end is hinged to the body 20, and the first slider 73 and the second slider 74 sequentially abut against and push the tail split 51 at the front end, so that the two tail split 51 at the rear side swing accordingly, thereby simulating the lifelike large-amplitude swing of the whole tail 50.

To avoid slip teeth and motor stalling due to the leg portions 30 getting stuck, as shown in fig. 2, in particular, this embodiment is such that each leg portion 30 is hinged to the trunk portion 20 at a leg hinge position 33, and each leg portion 30 is provided with a leg torsion spring 32. Taking the right leg 30 as an example and the left side as a similar way, the leg torsion spring 32 is sleeved and fixed at the body leg hinge position 33 of the right leg 30, the two elastic ends of the leg torsion spring 32 extend radially and are respectively overlapped at a column of the leg 30, and the push rod 75 of the first slider 73 penetrates between the two elastic ends of the leg torsion spring 32 in a manner deviating from the body leg hinge position 33. When the first slider 73 slides laterally, the push rod 75 of the first slider 73 pushes one elastic end of the leg torsion spring 32 to move, and the other elastic end of the leg torsion spring 32 drives the leg 30 on the right side to swing. At this time, if the leg 30 is artificially swung, the leg 30 pushes the elastic end of the leg torsion spring 32 to move, and the push rod 75 of the first slider 73 can continue to slide laterally against the push rod 75 of the first slider 73.

To achieve a straight posture of the palm portion 40 when swinging with the leg portion 30, as shown in fig. 2, specifically, in this embodiment, taking the right leg portion 30 as an example and the left side as a matter of course, the right leg portion 30 is provided with the leg link 31, and the right palm portion 40 is provided with the first palm hinge position 43 and the second palm hinge position 44. The first palm hinge site 43 and the second palm hinge site 44 are disposed relatively back and forth in the traveling direction. The upper end of the right leg 30 is hingedly connected to the torso portion 20, while the lower end of the right leg 30 is hingedly connected to the second palm hinge location 44 of the palm portion 40. In other words, palm 40 is rotatable relative to leg 30 at second palm hinge location 44. One end of the link is hingedly connected to the torso 20 through the leg 30 and the other end of the leg link 31 is hingedly connected to the first palm hinge location 43. In other words, the leg link 31 is rotatable at both ends thereof with respect to the trunk portion 20 and the palm portion 40, respectively. It will be appreciated that the leg 30, palm 40 and leg link 31 form a multi-link structure that enables the palm 40 to remain level so that the road wheels 41 on the underside of the palm 40 remain in contact with the ground.

Further, as shown in fig. 2, the right leg 30 is taken as an example, and the left palm 40 is provided with two traveling wheels 41. The two road wheels 41 are axially parallel to each other, one road wheel 41 being arranged on the front side in the traveling direction, and the other road wheel 41 being arranged on the rear side in the traveling direction. At least four auxiliary wheels 42 are further provided on the bottom side of the palm portion 40, one of which is provided in front of the front traveling wheel 41, one of which is provided behind the rear traveling wheel 41, and the other two are provided on both sides in the traveling direction one by one. The second drive mechanism 90 is composed of a second motor 91 and a third speed change gear set. The second motor 91 is drivingly connected to the front side of the third speed change gear set, and the rear side of the third speed change gear set is drivingly connected to the front road wheel 41 and the rear road wheel 41, respectively. Thus, as the left and right leg portions 30 swing, at least one of the walking wheels 41 of the palm portion 40 contacts the walking surface and moves the toy, and the auxiliary wheel 42 further provides rolling contact support for the movement of the toy.

The foregoing embodiments have described primarily the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
