Description

Technical Field

[0001] This utility model relates to the field of simulated animal technology, and in particular to a bipedal walking mechanism for simulated animals. Background Technology

[0002] Simulated dinosaurs are models created using modern technology and based on dinosaur fossil research. They are made using a variety of materials, including mechanical, electronic, and silicone materials, and highly replicate the appearance, movements, and sounds of dinosaurs. Simulated dinosaurs can bring the abstract knowledge of dinosaurs from books to life, helping children to intuitively understand the living habits of dinosaurs, stimulating their interest in paleontology and scientific exploration. Furthermore, simulated dinosaurs can provide creators with realistic props and design inspiration, helping to create stunning visual effects and enrich the content of their works.

[0003] Currently, most animatronic dinosaurs on the market consist of a skeletal frame and silicone filler. The skeletal frame provides support, while the silicone filler realistically simulates the skin texture and color of a dinosaur, enhancing its realism. However, this design makes it difficult for the animatronic dinosaur to move. To address this issue, existing technologies often add wheels to the bottom of the animatronic dinosaur to increase its interactivity with the user. However, in actual use, because the movement of the animatronic dinosaur is achieved solely through the wheels, the realism is poor, reducing user interactivity and improving the device's practicality, failing to meet user needs.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a bipedal walking mechanism for a simulated animal, comprising a housing 1. A transmission rod 3 is rotatably connected to the inner side of the housing 1. Both ends of the transmission rod 3 pass through the housing 1 and are fixedly connected to support plates 4. The transmission rod 3 can drive the support plates 4 to rotate. Rotating shafts 5 are rotatably connected to the opposite sides of the support plates 4, causing the support plates 4 to move the rotating shafts 5. Support legs 6 are fixedly connected to the opposite sides of the two rotating shafts 5, causing the rotating shafts 5 to move the support legs 6. Connecting blocks 7 are fixedly connected to the bottom ends of the two support legs 6, and feet 8 are provided at the bottom of the two connecting blocks 7. The support legs 6 can drive the feet 8 to move through the connecting blocks 7. A drive assembly is provided inside the housing 1. Limiting components are provided on the bottom of the left and right sides of the housing 1. A disassembly mechanism 2 is provided on the top of the feet 8, which is used to facilitate the disassembly of the feet by the staff. 8. Disassembly and replacement work is carried out. The drive component includes a motor 9, which is fixedly connected to the rear side of the inside of the housing 1. The output end of the motor 9 is fixedly connected to a worm gear 10. The motor 9 will drive the worm gear 10 to rotate. The outer middle of the transmission rod 3 is fixedly connected to a worm wheel 11, which meshes with the worm gear 10. Since the worm wheel 11 meshes with the worm gear 10, when the worm gear 10 rotates, the worm wheel 11 will drive the transmission rod 3 to rotate. The limiting component includes a first slide groove 12. Two first slide grooves 12 are respectively opened on the bottom of the left and right sides of the housing 1. A slider 13 is slidably connected inside the two first slide grooves 12. A second slide groove 14 is opened on the upper middle part of the adjacent side of the two support legs 6. The far ends of the two sliders 13 are slidably connected to the corresponding second slide grooves 14. The sliders 13 can only slide inside the first slide grooves 12 and the second slide grooves 14.

[0033] Specifically, when the simulated dinosaur needs to walk, motor 9 is started, driving worm gear 10 to rotate. Since worm gear 10 meshes with worm wheel 11, worm wheel 11 rotates along with worm gear 10, and through transmission rod 3, drives the support plates 4 on both sides to rotate synchronously. At this time, one support plate 4 will drive the leg 6 on the same side to move, lifting the leg 6 and propelling it forward. Simultaneously, the other leg 6, maintaining contact with the ground, will apply force to push the box 1 forward. After the support plate 4 completes a 180-degree rotation, the feet 8 on both sides will... Simultaneous contact with the ground completes a full walking motion. By continuously repeating the above actions, the dinosaur model can achieve a continuous walking effect. In addition, the slider 13 can only slide within the first slide groove 12 and the second slide groove 14, ensuring that the support leg 6 can always maintain a vertical downward posture during movement, thereby ensuring the stability and continuity of the walking action. The simulated dinosaur using this walking mechanism has a reasonable center of gravity and can achieve upright walking of the simulated dinosaur without any external force assistance, which improves the simulation of the device and can meet the needs of users.

[0034] Reference Figure 4 , Figure 5 and Figure 6 The disassembly mechanism 2 includes a plug-in block 201, which is fixedly connected to the top of the foot 8. The plug-in block 201 has slots 202 on both its left and right sides. The connecting block 7 has movable plates 203 on both its left and right sides. A locking block 204 is fixedly connected to the middle of an adjacent side of each of the two movable plates 203. The two locking blocks 204 engage with their corresponding slots 202, thus securing the foot 8. A rack 205 is fixedly connected to the front of an adjacent end of each of the two movable plates 203. When the rack 205 moves, it drives the movable plates 203 to move. A rotating rod 206 is rotatably connected to the front of the connecting block 7. A gear 207 is fixedly connected to the rear end of the rotating rod 206. The gear 207 is fixed by the rotating rod 206 and can rotate. The upper and lower sides are respectively engaged with the corresponding racks 205. When one rack 205 moves, the other rack 205 will move accordingly through the transmission of the gear 207. A lever 208 is fixedly connected to the front wall of the left rack 205. A groove 209 is provided in the lower middle part of the front side of the connecting block 7. The front end of the lever 208 passes through the groove 209. Pulling the lever 208 can drive the left rack 205 to move. Reset components are provided at the left and right ends of the interior of the connecting block 7. The reset components include fixing rods 210. Multiple fixing rods 210 are fixedly connected to the front and rear sides of the left and right ends of the interior of the connecting block 7. Springs 211 are provided on the outer side of multiple plug-in blocks 201. One end of multiple fixing rods 210 passes through the corresponding movable plate 203. The springs 211 can push the locking block 204 to engage with the locking groove 202.

[0035] Specifically, during the use of this device, when the foot 8 is worn out and needs to be replaced, the lever 208 is pulled. The lever 208 will drive the left rack 205 to move. When the left rack 205 is driven by the lever 208, it can further drive the right rack 205 to move through the transmission of the gear 207. At this time, the racks 205 on both sides will drive the movable plates 203 on both sides to move in opposite directions. During the movement of the movable plates 203, the locking block 204 will move, so that the locking block 204 can be disengaged from the slot 202, making it easy to remove the foot 8 for replacement. When the foot 8 needs to be reinstalled, the plug block 201 is inserted into the connecting block 7. At this time, the spring 211 will push the locking block 204 to engage with the slot 202, which can fix the foot 8, improving the convenience of using the device.

[0036] Reference Figure 5 and Figure 6 One end of each of the multiple fixed rods 210 is fixedly connected to a limiting block 15, which can limit the movement of the locking block 204. The size of the locking block 204 matches the inner size of the locking groove 202.

[0037] Specifically, the limiting block 15 can limit the movement range of the locking block 204, preventing it from moving excessively and falling out of the locking range. The size of the locking block 204 matches the inner size of the slot 202, and the locking block 204 can be locked tightly with the slot 202, so that the foot 8 will not wobble.

[0038] Reference Figure 1 , Figure 3 and Figure 4 A rubber ball 16 is fixedly connected to the front end of the lever 208. The rubber ball 16 makes it convenient for the staff to move the lever 208. An anti-slip pad 17 is fixedly connected to the bottom of the foot 8. A controller 18 is fixedly connected to the front side of the box 1. The controller 18 is electrically connected to the motor 9. The operation of the motor 9 can be controlled through the controller 18.

[0039] Specifically, the rubber ball 16 can be used to easily pull the lever 208, the anti-slip pad 17 can be used to prevent the foot 8 from slipping, and the controller 18 can be used to control the operation of the motor 9, which is a F130 miniature motor.

[0040] Working principle: When the simulated dinosaur needs to walk, start motor 9. Motor 9 will drive worm gear 10 to rotate. Since worm wheel 11 meshes with worm gear 10, worm wheel 11 will rotate accordingly. Through transmission rod 3, it can drive the support plates 4 on both sides to rotate synchronously. At this time, the support plate 4 on one side will drive the leg 6 on the same side to move, thereby lifting the leg 6 and moving it forward. The other leg 6, because it is in contact with the ground, will push the box 1 forward. When the support plate 4 rotates 180 degrees, the feet 8 on both sides touch the ground at the same time, thus completing one step. Repeating the above actions can realize the walking of the dinosaur model. The slider 13 can only slide inside the first slide groove 12 and the second slide groove 14, so that the leg 6 can always be vertically downward. The simulated dinosaur using this walking mechanism has a reasonable center of gravity and can achieve upright walking of the simulated dinosaur without any external force assistance.

[0041] Furthermore, during the use of this device, when the foot 8 is worn out and needs to be replaced, pull the lever 208. The lever 208 drives the left rack 205 to move. The left rack 205, through the transmission of the gear 207, can drive the right rack 205 to move. At this time, the racks 205 on both sides will drive the movable plate 203 to move to both sides. When the movable plate 203 moves, it will drive the locking block 204 to move, thereby disengaging it from the slot 202. This allows the foot 8 to be easily removed for replacement. When the foot 8 needs to be installed, insert the plug block 201 into the connecting block 7. At this time, the spring 211 will push the locking block 204 to engage with the slot 202, thus fixing the foot 8.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
