Description

Technical Field

[0001] The utility model relates to the technical field of robots, and particularly relates to a remotely controllable trigger jumping bionic frog robot with a long-jumping purpose and a frog shape. Background Art

[0002] At present, a series of important scientific research results have been achieved in bionic mechanical frogs. In terms of the morphological design of frogs, researchers have started from the body structure, muscle system and movement mechanism of frogs, successfully realized the morphological simulation of bionic mechanical frogs, and compared and analyzed their movement behaviors with real frogs. In terms of motion control, researchers have proposed a series of advanced and efficient control algorithms, enabling bionic mechanical frogs to walk, jump and even swim in a similar way to real frogs. This device is designed and manufactured based on the basic jumping principle of frogs. Content of the Utility Model

[0003] The purpose of the utility model is to design and manufacture a lightweight bionic frog jumping robot with a frog shape, which can be remotely controlled and triggered.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model to solve this technical problem is:

[0005] A remote control automatic trigger jumping device imitating the frog jumping principle: It includes an infrared remote sensing control module, an N20 reduction motor, a reduction gear set, an energy storage and release structure, a bionic frog leg structure, and a bionic frog head structure. The infrared remote sensing module can control the forward and reverse rotation and start and stop of the reduction motor; the reduction gear set includes a driving gear and a reduction gear. Their module is 0.5, the driving gear Z = 15, which is located on the motor shaft and fixedly connected to it, and the reduction gear Z = 50. The energy storage and release structure includes a rack, an incomplete gear and a rubber band with a module of 0.5, where the gear Z = 34 and the actual number of teeth is 28. The bionic frog leg structure includes front leg pieces, rear leg pieces, a rack fixator, left and right foot webs and front legs. The bionic frog head structure includes left and right side plates, a rear bottom plate, and a leg fixator. The head is designed as a hollow frame, and components such as gears, motors, and rotating shafts are embedded between the two clamping plates.

[0006] A remote control automatic trigger jumping device imitating the frog jumping principle: Its basic working principle is that after the infrared remote control starts the motor, through the reduction gear set, the incomplete gear gently meshes with the rack. Since the rack fixator and the two side foot webs are fixedly connected by a connecting rod, the rack remains in contact with the ground, the relative position of the incomplete gear and the machine shell remains unchanged, and the incomplete gear drives the bionic frog head to move downward. Due to the connecting rod structure of the bionic frog legs, the rubber band is stretched to store energy. When the incomplete gear moves to the toothless end, the rack and the incomplete gear lose the condition of meshing. The potential energy stored in the rubber band is instantly released, and with the front leg as the fulcrum, it makes a lever movement and jumps out.

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows: The legs adopt elastic sheet-mounted connecting rods, which are light in weight, convenient for connection and installation, and have a simple manufacturing process; the head adopts a frame design, and the components are embedded for installation, reducing the weight of the head while increasing the stability of the head structure; the incomplete gear and rack are used in cooperation, and the toothless part of the incomplete gear is used as the release condition, enabling the elastic potential energy to be automatically released.

Specific Embodiments

[0013] The following further describes the present utility model with reference to the drawings.

[0014] As Figure 1 , Figure 2A remote control automatic trigger type jumping device imitating the frog jumping principle: It includes an infrared remote sensing control module, an N20 reduction motor, a reduction gear set, an energy storage and release energy structure, a structure imitating the frog's leg, and a structure imitating the frog's head. The infrared remote sensing module can control the forward and reverse rotation and start and stop of the reduction motor 15; the reduction gear set includes a driving gear 17 and a reduction gear 16. Their module is 0.5, the driving gear Z = 15, which is located on the motor shaft and fixedly connected to it, and the reduction gear 16, Z = 50. The energy storage and release energy structure includes a rack 9, an incomplete gear 15 and a rubber band a with a module of 0.5, where the gear Z = 34 and the actual number of teeth is 28. The bionic frog leg structure includes a front leg 1, a sheet-like leg rod 6, and a foot web 10. The structure imitating the frog's head includes left and right side plates 2, a rear bottom plate 12, and a leg fixator 5. The head is a hollow frame design, and components such as gears, motors, and rotating shafts are embedded between the two clamping plates. Among them, the reduction motor passes through the left side plate 2 and the right side plate 2 and is tightly connected to both. The driving gear 17 is fixedly connected to the motor shaft. The driving gear 17 meshes and drives with the reduction gear 16. The reduction gear 16 and the incomplete gear 15 are fixedly connected to the same rotating shaft 2. While the reduction gear 16 rotates, the incomplete gear 15 meshes and drives with the rack 9. One end of the upper two sheet-like leg rods 5 is coaxially fixed with a screw at the upper circular hole of the leg fixator 5, and the leg fixator 5 is also fixedly connected to the two side plates 3 of the frog's head. The upper and lower sheet-like leg rods 5 are connected with a connecting rod with a clearance fit, and the lower sheet-like leg rod 5 is also connected with the small holes of the foot web 9 with a clearance fit. The rack 8 is fixedly connected to the two foot webs 9. The rubber band a is sleeved on the two connecting shafts 8 as shown in the figure.

[0015] Its basic working principle is that after the motor is started by infrared remote control, through the reduction gear set, the incomplete gear gently meshes with the rack. Since the rack fixator and the two side foot webs 10 are fixedly connected by a connecting rod, the rack 9 keeps in contact with the ground, the relative position of the incomplete gear 15 and the machine shell remains unchanged, and the incomplete gear drives the structure imitating the frog's head to move downward. Due to the connecting rod structure of the bionic frog legs, the rubber band a is stretched to store energy. When the incomplete gear 15 moves to the toothless end, the rack and the incomplete gear 15 lose the condition of meshing. The potential energy stored in the rubber band a is instantly released, taking the front leg as the fulcrum, and making a lever movement to jump out.
