Description

Technical Field

[0001] The utility model relates to the technical field of bionic machinery, in particular to a novel jumping bionic frog. Background Art

[0002] Bionics is a science that studies the structure and properties of biological systems to provide new design ideas and working principles for engineering technology. It is a marginal subject between biological science and technical science. It involves disciplines such as biology, biophysics, biochemistry, physics, cybernetics, and engineering. Bionics uses the functional principles and mechanisms of various biological systems as biological models to study, and finally realize new technical designs and manufacture better new instruments and machinery.

[0003] Frogs are amphibians with excellent jumping abilities and amphibious adaptability, and they have extremely high research value in the field of bionics. Scientists have made breakthroughs in areas such as efficient jumping and new materials with high adhesion properties by exploring aspects such as their jumping power and skin adhesion, and have created more efficient equipment with broad application prospects. It is conceivable that the biomechanical and physiological characteristics of frogs provide a series of basic guarantees for the progress of natural sciences, making bionic frogs a very potential research object and providing unlimited imagination for the development of bionics.

[0004] Generally speaking, at present, bionic robots mostly use belts and tracks for transmission connections, such as bionic search and rescue robots, which also use chains to achieve transmission connections, and some use transmission shafts to achieve connections. However, existing bionic frog robots mostly use rigid mechanical structure transmission, which has a large number of mechanical parts, frequent transmission failures, poor jumping ability and efficiency, and inflexible transmission. The bionic frog robot is subject to certain functional limitations in transmission and still cannot meet the ideal requirements, leaving a large room for optimization. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a new jumping bionic frog, including a bionic board, wherein the head, trunk and forelimbs are integrated into the bionic board, and two groups of bionic boards are symmetrically arranged, and hind limbs are installed on opposite sides of the bionic board. The hind limbs are used to control the bouncing of the bionic board through a control device.

[0006] A fixing block is rotatably mounted on one end of the hind limb away from the bionic board, and a flipper is mounted on the fixing block.

This makes it more advantageous in places with limited space, such as the interior of mechanical equipment.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-Figure 5 Although the embodiments of the present invention have been described in detail, the present invention can be implemented in many different ways as defined and covered by the claims.

[0025] The embodiment of the present application discloses a novel jumping bionic frog, which illustrates that the novel jumping bionic frog is mainly used in the process of bionic mechanical design, and can avoid cleverly combining biomechanics with mechanical mechanisms in terms of technical effects, so that the bionic frog has excellent jumping function; further, the novel jumping bionic frog can also solve the problems of poor efficiency and large space occupied by traditional transmission methods.

[0026] Embodiment 1:

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, the bionic board 1 includes a bionic board 1, which is characterized in that: the bionic board 1 is an integrated arrangement of the head, trunk and forelimbs, and the bionic board 1 is symmetrically arranged with two groups, and the hind limbs 2 are installed on the opposite sides of the bionic board 1, and the hind limbs 2 are controlled by the control device 3 to control the bouncing of the bionic board 1; through the extension and retraction of the hind limbs 2, the extension and retraction of the hind limbs 2 of the frog are simulated, and then the control device 3 is used to drive the hind limbs 2 to be gradually contracted and instantly extended, so that the hind limbs 2 of the bionic frog can be extended and retracted like the hind legs of the frog, so as to achieve the purpose of driving the bionic board 1 to bounce.

[0028] A fixing block 4 is rotatably mounted on one end of the hind limb 2 away from the bionic board 1 , and a webbed foot 5 is mounted on the fixing block 4 , imitating the webbed foot 5 of a frog to achieve the effect of supporting standing.

[0029] The hind limbs 2 are tilted toward the head of the bionic board 1 with the fixed block 4 as the origin. The effect of this setting is that when the hind limbs 2 contract and extend, the stretching force can transfer energy to the ground, and the tilted setting can prompt the flippers 5 to jump forward after taking off, thereby achieving the effect of further simulating the frog's jumping movement.

[0030] The hind limb 2 includes a first connecting rod 20, a torsion spring 21 and a second connecting rod 22. The first connecting rod 20 is hinged on the opposite side of the two bionic plates 1. The second connecting rod 22 is rotatably arranged on the fixed block 4. Both ends of the torsion spring 21 are fixedly connected to the first connecting rod 20 and the second connecting rod 22. The contraction of the torsion spring 21 simulates the muscle contraction of the frog when it takes off, so that the joint between the thigh and the tibia is quickly bent to release the accumulated energy. Then, the extension of the torsion spring 21 simulates the muscle relaxation of the frog when it takes off, transfers the energy to the ground, and prompts the frog to jump forward.

[0031] The first connecting rod 20 and the second connecting rod 22 are both inclined toward the opposite side of the two bionic plates 1, and the first connecting rod 20, the torsion spring 21 and the second connection are each provided with two groups to simulate the posture of the frog's hind legs. The two groups of relatively inclined first connecting rods 20 and second connecting rods 22 can also increase the stability of the device.

[0032] Reference Figure 3 , Figure 4 and Figure 5 As shown, that is, a schematic diagram of the structure for controlling the extension and retraction of the torsion spring 21; specifically, the control device 3 includes a motor 30, a rope drum 31 is installed at the output end of the motor 30, a control rope 32 is wound around the rope drum 31, a control hook 33 is installed at the end of the control rope 32 away from the rope drum 31, a trigger structure 34 for driving the control hook 33 to work is provided on the fixed block 4, and the control hook 33 is movably connected to the trigger structure 34.

[0033] One end of the control hook 33 is fixed by a trigger mechanism. When the control rope 32 is wound around the rope drum 31, the bionic board 1 can be pulled to move along the length direction of the control rope 32, and the first connecting rod 20 and the second connecting rod 22 are both rotated under the pulling of the control rope 32, driving the torsion spring 21 to contract, thereby achieving the effect of imitating the muscle contraction of a frog when jumping. When the torsion spring 21 contracts to a certain extent, the trigger mechanism cancels the fixation of the control hook 33, the torsion spring 21 loses its tension and stretches instantly, simulating the effect of the frog's muscle relaxation when jumping, transferring energy to the ground, and prompting the frog to jump forward.

[0034] During the specific implementation process, the trigger mechanism fixes one end of the control hook 33 and starts the motor 30. Then the rope drum 31 rotates, and the control rope 32 is continuously wound on the rope drum 31. During this process, the torsion spring 21 contracts. After a certain degree, the trigger mechanism cancels the fixation of the control hook 33, and the torsion spring 21 loses the external force and stretches. The first connecting rod 20 and the second connecting rod 22 rotate under the action of the torsion spring 21, driving the flippers 5 to move and jump.

[0035] Reference Figure 3 and Figure 4 As shown, that is, a schematic diagram of the trigger structure 34; specifically, the trigger structure 34 includes a first fixed shaft 340 and a second fixed shaft 341, the first fixed shaft 340 and the second fixed shaft 341 are both arranged on the fixed block 4, and both extend to opposite sides, wherein a slider 342 is slidably provided at one end of the first fixed shaft 340, a spring 343 is installed at one end of the slider 342 located inside the first fixed shaft 340, and the end of the spring 343 away from the slider 342 is fixedly connected to the inside of the first fixed shaft 340; a control block 344 is installed at one end of the slider 342 close to the second fixed shaft 341, and a control shaft 345 is provided at one end of the control block 344 close to the second fixed shaft 341, the control hook 33 is movably connected to the control shaft 345, and a control groove for the control shaft 345 to slide is provided on the second fixed shaft 341.

[0036] In the initial state, the control shaft 345 is located in the control groove under the force of the spring 343, and the control hook 33 is limited by the control shaft 345. When the torsion spring 21 shrinks to a certain extent, under the action of external force, the slider 342 slides toward the inside of the first fixed shaft 340, the spring 343 shrinks, and the control shaft 345 moves out of the control groove. At this time, a gap is generated between the control shaft 345 and the second fixed shaft 341, and the control hook 33 slides out of the gap between the control shaft 345 and the control hook 33. The control shaft 345 cancels the limitation on the control hook 33. After the control hook 33 slides out, the control shaft 345 slides into the control groove again under the action of the spring 343.

[0037] During the specific implementation process, when the torsion spring 21 shrinks to a certain extent, the slider 342 slides toward the inside of the first fixed shaft 340, the control shaft 345 moves to the outside of the control groove, the control hook 33 slides out, and the control shaft 345 cancels the limit on the control hook 33. Then, the control shaft 345 slides into the control groove again under the action of the spring 343 and returns to the initial state.

[0038] Reference Figure 4 and Figure 5 As shown, it is a schematic diagram of the structure for driving the slider 342 to slide; specifically, a plurality of fixing plates 6 fixedly connected to the two bionic plates 1 are installed between the bionic plates 1, and a ejector pin 7 is installed on one of the fixing plates 6 at the lower end of the bionic plate 1. The ejector pin 7 is arranged along the length direction of the first connecting rod 20 and the second connecting rod 22. A control inclined surface inclined from the first fixed axis 340 to the second fixed axis 341 is provided on the control block 344, and the control inclined surface is movably abutted.

[0039] The control block 344 is squeezed by the ejector pin 7 to drive the slider 342 fixedly connected to the control block 344 to move, thereby driving the control shaft 345 to move and slide out of the control groove, thereby canceling the limit on the control hook 33.

[0040] During the specific implementation process, the bionic board 1 moves toward the fixed plate 6 under the pulling force of the control rope 32. During this process, the ejector pin 7 approaches the control block 344 until it abuts against the control block 344. The control block 344 slides under the squeezing of the ejector pin 7, driving the slider 342 to slide into the first fixed shaft 340.

[0041] During operation: the first step is to retract the hind limbs: manually hook the control hook 33 onto the control shaft 345, then the motor 30 is started, the rope drum 31 rotates, the control rope 32 is continuously wound around the rope drum 31, and under the pulling of the control rope 32, the torsion spring 21 is retracted, and the bionic board 1 moves toward the flipper 5;

[0042] Step 2: hind limb extension: the bionic board 1 moves until the ejector pin 7 contacts the control block 344. The control block 344 slides under the pressure of the ejector pin 7, driving the slider 342 to slide into the first fixed axis 340. The control axis 345 slides out of the control groove. The control hook 33 slides out from the gap between the control axis 345 and the control hook 33. The torsion spring 21 loses its tension and stretches instantaneously. The bionic board 1 quickly moves away from the flipper 5. The elastic force of the torsion spring 21 transfers energy from the flipper 5 to the ground, achieving the effect of simulating a frog jumping forward.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
