Description

Technical Field

[0001] The invention relates to the technical field of bionic robots, and in particular to a bionic phage structure. Background Art

[0002] Bionic robots have been one of the research hotspots in recent years. Since creatures in nature have special abilities, humans imitate their structures and movements and apply them to robots, thus obtaining robots with better performance and more beautiful structures. For example, the bionic dragonfly has super high sensitivity and stability by swinging its head and tail.

[0003] At present, bionic robots are mainly based on the morphology and functions of animals or plants, and there are few studies on the bionics of microorganisms. In terms of teaching microorganisms, due to their small size and invisible to the naked eye, it is difficult to understand their related structures and activities by observing the real objects. Therefore, if we can make a microorganism model that is magnified a certain number of times to be actually visible and can show its main characteristics and movement methods, it will be very beneficial to the development of teaching and learning.

[0004] The main movement modes of bacteriophages include crawling with legs, opening and closing of head shell, and unwinding of DNA inside the head. Most of the bionic models of bacteriophages on the market are static, usually assembled from plastic and other materials to produce the external structure of bacteriophages, which makes it difficult to fully present the movement modes of bacteriophages. Therefore, the research prospects of dynamic bacteriophage-like robots are broad and have great application potential.

It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0033] Embodiment 1

[0034] like Figure 1 As shown, a bionic phage structure provided according to the present invention includes a trunk structure 4, a foot-leg structure 2 and a head structure 3, wherein the trunk structure 4 connects the foot-leg structure 2 and the head structure 3. The foot-leg structure 2 includes a foot chassis 215 and a bionic leg, wherein the bionic leg is movably mounted on the peripheral side of the foot chassis 215, and a first driving component for driving the bionic leg to swing is arranged in the foot chassis 215. The head structure 3 includes a head base and a head shell 301, wherein a plurality of head shells 301 are rotatably mounted on the peripheral side of the head base, and a second driving component for driving the plurality of head shells 301 to open or close is arranged in the head base. Two DNA single strands 101 are arranged in the space formed by the closure of the head shell 301, and a third driving component for driving the two DNA single strands 101 to separate or close is also arranged in the space formed by the closure of the head shell 301.

[0035] By driving the bionic legs to swing with the first driving component, driving the head shell 301 to open or close with the second driving component, and driving the two DNA single chains 101 to separate or close with the third driving component, the simulation of the three functions of bacteriophage foot movement, head opening and closing, and DNA unwinding is achieved.

[0036] like Figure 1 , Figure 2 as well as Figure 3 As shown, specifically, the foot chassis 215 is cylindrical, and four groups of bionic legs are evenly distributed around the cylindrical foot chassis 215. Since the structures, connection relationships with the foot chassis 215, and movement principles of the four groups of bionic legs are the same, one group of bionic legs is now taken as an example for explanation:

[0037] The bionic leg comprises a rotating disk 208, a first arc-shaped connecting rod 209, a short connecting rod 210, a long connecting rod 212 and a spindle-shaped rod 213. The rotating disk 208 is rotatably connected to the outer wall of the middle part of the height direction of the foot chassis 215, one end of the arc-shaped connecting rod is eccentrically hingedly connected to the rotating disk 208, the other end of the arc-shaped connecting rod is rotatably connected to the spindle-shaped rod 213, one end of the short connecting rod 210 is rotatably connected to the lower part of the height direction of the foot chassis 215, the other end of the short connecting rod 210 is rotatably connected to the middle part of the arc-shaped connecting rod, one end of the long connecting rod 212 is rotatably connected to the upper part of the height direction of the foot chassis 215, and the other end of the long connecting rod 212 is rotatably connected to the upper end of the spindle-shaped rod 213. Thus, it is used to simulate the general shape of the phage foot.

[0038] The interior of the foot chassis 215 is hollow, and the first driving assembly is installed in the interior space of the foot chassis 215. The first driving assembly includes an intermediate connecting rod 202, an intermediate gear 204, a driven connecting rod 203, and a side driven gear 207. The intermediate connecting rod 202 is rotatably installed in the middle of the foot chassis 215, and the intermediate gear 204 is rotatably arranged in the foot chassis 215, and the intermediate gear 204 is coaxially fastened to the intermediate connecting rod 202. One driven connecting rod 203 is rotatably connected to each other on both sides of the intermediate gear 204, and the driven connecting rods 203 are evenly arranged on both sides of the intermediate connecting rod 202. One side driven gear 207 is coaxially fastened to each of the two driven connecting rods 203, and the two side driven gears 207 are respectively meshed with the intermediate gear 204. Both ends of the two driven connecting rods 203 pass through the foot chassis 215 , and both ends of the two driven connecting rods 203 are coaxially fastened to a rotating disk 208 , thereby realizing the installation of four rotating disks 208 on the foot chassis 215 .

[0039] More specifically, one end of the middle link 202 passes through the foot chassis 215, and a knob 201 is fixedly installed on one end of the middle link 202 passing through the foot chassis 215. The knob 201 is manually rotated to drive the middle link 202 to rotate, thereby driving the middle gear 204 to rotate, thereby driving the two driven gears to rotate at the same time, and then driving the four rotating disks 208 at the same time. The four rotating disks 208 rotate to drive the corresponding first arc-shaped link 20, short-connection link 210, long-connection link 212 and spindle-shaped rod 213 to swing, thereby simulating the movement of the foot of the bacteriophage. It should be emphasized that any driving member in the prior art can also be used to drive the middle link 202 to rotate to provide power for the movement of the bacteriophage.

[0040] Preferably, the radii of the middle gear 204 and the two side driven gears 207 are the same, so as to ensure the consistency of the number of rotation angles. A plurality of folded thin rods 214 are arranged on the spindle-shaped rod 213 to imitate the synaptic structure on the foot of the bacteriophage.

[0041] It should be noted that the first arc-shaped connecting rod 20, the short connecting rod 210, the long connecting rod 212 and the spindle-shaped rod 213 connected to the same rotating disk 208 are all located in the same plane as the rotating disk 208, and the hinged connection between the first arc-shaped connecting rod 20 and the rotating disk 208, and the hinged connection between the first arc-shaped connecting rod 20 and the spindle-shaped rod 213 are all achieved by bolts.

[0042] like Figure 1 , Figure 4 , Figure 5 as well as Figure 6 As shown, the trunk structure 4 is in a long strip shape, the lower end of the trunk structure 4 is connected to the foot chassis 215, and the top of the trunk structure 4 is connected to the lower end of the head base. The shape of the head shell 301 simulates the shape of the bacteriophage head, and the lower end of the head shell 301 is provided with a gear part, which extends into the interior of the head base, and the head shell 301 has six gear parts evenly distributed around the circumference of the head base.

[0043] The head base includes an upper base 304 and a lower base 310, which are relatively fixed by the base fixture 303, and a space for installing the second drive device exists between the upper base 304 and the lower base 310. A notch is provided on the upper base 304 to allow the gear part at the lower end of the head shell 301 to pass through, and a shell fixture 302 is also provided on the upper base 304. The head shell 301 is rotatably connected with the shell fixture 302 through a cylindrical pin, and the central axis of the cylindrical pin connecting the head shell 301 and the shell fixture 302 is the rotation axis of the head shell 301. Specifically, there are six notches on the upper base 304, and one shell fixture 302 is installed on both sides of any notch, respectively. The gear part at the lower end of the head shell 301 penetrates from the notch into the lower part of the upper base 304, and the head shell 301 is installed on the upper base 304 through the shell fixture 302 on both sides of the corresponding notch and the cylindrical pin.

[0044] The second driving assembly is arranged in the head base, and the second driving assembly includes a driving gear 309, a passive gear 308, a sliding key 306 and a matching rack 307. The driving gear 309 and the passive gear 308 are located in the same plane and meshed with each other. A cylindrical pin is arranged on the passive gear 308, and the central axis of the cylindrical pin is parallel to the central axis of the passive gear 308, and the central axis of the cylindrical pin and the passive gear 308 are not colinear. The sliding key 306 is arranged above the passive gear 308 and slides with it. A long strip groove is provided on the sliding key 306, and the cylindrical pin extends upward into the long strip groove and slides with it. The matching rack 307 is fixed above the sliding key 306, and the matching rack 307 meshes with the gear part at the lower end of the head shell 301, so as to control the opening and closing movement of the head shell 301.

[0045] Specifically, the driving gear 309 and the passive gear 308 are both mounted on the lower base 310, and the upper surfaces of the driving gear 309, the passive gear 308 and the lower base 310 are coplanar. More specifically, six passive gears 308 are evenly arranged on the circumference of the driving gear 309, and the passive gears 308 correspond to the head shell 301 one by one. An inner gear ring is arranged on the inner circumference of the lower base 310, and the six passive gears 308 are all meshed with the inner gear ring. Thus, the installation of one driving gear 309 and six passive gears 308 on the lower base 310 is realized, and the central axis of the driving gear 309 is colinear with the central axis of the lower base 310.

[0046] Furthermore, the number of the sliding keys 306 is the same as the number of the passive gears 308 and corresponds to each other. Any sliding key 306 is arranged above the corresponding passive gear 308 and slides with it. Through the cooperation between the cylindrical pin eccentrically arranged on the passive gear 308 and the long strip groove on the sliding key 306, when the passive gear 308 rotates, the sliding key 306 can slide back and forth along the length direction of the sliding key 306.

[0047] The driving gear 309 rotates, which can simultaneously drive the six passive gears 308 to rotate, and then drive the six sliding keys 306 to slide, and then the six head shells 301 are opened and closed by meshing the matching rack 307 installed on the sliding key 306 with the gear part at the lower end of the head shell 301, specifically realizing the head movement of the simulated bacteriophage. It should be noted that the power source for the rotation of the driving gear 309 can be any driving member in the prior art that can drive the gear to rotate.

[0048] like Figure 6 , Figure 7 as well as Figure 8As shown, six head shells 301 are closed to form the head space of the bacteriophage, and a DNA chain consisting of two DNA single strands 101 is arranged in the head space of the bacteriophage. The DNA single strand 101 is a strip-shaped component with a spiral structure, which is used to simulate the shape of DNA.

[0049] A large gear 105 is fixedly disposed on the upper portion of the head base, and the third driving assembly is disposed on the large gear 105 . The third driving assembly includes a turntable 104 , a first central gear 106 , a DNA base 103 , a second arc-shaped connecting rod 102 , a transition gear 107 and a conversion gear 109 . The turntable 104 is coaxially rotatably arranged above the large gear 105, the first central gear 106 is coaxially rotatably connected to the turntable 104, two DNA bases 103 are arranged in parallel on the turntable 104, the two DNA bases 103 are respectively located on both sides of the first central gear 106, the two DNA bases 103 are respectively meshed with the first central gear 106, and a single DNA chain 101 is fixedly installed on the two DNA bases 103; the transition gear 107 is rotatably connected to the turntable 104, the rotating shaft of the conversion gear 109 is fixedly connected to the turntable 104, the lower part of the conversion gear 109 is meshed with the large gear 105, the upper part of the conversion gear 109 is connected to the transition gear 107, one end of the second arc-shaped connecting rod 102 is hingedly connected to one of its DNA bases 103, and the other end of the second arc-shaped connecting rod 102 is eccentrically hingedly connected to the transition gear 107.

[0050] The DNA base 103 includes a rack portion and a slot portion, wherein the rack portion meshes with the first central gear 106, and the slot portion is used to insert and install the DNA single strand 101, and the slot portion extends upward in a U shape from the connection between the rack portion and the slot portion. The baffle 108 guides the rack portion of the DNA base 103 to move linearly.

[0051] Specifically, the second arc-shaped connecting rod 102 connects the transition gear 107 and a DNA base 103, and is an important component for converting rotation into translation. One of the two DNA bases 103 is connected to the second arc-shaped connecting rod 102 to form a crankshaft connecting rod structure. The other is not connected and is only driven by the first central gear 106. The DNA base 103 has a U-shaped structure, one side is lower, and is a rack structure, which is engaged with the first central gear 106 and can only move linearly under the restriction of the baffles 108 on both sides. The other side is higher, and there is a slot portion formed by a platform slot structure for fixing the DNA single strand 101.

[0052] The turntable 104 is the platform of the entire unwinding structure, which is placed on the large gear 105. A driving member can be set below the turntable 104 to drive the turntable 104 to rotate. When the turntable 104 rotates, it drives the shaft of the conversion gear 109 to make a circular motion. The large gear 105 is fixedly connected to the head base, meshes with the conversion gear 109, and plays a role in supporting the turntable 104. The first central gear 106 is in the center of the turntable 104 and plays a transmission role, so that the two DNA bases 103 move symmetrically.

[0053] The transition gear 107 meshes with the conversion gear 109 to change the direction of rotation and solve the problem that the linear motion distance after conversion does not match the disc size when the conversion gear 109 is directly used as a crankshaft connecting rod. The rotating shaft of the transition gear 107 is fixed on the rotating disc 104, and an eccentric pin is provided on the upper layer of the transition gear 107 to connect the second arc connection to form a crankshaft connecting rod structure.

[0054] The turntable 104 rotates, and the large gear 105 does not move, driving the shaft of the conversion gear 109 to move, thereby driving the conversion gear 109 to rotate, thereby driving the transition gear 107 meshing with the conversion gear 109. Due to the movement of the crankshaft connecting rod structure, one DNA base 103 performs linear reciprocating motion, driving the first central gear 106 to rotate, and then driving the other symmetrically meshed DNA base 103 to perform reverse linear reciprocating motion. Therefore, the DNA base 103 performs a centrally symmetrical reverse linear motion relative to the central axis of the turntable 104, driving the two middle DNA single strands 101 to perform separation-closing motion.

A first bevel gear 205 is coaxially and firmly connected to the middle connecting rod 202, and the first bevel gear 205 is located in the middle of the foot chassis 215. A second bevel gear 206 is meshed with the first bevel gear 205, and the second bevel gear 206 is located above the first bevel gear 205. The central axis of the second bevel gear is perpendicular to the central axis of the first bevel gear. A transmission shaft 311 is firmly connected to the upper part of the second bevel gear 206, and the transmission shaft 311 passes through the trunk structure 4 upward from below, and is coaxially and firmly connected to the driving gear 309, and then passes through the head base upward and is coaxially and firmly connected to the turntable 104.
