Description

Technical Field

[0001] This utility model relates to the field of fishing gear and tools, and in particular to a biomimetic intelligent fish bait. Background Technology

[0002] With the booming development of the outdoor leisure industry, the number of people participating in fishing in my country has exceeded 200 million, and it is showing a trend of professionalization and equipment-based development. As the core fishing tackle system, bait technology has long existed in two technical routes: live bait fishing based on bioactive materials and artificial bait fishing based on artificial biomimetic materials.

[0003] Although live bait fishing has natural biological signal characteristics, it has significant technical bottlenecks: live bait needs to be equipped with oxygen supply equipment to maintain its activity, cross-regional fishing has transportation loss problems, microbial pollution leads to the risk of eutrophication of water bodies, and according to research in "Advances in Fisheries Science", the use of traditional live bait has caused water quality to exceed standards in more than 30% of fishing grounds.

[0004] However, while existing artificial lure fishing techniques avoid ecological pollution problems, they still have some shortcomings, such as: mechanically driven lures (metal spinners) have a single movement pattern and a lateral swing of less than 15°, which cannot simulate the escape behavior of real fish; fluid dynamics design flaws result in an effective underwater action time of less than 2 minutes; and the lack of a biological signal simulation system means that they can only generate a single frequency vibration of 3-5Hz. As a result, existing artificial lures have simple movements and insufficient realism, and their attack rate on target fish species is reduced by 60% compared to live bait. Consequently, the lures are not very effective at attracting fish, resulting in a low success rate and affecting the user's fishing enjoyment. Therefore, it is necessary to improve existing artificial lures to address the above shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a biomimetic intelligent fish bait that improves the fish-attracting effect, increases the success rate of fishing, and enhances the enjoyment of fishing.

The end of the snap-fit ​​portion is provided with upper and lower symmetrical ribs, and a rotating hole is provided on the ribs.

[0011] In one embodiment, the bionic tail includes an installation section and a swing tail section. The swing tail section is fastened to one end of the installation section, and a spherical buckle is provided on the inner wall of the other end of the installation section.

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Please see Figures 1 to 5A biomimetic intelligent fish bait includes a biomimetic body 100, a biomimetic tail 200, and a drive inner liner 300. The drive inner liner 300 is installed inside the biomimetic body 100. The biomimetic tail 200 is located at the tail end of the biomimetic body 100 and is connected to the drive inner liner 300 in a transmission manner. The drive inner liner 300 includes a housing 310, a drive motor 320, a cam drive shaft 330, and a rocker arm 340. The drive motor 320 is located inside the housing 310, and the output end of the drive motor 320 extends out of the housing 310 and is connected to the cam drive shaft 330. One end of the rocker arm 340 is inserted into the biomimetic tail 200, and the other end is connected to the cam drive shaft 330 in a transmission manner. The drive motor 320 drives the cam drive shaft 330 to rotate, so that the rocker arm 340 drives the biomimetic tail 200 to swing.

[0035] Specifically, in this embodiment, the bionic body 100 and the bionic tail 200 respectively simulate the body and tail of a real fish, enabling the intelligent fish bait to achieve a bionic state and a streamlined external contour. A drive inner liner 300 is installed inside the bionic body 100, and the bionic tail 200 is connected to the drive inner liner 300 for transmission. The drive inner liner 300 drives the bionic tail 200 to swing, thereby enabling the bionic intelligent fish bait to simulate the swimming and tail-wagging dynamics of real fish, thus improving the fish-attracting effect. Simultaneously, a cam drive is activated by a drive motor 320. The shaft 330 rotates, and when the cam drive shaft 330 rotates, it acts on the rocker arm 340, so that the rocker arm 340 can drive the bionic tail 200 to swing. During the swing, the single-sided swing amplitude of the bionic tail 200 can be ≥65°, and the swing frequency can reach 5-15 times / second. This makes the swing amplitude of the bionic tail 200 match the natural tail swing amplitude of the target fish species by >90%, thereby improving the realism of the bionic intelligent fish bait, thus increasing the success rate of fishing, and providing anglers with a smoother user experience, thereby enhancing the user's fishing enjoyment.

[0036] Furthermore, since the biomimetic intelligent fish bait in this embodiment operates in water, the electric inner liner 300 needs to be waterproofed. Therefore, the housing 310 of the driving inner liner 300 includes an outer shell 311 and a front cover 312. The front cover 312 is sealed to the front end of the outer shell 311, and the output end of the drive motor 320 extends from the rear end of the outer shell 311. A sealing gasket 350 is provided at the exit point. The sealing gasket 350 can be fixed to the inner wall of the rear end of the outer shell 311 by screws. The front cover 312 and the sealing gasket 350 seal the front and rear ends of the outer shell 311 respectively, thereby achieving a complete seal of the housing 310. This enables the driving inner liner 300 to achieve IP68 waterproof performance, ensuring that the biomimetic intelligent fish bait can operate in water and guaranteeing its service life.

[0037] In order to achieve the intelligent effect of the fish bait and enable the drive motor 320 to drive the bionic tail 200 to swing, the drive liner 300 in this embodiment also includes a battery 360, a PCB board 370 and an FPC board 380 disposed in the housing 310. The battery 360 is located in the middle of the housing 310, the PCB board 370 is located at the front end of the housing 310 and is fixedly connected to the front cover 312, the drive motor 320 is located at the rear end of the housing 310, and the FPC board 380 is electrically connected to the PCB board 370 and the drive motor 320 respectively. Furthermore, a water ingress sensing contact 312a and a charging contact 312b electrically connected to the PCB board 370 are also embedded on the outer surface of the front cover 312.

[0038] The battery 360 can be fixed in the middle of the outer shell 311 by the bracket, while the PCB board 370 and the drive motor 320 are located at the two ends of the battery 360 respectively. The PCB board 370 can be fixed to the front cover 312 by screws, and the drive motor 320 can be fixed by the bracket, thereby making the structural layout of the drive inner liner 300 reasonable. Then, the FPC board 380 is arranged along the inner wall of the outer shell 311, so that the two ends of the FPC board 380 are electrically connected to the PCB board 370 and the drive motor 320 respectively, thereby making the overall circuit layout of the drive inner liner 300 compact and forming a lightweight integrated circuit system. The FPC board 380 is connected to the PCB board 370 by using zebra strip connectors (0.5mm pitch), which can form a three-dimensional circuit architecture, thereby reducing the wire length by more than 40% and reducing the circuit impedance by 15%.

[0039] When the bionic smart fish bait is in use, the water-sensing contact 312a on the surface of the front cover 312 senses the liquid, thereby triggering the PCB board 370 to start the drive motor 320. The drive motor 320 then drives the cam drive shaft 330 to rotate 360°. During the rotation, the cam drive shaft 330 acts on the swing arm 340 to drive the swing arm 340 to swing back and forth, thereby driving the bionic tail 200 to achieve a bionic tail-wagging action. The bionic smart fish bait automatically cuts off the power within 0.5 seconds after leaving the water surface, thus realizing a water-sensitive trigger start-stop system. Compared with traditional mechanical switches, its response speed can be increased by 3 times, and the standby power consumption is reduced to the microamp (μA) level, realizing intelligent energy-saving control of "starting when entering the water and stopping when leaving the water", thereby improving the intelligent effect of the bionic fish bait.

[0040] Furthermore, the battery 360 uses a lithium polymer battery with a capacity of ≥1000mAh, and dynamically adjusts the power of the drive motor 320 through the MCU (3 adjustable levels: 0.5W / 1W / 1.5W), so that the bionic smart fish bait can achieve a continuous working time of ≥5 hours, which is 50% longer than similar products.

[0041] Please see Figure 5 and Figure 9 To charge the battery 360 in the drive liner 300, a positioning magnet 312c is provided on the inner wall of the front cover 312, and an interface 110 corresponding to the water ingress sensing contact 312a and the charging contact 312b is provided on the bottom of the bionic body 100. The magnetic contacts of a dedicated charger can be easily inserted through the interface 110, and the positioning magnet 312c automatically aligns and attracts the magnetic contacts, allowing them to engage with the charging contact 312b to charge the battery 360. The positioning magnet 312c is a neodymium iron boron magnet with a magnetic force ≥10N, ensuring a contact error of ≤0.5mm between the magnetic contacts and the charging contact 312b. It supports 5V / 1A fast charging, improving charging efficiency by 40% compared to traditional plug-in interfaces. Furthermore, the positioning magnet 312c allows for one-handed operation even with wet hands, significantly improving ease of use.

[0042] In addition, the biomimetic intelligent fish bait in this embodiment has a multi-band intelligent tail wagging mode. Three pre-programmed biomimetic wagging algorithms are stored in the EEPROM of the PCB board 370, including the cruising mode: fast wagging (12 times / second, lasting 5 seconds) → slow wagging (6 times / second, lasting 3 seconds) → still (1 second), simulating the normal swimming of fish; the feeding mode: high-frequency tail wagging (15 times / second, lasting 10 seconds) → disordered shaking (random wagging amplitude 40°-70°, lasting 5 seconds) → still (2 seconds), imitating injured small fish; and the danger avoidance mode: sudden strong wagging (70° amplitude, lasting 2 seconds) → intermittent pause (3 seconds), simulating the frightened state of fish. By automatically switching the wagging of the biomimetic tail 200 of the biomimetic intelligent fish bait, it can accurately simulate the dynamics of real fish cruising, foraging, and danger avoidance, thereby increasing the success rate of trapping predatory fish such as bass and mandarin fish by more than 40%.

[0043] Please see Figure 6 and Figure 7 In order to realize the reciprocating swing of the bionic tail 200, in this embodiment, a snap-fit ​​portion 311a is extended at the tail end of the outer shell 311, and a rib 311c with upper and lower symmetry is provided at the end of the snap-fit ​​portion 311a. A rotating hole 311d is provided on the rib 311c. Meanwhile, the end of the rocker arm 340 that is connected to the cam drive shaft 330 is a ball head 341, and a rotating shaft 342 that cooperates with the rib 311c is provided on the side wall of the ball head 341. A straight limiting groove 343 is provided on the end face of the ball head 341, and part of the cam drive shaft 330 is placed in the straight limiting groove 343.

[0044] By inserting the rotating shafts 342 on the upper and lower sides of the ball head 341 into the rotating holes 311d of the ribs 311c on the upper and lower sides of the snap-fit ​​part 311a, a double-pivot rotation structure is formed between the rocker arm 340 and the outer shell 311. At the same time, through the one-line limiting groove 343 provided on the end face of the ball head 341, part of the cam drive shaft 330 can rotate freely within it 360°, thereby driving the rocker arm 340 to reciprocate around the rotating shaft 342 as the fulcrum. In this embodiment, the drive motor 320 is a geared motor, so the speed of the drive motor 320 (300rpm-900rpm) can be converted into the swing force of the bionic tail 200, making its transmission efficiency ≥92%, thus solving the problem of limited swing amplitude in traditional single-pivot transmission.

[0045] Furthermore, by optimizing the angle between the rocker arm 340 and the cam drive shaft 330, a large-amplitude bionic transmission mechanism can be achieved, enabling the sway amplitude of the bionic tail 200 on one side to be ≥65°, and the sway frequency to reach 5-15 times / second. According to fluid dynamics tests, the sway amplitude parameters are more than 90% consistent with the natural tail sway amplitude of target fish species such as crucian carp and perch, thereby significantly improving the bionic realism.

[0046] Please see Figure 6 and Figure 8 Because the bionic tail 200 of the bionic intelligent fish bait will be damaged by fish bites after a period of use, it needs to be replaced. To facilitate the disassembly and replacement of the bionic tail 200, the bionic tail 200 in this embodiment includes an installation section 210 and a tail-wagging section 220. The tail-wagging section 220 is fastened to one end of the installation section 210, and a spherical buckle 211 is provided on the inner wall of the other end of the installation section 210. At the same time, a snap-fit ​​part 311a is located on the tail end of the outer shell 311. The wall is provided with a slot 311b, which is an L-shaped slot. The ball-shaped buckle 211 is inserted into the slot 311b and rotated 45° to lock it into or out of the slot 311b. This enables the assembly and disassembly of the installation section 210 of the bionic tail 200 and the outer shell 311, thus realizing the quick-release structure of the bionic tail 200. This allows for the rapid replacement of a damaged bionic tail 200 within 3 seconds, avoiding the complete scrapping of the bionic smart fish bait due to the damage of a single component, thereby reducing the cost of use.

[0047] In order to ensure the swing effect of the swing section 220, the swing tail section 220 is made of soft rubber with a Shore hardness of 15A-40A, and several staggered dividing grooves 221 are distributed on the left and right sides of the swing tail section 220.

[0048] The tail section 220, made of soft rubber with a Shore hardness of 15A-40A, combined with the wavy guide edge and several staggered grooves 221 on the left and right sides, reduces the water resistance coefficient of the tail section 220 by 30%-40%, reducing energy consumption by more than 25% compared to traditional hard fish tails for the same swing amplitude. Furthermore, the tail section 220 can simulate the flexible deformation of a real fish tail during swinging, enhancing the biomimetic effect and significantly improving endurance. With the same battery capacity (360), the working time of the biomimetic smart fish bait in this embodiment is increased by 30%-50% compared to existing technologies. Simultaneously, the grooves 221 make the biomimetic tail 200 swing more flexibly, further closely resembling the swimming posture of real fish, thereby improving the fish-attracting effect and increasing the success rate of fishing.

[0049] Furthermore, to facilitate the assembly of the bionic tail 200 and reduce the energy consumption of the bionic smart bait, the mounting section 210 in this embodiment is made of plastic, and has connecting drainage holes 212 on its upper and lower sides. The plastic mounting section 210 allows for easy connection to the outer shell 311 and effectively reduces the production cost of the bionic smart bait. Simultaneously, the drainage holes 212 on the upper and lower sides of the mounting section 210 allow the bionic tail 200 to achieve a drainage efficiency of up to 85% during oscillation, utilizing the centrifugal force generated during oscillation. This significantly reduces the dynamic weight of the bionic smart bait by 18%, thereby reducing energy consumption. Finally, through the combined effects of reduced water resistance, reduced energy consumption, and optimized weight, the battery 360's power consumption is further reduced, effectively extending the bionic smart bait's underwater operating time, significantly improving its overall battery life, reducing the frequency of battery replacement or charging, and providing anglers with a longer and smoother user experience, allowing them to enjoy fishing with ease.

[0050] Finally, please see Figure 9 To facilitate the use of the biomimetic intelligent fish bait, connecting rings 120 are respectively provided at the front, top, and bottom of the biomimetic body 100. These connecting rings 120 can be used to connect the fishing line and hook. Through the connecting rings 120 at the front, top, and bottom of the biomimetic body 100, the fishing line can be threaded and fixed from three directions: front, top, and bottom, thus forming a three-dimensional anchor point. Under the impact of a 2m / s water flow or a 5kg pulling force, the detachment rate of the biomimetic intelligent fish bait is reduced by 75% compared to the detachment rate of traditional single-anchor lures, thereby solving the problem of lures being easily lost during fishing. Furthermore, the threading and fixing of the fishing line and the connection of the hook can be adjusted according to the user's needs.

[0051] Furthermore, the bionic body 100 is assembled by two symmetrical half-shells that fit together. The assembly can be done by snap-fit ​​connections, screw connections, or other methods, which allows the bionic body 100 to be quickly closed and facilitates the installation of the drive inner liner 300 into the bionic body 100, thus making it convenient to assemble the entire bionic intelligent fish bait.

[0052] In summary, the biomimetic intelligent fish bait in this embodiment, through the cooperation between the drive motor 320, the cam drive shaft 330, and the swing arm 340, combined with the tail section 220 made of soft rubber, can achieve a single-sided swing amplitude of ≥65° for the biomimetic tail 200 (compared to the single-sided swing amplitude of existing artificial baits which is only 30°-40°), and a swing frequency of 5-15 times / second. This makes the swing amplitude parameters of the biomimetic tail 200 match the natural tail swing amplitude of target fish species such as crucian carp and bass by >90%, thereby significantly improving the biomimetic realism of the intelligent fish bait and enhancing its fish-attracting effect. At the same time, through the water-entry sensing contact 312a and the 3-segment intelligent tail preset on the PCB board 370, it can achieve intelligent energy-saving control of "starting when entering the water and stopping when leaving the water," and can accurately simulate the dynamics of real fish such as patrolling, foraging, and avoiding danger, effectively improving the success rate of trapping and providing anglers with a more comfortable user experience, thereby enhancing the user's fishing enjoyment.
