Description

Technical Field

[0001] This utility model relates to the field of fishing gear technology, specifically an electric drive device for fish bait. Background Technology

[0002] Live fish as bait can effectively mimic natural aquatic life, making them more attractive to target fish. This natural presentation helps increase the success rate of fishing. Live fish can emit a special scent and vibration that can attract surrounding fish, thereby increasing the catch. Live fish bait is suitable for a variety of fish, especially carnivorous fish that like to prey on live prey, such as bass and pike.

[0003] However, live fish used as bait need to be replaced regularly because they will die and lose their appeal, which increases the complexity and cost of fishing. Using live fish as bait requires certain skills and experience. If the placement is incorrect or the operation is improper, the bait may lose its effectiveness or even be wasted. When using live fish as bait, casting becomes difficult because the fish may struggle or twist, especially when using small fish with flat and wide bodies, as air resistance makes it difficult to cast into the intended waters.

[0004] In conclusion, using live fish as fishing bait has unique advantages, but also some obvious disadvantages. To make dead fish wriggle in the water and simulate the movement of live fish, electrically driven bait devices that can be placed inside the fish's belly and make the dead fish's tail wriggle have appeared on the market. However, fishing is a long process, and these products on the market generally suffer from the defect of motors being prone to overheating and damage, and the mechanical noise is relatively loud, leaving considerable room for improvement. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an electric drive device for fish bait.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an electric drive device for fish bait, comprising a sealed outer shell and a rechargeable battery, a control circuit board, and a micro geared motor disposed within the sealed outer shell. A switch device is provided on the outer wall of the sealed outer shell, which is used to control the rotation of the micro geared motor. The micro geared motor is located at one end of the sealed outer shell, and the micro geared motor drives a drive plate disposed at that end to swing back and forth. Thermally conductive silicone pads are respectively placed on both sides of the outer wall of the micro geared motor. The outer surface of each thermally conductive silicone pad is connected to an arc-shaped metal heat-conducting block, and the outer arc surface of each metal heat-conducting block is in close contact with the inner wall of the sealed outer shell.

[0007] Furthermore, each metal heat-conducting block is provided with multiple through holes that extend along the length of the metal heat-conducting block.

[0008] Furthermore, the sealed outer shell is formed by sequentially sealing and connecting the battery shell, circuit shell, and motor shell, with the motor shell made of aluminum alloy and the battery shell and circuit shell made of plastic.

[0009] Furthermore, the output shaft of the micro geared motor passes through the outer end of the motor housing, and a rubber sealing ring is fitted at the part that passes through the motor housing. An eccentric turntable that drives the rotation is fixed at the outer end of the output shaft of the micro geared motor. An eccentric column perpendicular to the end face of the eccentric turntable is provided on one side of the outer end of the eccentric turntable. The rotating end of the drive plate is rotatably set between the clamping plates at the end of the motor housing through a pin shaft, and a sliding groove is provided at the end of the rotating end of the drive plate, with the eccentric column located in the sliding groove.

[0010] Furthermore, the switching device is a touch-sensitive switch and is provided with multiple touch-sensitive contacts. The switching device also has charging contacts for charging the rechargeable battery.

[0011] Furthermore, the battery casing, circuit casing, and motor casing are fixedly connected by waterproof adhesive or threaded structure, and waterproof sealing rings are provided at the connection points of adjacent components.

[0012] Furthermore, a cable tie handle is provided at the outer end of the battery casing.

[0013] Furthermore, a cylindrical protective cover is fitted onto one end of the clamping plate of the motor housing.

[0014] Furthermore, strong magnets are embedded in the surfaces of both ends of the switching device, and these strong magnets are used to magnetically attract the charging head during charging.

[0015] Furthermore, the sealing shell has a cylindrical or square-shaped structure.

[0016] This invention can more realistically drive dead fish to wobble, simulating the swimming motion of live fish, thus better attracting fish, especially carnivorous fish, to bite the bait. Furthermore, since fish may not bite immediately during fishing, the micro-gear motor can overheat after prolonged underwater operation. This invention completely solves the problem of ineffective heat dissipation in micro-gear motors. Through the thermally conductive silicone pads on both sides and the metal heat-conducting block, heat can be quickly conducted to the entire motor housing. The motor housing forms a large heat dissipation area and comes into contact with the fish and the water constantly entering and exiting their bodies, thus achieving excellent heat dissipation and effectively preventing damage to the micro-gear motor due to overheating. Moreover, the micro-gear motor is indirectly connected to the metal heat-conducting block through the soft thermally conductive silicone pads. While the thermally conductive silicone pads dissipate heat, they also provide shock absorption, increase friction for fixation, and reduce noise, preventing noise from affecting fish feeding and increasing the bite rate, thereby increasing the fishing catch.

[0024] The embodiments are described in detail below with reference to the accompanying drawings:

[0025] like Figure 1-5As shown, an electric drive device for fish bait includes a sealed housing 1 and a rechargeable battery 2, a control circuit board 3, and a micro geared motor 4 disposed inside the sealed housing 1. A switch device 5 is provided on the outer wall of the sealed housing 1. The switch device 5 is used to control the rotation of the micro geared motor 4. The micro geared motor 4 is located at one end of the sealed housing 1, and the micro geared motor 4 drives a drive plate 6 disposed at that end to swing back and forth. Thermal conductive silicone pads 7 are respectively placed on both sides of the outer wall of the micro geared motor 4. The outer surface of each thermal conductive silicone pad 7 is connected to an arc-shaped metal heat-conducting block 8. The outer arc surface of each metal heat-conducting block 8 is in close contact with the inner wall of the sealed housing 1, and each metal heat-conducting block 8 is provided with multiple through holes 9 extending along the length of the metal heat-conducting block 8.

[0026] For ease of assembly and installation, the sealed outer shell 1 is formed by sequentially sealing and connecting the battery shell 101, the circuit shell 102, and the motor shell 103. The motor shell 103 is made of aluminum alloy, while the battery shell 101 and the circuit shell 102 are made of plastic. The output shaft of the micro geared motor 4 passes through the outer end of the motor shell 103, and a rubber sealing ring 10 is fitted at the part that passes through the motor shell 103. An eccentric turntable 11 for driving rotation is fixed to the outer end of the output shaft of the micro geared motor 4. An eccentric column 12 perpendicular to the end face of the eccentric turntable 11 is provided on one side of the outer end of the eccentric turntable 11. The rotating end of the drive plate 6 is rotatably set between the clamping plates 13 at the end of the motor shell 103 via a pin. A sliding groove 14 is provided at the end of the rotating end of the drive plate 6, and the eccentric column 12 is located in the sliding groove 14. A cylindrical clamping plate protective cover 18 is fitted on one end of the clamping plate 13 of the motor shell 103 to protect that end.

[0027] The switch device 5 is a touch-sensitive switch and is provided with multiple touch-sensitive contacts. The switch device 5 is also provided with charging contacts 15 for charging the rechargeable battery 2. Strong magnet blocks 19 are embedded in the surfaces of both ends of the switch device 5. The strong magnet blocks 19 are used to magnetically attract the charging head during charging, making it easy to fix during charging, as in the touch switch device used in the prior art.

[0028] The battery housing 101, circuit housing 102 and motor housing 103 are fixedly connected by waterproof glue or threaded structure, and waterproof sealing rings 16 are provided at the connection parts of adjacent two. The outer end of the battery housing 101 is provided with a binding handle 17 to facilitate the passing of fishing line for binding.

[0029] The working principle of this utility model is as follows: the micro geared motor 4 drives the rotating drive plate 6 to swing back and forth, that is, it adopts the current eccentric structure drive, and the working principle is the same as the existing technology. When it is placed in the belly of a fish for fishing, the drive plate 6 extends to the tail of the fish. The switch device 5 senses that the water is connected, and the micro geared motor 4 drives the eccentric turntable 11 to rotate. During the rotation of the eccentric column 12 of the eccentric turntable 11, the eccentric structure continuously drives the rotating end of the drive plate 6 to swing back and forth, thereby driving the part of the drive plate 6 extending to the tail of the fish to swing back and forth, so that the originally dead fish tail forms a swinging effect.

[0030] Furthermore, since fish may not bite immediately during fishing, the micro geared motor 4 may overheat after prolonged underwater operation. This invention completely solves the problem of ineffective heat dissipation in the micro geared motor 4. Thermally conductive silicone pads 7 are placed on both sides of the outer wall of the micro geared motor 4. Each thermally conductive silicone pad 7 has an arc-shaped metal heat-conducting block 8 on its outer surface. The outer arc surface of each metal heat-conducting block 8 is in close contact with the inner wall of the sealing shell 1. The sealing shell 1 consists of a battery shell 101, a circuit shell 102, and a motor shell 103. The motor shell 103 is made of aluminum alloy. The micro geared motor 4 is installed inside the aluminum alloy motor shell 103. Heat can be quickly conducted to the entire motor housing 103 through the thermally conductive silicone pads 7 on both sides and the metal heat-conducting block 8. The motor housing 103 forms a large heat dissipation area and comes into contact with the fish and the water constantly entering and leaving the fish's body, thus forming a good heat dissipation effect. This can effectively prevent the motor of the micro geared motor 4 from being damaged due to overheating. Moreover, the motor of the micro geared motor 4 is indirectly connected to the metal heat-conducting block 8 through the soft thermally conductive silicone pads 7. The thermally conductive silicone pads 7 not only dissipate heat but also have the effects of shock absorption and increased friction fixation, and can also play a certain role in noise reduction, preventing noise from affecting the fish's feeding and hooking, and improving the bite rate when fishing.

[0031] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
