A horizontal axis fishing reel range extender

Abstract

A horizontal axis fishing reel range extender device, which uses precisely controllable electric acceleration and braking to accelerate the spool to a certain initial speed and then start braking in the extremely short period of time from when the hand releases the spool to when the lure flies out and pulls the spool, thereby reducing the kinetic energy loss of the lure on the spool and the fishing line, greatly increasing the casting distance of the lure and ensuring that the line does not explode.

Description

Technical Field

[0001] The invention relates to a fishing tool, in particular to a horizontal axis type fishing reel range extender for lures. Background Art

[0002] When casting lures with horizontal axis reels, such as water drop reels and drum reels, the lure needs to drive the spool in the reel and the fishing line around the spool to rotate at high speed, causing part of the kinetic energy of the lure to be converted into the rotational kinetic energy of the spool and the fishing line, thus affecting the casting distance of the lure. For most horizontal axis reels on the market, when casting small lures weighing less than 10g, the kinetic energy loss consumed by the spool and the fishing line generally reaches more than 50%, seriously affecting the casting distance of small lures.

[0003] In order to increase the casting distance of lures, various manufacturers have two main directions of effort: First, according to the rotational kinetic energy formula

[0004] E=0.5*I*ω 2

[0005] Where: I—the moment of inertia of the spool and the fishing line

[0006] ω—Angular velocity of the spool and the fishing line

[0007] Through lightweight design and selection of the optimal spool radius value, the product of the spool's moment of inertia and the square of the spool's angular velocity can be reduced, thereby reducing the initial kinetic energy loss of the lure and increasing the casting distance.

[0008] Another reason is that the flight of the lure is an oblique throwing motion, and its flight speed first decreases and then increases. Correspondingly, the spool must slow down under the action of the braking force in the first half of the lure's flight to match the lure's flight speed (otherwise, the fishing line will first relax on the spool and then get stuck, commonly known as "line explosion"). In the second half, the lure accelerates and flies obliquely downward, and the braking force required by the spool is much smaller than that in the first half, or even completely unnecessary. In short, too much braking force will cause kinetic energy loss during the lure's flight, while too little braking force will cause the line to explode and the lure will be unable to continue flying. Therefore, making the braking force dynamically match the lure's flight state is another effort of various manufacturers to increase the casting distance of lures.

[0009] However, today when fishing reels have become very mature, none of the above methods can improve the casting distance of the lure qualitatively. Summary of the invention

[0010] In view of the fact that the kinetic energy loss of the lure in the line cup and the fishing line exceeds 50% when casting, the present invention uses a form of precisely controllable electric acceleration and braking. During casting, the line cup is accelerated to a certain initial rotation speed (the most ideal state is that the linear speed of the outermost fishing line is very close to the initial speed of the lure before pulling the line cup) and then braking is started, thereby reducing the kinetic energy loss of the lure in the line cup and the fishing line (the most ideal state is reduced to close to zero), greatly improving the casting distance of the lure (the maximum can be increased to more than 2 times) and ensuring that the line does not explode.

DETAILED DESCRIPTION

[0012] The present invention is composed of three major parts, namely, a power supply system (1), a motor (2), and a control system (3). The power supply system (1) is composed of a power supply (11) and a power switch (12). The motor (2) is a high-speed hollow cup motor (only a few volts of working voltage are required to reach tens of thousands of revolutions per minute at no load), and its rotating shaft is connected to the spool shaft of the fishing reel to serve as an acceleration and braking device for the spool. The control system (3) is composed of a delay circuit (31), a relay (32), an adjustable resistor (33), a display screen (34), a setting button (35), a trigger button (36), etc. The delay circuit (31) is composed of MOS tubes and the like, and is used to control the on-off time of the relay (32) (with an accuracy of 0.01 seconds). The working mode of the delay circuit (31) in the present invention is: a signal is given, the system is in standby mode—the signal disappears, the task is triggered, and the relay (32) is reset after being energized for a set time; the relay (32) is controlled by the delay circuit (31), and its output has three ports: "normally closed", "common", and "normally open". When not receiving an instruction from the delay circuit (31), the "common" terminal is in contact with the "normally open" terminal. The "normally closed" end is connected and disconnected from the "normally open" end - when it receives an instruction from the delay circuit (31), the "common" end is disconnected from the "normally closed" end and turned to be connected to the "normally open" end until the instruction disappears and it returns to its original state; the display screen (34) is used to display the acceleration gear, and the gear value is related to the pull-in time of the relay (32); the setting button (35) is used to set the acceleration gear, that is, the pull-in time of the relay (32); the trigger button (36) is a light touch button, and its working mode is to turn on when pressed and disconnect when released.

[0013] The power switch (12) and the trigger button (36) of the present invention are integrated on the line outlet switch of the fishing reel. When the line outlet switch is pressed (an operation before casting the lure), the line end contacts of the power switch (12) and the trigger button (36) are in contact. At this time, the wiring of the two is in a conducting state, the range extension system is powered on, and the trigger button (36) is also in a signal output state due to being pressed by the thumb of the user (the user's thumb will press the line cup at the same time). When the user swings the rod to cast to a suitable angle, the thumb is released, the signal given by the trigger button (36) disappears and a pulse (delay circuit start instruction) is formed. The delay circuit (31) sends a set instruction to the relay (32), and the range extension system starts to work. After casting is completed, the user shakes the fishing reel reel reel handle, the line outlet switch pops up, and the entire range extension system is in a power-off state, thereby achieving the purpose of power saving.

[0014] The composition and relationship diagram of the present invention are as follows Figure 2 As shown. The positive and negative poles of the power input of the delay circuit (31) are respectively connected to the positive and negative poles of the power system (1), the negative pole of the signal input is connected to the negative pole of the power system (1), and the positive pole of the signal input is connected in series with the trigger button (36) and the positive pole of the power system (1); one pole of the negative pole of the motor (2) is connected to the negative pole of the power system (1), and the other pole is connected in series with the adjustable resistor (33) and the "normally closed" end of the relay (32); the positive pole of the motor (2) is connected to the "common" end of the relay (32); and the "normally open" end of the relay (32) is connected to the positive pole of the power system (1). When the user casts and releases the thumb, the signal of the trigger button (36) disappears, and the relay (32) works for a set time period under the instruction of the delay circuit (31). During this period, the "common" end and the "normally open" end are connected, and the power supply system (1) and the motor (2) form an acceleration circuit through the relay (32). The range extension system is in an acceleration state, and the spool is accelerated to a certain speed. After the set time period, the instruction of the delay circuit (31) disappears, the "common" end of the relay (32) is turned to be connected to the "normally closed" end, and the motor (2) and the adjustable resistor (33) form a braking circuit through the relay (32). At this time, the motor (2) is driven by the spool, and its coil cuts the magnetic field to form a current and generate electromagnetic resistance, which then produces a braking effect on the spool. The user obtains different electric acceleration effects by setting the acceleration gear (the pull-in time of the relay (32)), and changes the induced current of the motor (2) by adjusting the resistance value of the adjustable resistor (33) to obtain different braking effects.
