Description

Technical Field

[0001] The invention generally relates to a control device for a water drop reel in the field of lure fishing. Background Art

[0002] In lure fishing, the water drop reel has become one of the most commonly used reels due to its cool appearance, high casting accuracy, small size, etc.; the biggest disadvantage of the water drop reel is that when the line out of the spool is faster than the flying speed of the lure, the fishing line can easily be tangled in the water drop reel, which is commonly known as fried line or fried noodles; in order to overcome this disadvantage, various brake devices were born. The current mainstream ones are centrifugal brakes, electromagnetic brakes, hybrid brakes evolved from centrifugal brakes and electromagnetic brakes, and electronic brakes. The principle of centrifugal brakes is to use the centrifugal force generated by the brake beans when they rotate at high speed to throw the brake beans out and rub against the spool to release the brake beans. The electromagnetic brake uses the closed loop formed by the metal spool to cut the magnetic lines of force and generate a reverse electromagnetic force to reduce the spool speed; the electronic brake uses a sensor to detect the spool speed and adjust the current in real time to control the electromagnetic force. Although these brake devices have different methods, they all belong to open-loop control systems. The size of the braking force is only related to the spool speed, and it does not reflect the difference between the spool line output speed and the flight speed of the lure. At the end of the cast, when the spool speed is low, the braking force is almost zero, and manual control is required to stop the spool from rotating. Otherwise, the fishing line will easily accumulate on the spool and cause the line to explode. Summary of the Invention

Implementation Method

[0022] like Figures 1-3As shown: the brake device of the present invention is a closed control system. The friction between the brake pad 721 on the elastic brake pad 7 and the rubber ring 2 is the braking force of the brake device. The reducer I is subjected to three torques, namely, a counterclockwise torque T1 applied by the fishing line 9 to the pull rod 311, a counterclockwise torque T2 caused by the force of the rubber ring on the elastic brake pad 7, and a clockwise torque T3 with an absolute value greater than zero applied by the torsion spring 6 to the output gear I 4. When (T1+T2+T When (T1+T2+T3) is less than 0, the reducer I rotates clockwise and drives the pull rod 311 to rotate clockwise; when (T1+T2+T3)=0, the reducer I is stationary; when the speed of the lure 14 is greater than the speed of the spool, the fishing line 9 becomes tight, the pull rod 311 rotates counterclockwise and drives the output gear I 4 of the reducer I to rotate counterclockwise, the pressure of the brake pad 721 on the rubber ring 2 becomes smaller, the friction becomes smaller, and the spool The pulling force of the fishing line 9 on the spool is greater than the braking force, that is, the acceleration of the spool is positive, the spool speed increases, and the speeds of the spool and the lure 14 quickly converge to the same speed; when the speed of the lure 14 is less than the spool line release speed, the fishing line 9 becomes slack, the output gear Ⅰ4 of the reducer Ⅰ rotates clockwise, the pressure of the brake pad 721 on the rubber ring 2 increases, and the friction force increases. The pulling force of the fishing line 9 on the spool is less than the braking force, that is, the acceleration of the spool is negative, the spool speed slows down, and the speeds of the spool and the lure 14 quickly converge to the same speed; in extreme cases, the speed difference between the spool and the lure 14 is too large. When the braking force alone is insufficient to quickly converge the line-releasing speed of the spool and the speed of the lure 14, the reducer I continues to rotate clockwise under the action of the torsion spring 6, and the pawl 51 on the double gear 5 continuously approaches the ratchet 1 on the spool and eventually engages. At the moment the pawl 51 and the ratchet 1 engage, the pulling force of the pawl 51 on the ratchet 1 is infinite relative to the water drop reel, which can stop the rotation of the spool instantly and avoid line breaking. To ensure that the pawl 51 and the ratchet 1 can engage, the minimum value of T3 must be greater than the maximum value of T2.

[0023] like Figures 4 to 12As shown: This embodiment includes a reducer I, an elastic brake pad 7, a torsion spring 6, a spool, and a reducer II, wherein the reducer I is a two-stage reducer, which includes an input gear I3, an output gear I4, and a double gear I5, wherein the input gear I3 is provided with a connecting rod 31, the end of the connecting rod 31 is provided with a pull rod 311, the output gear I4 is provided with a positioning pin 41, and the double gear I5 is provided with a pawl 51; an elastic brake pad 7 is installed on the column 8 where the output gear I4 is located; the output gear I4 and the elastic brake pad 7 are matched through the positioning hole 71 and the positioning pin 41 to achieve synchronous rotation; the torsion spring 6 is installed on the column 8 where the output gear I4 is located On the upper part, the free arm I61 of the torsion spring 6 is pressed on the output gear I4, and the free arm II62 is stuck in the positioning hole II111 of the output gear II11; a circular groove is provided on the outer cylinder of the spool close to the reducer I side, on which a rubber ring 2 is installed, and a ratchet 1 is provided on the side wall of the spool close to the reducer I side; a positioning hole I71 and a spring 72 are provided on the elastic brake pad 7, and a brake pad 721 is provided at the end of the spring 72; a positioning hole II111 is provided on the output gear II11 of the reducer II for fixing the free arm II62 of the torsion spring 6, and a knob 12 is provided on the input gear II10 of the reducer II for adjusting the initial torque of the torsion spring 6.

[0024] like Figure 8 As shown in the figure: the X-axis is the angle through which the pull rod 311 rotates, wherein the origin is the position of the pull rod 311 when the fishing line 9 below the pull rod 311 is stretched into a straight line, i.e., the origin; A1 is the angle through which the pull rod 311 rotates from the origin when the brake pad 721 and the rubber ring 2 begin to contact at the critical point; A2 is the angle through which the pull rod 311 rotates from the origin after the pawl 51 and the ratchet 1 are engaged; and the Y-axis is the braking force of the present brake device; the curvature of the curve in the figure is determined by the thickness, width and material of the elastic brake pad 7, and different curve curvatures can be obtained by replacing different elastic brake pads 7.

[0025] The braking force is directly proportional to the reduction ratio of reducer I, the lever arm of the pull rod, the friction coefficient between the brake pad 721 and the rubber ring 2, and inversely proportional to the lever arm of the brake pad 721. When the tension of the fishing line 9 increases, the increase in braking force is: (reduction ratio of reducer I × lever arm of the pull rod × friction coefficient between the brake pad 721 and the rubber ring 2) / lever arm of the brake pad 721.

[0026] The simple method of using the present invention is as follows: according to the weight of the lure 14 used, an appropriate elastic brake pad 7 is selected and installed, the lure 14 is hung on the fishing line 9 and suspended in the air, and then the knob 12 is turned to control the torque of the torsion spring 6 so that the fishing line 9 below the pull rod 311 is roughly stretched into a straight line. Then, the lure 14 is placed on the ground to completely relax the fishing line 9. At this time, as long as the pawl 51 and the ratchet 1 can be fully engaged, the fishing line 9 can be completely relaxed.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are merely preferred embodiments of the present invention.
