Description

Technical Field

[0001] The utility model relates to the technical field of fishing tackle products, in particular to an electronic brake gear adjustment mechanism for a fishing reel. Background Art

[0002] The electronic brake system of a fishing reel controls the rotational resistance of the spool through electromagnetic force, effectively preventing the fishing line from tangling during casting, and has become the core technology of modern fishing reels. Currently, the mainstream electronic brake devices mainly adopt a resistive gear adjustment structure and a magnetic induction stepless adjustment structure.

[0003] The resistive gear adjustment structure changes the input current by rotating a potentiometer and adjusts the braking force using a variable resistance value. It has the following defects: the potentiometer contacts are prone to wear and oxidation, resulting in poor contact and gear failure; the step change of the resistance value leads to discontinuous adjustment of the braking force and cannot achieve fine control; the mechanical structure is complex and the failure rate is high.

[0004] The magnetic induction stepless adjustment structure is provided with multi-pole magnets on a rotating magnetic ring, and the continuous adjustment of the braking force is realized by detecting the angle change of the magnetic ring through a Hall sensor. It has the following defects: it is greatly affected by assembly tolerances and the control accuracy is low; the radial gap between the magnetic ring and the sensor is easily affected by vibration, resulting in signal drift. Summary of the Utility Model

[0005] Aiming at the problems existing in the above-mentioned prior art, the utility model provides an electronic brake gear adjustment mechanism for a fishing reel, which optimizes the operation mode of braking force adjustment and realizes convenient and accurate braking force adjustment.

[0006] The technical solution adopted by the present utility model is as follows: An electronic brake gear adjustment mechanism for a fishing reel, comprising a mounting base and a spool seat connected to the mounting base. A control circuit board is installed in the inner cavity formed by the mounting base and the spool seat. It is characterized in that: it further comprises a lifting guide rail device and a lifting guide claw; the lifting guide rail device is rotatably arranged above the spool seat, and its upper end is connected to a gear knob assembly, and the gear knob assembly is used to drive the lifting guide rail device to rotate; a spiral guide rail is arranged on the outer wall of the lifting guide rail device; the lower part of the lifting guide claw is located in the inner cavity formed by the mounting base and the spool seat and above the control circuit board. A sensing magnet A is fixedly connected to the lower part of the lifting guide claw. A magnetic induction element is arranged on the control circuit board at a position corresponding to the sensing magnet A; the upper part of the lifting guide claw extends out of the spool seat and is provided with a "7"-shaped hook part, and the "7"-shaped hook part is placed on the spiral guide rail. By rotating the gear knob assembly to drive the lifting guide rail device to rotate, the spiral guide rail drives the lifting guide claw and the sensing magnet A to vertically lift and lower. The control circuit board adjusts the energizing current intensity of the coil assembly according to the change of the magnetic induction signal caused by the change of the distance between the sensing magnet A and the magnetic induction element to realize the adjustment of the braking force magnitude.

[0007] Further, the spiral guide rail is a continuous spiral convex rail or a spiral groove arranged on the outer wall of the lifting guide rail device.

[0008] Further, a limiting seat is arranged at the lower part of the lifting guide claw, and a limiting hole extending in the vertical direction is opened on the limiting seat. A guide post matched with the limiting hole is arranged in the mounting base to restrict the lifting guide claw to only make vertical lifting and lowering movements without rotation.

[0009] Further, the lifting guide rail device is a columnar hollow structure; a first cylindrical boss is arranged at the top of the spool seat; the lifting guide rail device is rotatably sleeved on the first cylindrical boss.

[0010] Further, a second cylindrical boss is coaxially arranged at the upper end of the first cylindrical boss, and the diameter of the second cylindrical boss is smaller than that of the first cylindrical boss; a sleeve is arranged on the bottom surface of the gear knob assembly, and the sleeve is sleeved on the second cylindrical boss; a first limiting block is fixedly arranged on the upper end surface of the first cylindrical boss; a second limiting block is arranged on the bottom surface of the gear knob assembly; when the gear knob assembly rotates, the rotation angle range of the gear knob assembly is restricted by the abutment of the first limiting block and the second limiting block.

[0011] Further, an outer cover is detachably connected to the spool seat.

[0012] Furthermore, the spiral guide rail on the outer wall of the lifting guide rail device includes a first straight section located below, a second straight section located above, and a spiral section connecting the first straight section and the second straight section; a fixed seat is arranged between the first straight section and the second straight section on the outer wall of the lifting guide rail device, and an induction magnet B is installed in the fixed seat; when the "7"-shaped hook part of the lifting guide claw is located on the first straight section or the second straight section, rotating the lifting guide rail device will not drive the lifting guide claw to vertically displace. At this time, the control circuit board adjusts the energizing current of the coil assembly according to the change in the distance between the induction magnet B and the magnetic induction element caused by the rotation angle of the lifting guide rail device.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) Through the ingenious cooperation of the lifting guide rail device, the lifting guide claw, the induction magnet A and the magnetic induction element, when the rotating gear knob assembly drives the lifting guide rail device to rotate, the spiral guide rail drives the lifting guide claw and the induction magnet A to vertically lift and lower. The distance between the induction magnet A and the magnetic induction element changes continuously and controllably. This change enables the control circuit board to obtain the change of the magnetic induction signal in real time and accurately, and then precisely adjust the energizing current intensity of the coil assembly, realizing the refined and stepless adjustment of the braking force size, meeting the diverse requirements of different fishing scenarios for the braking force, and greatly improving the accuracy and flexibility of the braking force adjustment; using the mechanical coupling drive of the spiral guide rail and the lifting guide claw to replace the traditional potentiometer contact, eliminating the contact friction loss and avoiding the problem of resistance-based gear failure;

[0015] (2) Through the special design of the first straight section, the spiral section and the second straight section of the spiral guide rail, and in cooperation with the induction magnet B, the adjustment drawbacks of the prior art under space constraints are effectively overcome; when the "7"-shaped hook part of the lifting guide claw is in the first straight section or the second straight section, rotating the lifting guide rail device will not drive the lifting guide claw to vertically displace. At this time, the control circuit board adjusts the energizing current of the coil assembly according to the change in the distance between the induction magnet B and the magnetic induction element caused by the rotation angle of the lifting guide rail device. This design makes ingenious use of the position change of the induction magnet B to realize the preliminary adjustment of the braking force without changing the height of the lifting guide claw; and for the middle spiral section, since there is no need to consider the requirement of large-range angle adjustment, its angle can be appropriately increased. When the "7"-shaped hook part of the lifting guide claw is in the spiral section, the larger-angle spiral structure can make the lifting guide claw and the induction magnet A generate a larger vertical displacement at a smaller rotation angle, thereby causing a more significant change in the distance between the induction magnet A and the magnetic induction element. This enables the control circuit board to make a more refined adjustment of the braking force, realizing the differential requirements of the braking force adjustment in different stages.
