Description

Technical Field

[0001] This invention relates to the field of fishing reels, and more particularly to a method for simulating the displacement rate of a fishing reel. Background Technology

[0002] Fishing reels use spools to wind the line during the reeling process. Since the spools reciprocate, the inconsistent speed of the spools during winding can easily result in a wavy line, either larger at the top and smaller at the bottom, or vice versa. To achieve a smoother line, it is necessary to understand the spool displacement rate. By designing a sliding rail to alter the spool displacement rate, the return stroke at both ends of the spool is accelerated while the middle section is slowed down, resulting in a smoother line. Therefore, a method for simulating the spool displacement rate is required. Summary of the Invention

[0003] This invention addresses the existing problems by proposing a method for simulating the displacement rate of a linear wheel.

[0004] A method for simulating the displacement rate of a linear wheel includes the following steps: Step 0: Establish a coordinate system and import the action arc and the slider; Step 1: Obtain the travel distance between the two action arcs; Step 2: Decompose the action arc into R0, R1, and R2; Step 3: Obtain the slider radius OD; Step 4: Set the slider displacement distance Y; Step 5: Obtain the offset angle between the slider and the center of one of the action arcs; Step 6: Calculate the coordinates (CENX0, CENY0), (CENX1, CENY1), and (CENX2, CENY0) of the three action arcs R0, R1, and R2 with respect to the center of the slider circle. Step 7: Calculate the coordinates of the intersection points (inpx0, inpy0) and (inpx2, inpy1) between the action arcs; Step 8: Take P(x0, y0) on the slider and determine the area where y0 is located; Step 9: Calculate the displacement value Q of point P in the time interval t; Step 10: Calculate the instantaneous velocity using Q / t; Step 11: Repeat step 9 until the slider completes the back-and-forth movement; Step 12: Combine all instantaneous velocities into a velocity curve; Step 13: Merge the lift curve and the return curve to simulate the wheel displacement rate curve.

[0005] Preferably, in step 8, the active arc is determined to be R0, R1 or R2 based on the location of y0, and then the center coordinates (CENX0, CENY0), (CENX1, CENY1) or (CENX2, CENY2) corresponding to the active arc R0, R1 or R2 are taken.

[0006] Preferably, in step 9, the offset angle of the slider displacement is t*180°, and when t=0, the slider is at the lowest point of the displacement path.

[0007] Preferably, in step 12, with point P as the focus, the displacement value M of point P is calculated based on the offset angle of the slider displacement during the time period t0 to t1, and the instantaneous velocity during this time period t0 to t1 is M / (t1-t0).

[0008] The beneficial effects achieved by the simulation method for the displacement rate of the threaded wheel provided by this invention are as follows:

[0009] This method imports the action arc of the wheel path and the coordinates of the slider into a coordinate system. The center coordinates of the action arc are obtained by using R0, R1, R2, OD and forming Y. Then, the slider is located on which action arc during its movement. The instantaneous displacement of the slider is calculated by determining the action arc and monitoring point P. Finally, the instantaneous velocity is calculated and the set of instantaneous velocities is used to simulate the wheel displacement rate curve, thereby improving the slider and displacement path.

[0018] The following description, in conjunction with the accompanying drawings, further illustrates the method for simulating the displacement rate of a wheel provided by the present invention. It should be noted that the technical solution and design principle of the present invention will be described in detail below using only one optimized technical solution.

[0019] Throughout the description of this invention, it should be noted that directional terms such as "center," "lateral," "longitudinal," "sideways," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate directions and positional relationships based on the accompanying drawings or terms commonly used by those skilled in the art. These terms are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific scope of protection of this invention.

[0020] First, refer to Figure 1 During the reciprocating movement of the thread reel, the thread reel passes through Figure 1 The guide block and the slider move in the hollow path of the guide block, thereby driving the spool to reciprocate. During the reciprocating motion of the spool, since the rotation speed of the spool can be regarded as constant, but the winding speed remains constant when the spool goes back and forth to the two ends, the amount of winding will accumulate, causing the line shape to change. Therefore, it is necessary to control the speed of the spool when it goes back and forth by setting the path. In order to intuitively show the speed of the spool going back and forth, the following steps are proposed.

[0021] Step 0: Establish a coordinate system and import the active arc and slider;

[0022] Step 1: Combining Figure 2 , to obtain the travel distance between the two active arcs;

[0023] Step 2: Combining Figure 2 The effective arc is specifically divided into R0, R1, and R2;

[0024] Step 3: Combining Figure 2 Obtain the slider radius OD;

[0025] Step 4: Combining Figure 2 Set the slider displacement distance Y;

[0026] Step 5: Combining Figure 2 The offset angle between the slider and the center of the arc is obtained by using one of the arc centers of the arc.

[0027] Step 6, combined Figure 3 Calculate the coordinates (CENX0, CENY0), (CENX1, CENY1), and (CENX2, CENY2) of the action arcs R0, R1, and R2 with respect to the center of the slider circle, respectively.

[0028] Step 7, combined Figure 4Calculate the coordinates of the intersection points (inpx0, inpy0) and (inpx2, inpy1) of the action arc;

[0029] Step 8, combined Figure 5 Take P(x0, y0) on the slider and determine the region where y0 is located;

[0030] Step 9, combined Figure 6 and Figure 7 Calculate the displacement Q of point P during time interval t;

[0031] Step 10, combined Figure 7 The instantaneous velocity is calculated using Q / t;

[0032] Step 11, repeat until step 9, until the slider has moved back and forth;

[0033] Step 12: Combine all instantaneous velocities to form a velocity curve;

[0034] Step 13, combined Figure 8 The lift curve and return curve are combined to simulate the sheave displacement rate curve. Curve A is the sheave movement rate curve during lift, curve B is the line movement rate curve during return, and curve C is the combined sheave movement rate curve. Users can judge whether the sheave winding under this parameter design is smooth by observing the speed of the sheave back and forth at both ends in region D. It can be understood that in this embodiment, the closer the peak value in region D is to the value at the smooth end, the smoother the winding is.

[0035] This method imports the action arc of the wheel path and the coordinates of the slider into a coordinate system. The center coordinates of the action arc are obtained by using R0, R1, R2, OD and forming Y. Then, the slider is located on which action arc during its movement. The instantaneous displacement of the slider is calculated by determining the action arc and monitoring point P. Finally, the instantaneous velocity is calculated and the set of instantaneous velocities is used to simulate the wheel displacement rate curve, thereby improving the slider and displacement path.

[0036] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be considered as limitations on the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
