[0034] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please see attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5The embodiment of the present invention provides a pickle ball training device and system, including an L-shaped bracket 1, a movement mechanism 2 is arranged at the rear of the L-shaped bracket 1, a positioning mechanism 3 is arranged at the bottom of the L-shaped bracket 1, an H-shaped movable frame 4 is slidably connected to the front of the L-shaped bracket 1, a base plate 5 is slidably connected inside the H-shaped movable frame 4, a vibration detection touch sensor module 6 is arranged at the middle of the front end of the base plate 5, which is used to record the number of hits when the pickle ball hits, ultra-thin pressure detection sensor modules 7 are arranged on both sides of the front end of the base plate 5, which are used to collect and measure the pressure when the pickle ball hits, and a display panel 8 is arranged at the top of the front end of the base plate 5;

[0036] The motion mechanism 2 includes a driving bin 201, the front end of which is slidably connected to the rear end of the base plate 5, the rear end of the driving bin 201 is fixedly connected to a servo motor 202, the output end of the servo motor 202 passes through the driving bin 201 and is fixedly connected to a transmission rod 203, an incomplete gear 1 204 is fixedly connected to the front outer side of the transmission rod 203, a tooth plate 205 is meshed with the outer side of the incomplete gear 1 204, both ends of the tooth plate 205 are fixedly connected to L-shaped plates 206, and the front ends of the L-shaped plates 206 on both sides are fixedly connected to the rear end of the base plate 5.

[0037] The H-shaped movable frame 4 can guide the movement direction of the substrate 5 to prevent the substrate 5 from deflecting after being subjected to force, and then the substrate 5 can be used to provide support for the vibration detection touch sensor module 6, the ultra-thin pressure detection sensor module 7, and the display panel 8. The vibration detection touch sensor module 6, the ultra-thin pressure detection sensor module 7, and the display panel 8 transmit electrical signals through the line, so that the number of pickle ball collisions and the collision pressure detected by the vibration detection touch sensor module 6 and the ultra-thin pressure detection sensor module 7 can be displayed on the display panel 8 in a timely manner. In addition, the servo motor 202 can drive the transmission rod 203 to rotate under the support of the driving compartment 201, and then the incomplete gear 1 204 can be rotated synchronously through the transmission rod 203. Only part of the outer side of the incomplete gear 204 has convex teeth, and corresponding convex teeth are present on both sides of the toothed plate 205 meshing with it. Therefore, when the incomplete gear 204 rotates unidirectionally, it can mesh with the convex teeth on both sides of the toothed plate 205 in turn to drive the toothed plate 205 to move up and down. Then, through the through grooves pre-opened on both sides of the driving bin 201, the L-shaped plate 206 can drive the base plate 5 to move synchronously along the H-shaped movable frame 4 and the driving bin 201 with the movement of the toothed plate 205, so as to achieve the purpose of adjusting the position of the base plate 5 in the vertical direction, thereby avoiding the formation of muscle memory when the trainees hit the pickleball at the base plate 5 within a fixed range for a long time, and further, the actual combat effect can be more realistically simulated by changing the position of the base plate 5.

[0038] Please see attached Figure 4 and attached Figure 5The front end of the transmission rod 203 is rotatably connected to the front end of the driving bin 201, and both sides of the bottom of the tooth plate 205 are penetrated by limit rods 207, and the bottom ends of the limit rods 207 on both sides are fixedly connected to the front of the bottom end of the driving bin 201.

[0039] The front end of the transmission rod 203 can be supported by the driving bin 201 to prevent the incomplete gear 204 from deflecting or shifting with the transmission rod 203. At the same time, the movement direction of the tooth plate 205 can be guided by the limit rod 207 to ensure that the incomplete gear 204 and the tooth plate 205 can always remain in meshing.

[0040] Please see attached Figure 2 , Attachment Figure 4 , Attachment Figure 6 and attached Figure 7 The motion mechanism 2 also includes an incomplete gear 208, the middle part of the incomplete gear 208 is fixedly connected to the middle part of the outer side of the transmission rod 203, the top of the incomplete gear 208 is meshed with a transmission gear 209, the rear end of the transmission gear 209 is rotatably connected to a protruding rod 210, the inside of the protruding rod 210 is rotatably connected to a rotating plate 211, the rear end of the rotating plate 211 is rotatably connected to the upper rear end of the L-shaped bracket 1, the front end of the transmission gear 209 is rotatably connected to a vertical plate 212, the two ends of the vertical plate 212 are respectively fixedly connected to the upper parts of both sides of the driving bin 201, the front part of the bottom end of the driving bin 201 is fixedly connected to a horizontal plate 213, and both sides of the front end of the horizontal plate 213 are fixedly connected to the rear end of the H-shaped movable frame 4.

[0041] The transmission rod 203 can also drive the incomplete gear 208 to rotate. Since only part of the surface of the incomplete gear 208 has convex teeth, the transmission gear 209 can rotate intermittently when the transmission rod 203 and the incomplete gear 208 rotate continuously. At this time, the convex rod 210 located at the eccentric position of the rear surface of the transmission gear 209 can rotate accordingly, and then the convex rod 210 can be used to apply a force to the front area of ​​the rotating plate 211 that moves with the convex rod 210. However, since the length of the rotating plate 211 is fixed and connected to the L-shaped bracket 1, when the convex rod 210 rotates intermittently, the rotating plate 211 11 can intermittently swing with a certain amplitude. On the contrary, when the rotating plate 211 swings, it can apply a thrust to the transmission gear 209 through the protruding rod 210, and the vertical plate 212 supporting the transmission gear 209 can make the driving chamber 201 apply a thrust to the H-shaped movable frame 4 through the horizontal plate 213, so as to achieve the purpose of driving the H-shaped movable frame 4, the base plate 5, the driving chamber 201, etc. to move back and forth in the horizontal direction along the L-shaped bracket 1 through the swing of the rotating plate 211, thereby enriching the movement range of the base plate 5 in space, and further improving the authenticity of hitting the pickle ball to the base plate 5 for simulated battle.

[0042] Please see attached Figure 4 -Attached Figure 6The front end of the incomplete gear 208 is rotatably connected to the outer side of the front end thereof with a connecting ring 214 , and the front end of the connecting ring 214 is rotatably connected to the outer side of the rear end of the incomplete gear 1 204 .

[0043] The connecting ring 214 can ensure that the incomplete gear 2 208 and the incomplete gear 1 204 will not move closer or farther from each other, and at the same time improve the stability of the incomplete gear 2 208 and the incomplete gear 1 204 during movement.

[0044] Please see attached Figure 7 The outer side of the protruding rod 210 is rotatably connected with a round table 215, and the front end of the round table 215 is fixedly connected to the rear end of the transmission gear 209.

[0045] The truncated cone 215 can increase the contact area between the protruding rod 210 and the transmission gear 209 to prevent the contact portion thereof from being subjected to excessive force and breaking. At the same time, the position of the transmission gear 209 can be limited when the protruding rod 210 is subjected to force and rotates around the contact portion thereof with the transmission gear 209.

[0046] Please see attached Figure 3 A plurality of hollow cylinders 216 are fixedly connected to the rear end of the L-shaped bracket 1, and guide rods 217 are slidably connected inside the plurality of hollow cylinders 216. The front ends of the guide rods 217 are fixedly connected to the four corners of the rear end of the base plate 5 respectively.

[0047] The evenly distributed hollow cylinders 216 and guide rods 217 ensure that the H-shaped movable frame 4, the base plate 5 and the L-shaped bracket 1 can only move forward and backward in the horizontal direction, thereby improving the stability of their respective movements.

[0048] Please see attached Figure 2 , Attachment Figure 3 , Attachment Figure 6 and attached Figure 7 The positioning mechanism 3 includes a lower pressure frame 301, which is arranged in the lower part of the L-shaped bracket 1. The top of the lower pressure frame 301 passes through the driving bin 201 and is fixedly connected with an arc plate 1 302. The outer side of the rear end of the incomplete gear 208 is slidably connected with a plurality of arc plates 2 303. The bottom end of the lower pressure frame 301 passes through the L-shaped bracket 1 and is slidably connected with a concave plate 304.

[0049] The rotation of the incomplete gear 208 can utilize centrifugal force to move the evenly distributed arc plate 2 303 to the side away from the transmission rod 203, and then utilize the contact between the multiple arc plates 2 303 and the arc plate 1 302 to enable the arc plate 1 302 to drive the lower pressure frame 301 to move downward along the driving bin 201 and the L-shaped bracket 1, so that the concave plate 304 can be pressed to the ground. At this time, the texture on the bottom surface of the concave plate 304 and the pressure it receives can be used to enhance the friction between the L-shaped bracket 1 and the ground, thereby preventing the H-shaped movable frame 4 and the L-shaped bracket 1 from being significantly displaced under the cooperation of the wheels at the bottom when the trainer hits the pickle ball to the base plate 5, and further avoids the need for the trainer to pause training to adjust the positions of the L-shaped bracket 1, the H-shaped movable frame 4, the base plate 5, etc.

[0050] Please see attached Figure 3 , Attachment Figure 6 and attached Figure 7 The four corners of the top of the concave plate 304 are fixedly connected to the limiting rod 2 305, and the tops of multiple limiting rods 2 305 all pass through the L-shaped bracket 1. The outer side of the lower pressure frame 301 is fixedly connected to a connecting plate 306, and the bottom end of the connecting plate 306 is fixedly connected to a spring 307, and the bottom end of the spring 307 is fixedly connected to the rear part of the bottom end of the driving bin 201.

[0051] The position of the concave plate 304 can be limited by the evenly distributed limiting rods 305 to ensure that the concave plate 304 can only move in the vertical direction. The connecting plate 306 and the spring 307 can drive the concave plate 304 off the ground through the pressing frame 301 when the arc plate 1 302 is not affected by the arc plate 2 303, so as to prevent the concave plate 304 from excessively rubbing along the ground when the L-shaped bracket 1 and the H-shaped movable frame 4 are moved.

[0052] Please see attached Figure 8 , a pickleball training system, including the following modules:

[0053] Substrate motion module: Based on the needs of pickleball training, the spatial coordinate position of the substrate in each time period is adjusted through the preset motion program of the host, and the displacement amplitude in the horizontal and vertical directions is divided. The spatial coordinate position of the substrate after movement can be determined through different displacement amplitudes in the horizontal and vertical directions; the spatial displacement speed of the substrate is adjusted in combination with the technical level of each trainee. When the substrate is in motion, the reaction ability of the trainee is exercised through different spatial displacement speeds of the substrate. The corresponding substrate spatial displacement speed needs to be matched according to the level of each trainee; a spatial coordinate configuration table is generated, which is a collection of various spatial coordinate positions reached during the movement of the substrate.

[0054] Hit counting module: Based on the spatial coordinate configuration table, the vibration detection sensor module collects vibration signals in each time period, calculates signal attenuation, and removes interference signals through cleaning and interpolation and supplements them. Generates an effective count initial table based on the strength and range of the vibration signal. According to the current spatial coordinates of the substrate, combined with whether the vibration detection sensor module collects vibration signals, it is determined whether the trainee has effectively hit the pickle ball on the substrate at that coordinate point. Subsequently, the trainee can determine which area still needs to be strengthened according to the coordinates. When it is determined that the trainee has effectively hit the pickle ball on the substrate based on the collected vibration signal, the effective count initial table records the number of effective hits, which is a gradually accumulated number.

[0055] Pressure sensing module: Based on the effective counting preliminary table, the ultra-thin pressure detection sensor module collects the impact signal and impact pressure of the pickle ball in the corresponding period to generate a count and pressure feedback table. When the effective counting preliminary table changes, the ultra-thin pressure detection sensor module collects the impact signal, and evaluates the authenticity of the effective number of impacts counted in the effective counting preliminary table based on the combination of the impact signal and the vibration signal. The ultra-thin pressure detection sensor module also collects the impact pressure of the pickle ball in the corresponding period to generate a count and pressure feedback table.

[0056] Visualization module: Based on the counting and pressure feedback table, the electrical signal is transmitted through the communication circuit to record and display the effective number of hits and pressure values ​​of pickleball training, and generate a training statistical report.

[0057] The vibration detection touch sensor module includes a first striking layer, a vibration sensor circuit layout layer, a fixed board layer, and a first connecting fixed column. The ultra-thin pressure detection sensor module includes a second striking layer, a buffer layer, a sensing layer, a circuit board layer, and a second connecting fixed column.

[0058] Both the first and second striking layers are made of electronic-grade FR4 glass fiber circuit board with a thickness of 1.6 mm. It has the characteristics of lightweight, high resilience and impact resistance. At the same time, the good temperature coefficient characteristics ensure that the designed sensor module still maintains a fixed size and thickness under temperature changes to ensure service life. The buffer layer uses a high-performance flexible silicone gasket with a thickness of 1 mm. Its main function is to give the striking layer an elastic buffering effect, transfer the force of the striking layer to the sensor sensing layer, and protect the accuracy of the sensor module sensing layer to the greatest extent. The sensing layer uses a flexible film pressure sensor with a thickness of 0.25 mm. Its main function is to convert the pressure signal into an electrical signal and supply it to the microprocessor CPU for calculation. It has an excellent "pressure-resistance" change linear relationship and ultra-thin size. It is the most important component of this sensor module. The circuit board layer also uses electronic The grade FR4 glass fiber circuit board has a thickness of 1.6 mm and is the signal data acquisition, calculation and communication processing unit of the sensor module. The microprocessor converts the pressure value of the pressure sensor into an electrical signal through an internal intelligent algorithm, and transmits it to the "control-display instrument panel" through the communication circuit. The first and second connecting and fixing columns are both made of stable brass columns, a total of three, evenly distributed on the circumferential edge of the striking layer, and the striking layer is firmly locked by welding. Its distribution composition layout is obtained through repeated laboratory experiments and can meet the elastic deformation requirements of the striking layer design of this sensor module, thereby ensuring that after the flying pickle ball hits the striking layer, it can achieve force transmission and maintain good rebound kinetic energy. The vibration sensor circuit layout layer is used to convert the vibration and impact of the pickle ball into the number of strikes through piezoelectric changes. The fixed board layer is FR4 glass fiber circuit board.

[0059] Working principle: When in use, the servo motor 202 drives the transmission rod 203 to rotate, so that the incomplete gear 1 204 and the incomplete gear 2 208 can rotate synchronously. When the incomplete gear 1 204 rotates, the convex teeth in the local area of ​​its surface can engage with the tooth plate 205 to drive the tooth plate 205 to move up and down along the limit rod 1 207, so that the L-shaped plate 206 can drive the base plate 5 to move synchronously along the H-shaped movable frame 4. At the same time, the incomplete gear 208 can intermittently drive the transmission gear 209 and the convex rod 210 at the eccentric part of its surface to rotate, and then, with the cooperation of the L-shaped bracket 1, when the rotating plate 211 is driven by the convex rod 210 to swing, a thrust can be applied to the convex rod 210 in the reverse direction, thereby The vertical plate 212 can make the driving bin 201 and the horizontal plate 213 at the bottom thereof receive the force exerted by the rotating plate 211. At this time, the H-shaped movable frame 4 connected to the horizontal plate 213 can drive the base plate 5 to move back and forth in the horizontal direction along the slideways reserved on both sides of the bottom of the L-shaped bracket 1. In summary, the coordinate position of the base plate 5 in space can be changed in real time, so that the trainer can hit the pickle ball to the base plate 5 at different positions to improve the authenticity of the simulated combat training and prevent the trainer from getting used to hitting the pickle ball within a fixed range. At the same time, the rotation of the incomplete gear 208 can use centrifugal force to drive the evenly distributed arc plates 2 303 away from the transmission rod 203, so that multiple arc plates 2 303 can be simultaneously moved. The arc plate 302 contacts and pushes the lower pressure frame 301 through the arc plate 302 to drive the concave plate 304 to move downward. As the pressure between the bottom surface of the concave plate 304 and the ground increases, the friction between it and the ground can be further enhanced with the cooperation of the texture on the bottom surface of the concave plate 304, so as to prevent the base plate 5 from driving the L-shaped bracket 1 to move or deflect through the H-shaped movable frame 4 when the pickle ball hits the base plate 5, and further prevent the deflection of the base plate 5, the H-shaped movable frame 4, etc. from affecting the normal training of the trainee. In addition, during the training process, the coordinate position of the base plate 5 can be recorded through the base plate motion module, and the moving speed of the base plate 5 can be adjusted according to the training level of the trainee, so as to prevent the base plate 5 from moving too fast and causing the trainee to continuously The pickle ball cannot be hit back to the substrate 5 for many times, thereby avoiding the inability to effectively collect training data. At the same time, the strike counting module can collect vibration data when the pickle ball collides with the substrate 5, and then preliminarily determine whether the pickle ball hits the substrate 5, and further determine the trainee's counterattack ability in different coordinate areas, so as to facilitate subsequent targeted training. In addition, the pressure sensing module can verify the result of the strike counting module detection through the collision pressure, and count the pressure, so as to understand the physical consumption of the trainee, and after long-term statistics, the degree of physical training can be grasped, and the visualization module can directly reflect the physical training results of the current time period with numbers, so that the trainee can truly understand his actual situation.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
