[0005] A baseball hitting trainer comprises a base, a middle section and a ball drag. The middle section comprises an outer tube and a battery pack, a circuit board, a guide sleeve and an optical fiber bundle which are sequentially arranged in the outer tube from bottom to top. A lamp is connected to the circuit board. A convex ring is arranged at one end of the optical fiber bundle. A conductive sleeve is relatively fixed to the outer periphery of the convex ring at this end. A limit sleeve is arranged on the upper sleeve of the optical fiber bundle. The conductive sleeve is threadedly connected to the limit sleeve. An elastic member which is sleeved on the outer periphery of the conductive sleeve is arranged between the guide sleeve and the limit sleeve. The conductive sleeve is arranged in the guide sleeve and can slide up and down along the guide sleeve. When the conductive sleeve moves downward, a trigger switch is triggered to cause the lamp arranged on the circuit board to light up instantly, and the color of the light is random. The trainer can recognize the light emitted by the lamp only when he stares at the ball flying out instantly with full concentration. The other end of the optical fiber bundle extends out of the port of the ball drag. A baseball is placed on the ball drag. The conductive sleeve is driven downward by the gravity of the baseball by the optical fiber bundle.

[0006] There are multiple parallel optical fiber bundles, one end of which is fixed together by gluing in the outer tube, a convex ring is injection molded on the periphery of the gluing end, a convex edge is provided on the upper end of the limiting sleeve, and one end of the elastic member abuts against the convex edge.

The middle section 2 comprises an outer tube 3 and a battery pack 31, a circuit board 32, a guide sleeve 4 and an optical fiber bundle 33 which are sequentially placed in the outer tube 3 from bottom to top. A lamp 5 is connected to the circuit board 32. A convex ring 331 is provided at one end of the optical fiber bundle 33, and a conductive sleeve 332 is relatively fixed to the outer periphery of the convex ring 331 at this end. A limiting sleeve 333 is sleeved on the optical fiber bundle 33, and the conductive sleeve 332 is threadedly connected to the limiting sleeve 333. A conductive sleeve 332 is sleeved between the guide sleeve 4 and the limiting sleeve 333. The conductive sleeve 332 is placed in the guide sleeve 4 and can slide up and down along the guide sleeve 4. When the conductive sleeve 332 moves downward, it touches the trigger switch, causing the light 5 set on the circuit board 32 to light up instantly, and the light color is random. The practitioner can only recognize the light emitted by the light 5 when he concentrates on staring at the ball flying out instantly. The other end of the optical fiber bundle 33 extends out of the port of the ball trailer 9. A baseball is placed on the ball trailer 9. The optical fiber bundle 33 drives the conductive sleeve 332 to move downward under the gravity of the baseball.

[0034] There are multiple parallel optical fiber bundles 33 , one end of which is located in the outer tube 3 and fixed together by gluing. A convex ring 331 is injection molded on the periphery of the gluing end. A convex edge 334 is provided on the upper end of the limiting sleeve 333 , and one end of the elastic member 6 abuts against the convex edge 334 .

[0035] The inner wall of the guide sleeve 4 is provided with two strip grooves 41, the bottom wall is provided with two through holes 42 and a central hole 43, one end of the strip groove 41 is provided with a stopper 411, and the other end extends to the through hole 42 and communicates with it, the strip groove 41 is provided with an elastic conductive sheet 7, the elastic conductive sheet 7 is provided with a protruding section 71 and an inclined section 72, one end of the elastic conductive sheet 7 is limited by the stopper 411, and the other end is inserted into the through hole 42, and the protruding section 71 extends into the guide sleeve 4. Figure 6 As shown, under the gravity of the baseball, the optical fiber bundle 33 and the convex ring 331 drive the conductive sleeve 332 to move downward along the guide sleeve 4, and the conductive sleeve 332 contacts and pushes the elastic conductive sheet 7 toward the strip groove 41, so that the two elastic conductive sheets 7 are connected, and the two elastic conductive sheets 7 and the conductive sleeve 332 form a trigger switch. When the ball is hit, the trigger switch is disconnected.

[0036] The end of the elastic conductive sheet 7 extending to the through hole 42 is inserted through the through hole 42 and connected to the circuit board 32. A lamp 5 is arranged above the circuit board 32. The lamp 5 is located in the center hole 43. The lower surface of the circuit board 32 is provided with annular positive and negative electrodes 34 located in the center and around the center respectively; the guide sleeve 4 is provided with a positioning column 44, and the circuit board 32 is provided with a positioning hole 321 for the positioning column 44 to be inserted. The lamp 5 is a lamp group, which is composed of LED lamps of various colors. As shown in the attached figure Figure 6 As shown,

[0037] The battery pack 31 includes a battery box 311 and a battery rack 312. At least one battery body 30 is installed in the battery rack 312. The battery rack 312 is provided with an electrode 1 3121 and a limiting edge 3122. The battery box 311 is a columnar structure, and an electrode 2 3112 is provided at its end. The electrode 2 3112 is connected to the electrode 3110 on the battery box 311 through a conductor 3113; the diameter of the limiting edge 3122 is larger than the inner diameter of the battery box 311. Fig.13 As shown, the battery holder 312 is effectively prevented from being installed upside down in the battery box 311 .

[0038] Electrode 1 3121 and electrode 2 3112 are respectively in contact with the positive and negative electrodes 34 on the circuit board 32. Both electrode 1 3121 and electrode 2 3112 are arranged in a telescopic structure. The telescopic structure includes a top contact 01, a fixed section 02 and a conductive elastic member 03. Fig.12 As shown, one end of the top contact 01 is placed in the groove of the fixed section 02, and a conductive elastic member 03 is provided between the two. The fixed section 02 is also made of conductive material and is fixed on the battery box 311 and the battery rack 312. This structure plays a buffering role when the two electrodes collide with the positive and negative electrodes 34 on the circuit board respectively, avoiding damage and ensuring contact, that is, conduction.

[0039] The base 1 includes a bottom plate 11, a base body 12 and a cylinder 13 located in the base body 12. A guide rod 14 is provided in the cylinder 13. One end of the guide rod 14 is connected and screwed to the cover body 35 at the end of the outer cylinder 3, and the other end is provided with a felt 141. The felt 141 generates friction with the inner wall of the cylinder 13.

[0040] The outer wall of the cylinder 13 is provided with at least two annular grooves 131, and rubber rings 132 are respectively provided in the two annular grooves 131. A cover plate 134 is provided on the base body 12. The cylinder 13 passes through the cover plate 134, and the rubber ring 132 located above plays a limiting role relative to the cover plate 134 to prevent the cylinder 13 from being pulled out; screws pass through the cover plate 134 and the base body 12 in turn and are screwed and fixed on the bottom plate 11.

[0041] A plug body 8 is provided at the upper end of the cylinder 13, and the guide rod 14 passes through the plug body 8. The inner wall of the cylinder 13 is provided with an annular groove 82 and an inner groove 81 for accommodating the plug body 8. The annular groove 82 is located above the plug body 8, and a C-shaped clamping ring 83 is provided in the annular groove 82.

[0042] The circuit on the circuit board 32 is connected to a processor. When the conductive sleeve 332 is downward, the two elastic conductive sheets 7 are turned on, that is, in a short-circuit state. When the baseball is hit, the optical fiber bundle 33 and the conductive sleeve 332 are reset by the force of the elastic member 6, that is, the two elastic conductive sheets 7 are disconnected, and the corresponding pin level changes from a low level to a high level, and the processor controls the corresponding LED lamp to emit light of random colors.

[0043] As attached Figure 14-17 As shown, the light control description is as follows: the processor is in low power mode after power-on to save power. When LS2 is short-circuited, the corresponding pin level changes from high level to low level. After the processor detects the level change, it wakes up from low power mode and enters working mode. Start timer 1 and start timing. When LS2 is disconnected, the corresponding pin level changes from low level to high level. After the processor detects the level change, it stops timer 1. Then compare the time value of timer 1 with the threshold value T1.

[0044] If it is higher than this value, it is considered as a long press, and the RGB LED light is controlled to emit random colors of light accordingly, and timer 2 is started. When timer 2 reaches the preset LED lighting time, the LED light is turned off and timer 2 is stopped.

[0045] If it is lower than this value, it is considered a short press, and the corresponding short press counter is incremented by one. If a long press occurs during a short press, the short press timer is cleared to 0. After 10 consecutive short presses, the configuration mode is entered, and the LED lighting time can be configured by repeatedly connecting LS2. The LED lighting time is cycled between 0.05 seconds and 1 second. In the configuration mode, if LS2 is not operated for 5 seconds, the configuration mode will be exited and the current LED lighting time will be stored in the processor.

[0046] In operating mode, if the LS2 is not operated for 15 seconds, the device will enter low power mode again to save power.

[0047] The baseball hitting trainer of the present invention has a reasonable and simple structural design, and is provided with a trigger switch and a battery pack. When the trigger switch is closed and then disconnected, the processor causes the light to light up with a random color and turn it off instantly. If the trainee can accurately report the light color, it is sufficient to show that the trainee is relatively focused.

[0048] Technical personnel should note that although the present invention has been described according to the above specific implementation methods, the inventive concept of the present invention is not limited to this invention, and any modification using the inventive concept will be included in the scope of protection of this patent.
