[0025] A taekwondo speed measurement standing foot target includes a mounting bracket 100, and a lifting assembly is arranged on the mounting bracket 100;

[0026] Lifting frame 200, a lifting frame 200 is provided on the front side of the mounting frame 100. The lifting frame 200 adjusts its own height through a lifting component. A horizontal chute 210 is opened at the top of the lifting frame 200. A horizontal slide bar 220 is fixedly arranged between the left and right side walls of the chute 210 of the chute 210. A slider 230 is slidably arranged on the rod body of the slide bar 220. A target body 240 is arranged below the bottom of the slider 230 and below the lifting frame 200. A buffer spring 250 parallel to the slide bar 220 is arranged between the outer side wall of the slider 230 and the inner side wall of the chute 210. A reflector 260 is arranged above the top of the slider 230 and above the lifting frame 200. An infrared distance measuring sensor 270 aligned with the reflector 260 is arranged at the top of the lifting frame 200.

[0027] Further, at least two mounting frames 100 are provided, and a vertical mounting groove 110 is opened on each mounting frame 100. The lifting component includes a lifting block 130 with a gap located in the inner cavity of the mounting groove 110. All the lifting blocks 130 are at the same height and their front surfaces are fixed on the rear side wall of the lifting frame 200. A vertical screw rod 120 is rotatably arranged on the bottom wall of the inner cavity of each mounting groove 110. The rod body of the screw rod 120 is screwed through the lifting block 130. When all the screw rods 120 rotate, all the lifting blocks 130 are driven to lift, so as to realize the adjustment of the overall height of the lifting frame 200, indirectly adjust the height of the target body 240, and thus meet the use requirements of trainers with different heights.

[0028] Further, the lifting component further includes a worm gear 140 arranged at the lower end of the rod body of each screw rod 120. A side plate 150 is arranged on the rear side wall of the mounting frame 100 behind the worm gear 140. A horizontal driving rod 160 is rotatably penetrated through the side wall of the side plate 150. A worm 170 meshing with the worm gear 140 is arranged on the rod body of the driving rod 160. When the driving rod 160 rotates, all the screw rods 120 are driven to rotate through the worm 170 and the worm gear 140.

[0029] Further, a hand crank 180 is arranged at one end of the driving rod 160, and the hand crank 180 is provided with anti-slip, which is convenient to drive the driving rod 160 to rotate through the hand crank 180.

[0030] Further, a base 190 is arranged at the bottom of each mounting frame 100. The base 190 is evenly provided with mounting holes in a surrounding manner. Screws or bolts adapted to the mounting holes are selected to install and fix the device, which is convenient for training.

[0031] Further, a smart screen 280 and a switch 290 are provided on the side wall of one of the mounting brackets 100. The switch 290 is electrically connected to the infrared ranging sensor 270. It should be noted that a control box is also provided on one mounting bracket 100. A processor and a power supply are provided inside the control box. The processor is electrically connected to the infrared ranging sensor 270, the smart screen 280, and the storage battery. When the switch 290 turns on the infrared ranging sensor 270, the infrared ranging sensor 270 emits a beam of infrared light. After irradiating the reflector 260, a reflection process is formed. After being reflected to the infrared ranging sensor 270, the signal is received. Then, the time difference data of the emission and reception is received and processed by CCD image processing. After being processed by the processor, the distance of the object is calculated, and the result is fed back and displayed on the smart screen 280. The smart screen 280 can adopt a display screen with a screen recording and playback function, which is convenient for viewing afterwards.

[0032] In the specific use process, the coach drives the driving rod 160 through the hand rocker 180 according to the height of the trainee, and then drives all the screw rods 120 to rotate through the worm 170 and the worm wheel 140, so that all the lifting blocks 130 are lifted and lowered, thereby realizing the adjustment of the overall height of the lifting frame 200 and indirectly adjusting the height of the target 240. After turning on the infrared ranging sensor 270 through the switch 290, the infrared ranging sensor 270 emits a beam of infrared light. After irradiating the reflector 260, a reflection process is formed. After being reflected to the infrared ranging sensor 270, the signal is received. After being processed by the processor, the distance of the object is calculated, and the result is fed back and displayed on the smart screen 280. The trainee stands within a specified distance area from the target 240. Moreover, the distance between the body part hitting the target 240 and the target 240 is measured to obtain the distance. The coach commands the trainee beside with a stopwatch. When the coach says to start, the stopwatch is started. The trainee immediately hits the target 240. When the value displayed on the smart screen 280 changes, it means that the trainee has touched the target 240. The coach pauses the stopwatch to get the time. Since the speed of movement can be measured by the distance passed within a unit time, knowing the distance and time, through calculation, the approximate range of the hitting speed of this trainee can be understood.

[0033] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way.
