Description
Technical Field
[0001] This invention relates to the field of sports training equipment technology, and in particular to an intelligent roller skating training machine with a timer reminder function. Background Technology
[0002] Roller skating is a skill-based sport with artistic performance elements, making it very popular among young people. However, high-difficulty continuous spins on one or both feet, as well as 360, 720, and 1080-degree jumps, are much more difficult than performing on ice skates. This is because when performing spins on ice skates, the friction between the underside of the skate blade and the ice surface is very small. By maintaining a standing posture while spinning, continuous spins can be achieved by using inertia when the axis of rotation coincides with the center of gravity.
[0003] For beginners in roller skating, the range and displacement of swaying from side to side are difficult to control, resulting in more falls. They also struggle to control the swinging motion to the desired degree, often failing to maintain balance and causing their bodies to lag behind their brain's commands. Furthermore, beginners often misjudge training time, leading to excessive injuries. Existing timing devices are mostly timers, providing only audible and visual warnings, but failing to directly convey the timer reminders to the trainees, resulting in ineffective reminders. Summary of the Invention
[0004] In view of this, the present invention provides an intelligent roller skating training machine with a timed reminder function to solve the problem that the body cannot keep up with the brain's command due to the inability to fully master body balance, and beginners are prone to over-injury due to poor control of the training time. Existing timed devices are mostly timers, which only have sound and visual warning effects, and it is difficult to directly convey the timed reminder effect to the trainees, resulting in poor reminder effect.
[0005] This invention provides an intelligent roller skating training machine with a timed reminder function, specifically including: a treadmill frame; a gantry-shaped support frame fixedly installed on the upper end of the treadmill frame, with the bottom support frames of the support frame located on the left and right sides of the treadmill frame; a protective frame fixedly installed above the middle rear of the base frame of the support frame; a vertically sliding handrail frame horizontally installed on the vertical frame of the support frame; a handrail seat horizontally slidably installed on the handrail frame, the upper end of the handrail seat being fixedly connected to the lower end of the piston rod of a lifting electric cylinder, the upper end of the lifting electric cylinder being horizontally slidably engaged with the top frame of the support frame; a control box fixedly installed on the front of the left side wall of the protective frame; and a timer disc rotatably installed on the back of the housing of the lifting electric cylinder.
[0006] Optionally, the running front end of the treadmill frame is an arc-shaped shock-absorbing protective shell at the top, and the upper surface of the shock-absorbing protective shell is covered with an anti-collision rubber layer.
[0007] Optionally, the left and right ends of the support frame are vertically upright poles located at the front center. The four vertical sides of the upright poles are rounded. A rectangular top horizontal plate is fixedly connected between the upper ends of the two upright poles. A vertically extending movable stroke hole is opened in the middle of the top horizontal plate, through which the upper end of the lifting electric cylinder passes.
[0008] Optionally, a row of vertical guardrail shafts is fixedly installed vertically downwards at the bottom of both ends of the protective frame. The lower end of the guardrail shafts is vertically fixedly connected to the supporting guardrail. Anti-collision rubber buckets are rotatably installed on the guardrail shafts. The anti-collision rubber buckets have a spindle-shaped structure that is narrow at both ends and wide in the middle. The middle of the front and rear crossbars at the top of the protective frame are both cylindrical tie rods, and safety belt pull ropes are sleeved on the tie rods. Warning lights are symmetrically fixedly installed on the bottom surface of the front end of the top of the protective frame. By default, the warning lights are green.
[0009] Optionally, the left and right ends of the handrail are respectively vertically slidably connected to the uprights. The front end of the handrail is a horizontal guide rod, and the rear end of the handrail is a lead screw. The left and right ends of the lead screw are respectively rotatably mounted on the sleeves at the rear ends of the left and right ends of the handrail. A DC brushless motor is fixedly installed at the left end of the handrail. The shaft of the DC brushless motor is fixedly connected to the lead screw through a coupling. The front end of the handrail seat is horizontally and vertically slidably connected to the guide rod, and the rear end of the handrail seat is rotatably screwed to the lead screw.
[0010] Optionally, handles are fixedly installed at both ends of the armrest, and a lead screw passes through the handles via a screw thread. Two horizontal movement buttons are symmetrically fixedly installed on the back surface of the armrest, and a T-shaped anti-accidental touch cover is fixedly installed vertically backward on the armrest between the two horizontal movement buttons. The anti-accidental touch cover protects the two horizontal movement buttons backward. The two horizontal movement buttons are respectively connected to the forward and reverse circuits of the DC brushless motor, and the horizontal movement buttons are press-to-connect switches. A vertical movement toggle switch is fixedly installed at the rear of the left side wall of the armrest. The vertical movement toggle switch is electrically connected to the lifting electric cylinder. When the vertical movement toggle switch is turned up, the piston rod of the lifting electric cylinder retracts; when the vertical movement toggle switch is turned down, the piston rod of the lifting electric cylinder extends.
[0011] Optionally, four clamping guide rollers are vertically fixedly installed on the upper ends of the front and rear side walls of the lifting electric cylinder, with two clamping guide rollers located at the upper end of the top horizontal plate and two clamping guide rollers located at the lower end of the top horizontal plate; a rotating shaft is vertically provided on the lower back of the lifting electric cylinder housing, and the timing disc is rotatably hung on the rotating shaft; a limiting magnetic groove is opened in the lifting electric cylinder housing directly above the rotating shaft, and the groove wall of the limiting magnetic groove is a magnet with positive magnetic pole.
[0012] Optionally, two timing fixing frames are symmetrically fixedly installed on the back side wall of the timing disk. One end of each timing fixing frame is open. A reset trigger switch is built into the middle of the inner side wall of the timing fixing frame away from the open end. The reset trigger switch is electrically connected to the controller in the control box. Orientation buffer rods are vertically fixedly installed at the left and right ends of the inner cavity of each timing fixing frame. A buffer spring is fitted onto each orientation buffer rod, and a concave locking block is fixedly connected to the end of the buffer spring. The locking block slides vertically onto the orientation buffer rod, and a T-shaped quicksand storage bottle is fitted between the two locking blocks. The upper and lower quicksand storage bottles are connected by a... The quicksand connecting pipe is a spiral flexible tube. The quicksand storage bottle stores quicksand. When quicksand is stored in a single quicksand storage bottle, the quicksand storage bottle can drive the locking block to compress the buffer spring. The inner end of the quicksand storage bottle will press against the reset trigger switch. The DC brushless motor and the lifting electric cylinder will both reset to the initial center position, and the warning light will change from green to red. Limiting holes are opened at the upper and lower ends of the timer disk near the edge. A limiting magnetic rod is vertically inserted into the limiting hole at the upper end. The inner end of the limiting magnetic rod passes through the limiting hole and is inserted into the limiting magnetic groove. The polarity of the limiting magnetic rod and the wall of the limiting magnetic groove are opposite.
[0013] The beneficial effects are:
[0014] 1. When the present invention performs timing, the single sand storage bottle containing all the quicksand is positioned at the top, and the limiting magnetic rod is inserted into the limiting socket at the top. The quicksand in the storage bottle enters the storage bottle below through the quicksand connecting pipe until the storage bottle below has received all the quicksand. This period is the timing period. At this time, the reset trigger switch is triggered, the DC brushless motor and the lifting electric cylinder perform a reset action, and the running belt stops running, forcing the trainee to receive a clear reset action reminder, thereby achieving the effect of intelligent timing reminder. It not only provides time reminders but also specific action reminders, thereby improving the execution effect of timing reminders.
[0015] 2. This invention allows trainees to practice by gripping the handles, facilitating the simulation of left and right movements during roller skating. The support provided by the handles prevents beginners from falling and losing control during left and right skating. The horizontal movement button is located at the thumb position, making it easier to control the left and right movement of the handles. The presence of an anti-accidental touch cover prevents accidental activation, allowing for free left and right movement. Releasing the horizontal movement button stops the movement. The vertical movement switch allows for vertical displacement via a suspended electric cylinder, adjusting the trainee's bending degree during roller skating training to help them find the optimal bending position and improve the standardization of training movements.

[0029] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.
[0030] Example 1: Please refer to Figures 1 to 8 As shown:
[0031] This invention provides an intelligent roller skating training machine with a timed reminder function, including a treadmill frame 1; a gantry-shaped support frame 2 is fixedly installed on the upper end of the treadmill frame 1, and the bottom support frames of the support frame 2 are respectively placed on the left and right sides of the treadmill frame 1; a protective frame 3 is fixedly installed on the upper part of the middle rear of the base frame of the support frame 2; a vertically sliding handrail frame 4 is horizontally installed on the vertical frame of the support frame 2; a handrail seat 5 is horizontally slidably installed on the handrail frame 4, the upper end of the handrail seat 5 is fixedly connected to the lower end of the piston rod of the lifting electric cylinder 6, and the upper end of the lifting electric cylinder 6 is horizontally slidably engaged with the top frame of the support frame 2; a control box 7 is fixedly installed on the front part of the left side wall of the protective frame 3; a timer disc 8 is rotatably installed on the back of the housing of the lifting electric cylinder 6.
[0032] Among them, the running front end of the treadmill frame 1 is an arc-shaped shock-absorbing protective shell 101 at the top. The upper surface of the shock-absorbing protective shell 101 is covered with an anti-collision rubber layer, which can prevent the machine from sliding forward during training and reduce the risk of forward tilting injury to the trainee.
[0033] Among them, the left and right ends of the support frame 2 are vertically upright poles 201 with rounded corners on all four sides of the upright poles 201 to ensure the smooth vertical movement of the handrail seat 5. A rectangular top horizontal plate 202 is fixedly connected between the upper ends of the left and right upright poles 201. The top horizontal plate 202 has a horizontal through-hole 203 in the middle. The upper end of the lifting electric cylinder 6 passes through the through-hole 203, which provides movement space for the lifting electric cylinder 6.
[0034] Among them, a row of vertical guardrail rods 301 are fixedly installed vertically downward at the bottom of the left and right ends of the protective frame 3. The lower end of the guardrail rods 301 is vertically fixedly connected to the support frame 2. Anti-collision rubber buckets 302 are rotatably installed on the guardrail rods 301. The anti-collision rubber buckets 302 have a spindle-shaped structure that is narrow at both ends and wide in the middle. The spindle-shaped anti-collision rubber buckets 302 can reduce the injury to trainees from falling during training.
[0035] The upper end of the protective frame 3 has two horizontal bars at the front and rear, each with a cylindrical central tie rod 303 in the middle. A safety belt pull rope 304 is sleeved on the central tie rod 303. The pull rope 304 can be used in conjunction with the safety belt to improve the safety protection of trainees.
[0036] Warning lights 305 are symmetrically fixed on the top front bottom surface of the protective frame 3. By default, the warning lights 305 are green to warn trainees of the training time.
[0037] The handrail frame 4 has its left and right ends vertically slidably connected to the upright 201. The front end of the handrail frame 4 is a horizontal guide rod 401, and the rear end of the handrail frame 4 is a lead screw 402. The left and right ends of the lead screw 402 are rotatably mounted on the sleeves at the rear ends of the left and right ends of the handrail frame 4. A DC brushless motor 403 is fixedly installed on the left end of the handrail frame 4. The shaft of the DC brushless motor 403 is fixedly connected to the lead screw 402 through a coupling. The front end of the handrail seat 5 is horizontally and vertically slidably connected to the guide rod 401, and the rear end of the handrail seat 5 is rotatably screwed to the lead screw 402. When the DC brushless motor 403 rotates, it can drive the lead screw 402 to rotate. When the lead screw 402 rotates, it can drive the handrail seat 5 to move left and right. During the left and right movement, the guide rod 401 can ensure that the handrail seat 5 remains horizontal. The DC brushless motor 403 can drive the handrail seat 5 to move left or right by rotating forward and reverse.
[0038] The armrest seat 5 has handles 501 fixedly installed at both ends, with a lead screw 402 threaded through the handles 501. Two horizontal movement buttons 502 are symmetrically fixedly installed on the back of the armrest seat 5. A T-shaped anti-accidental-touch cover 503 is vertically fixedly installed on the armrest seat 5 between the two horizontal movement buttons 502, protecting the two buttons 502 from the rear. The two buttons 502 are connected to the forward and reverse circuits of the DC brushless motor 403, respectively, and are push-to-operate switches. A vertical movement toggle switch 504 is fixedly installed on the rear side wall of the left end of the armrest seat 5. The vertical movement toggle switch 504 is electrically connected to the lifting electric cylinder 6. When the vertical movement toggle switch 504 is turned up, the piston rod of the lifting electric cylinder 6 retracts, and the vertical movement toggle switch 504... When the lever is pulled down, the piston rod of the electric cylinder 6 extends, allowing trainees to grip the handle 501 for training. This assists in simulating left and right movements during roller skating. The support provided by the handrail seat 5 prevents beginners from falling or losing control during left and right skating. The horizontal movement button 502 is located at the thumb position, making it easier to control the left and right movement of the handrail seat 5. The presence of the anti-accidental touch cover 503 prevents accidental touches, allowing for free left and right movement. Releasing the horizontal movement button 502 stops the movement. The vertical movement switch 504 allows the electric cylinder 6 to be pulled vertically, adjusting the trainee's bending degree during roller skating training to find the optimal bending position and improve the standardization of training movements.
[0039] Example 2:
[0040] This invention provides an intelligent roller skating training machine with a timed reminder function. It further includes four clamping guide rollers 601 vertically fixed to the upper ends of the front and rear side walls of a lifting electric cylinder 6, with two clamping guide rollers 601 located above a top horizontal plate 202 and two clamping guide rollers 601 located below the top horizontal plate 202. A rotating shaft 602 is vertically provided on the lower back of the housing of the lifting electric cylinder 6, and a timer disc 8 is rotatably suspended on the rotating shaft 602. A limiting magnetic groove 603 is formed in the housing of the lifting electric cylinder 6 directly above the rotating shaft 602. The groove wall of the limiting magnetic groove 603 is a positively charged magnet. Two timer fixing frames 801 are symmetrically fixed to the back side wall of the timer disc 8. One end is open. A reset trigger switch 809 is built into the inner wall of the timing frame 801, away from the open end. The reset trigger switch 809 is electrically connected to the controller in the control box 7. Orientation buffer rods 806 are vertically fixedly installed at both ends of the inner cavity of the timing frame 801. A buffer spring 807 is fitted onto the orientation buffer rod 806. A concave locking block 808 is fixedly connected to the end of the buffer spring 807. The locking block 808 slides vertically onto the orientation buffer rod 806. A T-shaped quicksand storage bottle 802 is fitted between the two locking blocks 808. The two quicksand storage bottles 802 are connected by a quicksand connecting pipe 805, which is a spiral flexible tube. The storage bottle 802 stores quicksand. When quicksand is stored in a single quicksand storage bottle 802, the quicksand storage bottle 802 can drive the locking block 808, causing the buffer spring 807 to compress. The inner end of the quicksand storage bottle 802 will be pressed against the reset trigger switch 809, and the DC brushless motor 403 and the lifting electric cylinder 6 will both reset to the initial center position, and the warning light 305 will change from green to red. Limiting holes 804 are respectively opened at the upper and lower ends near the edges of the timing disk 8. A limiting magnetic rod 803 is vertically inserted into the upper limiting hole 804. The inner end of the limiting magnetic rod 803 passes through the limiting hole 804 and is inserted into the limiting magnetic groove 603. The polarity of the limiting magnetic rod 803 and the groove wall of the limiting magnetic groove 603 are opposite. When in use... First, a timer is set so that the single sand storage bottle 802 containing all the quicksand is at the top, and the limiting magnetic rod 803 is inserted into the limiting socket 804 at the top. The quicksand in the storage bottle 802 flows through the quicksand connecting pipe 805 into the storage bottle 802 at the bottom, until the storage bottle 802 at the bottom has received all the quicksand. This period is the timer period. At this time, the reset trigger switch 809 is triggered, and the DC brushless motor 403 and the lifting electric cylinder 6 perform a reset action, and the running belt stops running. This forces the trainee to receive a clear reset action reminder, thereby achieving the effect of intelligent timer reminder. It not only provides time reminders but also specific action reminders, thus improving the execution effect of the timer reminder.
[0041] The specific usage and function of this embodiment: When using this invention, the trainee enters the running belt of the treadmill frame 1 from the rear side of the device, puts on the safety belt, and is pulled by the safety belt pull rope 304. The trainee holds the handle 501 and turns on the running belt of the treadmill frame 1. Since a vertical movement switch 504 is fixedly installed on the rear side wall of the left end of the handrail seat 5, the vertical movement switch 504 is electrically connected to the lifting electric cylinder 6. When the vertical movement switch 504 is turned up, the piston rod of the lifting electric cylinder 6 retracts; when the vertical movement switch 504 is turned down, the piston rod of the lifting electric cylinder 6 extends. The trainee can train by holding the handle 501 to assist in simulating left and right movement during roller skating. The support force provided by the handrail seat 5 can prevent beginners from falling and losing control during left and right sliding. The horizontal movement button 502 is located at the position of the thumbs, which makes it easier to control the left and right movement of the handrail seat 5. Moreover, due to the anti-accidental touch shielding... The presence of plate 503 prevents accidental contact. The left and right ends of the handrail frame 4 are vertically slidably connected to the upright 201. The front end of the handrail frame 4 is a horizontal guide rod 401, and the rear end is a lead screw 402. The left and right ends of the lead screw 402 are rotatably mounted on the sleeves at the rear ends of the left and right ends of the handrail frame 4. A DC brushless motor 403 is fixedly installed on the left end of the handrail frame 4. The shaft of the DC brushless motor 403 is fixedly connected to the lead screw 402 via a coupling. The front end of the seat 5 is slidably connected to the guide rod 401 in a horizontal and vertical manner, and the rear end of the armrest seat 5 is rotatably screwed to the lead screw 402. When the DC brushless motor 403 rotates, it can drive the lead screw 402 to rotate. When the lead screw 402 rotates, it can drive the armrest seat 5 to move left and right. During the left and right movement, the guide rod 401 can ensure that the armrest seat 5 always remains horizontal. The DC brushless motor 403 can drive the armrest seat 5 to move left or right by rotating forward and reverse.
[0042] When timing is required, the timing disk 8 is rotatably hung on the rotating shaft 602, which is vertically mounted on the lower back of the housing of the hoisting electric cylinder 6. A limiting magnetic groove 603 is provided in the housing of the hoisting electric cylinder 6 directly above the rotating shaft 602. The groove wall of the limiting magnetic groove 603 is a positively charged magnet. Two timing fixing frames 801 are symmetrically fixed on the back side wall of the timing disk 8. The opposite end of the two timing fixing frames 801 is an open end. A reset trigger switch is built into the middle of the inner side wall of the timing fixing frame 801, away from the open end. 809, the reset trigger switch 809 is electrically connected to the controller inside the control box 7; directional buffer rods 806 are vertically fixedly installed at the left and right ends of the inner cavity of the timing fixing frame 801, and buffer springs 807 are fitted on the directional buffer rods 806. A concave locking block 808 is fixedly connected to the end of the buffer spring 807. The locking block 808 slides vertically onto the directional buffer rod 806, and a T-shaped quicksand storage bottle 802 is fitted between the two left and right locking blocks 808. The upper and lower quicksand storage bottles 802 are connected by a quicksand connecting pipe 805. 05 is a spiral hose. The quicksand storage bottle 802 stores quicksand. When quicksand is stored in a single quicksand storage bottle 802, the quicksand storage bottle 802 can drive the locking block 808, compressing the buffer spring 807. The inner end of the quicksand storage bottle 802 will press against the reset trigger switch 809, causing the DC brushless motor 403 and the lifting electric cylinder 6 to reset to their initial centered positions, and the warning light 305 changes from green to red. Limiting holes 804 are respectively opened at the upper and lower ends of the timer disk 8 near the edges. A limiting magnet is vertically inserted into the upper limiting hole 804. The inner end of the limiting magnetic rod 803 passes through the limiting insertion hole 804 and is inserted into the limiting magnetic groove 603. The limiting magnetic rod 803 and the groove wall of the limiting magnetic groove 603 have opposite polarities. When in use, timing is first performed so that the single sand storage bottle 802 containing all the sand is at the top, and the limiting magnetic rod 803 is inserted into the upper limiting insertion hole 804. The sand in the sand storage bottle 802 enters the lower sand storage bottle 802 through the sand connecting pipe 805 until the lower sand storage bottle 802 has received all the sand. This period of time is the timing period.
