Description

Technical Field

[0001] This invention relates to the field of ice hockey training technology, and in particular to an obstacle device for ice hockey training and its method of use. Background Technology

[0002] Ice hockey, also known as ice hockey, is a highly competitive team ice sport that deeply integrates agile and varied skating skills with precise and skillful hockey techniques. Players must wear ice skates and hold hockey sticks to complete a series of actions such as controlling the puck, passing, and shooting while skating at high speed. The pace of offense and defense is extremely fast, which tests not only individual reaction speed and technical proficiency, but also relies heavily on team tactical cooperation and tacit understanding.

[0003] In traditional ice hockey training, obstacle devices are mostly fixed, one-piece structures that can only provide a single training scenario and have extremely poor flexibility. Even if some are adjustable, it is necessary to manually insert, remove, and move the obstacle posts to change the formation. This not only requires additional manpower to assist throughout the process, but also takes a long time to adjust, and training must be paused during the adjustment process. The athletes' training rhythm is forcibly interrupted, making it difficult to maintain a continuous training state and feel. Therefore, it is necessary to propose an obstacle device for ice hockey training and its usage method. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing obstacle devices, which are mostly fixed, integrated structures that can only provide a single training scenario and have extremely poor flexibility. Even if some are adjustable, manual insertion, removal, and movement of obstacle posts are required to change the formation, which not only requires additional manpower for the entire process but also requires moving and positioning each obstacle individually during adjustment. Therefore, this invention proposes an obstacle device for ice hockey training and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An obstacle device for ice hockey training includes a lower base plate, two sets of support plates are fixedly connected to the upper side of the lower base plate, and an obstacle plate is fixedly connected to the upper side of both sets of support plates. The surface of the barrier plate has multiple sets of through holes, and each set of through holes is slidably connected to a barrier post. A circular abutment is fixedly connected to the bottom of the barrier post. An obstacle assembly is provided on the lower base plate. The obstacle assembly includes four sets of servo motors installed at the corners of the upper surface of the lower base plate. The output end of the servo motor is fixedly connected to a winding shaft. A traction rope is installed on the winding shaft. A limit tray is movably connected to the end of the traction rope away from the winding shaft. A vertical column is fixedly connected inside the limit tray.

[0006] The above technical solution further includes: Specifically, the four sets of servo motors are arranged in a ring array around the limiting tray at the upper corner of the bottom plate.

[0007] Specifically, the limiting tray has multiple sets of locking holes, which are evenly distributed around the circumference of the limiting tray. A U-shaped plate is engaged with the inner side of each locking hole, and the outer side of the U-shaped plate is fixedly connected to the traction rope.

[0008] Specifically, an amplification plate is fixedly connected to the lower part of the vertical column, and a caster wheel is hinged to the end of the amplification plate away from the vertical column. The caster wheel makes rolling contact with the upper surface of the lower base plate.

[0009] Specifically, a return spring is fixedly connected between the circular abutment plate and the barrier plate, and the return spring is sleeved on the outside of the barrier post.

[0010] Specifically, the top of the obstacle post is provided with an arc-shaped rubber buffer head, and the outer wall of the arc-shaped rubber buffer head is provided with anti-slip texture.

[0011] Specifically, the outer diameter of the barrier post is adapted to the inner diameter of the through hole.

[0012] Specifically, the traction rope is provided in four sets, and each of the four sets of traction ropes is connected to one of the four sets of servo motors.

[0013] Specifically, the traction rope is a wear-resistant nylon braided rope, and an anti-detachment buckle is provided at the connection between the traction rope and the winding shaft.

[0014] A method of using an obstacle device for ice hockey training, based on the aforementioned obstacle device, includes the following steps: S1. Start the four sets of servo motors, and the winding shaft winds up the traction rope; S2. The traction rope pulls the limiting tray to move, and the limiting tray drives the vertical column to move synchronously; S3. The vertical column presses against the circular abutment, and the circular abutment causes the obstacle column to slide along the through hole, forming an ice hockey training obstacle; S4. Turn off the servo motor, reset the obstacle post, and complete one round of training.

[0015] The present invention has the following beneficial effects: In this invention, four sets of servo motors are arranged in a circular array around the limiting tray and are connected one-to-one with the traction rope. The movement trajectory of the limiting tray and the vertical column can be controlled by synchronous or differentiated start and stop, which drives the obstacle column to move in the vertical direction. With the reset spring sleeved on the outside of the obstacle column, the obstacle column can be quickly pushed back to its original position after the servo motor unwinds the traction rope in the opposite direction. No manual adjustment is required, which greatly improves training efficiency. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] like Figures 1-9 As shown, the present invention proposes an obstacle device for ice hockey training, including a lower base plate 1, two sets of support plates 101 fixedly connected to the upper side of the lower base plate 1, and an obstacle plate 102 fixedly connected to the upper end of the two sets of support plates 101. The surface of the barrier plate 102 has multiple sets of through holes 103, and each set of through holes 103 is slidably connected to a barrier post 2. A circular abutment plate 201 is fixedly connected to the bottom of the barrier post 2. An obstacle assembly is provided on the lower base plate 1. The obstacle assembly includes four sets of servo motors 3 installed at the corners of the upper surface of the lower base plate 1. The output end of the servo motor 3 is fixedly connected to a winding shaft 301. A traction rope 4 is installed on the winding shaft 301. The end of the traction rope 4 away from the winding shaft 301 is movably connected to a limit tray 5. A vertical column 6 is fixedly connected inside the limit tray 5.

[0020] Furthermore, the lower base plate 1 serves as the basic support component of the entire device, providing a mounting carrier for all components on it. Two sets of support plates 101 provide stable support for the obstacle plate 102. Multiple sets of through holes 103 on the surface of the obstacle plate 102 provide a sliding trajectory for the obstacle post 2. The circular abutment plate 201 at the bottom of the obstacle post 2 is used to bear external forces. When training obstacles need to be formed, four sets of servo motors 3 at the corners of the upper end face of the lower base plate 1 are activated. The servo motors 3 output power to drive the winding shaft 301 to rotate. When the winding shaft 301 rotates, it winds up the traction rope 4 installed on it. During the winding process, the traction rope 4 will pull the limit tray 5 connected to it to move. The limit tray 5 moves synchronously with the vertical column 6 fixedly connected inside it. The moving vertical column 6 will squeeze the circular abutment plate 201, thereby driving the obstacle post 2 to slide upward along the through hole 103 and extend out of the surface of the obstacle plate 102 to form the obstacle required for ice hockey training. Conversely, controlling the servo motor 3 to rotate in the opposite direction will cause the winding shaft 301 to unwind the traction rope 4, which can reset the obstacle post 2. If it is necessary for the vertical column 6 to move on the upper part of the lower base plate 1, the four sets of servo motors 3 can be started in a differentiated manner, that is, the speed or direction of some servo motors 3 can be adjusted to produce a difference in traction force in different directions. The limit tray 5 will deflect due to uneven force, thereby driving the vertical column 6 to move on the upper part of the lower base plate 1.

[0021] Four sets of servo motors 3 are arranged in a ring array around the limit tray 5 at the upper corner of the bottom plate 1.

[0022] Furthermore, the lower base plate 1 serves as the basic mounting carrier for all components, providing a stable support plane for the four servo motors 3. The limiting tray 5 is the central reference for determining the distribution position of the servo motors 3. The four servo motors 3 are distributed in a circular array at the upper corner of the lower base plate 1 with this as the center. This symmetrical layout allows the four servo motors 3 to output power synchronously during operation. Through their respective connected winding shafts and traction ropes, they apply uniform pulling force to the limiting tray 5 from four directions.

[0023] The limiting tray 5 has multiple sets of locking holes 501, which are evenly distributed around the circumference of the limiting tray 5. A U-shaped plate 502 is engaged on the inner side of the locking hole 501, and the outer side of the U-shaped plate 502 is fixedly connected to the traction rope 4.

[0024] Furthermore, the limiting tray 5, as the core component for bearing and connection, has multiple sets of locking holes 501 evenly distributed around its circumference, providing multiple selectable snap-fit ​​positions for the U-shaped plate 502. During operation, the U-shaped plate 502 snaps into the inner side of the corresponding locking hole 501, achieving a stable connection with the limiting tray 5. At the same time, the outer side of the U-shaped plate 502 is fixedly connected to the traction rope 4. When the traction rope 4 is pulled by the servo motor, the force is transmitted to the limiting tray 5 through the U-shaped plate 502. The evenly distributed locking holes 501 around the circumference allow the traction force to act on the limiting tray 5 from multiple symmetrical directions, preventing it from shifting under force, thereby driving the limiting tray 5 to move smoothly.

[0025] An amplification plate 7 is fixedly connected to the lower part of the vertical column 6. A caster wheel 8 is hinged to the end of the amplification plate 7 away from the vertical column 6. The caster wheel 8 makes rolling contact with the upper surface of the lower base plate 1.

[0026] Furthermore, the vertical column 6, as the core component for power transmission, has an amplification plate 7 fixedly connected to its lower part, which serves to extend support and transmit force. When the vertical column 6 moves with the limiting tray, it will synchronously drive the amplification plate 7 to move. The universal wheel 8, which is hinged to the end of the amplification plate 7 away from the vertical column 6, can maintain rolling contact with the upper surface of the lower base plate 1. The hinge structure allows the universal wheel 8 to flexibly adjust the rolling angle to adapt to the movement trajectory of the vertical column 6. The rolling contact method can significantly reduce the frictional resistance between the amplification plate 7 and the lower base plate 1, thereby assisting the vertical column 6 to move more smoothly on the upper part of the lower base plate 1. At the same time, the amplification plate 7 can also enhance the structural stability of the vertical column 6 during the movement process, preventing it from tipping over or deviating.

[0027] A return spring 202 is fixedly connected between the circular support plate 201 and the barrier plate 102, and the return spring 202 is sleeved on the outside of the barrier post 2.

[0028] Furthermore, the circular support plate 201 is used to receive the squeezing force from the vertical column and transmit the force to the obstacle column 2. The obstacle plate 102 provides a fixed support point for the return spring 202. The return spring 202, which is fixedly connected between the two, is sleeved on the outside of the obstacle column 2. This ensures the coaxiality of the spring during extension and contraction, avoids skew and jamming, and also guides and assists the sliding of the obstacle column 2. During operation, when the circular support plate 201 is squeezed, it causes the obstacle column 2 to slide along the through hole. The return spring 202 is compressed and stores elastic potential energy. When the squeezing force disappears, the return spring 202 releases the elastic potential energy, pushes the circular support plate 201 to move in the opposite direction, and then drives the obstacle column 2 to automatically reset, so as to realize the rapid switching of ice hockey training obstacles.

[0029] The top of the obstacle post 2 is equipped with an arc-shaped rubber buffer head, and the outer wall of the arc-shaped rubber buffer head is provided with anti-slip texture.

[0030] Furthermore, the arc-shaped rubber buffer head at the top of obstacle post 2 utilizes the elasticity of the rubber material and the arc-shaped structural design to buffer the impact of the ice puck on obstacle post 2. This reduces the rebound force of the ice puck, prevents the ice puck from bouncing irregularly due to rigid collision, and also reduces the wear and tear on obstacle post 2 itself. The anti-slip texture on the outer wall of the arc-shaped rubber buffer head increases the friction when the ice puck contacts the buffer head, preventing excessive slippage after the impact and making the rebound trajectory of the ice puck more controllable, thereby improving the effectiveness and realism of ice hockey training.

[0031] The outer diameter of the barrier post 2 is matched with the inner diameter of the through hole 103.

[0032] Furthermore, the through hole 103 serves as a carrier providing a sliding path for the obstacle post 2. The outer diameter of the obstacle post 2 is matched with the inner diameter of the through hole 103, ensuring that the obstacle post 2 will not tilt or wobble during sliding due to excessive gaps, nor will it jam due to excessive friction caused by insufficient gaps. During operation, when the obstacle post 2 is subjected to compressive force or the elastic force of the return spring, it can slide smoothly and linearly back and forth along the through hole 103, ensuring that the obstacle post 2 can accurately extend or retract the obstacle plate, stably form or remove ice hockey training obstacles, and at the same time reduce the wear between the obstacle post 2 and the inner wall of the through hole 103, extending the service life of the components.

[0033] The traction rope 4 is provided in four sets, and the four sets of traction rope 4 are respectively connected to the four sets of servo motors 3.

[0034] Furthermore, the four sets of servo motors 3 are the core components that provide power, and the four sets of traction ropes 4 are the connecting parts that transmit power. The two adopt a one-to-one connection method. During operation, each set of servo motors 3 can independently drive the corresponding winding shaft to perform winding or unwinding operations, thereby driving the set of traction ropes 4 connected to it to move synchronously. This one-to-one correspondence configuration allows the four sets of traction ropes 4 to obtain controllable traction force, apply force to the limiting tray from four different directions, ensure the balanced distribution of traction force, avoid excessive force on one side, and provide power for the subsequent smooth movement of the limiting tray and driving the vertical column to squeeze the circular abutment.

[0035] The traction rope 4 is a wear-resistant nylon braided rope, and an anti-detachment buckle is provided at the connection between the traction rope 4 and the winding shaft 301.

[0036] Furthermore, the traction rope 4 is made of wear-resistant nylon braided rope, which has strong tensile and wear resistance. During the repeated winding, unwinding, and pulling of the limiting tray with the winding shaft 301, it can withstand continuous tension and is not prone to breakage or wear. It is suitable for the frequent start-stop requirements of the device. The anti-detachment buckle set at the connection between the traction rope 4 and the winding shaft 301 can firmly lock the connection position of the two, preventing the traction rope 4 from loosening or slipping off the winding shaft 301 when the winding shaft 301 rotates at high speed or the traction force is large. This ensures that the traction force can be stably and continuously transmitted to the limiting tray through the traction rope 4, ensuring the power transmission of the entire obstacle device.

[0037] In this embodiment, the specific implementation is as follows: the bottom plate 1 serves as the basic support carrier of the entire device. Two sets of support plates 101 fixedly connected to its upper side stably support the barrier plate 102. Multiple sets of through holes 103 on the surface of the barrier plate 102 provide a sliding path for the barrier post 2. The outer diameter of the barrier post 2 is adapted to the inner diameter of the through holes 103 to ensure smooth reciprocating sliding. A return spring 202 is fixedly connected between the circular abutment plate 201 fixed at the bottom of the barrier post 2 and the barrier plate 102. The return spring 202 is sleeved on the outside of the barrier post 2 to ensure the coaxiality of the extension and retraction. The outer wall of the arc-shaped rubber buffer head at the top of the barrier post 2 is provided with anti-slip texture to buffer the impact of the ice hockey and control the rebound trajectory. At the corner of the upper end face of the lower base plate 1, four sets of servo motors 3 are arranged in a circular array with the limiting tray 5 as the center, and are connected to four sets of traction ropes 4 one by one. The traction ropes 4 are wear-resistant nylon braided ropes. Anti-slip buckles are provided at the connection between the traction ropes 4 and the winding shaft 301 at the output end of the servo motor 3 to prevent slippage. The other end of the traction rope 4 is clamped in the locking holes 501 evenly distributed around the circumference of the limiting tray 5 through the U-shaped plate 502. The limiting tray 5 is fixedly connected to the vertical column 6. The lower part of the vertical column 6 is fixed to the expansion plate 7, and the end away from itself is hinged to the universal wheel 8. The universal wheel 8 rolls in contact with the upper end face of the lower base plate 1 to assist the vertical column 6 to move smoothly. During operation, four sets of servo motors 3 can be controlled to start synchronously or separately, driving the corresponding winding shaft 301 to wind or unwind the traction rope 4. The traction force is transmitted to the limit tray 5 through the return plate 502, driving the vertical column 6 to move synchronously. The expansion plate 7 and the universal wheel 8 further ensure the stability of the vertical column 6. The moving vertical column 6 squeezes the circular abutment plate 201, driving the obstacle column 2 to extend upward along the through hole 103 to form the obstacle plate 102 and form a training obstacle. When the servo motor 3 rotates in the opposite direction to unwind the traction rope 4 and the squeezing force disappears, the reset spring 202 releases the elastic potential energy, pushing the circular abutment plate 201 to drive the obstacle column 2 to reset, realizing the rapid switching of ice hockey training obstacles. The entire process ensures stable power transmission, smooth operation of components, and low wear.
