Description

Technical Field

[0001] This invention relates to the field of training equipment technology, specifically to a landing protection device for depth jump training with linkage damping buffer. Background Technology

[0002] Depth jump training is a core method for developing explosive power, jumping ability, and lower limb core strength. It is widely used in competitive sports, physical training, fitness rehabilitation, and other fields. The training principle involves the trainee falling from a fixed-height platform and then quickly jumping again after landing, thereby stimulating the lower limb muscles and improving neural recruitment and dynamic explosive power. However, the impact force upon landing in depth jump training is extremely high, and conventional training protective equipment has many deficiencies, which can easily lead to sports injuries such as ankle sprains, knee wear and tear, and lower back strain. It is difficult to balance training safety and training effectiveness.

[0003] Currently, most traditional depth jump training protective devices on the market are simple foam pads, rubber cushioning pads, or fixed damping cushioning structures, offering limited functionality. Foam pads and rubber pads provide only basic flexible cushioning, with no adjustable cushioning force. This makes them unsuitable for trainees of different weights and training heights, failing to adapt to varying landing impacts. Overly soft cushioning can cause the trainee to lose balance upon landing, while overly stiff cushioning cannot effectively absorb the impact force, resulting in extremely poor protection. The few training devices that incorporate damping cushioning structures typically have fixed damping parameters, unable to dynamically adjust the cushioning resistance based on training intensity and the trainee's body type, leading to poor adaptability.

[0004] Meanwhile, existing protective devices cannot adapt to the cyclical training characteristics of depth jump training, which involves "landing-second take-off-landing again." Most of them are in a buffered or rigid support state throughout the entire process. In a fully buffered state, when the trainee lands for the first time and takes the second jump, the buffer platform will deform and sink, failing to provide stable support for the second jump, significantly reducing the efficiency of take-off force and affecting training quality. In a fully rigid support state, although the take-off stability can be guaranteed, the buffer protection function is completely lost, and the impact of landing is directly applied to the human body, resulting in an extremely high risk of sports injury. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a landing protection device for depth jump training with linkage damping buffer, which solves the problems of fixed buffering parameters, inability to automatically switch support buffering modes, inability to balance training stability and protection, poor adaptability, and low level of intelligence in existing depth jump training protection devices.

A sealing ring is provided on the outer side of the piston disc, and the sealing ring is tightly attached to the inner side of the movable chamber. A partition is fixedly connected to the middle of the liquid storage chamber. A first flow port is opened on the lower outer side of the outer shell, and a second flow port is opened on the upper outer side of the outer shell. A one-way valve is fixedly connected to the middle of the partition. Small holes are opened at the four corners of the partition. A flow regulating component is provided at the upper end of the liquid storage chamber.

[0007] Preferably, the flow regulating component includes multiple plugs extending through the upper end of the liquid storage tank. The upper end of each plug has a threaded section, and the plug is threadedly connected to the liquid storage tank through the threaded section. A hexagonal block is fixedly connected to the top of the threaded section.

[0008] Preferably, a sealing plate is provided on the outside of the bolt rod, and the sealing plate is fixedly connected to the upper side of the inner wall of the liquid storage tank.

[0009] Preferably, a sealing gasket is fitted around the lower end of the bolt rod, and the lower end of the bolt rod passes through the interior of a fine hole.

[0010] Preferably, the lower left side of the jumping platform has an opening, and T-shaped slide rails are provided at both the front and rear ends of the opening. Fixing plates are fixedly connected to both the left and right ends of the T-shaped slide rails. Ear plates are fixedly connected to the outer sides of the front and rear ends of the fixing plates. The ear plates are fixedly connected to the base plate and the jumping platform respectively.

[0011] Preferably, trapezoidal pads that can slide left and right are provided on the outer sides of both the left and right ends of the T-shaped slide rail, and the upper side of the trapezoidal pads is provided with an inclined surface for cooperating with the tray.

[0012] Preferably, a gear is rotatably connected to the upper center of the base plate, and toothed plates are meshed on both the front and rear sides of the gear. A connecting plate is fixedly connected to one opposite end of the toothed plate, and the end of the connecting plate is fixedly connected to the outside of the trapezoidal pad. A limiting plate is provided on one opposite side of the toothed plate, and the lower end of the limiting plate is fixedly connected to the upper side of the base plate.

[0013] Preferably, a control box is fixedly connected to the lower inner wall of the platform, an electric push rod is provided on the left side of the control box, the electric push rod is fixedly connected to the middle of the fixed plate, and the drive end of the electric push rod is fixedly connected to the middle of the outer side of the connecting plate.

[0014] Preferably, a step is fixedly connected to the right side of the platform, an L-shaped plate is provided at the left end of the support plate, the lower end of the L-shaped plate is fixedly connected to the upper left side of the base plate, and side plates are provided on both the front and rear sides of the support plate, with the lower ends of the side plates fixedly connected to the upper side of the base plate.

[0015] Preferably, a method of using a linkage damping buffer landing protection device for depth jump training includes the following steps: S1. The user stands on the diving platform, and the second pressure sensor detects the pressure and confirms that the user is in place; S2. When the user jumps onto the support plate, the first pressure sensor detects the landing pressure. At this time, the trapezoidal pad supports the support plate to ensure the stability of the jump. S3. After the user jumps a second time, the pressure of the first pressure sensor disappears, and the control box controls the electric push rod to start. Through the linkage of the connecting plate, toothed plate and gear, the trapezoidal pad is displaced and the support on the support plate is released. S4. When the user lands again, the support plate, in conjunction with the damping structure, provides cushioning protection. S5. When the user conducts the next training session, the control box controls the electric push rod to start, which, through the linkage of the connecting plate, toothed plate and gear, drives the trapezoidal pad block to move and reset and support the support plate.

[0016] Working principle: During training, the user stands on the jumping platform. The second pressure sensor detects the pressure signal to confirm the user's positioning. The user jumps from the platform onto the support plate. The first pressure sensor detects the landing pressure. At this time, the trapezoidal pad supports the support plate, ensuring the user's stable second jump. After the user's second jump and departure from the support plate, the pressure signal from the first pressure sensor disappears. The control box receives the signal and controls the electric push rod to retract. The electric push rod pulls the connecting plate to move. One side of the connecting plate drives the corresponding trapezoidal pad to slide unidirectionally. At the same time, in conjunction with the bidirectional meshing transmission of the toothed plate and gear, the other side of the trapezoidal pad slides in the opposite direction. The two trapezoidal pads move synchronously in opposite directions, completely releasing the rigid support on the bottom of the support plate. When the user falls onto the tray again, the tray is pressed down, causing the lifting column, piston disc, and sealing ring to descend. This forces the oil under the piston disc inside the outer casing to be squeezed out through the first flow port. The oil then flows through the fine hole and the second flow port into the upper cavity of the piston disc. The flow-limiting effect of the fine hole provides landing damping. The bolt can be rotated by the hexagonal block, using threaded transmission to insert the bolt into the fine hole, adjusting the degree of blockage and thus the magnitude of the buffering resistance. After a single training cycle, the electric push rod returns to its original position and extends. Through the linkage of the connecting plate, toothed plate, and gears, it drives the trapezoidal pads on both sides to move synchronously towards each other along the T-shaped slide rail. The trapezoidal pads, through their upper inclined surfaces, press against the bottom ends of the tray, precisely driving the tray and bottom lifting structure to return to their original position. The oil at the top of the outer casing flows back through the second flow port, the fine hole, the one-way valve, and the first flow port to the lower cavity of the outer casing. The one-way valve accelerates the oil return speed, improving the tray's reset efficiency and completing one training cycle.

[0017] This invention provides a landing protection device for depth jump training with linked damping buffer. It has the following beneficial effects: 1. This invention, through the setting of pressure sensors, electric push rods, gear and toothed plate linkage structures, and trapezoidal pads, achieves intelligent automatic switching between the device's support mode and buffering mode. It perfectly adapts to the cyclical training logic of depth jump training: "fall and take-off, second flight, and second landing." During the initial landing and take-off phase, the trapezoidal pads rigidly support the support plate, preventing deformation and sinking of the support plate, and providing stable force support for the trainee's second jump, effectively ensuring the standardization of training movements and training quality. During the second landing phase, the rigid support is automatically released, and flexible buffering is achieved through a hydraulic damping structure, effectively dissipating the impact force of landing and fundamentally reducing the risk of sports injuries to the ankles, knees, lower back, and other parts of the body. This completely solves the core problem that traditional equipment cannot simultaneously ensure training stability and landing protection.

[0018] 2. This invention adjusts the effective flow area of ​​the fine orifice by raising and lowering the threaded rod, allowing for flexible and precise adjustment of the hydraulic damping based on the trainee's weight, platform height, and training intensity. This adapts to different training groups and scenarios, overcoming the drawbacks of traditional damping devices with fixed parameters and poor adaptability. Simultaneously, the double-sealing structure of the sealing plate and sealing gasket effectively prevents hydraulic oil leakage, ensuring the stability and consistency of the damping effect, resulting in a longer equipment lifespan and a better training experience.

The middle part of the liquid storage tank 6 is fixedly connected to... A partition 10 is connected to the outer side of the lower end of the outer shell 2, and a first flow port 11 is opened on the outer side of the upper end of the outer shell 2. A second flow port 12 is opened on the outer side of the upper end of the outer shell 2. A one-way valve 14 is fixedly connected to the middle of the partition 10. Small holes 13 are opened at the four corners of the partition 10. A flow regulating component is provided at the upper end of the liquid storage tank 6. The flow regulating component includes multiple plug rods 15 passing through the upper end of the liquid storage tank 6. A threaded section 16 is provided at the upper end of the plug rod 15. The plug rod 15 is threaded to the liquid storage tank 6 through the threaded section 16. A hexagonal block 17 is fixedly connected to the top of the threaded section 16. A sealing plate 18 is provided on the outside of the plug rods 15. The sealing plate 18 is fixedly connected to the upper side of the inner wall of the liquid storage tank 6. A sealing gasket 19 is sleeved on the outside of the lower end of the plug rod 15. The lower end of the plug rod 15 passes through the inside of the small hole 13.

[0023] Specifically, the base plate 1 serves as the mounting base for the entire device. A platform 31 is fixedly connected to its right end by welding. A second pressure sensor 32 is embedded in the upper surface of the platform 31 to detect whether the user is standing in position. A housing 2, serving as a support and guide structure, is vertically fixed to each of the four corners of the upper surface of the base plate 1. (Refer to...) Figure 1 and Figure 2 Four outer shells 2 are connected at their upper ends by lifting columns 3 capable of reciprocating up and down. A horizontal support plate 4 is fixedly connected to the top of the four lifting columns 3, providing a landing area for the user. A first pressure sensor 5 is installed in the center of its upper side to detect the pressure signal generated when the user lands. The lifting columns 3 and the outer shells 2 are in a sliding fit to ensure that the support plate 4 can move smoothly and vertically downwards when subjected to impact. (Refer to...) Figure 1 and Figure 3A damping buffer mechanism is located between the outer casing 2 and the lifting column 3. A liquid storage tank 6 is fixedly connected to the outer side of each outer casing 2. The liquid storage tank 6 is hollow and contains a movable chamber 7, which serves as a hydraulic cylinder. The bottom of the lifting column 3 extends into the movable chamber 7 and is fixedly connected to a piston disc 8, which can move up and down inside the movable chamber 7. A sealing ring 9 is provided on the outer periphery of the piston disc 8, and the outer edge of the sealing ring 9 fits tightly against the inner wall of the movable chamber 7 to prevent hydraulic oil from leaking directly between the upper and lower cavities of the piston disc 8. (Refer to...) Figure 3 To dampen the descent of the pallet 4, a partition 10 is fixedly connected horizontally in the middle of the liquid storage tank 6, dividing the interior of the liquid storage tank 6 into upper and lower chambers. A first flow port 11 is provided on the lower outer side of the outer shell 2, and a second flow port 12 is provided on the upper outer side. The first flow port 11 communicates with the lower chamber of the liquid storage tank 6, and the second flow port 12 communicates with the upper chamber of the liquid storage tank 6. A one-way valve 14 is fixedly connected in the middle of the partition 10, and small holes 13 are provided at each of the four corners of the partition 10. When the piston disc 8 moves downward, the liquid in the lower chamber enters the lower part of the storage tank 6 through the first flow port 11. After being pressurized, it slowly flows into the upper part of the storage tank 6 through the fine hole 13, and then enters the space above the piston disc 8 through the second flow port 12. The throttling effect of the fine hole 13 creates resistance to the flow of the liquid, thus forming a buffering effect. When the support plate 4 returns to its original position, the liquid mainly flows back from the upper chamber to the lower chamber quickly through the one-way valve 14, achieving rapid reset. In order to adjust the magnitude of the buffering resistance, a flow regulating component is provided at the upper end of the storage tank 6. The flow regulating component includes multiple vertically inserted rods 15 on the top wall of the storage tank 6. Each rod 15 has a threaded section 16 machined at its upper end. The rod 15 is threaded to the top wall of the storage tank 6 through the threaded section 16. A hexagonal block 17 for easy turning with a tool is fixedly connected to the top of the threaded section 16. The lower end of the plug rod 15 is precisely inserted into the fine hole 13 of the partition plate 10. By rotating the hexagonal block 17, the depth of the plug rod 15 inserted into the fine hole 13 can be controlled by the threaded transmission, thereby changing the effective flow cross-sectional area of ​​the fine hole 13 and achieving precise adjustment of the buffer damping force. To ensure sealing, a sealing plate 18 is provided on the outside of all plug rods 15. The sealing plate 18 is fixedly connected to the upper side of the inner wall of the liquid storage tank 6. At the same time, a sealing gasket 19 is also fitted on the outside of the lower end of each plug rod 15 to enhance the sealing effect at the joint between the plug rod 15 and the fine hole 13.

[0024] Please see the appendix Figure 1-4An opening 33 is provided at the lower left end of the diving platform 31. T-shaped slide rails 20 are provided at both the front and rear ends of the opening 33. A fixing plate 21 is fixedly connected to both the left and right ends of the T-shaped slide rails 20. Ear plates 22 are fixedly connected to the outer sides of both the front and rear ends of the fixing plate 21. The ear plates 22 are fixedly connected to the base plate 1 and the diving platform 31 respectively. Trapezoidal pads 23 that slide left and right are provided on the outer sides of both the left and right ends of the T-shaped slide rails 20. An inclined surface 24 for engaging with the support plate 4 is provided on the upper side of the trapezoidal pads 23. A gear 25 is rotatably connected to the upper center of the base plate 1. Gear plates 26 are meshed with on both the front and rear sides of the gear 25. A connecting plate 28 is fixedly connected to the opposite end of the gear plate 26. The end of the connecting plate 28... A limit plate 27 is provided on the opposite side of the toothed plate 26, and the lower end of the limit plate 27 is fixedly connected to the upper side of the base plate 1. A control box 30 is fixedly connected to the lower side of the inner wall of the platform 31. An electric push rod 29 is provided on the left side of the control box 30. The electric push rod 29 is fixedly connected to the middle of the fixed plate 21. The drive end of the electric push rod 29 is fixedly connected to the middle of the outer side of the connecting plate 28. A step 34 is fixedly connected to the right side of the platform 31. An L-shaped plate 35 is provided on the left end of the support plate 4. The lower end of the L-shaped plate 35 is fixedly connected to the upper left side of the base plate 1. Side plates 36 are provided on both the front and rear sides of the support plate 4. The lower end of the side plates 36 is fixedly connected to the upper side of the base plate 1.

[0025] Specifically, to achieve the switching of the support state of the support plate 4, the device also includes a linkage sliding mechanism that can selectively support the support plate 4. This mechanism forms a stable installation fit with the base plate 1 and the platform 31, and forms a functional support and separation fit with the support plate 4. A through opening 33 is opened at the lower left end of the platform 31, and T-shaped slide rails 20 are horizontally arranged on the inner walls of both the front and rear ends of the opening 33. The left and right ends of the T-shaped slide rails 20 are connected by fixing plates 21 to form a stable rectangular guide rail frame. This frame is firmly fixed to the base plate 1 and the platform 31 by the ear plates 22 on the outer sides of its front and rear ends, providing a precise motion reference for the subsequent sliding components. Trapezoidal pads 23 that can slide left and right along the T-shaped slide rails 20 are respectively arranged on the outer sides of the left and right ends of the T-shaped slide rails 20. Each trapezoidal pad 23 has a slope 24 that is higher towards the center and lower towards the outside on its upper side. The slope 24 is used to contact and push against the bottom edge of the support plate 4. When the two trapezoidal pads 23 move towards each other to a predetermined position, their inclined surfaces 24 can fully support the support plate 4, providing it with rigid support; when they move away from each other, they completely disengage from the bottom of the support plate 4, releasing the support. To achieve synchronous reverse movement of the two trapezoidal pads 23, a gear 25 is rotatably connected at the upper middle position of the base plate 1. Gear plates 26 are meshed on the front and rear sides of the gear 25, respectively. A connecting plate 28 is fixedly connected to the end of each gear plate 26 away from the gear 25, and the end of the connecting plate 28 is fixedly connected to the outer wall of the corresponding trapezoidal pad 23. This gear and tooth plate transmission structure ensures that when one tooth plate 26 moves, the other tooth plate 26 will move in the opposite direction by an equal distance, thereby driving the two trapezoidal pads 23 to achieve precise synchronous sliding towards or away from each other. To ensure the smooth movement of the toothed plate 26, a limiting plate 27 is provided on its opposite side. The lower end of the limiting plate 27 is fixedly connected to the upper side of the base plate 1, guiding and limiting the linear movement of the toothed plate 26. The driving source of this linkage sliding mechanism is an electric push rod 29 located on the lower side of the inner wall of the platform 31. The housing of the electric push rod 29 is fixed in the middle of the fixed plate 21 located between the two T-shaped slide rails 20, and its driving end is hinged to the middle of the outer side of one of the connecting plates 28. The operation logic of the entire device is controlled by a control box 30 fixed to the inner wall of the platform 31. The control box 30 is electrically connected to the first pressure sensor 5, the second pressure sensor 32, and the electric push rod 29. According to the change of pressure signal, the control box 30 precisely controls the extension and retraction of the electric push rod 29, thereby driving the entire linkage sliding mechanism to complete the supporting or releasing action of the support plate 4.

[0026] A method for using a landing protection device for depth jump training with linkage damping buffer includes the following steps: S1. The user stands on the platform 31, and the second pressure sensor 32 detects the pressure and confirms that the user is in place; S2. When the user jumps onto the support plate 4, the first pressure sensor 5 detects the landing pressure. At this time, the trapezoidal pad 23 supports the support plate 4 to ensure the stability of the jump. S3. After the user jumps for the second time, the pressure of the first pressure sensor 5 disappears, and the control box 30 controls the electric push rod 29 to start. Through the linkage of the connecting plate 28, the toothed plate 26 and the gear 25, the trapezoidal pad 23 is displaced and the support of the support plate 4 is released. S4. When the user lands again, the support plate 4, in conjunction with the damping structure, provides cushioning protection. S5. When the user conducts the next training session, the control box 30 controls the electric push rod 29 to start, which, through the linkage of the connecting plate 28, the toothed plate 26 and the gear 25, drives the trapezoidal pad 23 to move and reset and support the support plate 4.

A landing protection device for depth jump training with linkage damping buffer as described in claim 8, characterized in that, The right side of the platform (31) is fixedly connected to a step (34), the left end of the support plate (4) is provided with an L-shaped plate (35), the lower end of the L-shaped plate (35) is fixedly connected to the upper left side of the base plate (1), and the front and rear sides of the support plate (4) are provided with side plates (36), the lower end of the side plates (36) is fixedly connected to the upper side of the base plate (1).

10. A method of using a linkage damping buffer landing protection device for depth jump training, comprising using the linkage damping buffer landing protection device for depth jump training as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. The user stands on the platform (31), and the second pressure sensor (32) detects the pressure and confirms that the user is in place; S2. When the user jumps onto the support plate (4), the first pressure sensor (5) detects the landing pressure. At this time, the trapezoidal pad (23) supports the support plate (4) to ensure the stability of the jump. S3. After the user jumps for the second time, the pressure of the first pressure sensor (5) disappears, and the control box (30) controls the electric push rod (29) to start. Through the linkage of the connecting plate (28), toothed plate (26) and gear (25), the trapezoidal pad (23) is displaced and the support of the support plate (4) is released. S4. When the user lands again, the support plate (4) works with the damping structure to provide buffer protection. S5. When the user conducts the next training session, the control box (30) controls the electric push rod (29) to start, and through the linkage of the connecting plate (28), toothed plate (26) and gear (25), it drives the trapezoidal pad (23) to move and reset and support the support plate (4).
