Description

Technical Field

[0001] This utility model relates to a shock-absorbing device for equipment, and more particularly to a shock-absorbing device for sports equipment applied in the field of sports equipment. Background Technology

[0002] As a common striking training tool, the sports punching bag is a device that uses striking as its core training method. It is mainly used in physical training, combat training, and strength training. Its basic structure usually includes a striking body (such as a cloth bag or a hard outer shell) and internal filling. Through the design of the filling material and density, different striking feedback and cushioning effects are provided. It is widely used in home fitness, children's physical training, and commercial combat sports venues.

[0003] Chinese patent CN207076083U discloses a vertical boxing device, including a base, a shock-absorbing structure, and a sandbag body. The shock-absorbing structure connects the base and the sandbag body, and includes shock absorbers and columns. There are at least three shock absorbers, which are evenly distributed around the columns. A central tube is provided inside the sandbag body, and the central tube is connected and fixed to the columns. This utility model provides a vertical boxing device with a simple structure, convenient installation, and good practicality.

[0004] Chinese patent CN205924914U discloses a punching bag. The punching bag includes a base plate, a fixed rod, and a punching bag mounted on the fixed rod. A lower buffer plate is provided on the base plate, and an upper buffer plate is provided at the lower end of the fixed rod. An elastic component is provided between the upper and lower buffer plates. The elastic component is fixedly connected to both the upper and lower buffer plates. The punching bag provided by this invention, on the one hand, improves the shock absorption function of the elastic component, enabling it to be used for a longer period; on the other hand, it reduces the impact force on the bottom of the base plate, making the punching bag more stable.

[0005] Traditional sports sandbags are mostly designed with fixed cushioning. Children's sandbags are usually filled with high-density sponge, which can protect joints, but the excessive cushioning results in weak force feedback. The sandbag is also prone to excessive deformation when hit, which cannot meet the explosive power training needs of adults. Adult sandbags are filled with hard materials such as sand and rubber granules, which have strong support, but children are prone to wrist and finger joint contusions due to excessive impact when using them. They need to be equipped with special equipment for children, which increases the procurement cost. Utility Model Content

[0006] The technical problem this utility model aims to solve in response to the aforementioned existing technologies is that the cushioning performance of traditional sports sandbags is mostly fixed in design. Children's sandbags are usually filled with high-density sponge, which can protect joints, but the excessive cushioning results in weak force feedback. The sandbag is prone to excessive deformation when hit, which cannot meet the needs of adults' explosive power training. Adult sandbags are filled with hard materials such as sand and rubber granules, which have strong support, but children are prone to wrist and finger joint contusions due to excessive impact when using them. Additional children's special equipment is required, which increases the procurement cost.

[0007] To address the aforementioned problems, this utility model provides a shock-absorbing device for sports equipment, including a sports sandbag assembly. The outer end of the sports sandbag assembly is equipped with a switchable mode airbag assembly, which contains a replaceable multi-layer airbag assembly. The sports sandbag assembly includes a sandbag body, with a built-in filling column fixedly connected to the middle of the sandbag body. A stable conical base is installed at the lower end of the built-in filling column, and multiple anti-slip suction cups are fixedly connected to the lower end of the stable conical base. The multiple anti-slip suction cups are arranged in a ring at equal intervals. Multiple adjustable damping buffers are fixedly connected to the upper end of the stable conical base, arranged in a ring at equal intervals. The switchable mode airbag assembly includes an outer airbag layer fixedly connected to the outside of the built-in filling column. A pump is fixedly connected to the middle of the upper end of the stable conical base, and a hose is installed at the output end of the pump. A valve block is fixedly connected to the lower end of the sandbag body.

[0008] In the shock absorption device of the aforementioned sports equipment, this solution achieves basic shock absorption and modular cushioning functions through the synergy of the sports sandbag equipment component and the switchable mode airbag component, making it suitable for regular children's and adults' training scenarios.

[0009] As a further improvement of this application, the valve block and the pump are interconnected, and a mode switching controller is fixedly connected to the lower right side of the sandbag body.

[0010] As a further improvement of this application, a sponge buffer layer is fixedly connected to the outer side of the outer airbag layer, and an anti-slip contact layer is fixedly connected to the outer side of the sponge buffer layer.

[0011] As a further improvement to this application, the replaceable multi-layer airbag assembly includes a hollow connecting strip, the left end of which is connected to a valve block.

[0012] As a further improvement of this application, the replaceable multi-layer airbag assembly includes airbag layer one, airbag layer two, and airbag layer three fixedly connected to the outer airbag layer, with airbag layer one, airbag layer two, and airbag layer three arranged sequentially from the outside to the inside.

[0013] As a further improvement to this application, the lower ends of airbag layer one, airbag layer two, and airbag layer three are respectively fixedly connected with connecting valves, and the right end of the hollow connecting strip is connected to the connecting valves.

[0014] As another improvement of this application, the inner end of the hollow connecting strip is fixedly connected to a plurality of gas transmission pipes whose left and right ends are respectively connected to the valve block and the corresponding connecting valve.

[0015] In summary, this solution achieves a precise match between the training needs of children and adults through the synergy of the exercise sandbag equipment component and the switchable mode airbag component. In children's mode, the outer airbag layer, combined with the sponge cushioning layer, can fully absorb impact force. With the weak damping setting of the adjustable damper, it can prevent joint injuries and equipment swaying imbalance in children. In adult mode, the airbag layer retains appropriate cushioning and support feedback, and the strong damping of the damper can quickly suppress vibration, ensuring the stability and continuity of explosive power training. No additional special equipment is required, and if a leak is found in a certain airbag, only the damaged airbag needs to be replaced, and the lower airbag can be opened to continue use. There is no need to replace the entire outer airbag layer, which can significantly reduce maintenance costs and equipment downtime in commercial settings. It is especially suitable for scenarios with high hitting frequency, taking into account the training needs of different groups and the economy of commercial scenarios. Attached Figure Description

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figures 2-5 This invention illustrates a shock-absorbing device for sports equipment, including a sports sandbag assembly 1. A switchable-mode airbag assembly 2 is located at the outer end of the sports sandbag assembly 1. The switchable-mode airbag assembly 2 contains a replaceable multi-layer airbag assembly 3. The sports sandbag assembly 1 includes a sandbag body 100. A column 101 with internal filling material is fixedly connected to the middle of the sandbag body 100. A stable conical base 102 is installed at the lower end of the column 101. Multiple anti-slip suction cups 103 are fixedly connected to the lower end of the stable conical base 102. The multiple anti-slip suction cups 103 are arranged equidistantly in a ring. The upper end of the fixed conical base 102 is fixedly connected to a plurality of adjustable damping buffers 104 arranged in a ring at equal intervals. LORD Magneto-Rheological (MR) dampers can be used. The switchable mode airbag assembly 2 includes an outer airbag layer 200, which is fixedly connected to the outside of the built-in filling column 101. A pump 201 is fixedly connected to the middle of the upper end of the fixed conical base 102. Model 830-1006 can be selected. A hose 202 is installed at the output end of the pump 201. A valve block 203 is fixedly connected to the lower end of the sandbag body 100.

[0028] The valve block 203 and the pump 201 are connected to each other. A mode switching controller 206 is fixedly connected to the lower right side of the sandbag body 100. The mode switching controller 206 is based on an AVR microcontroller. A sponge buffer layer 204 is fixedly connected to the outer side of the outer airbag layer 200. An anti-slip contact layer 205 is fixedly connected to the outer side of the sponge buffer layer 204.

[0029] Figures 2-5This solution demonstrates how the synergy between the sports sandbag equipment component 1 and the switchable mode airbag component 2 achieves basic shock absorption and modular cushioning functions, adapting to typical training scenarios for children and adults. The sandbag body 100 serves as the striking main body, with a centrally reinforced rigidity via an internally filled column 101. A stable conical base 102 at the lower end distributes the center of gravity. Anti-slip suction cups 103 at the lower end of the base are arranged in a ring at equal intervals to adhere to the ground and prevent slippage. An adjustable damping buffer 104 at the upper end of the base is arranged in a ring at equal intervals and connected to the internally filled column 101 to absorb vertical vibrations. The switchable mode... The airbag assembly 2 has an outer airbag layer 200 wrapped around the outside of the internal filling column 101. The pump 201 is fixed to the middle of the upper end of the base to provide air supply. The pump 201 is connected to the valve block 203 via the hose 202 and fixed to the lower end of the sandbag body 100. The valve block 203 controls the pressure of the gas entering the outer airbag layer 200. The outer airbag layer 200 is connected in sequence to a sponge buffer layer 204 for secondary buffering and an anti-slip contact layer 205 to prevent impact and slippage. The mode switching controller 206 is fixed to the lower right side of the sandbag body 100 to trigger the buffer mode switching.

[0030] The user selects a mode, child mode, via mode switching controller 206. The controller command is transmitted to valve block 203, which controls pump 201 to inflate external airbag layer 200 to 80% air pressure, creating a soft state. In conjunction with sponge buffer layer 204, the external airbag layer 200 absorbs 70% of the impact force through gas compression during a strike, preventing excessive stress on the child's joints. Simultaneously, mode switching controller 206 sends a signal to adjustable damping buffer 104, adjusting its damping force to a weak setting. This reduces the viscosity of the internal magnetorheological fluid and decreases the spring rebound resistance. When the child strikes and generates a slight vertical vibration, the spring compression of the buffer increases, improving vibration absorption efficiency and preventing the child from becoming unbalanced due to the device's swaying.

[0031] In adult mode, valve block 203 controls pump 201 to inflate external airbag layer 200 to 30% air pressure and hard state. When hit, the airbag deforms slightly, and 30% of the impact force is absorbed by sponge buffer layer 204, while maintaining sufficient support feedback to adapt to explosive power training. Simultaneously, damping adjustable buffer 104 switches to high level. The viscosity of magnetorheological fluid increases, and the spring rebound resistance increases. When an adult hits and generates strong vertical vibration, the spring compression of the buffer is limited to 20% of its original length to avoid excessive deformation and the feeling of force loss. At the same time, the high damping quickly suppresses vibration to ensure that the device has no resonance when hitting at high frequency.

[0032] Second implementation method:

[0033] Figure 1 , Figures 6-7This invention illustrates a shock-absorbing device for sports equipment. A replaceable multi-layer airbag assembly 3 includes a hollow connecting strip 300. The left end of the hollow connecting strip 300 is connected to a valve block 203. The replaceable multi-layer airbag assembly 3 includes airbag layer one 301, airbag layer two 3010, and airbag layer three 3011 fixedly connected to the outer airbag layer 200. Airbag layer one 301, airbag layer two 3010, and airbag layer three 3011 are arranged sequentially from the outside to the inside. A connecting valve 302 is fixedly connected to the lower ends of airbag layer one 301, airbag layer two 3010, and airbag layer three 3011 respectively. The right end of the hollow connecting strip 300 is connected to the connecting valve 302. The inner end of the 0 is fixedly connected to multiple air supply pipes, with the left and right ends respectively connected to the valve block 203 and the corresponding connecting valve 302. When the staff finds through visual inspection that the surface of the first airbag layer 301 is dented, cannot maintain its inflated state after inflation, or the user reports that the touch suddenly becomes hard when hit, confirming that a certain airbag is leaking, the multi-layer airbags can be replaced individually. For example, if only the leaking first airbag layer 301 is replaced, the connecting valve 302 of the corresponding airbag layer is closed, the next layer of airbag layer 3010 and the connecting valve 302 are opened, and the airbag is inflated by the pump 201. There is no need to replace the entire outer airbag layer 200. It can be used as an optional accessory for commercial occasions where the frequency of being hit is high, reducing maintenance costs.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
