Description

Technical Field

[0001] The invention relates to the technical field of sports equipment, and is a multi-directional plug-in gas pressure detection device used in an airbag-type boxing target support frame, and in particular to a multi-directional plug-in gas pressure detection device used for a multi-cavity airbag-type boxing target. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The airbag-type boxing target has a better hitting feel. The intelligent boxing target made with it uses the principle of Boyle's law to detect the air pressure inside the airbag cavity and calculate the hitting force. When taking pressure on a multi-airbag-type boxing target, it is necessary to install multiple independent airtight components and pressure-taking devices to collect gas pressure data while hitting.

[0004] However, the connection parts between the hard supporting structure of the traditional boxing target and the airtight pressure-taking device cannot solve the problem of structural loosening caused by strong vibration. The airbag also requires specially designed soft air pipes and hard connectors, which are prone to loosening and damage. At the same time, the traditional pressure-taking method has high requirements on the processing accuracy of airtight components and supporting parts. When air loss occurs in the cavity, the air in the airbag cavity cannot be replenished in time, resulting in excessive negative pressure inside the cavity when the airbag rebounds, affecting the gas pressure detection value.

[0005] How to further solve the defects in the existing technology will be of great significance. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Figure 1-4 An embodiment of a multi-directional plug-in gas pressure detection device provided by the present invention.

[0031] Please refer to Figure 1-4 The embodiment includes a circuit board 1, an air pressure sensor module 2, a gas quick-connection 3, a gas one-way valve 4, a communication interface 5, an airtight tee 6 and a shell component 7, wherein the shell component 7 is used to support the components, and the airtight tee 6 includes three interfaces, wherein the first interface is connected to the gas one-way valve 4, and the second interface is connected to the gas quick-connection 3. The gas quick-connection 3 is connected to the air pressure sensor module 2, and the air pressure sensor module 2 is arranged on the circuit board 1 and connected to the communication interface 5. The communication interface 5 in this embodiment uses an RJ45 interface.

[0032] The present embodiment also includes a three-chamber airbag 29, which has a groove. Under all surfaces of the groove, a fixing frame 24 is provided in the airbag 29. The fixing frame 24 is a built-in fixing frame of the vulcanization process airbag. A support frame 22 is provided on the surface of the groove. A support frame opening 23 is provided on the surface of the support frame 22. A connecting hole 25 matching the support frame opening 23 is provided on the surface of the groove of the airbag 29. The support frame 22 and the fixing frame 24 are fixed by screws 26 or welding.

[0033] Two partitions 28 are provided inside the groove, and the two partitions 28 separate a space. The outer shell component 7 is provided in the space and is fixedly connected to the partitions 28 through threaded holes 30 and bolts 27. The outer shell component 7 is 10 mm away from the support frame 22 at the bottom of the groove, which is convenient for placing power and signal cables.

[0034] The contact surface between the airbag 29 and the shell member 7 is provided with an air hole 19, and the air hole 19 is connected to the third interface of the airtight tee 6. In this embodiment, the number of air holes 19 is 3, and one air hole 19 is distributed on each contact surface between the airbag 29 and the shell member 7. Accordingly, the number of the gas quick-connect straight-through 3, the gas one-way valve 4 and the airtight tee 6 is three respectively.

[0035] In one embodiment, the airbag 29 is made of a high-resilience TPU material for impact testing.

[0036] In one embodiment, the surface of the outer shell member 7 is coated with a Pu adhesion layer 8, which can improve the sealing effect.

[0037] In one embodiment, the air pressure sensing module 2 includes an air pressure sensor, a circuit substrate, an integrated circuit, and a power indicator light.

[0038] In one embodiment, a handle is further included, and the handle is connected to the outer shell member 7 to facilitate the removal of the entire detection device from the airbag.

[0039] In one embodiment, a vent hole is provided on a side of the housing member 7 located on the gas one-way valve.

[0040] When the corresponding cavity in the three-chamber airbag 29 is squeezed by external force, the internal gas is discharged through the air hole 19 into the airtight tee 6. At this time, the gas one-way valve 4 is reversely cut off, and the pressure is transmitted to the air pressure sensor module 2 through the gas quick-fit straight through 3. The pressure value is output through the RJ45 interface.

[0041] When the device and the partition 28 are locked, the corresponding hole and the corresponding airbag are connected, and the air pressure detection condition is achieved. After the detection condition is achieved, if there is air pressure loss in the cavity of the airbag 29 that is transparent to the hole 19, and the negative pressure in the cavity during the airbag rebound is greater than the gas check valve threshold 4, air enters through the gas check valve 4 connected to the airtight tee 6 to achieve a supplementary balance.

[0042] In summary, the embodiment provided by the present invention can reduce the occurrence of structural loosening caused by strong vibration by inserting the detection device into the airbag and fixing it with the airbag, and can also conveniently disassemble and assemble the device, and can automatically replenish the gas in the airbag, optimizing the hard support structure of the airbag-shaped boxing target. The use of this device does not require complex pressure-taking airtight matching parts, and also reduces the processing accuracy requirements of the airbag, and reduces the wear of the airbag and the hard fixed support. The present invention solves the problem of multi-cavity internal air pressure detection of the airbag-type boxing target, performs pressure detection on the catheter-free ring-shaped three-segment airbag, and automatically replenishes the gas in the airbag.
