Example

[0023] Reference Figure 1-Figure 7 A barbell laser protection device for a gym comprises a base and a barbell rod 8, and barbell plates 9 are symmetrically arranged at both ends of the barbell rod 8.

[0024] In this embodiment, two or more barbell plates 9 are provided at each end of the barbell rod, and the relative number can be selected by the user. A magnet is provided on the outer end surface of each barbell plate 9 to prevent the barbell plates 9 from falling off from each other and causing personal injury.

[0025] The base includes a vertical plate 1 and a reinforcing rib 2 arranged on one side of the vertical plate 1. A support plate 6 is connected to the top of the vertical plate 1 through a buffer assembly. A bracket 7 is clamped on the top of the support plate 6. When the barbell is not in use, the two ends of the barbell rod 8 are placed in contact with the recessed part of the bracket 7, and an infrared detector 26 is arranged on one side of the support plate 6.

[0026] In the present embodiment, two groups of bases are provided for supporting the barbell rod 8 and the barbell plates 9 at both ends of the barbell rod 8. Specifically, reinforcing ribs 2 are provided on one side of the vertical plate 1 to enhance the supporting strength of the base, and a bracket 7 is provided on the top of the support plate 6. A recess is provided in the bracket 7, and the recess and the end of the barbell rod 8 are fitted and supported, and the bracket 7 and the support plate 6 are fixedly connected to facilitate installation and disassembly, and facilitate the disassembly, storage and transportation of the entire barbell.

[0027] A connecting rod 10 is fixedly connected between the two groups of vertical plates 1, a flap 11 is connected to the surface of the connecting rod 10, and a supporting leg is arranged on the bottom surface of the flap 11 away from the connecting rod 10.

[0028] In this embodiment, a flap 11 is provided under the barbell bar 8. The flap 11 can be flipped down according to the needs of the user. During the push-up, the user can also lie on the flap 11, and the legs are provided on the bottom surface of the flap 11 to maintain the stability of the horizontal structure of the flap 11.

[0029] It also includes: a buffer component arranged in the base, the buffer component includes a support sleeve 3 and a guide rod 4 sleeved in the support sleeve 3, the top end of the guide rod 4 is fixedly connected to the support plate 6, a first spring 5 is arranged between the guide rod 4 and the support sleeve 3, a top column 13 is fixedly installed on the bottom surface of one end of the barbell rod 8, a touch switch 14 is fixedly installed in the support plate 6, the top column 13 and the touch switch 14 are matched, and the touch switch 14 is electrically connected to the infrared detector 26.

[0030] In this embodiment, a guide rod 4 and a first spring 5 are connected between the vertical plate 1 and the support plate 6. When the barbell is not lifted, the weight of the barbell rod 8 and the barbell plates 9 at both ends of the barbell rod 8 press the support plate 6 down until the first spring 5 is completely compressed. At this time, the top column 13 and the touch switch 14 are in contact, and the infrared detector 26 does not work; after the barbell is lifted, the touch switch 14 is reset, and the infrared detector 26 is started to work.

[0031] Specifically, when the barbell is taken off, the infrared detector 26 starts to start and emits infrared rays for detection. When the barbell remains in one position for a long time (preferably 8-10 seconds), the buzzer set in the barbell will alarm and generate an automatic buzzing sound to attract the attention of people around.

[0032] Because when doing a barbell bench press, it is a reciprocating motion, and the barbell will eventually be put back to its original position, which will end the automatic alarm device of the barbell. However, if it is kept in a low position for a long time, preferably 8-10 seconds, an unexpected situation may have occurred, and rescue is urgently needed to avoid accidents.

[0033] A first slide groove 15 is provided in the support plate 6 , and the support sleeve 3 is slidably connected to the first slide groove 15 . A second slide groove 16 is provided in the vertical plate 1 , and the guide rod 4 is slidably connected to the second slide groove 16 .

[0035] It should be noted that the lever is counted by passing through a data storage device and a signal sending module in turn, using the terminal controller and infrared rangefinder, the data storage device and the signal sending module to be electrically connected. Through video acquisition, a photoelectric sensor device is set between the lever and the barbell bracket. After the counting stops, if the photoelectric sensor cannot monitor the lever, a distress alarm will be issued to ensure the safety performance of the smart barbell.

[0036] A grip force sensor assembly is arranged in the barbell bar 8, and is used to monitor the user's pushing status. The grip force sensor assembly includes a grip cover 12. A first cavity 17 is opened in the barbell bar 8 at the position wrapped by the grip cover 12. Pressure sensors 18 are arranged in a circular equidistant array in the first cavity 17. The sensing side of the pressure sensor 18 extends to the outside of the first cavity 17 and is arranged in close contact with the inner wall of the grip cover 12.

[0037] In this embodiment, a grip force sensing assembly is provided in the barbell bar 8, which includes a grip cover 12 and a pressure sensor 18 wrapped in the grip cover 12 in sequence. The pressure sensors 18 are arranged in an equidistant array in the first cavity 17, and at least four groups are provided. The pressure sensors 18 extend to the outside of the barbell bar 8. After the user grabs the barbell bar 8, the hand grip force acts on the pressure sensor 18 wrapped in the grip cover 12, and cooperates with the infrared detector 26 to monitor whether the user has any accidents at all times.

[0038] A protection component is arranged in the barbell bar 8, and is used to protect the safety of the user during exercise. The protection component includes a second cavity 19 opened in the barbell bar 8, and an air bag 25 is arranged in the second cavity 19. The air bag 25 is connected to a gas generator 24, and the gas generator 24 and the infrared detector 26 are electrically connected.

[0039] In this embodiment, when the barbell is kept in one position for a long time (preferably 8-10 seconds), the infrared detector 26 is used to send a signal to the gas generator 24. The gas generator 24 includes an ignition part and a gas generator. After the infrared detector 26 sends a signal, the ignition part is started to burn the gas generator to perform explosive inflation on the airbag 25. The airbag is used to protect the user from accidents during exercise and to provide personal protection in time.

[0040] The barbell rod 8 is located at the opening position of the second cavity 19 and has a sealing plate 20 in a circular equidistant array. The sealing plate 20 is elastically connected to the outside of the second cavity 19, and elastic plungers 23 are provided at both ends of the sealing plate 20. The sealing plate 20 is elastically clamped to the surface of the barbell rod 8 through the elastic plungers 23.

[0041] In this embodiment, a second cavity 19 is opened in the barbell rod 8, and a sealing plate 20 is arranged in a circular equidistant array in the second cavity 19. In the initial state, the sealing plate 20 and the barbell rod 8 are covered to wrap and protect the airbag.

[0043] It should be noted that the sealing plate 20 of the elastic connection structure is exploded by the inflation of the airbag 25. When the airbag is expanded, the sealing plate 20 can be stretched and pulled by the second spring 22 to prevent the sealing plate 20 from being damaged by the airbag, thereby extending the use time of the device while still ensuring the protective function of the airbag 25.

[0044] In the present invention, a recess is opened in the bracket 7, and the recess and the end of the barbell rod 8 are supported by fitting together, and the bracket 7 and the support plate 6 are fixedly connected, which is easy to install and disassemble, and convenient for the disassembly, storage and transportation of the entire barbell.

[0045] When the barbell is not raised, the deadweight of the barbell rod 8 and the barbell plates 9 at both ends of the barbell rod 8 presses the support plate 6 down until the first spring 5 is completely compressed. At this time, the top column 13 and the touch switch 14 are in contact, and the infrared detector 26 does not work; after the barbell is raised, the touch switch 14 is reset, and the infrared detector 26 is started to work, so as to monitor the user's usage status at all times and ensure the user's operation safety.

[0046] The legs are used to adjust the horizontal position of the flap 11. After the adjustment is completed, the operator sits on the flap 11, holds the handle cover 12 with both hands, takes off the barbell, and then starts the operation.

[0047] When the barbell is taken off, the infrared detector 26 starts to start and emits infrared rays for detection. When the barbell remains in one position for a long time (preferably 8-10 seconds), the buzzer set in the barbell will alarm and generate automatic buzzing to attract the attention of people around.

[0048] When the barbell bar 8 is put back on the bracket 7, the first spring 5 is compressed to provide a buffer force during the process of taking and placing the barbell bar 8, thereby ensuring the stability of the equipment and facilitating the taking and placing of the barbell bar 8.

[0049] After the user grabs the barbell bar 8, the hand-held force acts on the pressure sensor 18 wrapped in the grip cover 12, and cooperates with the infrared detector 26 to monitor whether the user has any accidents at all times.

[0050] In the initial state, the sealing plate 20 and the barbell bar 8 are closed to wrap and protect the airbag. The sealing plate 20 of the elastic connection structure is inflated and exploded by the airbag 25. When the airbag is expanded, the second spring 22 can stretch and pull the sealing plate 20 to prevent the sealing plate 20 from being damaged by the airbag. While extending the use time of the device, the protective function of the airbag 25 can still be guaranteed.
