[0002] A barbell is a piece of sports training equipment, which generally includes a barbell bar and weight plates detachably mounted on both ends of the barbell bar. The weight of the barbell can be adjusted by disassembling and replacing the weight plates to meet the needs of different weight training.

[0003] Since barbells have good training effects on strength, endurance, toughness, etc., they are also widely used in military training.

Although there are already barbells with adjustable weights in the prior art, such as the Chinese patent application with announcement number CN116920323A, which discloses a barbell device with synchronously adjustable weights, the barbell device can control different weights to be separated from or connected to the barbell rod by rotating the adjustment knob to link the cam group, thereby achieving the purpose of adjusting the weight.

[0067] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0068] like Figure 3 As shown, the utility model provides a barbell device, including a barbell bar 1, two counterweight assemblies 2 and a driving assembly 3, the two counterweight assemblies 2 are arranged at both ends of the barbell bar 1, the counterweight assembly 2 includes a fixing member 21 and a plurality of counterweight members 22, the plurality of counterweight members 22 are arranged on the fixing member 21, and each counterweight member 22 has a first state connected to the barbell bar 1 and a second state detached from the barbell bar 1; the driving assembly 3 is connected to the fixing member 21, and the driving assembly 3 can drive part or all of the counterweight members 22 to enter the first state according to an electrical signal.

[0069] Before barbell training, according to the user's training needs and goals, the drive component 3 can work through electrical signals, that is, the drive component 3 can control a set number of counterweights 22 to enter the first state according to the electrical signal, that is, a set number of counterweights 22 are connected to the barbell bar 1 to meet the training weight needs. It is convenient for the trainer to control the drive component to adjust the counterweight, avoiding the trainer manually controlling the mechanical structure to adjust the counterweight, which can greatly improve the efficiency and difficulty of weight adjustment.

[0070] like Figure 4As shown, in one embodiment, the driving assembly 3 includes a plurality of connecting members 31 and a driving member 32, wherein the plurality of connecting members 31 are respectively connected to a plurality of counterweight members 22, and the connecting members 31 have a first state of connecting to the barbell bar 1 and a second state of disconnecting from the barbell bar 1; the driving member 32 is connected to the fixing member 21, and is used to drive part or all of the connecting members 31 to connect to or disconnect from the barbell bar 1. The driving member 32 controls the connecting member 31 to enter the first state or the second state, so that the connecting member 31 is connected to or disconnected from the barbell bar 1, and the user can quickly adjust the weight of the counterweight on the barbell bar 1 to adapt to different training stages and intensities. By driving part or all of the connecting members 31 to connect to or disconnect from the barbell bar 1, the driving member 32 can adjust the number of counterweight members 22 connected to or disconnected from the barbell bar 1 as needed, and then can more accurately increase or decrease the weight of the counterweight on the barbell bar 1 as needed, so that different users can adjust the weight of the configuration on the barbell bar 1 as needed.

[0071] It should be understood that the driving member 32 may have one or more driving ends, and one driving end may correspond to multiple connecting members 31 to realize the driving of multiple connecting members 31, or multiple driving ends may be set in a one-to-one correspondence with multiple connecting members 31 to realize that each driving end drives one connecting member 31, or two driving ends may correspond to one connecting member 31 to realize that the two driving ends cooperate to drive one connecting member 31 to enter the first state and the second state respectively.

[0072] like Figure 5 and Figure 6 As shown, in one embodiment, the barbell bar 1 is provided with a plurality of fixing holes 1a, a plurality of connecting members 31 are arranged relative to the plurality of fixing holes 1a, the connecting member 31 is slidably connected to the counterweight member 22, and has a first state of being slidably inserted in the fixing hole 1a and a second state of being detached from the fixing hole 1a, the connecting member 31 is connected to or detached from the counterweight member 22 by means of sliding insertion; the driving member 32 is used to drive the connecting member 31 to be slidably inserted in the fixing hole 1a, or to slide away from the fixing hole 1a.

[0073] In an embodiment in which a plurality of counterweights 22 are arranged along the length direction of the barbell bar 1, when it is necessary to connect the connecting member 31 to the barbell bar 1, the driving member 32 is started, and the driving member 32 drives the connecting member 31 to move, so that the connecting member 31 is slidably inserted into the fixing hole 1a, thereby realizing the connection between the connecting member 31 and the barbell bar 1. When the barbell bar 1 is lifted, the barbell bar 1 can drive the counterweights 22 to move upward through the connecting member 31; when it is necessary to drive the connecting member 31 to disengage from the fixing hole 1a, the driving member 32 drives the connecting member 31 to slide out of the fixing hole 1a, thereby realizing the disengagement of the connecting member 31 from the barbell bar 1.

[0074] In an embodiment in which a plurality of counterweight members 22 are arranged in a vertical direction, the connecting member 31 is slidably arranged in a horizontal plane, and corresponding mounting holes are arranged between adjacent counterweight members 22. The connecting member 31 is driven by the driving member 32 to be inserted into the mounting hole, thereby realizing the connection between adjacent counterweight members 22. Similarly, the connection between the connecting member 31 and the barbell bar 1 can also be realized in this way.

[0075] It should be understood that the connecting member 31 may be a latch, a sliding rod, a sliding block, etc.; the driving member 32 may be an electromagnet, a cylinder, a hydraulic cylinder, an electric push rod, etc. It is worth noting that when the driving member 32 is in the form of a cylinder, a hydraulic cylinder, an electric push rod, etc., it should be in the form of two driving ends cooperating with one connecting member 31, such as two cylinders, one cylinder drives the connecting member 31 to enter the first state, and the other cylinder drives the connecting member 31 to enter the second state.

[0076] It should be understood that a connecting hole corresponding to the connecting member 31 can be opened on the counterweight member 22, so that the connecting member 31 can be slidably inserted into the connecting hole, thereby realizing a sliding connection between the connecting member 31 and the counterweight member 22. The sliding connection between the connecting member 31 and the counterweight member 22 can also be realized through slide rails and slide grooves.

[0077] like Figure 5 As shown, in one of the embodiments, the connecting member 31 is at least partially a magnet, specifically, the side relative to the driving member 32 is a magnet, and the driving member 32 is an electromagnet, and the repulsive force and adsorption force generated by the electromagnet being energized can be used to drive the magnet to slide and insert into the fixing hole 1a and slide out of the fixing hole 1a. Specifically, when it is necessary to drive the connecting member 31 to slide and insert into the fixing hole 1a, the electromagnet is energized, and the electromagnet applies a repulsive force to the connecting member 31 made of a magnet, so that the connecting member 31 moves in a direction away from the electromagnet to slide and insert into the fixing hole 1a; when it is necessary to drive the connecting member 31 to be detached from the fixing hole 1a, a current in the opposite direction is passed to the electromagnet, and at this time, the electromagnet applies an electromagnetic attraction to the connecting member 31, so that the connecting member 31 moves in a direction close to the electromagnet, so that the connecting member 31 slides out of the fixing hole 1a.

[0078] By providing an electromagnet and controlling the direction of the current, the corresponding connecting member 31 can be controlled to be slidably inserted into the fixing hole 1 a or to slide out of the fixing hole 1 a.

[0079] It should be understood that the connecting member 31 is a permanent magnet.

[0080] like Figure 6As shown, in one embodiment, the connecting member 31 is made of ferromagnetic material, the driving member 32 is an electromagnet, and electromagnets are provided at both ends of the sliding direction of each connecting member 31. The connecting member 31 is energized and de-energized by the electromagnets at both ends of the connecting member 31 to control the sliding insertion of the connecting member 31 in the fixing hole 1a, or to slide out of the fixing hole 1a. Specifically, when it is necessary to control the sliding insertion of the connecting member 31 in the fixing hole 1a, the electromagnet on one side of the connecting member 31 is energized, and the energized electromagnet adsorbs the connecting member 31, so that the connecting member 31 is slidably inserted in the fixing hole 1a. At this time, the connection between the counterweight 22 and the barbell bar 1 is realized through the connecting member 31. When it is necessary to control the connecting member 31 to be separated from the barbell bar 1, the electromagnet on one side of the connecting member 31 is de-energized, and the electromagnet on the other side of the connecting member 31 is energized, and the energized electromagnet adsorbs the connecting member 31, so that the connecting member 31 slides out of the fixing hole 1a. At this time, the counterweight 22 is separated from the barbell bar 1.

[0081] It should be understood that the ferromagnetic material may be any one or more combinations of iron, cobalt, and nickel.

[0082] like Figure 7 As shown, in one of the embodiments, the connecting member 31 is an electromagnetic adsorption member, which can electromagnetically adsorb the barbell bar 1 or the counterweight 22 when powered on; the driving member 32 is a power supply structure, and the number of driving members 32 is multiple, and the multiple driving members 32 correspond to the multiple connecting members 31, and the driving member 32 can power on or off the corresponding connecting members 31.

[0083] Specifically, when multiple counterweights 22 are distributed in the vertical direction, the connecting member 31 is set as an electromagnetic adsorption member. By powering on or off the power supply structure, the electromagnetic adsorption member can be controlled to form or lose electromagnetic attraction. When the power supply structure is powered on, the power supply structure powers on the corresponding electromagnetic adsorption member, and the electromagnetic adsorption member forms attraction to adsorb adjacent counterweights 22 or barbell bar 1 through electromagnetic attraction. When the power supply structure is powered off, the electromagnetic adsorption member loses the electromagnetic attraction, and the adjacent counterweights 22 are disconnected, and the counterweights 22 and the barbell bar 1 are disconnected.

[0084] It should be understood that the electromagnetic adsorption component of the connecting member 31 is an electromagnetic coil, which generates electromagnetic attraction when energized.

[0085] It should be understood that the power supply structure may be an electric contact 322 and a pantograph, etc. The electric contact 322 and the pantograph can supply power to the electromagnetic coil.

[0086] like Fig. 9As shown, in one embodiment, the power supply structure includes a fixed bar 321 and a plurality of contacts 322. The fixed bar 321 is arranged in the vertical direction and connected to the barbell bar 1. The contacts 322 are arranged in a one-to-one correspondence with the connecting member 31. The contacts 322 are connected to the fixed bar 321 and can slide against the connecting member 31. Each contact 322 has a corresponding power line (not shown in the figure), and different power lines are insulated.

[0087] Specifically, when the counterweight 22 needs to be connected to the barbell bar 1, the control part contact 322 is energized, and the contact 322 supplies power to the electromagnetic adsorption component, so that the electromagnetic adsorption component forms an electromagnetic attraction to adsorb the adjacent counterweight 22 or barbell bar 1.

[0088] It should be understood that the counterweight 22 and the barbell bar 1 are made of ferromagnetic material, so that when the electromagnetic adsorption component is energized, the electromagnetic adsorption component can adsorb the adjacent counterweight 22 or barbell bar 1; the electromagnetic adsorption component fixed to the counterweight 22 and the counterweight 22 are provided with magnetic isolation material (not shown in the figure) to prevent the electromagnetic magnetic force formed by the electromagnetic adsorption component from being transmitted downward through the counterweight 22 and adsorbing the counterweight 22 below.

[0089] like Figure 4 and Fig. 9 As shown, in one embodiment, among the multiple weight pieces 22, there are at least one basic weight piece and multiple standard weight pieces, and the weight of the standard weight piece is less than that of the basic weight piece; the driving member 32 can drive the basic weight piece and the multiple standard weight pieces to be connected to or disconnected from the barbell bar 1 respectively.

[0090] Specifically, by dividing the weight pieces 22 into basic weight pieces and standard weight pieces, before the user exercises, the basic weight pieces are connected to the barbell bar 1 via the connecting piece 31, and the standard weight pieces can be selectively installed according to the weight required by the user. The existence of the basic weight pieces can reduce the weight of the required standard weight pieces.

[0091] It should be understood that the weight of the basic counterweight can be 5 kg, 10 kg, 15 kg, 20 kg, etc.; the weight of the standard counterweight can be 0.5 kg, 1 kg and 2 kg, etc. It can be seen that the weight of the standard counterweight is less than the basic counterweight.

[0092] like Fig.10 As shown, in one embodiment, multiple counterweights 22 are stacked in sequence along the vertical direction; multiple connecting members 31 are respectively connected to the multiple counterweights 22, and the connecting member 31 located at one end of the multiple counterweights 22 can be connected to or disconnected from the barbell bar 1 under the drive of the driving member 32, and the connecting member 31 located between adjacent counterweights 22 can be connected to or disconnected from the adjacent counterweights 22 under the drive of the driving member 32.

[0093] Specifically, before exercising, the user determines the required counterweight weight, drives the connecting member 31 to connect the corresponding number of counterweight members 22 through the driving member 32, and connects the counterweight members 22 to the barbell bar 1 through the connecting member 31, so that the counterweight members 22 of the set weight are fixed to the barbell bar 1, and then the barbell training can be started. During the training process, the counterweight members 22 are firmly connected to the barbell bar 1.

[0094] like Fig.11 As shown, further, the multiple weight pieces 22 located on one side of the barbell bar 1 can be distributed in two rows, and the two weight pieces 22 are both arranged in the vertical direction, one row can be provided with basic weight pieces, and the other row can be provided with standard weight pieces.

[0095] Specifically, through the above arrangement, by arranging a plurality of basic counterweights in one row, the configuration range of the barbell bar 1 can be changed within a relatively large range; by arranging a plurality of quasi-counterweights in another row, the counterweight can be accurately adjusted.

[0096] like Figure 3 and Figure 4 As shown, in one embodiment, a plurality of weight members 22 are distributed along the length direction of the barbell bar 1; a plurality of connecting members 31 are respectively connected to the plurality of weight members 22, and the connecting members 31 can be connected to or disconnected from the barbell bar 1 under the drive of the driving member 32.

[0097] Specifically, when the counterweight on the barbell bar 1 needs to be adjusted, the required counterweight weight is determined, and the driving member 32 drives the connecting member 31 to connect to the barbell bar 1 according to the required counterweight weight, and the counterweight member 22 of the required weight is fixed to the barbell bar 1 through the connecting member 31.

[0098] Multiple counterweights 22 are distributed along the length direction of the barbell bar 1. Compared with multiple counterweights 22 distributed along the vertical direction, there are the following advantages: when multiple counterweights 22 are distributed along the vertical direction, the counterweights 22 need to be connected in sequence along the vertical direction. If fine adjustment is required within a larger adjustment range, a large number of counterweights 22 with smaller weights need to be set. In the present embodiment, multiple counterweights 22 are distributed along the length direction of the barbell bar 1. Counterweights 22 of different weights can be set. The connecting member 31 is controlled to connect to the barbell bar 1 through the driving member 32 so that the required counterweights 22 are connected to the barbell bar 1. While fine adjustment is achieved, the number of small counterweights 22 required is small.

[0099] Furthermore, there are multiple basic counterweight pieces, and the weights of the multiple basic counterweight pieces are all greater than the standard counterweight piece.

[0100] Specifically, by setting up multiple basic counterweights, controlling the connecting member 31 through the driving member 32, so that the basic counterweights are connected to the barbell bar 1, the basic counterweights can significantly change the weight of the counterweights on the barbell bar 1. First, the counterweights are adjusted to a weight close to the required counterweight weight through multiple basic counterweights, and then multiple standard counterweights are fixed to the barbell bar 1 through the driving member 32, thereby achieving fine adjustment of the required counterweight weight and reducing the number of required standard counterweights.

[0101] Furthermore, the weight of at least part of the basic counterweight members is arranged in a stepped manner.

[0102] Specifically, by arranging the weight of some counterweights 22 in a stepped configuration, when the counterweight weight needs to be controlled to reach a preset value, the required counterweight weight can be quickly approached through the combination of the counterweights 22 in a stepped configuration, and then the set counterweight weight can be reached through the standard counterweights, thereby further optimizing the weight distribution of the counterweights 22, helping to reduce the number of standard counterweights required, and enabling a larger and wider range of counterweight combinations to be achieved.

[0103] like Figure 4 , 5 As shown in Figures 6, in one embodiment, the top of the weight member 22 has an opening 22a; the barbell bar 1 is slidably disposed in the opening 22a.

[0104] Specifically, by setting an opening 22a at the top of the counterweight 22, the barbell bar 1 can be slidably set on the counterweight 22 through the opening 22a. When the connecting member 31 passes through the counterweight 22 and is inserted into the barbell bar 1, the connecting member 31 confines the barbell bar 1 in the opening 22a of the counterweight 22. When the barbell bar 1 is lifted, it can drive the counterweight 22 to move upward.

[0105] like Figure 1 and Figure 7 As shown, in one embodiment, the barbell device further includes a support assembly 4, and the fixing member 21 is connected to the support assembly 4.

[0106] Specifically, by providing the support assembly 4, the support assembly 4 can support the barbell bar 1, the weight assembly 2, and the like.

[0107] It should be understood that the support assembly 4 may be a bracket, a reclining chair, etc., which can provide support while also enabling the user to perform bench press.

[0108] like Figure 5 and Figure 6 As shown, in one embodiment, the interior of the fixing member 21 is hollow, and a plurality of weight members 22 are slidably built into the fixing member 21; both ends of the barbell rod 1 extend into the two fixing members 21 respectively and can slide relative to the fixing members 21.

[0109] When a specific user is exercising, the counterweight 22 slides and is built into the fixing part 21. Even if the counterweight 22 falls due to an accident, the fallen counterweight 22 can be confined in the fixing part 21 to prevent the counterweight 22 from falling and injuring the user. Moreover, when the counterweight 22 is built into the fixing part 21, the connecting part 31 and the driving part 32 are also built into the fixing part 21, which can prevent the connecting part 31, the driving part 32 and the counterweight 22 from leaking out and affecting the appearance.

[0110] It is easy to understand that the electromagnet, cylinder, electric push rod, etc. in the above embodiments can be controlled by multiple control buttons, which belongs to the conventional control method in the field and will not be described here. In some more preferred embodiments, the actions of the electromagnet, cylinder, electric push rod, etc. can be controlled by touch screen or voice recognition. Specifically, Fig.10 As shown, the barbell device also includes a main control unit 5, which includes a touch screen 51, an identity authentication module 52 and a control host 53. The identity authentication module 52 is connected to the control host 53 for reading user information; the control host 53 is connected to the driving member 32, the touch screen 51 and the identity authentication module 52, and can control the connecting member 31 to connect or disconnect from the counterweight member 22 through the driving member 32; the control host 53 compares the user information read by the identity authentication module 52 with the stored preset user information. When the comparison result is unqualified, each counterweight member 22 is controlled to be connected to the barbell bar 1 through the driving member 32; when the comparison result is qualified, the control host 53 can control the driving member 32 according to the counterweight data input by the touch screen 51, and control a set number of counterweight members 22 to be connected to the barbell bar 1 through the driving member 32.

[0111] Specifically, the user first needs to authenticate the identity through the identity authentication module 52. The identity authentication module 52 can be a biometric (such as fingerprint recognition, facial recognition, etc.), password input or other forms of authentication. During the authentication, the control host 53 compares the read user information with the stored preset user information. When the comparison result is unqualified, it means that the user is unauthorized. The control host 53 controls the electromagnet to be energized, the output shaft of the cylinder to move, the output shaft of the electric push rod to move, etc. to control the action of the connecting member 31, and then connects each counterweight 22 to the barbell bar 1 through the connecting member 31. At this time, the barbell device is in a safe mode and cannot perform normal training. This helps to prevent unauthorized users from using the barbell device, thereby improving safety. When the comparison result is qualified, it means that the user has been authorized, and the control host 53 can control the driving member 32 according to the counterweight data input by the touch screen 51. The user selects or enters the required counterweight data through the touch screen 51, such as the number of counterweights 22 to be increased or decreased, the weight of the counterweights 22, etc. The control host 53 controls the movement of the connecting member 31 through the driving member 32 in the form of an electromagnet, a cylinder, an electric push rod, etc. according to the counterweight data input by the user, so that the connecting member 31 connects to a set number of counterweights 22, thereby achieving the connection of the set number of connecting members 31 with the barbell bar 1. After the user completes the adjustment of the counterweight 22, he can start barbell training.

[0112] Furthermore, the identity authentication module 52 includes at least two of a password input unit, a card recognition unit, and a biometric recognition unit.

By providing the grip portion, users of different age groups can choose to grip the grip portion with a relatively smaller diameter or the two ends of the barbell rod 1 with a relatively larger diameter according to their own conditions, so that users of different age groups can use the barbell device for exercise.

[0119] like Figure 1 and Figure 2 As shown, in one embodiment, the barbell device also includes a cushion assembly 6, which includes a cushion 61. The cushion 61 is connected to the support assembly 4 and is arranged below the barbell bar 1. The cushion 61 can be raised and lowered relative to the support assembly 4.

[0120] It should be understood that the seat cushion 61 can be raised and lowered by the lifting bracket and the hydraulic lifting lever. Specifically, one side of the seat cushion 61 is rotatably connected to the support assembly 4; the seat cushion assembly 6 also includes an arc block 62 and a latch 63, one end of the arc block 62 is connected to the seat cushion 61, and the other end can be slidably connected to the support assembly 4, the arc block 62 is coaxial with the rotation axis of the seat cushion 61, and the arc block 62 is provided with a plurality of circumferentially distributed limiting holes, and the latch 63 can be slidably inserted in the support assembly 4 and can be slidably inserted in the limiting hole.

[0121] Specifically, when the seat cushion 61 is used by users, the seat cushion 61 can be rotated by sliding the arc block 62 according to people of different heights and different arm spans, and then the arc block 62 is fixed to the support component 4 by the latch 63, so that the seat cushion 61 is fixed at different heights, which can be suitable for people of different arm spans and different heights to exercise.

[0122] It should be understood that the support assembly 4 is provided with a fixing hole opposite to the limiting hole, and the latch 63 is slidably inserted in the limiting hole and the fixing hole.
