The surface of the anti-slip gasket 121 can be provided with anti-slip lines as a buffer and anti-slip structure, so that the outer wall of the support rod is prevented from colliding with the surface of the support slider 12 when the support slider 12 directly contacts the support rod, and the front and rear magnets are prevented from being damaged.
In order to assist in suspending and fixing the barbell body 3 on the support bar 2, a plurality of support arms 21 are further uniformly arranged on the support bar 2 and are transversely arranged as shown in fig. 3. In cooperation with the support arm 21, a fixing hook 31 having a bent portion with an inner diameter not smaller than the outer diameter of the support arm 21 may be further installed on the barbell main body 3 inside the support slider. When barbell body 3 is hung and fixed, barbell body 3 is turned forward, fixing hook 31 is tilted forward as barbell body 3 is turned, and the inner side surface of its bent portion is overlapped above support arm 21;
in order to assist the fixing hook 31 to lap the support arm 21 as soon as possible to fix the barbell main body, a strong electromagnet can be further embedded at the position where the upper part of the support arm 21 is connected with the fixing hook 31, and the magnetic field direction of the strong electromagnet can be set to be consistent with the positive magnetic field direction of the drive coil 22 in the support rod;
the inboard position of connecting support arm 21 of fixed couple 31 still inlays and is equipped with neodymium iron boron magnet, and neodymium iron boron magnet has stronger magnetism, consequently can respond to the magnetic field of powerful electromagnetic in the support arm rapidly, by the support arm 21 on powerful electromagnetic attract and supplementary drive barbell main part 3 rotate the overlap joint in the top of support arm 21 forward. The contact position between the fixing hook 31 and the supporting arm 21 can be further provided with a rubber bushing to serve as a buffer when the fixing hook 31 and the supporting arm 21 are contacted with each other.
Specifically, the powerful electromagnet embedded in the support arm 21 may specifically include:
a magnetic core, the magnetic pole direction of which is consistent with the positive magnetic field direction of the driving coil 22, and the arrangement direction of the magnetic core is parallel to the central axis direction of the driving coil 22;
the support arm coils are uniformly wound on the magnetic core in a single direction and are connected in parallel with the adjacent drive coils 22 at the height positions of the support arms 21 through circuit connecting wires, generally, the drive coils 22 can be set into elliptical coils by matching with the lengths of the support rods, the inner sides of the long axes of the elliptical coils correspond to a plurality of support arms 21, the support arm coils in the support arms are respectively connected in parallel with the drive coils 22, and a magnetic field parallel to the magnetic field direction of the elliptical coils can be generated;
when the driving coil 22 is driven by the driving current output by the driving control unit 4 to generate a forward magnetic field correspondingly, each support arm coil on the inner side of the elliptical driving coil is synchronously driven by the driving current, so that the support arm coils and the forward magnetic field of the driving coil 22 act together, the support arm coils are synchronously driven by the driving current in the same direction to enhance the magnetism of the strong electromagnet on the support arm 21, provide upward attraction force for the barbell main body and generate a forward attraction force component for the barbell main body, the forward attraction force component can act on the neodymium iron boron magnet on the inner side of the fixed hook 31, and can assist the attraction fixed hook 31 to turn forward and lap and hang on the support arm;
when the driving coil 22 is driven by the driving current output by the driving control unit 4 to generate a reverse magnetic field, the supporting arm coils are driven by the driving current in the same direction synchronously to reduce the magnetism of the strong electromagnet on the supporting arm 21, reduce the attraction to the ndfeb magnet inside the fixed hook 31, and reduce the attraction to drive the barbell body 3 to rotate forwards to overlap the supporting arm 21.
When the driving coil 22 is driven by the driving current outputted from the driving control unit 4 to generate a forward magnetic field, the user always holds the barbell main body during the normal training process, and therefore, in the holding state during the normal training process, the fixing hook on the barbell main body does not directly turn over and abut against the support arm due to the magnetic attraction of the support arm coil, thereby preventing the barbell main body from moving up and down.
When a user takes off force, the barbell slides down, induced current is generated inside the drive coil because the magnetic field of the magnet inside the support slider is cut by the drive coil to generate a magnetic induction line, therefore, the induced current interferes with the drive current of normal work and influences the magnitude of the actual drive current inside the coil, the drive control unit monitors the drive current inside the coil in real time through the current detection unit, the actual current is compared with the current output by the drive control unit in real time, the abnormal movement of the barbell body can be found rapidly, the drive current of the drive coil and the support arm coil is switched rapidly, the forward magnetic field is enhanced to prevent the barbell body from falling down in an accelerated manner, meanwhile, the hook is fixed by strong magnetic attraction of the support arm coil, and the barbell body is automatically rotated forwards and hung on the support arm.
The support arms 21 may be arranged to be uniformly arranged on the inner side surface of the support bar 2 in the axial direction of the support bar 2. Each driving coil in the supporting rod 2 corresponds to a plurality of supporting arms within the height range of the driving coil, and each group of driving coils 22 is connected with a plurality of supporting arm coils within the same height range of the driving coil in parallel. When the barbell main body slides down, the driving coil is driven by the driving control unit to quickly generate a positive magnetic field with maximum intensity, at the moment, the supporting arm coils on the inner side of the driving coil are simultaneously triggered to generate large driving current, and the auxiliary fixing hook rotates forwards to be suspended on any one supporting arm.
In the support arm, the arrangement direction of the magnetic core and the axial direction of the drive coil 22 may be set to be parallel to each other, and the support arm coil is wound around the outer periphery of the magnetic core uniformly in the same direction as the drive coil 22.
From this, the frame of squatting deeply of this application accessible following mode operation:
in the initial state, the barbell body is suspended on the support arm 21 by the fixing hook 31;
when the user is training normally:
the user stands under the barbell main part earlier, holds the barbell main part, puts it in the trapezius position, then stands up with exerting oneself, lifts the barbell main part to the high position of cooperation in its height. In the process of lifting the barbell main body, the supporting slide blocks connected to the barbell main body synchronously move upwards, the driving coils on the upper part of the supporting rod correspondingly cut the magnetic induction lines of the supporting slide blocks to generate induction currents, the induction currents are monitored in real time by the current detection units connected with the driving coils and uploaded to the driving control unit 4, the driving control unit 4 determines the driving coil L at the highest position generating the induction currents according to current signals uploaded by the current detection units, and according to the set height L of the driving coil L, the range of resistance matched with the height of a user is determined to be L0.3-Z-0.3 and the range of assistance X-0.3;
therefore, when a user drives the barbell main body to squat, the drive control unit 4 judges induced current according to the difference between the actual current of each drive coil and the drive current thereof, determines the current position of the barbell main body, does not output any drive current when the barbell main body is in a resistance range l x 0.3 and Z which is not less than l, and provides training intensity by the weight of the barbell main body; when the barbell main body is in the assistance range of 0 to l X0.3, positive driving current is output, upward assistance is provided for the barbell main body by utilizing the magnetic action of a positive magnetic field of the driving coil on the supporting slide block, the downward pressure of the barbell on a user is reduced, and the user is prevented from losing power in the range.
When a user drives the barbell main body to stand up, the drive control unit 4 judges induced current according to the difference value between the actual current of each drive coil and the drive current of the drive coil, determines the current position of the barbell main body, outputs forward drive current when the barbell main body is in the power-assisted range of 0 to 0.3, provides upward power assistance for the barbell main body by utilizing the magnetic action of a forward magnetic field of the drive coils on the support sliding block, and assists the user to drive the barbell main body 3 to slide upwards; when the barbell main body continues to move upwards to a resistance range l x 0.3 and Z are not less than l, outputting reverse driving current, providing downward additional resistance to the barbell main body by utilizing the magnetic action of a reverse magnetic field of a driving coil on a supporting slide block, increasing the additional resistance on the basis of the self weight of the barbell main body, and increasing the training intensity so as to further improve the training effect;
after the drive control unit 4 determines the current height position of the barbell body 3 in response to the induced current of each drive coil 22 and/or support arm coil during the process of the user driving the barbell body 3 to slide up or down, the drive coils 22 and/or support arm coils matching the current height position of the barbell body 3 can be driven to generate corresponding magnetic fields only according to the current user state. At this time, each driving current can be set to be lower than the maximum limit value of the current that can be output by the driving control unit 4, so that the fixing hook can be prevented from being influenced by the overlarge magnetic force of the support arm coil, and the movement of the barbell main body can be prevented from being hindered.
In any state, once the drive control unit 4 determines the induced current according to the difference between the actual current of each drive coil and the drive current thereof, when detecting that the current moving direction of the barbell body is changed from the original normal upward movement to the downward falling in the process of the user driving the barbell body to stand up, or when detecting that the current moving direction of the barbell body is the downward movement and the accelerated falling in the process of the user driving the barbell body to squat, an emergency protection mechanism is triggered:
