Description

Technical Field

[0001] This utility model relates to the technical field of magnetically controlled wheels, specifically a combined magnetically controlled wheel assembly. Background Technology

[0002] Magnetic control wheel sets are devices that use magnetic fields to achieve precise control and high efficiency. They are widely used in fitness equipment, especially in rowing machines and exercise bikes. Magnetic control wheel sets can precisely control resistance by adjusting the magnitude of the magnetic force, thereby meeting different training needs.

[0003] The existing technology has the following shortcomings: The existing technology, disclosed in CN221206664U, discloses an EMS magnetic control wheel assembly structure for an exercise bike, "including a base, an inertia wheel, a small pulley shaft, a flange seat one, left and right fixing plates one, an electromagnet, left and right fixing plates two, and a flange seat two; wherein, the inertia wheel is mounted on the small pulley shaft and driven to rotate by it; the left and right fixing plates one are located on both sides of the inertia wheel; the flange seats are mounted on the small pulley shaft and respectively installed on the left and right fixing plates one; the electromagnet is installed on the left and right fixing plates one and cooperates with the inertia wheel; the left and right fixing plates two are located on both sides of the left and right fixing plates one."

[0004] When assembling the above-mentioned magnetic control wheel assembly, multiple sets of flange seats, fixing plates and other structures are used to install and fix the magnetic control wheel assembly, which is relatively troublesome. At the same time, the magnetic control wheel and the brake wheel are set on the same spindle, so when the magnetic control wheel needs to be repaired or replaced, the whole assembly needs to be disassembled, which is also troublesome. In addition, the inner diameter of the magnetic control wheel is different from that of the other wheels, making coaxial assembly more complicated. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 As shown in this embodiment, a combined magnetic control wheel assembly includes a magnetic control wheel body 1. A through hole 2 is provided at the center of the magnetic control wheel body 1. Two sets of drive shafts 3 are symmetrically inserted through the through hole 2. An installation assembly is provided inside the drive shaft 3. The installation assembly can install and fix the drive shaft 3 and the magnetic control wheel body 1. An auxiliary wheel 4 is sleeved on the outside of the drive shaft 3. Fixing discs 5 are bolted to both sides of the auxiliary wheel 4. The fixing discs 5 are sleeved on the outside of the drive shaft 3. A first groove 6 and a second groove 7 are provided on the surface of the auxiliary wheel 4. With the first groove 6, existing hand-held cables and the like can be wound and placed. With the second groove 7, elastic strips and the like can be wound and placed. With the fixing discs 5, the auxiliary wheel 4 can be installed and fixed.

[0023] like Figure 2 and Figure 3As shown, the mounting assembly includes a cavity 8, multiple sets of limiting holes 9, multiple sets of fixing holes 10, a miniature cylinder 11, a sliding plate 12, a trapezoidal block 13, multiple sets of limiting grooves 14, a locking post 15, a clamp 16, multiple sets of fixing plates 17, and two sets of positioning wheels 18. The cavity 8 is located at the end of the drive shaft 3. The multiple sets of limiting holes 9 are symmetrically located on the surface of the drive shaft 3. The multiple sets of fixing holes 10 are located on the inner wall of the through hole 2. The miniature cylinder 11 is installed in the cavity 8, and the sliding plate 12 is installed on the miniature cylinder 11. At the output end, the trapezoidal block 13 is mounted on the side wall of the sliding plate 12, multiple sets of limiting grooves 14 are formed on the surface of the trapezoidal block 13, the locking post 15 passes through the limiting hole 9, the clamp 16 is sleeved on the outside of the drive shaft 3, multiple sets of fixing plates 17 are mounted on the side wall of the clamp 16, two sets of positioning wheels 18 are rotatably mounted on the side wall of the fixing plate 17, the sliding plate 12 is slidably disposed with the inner wall of the cavity 8, the limiting hole 9 is correspondingly disposed with the fixing hole 10, the bottom of the locking post 15 is provided with a pulley, and the locking post... The locking pin 15 is slidably disposed with the limiting groove 14. The locking pin 15 is correspondingly disposed with the limiting hole 9 and the fixing hole 10. The positioning wheel 18 is attached to the magnetic control wheel body 1. The fixing plate 17 and the positioning wheel 18 can be installed and fixed by the clamp 16. The micro cylinder 11 drives the sliding plate 12 to move. The movement of the sliding plate 12 drives the trapezoidal block 13 to move. The movement of the trapezoidal block 13 causes the locking pin 15 to move upward. Subsequently, the locking pin 15 is inserted into the fixing hole 10, completing the installation and fixing between the drive shaft 3 and the magnetic control wheel body 1. The design is relatively simple to install and assemble, facilitating the combination of wheels with different inner diameters. With the setting of the limiting groove 14 and the limiting hole 9, the vertical movement of the locking post 15 can be guaranteed. With the rotation setting of the positioning wheel 18, the positioning of the magnetic control wheel body 1 can be assisted, while avoiding affecting the subsequent rotation of the magnetic control wheel body 1. The symmetrical arrangement of the two sets of transmission shafts 3 means that when the magnetic control wheel body 1 is inspected or replaced, only the position of the transmission shaft 3 needs to be slightly moved to remove the magnetic control wheel body 1, which is convenient for users to disassemble and assemble.

[0024] This utility model provides a combined magnetically controlled wheel assembly, the specific working principle of which is as follows:

[0025] When using this combined magnetic control wheel assembly, the first groove 6 allows for the winding and placement of existing hand-operated cables, while the second groove 7 allows for the winding and placement of elastic strips. The fixed plate 5 allows for the installation and fixation of the auxiliary wheel 4. With the installation assembly, the clamp 16 allows for the installation and fixation of the fixed plate 17 and the positioning wheel 18. When installing and fixing the magnetic control wheel body 1, the side wall of the magnetic control wheel body 1 is brought into contact with the positioning wheel 18. Then, the micro cylinder 11 drives the sliding plate 12 to move. The movement of the sliding plate 12 causes the trapezoidal block 13 to move, and the movement of the trapezoidal block 13 causes the locking column to engage. As the drive shaft 15 moves upward, the locking post 15 is inserted into the fixing hole 10, completing the installation and fixing between the drive shaft 3 and the magnetic control wheel body 1. The installation and assembly are relatively simple and facilitate the combination of wheels with different inner diameters. With the setting of the limiting groove 14 and the limiting hole 9, the vertical movement of the locking post 15 can be guaranteed. With the rotation setting of the positioning wheel 18, the positioning and installation of the magnetic control wheel body 1 can be assisted, while avoiding affecting the subsequent rotation of the magnetic control wheel body 1. The symmetrical arrangement of the two sets of drive shafts 3 means that when the magnetic control wheel body 1 is inspected or replaced, only the position of the drive shaft 3 needs to be slightly moved to remove the magnetic control wheel body 1, which is convenient for the user to disassemble and assemble.
