Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and more specifically, to a magnetically controlled climbing machine. Background Technology

[0002] A climbing wall machine is an indoor fitness equipment primarily used to simulate rock climbing. The pedals are the main component; the user's alternating foot pressure on the pedals causes them to rise and fall in cycles, simulating the continuous climbing motion of rock climbing. Traditionally, climbing walls use a motor-driven resistance device to increase the resistance during the cycle, replicating the force exertion and range of motion of natural rock climbing, thus enhancing the realism of the training. However, the motor needs to run continuously to maintain the resistance; if the equipment loses power or the motor malfunctions, the resistance will fail, posing a safety hazard, and limiting the usability of this type of climbing wall machine.

The photoelectric switch includes a transmitter and a receiver arranged at intervals along the left and right direction, and the grating disk is located between the transmitter and the receiver.

[0011] In some embodiments of this application, the frame includes a main frame and a support frame arranged sequentially front to back. The main frame includes two inclined guide rails, which are arranged side-by-side and spaced apart in the left-right direction. The support frame includes two support tubes arranged side-by-side and spaced apart in the left-right direction. The two support tubes are respectively connected to the two guide rails and are used to support the device on the ground. The cover includes a front cover, a rear cover, a left cover, and a right cover. The front cover is located between the two guide rails, the rear cover is located between the two support tubes, and the left and right covers are located on opposite sides of the two support tubes in the left-right direction.

The first tube section and the second tube section are respectively connected to the guide rail, and the second tube section is used to support the ground.

The user's two feet step on the two pedals respectively and alternately press down on the pedals, which can simulate the alternating pedaling action during climbing. In this process, the transmission mechanism also converts the linear motion of the pedal relative to the frame into the rotational motion of the flywheel. The magnetic fields of the flywheel and the magnetic plate interact to generate magnetic resistance that prevents the flywheel from rotating. The presence of magnetic resistance makes the user's downward pedaling action feel resistant, thereby simulating the muscle load during climbing and ensuring the training effect. Therefore, this magnetic control system climbing machine uses the magnetic resistance between the flywheel and the magnetic plate to replace the resistance generated by the resistance device driven by the motor. It does not require power connection during use, making it suitable for more application scenarios. It can also avoid resistance failure due to power failure or motor failure, thereby reducing the safety hazards of the magnetic control system climbing machine. Attached Figure Description

[0035] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0036] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0037] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0038] Please see Figures 1 to 3 The magnetic control climbing machine provided in one embodiment of this utility model mainly includes a body 1, pedals 2, a flywheel 3, a magnetic plate 4, and a transmission mechanism 5. The body 1 includes a frame 11 and a cover 12. The cover 12 is disposed on the frame 11 and forms a receiving cavity with the frame 11. The pedals 2 are vertically and vertically disposed on the frame 11. There are two pedals 2, and the two pedals 2 are arranged at intervals in the left-right direction. The flywheel 3 is rotatably disposed in the receiving cavity. The magnetic plate 4 is located in the receiving cavity and has magnetic attraction with the flywheel 3. The transmission mechanism 5 is located in the receiving cavity and is connected to the two pedals 2 and the flywheel 3 respectively. The transmission mechanism 5 is configured to drive the other pedal 2 to rise and fall relative to the frame 11 when one pedal 2 rises and falls relative to the frame 11, and drive the flywheel 3 to rotate. The rising and falling directions of the two pedals 2 are opposite.

[0039] In this embodiment of the magnetic control system climbing machine, the cavity formed by the frame 11 and the cover 12 protects components such as the flywheel 3, magnetic plate 4, and transmission mechanism 5, reducing external interference and ensuring the normal operation of the magnetic control system climbing machine. Specifically, when one pedal 2 is pressed down, it triggers the transmission mechanism 5 to drive the other pedal 2 upward. The user's feet step on the two pedals 2 respectively and alternately press down on the pedals 2, simulating the alternating pedaling motion during climbing. During this process, the transmission mechanism 5 also converts the linear motion of the pedal 2 relative to the frame 11 into the rotational motion of the flywheel 3. The magnetic fields of the flywheel 3 and the magnetic plate 4 interact to generate magnetic resistance that prevents the flywheel 3 from rotating. The presence of magnetic resistance makes the user's downward pressing action on the pedal 2 feel resistant, thereby simulating the muscle load during climbing and ensuring the training effect. Therefore, this magnetic control system climbing machine uses the magnetic resistance between the flywheel 3 and the magnetic plate 4 to replace the resistance generated by the motor-driven resistance device. It does not require power connection during use, making it suitable for more application scenarios. It can also avoid resistance failure due to power failure or motor failure, thereby reducing the safety hazards of the magnetic control system climbing machine.

[0040] It should be noted that there is a magnetic attraction between the magnetic plate 4 and the flywheel 3. Either the magnetic plate 4 or the flywheel 3 can be a magnet, and the other can be metal; alternatively, both the magnetic plate 4 and the flywheel 3 can be magnets. In this embodiment, the flywheel 3 is metal, and the magnetic plate 4 is a magnet. Metal is less expensive than magnets, effectively saving costs. Specifically, the rotation of the flywheel 3 in the magnetic field cuts magnetic field lines, generating an induced current and a magnetic field. The magnetic field of the flywheel 3 and the magnetic field of the magnetic plate 4 interact to produce magnetic resistance. This implementation can generate stable magnetic resistance.

[0041] Please see Figure 2 and Figure 3 In a specific embodiment, the cover 12 has an air inlet 125 and an air outlet 126 connecting the receiving cavity to the outside. The flywheel 3 and the magnetic plate 4 are arranged side by side at intervals in the left-right direction. The flywheel 3 has several fan blades 31, and the fan blades 31 are located on the side of the flywheel 3 facing away from the magnetic plate 4. When the flywheel 3 rotates, the fan blades 31 on it drive the air to flow between the receiving cavity and the outside, thereby forming wind resistance that restricts the rotation of the flywheel 3. During the user's use of the magnetic control system climbing machine, they will be subjected to the dual effects of wind resistance and magnetic resistance. The combination of the two resistances can provide a richer simulated climbing experience.

[0042] Please see Figure 3 In one embodiment where the transmission mechanism 5 is connected to the two pedals 2 and the flywheel 3 respectively, the transmission mechanism 5 includes a first rotating shaft 51, a second rotating shaft 52, a reversing wheel assembly 53, a first transmission rope 54, a second transmission rope 55, and a third transmission rope 56. The first rotating shaft 51, the second rotating shaft 52, and the reversing wheel assembly 53 are rotatably mounted on the frame 11. The first rotating shaft 51 and the second rotating shaft 52 are arranged sequentially front and back and extend in the left and right direction. The reversing wheel assembly 53 is located above or below the first rotating shaft 51. One end of the first transmission rope 54 is connected to one of the pedals 2, and the other end passes through the first rotating shaft 51, the reversing wheel assembly 53, and the first rotating shaft 51 in sequence and is connected to the other pedal 2. The second transmission rope 55 passes through the reversing wheel assembly 53, and its two ends are connected to the two pedals 2 respectively. The second rotating shaft 52 and the first rotating shaft 51 are connected by the third transmission rope 56. The flywheel 3 is sleeved on the outside of the second rotating shaft 52.

[0043] Specifically, through the coordinated operation of the two pedals 2, the first rotating shaft 51, the reversing wheel group 53, the first transmission rope 54, and the second transmission rope 55, a linkage mechanism for the pedals 2 is established to ensure that one pedal 2 can rise relative to the frame 11 when the other pedal 2 is subjected to force and descends. Through the cooperation of the first transmission rope 54 and the second transmission rope 55, the stability and reliability of the reverse movement of the two pedals 2 can be ensured. On the other hand, when the pedals 2 rise and fall, the first rotating shaft 51 is driven to rotate through the first transmission rope 54. Since the first rotating shaft 51 and the second rotating shaft 52 are connected by the third transmission rope 56, and the flywheel 3 is sleeved on the second rotating shaft 52, the transmission mechanism 5 converts the linear movement of the pedals 2 relative to the frame 11 into the rotational movement of the flywheel 3.

[0044] In other embodiments, the transmission mechanism 5 may be a linkage structure.

[0045] In a specific embodiment, the reversing wheel assembly 53 includes a first reversing wheel 531 and a second reversing wheel 532 arranged sequentially from front to back. There are at least two of each first reversing wheel 531 and second reversing wheel 532. Each first reversing wheel 531 and each second reversing wheel 532 are arranged at intervals in the left-right direction. A first reversing rope passes around each second reversing wheel 532, and a second connecting rope passes around each first reversing wheel 531, thereby ensuring that the first reversing rope and the second reversing rope do not interfere with each other.

[0046] In this embodiment, a first sprocket 511, a second sprocket 512, and a third sprocket 513 are sequentially sleeved on the first rotating shaft 51 along the left-right direction, and a fourth sprocket 521 is sleeved on the second rotating shaft 52. Each sprocket has teeth. The first transmission rope 54 includes two chain segments and a steel wire rope connecting the two chain segments. The two chain segments of the first transmission rope 54 are respectively connected to the two pedals 2 and respectively mesh with the first sprocket 511 and the third sprocket 513. The steel wire rope of the first transmission rope 54 passes around the reversing pulley group 53. The second transmission rope 55 includes a steel wire rope, and both ends of the steel wire rope of the second transmission rope 55 are respectively connected to the two pedals 2 and pass around the reversing pulley group 53. The third transmission rope 56 includes a chain, and the chain of the third transmission rope 56 respectively meshes with the second sprocket 512 and the fourth sprocket 521 to drive the connection between the first rotating shaft 51 and the second rotating shaft 52. By replacing traditional friction transmission with the meshing between the chain and sprocket, the risk of slippage can be effectively reduced, thereby improving the stability and reliability of the overall structure, and featuring high transmission efficiency and low energy consumption.

[0047] In other embodiments, each transmission rope is a steel wire rope, and the transmission between each transmission rope and each rotating shaft relies on friction, which poses a risk of slippage.

[0048] Please see Figure 3 and Figure 5In a specific embodiment, a grating disk 514 is fitted onto the first rotating shaft 51, and a photoelectric switch 6 is fixed on the frame 11. The photoelectric switch 6 includes a transmitter and a receiver arranged at intervals along the left-right direction, with the grating disk 514 located between the transmitter and the receiver. When the first rotating shaft 51 rotates, it drives the grating disk 514 to rotate between the transmitter and the receiver. The receiver outputs a signal to provide feedback on information such as the frequency and speed of the rotation of the first rotating shaft 51, thereby reflecting the user's movement.

[0049] In this embodiment, the magnetic control system climbing machine also includes an electronic watch 20, which can display the user's movement data in real time.

[0050] Please see Figure 1 , Figure 2 and Figure 4 In a specific embodiment, the frame 11 includes a main frame 111 and a support frame 112 arranged sequentially from front to back. The main frame 111 includes two inclined guide rails 1111, which are arranged side-by-side and spaced apart in the left-right direction. The support frame 112 includes two support tubes 1121 arranged side-by-side and spaced apart in the left-right direction. The two support tubes 1121 are respectively connected to the two guide rails 1111 and are used for support on the ground. The cover 12 includes a front cover 121, a rear cover 122, a left cover 123, and a right cover 124. The front cover 121 is located between the two guide rails 1111, the rear cover 122 is located between the two support tubes 1121, and the left cover 123 and right cover 124 are respectively located on both sides of the two support tubes 1121 in the left-right direction. Two pedals 2 are respectively raised and lowerable on the two guide rails 1111, and the pedals 2 are located in front of the guide rails 1111.

[0051] The machine body 1 is provided with a stable and reliable structural design. Specifically, the center of gravity of the magnetic control system climbing machine is concentrated on the rear side. When the user's two feet are on the two pedals 2, the center of gravity is concentrated on the front side, which can ensure the stability and safety of the magnetic control system climbing machine during use. In addition, the pedals 2 are raised and lowered on the inclined guide rails 1111, which can simulate real climbing actions and further improve the simulated climbing experience.

[0052] In this embodiment, air inlets 125 are provided on the left shield 123 and the right shield 124, and air outlets 126 are provided on the front shield 121. The air outlets 126 can cool down the user and bring a more comfortable exercise experience.

[0053] Please see Figure 2 and Figure 4In a specific embodiment, the support tube 1121 includes a first tube section 1122 and a second tube section 1123 arranged sequentially from top to bottom, and a third tube section 1124 that is connected to the first tube section 1122 and the second tube section 1123 in an arc transition. The first tube section 1122 and the second tube section 1123 are respectively connected to the guide rail 1111, and the second tube section 1123 is used to support on the ground.

[0054] The first tube section 1122 is used to directly bear the force and transmit the dynamic load of the user's movement to the third tube section 1124. The third tube section 1124 is used to transmit the load to the second tube section 1123. The second tube section 1123 transmits the load to the ground to provide static support force, thereby establishing an effective load transmission path, further improving the stability and safety of the overall structure. Moreover, the arc transition structure of the third tube section 1124 can effectively eliminate the possibility of stress concentration.

[0055] In this embodiment, the second tube 1123 extends horizontally and has a foot pad at its bottom, which can play a role in anti-slip, wear-resistant, heat insulation and shock absorption.

[0056] In a further embodiment, the third tube 1124 is provided with a movable wheel. Specifically, when it is necessary to transport the magnetic control system climbing machine, the magnetic control system climbing machine can be tilted so that the movable wheel contacts the ground. Then, the magnetic control system climbing machine can be pushed to move on the ground using the movable wheel to complete the transport of the magnetic control system climbing machine. This is more convenient and labor-saving in operation.

[0057] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the front side of the guide rail 1111 is provided with a clearance opening 1112 extending along the extension direction of the guide rail 1111. The magnetic control system climbing machine also includes a connecting rod 7 and a handle 8. The connecting rod 7 is slidably disposed in the guide rail 1111 and is connected to the handle 8 and the pedal 2 respectively through the clearance opening 1112. The handle 8 is located on the front side of the guide rail 1111 and above the pedal 2. The pedal 2 is connected to the transmission mechanism 5 through the connecting rod 7.

[0058] The handle 8 and pedal 2 rise and fall synchronously through the sliding of the connecting rod 7 within the guide rail 1111. The clearance port 1112 also serves to limit the range of motion. The handle 8 allows the user's hands to grip it during exercise, which can achieve the effect of upper limb training on the one hand, and increase safety during exercise on the other.

[0059] Please see Figure 4In a specific embodiment, the connecting rod 7 includes a rod body 71, a roller assembly 72, and a pulley assembly 73. The roller assembly 72 includes two rollers 721 rotatably mounted on the rod body 71. The two rollers 721 are located on the left and right sides of the rod body 71, respectively, and are configured to roll on the front and / or rear sides of the guide rail 1111. The pulley assembly 73 includes at least two pulleys 73 rotatably mounted on the rod body 71. Each pulley 73 is spaced apart along the extension direction of the rod body 71 and is located on the left or right side of the rod body 71. The pulleys 73 are configured to slide on the left or right side of the guide rail 1111.

[0060] By setting up roller assembly 72 and pulley assembly 73, the traditional frictional contact is transformed into rolling contact on the front and rear sides and sliding contact on the left and right sides, thereby reducing the coefficient of friction, improving the smoothness of the sliding of the connecting rod 7 in the guide rail 1111, reducing the wear of the guide rail 1111, and thus improving the overall service life of the magnetic control system climbing machine.

[0061] Please see Figure 2 and Figure 3 In a specific embodiment, the frame 11 further includes a flywheel support frame 113, which is disposed in the receiving cavity and connected to the support frame 112. The flywheel 3 and the magnetic plate 4 are rotatably disposed on the flywheel support frame 113. The flywheel 3 is rotatably connected to the flywheel support frame 113 through a second rotating shaft 52. The flywheel support frame 113 is provided with a fixed shaft, and the rotating tube connected to the magnetic plate 4 is rotatably sleeved on the fixed shaft so that the magnetic plate 4 can rotate relative to the flywheel support frame 113. The magnetic control system climbing machine also includes a magnetic plate connector 9 and a cable holder 10. The magnetic plate connector 9 is connected to the magnetic plate 4, and the cable holder 10 is mounted on the flywheel support frame 113. Both the magnetic plate connector 9 and the cable holder 10 have through holes for the cable to pass through. A spring is fixed between the magnetic plate connector 9 and the cable holder 10. One end of the cable is connected to the magnetic plate connector 9, and the other end passes through the through hole of the magnetic plate connector 9, the spring, and the through hole of the cable holder 10 in sequence, and extends out of the receiving cavity. In this embodiment, the spring is mounted on the spring sleeve 91 of the magnetic plate connector 9.

[0062] Pulling the cable causes the magnetic plate 4 to rotate relative to the flywheel 3, strengthening or weakening the interaction between the magnetic plate 4 and the flywheel 3 to change the magnitude of the magnetic resistance, thus achieving adjustable magnetic resistance. During this process, the spring accumulates the elastic force that drives the magnetic plate 4 to reset, without the need for additional adjustment.

[0063] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
