Description
Technical Field
[0001] This application belongs to the field of fitness equipment technology, and in particular relates to a folding training device. Background Technology
[0002] As fitness awareness becomes more widespread, people are starting to buy fitness equipment for their homes so they can exercise at home.
[0003] Existing training devices include a main frame, a base plate, and a resistance source assembly. The resistance source assembly is located on the main frame, and to ensure the stability of the main frame, it is usually fixedly mounted on the base plate. However, this fixed structure occupies a lot of space. In contrast, existing folding training devices designed to save space typically hinge the base plate to the main frame to achieve storage.
[0004] However, in existing folding training devices, the connection between the base plate and the main frame is not stable enough due to the rotational connection. When athletes perform exercises by pulling the resistance source components through the main frame, the main frame and the base plate tend to move relative to each other. When the connection is subjected to excessive force, the main frame is at risk of tipping over to the base plate. Summary of the Invention
[0005] To address the shortcomings of related technologies, this application provides a folding training device that uses the locking angle between the first and second slide rods to lock the sliding pin inserted into the pin hole, preventing the sliding pin from sliding out of the pin hole during movement, thereby ensuring the stability of the connection between the main frame and the base plate.

[0056] Reference Appendix Figures 1 to 9This application provides a folding training device, including a main frame 1, a control housing 29, a base plate 18, a control motor 25, a sliding pin 19, a first slide rod 20, and a second slide rod 21; wherein, the main frame 1 extends in any direction, the direction of extension being the length direction of the main frame 1; the control housing 29 is fixedly mounted on one end of the main frame 1, and a resistance source assembly is provided inside the control housing 29; one end of the base plate 18 is rotatably connected to one end of the control housing 29, and a pin hole is provided on the base plate 18; the control motor 25 is located inside the control housing 29, and the control motor 25 includes an actuating end; the sliding pin 19 slides through the side wall of the control housing 29, and the sliding pin 19 is used to extend out of the control housing 29 and into the pin hole to limit the relative rotation between the base plate 18 and the control housing 29; or The sliding pin 19 extends out of the pin hole to release the relative rotation restriction between the base plate 18 and the control box 29; the first slide rod 20 is located inside the control box 29, with one end rotatably connected to the sliding pin 19 and the other end rotatably connected to the actuating end; the second slide rod 21 is located inside the control box 29, with one end rotatably connected to the inner wall of the control box 29 and the other end rotatably connected to the first slide rod 20 and the rotating end; the actuating end of the control motor 25 drives the first slide rod 20 and the second slide rod 21 to move, and the included angle formed between the first slide rod 20 and the second slide rod 21 gradually increases until the included angle is greater than a straight angle. At this time, the first slide rod 20 and the second slide rod 21 form a negative angle lock, and the sliding pin 19 is located inside the pin hole.
[0057] Reference Appendix Figure 1 In some embodiments, the main frame 1 is a rectangular frame component, and the main frame 1 extends in any direction, with the direction of extension being the length direction of the main frame 1; in some embodiments, the main frame 1 is disposed on a horizontal plane, and the length direction of the main frame 1 is perpendicular to the horizontal plane.
[0058] Reference Appendix Figures 1 to 4 In some embodiments, the control housing 29 is fixed to one end of the main frame 1, and the control housing 29 is provided with a resistance source assembly.
[0059] Reference Appendix Figures 2 to 3 In some embodiments, the sliding pin 19 is slidably disposed on the side wall of the control box 29. The sliding pin 19 is used to extend out of the control box 29 and into the pin hole to restrict the relative rotation between the base plate 18 and the control box 29; or the sliding pin 19 is used to extend out of the pin hole to release the restriction on the relative rotation between the base plate 18 and the control box 29.
[0060] Reference Appendix Figures 2 to 3In some embodiments, the control motor 25 is located inside the control housing 29. The control motor 25 includes an actuating end and a first slide rod 20 located inside the control housing 29. One end of the first slide rod 20 is rotatably connected to the sliding pin 19, and the other end is rotatably connected to the actuating end. The first slide rod 20 is used to transmit the power of the actuating end to the sliding pin 19, thereby driving the sliding pin 19 to extend into or out of the pin hole. The second slide rod 21 is located inside the control housing 29. One end of the second slide rod 21 is rotatably connected to the inner wall of the control housing 29, and the other end is rotatably connected to the first slide rod 20 and the actuating end. The second slide rod 21 is used to assist the first slide rod 20 in pushing or pulling the sliding pin 19, and is used to cooperate with the first slide rod 20 to support the sliding pin 19 to stably extend into the pin hole.
[0061] Reference Appendix Figures 2 to 3 In some embodiments, the actuating end of the control box 29 is connected to a linkage 22, and the actuating end is used to drive the linkage 22 to perform linear reciprocating motion; a limiting groove 24 is provided on the linkage 22, the limiting groove 24 is a long groove, and the limiting member 23 is slidably disposed in the limiting groove 24, and the limiting member 23 is rotatably connected to the connection between the first slide rod 20 and the second slide rod 21; when the sliding pin 19 moves from a state not inserted into the pin hole to a state inserted into the pin hole, the limiting member 23 slides from one end of the limiting groove 24 to the other end.
[0062] The linkage 22 and the limiting member 23 work together to control the movement of the first slide rod 20 and the second slide rod 21 while the linkage 22 is moving linearly and reciprocating with the actuator end, thereby forming a preset angle to limit the relative rotation of the control box 29 and the base plate 18.
[0063] It should be noted that the number of pin holes, sliding pins 19, first slide rods 20, second slide rods 21, limiting grooves 24, and limiting members 23 should be set in multiples according to the actual situation to strengthen the relative stability between the base plate 18 and the control box 29 and the main frame 1. In a preferred embodiment, a linkage member 22 is provided with three limiting grooves 24, and three limiting members 23 are respectively provided in the three limiting grooves 24. The three first slide rods 20 and the three second slide rods 21 are provided in the control box 29. The three first slide rods 20 are rotatably connected to the three sliding pins 19. When the control motor 25 drives the linkage member 22 to move, the linkage member 22 simultaneously pushes out the three sliding pins 19 and inserts them into the three pin holes.
[0064] Reference Appendix Figures 2 to 3 In some embodiments, when the sliding pin 19 is not inserted into the pin hole, a free angle is formed between the first slide rod 20 and the second slide rod 21, and the opening of the free angle faces the side closer to the actuating end; when the sliding pin 19 is inserted into the pin hole, a locking angle is formed between the first slide rod 20 and the second slide rod 21, and the opening of the locking angle faces the side farther from the actuating end; the locking angle is greater than the free angle.
[0065] When the sliding pin 19 is not inserted into the pin hole, a free angle is formed between the first slide rod 20 and the second slide rod 21. When the control motor 25 drives the linkage 22 to move, the linkage 22 moves towards the actuating end, and the included angle between the first slide rod 20 and the second slide rod 21 gradually increases. When the included angle is equal to a flat angle, the axial directions of the first slide rod 20 and the second slide rod 21 are consistent. At this time, the sliding pin 19 slides to the deepest part of the pin hole. When the control motor 25 drives the linkage 22 to continue moving, the included angle increases to a value greater than a flat angle to form a locking angle. The sliding pin 19 retracts but does not extend out of the pin hole. After the dead angle is formed, the sliding pin 19 is located in the pin hole.
[0066] It should be noted that the locking angle is greater than the free angle, which is used to ensure that the sliding pin 19 retracts but does not extend out of the pin hole. In some embodiments, the locking angle is 181° to 185°, which is used to reduce the retraction stroke of the sliding pin 19 and ensure that the contact area between the sliding pin 19 and the pin hole is large enough to limit the relative rotation between the control chassis 29 and the base plate 18.
[0067] It should be noted that in some embodiments, the value range of the free angle is greater than 0° and not greater than 160°. When there is enough space inside the control box 29, the smaller the angle of the free angle, the greater the stroke of the sliding pin 19, the greater the contact area between the sliding pin 19 and the pin hole, and the more stable the connection between the control box 29 and the base plate 18. The specific value of the free angle depends on the actual situation.
[0068] Reference Appendix Figures 2 to 3 In some embodiments, the locking member 26 is fixed inside the control box 29 and is located on one side of the linkage member 22; after the sliding pin 19 extends into the pin hole, the linkage member 22 abuts against the locking member 26.
[0069] During the athlete's movement, in order to limit the relative rotation between the control box 29 and the base plate 18, most of the force is the shear force on the sliding pin 19, and a small part of the force pushes the sliding pin 19 into the control box 29. When the pushing force is transmitted to the first slide rod 20 and the second slide rod 21 through the sliding pin 19, the dead angle tends to decrease, thereby pushing the linkage 22 to move closer to the actuator. This may cause the actuator to be damaged due to excessive force. The fixed setting of the locking member 26 resists the pushing force of the linkage 22, thereby preventing the actuator from being stressed, extending the life of the control motor 25, and making the dead angle stably support the sliding pin 19.
[0070] Reference Appendix Figures 2 to 3In some embodiments, two sensors 27 are respectively disposed on the control housing 29 and the base plate 18, and the two sensors 27 are electrically connected to the controller of the control motor 25. When in the retracted state, the sensors 27 on the control housing 29 and the base plate 18 are not connected. When the control housing 29 and the base plate 18 are rotated relative to each other to the unfolded state perpendicular to each other, the sensors 27 on the control housing 29 and the base plate 18 are connected to drive the control motor 25 to start, thereby causing the sliding pin 19 to extend into the pin hole.
[0071] Reference Appendix Figures 1 to 4 In some embodiments, a switch 28 is provided at the end of the base plate 18 away from the main frame 1. The two sensors 27 are magnetic induction sensors. The switch 28 is connected to the sensor 27 on the base plate. When the athlete presses the switch 28, the switch 28 pulls the sensor 27 on the base plate 18 away from the control box 29, so as to disconnect the connection of the two sensors 27, thereby driving the control motor 25 to start, so as to extend the sliding pin 19 out of the pin hole.
[0072] Reference Appendix Figures 4 to 6 In some embodiments, two rotating frames 2 are disposed opposite to each other at both ends of the main frame 1. The rotating frame 2 is a cylindrical component with closed ends. The rotating frame 2 and the main frame 1 are rotatably connected by a first rotating shaft. The axis of the first rotating shaft of the rotating frame 2 is parallel to the length of the main frame 1, so that when the rotating frame 2 rotates relative to the main frame 1, it can drive the swing arm 5 to rotate relative to the main frame 1, thereby adjusting the two swing arms 5 away from the main frame 1 to move away from each other or closer to each other.
[0073] Reference Appendix Figure 6 , Figure 7 In some embodiments, the end of the rotating frame 2 away from the horizontal plane and the end of the main frame 1 away from the horizontal plane are provided with corresponding first insertion holes 6. The first insertion holes 6 are arranged around the first rotating shaft. A first pin 7 is slidably provided in the first insertion hole 6. The first pin 7 and the first insertion hole 6 are used to cooperate to control the relative rotation of the main frame 1 and the rotating frame 2, so that the main frame 1 and the rotating frame 2 are relatively released or relatively locked.
[0074] Reference Appendix Figure 8 In some embodiments, the outer wall of the main frame 1 is also provided with a first switch 8. The first switch 8 is located on one side of the first pin 7 and is connected to it by a cable. By pressing or releasing the first switch 8, the first pin 7 is controlled to extend into or out of the first insertion hole 6 on the main frame 1 and the rotating frame 2, thereby facilitating the adjustment of the relative rotation of the main frame 1 and the rotating frame 2.
[0075] Reference Appendix Figure 6 , Figure 7In some embodiments, the sliding assembly is disposed within the rotating frame 2. The sliding assembly includes a sliding member 3 and a sliding frame 4. The sliding frame 4 is fixedly disposed within the rotating frame 2 and extends along the length direction of the main frame 1. The sliding member 3 is slidably disposed on the sliding frame 4 and slides relative to the rotating frame 2 along the length direction of the main frame 1 to adjust the distance of the swing arm 5 on the main frame 1 relative to the horizontal plane, i.e., the height of the swing arm 5.
[0076] Reference Appendix Figure 7 , Figure 8 In some embodiments, the sliding frame 4 and the sliding member 3 are respectively provided with corresponding second insertion holes 9, and a second pin 10 is slidably provided in the second insertion hole 9. The second pin 10 and the second insertion hole 9 are used to cooperate to control the relative sliding of the sliding frame 4 and the sliding member 3, so that the sliding member 3 and the sliding frame 4 are relatively released or relatively locked.
[0077] In some embodiments, the swing arm 5 is rotatably mounted on the sliding member 3 via a second rotating shaft. The axis of the second rotating shaft of the swing arm 5 is perpendicular to the axis of the first rotating shaft of the rotating frame 2, and is used to adjust the angle between the swing arm 5 and the main frame 1.
[0078] Reference Appendix Figure 9 In some embodiments, the outer wall of the swing arm 5 is also provided with a second switch 11 and a third switch 14; wherein the third switch 14 is connected to the second pin 10 by cable, and by toggling the third switch 14, the second pin 10 is controlled to extend into or out of the second insertion hole 9 on the sliding member 3 and the sliding frame 4, thereby facilitating the restriction or release of the relative sliding of the sliding member 3 and the sliding frame 4.
[0079] Reference Appendix Figure 8 In some embodiments, the slider 3 is provided with a plurality of slots 12 around the second rotating shaft, and the end of the swing arm 5 near the slider 3 is provided with a groove 13. A positioning member is slidably provided in the groove 13. The positioning member is used to extend into or out of the slot 12 to control the relative position of the swing arm 5 and the slider 3, thereby achieving the purpose of adjusting the included angle between the swing arm 5 and the rotating frame 2.
[0080] The second switch 11 is connected to the positioning member cable. By pressing or releasing the second switch 11, the positioning member can be controlled to extend into or out of the slot 12, thereby facilitating the restriction or release of the relative rotation between the sliding member 3 and the swing arm 5.
[0081] In some embodiments, the resistance source assembly includes a resistance motor and a pulley system. The resistance motor includes an output end and an input end. The resistance source assembly is located inside the main frame 1. The transmission component includes, but is not limited to, a pull rope and a steel cable. The transmission component passes through the swing arm 5. One end of the transmission component extends into the main frame 1 and is connected to the output end of the resistance motor through the pulley system. The other end extends out of the swing arm 5 and is used to connect with a handle component. The handle component is used to facilitate the trainee to grip and pull the transmission component. The handle component includes, but is not limited to, a pull ring, a pull rod, and a collar.
[0082] Reference Appendix Figure 1 In some embodiments, the main frame 1 is provided with a clearance opening 17, which is located between the two rotating frames 2. The clearance opening 17 is used to accommodate the storage pad 15. The storage pad 15 is rotatably located at one end of the main frame 1 near the horizontal plane. The storage pad 15 rotates relative to the main frame 1 through a third rotating shaft. When the storage pad 15 is in the stored state, it is located in the clearance opening 17. When the storage pad 15 rotates from the stored state to the unfolded state, the end of the storage pad 15 away from the main frame 1 rotates around the third rotating shaft to a position perpendicular to the length direction of the main frame 1, so that the trainee can sit on the storage pad 15 for training.
[0083] Reference Appendix Figure 1 In some embodiments, the storage mat 15 includes a seat cushion, a back cushion, a support rod, and a base frame; wherein the base frame rotates relative to the main frame 1 via a third pivot, the seat cushion and the back cushion are mounted on the base frame, the back cushion is rotatably connected to the base frame, one end of the support rod is rotatably connected to the base frame, and the other end is detachably connected to the back cushion, so that the back cushion maintains a constant angle between the back cushion and the base frame after rotating a certain angle relative to the base frame.
[0084] Reference Appendix Figure 1 , Figure 4 In some embodiments, a support frame 16 is provided on the side of the storage mat 15 near the horizontal plane. The support frame 16 is rotatably mounted on the storage mat 15 and is located at the end of the storage mat 15 away from the main frame 1. When the storage mat 15 is unfolded, the end of the storage mat 15 away from the main frame 1 is supported by the support frame 16, and the end of the storage mat 15 connected to the main frame 1 is supported by the main frame 1, so that the two ends of the storage mat 15 are stable when unfolded, making it convenient for the trainee to sit on the storage mat 15 for training.
[0085] In some embodiments, the storage pad 15 is further provided with a storage groove on the side near the horizontal plane, the storage groove being used to store the support frame 16.
[0086] In some embodiments, the storage mat 15 is also provided with two straps on both sides. The two straps are used to fix the trainee's legs. When the trainee sits on the storage mat 15 to do lat pulldown exercises, if the resistance of the resistance motor is set too high, it may cause the trainee to be pulled up through the transmission component. The two straps fix the trainee's legs to the storage mat 15 to prevent accidents from happening.
[0087] refer to Figures 1 to 3In some embodiments, one end of the base plate 18 is rotatably connected to one end of the control box 29. The base plate 18 is provided with a pin hole, and the base plate 18 can be rotated to a position parallel to the main frame 1 for storage. When the base plate 18 is unfolded, the length direction of the base plate 18 is perpendicular to the length direction of the main frame 1. After the storage pad 15 is unfolded, the storage pad 15 is mounted on the base plate 18 through the support frame 16. The base plate 18 is provided with anti-slip grooves for anti-slip.
[0088] It should be noted that, in the folding training device of this application, when in the storage state, the swing arm 5 rotates into the rotating frame 2, the storage pad 15 rotates into the clearance opening 17, the support frame 16 rotates into the storage slot, and the base plate 18 rotates to be parallel with the storage pad 15, so as to save a lot of space resources.
[0089] In actual use, the base plate 18 is rotated to a position where its length direction is perpendicular to the length direction of the main frame 1. The control box 29 is connected to the sensor 27 on the base plate 18 to drive the control motor 25 to start, so that the sliding pin 19 extends into the pin hole, and the relative position of the base plate 18 and the main frame 1 is stable. The storage pad 15 is rotated to the side of the base plate 18 away from the horizontal plane and is mounted on the base plate 18 through the support frame 16. The trainee adjusts the clamping distance of the two swing arms 5 away from the main frame 1 through the first switch 8 and the rotating frame 2, thereby adjusting the angle between the two swing arms 5.
[0090] The distance between the swing arm 5 and the horizontal plane can be adjusted by the third switch 14 to accommodate people of different heights to use the folding trainer of this application for training; the angle between the swing arm 5 and the rotating frame 2 can be adjusted by the second switch 11 to meet the needs of different trainees when performing different types of training.
[0091] The folding trainer of this application locks the sliding pin 19 inserted into the pin hole by the locking angle of the first slide rod 20 and the second slide rod 21, preventing the sliding pin 19 from sliding out of the pin hole during movement, so as to ensure the stability of the connection between the main frame 1 and the base plate 18; the cooperation between the rotating frame 2 and the main frame 1 satisfies the angle requirement between the two swing arms 5; the height of the swing arms 5 is adjusted by the sliding component; the rotational cooperation between the swing arms 5 and the sliding component 3 satisfies the angle requirement between the rotating frame 2 and the swing arms 5; the storage pad 15 is rotatably connected to the main frame 1, the base plate 18 is rotatably connected to the main frame 1, and the support frame 16 is rotatably connected to the storage pad 15, so that the folding trainer saves more space resources when stored.
[0092] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
