Abstract
Description
Technical Field
[0001] This invention relates to the field of fitness, and more specifically to a fitness robotic arm with a horizontal rotation mechanism. Background Technology
[0002] Strength training equipment allows users to train multiple muscle groups, such as the pectoralis major, deltoids, abdominal muscles, and lower back muscles, by pulling the rope in different directions and setting different resistance levels. It is very popular among fitness enthusiasts.
[0003] When users perform arm strength training using the robotic arm of a strength training device, the robotic arm is often equipped with horizontal and vertical rotation mechanisms. These mechanisms control the end effector of the robotic arm to a suitable position. Limiting mechanisms are then installed to fix these mechanisms, ensuring the robotic arm is completely stationary and facilitating rope-pulling training. However, this method of using two separate limiting mechanisms for horizontal and vertical rotation requires users to adjust each mechanism using two separate switches. This is cumbersome, increases the difficulty of use, and negatively impacts the user experience. Furthermore, users often struggle to achieve the correct position with a single adjustment, as they may not be able to do so effectively.
[0004] In view of this, this application proposes a fitness robotic arm with a horizontal rotation mechanism. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a fitness robotic arm with a horizontal rotation mechanism.
[0006] To solve the above technical problems, the following technical solution is adopted: A fitness robotic arm with a horizontal rotation mechanism includes a body and a horizontal rotation mechanism. The body has a horizontal rotation mechanism, which includes a stator and a central spindle. The stator and the central spindle form a limiting groove.
[0007] The main body also has an adjustment mechanism, which includes a sliding member, a reset member, and a horizontal limiting member.
[0008] The sliding member is provided with a reset member, and the sliding member is connected to a horizontal limiting member, which is connected to the horizontal rotation mechanism.
[0009] Furthermore, the horizontal rotation mechanism also includes a first bearing housing and a second bearing housing, the first bearing housing being installed on the inner end of the central spindle and the second bearing housing being installed on the outer end of the central spindle.
[0010] Furthermore, the reset component is an electromagnetic clutch device, a magnetic attraction device, a spring with elastic reset function, a rubber component, or a silicone component.
[0011] Furthermore, the sliding member is provided with a support surface for mounting the reset member, and one end of the reset member abuts against the support surface.
[0012] Furthermore, the horizontal limiting component is a limiting steel ball disposed on the inner side of the sliding component, and the limiting steel ball matches the limiting groove.
[0013] Furthermore, the slider has a first sliding surface, a second sliding surface, and a guide surface disposed between the first sliding surface and the second sliding surface.
[0014] When there is no external force acting on the slider, the first sliding surface of the slider is in contact with the limiting steel ball.
[0015] When an external force drives the slider to move, the guide surface of the slider comes into contact with the limiting steel ball, causing the limiting steel ball to disengage from the limiting groove; after the limiting steel ball completely disengages from the limiting groove, the second sliding surface of the slider comes into contact with the limiting steel ball.
[0016] Furthermore, the adjustment mechanism also includes a vertical limiting member, which is disposed on the side of the sliding member and is connected to a vertical rotation mechanism.
[0017] Furthermore, the sliding member is connected to a driving device, and the external force generated by the driving device is used to drive the sliding member to move, so that the horizontal limiting member disengages from the horizontal rotation mechanism and the vertical limiting member disengages from the vertical rotation mechanism.
[0018] Furthermore, the drive device is connected to a clutch device, which is used to keep the drive device and the sliding member in two states: connected and disconnected.
[0019] Furthermore, the sliding member is connected to a pull rope connector, the pull rope connector is connected to a pull rope, the pull rope is connected to a pull rope switch, and the pull rope switch is disposed on the outer wall of the main body.
[0020] The above technical solution has the following beneficial effects: This invention relates to a fitness robotic arm with a horizontal rotation mechanism. The robotic arm incorporates an adjustment mechanism and a horizontal rotation mechanism, with the adjustment mechanism allowing for limit adjustment of the horizontal rotation mechanism. By including a sliding member, a reset member, and a horizontal limit member, when the sliding member is not under external force, the horizontal limit member locks the horizontal rotation mechanism under the action of the reset member, thus locking the robotic arm for convenient rope-pulling training. When the user needs to adjust the position of the robotic arm, the user controls a drive device via a switch, which generates an external force that moves the sliding member, causing the horizontal limit member to disengage from the horizontal rotation mechanism. This allows the user to control the switch with one hand and pull the robotic arm with the other to adjust its position conveniently. If the switch is released, the sliding member returns to a state of no external force, and the horizontal limit member locks the horizontal rotation mechanism again under the action of the reset member, thus re-locking the horizontal rotation mechanism for convenient rope-pulling training.
[0021] Based on the above structure, the adjustment mechanism can also be equipped with a vertical limiting member, which is located on the side of the sliding member and connected to the vertical rotation mechanism. When the adjustment mechanism adjusts the horizontal rotation mechanism, the vertical rotation mechanism can be adjusted simultaneously by setting the vertical limiting member. When there is no external force acting on the sliding member, the vertical limiting member locks the vertical rotation mechanism under the action of the reset member, thus locking the robotic arm for convenient rope-pulling training. When the user needs to adjust the vertical position of the robotic arm, the user controls the drive device via a switch. The drive device generates an external force that moves the sliding member, causing the horizontal limiting member to disengage from the horizontal rotation mechanism, and the vertical limiting member to disengage from the vertical rotation mechanism. This allows the user to control the switch with one hand and pull the robotic arm with the other to adjust its position, making it very convenient to adjust the robotic arm to the appropriate position. If the switch is released, the slider returns to a state without external force. Under the action of the reset member, the horizontal limit member locks the horizontal rotation mechanism, and the vertical limit member locks the vertical rotation mechanism. In this way, the reset member relocks the horizontal and vertical rotation mechanisms of the robotic arm, making it convenient for users to perform rope-pulling training.
[0022] When the drive unit malfunctions or the robotic arm loses power, the user can disengage the drive unit from the sliding component by controlling the clutch. The user can then manually pull the pull cord, creating an external force that moves the sliding component, disengaging the horizontal limiter from the horizontal rotation mechanism, and simultaneously disengaging the vertical limiter from the vertical rotation mechanism. This allows the user to control the pull cord with one hand and pull the robotic arm with the other to adjust its position conveniently. This clutch mechanism also allows for easy switching between manual and automatic modes for the robotic arm's adjustment mechanism. When the adjustment mechanism is in automatic mode and there is no power or the drive unit malfunctions, it can be switched back to manual mode with a single button press, without affecting normal user operation.
[0023] The fitness robotic arm of this invention features a simple structure, low cost, long lifespan, and ease of installation and maintenance. Furthermore, in the event of power failure or a malfunction in the drive mechanism, the adjustment mechanism can be easily switched between manual and automatic modes via a clutch device, without affecting normal user operation. This provides users with a fitness robotic arm that is compatible with both automatic and manual modes. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention. Example 1
[0055] like Figures 1 to 23 As shown, a fitness robotic arm with a horizontal rotation mechanism includes a body 1 and a horizontal rotation mechanism 2. The body 1 is provided with the horizontal rotation mechanism 2, which includes a stator 21 and a central spindle 22. The stator 21 and the central spindle 22 form a limiting groove 23.
[0056] As a further explanation of this embodiment, the horizontal rotation mechanism 2 also includes a first bearing seat 24 and a second bearing seat 25. The first bearing seat 24 is installed on the inner end of the central spindle 22, and the second bearing seat 25 is installed on the outer end of the central spindle 22.
[0057] As a further explanation of this embodiment, the main body 1 is also provided with an adjustment mechanism 4, which includes a sliding member 41, a reset member 42 and a horizontal limiting member 43.
[0058] As a further explanation of this embodiment, the sliding member 41 is provided with a reset member 42, and the sliding member 41 is connected to a horizontal limiting member 43, which is connected to the horizontal rotation mechanism 2. The horizontal limiting member 43 is a limiting steel ball 431 disposed on the inner side of the sliding member 41, and the limiting steel ball 431 matches the limiting groove 23. The limiting groove 23 is used to restrict the movement of the limiting steel ball 431, and the outer side of the stator 21 is connected to the body 1. The number of limiting steel balls 431 can be set to more than two as needed, preferably four to six.
[0059] Specifically, when there is no external force acting on the sliding member 41, under the action of the reset member 42, the sliding member 41 presses the limiting steel ball 431 into the limiting groove 23, thereby locking the horizontal limiting member 43 into the horizontal rotation mechanism 2. When an external force drives the sliding member 41 to move, the sliding member 41 moves to the right, creating a larger space between the limiting steel ball 431 and the limiting groove 23, thereby causing the limiting steel ball 431 to disengage from the limiting groove 23, that is, the horizontal limiting member 43 disengages from the horizontal rotation mechanism 2, and the horizontal rotation mechanism rotates freely.
[0060] In this embodiment, the reset member 42 is selected as a spring with elastic reset function. One end of the spring abuts against the sliding member 41, and the other end of the spring can be set on the body 1 or on a part that does not slide with the sliding member 41, such as the bearing seat of the horizontal rotation mechanism 2, to achieve its elastic reset function.
[0061] As a further explanation of this embodiment, the sliding member 41 is provided with a support surface 411 for mounting the reset member, and one end of the reset member 42 abuts against the support surface. In this embodiment, the reset member 42 is selected as a spring with elastic reset function. The other end of the spring can be provided on the body 1 or on a part that does not slide with the sliding member 41, such as the bearing seat of the horizontal rotation mechanism 2, to achieve its elastic reset function.
[0062] As a further explanation of this embodiment, the slider 41 is provided with a first sliding surface 412, a second sliding surface 414 and a guide surface 413 disposed between the first sliding surface 412 and the second sliding surface 414.
[0063] As a further explanation of this embodiment, the slider 41 can be a component capable of linear motion, such as a sliding block or a circular slider. In this embodiment, the slider 41 is a hollow circular slider. The circular slider is integrally hollow and cylindrical. The outer side of the circular slider is provided with a support surface 411 for mounting the reset component. The interior of the circular slider is provided with a first sliding surface 412, a second sliding surface 414, and a guide surface 413 disposed between the first sliding surface 412 and the second sliding surface 414. The support surface can be relatively matched according to the position of the reset component 42, which will not be elaborated here.
[0064] Specifically, when there is no external force acting on the slider 41, the first sliding surface 412 of the slider 41 is in contact with the limiting steel ball 431.
[0065] Specifically, when an external force drives the slider 41 to move, the guide surface 413 of the slider 41 contacts the limiting steel ball 431, causing the limiting steel ball 431 to disengage from the limiting groove 23; after the limiting steel ball 431 completely disengages from the limiting groove 23, the second sliding surface 414 of the slider 41 contacts the limiting steel ball 431.
[0066] As a further explanation of this embodiment, the adjustment mechanism 4 further includes a vertical limiting member 44, which is disposed on the side of the sliding member 41 and is connected to the vertical rotation mechanism 3.
[0067] Specifically, when there is no external force acting on the sliding member 41, under the action of the reset member 42, the horizontal limiting member 43 locks the horizontal rotation mechanism 2, and the vertical limiting member 44 locks the vertical rotation mechanism 3.
[0068] Specifically, when an external force drives the sliding member 41 to move, the horizontal limiting member 43 disengages from the horizontal rotating mechanism 2, and the vertical limiting member 44 disengages from the vertical rotating mechanism 3, allowing the horizontal rotating mechanism and the vertical rotating mechanism 3 to move freely simultaneously.
[0069] As a further explanation of this embodiment, the vertical rotation mechanism 3 includes a rotating link assembly 31 and a robotic arm seat assembly 32. One end of the rotating link assembly 31 is connected to the robotic arm seat assembly 32, and the other end of the rotating link assembly 31 is provided with a transmission tooth groove 33. The limiting post 441 is provided in the transmission tooth groove 33.
[0070] As a further explanation of this embodiment, the vertical limiting member 44 comprises a limiting post 441 and a limiting elastic member 442 disposed on the outer side of the sliding member 41. One end of the limiting elastic member 442 abuts against the inner wall of the main body, and the other end of the limiting elastic member 442 abuts against the limiting post 441. The limiting post 441 is connected to the sliding member 41. The limiting elastic member 442 is a spring, rubber, silicone, or other component with elastic return properties.
[0071] In this embodiment, the outer surface of the sliding member 41 is provided with a sliding member inclined surface 415, and the limiting post 441 is provided with a limiting post inclined surface 4411. The sliding member inclined surface 415 and the limiting post inclined surface 4411 are matched. Specifically, the sliding member 41 moves horizontally in a straight line. Under the action of the sliding member inclined surface 415 and the limiting post inclined surface 4411, the sliding member 41 drives the limiting post 441 to move upward, thereby driving the limiting elastic member 442 to move upward, pushing the transmission steel ball into the transmission tooth groove, so that the vertical limiting member 44 locks the vertical rotation mechanism 3.
[0072] As a further explanation of this embodiment, the sliding member 41 is connected to a pull rope connector 5, the pull rope connector 5 is connected to a pull rope 6, the pull rope 6 is connected to a pull rope switch 7, and the pull rope switch 7 is disposed on the outer wall of the body 1.
[0073] The working principle of this embodiment is as follows: The robotic arm is equipped with an adjustment mechanism 4 and a horizontal rotation mechanism 2. The adjustment mechanism 4 can limit the horizontal rotation mechanism 2. By setting a sliding member 41, a reset member 42, and a horizontal limit member 43, when there is no external force acting on the sliding member 41, the horizontal limit member 43 locks the horizontal rotation mechanism 2 under the action of the reset member 42, thus locking the robotic arm for the user to perform rope-pulling training. When the user needs to adjust the position of the robotic arm, the user controls the drive device through a switch, and the drive device generates an external force that moves the sliding member 41, causing the horizontal limit member 43 to disengage from the horizontal rotation mechanism 2. In this way, the user controls the switch with one hand and pulls the robotic arm with the other hand to adjust the position of the robotic arm, which is very convenient to adjust the robotic arm to a suitable position. If the switch is released, the sliding member 41 returns to a state without external force, and the horizontal limit member 43 locks the horizontal rotation mechanism 2 under the action of the reset member 42, thus re-locking the horizontal rotation mechanism 2 of the robotic arm for the user to perform rope-pulling training.
[0074] Based on the above structure, the adjustment mechanism 4 can also be equipped with a vertical limiting member 44. The vertical limiting member 44 is located on the side of the sliding member 41 and is connected to the vertical rotation mechanism 3. When the adjustment mechanism 4 adjusts the horizontal rotation mechanism 2, the vertical rotation mechanism 3 can be adjusted simultaneously by setting the vertical limiting member 44. When there is no external force acting on the sliding member 41, the vertical limiting member 44 locks the vertical rotation mechanism 3 under the action of the reset member 42. This locks the robotic arm, making it convenient for the user to perform rope 6 training. When the user needs to adjust the vertical position of the robotic arm, the user controls the drive device through a switch. The drive device generates an external force that moves the sliding member 41, causing the horizontal limiting member 43 to disengage from the horizontal rotation mechanism 2 and the vertical limiting member 44 to disengage from the vertical rotation mechanism 3. In this way, the user can control the switch with one hand and pull the robotic arm with the other hand to adjust the position of the robotic arm, making it very convenient to adjust the robotic arm to a suitable position. If the switch is released, the slider 41 returns to a state without external force. Under the action of the reset member 42, the horizontal limit member 43 locks the horizontal rotation mechanism 2, and the vertical limit member 44 locks the vertical rotation mechanism 3. In this way, the reset member 42 relocks the horizontal rotation mechanism 2 and the vertical rotation mechanism 3 of the robotic arm, making it convenient for users to perform rope pulling training.
[0075] In this embodiment, the user manually pulls the pull rope 6 via the pull rope switch 7. Pulling the pull rope 6 generates an external force that drives the sliding member 41 to move, causing the horizontal limiting member 43 to disengage from the horizontal rotation mechanism 2, and simultaneously the vertical limiting member 44 to disengage from the vertical rotation mechanism 3. This allows the user to control the pull rope 6 with one hand and pull the robotic arm with the other to adjust its position, making it very convenient to adjust the robotic arm to a suitable position. Example 2
[0076] The difference from Embodiment 1 is that the reset component 42 is an electromagnetic clutch device, a magnetic attraction device, a rubber component, or a silicone component.
[0077] Based on the above-described modification of the reset member 42 or the use of the reset member 42 in Embodiment 1, as a further explanation of this embodiment, the sliding member 41 is connected to a driving device (not shown in the figure). The external force generated by the driving device is used to drive the sliding member 41 to move, causing the horizontal limiting member 43 to disengage from the horizontal rotation mechanism 2, and the vertical limiting member 44 to disengage from the vertical rotation mechanism 3. The driving device can be an existing linear motor driving device, a lead screw and nut driving device, an electromagnetic clutch driving device, or a magnetic attraction driving device.
[0078] As a further explanation of this embodiment, the driving device is connected to a clutch device (not shown in the figure), which is used to keep the driving device and the sliding member 41 in two states: connected and disconnected.
[0079] The working principle of this embodiment is as follows: The robotic arm is driven by an existing linear motor drive, lead screw and nut drive, electromagnetic clutch drive, or magnetic attraction drive to move the adjustment mechanism 4. Additionally, by setting up an adjustment mechanism 4, the limit adjustment of both the horizontal rotation mechanism 2 and the vertical rotation mechanism 3 can be achieved simultaneously. By setting up a sliding member 41, a reset member 42, a horizontal limit member 43, and a vertical limit member 44, when there is no external force acting on the sliding member 41, under the action of the reset member 42, the horizontal limit member 43 locks the horizontal rotation mechanism 2, and the vertical limit member 44 locks the vertical rotation mechanism 3. This locking of the robotic arm facilitates user training with the rope 5. When the user needs to adjust the position of the robotic arm, the user controls the drive device through a switch, which generates an external force that moves the sliding member 41, causing the horizontal limit member 43 to disengage from the horizontal rotation mechanism 2, and simultaneously the vertical limit member 44 to disengage from the vertical rotation mechanism 3. This allows the user to control the switch with one hand and pull the robotic arm with the other to adjust its position, making it very convenient to position the robotic arm appropriately. If the switch is released, the slider 41 returns to a state without external force. Under the action of the reset member 42, the horizontal limit member 43 locks the horizontal rotation mechanism 2, and the vertical limit member 44 locks the vertical rotation mechanism 3. Thus, the reset member 42 re-locks the horizontal and vertical rotation mechanisms of the robotic arm, facilitating rope-pulling training for the user.
[0080] In this embodiment, the user controls a switch (not shown in the figure) to drive the slider 41 to move, causing the horizontal limiting member 43 to disengage from the horizontal rotation mechanism 2, and simultaneously the vertical limiting member 44 to disengage from the vertical rotation mechanism 3. This allows the user to operate the control switch with one hand and pull the robotic arm with the other to adjust its position, making it very convenient to adjust the robotic arm to a suitable position.
[0081] When the drive unit malfunctions or the robotic arm loses power, the user can control the clutch device to disengage the drive unit from the sliding member 41, switching to the manual mode of Embodiment 1. The user can then manually pull the pull rope 5 via the pull rope switch 6. Pulling the rope 5 generates an external force that moves the sliding member 41, causing the horizontal limiting member 43 to disengage from the horizontal rotation mechanism 2, and simultaneously the vertical limiting member 44 to disengage from the vertical rotation mechanism 3. This allows the user to control the pull rope 5 with one hand and pull the robotic arm with the other to adjust its position, making it very convenient to adjust the robotic arm to the appropriate position. By incorporating the clutch device, the robotic arm's adjustment mechanism 4 can be easily switched between manual and automatic modes. When the robotic arm's adjustment mechanism 4 is in automatic mode and there is no power, or when the drive unit malfunctions, it can be switched to manual mode with a single button press, without affecting normal user operation.
[0082] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
