Description

Technical Field

[0001] This invention relates to fitness equipment, specifically to an intelligent upper and lower limb coordinated training system. Background Technology

[0002] Chinese patent discloses an adjustable pedal stepper with application number CN201721011371.5. The stepper includes: a stepper base, a stepper frame, a left cylinder, a right cylinder, a left full-foot pedal, and a right full-foot pedal. The stepper frame is mounted on the stepper base. The left full-foot pedal and the right full-foot pedal are respectively connected to the stepper frame. The left cylinder is connected to the left full-foot pedal and the stepper base, and the right cylinder is connected to the right full-foot pedal and the stepper base. It also includes a left half-foot pedal and a right half-foot pedal. The left full-foot pedal and the right full-foot pedal are respectively provided with a plurality of T-shaped grooves, and the left half-foot pedal and the right half-foot pedal are respectively provided with a plurality of T-shaped protrusions, which cooperate with the T-shaped grooves.

[0003] This stepper utilizes a transmission mechanism with left and right cylinders to provide stable resistance. This results in significant resistance when the user steps on the left and right full-foot pedals, effectively targeting the legs and hips. However, the stepper does not make contact with the user's upper limbs and therefore does not provide the balance training benefits for older adults. Summary of the Invention

[0004] The present invention provides an intelligent upper and lower limb coordinated training system to solve the problem that the existing technology cannot train the upper and lower limbs at the same time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention discloses an intelligent upper and lower limb linkage training system, comprising: two upper and lower limb linkages, each of which includes: a mounting frame, a rotating base, a foot pedal, a rotating arm, a pulling arm, and a swing arm. The mounting frame is hinged to the middle of the rotating base, and the axis of rotation of the rotating base relative to the mounting frame is horizontal. Each end of the rotating base is hinged to one end of a rotating arm, the rotating arm is hinged to the bottom end of the pulling arm, and the top end of the pulling arm is hinged to one end of the swing arm. There are two sets of rotating arms and pulling arms between the rotating base and the swing arm. The middle of the swing arm is hinged to the top of the mounting frame, and both ends of the swing arm are for the trainee to grip. A foot pedal is installed above each end of the rotating base. A display frame is placed between the two upper and lower limb linkages and is connected to the mounting frames of both linkages. A sensor is installed at the hinge of the rotating base and is used to detect the number of swings of the rotating base. A controller is installed inside the display frame and is connected to the sensor. A display screen is installed on the display frame and is connected to the controller. The display screen is used to display the number of swings of the rotating base.

[0007] Preferably, the rotating base includes: a first support rod and a second support rod, both of which are hinged to the mounting frame at their middle parts. There is a distance between the hinge point at the middle of the first support rod and the hinge point at the middle of the second support rod. One end of the first support rod and one end of the second support rod are both hinged to a rotating arm, and the other ends of the first support rod and the other ends of the second support rod are both hinged to another rotating arm.

[0008] Preferably, each rotating arm includes: two rotating plates, with one end of the first support rod and one end of the second support rod extending into the space between the two rotating plates, the middle of the rotating plate being hinged to the pulling arm, and the first support rod and the second support rod being installed on both sides of the hinge between the pulling arm and the rotating plate.

[0009] Preferably, a resistance component is installed between the rotating base and the mounting bracket, the resistance component being used to increase the resistance to rotating the rotating base.

[0010] Preferably, a spring is installed between the first support rod and the second support rod.

[0011] Preferably, the resistance assembly includes: a first strong magnet and a second strong magnet, the first strong magnet being aligned with the second strong magnet, the first strong magnet being mounted on a rotating base, and the second strong magnet being mounted on a mounting bracket.

[0012] Preferably, the mounting frame includes: a ground-mounting frame, a mounting plate, and a mounting column. The ground-mounting frame is installed on the ground, the mounting plate is installed on the ground-mounting frame, a second strong magnet is installed on the mounting plate, the mounting column is erected on the ground-mounting frame, and a rotating base and the middle part of the swing arm are installed on the mounting column.

[0013] Preferably, the mounting bracket further includes a support portion mounted on the top of the mounting column, with a swing arm hinged to the middle of the support portion.

[0014] Preferably, the support includes a welding cylinder, a welding block, and a support shaft. The mounting column has an insertion hole for the welding cylinder and the welding block to extend into. The support shaft has a T-shaped structure, passes through the welding cylinder, has its large end inside the welding cylinder, and has a swing arm hinged to its small end. The welding block is inserted into the end of the welding cylinder located in the insertion hole. Both the welding block and the welding cylinder are welded to the mounting column.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) By setting up two upper and lower limb linkage devices, two people can train at the same time.

[0017] 2) By setting up a display rack, sensors, controllers and displays, there are two displays, one display corresponding to one upper and lower limb linkage, so that trainees can see their training status. The two displays share one display rack and controller, reducing the use of parts and reducing the cost of use. At the same time, the two upper and lower limb linkages are set up close to each other, reducing the space occupied.

[0018] 3) By setting up an upper and lower limb linkage mechanism including: a mounting frame, a rotating base, a foot pedal, a rotating arm, a pulling arm, and a swing arm, it achieves the goal of rotating the base when the foot pedal swings, and rotating the base, through the rotating arm and pulling arm, driving the swing arm to rotate. Handles are provided at both ends of the swing arm for the trainee to grip, thus enabling simultaneous hand and foot movement and training of both upper and lower limbs. This avoids the limitation of existing steppers that only train the legs and buttocks, which only provide foot movement. This application is a sports device developed by imitating the principle of a swing dance, enabling simultaneous deflection and swinging of the upper and lower limbs when the body steps, aiming to train the body's balance and coordination, making the body posture and physique more graceful. It can simultaneously train the shoulder joints and arm strength, as well as the buttocks, knee joints, and ankle muscles. It is suitable for young and elderly people, children, etc. The following functions are achieved: Function 1: Balance and Coordination: The body stands on the foot pedal with both hands gripping the ends of the swing arm, swinging left and right in a coordinated manner. Function 2: Trains the glutes, hips, and ankle muscles. Holding the bar in the middle with both hands primarily trains the lower limb muscles.

[0019] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0026] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0027] Example 1:

[0028] like Figures 1 to 4 As shown, this invention discloses an upper and lower limb linkage training device, comprising: two upper and lower limb linkage devices 1, each upper and lower limb linkage device 1 including: a mounting frame 11, a rotating base frame 12, a foot pedal 13, a rotating arm 14, a pulling arm 15, and a swing arm 16. The mounting frame 11 is hinged to the middle of the rotating base frame 12, and the axis of rotation of the rotating base frame 12 relative to the mounting frame 11 is located in the horizontal direction. Each end of the rotating base frame 12 is hinged to one end of a rotating arm 14, the rotating arm 14 is hinged to the bottom end of the pulling arm 15, and the top end of the pulling arm 15 is hinged to one end of the swing arm 16. There are two sets of rotating arms 14 and pulling arms 15 between the rotating base frame 12 and the swing arm 16. The boom 16 is hinged to the top of the mounting frame 11 in the middle. The two ends of the boom 16 are for the trainee to hold. A foot pedal 13 is installed above each end of the rotating base 12. The display frame 2 is placed between the two upper and lower limb linkages 1 and is connected to the mounting frame 11 of the two upper and lower limb linkages 1. The sensor (not shown) is installed at the hinge of the rotating base 12 and is used to detect the number of swings of the rotating base 12. The controller (not shown) is installed inside the display frame 2 and is connected to the sensor. The display screen 3 is installed on the display frame 2 and is connected to the controller. The display screen 3 is used to display the number of swings of the rotating base 12.

[0029] The rotating base 12 includes a first support rod 121 and a second support rod 122. Both the first support rod 121 and the second support rod 122 are hinged to the mounting frame 11 at their midpoints. There is a distance between the hinge point of the first support rod 121 and the hinge point of the second support rod 122. One end of the first support rod 121 and one end of the second support rod 122 are hinged to a rotating arm 14, and the other end of the first support rod 121 and the other end of the second support rod 122 are hinged to another rotating arm 14. The double support of the first support rod 121 and the second support rod 122 ensures the strength of the entire rotating base 12. Since the rotating base 12 bears a large load, this design extends its service life.

[0030] Each rotating arm 14 includes two rotating plates, with one end of the first support rod 121 and one end of the second support rod 122 extending into the space between them. The middle of each rotating plate is hinged to a pulling arm 15, and the first and second support rods 121 and 122 are mounted on either side of the hinge point between the pulling arm 15 and the rotating plate. The two rotating plates are fitted together on both sides of the ends of the first and second support rods 121 and 122, achieving symmetrical mounting at the ends. Finally, the pedal 13 is stably connected to the two rotating plates, aligning the center of the pedal 13 with the first and second support rods 121 and 122. This ensures that the force center of the pedal 13 is on the first and second support rods 121 and 122, allowing the force on the pedal 13 to be fully applied to them. This guarantees sufficient support for the bottom of the pedal 13, ensuring support strength and preventing instability caused by a weak connection between the bottom of the pedal 13 and the rotating plate.

[0031] A resistance assembly 17 is installed between the rotating base 12 and the mounting frame 11. The resistance assembly 17 is used to increase the resistance to rotating the rotating base 12. The resistance assembly 17 increases the resistance to rotating the rotating base 12, thereby increasing the training intensity and achieving the training objective.

[0032] A spring 18 is installed between the first support rod 121 and the second support rod 122. Since the first support rod 121 and the second support rod 122 are both hinged to the rotating plate, and the first support rod 121 and the second support rod 122 play the same supporting role, the spring 18 ensures good connection stability between the first support rod 121 and the second support rod 122. This avoids excessive vibration of the pedal 13 due to the slightly different rotation pace of the first support rod 121 and the second support rod 122, reduces oscillation, and improves the stability after installation.

[0033] The resistance assembly 17 includes a first strong magnet 171 and a second strong magnet 172. The first strong magnet 171 and the second strong magnet 172 are aligned. The first strong magnet 171 is mounted on the rotating base 12, and the second strong magnet 172 is mounted on the mounting bracket 11. Since the first strong magnet 171 is mounted on the rotating base 12, a hole needs to be drilled in the rotating base 12 to facilitate its installation. The rotating base 12 is configured as a first support rod 121 and a second support rod 122. This strengthens the support while preventing insufficient strength of the rotating base 12 due to the need to create a mounting position for the first strong magnet 171. The first strong magnet 171 and the second strong magnet 172 are positioned opposite each other, repelling each other. This maintains the initial horizontal state of the rotating base 12, meaning both pedals 13 are horizontal, thus increasing the strength of rotating the rotating base 12 and further improving the rotational strength.

[0034] Mounting frame 11 includes: a ground-mounting frame 111, a mounting plate 112, and a mounting column 113. The ground-mounting frame 111 is installed on the ground, and the mounting plate 112 is mounted on the ground-mounting frame 111. A second strong magnet 172 is mounted on the mounting plate 112. The mounting column 113 stands on the ground-mounting frame 111, and a rotating base frame 12 and the middle part of a swing arm 16 are mounted on the mounting column 113. The ground-mounting frame 111 is stably installed on the ground, providing a supporting foundation for the mounting plate 112 and the mounting column 113, enabling the mounting plate 112 and the mounting column 113 to grip the ground stably.

[0035] The mounting bracket 11 also includes a support portion, which is mounted on the top of the mounting column 113, and the middle part of the swing arm 16 is hinged to the support portion. The support portion provides a hinged basis for the rotation of the swing arm 16, so that the swing arm 16 can be stably supported and can maintain rotation.

[0036] The support includes a welding cylinder 114, a welding block 115, and a support shaft 116. The mounting post 113 has an insertion hole for the welding cylinder 114 and the welding block 115 to extend into. The support shaft 116 has a T-shaped structure and passes through the welding cylinder 114. The large end of the support shaft 116 is located inside the welding cylinder 114, and the small end of the support shaft 116 is hinged to a swing arm 16. The welding block 115 is inserted into the end of the welding cylinder 114 located in the insertion hole. Both the welding block 115 and the welding cylinder 114 are welded to the mounting post 113. The installation of the swing arm 16 means that the welding cylinder 114 is under stress. By setting the welding cylinder 114 to be inserted into the mounting column 113, when under stress, the welding cylinder 114 tilts upwards. When tilted upwards, the welding cylinder 114 can be blocked by the inner wall of the mounting column 113, making it less likely for the welding cylinder 114 to detach from the mounting column 113. The setting of the welding block 115 makes the welding joint of the welding cylinder 114 non-circular, which can ensure the welding strength between the welding cylinder 114 and the mounting column 113 and make the welding joint adhere better. The support shaft 116 passes through the welding cylinder 114, and the shape of the support shaft 116 is set so that the support shaft 116 can hook the welding cylinder 114. When the support shaft 116 is pressed down, the welding cylinder 114 also tends to be pressed down. The welding cylinder 114 can be blocked by the insertion hole when under stress, avoiding surface-to-surface contact, which would easily cause the connection between the support shaft 116 and the mounting column 113 to detach, thus ensuring the stability of the installation.

[0037] In this application, firstly, to achieve foot pedal rotation, a foot pedal 13 and a rotating base are designed. This allows the trainee to rotate the rotating base 12 after stepping on the foot pedal 13, thereby training the legs and buttocks. Secondly, to drive the swing arm 16 to rotate, a rotating arm 14 and a pulling arm 15 are provided. The foot pedal 13 is hinged to the rotating base 12 via the rotating arm 14, and the rotating arm 14 provides the hinge base for the pulling arm 15. This achieves the goal of rotating the swing arm 16 through the rotating arm 14, pulling arm 15, and rotating base 12 after the foot pedal 13 is stepped on, thus rotating the arm together and training the arm joints. Furthermore, since a very smooth swing of the rotating base 12 would not meet training requirements, and excessive fluctuation would make it difficult for trainees to maintain balance, a resistance component 17 was incorporated. This component ensures stability under its force, increasing the resistance to the rotation of the base 12 and thus enhancing training intensity. The resistance component 17 also improves stability, preventing the base 12 from easily rotating to large angles and thus improving stability when stepped on. The resistance component 17 includes a first strong magnet 171 and a second strong magnet 172, providing sufficient resistance to ensure its functionality. Finally, to ensure the strength of the rotating base 12 and provide a mounting base for the second strong magnet 172 (i.e., an mounting hole for the second strong magnet 172), a first support rod 121 and a second support rod 122 were incorporated to form the rotating base 12, ensuring its strength. Finally, since the first support rod 121 and the second support rod 122 serve the same purpose and are simultaneously hinged to the rotating arm 14, a spring 18 is provided to prevent excessive oscillation caused by the inconsistent rotation pace of the first support rod 121 and the second support rod 122 relative to the rotating arm 14. This provides a buffer connection between the first support rod 121 and the second support rod 122, ensuring smooth rotation of both the first support rod 121 and the second support rod 122 while avoiding excessive oscillation caused by inconsistent rotation pace, thus improving the stability of stepping on the pedal 13.

[0038] Example 2:

[0039] The difference between this embodiment and embodiment 1 is that, in order to facilitate the adjustment of the position of the second strong magnet 172 relative to the first strong magnet 171, this embodiment makes specific limitations on the installation method of the mounting plate 112 and the first strong magnet 172 based on embodiment 1, while other structures remain unchanged.

[0040] like Figure 5As shown, the second strong magnet 172 is installed in the magnet base 173. A slide rod 174 extends from the magnet base 173. The slide rod 174 can slide in the sliding hole 110 of the mounting plate 112. A positioning mechanism 19 is installed on the mounting plate 112. The positioning mechanism 19 is used to position the magnet base 173 on the mounting plate 112.

[0041] A strip-shaped anti-detachment block 175 is installed on the end of the slide rod 174 away from the magnet base 173. The second strong magnet 172, the slide rod 174 and the magnet base 173 are cylindrical structures. The anti-detachment block 175 can pass through the sliding hole 110. The side of the mounting plate 112 away from the magnet base 173 is recessed to form a strip-shaped groove. The strip-shaped groove is parallel to the sliding hole 110. One end of the anti-detachment block 175 is threadedly connected to a screw (not shown in the figure) that extends into the strip-shaped groove. The system employs an anti-detachment block 175 and a screw structure. When the magnet base 173 is installed onto the mounting plate 112, there is no screw on the anti-detachment block 175. The anti-detachment block 175 and the sliding rod 174 are passed through the mounting plate 112. Then, the magnet base 173 is rotated so that the long side of the anti-detachment block 175 is perpendicular to the sliding hole 110. Finally, the screw is threaded onto the anti-detachment block 175, extending into the slot. The screw engages with the slot, and the anti-detachment block 175 hooks onto the mounting plate 112. At this point, the anti-detachment block 175 cannot pass through the sliding hole 110, thus restricting the anti-detachment block 175, sliding rod 174, and magnet base 173 from rotating relative to the mounting plate 112. They can only move relative to the mounting plate 112 in a direction parallel to the sliding hole 110. This prevents the magnet base 173 from detaching from the mounting plate 112 and provides conditions for subsequent adjustment of the alignment between the second strong magnet 172 and the first strong magnet 171.

[0042] The positioning mechanism 19 includes a positioning plate 191, a positioning rack 192, an annular cylinder 193, and a lifting spring 194. A protruding section in the middle of the mounting plate 112 forms an insert 119 that is inserted into the grounding frame 111. The positioning plate 191 is installed below the mounting plate 112. An annular cylinder 193 is fixed in the middle of the positioning plate 191. A lifting spring 194 is installed between the annular cylinder 193 and the mounting plate. The positioning plate 191 is recessed to form a positioning groove into which the anti-detachment block 175 is placed. The positioning rack 192 is installed in the positioning groove and engages with the anti-detachment block 175. The mounting plate and the grounding frame 111 are positioned by positioning bolts 117. The lifting spring 194 ensures a larger gap between the mounting plate 112 and the positioning plate 191, i.e., a distance between the anti-detachment block 175 and the positioning groove. When adjusting the position of the second strong magnet 172, the positioning bolt 117 disengages from the ground mounting bracket 111, and the anti-detachment block 175 does not contact the positioning rack 192. Then, by moving the magnet base 173, the position of the second strong magnet 172 can be adjusted to be opposite to the first strong magnet 171. This avoids the difficulty of operation caused by the need to align the centers of the first strong magnet 171 and the second strong magnet 172, and simplifies the production process.

[0043] In this embodiment, firstly, a swinging rotating base frame 12 is provided; then, to increase the swing resistance of the rotating base frame 12, a first strong magnet 171 and a second strong magnet 172 are arranged relative to each other, achieving sufficient swing resistance when the rotating base frame 12 swings, thus improving the training effect; next, a mounting plate 112 is provided to install the second strong magnet 172; then, to facilitate the adjustment of the second strong magnet 172 to align with the first strong magnet 171, the second strong magnet 172 is designed to move on the mounting plate 112; finally, to facilitate the installation of the second strong magnet 172, a magnet base 173, a slide rod 174, an anti-detachment block 175, and a screw are provided, and the magnet base 173, slide rod 174, and anti-detachment block 175 can be manufactured together in a mold during production. This design avoids weak connections between the anti-detachment block 175 and the slide bar 174, preventing the anti-detachment block 175 from easily detaching. It ensures that the magnet seat 173 and the second strong magnet 172 can slide on the mounting plate 112 without detaching. Furthermore, a positioning plate 191, a positioning rack 192, and a lifting spring 194 are provided. After the positioning bolt on the mounting plate 112 is detached, the anti-detachment block 175 can be completely detached from the positioning rack 192 under the elastic force of the lifting spring 194. After the positioning bolt is connected to the grounding frame 111, the anti-detachment block 175 and the positioning rack 192 are engaged, thereby positioning the magnet seat 173 and the second strong magnet 172. Thus, the positioning bolt 117 not only connects to the grounding frame 111 but also positions the positioning mechanism 19 and the anti-detachment block 175, ensuring that the position does not change after adjustment.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
