Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically, it relates to a rotation drive device and fitness equipment. Background Technology

[0002] Currently, most fitness equipment for exercising the inner and outer thigh muscles uses steel cables for resistance transmission, stimulating the muscles with weights to achieve the desired workout. However, steel cable connections are not smooth, affecting the user experience. Furthermore, assembling and maintaining the machines is time-consuming and labor-intensive. Additionally, different user groups have significantly different load requirements for fitness equipment, meaning that existing equipment is suitable for a relatively small user base.

[0003] Therefore, developing a fitness device that allows for smooth movement, provides a good user experience, is easy to maintain, reduces after-sales costs, and is suitable for a wider range of users is an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a fitness equipment that allows for smooth movement during use, provides a good user experience, is easy to maintain, reduces after-sales costs, and is suitable for a wider range of users.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] This utility model proposes a fitness equipment, including:

[0007] The fixing part includes a rotating support part and a fitness equipment support part, wherein the rotating support part is disposed on the fitness equipment support part;

[0008] A force-applying rotating part has a pedal end and an output end formed thereon. The pedal end is configured to be driven to rotate around the rotating support part by the force applied to it by the exerciser, so as to drive the output end to rotate around the rotating support part.

[0009] The rotatable follower includes a linkage component, one end of which is configured to be rotatably connected to the output end, and the other end of which is used to output force externally;

[0010] The barbell moving part includes an adjustable counterweight part, a rotating part, and a moving part. The rotating end of the rotating part is rotatably connected to the support part of the fitness equipment. The adjustable counterweight part is disposed on the extension end of the rotating part. One end of the moving part is rotatably connected to the output end, and the other end of the moving part is connected to the middle part of the rotating part.

[0011] In some embodiments of this application, the adjustable weight section includes an extension section and a mounting section. The mounting section is disposed on the support section of the fitness equipment, and the middle part of the extension section is connected to the extension end of the rotating section. An elastic band is fitted onto the mounting section and the extension section. Since the counterweight force generated by hanging barbell plates is relatively large, the load is too heavy for lighter individuals, especially beginners in thigh abduction exercises. Therefore, the addition of an elastic band broadens the applicability of the fitness equipment, thereby improving the user experience for a wider range of users.

[0012] In some embodiments of this application, the hanging part includes a support column and a first stop, one end of the support column is connected to the fitness equipment support, and the first stop is connected to the other end of the support column;

[0013] With the elastic band fitted over the support column, the first stop is used to stop the support column.

[0014] In some embodiments of this application, the height increases from the middle of the extension to the end of the extension.

[0015] In some embodiments of this application, the adjustable counterweight further includes an original position support, which is connected to the fitness equipment support.

[0016] When the moving part does not exert force on the rotating part, the middle part of the extension abuts against the original position support part.

[0017] In some embodiments of this application, in the original position state, the pedal end, the rotating support part and the output end extend sequentially along a first direction, and the connecting rod part and the barbell moving part extend sequentially along a second direction, wherein the first direction and the second direction are opposite to each other;

[0018] When the exerciser drives the pedaling part to rotate to its limit position, the linkage component pushes the moving part to move to its limit position along the second direction;

[0019] When the exerciser drives the pedaling part to rotate to its original position, the connecting rod pulls the moving part to move to its original position along the first direction.

[0020] In some embodiments of this application, the force-applying rotating part further includes a rotating shaft, which is disposed at the connection between the pedal end and the output end;

[0021] The rotating support includes a vertical bearing housing;

[0022] The rotating shaft is rotatably connected to the vertical bearing seat, and the force-applying rotating part rotates around the rotating support part.

[0023] In some embodiments of this application, the foot pedal includes a foot pedal, a rotating frame, and a leg pad. The leg pad is connected to the foot pedal, the foot pedal is connected to one end of the rotating frame, and the output end is connected to the other end of the rotating frame. When the exerciser's foot is on the foot pedal, the exerciser's leg is against the leg pad.

[0024] The rotating shaft is connected to the connection between the rotating frame and the output end.

[0025] In some embodiments of this application, the rotation follower further includes a first joint bearing, one end of which is connected to the end of the connecting rod component, and the other end of which is rotatably connected to the output end; the connecting rod component and the output end are rotatably connected via the first joint bearing.

[0026] In some embodiments of this application, the moving part is connected to the connecting rod component via a second joint bearing.

[0027] Compared with the prior art, the advantages and positive effects of this utility model are:

[0028] The counterweight of the adjustable counterweight section can be adjusted to suit different user groups;

[0029] By stepping on the pedal end, the exerciser applies force, driving the pedal end to rotate around the rotating support, which in turn drives the output end to rotate around the rotating support. The output end then drives the connecting rod assembly to reciprocate, outputting a reciprocating force to the barbell's moving part, thus achieving power transmission. The exerciser applies force to the pedal end, which transmits power through the connecting rod assembly, driving the barbell's moving part to move. This replaces the existing technology that uses steel cables to transmit force, making the force transmission smoother, reducing jamming, and also avoiding the labor time required for maintenance due to steel cable wear.

[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0070] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention.

Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0071] In some embodiments of this application, a linkage drive device is disclosed to replace the steel cable structure in the prior art. This device transmits the power of the exerciser's thigh abduction to the counterweight, thereby stimulating the muscles through the counterweight to achieve the purpose of exercise. The steel cable structure in the prior art is not smooth to connect and use, affecting the user experience. Furthermore, due to wear and tear on the steel cable, it requires regular maintenance and replacement, which is time-consuming and labor-intensive.

[0072] A linkage drive device includes a fixed part, a force-applying rotating part, and a rotation follower part.

[0073] In other embodiments of this application, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8As shown, this relates to a fitness equipment comprising the aforementioned linkage drive device and a barbell moving part 400. The user steps on the force-applying rotating part and applies force to it, driving the rotating part to rotate around a fixed part. The force-applying rotating part then drives a rotating follower part to rotate, which in turn outputs a force. The rotating follower part drives the barbell moving part 400 to reciprocate.

[0074] In some embodiments of this application, since the exerciser needs to step on the force-applying rotating parts with both feet, there are two force-applying rotating parts and two rotating follower parts, each for stepping on the barbell. The two force-applying rotating parts and two rotating follower parts are arranged opposite each other. The exerciser's legs apply force to the two force-applying rotating parts, which in turn drive the two rotating follower parts to move. The two rotating follower parts together apply force to the barbell moving part 400, thereby achieving the effect of leg muscle training.

[0075] The barbell moving part 400 includes the moving part 430.

[0076] The moving part 430 is configured to reciprocate under the action of an external force output by the rotating follower. The rotating follower drives the moving part 430 to reciprocate.

[0077] The fixed part includes a rotating support part.

[0078] like Figure 2 , Figure 4 As shown, the force-applying rotating part has a pedal end 210 and an output end 220 formed thereon. The pedal end 210 is configured to be driven to rotate around the rotating support part by the force applied to it by the exerciser, thereby causing the output end 220 to rotate around the rotating support part.

[0079] The rotating follower includes a connecting rod component 310, which is configured such that its end is rotatably connected to the output end 220.

[0080] The other end of the connecting rod assembly 310 is used to output force. The force output by the other end of the connecting rod assembly 310 can be a reciprocating force.

[0081] When the person using the fitness equipment is not operating it, the force-applying rotating part, the rotating follower part, and the barbell moving part 400 are in their original positions. This state is called the original position state.

[0082] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, in the original position, the direction in which the pedal end 210, the rotating support part and the output end 220 extend sequentially is the first direction, and the connecting rod part 310 and the barbell moving part 400 extend sequentially along the second direction.

[0083] The first direction and the second direction are set in opposite directions.

[0084] Since the extension directions of the pedal end 210, the rotating support part, and the output end 220 are opposite to the extension directions of the connecting rod part 310 and the barbell moving part 400, the various functional components of the fitness equipment can be more concentrated and compactly arranged, saving the floor space of the fitness equipment.

[0085] like Figure 1 , Figure 2 , Figure 8 As shown, the position of the force-applying rotating part, the rotating follower part, and the barbell moving part 400 when the fitness operator operates the fitness equipment and rotates the force-applying rotating part to the limit position is defined as the limit position. This state is the limit position state.

[0086] like Figure 1 , Figure 2 , Figure 8 As shown, when the exerciser drives the pedal end 210 to rotate to the limit position, the linkage component 310 pushes the moving part 430 to move to the limit position along the second direction.

[0087] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, when the exerciser drives the pedal end 210 to rotate to the original position, the connecting rod component 310 pulls the moving part 430 to move to the original position along the first direction.

[0088] In some embodiments of this application, the force-applying rotating part further includes a rotating shaft 230. The rotating shaft 230 is disposed at the connection between the pedal end 210 and the output end 220.

[0089] The rotating support includes a vertical bearing housing 111, and a rotating shaft 230 is rotatably connected to the vertical bearing housing 111. During the process of the pedal end 210 driving the output end 220 to rotate, the rotating shaft 230 is driven to rotate relative to the vertical bearing housing 111.

[0090] The fixed part also includes a fitness equipment support part 120. A rotating support part is provided on the fitness equipment support part 120.

[0091] Specifically, since the rotating shaft 230 is arranged vertically, the fixing part also includes a vertical support part 130 to match the orientation of the rotating shaft 230. The vertical support part 130 is arranged vertically on the fitness equipment support part 120. The base of the vertical bearing seat 111 is connected to the vertical support part 130. This ensures that the axial direction of the bearing hole of the vertical bearing seat 111 is vertical. The rotating shaft 230 can be inserted into the bearing hole of the vertical bearing seat 111.

[0092] Because the rotating shaft 230 experiences significant force during the rotation of the output end 220 driven by the pedal end 210, this force is directly transmitted to the vertical bearing housing 111. To prevent damage or loosening of the vertical bearing housing 111 due to excessive force, a limiting component is installed on one side of the vertical bearing housing 111. The limiting component abuts against the vertical bearing housing 111 to prevent displacement, loosening, or damage to the vertical bearing housing 111 under stress.

[0093] Specifically, the limiting assembly includes a fixing plate 1121 and a bolt 1122. The fixing plate 1121 has a threaded hole, and the bolt 1122 is threaded into the threaded hole. The end of the bolt 1122 abuts against the vertical bearing seat 111. The fixing plate 1121 is mounted on the fitness equipment support 120. The bolt 1122 abuts against the vertical bearing seat 111 in the radial direction.

[0094] In order to enable the connecting rod component 310 to be rotatably connected to the moving part 430, the rotatable follower part also includes a first joint bearing 320, and the connecting rod component 310 is connected to the moving part 430 through the first joint bearing 320.

[0095] During the movement of the moving part 430 driven by the two connecting rod components 310, the rotation between the connecting rod component 310 and the moving part 430 is achieved by connecting the two with a first joint bearing 320.

[0096] Specifically, the end of the connecting rod component 310 is threadedly connected to the first joint bearing 320.

[0097] In some embodiments of this application, the output terminal 220 may be an L-shaped plate.

[0098] The pedal end 210 includes a foot pedal 211, a rotating frame 212, and a leg pad 213. The leg pad 213 is connected to the foot pedal 211. The foot pedal 211 is connected to one end of the rotating frame 212, and the output end 220 is connected to the other end of the rotating frame 212. When the exerciser is stepping on the foot pedal 211, their legs are against the leg pad 213.

[0099] One end of the L-shaped plate is connected to the rotating frame 212, and the rotating shaft 230 is located at the connection between the L-shaped plate and the rotating frame 212.

[0100] The other end of the L-shaped plate is rotatably connected to the first joint bearing 320.

[0101] In order to limit the rotation angle of the pedal end 210 to the limit position, the fixing part also includes a second stop part 140. The second stop part 140 is disposed adjacent to the vertical bearing seat 111 and is used to limit the force-applying rotation part.

[0102] Specifically, the second stop 140 is used to limit the extreme position of the pedal end 210's rotation. When the pedal end 210 is rotated to the extreme position, the pedal end 210 abuts against the second stop 140.

[0103] In some embodiments of this application, the barbell moving part 400 further includes an adjustable counterweight part 410 and a rotating part 420. By adjusting the counterweight force at the adjustable counterweight part 410, the force applied to the connecting rod part 310 via the moving part 430 can be adjusted. When a fitness enthusiast steps on the foot pedal 211 and rests their legs against the leg pad 213, the force applied to the foot pedal 211 and leg pad 213 causes the rotating frame 212 to rotate. The rotating frame 212 must overcome the force transmitted to the moving part 430 to achieve the thigh abduction exercise.

[0104] Therefore, by adjusting the weight value at the adjustable weight unit 410, the force transmitted to the foot pedal 211 and leg pad 213 can be adjusted, thus adjusting the force that the fitness user can use to drive the foot pedal 211 and leg pad 213 to rotate. This makes it suitable for the needs of different fitness users.

[0105] The rotating end of the rotating part 420 is rotatably connected to the fitness equipment support part 120.

[0106] The extended end of the rotating part 420 is connected to the adjustable counterweight part 410, thereby achieving support for the adjustable counterweight part 410.

[0107] The end of the moving part 430 is connected to the middle of the rotating part 420, thereby transmitting the force transmitted to the moving part 430 to the rotating part 420. Since the force applied by the moving part 430 to the rotating part 420 acts on the middle of the rotating part 420, it can pull the rotating part 420 to rotate around the rotating end of the rotating part 420, thereby driving the adjustable counterweight 410 connected to the extension end of the rotating part 420 to rotate upward or downward.

[0108] Specifically, since the adjustable counterweight section 410 needs to be used to attach barbell plates, and the adjustable counterweight section 410 needs to have sufficient space for attaching barbell plates, the moving section 430 adopts a bent structure, extending upward from the moving section 430 to a certain height and connecting with the middle of the rotating section 420.

[0109] In some embodiments of this application, the adjustable counterweight 410 includes an extension 411 and a mounting portion 412. The middle portion of the extension 411 is connected to the extension end of the rotating portion 420. The mounting portion 412 is disposed on the fitness equipment support portion 120. An elastic band can be fitted over the extension 411 and the mounting portion 412, and a force is applied to the extension 411 by means of the elastic band.

[0110] Because the counterweight force of hanging barbell plates on the extension section 411 is relatively large, the load is too heavy for lighter fitness enthusiasts who are beginners in thigh abduction exercises. Therefore, by adding elastic bands to the extension section 411 and the hanging section 412, the applicability of the fitness equipment is broadened, thereby improving the user experience for a wider range of users.

[0111] Specifically, the attachment part 412 includes a support post 4121 and a first stop part 4122. One end of the support post 4121 is connected to the fitness equipment support part 120. The first stop part 4122 is connected to the other end of the support post 4121. When the elastic band is fitted onto the support post 4121, the first stop part 4122 is used to stop the elastic band and prevent it from falling off the support post 4121.

[0112] In some embodiments of this application, in order to prevent the barbell plates attached to the extension 411 from falling off, the height from the middle of the extension 411 to the end of the extension 411 is increased.

[0113] Since the rotating end of the rotating part 420 is rotatably connected to the fitness equipment support part 120, and the extended end of the rotating part 420 is extended, and an adjustable counterweight part 410 is connected to the extended end of the rotating part 420, the adjustable counterweight part 410 also includes an original position support part 413, which is provided on the fitness equipment support part 120 below the extended end of the rotating part 420. When the moving part 430 does not apply force to the rotating part 420, the middle part of the extended part 411 abuts against the original position support part 413.

[0114] In some embodiments of this application, since there is rotation between the connecting rod component 310 and the moving part 430 during the process of the connecting rod component 310 pulling the moving part 430, the connecting rod component 310 and the moving part 430 are connected by the second joint bearing 431.

[0115] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0116] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0117] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
