Detailed implementation manner

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0035] As Figures 1 to 10 shown, the present invention provides a treadmill with rowing function, including: a base 100, which is the exercise area of the treadmill and includes structures such as a base, a running belt 110, and a power source. In addition, the base 100 is preferably set as a foldable structure, which can further reduce the space occupation and is convenient for storage; it should be noted that setting the base 100 as a non - foldable state is also within the protection scope of the present invention.

[0036] The armrest mechanism 200 is rotatably arranged on the base 100 and has a retracted state and an extended state. When using the running function, the armrest mechanism 200 needs to be rotated to the extended state, and when using the rowing function, the armrest mechanism 200 can be rotated to the retracted state. The rotation of the armrest mechanism 200 can be set as manual rotation or electric rotation. When set as electric rotation, a driving source such as a driving motor needs to be added. The armrest mechanism 200 includes a support assembly and a rowing assembly. The support assembly further includes a support frame 230 and a column 220. The support frame 230 is hinged to the base 100 to realize the rotation function of the armrest mechanism 200. The column 220 is slidably connected to the support frame 230 and can slide on the support frame 230 along its length direction. It should be noted that the number of columns 220 can be one or more. When there are multiple columns 220, all the columns 220 are slidably connected to the support frame 230, and at the same time, the slide seat 210 is also slidably connected to all the columns 220.

[0037] Among them, the rowing component further includes a sliding seat 210, a pulling handle 250 and a spring-back component. The pulling handle 250 is connected to the support frame 230 through the spring-back component; the spring-back component is a resistance component of the rowing mechanism, and its output end is detachably connected to the pulling handle 250. When the user pulls the pulling handle 250, it is necessary to overcome the resistance provided by the spring-back component in the direction opposite to the direction of pulling the pulling handle 250; if necessary, the pulling handle 250 can be connected to the spring-back device through a traction structure such as a traction rope. The sliding seat 210 is slidably arranged on the column 220 along the length direction of the column 220, and when the armrest mechanism 200 rotates to the retracted state, the support component provides support for the sliding seat 210. It should be noted that the support for the sliding seat 210 means that when the user uses the rowing function, the support component can support the sliding seat 210 so that the sliding seat 210 can carry the user. Specifically, when the user sits on the sliding seat 210, he drives the sliding seat 210 to slide back and forth along the length direction of the column 220 through the strength of the buttocks, so as to simulate the rowing action. In the present utility model, both the column 220 and the support frame 230 and the column 220 and the sliding seat 210 are slidably connected, effectively increasing the limit distance of the sliding of the sliding seat 210 and fully meeting the fitness needs of different people. In the running state, the runner can adjust the armrest 281 to a suitable height according to his own height; in the rowing state, the user can adjust the front and rear positions of the sliding seat 210 according to the actual fitness needs.

[0038] As Figure 1 , Figure 2 and Figure 4 shown, in some embodiments, the rowing component further includes a foot pedal 260, which is hinged to the support frame 230 and is located at one end of the support frame 230 hinged to the base 100 and can rotate relative to the support frame 230. When it is necessary to use, rotate the foot pedal 260 to a predetermined position, and when using the running function, rotate it to a position that does not affect the running function. It should be noted that the foot pedal 260 can also be arranged on the base 100.

[0039] As Figures 1 to 3 , Figure 8As shown, in some embodiments, the armrest mechanism 200 is further provided with two armrests 281. When the armrest mechanism 200 is in the unfolded state, the support assembly provides usage support for the armrests 281. When the user uses the running function, the armrests 281 can provide support force for the user himself, that is, the support assembly bears the armrests 281, thereby providing usage support force for the user. Specifically, a first support beam 280 is provided at one end of the column 220 away from the support frame 230, and armrests 281 are fixedly provided at both ends of the first support beam 280. When the armrest mechanism 200 rotates to the retracted state, the ends of the two armrests 281 are in contact with the ground, forming a first support point, which together with the support assembly provides usage support for the sliding seat 210. Specifically, support portions 233 are provided on both sides of the support frame 230. When the armrest mechanism 200 rotates to the retracted state, the support portions 233 form a second support point, and the first support point and the second support point jointly act to provide stable support for the column 220. In addition, when using the rowing function, after the user sits on the sliding seat 210, the friction between the armrest 281 and the ground increases, which can effectively prevent the column 220 from displacing during movement and enhance the running stability of the treadmill during fitness. It should be noted that the first support beam 280, the second support beam 236, the first support point and the second support point are only aliases for convenience of description, and do not refer to specific structures and quantities, and the protection scope of the present invention cannot be limited thereby.

[0040] When using the rowing function, the main function of the armrest 281 is to provide support for the column 220. Therefore, when the armrest mechanism 200 rotates to the retracted state, the armrest 281 is arranged to abut against the base frame 120 on both sides of the running belt 110, and the present invention can also be realized. It can be understood that the support portion 233 can also be arranged in this way.

[0041] As Figures 1 to 3 、 Figure 8 As shown, in some embodiments, the support frame 230 further includes a second support beam 236, and an installation portion is provided on the second support beam 236. A slide rail is provided on the column 220, and a pulley is correspondingly provided on the installation portion. The slide rail and the pulley cooperate with each other to realize the sliding connection between the column 220 and the support frame 230. In addition, the sliding connection between the column 220 and the support frame 230 can also be realized by structures such as a slide rail and a slider that cooperate with each other. For example, a slider fixedly provided on the installation portion and a slide rail provided on the column 220 in cooperation.

[0042] It should be noted that the structure of the slide rail can be a rectangular chute or an arc-shaped chute, but is not limited thereto, and can be specifically set according to actual needs; in addition, the number of slide rails can be one or more, and the present invention can be realized.

[0043] As Figures 2 to 7As shown, in some embodiments, the installation part includes a locking component, which can be a bolt locking structure, a clamping structure, or a pin and socket structure that cooperate with each other and can lock the relative positions of the upright column 220 and the support frame 230. Multiple locking structures can also be used simultaneously to increase the locking stability and make the fitness equipment operate more stably during the movement process.

[0044] When using the rowing function, the user adjusts the front and rear positions of the upright column 220 according to their own height and fitness needs, and then locks the upright column 220 through the locking component to prevent the upright column 220 from shifting during use as the sliding seat 210 slides, improving the operating stability of the fitness equipment. In addition, during running, the user can also adjust the height of the armrest mechanism 200 according to their own needs.

[0045] As Figures 2 to 3 shown, in some embodiments, the locking component includes a locking screw 231 fixedly arranged on the installation part. Specifically, a through threaded hole is provided on the installation part, and the locking screw 231 is screwed into the threaded hole. In the locked state, the locking screw 231 passes through the threaded hole and its end abuts against the surface of the upright column 220 to lock the upright column 220. It should be noted that the locking screw 231 can be set to one or multiple.

[0046] As Figures 3 to 7 shown, in some embodiments, the locking component includes a positioning pin 232 arranged on the installation part, and a number of positioning holes 221 corresponding to the positioning pin 232 are provided on the upright column 220. The number of positioning holes 221 are spaced along the length direction of the upright column 220. After the upright column 220 is adjusted to a predetermined position, the positioning pin 232 is inserted into the positioning hole 221, and the two cooperate with each other to lock the relative positions of the upright column 220 and the support frame 230, avoiding the upright column 220 from sliding with the sliding seat 210 during the movement process and causing displacement.

[0047] As Figures 4 to 6 shown, preferably, the positioning pin 232 is an elastic positioning pin 232, and when the upright column 220 slides to the limit position relative to the support seat, a positioning hole 221 is provided on the upright column 220 at a position corresponding to the elastic positioning pin 232. After the upright column 220 slides to its sliding limit position, the elastic positioning pin 232 is inserted into the positioning hole 221 under the drive of the elastic member 2321 to achieve the locking function, which can effectively prevent the upright column 220 and the support frame 230 from separating from each other due to excessive sliding force or external force influence.

[0048] In this embodiment, the elastic positioning pin 232 further has a locking end 2322, and the locking end 2322 is further set to a hemispherical or arc-shaped structure. After the column 220 slides to the corresponding position, the hemispherical structure of the locking end 2322 is inserted into the positioning hole 221 to lock its position. If the sliding force of the column 220 is further increased, the arc-shaped structure of the locking end 2322 is stressed, and the elastic member 2321 on the elastic positioning pin is compressed, and the locking end 2322 slides out of the positioning hole 221 to release the lock. Such a setting can adjust the locking force by setting the magnitude of the spring force, and it is also extremely convenient to use.

[0049] As Figures 1 to 6 , Figures 8 to 9 shown, in the present utility model, the resilience structure is set as an elastic band 240. One end of the elastic band 240 is detachably connected to the support frame 230, and the other end is detachably connected to the pull handle 250. Through the detachable connection structure, the maintenance and replacement of the elastic band 240 are facilitated. The detachable structure can adopt a clamping structure, an opening groove, a pin 252 structure that cooperates with each other, a screw, etc. For example, it can be a clamping head having a first clamping portion and a second clamping portion, and the elastic band 240 is clamped by the cooperation of the first clamping portion and the second clamping portion; or a screw connected by threads, and the elastic band 240 is sleeved on the screw to fix the elastic band 240. It should be noted that the elastic band 240 can be fixed by using one of the above structures, or multiple structures can be combined to fix the elastic band 240 at the same time. For example, the opening groove and the screw that cooperate with each other are used to achieve locking.

[0050] During the use process, the user can select an elastic band 240 with a suitable elastic coefficient or a suitable length according to their own height, strength and fitness needs for practice. The structure is simple, the cost is low, and the practicability is high, and the maintenance is also extremely convenient. Among them, the number of elastic bands 240 can be set to one or more. When multiple elastic bands are set, the user needs to select a suitable number according to their actual situation to achieve the effect of adjusting the training intensity.

[0051] In some embodiments, the resilience component can also adopt other resistance structures such as a scroll spring, an internal magnetic control flywheel group, etc. that can achieve the resilience function.

[0052] As Figures 3 to 6 , Figure 8 , Figure 9As shown, in some embodiments, a first opening groove 237 is provided on the support frame 230, a second opening groove 251 is provided on the pull handle 250, and a pin 252 is provided in both the first opening groove 237 and the second opening groove 251; and preferably, the opening sizes of the first opening groove 237 and the second opening groove 251 are both less than or equal to the diameter of the pin 252. One end of the elastic band 240 is fixed in the first opening groove 237 through the pin 252, and the other end is fixed in the second opening groove 251 through the pin 252. When the elastic band 240 needs to be replaced, the pin 252 can be taken out to remove the elastic band 240, and the disassembly and installation of the elastic band 240 can be quickly realized. It should be noted that the first opening groove 237 and the second opening groove 251 can be rectangular, circular or arc-shaped structures, as long as the quick disassembly and installation of the elastic band 240 can be realized.

[0053] As Figure 3 , Figure 9 shown, in this embodiment, both the first opening groove 237 and the second opening groove 251 have a cylindrical groove body, the groove body has a first opening 2371 and a second opening 2372, and a threaded hole is provided at the other end of the groove body corresponding to the first opening 2371. The pin 252 is a bolt, one end of the bolt has a nut, and the other end is provided with a thread that matches the threaded hole. The elastic band 240 is sleeved on the bolt, and the bolt is screwed into the threaded hole, and the elastic band 240 extends out from the second opening 2372, so as to realize the fixing of the elastic band 240.

[0054] As Figures 1 to 5 , Figure 8 , Figure 10 shown, in some embodiments, the rowing assembly further includes a limit seat 270. The limit seat 270 can serve as a force-bearing fulcrum for the elastic band 240 and provide a guiding function for the elastic band 240. Preferably, it is arranged near the pull handle 250 along the stretching direction of the elastic band 240. It can be an annular structure, a hole or other structures that can allow the elastic band 240 to pass through and provide a force-bearing fulcrum; for example, a smooth-surfaced circular ring or rectangular ring, or a limit block with a rectangular through hole. The contact surface of the elastic band 240 is set as a smooth surface to reduce the friction force between the limit seat 270 and the elastic band 240, which can effectively extend the service life of the elastic band 240.

[0055] Specifically, the support frame 230 has a first end 234 and a second end 235 that face away from each other along the sliding direction of the column 220. The end of the support frame 230 hinged to the base 100 is the first end 234, and the other end away from the first end 234 is the second end 235. The limit seat 270 is arranged on the first end 234; one end of the elastic band 240 is arranged on the second end 235, and the other end passes through the limit seat 270 and is connected to the pull handle 250. When the rowing function is not in use, the pull handle 250 remains in contact with the limit seat 270 under the contraction elastic force of the elastic band 240. With this setting, during the exercise process, the elastic band 240 can always provide a rebound elastic force to the pull handle 250, improving the fitness effect. Moreover, when the treadmill is in the storage and folding state or the running state, the pull handle 250 can be prevented from shaking due to the movement or vibration of the treadmill.

[0056] As Figure 2 , Figure 5 , Figure 10 shown, in some embodiments, the limit seat 270 includes two rotating rollers 271 arranged in parallel. Both of the two rotating rollers 271 are rotatably arranged on the mounting seat 272 through rotating shafts, and the axes of the two rotating rollers 271 are perpendicular to the stretching direction of the elastic band 240. The elastic band 240 is arranged to pass between the two rotating rollers 271. During the stretching process of the elastic band 240, the rotating rollers 271 rotate along with the stretching of the elastic band 240, effectively reducing the friction force between the elastic band 240 and the limit seat 270 and prolonging the service life of the elastic band 240; at the same time, the force on the elastic band 240 is more uniform and the use is smoother.

[0057] The above further describes the present invention with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the present invention. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present invention.
