In the description of the present disclosure, a plurality of means two or more unless otherwise specified.

[0027] In the description of the present disclosure, it should be noted that, unless otherwise explicitly specified and defined, the terms installation, connected, and connection should be interpreted broadly. For example, the terms can mean fixed connections, detachable connections, integral connections, mechanical connections or electrical connections, direct connections or indirect connections through intermedia, or connections within two elements. For those ordinary skills in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0028] A specific structure of a power meter applied at the rowing machine of the embodiments of the present disclosure is described below with reference to FIGS. 3 to 5.

[0029] The present disclosure provides a power meter applied at a rowing machine (hereinafter referred to as a power meter). As shown in FIG. 1, the rowing machine includes a tension assembly 100. One end of the tension assembly 100 is connected to a weight, and the other end is for the user to hold. As shown in FIGS. 3 to 5, the power meter of the present disclosure includes a housing 200, a fixation assembly, and a tension detection device 400. The fixation assembly is arranged at two ends of the housing 200. The tension detection device 400 is arranged inside the housing 200 and is connected to the fixation assembly. The tension detection device is configured to detect the tension applied to the fixation assembly. The tension assembly 100 includes two mechanical coupling members 110. The fixation assembly is detachably connected to the two mechanical coupling members 110 to cause a part of the tension assembly 100 between the two mechanical coupling members 110 to be in a relaxed state.

[0030] Firstly, it should be noted that the tension detection device 400 can be inside the housing 200 and connected to the fixation assembly. In some embodiments, the fixation assembly can extend into the housing 200 and be connected to the tension detection device 400. In other embodiments, two ends of the tension detection device 400 can extend into the housing 200 and be connected to the fixation assembly. In some embodiments, the fixation assembly can be attached to an outer sidewall of the housing 200, and the tension detection device 400 can be attached to an inner sidewall of the housing 200. The fixation assembly and the tension detection device 400 can be connected through an intermediate connection piece passing through the housing 200. The connection method between the tension detection device 400 and the fixation assembly can be selected according to actual needs.

[0031] It is to be understood that, since the fixation assembly of the power meter of the present disclosure is detachably connected to the tension assembly 100 and is not connected to the end of the tension assembly 100 held by the user, the power meter can be connected to any position in the middle of the tension assembly 100 through the fixation assembly during actual use to make the power meter applicable to various types of rowing machines. Meanwhile, the power meter only includes the housing 200, the fixation assembly, and the tension detection device 400. The structure of the power meter is simple, and the manufacturing cost of the power meter is low.

[0032] FIG. 2 is a schematic diagram showing an operation principle of the power meter. In practical applications, the power meter is connected to the tension assembly 100 through the fixation assembly. The part of the tension assembly 100 connected to the fixation assembly is a mechanical coupling member 110. Since the part of the tension assembly 100 between two mechanical coupling members 110 is in the relaxed state, when the user pulls the tension assembly 100 for training, the mechanical coupling member 110 close to the user can apply a pulling force towards the user at the fixation assembly. The mechanical coupling member 110 close to the weight can also apply a pulling force towards the weight at the fixation assembly. Since the fixation assembly is connected between two ends of a tension sensor, the two ends of the tension sensor can be subjected to pulling forces in two directions to detect the pulling force of the user. The detection can be used to directly detect the pulling force applied by the user with a relatively high detection precision.

[0033] It should be added that the tension detection device 400 can include a built-in wireless communication module, which is connected to a user smart wearable apparatus or an intelligent display screen of the rowing machine. Thus, the user can obtain the size of the pulling force detected by the tension detection device 400 in real-time and accurately. Of course, a small display screen can also be arranged at the housing 200, can be directly electrically connected to the tension detection device 400, and can be configured to display the detection value of the tension detection device 400.

[0034] In some embodiments, as shown in FIGS. 3 to 5, the fixation assembly includes two fixation sub-members 300, which are arranged at the two ends of the tension detection device 400, respectively, and the two ends of the tension detection device 400 are mechanically coupled with the two fixation sub-members 300. It can be understood that by using the fixation sub-members 300 as the ends of the tension detection device 400 to be connected to the mechanical coupling members 110 of the tension assembly 100, on one aspect, the power meter can be facilitated to be mounted at the tension assembly 100, and the application of the power meter can be facilitated. On another aspect, the tension detection device 400 and the tension assembly 100 can be ensured to be stably connected, and the tension detection device 400 can be ensured to detect the pulling force applied by the user at the tension assembly 100.

[0035] Further, it needs to be noted that a plurality of methods can be provided for the two ends of the tension detection device 400 to be mechanically coupled with the two fixation sub-members 300. In some embodiments, the two ends of the tension detection device 400 can be connected to the fixation sub-members through screws, pins, or rivets. In other embodiments, the two ends of the tension detection device 400 can be directly welded or glued to the fixation sub-members 300. In some other embodiments, the tension detection device 400 can be connected to the fixation sub-members 300 via structures like clips. The specific connection method can be selected according to actual needs.

[0036] In some embodiments, as shown in FIGS. 3 and 4, each fixation sub-member 300 includes a first fixation plate 310 and a press plate 320. The first fixation plate 310 is connected to an end of the tension detection device 400, and the press plate 320 is connected to the first fixation plate 310. The mechanical coupling member 110 is clamped between the first fixation plate 310 and the press plate 320. It can be understood that during the actual assembly process, the first fixation plate 310 can be first connected to the tension detection device 400, the tension assembly 100 can be then arranged at the first fixation plate 310, and the press plate 320 can be finally mounted at the first fixation plate 310 to clamp the mechanical coupling member 110 between the first fixation plate 310 and the press plate 320. The mounting method is very simple and facilitates the installation and removal of the power meter.

[0037] In some embodiments, as shown in FIGS. 3 and 4, the fixation sub-member 300 also includes a lock member 330. The lock member 330 passes through the first fixation plate 310 and the press plate 320 and is configured to cause the press plate 320 to clamp the mechanical coupling member 110 at the first fixation plate 310. It can be understood that during the actual measurement process if the mechanical coupling member 110 moves relative to the fixation sub-member 300, the detection precision of the tension detection device 400 can be lowered. In some embodiments, by adding the lock member 330, the mechanical coupling member 110 can be tightly clamped between the first fixation plate 310 and the press plate 320, which prevents the mechanical coupling member 110 from moving relative to the fixation sub-member 300 and ensures the detection precision of the tension detection device 400.

[0038] In some embodiments, the lock member 330 can be a screw. Therefore, in actual operation, a pressing degree of the press plate 320 to the mechanical coupling member 110 can be adjusted by only rotating the screw. The operation is simple. Of course, in some other embodiments of the present disclosure, the lock member 330 can be selected according to actual needs.

[0039] In some embodiments, as shown in FIGS. 3 and 4, two lock members 330 are provided. The two lock members 330 are arranged on two sides of the mechanical coupling member 110. It can be understood that with the two lock members 330, the mechanical coupling member 110 can be tightly clamped between the first fixation plate 310 and the press plate 320 maximally, which prevents the mechanical coupling member 110 from moving relative to the fixation sub-members 300 and ensures the detection precision of the tension detection device 400.

[0040] It needs to be noted that, in other embodiments of the present disclosure, a fixing pin can be arranged at one of the first fixation plate 310 and the press plate 320, and a fixing hole cooperating with the fixing pin can be provided at the other one of the first fixation plate 310 and the press plate 320. The fixing pin can be a conical post. Thus, without the lock member 330, the mechanical coupling member 110 can be clamped between the first fixation plate 310 and the press plate 320. That is, in some other embodiments of the present disclosure, the connection method between the first fixation plate 310 and the press plate 320 can be selected according to the actual needs and is not limited to the technical solution with the lock member 330.

[0041] In some embodiments, as shown in FIGS. 3 and 4, the fixation sub-member 300 includes a first winding member 340. The first winding member 340 cooperates with the mechanical coupling member 110. The mechanical coupling member 110 can be wounded at least one turn around the first winding member 340. It can be understood that during the actual measurement process if the mechanical coupling member 110 moves relative to the fixation sub-members 300, the detection precision of the tension detection device 400 can be lowered. According to the detection principle, when the connection of the mechanical coupling member 110 is more stable relative to the fixation sub-members 300, the detection precision can be higher. In some embodiments, after the mechanical coupling member 110 is wounded at least one turn at the first winding member 340, the mechanical coupling member 110 can be fixed at the fixation sub-members 300 and cannot move relative to the fixation sub-members 300. Thus, the detection precision of the tension detection device 400 can be maximally ensured.

[0042] In some embodiments, as shown in FIG. 5, the fixation sub-member 300 includes a second fixation plate 350. The second fixation plate 350 is connected to the end of the tension detection device 400. The second fixation plate 350 includes a fitting groove 351. One end of the fitting groove 351 is open, and the mechanical coupling member 110 passes through the fitting groove 351 and is clamped in the fitting groove 351 by a press member 360 passing through the second fixation plate 350. It can be understood that during actual operation, the mechanical coupling member 110 can be fixed at the second fixation plate 350 by only passing the mechanical coupling member 110 through the open end of the fitting groove 351. Then, the mechanical coupling member 110 can be clamped in the fitting groove 351 through the press member 360 passing through the second press plate 350. Thus, the installation is convenient.

[0043] In some embodiments, as shown in FIG. 5, the second fixation plate 350 also includes a second winding member 370. The mechanical coupling member 110 passes through the fitting groove 351 and is wounded at the second winding member 370. In the actual detection process, if the mechanical coupling member 110 moves relative to the second fixation plate 350, the detection precision of the tension detection device 400 can be lowered. According to the detection principle, when the connection of the mechanical coupling member 110 is more stable relative to the second fixation plate 350, the detection precision can be higher. In some embodiments, after the mechanical coupling member 110 is wounded at least one turn at the second winding member 370, the mechanical coupling member 110 can be fixed at the second fixation plate 350 and cannot move relative to the second fixation plate 350, Thus, the detection precision of the tension detection device 400 can be maximally ensured.

[0044] In some embodiments, a distance detection device can be also provided inside the housing 200. It can be understood that during actual operation, the distance detection device can be configured to detect the displacement of the housing 200. Thus, the power meter of the present disclosure can detect the pulling force and the position of the tension assembly 100, which improves the user experience.
