The rowing machine is a machine used for training purposes to simulate water rowing sports. The rowing machine usually includes a base and a tension component arranged on the base, one end of the tension component is connected to a weight, and the other end is for the user to hold. During the training process, the user sits on the base, holds one end of the tension component, and continuously lifts and lowers the other end of the tension component to achieve the effect of training muscle groups. In order to achieve refined management, the tension applied by the user to the tension component needs to be tested during the training process. However, most of the rowing machines in the prior art are not equipped with a dedicated power meter and cannot detect the tension applied by the user to the tension component. A small number of rowing machines are provided with a power handle at one end of the tension component for the user to hold, but the manufacturing cost of the power handle is relatively high, and it can only be applied to a small number of rowing machines, and is not applicable to rowing machines that have been provided with non-detachable handles.

[0033] Reference below Figure 3-Figure 5 Describe the specific structure of the power meter for the rowing machine according to the embodiment of the present invention

[0034] The present invention discloses a power meter for a rowing machine (hereinafter referred to as a power meter), such as Figure 1 As shown, the rowing machine has a tension assembly 100, one end of which is connected to a weight, and the other end is for a user to hold. Figure 3-Figure 5As shown, the power meter disclosed in the present invention includes a housing 200, a fixing assembly and a tension detection device 400. The fixing assemblies are arranged at both ends of the housing 200. The tension detection device 400 is arranged inside the housing 200 and connected to the fixing assembly. The tension detection device is used to detect the tension acting on the fixing assembly. The tension assembly 100 includes two mechanical coupling parts 110. The fixing assembly is detachably connected to the two mechanical coupling parts 110, respectively, so that a part of the tension assembly 100 between the two mechanical coupling parts 110 is in a relaxed state.

[0035] First of all, it should be explained that since the tension detection device 400 is inside the shell 200 and is connected to the fixed component, in some embodiments, the fixed component extends into the shell 200 and is connected to the tension detection device 400; in some embodiments, both ends of the tension detection device 400 extend into the shell 200 and are connected to the fixed component; in some embodiments, the fixed component is attached to the outer wall of the shell 200, and the tension detection device 400 is attached to the inner wall of the shell 200, and the fixed component and the tension detection device 400 are connected by an intermediate connecting piece passing through the shell 200, and the connection method between the tension detection device 400 and the fixed component can be selected according to actual needs.

[0036] It is understandable that, since the fixing assembly of the power meter of the present invention is detachably connected to the tension assembly 100 and is not connected to the end of the tension assembly 100 for the user to hold, in actual use, the power meter can be connected to any position in the middle of the tension assembly 100 through the fixing assembly, so that the power meter can be applied to various types of rowing machines. At the same time, the power meter only includes a housing 200, a fixing assembly and a tension detection device 400, and has a very simple structure and a low manufacturing cost.

[0037] The measuring principle of the power meter of the present invention is as follows Figure 2 As shown, in actual use, the power machine is connected to the tension component 100 through a fixed component, and the part connecting the tension component 100 and the fixed component is a mechanical coupling part 110. Since the part of the tension component 100 between the two mechanical coupling parts 110 is in a relaxed state, when the user pulls the tension component 100 for training, the mechanical coupling part 110 close to the user will apply a pulling force toward the user to the fixed component, and the mechanical coupling part 110 close to the weight will also apply a pulling force toward the weight to the fixed component. Since the fixed component is connected to both ends of the tension sensor, the two ends of the tension sensor can be subjected to tension in two directions, thereby realizing the detection of the user's tension. This detection can directly measure the tension applied by the user, and the measurement accuracy is relatively high.

[0038] It should be noted that the tension detection device 400 can have a built-in wireless communication module and be connected to the user's smart wearable device or the smart display screen of the rowing machine, so that the user can obtain the tension measured by the tension detection device 400 in real time and accurately. Of course, a small display screen can also be set on the housing 200, which is directly electrically connected to the tension detection device 400 and is used to display the detection value of the tension detection device 400.

[0039] In some embodiments, Figure 3-Figure 5 As shown, the fixing assembly includes two fixing elements 300, which are respectively arranged at the two ends of the tension detection device 400, and the two ends of the tension detection device 400 are respectively mechanically coupled with the two fixing elements 300. It can be understood that, by connecting the fixing elements 300 as the ends of the tension detection device 400 with the mechanical coupling part 110 of the tension assembly 100, on the one hand, it is convenient to install the entire power meter on the tension assembly 100, and to facilitate the use of the power meter, and on the other hand, it ensures that the tension detection device 400 can be stably connected to the tension assembly 100, and ensures that the tension detection device 400 can stably detect the tension applied by the user on the tension assembly 100.

[0040] It should be additionally explained that there are multiple ways to mechanically couple the two ends of the tension detection device 400 with the two fixed sub-elements 300 respectively. In some embodiments, the two ends of the tension detection device 400 are connected to the fixed sub-elements 300 by connecting parts such as screws, pins or rivets; in some embodiments, the two ends of the tension detection device 400 are directly welded or bonded to the fixed sub-elements 300; in some embodiments, the tension detection device 400 can also be connected to the fixed sub-elements 300 by structures such as snaps. The specific connection method can be selected according to actual needs.

[0041] In some embodiments, Figure 3-Figure 4 As shown, each fixing sub-element 300 includes a first fixing plate 310 and a clamping plate 320, the first fixing plate 310 is connected to the end of the tension detection device 400, the clamping plate 320 is connected to the first fixing plate 310, and the mechanical coupling part 110 is clamped between the first fixing plate 310 and the clamping plate 320. It can be understood that in the actual assembly process, the first fixing plate 310 is first connected to the tension detection device 400, and then the tension assembly 100 is placed on the first fixing plate 310, and finally the clamping plate 320 is installed on the first fixing plate 310 and the mechanical coupling part 110 is clamped between the first fixing plate 310 and the clamping plate 320. Such an installation method is very simple and convenient for the installation and disassembly of the power meter.

[0042] In some embodiments, Figure 3-Figure 4As shown, the fixing element 300 further includes a locking member 330, which is provided through the first fixing plate 310 and the pressing plate 320, and is used to enable the pressing plate 320 to press the mechanical coupling part 110 against the first fixing plate 310. It can be understood that in the actual measurement process, if the mechanical coupling part 110 moves relative to the fixing element 300, the detection accuracy of the tension detection device 400 will be reduced. In this embodiment, the mechanical coupling part 110 is firmly pressed between the first fixing plate 310 and the pressing plate 320 by the additional locking member 330, thereby avoiding the mechanical coupling part 110 from moving relative to the fixing element 300, and ensuring the detection accuracy of the tension detection device 400.

[0043] Optionally, the locking member 330 is a screw. Therefore, in the actual working process, only the screw needs to be turned to adjust the degree of compression of the clamping plate 320 on the mechanical coupling part 110, which is very convenient to operate. Of course, in other embodiments of the present invention, the locking member 330 can also be selected according to actual needs.

[0044] In some specific embodiments, Figure 3-Figure 4 As shown, there are two locking members 330, and the two locking members 330 are located on both sides of the mechanical coupling part 110. It can be understood that, through the locking of the two locking members 330, the mechanical coupling part 110 can be firmly pressed between the first fixing plate 310 and the pressing plate 320 to the greatest extent, thereby preventing the mechanical coupling part 110 from moving relative to the fixing sub-element 300, and ensuring the detection accuracy of the tension detection device 400.

[0045] It should be additionally explained here that, in other embodiments of the present invention, one of the first fixing plate 310 and the pressing plate 320 is provided with a fixing pin, and the other is provided with a fixing hole that cooperates with the fixing pin, and the fixing pin is a tapered pin, so that the mechanical coupling part 110 can be pressed between the first fixing plate 310 and the pressing plate 320 without the locking member 330. That is to say, in other embodiments of the present invention, the connection method of the first fixing plate 310 and the pressing plate 320 can be selected according to actual needs, and is not limited to the technical solution of locking with the locking member 330 described above.

[0046] In some specific embodiments, Figure 3-Figure 4As shown, the fixed sub-element 300 includes a first winding portion 340, and the first winding portion 340 cooperates with the mechanical coupling portion 110, and the mechanical coupling portion 110 is wound at least once on the first winding portion 340. It can be understood that in the actual measurement process, if the mechanical coupling portion 110 moves relative to the fixed sub-element 300, the detection accuracy of the tension detection device 400 will be reduced, and according to the measurement principle, the better the connection stability of the mechanical coupling portion 110 relative to the fixed sub-element 300, the higher the measurement accuracy. In this embodiment, after the mechanical coupling portion 110 is wound at least once on the first winding portion 340, the mechanical coupling portion 110 is fixed on the fixed sub-element 300, and it is impossible to move relative to the fixed sub-element 300, thereby maximizing the measurement accuracy of the tension detection device 400.

[0047] In some specific embodiments, Figure 5 As shown, the fixing element 300 includes a second fixing plate 350, which is connected to the end of the tension detection device 400. The second fixing plate 350 is provided with a matching groove 351, one end of which is open, and the mechanical coupling part 110 is arranged through the matching groove 351, and is pressed in the matching groove 351 by a pressing member 360 provided on the second fixing plate 350. It can be understood that in the actual working process, the mechanical coupling part 110 only needs to be passed through the open end of the matching groove 351 to fix the mechanical coupling part 110 on the second fixing plate 350, and then pressed in the matching groove 351 by the pressing member 360 provided on the second fixing plate 350, which is very convenient to install.

[0048] In some specific embodiments, Figure 5 As shown, the second fixed plate 350 is also provided with a second winding portion 370, and the mechanical coupling portion 110 is arranged through the matching groove 351 and wound on the second winding portion 370. In the actual measurement process, if the mechanical coupling portion 110 moves relative to the second fixed plate 350, the detection accuracy of the tension detection device 400 will be reduced, and according to the measurement principle, the better the connection stability of the mechanical coupling portion 110 relative to the second fixed plate 350, the higher the measurement accuracy. In this embodiment, after the mechanical coupling portion 110 is wound on the second winding portion 370 for at least one circle, the mechanical coupling portion 110 is fixed on the second fixed plate 350, and it is impossible to move relative to the second fixed plate 350, thereby maximally ensuring the measurement accuracy of the tension detection device 400.

[0049] In some embodiments, a distance detection device is further provided in the housing 200. It is understandable that in actual operation, the distance detection device can also detect the displacement of the housing 200, so that the power meter of the present invention can detect the position of the tension component 100 while detecting the tension, thereby improving the user experience.
