Description
Technical Field
[0001] The utility model relates to the field of measuring tools, in particular to an intelligent measuring tape and a digital acquisition device for fitness equipment training. Background Art
[0002] In the comprehensive strength training equipment of the fitness industry, the current training weight used, how many times the weight is used for training, how often the training is done, the power or consumption, etc. are very important training information for strength training. Therefore, it is necessary to digitize the current training content of the user.
[0003] In the related technology, there are four solutions for digitizing strength training equipment: laser, grating, reed switch and gyroscope, but all four solutions have limitations. For example, the cost of the laser solution is high, the light has a great impact, the service life is short, the movement speed cannot be too fast, and the verticality of the installation is high. The cost of the grating solution is even higher, and the power supply requirements are more stringent, which is not conducive to some scenarios that can only be powered by batteries.

[0050] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to that described herein.
[0051] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.
[0052] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.
[0053] See also Figures 1 to 5 The smart measuring tape provided by one embodiment of the utility model includes a housing 1, a turntable 2, a rope collection mechanism, a measuring tape 20 and a data acquisition module.
[0054] The housing 1 is provided with a rope outlet 13. The turntable 2 is rotatably disposed in the housing 1. The rope collecting mechanism is disposed in the turntable 2, and the rope collecting mechanism drives the turntable 2 to rotate in the forward direction. The ruler rope 20 is wound outside the turntable 2, and the inner end of the ruler rope 20 is connected to the turntable 2. The ruler rope 20 can be collected under the driving force provided by the rope collecting mechanism, and the outer end of the ruler rope 20 extends out of the rope outlet 13. The data acquisition module is used to detect the angle change of the turntable 2, and to count the number of times the turntable 2 changes from forward rotation to reverse rotation or from reverse rotation to forward rotation.
[0055] Through the above structural design, when the ruler rope 20 is subjected to external force and overcomes the driving force of the rope collection mechanism to release the rope, the ruler rope 20 can drive the turntable 2 to rotate in the opposite direction. When the ruler rope 20 is subjected to the driving force of the rope collection mechanism to collect the rope, the rope collection mechanism can drive the turntable 2 to rotate in the forward direction. In other words, the angle of the turntable 2 changes during the process of collecting and releasing the ruler rope 20. By detecting the angle change of the turntable 2 through the data acquisition module, the length change of the ruler rope 20 can be obtained.
[0056] When the smart tape measure is used on strength training equipment, the housing 1 can be connected to the frame 100 of the strength training equipment, and the outer end of the ruler rope 20 is connected to the moving part 200 that can move relative to the frame 100. The weight information of the moving part 200 can be obtained by detecting the angle change of the turntable 2 through the data acquisition module to obtain the length change of the ruler rope 20. The number of times the turntable 2 changes from forward rotation to reverse rotation or from reverse rotation to forward rotation is obtained by counting the number of times the ruler rope 20 changes from contraction to release or from release to collection to obtain the number of times the moving part 200 moves. There is no need to modify the strength training equipment, which reduces the cost of use, and the sports training data of interest can be accurately measured.
[0057] The data acquisition module includes a magnetic member 3 and a sensor 4. The magnetic member 3 is arranged in the housing 1 and can rotate coaxially with the turntable 2. The adjacent magnetic poles along the circumferential direction of the magnetic member 3 are alternately different. The sensor 4 is arranged in the housing 1 and at one end of the axial direction of the magnetic member 3. The sensor 4 detects the angle change of the magnetic member 3 and counts the number of times the magnetic member 3 changes from forward rotation to reverse rotation or from reverse rotation to forward rotation.
[0058] The sensor 4 detects the rotation angle of the magnetic part. The sensor 4 can be an encoder, a Hall sensor or a reed switch. The rope collection mechanism includes a coil spring 5, which is arranged in the turntable 2, the inner end of the coil spring 5 is connected to the housing 1, and the outer end of the coil spring 5 is connected to the turntable 2. The ruler rope 20 is arranged in the housing 1 and wound outside the turntable 2, the inner end of the ruler rope 20 is connected to the turntable 2, and the outer end of the ruler rope 20 extends out of the rope opening 13.
[0059] In the process of collecting and releasing the rope, the ruler rope 20 can drive the turntable 2 to rotate, and the magnetic part 3 on the turntable 2 will also rotate. The sensor 4 can obtain the parameter information of the length change of the ruler rope 20 according to the magnetic field change generated when the magnetic part 3 rotates. And because the arrangement of the magnetic poles of the magnetic part 3 is that the adjacent magnetic poles along the circumferential direction of the magnetic part 3 are alternately different, the sensor 4 is arranged at one end of the axial direction of the magnetic part 3. Therefore, no matter where the magnetic part 3 rotates with the turntable 2 to stay, the sensor 4 can sense the magnetic field change of the magnetic part 3, thereby obtaining the parameter information of the ruler rope 20 when it stays at any length, and there is no induction dead zone. And in the process of releasing the rope, the coil spring 5 can be deformed with the rotation of the turntable 2 and store elastic potential energy. After the tension of the ruler rope 20 is released, the coil spring 5 can release the elastic potential energy to drive the turntable 2 to rotate to achieve rope collection.
[0060] Figure 4An axial schematic diagram of an arrangement of magnetic poles of a magnetic member 3 is shown, wherein the magnetic member 3 is cylindrical, wherein half of the cylinder is an N pole and the other half of the cylinder is an S pole. In other embodiments, the magnetic member 3 may also be annular, wherein half of the ring is an N pole and the other half of the ring is an S pole. Of course, the number of N poles and S poles may also be two, four or six.
[0061] The turntable 2 includes a rotating shaft 21 and a rotating ring 22 surrounding the rotating shaft 21, and the rotating shaft 21 is rotatably connected to the housing 1. The magnetic member 3 is disposed at one end of the rotating shaft 21. The turntable 2 is rotatably assembled with the housing 1 through the rotating shaft 21, so that the track of the rotating shaft 21 of the turntable 2 is more stable. The rotating shaft 21 serves as the rotating shaft 21 of the turntable 2, and the magnetic member 3 is disposed at one end of the rotating shaft 21 to ensure that the magnetic member 3 and the turntable 2 rotate coaxially.
[0062] One end of the rotating shaft 21 is provided with a mounting groove 211, and the magnetic member 3 is arranged in the mounting groove 211. The mounting groove 211 is used to mount the magnetic member 3, thereby increasing the connection area between the rotating shaft 21 and the magnetic member 3 and preventing the magnetic member 3 from falling off the rotating shaft 21.
[0063] The smart tape measure also includes bearings, including a first bearing 61 and a second bearing 62, which are respectively mounted at both ends of the rotating shaft 21. The cooperation between the rotating shaft 21 and the bearings makes the rotating disk 2 rotate more smoothly, thereby improving the smoothness of the ruler rope 20 during the process of winding and releasing the rope.
[0064] The smart measuring tape also includes a circuit board 7, which is disposed in the housing 1 and fixedly connected to the housing 1. The sensor 4 is integrated on the circuit board 7, which is conducive to product miniaturization. At the same time, the response between the sensor 4 and other electronic components on the circuit board 7 is faster.
[0065] A communication module can also be integrated on the circuit board 7 so that the smart tape measure can establish communication with the software. With the precise data of the tape measure, combined with the software, a better training plan can be provided for the user, just like a personal trainer, making the training more purposeful and effective.
[0066] The smart tape measure also includes a display screen that is signal-connected to the sensor 4 , and the display screen can intuitively display the length of the tape 20 and movement information obtained based on parameter information of the tape 20 .
[0067] The smart tape measure also includes a partition plate 8. The partition plate 8 is fixedly connected to the shell 1 and divides the interior of the shell 1 into a first space and a second space. The partition plate 8 is provided with a mounting sleeve 81 located in the first space. The turntable 2, the magnetic member 3, the coil spring 5 and the ruler rope 20 are all arranged in the first space, and the rotating shaft 21 is arranged in the mounting sleeve 81, and the rotating ring 22 is arranged outside the mounting sleeve 81. The coil spring 5 is arranged between the mounting sleeve 81 and the rotating ring 22, the inner end of the coil spring 5 is connected to the mounting sleeve 81, and the outer end of the coil spring 5 is connected to the rotating ring 22. The circuit board 7 is arranged in the second space. The coil spring 5 is clamped between the partition plate 8 and the shell 1 on both sides of the first space, and the coil spring 5 and the circuit board 7 are separated on both sides by the partition plate 8 to avoid damage to the circuit board 7 during the deformation of the coil spring 5.
[0068] An annular retaining ring 111 is provided in the housing 1, and a notch 1111 is provided on the retaining ring 111. The rotating disk 2, the coil spring 5 and the ruler rope 20 are all arranged in the retaining ring 111. The outer end of the ruler rope 20 extends out of the notch 1111 and the rope outlet 13 in sequence. The retaining ring 111 gathers the ruler rope 20 outside the rotating disk 2 in the retaining ring 111, avoiding the retaining ring 111 from being annular, so that the ruler rope 20 between the retaining ring 111 and the rotating disk 2 will not become too loose and messy during the process of collecting and releasing the rope.
[0069] The housing 1 includes a first housing 11 and a second housing 12 that are detachably connected, which can facilitate the installation of internal parts of the housing 1 and the maintenance of the smart measuring tape.
[0070] The smart tape measure also includes a fixing component 9. When the fixing component 9 is triggered, it can prevent the ruler rope 20 from moving. When the smart tape measure is not installed on the strength training equipment, it can also be used as a ruler for measurement. The structure of the fixing component 9 can refer to the ruler in the relevant technology, and will not be repeated here.
[0071] See also Figure 5 The strength training device provided by an embodiment of the utility model includes a frame 100 and a moving part 200 that can move relative to the frame 100. The fitness equipment training digital acquisition device also includes the smart tape measure in any of the above embodiments, the housing 1 is connected to the frame 100, and the outer end of the tape 20 is connected to the moving part 200.
[0072] When the moving part 200 moves, as the length of the moving rope 20 of the moving part 200 changes, the number of times the rope 20 is pulled in and out is the number cycle of the exercise process. According to the change in the length of the rope 20, exercise information such as the number of training sessions, frequency, stroke, and consumption can be obtained.
[0073] Because the solution of the ruler rope 20 is adopted, it is only necessary to fix the shell 1 on the frame 100 and fix the outer end of the ruler rope 20 on the moving part 200. Therefore, there is no need to modify the strength training equipment. It is only necessary to fix the shell 1 on the frame 100 by means of a strap, tape or screw connection, or first install a bracket on the frame 100, and then install the shell 1 of the smart tape measure on the bracket. There is no need to change the design and production process of the strength training equipment, and the only increased cost is the cost of purchasing the smart tape measure. The shell 1 can also be provided with a data transmission and charging interface. In addition, the smart tape measure can also be provided with equipment such as an instrument panel, and data can be transmitted through the data transmission and charging interface to facilitate the retrieval of data for users to view. In addition, the smart tape measure can also be provided with a communication module, so that users can obtain data through Bluetooth and APP communication, and store the data in the APP to store and analyze the data.
[0074] The moving component 200 includes at least one weight plate, and a plug hole is provided on the weight plate. The outer end of the ruler rope 20 is connected with a pin, and the pin can be inserted into the plug hole.
[0075] When the outer end of the ruler cord 20 is inserted into the sockets on different weight plates, the length of the ruler cord 20 changes, and the current weight information can be known. Specifically, when the pin is inserted into the socket in the first weight plate above, the ruler cord 20 has a first length, and the weight is one weight plate. When the pin is inserted into the socket in the second weight plate above, the ruler cord 20 has a second length, and the weight is two weight plates.
[0076] Strength training equipment can be equipment with weight plates as described above, or it can be fitness equipment such as rowing machines and gantry machines, etc., and the examples are not exhaustive here.
