[0055] 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.
[0056] 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.
[0057] 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.
[0058] See also Figures 1 to 5 The first embodiment of the utility model provides a smart tape measure comprising a housing 1, a turntable 2 and a round rope (not shown). The housing 1 is provided with a rope outlet 11. The turntable 2 is rotatably arranged in the housing 1, and a guide structure is provided on the outer wall of the turntable 2 in the circumferential direction. The inner end of the round rope is connected to the turntable 2, and the outer end of the round rope extends out of the rope outlet 11, and the round rope can be wound around the outer wall of the turntable 2 in the circumferential direction under the rotation of the turntable 2.
[0059] The guiding structure is used to guide the winding position of the round rope.
[0060] Through the above-mentioned structural design, when the round rope is wound around the outer wall of the turntable 2 in the circumferential direction under the rotation of the turntable 2, the guiding structure can guide the winding position of the round rope, so that the round rope can be wound around the turntable 2 more regularly and evenly, thereby avoiding the problem that the round rope collapses when it is wound and superimposed to a certain height at a certain position due to a large height difference with other positions, resulting in invalid idling of the turntable 2 and inaccurate measurement of the length of the round rope, thereby improving the accuracy of the smart tape measure in measuring the length of the round rope.
[0061] The guide structure includes a rope winding groove 21, which includes a thread groove 211 and a rope return groove 212. The thread groove 211 is in a thread shape, and the rope return groove 212 connects the end of the thread groove 211 and the beginning of the thread groove 211. The round rope can be wound in the thread groove 211 and the rope return groove 212 under the rotation of the turntable 2.
[0062] The round rope is wound around the turntable 2 from the head end of the thread groove 211 along the track of the thread groove 211. When the round rope is wound to the end of the thread groove 211, it can return to the head end of the thread groove 211 along the track of the rope return groove 212, and thus winds around the turntable 2 reciprocatingly along the thread groove 211 and the rope return groove 212. The thread groove 211 and the rope return groove 212 play the role of organizing and storing the round rope, so that the round rope can be wound around the turntable 2 more regularly and evenly.
[0063] The turntable 2 includes a rotating ring 22, and the rotating ring 22 includes a ring body 221 and a clamping ring. The rope winding groove 21 is provided on the outer side wall of the ring body 221 in the circumferential direction. The clamping ring is connected to the outer side wall of the ring body 221 in the circumferential direction. The clamping ring includes a first clamping ring 222 and a second clamping ring 223, and the first clamping ring 222 and the second clamping ring 223 are respectively located on both sides of the rope winding groove 21 in the axial direction of the ring body 221.
[0064] The area between the first clamp ring 222 and the second clamp ring 223 can be used to wind the round rope. When the height of the round rope wound in the rope winding groove 21 exceeds the depth of the rope winding groove 21, the extra round rope will be stored between the first clamp ring 222 and the second clamp ring 223 to avoid the round rope being messy. It is worth mentioning that since the rope winding groove 21 plays a role in organizing the round rope, the round rope wound in the rope winding groove 21 also has a spiral trajectory. When the height of the round rope exceeds the depth of the rope winding groove 21, although the rope winding groove 21 loses its function of organizing the rope, the wound round rope in the shape of a spiral will play a role in organizing the round rope wound later, so that the round rope can still be wound neatly and evenly on the turntable 2.
[0065] In this embodiment, the rotating ring 22 further includes a threaded ring 224. The threaded ring 224 is connected to the outer side wall of the ring body 221 in the circumferential direction, and the threaded ring 224 is in the shape of a thread line. The intervals between the threaded rings 224 form a rope winding groove 21. The threaded ring 224 is provided with a plurality of notches, and the connecting line of the plurality of notches forms a rope return groove 212. The first clamping ring 222 and the second clamping ring 223 are respectively located on both sides of the threaded ring 224 in the axial direction of the ring body 221.
[0066] The diameter of the clamp ring is larger than the diameter of the threaded ring 224. When the height of the round rope wound in the rope groove 21 exceeds the threaded ring 224, the excess round rope will be stored between the first clamp ring 222 and the second clamp ring 223 to avoid the round rope being messy.
[0067] The rotating ring 22 also includes a rotating shaft 23, and the rotating shaft 23 is rotatably connected to the housing 1. The rotating ring 22 surrounds the rotating shaft 23. By assembling the rotating shaft 23 and the housing 1, the rotation track of the rotating disk 2 is more stable, and the accuracy of measuring the length of the round rope can be improved to a certain extent.
[0068] The groove width of the thread groove 211 is greater than one time the rope width of the round rope and less than two times the rope width of the round rope. The groove width of the rope return groove 212 is greater than one time the rope width of the round rope and less than two times the rope width of the rope return groove 212. With such a design, the round rope can smoothly enter the thread groove 211 and the rope return groove 212, and will not be loosely entangled in the thread groove 211 and the rope return groove 212, thereby avoiding the situation in which the thread groove 211 and the rope return groove 212 collapse due to excessive stacking height.
[0069] The smart measuring tape also includes a rope collecting mechanism 3 and a data acquisition module 4. The rope collecting mechanism 3 is disposed in the turntable 2, and the rope collecting mechanism 3 drives the turntable 2 to rotate in a positive direction. The round rope can be collected under the driving force provided by the rope collecting mechanism 3. The data acquisition module 4 is used to detect the angle change of the turntable 2.
[0070] When the ruler rope is subjected to external force and overcomes the driving force of the rope collection mechanism 3 to release the rope, the ruler rope can drive the turntable 2 to rotate in the opposite direction. When the ruler rope is subjected to the driving force of the rope collection mechanism 3 to collect the rope, the rope collection mechanism 3 can drive the turntable 2 to rotate in the forward direction. That is to say, the angle of the turntable 2 changes during the process of collecting and releasing the rope. By detecting the angle change of the turntable 2 through the data acquisition module 4, the length change of the ruler rope can be obtained.
[0071] The data acquisition module 4 is also used to count the number of times the turntable 2 changes from forward rotation to reverse rotation or from reverse rotation to forward rotation.
[0072] The smart tape measure can be used on strength training equipment. The housing 1 is connected to the frame of the strength training equipment. The outer end of the tape measure is connected to a moving part that can move relative to the frame. The weight information of the moving part can be obtained by detecting the angle change of the turntable 2 and obtaining the length change of the tape measure through the data acquisition module 4. Specifically, the moving part includes at least one weight plate, and the weight plate is provided with a socket. The outer end of the round rope is connected to a pin, and the pin can be inserted into the socket. When the outer end of the round rope is inserted into the socket on different weight plates, the length of the round rope changes, and the current weight information can be known.
[0073] The number of times the turntable 2 changes from forward rotation to reverse rotation or from reverse rotation to forward rotation is counted by the data acquisition module 4 to obtain the number of times the ruler rope changes from contraction to release or from release to retraction, and the number of times the moving parts move. There is no need to modify the strength training equipment, which reduces the cost of use, and can accurately measure the sports training data of interest.
[0074] The data acquisition module 4 includes a magnetic member 41 and a sensor 42. The magnetic member 41 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 41 are alternately different. The sensor 42 is arranged in the housing 1 and at one end of the axial direction of the magnetic member 41. The sensor 42 detects the angle change of the magnetic member 41. The sensor 42 can be an encoder, a Hall sensor 42 or a reed switch. The rope collection mechanism 3 includes a coil spring, the inner end of which is connected to the housing 1, and the outer end of which is connected to the turntable 2.
[0075] During the process of collecting and releasing the round rope, the turntable 2 can be driven to rotate, and the magnetic part 41 on the turntable 2 will also rotate. The sensor 42 can obtain parameter information of the length change of the round rope according to the magnetic field change generated when the magnetic part 41 rotates. And because the arrangement of the magnetic poles of the magnetic part 41 is that the adjacent magnetic poles along the circumferential direction of the magnetic part 41 are alternately different, the sensor 42 is arranged at one end of the axial direction of the magnetic part 41. Therefore, no matter where the magnetic part 41 rotates with the turntable 2 to stay, the sensor 42 can sense the magnetic field change of the magnetic part 41, thereby obtaining parameter information when the round rope stays at any length, and there is no induction dead zone. And in the process of releasing the rope, the coil spring can be deformed with the rotation of the turntable 2 and store elastic potential energy. After the tension of the round rope is released, the coil spring can release the elastic potential energy to drive the turntable 2 to rotate to achieve rope collection.
[0076] See also Figures 6 to 9 The main difference between the smart measuring tape provided by the second embodiment of the utility model and the first embodiment is the difference in the guiding structure, and the ceramic ring 6 for the round rope to pass through is provided at the rope outlet 11 of the second embodiment.
[0077] The guide structure on the turntable 5 of the smart tape measure of the second embodiment includes an inclined wedge. The two axial ends of the turntable 5 are respectively a first end and a second end. A plurality of inclined wedges are provided around the turntable 5 at circumferential intervals. The inclined wedges include a first inclined wedge 51 and a second inclined wedge 52. The first inclined wedge 51 is provided at the first end of the turntable 5, and the inclined surface of the first inclined wedge 51 faces the second end of the turntable 5. The second inclined wedge 52 is provided at the second end of the turntable 5, and the inclined surface of the second inclined wedge 52 faces the first end of the turntable 5.
[0078] The round rope can be firstly wound around the middle position of the turntable 5 in the axial direction under the guidance of the inclined surfaces of the first inclined wedge 51 and the second inclined wedge 52, and then spread to both sides of the axial direction of the turntable 5 when the round rope is stacked to a certain height. However, in this process, the inclined surfaces of the first inclined wedge 51 and the second inclined wedge 52 always have a force to converge the round rope inward, which plays the role of wire organization and storage, so that the round rope can be wound around the turntable 5 more regularly and evenly.
[0079] In this embodiment, there is one first oblique wedge 51 , and two second oblique wedges 52 , and the three oblique wedges are arranged at an angle of 60 degrees.
[0080] The function of the ceramic ring 6 is to reduce the friction force on the round rope, prevent the round rope from being worn, and increase the service life of the round rope.
