Detailed Description
The following specific examples are intended to be illustrative of the invention and are not intended to be limiting, as modifications of the invention will be apparent to those skilled in the art upon reading the specification without inventive contribution thereto, and are intended to be protected by the patent law within the scope of the appended claims.
The scheme is realized by the following technical means:
Example 1: an adjustable tension detection module comprises an adjustable resistance belt 1; the adjusting resistance belt 1 can be divided into an elastic telescopic section 1a and an adjusting fixing section 1b which are fixedly connected with each other; the elastic telescopic section 1a is made of elastic materials such as rubber or latex materials, and can provide gradually-changed shrinkage resistance along with the stretching extension of the elastic telescopic section in a certain telescopic range; the adjusting and fixing section 1b is woven by nylon materials, has extremely strong wear resistance and tensile deformation resistance, and meanwhile, the adjusting and fixing section 1b forms a non-smooth surface due to the characteristics of materials and manufacturing and forming, so that the adjusting and fixing section 1b can be conveniently locked and positioned at all positions through the clamping action of an external device in the use process.
The adjustable tension detection module further comprises a winding and unwinding locking mechanism 2 for fixing the adjustable resistance belt 1 at different positions and a tension transmission feedback mechanism 3 for detecting the magnitude of the tension value generated on the adjustable resistance belt 1 in real time. Specifically, the main body of the housing locking mechanism 2 is made of aluminum or stainless steel, and may be divided into a connection support 2a, an engagement locking member 2b, and a torsion spring 6 installed therebetween. The connecting support 2a is a flat block cuboid, a containing area for installing the clamping locking piece 2b is formed in the connecting support, cylindrical grooves or through holes are formed in two sides of the containing area, and cylindrical inserting portions for being inserted into the grooves or the through holes are formed in two sides of the clamping locking piece 2b correspondingly. When the snap-in locking element 2b is mounted in engagement with the connecting support element 2a, the two parts are connected in an articulated manner with a clearance slit 7 formed between them for the passage of the aforementioned adjusting resistance belt 1, said snap-in locking element 2b being rotatable about a central axis relative to the connecting support element 2 a. The gap hole seam 7 comprises a first locking surface 4 positioned on the clamping locking piece 2b and a second locking surface 5 positioned on the connecting support piece 2a, wherein the first locking surface 4 is a curved surface with gradually increased distance from the hinging center in the clockwise or anticlockwise direction around the hinging center; the engaging locking member 2b is formed with a pressing portion 2ba extending away from the hinge center side thereof with the connection support member 2 a; a metal torsion spring 6 is sleeved and mounted on the outer side of the hinge joint, and two ends of the torsion spring 6 extend outwards and are respectively clamped with two opposite inner side surfaces of the locking piece 2b and the connecting support piece 2a to abut against each other. When a user applies pressure to the pressing part 2ba to overcome the elastic force of the metal torsion spring 6, the clamping locking piece 2b rotates around the hinging center of the clamping locking piece and the connecting support piece 2a in one direction, at the moment, a gap hole gap 7 formed between the first locking surface 4 and the second locking surface 5 is enlarged, and the adjusting resistance belt 1 can pass through the gap hole gap 7 and can freely move back and forth; when the adjusting resistance belt 1 moves to a required position, a user contacts the pressure on the pressing part 2ba, the clamping locking piece 2b reversely rotates around the hinge center under the action of the metal torsion spring 6, and at the moment, a gap hole gap 7 formed between the first locking surface 4 and the second locking surface 5 is reduced until the two locking surfaces are completely clamped and abutted with the two side surfaces of the adjusting fixing section 1b on the adjusting resistance belt 1, so that the positioning locking effect is realized. When the position of the adjustment resistance belt 1 is changed or the adjustment resistance belt is stored, the locked state can be released only by pressing the rotation engagement locking member 2b again.
Further, an anti-slip structure for improving friction force to improve locking stability is formed on the first locking surface 4 and the second locking surface 5, specifically, a latch 4a protruding outwards is formed on the first locking surface 4, and a slot 5a recessed inwards is formed on the second locking surface 5.
The tension transmission feedback mechanism 3 in the adjustable tension detection module is located below the retractable locking mechanism 2 and comprises an upper connecting arm 3a, a lower connecting arm 3b and a measuring member 3 c. The measuring component 3c is horizontally arranged, and two ends of the measuring component are respectively and fixedly connected with the lower end part of the upper connecting arm 3a and the upper end part of the lower connecting arm 3b into a whole through a bolt and nut structure penetrating up and down, so that the whole tension transmission feedback mechanism 3 is Z-shaped. The measuring member 3c is specifically a metal piece provided with a sensor, when two ends of the measuring member 3c are respectively affected by vertical acting forces in opposite directions of the upper connecting arm 3a and the lower connecting arm 3b, the resistance value of the metal piece can be changed by deformation generated by the metal piece, and the sensor correspondingly calculates the magnitude of the tensile force born by the upper connecting arm 3b and the lower connecting arm 3b in the vertical direction by detecting the change of the resistance value, namely the magnitude of real-time acting force applied to the adjustable tensile force detection module by a user through adjusting the resistance belt 1.
A through hole is formed above the upper connecting arm 3a, a corresponding through hole is formed below the connecting support 2a, and a bolt is inserted through the through holes of both parts at the same time and locked and fixed in the axial direction by a nut. At the moment, the folding and unfolding locking mechanism 2 and the tension transmission feedback mechanism 3 are hinged, so that the folding and unfolding locking mechanism 2 can rotate around the hinge center relative to the tension transmission feedback mechanism 3. This hinge structure can make receive and release locking mechanism 2 keep flat after rotating, has solved the problem that outwards bellied structure occupation space is great and be inconvenient for accomodating and place when installing on actual product.
In the use, the user releases its locking state through pressing receive and release locking mechanism 2 earlier, will adjust resistance area 1 outwards to pull out to a certain position and no longer receive and release locking mechanism 2, and the resistance area 1 is adjusted this moment and is held down the position and fixed under the centre gripping of receive and release locking mechanism 2 and support the effect. The front end of the adjusting resistance belt 1 is fixedly connected with the holding device or directly wound and bound on the wrist and arm of the user, and the adjusting resistance belt 1 is stretched and lengthened and provides opposite resistance when the user stretches upwards. The user can determine the required stretching resistance and the height of the position reached by stretching according to the body shape and the action pattern of the user, and the length and the corresponding elastic resistance of the adjusting resistance belt 1 can be adjusted by changing the clamping position of the adjusting fixing section 1b of the retractable locking mechanism 2.
When the user completes one stretching and releasing process of the adjusting resistance belt 1, the tension transmission feedback mechanism 3 acquires the tension change condition in the process, correspondingly obtains a series of data such as the tension peak value in the process and the energy consumed by acting through internal program analysis and calculation, and sends the data to the mobile phone or other intelligent equipment of the user, so that the user can accurately grasp the exercise condition of the user.
In the use of twice looks interval, because the centre needs accomodate adjusting resistance area 1, lead to same user to need again to adjust resistance area 1 clamping position and debug the location repeatedly when taking exercise for the second time, increased the loaded down with trivial details degree of use. Therefore, the adjusting resistance belt 1 is further optimized, and a plurality of numerical scale positions 8 are marked on the adjusting fixing section 1b of the resistance belt at intervals of a certain same distance, so that a user can quickly position the last clamping position when the device is redeployed each time, and can quickly position or adjust the clamping position according to new exercise content.
In the continuous use, because the adjustment resistance belt 1 inevitably appears certain deformation inefficacy in the in-process of repeated stretching shrinkage, compare in the initial state, will adjust resistance belt 1 and stretch to the same length position just can no longer provide sufficient resistance size for the user, can't ensure stable exercise effect, can have the potential safety hazard of fracture damage simultaneously. When the product is actually applied, the resistance belt 1 which is not subjected to stretching adjustment is stretched to a certain length, and the tensile force value is recorded; after a certain period of use by a user, the adjustable resistance belt 1 is stretched to the same length again and the tensile force value is recorded, the measurement, calculation and comparison are carried out through the internal program of the detection module, the reliability of the adjustable resistance belt 1 is analyzed, and the safety of a human body in the process of use and exercise is ensured.
Example 2: because the retractable locking mechanism 2 can rotate relative to the tension transmission feedback mechanism 3, the situation that the magnitude of the tension value obtained by measurement does not correspond to the magnitude of the acting force actually applied to the adjustable resistance belt 1 by a user can not be ensured to be in the vertical direction completely by the user through the adjustable resistance belt 1 to the acting force applied to the tension transmission feedback mechanism 3 in the use process, and the accuracy of the detection result is greatly influenced. Therefore, on the basis of embodiment 1, the adjustable tension detecting module is further preferable.
Because the adjusting resistance belt 1 is clamped and locked by the winding and unwinding locking mechanism 2 and the locking position is far away from the hinge joint of the winding and unwinding locking mechanism 2 and the tension transmission feedback mechanism 3, the adjusting resistance belt 1 can be regarded as an integrated structure with the winding and unwinding locking mechanism 2 in the use process, namely, the stretching extension direction of the adjusting resistance belt 1 is considered to be parallel to the deflection direction of the winding and unwinding locking mechanism 2. Therefore, an angle sensor for measuring the deflection degree between the two parts can be additionally arranged at the hinge joint of the folding and unfolding locking mechanism 2 and the tension transmission feedback mechanism 3, and the acting force on the adjusting resistance belt 1 can be accurately known by combining the angle value obtained by analysis and calculation and the vertical tension value obtained by the measuring component 3 c.
Example 3: an adjustable tension detecting device comprises the adjustable tension detecting module described in the embodiment 1 or 2, and further comprises a resistance belt accommodating module 9. The resistance belt accommodating module 9 comprises a disc-shaped coil spring 9a and a fixed shell arranged on the outer side of the coil spring 9a, the center of the coil spring 9a is fixedly connected with the shell, and the outer end part of the coil spring 9a is connected with the tail end of the resistance belt 1. When the adjustment resistance belt 1 is pulled out to be fixed, the coil spring 9a is elastically deformed; when the user presses the clamping locking piece 2b of the folding and unfolding locking mechanism 2, the locking state of the adjusting resistance belt 1 is released, the adjusting resistance belt 1 is pulled back to be contained in the resistance belt containing module 9 under the action of the elastic force of the coil spring 9a, the occupied space of the device in the containing state is reduced, meanwhile, the adjusting resistance belt 1 is effectively protected, and the compactness of the structure and the durability of parts are further improved.
Besides the method, the force on the adjusting resistance belt 1 can be calculated and accurately obtained by adding a sensor capable of detecting the force in the horizontal direction and combining the vertical direction pulling force value obtained by analysis.
Example 4: an intelligent fitness equipment 10 comprises a main body member 10a in a flat cuboid shape and the adjustable tension detection devices in embodiment 3, wherein the adjustable tension detection devices are symmetrically arranged at two sides of the main body member 10 a.
