Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the 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 fixed 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 contraction resistance along with the self stretching and extension in a certain telescopic range; the adjusting fixing section 1b is made of nylon materials in a weaving mode, and has extremely strong wear resistance and stretch-proof deformation resistance, and meanwhile due to the characteristics of materials and manufacturing forming of the adjusting fixing section 1b, a non-smooth surface is formed, so that the adjusting fixing section 1b can be conveniently locked and positioned at each position through the clamping effect of an external device in the using process.

The adjustable tension detection module also comprises a retraction locking mechanism 2 used for fixing the adjustable resistance belt 1 at different positions and a tension transmission feedback mechanism 3 used for detecting the magnitude of tension generated on the adjustable resistance belt 1 in real time. Specifically, the main body component of the retractable locking mechanism 2 is made of aluminum or stainless steel, and can be divided into a connecting support member 2a, a clamping locking member 2b and a torsion spring 6 arranged between the connecting support member and the clamping locking member. The connecting and supporting member 2a is a flat block-shaped cuboid, a containing area for installing the clamping locking piece 2b is formed in the connecting and supporting member, cylindrical grooves or through holes are formed in two sides of the containing area, and correspondingly, cylindrical inserting parts for inserting into the grooves or the through holes are formed in two sides of the clamping locking piece 2 b. When the snap-in lock 2b is fitted to the joint support 2a, the two parts are connected in an articulated manner with a gap 7 formed therebetween for the passage of the aforementioned adjustable resistance band 1, said snap-in lock 2b being able to rotate about a central axis relative to the joint support 2 a. The clearance hole seam 7 comprises a first locking surface 4 and a second locking surface 5, wherein the first locking surface 4 is positioned on the clamping locking piece 2b, the second locking surface 5 is positioned on the connecting support piece 2a, and the first locking surface 4 is a curved surface which gradually increases the distance between the first locking surface 4 and the hinge center along the clockwise or anticlockwise direction around the hinge center; a pressing part 2ba extending towards one side far away from the hinge center of the connecting support part 2a is formed on the clamping locking part 2 b; the outer side of the hinged part is also sleeved with a metal torsion spring 6, 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 prop against each other. When a user applies pressure on the pressing part 2ba to overcome the elastic force of the metal torsion spring 6, the clamping locking piece 2b rotates around the hinge center of the clamping locking piece and the connecting support piece 2a to one direction, at the moment, a gap aperture 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 aperture 7 and freely move back and forth; when adjusting resistance area 1 and removing to required position, the user contacts the pressure of pressing the portion 2ba, and under metal torsion spring 6's effect, block locking piece 2b is around articulated center reverse rotation, and clearance aperture 7 that forms between first locking surface 4 and the second locking surface 5 at this moment diminishes, supports the effect of leaning on realizing the location locking until two locking surfaces are complete with the regulation fixed segment 1b both sides face centre gripping on adjusting resistance area 1. When the position of the adjustment resistance belt 1 needs to be changed or the adjustment resistance belt is stored, the locked state can be released only by pressing the rotation engagement locking piece 2b again.

Further, all be formed with the anti-skidding structure that is used for promoting frictional force in order to promote locking stability on first locking face 4 and second locking face 5, specifically, be formed with outside bellied latch 4a on first locking face 4, be formed with inside sunken draw-in groove 5a on second locking face 5.

The tension transmission feedback mechanism 3 in the adjustable tension detection module is positioned below the retraction locking mechanism 2 and comprises an upper connecting arm 3a, a lower connecting arm 3b and a measuring component 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 vertically-penetrating bolt and nut structure, so that the whole tension transmission feedback mechanism 3 is Z-shaped. The measuring component 3c is specifically a metal piece provided with a sensor, when two end parts of the measuring component 3c are respectively under the influence of vertical acting forces in opposite directions of the upper connecting arm 3a and the lower connecting arm 3b, the deformation quantity generated by the metal piece can change the resistance value of the metal piece, and the sensor correspondingly calculates the tensile force borne between the upper connecting arm and the lower connecting arm 3b in the vertical direction by detecting the change of the resistance value, namely the magnitude of the real-time acting force applied to the adjustable tensile force detection module by the user through adjusting the resistance belt 1.

A through hole is arranged above the upper connecting arm 3a, a corresponding through hole is also arranged below the connecting and supporting piece 2a, and a bolt simultaneously passes through the through holes of the two parts and is locked and fixed in the axial direction by a nut. At the moment, the retraction locking mechanism 2 is hinged with the tension transmission feedback mechanism 3, so that the retraction locking mechanism 2 can rotate around a hinge center relative to the tension transmission feedback mechanism 3. This hinge structure can make receive and release locking mechanism 2 and keep flat after rotating, has solved and has installed the problem that the structure occupation space of outside bellied is great and be not convenient for accomodate and place when actual product is last.

In the use process, a user firstly releases the locking state of the folding and unfolding locking mechanism 2 by pressing the folding and unfolding locking mechanism, the adjusting resistance belt 1 is pulled out to a certain position and is not folded and unfolded with the locking mechanism 2, and the position of the adjusting resistance belt 1 is fixed under the clamping and abutting action of the folding and unfolding locking mechanism 2. The front end part of the adjusting resistance belt 1 is fixedly connected with the holding device or directly wound and bound on the wrist and the arm of a user, and the adjusting resistance belt 1 is stretched and extended and provides resistance in the opposite direction while 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 form and the action pattern of the user, and the length of the adjusting resistance belt 1 and the corresponding elastic resistance are adjusted by changing the clamping position of the adjusting fixing section 1b by the folding and unfolding locking mechanism 2.

After the user finishes a stretching and relaxing process on the adjusting resistance belt 1, the tension transmission feedback mechanism 3 acquires tension change conditions in the process, correspondingly obtains a series of data such as the magnitude of a tension peak value and energy consumed by work doing through internal program analysis and calculation, and sends the data to a mobile phone or other intelligent equipment of the user, so that the user can accurately master the exercise condition of the user.

In twice looks spaced use, because the centre need accomodate regulation resistance area 1, lead to same user to need to debug the location repeatedly to regulation resistance area 1 clamping position again when taking exercise the second time, increased the loaded down with trivial details degree of use. Therefore, the adjustment resistance band 1 is further optimized, and a plurality of numerical scale positions 8 are marked on the adjustment fixing section 1b of the resistance band at certain same intervals, so that a user can rapidly position to the last clamping position when the device is re-unfolded every time so as to rapidly position or adjust the clamping position according to new exercise content.

In the use that lasts, because adjust resistance area 1 and inevitably appear certain deformation inefficacy in the in-process of stretching the shrink repeatedly, compare under initial condition, will adjust resistance area 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. In the practical application process of the product, the resistance belt 1 which is not stretched is stretched to a certain length and the tensile force value is recorded; after the adjustable resistance band 1 is used for a certain time by a user, the adjustable resistance band 1 is stretched to the same length again, the tension value is recorded, the measurement and comparison are carried out through the internal program of the detection module, the reliability of the adjustable resistance band 1 is analyzed, and the safety of the user to the human body in the use and exercise process is ensured.

Example 2: because receive and release locking mechanical system 2 and can rotate for between the pulling force transmission feedback mechanism 3, can't ensure that the user passes through the adjusting resistance area 1 and follows vertical direction completely to the effort that pulling force transmission feedback mechanism 3 exerted, can lead to measuring the pulling force numerical value size that obtains and the user actually exert the condition emergence of the effort size on adjusting resistance area 1 not corresponding this moment, influence the accuracy nature of testing result greatly. Therefore, the adjustable tension detection module is further preferable on the basis of embodiment 1.

Because the adjusting resistance belt 1 is clamped, locked and fixed by the retracting and releasing locking mechanism 2, and the locking position is far away from the hinged position of the retracting and releasing locking mechanism 2 and the tension transmission feedback mechanism 3, the adjusting resistance belt 1 can be regarded as an integral structure with the retracting and releasing locking mechanism 2 in the use process, namely the stretching and extending direction of the adjusting resistance belt 1 is parallel to the deflection direction of the retracting and releasing locking mechanism 2. Therefore, an angle sensor for measuring the deflection degree between the two parts can be additionally arranged at the hinged part of the retraction locking mechanism 2 and the tension transmission feedback mechanism 3, and the acting force on the adjusting resistance belt 1 can be accurately obtained by combining, analyzing and calculating the angle value obtained by measurement and the vertical tension value obtained by the measuring component 3 c.

Example 3: an adjustable tension detection device comprises the adjustable tension detection module of embodiment 1 or 2, and further comprises a resistance belt storage module 9. The resistance band 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 adjusting resistance band 1. When the adjusting resistance belt 1 is pulled out and fixed outwards, the coil spring 9a is elastically deformed; when a 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, and under the action of the elastic force of the coil spring 9a, the adjusting resistance belt 1 is pulled back to be accommodated in the resistance belt accommodating module 9, so that the occupied space of the device in the accommodating 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, a sensor capable of detecting the acting force in the horizontal direction can be additionally arranged, and the acting force on the adjusting resistance belt 1 can be analyzed, calculated and accurately obtained by combining the tension value in the vertical direction obtained through analysis.

Example 4: the utility model provides an intelligence body-building activity equipment 10, includes main part 10a and embodiment 3 that are flat cuboid shape adjustable tension detection device, adjustable tension detection device symmetry sets up in the both sides of main part 10 a. Place main part 10a on ground when using, through the regulation resistance area 1 with both sides simultaneously outwards stretching to certain length locking fixed and be connected simultaneously through the both ends of metal spring buckle with a member, the user both feet divide to stand in the both sides at main part center in line, and both hands grip the member simultaneously and overcome elastic resistance and upwards carry out the lifting, realize the body-building exercise action of simulating heavy burden hard-drawn at this in-process. Furthermore, the user can also carry the rod on the shoulder to simulate the exercise of deep squat with load or lift the rod up by lying on the main body 10a to simulate the exercise of lying and pushing. According to the actual use requirement, the intelligent fitness activity equipment 10 can also simulate various series of actions such as dumbbell inclined pushing, bird flying and the like, has wide and rich application modes, has extremely high safety in the use process, and can effectively avoid the condition that the human body is injured due to improper use of equipment.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention.
