Abstract
An acting force measuring device for exercise equipment comprises three rotating components, at least one force sensor and at least one bracket, wherein the three rotating components are horizontally arranged at certain intervals along the moving direction of a belt or a steel cable of the exercise equipment, the rotating component in the middle and the two rotating components on the two sides are all in contact with the belt or the steel cable on the two sides thereof, the relative positions of the three rotating components are fixed, and the force sensor is in contact with the rotating component in the middle. The utility model has the advantages that the installation of the device demands position instead of height; and an on-site calibration is no more needed as long as the device is calibrated in production.
Description
Technical field:
The utility model belongs to a kind of body-building apparatus, particularly a kind of with the pouring weight be the load fitness equipment on use the force measurement device.
Background technology:
With the pouring weight is load, and the fitness equipment that draws pouring weight with belt or cable wire is traditional mechanical body-building apparatus.Recently, people install some sensors and measure, write down, calculate the data relevant with person taking exercise's motion with demonstration with electronic installation on this class fitness equipment, and as parameters such as times of exercise, acting force, motion works done, wherein acting force is an important indicator.Have many kinds of methods can be used for measuring this acting force at present, one of method is exactly to calculate this acting force by the tension force of measuring belt or cable wire, because the tension force of belt or cable wire and the relation between the acting force are proportional.
Now, the measuring method of this tension force realizes by add a force measurement device on fitness equipment.In most cases, this force measurement device is installed between original two reverse wheels of fitness equipment, have only a runner assembly in this force measurement device generally speaking, this runner assembly contacts with belt or cable wire, and has changed belt or the original motion track of cable wire.As everyone knows, for the load of same weight, the variation of belt or cable wire motion track is big more, and the tension force that produces at the force measurement device is just big more, if the too little meeting of the tension force that produces influence the sensitivity of measurement mechanism, may exceed the range of measurement mechanism if the tension force that produces is too big.Therefore, this force measurement device all has certain requirement to the position and the setting height(from bottom) of installing, and after installation, also needs to carry out field calibration work, and this has just brought many inconvenience to the user; The first, calibration operation is a technical work, done by the personnel of training; The second, there is not suitable position that this device is installed on some fitness equipment.
Summary of the invention:
The purpose of this utility model is to solve the weak point of existing product, provides a kind of field calibration that do not need, the force measurement device that uses on the fitness equipment of being more convenient for installing.
The technical scheme that the utility model adopted is: the force measurement device that uses on a kind of fitness equipment is characterized in that: be made up of three runner assemblies, at least one force transducer and at least one support; Three runner assemblies are in one line at a certain distance along the direction of motion of the belt of fitness equipment or cable wire, and the runner assembly in the middle of wherein being positioned at contacts with belt or cable wire at belt or cable wire both sides respectively with two runner assemblies that are positioned at both sides; The relative position of three runner assemblies is changeless; Force transducer contacts with the runner assembly of centre.
Above-mentioned force transducer can be silicon piezoresistance type, strain-type, piezoelectric type with capacitive.
Above-mentioned runner assembly can be made up of bearing and stationary shaft.
Above-mentioned runner assembly can be made up of rotation axis and stationary shaft.
Above-mentioned runner assembly can be made up of rotation axis, bearing and stationary shaft.
The utility model has the advantages that: 1, because three runner assemblies are in one line at a certain distance along the direction of motion of the belt of fitness equipment or cable wire, runner assembly in the middle of wherein being positioned at contacts with belt or cable wire at belt or cable wire both sides respectively with two runner assemblies that are positioned at both sides. so this device only is equipped with requirement to the installation position, and setting height(from bottom) is not required .2, no matter how external condition changes, signal that force transducer produced of this device and the scale-up factor between the acting force are changeless. like this, after this device is calibrated in process of production, carried out field calibration with regard to not needing.
Description of drawings:
Fig. 1 is a scheme of installation of the present utility model.
Fig. 2 is a front view of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Embodiment:
As shown in Figure 1: between two original reverse wheels 13 and 14 of fitness equipment 11, force measuring device 12 has been installed, can have been accessed suitable tension force, added two cushion blocks 5 and 6 in order to make force measuring device 12; Installed after the force measuring device 12, variation has taken place in belt or cable wire motion track, and the original motion track of belt or cable wire is 17; Pouring weight is 18.
Shown in Fig. 2,3: three runner assemblies 1,2,3 is in one line at a certain distance along the direction of motion of belt, runner assembly 1 in the middle of wherein being positioned at contacts with belt in the belt both sides respectively with 3 with two runner assemblies 2 that are positioned at both sides, and the movement locus of belt is changed through these three runner assemblies the time.4 of force transducers contact with runner assembly 1 in the middle of being positioned at.Above-mentioned runner assembly can be made up of bearing and stationary shaft, also can be made up of rotation axis and stationary shaft, can also be by being made up of rotation axis, bearing and stationary shaft.Above-mentioned force transducer can be silicon piezoresistance type, strain-type, piezoelectric type with capacitive.
Relative position owing to three runner assemblies in this device is changeless, therefore the variable quantity of belt or cable wire motion track is fixed in this device, such structure just makes the tension force that produced on the runner assembly of centre and the scale-up factor between the acting force immobilize, and, force transducer contacts with the runner assembly that is positioned at the centre, force transducer can directly be experienced the size of tension force, that is to say, no matter how external condition changes, signal and the scale-up factor between the acting force that this device inner force sense device is produced are changeless.Like this, after this device is calibrated in process of production, carried out field calibration, and this device only is equipped with requirement to the installation position, and setting height(from bottom) is not required with regard to not needing.
