Description

Strength training device with weight measurement and speed measurement function

technical field

The utility model belongs to the field of fitness equipment, in particular to a strength training device with functions of measuring weight and speed.

Background technique

The current strength training devices generally use pull ropes to bypass the pulley blocks to connect counterweights for strength training. Counterweights, number of sets, and speed are the key parameters of strength training. Traditional strength training devices cannot collect these parameters, resulting in ineffective strength training. Well, in order to solve this problem, those skilled in the art have added various parameter acquisition devices on the strength training device, but most of the current parameter acquisition devices have the defects of complex structure, high cost, and inaccurate data collection. For example, some strength trainers install weighing sensors to collect counterweight parameters.

This solution only uses one high-frequency laser rangefinder, which can simultaneously collect the speed information of the counterweight, group number, and pull rope, without using contact measurement, and the position of the high-frequency laser rangefinder can be flexibly installed, without Affected by the impact of the weight plate, the measurement result is accurate.

As a solution of the utility model: the laser rangefinder is a low-frequency laser rangefinder.

The low-frequency laser rangefinder of the present utility model is a commercially available product in the prior art, which can measure the distance between the counterweight plate pin (static), calculate the group number of the counterweight plate, and then obtain the weight of the counterweight plate. data.

When a low-frequency laser rangefinder is used, in order to enable the utility model to measure the speed of the pull rope, a speed measuring wheel is provided on one side of the gantry of the utility model, and the pull rope bypasses the speed measuring wheel in turn. There is a photoelectric code disc, and a photoelectric sensor matching the photoelectric code disc is arranged on the gantry or the speed measuring wheel bracket.

In the utility model, the speed measuring wheel is arranged on the inner wall of one side of the gantry frame, the pressure and impact of the pull rope on the speed measuring wheel are small, the speed measuring wheel is not easily damaged, and the speed measuring result is accurate.

The laser range finder, photoelectric code disc and photoelectric sensor of the present utility model are all commercially available products with mature prior art, which can be connected with single-chip microcomputer or processor signal of prior art strength trainer, and the data collected will be displayed on on the display.

The measuring method of the strength training device with weighing and speed measuring functions of the utility model is characterized in that a laser range finder is arranged above or below the counterweight plate, so that the laser emitting end is facing the handle or front end of the counterweight plate pin, and the laser The rangefinder detects the height information of the weight plate pin, and converts it into the number of groups and weight data of the weight plate.

When the laser rangefinder of the utility model sends out high-frequency laser pulses, it can detect the height change of the weight plate when it is dynamic, and use the detected height change to calculate the moving speed of the weight plate, that is, the speed of the pull rope .

When the laser rangefinder of the present invention sends out low-frequency laser pulses, in order to be able to detect the speed of the rope, the speed of the rope is detected by a photoelectric code disc.

The utility model has the advantages of reasonable structure, convenient use, accurate measurement results and long service life.
