Description

Technical Field

[0001] The utility model relates to the technical field of force detection, in particular to a force detection system. Background Art

[0002] Muscle strength is the basis for the human body to achieve various movements in daily life and participate in various sports. Understanding the maximum force that different muscles and different movements can exert is not only helpful for evaluating a person's physical fitness and health level, but also an important basis for formulating strength training loads.

[0003] The maximum strength test is generally divided into single joint test and compound joint (multi-joint) test. Strength tests for single joint movements such as knee flexion / extension, arm flexion / extension, etc. are generally called single joint strength tests. Through the single joint maximum strength test, we can understand the maximum strength and balance of the agonist and antagonist muscles that control a certain joint, as well as the symmetry of the left and right limbs. Strength tests that require multiple joints to complete movements such as squats, deadlifts, and bench presses are generally called compound joint strength tests. In sports and physical labor, compound joint movements are mostly used. Through the maximum strength test of compound joint movements, we can understand the maximum strength of multiple joints when they move in coordination. In addition, in sports, achieving greater strength in a shorter time is particularly important for competitive events that require explosive power. Therefore, for those engaged in these sports that require explosive power, the fastest time to reach maximum strength should also be tested.

[0004] The existing strength testing methods mainly include the following testing methods.

[0005] (1) Direct testing method using a barbell or dumbbell. This method requires repeated bench pulls and bench presses with a barbell or dumbbell, and the weight of the barbell or dumbbell is continuously increased during the bench pulls and bench presses, which puts a large load on the test subject's body. The test results will also have large errors. In addition, during the bench pulls and bench presses, the barbell or dumbbell will fall off as the test subject becomes tired, which poses a great safety hazard to the test subject during the test and prevents the test subject from achieving the fastest speed to reach maximum strength.

[0006] (2) Indirect testing method using barbells or dumbbells. Since this method is an indirect calculation method, it is necessary to perform bench pulls and bench presses with a barbell or dumbbell, and calculate the maximum strength by the number of bench pulls and bench presses. Its accuracy is relatively poor, and the relative load on the human body is very large in the final stage. At the same time, this test cannot obtain the fastest speed to reach the maximum strength.

[0007] Although both of the above methods can perform maximum strength testing, they will generate a large load on the tester's body during the test, resulting in inaccurate test data. At the same time, the barbell or dumbbell may fall off as the tester's body becomes tired during the test, which poses a great safety hazard to the tester and makes it impossible to measure the time to obtain the maximum strength.

Specifically, the detection component 2 is arranged on the detection frame 12 for carrying out a weight detection on a tester. The Olympic rod 11 is arranged on the detection frame 12 and is located above the detection component 2. A pair of locking mechanisms 5 are provided, and a pair of locking mechanisms 5 are slidably penetrated on the detection frame 12. A pair of counterweight components 6 are provided, and a pair of counterweight components 6 are slidably penetrated on the detection frame 12 and are connected to the locking mechanisms 5 in a one-to-one correspondence. The two ends of the Olympic rod 11 are respectively connected by a pair of The locking mechanism 5 is slidably connected to the detection frame 12. When the tester is conducting the test, the tester pushes the Olympic bar 11 to move the height of the Olympic bar 11 to the required position, and quickly fixes it through the locking mechanism 5. After the fixation is completed, the tester performs bench press and bench pull on the Olympic bar 11 on the detection component 2. During the bench press and bench pull, the detection component 2 detects the reaction force during the bench press and bench pull, and calculates the maximum strength value of the tester. At the same time, the controller can retain the recorded values, so as to provide the tester with more accurate training plan values.

[0050] The detection assembly 2 of the utility model includes a force measuring platform 21, a sensor panel 23, a pressure sensor A22, a sensing panel 24, and a pull-rope sensor 9.

The pull-rope sensor 9 is arranged on the detection frame 12 and corresponds to the counterweight assembly 6. Specifically, the pressure sensor A22 is arranged at the four corners of the force measuring platform 21, a sensor panel 23 is arranged in the middle of the force measuring platform 21, the sensor panel 23 is located directly below the Olympic rod 11, the sensing panel 24 is arranged at both ends of the force measuring platform 21 and abuts against the pressure sensor A22, the pull-rope sensor 9 is arranged on the bracket 3, and the pull-rope sensor 9, the pressure sensor A22, the sensor panel 23 and the sensing panel 24 are electrically connected to the controller. Specifically, the tester performs bench press and bench pull on the Olympic bar 11 on the sensor panel 23, which facilitates the control of the tester's maximum strength. When the tester stands on the sensor panel 24, the output detected by the pressure sensor A22 at the four corners of the test bench is transmitted to the controller, and the controller determines whether someone is taking the test.

[0051] The force measuring platform 21 of the utility model is provided with pressure sensors B27 respectively abutting against the sensing panel 24, and pressure sensors C28 respectively abutting against the sensor panel 23.

By observing the values ​​in the control screen 37, it is possible to provide more accurate data support for formulating a training plan, and at the same time, control the time required to obtain the maximum force by analyzing the values ​​sensed by the pressure sensor A22, which is possible to provide more accurate data support for formulating a training plan.

When the same tester adjusts the height of the Olympic rod 11, the Olympic rod 11 drives the locking mechanism 5 to move. At the same time, the locking mechanism 5 pulls the counterweight block 62 to slide on the counterweight rod 61 through the pull rope. When the pull rope sensor 9 detects that the pull rope moves to a preset value, the pull rope sensor 9 transmits the detection result to the controller. The controller controls the locking mechanism 5 to lock, which can facilitate the adjustment of the height of the Olympic rod 11.

When the locking drive mechanism 52 contacts the clamping rod 516, the locking drive mechanism 52 pushes the clamping rod 516 to slide in the locking shell 514 mounting holes and the lock core 511 mounting holes, so that the clamping rod 516 contacts the detection frame 12 and fixes the locking assembly 51 on the detection frame 12.

[0063] The working principle of this utility model:

[0064] When in use, the locking member is first separated from the fixing member by starting the driving motor 53 to rotate in reverse, and the lock core 511 is moved on the height adjustment rod 4 by pushing or pulling the Ao rod 11.
