Description

Technical Field

[0001] This invention relates to the field of sports force measurement technology, and in particular to an electronic force measurement device that is convenient and quick for statistical analysis. Background Technology

[0002] In training environments such as sports clubs, continuous exercise can increase a person's overall strength. Based on different strengths, these can be mainly divided into pushing force, pulling force, and striking force. Since the directions of these three forces are different, they need to be tested separately. This is mainly done through pressure sensors, and the strength can be assessed based on each person's height and weight to determine if they are up to standard.

[0003] The force measuring devices currently in use have the following drawbacks: 1. Currently used force measuring devices mainly use different sensors to detect different items individually. However, people of different heights release force at different heights. General force measuring devices do not have adaptive functions and lack the ability to adjust the force measuring height. 2. To prevent the device from moving under force, it needs to be pre-installed, which makes it inconvenient to quickly locate and use it according to the usage environment and weather factors, and the installation method is limited; 3. The impact caused by the strike directly affects the sensor, which can cause damage to the sensor itself over time, and it lacks the function of buffering the force measurement. Summary of the Invention

[0004] In view of this, the present invention provides a convenient and rapid electronic force measuring device, which has a support grip bar for measuring pull-up force. The support grip bar is raised to a position convenient for pull-ups, and then the support grip bar is used as a support bar for direct pull-up exercise. The downward force generated by the connecting cable, in conjunction with the reversal of the fixed pulley, is applied to the sliding frame. The force is measured and fed back using the rear pressure sensor A. The device uses a digital display of a wave meter to determine whether the force application method during the pull-up is correct.

[0005] This invention provides a convenient and rapid electronic force measuring device, specifically comprising: a combined outer casing, the right side of which has a rotating door structure; a vertical groove in the middle of the front side of the combined outer casing, within which a first lead screw is rotatably mounted; a first motor for driving the first lead screw is fixedly mounted on the upper front side of the interior of the combined outer casing, and the first motor and the first lead screw are connected by a bevel gear set; a lifting seat, which is threadedly connected to the first lead screw; a vertical groove in the middle of the left side of the combined outer casing, within which a second lead screw is rotatably mounted; a second motor for driving the second lead screw is fixedly mounted on the upper left side of the interior of the combined outer casing, and the second motor and the second lead screw are connected by a bevel gear set; a push-button switch for controlling the rotation direction of the first and second motors is also provided on the exterior of the combined outer casing; a height measuring plate, the top of which is fixedly mounted with a control frame, which slides on the front side of the combined outer casing and is threadedly connected to the second lead screw; and force measuring piston cylinders, the number of which is set to three axes, and the force measuring piston cylinders are fixedly mounted on the rear side of the combined outer casing.

[0006] Optionally, two sets of force-bearing plates are fixedly installed on the bottom front side of the combined outer box, and two sets of wedge-shaped pedals are fixedly installed on the top of each force-bearing plate, with the inclined surfaces of the front and rear wedge-shaped pedals adjacent to each other.

[0007] Optionally, the outer side of the combined outer casing is provided with an assembly hole, into which a threaded telescopic rod can be inserted.

[0008] Optionally, the inner bottom of the combined outer casing is provided with two sets of guide grooves; a connecting cable groove is fixedly provided on the inner bottom of the combined outer casing, an assembly power supply is slidably provided on the top of the connecting cable groove, and a T-shaped connector that matches and slides with the connecting cable groove is fixedly provided on the bottom of the assembly power supply. The T-shaped connector enables the assembly power supply to slide and connect with the connecting cable groove and maintain power supply; a pulley structure is also rotatably provided on both sides of the bottom of the assembly power supply, and the pulley structure matches the guide groove.

[0009] Optionally, the landing gear includes: sliding plates, with sliding plates fixedly installed on both the front and rear sides of the landing gear, and two sets of sliding plates slidingly mounted on the inner and outer sides of the front side of the combined outer casing in cooperation with guide rails; pressure sensor A, with pressure sensor A fixedly installed at the middle of the front end of the front sliding plate and the middle of the rear end of the rear sliding plate; guide rods, with guide rods fixedly installed on the front side of the front sliding plate and the rear side of the rear sliding plate; sliding frame, with a sliding frame slidably installed outside the front and rear guide rods, and a hand handle fixedly installed on the front side of the sliding frame; the sliding frame is integrally provided with a reinforcing rib structure for anti-deformation; pulley frame, with two sets of pulley frames fixedly installed at both ends of the bottom of the front sliding plate, and fixed pulleys rotatably installed at the front end of each pulley frame; a display device fixedly installed on the top of the front sliding plate; and connecting cable, with a connecting cable fixedly connected to the front bottom of the landing gear, and load-bearing handles fixedly installed at the bottom of the connecting cables on both sides.

[0010] Optionally, a head measuring plate is fixedly installed at the bottom of the height measuring plate, and a proximity switch is installed inside the head measuring plate; an infrared rangefinder is fixedly installed on the top left side of the combined outer box.

[0011] Optionally, the force-measuring piston cylinder includes: a force-measuring piston rod, which is slidably disposed in the middle of the rear side of the force-measuring piston cylinder, and a spring is disposed at the front end of the force-measuring piston rod; and a force-receiving piston, which is slidably disposed in the front end of the inner side of the force-measuring piston cylinder, and a pressure sensor B is fixedly disposed in the front end of the force-receiving piston, and a wire-threading support rod is fixedly disposed in the front end of the pressure sensor B, and the wire-threading support rod is fixedly disposed in the rear of the inner side of the combined outer casing.

[0012] Optionally, a weighbridge for measuring body weight is fixedly installed on the bottom left side of the combined outer casing.

[0013] Optionally, a positioning hole is provided on the inner bottom of the combined outer box, and a positioning stake is inserted into the positioning hole.

[0014] The beneficial effects are as follows: 1. This invention features a lifting seat, providing an adjustable force measurement height. The lifting seat can be moved up and down via a threaded drive, and the thread has self-locking properties for automatic fixation. A handheld lever provides a push-pull function; pulling the lever moves the sliding frame, applying pressure to the rear pressure sensor A to measure tension. Conversely, pushing the sliding frame forward applies pressure to the front pressure sensor A for thrust detection. Furthermore, a support grip can be used for pull-up force measurement. Raising the support grip to a convenient pull-up position allows for direct pull-up exercises. The downward force generated by the connecting cable, combined with the reversing motion of the fixed pulley, is applied to the sliding frame. The rear pressure sensor A provides force measurement and feedback, and the digital display of the wave meter allows for assessment of the correct force application during pull-ups.

[0015] 2. This invention has a dual installation function. The positioning stake is embedded in the ground by piercing the bottom of the combined outer box, thereby fixing the entire device and ensuring that the combined outer box cannot move horizontally, thus ensuring the measurement of subsequent tensile, thrust, and impact forces. The outer end of the threaded telescopic rod supports the indoor wall, thereby fixing the position of the combined outer box. This method allows for rapid indoor installation without the need for pre-drilling and damaging the ground structure. The threaded telescopic rod can be installed as needed. When the support distance is insufficient, the number of threaded telescopic rods can be increased to extend the support and ensure the support of the combined outer box.

[0016] 3. The impact force detection of this invention uses gas for buffering. By utilizing the gas to transmit force, the function of buffering force measurement is achieved. When the hammer strikes the force measuring piston rod, the force measuring piston rod moves backward under force, compressing the air inside the force measuring piston cylinder and applying pressure to the force-receiving piston. The force-receiving piston then feeds back the pressure to the pressure sensor B. The feedback is transmitted and displayed through the internal circuit of the wire support rod, thus completing the force measurement. The air-transmitted pressure method can provide a buffering effect and increase the service life of the pressure sensor B.

[0017] 4. This invention can also measure the specific gravity of the human body. The person being tested stands at the bottom of the weighing scale and uses the second motor to drive the second lead screw to rotate. The second lead screw drives the height measuring plate and the head measuring plate to descend through the threaded transmission. When the proximity switch in the head measuring plate approaches the head of the person being tested, it automatically stops. The distance the height measuring plate moves is measured by the infrared sensor. The height and weight of the human body, as well as whether the strength of the same body type is qualified, can be calculated at the same time. Attached Figure Description

[0025] The lifting seat 2 includes: a sliding plate 201, with sliding plates 201 fixedly installed on both the front and rear sides of the lifting seat 2, and the two sets of sliding plates 201 slidingly mounted on the inner and outer sides of the front side of the combined outer casing 1 in conjunction with guide rails; a pressure sensor A202, with a pressure sensor A202 fixedly installed at the middle of the front end of the front sliding plate 201 and the middle of the rear end of the rear sliding plate 201; a guide rod 203, with a guide rod 203 fixedly installed on the front side of the front sliding plate 201 and the rear side of the rear sliding plate 201; and a sliding frame 204, with the outer side of the front and rear guide rods 203 slidingly mounted. A sliding frame 204 is provided, and a hand handle 205 is fixedly installed on the front side of the sliding frame 204; the exterior of the sliding frame 204 is integrally provided with a reinforcing rib structure for anti-deformation; a pulley frame 206 is provided, and two sets of pulley frames 206 are fixedly installed at both ends of the bottom of the front sliding plate 201, and fixed pulleys 207 are rotatably installed on the front end of the pulley frame 206; a display device 3 is fixedly installed on the top of the front sliding plate 201; a connecting cable 208 is fixedly connected to the bottom front side of the lifting seat 2, and a load-bearing handle 209 is fixedly installed at the bottom of the connecting cables 208 on both sides.

[0026] Among them, a head measuring plate 501 is fixedly installed at the bottom of the height measuring plate 5, and a proximity switch is installed inside the head measuring plate 501; an infrared rangefinder 10 is fixedly installed on the top left side of the combined outer box 1.

[0027] The force-measuring piston cylinder 6 includes: a force-measuring piston rod 601, which is slidably disposed in the middle of the rear side of the force-measuring piston cylinder 6, and a spring is disposed at the front end of the force-measuring piston rod 601; and a force-receiving piston 602, which is slidably disposed in the front end of the inside of the force-measuring piston cylinder 6, and a pressure sensor B603 is fixedly disposed in the front end of the force-receiving piston 602, and a wire-threading support rod 604 is fixedly disposed in the front end of the pressure sensor B603, and the wire-threading support rod 604 is fixedly disposed in the rear of the inside of the combined outer casing 1.

[0028] Among them, a weighing scale 7 for measuring weight is fixedly installed on the bottom left side of the combined outer box 1.

[0029] The inner bottom of the combined outer box 1 is provided with a positioning hole, and a positioning stake 8 is inserted through the positioning hole.

[0030] like Figure 1-5 As shown, the height of the lifting seat 2 can be adjusted, thereby adjusting the height of the force measuring device to accommodate users of different heights for force measurement. The first motor 105 is started by using a push-button switch to drive the first lead screw 104 to rotate. The first lead screw 104 drives the lifting seat 2 to move up and down through the threaded transmission. When the lifting seat 2 is moved to a position suitable for the height of the tester, the force measurement can begin. The first motor 105 is a three-phase motor that can realize forward and reverse rotation. Its principle is that when symmetrical three-phase alternating current is passed through the three-phase stator winding, a rotating magnetic field is generated that rotates clockwise along the inner circle space of the stator and rotor at a synchronous speed n1. Since the rotating magnetic field rotates at a speed of n1, the rotor conductor is initially stationary. Therefore, the rotor conductor will cut the stator rotating magnetic field and generate an induced electromotive force. Since the two ends of the rotor conductor are short-circuited by the short-circuit ring, under the action of the induced electromotive force, an induced current will be generated in the rotor conductor that is basically in the same direction as the induced electromotive force. The current-carrying conductor of the rotor is subjected to electromagnetic force in the stator magnetic field. The electromagnetic force generates electromagnetic torque on the rotor shaft, driving the rotor to rotate along the direction of the rotating magnetic field. Therefore, different sequences can be switched by triggering the KM contactor through two push-button switches. Method for testing tensile force: Hold the handle 205 with both hands, step on the wedge-shaped pedal 102 on the front, and pull the handle 205 with force. This will cause the sliding frame 204 to move as a whole. The sliding frame 204 will then apply pressure to the pressure sensor A202 on the rear side. The pressure sensor A202 will then provide pressure feedback and transmit it to the display device 3 for digital display, thereby measuring the tensile force of the tester. The method for testing thrust is as follows: Hold the hand lever 205 with both hands, step on the wedge-shaped pedal 102 on the front side, and pull the hand lever 205 with force. This will cause the sliding frame 204 to move as a whole. The sliding frame 204 will then apply pressure to the pressure sensor A202 on the rear side. The pressure sensor A202 will then provide pressure feedback and transmit it to the display device 3 for digital display, thereby measuring the pull force of the tester. The detection of thrust and pull forces can be extended to include force measurement during the switching between thrust and pull forces.

[0031] Example 2: Based on Example 1, such as Figure 1-7 As shown, the height of the support bar 209 can be adjusted, and the support bar 209 can be used as a pull-up bar to perform a pull-up strength test. Simply raise the lifting seat 2 so that the support bar 209 is raised to a position that is convenient for pull-ups. Using the support bar 209 as a support for direct pull-up exercises, similarly, force measurement can also be performed on other single bar exercises. The pull-down force generated by the support bar 209 and the connecting cable 208, combined with the reversal of the fixed pulley 207, is applied to the sliding frame 204. Then, the rear pressure sensor A202 is used to measure the force and provide feedback. Using the digital display of the wave meter, it can be determined whether the force application method during the pull-up process is correct. The central axis of the fixed pulley 207 is fixed. The function of the fixed pulley 207 is to change the direction of the force, but it cannot save effort. When pulling heavy objects, the fixed pulley 207 can be used to change the direction of the applied force to the direction of easy output. When using the fixed pulley 207, the distance pulled by the applied force is equal to the distance the object rises. It neither saves nor wastes effort. The tension at both ends of the rope is equal, so the output force is equal to the input force. Neglecting friction, the mechanical efficiency of the fixed pulley 207 is close to 1. Therefore, the fixed pulley 207 can switch the lateral force to the vertical force without changing the value.

[0032] Example 3: Based on Example 1, such as Figure 4-5 As shown, pressure sensor B603 is a component used to detect impact force; When testing the impact force, the force-measuring piston rod 601 is directly struck. The force-measuring piston rod 601 moves backward under the force, compressing the air inside the force-measuring piston cylinder 6 and applying pressure to the force-receiving piston 602. The force-receiving piston 602 then feeds the pressure back to the pressure sensor B603. The feedback is transmitted and displayed through the internal wiring of the wire support rod 604, thus completing the force measurement. The method of transmitting pressure through air can provide a buffering effect and increase the service life of the pressure sensor B603. When an impact force is applied to the force-measuring piston rod 601, it is simultaneously fed back to the pressure sensor B603. During this process, the impact force is reduced by the buffering effect of air and spring, but this does not affect the final test and comparison. Since the buffering force generated by different people is also different, it is only necessary to set a constant value. For example, the impact force can be set to 100N using mechanical equipment, and the value of the impact force feedback can be adjusted to 100N. By adjusting proportionally, the impact force generated by different people will also be adaptively adjusted to ensure the accuracy of the value. The force measuring piston cylinder 6 consists of three sets, which can provide a comparison effect. In addition, the upper and lower span of the front end of the force measuring piston rod 601 can be increased to ensure that the measurement can be performed normally regardless of the height difference, depending on the different positions of the force applied by each person.

[0033] Example 4: Based on Example 1, such as Figure 2 and Figure 8 As shown, the present invention has two installation methods, which can be adjusted according to changes in indoor and outdoor conditions; Generally, it is convenient to install outdoors, but it cannot be used in rainy weather. Outdoors, holes can be pre-drilled in the ground or holes can be directly drilled using positioning stakes 8. Finally, the positioning stakes 8 are inserted into the ground through the bottom of the combined outer box 1 to achieve overall fixation of the device. According to the force measurement requirements, it is only necessary to fix the combined outer box 1 in the horizontal direction. However, if it is installed indoors, the combined outer box 1 is placed in a suitable position, and then multiple sets of threaded telescopic rods 9 are directly installed. The outer ends of the threaded telescopic rods 9 are used to support the indoor walls to fix the position of the combined outer box 1. This method can achieve quick indoor installation without pre-drilling and damaging the ground structure. The threaded telescopic rod 9 is installed as needed, and when the threaded telescopic rod 9 is not close enough to the wall, the number of threaded telescopic rods 9 can be increased for axial splicing to ensure support for the combined outer box 1.

[0034] The specific usage and function of this embodiment: In this invention, when in use, the display device 3 provides information display function, and multiple sets of display devices 3 can be set to display different functions separately according to usage needs; Depending on the environment, first fix the overall position of the device. If it is in a location where piling is possible, drill holes in the ground beforehand or directly drill holes using positioning stakes 8. Finally, insert the positioning stakes 8 through the bottom of the combined outer box 1 into the ground to fix the overall position of the device. According to the force measurement requirements, it is only necessary to fix the horizontal direction of the combined outer box 1. If the force measurement is carried out indoors, place the combined outer box 1 in a suitable position, and then directly install multiple sets of threaded telescopic rods 9. Use the outer ends of the threaded telescopic rods 9 to support the indoor wall to fix the position of the combined outer box 1. This method can achieve quick installation indoors without the need to pre-drill holes to damage the ground structure. According to the test requirements, the first motor 105 is started to drive the first lead screw 104 to rotate. The first lead screw 104 drives the lifting seat 2 to move up and down through the thread transmission. When the lifting seat 2 is moved to a position suitable for the height of the tester, the force measurement can begin. When testing the tensile force, simply hold the hand handle 205 with both hands, step on the wedge-shaped pedal 102 on the front side, and pull the hand handle 205 with force. This will cause the sliding frame 204 to move as a whole. The sliding frame 204 will then apply pressure to the pressure sensor A202 on the rear side. The pressure sensor A202 will then provide pressure feedback and transmit it to the display device 3 for digital display, thereby measuring the tensile force of the tester. When testing the thrust, step on the wedge-shaped pedal 102 on the back and push the hand lever 205 to move the sliding frame 204 backward. The pressure is applied to the pressure sensor A202 on the front, and the feedback is transmitted to the display device 3 for digital display, thereby measuring the thrust of the tester. Furthermore, the support bar 209 can be used to measure the force during pull-ups. The lifting seat 2 is raised so that the support bar 209 is raised to a position that facilitates pull-ups. Then, the support bar 209 is used as a support for direct pull-up exercises. The downward force generated by the support bar 209 and the connecting cable 208, combined with the reversal of the fixed pulley 207, is applied to the sliding frame 204. The rear pressure sensor A202 is used to measure the force and provide feedback. The digital display of the wave meter can be used to determine whether the force application method during the pull-up process is correct. The person being tested stands at the bottom of the weighing scale 7, and then the second motor 107 is started to drive the second lead screw 106 to rotate. The second lead screw 106 drives the height measuring plate 5 and the head measuring plate 501 to descend through the thread transmission. When the proximity switch in the head measuring plate 501 approaches the head of the person being tested, it automatically stops. The distance moved by the height measuring plate 5 is measured by the infrared sensor, and the height and weight of the person can be calculated at the same time. When impact force needs to be tested, the force-measuring piston rod 601 is struck directly with a hammer. The force-measuring piston rod 601 moves backward under the force, compressing the air inside the force-measuring piston cylinder 6 and applying pressure to the force-receiving piston 602. The force-receiving piston 602 then feeds the pressure back to the pressure sensor B603. The feedback is transmitted and displayed through the internal wiring of the wire support rod 604, thus completing the force measurement. The method of transmitting pressure through air can provide a buffering effect and increase the service life of the pressure sensor B603. The power supply 4 is a sliding mount, which can be directly removed for charging or replacement.
