[0028] See also Figure 1-4 The present application provides a grip testing device, including a grip testing assembly 1 and at least two holding devices 2, wherein the grip testing assembly 1 is rotatably connected to the at least two holding devices 2, and the holding devices 2 include a telescopic mechanism 203, a first grip plate 201, and a second grip plate 202, wherein the telescopic mechanism 203 is connected to the first grip plate 201, and the telescopic mechanism 203 is used to adjust the relative distance between the first grip plate 201 and the second grip plate 202. By adjusting the telescopic mechanism 203, the telescopic mechanism 203 can change the relative distance between the first grip plate 201 and the second grip plate 202, thereby adapting to hands of different sizes. In the process of measuring grip, the user can measure the grip of both hands through the holding device 2, and the holding device 2 can rotate relative to the grip testing assembly 1, thereby facilitating storage and carrying.

[0029] Specifically, the user places the hand between the first grip plate 201 and the second grip plate 202, and the telescopic mechanism 203 can adjust the relative distance between the first grip plate 201 and the second grip plate 202 to adapt to different hand sizes. The grip frame includes the first grip plate 201, the second grip plate 202 and other relatively parallel grip plates.

[0030] Specifically, the grip strength testing assembly 1 includes a housing 101 , a pressure sensing assembly, and the like.

[0031] In this embodiment, the pressure sensing component is a thin film pressure sensor 102 .

[0032] Specifically, the holding device 2 is used for the user to place his hands, and the holding device 2 is used to directly obtain the user's grip strength signal, and the grip strength signal is transmitted to the grip strength testing component 1 and converted into a grip strength value.

[0033] In this embodiment, the grip testing device includes two gripping devices 2. The gripping device 2 includes a first gripping plate 201, a second gripping plate 202, a telescopic mechanism 203, a transmission component 205 and a driving component 204.

[0034] In one embodiment, the grip strength testing device includes three holding devices 2. In this case, the grip strength testing device can test the grip strength data of two or three persons.

[0035] Furthermore, the holding device 2 is symmetrically arranged with respect to the grip strength test assembly 1. By symmetrically arranging the holding device 2, the user can apply force more evenly to the two holding devices 2, avoiding inaccuracy of the test result caused by bias to one side, and can also reduce the user's discomfort during the grip strength test and improve the comfort of the test.

[0036] Preferably, the distance between the first holding device 2 and the upper top surface of the grip strength testing assembly 1 is equal to the distance between the second holding device 2 and the upper top surface of the grip strength testing assembly 1 .

[0037] Specifically, it also includes a rotating mechanism 3, which includes a rotating shaft and a buckle 303, and the rotating shaft and the buckle 303 are arranged between the grip strength test assembly 1 and the holding device 2.

The user can adjust the grip strength test posture and angle through the rotating mechanism 3 to improve the comfort of the test and the user experience. When the user does not use the grip strength test device, the grip strength test device can be folded to reduce the storage space.

[0038] In one embodiment, the rotating shaft is a cylindrical rotating shaft. A portion of the buckle 303 is connected to the rotating shaft 301 , and another portion of the buckle 303 is connected to the grip strength testing assembly 1 .

[0039] Specifically, the grip strength test assembly 1 includes a thin film pressure sensor 102 and a data interface 103. The thin film pressure sensor 102 is connected to the data interface 103. The data interface 103 is used to transmit the pressure signal obtained by the thin film pressure sensor 102. By setting the thin film pressure sensor 102 and the data interface 103, the pressure signal of the user during the grip strength test can be monitored and recorded in real time, thereby providing more accurate and objective test results. The data interface 103 can record and store these pressure signals, and can also perform data processing and calculation, such as calculating the grip strength, generating a curve graph, etc.

[0040] In one embodiment, the data interface 103 can be connected to an external display device 105 or a mobile phone or other device.

[0041] It can be understood that the thin film pressure sensor 102 is a commonly used pressure measuring device. The thin film pressure sensor 102 detects and measures pressure by placing a thin film material in a stress-bearing area and utilizing changes in resistance, capacitance or inductance and other properties of the thin film after the film is stressed. The thin film pressure sensor 102 includes a thin film material, a supporting structure, and a circuit connector. The working principle of the thin film pressure sensor 102 is based on the deformation and electrical property changes of the thin film material when subjected to external pressure. Common thin film materials include silicon, polyester film, metal film, and the like. When external pressure is applied to the surface of the film, the film bends or stretches, causing changes in electrical properties such as resistance, capacitance or inductance inside the film.

[0042] Optionally, the thin film pressure sensor 102 may be a resistive thin film pressure sensor 102 , a capacitive thin film pressure sensor 102 , or an inductive thin film pressure sensor 102 , and the like.

[0046] Furthermore, the second grip plate 202 is arranged on a side away from the telescopic mechanism 203, and the second grip plate 202 is a wavy grip plate. By arranging the second grip plate 202 on a side away from the telescopic mechanism 203, the movement of the telescopic mechanism 203 is prevented from interfering with the grip test, and the wavy grip plate is used to fit the curve of the user's hand, thereby improving the comfort of the test and the user experience.

[0052] In another embodiment, the anti-slip coating is a coating provided with anti-slip threads.

[0053] Furthermore, the rotating mechanism 3 further includes a groove 302, and the rotating shaft can rotate in the groove 302. The groove 302 limits the moving range of the rotating shaft, so that the rotating shaft rotates within the fixed track, reducing the error caused by unnecessary lateral movement, thereby improving the accuracy of the test. The groove 302 can also reduce the direct contact between the rotating shaft and other components, reduce wear and friction, thereby extending the service life of the rotating mechanism 3 and reducing maintenance costs.

[0054] In one embodiment, a flexible material is laid in the groove 302 , and the flexible material is in contact with the rotating shaft to reduce the loss of the rotating shaft.

[0055] In one embodiment, the length of the rotating shaft 301 is less than or equal to the length of the groove 302 , and the outer diameter of the rotating shaft 301 is less than or equal to the width of the groove 302 .

[0056] Furthermore, it also includes an indicator device 104, which is electrically connected to the film pressure sensor 102. The indicator device 104 is electrically connected to the film pressure sensor 102, and can monitor the use status and power usage status of the grip strength test device in real time, thereby facilitating the maintenance and repair of the grip strength test device.

[0058] In another embodiment, the indicator device 104 may be an indicator light, and the color state of the indicator light is used to indicate the use state of the grip strength testing device. A green indicator light indicates that the device can be used normally, a red indicator light indicates that the device is low on power, and an off indicator light indicates that the device is faulty.

[0060] Specifically, the driving device 107 is disposed in the grip strength testing assembly 1 , the driving device 107 is electrically connected to the pressure film sensor, and the driving device 107 is electrically connected to the indicating device 104 .

[0061] In one embodiment, the grip strength testing device further includes a switch 108, and the switch 108 is used to turn on and off the grip strength testing device.

[0062] Furthermore, it also includes a display device 105 and a storage device 106. The display device 105 is used to display real-time grip strength test data, and the storage device 106 is used to store historical grip strength test data. The user can adjust the grip strength in time according to the data changes on the display device 105 to improve the accuracy and effect of the test. The storage device 106 can store historical grip strength test data, including grip strength data at different time points, user's grip strength change trend and other information.

[0063] Optionally, the display device 105 may be integrated with the grip strength testing assembly 1 , or may be separately arranged outside the grip strength testing assembly 1 .

[0067] First, unfold the folded grip strength test device to the third direction along the groove 302 through the rotating shaft 301, turn on the switch 108 to start the grip strength test, and determine whether the device can be used normally through the indicating device 104;

[0068] Then, when the indicator device 104 displays a normal state, the user places the hand on the grip frame, and by adjusting the button, the driving component 204 controls the telescopic mechanism 203, thereby adjusting the relative distance between the first grip plate 201 and the second grip plate 202 to adapt to the user's hand curve. The user exerts force on the first grip plate 201 to obtain a grip signal, and the transmission component 205 transmits the grip signal to the grip test component 1, and the grip signal is converted into a grip value on the display device 105 for easy viewing; the detected grip value is stored in the storage device 106, and when the historical grip value needs to be transmitted, the data interface 103 is connected to an external mobile device;
