[0051] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0052] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0053] Combine Figure 1 and Figure 2As shown, an embodiment of the present disclosure provides a testing device, which includes a fixing member 1, a guide member 2, and a force-applying member 3; the fixing member 1 has a fixing station 11 for fixing a device under test; the guide member 2 has a plurality of guide rail segments 21 arranged along different directions, and the plurality of guide rail segments 21 intersect to form at least one track switching point 201; the force-applying member 3 is adjustably arranged in the guide rail segment 21 and can be connected to the device under test in the fixing station 11;

[0054] Among them, the force-applying member 3 can move along each guide rail segment 21 respectively, and can switch between different guide rail segments 21 through the track switching point 201; the force-applying member 3 can also fix the test point in each guide rail segment 21 respectively to apply test force to the device under test from different directions.

[0055] The testing device provided in the embodiments of the present disclosure can be specifically but not limited to being used for testing the tensile strength of a safety cable in a laptop computer. This example will be used to illustrate the usage process.

[0056] When the testing device is used, the laptop computer to be tested is first fixed in the fixed position 11 of the fixing member 1, and then the force-applying member 3 is correspondingly set in the guide rail section 21 of the guide member 2, and pre-tightened to the laptop computer to be tested. Then, the force-applying member 3 is moved to the test point of the guide rail section 21, and the test tension can be applied to the laptop computer to be tested by the force-applying member 3, so that the tensile strength test of the laptop computer to be tested in the first position by the force-applying member 3 can be completed; then, the force-applying member 3 can temporarily stop outputting the test tension, and move to the track switching point 201, and switch to another guide rail section 21 through the track switching point 201, and continue to apply the test tension to the laptop computer to be tested after entering the test point of the guide rail section 21, so that the tensile strength test of the laptop computer to be tested in the second position by the force-applying member 3 can be completed; thereafter, the force-applying member 3 can perform tensile strength tests on the laptop computer to be tested in the third position, the fourth position, etc. at the test points of the remaining guide rail sections 21 in the same manner.

[0057] In the test device provided by the embodiment of the present disclosure, the force-applying member 3 can flexibly switch its own test position by forming a track switching point 201 through the intersection of multiple guide rail segments 21, so that the force-applying member 3 can quickly complete the tensile strength test of the laptop computer to be tested in different orientations, and there is no need to disassemble and re-fix the laptop computer to be tested during multiple test processes, which greatly simplifies the test process and improves the test efficiency.

[0058] In one embodiment, the guide rail segment 21 includes a first rail segment 211, a second rail segment 212, a third rail segment 213 and a fourth rail segment 214; one end of the first rail segment 211 is connected to the track change point 201, and the other end is connected to the base 22 in the guide member 2; one end of the second rail segment 212 is connected to the track change point 201, and the other end is connected to the base 22; one end of the third rail segment 213 is connected to the track change point 201 and is arranged opposite to the first rail segment 211, and the other end is connected to the base 22; one end of the fourth rail segment 214 is connected to the track change point 201 and is arranged opposite to the second rail segment 212, and the other end is connected to the base 22; wherein, the force member 3 can switch to any one of the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214 in the track change point 201.

[0059] Specific, combined Figure 2 To further explain in detail, the guide rail segment 21 is specifically configured to include a first rail segment 211, a second rail segment 212, a third rail segment 213 and a fourth rail segment 214, and each of the four rail segments has an end connected to the track change point 201, and the other end connected to the base 22 in the guide member 2. In this way, when the force member 3 is in any rail segment, as long as it reaches the track change point 201, it can switch to any one of the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214, thereby greatly improving the switching efficiency of the force member 3 between different rail segments.

[0060] In addition, it is worth mentioning that the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214 can be specifically distributed in a "cross" shape, and are distributed in the front, rear, left and right directions relative to the base 22. In this way, the force-applying member 3 can perform tensile strength tests on the relative front side, relative rear side, relative left side and relative right side of the notebook to be tested.

[0061] Of course, the guide rail segment 21 can also be specifically configured to have a larger number of sub-rail segments, for example but not limited to, eight sub-rail segments can be configured, distributed in a "M" shape.

[0062] In one embodiment, the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214 are respectively configured as arc-shaped rail segments; the first rail segment 211 and the third rail segment 213 can correspondingly form an arc-shaped rail segment group protruding away from the fixing member 1, and the second rail segment 212 and the fourth rail segment 214 can correspondingly form a protruding arc-shaped rail segment group away from the fixing member 1.

[0063] Specific, combined Figure 2To further explain in detail, the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214 can be set as arc-shaped rail segments with the same radius and an arc of 90°, and the track change point 201 is located at the central intersection of the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214.

[0064] In this way, the first rail segment 211 and the third rail segment 213 can form a semicircularly convex arc rail segment group, and the second rail segment 212 and the fourth rail segment 214 can form a semicircularly convex arc rail segment group. When the force-applying member 3 switches to the first rail segment 211, the second rail segment 212, the third rail segment 213 or the fourth rail segment 214 at the center rail switching point 201, the distance between the force-applying member 3 and the laptop computer under test can always remain unchanged. On the one hand, the smoothness of the force-applying member 3 when switching between different rail segments can be improved. On the other hand, the switching of the force-applying member 3 between different rail segments will not cause a sudden increase or decrease in the pre-tightening connection force between the force-applying member 3 and the laptop computer under test, thereby avoiding accidental damage to the laptop computer under test during the switching process of the force-applying member 3.

[0065] In one embodiment, the base 22 is configured as an annular body, and the first rail segment 211 , the second rail segment 212 , the third rail segment 213 and the fourth rail segment 214 are arranged in an annular array about the central axis of the base 22 .

[0066] Specific, combined Figure 2 To further explain in detail, the base 22 is specifically configured as an annular body, and the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214 are arranged in a circular array about the central axis of the base 22, so that the base 22 and the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214 can together form a hemispherical frame structure, and the test points of the first rail segment 211, the second rail segment 212, the third rail segment 213 and the fourth rail segment 214 can all be set as end points connected to the base 22.

[0067] The specific connection and setting mode of the base 22 and the guide rail segment 21 can make the overall structure of the guide member 2 more compact and occupy less space without affecting the flexible and rapid switching of the force-applying member 3 between different rail segments.

[0068] In one embodiment, the guide rail segment 21 is respectively provided with a limiting guide edge 215 along its own extension direction; a limiting slot 216 is correspondingly provided in the limiting guide edge 215; the force-applying member 3 has a limiting column 31 limitedly set in the limiting slot 216, and when the force-applying member 3 moves along the guide rail segment 21, the limiting column 31 moves accordingly along the limiting slot 216.

[0069] Specific, combined Figure 2 and Figure 4 To further explain in detail, the guide rail segment 21 can be specifically set to be a steel arch plate shape, and the limiting guide edge 215 can be specifically set in two parallel and spaced apart along the extension direction (bending direction) of the guide rail segment 21, and respectively located on the outer wall of the guide rail segment 21, and the limiting groove 216 can be specifically set through the limiting guide edge 215 and extend accordingly along the limiting guide edge 215, so that the two limiting columns 31 in the force member 3 that are set back to back to each other can be respectively inserted into the limiting groove 216 in the limiting guide edge 215, and the limiting movement of the force member 3 in the guide rail segment 21 is realized by moving the limiting column 31 along the limiting groove 216.

[0070] The specific arrangement of the limiting guide edge 215 , the limiting notch 216 and the limiting column 31 has a simple structure and can effectively limit the movement trajectory of the force applying member 3 in the guide rail section 21 without affecting the smooth movement of the force applying member 3 .

[0071] In one embodiment, the force-applying member 3 further includes a power ball wheel 32 ; the power ball wheel 32 is disposed at the bottom of the force-applying member 3 and rolls against the guide rail segment 21 ; the power ball wheel 32 can roll along the surface of the guide rail segment 21 to drive the force-applying member 3 to move along the guide rail segment 21 .

[0072] Specific, combined Figure 4 To further explain in detail, the power ball wheel 32 can be specifically arranged at the bottom of the force-applying member 3 and be arranged as a universal ball wheel, so that the force-applying member 3 can roll and abut against the guide rail segment 21 through the power ball wheel 32. When the power ball wheel 32 rolls along the surface of the guide rail segment 21, it can drive the force-applying member 3 to move along the guide rail segment 21.

[0073] In addition, when the force member 3 moves to the track change point 201, the power ball wheel 32 only needs to change its own rolling direction accordingly to adjust the moving direction of the force member 3, thereby quickly realizing the function of the force member 3 to change the track at the track change point 201.

[0074] In one embodiment, the force-applying member 3 also includes a tension rope 33; one end of the tension rope 33 is connected to the torque member in the force-applying member 3, and the other end can extend out of the force-applying member 3 and be connected to the device to be tested in the fixing member 1; the torque member can apply a test force to the device to be tested by rotating and winding the tension rope 33.

[0075] Specific, combined Figure 1 and Figure 4To further explain in detail, the tension rope 33 in the force member 3 can be specifically but not limited to being set as a steel wire rope, and the torque member in the force member 3 can be specifically set as a stepper motor, so that the force member 3 can reel in or unreel the tension rope 33 accordingly by controlling the forward and reverse output angles of the stepper motor, so as to realize the function of controlling the force member 3 to apply different test tensions to the equipment to be tested.

[0076] Of course, the aforementioned torsion member may also be configured as other types, such as a constant force torsion spring.

[0077] In one embodiment, the fixing station 11 includes two clamping plate groups 111 and fasteners 112 that are spaced apart from each other; a clamping area for clamping and fixing the device to be tested is formed between the two clamping plate groups 111, and the fasteners 112 are used to adjust the spacing between the two clamping plate groups 111 to change the clamping force on the device to be tested.

[0078] Specific, combined Figure 3 To further explain in detail, two clamping plate groups 111 are set at intervals from each other in the fixed workstation 11, so that the two sides of the laptop computer to be tested can be clamped respectively by the two clamping plate groups 111, and the fasteners 112 can also be used to adjust the distance between the two clamping plate groups 111 to change the clamping force of the clamping plate groups 111 on the laptop computer to be tested.

[0079] The fastener 112 may be specifically but not limited to a screw-nut clamping mechanism, which drives the nut to move in translation by twisting the screw, thereby changing the distance between the two clamping plate groups 111 .

[0080] In one embodiment, the fixing member 1 also includes an adjusting member group 12; the adjusting member group 12 includes an adjusting member 121 and a power member 122; the adjusting member 121 is used to install the clamping plate group 111; the power member 122 is connected to the clamping plate group 111 through a transmission mechanism, and can drive the adjustment clamping plate group 111 to the setting position of the adjusting member 121.

[0081] Specific, combined Figure 3 To further explain in detail, an adjusting member group 12 is also provided in the fixing member 1, and the adjusting member group 12 includes an adjusting member 121 and a power member 122. The adjusting member 121 can be used to install the clamping plate group 111. The adjusting member 121 can be specifically set to a U-shaped card plate body, and a corresponding card slot is opened in the card plate body. The clamping plate group 111 can be correspondingly plugged into the U-shaped empty area of the card plate body, and the clamping plate group 111 can be correspondingly provided with a card head protruding and inserted into the card slot. In this way, when the power member 122 drives the clamping plate group 111 to move in the adjusting member group 12 through the transmission mechanism, the clamping plate group 111 can move along the extension direction of the slot body of the card slot, thereby changing the setting position of the clamping plate group 111 in the adjusting member 121.

[0082] The above-mentioned power member 122 can be specifically configured as a driving motor, and the transmission mechanism can be configured as a screw-nut mechanism, so that the rotation output by the driving motor can be converted by the screw-nut mechanism into a translational motion that drives the clamping plate group 111 to move.

[0083] The specific arrangement of the adjusting member group 12 has the beneficial effects of being simple in structure and being able to flexibly adjust the position of the clamping plate group 111 in the adjusting member 121 .

[0084] In one embodiment, the test device further includes a control box 4 ; the control box 4 is electrically connected to the force applying member 3 and the adjusting member group 12 , respectively, for electrically controlling and adjusting the working states of the force applying member 3 and the adjusting member group 12 .

[0085] Specific, combined Figure 1 To further explain in detail, the above-mentioned control box 4 can be connected to the torque member in the force member 3, or the power member 122 in the adjustment member group 12 through wireless or wired electrical connection, and the program in the control box 4 can be used to automatically control the working status of the force member 3 and the adjustment member group 12, thereby further improving the degree of automation of the test device.

[0086] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0087] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.
