[0002] Compression testing evaluates an electronic product's ability to withstand various pressure conditions. Specifically, dedicated pressure testing equipment, such as a pressure tester or force sensor, is used to simulate actual pressure, either through point or surface pressure. Compression testing typically begins with light pressure and gradually increases to the device's tolerance limit. Pressure is applied at various locations, including the center, edges, and back of the screen.

[0003] The pressure resistance testing device for notebook computer shell is an auxiliary device for testing the pressure resistance of notebook computer shell, so as to better verify the use strength and service life of notebook computer shell.

[0025] In order to further illustrate the technical means and effects adopted by the present invention, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.

[0026] See also Figure 2-Figure 6 The utility model provides a pressure resistance detection device for a laptop computer, comprising a support frame 1, a loading plate 2 fixed on the top of the support frame 1, a support positioning mechanism 3 fixed on the support frame 1 and passing through the loading plate 2, and a pressure resistance detection mechanism 4 arranged above the loading plate 2; at least two guide grooves 21 are opened on the loading plate 2, the support positioning mechanism 3 comprises a fixed sleeve 30, a sliding piston plate 31, a push spring 32, a longitudinal sliding guide rod 33, a fixed ring frame 34, a laptop computer placement plate 35, a guide rod 36, a sliding guide seat 37 and a clamping positioning structure 38; the fixed sleeve 30 is fixed on the support frame 1, the sliding piston plate 31 It can slide along the inner wall of the fixed sleeve 30 and is fixed to one end of the longitudinal sliding guide rod 33; the push spring 32 is located in the fixed sleeve 30, with one end abutting the sliding piston plate 31 and the other end abutting the support frame 1; the fixed ring frame 34 is installed on the longitudinal sliding guide rod 33, and the other end of the longitudinal sliding guide rod 33 passes through the bearing plate 2 and is connected to the laptop placement plate 35; the guide rod 36 is located below the bearing plate 3, with one end hinged to the fixed ring frame 34, and the other end extends into the guide groove 21 and is hinged to the sliding guide seat 37; the sliding guide seat 37 can be slidably installed on the inner wall of the guide groove 21, and the clamping and positioning structure 38 is arranged above the bearing plate 2 and fixed on the sliding guide seat 37.

[0027] When testing the laptop computer's compressive strength tester of the present invention, the laptop computer to be tested is placed on the laptop computer placement plate 35. The laptop's own weight causes the longitudinal sliding guide rod 33 to slide downward, pulling the guide rod 36 to move the sliding guide seat 37 along the guide groove 21 from the edge of the support plate 2 toward the center, thereby driving the clamping and positioning structure 38 toward the center of the support plate to clamp the laptop computer that has fallen to the center of the support plate 2. After the test is completed, the laptop computer to be tested is removed from the laptop computer placement plate 35, and the laptop computer placement plate 35 is no longer under pressure. The spring 32 pushes the longitudinal sliding guide rod 33 upward, which in turn pushes the guide rod 36 to slide toward the edge of the support plate 2 until the clamping and positioning structure 38 is reset.

[0028] The compressive strength testing device for a laptop computer of the present invention is provided with a supporting positioning mechanism with a clamping positioning structure. When the laptop computer to be tested is placed into the supporting positioning mechanism, the weight of the laptop computer to be tested squeezes the supporting positioning mechanism, causing the supporting positioning mechanism to descend and driving the clamping positioning structure to move toward the laptop computer to be tested and clamp the laptop computer to be tested, thereby achieving rapid fixation of the laptop computer to be tested and preventing the laptop computer from sliding during the test, affecting the test or even causing damage to the laptop computer.

[0029] Preferably, the support plate 2 is provided with a retaining groove 22 corresponding to the laptop placement plate 35. When the weight of the laptop under test compresses the laptop placement plate 35, the laptop placement plate 35 descends and falls into the retaining groove 22, thereby positioning the laptop placement plate and ensuring that the laptop placement plate does not move during the test, facilitating the quick fixation of the laptop under test and further ensuring that the laptop under test does not slip during the test.

[0030] The guide grooves are provided in at least 2 or more. For details, please refer to Figure 2-4 6. In a preferred embodiment of the present invention, four guide slots 21 are arranged in an X-shape around the center of the support plate 2. When the laptop placement plate 35 is placed onto the support plate 2, the clamping and positioning structure 38 clamps the four corners of the laptop under test. The clamping and positioning structure 38 includes a base 381 and two clamping walls 382 extending from the base 381 perpendicular to the support plate 2. The two clamping walls 382 are perpendicular to each other. The base 381 is fixed to the sliding guide seat 37.

[0031] Figure 7The second embodiment of the present invention is shown. In this embodiment, two guide grooves 21' are arranged in a straight line around the center of the support plate 2'. When the laptop placement plate 35' is placed on the support plate 2', the clamping and positioning structure 38' clamps a pair of opposite corners of the laptop to be tested. The clamping and positioning structure 38' includes a base 381' and two clamping walls 382' extending from the base 381' in a direction perpendicular to the support plate 2'. The two clamping walls 382' are perpendicular to each other. The base 381' is fixed to the sliding guide seat 37'.

[0032] Figure 8 The third embodiment of the present invention is shown. In this embodiment, there are four guide grooves 21", which are distributed in a cross shape around the center of the carrier plate 2". When the laptop placement plate 35" falls onto the carrier plate 2", the clamping and positioning structure 38" clamps the four sides of the laptop to be tested. The clamping and positioning structure 38" includes a base 381" and a clamping wall 382" extending from the base 381" in a direction perpendicular to the carrier plate 2". The base 381" is fixed on the sliding guide seat 37".

[0033] Further, see Figure 4-5 The locking mechanism 393 is actuated by a spring 392 which is adapted to engage the locking member 394 and to engage the locking member 396. The locking member 393 is actuated by a spring 392 which is adapted to engage the locking member 396. The locking member 393 is actuated by a spring 392 which is adapted to engage the locking member 396.

[0034] As the longitudinal sliding guide rod 33 slides downward, the fixed ring frame 34 descends, pushing the limiting tooth plate 392 to tilt outward about the hinge seat 391. When the longitudinal sliding guide rod 33 stops sliding, the limiting tooth plate 392 returns inward due to the action of the torsion spring 393, locking the fixed ring frame 34 and the clamping and positioning structure 38, further ensuring that the laptop under test does not move during the test. After the test is completed, the locking of the fixed ring frame 34 is released by pulling the pull rod 394 to tilt the limiting tooth plate 392 outward about the hinge seat 391.

[0035] Further, see Figure 2-46. In a preferred embodiment of the present invention, the pressure resistance detection mechanism 4 includes a pair of parallel connecting frames 41, an extrusion assembly 42 fixed between the two connecting frames, a sliding rod 43 and a set of reset springs 44 arranged on the sliding rod 43 at each end of the connecting frame 41, a through hole 23 is provided on the edge of the supporting plate 2 for the sliding rod 43 to pass through, and the two ends of the reset spring 44 are respectively fixedly connected to the connecting frame 41 and the supporting plate 2.

[0036] When performing a compression test, the extrusion assembly 42 is pressed. The two connecting frames 41 are compressed and push the slide bar 43 to slide in the through hole 23 while squeezing the return spring 44. The extrusion assembly 42 then moves toward the surface of the laptop computer to complete the compression test.

[0037] Furthermore, the extrusion assembly 42 includes a top fixing frame 421 and an extrusion plate 422 . Both ends of the top fixing frame 421 are respectively fixed to the middle of the two connecting frames 41 , and the extrusion plate 422 is fixed in the middle of the top fixing frame 421 .

[0038] To sum up, the compressive strength testing device for laptop computers of the present invention is provided with a supporting positioning mechanism with a clamping positioning structure. When the laptop computer to be tested is placed in the supporting positioning mechanism, the weight of the laptop computer itself is used to squeeze the supporting positioning mechanism, so that the supporting positioning mechanism is lowered and the clamping positioning structure is driven to move toward the laptop computer to be tested until the laptop computer to be tested is clamped, thereby realizing rapid fixation of the laptop computer to be tested and avoiding the laptop computer to be tested from sliding during the test, affecting the test or even causing damage to the laptop computer.

[0039] As described above, for ordinary technicians in this field, various other corresponding changes and modifications can be made according to the technical solution and technical concept of the utility model, and all these changes and modifications should fall within the scope of protection of the claims of the utility model.
