Description

[0002] Laptop manufacturers usually fix rubber pads of a certain thickness at the four corners of the bottom of the laptop to prevent slipping and support the laptop to assist in heat dissipation. During the long-term use of the laptop, the rubber pads will always have some friction. When worn to a certain extent, the laptop pads lose their function as pads, which makes the user experience worse and more or less affects the normal use of the laptop. Therefore, during the design and production process of laptops, it is necessary to test the laptop pads to test the wear resistance of the laptop pads and ensure that the laptop pads have good wear resistance when delivered for use. However, the test materials of conventional laptop pad wear test devices are relatively single, and cannot effectively simulate the friction loss of the laptop pads in various usage scenarios, resulting in a large difference between the test results and the actual situation, and unable to allow designers to effectively understand the wear resistance of the laptop pads in actual use.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] like Figure 1-6 As shown, the wear resistance testing device for the notebook foot pad provided in this embodiment includes a base 1, a clamping mechanism 2, a travel mechanism 3 and a testing mechanism 5.

[0040] See also Figure 1 The clamping mechanism 2 is installed on the top of the base 1 and is used to clamp the laptop computer.

[0041] Specifically, the clamping mechanism 2 includes two mounting plates 21 arranged on the front and rear sides of the top of the base 1, and the two mounting plates 21 are respectively threaded with adjusting screws 22. The ends of the two adjusting screws 22 close to each other are respectively provided with clamps 23 slidably installed on the top of the base 1. It should be noted that the adjusting screws 22 are rotatably connected to the clamps 23, a sliding groove is provided on the top of the base 1, and a sliding block slidably connected to the sliding groove is provided at the bottom of the clamp 23. By rotating the adjusting screws 22, the distance between the two clamps 23 can be changed, and the laptop computer can be clamped between the two clamps 23. Furthermore, the two clamps 23 are respectively provided with guide rods 24 sliding through the corresponding mounting plates 21 on the side away from each other, so that the clamps 23 can keep moving smoothly.

[0042] The travel mechanism 3 is installed on the top of the base 1 and a substrate 4 is installed thereon. The travel mechanism 3 can control the substrate 4 to translate above the clamping mechanism 2 .

[0043] Specifically, the travel mechanism 3 includes a first linear module 31 and a second linear module 32, and sliders are slidably installed on the first linear module 31 and the second linear module 32. The two first linear modules 31 are installed parallel to each other on both sides of the clamping mechanism 2, and the second linear module 32 is installed above the sliders of the two first linear modules 31 and is perpendicular to the first linear module 31. The substrate 4 is installed on the slider of the second linear module 32. When in use, the first linear module 31 and the second linear module 32 are responsible for the horizontal movement of the substrate 4 in two directions, respectively, so that the substrate 4 can be horizontally moved above the laptop to above the foot pad. It should be noted that the first linear module 31 and the second linear module 32 are both existing technology products, and both have sliders that can move linearly, so their specific structures will not be described in detail.

[0044] See also Figure 1-Figure 4The test mechanism 5 includes a telescopic cylinder 51, a test seat 52, a turntable 53, a switching component 54 and a locking component 55. The telescopic cylinder 51 can be a hydraulic cylinder or an electric telescopic cylinder. The telescopic cylinder 51 is installed on the front side of the base plate 4. The telescopic shaft end of the telescopic cylinder 51 faces downward and is installed with the test seat 52. The bottom of the test seat 52 is provided with a mounting groove 521. The turntable 53 is rotatably installed in the mounting groove 521. A plurality of test heads 531 of different materials are evenly distributed around the edge of the turntable 53. The switching component 54 is used to drive the turntable 53 to rotate so that each test head 531 can face directly below the test seat 52. The locking component 55 can lock the turntable 53 immovably.

[0045] In specific use, by starting the telescopic cylinder 51, the bottom test head 531 can be moved closer to or away from the notebook pad to perform wear resistance test or switch the test head 531. By driving the turntable 53 to rotate through the switching component 54, the test heads 531 of different materials can be rotated toward the bottom of the test seat 52, and then the test heads 531 with different friction coefficients can be used to perform wear resistance test on the notebook pad, simulating the friction loss of the notebook pad in various usage scenarios, so that the test results can be closer to the actual usage, which helps designers understand the actual wear resistance of the notebook pad and provides assistance for the research and development of the notebook pad. The device can quickly switch different test heads 531, is easy to operate, and can effectively improve the test efficiency.

[0046] like Figure 4 As shown, specifically, the switching assembly 54 includes a motor 541 and a ring gear 542. The ring gear 542 is arranged around one side of the edge of the turntable 53. The motor 541 is embedded in the test seat 52, and its output shaft end extends into the mounting groove 521 and is installed with a first gear 543 that meshes with the ring gear 542. By starting the motor 541 and then utilizing the meshing transmission of the first gear 543 and the ring gear 542, the test head 531 can be quickly switched.

[0047] Preferably, a plurality of threaded holes 533 are evenly distributed around the edge of the turntable 53, and the test head 531 can be screwed into the threaded holes 533, thereby realizing a detachable connection between the test head 531 and the turntable 53, and facilitating the disassembly and replacement of a worn test head 531.

[0048] Furthermore, one side of the turntable 53 is evenly distributed with a plurality of fixing grooves 532 corresponding to each test head 531. The locking assembly 55 includes a latch 551 and an abutment plate 552. A socket 522 which can coaxially correspond to a certain fixing groove 532 is provided on one side of the test seat 52. When a certain test head 531 is directed toward directly below the test seat 52, the socket 522 can coaxially correspond to one of the fixing grooves 532. The latch 551 is slidably inserted into the socket 522 and an abutment head 553 is provided at its outer end. Pressing the latch 551 can make it inserted into the corresponding fixing groove 532. A first spring 554 is connected between the abutment head 553 and the outer wall of the test seat 52 to provide an elastic force to move the latch 551 away from the fixing groove 532. The abutment plate 552 is fixedly installed on the front side of the substrate 4 and close to the side of the test seat 52 where the latch 551 is located. The upper end of the abutment plate 552 is curved outward in an arc shape. During specific use, when the telescopic cylinder 51 drives the test seat 52 to move downward and close to the notebook foot pad, the pin 551 can be moved downward synchronously and gradually approach the inner side of the upper end of the abutment plate 552. As the test seat 52 continues to move downward, the pin 551 will be pushed into the socket 522 along the arc trajectory of the abutment plate 552, so that the pin 551 is inserted into the fixed groove 532 to achieve the limited fixation of the turntable 53. When the test seat 52 moves upward, the pin 551 will move away from the fixed groove 532 under the action of the elastic force of the first spring 554, so as to facilitate the subsequent switching of the test head 531.

[0049] In order to prevent foreign matter such as impurities and particles from adhering to the surface of the test head 531 or the notebook foot pad and causing interference in the test process, such as Figure 2 and Figure 3 As shown, in one embodiment, a cleaning mechanism 6 is also included, which includes a rack 61, a transmission rod 62 and a cleaning rod 63. The rack 61 is longitudinally mounted on the test seat 52, and the transmission rod 62 is axially rotatably mounted on the front side of the substrate 4 and is laterally arranged. One end of the transmission rod 62 is provided with a second gear 621 meshing with the rack 61 and the other end of the transmission rod 62 is provided with a first bevel gear 622. The cleaning rod 63 is axially rotatably mounted on the front side of the substrate 4 and is longitudinally arranged. The top end of the cleaning rod 63 is provided with a second bevel gear 631 meshing with the first bevel gear 622. The bottom end of the cleaning rod 63 is laterally bent and located below the test seat 52, and is provided with bristles 632. When the telescopic cylinder 51 drives the test seat 52 to move down and close to the notebook pad, the rack 61 will move down synchronously and drive the transmission rod 62 to rotate through the second gear 621. The transmission rod 62 drives the cleaning rod 63 to rotate through the first bevel gear 622 and the second bevel gear 631, so that the laterally bent bottom end of the cleaning rod 63 can rotate in a circle with the cleaning rod 63 as the rotating axis, so that the bristles 632 can sweep the surface of the notebook pad and the end face of the test head 531, which is beneficial for cleaning the two in advance before the test head 531 contacts the notebook pad.

[0050] like Figure 6As shown, preferably, a pressure plate 555 is provided at one side of the bottom end of the abutment plate 552 close to the test seat 52, the pressure plate 555 is located below the test seat 52 and an airbag structure is provided on the top thereof, the cleaning rod 63 is a hollow tubular structure, and a plurality of air outlet holes 633 are provided on the side wall of the brush 632 portion, a ventilation hose 634 is connected between the airbag structure and the top end of the cleaning rod 63, when the test seat 52 moves downward, the airbag structure can be pressed to push the gas into the cleaning rod 63 through the ventilation hose 634 and spray it out from the air outlet holes 633, so that the bristles 632 generate wind force when sweeping over the surface of the notebook foot pad and the test head 531, and the attached objects are blown away, thereby further improving the cleaning effect on the surface of the notebook foot pad and the test head 531.

[0051] like Figure 5 As shown, specifically, the airbag structure includes a bottom shell 556, a bellows bag 557 and a pressing piece 558. The pressing piece 558 and the bottom shell 556 are respectively connected to the upper and lower ends of the bellows bag 557. The bottom shell 556 is installed on the pressure plate 555 and is connected to the ventilation hose 634. A second spring 559 is connected between the pressing piece 558 and the bottom shell 556. When the test seat 52 moves downward, it can push the pressing piece 558 downward, thereby compressing the bellows bag 557 to push the gas. When the test seat 52 moves upward, the pressing piece 558 will bounce upward under the elastic force of the second spring 559, so that the bellows bag 557 is reset.

[0052] Preferably, a plurality of air outlet holes 633 are respectively provided on the upper and lower sides of the side wall of the bristle 632 portion of the cleaning rod 63 to concentrate the wind force on the upper and lower sides of the bristle 632 to blow the wind force to the surface of the notebook foot pad and the test head 531 respectively.

[0053] When the present invention is used in practice, a test head 531 of corresponding material is selected as needed, and the test head 531 is directed to the bottom of the test seat 52 through the switching component 54, and then the test seat 52 is driven downward by the telescopic cylinder 51 to make the test head 531 close to the notebook foot pad. In the process of the test seat 52 moving downward, the turntable 53 is locked by the locking component 55 to prevent the turntable 53 from deflecting when the test head 531 tests the foot pad. At the same time, the cleaning mechanism 6 is also started synchronously to clean the test head 531 and the notebook foot pad in advance before the test head 531 contacts the notebook foot pad. The downward movement of the test seat 52 can also squeeze the airbag structure to spray gas from the air outlet 633 at the bristle 632, further improving the cleaning effect on the surface of the notebook foot pad and the test head 531, and preventing foreign matter from interfering with the notebook foot pad during testing.

[0054] The present invention combines the locking assembly 55, the cleaning mechanism 6 and the downward movement process of the test seat 52 in a linked manner, thereby completing the fixation of the turntable 53 and the cleaning of the notebook pad and the surface of the test head 531 before the test head 531 performs a wear resistance test on the notebook pad, eliminating interference from foreign matter, improving the accuracy of the test results, and improving the detection efficiency.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
