DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0026] like Figures 1 to 6 As shown, the embodiment of the present application provides a touch test assembly 1, which includes a bracket 11 and a plurality of conductive pen tip assemblies 18. The bracket 11 has at least one opening 17 extending through the first direction X, and the conductive pen tip assembly 18 includes a guide shaft 12, a conductive pen tip 13 and an elastic member 14. The guide shaft 12 is inserted into the opening 17 corresponding to the guide shaft 12 along the first direction X, and the guide shaft 12 has a cap 121, and the guide shaft 12 is hung on the bracket 11 through the cap 121; all the conductive pen tips 13 are electrically connected to each other, and the conductive pen tips 13 are arranged at one end of the guide shaft 12 away from the opening 17, and the conductive pen tips 13 can move relative to the bracket 11 along the first direction X; the two ends of the elastic member 14 press the conductive pen tip 13 and the bracket 11 respectively, and the elastic member 14 can be deformed in the first direction X. The first direction X can be the height direction of the bracket 11.
[0027] The two ends of the elastic member 14 respectively press the bracket 11 and the conductive pen tip 13. The elastic member 14 is compressed and contracted in the first direction X, so that the conductive pen tip 13 can adaptively adjust the height in the first direction X, ensuring that even if the surface to be detected is a non-horizontal surface, each conductive pen tip 13 can contact the surface to be detected under the elastic force of the elastic member 14.
[0028] The touch test component 1 can detect the capacitive touch screen, and its conductive pen tips 13 are electrically connected to each other. The bracket 11, the guide shaft 12 and the conductive pen tip 13 of the touch test component 1 can all be made of conductive materials, so that the touch test component as a whole becomes a conductor. The bracket 11 provides a connection carrier so that the guide shaft 12 and the conductive pen tip 13 can be installed on the bracket 11. The guide shaft 12 and the conductive pen tip 13 can be detachably connected by screwing, clamping or plugging, so that when the conductive pen tip 13 is worn, the conductive pen tip 13 can be replaced.
[0029] The elastic member 14 is disposed between the conductive pen tip 13 and the bracket 11 and can be deformed in the first direction X. When the detection is performed, the touch screen presses the conductive pen tip 13, and the elastic member 14 can provide a reaction force to ensure that the conductive pen tip 13 can always contact the touch screen. The elastic member 14 can be a structure that can produce deformation, such as a spring, an elastic sleeve or a gasket. In a specific structure, the elastic member 14 can be a spring, and the spring is sleeved on the guide shaft 12, and the two ends of the spring respectively abut the bracket 11 and the conductive pen tip 13; in an alternative structure, multiple springs surround the guide shaft 12, and the two ends of each spring respectively press the conductive pen tip 13 and the bracket 11, and each spring can be symmetrically arranged about the guide shaft 12. In another specific structure, the elastic member 14 is an elastic sleeve, and the elastic sleeve is sleeved on the guide shaft 12, and the two ends of the elastic sleeve respectively abut the bracket 11 and the conductive pen tip 13. In another specific structure, the elastic member 14 is an elastic gasket, which is arranged outside the guide shaft and abuts against the bracket 11 and the conductive pen tip 13 .
[0030] For the touch test component, there are mainly two ways in which the conductive pen tip 13 can move relative to the bracket 11 along the first direction X. One is that the guide shaft 12 and the conductive pen tip 13 move together relative to the bracket 11, and the other is that the guide shaft 12 is fixed to the bracket 11 and the conductive pen tip 13 can move relative to the guide shaft 12 and the bracket 11.
[0031] In some embodiments, the guide shaft 12 moves with the conductive pen tip 13 relative to the bracket 11 along the first direction X. The conductive pen tip assembly 18 also includes a sleeve 16, which penetrates up and down along the first direction X, and is inserted and fixed in the opening 17 corresponding thereto. The guide shaft 12 is inserted in the sleeve 16 corresponding thereto, and the two ends of the elastic member 14 are respectively in contact with the bracket 11 and the conductive pen tip 13, and can move along the first direction X. The conductive pen tip 13 can move upward along the first direction X with the guide shaft 12, and during this process, the elastic member 14 can be compressed; the conductive pen tip 13 can also move downward along the first direction X with the guide shaft 12, and during this process, the elastic member 14 can stretch.
[0032] The sleeve 16 has a flange 161 protruding in a second direction Y that is angled with the first direction X. The flange 161 can buckle the lower end surface of the bracket 11, and one end of the elastic member 14 can indirectly abut against the bracket 11 by abutting against the flange 161. The second direction Y is perpendicular to the first direction X, and the second direction Y can be the length direction of the bracket 11.
[0033] The overall shape of the sleeve 16 can be an inverted T-shape, an L-shape, etc. The flange 161 can be integrally formed with the sleeve 16, or the flange 161 can be independently provided with the sleeve 16 and fixed to the bottom of the sleeve 16 by means of clamping, welding or bonding. In an alternative structure, the sleeve 16 can also be provided without the flange 161. The sleeve 16 is fixed in the opening 17 corresponding thereto, and one end of the elastic member 14 can directly abut the lower end surface of the bracket 11.
[0034] The conductive pen tip assembly 18 also includes a fixing member 15, which is connected to the sleeve 16 and can fix the sleeve 16 to the bracket 11. The fixing member 15 is exemplified as a nut, and a threaded section is provided on the top of the sleeve 16. The fixing member 15 is threadedly connected to the threaded section and tightly presses the upper end surface of the bracket 11. By providing the flange 161 and the fixing member 15, the sleeve 16 can be fixed to the bracket 11 and cannot move along the first direction X and the second direction Y.
[0035] The guide shaft 12 has a cap 121 at the top in the first direction X. In a normal state, the cap 121 can press against the fixing member 15 to prevent the guide shaft 12 from sliding off the bracket 11 .
[0036] When the touch screen is detected, the conductive pen tip 13 and the guide shaft 12 can move up and down relative to the bracket 11 in the first direction X, and the elastic force provided by the elastic member 14 enables the conductive pen tip 13 to press against the capacitive touch screen.
[0037] In this embodiment, the conductive tip 13 is made of conductive rubber, conductive blanket or other elastic conductive material, and the conductive tip 13 can be deformed and pressed against the touch screen when subjected to force. Since the conductive tip 13 is electrically conductive, the bracket 11, the guide shaft 12, the fixing member 15 and the sleeve 16 can all be made of conductive materials.
[0038] In some embodiments, the guide shaft 12 can be fixed and the conductive pen tip 13 can move relative to the guide shaft 12 along the first direction X. Figure 2As shown, the conductive pen tip assembly 18 does not include the sleeve 16, and a cap 121 is provided at the top of the guide shaft 12 near the bracket 11, and the cap 121 fixes the guide shaft 12 to the bracket 11. The cap 121 is exemplified by a nut, and a threaded section is correspondingly provided at the top of the guide shaft 12. The nut cooperates with the threaded section and the nut presses the upper end surface of the bracket 11, so that the guide shaft 12 cannot move relative to the bracket 11 along the first direction X and the second direction Y. The conductive pen tip 13 is hollow inside and has a receiving space 131. The bottom of the guide shaft 12 is inserted into the receiving space 131 along the first direction X and is slidably connected to the conductive pen tip 13. The two ends of the elastic member 14 press the bracket 11 and the conductive pen tip 13 respectively.
[0039] Furthermore, the guide shaft 12 may be provided with a protrusion 122 protruding in the second direction Y, the protrusion 122 abuts against the lower end surface of the bracket 11 , and one end of the elastic member 14 abuts against the protrusion 122 to achieve indirect abutment with the bracket 11 .
[0040] When the conductive pen tip 13 detects the capacitive touch screen, the conductive pen tip 13 can move up and down in the first direction X relative to the guide shaft 12, and the elastic force provided by the elastic member 14 enables the conductive pen tip 13 to press against the capacitive touch screen.
[0041] When there are multiple groups of conductive pen tip assemblies 18, all of the conductive pen tip assemblies 18 may include the sleeve 16 so that the guide shaft 12 can move up and down relative to the bracket 11, or all of the conductive pen tip assemblies 18 may not include the sleeve 16 so that the guide shaft 12 and the bracket 11 are fixed, or some of the conductive pen tip assemblies 18 may include the sleeve 16 while the remaining conductive pen tip assemblies 18 do not include the sleeve 16.
[0042] For the touch test component, the conductive pen tip assembly 18 can be fixed relative to the bracket 11 in the second direction Y; the conductive pen tip assembly 18 can also be moved along the second direction Y on the bracket 11 to adjust the spacing of the conductive pen tips 13 to meet the requirements of different touch screen test schemes for the spacing of the conductive pen tips 13.
[0043] In some embodiments, the conductive pen tip assembly 18 can move on the bracket 11 along the second direction Y. There can be only one opening 17 on the bracket 11, and the opening 17 is a long strip opening 17 extending along the second direction Y. All conductive pen tip assemblies 18 are inserted into the opening 17 and can move along the second direction Y.
[0044] Since the conductive pen tip assembly 18 can move along the second direction Y on the bracket 11, the position of each conductive pen tip 13 and the spacing between the conductive pen tips 13 can be accurately adjusted, so that one touch test assembly 1 can complete the test requirements of various spacing specifications, reducing the number of test tools and further reducing tooling investment.
[0045] When the guide shaft 12 of the conductive pen tip assembly 18 can move in the first direction X, the conductive pen tip assembly 18 can include a sleeve 16, and the guide shaft 12 can be installed on the bracket 11 through the sleeve 16, and the sleeve 16 is fixed to the bracket 11 by the fixing member 15. When it is necessary to adjust the spacing of the conductive pen tip 13, the fixing member 15 is loosened, and the conductive pen tip assembly 18 can be moved left and right along the second direction Y on the bracket 11; after the adjustment is in place, the fixing member 15 is tightened to fix the conductive pen tip assembly 18 to the bracket 11.
[0046] When the guide shaft 12 of the conductive pen tip assembly 18 is fixed to the bracket 11, the conductive pen tip assembly 18 may not include the sleeve 16, and the guide shaft 12 is fixed to the bracket 11 through the cap 121, and the cap 121 may be a nut, and a threaded section is correspondingly provided on the top of the guide shaft 12. When the spacing of the conductive pen tip 13 needs to be adjusted, the conductive pen tip assembly 18 can be moved along the second direction Y by loosening the nut; after the adjustment is in place, the conductive pen tip assembly 8 is fixed to the bracket 11 by tightening the nut.
[0047] In order to achieve precise adjustment of the position of the conductive pen tip 13 , the bracket 11 is further provided with a scale 19 extending along the second direction Y, and the scale of the scale 19 corresponds to the moving distance of the conductive pen tip 13 .
[0048] like Figure 3 As shown, the bracket 11 has a long strip opening 17 that passes through along the first direction X, and the opening 17 extends along the second direction Y. A scale 19 is provided on the bracket 11 corresponding to the opening 17. After loosening the nut, the sleeve 16 can be moved along the second direction Y, and then the accurate position of the conductive pen tip 13 is determined by the scale 19. After moving into place, tighten the screw to fix it.
[0049] When there are multiple rows of openings 17, correspondingly, there are multiple rows of conductive pen tip assemblies 18. Each row includes a long strip opening 17, and each row of conductive pen tip assemblies 18 corresponds to an opening 19. For each row of conductive pen tip assemblies 18, the guide shafts 12 of each conductive pen tip assembly 18 can be installed on the bracket 11 through the sleeve 16; the guide shafts 12 of each conductive pen tip assembly 18 can be fixed to the bracket 11; or part of the guide shaft 12 is installed on the bracket 11 through the sleeve 16 and the remaining part of the guide shaft 12 is fixed to the bracket 11.
[0050] In some embodiments, the conductive pen tip assembly 18 can be fixed relative to the bracket 11 in the second direction Y.
[0051] like Figure 4 As shown, there are a plurality of openings 17 on the bracket 11 that are spaced apart in the second direction Y, and the openings 17 correspond one-to-one to the conductive pen tip assemblies 18 .
[0052] The guide shaft 12 of each conductive pen tip assembly 18 can be installed on the bracket 11 through the sleeve 16, and the sleeve 16 is fixed to the bracket 11 through the fixing member 15; or the guide shaft 12 can be directly fixed to the bracket 11, and the guide shaft 12 is fixed by the cap 121, and the cap 121 is a nut; with this structure, each conductive pen tip assembly 18 cannot move along the second direction Y.
[0053] When there are multiple rows of openings 17, correspondingly, there are multiple rows of conductive pen tip assemblies 18. Each row includes multiple openings 17 distributed at intervals. Figure 5 As shown, there are two rows of openings 17 on the bracket 11 , each row has four openings 17 , and each opening 17 corresponds to a conductive pen tip assembly 18 .
[0054] In some embodiments, part of the conductive pen tip assembly 18 can move along the second direction Y, and part of the conductive pen tip assembly 18 is fixed and cannot move along the second direction Y.
[0055] Specifically, each row of openings 17 includes at least a plurality of openings 17. Figure 6 As shown, a row may have multiple openings 17, some of the openings 17 in each row are long strip openings and can correspond to multiple conductive pen tip assemblies 18, and some of the openings 17 correspond to one conductive pen tip assembly 18. When there are multiple rows of openings 17, each row may include one or more openings.
[0056] In the second aspect, the embodiment of the present application provides an application of a touch test component 1 on a test touch screen. The touch screen may be a capacitive touch screen, an optical touch screen, or an infrared touch screen. By moving the bracket 11, the conductive pen head 13 can perform a multi-point line drawing test or a click test on the touch screen. In a specific embodiment, the touch screen may be an infrared touch screen, which has a horizontally and vertically crossed infrared matrix. The touch point is determined by the coordinates of the infrared rays blocked by all the conductive pen heads 13 on the touch screen, so a click test or a line drawing test can be performed. In another specific embodiment, the touch screen is a capacitive touch screen, so the touch screen has a TX electrode and an RX electrode. When no one touches it, a stable electric field is formed between the TX electrode and the RX electrode. When a finger touches the surface of the capacitive screen, the electric field between TX and RX will be changed. The touch control algorithm determines whether there is a touch and calculates the coordinate point by comparing the difference before and after the touch. Therefore, the detection personnel hold the conductive pen head 13 so that the mutual capacitance on the capacitive screen is transmitted to the ground through the human body, and the click test or the line drawing test is performed by the change of the mutual capacitance on the touch screen.
[0057] When performing a capacitive touch test, a person holds the bracket 11 and makes the conductive pen tip 13 touch the capacitive touch screen, so that the stable electric field between the capacitive screen TX and RX is transmitted to the human body through the bracket 11, so that the stable electric field between TX\RX is changed and can change to form a reporting point, which can effectively simulate the simultaneous touch of human fingers.
