Description

Technical Field

[0002] As automotive intelligence continues to rise, the performance and reliability of in-vehicle touchscreens, a core component of human-machine interaction, directly impact the user experience. Modern in-vehicle touchscreens typically utilize capacitive or resistive touch technology, achieving precise touch positioning through a multi-layer composite film structure. These screens must withstand challenging operating conditions such as extreme temperatures, humidity, vibration, and long-term mechanical wear.

[0003] Reliability testing methods currently commonly used in the industry include mechanical durability testing, environmental adaptability testing, and electromagnetic compatibility testing to simulate touch operations in a laboratory environment. During testing, the touchscreen is typically placed horizontally on a test platform, and automated equipment is used to simulate touch operations of varying force and frequency. However, this testing method differs significantly from the actual installation angle of the touchscreen in the vehicle. This is particularly true in vehicles with tilted center consoles, where the operating angle of the touch panel changes the force distribution and contact area of ​​the user's fingers during operation. Currently, there are no mature testing tools capable of performing simulation tests at these operating angles.

[0031] like Figure 1-Figure 7 As shown, the present invention provides a touch detection device for a display screen, including a frame 1, an angle adjustment mechanism 2 and a touch clicking mechanism; the angle adjustment mechanism 2 includes a positioning frame 201, a screen clamp 202 and a driving component, the screen clamp 202 is set on the positioning frame 201, and is used to position the screen. One end of the positioning frame 201 is rotatably connected to the frame 1, and the driving component drives the other end of the positioning frame 201 to move, so that the positioning frame 201 rotates relative to the frame 1; the touch clicking mechanism includes a clicking component 4 and a position adjustment component 3, the position adjustment component 3 is connected to the positioning frame 201, the clicking component 4 is connected to the position adjustment component 3, the clicking component 4 includes a contact 406 and a driving component 401, and the driving component 401 can drive the contact 406 to move in a direction close to or away from the screen.

[0032] Compared with the existing technology, the display screen touch detection device provided by this application has the following advantages: The display screen touch detection device provided in the present application can provide an installation basis for the angle adjustment mechanism 2 through the frame 1, and the angle adjustment mechanism 2 in the present application includes a positioning frame 201, a screen clamp 202 and a driving component. The positioning frame 201 can provide an installation basis for the screen clamp 202, and the screen clamp 202 can clamp and position the screen 5 to be tested. It can be understood that since one end of the positioning frame 201 in the present application is rotatably connected to the frame 1, and the other end is the adjustment end, the adjustment end can be driven to move by the driving component, so that the positioning frame 201 can rotate with the position of rotational connection with the frame 1 as the center of the circle, thereby realizing the angle adjustment of the screen positioned on the screen clamp 202.

[0033] Accordingly, since the positioning frame 201 in the present application is also connected to a touch-clicking mechanism, and the touch-clicking mechanism in the present application includes a clicking component 4 and a position adjustment component 3, the position adjustment component 3 is connected to the positioning frame 201, and the clicking component 4 is connected to the position adjustment component 3. Therefore, the position adjustment component 3 can be used to adjust the position of the clicking component 4. After the position is adjusted to the right position, the driving component 401 can be used to move the contact 406 toward or away from the screen 5 to be tested, thereby enabling the screen to be touch tested at the required angle.

[0034] It should be noted here that the driving component in the angle adjustment mechanism 2 in the present application can adopt an electric telescopic rod of an air cylinder, an oil cylinder or other structure, such as using a motor to drive the screw to rotate, and the screw nut is connected to the screw. At the same time, the screw nut is connected to a push rod, and the end of the push rod away from the screw nut is rotatably connected to the positioning frame 201, so that the positioning frame 201 can be adjusted within a certain angle range relative to the frame 1 through the movement of the screw nut on the screw, thereby realizing the touch test of the simulated screen in the vehicle-mounted installation state.

[0035] Furthermore, the above-mentioned driving component 401 in the present application can also adopt a cylinder, an oil cylinder or a structure consistent with the above-mentioned motor-driven screw rod and the screw nut, except that the screw nut is connected to the above-mentioned contact 406, so as to achieve reciprocating motion in a straight line.

[0036] The above-mentioned position adjustment component 3 can directly adopt the existing mechanical arm structure, and use the gripper set at the front end of the mechanical arm to clamp the click component 4. At the same time, the flexible adjustment of the mechanical arm can be used to realize touch detection actions at various positions of the screen 5 to be tested.

[0037] It needs to be further explained here that the rotational connection between the positioning frame 201 and the frame 1 in the present application can be achieved by using a structure such as a rotating shaft or a pin shaft 1071. For example, the rotating shaft is fixedly connected to the frame 1, and a bearing can be set at the position of the rotating shaft corresponding to the positioning frame 201. The bearing can be used to achieve the rotational connection between the positioning frame 201 and the rotating shaft, thereby achieving the rotational connection of the positioning frame 201 relative to the frame 1.

[0038] Alternatively, as Figure 1-Figure 7 As shown, the frame 1 in the present application includes a main frame, an adjustment plate and a positioning beam 106. The positioning beam 106 extends along the first direction S1 and is fixed to the bottom frame of the main frame. The two ends of the adjustment plate are respectively connected to the two columns of the main frame in the second direction S2, and are arranged close to the top frame of the main frame. The adjustment plate includes an arc segment, and a rack 105 is formed on the arc segment; the driving assembly is arranged at a position of the positioning frame 201 corresponding to the rack 105, and the driving assembly includes a driving wheel 204 and a first hand wheel 203; a base 107 is provided on the positioning beam 106, and a rotating part is provided at the bottom of the positioning frame 201 corresponding to the position of the base 107, the rotating part is rotatably connected to the base 107, the driving wheel 204 is rotatably connected to the position of the positioning frame 201 corresponding to the adjustment plate, the first hand wheel 203 is connected to the driving wheel 204, and is coaxially arranged, and the driving wheel 204 is meshed with the rack 105.

[0039] The frame 1 in the present application is a rectangular frame 1, which is formed by four columns and eight beams. Among them, four beams constitute the bottom frame, four beams constitute the top frame, and four columns are correspondingly arranged between the top frame and the bottom frame to form the above-mentioned rectangular frame 1, which provides an installation and support basis for the structure provided by the present application.

[0040] Since the positioning frame 201 in the present application needs to be rotatably connected to the frame 1, the present application further sets a positioning beam 106, and extends the positioning beam 106 along the first direction S1 and is connected to the bottom frame, so as to provide a mounting frame foundation for the base 107, and the base 107 set on the positioning beam 106 can realize the rotational connection between the positioning frame 201 and the frame 1.

[0041] In actual application, the base 107 in this application is composed of a base body and a pin shaft 1071. The base body is U-shaped and has positioning holes formed at both ends. The pin shaft 1071 can be set through the positioning holes. Accordingly, a rotating part is formed at the position of the positioning frame 201 corresponding to the base 107, and the rotating part can be a block structure and have a connecting hole that passes through the rotating part axially. Therefore, during assembly, the rotating part is embedded in the base 107, and the connecting hole is aligned with the positioning hole. After that, the pin shaft 1071 is rotated to realize the rotation of the rotating part relative to the base 107, and then the positioning frame 201 is rotated relative to the frame 1.

[0042] In the present application, at least two bases 107 are provided on the positioning beam 106 , and the two bases 107 are preferably located at both ends of the positioning beam 106 to ensure the stability of the rotational connection and the stability of the rotation process.

[0043] Based on the above structure, the present application provides a method for achieving stable rotation of the positioning frame 201, wherein the driving assembly includes a driving wheel 204 and a first hand wheel 203, and the driving wheel 204 in the present application is a gear. Accordingly, the arc section of the adjustment plate is formed with a rack 105, so that through the engagement of the gear and the rack 105, the stability of the rotation process of the positioning frame 201 can be guaranteed to a certain extent, and after being in place, the position stability between the positioning frame 201 and the frame 1 can be achieved through the engagement between the meshing teeth.

[0044] It can be understood that the present application connects the first hand wheel 203 coaxially with the driving wheel 204. When the positioning frame 201 needs to be rotated, the first hand wheel 203 is rotated to drive the gear to rotate, thereby moving on the rack 105, and then driving the positioning frame 201 to rotate relative to the frame 1.

[0045] Preferably, an angle scale 104 is also formed on the arc segment in the present application. Accordingly, an arc-shaped hollow hole 108 that is adapted to the arc is formed at the position of the adjustment plate corresponding to the arc segment. An angle pointer is provided on the positioning frame 201, and the angle pointer is connected to the positioning frame 201 through a connecting rod. The connecting rod passes through the arc-shaped hollow hole so that the pointer is set corresponding to the angle scale 104, so that the angle pointer can be used to reflect the deflection angle of the positioning frame 201, and then the deflection angle of the screen to be tested 5 can be accurately located, so that the screen to be tested 5 is closer to or consistent with the actual angle after installation.

[0046] Optionally, the display screen touch detection device provided in the present application further includes a first locking mechanism, which includes a first locking component 101, a second locking component 102 and a third locking component 103; the first locking component 101 and the second locking component 102 are relatively arranged at both ends of the positioning beam 106 and are connected to the bottom frame; the third locking component 103 extends along the second direction S2 and is located above the second locking component 102; the first locking component 101, the second locking component 102 and the third locking assembly 103 include a locking plate 1011, a locking handle 1012 and a threaded portion 1013. The locking plate 1011 is connected to the frame 1 and extends in the vertical direction. An arc-shaped guide hole is formed on the locking plate 1011, and a locking hole is formed on the positioning frame 201. One end of the threaded portion 1013 passes through the arc-shaped guide hole and is connected to the locking hole. The locking handle 1012 is connected to the other end of the threaded portion 1013, and the locking handle 1012 can abut against the locking plate 1011.

[0047] In order to ensure that the position of the positioning frame 201 is fixed after adjustment, the present application sets a first locking component 101, a second locking component 102 and a third locking component 103, which can achieve locking of the positioning frame 201 after position adjustment, thereby avoiding the problem of angle changes of the positioning frame 201 during the touch and click process, resulting in inaccurate test results.

[0048] It can be understood that the locking hole formed on the positioning frame 201 in the present application is a screw hole, and the locking handle 1012 is connected to a side of the locking plate 1011 with an abutment nut, and the diameter of the abutment nut is larger than the diameter of the arc-shaped guide hole, so that the abutment nut can abut against the locking plate 1011.

[0049] During actual operation, the threaded portion 1013 is always inserted into the locking hole, and during the adjustment of the positioning frame 201, the threaded portion 1013 moves along the arc-shaped guide hole. After the angle adjustment is completed, the locking handle 1012 is rotated to enable the threaded portion 1013 to be screwed into the locking hole. As the threaded portion 1013 goes deeper, the abutment nut can get closer and closer to the locking plate 1011 until it abuts against the locking plate 1011, thereby locking the positioning frame 201.

[0050] In this application, the first locking assembly 101, the second locking assembly 102 and the third locking assembly 103 all use this method to achieve locking, which will not be repeated here.

[0051] Alternatively, as Figure 1-Figure 7 As shown, the position adjustment component 3 in this application includes a horizontal adjustment component 301 and a vertical adjustment component 302; the horizontal adjustment component 301 includes a first connecting seat 3012, a first mounting seat 3013, a second hand wheel 3014, a first screw rod 3011 and a first matching nut 3015; the first connecting seat 3012 is fixedly connected to the positioning frame 201, and the first connecting seat 3012 is formed with a first connecting end and a second connecting end, one end of the first screw rod 3011 passes through the first connecting end and is connected to the second hand wheel 3014, and the other end of the first screw rod 3011 is rotatably connected to the second connecting end; the first matching nut 3015 is arranged on the first screw rod 3011, and the first mounting seat 3013 is connected to the first matching nut 3015; the vertical adjustment component 302 is arranged on the first mounting seat 3013 along the vertical direction, and the click component 4 is connected to the vertical adjustment component 302.

[0052] By forming the first connecting end and the second connecting end of the first connecting seat 3012, a mounting base can be provided for the first screw rod 3011. Accordingly, a receiving hole is formed on the first connecting end and the second connecting end, and a bearing is provided in the receiving hole. The two ends of the first screw rod 3011 are respectively connected to the inner ring of the bearing, so that the first screw rod 3011 can be rotated relative to the first connecting seat 3012.

[0053] It is understandable that one end of the first screw rod 3011 is connected to the second hand wheel 3014, so that the first screw rod 3011 can be controlled by the second hand wheel 3014. Since the first screw rod 3011 is further provided with a matching first mating nut 3015, when the first screw rod 3011 rotates, the first mating nut 3015 can move on the first screw rod 3011. Since the first mounting seat 3013 is connected to the first mating nut 3015 in the present application, the movement of the first mating nut 3015 on the first screw rod 3011 can drive the movement of the first mounting seat 3013, thereby driving the vertical adjustment assembly 302 provided on the first mounting seat 3013 to move in the horizontal direction.

[0054] Since the click component 4 in the present application is arranged on the vertical adjustment component 302, the movement of the vertical adjustment component 302 on the first screw rod 3011 can synchronously drive the click component 4 to move, thereby changing the position of the contact 406 in the horizontal direction.

[0055] Alternatively, as Figure 1-Figure 7 As shown, there are multiple vertical adjustment components 302 in this application, the number of first screw rods 3011 corresponds to the number of vertical adjustment components 302, and the first mating nut 3015, the first mounting seat 3013 and the second hand wheel 3014 all correspond to the number of first screw rods 3011.

[0056] Preferably, the number of vertical adjustment components 302 in the present application is three, and accordingly, there are three first screw rods 3011, which are located at the same level and arranged parallel to each other. Accordingly, in order to achieve that the actions of the three vertical adjustment components 302 do not interfere with each other, a first mating nut 3015 is provided on a first screw rod 3011 in the present application, and the first mating nut 3015 is connected to a first mounting seat 3013, and a vertical adjustment component 302 is installed on the first mounting seat 3013. Of course, the second hand wheel 3014 corresponds one-to-one to the first screw rod 3011, so that the adjustment of the three first screw rods 3011 can be carried out simultaneously or independently without affecting each other.

[0057] It is understandable that, since the vertical components can be designed to be multiple, the number of click components 4 can also match the vertical components, so that multiple touches can be performed simultaneously, thereby improving work efficiency.

[0058] It should be additionally explained here that, in the present application, the first screw rod 3011 extends along the first direction S1, so that the position of the vertical adjustment component 302 can be adjusted in the first direction S1.

[0059] Alternatively, as Figure 1-Figure 7As shown, the vertical adjustment component 302 in the present application includes a second connecting seat 3022, a second mounting seat 3023, a third hand wheel 3024, a second screw rod 3021 and a second mating nut 3025; the second connecting seat 3022 is formed with a third connecting end and a fourth connecting end, the fourth connecting end is fixedly connected to the first mounting seat 3013, one end of the second screw rod 3021 passes through the third connecting end and is connected to the third hand wheel 3024, and the other end of the second screw rod 3021 is rotatably connected to the fourth connecting end; the second mating nut 3025 is arranged on the second screw rod 3021, and the second mounting seat 3023 is connected to the second mating nut 3025, and the click component 4 is connected to the second mounting seat 3023.

[0060] The second connecting base 3022 in the present application can provide a mounting base for the second screw rod 3021. Accordingly, the second screw rod 3021 is also rotatably connected to the second connecting base 3022 via a bearing. By connecting the third hand wheel 3024 to one end of the second screw rod 3021 passing through the third connecting end, the third hand wheel 3024 can be used to control the second screw rod 3021 when adjustment is required.

[0061] It can be understood that since the second mating nut 3025 is arranged on the second screw rod 3021, when the second screw rod 3021 rotates, the second mating nut 3025 can realize reciprocating motion on the second screw rod 3021, and since the second mounting seat 3023 is connected to the second mating nut 3025, the click component 4 is connected to the second mounting seat 3023, therefore, the movement of the second mounting seat 3023 can drive the click component 4 to move, thereby realizing the position adjustment of the click component 4 in the vertical direction.

[0062] Preferably, the vertical adjustment assembly 302 in the present application also includes a first guide column 3030 and a first slider 3028, the first guide column 3030 is supported on the third connection end and the fourth connection end of the second connection seat 3022, the second mounting seat 3023 is formed with a first through-hole, and the first guide column 3030 is set through the first through-hole; the third connection end and the fourth connection end of the second connection seat 3022 are both provided with a first slider 3028, and the positioning frame 201 is formed with a slide rail 205 at the position corresponding to the third connection end and the fourth connection end of the second connection seat 3022, and the first slider 3028 slides in cooperation with the slide rail 205.

[0063] By setting a first guide column 3030 between the third connection end and the fourth connection end, and forming a first perforation corresponding to the second mounting seat 3023, the first guide column 3030 can make the movement of the second mounting seat 3023 in the vertical direction more stable, thereby ensuring the stability of the click component 4 in the vertical direction.

[0064] Accordingly, by forming a slide rail 205 on the positioning frame 201 and setting a first slider 3028 on the second connecting seat 3022, the connection stability of the third connecting end and the fourth connecting end of the second connecting seat 3022 can be achieved through the cooperation between the first slider 3028 and the slide rail 205, thereby ensuring the stability of the overall vertical adjustment component 302 during the horizontal movement process.

[0065] It should be noted here that in the present application, the slide rail 205 extends along the first direction S1, and a horizontal scale 206 extending along the first direction S1 is also provided near the position of the positioning frame 201 corresponding to the slide rail 205. Accordingly, a horizontal pointer 3017 can be connected to the first slider 3028, so that the pointing position of the horizontal pointer 3017 on the horizontal scale 206 can reflect the horizontal position of the vertical adjustment component 302, thereby ensuring the position adjustment accuracy.

[0066] It needs to be further explained here that in the present application, a vertical scale column 3029 can be further set between the third connection end and the fourth connection end of the second connecting seat 3022, and a vertical scale 3029 is formed on the vertical scale column 3029 along the vertical direction. Accordingly, a vertical pointer 3027 can be further installed on the second mounting seat 3023. The pointing position of the vertical pointer 3027 on the vertical scale 3029 reflects the position of the click component 4 in the vertical direction, thereby ensuring the accuracy of position adjustment.

[0067] Preferably, in this application, a horizontal locking assembly 3016 is connected to the first connecting seat 3012, and a vertical locking assembly 3026 is connected to the second connecting seat 3022, and both the horizontal locking assembly 3016 and the vertical locking assembly 3026 include an operating handle and a threaded rod. Taking the horizontal locking assembly 3016 as an example, a locking through-hole is formed on the first connecting seat 3012, and the locking through-hole is a threaded hole. The threaded rod is arranged to pass through the locking through-hole, and the threaded rod is driven to rotate by the operating handle to move the end of the threaded rod toward or away from the first screw rod 3011. When the end of the threaded rod abuts against the first screw rod 3011, the first screw rod 3011 can be locked.

[0068] It can be understood that the structure and operation process of the vertical locking assembly 3026 in this application are consistent with those of the horizontal locking assembly 3016, and the number can be set according to the specific design number of the first screw rod 3011 and the second screw rod 3021, which will not be repeated here.

[0069] Alternatively, as Figure 1-Figure 7As shown, the click component 4 in the present application also includes a third screw rod 403, a third mating nut 407 and a third connecting seat 404; the output end of the driving member 401 is connected to the third screw rod 403, the third mating nut 407 is matingly connected to the third screw rod 403, the third connecting seat 404 is connected to the third mating nut 407, and the contact 406 is connected to the third connecting seat 404.

[0070] The driving component 401 in this application is a high-temperature resistant motor. The driving component 401 is installed on the second mounting seat 3023 so that it can move synchronously with the second mounting seat 3023. The output end of the driving component 401 is connected to the third screw rod 403 through the coupling 402, so that the third screw rod 403 can be automatically rotated.

[0071] Accordingly, the third screw rod 403 is provided with a third mating nut 407, so that when the third screw rod 403 rotates, the third mating nut 407 can reciprocate along the third screw rod 403. Since the third connecting base 404 in the present application is connected to the third mating nut 407, it can move synchronously with the third mating nut 407. Since the contact 406 is connected to the third connecting base 404, the reciprocating motion of the contact 406 can be achieved.

[0072] Preferably, the click component 4 in the present application also includes a second guide column 405, which is arranged parallel to the third screw rod 403, and the second guide column 405 is connected to the second mounting seat 3023. The third connecting seat 404 is formed with a second through-hole at the position corresponding to the second guide column 405, and the second guide column 405 is arranged through the second through-hole.

[0073] By further setting up a second guide column 405 parallel to the third screw rod 403, it can play a guiding and limiting role when the third connecting seat 404 moves, thereby ensuring the stability of the movement process of the contact 406 and avoiding the problem of contact 406 shaking that affects the test accuracy.

[0074] Alternatively, as Figure 1-Figure 7 As shown, the click component 4 in the present application also includes a limit baffle 410, a pressure sensor 408 and an optical sensor 409; the pressure sensor 408 is connected to the contact 406, and the optical sensor 409 is arranged at one end of the second mounting seat 3023 away from the contact 406, and the limit baffle 410 includes a shielding part and a connecting rod part, one end of the connecting rod part is connected to the third connecting seat 404, and the other end is connected to the shielding part.

[0075] In this application, by connecting the contact 406 to the pressure sensor 408, the pressure applied by the contact 406 to the screen 5 to be tested can be monitored, thereby simulating the touch force in different application scenarios and ensuring that the tested screen can meet various scenarios in actual use.

[0076] The distance that the contact 406 moves can be controlled by the limit baffle 410. The optical sensor 409 in this application is a proximity switch. When the blocking portion completely blocks the proximity switch, the master control of the device can control the driving component 401 to stop. When the blocking portion completely leaves the detection area of ​​the proximity switch, the master control can also control the driving component 401 to stop. Of course, when the detection area of ​​the proximity switch is completely blocked or completely leaves the detection area of ​​the proximity switch, the rotation direction of the driving component 401 restarts.

[0077] It can be understood that since the optical sensor 409 in this application is set at the tail position of the click component 4, this application can extend the shielding part toward the tail by setting a connecting rod part on the third connecting seat 404, and set it corresponding to the optical sensor 409 to achieve the above-mentioned detection function.

[0078] It should be noted here that since the screen tested in this application is a vehicle-mounted screen, and the driving and parking environment of the vehicle may cause a high or low temperature environment in the cockpit, the screen 5 to be tested needs to simulate high and low temperature environments when testing. In this application, the vertical adjustment component 302 and the horizontal adjustment component 301 are both adjusted by the handwheel 203, eliminating a large number of motors, and the driving component 401 uses a high-temperature resistant motor. Therefore, it can reduce to a certain extent the problem that the driving components cannot adapt to high and low temperature environments during the simulation process, resulting in an increase in the failure rate of the overall device.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
