Description

Technical Field

[0001] This invention relates to the field of central control screen testing technology, and more specifically, to a vehicle central control screen testing device. Background Technology

[0002] With the rapid development of the automotive industry and the continuous improvement of vehicle intelligence, the central control screen has become a core component of the vehicle's human-machine interaction system. Among them, the touch screen sensor is a key component for realizing user interaction with the central control screen, and its performance directly affects the user experience as well as the convenience and safety of vehicle operation. Therefore, accurate and efficient detection of the touch screen sensor of the central control screen is of paramount importance.

[0003] There are many existing technologies for detection devices, such as:

[0004] Chinese Patent Publication No. CN116699195B discloses a vehicle central control screen testing device, including a main body mechanism with a sliding hanging mechanism on it; an adjusting mechanism rotating on the main body mechanism; a fixing mechanism connected to the adjusting mechanism; a driving mechanism rotating on the main body mechanism; and a clamping mechanism connected to the driving mechanism. The central control screen is placed in the middle of the clamping mechanism, and the clamping mechanism is activated to fix the central control screen during sliding. The driving mechanism is rotated to rotate the central control screen, facilitating the removal of the central control screen's back cover during testing. After the motherboard is removed from the central control screen, the fixing mechanism is activated to fix the motherboard. The adjusting mechanism can be rotated to adjust the placement angle of the motherboard during testing. The hanging mechanism is pulled out from the main body mechanism to facilitate the placement of tools used during testing. The main body mechanism can also store bolts removed from the back cover.

[0005] However, some problems still exist in actual use:

[0006] 1. In the traditional process of testing the central control screen, it is highly dependent on manual operation. Testers need to frequently and point by point on the control screen to test each function, such as screen response speed and touch sensitivity. The manual testing method greatly limits the testing efficiency. With the continuous expansion of automobile production scale, it is difficult to meet the needs of large-scale and high-efficiency production testing, which seriously restricts the overall progress of automobile manufacturing and increases production costs.

[0007] 2. In actual driving, drivers may interact with the central control screen under different environmental conditions. Current testing processes often only perform simple functional tests under normal conditions, ignoring the impact of these complex and varied actual usage scenarios on the touch screen performance. For example, when operating the central control screen, people often repeatedly click on the touch screen area. If such operations are not tested and identified, it can easily affect the accuracy of the central control screen test.

[0008] In view of this, we propose a detection device for automotive central control screens. Summary of the Invention

[0009] The purpose of this invention is to provide a vehicle central control screen detection device to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides a vehicle central control screen testing device, comprising a support base, an operation box at the top of the support base, a testing platform inside the operation box, a rotating block at the bottom of the testing platform with toothed surfaces, a placement plate on the surface of the testing platform, a testing component above the placement plate, the testing component including a servo motor mounted on the side wall of the operation box, the output shaft of the servo motor passing through the operation box and having a lead screw at its end, a moving block on the surface of the lead screw, a first cylinder at the bottom of the moving block, a moving frame at the bottom of the first cylinder, an electric slide rail on the inner wall of the moving frame, a sliding block on the surface of the electric slide rail, a stylus below the sliding block, clamping components on both sides of the testing platform for clamping and fixing the screen to be tested, simulation components on both sides of the stylus, and an adjustment component between the testing platform and the operation box for adjusting the angle of the testing platform.

[0011] As a further improvement to this technical solution, an elastic plate is provided between the sliding block and the stylus. The stylus is fixed to the bottom of the elastic plate. When the stylus is subjected to external pressure, it squeezes the elastic plate to buffer the external pressure on the stylus.

[0012] As a further improvement to this technical solution, the clamping assembly includes cylindrical columns disposed on both sides of the testing platform, a sliding rod slidably disposed on the inner wall of the cylindrical column, a compression spring disposed between the cylindrical column and the sliding rod, and a clamping plate disposed at the end of the sliding rod, the clamping plate clamping and limiting the two sides of the central control screen.

[0013] As a further improvement to this technical solution, a groove is provided at the bottom of the column, and a toothed block is provided at the bottom of the slide rod, the toothed block sliding on the inner wall of the groove.

[0014] As a further improvement to this technical solution, an electric telescopic rod is provided below the column, and a toothed plate is provided at the end of the electric telescopic rod. The electric telescopic rod is controlled to drive the toothed plate to move vertically, and the toothed plate engages and fixes the toothed block.

[0015] As a further improvement to this technical solution, the simulation component includes a rotating motor disposed on both sides of the outer wall of the moving frame. The output end of the rotating motor is provided with an eccentric wheel. The eccentric wheel rotates on the surface of the elastic plate. When the eccentric wheel rotates, it reciprocates to squeeze the elastic plate, causing the stylus fixed at the bottom of the elastic plate to repeatedly press and detect the same position.

[0016] As a further improvement to this technical solution, the end of the eccentric wheel is provided with a drive gear, which rotates coaxially with the eccentric wheel. A secondary gear is provided on one side of the drive gear. When the drive gear rotates, it drives the secondary gear to mesh and rotate. A connecting rod is provided at the bottom of the secondary gear, a base plate is provided at the bottom of the connecting rod, and a nozzle is provided at the bottom of the base plate.

[0017] As a further improvement to this technical solution, the nozzles are arranged in an array on the bottom of the substrate, and the nozzles are at a 30° angle to the horizontal.

[0018] As a further improvement to this technical solution, the adjustment assembly includes a support block located at the bottom of the operation box, a support rod between the support blocks, a rotating block rotating on the surface of the support rod, a torsion spring on the surface of the support rod, and the two ends of the torsion spring being fixed to the side wall of the rotating block and the support block respectively. The rotating block is perpendicular to the horizontal plane due to the force of the torsion spring.

[0019] As a further improvement to this technical solution, the bottom of the rotating block is provided with a rack, and the moving rack drives the rotating block to rotate. The end of the rack is provided with a second cylinder, and the piston rod at the end of the second cylinder is controlled to drive the rack to move in the axial direction.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this automotive central control screen testing device, the electric telescopic rod is controlled to move the toothed plate vertically. The toothed plate moves to the bottom of the toothed block and limits it, thereby preventing the sliding rod from sliding and keeping the central control screen between the clamps in a fixed state, ensuring the accuracy of the test. After the test is completed, the electric telescopic rod is controlled to move the toothed plate away from the surface of the toothed block, which facilitates the quick loading and unloading of the central control screen.

[0022] 2. In this automotive central control screen testing device, the output shaft of the rotating motor drives the eccentric wheel to rotate. When the eccentric wheel rotates, it squeezes the elastic plate. The elastic plate reciprocates in the vertical direction under the force of the eccentric wheel. At this time, the stylus at the bottom of the elastic plate repeatedly presses the position to be inspected multiple times, thereby simulating the actual use scenario and obtaining test information. This facilitates the collection of the central control screen sensor response and the judgment of the central control screen quality, thus improving the practicality of the testing device.

[0023] 3. In this automotive central control screen testing device, the piston rod at the end of the second cylinder drives the rack to move axially. During the movement of the rack, the rotating block rotates, adjusting the central control screen placed on the surface of the rotating block. The device simulates the testing conditions of the central control screen under various scenarios by using a stylus to touch the tilted central control screen inspection position, thereby ensuring the accuracy of the test.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] The purpose of this embodiment is to provide a vehicle central control screen detection device, see reference. Figures 1-8As shown, the system includes a support base 100, an operation box 101 on top of the support base 100, a detection platform 102 inside the operation box 101, a rotating block 104 at the bottom of the detection platform 102 with toothed surfaces, a placement plate 103 on the surface of the detection platform 102, and a detection assembly 200 above the placement plate 103. The detection assembly 200 includes a servo motor 201 mounted on the side wall of the operation box 101, the output shaft of the servo motor 201 passing through the operation box 101 and having a lead screw 202 at its end, and a moving block 203 on the surface of the lead screw 202. The bottom of the moving block 203 is provided with a first cylinder 204, the bottom of the first cylinder 204 is provided with a moving frame 205, the inner wall of the moving frame 205 is provided with an electric slide rail 206, the surface of the electric slide rail 206 is provided with a sliding block 207, and a stylus 209 is provided below the sliding block 207. Clamping components 300 are provided on both sides of the detection table 102 to clamp and fix the screen to be tested. Simulation components 400 are provided on both sides of the stylus 209. An adjustment component 500 is provided between the detection table 102 and the operation box 101 to adjust the angle of the detection table 102.

[0041] During touchscreen testing of the central control screen, to prevent the stylus 209 from directly contacting the screen and applying hard pressure that could damage it, an elastic plate 208 is provided between the sliding block 207 and the stylus 209. The stylus 209 is fixed to the bottom of the elastic plate 208. When the stylus 209 is subjected to external pressure, it squeezes the elastic plate 208, buffering the external pressure on the stylus 209. During the testing of the central control screen, the output of the servo motor 201 drives the lead screw 202 to rotate, causing the moving block 203 to move on the surface of the lead screw 202, while simultaneously controlling the sliding block 207 to slide on the surface of the lead screw 202. The electric slide rail 206 positions the stylus 209 above the area to be tested. The first cylinder 204 controls the stylus 209 to move downwards. When the stylus 209 contacts the central control screen and continues to move downwards, the stylus 209 applies a set pressure value to the central control screen to simulate human operation. During the pressure application process between the stylus 209 and the central control screen, a reaction force is received, which causes the elastic plate 208 to move the stylus 209 in the opposite direction, buffering the pressure applied to the central control screen. This avoids the stylus 209 applying hard pressure to the central control screen during the testing process, thus ensuring the safety of the central control screen during the testing process.

[0042] Considering that the sensitivity of the touchscreen sensor of the central control screen also requires frequent sliding tests on the surface of the central control screen, and that the stylus 209 has friction with the surface of the central control screen during the sliding process, which can easily cause the central control screen placed on the surface of the testing platform 102 to slide, thus affecting the testing effect, the clamping assembly 300 includes cylindrical tubes 301 on both sides of the testing platform 102, with sliding rods 302 slidably mounted on the inner wall of the cylindrical tubes 301, and a compression spring 303 between the cylindrical tubes 301 and the sliding rods 302. A clamping plate 304 is provided at the end of the sliding rod 302, and the clamping plate 304 clamps the sides of the central control screen. The clamping and limiting mechanism works by pressing the clamping plate 304, which in turn pushes the slide rod 302 to slide against the inner wall of the cylinder 301. Simultaneously, the slide rod 302 compresses the compression spring 303 during its movement. As the clamping plates 304 move, the space between them increases, allowing the central control screen to be placed on the surface of the placement tray 103. When the clamping plate 304 is no longer pressed, the slide rod 302, under the restoring force of the compression spring 303, causes the clamping plate 304 to reset and limit the movement of the central control screen's side wall. This prevents screen movement from affecting the test results during the sliding detection of the central control screen surface.

[0043] To further improve the stability of the central control screen, a groove is provided at the bottom of the column 301, and a toothed block 305 is provided at the bottom of the slide rod 302. The toothed block 305 slides on the inner wall of the groove. An electric telescopic rod 306 is provided below the column 301, and a toothed plate 307 is provided at the end of the electric telescopic rod 306. The electric telescopic rod 306 is controlled to move the toothed plate 307 vertically. The toothed plate 307 engages and fixes the toothed block 305. When the two sides of the central control screen are squeezed and limited by the clamping plate 304, the electric telescopic rod 306 is controlled to move the toothed plate 307 vertically. The toothed plate 307 moves to the bottom of the toothed block 305 to limit it, thereby preventing the slide rod 302 from sliding and keeping the central control screen between the clamping plates 304 in a fixed state, ensuring the accuracy of the test. After the test is completed, the electric telescopic rod 306 is controlled to move the toothed plate 307 away from the surface of the toothed block 305, thereby facilitating the quick loading and unloading of the central control screen.

[0044] During the testing of the central control screen, to ensure the realism of the test, it is necessary to simulate different usage scenarios. For example, when operating the central control screen, users often repeatedly click on the touch-sensitive areas. To simulate this operation, the simulation component 400 includes a rotating motor 401 located on both sides of the outer wall of the moving frame 205. The output end of the rotating motor 401 is equipped with an eccentric wheel 402, which rotates on the surface of the elastic plate 208. When the eccentric wheel 402 rotates, it reciprocates and presses the elastic plate 208, causing the stylus 209 fixed at the bottom of the elastic plate 208 to repeatedly press on the surface of the elastic plate 208. Pressing tests are performed at the same location. When simulating human operation, the output shaft of the rotating motor 401 drives the eccentric wheel 402 to rotate. When the eccentric wheel 402 rotates, it squeezes the elastic plate 208. The elastic plate 208 reciprocates in the vertical direction under the force of the eccentric wheel 402. At this time, the stylus 209 located at the bottom of the elastic plate 208 repeatedly presses the position to be inspected, thereby simulating the actual use scenario and obtaining test information. This facilitates the collection of the central control screen sensor response and the judgment of the central control screen quality, thus improving the practicality of the testing device.

[0045] During the testing of the central control screen, when there is a lot of dust on the surface of the central control screen, it can easily affect the contact sensing between the stylus 209 and the central control screen, thus affecting the test results. Therefore, the end of the eccentric wheel 402 is provided with a drive gear 403, which rotates coaxially with the eccentric wheel 402. A secondary gear 404 is provided on one side of the drive gear 403. When the drive gear 403 rotates, it drives the secondary gear 404 to mesh and rotate. A connecting rod is provided at the bottom of the secondary gear 404, and a base plate 405 is provided at the bottom of the connecting rod. A nozzle 406 is provided at the bottom of the base plate 405. The nozzles 406 are arranged in an array at the bottom of the base plate 405. 406 forms a 30° angle with the horizontal. When the inspection position is tested, the rotation of the eccentric wheel 402 drives the coaxial rotation of the drive gear 403. The rotation of the drive gear 403 drives the meshing rotation of the secondary gear 404. The bottom of the secondary gear 404 is provided with a connecting rod, which passes through the elastic plate 208. The bottom of the connecting rod is provided with a base plate 405. Therefore, the connecting rod drives the base plate 405 to rotate coaxially. Since the bottom of the base plate 405 is provided with a nozzle 406, the nozzle 406 blows air around the test position of the central control screen during the rotation, thereby keeping the dust away from the test position and improving the testing accuracy of the stylus 209 on the central control screen.

[0046] When testing the central control screen, the stylus 209 is usually used to press the screen vertically. However, in actual use, the finger touches the central control screen at a certain angle. Therefore, the adjustment component 500 includes a support block 501 located at the bottom of the control box 101, a support rod between the support blocks 501, a rotating block 104 rotating on the surface of the support rod, and a torsion spring 502 on the surface of the support rod. The two ends of the torsion spring 502 are respectively fixed to the side wall of the rotating block 104 and the support block 501. The rotating block 104 is perpendicular to the horizontal plane due to the force of the torsion spring 502. A rack 503 is provided at the bottom of the rotating block 104. The rack 503 drives the rotating block 104 to rotate. The rack 503 is equipped with a second cylinder 504 at its end. The piston rod at the end of the second cylinder 504 is controlled to drive the rack 503 to move axially. When testing the inspection position of the central control screen, the piston rod at the end of the second cylinder 504 is controlled to drive the rack 503 to move axially. During the movement, the rack 503 drives the rotating block 104 to rotate, adjusting the central control screen placed on the surface of the rotating block 104. The stylus 209 is used to touch the tilted central control screen inspection position, thereby simulating the inspection conditions of the central control screen under multiple use scenarios, thus ensuring the accuracy of the inspection.

[0047] In practical use, the output of the servo motor 201 drives the lead screw 202 to rotate, causing the moving block 203 to move on the surface of the lead screw 202. At the same time, the sliding block 207 is controlled to slide on the surface of the electric slide rail 206, so that the stylus 209 is above the area to be tested. The first cylinder 204 is controlled to drive the stylus 209 to move downward. When the stylus 209 contacts the central control screen and continues to move downward, the stylus 209 applies a set pressure value to the central control screen to simulate human operation. During the pressure application process between the stylus 209 and the central control screen, it receives a reaction force, which causes the elastic plate 208 to drive the stylus 209 to move in the opposite direction, buffering the pressure applied to the central control screen. This avoids the stylus 209 applying hard pressure to the central control screen during the testing process, thus ensuring the safety of the central control screen during the testing process.

[0048] When the central control screen is squeezed and limited by the clamping plates 304 on both sides, the electric telescopic rod 306 is controlled to drive the toothed plate 307 to move vertically. The toothed plate 307 moves to the bottom of the toothed block 305 to limit it, thereby preventing the slide bar 302 from sliding and keeping the central control screen between the clamping plates 304 in a fixed state to ensure the accuracy of the test. After the test is completed, the electric telescopic rod 306 is controlled to drive the toothed plate 307 away from the surface of the toothed block 305, thereby facilitating the quick loading and unloading of the central control screen.

[0049] By controlling the output shaft of the rotating motor 401 to drive the eccentric wheel 402 to rotate, the eccentric wheel 402 compresses the elastic plate 208. The elastic plate 208 reciprocates vertically under the force of the eccentric wheel 402. At this time, the stylus 209 located at the bottom of the elastic plate 208 repeatedly presses the position to be inspected, thus simulating the actual usage scenario and obtaining test information. This facilitates the collection of data on the sensor response of the central control screen, making it easier to judge the quality of the central control screen, thereby improving the practicality of the testing device. When the eccentric wheel 402 rotates, it drives the drive gear 403 to rotate coaxially. When the drive gear 403 rotates, it drives the secondary gear 404 to mesh and rotate. The bottom of the secondary gear 404 is provided with a connecting rod, which passes through the elastic plate 208. The bottom of the connecting rod is provided with a base plate 405. Therefore, the connecting rod drives the base plate 405 to rotate coaxially. Since the bottom of the base plate 405 is provided with a nozzle 406, the nozzle 406 blows air around the test position of the central control screen during the rotation, thereby keeping the dust away from the test position and improving the test accuracy of the stylus 209 on the central control screen.

[0050] When testing the inspection position of the central control screen, the piston rod at the end of the second cylinder 504 is controlled to drive the rack 503 to move in the axial direction. During the movement, the rack 503 drives the rotating block 104 to rotate, adjusting the central control screen placed on the surface of the rotating block 104. The stylus 209 is used to touch the tilted central control screen inspection position, thereby simulating the inspection of the central control screen under multiple use scenarios, thus ensuring the accuracy of the inspection.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
