Description

Technical Field

[0001] The present invention relates to the field of central control screen detection technology, and in particular to a vehicle central control screen detection device. Background Art

[0002] With the rapid development of the automotive industry, the degree of automotive intelligence continues to improve. The car central control screen has become a core component of the vehicle's human-computer interaction system. Among them, the touch screen sensor is a key component for realizing interaction between the user and the central control screen. Its performance directly affects the user experience as well as the convenience and safety of vehicle operation. Therefore, accurate and efficient detection of the car central control screen touch screen sensor is of vital importance.

[0003] There are many existing technologies for detection devices, such as: Chinese patent publication number CN116699195B discloses a car central control screen detection device, including a main body mechanism, on which a hanging mechanism is slidably provided; an adjusting mechanism is rotatably provided on the main body mechanism; the adjusting mechanism and the fixing mechanism are cooperatively connected; a driving mechanism is rotatably provided on the main body mechanism; the driving mechanism and the clamping mechanism are cooperatively connected; the central control screen is placed in the middle of the clamping mechanism, the clamping mechanism is started to fix the central control screen when sliding, and the driving mechanism is rotated to drive the central control screen to flip, thereby facilitating the removal of the central control screen back cover during detection; after the main board is taken out of the central control screen, the fixing mechanism is started to fix the main board, and the adjusting mechanism is rotated to adjust the placement angle of the main board when detecting; the hanging mechanism is pulled out from the main body mechanism, thereby facilitating the placement of tools used during detection, and the main body mechanism can also store the bolts removed from the back cover.

[0004] However, there are still some problems in actual use: 1. Traditional central control screen testing relies heavily on manual operation. Inspectors must frequently and individually touch the screen to test various functions, such as screen response speed and touch sensitivity. This manual testing method greatly limits testing efficiency. As automobile production continues to expand, it is difficult to meet the needs of large-scale, high-efficiency production testing, severely restricting the overall progress of automobile manufacturing and increasing production costs. 2. During actual driving, the driver may interact with the central control screen under different environmental conditions. The current detection process often only performs simple functional tests under conventional conditions, ignoring the impact of these complex and changeable actual usage scenarios on the central control screen touch screen performance. For example, when operating the central control screen, people often repeatedly click on the location where the screen needs to be touched. If such operations are not tested and identified, it is easy to affect the accuracy of the central control screen test inspection.

[0005] In view of this, we propose a car central control screen detection device. Summary of the Invention

[0018] 2. In the automobile central control screen detection device, the eccentric wheel is driven to rotate by controlling the output shaft of the rotating motor. When the eccentric wheel rotates, it squeezes the elastic plate. The elastic plate is subjected to the force of the eccentric wheel and reciprocates in the vertical direction.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] The purpose of this embodiment is to provide a vehicle central control screen detection device, see Figures 1-8 As shown, it includes a support base 100, an operation box 101 is provided on the top of the support base 100, a detection platform 102 is provided inside the operation box 101, a rotating block 104 is provided at the bottom of the detection platform 102, a surface of the rotating block 104 is provided with a tooth pattern, a placement plate 103 is provided on the surface of the detection platform 102, a detection component 200 is provided above the placement plate 103, and the detection component 200 includes a servo motor 201 provided on the side wall of the operation box 101, an output shaft of the servo motor 201 passes through the operation box 101 and is provided with a screw rod 202 at the end thereof, a moving block 203 is provided on the surface of the screw rod 202, and a moving block 203 is provided on the surface of the moving block 203. A first cylinder 204 is provided at the bottom of the moving block 203, a moving frame 205 is provided at the bottom of the first cylinder 204, an electric slide rail 206 is provided on the inner wall of the moving frame 205, a sliding block 207 is provided on the surface of the electric slide rail 206, a stylus 209 is provided under the sliding block 207, clamping components 300 are provided on both sides of the testing platform 102, the clamping components 300 clamp and fix the screen to be tested, simulation components 400 are provided on both sides of the stylus 209, and an adjustment component 500 is provided between the testing platform 102 and the operation box 101, and the adjustment component 500 adjusts the angle of the testing platform 102.

[0025] When testing the touch screen of the central control screen, in order to prevent the stylus 209 from directly contacting the screen and exerting hard pressure to cause damage to the screen, an elastic plate 208 is provided between the sliding block 207 and the stylus 209. The stylus 209 is fixed at the bottom of the elastic plate 208. When the stylus 209 is subjected to external pressure, the elastic plate 208 is squeezed to buffer the external pressure on the stylus 209. When testing the central control screen, the output end of the servo motor 201 is controlled to drive the screw rod 202 to rotate, so that the moving block 203 moves on the surface of the screw rod 202, and at the same time, the sliding block 207 is controlled to slide on the surface of the screw rod 202. The surface of the electric slide rail 206 places the stylus 209 above the area to be detected, and controls the first cylinder 204 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 process of the stylus 209 applying pressure to the central control screen, it is subjected to a reaction force, so that the elastic plate 208 drives the stylus 209 to move in the opposite direction, buffering the pressure applied to the central control screen, thereby avoiding the stylus 209 applying hard pressure to the central control screen during the detection process, thereby ensuring the safety of the central control screen during the detection process.

[0026] Considering that when testing the sensitivity of the touch screen sensor of the central control screen, it is also necessary to frequently perform sliding tests on the surface of the central control screen. During the sliding process, the stylus 209 has friction with the surface of the central control screen, which can easily cause the central control screen placed on the surface of the test platform 102 to slide, thereby affecting the detection effect. Therefore, the clamping assembly 300 includes a column 301 provided on both sides of the test platform 102, a sliding rod 302 is provided on the inner wall of the column 301 for sliding, a compression spring 303 is provided between the column 301 and the sliding rod 302, and a clamping plate 304 is provided at the end of the sliding rod 302. The clamping plate 304 is provided on both sides of the central control screen. The clamping limit is achieved by squeezing the splint 304. The splint 304 is subjected to pressure to push the slide bar 302 to slide on the inner wall of the column 301. At the same time, the slide bar 302 squeezes the compression spring 303 during the movement. Since the splint 304 increases the space between them during the movement, the central control screen is placed on the surface of the placement plate 103, and the squeezing of the splint 304 is stopped. The slide bar 302 is subjected to the recovery force of the compression spring 303 to drive the splint 304 to reset and limit the side wall of the central control screen, thereby avoiding the screen movement affecting the test results when the sliding detection of the central control screen surface is carried out.

[0027] When the cam 302 is in the locked position, the cam 302 is in the locked position, and the cam 302 is locked, so that the cam 302 can be locked.

[0028] In the process of testing the central control screen, in order to obtain the authenticity of the test, it is necessary to simulate its different usage scenarios. For example, when operating the central control screen, people often click repeatedly on the position where the touch screen is needed. In order to simulate this operation, the simulation component 400 includes a rotating motor 401 provided on both sides of the outer wall of the moving frame 205. The output end of the rotating motor 401 is provided with an eccentric wheel 402. The eccentric wheel 402 rotates on the surface of the elastic plate 208. When the eccentric wheel 402 rotates, it reciprocates and squeezes the elastic plate 208, so that the stylus 209 fixed at the bottom of the elastic plate 208 repeatedly presses the elastic plate 208. The press detection is performed at the same position. When simulating human operation, the eccentric wheel 402 is driven to rotate by controlling the output shaft of the rotating motor 401. When the eccentric wheel 402 rotates, it squeezes the elastic plate 208. The elastic plate 208 is subjected to the force of the eccentric wheel 402 and reciprocates in the vertical direction. At this time, the stylus 209 at the bottom of the elastic plate 208 performs repeated press tests on the position to be inspected, thereby simulating the actual usage scenario and obtaining test information, which is convenient for collecting the response of the central control screen sensor and facilitating the judgment of the quality of the central control screen, thereby improving the practicality of the detection device.

[0029] During the test of the central control screen, if there is a lot of dust on the surface of the central control screen, it is easy to affect the contact sensing between the stylus 209 and the central control screen, thereby affecting the test results. Therefore, a driving gear 403 is provided at the end of the eccentric wheel 402. The driving gear 403 rotates coaxially with the eccentric wheel 402. A sub-gear 404 is provided on one side of the driving gear 403. When the driving gear 403 rotates, the sub-gear 404 is driven to engage and rotate. A connecting rod is provided at the bottom of the connecting rod, a base plate 405 is provided at the bottom of the base plate 405, and 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 an angle of 30° with the horizontal. When the inspection position is inspected, when the eccentric wheel 402 rotates, it drives the driving gear 403 to rotate coaxially. When the driving gear 403 rotates, it drives the sub-gear 404 to engage and rotate. A connecting rod is provided at the bottom of the sub-gear 404. The connecting rod passes through the elastic plate 208. A base plate 405 is provided at the bottom of the connecting rod. Therefore, the connecting rod drives the base plate 405 to rotate coaxially. Since a nozzle 406 is provided at the bottom of the base plate 405, the nozzle 406 blows air around the test position of the central control screen during the rotation process, thereby keeping dust away from the test position and improving the test accuracy of the stylus 209 on the central control screen.

[0030] When testing the central control screen, the stylus 209 is usually used to press the central control screen vertically. However, in actual use, the finger contacts the central control screen at a certain angle. Therefore, the adjustment component 500 includes a support block 501 provided at the bottom of the operation box 101, a support rod is provided between the support blocks 501, the rotating block 104 rotates on the surface of the support rod, and a torsion spring 502 is provided on the surface of the support rod. The two ends of the torsion spring 502 are respectively fixed to the rotating block 104 and the side wall of the support block 501. The rotating block 104 is subjected to the force of the torsion spring 502 and is perpendicular to the horizontal plane. A rack 503 is provided at the bottom of the rotating block 104. The rack 503 drives the rotating block 104 to rotate. A second cylinder 504 is provided at the end of the rack 503. The piston rod at the end of the second cylinder 504 is controlled to drive the rack 503 to move in the axial direction. 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, and the central control screen placed on the surface of the rotating block 104 is adjusted. By starting to work and touching the tilted central control screen inspection position with the stylus 209, the detection condition of the central control screen in a multi-use scenario is simulated, thereby ensuring the accuracy of the detection.

[0031] During specific use, the output end of the servo motor 201 is controlled to drive the screw rod 202 to rotate, so that the moving block 203 moves on the surface of the screw rod 202, and 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 detected, and 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 process of applying pressure between the stylus 209 and the central control screen, a reaction force is applied, so that the elastic plate 208 drives the stylus 209 to move in the opposite direction, buffering the pressure applied to the central control screen, thereby avoiding the stylus 209 applying hard pressure to the central control screen during the detection process, thereby ensuring the safety of the central control screen during the detection process; When the two sides of the central control screen are squeezed and limited by the splint 304, the tooth plate 307 is driven to move up in the vertical direction by controlling the electric telescopic rod 306, and the tooth plate 307 moves to the bottom of the tooth block 305 to limit it, thereby preventing the sliding of the slide bar 302, so that the central control screen between the splints 304 is always in a fixed state, ensuring the accuracy of the test. When the test is completed, the electric telescopic rod 306 is controlled to drive the tooth plate 307 away from the surface of the tooth block 305, thereby facilitating the rapid loading and unloading of the central control screen. By controlling the output shaft of the rotating motor 401 to drive the eccentric wheel 402 to rotate, the eccentric wheel 402 squeezes the elastic plate 208 when it rotates. The elastic plate 208 is subjected to the force of the eccentric wheel 402 and reciprocates in the vertical direction. At this time, the stylus 209 provided at the bottom of the elastic plate 208 performs repeated pressing tests on the position to be inspected, thereby simulating the actual usage scenario and obtaining test information, thereby facilitating the collection of the response of the central control screen sensor and facilitating the judgment of the quality of the central control screen, thereby improving the practicality of the detection device. When the eccentric wheel 402 rotates, it drives the driving gear 403 to rotate coaxially. When the driving gear 403 rotates, it drives the pinion 404 to rotate in meshing engagement. A connecting rod is provided at the bottom of the pinion 404. The connecting rod passes through the elastic plate 208. A base plate 405 is provided at the bottom of the connecting rod. Therefore, the connecting rod drives the base plate 405 to rotate coaxially. Since a nozzle 406 is provided at the bottom of the base plate 405, the nozzle 406 blows air around the test position of the central control screen during the rotation process, thereby keeping dust away from the test position and improving the test accuracy of the central control screen by the stylus 209. When testing the inspection position of the central control screen, the rack 503 is driven to move in the axial direction by controlling the piston rod at the end of the second cylinder 504. The rack 503 drives the rotating block 104 to rotate during the movement, and the central control screen placed on the surface of the rotating block 104 is adjusted. The stylus 209 is used to touch the tilted inspection position of the central control screen, thereby simulating the detection condition of the central control screen in a multi-use scenario, thereby ensuring the accuracy of the detection.
