[0012] The knocking unit includes a rear plate. The rear plates are symmetrically arranged in two. Rectangular grooves are formed on the upper end faces of the two rear plates. A cylinder is slidably installed in the rectangular grooves through an electric slider. The telescopic ends of the cylinders on both sides are commonly fixedly installed on a central frame. A rotating rod is rotatably installed at the groove in the middle of the central frame. A T-shaped block slidably connected to the central frame is rotatably installed on the rotating rod.

An extension plate is fixedly installed on one side of the central frame. A rotating plate is rotatably installed on the extension plate close to the central frame through a motor. One side of the rotating plate slides in one of the knocking plates. A contact plate is rotatably installed below the knocking plate.

[0013] The extrusion unit includes a rectangular box. The cylinder at the lower part of the rectangular box is slidably connected to the circumferential groove through an electric slider. An electric push rod is fixedly installed on one side of the rectangular box. The telescopic end of the electric push rod is fixedly installed with an inclined block sliding on the bottom of the inner cavity of the rectangular box.

[0014] On the side of the L-shaped frame close to the instrument panel, fixing brackets are symmetrically installed.

An extrusion roller is rotatably installed on the front part frame away from the extrusion wheel through a motor.

[0015] Another object of the present invention is to provide an automatic testing method for an electronic instrument panel, including the following steps: S1: Instrument panel fixation: Before testing the instrument panel, first adjust the distance between the two outer cylinders according to the specifications of the instrument panel so that the outer cylinders and the round holes on the instrument panel are coaxial. Then, after docking the two round holes on the instrument panel with the two outer cylinders and moving them downward, the electric slider is turned on to drive the control board to rotate. When the control board rotates, the moving plate slides in the through groove through the arc-shaped groove until multiple moving plates slide to抵触 the side wall of the round hole of the instrument panel for fixation. Then, the electric slider is turned on to drive the lifting ring to move downward. When the lifting ring moves downward, the extrusion block extrudes the outer block. After being extruded, the outer block retracts and squeezes the inner block through the moving rod. The inner block retracts and squeezes the contact block. At this time, the U-shaped clamping plate moves to limit the upper and lower surfaces of the edge of the round hole of the instrument panel; S2: Hardness test of the middle part of the instrument panel: When knocking on the fixed instrument panel to detect its hardness, the electric slider is turned on to drive the cylinder to slide in the rectangular groove until the contact plate is located above the instrument panel. Then, the motor is turned on to drive the rotating plate to rotate. When the rotating plate rotates, it drives the knocking plate to knock up and down. At this time, the contact plate follows the knocking plate to knock on the surface of the instrument panel together. When the knocking plate rises, at this time, under the action of the spring, the knocking plate can also knock on the instrument panel multiple times. Rotating the rotating rod to make the T-shaped block slide can also adjust the knocking force of the knocking plate. When knocking on the instrument panel, the spring can make the instrument panel housing impact the contact plate, thus achieving multiple knocks. By raising and lowering the connecting ring to drive the spring to move, the impact force when the instrument panel is impacted can be adjusted; S3: Edge compression resistance test of one side panel: The electric slider is turned on to drive the cylinder to move away from one side of the instrument panel. At this time, the contact plate moves to the back of the instrument panel. Then the motor is turned on to drive the extrusion roller to squeeze the side wall of the instrument panel. The electric push rod is extended and retracted to drive the bevel block to slide. The bevel block pushes the roller to lift the vertical rod. At this time, the extrusion roller rotates and lifts up and down to squeeze the side wall of the instrument panel. At this time, the electric slider is turned on to drive the rectangular box to slide in the annular groove, thereby performing a compression test on the edge continuity of the instrument panel. At the same time, the motor is turned on to drive the drive rod to rotate. When the drive rod rotates, the extrusion wheel squeezes the contact wheel, so that the extrusion roller squeezes the outer wall of the instrument panel evenly, effectively solving the problem of being unable to perform a continuous compression test on the side edge of the instrument panel due to irregularity.

[0016] Beneficial effects of the present invention: 1. The present invention drives the control rod to rotate by turning on the motor, and the control rod rotates synchronously to drive the control plate to rotate. When the control plate rotates, the movable plate is pushed through the arc groove, so that the multiple movable plates are moved closer or farther away from each other. Finally, the side of the multiple movable plates that are farther away from each other is fixed against the circular hole in the middle of the instrument panel in the new energy vehicle. The movement of the multiple movable plates can fix the instrument panels of different specifications, thereby meeting the hardness test and compression test of the instrument panels of new energy vehicles of different specifications.

[0017] 2. In the present invention, after the instrument panel in the new energy vehicle is subjected to downward pressure, the inner cylinder moves downward, and the connecting plate moves downward synchronously in the buffer groove. At this time, the connecting ring moves downward to squeeze the spring. When the instrument panel does not receive pressure, the connecting ring slides upward. At this time, under the action of the spring, the instrument panel moves up and down multiple times, thereby causing the instrument panel to collide with the knocking unit multiple times. When performing a hardness test, the instrument panel is not only subjected to external knocking, but also under the action of an impact component, the instrument panel itself collides with the knocking unit, further increasing the frequency of knocking on the instrument panel.

[0018] 3. The present invention drives the lifting member to move up and down by rotating the threaded rod. At this time, the lifting member drives the connecting ring to move up and down synchronously through the telescopic tubes on both sides. The lifting and lowering of the connecting ring drives the spring above it to be compressed. The impact force of the instrument panel after being knocked is finally adjusted by the compression of the spring. When the connecting ring drives the spring to move upward, the impact amplitude of the instrument panel itself after being knocked is smaller, and vice versa.

[0019] 4. The present invention drives the knocking plate to knock up and down when the rotating plate rotates. At this time, the contact plate follows the knocking plate to knock on the surface of the instrument panel. When the knocking plate rises, the knocking plate can also knock on the instrument panel multiple times under the action of the spring, and the T-block is made to slide back and forth in the center frame by rotating the rotating rod. When the center frame slides, the knocking plates on both sides move synchronously. The movement of the knocking plates on both sides can adjust the knocking force on the surface of the instrument panel to meet the knocking requirements of different forces on the instrument panel.

[0020] 5. The present invention drives the driving rod to rotate by turning on the motor. When the driving rod rotates, the contact wheel is squeezed by the squeezing wheel, so that the front frame synchronously drives the squeezing roller to squeeze the side wall of the instrument panel. The squeezing roller is driven to rotate by turning on the motor so that it can rotate and squeeze the side wall of the instrument panel. Compared with the existing device, the rotary extrusion adopted by the present invention can effectively avoid the situation where the side wall of the instrument panel is damaged due to excessive impact force caused by direct push and extrusion, and the electric slider is turned on to drive the rectangular box to rotate in the annular groove, so as to perform a full and comprehensive extrusion test on the side wall of the instrument panel in the new energy vehicle.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] An automatic testing device for an electronic instrument panel. The testing device in the present invention is used to test the instrument panel in a new energy vehicle, specifically to test the hardness and compressive resistance of the instrument panel.

[0025] As Figure 1-11As shown, an electronic instrument panel automatic test device comprises a bottom plate 1, wherein an adjustment groove 10 is symmetrically opened in the middle of the upper end surface of the bottom plate 1, and a placement unit 2 for placing the instrument panel during testing is provided on the two adjustment grooves 10, and an annular groove 11 is provided on the bottom plate 1 outside the two adjustment grooves 10, and the placement unit comprises an outer cylinder 21 slidably installed in the adjustment groove 10, an inner cylinder 22 is sleeved inside the outer cylinder 21, an impact assembly is installed between the inner cylinder 22 and the outer cylinder 21, and the center of the inner cylinder 22 is slidable by an electric slider A regulating rod 222 is installed vertically, and a control plate 223 is fixedly installed in the middle of the regulating rod 222. An arc groove 224 is circumferentially provided on the control plate 223. A through groove 225 is provided on the inner tube 22 at the rear of the arc groove 224. A movable plate 23 sliding in the through groove 225 is slidably installed in the arc groove 224. The multiple movable plates 23 are used to abut and fix the side wall of the circular hole in the middle of the instrument panel. A knocking unit 3 is fixedly installed at the rear of the bottom plate 1, and an extrusion unit 4 is slidably installed in the annular groove 11 through an electric slider.

[0026] The motor is turned on to drive the regulating rod 222 to rotate, and when the regulating rod 222 rotates, the control plate 223 is driven to rotate synchronously. When the control plate 223 rotates, the movable plate 23 is pushed through the arc groove 224, so that the multiple movable plates 23 are moved closer or farther away from each other. Finally, the multiple movable plates 23 are fixed to the circular hole in the middle of the instrument panel on the side away from each other. The movement of the multiple movable plates 23 can fix instrument panels of different specifications, thereby meeting the hardness test and compression test of instrument panels of different specifications.

[0027] Through the setting of the annular groove 11, the extrusion unit 4 can rotate to perform an extrusion test on the side wall of the instrument panel, thereby facilitating the detection of the pressure resistance of the edge of the instrument panel, and effectively solving the problem that the existing device cannot perform extrusion detection on the side edge of the instrument panel due to the irregular shape of the instrument panel. The setting of the placement unit 2 can meet the subsequent detection of instrument panels of different specifications on one side after being fixed. The setting of the knocking unit 3 can knock on the surface of the instrument panel to detect its hardness. At the same time, the setting of the impact component can also make the instrument panel itself impact up and down when knocking on the instrument panel, further intensifying the test of the hardness of the instrument panel.

[0028] A central rod 20 is installed at the center of the upper end surface of the bottom plate 1 through motor rotation, and an adjustment plate 201 is fixedly installed on the upper end surface of the central rod 20. Push-pull plates 202 are hinged on both sides of the adjustment plate 201. The push-pull plates 202 on both sides are hinged to the outer cylinders 21 on both sides away from the adjustment plate 201.

[0029] When placing instrument panels of different specifications, since the spacing between the two circular holes in the middle of the instrument panels of different specifications is different, the motor is turned on to drive the center rod 20 to rotate. When the center rod 20 rotates, it simultaneously drives the regulating plate 201 to rotate. When the regulating plate 201 rotates, the push-pull plates 202 on both sides drive the outer cylinders 21 on both sides to move closer or farther away. Finally, the axis between the two outer cylinders 21 is adjusted to correspond one-to-one with the axis of the two circular holes on the instrument panel to be tested, so as to facilitate the docking and fixation of instrument panels of different specifications.

[0030] The impact assembly includes a buffer groove 210 annularly opened in the outer cylinder 21, a connecting plate 220 fixedly connected to the inner cylinder 22 is provided in the buffer groove 210, and a connecting ring 221 located outside the outer cylinder 21 is commonly installed on the side of the multiple connecting plates 220 away from the inner cylinder 22, and a lifting ring 211 located outside the outer cylinder 21 is provided at the lower part of the connecting ring 221, and a plurality of springs are commonly installed between the lifting ring 211 and the connecting ring 221.

[0031] When the instrument panel fixed on the placement unit 2 is knocked, the instrument panel is subjected to the downward pressure, and the inner cylinder 22 moves downward. At this time, the connecting plate 220 moves downward synchronously in the buffer groove 210. At this time, the connecting ring 221 moves downward to squeeze the spring. When the instrument panel does not receive pressure, the connecting ring 221 slides upward. At this time, under the action of the spring, the instrument panel moves up and down many times, thereby causing the instrument panel to collide with the knocking unit 3 many times. During the hardness test, the instrument panel is not only knocked externally, but also, under the action of an impact component, the instrument panel itself collides with the knocking unit 3, further increasing the frequency of knocking on the instrument panel.

[0032] A fixing ring 212 fixedly connected to the outer tube 21 is provided at the lower part of the connecting ring 221, and a bidirectional telescopic plate 213 is fixedly installed between the two fixing rings 212. A threaded rod 214 is rotatably installed with a thread in the middle part of the upper end surface of the bidirectional telescopic plate 213, and a lifting member 215 is rotatably installed with an external thread of the threaded rod 214. Telescopic tubes 216 are fixedly installed on both sides of the lifting member 215, and one end of the telescopic tube 216 away from the lifting member 215 is respectively connected to the lifting rings 211 on both sides.

[0033] Through the setting of the telescopic tube 216, when the distance between the two outer cylinders 21 is adjusted, one end of each of the two telescopic tubes 216 moves synchronously with the outer cylinders 21 on both sides. By rotating the threaded rod 214, the lifting member 215 is driven to lift and lower. At this time, the lifting member 215 synchronously drives the connecting ring 221 to move up and down through the telescopic tubes 216 on both sides. The lifting of the connecting ring 221 drives the spring above it to be compressed. Finally, the impact force after the dashboard is struck is adjusted through the compression of the spring. When the connecting ring 221 drives the spring to move upward, the impact amplitude of the dashboard's own up-and-down impact after being struck is smaller. On the contrary, the impact amplitude of the dashboard's up-and-down impact is larger.

[0034] Vertical grooves 226 are circumferentially formed on the outer wall of the inner cylinder 22. An elevating ring 227 is slidably installed between the vertical grooves 226 through electric sliders. The elevating ring 227 is located outside the inner cylinder 22 and sleeved on the inner cylinder 22. An extrusion block 228 is fixedly installed circumferentially on the lower end surface of the elevating ring 227. An outer block 232 is provided below the extrusion block 228. A moving rod 231 is slidably installed on one side of the inner cavity of the moving plate 23.

[0035] One end of the moving rod 231 is fixedly connected to the outer block 232. The end of the moving rod 231 away from the outer block 232 is fixedly installed with an inner block 233 located in the inner cavity of the moving plate 23. A spring is sleeved on the outer part of the moving rod 231. A contact block 234 is provided on one side of the inner block 233. A U-shaped clamping plate 24 is fixedly installed on the side of the contact block 234 away from the inner block 233. The U-shaped clamping plate 24 penetrates and slides in the moving plate 23.

[0036] By turning on the electric slider to drive the elevating ring 227 to move downward, when the elevating ring 227 moves downward, it squeezes the outer block 232 downward through the extrusion block 228. After being squeezed, the outer block 232 drives the moving rod 231 to retract. When the moving rod 231 retracts, it pushes the contact block 234 through the inner block 233. Since the contact block 234 and the inner block 233 are wedge-shaped, at this time, the contact block 234 synchronously drives the U-shaped clamping plate 24 to slide outward. Finally, the U-shaped clamping plate 24 clamps and limits the upper and lower surfaces at the circular hole of the dashboard, so that the dashboard remains stable after being struck.

[0037] The knocking unit 3 includes a rear plate 31, which is symmetrically arranged in two. A rectangular groove is opened on the upper end surface of the two rear plates 31, in which a cylinder 32 is slidably installed through an electric slider, and a center frame 33 is fixedly installed at the telescopic ends of the cylinders 32 on both sides. A rotating rod 34 is threadedly installed in the groove in the middle of the center frame 33, and a T-block 35 slidably connected to the center frame 33 is threadedly installed on the rotating rod 34. A rotating shaft is installed in the middle of the T-block 35, and knocking plates 36 are fixedly installed on both sides of the rotating shaft. An extension plate 37 is fixedly installed on one side of the center frame 33, and a rotating plate 38 is installed on the extension plate 37 near one side of the center frame 33 through motor rotation. One side of the rotating plate 38 slides in the knocking plate 36 on one side, and a contact plate 39 is rotatably installed at the lower part of the knocking plate 36, and a spring is installed between the contact plate 39 and the knocking plate 36.

[0038] When the motor is turned on, it drives the rotating plate 38 to rotate. When the rotating plate 38 rotates, it drives the knocking plate 36 to knock up and down. At this time, the contact plate 39 follows the knocking plate 36 to knock on the surface of the instrument panel. When the knocking plate 36 rises, the knocking plate 36 can also knock on the instrument panel multiple times under the action of the spring, and the T-block 35 is made to slide back and forth in the center frame 33 by rotating the rotating rod 34. When the center frame 33 slides, the knocking plates 36 on both sides move synchronously. The movement of the knocking plates 36 on both sides can adjust the knocking force on the surface of the instrument panel to meet the knocking requirements of different forces on the instrument panel.

[0039] The extrusion unit 4 includes a rectangular box 41, and the cylinder at the lower part of the rectangular box 41 is slidably connected to the annular groove 11 through an electric slider. An electric push rod 42 is fixedly installed on one side of the rectangular box 41, and the telescopic end of the electric push rod 42 is fixedly installed with a bevel block 43 that slides with the bottom of the inner cavity of the rectangular box 41. A vertical rod 44 is provided on the upper part of the bevel block 43. The vertical rod 44 penetrates and slides in the rectangular box 41. A roller 441 is rotatably installed at the lower part of the vertical rod 44 and the roller 441 is always in contact with the bevel block 43. A traction rod 442 is fixedly installed on one side of the upper end surface of the rectangular box 41, and an L-shaped frame 45 is fixedly installed on the upper end surface of the traction rod 442 and the vertical rod 44.

[0040] A fixing frame 451 is symmetrically installed on the L-shaped frame 45 close to the instrument panel, a driving rod 452 is installed between the upper and lower fixing frames 451 through the rotation of a motor, an extrusion wheel 453 is fixedly installed in the middle of the driving rod 452, a T-shaped built-in rod 454 is slidably installed in the fixing frame 451, a sleeve is provided on the outside of the built-in rod 454 and a spring is located in the inner cavity of the fixing frame 451, a front frame 46 is fixedly installed on one end of the two built-in rods 454 away from the fixing frame 451, a contact wheel 461 is rotatably installed on the front frame 46 close to the extrusion wheel 453, and an extrusion roller 47 is installed on the front frame 46 away from the extrusion wheel 453 through the rotation of a motor.

[0041] The motor is turned on to drive the driving rod 452 to rotate. When the driving rod 452 rotates, it squeezes the contact wheel 461 through the squeezing wheel 453, so that the front frame 46 synchronously drives the squeezing roller 47 to squeeze the side wall of the instrument panel. The motor is turned on to drive the squeezing roller 47 to rotate, so that it rotates and squeezes the side wall of the instrument panel. Compared with the existing device, the rotational squeezing adopted by the present invention can effectively avoid the situation that the instrument panel is damaged due to excessive impact force on the side wall of the instrument panel caused by direct pushing and squeezing. And by turning on the electric slider to drive the rectangular box 41 to rotate in the circumferential groove 11, a full and comprehensive squeezing test can be carried out on the side wall of the instrument panel.

[0042] Another object of the present invention is to provide an automatic testing method for an electronic instrument panel, including the following steps: S1: Instrument panel fixation: Before testing the instrument panel, first adjust the distance between the two outer cylinders 21 according to the specifications of the instrument panel so that the outer cylinders 21 and the round holes on the instrument panel are coaxial. Then, after docking the two round holes on the instrument panel with the two outer cylinders 21 and moving them downward, the electric slider is turned on to drive the control board 223 to rotate. When the control board 223 rotates, it drives the moving board 23 to slide in the through groove 225 through the arc groove 224 until multiple moving boards 23 slide to抵触 fix the side wall of the round hole of the instrument panel. Then, the electric slider is turned on to drive the lifting ring 227 to move downward. When the lifting ring 227 moves downward, the extrusion block 228 squeezes the outer block 232. After the outer block 232 is squeezed, it retracts and squeezes the inner block 233 through the moving rod 231. The inner block 233 retracts and squeezes the contact block 234. At this time, the U-shaped clamping plate 24 moves to limit the upper and lower surfaces of the edge of the round hole of the instrument panel; S2: Hardness test of the middle part of the instrument panel: When the fixed instrument panel is knocked to detect its hardness, the electric slider is turned on to drive the cylinder 32 to slide in the rectangular groove until the contact plate 39 is located above the instrument panel. Then, the motor is turned on to drive the rotating plate 38 to rotate. When the rotating plate 38 rotates, it drives the knocking plate 36 to knock up and down. At this time, the contact plate 39 follows the knocking plate 36 to knock on the surface of the instrument panel together. When the knocking plate 36 rises, at this time, under the action of the spring, the knocking plate 36 can also knock on the instrument panel multiple times. Rotating the rotating rod 34 to make the T-shaped block 35 slide can also control the knocking force of the knocking plate 36. When knocking on the instrument panel, through the setting of the spring, the instrument panel housing can impact the contact plate 39 to achieve multiple knocks. By lifting and lowering the connecting ring 221 to drive the spring to move, the impact force during the impact of the instrument panel can be controlled; S3: Compressive strength test of the edge of one side plate: The electric slider is activated to drive the cylinder 32 to move away from the side of the instrument panel. At this time, the contact plate 39 moves to the rear of the instrument panel. Subsequently, the motor is activated to drive the extrusion roller 47 to extrude the side wall of the instrument panel. The electric push rod 42 expands and contracts to drive the bevel block 43 to slide. The bevel block 43 pushes the roller 441 to raise and lower the vertical rod 44. At this time, the extrusion roller 47 rotates while moving up and down to fold and extrude the side wall of the instrument panel. At this time, the electric slider is activated to drive the rectangular box 41 to slide in the circumferential groove 11, so as to perform a compressive resistance test on the edge continuity of the instrument panel. At the same time, the motor is activated to drive the drive rod 452 to rotate. When the drive rod 452 rotates, the extrusion wheel 453 extrudes the contact wheel 461, so that the extrusion roller 47 evenly extrudes the outer wall of the instrument panel, effectively solving the problem that the continuous compressive resistance test cannot be carried out due to the irregular side edge of the instrument panel.

[0043] When the present invention is in use, the distance between the two outer cylinders 21 is adjusted according to the specifications of the instrument panel, so that the outer cylinders 21 and the round holes on the instrument panel are on the same axis. Subsequently, the two round holes on the instrument panel are docked with the two outer cylinders 21 and then moved down. The motor is activated to drive the central rod 20 to rotate. When the central rod 20 rotates, it synchronously drives the regulation plate 201 to rotate. When the regulation plate 201 rotates, it drives the two outer cylinders 21 on both sides to move closer or farther away through the push-pull plates 202 on both sides. Finally, the axis between the two outer cylinders 21 is adjusted to correspond one by one with the axes of the two round holes on the instrument panel to be tested. The motor is activated to drive the regulation rod 222 to rotate. When the regulation rod 222 rotates, it synchronously drives the control plate 223 to rotate. When the control plate 223 rotates, it pushes the moving plate 23 through the arc-shaped groove 224, so that the multiple moving plates 23 move closer or farther away from each other. Finally, the sides of the multiple moving plates 23 that move away from each other abut and fix the round hole in the middle of the instrument panel. The electric slider is activated to drive the lifting ring 227 to move down. When the lifting ring 227 moves down, it squeezes the outer block 232 downward through the extrusion block 228. After being squeezed, the outer block 232 drives the moving rod 231 to retract. When the moving rod 231 retracts, it pushes the contact block 234 through the inner block 233. Since the contact block 234 and the inner block 233 are wedge-shaped, at this time, the contact block 234 synchronously drives the U-shaped clamping plate 24 to slide outward. Finally, the U-shaped clamping plate 24 clamps and limits the upper and lower surfaces of the round hole of the instrument panel, so that the instrument panel remains stable after being knocked; The motor is turned on to drive the rotating plate 38 to rotate, and when the rotating plate 38 rotates, it drives the knocking plate 36 to knock up and down. At this time, the contact plate 39 follows the knocking plate 36 to knock on the surface of the instrument panel. When the knocking plate 36 rises, the knocking plate 36 can also knock on the instrument panel multiple times under the action of the spring, and the T-block 35 is made to slide back and forth in the center frame 33 by rotating the rotating rod 34. When the center frame 33 slides, the knocking plates 36 on both sides move synchronously. The movement of the knocking plates 36 on both sides can adjust the knocking force on the surface of the instrument panel to meet the different forces of the instrument panel. When the instrument panel is subjected to the downward force, the inner cylinder 22 moves downward, and the connecting plate 220 moves downward synchronously in the buffer groove 210. At this time, the connecting ring 221 moves downward to squeeze the spring. When the instrument panel does not receive the pressure, the connecting ring 221 slides upward. At this time, under the action of the spring, the instrument panel moves up and down for many times, so that the instrument panel collides with the knocking unit 3 for many times. When the hardness test is performed, the instrument panel is not only knocked by the external connection, but also, under the action of an impact component, the instrument panel itself collides with the knocking unit 3, which further increases the frequency of knocking on the instrument panel. The threaded rod 214 is rotated to drive the lifting member 215 to move up and down. At this time, the lifting member 215 synchronously drives the connecting ring 221 to move up and down through the telescopic tubes 216 on both sides. The lifting and lowering of the connecting ring 221 drives the spring above it to be compressed. The impact force of the instrument panel after being knocked is finally adjusted by the compression of the spring. When the connecting ring 221 drives the spring to move upward, the impact amplitude of the instrument panel itself after being knocked is smaller, and vice versa. The impact amplitude of the instrument panel's up and down impact is larger. When the driving rod 452 rotates, the extrusion wheel 453 squeezes the contact wheel 461, so that the front frame 46 synchronously drives the extrusion roller 47 to squeeze the side wall of the instrument panel. The extrusion roller 47 is driven to rotate by the motor to rotate the side wall of the instrument panel. Compared with the existing device, the rotary extrusion adopted by the present invention can effectively avoid the situation that the side wall of the instrument panel is damaged due to excessive impact force caused by direct pushing and extrusion, and the electric slider is opened to drive the rectangular box 41 to rotate in the annular groove 11, so that the side wall of the instrument panel can be fully and comprehensively extruded. Test.

10. An automated testing method for an electronic instrument panel, using the automated testing device for an electronic instrument panel as claimed in claim 9 to test the instrument panel, characterized in that: The test method includes the following steps: S1: Fixing the instrument panel: Before testing the instrument panel, first adjust the distance between the two outer cylinders (21) according to the specifications of the instrument panel so that the outer cylinders (21) and the round holes on the instrument panel are on the same axis. Then, move the instrument panel down after docking the two round holes on the instrument panel with the two outer cylinders (21). Subsequently, the electric slider is turned on to drive the control board (223) to rotate. When the control board (223) rotates, it drives the moving board (23) to slide in the through groove (225) through the arc groove (224) until the plurality of moving boards (23) slide to abut against the side wall of the round hole of the instrument panel for fixing. Then, the electric slider is turned on to drive the lifting ring (227) to move down. When the lifting ring (227) moves down, the extrusion block (228) extrudes the outer block (232). After being extruded, the outer block (232) retracts and squeezes the inner block (233) through the moving rod (231). The inner block (233) retracts and squeezes the contact block (234). At this time, the U-shaped clamping plate (24) moves to limit the upper and lower surfaces of the edge of the round hole of the instrument panel. S2: Testing the hardness in the middle of the instrument panel: When the fixed instrument panel is struck to detect its hardness, the electric slider is turned on to drive the cylinder (32) to slide in the rectangular groove until the contact plate (39) is located above the instrument panel. Then, the motor is turned on to drive the rotating plate (38) to rotate. When the rotating plate (38) rotates, it drives the striking plate (36) to strike up and down. At this time, the contact plate (39) follows the striking plate (36) to strike the surface of the instrument panel together. When the striking plate (36) rises, under the action of the spring, the striking plate (36) can also strike the instrument panel multiple times. Rotating the rotating rod (34) to make the T-shaped block (35) slide can also adjust the striking force of the striking plate (36). When striking the instrument panel, the spring can make the instrument panel housing strike the contact plate (39) to achieve multiple strikes. The spring moves by driving the connection ring (221) to lift and lower, thereby adjusting the impact force when the instrument panel is impacted. S3: Testing the edge compression resistance of one side panel: The electric slider is turned on to drive the cylinder (32) to move away from one side of the instrument panel. At this time, the contact plate (39) moves to the rear of the instrument panel. Subsequently, the motor is turned on to drive the squeezing roller (47) to squeeze the side wall of the instrument panel. The electric push rod (42) is extended and retracted to drive the bevel block (43) to slide. The bevel block (43) pushes the roller (441) to lift the vertical rod (44). At this time, the squeezing roller (47) is lifted and lowered while rotating to squeeze the side wall of the instrument panel. At this time, the electric slider is turned on to drive the rectangular box (41) to slide in the annular groove (11), thereby performing a compression test on the continuity of the edge of the instrument panel. At the same time, the motor is turned on to drive the driving rod (452) to rotate. When the driving rod (452) rotates, the squeezing wheel (453) squeezes the contact wheel (461), so that the squeezing roller (47) squeezes the outer wall of the instrument panel evenly, effectively solving the problem that the continuous compression test cannot be performed on the side edge of the instrument panel due to its irregularity.
