Description

Technical Field

[0001] The present invention relates to the field of cockpit testing equipment, and in particular to a durability testing device for an intelligent cockpit of a new energy vehicle. Background Art

[0002] The intelligent cockpit of a new energy vehicle (NEV) is a highly intelligent driving and passenger space built within a NEV by integrating hardware, software, and network connectivity. Centered around the driver and passengers, it deeply integrates human-computer interaction, environmental perception, data processing, and other technologies to provide a safe, comfortable, convenient, and personalized travel experience.

[0003] When testing the cockpit, the test site needs to be frequently adjusted according to different test requirements, simulation scenarios, and equipment layouts. If the cockpit is fixed in the test site, it is difficult to move the cockpit flexibly, resulting in frequent movement of the cockpit by staff and position adjustments during cockpit testing. This extends the entire test cycle, increases test costs, and significantly reduces test efficiency. In daily driving, seats face frequent adjustments. Drivers may adjust the seat's fore-and-aft position, backrest angle, cushion height, etc. multiple times in a short period of time due to different driving needs. The lack of a reciprocating endurance fatigue test mechanism makes it impossible to determine whether the seat's fixed structure is stable under the repeated action of such lateral forces, and whether the seat filling will shift. This results in an extremely one-sided reliability assessment of the seat in actual use, making it impossible to accurately determine whether the seat can meet the user's long-term use needs, further increasing production costs. The lack of a pressure testing mechanism makes it impossible to simulate the pressure exerted on the seat by users of different weights and sitting postures, making it difficult to detect whether the seat's fixing structure is stable and whether the seat frame can withstand the corresponding pressure without deformation or breakage. As a result, R&D personnel can only explore through continuous trial and error, which prolongs the R&D cycle and increases R&D costs. Equipment failures during operation increase equipment maintenance costs and downtime. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, through the provision of a sliding support mechanism, can solve the problem that when testing the cockpit, staff members frequently need to move and adjust the cockpit, which prolongs the entire test cycle, increases test costs, and significantly reduces test efficiency. When conducting a durability test on the intelligent cockpit of a new energy vehicle, the cockpit is first fixed to the test bench through a screw connection between the base frame and the first support plate. Then, according to the test requirements, the cockpit is pushed so that the first pulley rolls on the first guide rail, and the rotating wheel rolls in the slide groove to achieve the sliding of the cockpit. During the sliding process, the elastic buffer structure will cushion and protect the cockpit according to actual conditions. By continuously repeating the sliding operation of the cockpit, the frequent movement and position adjustment of the intelligent cockpit in actual use is simulated, thereby testing and evaluating the durability of the cockpit. During the test process, it can be combined with other test equipment and methods to monitor and analyze the various performance indicators of the cockpit in real time to obtain more accurate test results, thereby effectively improving the overall test efficiency, extending the service life of the device, and ensuring the continuity of the test work.

[0015] 2. The reciprocating fatigue test mechanism addresses the issue of limited reliability assessments in actual seat use, preventing accurate assessments of whether the seat can meet user needs over the long term, and further increasing production costs. A motor drives the pulley and belt, causing the first slider to slide back and forth on the second guide rail. The first slider's motion is transmitted to the cabin via a first hydraulic rod, an extension rod, and a clamping plate, causing the cabin to reciprocate left and right. During this process, the sliding support mechanism provides stable support and cushioning for the cabin, ensuring smooth testing. By repeatedly performing the cabin's left-right reciprocating motion, the system simulates the frequent movement and vibration experienced in actual use, comprehensively testing and evaluating the cabin's structural strength and component durability. Furthermore, the system can be combined with other testing equipment and methods to monitor and analyze various cabin performance indicators in real time, resulting in more accurate test results. This effectively improves protection in side impacts, reduces safety risks, ensures seat reliability and safety, and enhances overall product quality.

[0016] 3. The third guide rail, bearing plate, second hydraulic rod, cylinder, circular plate, retaining ring, and impact sandbags eliminate the problem of R&D personnel relying solely on trial and error, which can extend R&D cycles, increase R&D costs, and cause equipment failures during operation, increasing maintenance costs and downtime. During testing, the bearing plate and impact sandbags are first adjusted to the appropriate height according to test requirements by controlling the extension and retraction of the second hydraulic rod. The cylinder is then activated, causing it to extend and retract at a preset frequency and stroke. The extension and retraction of the cylinder drives the circular plate up and down, which in turn, via the connecting rope, causes the impact sandbags to impact the smart cockpit in a regular manner. During the impact process, monitoring equipment records the cockpit's response, such as deformation and stress distribution, in real time, to assess its durability and reliability. The entire device works in coordination through the height adjustment of the hydraulic rod and the impact action of the cylinder, providing a comprehensive and accurate vertical pressure and impact testing environment for the smart cockpit, thereby effectively reducing equipment maintenance costs and downtime, improving the overall testing capabilities and work efficiency of the equipment, reducing the defective rate in the production process, and further reducing production costs.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 5 As shown: A durability testing device for an intelligent cockpit of a new energy vehicle includes a test bench 1. The upper side walls of the test bench 1 are fixedly connected to brackets 4, and the tops of the four brackets 4 are fixedly connected to top plates 5. The brackets 4 on the top of the upper side walls of the test bench 1 are used to support the bottom of the top plate 5, thereby forming a test bench similar to a box.

[0022] The upper side wall of the test bench 1 is provided with a cabin 8, and the bottom of the cabin 8 is fixedly connected to the base frame 9; the upper side wall of the test bench 1 is provided with a sliding support mechanism 2, which includes: a base 201, a first support plate 203, two slide grooves 205 and a nut 215. The bottom of the base 201 is fixedly connected to the middle of the upper side wall of the test bench 1, and the upper side wall of the base 201 is fixedly connected to the first guide rail 202. The base 201 is fixed to the middle of the upper side wall of the test bench 1 to support the bottom of the first guide rail 202 at the top, thereby providing a bottom sliding track for the top cabin 8. The first guide rail 202 and the base 201 are fixedly connected with first limiting plates 216 on both sides, and the upper side wall of the first support plate 203 is threadedly connected to the bottom of the base frame 9. The bottom wall of the first support plate 203 is fixedly connected with eight first pulleys 204 on both sides. The outer sides of the eight first pulleys 204 are arranged in the front and rear hole grooves of the first guide rail 202 before testing the cabin 8. By connecting the base frame 9 at the bottom of the cabin 8 with the first support plate 203 before testing the cabin 8, the cabin 8 is fixed on the first support plate 203. After fixation, the first pulley 204 at the bottom of the first support plate 203 will slide in the front and rear hole grooves of the first guide rail 202, thereby facilitating the adjustment of the position of the cabin 8, and limiting the first pulley 204 by the first limiting plates 216 to prevent the first pulley 204 from detaching from the inside of the first guide rail 202.

[0023] Two slide grooves 205 are both opened on the upper side wall of the test bench 1. The two slide grooves 205 are set on the front and rear sides of the base 201. Two first connecting rods 206 are set inside each slide groove 205. The front and rear ends of the four first connecting rods 206 are rotatably connected to two rotating wheels 207. The opened slide grooves 205 enable the first connecting rods 206 and the rotating wheels 207 to slide inside the slide grooves 205 to support the bottom of the front and rear sides of the cabin 8 to prevent the cabin 8 from tilting during testing.

[0024] The upper side wall of each first connecting rod 206 is fixedly connected to a first connecting column 208, the upper side wall of each first connecting column 208 is fixedly connected to a bottom cover 209, the interior of the upper side wall of each bottom cover 209 is fixedly connected to a first outer cylinder 210, the interior of each first outer cylinder 210 is slidably connected to a first inner rod 211, the top of each first inner rod 211 is fixedly connected to an upper cover 212, the interior of each bottom cover 209 and upper cover 212 is fixedly connected to a spring 213, the top of the spring 213 is fixedly connected to a second connecting column 214, the outer side of the top of each second connecting column 214 is threadedly connected to two nuts 215, and the four second connecting rods 214 are fixedly connected to each other. The top end of the column 214 passes through and is connected to the inside of the first support plate 203. Every two nuts 215 are set on the upper and lower sides of the first support plate 203 and are installed inside the bottom cover 209 and the upper cover 212 through the spring 213. The two nuts 215 threadedly connected to the outer side of the top end of the second connecting column 214 fix it to the first support plate 203. When the cabin 8 encounters bumps or is impacted by external force during the sliding process, the first inner rod 211 will slide in the first outer tube 210, compressing or stretching the spring 213. The elastic action of the spring 213 can absorb and buffer these impact forces, reduce damage to the cabin 8, and also ensure the stability of the cabin 8 during the sliding process.

[0025] like Figure 1 - Figure 7 As shown, first baffles 6 are fixedly connected to the interiors of the two left brackets 4, and second baffles 7 are fixedly connected to the interiors of the two right brackets 4. The first baffles 6 and second baffles 7 inside the four brackets 4 on the left and right sides completely block and partially block the left and right sides of the entire test bench to prevent parts from flying due to improper operation and excessive pressure when testing the cockpit 8. A reciprocating endurance fatigue testing mechanism 3 is set on the top of the top plate 5; The reciprocating endurance fatigue test mechanism 3 includes: a protection box 301, a motor 302, a second guide rail 306, a coupling block 309, a first device box 310, and a first hydraulic rod 311. The bottom wall of the protection box 301 is fixedly connected to the right side of the upper side wall of the top plate 5. The motor 302 is arranged inside the protection box 301. By fixing the protection box 301 to the right side of the upper side wall of the top plate 5, the motor 302 inside is protected from the outside. The output end of the motor 302 is fixedly connected to the rotating shaft 303, and the right end of the rotating shaft 303 is fixedly connected to the pulley 304. The belt 305 is arranged inside the pulley 304. When the motor 302 is started, the rotating shaft 303 on the output end of the motor 302 will drive the pulley 304 to rotate. By setting the belt 305 inside the pulley 304, the friction generated by the pulley 304 and the belt 305 drives the belt 305 to rotate inside the second guide rail 306.

[0026] The second guide rail 306 is set inside the two second baffles 7. The left side walls of the two second baffles 7 are fixedly connected to a connecting plate 10. The connecting plate 10 fixed to the left side wall of the second baffle 7 can support the third guide rail 11 on the left bottom wall on the one hand, and on the other hand, it can limit the first hydraulic rod 311 and other components to prevent excessive rising. The front side of the second guide rail 306 is provided with a first slider 307. The rear side wall of the first slider 307 is fixedly connected to four second pulleys 308. The four second pulleys 308 are slidably connected to the inside of the hole grooves on the left and right sides of the second guide rail 306. The second pulleys 308 on the rear side of the first slider 307 are set in the hole grooves on the left and right sides of the second guide rail 306, so that the first slider 307 is driven to slide up and down to provide a stable effect.

[0027] like Figure 1 - Figure 12 As shown, the bottom outer side of the belt 305 is set inside the second guide rail 306, and the coupling block 309 fixes the front part of the belt 305 to the inside of the first slider 307 through bolts. The front part of the belt 305 is fixed to the inside of the first slider 307 through the coupling block 309 and bolts, so that after the belt 305 is driven, it drives the first slider 307 to slide on the front side of the second guide rail 306.

[0028] The rear sidewall of the first device box 310 is fixedly connected to the front side of the first slider 307. The first device box 310 is fixed to the front side of the first slider 307 and moves with the slider. The outer side of the first hydraulic rod 311 is fixedly connected to the interior of the first device box 310. By fixing the first hydraulic rod 311 in the interior of the first device box 310, the outer side of the first hydraulic rod 311 is protected. The outer side of the telescopic end of the first hydraulic rod 311 is connected to the second support plate 312, and the second outer cylinder 313 is fixedly connected to the upper and lower sides of the interior of the first device box 310. The second inner rod 314 is slidably connected to the interior of the two second outer cylinders 313. The left ends of the two second inner rods 314 are fixedly connected to the upper and lower sides of the right side wall of the second support plate 312. The telescopic end of the first hydraulic rod 311 passes through the interior of the second support plate 312, so that the telescopic end of the first hydraulic rod 311 drives the second support plate 312 to move when it is telescoped, and the left end of the second inner rod 314 in the second outer cylinder 313 is connected to the right side wall of the second support plate 312, thereby providing a stable and balanced effect for the telescopic end of the first hydraulic rod 311.

[0029] The outer side of the telescopic end of the first hydraulic rod 311 is connected to an extension rod 315 by a thread. The length of the extension rod 315 connected by a thread on the outer side of the telescopic end of the first hydraulic rod 311 can be adjusted according to the test requirements. The left end of the extension rod 315 is fixedly connected to a sleeve 316, and the left side of the sleeve 316 is fixedly connected to a right clamping plate 317. A left clamping plate 318 is provided on the left side of the right clamping plate 317. The front and rear sides of the right clamping plate 317 and the left clamping plate 318 are both penetrated and connected by a second connecting rod 319. The left and right ends of each second connecting rod 319 are both threadedly connected to two fixing rings 320. Each of the two fixing rings 320 is provided on the right side of the right clamping plate 317 and the left side of the left clamping plate 318. 318 is set on the right side wall inside the chassis 9, and the right splint 317 is set on the right side wall of the chassis 9. The right splint 317 is connected by the sleeve 316 at the left end of the extension rod 315. The right splint 317 and the left splint 318 are fixed together by the second connecting rod 319 and the fixing ring 320. The left splint 318 is set on the right side wall inside the chassis 9, and the right splint 317 is set on the right side wall of the chassis 9, connecting the reciprocating endurance fatigue test mechanism 3 with the chassis 9 at the bottom of the cabin 8.

[0030] As shown above, during the durability test of the cabin 8, the sliding support mechanism 2 first stabilizes the cabin 8 on the test bench 1, allowing for adjustment as needed. The motor 302 of the reciprocating fatigue test mechanism 3 is then activated. This drives the pulley 304 and belt 305, causing the first slider 307 to slide back and forth on the second guide rail 306, adjusting the device to a height parallel to the cabin 8. The movement of the first slider 307 connects to the cabin 8 via the first hydraulic rod 311, extension rod 315, and right and left clamping plates 317 and 318, driving the cabin 8 in a reciprocating motion in the left and right directions. During this process, the sliding support mechanism 2 continuously provides stable support and cushioning for the cabin 8, ensuring a smooth test. This repeated left and right reciprocating motion simulates the frequent movement and vibration experienced in actual use, allowing for a comprehensive test and assessment of the cabin 8's structural strength and component durability.

[0031] like Figure 1 - Figure 16 As shown, the right side wall of the first baffle 6 and the left side wall of the connecting plate 10 are both fixedly connected to a third guide rail 11. The two third guide rails 11 are supported and fixedly connected by the right side wall of the first baffle 6 and the left side wall of the connecting plate 10. Second sliders 12 are slidably connected to the outer sides of the two third guide rails 11, and second limiting plates 13 are fixedly connected to the bottom walls of the two third guide rails 11. By fixing the two second limiting plates 13 to the bottom of the third guide rails 11, the second sliders 12 are prevented from sliding inside the third guide rails 11 and thereby limiting the position of the second sliders 12.

[0032] The outer side walls of the two second sliders 12 are fixedly connected to the load-bearing plate 14, and the upper side walls of the load-bearing plate 14 are fixedly connected to the second device box 17. A top box 15 is provided on the top of the top plate 5, and the interior of the top box 15 is fixedly connected to the second hydraulic rod 16. The telescopic end of the second hydraulic rod 16 passes through the interior of the second device box 17 and is fixedly connected to the upper side wall of the load-bearing plate 14. The top box 15 is used to protect the inside of the second hydraulic rod 16 on the outside. When the second hydraulic rod 16 is started, the telescopic end of the second hydraulic rod 16 passes through the interior of the second device box 17 and is connected to the load-bearing plate 14 to drive the load-bearing plate 14 to slide up and down. When the load-bearing plate 14 slides, the left and right sides of the load-bearing plate 14 are fixed on the outer side walls of the two second sliders 12. At the same time, the second slider 12 will also slide synchronously in the third guide rail 11 to provide a stable and balanced effect for the load-bearing plate 14.

[0033] Cylinders 18 are provided inside the second device box 17, and connecting pieces 19 are fixedly connected to the outside of the telescopic ends of the two cylinders 18. The second device box 17 is used to protect the outside of the internal cylinders 18, and the connecting pieces 19 on the telescopic ends of the cylinders 18 are fit together with the circular plate 20 on the top to connect with the circular plate 20.

[0034] like Figure 1 - Figure 16 As shown, the bottom of the telescopic end of the two cylinders 18 is fixedly connected to a circular plate 20, which is connected to an external air pump through the cylinder 18 to transfer gas to the inside of the cylinder 18. The cylinder 18 compresses the gas, causing the telescopic end of the cylinder 18 to quickly expand and contract, thereby driving the bottom circular plate 20 to slide up and down. The upper side walls of the circular plates 20 are fixedly connected to a plurality of support blocks 21, and the inner walls of each two support blocks 21 are fixedly connected to a third connecting rod 22. The outer side of each third connecting rod 22 is provided with a buckle 23. The support blocks 21 at the top of the circular plates 20 and the third connecting rod 22 act as a clamping ring, so that the buckle 23 is installed on the outer side of the third connecting rod 22, and is driven by the circular plate 20 to move up and down, and is supported by the third connecting rod 22 and the support blocks 21.

[0035] The bottom wall of each buckle 23 is fixedly connected to a connecting rope 24. The bottom wall of the circular plate 20 is provided with an impact sand bag 25. The bottoms of the four connecting ropes 24 are fixedly connected to the holes in the impact sand bag 25. The impact sand bag 25 is connected to the impact sand bag 25 through the connecting rope 24 at the bottom of the buckle 23. By filling the impact sand bag 25 with sand particles to a certain weight, when the cylinder 18 is telescopically extended, the impact sand bag 25 will move rapidly downward under the pull of the connecting rope 24, exerting a large impact force on the smart cockpit 8 below. When the cylinder 18 is telescopically retracted, the impact sand bag 25 will be pulled up again and return to its initial position. By repeating this process, multiple vertical impacts that the smart cockpit 8 may encounter in actual use can be simulated.

[0036] As shown above, during testing, the load-bearing plate 14 and impact sandbag 25 are first adjusted to the appropriate height according to the test requirements by controlling the extension and retraction of the second hydraulic rod 16. Then, the cylinder 18 is activated to cause it to extend and retract according to the preset frequency and stroke. The extension and retraction of the cylinder 18 drives the circular plate 20 up and down, and the impact sandbag 25 then impacts the cabin 8 in a regular manner via the connecting rope 24. During the impact process, the response of the cabin 8, such as deformation and stress distribution, can be recorded in real time by external monitoring and control equipment to assess the durability and reliability of the cabin 8. The entire device, through the coordinated height adjustment of the second hydraulic rod 16 and the impact action of the cylinder 18, provides a comprehensive and accurate vertical pressure and impact testing environment for the cabin 8.

[0037] It should be noted that the present invention is a new energy vehicle intelligent cockpit durability testing device. First, it is connected to an external power supply and a detection console through a motor 302, a first hydraulic rod 311, a second hydraulic rod 16, and a cylinder 18 to power the device, control the device, and view data.

[0038] The base 201 in the sliding support mechanism 2 is fixed to the middle of the upper side wall of the test bench 1, and the first guide rail 202 thereon is the basic track for the sliding of the cabin 8. The first support plate 203 is threadedly connected to the base frame 9 at the bottom of the cabin 8. When the cabin 8 needs to be moved, the eight first pulleys 204 on the left and right sides of the bottom of the first support plate 203 will roll in the hole grooves on the front and back sides of the first guide rail 202. The first limit plates 216 on the left and right sides of the first guide rail 202 serve to limit the lateral movement range of the first pulley 204, preventing the first pulley 204 from detaching from the guide rail, thereby ensuring the stability and safety of the cabin 8 during the sliding process. The sliding friction between the cabin 8 and the test bench 1 is converted into rolling friction, which greatly reduces the friction force, allowing the cabin 8 to move more easily and smoothly on the test bench 1, facilitating the simulation of usage in different positions.

[0039] The chutes 205 located on the front and rear sides of the base 201 of the test bench 1 provide additional support and guidance for the sliding of the cabin 8. Each chute 205 is equipped with two first connecting rods 206. Rotating wheels 207, rotatably connected to the front and rear ends of the first connecting rods 206, can roll freely within the chute 205. When the cabin 8 slides on the first guide rail 202, the rotating wheels 207 move within the chute 205 along with the first connecting rods 206, providing auxiliary support for the first support plate 203 and the cabin 8. This helps to share some of the weight of the cabin 8 and reduce the burden on the first guide rail 202 and the first pulley 204. This also further ensures the accuracy of the sliding direction of the cabin 8, preventing deviation or shaking.

[0040] The first connecting post 208, bottom cover 209, first outer tube 210, first inner rod 211, upper cover 212, spring 213, and second connecting post 214 on the first connecting rod 206 form an elastic buffer structure. The spring 213 is mounted inside the bottom cover 209 and upper cover 212. Two nuts 215 threaded onto the outer ends of the second connecting post 214 secure it to the first support plate 203. When the cabin 8 encounters bumps or external impacts during sliding, the first inner rod 211 slides within the first outer tube 210, compressing or stretching the spring 213. The elastic action of the spring 213 absorbs and cushions these impacts, minimizing damage to the cabin 8 while ensuring smooth sliding. Furthermore, by adjusting the position of the nut 215 on the second connecting post 214, the preload of the spring 213 can be varied, thereby adjusting the buffering effect according to different testing requirements.

[0041] After the motor 302 is started, its output end drives the rotating shaft 303 to rotate, and the pulley 304 at the right end of the rotating shaft 303 rotates accordingly. The pulley 304 transmits power through the belt 305. The bottom outer side of the belt 305 is set inside the second guide rail 306, and the front part of the belt 305 is fixedly connected to the first slider 307 through the joint block 309. In this way, the rotation of the motor 302 is converted into the movement of the belt 305, which in turn drives the first slider 307 to slide up and down on the second guide rail 306. The four second pulleys 308 on the rear side of the first slider 307 slide inside the holes on the left and right sides of the second guide rail 306, converting the sliding friction between the first slider 307 and the second guide rail 306 into rolling friction, reducing friction and allowing the first slider 307 to move more smoothly on the second guide rail 306. At the same time, the second guide rail 306 is fixed inside the two second baffles 7, ensuring the direction and stability of the slider's sliding.

[0042] The first device box 310 is fixed to the front of the first slider 307 and moves with the slider. A first hydraulic rod 311 is mounted inside the first device box 310, with its telescopic end extending through the second support plate 312. When the first hydraulic rod 311 extends or retracts, it moves the second support plate 312. Simultaneously, second inner rods 314 on the upper and lower sides of the second support plate 312 slide within the second outer cylinder 313, providing guidance and stability, ensuring smooth telescopic movement of the hydraulic rod.

[0043] The extension rod 315, which is threadedly connected to the outer side of the telescopic end of the first hydraulic rod 311, can adjust its length according to the test requirements. The sleeve 316 at the left end of the extension rod 315 is connected to the right clamping plate 317. The right clamping plate 317 and the left clamping plate 318 are fixed together by the second connecting rod 319 and the fixing ring 320. The left clamping plate 318 is set on the right side wall inside the chassis 9, and the right clamping plate 317 is set on the right side wall of the chassis 9. In this way, the reciprocating durability fatigue test mechanism 3 is connected to the chassis 9 of the cabin 8. When the first slider 307 slides back and forth on the second guide rail 306, it will drive the first hydraulic rod 311 and the clamping plate to move together, so that the cabin 8 reciprocates in the left and right directions, simulating the frequent movement and vibration in actual use, and performing a durability fatigue test on the cabin 8.

[0044] The right side wall of the first baffle 6 and the left side wall of the connecting plate 10 are both mounted with a third guide rail 11, providing guidance for the entire vertical motion structure. The second slider 12 can slide flexibly up and down on the outside of the third guide rail 11, ensuring the stability and accuracy of subsequent movement. The guide rail and slider are precisely matched, effectively reducing deviation and shaking during movement. A second limit plate 13 is fixed to the bottom wall of the third guide rail 11, whose main function is to limit the downward limit of the second slider 12. When the second slider 12 slides downward to a certain extent, it will contact the second limit plate 13, thereby preventing the slider from detaching from the guide rail, ensuring the safety and reliability of the entire device.

[0045] A second hydraulic rod 16 is installed within the top box 15 atop the top plate 5. It serves as the primary power source for raising and lowering the entire vertically moving assembly. The telescopic end of the second hydraulic rod 16 extends through the second device box 17 and is fixedly connected to the upper sidewall of the bearing plate 14. When the hydraulic system powers the second hydraulic rod 16, the telescopic end extends and retracts. Extending, it pushes the bearing plate 14 and its connected components downward; retracting, it pushes them upward. By precisely controlling the pressure and flow of the hydraulic system, the height and speed of the bearing plate 14 can be precisely adjusted to meet diverse testing requirements.

[0046] A connecting piece 19 is fixedly connected to the outside of the telescopic end of the cylinder 18, and a circular plate 20 is fixedly connected to the bottom. When compressed air is introduced into the air inlet of the cylinder 18, the telescopic end of the cylinder 18 will extend rapidly; when the air is discharged from the exhaust port, the telescopic end will retract. The rapid telescopic action can generate a large impact force.

[0047] The movement of the telescopic end of cylinder 18 is directly transmitted to circular plate 20. Multiple support blocks 21 are fixed to the upper sidewall of circular plate 20. The inner walls of every two support blocks 21 are connected by a third connecting rod 22. Each third connecting rod 22 is fitted with a buckle 23. These structures work together to form a stable connection system for securing a connecting rope 24. The bottom wall of buckle 23 is fixedly connected to the connecting rope 24, and the bottom of connecting rope 24 is fixed to the hole groove of impact sandbag 25. When the telescopic end of cylinder 18 drives circular plate 20 up and down, connecting rope 24 transmits this movement to impact sandbag 25. When the telescopic end of cylinder 18 is rapidly extended, impact sandbag 25, pulled by connecting rope 24, moves rapidly downward, exerting a large impact force on the smart cockpit 8 below. When the telescopic end of cylinder 18 is retracted, impact sandbag 25 is pulled up again, returning to its initial position. By repeating this process, multiple vertical impacts that the smart cockpit 8 may encounter in actual use can be simulated to test the structural strength and durability of the cockpit 8.
