Description

Technical Field

[0001] This invention relates to the field of aging detection devices, and more particularly to an aging detection device for vehicle screens with safety protection functions. Background Technology

[0002] As a crucial component of automotive electronic equipment, the lifespan and stability of in-vehicle displays directly impact driving experience and safety. Therefore, rigorous aging tests are necessary before the screen leaves the factory. Existing in-vehicle display aging testing devices exhibit the following problems during use:

[0003] 1. Poor adaptability: The clamping structure of the existing device has a fixed size, which cannot flexibly adapt to different specifications and sizes of vehicle screens. As a result, one testing device can only be used to test a single model of vehicle screen, which increases testing costs and reduces testing efficiency.

[0004] 2. Inconvenient material handling: After the vehicle screen is tested, the testing personnel need to manually reach into the testing chamber to pick it up. The operating space is limited, and the surface of the vehicle screen is smooth, making it easy to slip and cause damage. At the same time, the loosening and locking of the clamping structure is cumbersome, which further affects the convenience of material handling.

[0005] 3. Insufficient safety protection: Under aging testing environments such as high temperature and high pressure, vehicle screens may crack. Existing devices lack effective protective structures, and the resulting fragments can easily fly, threatening the personal safety of testing personnel. Furthermore, the scattered fragments increase the difficulty of subsequent cleanup. Therefore, this solution proposes a vehicle screen aging testing device with safety protection functions. Summary of the Invention

[0006] The present invention proposes an aging detection device for vehicle screens with safety protection function, which solves the problems of low adaptability and lack of protection function in the existing aging detection devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A vehicle-mounted screen aging detection device with safety protection function includes an aging chamber and multiple partitions installed sequentially from top to bottom inside the aging chamber. The device is characterized in that multiple placement slots are formed on the top surface of each partition, and a loading unit for placing the vehicle-mounted screen is movably installed within each slot. The loading unit includes:

[0009] A placement plate that slides into a placement slot and is used to place the vehicle screen;

[0010] A clamping mechanism is mounted on a placement plate and used to position and clamp the vehicle screen. The clamping mechanism includes two movable plates that slide on the top surface of the placement plate, a clamping plate mounted on the outer wall of the movable plate near the center of the placement plate, and a transmission component mounted on the bottom surface of the placement plate to drive the two clamping plates to move closer to each other when the placement plate moves out of the placement slot and when the placement plate moves inward into the placement slot. An adjustment component is mounted on the movable plate to adjust the distance between it and the clamping plate.

[0011] A protective mechanism is used to cover the outside of the clamping mechanism to protect the vehicle screen from shattering. The protective mechanism includes two protective covers symmetrically mounted on the top surface of the placement plate and a drive assembly mounted on the placement plate for driving the two protective covers to open and close. The drive assembly cooperates with the transmission assembly to open the two protective covers when the two clamping plates are far apart and close them when the two clamping plates are close together.

[0012] A material support mechanism, which is mounted on a placement plate and used to lift one end of the vehicle screen placed on its top surface upward when the placement plate is pulled outward.

[0013] The above technical solution can not only automatically position and clamp the vehicle screen when the placement plate is pushed into the placement slot, but also automatically release the vehicle screen when the placement plate is pulled out, while also having good protective performance.

[0014] As a further improvement to the above solution, the two long sides of the placement groove are provided with sliding grooves along their length direction, and the two long sides of the placement plate are fixed with sliders along their length direction, one side of the sliders extending into the sliding grooves and slidingly engaging with them.

[0015] As a further improvement to the above solution, the movable plate has an insertion hole on the side facing the clamping plate. The adjustment assembly includes a fixed rod that is movably inserted into the insertion hole and a locking bolt that is threaded to the top surface of the movable plate. One end of the fixed rod is fixed to the outer wall of the clamping plate, and one end of the locking bolt abuts against the top surface of the fixed rod.

[0016] As a further improvement to the above solution, the transmission assembly includes a bidirectional screw rotatably connected to its bottom along the width direction of the placement plate and two moving blocks respectively threaded onto the opposite portions of the two threads outside the bidirectional screw. Both sides of the top surface of the placement plate are provided with connecting grooves arranged along its width direction. The two moving blocks pass through the two connecting grooves and are fixed to the bottom of the two moving plates. A side rod is fixed to the outer periphery of the bidirectional screw along its radial direction. A buffer groove that cooperates with the side rod is provided at the bottom of the placement groove. The bottom of the side rod extends into the buffer groove. After the side rod abuts against the side of the buffer groove, it drives the side rod to rotate when the placement plate continues to move, thereby driving the bidirectional screw to rotate synchronously.

[0017] As a further improvement to the above solution, the top surface of the placement plate is rotatably connected to two mounting shafts arranged along its length. The bottom of one side of the two protective covers is fixed to the outer periphery of the two mounting shafts respectively. The two connecting grooves are provided with mounting grooves arranged along their length on the side that is far apart from each other. The drive assembly is provided in two sets, and the two sets of drive assemblies are respectively installed in the two mounting grooves and used to drive the mounting shafts to rotate when the moving block moves.

[0018] As a further improvement to the above solution, the drive assembly includes a drive gear rotatably connected in the mounting groove, a driven gear sleeved on the outer periphery of the mounting shaft, and a transmission rack located below and meshing with the drive gear. One end of the transmission rack extends into the connecting groove and is fixedly connected to the moving block. The driven gear is located on top of the drive gear and meshes with it.

[0019] The above technical solution enables the protective cover to rotate synchronously while the clamping plate moves, thereby achieving the purpose of automatically opening and closing the protective cover during the movement of the placement plate.

[0020] As a further improvement to the above solution, the top surface of the placement plate is provided with a storage groove for installing a lifting mechanism. The lifting mechanism includes a lifting plate disposed in the storage groove and a linkage component disposed in the storage groove. The end of the lifting plate away from the inner side of the placement groove is rotatably connected to the inner wall of the long side of the storage groove on both sides. The linkage component is connected to the bottom surface of the lifting plate near the inner side of the placement groove, and drives the end of the lifting plate near the inner side of the placement groove to rotate upward and lift when the placement plate is pulled out of the placement groove.

[0021] The above technical solution utilizes a lifting mechanism to lift one end of the vehicle-mounted screen upwards when the placement plate is pulled out, making it easier for testing personnel to pick it up.

[0022] As a further improvement to the above solution, the linkage component includes a sleeve rod fixed inside the storage slot along its length, a sliding sleeve movably sleeved on the outer periphery of the sleeve rod, a connecting rod hinged to the top surface of the sliding sleeve, and a fixing block fixed to the bottom surface of the sliding sleeve. The other end of the connecting rod is hinged to the bottom surface of the lifting plate. The bottom surface of the storage slot has a fixing groove arranged along its length. The bottom of the fixing block passes through the fixing groove and extends into the placement slot. A limiting block is detachably fixed on the bottom of the placement slot near its outer side. The fixing block and the limiting block cooperate to restrict the fixing block from moving out of the placement slot during the process of the placement plate continuing to be pulled out after the fixing block and the limiting block abut against each other.

[0023] As a further improvement to the above solution, a return spring is movably sleeved on the outer periphery of the sleeve rod. One end of the return spring is fixedly connected to the sliding sleeve, and the other end of the return spring is fixedly connected to the inner wall of the storage groove near the inner side of the placement groove. The width of the sliding sleeve is greater than the width of the fixed groove, and the bottom surface of the sliding sleeve slides against the bottom surface of the storage groove.

[0024] As a further improvement to the above solution, a support plate is fixed on the side of the top surface of the lifting plate away from the inner side of the placement groove, which is arranged along the width direction of the lifting plate.

[0025] Through the above technical solution, the support plate can block the edge of the vehicle screen, preventing the vehicle screen from slipping off the lifting plate during the lifting process.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By setting up the placement plate and clamping mechanism, the two moving plates in the clamping mechanism can be automatically driven to move away from each other during the process of pulling the placement plate outward, thereby releasing the vehicle screen clamped by the two clamping plates, making it easy for the inspection personnel to pick it up directly. When the placement plate is pushed into the placement slot, the two moving plates can also be automatically driven to move closer to each other, thereby allowing the clamping plates to center and clamp the vehicle screen, thus achieving the purpose of conveniently clamping and releasing the display screen.

[0028] 2. The adjustment mechanism allows for adjustment of the distance between the clamping plate and the moving plate, thereby adapting to and fixing vehicle screens of different sizes and improving the adaptability of the device.

[0029] 3. The protective mechanism can be installed outside the clamping mechanism during the testing process, so that the vehicle screen is also located inside the protective cover, effectively preventing fragments from flying around when the vehicle screen explodes. At the same time, in conjunction with the drive component, the protective cover is automatically opened when the placement plate is pulled outward, and automatically closed when the placement plate is pushed into the placement slot, further reducing the operation difficulty for testing personnel.

[0030] 4. The material support mechanism can lift one end of the lifting plate upward after the placement plate is pulled outward, thereby lifting the vehicle screen ladder section placed on the placement plate upward. After the placement plate is pushed into the placement slot, the lifting plate can be automatically lowered, which further facilitates the inspection personnel to pick up and put down the display screen on the placement plate.

[0042] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0043] Example 1:

[0044] Please combine Figure 1 - Figure 9 This embodiment of a vehicle screen aging test device with safety protection function includes an aging chamber 1 and multiple partitions 2 installed from top to bottom inside the aging chamber 1. Multiple placement slots 7 are opened on the top surface of the partitions 2. A loading part for placing the vehicle screen is movably installed in the placement slot 7. A door is installed on the front of the aging chamber 1. During the aging test, the vehicle screen to be tested is placed on the loading part, and then the door is closed to start the aging test.

[0045] The cargo compartment includes:

[0046] The placement plate 3 is slidably connected in the placement groove 7 and used to place the vehicle screen. The two long sides of the placement groove 7 are provided with sliding grooves along their length. The two long sides of the placement plate 3 are fixed with sliders 8 along their length. One side of the slider 8 extends into the sliding groove and slides with it. A pull ring 6 is installed on the outside of the placement plate 3. The pull ring 6 is designed to facilitate pulling the placement plate 3 out of the placement groove 7 when taking out or placing the vehicle screen.

[0047] A clamping mechanism, mounted on the placement plate 3, is used to position and clamp the vehicle screen. The clamping mechanism includes two movable plates 12 slidably connected to the top surface of the placement plate 3, a clamping plate 11 mounted on the outer wall of the movable plate 12 near the center of the placement plate 3, and a transmission assembly mounted on the bottom surface of the placement plate 3 to drive the two clamping plates 11 closer together when the placement plate 3 moves outwards into the placement groove 7, and to drive the two clamping plates 11 closer together when the placement plate 3 moves inwards into the placement groove 7. The transmission assembly includes a bidirectional screw 21 rotatably connected to the bottom of the placement plate 3 along its width direction, and two movable blocks 19 respectively threaded onto the opposite portions of the two threads on the outside of the bidirectional screw 21. Connecting grooves 18 are provided on both sides of the top surface of the placement plate 3 along its width direction. The two movable blocks 19 pass through the two connecting grooves 18 and are fixed to the bottom of the two movable plates 12. A side rod 26 is fixed to the outer periphery of the bidirectional screw 21 along its radial direction. A buffer groove 22 that mates with the side rod 26 is provided at the bottom of the placement groove 7. The bottom of the side rod 26 extends into the buffer groove 22, and after the side rod 26 abuts against the side of the buffer groove 22, it drives the side rod 26 to rotate as the placement plate 3 continues to move, thereby driving the bidirectional screw 21 to rotate synchronously. When the placement plate 3 is pulled outward, the side rod 26 moves within the buffer groove 22 and abuts against the side of the buffer groove 22. As the placement plate 3 continues to be pulled out, the side rod 26 drives the bidirectional screw 21 to rotate. Since the threads at both ends of the bidirectional screw 21 are opposite, the two moving blocks 19 drive the moving plate 12 to move away from each other, and the clamping plate... 11. Release the vehicle screen; during the process of pushing the placement plate 3 inward, after the side rod 26 and the end of the buffer groove 22 near the inner side of the placement groove 7 abut against each other, the side rod 26 will be driven to rotate in the opposite direction during the process of pushing the placement plate 3 inward. The bidirectional screw 21 drives the moving plate 12 to move closer to each other, and the clamping plate 11 clamps the vehicle screen in the center, thereby achieving the purpose of automatically releasing the clamped vehicle screen during the process of pulling out the placement plate 3, and automatically centering and clamping the vehicle screen during the process of pushing the placement plate 3 into the placement groove 7.

[0048] An adjustment assembly for adjusting the distance between the movable plate 12 and the clamping plate 11 is installed on the movable plate 12. An insertion hole is provided on the side of the movable plate 12 facing the clamping plate 11. The adjustment assembly includes a fixing rod 14 movably inserted into the insertion hole and a locking bolt threaded onto the top surface of the movable plate 12. One end of the fixing rod 14 is fixedly connected to the outer wall of the clamping plate 11, and one end of the locking bolt 12 abuts against the top surface of the fixing rod 14. The adjustment assembly allows for easy adjustment of the position of the clamping plate 11 according to the size of the vehicle screen. Since the movable plate 12 moves a fixed distance, when the vehicle screen is large, the distance between the clamping plate 11 and the movable plate 12 can be reduced. To adjust the distance between the clamping plates 11 and 12, loosen the locking bolts and move the clamping plate 11 closer to the moving plate 12. After adjustment, tighten the locking bolts again and lock the fixing rod 14 using the static friction between the locking bolts and the fixing rod 14. Then, operate the other clamping plate 11 in the same way. When the vehicle screen is small, increase the distance between the clamping plate 11 and the moving plate 12. Similarly, loosen the locking bolts first, then move the clamping plate 11 away from the moving plate 12. After adjustment, tighten the locking bolts again. This effectively enhances the adaptability of the device.

[0049] A protective mechanism, used to cover the clamping mechanism to protect the vehicle screen from shattering, includes two protective covers 4 symmetrically mounted on the top surface of the placement plate 3 and a drive assembly mounted on the placement plate 3 to drive the two protective covers 4 to open and close. The drive assembly cooperates with the transmission assembly to open the two protective covers 4 when the two clamping plates 11 move away from each other and close them when they move closer together. Mounting shafts 13, arranged along their length, are rotatably connected to both sides of the top surface of the placement plate 3. The bottom of one side of each of the two protective covers 4 is fixed to the outer periphery of the two mounting shafts 13. Mounting grooves 20, arranged along their length, are provided on the opposite sides of the two connecting grooves 18. Two sets of drive assemblies are provided, each set installed in one of the two mounting grooves 20 and used to drive the mounting shafts 13 to rotate when the moving block 19 moves. The drive assembly includes a drive gear 16 rotatably connected in the mounting groove 20 and a driven gear sleeved on the outer periphery of the mounting shaft 13. The gear 15 and the transmission rack 17 located below and meshing with the drive gear 16 have one end extending into the connecting groove 18 and fixed to the moving block 19. The driven gear 15 is located on top of the drive gear 16 and meshes with it. After the two protective covers 4 are closed, they cover the clamping mechanism and the outside of the vehicle screen, thus preventing fragments from flying around when the vehicle screen accidentally explodes. When the placement plate 3 is pulled outward, the two moving blocks 19 drive the two moving plates 12 to move away from each other. At this time, the transmission rack 17 moves synchronously with the moving plates 12, thereby driving the drive gear 16 to rotate forward. The forward rotation of the drive gear 16 drives the driven gear 15 to rotate in reverse, thereby driving the protective cover 4 to open through the mounting shaft 13. Conversely, when the placement plate 3 is pushed into the placement groove 7, the two moving plates 12 move closer to each other, and the clamping plate 11 gradually clamps the vehicle screen. The transmission rack 17 then drives the drive gear 16 to rotate, so that the protective cover 4 automatically and synchronously closes and covers the outside of the vehicle screen.

[0050] Example 2:

[0051] Combination Figure 3 , Figure 4 and Figure 6 - Figure 9This embodiment, based on embodiment 1, further improves upon the following: it also includes a material support mechanism, which is installed on the placement plate 3 and used to lift one end of the vehicle screen placed on its top surface upward when the placement plate 3 is pulled outward. The top surface of the placement plate 3 has a storage groove 29 for installing the lifting mechanism. The lifting mechanism includes a lifting plate 9 disposed within the storage groove 29 and a linkage component installed within the storage groove 29. One end of the lifting plate 9 away from the inner side of the placement groove 7 is rotatably connected to the inner walls of the long sides of the storage groove 29. The linkage component is connected to the bottom surface of the lifting plate 9 near the inner side of the placement groove 7. The side connection is provided, and when the placement plate 3 is pulled out of the placement slot 7, the lifting plate 9 is driven to rotate upward at one end near the inner side of the placement slot 7. A support plate 10 is fixed on the top surface of the lifting plate 9 away from the inner side of the placement slot 7, which is arranged along the width direction of the lifting plate 9. The support plate 10 can prevent the vehicle screen from sliding off the lifting plate 9 when one end of the lifting plate 9 is lifted. When the end of the lifting plate 9 near the inner side of the placement slot 7 is lifted upward, the vehicle screen placed on the placement plate 3 can be lifted, which makes it convenient for the inspection personnel to pick it up and place the vehicle screen on the placement plate 3.

[0052] The linkage assembly includes a sleeve rod 24 fixed inside the storage slot 29 along its length, a sliding sleeve 23 movably sleeved around the sleeve rod 24, a connecting rod 27 hinged to the top surface of the sliding sleeve 23, and a fixing block 25 fixed to the bottom surface of the sliding sleeve 23. The other end of the connecting rod 27 is hinged to the bottom surface of the lifting plate 9. The bottom surface of the storage slot 29 has a fixing groove 28 arranged along its length. The bottom of the fixing block 25 passes through the fixing groove 28 and extends into the placement slot 7. A limiting block 5 is detachably fixed on the bottom of the placement slot 7 near its outer side. The limiting block 5 is connected to the bottom of the placement slot 7 by screws. The fixing block 25 cooperates with the limiting block 5 to restrict the fixing block 25 from moving out of the placement slot 7 during the process of the placement plate 3 being pulled outward after the fixing block 25 abuts against the limiting block 5. When placing the vehicle screen, during the process of pulling out the placement plate 3 outward, when the fixing block 25 moves... When the device moves to contact the limiting block 5, the placement plate 3 continues to be pulled out. The fixing block 25 is blocked by the limiting block 5 and cannot move outward. The sliding sleeve 23 slides inward on the sleeve rod 24. The sliding sleeve 23 pushes the end of the lifting plate 9 near the inner side of the placement slot 7 to rotate upward and lift it through the connecting rod 27. The vehicle screen tilts with the lifting plate 9, making it convenient for the inspection personnel to place it. After placement, the placement plate 3 is pushed in, and the fixing block 25 is released from the limitation of the limiting block 5. Under the action of gravity, the sliding sleeve 23 slides outward to reset, and the lifting plate 9 returns to a horizontal state. The vehicle screen is placed stably on the placement plate 3. When the vehicle screen is taken out, the placement plate 3 is pulled outward. After the fixing block 25 contacts the limiting block 5, the lifting plate 9 automatically lifts up, and the vehicle screen tilts. The inspection personnel can easily grab the edge of the screen and take it out. After taking it out, the placement plate 3 is pushed in, and the lifting plate 9 automatically retracts into the storage slot 29.

[0053] A return spring is movably fitted around the outer periphery of the sleeve rod 24. One end of the return spring is fixedly connected to the sliding sleeve 23, and the other end of the return spring is fixedly connected to the inner wall of the storage groove 29 near the inner side of the placement groove 7. The width of the sliding sleeve 23 is greater than the width of the fixed groove 28, and the bottom surface of the sliding sleeve 23 slides against the bottom surface of the storage groove 29. When one end of the lifting plate 9 is lifted, the return spring is compressed by the sliding sleeve 23. When the vehicle screen is placed and the placement plate 3 moves into the placement groove 7, the return spring can drive the sliding sleeve 23 to move automatically away from the inner side of the placement groove 7, thereby achieving the purpose of automatically leveling the lifting plate 9 and preventing the sliding sleeve 23 from being stuck.

[0054] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
