[0002] At present, vehicle-mounted multimedia display screens are increasingly tending to be large-sized. Common vehicle-mounted multimedia display screens have two layout methods: horizontal screen and vertical screen. The layout method adopted is related to the interior styling of the vehicle. Currently, the vehicle-mounted display devices on large buses basically adopt an integral installation method. During installation, first, a fixing plate is fixed to the inner top of the large bus, and then the display screen is fixed to the fixing plate in a snap-fitting manner. When snap-fitting, the display screen needs to be lifted and aligned with the snap-fitting openings for snap-fitting, which greatly consumes the physical strength of workers. Or during installation, the decorative shell of the display screen is directly removed, and then the top structure of the display screen is integrally installed on the inner top of the large bus. These two types of assembly methods not only consume time, but also require professional technicians for assembly and disassembly. When the vehicle-mounted display device fails and needs to be replaced, it will cause great inconvenience. Moreover, for batch installation, the working hours are relatively long, which is not conducive to convenient assembly.

Detailed implementation mode

[0019] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to Figures 1 - 13 , the present invention proposes a vehicle-mounted display screen with convenient installation, including a folding display screen assembly 1, a main control module board 2, a clamping lock box body 3, and a mounting plate 4. The main control module board 2 is fixedly connected inside the folding display screen assembly 1. The main control module board 2 is a circuit board for controlling the folding display screen assembly 1 and the clamping lock box body 3. The clamping lock box body 3 is fixedly connected to the top of the folding display screen assembly 1. The mounting plate 4 is fixedly connected to the inner top of the vehicle by passing screws through the U-shaped hole 43 and locking them into the inner top wall of the vehicle. A step portion 41 is provided on the outer peripheral side of the mounting plate 4. A button 11 is provided on one side of the folding display screen assembly 1. The button 11, the folding display screen assembly 1, and the clamping lock box body 3 are all electrically connected to the main control module board 2. Pressing the button 11 can trigger the main control module board 2 to issue corresponding operation instructions to the clamping lock box body 3, so that the clamping lock box body 3 tightly clamps and fixes the step portion.

[0021] In this implementation mode, the clamping lock box body 3 is used as the external fixing component of the folding display screen assembly 1. By pressing the button 11 in an electric control manner, the clamping lock box body 3 is triggered to tightly clamp and fix the mounting plate 4. During installation, it is necessary to first install the mounting plate 4 on the inner top of the vehicle, then connect the vehicle power cord to the folding display screen assembly 1 to make the main control module board 2 powered on. Then, lift the folding display screen assembly 1 with both hands, align the top cover 32 at the top of the clamping lock box body 3 with the lower surface of the mounting plate 4 and form an elastic abutment. At this time, the outer peripheral side of the clamping lock box body 3 will be located on the outer peripheral side of the step portion 41. Then press the button 11, and at this time, the main control module board 2 can be triggered to issue corresponding locking operation instructions to the clamping lock box body 3, so that the clamping lock box body 3 tightly clamps and fixes the step portion 41. At this time, the installation of the folding display screen assembly 1 is completed, which is convenient and fast.

[0022] In this embodiment, the clamping lock box body 3 includes a fixing frame 31, a top cover 32, a first driving device 33, a transmission assembly 34, and a plurality of clamping lock assemblies 35. The first driving device 33 is a small reduction motor. Since the external clamping action of the clamping lock box body 3 is not very frequent, and at the same time, in order to reduce the overall weight of the clamping lock box body 3, the first driving device 33 can be driven without using a motor with a large torque. Therefore, the fixing frame 31, the top cover 32, the transmission assembly 34, and the clamping lock assemblies 35 are all made of engineering plastic materials. Compared with metals, engineering plastics are light in weight and have appropriate structural strength, and at the same time, the overall cost of the clamping lock box body 3 is reduced. This makes it convenient to be widely used on vehicle-mounted display screens. One end of the transmission assembly 34 passes through the fixing frame 31 and is rotatably connected to the fixing frame 31. The first driving device 33 is fixedly connected to one end of the fixing frame 31 and forms a transmission connection with one end of the transmission assembly 34. The other end of the transmission assembly 34 forms a transmission connection with one end of the plurality of clamping lock assemblies 35. The plurality of clamping lock assemblies 35 are all fixedly connected to the fixing frame 31 and are circumferentially evenly distributed around the transmission assembly 34. The top cover 32 is fixedly connected to the top of the fixing frame 31, and the top cover 32 elastically abuts against the lower surface of the mounting plate 4. The other end of the clamping lock assembly 35 extends to the outside of the fixing frame 31. Pressing the button 11 can trigger the main control module board 2 to issue a corresponding operation instruction to the first driving device 33. Thereby, the first driving device 33 rotates and drives the transmission assembly 34 to rotate, and then drives the plurality of clamping lock assemblies 35 to tightly clamp and fix the stepped portion 41 at the same time. The main control module board 2 is provided with a first driving module, a second driving module, a display module, and a data processing module. The data processing module is electrically connected to the first driving module, the second driving module, and the display module respectively. The data processing module is used to receive instructions from the button 11 or an external remote control and issue corresponding operation instructions to the first driving module, the second driving module, and the display module. The display module is electrically connected to the display 12 in the folding display screen assembly 1. The display module is used to issue a video playback instruction to the display 12. The second driving module is electrically connected to the second driving device 13 in the folding display screen assembly 1. The second driving module is used to issue a corresponding operation instruction to the second driving device 13. The second driving device 13 is used to drive the display 12 to flip open or fold and store. The first driving module is electrically connected to the first driving device 33. The first driving module is used to issue a corresponding operation instruction to the first driving device 33. The first driving device 33 is used to drive the transmission assembly 34 to rotate.

[0023] In this embodiment, when installing, it is necessary to first install the mounting plate 4 on the inner top of the vehicle, then connect the vehicle power cord to the folding display screen assembly 1 so that the main control module board 2 is powered on. Then, hold the folding display screen assembly 1 with both hands, align the top cover 32 of the top of the clamping lock box body 3 with the lower surface of the mounting plate 4 to form an elastic abutment. At this time, one end of the clamping lock assembly 35 will be located on one side of the stepped portion 41. Then, press the button 11. At this time, the main control module board 2 can be triggered to issue a corresponding locking operation instruction to the first driving device 33, so that the first driving device 33 rotates forward and drives the transmission assembly 34 to rotate counterclockwise, thereby driving a plurality of clamping lock assemblies 35 to tightly hold and clamp the stepped portion 41 at the same time. At this time, the installation of the folding display screen assembly 1 is completed, which is convenient and fast. If it is necessary to remove the folding display screen assembly 1 from the inner top of the vehicle, long-press the button 11 for 2 to 3 seconds. At this time, the main control module board 2 will recognize this long-press instruction, and then issue an unlocking operation instruction to the first driving device 33, so that the first driving device 33 rotates reversely and drives the transmission assembly 34 to rotate clockwise, thereby driving a plurality of clamping lock assemblies 35 to loosen the stepped portion 41 at the same time. At this time, the folding display screen assembly 1 can be removed from the inner top of the vehicle; In summary, the portable in-vehicle display screen of the present invention can effectively improve the convenience of installation, so as to quickly install the in-vehicle display screen time-saving and labor-saving.

[0024] In this embodiment, the clamping and locking assembly 35 includes a regional mounting frame 351, a screw rod 352, a balancing sliding block 353, and a clamping and locking plate 354. The regional mounting frame 351, the screw rod 352, the balancing sliding block 353, and the clamping and locking plate 354 are all made of engineering plastics. The regional mounting frame 351 is fixedly connected to one side of the fixed frame 31, the screw rod 352 is rotatably connected to the regional mounting frame 351, the balancing sliding block 353 is slidably connected to the regional mounting frame 351, one end of the screw rod 352 is connected to the transmission assembly 34, the balancing sliding block 353 is H-shaped, and the other end of the screw rod 352 passes through the middle of the balancing sliding block 353 and forms a screw transmission connection with the balancing sliding block 353. In this way, The locking plate 354 is a C-shaped structure, one end of the locking plate 354 is hinged to one end of the balancing sliding block 353, one side of the locking plate 354 is connected to one side of the area mounting frame 351 to form a slidable rotating connection, the locking plate 354 protrudes from the outside of the area mounting frame 351 and faces upward, and the C-shaped structure is conducive to the locking plate 354 to obtain a larger opening angle when opened, and can clamp the step portion 41 when clamping. When the transmission assembly 34 rotates counterclockwise, the transmission assembly 34 drives all the screw rods 352 to rotate forward, and when the screw rods 352 rotate forward, it will drive the balancing sliding block 353 to The locking plate 354 is swung into position to engage with the locking member 352, which in turn engages the locking member 353. The locking member 354 is then swung into position to engage the locking member 352, which in turn engages the locking member 353. One end is retracted inward, and since one side of the clamping plate 354 forms a slidable rotating connection with one side of the area mounting frame 351, the other end of the clamping plate 354 is tilted downward and rotated in the direction away from the step portion 41, so that the clamping plate 354 is opened to unlock the step portion 41; the number of clamping assemblies 35 depends on the geometric shape of the clamping box body 3, that is, depends on the geometric shape of the fixing frame 31, and also depends on the geometric shape of the mounting plate 4. If the fixing frame 31 is a quadrilateral, there are 4 clamping assemblies 35, and the mounting plate 4 also needs to be a quadrilateral structure. The 4 clamping assemblies 35 simultaneously hook the step portions 41 on the 4 sides of the mounting plate 4 to form a clamping and fixing.

[0025] In this embodiment, the transmission assembly 34 includes a crown gear member 341, a rotating rod 342, and a first transmission gear 343. The crown gear member 341, the rotating rod 342, and the first transmission gear 343 are all made of engineering plastics. The crown gear member 341 is coaxially and fixedly connected to one end of the rotating rod 342, and the first transmission gear 343 is coaxially and fixedly connected to the other end of the rotating rod 342. The rotating rod 342 passes through the fixing frame 31 and is rotatably connected to the fixing frame 31. One end of the lead screw member 352 is provided with a second transmission gear 3521. The crown gear member 341 is horizontally arranged and is simultaneously in transmission connection with a plurality of second transmission gears 3521. The rotating shaft of the first driving device 33 is provided with a third transmission gear 331, and the third transmission gear 331 is meshed and connected to the first transmission gear 343. When the first driving device 33 rotates forward, the third transmission gear 331 rotates forward and transmits power to the first transmission gear 343, causing the first transmission gear 343 to rotate in the reverse direction. Since the first transmission gear 343 is coaxially fixed to the crown gear member 341 through the rotating rod 342, the crown gear member 341 also rotates in the reverse direction, that is, it rotates counterclockwise at this time. The crown gear member 341 will drive the second transmission gears 3521 on all the lead screw members 352 to rotate forward. The pitch circle diameter of the first transmission gear 343 is a, the pitch circle diameter of the second transmission gear 3521 is b, the pitch circle diameter of the third transmission gear 331 is c, and the pitch circle diameter of the crown gear member 341 is d. 3c = a, b = c, and d = 1.5a.

[0026] In this embodiment, the clamping lock box body 3 further includes a number of limit blocks 36 equal to the number of the clamping lock assemblies 35. The limit blocks 36 are made of engineering plastics. A plurality of limit blocks 36 respectively correspond to a plurality of clamping lock assemblies 35 one by one. The limit blocks 36 are fixedly connected to the top of the area mounting frame 351 and extend to the top of the crown gear member 341. The limit blocks 36 form a sliding connection with the top of the crown gear member 341. The limit blocks 36 are used to provide a support structure for the meshing transmission between the crown gear member 341 and the second transmission gear 3521, ensuring that the crown gear member 341 does not slip during the meshing process.

[0027] In this embodiment, a connecting boss 3511 is provided on one side of the regional mounting bracket 351. Connecting columns 35111 are provided on both sides of the connecting boss 3511. Two connecting plates 3541 are provided on one side of the clamping lock plate 354. A strip-shaped groove 35411 is provided on the connecting plate 3541. The two connecting columns 35111 respectively penetrate through the strip-shaped groove 35411 and form a rotatable connection capable of sliding with the strip-shaped groove 35411. When the balance sliding block 353 slides in the direction towards the clamping lock plate 354, the balance sliding block 353 will push one end of the clamping lock plate 354. Since the two connecting columns 35111 respectively penetrate through the strip-shaped groove 35411 and form a rotatable connection capable of sliding with the strip-shaped groove 35411, that is, the outer peripheral side of the connecting column 35111 forms a sliding connection with the groove wall of the strip-shaped groove 35411. In this way, the connecting column 35111 serves as a fulcrum structure. When the clamping lock plate 354 is pried, since the connecting column 35111 is fixed, at this time, the strip-shaped groove 35411 will slide relative to the connecting column 35111. At the same time, during the sliding process, the connecting plate 3541 will rotate around the connecting column 35111 as the rotation center, so that the other end of the clamping lock plate 354 moves towards the step portion 41 for hook-up movement.

[0028] In this embodiment, two sliding support platforms 3512 are provided on the regional mounting bracket 351. The two sliding support platforms 3512 are symmetrically arranged along the lead screw member 352. A limiting channel 35121 is provided on the sliding support platform 3512. Two sliding rods 3531 are provided on the balance sliding block 353. The two sliding rods 3531 respectively penetrate through the two limiting channels 35121 and form a sliding connection with the two sliding support platforms 3512 respectively. The sliding support platform 3512 is used to provide a sliding support structure for the balance sliding block 353, and the limiting channel 35121 is used to provide a structure for the sliding rod 3531 to be inserted and slide, preventing the sliding support platform 3512 from detaching from the balance sliding block 353.

[0029] In this embodiment, a hook-up end 3542 is provided at one end of the clamping lock plate 354. A hook-up groove 411 is provided on the step portion 41. When the balance sliding block 353 pushes the bottom end of the clamping lock plate 354 to extend outwards, the hook-up end 3542 moves towards the hook-up groove 411. Finally, the hook-up end 3542 is received in the hook-up groove 411. The groove wall of the hook-up groove 411 can be an arc-shaped structure, so that the hook-up end 3542 can be stably hooked in the hook-up groove 411.

[0030] In this embodiment, a plurality of elastic pieces 321 are provided on the top cover 32. The plurality of elastic pieces 321 all protrude from the upper surface of the top cover 32. A alignment groove 42 is provided on the mounting plate 4. A part of the top cover 32 is received in the alignment groove 42, and the elastic piece 321 abuts against the groove wall of the alignment groove 42. The function of the alignment groove 42 is to facilitate quick positioning and installation by the worker when lifting the folding display screen assembly 1, and to provide a space for the clamping lock box body 3 to be positioned and inserted. In order to ensure that the clamping lock box body 3 does not loosen after the clamping lock assembly 35 clamps and fixes the stepped portion 41, a plurality of elastic pieces 321 are provided on the top cover 32. When the clamping lock assembly 35 clamps and fixes the stepped portion 41, the plurality of elastic pieces 321 abut against the groove wall of the alignment groove 42, and the abutting elastic force fills the gap between the clamping lock box body 3 and the alignment groove 42, making the vehicle-mounted display screen more stable.
