Description

Technical Field

[0001] The present invention relates to the technical field of display cabins, and particularly to an enterprise interactive digital linkage display cabin. Background Art

[0002] A display cabin is a cabin body composed of multiple display screens with display functions. It has good interactivity in enterprise promotion and can help enterprises more intuitively and accurately display products. Currently, most display cabins are of fixed design, which is inconvenient for mobile display. Moreover, multiple display screens in the display cabin always remain in the unfolded state, occupying a large space when idle, and the unfolded display screens are more likely to be contaminated with dust and damaged by external forces. In addition, in order to improve the display effect of the display cabin, large-sized display screens are generally selected, and large-sized display screens have the problem of difficult cleaning. Therefore, an enterprise interactive digital linkage display cabin is proposed, which can fold and clean the display screens when idle. Summary of the Invention

[0040] Referring to Figures 1 - 15 , an enterprise interactive digital linkage display cabin includes a main screen 2 fixedly installed on a trolley 1. Sub-screens 3 are hinged on both sides of the main screen 2. Hinge columns 4 are fixedly installed on the left and right sides of the main screen 2, and hinge rods 5 are rotatably installed on the two hinge columns 4. Two hinge blocks 6 are fixedly installed on the side walls of one ends of the two sub-screens 3 close to the main screen 2. The two hinge rods 5 are respectively fixedly connected to the corresponding two hinge blocks 6, and the two hinge rods 5 are both rotatably connected to the trolley 1. Through the cooperation of the hinge rod 5 and the hinge block 6, the installation angles of the two sub-screens 3 relative to the main screen 2 can be adjusted. When the display cabin is not needed, the two sub-screens 3 can be rotated towards the main screen 2 at the same time, and a triangle is formed between the two sub-screens 3 and the main screen 2. At this time, the fronts (liquid crystal surfaces) of the main screen 2 and the two sub-screens 3 face the inside, which can effectively reduce the possibility of dust adhering to their fronts, and at the same time protect the fronts, avoiding the problem of damage to the liquid crystal surface caused by external forces. For the convenience of description, hereinafter, the main screen 2 and the two sub-screens 3 are collectively referred to as the "display screen".

[0041] It also includes a folding component which is used to reversely and synchronously adjust the installation angles of the two secondary screens 3 on both sides of the main screen 2. The folding component includes three folding shafts 11 rotatably installed in the trolley 1, and a belt drive structure 12 is installed between the three folding shafts 11. The belt drive structure 12 is a prior art, and its working principle and specific structure will not be elaborated here. Through the design of the belt drive structure 12, the three folding shafts 11 can rotate in the same direction simultaneously. A connecting shaft is rotatably installed in the trolley 1. Fixed gears 13 are fixedly installed at the bottoms of both hinge rods 5. Connecting gears 14 are fixedly installed at the bottoms of the connecting shaft and the two folding shafts 11 away from the drive shaft 41. The two connecting gears 14 on the connecting shaft and the corresponding folding shafts 11 are meshed with each other. The connecting gears 14 at the bottoms of the two folding shafts 11 are respectively meshed with the two fixed gears 13. Refer to Figure 2 and Figure 15 , when the folding shaft 11 close to the drive shaft 41 rotates clockwise, the left folding shaft 11 can rotate counterclockwise simultaneously under the meshing effect of the corresponding connecting gear 14 and the fixed gear 13. And under the meshing effect of the right fixed gear 13 and the corresponding two connecting gears 14, the right folding shaft 11 rotates clockwise simultaneously. At this time, the two secondary screens 3 rotate towards the liquid crystal surface of the main screen 2 at the same time, realizing the folding action. On the contrary, when the folding shaft 11 close to the drive shaft 41 rotates counterclockwise, the two secondary screens 3 can be unfolded.

[0042] A backboard 7 is fixedly installed on the trolley 1, and a push handle is fixedly installed on the backboard 7. A plurality of universal wheels 8 are installed at the bottom of the trolley 1. The design of the push handle facilitates the pushing of the trolley 1. The universal wheels 8 can make the turning action of the trolley 1 more flexible. At the same time, self-locking components are provided on the universal wheels 8. The self-locking components are existing products, and their working principle and specific structure will not be elaborated here. The self-locking components can fix the position of the trolley 1 after it is moved in place. Fixed guide posts 9 are fixedly installed at the bottoms of the two secondary screens 3. Arc-shaped grooves 10 matching with the two guide posts 9 are opened on the trolley 1. The cooperation between the guide posts 9 and the arc-shaped grooves 10 is used to limit the moving direction of the secondary screens 3 on the trolley 1.

[0043] The dust cleaning part is used to clean the main screen 2 and the two secondary screens 3 simultaneously after the two secondary screens 3 are folded. The dust cleaning part includes a mounting seat 17 rotatably mounted on the cart 1 through a rotating shaft 16. An installation block 18 is mounted on the mounting seat 17 through a swinging assembly. The swinging assembly consists of a support block, a lead screw 33, an arc rod 34, a lifting rack 35, and a swinging gear 36. A groove is formed in the mounting seat 17. A round rod is fixedly mounted on the side wall of the installation block 18, and the round rod is rotatably connected to the mounting seat 17. The support block is fixedly mounted on the side wall of the mounting seat 17. The lead screw 33 is rotatably mounted on the mounting seat 17. The arc rod 34 is threadedly mounted on the lead screw 33, and the arc rod 34 is slidably engaged with the mounting seat 17 up and down. The lifting rack 35 is fixedly mounted on the arc rod 34. The swinging gear 36 is fixedly mounted on the end of the round rod outside the mounting seat 17, and the swinging gear 36 is engaged with the lifting rack 35. As Figure 7 shown, when the lead screw 33 rotates to drive the lifting rack 35 to move downward, the engagement effect between the lifting rack 35 and the swinging gear 36 can make the round rod drive the installation block 18 to rotate and stand up on the mounting seat 17. Conversely, when the installation block 18 has stood up on the cart 1, rotating the lead screw 33 to drive the lifting rack 35 to move upward can make the installation block 18 rotate to be horizontal with the cart 1.

[0044] An installation rod 19 is fixedly mounted on the installation block 18. A plurality of arc plates 20 are mounted on the installation rod 19 through a telescopic assembly. The telescopic assembly is used to synchronously adjust the distance between the plurality of arc plates 20 and the installation rod 19. The telescopic assembly consists of a moving groove 21, a bidirectional lead screw 22, two moving blocks 23, a plurality of connecting rods 24, a plurality of through grooves 26, and multiple groups of fixing blocks 25. The moving groove 21 is formed in the installation rod 19. The bidirectional lead screw 22 is rotatably mounted inside the installation rod 19. The two moving blocks 23 are threadedly connected to one end of the bidirectional lead screw 22 located in the moving groove 21. A plurality of connecting rods 24 are swingably mounted on the two moving blocks 23. A plurality of through grooves 26 are formed in the side wall of the moving groove 21, and each through groove 26 is respectively matched with the corresponding connecting rod 24. Two groups of fixing blocks 25 are fixedly mounted on the inner wall of each arc plate 20, and a swinging shaft fixedly connected to the corresponding connecting rod 24 is rotatably mounted between each group of fixing blocks 25. Each group of fixing blocks 25 consists of two fixing blocks 25. When the bidirectional lead screw 22 rotates, it can drive the two moving blocks 23 to move away from or close to each other. When the two moving blocks 23 move away from each other, the plurality of connecting rods 24 are lifted, and at this time, the plurality of arc plates 20 automatically unfold. Conversely, when the two moving blocks 23 move close to each other, the plurality of arc plates 20 automatically contract towards the installation rod 19.

[0045] A control component matched with the telescopic component is installed between the mounting seat 17 and the mounting block 18. The control component is used to control the operation of the telescopic component according to the angle of the mounting block 18 on the mounting seat 17. The control component consists of a circular shaft 37, an active bevel gear 38, a driven bevel gear, a transmission ring gear 39 and a fixed gear rod 40. The circular shaft 37 is rotatably mounted on the mounting block 18. The active bevel gear 38 and the transmission ring gear 39 are both fixedly mounted on the circular shaft 37. The driven bevel gear is fixedly mounted on one end of the bidirectional lead screw 22 located in the mounting block 18, and the driven bevel gear is meshed with the active bevel gear 38. The fixed gear rod 40 is fixedly mounted in the groove. The fixed gear rod 40 is meshed with the transmission gear ring 39. When the mounting block 18 is rotated and erected on the mounting seat 17, the transmission gear ring 39 drives the circular shaft 37 to rotate due to the meshing effect of the fixed gear rod 40 and the rotation effect of the mounting block 18, and then the two-way lead screw 22 is rotated forward through the meshing effect of the active bevel gear 38 and the driven bevel gear. The forward rotation of the two-way lead screw 22 causes the two moving blocks 23 to move away from each other, thereby realizing the automatic deployment of the multiple arc plates 20. Conversely, when the mounting block 18 is rotated to a horizontal state on the mounting seat 17, the two-way lead screw 22 will reverse. At this time, the two moving blocks 23 approach each other to complete the folding of the multiple arc plates 20.

[0046] A plurality of arc strips 31 are swingably mounted on each arc plate 20, a plurality of cleaning bristles 32 are fixedly mounted on each arc strip 31, a swing block is fixedly mounted on the side wall of the arc strip 31, a swing groove matching the swing block is provided on the side wall of the arc plate 20, and a swing rod rotatably connected to the swing block is fixedly mounted in the swing groove, a torsion spring coaxial with the swing rod is installed between the swing block and the swing groove, the elastic force of the torsion spring can keep the arc strip 31 vertical on the arc plate 20 when the swing block is not subjected to external force, at this time, the plurality of cleaning bristles 32 are in an expanded state on the arc plate 20, which greatly improves the cleaning range and can effectively clean the liquid crystal surface of the display screen, and in order to further improve the cleaning effect of the cleaning bristles 32, the positions of the arc strips 31 on the plurality of arc plates 20 can be staggered with each other, and the cleaning bristles 32 can be made of a soft material, such as microfiber.

[0047] Connecting rods 28 are slidably mounted at both ends of each curved plate 20, and a plurality of pressure strips 30 are fixedly mounted between each two corresponding connecting rods 28 at the front and rear positions, each pressure strip 30 is matched with a corresponding curved strip 31, and the pressure strip 30 is used to adjust the angle of the curved strip 31 on the curved plate 20, such as Figure 7As shown, when each arc plate 20 is close to the mounting rod 19, the plurality of pressure strips 30 are outside the plurality of arc strips 31. At this time, the squeezing effect of the pressure strip 30 on the arc strip 31 makes it remain level with the arc plate 20, so the plurality of cleaning bristles 32 are in a state of being folded on the arc plate 20. When the pressure strip 30 moves to the right and separates from the arc strip 31, the elastic force of the torsion spring can make the arc strip 31 drive the cleaning bristles 32 to be in an expanded state on the arc plate 20.

[0048] Each arc plate 20 is provided with a sliding mechanism matched with a corresponding connecting rod 28, and the sliding mechanism is composed of a side gear 27, a fixed rack 29, two sliders and two slide grooves. The side gear 27 is fixedly mounted on a swing shaft away from the mounting block 18, the fixed rack 29 is fixedly mounted on one of the connecting rods 28, and the fixed rack 29 is meshed with the side gear 27, the two sliders are respectively fixedly mounted on the two connecting rods 28, and the two slide grooves are respectively provided on the front and rear side walls of the arc plate 20, and the two slide grooves are respectively connected to the two slider slides. When the arc plate 20 moves away from the mounting rod 19 under the action of the telescopic assembly, the connecting rod 24 drives the side gear 27 to rotate clockwise. At this time, the meshing effect of the side gear 27 and the fixed rack 29 allows the connecting rod 28 to drive the multiple pressure strips 30 to move to the right at the same time. After that, the squeezing effect of the multiple arc strips 31 disappears, and the cleaning bristles 32 can be automatically unfolded on the arc plate 20. Cooperating with the unfolding action of the arc plate 20, the subsequent cleaning range can be greatly improved, ensuring that the folded display screen can be effectively cleaned.

[0049] The transmission part includes a driving shaft 41 rotatably installed in the trolley 1. The transmission part is used to make the installation rod 19 swing to be perpendicular to the trolley 1 before the two auxiliary screens 3 are folded, and to clean the main screen 2 and the auxiliary screen 3 after the two auxiliary screens 3 are folded. A driving ring gear 42 and a fixed ring gear 46 are fixedly installed on the driving shaft 41. A positioning gear 45 is fixedly installed at the bottom of the folding shaft 11 close to the driving shaft 41. A rotating rod 43 is rotatably installed in the trolley 1, and a transmission gear 44 is fixedly installed at the bottom of the rotating rod 43. The transmission gear 44 and the positioning gear 45 are both matched with the driving ring gear 42. The trolley 1 is provided with a storage groove 15 matched with the installation rod 19 and a plurality of arc-shaped plates 20. A docking seat 49 is fixedly installed at one end of the rotating rod 43 located in the storage groove 15, and a docking block 48 matched with the docking seat 49 is fixedly installed at the bottom of the screw rod 33. Figure 1 as well as Figure 15 When the display cabin is used normally, the display screen is in the unfolded state, the mounting rod 19 and the plurality of arc-shaped plates 20 are stored in the storage groove 15, and the position states of the driving gear ring 42, the alignment gear 45 and the transmission gear 44 are also as shown. Figure 15As shown, when the display screen needs to be folded, the drive shaft 41 is rotated counterclockwise by one circle. During this process, the drive gear ring 42 first drives the transmission gear 44 to rotate clockwise. The rotating rod 43 makes the lead screw 33 rotate clockwise simultaneously through the cooperation of the docking seat 49 and the docking block 48. At this time, the lifting rack 35 moves downward, causing the mounting block 18 to rotate towards the vertical state on the mounting seat 17. During the process of the mounting block 18 rotating towards the vertical direction, the cooperation between the control component and the telescopic component causes the plurality of arc-shaped plates 20 to automatically unfold outward, and at the same time that the arc-shaped plates 20 unfold outward, the plurality of arc-shaped strips 31 automatically unfold;

[0050] When the engagement between the drive gear ring 42 and the transmission gear 44 ends, the mounting rod 19 is in a completely vertical state, and the arc-shaped plate 20 and the cleaning brush bristles 32 thereon are both in a fully unfolded state. The drive gear ring 42 continues to rotate and meshes with the alignment gear 45. At this time, the alignment gear 45 drives the folding shaft 11 to rotate clockwise, thereby automatically completing the folding action of the display screen;

[0051] The alignment gear ring 47 is fixedly installed on the rotating shaft 16, and the alignment gear ring 47 cooperates with the fixed gear ring 46. Both the drive gear ring 42 and the fixed gear ring 46 are incomplete gear rings, and the toothed part of the drive gear ring 42 corresponds to the toothless part of the fixed gear ring 46 in terms of angle. Through the design of this angle, when the drive gear ring 42 disengages from the transmission gear 44 (i.e., when the mounting rod 19 is in a completely vertical state), the alignment gear ring 47 meshes with the alignment gear ring 47. At this time, the continuous rotation of the drive shaft 41 will drive the mounting rod 19 to rotate horizontally on the cart 1 through the mounting seat 17, and this rotation will continue until the drive shaft 41 stops rotating, and with reference to Figure 15The positional relationship between the middle transmission gear 44 and the alignment gear 45. When the driving gear ring 42 meshes and disengages with the alignment gear 45 (i.e., when the display screen has been folded), the fixed gear ring 46 remains in a meshing state with the alignment gear ring 47. Then, the rotation of the drive shaft 41 at this time can cause the mounting rod 19 to drive the cleaning brush bristles 32 to effectively clean the liquid crystal surface of the display screen. The toothed part on the driving gear ring 42 is an integer multiple of the circumference of the transmission gear 44. The purpose of this dimension design is to make the number of rotations of the rotating rod 43 an integer each time it is driven by the drive shaft 41, so as to ensure the connection angle between the docking seat 49 and the docking block 48, and avoid the problem of movement interference between the docking block 48 and the docking seat 49 when the mounting seat 17 rotates later to drive the lead screw 33 to rotate horizontally.
