Description

Technical Field

[0001] This invention belongs to the field of promotion service technology, specifically relating to an efficient promotion and publicity device and method. Background Technology

[0002] Publicity and promotion are indispensable parts of business activities, public services, and cultural dissemination. Traditional publicity methods often rely on static posters or display boards. However, these conventional methods have significant limitations in practical application.

[0003] Existing promotional devices mostly consist of a display board within the device, displaying advertisements and other promotional activities. However, they can only display information on one side of the screen during a single promotional event, without the ability to switch between different displays, resulting in limited information presented. Therefore, providing an efficient promotional device and method is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The main objective of this invention is to provide an efficient promotion and publicity device and method to solve the aforementioned technical problems. The device includes a display component, a transmission component, and a pressing mechanism. The pressing mechanism works in conjunction with the transmission component to drive the display component in a cyclical display, thereby improving the publicity effect and achieving efficient promotion and publicity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An efficient promotional device includes an upper top plate, a lower bottom plate, display components, and a pressing mechanism. The upper top plate is provided with a guide groove, a mounting cavity, and a driving groove. The upper top plate is connected to a transmission component through the guide groove and the driving groove. The lower bottom plate has the same structure as the upper top plate and is also provided with a guide groove, a mounting cavity, and a driving groove. The lower bottom plate is connected to the transmission component through the guide groove and the driving groove. Multiple display components are connected between the upper top plate and the lower bottom plate through two vertically opposite guide grooves and two driving grooves. The pressing mechanism is also fixedly connected to the top of the lower bottom plate.

[0006] Furthermore, the transmission assembly includes a motor, a gear, a gear, and a double-sided toothed synchronous belt. The upper top plate also has a gear three mounting slot and multiple gear two mounting slots. Gear two is rotatably connected to each gear two mounting slot, and gear three is rotatably connected to each gear three mounting slot. The motor is housed within the mounting cavity, and its output end passes through the upper top plate and connects to the gear three. The gear three mounting slot communicates with one gear two mounting slot, and the gear two mounting slot communicates with a drive slot. Gear three meshes with one gear two, and gear two also meshes with the double-sided toothed synchronous belt located in the drive slot. Teeth are also provided on the inner wall of the drive slot on the side away from the double-sided toothed synchronous belt, and these teeth, along with the double-sided toothed synchronous belt, are connected to the display assembly.

[0007] Furthermore, a ramp groove is provided on the straight end of the guide groove. The ramp groove is inclined from the outside to the inside. The drive groove has a T-shaped structure. Two guide blocks are provided at the bottom end of the upper top plate near the ramp groove, and two guide blocks are provided at the top end of the lower bottom plate near the ramp groove.

[0008] Furthermore, the display assembly includes a guide rod, a guide plate, a transverse connecting rod, a support column, a display panel, a first connecting guide mechanism, and a second connecting guide mechanism. Two display panels are hinged together at one end. A guide plate is fixedly connected to one side of each display panel. The two display panels are connected to the guide rod through the two first connecting guide mechanisms. The two ends of the guide rod abut against guide grooves provided on the upper top plate and the lower bottom plate, respectively. Both display panels are connected to the support column through the second connecting guide mechanism. The two support columns are fixedly connected to each other through multiple transverse connecting rods. A gear is rotatably connected to both ends of each support column. The gear meshes with teeth and a double-sided synchronous belt provided in the drive groove.

[0009] Furthermore, the connecting guide mechanism includes a connector, a clamp, and an auxiliary connecting rod. The connector is fixed to the outer wall of the guide rod. The auxiliary connecting rod is rotatably connected to the end of the connector away from the outer wall of the guide rod. The clamp is rotatably connected to the end of the auxiliary connecting rod away from the guide rod. The clamp is slidably connected to the guide plate.

[0010] Furthermore, the second connecting guide mechanism includes a rotating component and a first locking component. The support column is provided with multiple locking slots. The support column is rotatably connected to the rotating component through the locking slots. The rotating component is rotatably connected to the first locking component, and the first locking component is slidably connected to the guide plate.

[0011] Furthermore, both ends of the guide rod are provided with extrusion grooves, and an extrusion column is provided in the extrusion groove. A retaining ring is fixedly provided on the extrusion column. A spring is sleeved on the part of the extrusion column located inside the retaining ring. One end of the spring is connected to the retaining ring, and the other end is connected to the inner wall of the extrusion groove.

[0012] Furthermore, the extrusion mechanism includes a fixed plate, a second transmission assembly, a rotating shaft, an extrusion plate, and a second motor. Two fixed plates are fixed to the top of the lower base plate, and a rotating shaft is rotatably connected between the two fixed plates. An extrusion plate is fixedly connected to the rotating shaft. One end of the rotating shaft passes through the fixed plate and is connected to the second transmission assembly. The top of the lower base plate is also fixedly connected to the second motor. The output end of the second motor passes through the fixed plate near the second transmission assembly and is fixedly connected to the second transmission assembly. The second transmission assembly includes an output transmission wheel, a driven transmission wheel, and a transmission belt. The output end of the second motor passes through the fixed plate and is connected to the output transmission wheel. The end of the rotating shaft near the second motor passes through the fixed plate and is connected to the driven transmission wheel. One end of the transmission belt is sleeved on the output transmission wheel, and the other end is sleeved on the driven transmission wheel.

[0013] Furthermore, the mounting cavity of the upper top plate is also equipped with an audio system, a PLC controller, and a power module. The audio system and the power module are electrically connected to the PLC controller. The PLC controller is also electrically connected to motor one in the upper top plate and motor two in the lower bottom plate. An infrared detector is installed on the lower bottom plate or the upper bottom plate, and the infrared detector is electrically connected to the PLC controller.

[0014] A promotional method for an efficient promotional device includes the following steps: Step 1: Install the corresponding display components between the top plate and the bottom plate; Step 2: Post promotional information on the display board of the display components; Step 3: Record the corresponding promotional advertisement into the speaker; Step 4: The PLC controller controls the motors on the top plate and bottom plate to run synchronously. Motor 1 drives gear 3 to rotate, gear 3 drives a single gear 2 to rotate, and with the cooperation of multiple other gears 2, drives the double-sided toothed synchronous belt to rotate around the drive groove. The double-sided toothed synchronous belt and the gears set on the inner wall of the drive groove cooperate to drive gear 1 connected to the display component to rotate. Gear 1 is rotatably connected to the support column. The rotation of gear 1 does not drive the support column to rotate, but instead moves the support column and the entire display component along the drive groove. Step 5: When the display component moves to the ramp of the guide groove under the control of the PLC controller, the PLC controller detects and confirms the signal emitted by the infrared detector, stops the operation of motor one, and starts motor two. Motor two drives the entire extrusion plate to rotate. The rotation of the extrusion plate pushes the guide rod into the ramp. At the same time, as the ramp compresses the extrusion column, the guide rod pushes the two hinged display panels to unfold when it enters the ramp, thereby achieving the advertising effect. At the same time, the PLC controller controls the sound system to play the advertising information on the two display panels. Step 6: After the display ends, start motor 2 to stop the extrusion plate. The extrusion column unfolds under the action of the spring, pushing the entire display panel to close. The entire guide rod returns to the guide groove. Then, start motor 1 through the PLC controller to drive the other two pairs of display components for display and promotion.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention includes a display component, a transmission component, and an extrusion mechanism. The extrusion mechanism works in conjunction with the transmission component to drive the display component to perform cyclical display, thereby improving the promotional effect and achieving efficient promotion. In addition, the display component in this invention can work with the sound system to control the sound to convey different information according to different display content. The advertising device in this invention is more effective than traditional paper advertising structures. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1-11 As shown, the present invention provides an efficient promotional device, including an upper top plate 1, a lower bottom plate 2, display components, and a pressing mechanism. The upper top plate 1 is provided with a guide groove 1.3, a mounting cavity 1.1, and a driving groove 1.2. The upper top plate 1 is connected to a transmission component 1 through the guide groove 1.3 and the driving groove 1.2. The lower bottom plate 2 has the same symmetrical design as the upper top plate 1. The lower bottom plate 2 is also provided with a guide groove 1.3, a mounting cavity 1.1, and a driving groove 1.2. The lower bottom plate 2 is connected to the transmission component 1 through the guide groove 1.3 and the driving groove 1.2. Multiple display components are connected between the upper top plate 1 and the lower bottom plate 2 through two vertically opposite guide grooves 1.3 and two driving grooves 1.2. The pressing mechanism is also fixedly connected to the top of the lower bottom plate 2.

[0031] In this embodiment, the transmission assembly includes a motor 6, a gear 27, a gear 3 28, and a double-sided toothed synchronous belt 26. The upper top plate 1 also has a gear 3 mounting slot and multiple gear 2 mounting slots. Gear 27 is rotatably connected to each gear 2 mounting slot, and gear 3 28 is rotatably connected to each gear 3 mounting slot. The motor 6 is housed in the mounting cavity 1.1. The output end of the motor 6 passes through the upper top plate 1 and connects to the gear 3 28. The gear 3 mounting slot communicates with one gear 2 mounting slot, and the gear 2 mounting slot communicates with the drive slot 1.2. Gear 3 28 meshes with one gear 2 27. Gear 2 27 is also connected to a gear located in the drive slot. The double-sided toothed synchronous belt 26 in drive groove 1.2 is engaged. A tooth 1.5 is also provided on the inner wall of the drive groove 1.2 on the side away from the double-sided toothed synchronous belt 26. The tooth 1.5 and the double-sided toothed synchronous belt 26 are also connected to the display component. Motor 1 6 can drive gear 3 28 to rotate. Since the double-sided toothed synchronous belt 26 is entirely fitted inside drive groove 1.2 and meshes with multiple gears 27, when gear 3 28 drives one gear 27 to rotate, it can drive the entire double-sided toothed synchronous belt 26 to rotate. When the double-sided toothed synchronous belt 26 rotates, it will drive gear 1 25 on the display component to rotate. Gear 1 25 will drive the entire display component to move along drive groove 1.2.

[0032] In this embodiment, a ramp groove 1.4 is also provided on the straight end of the guide groove 1.3. The ramp groove 1.4 is inclined from the outside to the inside. The drive groove 1.2 has a T-shaped structure. Two guide blocks 7 are provided at the bottom end of the upper top plate 1 near the ramp groove 1.4. Two guide blocks 7 are provided at the top end of the lower bottom plate 2 near the ramp groove 1.4. The ramp groove 1.4 can cooperate with the guide rod 19 to realize the opening and closing of the display plate 14. The guide blocks 7 are used to guide the guide rod 19.

[0033] In this embodiment, the display assembly includes a guide rod 19, a guide plate 18, a transverse connecting rod 15, a support column 13, a display panel 14, a first connecting guide mechanism, and a second connecting guide mechanism. Two display panels 14 are hinged together at one end. A guide plate 18 is fixedly connected to one side of each display panel 14. The two display panels 14 are connected to the guide rod 19 via two first connecting guide mechanisms. The two ends of the guide rod 19 abut against guide grooves 1.3 on the upper top plate 1 and lower bottom plate 2, respectively. Both display panels 14 are connected to support columns 13 via the second connecting guide mechanism. The two support columns 13 are fixedly connected by multiple transverse connecting rods 15. Gears 25 are rotatably connected to both ends of each support column 13. Gears 25 mesh with teeth 1.5 and a double-sided synchronous belt 26 located in the drive groove 1.2. When the guide rod 19 moves, it pushes the two display panels 14 to unfold via the first connecting guide mechanism, thus displaying information on the display panels 14.

[0034] In this embodiment, the first connecting guide mechanism includes a connector 20, a second clamp 21, and an auxiliary connecting rod 22. The connector 20 is fixed on the outer wall of the guide rod 19. The auxiliary connecting rod 22 is rotatably connected to the end of the connector 20 away from the outer wall of the guide rod 19. The second clamp 21 is rotatably connected to the end of the auxiliary connecting rod 22 away from the guide rod 19. The second clamp 21 is slidably connected to the guide plate 18.

[0035] In this embodiment, the second connecting guide mechanism includes a rotating component 16 and a first locking component 17. The support column 13 is provided with multiple locking slots 13.1. The support column 13 is rotatably connected to the rotating component 16 through the locking slots 13.1. The rotating component 16 is rotatably connected to the first locking component 17, and the first locking component 17 is slidably connected to the guide plate 18. The first locking component 17 and the second locking component 21 are both slidably connected to the guide plate 18. At the same time, in conjunction with the rotating component 16, the connecting component 20, and the auxiliary connecting rod 22, the mutually hinged display panel 14 can be unfolded without affecting the movement or orientation change of the display panel 14.

[0036] In this embodiment, both ends of the guide rod 19 are provided with extrusion grooves 19.1, and an extrusion column 24 is provided in the extrusion groove 19.1. A retaining ring 24.1 is fixedly provided on the extrusion column 24. A spring 23 is sleeved on the part of the extrusion column 24 located inside the retaining ring 24.1. One end of the spring 23 is connected to the retaining ring 24.1, and the other end is connected to the inner wall of the extrusion groove 19.1. When the guide rod 19 is pushed into the inclined groove 1.4, the upper and lower inclined grooves 1.4 simultaneously extrude the two extrusion columns 24. The extrusion column 24 extrudes the spring 23 through the retaining ring 24.1. When the thrust on the guide rod 19 disappears, the extrusion column 24 unfolds along the slope towards the guide groove 1.3 under the extrusion of the spring 23, thereby pulling the guide rod 19 to reset.

[0037] In this embodiment, the extrusion mechanism includes a fixed plate 9, a transmission assembly 10, a rotating shaft 11, an extrusion plate 12, and a motor 8. The two fixed plates 9 are fixed to the top of the lower base plate 2, and the rotating shaft 11 is rotatably connected between the two fixed plates 9. The extrusion plate 12 is fixedly connected to the rotating shaft 11. One end of the rotating shaft 11 passes through the fixed plate 9 and is connected to the transmission assembly 10. The top of the lower base plate 2 is also fixedly connected to the motor 8. The output end of the motor 8 passes through the fixed plate 9 near the transmission assembly 10 and is fixedly connected to the transmission assembly 10. A bearing is also provided at the connection between the rotating shaft 11 and the fixed plate 9. The transmission assembly 10 includes an output transmission wheel, a driven transmission wheel, and a transmission belt. The output end of the motor 8 passes through the fixed plate 9 and is connected to the output transmission wheel. The end of the rotating shaft 11 near the motor 8 passes through the fixed plate 9 and is connected to the driven transmission wheel. One end of the transmission belt is sleeved on the output transmission wheel, and the other end is sleeved on the driven transmission wheel. The motor 8 can drive the output transmission wheel to rotate, and the output transmission wheel can drive the driven transmission wheel to rotate through the transmission belt. The driven transmission wheel can drive the extrusion plate 12 and the rotating shaft 11 to rotate.

[0038] In this embodiment, an audio speaker 3, a PLC controller 4, and a power module 5 are also provided in the mounting cavity 1.1 of the upper top plate 1. The audio speaker 3 and the power module 5 are electrically connected to the PLC controller 4. The PLC controller 4 is also electrically connected to motor 6 in the upper top plate 1 and the lower bottom plate 2, respectively. The PLC controller 4 is also electrically connected to motor 8. An infrared detector is installed on the lower bottom plate 2 or the upper bottom plate 1. The infrared detector is electrically connected to the PLC controller 4. The infrared detector is located between the guide blocks 7 and is installed on the lower bottom plate 2 or the upper top plate 1 on the inner side of the guide groove 1.3. It is used to determine the specific position of the guide rod 19.

[0039] A promotional method for an efficient promotional device includes the following steps: Step 1: Install multiple display components between the upper top plate 1 and the lower bottom plate 2. Step 2: Post promotional information on the display board 14 of the display components; Step 3: Record the corresponding promotional advertisement in speaker 3; Step 4: PLC controller 4 controls motor 6 on the upper top plate 1 and lower bottom plate 2 to run synchronously. Motor 6 drives gear 3 28 to rotate. Gear 3 28 drives a single gear 27 to rotate. With the cooperation of multiple other gears 27, it drives the double-sided toothed synchronous belt 26 to rotate around the drive groove 1.2. The double-sided toothed synchronous belt 26 and the gears set on the inner wall of the drive groove 1.2 drive the gear 25 connected to the display component to rotate. Gear 25 is rotatably connected to the support column 13. The rotation of gear 25 does not drive the support column 13 to rotate, but instead moves the support column 13 and the entire display component along the drive groove 1.2. Step 5: When the display component moves to the ramp 1.4 of the guide groove 1.3 under the control of the PLC controller 4, the PLC controller 4 detects and confirms the signal emitted by the infrared detector, stops the operation of motor 6, and starts motor 8. Motor 8 drives the entire extrusion plate 12 to rotate. The rotation of the extrusion plate 12 pushes the guide rod 19 into the ramp 1.4. At the same time, as the ramp 1.4 compresses the extrusion column 24, the guide rod 19 pushes the two hinged display plates 14 to unfold when it enters the ramp 1.4, thereby achieving the advertising effect. At the same time, the PLC controller 4 controls the sound system to play the advertising information on the two display plates 14. Step 6: After the display ends, start motor 28 to stop the extrusion of extrusion plate 12. Extrusion column 24 unfolds under the action of spring 23, pushing the entire display panel 14 to close. The entire guide rod 19 returns to the guide groove 1.3. PLC controller 4 starts motor 16 to drive the other two pairs of display components for display and promotion.

The PLC controller (4) is also electrically connected to motor one (6) in the upper top plate (1) and the lower bottom plate (2) respectively. The PLC controller (4) is also electrically connected to motor two (8). An infrared detector is installed on the lower bottom plate (2) or the upper bottom plate (1). The infrared detector is electrically connected to the PLC controller (4).

10. A promotional method for an efficient promotional device, implemented using the promotional device described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Install multiple display components between the top plate (1) and the bottom plate (2); Step 2: Post the information that needs to be promoted on the display board (14) of the display components; Step 3: Enter the corresponding promotional advertisement into the audio (3); Step 4, the PLC controller (4) controls the motor 1 (6) on the top plate (1) and the bottom plate (2) to run synchronously. The motor 1 (6) drives the gear 3 (28) to rotate. The gear 3 (28) drives a single gear 2 (27) to rotate. With the cooperation of multiple other gears 2 (27), the double-sided toothed synchronous belt (26) rotates around the drive groove (1.2). The double-sided toothed synchronous belt (26) and the gears set on the inner wall of the drive groove (1.2) drive the gear 1 (25) connected to the display component to rotate. The gear 1 (25) is rotatably connected to the support column (13). The rotation of the gear 1 (25) will not drive the support column (13) to rotate, but will move the support column (13) and the entire display component along the drive groove (1.2). Step 5: When the display component moves to the ramp (1.4) of the guide groove (1.3) under the control of the PLC controller (4), the PLC controller (4) detects and confirms the signal emitted by the infrared detector, stops the operation of motor one (6), and starts motor two (8). Motor two (8) drives the entire extrusion plate (12) to rotate. The rotation of the extrusion plate (12) pushes the guide rod (19) into the ramp (1.4). At the same time, as the ramp (1.4) compresses the extrusion column (24), the guide rod (19) pushes the two hinged display plates (14) to unfold when it enters the ramp (1.4), thereby achieving the publicity effect. At the same time, the PLC controller (4) controls the sound system to play the publicity information on the two display plates (14). Step 6: After the display is completed, start motor 2 (8) to stop the extrusion of the extrusion plate (12). The extrusion column (24) unfolds under the action of spring (23), pushing the entire display plate (14) to close. The entire guide rod (19) returns to the guide groove (1.3). The PLC controller (4) starts motor 1 (6) to drive the other two pairs of display components to carry out the display and promotion.
