Description

Technical Field

[0001] The invention belongs to the technical field of billboards, and in particular relates to a multifunctional billboard for advertising media. Background Art

[0002] Existing billboards only serve the purpose of promoting advertisements during use, by continuously playing advertising videos and pictures. However, the billboards themselves do not take external environmental factors into consideration during use. In particular, dust may accumulate on the protective glass outside the display screen during use of outdoor billboards, resulting in unclear display of the entire billboard and affecting the promotional effect. At the same time, outdoor billboards cannot protect the screen position in some bad weather, which accelerates the damage to the protective glass outside the screen, resulting in unclear display and other situations. Subsequent operations such as replacing the glass require a lot of time and energy. Summary of the Invention

[0006] Through the above technical solution, when in use, the picture data is displayed on the display screen through the display output component to realize advertising. At the same time, different advertising data can be stored through the data storage component for cyclic playback. The entire billboard can be remotely controlled through the wireless control component.

[0007] Furthermore, the protective driving mechanism includes two support bearing vertical plates fixedly connected between the top of the support base plate and the two sides of the inner wall of the support shell, and the first rotating rod and the second rotating rod are rotatably connected between the top and bottom of the two support bearing vertical plates, and the two ends of the first rotating rod and the second rotating rod are fixedly connected to the transmission sprocket, and multiple transmission sprockets are installed with a transmission chain between the two ends of the first rotating rod and the second rotating rod, and the two transmission chains are fixedly connected to the transmission bar on the side close to each other, and the front end of the transmission bar is fixedly connected to the limiting connecting block, and one side of the inner wall of the support shell is fixedly connected to the first motor base, the top of the first motor base is fixedly connected to the first driving motor, and the output end of the first driving motor is fixedly connected to the transmission sprocket on the top side, and the top and bottom of the two limiting connecting blocks are fixedly connected to the inner wall of the side limiting bar.

[0008] Through the above technical solution, the first drive motor drives the corresponding transmission sprocket and the first rotating rod to rotate between the two supporting bearing vertical plates, and realizes transmission through multiple transmission sprockets and two transmission chains, so that the two transmission chains start to drive the two limiting connecting blocks to move downward at the same time. At the same time, the top folding plastic plate of the limiting connecting block opens, and the bottom folding plastic plate folds and contracts, always maintaining a sealed state to prevent external dust from entering, and then drive the protective storage mechanism to achieve the driving function of protection and cleaning.

[0009] Furthermore, both sides of the front end of the support shell are provided with strip-shaped through holes corresponding to the limiting connection blocks.

[0010] Through the above technical solution, it is ensured that the internal drive can be transmitted to the external protective storage mechanism through the two limiting connecting blocks, and at the same time, the strip-shaped through hole also realizes the limiting sliding of the limiting connecting block.

[0011] Furthermore, the protective storage mechanism includes a mechanism protective shell fixedly connected to the top front end of the supporting shell, both sides of the mechanism protective shell are fixedly connected with side vertical plates, both sides of the rear end of the inner wall of the mechanism protective shell are fixedly connected with bearing plates, a winding rod is provided between the two bearing plates, the outer wall of the winding rod is wound with a protective cloth, and both ends of the outer wall of the winding rod and the corresponding side vertical plates are fixedly connected with a coil spring, the other end of the protective cloth is fixedly connected with a sliding fixing strip, the bottom of the sliding fixing strip is fixedly connected with a triangular fitting strip, and the inner side of the sliding fixing strip is fixedly connected with a cleaning sponge pad, a hard sponge pad and a drying sponge pad from bottom to top.

[0012] Through the above technical solution, in the process of the two limiting connecting blocks driving the sliding fixed bar to slowly descend, the cleaning sponge pad that absorbs detergent first starts to wipe the protective glass, soaks the dust with detergent, and then continuously scrapes off the dust with the hard sponge pad to achieve cleaning until it reaches the bottom, and then the first drive motor starts to drive the first rotating rod to reverse, and the sliding fixed bar is reset through the two transmission chains. In the process of the sliding fixed bar moving upward, the dry sponge pad starts to wipe the protective glass and absorbs the residual detergent. After complete reset, a clean protective glass is left. At the same time, in bad weather, the billboard is remotely controlled by the wireless control component. Similarly, the first drive motor starts to drive the corresponding transmission sprocket and The first rotating rod rotates between the two supporting bearing vertical plates to drive the two limit connecting blocks. During the descending process of the limit connecting block, the sliding fixed bar will be driven to descend, and then the protective cloth rolled up on the winding rod will be pulled. The rotation of the winding rod will compress the coil springs at both ends until the sliding fixed bar reaches the bottom. The triangular fitting strip at the bottom of the sliding fixed bar fits with the inclined surface at the top of the bottom fitting plate, which can achieve a good sealing effect. The protective cloth completely covers the protective glass and plays a protective role for the protective glass. When it is released later, the first driving motor starts to drive the first rotating rod to reverse, driving the sliding fixed bar to rise. At the same time, under the action of the two coil springs, it will actively drive the winding rod to reel in the protective cloth until it is fully reset.

[0013] Furthermore, the sliding fixing strip is fixedly connected between the two limiting connecting blocks.

[0014] The above technical solution ensures that the sliding fixing bar can be driven up and down by the two limiting connecting blocks.

[0015] Furthermore, the pre-cleaning spray mechanism includes a mechanism support shell fixedly connected to the front end of the top inner wall of the support shell, bearing blocks are fixedly connected on both sides of the inner wall of the mechanism support shell, a ball screw is arranged between the two bearing blocks, one side of the top of the inner wall of the support shell is fixedly connected to the second motor base, the top of the second motor base is fixedly connected to the second driving motor, and the output end of the second driving motor is fixedly connected to one end of the ball screw, a ball transmission sleeve is provided on the ball screw, the front end of the ball transmission sleeve is fixedly connected to the limiting plate, a spray head is installed at the center of the limiting plate, the rear end of the spray head is fixedly connected to a spray pipe, one end of the spray pipe is provided with a micro pump at the top of the support shell, the input end of the micro pump is provided with a liquid storage tank at the top of the support shell, the top of the liquid storage tank is fixedly connected with a threaded liquid filling port, and the threaded liquid filling port The outer wall of the opening is spirally connected to a threaded sleeve, and the bottom of the front end surface of the liquid storage tank is fixedly connected to the pump body protective shell, and one side of the liquid storage tank is fixedly connected to a transparent strip shell, and a scale is provided on the transparent strip shell, and the front and rear end surfaces of one side of the inner wall of the liquid storage tank are respectively installed with a liquid level control sensor and a solenoid valve, and a tap water access pipe is installed on one side of the rear end surface of the liquid storage tank, and the inner wall of the liquid storage tank is fixedly connected to a support sleeve shell, one end of the inner wall of the support sleeve shell is fixedly connected to an extrusion spring, and the other end of the extrusion spring is fixedly connected to an extrusion block, and multiple solid cleaning agents are placed on the inner wall of the support sleeve shell, and the rear end of the bottom of the support sleeve shell is fixedly connected to an extension limit shell, and the inner wall of the extension limit shell is slidably connected to a sliding rod, and the bottom of the sliding rod is fixedly connected to a float, and one side of the bottom inner surface of the liquid storage tank is fixedly connected to a bottom pad corresponding to the float.

[0016] Through the above technical solution, during the use of the billboard, a cleaning cycle is set. During the operation of the billboard, external dust will continuously accumulate on the outer surface of the protective glass. After the set cycle is reached, the pre-cleaning spray mechanism starts to work, wherein the micro pump starts to extract the washing liquid in the liquid storage tank, and then enters the nozzle through the spray pipe, and starts to spray the cleaning sponge pad part, so that the cleaning sponge pad absorbs the washing liquid inside, and the second drive motor starts to drive the ball screw to rotate between the two bearing blocks, thereby driving the ball transmission sleeve to move, and under the sliding limit of the limit plate, the ball transmission sleeve and the limit plate drive the nozzle horizontally, and then start to spray the entire cleaning sponge pad. After reaching the other end, the second drive motor drives the ball screw to reverse, realizing the reverse movement and reset of the ball transmission sleeve, thereby realizing two sprayings. After resetting, the micro pump stops working, thereby completing the spraying of the cleaning sponge pad, improving the subsequent cleaning effect, and the remaining washing liquid in the liquid storage tank can be clearly observed through the transparent strip shell, and then the threaded sleeve can be opened. Liquid is added through the threaded liquid filling port. Later, when the cleaning liquid inside the liquid storage tank is about to be exhausted, the liquid level control sensor senses that the cleaning liquid has reached the lowest liquid level, and then controls the solenoid valve to open. The tap water pipe connected to the tap water inlet pipe begins to flush tap water into the liquid storage tank. Then the liquid level control sensor detects that the liquid level has reached the set value and controls the solenoid valve to close. In this process, as the liquid level rises, the float will be pushed up, and then the sliding rod will be pushed to slide on the inner wall of the extension limit shell until the solid cleaning agent at the top is pushed out from the top opening at one end of the support sleeve, and then falls into the liquid storage tank and dissolves, starting to turn tap water into cleaning liquid, thereby realizing automatic addition of cleaning liquid. Multiple solid cleaning agents are always in an extruded state under the elastic force of the extrusion spring. Subsequent addition of solid cleaning agents can be done by pushing the extrusion block to compress the extrusion spring and adding solid cleaning agents one by one from the through hole at the top end of the support sleeve. The bottom pad can support the float when the liquid level is low to prevent the sliding rod from escaping the limit of the extension limit shell.

[0017] Furthermore, a strip-shaped through hole corresponding to the limiting plate is opened on the top of the front end of the support shell.

[0018] The above technical solution ensures that the limiting plate can drive the nozzle to slide in the strip-shaped through hole, thereby achieving spraying while also playing the role of sliding limitation.

[0019] Furthermore, the rear-end storage mechanism includes an embedded fixed shell fixedly connected to the rear end of the supporting shell, the inner wall of the embedded fixed shell is fixedly connected with multiple center partitions, the rear end of the inner wall of the embedded fixed shell is slidably connected to two sliding door panels, and the rear end faces of the two sliding door panels are fixedly connected with a clamping block on the side away from each other, and the two sliding door panels are fixedly connected with a sealing strip on the side close to each other.

[0020] Through the above technical solution, the embedded fixed shell utilizes the space inside the supporting shell, and then items can be stored on multiple central partitions in the embedded fixed shell, such as replaceable cleaning sponge pads and detergent, which are convenient for subsequent use. Sealing is achieved through two sliding door panels, and locking is achieved through blocks and snap lock bodies. Two sealing strips can seal the gap between the two sliding door panels to prevent dust from entering.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention designs a protective driving mechanism and a pre-cleaning spraying mechanism. During the use of the billboard, a cleaning cycle is set. After the set cycle is reached, the pre-cleaning spraying mechanism starts to work, wherein the micro pump starts to extract the washing liquid in the liquid storage tank, and then enters the nozzle through the spray pipe, and starts to spray the cleaning sponge pad part, so that the cleaning sponge pad absorbs the washing liquid inside, and the second driving motor starts to drive the ball screw to rotate between the two bearing blocks, and the ball transmission sleeve and the limit plate drive the nozzle to move horizontally, and then start to spray the entire cleaning sponge pad. A driving motor drives the corresponding transmission sprocket and the first rotating rod to rotate between the two supporting bearing vertical plates, so that the two transmission chains start to drive the two limit connecting blocks to move downward at the same time. In the process of the sliding fixed bar slowly descending, the cleaning sponge pad adsorbing detergent first starts to wipe the protective glass, soaking the dust with detergent, and then continuously scraping the dust off with the hard sponge pad to achieve cleaning until it reaches the bottom. Then the first driving motor starts to drive the first rotating rod to reverse, and in the process of the sliding fixed bar upward, the dry sponge pad starts to wipe the protective glass and removes the residual detergent into The adsorption is carried out, and a clean protective glass is left after the complete reset, which greatly improves the publicity effect of the advertisement and avoids blurring and the like; (2) The present invention designs a protective storage mechanism. When encountering bad weather, the billboard is remotely controlled by a wireless control component. Similarly, the first drive motor starts to drive the corresponding transmission sprocket and the first rotating rod to rotate between the two supporting bearing vertical plates to realize the drive of the two limit connection blocks. During the process of the limit connection block descending, the sliding fixed bar will be driven to descend, thereby pulling the protective cloth rolled up on the winding rod. The rotation of the winding rod will compress the coil springs at both ends until the sliding After the fixing strip reaches the bottom, the triangular fitting strip at the bottom of the sliding fixing strip fits with the inclined surface at the top of the bottom fitting plate, which can achieve a good sealing effect. The protective cloth completely covers the protective glass, plays a protective role for the protective glass, and greatly reduces the degree of loss of the protective glass; (3) The present invention utilizes the space inside the supporting shell by designing a rear-end storage mechanism. Then, items such as replaceable cleaning sponge pads and detergent can be stored on multiple central partitions in the embedded fixed shell, which is convenient for subsequent use, and automatic addition of detergent can be achieved through the internal structure of the liquid storage tank.

During the cleaning cycle, dust from the outside will continuously accumulate on the outer surface of the protective glass 302 during the operation of the billboard. After the set cycle is reached, the pre-cleaning spray mechanism 7 starts to work, wherein the micro pump 710 starts to extract the washing liquid from the liquid storage tank 711, and then enters the nozzle 708 through the spray pipe 709, and starts to spray the cleaning sponge pad 509, so that the cleaning sponge pad 509 absorbs the washing liquid. The second drive motor 705 starts to drive the ball screw 703 to rotate between the two bearing blocks 702, and then drives the ball transmission sleeve 706 to move. Under the sliding limit of the limit plate 707, the ball transmission sleeve 706 and the limit plate 707 drive the nozzle 708 to move horizontally, and then starts to spray the entire cleaning sponge pad 509.After reaching the other end, the second drive motor 705 drives the ball screw 703 to reverse, realizes the reverse movement and reset of the ball transmission sleeve 706, thereby realizing two sprayings. After resetting, the micro pump 710 stops working, thereby completing the spraying of the cleaning sponge pad 509, improving the subsequent cleaning effect, and the remaining amount of cleaning liquid in the liquid storage tank 711 can be clearly observed through the transparent strip shell 715, and then the threaded sleeve 713 can be opened to add liquid through the threaded liquid filling port 712. The front top of the supporting shell 301 is provided with a strip through hole corresponding to the limit plate 707, which ensures that the limit plate 707 can drive the spray head 708 to slide in the strip through hole, realizing spraying and also playing the role of sliding limit. Later, when the cleaning liquid in the liquid storage tank 711 is about to be exhausted, the liquid level control sensor 717 senses that the cleaning liquid has reached the lowest liquid level, and then controls the solenoid valve 718 to open, and the tap water pipe connected to the tap water inlet pipe 719 starts to supply water to the liquid storage tank 7 11, and then the liquid level control sensor 717 detects that the liquid level has reached the set value and controls the solenoid valve 718 to close. During this process, as the liquid level rises, the float 726 is pushed up, and then the sliding rod 725 is pushed on the inner wall of the extension limit shell 724 until the solid detergent 723 is pushed to the top and ejected from the top opening at one end of the support sleeve 720. Then it falls into the liquid storage tank 711 and dissolves, and begins to turn the tap water into cleaning liquid, thereby realizing automatic addition of cleaning liquid. The multiple solid detergents 723 are always in an extruded state under the elastic force of the extrusion spring 721. Subsequent addition of solid detergents 723 can be done by pushing the extrusion block 722 to compress the extrusion spring 721 and add the solid detergents 723 one by one from the through hole at the top end of the support sleeve 720. The bottom pad 727 can support the float 726 when the liquid level is low, preventing the sliding rod 725 from breaking away from the limit of the extension limit shell 724.

[0028] like Figures 1-16As shown, the rear end face of the billboard display support mechanism 3 is fixedly connected to the rear end storage mechanism 8, and the rear end storage mechanism 8 includes an embedded fixed shell 801 fixedly connected to the rear end of the support shell 301, and a plurality of central partitions 802 are fixedly connected to the inner wall of the embedded fixed shell 801. The rear end of the inner wall of the embedded fixed shell 801 is slidably connected to two sliding door panels 803. The rear end faces of the two sliding door panels 803 are fixedly connected to a card block 804 on the side away from each other, and the two sliding door panels 803 are fixedly connected to a sealing strip 805 on the side close to each other. The embedded fixed shell 801 utilizes the space inside the supporting shell 301, and items such as replaceable cleaning sponge pads 509 and detergent can be stored on the multiple central partitions 802 inside the embedded fixed shell 801 to facilitate subsequent use. Sealing is achieved through two sliding door panels 803, and locking is achieved through the block 804 and the snap lock body 9. The two sealing strips 805 can block the gap between the two sliding door panels 803 to prevent dust from entering. The billboard displays that the rear end face of the support mechanism 3 is equipped with snap lock bodies 9 on both sides of the rear end storage mechanism 8.

[0029] The working principle of this embodiment is as follows: when in use, the image data is displayed on the display screen 304 through the display output component 305 to realize advertising. At the same time, different advertising data can be stored through the data storage component 306 for cyclic playback. The entire billboard can be remotely controlled through the wireless control component 307. During the use of the billboard, a cleaning cycle is set. During the operation of the billboard, external dust will continuously accumulate on the outer surface of the protective glass 302. After reaching the set cycle, the pre-cleaning spray mechanism 7 starts to work, wherein the micro pump 710 starts to extract the washing liquid in the liquid storage tank 711, and then enters the cleaning pipe 709. The nozzle 708 enters and starts to spray the cleaning sponge pad 509, so that the cleaning sponge pad 509 absorbs the detergent, and the second drive motor 705 starts to drive the ball screw 703 to rotate between the two bearing blocks 702, thereby driving the ball transmission sleeve 706 to move, and under the sliding limit of the limit plate 707, the ball transmission sleeve 706 and the limit plate 707 drive the nozzle 708 to move horizontally, and then start to spray the entire cleaning sponge pad 509. After reaching the other end, the second drive motor 705 drives the ball screw 703 to reverse, realizing the reverse movement and reset of the ball transmission sleeve 706, thereby realizing two spraying operations. After resetting, the micro pump 710 stops working; Then the first driving motor 409 starts to drive the corresponding transmission sprocket 404 and the first rotating rod 402 to rotate between the two supporting bearing vertical plates 401, and realizes transmission through multiple transmission sprockets 404 and two transmission chains 405, so that the two transmission chains 405 start to simultaneously drive the two limit connection blocks 407 to move downward, and at the same time, the top folding plastic plate 410 of the limit connection block 407 is opened, and the bottom folding plastic plate 410 is folded and retracted, always maintaining a sealed state to prevent external dust from entering. In the process of the two limit connection blocks 407 driving the sliding fixing bar 507 to slowly descend The cleaning sponge pad 509 that absorbs detergent first starts to wipe the protective glass 302, soaking the dust with detergent, and then the hard sponge pad 510 continuously scrapes the dust off to achieve cleaning until it reaches the bottom. Then the first drive motor 409 starts to drive the first rotating rod 402 to reverse, and the sliding fixed bar 507 is reset through the two transmission chains 405. During the upward movement of the sliding fixed bar 507, the dry sponge pad 511 starts to wipe the protective glass 302 and absorb the residual detergent. After complete reset, a clean protective glass 302 is left. When encountering bad weather, the billboard is remotely controlled through the wireless control component 307. Similarly, the first drive motor 409 starts to drive the corresponding transmission sprocket 404 and the first rotating rod 402 to rotate between the two supporting bearing vertical plates 401, thereby driving the two limit connecting blocks 407. When the limit connecting block 407 descends, the sliding fixing bar 507 will be driven to descend, thereby pulling the protective cloth 505 wound on the winding rod 504. The rotation of the winding rod 504 will compress the coil springs 506 at both ends until the sliding fixing bar 507 reaches After reaching the bottom, the triangular fitting strip 508 at the bottom of the sliding fixing strip 507 fits with the inclined surface at the top of the bottom fitting plate 6, which can achieve a good sealing effect. The protective cloth 505 completely covers the protective glass 302 and plays a protective role for the protective glass 302. When it is released later, the first driving motor 409 starts to drive the first rotating rod 402 to reverse, driving the sliding fixing strip 507 to rise. At the same time, under the action of the two winding springs 506, the winding rod 504 will be actively driven to rewind the protective cloth 505 until it is completely restored. When the cleaning liquid in the liquid storage tank 711 is about to be exhausted, the liquid level control sensor 717 senses that the cleaning liquid has reached the lowest liquid level, and then controls the solenoid valve 718 to open, and the tap water pipe connected to the tap water access pipe 719 begins to flush tap water into the liquid storage tank 711. Then the liquid level control sensor 717 detects that the liquid level has reached the set value and controls the solenoid valve 718 to close. In this process, as the liquid level rises, the float 726 will be pushed up, and then the sliding rod 725 will be pushed on the inner wall of the extension limit shell 724 until the solid cleaning agent 723 is pushed to the top and pushed out from the top opening at one end of the support sleeve 720, and then falls into the liquid storage tank 711 and melts, and begins to convert tap water into cleaning liquid, thereby realizing automatic addition of cleaning liquid.
