Description

Technical Field

[0001] The present invention relates to the technical field of digital display racks, and particularly relates to a display rack for digital exhibitions. Background Art

[0002] Display racks are widely applicable to the display of products such as electronics, electrical appliances, famous cigarettes, famous wines, pharmacies, glasses, handicrafts, crystal products, hotel supplies, cultural supplies, automotive supplies, car models in 4S stores, plastic products, cosmetics specialty stores, factory product exhibition halls, sample halls of foreign trade companies, etc. In the past, traditional display racks were mostly used to display static paper pictures such as product posters or brochures or promotional texts. With the development of technology, digital displays are increasingly used for publicity in various exhibition halls.

[0003] A touch screen is provided on the display rack to control the display screen and its system, which is convenient for visitors to view and understand the exhibits. However, after long-term use, dust and a large number of fingerprints will accumulate on the touch screen, which is not only unsightly and affects the use, but also there are certain hygiene problems. If disinfection and cleaning cannot be carried out in time, the phenomenon of touch cross-infection is likely to occur. Usually, it requires staff to clean manually, which greatly increases their work burden, and only solving the problem by cleaning the touch screen is only a temporary solution and does not address the root cause. Summary of the Invention

[0004] The purpose of the present invention is to provide a display rack for digital exhibitions to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: A display rack for digital exhibitions includes a chassis and a touch screen. A box body is provided at the top of the chassis, and a touch glove is provided inside the box body. It also includes a box cover and a power mechanism for driving the box cover to open or close the box body. A human body sensor is provided on the touch screen. It further includes a controller. The power mechanism and the human body sensor are both electrically connected to the controller. A receiving cavity is provided inside the chassis. A hydraulic rod is provided at the bottom of the receiving cavity. The movable end of the hydraulic rod is provided with a connecting frame, and the connecting frame is fixedly connected to the rear side of the touch screen. The chassis is provided with an opening at the top of the receiving cavity for the connecting frame and the touch screen to extend out. A wiping mechanism, a spraying and washing mechanism, and a blowing mechanism are provided inside the receiving cavity.

[0006] With the above technical solution, the hydraulic rod extends to drive the connecting frame to move upward, thereby driving the touch screen to move upward. The connecting frame and the touch screen extend out of the accommodating cavity through the opening. When a tourist comes to the exhibition stand and needs to watch and understand, the human body sensor receives the signal and transmits it to the controller. The controller controls the power device to drive the box cover to move backward, thereby opening the box body and exposing the touch gloves in the box body. It reminds the tourist to wear the touch gloves before operating, so as to avoid a large amount of fingerprints on the surface and reduce the occurrence of touch cross-infection. When the tourist leaves, the human body sensor receives the signal and transmits it to the controller. The controller controls the power device to drive the box cover to move forward to close the box body. When a large amount of fingerprint dust needs to be cleaned on the surface of the touch screen, the hydraulic rod shortens to drive the connecting frame to move downward, thereby driving the touch screen to move downward and return to the accommodating cavity through the opening. Then, the wiping mechanism and the spraying and washing mechanism are started. The spraying and washing mechanism sprays the cleaning liquid onto the surface of the touch screen, and the wiping mechanism wipes the surface of the touch screen. After the cleaning is completed, the blowing mechanism is started to dry the water on the surface of the touch screen, thus eliminating the need for manual cleaning of the touch screen by the staff and reducing the workload.

[0007] As a further optimization of the present invention, a broadcast speaker is provided on the top of the chassis, and the broadcast speaker is electrically connected to the controller.

[0008] With the above technical solution, when a tourist comes to the exhibition stand and needs to watch and understand, the human body sensor receives the signal and transmits it to the controller. The controller controls the dynamic broadcast speaker to emit sound for broadcasting to remind the tourist to wear the touch gloves.

[0009] As a further optimization of the present invention, the box body is fixed to the left side of the top of the chassis. The power mechanism includes a fixed frame and a cylinder installed on the fixed frame. The fixed frame is located at the rear of the box body and is fixed to the chassis. The movable end of the cylinder is connected to the box body, and the cylinder is electrically connected to the controller.

[0010] With the above technical solution, the cylinder contracts to drive the box cover to move backward, thereby opening the box body, and the cylinder extends to drive the box cover to move forward, thereby closing the box body.

[0011] As a further optimization of the present invention, the wiping mechanism includes a transmission assembly and a wiping assembly. The transmission assembly includes a screw rod, a guide rod, a first movable block and a second movable block respectively sleeved on the screw rod and the guide rod, and a first motor for driving the screw rod to rotate. The screw rod and the guide rod are both located in front of the hydraulic rod. An installation plate is provided on the right inner wall of the accommodation cavity. The two ends of the screw rod are respectively rotatably connected to the installation plate and the top wall of the accommodation cavity. The two ends of the guide rod are respectively fixedly connected to the bottom wall and the top wall of the accommodation cavity. The output end of the first motor passes through the installation plate and is connected to the screw rod. The wiping assembly includes a connecting rod and a wiping roller rotatably sleeved on the connecting rod. The two ends of the connecting rod are respectively detachably connected to the first movable block and the second movable block.

[0012] With the above technical solutions, when the first motor is turned on, it drives the screw rod to rotate, thereby driving the first movable block to move up and down, thereby driving one end of the connecting rod to move up or down. The other end of the connecting rod drives the second movable block to slide up and down along the guide rod, thereby driving the wiping roller to move up to wipe the screen. Since the wiping roller is in contact with the touch screen, rolling friction is generated to make the wiping roller rotate. The two ends of the connecting rod are set to be detachable for easy replacement or cleaning of the wiping roller.

[0013] As a further optimization of the present invention, the spraying and washing mechanism includes a water tank, a water pump and a water outlet member. The water inlet end of the water pump is connected to the water tank, and the water outlet end is connected to the water outlet member. The water outlet member is fixed to the front inner wall of the accommodation cavity. A spray head is provided at the rear of the water outlet member, and the spray head is provided with a plurality of water spray holes.

[0014] With the above technical solutions, there is cleaning liquid in the water tank. When the water pump is turned on, the water pump pumps out the cleaning liquid in the water tank and sends it to the water outlet member. The water outlet will spray the cleaning liquid onto the surface of the touch screen through the water spray holes of the spray head.

[0015] As a further optimization of the present invention, the blowing mechanism includes a plurality of fans. The fans are installed on the front inner wall of the accommodation cavity, and the wind direction of the fans is backward.

[0016] As a further optimization of the present invention, a gear is fixed to the right side of the chassis. A second motor is provided in the accommodation cavity. The output shaft of the second motor passes through the chassis and is connected to the gear. A boss is provided on the left side of the top of the chassis, and a chute is opened on the right side of the boss; it further includes a movable baffle plate whose left end is slidably connected to the chute back and forth, and a gear meshing with the gear is provided below the right end of the movable baffle plate.

[0017] With the above technical solution, when it is necessary to store the touch screen and not use it, the second motor is turned on. The second motor drives the gear to rotate, and the gear drives the rack to move backward, thereby driving the movable baffle to move backward, blocking the opening, preventing foreign objects from falling into the opening and damaging the touch screen, and at the same time blocking the broadcast speaker to prevent it from being contaminated with dust and affecting its service life.

[0018] As a further optimization of the present invention, the connecting rod is connected to the first movable block and the second movable block by screws.

[0019] As a further optimization of the present invention, a plurality of ventilation holes are provided on both the left and right side walls of the chassis.

[0020] With the above technical solution, the air permeability in the accommodation cavity is ensured, and moisture and mildew are prevented.

[0021] As a further optimization of the present invention, a drain hole is provided on the bottom wall of the chassis, support feet are provided at the bottom of the chassis, and a detachable water receiving box is provided between the support feet.

[0022] As a further optimization of the present invention, the liquid after cleaning the touch screen can be discharged through the drain hole into the water receiving box, and the liquid can be poured out by disassembling the water receiving box.

[0023] The beneficial effects of the present invention are as follows: The hydraulic rod extends to drive the connecting frame to move upward, thereby driving the touch screen to move upward. The connecting frame and the touch screen extend out of the accommodation cavity through the opening. When a tourist comes to the exhibition stand and needs to view and understand, the human body sensor receives the signal and transmits the signal to the controller. The controller controls the power device to drive the box cover to move backward, thereby opening the box body and exposing the touch gloves in the box body, reminding the tourist to wear the touch gloves before operating, thereby avoiding a large amount of fingerprints on the surface and reducing the occurrence of touch cross-infection. When the tourist leaves, the human body sensor receives the signal and transmits the signal to the controller. The controller controls the power device to drive the box cover to move forward to close the box body. When a large amount of fingerprints and dust are contaminated on the surface of the touch screen and need to be cleaned, the hydraulic rod shortens to drive the connecting frame to move downward, thereby driving the touch screen to move downward through the opening and return to the accommodation cavity. Then, the wiping mechanism and the spraying mechanism are turned on. The spraying mechanism sprays the cleaning liquid onto the surface of the touch screen, and the wiping mechanism wipes the surface of the touch screen. After cleaning, the blowing mechanism is turned on to blow dry the water on the surface of the touch screen, thereby eliminating the need for manual cleaning of the touch screen by the staff and reducing the work burden.

[0038] The blowing mechanism includes a number of fans 7. The fans 7 are installed on the front inner wall of the receiving cavity 12, and the wind direction of the fans 7 is backward. Specifically, four fans 7 are provided and are distributed at the four corners;

[0039] Further, a gear 81 is fixed to the right side of the chassis 1. Inside the receiving cavity 12, there is a second motor 8. The output shaft of the second motor 8 passes through the chassis 1 and is connected to the gear 81. On the left side of the top of the chassis 1, there is a boss 13. A chute 131 is opened on the right side of the boss 13; It also includes a movable baffle 3 whose left end is slidably connected to the front and rear of the chute 131. Below the right end of the movable baffle 3, there is a gear 81 meshing with the gear 81.

[0040] Further, a number of ventilation holes 17 are opened on both the left and right side walls of the chassis 1;

[0041] Further, a drain hole 16 is provided in the bottom wall of the chassis 1, and support feet 9 are provided at the bottom of the chassis 1. A detachable water receiving box 91 is provided between the support feet 9.

[0042] The principle of the present invention is that when the hydraulic rod 2 extends, it drives the connecting frame to move upward, thereby driving the touch screen 11 to move upward. The connecting frame and the touch screen 11 extend out of the accommodating cavity 12 through the opening 121.

[0043] When a tourist comes to the exhibition stand and needs to view and understand, after the human body sensor receives the signal, it transmits the signal to the controller. The controller controls the power device to drive the box cover 41 to move backward, thereby opening the box body 4 and exposing the touch gloves 42 inside the box body 4. The controller controls the broadcast speaker 44 to sound for broadcasting, reminding the tourist to wear the touch gloves 42 before operating, so as to avoid a large amount of fingerprints on the surface and reduce the occurrence of touch cross-infection. When the tourist leaves, after the human body sensor receives the signal, it transmits the signal to the controller. The controller controls the power device to drive the box cover 41 to move forward to close the box body 4.

[0044] When a large amount of fingerprints and dust are stained on the surface of the touch screen 11 and need to be cleaned, the hydraulic rod 2 shortens to drive the connecting frame to move downward, thereby driving the touch screen 11 to move downward and return to the accommodating cavity 12 through the opening 121. Then, the wiping mechanism and the spraying mechanism are turned on.

[0045] There is cleaning liquid in the water tank 61. The water pump 62 is turned on. The water pump 62 pumps out the cleaning liquid in the water tank 61 and sends it to the water outlet member 63. The water outlet will spray the cleaning liquid onto the surface of the touch screen 11 through the water spraying holes 641 of the nozzle 64.

[0046] Then, the first motor 50 is turned on to drive the screw rod 51 to rotate, thereby driving the first movable block 511 to move up and down, thereby driving one end of the connecting rod 53 to move up or down. The other end of the connecting rod 53 drives the second movable block 521 to slide up and down along the guide rod 52, thereby driving the wiping roller 531 to move up to wipe the screen. Since the wiping roller 531 is in contact with the touch screen 11, rolling friction is generated to make the wiping roller 531 rotate. Both ends of the connecting rod 53 are set to be detachable for easy replacement or cleaning of the wiping roller 531. The liquid after cleaning the touch screen 11 can be discharged through the drain hole 16 into the water receiving box 91, and the liquid can be poured out by disassembling the water receiving box 91.

[0047] Then, a plurality of fans 7 are turned on to blow dry the moisture on the surface of the touch screen 11. A plurality of ventilation holes 17 are provided to ensure the air permeability in the accommodating cavity 12 and prevent moisture and mildew.

[0048] The above operations eliminate the need for manual cleaning of the touch screen 11 by the staff and reduce the work burden.

[0049] Further, when it is necessary to store the touch screen 11 without use, the second motor 8 is turned on. The second motor 8 drives the gear 81 to rotate, and the gear 81 drives the rack 31 to move backward, thereby driving the movable baffle 3 to move backward, blocking the opening 121, preventing foreign objects from falling into the opening 121 and damaging the touch screen 11. At the same time, the broadcast speaker 44 is blocked to prevent it from being contaminated with dust and affecting its service life.

[0050] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made. These improvements and modifications should also be regarded as the protection scope of the present invention.
