Description

Technical Field

[0001] This invention belongs to the technical field of combined audio-visual equipment, and in particular relates to a soundproof tourism information display screen. Background Technology

[0002] Tourist information display screens are an indispensable and important facility in modern tourism services. They are usually placed in tourist attractions to promote the unique areas within the attraction and to provide unfamiliar tourists with detailed information about the attraction, such as tour routes and attraction descriptions.

[0003] Currently, display screens used for tourism information consultation typically promote information about various attractions within a scenic area by playing videos and combining them with voice messages. Tourists can also interact with the display screen to inquire about detailed information and routes for each attraction, making it easier for them to plan their next visit. However, since there may be many tourists and external noise within the scenic area, it is necessary to shield external noise to reduce interference with the voice information played on the display screen. This ensures that users can accurately hear the voice information played by the display screen, such as the soundproof tourism information consultation display screen disclosed in patent publication number CN204303311U.

[0004] The aforementioned patent discloses a display device that uses headphones to block external sounds from affecting the voice information played on the information display screen. However, due to the large number of tourists, cross-infection of bacteria can easily occur when different tourists use headphones. Secondly, after tourists finish using the device, the sound played by the display screen cannot spread to the outside due to the headphones, affecting the promotional effect of the display screen on the scenic spot. Furthermore, since the display screen is placed outdoors, external light can easily affect the clarity of the display screen when people are near it. Summary of the Invention

[0009] Preferably, the circulating heat dissipation mechanism includes an air pump fixedly installed on the upper end of the base, and the output end of the air pump is connected to the air supply chamber. The air supply chamber and the mounting chamber share an air supply hole. The side wall of the mounting chamber has two serpentine holes, both of which are connected to the interior of the display screen housing. The suction end of the air pump is fixedly connected to an air suction pipe, and the air suction pipe is connected to the interior of the top base. A first normally open solenoid valve is installed inside both the air supply hole and the air suction pipe.

[0014] Compared with existing technologies, the advantages of a soundproof tourist information display screen are:

[0015] 1. Through the coordinated operation of the display screen casing, touch screen components, voice player, and control motherboard, the scenic area can be promoted through display and voice playback, and tourists can also inquire about information within the scenic area. Furthermore, the coordinated operation of the top mount, base, curved standing area, curved sound insulation panel, and drive mechanism automatically isolates users from noisy external environments, reducing the impact of external noise on users and minimizing the influence of external light on the display effect of the touch screen components, effectively improving the usability of the information display screen.

[0016] 2. Through the coordinated use of the installation cavity, air supply cavity, circulating heat dissipation mechanism, and helium, which is an inert gas with good thermal conductivity, the display screen can not only dissipate heat quickly inside the casing, but also greatly reduce the possibility of the display screen burning, making it suitable for complex outdoor environments.

[0017] 3. By combining the noise triggering mechanism and the vacuuming component, the sound insulation performance of the two curved sound insulation panels can be further improved by vacuuming when there is a lot of external noise, thereby minimizing the impact of external noise on the sound playback effect of the display screen.

[0018] 4. Through the cooperation of the screen detection mechanism and the prompting mechanism, the screen can be automatically detected for deformation, scratches and other defects on its outer surface when it is not in use each day. This will automatically remind personnel to repair and handle the screen when deformation, scratches, or excessive dust appear on its outer surface. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] like Figures 1-8 As shown, a soundproof tourist information display screen includes a display shell 1, a touch screen assembly 2, two voice players 3, and a control motherboard 4. The touch screen assembly 2 and the two voice players 3 are all installed inside the display shell 1, with the display end of the touch screen assembly 2 and the sound output ends of the two voice players 3 penetrating the side wall of the display shell 1. A top mount 5 is fixedly installed at the upper end of the display shell 1, and a base 6 is fixedly installed at the lower end of the display shell 1. An installation cavity 7 is formed inside the base 6, and the control motherboard 4 is installed inside the installation cavity 7. An arc-shaped standing area 8 is provided on the front side wall of the base 6. Two arc-shaped soundproofing plates 9 are rotatably connected to the base 6 and the top mount 5. 6. Two drive mechanisms 10 are installed to drive the arc-shaped sound insulation plate 9 to rotate. Both drive mechanisms 10 include a mounting plate 101 fixedly installed on the upper end of the base 6. The mounting plate 101 is located on the rear side of the display screen housing 1. A drive motor 102 is installed on the end face of the mounting plate 101. The output end of the drive motor 102 is connected to a moving gear 103. An arc-shaped gear rack 104 is fixedly installed on the inner wall of the arc-shaped sound insulation plate 9. The moving gear 103 is meshed with the arc-shaped gear rack 104. The drive motor 102 is electrically connected to the control main board 4. The drive motor 102 is a forward and reverse motor. It can drive the moving gear 103 to rotate in the forward direction or in the reverse direction.

[0030] Both arc-shaped sound insulation panels 9 are equipped with noise triggering mechanisms 11 on their side walls. Each noise triggering mechanism 11 includes a conical sleeve 111 fixedly installed on the outer side wall of the arc-shaped sound insulation panel 9. A piezoelectric ceramic component 112 is installed on the outer side wall of the arc-shaped sound insulation panel 9 at the position inside the conical sleeve 111. An electromagnetic switch 113 is fixedly installed on the outer side wall of the conical sleeve 111. The piezoelectric ceramic component 112 is electrically connected to the electromagnetic switch 113 through the control main board 4. When the piezoelectric ceramic component 112 vibrates and deforms, the positive and negative charge centers inside the piezoelectric ceramic component 112 undergo relative displacement, thereby generating a polarization phenomenon and forming a current signal. This is a mature existing technology, so it will not be described in detail here.

[0031] The base 6 has an internal air supply chamber 12. The top seat 5 is hollow and connected to the interior of the display screen housing 1. The top seat 5, the air supply chamber 12, and the mounting cavity 7 are all equipped with a circulating heat dissipation mechanism 13. The circulating heat dissipation mechanism 13 includes an air pump 131 fixedly installed on the upper end of the base 6, and the output end of the air pump 131 is connected to the air supply chamber 12. The air supply chamber 12 and the mounting cavity 7 are both provided with an air supply hole 132. The side wall of the mounting cavity 7 has two serpentine holes 133, both of which are connected to the interior of the display screen housing 1. The suction end of the air pump 131 is fixedly connected to the suction pipe 134, and the suction pipe 134 is connected to the interior of the top seat 5. The air supply hole 132 and the suction pipe 134 are both equipped with a first normally open solenoid valve 135. The air pump 131 and the first normally open solenoid valve 135 are both electrically connected to the control main board 4. The base 6 and the top seat 5 are both made of materials with good thermal conductivity. When the helium gas 15 inside the display screen housing 1 is extracted, it can exchange heat with the external air environment through the base 6 and the top seat 5, thereby achieving the effect of assisting the heat dissipation inside the display screen housing 1.

[0032] Both of the two arc-shaped sound insulation panels 9 have an air storage chamber 14 inside. The two air storage chambers 14, the air supply chamber 12, the display screen shell 1 and the top seat 5 are all filled with helium gas 15. The circulating heat dissipation mechanism 13 and the two air storage chambers 14 are jointly equipped with a vacuum assembly 16. The vacuum assembly 16 includes a three-way pipe 161 that is fixedly inserted into the side wall of the suction pipe 134. The two ports of the three-way pipe 161 are fixedly connected to the corresponding air storage chambers 14 with connecting hoses 162. The three-way pipe 161 is equipped with a first normally closed solenoid valve 163 that is electrically connected to the control main board 4. Under the action of the connecting hoses 162, the normal movement of the arc-shaped sound insulation panel 9 will not be affected.

[0033] The base 6 has an internal gas storage and pressure reduction mechanism 17 that communicates with the gas supply chamber 12. The gas storage and pressure reduction mechanism 17 includes two temporary storage slots 171 inside the base 6. The openings of the two temporary storage slots 171 are fixedly connected to frame sleeves 172. Piston plates 173 are slidably installed inside the two frame sleeves 172. A set of springs 174 is fixedly installed between the two piston plates 173 and the temporary storage slots 171 on the same side. The bottoms of the two temporary storage slots 171 and the gas supply chamber 12 are both fixedly connected to a fixed pipe 175. The two fixed pipes 175 are each equipped with a second normally closed solenoid valve 176 that is electrically connected to the control main board 4. Helium gas extracted from the arc-shaped sound insulation plate 9 can be temporarily stored through the temporary storage slots 171.

[0034] Two arc-shaped sound insulation panels 9 and the display screen housing 1 are jointly equipped with a screen detection mechanism 18. The screen detection mechanism 18 includes a strip light panel 181 fixedly installed on the upper part of the front side wall of the display screen housing 1. The strip light panel 181 is located above the display end of the touch screen assembly 2. The light-emitting surface of the strip light panel 181 is located at the bottom of the strip light. Insulating frames 182 are fixedly inserted into the inner side walls of the two arc-shaped sound insulation panels 9. A photosensitive strip 183 is fixedly installed inside the two insulating frames 182. A transparent plate 184 is fixedly encapsulated at the frame opening of the two insulating frames 182. The strip light panel 181 and the photosensitive strip 183 are electrically connected to the control main board 4. The photosensitive strip 183 is made of photoresistor material. When the light intensity increases, the resistance of the photosensitive strip 183 decreases.

[0035] Furthermore, the air supply chamber 12 is equipped with a prompting mechanism 19 that cooperates with the screen detection mechanism 18. The prompting mechanism 19 includes an air pressure chamber 191 opened inside the base 6. The air pressure chamber 191 and the air supply chamber 12 share a connecting hole 192. A third normally closed solenoid valve 193 is installed inside the connecting hole 192. The connecting hole 192 and the mounting cavity 7 share a diversion hole 194, and a second normally open solenoid valve 195 is installed inside the diversion hole 194. An air pressure detector 19 is installed on the end face of the base 6. 6. The detection end of the air pressure detector 196 extends into the air pressure chamber 191. The two photosensitive strips 183 are electrically connected to the third normally closed solenoid valve 193 and the second normally open solenoid valve 195 through the control motherboard 4. The air pressure detector 196 is electrically connected to the two voice players 3 through the control motherboard 4. The air pressure detector 196 can detect the air pressure inside the air pressure chamber 191 in real time, and can transmit an electrical signal to the control motherboard 4 when the air pressure exceeds the standard. This is a mature existing technology, so it will not be described in detail here.

[0036] The operating principle of this invention is explained as follows: The entire device is installed in a suitable location within the scenic area (such as the intersection of multiple attractions). Then, the control motherboard 4 is connected to the external power supply circuit, and the control motherboard 4 is then activated. The control motherboard 4 controls the touch screen component 2 and the voice player 3 to work. The touch screen component 2 will play the corresponding scenic area introduction video content, while the voice player 3 will play the corresponding voice information. When people want to inquire about information such as attractions within the scenic area, they first stand in the arc-shaped standing area 8 of the base 6, and then they can operate the touch screen component 2 by touch. The touch screen component 2 will then display the corresponding video content in detail, and the voice player 3 will play the corresponding voice information.

[0037] When a person touches the large screen component 2 at the slot, the control motherboard 4 will immediately control the two drive motors 102 to work for 15 seconds at a time. At this time, the two drive motors 102 can drive the two arc-shaped sound insulation plates 9 to rotate in opposite directions through the same-side moving gear 103 and arc-shaped gear rack 104. After the two drive motors 102 finish working at the timed time, the two arc-shaped sound insulation plates 9 rotate to the front of the display screen component. At this time, the person is located inside the two arc-shaped sound insulation plates 9. Utilizing the sound insulation performance of the two arc-shaped sound insulation plates 9 themselves, the transmission of external noise to the person inside the arc-shaped sound insulation plates 9 can be blocked. The sound played by the voice player 3 is limited to the inside of the arc-shaped sound insulation plates 9, so that the person can hear the voice information clearly. In addition, the arc-shaped sound insulation plates 9, together with the top seat 5 and the base 6, can block the external light as much as possible, thereby improving the display effect of the touch screen component 2.

[0038] During normal operation, the control board 4 controls the air pump 131 to start working. At this time, the suction end of the air pump 131 can draw out the helium 15 from the top seat 5 and the display shell 1 through the suction pipe 134 and deliver it to the air supply chamber 12. Then, it enters the mounting chamber 7 through the air supply hole 132 and finally flows back to the interior of the display shell 1 through the two serpentine holes 133. Since the base 6 has a large area, the helium 15 can exchange heat with the external environment through the base 6 when passing through the mounting chamber 7 and the serpentine holes 133 inside the base 6. This can quickly dissipate the heat generated by the display components and prevent the heat inside the display shell 1 from accumulating too much when working outdoors, which would affect the normal operation of the touch screen component 2 and the control board 4.

[0039] Simultaneously, after the two arc-shaped sound insulation plates 9 stop rotating, the control board 4 supplies power to the power supply circuit inside the electromagnetic switch 113 based on the electrical signal from the piezoelectric ceramic component 112. When external noise reaches the two conical sleeves 111, the external sound waves cause the two piezoelectric ceramic components 112 to vibrate and deform, resulting in a relative displacement of the positive and negative charge centers inside the piezoelectric ceramic component 112, thus generating polarization and forming a current signal. The control board 4 then rectifies and amplifies the electrical signal generated by the piezoelectric ceramic component 112 before feeding it into the electromagnetic switch 113. If the external noise is too loud, the sound wave intensity will be lower than... When the external noise is high, the vibration amplitude and frequency generated by the piezoelectric ceramic component 112 are large, and the electrical signal intensity generated by the piezoelectric ceramic is also large. Therefore, after rectification and amplification by the control motherboard 4, the current flowing into the electromagnetic switch 113 is large. At this time, the electromagnetic component inside the electromagnetic switch 113 will generate sufficient magnetic attraction to close its moving contact. The control motherboard 4 will then receive the closing electrical signal of the electromagnetic switch 113. If the external noise is low, the electrical signal intensity generated by the piezoelectric ceramic component 112 is low. At this time, the current flowing into the electromagnetic switch 113 is small, so the moving contact of the electromagnetic switch 113 will not close, and the control motherboard 4 will not receive the closing electrical signal of the electromagnetic switch 113.

[0040] When the control board 4 receives the closing electrical signal of the electromagnetic switch 113, the control board 4 will immediately control the first normally closed solenoid valve 163 inside the three-way pipe 161, the first normally open solenoid valve 135 inside the air supply port 132 and the air intake pipe 134, the second normally open solenoid valve 195 inside the diversion port 194, and the second normally closed solenoid valve 176 inside the two fixed pipes 175 to be energized for 30 seconds. At this time, the suction end of the air pump 131 will draw out the helium 15 inside the two arc-shaped sound insulation panels 9 through the air intake pipe 134, the three-way pipe 161 and the two connecting hoses 162, and deliver it to the two temporary storage tanks 171 through the air supply chamber 12 and the fixed pipes 175. At this time, because the amount of helium 15 inside the temporary storage tanks 171 increases, it can push the two piston plates 173 to move upward, thereby accommodating the helium 15 drawn out from the two arc-shaped sound insulation panels 9, and preventing the increase of helium 15 from causing excessive air pressure inside the mounting cavity 7 and the display screen housing 1. The helium gas 15 inside the two arc-shaped sound insulation panels 9 is extracted, and a high vacuum state is formed inside the two gas storage chambers 14. At this time, because the medium that can be used for sound transmission inside the arc-shaped sound insulation panels 9 is reduced, the sound transmitted from the outside to the arc-shaped sound insulation panels 9 will be rapidly attenuated. Thus, when the external ambient noise is loud, the arc-shaped sound insulation panels 9 can be automatically vacuumed, further reducing the impact of external noise on users. During the entire process of users querying travel information, if the external noise is relatively low, the electromagnetic switch 113 will not close. At this time, the helium gas 15 inside the two arc-shaped sound insulation panels 9 will not be extracted. The sound insulation performance of the arc-shaped sound insulation panels 9 themselves can meet the sound insulation needs of users. This not only reduces the execution steps (i.e., the step of extracting the helium gas 15 inside the arc-shaped sound insulation panels 9), but also utilizes the good thermal conductivity of helium gas 15 to increase the heat dissipation speed of the inner space of the arc-shaped sound insulation panels 9 during use.

[0041] After the user finishes using the service, they can end the consultation by touching the "End" button on the large screen component 2. At this time, the control motherboard 4 will control the two drive motors 102 to perform a timed reverse drive, causing the two arc-shaped sound insulation panels 9 to rotate in the opposite direction and return to their original positions. The user can then leave the arc-shaped standing area 8. After the two arc-shaped sound insulation panels 9 return to their original positions, the control motherboard 4 will control the first normally closed solenoid valve 163 inside the three-way pipe 161 and the second normally closed solenoid valve 176 inside the two fixed pipes 175 to work for 1 minute at a time. At this time, the helium gas 15 temporarily stored inside the two temporary storage tanks 171 will flow back under the action of the spring 174 and the external air pressure, and the gas storage chamber 14 inside the two arc-shaped sound insulation panels 9 will be refilled with helium gas 15. The heat of the hot air inside the arc-shaped sound insulation panels 9 can be dissipated to the external environment through the conduction of the arc-shaped sound insulation panels 9 and the helium gas 15.

[0042] When the scenic area closes for the end of its operation, the timer module on the control motherboard 4 will start a self-test program. At this time, the control motherboard 4 will control the two drive motors 102 to work at a timed interval, driving the two arc-shaped sound insulation plates 9 to rotate to the front of the touch screen component 2. When the two drive motors 102 are started, the control motherboard 4 will also simultaneously start the strip light panel 181, and after a 3-second delay, connect the connection circuit between the photosensitive strip 183 and the third normally closed solenoid valve 193 and the second normally open solenoid valve 195, and at the same time control the first normally open solenoid valve 135 in the air supply hole 132 to be energized, and the strip light panel 181 will work. It emits a downward-facing strip light. If the screen of the touch screen component 2 is slightly deformed, scratched, or has a lot of dust, the scratches, deformation, and dust will cause light scattering. Therefore, as the photosensitive strip 183 moves with the curved sound insulation plate 9, the light intensity projected onto the photosensitive strip 183 will increase. At this time, the resistance of the photosensitive strip 183 decreases, so the current flowing into the third normally closed solenoid valve 193 and the second normally open solenoid valve 195 increases. At this time, the opening degree of the third normally closed solenoid valve 193 increases, and the closing degree of the second normally open solenoid valve 195 also increases. Therefore, the air... More helium 15 delivered by pump 131 to the air supply chamber 12 will enter the pressure chamber 191 through the third normally closed solenoid valve 193. After the arc-shaped sound insulation plate 9 stops moving, the control board 4 will de-energize and stop the operation of the air pump 131, the third normally closed solenoid valve 193, the second normally open solenoid valve 195, and the first normally open solenoid valve 135 in the air supply port 132. If there is a defect on the surface of the touch screen component 2, more helium 15 will enter the pressure chamber 191. At this time, the pressure detector 196 will detect that the pressure in the pressure chamber 191 is too high. Device 196 transmits electrical signals to the control motherboard 4. Subsequently, the control motherboard 4 controls the two voice players 3 to play corresponding prompt voice messages, and simultaneously controls the two drive motors 102 to drive the two arc-shaped sound insulation plates 9 to rotate and reset until the personnel repair and process the touch screen component 2 and manually clear the alarm message. After the personnel manually clear the alarm message, the control motherboard 4 controls the third normally closed solenoid valve 193 in the connecting hole 192 to work for 10 seconds at a time to discharge the excess helium gas 15 in the air pressure chamber 191 to avoid affecting the next use.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
