Description

Technical Field

[0001] This utility model relates to the field of elevator human-machine interaction display technology, specifically an elevator human-machine interaction display based on the Internet. Background Technology

[0002] With the rapid development of the Internet of Things and smart elevator technology, human-machine interface displays with voice interaction and recording functions are being used more and more widely in the elevator field. These displays integrate audio modules to achieve functions such as voice broadcasting, fault alarm recording, and passenger voice interaction, significantly improving the intelligence level of elevator operation and the riding experience, and have become an important part of modern elevators. However, in the existing elevator human-machine interaction display screens, the audio modules mostly adopt an exposed fixed installation structure, that is, the audio modules are directly exposed on the surface of the display screen or the inner wall of the elevator car. This installation method has many inherent drawbacks. The limited space inside the elevator car makes it easy for the exposed audio module to bump into passengers, which may not only cause inconvenience to passengers but also easily lead to damage to the audio module's casing and loosening of internal components, affecting its normal operation. At the same time, the frequent flow of people inside the elevator car means that dust and moisture in the air can easily adhere to key parts of the audio module, such as the pickup holes and wiring terminals. Over time, this accumulation can cause problems such as poor contact and signal interference, reducing the recording clarity and voice interaction stability of the audio module and shortening its service life.

[0003] Therefore, an Internet-based human-machine interaction display screen for elevators is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an Internet-based elevator human-machine interaction display screen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An internet-based elevator human-machine interaction display screen includes a display screen body, a hidden slot inside the display screen body, an audio module inside the hidden slot, and a moving mechanism on the outside of the audio module. The moving mechanism includes a bearing housing, a rotating handle is rotatably engaged inside the bearing housing, a lead screw is fixedly connected to the outside of the rotating handle, a moving block is threadedly connected to the outside of the lead screw, a running groove is opened inside the display screen body, a connecting rod is fixedly connected to the outside of the moving block, and a sliding groove is opened between the hidden groove and the running groove.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Please see Figures 1-5 This utility model provides a technical solution: An Internet-based elevator human-machine interaction display screen includes a display screen body 1, a hidden slot 2 inside the display screen body 1, an audio module 3 inside the hidden slot 2, and a moving mechanism 4 on the outside of the audio module 3. The moving mechanism 4 includes a bearing seat 41, a rotating handle 42 is rotatably engaged inside the bearing seat 41, a lead screw 43 is fixedly connected to the outside of the rotating handle 42, a moving block 44 is threadedly connected to the outside of the lead screw 43, a running groove 45 is opened inside the display screen body 1, a connecting rod 46 is fixedly connected to the outside of the moving block 44, and a sliding groove 47 is opened between the hidden groove 2 and the running groove 45.

[0019] It should be noted that: the hidden groove 2 is located inside the lower part of the display screen body 1, the bearing seat 41 is fixedly connected to the bottom outer side of the display screen body 1, the lead screw 43 is rotatably connected to the inside of the operating groove 45, the moving block 44 is slidably connected to the inside of the operating groove 45, the hidden groove 2 and the operating groove 45 are in a state of communication through the sliding groove 47, the connecting rod 46 is slidably connected to the inside of the sliding groove 47, and the end of the connecting rod 46 away from the moving block 44 is fixedly connected to the outside of the audio module 3, and the initial position of the audio module 3 is inside the hidden groove 2.

[0020] Furthermore, the main body of the display screen 1 serves as the core support carrier of the device. A hidden groove 2 is provided inside the display screen to house the audio module 3. A rotating groove 45 is also provided inside the display screen to provide space for the transmission of the moving mechanism 4. A sliding groove 47 is provided between the hidden groove 2 and the rotating groove 45 to allow the connecting rod 46 to pass through and slide. This groove serves as the installation base for each functional component. The audio module 3 is installed inside the hidden groove 2 and is fixedly connected to the connecting rod 46 and the nylon rod 32 on the outside. It is the core component for realizing the voice interaction and recording functions of the elevator human-machine interface. It can extend or retract from the hidden groove 2 under the drive of the moving mechanism 4.

[0021] Specifically: the connecting rod 46 is slidably connected inside the sliding groove 47, and its two ends are fixedly connected to the moving block 44 and the audio module 3 respectively, which plays the role of force transmission. It can move with the moving block 44 to pull the audio module 3 to extend or retract into the hidden groove 2. The sliding groove 47 connects the hidden groove 2 and the operating groove 45, providing a channel for the movement of the connecting rod 46 and preventing the connecting rod 46 from deviating.

[0022] As a further implementation of this solution, a movable tube 31 is fixedly connected to the inner wall of the hidden groove 2, and a nylon rod 32 is movably engaged inside the movable tube 31. A return spring 33 is sleeved on the nylon rod 32.

[0023] It should be noted that the movable tubes 31 are symmetrically distributed on the inner wall of the hidden groove 2, and the end of the nylon rod 32 away from the movable tubes 31 is fixedly connected to the outside of the audio module 3.

[0024] Furthermore: The initial state of the audio module 3 is that it is stored in the hidden slot 2 below the main body of the display screen 1. At this time, the moving block 44 of the moving mechanism 4 is in the initial position of the operating slot 45, the connecting rod 46 is attached to the inner wall of the sliding slot 47, and the movable tube 31, nylon rod 32 and return spring 33 symmetrically arranged on the inner wall of the hidden slot 2 are in a naturally extended state, while the end of the nylon rod 32 is in close contact with the outside of the audio module 3.

[0025] Specifically: The reset spring 33 is sleeved on the outside of the nylon rod 32. When the audio module 3 retracts into the hidden slot 2, it is compressed, releasing elastic potential energy to push the nylon rod 32 to reset, forming elastic support for the audio module 3 and preventing the audio module 3 from shaking due to the bumps of the elevator operation.

[0026] Workflow: When the recording and voice interaction functions of the audio module 3 need to be activated, the operator rotates the rotating handle 42 inside the bearing seat 41 at the bottom of the display screen body 1. The rotating handle 42 drives the lead screw 43, which is fixedly connected to it, to rotate synchronously in the operating groove 45. Since the lead screw 43 and the moving block 44 are threadedly connected, and the moving block 44 is limited by the operating groove 45 and cannot rotate with the lead screw 43, the rotational motion of the lead screw 43 will be converted into the linear motion of the moving block 44 along the length direction of the operating groove 45. When the moving block 44 moves, it will drive the connecting rod 46, which is fixedly connected to its outer side, to slide synchronously along the sliding groove 47. The end of the connecting rod 46 away from the moving block 44 is fixedly connected to the audio module 3, thereby pulling the audio module 3 outward along the hidden groove 2 until the audio module 3 is fully extended out of the hidden groove 2 and in the designated working position. At this time, the operator can start the audio module 3 to perform the relevant functions. When the audio module 3 needs to be stored, the operator rotates the handle 42 in the opposite direction, causing the lead screw 43 to rotate in the opposite direction as well. This causes the moving block 44 and the connecting rod 46 to move in the opposite direction, and the audio module 3 moves into the hidden slot 2 under the traction of the connecting rod 46. During this process, the outer side of the audio module 3 will squeeze the nylon rod 32, causing the nylon rod 32 to retract into the movable tube 31. The return spring 33, which is sleeved on the outer side of the nylon rod 32, is compressed and undergoes elastic deformation. When the audio module 3 is completely retracted into the hidden slot 2, the elastic potential energy of the return spring 33 is released, pushing the nylon rod 32 to return to its original position. This provides continuous elastic support to the audio module 3, preventing it from shaking or shifting during the elevator's operation and ensuring the stability of its stored state. Throughout the entire operation, the hidden groove 2 and the operating groove 45 are kept connected through the sliding groove 47, providing a stable transmission path for the movement of the connecting rod 46. The external bearing seat 41 of the moving mechanism 4 is designed to facilitate manual control by the operator, while reducing the difficulty of later maintenance and ensuring that the device can operate stably for a long time.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
