Description

Technical Field

[0001] This utility model relates to the field of dual-screen control terminal technology, specifically a dual-screen control terminal. Background Technology

[0002] With the widespread adoption of portable electronic devices, foldable terminals have become increasingly popular due to their compact structure and portability. These devices typically consist of a foldable primary screen and a main operating unit. The main operating unit has operation buttons located on both sides of the screen to meet the user's operational needs in different usage scenarios. When the device is folded, the screen covers the main operating unit, forming a closed state; when the device is unfolded, the screen flips up, revealing a second screen or operating area for easy viewing and operation.

[0003] However, in the closed state, the operation button area of ​​existing folding terminals is often exposed, lacking an effective protection mechanism. For example, in the published patent document CN114873462B, a mobile control terminal for an intelligent tower crane is described, which adopts a double-folding main and secondary display screen structure, and has control joysticks and shortcut function buttons on the left and right sides of the main display screen.

[0004] While the above design offers good operability and display functionality, its structural design means that when folded and closed, the operation button areas on both sides are not effectively covered and remain directly exposed to the external environment. This makes the buttons prone to damage during carrying or storage due to accidental touches, foreign objects intruding, or external impacts, affecting the lifespan and reliability of the device. This problem is particularly prominent when used in industrial, outdoor, or special environments.

[0005] Although some devices have provided partial protection by adding fixed covers or protective sleeves, these solutions often fail to automatically retract when the device is in use, resulting in problems such as obstructing the view and interfering with normal operation, leading to a poor user experience. Utility Model Content

[0006] In view of the technical problems in the prior art, the present invention provides a dual-screen control terminal, which aims to solve the problems that the operation button area of ​​the foldable terminal is exposed and easily damaged when closed, and that the external protective structure interferes with normal operation when unfolded.

[0007] A dual-screen control terminal includes a terminal unit, a mounting bracket, a protective plate, and a limiting structure, wherein... The terminal includes a terminal body and a foldable screen. The foldable screen is hinged to the terminal body, and the terminal body has operation buttons on both sides of the foldable screen. The mounting bracket is detachably mounted on the back of the folding screen; The protective plate includes two plates, which are slidably mounted on both sides of the mounting frame, and their positions correspond to the operation buttons. The protective plate is slidable relative to the mounting bracket, and has a first position covering the operation button and a second position stored in the back of the folding screen; The limiting structure includes two sets, which are respectively disposed on the two protective plates; When the protective plate is in the first position, the limiting structure can be locked to the terminal body; When the protective plate is in the second position, the limiting structure can be locked to the back of the folding screen.

[0008] Optionally, the mounting bracket includes a mounting base and a guide rod, wherein, The mounting base is detachably mounted on the back of the folding screen; The guide rods include two sets, which are respectively located on the corresponding protective plates on both sides of the mounting base. Each set of guide rods includes at least two rods, which are arranged in parallel. One end of each set of guide rods is fixed to the mounting base, and the other end passes through the corresponding protective plate and is slidably connected to it.

[0009] Optionally, the guide rod includes a rod body and a limiting slider, wherein, One end of the rod is fixed to the mounting base, and the other end passes through the corresponding protective plate and is slidably connected to it; The limiting slider is located at one end of the rod that passes through the protective plate, and a cavity is provided in the protective plate corresponding to the limiting slider for its limiting sliding.

[0010] Optionally, the limiting structure includes a limiting insert, wherein, The limiting block is located on the side of the protective plate away from the mounting frame, and the protective plate has a sliding groove corresponding to the limiting block; The limiting block can slide longitudinally within the groove relative to the protective plate.

[0011] Optionally, a first limiting slot is provided on the terminal body at the corresponding limiting plug, so that after the protective plate slides to the first position, the limiting plug is inserted therein for locking; A second limiting slot is provided on the back of the foldable screen at the corresponding limiting block, so that the limiting block can be inserted into and locked after the protective plate slides to the second position.

[0012] Optionally, the limiting structure further includes a slider, which comprises a slider block and a guide post, wherein, The sliding block is fixedly mounted on the side wall of the limiting block, and the side wall of the sliding groove is provided with a movable groove for longitudinal sliding at the location of the sliding block; The guide post is longitudinally connected to the movable groove and slides through the sliding block.

[0013] Optionally, the slider further includes a spring, which is sleeved on the guide post and located on top of the slider block, for applying downward pressure to the slider block.

[0014] Optionally, it also includes two levers, which are symmetrically disposed on the top of the two protective plates to assist the sliding of the protective plates.

[0015] Compared with the prior art, the dual-screen control terminal provided by this utility model has the following advantages: (1) By setting a sliding protective plate on the back of the folding screen, the protective plate can slide to the first position covering the operation buttons when the terminal is folded and closed, thereby effectively avoiding damage to the buttons caused by accidental touch, dust and debris intrusion or external impact; significantly improving the service life and reliability of the device in carrying, storage and in harsh environments such as industrial and outdoor environments; at the same time, when the terminal is unfolded for use, the protective plate can slide to the second position stored on the back of the folding screen, completely giving up the operation area, neither obstructing the screen view nor interfering with the normal operation of the buttons on both sides, overcoming the inherent defects of traditional fixed covers or protective covers that are "in the way when unfolded", and greatly improving the user's operating experience and convenience.

[0016] (2) The protective plate can slide smoothly and accurately through the structure of mounting bracket and guide rod; the design of the limit block and slot in the limit structure ensures that the protective plate can be stably locked in the first and second positions, preventing it from moving in an unexpected state, and ensuring the reliability of protection and stability during use.

[0025] Please see Figure 1-5 The present application proposes a dual-screen control terminal, characterized in that it includes a terminal 1, a mounting frame 2, a protective plate 3, and a limiting structure 4.

[0026] like Figure 1-2 , Figure 5 As shown, the terminal 1 includes a terminal body 11 and a folding screen 12. The folding screen 12 is hinged to the terminal body 11. The terminal body 11 has operation buttons 101 on both sides of the folding screen 12. The mounting bracket 2 is detachably mounted on the back of the folding screen 12. There are two protective plates 3, which are slidably mounted on both sides of the mounting bracket 2, and their positions correspond to the operation buttons 101. The protective plates 3 can slide relative to the mounting bracket 2, and have a first position covering the operation buttons 101 and a second position stored in the back of the folding screen 12. There are two sets of limiting structures 4, which are respectively provided on the two protective plates 3. When the protective plate 3 is in the first position, the limiting structure 4 can be locked with the terminal body 11. When the protective plate 3 is in the second position, the limiting structure 4 can be locked with the back of the folding screen 12.

[0027] Specifically, the terminal 1 constitutes the main body of the device, and the operation buttons 101 on both sides are the main objects of protection; the detachable mounting bracket 2 serves as the supporting foundation of the entire protective mechanism and is fixed to the back of the folding screen 12, ensuring the integrity and portability of the mechanism; the two protective plates 3 are the direct execution components, which, guided by the mounting bracket 2, achieve precise sliding between the two positions of "cover protection" and "storage and concealment", perfectly solving the contradiction in the background technology of "protection when the cover is closed" and "not in the way when the cover is open"; the limiting structure 4 is the key to ensuring that the protective plate 3 is stable and does not move in the working position. Its design of locking to the back of the terminal body 11 and the folding screen 12 respectively makes the protective plate 3 fixed in both the first and second positions, effectively preventing accidental sliding caused by device movement or vibration, greatly improving the reliability of protection and user experience, and fundamentally overcoming the disadvantages of the bulky and cumbersome external protective cover.

[0028] In some embodiments, such as Figure 1-2 As shown, the mounting frame 2 includes a mounting base 21 and guide rods 22. The mounting base 21 is detachably mounted on the back of the folding screen 12. The guide rods 22 include two sets, which are respectively located on both sides of the mounting base 21 at the corresponding protective plates 3. Each set of guide rods 22 includes at least two rods, which are arranged in parallel. One end of each set of guide rods 22 is fixed to the mounting base 21, and the other end passes through the corresponding protective plate 3 and is slidably connected to it.

[0029] Specifically, this embodiment details the structure of the mounting bracket 2; the mounting base 21 serves as the main body and is detachably fixed to the back of the screen by screws or clips, facilitating installation and maintenance; the guide rod 22 is the core guiding component for achieving linear sliding of the protective plate 3; at least two parallel guide rods 22 form a group, providing a stable and reliable sliding track for each protective plate 3, effectively preventing jamming, tilting, or rotation that may occur during sliding, ensuring smooth and precise operation; allowing users to push the protective plate 3 with only a small amount of force, resulting in a smooth operating feel and a better user experience.

[0030] In this embodiment, as Figure 2-3 As shown, the guide rod 22 includes a rod body 221 and a limiting slider 222. One end of the rod body 221 is fixed to the mounting base 21, and the other end passes through the corresponding protective plate 3 and is slidably connected to it. The limiting slider 222 is located on the end of the rod body 221 that passes through the protective plate 3. A cavity 301 is provided in the protective plate 3 at the location corresponding to the limiting slider 222 for limiting its sliding.

[0031] Specifically, an anti-detachment structure is added based on the above embodiment; the rod 221 provides the main guiding function; the key lies in the cooperation between the limiting slider 222 and the cavity 301. The length of the cavity 301 limits the sliding stroke of the limiting slider 222, thereby strictly limiting the sliding range of the protective plate 3; this ensures that the protective plate 3 will never accidentally fall off the guide rod 22, enhancing the durability and reliability of the product. Especially when there is frequent sliding or the equipment is impacted, this structure can effectively ensure the integrity of the mechanism.

[0032] In some embodiments, such as Figure 1-3 As shown, the limiting structure 4 includes a limiting plug 41, which is located on the side of the protective plate 3 away from the mounting bracket 2. The protective plate 3 has a groove 302 corresponding to the limiting plug 41. The limiting plug 41 can slide longitudinally relative to the protective plate 3 within the groove 302.

[0033] Specifically, this embodiment reveals a basic implementation of the limiting structure 4; the limiting block 41 is the active component for performing locking, which is located on the outside of the protective plate 3 to facilitate cooperation with the terminal body 11 or the folding screen 12; the slide groove 302 allows the limiting block 41 to move longitudinally (perpendicular to the sliding direction of the protective plate) within a certain range, which is the basis for realizing the "locking" and "unlocking" actions; the user can control the locked state by operating the limiting block 41 to slide up and down, which is simple in structure and intuitive in operation.

[0034] In some embodiments, such as Figure 2-3 As shown, a first limiting slot 102 is provided on the terminal body 11 at the corresponding limiting plug 41, so that the limiting plug 41 can be inserted into it to lock after the protective plate 3 slides to the first position; a second limiting slot 103 is provided on the back of the folding screen 12 at the corresponding limiting plug 41, so that the limiting plug 41 can be inserted into it to lock after the protective plate 3 slides to the second position.

[0035] Specifically, this embodiment adds a locking point that cooperates with the limiting plug 41; the first limiting slot 102 and the second limiting slot 103 are precisely opened at the corresponding positions of the terminal body 11 and the folding screen 12, respectively; when the protective plate 3 slides to the first position (covering position), pressing down the limiting plug 41 will allow it to be inserted into the first limiting slot 102, and the protective plate 3 will be firmly locked by the principle of mechanical interlocking, preventing it from sliding open due to vibration or movement, and ensuring the absolute reliability of protection; similarly, in the second position (storage position), the limiting plug 41 is inserted into the second limiting slot 103, which can lock the protective plate 3 in the storage state, keep the back of the device flat, and prevent accidental extension from interfering with operation.

[0036] In some embodiments, such as Figure 4As shown, the limiting structure 4 also includes a sliding member 42, which includes a sliding block 421 and a guide post 422. The sliding block 421 is fixedly disposed on the side wall of the limiting insert 41. The side wall of the sliding groove 302 is provided with a movable groove 303 for longitudinal sliding of the sliding block 421. The guide post 422 is longitudinally connected in the movable groove 303 and passes through the sliding block 421 and is slidably connected to it.

[0037] Specifically, this embodiment optimizes and refines the sliding of the limiting plug 41; the sliding member 42 provides an independent and stable guide for the up and down movement of the limiting plug 41; the cooperation between the sliding block 421 and the guide post 422 ensures that the limiting plug 41 can only perform precise linear movement without swaying or jamming, resulting in a smoother operating feel; the movable groove 303 provides space for the entire sliding member 42 to accommodate and move, making the internal structure compact and orderly, greatly improving the quality and reliability of the limiting operation.

[0038] In this embodiment, as Figure 4 As shown, the slider 42 also includes a spring 423, which is sleeved on the guide post 422 and located on the top of the slider 421, for applying downward pressure to the slider 421.

[0039] Specifically, an automatic reset function is further introduced based on the above embodiments; the spring 423 continuously applies downward pressure to the sliding block 421, thereby also transmitting a downward force to the limiting plug 41; so that in its natural state, the limiting plug 41 always maintains a "tendency to lock" state. When the protective plate 3 slides to the correct position and the limiting plug 41 aligns with the first limiting slot 102 or the second limiting slot 103, it will automatically spring in and lock under the pressure of the spring 423, realizing semi-automatic locking. The user does not need to manually press down, which improves the level of intelligence and convenience; when unlocking, the user only needs to push the limiting plug 41 upward to overcome the spring force.

[0040] In some embodiments, such as Figure 1-2 , Figure 5 As shown, a dual-screen control terminal also includes two toggle blocks 5, which are symmetrically arranged on the top of the two protective plates 3 to assist the sliding of the protective plates 3.

[0041] Specifically, this embodiment adds a user-friendly operation design; the lever 5 protrudes from the top of the protective plate 3, providing the user with a clear point of force application; the user can easily and effortlessly push the protective plate 3 to slide by flicking the lever 5 with their finger, avoiding the slippage or inconvenience that may be caused by directly pushing and pulling the protective plate body, greatly improving the convenience of operation and user experience.

[0042] 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.
