[0002] A button-concealed LCD screen integrates physical operation buttons within the screen structure using mechanical or electronic means. This design retains the reliability of physical button operation while significantly improving the screen's integrated aesthetics and environmental adaptability.

[0003] Button-concealed LCD displays are mainly used in industrial control, outdoor equipment, medical instruments, and other scenarios with high requirements for space utilization and protection. However, this concealed design also brings new challenges: since the button body is hidden inside the screen, users cannot intuitively confirm whether the button has been successfully triggered during operation, which may affect the convenience and accuracy of operation. In addition, users may press the button for a long time or with great force when they are unsure of the button status, thereby increasing the risk of damage to the button mechanism.

[0004] Therefore, there is a need to provide a hidden LCD screen with a feedback mechanism. Utility Model Content

[0005] To overcome the drawbacks of hidden buttons, where the buttons are concealed inside the screen, making it difficult for users to visually confirm whether a button has been successfully triggered, which may affect the convenience and accuracy of operation, and also increasing the risk of damage to the button mechanism due to users pressing the button for an extended period or with excessive force when unsure of its status, this invention provides a button-concealed LCD display with a feedback mechanism.

[0006] This utility model provides the following technical solution: a button-concealed LCD display screen, including a mounting frame, a display screen, a mounting plate, and button bodies. The display screen is embedded inside the mounting frame. A mounting groove is opened on the front right side of the mounting frame. The mounting plate is rotatably mounted inside the mounting groove. Multiple button bodies are mounted on the mounting plate. The button bodies are electrically connected to the display screen. It also includes a mounting bracket, a pressing rod, a pressing plate, an elastic element, and a feedback button. The mounting bracket is installed inside the mounting groove. Multiple pressing rods are slidably mounted on the mounting bracket. The pressing plate is fixedly connected to the rear end of the pressing rod. The pressing plate can press the button body. An elastic element is sleeved on the pressing rod. The two ends of the elastic element are respectively connected to the mounting bracket and the pressing rod. Multiple feedback buttons are mounted on the mounting bracket. The feedback buttons are electrically connected to the button bodies.

[0007] Furthermore, it also includes a connecting frame, a rotating rod, and a connecting block. The connecting frame is fixedly connected to the outside of the mounting plate, and the rotating rod is fixedly connected to both ends of the connecting frame. The connecting block is fixedly connected to the rotating rod on the right side, and the connecting block is rotatably connected to the mounting frame.

[0008] Furthermore, it also includes a rotating plate, which is fixedly connected to the connecting block.

[0009] Furthermore, it also includes a seal, with a seal installed inside the mounting groove.

[0010] Furthermore, multiple miniature heat dissipation holes are provided on the back of the mounting plate.

[0011] Furthermore, the surface of the rotating plate is provided with an anti-slip coating.

[0012] Compared with the prior art, the present invention provides a button-hidden LCD display screen, which has the following advantages: 1. The movement of the pressing plate will trigger the feedback key, which transmits the operation status signal of the button body to the display screen to further confirm whether the operation is successful. This design improves the convenience of operation and avoids the risk of device damage caused by users pressing the button for a long time.

[0013] 2. Twist the rotating plate to misalign the button body with the pressing plate. Once the button body and the pressing plate are misaligned, even if the squeezing rod is accidentally touched, the button function will not be triggered, thus effectively preventing accidental operation.

Detailed Implementation

[0020] 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.

[0021] Example 1: A button-concealed LCD display screen, please refer to... Figures 1-5 The device includes a mounting frame 1, a display screen 2, a mounting plate 3, and button bodies 4. The display screen 2 is embedded inside the mounting frame 1. A mounting groove 201 is provided on the front right side of the mounting frame 1. The mounting plate 3 is rotatably mounted inside the mounting groove 201. Four button bodies 4 are mounted on the mounting plate 3. The button bodies 4 are electrically connected to the display screen 2. A mounting bracket 5 is installed inside the mounting groove 201. Four pressing rods 6 are slidably mounted on the mounting bracket 5. A pressing plate 7 is fixedly connected to the rear end of the pressing rods 6. The pressing plate 7 can press the button bodies 4. An elastic element 8 is sleeved on the pressing rods 6. The two ends of the elastic element 8 are connected to the mounting bracket 5 and the pressing rods 6, respectively. Four feedback buttons 9 are provided on the mounting bracket 5. The feedback buttons 9 are electrically connected to the button bodies 4. A sealing element 14 is provided inside the mounting groove 201 to ensure that dust or water droplets do not enter the mounting groove 201, providing effective protection for the button bodies 4. Several micro heat dissipation holes are provided on the back of the mounting plate 3 to dissipate heat accumulated in the button area and prevent high temperature from causing contact oxidation.

[0022] In its initial state, the mounting plate 3 is hidden inside the mounting slot 201, the button body 4 is not exposed, and the surface of the display screen 2 remains simple, ensuring the integrity and aesthetics of the device's appearance. When the user needs to use the button, they can press the squeezing rod 6. The squeezing rod 6 moves backward, causing the pressing plate 7 to move backward, thus squeezing the button body 4 and triggering the button's function. During this process, the movement of the pressing plate 7 also triggers the feedback button 9, which transmits the operation status signal of the button body 4 to the display screen 2 to further confirm whether the operation was successful. This design improves the convenience of operation and avoids the risk of device damage caused by users pressing the button for a long time. During the pressing process, the elastic element 8 is compressed. When the user releases the squeezing rod 6, the elastic element 8 pushes the squeezing rod 6 and the pressing plate 7 forward to reset through the rebound force.

[0023] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 2 , Figure 4 and Figure 5A connecting frame 10 is fixedly connected to the outside of the mounting plate 3. Rotating rods 11 are fixedly connected to both ends of the connecting frame 10. A connecting block 12 is fixedly connected to the rotating rod 11 on the right side. The connecting block 12 is rotatably connected to the mounting frame 1. A rotating plate 13 is fixedly connected to the connecting block 12. The rotating plate 13 is used to increase the force points and facilitate the rotation of the connecting block 12. The surface of the rotating plate 13 is provided with an anti-slip coating to increase the friction coefficient and prevent slippage.

[0024] When the button is not needed, turn the rotating plate 13, which will drive the mounting plate 3 to rotate through the connecting block 12, and adjust the position of the button body 4 so that the button body 4 is misaligned with the pressing plate 7. When the button body 4 is misaligned with the pressing plate 7, even if the squeezing rod 6 is accidentally touched, the button function will not be triggered, thus effectively preventing accidental operation.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
