Description

Technical Field

[0001] This utility model belongs to the field of terminal technology, and more specifically, it relates to a floating screen button structure and an intelligent education terminal. Background Technology

[0002] Smart educational terminals, such as walkie-talkies, are widely used in children's education. These terminals typically feature a display screen and buttons. The screen displays relevant information, while the buttons allow users to interact with the device. Generally, there are two interaction design schemes: 1. Touchscreen solution: This uses a full touchscreen for interaction. While it offers display functionality and a simple appearance, it lacks the physical feedback of physical buttons, making it difficult for users to accurately locate objects during blind or rapid operation. Furthermore, prolonged touch use can easily scratch the screen. Additionally, this design requires an extra screen protection layer, increasing cost and structural complexity. 2. Screen and button separation solution: The screen is only used for display, while physical buttons are independently located on the edge of the device (such as the layout in children's walkie-talkies from brands like Jihu, Tongque, and Disney). While this solution retains the tactile feedback of physical buttons, it requires additional space, increasing the product's size and contradicting the miniaturization and lightweight requirements of children's products. Moreover, the lack of a linkage protection mechanism between the buttons and the screen means that frequent button presses may indirectly damage the screen components due to stress transmission.

[0031] Smart educational terminals, such as walkie-talkies, are widely used in children's education. These terminals typically feature a display screen and buttons. The screen displays relevant information, while the buttons allow users to interact with the device. Generally, there are two interaction design schemes: 1. Touchscreen solution: This uses a full touchscreen for interaction. While it offers display functionality and a simple appearance, it lacks the physical feedback of physical buttons, making it difficult for users to accurately locate objects during blind or rapid operation. Furthermore, prolonged touch use can easily scratch the screen. Additionally, this design requires an extra screen protection layer, increasing cost and structural complexity. 2. Screen and button separation solution: The screen is only used for display, while physical buttons are independently located on the edge of the device (such as the layout in children's walkie-talkies from brands like Jihu, Tongque, and Disney). While this solution retains the tactile feedback of physical buttons, it requires additional space, increasing the product's size and contradicting the miniaturization and lightweight requirements of children's products. Moreover, the lack of a linkage protection mechanism between the buttons and the screen means that frequent button presses may indirectly damage the screen components due to stress transmission.

[0032] To alleviate or solve the above technical problems, this utility model proposes a floating screen button structure, including a display module 10, a module support 20, a circuit board 30, and an elastic element 24. The elastic element 24 is located between the module support 20 and the circuit board 30. The display module 10 can be used as a button. When the display module 10 is pressed, the elastic element 24 is compressed, and the module support 20 triggers the switching device 31 on the circuit board 30, thereby enabling the display module 10 to display relevant information after the switching device 31 is triggered. In this way, the display module 10 is floating and can be used as a screen as well as a button, without occupying too much space, while also having the tactile feedback of a mechanical button.

[0033] The floating screen button structure provided in the embodiments of this utility model will now be described.

[0034] Please refer to the following: Figures 1 to 3 The floating screen button structure includes:

[0035] Display module 10;

[0036] The module bracket 20 is used to fix the display module 10. The module bracket 20 has a pressing part 21 and a limiting part 22 for limiting the movement of the display module 10 on the side facing away from the display module 10.

[0037] Circuit board 30, display module 10 is electrically connected to circuit board 30, switch device 31 is fixed on circuit board 30 and electrically connected to it, and pressing part 21 is used to press and trigger switch device 31;

[0038] The elastic element 24 is disposed between the module bracket 20 and the circuit board 30.

[0039] Display module 10 can be LCD, OLED, etc., and can be connected to circuit board 30 to display interactive information. The specific type of display module 10 is not limited here.

[0040] The module bracket 20 is the mounting structure for the display module 10. The display module 10 is fixed on the module bracket 20. The module bracket 20 can be a one-piece structure or a multi-piece structure. One side of the module bracket 20 has a mounting surface for mounting and fixing the display module 10. The other side of the module bracket 20 has a pressing part 21 and a limiting part 22. The pressing part 21 is used to press the trigger switch device 31, and the limiting part 22 is used to limit the movement of the display module 10 to prevent the display module 10 from being damaged due to excessive movement, or the circuit board 30 from being pressed and damaged.

[0041] Circuit board 30 includes integrated circuits, connectors, etc., with the connectors used for connecting to other electronic devices. Circuit board 30 also has a switch 31; when the switch 31 is triggered, a trigger signal is transmitted to circuit board 30, which then controls other electronic devices to provide corresponding feedback. Display module 10 is electrically connected to circuit board 30. Generally, display module 10 has an FPC (Flexible Printed Circuit), and the connectors on the FPC are interconnected with the connectors on circuit board 30.

[0042] The elastic element 24 is a deformable telescopic structure, which is disposed between the module bracket 20 and the circuit board 30.

[0043] Since the display module 10 is fixed on the module bracket 20, and there is an elastic element 24 between the module bracket 20 and the circuit board 30, the display module 10 can be understood as being floating and pressable. When the display module 10 is pressed, the module bracket 20 moves synchronously, the pressing part 21 of the module bracket 20 presses the trigger switch device 31, and the limiting part 22 can limit the pressing distance of the display module 10. When the external force pressing the display module 10 disappears, the rebound force of the elastic element 24 restores the display module 10 and the module bracket 20 to their original positions.

[0044] The display module 10 can be pressed as a whole, serving not only as a screen but also as a button. It has the tactile feel of a mechanical button, which is beneficial for users to perform blind or quick operations. Moreover, it does not require additional buttons and occupies less physical space, making the product more compact and lightweight.

[0045] The floating screen button structure in the above embodiment includes a display module 10, a module support 20, a circuit board 30 with a switching device 31, and an elastic member 24 located between the module support 20 and the circuit board 30. The display module 10 is fixed to the module support 20, and the module support 20 has a limiting part 22 and a pressing part 21. In this way, the display module 10 can be pressed as a whole, without the need to set buttons and screen separately, and it also has the pressing and rebound feel of a mechanical button.

[0046] Please refer to some embodiments of this utility model. Figure 2 A first buffer 40 is provided between the circuit board 30 and the limiting part 22. The first buffer 40 can be pressed and deformed. When the display module 10 is pressed, the distance between the module support 20 and the circuit board 30 is shortened, the elastic member 24 is compressed, and the first buffer 40 is also compressed. When the first buffer 40 is compressed to its limit, the display module 10 can no longer be pressed.

[0047] Because a first buffer 40 is provided between the circuit board 30 and the limiting part 22, when the user presses the display module 10, they can press a position directly opposite or adjacent to the pressing part 21, a position directly opposite or adjacent to the limiting part 22, or other positions. Pressing the display module 10 at a position directly opposite the pressing part 21 allows the pressing part 21 to directly trigger the switching device 31; pressing the display module 10 at other positions allows the switching device 31 to be triggered indirectly through the pressing part 21 via a lever action. Moreover, when the external force pressing the display module 10 disappears, the elastic member 24 and the first buffer 40 simultaneously provide a rebound force, causing the display module 10 and the module support 20 to quickly return to their initial positions.

[0048] In some embodiments, the elastic element 24 and the first buffer element 40 may both be structural elements such as springs.

[0049] Please refer to some embodiments of this utility model. Figure 2 The first buffer 40 is an insulating component. The insulating component is located between the limiting part 22 and the circuit board 30 and has an insulating function to prevent short circuits.

[0050] In some embodiments, the first buffer 40 is a silicone part, a rubber part, etc.

[0051] In some embodiments, the first buffer 40 is a buffer pad, which may be bowl-shaped and covers the end of the limiting portion 22 away from the module support 20, and is disposed between the limiting portion 22 and the circuit board 30. In this way, the end of the limiting portion 22 away from the module support 20 can be blocked and isolated, reducing the possibility of the circuit board 30 contacting the limiting portion 22.

[0052] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The limiting part 22 extends from the module bracket 20 on the side facing away from the display module 10, and the elastic member 24 is sleeved on the outer periphery of the limiting part 22. One end of the elastic member 24 abuts against the circuit board 30, and the other end of the elastic member 24 can abut against the step on the surface of the limiting part 22 or against the module bracket 20.

[0053] In some embodiments, the limiting portion 22 is elongated to facilitate the elastic member 24 being fitted onto the outer periphery of the limiting portion 22. The cross-section of the limiting portion 22 may be circular, cross-shaped, or other structures, and its cross-sectional shape is not limited here.

[0054] In some embodiments, the first buffer 40 is bowl-shaped, with the opening of the first buffer 40 facing the module support 20, and one end of the elastic member 24 extends into the interior of the first buffer 40 through the opening. In this way, the first buffer 40 can limit the elastic member 24.

[0055] In other embodiments, the elastic element 24 may also be installed in other locations, as long as it allows the display module 10 to float up and down.

[0056] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The pressing part 21 is located in the middle of the module support 20, and the limiting parts 22 are multiple and arranged around the pressing part 21. That is to say, the switch device 31 is located in the middle, and the limiting parts 22 are arranged around the switch device 31. In this way, no matter where the display module 10 is pressed, the switch device 31 can be touched by lever action, which is convenient for user operation.

[0057] In some embodiments, the number of limiting portions 22 is four, five, six, etc.

[0058] Please refer to some embodiments of this utility model. Figure 5 The pressing part 21 has an annular rib 23 around its periphery. The annular rib 23 extends from the module bracket 20 on the side facing away from the display module 10 and is located on the outer periphery of the switching device 31. The annular rib 23 is arranged in a ring shape, and after the module bracket 20 is installed, the annular rib 23 surrounds the outer periphery of the switching device 31. Correspondingly, the pressing part 21 is located inside the annular rib 23. The bottom end of the switching device 31 is fixed to the circuit board 30, the top end of the switching device 31 is the trigger part, and the annular rib 23 surrounds the circumferential sidewall of the switching device 31.

[0059] The ring-shaped rib 23 can protect the outer periphery of the switching device 31 and can also be used to initially position the module bracket 20 during installation to avoid misalignment during installation.

[0060] In some embodiments, the annular bone position 23 is a closed annular structure. Alternatively, the annular bone position 23 includes a plurality of annular units spaced apart circumferentially.

[0061] In some embodiments, the pressing part 21 is a raised bone position, which can more easily trigger the switching device 31 when the display module 10 is pressed, thus avoiding the phenomenon of button malfunction.

[0062] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The switching device 31 is covered with a switch sleeve 32 made of insulating material, and the pressing part 21 is used to contact the switch sleeve 32. The switch sleeve 32 can completely cover the surface of the switching device 31, or partially cover the surface of the switching device 31. When the pressing part 21 is pressed down, the pressing part 21 directly contacts the switch sleeve 32 and does not directly contact the switching device 31.

[0063] By setting an insulating switch sleeve 32, firstly, it can prevent short circuits; secondly, it can protect the switching device 31; and thirdly, it can isolate the pressing part 21 from the switching device 31, so that no abnormal noise is produced when pressing, and the pressing feel is improved.

[0064] In some embodiments, the switch sleeve 32 is a silicone sleeve, a rubber sleeve, etc.

[0065] Please refer to some embodiments of this utility model. Figures 3 to 5 The floating screen button structure also includes a housing structure 50, to which the circuit board 30 is fixed. At least a portion of the housing structure 50 is located on the outer periphery of the module bracket 20. The module bracket 20 extends toward the housing structure 50 and forms a protruding structure 25. The inner wall of the housing structure 50 has a limiting step 511, and the protruding structure 25 abuts against the limiting step 511 under the action of the elastic member 24. When the module bracket 20 and the display module 10 are installed on the housing structure 50, the module bracket 20 and the display module 10 can float relative to the housing structure 50, and the housing structure 50 can enclose the periphery of the module bracket 20 and the display module 10. When the display module 10 is pressed, the display module 10 moves toward the circuit board 30, and the protruding structure 25 and the limiting step 511 separate from each other; when the pressing force disappears, the display module 10 and the module bracket 20 move away from the circuit board 30, and the protruding structure 25 and the limiting step 511 abut against each other.

[0066] By setting a protruding structure 25 on the module bracket 20 and a limiting step 511 on the outer shell structure 50, the display module 10 is less likely to shake or make abnormal noises when it is not pressed.

[0067] In some embodiments, the protruding structure 25 and the limiting step 511 abut against each other in the pressing direction, that is, the contact surface between the protruding structure 25 and the limiting step 511 is perpendicular to the pressing direction.

[0068] In some embodiments, the contact direction between the protruding structure 25 and the limiting step 511 is set at an acute angle to the pressing direction, that is, the contact surface between the protruding structure 25 and the limiting step 511 is set at an acute angle to the pressing direction.

[0069] In some embodiments, the number of protrusions 25 is multiple, and they are arranged around the edge of the screen bracket. This makes the contact between the screen bracket and the housing structure 50 more stable.

[0070] Optionally, the raised structure 25 is formed by the module support 20 extending in a direction perpendicular to the pressing direction.

[0071] In some embodiments, the housing structure 50 includes a middle frame 51 and a bottom shell 52. The middle frame 51 is disposed on the outer periphery of the module bracket 20, a limiting step 511 is disposed on the middle frame 51, and the circuit board 30 is fixed to the bottom shell 52.

[0072] Please refer to some embodiments of this utility model. Figure 3 A lens 60 is mounted on the display module 10. The lens 60 is snapped into the module bracket 20, and a second buffer 61 is provided between the lens 60 and the display module 10. The lens 60 protects the display module 10, and the second buffer 61 is provided between the lens 60 and the display module 10. After the lens 60, the display module 10, and the second buffer 61 are installed, they form an independent mounting assembly, which is then installed onto the housing structure 50.

[0073] The lens 60 protects the display module 10 from scratches and damage caused by repeated pressing. The second buffer 61 ensures a soft contact between the lens 60 and the display module 10 and seals the gap between them.

[0074] In some embodiments, the second buffer 61 is foam.

[0075] This utility model also provides an intelligent education terminal, which includes the floating screen button structure of any of the above embodiments. The intelligent education terminal can be a walkie-talkie, a story machine, etc.

[0076] The intelligent education terminal provided by this utility model adopts the aforementioned floating screen button structure. The floating screen button structure includes a display module 10, a module support 20, a circuit board 30 with a switching device 31, and an elastic member 24 located between the module support 20 and the circuit board 30. The display module 10 is fixed to the module support 20, and the module support 20 has a limiting part 22 and a pressing part 21. Thus, the display module 10 can be pressed as a whole, eliminating the need for separate buttons and a screen, and also providing the tactile feedback of a mechanical button.
