Technical Field

[0001] This utility model relates to the field of button technology, and in particular to an analog button push plate structure, an earphone compartment, and a terminal device. Background Technology

[0002] In modern electronic devices, button structures are one of the important components for user input. With the miniaturization and multi-functionality of electronic devices, traditional mechanical button structures have gradually revealed some problems.

[0003] For example, headphones typically have buttons used for pairing, resetting, or checking battery level. These buttons usually include a button cap, a base, a spring or microswitch, and a circuit board, which is electrically connected to the main control circuit board. This same structure is also used in some terminal devices.

[0004] The above structure has the following main technical problems when in use: high material cost, requiring additional circuit boards; and complex operation, requiring additional circuit boards to be soldered to the main circuit board.

[0005] Therefore, improvements are needed. Utility Model Content

[0006] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a simulated button push plate structure to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a simulated button push plate structure, comprising: a housing, the housing having at least one side wall; a locking member, the locking member being disposed on the side wall; the locking member having a protrusion relative to the side wall and an extension connected to the protrusion, the protrusion protruding relative to the end face of the side wall; a main PCB board, the main PCB board having contacts, the contacts being disposed at the position of the extension; wherein, the protrusion is pressed by an external force; under the limitation of the locking member by the side wall, the extension triggers the contacts on the main PCB board.

[0008] Furthermore, the card is vertically mounted on the side wall, and the protrusion and the extension are vertically distributed; the contact on the main PCB board is arranged in the direction of movement of the extension, so that the movement of the extension triggers the contact.

[0009] Furthermore, the card is mounted laterally on the side wall, and the protrusion and the extension are laterally distributed; the contacts on the main PCB are arranged in the direction of movement of the extension, so that the movement of the extension triggers the contacts.

[0010] Furthermore, the protrusion and the extension are an integral structure.

[0011] Furthermore, the side wall is provided with a slot for embedding the card, and the slot is provided with a hollow area for the protrusion to protrude.

[0012] Furthermore, the card slot is provided with one or more hollowed-out limiting areas, and the card is provided with a limiting strip that cooperates and is fixed with the limiting area. The limiting strip is movable relative to the card. When the card is placed in the card slot and moves to a designated position, the limiting strip protrudes and is locked in the limiting area.

[0013] Furthermore, the card has an upwardly protruding guide portion relative to the hollow area. When the card is slidably embedded in the card slot, the guide portion slides and guides along the hollow area.

[0014] Furthermore, it includes a button, which is disposed at the protrusion; the button is pressed by an external force, and the deformation of the protrusion drives the extension to trigger the contact.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In view of the technical problems described in the background art, such as Figure 1-12As shown, a pusher structure for a simulated button 13 is provided, comprising: a housing 1, the housing 1 having at least one side wall 2; a locking member 3, the locking member 3 being disposed on the side wall 2; the locking member 3 having a protrusion 4 relative to the side wall 2 and an extension 5 connected to the protrusion 4, the protrusion 4 protruding relative to the end face of the side wall 2; a main PCB board 6, the main PCB board 6 having a contact 7, the contact 7 being disposed at the position of the extension 5; wherein, the protrusion 4 is pressed by an external force; under the limitation of the locking member 3 by the side wall 2, the extension 5 triggers the contact 7 on the main PCB board 6.

[0038] To facilitate understanding of the above technical solution, the following description uses the structure of a traditional earphone charging case 14. A traditional earphone charging case 14 typically has a physical button 13. This physical button 13 includes a button cap, a base, a spring or microswitch, and a circuit board. A separate circuit board is used to implement the functions of this physical button 13, which may include pairing mode, volume control, earphone reset, and battery level monitoring. The usage process is as follows: pressing the physical button 13 under external force triggers the microswitch to execute the corresponding function.

[0039] In the above technical solution, the simulated button 13 push plate structure includes a housing 1, a card 3, and a main PCB board 6.

[0040] The housing 1 can be constructed as the outer shell or inner shell of a device, wherein the device can be an earphone compartment 14, a tablet, a mobile phone, or other structures. The side wall 2 on the housing 1 serves as a mounting base, wherein the side wall 2 can limit the extension 5 of the clip 3, allowing it to move toward the contact point 7.

[0041] The mounting position of the clip 3 is located on the side wall 2 of the housing 1. In practice, the clip 3 can be a separate component or it can be integrated with the housing 1. (Refer to...) Figure 12 The clip 3 mainly includes a protrusion 4 and an extension 5. The protrusion 4 is an upwardly protruding sheet structure, and the extension 5 is a sheet structure connected to the protrusion 4. Preferably, the protrusion 4 and the extension 5 are an integral structure.

[0042] The main PCB board 6 is the main control board of the device. By adding contacts 7 to the main PCB board 6, the contacts 7 can be microswitches or spring contacts, etc. This concentrates the original PCB board into the main PCB board 6, effectively reducing the number of PCB boards and the connection operations between the PCB boards and the main PCB board 6.

[0043] In practical use, manual pressure is applied to the protrusion 4, which deforms and moves the extension 5. The extension 5 then triggers the contact 7 on the main PCB board 6 to perform the corresponding function.

[0044] This invention simplifies the overall structure and reduces material and assembly costs by directly mounting the card 3 onto the side wall 2 of the housing 1 and triggering the contact 7 on the main PCB board 6 through the extension 5 of the card 3. This eliminates the need for additional circuit boards and complex soldering operations in the traditional button 13 structure. The design of the protrusion 4 and extension 5 of the card 3 allows the user to simply press the protrusion 4 to drive the extension 5 to trigger the contact 7 on the main PCB board 6, making the operation simple and intuitive.

[0045] refer to Figure 3-8 As shown, the card 3 is vertically mounted on the side wall 2, and the protrusion 4 and the extension 5 are vertically distributed; the contact 7 on the main PCB board 6 is arranged in the direction of movement of the extension 5 so that the extension 5 moves to trigger the contact 7.

[0046] As an implementable structure, specifically, the card 3 is set vertically. When the card 3 is set vertically, the main PCB board 6 is installed above or below the card 3. The driving process is as follows: when the protrusion 4 is pressed under the action of external force, the extension 5 moves in the vertical direction to trigger the contact 7 and execute the corresponding function.

[0047] The card 3 is horizontally mounted on the side wall 2, and the protrusion 4 and the extension 5 are horizontally distributed; the contact 7 on the main PCB board 6 is arranged in the direction of movement of the extension 5 so that the extension 5 moves to trigger the contact 7.

[0048] In another possible configuration, specifically, the card 3 is positioned horizontally. When the card 3 is positioned horizontally, the main PCB board 6 is installed to the left or right of the card 3. The driving process is as follows: when the protrusion 4 is pressed under the action of external force, the extension 5 moves in the horizontal direction to trigger the contact 7 and execute the corresponding function.

[0049] Of course, during implementation, the choice can be made according to the actual implementation needs, such as oblique direction, and there are no restrictions on this.

[0050] like Figure 5-6 As shown, the side wall 2 is provided with a slot 8 for embedding the card 3, and the slot 8 is provided with a hollow area 9 for the protrusion 4 to protrude.

[0051] To facilitate the installation and fixation of the clip 3, a slot 8 can be provided on the side wall 2. During the installation process of the clip 3, the clip 3 is inserted into the slot 8. At the same time, the structure of the protrusion 4 is exposed in the hollow area 9, which facilitates the application of external pressure.

[0052] As shown in the figure, the slot 8 is provided with one or more hollowed-out limiting areas 10, and the card piece 3 is provided with a limiting strip 11 that cooperates and is fixed with the limiting area 10. The limiting strip 11 is movable relative to the card piece 3. When the card piece 3 is placed in the slot 8 and moves to a designated position, the limiting strip 11 protrudes and is locked in the limiting area 10.

[0053] To achieve the installation and positioning of the card 3, a limiting area 10 is provided on the card slot 8. In this embodiment, limiting areas 10 are provided on both sides of the card slot 8, although other numbers of limiting areas 10 may also be used, which will not be elaborated further. A limiting strip 11 is provided on the card 3 at the corresponding position of the limiting area 10, and the limiting strip 11 is raised relative to the card 3. The installation process of the card 3 is as follows: when the card 3 is inserted into the card slot 8, the limiting strip 11 is pressed into the card slot 8 under the action of the card slot 8. As the card 3 moves further, when the limiting strip 11 moves to the position of the limiting area 10, the limiting strip 11 springs up and abuts against the edge of the limiting area 10 to achieve fixation.

[0054] As shown in the figure, the card 3 has an upwardly protruding guide portion 12 relative to the hollow area 9. When the card 3 is slidably embedded in the card slot 8, the guide portion 12 slides and guides along the hollow area 9.

[0055] In order to guide and coordinate the positioning of the card 3, a guide part 12 is provided on the card 3. In practice, the hollow area 9 is a U-shaped hollow area 9 region. The guide part 12 is a U-shaped guide part 12 corresponding to the hollow area 9 region. When the card 3 is inserted into the card slot 8, the guide part 12 abuts against the outline edge of the hollow area 9 until the guide part 12 is completely in contact with the outline of the hollow area 9. At this time, the card 3 moves into place, and the limiting strip 11 pops out and abuts against the limiting area 10.

[0056] like Figure 1 and 2 As shown, it includes a button 13, which is located at the protrusion 4; when the button 13 is pressed by an external force, the protrusion 4 deforms and drives the extension 5 to trigger the contact 7.

[0057] In implementation, a button 13 can be added. The button 13 can be an integral structure with the protrusion 4 or the button 13 can be an independent component set at the position of the protrusion 4. Preferably, in this embodiment, the button 13 is an independent component set at the position of the protrusion 4. For example, taking the earphone compartment 14 as an example, the button 13 is exposed on the outer surface of the shell 1 of the earphone compartment 14. When pressed by the user, it drives the protrusion 4 to deform and move to the contact 7 on the main PCB board 6 to execute the preset function.

[0058] refer to Figure 9-11An earphone charging case 14 includes the analog button 13 pusher plate structure described in the above-mentioned technical solution. In application scenarios, the analog button 13 pusher plate structure can be implemented on the earphone charging case 14 to replace the traditional button 13 structure that requires a PCB board, thereby reducing production and installation costs.

[0059] A terminal device includes the simulated button 13 push-plate structure described in the above-mentioned technical solution. In application scenarios, this extends to buttons 13 that use independent PCB boards, such as tablets and mobile phones, where independent PCB boards are typically placed at the button 13 position. This invention provides a simulated button 13 push-plate structure to replace the traditional button 13 structure that requires a PCB board, thereby reducing production and installation costs.

[0060] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
