[0026] The following is in conjunction with the appendix Figures 1 to 10 This application describes the electronic device 10 provided in an embodiment.

[0027] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, in some embodiments of this application, an electronic device 10 is provided, including: a frame 100, the frame 100 having an opening 110 and a channel 1100; a bracket 200 disposed in the channel 1100; a flexible circuit board 300 disposed in the channel 1100, the flexible circuit board 300 having a switch 310, the channel 1100 connecting the opening 110 and the switch 310; and a first sealing member 500 disposed in the bracket 200, the first sealing member 500 abutting against the frame 100 to block the channel 1100.

[0028] In this embodiment, the electronic device 10 includes a frame, a bracket 200, a flexible circuit board 300, and a first sealing element 500.

[0029] The frame 100 has an opening 110, meaning there is an opening 110 on the outer surface of the frame 100. The frame 100 also has a channel 1100, which connects to the opening 110 and also connects to the switch 310. The opening 110 and the switch 310 are connected through the channel 1100. Optionally, components of the electronic device 10 are installed within the channel 1100. The button 400 of the electronic device 10 is located at the opening 110.

[0030] The bracket 200 is located in the channel 1100, and the frame 100 serves as the mounting carrier for the bracket 200, and has the function of installing and fixing the bracket 200.

[0031] The flexible circuit board 300 is located in the channel 1100. The flexible circuit board 300 is equipped with a switch 310. The bracket 200 has the function of installing and fixing the flexible circuit board 300, which can ensure the matching size between the flexible circuit board 300 and the opening 110, thereby ensuring the matching size between the switch 310 and the opening 110.

[0032] The first sealing element 500 is provided on the bracket 200. The first sealing element 500 abuts against the frame 100 to block the channel 1100. That is, the first sealing element 500 cooperates with the frame 100 to disconnect the connection between the opening 110 and the switch 310.

[0033] This design, while ensuring the functionality of the electronic device 10, blocks the channel 1100 connecting the opening 110 to the switch 310. This prevents moisture, dirt, and other impurities from the external environment from entering the switch 310 of the flexible circuit board 300 through the opening 110. This ensures the tactile feedback of the trigger button 400, extends the lifespan of both the flexible circuit board 300 and the button 400, and improves the product's performance and market competitiveness.

[0034] Optionally, switch 310 is a micro switch.

[0035] Optionally, the electronic device 10 may be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop computer, a mobile computer, an augmented reality device (also known as an AR device), a virtual reality device (also known as a VR device), and a handheld game console, etc.

[0036] In some embodiments of this application, such as Figure 1 , Figure 3 , Figure 4 and Figure 8As shown, the electronic device 10 also includes: a button 400 located at the opening 110, the button 400 being movably connected to the bracket 200; the button 400 having a hanging foot 410 and a striking post 420, the bracket 200 having a suspension part 210, the hanging foot 410 being hung on the suspension part 210, and the striking post 420 being disposed opposite to the switch 310.

[0037] In this embodiment of the application, the structure of the electronic device 10 is further defined.

[0038] The electronic device 10 also includes a button 400, which is located at the opening 110 and is movably connected to the bracket 200. The button 400 is movable relative to the bracket 200.

[0039] Specifically, pressing button 400 causes button 400 to move relative to bracket 200, thereby triggering switch 310 of flexible circuit board 300 to perform operations such as powering on electronic device 10, locking screen, and adjusting volume.

[0040] Specifically, the button 400 has a hanging foot 410. The bracket 200 has a hanging part 210. The hanging part 210 cooperates with the hanging foot 410, wherein the hanging foot 410 is hung on the hanging part 210. This prevents the button 400 from detaching from the frame 100 and ensures the mating dimensions between the button 400 and the frame 100. This allows the button 400 to be triggered, and the button 400 can correspondingly trigger the switch 310 on the flexible circuit board 300.

[0041] Furthermore, the button 400 also has an actuating post 420, which is positioned opposite to the switch 310 on the flexible circuit board 300. The actuating post 420 is used to trigger the switch 310. That is, when the button 400 is pressed, the button 400 moves relative to the bracket 200, and the actuating post 420 triggers the switch 310 of the flexible circuit board 300, enabling operations such as powering on the electronic device 10, locking the screen, and adjusting the volume.

[0042] Optionally, button 400 has a strike post 420.

[0043] Optionally, the button 400 has a plurality of striking posts 420, each striking post 420 being disposed opposite to a switch 310.

[0044] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, the first sealing element 500 includes a first sealing part 510, the frame 100 is provided with a first boss 120, the first sealing part 510 abuts against the first boss 120, and at least a portion of the first boss 120 is located between the hanging foot 410 and the striking post 420.

[0045] In this embodiment, the mating structure of the first seal 500, bracket 200, frame 100 and button 400 is further defined.

[0046] Specifically, the first seal 500 is provided on the bracket 200, the striking post 420 is located on the periphery of the hanging foot 410, the first seal 500 includes a first sealing part 510, and the frame 100 is provided with a first boss 120.

[0047] The first sealing part 510 mates with the first boss 120, specifically, the first sealing part 510 abuts against the first boss 120. At least a portion of the first boss 120 is located between the hanging foot 410 and the striking post 420. The first sealing member 500 mates with the frame 100 to block dust from entering the hanging foot 410 of the button 400 through the gap between the opening 110 and the button 400, and then flowing into the dust ingress path of the switch 310. This prevents moisture, dirt, and other impurities from the external environment from entering the switch 310 of the flexible circuit board 300 through the channel 1100 connecting the opening 110 and the switch 310. This ensures the tactile feedback of the trigger button 400, helps extend the service life of the flexible circuit board 300 and the button 400, and improves the product's performance and market competitiveness.

[0048] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, there are multiple first sealing parts 510 and multiple first bosses 120, with each first sealing part 510 abutting against a first boss 120; wherein, multiple first sealing parts 510 are arranged at intervals on the outside of the hanging foot 410.

[0049] In this embodiment, the number of the first sealing part 510 and the first boss 120 and their mating structure are further defined.

[0050] Specifically, there are multiple first sealing portions 510 and multiple first protrusions 120. That is, there are multiple first sealing portions 510 and multiple first protrusions 120, and each first sealing portion 510 abuts against one first protrusion 120.

[0051] In this arrangement, multiple first sealing portions 510 are arranged at intervals along the circumference of the hanging foot 410, and multiple first protrusions 120 are arranged at intervals along the circumference of the hanging foot 410. That is, multiple first sealing portions 510 are arranged at intervals on the outer side of the hanging foot 410.

[0052] This design increases the mating area between the first seal 500 and the frame 100, and increases the mating angle between the first seal 500 and the frame 100. It can block the channel 1100 from the opening 110 to the switch 310 from multiple directions and angles, effectively preventing moisture, dirt and other impurities in the external environment from entering the switch 310 of the flexible circuit board 300.

[0053] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 4 , Figure 8 , Figure 9 and Figure 10 As shown, the hanging foot 410 includes multiple hanging parts 412, which surround the outside of the striking post 420; the first sealing member 500 includes a second sealing part 520 and a third sealing part 530, and the frame 100 is provided with a second boss 130 and a third boss 140. The second sealing part 520 and the second boss 130 abut each other, and the third sealing part 530 and the third boss 140 abut each other; at least a portion of the second boss 130 is located between the hanging part 412 and the striking post 420; the third boss 140 is located on the side of the hanging foot 410 away from the striking post 420.

[0054] In this embodiment, the mating structure of the first seal 500, bracket 200, frame 100 and button 400 is further defined.

[0055] Specifically, the first sealing element 500 is provided on the bracket 200, the hanging foot 410 includes a plurality of hanging parts 412, and when the plurality of hanging parts 412 are arranged at intervals around the impact post 420, the first sealing element 500 includes a second sealing part 520 and a third sealing part 530, and the frame 100 is provided with a second boss 130 and a third boss 140.

[0056] The second sealing part 520 mates with the second boss 130, and the third sealing part 530 mates with the third boss 140. Specifically, the second sealing part 520 abuts against the second boss 130, and the third sealing part 530 abuts against the third boss 140. The first sealing member 500 mates with the frame 100 to block dust from entering the hanging foot 410 of the button 400 through the gap between the opening 110 and the button 400, and then flowing into the dust ingress path of the switch 310. This prevents moisture, dirt, and other impurities from the external environment from entering the switch 310 of the flexible circuit board 300 through the aforementioned path. This ensures the tactile feedback of the button 400, helps extend the service life of the flexible circuit board 300 and the button 400, and improves the product's performance and market competitiveness.

[0057] In this embodiment, there are two buttons 400, and the two buttons 400 have different structures. One of the buttons 400 includes a striking post 420 and a hanging foot 410. The striking post 420 is located on the periphery of the hanging foot 410. The first sealing member 500 includes a plurality of first sealing parts 510. The frame 100 is provided with a plurality of first protrusions 120. Each first sealing part 510 abuts against a first protrusion 120.

At least a portion of the first protrusions 120 is located between the hanging foot 410 and the striking post 420. Another button 400 includes a striking post 420 and a hanging foot 410. The hanging foot 410 includes multiple hanging parts 412, which surround the outside of the striking post 420. The first seal 500 includes a second sealing part 520 and a third sealing part 530. The frame 100 is provided with a second boss 130 and a third boss 140. The second sealing part 520 and the second boss 130 abut against each other, and the third sealing part 530 and the third boss 140 abut against each other. At least a portion of the second boss 130 is located between the hanging part 412 and the striking post 420, and the third boss 140 is located on the side of the hanging foot 410 away from the striking post 420.

[0058] In other embodiments, there are multiple buttons 400, and any two buttons 400 have the same structure. Each button 400 includes a striking post 420 and a hanging foot 410. The striking post 420 is located around the hanging foot 410. The first seal 500 includes multiple first sealing portions 510. The frame 100 is provided with multiple first protrusions 120. Each first sealing portion 510 abuts against a first protrusion 120. The multiple first sealing portions 510 are spaced apart on the outside of the hanging foot 410. At least a portion of the first protrusions 120 is located between the hanging foot 410 and the striking post 420.

[0059] In some other embodiments, there are multiple buttons 400, and any two buttons 400 have the same structure. Each button 400 includes a striking post 420 and a hanging foot 410.

The second sealing portion 520 and the second boss 130 abut against each other, and the third sealing portion 530 and the third boss 140 abut against each other. At least a portion of the second boss 130 is located between the hook portion 412 and the striking post 420, and the third boss 140 is located on the side of the hanging foot 410 opposite to the striking post 420.

[0060] In some embodiments of this application, such as Figure 6 , Figure 7 and Figure 8As shown, the electronic device 10 also includes: a second seal 1000 disposed on the button 400, the second seal 1000 abutting against the frame 100 to block the channel 1100.

[0061] In this embodiment of the application, the structure of the electronic device 10 is further defined, and the electronic device 10 also includes a second sealing member 1000.

[0062] The second seal 1000 is disposed on the button 400. The second seal 1000 cooperates with the frame 100 to disconnect the connection between the opening 110 and the switch 310. That is, the second seal 1000 has the function of blocking the channel 1100 connecting the opening 110 and the switch 310. With the cooperation of the first seal 500 and the second seal 1000, moisture, dirt and other impurities in the external environment will not enter the switch 310 of the flexible circuit board 300 through the opening 110. This ensures the tactile feedback of triggering the button 400, which helps to extend the service life of the flexible circuit board 300 and the button 400, and improves the product's performance and market competitiveness.

[0063] In some embodiments of this application, the second seal 1000 is a sealing ring, which is arranged around the impact post 420.

[0064] In this embodiment of the application, the mating structure of the second seal 1000 and the button 400 is further defined.

[0065] Specifically, a second seal 1000 is provided on the button 400. The second seal 1000 is a sealing ring that surrounds the striking post 420. The sealing ring cooperates with the frame 100 to block the dust entry path that directly reaches the switch 310 through the gap between the opening 110 and the button 400. This prevents moisture, dirt, and other impurities from the external environment from entering the switch 310 of the flexible circuit board 300 through the aforementioned path. This ensures the tactile feedback of the button 400, helps extend the service life of the flexible circuit board 300 and the button 400, and improves the product's performance and market competitiveness.

[0066] In some embodiments of this application, such as Figure 6 As shown, the striking column 420 is provided with an annular groove 422, and the second seal 1000 is arranged around the annular groove 422. The outer peripheral wall of the second seal 1000 is provided with an annular protrusion 1010, and the annular protrusion 1010 abuts against the frame 100.

[0067] In this embodiment, the mating structure of the striking post 420, the second seal 1000, and the frame 100 is further defined.

[0068] Specifically, the striking post 420 is provided with an annular groove 422, and the second seal 1000 is arranged around the annular groove 422. That is, the annular groove 422 serves as the mounting carrier for the second seal 1000, and has the function of installing and fixing the second seal 1000.

[0069] The outer peripheral wall of the second sealing member 1000 is provided with an annular protrusion 1010, which abuts against the frame 100. That is, the annular protrusion 1010 and the frame 100 cooperate to block the dust entry path that directly reaches the switch 310 through the gap between the opening 110 and the button 400.

[0070] Understandably, the annular protrusion 1010 abuts against the frame 100. This ensures the effectiveness and feasibility of blocking the dust entry path of the switch 310 directly through the gap between the opening 110 and the button 400, while reducing the contact area between the second seal 1000 and the frame 100. This reduces the resistance of the frame 100 on the button 400 when the button 400 is triggered, ensuring the tactile feel of the trigger button 400 and preventing the button 400 from getting stuck.

[0071] In some embodiments of this application, there are multiple buttons 400, openings 110, and second seals 1000. Each opening 110 is provided with a button 400, and each button 400 is connected to at least one second seal 1000.

[0072] In this embodiment of the application, the structure of the electronic device 10 is further defined.

[0073] Specifically, there are multiple buttons 400, multiple openings 110, and multiple second seals 1000. That is, there are multiple buttons 400, multiple openings 110, and multiple second seals 1000. Each opening 110 has a button 400, and each button 400 cooperates with at least one second seal 1000. In other words, the electronic device 10 includes multiple buttons 400, which can be used to perform operations such as powering on, locking the screen, and adjusting the volume.

[0074] In some embodiments of this application, such as Figure 7 As shown, the electronic device 10 further includes: a battery cover 600 disposed on the frame 100, and a channel 1100 communicating with the gap 900 between the battery cover 600 and the frame 100; a third seal 700 abutting between the battery cover 600 and the frame 100, and the third seal 700 sealing the gap 900 between the battery cover 600 and the frame 100.

[0075] In this embodiment of the application, the structure of the electronic device 10 is further defined.

[0076] Specifically, the electronic device 10 also includes a battery cover 600 and a third seal 700.

[0077] The battery cover 600 is located on the frame 100, and the gap 900 between the battery cover 600 and the frame 100 is connected to the channel 1100.

[0078] In other words, moisture, dirt and other impurities in the external environment will flow to the switch 310 through the gap 900 and channel 1100 between the battery cover 600 and the frame 100.

[0079] Therefore, this application rationally designs the structure of the electronic device 10, such that the third seal 700 is located between the battery cover 600 and the frame 100, thereby disconnecting the gap 900 between the battery cover 600 and the frame 100 from the switch 310. This prevents moisture, dirt, and other impurities from the external environment from entering the switch 310 of the flexible circuit board 300 through the gap 900 between the battery cover 600 and the frame 100. This helps extend the service life of the flexible circuit board 300, improving product performance and market competitiveness.

[0085] Optionally, without increasing the width occupied by the button 400, this application adds a second seal 1000 (e.g., the second seal 1000 is a flexible member) to the striking post 420 of the button 400, so that the second seal 1000 is pre-pressed against the frame 100 to interrupt the dust ingress path located on the side wall of the button 400.

[0086] Optionally, this application provides a first sealing element 500 (e.g., the first sealing element 500 is a flexible element) between the frame 100 and the bracket 200. Specifically, the first sealing element 500 includes a first sealing portion 510, a second sealing portion 520, and a third sealing portion 530. The frame 100 is provided with a first boss 120, a second boss 130, and a third boss 140. The first sealing portion 510 abuts against the first boss 120, the second sealing portion 520 abuts against the second boss 130, and the third sealing portion 530 abuts against the third boss 140. That is, the first sealing element 500 is used to seal the gap between the frame 100 and the bracket 200, interrupting the dust entry path located at the hanging foot 410 of the button 400. Although dust can enter the entire machine, it cannot reach the switch 310, thereby maintaining a good feel for a long time and extending the product's service life.

[0087] like Figure 2 As shown, two first sealing parts 510, one second sealing part 520 and one third sealing part 530 are attached to the bracket 200. The two first sealing parts 510, one second sealing part 520 and one third sealing part 530 are all used to contact and seal with the frame 100.

[0088] like Figure 3 and Figure 4 As shown, the button 400 has an actuating post 420, and a second seal 1000 (e.g., the second seal 1000 includes a flexible ring) is provided on the side wall of the actuating post 420. The second seal 1000 includes a silicone seal and / or a rubber seal. The button 400 also has a mounting foot 410 for assembling with the bracket 200 to define the button 400.

[0089] like Figure 6 and Figure 7 As shown, the flexible ring located on the striking post 420 interrupts the dust ingress path between the side wall of the button 400 and the frame 100.

[0090] like Figure 7 As shown, the battery cover 600 is bonded to the frame 100 via a third seal 700 (e.g., the third seal 700 includes sealant). The sealant and the frame 100 have a certain overlap width, blocking the dust entry path from the gap 900 between the battery cover 600 and the frame 100 to the switch 310 of the flexible circuit board 300.

[0091] like Figure 8 As shown, the button 400 on the left is a volume button. The volume button's mounting feet 410 are held in place by the bracket 200, preventing the volume button from coming out. The frame 100 has two first protrusions 120, and the volume button's mounting feet 410 are located between the two first protrusions 120.

[0092] like Figure 9and Figure 10 As shown, the first boss 120, the second boss 130, and the third boss 140 on the frame 100 and the first sealing part 510, the second sealing part 520, and the third sealing part 530 on the bracket 200 are in contact with each other, sealing and isolating the dust that enters from the hanging foot 410 of the button 400.

[0093] Optionally, such as Figure 8 As shown, the pre-compression seal is applied in the thickness direction of the entire machine, without occupying space in the width direction of the entire machine.

[0094] Optionally, instead of using the flexible first seal 500 for pre-pressurization, the bracket 200 can integrally injection mold the first seal 500 onto the bracket 200, and make the first seal 500 contact the first boss 120, the second boss 130, and the third boss 140 of the frame 100 to achieve a seal. That is, the first seal 500 provided on the bracket 200 can be either a flexible or a rigid component.

[0095] Optionally, such as Figure 7 As shown, the electronic device 10 also includes a display screen 800, which is disposed opposite to the battery cover 600.

[0096] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0097] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
