[0041] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0042] Please see Figure 1 , Figure 2 and Figure 6 As shown, this application embodiment provides an operating device 100 with a button structure that is easy to disassemble and replace. It includes a main housing 1, a first circuit board 5, a button structure 7, and a faceplate 3. A first opening 111 is recessed along a first direction X on one side surface of the main housing 1. The first circuit board 5 is disposed in the first opening 111. The button structure 7 is disposed in the first opening 111 and is located on the side of the first circuit board 5 facing away from the first opening 111. The button structure 7 is used to form contact with the surface of the first circuit board 5 when pressed along the first direction X. The faceplate 3 is detachably installed on the main housing 1. In the first direction X, the faceplate 3 is aligned with a part of the button structure 7 and is located on the side of the button structure 7 away from the first circuit board 5.

[0043] Therefore, when the faceplate 3 is assembled on the main housing 1, the faceplate 3 can restrict the button structure 7 from being removed from the first opening 111. When the button structure 7 needs to be replaced, the faceplate 3 can be removed from the main housing 1 to expose the button structure 7 and allow the button structure 7 to be taken out from the first opening 111, thus realizing the detachable replacement of the button structure 7.

[0044] The first direction X can be the thickness direction of the main housing 1, or the pressing direction of the button structure 7.

[0045] Please see Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the operating device 100 with a button structure that is easy to disassemble and replace may further include a display screen 81. The display screen 81 is disposed on one side surface of the main housing 1, specifically on the same side surface of the main housing 1 as the button structure 7, with the button structure 7 located beside the display screen 81. Figure 2 As shown, the faceplate 3 is frame-shaped, with a second opening 30 forming in the middle that extends through the first direction X. The second opening 30 is used to expose at least the display area of ​​the display screen 81 so that the operator can obtain relevant information from the display screen 81.

[0046] The operating device 100 with a button structure that is easy to disassemble and replace may also include a second circuit board (not shown), which is connected to the first circuit board 5 and the display screen 81. The second circuit board receives button control information from the first circuit board 5 and outputs corresponding display information on the display screen 81 according to the button control information.

[0047] In one embodiment, the second circuit board can serve as the main control circuit board and be used to connect to external devices or signal sources. For example, the external device can be a detection device for measuring certain signals. Specifically, the operating device 100 with a button structure that is easy to disassemble and replace is used on a navigation device, and the second circuit board is used to connect to the detection device on the navigation device to display and process relevant detection information on the display screen 81.

[0048] Optionally, in the first direction X, at least a portion of the bezel area of ​​the display screen 81 is covered by the faceplate 3. In this way, the faceplate 3 not only provides fixation and positioning for the display screen 81, but also seals the bezel area of ​​the display screen 81 to prevent moisture and other substances from entering through the space between the faceplate 3 and the bezel area.

[0049] like Figure 2 As shown, the main housing 1 has a mounting surface 113, which corresponds to the back of the display screen 81. The display screen 81 is mounted on the mounting surface 113. Furthermore, the display screen 81 can be connected to the main housing 1 by providing an adhesive layer (not shown) between the mounting surface 113 and the back of the display screen 81.

[0050] like Figure 3 , Figure 5 and Figure 7 As shown, in one embodiment, the main housing 1 is provided with a receiving cavity 10, and the second circuit board is disposed within the receiving cavity 10. The receiving cavity 10 is a sealed space that ensures that the second circuit board is not corroded by moisture.

[0051] For more details, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, the main housing 1 includes a first housing 11 and a second housing 12 connected to each other. At least one of the first housing 11 and the second housing 12 is concave, so that when the first housing 11 and the second housing 12 are mated, the aforementioned accommodating cavity 10 is formed. A first opening 111 is provided on the surface of the first housing 11 facing away from the second housing 12.

[0052] The first housing 11 and the second housing 12 can optionally be mated in the first direction X. This results in minimal recesses in the first housing 11 and the second housing 12, facilitating manufacturing. For example... Figure 2 As shown, the first housing 11 has a third opening 112 communicating with the accommodating cavity 10, and the aforementioned mounting surface 113 is arranged around the third opening 112. The third opening 112 is used for the connection between the first circuit board 5 and the display screen 81. The adhesive layer disposed between the mounting surface 113 and the back of the display screen 81 can simultaneously have a sealing structure to seal both the third opening 112 and the accommodating cavity 10.

[0053] The first housing 11 and the second housing 12 are detachably connected. For example, the first housing 11 and the second housing 12 are connected by fasteners such as screws and bolts.

[0054] like Figure 2 , Figure 3 As shown, in one embodiment, the operating device 100 with a button structure that is easy to disassemble and replace may further include a connector 82. The second housing 12 is provided with a fourth opening 121 that communicates with the accommodating cavity 10. The connector 82 passes through the fourth opening 121, with one end located inside the accommodating cavity 10 and connected to the second circuit board, and the other end located outside the main housing 1 for connection with the aforementioned detection device.

[0055] Further, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the operating device 100 with a button structure that allows for easy disassembly and replacement also includes a connector 83. The connector 83 is located at the edge of the main housing 1 and is connected to at least one of the first housing 11 and the second housing 12. The connector 83 is used to fix the main housing 1 in the desired installation position, for example, to install the operating device 100 with a button structure that allows for easy disassembly and replacement onto the bridge of a ship.

[0056] The connector 83 can be a bolt, screw or other fastener, or other types of fasteners.

[0057] like Figure 2As shown, in one embodiment, the first housing 11 and the second housing 12 are provided with connecting holes 14 communicating along the first direction X. Each connector 83 is located in the two aligned connecting holes 14, so that the connector 83 passes through the first housing 11 and the second housing 12. Based on the first housing 11 and the second housing 12 being fixedly connected by fasteners, the connector 83 further fixes the first housing 11 and the second housing 12 to ensure that the main housing 1 can be stably installed as a whole.

[0058] Please see Figure 1 , Figure 3 As shown, in the first direction X, the faceplate 3 covers each connector 83. The purpose of this arrangement is to hide the connectors 83, making the overall surface of the operating device 100, which has a structure for easy disassembly and replacement of buttons, more aesthetically pleasing.

[0059] To establish the connection between the first circuit board 5 and the second circuit board, please refer to... Figure 9 As shown, in one embodiment, the second housing 12 is further provided with a wiring hole 115 connecting the first opening 111 and the accommodating cavity 10. The first circuit board 5 passes through the wiring hole 115 and is connected to the second circuit board. The wiring hole 115 may be filled with a sealing structure such as sealant to isolate the second opening 30 from the accommodating cavity 10, further ensuring that the second circuit board is not affected by moisture.

[0060] The wiring hole 115 can be opened along the first direction X, or along an inclined or even perpendicular direction X, as long as it facilitates the connection between the first circuit board 5 and the second circuit board.

[0061] Optionally, please refer to Figure 9 As shown, the wiring hole 115 is opened through the inner bottom surface of the first opening 111 along the first direction X. The purpose of this arrangement is that the wiring hole 115 is blocked and covered by the first circuit board 5 in the first direction X, so the first circuit board 5 can form a certain degree of closure of the wiring hole 115.

[0062] Alternatively, the side surface of the first circuit board 5 facing the first opening 111 can be fixed to the inner bottom surface of the first opening 111 by an adhesive layer or the like, which can further increase the sealing effect of the first circuit board 5 on the wiring hole 115.

[0063] In one alternative embodiment, the first circuit board 5 is a flexible circuit board. This arrangement facilitates the installation of the first circuit board 5 within the first opening 111 and the connection between the first circuit board 5 and the second circuit board. Furthermore, the location of the wiring hole 115 can be more flexible, and can be designed with consideration for the ease of manufacturing the second housing 12.

[0064] like Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9 As shown, in one embodiment, the main housing 1 further includes a sealing ring 13 disposed between the first housing 11 and the second housing 12 and surrounding the accommodating cavity 10. The sealing ring 13 achieves the airtightness of the accommodating cavity 10.

[0065] Specifically, please refer to Figure 4 , Figure 6 and Figure 8 As shown, one of the sides of the first housing 11 facing the second housing 12 and the side of the second housing 12 facing the first housing 11 is provided with a sealing protrusion 114 in a closed ring shape surrounding the accommodating cavity 10, and the other is provided with a sealing groove 120. The sealing ring 13 is at least partially located in the sealing groove 120 and abuts against the sealing protrusion 114. The sealing groove 120 can limit the sealing ring 13 and restrict the deformation direction of the sealing ring 13 so that the sealing ring 13 is compressed as much as possible in the first direction X.

[0066] like Figure 2 , Figure 3 and Figure 4 As shown, the edge of the face shell 3 is provided with a plurality of buckles 31 protruding toward the second opening 30 of the face shell 3. The buckles 31 are used to abut against the surface edge of the main shell 1 on the side away from the button structure 7, that is, the surface edge of the second shell 12 on the side away from the first shell 11.

[0067] In practical applications, the buckle 31 has a small thickness and length, so the buckle 31, and even a part of the faceplate 3 connected to the opening, can deform to allow the buckle 31 to abut against the side of the main housing 1 away from the button structure 7, and to detach from the side of the main housing 1 away from the button structure 7. This achieves easy disassembly and assembly between the faceplate 3 and the main housing 1.

[0068] Optionally, such as Figure 4 As shown, a recessed slot 122 can be provided at the edge of the surface of the second housing 12 facing away from the first housing 11, and the buckle 31 is located in the slot 122. The purpose of this arrangement is to ensure that the buckle 31 is flush with the other surfaces of the second housing 12, so that the surface of the operating device 100 with the button structure that is easy to disassemble and replace can be flush with the surface facing away from the button structure 7.

[0069] In other alternative embodiments, the faceplate 3 and the main housing 1 can also be connected by other convenient detachable methods.

[0070] Please see Figure 2 and Figure 8As shown, the first circuit board 5 includes a circuit board body 51 and one or more pressure sensors 52 disposed on the circuit board body 51. The button structure 7 includes a pressing part 71 corresponding to the number of pressure sensors 52. When the pressure sensor 52 is subjected to pressure from the pressing part 71, its central protrusion will collapse downward, thereby turning on the circuit corresponding to the circuit board body 51. The first circuit board 5 will then receive the button control signal and perform the corresponding operation.

[0071] like Figure 2 As shown, there are multiple pressing parts 71 and multiple pressing sensors 52.

[0072] Optionally, such as Figure 2 As shown, the first circuit board 5 also includes at least one indicator light 53 disposed on the circuit board body 51. The indicator light 53 is used to indicate the triggering status of the corresponding press sensor 52.

[0073] like Figure 2 As shown, indicator lights 53 are arranged corresponding to each press sensor 52 to indicate the triggering status of a press sensor 52.

[0074] Please continue reading. Figure 2 and Figure 7 As shown, the first circuit board 5 also includes a protective layer 54 disposed on the first circuit board 5 and covering the pressure sensor 52 and the indicator light 53. The protective layer 54 may be a flexible and light-transmitting component. The purpose of this arrangement is that the protective layer 54 is light-transmitting, thus allowing the light from the indicator light 53 to pass through the protective layer 54 and illuminate at least a portion of the area around each pressing part 71. The protective layer 54 is a flexible component, which can be pressed between the face shell 3 and the first housing 11 of the main housing 1, thereby sealing the circuit board body and its pressure sensor 52 and indicator light 53, and preventing moisture and other substances from corroding the first circuit board 5.

[0075] Specifically, such as Figure 2 , Figure 6 and Figure 7 As shown, the protective layer 54 forms a clearance portion 540 facing the button structure 7 corresponding to each indicator light 53, and the indicator lights 53 are respectively located within the clearance portion 540. Based on this, the side surface of each pressing part 71 facing the first circuit board 5 can be adaptively set to ensure that the indicator light 53 is not pressed while the pressing sensor 52 is pressed towards the first circuit board 5.

[0076] In the button structure 7, the multiple pressing parts 71 can be an integrated structure, such as an integrated flexible structure, so that when the operator presses one of the pressing parts 71, only the corresponding pressing sensor 52 is triggered, and the adjacent pressing sensor 52 is not triggered. Furthermore, the integrated pressing part 71 is easier to manufacture and assemble.

[0077] In other alternative embodiments, the plurality of pressing portions 71 can be independent structures, such as independent flexible structures or independent rigid structures. It is understood that, in this case, in the first direction X, the faceplate 3 should be aligned with a portion of each pressing portion 71 to prevent each pressing portion 71 from disengaging from the first opening 111.

[0078] This application uses a structure in which multiple pressing parts 71 are integrated as an example for illustration.

[0079] like Figure 2 , Figure 7 and Figure 8 As shown, a limiting structure 1110 is recessed on the inner sidewall of the first opening 111, and a mating structure 70 adapted to the limiting structure 1110 is provided on the edge of the button structure 7. The mating of the limiting structure 1110 and the mating structure 70 can limit the button structure 7 in a plane perpendicular to the first direction X, making it easy for the button structure 7 to maintain a corresponding relationship with the first circuit board 5.

[0080] One of the limiting structure 1110 and the mating structure 70 is a limiting groove, and the other is a limiting protrusion.

[0081] Understandably, in the first direction X, the limiting groove extends at least to the surface of the main housing 1 or penetrates to the surface of the button structure 7 opposite to the first circuit board 5, so that the button structure 7 can be removed in the first direction X.

[0082] In the first direction X, the shell 3 at least covers the limiting structure 1110 and the mating structure 70.

[0083] Taking the limit protrusion set on the button structure 7 as an example, please refer to Figure 2 As shown, in one embodiment, one or more pressing portions 71 have limiting protrusions on their edges.

[0084] Furthermore, please refer to the following: Figure 2 , Figure 6 and Figure 8 As shown, the button structure 7 also includes a support portion 72, which is located on the side of each pressing portion 71 facing the first circuit board 5. The support portion 72 is a rigid component and has multiple through holes 720. The through holes 720 avoid the pressure sensor 52 and the indicator light 53, so that each pressing portion 71 can contact the corresponding pressure sensor 52. The first support portion 72 can support the area of ​​the pressing portion 71 other than the pressure sensor 52 and the indicator light 53, preventing the operator from applying pressure to other areas of the first circuit board 5 when pressing the pressing portion 71.

[0085] The mating structure 70 can be simultaneously provided on the support part 72 and the pressing part 71, such as Figure 2 . Figure 7 and Figure 8 As shown. It is understood that the mating structure 70 on the support 72 and the upper mating structure 70 on the pressing part 71 do not need to correspond one-to-one. They can each be adapted to at least a portion of the limiting structure 1110 on the first housing 11.

[0086] In other alternative embodiments, the mating structure 70 may be provided separately on the pressing part 71 or separately on the supporting part 72.

[0087] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
