[0037] 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.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] As attached Figure 1-4 As shown, a modular design for a display includes a housing of the display, the housing including a front panel 1, the front panel 1 having at least one functional area 4, the functional area 4 being detachably connected to the front panel 1, the functional area 4 being inserted into or removed from the front panel 1 through the front panel 1.

[0040] As a specific solution, a groove 11 is formed inward on the front panel 1 corresponding to the position of the functional area 4. The depth of the groove 11 is preferably 1~5mm, and the bottom of the groove 11 is preferably flat. A through hole 12 is provided in the groove 11, and a limiting step 13 extends inward from the inner wall of the through hole 12. At least one fixing ear 121 extends inward from the inner wall of the limiting step 13. The functional area 4 includes a mounting plate 41. The shape of the mounting plate 41 matches the through hole 12, and the mounting plate 41 abuts against the front end of the limiting step 13 and is blocked by the limiting step 13 to prevent it from falling into the housing. The mounting plate 41 and the fixing ear 121 are fixedly connected by a fastener, preferably a bolt. The rear part of the mounting plate 41 is fixedly connected to the functional area circuit board 42. A main circuit board 5 is fixed inside the housing, and the main circuit board 5 is electrically connected to the functional area circuit board 42.

[0041] The mounting plate 41 and the functional area circuit board 42 can be fixed by hinge or welding. Preferably, a bracket is set on the mounting plate 41 and the bracket is bolted to the circuit board 42. Implementing button functions and indicator light functions on a single board through a circuit board is existing technology. This application does not involve improving this technology, but rather separates the circuit board and mounting plate for modular design.

[0042] The main circuit board 5 is provided with a first electrical connection port 51, and the functional area circuit board 42 is provided with a second electrical connection port 421. The first electrical connection port 51 and the second electrical connection port 421 are connected by a line.

[0043] It should be noted that the electrical connection between circuit boards via connectors and circuits is a mature existing technology. This application does not involve any fundamental improvement to these components, so it will not be elaborated here. Only the points that need attention are mentioned: to ensure smooth installation, the connection line needs to be long enough, and the position of the first electrical connection connector 51 should not interfere with the inserted line or plug. During installation, first pass the line through the through hole 12 so that the first electrical connection connector 51 and the second electrical connection connector 421 are connected by the line to form an electrical connection. After testing and confirming that there are no errors, install and fix the mounting plate 41.

[0044] Furthermore, such as Figure 1-2 As shown, when the mounting plate 41 is fixed in the through hole 12, the front end face of the mounting plate 41 is flush with the bottom of the groove 11. A protective film 17 covering the bottom of the groove 11 is glued and fixed in the groove 11. Specifically, the contact surface between the protective film 17 and the groove 11 is covered with adhesive to form a waterproof protection. The outer surface of the protective film 17 is printed with a pattern to serve as the contact area for the user.

[0045] Furthermore, such as Figure 2-3 As shown, the inner sidewall of the through hole 12 is provided with a disassembly groove 122 facing outward. The sidewall of the mounting plate 41 is exposed at the disassembly groove 122, which is used to pry out the mounting plate 41 by hand or tool when disassembling the mounting plate 41.

[0046] Further explanation of the accompanying drawings: Based on Figure 1 The left functional area 4 includes a mounting plate 41 and a functional area circuit board 42; the right functional area 4 only includes the mounting plate 41 and is a blank board without other functions. The structure of the bottom functional area 4 is corresponding. Figure 4 The above structure is only intended to provide more implementation options and is not intended to limit the present invention.

[0047] A waterproof structure for the speaker area of ​​a display, such as Figure 5-8 As shown, a sound hole 14 is provided on the front panel 1. A sound-generating device 15 is fixed in the housing behind the sound hole 14. The sound-generating device 15 can be a loudspeaker, a speaker, or other sound-generating device. A flow guiding cavity 6 is provided between the sound-generating device 15 and the sound hole 14. A second sound hole 621 is provided in the flow guiding cavity 6 facing the sound-generating device 15. A flow guiding structure and a water outlet 61 are also provided in the flow guiding cavity 6. The flow guiding structure is used to block the liquid entering through the sound hole 14 from entering the second sound hole 621 and to guide the liquid to the water outlet 61.

[0048] Furthermore, the flow guiding cavity 6 includes a housing fixedly connected to the rear side of the front panel 1, and a baffle 62 is fixedly connected inside the flow guiding cavity 6, the baffle 62 being as follows: Figure 8As shown, a second sound passage hole 621 is provided on the baffle 62, and a guide plate 622 is provided in front of the second sound passage hole 621. The bottom of the guide plate 622 is lower than the bottom of the second sound passage hole 621; the top of the guide plate 622 is higher than the top of the second sound passage hole 621 and is fixedly connected to the baffle 62, so that the guide plate 622 forms an umbrella-shaped structure for the second sound passage hole 621, which blocks more water from entering on the one hand, and ensures that the sound transmission channel is not blocked on the other hand.

[0049] Furthermore, the water outlet 61 is located at the bottom of the flow guiding cavity 6, and a flow guiding block 63 is provided in the flow guiding cavity 6 on the side of the water outlet 61. The height of the flow guiding block 63 changes from high to low as it moves away from the water outlet 61 to close to the water outlet 61, so that the water entering the sound hole 14 converges towards the water outlet 61.

[0050] Furthermore, the base plate of the flow channel 6 can be located directly at the bottom of the display housing, allowing water to exit directly from the water outlet 61, or as... Figure 5-7 As shown, the flow guide cavity 6 is enclosed within the housing. At this time, for the mounting frame 3 on the side of the housing, at least one drainage hole needs to be provided at the corresponding position at the bottom.

[0051] Furthermore, the sound-generating end of the sound-generating device 15 is fixedly connected to the rear end of the flow-guiding cavity 6. A waterproof and breathable membrane 64 is glued and fixed between the sound-generating end of the sound-generating device 15 and the flow-guiding cavity 6. The flow-guiding structure can block most of the water ingress, but the possibility of further water ingress cannot be ruled out. Therefore, the waterproof and breathable membrane 64 is designed for safety. A waterproof strip can be further set between the sound-generating device 15 and the flow-guiding cavity 6 to prevent water from further entering the housing.

[0052] A heat-conducting structure for the core area of ​​a display circuit board, such as Figure 9-13 As shown, the display includes a housing, which includes a rear cover plate 2. A heat sink 21 is disposed on the rear cover plate 2. A main circuit board 5 is fixed inside the housing. A core circuit board 52 is fixed on the main circuit board 5. A core component 521 is disposed on the core circuit board 52. A heat dissipation bracket 7 is disposed at the rear of the core circuit board 52. A first flexible heat-conducting sheet 71 is disposed on one side of the heat dissipation bracket 7, which abuts against the core component 521. A second flexible heat-conducting sheet 72 is disposed on the other side of the heat dissipation bracket 7, which abuts against the rear cover plate 2.

[0053] The core component 521 generally refers to the chip, especially the chip that generates the most heat during operation in the whole machine.

[0054] This allows a long heat conduction channel to be formed through the heat dissipation bracket 7. The heat dissipation bracket 7 itself is a rigid structure that extends the channel, and the first soft heat conduction sheet 71 and the second soft heat conduction sheet 72 ensure reliable contact.

[0055] Furthermore, a plug-in support 522 is fixedly connected to the main circuit board 5, and the core circuit board 52 is fixed to the plug-in support 522. The plug-in support 522 itself is existing technology. The plug-in connection between the core circuit board 52 and the plug-in support 522 achieves both fixation and electrical connection. This application does not involve any improvement to the structure of the plug-in support 522 itself. This structure is used to support the core circuit board 52 and bring it closer to the rear cover plate 2. The heat dissipation bracket 7 includes a bracket body, and at least three legs 73 are arranged around the periphery of the bracket body. The legs 73 are fixedly connected to the main circuit board 5, and the legs 73 abut against the core circuit board 52 on their sides. Preferably, they are arranged around the core circuit board 52, so that multiple legs 73 form a plug-in relationship with the core circuit board 52. The legs 73 extend a fixed step 731 towards the core circuit board 52. The core circuit board 52 and the fixed step 731 are fixedly connected by a fastener. This structure forms a foolproof design, which is convenient for the installer to position the device. It also forms a reliable fixed relationship between the main circuit board 5, the core circuit board 52, and the heat dissipation bracket 7.

[0056] Furthermore, the heat dissipation bracket 7 is provided with an extension block 74 facing the core component 521. The extension block 74 is fixedly connected to the first soft heat-conducting sheet 71. Through the extension block 74, the heat dissipation bracket 7 itself does not need to be very thick, but the extension block 74 is used as part of the heat dissipation channel.

[0057] Furthermore, the area of ​​the first flexible heat-conducting sheet 71 is larger than the area of ​​the core component 521, and the distance between the elongated block 74 and the core component 521 is smaller than the thickness of the first flexible heat-conducting sheet 71, ensuring that the first flexible heat-conducting sheet 71 covers and contacts the core component 521. The area of ​​the second flexible heat-conducting sheet 72 is larger than the area of ​​the support body of the heat dissipation bracket 7, and the distance between the heat dissipation bracket 7 and the rear cover plate 2 is smaller than the thickness of the second flexible heat-conducting sheet 72, which increases the heat transfer effect on the one hand and ensures the reliability of contact on the other.

[0058] Furthermore, both the first soft thermal conductive sheet 71 and the second soft thermal conductive sheet 72 are thermally conductive silicone sheets, which are existing technologies.

[0059] Furthermore, such as Figure 14 As shown, the rear cover plate 2 is fixedly connected to the rear of the front panel 1, and the two are connected by bolts through four fixing posts at at least four corners. The front panel 1 is provided with a frame-shaped first adhesive strip 31 around its periphery. The first adhesive strip 31 can be completely embedded in the groove. The rear cover plate 2 is provided with a frame-shaped second adhesive strip 32. It also includes a mounting frame 3. The front end of the mounting frame 3 abuts against the first adhesive strip 31, and the rear end of the mounting frame 3 extends inward to the inner edge. The inner edge abuts against the second adhesive strip 32. The inner edge is fixedly connected to the rear cover plate 2. The first adhesive strip 31 and the second adhesive strip 32 are preferably conductive rubber strips, which prevent water ingress and achieve an overall electromagnetic shielding effect.

[0060] Furthermore, such as Figure 15-17 As shown, an outer screen mounting groove 16 is provided on the rear side of the front panel 1, and an outer screen 8 is provided in the outer screen mounting groove 16. A positioning block 161 extends inward from the outer screen mounting groove 16 and abuts against the outer screen 8. At least one positioning bracket 81 is provided at the rear of the front panel 1, and the front of the positioning bracket 81 abuts against the outer screen 8. A frame-shaped third adhesive strip is provided between the outer screen 8 and the outer screen mounting groove 16 for waterproofing. The third adhesive strip is not shown in the figure. Through this design, the outer screen 8 can be replaced. The outer screen 8 is not a display screen. It can be a touch screen, an electroplated screen, or an ordinary glass plate according to the user's needs.

[0061] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
