DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In the present invention, unless otherwise expressly specified and limited, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0020] As attached Figure 1-4 As shown, a modular design of a display includes a shell of the display, the shell includes a front panel 1, and at least one functional area 4 is provided on the front panel 1. The functional area 4 is detachably connected to the front panel 1, and the functional area 4 is installed into or removed from the front panel 1 through the front panel 1.

[0021] As a specific solution, a groove 11 is formed inwardly at a position corresponding to the functional area 4 on the front panel 1, the depth of the groove 11 is preferably 1~5 mm, the bottom of the groove 11 is preferably flat, a through hole 12 is arranged in the groove 11, and a limiting step 13 is extended inwardly from the inner wall of the through hole 12, and at least one fixing ear 121 is extended inwardly 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 falling into the shell, the mounting plate 41 and the fixing ear 121 are fixedly connected by a fixing member, and the fixing member is preferably a bolt, and the rear part of the mounting plate 41 is fixedly connected to the functional area circuit board 42, and a main circuit board 5 is fixed in the shell, and the main circuit board 5 is electrically connected to the functional area circuit board 42.

[0022] The mounting plate 41 and the functional area circuit board 42 can be hingedly fixed or welded. Preferably, a bracket is set on the mounting plate 41 and the bracket and the circuit board 42 are fixed with bolts. It is an existing technology to realize the button function and indicator light function on a single board through the circuit board. This application does not involve the improvement of this technology, but rather separates the circuit board and the mounting plate for modular design.

[0023] The main circuit board 5 is provided with a first electrical connection socket 51 , and the functional area circuit board 42 is provided with a second electrical connection socket 421 . The first electrical connection socket 51 and the second electrical connection socket 421 are connected via a line.

[0024] It should be noted that the electrical connection between circuit boards through sockets and circuits is a mature existing technology. This application does not involve any improvement in principle to these components, which will not be repeated here. The only point to note is that in order to ensure smooth installation, it is necessary to ensure that the connection line is long enough and the position of the first electrical connection socket 51 does not interfere with the installed circuits and plugs. During installation, first pass the line through the through hole 12 so that the first electrical connection socket 51 and the second electrical connection socket 421 are connected through the line to form an electrical connection. After testing, install and fix the mounting plate 41.

[0025] Further, such as Figure 1-2 As shown, when the mounting plate 41 is fixed in the through hole 12, the front end surface of the mounting plate 41 is flush with the bottom of the groove 11, and a protective film 17 covering the bottom of the groove 11 is glued and fixed in the groove 11. In detail, the contact surface between the protective film 17 and the groove 11 is covered with colloid to form waterproof protection, and the outer surface of the protective film 17 is printed with a pattern to serve as the user's contact area.

[0026] Further, such as Figure 2-3 As shown, the inner side wall of the through hole 12 is provided with a disassembly groove 122 outwardly, and the side wall of the mounting plate 41 is exposed at the disassembly groove 122, so that when disassembling the mounting plate 41, hands or tools can enter to pull out the mounting plate 41.

[0027] Further explanation of the accompanying drawings: 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 a mounting plate 41, which is a whiteboard without other functions. The structure of the bottom functional area 4 corresponds to Figure 4 The above structure is only to provide more implementation options and is not intended to limit the present invention.

[0028] 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, and a sound-emitting device 15 is fixed in the shell behind the sound hole 14. The sound-emitting device 15 can be a speaker, a speaker or other sound-emitting device. A diversion cavity 6 is provided between the sound-emitting device 15 and the sound hole 14. The diversion cavity 6 is provided with a second sound hole 621 facing the sound-emitting device 15. A diversion structure and a water outlet 61 are also provided in the diversion cavity 6. The diversion structure is used to block the liquid entering through the sound hole 14 from entering the second sound hole 621, and to divert the liquid to the water outlet 61.

[0029] Furthermore, the guide cavity 6 includes a shell fixedly connected to the rear side of the front panel 1, and a baffle 62 is fixedly connected to the guide cavity 6. The baffle 62 is as shown in FIG. Figure 8As shown, a second sound hole 621 is provided on the baffle 62, and a guide plate 622 is provided in front of the second sound hole 621, and the bottom of the guide plate 622 is lower than the bottom of the second sound hole 621; the top of the guide plate 622 is higher than the top of the second sound 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 hole 621, which on the one hand blocks more water from entering, and on the other hand ensures that the sound channel is not blocked.

[0030] Furthermore, the water outlet 61 is arranged at the bottom of the diversion cavity 6, and a diversion block 63 is arranged in the diversion cavity 6 on the side of the water outlet 61. The height of the diversion block 63 changes from high to low from far away from the water outlet 61 to close to the water outlet 61, so that the water entering the sound hole 14 converges to the water outlet 61.

[0031] Furthermore, the bottom plate of the diversion cavity 6 can be directly located at the bottom of the display housing, and the water directly leaves from the water outlet 61, or Figure 5-7 As shown, the guide cavity 6 is wrapped in the entire housing. At this time, for the installation frame 3 on the side of the housing, at least one drainage hole needs to be provided at the corresponding position at the bottom.

[0032] Furthermore, the sound-generating end of the sound-generating device 15 is fixedly connected to the rear end of the diversion cavity 6, and a waterproof breathable membrane 64 is glued and fixed between the sound-generating end of the sound-generating device 15 and the diversion cavity 6. The diversion structure can block most of the water ingress, but the possibility of further water ingress is not ruled out. Therefore, the waterproof breathable membrane 64 is designed for safety, and a waterproof rubber strip can be further arranged between the sound-generating device 15 and the diversion cavity 6 to prevent water from further entering the shell.

[0033] A heat conduction structure in the core area of ​​a display circuit board, such as Figure 9-13 As shown, the shell includes a display, the shell includes a rear cover 2, a heat sink 21 is provided on the rear cover 2, a main circuit board 5 is fixed in the shell, a core circuit board 52 is fixed on the main circuit board 5, a core component 521 is provided on the core circuit board 52, a heat dissipation bracket 7 is provided at the rear of the core circuit board 52, a first soft thermal conductive sheet 71 is provided on one side of the heat dissipation bracket 7, and the first soft thermal conductive sheet 71 abuts the core component 521; a second soft thermal conductive sheet 72 is provided on the other side of the heat dissipation bracket 7, and the second soft thermal conductive sheet 72 abuts the rear cover 2.

[0034] The core component 521 generally refers to a chip, especially a chip that generates the highest heat when in operation in the entire device.

[0035] Thus, a long heat conduction channel can be formed through the heat dissipation bracket 7. The heat dissipation bracket 7 itself serves as a hard structure to extend the channel, and the first soft heat conductive sheet 71 and the second soft heat conductive sheet 72 ensure the reliability of contact.

[0036] Furthermore, the main circuit board 5 is fixedly connected to the plug-in support 522, and the core circuit board 52 is fixed on the plug-in support 522. The plug-in support 522 itself is a prior art. The plug-in connection between the core circuit board 52 and the plug-in support 522 realizes fixation on the one hand and electrical connection on the other hand. This application does not involve improvements to the plug-in support 522 structure itself. This structure is adopted to raise the core circuit board 52 and move it closer to the rear cover 2; the heat dissipation bracket 7 includes a bracket body, and at least three legs 73 are provided on the peripheral side of the bracket body. The legs 73 are fixedly connected to the main circuit board 5, and the legs 73 abut the core circuit board 52 laterally, and are preferably arranged around the core circuit board 52, so that multiple legs 73 form a plug-in relationship with the core circuit board 52, and the legs 73 extend out of the fixed step 731 toward the direction of the core circuit board 52. The core circuit board 52 and the fixed step 731 are fixedly connected by a fixing member. Through this structure, on the one hand, a fool-proof design is formed to facilitate installation and positioning by the installer, and on the other hand, a reliable fixed relationship of the main circuit board 5-core circuit board 52-heat dissipation bracket 7 is formed.

[0037] Furthermore, the heat dissipation bracket 7 is provided with an extension block 74 toward the core element 521, and the extension block 74 is fixedly connected to the first soft heat conductive sheet 71. Through the extension block 74, the heat dissipation bracket 7 itself does not need to be made very thick, but the extension block 74 is used as part of the heat dissipation channel.

[0038] Furthermore, the area of ​​the first soft thermally conductive sheet 71 is larger than the area of ​​the core element 521, and the distance between the extension block 74 and the core element 521 is smaller than the thickness of the first soft thermally conductive sheet 71, ensuring that the first soft thermally conductive sheet 71 covers and contacts the core element 521. The area of ​​the second soft thermally conductive sheet 72 is larger than the area of ​​the bracket body of the heat dissipation bracket 7, and the distance between the heat dissipation bracket 7 and the back cover 2 is smaller than the thickness of the second soft thermally conductive sheet 72, which increases the heat transfer effect on the one hand and ensures contact reliability on the other.

[0039] Furthermore, the first soft thermally conductive sheet 71 and the second soft thermally conductive sheet 72 are both thermally conductive silicone sheets, which are conventional in technology.

[0040] Further, such as Figure 14 As shown, the rear part of the front panel 1 is fixedly connected to the rear cover plate 2, and the two are connected by bolts through four fixing columns at at least four corners. A frame-shaped first rubber strip 31 is provided on the periphery of the front panel 1, and the first rubber strip 31 can be buried in the groove as a whole. A frame-shaped second rubber strip 32 is provided on the rear cover plate 2, and also includes a mounting frame 3. The front end of the mounting frame 3 abuts the first rubber strip 31, and the rear end of the mounting frame 3 extends inwardly to the inner eaves, and the inner eaves abuts the second rubber strip 32. The inner eaves is fixedly connected to the rear cover plate 2. The first rubber strip 31 and the second rubber strip 32 are preferably conductive rubber strips, which can prevent water ingress on the one hand and achieve an overall electromagnetic shielding effect on the other hand.

[0041] Further, such as Figure 15-17 As shown, an external screen mounting groove 16 is provided on the rear side of the front panel 1, and an external screen 8 is provided in the external screen mounting groove 16. A positioning block 161 extends inward from the external screen mounting groove 16 to abut against the external screen 8. At least one positioning frame 81 is provided on the rear part of the front panel 1, and the front part of the positioning frame 81 abuts against the external screen 8. A frame-shaped third rubber strip is provided between the external screen 8 and the external screen mounting groove 16 for waterproofing, and the third rubber strip is not drawn in the figure. Through this design, the external screen 8 is replaceable. The external screen 8 is not a display screen, and can be a touch screen, an electroplated screen, or an ordinary glass plate according to user needs.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
