Description

Technical Field

[0001] This invention relates to the field of central control screens, and in particular to a heat-dissipating shipborne central control screen. Background Technology

[0002] In today's rapidly developing technological world, physical buttons on ships are gradually being replaced by central control screens. Many ship manufacturers have unanimously adopted central control screen designs, partly to keep up with technological trends and partly to enhance the ship's technological feel, leading to the widespread adoption of central control screens.

[0003] Existing central control screens are mostly manufactured by traditional industries, which do not have high requirements for heat dissipation and waterproofing. However, heat-dissipating shipboard central control screens are also installed on the deck, which means they are exposed to rain or water vapor corrosion. Therefore, they require strict waterproof sealing. When the sealing becomes strict, heat dissipation becomes difficult. Existing central control screens are not suitable for the development of the shipbuilding industry. There is a need for a heat-dissipating shipboard central control screen that can be manufactured for the shipbuilding industry and is both waterproof and has good heat dissipation. Summary of the Invention

The diameter of the second through hole is smaller than that of the first boss. The main frame, the sealing ring, and the rear cover frame are connected and fixed by screws passing through the second through hole, the first through hole, and the fastening holes on the first bosses.

[0010] Preferably, a heat-conducting copper sheet is also provided at the second through hole, and the heat-conducting copper sheet is in contact with the heat sink.

Detailed Implementation

[0019] Please see Figure 1-11 A heat-dissipating shipborne central control screen includes a touch screen 110, a display screen 120, a main frame 130, a sealing ring 140, a main control board 150, a rear cover frame 160, a data connector, and a positioning chip box 180, which are installed in sequence. The touch screen 110, the display screen 120, the data connector, and the positioning chip box 180 are connected to the main control board 150 via data cables. The rear cover frame 160 is also provided with symmetrically arranged rectangular heat dissipation slots 163.

[0020] In a preferred embodiment, a heat sink 190 is provided between the main control board 150 and the rear cover frame 160. The heat sink 190 has a cavity 191 for thermal grease. On one side corresponding to the main control board 150, there are evenly distributed cylindrical heat sink fins 192 and strip heat sink fins 193. On the other side, there are rectangular heat sink fins 210 corresponding to the rectangular heat sink 163.

[0021] In a preferred embodiment, the cylindrical heat dissipation fin 192 includes a cylindrical body 195, a contact head 194 is provided on the cylindrical body 195, and a spring 196 is also provided between the contact head 194 and the cylindrical body 195. The contact head 194 can contact the main control board 150 for heat transfer.

[0022] The contact head 194 with spring 196 can adapt to the main control board 150 components or the rear cover frame 160 structure of different heights, and can make full contact between the cylindrical heat dissipation fins 192 and the main control board 150 and the rear cover frame 160 that require heat conduction, so as to meet the heat transfer requirements.

[0023] In the preferred embodiment, the contact head 194 is made of thermally conductive and insulating plastic. This is because the contact head 194 comes into contact with the main control board 150, thus requiring thermal conductivity and insulation.

[0024] In a preferred embodiment, at least two first bosses 134 are provided on the first sidewall 133 of the main frame 130, and fastening holes 135 are provided on the first bosses 134. A second boss 141 is provided on the third sidewall 143 of the sealing ring 140. The second boss 141 has a first through hole 142 with a diameter 0.49 mm larger than the diameter of the first boss 134, and the length of the second boss 141 is 2 mm longer than the length of the first boss 134. A second through hole 161 is provided at a corresponding position on the rear cover frame 160. The diameter of the second through hole 161 is 7.7 mm smaller than the outer diameter of the first boss 134. The main frame 130, the sealing ring 140, and the rear cover frame 160 are connected and fixed by screws passing through the second through hole 161, the first through hole 142, and the fastening holes 135 on the first bosses 134.

[0025] A first through hole 142 is provided on the second boss 141 of the sealing ring 140. During installation, this hole serves as a guide, automatically aligning all remaining holes and eliminating the need for manual alignment. Furthermore, the length of the second boss 141 is greater than the length of the first boss 134, and the diameter of the first boss 134 is greater than the diameter of the second through hole 161. The sealing ring 140 is made of a moderately hard plastic material. During screw tightening, the second through hole 161 of the rear cover frame 160 presses the top surface of the second boss 141 against the top surface of the first boss 134, while simultaneously tightly pressing the periphery of the sealing ring 140 against the periphery of the main frame 130. This lateral compression achieves a waterproof seal.

[0026] In a preferred embodiment, a heat-conducting copper sheet 220 is also provided at the second through hole 161, and the heat-conducting copper sheet is in contact with the heat sink 190.

[0027] The heat sink 190 can transfer heat to the mounting screws through the thermally conductive copper sheet 220, which helps the screws dissipate heat.

[0028] In a preferred embodiment, a third boss 197 is provided on the heat sink 190. The third boss 197 is provided with a third through hole 199 for the data connector to pass through. A sealing ring is provided inside the third through hole 199. An annular groove 198 is provided on the outer surface of the third boss 197. A sealing ring is provided on the annular groove 198.

[0029] The purpose of setting a sealing ring inside the third through hole 199 and setting a sealing ring on the third protrusion 197 is to separate the data connector from the internal space of the heat-dissipating shipboard central control screen. In this way, even if the data connector and the rear cover frame 160 are not sealed tightly, water cannot enter the heat-dissipating shipboard central control screen from the data connector.

[0030] In a preferred embodiment, an annular groove 144 is provided on the third sidewall 143 of the sealing ring 140, and an annular protrusion 136 is provided on the first sidewall 133 of the main frame 130. The annular protrusion 136 can be locked in the annular groove 144.

[0031] This is equivalent to implanting a reinforcing rib into the sealing ring 140, which can improve the life of the sealing ring 140 and change the deformation direction of the sealing ring 140 when subjected to locking pressure. This allows the sealing gaskets on both sides of the annular groove 144 to deform outwards, making the deformation of the sealing gaskets more uniform and improving the waterproof capability of the sealing ring 140 after it is locked.

[0032] In a preferred embodiment, the first boss 134 includes a column 137 and a heat-resistant locking ring 138 assembled on the outside of the column 137. The locking ring 138 is made of stainless steel and has high pressure resistance and high temperature resistance.

[0033] Because the heat generated inside the heat-dissipating marine central control screen is high, sometimes reaching 80°C, the first protrusion 134 will enlarge due to heat, and the fastening hole 135 inside the first protrusion 134 will also enlarge. The fit between the fastening hole 135 and the screw will become loose. Thus, during the vibration of the ship's operation, the fastening screw will gradually loosen in the fastening hole 135, reducing the waterproof capability of the heat-dissipating marine central control screen. By setting a heat-resistant fastening ring 138 on the outer ring of the first protrusion 134, the degree to which the fastening hole 135 inside the first protrusion 134 enlarges after being heated can be reduced, thereby improving the fastening capability and improving the waterproof capability of the second through hole 161 on the rear cover frame 160.

[0034] In a preferred embodiment, a support platform 132 is provided inside the main frame 130, which is lower than the second side wall 131. The depth of the support platform 132 to the second side wall 131 is equal to the thickness of the touch screen 110. The touch screen 110 is mounted on the support platform 132.

[0035] In the preferred embodiment, the touch screen 100, the display screen 200, and the main frame 130 are glued together. When applying the glue, ensure that the bottom edges are evenly coated to ensure that the bonding surface is waterproof.

[0036] In the preferred embodiment, the height of the cylindrical heat sink 192 is greater than the height of the strip heat sink 193, and the contact head 194 on the cylindrical heat sink 192 contacts the main control board 150.

[0037] In a preferred embodiment, the data connector includes one USB interface 610, two CAN interfaces 620, one Ethernet interface 630, one RS232 serial interface 640, one alarm interface 650, and two power interfaces 660, wherein the two power interfaces 660 are 12V / 24V input.

[0038] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
