Description

Technical Field

[0001] This invention relates to the field of industrial display technology, specifically to an industrial display. Background Technology

[0002] Industrial displays are widely used in harsh environments such as CNC machine tools, power monitoring, mines, and food processing. To achieve dustproof ratings, traditional displays often employ a fully enclosed, fanless design. However, heat generated by internal components such as the driver board and backlight module cannot be effectively dissipated, leading to high-temperature aging of the screen, touch response drift, and in severe cases, capacitor failure on the driver board. A few products have ventilation holes on the back and dust filters, but these filters are prone to clogging, difficult to clean, and dust can still enter the interior through the fan shaft seal.

[0003] Furthermore, most existing monitors have an integrated structure. If any component, such as the internal power board, motherboard, or display panel, fails, the entire unit must be disassembled or even scrapped. On-site repairs require power disconnection, opening the cover, reapplying thermal grease, and resealing, which is time-consuming, labor-intensive, and can easily compromise protective performance. In industrial settings, equipment downtime results in significant losses.

[0004] To address the aforementioned issues, there is a need for an industrial display that can achieve efficient heat dissipation without sacrificing the overall dust protection capability, and also supports rapid modular repair on-site. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention discloses an industrial display. The technical solution adopted is that a mounting groove is provided on the back of the front housing, a tempered glass touch screen is sealed and mounted at the front of the mounting groove, and a liquid crystal display module is mounted in the mounting groove at the rear of the tempered glass touch screen. A heat conduction frame, a hybrid connector plug, and a sealing insertion groove are fixedly connected to the back of the liquid crystal display module. The hybrid connector plug is electrically connected to the liquid crystal display module, and the sealing insertion groove is located around the hybrid connector plug. A rear housing is sealed and covered on the rear side of the front housing, and a rear heat dissipation fin is fixedly connected to the back of the rear housing. A fastening cavity is opened on the front, and the fastening cavity is sealed and fastened to the mounting... On the groove, a through hole is provided in the middle of the rear housing. Screw posts are fixedly connected to the back of the rear housing around the through hole. The main drive module box is fixedly connected to the back of the rear housing by screws. The screws are fixedly connected to the screw posts. A top pressure post is fixedly connected to the bottom of the snap-fit ​​cavity. The top pressure post presses against the back of the liquid crystal display module. The heat conduction bracket is attached to the bottom of the snap-fit ​​cavity. Sealing connectors are fixedly connected to the bottom of the snap-fit ​​cavity around the through hole. A hybrid connector socket is electrically connected to the back of the main drive module box. The hybrid connector socket is located in the through hole and is plugged into the hybrid connector plug. The sealing connector is plugged into the sealing connector groove.

[0006] In a preferred embodiment of the present invention, a fixing lug is fixedly connected to the side of the main drive module box, and screws are tightened one-to-one onto the fixing lug and screw posts. A fastening plate is fixedly connected to the lower part of the main drive module box, and the outer fastening plate presses against the bottom of the rear housing and is fixedly connected by screws. A drive heat dissipation fin is fixedly connected to the front of the main drive module box, and the power cord of the main drive module box extends from the front and is sealed. This structure allows the main drive module box to be stably and compactly installed on the rear housing, and the drive heat dissipation fin can further assist the heat dissipation of the drive module box itself.

[0007] In a preferred embodiment of the present invention, the main drive module box integrates a system motherboard, a power board, and an interface conversion board. This highly integrated modular design allows each drive unit to operate independently, facilitating replacement and simplifying internal wiring.

[0008] In a preferred embodiment of the present invention, a soft metal thermally conductive pad is further provided between the front housing and the rear housing. This helps to further improve the thermal conductivity between the front and rear housings, while also enhancing the sealing effect.

[0009] In a preferred embodiment of the present invention, the inner walls of both the mounting groove and the snap-fit ​​cavity are coated with a moisture-absorbing coating or contain a desiccant packet. This helps absorb residual moisture inside, prevents condensation in environments with large temperature differences, and protects the internal electronic components.

[0010] In a preferred embodiment of the present invention, the heat-conducting frame is made of copper. Copper has excellent thermal conductivity, enabling it to quickly conduct heat from the liquid crystal display module to the rear housing.

[0011] In a preferred embodiment of the present invention, the sealing groove and the sealing connector are made of rubber and have a labyrinthine sealing structure. This multi-layered labyrinthine sealing structure can greatly improve the waterproof and dustproof rating of the hybrid connector's mating joint, meeting the high sealing requirements of industrial environments.

[0012] The beneficial effects of this invention are as follows: This invention integrates core drive components such as the system motherboard, power board, and interface conversion board into an independent main drive module box, and utilizes a hybrid connector plug and socket to achieve pluggable electrical connection. When a drive component malfunctions or requires performance upgrade, the operator only needs to unscrew the fixing screws to remove and replace the entire main drive module box from the rear housing, without disassembling the sealing structure between the front and rear housings. This method significantly simplifies the maintenance process, greatly reduces equipment downtime, and lowers after-sales maintenance costs. The corresponding plug-in joints around the through holes and the corresponding plug-in slots, using a rubber labyrinth sealing structure, effectively prevent dust and moisture from seeping in along the electrical connection channels. The heat generated by the LCD module is directly conducted to the bottom of the locking cavity of the rear housing through the copper heat conduction frame, and then quickly dissipated to the external environment through the rear heat dissipation fins; the main drive module box itself is independently equipped with drive heat dissipation fins, enabling the heat from high-power drive components to be dissipated in a timely manner. At the same time, the soft metal thermal pad between the front and rear housings further enhances the overall thermal conductivity of the structure. This heat dissipation structure design effectively avoids internal heat accumulation, ensuring long-term stable operation under high load conditions. Attached Figure Description

Detailed Implementation

[0019] Example 1

[0020] like Figures 1 to 5As shown, this invention is an industrial display, comprising a front housing 1 and a rear housing 2 that is sealed and closed at the rear. A mounting groove 101 is provided on the back of the front housing 1. A reinforced glass touchscreen 5 is sealed and mounted at the front of the mounting groove 101, and a liquid crystal display module 6 is mounted in the rear of the mounting groove 101. A heat-conducting bracket 7 made of copper is fixedly connected to the back of the liquid crystal display module 6, and a hybrid connector plug 8 electrically connected thereto is also fixedly connected. A sealing insertion groove 9 made of rubber and having a labyrinthine sealing structure is provided around the hybrid connector plug 8.

[0021] The rear housing 2 has a rear heat dissipation fin 3 integrally formed or fixedly connected to its back side, and a snap-fit ​​cavity 203 is provided on its front side. When the rear housing 2 is closed on the front housing 1, the snap-fit ​​cavity 203 is sealed and snapped onto the mounting groove 101. A top pressure post 204 is fixedly connected to the bottom of the snap-fit ​​cavity 203. A through hole 201 is provided in the middle of the rear housing 2, and screw posts 202 are fixedly connected to the back of the rear housing 2 around the through hole 201. A sealing plug 10 (with a labyrinthine sealing structure) is fixedly connected to the bottom of the snap-fit ​​cavity 203 around the through hole 201.

[0022] After the rear housing 2 and the rear housing 1 are assembled, the top pressure post 204 presses against the back of the LCD module 6, and the heat conduction bracket 7 fits tightly against the bottom of the fastening cavity 203. At the same time, the sealing connector 10 is inserted into the sealing connector groove 9 to form a labyrinth seal.

[0023] The main drive module box 4 is detachably fixed to the back of the rear housing 2 via screws 402. Specifically, the main drive module box 4 has a fixing ear plate 401 on its side and a fastening plate 403 at its bottom. The screws 402 pass through the fixing ear plate 401 and are tightened onto the screw post 202, while the fastening plate 403 presses against the bottom of the rear housing 2 and is fixed by the screws 402. The main drive module box 4 integrates the system motherboard, power board, and interface conversion board. A hybrid connector socket 11 is electrically connected to the back of the main drive module box 4, and the hybrid connector socket 11 is directly opposite and located in the through hole 201. When the main drive module box 4 is installed in place, the hybrid connector socket 11 and the hybrid connector plug 8 automatically align and plug in to achieve electrical connection. A drive heat sink fin 404 is also fixedly connected to the front of the main drive module box 4, and its power cord 405 extends from the front and is sealed.

[0024] During operation, the heat generated by the LCD module 6 is conducted to the rear housing 2 through the copper heat conduction frame 7, and then dissipated through the rear heat dissipation fins 3. The heat generated by the main drive module box 4 is dissipated through the drive heat dissipation fins 404. A soft metal thermal pad is provided between the front housing 1 and the rear housing 2 to assist in heat dissipation and sealing. The inner walls of the mounting groove 101 and the snap-fit ​​cavity 203 are coated with a moisture-absorbing coating to prevent condensation.

[0025] When the main drive module box 4 malfunctions or requires an upgrade, simply unscrew screw 402 to remove the entire main drive module box 4 without damaging the seal between the front and rear housings. After repair or replacement, the process can be reversed for quick restoration, ensuring the industrial-grade protection performance of the display remains unaffected.
