Description

Technical Field

[0001] This utility model relates to the field of tablet computer technology, and in particular to an industrial tablet computer. Background Technology

[0002] Due to their small size and portability, tablet computers are being used in more and more fields. For example, teachers use tablet computers to teach students; hosts use tablet computers to conduct meetings or events; and factory workers use tablet computers to monitor product production lines.

[0003] Industrial panel PCs are industrial control computers specifically designed for industrial use. Their basic performance and compatibility are almost identical to commercial computers, but industrial panel PCs place greater emphasis on security and stability in different environments, providing the best solutions for human-machine interfaces and production process control.

[0004] Current industrial tablet PCs are used in complex environments. If there is a lot of dust in the factory, this dust can easily enter the computer through the heat dissipation holes on the industrial tablet PC's casing. Dust, especially metallic dust, can easily damage the internal components of the industrial tablet PC, affecting its normal operation. To protect industrial tablet PCs from dust damage, existing industrial tablet PCs often adopt a design approach that sacrifices heat dissipation, such as reducing or even eliminating heat dissipation holes on the casing. While this method can greatly prevent industrial dust from entering the internal parts of the industrial tablet PC, it also reduces the heat dissipation effect. This is especially true in material processing plants involving heat treatment, where the ambient temperature is already high, which can easily cause the internal temperature of the industrial tablet PC to become too high and damage it. Summary of the Invention

[0005] The technical problem this invention aims to solve is: addressing the difficulty of existing industrial tablet PCs in achieving compatibility with heat dissipation and dust prevention.

[0006] To solve the above-mentioned technical problems, this utility model provides an industrial tablet computer, characterized in that the industrial tablet computer comprises:

[0007] A screen assembly, wherein one side of the screen assembly is provided with a display screen for displaying information, and the other side is connected to the internal components of the tablet computer;

[0008] A housing is connected to the other side of the screen assembly, and the connection between the housing and the screen assembly forms a cavity. The internal assembly is located inside the cavity. The housing includes a back panel and a side panel. The side panel is provided with a first heat dissipation hole, and the inner layer of the housing is provided with a second heat dissipation hole. The back panel includes an inner layer and an outer layer. The outer layer, inner layer, and side panel are connected to each other to form a receiving cavity.

[0009] A fan is fixed inside the receiving cavity. Multiple fans are provided, and the multiple fans are located on one side of the housing side plate. The multiple fans are arranged along the direction from the top to the bottom of the housing side plate, and the air outlet direction of the multiple fans is the same as the orientation of the heat dissipation holes of the housing side plate.

[0010] Furthermore, the outer layer of the housing is provided with a third heat dissipation hole, and the second heat dissipation hole on the inner layer of the housing corresponds to the third heat dissipation hole on the outer layer of the housing. The inner layer of the housing and the outer layer of the housing can move relative to each other so that the overlap area S of the second heat dissipation hole on the inner layer of the housing and the third heat dissipation hole on the outer layer of the housing changes.

[0011] Furthermore, a connector is provided between the multiple fans, and the top fan is fixed to the top of the outer layer of the housing by the connector.

[0012] Furthermore, the shell is made of aluminum alloy.

[0013] Furthermore, the inner shell layer, the outer shell layer, and the shell side plate are connected in a detachable manner.

[0014] Furthermore, the internal components include a CPU, a heat sink, and a power supply.

[0015] Furthermore, a vibration damping spring is provided inside the receiving cavity.

[0016] Compared with the prior art, the industrial tablet computer of this utility model has the following advantages:

[0017] This embodiment of the invention features a housing backplate with a receiving cavity containing several fans. The airflow from these fans can alter the direction of industrial dust movement. The receiving cavity, formed by the inner and outer layers of the housing, acts as an air duct for the fans, directing the industrial dust out through the first heat dissipation hole on the housing side plate. The receiving cavity also guides the fan airflow, preventing airflow diffusion and the intrusion of industrial dust into internal components, significantly reducing the amount of industrial dust entering internal components through the inner layer of the housing. In addition to changing the direction of industrial dust, the fans also cool the industrial tablet PC, lowering its overall temperature. Furthermore, this invention does not eliminate the through-holes in the inner layer of the housing to enhance dust prevention; the industrial tablet PC can still reduce the temperature of internal components through the second heat dissipation hole, thus addressing both heat dissipation and dust prevention issues in industrial tablet PCs.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] like Figure 1-5 As shown, this utility model embodiment provides an industrial tablet computer, which includes:

[0032] A screen assembly 100, one side of which is provided with a display screen for displaying information, and the other side is connected to the internal component 300 of the tablet computer;

[0033] A housing 200 is connected to the other side of the screen assembly 100. The housing 200 and the screen assembly 100 are connected to form a cavity 350. The internal assembly 300 is located inside the cavity 350. The housing 200 includes a housing back plate 210 and a housing side plate 240. The housing side plate 240 is provided with a first heat dissipation hole 241. The housing inner layer 220 is provided with a second heat dissipation hole 221. The housing back plate 210 includes a housing inner layer 220 and a housing outer layer 230. The housing outer layer 230, the housing inner layer 220, and the housing side plate 240 are interconnected to form a receiving cavity 400.

[0034] A fan 500 is fixed inside the receiving cavity 400. Multiple fans 500 are provided and are located on one side of the housing side plate 240. The multiple fans 500 are arranged along the direction from the top to the bottom of the housing side plate 240, and the air outlet direction of the multiple fans 500 is the same as the orientation of the heat dissipation holes of the housing side plate 240.

[0035] The screen assembly 100 is the main interactive interface of the industrial panel PC, used to display information and receive user input. It typically consists of a display screen and a touch screen (if touch functionality is supported). One side of the display screen is used to display images and text information, while the other side is connected to the internal assembly 300 and the housing 200.

[0036] The housing 200 is a protective structure for the industrial tablet PC. It is connected to the other side of the screen assembly 100 to form a cavity 350, in which the internal assembly 300 is housed.

[0037] The housing 200 consists of two layers: an inner layer 220 and an outer layer 230. The inner and outer layers 220 are connected to the side plate 240, forming a cavity 400 for housing the fan 500. The inner layer 220 has a second heat dissipation hole 221. Heat generated by the internal components 300 passes sequentially through the internal components 300, the cavity 350, the second heat dissipation hole 221, and the first heat dissipation hole 241. The fan 500 is located inside the cavity 400 and is connected to the inner wall of the outer layer 230. The inner wall of the inner layer 220 provides support for the fan 500. When industrial dust from the factory enters the cavity 400 through the first heat dissipation hole 241, the airflow generated by the fan 500 blows the dust out of the cavity 400 through the first heat dissipation hole 241, thus preventing industrial dust from entering the internal components 300 through the second heat dissipation hole 221. The Fan 500 not only prevents dust but also helps dissipate heat from industrial panel PCs.

[0038] Specifically, the receiving cavity 400 not only houses the fan 500 but also serves as an air duct for the fan 500, guiding airflow out of the first heat dissipation hole 241. If the fan 500 is only installed inside the industrial panel PC, the scattered airflow will not only blow industrial dust out of the first heat dissipation hole 241 but also directly blow dust into the internal components 300. Preferably, the inner layer 220 and the outer layer 230 of the housing are arranged parallel to each other, the side plate 240 of the housing is perpendicular to the inner layer 220, and the orientation of the fan 500 is perpendicular to the side plate 240 of the housing. In this case, the airflow generated by the fan 500 is not obstructed by the interior of the receiving cavity 400, resulting in higher dust removal efficiency.

[0039] This embodiment of the invention features a housing backplate 210 with a receiving cavity 400. Several fans 500 are installed inside the receiving cavity 400. The airflow from these fans 500 can change the direction of industrial dust movement. The receiving cavity 400, formed by the inner housing layer 220 and the outer housing layer 230, acts as an air duct for the fans 500, blowing industrial dust out through the first heat dissipation hole 241 on the housing side plate 240. The receiving cavity 400 also guides the airflow of the fans 500, preventing airflow diffusion and the blowing of industrial dust into the internal components 300, significantly reducing the amount of industrial dust entering the internal components 300 through the inner housing layer 220. The fans 500 not only change the direction of industrial dust but also cool the industrial tablet PC, lowering its overall temperature. Furthermore, this invention does not eliminate the through-holes in the inner housing layer 220 to enhance dust prevention; the industrial tablet PC can still reduce the temperature of the internal components 300 through the second heat dissipation hole 221, thus addressing both heat dissipation and dust prevention issues in industrial tablet PCs.

[0040] like Figure 6-7 As shown, in an optional embodiment of the present invention, the outer shell 230 is provided with a third heat dissipation hole 231, and the second heat dissipation hole 221 on the inner shell 220 corresponds to the third heat dissipation hole 231 on the outer shell 230. The inner shell 220 and the outer shell 230 can move relative to each other so that the overlap area S of the second heat dissipation hole 221 on the inner shell 220 and the third heat dissipation hole 231 on the outer shell 230 changes.

[0041] The relative movement between the inner layer 220 and the outer layer 230 of the housing can be achieved through a sliding rail mechanical structure. This method allows adjustment of the overlap area S between the second heat dissipation hole 221 and the third heat dissipation hole 231 according to the heat generation and heat dissipation requirements of the internal components 300. The overlap area S of the second heat dissipation hole 221 and the third heat dissipation hole 231 refers to the area that can pass through when the heat dissipation holes are opposite each other. The overlap area S is the largest when the heat dissipation holes correspond to each other, and at this time the overlap area S is the area of ​​one of the heat dissipation holes; when the heat dissipation holes are staggered, the overlap area S is the smallest.

[0042] Specifically, when the internal component 300 generates a large amount of heat, the heat dissipation efficiency can be improved by increasing the overlapping area S, allowing heat to pass directly from the second heat dissipation hole 221 through the third heat dissipation hole 231. Conversely, when the heat generation is small and the amount of industrial dust is large, the overlapping area S can be reduced to reduce the amount of industrial dust that directly passes through the second heat dissipation hole 221 and the third heat dissipation hole 231 into the internal component 300.

[0043] In this embodiment of the invention, by adjusting the overlapping area S of the second heat dissipation hole 221 and the third heat dissipation hole 231, users can ensure heat dissipation while also taking into account dust prevention requirements, thus improving the flexibility of the industrial tablet PC.

[0044] In an optional embodiment of this utility model, a connector 600 is provided between the plurality of fans 500, and the top fan 500 is fixed to the top of the outer layer 230 of the housing by the connector 600.

[0045] The connector 600 simplifies the installation process of the fan 500 system. Operators can use the connector 600 to quickly and accurately install multiple fans 500 into the housing 200 without having to secure them individually. Connecting multiple fans 500 into a single unit via the connector 600 makes it easier to achieve coordinated operation between the fans 500. For example, the speed of the fans 500 can be adjusted simultaneously to create a more uniform and efficient airflow distribution, thereby improving heat dissipation efficiency.

[0046] In an optional embodiment of this utility model, the housing 200 is made of aluminum alloy.

[0047] Specifically, aluminum alloy was chosen as the structural material for the housing 200 based on its numerous superior properties. Aluminum alloy not only possesses high strength and lightweight characteristics, making the entire industrial panel PC both robust and easy to carry and operate, but it also exhibits excellent thermal conductivity. This property, combined with the heat dissipation holes in the housing 200 design, can more effectively help dissipate heat from the internal components 300, avoiding overheating problems, thereby ensuring stable operation of the industrial panel PC and extending its service life.

[0048] Furthermore, aluminum alloys offer high resistance to corrosion and oxidation, which is particularly important in industrial environments where adverse conditions such as humidity and corrosive gases may be encountered. This protects the internal components from external environmental damage, enhancing the overall durability and reliability of the tablet PC.

[0049] In an optional embodiment of this utility model, the inner shell layer 220, the outer shell layer 230, and the shell side plate 240 are connected in a detachable manner.

[0050] The inner shell layer 220, outer shell layer 230, and shell side plate 240 are connected by threads and screws, achieving a detachable connection. This allows workers to easily disassemble and reinstall the various components without damaging the structure of the shell 200.

[0051] In this invention, the detachable connection method improves the ease of maintenance and flexibility of the industrial panel PC.

[0052] In an optional embodiment of this utility model, a vibration damping spring is provided inside the receiving cavity 400.

[0053] Among them, the vibration damping spring has good elasticity. When the industrial tablet computer is subjected to vibration or impact, the spring can absorb and disperse this energy, thereby reducing the vibration amplitude and impact force transmitted to the internal components 300.

[0054] Specifically, the number and location of damping springs should be determined based on the size and weight of the industrial panel PC and the expected operating environment. Generally, damping springs can be installed at the four corners or critical locations of the housing 400 to ensure all-around vibration damping protection.

[0055] In this invention, by setting a damping spring in the receiving cavity 400, combined with the inner and outer layer design of the shell 200, the vibration damping performance of the industrial tablet PC in complex environments can be significantly improved.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
