Description

Technical Field

[0001] This utility model relates to the field of computer technology, and in particular to a ruggedized portable information terminal device. Background Technology

[0002] Rugged portable information terminals are customized electronic devices based on system requirements, integrating information processing modules, information display components, touch modules, and built-in speaker modules. They support embedded operating systems and can display various information formats on the terminal screen, including text, tables, images, engineering graphics, sound, video, animation, and 3D graphics.

[0003] Traditional ruggedized portable information terminals typically use sheet metal casings, which only protect the internal components. The heat generated by these components cannot dissipate quickly enough, resulting in poor temperature adaptability. Therefore, this application provides a ruggedized portable information terminal device with high heat dissipation efficiency and the ability to adapt to a wide temperature range. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a ruggedized portable information terminal device, comprising:

[0005] The lower frame has a heat-conducting block connected inside and several heat dissipation fins arranged horizontally connected to the outside of the lower frame.

[0006] A panel is fixedly mounted on the upper side of the lower frame and is sealed to the lower frame to form a cavity;

[0007] The display and control module and the pressure strip are used to fix the display and control module to the lower side of the panel.

[0008] The main control module is fixedly installed inside the lower frame and is attached to the heat-conducting block.

[0009] The battery module is fixedly installed in the lower frame and arranged side by side with the main control module.

[0010] In some embodiments, the lower frame and / or panel are provided with a sealing groove, and a sealing strip for sealing is provided in the sealing groove.

[0011] In some embodiments, connecting screws are also included, by which the lower frame and the panel are fixedly connected.

[0012] In some embodiments, pressure strips are symmetrically arranged on both sides of the display and control module.

[0013] In some embodiments, a thermally conductive pad and a pressure block are also included. The pressure block is placed above the battery module and fixedly connected to the lower frame to fix the battery module inside the lower frame. The thermally conductive pad is placed below the battery module and is attached to the battery module through the pressure block to conduct the heat generated by the battery module to the lower frame.

[0014] In some embodiments, the lower frame has a power interface, an Ethernet interface, a USB interface and a device debugging interface on its side.

[0015] In some embodiments, the display and control module includes a display screen, a shielding film, and a touch screen arranged sequentially from bottom to top, with an adhesive layer for buffering and vibration isolation provided between the display screen and the shielding film, and between the shielding film and the touch screen.

[0016] In some implementations, the main control module is fixed to the lower frame with screws.

[0017] In some implementations, the panel is secured to the lower frame with screws.

[0018] In some implementations, corner protectors are also included, which are fixedly disposed at the four corners of the lower frame and the panel.

[0019] Compared with existing technologies, the ruggedized portable information terminal device provided in this application improves heat dissipation efficiency by placing a heat-conducting block on the inner bottom of the lower frame. This heat-conducting block effectively transfers heat generated by the main control module to the lower frame, where multiple heat dissipation fins on the outer side evenly distribute the transferred heat. Furthermore, the horizontally positioned heat dissipation fins increase the effective heat exchange area, thereby increasing the convective heat transfer coefficient and reducing contact thermal resistance. The irregular surface effectively disrupts the laminar flow boundary near the wall, further enhancing convective heat transfer. Therefore, the ruggedized portable information terminal provided in this application exhibits excellent heat dissipation performance and can adapt to a wide range of operating environments.

[0026] like Figures 1-3 As shown, the ruggedized portable information terminal device provided by this utility model includes:

[0027] The lower frame 1 has a heat-conducting block 11 connected inside and a number of heat dissipation fins 12 arranged in a horizontal direction connected outside.

[0028] Panel 2 is fixedly disposed on the upper side of the lower frame 1 and is sealed to the lower frame 1 to form a cavity;

[0029] The display and control module and the pressure strip 4 are used to fix the display and control module to the lower side of the panel 2.

[0030] The main control module 5 is fixedly disposed inside the lower frame 1 and is attached to the heat-conducting block 11;

[0031] Battery module 6 is fixedly installed in the lower frame 1 and arranged in parallel with the main control module 5.

[0032] In the above embodiments, by setting a heat-conducting block 11 at the bottom inner side of the lower frame 1, the heat generated by the main control module can be promptly conducted to the lower frame 1. Then, multiple heat dissipation fins 12 set on the outer side of the lower frame 1 evenly distribute the conducted heat, thereby effectively improving heat dissipation efficiency. Furthermore, the heat dissipation fins 12 arranged horizontally can increase the effective heat exchange area, thereby increasing the convective heat transfer coefficient of the object surface and reducing contact thermal resistance. The irregular surface can effectively disrupt the laminar flow boundary near the wall, further enhancing convective heat transfer. Simultaneously, the rational layout of the various components inside the cavity of the information terminal device further ensures the heat dissipation efficiency of the information terminal device. Therefore, the ruggedized portable information terminal provided in this application has extremely excellent heat dissipation performance and can adapt to a wide range of operating environments.

[0033] like Figure 2 As shown, in some embodiments, the lower frame 1 and / or panel 2 are provided with a sealing groove 7, and a sealing strip 8 for sealing is provided in the sealing groove 7.

[0034] In the above embodiment, a connecting screw 9 is provided between the lower frame 1 and the panel 2 to fix the lower frame 1 and the panel 2 together. By providing a sealing groove 7 and a sealing strip 8 on the lower frame 1 and / or the panel 2, the sealing performance between the lower frame 1 and the panel 2 is ensured, thus guaranteeing the overall performance of the information terminal device. It should be noted that in this embodiment, when the sealing groove 7 is provided on the lower frame 1, the connecting screw 9 on the panel 2 is positioned relative to the sealing groove 7 on the edge side of the panel 2; when the sealing groove 7 is provided on the panel 2, the connecting screw 9 on the panel 2 is positioned relative to the sealing groove 7 on the center side of the panel 2.

[0035] In some embodiments, pressure strips 4 are symmetrically arranged on both sides of the display and control module.

[0036] In the above embodiments, pressure strips 4 are provided on both sides of the display and control module. The pressure strips 4, which are symmetrically arranged, can effectively fix the display and control module in the lower frame 1, ensuring the stability of the display and control module.

[0037] In some embodiments, a pressure block 13 and a thermal pad 14 are also included. The pressure block 13 is placed above the battery module 6 and fixedly connected to the lower frame 1 to fix the battery module 6 inside the lower frame 1. The thermal pad 14 is placed below the battery module 6 and is attached to the battery module 6 through the pressure block 13 to conduct the heat generated by the battery module 6 to the lower frame 1.

[0038] In the above embodiment, the pressure block 13 can effectively fix the battery module 6 in the lower frame 1, while the heat-conducting pad 14 can effectively conduct the heat generated by the battery module 6 to the lower frame 1 in a timely manner, and then the heat dissipation fins 12 provided on the outside of the lower frame 1 can dissipate the heat, further ensuring the heat dissipation efficiency of the information terminal device.

[0039] In some embodiments, the lower frame 1 has a power interface, an Ethernet interface, a USB interface and a device debugging interface on its side.

[0040] In the above embodiment, the panel 2 is also provided with a number of function buttons 10, and the side of the lower frame 1 is also provided with a power button. By providing a power interface, an Ethernet interface, a USB interface, a debugging interface and a power button on the side of the lower frame 1, and providing function buttons 10 on the panel 2, the normal operation of the information terminal device is ensured.

[0041] In some embodiments, the display and control module includes a display screen 31, a shielding film 32, and a touch screen 33 arranged sequentially from bottom to top. An adhesive layer for buffering and vibration isolation is provided between the display screen 31 and the shielding film 32, and between the shielding film 32 and the touch screen 33.

[0042] In the above embodiments, by providing an adhesive layer between the display screen 31 and the shielding film 32 and between the shielding film 32 and the touch screen 33, the damping effect of the adhesive layer can effectively reduce the vibration and impact energy transmitted from the system to the touch screen 33, thereby reducing the stress transmitted from the system to the display screen 31, reducing the strain of the display screen 31, greatly improving the mechanical resistance of the display control module, and achieving effective protection of the display control module screen.

[0043] In some embodiments, the main control module 5 is fixed to the lower frame 1 with screws; the panel 2 is fixed to the lower frame 1 with screws.

[0044] In the above embodiments, the main control module 5 and the panel 2 are fixedly connected to the lower frame 1 by screws, thereby ensuring the stable and reliable connection between the components.

[0045] In some embodiments, corner protectors 10 are also included, which are fixedly disposed at the four corners of the lower frame 1 and the panel 4.

[0046] In the above embodiments, by providing corner protectors 10 at each of the four corners of the lower frame 1 and the panel 2, the components inside the cavity formed by the lower frame 1 and the panel 2 are effectively protected based on the corner protectors 10.
