Description

Technical Field

[0001] This utility model relates to the field of industrial electronic equipment protection technology, specifically to a waterproof shell for an industrial tablet computer. Background Technology

[0002] Industrial panel PCs are key devices in industrial automation, intelligent manufacturing, and outdoor operations, requiring stable operation in complex environments such as dust, humidity, and vibration. Waterproofing is one of the core indicators for ensuring reliable operation, and the casing, as the first line of defense, directly affects the device's waterproof rating and lifespan.

[0003] Currently, most waterproof casings for industrial tablet PCs use traditional sealing structures, typically achieving a tight seal between the bottom shell and the front panel using a single sealing ring.

[0004] In terms of heat dissipation, industrial panel PCs generate a lot of heat when operating under high loads, and sealed casings often sacrifice heat dissipation efficiency to ensure waterproofing. Existing casings have relatively simple heat dissipation structures, relying mainly on the casing itself for heat dissipation, which makes it difficult to quickly dissipate internal heat. This can easily cause the device to experience performance degradation and crashes due to overheating, especially when operating in high-temperature environments. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a waterproof casing for industrial tablet PCs, solving the problems of unstable waterproof performance and low heat dissipation efficiency in existing waterproof casings for industrial tablet PCs.

[0006] To achieve the above objectives, this utility model provides a waterproof housing for an industrial tablet PC, comprising a housing, a bottom shell and a front panel, the front panel having mounting holes for mounting a display screen, an annular groove on the mounting surface of the bottom shell, an annular skirt fixedly mounted on the mounting surface of the front panel, a sealing ring fixedly mounted on the mounting surface of the front panel and fitted onto the annular skirt, a heat-conducting component on the housing, and a suspended support component at the rear end of the housing.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Preferably, the heat-conducting component includes a heat-conducting plate fixedly disposed on the inner wall of the front panel, the heat-conducting plate being provided with heat-conducting protrusions corresponding to the heat-generating components of the tablet computer, and an array of heat dissipation fins disposed on the outer side of the outer shell, the array of heat dissipation fins penetrating the front panel and connected to the heat-conducting plate.

[0009] Preferably, the rear end of the bottom shell is symmetrically provided with a storage groove, the inside of the storage groove is rotatably connected with a rotating shaft, the inside of the storage groove is provided with a support leg, the support leg is provided with an adjustment groove, and the rotating shaft passes through the adjustment groove.

[0010] Preferably, the rear end of the bottom shell is provided with a limiting groove that communicates with the storage slot. The limiting groove is adapted to the shape of the support leg. When one end of the support leg is located in the limiting groove, the outer wall of the support leg fits against the inner wall of the limiting groove to fix the angle of the support leg.

[0011] Preferably, a permanent magnet is fixedly connected to the inner wall of the storage slot on the side away from the pivot, and the permanent magnet is magnetically connected to the support leg.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By guiding the annular skirt plate and the annular groove, and by tightly squeezing and sealing the sealing ring fitted on the annular skirt plate, water intrusion is effectively prevented, thus solving the problem of unstable waterproof performance of existing shells.

[0014] The heat-conducting plate, heat-conducting boss, and array of heat dissipation fins in the heat-conducting components work together to quickly conduct and dissipate the heat generated by the heat-generating components of the tablet computer, preventing the device from affecting performance due to overheating;

[0015] The support legs of the suspended support assembly are angled through a pivot and adjustment groove, and fixed by a limiting groove. When stored, they are fixed by permanent magnets. This solves the problems of inconvenient adjustment, insufficient stability and large storage space of existing support structures. At the same time, the suspended support can avoid direct contact with the placement surface, thereby reducing the possibility of industrial tablet computers coming into contact with water sources when placed, and achieving waterproofing of industrial tablet computers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this embodiment provides a waterproof housing for an industrial tablet PC, including a housing 1. The housing 1 includes a bottom shell 101 and a front panel 102. The front panel 102 is provided with mounting holes 2 for mounting a display screen. The mounting holes 2 can accurately position the display screen, ensuring stable installation and normal display. An annular groove 3 is formed on the mounting surface of the bottom shell 101. An annular skirt 4 is fixedly provided on the mounting surface of the front panel 102. The annular skirt 4 and the annular groove 3 cooperate with each other to provide precise guidance for the assembly of the bottom shell 101 and the front panel 102, ensuring the accuracy of the assembly. A sealing ring 5 is fixedly provided on the mounting surface of the front panel 102. The sealing ring 5 is sleeved on the annular skirt 4. When the bottom shell 101 and the front panel 102 are assembled, the sealing ring 5 is tightly squeezed between the annular skirt 4 and the annular groove 3, effectively preventing moisture from entering the interior of the housing 1 from the assembly gap, significantly improving the waterproof performance of the housing. The housing 1 is equipped with a heat conduction component 6, which is used to quickly dissipate the heat generated by the industrial tablet computer during operation. The rear end of the housing 1 is equipped with a suspension support component 7, which enables the housing to be suspended at multiple angles to adapt to different usage scenarios.

[0024] In summary, the improvement of this embodiment lies in the fact that the cooperation and guidance between the annular skirt plate 4 and the annular groove 3, as well as the tight compression and sealing of the sealing ring 5 sleeved on the annular skirt plate 4, effectively prevent water intrusion and solve the problem of unstable waterproof performance of the existing shell.

[0025] Based on the above, other structures also need to be disclosed in detail, such as:

[0026] The heat-conducting component 6 includes a heat-conducting plate 601 fixedly disposed on the inner wall of the front panel 102. The heat-conducting plate 601 can absorb the heat emitted by the tablet computer over a large area. The heat-conducting plate 601 is provided with heat-conducting protrusions 602 corresponding to the heat-generating components of the tablet computer. The heat-conducting protrusions 602 can be precisely aligned with the heat-generating components, efficiently conducting the concentrated heat to the heat-conducting plate 601. An array of heat dissipation fins 603 is disposed on the outer side of the outer shell. The array of heat dissipation fins 603 penetrates the front panel 102 and connects to the heat-conducting plate 601. The heat absorbed by the heat-conducting plate 601 is quickly dissipated to the external environment through the heat dissipation fins, improving heat dissipation efficiency.

[0027] The rear end of the bottom shell 101 is symmetrically provided with storage slots 701, which provide storage space for the support legs 703, reducing the space occupied by the shell when the support function is not used. A rotating shaft 702 is rotatably connected inside the storage slot 701, and the support legs 703 are set inside the storage slot 701. An adjustment slot 704 is provided on the support legs 703, and the rotating shaft 702 passes through the adjustment slot 704. The cooperation between the rotating shaft 702 and the adjustment slot 704 allows the support legs 703 to rotate around the rotating shaft 702. At the same time, the adjustment slot 704 provides a certain amount of movement space for the rotation of the support legs 703, which facilitates the angle adjustment of the support legs 703.

[0028] The rear end of the bottom shell 101 is provided with a limiting groove 705 that communicates with the storage groove 701. The limiting groove 705 is adapted to the shape of the support leg 703. When one end of the support leg 703 is located in the limiting groove 705, the outer wall of the support leg 703 fits against the inner wall of the limiting groove 705 to fix the angle of the support leg 703 and ensure the stability of the support.

[0029] A permanent magnet 706 is fixedly connected to the inner wall of the storage groove 701 on the side away from the rotating shaft 702. The permanent magnet 706 is magnetically connected to the support leg 703. When the support leg 703 is stored in the storage groove 701, the permanent magnet 706 can firmly attract and fix the support leg 703, preventing the support leg 703 from falling out of the storage groove 701 during movement or vibration.

[0030] In summary, the working principle of this solution is as follows:

[0031] When the industrial panel PC is working, the heat generated by the heat-generating components is transferred to the heat-conducting boss 602 through the heat-conducting silicone pad on the surface of the heat-conducting boss 602, and then conducted by the heat-conducting boss 602 to the heat-conducting plate 601. The heat absorbed by the heat-conducting plate 601 is conducted to the array of heat dissipation fins 603 that penetrate the front panel 102. The heat dissipation fins exchange heat with the outside air and dissipate the heat into the air to achieve heat dissipation.

[0032] Support adjustment process: When suspension support is required, the support leg 703 is removed from the storage slot 701. The support leg 703 rotates around the pivot 702, which moves within the adjustment slot 704. One end of the support leg 703 is rotated into the limiting slot 705 corresponding to the desired angle. The outer wall of the support leg 703 fits against the inner wall of the limiting slot 705, thus fixing the support angle. The outer shell is suspended and supported by the support leg 703. When support is not needed, the support leg 703 is rotated out of the limiting slot 705 and into the storage slot 701. The support leg 703 is magnetically attracted to the permanent magnet 706 on the inner wall of the storage slot 701, thus securing the support leg 703 in place.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
