Description

Technical Field

[0001] This utility model relates to the field of Internet of Things (IoT) gateway technology, and in particular to an IoT gateway device. Background Technology

[0002] In the construction of industrial IoT and smart cities, gateway devices are key nodes connecting terminal sensors and cloud platforms, and their stable operation is crucial. With the development of 5G and edge computing technologies, the computing load of gateway devices continues to increase, leading to a significant increase in heat generation. Especially in harsh industrial environments, factors such as high temperature and dust affect the reliability and service life of gateways, making it urgent to develop gateway devices with efficient heat dissipation and dust prevention capabilities.

[0003] Currently, most IoT gateways on the market adopt passive heat dissipation design. Common structures include metal casing for auxiliary heat dissipation and heat sink fins for natural convection. Dust prevention measures are mostly fixed dust filters, which require stopping the machine and disassembling the casing for cleaning. The installation method generally uses screws for direct fixation, and re-drilling is required to adjust the position.

[0004] Existing gateway devices suffer from heat dissipation efficiency degradation during long-term operation. Due to the lack of effective dustproof design and uniform heat dissipation, dust accumulation in the heat dissipation channels increases thermal resistance after prolonged operation, leading to an increase in the operating temperature of core components. This continuous deterioration in heat dissipation performance affects the reliability and lifespan of IoT nodes. Therefore, an IoT gateway device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an Internet of Things gateway device, which aims to improve the situation where, due to the lack of effective dustproof design and uniform heat dissipation, dust accumulation in the heat dissipation channel increases thermal resistance after the device has been running for a long time.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an Internet of Things gateway device, including a connector, a gateway housing slidably connected to the inner wall of the connector, a gateway body fixedly connected to the inner wall of the gateway housing, an antenna fixedly connected to the outer wall of the gateway body, a dustproof plate one and a dustproof plate two slidably connected to the inner wall of the gateway housing, and a heat dissipation component provided on the inner wall of the gateway housing.

[0007] The heat dissipation assembly includes a cooling fan, a distribution plate, a heat conduction plate, and a heat sink. The outer wall of the cooling fan is fixedly connected to the inner wall of the gateway housing, the outer wall of the distribution plate is fixedly connected to the inner wall of the gateway housing, the upper surface of the heat conduction plate is fixedly connected to the lower surface of the gateway body, and the outer wall of the heat sink is fixedly connected to the inner wall of the heat conduction plate.

[0008] Furthermore, a fixing block is fixedly connected to the outer wall of the gateway housing, and a screw is slidably connected to the inner wall of the fixing block.

[0009] Furthermore, a nut is threaded onto the outer wall of the screw, and a connecting rod is rotatably connected to the inner wall of the screw.

[0010] Furthermore, the outer wall of the connecting rod is fixedly connected to the inner wall of the second fixing block, and the lower surface of the second fixing block is fixedly connected to the upper surface of the connecting seat.

[0011] Furthermore, a slide rail is fixedly connected to the upper surface of the connecting seat, and a connecting block is slidably connected to the outer wall of the slide rail.

[0012] Furthermore, the outer wall of the connecting block is fixedly connected to the inner wall of the gateway housing, and a clamping plate is slidably connected to the outer wall of the connecting block.

[0013] Furthermore, a second rubber pad is fixedly connected to the outer wall of the clamping plate, and a telescopic rod and a spring are fixedly connected to the outer wall of the second rubber pad.

[0014] Furthermore, a rubber pad is fixedly connected to one end of the telescopic rod and the spring, and the outer wall of the rubber pad is fixedly connected to the inner wall of the connecting seat.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the heat generated by the gateway body is conducted to the heat sink through the heat conduction plate to expand the heat dissipation area. The cold air introduced by the cooling fan is filtered by the second dustproof plate and then guided to the left and right by the diversion plate to achieve uniform coverage of the heat dissipation components by the cold air. With the help of the ventilation holes to exhaust the hot air, the heat dissipation efficiency is improved. The first dustproof plate and the second dustproof plate can be slidably removed, which can clean the intercepted dust regularly to avoid blockage of the heat dissipation channel. At the same time, it prevents dust from entering the interior of the gateway, reduces the failure of components due to dust accumulation or high temperature, and extends the stable operation time of the equipment.

[0017] 2. In this utility model, during installation, the connecting block can be quickly aligned by sliding along the slide rail. The clamping plate automatically completes the initial positioning with the help of the spring and the elastic force of the telescopic rod, without the need for complicated calibration. Then, the screw and the groove of the fixing block are matched and the nut is tightened to achieve secondary fixation. The whole installation process is convenient and fast. The anti-slip pad under the connecting seat further prevents displacement and ensures that the equipment is stably fixed in the vibrating or collision environment, thus improving the installation firmness.

[0025] 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.

[0026] Reference Figures 1-3 This utility model provides an embodiment of an Internet of Things (IoT) gateway device, including a connector 1, a gateway housing 2 slidably connected to the inner wall of the connector 1, a gateway body 5 fixedly connected to the inner wall of the gateway housing 2, and an antenna 4 fixedly connected to the outer wall of the gateway body 5. The antenna 4 is used for wireless signal transmission and reception of the IoT gateway device, ensuring that the gateway body 5 can communicate wirelessly with external devices or networks and ensuring smooth data transmission. Dustproof plate 1 3 and dustproof plate 2 13 are slidably connected to the inner wall of the gateway housing 2. Dustproof plate 1 3 is installed at the ventilation hole of the gateway housing 2 and can block dust from entering the device from the ventilation hole. Dustproof plate 2 13 is located on the air intake path of the cooling fan 17 and can intercept dust in the external cold air to prevent dust from entering the device. Both adopt a slidable and detachable structure for easy cleaning or replacement and to avoid dust blockage affecting heat dissipation. The inner wall of the gateway housing 2 is provided with heat dissipation components.

[0027] The heat dissipation assembly includes a cooling fan 17, a distribution plate 16, a heat conduction plate 14, and a heat sink 15. The outer wall of the cooling fan 17 is fixedly connected to the inner wall of the gateway housing 2. The outer wall of the distribution plate 16 is fixedly connected to the inner wall of the gateway housing 2. The distribution plate 16 can guide the cold air blown directly by the cooling fan 17 to the left and right sides to disperse it, so that the cold air evenly covers the gateway body 5 and the heat dissipation components, achieving uniform heat dissipation. The upper surface of the heat conduction plate 14 is fixedly connected to the lower surface of the gateway body 5. The outer wall of the heat sink 15 is fixedly connected to the inner wall of the heat conduction plate 14. The heat sink 15 is connected to the heat conduction plate 14. By increasing the heat dissipation area, the heat conducted by the heat conduction plate 14 is quickly dissipated into the air, enhancing the heat dissipation effect. A fixing block 10 is fixedly connected to the outer wall of the gateway housing 2. The fixing block 10 is fixed on the gateway housing 2 and has grooves on all four sides to accommodate the screw 8. The screw 8 and nut 9 are used to achieve secondary positioning to prevent the equipment from falling and being damaged due to contact. The screw 8 is slidably connected to the inner wall of the fixing block 10.

[0028] Reference Figures 1-5 A nut 9 is threaded onto the outer wall of the screw 8, and a connecting rod 11 is rotatably connected to the inner wall of the screw 8. The connecting rod 11 serves as the rotation axis of the screw 8, allowing the screw 8 to rotate around it and facilitating its sliding into or out of the groove of the fixing block 10. The outer wall of the connecting rod 11 is fixedly connected to the inner wall of the fixing block 12. The lower surface of the fixing block 12 is fixedly connected to the upper surface of the connecting seat 1. A slide rail 7 is fixedly connected to the upper surface of the connecting seat 1, providing a sliding track for the connecting block 6. This allows for the quick installation and positioning of the gateway housing 2 in conjunction with the connecting block 6. The connecting block 6 is slidably connected to the outer wall of the slide rail 7, and the outer wall of the connecting block 6 is fixedly connected to the inner wall of the gateway housing 2. A clamping plate 18 is connected. The clamping plate 18, through the rubber pad 22 on it, works with other components to compress the telescopic rod 20 and the spring 21, thereby adaptively limiting the gateway housing 2 and achieving initial fixation. The outer wall of the clamping plate 18 is fixedly connected to the rubber pad 22. The outer wall of the rubber pad 22 is fixedly connected to the telescopic rod 20 and the spring 21. The telescopic rod 20 and the spring 21 cooperate to extend and retract when compressed by the clamping plate 18, providing guidance for the deformation of the spring 21, preventing the spring 21 from twisting, and ensuring that the spring 21 can stably generate a rebound force. One end of the telescopic rod 20 and the spring 21 is fixedly connected to a rubber pad 19. The outer wall of the rubber pad 19 is fixedly connected to the inner wall of the connecting seat 1.

[0029] Working principle: When using the IoT gateway device, the gateway body 5 inside the gateway housing 2 generates heat during operation. The heat is first conducted to the heat sink 15 through the heat conduction plate 14, and then dissipated by the heat sink 15 expanding the heat dissipation area. At the same time, the cooling fan 17 blows external cold air into the gateway housing 2. The airflow first passes through the dustproof plate 13, which intercepts dust in the air. Then, the direct airflow is directed to the left and right sides by the diverter plate 16, so that the cold air evenly covers the gateway body 5 and heat dissipation components, achieving uniform heat dissipation. The hot air is discharged through the ventilation holes on the gateway housing 2. The dustproof plate 3 can block dust from entering through the ventilation holes. Both the dustproof plate 3 and the dustproof plate 13 are slidable and detachable structures, which are convenient for regular cleaning or replacement, and avoid dust accumulation and blockage that affects heat dissipation efficiency.

[0030] During installation, the connecting block 6 fixed at the bottom of the gateway housing 2 slides along the slide rail 7. The clamping plates 18 on both sides will self-adaptively limit the movement. The rubber pad 22 on the clamping plate 18, together with the rubber pad 19, squeezes the telescopic rod 20 and the spring 21 in the middle. The rebound force of the spring 21, together with the slide rail 7, completes the initial fixation. Then, the screw 8 is rotated around the connecting rod 11 on the fixing block 12 as the center, so that it slides into the groove of the fixing block 10 fixed on the gateway housing 2. Then, the nut 9 is tightened to lock the nut 9 with the fixing block 10, realizing the secondary limit. The fixing blocks 10 are provided on all four sides of the gateway housing 2, which can prevent the device from falling and being damaged due to contact. The anti-slip pad under the connecting seat 1 further enhances the overall stability and prevents the device from sliding and shifting.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
