[0002] The IoT secure access router is a device between the perception layer and the network layer of the IoT. It has functions such as terminal identification, authentication and access control, behavior benchmark establishment, control and centralized management, and can solve security problems such as access control, intrusion control, and IP management. With the rise and rapid development of the IoT industry, the number of IoT network access devices has gradually increased. The significance of the IoT lies in that the devices are always in a controlled and communication state within the network. Therefore, the router often needs to be in operation for a long time or even continuously. The internal circuit boards and electronic components will continuously emit and accumulate high heat. If the heat cannot be dissipated and cooled in time, it will affect the performance of the device and the service life of the components. The existing heat dissipation of IoT access routers mainly relies on the air-cooling heat dissipation method of directly blowing with a heat dissipation fan integrally installed on the router body. Not only is the heat dissipation effect average, but it also easily causes the resonance of the machine shell, generates noise and loosens the components assembled by patch or connected by plugging. Moreover, the increase in IoT devices will lead to dense and messy wiring. In this working condition, it is also easy to cause virtual connection at the interface end, resulting in safety hazards such as poor data transmission and overheating of the interface. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the poor heat dissipation effect of the existing IoT access router with an integrated heat dissipation fan, as well as the application defects and safety hazards in the interface area, and provide an IoT secure access router. By adding a heat dissipation frame, it realizes the overall cold flow heat dissipation of each position of the router main body. Through methods such as hoisting, shock absorption, and external placement of the fan, it reduces the vibration of the main body, reduces noise and vibration, adds a wire fixing mechanism to fix the wires near the interface, making the wiring regular and clear while playing a role in preventing retraction, and preventing virtual connection caused by the loosening of the joint and the interface.

[0004] This IoT secure access router includes a router main body and a heat dissipation frame. The router main body is hoisted inside the heat dissipation frame, and there are gaps between the upper, lower, left, right, and rear sides of the router main body and the inner wall of the heat dissipation frame. Among them, the heat dissipation frame is a hollow shell that is open at the front side and is provided with a wire fixing mechanism at the lower edge, and the rear side is arc-shaped. Fan groups are installed on both sides of the front side of the heat dissipation frame. Slots are opened on the arc-shaped back plate at the rear side of the heat dissipation frame, and a semiconductor refrigeration sheet is embedded in the slots. The fan group includes a pair of speed-regulating fans, and the speed-regulating fans blow from both sides of the heat dissipation frame towards the arc-shaped back plate at the rear side of the heat dissipation frame. The wire fixing mechanism includes a lower clamping plate integrally formed at the lower edge of the front side of the heat dissipation frame and an upper clamping plate detachably fixed to the lower clamping plate by bolts. Semi-circular wire clamping grooves are arranged on the upper clamping plate and the lower clamping plate.

[0005] Furthermore, four suspension rod mechanisms are installed through the four corners of the top plate of the heat dissipation frame. Each suspension rod mechanism includes a suspension rod with a threaded part in the center, an adjusting nut, and a bearing platform. The bearing platform is fixed to the bottom of the suspension rod, and the adjusting nut is screwed onto the threaded part of the suspension rod above the heat dissipation frame.

[0024] The following uses specific embodiments to further describe the technical solutions of the present utility model, but the protection scope of the present utility model is not limited to the following embodiments.

[0025] Embodiment 1: As Figures 1 to 5As shown in the figure, this Internet of Things security access router includes a router main body 1 and a heat dissipation rack 2. The router main body 1 is hoisted inside the heat dissipation rack 2, and there are gaps between the upper, lower, left, right, and rear sides of the router main body 1 and the inner wall of the heat dissipation rack 2. Among them, the heat dissipation rack 2 is a hollow shell that is open at the front side and is provided with a wire fixing mechanism 3 at the lower edge and has an arc-shaped rear side; on both sides of the front side of the heat dissipation rack 2, a fan group 21 is installed. The arc-shaped back plate 201 of the rear side of the heat dissipation rack 2 is grooved, and a semiconductor refrigeration sheet 22 is embedded in the groove. The fan group 21 includes a pair of speed-regulating fans 211, and the speed-regulating fans 211 blow from both sides of the heat dissipation rack 2 towards the arc-shaped back plate 201 of the rear side of the heat dissipation rack 2; the wire fixing mechanism 3 includes a lower clamping plate 31 integrally formed at the lower edge of the front side of the heat dissipation rack 2 and an upper clamping plate 32 detachably fixed to the lower clamping plate 31 by bolts 33. The upper clamping plate 32 and the lower clamping plate 31 are provided with matching semicircular wire clamping grooves 34.

[0026] Embodiment 2: At the four corners of the top plate of the heat dissipation rack 2 of this Internet of Things security access router, four hanging rod mechanisms 4 are installed. The hanging rod mechanism 4 includes a hanging rod 41 with a threaded part 411 in the center, an adjusting nut 42, and a bearing platform 43. The bearing platform 43 is fixed at the bottom of the hanging rod 41, and the adjusting nut 42 is screwed onto the threaded part on the hanging rod 41 above the heat dissipation rack 2. The hanging rod mechanism is used to hoist the router main body. Among them, the four bearing platforms are used to support the lower part of the router main body, and the adjusting nut is used to adjust the height of each bearing platform, so as to realize the horizontal hoisting of the router main body and the gap adjustment between the upper and lower surfaces of the router main body and the upper and lower inner walls of the heat dissipation rack. The rest of the structures and components are as described in Embodiment 1 and will not be repeated.

[0027] Embodiment 4: A cushion 431 made of polyurethane soft material is provided on the bearing platform 43 of this Internet of Things security access router. The polyurethane soft material has a certain memory deformation function, which can compensate for small-angle deviations between the bottom surface of the router main body and the surface of the bearing platform during the adjustment of the hanging rod. At the same time, it has a shock-absorbing effect and can isolate the low-frequency vibration generated during the operation of the fan and the refrigeration sheet from being transmitted to the router main body. The rest of the structures and components are as described in Embodiment 1 and will not be repeated.

[0028] Embodiment 4: As Figure 6As shown in the figure, the IoT security access router further includes a controller 5. The controller includes a main control single-chip microcomputer 51, a relay module 52, and a power conversion module 53. The main control single-chip microcomputer 51 is connected to the fan group 21 and the semiconductor refrigeration sheet 22 through the relay module 52. The power conversion module 53 supplies power to the fan group 21 and the semiconductor refrigeration sheet 22 respectively. The signal input end of the main control single-chip microcomputer is connected to the temperature sensor inside the router body. The power conversion module converts, steps down, and stabilizes the external power supply and then supplies power to the fan group and the semiconductor refrigeration sheet respectively. The controller drives the motors of the fan group and the semiconductor refrigeration sheet to operate by controlling the corresponding relays on the relay module. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0029] During operation: Place the cold surface of the semiconductor refrigeration sheet inside the heat dissipation frame housing and the hot surface outside the heat dissipation frame housing. When the controller receives a signal that the temperature sensor inside the router body is too high, it drives the semiconductor refrigeration sheet to operate, cooling the air behind the router body. If the temperature continues to rise, the controller drives one or two speed-regulating fans to operate and blow air, pressing out the cooled air behind the router body, so that the cold flow covers all sides of the entire main body of the machine. After the temperature drops, first turn off the speed-regulating fans in sequence, and then stop the operation of the semiconductor refrigeration sheet. The operation and stop sequence of the fans and the refrigeration sheet can be programmed and adjusted in the controller single-chip microcomputer according to the characteristics of the router. When adding equipment, open the upper clamping plate, select the WAN network group, then connect the equipment to the corresponding LAN network port on the network group of the router body through a network cable, buckle on the upper clamping plate, push the network cable near the interface inward for a certain distance, and snap it into the corresponding clamping grooves on the upper and lower clamping plates. Buckle on the upper clamping plate and tighten the bolts on both sides to complete the wiring.

[0030] This IoT security access router overcomes the poor heat dissipation effect of the existing IoT access router with an integrated cooling fan, as well as the application defects and security hazards in the interface area. By adding a heat dissipation frame, it realizes the overall cold flow heat dissipation of each position of the router body. Through methods such as hoisting, shock absorption, and external placement of the fan, it reduces the vibration of the main body, reduces noise and vibration, and adds a wire fixing mechanism to fix the wires near the interface, making the wiring regular and clear while playing a role in preventing retraction and preventing virtual connection caused by the loosening of the joint and the interface.
