[0039] In the related art, the Internet of Things gateway usually uses a sealing ring for sealing or fills the inside of the box with glue to meet the waterproof index of the gateway. However, when using the sealing ring method, water leakage may occur at the connection, its waterproof level cannot meet the higher waterproof requirements, and the volume is relatively large; while the overall glue filling method is not conducive to the subsequent operation and maintenance of the gateway, and the glue filling process results in too high costs, and there is also a possibility that there are metal substances in the glue, thus affecting the antenna performance and the working stability of the electronic control components inside the gateway. In addition, in the related art, the antenna usually adopts an external connection design, and connectors such as SMA or IPEX are used to connect the antenna and the gateway. The above-mentioned external connection method of the antenna may have problems such as poor on-site manual installation and generate additional labor costs and material costs, with relatively high costs.

[0040] In view of this, the present embodiment provides a gateway device 100, aiming to seal by setting a first mating sealing structure between the first housing 11 and the second housing 12 and filling and sealing glue, and at the same time adopting the method of integrating the antenna 22 inside, so as to reduce costs, ensure the installation quality, and facilitate operation and maintenance, thereby solving the above technical problems.

[0041] As Figures 1 to 7 shown, according to an embodiment of the present invention, a gateway device 100 is proposed. The gateway device 100 includes a housing 1 and an electronic control component. Among them, a receiving space is formed inside the housing 1, and the electronic control component is arranged in the receiving space. The electronic control component includes a main control board 21 and an antenna 22, and the antenna 22 is assembled on the main control board 21. By integrating the antenna 22 inside the gateway device 100, the link of installing the antenna 22 additionally on-site is cancelled, without on-site installation costs and the quality is improved.

[0042] The housing 1 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are assembled together in an opposing manner to form the housing 1. The materials of the first housing 11 and the second housing 12 are plastic. The use of plastic for the housing 1 not only ensures the signal transmission ability but also avoids the problems that the external antenna 22 is prone to damage or reduced lifespan under external force and collision. Moreover, the plastic housing 1 also has the advantages of being lightweight and low-cost. The first housing 11 and the second housing 12 are hermetically connected through a first mating and sealing structure. The first mating and sealing structure includes a first sealing portion 31 provided on the peripheral edge of the first housing 11 and a first mating portion 32 provided on the peripheral edge of the second housing 12. A first sealing material is filled between the first sealing portion 31 and the first mating portion 32 to seal the housing 1. The first sealing material includes sealant, and the connection gap between the first housing 11 and the second housing 12 is filled with the sealant to play a sealing role. The first sealing material can also be sealant putty or a sealing ring. By filling the putty or press-fitting the sealing ring at the connection of the first housing 11 and the second housing 12, while ensuring the waterproof effect, it is convenient for subsequent maintenance. By filling sealant at the connection of the first housing 11 and the second housing 12, compared with the overall potting method in the related art, the potting volume is less than 3% of the total potting volume, reducing the amount of glue used and the potting cost, facilitating the operation and maintenance of the gateway device 100, and the components such as the antenna 22 and the main control board 21 do not come into contact with the sealant, which can improve the performance of the antenna 22 and the working stability and reliability of the main control board 21.

[0043] In some embodiments of the present invention, one of the first sealing portion 31 and the first mating portion 32 is set as a first sealing groove 311, and the other is set as a first sealing protrusion 321. In this embodiment, the first sealing groove 311 is provided on the peripheral edge of the first housing 11, and the first sealing protrusion 321 is provided on the peripheral edge of the second housing 12 and is adapted to the first sealing groove 311. During assembly, the sealant is applied in the first sealing groove 311, and then the second housing 12 is buckled onto the first housing 11, and after pressing for a period of time and waiting for the sealant to fasten and glue the first housing 11 and the second housing 12 together, through the outer-ring potting method, while reducing the potting cost, the sealing performance and waterproof performance of the housing 1 are ensured, and the sealant does not come into contact with the internal antenna 22 and the main control board 21 and other electronic control components, improving the performance and stability of the antenna 22 and the main control board 21.

[0044] In this embodiment, a limiting structure is further provided between the first housing 11 and the second housing 12. The limiting structure includes a limiting portion 51 and a limiting mating portion 52. Specifically, the limiting portion 51 includes a plurality of clamping blocks 511 provided on the first housing 11. The plurality of clamping blocks 511 are arranged at intervals on the inner peripheral wall of the first housing 11. The limiting mating portion 52 includes a plurality of clamping grooves 521 provided on the second housing 12. The plurality of clamping grooves 521 are arranged at intervals on the inner peripheral wall of the second housing 12. The plurality of clamping blocks 511 and the plurality of clamping grooves 521 are arranged in one-to-one correspondence. During assembly, sealant is filled in the first sealing groove 311, and then the clamping blocks 511 are connected in cooperation with the clamping grooves 521, so as to limit the assembly of the first housing 11 and the second housing 12, ensure the accuracy of the buckling of the first housing 11 and the second housing 12, and then press and fix to improve the fastening and reliability of the connection between the first housing 11 and the second housing 12.

[0045] In some embodiments of the present utility model, the electronic control assembly further includes a connection assembly 6. The connection assembly 6 includes a connection wire harness 61 and a connection plate 62. One end of the connection wire harness 61 is connected to the main control board 21, and the other end passes through the connection plate 62 and is connected to an external device. An opening 111 is provided on the first housing 11. The connection plate 62 is arranged at the opening 111. The connection plate 62 and the first housing 11 are hermetically connected through a second mating sealing structure. Specifically, the connection assembly further includes a connection terminal 63. The connection terminal 63 is welded to the main control board 21. The connection terminal 63 is equipped with an RS485 connection signal and power supply. The second mating sealing structure includes a second sealing portion 41 provided on the connection plate 62 and a second mating portion 42 provided on the first housing 11. One of the second sealing portion 41 and the second mating portion 42 is set as a second sealing groove 421, and the other is set as a second sealing protrusion 411. In this embodiment, the second sealing groove 421 is arranged along the peripheral edge of the opening 111 on the first housing 11. The second sealing protrusion 411 is arranged along the peripheral edge of the connection plate 62 on the connection plate 62 and is adapted to the second sealing groove 421. A second sealing material is filled between the second sealing groove 421 and the second sealing protrusion 411. The second sealing material includes sealant, and can also be sealant clay or a sealing ring. During the assembly of the connection assembly 6, the connection wire harness 61 is welded to the main control board 21, and then sealant is applied in the second sealing groove 421. Then, the connection plate 62 is buckled on the first housing 11, and after pressing for a period of time and waiting for the sealant to firmly bond the first housing 11 and the connection plate 62 together. By providing the connection plate 62 and arranging a second mating sealing structure between the connection plate 62 and the first housing 11, it is convenient for the connection arrangement of the connection wire harness 61 and the main control board 21, and at the same time, the overall sealing and waterproofness of the housing 1 are ensured.

[0046] In some embodiments of the present utility model, the first housing 11 extends in a direction towards the inner cavity of the first housing 11 to form a mounting portion 112. The opening 111 penetrates through the mounting portion 112. The second sealing groove 421 is disposed on the mounting portion 112 along the circumferential direction of the opening 111, and the second sealing protrusion 411 is disposed on the connecting plate 62 along the circumferential direction of the connecting plate 62. By providing the mounting portion 112 and arranging the second sealing groove 421 on the peripheral edge of the mounting portion 112, when the connecting plate 62 is assembled with the first housing 11, the outer peripheral wall of the connecting plate 62 abuts against the inner wall of the mounting portion 112, ensuring the stability and reliability of the installation of the connecting plate 62 and further improving the overall sealing performance of the housing 1.

[0047] In the related art, gateways basically adopt spring antennas 22 or horn antennas 22, etc. The spring antennas 22 or horn antennas 22 are relatively large in volume and high in cost.

[0048] In contrast, in some embodiments of the present utility model, the antenna 22 is a steel plate antenna 22, and the steel plate antenna 22 is welded to the main control board 21. By adopting the steel plate antenna 22, the steel sheet material has characteristics such as plasticity and transformable shape through special treatment, which can greatly reduce the volume of the antenna 22 and support more frequency bands at the same time.

[0049] In the related art, most gateways adopt the scheme of MCU + general module. Due to the setting of the MCU circuit, the volume and cost of the gateway device 100 increase, and the working current is also relatively large.

[0050] In contrast, in some embodiments of the present utility model, the electronic control component includes an OpenCPU module, and the OpenCPU module is disposed on the main control board 21. By providing the OpenCPU module, the MCU circuit is cancelled, and all code logics are written in the OpenCPU module. The OpenCPU module can integrate computing and communication, making the volume of the gateway device 100 smaller and reducing the volume, cost and working current of the gateway device 100.

[0051] In a second aspect of the present utility model, a heating, ventilation and air conditioning (HVAC) device is provided. The HVAC device includes an HVAC device body and the gateway device 100 as described above. The gateway device 100 is communicatively connected to the HVAC device body.

The first mating seal structure includes a first seal portion 31 and a first mating portion 32, and a sealant is provided between the first seal portion 31 and the first mating portion 32. The first housing 11 and the second housing 12 are hermetically connected by the sealant, achieving effective waterproof sealing of the outer shell 1, meeting the waterproof sealing performance requirements for outdoor installation. At the same time, only the sealant is filled at the connection between the first housing 11 and the second housing 12, reducing the costs of glue filling labor and materials, and facilitating the operation and maintenance of the gateway device 100.

[0052] In a third aspect of the present utility model, an elevator is provided. The elevator includes an elevator body and the gateway device 100 as described above. The gateway device 100 is communicatively connected to the elevator body.

[0053] As described above, the above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto.
