Description

Technical Field

[0001] The utility model belongs to the technical field of wireless communication, and in particular relates to a built-in structure of a mining machine chassis antenna. Background Art

[0002] With the development of information technology, more and more devices require access to communication networks. Device access to communication networks is generally divided into wired and wireless methods. Compared to wired communication, wireless communication, with its convenience and flexibility, is playing an increasingly important role. The wireless communication range of traditional mining machine chassis is relatively short, generally ranging from tens to hundreds of meters. This is mainly due to the fact that traditional chassis generally use microstrip antennas or rod antennas, which have low gain and cannot radiate long distances.

[0003] In order to increase the wireless communication distance of the mining machine chassis, high-gain antennas, such as horn antennas, are usually used. However, horn antennas are large in size. If placed directly inside the chassis, they will take up a lot of internal space. If placed outside the chassis, it will cause many inconveniences. Utility Model Content

[0004] Based on this, in order to solve the above technical problems, a mining machine chassis antenna built-in structure is provided.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A built-in structure for a mining machine chassis antenna, characterized in that it includes a chassis body, a horn antenna and a chassis fan, the chassis body having a window adapted to the radiation cavity opening of the horn antenna, the horn antenna being arranged in the chassis body, and its radiation cavity opening being docked with the window, the radiation cavity wall of the horn antenna having an air outlet, the blades of the chassis fan being arranged in the radiation cavity opening, and the drive shaft thereof being parallel to the center line of the radiation cavity.

[0007] The utility model integrates the horn antenna and the chassis fan together, and the two are spatially multiplexed, which not only ensures the radiation performance of the horn antenna, but also ensures the heat dissipation capacity of the fan. It realizes that the horn antenna is built into the mining machine chassis without occupying too much internal space of the chassis, and improves the wireless communication distance of the mining machine.

[0010] Figure 2 The three-dimensional structure of the horn antenna of the embodiment of the utility model is shown in FIG. Figure 1 ;

[0011] Figure 3 The three-dimensional structure of the horn antenna of the embodiment of the utility model is shown in FIG. Figure 2 . DETAILED DESCRIPTION

[0012] The following will illustrate the implementation of the present utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the present utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the present utility model are also within the scope of protection of the present utility model.

[0013] like Figure 1 As shown, an embodiment of the present application provides a mining machine chassis antenna built-in structure, including a chassis body 110, a horn antenna 120 and a chassis fan 130.

[0014] The chassis body 110 has a window 111 adapted to the radiation cavity of the horn antenna 120 , wherein the window 111 is in the front-to-back direction and is located at the rear side of the chassis body 110 .

[0015] The horn antenna 120 adopts a broadband double-ridged horn antenna, which is arranged in the front and back directions inside the chassis body 110. The broadband double-ridged horn antenna has a high bandwidth and can operate at multiple frequencies. The high gain characteristics of the horn antenna can effectively improve the wireless communication distance of the device.

[0016] like Figure 2 As shown, the interior of the horn antenna 120 is a radiation cavity 121, the front side is a base 122, which is used to receive signals from the antenna feed port, the rear side is a radiation cavity opening 121a, and the left and right sides are integrally formed with air outlets 123 for ventilation of the chassis fan 130 (sending cold air inward or drawing hot air outward). The upper and lower sides serve as radiation surfaces for guiding the antenna energy radiation. At the same time, two symmetrical antenna ridges 121b are fixed on the inner surfaces of the two to widen the antenna bandwidth.

[0017] The radiation cavity opening 121a is connected to the window 111, and the connection is fixed by a plurality of screws.

[0018] It is understandable that the horn antenna 120 is not limited to a broadband double-ridged horn antenna, and the number, position and size of the air outlets 123 are not limited to the above definitions.

[0019] like Figure 2 and Figure 3 As shown, the chassis fan 130 includes blades 131 , a drive shaft 132 and a drive motor 133 .

[0020] The blade 131 is arranged in the radiation cavity opening 121 a and is flush with the end surface of the radiation cavity opening 121 a.

[0021] The blades 131 are made of plastic to reduce their impact on the horn antenna 120 .

[0022] The driving shaft 132 coincides with the center line of the radiation cavity 121 , its rear end is connected to the center of the blade 131 , and its front end passes forward through the base 122 of the horn antenna 120 and is connected to the driving motor 133 .

[0023] The driving motor 133 is fixed to the base 122 via a bracket (not shown).

[0024] The above structure reuses the space of the horn antenna 120 and the chassis fan 130, and the area occupied is smaller than the sum of the areas of the traditional horn antenna and chassis fan. Compared with the traditional method of separately built-in horn antenna, it reduces the internal space occupied by the chassis and improves the integration.

[0025] As can be seen from the above, the embodiment of the present application provides a built-in structure for the antenna of the mining machine chassis, which integrates the horn antenna and the chassis fan together, and the two are spatially multiplexed, which not only ensures the radiation performance of the horn antenna, but also ensures the heat dissipation capacity of the fan. It realizes the integration of the horn antenna into the mining machine chassis without occupying too much internal space of the chassis, and improves the wireless communication distance of the mining machine.

[0026] Obviously, those skilled in the art may make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include these modifications and variations.
