Description

Technical Field

[0001] The utility model belongs to the technical field of positioning, and in particular relates to a housing structure of a hybrid positioning base station. Background Art

[0002] With the continuous acceleration of urbanization, the total area of ​​indoor space is increasing rapidly, and the large demand and application of location-based services have shifted from outdoor to indoor. However, for the complex indoor space environment, a single positioning source and technology is indeed difficult to achieve the same universality as GNSS in outdoor environment. Therefore, in order to achieve accurate positioning in indoor space, it is necessary to comprehensively consider multiple positioning technologies and sensor information, build a multi-source fusion positioning system, and expand the application scenarios; however, multiple sensors will interfere with each other, so it is impossible to achieve the ideal positioning accuracy. Utility Model Content

[0003] The utility model provides a hybrid positioning base station shell structure, which reasonably arranges the Bluetooth antenna and the sound-emitting element, thereby achieving the best positioning effect of "radio frequency + audio".

[0004] To solve the above problems, the technical solutions provided by the present invention are as follows:

[0005] The utility model provides a hybrid positioning base station housing structure, comprising a main body structure, with an antenna (2) and a power interface (4) respectively arranged on both sides of the main body structure; an upper shell (1) is arranged on the top of the main body structure, a speaker grille (3) is fixed to the top of the upper shell (1) by screws, and a lower shell (5) is arranged on the bottom of the main body structure, and the lower shell (5) is connected to the antenna (2) by an exposed SMA connector;

[0006] The lower shell (5) has symmetrically distributed mounting platforms (9) inside for attaching Bluetooth antennas, which not only maintains the distance between the Bluetooth antennas as much as possible and avoids mutual interference between the antennas, but also enables the antenna (2) to maintain a fixed posture, thereby achieving stable Bluetooth performance.

[0007] According to an optional embodiment of the utility model, the lower shell (5) fixes the power interface (4) via a wire pressing plate (8).

[0008] According to an optional embodiment of the utility model, the lower shell (5) refracts the indicator light of the circuit board in the main structure to its side through the light guide column (7), thereby ensuring the gathering of the indicator light through a shorter path.

[0009] According to an optional embodiment of the utility model, heat dissipation windows (10) are distributed on both sides of the lower shell (5), and the heat dissipation windows (10) adopt a shutter structure, which not only ensures the ventilation performance, but also ensures the dustproof and airtightness of the entire equipment.

[0010] According to an optional embodiment of the utility model, the lower shell (5) is mounted on the ceiling or the universal bracket via fixing bolts (6).

[0011] Beneficial effect: The embodiment of the utility model provides a hybrid positioning base station shell structure, including an upper shell, an antenna, a power interface, a lower shell and fixing bolts. A speaker mesh cover is fixed by screws on the top of the upper shell. A certain distance is maintained between the speaker mesh cover and the speaker to form a sound cavity, which can maximize the sound performance of the speaker; symmetrically distributed installation platforms are arranged inside the lower shell for pasting Bluetooth antennas, which not only maintains the distance between Bluetooth antennas as much as possible and avoids mutual interference between antennas, but also enables the antenna to maintain a fixed posture, thereby achieving stable Bluetooth performance.

[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the embodiment of the utility model provides a hybrid positioning base station shell structure, including a main structure, and antennas 2 and power interfaces 4 are respectively arranged on both sides of the main structure. An upper shell 1 is arranged on the top of the main structure, and a speaker grille 3 is fixed to the top of the upper shell 1 by screws. By selecting a suitable mesh grille aperture size, the dustproof performance of the equipment is guaranteed, so that the speaker can sound normally, and foreign objects will not contact the speaker generating surface to cause malfunctions; at the same time, the distance between the speaker grille 3 and the speaker is tested to form a sound cavity, which can guarantee the sound performance of the speaker to the greatest extent.

[0018] A lower shell 5 is provided at the bottom of the main structure, and the lower shell 5 is connected to the antenna 2 through an exposed SMA connector. It is not only easy to disassemble, but also the universal interface size can adapt to a variety of antennas. During use, the antenna specifications can be replaced according to actual needs.

[0019] The lower shell 5 fixes the power interface 4 through the wire pressing plate 8, so that the power interface 4 is not easy to fall off. The lower shell 5 refracts the indicator light of the circuit board in the main structure to its side through the light guide column 7, ensuring the gathering of the indicator light with a shorter path. The lower shell 5 is symmetrically distributed with mounting platforms 9 for pasting Bluetooth antennas, which not only maintains the distance between Bluetooth antennas as much as possible and avoids mutual interference between antennas, but also enables the antenna 2 to maintain a fixed posture, thereby achieving stable Bluetooth performance. There are heat dissipation windows 10 distributed on both sides of the lower shell 5. The heat dissipation windows 10 adopt a shutter-type structure, which not only ensures the ventilation performance, but also ensures the dust-proof and airtightness of the entire device.

[0020] The lower shell 5 is mounted on the ceiling or the universal bracket through the fixing bolts 6. It is only necessary to determine the screw hole size of the base, and the base and the product can be easily disassembled and separated during the actual construction process.

[0021] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention.
