Description

Technical Field

[0001] This utility model relates to the field of antenna box technology, specifically to an outdoor antenna box. Background Technology

[0002] Outdoor antenna boxes are a crucial barrier ensuring the stable operation of wireless communication equipment (such as antennas and signal processing units) in harsh outdoor environments, including exposure to sun, rain, and drastic temperature changes. The core of their protective performance lies in the long-term reliable sealing of the interface between the upper shell and the base, preventing moisture, humidity, and dust from intruding and causing internal circuit failure. Currently, these products commonly use sealing rings (such as O-rings) as the primary sealing element at the connection points.

[0003] However, existing outdoor antenna boxes typically place the sealing ring simply into a pre-designed open groove in the base or upper shell. During the assembly process, especially for large or irregularly shaped antenna boxes, the sealing ring lacks effective radial restraint and pre-fixation. It is highly susceptible to displacement, twisting, or even partial detachment from the groove due to improper operation or gravity. This directly leads to uneven compression of the sealing ring, with some areas experiencing overpressure and others insufficient pressure, creating leakage channels. Furthermore, even if the initial installation is correct, the sealing ring can easily shift unexpectedly due to a lack of restraint during subsequent transportation, installation (such as vibrations during hoisting or tightening screws), or maintenance opening and closing, thus compromising the initial seal.

[0004] In view of this, this application proposes an outdoor antenna box to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an outdoor antenna box that can effectively prevent the sealing ring from shifting or twisting during installation, transportation and use, ensure uniform compression of the sealing ring, and improve sealing performance.

[0029] This embodiment relates to an outdoor antenna box, see reference. Figures 1-4 The antenna box body 100 includes a bottom shell 10, a front shell 20 fastened to the bottom shell 10, and a sealing ring 30 disposed between the bottom shell 10 and the front shell 20. The bottom shell 10 is provided with a sealing groove 11 for accommodating the sealing ring 30.

[0030] The bottom shell 10 is provided with a plurality of positioning blocks 12, which are evenly distributed along the circumferential direction of the bottom shell 10. The sealing ring 30 is provided with a corresponding positioning ring 31 for engaging with the positioning blocks 12.

[0031] In this embodiment, both the sealing groove 11 and the sealing ring 30 are square, and there are eight positioning blocks 12 and eight positioning rings 31. In other embodiments, the sealing groove 11 and the sealing ring 30 can also be circular or other shapes, and the number of positioning blocks 12 and positioning rings 31 can be increased or decreased according to the actual situation, which is not limited here.

[0032] The bottom shell 10 and the front shell 20 are sealed together by a sealing ring 30, effectively preventing rainwater, dust, and other external impurities from entering the antenna box, thus ensuring the normal operation of the electronic components inside the antenna box. Simultaneously, the snap-fit ​​engagement of the positioning block 12 and the positioning ring 31 enables the positioning and fixation of the sealing ring 30, simplifying the antenna box assembly process and improving its sealing performance. This effectively prevents the sealing ring 30 from shifting or twisting during installation, transportation, and use, ensuring uniform compression of the sealing ring 30 and further improving sealing performance.

[0033] Furthermore, the bottom shell 10 is provided with an abutment platform 13 for abutting against the front shell 20. The sealing groove 11 and the positioning block 12 are both located on the abutment platform 13, and the positioning block 12 is located on the side of the sealing groove 11 closer to the inside of the bottom shell 10.

[0034] The abutment platform 13 allows for a tighter fit between the bottom shell 10 and the front shell 20 during assembly, further enhancing the sealing effect of the antenna box. The sealing groove 11 and the positioning block 12 are both located on the abutment platform 13, resulting in a more compact overall structure. Furthermore, placing the positioning block 12 on the side of the sealing groove 11 closer to the inside of the bottom shell 10 effectively prevents misalignment of the sealing ring 30 during installation, thus ensuring accurate installation of the sealing ring 30.

[0035] Furthermore, the size of the positioning ring 31 is adapted to the positioning block 12, the positioning ring 31 is sleeved on the outside of the positioning block 12, and the abutment platform 13 is provided with a relief groove 131 for accommodating the positioning ring 31.

[0036] When installing the sealing ring 30, first align the positioning ring 31 on the sealing ring 30 with the positioning block 12 on the bottom shell 10. Then, place the sealing ring 30 in the sealing groove 11 and engage the positioning ring 31 with the positioning block 12. At this time, part of the positioning ring 31 is located in the relief groove 131 and part is located above the abutment platform 13. The relief groove 131 on the abutment platform 13 provides a certain amount of movement space for the positioning ring 31, facilitating the engagement between the positioning ring 31 and the positioning block 12. At this time, the top surface of the positioning ring 31 is located below the top surface of the positioning block 12. In addition, the positioning ring 31 can also further limit the sealing ring 30, preventing the sealing ring 30 from twisting or shifting during installation or use, thereby ensuring the sealing effect of the sealing ring 30.

[0037] Furthermore, the faceplate 20 is fastened to the edge of the abutment platform 13, that is, the abutment platform 13 is housed inside the faceplate 20, and the faceplate 20 is provided with an abutment protrusion 21 for abutting the top of the sealing ring 30 at the position corresponding to the sealing groove 11.

[0038] Understandably, the abutment flange 21 effectively presses against the top surface of the sealing ring 30, further enhancing the sealing effect. When the faceplate 20 is fastened to the edge of the abutment platform 13, the abutment flange 21 is in close contact with the top of the sealing ring 30, forming a sealed boundary. At the same time, rainwater from the outside will fall vertically along the outer periphery of the faceplate 20, effectively preventing water, dust, and other external impurities from entering the antenna box and protecting the electronic components inside the antenna box from damage.

[0039] Furthermore, a plurality of reinforcing ribs 22 are evenly provided between the abutting protrusion 21 and the edge of the shell 20.

[0040] The reinforcing ribs 22 enhance the overall strength of the housing 20 and improve the pressing effect of the abutment flange 21 on the sealing ring 30, further ensuring sealing performance. Furthermore, the reinforcing ribs 22 also disperse stress, preventing deformation of the housing 20 due to external impact or long-term use, thereby extending the service life of the antenna box.

[0041] Furthermore, the abutment platform 13 has a plurality of first positioning posts 132 distributed circumferentially. The face shell 20 is provided with a second positioning post 23 corresponding to the position of the first positioning post 132, which is inserted and engaged with the first positioning post 132. The second positioning post 23 is located between the outer peripheral edge of the face shell 20 and the abutment protrusion 21. The first positioning post 132 is provided with a insertion hole for the second positioning post 23 to be inserted, and the second positioning post 23 is provided with an internal thread for engaging with a screw.

[0042] Understandably, the precise positioning and stable connection between the front shell 20 and the abutment platform 13 are achieved through the insertion and engagement of the first positioning post 132 and the second positioning post 23. This ensures a stable connection between the front shell 20 and the bottom shell 10, simplifies the assembly process, improves assembly efficiency, and effectively prevents relative displacement between the front shell 20 and the abutment platform 13, further enhancing the overall structural stability of the antenna box. Simultaneously, the internal thread design on the second positioning post 23 allows screws to easily pass through the front shell 20 and be tightly secured to the first positioning post 132, further strengthening the connection between the front shell 20 and the abutment platform 13 and ensuring the reliability and durability of the antenna box in harsh outdoor environments.

[0043] Furthermore, the bottom shell 10 is made of aluminum, and the top shell 20 is made of plastic.

[0044] The aluminum base shell 10 offers excellent heat dissipation and corrosion resistance, effectively withstanding varying outdoor weather conditions and ensuring the normal operation of the internal electronic components of the antenna box. The plastic front shell 20, on the other hand, is lightweight, low-cost, and easy to process and mold, meeting the diverse design requirements of antenna boxes and the convenience of user operation. Compared to traditional metal base shells 10 and 20, it effectively avoids the shielding of antenna signals by metal, and compared to all-plastic base shells 10 and 20, its heat dissipation and corrosion resistance are significantly improved.

[0045] Furthermore, the surface of the faceplate 20 is provided with a metal spray coating 201.

[0046] The metal spray coating 201 gives the surface of the faceplate 20 a metallic luster, which on the one hand improves the decoration of the antenna box body 100 and makes it more beautiful, and on the other hand improves the corrosion resistance of the faceplate 20, further extending the service life of the antenna box body 100.

[0047] Furthermore, the antenna box body 100 also includes a circuit board 40 disposed inside the bottom shell 10 and the front shell 20, a heat sink assembly 50 disposed on the circuit board 40, and a plurality of antenna bodies 60 disposed on the outside of the bottom shell 10 and electrically connected to the circuit board 40. The circuit board 40 integrates a signal receiving module, a signal processing module and a power management module. The heat sink assembly 50 is used to dissipate heat from the circuit board 40, and the antenna bodies 60 are used to receive and transmit wireless signals.

[0048] It should be noted that the signal receiving module, signal processing module, and power management module integrated on circuit board 40 together constitute the signal processing system of the antenna box. The signal receiving module is responsible for receiving wireless signals from the outside and converting them into electrical signals; the signal processing module decodes and amplifies the received electrical signals to ensure the clarity and accuracy of the signal; and the power management module is responsible for providing a stable and reliable power supply to the entire system to ensure that the antenna box can continue to work normally.

[0049] As an important component for heat dissipation of the circuit board 40, the heat sink assembly 50 can quickly concentrate the heat generated by the circuit board 40 and dissipate it through the base when the circuit board 40 is working and generating heat. This ensures that the operating temperature of the circuit board 40 is always kept within a safe range, thereby extending the service life of the circuit board 40 and improving the overall performance of the antenna box.

[0050] Furthermore, the bottom shell 10 is also equipped with an HDMI interface 14, an RJ45 network interface 15, a power input interface 16, and a USB interface 17 that are electrically connected to the circuit board 40.

[0051] The HDMI port 14, RJ45 network port 15, power input port 16, and USB port 17 are all standard technologies in this field and will not be described in detail here. It should be noted that, to ensure airtightness, sealing connectors 18 are provided at the HDMI port 14, RJ45 network port 15, power input port 16, and USB port 17.

[0052] Working principle: During assembly, the positioning block 12 and the positioning ring 31 cooperate to quickly position and securely fix the sealing ring 30, stably fixing the sealing ring 30 in the sealing groove 11. At the same time, the abutting flange 21 presses against the top of the sealing ring 30, further enhancing the sealing effect of the sealing ring 30. This makes the sealing ring 30 less prone to displacement or twisting during installation, transportation and use, ensuring uniform compression of the sealing ring 30, thereby improving the sealing performance.

[0053] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
