[0022] At present, for some smart outdoor cabinet products, antennas are usually installed on the top of the cabinet. However, the antenna and the cabinet are generally fixed with screws, plastic clips, or by setting a bracket on the top of the cabinet. These traditional fixing methods are relatively complicated, seriously affecting the efficiency of installing the antenna in the cabinet and increasing the production cost.

[0023] Based on this, an embodiment of the present invention provides an antenna for use in a cabinet, which not only simplifies the installation process but also makes the antenna performance more stable and reduces the production cost.

[0024] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings.

[0025] Reference Figure 1 、 Figure 2The present invention provides an antenna for a cabinet, comprising: an outer shell 100, a PCB board 210, a coaxial cable 300, an iron sheet 400, and a cover 700; the outer shell 100 includes an outer cover 110 and a bottom shell 120, a chamber is formed between the outer cover 110 and the bottom shell 120, and a groove 121 is provided at the center of the bottom shell 120; the PCB board 210 is arranged in the chamber, a first LTE board 220 is provided on a first side of the PCB board 210, a second LTE board 230 is provided on a second side of the PCB board 210, and a WiFi board 240 is provided on a third side of the PCB board 210; one end of the coaxial cable 300 is connected to the PCB board 210, and the other end of the coaxial cable 300 is connected to a control unit 600 located in the cabinet 1000; the iron sheet 400 is provided in the groove 121 in the bottom shell 120, and a magnet 500 is provided below the iron sheet 400; the cover 700 is provided at the opening of the groove 121.

[0026] According to an antenna applied to a cabinet provided by an embodiment of the present invention, a first LTE antenna in the first LTE board 220, a second LTE antenna in the second LTE board 230, and a WiFi antenna on the WiFi board 240 are respectively connected to a control unit 600 inside the cabinet 1000 through a coaxial cable 300, thereby realizing the wireless communication requirements of the 4G or 2G communication networking and WiFi wireless connection of the control unit 600; an iron sheet 400 is provided in a groove 121 in the bottom shell 120, and a magnet 500 is provided under the iron sheet 400, and the antenna is fixed above the cabinet 1000 by the adsorption effect of the magnet 500. Compared with the solution of adopting a traditional fixing method or making the bottom shell 120 entirely of metal material and The solution of arranging a magnet 500 under the bottom shell 120 or the solution of making the bottom shell 120 into a non-metallic material and placing the magnet 500 inside the bottom shell 120 not only saves production costs and improves the magnetic attraction, but also reduces the weight of the antenna and speeds up the installation efficiency; in addition, a cover 700 is provided at the opening of the groove 121 in which the iron sheet 400 and the magnet 500 are built, which can effectively prevent external moisture from entering the interior of the groove 121, thereby protecting the iron sheet 400 and the magnet 500 from moisture erosion, keeping the magnetic force between the iron sheet 400 and the magnet 500 stable, and the antenna can be more stably fixed above the cabinet 1000, thereby improving the stability of the connection between the antenna and the control unit 600 in the cabinet 1000, thereby making the antenna performance more stable.

[0027] Preferably, the cover 700 may be a waterproof sticker or a waterproof coating, which can effectively prevent external moisture, dust and other debris from entering the groove 121, thereby avoiding affecting the stability of the internal components of the antenna.

[0028] It should be noted that the WiFi board 240 is located on the third side of the PCB board 210, which is closer to the first side of the PCB board 210. Connecting one end of the coaxial cable 300 to the first side of the PCB board 210 results in less loss and interference, and a stronger signal.

[0029] In some embodiments, the opening of the groove 121 is flush with the lower surface of the bottom shell 120, the magnet 500 is placed in the groove 121 and connected to the iron sheet 400, and a cover 700 is provided at the opening. The magnet 500 is only separated by a thinner cover 700. Compared with the solution in which the magnet 500 is magnetically attracted to the cabinet 1000 through the lower surface of the bottom shell 120, the magnetic attraction effect is stronger, and the antenna can be fixed on the cabinet 1000 more stably.

[0030] In some embodiments, a waterproof adhesive strip 130 is further included, and the waterproof adhesive strip 130 is disposed in the contact area between the outer cover 110 and the bottom shell 120 .

[0031] It is understandable that by providing a waterproof rubber strip 130 in the contact area, external moisture can be effectively blocked from entering the interior of the device, thereby protecting the internal circuit from moisture erosion, extending the service life of the antenna and ensuring stable operation of the antenna.

[0032] In some embodiments, the bottom housing 120 is fixedly connected to the outer cover 110 by a plurality of screws 800 .

[0033] Preferably, the bottom shell 120 is fixedly connected to the outer cover 110 by 8 screws 800. The tight connection between the bottom shell 120 and the outer cover 110 can protect the circuit board and the like inside the device from interference and damage from the external environment.

[0034] In some embodiments, a rubber sleeve 310 is provided at one end of the coaxial cable 300 , and the one end of the coaxial cable 300 is interference fit with the rubber sleeve 310 .

[0035] It can be understood that the rubber sleeve 310 can be tightly wrapped around the outside of the coaxial cable 300, effectively preventing the coaxial cable 300 from being subjected to external mechanical damage during use, such as scratches, wear, etc., and can also play a certain buffering role, reducing the degree of force on the coaxial cable 300 when it is impacted or squeezed, thereby protecting the integrity and performance of the coaxial cable 300, and further improving the stability of the connection between the antenna and the control unit 600 in the cabinet.

[0036] In some embodiments, a notch 111 is provided in the side of the outer cover 110 . The notch 111 cooperates with the coaxial cable 300 . The coaxial cable 300 passes through the notch 111 and is connected to the control unit 600 in the cabinet 1000 .

[0037] In some embodiments, the iron sheet 400 and the bottom shell 120 are integrally formed.

[0038] It should be noted that the outer cover 110 and the bottom shell 120 in the outer shell 100 both use plastic as their main structural material. The iron sheet 400 and the bottom shell 120 are integrated into one piece by injection molding, which simplifies the assembly process. At the same time, the iron sheet 400 can be more firmly installed in the bottom shell 120, thereby improving production efficiency.

[0039] In some embodiments, the outer cover 110 and the bottom shell 120 are both made of PC anti-ultraviolet material.

[0040] It can be understood that since the outer cover 110 and the bottom shell 120 are both made of PC anti-ultraviolet material, the antenna can withstand various harsh conditions in the outdoor environment for a long time, such as high temperature, sunshine, rain, etc. In addition, compared with the solution made of metal materials, it can also significantly reduce weight, facilitate carrying and transportation, and save production and handling costs.

[0041] In some embodiments, the thickness of the iron sheet 400 is 1-2 mm.

[0042] Preferably, the thickness of the iron sheet 400 is 1.5 mm.

[0043] It should be noted that the thickness of the iron sheet 400 is thicker than the sheet metal material of the cabinet 1000 shell, about 0.3 mm thick, which makes the adsorption effect between the iron sheet 400 and the magnet 500 stronger, preventing the magnet 500 from falling off and affecting the stability of the connection between the antenna and the control unit 600.

[0044] In some embodiments, a zinc coating is provided on the surface of the iron sheet 400 .

[0045] It is understandable that a galvanized layer is provided on the surface of the iron sheet 400, which can isolate the iron sheet 400 from direct contact with the air, prevent the iron sheet 400 from chemically reacting with oxygen and moisture in the air, thereby avoiding oxidation and rusting of the iron sheet 400, and avoiding affecting the adsorption effect of the iron sheet 400 and the magnet 500.

[0046] In some embodiments, the PCB board 210 is fixed to the bottom case 120 by a plurality of screws 800 .

[0047] Preferably, the PCB board 210 is fixed to the bottom case 120 by two screws 800.

[0048] It can be understood that fixing the PCB board 210 on the bottom shell 120 can ensure the stability of the PCB board 210 on the bottom shell 120, help prevent the PCB board 210 from being displaced or deformed when subjected to external force, and thereby ensure that the first LTE board 220, the second LTE board 230 and the WiFi board 240 arranged on different sides of the PCB board 210 are not damaged or displaced, which helps to stabilize the operation of the antenna.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.

[0050] Obviously, the embodiments described above are only some of the embodiments of the present application, rather than all of the embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the scope of protection of the present application. The present application can be implemented in many different forms.
