[0022] Example

[0023] See also Figures 1-3 , the utility model provides a technical solution:

[0024] The utility model provides an antenna arrangement structure of a learning machine, including a shell, in which a special-shaped mainboard 3, a cellular antenna, a WIFI antenna, a Bluetooth antenna and a positioning antenna are arranged, the WIFI antenna, the Bluetooth antenna and the positioning antenna are located on the shell corresponding to the upper side of the special-shaped mainboard 3, the cellular antenna includes a 4G / 5G main antenna 6 and a 4G / 5G diversity antenna 5, the 4G / 5G main antenna 6 is located on the shell corresponding to the lower side of the special-shaped mainboard 3, and the 4G / 5G diversity antenna 5 is located on the shell corresponding to the middle part of the special-shaped mainboard 3.

[0025] The present application installs a special-shaped motherboard 3 in the shell of the learning machine to take into account the arrangement of the antenna and the signal effect of the antenna when the internal space of the learning machine is limited and there are many parts. In order to enrich the functions of the learning machine, a positioning antenna is provided for positioning. In some specific embodiments, the positioning antenna includes a GPS antenna and a BD antenna. A cellular antenna that can be used for communication through a cellular network is also provided, so that the learning machine can be used to make calls and perform data communication without relying on external WiFi or Bluetooth, thereby expanding the scope of use of the learning machine.

[0026] Furthermore, the WIFI antenna, the Bluetooth antenna and the positioning antenna are a three-in-one composite antenna 4 .

[0027] To further reduce the antenna space, in this application, the WIFI antenna, Bluetooth antenna, and positioning antenna are designed as a three-in-one composite antenna 4, effectively saving space without affecting the respective effects of the above several antennas.

[0028] Specifically, the housing includes an upper housing 1 and a lower housing 2. The special-shaped main board 3 is arranged on the upper housing 1. It is L-shaped and includes a vertical board 301 and a horizontal board 302. The vertical board 301 is located on one side of the horizontal board 302.

[0029] In this application, considering the position requirements for antenna installation and the internal space stacking design of the learning machine, the L-shaped special-shaped main board 3 is adopted. Its vertical board 301 is located on the side above the horizontal board 302. The vertical board 301 can support the connection of the antenna that needs to be located at the top of the device, and the horizontal board 302 is used to support the main electrical components in the device, such as the main control chip, and the antenna that needs to be set on the lower side of the device.

[0030] Further, a first elastic sheet 7 connected to the three-in-one composite antenna 4 is provided on the upper side of the vertical board 301, a second elastic sheet 8 connected to the 4G / 5G diversity antenna 5 is provided in the middle part of the vertical board 301, and a third elastic sheet 9 connected to the 4G / 5G main antenna 6 is provided at the lower right side of the horizontal board 302.

[0031] The isolation degree between the 4G / 5G main antenna 6 and the 4G / 5G diversity antenna 5 is less than or equal to -15 dB.

[0032] In the cellular antenna module, the main antenna can effectively enhance the signal coverage range and transmission rate, improving the stability and performance of wireless communication. The diversity antenna processes and optimizes the signal based on the main antenna, further enhancing the signal quality and stability, reducing signal interference and packet loss rate, enabling users to conduct wireless communication more smoothly.

[0033] By setting the isolation degree between the main antenna and the diversity antenna, the coverage range and signal quality of the 4G / 5G network are guaranteed.

[0034] The 4G / 5G main antenna 6 and the 4G / 5G diversity antenna 5 respectively include a medium-high frequency antenna and a low-frequency antenna.

[0035] The three-in-one composite antenna 4, the 4G / 5G main antenna 6, and the 4G / 5G diversity antenna 5 are FPC antennas. The nickel plating thickness of the conductive contact of the FPC antenna is 2 - 7 μm, and the gold plating thickness is greater than or equal to 0.03 μm.

[0036] In this application, by adopting FPC antennas, the antenna occupied space is reduced. By setting the thickness of the conductive contact of the antenna, the effective contact between the FPC antenna and the elastic sheet is guaranteed.

[0037] The area of the lower housing 2 where the antenna is attached is optimized and flattened. The triple-composite antenna 4 is attached to the side of the upper part of the lower housing 2, the 4G / 5G main antenna 6 is attached to the side of the lower part of the lower housing 2, and the 4G / 5G diversity antenna 5 is attached to the side of the middle part of the lower housing 2.

[0038] By optimizing and flattening the area of the lower housing 2 where the antenna is attached, it is ensured that the FPC antenna is flatly adhered and connected to the housing. The triple-composite antenna 4 is attached to the upper part of the lower housing 2 to avoid handheld blocking of the antenna signal.

[0039] The main control chip 11 is provided on the cross plate 302, and the second elastic sheet 8 is connected to the diversity antenna PIN foot of the main control chip 11 through the IPX4 antenna socket 10 and the coaxial cable.

[0040] To adapt to the shape of the special-shaped main board 3 and meet the distance between the main antenna and the diversity antenna, the distance between the second elastic sheet 8 corresponding to the 4G / 5G diversity antenna 5 on the special-shaped main board 3 and the diversity antenna PIN foot of the main control chip 11 is relatively far, and it is inconvenient to route on the main board. This problem is solved by respectively arranging the IPX4 antenna socket 10 beside the second elastic sheet 8 and the diversity antenna PIN foot of the main control chip 11 and using the coaxial cable for connection.
