Description

Technical Field

[0001] This utility model relates to the technical field of automotive electronics, and in particular to a dual BT-WIFI structure for an in-vehicle host. Background Technology

[0002] With the continuous development of technology, the functions of in-vehicle host systems are becoming more and more abundant, including in-vehicle Bluetooth, in-vehicle WIFI, and in-vehicle mobile data. For more convenient operation, in-vehicle Bluetooth and in-vehicle WIFI are usually used to connect with the user's mobile phone for control.

[0003] Traditional in-vehicle head units have poor shielding, leading to unstable signal transmission. Furthermore, when in-vehicle Wi-Fi is installed on a head unit, the sheet metal bracket on the vehicle body, being the same size as the head unit itself, can interfere with and obstruct the antenna signal. This also reduces the sealing and protection provided between the sheet metal bracket and the entire head unit. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a dual BT-WIFI structure for a vehicle host, which uses a strategy of extending the PCBA sheet metal bracket inward to avoid interference and obstruction of the antenna signal by the sheet metal bracket, while retaining the sealing and EMC protection function of the sheet metal bracket for the entire machine space.

[0006] To achieve the above objectives, this utility model proposes a dual BT-WIFI structure for a vehicle-mounted host, comprising a metal frame, a sheet metal bracket, an inner groove, a plastic panel, BT-WIFI antennas, a circuit board, a sheet metal base, signal clearance holes, and fixing screws. The sheet metal bracket is mounted on the metal frame; the inner groove is formed on the sheet metal bracket; the plastic panel is detachably mounted on the metal frame; the circuit board is disposed within the metal frame; there are two sets of BT-WIFI antennas, each set being mounted on the circuit board; the sheet metal base is disposed on the bottom wall of the metal frame; the signal clearance holes are formed on the sheet metal base; and the fixing screws are threadedly connected to the sheet metal base, the circuit board, and the metal frame.

[0007] The dual BT-WIFI structure of the vehicle-mounted host of this utility model has the following advantages:

[0008] 1. This solution has two BT WIFI antennas installed on the PCBA.

[0009] 2. PCBA sheet metal brackets are used for front-end fixation of PCBA and shielding of the entire machine's EMC.

[0010] 3. This design avoids interference and obstruction of the antenna signal by extending the PCBA sheet metal bracket inward in the BT WIFI antenna area, while retaining the sealing and EMC protection function of the sheet metal bracket for the entire machine space.

[0011] 4. Moreover, this solution has a lower cost, effectively improves the overall strength, and reduces the weight of the whole machine.

[0012] 5. This solution utilizes an integrated design approach with plastic panels, enabling the panels to serve both aesthetic purposes and to block the antenna signal avoidance holes on the bottom shell, thereby reducing costs and assembly complexity.

[0013] In addition, the dual BT-WIFI structure of the vehicle host proposed in the above application may also have the following additional technical features:

[0014] Specifically, the plastic panel includes a fixed panel and a shielding structure, wherein the fixed panel is detachably mounted on the metal frame; the shielding structure is mounted on the fixed panel and covers the signal avoidance hole.

[0015] Specifically, the sheet metal base includes a base plate and a cover, wherein the base plate is detachably mounted on the metal frame; and the cover is detachably mounted on the base plate.

[0026] like Figure 1-3 As shown, the dual BT-WIFI structure of the vehicle host in this embodiment of the present invention includes a metal frame 10, a sheet metal bracket 20, an inner groove 30, a plastic panel 40, a BT-WIFI antenna 50, a circuit board 60, a sheet metal bottom shell 70, a signal avoidance hole 80, and a fixing screw 90.

[0027] The sheet metal bracket 20 is mounted on the metal frame 10, and the inner groove 30 is formed on the sheet metal bracket 20. The plastic panel 40 is detachably mounted on the metal frame 10. The circuit board 60 is set inside the metal frame 10. There are two sets of BT-WIFI antennas 50, each set of which is mounted on the circuit board 60. The sheet metal base shell 70 is set on the bottom wall of the metal frame 10. The signal clearance hole 80 is formed on the sheet metal base shell 70, and the fixing screws 90 are threadedly connected to the sheet metal base shell 70, the circuit board 60, and the metal frame 10.

[0028] It should be noted that the sheet metal bracket 20 and the metal frame 10 are integrally formed, and the inner groove 30 on the sheet metal bracket 20 is machined inward to avoid obstructing and interfering with the BT-WIFI antenna 50 signal, thereby improving the antenna signal strength, reducing cost and weight, and improving structural strength. The circuit board 60 is a PCBA board, and the two sets of BT-WIFI antennas 50 are respectively mounted on the circuit board 60. The plastic panel 40 is detachably mounted on the metal frame 10, and the plastic panel 40 is snap-fitted in place. During installation, it cooperates with the sheet metal base shell 70. Finally, the metal frame 10, plastic panel 40, circuit board 60, and metal frame 10 are connected together to form a whole by fixing screws 90.

[0029] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the plastic panel 40 includes a fixed panel 401 and a shielding structure 402.

[0030] The fixed panel 401 is detachably mounted on the metal frame 10, and the shielding structure 402 is mounted on the fixed panel 401, covering the signal avoidance hole 80.

[0031] It should be noted that the fixed panel 401 is snap-fitted onto the metal frame 10, and the shielding structure 402 covers the signal avoidance hole 80 during installation, thus effectively protecting the signal avoidance hole 80.
