Description

Technical Field

[0001] This utility model relates to the field of dashcam technology, and in particular to a GPS antenna structure for dashcam products. Background Technology

[0002] A dashcam is a device installed inside or outside a car to record video and audio during driving. Generally, dashcams have a GPS antenna structure inside. However, there are usually two installation methods in the existing technology: (1) Make a separate GPS product and connect it to the dashcam with a data cable. However, this installation method will result in messy and excessively long external cables, which is not aesthetically pleasing and has a high cost; (2) Use an FPC antenna solution or GPS module solution to assemble inside the dashcam. Often, the dashcam will have poor signal due to interference from other circuits and chips because of other metal parts inside the dashcam; or, because the dashcam also needs to be assembled with a bracket for fixation, the dashcam is far away from the windshield of the car. When the dashcam adjusts the camera angle, it will rotate, resulting in an uncontrollable antenna orientation angle.

[0003] Therefore, designing a GPS antenna structure with a built-in GPS antenna that is not affected by interference from electronic components and metal parts has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in this embodiment, a GPS antenna structure for a dashcam product includes: a main unit 3, a flip-cover assembly 2, and a mounting bracket 1. The flip-cover assembly 2 is fixed on the mounting bracket 1, and the GPS antenna module 6 is fixedly installed inside the flip-cover assembly 2. The main unit 3 and the flip-cover assembly 2 are rotatably connected. A motherboard chip 32 is installed inside the main unit 3, and the motherboard chip 32 is communicatively connected to the GPS antenna module 6. By placing the GPS antenna module 6 separately on the mounting bracket 1, away from the metal parts, other circuits, and various chips inside the main unit 3, it can be installed close to the car windshield for easy installation. Furthermore, the GPS antenna remains stationary when the dashcam's main unit 3 rotates. Through the above design, interference and signal instability problems are solved, thereby improving GPS positioning performance and ensuring the stability of GPS antenna performance.

[0028] Furthermore, in this embodiment, the upper part of the flip cover assembly 2 is provided with a fixing groove 23, and the GPS antenna module 6 is fixedly installed in the fixing groove 23.

[0032] Furthermore, in this embodiment, the flip-top assembly 2 and the mounting bracket 1 are also fixedly connected by an adhesive layer 7. The mounting bracket 1 has adhesive layers 7 bonded to both its upper and lower surfaces for fixed connection to the automotive glass and the flip-top assembly 2. The adhesive layers 7 can be double-adhesive, using non-adhesive adhesives such as glue or soap, serving a fixed connection function.

[0033] Furthermore, in this embodiment, the host 3 is provided with a rotating shaft, and the rotating connection part 24 is mounted on the rotating shaft and rotatably connected to the host 3. This arrangement allows the host 2 to rotate and adjust when the dashcam needs to adjust the camera angle, while the mounting bracket 1 and the flip cover assembly 2 remain fixed together and unaffected by rotation. The GPS antenna's transmission direction remains unchanged, always perpendicular to the car's windshield, ensuring performance stability.

[0034] Furthermore, in this embodiment, a heat sink is also provided between the host 3 and the flip cover assembly 2.

[0035] Furthermore, the host 3 is also provided with a fixing bracket 31 inside, and the motherboard chip 32 is fixedly installed on the fixing bracket 31.

[0036] Furthermore, in this embodiment, a mounting slot is provided on one side of the host 3, and a battery 4 for providing power to the trip recorder is installed in the mounting slot.
