Technical Field

[0001] The utility model relates to a guiding structure, in particular to a guiding structure of a Beidou positioning chip. Background Art

[0002] The Beidou positioning chip is an integrated circuit designed specifically for the Beidou satellite navigation system. It receives Beidou satellite signals and calculates position information. The Beidou satellite navigation system is China's independently developed global satellite navigation system, similar to the US GPS, Russia's GLONASS, and the EU's Galileo system. With technological advancements, Beidou positioning chips will continue to develop towards higher integration, lower power consumption, higher accuracy, and greater security.

[0003] Although the existing Beidou positioning chips have made significant technological progress, they still have some shortcomings in actual use, as follows:

[0004] Fixed location leads to lack of flexibility: Beidou positioning chips are usually installed on devices. However, due to the fixed installation location, the direction of the receiving antenna cannot be flexibly adjusted in some cases. For example, between high-rise buildings in cities or in densely forested areas, the fixed installation location may not provide optimal satellite signal reception.

[0005] Heat accumulation: Under high load or long-term operation, fixed Beidou positioning chips may generate a lot of heat. If not dissipated in time, it may cause chip performance degradation or even damage. This problem is particularly prominent in enclosed spaces with poor heat dissipation conditions.

[0006] Therefore, a guidance structure for a Beidou positioning chip is particularly needed to solve the above problems. Utility Model Content

The electric push rod is installed on the left side of the middle end of the connecting rod, and the telescopic rod of the electric push rod is fixedly connected to the bottom of the connecting seat.

[0010] Furthermore, the heat dissipation component includes a thermal pad and a radiator. The connecting seat is provided with multiple ventilation holes in a circular array.
