The "three shields" pattern in the BUICK trademark is a graphic trademark, which is the logo of the Buick division. It is mounted on the car radiator grille. In the picture, three bullets of different colors (from left to right: red, white, blue) and arranged at different heights give people a feeling of being aggressive and constantly climbing.

It means that the Buick Division adopts top-notch technology and is capable of cutting edge; it also means that the talents cultivated by the Buick Division are all capable and are invincible warriors with the courage to climb to the top. Since 2002, Buick's trademark has been changed to a concise form.

Buick's famous "Three Shields" logo is based on a circle containing three shields. Its origin can be directly traced back to the family crest of the Scotsman David Dunbar Buick, the founder of the automobile manufacturing industry. The entire trademark is an eagle with spread wings about to land on the English letters of Buick. It symbolizes that Buick is the ideal habitat for the eagle.

As a survey conducted in the 1890s by the Scotch Company, a company engaged in corporate image research, showed that its role as a symbolic pattern is of great importance.

In the investigation and research on company trademarks, it was found that the company's trademarks can have a positive or negative impact on customers. The survey further shows that among many automobile manufacturers, the "three shields" logo of GM Buick products has won 50% of favors, which is an eye-catching proportion.
