Description

Technical Field

[0001] The utility model relates to the technical field of automobile steering, in particular to a steering wheel indicator. Background Art

[0002] With the increasing popularity of cars, more and more people own cars, and driving lessons are essentially a necessity. However, during driving practice, the steering wheel turns 1.5 turns to the left and right. Therefore, after one turn, new drivers, due to lack of experience and nervousness, cannot tell whether the steering wheel is straight or has completed one full turn. This can cause confusion, leading to traffic jams or accidents.

[0003] As a result, some steering wheel position indicator devices have appeared on the market to help novice drivers confirm the actual steering wheel rotation angle during their initial driving experience. However, most current steering wheel position indicator devices are integrated and use gravity sensing to attach the device to the steering wheel, which poses two problems:

[0004] If the product is attached to the steering wheel and used, when the steering wheel is turned exactly 180 degrees, the product will be completely blocked from view at the lower position. Even if it is not 180 degrees, as long as the steering wheel is turned, the product will be at the lower position, making it difficult to view the product's indication status, and even causing the driver to lower his head to confirm, which is more dangerous.

[0005] To this end, a steering wheel indicator is proposed. Utility Model Content
