What does 'Ding Che' mean?

[GriffinRose]

Ding Che might refer to a convertible car. Below is relevant information about car roofs: 1. Introduction to car roofs: The car roof is the cover panel on top of the passenger compartment. For the overall rigidity of a car body, the roof is not a very critical component, which is why it is permissible to install sunroofs on car roofs. 2. Features of car roofs: The components of a hardtop convertible fit together with considerable precision, and the entire electronic control mechanism is quite complex. However, due to the use of rigid materials, the sealing is better when the roof is restored. On the other hand, a soft-top convertible consists of a fabric cover and a supporting frame, which can be folded backward to achieve an open passenger compartment. Because the fabric is soft, it folds more compactly, and the entire mechanism is relatively simpler, but the sealing and durability are poorer.
