Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective shell technology, specifically a car key protective shell. Background Technology
[0002] Most car keys are hard-shell structures with a built-in car smart remote control. There are no protective devices on the key shell. Due to frequent use, they are prone to being dropped or bumped, resulting in severe wear and tear on the key's exterior. In some cases, the remote control device inside the key may even be damaged. Therefore, car key protective shells have emerged.
[0003] For example, Chinese patent CN209976195U discloses a car key protective case, including an upper cover and a lower cover. A cavity for placing a car key is formed between the upper cover and the lower cover. The upper cover and the lower cover are provided with mutually cooperating protrusions and recesses. A central ring is also provided at the joint between the upper cover and the lower cover to prevent misalignment when the protrusions and recesses are engaged. This car key protective case makes it more convenient to install and remove car keys.
[0004] Although the aforementioned patent makes it easier to install and remove car keys with the car key protective shell, and the patent uses at least two interlocking protrusions and recesses to fix the upper and lower covers together, when the car key protective shell is dropped on the ground, the at least two protrusions and recesses may separate, thus separating the upper and lower covers and reducing stability.
