[0003] With the development and changes in the design concept of car keys, especially the rise of smart cars such as electric cars and hybrid cars, car keys have gradually deviated from the scope of traditional keys, with more and more intelligent functions and larger internal circuit modules. Therefore, the space for mechanical keys in smart key boxes is getting smaller and smaller, requiring mechanical keys to be more and more miniaturized. The structure of mechanical keys has also changed. However, the size of mechanical keys is too small. After inserting them into the car door lock, it is difficult for fingers to apply force, which makes the operation very inconvenient and the use effect is not ideal. Summary of the invention

[0004] The purpose of the utility model is to provide a miniaturized folding mechanical key, which adopts a folding mechanical key structure and is easy to operate without affecting miniaturization.

[0005] The technical solution of the utility model is a miniaturized folding mechanical key, which comprises a key blank, one end of which is connected to a metal head, and a folding handle is connected to a portion of the key blank close to the metal head.

[0006] In the above-mentioned miniaturized folding mechanical key, the key blank is connected to the handle via rivets and gaskets.

[0007] In the above-mentioned miniaturized folding mechanical key, the rivet mounting hole of the key blank is provided with a receiving groove, and the handle is provided with a matching boss.

[0008] In the above-mentioned miniaturized folding mechanical key, one end of the key blank is provided with a hole, and the hole is connected to the mounting groove of the metal head by a screw.

[0009] Beneficial effects: The miniaturized folding mechanical key of the utility model has a metal head connected to one end of the key blank, and has a small external size. It is suitable for smart car key boxes with exquisite appearance and large circuit boards, and meets the current requirements for refined key design. A folding handle is connected to the mechanical key to ensure the integrity of the appearance of the smart key and the convenience of using the mechanical key. When not in use, the handle of the mechanical key is retracted, and the mechanical key is assembled as a whole in the smart key housing; when the key is needed, the mechanical key is pulled out and the handle is rotated to the maximum angle, which is convenient for the customer to rotate and operate the key to unlock and lock. Compared with the prior art, the utility model has a reasonable structure, exquisite appearance, and is easy to use, which ensures the convenience of using the car key and the integrity of the appearance.
