[0020] The specific embodiments of the present application will be described below with reference to the drawings, which show the shape of each component, the configuration, the mutual position and connection relationship between the parts, the function and working principle of each part, the manufacturing process, and the method of operation and use, and so on, to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solutions of the present application.

[0021] The key body of the automobile key structure is in the flat cuboid structure, which is no different from the conventional key. The key body is provided with a key compartment recessed inward at one end for placing the mechanical key 11. Considering that the blade cover 1 part is small, if it can still be connected with the key body after being opened, it will not be worried about being accidentally lost. Therefore, it is designed as a "door" structure, and the blade cover 1 is a "door" sealed outside the key compartment. The mechanical key 11 is inserted and placed in the key compartment. The key compartment is provided with a rubber layer on one side. The rubber layer is used to clamp the mechanical key 11. When the mechanical key 11 is inserted into the key compartment, they are tightly matched. In this way, when the blade cover 1 is opened, the mechanical key 11 will not directly fall off due to too loose, which may cause the mechanical key 11 to be lost. The mechanical key 11 is L-shaped, the longer main body is provided with a key at one end, and the shorter end is provided with a handle. The thickness and width of the key and the handle are the same.

[0022] When people use such small mechanical keys 11, they will feel very inconvenient because the shorter end is too short and lacks a "lever" for turning the key. Therefore, the thickness and width of the key and the handle are designed to be the same. When using the mechanical key 11, press the button 10 to open the blade cover 1, and then pull out the mechanical key 11. Insert the handle of the mechanical key 11 into the key compartment. Because the handle is short, it can only be inserted into a shallow position, but the key body can be used as the key handle of the mechanical key 11. The thickness and width of the key and the handle are the same, so the key compartment can firmly hold the handle, and the entire key body can be used as the key handle of the mechanical key 11, which is more labor-saving when using the mechanical key 11.

[0023] The key compartment is sealed by the blade cover 1. The structure of the blade cover 1 is as follows: Figure 2As shown, the tooth cover 1 is zinc alloy-plated based on the appearance requirements, meeting the customer's requirements for metallic texture and the strength of the part itself. The tooth cover 1 has an axial hole 2 at one end, through which it is mounted on the fixed shaft of the key body. The outer surface of the tooth cover 1 is a cover plate 4, and the inner surface is provided with a lock tooth 5, which engages with a lock catch 9 in the key body. The lock catch 9 and the lock tooth 5 are L-shaped structures that bend toward each other, with both ends being wedge-shaped. This allows for better locking by pressing the cover seal to automatically engage the lock catch 9 and the lock tooth 5. The tooth cover 1 has two lock teeth 5 and the key body has two lock locks, connected by two snap positions for a more secure connection. Both lock catches are fixed to a connecting rod, one end of which is connected to a button 10 on the side of the key body and the other end is supported by a return spring 8. In this way, when the button 10 is pressed, the lock buckle 9 moves in the same direction to unlock the lock tooth 5 and the lock buckle 9. After unlocking, the connecting rod, button 10, and lock buckle 9 are all returned to their original positions by the rebound force of the return spring 8. The opened tooth cover 1 can be directly pressed to press the lock tooth 5 directly into the lock buckle 9 to complete the locking.

[0024] The key's appearance requires a small and uniform clearance when the tooth cover 1 is rotated closed. The opening process must be smooth and free of interference or friction with other components. The fixed shaft is cylindrical, and the shaft hole 2 is an arc-shaped hole that is wide in the middle and gradually narrows towards the sides. In other words, the portion of the tooth cover 1 that fits over the shaft is designed to resemble an isosceles right triangle. The two acute angles are where the shaft mates with the shaft when closed and opened to the limit. To ensure the entire key's sealing, the edge of the tooth cover 1 is provided with a rubber pad, and the button is a rubber block, which provides a certain degree of sealing at the movable connection. The rubber block button acts as a plug, providing a better seal. Furthermore, the other end of the tooth cover 1 is provided with an end plate 6, which contacts the button 10. This not only reduces a movable edge (the end plate 6 and button 10 are connected and share a side), improving sealing performance, but also allows the finger pressing the button 10 to push the end plate 6, facilitating the opening of the tooth cover 1 and simplifying the cover-opening operation.

[0025] The toothed cover 1 is made of metal, preferably a reinforcing flange 3 is arranged at the edge of the shaft hole 2, which is used to strengthen the strength of the toothed cover 1 as a lever part, avoiding the toothed cover 1 from being deformed due to long-term use as a crowbar. One end of the fixing shaft is fixed on the key body, and the other end is sealed by the battery cover plate 4. A battery cover buckle 7 which is used to connect the key body and the battery cover plate 4 is arranged beside the fixing shaft. The battery cover buckle 7 is used as a breakthrough to open the battery cover plate 4. The opening method is to press the button 10 to open the toothed cover 1, pry the toothed cover 1 in the direction of the battery cover plate 4 to open the battery cover buckle 7, and pry the whole battery cover plate 4 through the opening of the battery cover buckle 7. The toothed cover 1 is used as a crowbar. When the customer needs to replace the battery, the toothed cover 1 is rotated to the maximum position, and then an angle is prised in the direction of the battery cover, the battery cover is prised up by the lever principle, the buckle is separated, and the battery cover can be disassembled without borrowing external objects, which is more convenient to use.

[0026] The above describes the present application in conjunction with the drawings, and it is obvious that the specific implementation of the present application is not limited by the above method. Any non-essential improvement or direct application of the concept and technical solution of the present application to other occasions is within the protection scope of the present application.
