[0029] Reference should be made to Figures 1 to 2In the embodiment, the smart key comprises a key body 100 and a pendant ring 200. The key body 100 comprises a protruding portion 110, and a receiving groove 120 is recessed in the protruding portion 110. A rotating shaft 121 is arranged in the receiving groove 120 along the thickness direction of the protruding portion 110. The pendant ring 200 is configured to be fitted into the receiving groove 120 and is rotationally connected with the rotating shaft 121. The bottom wall 210 of the pendant ring 200 is detachably connected with the bottom wall 122 of the receiving groove 120, and at least one of the side walls 220 of the pendant ring 200 is arranged not lower than the outer edge side wall 111 of the protruding portion 110.

[0030] In the embodiment, the smart key comprises a key body 100 and a pendant ring 200. The key body 100 comprises a protruding portion 110, and a receiving groove 120 is recessed in the protruding portion 110. A rotating shaft 121 is arranged in the receiving groove 120 along the thickness direction of the protruding portion 110. The pendant ring 200 is configured to be fitted into the receiving groove 120 and is rotationally connected with the rotating shaft 121. The bottom wall 210 of the pendant ring 200 is detachably connected with the bottom wall 122 of the receiving groove 120, and at least one of the side walls 220 of the pendant ring 200 is arranged not lower than the outer edge side wall 111 of the protruding portion 110.

[0031] The smart key in the embodiment is specifically a smart key for a car, and the surface of the smart key is provided with a case or a display screen for controlling the car, which is not specifically limited herein.

[0032] Optionally, the key body 100 comprises an upper cover and a lower cover which are mutually buckled. Further, the upper cover and the lower cover are connected by locking screws. The upper cover and the lower cover are buckled, which can achieve good sealing, so that the electrical structure in the key body 100 is protected from the external environment, thereby making the smart key have good waterproof, dustproof and anti-static effects. Specifically, the upper cover and the lower cover are connected by locking screws, which not only has good fixing effect, but also is convenient for disassembly, thereby efficiently maintaining the internal electrical structure and reducing maintenance cost.

[0033] Specifically, please continue to refer to Figure 1 and Figure 2The key body 100 has a rectangular cross-section, and the pendant ring 200 has a fan-shaped cross-section. In this embodiment, the key body 100 is approximately cuboid with rounded corners. The protrusion 110 is one corner of the cuboid key body 100, thus forming a fan-shaped receiving groove 120. The pendant ring 200 corresponding to the receiving groove 120 is also fan-shaped, which will not be described in detail here. Those skilled in the art can set the shapes of the key body 100, the protrusion 110, the receiving groove 120, and the pendant ring 200 according to specific needs, and no specific limitations are made here.

[0034] Please continue to refer to this. Figure 2 and Figure 3 Both the bottom wall 210 of the ring and the bottom wall 122 of the groove are arc-shaped, and there is a gap of a predetermined width between them. Setting the bottom wall 210 and the bottom wall 122 to be arc-shaped, with a predetermined gap between them, prevents the bottom wall 210 of the ring and the bottom wall 122 of the groove from colliding when the pendant ring 200 rotates, thus providing a collision avoidance function and facilitating user operation.

[0035] Furthermore, the aforementioned ring bottom wall 210 and the aforementioned groove bottom wall 122 are magnetically connected, adhesively bonded, or snap-fitted together. Alternatively, protrusions can be provided on the ring bottom wall 210 and the groove bottom wall 122 to abut against each other, using friction to fix the ring bottom wall 210 and the groove bottom wall 122; this will not be elaborated further here. The above connection method is simple, reliable, and easy to manufacture, achieving a stable connection between the groove bottom wall 122 and the ring bottom wall 210, preventing the pendant ring 200 from accidentally being pushed out of the groove 120, and facilitating the rotation and ejection of the pendant ring 200, thus improving the user experience.

[0036] Optionally, the annular bottom wall 210 is provided with a first magnetic sheet 123, and the groove bottom wall 122 is provided with a second magnetic sheet 211 that attracts the first magnetic sheet 123. Further, one of the first magnetic sheet 123 and the second magnetic sheet 211 is a magnet, and the other is an iron sheet or a magnet with opposite magnetic properties. In this embodiment, the first magnetic sheet 123 and the second magnetic sheet 211 are two magnets with opposite polarities attracting each other, enabling a magnetic connection between the annular bottom wall 210 and the groove bottom wall 122. Magnetic connection occupies little space, has high connection stability, is easy to disconnect, has a long service life, and is simple and pollution-free to process; further details are omitted here.

[0037] Specifically, the aforementioned pendant ring 200 has a pendant hole 230 along the axial direction of the aforementioned rotating shaft 121. The pendant ring 200 is generally "U" shaped, and the pendant hole 230 is used to hang the pendant ring 200 on the hook of the external structure, so as to achieve stable and reliable hanging of the smart key.

[0038] As a preferred embodiment, the inner side wall of the pendant hole 230 comprises at least one arc wall 231. In this embodiment, the pendant hole 230 comprises two arc walls 231 arranged oppositely and in parallel, so that the pendant hole 230 and the solid part formed by the pendant ring 200 have uniform wall thickness, the stress generated when the wall surface of the pendant hole 230 is opened, prolongs the service life of the pendant ring 200; and the pendant hole 230 provided with the arc wall 231 will not be abraded when hung on the external structure, further prolonging its service life.

[0039] As shown in Figure 4 The pendant hole 230 is also arranged through the ring side wall 220 in the rotation direction of the pendant ring 200. The pendant ring 200 arranged in this way has a hollow structure with four open holes, which can reduce the weight of the pendant ring 200 and the smart key, facilitate the user to carry, and also reduce the raw material cost, which will not be described here.

[0040] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the scope of the present application. Here, it is not necessary and impossible to exhaust all the embodiments. Any modification, equivalent substitution and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
