Technical Field

[0001] This invention relates to the field of automotive key technology, and more particularly to an automotive key. Background Technology

[0002] As electric vehicles mature, smart keys have integrated many new functions, such as smart location, unlocking, and fingerprint recognition. Traditional car keys, however, have an external pendant ring, making smart keys bulky and unsuitable for diverse consumer preferences. Therefore, whether the pendant ring is retained or removed, and the resulting differences in key appearance, neither approach can cater to all consumer habits. Furthermore, manufacturing different key designs would require new molds, increasing production costs and wasting resources.

[0003] Therefore, there is an urgent need to provide a car key that can solve the aforementioned technical problems in the prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a car key with a simple structure, which allows users to switch the state of the car key according to their own preferences, realize the hiding and activation of the pendant ring, and reduce production costs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The car key includes a key body and a pendant ring. The key body has a receiving groove on its side wall, and a limiting step protrudes from the inner side wall of the receiving groove along a first direction. The pendant ring is fitted into the receiving groove and is slidably connected to the receiving groove along a second direction. A limiting part is provided at one end of the pendant ring along the second direction and near the bottom wall of the receiving groove. The limiting part can abut against the limiting step along the second direction. The bottom wall of the groove and the limiting part are detachably connected. The first direction and the second direction are perpendicular to each other.

[0007] Optionally, the pendant ring includes a connecting portion extending along the second direction, and the connecting portion is integrally formed with the limiting portion.

[0008] Optionally, two limiting steps are provided, and the two limiting steps are disposed opposite to each other on the inner sidewall of the receiving groove along the first direction.

[0009] Optionally, the limiting portion protrudes from both ends of the connecting portion along the first direction, so that the limiting portion and the connecting portion are formed into a T-shaped structure.

[0010] Optionally, a pendant portion is provided at the end of the connecting portion away from the limiting portion, and the pendant portion has a pendant hole.

[0011] Optionally, a pull-out structure is provided at the end of the pendant portion away from the limiting portion, and the pull-out structure always protrudes from the port of the receiving groove.

[0012] Optionally, the bottom wall of the groove is magnetically connected, bonded, or snap-fitted to the limiting part.

[0013] Optionally, the bottom wall of the groove is provided with a first magnetic sheet, and the limiting part is provided with a second magnetic sheet that attracts the first magnetic sheet.

[0014] Optionally, the key body includes an upper cover and a lower cover that interlock with each other.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0028] The first direction in this embodiment is Figures 1 to 3 The X direction shown is the width direction of the key body 100; the second direction is... Figures 1 to 3 The Y direction shown is the length direction of the key body 100; the first direction and the second direction are perpendicular to each other.

[0029] Please refer to Figure 1 and Figure 2 In this embodiment, the car key includes a key body 100 and a pendant ring 200. The key body 100 has a receiving groove 110 on its side wall, and a limiting step 111 protrudes from the inner side wall of the receiving groove 110 along a first direction. The pendant ring 200 is fitted into the receiving groove 110 and is slidably connected to the receiving groove 110 along a second direction. A limiting part 210 is provided at one end of the pendant ring 200 along the second direction and near the bottom wall 112 of the receiving groove 110. The limiting part 210 can abut against the limiting step 111 along the second direction. The bottom wall 112 of the groove and the limiting part 210 are detachably connected.

[0030] In this embodiment, the car key's pendant ring 200 is housed within the receiving groove 110 of the key body 100, thus concealing the pendant ring 200. The pendant ring 200 can slide along the receiving groove 110 in a first direction, allowing it to be pulled out and connected to an external structure, thus serving as a car key pendant. During the pulling-out process, a limiting part 210 is provided at one end of the pendant ring 200 within the receiving groove 110. This limiting part 210 abuts against a limiting step 111 protruding from the inner sidewall of the receiving groove 110, preventing excessive displacement of the pendant ring 200 and causing it to detach entirely. This improves ease of use and ensures the reliability of the pendant during use. The car key in this embodiment features a pendant ring 200 that can be concealed or pulled out, has a simple structure, and is suitable for different users' needs. It eliminates the need for multiple molds to produce different types of car keys, reducing production costs.

[0031] Please refer to Figure 3 Optionally, the pendant ring 200 includes a connecting portion 220 extending along the second direction, and the connecting portion 220 is integrally formed with the limiting portion 210. The connecting portion 220 allows the pendant ring 200 to extend further out of the receiving groove 110, facilitating the attachment of the pendant ring 200 to an external device.

[0032] Furthermore, two limiting steps 111 are provided, and the two limiting steps 111 are disposed opposite to each other on the inner sidewall of the receiving groove 110 along the first direction. The provision of two limiting steps 111 can make the limiting part 210 more stably blocked, further preventing the pendant ring 200 from falling off; and can also keep the car key balanced when hooked, preventing it from falling off, thus increasing the reliability and service life of the car key.

[0033] In a preferred embodiment, the limiting portion 210 protrudes from both ends of the connecting portion 220 along the first direction, so that the limiting portion 210 and the connecting portion 220 are formed into a T-shaped structure. The T-shaped structure of the limiting portion 210 and the connecting portion 220 can reduce the processing difficulty and further ensure the reliability of the limiting portion 210 when it abuts against the two limiting steps 111.

[0034] Please continue to refer to this. Figure 3 The connecting part 220 is provided with a pendant part 230 at the end away from the limiting part 210, and the pendant part 230 has a pendant hole 231. The pendant part 230 is generally "U" shaped, and the pendant hole 231 is used to hang the pendant ring 200 on the hook of the external structure, so as to realize the stable and reliable hanging of the car key.

[0035] Alternatively, a pull-out structure 232 is provided at the end of the pendant portion 230 away from the aforementioned limiting portion 210, and the pull-out structure 232 always protrudes from the port of the receiving groove 110. This pull-out structure 232 protruding from the receiving groove 110 allows the pendant ring 200 to be easily pulled out, facilitating user use.

[0036] In this embodiment, the bottom wall 112 of the groove is magnetically connected, bonded, or snap-fitted to the limiting part 210. This connection method is simple, reliable, and easy to manufacture, enabling a stable connection between the bottom wall 112 of the groove and the limiting part 210, preventing the pendant ring 200 from accidentally falling off, and facilitating the pulling out of the pendant ring 200, thus improving the user experience.

[0037] Specifically, in this embodiment, a magnetic connection is used between the bottom wall 112 of the groove and the limiting part 210. Optionally, the bottom wall 112 of the groove is provided with a first magnetic sheet 113, and the limiting part 210 is provided with a second magnetic sheet 211 that attracts the first magnetic sheet 113. Further, one of the first magnetic sheet 113 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 113 and the second magnetic sheet 211 are two magnets with opposite polarities attracting each other, which can realize the magnetic connection between the limiting part 210 and the bottom wall 112 of the groove. The magnetic connection method occupies little space, has high connection stability, is easy to disconnect, has a long service life, and is simple and pollution-free to process, which will not be elaborated here.

[0038] Optionally, the key body 100 includes an upper cover and a lower cover that interlock. Further, the upper cover and the lower cover are connected by a locking screw 120. The interlocking of the upper and lower covers provides a good seal, isolating and protecting the electrical structure inside the key body 100 from the external environment, thus providing the car key with good waterproof, dustproof, and anti-static properties. Specifically, using the locking screw 120 to connect the upper and lower covers not only provides a good fixation effect but also facilitates disassembly, thereby efficiently maintaining the internal electrical structure and reducing maintenance costs.
