The upper and lower covers snap together to form a housing, which contains a space for the remote control chip. The upper cover is equipped with a button. A key shaft is located at one corner of the upper and lower covers, connecting the key to the housing. The key can be rotated 180° around the shaft to fold the key. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the prior art and provide a completely different connecting rod key folding method, while integrating connecting rod additional accessories to realize a car folding remote control key with diversified functions.

[0004] The present invention is achieved through the following technical solution: a foldable car remote control key, comprising a base, a connecting rod assembly consisting of a driving rod, a driven rod, and a key, and a remote control assembly consisting of an upper cover, a lower cover, a remote control chip, and a button. The remote control assembly is characterized in that: the driving rod is provided with a rotatable annular blade, the driving rod and the driven rod are connected to the base by locking screws at one end and to the key at the other end, forming a retractable and foldable four-bar linkage with the base. The driving rod can rotate within a specific angle range on the base, and the key connected thereto drives the driven rod to rotate within a limited angle, thereby realizing the telescopic and folding function of the key. The upper and lower covers are fixed to the base by upper cover screws and snap together to form a housing, forming an internal space for accommodating the remote control chip, and the upper cover is provided with a button.

[0005] A limiting step is provided at the bottom of the base to limit the rotation angle of the connecting rod assembly and realize the extension and retraction positioning of the key.

[0006] The driving rod is provided with a blade slot and a retaining spring slot. The annular blade is placed in the blade slot and is enclosed in the blade slot by the retaining spring. Furthermore, the annular blade can rotate at a certain angle in the blade slot to realize the opening and retraction of the blade.

[0007] The driving rod rotation shaft is provided with a driving spring, and the driving spring is fixed on the base together with the driving rod by a locking screw, and a driving cam is provided on the rotation axis of the driving rod.

[0008] The driving spring is provided with a pressure plate, and a driving tip is provided at the end of the pressure plate, which cooperates with the driving cam of the driving rod to provide a driving elastic force, so that the driving rod automatically rotates to the maximum or minimum position after rotating past the critical state, thereby realizing automatic extension or retraction of the key. Furthermore, the driving spring is also provided with a stop spring plate, which is used to prevent the driving rod from retracting after the key is extended.

[0009] The beneficial effects of the present invention are: in the present invention, a completely different key folding method is realized, and a four-link telescopic mechanism is used for key folding. A rotatable blade is integrated on the main driving rod, and other instruments for other purposes can also be integrated as needed, so that the function of the remote control key can be expanded. A driving cam is provided on the rotating shaft of the main driving rod, which cooperates with the driving spring to provide a certain auxiliary rotational driving force for the extension and folding operations of the connecting rod assembly, and cooperates with the base limit step to enhance the operational fun and good experience of key extension and folding.

DETAILED DESCRIPTION

[0012] The present invention is described in detail below through examples. These examples are only used to further illustrate the present invention, but should not be understood as limiting the scope of protection of the present invention. Some non-essential improvements and adjustments made by those skilled in the art based on the above-mentioned contents of the present invention also fall within the scope of protection of the present invention.

[0013] Combine Figures 1 to 23 .

[0014] The foldable car remote control key comprises a base 1, a connecting rod assembly consisting of a driving rod 11, a driven rod 12, and a key 13, and a remote control assembly consisting of an upper cover 2, a lower cover 22, a remote control chip 4, and a button 21.

[0015] One end of the driving rod 11 and the driven rod 12 are connected to the base 1 by a locking screw 15, and the other end is connected to the key 13, forming a four-link telescopic mechanism with the base 1. The driving rod 11 can be pushed to rotate around the locking connecting screw 15 on the base 1, and the driven rod 12 is driven to rotate by the key 13 connected thereto. When the driving rod 11 rotates clockwise to the maximum position, the key 13 is extended. When the driving rod 11 rotates counterclockwise to the maximum position, the key 13 is retracted and folded.

[0016] A limiting step 14 is provided at the bottom of the base 1 to limit the rotation angle of the driving rod 11 , the driven rod 12 and the key, thereby realizing the extension and retraction positioning of the key 13 .

[0017] The upper cover 2 and the lower cover 22 are fixed to the base 1 by the upper cover screws 16 and snap together to form a shell, forming an internal containment space for accommodating the remote control chip 4. The upper cover 2 is provided with a button 21. The above components constitute a remote control assembly and are fixed to the base 1 by the upper cover screws 16.

[0018] The driving rod 11 is provided with an open blade groove 114 and a retaining spring groove 115. The annular blade 3 is placed in the blade groove 114, and the retaining spring 113 is placed in the retaining spring groove 115. Together with the blade groove 114, the annular blade 3 is constrained, so that the annular blade 3 can only rotate a certain angle in the blade groove 114, thereby realizing the opening and retraction of the cutting edge of the annular blade 3.

[0019] The driving rod 11 is provided with a driving spring 112 on its rotating shaft. The driving spring 112 is fixed to the base 1 together with the driving rod 11 by a locking screw 15 . A driving cam 111 is provided on the rotating shaft of the driving rod.

[0020] The driving spring 112 is provided with a pressure plate 1121, and a driving tip 1122 is provided at the end of the pressure plate 1121, which cooperates with the driving cam 111 of the driving rod 11 to provide driving elastic force. When the driving rod 11 is rotated, the cam top 1112 of its cam 111 passes the critical state of contact with the spring driving tip 1122, and the driving tip 1122 continuously applies pressure to the cam guide surface 1111 of the cam 111 to make it rotate, thereby driving the driving rod 11 to automatically rotate clockwise or counterclockwise, so that the key 13 is automatically extended or retracted.

[0021] The driving spring 112 is also provided with a stop spring 1123, which is used to prevent the driving rod 11 from retracting and rotating after the key 13 is extended. When the driving rod 11 rotates clockwise and drives the key 13 to be fully extended, the stop spring 1123 bounces upward, presses against the side of the driving rod 11, and limits its rotation, ensuring that the key 13 does not retract during the process of inserting into the keyhole. Pressing the stop spring 1123 releases the rotation restriction on the driving rod 11, allowing it to rotate counterclockwise, driving the key 13 back to the folded state.
