[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figure 1-Figure 8As shown, an electronic lock includes a lock tongue driving mechanism and a lock tongue 1, wherein the lock tongue driving mechanism includes a rotatable turntable 4, a pusher 2 for pushing the lock tongue 1 to reciprocate linearly, and a pressing member 3 for driving the extended end of the lock tongue 1 to press downward;

[0031] The rotating disk 4 is provided with a rotating shaft 401 coaxially rotating with the rotating disk 4, and an arc-shaped guide groove 402 is provided around the rotating shaft 401 on the rotating disk 4. The arc-shaped guide groove 402 includes an arc-shaped segment 403 with a radius gradually increasing from the rotating shaft 401 and a circular ring segment 404 coaxial with the rotating shaft 401. One end of the pusher 2 is connected to the lock tongue 1, and the other end is slidably arranged in the arc-shaped guide groove 402;

[0032] A spiral piece 405 is provided on the outer wall of the rotating shaft 401, and a lifting groove 406 is provided on the upper part of the lower pressing piece 3, and the lower part cooperates with the spiral piece 405 and the spiral piece 405 can drive the lower pressing piece 3 to move up and down under the rotation of the rotating shaft 401;

[0033] When the pushing member 2 moves in the arc segment 403 , the pressing member 3 does not contact the spiral piece 405 . When the pushing member 2 moves in the annular segment 404 , the pressing member 3 and the spiral piece 405 move in coordination with each other.

[0034] The present embodiment also includes a lock case 6, which includes a housing 601 and a lock cover 602. The bolt drive mechanism also includes a turntable drive mechanism, which includes a drive motor 5 and a gear set 7 connected to the output shaft of the drive motor 5. The outer side surface of the turntable 4 opposite to the arc-shaped guide groove 402 is provided with a tooth block meshing with the gear set 7.

[0035] Among them, the turntable 4, the pushing member 2, the pressing member 3 and the gear set 7 are all arranged in the shell 601, the lock tongue 1 is arranged on the lock cover 602, the motor is fixed on the outer wall of the shell 601 and the output shaft extends into the shell 601 and meshes with the gear set 7, and the lock cover 602 is provided with a lock tongue mounting groove 603 connected to the inside of the shell 601, and the length direction of the lock tongue mounting groove 603 is arranged along the extending direction of the lock tongue 1, the lock tongue 1 is slidably arranged in the lock tongue mounting groove 603 and the end of the lock tongue 1 can slide out of the lock shell 6 along the inner wall of the lock tongue mounting groove 603.

[0036] During use, the motor drives the turntable 4 to rotate around the rotating shaft 401 through the gear set 7. Under the rotation of the turntable 4, the pusher 2 begins to slide in the arc segment 403 of the arc guide groove 402 on the turntable 4. Since the radius of the arc segment 403 from the rotating shaft 401 gradually increases, the pusher 2 will be driven to move under the action of the turntable 4, and the pusher 2 drives the lock tongue 1 to extend out of the lock shell 6 in a straight line; as the pusher 2 runs to the annular segment 404 of the arc guide groove 402, since the annular segment 404 is coaxially arranged with the rotating shaft 401, the pusher 2 will not continue to drive the lock tongue 1 to extend. At this time, the turntable 4 continues to rotate and the spiral piece 405 rotates to the lower pressing piece, and the spiral piece 405 drives the lower pressing piece 405 to move. The pressing piece rises, thereby lifting the end of the lock tongue 1, and the extended end of the lock tongue 1 performs a downward pressing action, thereby completing the two actions of linear extension of the lock tongue 1 and downward pressing of the extended end. During its specific use, the electronic lock is installed on both sides of the flip display screen on the top of the car, with the lock tongue facing the display screen. A storage slot for accommodating the flip display screen is provided on the top of the car, and a lock hole matching the lock tongue is provided on the side surface of the lower end of the flip display screen. When the flip display screen is stored in the storage slot, the lock tongue extends out and extends into the lock hole, and then performs a downward pressing action (in the actual process, the display screen is squeezed toward the inside of the storage slot), and finally the lower surface of the flip display screen is on the same plane as the outer frame surface of the storage slot, thereby ensuring the overall aesthetics of the car interior.

[0037] In this embodiment, a long strip-shaped mounting groove 101 is provided on the lock tongue 1, and the mounting groove 101 extends from the end of the lock tongue 1 away from the protruding end to the middle of the lock tongue 1. Oppositely arranged mounting holes 102 are provided on the two side walls of the mounting groove 101. The pushing member 2 includes a pushing plate 201 which is arranged in the mounting groove 101 and whose end face abuts against the end face of the mounting groove 101. The pushing plate 201 is provided with a mounting column 202 installed in the mounting hole 102. The bottom surface of the pushing plate 201 is connected to a sliding column 203 which is slidably arranged in the arc guide groove 402.

[0038] The structural design of the push member 2 enables it to be conveniently connected to the lock tongue 1 and the push member 2 is arranged in the installation groove 101 in the middle of the lock tongue 1. It is not only compact in structure, but also can apply force to the lock tongue 1 in the center, so that it can apply force to the middle of the lock tongue 1 more evenly under the action of the turntable 4, avoiding eccentric force on the lock tongue 1, making the linear motion of the lock tongue 1 more stable; in addition, the lower part of the push member 2 is designed in the form of a sliding column 203, so that it can better cooperate with the arc guide groove 402 to slide, and the cooperation of the arc surfaces of the sliding column 203 and the arc guide groove 402 realizes smooth and stable linkage between the two.

[0039] In this embodiment, the pressing member 3 includes a U-shaped lifting block 301 with an opening upward, and a lifting groove 406 is formed in the middle of the U-shaped lifting block 301. The U-shaped lifting block 301 includes a bottom plate 302 and two side plates 303. A fixed pin 103 is provided on the side surface of the end of the locking tongue 1 away from the protruding end, and a U-shaped groove 304 is provided on the side surface of the side plate 303. The fixed pin 103 can follow the locking tongue 1 and move linearly into the U-shaped groove 304 under the action of the pushing member 2; a connecting block 305 is provided on the bottom surface of the bottom plate 302, and a lifting shaft 306 axially arranged along the radial direction of the turntable 4 is connected to the connecting block 305, and the lifting shaft 306 cooperates with the spiral piece 405 to realize the up and down movement of the pressing member 3.

[0040] In addition, a plug hole 307 is provided on the connecting block 305 and an arc groove 308 connected to the plug hole 307 is provided on the bottom surface.

When the plug rod 309 is inserted into the plug hole 307, the upper part of the lifting shaft 306 is stuck in the arc groove 308.

[0041] The upper part of the pressing piece 3 is constructed in a U shape, and a U-shaped lifting groove 406 is formed in the middle part, which can not only provide a certain support for the lock tongue 1, but also guide the movement of the lock tongue 1, so that the lock tongue 1 can move more accurately and smoothly out of the lock shell 6; in addition, a U-shaped groove 304 is constructed on the side of the side plate 303 of the U-shaped lifting block 301, so that it can cooperate with the fixing pin on the lock tongue 1 when lifting the end of the lock tongue 1, so as to realize the rotation of the lock tongue 1 around the fixing pin shaft 103, and limit the end of the lock tongue 1 during the rotation process to ensure the accurate stability of the downward pressure of the extended end of the lock tongue 1.

[0042] In addition, a lifting shaft 306 is provided at the bottom of the lower pressure piece 3, and the connection method between the lifting shaft 306 and the U-shaped lifting block 301 makes it easy to connect, and the upper part of the lifting shaft 306 is placed in the lifting groove 406, which reduces the occupied space and avoids interference with adjacent components such as the gear set 7, the rotating shaft 401, etc., which affects the extension movement of the front part of the lock tongue 1, and can prevent it from rotating during the lifting process, thereby ensuring the stable lifting process. It also has the characteristics of compact structure and easy installation.

[0043] The side of the lock tongue mounting groove 603 is a stepped surface 605 including two vertical surfaces 604 and a stepped horizontal surface. The stepped horizontal surface is provided with a guide groove 606 for the upper end of the push member 2 to extend out. The lock tongue 1 is slidably arranged between the two inner vertical surfaces 604. The structural arrangement of the lock tongue mounting groove 603 enables it to provide a guiding effect for the reciprocating motion of the lock tongue 1, and to provide an accommodation space for the fixing pin, the push member 2, etc. arranged on the lock tongue 1, so that the entire lock tongue 1 and its related connecting mechanism can be well arranged in the lock cover 602. In addition, the arrangement of the guide groove 606 on the stepped surface 605 enables the U-shaped lifting block 301 to keep rising in a straight line under the action of the spiral piece 405, thereby realizing a linear guiding effect on the up and down movement of the pressing member 3, and then ensuring that the lock tongue 1 can be pressed down accurately.

[0044] In this embodiment, a lock tongue cover 607 covering the lock tongue installation groove 603 is installed on the lock cover 602, and a lock tongue extension groove 608 is provided at the end of the lock tongue cover 607 and the end of the lock cover 602. The lock tongue extension groove 608 together constitutes a lock tongue extension hole 609 for the lock tongue 1 to slide out of the lock shell 6. The arrangement of the lock tongue cover 607 can make the entire electronic lock more complete and beautiful, and at the same time can also protect the lock tongue 1 component to prevent foreign objects from falling into and affecting the movement of the lock tongue 1.
