When the force column 32 at one end of the linkage member 3 is located in the third slot 1113, it is in a locked state and the lid is closed. When the rotating rod 2 is pressed for the first time, the seventh bevel 143 touches the force column 32 and cuts the force column 32 into the second slot 1112. The force column 32 enters the second slot 1112 from the third slot 1113. When the rotating rod 2 is released, the fourth bevel 154 touches the force column 32 and cuts the force column 32 into the second slot 1112.

Example

[0036] Combined with Figure 1-14Compared with the technical solution of Example 3, the opener and closer of this embodiment can be improved as follows: it also includes a locking structure 8, and the locking structure 8 is used to connect with the door controller. When the door is opened, the locking structure 8 contacts the bottom of the rotating rod 2, and when the door is closed, the locking structure 8 is separated from the bottom of the rotating rod 2. When it is necessary to open the lid, in this embodiment, the door controller is a key, and the door opening button on the key is pressed, and the locking structure 8 is separated from the bottom of the rotating rod 2. When one end of the rotating rod 2 is pressed, the rotating rod 2 moves and rotates, and at the same time drives the linkage 3 to move. The force column 32 at one end of the linkage 3 enters the second groove 1112 from the third groove 1113. When one end of the rotating rod 2 is released, the force column 32 at one end of the linkage 3 returns from the second groove 1112 to the first groove 1111, and the elastic member 7 is reset, and the rotating rod 2 The distance between one end of the rotating rod 2 and the column 6 increases.

The force-bearing column 32 at one end of the linkage member 3 enters the fourth groove 1114 from the first groove 1111. When one end of the rotating rod 2 is released, the force-bearing column 32 at one end of the linkage member 3 enters the third groove 1113 from the fourth groove 1114. At this time, the rotating rod 2 is locked, and the elastic member 7 is compressed again, and the distance between one end of the rotating rod 2 and the column 6 is reduced. By changing the distance from one end of the rotating rod 2 to the column 6, the purpose of opening and closing the lid is achieved. When the door closing button on the key is pressed, the locking structure 8 conflicts with the bottom of the rotating rod 2. At this time, even if one end of the rotating rod 2 is pressed, the rotating rod 2 cannot be moved, and the lid cannot be opened, which has the effect of electrically locking the lid. Example

[0037] Combined with Figure 1-14 Compared with the technical solutions of embodiment 3 or 4, the opening and closing device of this embodiment can be improved as follows: the locking structure 8 includes an electromagnet 81, a connector 82 and a lock rod 83 connected to the electromagnet 81, one end of the connector 82 is connected to the electromagnet 81, and the other end of the connector 82 is connected to the car door. When the door opening key on the key is pressed, the connector 82 generates a positive voltage, so that the electromagnet 81 generates a positive magnetic force, pushing the lock rod 83 to move away from the rotating rod 2, so that the lock rod 83 is separated from the bottom of the rotating rod 2. When the door closing key on the key is pressed, the connector 82 generates a negative voltage, so that the electromagnet 81 generates a reverse magnetic force, pushing the lock rod 83 to move toward the direction close to the rotating rod 2, so that the lock rod 83 conflicts with the bottom of the rotating rod 2. When the power is off, the lock rod 83 is held by the magnetic force of the electromagnet 81, thereby maintaining the original position. Example

[0038] Combined with Figure 1-14, compared with any one of the technical solutions of embodiments 4-5, the opener and closeer of this embodiment can be improved as follows: it also includes a puller 84, the end of the lock rod 83 away from the rotating rod 2 has a round hole, the second housing 5 is provided with a tension spring 52, one end of the puller 84 passes through the round hole and is fixed on the lock rod 83, and the other end of the puller 84 is wound around the tension spring 52 and extends to the inside of the instrument or the inspection cover of the engine compartment. When the car is out of power, the lock rod 83 cannot be controlled by the electromagnet 81. At this time, the puller 84 can be manually pulled to separate the lock rod 83 from the bottom of the rotating rod 2 to unlock the opener and closeer. Example

[0039] Combined with Figure 1-14 Compared with any one of the technical solutions of embodiments 4-6, the opening and closing device of this embodiment can be improved as follows: the top surface of the hanging platform has a round boss 24 for abutting the lid, the rotating rod 2 has an annular groove 21, and the end of the linkage member 3 connected to the rotating rod 2 has a clamping column 31 matched with the annular groove 21. When the rotating rod 2 moves, the rotating rod 2 drives the clamping column 31 to move through the annular groove 21, and the movement of the clamping column 31 drives the other end of the linkage member 3 to move in the control member 1, so as to change the distance between one end of the rotating rod 2 and the column 6, thereby realizing the opening and closing of the lid. Example

[0040] Combined with Figure 1-14 , the opening and closing device of this embodiment can be improved as follows compared with any one of the technical solutions of embodiments 4-7: the rotating rod 2 is provided with a rotating groove 22, the first housing 4 is provided with a through hole 41 for the rotating rod 2 to pass through, the upper end of the through hole is provided with a soft rubber ring 43, the soft rubber ring 43 prevents dust from falling into the first housing 4, and the side wall of the through hole 41 is provided with a guide column 42 that cooperates with the rotating groove 22. When the rotating rod 2 rotates and moves in the through hole 41 under the elastic force of the elastic member 7, the cooperation between the guide column 42 and the rotating groove 22 plays a role in that the rotating rod 2 rotates at different angles at different heights, and the locking and separation with the cover are achieved at different positions through the hanging platform 23 on the upper end surface of the rotating rod 2. Example

[0041] Combined with Figure 1-14 The opening and closing device of this embodiment can be improved as follows compared with any one of the technical solutions of embodiments 4-8: the electromagnet 81 is provided with a third housing 9, the outer wall of the second housing 5 is provided with a buckle 51, and the third housing 9 is provided with a clamping hole 91 that cooperates with the buckle 51. The second housing 5 and the third housing 9 cooperate with the buckle 51 with the clamping hole 91 to fix the electromagnet and facilitate disassembly.

[0042] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
