[0002] With the development of technology and people's pursuit of convenience, the demand for automated locks is increasing. Automated locks can reduce manual operation and improve efficiency, especially in parts that require frequent opening and closing, such as luggage compartment locks on buses. In existing electric latch locks, the actuating element is used to drive the bolt to rotate for locking and unlocking. Because the actuating element and gear are always in a meshed state, the electric latch lock cannot be manually unlocked in an emergency. Summary of the Invention

[0003] In view of this, the present invention provides a gear-driven electric suction lock to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0004] The technical solution of this utility model embodiment is implemented as follows: A gear-driven electric suction lock includes a housing, the housing having a first lock opening, the housing including a first base and a second base, the first base having a deflectable locking tongue, a stop block, a lever block and a lever assembly mounted thereon, the second base having a drive mechanism mounted thereon, the lever assembly including a first rotating shaft, a first lever member and a second lever member, the first lever member and the second lever member being rotatably connected to the first rotating shaft, the drive mechanism being engaged with the first lever member, the second lever member being engaged with the locking tongue, the first lever member being able to push the second lever member to rotate, and one end of the lever block being connected to the stop block.

[0005] In the above scheme, when the electric suction lock is unlocked, the outermost teeth of the bolt engage with the second actuating member. When locking, the drive mechanism drives the first actuating member to rotate, thereby pushing the second actuating member to rotate, causing the second actuating member to deflect the bolt. In this way, the bolt and the first lock mouth cooperate to form a closed state, thus realizing the locking of the electric suction lock. After the electric suction lock is in the locked state, the drive mechanism needs to drive the first actuating member to rotate and reset. In this way, when the actuating block moves the stop away from the bolt, the bolt can deflect freely to unlock, thus realizing that the electric suction lock can simultaneously satisfy electronic unlocking and mechanical unlocking.

[0006] A further preferred embodiment: the first actuating member includes a first rotating part and a first gear part, the second actuating member includes a second rotating part and a second gear part, the first gear part has a groove at one end near the first rotating part, the second rotating part is embedded in the groove, and the first rotating shaft passes through the first rotating part and the second rotating part.

[0007] In the above scheme, the first gear part is meshed with the drive mechanism, the second gear part is meshed with the locking tongue, and the second rotating part is embedded in the groove. In this way, when the first actuating member rotates to abut against the second actuating member, the first actuating member can push the second actuating member to rotate.

[0008] A further preferred embodiment: the latch is provided with a locking hook and an abutment portion, and a second locking opening is formed between the locking hook and the abutment portion, the second locking opening can cooperate with the first locking opening to achieve locking and unlocking.

[0009] In the above scheme, in the unlocked state, the first lock port and the second lock port are in the open state. When locking, the lock hook moves towards the stop block, so that the first lock port and the second lock port are in the closed state.

[0010] A further preferred embodiment: the stop block is provided with a limiting part and a third locking hole, and the abutting part can abut against the limiting part.

[0011] In the above scheme, in the locked state, the abutting part abuts against the limiting part, thereby realizing the limiting of the bolt by the stop.

[0012] A further preferred embodiment includes a lever, which is rotatably mounted on the first base, with one end of the lever embedded in the third locking slot, and a lever provided on the lever.

[0013] In the above scheme, the lever can rotate the lever block, which is embedded in the third locking hole, thus driving the stop block to rotate.

[0014] A further preferred embodiment: the first base cover is provided with a first upper cover, the first upper cover is provided with an arc-shaped hole, and the lever passes through the arc-shaped hole.

[0015] In the above scheme, the lever can move the lever along the arc-shaped hole on the first upper cover. In an emergency, the lever can be manually moved to release the limit on the lock tongue and thus open the electric suction lock.

[0016] A further preferred embodiment includes a first micro switch and a second micro switch, wherein the first micro switch is provided with a first signal connector, the second micro switch is provided with a second signal connector, and the locking device is provided with a protruding structure that can contact the first signal connector or the second signal connector.

[0017] In the above scheme, when the protruding structure contacts the first signal connector, the first micro switch can transmit a signal to the external structure electric suction lock that it is in the unlocked state; when the protruding structure contacts the second micro signal connector, the second micro switch can transmit a signal to the external structure electric suction lock that it is in the locked state.

[0018] This utility model embodiment, due to the adoption of the above technical solution, has the following advantages: It has a clever structure and can simultaneously achieve electronic and mechanical unlocking. In the unlocked state of the electric suction lock, the outermost teeth of the bolt engage with the second actuating member. When locking, the drive mechanism drives the first actuating member to rotate, thereby pushing the second actuating member to rotate, causing the second actuating member to deflect the bolt. This allows the bolt and the first lock mouth to cooperate in a closed state, thus achieving the locking of the electric suction lock. After the electric suction lock is in the locked state, the drive mechanism needs to drive the first actuating member to rotate and reset. Thus, when the actuating block is moved away from the bolt, the bolt can freely deflect to unlock, thereby enabling the electric suction lock to simultaneously satisfy both electronic and mechanical unlocking.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown in a preferred embodiment, this utility model provides a gear-driven electric suction lock, including a housing 2, a first lock opening 1 on the housing 2, a first base 21 and a second base 22, a deflectable locking tongue 3, a stop block 4, a lever block 7 and a lever assembly 5 installed on the first base 21, a drive mechanism 6 installed on the second base 22, the lever assembly 5 including a first rotating shaft 51, a first lever 52 and a second lever 53, the first lever 52 and the second lever 53 being rotatably connected to the first rotating shaft 51, the drive mechanism 6 being engaged with the first lever 52, the second lever 53 being engaged with the locking tongue 3, the first lever 52 being able to push the second lever 53 to rotate, and one end of the lever block 7 being connected to the stop block 4.

[0030] Figure 1 When the electric latch lock is in the unlocked state, the outermost teeth of the latch 3 engage with the second actuating member 53. When locking, the drive mechanism 6 drives the first actuating member 52 to rotate, thereby pushing the second actuating member 53 to rotate, causing the second actuating member 53 to deflect the latch 3. In this way, the latch 3 and the first lock jaw 1 cooperate to form a closed state. The locked state is as follows: Figure 2 As shown, in this state, if emergency unlocking is required using the lever 7, the first lever 52, the second lever 53, the bolt 3, and the drive mechanism 6 are all engaged, and the bolt 3 cannot rotate. Therefore, after locking, the drive mechanism 6 needs to drive the first lever 52 to rotate and reset, as shown. Figure 3As shown, the latch 3 is not constrained by the first actuating element 52 at this time. Thus, when the actuating block 7 is moved so that the stop block 4 moves away from the latch 3, the latch 3 can deflect freely to unlock, thereby realizing that the electric suction lock can simultaneously satisfy the functions of electronic unlocking and mechanical unlocking.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the first actuating member 52 includes a first rotating part 521 and a first gear part 522, and the second actuating member 53 includes a second rotating part 531 and a second gear part 532. The first gear part 522 has a groove 10 at one end near the first rotating part 521, and the second rotating part 531 is embedded in the groove 10. The first rotating shaft 51 passes through the first rotating part 521 and the second rotating part 531. The first gear part 522 is meshed with the drive mechanism 6, and the second gear part 532 is meshed with the locking tongue 3. The second rotating part 531 is embedded in the groove 10, so that when the first actuating member 52 rotates to abut against the second actuating member 53, the first actuating member 52 can push the second actuating member 53 to rotate.

[0032] like Figures 1 to 3 As shown, in some embodiments, the latch 3 is provided with a latch 32 and an abutment portion 33, and a second locking port 34 is formed between the latch 32 and the abutment portion 33. The second locking port 34 can cooperate with the first locking port 1 to achieve locking and unlocking. In the unlocked state, the first locking port 1 and the second locking port 34 are in the open state. When locking, the latch 32 moves towards the stop block 4, so that the first locking port 1 and the second locking port 34 are in the closed state.

[0033] In the above embodiment, when the lock is in the unlocked state, after the lock hook 32 is opened, the lock hook 32 is 1mm lower than the mating surface of the lock hook 32 to avoid the risk of interference with the lock buckle.

[0034] like Figures 1 to 3 As shown, in some embodiments, the stop 4 is provided with a limiting part 41 and a third locking port 42, and the abutting part 33 can abut against the limiting part 41. In the locked state, the abutting part 33 abuts against the limiting part 41, thereby realizing the limiting of the bolt 3 by the stop 4.

[0035] like Figures 1 to 3 As shown, in some embodiments, a lever 7 is also included. The lever 7 is rotatably mounted on the first base 21, with one end of the lever 7 embedded in the third locking slot 42. The lever 7 is provided with a lever 71. The lever 7 can be rotated by the lever 71, and since the lever 7 is embedded in the third locking slot 42, it can drive the stop block 4 to rotate.

[0036] like Figure 1 and Figure 5As shown, in some embodiments, the first base 21 is covered with a first upper cover 23, and the first upper cover has an arc-shaped hole 231 through which the lever 71 passes. The lever 71 can move the lever 7 along the arc-shaped hole 231 on the first upper cover. In an emergency, the lever 71 can be manually moved to release the restriction on the latch 3 and thus open the electric suction lock.

[0037] like Figures 1 to 4 As shown, in some embodiments, a first micro switch 8 and a second micro switch 9 are also included. The first micro switch 8 is provided with a first signal connector 81, and the second micro switch 9 is provided with a second signal connector 91. The lock is provided with a protruding structure that can contact the first signal connector 81 or the second signal connector 91. When the protruding structure contacts the first signal connector 81, the first micro switch 8 can transmit a signal indicating that the external electric lock is in the unlocked state. When the protruding structure contacts the second micro switch 9, the second micro switch 9 can transmit a signal indicating that the external electric lock is in the locked state.

[0038] In the above embodiments, it can be seen that when the protruding structure contacts the second micro-motion signal connector, the first bevel tooth 51 and the second bevel tooth 52 mesh and connect, thereby ensuring that the full lock signal feedback and the mechanical full locking position are synchronized.

[0039] This utility model discloses the working principle and process of a gear-driven electric suction lock. When the electric suction lock is in the unlocked state, the outermost teeth of the latch 3 engage with the second actuating member 53. When locking, the drive mechanism 6 drives the first actuating member 52 to rotate, thereby pushing the second actuating member 53 to rotate, causing the second actuating member 53 to deflect the latch 3. In this way, the latch 3 and the first lock opening 1 cooperate to form a closed state. In this state, if it is necessary to use the lever 7 for emergency unlocking, the first actuating member 52, the second actuating member 53, the latch 3 and the drive mechanism 6 are all engaged, and the latch 3 cannot rotate. Therefore, after locking, the drive mechanism 6 needs to drive the first actuating member 52 to rotate and reset. At this time, the latch 3 is not constrained by the first actuating member 52. Thus, when the lever 7 is moved to make the stop 4 move away from the latch 3, the latch 3 can deflect freely to unlock.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
