As shown in fig. 1 to 3, an electronic lock provided in an embodiment of the present application will now be described. The electronic lock comprises a shell 10, a control panel 20, a driving mechanism 30, a transmission mechanism 40, an output mechanism 50 and a limiting mechanism 70.

As shown in fig. 4, the interior of the housing 10 has a cavity 101, and the cavity 101 is used for mounting and fixing the internal components of the electronic lock. The housing 10 is provided with a stopper 11 inside. In practical applications, the housing 10 may be designed into any reasonable shape as desired. To facilitate mounting of the internal components and manufacturing, the housing 10 comprises a first and a second housing which are close together, between which said cavity 101 is formed. A side surface of the housing 10 is provided with a locking hole 102.

The control board 20 is a control mechanism of the entire electronic lock, and the control board 20 is installed in the cavity 101 of the housing 10.

The driving mechanism 30 is installed in the cavity 101 of the housing 10 and electrically connected to the control board 20, so that the control board 20 controls the operation and stop of the driving mechanism 30. Alternatively, the driving mechanism 30 is a motor, and the driving mechanism 30 is connected to the control board 20 through a terminal wire or an FPC (Flexible Printed Circuit), thereby providing power.

The transmission mechanism 40 is mounted in the cavity 101 of the housing 10. The transmission mechanism 40 is connected to the output of the drive mechanism 30. Alternatively, the transmission mechanism 40 is a gear assembly, for example, in the present embodiment, the transmission mechanism 40 is a parallel shaft gear assembly. The transmission mechanism 40 is a single-stage or multi-stage transmission mechanism, and in practical application, can be flexibly designed according to the actual situation of the electronic lock. For example, in the present embodiment, the transmission mechanism 40 is a multi-stage gear transmission, and the last stage gear of the transmission mechanism 40 can be flexibly designed according to the working requirement of the output mechanism 50. Alternatively, the last gear of the transmission 40 is a 0-360 ° sector gear.

The output mechanism 50 is installed in the cavity 101 of the housing 10, and the output mechanism 50 is connected to the transmission mechanism 40, so that the transmission mechanism 40 drives the output mechanism 50 to move, and locking or unlocking is achieved. In other words, the driving mechanism 30, the transmission mechanism 40 and the output mechanism 50 are connected in sequence, wherein the input end of the transmission mechanism 40 is connected with the driving mechanism 30, and the output end of the transmission mechanism 40 is connected with the output mechanism 50, so that the driving mechanism 30 finally drives the output mechanism 50 to operate through one-stage or multi-stage transmission, and the effects of speed reduction and force increase are achieved.

The limiting mechanism 70 includes a limiting member 71 and an electronic switch 72, and the limiting member 71 is connected to the transmission mechanism 40 or the output mechanism 50 and moves correspondingly with the transmission mechanism 40 or the output mechanism 50. The stopper 71 has an electronic stopper 711 and a mechanical stopper 712. The electronic switch 72 is electrically connected to the control board 20. The electronic switch 72 is disposed at a position that can be triggered by the movement of the electronic stopper 711 to feed back the automatic locking or unlocking position. Specifically, when the limiting member 71 moves along with the transmission mechanism 40 or the output mechanism 50, the electronic limiting portion 711 of the limiting member 71 triggers the electronic switch 72, so that the electronic switch 72 feeds back an automatic locking or unlocking signal to the control board 20, and the control board 20 controls the driving mechanism 30 to stop operating accordingly after receiving the automatic locking or unlocking signal. The electronic limit part 711 of the limit member 71 is engaged with the electronic switch 72, thereby realizing automatic locking or unlocking position feedback.

On the other hand, the mechanical stopper 712 is disposed at a position where it can contact the stopper 11 of the housing 10 when the stopper 71 moves, to stop the operation of the driving mechanism 30. Specifically, when the electronic switch 72 is suddenly powered off or fails, along with the movement of the limiting member 71, when the electronic limiting portion 711 moves to a position originally scheduled to trigger the electronic switch 72, the electronic switch 72 cannot feed back a signal to the control board 20 to stop the operation of the driving mechanism 30, and at this time, the mechanical limiting portion 712 contacts and is cooperatively clamped with the limiting portion 11 of the housing 10, so as to mechanically block the driving mechanism 30, thereby locking or unlocking the driving mechanism.

The working process of the electronic lock is as follows: the driving mechanism 30 drives the transmission mechanism 40, and the output mechanism 50 performs telescopic action and is matched with the lock hole 102 of the electronic lock to realize locking and unlocking actions through the transmission of the transmission mechanism 40; meanwhile, the limiting member 71 rotates along with the transmission mechanism 40 or the output mechanism 50, and when the limiting member 71 rotates until the electronic limiting portion 711 touches the electronic switch 72, the electronic switch 72 transmits a signal to the control board 20, so that the control board 20 controls the driving mechanism 30 to stop working. When the electronic switch 72 fails due to power failure or malfunction, the limiting member 71 rotates until the mechanical limiting portion 712 contacts the limiting portion 11 of the housing 10 to achieve mechanical braking, the driving mechanism 30 is blocked, and locking or unlocking is completed.

Compared with the prior art, the electronic lock provided by the application is provided with the limiting mechanism 70, and the limiting piece 71 of the limiting mechanism 70 is provided with the electronic limiting part 711 and the mechanical limiting part 712, so that when the driving mechanism 30, the transmission mechanism 40 and the output mechanism 50 are used for automatic locking or unlocking, the electronic limiting part 711 triggers the electronic switch 72 to feed back an automatic locking or unlocking position signal, and further the control board 20 controls the driving mechanism 30 to stop; when the electronic switch 72 fails, the mechanical limiting part 712 can contact the position of the limiting part 11 of the housing 10 during the movement of the transmission mechanism 40 or the output mechanism 50, and the mechanical limiting part 712 and the limiting part 11 of the housing 10 cooperate to block the driving mechanism 30, thereby realizing braking. The electronic lock has the advantages that the position feedback can be realized in the automatic locking or unlocking state of the electronic lock by arranging the limiting piece 71 which is provided with the electronic limiting part 711 and the mechanical limiting part 712; and the electronic limiting part 711 and the mechanical limiting part 712 are integrated on the limiting part 71, so that two sets of limiting mechanisms are not needed, a double-protection effect can be achieved, electronic and mechanical limiting is realized, the structure is simplified, and the reliability and the stability of the product are improved.

In another embodiment of the present application, as shown in FIG. 6, the position-limiting member 71 has two spaced apart electrical position-limiting portions 711 and two spaced apart mechanical position-limiting portions 712. The two electrical stoppers 711 correspond to the locked position or the unlocked position, and the two mechanical stoppers 712 also correspond to the locked position or the unlocked position. Thus, during locking, one of the electronic limiting parts 711 triggers the electronic switch 72 to stop the driving mechanism 30 and feed back the locking position; when unlocking, the other electronic limit part 711 triggers the electronic switch 72 to stop the driving mechanism 30 and feed back the unlocking position. Similarly, when the electronic limit mode fails, the two mechanical limit parts 712 respectively contact and cooperate with the limit part 11 of the housing 10, so as to block the driving mechanism 30, thereby realizing locking or unlocking. The two electronic limiting parts 711 and the two mechanical limiting parts 712 are integrated on the limiting part 71, so that a double protection effect can be achieved, and the reliability and the stability of the product are improved.

Further, the mechanical stopper portion 712 is at a position later in the movement stroke than the electrical stopper portion 711, and a hysteresis virtual bit exists therebetween, as shown by the H position in fig. 6. When the electronic switch 72 is suddenly powered off or fails, along with the movement of the limiting member 71, when the electronic limiting portion 711 moves to the position originally scheduled to trigger the electronic switch 72, the electronic switch 72 cannot feed back a signal to the control board 20 to stop the operation of the driving mechanism 30, and at this time, the limiting member 71 will continue to move until the mechanical limiting portion 712 located at a more lagging position of the movement stroke contacts and is matched with and clamped with the limiting portion 11 of the housing 10, so as to mechanically block the driving mechanism 30, thereby achieving locking or unlocking.

It will be appreciated that the mechanical limiting part 712 is disposed at a position lagging behind the electrical limiting part 711, which ensures that the electrical limiting part 711 performs a limiting function during the movement of the limiting member 71, i.e., the mechanical limiting part 712 does not function when the electrical limiting part 711 performs a limiting function. The mechanical stopper 712 functions only when the electronic stopper fails in an unexpected situation such as a power failure or a failure of the drive mechanism 30 or the electronic switch 72. The purpose of designing the hysteresis dummy bit of the mechanical limiting portion 712 is to avoid the mechanical limiting portion 712 from performing a limiting function earlier than the electrical limiting portion 711 during a transmission process due to transmission errors or other errors, thereby causing a braking advance.

In another embodiment of the present application, as shown in fig. 6, the limiting element 71 is an annular body, and a center of the limiting element 71 is limited by a D-shaped hole and sleeved on the transmission shaft of the last stage of the transmission mechanism 40 and rotates with the transmission mechanism 40. The outer edge of the position-limiting member 71 has two first blocking edges on the same circumference and two second blocking edges on the other circumference, the two first blocking edges correspond to the two electronic position-limiting portions 711, and the two second blocking edges correspond to the two mechanical position-limiting portions 712. As can be seen from fig. 6, the two first blocking edges and the two second blocking edges are not located on the same plane, so that the first blocking edge serving as the electronic limiting part 711 and the second blocking edge serving as the mechanical limiting part 712 can be spatially offset without interference. When the lock is locked, the limiting member 71 rotates along with the transmission shaft to one of the electronic limiting parts 711 to trigger the electronic switch 72, so as to stop the driving mechanism 30 and feed back the locking position; when unlocking, the limiting member 71 reversely rotates along with the transmission shaft to another electronic limiting portion 711 to trigger the electronic switch 72, so as to stop the driving mechanism 30 and feed back the unlocking position. When the electronic limiting mode fails, the limiting member 71 rotates to a position where the electronic limiting portion 711 triggers the electronic switch 72, and the driving mechanism 30 does not stop operating, so the limiting member 71 continues to rotate until the mechanical limiting portion 712 and the limiting portion 11 of the housing 10 are clamped in contact, thereby blocking the driving mechanism 30, realizing locking or unlocking, and feeding back the locking or unlocking position.

It will be appreciated by those skilled in the art that the shape and structure of the limiting member 71 are not limited to the ring-shaped body, and other reasonable shapes of the limiting member 71 may be adopted in other embodiments. The limiting member 71 may be connected to the output mechanism 50 and move along with the output mechanism 50, as long as the positions of the electronic switch 72 and the limiting portion 11 are adjusted accordingly, so that the limiting and feedback locking/unlocking positions can be achieved.

In another embodiment of the present application, the electronic switch 72 is a micro switch, the electronic limit part 711 and the micro switch touch to realize electronic limit and position feedback, and the mechanical limit part 712 and the limit part 11 of the housing 10 contact to realize mechanical limit and position feedback. Electronic switch 72 sets up on control panel 20, and control panel 20 and actuating mechanism 30's axis parallel arrangement integrates electronic switch 72 on control panel 20 like this, can save space, under the unchangeable prerequisite of the whole overall dimension of assurance product, can provide the space for actuating mechanism 30 that has bigger output to finally realize bigger output.

In another embodiment of the present application, referring to fig. 1, fig. 3 and fig. 5, the electronic lock further includes an emergency mechanism 60, where the emergency mechanism 60 is connected to the transmission mechanism 40, so that the emergency mechanism 60 sequentially drives the transmission mechanism 40 and the output mechanism 50 to implement emergency locking or unlocking. In other words, the emergency mechanism 60 can likewise move the output mechanism 50 via the transmission mechanism 40, and finally the locking or unlocking is effected. The electronic lock has two locking and unlocking modes, one mode is that the driving mechanism 30 drives the transmission mechanism 40 and the output mechanism 50 to operate so as to realize automatic locking and unlocking, and the other mode is that the emergency mechanism 60 is manually operated to drive the transmission mechanism 40 and the output mechanism 50 to operate so as to realize emergency locking and unlocking. Therefore, when the electronic lock is suddenly powered off or accidents such as sudden failure of the driving mechanism 30 occur, the electronic lock may be in a state that the electronic lock is locked and cannot be unlocked, and the user can also manually operate the emergency mechanism 60 to perform emergency locking and unlocking, so that the electronic lock is prevented from being locked due to sudden accidents. When emergency locking or unlocking is required, a user manually operates the emergency mechanism 60, and drives the transmission mechanism 40 and the output mechanism 50 to move in a manner of manually inputting power, so that the output mechanism 50 makes telescopic action and is matched with the lock hole 102 of the electronic lock, and the emergency locking or unlocking action is realized; at the same time, the limiting member 71 of the limiting mechanism 70 will also move along with the transmission mechanism 40 or the output mechanism 50, and when the electronic limiting portion 711 of the limiting member 71 moves to the position originally scheduled to trigger the electronic switch 72, because the driving mechanism 30 is disabled, the electronic limiting mode will not work, and the limiting member 71 will rotate until any one of the mechanical limiting portions 712 contacts and is matched with and clamped to the limiting portion 11 of the housing 10, thereby completing locking or unlocking.

Specifically, the emergency mechanism 60 includes an input end 61 and a transmission end 62 connected in sequence, and the input end 61 is exposed out of the housing 10, thereby facilitating the manual power input of the user. The user can operate the input 61 to perform emergency locking or unlocking when an accident such as power failure or malfunction occurs in the drive mechanism 30. The transmission end 62 is connected with the transmission mechanism 40, so that the output mechanism 50 can be driven by the input end 62, the transmission end 62 and the transmission mechanism 40 in sequence to realize emergency locking or unlocking; the input end 61 is also coupled to the driving mechanism 30, that is, when the driving mechanism 30 drives the output mechanism 50 through the transmission mechanism 40, the driving mechanism 30 can also drive the input end 61 to rotate through the transmission mechanism 40 and the transmission end 62.

In another embodiment of the present application, as shown in fig. 1, 3 and 5, the input end 61 is a rotating handle, the transmission end 62 includes a transmission shaft and a transmission gear sleeved together, the rotating handle is connected with the transmission shaft, and the transmission gear of the transmission end 62 rotates along with the transmission shaft to transmit power. The drive gear of the drive end 62 is in meshing engagement with the drive gear of the drive mechanism 40. When the transmission mechanism 40 is a multi-stage gear transmission, the transmission gear of the transmission end 62 can be meshed with any stage gear of the transmission mechanism 40 for transmission.

Alternatively, the position limiting portion 11 of the housing 10 is a protrusion or a boss formed in the housing 10.

In another embodiment of the present application, referring to fig. 1, 4 and 5, the housing 10 has a first guiding portion 12. The output mechanism 50 includes a connecting portion 51, a second guide portion 52, and an output portion 53 connected in this order. Wherein the connecting part 51 is connected with the transmission mechanism 40, and when the transmission mechanism 40 is a multi-stage transmission mechanism, the connecting part 51 is connected with the transmission member of the last stage. The first guide portion 12 and the second guide portion 12 cooperate, thus serving as a guide. The various components of the output mechanism 50 are fixedly connected or integrally disposed.

Alternatively, the connecting portion 51 is a rack. The rack gear is engaged with the pinion gear of the gear mechanism 40.

Alternatively, the first guide portion 12 is a groove or a protrusion formed in the housing 10; correspondingly, the second guiding portion 52 is a protrusion or a groove.

Optionally, the output 53 is a key cylinder. For example, in the present embodiment, the output portion 53 has a long shaft shape or a wedge shape. The output portion 53 is located at a position corresponding to the locking hole 102 and is operable to perform telescopic movement.

The application provides an electronic lock has following advantage: firstly, the limiting piece 71 which is simultaneously provided with the electronic limiting part 711 and the mechanical limiting part 712 is adopted, so that the dual-limiting protection effect can be achieved, the electronic limiting and the mechanical limiting are realized, and the reliability and the stability of the product are improved; secondly, the electronic lock can be automatically locked or unlocked, and by arranging the emergency mechanism 60, manual emergency locking and unlocking can be realized under unexpected conditions such as sudden power failure or faults, so that the situation that the electronic lock is accidentally locked is avoided, and the reliability of the product is improved; thirdly, a lag virtual position is arranged between the mechanical limiting part 712 and the electronic limiting part 711 in the limiting part 71, so that the braking advance caused by transmission errors is effectively avoided; the mechanical limiting part 712 in the limiting part 71 not only plays a role of protection in the automatic locking and unlocking process, but also realizes a mechanical braking function in the manual emergency locking and unlocking process; fourthly, due to the limitation of the space in the vehicle, the electronic lock is required to occupy a small enough space, so that the traditional electronic lock in the market has a small lock rod stroke, and the reliability and the stability of the traditional electronic lock cannot be ensured; the electronic lock of the present application integrates the electronic switch 72 on the control board 20, and the axes of the control board 20 and the driving mechanism 30 are arranged in parallel, so that compared with other arrangement modes of the control board 20 and the electronic switch 72, the electronic lock of the present application can save space and provide space for longer stroke required by the driving mechanism 30 and the lock rod with larger output force.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
