DETAILED DESCRIPTION
[0029] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.
[0030] See also Figure 1-12 The utility model provides an embodiment: an electronic lock, comprising a housing 1, a lock core assembly 2 installed inside the housing 1, and a lock tongue assembly 6 linked to the lock core assembly 2; the lock core assembly 2 comprises a first paddle 20, and a second paddle 23 is further provided below the first paddle 20; one end of the second paddle 23 is linked to a driving member 3, and the second paddle 23 and the end of the first paddle 20 away from the driving member 3 are both connected to a toggle member 5 provided inside the housing 1; the lock tongue assembly 6 comprises a lock tongue 66 A brake pin 61 for limiting the flipping of the lock tongue 66 and a stop groove 65 arranged on the side of the lock tongue 66, the brake pin 61 cooperates with the stop groove 65 to prevent the lock tongue 66 from flipping, so as to complete the locking of the lock tongue 66 by the brake pin 62; when the driving member 3 is used to cause the second paddle 23 to rotate, the toggle member 5 is driven to rotate inside the shell 1, so that the other end of the toggle member 5 causes the brake pin 61 to separate from the stop groove 65, so as to release the lock of the lock tongue 66 by the brake pin 61.
[0031] In summary, since the second paddle 23 is linked with the driving member 3, the driving member 3 can cause the second paddle 23 to drive the toggle member 5 to separate the brake pin 61 from the stop groove 65, thereby completing the electronic unlocking; at the same time, the first paddle 20 can also be used to cause the toggle member 5 to drive the brake pin 61 to separate from the stop groove 65, thereby completing the manual unlocking; based on this, the problem that the device is difficult to unlock after power failure can be effectively solved;
[0032] Furthermore, the brake pin 61 cooperates with the stop groove 65 to prevent the lock tongue 66 from sliding into the interior of the shell 1, thereby completing the locking of the lock tongue 66. The locking structure of the lock tongue 66 can be simplified, and the locking ability of the lock tongue 66 can also be enhanced. Therefore, the locking structure is simple and uncomplicated while the lock tongue 66 is further locked, thereby further improving the anti-theft ability and safety of the lock.
[0033] In order to ensure that the lock tongue 66 can be smoothly reset, the lock tongue assembly 6 further includes a bracket 63 and a fixing frame 60 sleeved outside the bracket 63, and the lock tongue 66 contacts the fixing frame 60 through a spring 64, and the brake pin 61 is connected to the fixing frame 60 through a tension spring 62. Therefore, the spring 64 can be used to promote the lock tongue 66 to reset, and the spring 64 is compressed when the door is opened, which facilitates the lock tongue 66 to slide inward and also facilitates the lock tongue 66 to flip.
[0034] In order to ensure that the brake pin 61 and the stop groove 65 can be separated smoothly, the driving member 3 includes a housing 30, and a motor 33 and a reduction gear set 32 are arranged in the housing 30; and the reduction gear set 32 is meshed with the teeth 24 on the second paddle 23 to promote the second paddle 23 to rotate in the housing 1. Specifically, the reduction gear set 32 includes a worm 31 installed on the output shaft of the motor 33, the worm 31 is meshed with a worm wheel 34, and the worm wheel 34 is meshed with a second gear 35, and the second gear 35 is meshed with a third gear 36, and the third gear 36 is meshed with the teeth 24 through an output gear 37. In the above manner, the gear transmission is used to promote the rotation of the toggle member 5, thereby driving the brake pin 61 to be separated from the stop groove 65 smoothly; and the reduction gear set 32 can also increase the torque, so that when the motor 33 is powered on, the brake pin 61 can be quickly and reliably separated from the stop groove 65.
[0035] In addition, the setting of the reduction gear set 32 can increase the output torque of the motor 33 and reduce the power consumption of the motor 33 at the same time.
[0036] Furthermore, since a torsion spring 22 is provided between the first paddle 20 and the second paddle 23, wherein one end of the torsion spring 22 is fixed on the first paddle 20, and the other end of the torsion spring 22 is fixed in the shell 1, the torsion spring 22 can be used to cause the first paddle 20 to rotate and then reset, so that the user can complete the separation of the brake pin 61 and the retaining groove 65 through a mechanical structure such as a door handle.
[0037] In addition, since the housing 1 is further provided with an electric control mechanism 4, and the electric control mechanism 4 includes a box body 40, and a detection member 42 is provided on the box body 40, and the detection member 42 is used to obtain the rotation position of the second paddle 23. Therefore, the detection member 42 can be used to obtain the rotation position of the second paddle 23 in real time, so that the detection member 42 can cut off the circuit of the motor 33 to stop the motor 33 from working; wherein the detection member 42 is preferably a circuit board.
[0038] Specifically, the detection member 42 is integrated with a first probe 41 and a second probe 44, and the second paddle 23 passes through the provided trigger portion 21 and moves between the first probe 41 and the second probe 44 through the trigger portion 21, so that the detection member 42 obtains the position information of the second paddle 23. Based on this, when the trigger portion 21 moves into the first probe 41 or moves to the second probe 44, the detection member 42 obtains the above information and cuts off the circuit of the motor 33 to prevent the motor 33 from rotating excessively and causing the toggle member 5 to be twisted off, or causing the brake pin 61 to completely fall off from the fixing frame 60, which causes the lock to not work properly.
[0039] In addition, since the box body 40 is also provided with a display element 43, and the battery power information is displayed through the display screen on the display element 43, it is convenient for the user to understand the battery power inside the box body 40 from the outside.
[0040] In order to ensure that the toggle member 5 can smoothly and reliably transmit the power from the driving member 3 to the brake pin 61, the toggle member 5 includes a shaft pin seat 50 connected to the housing 1, one end of the shaft pin seat 50 contacts the brake pin 61 through a set of toggle blocks 51, and the other end of the shaft pin seat 50 is linked with the lock cylinder assembly 2 through a set of linkage blocks 52. Therefore, the toggle member 5 rotates on the shaft pin rod inside the housing 1 through the shaft pin seat 50, and then the brake pin 61 can be separated from the stop groove 65 by using the lever principle; wherein, the length of the toggle block 51 is less than the length of the linkage block 52, so the output power of the motor 33 can be reduced, firstly, the volume of the motor 33 can be reduced; secondly, the power consumption of the motor 33 can be reduced.
[0041] At the same time, the upper surface of the linkage block 52 contacts the first paddle 20 through the first protrusion 53, and the lower surface of the linkage block 52 contacts the second paddle 23 through the second protrusion 54. Therefore, the two staggered protrusions, firstly, enable reliable transmission of power between the toggle member 5 and the two paddles; secondly, reduce the overall height of the lock cylinder assembly 2 to optimize the internal space of the housing 1; thirdly, enable the first paddle 20 and the second paddle 23 to contact the toggle member 5 in their own independent spaces, avoiding interference while improving the reliability of the two paddles and the toggle member 5 when working.
[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
