[0028] The embodiments of the present invention 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 invention, and are not to be construed as limitations on the present invention. In the description of the present invention, 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 invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0029] See also Figure 1-12 The utility model provides an embodiment: a flip-bolt electronic lock body, comprising a shell 1, a lock tongue assembly 6 is provided inside the shell 1, and the lower part of the lock tongue assembly 6 is slidably matched with a brake pin 61; a lock core assembly 2 is also provided in the middle of the shell 1; wherein, the lock core assembly 2 is linked to the brake pin 61 through a toggle member 5, and the upper part of the lock core assembly 2 is linked to a driving member 3; an electric control mechanism 4 is also provided in the shell 1, and the electric control mechanism 4 is located below the shell 1.

[0030] To sum up, the driving member 3, lock core assembly 4, toggle member 5, lock tongue assembly 6 and other components are integrated inside the shell 1. Firstly, the various components inside the shell 1 are more compact and the layout is more reasonable; secondly, the driving member 3 is connected to the toggle member 5 through the lock core assembly 2, and is connected to the lock tongue assembly 6 through the toggle member 5, so that both manual unlocking and electric unlocking can be achieved while limiting the flipping of the lock tongue; thirdly, the electronic control mechanism 4 can accurately obtain the position of the second paddle to improve the control accuracy of the equipment.

[0031] Specifically, the lock cylinder assembly 2 includes a first paddle 20 that is linked to the lock cylinder, with a second paddle 23 disposed below the first paddle 20. The first paddle 20 or the second paddle 23 causes the toggle member 5 to rotate within the housing 1, thereby releasing the locking action of the brake pin 61 on the lock tongue 66. The lock tongue assembly 6 includes a bracket 63 and a lock tongue 66 that slides within the bracket 63. A retaining groove 65 is disposed on the side of the lock tongue 66, and one end of the brake pin 61 is inserted into the retaining groove 65 to prevent the lock tongue 66 from turning over.

[0032] In summary, since the second paddle 23 is linked to 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 retaining groove 65, thereby completing 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 from the retaining groove 65, thereby completing manual unlocking. Based on this, the problem of the device being difficult to unlock after power failure can be effectively solved.

[0033] 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. This can simplify the locking structure of the lock tongue 66 and enhance the locking ability of the lock tongue 66. Therefore, while further locking the lock tongue 66, the locking structure is simple and uncomplicated, thereby further improving the anti-theft ability and security of the lock.

[0034] To ensure that the lock tongue 66 can be smoothly reset, the lock tongue assembly 6 also includes a fixing frame 60 sleeved on the outside of 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 reset of the lock tongue 66, 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.

[0035] To ensure smooth separation of the brake pin 61 from the retaining groove 65, the driving member 3 includes a housing 30, within which is housed a motor 33 and a reduction gear set 32. The reduction gear set 32 ​​meshes with the teeth 24 on the second paddle 23, causing the second paddle 23 to rotate within the housing 1. Specifically, the reduction gear set 32 ​​includes a worm 31 mounted on the output shaft of the motor 33. The worm 31 meshes with a worm wheel 34, which in turn meshes with a second gear 35. The second gear 35 meshes with a third gear 36, which in turn meshes with the teeth 24 via an output gear 37. Through this mechanism, the gear transmission drives the toggle member 5 to rotate, thereby smoothly disengaging the brake pin 61 from the retaining groove 65. The reduction gear set 32 ​​also increases torque, enabling the brake pin 61 to quickly and reliably separate from the retaining groove 65 when the motor 33 is energized.

[0036] In addition, the arrangement of the reduction gear set 32 ​​can increase the output torque of the motor 33 while reducing the power consumption of the motor 33 .

[0037] 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 to the first paddle 20, and the other end of the torsion spring 22 is fixed in the housing 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.

[0038] Furthermore, since the housing 1 further includes an electric control mechanism 4 comprising a housing 40, and a detection member 42 is provided on the housing 40, the rotational position of the second paddle 23 is detected by the detection member 42. Therefore, the rotational position of the second paddle 23 can be detected in real time by the detection member 42, thereby facilitating the detection member 42 to cut off the circuit of the motor 33, thereby stopping the motor 33; the detection member 42 is preferably a circuit board.

[0039] Specifically, the detection member 42 is integrated with a first probe 41 and a second probe 44. The second paddle 23 is moved between the first and second probes 41, 44 by the trigger 21, enabling the detection member 42 to obtain position information of the second paddle 23. Therefore, when the trigger 21 moves into the first probe 41 or into the second probe 44, the detection member 42 obtains this information and then disconnects the circuit of the motor 33. This prevents excessive rotation of the motor 33, which could cause the paddle 5 to break, or the brake pin 61 to completely separate from the mounting bracket 60, potentially causing the lock to malfunction.

[0040] In addition, since the box body 40 is further 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.

[0041] To ensure that the toggle member 5 can smoothly and reliably transmit power from the driver 3 to the brake pin 61, the toggle member 5 includes a pin holder 50 connected to the housing 1. One end of the pin holder 50 contacts the brake pin 61 via a shift block 51, and the other end of the pin holder 50 is linked to the lock cylinder assembly 2 via a linkage block 52. Therefore, the toggle member 5 rotates on the pin rod inside the housing 1 via the pin holder 50, thereby utilizing the principle of leverage to cause the brake pin 61 to separate from the retaining groove 65. The shift block 51 is shorter than the linkage block 52, thereby reducing the output power of the motor 33, thereby reducing both the size of the motor 33 and the power consumption of the motor 33.

[0042] At the same time, the upper surface of the linkage block 52 contacts the first paddle 20 via a first protrusion 53, and the lower surface of the linkage block 52 contacts the second paddle 23 via a second protrusion 54. Therefore, the two staggered protrusions, one, ensure reliable power transmission between the toggle member 5 and the two paddles; two, reduce the overall height of the lock cylinder assembly 2 to optimize the internal space of the housing 1; and three, allow the first paddle 20 and the second paddle 23 to contact the toggle member 5 in separate spaces, avoiding interference while improving the reliability of the two paddles and the toggle member 5.

[0043] 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. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
