[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0018] like Figures 1 to 3 As shown, an electronic lock with a top and bottom lock tongue comprises a central control housing 1, and oblique tongue housings 2 respectively arranged at the upper and lower ends of a door leaf, wherein an oblique tongue 21 and a connecting column 20 capable of driving the oblique tongue 21 are arranged on the oblique tongue housing 2, and a reset spring 25 is arranged in the oblique tongue housing 2 to press the oblique tongue 21 to reset and pop out, and the connecting column 20 is inserted into the central control housing 1, and two oblique tongue housings 2 are respectively arranged at the upper and lower ends of the door leaf, and the oblique tongue extends into the oblique tongue hole of the door frame to lock the door leaf. The central control housing 1 is provided with a first electric drive block 3 with one end capable of driving the connecting column 20 at the upper end, a second electric drive block 4 capable of driving the connecting column 20 at the lower end, and an electric drive device 5 capable of driving the first electric drive block 3 and the second electric drive block 4 to drive the oblique tongue 21 respectively. The first electric drive block 3 and the second electric drive block 4 move up and down in the oblique tongue housing 2. When opening the door, the first electric drive block 3 and the second electric drive block 4 both move into the central control housing 1. The central control housing 1 is also provided with a manual drive device capable of being manually moved to drive the connecting columns 20 at the upper and lower ends. If the electric drive device 5 fails or the power is cut off, it can be opened by the manual drive device. The manual drive device is fixedly connected to the connecting column 20. When the electric drive device 5 drives the first electric drive block 3 and the second electric drive block 4, it drives the manual drive device to pull the connecting column 20 to retract the oblique tongue 21.

[0019] The manual driving device includes a first manual driving block 61 that can drive the inclined tongue 21 at the upper end, a second manual driving block 62 that can drive the inclined tongue 21 at the lower end, and a linkage block 63 that can be driven by the first manual driving block 61 to drive the second manual driving block 62. A shift lever 64 extending outside the central control housing 1 is provided on the second manual driving block 62. The linkage block 63 moves the first manual driving block 61 and the second manual driving block 62 together, so as to simultaneously pull the inclined tongue 21 back into the inclined tongue housing 2. The first manual driving block 61 and the second manual driving block 62 are relatively spaced-apart racks, and the linkage block 63 is a linkage gear meshing with the first manual driving block 61 and the second manual driving block 62. The rack portions of the first manual driving block 61 and the second manual driving block 62 are relatively spaced apart, and the linkage gear is between the two rack portions.

[0020] At one end of the first electric driving block 3 and the second electric driving block 4 close to the inclined tongue housing 2, first connection heads 34 are respectively provided. A first insertion hole 35 is provided on the first connection head 34. Second connection heads 65 are provided on the first manual driving block 61 and the second manual driving block 62. The second connection head 65 on the first manual driving block 61 can abut against the first connection head 34 on the first electric driving block 3. A second insertion hole 66 is provided on the second connection head 65. The second connection head 65 on the second manual driving block 62 can abut against the first connection head 34 on the second electric driving block 4. The first connection head 34 is close to the inclined tongue housing 2, and the second connection head 65 is relatively far from the inclined tongue housing 2. One end of the connecting column 20 passes through the first insertion hole 35 and is fixed to the second insertion hole 66. The connecting column 20 can axially move relative to the first insertion hole 35. In this way, when the electric control part is started, the first electric driving block 3 and the second electric driving block 4 will respectively drive the first manual driving block 61 and the second manual driving block 62 to drive the inclined tongue 21, and when the manual part is started, it will not abut against the first manual driving block 61 and the second manual driving block 62. Therefore, the mechanical and electrical separation during manual opening is achieved.

[0021] The first electric driving block 3 and the first manual driving block 61 are stacked, and the second electric driving block 4 and the second manual driving block 62 are stacked. Four guiding holes 11 are provided on the central control housing 1. Guiding columns 12 that can be inserted into the guiding holes 11 one by one are respectively provided on the first electric driving block 3, the first manual driving block 61, the second electric driving block 4, and the second manual driving block 62. The guiding holes 11 extend towards the inclined tongue housing 2 at the upper and lower ends.

[0022] The first electric driving block 3 and the second electric driving block 4 are relatively spaced-apart racks. The electric driving device 5 includes a motor 51 and a driving gear 52 driven by the motor 51. The driving gear 52 meshes with the first electric driving block 3 and the second electric driving block 4. The driving gear 52 is provided between the first electric driving block 3 and the second electric driving block 4 and meshes with the rack portions of the first electric driving block 3 and the second electric driving block 4 at the same time.

[0023] A locking tongue rod 23 is provided on the inclined tongue 21. A sliding frame 22 capable of sliding on the inclined tongue housing 2 and driving the locking tongue rod 23 is provided inside the inclined tongue housing 2. The locking tongue rod 23 is inserted into the sliding frame 22 in a relatively slidable manner, and when the inclined tongue 21 is squeezed, the locking tongue rod 23 slides relative to the sliding frame 22. In this way, when closing the door, the inclined tongue 21 can be squeezed and retracted into the inclined tongue housing 1. An insertion block 24 is provided on the sliding frame 22. A connecting column 20 is provided on the insertion block 24 and one end thereof extends out of the inclined tongue housing 2. A return spring 25 capable of elastically pressing the inclined tongue 21 to reset is provided between the sliding frame 22 and the inclined tongue 21. The sliding frame 22 can drive the locking tongue rod 23 to retract into the inclined tongue housing 2. A chute 26 extending along the length direction of the inclined tongue housing 2 is provided on the inclined tongue housing 2. A sliding block 27 capable of sliding in the chute 26 is provided on the sliding frame 22. The return spring 25 is sleeved on the locking tongue rod 23. One end of the return spring 25 abuts against the sliding block 27, and the other end abuts against the inclined tongue 21. A connecting wall 28 is provided on the sliding frame 22. A mounting hole 30 for the locking tongue rod 23 to pass through is provided on the connecting wall 28. A positioning block 29 capable of pressing against the connecting wall 28 is provided at one end of the locking tongue rod 23 passing through the mounting hole 30. The sliding frame 22 is U-shaped. One end of the locking tongue rod 23 penetrates into the U-shape. The positioning block 29 can press against the inner wall inside the U-shape. In this way, after the positioning block 29 presses against the connecting wall 28, the locking tongue rod 23 can move into the U-shape, but cannot be pulled out of the U-shape.
