[0039] The following further elaborates on the embodiments of the present utility model with reference to the accompanying drawings.

[0040] According to some embodiments of the present utility model, referring to Figures 1 to 4 , the electronic door lock device includes a lock body 100 and a lock catch 400. A driving component 110, a speed reduction component 200, and a lock rod component 300 are provided inside the lock body 100. A lock hole 101 communicating with the inner cavity of the lock body 100 is provided on the upper side wall of the lock body 100. The output end of the driving component 110 is connected to the input end of the speed reduction component 200, and the output end of the speed reduction component 200 is connected to the lock rod component 300. The driving component 110 can drive the lock rod component 300 to move to a first position or a second position. The lock catch 400 is located above the lock body 100. The lock catch 400 is connected with a lock tongue 410, and a lock groove 420 is provided on the lock tongue 410. The lock catch 400 can move relative to the lock body 100 in the up and down direction, so that the lock tongue 410 is inserted into the lock body 100 through the lock hole 101.

[0041] When the lock tongue 410 is inserted into the lock body 100 and the driving component 110 drives the lock rod component 300 to move to the first position, the lock rod component 300 is inserted into the lock groove 420, and the lock rod component 300 restricts the lock tongue 410 from moving in the up and down direction, and the lock body 100 and the lock catch 400 are relatively fixed.

[0042] When unlocking is required, the driving component 110 drives the lock rod component 300 to move from the first position to the second position, the lock rod component 300 disengages from the lock groove 420, and the lock catch 400 can move relative to the lock body 100 in the up and down direction so that the lock tongue 410 disengages from the lock body 100.

[0043] It can be understood that the speed reduction component 200 can convert the high speed and low torque of the driving component 110 into low speed and high torque and then output it to the lock rod component 300, thereby driving the lock rod component 300 to move. This electronic door lock device can use a driving component 110 with a lower cost, reducing the manufacturing cost.

[0044] It should be noted that the lock hole 101 can also be provided on the rear side wall of the lock body 100, and the lock catch 400 is located at the rear side of the lock body 100, that is, the lock tongue 410 can be inserted into the lock body 100 forward through the lock hole 101, and the lock catch 400 and the lock body 100 can be installed according to the actual situation.

[0045] According to some embodiments of the present utility model, referring to Figure 2 and Figure 3, the deceleration component 200 includes a worm 210 and a gear set 220. The worm 210 is fixedly connected to the driving end of the driving component 110, and the gear set 220 meshes with the worm 210 and the locking rod component 300 respectively. It can be understood that the gear set 220 includes a plurality of gears with increasing number of teeth and meshing successively. The gear with the least number of teeth meshes with the worm 210, and the gear with the most number of teeth meshes with the locking rod component 300. The gear set 220 can convert high speed and low torque into low speed and high torque, so as to facilitate driving the locking rod component 300.

[0046] According to some embodiments of the present invention, referring to Figure 2 , Figure 5 and Figure 6 , the locking rod component 300 includes a locking rod assembly 320 and a swing rod 310. The locking rod assembly 320 is slidably connected to the lock body 100 in the left-right direction, the swing rod 310 is rotatably connected to the lock body 100. A tooth portion is provided at the lower end of the swing rod 310 and is meshed and connected with the gear set 220. The upper end of the swing rod 310 is connected to the locking rod assembly 320. The rotation of the swing rod 310 can drive the locking rod assembly 320 to move in the left-right direction so that the locking rod assembly 320 reciprocates between a first position and a second position.

[0047] Furthermore, referring to Figure 5 and Figure 6 , the locking rod assembly 320 includes a push rod 330, a first slider 340, a second slider 350 and a first spring 360. Both the first slider 340 and the second slider 350 are slidably connected to the lock body 100 in the left-right direction. The first slider 340 is located on the left side of the second slider 350. The push rod 330 passes through the first slider 340 and the second slider 350 at the same time. A first annular convex portion 371 is provided on the outer peripheral wall of the push rod 330, and the first annular convex portion 371 is located inside the first slider 340. The first spring 360 is sleeved on the push rod 330. The right end of the first spring 360 abuts against the second slider 350, and the left end of the first spring 360 abuts against the first annular convex portion 371 so that the left side of the first annular convex portion 371 is pressed against the inner wall of the first slider 340 to prevent the push rod 330 from moving leftward and disengaging from the first slider 340. The first spring 360 is always in a compressed state, that is, the first slider 340 and the second slider 350 always have a tendency to move away from each other. The left end of the push rod 330 extends out of the first slider 340. When the push rod 330 moves to the first position, the left end of the push rod 330 is inserted into the lock groove 420. The swing rod 310 is used to drive the first slider 340 and the second slider 350 to approach or move away from each other, so that the push rod 330 reciprocates between the first position and the second position.

[0048] Furthermore, referring to Figure 5 and Figure 6, a limiting hole 372 is provided at the upper end of the swing rod 310. A first convex column 373 is fixedly provided on the first slider 340, and a second convex column 374 is fixedly provided on the second slider 350. Both the first convex column 373 and the second convex column 374 are inserted into the limiting hole 372. When the swing rod 310 rotates, it can drive the first convex column 373 and the second convex column 374 to approach or move away from each other in the left-right direction.

[0049] It can be understood that under the action of the first spring 360, the first convex column 373 remains in contact with the hole wall of the limiting hole 372 and applies a leftward force to the limiting hole 372, and the second convex column 374 remains in contact with the hole wall of the limiting hole 372 and applies a leftward force to the limiting hole 372. When the swing rod 310 rotates, both the first convex column 373 and the second convex column 374 are in contact with the hole wall of the limiting hole 372. When the swing rod 310 rotates, it can push the first convex column 373 and the second convex column 374 to move, thereby changing the distance between the first convex column 373 and the second convex column 374 in the left-right direction, so that the first convex column 373 and the second convex column 374 approach or move away from each other.

[0050] Viewed from the back to the front, when the swing rod 310 rotates clockwise, when the first convex column 373 and the second convex column 374 approach each other, that is, the first slider 340 and the second slider 350 approach each other, so as to drive the push rod 330 to move from left to right, so that the push rod 330 moves from the first position to the second position.

[0051] Viewed from the back to the front, when the swing rod 310 rotates counterclockwise, under the cooperation of the first spring 360 and the swing rod 310, the first convex column 373 moves away from the second convex column 374, that is, the first slider 340 moves away from the second slider 350, and the push rod 330 moves from right to left, so that the push rod 330 moves from the second position to the first position.

[0052] According to some embodiments of the present invention, referring to Figure 7 and Figure 8 , the lock catch 400 has an inner cavity and an opening facing downwards. A second annular convex portion 430 is provided on the inner peripheral wall of the lock catch 400. The upper end of the lock tongue 410 is inserted into the lock catch 400. A disc 440 is provided at the upper end of the lock tongue 410. The disc 440 is located above the second annular convex portion 430. The diameter of the disc 440 is greater than the inner diameter of the second annular convex portion 430. The lower end surface of the disc 440 can be in contact with the second annular convex portion 430 to prevent the lock tongue 410 from moving downwards and disengaging from the lock catch 400.

[0053] Furthermore, referring to Figure 7 and Figure 8, a second spring 450 is provided inside the latch 400. The upper end of the second spring 450 abuts against the upper inner wall of the latch 400, and the lower end of the second spring 450 abuts against the lock tongue 410. The second spring 450 is always in a compressed state, that is, the second spring 450 exerts a downward force on the lock tongue 410 to ensure that the lock tongue 410 can be stably inserted into the lock body 100.

[0054] Further, referring to Figure 7 and Figure 8 , a cylinder 460 is formed by the downward extension of the upper inner wall of the latch 400. The second spring 450 is arranged inside the cylinder 460, and there is a gap between the lower end of the cylinder 460 and the upper end of the disc 440. It can be understood that the disc 440 can move slightly up and down and swing inside the latch 400, thereby driving the lock tongue 410 to swing slightly, so as to improve the tolerance rate of the assembly of the lock tongue 410. At the same time, it prevents the lock tongue 410 from being stuck inside the lock body 100 when it abuts against the push rod 330. The movement of the push rod 330 can slightly drive the lock tongue 410 to swing, avoiding mutual jamming.

[0055] Further, referring to Figure 7 and Figure 8 , a slide rod 470 is slidably connected inside the latch 400. The lower end of the slide rod 470 passes through the outside of the latch 400. A third spring 480 is provided inside the latch 400. The upper end of the third spring 480 abuts against the latch 400, and the lower end of the third spring 480 abuts against the slide rod 470. The third spring 480 is always in a compressed state. When the lock tongue 410 is inserted into the lock body 100 and the push rod 330 is inserted into the lock groove 420 to fix the latch 400 and the lock body 100 to each other, the lower end of the slide rod 470 abuts against the lock body 100, and the slide rod 470 moves upward to compress the third spring 480. When unlocking, that is, when the push rod 330 disengages from the lock groove 420, the third spring 480 pushes the slide rod 470 to move downward, so that the latch 400 and the lock body 100 move away from each other.
