Detailed Description

Examples, see fig. 1-5: the built-in electronic lock includes a housing 10. A slide plate 20 is provided in the housing 10 to be slidable vertically. The upper portion of the slide plate 20 is provided with a latch bolt 21 capable of protruding to the outside of the upper side of the housing 10. Namely, the sliding plate 20 drives the bolt 21 to move upwards to lock the bolt 21 after the bolt 21 extends out; conversely, the sliding plate 20 drives the locking bolt 21 to move downwards, so that the locking bolt 21 retracts into the housing 10, and then unlocking is achieved. The way of driving the slide plate 20 to move up and down may be a common mechanical driving way. For example, the housing 10 is also provided with a conventional key cylinder and the like.

Further speaking:

the lower part of the sliding plate 20 is fixedly connected with a lock head connecting plate 30, and the lock head connecting plate 30 can slide up and down in the shell 10. For example, 2 positioning columns arranged one above the other are arranged in the shell 10, 2 strip-shaped positioning holes arranged one above the other are arranged on the lock head connecting plate 30, and the positioning columns are correspondingly clamped in the strip-shaped positioning holes, so that the lock head connecting plate 30 can slide up and down. The lock connecting plate 30 is provided with a strip-shaped slide hole 32 extending in the up-down direction. Meanwhile, a left toothed plate 41 capable of sliding up and down is also slidably arranged in the housing 10. The way that the left toothed plate 41 slides up and down can be similar to the way of the lock connecting plate 30, and is not described again. A left strip-shaped tooth 411 is arranged on the left side edge of the left toothed plate 41, and a left blocking column 412 is further arranged on the left toothed plate 41. The left blocking pillar 412 is clamped in the strip-shaped sliding hole 32, and the left blocking pillar 412 is matched with the lower edge part of the strip-shaped sliding hole 32. That is, in the unlocked state, the left blocking post 412 lightly contacts or is as close as possible to the lower edge of the slide bar hole 32. And a left motor 42 is fixed on the left side of the lock head connecting plate 30 in the housing 10, and a left gear 421 is fixed on a power output shaft of the left motor 42. The left gear 421 engages the left bar tooth 411. Of course, the housing 10 is further provided with a control board for controlling the operation of the left motor 42 and the right motor 52, which will be described below, and the control board is further connected with a trigger device, which may be a fingerprint board, a facial intake system, or the like. That is, after the left motor 42 is operated, the left gear 421 rotates, so that the slide plate 20 is driven to slide downward by the left rack gear 411. At the same time, the left blocking pillar 412 slides downward, and applies a downward pressure to the lower portion of the strip-shaped sliding hole 32, so as to achieve unlocking. Therefore, the built-in electronic lock can be produced after being properly improved on the basis of the existing production line, and the existing lockset can be utilized, so that the production cost of the product is greatly reduced.

Optimizing:

a right toothed plate 51 is also slidably disposed within the housing 10. Similarly, another set of 2 positioning columns arranged one above the other can be arranged in the housing 10, and 2 strip-shaped positioning holes extending in the up-down direction can be arranged on the right toothed plate 51 one above the other, and the 2 positioning columns in the set are correspondingly clamped in the strip-shaped positioning holes, so that the right toothed plate 51 can slide up and down. The right side edge of the right toothed plate 51 is provided with right bar-shaped teeth 511. Meanwhile, a right motor 52 is fixed to the right side of the lock connecting plate 30 in the housing 10, and a right gear 521 is fixed to a power output shaft of the right motor 52. The right gear 521 is engaged with the right rack tooth 511. That is, when the right motor 52 is operated, the right gear 521 rotates, and the slide plate 20 is driven to slide up and down by the right rack gear 511, so that the locking and unlocking can be similarly performed. And, the upper portion of the right side of the lock connecting plate 30 is provided with a strip-shaped notch 31 extending in the up-down direction, and the strip-shaped notch 31 has a lower side 311. Of course, the strip-shaped notch 31 may be a closed strip-shaped opening, and the assembly is easy without the strip-shaped notch 31. A right blocking column 53 is disposed on the left side of the right rack 51, the right blocking column 53 is clamped in the strip-shaped gap 31, and the right blocking column 53 is matched with the lower side 311 of the strip-shaped gap 31. In practice, in the unlocked state, it is preferable to have the right blocking post 53 lightly contact or be as close as possible to the lower side 311 of the strip-shaped notch 31. Thus, when the left motor 42 can drive the sliding plate 20 to move and the lock head connecting plate 30 moves up and down, the right blocking column 53 slides in the strip-shaped notch 31, but the right blocking column 53 and the lock head connecting plate 30 are not affected by each other, and the right motor 52 can be in a standby state without being started; once the left motor 42 is in trouble, the user can activate the right motor 52 to move the right blocking post 53 downward, and the sliding plate 20 can be driven to move downward by applying downward pressure to the lower side 311 of the strip-shaped notch 31, so as to unlock in an unexpected situation. Therefore, the reliability of the lockset is improved by adopting the double motors, but one of the motors (namely the right motor) does not work under the normal state, so that the energy consumption is reduced, and unnecessary resistance is prevented from being increased.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
