AI Technical Summary
In the existing technology, the unlocking operation of electronic locks, especially when children accidentally operate the door handle of the inner door lock device to activate the unlocking function of the electronic lock, can cause children to mistakenly lock the door and open it to go out, resulting in them being locked out.
Design an inner door lock device for an electronic lock that can prevent accidental operation by children, comprising a housing; a door handle mechanism, including a door handle mechanism pivotally mounted in the housing; a door handle mechanism, a deadbolt drive, and a deadbolt drive having an operating part mounted on the housing and movable in a moving direction, and an inner side having an upper locking position groove and an unlocking position groove; the deadbolt mechanism including a positioning member embedded in the housing and detachably positioned in one of the upper locking position groove and the unlocking position groove, and an elastic member disposed on the housing and continuously driving the positioning member to elastically abut against the deadbolt drive.
The anti-locking mechanism drives the first positioning member to move axially through the anti-locking drive component, which then passes through the drive component of the door handle mechanism, thereby preventing the door handle mechanism from being operated to unlock. This effectively prevents children from accidentally operating the door handle unit and unlocking the latch mechanism.

Abstract
Claims
1. An inner door lock device of an electronic lock, characterized by, Suitable for connection to a latch mechanism, and comprising: chassis; The door handle mechanism includes a door handle unit pivotally mounted outside the housing and swingable relative to the housing, a drive member rotatably mounted in the housing and connected to the latch mechanism, and a transmission unit that can be driven to move and is mounted in the housing and is used to connect the door handle unit and the drive member. The transmission unit is driven by the door handle unit, which pivots relative to the housing, to move relative to the housing and to drive the drive member to rotate, thereby causing the drive member to drive the latch mechanism to unlock. The drive member has a positioning hole. The locking mechanism includes a locking drive installed in the housing, a first positioning member that is axially displaceable and passes through the housing and axially abuts against the locking drive, and a first elastic member installed on the housing and continuously driving the first positioning member to elastically abut against the locking drive. When the locking drive moves relative to the housing from the unlocked position to the locked position, it drives the first positioning member to axially displace through the positioning hole of the drive member.
2. The inner door lock device of an electronic lock according to claim 1, wherein The deadbolt drive member can be displaced between the unlocked position and the locked position along a moving direction. The deadbolt drive member has an inner side facing the first positioning member and has an upper locking groove and an unlocking positioning groove recessed on the inner side along the moving direction. The deadbolt mechanism also includes a second positioning member embedded in the housing and detachably positioned in one of the upper locking groove and the unlocking positioning groove, and a second elastic member disposed on the housing and continuously driving the second positioning member to elastically abut against the deadbolt drive member. When the deadbolt drive member is in the unlocked position, the second positioning member is positioned in the unlocking positioning groove. When the deadbolt drive member is in the locked position, the second positioning member is positioned in the upper locking groove.
3. The inner door lock device of an electronic lock according to claim 2, wherein The anti-lock drive has an operating part mounted on the housing and movable in the direction of movement, with the inner side located on the operating part; the anti-lock drive also includes a pusher protruding from the inner side, the pusher having a pusher slope extending obliquely away from the inner side in the direction of movement, when the anti-lock drive moves toward the locked position, the pusher slope pushes the first positioning member so that the first positioning member passes through the positioning hole of the drive member.
4. The inside door lock device of an electronic lock according to claim 2, wherein The anti-lock drive is movable between the unlocked position and the locked position along a moving direction. The anti-lock drive has an operating part, which is mounted on the housing and can be moved along the moving direction. The inner side is located on the operating part. The anti-lock drive also includes a push part protruding from the inner side. The push part has a push ramp extending obliquely away from the inner side along the moving direction, and a positioning surface connected to one end of the push ramp extending away from the inner side and parallel to the inner side. When the anti-lock drive is operated to change to the locked position, the push ramp will push the first positioning member through the positioning hole of the drive member. When the anti-lock drive is in the locked position, the positioning surface will be used for the first positioning member to be positioned against it.
5. An inner door lock device of an electronic lock according to claim 3 or 4, characterized in that, When the anti-lock drive is in the unlocked position, the first positioning member abuts against the operating part. The inner side of the operating part is also recessed with an auxiliary positioning groove that is adjacent to one end of the push slope and is used for the first positioning member to be embedded.
6. The inside door lock device of an electronic lock according to claim 1, wherein The transmission unit includes a push-pull member that is displaceable relative to the housing, the push-pull member being installed in the housing and connected to the door handle unit, and at least one rack installed in the housing and connected to the push-pull member; the drive member has a meshing portion that engages with the rack, a drive portion coaxial with the meshing portion and for connection to the latch mechanism, and a positioning portion having the positioning hole; the push-pull member is driven by the door handle unit to drive the at least one rack to displace relative to the housing, thereby causing the at least one rack to drive the meshing portion to rotate the drive portion.
7. The inside door lock device of an electronic lock according to claim 6, wherein The transmission unit includes two racks that mesh with two opposite sides of the engagement portion of the drive member in the radial direction, and the push-pull member is connected to one of the racks.
8. An inner door lock device of an electronic lock according to claim 6 or 7, characterized in that, The door handle unit includes a door handle body that is pivotally mounted on the outside of the housing and connected to the push-pull member, and a return spring installed between the housing and the door handle body. The door handle body can pivot relative to the housing between an open position and a return position, and synchronously drive the push-pull member to move. The return spring continuously drives the door handle body to pivot towards the return position.
9. The inside door lock device of an electronic lock according to claim 8, wherein The push-pull component has a push-pull portion connected to the rack and a second connecting portion. The door handle body has a door handle portion and a first connecting portion, which are located on opposite sides of their pivot axis radially. The door handle portion is exposed outside the housing. The first connecting portion is movably connected to the second connecting portion. The return spring is connected to the first connecting portion. When the door handle portion of the door handle body is operated to change to the open position, it will drive the first connecting portion to swing and push the push-pull component, and will drive the return spring to elastically deform.
10. The inside door lock device of an electronic lock according to claim 9, wherein The first connecting part and the second connecting part are interlocked and connected.
