DETAILED DESCRIPTION

[0018] The utility model is described in detail below with reference to the accompanying drawings.

[0019] Example 1

[0020] An integrated die-cast lock housing assembly includes a housing 1 and an in-mold mounting structure integrally die-cast with the housing 1, the in-mold mounting structure is used to assemble various lock parts of the lock body, the housing 1 is a bottom shell with a cavity, and a lock cover is also adapted on the top. The in-mold mounting structure of the housing 1 includes a lock cover mounting hole 11, a circuit board mounting hole 12, a lock core mounting guide hole 13, a gear mounting hole 14, a dead bolt shift block mounting shaft 15, a dead bolt assembly guide shaft 16, a skew bolt assembly mounting groove 17, a plug-in bolt mounting frame 18, and a motor mounting hole 19 arranged inside the housing cavity, and a dead bolt through groove 20 and a plug-in bolt hole 22 that are interlinked with the cavity are opened on one side of the cavity of the housing 1, and a skew bolt through groove 21 that is interlinked with the skew bolt assembly mounting groove 17 in the cavity.

[0021] The lock cover mounting hole 11 is used to fix the upper lock cover. In this embodiment, there are 5 lock cover mounting holes 11, 4 of which are arranged around the shell 1, and the other is arranged at a predetermined position in the shell cavity. The circuit board mounting hole 12 is used to install the circuit board; the lock core mounting guide hole 13 is used to install the lock core; the gear mounting hole 14 is used to install the gear; the dead bolt block mounting shaft 15 is used to install the dead bolt block; the dead bolt assembly guide shaft 16 is used to provide guidance for the sliding of the dead bolt assembly inside the lock body; the inclined bolt assembly mounting groove 17 is arranged in alignment with the inclined bolt through groove 21 to accommodate inclined bolt components such as inclined bolt springs and inclined bolt blocks; the plug tongue mounting frame 18 is used to install the plug tongue; the motor mounting assembly 19 is used to install the motor box.

[0022] The outer peripheries of the dead tongue through groove 20 and the oblique tongue through groove 21 on one side of the cavity of the shell 1 are respectively provided with a dead tongue noise reduction pad mounting groove 20a for mounting a dead tongue noise reduction pad and an oblique tongue noise reduction pad mounting groove 21a for mounting an oblique tongue noise reduction pad. The dead tongue noise reduction pad mounting groove 20a and the oblique tongue noise reduction pad mounting groove 21a are grooves integrally formed with the shell 1 and sunk inward along the side of the shell 1.
