Specifically, the engagement connection formed by the poking gear teeth 32 and the dead bolt latch teeth 21 is loose connection, namely, a certain gap can exist between the poking gear teeth 32 and the dead bolt latch teeth 21, and on the basis that the poking gear teeth 32 can drive the dead bolt latch teeth 21, the dead bolt assembly 20 can be prevented from crashing the dead bolt latch teeth 21 or poking the gear teeth 32 in the running shake of the motor home by setting a certain gap. In addition, the sizes of the toggle gear teeth 32 and the dead bolt latch teeth 21 can be set to be relatively larger, so that the structural strength of the dead bolt latch teeth is increased, and the reliability of the transmission mechanism is further improved.
As shown in fig. 4, the transmission assembly 30 is provided with a rotation shaft body 33, the rotation shaft body 33 is movably connected to the lock body base 10, the transmission gear 31 is coaxially and fixedly connected with the rotation shaft body 33, and the transmission gear 31 synchronously rotates along with the rotation shaft body 33.

The central angle of the sector gear 35 cannot be too small, which is not beneficial to the connection of the driving gear; nor too large to use, but rather waste material.
When the lock is used, the dead bolt transmission mechanism is arranged on the car lock and is arranged at the car door position of the car, so that the locking effect on the car door is realized. The dead bolt transmission mechanism can be used for locking or unlocking by using the manual rotary handle 12 in a motor home, and can also be used for operating the lock cylinder assembly 11 by using a key outside the motor home, so that the locking or unlocking operation is realized. In addition, the motor home lock can be locked or unlocked through the electric assembly 40. It will be appreciated that the power assembly 40 herein may also be used in conjunction with other components (not shown) to effect remote locking or unlocking operations.
In addition, the rotating shaft body 33 can be movably connected to the lock body base 10 in a sleeve manner, preferably, the rotating shaft body 33 is movably connected to the lock body base 10 through a bearing, and the bearing can enable the rotating shaft body 33 to be connected to the lock body base 10 more reliably and also can rotate more stably.
